Description

Technical Field

[0001] This utility model relates to the field of release film peeling equipment, and in particular to a batch release film peeling device. Background Technology

[0002] Flexible printed circuit boards (FPCs) and some precision electronic products and components typically have a release film attached to their surface during manufacturing. This film protects the delicate circuits and pads from scratches, oxidation, or contamination during transportation, storage, and processing. Before subsequent assembly or disassembly processes, this release film needs to be precisely and efficiently peeled off. Currently, the industry still heavily relies on manual operation for peeling the release film from batches of FPCs. However, because flexible printed circuit boards and similar products are usually made of soft materials, improper force or operational errors during manual peeling and tearing can easily cause creases, scratches, or even tears in the FPC products, resulting in product scrap and making it difficult to guarantee a high yield rate.

[0003] To address these issues, some semi-automatic or assisted release film removal devices have emerged in the prior art. For example, the invention patent CN116061541B discloses a batch release film removal mechanism and method that uses adhesive tape to remove the release film from the product surface. A steel plate is used for positioning and protecting the product, and before removal, a pressure head is applied to the release film to increase the adhesive strength of the tape. However, this removal device and method still cannot guarantee that all film removal can be completed in a single pass. Repeated removal may cause the tape to come into contact with the already removed product, leading to damage. Strong adhesive tape can also easily damage the product during the tearing process. Furthermore, because the release film adheres tightly to the product surface, and flexible printed circuit boards are relatively thin, the release film may not be able to protrude beyond the clearance holes of the steel plate after it is covered, resulting in removal failure. Utility Model Content

[0004] Therefore, in order to solve the above problems, this utility model provides a batch release film peeling device.

[0005] This utility model is achieved through the following technical solution: A batch release film peeling device, comprising: The buffer rack includes multiple vertically arranged guide screws and a material carrier plate passing through the guide screws; A film-peeling platform is set on one side of the buffer rack. A positioning plate is set on the top of the film-peeling platform. The upper surface of the positioning plate is provided with a number of positioning protrusions for lifting the product release film. A positioning steel plate is placed on top of the positioning plate to cooperate with the positioning plate in pressing the product up and down. The positioning steel plate is provided with a number of positioning holes, and the positioning holes are provided one-to-one with the positioning bosses, so that the positioning bosses pass into their corresponding positioning holes. A film-tearing mechanism, located at the top of the film-tearing platform, includes at least one gripper, which is translatably mounted on the top of the film-tearing platform by a first linear module. The conveying mechanism includes a second linear module disposed between the film-tearing mechanism and the buffer rack. The second linear module is perpendicular to the first linear module. The film-tearing platform is driven by the second linear module to translate between the buffer rack and the film-tearing mechanism.

[0006] Preferably, the buffer rack includes two sets of first lead screw groups disposed on the front and rear sides of the material carrier plate and two sets of second lead screw groups disposed on the left and right sides of the material carrier plate. Each set of first and second lead screw groups is provided with at least two guide screws. The bottom of the two sets of first lead screw groups is provided with a first guide rail. The two sets of first lead screw groups are disposed on two first sliders and the two first sliders are movably connected to the first guide rail. The bottom of the two sets of second lead screw groups is provided with a second guide rail. The two sets of second lead screw groups are disposed on two second sliders and the two second sliders are movably connected to the second guide rail. The first guide rail and the second guide rail are spaced apart in the height direction and are perpendicular to each other.

[0007] Preferably, the bottom of the carrier plate is provided with a lifting mechanism. The lifting mechanism includes a linear drive mechanism for driving the carrier plate to rise and fall, and a guide frame connected to the bottom of the carrier plate. The guide frame includes a support platform arranged parallel to the bottom of the carrier plate and multiple guide columns arranged vertically on the support platform. The guide columns are connected to the support platform through guide sleeves, and the top of the guide columns is connected to the bottom of the carrier plate.

[0008] Preferably, the top of the carrier plate is also provided with a position sensor for detecting the height of the carrier plate.

[0009] Preferably, it also includes a transfer mechanism, which includes a third linear module arranged parallel to the top of the second linear module. The third linear module is disposed between the buffer rack and the film-tearing mechanism. A liftable robotic arm is provided on the third linear module, and a vacuum nozzle for adsorbing products is provided at the bottom of the robotic arm.

[0010] Preferably, the third linear module is movably connected to a first slide, and the robot includes a fourth linear module disposed on the first slide. The fourth linear module is disposed along the height direction and drives the first mounting base to rise and fall. The bottom of the first mounting base is provided with a material picking bracket, and the bottom of the material picking bracket is provided with multiple vacuum nozzles.

[0011] Preferably, a detection mechanism is further provided between the buffer rack and the film-tearing mechanism, the detection mechanism including a scanning camera disposed on the top of the second linear module.

