Printed pattern has the effect of exquisite and anti-counterfeit capability and fastness, entire manufacturing process can be made more environmentally-friendly using UV ink.
In order to achieve the above object, the present invention provides a kind of environment-friendly type moulding process of LCD cover, including it is as follows
Step：
Feed process：Scroll-like aluminum sheet is fed by conveyer, the ridge orientation of aluminum sheet is parallel to aluminum sheet
Long side direction, long side direction are feedstock direction, and by laminating machine in product one side film, overlay film uses UV uv equipments；
Punch forming process:1) shell shape is gone out to aluminum sheet, is adopted using full blanking using 110T tonnage punching machines
Punching press is carried out to the aluminum sheet with shell shape with convex formpiston is rushed；2) it is tried using soft material before the mold of punching press LOGO molds
Operation is tested, the coefficient of resilience estimates verification 2~3 times, using surface there is the staking punch of curved shape lines outstanding to carry out for the first time
Then there is using surface the staking punch of the diamond shape lines of recess to carry out second of punching press, finally use surface smooth for punching press
Staking punch carries out third time punching press, gradually from the superficial to the deep gets LOGO, dumb light and bright when the dark figure line of LOGO has following process
The effect of light effect balance；3) punching machine of 110 tonnages is used first to pre-bend 70 ° four sides of shell, bending male model is according to crimping
Molding, then pre-bends 90 ° to four sides of shell using 160 tonnage punching machines again, and bending male model is molded according to crimping negative clearance,
The punching machine of 110 tonnages is finally used to push away negative angle to shell side, it is 20 ° that side, which is buckled to angle,；4) punching press upper and lower mould uses excellent power
Glue carrys out the flatness of shaping product；
CNC processes, by each dimensioned of product to defined thickness and shape, the milling anode hanging point in the bending of product,
The wide 0.5mm of anode hanging point, long 30mm, depth 0.3mm；
Polishing operation, polish product surrounding and master mold face, polishing are repaired product surface and are touched caused by punching press, the CNC processing procedures
It scratches, uses grinding disc for sand paper roughening surface, limited when using sand paper refining surfaces polishing jig surrounding, avoid four
Circumferential edges are damaged, and flatness shaping is then carried out；
Sandblasting and anode colouring process, carry out positive and negative sandblasting using metal sand, first spray reverse side, and rear spray front provides sun
Pole colour table, experiment carry out anode colouring after confirming specific color, finally carry out laser carving and break oxygen；
Silkscreen process, using UV ink on printing surface printed pattern, after finishing printing using ultraviolet light, infrared light
And visible red is irradiated UV ink 0.2 second, the ratio of ultraviolet light, infrared light and visible red is respectively 50%,
30%, 20%, ensure that ink is in the leather hard for being suitble to further print, then using screen process press in half-dried figure
Upper type metal powder infrared printing ink makes UV ink and metal powder infrared printing ink merge, and uses ultraviolet light and visible red
Ratio be respectively that solidification is dried to entire printed pattern in 60%, 40% illumination, then printed matter is consolidated using hot wind
Change；
Glue process in automation, wherein dispensing 45S, take 8S, and hot pressing 90S, take 30S, the tentative deformation of degree of deformation management and control
Direction is face-up；Punch section long side<0.8mm；Broadside<0.6mm；Sandblasting segment length side<1.0mm；Broadside<0.8mm；Assembling
Duan Changdu≤1.0mm；Kuan Bian≤0.8mm；
And group founds process, and the lid after gluing is assembled.
Compared with prior art, the application can save process time using the mode of first punching press, then CNC；Using three times
The technique of continuous punching, to obtain the logo effects of exquisite matte and glossy effective balance；Using the ultraviolet of corresponding proportion
The technique of light, infrared light and visible red combined illumination can obtain it is expected half dry ink of molten condition；Using in half drier oil
The technique of type metal powder infrared printing ink on black figure so that printed pattern has the effect of exquisite and anti-counterfeit capability and jail
Solidity can make entire manufacturing process more environmentally-friendly using UV ink.
