In the present embodiment, referring to fig. 8, the film pasting device 5 includes a film pasting device main body 51, a main body driving device 52, a film pressing mechanism 53 and a film taking mechanism 54, wherein the film sticking device main body 51 is movably arranged between the film separating device 7 and the positioning table component 3a, the main body driving device 52 drives the film sticking device main body 51 to move, the film pressing mechanism 53 comprises a film pressing piece 531 and a film pressing driving mechanism 532 which are arranged on the film sticking device main body 51, wherein, the film pressing piece 531 can be movably arranged up and down, the film pressing driving mechanism 532 drives the film pressing piece 531 to move up and down, the film taking mechanism 54 includes a pickup portion 541 and a pickup portion driving mechanism 542 mounted to the film sticking apparatus main body 51, the pick-up portion 541 is movable up and down and is configured to pick up a film, and the pick-up portion driving mechanism 542 drives the pick-up portion to move up and down.

Obviously, the specific structure of the film sticking device 5 is not limited to the above structure, for example, the film sticking device 5 may be only responsible for sticking a film and not for taking out a film, the film sticking device 5 only includes the film sticking mechanism 100, the film sticking device main body 51 does not need to be movably disposed between the film separating device 7 and the positioning table assembly 3a, and the film sticking device 5 needs the film pressing mechanism 53 capable of performing a film sticking action.

During film lamination, the film laminating device main body 51 moves to the position of the film separating device 7, the film at the position of the film separating device 7 is taken out through the film taking mechanism 54, then the film laminating device main body 51 moves to the positioning table assembly 3a (specifically, the positioning table assembly 3a at the film laminating station), and then the film laminating device main body 51 continues to move, so that the film pressing mechanism 53 is positioned at the positioning table assembly 3a, and film pressing is performed through the film pressing piece 531.

Further, in this embodiment, the film pressing member 531 includes a film attaching roller to attach the film to the PCB to be filmed by rolling the film attaching roller, so as to prevent bubbles and scratches.

Optionally, in this embodiment, the pickup portion 541 is rotatably connected to the pickup portion driving mechanism 542, and is mounted on the film sticking apparatus main body 51 through the pickup portion driving mechanism 542, a rotating shaft of the pickup portion 541 is horizontally arranged to be capable of rotating to a horizontal position and an inclined position inclined to the horizontal plane, and the film sticking apparatus 5 further includes a rotation driving device 543 provided on the film sticking apparatus main body 51 for driving the pickup portion 541 to rotate. When the film is taken, the rotary driving device 543 drives the picking portion 541 to a horizontal position so as to pick up the film on the positioning table component 3a, and when the film is pasted, the rotary driving device 543 drives the picking portion 541 to an inclined position so that one end of the film, which is close to the PCB board to be pasted with the film, is inclined downwards so as to be in contact with the PCB board to be pasted with the film.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
