[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0041] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0042] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0044] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0046] As described in the background technology, during medical surgery, medical trays are often used to hold commonly used medical supplies such as medical equipment, disinfectants, and cotton swabs. After using the medical tray, it is necessary to collect the medical tray and clean and sterilize it to prevent cross infection when it is used next time. However, the existing medical trays are usually cleaned manually. Taking the medical tray as a polypropylene tray for holding sterilization solution as an example, in the traditional cleaning process, the polypropylene tray is usually placed under the flow of purified water to connect 2.5L, and then the inner surface of the tray is scrubbed with a clean dust-free cloth. The scrubbing time is not less than 1min, and the total scrubbing is twice. After that, the polypropylene tray is placed under the flow of injection water to connect 2.5L, and the tray is shaken to rinse the inner surface of the tray. 2.5L injection water is replaced again, and the inner surface of the tray is shaken again. After the scrubbing is completed, the tray box is placed on a work surface covered with a dust-free cloth, and the excess water on the inner and outer surfaces of the polypropylene tray is blown dry with a clean air gun. Each time a tray is cleaned, 5L of purified water and 5L of injection water are required, and it takes 5min. It can be seen that the above method of manually cleaning polypropylene pallets is not only time-consuming and labor-intensive, but also wastes a large amount of cleaning fluid, resulting in higher production costs.

[0047] To this end, the present application provides a multi-station cleaning equipment for realizing fully automated cleaning and drying of the objects to be cleaned, so as to reduce the labor intensity of the staff, improve the operating efficiency and save the cleaning fluid.

[0048] The following uses the medical tray, such as a polypropylene tray, as an example to describe the structure of the multi-station cleaning device in the present application. It is understandable that in other embodiments, the multi-station cleaning device in the present application is not limited to being used for cleaning polypropylene trays, but can also be used for cleaning any medical trays, and can also be used for cleaning any parts to be cleaned, which is not limited here.

[0049] See also Figure 1 , Figure 1A schematic diagram of a multi-station cleaning device 10 in an embodiment of the present application is shown. The multi-station cleaning device 10 provided in an embodiment of the present application includes a frame (not shown in the figure), a water tank 100, a cleaning mechanism 200 and a rotating mechanism 300. The frame can be a frame structure formed by splicing multiple profiles, the water tank 100 is arranged in the frame, and has a pre-washing station 101, a fine washing station 102 and a drying station 103. In the embodiment shown in the figure, the fine washing station 102 includes a first fine washing station 102a and a second fine washing station 102b, and the pre-washing station 101, the first fine washing station 102a, the second fine washing station 102b and the drying station 103 are sequentially separated and arranged in a circumferential direction defined by a central axis 20; the cleaning mechanism 200 includes a pre-washing component 210, a fine washing component 220 and a drying component 230 corresponding to the pre-washing station 101, the fine washing station 102 and the drying station 103. In the embodiment shown in the figure, the fine washing component 220 correspondingly includes a first fine washing component 221 and a second fine washing component 222, and the pre-washing component 210, the first fine washing component 221, the second fine washing component 230 222 and the drying component 230 respectively correspond to the pre-wash station 101, the first fine washing station 102a, the second fine washing station 102b and the drying station 103; the rotating mechanism 300 is arranged above the water tank 100, and has four supporting plates 301 for carrying the parts to be cleaned (such as polypropylene trays) in the above-mentioned circumferential direction. The rotating mechanism 300 can rotate around the above-mentioned central axis 20 in a controllable manner so that each supporting plate 301 can pass through the pre-wash station 101, the first fine washing station 102a, the second fine washing station 102b and the drying station 103 in sequence along the above-mentioned circumferential direction, so that the parts to be cleaned can be pre-washed in the pre-wash station 101, the first fine washing station 102a, the second fine washing station 102b, and blow-dried in the drying station 103 in sequence to blow dry the residual cleaning liquid on the parts to be cleaned.

