Description

Technical Field

[0001] This utility model relates to the field of release film tearing equipment, and in particular to a release film tearing device that facilitates waste collection. Background Technology

[0002] In the manufacturing process of precision components such as electronic products, semiconductor devices, and flexible printed circuit boards, a release film is usually applied to their surface or functional layers to protect them from dust and scratches during transportation, storage, and processing. This release film must be precisely and completely removed before the final assembly or packaging process.

[0003] Currently, the removal of release film is mostly accomplished using automated equipment. For example, the utility model patent with authorization announcement number CN211363844U discloses an LCD feeding and film-removing device, which has multi-plane adjustment to adapt to different film-removing positions and angles. However, existing film-removing devices still have several technical difficulties in practical applications: First, since the release film is usually tightly attached to the product surface, and traditional film-removing grippers are mostly fixed structures with poor adaptability, the grippers are prone to touching the product during the film-removing process, resulting in product damage; at the same time, the released film itself is statically charged and thin, and is very easy to be blown away by the wind after being removed from the product. This not only pollutes the production environment, but may also adhere to the surface of equipment or other products, causing secondary pollution or even product scrapping, which brings great trouble to production management. In the above-mentioned prior art, although a waste box is set in the film-removing mechanism, the release film, especially small-area release film, is extremely light and is easy to fly out of the waste box or drift out of the waste box when the release film is thrown into the waste box. Utility Model Content

[0004] Therefore, in order to solve the above problems, this utility model provides a release film tearing device that facilitates waste collection.

[0005] This utility model is achieved through the following technical solution: A release film peeling device for easy waste collection includes: A worktable is used to support the product. The worktable is provided with a plurality of protrusions for lifting the release film, and the bottom of the worktable is movably connected to a first linear module, which is arranged along the y-axis. The clamping mechanism includes a first clamping block and a second clamping block that are vertically movable and synchronously moving towards or away from each other on both sides of the worktable. The gripping mechanism includes a second linear module disposed on the top of the workbench and a robotic arm movably connected to the second linear module. The second linear module is disposed along the x-axis. The robotic arm includes a lifting mechanism and a plurality of gripper assemblies disposed at the bottom of the lifting mechanism. A third linear module is disposed at the bottom of the lifting mechanism. The third linear module is disposed along the x-axis. The gripper assemblies are movably connected to the bottom of the third linear module. The recycling mechanism, located at the bottom of the second linear module, includes a take-up roller and an unwind roller driven by a motor, and a tape disposed between the take-up roller and the unwind roller. The take-up roller and the unwind roller are at the same height and arranged in parallel.

[0006] Preferably, the recycling mechanism further includes two tension rollers disposed between the take-up roller and the unwind roller, the tension rollers being in contact with the lower surface of the tape, and the height of the tension rollers being higher than the height of the take-up roller and the unwind roller.

[0007] Preferably, the first linear module is disposed at the bottom of the worktable, a first guide rail is disposed on one side of the first linear module, a first slide is disposed on the first linear module that can be slidably disposed thereon, a first slider is disposed on the first guide rail, a first support plate is connected to the top of the first slide and the first slider, a rotary motor is disposed on the first support plate, the worktable is driven to rotate along its own axis by the rotary motor.

[0008] Preferably, a fourth linear module is also arranged parallel to the bottom of the second linear module. One end of the fourth linear module is close to the recycling mechanism. Two second guide rails are arranged parallel to both sides of the fourth linear module. A second slide is movably arranged on the fourth linear module. A second slider is movably connected to each second guide rail. The top of the second slide and the two second sliders are connected to a second support plate. The first linear module is arranged on the second support plate.

[0009] Preferably, two first telescopic cylinders are provided on both sides of the bottom of the workbench. The telescopic direction of the two first telescopic cylinders is outward, and the telescopic end of each first telescopic cylinder is connected to a guide plate. Each guide plate is also provided with a second telescopic cylinder. The second telescopic cylinders telescopically extend and retract along the z-axis. One of the second telescopic cylinders is connected to the first clamping block and drives the first clamping block to rise and fall. The other second telescopic cylinder is connected to the second clamping block and drives the second clamping block to rise and fall.

[0010] Preferably, a third slider is movably provided at the bottom of the third linear module, and a gripper assembly is connected to the bottom of the third slider. The gripper assembly includes a mounting base fixed to the bottom of the third slider and a rotary gripper disposed on the mounting base. The rotary gripper can rotate about its axis.

