Description

Technical Field

[0001] This invention relates to the field of parts cleaning technology, and specifically to a parts cleaning machine with a multi-station parallel cleaning tank that can move. Background Technology

[0002] In the industrial production field, during the processing, assembly and storage of parts, contaminants such as oil, cutting chips, dust and oxide scale are easily attached to the surface. If these contaminants are not removed in time, they will directly affect the assembly accuracy, performance and service life of the parts. Therefore, effective cleaning of parts is one of the key links to ensure product quality.

[0003] Typically, the cleaning process for parts involves three core steps: preliminary cleaning, fine cleaning, and rinsing. Preliminary cleaning primarily targets contaminants adhering to the surface of the parts, laying the foundation for subsequent cleaning steps. Fine cleaning focuses on removing contaminants remaining on the surface of the parts and in complex structures such as deep holes and crevices. Rinsing, as the final step, aims to remove residual cleaning solution and chemicals from the surface of the parts, preventing these residues from forming new stains or causing corrosion after drying.

[0004] Currently, the three cleaning steps mentioned above are performed in a step-by-step manner in most production scenarios. That is, after the parts have completed the preliminary cleaning, they must wait for the previous batch of parts to complete the fine cleaning and leave the fine cleaning tank before they can enter the fine cleaning stage. Similarly, the parts that have completed the fine cleaning must wait for the rinsing tank to be empty before they can enter the rinsing stage. However, this step-by-step operation method has obvious technical limitations: due to the different process characteristics of the preliminary cleaning, fine cleaning and rinsing, the time consumed by each step varies significantly. Among them, fine cleaning, which needs to deal with stubborn contaminants and involves complex physicochemical reactions, often takes the longest time. This results in the parts that have completed the preliminary cleaning having to wait in the temporary storage area for a long time until the fine cleaning tank is empty before they can enter the next stage, which greatly prolongs the cycle of the overall cleaning process and reduces cleaning efficiency. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a multi-station parallel cleaning tank movable parts cleaning machine. This effectively solves the problems in traditional step-by-step parts cleaning operations where, after initial cleaning, parts must wait for the previous batch to leave the fine cleaning tank before entering fine cleaning, and after fine cleaning, they must wait for the rinsing tank to become empty before entering rinsing. The significant differences in time consumption between each step result in long waiting times for parts, extending the overall cleaning cycle and reducing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a multi-station parallel cleaning tank movable parts cleaning machine, comprising:

[0008] The housing is divided into a rough washing chamber, a fine washing chamber, a rinsing chamber and a collection chamber from top to bottom by a partition. A rotating shaft driven by a servo motor is fixedly connected to the center of the partition. Each of the rough washing chamber, fine washing chamber, rinsing chamber and collection chamber is equipped with a cleaning tank. The cleaning tank is equipped with a support component and a cleaning device is connected to the bottom of the cleaning tank.

[0009] Among them, the cleaning bucket in the rough washing chamber is fixedly connected to the first partition above, and an annular seat is fixedly connected to the rotating shaft in the rough washing chamber. The inner wall of the annular seat is provided with a guide groove to guide the support component therein to rotate and tilt.

[0010] The washing chamber contains multiple cleaning tubs, which are fixedly connected to the rotating shaft via a connecting frame. An annular seat II is fixedly connected to the machine casing inside the washing chamber via a connecting plate. The inner wall of the annular seat II is provided with a guide groove II that allows the supporting components in the washing chamber to rotate.

[0011] The rinsing chamber has the same structure as the roughing chamber, and each of the three partitions below is connected to a drain assembly.

[0012] Furthermore, the support assembly includes a mounting rod, which is arranged radially along the cleaning bucket and rotatably connected to the cleaning bucket. A guide rod is slidably connected to the mounting rod, and a support plate is fixedly connected to the upper end of the guide rod. The support plate has multiple through holes and is connected to the mounting rod through a buffer spring.

[0013] Furthermore, wedges are symmetrically fixedly connected to the lower end of the support plate, and symmetrical insertion holes adapted to the wedges are provided on the mounting rod.

