DETAILED DESCRIPTION
[0032] In order to make objects, technical details and advantages
of the embodiments of the disclosure apparent, technical solutions
according to the embodiments of the present disclosure will be
described clearly and completely as below in conjunction with the
accompanying drawings of embodiments of the present disclosure. It
is to be understood that the described embodiments are only a part
of but not all of exemplary embodiments of the present disclosure.
Based on the described embodiments of the present disclosure,
various other embodiments can be obtained by those of ordinary
skill in the art without creative labor and those embodiments shall
fall into the protection scope of the present disclosure.
[0033] Unless otherwise defined, all the technical and scientific
terms used herein have the same meanings as commonly understood by
one of ordinary skill in the art to which the present disclosure
belongs. The terms, such as "first," "second," or the like, which
are used in the description and the claims of the present
application, are not intended to indicate any sequence, amount or
importance, but for distinguishing various components. The terms,
such as "comprise/comprising," "include/including," or the like are
intended to specify that the elements or the objects stated before
these terms encompass the elements or the objects and equivalents
thereof listed after these terms, but not preclude other elements
or objects. The terms, such as "connect/connecting/connected,"
"couple/coupling/coupled" or the like, are not intended to define a

[0034] Usually, after half cutting a top protection film on a panel
by using cutting process, it needs to perform a peeling process to
remove a portion of the top protection film at an edge of the
panel. However, the inventors of the present application has
noticed that, after separating a glue material of the top
protection film to be separated from the panel and transporting the
glue material to a waste port by using a needle tip and a clamping
member, part of the glue material of the top protection film may be
adhered to the needle tip and the clamping member, which influences
subsequent processes; or, such glue material adhered to the needle
tip and the clamping member may be dropped onto a stage of the
machine, which influences subsequent processes, resulting in
various adverse effects. On the other hand, during half cutting the
top protection film on the panel by using cutting process, a
portion of the top protection film corresponding to a position of a
half cutting line would be subjected to a carbonization and
generate particles; moreover, these particles, when dropped onto a
pin, may result in various defects of the panel.
[0035] FIG. 1 is a schematic diagram illustrating a film separation
apparatus separating a film to be separated. As illustrated in FIG.
1, the film separation apparatus includes a mechanical arm 10, a
clamping member 20 disposed on the mechanical arm 10, and a needle
30 disposed on the mechanical arm 10; an end of the needle 30 far
away from the mechanical arm 10 is provided with a needle tip 31.
As illustrated in FIG. 1, a film 40 is disposed on a substrate, and
an upper portion of the film 40 that is to be cut along a cutting
line 50 is referred to as a film 41 to be separated. When the
above-mentioned film separation apparatus is used for separating
the film 41 to be separated, it's possible to, firstly, insert the
needle tip 31 into the film 41 to be separated, and drive the
needle 30 to move horizontally by the mechanical arm 10 to cause an
upwarp portion or a protrusion in the film 41 to be separated, then
clamp the upwarp portion or the protrusion by the clamping member
20, and finally drive the clamping member 20 and the needle tip 31
by the mechanical arm 10 to separate the film 41 to be separated
from the substrate and transport the same to a waste port.
[0036] However, after separating the film 41 to be separated from
the substrate and transporting the same to the waste port by the
needle tip 31 and the clamping member 20, a portion of the film 41
to be separated may be adhered to the needle tip 31 and the
clamping member 20, which influences subsequent processes; or such
portion of film 41 to be separated that is adhered to the needle
tip 31 and the clamping member 20 may be dropped onto a stage of
the machine, which influences subsequent processes, resulting in
various adverse effects. On the other hand, during half cutting the
film 40 on the substrate by using cutting process, a portion of the
film 40 corresponding to a position of a half cutting line would be
subjected to a carbonization and generate particles; moreover,
these particles, when dropped onto a pin, may cause various defects
of the panel.
