Device for continuously performing primer spraying, drying and electroplating in vacuum chamber

Abstract

The invention discloses a device for continuously performing primer spraying, drying and electroplating in a vacuum chamber. The device comprises the vacuum chamber (1) and a vacuum pump (2) connected with the vacuum chamber (1), wherein the inside of the vacuum chamber (1) is provided with an electroplating platform (3) and a rotational stand (5); and the electroplating platform (3) is provided with two rows of electroplating electrodes (4). The device is characterized in that the inside of the vacuum chamber (1) is provided with at least one nozzle (6); the nozzle (6) is connected with a paint supply system through a pipe, and the paint supply system is outside the vacuum chamber (1); and the electroplating platform (3) is provided with at least one dryer (7). By adopting the device, the primer spraying, drying, film coating, finish spraying and drying processes of the traditional technology can be completed in the vacuum chamber, the processes, auxiliary equipment and site can be reduced and the cost can be lowered; and the device is good for the health of workers and the problem of environmental pollution can be eliminated.

Description

technical field [0001] The invention relates to a device in the vacuum electroplating industry, in particular to a device for continuously spraying primer, drying and electroplating in a vacuum chamber. Background technique [0002] Vacuum coating technology is an important branch of vacuum application technology. It has been widely used in optics, electronics, energy development, physical and chemical instruments, construction machinery, packaging, civilian products, surface science and scientific research. The methods used in vacuum coating mainly include evaporation plating. Sputtering plating, ion plating, beam deposition plating and molecular beam epitaxy, etc., in addition to chemical vapor deposition. Vacuum coating on plastic products has only been developed in recent years, and the development speed is very fast. It has become a large application field of vacuum coating. Vacuum coating of plastic products can be coated with aluminum, copper and other metals, and ca...

AI Technical Summary

Problems solved by technology

The traditional process has many procedures, long production cycle, high labor cost, and the paint contains toxic components, and the volatile gas is flammable and explosive, which not only poses safety hazards, damages the health of workers, but also pollutes the environment. The thickness of the film is uneven, which affects the quality of the product; the vacuum coating equipment produced by CREAVAC company in Germany is currently the most advanced equipment in the world. Evaporate the topcoat and block the vacuum pump and the vacuum chamber at the same time. After the topcoat is applied, the paint has cured and has no effect on the vacuum pump. However, the vacuum coating equipment produced by CREAVAC still does not place the process of spraying the primer in the vacuum chamber. Finished, still need manual spray primer
