Specific embodiments

[0028] 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.

[0029] Please refer to Figures 1-8, the present invention provides a technical solution: an automated intelligent crystal grinding and polishing machine, comprising: a circular frame 1 composed of a metal ring and support legs, a driving part for driving the rotary workbench 2 to rotate at a fixed angle is arranged inside the circular frame 1, and a rotary workbench 2 is rotatably installed in the middle of the circular frame 1; a rubber tooling table 3 with a through hole in the middle, the rubber tooling table 3 is formed by bonding a metal plate and a rubber pad, the rubber tooling table 3 is rotatably installed on the top of the rotary workbench 2, hollow drive pipes 22 are fixedly connected to the bottom of the rubber tooling table 3, the hole in the middle of the rubber tooling table 3 is concentric with the 1 hollow drive pipe 22, the hollow drive pipe 22 is rotatably connected to the rotary workbench 2 through a bearing, a fourth motor 23 for driving its self-rotation is arranged on the outside of the hollow drive pipe 22, and an air extraction part is arranged at the bottom of the hollow drive pipe 22 for fixing materials under negative pressure; there are three processing parts and they are arranged above the rubber tooling table 3, the processing part includes a transmission shaft 17 and a cylinder 11 for adjusting the lifting of the transmission shaft 17, and a processing disc 18 for grinding and polishing is installed at the bottom of the transmission shaft 17; a loading and unloading assembly is arranged on one side of the circular frame 1, the loading and unloading assembly includes a sponge vacuum chuck 34 that can rotate and lift, a loading support disc 27 and a receiving support disc 30 with a second spring 29 at the bottom, the loading support disc 27 and the receiving support disc 30 are respectively connected to both ends of a steel wire rope 35 for realizing equal lifting heights of the loading support disc 27 and the receiving support disc 30, and a belt linear module 31 for driving the lifting of the loading support disc 27 is arranged on one side of the loading support disc 27.

[0030] It should be noted that the present invention is equipped with a PLC controller and an operation panel. Control switches for various components are provided on the operation panel. By operating the panel, the belt linear module 31 is controlled to move the lifting cylinder 37 to the lowest position. Flaky materials with crystals are stacked on the top of the feeding support plate 27, so that the sponge vacuum suction cup 34 can contact the material at the top after rotating and descending. When the feeding support plate 27 is at the lowest position, under the action of the second spring 29, the receiving support plate 30 is at the highest position, enabling the sponge vacuum suction cup 34 to rotate reciprocally by 90 degrees to achieve loading and unloading. After the receiving rotation, it can be placed above the receiving support plate 30. The belt linear module 31 drives the feeding support plate 27 to rise upward by the thickness of one material for feeding. The feeding support plate 27 pulls the receiving support plate 30 downward by the thickness of one material through the steel wire rope 35 for receiving, so that the materials on the top of the feeding support plate 27 and the materials on the top of the receiving support plate 30 can both cooperate with the sponge vacuum suction cup 34. When the material is placed on the top of the rubber tooling table 3, the air extraction part conducts air extraction treatment on the hollow transmission pipe 22. Under the negative pressure, the material is tightly adsorbed on the top of the rubber tooling table 3. The driving part drives the rubber tooling table 3 to rotate counterclockwise in turn to the lower part of the subsequent processing part, and the processing disk 18 driven by the cylinder 11 contacts the material. When the material rotates one week along with the rotary worktable 2, the grinding and polishing of the material are realized. The loading and unloading assembly receives and then discharges the material, and circulates in this way to realize automatic grinding and polishing processing.

[0031] As Figure 5 、 6 shown, the driving part includes a third motor 21 fixedly connected to the inner wall of the annular frame 1. The output end of the third motor 21 is fixedly connected with a driving gear. A transmission gear ring 20 is fixedly connected to the bottom of the rotary worktable 2. The transmission gear ring 20 is meshed and connected with the driving gear.

[0032] It should be noted that magnets are installed at the positions of the rubber tooling table 3 corresponding to the bottom of the rotary worktable 2 of the present invention. Hall sensors are fixedly connected to the inner wall of the annular frame 1 corresponding to the positions of the support pipes 6. The third motor 21 drives the transmission gear ring 20 to rotate through the driving gear. The transmission gear ring 20 drives the rotary worktable 2 to rotate. The rotary worktable 2 drives the material to revolve through the rubber tooling table 3, facilitating the switching of the processing position. When the magnet approaches and cooperates with the Hall sensor, the Hall sensor transmits the signal to the controller, and the controller controls the third motor 21 to stop rotating, thereby realizing fixed-angle rotation, so that the rotary worktable 2 can accurately stop directly below the support pipe 6, facilitating the grinding and polishing of the material on the top of the rubber tooling table 3 by the processing disk 18.

