Description
Technical field
The present invention relates to automobile lamp components production technical fields, more particularly to a kind of automobile lamp adornment frame vacuum
Coating process.
Background technique
It is often coated with aluminum membranous layer on the parts such as the adornment frame on automobile lamp, the beauty of lamps and lanterns is improved by aluminum membranous layer, it is existing
Some aluminum membranous layers due in technique there are problem, the defects of coating sagging, also have hair it is color and under ultraviolet light irradiation xanthochromia
Wretched insufficiency.By the restriction of environment purification, the protective film of spraying plating often will cause particle, influence the beauty of lamps and lanterns.It aluminizes
Membrane process does not adapt to the increasingly developed quality requirement higher and higher to automobile lamp of automobile industry.
Summary of the invention
In view of the above problems, the purpose of the present invention is to provide a kind of automobile lamp adornment frame technique for vacuum coating, through true
There are noble metal color and anti-fingerprint effect after empty plated film.
The technical scheme is that be accomplished by the following way: a kind of automobile lamp adornment frame technique for vacuum coating,
It is as follows including process:
1. decontamination, cleaning solution being dipped with non-dust cloth, first pass wiping being carried out to outer surface of workpiece, when operation there must be certain power
Degree, is wiped twice when necessary；Then it is wiped second time with dry non-dust cloth, cleaning solution is dehydrated alcohol or isopropanol.
2. electrostatic precipitation is dusted workpiece using electrostatic precipitation rifle, pipette tips are no more than 50mm, work with a distance from workpiece
Air pressure is in 0.4Mpa or more.
3. workpiece is placed on spraying frock by basecoat paint, workpiece surface is sprayed using spray gun for paint, passes through work
The region for being not required to dress spraying is covered.
4. workpiece after spraying is removed from tooling and is placed on UV solidification assembly line, solidified, UV is solid by UV photocuring
The energy fluorescent tube changed on assembly line requires energy between 1500-2500mj/cm2,40 ± 5 DEG C of temperature, frequency device frequency 30~
50HZ solidifies 20-30min.
5. checking the adhesive force of priming paint, after visual examination, sampling carries out baige method, it is desirable that within damage 15%.
6. drying, puts the workpiece in baking oven and dried, 60-70 DEG C of oven temperature, baking time 15-30 min, carry out
Destressing.
7. aluminium film is deposited, by clamping workpiece in plated film tooling, it is put into vacuum chamber vapor deposition aluminium film.
8. protective film coating, by monomer material in closed tank body, temperature is 28 DEG C, pressure 1.0-1.2 atmospheric pressure, volatilization
At gas, it then is charged into vacuum chamber by certain flow, vacuum intraventricular pressure is 30-35Pa by force, under vacuum conditions ion bombardment,
Thin film is formed in workpiece aluminium film surface, the aluminium film surface plated is protected.
9. Work inspection device is packed, visual examination, sampling carries out baige method, high temperature resistant, corrosion resistant detection, packs after OK.
The present invention, aluminizer are once completed under vacuum conditions with protective film coating, and aluminium film is avoided to be aoxidized in an atmosphere,
The performance of film layer is improved, the good appearance of automobile lamp after plating improves the yield rate of automobile lamp.
Specific embodiment
Embodiment:
A kind of automobile lamp adornment frame technique for vacuum coating, including process are as follows:
1. decontamination, cleaning solution being dipped with non-dust cloth, first pass wiping being carried out to outer surface of workpiece, when operation there must be certain power
