Circuit board cleaning device

Abstract

The utility model discloses a circuit board cleaning device, which relates to the field of circuit boards and comprises a chip groove, a first support, a second support, a conveying assembly, a hollow roller and a cleaning brush wheel, the first support and the second support are respectively arranged on two sides of the chip groove, and the first support is arranged obliquely above the second support. The conveying assemblies and the hollow roller are arranged between the first support and the second support in a staggered mode, the two ends of the hollow roller are rotationally arranged on the first support and the second support respectively, and a plurality of air outlet holes are formed in the outer circumferential face of the hollow roller along a spiral line. The first roller and the second roller are rotatably arranged on the first support and the second support respectively, and the cleaning brush wheels and the second roller are fixedly connected in a one-to-one correspondence mode. The circuit board is kept inclined during conveying, attachments on the surface of the circuit board are blown to the side edge of the lower end of the circuit board through high-pressure airflow, and the attachments on the side edge of the circuit board are brushed away through the cleaning brush wheel.
