Description

Technical Field

[0001] This utility model relates to the field of mechanical parts cleaning technology, and in particular to a stepping cleaning machine. Background Technology

[0002] As a critical component in turbochargers, thrust bearings require high cleanliness and thorough cleaning in the final stage of production. Traditional cleaning methods often employ single ultrasonic cleaning, followed by manual transfer to other equipment for spraying, rinsing, or air drying. This approach suffers from fragmented processes, low efficiency, and susceptibility to secondary contamination. Especially in small-batch, multi-batch production scenarios, frequent manual operations make it difficult to guarantee consistent cleaning quality. While some existing automated cleaning equipment exists, most are single-function, lacking multi-process integration and effective isolation between processes, leading to cross-contamination of cleaning solutions and incomplete drying. Therefore, there is an urgent need for a fully automated, step-by-step cleaning system that integrates ultrasonic cleaning, spray cleaning, soaking rinsing, air-drying, and hot-air drying to achieve a highly efficient, clean, and continuous cleaning process.

[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 1-2 As shown, the present invention provides a step-type cleaning machine, which includes five stations arranged sequentially along the traveling direction of the cleaning basket 6: ultrasonic cleaning station 1, spray cleaning station 2, soaking and rinsing station 3, air cutting and drying station 4, and hot air drying station 5.

[0015] The spray cleaning station 2 is equipped with a liftable first isolation door 21 and a second isolation door 22 on both sides. The first isolation door 21 is equipped with a first cylinder 211, and the second isolation door 22 is equipped with a second cylinder 221. The isolation doors close during the spraying process to prevent the cleaning fluid from splashing to other stations, ensuring a clean working environment and reducing cleaning fluid waste.

[0016] The hot air drying station 5 is equipped with a liftable third isolation door 51 and a fourth isolation door 52 on both sides. The third isolation door 51 is equipped with a third cylinder 511, and the fourth isolation door 52 is equipped with a fourth cylinder 521. The isolation doors close during the drying process, forming a relatively enclosed drying space, reducing heat loss and improving drying efficiency.

[0017] Above the ultrasonic cleaning station 1 is a first roller frame lifting cylinder 11, and above the soaking and rinsing station 3 is a second roller frame lifting cylinder 31. These two cylinders control the lifting and lowering of the roller frames at the corresponding stations, allowing the cleaning basket 6 to be immersed in the cleaning liquid tank below for ultrasonic cleaning or soaking cleaning, ensuring that the inner and outer surfaces of the parts are fully in contact with the cleaning liquid.

[0018] The ultrasonic cleaning station 1 and the spray cleaning station 2 are both equipped with a first cleaning liquid tank 12 for collecting and returning the cleaning liquid; the soaking and rinsing station 3 is equipped with a second cleaning liquid tank 32 for collecting the rinsing liquid separately. Since the workpieces in this process have been cleaned in the previous two processes and are relatively clean, a separate second cleaning liquid tank 32 is used to avoid mixing with the cleaning liquid from the previous process; the air cutting and drying station 4 is equipped with a third liquid collection tank 41 for receiving residual droplets blown off during the air cutting process.

[0019] The ultrasonic cleaning station 1 includes a first cleaning fluid circulation unit 13, a large cleaning fluid storage tank 14, and an ultrasonic generator 15. The first cleaning fluid circulation unit 13 includes a first cleaning fluid pump 131 and a first cleaning fluid filter 132. The inlet of the first cleaning fluid pump 131 is connected to the large cleaning fluid storage tank 14, and the outlet of the first cleaning fluid pump 131 is connected to the first cleaning fluid hopper 12 through the first cleaning fluid filter 132. The first cleaning fluid pump 131 draws cleaning fluid from the large cleaning fluid storage tank 14, filters it through the first cleaning fluid filter 132, and then sends it to the first cleaning fluid hopper 12, realizing the recycling of the cleaning fluid and maintaining its cleanliness. The ultrasonic generator 15 is used to generate high-frequency vibrations during the cleaning process to enhance the cleaning effect.

[0020] The spray cleaning station 2 includes a second cleaning fluid circulation unit 23 and a spray nozzle group 24. The second cleaning fluid circulation unit 23 includes a second cleaning fluid pump 231 and a second cleaning fluid filter 232. The inlet of the second cleaning fluid pump 231 is connected to the cleaning fluid storage tank 14, and the outlet of the second cleaning fluid pump 231 is connected to the spray nozzle group 24 through the second cleaning fluid filter 232. The second cleaning fluid pump 231 draws cleaning fluid from the cleaning fluid storage tank 14, filters it through the second cleaning fluid filter 232, and then sends it to the spray nozzle group 24 for high-pressure spray cleaning of the parts, which is especially suitable for cleaning holes and grooves.

[0021] The soaking and rinsing station 3 includes a third cleaning fluid circulation unit 33 and a cleaning fluid storage tank 34. The third cleaning fluid circulation unit 33 includes a third cleaning fluid pump 331 and a third cleaning fluid filter 332. The inlet of the third cleaning fluid pump 331 is connected to the cleaning fluid storage tank 34, and the outlet of the third cleaning fluid pump 331 is connected to the second cleaning fluid hopper 32 through the third cleaning fluid filter 332. The third cleaning fluid pump 331 draws cleaning fluid from the cleaning fluid storage tank 34, filters it through the third cleaning fluid filter 332, and then sends it into the second cleaning fluid hopper 32, ensuring that the cleanliness of the rinsing fluid is higher than that of the previous two stations and avoiding secondary contamination of the parts.

[0022] The air-drying station 4 is equipped with an air pump 42 and an air-drying nozzle 43. The air pump 42 is connected to the air-drying nozzle 43 through a rubber and plastic air duct 44. The air-drying nozzle 43 can move back and forth above the workpiece, blowing off residual liquid droplets on the surface of the part with a high-speed airflow, preparing for subsequent hot air drying.

[0023] The hot air drying station 5 is equipped with a hot air pump 53 and a hot air heater 54. The hot air pump 53 is connected to the hot air heater 54 through an air duct 55. Hot air is blown from below onto the workpieces in the cleaning basket 6, forming a circulating hot air channel to achieve rapid and uniform drying of the parts.

[0024] This invention achieves stepping motion through a conveying unit, which mainly includes a coaxial sprocket assembly 71 driven by a motor 7, a chain 72 arranged around the sprockets, and a cleaning basket drive rod 8 fixed between the chains 72. During operation, the motor rotates according to the PLC control cabinet's instructions, driving the chain 72 to move a fixed pitch via the sprocket assembly 71. The cleaning basket drive rod 8 on the chain 72 moves synchronously, thus pushing the cleaning basket 6 placed on the roller track 9 precisely from one workstation to the next. This conveying method ensures synchronous movement of the cleaning baskets 6 at all workstations, forming an efficient assembly line operation. It achieves stepping conveying of the cleaning baskets 6 and synchronous execution of each process, ensuring full automation from parts feeding to discharging. It is suitable for cleaning precision parts requiring high cleanliness.