[0037] Embodiments of the present disclosure provide a film
separation apparatus and a film separation method. The film
separation apparatus includes a mechanical arm, a needle and a
stopping member, the needle has one end connected to the mechanical
arm and the other end provided with a needle tip; the stopping
member includes a connecting rod and a stopper, the connecting rod
having one end connected to the mechanical arm and the other end
connected to the stopper, the needle tip is configured to be
inserted into a film to be separated; the stopper and the needle
tip are configured to move with respect to each other in an
extension direction of the needle so as to separate the film to be
separated from the needle tip. In this way, by an arrangement of
the stopper and by utilizing the relative movement of the stopper
and the needle tip in the extension direction of the needle, the
film separation apparatus allows separating the film to be
separated from the needle tip, so as to prevent the film to be
separated from adhering to the needle tip and avoid various defects
caused thereby.
[0038] Hereinafter, the film separation apparatus and the film
separation method provided by the embodiment of the present
disclosure will be described with reference to the drawings.
[0039] FIG. 2A illustrates a film separation apparatus provided by
an embodiment of the present disclosure. As illustrated in FIG. 2A,
the film separation apparatus 100 includes a mechanical arm 110, a
needle 120 and a stopping member 130; the needle 120 has one end
connected to the mechanical arm 110 and the other end provided with
a needle tip 121; the stopping member 130 includes a connecting rod
131 and a stopper 132, the connecting rod 131 has one end connected
to the mechanical arm 110 and the other end connected to the
stopper 132; the needle tip 121 can be inserted into a film to be
separated; the stopper 132 and the needle tip 121 can move with
respect to each other in the extension direction of the needle 120
so as to separate the film to be separated from the needle tip. It
should be explained that, the above-mentioned relative movement not
only includes a movement along the extension direction of the
needle 120 but also includes movements along other directions, as
long as the movement has a component in the extension direction of
the needle 120.
[0040] When the film separation apparatus provided by the
embodiment of the present disclosure is used for separating a film
(e.g., a top protection film) to be separated on a substrate (e.g.,
display panel), it's possible to, firstly insert the needle tip 121
into the film to be separated, and then move the needle 120
horizontally by the mechanical arm 110 to cause an upwarp portion
or a protrusion in the film to be separated. After separating the
film to be separated from the substrate and transporting the same
to the waste port, it's possible to drive the stopper and the
needle tip to move with respect to each other along the extension
direction of the needle so as to separate the film to be separated
from the needle tip. In this way, by an arrangement of the stopper
and by utilizing the relative movement of the stopper and the
needle tip in the extension direction of the needle, the film
separation apparatus allows separating the film to be separated
from the needle tip, so as to prevent the film to be separated from
adhering to the needle tip and avoid various defects caused
thereby.
[0041] For example, in some examples, a minimum distance between
the stopper 132 and the needle tip 121 is smaller than 20 mm. Thus
it can ensure that the stopper 132 can separate the film to be
separated on the needle tip 121 from the needle tip. It should be
explained that the minimum distance between the stopper and the
needle tip refers to a distance between a portion of the stopper
closest to the needle tip and the needle tip when the stopper and
the needle are located in a same plane parallel to the substrate.
For example, in some examples, as illustrated in FIG. 2A, the
stopping member 130 is fixed on the mechanical arm 110, the film
separation apparatus 100 further includes a first driving device
140 which is disposed on the mechanical arm 110 and can drive the
needle tip 121 to move along the extension direction of the needle
120, so as to move with respect to the stopper 132 in the extension
direction of the needle 120 to separate the film to be separated
from the needle tip 121. That is to say, the stopping member 130 is
fixed with respect to the mechanical arm 110, and the needle tip
121 can move with respect to the stopper 132 under the drive of the
first driving device 140. Because the stopping member 130 can be
fixed on the mechanical arm 110, it has a simple structure, so as
to reduce the cost of the film separation apparatus.
[0042] For example, in some examples, as illustrated in FIG. 2A,
the stopper 132 includes a stop ring, the extension direction of
the needle 120 passes through the stop ring, and the needle tip can
pass through the stop ring. In this way, after passing through the
stop ring, the needle tip can be inserted into the film to be
separated; after retracting the needle tip to a side of the stop
ring far away from the film to be separated and holding the needle
tip there, the stop ring can block the film to be separated on the
needle tip, so as to separate the film to be separated from the
needle tip, which can prevent the film to be separated from
adhering to the needle tip and avoid various defects caused
thereby.
