Description

Technical Field

[0001] This invention relates to the field of parts cleaning technology, specifically a cleaning device for cleaning small parts. Background Technology

[0002] In the automotive manufacturing and after-sales maintenance sector, the cleaning of various precision small parts is a crucial process for ensuring product assembly accuracy, operational reliability, and service life. During machining, assembly, or disassembly and repair, these parts are prone to surface contamination with cutting fluid, oil, metal shavings, dust, and other impurities, placing stringent industry requirements on cleanliness. Existing cleaning processes and equipment for automotive small parts mostly employ immersion cleaning and external fixed spray cleaning methods. Immersion cleaning suffers from low cleaning efficiency, easy secondary contamination of impurities, and substandard cleanliness. Conventional spray cleaning devices typically have their spray mechanisms located in fixed positions within the cleaning chamber, unable to penetrate deep into the parts' loading containers, resulting in limited spray coverage. For stacked small parts, the contact surfaces and inner layers are prone to forming cleaning dead zones, making comprehensive and effective rinsing difficult. Manual assistance in turning over these parts is often required, increasing labor costs and working time, and also increasing the risk of surface damage and precision loss. These methods fail to meet the automotive industry's demand for high-volume, high-cleanliness, and low-damage cleaning of small parts.

[0003] Meanwhile, the loading structures of existing automotive small parts cleaning equipment are mostly fixed-volume integrated material frames, which cannot flexibly adjust the loading space according to the batch size and shape of the parts to be cleaned. When the load of parts is small, they are prone to significant movement and collision during the cleaning process, causing damage to the parts; when the load of parts is large, they are prone to excessive stacking, further aggravating the formation of cleaning dead corners and significantly reducing the cleaning effect. In addition, the rinsing mechanism of existing cleaning devices is limited by the installation position and structure, and cannot act on the parts to be cleaned at close range and over a large area. The hydraulic attenuation of the spray water flow is serious, and the rinsing force is insufficient. It is difficult to effectively remove strongly adhered oil stains and metal debris, resulting in poor cleanliness stability of the cleaned parts and a high rework rate. This seriously restricts the work efficiency and quality of the automotive small parts cleaning process. For the above content, please refer to Figure 1 . Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for cleaning small parts, so as to solve the problems mentioned in the background art.

[0008] Preferably, the housing has at least two limiting holes, which are used to limit the adjustment baffle when the insert rod is inserted.

[0009] Preferably, both the housing and the adjusting baffle are provided with inlet and outlet holes, which are used to allow water to rinse small parts and to discharge wastewater after cleaning.

[0010] Preferably, the rinsing mechanism includes a fixed rinsing plate and a movable rinsing plate; The fixed rinsing plate has a movable groove, and the movable rinsing plate is disposed in the movable groove.

[0011] Preferably, the fixed rinsing plate is provided with a support block, and there are at least two support blocks, which are respectively provided on both sides of the movable groove; A lead screw is provided on the bearing block, and the lead screw passes through a sleeve, which is located on the movable flushing plate.

