The wind shear flow rate of the blowing device in the invention is preferably 100 +/-1 KM/H.

The jig used in cleaning can be of various feasible structures, such as a basket for conventional ultrasonic cleaning, or other containers with water leakage and holding space.

The following briefly describes a cleaning method of an ultrasonic cleaning machine:

and S1, placing the jig 100 with the workpiece on the two first support rails 21 and between the push rods 12.

S2, the motor 10 is started to drive the two chains to rotate to drive the push rod 12 to rotate, and to push the fixture 100 on the first support rail 21 to move toward the second support rail 22.

And S3, moving the jig 100 to the second support rail 22 in the second state, stopping the motor 10, and stopping the rotation of the chain 21.

S4, retracting the cylinder shaft of the second lifting cylinder 221 to lower the two second support rails 22, and simultaneously driving the jig 100 to descend into the cleaning tank of the ultrasonic cleaning machine for ultrasonic cleaning.

S5, after the ultrasonic cleaning is completed, the cylinder shaft of the second lifting cylinder 221 extends to drive the second support rail 22 and the jig 100 to ascend until the second support rail 22 returns to the second state and is engaged with the first support rail and the third support rail.

And S6, the motor 10 is started to drive the chain 21 to rotate again, and the push rod 22 pushes the jig 10 to the third support rail 23 and moves to the tail end for blanking.

Further, besides ultrasonic cleaning, the method can also perform other cleaning processes according to different requirements, for example, before ultrasonic cleaning, the workpiece on the first support rail can be subjected to high-pressure water cleaning through the second cleaning mechanism; after the ultrasonic cleaning, the workpiece on the third support rail may be subjected to low-pressure water washing by the first cleaning mechanism.
