In addition, use a microscope or the like to perform visual inspection. 20 The figure 1 shows a horizontal type automatic detection device as a representative example. As shown in the figure, the automatic detection device includes a main body 12 whose entire surface is "inclined at a predetermined angle, for example, 60 °", and a liquid crystal panel supply section 20 for supplying an object to be inspected (hereinafter referred to as "liquid crystal panel P"). The inspection unit 30 loads the liquid crystal panel p supplied from the liquid crystal panel supply unit 20, and illuminates the light source 1231964 (not shown) provided on the bottom surface to check for unevenness or liquid crystal panel P generated during the manufacturing process. The broken lines of the lean material line and the door line are equal in color; and the panel bracket 60 is composed of at least two transporting devices that transport the liquid crystal panel P to the liquid supply unit 20 and the inspection unit 30. The liquid crystal panel supply unit 20 is provided with an auxiliary stage 50 for supplying the liquid crystal panel. The auxiliary stage 50 is selectively placed in a waiting state in cooperation with a two-layer, 5-state panel bracket 60. While the liquid crystal panel p waiting for inspection is being moved toward the inspection table 32 of the inspection section 30 by any of the conveying devices and the inspection is performed, a new uninspected liquid crystal panel p is loaded on the auxiliary table 50. In addition, at the end of the inspection of the liquid crystal panel P, any one of the transporting devices unloads the inspected liquid crystal 10 panel P from the inspection table 32 and then moves it to the auxiliary table 50 of the supply section 20 again, and the other transporting device The new uninspected liquid crystal panel P loaded on the auxiliary table 50 is conveyed toward the inspection table 32 of the inspection section 30. By repeating this procedure, the inspection of the liquid crystal panel P can be performed continuously. Such a panel bracket 60 includes, as shown in FIGS. 2 and 3, a pair of guide rails 62 and 64 provided opposite to the entire length of the supply section 20 and the inspection section 30 of the liquid crystal panel 15 and opposed to the guides 62 and 64. The opposite pair of guides 62 ', 64', which are arranged parallel to each other at the lower part, are separated along the pair of guides 62, 64 or a pair of guide rails 62 ', 64' to move horizontally into the upper and lower layers. The first and second transfer arms 70 and 80 are connected to the ends of each of the transfer arms 70 and 80 and move the first and second transfer arms 70 and 80 horizontally by moving along 20 guides, respectively. The transfer bodies 61, 63, 65, 67 are connected to one of the upper and lower layers of the first and second transfer arms 70, 80, such as the lower transfer bodies 65, 67, and can drive the transfer body 65 , 67 is a plurality of driving mechanisms 90 moving. As shown in FIG. 2, the first transfer arm 70 includes a frame member 72 to which 1231964 is mounted. There are two pairs of guides 71 and 71 ′ provided vertically from the upper and lower left and right end portions toward the inside of the transfer arm 70. A pair of upper and lower moving blocks 76 that can be mounted freely up and down along the guide 71 '71'; and a plurality of clamps 75 provided on the inner end side of each of the moving blocks 76 and holding the liquid crystal panel p. The structure 5 of the moving block 76 is such that it advances in a vertical symmetrical direction by a cylinder (not shown), and holds the liquid crystal panel p in an inserting manner using a jig 75.

However, the moving blocks 76 and 78 of the conventional panel bracket 60 having this structure consider the size corresponding to the type of the liquid crystal panel P to be subjected to the lighting inspection, and the moving blocks 76 and 78 are moved by only 10 guides 71 manually. , 71, 73, 73, and the scales indicated above are set in advance before the equipment is running. Therefore, when the size of the liquid crystal panel P is changed, there is a problem that the settings of the equipment must be changed again by manual operation according to the data of the model. In addition, because the structure holds the liquid crystal panel P by a clamp Even if the same liquid crystal panel p is loaded, the liquid crystal panel p is slightly misaligned. When moving to another step in this state, for example, when moving toward the inspection section 30 for inspection of lighting, the inspection position of the liquid crystal panel p changes, and thus different inspection results are obtained, which reduces inspection reliability. For a small 20-inch liquid crystal panel, even if there is no particular problem in the reliability of the inspection, in the case of a recently enlarged liquid crystal panel, even if the angle is slightly shifted at the center of the panel, the inspection position at the peripheral end Changes will increase and have a serious impact on reliability during lighting inspections. In addition, since the missing piece 1231964 75 included in the above-mentioned liquid crystal panel automatic gripping device is pinched in the inside of the moving blocks 76 and 78, when holding and transferring a large liquid crystal panel of 30 inches or more, There may be a side end of the liquid crystal panel or a face crystal panel.