[0011] Preferably, the workbench is provided with a positioning steel plate, and the positioning steel plate is provided with clearance holes that correspond one-to-one with the bosses.

[0012] Preferably, the workbench is further provided with a positioning pin, and the positioning steel plate is provided with a positioning hole corresponding to the positioning pin.

[0013] Preferably, a buffer mechanism is provided at one end of the first linear module. The buffer mechanism includes a buffer platform. A fifth linear module is also provided between the buffer platform and the worktable. The fifth linear module is parallel to the first linear module and located on top of the first linear module. The fifth linear module drives a liftable gripping mechanism to move horizontally. The bottom of the gripping mechanism is provided with multiple vacuum nozzles.

[0014] The beneficial effects of this utility model's technical solution are mainly reflected in: 1. This utility model includes a recycling mechanism comprising a take-up roller, an unwind roller, and an adhesive tape between the take-up roller and the unwind roller. After the release film is removed in batches, multiple grippers can move above the adhesive tape, using the adhesive surface of the tape to adhere the waste release film. This prevents the release film from scattering and allows for collection as soon as the release film comes into contact with the adhesive surface, avoiding contact between the grippers and the product. Simultaneously, the adhesive tape, rotating with the take-up roller and unwind roller, wraps around the waste release film and transports the new adhesive surface to the recycling position, achieving convenient, efficient, and comprehensive release film recycling and preventing release film from contaminating the product and the production environment.

[0015] 2. In this utility model, a protrusion is provided at the release film position of the product. The protrusion is used to lift the release film, making it easier for the gripper to pick up and tear the release film. At the same time, the first clamping block and the second clamping block are used to fix the product on the worktable, thereby preventing the product from shifting during the film tearing process. By setting a positioning steel plate on the product, the film tearing position can also be limited. On the one hand, it protects the product, and on the other hand, it limits the product, improving the accuracy of film tearing and the yield rate.

[0016] 3. In this utility model, the multiple gripper components of the gripping mechanism are liftable, can be translated along the x-axis, and have adjustable distances. They are also coordinated with a worktable that can be translated along the y-axis, so that the release film at various positions on the worktable can be peeled off. This allows it to adapt to products of different sizes and release film distributions. When the grippers are rotary, the peeling angle of the grippers can be adjusted to adapt to release films set at different angles, thereby improving the flexibility of the peeling device and expanding its application range.

[0018] To make the objectives, advantages, and features of this utility model clearer and more detailed, the following non-limiting description of preferred embodiments will be illustrated and explained. These embodiments are merely typical examples of applying the technical solutions of this utility model; any technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

They are only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Furthermore, the terms "first" and "second" in this solution are used for descriptive purposes only and should not be construed as indicating or implying a ranking of importance, or implicitly specifying the number of technical features shown. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] This utility model discloses a release film tearing device that facilitates waste collection, such as... Figure 1 , Figure 2 As shown, it includes: The workbench 1 is used to support the product. The workbench 1 is equipped with multiple protrusions 101 for lifting the release film. The release film typically leaves a tear-off area on the outside of the product. In actual operation, the protrusions 101 are positioned on one side of the product, exactly at the bottom of the tear-off area of ​​the release film. The height of the protrusions 101 should be slightly greater than the height of the product to facilitate subsequent removal of the release film. The protrusions 101 do not directly contact the product, and they block the outside of the product to ensure that the release film does not directly contact the product during removal, thus avoiding damage. The shape, size, position, and number of the protrusions 101 can be adjusted according to the product to be processed, and will not be elaborated here.

[0022] The bottom of the workbench 1 is movably connected to the first linear module 2, which is arranged along the y-axis. The workbench 1 is driven by the first linear module 2 to translate along the y-axis.

[0023] The clamping mechanism includes a first clamping block 3 and a second clamping block 4 that are vertically adjustable and synchronously movable in opposite directions on both sides of the worktable 1. When a product needs to be positioned on the worktable 1, the first clamping block 3 and the second clamping block 4 press against the top sides of the product, thereby cooperating with the worktable 1 to press the product vertically. When the product is placed in front of the worktable 1 or when the product needs to be removed, the first clamping block 3 and the second clamping block 4 rise and move in opposite directions to avoid interference with the product.

