DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0029] The following content combines the figures and the
embodiments for detail description of the present invention. It is
particularly pointed out that the following embodiments are only
used to illustrate the present invention, and they are not used to
limit the scope of the present invention. Other embodiments
obtained under the premise of without paying creative labor by the
person ordinary skill in the art are all belong to the claims of
the present invention.
[0030] With reference to FIG. 1 and FIG. 2, in an embodiment of a
transmission system of an LCD panel of the present invention, the
transmission system of the LCD panel includes a guide rail 1 and a
transmission apparatus 2. Wherein, the guide rail 1 can be formed
integrally, and may be formed by connecting multiple rails having
smooth transition connections each other. Here, the "smooth
transition connection" refers to the junction between the two guide
rails is smooth. In the present embodiment, it can use the way of
weld and polish after grinding to achieve. Of course, in another
embodiment, the person skilled in the art can also use other ways
to achieve. For example, a plastic pad be added to the guide rail
1, and the present invention does not limit it.
[0031] Whether the guide rail 1 is formed integrally or the smooth
transition connection by multiple rails, it can reduce the wear of
a wheel of the transmission apparatus 2 based on increasing the
smoothness of the guide rail 1 to increase the service life of the
wheel.
[0032] It is worth mentioning that the invention does not limit the
specific features of the guide rail 1 such as length, width, or
hardness, etc. For example, the total length of the guide rail 1
should be flexibly disposed based on a specific situation of the
entire transmission system, and when the transmission distance is
longer (such as larger factory area), the length of the guide rail
1 is naturally required to be appropriately increased.
[0033] In addition, in order to increase the carrying capacity of
the guide rail 1, the guide rail 1 can utilize the material with
higher hardness such as steel or iron. Of course, when it does not
affect the operation of the transmission system, the guide rail 1
can also utilize other materials. The present invention does not
specifically limit it.
[0034] The above content specifically describes the guide rail 1,
and the following content will describe in detail to the
transmission apparatus 2 of the transmission system.
[0035] The transmission apparatus 2 includes a main body 20 and a
main wheel 21 disposed at the bottom of the main body 20, and the
main wheel 21 abut to the guide rail 1 so that the transmission
apparatus 2 can move along the preset direction of the guide rail
1. There are various fitting ways between the main wheel 21 and the
guide rail 1. For example, a rail groove is disposed on the guide
rail 1, and the main wheel 21 is embedded into the rail groove for
sliding, or the main wheel 21 has a clamping slot for clamping the
guide rail 1 to guide the main wheel 21 to slide along the guide
rail 1. Under the premise of without paying creative labor, the
abutment methods between the other main wheels 21 and the guide
rails 1 thought by the person skilled in the art are ail within the
claims of the present invention.
[0036] The transmission apparatus 2 further includes an auxiliary
wheel 22 disposed at the bottom of the main body 20. The auxiliary
wheel 22 is disposed adjacent to the main wheel 21 and above the
guide rail 1, and the bottom of the auxiliary wheel 22 is higher
than the bottom of the main wheels 21 with a predetermined height.
When the main wheel 21 is abnormal such as loss and damage, the
auxiliary wheel 22 can support the entire transmission apparatus 2
to continue operating in order to prevent the transmission
apparatus 2 from tilt or rollover. In other words, the auxiliary
wheel 22 replaces the neighboring main wheel 21 when it is abnormal
for earning the main body 20 and sliding on the guide rail 1. In
the present embodiment, the predetermined height ranges from 5 mm
to 15 mm such as 10 mm, etc. In another embodiment, the
predetermined height can be flexible disposed based on the
requirement, and the present invention does not limit it.
[0037] Obviously, the fitting method between the auxiliary wheel 22
and the guide rail 1 can also be flexible disposed. The present
invention does not limit it. For instance, the auxiliary wheel 22
may have the same or similar structure with the main wheel 21. In
addition, the material of the main wheel 21 and the auxiliary wheel
22 can also be flexible according to the specific requirement.
[0038] In the present embodiment, when the main wheel 21 rises or
falls because of the abnormality, the auxiliary wheel 22 and the
guide rail abut together to replace the main wheel 21 for
supporting the transmission apparatus 2. It is easily understood,
the present embodiment is to make the bottom of the auxiliary wheel
22 higher than the bottom of the main wheel 21. And its specific
setting way can be flexibly selected. For example, the auxiliary
wheel 22 is selected to have a smaller size than the main wheel 21,
or to lift the center of the auxiliary wheel 22, etc. The present
invention will not limit it.
