[0002] In existing crystalline silicon solar cell manufacturing technologies, processes such as coating require high vacuum conditions to improve film quality and uniformity. Pneumatic vacuum damper valves, driven by pneumatic actuators, open and close to cut off or connect airflow. Over extended production, deposits or unreacted residues generated during the process accumulate on the pneumatic vacuum damper valves. These deposits affect vacuum leakage and valve opening / closing performance, leading to unstable vacuum pressure and consequently impacting film quality and production efficiency.

[0003] Currently, cleaning pneumatic vacuum baffle valves mainly relies on manual operation. However, some processes generate hard deposits, making manual cleaning time-consuming, labor-intensive, and extremely inefficient. Moreover, due to differences in the strength of different personnel, the cleaning process can easily damage the pneumatic vacuum baffle valves, such as deforming the sealing surface and bellows, leading to valve failure. This not only increases the maintenance cost of vacuum baffle valves but also affects the continuity and stability of production. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] In existing crystalline silicon solar cell manufacturing technologies, processes such as coating require high vacuum conditions. This reduces gas molecule interference, avoids oxidation and contamination, increases the mean free path of particles, rapidly stabilizes the evaporation rate, and optimizes the condensation and crystallization processes, thereby improving the quality and uniformity of the film. Pneumatic vacuum damper valves, as an important component of the vacuum system, are driven by pneumatic actuators to open and close, cutting off or connecting the airflow and playing a crucial role in ensuring the stable operation of the vacuum system.

[0025] However, with prolonged production operation, deposits or unreacted residues generated during the process can accumulate and adhere to the sealing surfaces and bellows of the pneumatic vacuum baffle valve as the gas flows. These deposits can affect the vacuum leakage rate and the valve's opening and closing performance, leading to unstable vacuum pressure and consequently impacting membrane quality and production efficiency. Therefore, maintenance personnel need to clean the pneumatic vacuum baffle valve regularly.

[0026] Currently, cleaning pneumatic vacuum baffle valves mainly relies on manual operation. However, manual cleaning has many problems: on the one hand, some processes produce hard deposits, making manual cleaning time-consuming, labor-intensive, and extremely inefficient; on the other hand, due to differences in the strength of different personnel, the pneumatic vacuum baffle valve is easily damaged during cleaning, such as deformation of the sealing surface and bellows, leading to valve failure. This not only increases equipment maintenance costs but also affects the continuity and stability of production.

[0027] Based on this, this application discloses a cleaning device that can achieve automated cleaning of valves or tanks, avoid damage and deformation caused by manual cleaning, extend the service life of valves, reduce maintenance workload, reduce costs, and improve production efficiency.

[0028] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0029] Please see Figures 1 to 5 , Figure 1 This is one of the structural schematic diagrams of the cleaning device provided in the embodiments of this application. Figure 2 This is the second schematic diagram of the cleaning device provided in the embodiments of this application. Figure 3 This is the third schematic diagram of the cleaning device provided in the embodiments of this application. Figure 4 This is a schematic diagram of the valve structure provided in an embodiment of this application. Figure 5 This is a schematic diagram of the tank structure provided in an embodiment of this application. This application discloses a cleaning device 100 for cleaning a component 200 to be cleaned, which is a valve 201 or a tank 202. The cleaning device 100 includes: a base 1; a first cleaning box 2, disposed on the base 1, the first cleaning box 2 having a first receiving cavity, the top of the first receiving cavity having a first opening, and the first receiving cavity being used to hold cleaning fluid so that the component 200 to be cleaned is immersed in the cleaning fluid within the first receiving cavity; and a second cleaning box 3, disposed on the base 1, the second cleaning box 3 having a second receiving cavity. The cavity has a second opening on its side, and there is a gap between the second opening and the bottom wall of the second cavity; a clamping mechanism 4 is disposed on the base 1, and the clamping mechanism 4 is used to clamp the part to be cleaned 200. The clamping mechanism 4 is configured to extend into or out of the second cavity through the opening to drive the soaked part to be cleaned 200 into or out of the second cavity; a cleaning mechanism 5 is disposed on the base 1 and located in the second cavity. The cleaning mechanism 5 is configured to spray a cleaning medium onto the soaked part to be cleaned 200 to clean the soaked part to be cleaned 200.

[0030] The base 1 provides a unified mounting reference surface for other components of the cleaning device 100, which facilitates the assembly and debugging of the entire cleaning device 100. The base 1 can absorb and disperse the vibration generated during the cleaning process, extend the service life of the cleaning device 100, and reduce problems such as loosening or damage of parts caused by vibration or shaking.

[0031] The first receiving cavity is used to hold the cleaning solution. The part to be cleaned 200 is immersed in the cleaning solution, which makes full use of the immersion method for cleaning. Since most of the reactive deposits generated in processes such as coating are hygroscopic, immersion can soften the deposits, making them easier to clean in subsequent processes. For some parts with complex structures or those that are difficult to directly contact with the cleaning medium, immersion can penetrate into every corner, gradually softening and removing the dirt, thus improving the thoroughness of the cleaning.

