[0027] The workpiece is placed on the surface of the top plate 101, and the fan 7 is started, causing the sealing box 6 and the connecting pipe 8 to generate negative pressure. Air enters the connecting groove 502 from the end of the connecting channel 504 away from the connecting groove 502, causing the connecting channel 504 to generate a continuous airflow. Since the connecting holes 503 and the connecting channels 504 are perpendicular to each other, each connecting hole 503 and the first through hole 101a generate negative pressure. The greater the flow rate of the connecting channel 504, the stronger the adsorption capacity of the first through hole 101a for the product. Even if a part of the first through hole 101a is not blocked by the workpiece, each first through hole 101a will still generate negative pressure. After the fan 7 stops, the connecting channel 504 is connected to the atmosphere, causing the first through hole 101a to return to normal pressure, and the workpiece can be removed.
