Embodiment
Detailed explanation and accompanying drawing will cover the theme and the feature of embodiments of the invention.
As shown in Figure 1, according to an embodiment, stand polarizing board connecting apparatus comprises that a Polarizer link block 100, Plate supplying module 200, a Polarizer supply module 300 and a panel send module 400.
Described Polarizer link block 100 connects a Polarizer simultaneously on the left and right surfaces with the LCD panel of upright state supply.
Described Polarizer link block 100 is configured to comprise that one connects cylinder 110, a Polarizer feed unit 120 and a diaphragm and peels off unit 130.Connect cylinder 110 and on two surfaces of LCD panel, connect Polarizer.As shown in Figure 2, connection cylinder 110 is arranged to two cylindrical rollers settings and is arranged in parallel, and the periphery of two cylinders contacts on corresponding to the center line by the LCD of Polarizer feed unit 120 transmission one, and a fixed-size power applies making on the two cylinders direction respect to one another.Thereby a predetermined pressure is applied to two and connects on the particular element of passing through between the cylinder.At this moment, two connection cylinders are arranged to the distance variable between two cylinders, thereby make particular element can pass the two.One pressure feeding unit (figure do not show) also is arranged on two and connects between the cylinders, be used for by a flexible member to two cylinders apply one toward each other, fixed-size pressure.Described pressure feeding unit is arranged to and is connected cylinder 110 and connects respectively, and, make a fixed-size pressure always be applied on the surface in contact of described upper and lower connection cylinder 110 by making connection cylinder 110 push away connection cylinder 110 on the direction toward each other.
In an embodiment, a LCD panel (L) and a Polarizer (P) pass through between described connection cylinder 110, thereby Polarizer (P) is connected to the LCD panel because of connecting cylinder 110 applied pressures.At this moment, when LCD panel and Polarizer connecting between the cylinder 110 by the time, even connect variable in distance between the cylinder 110, described pressure feeding unit always applies a fixed-size pressure connecting between the cylinder 110.
Simultaneously, Polarizer (P) is wound up under the state that connects cylinder 110 peripheries mobile at the Polarizer of feeding.Thereby because Polarizer self has high resiliency, when connection cylinder 110 dragged Polarizer (P), Polarizer (P) limit curved edges was wound up into and connects on the cylinder 110.Thereby Polarizer is being connected on the LCD panel simultaneously to be wound up into the state rotation that connects on the cylinder 110.
Therefore, in an embodiment, a Polarizer absorbing unit 112 is set further, make be fed into the Polarizer (P) that connects cylinder 110 keep being wound up into connect cylinder 110 and not with state that it separates in rotation.Polarizer absorbing unit 112 uses vacuum adsorption force Polarizer (P) to be adsorbed on the periphery that connects cylinder 110.Therefore, Polarizer absorbing unit 112 comprises by penetrate adsorption hole that the periphery that connects cylinder 110 forms and the asepwirator pump (scheming not show) by the adsorption hole suction air on thickness direction.As shown in Figure 3, described connection cylinder 110 is provided with the asepwirator pump that is used for suction air, has the hollow round column structure and is connected with the inner space, thereby can produce absorption affinity by the adsorption hole suction air.At this moment, in an embodiment, absorption affinity is adjusted in expectation corresponding to Polarizer makes it be lower than bounding force between LCD and the Polarizer, because Polarizer (P) is connected to LCD panel (L) afterwards, must separates rather than separate from the LCD panel from connecting cylinder 110.