[0033] As Figure 5 、 6As shown in the figure, the air extraction part includes a vacuum pump 24 fixedly connected to the bottom of the annular frame 1. The hollow drive pipe 22 is rotatably connected to the rotary table 2. The fourth motor 23 is fixedly connected to the bottom of the rotary table 2 through a bracket. The fourth motor 23 is drivingly connected to the hollow drive pipe 22 through a gear set. The bottom of the hollow drive pipe 22 is connected with an air pipe through a rotary joint, and the other end of the air pipe is connected to the vacuum pump 24 through a rotary joint.

[0034] It should be noted that the gear set of the present invention is two meshing spur gears, which are respectively connected to the fourth motor 23 and the hollow drive pipe 22. The fourth motor 23 drives the hollow drive pipe 22 to rotate through the gear set. The hollow drive pipe 22 drives the material to rotate by itself through the rubber tooling table 3, and its rotation direction is opposite to the rotation direction of the processing disk 18. A cross plate is welded to the bottom of the annular frame 1, and the vacuum pump 24 is fixedly connected to the top of the cross plate. A rotary joint is installed at the air extraction end of the vacuum pump 24. One end of the rotary joint is fixedly connected to the cross plate, and a plurality of air pipes made of hard plastic or steel are equidistantly connected to the outside of its free end. The other end of the air pipe is connected to the rotary joint at the bottom of the hollow drive pipe 22. Negative pressure is extracted from the hollow drive pipe 22 through the vacuum pump 24 and the air pipe, so as to ensure that the hollow drive pipe 22 does not affect the formation of negative pressure on the hollow drive pipe 22 during the revolution and rotation of the hollow drive pipe 22. Solenoid valves are provided in the middle of the air pipes, and the solenoid valves are connected to an external power supply through an electric slip ring.

[0035] As Figure 2 、 3 shown in the figure, a three-quarter circle structure of the protective support cover 4 is provided on the top of the annular frame 1, and a water outlet pipe 5 for spraying water on the rubber tooling table 3 is provided on the inner wall of the protective support cover 4.

[0036] It should be noted that the notch of the protective support cover 4 of the present invention is the loading and unloading position. When the rotary table 2 drives the rubber tooling table 3 to rotate to the notch position of the protective support cover 4, loading and unloading operations can be performed on the top of the rubber tooling table 3. And a water outlet pipe 5 is installed below each processing part. A plurality of through holes are opened in the middle of the rotary table 2, and a ring-shaped recovery groove is provided at the position of the corresponding through hole on the inner wall of the annular frame 1 for dust reduction treatment at the grinding and polishing position.

[0037] As Figure 1 、 2, as shown in Fig. 4, the processing section further includes three support pipes 6 fixedly connected to the top of the protective support cover 4 at equal intervals. A transmission shaft 17 is provided in the middle of each support pipe 6. Short straight gears 14 are arranged on the outer sides of the transmission shafts 17. Long straight gears 13 are meshed with the outer sides of the short straight gears 14. When the transmission shafts 17 rise or fall, the short straight gears 14 slide up and down and are in transmission connection with each other. The processing discs 18 at the ends of the transmission shafts 17 are, in counterclockwise order, a grinding disc, a polishing disc, and a polishing disc. Two fixing plates 7 are fixedly connected to the top of each support pipe 6. A plurality of limiting support rods 8 are fixedly connected between the two fixing plates 7. A lifting pressure plate 10 with a convex structure is slidably connected to the outside of two of the limiting support rods 8. A first spring 9 is installed below the lifting pressure plate 10. A cylinder 11 is fixedly connected to the fixing plate 7. The output end of the cylinder 11 is fixedly connected to the lifting pressure plate 10. A second motor 19 is fixedly connected to the top of the protective support cover 4. A rotating shaft is rotatably connected between the output end of the second motor 19 and the topmost fixing plate 7. Each long straight gear 13 is rotatably installed between the two fixing plates 7. The top of the long straight gear 13 is in transmission connection with the rotating shaft through a transmission belt assembly 16.

[0038] It should be noted that in the present invention, the second motor 19 drives the three long straight gears 13 to rotate simultaneously through the transmission belt assembly 16. The long straight gears 13 drive the transmission shafts 17 to rotate through the short straight gears 14. When the rotary table 2 drives the rubber tooling table 3 to rotate to the bottom of the processing disc 18, the cylinder 11 drives the lifting pressure plate 10 to move downward along the limiting support rod 8. The lifting pressure plate 10 drives the transmission shaft 17 to move downward. While moving downward, the transmission shaft 17 drives the short straight gear 14 to slide on the outside of the long straight gear 13, and the long straight gear 13 and the short straight gear 14 are always in a meshed state, so as to realize the rotation of the processing disc 18 while descending. Its rotation direction is opposite to that of the rubber tooling table 3. And three processing discs 18 are driven by one motor to perform simultaneous processing. The three processing discs 18 are, in counterclockwise order, a grinding disc, a rough polishing disc, and a fine polishing disc, so as to realize the processing procedure of grinding and then polishing the material. Under the action of the timer, the cylinder 11 drives the lifting pressure plate 10 to move upward along the limiting support rod 8. At this time, the first spring 9 resets, and the lifting pressure plate 10 pulls the rotating transmission shaft 17 upward, so as to separate the processing disc 18 from the rubber tooling table 3, which is convenient for the rotary table 2 to drive the rubber tooling table 3 to perform position switching, and is convenient for the corresponding processing or the picking and placing of the material.

