Aligned units driving element 114c is used for aligned units 114 is flatly shifted to pressure attachment device 130.In other words, the panel and the aligned units 114 of accurately aiming at each other is moved to the polarization plates attachment position by driving element 114c.At polarization plates attachment position place,, preferably around panel, there is not large volume o components because polarization plates feeding mechanism 120 and pressure attachment device 130 insert (access to) panel.Therefore, in the present embodiment, the advancing of aligned units driving element 114c is stopped at the position away from the polarization plates attachment position.
Preferably, the aligned units 114 of present embodiment comprises that further panel promotes roller 114d, is used for panel is promoted to predetermined altitude.In other words, promote at panel under the operation of roller 114d, be delivered to the panel aligned position by panel transfer unit 112 and by means of panel stopper 112c after stopping at that position, panel promotes roller 114d and by the lower end that upwards promotes panel panel is promoted to predetermined altitude at panel.In the case, predetermined altitude is preferably approximate 10mm.When panel was aligned and is provided for pressure attachment device 130, panel promoted the lower end that roller 114d supports panel continuously.
Fig. 5 has illustrated the structure of polarization plates feeding mechanism 120.Polarization plates feeding mechanism 120 is designed to erect the polarization plates of the horizontal positioned that provides from external source, and after boundary belt is stripped from the upright polarization plates through erectting is delivered to predetermined polarization plates attachment position.In the present embodiment, polarization plates feeding mechanism 120 comprises: polarization plates absorbing unit 122, polarization plates are erect unit 124, horizontal drive unit 126 and tilting unit 128.Although not shown, boundary belt peel off device be placed on polarization plates feeding mechanism 120 near.
At this, be used to use the polarization plates absorbing unit 122 of the fastening polarization plates that provides from external source of vacuum adsorption force to be divided into leading section 122a and rearward end 122b.Rearward end 122b is suitable for applying vacuum adsorption force in the adjustable mode of intensity, and this is because when boundary belt is stripped from polarization plates, and rearward end 122b must be by putting on the high vacuum absorption affinity itself and fastening polarization plates.On the contrary, leading section 122a is suitable for only applying fixing low vacuum absorption affinity and is free to slide according to the rotation of pressure attachment device 130 after boundary belt is peeled off fully to allow polarization plates.Therefore, leading section 122a is not used in the process of peeling off boundary belt, and only is used for producing the dangerous required low vacuum absorption affinity that the polarization plates that will be attached to it offers pressure attachment device 130 and be not intended to separate.
Preferably, the rearward end 122b of present embodiment has been mounted rearward end CD-ROM drive motor 122c, is used for adhering to mobile rearward end 122b on the in-plane at panel to a certain extent.Rearward end CD-ROM drive motor 122c is suitable for accurately regulating the position of rearward end 122b.This allows polarization plates to be placed on the accurate protection band and peels off the position, and therefore enables suitably to peel off boundary belt.Preferably, in the present invention, the first controller (not shown) that is used for rearward end CD-ROM drive motor 122c is provided to rearward end 122b is placed on predetermined accurate location.
Polarization plates absorbing unit 122 is perforated a plurality of vacuum hole 122d of the preset distance that is spaced each other so that produce vacuum adsorption force.Should point out that polarization plates absorbing unit 122 of the present invention can be used to fastening various polarization plates with different size.This means that the vacuum suction intensity of force that is applied by rearward end 122b must adjust according to the different size of polarization plates.Related to this is that present embodiment discloses two kinds of methods that are used to control the vacuum suction intensity of force that is applied by rearward end 122b.
With reference to Fig. 6 of explanation first control mode, according to the size of polarization plates rearward end 122b is divided into several districts imaginaryly, thereby resulting dividing regions is controlled respectively to produce an amount of vacuum adsorption force.In an illustrated embodiment, rearward end 122b is divided into three imagination district A, B and C, vacuum adsorption force is only applied by district A under the situation of small scale panel thereby make, under the situation of mesoscale panel, apply, and under the situation of large scale panel, apply by whole district A, B and C by district A and B.Certainly, will be expressly understood that according to the different size of various polarization plates, the quantity and the shape in imagination district are variable.
