The present invention relates to a polarizing film bonding apparatus, and more particularly, to a polarizing film bonded to a substrate module for a flat panel display device to form a polarizing layer, in particular, to remove, clean and bond foreign substances for forming the polarizing layer. The present invention relates to a polarizing film bonding apparatus in which a series of operations such that the substrate module is interposed therebetween corresponds to both sides of the module and has a same transfer pitch and is moved in a two-sided manner of approaching or vice versa.

In general, a substrate module for a flat panel display device is made through a common process of combining two sheets of substrates facing each other with spacers therebetween, and for polarizing incident light on both sides of the substrate module. The polarizing layers are formed, respectively.

As a method of forming the polarizing layer, a method of bonding a conventional polarized film having a thickness in the range of approximately 10 μm to 40 μm to both surfaces of the module is widely known. The method proceeds in a cross-sectional bonding manner in which the polarizing film is bonded in correspondence with any one surface facing upward while the substrate module is horizontally loaded on the loading stage.

This cross-sectional bonding method has a problem in that the work is complicated and excessive work time is required because the two stages of loading and unloading are performed so that both surfaces of the substrate module face upward on the loading stage.

As such, a bonding device that compensates for the shortcomings of the cross-sectional bonding method is Utility Model Registration No. 0351388 filed and registered on March 10, 2004 by the present applicant. The device loads the substrate module in a vertical position and allows a series of operations such as foreign material removal and bonding to be performed in a double-sided manner in response to both surfaces with the substrate module sandwiched therebetween.

However, the above-described polarizing film bonding apparatus according to the prior art, each of the pair of blades and the cleaning pad and each side surface of the module while moving in close or opposite directions to each other by the rotational movement with the substrate module in between Since the position changes in a state where contact is possible, it is difficult to adjust the position to an appropriate contact state according to the thickness of the substrate module.

In particular, in the manner in which the position is changed by the rotational movement as described above, since it is difficult to control the movement pitch of the pair of blades or the cleaning pads positioned with the substrate module therebetween, their positional deviation frequently occurs. There is a problem. As such, when the position deviation occurs, the work proceeds in a state in which contact pressures of different sizes are applied to both surfaces of the substrate module, so that it is difficult to obtain uniform double-sided work quality.

In addition, the method of changing the position by the rotational motion as described above, because the excessive contact pressure is transmitted by inertial force or the like when each blade and the cleaning pad is in close proximity to each other and contact with both surfaces of the substrate module may cause scratches on the surface. In addition, the physical properties of the substrate module may be deteriorated due to shock or vibration, thereby causing a defect quality.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to polarize in a two-sided work method in which uniform working conditions are maintained corresponding to both surfaces with a substrate module for a flat panel display device interposed therebetween.

The film bonding unit 26 bonds the polarizing film F to both sides of the module G while undergoing the following process.

First, the two bonding heads H3 on which the polarizing film F carried by the film transfer plate 36 from the cassette 34 are adsorbed are rotated by the rotation driving source 32 as shown in FIG. 9. After the change, when the rollers move in this state as shown in FIG. 10, the pressing rollers 30 are rolled in contact with both surfaces of the module G with the polarizing film F therebetween. The polarizing film F is pressed on the outer circumferential surface of 30 at the same time, and is simultaneously bonded to both sides of the module G, as shown in the drawing.

The film bonding part 26 has the two film transfer plates 36 in a state in which the two transfer adhesive tapes T are connected between the supply reel R3 and the recovery reel R4. It may further comprise a winding means 42 to be supplied and recovered at a uniform feed pitch.

As shown in FIG. 11, the winding means 42 includes two grounding rollers 44 and pressurization holes 46 for pressing one side of the outer circumferential surface of the grounding rollers 44, and the grounding rollers ( 44 and the pressing opening 46 are located on the winding plate 48 movably installed in the carrying plate 38.

The winding plate 48 is moved in position by the pneumatic transfer cylinder 50 in the transport plate 38 is changed to enable the winding operation.

The grounding roller 44 is positioned in the winding plate 48 so as to correspond to one side of the connection section of each adhesive tape T so that the tapes T may pass through the winding rollers 48.

In addition, the pressurization hole 46 is formed between the two grounding rollers 44 and the ground groove portion 52 for contacting one side of the outer circumferential surface of the rollers 44, respectively, the conventional pneumatic transfer cylinder ( The position of the ground groove 52 is changed by 54 so as to be in contact with one side of the outer circumferential surface of each ground roller 44.

