[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 9 As shown in the figure, the present invention provides a technical solution: an automatic plastic sheet sleeving and picking mechanism for a rhinestone hot-fix drill grinding and polishing machine, including: a loading support box 1 placed on one side of the grinding equipment 2; a rotary storage assembly rotatably installed at one end of the loading support box 1, the rotary storage assembly includes four rotatable and switchable rotary storage racks 4, and a driving part is provided at the bottom of the rotary storage rack 4; a picking component is placed on the top of the loading support box 1, the picking component includes a fixed bottom plate 9, a moving part is provided above the fixed bottom plate 9, a T-shaped rotary rack 11 is rotatably arranged on the top of the fixed bottom plate 9, a pick-up vacuum suction cup 12 is fixedly connected to the end of the T-shaped rotary rack 11, and a third cylinder 15 is provided on the top of the fixed bottom plate 9 and above the T-shaped rotary rack 11, and the output end of the third cylinder 15 is fixedly connected with a second limit insertion plate 16 for separating the plastic sheet; a conveying and loading component is placed on the top of the loading support box 1, and the conveying and loading component includes a belt conveyor 17 and a loading vacuum suction cup 21 for moving the loading.

[0031] It should be noted that the utility model is provided with a PLC controller and an operation panel. The plastic suction sheet to be polished is placed in the rotary storage rack 4. Under the action of the driving part, the rotary storage rack 4 is rotated to the lower part of the material taking assembly. The material taking assembly drives the fixed bottom plate 9 to move downward. When the fixed bottom plate 9 contacts the plastic suction sheet and presses it, the third cylinder 15 drives the L-shaped second limit insertion plate 16 to contract. The second limit insertion plate 16 is inserted into the bottom of the plastic suction sheet. The first cylinder 10 is used to push the T-shaped rotary frame 11 to drive the material taking vacuum suction cup 12 to rotate, so that the material taking vacuum suction cup 12 adsorbs the plastic suction sheet. When the material taking assembly lifts the plastic suction sheet, the second cylinder 13 drives the first limit insertion plate 14 to be inserted into the bottom of the adsorbed plastic suction sheet to prevent the second layer of plastic suction sheet from being lifted. Then the material taking assembly moves the plastic suction sheet to the belt conveyor 17 and conveys it forward. The feeding vacuum suction cup 21 cooperates with the first linear module 20 to lift it and place it on the turntable 27 for one week of grinding and polishing.

[0032] Please refer to Figure 4 、 6 As shown in FIGS. 7 and 9, it further includes a material receiving support box 23. A horizontally arranged second linear module 24 is fixedly connected to the top of the material receiving support box 23. A vertically arranged third linear module 25 is fixedly connected to the moving slide of the second linear module 24. A blanking vacuum suction cup 26 is fixedly connected to the moving slide of the third linear module 25 through a cross beam. A plurality of rotatable turntables 27 are rotatably arranged in the middle of the grinding device 2. A plurality of limit blocks 28 are fixedly connected to the bottom of the turntable 27. A separation ring 29 is sleeved outside the turntable 27 and above the limit block 28. A driving plate 31 is arranged below the separation ring 29. A fifth cylinder 30 is fixedly connected to the middle of the grinding device 2. The output end of the fifth cylinder 30 is fixedly connected to the driving plate 31. A sixth cylinder 32 is fixedly connected to the side of the grinding device 2 where the material is fed. The output end of the sixth cylinder 32 is fixedly connected to a second pressing roller 33, which is used to drive the second pressing roller 33 to roll the material again before grinding, so that the material is in complete contact with the turntable 27. A fixed frame 34 is fixedly connected to one side of the grinding device 2. A sliding rod 36 is slidably connected to the middle of the fixed frame 34. A brake pad 37 for braking the turntable 27 is fixedly connected to the end of the blanking vacuum suction cup 26. A return spring 35 is sleeved outside the sliding rod 36 and between the fixed frame 34 and the brake pad 37.

[0033] It should be noted that the plastic suction sheet of the present utility model rotates around its own axis while revolving in the middle of the grinding device 2. When the grinding is completed, the grinding device 2 drives the plastic suction sheet to rotate to the material taking position. At this time, the turntable 27 with the plastic suction sheet contacts the brake pad 37, and the return spring 35 pushes the brake pad 37 to make it in extrusion contact with the side of the rotating seat at the bottom of the turntable 27. Under the action of friction, the turntable 27 stops rotating. The second linear module 24 drives the blanking vacuum suction cup 26 to move horizontally to the top of the turntable 27 through the third linear module 25 and the cross beam. The third linear module 25 drives the blanking vacuum suction cup 26 to move downward to contact and adsorb the plastic suction sheet. After adsorption and fixation, the fifth cylinder 30 moves upward from the bottom of the separation ring 29 through the driving plate 31, so as to lift the separation ring 29 through the driving plate 31. The separation ring 29 separates the plastic suction sheet at the top from the turntable 27. The third linear module 25 lifts the plastic suction sheet through the cross beam and the blanking vacuum suction cup 26. After the lifting is completed, the second linear module 24 moves the blanking vacuum suction cup 26 to the material receiving position. The blanking vacuum suction cup 26 stops adsorbing, and under the action of gravity, it falls into the material receiving position.

[0034] Please refer to Figure 1 、 2 As shown in FIGS. 3, the driving part includes a driving motor 3 fixedly connected inside the feeding support box 1. The driving motor 3 is fixedly connected to the rotating storage rack 4 through a gear set. A servo electric cylinder 5 is fixedly connected to one side of the inside of the feeding support box 1 close to the belt conveyor 17. The output end of the servo electric cylinder 5 is fixedly connected with a pushing plate 6.

