Description

Technical Field

[0001] The utility model relates to the technical field of diamond particle selection equipment, in particular to automatic constant temperature dehumidification single crystal diamond selection equipment. Background Art

[0002] The selection and grading of single crystal diamonds is a post-processing process for diamonds, which requires the use of selection equipment. By adjusting the tilt angle of the selection disk and setting the vibration frequency of the selection equipment, and using the different friction forces of single crystal diamond particles of different shapes on the selection disk, single crystal diamond particles of equal and non-equal shapes fall into different receiving boxes to achieve the purpose of sorting. Its sorting speed is fast and the time is short, which can improve the production efficiency of single crystal diamond particles.

[0003] In the actual production process, as the humidity of the environment increases, a layer of water vapor will adhere to the surface of the single crystal diamond particles, causing adjacent single crystal diamond particles to stick together. The vibration of the sorting disk alone cannot break them up, and the single crystal diamond particles will even adhere to the sorting disk. The more single crystal diamond particles accumulate on the sorting disk, the greater the impact on the selection results. At present, there are sorting machines on the market that can dry the sorting disk and diamond particles, such as the Chinese utility model patent with the publication number CN204656966U and the patent name "Diamond Sorting Machine Anti-sticking Material Sorting Disk", which discloses that heating devices are set on both sides of the back of the sorting disk body to heat the sorting disk surface and the diamond powder moving on the disk surface to a certain temperature, thereby drying the sorting disk surface and the diamond powder.

[0004] Although the existing diamond selection machine has a certain heating and drying effect on diamonds, it still has the following defects:

[0005] 1. In the past, the heating device of the sorting machine directly heated the sorting plate and used the heat conduction of the sorting plate to heat the diamond. This heat conduction heating method requires the sorting plate to be heated before the diamond can be heated and dried. Its heating efficiency is low and the energy loss is large. Moreover, the heating temperature and heating speed of each part of the sorting plate itself are unstable, which leads to uneven and incomplete heating of the diamonds on the sorting plate and poor heating quality.

[0006] 2. After the existing sorting machine heats and dries the diamond, the water vapor formed after the water on the surface of the diamond evaporates will still spread around the working environment. In the past, the ambient temperature was controlled by air conditioning, and dehumidification was performed using dehumidifiers; if the site is large, the only way to achieve a constant temperature and humidity effect is to increase the number of air conditioners and dehumidifiers, which is costly and the constant temperature and humidity effect is not ideal.

[0037] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0038] like Figure 1-6 As shown, an automatic constant temperature dehumidification single crystal diamond selection device is mainly used for automatic selection and crystal type rating of industrial-grade single crystal artificial diamonds. The automatic constant temperature dehumidification single crystal diamond selection device includes a remote control system, a power module 60, a humidity collection module 53, a constant temperature module 54, a workbench 10, and a feeding mechanism 20, a selection mechanism 30, and a material receiving box 103 arranged on the workbench 10. Among them, the workbench 10 has an operation panel 102 and a frame 101. The operation panel 102 is movably installed on the frame 101, so that one end of the operation panel 102 can be lifted and lowered in the vertical direction. The frame 101 is set on the ground by setting four supporting legs.

[0039] The loading mechanism 20 is provided with a loading hopper 201 , which is mounted on the operation panel 102 of the workbench 10 via a loading bracket 204 , and the loading hopper 201 is arranged above the selection plate 305 , so as to facilitate the loading of the single crystal diamond to be processed in the loading hopper 201 onto the selection mechanism 30 .

[0040] The selection mechanism 30 has a selection disk 305. The selection disk 305 and the receiving box 103 are both installed on the operation panel 102. The receiving box 103 is arranged below the discharge side of the selection disk 305. The selection disk 305 is used to receive the single crystal diamonds put in by the upper hopper 201. The selection disk 305 is arranged above the operation panel 102 of the workbench 10 and has a disk surface that meets the sliding sorting of a certain amount of single crystal diamonds. The discharge side and the blocking side are respectively arranged around the disk surface. After the single crystal diamond falls on the selection disk 305, it will continue to roll, and finally fall from the discharge side of the selection disk 305 and be sorted into the corresponding receiving box 103.

[0041] The upper hopper 201 is roughly configured to be cylindrical, and a high-frequency pulse heater is arranged around the outer periphery of the upper hopper 201. In the embodiment of the present application, the high-frequency pulse heater on the upper hopper 201 preferably uses a high-frequency pulse induction ring 50, and a pulse circuit is arranged inside the high-frequency pulse induction ring 50. The pulse circuit generates high-frequency pulse alternating current, and heat is generated by the electromagnetic induction effect of the high-frequency pulse alternating current to heat and dry the single crystal diamond in the upper hopper 201.