[0050] In this embodiment, the cleaning liquid is flowing clean water, wherein the cleaning liquid used in the pre-cleaning station can be ordinary tap water, the cleaning liquid used in the first fine cleaning station 102a can be purified water after secondary RO (Reverse Osmosis) filtration and EDI (Electrodeionization, also known as continuous electro-desalination technology) treatment, and the cleaning liquid used in the second fine cleaning station 102b can be purified water as raw water, and then high-temperature distillation is performed to obtain injection water with a higher degree of cleanliness.

[0051] It is understandable that in other embodiments, the cleaning liquid may be other types of cleaning liquid. It is also understandable that in other embodiments, the number of times the workpiece to be cleaned is finely washed is not limited to two times, and may be one time or more times, that is, the number of fine washing stations 102 is not limited, and the number of carrier plates 301 in the rotary mechanism 300 is not limited, and may be one, two or more, and the above are not particularly limited.

[0052] Obviously, when there are multiple carrier plates 301, and the number of carrier plates 301 is consistent with the number of workstations in the sink 100, the items to be cleaned on each carrier plate 301 can be cleaned at the same time. For example, when the items to be cleaned on one of the carrier plates 301 are being cleaned for the second time, the items to be cleaned on other carrier plates 301 are being cleaned for the first time, or are being pre-cleaned or blown dry at the same time, so that maximum resource utilization can be achieved, thereby improving work efficiency.

[0053] In order to save cleaning liquid and enable the cleaning liquid to be recycled for multiple times, in one embodiment, the multi-station cleaning equipment 10 also includes a circulating water tank 400, which is arranged below the pre-wash station 101 and is connected to the first fine washing station 102a and the second fine washing station 102b by a pipe, and is also connected to the pre-wash component 210 by a pipe. The purpose of such a configuration is to enable the circulating water tank 400 to collect the cleaning liquid discharged from the first fine washing station 102a and the second fine washing station 102b, so as to provide cleaning liquid when the pre-wash component 210 pre-cleans the parts to be cleaned, so that the cleaning liquid discharged from the first fine washing component 221 and the second fine washing component 222 can be recycled again after the parts to be cleaned are finely washed, so as to provide cleaning liquid for the parts to be cleaned when they are pre-cleaned in the pre-wash station 101 located upstream, without using a new water source, thereby achieving the purpose of saving cleaning liquid.

[0054] Optionally, see Figure 2 In one embodiment, the circulating water tank 400 is also connected to the pre-washing station 101 through a pipeline, so that the cleaning liquid discharged from the pre-washing station 101 can be recycled when the items to be cleaned are pre-washed. Specifically, when the items to be cleaned start to be pre-washed in the pre-washing station 101, the cleaning liquid is discharged from the drain port of the pre-washing station 101 into the circulating water tank 400, and then the pre-washing component 210 extracts the cleaning liquid from the circulating water tank 400 to pre-wash the items to be cleaned again, thereby achieving the purpose of recycling the cleaning liquid discharged from the pre-washing station 101, so as to further save the cleaning liquid.

[0055] See also Figure 3The multi-station cleaning equipment 10 also includes a drainage pump 500. The drainage pump 500 pipeline is connected to the circulating water tank 400. The drainage pump 500 is used to discharge the cleaning liquid in the circulating water tank 400 when the cleaning liquid in the circulating water tank 400 is circulated and reaches a preset standard. This is because when the cleaning liquid in the circulating water tank 400 is circulated and reaches a preset standard, the cleanliness of the cleaning liquid is sharply reduced. In order to ensure that the parts to be cleaned can be cleaned subsequently, it is not appropriate to continue to circulate the cleaning liquid in the circulating water tank 400. Therefore, by setting the drainage pump 500, the waste cleaning liquid that has been recycled for many times can be discharged to avoid using the waste cleaning liquid to clean the parts to be cleaned.

[0056] It is understandable that the preset standard can be the number of times the cleaning liquid is circulated, or the time for which the cleaning liquid is circulated, or the temperature of the cleaning liquid after being circulated for a period of time is lower than a certain temperature, etc., which is not limited here.

