In the process of operation, when the board is sent (taken out), the board matching robot 210 moves to the position corresponding to the first conveying component 260 at the front side of the base 222, after the first conveying component 260 receives a board taking instruction sent by the board matching robot 210, the telescopic piece 2712 drives the clamping block 2713 to move downwards from the retracted position to the open position, and then the board matching robot 210 pushes the PCB board to be processed in the material box 211 between the clamping block body 27132 and the fixed seat 2711. When receiving (material receiving), the board matching robot 210 moves to the position corresponding to the second conveying assembly 270 at the front side of the base 222, and receives the processed PCB boards below the material taking position on the second buffer stage 2222 into the bin 211.