[0014] Furthermore, a locking component is fixedly connected to the inner wall of the cleaning bucket, and a lock hole is vertically opened on the locking component. An arc-shaped locking rod that cooperates with the lock hole pin is fixedly connected to the lower end face of the support plate.

[0015] Furthermore, a rotating handle is fixedly connected to one end of the mounting rod away from the central axis of the housing, and a guide block is fixedly connected to the rotating handle.

[0016] Furthermore, the bottom plate of the annular seat is uniformly and circumferentially connected with a discharge channel, the number of which is the same as the number of cleaning tubs in the fine washing chamber. A discharge trough corresponding to the discharge channel is provided on the partition below the discharge channel. The guide trough adopts a closed-loop design and is composed of horizontal sections and V-shaped sections that are staggered and interconnected. The number of V-shaped sections is the same as the number of cleaning tubs in the fine washing chamber. The guide blocks in the rough washing chamber and the rinsing chamber are slidably connected in the corresponding guide trough.

[0017] Furthermore, the bottom plate of the annular seat two is fixedly connected to the discharge channel two, and the partition plate below the discharge channel two is also provided with a discharge groove corresponding to the discharge channel two. The guide groove two adopts a closed-loop design and is composed of a corrugated section and a V-shaped section that are interconnected. The guide blocks in the fine washing chamber are all slidably connected in the guide groove two.

[0018] Furthermore, a float valve is fixedly connected to the cleaning tub located in the fine washing chamber at a position away from the rotating shaft. A sealing ring 1 is fixedly connected to multiple float valves. A sealing ring 2 is rotatably connected to the sealing ring 1. The sealing ring 2 is fixedly connected to the second partition above and communicates with the outside of the machine casing through the liquid inlet pipe 1. The cleaning tubs located in the rough washing chamber and the rinsing chamber are respectively connected to the outside of the machine casing through the liquid inlet pipe 2 and the liquid inlet pipe 3.

[0019] Furthermore, the drain assembly includes a drain seat, which is fixedly connected to the bottom of annular seat one and annular seat two. Multiple drain seats are evenly distributed circumferentially on annular seat one and are staggered adjacent to the discharge channel on annular seat one. The drain seats on annular seat two are adjacent to the discharge channel two on it. A liquid collection seat is fixedly connected to the partition below the cleaning tank. The liquid collection seat is an annular container and an annular plate is rotatably connected to its bottom. The discharge channel and discharge channel two are fixedly connected to the corresponding annular plates. The liquid collection seat is connected to the outside of the machine casing through a drain pipe.

[0020] The technical solution provided by this invention has the following advantages compared with the prior art:

[0021] 1. The casing of this invention is divided into a coarse washing chamber, a fine washing chamber, a rinsing chamber and a collection chamber from top to bottom by a partition. Each chamber is distributed around the central rotating axis. The parts are transferred vertically through the feeding channel and feeding trough, without occupying extra space laterally. Compared with traditional horizontal multi-tank cleaning equipment, the vertical design greatly reduces the plane space occupied by the equipment while ensuring the complete cleaning process, and is especially suitable for scenarios with compact production workshop layouts.

[0022] 2. In this invention, after the first batch of parts is cleaned in the coarse washing chamber, the parts are sent to one of the cleaning buckets in the fine washing chamber by rotating the shaft. At the same time, the coarse washing chamber can immediately put in the second batch of parts for coarse washing. In the fine washing chamber, multiple cleaning buckets rotate synchronously with the shaft. While receiving new parts, the previous batch of parts continues to be finely cleaned without waiting for the rinsing chamber to be empty. This parallel operation mode breaks the waiting limitation of the traditional step-by-step operation, solves the efficiency bottleneck caused by the time difference of each link, and makes the coarse washing, fine washing and rinsing processes flow continuously, significantly increasing the parts processing volume per unit time.