[0014] Preferably, the rinsing mechanism is provided with a driving mechanism, which is used to drive the rinsing mechanism to move up and down; The drive mechanism includes a frame disposed on the housing, and a second drive component connected to the rinsing mechanism is disposed in the frame.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: This cleaning device for small parts achieves significant performance improvements and scenario adaptability to the cleaning needs of small automotive parts. Its flexibly adjustable internal loading space perfectly accommodates small automotive parts of different sizes and loading capacities, effectively preventing damage from movement and collisions during the cleaning process, and also preventing excessively thick stacking of parts from creating cleaning blind spots, thus ensuring the adaptability and stability of the cleaning operation. The deep-penetrating flushing structure significantly shortens the distance between the spray end and the parts to be cleaned, greatly reducing the hydraulic attenuation of the spray water flow and ensuring sufficient flushing force, effectively removing stubborn impurities such as oil stains and metal shavings adhering to the surface of the parts. Simultaneously, the combination of fixed and mobile spray structures greatly expands the spray coverage area, achieving large-area, no-dead-angle flushing of parts within the loading box, significantly improving cleaning cleanliness and efficiency, reducing the rework rate of parts cleaning, and fully meeting the automotive industry's requirements for large-volume, high-cleanliness, and low-damage cleaning of small parts.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 This invention provides a technical solution: a cleaning device for cleaning small parts, comprising a housing 1 for cleaning small parts, a bottom chamber 11 connected to the housing 1, a drainage channel connected to the bottom of the bottom chamber 11, a rinsing chamber 12 connected to the bottom chamber 11, the rinsing chamber 12 for rinsing the small parts in a carrying box 2 and washing away stains, and a drying chamber 13 connected to the bottom chamber 11, and the drying chamber 13 and the rinsing chamber 12 are interconnected, the drying chamber 13 for drying the small parts inside the carrying box 2 after rinsing. The bottom chamber 11 is also provided with a feed inlet 14 for allowing the carrying box 2 to enter the rinsing chamber 12 and subsequently the drying chamber 13. One side of the drying chamber 13 is connected to the rinsing chamber 12, and the other side is provided with a discharge outlet 18 for discharging the rinsed and dried small parts. There are at least three rinsing chambers 12 arranged longitudinally. All rinsing chambers 12 and the drying chamber 13 have baffles 16 on both sides. The baffles 16 separate the rinsing chambers 12 and the drying chambers 13, preventing water and airflow from overflowing and affecting the rinsing and drying effects. A first pushing member 17 is provided on the baffle 16 to drive it to move, opening and closing the rinsing chambers 12 and the drying chambers 13. Observation windows 15 are also provided on the rinsing chambers 12 and the drying chambers 13 to observe the scene inside, thereby monitoring the rinsing and drying effects. Cleaning devices are installed in the rinsing chambers 12, and the number of cleaning devices is the same as the number of rinsing chambers 12.

[0020] The carrier box 2 is fed into the outer shell 1 through the feed inlet 14. The first pusher 17 drives the baffle 16 to perform an opening and closing action, realizing the switching of the workstations of each rinsing chamber 12 and drying chamber 13. The carrier box 2 enters at least three longitudinally arranged rinsing chambers 12 in sequence. The cleaning device in each rinsing chamber 12 simultaneously performs rinsing operations on the small parts in the carrier box 2, washing away the stains attached to the surface of the parts. The bottom chamber 11 receives the wastewater generated by the rinsing operation and discharges it through the drainage channel wrapped at the bottom. After the rinsing operation of a single workstation is completed, the first pusher 17 drives the corresponding baffle 16 to perform an opening and closing action. 6. Open the transfer channel to allow the carrier box 2 to transfer to the next station. The baffle 16 throughout the process can isolate adjacent cavities to prevent water and air from overflowing and causing mutual interference between the rinsing and drying effects. After the carrier box 2 has completed the entire rinsing process, it enters the drying chamber 13 connected to the rinsing chamber 12. The drying chamber 13 performs blower drying on the small parts after rinsing. Finally, the small parts that have completed the entire cleaning and drying process are discharged with the carrier box 2 through the discharge port 18. The internal working status can be monitored in real time through the observation windows 15 set on the rinsing chamber 12 and the drying chamber 13 to ensure the rinsing and drying effects.

[0021] The cleaning device for cleaning small parts also includes: The carrier box 2 is placed inside the outer shell 1. The carrier box 2 is used to load small parts and includes a shell 21 and adjusting baffles 24 disposed in the shell 21. The shell 21 is hollow and has inlet / outlet holes 23. The adjusting baffles 24, together with the shell 21, form a space for loading small parts. There are two adjusting baffles 24, both disposed in the shell 21. Both the shell 21 and the adjusting baffles 24 have inlet / outlet holes 23, which are used to allow water to rinse the small parts and to drain the wastewater after cleaning. There is a space between the two adjusting baffles 24, which is connected by a movable flushing plate 42. The spray nozzles 49 on both sides of the movable flushing plate 42 are used to spray water to rinse and clean the adjusting baffles 24 on both sides.

[0022] The carrier box 2, through its hollow shell 21 and two built-in adjustable baffles 24, forms a loading space to stably load the small parts to be cleaned. During the cleaning operation, the inlet and outlet holes 23 on both the shell 21 and the adjustable baffles 24 allow for the smooth entry of external rinsing water and the rapid discharge of wastewater after cleaning, ensuring that the rinsing medium can fully contact the small parts in the loading space and effectively wash away the dirt on the surface of the parts. At the same time, the reserved insertion space between the two adjustable baffles 24 can form an insertion fit with the movable rinsing plate 42. When the movable rinsing plate 42 is inserted into this space, the spray nozzles 49 on both sides can simultaneously spray rinsing water onto the adjustable baffles 24 on both sides, simultaneously completing the rinsing and cleaning of the adjustable baffles 24. This achieves the linkage operation of cleaning small parts and self-cleaning of the carrier structure, ensuring comprehensive coverage and efficient execution of the cleaning operation.

