[0002] Film is a film material, primarily composed of a protective film, an emulsion layer, a binder film, a base, and an anti-halation layer. During printed circuit board processing, a laminating machine is required to lay and laminate the film onto the printed circuit board. For example, Chinese patent application number CN202221442331.7 describes an automatic film laminating machine. This patent utilizes a designed extrusion roller in conjunction with a conveyor belt to achieve extrusion lamination between the film and the circuit board.

[0003] The existing laminating mechanism has certain shortcomings during use. Generally, the film and the circuit board are laminated first, and then leveled to remove bubbles. However, after the film and the circuit board are laminated, it is not convenient to remove the bubbles, and forced leveling will cause damage to the film. Therefore, it is necessary to design a new film laminating mechanism to solve this problem. Utility Model Content

[0006] Preferably, the two scrapers are in close contact with each other, and a rubber scraper strip is fixedly connected to the bottom end of the scraper.

[0007] Preferably, the screw rod is provided with two threads in opposite directions, and the two side plates are movably connected to the surface of the screw rod through the two threads.

[0008] Preferably, both side panels are slidably connected to the limiting rods, and there are two limiting rods, which are symmetrically distributed.

[0009] Preferably, a sliding assembly is provided between the side plate and the connecting plate, and the sliding assembly includes a sliding block fixed to the end of the connecting plate, and a sliding groove opened inside the side plate and slidably connected to the sliding block.

[0010] Preferably, the base includes a base body, a bottom plate movably mounted on the top surface of the base body, a mounting frame fixed on the top surface of the bottom plate, and side grooves opened on both sides of the mounting frame, and the circuit board is mounted inside the mounting frame.

[0011] Preferably, the base further includes a toggle bar, and the toggle bar is symmetrically fixed on the top surface of the bottom plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When laminating the film and the circuit board, the film can be placed between the two straps first, and then the oil pump is started to push the connecting plate and the scraper downward. The scraper is used to push the middle part of the film to bend it and fit it with the surface of the circuit board. Then the screw is turned to drive the side plate to move, so that the straps and the scraper are gradually separated. The scraper gradually pushes the film from the middle to the sides and spreads it on the surface of the circuit board to complete the lamination between the two. In the process of gradually spreading the film, the bubbles will be pushed out from both sides by the scraper. The advantage of this design is that it can complete the lamination of the film and the removal of bubbles at the same time, without damaging the film, and can quickly and effectively remove bubbles.
