Description
Technical field
The utility model is related to mobile phone Curved screen manufacturing technology fields, and in particular to a kind of mask of bend glass cover board.
Background technology
The manufacturing process of the mask of existing mobile phone bend glass cover board is as follows：A flat glass plate is provided, by plane
Glass plate sections are placed on hot-forming rear formation curved-surface structure in curved surface forge die, due to nothing on the glass plate with curved-surface structure
Method screen printing pattern, thus at present be usually used laser engraving mode made on the glass plate sections with curved-surface structure needed for
Pattern.But the laser equipment needed for laser engraving is expensive, considerably increases the mask of mobile phone bend glass cover board
Manufacturing cost, and it is also not high in knee precision by the way of laser engraving.
Utility model content
The technical problems to be solved in the utility model is：Manufacturing cost and the higher song of precision can be substantially reduced by providing one kind
The mask of surface glass cover board.
The technical solution of the utility model is：A kind of mask of bend glass cover board, includes with curved-surface structure
Glass plate sections, it is characterised in that：Further include the figuratum mantle of silk-screen, the mantle is attached to the glass plate with curved-surface structure
On part.
With the above structure, the utility model has the following advantages：
The mask of the utility model bend glass cover board is attached to first by pattern silk-screen on mantle, then by mantle with song
On the glass plate sections of face structure, it is formed mask of the shape pattern as mobile phone bend glass cover board, since mantle can
To carry out silk-screen without laser equipment, the manufacturing cost of the mask of mobile phone bend glass cover board is greatly reduced, and soft
Screen printing pattern on membrane plane, there is no laser engravings the problem of knee precision reduces.
Preferably, the mantle is PET film.PET mantles are easy to be bonded and fitting rear surface is more smooth, so that
Finally formed pattern is more accurate.
Preferably, the PET film is used to be equipped with OCA glue with the one side that the glass plate sections with curved-surface structure fit
Layer.The setting so that fitting is more convenient, and fitting is more efficient.
Preferably, the thickness of the OCA glue-lines is 0.020mm-0.030mm.The OCA glue-lines of Rational Thickness can make PET
Film be bonded with the glass plate sections with curved-surface structure more to be consolidated smooth, and can reduce the position deviation of pattern.
Preferably, the thickness of the OCA glue-lines is 0.025mm.This is set as the optimal value of thickness.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model mantle；
Fig. 2 is the structural schematic diagram for the glass plate sections that the utility model has curved-surface structure；
Fig. 3 is that mantle is fitted in the structural schematic diagram after the glass plate sections with curved-surface structure by the utility model；
In figure：1- has the glass plate sections of curved-surface structure, 2- mantles；
Specific implementation mode
Below in conjunction with the accompanying drawings, and in conjunction with the embodiments the utility model is described further.
Embodiment 1：
A kind of mask of bend glass cover board, includes the glass plate sections 1 with curved-surface structure, further includes that silk-screen is figuratum
Mantle 2, the mantle 2 are attached on the glass plate sections 1 with curved-surface structure.
The mask of the utility model bend glass cover board is first by pattern silk-screen on mantle 2, then mantle 2 is attached to has
On the glass plate sections 1 of curved-surface structure, it is formed mask of the shape pattern as mobile phone bend glass cover board, due to mantle
2 can carry out silk-screen without laser equipment, greatly reduce the manufacturing cost of the mask of mobile phone bend glass cover board, Er Qie
Screen printing pattern in 2 plane of mantle, there is no laser engravings the problem of knee precision reduces.
Preferably, the mantle 2 is PET film.PET mantles are easy to be bonded and fitting rear surface is more smooth, to make
It is more accurate to obtain finally formed pattern.
Preferably, the PET film is used to be equipped with OCA with the one side that the glass plate sections 1 with curved-surface structure fit
Glue-line.The setting so that fitting is more convenient, and fitting is more efficient.
Preferably, the thickness of the OCA glue-lines is 0.020mm-0.030mm.The OCA glue-lines of Rational Thickness can make PET
Film be bonded with the glass plate sections with curved-surface structure more to be consolidated smooth, and can reduce the position deviation of pattern.
Preferably, the thickness of the OCA glue-lines is 0.025mm.This is set as the optimal value of thickness.
The manufacturing method of the mask of above-mentioned bend glass cover board includes the following steps：
(1) a flat glass plate is provided, keeps it hot-forming to be formed and bend glass lid in curved surface forge die
The same curved-surface structure of plate；
(2) mantle 2, and the screen printing pattern on mantle 2 are provided；
(3) mantle 2 is attached on the glass plate sections 1 with curved-surface structure.
Preferably, mantle 2 is attached to the glass with curved-surface structure by full-automatic 3D vacuum attaching machines in the step (3)
On glass plate part 1, the full-automatic 3D vacuum attaching machines be the prior art, in the production of subsequent mobile phone Curved screen can by with
It arrives, therefore does not increase the component additionally.Full-automatic 3D vacuum attaching machines can realize automatic attaching, and not only work efficiency is high, and
And product is bonded under vacuum, product bubble-free, product surface is more smooth, to keep fitting more accurate.
Preferably, the full-automatic 3D vacuum attaching machines have CCD automatic vision alignment systems, fitting vacuum degree small
In 1.1torr, binding temperature is 0-110 DEG C, and the fitting time is 30S-40S.CCD automatic vision alignment systems are used when fitting
Desired para is captured, Anawgy accuracy is high, and the vacuum degree height the smooth after being bonded more is not likely to produce bubble, and binding temperature is according to glass knot
Structure material is selected, and is in addition bonded time much shorter than laser carved pattern takes, laser engraving takes will be at 20 minutes
More than.
Preferably, hot-forming process of the flat glass plate in curved surface forge die includes the following steps：
(a) flat glass plate is put into curved surface forge die and flat glass plate is heated；
(b) the progress first time forging and stamping when temperature rise is to 705 DEG C -715 DEG C, forge pressure 0.25Mpa-0.35Mpa,
Forge time is 120S-160S；
(c) it carries out second when temperature continues to rise to 715 DEG C -725 DEG C to forge and press, forge pressure 0.65Mpa-
0.75Mpa, forge time 120S-160S；
(d) temperature is begun to decline, and third time forging and stamping, forge pressure 0.65Mpa are carried out when dropping to 685 DEG C -695 DEG C
- 0.75Mpa, forge time 120S-160S.
Above-mentioned setting makes glass plate sections after multiple high temp forges and presses and the annealing that cools down, and product shaping rate is high, shape performance
Stablize, and internal stress and various tissue defects can be eliminated well.
