Abstract

The invention discloses a vacuum pump, which can solve the problem that the conventional product is likely to stick dust on surface when entering the vacuum pump and to generate black spots during film plating and the problem that the adhesion force of a plated film is unstable. The vacuum pump comprises a vacuum enclosure, an evaporating electrode, an evaporating current controller, an ion generator and an ion generation controller, wherein the evaporating electrode is arranged in the vacuum enclosure; the evaporating electrode is also connected with the evaporating current controller outside the vacuum enclosure; the ion generator is arranged in the vacuum enclosure; and the ion generator is connected with the ion generation controller outside the vacuum enclosure. The vacuum pump has the advantage that ionic wind is generated by the ion generator under a vacuum condition to blow off dust on the surface of the product, eliminate the black spots and improve rate of finished product and the adhesion force of the plating of the product.

Description

technical field [0001] The invention relates to a vacuum machine. Background technique [0002] After the product is sprayed with primer, the product needs to be put into a vacuum machine to evacuate. After reaching the vacuum, the metal plating material evaporates and the metal is evenly plated on the surface of the product. However, when the product enters the vacuum machine, dust in the air will stick to the surface of the product during transportation, and black spots will form on the surface of the product after coating, resulting in a decrease in the yield rate. Moreover, after coating, the adhesion of the coating is unstable and easy fall off. Contents of the invention [0003] The purpose of the present invention is to provide a vacuum machine, which can effectively solve the problems that the surface of existing products is easily contaminated with dust when entering the vacuum machine, black spots are generated during coating, and the adhesion of the coating is ...
