[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] In industrial production, ensuring the cleanliness of various workpieces and components is an essential task. Industrial cleaning is the process of removing contamination or coatings formed on workpiece surfaces by physical, chemical, or biological processes to restore them to their original condition. Industrial cleaning is a comprehensive technology encompassing the study of scale formation and properties, the selection and formulation of cleaning agents and additives, the use of corrosion inhibitors, cleaning process technology, the development and use of cleaning equipment, cleaning process monitoring techniques, and wastewater treatment.

[0028] Workpiece cleaning has become a quality-critical manufacturing step across all industrial sectors. Cleaning must be performed at the lowest possible cost and in a highly sustainable manner. These conflicting requirements necessitate processes and machines tailored to the specific needs.

[0029] Silicon carbide, a core material for third-generation semiconductors, boasts significant advantages in high-temperature, high-voltage, high-frequency, and high-power semiconductor devices due to its wide bandgap, high thermal conductivity, and high breakdown electric field strength. It is primarily used in new energy vehicles, power electronics, and renewable energy. Removing deposits and buildup from silicon carbide components ensures their stability and durability in semiconductor manufacturing.

[0030] If deposits, metal particles, and organic residues accumulate on SiC components, these contaminants can cause short circuits, disconnection, or performance degradation in semiconductor devices. Furthermore, SiC components are subject to long-term use in high-temperature, high-energy plasma environments, and residual contaminants can cause uneven film coatings. Cleaning SiC components maintains high thermal conductivity and wear resistance, extending component life.

[0031] However, the existing cleaning equipment only has a cleaning function, and does not have a drying function for the workpiece after cleaning, and the drying equipment with a drying function also does not have a cleaning function, so that the functions of each device are relatively simple.

[0032] In order to solve the above problems, Figures 1 to 3 As shown, one embodiment of the present invention provides a cleaning device, comprising a cleaning box 10, a cleaning unit 20, and a drying unit 30. The cleaning box 10 has a cleaning chamber 11 for placing a workpiece. The cleaning unit 20 includes a cleaning pipe 21, the ends of which are connected to a container for holding a cleaning liquid and the cleaning chamber 11, respectively. The drying unit 30 includes a drying element 31, which is disposed within the cleaning box 10.

[0033] By applying the technical solution of the present invention, the workpiece is placed in the cleaning chamber 11 of the cleaning box 10, the cleaning liquid is transported into the cleaning chamber 11 through the cleaning pipe 21, and the workpiece is rinsed with the cleaning liquid. After the workpiece is rinsed, the workpiece is dried using the drying member 31 provided in the cleaning box 10, thereby completing the cleaning and drying operations of the workpiece. Compared with existing cleaning equipment and drying equipment, the integration of cleaning and drying functions is achieved. Moreover, the cleaning and drying of the workpiece can be achieved using only one cleaning box 10. Compared with the solution of placing the workpiece in two different modules for cleaning and drying respectively, the structure of the cleaning device is simplified and the integration of the cleaning device is further improved.

[0034] The cleaning pipe 21 is used to deliver cleaning liquid into the cleaning chamber 11. The cleaning liquid can be delivered to the cleaning chamber 11 using a delivery pump to achieve a certain flow rate, or it can be delivered to the cleaning chamber 11 using a high-low arrangement, utilizing the cleaning liquid's own gravitational potential energy. Regardless of the delivery method, a booster valve or other components can be used to increase the pressure at the outlet of the cleaning pipe 21.

[0035] Generally speaking, the drying unit 31 dries the workpiece by heating.

[0036] like Figure 1 and Figure 2As shown, the cleaning unit also includes a transducer 22 and a plurality of flexible tentacles 23. The transducer 22 can be arranged in the cleaning box 10, and the plurality of flexible tentacles 23 are all arranged on the transducer 22. The plurality of flexible tentacles 23 extend from the transducer 22 to the cleaning chamber 11. The transducer 22 can convert electrical energy into ultrasonic waves. When ultrasonic waves propagate in the cleaning liquid, they can generate tiny bubbles in the liquid through the cavitation effect, and cause the bubbles to burst rapidly, thereby generating vibrations. The impact generated can break up dirt and impurities on the surface of the workpiece. In addition, ultrasonic waves can accelerate chemical reactions in the cleaning liquid and enhance the cleaning liquid's ability to dissolve dirt. At the same time, through the shaking of the flexible tentacles 23, the surface of the workpiece can be cleaned, the dirt on the surface of the workpiece can be quickly removed, and the cleaning liquid and the workpiece can be quickly brought into contact again, thereby improving the cleaning efficiency.