[0023] The adjusting baffle 24 is equipped with a connecting rod 25. One end of the connecting rod 25 is connected to a limiting piece 26. A handle 27 is provided on one side of the limiting piece 26. The handle 27 is used to operate the adjusting baffle 24, allowing it to slide in the first groove 22 in the housing 21. The housing 21 has a first groove 22, which is a two-layer groove. The limiting piece 26 can be engaged in the first layer of the first groove 22, and the connecting rod 25 passes through the second layer of the first groove 22. The handle 27 is used to operate the adjusting baffle 24 to slide in the first groove 22, thereby adjusting its position in the housing 21 according to the size of the small parts loaded in the housing 21, to adapt to the size of the small parts. The handle 27 has a connecting hole into which a rod 210 is inserted. The rod 210 is inserted into a limiting hole 211 to limit the position of the adjusting baffle 24. A connecting plate 29 is connected to the middle of the rod 210 to fix the reset piece 291. An elastic reset piece 291, which is a compression spring, is connected between the handle 27 and the connecting plate 29. One end of the rod 210 is connected to a control plate 28 for operating the rod 210. Pulling the control plate 28 compresses the reset piece 291, thereby pulling the rod 210 out of the limiting hole 211 to adjust the position of the adjusting baffle 24. After the adjusting baffle 24 is in the correct position, the rod 210 is inserted back into the limiting hole 211. The housing 21 has at least two limiting holes 211 for the rod 210 to be inserted into to limit the position of the adjusting baffle 24.

[0024] By pulling the control panel 28, the inserted rod 210 fixed thereto can be moved axially synchronously, simultaneously squeezing the elastic reset member 291 set between the handle 27 and the connecting plate 29 in the middle of the inserted rod 210, so that the inserted rod 210 is pulled out from the limiting hole 211 on the housing 21, quickly releasing the limiting lock on the adjusting baffle 24; then, by gripping the handle 27 and applying force, the driving force can be transmitted through the connecting rod 25 fixed to the adjusting baffle 24, causing the adjusting baffle 24 to slide smoothly along the first sliding groove 22 opened in the housing 21. The two-layer groove structure of the first sliding groove 22 can respectively connect with the connecting rod 25 passing through it and the limiting piece 26 connected to the end of the connecting rod 25. The system forms an adaptive guide and anti-detachment limit to ensure the stability and smoothness of the sliding adjustment process. By sliding and adjusting the relative positions of the two adjusting baffles 24 in the hollow box shell 21, the size of the loading space can be flexibly changed to accommodate small parts of different specifications loaded in the box shell 21. When the adjusting baffles 24 are adjusted to the target position, the control plate 28 is released, and the compressed reset piece 291 immediately releases its elastic reset force, pushing the connecting plate 29 and the insertion rod 210 to move in the opposite direction and reset, so that the insertion rod 210 is accurately inserted into the corresponding position limit hole 211, completing the position locking of the adjusting baffles 24, and realizing the full-process linkage operation of the size adaptation adjustment and locking limit of the loading space.

