Description

Technical Field

[0001] This utility model relates to the field of film-tearing devices, specifically to a film-tearing mechanism. Background Technology

[0002] Before performing defect inspection on the panel, interference from the process film on the screen must be eliminated. The protective film must be removed before inspection. After the bare screen is inspected, it is covered with the original protective film again before leaving the equipment for the next process to protect the screen from scratches.

[0003] Traditional technology typically involves first removing the original protective film from the product using a conventional easy-tear film removal mechanism, then discarding the old film into a waste bin. After passing through an inspection station, a new protective film is applied at a roller laminating station. This current method consumes the same batch of protective film and auxiliary materials—easy-tear film. Furthermore, manual operation requires periodic cleaning of the removed old film and replacement of new protective film and easy-tear film. The overall process increases both material and labor costs. Additionally, the film removal and laminating processes require significant space, necessitating a large cleanroom environment.

The tear film detection mechanism 9 is installed on the connector 45 and is located above the first roller 53.

[0030] Working principle of a film-peeling mechanism:

[0031] Film removal stage:

[0032] A layer of adhesive board is pre-attached to the bottom of the tape 8. The Z-axis lifting mechanism 3 drives the mounting frame 2 to descend, so that the steel tape descends to a position about 1-2 mm from the product surface. The second roller 63 of the film-tearing part 6 moves to the film-tearing starting position under the drive of the horizontal moving component 4. At this time, the film-tearing part 6 and the corner-raising part 71 are located on the same side of the product. The second driving component 61 drives the second roller 63 to contact the product surface. The horizontal moving component 4 moves the second roller 63 horizontally a certain distance, so that the adhesive board adheres to the product protective film. The third driving component 711 of the corner-raising part 71 drives the third roller 713 to rise, so that the working area of ​​the tape 8 forms an angle with the product surface, lifting the edge of the protective film. The horizontal moving component 4 continues to drive the second roller 63 away from the third roller 713 of the corner-raising part 71. During the process of moving away, it continues to contact the product surface, so that the protective film is detached from the product surface. The Z-axis lifting mechanism 3 drives the mounting frame 2 to rise, and the third roller 713 resets, completing the film tearing. The film tearing detection mechanism 9 detects whether the protective film on the product surface has been torn off.

[0033] Lamination stage:

[0034] After the product passes the defect detection process, it moves to the working area of ​​the film-tearing mechanism. At this time, the film-tearing part 6 is at the end of the film-tearing position. The Z-axis lifting mechanism 3 drives the mounting frame 2 to descend, so that the working area of ​​the roll 8 is lowered to a position about 1~2mm away from the product surface. The first driving component 51 drives the first roller 53 to press down. The first roller 53 presses the protective film onto the product surface. At this time, the horizontal moving component 4 drives the first roller 53 to move towards the direction of the third roller 713, so that the protective film is reattached to the product surface.

[0035] The advantages of this utility model are: by using the film coating part 5, the film tearing part 6 and the corner lifting mechanism 7, a single device can use the same protective film in the film tearing and film coating process, which reduces the material consumption in the process, lowers the production cost of the process, reduces the manpower configuration in the product process, and is also conducive to the size of the compressor table and saves the area of ​​the cleanroom.

[0036] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present utility model, and all of these fall within the protection scope of the present utility model.
