Description

Technical Field

[0001] This application relates to the field of FPC manufacturing, and in particular to a protective film separation device that combines edge tearing and corner tearing. Background Technology

[0002] FPC stands for Flexible Printed Circuit Board, also known as Flexible Board or Flexible Circuit Board. It is a special type of printed circuit board characterized by its light weight, thinness, flexibility, and bendability. Compared to traditional rigid printed circuit boards (PCBs), FPCs offer higher wiring density and greater flexibility. FPCs are commonly used in electronic products that require movement or bending, such as smartphones, laptops, and digital cameras.

[0003] During the manufacturing process of FPC, a protective film needs to be covered on the side of the FPC with printed circuits to prevent the printed circuits from being worn. Generally, the protective film is pasted on a layer of release paper to prevent the protective film from being contaminated. Before attaching the protective film to the FPC, the protective film and the release paper need to be separated. The traditional method is to manually tear the protective film and the release paper apart. This production method is not only too inefficient, but also easily damages the protective film. Summary of the Invention

[0004] This application provides a protective film separation device that combines edge tearing and corner tearing to solve the technical problem that the traditional method of manually tearing the protective film and release paper results in low work efficiency and is prone to damaging the protective film.

[0009] The adsorption plate has several adsorption holes;

[0010] The translation component includes a first slide rail motor. The winding component is connected to the first slide rail motor. Driven by the first slide rail motor, the first winding roller shaft moves laterally. During the lateral movement of the first winding roller shaft, the first winding roller shaft rotates due to friction, causing a portion of the protective film to be wound up on the first winding roller shaft. Then, the first slide rail motor drives the first winding roller shaft to move axially to the adsorption hole, causing the adsorption hole to adsorb and fix the protective film on the first winding roller shaft. The first winding roller shaft continues to move until the protective film is detached from the first winding roller shaft.

[0011] The release paper separation assembly includes a second roll roller and a first clamping roller. The release paper falls onto the second roll roller, and the first clamping roller and the second roll roller clamp and fix the release paper. The second roll roller completely separates the release paper from the protective film by rotating.

[0019] Optionally, the protective film separation device combining edge tearing and corner tearing further includes a second dust removal roller and a guide plate. The guide plate is provided with a guide groove, which is inclined from the vertical direction toward the first conveying roller. The second dust removal roller is disposed in the guide groove, and the second dust removal roller is in contact with the first conveying roller along the guide groove due to gravity, so as to remove dust from the first conveying roller.

[0020] Optionally, the first roll shaft has adhesive properties to facilitate fixing the protective film to the first roll shaft.

[0021] Optionally, the roll assembly further includes a stop cylinder, the end of which is provided with a stop block. The stop cylinder can drive the stop block to move toward the first roll shaft, thereby stopping the first roll shaft from rotating.

[0023] Optionally, the corner tearing module further includes a material pulling assembly, which includes a clamping plate for clamping the incoming film on the carrier plate and pulling it into the corner tearing module.

[0024] The beneficial effects of this application are: In the protective film separation device that combines edge tearing and corner tearing provided in this application, different protective film separation methods are selected for different incoming films, which solves the technical problem that the traditional method of manually tearing the protective film and the release paper results in low work efficiency and easy damage to the protective film.

The second assembly plates 208 are vertically arranged and fixedly assembled with the third fixed plate 204. The first roll roller shaft 201 is located between the two second assembly plates 208. The first roll roller shaft 201 is cylindrical and horizontally arranged. The two ends of the first roll roller shaft 201 are fixedly connected to the second assembly plates 208. The surface of the first roll roller shaft 201 is adhesive.

[0058] In summary, the first lifting cylinder 202 can drive the first roll shaft 201 to move vertically, so that the first roll shaft 201 can come into contact with the incoming film on the support plate 100. Then, the first slide rail motor 112 drives the first roll shaft 201 to translate towards the tooth groove 101. While the first roll shaft 201 is translating towards the tooth groove 101, the first roll shaft 201 rotates under the action of friction.

