Abstract
The invention discloses a spraying device. The spraying device comprises a spraying unit, a dip angle unit, a rotating unit and a heating unit; a spraying process is characterized by comprising the following steps of placing components into a sealed roller, wherein the ratio of the volume of the component stack to the volume of the roller is 1:8 to 10; heating the bottom of the roller to be 95-105DEG C and then enabling the roller to perform rotation; providing an epoxy resin mixed solution, atomizing the epoxy resin mixed solution to spray into the roller by a spraying gun, wherein the distance between the spraying gun and the component is 80-120mm, and the spraying amount of the epoxy resin mixed solution is 1.5-5 ml / min; meanwhile, injecting hot air into the roller, wherein the temperature of the hot air is 75-85 DEG C, the pressure is not greater than 0.2MPa, and the gluing rate of the product is 5-10[mu]m / min; and after the spraying time is reached, completing spraying. By adoption of the method, thermal spraying can be realized, the spraying reliability, the controllability and the uniformity are strong, the oxidation resistance and salt mist corrosion resistance after beingsprayed are high, the spraying time is short, and the efficiency is high.
Description
technical field [0001] The invention relates to the field of surface spraying, in particular to a surface insulation spraying device and a spraying process for electronic components. Background technique [0002] With the continuous development of science and technology, the development of the electronic technology industry is advancing by leaps and bounds, so the demand for electronic components is also increasing. , when a failure occurs, it will have a great impact, so this type of product should have extremely high reliability. If it is used in an environment with corrosive gas and high humidity, the electronic product will quickly corrode, and its reliability and life will be reduced. shorten. Therefore, it is generally necessary to perform surface insulation protection on electronic components to improve the oxidation and corrosion resistance of the product. [0003] At present, the surface insulation spraying process is mainly used for the protection of electronic c...
