Abstract
The present invention provides a kind of polarisation sheet method for straightening warp, polarisation sheet is placed in cylinder by this method, then is placed under the conditions of suitable environment temperature, temperature together, certain time is corrected, to corrected the product of warpage NG again as qualified products.The present invention overcomes the places of prior art, device requirement constraint；It is with the obvious advantage in terms of cost, specific aim correction is done to the finished product of warpage NG, reduces the waste of cost；Correction tool structure is simple, not high to environmental requirement precision, and batch may be implemented and correct.
Description
Technical field
The present invention relates to the post-processing field of finished product polarizer, especially a kind of polarisation sheet method for straightening warp.
Background technique
When coiled material polaroid finds there are warpage issues when cutting, generally use to the polarisation coiled sheet for being not processed into sheet material
Material carries out the exchange cards containing all personal details and become sworn brothers mode of protective film of heavy industry and calibrates warpage；The product for having cut into sheet material warpage NG then can only be reported all
Useless processing；To because visitor caused by warpage NG moves back warpage NG product caused by product or lengthy warehousing and also can only all scrap place
Reason.
The above-mentioned processing mode to sheet material warpage, there is defects below:
(1) it examines anti-operation and needs equipment, material, human cost investment, and have certain loss；
(2) correction warpage cannot be completely secured in polaroid re-posted protective film (examining anti-operation), there is certain probability of failure；
It (3) is to scrap processing, cost of idleness to the product of warpage NG at present without antidote.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of polarisation sheet method for straightening warp, mainly for
It because of the sheet material of warpage NG, is corrected under particular circumstances, meets customer specifications, scrap is become into non-defective unit.
The principle of warpage is: polarisation sheet is multilayered structure, and each layer is bonded with glue.In polarisation sheet
Membrane material can be drawn high with compared with hightension in manufacturing process, membrane material can bounce back after pulling force disappears.Glue can be shunk in the drying process, film
Material can also bounce back in the drying process.Since there are two retraction process, different membrane material retraction degree is different, will be in polarisation
The formation internal stress between layers of sheet, if internal stress balances warpage with regard to OK, if internal stress is uneven between each other
Warpage issues (just stick up and bear and stick up NG) will be generated.
The principle of correction is: the one of the inside warpage of polarisation sheet being placed in cylinder down, in certain environment
Under the conditions of equably discharge the unbalanced internal stress of polarisation sheet in certain time, correct polarisation sheet warpage,
Meet customer specifications.
Technical scheme is as follows:
A kind of polarisation sheet method for straightening warp, comprising the following steps:
S1 down by the one of the inside warpage of polarisation sheet is put into corresponding cylinder, the size of polarisation sheet
With the relationship of corresponding circular cylinder radius are as follows:
Cylinder is placed on 30~80 DEG C of temperature together with polarisation sheet by S2, in the environment of humidity 20~90%, correction
1~48hr of time, product warpage are corrected.
As a further improvement of the present invention, the warpage degree of polarisation sheet is higher, thickness is bigger, then the environment corrected
Temperature it is higher, the improvement time is longer；Environment temperature is 40-60 DEG C, and the improvement time is 12~r for 24 hours.
As a further improvement of the present invention, the moisture content of polarisation sheet is higher, then the humidity of the environment selected is higher；
The moisture content of polarisation sheet material is below 0.1%, and the humidity of environment is 20-50%；The moisture content of polarisation sheet material 0.1% and with
On, the humidity of environment is 60-90%.
As a further improvement of the present invention, further include S3, correct endpoint: after choosing correction condition, first lacking
The correction test of warp products is measured, timing takes out whether measurement warp products meet customer specifications, if meeting customer specifications,
It may determine that correct terminal, record correction condition, carry out scale is high-volume corrected；Ideal correction terminal is that quadrangle and four sides are stuck up
Song is zero.
Compared with prior art, the invention has the benefit that
(1) new technology overcomes the place of prior art, device requirement constraint；
(2) with the obvious advantage in terms of cost, specific aim correction is done to the finished product of warpage NG, reduces the wave of cost
Take.
(3) correction tool structure is simple, not high to environmental requirement precision, and batch may be implemented and correct.
Detailed description of the invention
Fig. 1 is the polarizer sheet structure figure of warpage NG of the invention a kind of.
Fig. 2 is the polarisation sheet in being corrected using antidote of the invention.
Fig. 3 is to have arrived at the polarisation sheet of correction terminal using antidote of the invention.
Specific embodiment
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, with reference to the accompanying drawing and specifically
The present invention is further described for embodiment.
Embodiment 1
It corrects endpoint: after choosing correction condition, first doing the correction test of a small amount of warp products, measurement is taken out in timing
Whether warp products meet customer specifications, if meeting customer specifications, may determine that correct terminal, record correction item
Part, carry out scale are high-volume corrected；Ideal correction terminal is quadrangle and four side warpages are zero.
The polarisation sheet of warpage NG is put into cylinder, as shown in Figure 1-3, correction condition such as table 1, correction result such as table
2。
Table 1 corrects condition list
| Correction condition | Temperature | Humidity | Cylinder | Sheet thickness | Sheets of sizes | Improvement time |
| Parameter | 40℃ | 40% | 12 cun | 306μm | 19 cun | 24hr |
2 correction result of table measures table
Embodiment 1 the results show that antidote of the invention overcomes the place of prior art, device requirement condition
Constraint；It is with the obvious advantage in terms of cost, specific aim correction is done to the finished product of warpage NG, reduces the waste of cost；Correction
Tool construction is simple, not high to environmental requirement precision, and batch may be implemented and correct.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
