Detailed Implementation
[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] A high-speed copper-clad laminate laminating machine, such as Figure 1 and Figure 2 As shown, the system includes a mounting platform 1, a transport assembly 2 mounted on the right side of the mounting platform 1, the transport assembly 2 including a drive motor and transport rollers, the drive motor mounted on the front right side of the mounting platform 1, the output shaft of the drive motor connected to the transport rollers, and several transport rollers rotatably connected to the mounting platform 1, a film press 3 mounted on the left side of the mounting platform 1, a conveyor platform 4 connected to the right side of the mounting platform 1, a transport assembly 5 mounted on the conveyor platform 4, the transport assembly 5 including a drive motor 51, a pulley assembly 52 mounted on the output shaft of the drive motor 51, first transport rollers 53 connected to both the left and right sides of the pulley assembly 52, each of the first transport rollers 53 having anti-slip grooves, each of the first transport rollers 53 being rotatably connected to the conveyor platform 4, three second transport rollers 54 rotatably connected between the front and rear sides of the middle of the conveyor platform 4, a heater 6 mounted on the conveyor platform 4, the heater 6 having a detachable connection structure, the heater 6 being located above the first transport rollers 53 and the second transport rollers 54, and adjustment mechanisms 7 being provided at both the front and rear sides of the first transport rollers 53.
[0021] like Figures 1-3 As shown, the adjustment mechanism 7 includes an adjustment ring 71. Two adjustment rings 71 are slidably connected to the first conveying roller 53. Each adjustment ring 71 is slidably connected to a latch 72. Each latch 72 has a circular assisting component connected to its upper part. Each latch 72 is connected to an adjacent adjustment ring 71 by a spring 73.
[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a cleaning mechanism 8, which includes a mounting base 81. The mounting base 81 is connected to the rear right side of the mounting platform 1. A servo motor 82 is mounted on the mounting base 81, and a brush roller 83 is connected to the output shaft of the servo motor 82.
[0023] It should be noted that PCB boards are crucial components in electronic devices used to connect and support electronic components. PCB boards form circuit networks by laying conductive paths on an insulating substrate, thereby enabling electrical connections between electronic components. During PCB production, a high-speed laminator 3 tightly bonds copper foil to the substrate, forming a high-quality copper-clad laminate. During lamination, the substrate is first placed on the conveyor table 4, and then the drive motor 51 is started. The output shaft of the drive motor 51 rotates, driving the pulley assembly 52 to rotate, causing the first conveyor roller 53 and the second conveyor roller 54 to rotate, thus moving the substrate to the left. Simultaneously, the heater 6 is activated, intensifying the surface molecular activity of the substrate before lamination, increasing the intermolecular interaction force, which is beneficial for improving the adhesion strength between the copper foil and the substrate. Then, the heated substrate is continuously conveyed to the left by the transport assembly 2 until it reaches the lower part of the laminator 3, where it undergoes the lamination operation. However, when the substrate is placed on the conveyor table 4, the substrate and copper foil may not be centered and aligned, causing a positional deviation that affects the lamination process. To achieve the desired film effect, the adjusting mechanism 7 can be used for centering alignment. First, push the latch 72 upwards to compress the spring 73, simultaneously disengaging the adjusting ring 71 from the locking state of the first conveyor roller 53. Then, according to the substrate specifications, slide the adjusting ring 71 to the appropriate position, and then reset the latch 72. This resets the adjacent spring 73, causing the adjusting ring 71 to re-lock with the adjacent first conveyor roller 53. When placing the substrate onto the first conveyor roller 53, position it between two adjacent first adjusting rings 71, thereby centering the substrate and the copper film. Center alignment is beneficial for improving the lamination effect. During the PCB production process, there may be debris remaining on the substrate surface. If the debris and other impurities are directly applied to the copper lamination machine during lamination, they will embed into the substrate and affect the performance of the PCB. During transportation, the substrate surface needs to be cleaned to prevent debris and other impurities from being carried into the lamination machine 3 for lamination. The servo motor 82 is started, and the output shaft of the servo motor 82 rotates, driving the brush roller 83 to rotate, thereby sweeping away the debris remaining on the substrate surface so that the lamination operation can proceed smoothly.

These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