[0037] Among them, transducer 22 is a device that can convert electrical energy into acoustic energy. When the ultrasonic waves generated by transducer 22 propagate in the liquid, acoustic cavitation occurs due to nonlinear effects. The shock wave emitted when the cavitation bubble suddenly closes can generate thousands of atmospheres of pressure around it, directly and repeatedly impacting the dirt. On the one hand, it destroys the adsorption force between the dirt and the workpiece surface, and on the other hand, it also causes the dirt to break off the workpiece surface and disperse into the cleaning liquid. The vibration of the bubbles can also scrub the workpiece surface. The bubbles can also "drill" into cracks and vibrate to dislodge dirt. For greasy dirt, due to ultrasonic cavitation, the two liquids are rapidly dispersed and emulsified at the interface. When the dirt particles are wrapped in oil and adhere to the workpiece surface, the oil is emulsified and the dirt particles fall off.

[0038] The flexible tentacles 23 are made of flexible material. When ultrasonic waves propagate in the cleaning liquid, the flexible tentacles 23 come into flexible contact with the workpiece surface, thereby cleaning dirt detached from the workpiece surface into the cleaning liquid without causing damage to the workpiece surface.

[0039] The transducer 22 can be disposed on the cleaning box 10, meaning that, in some embodiments, the transducer 22 is disposed on the cleaning box 10, allowing the flexible tentacles 23 to extend directly into the cleaning chamber 11. In some embodiments, the transducer 22 is disposed outside the cleaning box 10 and is movable, such that the flexible tentacles 23 can extend into the cleaning box 10 by moving the transducer 22 relative to the cleaning box 10.

[0040] like Figure 2As shown, the cleaning device further includes a rotating rod 40, which is located on one side of the cleaning box 10 and is rotatable about its own axis. The transducer 22 is mounted on the rotating rod 40. The cleaning box 10 has an upper opening that communicates with the cleaning chamber 11. The rotating rod 40 is capable of driving the transducer 22 to flip so that the transducer 22 covers the upper opening. With the above structure, the rotating rod 40 drives the transducer 22 to flip and open the upper opening, preventing the transducer 22 from interfering with the workpiece, thereby facilitating the removal and placement of the workpiece.

[0041] Furthermore, when the workpiece is being cleaned, the upper opening is blocked by the transducer 22 , thereby preventing the splashing of the cleaning liquid and ensuring the internal cleanliness of the cleaning device.

[0042] like Figure 2 As shown, the cleaning unit 20 also includes a pressure regulating pipe 24, the two ends of which are connected to a container for holding a pressurized air source and the cleaning chamber 11. The high-pressure air source can be delivered to the cleaning chamber 11 through the pressure regulating pipe 24, achieving high-pressure flushing of the workpiece to further clean the workpiece.

[0043] In some embodiments, the workpiece is first cleaned using ultrasonic cleaning. Specifically, after the workpiece is placed in the cleaning box 10, the transducer 22 is positioned over the upper opening using the rotating rod 40. Cleaning fluid is then delivered into the cleaning box 10 using the cleaning pipe 21 and brought to a certain height, allowing the flexible tentacles 23 to extend into the cleaning fluid. The transducer 22 is then activated, and the workpiece surface is cleaned using ultrasonic waves and the flexible tentacles 23. After the ultrasonic cleaning is completed, the cleaning fluid is allowed to stand for a period of time, and then the cleaning pipe 21 is used again to continuously and abundantly deliver cleaning fluid into the cleaning box 10. A high-pressure gas source is then delivered to the cleaning box 10 via the pressure regulating pipe 24, pressurizing and flushing the workpiece in the cleaning chamber 11 to further clean the workpiece.

