Circuit board cleaning device for electrical instrument and instrument production

Abstract

The invention discloses a circuit board cleaning device for electrical instrument and instrument production. The circuit board cleaning device comprises a cleaning box, a conveying cleaning mechanism, a plurality of positioning row assemblies, a circuit board body, a recycling screening structure and two guide assemblies. The conveying and cleaning mechanism comprises four driving guide rollers symmetrically and fixedly installed on the front position and the rear position of the upper surface of the cleaning box, four first tensioning rollers symmetrically and rotationally installed on the two sides of the inner wall of the cleaning box, four second tensioning rollers symmetrically and rotationally installed on the two sides of the inner wall of the cleaning box, and a conveying belt. Each positioning row assembly comprises four stand columns and four insertion rods. The recycling and screening structure comprises a recycling box, a rubber covered edge, an inner edge, a layered screening plate, four jacking air cylinders and four ground plates. The circuit board cleaning device for electrical instrument and instrument production can be suitable for the cleaning treatment procedure of circuit boards machined in batches, and the cleaning efficiency is high; and by providing a rapid screening structure for solid-liquid layering of impurities in the cleaning liquid, the convenience of recycling and reusing the cleaning liquid can be improved.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a circuit board cleaning device for the production of electrical instruments. Background technique [0002] The circuit board is an important component on the meter instrument, which may be called a printed circuit board or printed circuit board. The circuit board is mainly composed of pads, vias, mounting holes, wires, components, connectors, filling, electrical boundaries, etc. In the production process of the circuit board, in order to ensure the safety of the circuit board, the surface of the circuit board needs to be smooth, and the circuit board needs to be cleaned after production. [0003] According to the application announcement number CN110935687A a circuit board cleaning device for instrumentation production, it improves the cleaning effect of the circuit board by means of ultrasonic generator vibration cleaning, and the cleaning effect is remarkable, but ...

Problems solved by technology

[0004] Based on this, it is necessary to aim at the current circuit board cleaning device for instrumentation production, which improves the cleaning effect of the circuit board through the vibration cleaning of the ultrasonic generator, and the cleaning effect is remarkable, but the cleaning method has relatively large limitations and is aimed at batch production. The processed circuit board cannot be used for cleaning, and the cleaning efficiency is low; in addition, after the circuit board is cleaned by the existing circuit board cleaning device for instrumentation production, there are more floc impurities in the used cleaning solution, because the existing The cleaning device does not have a rapid screening structure for effectively realizing the solid-liquid stratification of impurities in the cleaning liquid, which affects the convenience of recycling and reuse of the cleaning liquid. A cleaning device for circuit boards used in the production of electrical instruments is provided
