Description

Technical Field

[0001] The invention belongs to the technical field of film tearing equipment, and in particular relates to an automatic film tearing equipment. Background Art

[0002] In the production process of flexible circuit boards, the front-end processes (such as pickling, etching, etc.) will be produced in the form of a whole plate, which can effectively save costs. In the front-end production process, in order to protect each small circuit board on the whole plate, a protective layer will be attached to the whole plate. After the flexible circuit board completes the front-end process, the protective layer of each small circuit board needs to be removed to expose the circuit board. First of all, the protective layer of each small circuit board will be laser cut according to the shape of the circuit board using laser equipment. If the protective layer is cut off directly, the circuit board will be damaged if the laser depth is not well controlled, and the cut waste cannot be effectively recycled.

[0003] In summary, when cutting the protective layer of a small circuit board, a small section of the micro-connection area will be reserved in the circumferential direction without cutting, and a small amount of laser cutting depth will be reserved in the depth direction. After the product is off the line, the operator manually uses tape to tear it off. Since manual film tearing is inefficient and manual workers directly contact the circuit board, it is very easy to cause the flexible circuit board to fail due to misoperation, resulting in product scrapping. Summary of the invention

[0015] As a further improvement of the present invention, at least one guide ring set is installed on the first driven roller.

[0016] The beneficial effects of the present invention are:

[0017] (1) The whole surface is pressed and the film is torn off. The moving mechanism moves at one time to complete the tearing of all protective films.

[0018] (2) The product to be torn off is lifted by the moving mechanism to come into contact with the tape, and the adhesive surface of the tape is wound outward on a rubber pressure roller. The pressure roller is slightly deformed by being squeezed by the moving mechanism, pressing the tape into the cover plate, and coming into contact with the product to be torn off under the cover plate to achieve adhesion. The mold spring is used to ensure a stable pressing force, thereby improving the film tearing quality.

[0019] (3) During the lamination process, the moving mechanism moves forward, and the tape is retracted and unwound by the rotation of two air shafts. At the same time, the guide plate is set up so that the direction of the force applied to the protective film of the product when it is pasted on the tape forms an angle with the movement direction of the moving mechanism, causing the protective film to separate from the product without damaging the product, thereby ensuring product quality during the production process and reducing costs.

[0020] (4) The protective film pasted on the tape will be rolled up together with the tape. The whole process is fully automated, which is convenient and fast and does not require waste collection. The waste roll only needs to be taken out when replacing the new tape.

[0021] (5) By adopting multiple rows of single-roll narrow tape, multiple rows can be operated simultaneously, which is used for products to be torn off with sparsely arranged protective films, thereby avoiding waste.

[0022] (6) A guide ring is provided on the first driven roller to guide the position of the adhesive tape to prevent a single adhesive tape from running off during operation and to further improve the film tearing quality. BRIEF DESCRIPTION OF THE DRAWINGS

The side end of the preferred support plate 110 of the present invention is installed with at least two limit blocks 112, which can limit the film product 18 to be torn. In the present invention, at least one second positioning pin 114 is preferably installed on the support plate 110, and the moving mechanism 14 drives the product 18 to be torn off to move to the bottom of the cover plate assembly 30. The cover plate assembly 30 presses the cover plate 32 onto the product through the lifting cylinder 38. The cover plate 32 is limited in the area surrounded by the four limit blocks 112, and the second positioning pin 114 passes through the cover plate 32.

The protective film 26 is separated from the product 18 to be torn off, and the film tearing is completed. At this time, the moving mechanism 14 moves to position 14A, and the protective film 26 and the adhesive tape 24 are rolled up on the winding shaft 132. At this time, the cover plate 32 is still covering the product 156 after the film is torn off. The cover plate 32 on the product 156 is not shown in the figure. The product 156 after the film is torn off is brought back from position 14A by the moving mechanism 14 and moved to the lifting assembly 31. The lifting cylinder 38 drives the support plate 40 to rise, and the first positioning pin 42 passes through the cover plate 32. The lifting assembly 31 receives the cover plate 32, and the moving mechanism 14 continues to drive the product 156 after the film is torn off to move, and the gripper mechanism 12 unloads the product 156 after the film is torn off onto the unloading platform 154.
