Embodiment
Detailed explanation and accompanying drawing will cover the theme and the feature of embodiments of the invention.
According to an embodiment, as shown in Figure 1, polarizing board connecting apparatus comprises a Polarizer link block 100, Plate supplying module 200, a Polarizer supply module 300 and a panel release module 400.
At first, described Polarizer link block 100 is elements that are used for connecting simultaneously a Polarizer on the upper and lower surface of LCD panel, and wherein each plate level is placed.
According to embodiment, described Polarizer link block 100 comprises that one connects cylinder 110, a Polarizer feed unit 120 and a diaphragm and peels off unit 130.At first, described connection cylinder is an element that is used for connecting Polarizer on the upper and lower surface of LCD panel.As shown in Figure 2, described connection cylinder 110 is arranged to two cylindrical rollers and is arranged in parallel up and down, and the periphery contact of two cylinders applies a size and fixes, makes two cylinders power respect to one another on it.Thereby a predetermined pressure is applied to the particular element of passing through between two cylinders.At this moment, two cylinders are arranged to the distance variable between two cylinders, thereby particular element can be passed through.One pressure feeding unit (figure does not show) also is arranged between two cylinders, thereby applies a fixed-size pressure, wherein, utilizes a flexible member to make two cylinders be subjected to a fixed-size pressure in direction respect to one another.Described pressure feeding unit is arranged to connect respectively with the described upper and lower that is connected cylinder 110.Described pressure feeding unit is also always by pushing away described connection cylinder 110 along direction toward each other, thereby the surface in contact that connects cylinder 110 in described upper and lower applies a fixed pressure.
In an embodiment, LCD panel (L) and Polarizer (P) make Polarizer (P) be connected on the LCD panel by between the described connection cylinder 110 because of connecting cylinder 110 applied pressures.At this moment, when LCD panel and Polarizer between described connection cylinder 110 by the time, even the variable in distance of described connection cylinder 110 upper and lowers, described pressure feeding unit always applies a fixed pressure between described connection cylinder 110.
Simultaneously, a feeding Polarizer (P) moves in described connection cylinder 110 peripheries with reeling condition.Because Polarizer self has high resiliency, when described connection cylinder 110 dragged Polarizer (P), Polarizer limit curved edges was wound up on the described connection cylinder 110.Thereby in an embodiment, Polarizer is wound on to be wound up into state when rotation on the described connection cylinder 110, and Polarizer just is connected to the LCD panel.
Therefore, in an embodiment, a Polarizer absorbing unit is set further so that Polarizer (P) keeping being wound up into described connection cylinder 110 not with when it separates, can be fed into the connection cylinder 110 of described rotation.Described Polarizer absorbing unit 112 uses vacuum adsorption force Polarizer (P) to be adsorbed on the periphery of described connection cylinder 110.Therefore, in an embodiment, described Polarizer absorbing unit 112 comprises an adsorption hole 112a and an asepwirator pump by adsorption hole 112a suction air (figure does not show) that forms by the perimeter thicknesses direction that penetrates described connection cylinder 110.As shown in Figure 3, described connection cylinder 110 is provided with the asepwirator pump that is used for suction air, is connected by the hollow round column structure and with the inner space, thereby can produces absorption affinity by adsorption hole 112a suction air.At this moment, 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, is to separate and do not separate from the LCD panel from described connection cylinder 110.
