Automobile lamp decoration ring sputtering aluminum plating system and process

Abstract

The invention relates to an automobile lamp decoration ring sputtering aluminum plating system and process. The automobile lamp decoration ring sputtering aluminum plating system comprises a vacuum chamber and a vacuum pump, an aluminum bar is vertically installed in the vacuum chamber, an aluminum target material is installed in the side wall of the vacuum chamber, and a shielding device is installed on the side wall of the vacuum chamber; one side of the vacuum chamber is communicated with a feeding pipe, a silicone oil electric valve is installed on the feeding pipe, and one side of the feeding pipe communicates with a heating device; one side of the vacuum chamber communicates with an argon inlet pipe, an argon electric valve is installed on the argon inlet pipe, and one end of the argon inlet pipe communicates with an argon source; a mounting device is mounted in the vacuum chamber, and the mounting device comprises a turntable and a first driving motor; the turntable is sleeved and fixed on an output shaft of the first driving motor; and a plurality of installation shafts are arranged on the rotary disc in the circumferential direction in an array mode, each installation shaft is vertically and rotationally connected to the rotary disc, a first driving mechanism used for driving the installation shafts to rotate is installed in the vacuum chamber, and clamps used for fixing workpieces are installed on the installation shafts. The anti-oxidation film can be conveniently plated on the outer surface of the aluminum mold.

Description

technical field [0001] The invention relates to the technical field of sputtering coating, in particular to a sputtering aluminum coating system and process for car lamp trims. Background technique [0002] The sputtering coating technology is to bombard the surface of the target with ions, and the phenomenon that the atoms of the target are knocked out is called sputtering. The deposition of atoms generated by sputtering on the surface of the substrate is called sputter coating. Usually, gas discharge is used to generate gas ionization, and its positive ions bombard the cathode target at high speed under the action of an electric field, knock out atoms or molecules of the cathode target, and fly to the surface of the substrate to be plated to form a thin film. [0003] The prior art can refer to the Chinese utility model patent whose authorized notification number is CN208577776U, which discloses a vacuum coating machine for high-voltage ion bombardment, including a vacuum...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: for driving safety, it is generally necessary to coat the outer surface of the car light trim with an aluminum film (the aluminum film has a reflective effect), and the aluminum mold may be oxidized, so it is necessary to coat the aluminum film on the outer surface of the aluminum film. The surface is coated with an anti-oxidation film, and the above-mentioned equipment is inconvenient to coat the outer surface of the aluminum mold with an anti-oxidation film