[0023] 3. In the coarse washing stage of this invention, the bubble device generates bubbles to drive the cleaning liquid to tumble and remove floating dirt. In the fine washing stage, the ultrasonic cavitation effect is used to penetrate deep holes and gaps in the parts, and the supporting component swings back and forth under the action of the guide groove to avoid parts stacking and blocking. In the rinsing stage, low-power ultrasonic waves are used to assist clean water in rinsing off residual cleaning agents. The graded cleaning is adapted to the treatment needs of different levels of contamination. The dynamic swing adjustment of the fine washing chamber ensures that the ultrasonic energy is transmitted evenly, which solves the problem of cleaning dead corners caused by obstruction of complex structural parts and improves the overall cleaning quality.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] The present invention will be further described below with reference to embodiments.

[0037] Example:

[0038] Please see Figures 1-9 This invention provides a technical solution: a multi-station parallel cleaning tank movable parts cleaning machine, comprising:

[0039] The housing 1 is divided into a coarse washing chamber 12, a fine washing chamber 13, a rinsing chamber 14 and a collection chamber 15 from top to bottom by a partition 11. A rotating shaft 3 driven by a servo motor 2 is fixedly connected to the center of the partition 11. Each of the coarse washing chamber 12, fine washing chamber 13, rinsing chamber 14 and collection chamber 15 is equipped with a cleaning tank 4. A support component 5 is provided in the cleaning tank 4. A cleaning device is connected to the bottom of the cleaning tank 4.

[0040] In the coarse washing chamber 12, the cleaning tub 4 is fixedly connected to the first partition plate 11 above. A ring seat 6 is fixedly connected to the rotating shaft 3 inside the coarse washing chamber 12. The inner wall of the ring seat 6 is provided with a guide groove 61 to guide the rotation of the support component 5 therein. The bottom plate of the ring seat 6 is uniformly connected with a discharge channel 62 along the circumference. The number of discharge channels 62 is the same as the number of cleaning tubs 4 in the fine washing chamber 13. The partition plate 11 located below the discharge channel 62 is provided with a discharge trough 111 corresponding to the discharge channel 62.

[0041] The washing chamber 13 contains multiple cleaning buckets 4, which are fixedly connected to the rotating shaft 3 via a connecting frame. The inner wall of the casing 1 is fixedly connected to an annular seat 7 via a connecting plate within the washing chamber 13. The inner wall of the annular seat 7 has a guide groove 71 that allows the supporting component 5 in the washing chamber 13 to rotate. The cleaning buckets 4 in the coarse washing chamber 12 are located at the starting position. The bottom plate of the annular seat 7 is fixedly connected to a discharge channel 72. A discharge trough 111 corresponding to the discharge channel 72 is also provided on the partition 11 located below the discharge channel 72.

[0042] The rinsing chamber 14 has the same structure as the coarse rinsing chamber 12. Each of the three partitions 11 below is connected to a drain assembly 8. A collection container is provided in the collection chamber 15. The cleaning tanks 4 located in the coarse rinsing chamber 12 and the rinsing chamber 14 are connected to the outside of the casing 1 through the second liquid inlet pipe 45 and the third liquid inlet pipe 46, respectively. A float valve 41 is fixedly connected to the cleaning tank 4 located in the fine rinsing chamber 13 at a position away from the rotating shaft 3. A sealing ring 42 is fixedly connected to multiple float valves 41. A sealing ring 43 is rotatably connected to the sealing ring 42. The sealing ring 43 is fixedly connected to the second partition 11 above and is connected to the outside of the casing 1 through the first liquid inlet pipe 44.

[0043] The drain assembly 8 includes a drain seat 81, which is fixedly connected to the bottom of the annular seat 6 and the annular seat 7. Multiple drain seats 81 are evenly distributed circumferentially on the annular seat 6 and are staggered adjacent to the discharge channel on the annular seat 6. The drain seats 81 on the annular seat 7 are adjacent to the discharge channel 72 on it. A collection seat 82 is fixedly connected to the partition 11 below the cleaning tank 4. The collection seat 82 is an annular container and an annular plate 83 is rotatably connected to its bottom. The discharge channel 62 and the discharge channel 72 are respectively fixedly connected to the corresponding annular plate 83. The collection seat 82 is connected to the outside of the housing 1 through the drain pipe 84.