[0024] like Figure 3 As shown, the gripping mechanism 5 includes a second linear module 501 disposed on the top of the workbench 1 and a robotic arm movably connected to the second linear module 501. The second linear module 501 is disposed along the x-axis and drives the robotic arm to translate along the x-axis. The robotic arm includes a lifting mechanism 502 and multiple gripper assemblies 505 disposed at the bottom of the lifting mechanism 502. A third linear module 503 is disposed at the bottom of the lifting mechanism 502, and the third linear module 503 is disposed along the x-axis. The gripper assembly 505 is movably connected to the bottom of the third linear module 503. By adjusting the position of each gripper assembly 505 on the third linear module 503, the spacing of different gripper assemblies 505 in the x-axis direction can be adjusted, thereby corresponding to release films located at different x-axis positions and with different spacing. The first linear module 2, the second linear module 501, the lifting mechanism 502, and the third linear module 503 can adopt existing linear module structures, such as existing linear motor structures. This is prior art and will not be described in detail here.

[0025] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the recycling mechanism 6, located at the bottom of the second linear module 501, includes a take-up roller 601 and an unwind roller 602 driven by a motor, and a tape 603 disposed between the take-up roller 601 and the unwind roller 602. The take-up roller 601 and the unwind roller 602 are of equal height and arranged parallel to each other. The tape 603 is wound between the take-up roller 601 and the unwind roller 602. In practical applications, a waste collection area is formed between the take-up roller 601 and the unwind roller 602, with the adhesive side of the tape 603 facing upwards. When the gripper assembly 505 picks up the release film, it places the release film on the adhesive surface of the waste collection area, using the adhesive surface to adhere the release film. Then, the gripper assembly 505 releases the release film and returns to its initial position. After collecting the release film, the take-up roller 601 and the unwind roller 602 rotate synchronously. The take-up roller 601 collects the adhesive tape 603 with the release film adhering to it, while the unwind roller 602 rotates synchronously and conveys a new adhesive surface to the waste collection area, thereby realizing the rapid collection of the release film and the rapid renewal of the waste collection area.

[0026] like Figure 4 , Figure 5 As shown, in some embodiments, the recycling mechanism 6 further includes two tension rollers 604 disposed between the take-up roller 601 and the unwind roller 602. The tension rollers 604 are in contact with the lower surface of the tape 603, and the height of the tension rollers 604 is higher than the height of the take-up roller 601 and the unwind roller 602. The tension rollers 604 are used to adjust the tension of the tape 603 between the take-up roller 601 and the unwind roller 602 to prevent the tape 603 from becoming loose. In a preferred embodiment, the two tension rollers 604 are set at the same height. Both the take-up roller 601 and the unwind roller 602 are air-expanding rollers. The air-expanding rollers are an existing structure and will not be described in detail here.

[0027] like Figure 4 , Figure 5As shown, in one embodiment, the recycling mechanism 6 further includes a first support base 605 and a second support base 606 arranged in parallel. The take-up roller 601 is mounted on the first support base 605, and the unwind roller 602 is mounted on the second support base 606. A first motor 607 is also provided on the first support base 605. The first motor 607 is connected to the take-up roller 601 via a synchronous belt and synchronous pulley structure. The motor shaft of the first motor 607 is connected to a synchronous pulley, and a rotating shaft is coaxially arranged on the take-up roller 601. Another synchronous pulley is connected to the rotating shaft, and the two synchronous pulleys are connected by a synchronous belt, thereby realizing the transmission connection between the first motor 607 and the take-up roller 601. The first motor 607 drives the take-up roller 601 to rotate. A second motor 608 is also provided on the second support 606. The second motor 608 is connected to the unwind roller 602 through the same synchronous belt and synchronous pulley structure, which will not be described in detail here. A first connecting plate 609 is provided on the inner side of the first support 605 (i.e., the side near the second support 606). One tension roller 604 is rotatably connected to the first connecting plate 609 through a bearing. A second connecting plate 610 is provided on the inner side of the second support 606 (i.e., the side near the first support 605). The other tension roller 604 is rotatably connected to the second connecting plate 610 through a bearing.

[0028] like Figure 1 , Figure 2 As shown, in some embodiments, the first linear module 2 is disposed at the bottom of the worktable 1, a first guide rail 14 is disposed on one side of the first linear module 2, a first slide 15 is slidably disposed on the first linear module 2, a first slider is disposed on the first guide rail 14, the top of the first slide 15 and the first slider is connected to a first support plate, a rotary motor is disposed on the first support plate, the worktable 1 is driven to rotate along its own axis by the rotary motor, in one embodiment, the rotary motor is coaxially disposed at the bottom of the worktable 1 and drives the worktable 1 to rotate, in other embodiments, the axis of the rotary motor is perpendicular to the axis of the worktable 1, and the rotary motor and the worktable 1 are connected by two bevel gears whose axes intersect and mesh with each other. The above-mentioned connection structure between the rotary motor and the worktable 1 is all prior art and will not be described in detail here.

