Automatic cleaning equipment for circuit boards

The invention is applicable to the technical field of printed circuit boards, and provides automatic cleaning equipment for circuit boards, which comprises a supporting part obliquely arranged based on a horizontal plane and a material box assembly arranged on the supporting part in a reciprocating motion manner. The material box assembly comprises a material box for accommodating a circuit board. An electromagnet used for magnetically adsorbing the material box and a control switch assembly used for controlling the electromagnet to be powered on and powered off so as to enable the electromagnet to be magnetic or not are arranged on one side of the material box. The supporting part is further provided with a first photoelectric proximity switch used for detecting the material box and an air blowing device used for blowing the circuit board in the material box. The air blowing device can fully blow and sweep the circuit board in the material box to rapidly clean waste and dust on the circuit board. In the whol
