Description

Technical Field

[0001] The invention relates to the technical field of artificial diamond processing, and in particular to an automatic grinding and polishing machine for artificial diamond cultivation. Background Art

[0002] Artificial diamonds, also known as cultured diamonds, are polycrystalline diamonds formed by the aggregation of diamond crystals with a diameter of 10 to 30 nanometers. They have the same physical and chemical properties as natural diamonds. After the initial cultivation of artificial diamonds, artificial diamonds may need to be cut and polished to form the desired shape and size. This includes cutting the diamond rough into different shapes (such as cylindrical, square, heart-shaped, etc.), among which the diamond rough cut into a cylindrical shape can be convenient for subsequent processing and treatment into specific facets and angles. The grinding and polishing process is a crucial step, which is directly related to the final quality and market value of the diamond. With the advancement of science and technology and the development of automation technology, some automated grinding and polishing equipment has begun to appear on the market. However, these devices still have many problems in practical applications. According to the "Automated Grinding and Polishing Machine for Artificial Diamond Cultivation" provided by China Patent Authorization Announcement No. CN202211231540.1, when working, the cut round diamond needs to be placed on the upper end of the support plate, and then the round diamond is clamped and fixed by a three-claw clamping mechanism for grinding. Not only can the flat surface of the round diamond be automatically ground, but also the curved surface of the round diamond can be automatically ground. The round diamond does not need to be transferred and transported to complete the grinding of the round diamond, which saves time in the transfer process, has high work efficiency, low usage limitations, and is easy to use.

[0003] However, when the round diamond is clamped and fixed by a three-jaw clamping mechanism and then polished, the contact surface of the three-jaw clamping mechanism and the round diamond cannot be contacted and polished by the polishing mechanism, making it difficult to fully polish all parts of the diamond, resulting in insufficient polishing of the artificial diamond and reduced quality of the artificial diamond.

[0004] For this reason, it is necessary to design an automatic grinding and polishing machine that can cut artificial diamonds and achieve all-round grinding to solve the problem. Summary of the invention

[0027] The two arc-shaped splints 624 are symmetrically arranged, and the opposite ends of the two arc-shaped splints 624 are provided with a plurality of grooves, cylindrical artificial diamonds.

[0028] Embodiment 2, on the basis of embodiment 1, the adjusting grinding and polishing mechanism 3 includes a double-axis telescopic cylinder 31 fixed on the top of the grinding and polishing bin 5, the telescopic rod of the double-axis telescopic cylinder 31 passes through the grinding and polishing bin 5, and is fixed with a connecting plate 32, a driving motor 33 is fixed at the bottom of the connecting plate 32, and the output shaft at the bottom of the driving motor 33 is transmission-connected with an adjusting grinding mechanism 34.

[0031] Specifically, the adjusting bolt 343 is extended by rotating the tool, driving the vertical mounting plate 342 to move, and the stability is maintained by the guide rod. The exposed length of the abrasive 344 on the upper mounting plate 341 is the same as the diameter of the cylindrical artificial diamond, so that cylindrical artificial diamonds of different diameters can be ground and polished.

[0032] Embodiment 3, based on embodiment 1, the lifting blocking structure 10 includes two lifting cylinders 102 with bearing seats installed on the upper and lower rotating shafts, baffle 2 101 is fixed on the top of the two lifting cylinders 102 through the bearing seats, and the bottom of the two lifting cylinders 102 is fixedly connected to the grinding and polishing machine body 1 through the bearing seats.

[0033] Specifically, after the transmission clamping device 6 returns to the initial position, the PLC controls the electrical box 2 to control the external air pump station to supply air to the two lifting cylinders, and controls the two lifting cylinders to drive the baffle 2 101 to shrink until the distance between the baffle 1 8 and the connecting tube 621 is greater than the height of the cylindrical artificial diamond. At this time, the lifting cylinder close to the discharge port 12 is controlled separately to continue to shrink, and the baffle 2 101 tilts downward close to the bottom of the discharge port 12, and cooperates with the two mounting vertical plates 71 to form an inclined channel. At this time, the PLC controls the electrical box 2 to gradually control the electromagnet push rods 622 on the multiple adjustment fixtures 62 to be energized, so that the cylindrical artificial diamond falls onto the baffle 2 101, and is guided to be discharged from the discharge port 12 through the inclined channel. The staff only needs to accept the polished cylindrical artificial diamond at the discharge port 12.

