[0025] It can be understood that, referring to Figures 1 to 3 , a circuit board laminating machine of the present utility model includes a frame 100, a lamination mechanism 200, a conveying mechanism 300, and an unwinding mechanism 400. The lamination mechanism 200 includes two first driving members 210 and two hot pressing rollers 220. The two hot pressing rollers 220 are arranged vertically opposite to each other, and a gap is formed between the two hot pressing rollers 220. The hot pressing rollers 220 are rotatably connected to the frame 100. The first driving members 210 correspond to the hot pressing rollers 220 one by one, and the first driving members 210 are used to drive the hot pressing rollers 220 to rotate; the conveying mechanism 300 includes a second driving member 310 and multiple conveying rollers 320. The multiple conveying rollers 320 are arranged horizontally and parallel to each other. The conveying rollers 320 are rotatably connected to the frame 100. The second driving member 310 is used to drive the conveying rollers 320 to rotate to convey the circuit board to the hot pressing rollers 220; the unwinding mechanism 400 includes two third driving members 410 and two unwinding rollers 420. The unwinding rollers 420 correspond to the hot pressing rollers 220 one by one, and the third driving members 410 correspond to the unwinding rollers 420 one by one. The third driving members 410 are used to drive the unwinding rollers 420 to rotate so that the unwinding rollers 420 convey the film to the hot pressing rollers 220.

[0026] Place the circuit board on the conveying rollers 320, drive the conveying rollers 320 to rotate through the second driving member 310 to convey the circuit board to the hot pressing rollers 220, so that the circuit board passes through the gap between the two hot pressing rollers 220. At the same time, drive the unwinding rollers 420 to rotate through the third driving member 410 so that the unwinding rollers 420 convey the film to the hot pressing rollers 220. Since the unwinding rollers 420 correspond to the hot pressing rollers 220 one by one, the film can be conveyed to the two hot pressing rollers 220 respectively, and drive the hot pressing rollers 220 to rotate through the first driving member 210. The two vertically opposite hot pressing rollers 220 are used to press the films on both sides onto the two side plates of the circuit board respectively, thereby improving the laminating efficiency and reducing the manual labor intensity.

[0027] It should be noted that the first driving member 210, the second driving member 310, and the third driving member 410 can all be servo motors or stepping motors, etc., as long as they can drive the hot pressing rollers 220, the conveying rollers 320, and the unwinding rollers 420 to rotate.

[0028] The conveying rollers 320 are divided into two groups. The two groups of conveying rollers 320 are respectively arranged on the opposite sides of the hot pressing rollers 220. One group of conveying rollers 320 is used to convey the circuit board to the hot pressing rollers 220, and the other group is used to output the circuit board after lamination.

[0029] A cutting mechanism can be arranged on the discharging side of the hot pressing roller 220 for cutting the film after film pressing to achieve continuous film pressing processing.

[0030] It can be understood that, referring to Figure 1 and Figure 2 , along the conveying direction of the conveying mechanism 300, two guiding strips 330 are arranged on the feeding side of the hot pressing roller 220. The two guiding strips 330 are symmetrically arranged on the frame 100, and the circuit board can pass between the two guiding strips 330. Since along the conveying direction of the conveying mechanism 300, two guiding strips 330 are arranged on the feeding side of the hot pressing roller 220, and the two guiding strips 330 are symmetrically arranged on the frame 100, when the conveying roller 320 drives the circuit board to move and pass between the two guiding strips 330, by using the two guiding strips 330 to respectively abut against the opposite sides of the circuit board, the circuit board can be guided and limited, so as to reduce the horizontal position offset of the circuit board, thereby improving the stability of the circuit board conveying.

[0031] It should be noted that during the process of the conveying roller 320 driving the circuit board to move, a horizontal position offset will occur, causing the circuit board to tilt when passing through the gap between the two hot pressing rollers 220. As a result, when the film is attached to the board surface, a relative position offset will occur between the circuit board and the film, further affecting the film pressing quality. By guiding and limiting through the guiding strip 330, the position offset of the circuit board can be reduced to improve the film pressing quality.

[0032] Specifically, referring to Figure 1 and Figure 2 , a guiding inclined surface 331 is arranged at one end of the guiding strip 330 away from the hot pressing roller 220. The guiding inclined surfaces 331 of the two guiding strips 330 face each other, and the distance between the two guiding inclined surfaces 331 gradually decreases along the conveying direction of the conveying mechanism 300. Since the guiding inclined surfaces 331 of the two guiding strips 330 face each other, and the distance between the two guiding inclined surfaces 331 gradually decreases along the conveying direction of the conveying mechanism 300, by gradually guiding the circuit board to be centered and enter the gap between the two hot pressing rollers 220 through the guiding inclined surface 331, the stability of the circuit board conveying can be improved, thereby improving the film pressing quality.

