Description

  The present invention relates to a tape application stage for attaching an adhesive tape to a peripheral portion of a plate-like body, and a tape application device provided with the same.

  Liquid crystal modules that are widely used as display devices for televisions, personal computers, mobile phones, smartphones, etc. are formed by superimposing and integrating liquid crystal panels, optical sheets, backlights, etc., which are rectangular and flat members, respectively. It is configured. In order to integrate them, a technique is adopted in which a metal frame member is provided on the peripheral edge (four sides) and these are sandwiched, and a technique in which the peripheral edge is bonded with an adhesive tape.

  The tape used for the latter method is called “bezelless tape” or “light-shielding tape”. The reason referred to as “bezelless” is that the frame member (= bezel) can be omitted by using this tape. Moreover, the reason called “light shielding” is because it also has a function of preventing light leakage from the peripheral edge. Hereinafter, the tape is referred to as a “bezelless tape”.

  In the liquid crystal module mounting line, the bezel-less tape attaching process is currently often performed manually by an operator. However, since the bezelless tape is a flexible member, wrinkles and floats are likely to occur during manual work, and improvement in workability of the attaching process is required. Although different from the bezel-less tape, various techniques for attaching the tape are known, and an example will be introduced below.

  As shown in FIG. 9, the tape sticking device disclosed in Patent Document 1 causes an original tape 200 made up of a carrier tape 201 and an adhesive tape piece 202 to be turned back at a knife edge 205, thereby causing an adhesive tape piece 202. Is peeled off from the carrier tape 201, and the peeled adhesive tape piece 202 is stuck to the substrate 204 which is relatively moved in synchronism with the peeling speed by the sticking roller 206. However, in such a tape applicator using the adhering roller 206, the adhering roller 206 covers and hides the adhering position of the adhesive tape piece 202, and the adhering position of the adhesive tape piece 202 and the substrate 204 cannot be confirmed. It cannot be accurately aligned.

  On the other hand, as shown in FIG. 10, the transfer device disclosed in Patent Document 2 has a transparent carrier 301 that carries a transfer body and a substrate 302 that is an adherend, with the alignment marks 303 facing each other. The holding stage 304 is held and a quartz window 305 is provided at a portion corresponding to the alignment mark 303 of the holding stage 304. Therefore, the alignment mark 303 can be imaged by the imaging means 306 through the quartz window 305, and the transparent carrier 301 and the substrate 302 can be accurately aligned.

In addition, the liquid crystal module that is one of the plate-like bodies 40 includes, for example, a liquid crystal panel 41, a polarizing plate 42, a backlight unit 43, and the like.

  The plate-like body stage 20 includes an upper holding plate 21 and a lower holding plate 22 that use unilate (registered trademark, manufactured by Unitika Co., Ltd.) in which polyethylene terephthalate (PET resin) is used as a main raw material and filled with short glass fibers and inorganic fillers. It is configured. In the upper holding plate 21, suction holes 23 which are through holes having a diameter of 0.7 mm are formed at a pitch of 10 mm.

  The lower holding plate 22 is formed with a suction groove 24 corresponding to the suction hole 23 of the upper holding plate 21. The upper holding plate 21 and the lower holding plate 22 are bonded together, and an adsorption mechanism for adsorbing and holding the plate-like body 40 is configured by the adsorption hole 23, the adsorption groove 24, a vacuum pump (not shown), and the like.

  The tape application stage 10 includes a substantially rectangular tape holding table 11 that holds the adhesive tape 30, positioning pins 12 provided on the upper surface of the tape holding table 11, and a base body 13 that supports the tape holding table 11. The tape holder 11 includes an upper transparent plate 14 and a lower transparent plate 15 made of a transparent member such as polycarbonate, and a transparent elastic body 16 made of a light transmissive silicon member.

  The upper transparent plate 14 is provided with a plurality of positioning pins 12 for positioning the adhesive tape 30, and suction holes 17 for sucking the adhesive tape 30 are formed inside the positioning pins 12. Yes. A suction groove 18 corresponding to the suction hole 17 of the upper transparent plate 14 is formed in the lower transparent plate 15. The upper transparent plate 14 and the lower transparent plate 15 are bonded together, and a suction mechanism that sucks the adhesive tape 30 is configured by the suction holes 17, the suction grooves 18, a vacuum pump (not shown), and the like.

