So that the cleaning cleanliness of the first cleaning head will be higher than the cleaning proximity of the second cleaning head.

The sewage discharged through the first cleaning nozzle 41 is collected in the collecting tank 40, and is discharged into the sewage tank 92 through the second drain filter line communicating with the second drain port of the collecting tank 40. The second drainage filtering pipeline comprises a second drainage pipe 401 connected with a second drainage outlet at the bottom of the storage tank, a second filter screen 96 is arranged at the water outlet end of the second drainage pipe 401, and the second filter screen 96 can be fixed at the water outlet end of the second drainage pipe 401 or in a water tank on the sewage tank.

The air-cutting drying mechanism 5 is connected with an air blowing device (not shown in the figure), and the air blowing device may be a blower, a fan, or other devices disclosed in the prior art, and the structure thereof is not described herein. The gas is delivered to the drying nozzle 51 through the blowing device and is outputted to remove moisture from the surface of the workpiece. The air-cutting flow rate of the air 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 containing space.

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

s1, placing the jig 100 with the workpieces on the two first support rails 21 and between the push rods 12.

S2, the motor 10 starts to drive the two chains to rotate so as to drive the push rod 12 to rotate and push the jig 100 on the first support rail 21 to move towards the second support rail 22.

And S3, the jig 100 moves to the second support rail 22 in the second state, the motor 10 stops, and the chain 21 stops rotating.

S4, the cylinder shafts of the second lifting cylinders 221 retract to enable the two second support rails 22 to descend, and simultaneously drive the jig 100 to descend into a cleaning tank of the ultrasonic cleaner for ultrasonic cleaning.

And S5, after ultrasonic cleaning is finished, the cylinder shaft of the second lifting cylinder 221 stretches out to drive the second support rail 22 and the jig 100 to ascend until the second support rail 22 is restored to a second state to be connected with the first support rail and the third support rail.

S6, the motor 10 starts to drive the chain 21 to resume rotation, and the push rod 22 pushes the jig 100 to the third support rail 23 and moves to the tail end for discharging.

Furthermore, in addition to ultrasonic cleaning, other cleaning processes can be performed according to different requirements, for example, the workpiece on the first support rail can be subjected to high-pressure water cleaning by the second cleaning mechanism before ultrasonic cleaning; after ultrasonic cleaning, the workpiece on the third support rail can also be subjected to low-pressure water cleaning by the first cleaning mechanism. After the low-pressure water washing, the workpiece can be subjected to air cutting, air drying treatment and the like through an air cutting mechanism and a cleaning mechanism.

The invention has various embodiments, and all technical schemes formed by equivalent transformation or equivalent transformation fall within the protection scope of the invention.
