[0033] Refer to the attached instructions Figure 1 、 Figure 2 、 Figure 3 It can be seen that under the connection of the fixed platform 16 and the track 18, the lifting mechanism drives the movement of the socket 21, so that the overall structure of the sliding platform 17 can move in the vertical direction.

[0034] The lifting mechanism includes a platform fixed on the outer wall of the first bracket 4 and far from the second bracket 5. A lead screw 8 is rotatably installed inside the platform. The bottom end of the lead screw 8 is provided with a first motor 6. The first motor 6 is installed on the upper surface of the base 1. The lead screw 8 is in threaded cooperation with the socket 21;

[0035] Refer to the attached instructions Figure 3 and Figure 4 It can be seen that when the first motor 6 is connected to the power supply, it can drive the corresponding lead screw 8 to rotate, and then make the socket 21 in threaded cooperation with the outside of the lead screw 8 slide on the surface of the lead screw 8, so as to achieve the purpose of lifting;

[0036] The purpose of using two groups of first motors 6 to drive the corresponding lead screws 8 to rotate can make the belt conveyor 9 more stable when lifting. In order to ensure the same moving frequency, an external differential can be used. This component mechanism is an existing technology and will not be elaborated here.

[0037] The lifting mechanism includes a hydraulic cylinder 26 fixed on the inner surface of the sliding frame 13. The telescopic end of the hydraulic cylinder 26 is connected to the lower surface of the sleeve 25;

[0038] Refer to the attached instructions Figure 5 It can be seen that the hydraulic cylinder 26 can drive the sleeve 25 to move flexibly. Furthermore, after the height is adjusted by the lifting mechanism, the use height of the support arm 28 can be automatically adjusted, making it more convenient for the support arm 28 to perform stacking work.

[0039] The placement mechanism includes a fixed rod 24 commonly installed between two sets of sleeve frames 25. A support rod is arranged between the two sets of sleeve frames 25 and on one side of the fixed rod 24. A support arm 28 is commonly arranged outside the support rod and the fixed rod 24. An I-shaped frame 30 is fixedly arranged at the lower end of the support arm 28. Negative pressure pumps 29 are arranged at the corners of the upper surface of the I-shaped frame 30. Suction heads 31 are connected and installed below the interiors of the four negative pressure pumps 29. L-shaped rods 23 are fixedly arranged at both outer ends of the fixed rod 24.

[0040] The blanking mechanism includes a support rod 27 fixedly arranged below the outer side of the L-shaped rod 23. Positioning frames 37 are fixedly arranged at both ends of the support rod 27. Moving platforms 32 are slidably installed inside the positioning frames 37. A blanking cylinder 33 is arranged inside the moving platform 32. A clamping member is arranged on the outer side of one end of the moving platform 32 away from the positioning frame 37. A sleeve rod 35 is arranged inside the blanking cylinder 33. A bottom cylinder 40 is arranged at the lower end of the sleeve rod 35. A lifting member is arranged inside the bottom cylinder 40;

[0041] Refer to the attached instructions Figure 6 It can be seen that the moving platform 32, the extension frame 36, and the blanking cylinder 33 can all slide flexibly inside the positioning frame 37 according to the downward movement of the front support arm 28, so as to satisfy that the front end of the support arm 28 can adsorb the glass body 7;

[0042] There is a storage cavity inside the blanking cylinder 33, which is convenient for storing the sleeve rod 35 and the spacer rubber ring.

[0043] The clamping member includes an extension frame 36 fixedly arranged at one end of the moving platform 32 away from the positioning frame 37. A clamping rod 34 is inserted inside the extension frame 36. A clamping hole 38 for the clamping rod 34 to slide through is formed through the inside of the sleeve rod 35;

[0044] Refer to the attached instructions Figure 7 It can be seen that the purpose of the movable insertion of the clamping hole 38 and the clamping rod 34 is to facilitate the upper and lower removal of the sleeve rod 35. During use, the spacer rubber ring is sleeved on the outer surface of the sleeve rod 35, and then placed in the middle of the blanking cylinder 33. Through the positioning of the clamping rod 34, the sleeve rod 35 can be flexibly installed inside the blanking cylinder 33.