Before explanation second control method, at first, under vacuum hole 122d, provide absorption affinity to stop 122e with reference to Fig. 7 of one of explanation vacuum hole 122d.Stop that but the 122e vertical moving is optionally to tackle the vacuum adsorption force of vacuum hole 122d.In other words, in the position that moves up, stop the vacuum adsorption force of 122e interception vacuum hole 122d, but in the position that moves down, it puts on polarization plates with the vacuum adsorption force of vacuum hole 122d.Such absorption affinity stops that 122e is driven by drive unit, and it only is operated when negative electricity and positive electricity are applied at that time simultaneously.As shown in Figure 8, negative electricity and positive electricity are imposed on the vacuum hole 122d that is set up with lattice respectively horizontally and vertically, all be applied at that time thereby make it only work as negative electricity and positive electricity, the 122e that stops that is installed under the vacuum hole 122d can be selectively driven.
The advantage that mode had that drives the selected latter who stops of vertical and the horizontally disposed 122e of stopping is that it can control vacuum hole 122d one by one, but the perhaps vacuum hole 122d of the predetermined quantity that on selected level or perpendicular line, is aligned of centralized control.Therefore, might be according to the size of polarization plates; Increase the applicability of the vacuum adsorption force that applies by vacuum hole 122d, thereby do not prevent that optionally to block some vacuum hole 122d that demonstrate leakage problematic vacuum hole 122d from stopping adsorption operations, when operating continuously, repair problematic vacuum hole, and control the vacuum suction intensity of force effectively by the vacuum adsorption force of optionally tackling the vacuum hole of during attach operation, selecting according to the transmission speed of polarization plates.
Interchangeablely be, as shown in Figure 9, polarization plates absorbing unit 122 can be modified so that it has the rearward end 122b ' littler than the rearward end 122b of the foregoing description, and rearward end 122b ' is removable must be away from the significant distance of leading section 122a.Certainly, the vacuum adsorption force that is applied by rearward end 122b ' is with the mode Be Controlled identical with above embodiment.In such alternative embodiment, at the beginning, leading section 122a is positioned at the far-end with the approaching polarization plates absorbing unit 122 of pressure attachment device 130, and rearward end 122b ' is positioned at predetermined boundary belt and peels off the position.Then, polarization plates is being attached in the process of panel, rearward end 122b ' is moved toward leading section 122a with the identical speed of speed of the polarization plates that caused with pressure attachment device 130.This has the effect that the polarization plates of preventing is separated with polarization plates absorbing unit 122.
In order to come mobile rearward end 122b ' with the speed identical with polarization plates, present embodiment discloses dual mode.
In disclosed first mode, rearward end 122b ' drives by the rearward end CD-ROM drive motor 122c such as servo motor.This allows speed and the position of rearward end 122b ' to be accurately controlled, thereby enables accurate polarization plates attach operation.In the case, when polarization plates was moved by pressure attachment device 130, rearward end 122b can follow polarization plates and move freely and need not CD-ROM drive motor 122c.Only rearward end 122b is returned to its original position so that need CD-ROM drive motor 122c when preparing new attach operation after attach operation is formerly finished.
In disclosed second mode, rearward end 122b ' is only shifted to leading section 122a passively.In other words, if polarization plates is moved by pressure attachment device 130, the rearward end 122b that is attached to polarization plates is moved with polarization plates accordingly.Yet when needing that after polarization plates is attached to panel fully rearward end 122b turned back to its original position, rearward end 122b ' preferably is pushed away from leading section 122a, as shown in Figure 10 under the operation of driving element 122c '.In the case, preferably accessory plate 122f is coupled in driving element 122c ' at one side place, and damper 122g is coupled in the opposite side of accessory plate 122f again so that the collision impact between release rearward end 122b ' and the accessory plate 122f.In such alternative embodiment, under the operation of driving element 122c ', the rearward end 122b ' that is attached to polarization plates is moved toward leading section 122a, and adhere to finish after, it is returned to its original position.In the case, accessory plate 122f moves approachingly with leading section 122a by driving element 122c ' in advance.Therefore, if rearward end 122b ' arrives accessory plate 122f, then accessory plate 122f stops and pushing back rearward end 122b ' so that it is turned back to original position.
