Further, the utility model proposes the method for maintaining of Mobile phone screen workpiece based on above-mentioned workover rig, including with
Lower step：
Step S0, the glass cover-plate of fragmentation is removed from LCDs；
In the present embodiment, this step S0 includes following sub-step：
Sub-step S01, by have pertusate adsorption plate 11 be heated to 65 DEG C～90 DEG C；
Sub-step S02, the Mobile phone screen workpiece of glass cover-plate fragmentation is placed on adsorption plate 11；And the glass cover-plate of fragmentation
Towards adsorption plate 11, and coverage hole open top；In the present embodiment, between Mobile phone screen and adsorption plate 11, pad is provided with silicon with holes
Rubber cushion, this silicagel pad is used for realizing sealing between Mobile phone screen and adsorption plate 11 and anti-skidding；The center of the hole of silicagel pad
With the hole aligning of adsorption plate 11, so, do not affect the patency of vacuum.
Sub-step S03, by hole bottom opening to hole evacuation so that hole inside produce negative pressure, make the glass of fragmentation
Glass cover plate adsorbs on adsorption plate 11；This vacuum continues 4min-14min.
Sub-step S04, by the tinsel of a diameter of 0.06mm～0.18mm along the glass cover-plate of fragmentation and liquid crystal display
The contact surface of screen is cut, by the bonding damage layer between the glass cover-plate of fragmentation and LCDs, thus by fragmentation
Glass cover-plate removes from LCDs.In the present embodiment, tinsel is Buddha's warrior attendant molybdenum filament.It is appreciated that Buddha's warrior attendant molybdenum filament is
One example, the sufficiently large tinsel of any intensity can adopt.
Here, when the mobile phone screen of glass cover-plate fragmentation is placed on the adsorption plate 11 of heating, tack coat softens, from
And be conducive to cutting.And when by hole bottom opening to hole evacuation, the glass cover-plate of fragmentation is just in the work of atmospheric pressure
With lower absorption on adsorption plate 11.Now, carried out along the glass cover-plate of fragmentation and the contact surface of LCDs using tinsel
Cutting, you can the glass cover-plate of fragmentation and LCDs are separated.
In other embodiments, the mobile phone screen of glass cover-plate fragmentation can also be processed by the way of microwave heating, with
Sample can be reduced the adhesion strength between glass cover-plate and LCDs.
Sometimes, glass cover-plate excessively fragmentation, the glass cover-plate of fragmentation cannot seal the open top of coverage hole, when giving
It is impossible to adsorb glass cover-plate on adsorption plate 11 during hole evacuation.For this situation, before sub-step S02, also wrap
Include：Stick the glass cover-plate of fragmentation using adhesive tape.So, when by hole bottom opening to hole evacuation, hole will not
Gas leakage, glass cover-plate can be firmly adsorbed on adsorption plate 11.
Step S1, new glass cover plate setting up and down will be kept to put in seal box 1 (specifically to come together with LCDs
Say, be that the new glass cover plate being coated with OCA optical cement positions for keep upper-lower position to arrange with LCDs mould, can
To understand, OCA optical cement can also be coated in LCDs, if additionally, not having polaroid or partially in LCDs
Mating plate damages, and needs to install polaroid in LCDs in advance)；By internal for seal box 1 evacuation, then drive heating platen
Heat and apply pressure to this new glass cover plate, so that this new glass cover plate is fitted in described LCDs, thus completing new
Laminating between glass cover-plate and LCDs, i.e. the laminating of Mobile phone screen workpiece；Wherein, to the heating of new glass cover plate heating
Temperature is 45 DEG C～60 DEG C, and the moulding pressure to the pressurization of new glass cover plate is 0.2MPa～0.5MPa, is taken out true inside seal box 1
Sky is less than 2kPa to vacuum；
In this step, new glass cover plate is to be pasted onto in LCDs by OCA optical cement.Afterwards, add in heating
Under the process conditions of pressure, new glass cover plate and LCDs can fit together securely.After the completion of this step, new glass
Be possible between cover plate and LCDs have minute bubbles, and if process regulation precisely, new glass cover plate and liquid crystal
It is likely to bubble-free between display screen.
Step S2, to the internal insufflation gas of seal box 1, make the pressure within seal box 1 be in 0.3MPa～0.6MPa it
Between；Meanwhile, to the internal heating of seal box 1, make seal box 1 internal temperature be 40 DEG C～55 DEG C, and keep 3min～15min.
Step S2 is creative important practical novel point of the present utility model.Preferably, in the present embodiment, give
The internal insufflation gas of seal box 1, make the pressure within seal box 1 be between 0.3MPa～0.6MPa；Here, work as seal box
When pressure within 1 is 0.4MPa, the de-bubble effect of Mobile phone screen workpiece and efficiency comparison equalize.By in high pressure and hotter
Under environment, if there is bubble between new glass cover plate and LCDs, this bubble can the air pressure within seal box be made
With under be extruded, and being dispersed in OCA glue, cannot differentiating to naked eyes, thus realizing de-bubble effect.
Upon step s 2, also include：Gases at high pressure within seal box 1 are discharged.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
And all these modifications and variations all should belong to the protection domain of this utility model claims.
