PLC circuit board cleaning method and device

Abstract

The invention relates to the field of PLC circuit boards. A PLC circuit board cleaning method comprises the following steps that (1) a PLC circuit board is conveyed through a circuit board conveying device; (2) the PLC circuit board is washed by a circuit board washing device; and (3) the PLC circuit board is obliquely overturned and air-dried through a circuit board overturning and air-drying device. According to the PLC circuit board cleaning method, by arranging the circuit board conveying device, the size of the whole conveying device is reduced, and the occupied space of equipment is reduced; by arranging the circuit board washing device, the slow cleaning process of an impurity recycling box is avoided, and the washing efficiency of the PLC circuit board is improved; and by arrangingthe circuit board overturning and air-drying device, the PLC circuit board is fully dried during secondary air-drying, and the cleaning quality of the PLC circuit board is ensured.

Description

technical field [0001] The invention relates to the field of PLC circuit boards, in particular to a cleaning method and cleaning equipment for a PLC circuit board. Background technique [0002] The PLC circuit board is the provider of the electrical connection of electronic components. The use of the PLC circuit board can greatly reduce the errors of wiring and assembly, and improve the level of automation and labor productivity. In the circuit board welding assembly, after the components on the PLC circuit board are installed through various welding processes, a certain amount of residue will remain on the component pins on the panel due to flux, solder and environmental influences. These residues directly affect the quality of the product, must be cleaned to ensure the electrical performance indicators of the PLC circuit board, and ultimately ensure the stability, reliability and working life of the electronic product, so the cleaning of the PLC circuit board is very impor...

Problems solved by technology

[0004] The prior art has the following deficiencies: 1. When conveying the PLC circuit board, the lever is first moved down to the side of the PLC circuit board, and then the moving device drives the lever to move so as to drive the PLC circuit board to move forward, and the PLC circuit board moves forward and then dials The lever is retracted vertically to avoid touching the PLC circuit board; and there are many electronic components on the PLC circuit board, when there are electronic components with a higher height on the PLC circuit board, the vertical retraction of the lever needs to be moved higher The height of the whole conveying device is larger, which increases the occupied space of the equipment.

2. When washing the PLC circuit board, the impurities after washing fall into the square flat-bottomed impurity recovery box for recycling; while the flat-bottomed impurity recovery box has no guiding effect on the collection of
