[0045] Existing OCA bonding equipment typically uses a robotic arm module to grasp OCA adhesive and then move it to bond it onto the CG product on the bonding platform. OCA adhesive is difficult to grasp, the grasping is unstable, the bonding yield is low, and the machine operation is unstable, which easily leads to fault alarms and affects work efficiency.

[0046] The following is a preferred embodiment of an OCA feeding and bonding device provided by the present invention, which can solve the above technical problems.

[0047] Please refer to Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram showing the distribution of various mechanisms in an OCA feeding and bonding device according to the present invention.

[0048] In the diagram, units with similar structures are represented by the same labels.

[0049] This invention provides an OCA (Optical Characteristic) loading and laminating device, comprising: an OCA hopper mechanism 12, an OCA picking mechanism 13, an OCA loading platform 14, an OCA film-peeling robot 15, an easy-tear adhesive feeding mechanism 16, a steel strip laminating module 11, and a laminating platform 17. The OCA adhesive is used to bond CG screen products. On the side of the laminating platform 17 away from the steel strip laminating module 11, a CG laminating loading and unloading robot 1B, a CG conveying module 18, a CG film-peeling module 19, and a cleaning mechanism 1A can also be installed. The CG film-peeling module 19 and the cleaning mechanism 18 are both located on one side of the CG conveying module 18 to perform film peeling and cleaning operations on the CG products on the CG conveying module 18. The CG laminating loading and unloading robot 1B is located at the end of the CG conveying module 18 near the laminating platform 17. The CG laminating loading and unloading robot 1B is used to pick up the CG products on the CG conveying module 18 and place them on the laminating platform 17 for bonding, and also to pick up and output the bonded products.

[0050] Please refer to Figure 2 In this embodiment, the steel strip bonding module 11 is movably disposed above the OCA loading platform 14 and the bonding platform 1713. The steel strip bonding module 1111 includes: a moving beam 201, a receiving shaft 202, a feeding shaft 203, a steel strip 204, a bonding assembly, a first guide roller 205, and a second guide roller 206.

[0051] The take-up shaft 202 and the unload shaft 203 are rotatably connected to one side of the moving beam 201. Both ends of the steel strip 204 are wound and connected to the take-up shaft 202 and the unload shaft 203, respectively. The bonding assembly, the first guide roller 205, and the second guide roller 206 are movably connected to one side of the moving beam 201. All three components contact the upper surface of the steel strip 204. The bonding assembly is located between the first guide roller 205 and the second guide roller 206. The bonding assembly squeezes the steel strip 204 to pick up the OCA adhesive on the OCA loading platform 14, and then, through the movement of the moving beam 201, bonds the OCA adhesive to the CG product on the bonding platform 1713. Using the steel strip 204 to pick up the OCA adhesive and then bonding it ensures stable gripping and bonding, resulting in a high bonding yield. The steel strip and the OCA adhesive have a small initial set of adhesion. The bottom surface of the OCA adhesive has a film. After the steel strip 204 picks up the OCA adhesive, the film at the bottom of the OCA adhesive will be torn off by a film-tearing robot. After the film is torn off, the bottom surface of the OCA adhesive has a second set of adhesion, which is greater than the first set of adhesion. Therefore, after the bottom surface of the OCA adhesive is bonded to the CG product, the steel strip 204 can gradually tilt and detach from the OCA adhesive.

The second lifting drive assembly 209 and the second connecting frame 216 are disposed on the side of the take-up shaft 202 away from the bonding assembly, so that the bonding assembly has more room to move.

[0056] In this embodiment, the first connecting frame 214 includes two roller frames arranged in parallel, with a first guide roller 205 connected to the bottom of each roller frame. This better guides the steel strip 204 between the first guide roller 205 and the second guide roller 206 to be in a straight strip shape.

The height of the third guide roller 222 is higher than the height of the feeding shaft 203 and the first guide roller 205, which can provide space for components such as the drag chain of the moving beam 201. The steel strip bonding module 1111 also includes a pressing assembly, and the provision of the third guide roller 222 also facilitates the placement of the pressing assembly between the feeding shaft 203 and the third guide roller 222.

[0060] Specifically, the pressing assembly includes a pressing cylinder 223, a first pressing roller 224 and two second pressing rollers 225 arranged in parallel.

[0071] The fixing block 56 is provided with a second sensor 5A for sensing the easy-tear sticker 54. The second sensor 5A can sense whether there is an easy-tear sticker 54 inside the U-shape of the fixing block 56, so that the clamping part 62 can smoothly clamp the easy-tear sticker 54.

[0072] Please refer to Figure 9 The film-tearing robot in this embodiment also includes a rolling mechanism and a clamping cylinder 63 for driving the clamping part 62 to clamp. The rolling mechanism includes a rolling cylinder 65 and a roller 64. The rolling cylinder 65 is disposed on one side of the clamping cylinder 63. The roller 64 is connected to the output end of the rolling cylinder 65 and is located below the clamping part 62. The roller 64 is used to roll the pasting area onto the OCA adhesive film.

[0073] The rolling mechanism may also be equipped with a sensor for sensing whether the easy-tear sticker 54 is held on the clamping part 62, so as to facilitate the easy-to-adhere film removal.

[0074] Furthermore, the film-tearing robot includes a rotating base 69 and a film-tearing motor 66. The rotating base 69 includes a horizontal frustum and a vertical plate. The horizontal frustum is connected to the conveying end of the rotary cylinder. The clamping cylinder 63 and the film-tearing motor 66 are both connected to the vertical plate of the rotating base 69.