[0039] It should be particular noted that the auxiliary wheel 22
does not necessarily arrange with the main wheel 21 in the same row
because they can slide on different guide rails. For example, in
another embodiments, they can be disposed on two parallel guide
rails that are an outer guide rail and an inner guide rail, and the
wheel is moving on the outer guide rail, whereas the auxiliary
wheel is moving on the corresponding inner guide rail (and vice
versa), and the auxiliary wheel and the inner guide rail is
separated by a predetermined distance.
[0040] The benefit of the present embodiment is that the
manufacturing cost of the additional guide rails can be omitted,
but it should be understood that this does not constitute a
limitation of the deposition of the guide rail 1 in the present
invention.
[0041] In order to protection, the outer periphery of the main
wheel 21 may be disposed with a rubber pad 210; the outer periphery
of the auxiliary wheel 22 may also be disposed with a rubber pad
220. Since the disposition of the rubber pads is easily to be
understood by the person skilled in the art, it does not repeat
here. It should be understood that the shape, the structure and the
other characteristics of the rubber pads in the present invention
are not limited. Similarly, in other embodiments, it can also use a
plastic pad, a silicone pad, or other elastic pads.
[0042] In the present embodiment, the number of the main wheels 21
may be four, and they are respectively disposed at the four corners
of the bottom of the main body 20. Correspondingly, the number of
the auxiliary wheels 22 may also be four, and each of the auxiliary
wheels 22 is disposed correspondingly to a location adjacent to one
of the main wheels 21.
[0043] It is worth mention that the specific number of the main
wheels 21 and the auxiliary wheels 22 of the present invention are
not limited. In another embodiment, the related technical person
can dispose other number of the wheels with the three, six, or
eight, wheels or auxiliary wheels according to requirement as long
as it is capable of supporting the transmission apparatus 2, and at
least one of the auxiliary wheels corresponds to each of the
wheels.
[0044] In addition to the main body 20, the main wheel 21 and the
auxiliary wheel 22, the transmission apparatus 2 further includes
an alarm unit 24 and an sensor 23 disposed at the connection
location between the main wheel 21 and the bottom of the main body
20. The sensor 23 is for detecting whether the main wheel 21 is
abnormal. The alarm unit 24 is connected to the sensor 23 and is
for generating an alarm when the sensor 23 detects that the main
wheel 21 is abnormal.
[0045] With reference to FIG. 3, in the present embodiment, the
alarm unit 24 and the sensor 23 are connected. It is easy to
understand, in order to obtain the relevant information of the
sensor 23, the alarm unit 24 and the sensor 23 must be connected.
However, their specific connection is belong to the scope can be
easily understood by the person skilled in the art. The present
invention does not repeat it again.
[0046] In the present embodiment, the sensor 23 may be a pressure
sensor. In general, when the sensor 23 detects that the pressure is
changed suddenly or over deviation from its normal value, it
determines that the operation of the system occurring
abnormality.
[0047] When the number of the main wheels 21 is four, the number of
the sensors 23 also can be four, and the four sensors 23 are
corresponding to the four main wheels 21 one by one. In other
words, each of the main wheels 21 has one of the sensors 23
corresponding to it in order to perform a real-time monitoring for
the exerted pressure on each of the main wheels 21. When any of the
main wheels 21 is abnormal the corresponding sensor 23 can timely
detect.
[0048] Of course, in another embodiment, the specific location and
the number of the sensors 23 can be disposed flexibly. For example,
in addition to disposing the sensor 23 above the main wheel 21, it
can also dispose the sensor 23 at the connection location between
the auxiliary wheel 22 and the bottom of the main body 20 in order
to comprehensively monitor the operation data of the transmission
apparatus 2.
[0049] The specific type of the sensor 23 can also be selected
flexibly. In another embodiment, it may also be other types of
sensors. For example, it can dispose a distance sensor at the
bottom of the main body 20 for detecting the distance between the
main body 20 and the guide rail 1 or the distance between the main
body 20 and the ground. Obviously, when the detected distance is
changed, the root cause is that the main wheel 21 has the
abnormality so that the change of the distance can inform the
person that the operation of the apparatus is abnormal That is, the
distance sensor at this time is actually for detecting whether the
main wheel 21 is abnormal and at this time, the distance sensor and
the aforementioned pressure sensor are all disposed at the bottom
of the main body 20.
[0050] The alarm unit 24 cooperates with the sensor 23.
Specifically, the alarm unit 24 generates an alarm when the sensor
23 detects that the main wheel 21 is abnormal. It is easily
understood that the alarm unit 24 may be disposed at an arbitrary
position of the transmission apparatus 2 through a specific way to
connect with the sensor 23. The cooperation method between the
alarm unit 24 and the sensor 23 is belong to the contents can be
easily understood by the person skilled in the art. The present
invention will not repeat here.