[0025] Example 1: By pulling the control panel 28, the rod 210 fixed to it can be moved axially synchronously, simultaneously squeezing the elastic reset member 291 set between the handle 27 and the connecting plate 29 in the middle of the rod 210, so that the rod 210 is pulled out from the limiting hole 211 on the housing 21, quickly releasing the limiting lock on the adjusting baffle 24; then, by gripping the handle 27 and applying force, the driving force can be transmitted through the connecting rod 25 fixed to the adjusting baffle 24, causing the adjusting baffle 24 to slide smoothly along the first sliding groove 22 opened in the housing 21, wherein the first sliding groove 22 The two-layer groove structure of the groove 22 can respectively form a matching guide and anti-disengagement limit with the connecting rod 25 passing through it and the limiting piece 26 connected to the end of the connecting rod 25, ensuring the stability and smoothness of the sliding adjustment process. By sliding and adjusting the relative position of the two adjusting baffles 24 in the hollow box shell 21, the size of the loading space can be flexibly changed to accommodate small parts of different specifications loaded in the box shell 21. When the adjusting baffle 24 is adjusted to the target position, the control plate 28 is released, and the compressed reset piece 291 immediately releases the elastic reset force, pushing the connecting plate 29 and The insertion rod 210 is reversed and reset, allowing it to be precisely inserted into the corresponding limiting hole 211, thus locking the position of the adjusting baffle 24. This allows the two adjusting baffles 24 to cooperate with the hollow housing 21 to form a stable loading space that matches the specifications of the small parts to be cleaned, ensuring stable loading of the small parts. During subsequent cleaning operations, the inlet and outlet holes 23 on both the housing 21 and the adjusting baffles 24 allow for the smooth entry of external flushing water and the rapid discharge of wastewater after cleaning, ensuring that the flushing medium can fully contact the loading space. The small parts are effectively rinsed to remove dirt from their surfaces. At the same time, the reserved insertion space between the two adjusting baffles 24 can be inserted into the movable flushing plate 42. When the movable flushing plate 42 is inserted into the space, the spray nozzles 49 on both sides can spray flushing water onto the adjusting baffles 24 on both sides simultaneously, thus completing the flushing and cleaning of the adjusting baffles 24. This achieves a full-process linkage operation of loading space size adaptation adjustment, locking limit and small parts cleaning, and self-cleaning of the load-bearing structure, ensuring the adaptability, comprehensiveness and efficient execution of the cleaning operation.

[0026] The rinsing mechanism 4 can be inserted into the carrier box 2 to rinse a large area of ​​small parts loaded in the carrier box 2. The rinsing mechanism 4 includes a fixed rinsing plate 41 and a movable rinsing plate 42. The fixed rinsing plate 41 has a water spray nozzle 49 on its inner side, and the movable rinsing plate 42 has water spray nozzles 49 on both sides. This allows for targeted rinsing of the small parts loaded in the carrier box 2 from both sides. Compared with the original cleaning device, the thickness of the loaded parts is smaller, and the small parts on the inner side can also be cleaned. The fixed rinsing plate 41 has a movable groove 410, which is the range of movement of the movable rinsing plate 42. This allows for adjustment according to the different positions of the adjusting baffle 24. The movable rinsing plate 42 is located in the movable groove 410.

[0027] When the rinsing mechanism 4 performs the rinsing operation, it is inserted entirely into the carrier box 2. The spray nozzles 49 on the inner side of the fixed rinsing plate 41 continuously spray rinsing water to form a stable single-sided rinsing working surface. At the same time, the movable rinsing plate 42 can rely on the movable groove 410 opened on the fixed rinsing plate 41 to adaptively adjust its position within the stroke range limited by the movable groove 410 according to the adjustment position of the adjusting baffle 24 in the carrier box 2. It accurately inserts into the reserved space between the two adjusting baffles 24. After adjustment, the spray nozzles 49 on both sides of the movable rinsing plate 42 spray water synchronously to both sides. The washing water flow, together with the spray nozzles 49 of the fixed rinsing plate 41, forms a multi-dimensional and multi-working-surface rinsing coverage, significantly reducing the loading thickness of small parts in a single rinsing area. This allows the rinsing water flow to fully penetrate and contact the small parts inside the loading area, achieving targeted rinsing of both sides of the small parts in the carrying box 2. This thoroughly washes away the stains attached to the surface of the parts and simultaneously cleans the adjusting baffle 24. Through the linkage and coordination of the fixed rinsing of the fixed rinsing plate 41 and the adaptive adjustment rinsing of the moving rinsing plate 42, the comprehensiveness and thoroughness of the rinsing operation are significantly improved.

[0028] The fixed rinsing plate 41 is provided with four support blocks 43, arranged in pairs. Each pair of support blocks 43 is connected to a lead screw 45, for a total of two lead screws 45, which are respectively connected to both ends of the sleeve 46. There are at least two support blocks 43, which are respectively located on both sides of the movable groove 410. The support blocks 43 are provided with lead screws 45, which pass through the sleeve 46, which is located on the movable rinsing plate 42. The support blocks 43 are also provided with a motor 44 to drive the lead screws 45 to rotate. When the motor 44 drives the two lead screws 45 to rotate, it can drive the sleeve 46 to move in the movable groove 410, thereby adapting to the center position between the two adjusting baffles 24. The socket 46 is also provided with a roller 47, which is used to support the socket 46 and can rotate to reduce the friction of the socket 46 on the fixed rinsing plate 41 when it moves. The fixed rinsing plate 41 is provided with a second sliding groove 48, and the roller 47 is located in the second sliding groove 48. The second sliding groove 48 is also used to limit the movement of the roller 47.