[0014] The beneficial effects of this utility model's technical solution are mainly reflected in: 1. In this utility model, a positioning boss is used to lift the release film from the edge of the product. A positioning steel plate and a positioning plate are used to position the product vertically. The positioning boss and the release film of the product are avoided through positioning holes, thus ensuring that the release film is lifted outside the positioning holes. This facilitates the gripper to grasp and tear off the release film, and also facilitates precise positioning of the tearing position. It can ensure efficient film tearing of large batches of products. When repeated film tearing is required in the future, the gripper can be used to tear the film without damaging the product with the release film removed, and without leaving adhesive residue on the surface of the positioning steel plate or other structures.

[0015] 2. In this utility model, when the buffer rack is equipped with two sets of movable lead screw groups, the front and rear, left and right lead screw groups can be adjusted in position according to products of different sizes and shapes, thus making it widely applicable to the storage of different types of products. By monitoring the product height in real time through position sensors and adjusting the height of the loading plate in real time in conjunction with the lifting mechanism, the number of products in the buffer rack can be detected in real time, and it is convenient to accurately pick up materials.

[0020] This utility model discloses a batch release film peeling device, such as... Figures 1-5 As shown, it includes: The buffer rack 1 includes multiple vertically arranged guide screws 101 and a material carrier plate 102 passing through the guide screws 101. The material carrier plate 102 can have through holes at positions corresponding to the guide screws 101 to facilitate the passage of the guide screws 101. The guide screws 101 are used to determine the placement position of the material carrier plate 102. On the other hand, the material carrier plate 102 can also move up and down along the guide screws 101 to accommodate the stacking thickness of the products. At this time, the guide screws 101 are also used to guide the movement direction of the material carrier plate 102. The number and position of the guide screws 101 can be adjusted according to actual needs, and the size of the material carrier plate 102 can also be adjusted according to the shape and size of the products, which will not be elaborated here.

[0021] A film-peeling platform 3 is located on one side of the buffer rack 1 and is used to support the product during the film-peeling process. A positioning plate 301 is provided on the top of the film-peeling platform 3. The upper surface of the positioning plate 301 is provided with several positioning protrusions 302 for lifting the release film of the product. In practical applications, the release film attached to the product surface usually leaves a portion extending beyond the product's exterior. This ensures complete coverage of the product surface and facilitates subsequent removal of the release film. In actual operation, the positioning protrusions 302 are positioned on one side of the product, and their height should be slightly greater than the product's height. The positioning protrusions 302 do not directly contact the product but instead lift the portion of the release film extending beyond the product, facilitating subsequent removal of the release film and ensuring that the release film does not directly contact the product during removal, thus avoiding damage. The shape, size, position, and number of the positioning protrusions 302 can be adjusted according to the product to be processed, and will not be elaborated upon here.

[0022] A positioning steel plate 4 covers the top of the positioning plate 301 to work together with the positioning plate 301 to press the product down. The positioning steel plate 4 is provided with a plurality of positioning holes 401, and the positioning holes 401 are provided one-to-one with the positioning bosses 302, so that the positioning bosses 302 pass into their corresponding positioning holes 401. When the positioning bosses 302 push up the edge of the release film, the edge of the release film will be raised to the outside of the positioning holes 401, which facilitates the subsequent tearing of the film. The shape, size, position and number of the positioning holes 401 can be adjusted according to actual needs, which will not be described in detail here.

[0023] The film-tearing mechanism 5 is located on top of the film-tearing platform 3 and includes at least one gripper 501. The gripper 501 is driven by the first linear module 6 and can be translatably disposed on top of the film-tearing platform 3. The number and arrangement of the grippers 501 can be adjusted according to actual needs, which will not be elaborated here.

[0024] The conveying mechanism includes a second linear module 7 disposed between the film-tearing mechanism 5 and the buffer rack 1. The film-tearing platform 3 is driven by the second linear module 7 to translate between the buffer rack 1 and the film-tearing mechanism 5, thereby facilitating product loading and film tearing. The second linear module 7 is perpendicular to the first linear module 6. In one embodiment, the second linear module 7 is disposed along the x-axis and the first linear module 6 is disposed along the y-axis. Therefore, by cooperating with the first linear module 6 and the second linear module 7, the relative positions of the gripper 501 and the film-tearing platform 3 in the x-axis and y-axis directions can be adjusted in real time, thereby ensuring that the release film on each product on the film-tearing platform 3 is removed.

[0025] like Figure 6As shown, in some embodiments, the buffer rack 1 includes two sets of first lead screw groups 103 disposed on the front and rear sides of the material carrier plate 102 and two sets of second lead screw groups 104 disposed on the left and right sides of the material carrier plate 102. The front side of the material carrier plate 102 refers to the side closest to the film-tearing mechanism 5. Each set of first lead screw groups 103 and second lead screw groups 104 is provided with at least two guide screws 101. The bottom of the two sets of first lead screw groups 103 is provided with a first guide rail 105, which is mounted on two first sliders 106. The two first sliders 106 are movably connected to the first guide rail 105. The bottom of the two sets of second lead screw groups 104 is provided with a second guide rail 107, which is mounted on two second sliders 108. The two second sliders 108 are movably connected to the second guide rail 107. The first guide rail 105 and the second guide rail 104 are connected to the second guide rail 107. Two guide rails 107 are spaced apart in the height direction, and the first guide rail 105 is perpendicular to the second guide rail 107. With the above structure, the relative distance and position of the two sets of first lead screw groups 103 and the two sets of second lead screw groups 104 can be adjusted according to actual needs. After adjusting the relative distance of each lead screw group, the material plate 102 that is adapted to the position of each guide lead screw 101 can be replaced, thereby adapting to the storage of products of different sizes. In one embodiment, the first guide rail 105 is set at the bottom of the second guide rail 107. The first guide rail 105 is set on a support platform 109, and the second guide rail 107 passes through the support platform 109. One first slider 106 moves in the area where the first guide rail 105 extends out of the support platform 109 to the left, and the other first slider 106 moves in the area where the first guide rail 105 extends out of the support platform 109 to the right, thereby ensuring that the structures do not interfere with each other.