[0044] A liquid level sensor is provided in the cleaning box 10 , and the liquid level sensor can be used to detect the height of the cleaning liquid in the cleaning box 10 , and to control the height of the cleaning liquid during the ultrasonic cleaning process.

[0045] By performing pressurized flushing on the workpiece after ultrasonic cleaning, the problem of low efficiency of traditional ultrasonic cleaning can be solved and the cleaning effect of the workpiece can be improved.

[0046] It should be noted that the cleaning methods of ultrasonic cleaning and high-pressure flushing can be coordinated with each other. In some embodiments, ultrasonic cleaning can be used as the main method, and high-pressure flushing cleaning can be used as a supplementary method. In some embodiments, high-pressure flushing cleaning can be used as the main method, and ultrasonic cleaning can be used as a supplementary method.

[0047] like Figure 8As shown, in some embodiments, the cleaning unit 20 further includes a circulation pump 25 and a filter box 26. The circulation pump 25 is disposed on the cleaning pipe 21. The inlet of the filter box 26 is connected to the outlet of the cleaning box 10. The outlet of the filter box 26 is connected to the first end of the cleaning pipe 21. The second end of the cleaning pipe 21 is connected to the inlet of the cleaning box 10. The circulation pump 25 can circulate the cleaning liquid between the cleaning box 10 and the filter box 26, thereby realizing the recycling of the cleaning liquid, improving the utilization rate of the cleaning liquid, and reducing costs.

[0048] The cleaning liquid after cleaning the workpiece can be filtered through the filter box 26 to remove dirt and impurities in the cleaning liquid so that the cleaning liquid can be reused.

[0049] Furthermore, during the nano-bubble flushing and high-pressure flushing process, the inner wall of the cleaning box 10 can be cleaned, thereby realizing the self-cleaning function of the cleaning box 10 .

[0050] In some embodiments, the cleaning unit 20 further includes a nanobubble generator 27, which is disposed on the cleaning pipe 21 and located between the circulation pump 25 and the cleaning tank 10. The nanobubble generator 27 can form micro-nano bubbles in the cleaning fluid, increasing the number of bubbles in the cleaning chamber 11, thereby further improving the cleaning effect on the workpiece surface after the bubbles burst.

[0051] In some embodiments, the drying unit 31 includes a microwave generator, which is disposed in the cleaning box 10. The microwaves generated by the microwave generator can directly act on the interior of the workpiece to achieve heating. Compared with traditional heating methods such as heat conduction or heat radiation, the workpiece temperature can be increased quickly, with the advantage of low energy consumption.

[0052] The angle of the microwave generator can be adjusted to change the reflection path of the microwave in the cleaning box 10 so that the workpiece is heated more evenly.

[0053] like Figure 2 and Figure 3 As shown, the drying unit 31 further includes a plurality of heating tubes 311, which are spaced apart along the circumference of the cleaning box 10. The drying unit 30 further includes a temperature measuring plate 32. The cleaning box 10 has an upper opening communicating with the cleaning chamber 11, and the temperature measuring plate 32 is openably and closably disposed over the upper opening. The heating tubes 311 can switch operating states based on monitoring data from the temperature measuring plate 32. The temperature of the cleaning chamber 11 can be monitored by the temperature measuring plate 32, and the operating state of the heating tubes 311 can be controlled based on the monitoring data from the temperature measuring plate 32, so that areas with lower temperatures can be heated and the temperature of the cleaning chamber 11 can be made more uniform.

[0054] The temperature measuring plate 32 is also mounted on the rotating rod 40 and is located to one side of the transducer 22. The rotating rod 40 is not only capable of rotating about its own axis but also of moving horizontally. During ultrasonic cleaning, the rotating rod 40 is used to move the transducer 22 horizontally to the side of the cleaning box 10. The rotating rod 40 is then used to rotate the transducer 22 about its own axis, causing the transducer 22 to flip over, thereby allowing the transducer 22 to cover the upper opening. During the drying phase, the rotating rod 40 is used to move the temperature measuring plate 32 horizontally to the side of the cleaning box 10. The rotating rod 40 is then used to rotate the temperature measuring plate 32 about its own axis, causing the temperature measuring plate 32 to flip over, thereby allowing the temperature measuring plate 32 to cover the upper opening.

