Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a four-sided film peeling device for display screen preparation. Background Art

[0002] POL (polarizer) is one of the core materials that make up LCD. It is an optical film that transmits light from the LCD backlight in a single direction and cuts off light in the other direction.

[0003] During the production process, there are many defects in the frame of CP repair products. Analysis shows that Pol appearance defects are more common at the frame position, and the warping defects are concentrated at the frame. Most of the defects are more obvious after the film is torn off, and the frame position obstructs the inspection;

[0004] Therefore, it is necessary to conduct a four-side film tearing inspection. However, the current four-side film tearing inspection in the factory area uses manual film tearing, and the inspection efficiency is low.

[0005] To this end, we propose a four-sided film peeling device for display screen preparation to solve the existing problems. Utility Model Content

[0012] The two slide bars are respectively provided with threaded holes adapted to the two ends of the screw rod, and the slide bars are threadedly engaged with the screw rod through the threaded holes;

[0013] The upper surface of the slide bar is in sliding contact with the lower surface of the rotating disk.

[0014] Preferably, a frame is mounted on the upper surface of the back plate;

[0015] A motor is installed on the upper surface of the frame, and the output end of the motor is connected to the middle axis end of the turntable.

[0016] Preferably, a support seat is provided on the lower surface of the workbench;

[0017] There are four support seats in total, and the positions of the four support seats are distributed in a rectangular array on the lower surface of the workbench.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] During the use of the four-sided film stripping device for display screen preparation of the utility model, during the display screen preparation and production process, the workpiece plate to be inspected can be placed squarely on the designated position of the working plate, and at this time, the external pump suction structure is connected through the air suction joint on the working plate, so that negative pressure is formed in the air duct, and the workpiece can be adsorbed and positioned on the working plate as a whole under the action of the negative pressure;

[0020] Then, the distance between the two slide bars is adjusted by rotating the screw rod, thereby controlling the vacuum suction cup to be at the side position of the workpiece;