[0075] The clamping cylinder 63 is connected to the output shaft of the film-tearing motor 66. Three first sensors 68 are arranged in a ring around the output shaft of the film-tearing motor 66 on the side of the rotating base 69 closest to the clamping cylinder 63. One end of the clamping cylinder 63 is connected to a sensing plate 67 for sensing by the first sensors 68. The control system can determine the position of the clamping cylinder 63 through the first sensors 68.

[0076] The rolling cylinder 65 is connected to the clamping cylinder 63 via a fixed plate. When the clamping cylinder 63 rotates, it drives the roller 64 to roll the viscous area. When the first sensor 68 in the middle senses the sensing plate 67, the roller 64 completes the rolling of the viscous area, and the rolling cylinder 65 controls the roller 64 to retract and stop rolling.

[0077] When the first sensor 68 in the middle senses the sensing plate 67, the roller 64 completes the rolling of the adhesive area. This rolling of the adhesive area means that the boundary between the adhesive area and the OCA adhesive film is also rolled and bonded, i.e., the roller 64 rolls the easy-tear adhesive 54 completely to the film. At this time, the clamping part 62 only clamps the non-adhesive area and rotates and bends it at a certain angle, but does not move the adhesive area away from the OCA adhesive. At this point, the rolling cylinder 65 controls the roller 64 to retract and stop rolling, so as not to affect the subsequent clamping part 62's action of tearing the film from the adhesive area. During the film tearing process, while the clamping cylinder 63 controls the rotation of the clamping part 62, the moving module 61 also coordinates to control the movement of the clamping part 62 to tear the film.

[0078] Please refer to Figure 6 In this embodiment, the OCA material handling mechanism 13 includes a horizontal moving assembly 44, a vertical moving assembly 45, and a material handling assembly. The vertical moving assembly 45 is connected to the output end of the horizontal moving assembly 44, and the material handling assembly is connected to the output end of the vertical moving assembly 45. The material handling assembly includes a first connecting rod 41, a second connecting rod 42, and a suction cup 43. A second connecting rod 42 is adjustablely connected to each of the two ends of the bottom of the first connecting rod 41, and a suction cup 43 is adjustablely connected to each of the two ends of the second connecting rod 42. By adjusting the position of the suction cup 43, the material handling assembly can easily and stably grasp OCA adhesive of different specifications.

[0079] The working principle of this invention is as follows: The OCA material handling mechanism 13 picks up an OCA adhesive from the OCA hopper platform 32, and then passes through the stack detection component 3C. If it is a single sheet of OCA adhesive, the OCA adhesive is placed on the OCA loading platform 14. If it is multiple stacked OCA adhesives, they are thrown onto the waste plate 3B.

[0080] Then, the OCA loading platform 14, carrying the OCA adhesive, moves to a position below the steel strip 204. The height of the driving bonding roller 207 is lower than the height of the first guide roller 205 and the second guide roller 206, causing a downward convexity to form at the bottom of the steel strip 204, i.e., the steel strip is V-shaped. The first lifting drive assembly 208 drives the first guide roller 205 to descend, the second lifting drive assembly 209 drives the second guide roller 206 to descend, and the third lifting drive assembly 210 drives the bonding assembly to descend. Simultaneously, the unloading shaft... 203. A steel strip 204 of a certain length is placed. The protrusion at the bottom of the steel strip 204 will contact the OCA adhesive on the OCA feeding platform 14. Then, the third lifting drive component 210 slides along the guide rail 221, so that the bonding roller 207 rolls along the plane of the OCA adhesive. At the same time, the first lifting drive component 208 controls the first guide roller 205 to descend, and the second lifting drive component 209 controls the second guide roller 206 to descend, so that the steel strip 204 gradually extends horizontally (i.e., straight strip) to stably adhere the OCA adhesive.

[0081] After the OCA adhesive is applied, the film-tearing robot grips the non-adhesive area of ​​the easy-tear sticker 54 and uses the adhesive area to apply the film to the OCA adhesive on the bottom of the steel strip bonding module 11. Then, the film-tearing operation is performed by rotating and moving the clamping part 62 and simultaneously rolling the roller 64.

[0082] After the film is peeled off, the steel belt 204 is raised and the moving beam 201 moves above the bonding platform 1713, which has the CG product on it. Then, the first guide roller 205, the second guide roller 206 and the bonding roller 207 are lowered. At the same time, the rolling of the bonding roller 207 makes the OCA adhesive on the lower surface of the steel belt 204 stably bond with the CG product.

[0083] It should be noted that, as needed, the lifting and lowering of the first guide roller 205, the second guide roller 206, and the bonding roller 207 can also be controlled to make the steel strip 204 tilted, and to make one end of the OCA adhesive on the lower surface of the steel strip 204 first bond with the CG product. Then, the steel strip 204 is controlled to gradually change from tilted to horizontal, while the bonding roller 207 rolls to gradually bond the OCA adhesive to the CG product.

[0084] This completes the feeding and bonding process of an OCA feeding and bonding device according to this preferred embodiment.

[0085] The OCA feeding and bonding equipment of this preferred embodiment uses an OCA material handling mechanism to transport the OCA adhesive from the OCA hopper mechanism to the OCA feeding platform. Then, a steel strip is used to pick up the OCA adhesive and perform bonding. An OCA film-tearing robot grabs the easy-tear adhesive and peels off the film on the OCA adhesive at the bottom of the bonding module. The overall operation is very efficient, the OCA adhesive is picked up stably, and the bonding yield is high.

[0086] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
