The specific embodiment

Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, load/unload mechanism of the present utility model comprises symmetrical frame 20 of shape and the rectangular-shaped bench board casing 33 that is installed in frame 20 middle positions, and the upper surface of bench board casing 33 is a bench board 8.The roller transmissioning device that is used for gripping transmission flat panel workpieces that the lifting connecting mechanism of the flat panel workpieces 7 that is used on the self-powered platform 8 is installed in bench board casing 33 and is arranged symmetrically in and arranged on left and right sides above the bench board casing 33.

As Fig. 1, Fig. 3, shown in Figure 7, the lifting connecting mechanism in the utility model comprises fixing or is placed on base 19 on bench board casing 33 base plates, is fixed on two bearing back plates 34 on the base 19, is installed in two transmission shaft 14 and transmission shaft driver trains on the bearing back plate 34 by bearing 35.Described transmission shaft driver train comprises the CD-ROM drive motor 21 that is fixedly mounted on the bearing back plate 34, be installed in the driving gear 12 on CD-ROM drive motor 21 output shafts and be installed on the transmission shaft 14 and with driving gear 12 ingear driven gears 14.Certainly, also can adopt the driver train of other types.On transmission shaft 14, be installed with two cams that phase place is identical, outer contour shape is identical 16.

Be fixed with two guide pillars 18 on the base 19, be movably installed with on each guide pillar 18 on 17, two guide pin bushings 17 of a guide pin bushing and be symmetrically fixed with two connecting plates 11, be fixed with two pairs of ejector pin 10 symmetric arrangement on 10, two connecting plates 11 of a pair of ejector pin on every connecting plate 11.Ejector pin 10 stretches out the hole on the bench board 8, can with flat panel workpieces 7 contact matching.Track roller 9 with cam 16 cooperatings is installed on the connecting plate 11.Also track roller 9 can be set, at this moment, every connecting plate 11 and corresponding cam 16 direct contact cooperatings.

As Fig. 1, Fig. 3, Fig. 5, shown in Figure 6, roller transmissioning device in the utility model comprises the cylinder 1 that is fixed on the frame 20, be fixed on the frame 20 two guide rails 22, the guide rail slide block 4 that cooperates with guide rail 22, the transfer plate 3 of rectangle that is fixed on guide rail slide block 4, wherein transfer plate 3 is captiveed joint with the cylinder rod of cylinder 1 by contiguous block 2, near bench board casing 33 1 sides several roller shafts 5 are installed evenly on the transfer plate 3, a roller 6 is installed on each roller shaft 5.

The utility model is when work, and two cylinders 1 in the roller transmissioning device start, and drive two transfer plates 3 and relatively move along guide rail 22, arrange rollers 6 until two of two transfer plates 3 and clamp flat panel workpieces 7 simultaneously, and cylinder 1 stops.
