[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] like Figure 1 to Figure 5 A double-station hand gripping device for loading and unloading silicon crystal rods is shown, wherein the upper end surface of the silicon crystal rod 2 is fixedly connected to a crystal support 3 for facilitating the transportation of the silicon crystal rod 2 .

[0020] The hand grip device comprises a hand grip frame 1, a mounting platform 4 is fixed at the center position of the hand grip frame 1, a slewing bearing 5 is arranged on the upper end face of the mounting platform 4, an inner ring gear 14 is arranged on the inner ring wall of the slewing bearing 13, an adapter plate 13 is fixed on the upper end face of the slewing bearing 5, a servo reduction motor 15 is mounted on the adapter plate 13, a driving gear 16 is mounted on the output shaft of the servo reduction motor 15, the driving gear 16 is meshed with the inner ring gear 14 for transmission, and then drives the slewing bearing 5 to rotate to realize a 180-degree slewing motion of the hand grip frame.

[0021] Grabbing mechanisms for grabbing the silicon crystal rod 2 are symmetrically arranged at the left and right ends of the hand grasping frame 1, and the grasping mechanism includes fingers 6 installed on the upper end surface of the hand grasping frame 1 and can be inserted into the crystal holder 3. The lower part of the hand grasping frame 1 is provided with an L-shaped connecting frame 7 that can move left and right, and a connecting plate 10 is fixed to the upper end of the vertical side of the L-shaped connecting frame 7. A slider 11 is fixed to the upper end surface of the connecting plate 10. A slide rail 12 that slidably cooperates with the slider 11 is installed on the bottom surface of the hand grasping frame 1, and a cylinder 22 is installed on the inner side surface of the hand grasping frame 1. The piston rod of the cylinder 22 is fixedly connected to the connecting plate 10 to push the movement of the L-shaped connecting frame 7.

[0022] A rectangular frame 8 is fixedly connected to the end of the horizontal side of the L-shaped connecting frame 7 , and a water receiving tray 9 for placing the silicon crystal rod 2 is provided on the rectangular frame 8 .

[0023] The outer side surface of the water receiving tray 9 is movably connected to the outer side surface of the rectangular frame 8 by a pair of hinges 17 set at a distance. Two positioning plates 18 set at a distance are fixed to the inner side surface of the rectangular frame 8. A positioning bead 19 is installed on the upper end of the positioning plate 18. The front end of the positioning bead 19 has a steel ball 20. A positioning hole is opened on the inner side surface of the water receiving tray 9 for the steel ball 20 to be positioned and inserted.

[0024] Limit pins 21 are respectively installed on both side surfaces of the end of the hand grasping frame 1.
