Referring to the operation of the hole forming apparatus 100 of the display member for a display device according to an exemplary embodiment of the present invention as described above are as follows. In addition, the following description of the operation of the present invention preferably constitutes one embodiment of the hole forming method of the display member for a display device according to a preferred exemplary embodiment of the present invention.

First, the plurality of display members P moves the loader unit 150 loaded on the loading unit of the loader frame 154 near the loading unit 111 of the table unit 110 to thereby position the loader unit 150. The unloader unit 170 of the table unit 110 may include an unloader unit 170 capable of accommodating the display member P supplied to the unloader 115 after being processed by the machining unit 130. 115) to prepare for the hole forming process by fixing the position of the unloader unit 170 by moving to the vicinity.

Subsequently, when a start signal is given by the controller, the first mobile unit 160 operates. Accordingly, the first moving block 164 of the first moving unit 160 moves along the first LM guide 162 to the upper portion of the loader unit 150. In addition, the first moving cylinder 166 lowers the first pickup / placer 168, and then the nozzle parts 161 of the first pickup / placer 168 come into contact with the display member P. When the pump is operated in this state, a vacuum is formed in the nozzles 161 to pick up the display member P. The first moving cylinder 166 then raises and lowers the first pickup / placer 168, and the first moving block 164 moves along the first LM guide 162 to the rotary table 112 of the table unit 110. Move to the loading unit 111 of. Thereafter, when the vacuum of the nozzle units 161 is released while the first pickup / placer 168 is lowered by the first moving cylinder 166, the display member P is connected to the loading unit 111. It is mounted with an empty tray 114 positioned. Here, it will be understood by those skilled in the art that the empty tray 114 has a predetermined position of the jig 114a to correspond to the size of the display member P to be processed. Meanwhile, in this process, the sensor 158 of the loader unit 150 senses the position of the display member P of the loader unit 150 and sends a signal to the controller, and the controller raises the loader driving source 156. The uppermost display member P is prepared to be loaded in the next step.

Next, when the display member P is positioned on the empty tray 114 of the loading unit 111, the rotary table 112 is rotated 90 degrees. Then, the tray 114 in which the display member P to be processed is located is rotated to the processing unit 113, and the empty tray 114 existing in the cleaning unit 117 is moved to the loading unit 111. The loading of the new display member P is prepared. The loading process of the new display member P is as described above.

Subsequently, when the tray 114 on which the display member P is positioned is moved to the processing unit 113 to fix the position of the rotary table 112, the cameras 124 of the inspection unit 120 may display the display member P. Take a picture of the position of the pair of corners and transmit it to the controller. The control unit calculates the absolute coordinates of the display member P located in the tray 114 located in the processing unit 113 and moves the XY stage 132 of the processing unit 130 according to the information. 134) correct the position.

Next, when the position of the laser nozzle 134 is correctly set by the above correction, the controller operates the laser source 136 and turns on the laser nozzle 134 to irradiate the laser light to a predetermined position of the display member P. do. Then, the predetermined area of the display member P is punctured by the laser light emitted from the laser nozzle 134. In this process, by-products such as debris for forming holes are sucked through the suction holes 137 of the suction member 138 installed around the laser nozzle 134, thereby debris from the hole processing of the display member P. Can be processed.

Subsequently, when the hole drilling operation is completed by the machining unit 130, the turntable 112 rotates 90 degrees again. Then, the tray 114 housing the display member P, which has been processed by the processing unit 113, moves to the unloading unit 115.

Next, the processed display member P positioned on the tray 114 in the unloading unit 115 is mounted to the mounting portion of the unloader unit 170 by the second moving unit 180. To this end, the second moving block 184 of the second moving unit 180 moves to the unloading unit 115 along the second LM guide 182. Thereafter, the second moving cylinder 186 lowers the second pickup / placer 188, and the nozzle portions 181 operated by the pump suck the display member P. As shown in FIG. Then, the second pick-up / placer 188 is raised by the second moving cylinder 186, and the second moving block 184 is located above the mounting portion of the unloader unit 170 along the second LM guide 182. Go to. Thereafter, when the second moving cylinder 186 releases the second pickup / placer 188 from the vacuum of the nozzle parts 181 near the surface of the unloader plate 172, the display member P is unloaded. It is stored in the unloader frame 174 of the loader unit 170.
