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 100 is provided at one side of the body 110 and the body 110, and a panel seating part 120 seating the TFT panel 90 to which the protective film 40 is to be peeled off. And a panel standby part 125 provided on the other side of the body 110 and the TFT panel 90 from which the protective film 40 has been peeled off, and a panel seating part 120 and a panel waiting part waiting for a subsequent process. It is provided between the protective film peeling module 160 and the panel mounting portion 120 and the protective film peeling module 160 provided between the 125 to peel the protective film 40 attached to the TFT panel 90. Adsorbs and transfers the TFT panel 90 seated on the panel seating portion 120 or the TFT panel 90 loaded from the outside so that the protective film 40 of the TFT panel 90 is peeled off and transported according to the process. It consists of a unit 130 and a central control module (not shown in the figure). When the lower protective film removal unit 100 is supplied to the panel mounting unit 120 by receiving the TFT panel which has passed through the alignment unit and the cleaning unit through a separate panel transfer machine (not shown), The panel transfer unit 130 absorbs the TFT panel 90 seated on the panel seating unit 120 and transfers the TFT panel 90 to the protective film peeling module 160 so that the TFT-LCD TFT panel 90 Peel off the protective film 40 attached to the), when the TFT panel 90 adsorbed to the panel adsorption unit 132 is completed transfer to the upper side of the protective film peeling unit 190, the panel transfer robot 131 The provided suction unit moving unit 140 rotates the TFT panel 90 absorbed by the panel suction unit 132 together with the panel suction unit 132 by a predetermined angle using a direct driving motor. The TFT panel 90 adsorbed by the panel adsorption unit 132 has one corner portion 95 facing the front of the TFT panel 90. The diagonal direction of the TFT panel 90 is parallel to the movement path of the panel transfer robot 131. At this time, the adsorption unit moving unit 140, when the TFT panel 90 and the panel adsorption unit 132 rotates, the diagonal direction of the TFT panel 90 is already the main plate 134 and the up / down plate 138. It is preferable to rotate so as to be parallel to the plate plate 136 disposed in a diagonal direction. Therefore, the push plate 136 is parallel to the movement path of the panel transfer robot 131, and when the rotation of the TFT panel 90 is completed, the suction unit moving unit provided in the panel transfer robot 131 ( 140 is a panel adsorption so that the front end of the TFT panel 90 adsorbed to the panel adsorption unit 132 using an air cylinder or the like to contact the upper surface of the peeling roller 191 of the protective film peeling unit 190 at a predetermined pressure. The unit 132 is lowered a predetermined distance in the downward direction. Accordingly, the front end portion of the TFT panel 90 adsorbed to the panel adsorption portion 132 contacts the upper surface of the peeling roller 191, and the protective film 40 that is already attached to the front end portion of the TFT panel 90. Is bonded to the adhesive tape 50 supplied in advance to the upper surface of the peeling roller 191. Subsequently, when the protective film 40 attached to the front end of the TFT panel 90 is completely adhered to the adhesive tape 50 supplied to the peeling roller 191, the peeling roller moving cylinder 192 is like this. The peeling roller 191 in the state is moved forward by a distance of about 50 mm and then returned to its original state. Accordingly, the protective film 40 adhered to the adhesive tape 50 of the peeling roller 191 is in a peeled state by about 50 mm according to the reciprocating movement of the peeling roller 191. Thus, when the protective film 40 is peeled about 50mm, the panel transfer robot 131 is adsorbed to the panel adsorption unit 132 and the panel adsorption unit 132 by using the adsorption unit moving unit 140. The TFT panel 90 is raised by about 10 mm. Subsequently, when the panel adsorption part 132 and the TFT panel 90 adsorbed by the panel adsorption part 132 are completed by about 10 mm, the panel transfer robot 131 maintains a constant speed such TFT. The panel 90 is moved a predetermined distance in front of the TFT panel 90. At the same time, the protective film collection unit 174 rotates the air chuck 175 at a predetermined speed and the adhesive tape 50 supplied to the peeling roller 191 and the protective film 40 peeled off by the adhesive tape 50. Will be wound sequentially. Then, the ion generator of the antistatic portion 180 will continue to generate a predetermined ion toward the peeling portion. In addition, the tape unwinding unit 167 of the adhesive tape supply unit 172 releases a predetermined amount of the adhesive tape 50 from the adhesive tape supply unit 172 in advance and then attaches the adhesive tape 50 of the protective film collection unit 174. ) The adhesive tape 50 is continuously supplied to the peeling roller 191 in accordance with the winding and forward movement of the panel transfer robot 131.

Accordingly, the protective film 40 attached to the TFT panel 90 is attached to the protective film 40 by winding the adhesive tape 50 of the protective film collection unit 174 and by moving the panel transfer robot 131 in all directions. It is peeled off from the TFT panel 90, and after peeling off, it is all wound on the air chuck 175 of the protective film collection unit 174. In addition, since the ion generator continuously generates predetermined ions toward the peeling part when the protective film 40 is peeled off, static electricity due to the peeling of the protective film 40 is not generated at all.

On the other hand, when the protective film 40 of the TFT panel 90 adsorbed to the panel adsorption unit 132 of the panel transfer unit 130 is peeled off, the panel transfer robot 131 is the TFT adsorbed to the panel adsorption unit 132. The panel 90 is transferred to the coalescing unit 125 to proceed with the subsequent process. At this time, the adsorption unit moving unit 140 provided in the panel transfer robot 131 rotates to return the TFT panel 90 adsorbed to the panel adsorption unit 132 together with the panel adsorption unit 132. As described above, when the backlight unit is loaded on the coalescing unit 125 in a state of being seated on the jig, the TFT panel 90 which is adsorbed is seated on the upper portion of the backlight unit.