[0044] Specifically, the cleaning device at the bottom of the cleaning tank 4 inside the rough cleaning chamber 12 is preferably a bubble device. In the initial state, the bottom of the cleaning tank 4 inside the rough cleaning chamber 12 is tightly fitted with the annular seat 6, and its lower end is in a sealed state. The support component 5 is kept horizontal by the guide groove 61. The first batch of parts to be cleaned is put into the cleaning tank 4 of the rough cleaning chamber 12. The parts automatically fall onto the support component 5. The cleaning liquid is introduced into the rough cleaning chamber 12 through the liquid inlet pipe 45. The bubble device delivers compressed air to the bottom of the cleaning tank 4 to form a large number of bubbles. When the bubbles rise, they drive the cleaning liquid to roll, which promotes the efficient removal of floating dirt from the surface of the parts.

[0045] After cleaning is completed, the servo motor 2 drives the rotating shaft 3 to rotate at a specific angle, causing the annular seat 6 of the coarse washing chamber 12 to rotate synchronously, so that the drain seat 81 on the annular seat 6 is connected to the lower end of the cleaning tank 4 of the coarse washing chamber 12. The annular seat 6 stays in this position for a short time, and the wastewater generated during cleaning flows into the collection seat 82 through the drain seat 81 and is then discharged through the drain pipe 84. Subsequently, the rotating shaft 3 continues to rotate at a specific angle, causing the annular seat 6 to align the lower end of the cleaning tank 4 of the coarse washing chamber 12 with the corresponding feeding channel 62 and feeding trough 111. At the same time, a cleaning tank 4 in the fine washing chamber 13 rotates to align with the feeding channel 62, and its lower end is sealed by the bottom of the annular seat 7, and the internal support component 5 remains horizontal.

[0046] After rotation stops, the support assembly 5 rotates to an inclined state under the guidance of the guide groove 61. The parts on the support assembly 5 in the coarse washing chamber 12 fall into the cleaning tank 4 of the fine washing chamber 13 through the corresponding unloading channel 62. At this time, the liquid inlet pipe 44 is connected to the float valve 41. The cleaning liquid enters the cleaning tank 4 at the initial position through the liquid inlet pipe 44. When the liquid level reaches the set height, the float valve 41 closes and the liquid inlet stops. The cleaning device at the bottom of the cleaning tank 4 in the fine washing chamber 13 preferentially adopts an ultrasonic cleaning device. This device utilizes the cavitation effect generated by ultrasound in the cleaning liquid. The energy released when the bubbles burst can penetrate into the deep holes, gaps and threads of the parts and other complex structural parts, effectively removing stubborn dirt.

[0047] After the liquid inlet stops, the rotating shaft 3 continues to rotate at a specific angle and then stops. On the one hand, it drives the annular seat 6 to continue rotating, so that the bottom of the cleaning tank 4 in the coarse washing chamber 12 returns to a closed state. At this time, the second batch of parts is added into it, and the cleaning liquid is introduced again through the liquid inlet pipe 45. After the coarse washing is completed, the coarse washing chamber 12 repeats the above-mentioned liquid discharge and material feeding process as the rotating shaft 3 continues to rotate. At the same time, another cleaning tank 4 in the fine washing chamber 13 moves to align with the upper cleaning tank 4, the material feeding channel 62, and the material feeding trough 111. The second batch of parts in the upper cleaning tank 4 falls into the cleaning tank 4 with the support component 5 tilting. During the movement of the cleaning tank 4 containing the first batch of parts in the fine washing chamber 13, the support component 5 swings back and forth at a small angle under the action of the guide groove 71, continuously adjusting the placement position and angle of the parts, avoiding the parts from stacking and blocking each other, ensuring the effective transmission of ultrasonic energy, and improving the cleaning effect.

