PLC circuit board washing device and washing method

Abstract

The invention relates to the field of PLC circuit boards. The invention provides a PLC circuit board washing device. The device comprises a brush movement mechanism and an impurity recovery box. The brush movement mechanism and the impurity recovery box are both fixed to a workbench, the brush movement mechanism is connected with the upper end of the impurity recovery box, and the upper end of thebrush movement mechanism makes contact with a PLC circuit board. The impurity recovery box is used for receiving impurities after the PLC circuit board is cleaned; and the brush movement mechanism isused for cleaning the PLC circuit board. According to the device, by arranging the impurity recovery box, the slow cleaning process of the impurity recovery box is avoided, and the cleaning efficiency of the PLC circuit board is improved.

Description

technical field [0001] The invention relates to the field of PLC circuit boards, in particular to a PLC circuit board scrubbing device and a scrubbing method. 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 important ...

AI Technical Summary

Problems solved by technology

[0004] The prior art has the following deficiencies: 1. When washing the PLC circuit board, the impurities after washing fall into the square flat-bottomed impurity recovery box for recycling; and the flat-bottomed impurity recovery box does not have a collection and guiding effect on the impurities, and the impurities after washing will fall. Randomly scattered in various positions in the flat-bottomed impurity recovery box; when cleaning the impurities in the flat-bottomed impurity recovery box, the entire bottom surface of the flat-bottomed impurity recovery box needs to be cleaned, resulting in a slow cleaning process of the impurity recovery box and reducing the cleaning efficiency of the PLC circuit board

2. When the surface of the PLC circuit board is air-dried for the second time, it is only air-dried by rotating the PLC circuit board; when the PLC circuit board is only rotated, the PLC circuit board only moves in the horizontal direction; The cleaning agent between the components is blocked in the horizontal direction, and cannot flow out when the PLC circuit board moves horizontally, resulting in insufficient drying of the PLC circuit board when it is air-dried for the second time, affecting the cleaning quality of the PLC circuit board