[0042] A plurality of high-frequency pulse induction rings 50 are provided, and the plurality of high-frequency pulse induction rings 50 are set in the vertical direction around the outer periphery of the upper hopper 201, and each high-frequency pulse induction ring 50 surrounds the outer surface of the upper hopper 201, and the high-frequency pulse induction ring 50 does not need to contact the upper hopper 201. Therefore, the heat generated by the high-frequency pulse induction rings 50 heats and dries the single crystal diamond inside the upper hopper 201 in all directions from all sides thereof.

[0043] The constant temperature module 54 is arranged on one side of the loading hopper 201 , and the constant temperature module 54 is fixedly connected to a plurality of high-frequency pulse induction rings 50 , and the constant temperature module 54 is also electrically connected to each high-frequency pulse induction ring 50 , and the constant temperature module 54 and the plurality of high-frequency pulse induction rings 50 are also fixedly mounted on the loading bracket 204 .

[0044] A high-frequency pulse heater is provided at the bottom of the selection disk 305. The high-frequency pulse heater at the bottom of the selection disk 305 preferably uses a high-frequency pulse induction tube 51 in the shape of a strip tube. The high-frequency pulse induction tube 51 is arranged to bend back and forth in the width or length direction of the bottom of the selection disk 305, so that the high-frequency pulse induction tube 51 can be arranged at the bottom of the selection disk 305 in a larger range, and the high-frequency pulse induction tube 51 does not need to contact the selection disk 305. A pulse circuit is provided inside the high-frequency pulse induction tube 51, and the pulse circuit generates high-frequency pulse alternating current. The electromagnetic induction effect of the high-frequency pulse alternating current generates heat to heat and dry the single crystal diamond on the disk surface of the selection disk 305.

[0045] The remote control system can be a computer terminal, and the remote control system includes a main control chip 40, and the main control chip 40 is electrically connected to a power module 60, a humidity collection module 53, a constant temperature module 54, a high-frequency pulse induction ring 50, and a high-frequency induction tube. The constant temperature module 54 is electrically connected to the humidity collection module 53 and the high-frequency pulse heater. The main control chip 40 sends an instruction to start the humidity collection module 53, and the humidity collection module 53 collects the ambient humidity and sends a humidity signal to the main control chip 40.

[0046] The main control chip 40 obtains a humidity signal. If the ambient humidity exceeds 80%, the main control chip 40 sends an instruction to control the constant temperature module 54 to start. The constant temperature module 54 sends an instruction to start the high-frequency pulse induction ring 50 and the high-frequency pulse induction tube 51, which are used to heat and dry the single crystal diamond that needs to be sorted into the receiving box 103. The high-frequency pulse induction ring 50 and the high-frequency pulse induction tube 51 are constantly heated by the constant temperature module 54 during operation, and the constant heating temperature is 100 degrees.

[0047] In this way, the single crystal diamond selection device of the present application is provided with high-frequency pulse heaters around the outer periphery of the upper hopper 201 and the bottom of the selection plate 305, so that the heat generated by the high-frequency magnetic field of the high-frequency pulse heater is used to heat and dry the single crystal diamonds on the upper hopper 201 and the selection plate 305. Compared with the previous method of directly heating and drying diamonds by heating the selection plate 305, the heat heating range of the electromagnetic induction effect is wide and the heating speed is fast, so that all single crystal diamonds can be evenly and efficiently heated and dried, and there is no need to heat the upper hopper 201 and the selection plate 305, thereby reducing energy loss.

[0048] In addition, a humidity acquisition module 53 is provided to collect humidity data of the working environment. When the humidity feedback from the humidity acquisition module 53 is greater than 80%, a humidity signal is fed back to the main control chip 40, so that the main control chip 40 sends instructions to control the constant temperature module 54 to drive the high-frequency pulse heater, and the constant temperature module 54 keeps the heating temperature constant at about 100 degrees, thereby achieving the purpose of automatic constant temperature dehumidification of single crystal diamond.

[0049] The inner wall of the upper hopper 201 is provided with a spiral trough 205, which is formed by welding a trough on the inner wall of the upper hopper 201, and the spiral trough 205 spirally extends from the feed port of the upper hopper 201 to the discharge port of the upper hopper 201, so that the single crystal diamond is spirally dropped into the upper hopper 201.

[0050] In this way, by providing a spirally arranged spiral trough 205 on the inner wall of the upper hopper 201, the single crystal diamond slides from the feed port of the upper hopper 201 along the spiral trough 205 to the discharge port. The single crystal diamond can be completely spread out during the sliding process on the spiral trough 205, which can avoid the problem of air blockage caused by the stacking of single crystal diamonds in the upper hopper 201. Combined with the heating function of the high-frequency pulse induction ring 50, the heating and drying efficiency and quality of the single crystal diamond are further improved.

