Description
Technical field
The present invention relates to cell phone back photosphere production field, especially a kind of production technology of novel mobile phone backlight composite layer.
Background technique
In the electronics industry, backlight is a kind of form of illumination, is commonly used for LCD and shows.LED backlight is used in small
Ingeniously, in LCD panel inexpensively.Its light is usually coloured, although white backlight is more and more universal.Electrooptic panel
It is often employed in large-scale display, at this moment uniform backlight is critically important.As present mobile phone more and more quickly develops,
The backlight composite layer of mobile phone is also required to constantly improve.
Currently, mobile phone backlight composite layer includes the upper brightening piece, lower brightening piece, diffusion sheet, LED successively stacked from the top down
Lamp, light guide plate and reflector plate when processing, first cut into each layer material the size of requirement, then that each layer bonding is integral i.e.
It can.Light leakage is link important in backlight composite layer quality, and the light leakage of backlight composite layer on the market is mainly logical at present
The frame of black glue and periphery is crossed, but the black glue of light leakage is predominantly located at the outer layer of backlight composite layer, it is anti-inside backlight composite layer
Light leakage still has gaps and omissions, and the light leakage inside backlight composite layer cannot use black glue, multiple in backlight because the thickness of black glue is thicker
Closing layer internal applications black glue will lead to inner layers and cannot fit closely, thus use ink carry out the envelope luminous energy solution at edge with
Upper problem.But for the production compared to conventional backlight composite layer, more this procedure of ink edge sealing, conventional back
The production that the production procedure of photoreactivation layer is obviously not suitable for ink edge sealing needs, it is therefore necessary to propose that a kind of new production technology is come
It solves the above problems.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of production technology of novel mobile phone backlight composite layer, so as to
Improve the envelope light effect of backlight composite layer.

Source LED effect is designed, and printing ink colors need to debug referring to LED light；Changed by the ink colors of printing with size
The light-out effect of kind backlight, the uniformity and brightness of Mobile phone lighting is reached with this, print structure is in addition to drawing requirement, after consideration
Process cross cutting positioning can add 4 small sircle holes (diameter 2-4mm) of print outside product；
Diffusion sheet and light guide plate material after slitting is cut enter printing machine, and printing machine is positioned by the printing at feeding end
Inductor is correct to need the position of printed patterns when ensuring that material enters printing machine, and the scraper of printing machine prints ink by halftone
It brushes on material, the printed product of printing machine examines inductor to determine printed product quality according to the color after printing；
(3) punching: each layer material of novel mobile phone backlight composite layer is required to punch by perforating press and position, after printing
Material enters punching step, and 4 small sircle holes that the punching positioning inductor of perforating press is printed in print steps by detection are fixed
The position of position punching,
Material enters in perforating press through the punching feed mechanism of perforating press, at this time the object of punching feed mechanism and punch mechanism
Material keeps straight line directly to play positioning if material is within the scope of the punching of perforating press, if material slightly deviation, punching
Machine automatic identification and can adjust position, if material deviation has exceeded the adjusting range of perforating press, machine is sounded an alarm；Punching
Punching finished product detection inductor detection after finishing through perforating press exit, can shut down concurrent responding when having the bad situation of punching
Report,
(4) be die cut: each layer material of novel mobile phone backlight composite layer is required to cut by cross cutting, and upper brightening piece needs to paste
