[0002] Diamond powder refers to diamond particles with a particle size of finer than 54 microns, including single crystal diamond powder and polycrystalline diamond powder. Due to the large output of single crystal diamond powder and its wide application field, the industry generally refers to single crystal diamond powder as diamond powder. Single crystal diamond powder is produced by static pressure method artificial diamond single crystal abrasive, which is crushed and shaped by special process methods of superhard materials. In the production process of diamond powder, it is necessary to sort the diamond powder, extract qualified diamond powder and remove unqualified diamond powder. Screening is the most commonly used method, which is suitable for coarser diamond powder. Diamond powders of different particle sizes are separated by screening through sieves of different apertures.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1-10A diamond micro powder sorting online automatic detection device includes a workbench 1 and a detector arranged on the surface of the workbench. A support column 2 is fixedly connected to the upper surface of the workbench 1. A sliding assembly 3 is slidably arranged on the upper surface of the workbench 1 through the support column 2. The sliding assembly 3 includes a sliding box 301 and a trapezoidal slide rail 302 for sliding the sliding box 301 on the upper end of the support column 2. The trapezoidal slide rail 302 is fixedly connected to the lower surface of the sliding box 301. The sliding box 301 and the trapezoidal slide rail 302 are driven to move by a first driving mechanism 303. The first driving mechanism 303 includes a driving motor fixed to the surface of the support column 2 and a gear fixedly assembled on the output shaft of the driving motor. A rack is fixedly connected to the surface of the sliding box 301, and the rack is meshed with the gear.

[0034] It is understandable that by driving the gear to rotate through the driving motor, the sliding box 301 and the sampling cup 6 are driven to move with the cooperation of the rack, thereby increasing the moving stroke of the sampling cup 6, increasing the working range, and adapting to different working environments.

[0035] Specifically, a guide rod 4 is fixedly connected to the inner wall of the sliding box 301, and a sampling cup 6 is slidably connected to the surface of the guide rod 4 through a sleeve rod 5. The sampling cup 6 and the sleeve rod 5 are driven to move through a second driving mechanism 7. The second driving mechanism 7 includes a driving motor fixed to the upper surface of the sliding box 301 and a gear fixedly assembled on the output shaft of the driving motor. A rack is fixedly connected to the surface of the sleeve rod 5, and the rack is meshed with the gear.

[0036] It can be understood that the gear is driven to rotate by the driving motor, and with the cooperation of the gear and the rack, the sleeve rod 5 is driven to slide on the surface of the guide rod 4, and the sampling cup 6 is transported to the bottom of the discharge port of the sorting equipment. A small amount of sample of the sorted diamond powder is taken through the sampling cup 6 to achieve the purpose of automatic sampling.

[0037] Specifically, an opening and closing assembly 8 for automatically discharging the sampling cup 6 is provided on the lower surface of the sleeve rod 5. The opening and closing assembly 8 includes a tilting rod 801 rotatably connected to the lower surface of the sleeve rod 5 and a bottom plate 802 for sealing the bottom of the sampling cup 6. The bottom plate 802 is fixedly connected to one end of the tilting rod 801. A top block 803 is fixedly connected to the inner wall of the sliding box 301.

Both ends of the elastic plate 804 are respectively fixedly connected to the surface of the tilting rod 801 and the surface of the sleeve rod 5. A limit block 805 for limiting the tilting rod 801 is fixedly connected to the lower surface of the sleeve rod 5. An arc is provided at one end of the tilting plate close to the bottom plate 802 to prevent motion interference with the sliding box 301.

[0038] It can be understood that after the sampling cup 6 is reset by the sleeve rod 5, the top block 803 drives the tilting rod 801 to rotate under the action of the inclined surface, so that the bottom plate 802 opens the bottom of the sampling cup 6, and the sample automatically falls into the container 13. By setting the elastic plate 804, the tilting rod 801 and the bottom plate 802 can be driven to rotate, so that the bottom plate 802 closes the bottom of the sampling cup 6, which is convenient for sampling. Under the action of the limit block 805, the bottom plate 802 can accurately correspond to the sampling cup 6. Specifically, the surface of the support column 2 is rotatably connected to a mounting block 9 via a bearing, and the mounting block 9 is driven to rotate via a third driving mechanism 10. The third driving mechanism 10 includes a driving motor fixed to the surface of the support column 2 and a gear fixedly assembled on the output shaft of the driving motor. A gear ring is fixedly connected to the upper surface of the mounting block 9, and the gear ring is meshed with the gear.