[0043] For example, the above-mentioned stop ring can have a shape
including circle, polygon, ellipse and the like.
[0044] For example, when the above-mentioned stop ring has a circle
shape, a radius of the stop ring is smaller than 20 mm.
[0045] FIG. 2B illustrates another film separation apparatus
provided by an embodiment of the present disclosure. As illustrated
in FIG. 2B, the needle 120 is fixed on the mechanical arm 110, the
film separation apparatus 100 further includes a second driving
device 150 which can drive the stopper 132 to move, so as to move
with respect to the needle tip 121 in the extension direction of
the needle 120 to separate the film to be separated from the needle
tip 121. That is to say, the needle 120 is fixed with respect to
the mechanical arm 110, and the stopper 132 can move with respect
to the needle tip 121 under the drive of the second driving device
150. When the needle 120 is fixed with respect to the mechanical
arm 110, the needle tip 121 can be inserted into the film to be
separated by utilizing a movement of the mechanical arm 110 in a
direction perpendicular to the film to be separated.
[0046] For example, in some examples, as illustrated in FIG. 2B,
the second driving device 150 is disposed in the connecting rod
131, and the second driving device 150 can drive the stopper 132 to
move along an extension direction of the connecting rod 131.
Because the second driving device can be disposed in the connecting
rod, a volume and an integration level of the film separation
apparatus can be reduced.
[0047] For example, the second driving device 150 can include a
driving device such as a hydraulic cylinder.
[0048] For example, embodiments including the first driving device
and the second driving device respectively have been introduced
above, but the embodiment of the present disclosure is not limited
thereto. Any driving device disposed on the mechanical arm that can
drive at least one of the stopper and the needle tip can allow the
stopper and the needle tip to move with respect to each other in
the extension direction of the needle.
[0049] For example, in some examples, as illustrated in FIG. 2A and
FIG. 2B, the film separation apparatus further includes a clamping
member 160 which is disposed on the mechanical arm 110 and can
clamp the film to be separated.
[0050] FIG. 3 is a schematic diagram illustrating a film separation
apparatus provided by an embodiment according to the present
disclosure separating a film to be separated. As illustrated in
FIG. 3, a film 200 is disposed on a substrate 300, and an upper
portion of the film 200 that is isolated by a cutting line is
referred to as a film 210 to be separated. It's possible to,
firstly, insert the needle tip 121 into the film 210 to be
separated, and then drive the needle 120 to move horizontally by
the mechanical arm 110 to cause an upwarp portion or a protrusion
in the film 210 to be separated. At this moment, clamping the
upwarp portion or the protrusion by the clamping member 160, and
then completely separating the film 210 to be separated from the
substrate 300 by the needle 121 and the clamping member 160 which
are driven by the mechanical arm 110; moreover, after transporting
the film 210 to be separated to the waste port, driving the stopper
132 and the needle tip 121 to move with respect to each other in
the extension direction of the needle 120 so as to separate the
film 210 to be separated from the needle tip 121.
[0051] FIG. 4A is a schematic diagram illustrating a clamping
member in a film separation apparatus provided by an embodiment
according to the present disclosure. As illustrated in FIG. 4A, the
clamping member 160 can include a first clamping rod 161, a second
clamping rod 162, and a first electric motor 163; the first
clamping rod 161 is fixed with the mechanical arm 110; the second
clamping rod 162 is hinged with the first clamping rod 161; the
first electric motor 163 is disposed at a hinged position where the
first clamping rod 161 is hinged with the second clamping rod 162,
and can drive an end of the second clamping rod 162 far away from
the hinged position to rotate about the hinged position; that is to
say, the end of the second clamping rod 162 far away from the
hinged position moves in an arc around the hinged position rather
than revolving on its own axis. For example, the first electric
motor is not limited to be disposed at the hinged position where
the first clamping rod 161 is hinged with the second clamping rod
162, but can be disposed at any other appropriate positions as long
as it allows driving the end of the second clamping rod 162 far
away from the hinged position to rotate about the hinged position.
