The two sets of lifting screws 302 rotate synchronously through the sprocket B304 and the chain; so that the lifting seat 303 drives the guide frame 201 to move downward.

The double-headed screws B105 drive the two sets of drive seats C107 to move in opposite directions, so that the top limiting frames 501 of the drive seats C107 move synchronously; thus, the two sets of limiting plates 504 clamp and limit the longitudinal sides of the plates through the limiting rollers 505; then the drive motor A is started, and the drive motor A drives the drive seat A102 and the drive seat B103 to move in opposite directions through the double-headed screw A101, so that the top limiting frames 501 of the drive seat A102 and the drive seat B103 move synchronously, and thus the other two sets of limiting plates 504 clamp and limit the transverse sides of the plates through the limiting rollers 505; when the limiting rollers 505 apply a clamping force to the plates, the rubber block 507 applies a reaction force to the pressure sensor 506, and the pressure sensor 506 transmits the pressure signal to the control module 603. When the pressure value reaches the specified value, the control module 603 controls the drive motor A and the drive motor B to stop working; so that the limiting rollers 505 apply an appropriate fixing and limiting force to the circuit board; then the door body 604 is closed, and the two door bodies 604 are fixedly connected by the fixing component 7 and the fixing hook 605; then the auxiliary box 601 is evacuated to vacuum by the vacuum machine and the air extraction pipe 602; the top laminating frame 401 is driven to move downward by the hydraulic cylinder 1010, so that the top laminating frame 401 drives the other laminating frames 401 to move synchronously through the linkage rod A403, the linkage rod B404 and the fixed shaft 402, so that multiple laminating frames 401 can work simultaneously and carry out parallel lamination operations on multiple groups of circuit boards; the plates after being laminated by the laminating frame 401 form multi-layer circuit boards.
