As shown in Figure 1, removing portion 400 is being set between a pair of guided way 100 to the position that X-direction is left from objective table portion 110.And remove portion 400 and be positioned on the direction vertical that (Fig. 2 does not have expression than the position of objective table portion's 110 farther (downsides of Fig. 2) apart from guided way 100 for the bearing-surface (paper of Fig. 1) of objective table portion 110.With reference to Fig. 7, Fig. 8).Remove portion 400 and preferably include two bar-like members 410,420.Bar-like member 410,420 is parallel to each other, and the guided way 100 of both sides vertically extends relatively.The interval of bar-like member 410,420 can be changed, and both are adjacent to.
The both ends of body 310 and each guided way 100 links, and can move in X-direction along guided way 100.Body 310 is further linked by the bar-like member vertical with guided way 100 between its both ends.
At the both ends of body 310 linking part 330 is set respectively.Fig. 3 represents near the enlarged drawing the linking part 330.As shown in Figure 3, the preferably crooked thin flat arm of linking part 330.The end of turning cylinder 331 and bending point link.Linking part 330 can rotate around it axle 331 and rotate.As shown in Figure 1, turning cylinder 331 relative guided way 100 between guided way 100 vertically extends.The two ends of turning cylinder 331 are fixed on the both ends of body 310.
One end of linking part 330 links by cylinder 320 and body 310.Cylinder 320 makes this end of linking part 330 and the distance between body 310 bound fractions flexible and linking part 330 moving axis 331 that rotates is rotated.
As shown in Figure 1, stripper roll 340 is rollers of elongate cylindrical shape, and the guided way 100 of both sides vertically extends relatively.Central shaft 341 ends of stripper roll 340 are fixed on the other end of linking part 330.Stripper roll 340 can be around central shaft 341 rotations.As shown in Figure 3, by making rotate moving axis 331 of linking part 330 rotate and the outer peripheral face of stripper roll 340 is contacted with the surface of polarizer 1 (particularly diaphragm 2) or separate.Preferably the outer peripheral face in stripper roll 340 is formed with adhesive linkage.When the surface of the outer peripheral face that makes stripper roll 340 with diaphragm 2 contacts, then diaphragm 2 just is bonded on this adhesive linkage.Preferably near the outer peripheral face central authorities of stripper roll 340, be formed with groove 342 as shown in Figure 1.
As shown in Figure 1, clamp portion 350 is the plate-shaped member of rectangle preferably, linking between a pair of linking part 330.In two long legs of clamp shown in Figure 1 portion 350 divided, on the turning cylinder 331 that is fixed on linking part 330 as shown in Figure 3, another was as shown in Figure 3 near the outer peripheral face of stripper roll 340.When linking part 330 rotate that moving axis 331 rotates and the outer peripheral face that makes stripper roll 340 when the surface of polarizer 1 is left, then the opposition side of outer peripheral face contacts (with reference to Fig. 5) with the surface (contact site) 352 of clamp portion 350 another long legs branches.At this moment, preferably be recessed into the curvature identical with stripper roll 340 outer peripheral faces with the contact site 352 that the outer peripheral face of stripper roll 340 contacts.Like this, contact site 352 integral body just can be pushed the outer peripheral face of stripper roll 340 with uniform pressure.Clamp portion 350 also can be a pair of thin bar-like member that links respectively with each linking part 330.At this moment, also can be that the bar-like member parallel with stripper roll 340 is fixed on the contact site 352, the part of this bar-like member or whole and contact site 352 are similarly pushed the outer peripheral face of stripper roll 340.
As shown in Figure 3, clamp portion 350 (particularly its front end) preferably is provided with sensor 360.Preferably when the outer peripheral face of stripper roll 340 contacts with the contact site 352 of clamp portion 350, the diaphragm 2 whether groove 342 (with reference to Fig. 1) that sensor 360 detects stripper roll 340 outer peripheral faces is bonded in stripper roll 340 outer peripheral faces stops up.Preferred sensor 360 is optical sensors, is provided with light source at groove 342 places of stripper roll 340.Light source preferred emission infrared ray.In addition, also can be provided with ultrasound source at groove 342 places of stripper roll 340 for sensor 360 is ultrasonic sensors.Outer peripheral face in stripper roll 340 is bonded with under the situation of diaphragm 2, and groove 342 is stopped up by this diaphragm 2, and the light that sends from the light source of groove 342 is covered by this diaphragm 2.Therefore, sensor 360 can not detect this light.On the contrary, do not have under the situation of bonding diaphragm 2 at the outer peripheral face of stripper roll 340, then sensor 360 can detect the light that sends from the light source of groove 342.Like this, whether detect light and can judge whether diaphragm 2 is peeled off from polarizer 1 according to sensor 360.
On one side following one side describes above-mentioned device is removed diaphragm 2 from polarizer 1 the method for removing of using in detail with reference to Fig. 4～Fig. 8.
