Detailed ways

Please refer to Fig. 1, which is an air-floating worktable for positioning liquid crystal panels provided by a preferred embodiment of the present invention. The air-floating workbench includes a loading frame 10, two unwinding devices 20, and a Film advancing device 30.

As shown in Figures 1 to 3, the carrying frame 10 is a quadrilateral frame composed of a first side 11, a second side 12, a third side 13 and a fourth side 14, the carrying frame 10 It has a top surface 15 . The first to fourth sides 11-14 respectively have a plurality of through holes 40 penetrating through the top surface 15, and each through hole 40 is arranged along the inner peripheral edge close to the bearing frame 10, and each through hole 40 can make the compressed gas upward toward the top surface 15 flow out.

The central positions of the first side 11 and the second side 12 respectively have an elongated groove 16, 17 recessed from the top surface 15, and the top surface 15 of the carrying frame 10 has a groove 16 on both sides of the first side 11 Positioning portion 18, the top surface 15 of the carrying frame 10 has a positioning portion 18 on the side of the second side 12 of the cavity 17, each positioning portion 18 is a roller that can rotate in situ, and the bottom of the carrying frame 10 is additionally embedded in the A tablet 19.

As shown in FIG. 5 , each of the unwinding devices 20 includes a driving member 22 and an elongated connecting member 24, each driving member 22 is a pneumatic cylinder, and two ends of the connecting member 24 are respectively provided with a roller 26 that can rotate in situ. , the output shaft of the driver 22 is connected to the central position of the linkage 24, so that the driver 22 can drive the linkage 24 to move between a retreat position as shown in FIG. 1 and an original position as shown in FIG. 5 . The two ejection devices 20 are respectively arranged on the outsides of the positions of the receiving slots 16 and 17 close to the carrying frame 10, and each driving member 22 is fixed on the flat plate 19, so that the linking member 24 faces the inner periphery of the carrying frame 10, and each linking member 24 extends Into the receiving slots 16 , 17 , the height of each roller 26 is slightly higher than the top surface 15 of the bearing frame 10 .

The film feeding device 30 includes a driving part 32 and a linking part 34. As shown in FIG. The extension part 36 at the two ends of the rod body 35 and the output shaft of the driving part 32 are connected to the center of the rod body 35, and the driving part 32 can drive the linking part 34 to move between a feed position as shown in FIG. 4 and an original position as shown in FIG. 3 , The outer ends of each extension part 36 are respectively provided with a roller 38 which can rotate in situ. The film feeding device 30 is located near the third and fourth sides 13, 14 of the carrying frame 10 adjacent to each other. The rollers 38 are located above the third side 13 and the fourth side 14 respectively.

Through the above-mentioned structure, when intending to utilize the utility model to locate the liquid crystal panel, please refer to that shown in Figure 1, the interlocking parts 24 of the two unwinding devices 20 are driven to the retreat position by the driving part 22, so that the two interlocking parts 24 of each interlocking part 20 The distance from the rollers 26 to the inner periphery of the supporting frame 10 is greater than the distance from the positioning portion 18 to the inner periphery of the supporting frame 10 , and the linking member 34 of the secondary film feeding device 30 is driven to the original position by the driving member 32 . Next, a liquid crystal panel 60 is first placed on the top surface 15 of the carrying frame 10, and the outer edge of the bottom surface of the liquid crystal panel 60 will be pushed up by the compressed air flowing out from each through hole 40 of the carrying frame 10 and suspended above the carrying frame 10, The liquid crystal panel 60 is not in direct contact with the top surface 15 .

As shown in Figures 2 and 4, after the placement of the liquid crystal panel 60 is completed, the driving member 32 of the film feeding device 30 promptly pushes the link 34 to move to the feeding position, and each roller 38 simultaneously pushes the liquid crystal panel 60, and the liquid crystal panel 60 Resisting on the three positioning parts 18, using the characteristics that each roller 38 and the positioning parts 18 can rotate in situ, the liquid crystal panel 60 can be moved to the positioning position more smoothly and fixed, and then the viewing and viewing of the liquid crystal panel 60 can be performed. detection work.

After the detection of the liquid crystal panel 60 is completed, as shown in FIG. Then, as shown in Figure 5, the link 24 of the two unwinding devices 20 is driven to move back to the original position, so that the distance from the rollers 26 of each link 24 to the inner circumference of the bearing frame 10 after the movement is less than the distance between the positioning part 18 and the inner circumference of the bearing frame 10. The distance between the inner periphery of the bearing frame 10 and the rollers 26 of each unwinding device 20 can push the edge of the liquid crystal panel 60 to separate from each positioning portion 18, so that the liquid crystal panel 60 leaves the aforementioned positioning position.

Because the liquid crystal panel 60 is positioned in the process of the carrying frame 10, the film feeding device 30 pushes against the two sides of the liquid crystal panel 60 with the rollers 38 of the two extension parts 36 at the same time, so that the liquid crystal panel 60 moves to the positioning position, and the liquid crystal panel 60 In the process of moving, the liquid crystal panel 60 is only in contact with the rotatable roller 38 and the positioning part 18 with its edge, and other parts of the liquid crystal panel 60 are all suspended above the carrying frame 10, thus making the liquid crystal panel 60 not need to be subjected to a relatively high load. It can be moved with a large thrust, and can be positioned on the bearing frame 10 relatively quickly and accurately.

In the utility model, the flat plate 19 and the bearing frame 10 can be arranged in an inclined manner about 75 degrees from the horizontal plane. When the liquid crystal panel 60 is placed on the inclined bearing frame 10, the liquid crystal panel 60 can be affected by gravity and move along the top The surface 15 naturally moves toward the positioning portion 18, and cooperates with the film feeding device 30 to push the liquid crystal panel 60 from the corner of the supporting frame 10, so that the positioning of the liquid crystal panel 60 is more convenient and fast, and the overall manufacturing cost is saved at the same time.

If it is desired to remove the liquid crystal panel 60 from the supporting frame 10, it is only necessary to move the linkage 24 of the second unwinding device 20 back to the original position so that the liquid crystal panel 60 and the positioning part 18 are separated from each other.

Through this, the air-floating workbench provided by the utility model for positioning the liquid crystal panel uses the supporting frame, a single film feeding device and a film unwinding device to cooperate with each other, so that the structure is relatively simple and the movement of positioning the liquid crystal panel is relatively fast. .