  A cutout is formed in the upper transparent plate 14 in the long side portion of the tape holding table 11 that is pressed against the plate-like body 40 by applying the adhesive tape 30, and it is transparent instead of the upper transparent plate 14. An elastic body 16 is incorporated. The transparent elastic body 16 forms substantially the same plane as the upper transparent plate 14 and can hold the adhesive tape 30 having low rigidity horizontally on the tape holding base 11. As the transparent elastic body 16, a sheet-like silicon member having excellent high transparency (transmittance of 90% or more / 400-800 nm) and low hardness (Shore A: 25) is used.

  As shown in FIG. 2, the adhesive tape 30 is placed on the tape holder 11 with the adhesive layer 32 facing upward, positioned by the positioning pins 12, sucked from the suction holes 17, and held by suction. The mount 31 that protects the adhesive layer 32 is provided with a slit 34 that divides the mount 31 into a mount 31A and a mount 31B. Before the adhesive tape 30 is attached to the plate-like body 40, as shown in FIG. Then, the mount 31A of the part to be attached to the plate-like body 40 is removed.

  As shown in FIG. 1, the plate-like body 40 is placed on the plate-like body stage 20 with the first main surface peripheral edge portion 40A to which the adhesive tape 30 is first attached facing downward, and the first main surface peripheral edge portion 40A. Is positioned in a state of protruding from the plate-like body stage 20 to the tape applying stage 10 side, and then sucked from the suction holes 23 and held by suction.

  The tape application stage 10 and the plate-like body stage 20 are mounted on a stage moving mechanism 50 that moves in two directions of the Y axis and the Z axis, or three directions of the XYZ axis shown in FIG. The relative position of the shape body 40 can be controlled. The stage moving mechanism 50 includes an in-plane direction interval (Y axis) between the tape applying stage 10 and the plate-like body stage 20, a lateral displacement (X axis) between the tape applying stage 10 and the plate-like body stage 20, and the like. What is necessary is just to be able to vary the distance (Z axis) between the tape applying stage 10 and the plate-like body stage 20 in the height direction.

  The stage moving mechanism 50 can be composed of, for example, a uniaxial moving mechanism (not shown), or a driving unit such as an air cylinder or an air slider. The stage moving mechanism 50 only needs to be provided on at least one of the tape application stage 10 and the plate-like body stage 20, and the relative position between the adhesive tape 30 and the plate-like body 40 can be determined with only one stage moving mechanism 50. Can be controlled.

  For example, in the case of a narrow frame liquid crystal module, the allowable range of accuracy when the adhesive tape 30 is attached to the plate-like body 40 is 0. The interval between the edge of the adhesive tape 30 and the edge of the polarizing plate 42 of the plate-like body 40 is zero. .2mm or less is set. Here, in the tape applying apparatus 101 of the present embodiment, since the tape holding table 11 of the tape applying stage 10 is formed of a transparent member, for example, imaging is performed from below the tape holding table 11 by the imaging means 60 such as a camera. Accordingly, the edge positions of both the adhesive tape 30 and the polarizing plate 42 of the plate-like body 40 can be confirmed through the tape holding table 11, and high-precision alignment can be performed.

After positioning the adhesive tape 30 on the plate-like body 40, at least one of the tape application stage 10 or the plate-like body stage 20 is raised and lowered by an air cylinder or the like of the stage moving mechanism 50, thereby The adhesive tape 30 can be accurately attached to the location. At this time, since a pressure of about 300 gf / cm ² is applied to the plate-like body 40, the pressure concentrates on the portion of the polarizing plate 42 that protrudes about 0.2 mm from the liquid crystal panel 41, and uneven spots appear on the liquid crystal panel 41. Deterioration of the display quality called “Occasion” may occur.

