[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] An embodiment of the present utility model provides a diamond ultrasonic dispersion cleaning device 100 .

[0039] See also Figure 1 and Figure 2 In one embodiment of the present invention, the diamond ultrasonic dispersion cleaning device 100 includes a metal tank 110, an ultrasonic device 120, a stirring device 130 and a heating device 140;

[0040] The metal tank body 110 is used to contain the diamond powder mixture. The metal tank body 110 has a discharge port 111 at the bottom and a feed port 112 away from the discharge port 111.

[0041] The ultrasonic device 120 is provided in the metal tank body 110 and is used to provide ultrasonic cleaning for the diamond powder mixture in the metal tank body 110;

[0042] The stirring device 130 is disposed inside the metal can body 110 and is used to disperse the diamond powder mixture in the metal can body 110;

[0043] The heating device 140 is used to heat the diamond micropowder mixture in the metal can body 110 to accelerate the cleaning and dissolution of impurities in the diamond micropowder mixture.

[0044] It is understood that the present invention's technical solution achieves the cleaning of impurities attached to diamond powder by providing a metal tank 110, an ultrasonic device 120, a stirring device 130, and a heating device 140. Specifically, the metal tank 110 is used to contain a diamond powder mixture, the ultrasonic device 120 is used to provide ultrasonic cleaning for the diamond powder mixture within the metal tank 110, the stirring device 130 is used to disperse the diamond powder mixture within the metal tank 110, and the heating device 140 is used to accelerate the cleaning and dissolution of impurities within the diamond powder mixture.

[0045] It should also be noted that the diamond ultrasonic dispersion cleaning device 100 is mainly used to assist in opening the soft agglomeration of the diamond material, and on the other hand, it can also dissolve some water-soluble chemical impurities in the cleaning solution. The diamonds processed by the prior art often do not require too precise micropowder particles, and in order to have a good suspension effect or reduce the surface tension between the micropowder particles when the diamond is used as a polishing liquid, some chemical adjuvants such as surfactants, sodium silicate, dispersants, sedimentation agents, etc. are usually added to the diamond micropowder. However, when such micropowder particles are used in the semiconductor field, they often cause scratches on the ground parts due to the presence of oversized particles in the existing diamond micropowder particles. However, when the diamond micropowder is oversized, electroforming screen screening is usually adopted. Therefore, in order to avoid the influence of metal ions on the surface of the diamond micropowder on the oversized screening of the diamond micropowder, the surface impurities of the diamond micropowder of the prior art need to be cleaned.

[0046] It should also be noted that the cleaning liquid added to the metal can body 110 can be water, deionized water or acidic cleaning liquid. Generally, the surface impurities of diamond powder are some water-soluble chemical substances.

[0047] It should also be noted that the heating device 140 is used to accelerate the cleaning and dissolution of impurities in the diamond micropowder mixture, which mainly means that the heating device 140 can increase the temperature of the diamond micropowder mixture, increase the molecular movement speed and solubility in the solution, and thus accelerate the dissolution of soluble substances.

[0048] Optionally, the heating device 140 may be a water bath heater, a microwave heater, a resistance rod heater, or the like.

[0049] See also Figure 2 In a specific embodiment of the present invention, an outer shell 113 is further provided on the outside of the metal can body 110, and an accommodating cavity 112a is formed between the outside of the metal can body 110 and the outer shell 113;

[0050] The heating device 140 is an oil temperature machine; the output end 142 of the oil temperature machine for outputting the heat-conducting medium and the input end 141 for returning the heat-conducting medium are respectively connected to the accommodating cavity 112a, and the accommodating cavity 112a is used to accommodate the heat-conducting medium so that the heat-conducting medium heats the diamond micropowder mixture through the metal tank body 110.

[0051] It's understood that oil temperature controllers use thermal oil as a heat transfer medium. Specifically, thermal oil has high thermal conductivity, allowing it to quickly transfer heat to the target device, improving heating efficiency. Oil temperature controllers are also typically equipped with advanced temperature control systems, enabling precise temperature control with minimal temperature fluctuations, helping to ensure stable heating temperatures and the quality of the resulting cleaned product.

