Now, as shown in figure 3, the concrete technology flow process of step S120 can be：
Second film layer 150 of OCA is attached to the surface relative with the first laminating platform 100 of the second laminating platform 50,
As shown in (I) figure in Fig. 2.For example, the second laminating platform 50 can adsorb OCA by way of vacuum suction.Wherein, OCA
Length and the length of first substrate 200 between difference be δ L1, the length of tool 400 is L, δ L1≤L.
First film layer 450 of OCA is peeled off.Specifically, as shown in (I) figure in Fig. 3, can be by dyestripping roller 350
First film layer 450 of OCA is peeled off, dyestripping roller 350 is contacted the first film layer 450 positioned at OCA first ends 310, by dyestripping
The film-tear adhesive band on the surface of roller 350 in the first direction gets off first film layer 450 of OCA from the sur-face peeling of glue-line 300.
The first laminating laminating platform 50 of platform 100 and second is driven to be aligned, when completion is aligned, in Fig. 3
(II) shown in figure, incline second and fit platform 50 so that the first end 310 for being adsorbed in the OCA on the surface of the second laminating platform 50 is approached
The first surface 410 of tool 400.Wherein, the first surface 410 of tool 400 is tool 400 away from the first laminating platform 100
Surface.That is so that first surface 410 of the glue-line 300 of the first end 310 of OCA close to tool 400.
Because the active position of dyestripping roller 350 is the first end 310 of OCA, and the first end 310 of OCA is not in the first base
On plate 200, but positioned at the first surface 410 of tool 400.Relative to existing applying method, the laminating step is enabled to
Issuable bad such as bubble, glue-line 300 are damaged and focused on the OCA of the first surface 410 for being fitted in tool 400.

Due to laminating roller 250 have certain zone of action, therefore, in order to will it is above-mentioned it is bad (bubble, glue-line damage
Deng) surface of tool 400 is transferred to, the OCA (including the second film layer 150 and glue-line 300) of the first surface laminating of tool 400 exists
The length in the X direction of the zone of action when length of X-direction should be pressurized according to laminating roller 250 is set.The present embodiment
In, the OCA of the first surface laminating of tool 400 is preferably not less than 1 centimetre in the length of X-direction, it is clear that tool 400 is in X-direction
Length L nor less than 1 centimetre.
In above-mentioned application scenarios, step S130 can specifically include below scheme：
Such as (II) figure in Fig. 3, roller 250 of fitting is acted on into the second film layer 150 positioned at OCA first ends 310, driven
Laminating roller 250 is pushed so that the glue-line 300 for being located at OCA first ends 310 is fitted with the first surface 410 of tool 400.Due to patch
The depressed position of roller 250 is closed not on first substrate 200, but positioned at the first surface 410 of tool 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 tool
On the OCA of 400 first surface 410.
Such as (III) figure and (IV) figure in Fig. 3, second is driven to fit its heeling condition of holding of platform 50 relative to the first patch

Hold the first surface close to the tool；
The length in the X direction of second substrate 550 should be greater than length of the first substrate 200 in X-direction.In order to save as far as possible
Material, the width that the width in the Y direction of second substrate 550 can be with first substrate 200 in the Y direction is adapted to, and second
Difference of the length and first substrate 200 in the X direction of substrate 550 between the length of X-direction can be less than or equal to tool
400 length in the X direction.
By the one side of the glue-line 300 of OCA and the first surface 410 of tool 400 and the first surface 210 of first substrate 200
, it is necessary to further second substrate 550 is fitted with the another side of the glue-line 300 after laminating.First second film layer 150 of OCA is shelled
From the glue-line 300, Ran Houzai of the first surface 210 for exposing the first surface 410 and first substrate 200 for being fitted in tool 400
The contraposition of first end 551 of second substrate 550 is fitted on the glue-line 300 of the first surface 410 of tool 400.

Length be L, δ L2≤L.
The first laminating laminating platform 50 of platform 100 and second is driven to be aligned, when completion is aligned, in Fig. 3
(VI) shown in figure, incline second fit platform 50 so that second substrate 550 first end 551 close to tool 400 first surface
410.That is so that glue-line 300 of the first end 551 of second substrate 550 close on the first surface 410 of tool 400.
Step S150, the laminating roller is acted on the first end of the second substrate, drives the laminating roller edge
The first direction rolls the second substrate so that the second substrate fits in the glue-line away from the first substrate
Surface.
Laminating roller 250 is acted on the second substrate 550 on the surface of tool 400, drives laminating roller 250 to push

Roller 250 is slow in the first direction to roll second substrate 550 so that second substrate 550 is pasted with the another side of the glue-line 300 of OCA
Close, complete first substrate 200 and fitted with the OCA between second substrate 550.Similarly, because the laminating depressed position of roller 250 does not exist
On first substrate 200, but positioned at the first surface 410 of tool 400.Relative to existing applying method, the patch is enabled to
The issuable bad such as bubble of step, the damage of glue-line 300 is closed to focus on and be fitted on the OCA on the surface of tool 400.
In above-mentioned application scenarios, step S150 can specifically include below scheme：Such as (VI) figure in Fig. 3, the is driven
Two laminating platforms 50 keep its heeling condition to be moved in the first direction relative to the first laminating platform 100；And drive laminating roller
250 is in the first direction v directions rolling second substrate 550 in Fig. 3 (III) near the with the motion of the second laminating platform 50
The surface of two laminating platforms 50, so that second substrate 550 departs from the second laminating platform 50, and makes second substrate 550 and tool 400
First surface 410 and first substrate 200 first surface 210 on glue-line 300 fit, complete first substrate 200 and the
OCA laminatings between two substrates 550, as shown in (VII) figure in Fig. 3.
