[0002] As a critical component in turbochargers, the cleanliness of thrust bearings directly impacts equipment performance and lifespan. Traditional cleaning methods often rely on manual operation or step-by-step cleaning equipment, resulting in low cleaning efficiency, significant waste of cleaning fluid, and limited automation. This is especially true for small parts with complex structures and grooves, where conventional cleaning methods struggle to thoroughly remove internal impurities. While ultrasonic cleaning effectively cleans surfaces, its cleaning effect on internal grooves is limited; and although spray cleaning can target grooves, it lacks the overall immersion and vibration cleaning effect. Furthermore, existing equipment often uses separate cleaning units, which occupy a large area and have discontinuous processes, hindering efficient and continuous automated cleaning operations. Therefore, there is an urgent need for an automated cleaning unit that integrates ultrasonic cleaning and spray cleaning, featuring a compact structure and high cleaning efficiency.

[0014] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model: like Figure 1-3 As shown, the present invention provides an ultrasonic cleaning and spray cleaning unit for a step-type automatic cleaning machine, including an ultrasonic cleaning station 1 and a spray cleaning station 2 arranged sequentially along the parts conveying direction, and a transmission mechanism 4 for driving a cleaning basket 3 to move step-by-step between the ultrasonic cleaning station 1 and the spray cleaning station 2. The transmission mechanism 4 includes two parallel annular chains 41, multiple cleaning basket drive rods 42 connected between the two chains 41, and a roller track 43 for supporting the cleaning basket 3. Multiple freely rotatable support rollers 431 are evenly arranged on the roller track 43 to support the cleaning basket 3 and reduce its frictional resistance during movement. The chains 41 are driven by a motor and, through sprocket transmission, drive the cleaning basket drive rods 42 to move intermittently. When the cleaning basket drive rods 42 move to the rear of the cleaning basket 3, they push the cleaning basket 3 forward along the roller track 43 by one station's distance. Then the chains 21 stop, and the cleaning basket 3 performs cleaning operations at the target station. This cycle is repeated to achieve step-by-step conveying.

[0015] The ultrasonic cleaning station 1 includes a liftable upper and lower roller frame 11, upper and lower roller frame cylinders 12 for driving the upper and lower roller frame 11 to rise and fall, an upper and lower roller connecting frame 13 connecting the upper and lower roller frame cylinders 12 and the upper and lower roller frame 11, several upper and lower rollers 14 disposed on the upper and lower roller frame 11, and an ultrasonic generator 15 located below the upper and lower roller frame 11. The ultrasonic cleaning station 1 and the spray cleaning station 2 share a cleaning liquid tank 5. The cleaning liquid tank 5 has a length of 50-100cm, a width of 80-100cm, and a depth of 13-17cm, preferably a length of 55cm, a width of 90cm, and a depth of 15cm. When the cleaning basket 3 moves to the ultrasonic cleaning station 1, the upper and lower roller frame cylinders 12 drive the upper and lower roller frame 11 to descend via the upper and lower roller connecting frame 13, immersing the cleaning basket 3 in the cleaning liquid tank 5. Subsequently, the ultrasonic generator 15 is activated, generating high-frequency vibrations in the cleaning liquid to thoroughly clean the surface and fine structures of the parts. After cleaning, the upper and lower roller frames 11 are raised, causing the cleaning basket 3 to detach from the liquid surface and drain briefly, and then it is moved to the next station by the transfer mechanism 4.

[0016] The cleaning fluid hopper 5 is equipped with a cleaning fluid inlet 51 and a cleaning fluid return inlet 52. The cleaning fluid inlet 51 is used to replenish fresh cleaning fluid or receive recycled filtered cleaning fluid. The distance from the bottom of the cleaning fluid return inlet 52 to the bottom of the cleaning fluid hopper 5 is L, which is 10-14 cm, preferably 12 cm. This facilitates the circulation of the cleaning fluid and the sedimentation of impurities, preventing the pump from drawing in bottom deposits. Sharing a single cleaning fluid hopper 5 between two workstations not only saves space but also enables unified management and recycling of the cleaning fluid, reducing operating costs.

[0017] The ultrasonic cleaning station 1 is also equipped with a first cleaning fluid circulation unit 6 connected to the cleaning fluid tank 5. The first cleaning fluid circulation unit 6 includes a first cleaning fluid pump 61 and a first cleaning fluid filter 62. To achieve efficient circulation and centralized management of the cleaning fluid, the ultrasonic cleaning station 1 and the spray cleaning station 2 are also jointly provided with a cleaning fluid storage tank 7. The cleaning fluid storage tank 7 is located below the first cleaning fluid pump 61 and the first cleaning fluid filter 62. The cleaning fluid storage tank 7 is used to collect the used cleaning fluid that flows back from the cleaning fluid return port 52 of the cleaning fluid tank 5. The first cleaning fluid pump 61 draws the cleaning fluid from the cleaning fluid storage tank 7, and after impurity filtration and purification by the first cleaning fluid filter 62, the clean cleaning fluid is pumped back into the cleaning fluid tank 5, thereby maintaining the cleanliness and flow uniformity of the cleaning fluid, realizing the recycling of the cleaning fluid, and reducing the consumption of cleaning fluid and waste liquid treatment costs.