[0029] After the motor 44 starts, it outputs rotational driving force, synchronously driving the lead screws 45 mounted on the two sets of bearing blocks 43 to rotate synchronously. The rotating lead screws 45, through the threaded transmission with the through-connected sleeve 46, convert the rotational motion into linear displacement, thereby driving the movable rinsing plate 42, which is fixedly connected to the sleeve 46, to complete a precise linear displacement along the movable groove 410 of the fixed rinsing plate 41. This allows it to match the center position between the two adjusting baffles 24 in the bearing box 2, providing precise alignment for subsequent insertion rinsing. During the process of the sleeve 46 driving the movable rinsing plate 42 to move, the rollers 47 mounted on the sleeve 46 move synchronously. As the roller 47 moves, it rolls within the second groove 48 on the fixed rinsing plate 41. The second groove 48 guides and limits the roller 47 throughout its movement, preventing swaying during displacement. At the same time, the roller 47 significantly reduces the frictional resistance between the sleeve 46 and the fixed rinsing plate 41 through rolling friction, ensuring smooth and stable displacement adjustment. Through the full structural linkage of power drive, threaded transmission, guide resistance reduction, and precise alignment, the position of the moving rinsing plate 42 is adaptively and precisely adjusted, perfectly matching the spacing of the adjustment baffles 24 corresponding to different specifications of parts, providing stable support for subsequent comprehensive and efficient rinsing operations.

[0030] Please refer to Figure 3 The drive mechanism 3 includes a frame 31 mounted on the outer shell 1. The frame 31 is used to protect the second drive member 32. The second drive member 32 is connected to the rinsing mechanism 4 and is used to drive the rinsing mechanism 4 to move up and down. The frame 31 is provided with the second drive member 32 connected to the rinsing mechanism 4, so as to drive the rinsing mechanism 4 and insert the rinsing mechanism 4 into the carrier box 2.

[0031] In Example 2, after the second drive unit 32 installed inside the frame 31 is started, it outputs a vertical linear drive force, driving the flushing mechanism 4 fixed to it to complete a precise lifting and lowering displacement, driving the flushing mechanism 4 to be inserted into the carrier box 2 as a whole, completing the feeding action of the flushing operation; then the motor 44 of the flushing mechanism 4 starts, outputting a rotational drive force to synchronously drive the lead screws 45 mounted on the two sets of carrier blocks 43 to rotate synchronously. The rotating lead screws 45 are connected to the threaded transmission formed by the through-connected sleeve 46, converting the rotational motion into linear displacement, thereby driving the movable flushing plate 42 fixedly connected to the sleeve 46 to complete a precise linear displacement along the movable groove 410 of the fixed flushing plate 41. During this process, the rollers 47 installed on the sleeve 46 move synchronously and roll in the second sliding groove 48 opened in the fixed flushing plate 41, which not only prevents displacement deviation through the guide limit of the second sliding groove 48, but also rolls. Friction significantly reduces movement resistance, ensuring a smooth and stable displacement process. Ultimately, the moving flushing plate 42 precisely adapts to the center position between the two adjusting baffles 24 inside the carrying box 2, completing the precise alignment of the flushing station. After alignment, the water spray nozzles 49 on the inner side of the fixed flushing plate 41 and the water spray nozzles 49 on both sides of the moving flushing plate 42 simultaneously spray flushing water, forming a multi-dimensional, multi-working-surface flushing coverage. This significantly reduces the loading thickness of small parts in a single flushing area, allowing the flushing water to fully penetrate and contact the small parts inside the loading area. This achieves targeted flushing of the small parts inside the carrying box 2 on both sides, thoroughly rinsing away the stains attached to the surface of the parts. Simultaneously, it completes the flushing and cleaning of the adjusting baffles 24. Through the coordinated operation of the entire structure, including feed drive, adaptive station adjustment, and simultaneous flushing of multiple working surfaces, the accuracy, comprehensiveness, and thoroughness of the flushing operation are significantly improved.