Then, Polarizer feed unit 120 feeding Polarizers (P) and Polarizer is wound up into respectively connect the periphery of cylinder 110.As shown in Figure 2, Polarizer feed unit 120 is separately positioned on the rear of described connection cylinder.Polarizer feed unit 120 comprises a supply roll 122 and a Polarizer feeding adsorption plate 124.As shown in Figure 2, supply roll 122 is arranged in and connects cylinder 110 rears, and comprises the internal cylinder 122b and an external roller 122a of upper and lower cylinder, and described inside and outside cylinder is flatly inside and outside to be arranged.Supply roll 122 transmits the Polarizer (P) between internal cylinder 122b and external roller 122a and Polarizer (P) is moved in connection cylinder 110 peripheral direction.At this moment, as shown in Figure 2, the external roller 122a in the described supply roll is arranged to and can inside and outsidely moves.Thereby, when Polarizer (P) when loading for the first time, external roller 122a outwards moves and forms one than large-spacing between supply roll 122, thereby makes the front end of the Polarizer (P) that moved by Polarizer feeding adsorption plate 124 can easily enter between the described supply roll 122.After this, after the front end of Polarizer entered between the supply roll 122, external roller 122a moved inward and engages reliably and the fixing front end of Polarizer.Then, supply roll 122 rotates and carrying out feeding work when the peripheral direction that connects cylinder 110 moves Polarizer (P).
Further, as shown in Figure 2, Polarizer feeding adsorption plate 124 is arranged on supply roll 122 rears, and the states that absorption is vertically risen by Polarizer mobile unit 370 are a side of the Polarizer of supply down, and the front end of the Polarizer of absorption is delivered between the supply roll 122.Therefore, Polarizer feeding adsorption plate 124 is formed with many adsorption holes and holds Polarizer by vacuum adsorption force on its whole surface.Further, Polarizer feeding adsorption plate 124 is arranged to and can be moved horizontally along the direction of Polarizer supply roll 122, and the front end of Polarizer is delivered between the supply roll 122, thus the feeding Polarizer.Simultaneously, in order easily the front end of Polarizer to be delivered between the supply roll 122, expectation is when being adsorbed onto Polarizer feeding adsorption plate 124, and the front end of Polarizer is adsorbed in the mode of giving prominence to forward and expose.
Further, as shown in Figure 2, Polarizer feed unit 120 touches the periphery that connects cylinder 110, and preferably comprises a bonding cylinder 126, is used for a side of the Polarizer (P) of supply roll 122 feedings is adhered to the periphery that connects cylinder 110.When the front end of Polarizer (P) by supply roll 122 during in the peripheral direction feeding, the absorption affinity that produces owing to the Polarizer absorbing unit 112 that connects cylinder 110 makes Polarizer (P) be adsorbed onto the periphery that connects cylinder 110.Yet, for the front end that makes Polarizer (P) can be adsorbed onto the exact position that connects cylinder 110 along correct direction, bonding cylinder 126 is arranged to connect in the contact of described supply roll 122 the place aheads the state of the periphery of cylinder 110, thereby Polarizer (P) is adhered to the periphery that connects cylinder 110.In order in the process that after this connects LCD panel and Polarizer, accurately to be connected the LCD panel, Polarizer (P) need be adsorbed onto the exact position that connects cylinder 110.
Next, diaphragm is peeled off unit 130 and is peeled off and be connected to the lip-deep diaphragm of Polarizer (P).Side applying adhesive at Polarizer (P) is used for adhering to definitely the LCD panel.Thereby in order to protect the surface that is covered with bonding agent on it, diaphragm is connected to the one side that is covered with bonding agent on the Polarizer (P).For Polarizer (P) is connected on the LCD panel, must peel off diaphragm, like this, diaphragm is peeled off unit 130 and is removed described diaphragm.In an embodiment, diaphragm is peeled off unit 130 use adhesive strips and is peeled off diaphragm from being attached to the Polarizer (P) that connects cylinder 110.Therefore, as shown in Figure 2, diaphragm is peeled off unit 130 and is arranged in abutting connection with connecting cylinder 110, and comprises and peel off a cylinder 132 and an adhesive strip circular drum 134.Peel off cylinder 132 and be arranged to contact with the periphery that is connected cylinder 110, and by being wound up into the state backspin of its periphery at adhesive strip (T) then peel off diaphragm.Further, as shown in Figure 2, adhesive strip circular drum 134 is arranged to make two cylinders separate to place with predetermined space, and when adhesive strip (T) during from a roller shifting to another cylinder, make adhesive strip on mobile route by peeling off cylinder 132.Thereby, expect that adhesive strip circular drum 134 comprises one and self also passed through to drive this head roll and the driven cylinder of passive rotation by head roll and the described adhesive strip of supply that a driving arrangement (figure does not show) drives.