Thus, the clamping member can pass through a space between the
above-mentioned unwarp portion and the substrate by means of a
rotation of the second clamping rod so as to clamp the film to be
separated, and can also separate the film to be separated from the
substrate under the drive of the mechanical arm. Moreover, after
transporting the film to be separated to the waste port, in
addition to the relative movement of the stopper and the needle tip
in the extension direction of the needle which can separate the
film to be separated from the needle tip, it's also possible to
restore the second clamping rode to a vertical state by means of a
rotation of the second clamping rod, that is, a state where the
second clamping rod is parallel to the first clamping rod, so as to
prevent the film to be separated from adhering to the clamping
member.
[0052] FIG. 4B is a schematic diagram illustrating a clamping
member in another film separation apparatus provided by an
embodiment according to the present disclosure. As illustrated in
FIG. 4B, the clamping member 160 further includes a second electric
motor 164; the second electric motor 164 is disposed at an end of
the second clamping rod 162 close to the hinged position, and can
drive the second clamping rod 162 to revolve on its own axis. After
transporting the film to be separated to the waste port, by
revolving the second clamping rod, it can further prevent the film
to be separated from adhering to the clamping member. It should be
explained that, after transporting the film to be separated to the
waste port, the revolving and rotation of the second clamping rod
can be performed at the same time; that is, it's possible to
restore the second clamping rod to the vertical state and meanwhile
revolving the second clamping rod, so as to further prevent the
film to be separated from adhering to the clamping member.
[0053] FIG. 5 is a schematic diagram illustrating a working process
of a clamping device in a film separation apparatus provided by an
embodiment according to the present disclosure. As illustrated in
FIG. 5, when the needle tip 121 is inserted into the film 210 to be
separated, the mechanical arm 110 drives the needle 120 to move
horizontally so as to cause an upwarp portion or a protrusion in
the film 210 to be separated, and then the first electric motor 163
drives the second clamping rod 162 to rotate in an arc around the
hinged position where the first clamping rod 161 is hinged with the
second clamping rod 162, that is, rotating about the
above-mentioned hinged position, so as to drive the second clamping
rod 162 to pass through the space between the above-mentioned
upwarp portion or protrusion and the substrate 300 to clamp the
film 210 to be separated. The mechanical arm 110 drives the needle
tip 121 and the second clamping rod 162 to move so as to completely
separate the film 210 to be separated from the substrate 300. After
the film 210 to be separated is transported to the waste port, the
stopper 132 and the needle tip 121 are driven to move with respect
to each other in the extension direction of the needle 120, so as
to separate the film 210 to be separated from the needle tip 121;
the first electric motor 163 drives the second clamping rod 162 to
rotate and restore to the vertical state, so as to prevent the film
210 to be separated from adhering to the clamping member 160.
Moreover, after the film to be separated is transported to the
waste port, revolving the second clamping rod 162 while restoring
the second clamping rod 162 to the vertical state, so as to further
prevent the film 210 to be separated from adhering to the clamping
member 160.
[0054] For example, in some examples, the film separation apparatus
100 can further include an adsorption device 170 which is disposed
on the mechanical arm 110 and can generate an adsorption force to
adsorb particles. FIG. 6 is a schematic diagram illustrating an
adsorption device provided by an embodiment according to the
present disclosure; in order to clearly illustrate the adsorption
device 170, FIG. 6 omits some components such as the needle, the
stopping member and the clamping member. As illustrated in FIG. 6,
the adsorption device 170 can include a plurality of adsorption
holes 171 which can generate an adsorption force by means of
negative pressure. The plurality of adsorption holes 171 are
disposed at a side of the mechanical arm 110 close to the film to
be separated. In this way, when there are particles at a position
of a cutting line of the film to be separated, the adsorption
device can be utilized to remove the particles by the adsorption
force while separating the film to be separated, which prevents the
particles from dropping onto the substrate and hence can avoid
various defects caused by the particles dropping onto the
substrate.
[0055] For example, the adsorption device can include a vacuum
adsorption device.
[0056] An embodiment of the present disclosure further provides a
film separation method. FIG. 7 is a flow chart illustrating a film
separation method provided by an embodiment according to the
present disclosure. As illustrated in FIG. 7, the method includes
the following steps S701-S704.
