At this point, as shown in figure 3, the concrete technology flow process of step S120 can be with are as follows:
It is bonded the opposite surface of platform 100 with first by what the second film layer 150 of OCA was attached to the second fitting platform 50,
As shown in (I) figure in Fig. 2.For example, the second fitting platform 50 can adsorb OCA by way of vacuum suction.Wherein, OCA
Length and first substrate 200 length between difference be δ L1, the length of jig 400 is L, δ L1≤L.
The first film layer 450 of OCA is removed.Specifically, dyestripping idler wheel 350 can be passed through as shown in (I) figure in Fig. 3
The first film layer 450 for removing OCA makes the contact of dyestripping idler wheel 350 be located at the first film layer 450 of OCA first end 310, by dyestripping
The film-tear adhesive band on 350 surface of idler wheel gets off the first film layer 450 of OCA from the sur-face peeling of glue-line 300 along first direction.
The first fitting platform 100 of driving and the second fitting platform 50 are aligned, when aligning completion, in Fig. 3
(II) shown in figure, the second fitting platform 50 of inclination is so that the first end 310 for being adsorbed in the OCA on 50 surface of the second fitting platform is close
The first surface 410 of jig 400.Wherein, the first surface 410 of jig 400 is jig 400 far from the first fitting platform 100
Surface.That is, making the glue-line 300 of the first end 310 of OCA close to the first surface 410 of jig 400.
Due to the first end 310 that the active position of dyestripping idler wheel 350 is OCA, and the first end 310 of OCA is not in the first base
On plate 200, but it is located at the first surface 410 of jig 400.Relative to existing applying method, the laminating step is enabled to
Issuable bad such as bubble, the damage of glue-line 300 focus on the OCA for the first surface 410 for being fitted in jig 400.
Fitting idler wheel is acted on second film layer positioned at the Optical transparent adhesive first end, driven by step S130
The fitting idler wheel rolls second film layer so that the glue-line of the Optical transparent adhesive fits in the jig along first direction
First surface and the first substrate first surface；
Due to fitting idler wheel 250 have certain zone of action, in order to will it is above-mentioned it is bad (bubble, glue-line damage
Deng) it is transferred to the surface of jig 400, the OCA (including the second film layer 150 and glue-line 300) of the first surface fitting of jig 400 exists
The length in the X direction of the zone of action when length of X-direction should be pressurized according to fitting idler wheel 250 is arranged.The present embodiment
In, the OCA of the first surface fitting of jig 400 is preferably not less than 1 centimetre in the length of X-direction, it is clear that jig 400 is in X-direction
Length L nor less than 1 centimetre.
In above-mentioned application scenarios, step S130 can specifically include following below scheme:
Such as (II) figure in Fig. 3, fitting idler wheel 250 is acted on into the second film layer 150 positioned at OCA first end 310, is driven
Fitting idler wheel 250 pushes so that the glue-line 300 for being located at OCA first end 310 is bonded with the first surface 410 of jig 400.Due to patch
250 depressed position of idler wheel is closed not on first substrate 200, but is located at the first surface 410 of jig 400.Relative to existing
Applying method enables to the issuable bad such as bubble of the laminating step, the damage of glue-line 300 to focus on and be fitted in jig
On the OCA of 400 first surface 410.
Such as (III) figure and (IV) figure in Fig. 3, driving the second fitting platform 50 keeps its heeling condition relative to the first patch
Platform 100 is closed to move along first direction；And fitting idler wheel 250 is driven to roll with the movement of the second fitting platform 50 along first direction
The second film layer 150 is pressed, so that the second film layer 150 is detached from the second fitting platform 50, and the glue-line 300 of OCA is made to be fitted in jig 400
First surface 410 and first substrate 200 first surface 210.
Step S140 removes the second film layer of the Optical transparent adhesive to expose the glue-line, by the first of the second substrate
Hold the first surface close to the jig；
The length of the second substrate 550 in the X direction should be greater than first substrate 200 in the length of X-direction.In order to save as far as possible
The width in the Y direction of material, the second substrate 550 can be adapted to the width of first substrate 200 in the Y direction, and second
The difference of length and first substrate 200 between the length of X-direction of substrate 550 in the X direction can be less than or equal to jig
400 length in the X direction.
By the one side of the glue-line 300 of OCA and the first surface 410 of jig 400 and the first surface 210 of first substrate 200
After fitting, need further to be bonded the second substrate 550 with the another side of the glue-line 300.First the second film layer 150 of OCA is shelled
Glue-line 300 from the first surface 210 for exposing the first surface 410 and first substrate 200 that are fitted in jig 400, then again
On the glue-line 300 for the first surface 410 that the contraposition of first end 551 of the second substrate 550 is fitted in jig 400.