Further, in an embodiment, be desirably in diaphragm and peel off and a diaphragm also is set on the unit 130 removes the unit.Diaphragm is removed the unit and is arranged to also remove the diaphragm of having peeled off that is connected to adhesive strip (T) in abutting connection with adhesive strip circular drum 134.Thereby as illustrated in fig. 1 and 2, on the mobile alignment of adhesive strip (T), a diaphragm is removed auxiliary cylinder and further is formed on the bonding and mobile route of the diaphragm peeled off, thereby makes the front end of the diaphragm that is connected to adhesive strip (T) outstanding.Further, a diaphragm is set removes tongue bars, be used to pick up diaphragm and a delivery cassette that provides especially (figure does not show) is provided for the front end of diaphragm.Thereby, as illustrated in fig. 1 and 2, diaphragm remove tongue bars be arranged to can before and after ground move horizontally, move forward and pick up the front end of diaphragm, separate and the discharge diaphragm from adhesive strip (T).Then, diaphragm removal tongue bars moves backward and carries out next work, thereby removes next diaphragm.At this moment, cylinder is associated with a linear guide rail and moves in the above and be used to carry out the rectilinear motion that diaphragm is removed tongue bars.
After this, Polarizer supply module 300 is separately positioned on Polarizer link block 100 left sides and right side, and on Polarizer link block left side and right side respectively polarizing board supply be used for being connected.Polarizer supply module 300 comprises that a Polarizer separates a feeding unit 310 and a Polarizer mobile unit 370.Polarizer separation feeding unit 310 separates and mobile a plurality of stacked Polarizers one by one.Further, Polarizer mobile unit 370 will separate that feeding unit 310 separates and the Polarizer that moves moves to a side of Polarizer link block 100 by Polarizer.
Polarizer separates feeding unit 310 and separates Polarizer one by one, and the Polarizer that separates to the polarizing board connecting apparatus supply.As shown in Figure 6, Polarizer separates feeding unit 310 and comprises a Polarizer separation supply roller 312, a Polarizer scotch 314 and a Polarizer stop cylinder 316.
Polarizer separates supply roller 312 and is separated with the lower floor Polarizer and supplied this superiors' Polarizer by the superiors' Polarizer in the Polarizer of Polarizer lifting unit 320 liftings a plurality of.Thereby as illustrated in Figures 5 and 6, it is a cylindrical roller structure that Polarizer separates supply roller 312, and forms by a specified power source and rotate.Further, the expectation Polarizer separates the periphery of supply roller 312 and is made up of a kind of material, and when described periphery touched Polarizer (P), the friction force of this material production was bigger.Because Polarizer separates supply roller 312 and separates and mobile Polarizer when rotating, thus if friction force is low during the contact Polarizer, then can not by make Polarizer easily from a roller separation make Polarizer separation and move and steadily carry out.As shown in Figure 6, Polarizer separates supply roller 312 rotating with the upper end state of contact of a plurality of stacked Polarizers, so its upper surface with the Polarizer of the superiors contacts.Therefore, Polarizer separates the only Polarizer of the mobile the superiors of supply roller 312.
Simultaneously, in an embodiment, Polarizer separates supply roller 312 can be arranged to supply the Polarizer of multiple standards.Thereby what Polarizer separated supply roller 312 is shorter in length than Polarizer and Polarizer stop cylinder 316, and corresponding to changing the position to carry out an operation as the size of the Polarizer of target.Therefore, as shown in Figure 7, in an embodiment, Polarizer separation supply roller 312 is arranged to along continuous straight runs and can be moved up and down.In order to change the position that Polarizer separates supply roller 312, Polarizer separation supply roller 312 at first moves to the top and separates with Polarizer stop cylinder 316 and analog.Further, Polarizer separates supply roller 312 along continuous straight runs and moves and arrive an expectation position, and descends once more and contact with Polarizer stop cylinder 316.
