Description

Technical Field

[0001] This application relates to the field of FPC manufacturing, and more particularly to a protective membrane separation device. 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 to solve the technical problem that the traditional method of manually tearing apart the protective film and release paper results in low work efficiency and is prone to damaging the protective film.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a protective film separation device, the protective film separation device including: a support plate, and an external gripper to place the incoming film on the support plate;

[0006] The roll assembly includes a first roll roller and a first lifting cylinder, wherein the first lifting cylinder drives the first roll roller to contact the protective film.

[0007] The adsorption plate has several adsorption holes;

[0008] The translation component includes a slide rail motor. The roll assembly is connected to the slide rail motor. Driven by the slide rail motor, the first roll roller shaft moves laterally. During the lateral movement of the first roll roller shaft, the first roll roller shaft rotates due to friction, causing a portion of the protective film to be wound up on the first roll roller shaft. Then, the slide rail motor drives the first roll roller shaft to move axially to the adsorption hole, causing the adsorption hole to adsorb and fix the protective film on the first roll roller shaft. The first roll roller shaft continues to move until the protective film is detached from the first roll roller shaft.

[0009] The release paper separation assembly includes a second roll shaft and a first clamping roll shaft. The release paper falls onto the second roll shaft, and the first clamping roll shaft and the second roll shaft clamp and fix the release paper. The second roll shaft separates the release paper from the protective film by rotating.

[0010] Optionally, the protective film separation device further includes a first conveying roller and a second conveying roller, the first conveying roller and the second conveying roller being disposed on the side of the support plate away from the adsorption plate, the conveying roller being used to convey the incoming film falling on the support plate to the roll assembly.

[0011] Optionally, the separator paper separation assembly further includes a second clamping roller and a first rotary motor. Before the first clamping roller clamps the separator paper, the second clamping roller and the second roll roller clamp and fix the separator paper. The first rotary motor drives the second roll roller to make an arc-shaped movement in space, so that the end of the separator paper fixed by the second clamping roller moves to below the support plate.

[0012] Optionally, the separator paper separation assembly further includes a separation cylinder for pushing the second clamping roller shaft away from the second roll roller shaft.

[0013] Optionally, the roll assembly further includes a first dust removal roller shaft and a second lifting cylinder. The second lifting cylinder is connected to the first dust removal roller shaft and is used to drive the first dust removal roller shaft to move along the first roll shaft, so that the first dust removal roller shaft abuts against the first roll shaft, so as to remove dust from the first roll shaft.

[0014] Optionally, the protective film separation device 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.

[0015] Optionally, the first roll shaft has adhesive properties to facilitate fixing the protective film to the first roll shaft.

[0016] 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.

[0017] Optionally, the protective film separation device further includes a film-paper separation component, which includes a pressure plate and a toothed groove. The toothed groove is provided with a plurality of first toothed bars, the pressure plate is located directly above the toothed groove, and the side of the pressure plate near the toothed groove is provided with a plurality of second toothed bars. When the protective film and the release paper are difficult to separate, the incoming film needs to be pre-separated by the film-paper separation component.

[0018] The beneficial effects of this application are as follows: In the protective film separation device provided by this application, the lateral movement of the first roll roller shaft causes a portion of the protective film to be wound on the first roll roller shaft. Then, the adsorption hole adsorbs and fixes the protective film on the first roll roller shaft. The first clamping roller shaft and the second roll roller shaft clamp and fix the release paper. The second roll roller shaft rotates to completely separate the release paper from the protective film, thereby solving 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 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.

[0044] 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 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.

[0049] 201 is parallel, the first dust removal roller shaft 210 is fixedly assembled with the fourth fixed plate 207, and the second lifting cylinder 206 can drive the first dust removal roller shaft 210 to move vertically, so that the first dust removal roller shaft 210 abuts against the first roll material roller shaft 201, so as to remove the dust from the first roll material roller shaft 201.

[0050] The adsorption plate 300 is elongated and located on the side of the support plate 100 away from the tooth groove 101. The adsorption plate 300 is horizontally positioned and has several adsorption holes arranged in a matrix. The adsorption plate 300 is connected to an external air pump, which enables the adsorption plate 300 to adsorb and fix the protective film from the adsorption holes.

[0051] In summary, after a portion of the protective film is wound around the first roll shaft 201, the slide rail motor 112 drives the first roll shaft 201 to move toward the adsorption plate 300, so that the adsorption plate 300 adsorbs and fixes the protective film.

A third assembly plate is provided at the output end of each of the two first clamping cylinders 508. The two third assembly plates are arranged in parallel and spaced apart. The third assembly plates are fixedly assembled with the first clamping cylinders 508.

[0056] A first clamping roller 502 is provided between the two third assembly plates. The first clamping roller 502 is arranged laterally and is parallel to and spaced apart from the second roll roller 501. The first clamping roller 502 is rotatably connected to the two third assembly plates. The first clamping cylinder 508 can drive the first clamping roller 502 to move toward the second roll roller 501 so that the first clamping roller 502 and the second roll roller 501 can clamp and fix the release paper.

[0057] The second clamping roller shaft 503 is located on the side of the second winding roller shaft 501, and is arranged parallel to and spaced apart from the second winding roller shaft 501.

Two separation cylinders 505 are provided, and the two separation cylinders 505 are respectively located at the two fixing blocks. The separation cylinders 505 are arranged horizontally, and the output end of the separation cylinders 505 faces the fixing block. The separation cylinders 505 can push the second clamping roller shaft 503 away from the second winding roller shaft 501 through the fixing block.

[0060] 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.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