[0057] Step S701, inserting a needle tip of a needle into a film to
be separated disposed on a substrate. 10058o Step S702, moving the
needle and causing an upwarp portion in the film to be
separated.
[0058] Step S703, moving the needle to drag the film to be
separated, so as to separate the film to be separated from the
substrate.
[0059] Step S704, driving a stopper and the needle tip to move with
respect to each other in an extension direction of the needle so as
to separate the film to be separated from the needle tip.
[0060] The film separation method provided by the embodiment of the
present disclosure, when used for separating a film (e.g., top
protection film) to be separated, firstly can allow the needle tip
of the needle to be inserted into the film to be separated, and
then drives the needle to move horizontally by the mechanical arm
so as to cause an upwarp portion or protrusion in the film to be
separated. After separating the film to be separated from the
substrate and transporting the same to the waste port, the stopper
and the needle tip can be driven to move with respect to each other
in the extension direction of the needle so as to separate the film
to be separated from the needle tip. In this way, the film
separation apparatus can separate the film to be separated from the
needle tip by arranging the stopper and by utilizing the relative
movement of the stopper and the needle tip in the extension
direction of the needle, so as to prevent the film to be separated
from adhering to the needle tip and to avoid various defects caused
thereby.
[0061] For example, in some examples, the film separation method
further includes: after moving the needle to cause an upwarp
portion in the film to be separated, clamping the upwarp portion by
a clamping member. Subsequently, moving the clamping member and the
needle tip to drag the film to be separated, so as to separate the
film to be separated from the substrate, which ensures a separation
of the film to be separated from the substrate by utilizing the
clamping member.
[0062] For example, in some examples, a minimum distance between
the needle tip and the stopper is smaller than 20 mm. In this way,
it ensures that the film to be separated on the needle tip can be
separated from the needle tip by the stopper.
[0063] For example, in some examples, driving the stopper and the
needle tip to move with respect to each other in the extension
direction of the needle so as to separate the film to be separated
from the needle tip includes: driving the needle tip to move along
the extension direction of the needle by using a first driving
device so that the needle tip moves with respect to the stopper to
separate the film to be separated from the needle tip. In other
words, the topper is fixed relatively, and the needle tip can move
with respect to the stopper under the drive of the first driving
device. Because the stopper is fixed relatively, it has simple
structure so as to reduce the cost of the film separation
method.
[0064] For example, in some examples, the stopper includes a stop
ring, the extension direction of the needle passes through the stop
ring, and the needle tip can pass through the stop ring. In this
way, after passing through the stop ring, the needle tip can be
inserted into the film to be separated; after retracting the needle
tip to a side of the stop ring far away from the film to be
separated and holding the needle tip there, the stop ring can block
the film to be separated on the needle tip so as to separate the
film to be separated from the needle tip, thereby preventing the
film to be separated from adhering to the needle tip and avoiding
various defects caused thereby.
[0065] For example, the above-mentioned stop ring can have a shape
including circle, polygon, ellipse and the like.
[0066] For example, when the above-mentioned stop ring has a circle
shape, a radius of the stop ring is smaller than 20 mm.
[0067] 1 For example, driving the stopper and the needle tip to
move with respect to each other in the extension direction of the
needle so as to separate the film to be separated from the needle
tip includes: driving the stopper to move by using a second driving
device so that the stopper moves with respect to the needle tip in
the extension direction of the needle to separate the film to be
separated from the needle tip. In other words, the needle can be
fixed relatively, and the stopper can move with respect to the
needle tip under the drive of the second driving device.
[0068] For example, in some examples, the film separation method
can further include: adsorbing particles on the substrate by an
adsorption device. In this way, when there are particles at a
position of a cutting line of the film to be separated, the
adsorption device can be utilized to remove the particles by an
adsorption force while separating the film to be separated, which
prevents the particles from dropping onto the substrate and hence
can avoid various defects caused by the particles dropping onto the
substrate.
[0069] For example, in some examples, the film separation method
further includes: before inserting the needle tip of the needle
into the film to be separated disposed on the substrate, cutting a
film by using a cutting process to produce the film to be
separated.