[0018] The spray cleaning station 2 is located after the ultrasonic cleaning station 1. The spray cleaning station 2 is mainly used for high-pressure rinsing of parts that have undergone preliminary ultrasonic cleaning, and is particularly suitable for cleaning internal pore structures of parts. The spray cleaning station 2 includes multiple sets of cleaning fluid nozzles 21 facing the cleaning basket 3 and a second cleaning fluid circulation unit 22 connected to the cleaning fluid tank 5. The multiple sets of nozzles 21 are mounted on the frame of the spray cleaning station 2 to ensure that the spray range covers all parts within the cleaning basket 3, achieving all-around rinsing. The second cleaning fluid circulation unit 22 includes a second cleaning fluid pump 221 and a second cleaning fluid filter 222. The second cleaning fluid pump 221 also draws cleaning fluid from a shared cleaning fluid storage tank 7, filters it through the second cleaning fluid filter 222, pressurizes it, and distributes it to each set of nozzles 21 through a delivery pipeline, forming a high-pressure spray flow. After spraying, the cleaning solution falls back into the cleaning solution hopper 5, and then flows back to the cleaning solution storage tank 7 through the cleaning solution return port 52, completing the independent circulation and reuse of the sprayed cleaning solution, further ensuring the cleaning effect and resource utilization rate.

[0019] To prevent cleaning fluid from splashing onto adjacent workstations during the spraying process, the spray cleaning station 2 is equipped with a first isolation door 23 and a second isolation door 24, which can be raised and lowered, on both sides. The first isolation door 23 is connected to a first isolation door cylinder 231, and the second isolation door 24 is connected to a second isolation door cylinder 241. When the cleaning basket 3 completes ultrasonic cleaning and is sent into the spray cleaning station 2 by the transmission mechanism 4, and just before the spraying action is about to begin, the first isolation door cylinder 231 and the second isolation door cylinder 241 act simultaneously, driving the first isolation door 23 and the second isolation door 24 to descend, closing the inlet and outlet of the spray chamber, forming a relatively closed spray space. Subsequently, the second cleaning fluid pump 221 starts to perform high-pressure spray cleaning. Therefore, when the first isolation door 23 and the second isolation door 24 are in the descending state, the spray cleaning is in progress. After the spraying process is completed, the second cleaning fluid pump 221 stops, and the first isolation door cylinder 231 and the second isolation door cylinder 241 act again, driving the first isolation door 23 and the second isolation door 24 to rise, opening the passage. At this time, the first isolation door 23 and the second isolation door 24 are in the rising state, indicating that the spraying process has ended, and the cleaning basket 3 can be moved out of the spraying station by the transmission mechanism 4 to enter the next process.

[0020] The cleaning unit also includes a soaking and rinsing station, an air-cutting and drying station, and a hot air drying station, which are arranged sequentially after the spray cleaning station 2 along the conveying direction, thus forming a complete five-station automatic cleaning system. The actions of each station are coordinated by the PLC control cabinet to realize the step-by-step transmission of the cleaning basket 3 and the synchronous operation of each process, completing the fully automated cleaning process from feeding to discharging.

[0021] The operation process of this utility model is as follows: Loading and positioning: The operator loads the parts to be cleaned into the cleaning basket 3, and then places the cleaning basket 3 at the starting end of the transfer mechanism 4 (e.g., the loading position before the ultrasonic cleaning station 1).

[0022] Step-by-step transfer to ultrasonic cleaning station: The control system is activated, and the transfer mechanism 4 smoothly pushes the cleaning basket 3 into the ultrasonic cleaning station 1 along the roller track 43 and accurately positions it.

[0023] Ultrasonic cleaning process: Immersion in cleaning solution: After positioning is completed, the upper and lower cylinders 12 of the roller frame are activated, pushing the upper and lower roller frames 11 to descend, causing the cleaning basket 3 on them to be immersed in the cleaning solution 5.

[0024] Initiation of Ultrasonic Cleaning and Circulation: Ultrasonic generator 15 is activated to perform timed ultrasonic cleaning. Simultaneously, the first cleaning fluid circulation unit 6 is activated to continuously filter and circulate the cleaning fluid.

[0025] Lifting and Drainage: After the preset ultrasonic cleaning time is reached, the ultrasonic generator 15 is turned off, and the upper and lower cylinders 12 of the roller frame move in opposite directions, lifting the upper and lower roller frames 11 and the cleaning basket 3 above the liquid surface for a brief draining.

[0026] Step-by-step transfer to the spray station: The transfer mechanism 4 is restarted, and the cleaning basket 3 is step-by-step transferred from the ultrasonic cleaning station 1 to the spray cleaning station 2.

[0027] Spray cleaning process: Closing the isolation doors: After the cleaning basket 3 is in place at the spray cleaning station 2, the first isolation door cylinder 231 and the second isolation door cylinder 241 are activated, causing the first isolation door 23 and the second isolation door 24 to descend and close the spray area.

[0028] Start the spray: The second cleaning fluid circulation unit 22 is started, and the second cleaning fluid pump 221 pressurizes the filtered cleaning fluid and sprays and rinses the parts in the cleaning basket in all directions and at high pressure through multiple sets of nozzles 21.

[0029] Stop spraying and open doors: After the preset spraying time is reached, the second cleaning fluid pump 221 stops, and the spraying ends. Subsequently, the first isolation door cylinder 231 and the second isolation door cylinder 241 are activated, raising the two isolation doors and opening the passage.

[0030] Transfer to subsequent workstations: The transfer mechanism 4 continues to work, sequentially conveying the cleaning basket 3, which has completed ultrasonic and spray cleaning, to subsequent workstations such as soaking and rinsing, air cutting and drying, and hot air drying, to complete the corresponding processing procedures.

[0031] Unloading: The cleaning basket 3 is finally conveyed to the end unloading position, where the operator takes out the clean and dry parts, completing the entire automated cleaning process.

[0032] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