[0055] Of course, if the temperature inside the cleaning chamber 11 as a whole fails to meet the standard after detection by the temperature measuring plate 32 , all the heating tubes 311 may be activated to accelerate the increase in the temperature of the cleaning chamber 11 .

[0056] After the workpiece cleaning process is completed, the transducer 22 at the upper opening of the cleaning box 10 is first replaced with a temperature measuring plate 32. The microwave generator is activated to heat the workpiece with the microwaves generated by the microwave generator. At the same time, the temperature in the cleaning chamber 11 is monitored. If the temperature in a certain area is too low, the corresponding heating tube 311 is activated to heat the area, raising the temperature of the area and ensuring more uniform heating of the workpiece.

[0057] In some embodiments, microwave heating can be used as a primary method, with heating by the heating tube 311 serving as a secondary method. In some embodiments, heating by the heating tube 311 can be used as a primary method, with heating by microwave heating serving as a secondary method.

[0058] By the microwave drying described above, and by using the temperature measuring plate 32 to monitor the temperature in real time, and by dynamically adjusting the working state of the heating tube 311 , the temperature in the cleaning box 10 is made uniform, and the workpiece is heated uniformly.

[0059] like Figure 3 As shown, the cleaning box 10 includes an inner shell 12, an insulation layer 13, and an outer shell 14, which are arranged in sequence from the inside to the outside. A plurality of heating pipes 311 are arranged between the inner shell 12 and the insulation layer 13. The above-mentioned structure of the cleaning box 10 makes the cleaning box 10 have good thermal insulation performance, so that the workpiece has a good drying effect.

[0060] The outer shell 14 is made of heat-insulating material.

[0061] In some embodiments, the inner wall of the cleaning box 10 is provided with a high-temperature resistant coating. The high-temperature resistant coating can protect the inner wall of the cleaning box 10 from damage due to excessive temperatures. For example, aluminum nitride ceramic coating provides good corrosion resistance and thermal conductivity.

[0062] The high temperature resistant coating is coated on the inner surface of the inner shell 12. The inner shell 12 is made of metal material and can reflect the microwaves generated by the microwave generator to reduce energy consumption.

[0063] It should be noted that the cleaning box 10 is also connected to a vacuum tube. Before the drying process begins, the air in the cleaning box 10 is extracted through the vacuum tube so that the workpiece is dried in a vacuum environment, which can effectively prevent the workpiece from coming into contact with oxygen and avoid the formation of an oxide layer.

[0064] like Figure 2 and Figure 6 As shown, the cleaning device also includes a feed box 50, a discharge box 60 and a transfer arm 70. The feed box 50 is arranged on one side of the cleaning box 10, and the feed box 50 has a plurality of workpiece placement positions 51. The discharge box 60 is arranged on the side of the cleaning box 10 away from the feed box 50, and the discharge box 60 has a plurality of workpiece storage positions 61. The transfer arm 70 is movably arranged above the feed box 50, the cleaning box 10 and the discharge box 60, and the transfer arm 70 has a first position corresponding to the feed box 50, a second position corresponding to the cleaning box 10 and a third position corresponding to the discharge box 60, and the transfer arm 70 can move between the first position, the second position and the third position. With the above arrangement, by placing multiple workpieces at the workpiece placement position 51 of the feed box 50 at the same time, and utilizing the transfer arm 70 to transfer the workpieces one by one to the cleaning box 10, the workpieces can be cleaned and dried one by one, and then the dried workpieces are transferred to the workpiece storage position 61 of the discharge box 60, and then the multiple workpieces can be processed in a predetermined order, which is convenient for realizing the automation of the cleaning device.

[0065] The feed box 50 and the discharge box 60 have the same structure. Each box is equipped with a vertically reciprocating conveyor belt 52, with multiple support plates 53 arranged at intervals on the conveyor belt 52. By providing the conveyor belts 52 on opposite sides, the two opposing support plates 53 form a workpiece placement position 51 and a workpiece storage position 61, thereby enabling the storage of multiple workpieces.