Described Polarizer feed unit 120 is elements that are used for feeding Polarizer (P), thereby makes Polarizer be wound up into the periphery that described upper and lower connects cylinder 110 respectively.As shown in Figure 2, described Polarizer feed unit 120 is separately positioned on last the place ahead that described top connects cylinder is connected cylinder with described bottom inferoanterior.Described Polarizer feed unit 120 comprises a supply roll 122 and Polarizer arrangement cylinder 124.As shown in Figure 2, described supply roll 122 is arranged in and connects cylinder 110 outsides, and form by the upper and lower cylinder, described upper and lower cylinder flatly is arranged above and below, thereby by the Polarizer (P) of transmission between up-down roller 122 Polarizer (P) is moved along described connection cylinder peripheral direction.At this moment, as shown in Figure 2, the upper cylinder in the described supply roll is arranged to and can be moved up and down.Thereby when Polarizer (P) when loading for the first time, by moving up, upper cylinder forms one than large-spacing between supply roll, makes the front end of the Polarizer (P) that moved by Polarizer supply module 300 can easily enter between the described supply roll 122.Then, after the front end of Polarizer (P) entered between the described supply roll 122, upper cylinder descended and engages reliably and the fixing front end of Polarizer (P).After this, described supply roll 122 rotates and carry out feeding work along the circumferential mobile Polarizer (P) of described connection cylinder 110 time.In addition, as shown in Figure 2, Polarizer settles cylinder 124 to be arranged on the inferoanterior of described supply roll 122, and is configured to separate a plurality of cylinders of placement with a predetermined space, makes the Polarizer of being supplied by Polarizer supply module 300 (P) to be placed on the top.
Further, as shown in Figure 2, described Polarizer feed unit 120 is arranged to touch the periphery that connects cylinder 110.Preferably, described Polarizer feed unit 120 further comprises a viscosity cylinder 126, is used for the side by the Polarizer (P) of described supply roll 122 feedings is adhered to the periphery that connects cylinder 110.When the front end of Polarizer (P) was fed into the periphery that connects cylinder 110 by supply roll 122, the absorption affinity that produces owing to the Polarizer absorbing unit 112 that connects cylinder 110 made Polarizer (P) be adsorbed onto the periphery that connects cylinder 110.Yet above-mentioned viscosity cylinder 126 is arranged in described supply roll 122 the place aheads and the periphery contact that is connected cylinder 110, makes the front end of Polarizer (P) to be adsorbed onto the exact position that connects cylinder 110 along correct direction.Thereby Polarizer (P) can adhere to the periphery that connects cylinder 110.
Next, diaphragm is peeled off unit 130 and is used to peel off and is connected to the lip-deep diaphragm of Polarizer (P).One side of Polarizer (P) adheres to the LCD panel definitely by the bonding agent that is applied on it.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.Diaphragm is peeled off unit 130 and is used an adhesive strip to peel off diaphragm from being adsorbed onto the Polarizer (P) that connects cylinder 110.Therefore, 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.Peeling off cylinder 132 is arranged to contact with the periphery that is connected cylinder 110 and be wound up into the state rotation of its periphery and peel off diaphragm with adhesive strip (T).Further, 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, described cylinder 134 transmits described adhesive strip by peeling off cylinder 132 along a mobile alignment.Thereby expectation adhesive strip circular drum 134 comprises the head roll and a described adhesive strip of supply and the driven cylinder of passive rotation by driving this head roll that are driven by a driving arrangement (figure does not show).
After this, described Polarizer supply module is set to the multilayer Polarizer supply module of a stacked on top of one another.Further, the described Polarizer supply module on upper strata is set to connect the cylinder polarizing board supply to top, and the described Polarizer supply module of lower floor is set to connect the cylinder polarizing board supply to the bottom.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 be separated that feeding unit 310 separates and the Polarizer that moves moves to 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 that a Polarizer separates supply roller 312, Polarizer scotch 314 and the cylinder of Polarizer stop more than one 316 more than one.
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 in an embodiment, as illustrated in Figures 5 and 6, it is a cylindrical roller structure that Polarizer separates supply roller 312, and is rotated by an independent power source.Preferably, Polarizer separates the periphery of supply roller 312 and is made up of a kind of material, when described periphery touches Polarizer (P), the friction force of this material production is bigger, because Polarizer separates supply roller 312 and separates and mobile Polarizer when rotating, thereby if contact during Polarizer friction force low, then can not by make Polarizer easily from a roller separation make Polarizer separation and move and steadily carry out.In an embodiment, as shown in Figure 6, because Polarizer separates supply roller 312 to rotate with the upper end state of contact of a plurality of stacked Polarizers, its upper surface with the Polarizer of the superiors contacts.Therefore, Polarizer separation supply roller 312 moves the Polarizer of the superiors.
