Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to a coating and cylindrical
grinding apparatus.
[0003] 2. Description of Related Art
[0004] Round coated work-pieces, such as round coated glass pieces,
are widely used in optical equipments. The round coated work-pieces
are produced by cutting a substrate into many small rectangular
pieces, then cylindrical grinding and coating the small rectangular
pieces, thus to get the round coated work-pieces. The sequence of
the cylindrical grinding process and the coating process can be
exchanged. However, the cylindrical grinding process and the
coating process are executed at different apparatuses, thus, when
the foregoing process is finished, the work-pieces must be unloaded
from an apparatus, transported to another apparatus, loaded on the
another apparatus, then endure the next process. The unloading,
transporting, and loading process prolong the whole time for
producing the work-pieces. Furthermore, the work-pieces may be
polluted in the unloading, transporting, and loading process and
become useless.
[0005] Thus, what is needed is a coating and cylindrical grinding
apparatus that can overcome the above-mentioned limitations.

DETAILED DESCRIPTION
[0012] Referring to FIGS. 1 to 3, a coating and cylindrical
grinding apparatus 100, according to an exemplary embodiment is
shown. The coating and cylindrical grinding apparatus 100 includes
a main body 10, a roller device 20, a liquid jetting device 30, a
heating device 40, a cylindrical grinding device 50, and a support
device 60. The roller device 20, the liquid jetting device 30, the
heating device 40, the cylindrical grinding device 50, and the
support device 60 are all received in the main body 10. The support
device 60 carries a work-piece 90 to process the work-piece 90 with
the roller device 20 and the cylindrical grinding device 50.
[0013] The main body 10 is a housing with a cuboid cavity 101
defined therein to receive the roller device 20, the liquid jetting
device 30, the heating device 40, the cylindrical grinding device
50, and the support device 60. The cavity 101 is substantially
sealed to prevent the cut chips from sputtering out. The main body
10 defines an opening 102 communicating with the cavity 101 for
ingress and egress of the work-piece 90. The opening 102 is
positioned at an end of the cavity 101 along a longitudinal
direction thereof. A slide rail 103 is received in the cavity 101
and is positioned at the bottom of the cavity 101. The slide rail
103 extends along the longitudinal direction of the cavity 101.
[0014] The roller device 20 includes a number of rollers 201
arrayed along the longitudinal direction of the cavity 101. The
roller 201 is barrel-shaped. Each roller 201 is rotatably connected
to the main body 10 by a first shaft 202. The first shaft 202 is
connected to a motor (not shown). The roller 201 is driven by the
motor to rotate. In the present embodiment, the roller 201 is
positioned above the middle portion of the cavity 101.
[0015] The liquid jetting device 30 is mounted on the main body 10
and above the roller device 20. The liquid jetting device 30
includes a liquid container 301 and a nozzle 302. The liquid
container 301 is positioned out of the cavity 101. The nozzle 302
is positioned in the cavity 101. The liquid container 301
communicates with the nozzle 302. The liquid container 301 stores a
coating liquid. The nozzle 302 ejects the coating liquid to the
rollers 201, so that the rollers 201 can coat the coating liquid on
the work-piece 90.
[0016] The heating device 40 heats the work-piece 90 to solidify
the coating liquid to form a coating film. In this embodiment, the
heating device 40 is mounted on the main body 10, and positioned
between the roller device 20 and the cylindrical grinding device
50.
[0017] The cylindrical grinding device 50 is positioned at an end
of the cavity 101 away from the opening 102 along a direction
substantially perpendicular to the longitudinal direction of the
cavity 101. The cylindrical grinding device 50 grinds the outer
diameter of the work-piece 90. The cylindrical grinding device 50
includes a grinding wheel 501. The grinding wheel 501 is
barrel-shaped. The grinding wheel 501 is rotatably connected to the
main body 10 with a second shaft 502. The second shaft 502 is
connected to a motor (not shown). The grinding wheel 501 is driven
by the motor to rotate for grinding the outer diameter of the
work-piece 90. The rotation direction of the grinding wheel 501 is
perpendicular to the rotation direction of the roller 201 because
the rolled surface of the work-piece 90 is perpendicular to the
coated surface of the work-piece 90. The grinding wheel 501 is an
emery wheel.
[0018] The support device 60 includes a drive unit 602, an
elevation unit 603 fixed on the drive unit 602, and a support plate
604 fixed on the elevation unit 603. The drive unit 602 is slidably
mounted on the slide rail 103. The drive unit 602 includes a
stepper motor (not shown). The elevation unit 603 is mounted on the
stepper motor and driven by the stepper motor to move up and down
relative to the roller 201. In the present embodiment, the
elevation unit 603 is a hollow threaded shaft. The support plate
604 is rotatably connected to an end of the elevation unit 603 away
from the drive unit 602. The support plate 604 defines a suction
hole 605 communicating with a vacuum device (not shown) by the
elevation unit 603. The vacuum device is capable of providing
different suction levels to hold the work-piece 90 on the support
plate 604. The support device 60 includes a motor (not shown) for
driving the drive unit 602 to move along the slide rail 103.
[0019] The coating and cylindrical grinding apparatus 100 further
includes a cleaning device 70. The cleaning device 70 is positioned
adjacent to the cylindrical grinding device 50 for jetting cleaning
fluid to the work-piece 90 during in the cylindrical grinding
process. A collection and discharge device (not shown) is
positioned at the bottom of the cavity 101 for collecting chips and
discharging cleaning fluid.
[0020] Referring to FIGS. 3-5, an operation process of the coating
and cylindrical grinding apparatus 100 is shown. The support device
60 is moved to an end of the slide rail 103 near the opening 102,
and the support plate 604 moves down towards the bottom of the
cavity 101. The work-piece 90 is first put on the support plate 604
through the opening 102. The support plate 604 engages the
work-piece 90. Then the support device 60 moves towards the
opposite end of the slide rail 103. The motor of the support device
60 drives the elevation unit 603 to rise until the surface of the
work-piece 90 contacts with the rollers 201. The nozzle 302 ejects
the coating liquid. The rollers 201 turn to coat the coating liquid
on the surface of the work-piece 90. The support device 60
reciprocates along the slide rail 103 to coat the coating liquid on
the surface of the work-piece 90 substantially and evenly. Then the
support device 60 moves to the position beneath the heating device
40. The heating device 40 heats the work-piece 90 to solidify the
coating liquid, thus to form a coating film.
[0021] The support device 60 moves to the grinding wheel 501 when
the coating process is completed. The work-piece 90 makes contact
with the grinding wheel 501. The grinding wheel 501 turns and
rotates the work-piece 90 to grind the work-piece 90 into a
circular shape. The cleaning device 70 jets cleaning fluid at the
work-piece 90 when the work-piece 90 is rolled.
[0022] The support device 60 moves to the position beneath the
heating device 40 again when the work-piece 90 is completely
rolled. The heating device 40 dries the work-piece 90. Finally, the
work-piece 90 is taken out from the opening 102.
[0023] The preceding sequence of the coating process and the
cylindrical grinding process is not fixed. That is, a work-piece 90
can first be coated, then cylindrical ground, or first cylindrical
ground, and then coated.
[0024] It will be understood that the above particular embodiments
are shown and described by way of illustration only. The principles
and the features of the present disclosure may be employed in
various and numerous embodiments thereof without departing from the
scope of the disclosure as claimed. The above-described embodiments
illustrate the scope of the disclosure but do not restrict the
scope of the disclosure.
