[0023] The clamping member includes an extension frame 36 fixedly arranged on the movable platform 32 and away from one end of the positioning frame 37, a clamping rod 34 is inserted into the extension frame 36, and a clamping hole 38 is formed inside the sleeve rod 35 to accommodate the sliding insertion of the clamping rod 34; Reference Manual Attached Figure 7 It can be seen that the purpose of the movable interlacing of the clamping hole 38 and the clamping rod 34 is to facilitate the upper and lower removal of the sleeve rod 35. When in use, the spacer rubber ring is put onto the outer surface of the sleeve rod 35, and then put into the middle of the lower barrel 33. Through the positioning of the clamping rod 34, the sleeve rod 35 can be flexibly installed inside the lower barrel 33.

[0024] The lifting member includes guide grooves respectively provided on both sides of the inside of the bottom cylinder 40, arc sleeves 43 are provided at both ends of the outside of the bottom cylinder 40 and inside the guide grooves, connecting blocks 41 are slidably installed inside the two groups of guide grooves, arc rods 39 are provided at the lower ends of the two groups of connecting blocks 41, and U-shaped rods 44 are commonly provided at the upper ends of the two groups of connecting blocks 41, and a mounting head 45 is sleeved in the middle of the outside of the U-shaped rod 44, and a cylinder 42 is provided at the upper end of the mounting head 45, and the cylinder 42 is fixedly arranged inside the sleeve rod 35, and the two arc rods 39 are in sliding contact with the inner wall of the bottom cylinder 40; Reference Manual Attached Figure 7 , Figure 8 and Fig. 9 It can be seen that the arc sleeve 43 can clamp the bottom tube 40 with two sets of guide grooves; The cylinder 42 is arranged to drive the U-shaped rod 44 to move inside the sleeve rod 35, so that the connecting block 41 and the arc rod 39 move upward, causing the spacer rubber ring that originally abutted against the outside of the arc rod 39 to move toward the inside of the lower barrel 33. As the arc rod 39 gradually moves upward, the arc rod 39 contacts the lower end edge of the lower barrel 33. During the extrusion contact process, the spacer rubber ring below the outside of the arc rod 39 can fall off from the arc rod 39, and the spacer rubber ring is positioned on the surface of the corresponding glass body 7. The arc rod 39 can be made of spring rod, rubber rod or other resilient materials.

[0025] The slide 13 at the screw 11 inside the corresponding frame 10 is threadedly matched with the screw 11, and the slide 13 inside another group of frames 10 is slidably matched with the guide rod 22. One end of the screw 11 passes through the outer side of the corresponding frame 10 and is connected to the second motor 15. The second motor 15 is fixedly installed on the outer wall of the frame 10 at the corresponding position. Blocks 14 are fixedly arranged on both sides of one end of the belt conveyor 9 and at the corresponding position of the L-shaped frame 3. The block 14 slides on the outer side of the L-shaped frame 3. Reference Manual Attached Figure 1 , Figure 2 , Figure 3 , Figure 4It can be seen that after the second motor 15 is connected to an external power supply, it can drive the screw 11 to rotate. The slide 13 corresponding to the thread of the screw 11 can drive the two groups of slides 13 to move together inside the corresponding frame 10 under the sliding limit of the guide rod 22, thereby completing the position adjustment of the stacking.

[0026] Working principle: The roller conveyor 2 can transport the glass body 7 to the lifting mechanism in an orderly manner at intervals, and then, driven by the second motor 15, the two slides 13 drive the support arms 28 to approach the glass body 7, and then, under the telescopic drive of the hydraulic cylinder 26, the use height of the support arms 28 is adjusted to meet the use of each group of negative pressure pumps 29 at the I-shaped frame 30. The negative pressure pump 29 can transport the glass body 7 to the upper surface of the storage rack 20 by means of the suction head 31, and then, under the drive of the lifting mechanism, the height of the belt conveyor 9 is lowered to meet the later stacking of the glass body 7. When the suction head 31 absorbs the next glass body 7, the support arm 28 moves to the top of the roller conveyor 2, and the L-shaped rod 23 at the rear end drives the support rod 27 to move with the movement of the slide 13, corresponding to the top of the placed glass body 7, and then through the telescopic drive of the cylinder 42 inside the sleeve rod 35. The U-shaped rod 44 and the connecting block 41 at the lower end of the lower mounting head 45 are moved, causing the U-shaped rod 44 and the connecting block 41 at the lower end of the lower mounting head 45 to lift the arc rod 39, so that the spacer rubber ring pre-filled in the lower barrel 33 can slide from the outside of the sleeve rod 35. In the absence of the arc rod 39, the spacer rubber ring contacts the edge of the lower barrel 33 as the arc rod 39 moves upward, and then slides to the surface of the glass body 7 by itself during the extrusion process. Therefore, when the support arm 28 adsorbs the glass body 7, the lower barrels 33 at both ends of the support rod 27 also immediately complete the placement of the spacer rubber ring, and the placement position is accurate, which can greatly improve the stability of the stacked glass body 7. After the stacking is completed on one side of the rack 20, the glass body 7 on the upper surface of the rack 20 can be transported to the external transportation mechanism by the belt conveyor 9, and the external transportation mechanism transports the rack 20 and the glass body 7 as a whole.
