[0025] Preferably, the alignment component 3 includes a turntable 301 and two guide rods 303. The turntable 301 is installed on one side of the bracket 1. The output end of the turntable 301 is fixedly connected to a bidirectional screw rod 302. The middle part of the bidirectional screw rod 302 is threadedly sleeved with two limit sliders 305.

[0028] After the circuit board is transported to the position of the laminating assembly 8 by the conveying roller 2 and the alignment assembly 3, the upper and lower pressure rollers 804 begin to press the circuit board, driving the two pressure rollers 804 to rotate, wherein the lower pressure roller 804 is flush with the conveying roller 2, and the rotation of the pressure roller 804 drives the protective film 802 to coat the upper and lower surfaces of the circuit board, wherein the first film-collecting roller 803 tears the first outer film 805 and the protective film 802, and collects the first outer film 805, and the second film-collecting roller 807 is used to collect the second outer film 806 cut by the longitudinal cutting assembly 10, wherein there are multiple groups of pressure rollers 804, the pressure roller 804 on the front side is used to press and coat the circuit board, and the pressure roller 804 on the rear side is used to press the circuit board after coating, so as to fully fit the circuit board and the protective film 802 to avoid the generation of bubbles.

[0029] Preferably, the longitudinal cutting assembly 10 includes a first mounting plate 1001 and a second mounting plate 1002, a telescopic rod 1003 is fixedly connected between the first mounting plate 1001 and the second mounting plate 1002, the second mounting plate 1002 is fixedly connected to the bracket 1, the first mounting plate 1001 and the second mounting plate 1002 are both rotatably connected to two second rollers 1006 on one side close to the first outer film 805 through a rotating shaft, and the plurality of second rollers 1006 are rotatably connected to the protective film 802, a second cutting knife 1010 is slidably sleeved on the middle part of the second mounting plate 1002 through a slider, a fixed rod 1008 is rotatably sleeved on the side of the second cutting knife 1010 close to the protective film 802 through a limiting plate 1009, a third roller 1007 is fixedly connected to the side of the limiting plate 1009 away from the second cutting knife 1010, and the third roller 1007 is rotatably connected to the protective film 802; The middle part of the telescopic rod 1003 is clamped with the limiting sleeve 1005 through the third limiting rod 1011, a compression spring 1004 is provided between the telescopic rod 1003 and the limiting sleeve 1005, the limiting sleeve 1005 is provided with a plurality of limiting grooves 10051, the limiting grooves 10051 are clamped with the third limiting rod 1011, and the third limiting rod 1011 and the limiting sleeve 1005 adjust the tightness of the compression spring 1004 through the limiting grooves 10051; After the circuit board is coated on both sides by the coating assembly 8, the second rollers 1006 on the first mounting plate 1001 and the second mounting plate 1002 are in contact with the two sides of the circuit board.

The second cutting knife 1010 moves up and down for higher cutting efficiency and more even cutting surfaces. Since there are gaps between the circuit boards during transportation, When the second roller 1006 does not contact the circuit board, the compression spring 1004 drives the telescopic rod 1003 to retract. At this time, the second roller 1006 will be attached to the upper and lower sides of the protective film 802 and rotate, and then the protective film 802 is cut by the second cutting knife 1010 to avoid the protective film 802 from being uncut. When the second roller 1006 encounters the circuit board, the second roller 1006 drives the first mounting plate 1001 to move upward, drives the telescopic rod 1003 to extend, and stretches the compression spring 1004, which can effectively keep the second roller 1006 in contact with the protective film 802 on the outside of the circuit board.

There are multiple conveyor rollers 2, some of which are equipped with power components and can rotate independently. This technology is currently widely used in the field of conveying technology, so it will not be elaborated on. When the circuit board is transported on the conveyor roller 2, it is aligned and corrected by the alignment component 3, and enters the coating component 8 for coating. After the coating is completed, the horizontal cutting component 4 and the longitudinal cutting component 10 are used to perform precise cutting along the circuit board, and finally it is transported to the flip plate component 5 through the conveying component 6, so as to facilitate the observation of both sides of the circuit board to see whether there are bubbles and whether they need to be repaired, so as to avoid manually turning over each circuit board for inspection.

When the first roller 4024 on the right contacts the circuit board and the first roller 4024 on the left does not contact the circuit board, the circuit board on the left presses down the protective film 802 and sticks the protective film 802 to the side of the circuit board.
