The pasting of various protective films is complex in operation and labor-intensive, and the phenomenon of misalignment, deviation and multiple bubbles is common.

[0003] At present, the automatic film pasting equipment usually includes a film suction plate and a roll pressing film assembly. When pasting the film, the film suction plate needs to be controlled to be inclined at a certain angle with the horizontal plane, and then the roll pressing assembly is controlled to press down to roll and press the protective film, so as to realize the automatic pasting of the protective film. In the existing automatic film pasting equipment, the film suction plate is controlled to suck the protective film, the film suction plate is controlled to be inclined at a certain angle with the horizontal plane, and the roll pressing film assembly is controlled to move up and down.

The multi-axis driving mechanism or the multi-axis mechanical hand can realize automatic movement of the functional head, so as to realize automatic suction of the protective film and automatic pasting of the protective film on the product.

[0056] The working principle of the present application is as follows: when the film is pasted, the positive pressure gas reaches the positive pressure cavity 21 through the positive pressure gas path and generates positive pressure in the positive pressure cavity 21, thereby pushing the piston 22 to move against the elastic force of the return spring, and the piston 22 simultaneously drives the first piston rod 23 and the second piston rod 24 to move backward, the first driving end controls the film suction plate 41 to rotate around the first rotating shaft 43, so that the end of the film suction plate 41 away from the first rotating shaft 43 is inclined upward, and the second driving end pushes the abutting rod 53 to move backward, the abutting roller 55 at the lower end of the abutting rod 53 abuts against the abutting inclined surface 54, since the upper end of the connecting rod is movably connected with the fixed seat 20, when the abutting rod 53 moves backward, the abutting roller 55 moves backward along the abutting inclined surface 54 synchronously, under the action of the abutting roller 55, the connecting rod is displaced downward, thereby driving the rolling seat 51 and the pressure roller 52 to move downward and press on the upper surface of the protective film, at this time, the film pasting mechanism is controlled to move along the film pasting direction by an external driving mechanism, so that the protective film is pasted on the surface of the product, and the air bubbles are driven out by the rolling of the pressure roller 52, thereby improving the film pasting quality; when the film is sucked, the positive pressure gas stops working, the piston 22 moves forward under the action of the return spring, the piston 22 simultaneously drives the first piston rod 23 and the second piston rod 24 to move forward, the first driving end controls the film suction plate 41 to rotate around the first rotating shaft 43, so that the film suction plate 41 returns to the horizontal state, and the second driving end controls the rolling film pasting assembly 50 to move upward, so as to avoid the influence of the rolling film pasting assembly 50 on the normal suction of the film suction plate 41, when the horizontal angle of the film suction plate 41 is adjusted by the rotating driving assembly 30, the negative pressure gas passes through the negative pressure gas path to generate negative pressure in the negative pressure cavity 45, thereby causing the protective film to be adsorbed on the lower surface of the film suction plate 41 through the air suction hole 46.

[0057] In summary, the present application sets the negative pressure gas path front section and the positive pressure gas path front section on the connecting plate, sets the negative pressure gas path middle section and the positive pressure gas path middle section in the rotating driving assembly, sets the negative pressure gas path rear section and the positive pressure gas path rear section in the fixed seat, and sets the negative pressure gas path tail section and the negative pressure cavity in the film suction plate assembly, thereby forming the hidden negative pressure gas path and the positive pressure gas path inside the film pasting mechanism, reducing the use of pipelines, simplifying the gas path structure of the film pasting mechanism, avoiding the problems of pipeline bending, winding and breaking, improving the reliability of the equipment, and also reducing the overall volume of the equipment.