[0035] It should be noted that the gear set of the present utility model includes a large gear and a small gear that mesh with each other. The driving motor 3 is fixedly connected to the small gear. The rotating storage rack 4 is rotatably installed on the top of the feeding support box 1, and the bottom of the rotating storage rack 4 is fixedly connected to the large gear through a rotating shaft. The driving motor 3 drives the rotating storage rack 4 to rotate to the position of the servo electric cylinder 5 through the gear set. The servo electric cylinder 5 drives the pushing plate 6 to rise. The pushing plate 6 pushes up the materials inside the rotating storage rack 4, so that the plastic suction sheets rise layer by layer, and the top plastic suction sheet contacts the material taking vacuum suction cup 12. When there is no plastic suction sheet in one of the storage positions of the rotating storage rack 4, the servo electric cylinder 5 drives the pushing plate 6 to reset, and the driving motor 3 drives the rotating storage rack 4 to rotate, so that another storage position is located above the pushing plate 6.

[0036] Please refer to Figure 2 、 3As shown in FIGS. 5, a second cylinder 13 is fixedly connected to the outside of the loading support box 1 and above the pushing plate 6. The output end of the second cylinder 13 is fixedly connected with a first limiting insertion plate 14. A first cylinder 10 is rotatably connected to the middle of the fixed bottom plate 9, and the output end of the first cylinder 10 is rotatably connected to the middle of the T-shaped rotating frame 11. The moving part includes a transverse linear module 7 horizontally fixedly connected to the top of the loading support box 1. A longitudinal linear module 8 is arranged on one side of the transverse linear module 7. The moving slide of the longitudinal linear module 8 is fixedly connected to the moving slide of the transverse linear module 7, and the bottom of the longitudinal linear module 8 is fixedly connected to the fixed bottom plate 9.

[0037] It should be noted that when the present utility model takes materials, the transverse linear module 7 drives the longitudinal linear module 8 to move horizontally, and the longitudinal linear module 8 drives its moving slide to move. Under the reaction force of the force, the longitudinal linear module 8 drives the fixed bottom plate 9 to move up and down along the Z axis. When the fixed bottom plate 9 moves downward to a specified position, the fixed bottom plate 9 contacts the plastic suction sheet that rises from the bottom. The third cylinder 15 drives the second limiting insertion plate 16 to move towards the middle of the fixed bottom plate 9. The second limiting insertion plate 16 inserts into the bottom of the top plastic suction sheet and lifts the plastic suction sheet from one side. At the same time, the first cylinder 10 extends to drive the T-shaped rotating frame 11 to rotate. While the T-shaped rotating frame 11 rotates, it drives the material-taking vacuum suction cup 12 to rotate. The material-taking vacuum suction cup 12 contacts the top plastic suction sheet and adsorbs it. The second cylinder 13 drives the first limiting insertion plate 14 to insert from the position where the second limiting insertion plate 16 lifts. The longitudinal linear module 8 lifts the plastic suction sheet through the material-taking vacuum suction cup 12 and the second limiting insertion plate 16. Then the transverse linear module 7 drives the material-taking vacuum suction cup 12 to move horizontally to the top of the belt conveyor 17 through the longitudinal linear module 8. Then the longitudinal linear module 8 drives the material-taking vacuum suction cup 12 to move downward. The third cylinder 15 drives the second limiting insertion plate 16 to reset. When the material-taking vacuum suction cup 12 stops adsorbing, the plastic suction sheet falls onto the belt conveyor 17 under the action of gravity, and the belt conveyor 17 drives the plastic suction sheet to be conveyed forward.

[0038] Please refer to Figure 3 、 5 As shown in FIGS., the conveying and loading assembly further includes a first linear module 20 fixedly connected to the top of the loading support box 1. A lifting cylinder is fixedly connected to the outside of the moving slide of the first linear module 20.

The ends and both sides of the belt conveyor 17 are fixedly connected with fourth cylinders 18, and the output ends of the fourth cylinders 18 are fixedly connected with third limiting insertion plates 19.

[0039] It should be noted that when the plastic suction sheet of the present utility model is conveyed to the end of the belt conveyor 17, under the action of the position sensor, the belt conveyor 17 stops working, and the end of the belt conveyor 17 and the No. 4 cylinder 18 on the side work simultaneously. The No. 4 cylinder 18 inserts the L-shaped No. 4 cylinder 18 into the bottom of the plastic suction sheet to position the plastic suction sheet and separate its bottom from the belt conveyor 17. The driving slide of the No. 1 linear module 20 drives the lifting cylinder to move horizontally. The lifting cylinder drives the feeding vacuum suction cup 21 to move to the top of the plastic suction sheet. The lifting cylinder drives the feeding vacuum suction cup 21 to contact and adsorb the plastic suction sheet downward, and then the lifting cylinder lifts the plastic suction sheet. The No. 1 linear module 20 drives the feeding vacuum suction cup 21 to move to the middle of the grinding device 2 and above the feeding turntable 27. The lifting cylinder drives the plastic suction sheet to be sleeved downward on the top of the turntable 27. Then the discharging vacuum suction cup 26 stops adsorbing and rises under the action of the lifting cylinder. Then the No. 1 pressing roller 22 moves downward under the action of the cylinder, so that the No. 1 pressing roller 22 contacts the plastic suction sheet on the top of the turntable 27. The No. 1 linear module 20 drives the No. 1 pressing roller 22 to move horizontally. The No. 1 pressing roller 22 rolls and flattens the plastic suction sheet, extruding the bottom bubbles, making it fit and flat with the turntable 27 more closely.
