And stripping off device 1 also comprises: the 1st supporting member 9, it is configured in and batches component 5 and peel off between auxiliary part 7, for being pressed towards platform component 3 by duplexer 30, thus comes together to clamp and supporting stack 30 with platform component 3.Stripping off device 1 also comprises: the 2nd supporting member 11, it is configured in the side contrary with batching component 5 (be positioned in FIG and keep left the position of side than peeling off auxiliary part 7) across peeling off auxiliary part 7, for the substrate 31 exposed because Polarizer 33 is stripped is pressed towards platform component 3, come together to clamp with platform component 3 and support this substrate 31.
Stripping off device 1 also comprises fixing member 15.Above-mentioned batch component 5, peel off auxiliary part 7, the 1st supporting member 9 and the 2nd supporting member 11 be fixed on platform component 3 by this fixing member 15 respectively.
Platform component 3 be to whole Polarizer 33 by the whole period peeling off from duplexer 30 for loading the platform of duplexer 30.
Batch the end 33b of Polarizer 33 of component 5 for rolling up frame and peeling off, and further Polarizer 33 is peeled off by rotating and this Polarizer 33 is wound up successively in this condition.
Batching component 5 and such as can list the driving of drive units such as being subject to motor 17 and the roller etc. rotated like this.
And an end 33b of the above-mentioned Polarizer 33 be stripped is fixed on by splicing tape (not shown) etc. and batches on component 5.
In addition, what represent in fig. 2 is the state that Polarizer 33 is stripped together with adhesive phase 35 (with reference to Fig. 9).
As shown in Figure 2 and Figure 3, peel off the tabular of auxiliary part 7 in lengthwise, and there is bottom surface sections 7a and top ends 7b.And, in the present embodiment, peel off auxiliary part 7 and also have: rake 7c, its with from top ends 7b towards base end side (downstream of direction of delaminate X, the right side in Fig. 3) and the mode leaving bottom surface sections 7a tilt.
This stripping auxiliary part 7 is formed as: length (maximum length) L on the direction (direction of delaminate X) of its tip side towards base end side is greater than height (maximum height) H from its bottom surface (surface of bottom surface sections 7a).
Preferably, this height H is 1:3 ~ 1:5 with the ratio (H:L) of length L.
And preferably, height H is 15mm ~ 20mm, length L is 50mm ~ 75mm.
Bottom surface sections 7a configures along the face 33a by Polarizer 33 side of duplexer 30.Specifically, bottom surface sections 7a be configured in can realize following object position on: when utilize peel off auxiliary part 7 Polarizer 33 is peeled off time, bottom surface sections 7a contacts with duplexer 30 and then suppresses this duplexer 30 to float.Contact with duplexer 30 as long as the configuration mode of this bottom surface sections 7a can realize this bottom surface sections 7a when above-mentioned stripping and then suppress this duplexer 30 to float, being just not particularly limited.Such as, before the stripping of utilization stripping auxiliary part 7 starts, bottom surface sections 7a both can be configured to contact with the face 33a by Polarizer 33 side, also can be configured in the vicinity of this face 33a and not contact with this face 33a.
Top ends 7b is arranged in than batching the position of component 5 by upstream side (left side of Fig. 1) on direction of delaminate X (direction of tip side towards base end side from peeling off auxiliary part 7).By this configuration mode, the Polarizer 33 peeled off can be made to bend along the top edge 7ba of top ends 7b, and this Polarizer 33 can be guided to the base end side (downstream of direction of delaminate X) of this stripping auxiliary part 7.That is, the Polarizer 33 peeled off can be guided to and batch component 5.
The radius of curvature R of the top edge 7ba of this top ends 7b is also not particularly limited, and can suitably set.
At this, as mentioned above, because the bonding force between Polarizer 33 and substrate 31 is high, therefore, in stripping starting point S vicinity, the Polarizer 33 be stripped is difficult to follow top ends 7b (top edge 7ba).And, as shown in Figure 4, exist and be inclined to as follows: when the radius of curvature R of top ends 7b is larger, the gap between the Polarizer 33 be stripped and top ends 7b is larger.That is, the position in the contact portion M of starting point S easily between distance top ends 7b and duplexer 30 (upstream side, the left side in Fig. 4) comparatively far away is peeled off.
On the other hand, as shown in Figure 5, exist and be inclined to as follows: when top ends 7b radius of curvature R more hour, the gap between the Polarizer 33 be stripped and top ends 7b is less.That is, the position on the contact portion M of starting point S easily between distance top ends 7b and duplexer 30 comparatively near (downstream, the right side in Fig. 5) is peeled off.
And, when gap between the Polarizer 33 be stripped and top ends 7b is larger, via top ends 7b conversion, easily on the length direction (direction vertical with direction of delaminate X) peeling off auxiliary part 7, produce deviation for the power peeled off by Polarizer 33.And substrate 31 easily ruptures.
And according to technical general knowledge, when radius of curvature R is too small, top ends 7b can be too sharp-pointed, and easily cut off by Polarizer 33.
Thus, such as, consider that above-mentioned viewpoint suitably sets the radius of curvature R of the top edge 7ba of top ends 7b, preferably, this radius of curvature R is 2.5mm ~ 17.5mm.
By making the radius of curvature R of top ends 7b be below 17.5mm, the stripping starting point S of Polarizer 33 can be made near the contact portion M between duplexer 30 and bottom surface sections 7a.Thus, via top ends 7b transmit come, be difficult to produce deviation on the bearing of trend (direction vertical with direction of delaminate X) of top ends 7b for the power that Polarizer 33 is peeled off, therefore, be more difficult to cause Polarizer 33 to break.In addition, substrate 31 can be suppressed further to rupture.
And, by making the radius of curvature R of top ends 7b be more than 2.5mm, top edge 7ba can be suppressed to become too sharp-pointed, thus can be difficult to cause Polarizer 33 to be cut off.
Thus, can more easily Polarizer 33 be peeled off from substrate 31.
Rake 7c is used for being guided the Polarizer 33 of coming to guide to the base end side (downstream of direction of delaminate X) peeling off auxiliary part 7 further by top ends 7b.
By making stripping auxiliary part 7 have rake 7c, can make the Polarizer 33 be stripped after being guided by top ends 7b, can also be guided by rake 7c further.That is, have passed through top ends 7b after the path of Polarizer (Polarizer be stripped) 33 can be maintained in the angle θ 1 of regulation by rake 7c.Thereby, it is possible to suppress the above-mentioned angle θ 1 of the Polarizer 33 be stripped to change, therefore, it is possible to suppress the tension force putting on top ends 7b caused because this angle θ 1 changes to change.
Like this, the equilibrium state collapse putting on the tension force peeling off auxiliary part 7 can be suppressed further, therefore, it is possible to more easily peeled off from substrate 31 by Polarizer 33.
Preferably, this rake 7c is 10 ° ~ 30 ° relative to the face T angulation θ 1 parallel with duplexer 30.
Like this, by making the angle θ 1 of rake 7c be 10 ° ~ 30 °, the Polarizer 33 be stripped can be utilized to be pressed to duplexer 30 by stripping auxiliary part 7, and, this Polarizer 33 can be guided to base end side.
Thus, stripping auxiliary part 7 can be made more stable, thus can more easily Polarizer 33 be peeled off from substrate 31.