[0048] The above process is repeated cyclically, so that the cleaning tank 4 in the fine washing chamber 13 successively receives the parts in the rough washing chamber 12. When the cleaning tank 4 containing the first batch of parts in the fine washing chamber 13 moves to align with the drain seat 81 of the annular seat, it will pause briefly. During this period, the cleaning agent flows through the drain seat 81 into the lower collection seat 82, and then is discharged to the outside of the machine housing 1 through the drain pipe 84. When the rotating shaft 3 rotates again, the cleaning tank 4 moves to align with the discharge channel 72 on the annular seat 7. At this time, the discharge channel 72, the discharge trough 111 of the fine washing chamber 13 and the cleaning tank 4 of the rough washing chamber 12 are aligned. The support component 5 inside the cleaning tank 4 tilts at a large angle under the action of the guide groove, so that the first batch of parts falls onto the support component 5 of the cleaning tank 4 in the rinsing chamber 14.

[0049] At this time, the lower end of the cleaning tank 4 in the rinsing chamber 14 is sealed by the lower annular seat 6. The bottom cleaning device preferentially uses a low-power ultrasonic device to introduce clean water into it through the liquid inlet pipe 46. Combined with ultrasonic rinsing, it removes residual cleaning agent and dirt from the surface and inside of the parts. Then, it stops rotating again with the rotating shaft 3. The same principle as the rough cleaning chamber 12 is followed. The cleaned parts fall into the collection container in the collection chamber 15, and the sewage is discharged from the casing 1 through the corresponding drain pipe 84.

[0050] This process is repeated continuously, allowing the 13 cleaning tanks in the fine cleaning chamber to receive the 12 parts in the rough cleaning chamber in sequence. Multiple sets of fine cleaning work are carried out in parallel, which greatly shortens the waiting time for rough cleaning, significantly extends the overall cleaning cycle, and improves cleaning efficiency.

[0051] The support assembly 5 includes a mounting rod 51, which is arranged radially along the cleaning bucket 4 and rotatably connected to the cleaning bucket 4. A guide rod 52 is slidably connected to the mounting rod 51, and a support plate 53 is fixedly connected to the upper end of the guide rod 52. The support plate 53 has multiple through holes and is connected to the mounting rod 51 through a buffer spring 54.

[0052] The lower end of the support plate 53 is symmetrically fixedly connected with wedges 55, and the mounting rod 51 is symmetrically provided with insertion holes 511 that are adapted to the wedges 55.

[0053] The inner wall of the cleaning bucket 4 is fixedly connected to a locking member 56, and a lock hole 561 is vertically opened on the locking member 56. An arc-shaped locking rod 57 that cooperates with the pin of the lock hole 561 is fixedly connected to the lower end face of the support plate 53.

[0054] The end of the mounting rod 51 away from the central axis of the housing 1 is fixedly connected to a handle 58, and a guide block 59 is fixedly connected to the handle 58.

[0055] The guide channel 61 adopts a closed-loop design. The guide channel 61 is composed of horizontal sections and V-shaped sections that are staggered and interconnected. The number of V-shaped sections is the same as the number of cleaning tubs 4 in the fine washing chamber 13. The guide blocks 59 in the coarse washing chamber 12 and the rinsing chamber 14 are slidably connected in the corresponding guide channel 61.

[0056] The second guide groove 71 adopts a closed-loop design and is composed of a corrugated section and a V-shaped section that are interconnected. The guide blocks 59 in the fine washing chamber 13 are all slidably connected in the second guide groove 71.

[0057] Specifically, in the initial state, in the coarse washing chamber 12, the bottom of the cleaning tub 4 is tightly fitted with the annular seat 6, and its lower end is sealed. In the coarse washing chamber 12, the guide block 59 is located in the horizontal section of the guide groove 61, and the support assembly 5 is kept horizontal due to this restriction. In the fine washing chamber 13, the guide block 59 is located in the horizontal section of the corrugated section of the guide groove 71 at the middle height, so that the mounting rods 51 in each cleaning tub 4 all point upward. Under the elastic tension of the buffer spring 54, each support plate 53 is in a relatively high position in the cleaning tub 4. When the first batch of parts to be cleaned is put into the cleaning tub 4 of the coarse washing chamber 12, the parts fall onto the support plate 53, and the support plate 53 falls down with it. The buffer spring 54 is further compressed to play a buffering role to avoid the parts directly hitting the support plate 53 and causing damage. At the same time, the wedge 55 is precisely inserted into the corresponding insertion hole 511.