[0051] In the embodiment of the present application, a water vapor collector 52 is arranged above the selection disk 305, and the water vapor collector 52 is electrically connected to the power module 60 and the main control chip 40. When the single crystal diamond is heated and dried, the main control chip 40 obtains electric energy and drives the water vapor collector 52 to collect the water vapor generated when the single crystal diamond is heated on the upper hopper 201 and the selection disk 305. Thereby, the purpose of quickly collecting the water vapor when it rises is achieved, and it is avoided that it spreads to the surrounding of the working environment and affects the heating and drying effect of the single crystal diamond. Compared with the previous implementation method of using air conditioners and dehumidifiers for dehumidification and dehumidification, the arrangement of the water vapor collector 52 will obviously save more costs, and it can collect the rising water vapor in time, and the constant humidity effect is better.

[0052] The selection device also includes an input module 64 and a feeding vibrator 202 and a selection vibrator 301 electrically connected to the input module 64. The feeding vibrator 202 and the selection vibrator 301 are electrically connected to the main control chip 40 through the input module 64. The feeding vibrator 202 and the selection vibrator 301 are preferably vibration motors. The input module 64 has a display screen and operation buttons. The user can intuitively view the currently set selection parameters through the display screen set on the input module 64. This facilitates the user to control the crystal grade of the single crystal diamond in real time, ensures the selection result of the single crystal diamond, and makes the product crystal quality more stable. By setting the operation buttons, it is convenient for the user to manually input the selection parameters and save them.

[0053] The feeding vibrator 202 is arranged on the upper hopper 201 , the upper hopper 201 is connected with a feeding trough 203 and single crystal diamond is fed to the selection disk 305 through the feeding trough 203 , and the feeding trough 203 is arranged below the upper hopper 201 and above the selection disk 305 .

[0054] Since the feeding vibrator 202 is connected to the input module 64, the feeding vibrator 202 sets the vibration frequency according to the selection parameters preset in the input module 64, and the selection parameters include the vibration frequencies of the feeding trough 203 and the upper hopper 201. Therefore, the upper hopper 201 and the feeding trough 203 are vibrated by the feeding vibrator 202, so that the single crystal diamonds to be sorted in the upper hopper 201 fall into the feeding trough 203 and the selection plate 305 in sequence, so as to achieve the purpose of automatic feeding of single crystal diamonds, save labor costs, avoid human error operations, and improve the selection and grading efficiency and quality of single crystal diamonds.

[0055] The selection vibrator 301 is installed on the selection disk 305. The selection vibrator 301 adjusts the vibration frequency of the selection disk 305 according to the selection parameters preset by the input module 64, so that the selection vibrator 301 transmits vibration force to the selection disk 305 according to the set vibration frequency, so as to ensure that the single crystal diamond on the selection disk 305 can slide smoothly on the inclined surface of the selection disk 305 at the vibration frequency.

[0056] Moreover, the high-frequency pulse induction tube 51 is arranged at the bottom of the selection disk 305 in a reciprocating manner, and the high-frequency pulse induction tube 51 is fixedly connected to the selection vibrator 301, so that the high-frequency pulse induction tube 51 can stably heat and dry the single crystal diamond on the selection disk 305.

[0057] In the embodiment of the present application, the selection device includes a tilt adjuster 1 302 , a tilt adjuster 2 303 and an angle detection module 304 . The tilt adjuster 1 302 , the tilt adjuster 2 303 and the angle detection module 304 are all electrically connected to the input module 64 .

[0058] The workbench 10 has a frame 101 and an operation panel 102 installed on the frame 101, wherein a tilt adjuster 302 is arranged on the operation panel 102, and an adjustment rod is connected to the output end of the tilt adjuster 302, and the adjustment rod is connected to the bottom of the discharge side of the selection disk 305. The tilt adjuster 1 is used to control the vertical lifting of the adjustment rod, thereby achieving the purpose of controlling the angle between the discharge side of the selection disk 305 and the horizontal plane, that is, the tilt angle between the discharge side of the selection disk 305 and the horizontal direction is adjusted by the tilt adjuster 302 according to the selection parameters input by the input module 64.

[0059] The second inclinometer 303 is arranged on the frame 101 of the workbench 10 and below the operation panel 102. The output end of the second inclinometer 303 is connected to the adjustment rod, and the adjustment rod is connected to the material stopper side of the selection plate 305. Specifically, since one end of the operation panel 102 is supported on the frame 101, and the other end of the operation panel 102 is supported on the adjustment rod, the lower end of the adjustment rod is connected and movably installed on the frame 101 through the second inclinometer 303, so that the second inclinometer 303 is connected to the bottom of the operation panel 102 through the adjustment rod.