As another embodiment, the liquid crystal panel P is sandwiched by the light receiving sensor and the light emitting sensor up and down, and it is obvious that the degree of misalignment of the liquid crystal panel P can be detected. When the peripheral portion of the liquid crystal panel P and the liquid crystal panel P are misaligned, a touch sensor that contacts the liquid crystal panel and generates an electric signal may be used. 15 20

A new type of liquid crystal panel is mounted on the liquid crystal panel supply section 22. The control section in the inspection device inputs the changed liquid crystal panel / related ㈣. The athlete can change the movement of the automatic device according to whether the type of the LCD panel ρ is already present in the control unit. The detection mechanism 15 on the fixing jig 158 is called the detector _ Wei Ka Jing Jing (not shown) 13 1231964 each drive source 154 is operated to drive the transfer table transfer screw 152 separately, and then the transfer table transfer screw 152 is rotated separately The transfer stage bracket block 156 and the transfer stage 162 move toward the surface of the liquid crystal panel P. The liquid crystal panel P is approached by the transfer table 162, and at the same time, if the surface of the liquid crystal panel P is detected by the inspection mechanism 157 mounted on a pair of fixing fixtures 158, there is no misalignment. Since the liquid crystal panel P is loaded, the control section stops its driving The operation of the source 154 is to stop the rotation of the transfer table transfer screw 152. At this time, the moving distance data of the transfer table 162 is transmitted to the control unit and stored, so that it can be used when the liquid crystal panel P of the same model is loaded into the transport device. Next, the moving jigs 159 mounted on both sides of the fixed jig 158 are moved left and right, respectively, and the detection mechanism 157 mounted on the moving jig 159 detects the surface of the liquid crystal panel p. The detection mechanism 157 mounted on the moving jig 159 until the moment when the liquid crystal panel p cannot be detected, obtains the width dimension data of the liquid crystal panel p based on the moving distance of the moving jig 159 and transmits it to the control section. The control unit calculates the position of the mobile jig 159 that can be safely held by the loaded liquid crystal panel p 15 and transmits a control signal to a drive source 191 provided integrally with the mobile jig 159 to move the mobile jig 159 toward a predetermined position. The actuators 192 and 192 'having the clamps 158 and 159 at the ends of the transfer table 162 are moved at the same time, and the fixed clamp 158 and the movable clamp 159 are moved toward the side. By holding the liquid crystal panel p, the holding of the liquid crystal panel p is completed. . 20 In contrast, when the detection mechanism 157 mounted on one of the fixing fixtures 158 detects the liquid crystal panel and the detection mechanism 157 of the other fixing fixture 158 does not detect the liquid crystal panel, it means that the amount of displacement is equivalent to that until no detection is performed. The inspector of the LCD panel Hao 7 shut off until the difficult to inspect the crystal panel. μ, since the liquid crystal panel is detected at any side, the control section stops the operation of the drive source 154, 14 1231964 so as to stop the rotation of the transfer table transfer screw 152 detected. After that, the moving distance variable mechanism 16 of the transfer table is used to adjust the moving distance of both ends of the transfer table 162. In other words, "transverse roller bearings 176 are mounted on both sides of the transfer table 162". Since either of the transfer tables ι62 is equipped with a horizontal 5 roller bearing 173 for linear movement, the drive source 154 is operated so that only the When any one of the transfer table transfer screws 152 is rotated, the transfer table bracket block 156 of the stopped transfer table transfer screw 152 is used as an axis, and the undetectable transfer table bracket block 156 is lowered to correct misalignment. Next, after the moving jig 159 mounted on the transfer table 162 operates in the same manner as described above, the liquid crystal panel P is held by the fixed jig 10 158 to complete the holding of the liquid crystal panel P. In the case where the data input by the operator already exists in the control section, the driving source 154 is driven corresponding to the data, the transfer table transfer screw 152 is rotated, and the transfer table 162 is moved while the moving distance between the two ends is adjusted. The interval between the ends of 158 and 159 and the end of the mounted liquid crystal panel p is set to, for example, I5 to be 2 to 5 mm. After the transfer stage 162 is provided, the driver provided with the clamps 158 and 159 at the ends of the transfer stage 162 is moved. The clamps 158 and 159 advance to the uranium uranium and hold the liquid crystal panel P to complete the holding of the liquid crystal panel p. At this time, when the liquid crystal panel p is not held securely according to the data operation result existing in the control unit in this way, for example, when the liquid crystal panel P is misplaced and a part of the fixture 20 cannot hold the liquid crystal panel P, all the clamps 158 are used. After the control is released, the transfer table 162 is returned to the original position, and the control of the liquid crystal panel P is attempted again in the same manner as in the case where the inputted data does not exist in the control section. For example, as shown in FIG. 10A, when the small liquid crystal panel p is supplied to the center of the frame 132 of the supply unit 220 in a proper position, the liquid crystal panel is not detected by any of the detection mechanisms 157 15 1231964. When the source 154 is operated so that each of the transfer table transfer screws 152 rotates at the same time, the upper and lower transfer tables 162 and the frame 132 move from the dotted line position to the solid line position in parallel, and then the liquid crystal panel P is held by the clamps 158 and 159. 