[0066] In some embodiments, a visual detector 85 is positioned above the feed box 50 to detect the position of the workpiece. As the conveyor belt 52 rotates and moves the workpiece, the visual detector 85 detects the workpiece's position relative to the top of the feed box 50. Once the workpiece reaches the top of the feed box 50, the conveyor belt 52 stops, and the workpiece is then transferred via the transfer arm 70. Furthermore, the visual detector 85 observes the workpiece's surface, collects surface contamination data, and automatically matches it to cleaning data in a database, enabling automated operation of the cleaning device.

[0067] like Figure 4 and Figure 5As shown, the transfer arm 70 includes a transfer frame 71, a chain 72, a folding frame 73, and a clamping claw 74. The transfer frame 71 is movably arranged above the cleaning box 10 in the horizontal direction. The transfer frame 71 is provided with a sprocket 76. The chain 72 is rotatably mounted on the sprocket 76. The folding frame 73 is foldably arranged in the vertical direction. The upper end of the folding frame 73 is connected to the chain 72 located on both sides of the sprocket 76. The clamping claw 74 is provided at the lower end of the folding frame 73. Using the above-mentioned transfer arm 70, the transfer frame 71 is moved in the horizontal direction so that it can drive the workpiece to move above the feed box 50, the cleaning box 10, and the discharge box 60. The rotation of the chain 72 can drive the folding frame 73 to fold in the vertical direction, and then drive the workpiece to move in the vertical direction through the clamping claw 74 to transfer within the feed box 50, the cleaning box 10, and the discharge box 60.

[0068] As the sprocket 76 rotates, the chains 72 on either side of the sprocket 76 move toward each other. A fixing block 75 is provided on each chain 72 on either side of the sprocket 76, and the upper end of the folding frame 73 is connected to each of the fixing blocks 75. As the chains 72 rotate with the sprocket 76, the fixing blocks 75 are driven by the chains 72 to move toward and away from each other, thereby extending and folding the folding frame 73. When the folding frame 73 extends, it drives the clamping jaws 74 downward. When the folding frame 73 folds, it drives the clamping jaws 74 upward.

[0069] like Figure 4 and Figure 5 As shown, two sprockets 76 are spaced apart on the transport frame 71, one of which is a driving wheel and the other is a driven wheel. The motor can drive the driving wheel to rotate, and then the driving wheel and the driven wheel simultaneously drive the chain 72 to rotate. For example, when the chain 72 rotates counterclockwise, the chains 72 on both sides of the sprocket 76 move in opposite directions. The chain 72 on the first side of the sprocket 76 moves toward the left side in the figure, and the chain 72 on the second side of the sprocket 76 moves toward the right side in the figure, thereby moving the two fixed blocks 75 away from each other, allowing the folding frame 73 to fold. When the chain 72 rotates clockwise, the folding frame 73 can be stretched.

[0070] In other embodiments, the chain 72 and the sprocket 76 may also be replaced by structures such as a belt and a pulley.

[0071] In some embodiments, the clamping jaw 74 includes a frame 741, a locking block 742, and an electromagnetic control member. The frame 741 is connected to the lower end of the folding frame 73. The locking block 742 is retractably mounted on the frame 741. The frame 741 is provided with a clamping slot 743. The electromagnetic control member can adjust the locking block 742 to a retracted state and an extended state. When the locking block 742 is in the retracted state, it can form an escape opening with the frame 741. The escape opening is connected to the clamping slot 743. When the locking block 742 is in the extended state, the escape opening is closed. With the above-mentioned clamping jaw 74, when the folding frame 73 drives the frame 741 to move downward, the locking block 742 can be pushed back to the retracted state, thereby opening the escape opening and clamping the workpiece using the clamping slot 743. After the workpiece is clamped, the locking block 742 is extended by the electromagnetic control member, thereby closing the escape opening and preventing the workpiece from separating from the clamping jaw 74.

[0072] In some embodiments, a workpiece is placed on a carrier tray 110, which is provided with a handle 111. When the frame 741 moves downward, the locking block 742 contacts the handle 111. Under the restraint of the handle 111, the locking block 742 retracts, and the handle 111 enters the clamping groove 743 through the avoidance opening. The electromagnetic control element then controls the locking block 742 to extend, thereby closing the avoidance opening and allowing the clamping jaw 74 to move the carrier tray 110.
