[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] In order to realize the full process automatic cleaning of the shell and other workpieces, in some embodiments of the present invention, reference is made to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the automated cleaning system comprises: The working chamber includes a bottom chamber 11 with an upper opening and a plurality of sub-chambers 12 arranged in sequence along the length direction of the bottom chamber. A feeding port 14 for the workpiece to enter and exit is arranged along the feeding direction of the sub-chamber, so that the workpiece can enter each sub-chamber in sequence for cleaning and other treatments as the processing operation proceeds. Figure 8 and Fig. 9 shown.

[0034] The conveying system 30 is arranged in the bottom bin along the length direction of the bottom bin, and the sub-bins located above the conveying system divide the conveying working surface of the conveying system into multiple stations, including a loading station 201, a steam treatment station 202, a first cleaning station 203, a rinsing station 204, a second cleaning station 205, a hot air drying station 206, an air cooling station 207, and an unloading station 208 arranged in sequence along the conveying direction. The steam treatment station, the first cleaning station, the rinsing station, the second cleaning station, the hot air drying station, and the air cooling station are respectively located in each sub-bin, and the loading station and the unloading station are located outside the sub-bin.

[0035] The setting order of the above-mentioned workstations and the setting of the specific workstations are not unique and can be adjusted according to more practical needs. For example, the setting order of the steam treatment station, the first cleaning station, the rinsing station, the second cleaning station, the hot air drying station, and the air cooling station can be adaptively adjusted as needed; or according to the needs of parts cleaning processing, the setting of one or more of the steam treatment station, the first cleaning station, etc. can be cancelled.

[0036] The steam treatment station, the first cleaning station, the rinsing station, the second cleaning station, the hot air drying station and the air cooling station are respectively provided with a steam treatment unit 21, a first cleaning unit, a rinsing unit, a second cleaning unit, a hot air drying unit and an air cooling unit.

[0037] Among them, the steam treatment unit 21 is used to supply steam to the corresponding sub-compartment, and use steam to treat the oil stains on the surface of the workpiece; the steam treatment unit can adopt an LVR steam treatment machine, which can condense and recover the steam while providing steam to the sub-compartment to reduce the impact of steam on the cleaning process environment.

[0038] The first cleaning unit, the rinsing unit and the second cleaning unit are used to clean the workpiece and to clean the workpiece thoroughly.

[0039] The hot air drying unit is used to send hot air into the corresponding sub-compartment to quickly dry the cleaned workpiece. The hot air drying unit can use a burner 251 to provide a heat source, and send hot air into the corresponding sub-compartment through a heat exchange tube 252, a hot air exchange box 253 and a blower 254 to dry the cleaned workpiece.

[0040] The air cooling unit is used to supply air into the corresponding sub-compartment to dissipate heat and cool the workpiece after hot air drying to facilitate the unloading operation of the workpiece. The air cooling unit can be provided with a plurality of cooling fans 261 on the corresponding sub-compartment, and the cooling fans supply air into the sub-compartment to cool the workpiece after drying.

[0041] The conveying system 30 includes a conveying component and a plurality of loading platforms 31 arranged on the conveying component. The conveying component is used to sequentially convey the workpieces mounted on the loading platform from one station to the next station, and sequentially convey the loading platform after unloading from the unloading station to the loading station.

[0042] The conveying assembly can adopt a structure of a conveying wheel group and two conveying chains arranged on the conveying wheel group, and the two ends of the loading platform are respectively connected to the two conveying chains. In this way, when the driving transmission wheel group rotates, the transmission wheel group drives the conveying chain to move, and the conveying chain drives each loading platform to reciprocate in a circumferential direction.

[0043] The system is equipped with multiple independent sub-compartments, which form separated operating stations in the system, and different processing units are arranged in the sub-compartments. In the process of transporting the workpiece from the loading station to the unloading station, the workpiece is sequentially subjected to steam treatment, cleaning, rinsing, secondary cleaning, hot air drying and air cooling operations, thereby realizing continuous and automatic processing of the workpiece with high cleaning efficiency. Moreover, through the sub-compartment structural design, the steam treatment, cleaning, rinsing, air drying and air cooling operations are respectively completed in independent compartments, which can well guarantee the processing quality of each operation step and improve the quality of workpiece cleaning.

[0044] Through the coordination between the storage and conveying systems, as the work rhythm progresses, the workpieces are conveyed from one station to another. During the intervals between cleaning and other treatments at each station, the workpieces are assembled one by one at the loading station and unloaded one by one at the unloading station, thus achieving continuous and automated processing of large batches of workpieces and improving the cleaning and processing efficiency.