[0029] like Figure 1 , Figure 2As shown, in some embodiments, a fourth linear module 10 is also arranged parallel to the bottom of the second linear module 501. One end of the fourth linear module 10 is close to the recycling mechanism 6. Two second guide rails 11 are arranged parallel to both sides of the fourth linear module 10. A second slide (not shown in the figure) is movably arranged on the fourth linear module 10. A second slider 12 is movably connected to each second guide rail 11. The second slide and the top of the two second sliders 12 are connected to a second support plate 13. By connecting the support plate simultaneously through the second slide and the second sliders 12 on both sides, the stability of the support plate during the translation process along the fourth linear module 10 can be ensured. The first linear module 2 is arranged on the second support plate 13. Therefore, when the support plate translates along the fourth linear module 10, it synchronously drives the first linear module 2 and the worktable 1 arranged on the first linear module 2 to translate. The fourth linear module 10 can adopt an existing linear module structure, such as a linear motor, which will not be described in detail here.

[0030] like Figure 6 As shown, in some embodiments, two first telescopic cylinders 16 are provided on both sides of the bottom of the workbench 1. The telescopic directions of the two first telescopic cylinders 16 are arranged outward (i.e., the two first telescopic cylinders 16 are arranged opposite each other). The telescopic end of each first telescopic cylinder 16 is connected to a guide plate 17. Each guide plate 17 is also provided with a second telescopic cylinder 18. The second telescopic cylinder 18 telescopically extends and retracts along the z-axis. One of the second telescopic cylinders 18 is connected to the first clamping block 3 and drives the first clamping block 3 to rise and fall. The other second telescopic cylinder 18 is connected to the second clamping block 4 and drives the second clamping block 4 to rise and fall.

[0031] like Figure 3 As shown, in some embodiments, a third slider 504 is movably provided at the bottom of the third linear module 503. A gripper assembly 505 is connected to the bottom of the third slider 504. The gripper assembly 505 includes a mounting base 5051 fixed to the bottom of the third slider 504 and a rotary gripper 5052 disposed on the mounting base 5051. The rotary gripper 5052 can rotate about its axis. The rotary gripper 5052 adopts an existing rotary gripper product, such as the ERG series electric rotary gripper produced by Suzhou Junduo Robotics Co., Ltd., or other existing gripper products with rotation function, which will not be described in detail here.

[0032] In some embodiments, a positioning steel plate (not shown in the figure) is also included, which is placed on the worktable 1. The positioning steel plate is provided with clearance holes that correspond one-to-one with the protrusions 101. In actual application, the product is first placed on the worktable 1. At this time, the protrusions 101 lift up the tearing area of ​​the product's release film. Then, the positioning steel plate is placed on top of the product. The clearance holes correspond one-to-one with the protrusions 101. The release film is located in the clearance holes, and the lifted tearing area extends out of the clearance holes. Finally, the first clamping block 3 and the second clamping block 4 are moved to the top two sides of the positioning steel plate to fix the positioning steel plate, the product, and the worktable 1. During the tearing process, the gripper assembly 505 only needs to grip the release film exposed outside the clearance holes and will not directly touch the product, so it will not cause product damage.

[0033] In some embodiments, the worktable 1 is further provided with a positioning pin (not shown in the figure), and the positioning steel plate is provided with a positioning hole corresponding to the positioning pin. The height of the positioning pin is higher than the height of the boss 101, thereby limiting the positioning steel plate and the worktable 1 and improving the positioning accuracy.

[0034] like Figure 1 , Figure 2 As shown, in some embodiments, a buffer mechanism 8 is provided at one end of the first linear module 2. The buffer mechanism 8 includes a buffer platform 801 on which products to be peeled off can be stacked. A fifth linear module 9 is also provided between the buffer platform 801 and the workbench 1. The fifth linear module 9 is parallel to the first linear module 2 and located on top of the first linear module 2. The fifth linear module 9 drives a liftable gripping mechanism 7 to translate. Multiple vacuum nozzles 701 are provided at the bottom of the gripping mechanism 7. The vacuum nozzles 701 are used to adsorb products located on the buffer platform 801 and transfer the products to the workbench 1.