[0052] See also Figure 2 and Figure 4 In a specific embodiment of the present invention, the diamond ultrasonic dispersion cleaning device 100 further includes a spray head 150 , which is disposed inside the metal tank body 110 and close to the top of the metal tank body 110 .

[0053] Specifically, the spray head 150 has a plurality of liquid spraying ports 151 , and the plurality of liquid spraying ports 151 can clean the inner wall of the metal can body 110 .

[0054] It is understood that the spray head 150 can be provided to add cleaning liquid into the metal can body 110. When the spray head 150 has multiple liquid spraying ports 151, the spraying range of the spray head 150 becomes larger, thereby facilitating the flushing of the diamond powder attached to the inner surface of the metal can body 110.

[0055] See also Figure 1 、 Figure 2 and Figure 3 In one embodiment of the present invention, the diamond ultrasonic dispersion cleaning equipment 100 further includes a visual device 160, which includes a transparent cover 161 and a connecting structure 162. The connecting structure 162 is connected to the interior of the metal can body 110, and the transparent cover 161 can be detached from the connecting structure 162.

[0056] It is understood that the provision of the transparent cover 161 facilitates the operator to observe the internal working conditions of the metal tank 110, such as the volume of the diamond powder mixture in the metal tank 110. It is also understood that after the transparent cover 161 can be separated from the connecting structure 162, the connecting structure 162 can also form a manhole, thereby facilitating the addition of other auxiliary agents into the metal tank 110.

[0057] Specifically, if Figure 2 As shown, the transparent cover 161 and the connecting structure 162 are flipped and connected, and the transparent cover 161 and the connecting structure 162 are fixedly connected by screws.

[0058] See also Figure 1 and Figure 2 In a specific embodiment of the present invention, the stirring device 130 includes a driving motor 131 and a stirring rod 132 . The driving motor 131 is used to drive the stirring rod 132 to rotate. A stirring blade 133 is provided at one end of the stirring rod 132 away from the driving motor 131 .

[0059] It can be understood that a stirring blade 133 is provided at the end of the stirring rod 132 away from the drive motor 131, rather than arranging multiple stirring blades 133 in parallel on the entire stirring rod 132. Therefore, the above feature helps to reduce the load of the drive motor 131 and reduce the operating noise of the equipment.

[0060] It should also be noted that the diamond ultrasonic dispersion cleaning device 100 primarily utilizes the ultrasonic device 120 for cleaning, and the stirring device 130 primarily performs the function of stirring and dispersing. Therefore, the stirring blade 133 is only provided at the end of the stirring rod 132 away from the drive motor 131 to achieve the desired stirring and dispersing function.

[0061] Optionally, in order to improve the dispersion effect, the surface of the stirring blade 133 has a notch 1331 .

[0062] See also Figure 2 、 Figure 3 and Figure 4 In a specific embodiment of the present invention, the ultrasonic device 120 is an ultrasonic rod 121, which is located inside the metal tank 110 and contains the diamond powder mixture. It is understood that in the above-described technical solution, the stirring blade 133 is positioned to avoid the ultrasonic rod 121, thereby providing space for the ultrasonic rod 121 to be accommodated within the metal tank 110. Furthermore, the placement of the ultrasonic rod 121 inside the metal tank 110 prevents the ultrasonic device 120 from occupying external space.

[0063] Optionally, see Figure 2 The ultrasonic device 120 has an ultrasonic vibrator 122, which is disposed outside the metal can body 110 and connected to the metal can body 110. It is understood that the ultrasonic vibrator 122 provides ultrasonic waves with higher power than the ultrasonic rod 121, and has a better cleaning effect.

[0064] It should also be noted that, in any of the above embodiments, the inner wall of the metal can body 110 is coated with a corrosion-resistant coating; the corrosion-resistant coating is a Teflon coating.

[0065] It is understood that the main material of the Teflon coating is polytetrafluoroethylene (PTFE). Teflon has strong chemical corrosion resistance. The surface of the Teflon coating is smooth, not easy to adhere to substances, and easy to clean and maintain.

[0066] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
