The seal washing device is started by electrifying, the cleaning liquid supply mechanism 32 injects a proper amount of cleaning liquid into the cell body 311 of the ultrasonic cleaning cell 31, and the heater heats the cleaning liquid in the cell body 311 to 40 ℃.

Then, the elevating mechanism 21 drives the stamp holder 22 to move downward from the initial position in the vertical direction until the stamp 10 enters the cleaning liquid in the cell body 311 and the stamp face of the stamp 10 is located below the liquid level of the cleaning liquid, and locks the position of the stamp holder 22. After the stamp 10 is soaked in the cleaning solution for 1min, the ultrasonic generator is started to perform ultrasonic cleaning on the stamp 10.

Next, after the ultrasonic cleaning is completed, the elevating mechanism 21 drives the stamp holder 22 to move upward and return to the initial position of the stamp holder 22 in the vertical direction.

Then, the second driving element 411 in the translation mechanism 41 drives the sliding element 412 to slide on the sliding rail 413, so that the reducing roller brush 422 moves from the initial position in the horizontal direction to the lower side of the stamp 10, and the reducing roller brush 422 abuts against the stamp surface of the stamp 10.

After the seal 10 is cleaned, the reducing rolling brush 422 stops rotating, the second driving element 411 drives the reducing rolling brush 422 to be separated from the seal 10 and to press against the seal, and drives the sliding element 412 to return to the initial position in the horizontal direction, and the seal cleaning device finishes the seal 10 cleaning operation.

And finally, manually taking out the seal 10, and wiping off a small amount of cleaning solution remained on the seal 10.

It should be noted that before the stamp 10 is ultrasonically cleaned, the cleaning solution in the cell body 311 is heated first, and then the stamp 10 is soaked in the cleaning solution for a preset time. Specifically, the cleaning liquid is heated to a preset temperature by using a heater, and the preset temperature of the cleaning liquid is 40 ℃. The seal 10 is immersed in the cleaning solution for a preset time of 1min, and then an ultrasonic generator is started to perform ultrasonic cleaning on the seal 10. By immersing the stamp 10 in the preheated cleaning liquid, the cleaning efficiency of the stamp washing device is improved.