[0032] The top of the first receiving cavity is provided with a first opening to facilitate the insertion and removal of the part to be cleaned 200. During the soaking process, no additional mechanical stirring or shaking is required to effectively remove dirt from the surface of the part to be cleaned 200, reducing the risk of surface scratches that may be caused by mechanical cleaning, and also reducing energy consumption during the cleaning process.

[0033] The second receiving cavity cleaning mechanism 5 provides an installation position and also provides cleaning space for the subsequent cleaning process. The second cleaning box 3 can prevent problems such as splashing of cleaning liquid and dust generated when the cleaning mechanism 5 sprays the parts to be cleaned 200, thus ensuring the cleanliness of the cleaning environment.

[0034] Furthermore, the second opening allows the clamping mechanism 4 to pass through, facilitating the entry and exit of the part to be cleaned 200. The distance between the second opening and the bottom wall ensures that wastewater and dirt generated during the cleaning process will not flow out from the second opening, preventing dirt from contaminating the clamping mechanism 4 and affecting the subsequent cleaning effect. The second opening also facilitates air circulation, preventing the generation of excessive bubbles or water mist during the cleaning process, which could affect the normal progress of the cleaning operation.

[0035] The clamping mechanism 4 enables the part to be cleaned 200 to be automatically transferred at different cleaning stages, reducing the workload of frequent manual handling of the part to be cleaned 200, and lowering the labor intensity and error rate of manual operation. During the transfer process, the clamping mechanism 4 can precisely control the position and orientation of the part to be cleaned 200, ensuring that the part to be cleaned 200 maintains the best stress state and contact mode at all times during the cleaning process, thereby improving the cleaning effect.

[0036] By extending into or exiting the second receiving cavity through the second opening, the clamping mechanism 4 can quickly position and fix the part to be cleaned 200, saving switching time during the cleaning process and improving the overall working efficiency of the cleaning device 100. Furthermore, the stability of the clamping mechanism 4 ensures that the part to be cleaned 200 is not damaged during movement, preventing it from falling or colliding with other components due to unstable clamping, thus avoiding malfunction of the cleaning device 100 or scrapping of the part to be cleaned 200.

[0037] The cleaning mechanism 5 is located within the second receiving cavity, enabling close-range spray cleaning of the immersed part 200. This maximizes the use of the cleaning medium's energy, increasing cleaning pressure and impact force to effectively remove softened dirt particles. The combination of spraying and immersion cleaning by the cleaning mechanism 5 forms a complete cleaning process, achieving a higher level of cleanliness on the surface of the part 200.

[0038] Optionally, the cleaning mechanism 5 can be adjusted according to different cleaning needs, such as the nozzle angle, spray pressure, and flow rate, to adapt to various types of parts 200 to be cleaned and the level of dirt. This flexibility makes the cleaning device 100 widely applicable, and suitable combinations of cleaning parameters can be found for valves 201 and tanks 202 of different materials and shapes to achieve efficient cleaning results.

[0039] It is understood that the cleaning medium is a fluid medium, which can be water, cleaning solution, or cleaning gas, etc. When selecting the cleaning medium, the material of the part 200 to be cleaned, the type of dirt, and the compatibility of the cleaning device can be considered to ensure that the cleaning work is completed safely and efficiently.

[0040] Thus, the cleaning device 100 provided in this embodiment first softens the dirt by soaking the part to be cleaned 200 in the cleaning solution in the first cleaning tank 2, and then uses the cleaning mechanism 5 to spray clean it, which improves the cleaning efficiency and cleanliness, and can quickly remove various stubborn dirt from the surface of the valve 201 or tank 202. The entire cleaning process is mainly completed by the clamping mechanism 4 and the cleaning mechanism 5, which reduces the number of manual operation steps and workload, reduces labor costs, and avoids scratches, bumps and other damage to the surface of the valve 201 or tank 202 that may be caused by improper human operation. It can better protect the surface quality and structural integrity of the part to be cleaned 200, and also avoids the problem of unstable cleaning quality caused by human factors, thus improving the continuity and stability of production.

[0041] Please see Figure 1 and Figure 3In some embodiments, the cleaning device 100 includes: a drain line 6, one end of which is connected to an external liquid supply device, and the other end of which is connected to at least one of a first receiving cavity and a second receiving cavity; and a suction member 7, which is disposed in the drain line 6 and configured to draw cleaning fluid from at least one of the first receiving cavity and the second receiving cavity into the drain line 6.

[0042] One end of the drain pipe 6 is connected to an external liquid supply device, and the other end is connected to at least one of the first and second receiving chambers, forming a complete cleaning fluid path. In actual cleaning operations, after the cleaning fluid soaks and cleans the parts to be cleaned 200 in the receiving chamber, it often contains a large amount of dirt. Direct discharge would result in resource waste and environmental pollution. The existence of the drain pipe 6 allows this dirt-containing cleaning fluid to be extracted and transported to the external liquid supply device for centralized treatment, such as filtration, sedimentation, and purification. The treated cleaning fluid can then be returned to the receiving chamber for cleaning, reducing the amount of cleaning fluid used and lowering production costs.