To be supplied to the side. Then, the adhesive tape T pulled at a constant pitch by the above operation is recovered while being wound on the reel R4 side after the pressing operation of the pressing hole 46 is released.

Such a structure is, for example, when the adhesive tape T is supplied to the film transfer plate 36 side, for example, a deviation in the transfer pitch of the two adhesive tapes T occurs, thereby transferring the two films. Irregularly supplied to the plate 36 side can be prevented. In particular, when the two adhesive tapes (T) are moved at an irregular feed pitch, a positional deviation occurs when the polarizing film (F) attached to the two tapes (T) is adsorbed on the two bonding heads (H3). This may be a factor that degrades precision.

Meanwhile, the heads H1, H2, and H3 of the first foreign matter removing unit 16, the second foreign matter removing unit 20, and the film bonding unit 26 are transported in the same manner with the module G interposed therebetween. The position is changed by the position converting means 56 to allow two-sided contact for removing foreign matter and bonding while having a pitch and moving in proximity to or opposite to each other.

To this end, in the present embodiment, as shown in the drawing, using the screw C formed by dividing the left screw portion C1 and the right screw portion C2 as shown in FIGS. 13 to 15, Connect between the moving blocks (B1, B2, B3) facing the left and right screw coupling, and when the one end of the screw (C) receives the rotational force from the motor (M4) axis to rotate forward and reverse, Each of the moving blocks B1, B2, B3 facing each other by C1, C2 has the same feed pitch with the module G therebetween and is moved close to or opposite to each other.

The screw (C) is formed in a length range that can be connected to each other by a screw coupling corresponding to the interval of each of the moving blocks (B1, B2, B3) facing each other, the two threads (C1, C2) are threaded It is made at the same pitch interval.

The screw C may be a conventional ball screw (ball screw) can be used. This ball screw can minimize the friction generated in the screw coupling portion during rotation, and in particular, because of the excellent conveying precision, it is widely used as a conveying shaft of various precision devices and devices.

The shaft of the motor M4 is connected to the one end of the screw C by a coupling to enable power transmission, and each of the opposing moving blocks B1, B2, and B3 is connected to the respective parts 16, 20, and 26. On the moving plates (P1, P2, P3) installed in the guide member (L4), such as a normal "LM guide" is installed so as to be able to move in close or opposite directions with each other between the modules (G).

The position converting means 56 is the head (H1, H2, H3) facing each other when the foreign matter removal and bonding operations in both sides contact state on both sides of the module (G) in the work table (2) ) May change the position at the same feed pitch by the screw parts (C1, C2) in different directions during the forward and reverse rotation of the screw (C).

In particular, the power transmission method using the screw (C) formed with the left screw portion (C1) and the right screw portion (C2), respectively, as described above, it is essential that the position deviation occurs when the position changes of the heads (H1 H2, H3) In addition, the feed pitch of the heads H1, H2, and H3 facing each other may be easily adjusted by appropriately adjusting the rotational motion of the screw C according to the thickness and shape of the module G. I can regulate it.

The polarizing film bonding apparatus according to the present invention may further include a buffer means 58 for buffering the contact force transmitted to the module G side when performing a series of operations such as removing foreign matter and bonding.

As the shock absorbing means 58, an elastic member 60, such as a tension coil spring, which elastically connects each of the heads H1, H2, H3 facing each other, as shown in FIGS.

Each of the heads H1, H2, and H3 is adjacent to each other by the guide member L5 such as a conventional " LM guide " on the respective moving blocks B1, B2, and B3, as shown in the drawing. It is installed to be movable in the direction.

The facing heads H1, H2, and H3 are elastically spaced by the elastic member 60 on the respective moving blocks B1, B2, and B3, so that the modules G are interposed therebetween. When the heads H1, H2, and H3 are in close contact with each other and both sides contact each other, the position may be changed elastically to cushion the contact shock transmitted to the surface of the module G. Such a buffer structure can prevent the surface of the module G from being damaged or broken due to excessive contact pressure during double-sided operation.

As described above, the present invention can be easily bonded to the polarizing film on both sides of the substrate module as a series of work processes such as foreign matter removal and bonding proceeds in a two-sided work method.

In particular, since the operation proceeds in both contact state under the same working conditions in the above-mentioned process in each process, as well as the bonding quality of the polarizing film and can greatly improve the work efficiency and productivity.