5 In contrast, as shown in FIG. 10B, when the large liquid crystal panel P is supplied to the lower portion of the frame 132 of the supply unit 220 without being displaced, the upper detection mechanism 157 cannot detect the liquid crystal panel. When the operation is performed so that each of the transfer table transfer screws 152 rotates simultaneously, the upper transfer table 162 moves from the dotted line position to the solid line position in parallel with the frame 132, and then the liquid crystal panel P is held by the clamps 10 158 and 159. In addition, as shown in FIG. 10C, when the small-sized liquid crystal panel P is fed to the center of the frame 132 of the supply unit 220 in an offset manner, the liquid crystal panel is not detected by any of the detection mechanisms 157 of the upper, lower, left, and right. Each drive source 154 operates so that each transfer table transfer screw 152 rotates simultaneously until each detection mechanism 157 detects a liquid crystal panel. Then, when any one of the detection mechanisms 157 detects the liquid crystal panel, the rotation of the transfer screw 152 that performs the detection is stopped. As a result, the transfer table bracket block 156 moving along the transfer screw 152 also stops. Thereafter, until the surface of the liquid crystal panel p is detected by the other detecting mechanism 157, the moving distance variable mechanism 160 of the 20 transfer table lowers the other transfer table bracket block 156 and corrects the misalignment, so that the transfer table 162 is only shifted by the angle 0. In this way, both the upper and lower transfer tables 162 can rotate the liquid crystal panel p by an angle shifted, and the liquid crystal panel p can be automatically held by the clamps 158 and 159 when the liquid crystal panel p is held by the clamps 158 and 159. 16 1231964 The process of loading the liquid crystal panel p loaded by the auxiliary stage onto the panel tray from the liquid plate supply unit 220 to the inspection unit 23 is performed as follows. Embodiment 1 After the liquid crystal panel p held on the panel pallet is shifted to the inspection table of the inspection unit 230 in an out-of-position state, the data of the liquid crystal panel P held on the panel is transmitted to k. The control unit transmits a control signal to the inspection table, and the inspection port 232 corresponds to the misalignment of the liquid crystal panel mounted on the panel bracket, and receives the liquid plate below the center of the shape. End LCD panel at inspection table 232? After the inspection, the liquid crystal panel with a misaligned position was held on the panel bracket as it was, and then, it was transported to the liquid crystal panel supply section 22 (). After that, the data of the liquid crystal panel loaded from the panel bracket is transmitted to the control unit, and the control unit transmits the control signal to the auxiliary station 250, and the auxiliary station 25 receives the liquid crystal panel loaded on the panel bracket according to the misalignment of the liquid crystal panel. LCD panel. 15 Embodiment 2 The data of the liquid crystal panel held by the panel bracket is shifted to the control section, and the control section transmits the control signal to the driving sources 154 of the first and second conveying devices 130 and 140 of the panel bracket. Each of the transfer table transfer screws 152 connected to the driving source 154 is rotated to adjust the misalignment of the transfer table 162, and the position of the liquid crystal panel P held by the misalignment can be corrected. The corrected liquid crystal panel P is transported from the liquid crystal panel supply section 220 to the inspection section 23o, and is loaded on the inspection table 232 of the inspection section 23o for inspection. After that, the liquid crystal panel that has been inspected is transported from the inspection section 23 to the liquid crystal panel supply section 220 again in a state where the liquid crystal panel has been corrected, and the liquid crystal panel is received by the auxiliary table 250. 17 1231964 In the above description, the panel bracket for automatic detection equipment of the present invention is exemplified by the vertical type, but it is not limited to this. For example, the use of a panel bracket for horizontal automatic detection equipment does not exceed the scope of the present invention. A range within which a person of ordinary skill in the art can make various changes. 5 [Brief description of the drawings] Fig. 1 is a perspective view showing the structure of a conventional automatic detection device.