[0043] Furthermore, the liquid extraction component 7 provides power support for the circulation of the cleaning fluid. Installed in the drain pipe 6, the liquid extraction component 7 can actively draw the cleaning fluid from the receiving cavity to the drain pipe 6. During the operation of the cleaning device 100, the speed and amount of liquid extracted can be flexibly controlled according to actual needs.

[0044] The combination of the drain pipe 6 and the suction unit 7 not only optimizes the cleaning fluid management capability of the cleaning device, but also enhances the controllability and automation of the cleaning process. This allows the entire cleaning device 100 to more flexibly adjust the cleaning fluid usage strategy when cleaning different types of parts 200 to be cleaned, providing an efficient cleaning solution for both complex parts that require frequent cleaning fluid changes and stubborn dirt parts that have been soaked for a long time.

[0045] Please see Figure 1 and Figure 3 In some embodiments, the cleaning device 100 further includes: an inlet pipe 8, which is connected to the inside of the first receiving cavity and is used to connect to an external liquid supply device; an inlet valve 81, which is disposed in the inlet pipe 8 and is used to control the opening and closing state of the inlet pipe 8; an outlet valve 61, which is disposed in the outlet pipe 6 and is used to control the opening and closing state of the outlet pipe 6; a liquid level sensor, which is disposed in the first receiving cavity; and a control unit, wherein the inlet valve 81, the outlet valve 61, and the liquid level sensor are all electrically connected to the control unit, the liquid level sensor is used to detect the liquid level height of the cleaning liquid in the first receiving cavity, and the control unit is used to control the opening and closing state of the inlet valve 81 and the outlet valve 61 according to the liquid level height.

[0046] The liquid inlet pipe 8 is connected to the inside of the first receiving cavity and to an external liquid supply device, providing a stable delivery channel for replenishing the cleaning fluid. This allows the cleaning fluid to be added to the first receiving cavity in a timely and accurate manner according to actual needs during the cleaning process, ensuring sufficient liquid volume and appropriate liquid level during the immersion cleaning stage. This, in turn, ensures that the cleaning fluid fully immerses and penetrates the workpiece 200 to be cleaned, improving the effectiveness of chemical cleaning.

[0047] The inlet valve 81 is installed in the inlet pipe 8 and is used to control the opening and closing state of the inlet pipe 8. The outlet valve 61 is installed in the outlet pipe 6 and works in conjunction with the inlet valve 81 to manage the inflow and outflow of the cleaning fluid.

[0048] Under the command of the control unit, the inlet valve 81 can control the timing and flow rate of the cleaning fluid. For example, when the cleaning fluid level is lower than the preset value, the inlet valve 81 automatically opens to replenish the cleaning fluid to the appropriate level; and when the required level is reached, it can be closed in time to avoid excessive addition and waste of cleaning fluid, while preventing the risk of overflow due to excessive liquid level, thus ensuring the stable operation of the cleaning device.

[0049] Under the control of the control unit, the outlet valve 61 controls the opening and closing of the drain pipe 6, determining when the cleaning solution is drawn out and discharged. When the cleaning solution has completed its soaking task and contains a large amount of dirt requiring replacement, the outlet valve 61 opens, allowing the old cleaning solution to be discharged through the drain pipe 6, making room for the injection of new cleaning solution. This achieves orderly replacement of the cleaning solution and improves the cleaning quality.

[0050] A level sensor is installed in the first receiving chamber to monitor the level of the cleaning fluid and feeds the data back to the control unit. The control unit then determines when to add or remove the cleaning fluid based on the data, thereby controlling the opening and closing of the inlet valve 81 and the outlet valve 61. This automated and precise level control method reduces manual intervention, lowers the risk of abnormal levels due to human error, and improves the overall operating efficiency of the cleaning device.

[0051] Please see Figure 1 and Figure 3 In some embodiments, the first cleaning box 2 and the second cleaning box 3 are arranged along a first horizontal direction, and the first cleaning box 2 and the second cleaning box 3 are arranged adjacent to each other.

[0052] The first cleaning tank 2 and the second cleaning tank 3 are arranged along the first horizontal direction, making the entire cleaning device 100 more compact and rational in terms of spatial layout. The first cleaning tank 2 and the second cleaning tank 3 are arranged adjacently, which effectively utilizes space and avoids problems such as space waste and redundant pipelines caused by excessive spacing between the first cleaning tank 2 and the second cleaning tank 3. The adjacent arrangement makes the pipeline connection simpler and more efficient, reduces the resistance and energy loss of the cleaning fluid during transportation, and improves the operating efficiency of the cleaning device 100.

