Abstract

The invention provides an electrostatic spraying method of a shell of an outdoor unit of an air conditioner. The method includes the steps of checking incoming material, to be specific, checking the appearance of the shell entering a powder house, and cleaning the powder house to keep it clean; checking a powder supply system and a recovery system in the powder house and a spray gun unit to make sure all devices run well; moving the shell into a painting room in the powder house, and spraying the shell; before spraying, cleaning accumulated powder in the spray gun unit and the powder supply system with dry compressed air to make sure that the powder is evenly atomized, and allowing a worker to adjust distances from different workpieces to the spray gun unit; checking the sprayed shell for discharging, and detecting a coating every 20 min with a thickness meter. The method has the advantages that high production cost of workpieces caused by misoperation is effectively reduced, productivity is effectively guaranteed by providing regular check steps, the method is simple to operate, and spraying effect of the shell of the outdoor unit of the air conditioner is evidently improved.

Description

technical field [0001] The invention relates to the field of spraying, in particular to an electrostatic spraying method for an air conditioner outer machine casing. Background technique [0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. The equipment consists of a spray gun, a spray cup, and an electrostatic spraying high-voltage power supply. Electrostatic spraying technology has been gradually applied to the outer shell of air conditioners. At present, the effect of electrostatic spraying in most air conditioner factories is not very satisfactory. Therefore, it is particularly important to solve this kind of problems. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an electrostatic spraying met...
