[0022] The circuit board can be conveyed to the bottom of the three frames 4 by the conveyor belt 3, and the reinforcing steel sheet can be placed in the storage frame 6 on the three frames 4, so that the threaded rod 14 can be driven to rotate by the servo motor 5 on the frame 4, and the transmission block on the threaded rod 14 can be moved axially along the threaded rod 14 through the screw-in relationship, thereby driving the negative pressure suction head 12 connected to the bottom of the electric cylinder 10 to move axially. When the negative pressure suction head 12 moves to the top of the storage frame 6, the telescopic rod 11 can be driven to extend and retract by the electric cylinder 10, thereby making the negative pressure suction head 12 vertically move. It moves straight downward and absorbs and grabs the reinforcing steel sheets in the storage frame 6. After grabbing, the negative pressure suction head 12 can be driven vertically upward by the electric cylinder 10, and the threaded rod 14 can be driven to rotate in the opposite direction by the servo motor 5, so that the transmission slider 9 drives the negative pressure suction head 12 to move horizontally to just above the circuit board, and the negative pressure suction head 12 is driven vertically downward by the electric cylinder 10 to complete the attachment of the reinforcing steel sheets. Through the three sets of frames 4, reinforcing steel sheets of different sizes and models can be attached at the same time, without the need for frequent manual replacement of reinforcing steel sheets, which greatly improves work efficiency.

[0025] Specifically, in this embodiment, a guide rod 13 is arranged in the sliding groove 18 , and a sliding hole matched with the guide rod 13 is formed on the plug-in block 16 .

[0026] By the mutual cooperation of the arranged guide rod 13 and the sliding hole, the moving direction of the plug-in block 16 can be guided, so that the moving process of the plug-in block 16 is more stable.

[0027] Specifically, in this embodiment, a return spring 19 is sleeved on the guide rod 13 , one end of the return spring 19 is mounted on the inner wall of the sliding groove 18 , and the other end of the return spring 19 is mounted on the plug-in block 16 .