[0058] Cleaning fluid is introduced into the coarse cleaning chamber 12 through the inlet pipe 45. The bubbling device delivers compressed air to the bottom of the cleaning tank 4 to form a large number of bubbles. When the bubbles rise, they drive the cleaning fluid to tumble, which promotes the efficient removal of floating dirt from the surface of the parts. After cleaning is completed, the servo motor 2 drives the rotating shaft 3 to rotate at a specific angle. In the coarse cleaning chamber 12, the annular seat 6 rotates with the rotating shaft 3, and the corresponding guide block 59 remains fixed. The two rotate relative to each other, causing the guide block 59 to slide from the horizontal section of the guide groove 61 to the bottom of the V-shaped section.

[0059] This height change drives the handle 58 to rotate, which in turn causes the mounting rod 51 and the support plate 53 to tilt synchronously, causing the parts on the support plate 53 to fall into the fine cleaning chamber 13. During this process, the arc-shaped locking rod 57 is inserted into the locking hole 561 of the locking member 56 and rotates relative to the locking member 56 as the mounting rod 51 rotates: on the one hand, it dynamically adjusts the distance between the support plate 53 and the mounting rod 51 to ensure that the rotation of the support plate 53 is smooth; on the other hand, it locks the support plate 53 during the rotation process to prevent the buffer spring 54 from resetting prematurely after the parts fall, causing the support plate 53 to get stuck in the cleaning bucket 4. After the rotation stops, the support plate 53 in the rough cleaning chamber 12 tilts, causing the parts to fall into the cleaning bucket 4 in the fine cleaning chamber 13 through the unloading channel 62.

[0060] In the fine cleaning chamber 13, the cleaning tank 4 located directly below the cleaning tank 4 in the rough cleaning chamber 12 is connected to the liquid inlet pipe 44 via a float valve 41. The cleaning liquid is injected into the cleaning tank 4. After the liquid level reaches the standard, the float valve 41 is closed. The bottom of the cleaning tank 4 in the fine cleaning chamber 13 preferably has an ultrasonic cleaning device to remove stubborn dirt by utilizing the cavitation effect.

[0061] After the liquid inlet stops, the rotating shaft 3 continues to rotate at a specific angle and then stops. In the fine washing chamber 13, the annular seat 7 remains fixed, and the cleaning bucket 4 carrying the parts rotates relative to the annular seat 7 under the drive of the connecting frame, causing the guide block 59 on it to slide within the corrugated section of the guide groove 71. The height of the guide block 59 changes periodically as it slides, driving the rotating handle 58 to rotate periodically, which in turn causes the mounting rod 51 and the support plate 53 to swing periodically. The swing amplitude is small, which can prevent the parts from falling along the gap between the support plate 53 and the inner wall of the cleaning bucket 4, and can also adjust the position and angle of the parts. When the guide block 59 moves from the corrugated section of the guide groove 71 to the bottom of the V-shaped section, the support plate 53 tilts at a large angle under the drive of the mounting rod 51 and the rotating handle 58, and the cleaning bucket 4 is just aligned with the discharge channel of the annular seat 7, so that the parts fall into the rinsing chamber 14. During this process, the arc-shaped locking rod 57 and the locking piece 56 play the same role as in the rough washing chamber 12, adjusting the spacing and locking the support plate 53.

[0062] The engagement mechanism between the support assembly 5 and the annular seat 6 in the rinsing chamber 14 is the same as that in the coarse rinsing chamber 12: the guide block 59 slides along the guide groove to drive the support plate 53 to tilt, and the parts eventually fall into the collection container in the collection chamber 15. During this process, the arc-shaped locking rod 57 always ensures that the support plate 53 moves accurately, while the buffer spring 54 continuously protects the parts and equipment structure.