In above-mentioned application scenarios, step S140 can specifically include following below scheme:
Second film layer 150 of the Optical transparent adhesive is removed to expose the glue-line 300.Such as (V) figure institute in Fig. 3
Show, the second film layer 150 of OCA can be removed by dyestripping idler wheel 350, dyestripping idler wheel 350 is acted on positioned at OCA first end
310 the second film layer 150, driving dyestripping idler wheel 350 is moved from the first end 310 of OCA, along first direction, by dyestripping idler wheel
The film-tear adhesive band on 350 surfaces gets off the second film layer 150 of OCA from the sur-face peeling of glue-line 300.Similarly, relative to existing patch
Conjunction method, so that the laminating step is issuable bad as bubble, the damage of glue-line 300 focus on being fitted in jig 400
On the OCA of first surface 410.
By the second substrate 550 be attached to it is described second fitting platform 50 with described first be bonded platform 100 relatively
Surface, as shown in (V) figure in Fig. 3.Specifically, the second substrate 550 can be attached to by way of vacuum suction
Two fitting 50 surfaces of platform.Difference between the length of the second substrate 550 and the length of first substrate 200 is δ L2, jig 400
Length be L, δ L2≤L.
The first fitting platform 100 of driving and the second fitting platform 50 are aligned, when aligning completion, in Fig. 3
(VI) shown in figure, inclination second fitting platform 50 so that the second substrate 550 first end 551 close to jig 400 first surface
410.That is, making the first end 551 of the second substrate 550 close to the glue-line 300 on the first surface 410 of jig 400.
The fitting idler wheel is acted on the first end of the second substrate, drives the fitting idler wheel edge by step S150
The first direction rolls the second substrate so that the second substrate fits in the glue-line far from the first substrate
Surface.
Fitting idler wheel 250 is acted in the second substrate 550 on 400 surface of jig, driving fitting idler wheel 250 pushes
So that the first end 551 for being located at the second substrate 550 is bonded with the glue-line 300 on the first surface 410 of jig 400.Driving fitting
Idler wheel 250 slowly rolls the second substrate 550 along first direction, so that another face paste of the glue-line 300 of the second substrate 550 and OCA
It closes, completes first substrate 200 and be bonded with the OCA between the second substrate 550.Similarly, since fitting 250 depressed position of idler wheel does not exist
On first substrate 200, but it is located at the first surface 410 of jig 400.Relative to existing applying method, the patch is enabled to
Close the issuable bad such as bubble of step, the damage of glue-line 300 focuses on the OCA for being fitted in 400 surface of jig.
In above-mentioned application scenarios, step S150 can specifically include following below scheme: such as (VI) figure in Fig. 3, driving the
Two fitting platforms 50 keep its heeling condition to move relative to the first fitting platform 100 along first direction；And drive fitting idler wheel
250 as v direction rolling the second substrate 550 of the movement of the second fitting platform 50 in first direction, that is, Fig. 3 (III) is close to the
The surface of two fitting platforms 50 so that the second substrate 550 is detached from the second fitting platform 50, and makes the second substrate 550 and jig 400
First surface 410 and first substrate 200 first surface 210 on glue-line 300 be bonded, complete first substrate 200 and the
OCA fitting between two substrates 550, as shown in (VII) figure in Fig. 3.
Step S160, removal are located at the second substrate and the glue-line on the first surface of the jig.
After the completion of fitting, in the junction of jig 400 and first substrate 200, the second substrate 550 (containing glue-line 300) is cut
It isolates, the second substrate 550 for being fitted in 400 surface of jig and glue-line 300 is cleared up as waste material, first substrate 200
The second substrate 550 of surface fitting is really to bring the part of product into, as shown in (VIII) figure in Fig. 3.
In the present embodiment, first substrate 200 is hard substrate, and the second substrate 550 is flexible base board.For example, first substrate
200 can be optical glass, and the second substrate 550 can be Grating Film.In the present embodiment, with no restrictions to the material of jig 400,
It can be metal, alloy material, plastic material, glass substrate etc., the first side 420 close to first substrate 200 is (with plane
ZOY is parallel) it is smoother surface.
It is understood that a large amount of OCA glue-line 300 fits to the of jig 400 after jig 400 is reused many times
It will lead to jig 400 when one surface 410 gradually to thicken, even more than the thickness h of first substrate 200.It is preferable due to reach
It is bonded effect, needing the difference of the thickness of jig 400 and the thickness of first substrate 200, therefore, it is necessary to regular within a preset range
Jig 400 is purged or replaced to the waste material on 400 surface of jig.
The Optical transparent adhesive applying method that first embodiment of the invention provides is by introducing jig 400, during fitting