  In the tape application stage 10 in the present embodiment, the long side portion of the tape holding table 11 pressed by the plate-like body 40 is configured by the transparent elastic body 16, so that the step of the polarizing plate 42 protruding from the liquid crystal panel 41 is provided. Absorbed by the transparent elastic body 16, pressure concentration on the liquid crystal panel 41 can be prevented, and display quality can be prevented from deteriorating. Moreover, since the gap between the polarizing plates 42 is absorbed by the transparent elastic body 16, no gap is generated between the adhesive layer 32 of the adhesive tape 30 and the first main surface peripheral edge portion 40 </ b> A of the plate-like body 40. Can be applied evenly.

  After the adhesive tape 30 is attached to the first main surface peripheral edge 40A of the plate-like body 40, the mount 31B is removed, and the remaining portion of the adhesive tape 30 is the end of the plate-like body 40 and the second main surface. Affixed to these portions while being bent toward the peripheral portion 40B. When the adhesive tape 30 is first applied to the first main surface peripheral edge 40A, since the alignment of the adhesive tape 30 has been completed, it is not necessary to perform new alignment here, and manual work or tape bending is performed. The remaining adhesive tape 30 can be easily attached to the plate-like body 40 using a jig or the like.

  As described above, according to the tape application stage 10 of the present embodiment, the adhesive tape 30 is accurately aligned with respect to the peripheral portion of the plate-like body 40, and the adhesive tape 30 is uniformly formed on the plate-like body 40. Can be pasted.

(Embodiment 2)
Below, the tape sticking apparatus 102 provided with the stage moving mechanism 50 and the imaging means 60 is demonstrated based on FIGS. FIG. 3 is a plan view of the tape applicator 102 according to the present embodiment as viewed from above. FIG. 4 shows a state in which the plate stage 20 is moved to the alignment position by the stage moving mechanism 50 in the tape applicator 102. It is a top view.

  In the tape applicator 102 according to the present embodiment, the plate-like body 20 is placed on the plate-like body stage 20 so that the plate-like body 40 can be arranged substantially parallel to the adhesive tape 30 positioned on the positioning pin 12 of the tape applying stage 10. Forty positioning guides 25 are provided.

  Note that the plate-like body stage 20 may be configured so that the plate-like body stage 20 can be rotated 360 ° by adding a rotary actuator (not shown) to the stage moving mechanism 50. For example, by rotating the plate-like body 40 every 90 °, the adhesive tape 30 can be sequentially attached to the peripheral portion (four sides) of the plate-like body 40.

  As shown in FIG. 4, when the plate-like body stage 20 is moved to the tape applying stage 10 side by the stage moving mechanism 50, the adhesive layer 32 is located below the plate-like body 40 with the first main surface peripheral edge portion 40A facing downward. A pressure-sensitive adhesive tape 30 is placed with the facing upward.

  At this time, the edge of the adhesive tape 30 and the polarizing plate 42 cannot be confirmed from the upper side of the tape sticking device 102 by being shielded by the plate-like body 40, and the relative position of the adhesive tape 30 and the polarizing plate 42 is within an allowable range. Ca n’t fit in.

  For this reason, in the tape sticking apparatus 102 in this embodiment, the imaging means 60 is arrange | positioned under the tape holding stand 11 of the tape sticking stage 10, and the tape holding stand 11 comprised with the transparent member is permeate | transmitted, and the adhesive tape 30 and Each edge position of the adhesive tape 30 and the polarizing plate 42 is confirmed by imaging the polarizing plate 42.

  The imaging means 60 can be constituted by two cameras 60A and 60B provided with a macro lens, for example. The camera 60 </ b> A and the camera 60 </ b> B are disposed below the transparent elastic body 16 of the tape holding table 11, and each of the left and right ends of the adhesive tape 30 is imaged through the tape holding table 11.

  An image captured by each camera is enlarged and displayed on a monitor screen (not shown) by about 25 times. As a result, an allowable interval of 0.2 mm when the adhesive tape 30 and the polarizing plate 42 are attached is displayed on the monitor screen at about 5 mm, and the adhesive tape 30 and the polarizing plate 42 can be accurately aligned. it can. For example, it is possible to align with high accuracy of the order of 10 μm.

