Description

Technical Field:

[0001] The utility model relates to a film tearing and pasting mechanism. Background Art:

[0002] From the perspective of the COB process, if high reliability and high display quality are to be achieved for COB products, the film laminating line, one of the back-end packaging processes of the COB module, is an important link. Most of the existing film laminating processes are off-line operations. After the operator tears off the bottom release film of the film sheet, the film sheet is placed on the lamp board, and then it is put into a vacuum degassing box to remove the bubbles between the film sheet and the lamp board. Manual operation has low efficiency, high production instability, and the operator will be fatigued after long-term operation, posing potential safety hazards. Content of the Utility Model:

Among them, the base is fixed to the machine table, the jaw lifting cylinder is fixed to the base, and the jaws, the film clamping platform, and the bottom film clamping cylinder are installed at the movable end of the jaw lifting cylinder to lift up and down integrally.

When the vacuum solenoid valve 24 is energized, compressed air passes through the vacuum solenoid valve 24 to the vacuum generator 23 and is quickly discharged from the muffler of the vacuum generator 23, thereby creating a pressure difference to drive the air in the channel to be discharged. The adsorption plate 28 cooperates with the film sheet on the machine table 1 to adsorb the film sheet onto the adsorption plate 28.

[0022] The displacement mechanism 4 includes a base body 41, an X-axis linear module 42, and a Y-axis linear module 43 that cooperate with each other.

The adsorption plate sucks 1 PCS of product (film), and is moved to the position above the film tearing mechanism through the X-axis linear module and the Y-axis linear module (displacement mechanism); the film tearing mechanism operates: the bottom film clamping cylinder retracts, and the grippers fit with the film clamping platform to clamp a corner of the bottom film. At this time, the film adsorption mechanism slowly moves to start tearing the film. After the film tearing is completed, the film adsorption mechanism is driven by the displacement mechanism to move to the film sticking position for the film to be attached to the lamp board; after the film is torn, the bottom film remains in the grippers and the film clamping platform; the bottom film clamping mechanism operates: the lifting cylinder rises, the bottom film clamping cylinder closes, and the bottom film grippers clamp the bottom film. At this time, the film tearing mechanism operates again: the bottom film clamping cylinder extends, the grippers and the film clamping platform release the bottom film.

The rotary cylinder rotates 90° in the opposite direction to wait for the next bottom film; at the same time, the film tearing mechanism operates again: the gripper lifting cylinder rises to wait for the next film.

[0027] When the bottom film full material sensor triggers a signal, it warns the operator to clean the bottom film in the bottom film recycling box body. Manually pull out the bottom film recycling box body along the drawer slide rail, open the movable door, close the movable door after cleaning, and push the bottom film recycling box body back to the working position.

[0028] The film tearing and sticking device provided by the present utility model can realize the full-automatic film tearing and sticking of the film, improve the production efficiency and automation degree; the bottom film recycling box can accommodate a large number of bottom films, reduce the manual cleaning frequency, reduce the manual work intensity, provide help for realizing full-automatic operation, optimize the manual function, reduce the manual fatigue degree, and improve the production efficiency and product yield.