[0053] Furthermore, the first cleaning box 2 and the second cleaning box 3 are arranged adjacent to each other, facilitating the rapid transfer of the part to be cleaned 200 between the two cleaning stages. After the part to be cleaned 200 has been soaked and softened by dirt in the first cleaning box 2, it can be quickly transferred by the clamping mechanism 4 to the second cleaning box 3 for further spray cleaning, eliminating the need for long-distance handling and complex positioning adjustments, shortening the cleaning cycle and improving production efficiency.

[0054] Please see Figure 2 In some embodiments, the cleaning mechanism 5 includes a spray assembly 51, which is disposed on the base 1 and located inside the second cleaning tank 3. The spray assembly 51 is connected to an external liquid supply device to spray cleaning liquid onto the soaked workpiece 200.

[0055] The spray assembly 51 is mounted on the base 1 and located inside the second cleaning tank 3, and is connected to an external liquid supply device. It sprays cleaning fluid onto the soaked part 200, allowing the cleaning fluid to act on the surface of the part 200 in a high-pressure, directional manner. Especially for valves 201 or tanks 202 with complex shapes and many gaps, the spray assembly 51 can reach these hard-to-reach areas, thoroughly rinsing away the softened dirt after soaking. Compared to simple soaking cleaning, spray cleaning provides stronger mechanical impact, effectively removing stubborn dirt and improving cleaning cleanliness and efficiency.

[0056] Meanwhile, the position and spray angle of the spray assembly 51 can be flexibly adjusted according to the specific shape and size of the part to be cleaned 200, ensuring that the cleaning fluid can evenly cover all surfaces of the part to be cleaned 200 and avoid the generation of cleaning dead corners.

[0057] Please see Figure 6 , Figure 6 for Figure 2 A partially enlarged schematic diagram at point A. In some embodiments, the cleaning mechanism 5 includes: a jet assembly 52, which is disposed on the base 1 and located inside the second cleaning chamber 3. The jet assembly 52 is connected to an external air supply device to deliver cleaning gas to the soaked workpiece 200.

[0058] The jet assembly 52 is located on the base 1 and inside the second cleaning chamber 3, and is connected to an external air supply device. It can deliver cleaning gas to the soaked part 200 to be cleaned. When moisture or other liquids on the surface of the part 200 to be cleaned need to be removed quickly, the cleaning gas can blow away moisture and particles from the surface of the part 200 to be cleaned, preventing water stains and particle re-adhesion after cleaning.

[0059] Furthermore, the jet assembly 52 may include a mounting bracket disposed on the base 1 and a high-pressure gas nozzle facing the part to be cleaned. The gas nozzle is connected to an external gas supply device through a gas pipeline in the mounting bracket. The mounting bracket extends vertically so that cleaning gas is sprayed onto the part to be cleaned.

[0060] Furthermore, the jet assembly 52 can be used after the cleaning fluid spray to assist in drying, shortening the overall cleaning process time and improving production efficiency. The jet assembly 52 avoids the risk of corrosion or damage caused by cleaning fluid residue, further enhancing the applicability and reliability of the cleaning device 100.

[0061] In practice, depending on the material of the part to be cleaned 200, the type of dirt, and the cleaning requirements, the spray assembly 51 can be used alone, the jet assembly 52 can be used alone, or both can work together. This diversified cleaning method not only improves the cleaning effect but also expands the applicability of the cleaning device 100, enabling it to meet the cleaning needs of different industries and application scenarios.

[0062] Please see Figure 6 In some embodiments, the base 1 is provided with a plurality of positioning holes spaced apart along a first horizontal direction. The spray assembly 51 includes: a first spray member 511, the first spray member 511 including a connecting portion 5111 and a spray arm 5112, the connecting portion 5111 being fitted to the base 1, the connecting portion 5111 being provided with a strip-shaped hole 5111a extending along the first horizontal direction, the spray arm 5112 being connected to the connecting portion 5111, and the spray arm 5112 being connected to an external liquid supply device, and the spray arm 5112 having at least Part of the structure extends along a first horizontal direction so that the spray nozzle of the spray arm 5112 faces the part to be cleaned 200. The spray arm 5112 is configured to clean the outer surface of the part to be cleaned 200. Fastener 5113 is configured to pass through one of a plurality of positioning holes and a strip hole 5111a in sequence. The fastener 5113 is configured to press the connecting part 5111 against the base 1 to position the connecting part 5111 to the position corresponding to the positioning hole through which the fastener 5113 passes.

[0063] At least a portion of the spray arm 5112 extends along a first horizontal direction, ensuring that the spray liquid can uniformly cover the surface of the part 200 to be cleaned along the first horizontal direction. The connectivity between the spray arm 5112 and the external liquid supply equipment ensures a stable supply of cleaning liquid, making the spray cleaning process continuous and efficient.

