[0049] Next, the detection cylinder 301 works to drive the pressure block 303 at the bottom of the pressure sensor 302 to fit tightly with the PC board body 2, and the impact force of the PC board body 2 is detected by the pressure sensor 302 to realize the pressure detection operation of the PC board body 2. When the pressure detection result of the PC board body 2 meets the standard, the guide wheel 201 rotates to drive the PC board body 2 on the positioning base 1 to be transferred to the unloading conveyor belt 6, thereby realizing the automatic unloading operation of the PC board body 2. Finally, when the pressure detection result of the PC board body 2 does not meet the standard, the vacuum suction cup 711 works to attract the unqualified PC board body 2 with the bottom end of the vacuum suction cup 711, and the servo motor 701 works to drive the threaded slider 703 to slide along the inner wall of the limiting slide groove 704 through the screw rod 702, and the sliding of the threaded slider 703 drives the sliding beam 705 to slide horizontally, and the sliding of the sliding beam 705 drives the lifting column 706 to slide synchronously. At the same time, the sliding beam 705 slides through the lifting column 706 to drive the lifting guide block 708 at one end of the lifting beam 707 to slide along the inner wall of the transfer slide groove 709, and slides along the inner wall of the transfer slide groove 709 through the lifting guide block 708, thereby driving the lifting column 706 to slide vertically along the inner wall of the sliding beam 705, and the sliding of the lifting column 706 drives the vacuum suction cup 711 at the bottom end of the bracket 710 to move synchronously, and the unqualified PC board body 2 at the top of the positioning base 1 is transferred to the waste box 8, so as to realize the unqualified PC board body 2 unloading operation.