Further, Polarizer scotch 314 is arranged on the downside that Polarizer separates supply roller 312, and the Polarizer except that the superiors is moved by Polarizer separation supply roller 312 in the prevention Polarizer.Therefore, in an embodiment, expectation Polarizer scotch 314 is arranged to separate supply roller 312 with Polarizer and is separated placement with a predetermined space, and the interval between the two is roughly the thickness of a Polarizer.In other words, expect that being spaced apart of described cylinder 312 and described scotch 314 can not pass through two Polarizers by a Polarizer.
When Polarizer separation supply roller 312 once moved two or more Polarizer, Polarizer stop cylinder 316 stoped two or more Polarizers of lower floors to move.Thereby as shown in Figure 6, Polarizer stop cylinder 316 is arranged on the rear of Polarizer scotch 314, thus when moving two Polarizers if stoped by many Polarizers scotch 314, it separates Polarizer once more.The periphery that Polarizer stop cylinder 316 is arranged to separate with Polarizer supply roller 312 contacts.Further, Polarizer stop cylinder 316 forms a rotating cylinder, but rotates greater than fixed-size power by applying one.In other words, because described cylinder is rotatable and self have some spline power, the structure of described cylinder to be arranged to and can to rotate greater than the power of spline power by applying one.Therefore, Polarizer stop cylinder 316 is configured to driven cylinder, and it separates supply roller 312 and contacts with Polarizer, thereby separates supply roller 312 and rotate by rotating Polarizer.At this moment, in an embodiment, because Polarizer stop cylinder 316 separates one of two bonding and mobile Polarizers, and prevent that two Polarizers from moving together, Polarizer stop cylinder 316 is configured to and can rotates greater than the power of the bounding force between two Polarizers by applying one.Thereby when two Polarizers moved with stacked state, because Polarizer stop cylinder 316 do not rotate, two Polarizers Polarizer at the middle and upper levels separated supply roller 312 by Polarizer and moves, and the Polarizer of lower floor be can't help Polarizer stop cylinder 316 and moved.Thereby with stacked Polarizer separation.On the other hand, when moving a Polarizer, this Polarizer normally moves, and rotates because Polarizer stop cylinder 316 separates supply roller 312 by Polarizer.
Further, Polarizer supply module 300 also comprises a Polarizer lifting unit 320.All Polarizers that 320 liftings wherein a plurality of Polarizers in Polarizer lifting unit are stacked, the periphery that makes the Polarizer of the superiors separate supply roller 312 with Polarizer contacts.Thereby Polarizer lifting unit 320 comprises a size and the similar slab 322 of Polarizer and passes through to promote slab 322 and the motor 324 of lifting Polarizer.Expectation motor 324 can accurate be controlled.For example can use a servo motor.Thereby, lifting slab 322 by CD-ROM drive motor 324.Further, during Polarizer above Polarizer separates supply roller 312 supplies, must separate supply roller 312 with Polarizer during the continuous lifting of other Polarizer and contact.Thereby motor 324 is configured to apply a fixed-size power that makes progress and promotes Polarizer upwards.
Shown in Figure 4 and 5, expectation Polarizer supply module 300 also comprises an air injection unit 330.Air injection unit 330 is by helping to separate stacked Polarizer from a plurality of stacked Polarizer one side direction Polarizer direction injection airs.A plurality of stacked Polarizers closely are adhered on the adjacent Polarizer because of the weight of himself.Thereby, the Polarizer of the superiors must be separated with the Polarizer of lower floor, thereby separate and supply the Polarizer of the superiors one by one.As shown in Figure 8, air injection unit 330 injection air and separate Polarizer between the Polarizer of the superiors and lower floor's Polarizer.As shown in Figure 4, in an embodiment, it is contour that a plurality of air injection units 330 are arranged to separate with Polarizer supply roller 312.
