To improve the cleaning efficiency, the number of throwing times of the device on the touch screen can be set, and the workpiece can be thrown up and down for cleaning (only up and down). The mechanical arm is provided with a basket pressing protection switch for clamping and grabbing, which has the function of preventing the basket from being pressed. The principle of ultrasonic physical cleaning is that the transducer converts the electrical energy provided by the generator into mechanical vibration of ultrasonic frequency (15000-68000 times per second), and radiates ultrasonic waves to the safety solvent in the ultrasonic cleaning tank through the stainless steel vibration plate, so as to strip the dirt on the surface of the workpiece, narrow slit, deep hole and micro-hole, and achieve deep cleaning effect.

[0027] The scattered and complex-shaped tooling to be cleaned is placed in a cleaning basket, and the tooling to be cleaned is transferred into a cleaning tank through an automatic conveying channel. Residual drug paste on the tooling is stripped and dispersed into the cleaning solvent through cavitation effects such as micro-jet, shock wave and the like in the cleaning solvent. In the ultrasonic cleaning step, the cleaning solvent in the cleaning device can be supplemented and added. The cleaned tooling can be transferred to a rinsing tank through an automatic conveying channel to rinse the tooling, remove a small amount of impurities attached to the surface of the tooling, and then transferred to a discharge station to complete the cleaning process.