[0034] Working principle: When in use, the lifting and blocking structure 10 is raised by controlling the electric box 2 through the PLC: controlling the external air pump station to synchronously supply air to the two lifting cylinders, and the two lifting cylinders extend to drive the baffle plate 2 101 to rise close to the transmission clamping device 6; Install the cut cylindrical artificial diamonds on the transmission clamping device 6: Place the cylindrical artificial diamonds into the connecting tubes 621 of the adjusting clamps 62 respectively, and the bottom of each cylindrical artificial diamond contacts the baffle 2 101 for limiting; Automatic grinding is performed by controlling the electric box 2 through the PLC. The electric box 2 controls the two electromagnet push rods 622 of each adjusting fixture 62 to be powered off. The two electromagnet push rods 622 extend out, driving the two arc-shaped clamping plates 624 to clamp the cylindrical artificial diamond. The two arc-shaped clamping plates 624 are arranged to have a large contact friction with the groove and the circular artificial diamond. Then the reduction motor 72 is controlled to work, and the reduction motor 72 drives one of the driving gears 7. Through the cooperation of multiple pulleys of the synchronous belt, the multiple driving gears 7 on one mounting vertical plate 71 are the driving gear set, and the multiple driving gears 7 on the other mounting vertical plate 71 are the driven gear set. The driving gear set is meshed with a set of racks 64 of the connecting frame 61 for transmission, and the other set of racks 64 is meshed with the driven gear set for transmission. The multiple cylindrical artificial diamonds in the connecting frame 61 move toward the grinding and polishing bin 5. The connecting frame 61 rolls in the two side slide grooves 41 through four moving wheels 63 to maintain stable movement. When the first cylindrical artificial diamond enters the grinding and polishing bin 5, the photoelectric sensor 51 detects the entry of the cylindrical artificial diamond, and the photoelectric sensor 51 sends a signal to the PLC control box 2. The PLC control box 2 controls the reduction motor 72 to stop working. At this time, the cylindrical artificial diamond and the adjustment and polishing mechanism 34 are on the same vertical center line. At this time, the PLC controls the electric box 2 to control the driving motor 33 to drive the adjusting and polishing mechanism 34 to rotate at a high speed, and controls the external air pump station to supply air to the double-axis telescopic cylinder 31 to extend it. The double-axis telescopic cylinder 31 drives the driving motor 33 and the adjusting and polishing mechanism 34 on the connecting plate 32 downward, and the abrasives 344 on the upper mounting plate 341 and the vertical mounting plate 342 form a cylindrical polishing shape as they rotate at a high speed, and as they move downward, they contact and polish the outer surface of the cylindrical artificial diamond to keep it smooth. During the polishing process, the PLC controls the electric box 2 to control the external water pump to supply water to the two water outlet pipes 52, and the water is sprayed from multiple nozzles. The wastewater flows down the moving groove 4 into the collecting pool 9 inside the grinding and polishing machine body 1 for collection. As it moves downward, the abrasive 344 on the upper mounting plate 341 contacts and polishes the top of the cylindrical artificial diamond. A pressure sensor is installed on the connecting plate 32 and is electrically connected to the PLC control electric box 2 for detecting the pressure of contact with the cylindrical artificial diamond. When the abrasive 344 on the upper mounting plate 341 contacts and polishes the top of the cylindrical artificial diamond and the grinding force reaches the set value, the pressure sensor sends a signal to the PLC control electric box 2, and the PLC control electric box 2 controls the driving The driving motor 33 works and controls the double-axis telescopic cylinder 31 to return to its original position, completing most of the grinding and polishing on the cylindrical artificial diamond. The PLC controls the electric box 2 to continue to control the reduction motor 72 to drive the active gear set, thereby driving the transmission clamping device 6 to move in the moving groove 4, driving the clamped cylindrical artificial diamond to move, so that the next cylindrical artificial diamond enters the grinding and polishing bin 5 for processing, until all the cylindrical artificial diamonds are polished. The transmission clamping device 6 moves to the tail of the grinding and polishing machine body 1, and the PLC controls the electric box 2 to control the reduction motor 72 to stop working, and then controls the electromagnet push rod 62 of each adjustment fixture 62 2 is powered on, so that the electromagnet push rod 622 contracts, and the two arc-shaped clamping plates 624 loosen the cylindrical artificial diamond, and the cylindrical artificial diamond falls downward to contact and support the baffle 1 8. At this time, the cylindrical artificial diamond is flush with the top of the connecting tube 621. The PLC controls the electric box 2 to control the two electromagnet push rods 622 of each adjusting fixture 62 to cut off the power, and the two electromagnet push rods 622 extend to drive the two arc-shaped clamping plates 624 to clamp the cylindrical artificial diamond, and then gradually control the steering gear 623 of each adjusting fixture 62 to flip 180 degrees, so that the unpolished part of the cylindrical artificial diamond is exposed upward; The PLC controls the motor to control the reduction motor 72 to reverse, controls the reduction motor 72 to drive the driving gear set, thereby driving the transmission clamping device 6 to move in the moving groove 4, driving the clamped cylindrical artificial diamond to move toward the grinding and polishing bin 5, and multiple cylindrical artificial diamonds gradually re-enter the grinding and polishing bin 5, and stop through the induction of the photoelectric sensor 51, and drives the adjustment grinding and polishing mechanism 3 downward, so that the high-speed rotating adjustment grinding mechanism 34 grinds the cylindrical artificial diamond, thereby fully grinding and polishing the cylindrical artificial diamond, and the grinding and polishing efficiency is high; Therefore, after the cylindrical artificial diamond is completely polished, the PLC control motor continues to control the reduction motor 72 to reverse, and controls the reduction motor 72 to drive the active gear set, so that it drives the drive transmission clamping device 6 to return to the initial position. At this time, the PLC controls the electrical box 2 to control the reduction motor 72 to stop working, and then controls the external air pump station to supply air to the two lifting cylinders, and controls the two lifting cylinders to drive the baffle 2 101 to shrink until the distance between the baffle 1 8 and the connecting tube 621 is greater than the height of the cylindrical artificial diamond. At this time, the lifting cylinder close to the discharge outlet 12 is controlled separately to continue to shrink, and the baffle 2 101 tilts downward close to the bottom of the discharge outlet 12, and cooperates with the two mounting vertical plates 71 to form an inclined channel. At this time, the PLC controls the electrical box 2 to gradually control the electromagnet push rods 622 on the multiple adjustment fixtures 62 to be energized, so that the cylindrical artificial diamond falls onto the baffle 2 101, and is discharged from the discharge outlet 12 through the inclined channel. The staff only needs to accept the polished cylindrical artificial diamond at the discharge outlet 12.