[0039] It can be understood that the gear is driven to rotate by the driving motor, and the mounting block 9 and multiple containers 13 are driven to rotate under the meshing relationship between the gear and the gear ring, so as to facilitate the sampling, testing, brushing and drying work at the same time, thereby improving work efficiency.

[0040] Specifically, the surface of the mounting block 9 is rotatably connected to a connecting frame 11 through a bearing, two thin rods 12 are fixedly connected to the side of the connecting frame 11, and the other ends of the two thin rods 12 are fixedly connected to a vessel 13 for receiving samples. The connecting frame 11 is driven to rotate by a fourth driving mechanism 14, and the fourth driving mechanism 14 includes a driving motor fixed to the surface of the mounting block 9 and a worm fixedly assembled on the output shaft of the driving motor. A worm gear is fixedly assembled on the optical axis surface of the connecting frame 11, and the worm gear and the worm gear are meshed. There are a total of multiple groups of vessels 13, which are distributed in an array on the surface of the mounting block 9.

[0041] It is understandable that the worm is driven to rotate by the driving motor, and the worm and the worm wheel cooperate to make the connecting frame 11 drive the vessel 13 to flip, thereby facilitating the pouring out of the sample and facilitating the cleaning and drying of the vessel 13.

[0042] Specifically, a multi-tooth plate 15 is fixedly connected to the surface of the two thin rods 12, and the tooth surface of the multi-tooth plate 15 faces downward. A lever 16 for moving the multi-tooth plate 15 to generate vibration is fixedly connected to the upper surface of the workbench 1.

[0043] It is understandable that by providing the multi-tooth plate 15 and the lever 16, the container 13 drives the multi-tooth plate 15 to slide across the surface of the lever 16 during rotation, thereby causing the container 13 to vibrate and flatten the sample, facilitating particle size detection.

[0044] Specifically, a funnel 17 for collecting samples is fixedly mounted on the upper surface of the workbench 1 , and a collection box 18 for temporarily storing samples is disposed inside the workbench 1 .

[0045] It is understandable that by providing the funnel 17 and the collection box 18, it is convenient to collect and store the detected diamond powder to avoid waste.

[0046] Specifically, a cleaning box 19 is fixedly connected to the upper surface of the workbench 1, and an opening is provided on the surface of the cleaning box 19 for allowing the utensils 13 to enter and exit. The bottom of the cleaning box 19 is connected to a sewage tank 20 through a hose. The sewage tank 20 is fixedly connected to the side of the workbench 1, and a drain outlet is provided on the surface of the sewage tank 20.

[0047] It is understandable that when the vessel 13 is cleaned, the generated sewage is discharged into the sewage tank 20 through a hose for storage, so as to facilitate centralized treatment.

[0048] Specifically, a brushing assembly 21 is provided inside the cleaning box 19, and the brushing assembly 21 includes a connecting pipe 2101 that slides vertically at the bottom of the cleaning box 19 and a brushing head 2103 for cleaning the utensils 13. A plurality of water outlet holes are provided on the surface of the brushing head 2103, and bristles are provided on the surface. The brushing head 2103 is connected to the upper end of the connecting pipe 2101 through a rotating sealing joint 2102. A blade 2104 is fixedly connected inside the brushing head 2103 for driving the brushing head 2103 to rotate with water flow. A clean water tank 2105 is fixedly connected to the side of the workbench 1. The clean water tank 2105 supplies water to the connecting pipe 2101 through a water pump 2106 and a hose, and a water inlet is provided on the upper surface of the clean water tank 2105.

[0049] It can be understood that the water in the clean water tank 2105 is transported to the scrubbing head 2103 through the hose by the water pump 2106, and the scrubbing head 2103 is driven to rotate through the rotary sealing joint 2102 and the bearing under the action of the blades 2104, thereby scrubbing the used vessel 13 to prevent the residual sample in the vessel 13 from affecting the next use.