[0051] It is worth mention that the alarm unit 24 may be a
mechanical alarm device or an electronic alarm device. The way for
generating a specific alarm may be the form of voice, light, or
sound, etc., and the present invention does not limit the specific
characteristics of the alarm unit 24.
[0052] It should be pointed out that in the present embodiment, the
transmission apparatus 2 may be an automatic crane, and in other
embodiments, tire transmission apparatus 2 may be other mechanical
devices. The present invention does not limit it.
[0053] For a better understanding, the following content assumes
that one of the main wheels 21 falls off and the sensor 23 is a
pressure sensor for describing the operating process of the
transmission apparatus 2.
[0054] First, when one of the main wheels 21 falls off, the
corresponding sensor 23 detects that the exerted pressure on the
wheel 21 is changed. At the same time, the auxiliary wheel 22
corresponding to the main wheel 21 abuts to the guide rail 1 to
support the transmission apparatus 2 for continuing operation;
[0055] Secondly, when the abnormality is detected in the sensor
23/after, the alarm unit 24 generates an alarm to inform the
relevant staff;
[0056] Finally, after receiving the alarm by the relevant staffs
(for example, hearing the alarm bell), they timely arrive on the
scene to understand the situation and decide the next specific step
which should be taken.
[0057] The transmission apparatus of the LCD panel of the present
invention achieve the real-time monitoring for the operation of the
main wheel 21 by disposing the sensor 23 to detect the abnormality.
When the main wheel 21 or the transmission apparatus 2 is abnormal,
the alarm unit 24 generates the alarm and informs the relevant
staffs to prevent the further loss. Meanwhile, when abnormal
conditions occur, such as the tailing of the main wheel 21, the
auxiliary wheel 22 may support the transmission apparatus 2 to
continue operating. Therefore, it effectively prevents the
transmission apparatus 2 from tilt or rollover due to the
abnormality of the main wheel 21.
[0058] Furthermore, in the transmission system, the guide rail 1 is
formed integrally or smooth transition connection such that the
impact force of the guide rail 1 to the main wheel 21 or the
auxiliary wheel 22 can be reduced. Thereby, it greatly improves the
life of the main wheel 21 or the auxiliary wheel 22 and reduces
maintenance and replacement costs.
[0059] With reference to FIG. 4, in an embodiment of an
automatically crane of the present invention, the automatic crane 3
comprises a main body 30, a main wheel 31, an auxiliary wheel 32, a
sensor 33, and an alarm unit 34. Wherein, the main wheel 31, and
the auxiliary wheel 32 are all disposed at the bottom of the main
body 30, and the auxiliary wheel 32 is adjacent to the main wheel
31.
[0060] The bottom of the auxiliary wheel 32 is higher than the
bottom of the main wheel 31 with a predetermined height. The sensor
33 is disposed at the bottom of the main body 30 for detecting
whether the main wheel 31 is abnormal. The alarm unit 34 is for
generating an alarm when the sensor 33 detects that the main wheel
31 is abnormal.
[0061] With reference to FIG. 5, it is easily to understand, in the
present embodiment, the alarm unit 34 of the automatic crane 3 and
the sensor 33 are also connected. The person skilled in the art can
easily understand the relevant content; therefore it does not
repeat here.
[0062] In the present embodiment, the number of the main wheels 31,
the number of the auxiliary wheels 32, and the number of the
sensors 33 are all four, and the four main wheels 31 are disposed
respectively at the tour corners of the bottom of the main body 30;
each of the auxiliary wheels 32 is disposed correspondingly to a
location adjacent to one of the main wheels 31; each of the sensors
33 is disposed correspondingly to one of the main wheels 31.
[0063] Combined with the specific description of the transmission
system of the LCD panel of the present invention, the person
skilled in the art can easily understand the relevant content of
the automatic crane 3, and it does not repeat here. The only thing
that should be pointed out is that in the present embodiment, the
automatic crane 3 may dispose a corresponding guide rail to
cooperate with it, or may not dispose. The present invention will
not limit that.
[0064] The automatic crane 3 of the present embodiment can timely
monitor the operation of the wheel by disposing the sensor 33.
Therefore, it can detect the abnormality, and when the abnormality
occurs, the alarm unit 34 generates an alarm to timely inform the
relevant staffs and prevent the further loss. At the same time,
when the abnormality occurs such as the falling of the main wheel
31, the auxiliary wheel 32 can support the automatic crane 3 to
continue operating so as to effectively prevent the automatically
crane from tilt or rollover due to the abnormality of the main
wheel 31.
[0065] The above embodiments of the present invention are not used
to limit the claims of this invention. Any use of the content in
the specification or in the drawings of the present invention which
produces equivalent structures or equivalent processes, or directly
or indirectly used in other related technical fields is still
covered by the claims in the present invention.