[0064] The base 1 is provided with multiple positioning holes spaced apart along the first horizontal direction, providing flexibility for the installation and adjustment of the spray assembly 51. The first spray element 511 in the spray assembly 51 is attached to the base 1 via a connecting part 5111, and the strip hole 5111a on the connecting part 5111 engages with the positioning holes of the base 1, allowing the position of the spray assembly 51 to be adjusted according to the specific position and shape of the part 200 to be cleaned during installation. The adjustable installation method ensures that the spray nozzles can be precisely oriented towards the outer surface of the part 200 to be cleaned, achieving the best spraying effect regardless of changes in the size or shape of the part 200, thus improving the accuracy and adaptability of cleaning.

[0065] By sequentially inserting fasteners 5113 into the positioning holes of the base 1 and the strip holes 5111a of the spray component, the spray assembly 51 can be firmly fixed to the base 1, ensuring that the spray assembly 51 maintains a stable position and angle during operation. This fastening method not only facilitates installation and disassembly but also allows for quick adjustment of the position of the spray assembly 51 when needed to accommodate different sizes of the parts to be cleaned 200, thus improving the versatility and ease of use of the cleaning device 100.

[0066] Furthermore, when the spray assembly 51 requires maintenance or replacement, it can be easily removed for repair or replacement simply by loosening the fasteners 5113, reducing downtime and improving production efficiency. Replacing the spray assembly 51 with a new one does not require large-scale modifications to the entire cleaning device 100, thus reducing maintenance costs.

[0067] Please see Figure 6In some embodiments, the spray assembly 51 further includes: a second spray member 512, which includes a fixing member 5121, a movable member 5122, and a plurality of spray heads 5123. The fixing member 5121 is disposed on the base 1 and has a movable channel extending in a vertical direction and a fixing hole located on the side of the movable channel. The movable member 5122 is disposed in the movable channel and is movably disposed in the extension direction of the movable channel. The plurality of spray heads 5123 are all disposed on the movable member 5122. The plurality of spray heads 5123 have different spraying directions and are configured to extend into the interior of the part to be cleaned 200 in a second horizontal direction. The spray heads 5123 are used to communicate with an external liquid supply device to clean the inner or outer surface of the part to be cleaned 200. A clamping member 5124 is inserted through the fixing hole and is configured to abut against the outer peripheral surface of the movable member 5122 to fix the movable member 5122 and the movable channel relatively.

[0068] The fixing member 5121 of the second spray component 512 is mounted on the base 1. The movable channel of the fixing member 5121 allows the movable member 5122 to move vertically, thereby enabling vertical adjustment according to the height and shape of the part 200 to be cleaned. This allows the spray head 5123 to be precisely positioned to the internal or external parts of the part 200 to be cleaned, achieving optimal spraying results regardless of changes in the size of the part 200. Please refer to [link / reference]. Figure 7 , Figure 7 This is a schematic diagram of the structure of the second spray cleaning tank provided in the embodiment of this application. For the cleaning tank 202, the spray head 5123 can penetrate deep into the inside of the tank 202 to thoroughly clean the internal surface and ensure that there are no dead corners in the cleaning.

[0069] Multiple spray heads 5123 are mounted on the movable part 5122, and each sprays in a different direction, improving the comprehensiveness and efficiency of cleaning. The different spray directions can simultaneously cover multiple angles of the part to be cleaned 200, and this multi-angle spraying method effectively removes dirt and improves cleaning quality. Furthermore, multiple spray heads 5123 can work simultaneously to quickly complete the cleaning task.

[0070] The clamping member 5124 provides a stable fixation method for the spray assembly 51. By abutting against the outer peripheral surface of the movable member 5122 through the clamping member 5124, which passes through the fixing hole, the movable member 5122 can be securely fixed in the desired position. This not only ensures the stability of the spray head 5123 during the cleaning process, preventing positional displacement due to vibration or water flow impact, but also allows for quick adjustment of the spray head 5123's position. When it is necessary to change the cleaning object or adjust the spray angle, simply loosen the clamping member 5124, move the movable member 5122 to the appropriate position, and then clamp it again. The operation is simple and quick, improving the versatility and ease of use of the cleaning device 100.

[0071] Furthermore, the clamping element 5124 facilitates the maintenance and replacement of the spray head 5123. When the spray head 5123 becomes worn or clogged due to prolonged use, the movable part 5122 can be easily removed from the moving channel for maintenance or replacement. This reduces downtime of the cleaning device 100, improves production efficiency, and lowers maintenance costs.

[0072] Please see Figure 2 and Figure 8 , Figure 8 This is a schematic diagram of the clamping mechanism provided in an embodiment of this application. In some embodiments, a cleaning channel extending along a second horizontal direction is formed between the spray assembly 51 and the air jet assembly 52. ​​The clamping mechanism 4 includes: a clamping assembly 41 for clamping the part 200 to be cleaned; a rotating assembly 42 including a rotating shaft extending along the second horizontal direction, the rotating shaft being connected to the clamping assembly 41, and the rotating assembly 42 being configured to drive the clamping assembly 41 to rotate about the axis of the rotating shaft; and a moving assembly 43 including a movable structure and a fixed structure. The fixed structure is disposed on the base 1, and the movable structure is movably disposed on the fixed structure along the second horizontal direction. The movable structure is connected to the rotating assembly 42 to drive the rotating assembly 42 to move within the cleaning channel along the second horizontal direction.