[0045] The loading platform 31 may be provided with a positioning and installation component 311 that cooperates with the workpiece. The positioning and installation component is arranged according to the structure of the workpiece to facilitate the positioning and assembly of the workpiece on the loading platform, to facilitate the installation and removal of the workpiece on the loading platform, and to improve the operation efficiency. Fig.12 As shown, by setting a positioning installation component 311 and utilizing the cooperation between the positioning installation component 311 and the workpiece, the workpiece can be directly assembled on the positioning installation component without performing additional fixing operations on the workpiece, and the workpiece can be stably installed on the loading platform, making the installation and unloading of the workpiece more convenient.

[0046] In some embodiments, the automated cleaning system further comprises a door opening and closing control system; Reference Figure 3 , Figure 5 and Figure 8 , switch doors 13 are respectively arranged on the feeding port, and the switch door control system is used to control the simultaneous opening or closing of each switch door. When the switch doors are opened at the same time, the workpiece can be sent from one sub-bin to the next sub-bin through the feeding port. Switch doors are arranged between the sub-bins to ensure that the workpiece is transmitted between the sub-bins. When the workpiece is cleaned, the switch doors are closed so that good isolation can be formed between the sub-bins, ensuring that the various processing operations will not affect each other, and through the independent chambers formed, the processing effects of steam treatment, air drying, and air cooling operations can be greatly improved, and the quality of workpiece cleaning is improved.

[0047] In some embodiments, the door opening and closing control system includes multiple sets of drive components, transmission mechanisms and drive motors (not shown in the figure); The driving components are respectively arranged at positions corresponding to the respective switch doors, and include two sets of transmission chain components which are arranged opposite to each other in the vertical direction. The transmission chain components include a driving sprocket 41, a driven sprocket 42 and a transmission chain (not shown in the figure). The driving sprockets 41 of the two sets of transmission chain components are arranged at the top of the compartment and connected through a driving shaft 43, and the driven sprockets 42 are arranged opposite to each other at the bottom of the compartment. The transmission mechanism includes a plurality of synchronous gear boxes 44 and a transmission shaft 44 connected to the synchronous gear boxes, and the drive shaft 43 is respectively connected to each synchronous gear box 44; The switch door 13 is slidably connected to the compartment 12 so that the switch door can move in the vertical direction. The switch door is connected to the transmission chains of two sets of transmission chain assemblies at both ends. By controlling the rotation direction of the drive motor, the switch door is driven to open and close simultaneously.

[0048] By controlling the rotation of the drive motor, the drive motor drives the transmission mechanism to move, and the transmission mechanism drives the drive shafts of multiple drive components to rotate at the same time. The drive shaft drives each rotating chain component to move at the same time, and the upper and lower ends of the switch door are respectively connected to the transmission chain, so that the switch door can be driven to open and close at the same time through the movement of the transmission chain. When the workpiece needs to be sent from one station to the next station, the switch door is controlled to open at the same time, and then the conveying assembly is controlled to move so that each loading platform moves the distance of one station, and then the switch door is controlled to close at the same time, and the workpieces on each corresponding station are processed separately.

[0049] In some embodiments, the first cleaning unit, the rinsing unit, and the second cleaning unit include a spray unit 22, which is an annular structure, and a nozzle arranged inwardly thereof is arranged inside the spray unit.

The cleaning pipeline 236 is connected to the water supply system 24.

[0055] In some embodiments, the inner cavity cleaning unit 23 further includes a sensor 237 for detecting the position of the moving platform on the cleaning platform.

[0056] The inner cavity cleaning unit is set on the outside of the sub-bin. After the workpiece is sent to the corresponding workstation, the cleaning motor and the transmission screw drive the mobile platform to move toward the workpiece, so that one end of the cleaning pipeline can extend into the inner cavity of the workpiece, and the water supply system is started to supply water to the cleaning pipeline to clean the inner cavity of the workpiece.

[0057] A sensor 237 is provided on the mobile platform 235.

The locking assembly includes two sets of cylinders 51 arranged opposite to each other. A locking member 52 is arranged at one end of the piston rod of the cylinder 51. Correspondingly, locking grooves 312 are respectively arranged at the positions corresponding to the locking assembly on the loading platform. The locking grooves 312 cooperate with the locking member 52. When the workpiece is sent to the unloading station and the unloading operation is required, the cylinder drives the locking member to move toward the loading platform, so that the locking member is inserted into the locking groove, and the loading platform is locked on the unloading station; after unloading, the locking member is withdrawn from the locking groove to release the lock on the loading platform.

[0060] The automated cleaning system may include an electrical control cabinet 61 and a pneumatic control box 62; the electrical control cabinet 61 is used to control the electrical units and mechanisms such as the steam treatment unit, the first cleaning unit, the rinsing unit, the second cleaning unit, the hot air drying unit, the air cooling unit, and the door opening and closing control system in the system, so as to realize automated control of the electrical units and mechanisms.