[0071] In summary, before the first clamping roller 502 clamps the release paper, the second clamping cylinder 509 drives the second clamping roller 503 to clamp and fix the release paper. Then, the first rotary motor 504 drives the rotating seat 506 and the second winding roller 501 to rotate. Since the relative position of the second clamping roller 503 and the second winding roller 501 remains unchanged, the second clamping roller 503 will simultaneously make an arc-shaped movement in space, causing a portion of the release paper to be clamped by the second winding roller 501 and the second winding roller 502. The second clamping roller 503 is pulled to the bottom of the support plate 100. Then, the separating cylinder 505 drives the second clamping roller 503 away from the second roll roller 501. The first clamping cylinder 508 drives the first clamping roller 502 to move towards the second roll roller 501, fixing the release paper again. Finally, the third rotary motor 507 drives the second roll roller 501 to rotate, and through friction, the release paper is completely separated from the protective film, and the release paper is discharged to the bottom of the support plate 100.

[0072] The edge tearing module 1 is also equipped with a transfer component 700, which includes a transfer cylinder 710, a suction head fixing plate 720 and a transfer suction head 730.

[0073] The transfer cylinder 710 is vertically arranged and fixedly assembled with the third fixed plate. The output end of the transfer cylinder 710 passes through the third fixed plate. A suction head fixing plate 720 is provided at the output end of the transfer cylinder 710. The suction head fixing plate 720 is parallel to the third fixed plate and is fixedly assembled with the output end of the transfer cylinder 710. Several transfer suction heads 730 are provided and are evenly distributed on the suction head fixing plate 720. The transfer suction heads 730 are fixedly assembled with the suction head fixing plate 720, and the transfer suction heads 730 are connected to an external air pump so that the transfer suction heads 730 can adsorb and fix the incoming film.

[0074] In actual operation, when the edge tearing module 1 fails to work properly or the type of incoming film is not suitable for the edge tearing module 1, the operator will start the corner tearing module 2. At this time, the external gripper places the incoming film on the carrier plate, and the transfer cylinder 710 drives the transfer suction head 730 to adsorb and fix the incoming film. Under the drive of the first slide rail motor, the transfer suction head 730 sends the incoming film to the side of the carrier plate near the corner tearing module 2.

[0075] The corner tearing module 2 also includes a material pulling assembly 810, which is used to clamp the incoming film on the transfer suction head 730 and pull it toward the corner tearing module 2.

The material pulling cylinder 813 can drive the first clamping plate 812 and the second clamping plate 812 to clamp each other. There are two material pulling guide rails 811, which are arranged parallel and spaced apart. The two support plates are slidably assembled with the two material pulling guide rails 811. The material pulling motor 814 is connected to the support plate through a transmission belt and can drive the support plate to move along the material pulling guide rails 811.

[0077] In actual operation, the material pulling motor 814 drives the clamping plate 812 to move towards the edge tearing module 1. After the material pulling cylinder 813 drives the first clamping plate 812 and the second clamping plate 812 to clamp and fix the material film, the material pulling motor 814 then drives the clamping plate 812 to move away from the edge tearing module 1, so as to feed the material film into the corner tearing module 2.

[0078] The corner tearing module 2 also includes a corner tearing fixing plate 820, which is roughly rectangular and horizontally positioned between two material pulling guide rails 811. Several air holes are provided on the corner tearing fixing plate 820, and an air pump is connected to the air holes so that the corner tearing fixing plate 820 can adsorb and fix the incoming film in the material pulling assembly 810 through the air holes.

[0079] The corner tearing module 2 also includes a bonding head assembly 830, which includes a second slide rail motor 831, a bonding plate 832, an angle adjustment motor 833, a fixing seat 834, a mounting plate, and a lifting motor 835.

[0080] The bonding plate 832 is roughly rectangular and horizontally positioned. Several air holes are provided on the lower surface of the bonding plate 832, and an air pump is connected to the air holes. The bonding plate 832 can adsorb and fix the incoming film through the air holes. The fixing seat 834 is located above the bonding plate 832. The angle adjustment motor 833 is fixedly assembled with the fixing seat 834. The angle adjustment motor 833 is vertically positioned, and its output end is fixedly assembled with the bonding plate 832. The angle adjustment motor 833 can drive the bonding plate 832 to rotate.

