Plasma cleaning equipment in two-sided turnover door structure

Abstract

The invention discloses plasma cleaning equipment in a two-sided turnover door structure. The plasma cleaning equipment comprises a vacuum system, a door, a vacuum chamber body, a hinge, a rack component, a high-pressure lead-in component, a support, a polar plate, a hinge fixing plate, a hinge shaft, a hinge plate, a positioning device, a rotary shaft, a handle and a computer control system, wherein the vacuum system has the main characteristics that the plasma cleaning equipment consists of a roots pump (main pump), a screw pump (backing pump) and a roughing valve; the door has the main characteristics that the door consists of a flat plate, and a lamp rack component is arranged on the flat plate; the vacuum chamber body has the main characteristics that the vacuum chamber body consists of a shell; a sealing ring, an air suction opening, an observation window, an atmosphere point measurement point, an air charging system, a gauge tube port and an air entraining device; and the air entraining device comprises a precise gas mass flowmeter. The plasma cleaning equipment has the advantages that compared with a lamp processed by the traditional equipment, the film-matrix binding force and the reflective rate after the lamp processed by the plasma cleaning equipment is subjected to vacuum coating can be improved greatly. Compared with the traditional equipment, the plasma cleaning equipment is simple in structure, smaller in occupied area, shorter in production cycle and higher in efficiency.

Description

technical field [0001] The invention relates to a vacuum plasma cleaning device used before the surface metallization treatment of automobile lamps and plastic decorative parts, in particular to a plasma cleaning device with a double-sided reversing door structure. Background technique [0002] At present, the reflectors of automobile lamps are generally sprayed with primer after injection molding and then coated, or some unprimed lamps are directly coated, and the bonding force between the coating layer and the substrate or the film layer and the substrate is very poor. After such a lamp is used for a long time, the film layer will fall off, yellow, and bubbles will occur. Such lamps can only be used in the low-end market, which restricts the development of my country's automobile industry to a large extent. [0003] In recent years, the global automobile industry has begun to develop rapidly, the amount of automotive lamps has increased sharply, and the requirements for p...