[0039] As Figure 1 , 7As shown in the figure, the loading and unloading component further includes a support base 25. A support frame 36 is fixedly connected to the top of the support base 25. Two lifting cylinders 37 are fixedly connected to the side of the support frame 36. The output end of the lifting cylinder 37 is fixedly connected to a lifting slide plate 12. The support frame 36 is slidably connected to the lifting slide plate 12. A first motor 15 is fixedly connected to the bottom of the lifting slide plate 12. The output end of the first motor 15 is fixedly connected to a rotating shaft 38. A swing arm 33 with a right-angled "L" structure is fixedly connected to the outside of the rotating shaft 38. Sponge vacuum suction cups 34 are fixedly connected to both ends of the swing arm 33.

[0040] It should be noted that a vacuum generator connected to the sponge vacuum suction cup 34 is provided at the top of the swing arm 33 of the present invention. The loading support plate 27 and the unloading support plate 30 are symmetrical about the support frame 36, and the top of the unloading support plate 30 and the topmost material on the loading support plate 27 are at the same height as the top of the rubber tooling table 3. During processing, the two ends of the swing arm 33 face the rubber tooling table 3 and the loading support plate 27 respectively. When the processed material rotates to the notch position of the protective support cover 4, the lifting cylinder 37 drives the lifting slide plate 12 to move downward along the support frame 36. The lifting slide plate 12 drives the sponge vacuum suction cup 34 to move downward through the rotating shaft 38 and the swing arm 33, so that the sponge vacuum suction cup 34 contacts and adsorbs the processed material on the top of the rubber tooling table 3 and the unprocessed material at the topmost of the lifting cylinder 37 respectively. After the adsorption is completed, the lifting cylinder 37 drives the swing arm 33 to rise through the lifting slide plate 12 and the rotating shaft 38. Then, the first motor 15 drives the swing arm 33 to rotate through the rotating shaft 38, so that the sponge vacuum suction cup 34 rotates 90 degrees around the rotating shaft 38, placing the processed material on the top of the unloading support plate 30 and the unprocessed material on the rubber tooling table 3. The lifting cylinder 37 drives the swing arm 33 to descend again and controls the sponge vacuum suction cup 34 to stop adsorbing, so as to place the materials corresponding to the rubber tooling table 3 and the unloading support plate 30. The air extraction part fixes the material on the top of the rubber tooling table 3, and then the first motor 15 drives the swing arm 33 to rotate to the initial position.

[0041] Such as Figure 1 、 7, as shown in Fig. 8, three feeding limit rods 26 are fixedly connected to the top of the support base 25. The first motor 15 is slidably connected to the feeding limit rods 26. The belt linear module 31 is fixedly connected to the top of the support base 25 and on the side close to the feeding limit rods 26. The feeding support disc 27 is fixedly connected to the moving slide of the belt linear module 31. Three receiving limit rods 28 are fixedly connected to the top of the support base 25 at equal intervals on the side far from the feeding limit rods 26. The receiving support disc 30 is slidably installed outside the receiving limit rods 28. The second spring 29 is located below the receiving support disc 30 and sleeved outside the receiving limit rods 28. A limit frame 32 is fixedly connected to the top of the support base 25 on the side close to the receiving support disc 30. The receiving support disc 30 is slidably connected to the limit frame 32. Pulleys for guiding the steel wire rope 35 are provided at the bottom of the limit frame 32 and the top of the support base 25 to make the steel wire rope 35 move along a U-shaped route.

[0042] It should be noted that the belt linear module 31 of the present invention includes a bracket with a guide rail, a moving slide slidably arranged on the guide rail, a belt for driving the moving slide to move, and a servo motor for driving the belt to rotate. A plurality of through holes are provided at equal intervals in the middle of the receiving support disc 30. A water collection tank is installed at the top of the support base 25 and below the receiving support disc 30. A protective plate is provided at the position corresponding to the receiving support disc 30 on the top of the support base 25. A plurality of fans for air drying are installed at equal intervals in the middle of the protective plate. The elastic force of the second spring 29 is greater than the total gravity when the receiving support disc 30 is filled with materials at the top. While the swing arm 33 moves downward to discharge materials, the belt linear module 31 drives the feeding support disc 27 to move upward along the feeding limit rods 26 by the thickness of one material. While the feeding support disc 27 moves upward, the steel wire rope 35 is pulled. Under the action of the pulley, the steel wire rope 35 pulls the receiving support disc 30 downward along the receiving limit rods 28, so that the receiving support disc 30 moves downward by the thickness of one material. When the swing arm 33 rotates and resets to the initial position, the height of the material at the top of the feeding support disc 27 is the same as the previous picking height, so as to facilitate picking up the material.