[0060] Since the selection disk 305 and the material receiving box 103 are both installed on the operation panel 102, the vertical lifting and lowering of the adjustment rod is controlled by the inclinometer 2 303 to achieve the purpose of controlling the angle between the material blocking side of the selection disk 305 and the horizontal plane, that is, the inclinometer 2 303 is used to adjust the inclination angle between the material blocking side of the selection disk 305 and the horizontal direction according to the selection parameters input by the input module 64.

[0061] Before using the sorting equipment to sort single crystal diamonds, preset selection parameters are input in advance through the input module 64, so that the tilt adjuster 1 302 and the tilt adjuster 2 303 adjust the front tilt angle and the rear tilt angle of the selection disk 305 according to the preset parameters, that is, adjust the selection angle value of the selection disk 305 to ensure that the single crystal diamond can smoothly slide onto the corresponding receiving box 103 on the inclined surface of the selection disk 305 with the inclined angle set.

[0062] The angle detection module 304 of the present application is connected to the input module 64, so that the angle detection module 304 detects the vibration frequency and the tilt angle of the selection disk 305 in real time, and the angle detection module 304 feeds back the detection signal of the vibration frequency and the tilt angle of the selection disk 305 to the input module 64. Under the control of the main control chip 40, the input module 64 can adjust and calibrate the selection parameters of the selection disk 305 according to the signal fed back by the angle detection module 304, so as to achieve the purpose of real-time monitoring and calibration of the selection disk 305 for sorting single crystal diamonds, and improve the sorting accuracy of the selection disk 305.

[0063] The first inclinometer 302 and the second inclinometer 303 used in the present application preferably use adjustment motors, and the angle detection module 304 preferably uses a gyroscope.

[0064] The selection device also includes a position acquisition module 61, and an image analysis module 41 and a database 42 of the remote control system. The position acquisition module 61 obtains the crystal grade information of the corresponding single crystal diamond falling into the corresponding receiving box 103 based on the position information of the single crystal diamond on the selection disk 305. The crystal grade information of the single crystal diamond at least includes a photo of the single crystal diamond falling into the box, a photo of the same material box and a discrete diagram.

[0065] More specifically, the position acquisition module 61 includes a positioning module 62 and a camera module 63 , both of which are electrically connected to the main control chip 40 , and the positioning module 62 and the camera module 63 are correspondingly arranged on each of the receiving boxes 103 .

[0066] Since a plurality of position acquisition modules 61 are arranged on the acquisition bracket of the rack 101, the position acquisition modules 61 are installed on the operation panel 102 of the workbench 10 through the acquisition bracket, and each receiving box 103 is provided with a corresponding position acquisition module 61 (including a positioning module 62 and a camera module 63).

[0067] The positioning module 62 of the present application preferably uses an infrared displacement sensor, the camera module 63 preferably uses a high-speed motion camera, and the camera module 63 has an automatic fill light source. The model of the camera module 63 can be NPX-GS6500UM; because the single crystal diamond has a certain flow speed on the selection disk 305, the shooting frequency of the camera module 63 is set at 100 frames-1000 frames per second.

[0068] The position information of the single crystal diamond on the selection disk 305 is obtained by the positioning module 62, and the camera module 63 receives the position information of the single crystal diamond transmitted by the positioning module 62 of the same group. Under the guidance of the position information, the camera module 63 takes a picture of the corresponding single crystal diamond falling into the receiving box 103 according to the position information, and records which receiving box 103 the single crystal diamond falls into, thereby achieving the purpose of automatic tracking and recording of the single crystal diamond falling into the receiving box 103.

[0069] The camera module 63 transmits the collected box-dropping photos to the main control chip 40 . The main control chip 40 receives the box-dropping photos and integrates and arranges the box-dropping photos of all single crystal diamonds in the same receiving box 103 to obtain the same box-dropping photos, and marks the receiving box 103 to which it belongs.

[0070] The image analysis module 41 is connected to the main control chip 40, and the image analysis module 41 receives the photo of the same material box sent by the main control chip 40; then, the image analysis module 41 analyzes the photo of the same material box of each receiving box 103, obtains the relevant information of the transmittance and roundness of the single crystal diamond in the photo of the same material box, and makes a discrete graph of transmittance-roundness for horizontal comparison based on the transmittance and roundness of the single crystal diamond.

[0071] Of course, the analysis of single crystal diamond by the image analysis module 41 is not limited to transmittance and roundness, but also includes related information such as the number of edges, outer contour, compactness, ellipticity, roughness, minimum particle size, equal circle diameter, etc. of the single crystal diamond particles.

[0072] The image analysis module 41 compares and analyzes the discrete graph, and makes a merging suggestion based on the single crystal diamonds with similar parameters in the material receiving box 103, that is, the crystal grade information, and makes a corresponding crystal grade mark. The image analysis module 41 feeds back the crystal grade information to the main control chip 40. The database 42 of the present application has standard crystal grade information stored by photo records.