Phase I, push an end of linking part 330 and rotate moving axis 331 of linking part 330 is rotated by cylinder 320.Like this, then as shown in Figure 3, make the surface of the polarizer 1 of the outer peripheral face of stripper roll 340 and objective table portion 110 upper supports, particularly contact with the end points K of diaphragm 2.At this moment, owing to be present in the adhesive linkage on stripper roll 340 surfaces and the end face of diaphragm 2 is adjacent to, so the end of diaphragm 2 is bonded in the outer peripheral face of stripper roll 340.
Second stage makes the outer peripheral face contact of stripper roll 340 motionless on the surface of diaphragm 2, utilizes handover portion 200 and makes diaphragm stripping portion 300 move (with reference to Fig. 1) at X-direction low speed.So then as shown in Figure 4, while make stripper roll 340 central shaft 341 of stripper roll 340 be moved to a L from end points K around central shaft 341 rotations.At this moment, the end of diaphragm 2 along the outer peripheral face of stripper roll 340 by bonding and roll.Like this, the end of diaphragm 2 is peeled off down the length of stripper roll 340 peripheries about 3/4 from polarizer 1.
Phase III, shown in Fig. 5 arrow, linking part 330 moving axis 331 that rotates is rotated.Make the outer peripheral face of stripper roll 340 leave predetermined distance d like this from the surface of polarizer 1.At this moment, at the opposition side of the outer peripheral face of stripper roll 340, the back side, end that is wound on the diaphragm 2 on the stripper roll 340 is pressed against the whole contact site 352 of clamp portion 350.Like this, by stripper roll 340 and clamp portion 350 end of diaphragm 2 is clamped.At this moment, preferably make diaphragm stripping portion 300 integral body that rotate moving axis 331 of linking part 330 is rotated.Like this, just as shown in Figure 5, diaphragm 2 surpass stripper roll 340 central shaft 341 position L and be stripped to a M from polarizer 1.Therefore, be suppressed, so polarizer 1 can be by from 110 pull-ups of objective table portion at the tension force that stripper roll 340 diaphragm 2 when polarizer 1 leaves is produced.
The quadravalence section at first uses sensor 360 to judge as following whether diaphragm 2 is bonded on the outer peripheral face of stripper roll 340 and rolled-up.As shown in Figure 6, be bonded in well at diaphragm 2 under the situation of stripper roll 340 outer peripheral faces, the protected film 2 of the groove 342 (with reference to Fig. 1) that forms on the stripper roll 340 stops up.Therefore sensor 360 can not detect groove 342.On the other hand, be not bonded at diaphragm 2 under the situation of stripper roll 340 outer peripheral faces, the not protected film 2 of the groove 342 that forms on the stripper roll 340 stops up.Therefore sensor 360 can detect groove 342.Like this, can detect groove 342 according to sensor 360 and can judge whether diaphragm 2 is bonded in the outer peripheral face of stripper roll 340 and rolled-up.
When sensor 360 can not detect diaphragm 2, then make diaphragm stripping portion 300 turn back to the end points K of polarizer 1, from phase I repetitive operation once more.On the other hand; when sensor 360 can detect diaphragm 2; then as shown in Figure 6, making diaphragm stripping portion 300 leave predetermined distance from the surface of polarizer 1 makes diaphragm stripping portion 300 with at a high speed outside X-direction moves to objective table portion 110 (with reference to Fig. 1) unchangeably.Like this, the part of being stripped from the diaphragm 2 that roller 340 and clamp portion 350 clamp is by to the X-direction towing, and therefore, whole protecting film 2 is peeled off from polarizer 1.The diaphragm of being peeled off fully from polarizer 12 is sagging from stripper roll 340 as shown in Figure 7 like this.
Five-stage moves the portion 400 of removing as shown in Figure 7, and the end from the sagging diaphragm 2 of stripper roll 340 is placed between two bar-like members 410,420.And the interval that makes two bar-like members 410,420 narrows down and is adjacent to mutually, and an end of diaphragm 2 is fixed between them.
The 6th stage made diaphragm stripping portion 300 move to the rightabout of X-direction as shown in Figure 8, made stripper roll 340 away from the portion of removing 400.Like this, diaphragm 2 is removed portion's 400 towings, and finally, the part that is bonded in the diaphragm 2 on stripper roll 340 outer peripheral faces is just separated by the outer peripheral face from stripper roll 340.At this moment, the power of cylinder 320 towing linking parts 330 is died down, stripper roll 340 is rotated easily.
As above, the polaroid protective film of the embodiment of the invention is removed device by by stripper roll 340 and clamp portion 350 end of diaphragm 2 being clamped and towing and whole protecting film 2 is removed from polarizer 1.Therefore, it is different with conventional device that this removes device, do not need splicing tape.Therefore this to remove device more favourable than existing apparatus on the manufacturing cost that further reduces display unit, can improve the yield rate and the productivity of display unit.
Embodiments of the invention are not limited to the above embodiments.So long as those skilled in the art just can not break away from the technology of the present invention thought ground the foregoing description is carried out numerous variations enforcement.For example replace the two ends of supporting stripper roll 340, also the central authorities that can support stripper roll 340 by a linking part by a pair of linking part 330.This change also is interpreted as belonging to technical scope of the present invention certainly.