[0063] This process is repeated continuously, allowing the 13 cleaning tanks in the fine washing chamber to receive the 12 parts in the rough washing chamber in sequence. Multiple sets of fine washing work are carried out in parallel, which greatly shortens the waiting time for rough washing and significantly improves the cleaning efficiency. The buffer mechanism and dynamic adjustment function further improve the cleaning quality of parts and the service life of the equipment.

[0064] It is worth noting that the above-mentioned multi-station parallel cleaning tank movable parts cleaning machine also has the following advantages:

[0065] Advantage 1: In this embodiment, the casing 1 is divided from top to bottom into a coarse washing chamber 12, a fine washing chamber 13, a rinsing chamber 14, and a collection chamber 15 by a partition 11. Each chamber is distributed around the central rotating shaft 3. The parts are transferred vertically through the feeding channel and the feeding trough 111, without occupying extra space laterally. Compared with traditional horizontal multi-tank cleaning equipment, the vertical design greatly reduces the plane space occupied by the equipment while ensuring the complete cleaning process, which is especially suitable for scenarios with compact production workshop layouts.

[0066] Advantage 2: After the first batch of parts is cleaned in the coarse washing chamber 12, the parts are sent to one of the cleaning buckets 4 in the fine washing chamber 13 by rotating the shaft 3. At the same time, the coarse washing chamber 12 can immediately put in the second batch of parts for coarse washing. Multiple cleaning buckets 4 in the fine washing chamber 13 rotate synchronously with the shaft 3. While receiving new parts, the previous batch of parts continues to undergo fine washing. There is no need to wait for the rinsing chamber 14 to be idle. This parallel operation mode breaks the waiting limitation of the traditional step-by-step operation, solves the efficiency bottleneck caused by the time difference of each link, and makes the coarse washing, fine washing and rinsing processes flow continuously, significantly increasing the parts processing volume per unit time.

[0067] Thirdly, in this embodiment, the coarse washing stage uses a bubbling device to generate bubbles that cause the cleaning liquid to tumble and remove floating dirt. The fine washing stage utilizes the ultrasonic cavitation effect to penetrate deep holes and gaps in the parts, and the supporting component 5 swings back and forth under the action of the guide groove 71 to avoid parts stacking and blocking. The rinsing stage uses low-power ultrasonic waves to assist clean water in rinsing away residual cleaning agents. The graded cleaning adapts to the treatment needs of different levels of contamination. The dynamic swing adjustment of the fine washing chamber 13 ensures that ultrasonic energy is transmitted evenly, solving the problem of cleaning dead corners caused by obstruction of complex structural parts and improving the overall cleaning quality.

[0068] Fourthly, when parts fall onto the support plate 53 inside the cleaning tank 4, the buffer spring 54 is compressed to buffer the impact and prevent damage. When the support assembly 5 tilts to discharge materials, the arc-shaped locking rod 57 and the locking piece 56 work together to lock the position, preventing the buffer spring 54 from resetting prematurely and causing jamming. The precise cooperation between the guide groove 1 61 and the guide groove 2 71 and the corresponding guide block 59 ensures that the switching, drainage and material discharge actions of each cleaning tank 4 are continuous. Multiple mechanical protection mechanisms reduce the hard impact between parts and equipment, while ensuring the stability of the connection between each process, reducing the probability of equipment failure and extending service life.

[0069] Fifthly, in this embodiment, the cleaning chamber 13 automatically controls the cleaning fluid level through the float valve 41. Once the set height is reached, the fluid intake automatically stops. During drainage, the cleaning tank 4 aligns with the drain seat 81, and the wastewater is automatically discharged through the collection seat 82 and the drain pipe 84. No manual operation is required. The automated control reduces manual monitoring and operation, which not only avoids waste of cleaning fluid but also ensures timely drainage without affecting subsequent processes, thus reducing labor costs and operational errors.
