The mechanical arm (31) is matched with the first clamping module (32) to put the internal releasing unit (4) into the workpiece, the first clamping module (32) is used for releasing the clamping state of the internal releasing unit (4), the door opening component (6) is used for locking the workpiece cabinet door again after closing, and the controller (7) remotely controls the sub-control module (45) to start through the network module (47);
the first air pump (49) pumps the detection gas stored in the gas storage bottle (48) into the gas discharge module (410), and the gas discharge module (410) releases the detection gas in the gas storage bottle into the inner cavity of the workpiece;
Step eight, first motors (512) on the left side and the right side drive screw rods in the screw rod assemblies (511) at corresponding positions to rotate, so that screw rod nuts in the screw rod assemblies (511) drive a frame (513) to move up and down on the outer side of a workpiece;
Step nine, the air inlet head (514) sucks and discharges the outer side of the workpiece into the air capturing sensor (515), the air capturing sensor (515) sends detected air data into the controller (7), and the controller (7) detects the leakage degree and the leakage position of the workpiece according to an internal algorithm so as to obtain the tightness test data of the workpiece;
and step ten, after the detection is finished, the door opening component (6) opens a workpiece cabinet door, the mechanical arm (31) clamps the workpiece inside release unit (4) under the cooperation of the first clamping module (32) and then takes out the workpiece, the air filtering equipment (10) filters and discharges the gas inside the detection mechanism shell (21), and the first electric door (23) is opened to enable a worker to take out the workpiece after the surface detection of the roller disc (58) is finished.