  FIG. 5 is an image in which the adhesive tape 30 and the polarizing plate 42 are brought close to each other and each edge position is captured by the left and right cameras 60A and 60B. In the image by the camera 60A, the interval G1 between the left end adhesive tape 30L and the polarizing plate 42L can be confirmed, and in the image by the camera 60B, the interval G2 between the right end adhesive tape 30R and the polarizing plate 42R can be confirmed.

  For the alignment of the adhesive tape 30 and the polarizing plate 42, first, while looking at the captured images of the camera 60A and the camera 60B, either the left end gap G1 or the right end gap G2 is within an allowable range (0.2 mm or less). The plate stage 20 is moved until the distance between the polarizing plate 42 and the adhesive tape 30 is reduced.

  Since the adhesive tape 30 and the polarizing plate 42 are mounted substantially parallel to each other by the positioning pin 12 and the positioning guide 25, the adhesive tape 30 and the polarizing plate 42 are brought close to each other without overlapping to some extent by bringing them closer to each other. Can be made. However, in a narrow frame liquid crystal module or the like, it is necessary to align the distance between the adhesive tape 30 and the polarizing plate 42 at 0.2 mm or less at both the left and right ends, and there is a dimensional tolerance of the adhesive tape 30 and the polarizing plate 42. Since the distance between the left and right ends cannot be kept within the allowable range simply by bringing them close to each other, it is necessary to finely adjust the parallelism of one of the adhesive tape 30 and the polarizing plate 42.

  For example, FIG. 5 shows a state where the gap G1 between the left end adhesive tape 30L and the polarizing plate 42L is within the allowable range, and the gap G2 between the right end adhesive tape 30R and the polarizing plate 42R exceeds the allowable range. As described above, when the gap G2 exceeds the allowable range as in the right end adhesive tape 30R and the polarizing plate 42R, there is a risk of causing light leakage or the like and degrading the display quality.

  FIG. 6 is a plan view showing the configuration of the stage moving mechanism 50 for correcting the parallelism of the tape applying stage 10 that holds the adhesive tape 30. The stage moving mechanism 50 includes a pair of uniaxial moving mechanism 50A and uniaxial moving mechanism 50B disposed below the base body 13 of the tape applying stage 10.

  The uniaxial moving mechanism 50A includes a feed screw 51A, a micrometer head 52A, a slide base 53A, and the like, and the slide base 53A is placed on one axis of the feed screw 51A by rotating the feed screw 51A by the micrometer head 52A. It is designed to move.

  Similarly to the uniaxial moving mechanism 50A, the uniaxial moving mechanism 50B also includes a feed screw 51B, a micrometer head 52B, a slide base 53B, and the like, and the slide base 51B is rotated by rotating the feed screw 51B by the micrometer head 52B. 53B is moved on one axis of the feed screw 51B.

  The feed screw 51 </ b> A and the feed screw 51 </ b> B are arranged in parallel to the center line at equal intervals from the center line of the tape applying stage 10 and the plate-like body stage 20. The feed screw 51A and the feed screw 51B are arranged inside or outside the camera 60A and the camera 60B so as not to interfere with the camera 60A and the camera 60B.

  The base body 13 of the tape applying stage 10 has elastic spacers 54A such as urethane rubber that can be elastically deformed with respect to the slide base 53A of the uniaxial movement mechanism 50A and the slide base 53B of the uniaxial movement mechanism 50B arranged on the left and right sides, respectively. The elastic spacer 54B is coupled to the fixing screw 55A and the fixing screw 55B.

  With the above configuration, the base body 13 is moved in the Y-axis direction together with the slide base 53A and the slide base 53B by moving the slide base 53A of the single-axis movement mechanism 50A and the slide base 53B of the single-axis movement mechanism 50B in synchronization. Can be made.

  Further, for example, when the slide base 53B of the other uniaxial movement mechanism 50B is moved in a state where the slide base 53A of the one uniaxial movement mechanism 50A is stopped, the elastic spacer 54A and the elastic spacer 54B are elastically deformed, and the base body The base body 13 can be tilted in the moving direction of the slide base 53B around the coupling position of the slide base 53A and the slide base 53A.