[0073] A cleaning area is provided for the part to be cleaned 200 through a cleaning channel extending in the second horizontal direction formed between the spray assembly 51 and the air jet assembly 52. ​​The clamping assembly 41 of the clamping mechanism 4 can firmly fix the part to be cleaned 200, ensuring that the part to be cleaned 200 will not be displaced or shaken due to external force during the cleaning process, thereby ensuring the accuracy and stability of the cleaning.

[0074] The rotating component 42 has its rotation axis extending along a second horizontal direction and is connected to the clamping component 41, enabling the workpiece 200 to be cleaned to rotate around the axis of rotation. The rotation function allows the cleaning medium to contact all surfaces of the workpiece 200 in all directions, ensuring uniform and thorough cleaning of both the outer and inner surfaces, effectively avoiding the formation of cleaning dead zones and improving cleaning quality.

[0075] The movable component 43 enhances the flexibility and adaptability of the cleaning process. The movable structure is movably mounted on the fixed structure along the second horizontal direction, allowing the movable structure to drive the rotating component 42 to move. This enables the rotating component 42 to move the part to be cleaned 200 within the cleaning channel, allowing the part to be cleaned 200 to enter or leave the second receiving cavity. This makes the cleaning process more automated, reduces manual intervention, and improves the convenience and safety of operation.

[0076] Please see Figure 8Preferably, the rotating assembly 42 includes: a rotating bracket 421 disposed on the movable structure and extending in a vertical direction; and a rotating drive 422 disposed on the rotating bracket 421, the rotating drive 422 including a rotating shaft extending in a second horizontal direction, the rotating shaft being rotatably disposed on the rotating bracket 421, the rotating shaft being connected to the clamping assembly 41, and the rotating drive 422 being used to drive the clamping assembly 41 to rotate.

[0077] The rotary drive 422 enables the clamping assembly 41 to rotate around the axis of rotation. Driven by the rotary drive 422, the part to be cleaned 200 rotates continuously during the cleaning process, ensuring that the cleaning media from the spray assembly 51 and the air jet assembly 52 act evenly on all surfaces of the part to be cleaned 200. Furthermore, the connection between the rotation axis of the rotary drive 422 and the clamping assembly 41 ensures efficient force transmission and reduces energy loss. This makes the rotation smoother and more precise, further improving the cleaning effect.

[0078] Please see Figure 9 , Figure 9 This is a schematic diagram of the structure of the movable component provided in the embodiment of this application. Preferably, the fixed structure can be a lead screw 431 rotatably mounted on the base 1, extending along a second horizontal direction. The movable structure can be a nut slidably mounted on the lead screw 431, and the nut can be connected to a support frame 433, which supports the rotating component 42. The movable component 43 also includes a movable drive member 432, which is connected to the lead screw 431 and drives the lead screw 431 to rotate, thereby causing the nut to move along the extension direction of the lead screw 431.

[0079] The combination of lead screw 431 and nut provides linear motion control for the moving assembly 43. Lead screw 431 extends along a second horizontal direction and is rotatably mounted on the base 1, enabling it to convert rotational motion into linear motion, providing stable guidance and power transmission for the movement of the movable structure. The nut, as a movable structure, is slidably mounted on lead screw 431, allowing it to move smoothly along the extension direction of lead screw 431. The support frame 433 connected to the nut further enhances the load-bearing capacity, ensuring the stability of the rotating assembly 42 during movement and preventing a decrease in cleaning effectiveness or equipment damage due to vibration or uneven movement.

[0080] The motion drive 432 enhances the automation level of the moving assembly 43. Connected to the lead screw 431, the motion drive 432 rotates the lead screw 431, causing the nut to move along the extension direction of the lead screw 431. This not only enables precise displacement control but also allows for adjustment of the movement speed as needed. The motion drive 432 can be a stepper motor or a servo motor, which provides precise control and stable power output, further improving the reliability and cleaning quality of the cleaning device 100.

[0081] The transmission mechanism of the lead screw 431 and nut offers high transmission accuracy and stability, ensuring precise position control of the rotating assembly 42 during movement. The thread design of the lead screw 431 and the fit with the nut minimize friction during movement, reducing energy loss and improving transmission efficiency. Furthermore, the combination of the lead screw 431 and nut provides good load-bearing capacity, capable of supporting the weight of the rotating assembly 42 and the clamped workpiece 200, ensuring smooth movement throughout the entire process.

[0082] Furthermore, the moving component 43 also includes: a guide slide rail 434 disposed on the base 1, the guide slide rail 434 extending along a second horizontal direction; and a guide slider 435 slidably disposed on the guide slide rail 434 along the second horizontal direction, the guide slider 435 being connected to the support frame 433.

