A second transfer mechanism 340 is slidably connected to the longitudinal guide rail 330. The second transfer mechanism 340 is equipped with a negative pressure adsorption device for adsorbing and moving the PCB board. The inlet end of the third conveying component 320 is connected to the outlet end of the second conveying component 220. The outlet end of the third conveying component 320 is equipped with a stacking cart 400. The second transfer mechanism 340 is used to move the PCB board from the third conveying component 320 to the stacking cart 400. The third conveying component 320 includes supports hanging vertically on both sides, a conveying roller between the two supports, and a conveying motor below the conveying roller.

[0036] The processing method is as follows: When measuring the thickness of the sheet material, the stacking cart 400 is moved to the discharge end of the third conveying component 320. The support rod 352 of the lifting mechanism 350 is inserted between the roller brackets 430 to provide support for the stacking plate 500 above the rollers 440 and move the stacking plate 500 to a specific position. The sheet material to be tested enters the first conveying component 120. The controller detects the sheet material to be tested through sensors and controls the baffle below the crossbeam 130 to rise, blocking the sheet material to be tested. The control center positioning mechanism moves the sheet material to be tested to the center and controls the engraving mechanism to engrave on the sheet material. After the engraving is completed, the baffle descends, and the first conveying component 120 transfers the sheet material to the laser thickness measuring mechanism for thickness measurement. The laser thickness measuring mechanism sends the thickness measurement data to the controller. The controller determines whether the thickness of the sheet material is qualified according to the set threshold. When the detected sheet material thickness exceeds the threshold, it is determined to be unqualified. The unqualified sheet material enters the second conveying component 220, and the controller controls the first transfer mechanism 250 to move the unqualified sheet material to the sorting platform 230. When the thickness of the sheet material is within the threshold range, it is deemed qualified. The qualified sheet material passes through the second conveying component 220 and enters the third conveying component 320. It is then stacked on the stacking plate 500 via the second transfer mechanism 340. The thickness sensor 311 monitors the stacking thickness of the sheet material on the stacking plate 500 in real time and transmits the data to the controller. The controller controls the lifting mechanism 350 to move up and down, maintaining dynamic balance in the stacking position of the sheet material and ensuring stable operation of the second transfer mechanism 340. After the stacking plate 500 is completed, the lifting mechanism 350 places the stacking plate 500 on the roller 440, and the stacking cart 400 moves the sheet material that has undergone thickness measurement to the next process.