[0032] When using the cleaning device for cleaning small parts, pulling the control plate 28 causes the rod 210 fixed to it to move axially in sync, simultaneously squeezing the elastic reset piece 291 set between the handle 27 and the connecting plate 29 in the middle of the rod 210, so that the rod 210 is pulled out from the limiting hole 211 on the housing 21, releasing the limiting lock on the adjusting baffle 24. By holding the handle 27 and applying force, the driving force is transmitted through the connecting rod 25 fixed to the adjusting baffle 24, causing the adjusting baffle 24 to slide smoothly along the first sliding groove 22 opened in the housing 21. The two-layer groove structure of the first sliding groove 22 can respectively form a matching guide and anti-disengagement limiting with the connecting rod 25 passing through it and the limiting piece 26 connected to the end of the connecting rod 25. By sliding and adjusting the two adjusting baffles 24. Within the hollow housing 21, the relative position of the loading space can be flexibly adjusted to accommodate small parts of different specifications to be cleaned. After adjusting to the target position, the control panel 28 is released, and the compressed reset component 291 releases its elastic reset force, pushing the connecting plate 29 and the insertion rod 210 to move in the opposite direction and reset. This allows the insertion rod 210 to be precisely inserted into the corresponding limiting hole 211, completing the position locking of the adjusting baffle 24. This allows the two adjusting baffles 24 to cooperate with the housing 21 to form a stable loading space that matches the specifications of the parts. After loading the small parts to be cleaned, the carrier box 2 is fed into the outer shell 1 through the feed port 14. The first pusher 17 drives the baffle 16 to perform opening and closing actions, realizing the switching of the work positions of each rinsing chamber 12 and drying chamber 13. The carrier box 2 enters sequentially. Within the at least three longitudinally arranged rinsing chambers 12, baffles 16 isolate adjacent chambers to prevent water and airflow from overflowing and interfering with the rinsing and drying effects. After the carrier box 2 is in place, the second drive unit 32 installed in the frame 31 is activated, outputting vertical linear drive force to drive the rinsing mechanism 4 fixed to it to complete precise lifting and lowering displacement. The rinsing mechanism 4 is then inserted into the carrier box 2 to complete the rinsing feed action. Subsequently, the motor 44 of the rinsing mechanism 4 is activated, outputting rotational drive force to synchronously drive the lead screws 45 mounted on the two sets of carrier blocks 43 to rotate synchronously. The rotating lead screws 45, through the threaded transmission with the through-connected sleeve 46, convert the rotational motion into linear displacement, thereby driving the moving rinsing plate 4 fixedly connected to the sleeve 46. 2. The moving flushing plate 42 completes precise linear displacement along the movable groove 410 of the fixed flushing plate 41. During this process, the rollers 47 installed on the sleeve 46 move synchronously and roll within the second sliding groove 48 opened in the fixed flushing plate 41. The second sliding groove 48 guides and limits the displacement to avoid swaying, and the rolling friction greatly reduces the moving resistance, ensuring a smooth and stable displacement process. Finally, the moving flushing plate 42 is precisely fitted to the center position between the two adjusting baffles 24 in the carrying box 2 and inserted into the reserved space. After the alignment is completed, the water spray nozzles 49 set on the inner side of the fixed flushing plate 41 and the water spray nozzles 49 set on both sides of the moving flushing plate 42 spray flushing water synchronously, forming a multi-dimensional and multi-working-surface flushing coverage, which greatly reduces the loading thickness of small parts in a single flushing area.The rinsing water flows through the inlet and outlet holes 23 on both the housing 21 and the adjusting baffle 24, fully contacting the small parts in the loading space to thoroughly rinse and remove dirt adhering to the surface of the parts. Simultaneously, the adjusting baffle 24 is cleaned. Wastewater generated during rinsing is collected by the bottom chamber 11 and discharged through a drainage channel enclosed at the bottom. After the single-station rinsing operation is completed, the first pusher 17 drives the corresponding baffle 16 to open the flow channel, causing the carrier box 2 to flow to the next station. The carrier box 2, having completed the multi-stage rinsing process, enters the drying chamber 13, which is connected to the rinsing chamber 12. The drying chamber 13 performs a forced-air drying operation on the rinsed small parts. Finally, the small parts, having completed the entire cleaning and drying process, are discharged with the carrier box 2 through the outlet 18. Throughout the operation, the internal operating status can be monitored in real time through the observation windows 15 set on the rinsing chamber 12 and the drying chamber 13 to ensure the rinsing and drying effects.
