the first positioning sensor senses the PCB, the PLC controls the second air cylinder to start, a piston rod of the second air cylinder extends out, the positioning piece is pushed to rotate downwards along the guide groove and fall into the opening of the track cover plate, and the movement of the PCB is blocked;
fifthly, the second positioning sensor senses the PCB, the PLC controls the stepping motor to stop, and the PCB stops at the clamping station;
sixthly, the PLC controller controls the first cylinder to be started, the driven block is pushed to move forwards, the transverse sliding plate is driven to move forwards in a transverse mode, the shaft rod slides in the obliquely arranged waist-shaped hole, the jacking clamping plate is driven to ascend, and the jacking clamping plate is matched with the clamping sheet to clamp and fix the PCB;
after the PCB is machined, the PLC controls the first air cylinder to reset to drive the driven block to move backwards, the transverse sliding plate to move backwards, the shaft rod slides in the obliquely arranged waist-shaped hole to drive the jacking clamping plate to descend, and the PCB is loosened;
and the PLC controller controls the second cylinder to reset, pulls the positioning piece to rotate upwards along the guide groove, and exits from the opening;
the self-supporting PLC controls the stepping motor to start, drives the conveying belt to rotate, and conveys the PCB to the next procedure;
after the discharging inductor induces the PCB to leave the automatic clamping plate device, the new PCB is conveyed to enter the device in the previous process.
10. The automatic clamp plate apparatus of claim 9, wherein said step of adjusting further includes adjusting a distance between the two rail assemblies using a width adjustment handle.