[0045] The lifting member includes guiding grooves respectively formed on both sides inside the bottom cylinder 40. Arc-shaped sleeves 43 are arranged at both outer ends of the bottom cylinder 40 and inside the guiding grooves. Connecting blocks 41 are slidably installed inside the two guiding grooves. Arc-shaped rods 39 are arranged at the lower ends of the two connecting blocks 41. A U-shaped rod 44 is commonly arranged at the upper ends of the two connecting blocks 41. A mounting head 45 is sleeved in the middle of the outer side of the U-shaped rod 44. A cylinder 42 is arranged at the upper end of the mounting head 45. The cylinder 42 is fixedly arranged inside the sleeve rod 35. The two arc-shaped rods 39 are in sliding contact with the inner wall of the bottom cylinder 40;

[0046] Refer to the attached instructions Figure 7 、Figure 8 and Figure 9 It can be seen that the arc-shaped sleeve 43 can clamp the bottom cylinder 40 provided with two sets of guide grooves;

[0047] By setting the air cylinder 42, the movement of the U-shaped rod 44 can be driven inside the sleeve rod 35, so that the connecting block 41 and the arc-shaped rod 39 move upward, causing the spacer rubber ring originally in contact with the outside of the arc-shaped rod 39 to move into the lower material cylinder 33. As the arc-shaped rod 39 gradually moves upward, the arc-shaped rod 39 contacts the lower edge of the lower material cylinder 33. During the extrusion contact process, the spacer rubber ring below the outside of the arc-shaped rod 39 can fall off from the arc-shaped rod 39, and the spacer rubber ring is positioned on the surface of the corresponding glass body 7. The arc-shaped rod 39 can be made of a resilient material such as a spring rod or a rubber rod for use.

[0048] The carriage 13 at the screw rod 11 inside the corresponding frame base 10 is in threaded cooperation with the screw rod 11, and the carriage 13 inside the other set of frame bases 10 is in sliding cooperation with the guide rod 22. One end of the screw rod 11 penetrates through the outside of the corresponding frame base 10 and is connected with a second motor 15. The second motor 15 is fixedly installed on the outer wall of the corresponding frame base 10. At both sides of one end of the belt conveyor 9 and corresponding to the position of the L-shaped frame 3, clamping blocks 14 are fixedly arranged. The clamping blocks 14 slide on the outside of the L-shaped frame 3;

[0049] Refer to the attached instruction manual Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 It can be seen that after the second motor 15 is connected to an external power source, it can drive the screw rod 11 to rotate. Under the sliding limit of the guide rod 22 corresponding to the carriage 13 in threaded cooperation with the screw rod 11, the two carriages 13 can be driven to move together inside the corresponding frame bases 10, thereby completing the position adjustment of the palletizing.

[0050] Working principle: The roller conveyor 2 can convey the glass body 7 at intervals to the lifting mechanism. Then, driven by the second motor 15, the two sliding frames 13 drive the support arms 28 to approach the glass body 7. Then, under the telescopic drive of the hydraulic cylinder 26, the use height of the support arms 28 is adjusted, so as to meet the use of each negative pressure pump 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. Then, driven by the lifting mechanism, the height of the belt conveyor 9 is reduced, so as to meet the subsequent stacking of the glass body 7. When the suction head 31 adsorbs the next glass body 7, the support arm 28 moves above the roller conveyor 2, and the L-shaped rod 23 at the rear end drives the support rod 27 to move along with the sliding frame 13, corresponding above the placed glass body 7. 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 lift the arc rod 39. Thus, the spacer rubber rings pre-filled inside the blanking cylinder 33 can slide off the outside of the sleeve rod 35. Without the blocking of the arc rod 39, the spacer rubber rings contact the edge of the blanking cylinder 33 as they move up with the arc rod 39, and then slide onto the surface of the glass body 7 by themselves during the extrusion process. Therefore, when the support arm 28 adsorbs the glass body 7, the blanking cylinders 33 at both ends of the support rod 27 also complete the placement of the spacer rubber rings, and the placement positions are accurate, which can greatly improve the stability of stacking the glass body 7. After the stacking on one side of the storage rack 20 is completed, the glass body 7 on the upper surface of the storage rack 20 can be transported to the external transportation mechanism through the belt conveyor 9, and the external transportation mechanism transports the storage rack 20 and the glass body 7 as a whole away.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