[0083] The guide rail 434 extends along a second horizontal direction and is disposed on the base 1, providing additional guidance and stabilization for the entire moving assembly 43. The guide slider 435 is connected to the support frame 433 and can slide along the guide rail 434, ensuring the straightness and stability of the support frame 433 when driving the rotating assembly 42. The cooperation between the guide rail 434 and the guide slider 435 effectively reduces swaying and offset during movement, improving the accuracy and reliability of the movement.

[0084] The combination of guide rail 434 and guide slider 435 complements the lead screw 431 and nut transmission system. The lead screw 431 and nut are responsible for converting rotary motion into linear motion and providing position control, while the guide rail 434 and guide slider 435 ensure the smoothness and accuracy of linear motion. This dual guiding mechanism improves the overall rigidity and load-bearing capacity of the moving assembly 43, enabling the rotating assembly 42 to remain stable even when carrying a heavy piece 200 to be cleaned during movement, avoiding swaying or jamming that may occur due to single-point support.

[0085] In addition, the moving component 43 also includes a limiting member 436 disposed on the guide rail 434. The limiting member 436 is used to restrict the movement of the guide slider 435 along the second horizontal direction and prevent the guide slider 435 from disengaging from the guide rail 434.

[0086] The limiting element 436 is disposed on the guide rail 434, which can effectively limit the movement range of the guide slider 435 in the second horizontal direction, preventing the guide slider 435 from accidentally disengaging from the guide rail 434. This enhances the safety of the cleaning device 100 operation and avoids damage to the cleaning device 100 or interruption of cleaning due to the guide slider 435 derailing. During the operation of the cleaning device 100, especially under high movement speed or heavy load, the presence of the limiting element 436 ensures that the guide slider 435 always moves within the effective range of the guide rail 434, reducing the risk of cleaning device 100 malfunction.

[0087] The limiting component 436 also helps improve the reliability and service life of the cleaning device 100. By limiting the range of movement of the guide slider 435, excessive wear between the guide rail 434 and the guide slider 435 can be reduced, avoiding component damage caused by movement exceeding the track range. This not only reduces the maintenance frequency and repair costs of the cleaning device 100, but also ensures the continuity and stability of the cleaning process, improving production efficiency.

[0088] Optionally, the limiting member 436 can be electrically connected to the control system of the moving drive member 432 to achieve more precise movement control. When the guide slider 435 approaches the limiting member 436, the control system can detect this signal and adjust the operating state of the moving drive member 432 in a timely manner, such as decelerating or stopping, thereby achieving more precise displacement control. This improves the automation level of the cleaning device 100 and enhances its operational flexibility and adaptability, enabling the cleaning device 100 to better cope with different cleaning tasks and changes in the specifications of the parts 200 to be cleaned.

[0089] Please see Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of the unfolded gripper structure provided in an embodiment of this application. Figure 11 This is a schematic diagram of the gripper retraction structure provided in an embodiment of this application. In some embodiments, the gripping assembly 41 includes: a gripping arm 411, a first end of which is connected to a rotation axis, and a second end of which extends along a second horizontal direction; a gripper, which includes a plurality of gripper portions 412, each of which is rotatably connected to the second end of the gripping arm 411, and the plurality of gripper portions 412 are spaced apart around the extension axis of the gripping arm 411. When the plurality of gripper portions 412 rotate around the gripping arm 411, the gripper can be in a retracted state that is close to each other or an extended state that is far apart from each other; and an adjusting ring 413, which is movably sleeved on the circumferential outer side of the gripper, and can move along the extension direction of the gripping arm 411. When the adjusting ring 413 is configured to move along the extension direction of the gripping arm 411, it forces the gripper portions 412 to rotate, so that the gripper retracts or expands.

[0090] The clamping assembly 41 includes a clamping arm 411, grippers, and an adjusting ring 413. The first end of the clamping arm 411 is connected to a rotating shaft, and the second end extends along a second horizontal direction, allowing the clamping arm 411 to rotate under the drive of the rotating shaft, while providing stable support and power transmission for the grippers. The grippers include multiple gripper portions 412, each rotatably connected to the second end of the clamping arm 411 and spaced apart around the extending axis of the clamping arm 411. This allows the gripper portions 412 to rotate under the drive of the clamping arm 411, enabling the grippers to retract and expand. The spaced arrangement of the multiple gripper portions 412 ensures a uniform distribution of clamping force, enabling the stable clamping of various shapes and sizes of parts 200 to be cleaned, preventing the parts 200 from shaking or falling off during the cleaning process due to unstable clamping.