[0057] Optionally, there are two circulating water tanks 400. The purpose of setting up two circulating water tanks 400 is that when one of the circulating water tanks 400 provides cleaning liquid for pre-cleaning of the parts to be cleaned, the other circulating water tank 400 can simultaneously collect the cleaning liquid discharged from the fine washing station 102, or when the waste cleaning liquid in one of the circulating water tanks 400 is being discharged, the other circulating water tank 400 can simultaneously collect the cleaning liquid discharged from the fine washing station 102 and provide cleaning liquid for pre-cleaning of the parts to be cleaned, so as to maximize the use of time, make various components work synchronously, avoid idle and waste of resources, and thus improve work efficiency.

[0058] In one embodiment, the pre-wash station 101, the fine washing station 102 (i.e., the outlet where the first fine washing station 102a and the second fine washing station 102b converge), the pre-wash component 210, and the drain pump 500 are respectively connected to the two circulating water tanks 400 through a switching valve 600. The purpose of such a setting is to enable the work performed by the two circulating water tanks 400 to be switched with each other. Specifically, the two circulating water tanks 400 are the first circulating water tank 410 and the second circulating water tank 420, respectively. By connecting the pre-wash station 101 to the first circulating water tank 410 and the second circulating water tank 420 through the switching valve 600, the pre-wash component 210 is connected, so that when the cleaning liquid of the first circulating water tank 410 is used to pre-clean the parts to be cleaned, and the cleaning liquid of the first circulating water tank 410 is exhausted, the cleaning liquid of the second circulating water tank 420 can be used to clean the parts to be cleaned, or when the cleaning liquid of the second circulating water tank 420 is exhausted, it can be switched to using the cleaning liquid of the first circulating water tank 410. The parts to be cleaned are cleaned; in the same way, by setting the fine washing station 102, the pre-washing station 101 and the drainage pump 500, they are connected to the first circulating water tank 410 and the second circulating water tank 420 through the switching valve 600, so that the first circulating water tank 410 or the second circulating water tank 420 can be switched to collect the cleaning liquid discharged from the fine washing station 102, or the first circulating water tank 410 or the second circulating water tank 420 can be switched to collect the cleaning liquid discharged from the pre-washing station 101, or the waste cleaning liquid in the first circulating water tank 410 or the second circulating water tank 420 can be discharged, so as to achieve the purpose of maximizing the utilization of resources.

[0059] Specifically, regarding the structures of the pre-washing assembly 210, the first fine-washing assembly 221, the second fine-washing assembly 222, and the drying assembly 230 in the cleaning mechanism 200, in one embodiment, refer to Figure 4 The pre-wash component 210 includes a first booster pump 211 and a pre-wash nozzle 212. The pre-wash nozzle 212, the first booster pump 211 and the circulating water tank 400 are connected by pipelines in sequence. In this way, negative pressure is generated by the first booster pump 211, and the cleaning liquid in the circulating water tank 400 can be drawn to the pre-wash nozzle 212 through the pipeline, and the pre-wash nozzle 212 can pre-clean the parts to be cleaned.

[0060] The structures of the first fine washing component 221 and the second fine washing component 222 are exactly the same. The first fine washing component 221 includes a second boosting pump A2211, a first fine washing nozzle 2212 and a first cleaning liquid source, and the first fine washing nozzle 2212, the second boosting pump A2211 and the first cleaning liquid source are connected in sequence through pipelines; the second fine washing component 222 includes a second boosting pump B2221, a second fine washing nozzle 2222 and a second cleaning liquid source, and the second fine washing nozzle 2222, the second boosting pump B2221 and the second cleaning liquid source are connected in sequence through pipelines. In this way, negative pressure is generated by the second booster pump A2211, and the cleaning liquid in the first cleaning liquid source can be drawn through the pipeline to the first fine cleaning nozzle 2212, and the first fine cleaning nozzle 2212 can perform the first fine cleaning on the cleaned parts; and negative pressure is generated by the second booster pump B2221, and the cleaning liquid in the second cleaning liquid source can be drawn through the pipeline to the second fine cleaning nozzle 2222, and the second fine cleaning nozzle 2222 can perform the second fine cleaning on the cleaned parts.