As shown in Figure 9, according in the Polarizer supply module 300 of the present invention, a plurality of Polarizers are placed in the Polarizer box (C) stackedly or need not Polarizer box (C) and load a plurality of Polarizers.When using Polarizer box (C), many Polarizers (P) stacked on top of one another, the fixing Polarizer (P) of number is placed in the Polarizer box (C), and loads Polarizer (P) by mobile Polarizer box (C).Expectation Polarizer supply module 300 further comprises a Polarizer kit supply unit 340, is used for from lateral Polarizer supply module 300 polarizing board supply boxes (C).In an embodiment, shown in Figure 4 and 5, Polarizer kit supply unit 340 is configured to a plurality of cylinders and places with a predetermined space horizontal subdivision.The Polarizer box (C) that is placed on upside moves when cylinder rotates.
Then, an end that is desirably in Polarizer kit supply unit 340 further is provided with a Polarizer box anchorage clip (figure does not show) that is used for fixing mobile Polarizer box.In the process of separating supply, must fix and move to the Polarizer box (C) of a final working position and it can not moved by Polarizer kit supply unit 340.Thereby Polarizer box anchorage clip is fixed this Polarizer box by being connected with the Polarizer box downside multiple spot that arrives final working position.
Further, Polarizer supply module 300 also comprises a Polarizer detecting unit 350, is used to detect by Polarizer separate the polarisation plate number that feeding unit 310 separates and supplies.As shown in Figure 5, Polarizer detecting unit 350 is arranged on that Polarizer separates feeding unit 310 the place aheads and final the detection separated by Polarizer that feeding unit 310 separates and whether the polarisation plate number of supply is 2.
Further, in an embodiment, when Polarizer detecting unit 350 detects two or more Polarizer, a control module (figure does not show) further is set, be used to receive the detection signal of Polarizer detecting unit 350 and separate supply roller 312 by the counter-rotating Polarizer and return Polarizer.Occur in owing to a Polarizer detachment process wrongly when having supplied two or more Polarizer, carry out the Polarizer mask work once more thereby described control module separates supply roller by the described Polarizer that reverses.Therefore, in the Polarizer supply module 300 of the foundation embodiment of the invention, thoroughly avoided occurring the possibility of the mistake of the bonding and supply of two or more Polarizers.
Further, Polarizer supply module 300 also comprises a cleaning unit 360.Shown in Figure 4 and 5, cleaning unit 360 is arranged on Polarizer detecting unit 350 the place aheads, is used for cleaning by Polarizer separating the Polarizer that feeding unit 310 separates and supplies.In an embodiment, contact with each other and when rotating, cleaning unit 360 is removed the lip-deep impurity of Polarizers when two cylinders.
The upper surface that is placed on the Polarizer on Polarizer alignment unit 380 upper surfaces therein be adsorbed and fixing state under, Polarizer mobile unit 370 by moving horizontally to Polarizer feeding adsorption plate 124 polarizing board supplies.Polarizer mobile unit 370 be arranged to can be under the state that Polarizer is adsorbed the absorption mobile robot of mobile Polarizer.Shown in Figure 10 a, Polarizer mobile unit 370 adsorbs the upper surface of Polarizer (P) and it is made progress lifting shown in Figure 10 b.Further, shown in Figure 10 c, Polarizer mobile unit 370 moves horizontally towards Polarizer feeding adsorption plate 124.At this moment, Polarizer mobile unit 370 is near Polarizer feeding adsorption plate 124, and maintenance can be rotated Polarizer the interval of 90 degree.After Polarizer mobile unit 370 was near Polarizer feeding adsorption plate 124, the Polarizer of Polarizer mobile unit 370 rotation horizontalitys was holded up it.After this, shown in Figure 10 d, Polarizer mobile unit 370 moves horizontally and Polarizer is sent to Polarizer feeding adsorption plate 124.