[0091] The adjusting ring 413 is movably sleeved on the outer circumferential side of the gripper and can move along the extension direction of the clamping arm 411. When it is necessary to adjust the state of the gripper, the adjusting ring 413 is pushed or pulled along the clamping arm 411. The interaction between the adjusting ring 413 and the gripper part 412 forces the gripper part 412 to rotate around the connection point with the clamping arm 411. When the adjusting ring 413 moves toward the clamping direction of the gripper part 412, the gripper part 412 is forced to rotate inward, so that the gripper is in a closed state, for clamping the part to be cleaned 200. Conversely, when the adjusting ring 413 moves toward the root of the gripper part 412, the gripper part 412 rotates outward, so that the gripper is in an open state, making it easy to place or remove the part to be cleaned 200. This adjustment method is simple to operate. Only the position of the adjusting ring 413 needs to be adjusted to open and close the gripper. No complicated tools or operating steps are required, which improves the ease of use and operating efficiency of the clamping assembly 41.

[0092] Optionally, the gripper portion 412 and the adjusting ring 413 can be connected by threads to ensure the reliability of the connection between the gripper portion 412 and the adjusting ring 413.

[0093] The clamping assembly 41 improves the flexibility and adaptability of clamping, and also enhances the stability and reliability of clamping. The movement of the adjusting ring 413 enables the jaws to retract and expand, allowing the clamping force to be adjusted according to the shape and size of the workpiece 200 to ensure stable clamping. Simultaneously, the multi-point contact design of the jaws evenly distributes the clamping force, reducing pressure on the surface of the workpiece 200 and lowering the risk of surface damage due to excessive clamping force. This is particularly suitable for workpieces 200 with fragile surfaces or high precision requirements. Furthermore, the rotatable connection of the jaws allows the clamping assembly 41 to adapt to workpieces 200 of different shapes, improving its versatility and applicability.

[0094] Preferably, the gripper portion 412 may include a first sub-portion 4121 and a second sub-portion 4122. The first sub-portion 4121 is rotatably connected to the second end of the gripping arm 411, and an adjusting ring 413 is movably sleeved on the first sub-portion 4121. The second sub-portion 4122 is parallel to the gripping portion of the first sub-portion 4121, and the first sub-portion 4121 and the second sub-portion 4122 are connected by a bolt 4123. The gap between the first sub-portion 4121 and the second sub-portion 4122 can grip the edge of the workpiece 200 to be cleaned, and the gripping force can be adjusted by rotating the bolt 4123.

[0095] The second sub-part 4122 is parallel to the clamping portion of the first sub-part 4121 and is connected by bolts 4123. This parallel design ensures a uniform distribution of clamping force, effectively reducing pressure on the surface of the workpiece 200 to be cleaned and lowering the risk of surface damage caused by uneven clamping force. Simultaneously, the gap between the first sub-part 4121 and the second sub-part 4122 can be flexibly adjusted to accommodate workpieces 200 of varying thicknesses. By rotating bolts 4123, the distance between the first sub-part 4121 and the second sub-part 4122 can be controlled, thereby adjusting the clamping force to ensure clamping stability and prevent damage caused by excessive clamping force.

[0096] Optionally, the second sub-part 4122 and the first sub-part 4121 may be provided with a soft protective material to prevent damage to the workpiece 200 when it is clamped.

[0097] Please see Figure 12 , Figure 12 This is a schematic diagram of the structure of the steel brush provided in an embodiment of this application. In some embodiments, the spray assembly 51 further includes a steel brush 53, which is disposed on the spray arm 5112 and configured to contact the outer wall of the part to be cleaned 200 so as to wipe the outer surface of the part to be cleaned 200 when the part to be cleaned 200 and the steel brush 53 move relative to each other.

[0098] A steel brush 53 is positioned on the spray arm 5112 and contacts the outer wall of the part to be cleaned 200, introducing mechanical friction during the cleaning process and enhancing the cleaning effect. When the part to be cleaned 200 moves relative to the steel brush 53 under the rotation of the rotating assembly 42, the hard bristles of the steel brush 53 can effectively wipe the outer surface of the part to be cleaned 200, removing stubborn dirt and impurities adhering to it. This mechanical scrubbing action is suitable for removing deposits that are difficult to rinse off with liquid alone, improving the thoroughness and cleanliness of the cleaning.

[0099] The combination of steel brush 53 and spray assembly 51 achieves a synergistic effect of mechanical and chemical cleaning. The high-pressure cleaning fluid sprayed by spray arm 5112 softens and washes away some of the dirt, while the wiping action of steel brush 53 further breaks down the adhesion between the dirt and the surface of the part to be cleaned 200, making stubborn dirt easier to rinse away. This dual cleaning mechanism not only improves cleaning efficiency but also reduces the amount of cleaning fluid used.

[0100] The steel brush 53 further enhances the adaptability and flexibility of the cleaning process. By adjusting the installation position and angle of the steel brush 53, it can be ensured that the steel brush 53 makes full contact with the surfaces of the parts 200 to be cleaned, regardless of their type or shape, thus guaranteeing effective wiping. Furthermore, the pressure of the steel brush 53 can be adjusted as needed to accommodate different materials of the parts 200 to be cleaned, ensuring cleaning effectiveness while preventing scratches or damage to the surface of the parts 200 caused by excessively stiff bristles or excessive pressure.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