[0061] It should be noted that the first cleaning liquid extracted from the first cleaning liquid source in the embodiment of the present application is purified water, and the purified water is used to perform the first fine washing of the parts to be cleaned; the second cleaning liquid extracted from the second cleaning liquid source in the embodiment of the present application is injection water with higher cleanliness, and the injection water is used to perform the second fine washing of the parts to be cleaned.

[0062] As mentioned above, the cleaning liquid used in the second fine washing station 102b in the embodiment of the present application is purified water as the raw water, and then high-temperature distillation is performed to obtain injection water with a higher degree of purity. Therefore, the temperature of the injection water is higher than that of the purified water, and the storage requirement is between 70-100°C. Because the water temperature is also higher than that of purified water, it is about 80°C. If the parts to be cleaned are cleaned at a water temperature of 80°C, a large amount of water vapor will be mixed in the air. Too much water vapor will affect the humidity in the purification workshop. Excessive humidity will cause bacteria to grow in the purification workshop, which is very unfavorable for the cleaning and disinfection and sterilization of the parts to be cleaned.

[0063] Therefore, in the second fine washing component 222, the second booster pump B2221 needs to cool the second washing liquid (i.e., high-temperature injection water) from 80°C to 40°C-50°C before extracting the second washing liquid source to avoid excessive water vapor. Figure 5In one embodiment, the second fine washing component 222 also includes a heat exchange component 2223, and the pipeline of the heat exchange component 2223 is connected to the second booster pump (i.e., the second booster pump A2211) of the first fine washing component 221, and the pipeline is connected to the air source of the drying component 230, so that the second booster pump A2211 can extract the first cleaning liquid (i.e., purified water) from the first cleaning liquid source, and the air source can extract compressed air as a replacement medium to cool the second cleaning liquid (i.e., injection water) extracted by the second booster pump B2221 in the heat exchange component 2223.

[0064] Specifically, the heat exchange component 2223 may include two groups of heat exchangers, one group of heat exchanger pipes is connected to the second booster pump A2211, and the other group of heat exchanger pipes is connected to the air source. Or it can be understood that in other embodiments, the heat exchange component 2223 only includes one group of heat exchangers, and the heat exchanger is simultaneously connected to the second booster pump A2211 and the air source. It can also be understood that the heat exchange component 2223 is only connected to the second booster pump A2211, that is, only the first cleaning liquid is used as the replacement medium for cooling, or only connected to the air source, that is, only compressed air is used as the replacement medium for cooling, and the above are not particularly limited.

[0065] Similarly, please refer to Figure 4 The drying component 230 includes an air source (not shown in the figure) and a drying nozzle 231. The drying nozzle 231 pipeline is connected to the air source. The air source itself can generate negative pressure, so that the compressed air inside itself can be drawn to the drying nozzle 231, and the compressed air is blown out through the drying nozzle 231 to dry the parts to be cleaned after fine washing.

[0066] Please continue reading Figure 5 Since water vapor is inevitably mixed in the compressed air, in order to prevent the mixed water vapor from being blown onto the parts to be cleaned, resulting in the parts to be cleaned not being completely dried, the drying component 230 also includes an exhaust fan 232. The exhaust fan 232 pipeline is connected to the drying station 103, which is used to extract the water vapor blown out by the drying nozzle 231, thereby ensuring that the parts to be cleaned can be completely dried.

[0067] See also Figure 4In order to pre-wash the upper surface and the lower surface of the workpiece to be cleaned at the same time, the pre-wash nozzle 212 includes an upper pre-wash nozzle 212a arranged above the pre-wash station 101 and a lower pre-wash nozzle (not shown in the figure) arranged below the pre-wash station 101. The upper pre-wash nozzle 212a and the lower pre-wash nozzle are respectively connected to the first booster pump 211 through two parallel branch pipes branched from a main pipe, so that when the first booster pump 211 extracts the cleaning liquid from the circulating water tank 400, the cleaning liquid is divided into two paths, one of which reaches the upper pre-wash nozzle 212a, and the other reaches the lower pre-wash nozzle, so that the upper pre-wash nozzle 212a and the lower pre-wash nozzle can pre-wash the upper surface and the lower surface of the workpiece to be cleaned at the same time, without manually turning over the workpiece to be cleaned to pre-wash the upper surface and the lower surface of the workpiece to be cleaned respectively, thereby saving working time and improving working efficiency.