Simultaneously, Polarizer separates the Polarizer that supply roller 312 can be arranged to provide multiple standards.Thereby as shown in Figure 7, what Polarizer separated supply roller 312 is shorter in length than Polarizer and many Polarizers 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, Polarizer separates supply roller 312 to be arranged to and can to move up and down, and is in horizontal direction.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 many Polarizers stop cylinder 316 and analog.Further, Polarizer separates supply roller 312 along continuous straight runs and moves and arrive an expectation position.And descend once more and contact with many Polarizers stop cylinder 316.
Further, many Polarizers 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.Preferably, many Polarizers 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 described cylinder 312 and described scotch 314 be arranged to it and at interval can not pass through two Polarizers by a Polarizer.
Further, when Polarizer separation supply roller 312 once moved two or more Polarizer, Polarizer stop cylinder 316 can prevent that lower floor's Polarizer from moving.Thereby as shown in Figure 6, Polarizer stop cylinder 316 is arranged on the rear of many Polarizers scotch 314, thus when moving two Polarizers if stoped by many Polarizers scotch 314, it separates Polarizer once more.In an embodiment, Polarizer stop cylinder 316 periphery of being 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, but some spline power is arranged himself, the structure of described cylinder is arranged to and can be rotated 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, and separates supply roller 312 and rotate by rotating Polarizer.At this moment, because Polarizer stop cylinder 316 separates one of two bonding and mobile Polarizers, and stop the Polarizer that separates to move, 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 contrary, 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.The periphery that 320 liftings a plurality of stacked Polarizers in Polarizer lifting unit make 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, when Polarizer separates supply roller 312 from the upside polarizing board supply, must separate supply roller 312 with Polarizer during the continuous lifting of other Polarizer and contact.Thereby motor 324 promotes Polarizer and upwards applies a fixed-size power that makes progress.
Then, shown in Figure 4 and 5, Polarizer supply module 300 also comprises an air injection unit 330.Air injection unit 330 separates 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 help the Polarizer of the superiors is separated with the Polarizer of lower floor between the Polarizer of the Polarizer of the superiors and lower floor.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.
Further, as shown in Figure 9, in foundation 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 the stacked placement of a plurality of Polarizer.When using Polarizer box (C), a plurality of Polarizers (P) stacked on top of one another, the definite Polarizer (P) of number of packages is loaded in the Polarizer box (C) then, then, loads Polarizer (P) by mobile Polarizer box (C).Therefore, 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).Shown in Figure 4 and 5, in an embodiment, 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.The Polarizer box (C) that is moved to a final working position by Polarizer kit supply unit 340 must be fixed in the process of separating supply and it can not moved.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,, expect a Polarizer detecting unit 350 further is set, be used to detect and separate the polarisation plate number that feeding unit 310 separates and supplies by Polarizer according in the Polarizer supply module 300 of the present invention.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 testing results when having supplied two or more Polarizer, expectation further is provided with a control module (figure does not show), is used to receive the detection signal of Polarizer detecting unit 350 and separate supply roller 312 by the counter-rotating Polarizer and return Polarizer.When a mistake that occurs in owing to a Polarizer detachment process has been supplied two or more Polarizer, thereby described control module separates supply roller and carries out the Polarizer mask work once more because of the rub-out signal described Polarizer that reverses.Therefore, according in the Polarizer supply module 300 of the present invention, thoroughly avoided occurring the possibility of the mistake of the bonding and supply of two or more Polarizers.
Further, according to the present invention, 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 and cleaning is separated the Polarizer that feeding unit 310 separates and supplies by Polarizer.When two cylinders are rotating when contacting with each other, cleaning unit 360 is removed the lip-deep impurity of Polarizers.