[0050] Specifically, a splash-proof assembly 22 is provided on the surface of the cleaning box 19, and the splash-proof assembly 22 includes a baffle plate 2201 for covering the opening, and a through groove for avoiding the two thin rods 12 is provided on the surface of the baffle plate 2201. The baffle plate 2201 slides on the surface of the cleaning box 19, and the baffle plate 2201 is driven to move by two electric push rods. The two ends of the two electric push rods are respectively fixedly connected to the side of the baffle plate 2201 and the side of the cleaning box 19. The inner wall of the baffle plate 2201 is fixedly connected to a connecting rod 2202 for simultaneously driving the scrubbing head 2103 to rise and fall, and the connecting rod 2202 is rotatably connected to the surface of the scrubbing head 2103 through a bearing.

[0051] It is understandable that the electric push rod drives the shielding plate 2201 to rise and close the opening to prevent water from splashing during cleaning. At the same time, the shielding plate 2201 drives the scrubbing head 2103 through the connecting rod 2202 to enter the container 13 for scrubbing.

[0052] Specifically, a drying component 23 for drying the container 13 is fixedly connected to the back of the workbench 1. The drying component 23 includes a drying box 2301 fixed to the back of the workbench 1 and an air pump 2302 for generating airflow. The air pump 2302 is fixedly connected to the inside of the workbench 1 and is connected to the drying box 2301 through an air supply pipe. A plurality of electric heating rods 2303 for heating the airflow are arranged inside the drying box 2301.

[0053] It is understandable that, through the operation of the air pump 2302 and the electric heating rod 2303 , hot air is transported to the vessel 13 through the drying box 2301 , thereby drying the moisture in the vessel 13 .

[0054] In the present invention, the second driving mechanism 7 works, under the cooperation relationship between the gear and the rack, the sleeve rod 5 is driven to slide on the surface of the guide rod 4, so that the tilting rod 801 is separated from the top block 803, and under the action of the elastic plate 804, the tilting rod 801 drives the bottom plate 802 to close the bottom of the sampling cup 6, and the sampling cup 6 is moved to the discharge port position of the sorting equipment for sampling, and then the sampling cup 6 is reset and moved to the top of the vessel 13. When the inclined surface of one end of the tilting rod 801 contacts the top block 803, the top block 803 pushes the tilting rod 801 and the bottom plate 802 to rotate, and the bottom of the sampling cup 6 is opened, so that the sample falls into the vessel 13, and the third The driving mechanism 10 works, and under the meshing relationship between the gear and the gear ring, it drives the mounting block 9 and the container 13 to rotate toward the detector position. In this process, the two thin rods 12 drive the multi-tooth plate 15 to pass over the upper end of the lever 16, so that the two thin rods 12 and the container 13 vibrate, flatten the sample in the container 13, and perform particle size detection on the workbench 1. When the detection is completed, the mounting block 9 drives the container 13 to rotate, and at the same time, the fourth driving mechanism 14 works, and under the meshing relationship between the worm and the worm wheel, it drives the connecting frame 11 and the container 13 to rotate 180 degrees, and pours the sample in the container 13 into the funnel 17 and slides into the collection box 18 for The diamond powder is temporarily stored to avoid wasting. At the same time, the turned vessel 13 is transferred into the cleaning box 19, so that the electric push rod drives the shielding plate 2201 to rise and close the opening to prevent water from splashing during cleaning. At the same time, the shielding plate 2201 drives the scrubbing head 2103 to enter the vessel 13 through the connecting rod 2202, and the water pump 2106 is operated to transport the water in the clean water tank 2105 to the scrubbing head 2103 to flush the vessel 13. Under the action of the blade 2104, the scrubbing head 2103 rotates through the rotary sealing joint 2102 and the bearing, so that the bristles scrub the sample remaining in the vessel 13 to prevent To prevent residual samples from affecting the reuse of the vessel 13, the sewage generated by washing is transported to the sewage tank 20 through a hose for centralized treatment. After washing, the baffle 2201 drives the scrubbing head 2103 to descend, and the mounting block 9 drives the vessel 13 to rotate to the top of the drying box 2301, and hot air is transported to the vessel 13 through the air pump 2302 and the electric heating rod 2303 to dry the moisture in the vessel 13. Then, the mounting block 9 drives the vessel 13 to rotate to the bottom of the sampling cup 6, and the vessel 13 is flipped and reset by the worm and worm gear. Under the action of multiple vessels 13, sampling, testing, scrubbing and drying can be carried out simultaneously to improve work efficiency.