[0068] Similarly, the fine washing nozzle of each fine washing assembly 220 includes an upper fine washing nozzle and a lower fine washing nozzle (not shown in the figure), the upper fine washing nozzle is arranged above the corresponding fine washing station 102, and the lower fine washing nozzle is arranged below the corresponding fine washing station 102. Specifically in the embodiment shown in the figure, the first fine washing nozzle 2212 of the first fine washing assembly 221 includes a first upper fine washing nozzle 2212a and a first lower fine washing nozzle (not shown in the figure), the first upper fine washing nozzle 2212a and the first lower fine washing nozzle are respectively arranged above and below the first fine washing station 102a, so as to simultaneously perform the first fine washing on the upper surface and the lower surface of the to-be-cleaned part; and the second fine washing nozzle 2222 of the second fine washing assembly 222 includes a second upper fine washing nozzle 2222a and a second lower fine washing nozzle (not shown in the figure), the second upper fine washing nozzle 2222a and the second lower fine washing nozzle are respectively arranged above and below the second fine washing station 102b, so as to simultaneously perform the second fine washing on the upper surface and the lower surface of the to-be-cleaned part.

[0069] By the same token, the drying nozzle 231 includes an upper drying nozzle 231a and a lower drying nozzle (not shown in the figure), the upper drying nozzle 231a is arranged above the drying station 103, and the lower drying nozzle is arranged below the drying station 103, so that the upper drying nozzle 231a and the lower drying nozzle can simultaneously dry the upper and lower surfaces of the parts to be cleaned, which will not be elaborated here.

[0070] In order to be able to adjust the cleaning and drying effect according to the height and size of the items to be cleaned, see Figure 6 and Figure 7The multi-station cleaning device 10 further includes a lifting mechanism 700, and the upper pre-wash nozzle 212a, the first upper fine-wash nozzle 2212a, the second upper fine-wash nozzle 2222a and the upper drying nozzle 231a are all connected to the lifting mechanism 700. The lifting mechanism 700 may specifically include an electric cylinder 710 and a lifting plate 720 connected to the output end of the electric cylinder 710. As the electric cylinder 710 is started, the electric cylinder 710 can drive the lifting plate 720 to rise and fall, so that the lifting plate 720 can drive the upper pre-wash nozzle 212a, the first upper fine-wash nozzle 2212a, the second upper fine-wash nozzle 2222a and the upper drying nozzle 231a to rise and fall synchronously. In this way, the cleaning and drying effects can be adjusted by changing the height of the upper pre-wash nozzle 212a, the first upper fine-wash nozzle 2212a, the second upper fine-wash nozzle 2222a and the upper drying nozzle 231a.

[0071] On the basis of the above embodiments, the upper pre-wash nozzle 212a, the first upper fine-wash nozzle 2212a, the second upper fine-wash nozzle 2222a and the upper drying nozzle 231a are also rotatably connected to the lifting mechanism 700, so that the upper pre-wash nozzle 212a, the first upper fine-wash nozzle 2212a, the second upper fine-wash nozzle 2222a and the upper drying nozzle 231a can also be controlled to rotate around an axis parallel to the central axis 20 respectively, so as to expand the range of spraying cleaning liquid or blowing air, thereby further improving the cleaning or drying effect.

[0072] Specifically, the structures of the upper pre-wash nozzle 212a, the first upper fine-wash nozzle 2212a, the second upper fine-wash nozzle 2222a and the upper drying nozzle 231a are exactly the same, see Figure 8 , taking the upper pre-wash nozzle 212a as an example, the upper pre-wash nozzle 212a includes a connecting block 212b and two spray rods 212c, the connecting block 212b is connected to the lifting mechanism 700, the two spray rods are symmetrically arranged along the radial direction of the connecting block 212b, one end of each spray rod 212c is connected to the connecting block 212b, and each spray rod 212c is provided with a plurality of spray holes. It can be understood that the number of spray rods 212c is not limited, and there may be multiple spray rods 212c, the multiple spray rods 212c are arranged at intervals along a circumferential direction, and each spray rod 212c extends along the radial direction of the connecting block 212b, which is not limited here.