[0026] like Figure 6As shown, in some embodiments, a lifting mechanism is provided at the bottom of the carrier plate 102. The lifting mechanism includes a linear drive mechanism 110 for driving the carrier plate 102 to rise and fall. The linear drive mechanism 110 can adopt an existing linear drive structure. In one embodiment, the linear drive mechanism 110 adopts a ball screw structure driven by a motor, including a screw and a screw nut disposed on the screw. The carrier plate 102 is connected to the screw nut, and the motor drives the screw nut and the carrier plate 102 to translate along the screw, thereby realizing the lifting. The lifting mechanism also includes a guide frame connected to the bottom of the carrier plate 102. The support frame includes a support platform 111 parallel to the bottom of the material carrier plate 102 and multiple guide columns 112 vertically arranged on the support platform 111. The guide columns 112 are connected to the support platform 111 through guide sleeves 113, and the top of the guide columns 112 is connected to the bottom of the material carrier plate 102. The guide columns 112 pass through the guide sleeves 113 provided on the support platform 111. When the linear drive mechanism 110 drives the material carrier plate 102 to rise and fall, the guide columns 112 translate along the axial direction within the guide sleeves 113 to improve the stability of the material carrier plate 102 during the rising and falling process.

[0027] like Figure 6 As shown, in some embodiments, a position sensor 2 for detecting the height of the material carrier 102 is also provided on the top of the material carrier 102. The position sensor 2 can be an existing height sensor or a contact sensor. The position sensor 2 can be set at a specific height position for real-time detection of the material taking status of the product.

The vacuum nozzle 905 adopts an existing vacuum nozzle 905 product, which will not be described in detail here. In one embodiment, a first slide 901 is movably connected to the third linear module 8, and the robotic arm includes a fourth linear module 901 disposed on the first slide 901. 02. The fourth linear module 902 is arranged along the height direction. The fourth linear module 902 can be a linear motor, which will not be described in detail here. The fourth linear module 902 drives the first mounting base 903 to rise and fall. The bottom of the first mounting base 903 is provided with a material picking bracket 904. The bottom of the material picking bracket 904 is provided with a plurality of vacuum nozzles 905. In a preferred embodiment, the shape and size of the material picking bracket 904 are consistent with those of the product, and four vacuum nozzles 905 are provided at the four corners of the material picking bracket 904 for adsorbing the four corners of the product. The number and position of the vacuum nozzles 905 can be adjusted according to actual needs, which will not be described in detail here.

[0029] like Figure 3 As shown, in some embodiments, a detection mechanism is also provided between the buffer rack 1 and the film-tearing mechanism 5. The detection mechanism includes a scanning camera 10 located on the top of the second linear module 7. The scanning camera 10 adopts an existing scanning camera product, which will not be described in detail here. When the film-tearing platform 3 moves the product between the buffer rack 1 and the film-tearing mechanism 5, it will pass the bottom of the scanning camera 10, thereby scanning and locating the film-tearing position of the product through the scanning camera 10. After each film tearing, the film-tearing platform 3 can also move back to the bottom of the scanning camera 10 to scan and detect the film-tearing status of the product again. If there is still release film that has not been torn off, it will return to the bottom of the film-tearing mechanism 5 to complete the film tearing.

[0030] like Figure 1 , Figure 2As shown, in some embodiments, the film-tearing mechanism 5 further includes a second slide 503 movably connected to the first linear module 6. A fifth linear module 504, arranged along the height direction, is mounted on the second slide 503. In one embodiment, the fifth linear module 504 can be a linear motor, driving a second mounting base 505 to rise and fall. The gripper 501 is located at the bottom of the second mounting base 505. In a preferred embodiment, multiple grippers 501 are provided at the bottom of the second mounting base 505. Each gripper 501 is a rotary gripper 501 capable of rotating around its own axis, allowing the grippers 501 to selectively tear off the release film according to different angles set by the release film, further improving the accuracy of the film-tearing operation. The rotary gripper 501 uses existing rotary gripper 501 products, such as the ERG series electric rotary gripper 501 produced by Suzhou Junduo Robotics Co., Ltd., or other existing gripper 501 products with rotational functions, which will not be elaborated upon here.