[0033] Specifically, referring to Figure 1 and Figure 2, along the conveying direction of the conveying mechanism 300, two guiding wheels 340 are arranged on the discharging side of the hot pressing roller 220. The two guiding wheels 340 are symmetrically arranged on the frame 100, and the circuit board can pass between the two guiding wheels 340. Since two guiding wheels 340 are arranged on the discharging side of the hot pressing roller 220 along the conveying direction of the conveying mechanism 300, and the two guiding wheels 340 are symmetrically arranged on the frame 100, when the circuit board can pass between the two guiding wheels 340, by using the two guiding wheels 340 to respectively abut against the opposite sides of the circuit board, the circuit board can be guided and limited, so as to reduce the horizontal position deviation of the circuit board. Cooperating with the guiding and limiting of the guiding strip 330, the stability of the circuit board conveying can be further improved, so as to improve the film pressing quality.

[0034] It should be noted that the axial direction of the guiding wheel 340 is vertically arranged. By abutting the side wall of the guiding wheel 340 against the circuit board, when the circuit board moves, the guiding wheel 340 can be driven to rotate, which can reduce the wear of the circuit board.

[0035] Specifically, referring to Figure 1 and Figure 2 , along the conveying direction of the conveying mechanism 300, two pressing wheels 350 are arranged on the discharging side of the hot pressing roller 220. The two pressing wheels 350 are symmetrically arranged on the frame 100. The pressing wheels 350 are arranged axially parallel to the conveying roller 320, and the pressing wheels 350 can abut against the upper surface of the circuit board. Since the two pressing wheels 350 are symmetrically arranged on the frame 100, by abutting the upper surface of the circuit board with the pressing wheels 350 to press the circuit board tightly, the possibility of the circuit board warping upward can be reduced, so as to improve the stability of film pressing. And by pressing the film warped at the edge of the circuit board with the pressing wheels 350, the edge of the circuit board can be subjected to secondary film pressing. In addition, since the pressing wheels 350 are arranged axially parallel to the conveying roller 320, when the circuit board moves, the pressing wheels 350 can be driven to rotate, which can reduce the wear of the circuit board.

[0036] It can be understood that referring to Figures 1 to 3, the lamination mechanism 200 further includes an adjustment component 230. The adjustment component 230 includes a fixed seat 231, a screw 232, and two sliders 233. The fixed seat 231 is fixedly connected to the frame 100. The slider 233 is slidably connected to the fixed seat 231. The screw 232 is rotatably connected to the fixed seat 231. The hot pressing rollers 220 correspond to the sliders 233 one by one. One end of the hot pressing roller 220 is rotatably connected to the slider 233. Both sliders 233 are threadedly connected to the screw 232, and the thread directions of the two sliders 233 are opposite. When the screw 232 is rotated, the two sliders 233 can move closer to or away from each other vertically. Since the hot pressing rollers 220 correspond to the sliders 233 one by one, one end of the hot pressing roller 220 is rotatably connected to the slider 233. Both sliders 233 are threadedly connected to the screw 232, and the thread directions of the two sliders 233 are opposite. By rotating the screw 232, the two sliders 233 can move closer to or away from each other vertically and drive the two hot pressing rollers 220 to move, so as to adjust the distance between the two hot pressing rollers 220 to adapt to the film pressing treatment of circuit boards and films of different thicknesses, thereby improving the applicability of the circuit board film pressing machine.

[0037] Specifically, referring to Figures 1 to 3 , the fixed seat 231 is provided with a chute 234. The chute 234 is arranged vertically. The slider 233 is slidably connected to the chute 234. By guiding the vertical movement of the slider 233 through the chute 234, the stability of the movement of the slider 233 can be improved, thereby improving the stability of the adjustment of the distance between the two hot pressing rollers 220.

[0038] Specifically, referring to Figures 1 to 3 , a handle 235 is provided at one end of the screw 232 away from the slider 233. By providing a handle 235 at one end of the screw 232 away from the slider 233, it is convenient for the operator to apply force to rotate the screw 232, so as to improve the convenience of adjustment.

[0039] Specifically, referring to Figure 2 , there are two groups of adjustment components 230, and the two groups of adjustment components 230 are symmetrically arranged on the frame 100. By symmetrically arranging the two groups of adjustment components 230 to respectively adjust and limit the two ends of the hot pressing roller 220, the reliability of the position adjustment of the hot pressing roller 220 can be improved.

[0040] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
