Figure 7 is a TFT-LCD module assembly assembly according to the present invention, the overall configuration for explaining the protective film removing unit.
Referring to FIG. 7, the protective film removing unit 500 performs a function of peeling the protective film attached to the TFT panel before the TFT panel and the backlight unit are merged in the coalescing part, preferably by the present applicant. The "protective film peeling apparatus of TF-LCD panel" previously applied by 36147 can be applied.

Referring to FIG. 7, the protective film removing unit 500 is provided at one side of the body 510 and the body 510, and a panel seating part for seating the TFT panel 60 to which the protective film (not shown) is to be peeled off. 520 and the panel waiting portion 525, which is provided on the other side of the body 510, in which the protective film is peeled off, and waits for a subsequent process, and the panel seating portion 520 and the panel waiting portion 525. ) Is provided between the protective film peeling module 560 and the panel seating portion 520 and the protective film peeling module 560 to peel off the protective film attached to the TFT panel 60 and the TFT panel (60). The panel transfer unit 530 and the central control module which adsorb the TFT panel 60 seated on the panel seating part 520 or the TFT panel 60 loaded from the outside to transfer the protective film according to the process. (Not shown in the figure). The protective film removing unit 500 receives the TFT panel 60 which has passed through the alignment unit 300 and the cleaning unit 400 through a separate panel transfer machine (not shown). When loaded on the seating part 520, the panel transfer unit 530 absorbs the TFT panel 60 seated on the panel seating part 520 to transfer the TFT panel 60 to the protective film peeling module 560. The protective film attached to the TFT-LCD TFT panel 60 is peeled off. When the TFT panel 60 adsorbed to the panel adsorption part 532 is transferred to the upper side of the protective film peeling part 590, the panel is transferred. The suction unit moving unit (not shown) provided in the robot 531 uses a direct driving motor or the like to advance the TFT panel 60 adsorbed to the panel suction unit 532 together with the panel suction unit 532 at a predetermined angle. Rotate by as much as possible, and thus the TFT panel 60 adsorbed to the panel adsorption part 532 has one corner portion 65 at the front of the TFT panel 60. The diagonal direction of the TFT panel 60 is parallel to the movement path of the panel transfer robot 531. At this time, the adsorption unit moving unit has a diagonal direction of the TFT panel 60 when the TFT panel 60 and the panel adsorption unit 632 are rotated to the main plate (not shown) and the up / down plate (not shown). It is preferable to rotate so as to be able to be in parallel with a burr plate (not shown) arranged in a diagonal direction. Therefore, the push plate is parallel to the movement path of the panel transfer robot 531. When the rotation of the TFT panel 60 is completed, the suction unit moving unit provided in the panel transfer robot 531 is an air cylinder or the like. The panel adsorption portion 532 is lowered such that the front end portion of the TFT panel 60 adsorbed to the panel adsorption portion 532 is contacted with a predetermined pressure on the upper surface of the peeling roller 591 of the protective film peeling portion 590 by using a. The predetermined distance is lowered in the direction. Accordingly, the front end of the TFT panel 60 adsorbed by the panel adsorption part 532 is in contact with the top surface of the peeling roller 591. The protective film, which is already attached to the front end of the TFT panel 60, is peeled off. It is bonded to the adhesive tape 50 supplied in advance on the upper surface of the 591. Subsequently, when the protective film attached to the front end of the TFT panel 60 is completely adhered to the adhesive tape 50 supplied to the peeling roller 591, the peeling roller moving cylinder 592 is peeled in such a state. The roller 591 is moved forward by a distance of about 50 mm and then returned to its original state. Accordingly, the protective film adhered to the adhesive tape 50 of the peeling roller 591 is in a peeled state by about 50 mm according to the reciprocating movement of the peeling roller 591. In this way, when the protective film is peeled off by about 50 mm, the panel transfer robot 531 uses the adsorption unit moving unit to remove the panel adsorption unit 532 and the TFT panel 60 adsorbed to the panel adsorption unit 532. It will raise about 10mm. Subsequently, when the panel adsorption part 532 and the TFT panel 60 adsorbed by the panel adsorption part 532 are completed by about 10 mm, the panel transfer robot 531 maintains a constant speed such TFT. The panel 60 is moved a predetermined distance in front of the TFT panel 60. At the same time, the protective film collection unit 574 rotates the air chuck 575 at a predetermined speed to sequentially release the adhesive tape 50 supplied to the peeling roller 591 and the protective film peeled off by the adhesive tape 50. It is wound. Then, the ion generator of the antistatic portion 580 continues to generate a predetermined ion toward the peeling portion. In addition, the tape unwinding unit (not shown) of the adhesive tape supply unit 572 releases a predetermined amount of the adhesive tape 50 from the adhesive tape supply unit 572 in advance and then attaches the adhesive tape of the protective film collection unit 574. 50) The adhesive tape 50 is continuously supplied to the peeling roller 591 in accordance with the winding and moving of the panel transfer robot 531.

Therefore, the protective film attached to the TFT panel 60 was all attached to the TFT panel attached to the protective tape collection unit 574 by the adhesive tape 50 winding and the panel transfer robot 531 moved forward. It is to be peeled off at 60, and after being peeled off are all wound on the air chuck 575 of the protective film collection unit 574. In addition, since the ion generator 476 (see FIG. 7) continues to generate predetermined ions toward the peeling part when the protective film is peeled off, static electricity due to the peeling of the protective film is not generated at all.

Meanwhile, when the protective film of the TFT panel 60 adsorbed to the panel adsorption part 532 of the panel transfer unit 530 is peeled off, the panel transfer robot 531 is the TFT panel 60 adsorbed to the panel adsorption part 532. ) Is transferred to the coalescing unit (see FIG. 1) to proceed with the subsequent process. At this time, the adsorption unit moving unit provided in the panel transfer robot 531 rotates to return the TFT panel 60 adsorbed to the panel adsorption part 532 together with the panel adsorption part 532 and coalesce as described above. When the backlight unit 80 is loaded in the seated state, the TFT panel 60, which is adsorbed, is seated on the backlight unit 80.
