Abstract

The invention provides a non-contact cleaning device for surfaces of PCBs, and relates to the technical field of PCB testing and processing. The device comprises a No.1 assembly line rack and a No.2 assembly line rack arranged on the side edge of the No.1 assembly line rack in parallel, wherein the top end face of the No.1 assembly line rack is a horizontal plane, the middle of the top end of the No.1 assembly line rack is of a hollow structure, No.1 conveying belts are symmetrically arranged on the front side and the rear side of the top end of the No.1 assembly line rack, a supporting plate is placed at the top end of the No.1 assembly line rack, and a plurality of PCBs are arranged at the top end of the supporting plate at equal intervals in a matrix mode. According to the non-contact cleaning device for the surfaces of the PCBs, the PCBs can be effectively prevented from floating when a blowing device I and a blowing device II blow typhoon to the surfaces of the PCBs, and dust blown out by the blowing device I and the blowing device II enters an explosion-proof filtering system through an air suction pipeline. The explosion-proof filtering system filters the dust cleaned from the PCBs, so that the toxicity of the dust adsorbed on the surfaces of the PCBs is reduced. The non-contact cleaning of the PCBs is realized.

Description

technical field [0001] The invention relates to the technical field of PCB board testing and processing, in particular to a non-contact cleaning device for the surface of a PCB board. Background technique [0002] In the process of using the PCB board production line, it is necessary to perform a programming program on the PCB board to verify whether the produced PCB can be used normally. In the existing process of testing the PCB board, it is necessary to test the PCB board at different equipment stations. For program processing, if it is necessary to clean and remove the dust on the surface of the PCB board first, then install the PCB board on the pallet for testing. Therefore, during the testing process of the PCB board, it is necessary to switch between the PCB boards at different equipment stations location, this process takes up the time efficiency of the production line body. [0003] At present, in the process of cleaning and dedusting the surface of PCB boards, in ...