[0081] The lifting motor 835 is vertically positioned, and its output end is connected to the fixed base 834, enabling the lifting motor 835 to drive the bonding plate 832 to move vertically. The second slide rail motor 831 is horizontally positioned, and the mounting plate is vertically positioned. The angle adjustment motor 833 is fixedly assembled with the mounting plate, and the mounting plate is slidably assembled with the second slide rail motor 831, enabling the second slide rail motor 831 to drive the bonding plate 832 to move laterally.

[0082] The corner tearing module 2 also includes a roller assembly 840, which includes a roller cylinder 841, a fixing frame 842, and a corner tearing roller 843. The roller cylinder 841 is horizontally positioned on the side of the bonding plate 832 away from the corner tearing fixing plate 820, and is located at one corner of the bonding plate 832. The roller cylinder 841 is fixedly assembled with the bonding plate 832. The fixing frame 842 is U-shaped and vertically positioned, and is fixedly assembled with the output end of the roller cylinder 841. The corner tearing roller 843 is cylindrical, has adhesive properties, is horizontally positioned, and is rotatably assembled with the fixing frame 842.

[0083] In summary, after the corner-tear fixing plate 820 adsorbs and fixes the incoming film, the lifting motor 835 drives the bonding plate 832 to move towards the corner-tear fixing plate 820 until the bonding plate 832 contacts the incoming film. The roller cylinder 841 then drives the corner-tear roller 843 to reciprocate at one corner of the incoming film, causing the corner-tear roller 843 to separate one corner of the protective film from the release film and adhere that corner. Afterwards, the bonding plate 832 adsorbs and fixes the entire incoming film. The angle adjustment motor 833 drives the bonding plate 832 to rotate, causing the corner-tear roller 843 to face the gripper assembly 850, and the second slide rail motor 831 drives the bonding plate 832 to move towards the gripper assembly 850.

[0084] The corner tearing module 2 also includes a gripper assembly 850, which includes a gripper guide rail 851, a gripper motor 852, a gripper, a gripper fixing plate 853, a gripper cylinder 854, and a gripper drive motor 855.

[0085] The gripper guide rail 851 is arranged horizontally, and a gripper fixing plate 853 is provided on the gripper guide rail 851. The gripper fixing plate 853 is slidably assembled with the gripper guide rail 851. The gripper motor 852 is arranged horizontally, and a transmission belt is provided at the output end of the gripper motor 852. The transmission belt is connected to the gripper fixing plate 853, so that the gripper motor 852 can drive the gripper fixing plate 853 to move horizontally along the gripper guide rail 851. A gripper cylinder 854 is also provided on the gripper fixing plate 853. The gripper cylinder 854 is fixedly assembled with the gripper fixing plate 853. The gripper is arranged horizontally, and the gripper is fixedly assembled with the output end of the gripper cylinder 854, so that the gripper cylinder 854 can drive the gripper to clamp and fix the release paper.

[0086] A gripper drive motor 855 is also provided on the gripper fixing plate 853. The gripper drive motor 855 is fixedly assembled with the gripper fixing plate 853. The gripper drive motor 855 is connected to the gripper cylinder 854. The gripper drive motor 855 can drive the gripper cylinder 854 to rotate, thereby driving the gripper to rotate.

[0087] In summary, after the angle adjustment motor 833 drives the bonding plate 832 to rotate, causing the corner tear roller 843 to face the gripper assembly 850, and the second slide rail motor 831 drives the bonding plate 832 to move towards the gripper assembly 850, the gripper cylinder 854 drives the gripper to clamp and fix the release paper at one corner where the release paper and protective film are separated. Then, the gripper drive motor 855 drives the gripper to rotate, causing the release paper to wrap around the gripper. Afterward, the gripper motor 852 drives the gripper to move laterally along the gripper guide rail 851, completely separating the release paper from the protective film.