  It is also possible to tilt the base body 13 in the moving direction of the slide base 53A by moving the slide base 53A of the other single-axis movement mechanism 50A while the slide base 53B of the single-axis movement mechanism 50B is stopped.

  As shown in FIG. 5, when the gap G2 between the right end adhesive tape 30R and the polarizing plate 42R is out of the allowable range, the slide base 53A of the left uniaxial movement mechanism 50A is stopped and the right uniaxial movement mechanism 50B is stopped. By moving the slide base 53B, the base body 13 can be tilted in the moving direction of the slide base 53B so that the gap G2 between the adhesive tape 30R and the polarizing plate 42R can be corrected.

  As described above, in the tape applying apparatus 102 according to the present embodiment, each edge portion of the adhesive tape 30 and the polarizing plate 42 is imaged by the imaging unit 60 from below the tape applying stage 10, and the adhesive tape 30 is applied to the polarizing plate 42. The pasting position can be easily confirmed.

  Moreover, in the tape sticking apparatus 102, since the adhesive tape 30 and the polarizing plate 42 can be mounted substantially parallel to each other by the positioning pins 12 and the positioning guides 25, they can be aligned within an allowable range with a slight inclination correction. Further, the stage moving mechanism 50 configured by a simple uniaxial moving mechanism can perform highly accurate alignment without requiring an expensive θ-axis adjusting stage.

(Embodiment 3)
The tape applicator 103 according to this embodiment is characterized in that a stage reversing mechanism 70 that reverses the tape adhering stage 10 is provided. The tape sticking apparatus 103 in this embodiment is demonstrated based on the top view shown to FIGS.

  The stage reversing mechanism 70 for reversing the tape application stage 10 includes a fixed plate 71 and a rotating plate 72, and a hinge 73 that rotatably couples the rotating plate 72 to the fixed plate 71.

  FIG. 7 is a plan view of the stage reversing mechanism 70 viewed from above the tape applicator 103 and shows a state in which the rotating plate 72 is opened horizontally with respect to the fixed plate 71.

  The fixed plate 71 is fixed to a stage moving mechanism 50 (not shown), and the rotating plate 72 is open to the front side of the fixed plate 71 (opposite to the plate-like body 40) in a state of opening horizontally with respect to the fixed plate 71. Side). The tape application stage 10 is disposed on the rotating plate 72, and is fixed so that the holding surface of the adhesive tape 30 is on the upper side and the transparent elastic body 16 is on the front side.

  FIG. 8 shows a closed state in which the rotation plate 72 of the stage reversing mechanism 70 is rotated to the fixed plate 71 side. The stage reversing mechanism 70 rotates the rotating plate 72 and closes it to the fixed plate 71 side, thereby inverting the tape applying stage 10 up and down and changing the direction of the adhesive layer 32 of the adhesive tape 30 downward. .

  When placing the adhesive tape 30 on the tape application stage 10, the rotating plate 72 is opened horizontally with respect to the fixed plate 71. Thereby, the holding surface of the tape sticking stage 10 fixed to the rotation plate 72 faces upward, and the adhesive tape 30 can be easily placed from above.

  Further, when the adhesive tape 30 is aligned with the polarizing plate 42, the rotating plate 72 is closed to the fixed plate 71 side. As a result, the tape application stage 10 fixed to the rotating plate 72 is turned upside down, and the adhesive tape 30 with the adhesive layer 32 side facing downward is placed above the plate-like body 40 placed on the plate-like body stage 20. Can be placed.

  Thus, the adhesive tape 30 can be disposed on the upper side of the plate-like body 40 by turning the tape applying stage 10 upside down by the stage inversion mechanism 70, and the adhesive tape 30 is covered with the plate-like body 40. The position where the adhesive tape 30 is attached to the polarizing plate 42 can be easily confirmed by allowing the tape holder 11 of the tape application stage 10 to pass through from above. In addition, since the pasting position can be confirmed from above, it is possible to perform alignment using an inexpensive microscope without using an expensive imaging means 60.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.