[0073] In order to control the spray range of the cleaning liquid and the blowing range of the compressed air, and prevent the cleaning or drying effect from being affected by the spray range or blowing range being too large, please continue to refer to Figure 6 and Figure 7The multi-station cleaning device 10 further includes a plurality of spray hoods 800 connected to the lifting mechanism 700. In the embodiment shown in the figure, there are four spray hoods 800, and the upper pre-wash nozzle 212a, the first upper fine-wash nozzle 2212a, the second upper fine-wash nozzle 2222a and the upper drying nozzle 231a are respectively covered by a corresponding spray hood 800. It can be understood that the number of spray hoods 800 depends on the number of each station, and there is no special limitation here.

[0074] See also Fig. 9 In one embodiment, the multi-station cleaning equipment 10 provided in the present application also includes a loading and unloading mechanism 900, which includes a loading rack 910, a loading channel 920 and a unloading channel 930. The loading rack 910 is spiral-shaped and is connected to the pre-washing station 101 through the loading channel 920. The unloading channel 930 is connected to the drying station 103, so that the parts to be cleaned can flow to the pre-washing station 101 through the loading rack 910 and the loading channel 920, and then pass through the pre-washing station 101, the first fine washing station 102a, the second fine washing station 102b and the drying station 103 in turn. After the pre-washing, first fine washing, second fine washing and drying processes, they are transferred from the drying station 103 to the unloading channel 930 to complete the unloading. In this way, the multi-station cleaning equipment 10 provided in the present application can combine all the actions of loading, pre-washing, fine washing, blowing and unloading, realize automated operation, greatly reduce the labor intensity of personnel, improve operational efficiency, and by setting the loading rack 910 to a spiral shape, it can also save space.

[0075] In one embodiment, the multi-station cleaning device 10 provided in the present application is also built with a control system, which can be a PLC controller. The operator can control the rotation of the rotary mechanism 300, the loading and unloading mechanism 900, and the cleaning time control by programming the PLC controller. Specifically, the control system is in the form of servo plus HMI human-machine control, and parameter visualization control is realized through the HMI human-machine control interface. Manual or automatic control can be realized in the HMI human-machine control interface, and the speed of the lifting structure, the speed and rotation angle of the rotary mechanism 300 can be controlled, which greatly facilitates the operator to operate or debug.

[0076] The following combined Figure 1 , Fig.10 and Fig.11 , the steps of cleaning using the multi-station cleaning device 10 described in the above embodiment are introduced.

[0077] In the first step S1, the water tank 100 is cleaned, and the cleaning liquid discharged from the fine washing station 102 is collected by the circulating water tank 400. Specifically, in this step, the second booster pump A2211 and the second booster pump B2221 are first turned on, the second booster pump A2211 extracts the first cleaning liquid from the first cleaning liquid source to clean the first fine washing station 102a, and the second booster pump B2221 extracts the second cleaning liquid from the second cleaning liquid source to clean the second fine washing station 102b. Meanwhile, during the cleaning process, the circulating water tank 400 (for example, the first circulating water tank 410) collects the cleaning liquid discharged from the first fine washing station 102a and the second fine washing station 102b.

[0078] In the second step S2, after the parts to be cleaned are loaded to the pre-washing station 101, the pre-washing assembly 210 is used to extract cleaning liquid from the circulating water tank 400 in the pre-washing station 101 to pre-clean the parts to be cleaned. The time of each pre-cleaning is controlled to be 10 seconds. In this step, the following steps are specifically included:

[0079] S21, the first circulating water tank 410 is started to supply cleaning liquid, and the cleaning liquid collected by the first circulating water tank 410 is used to pre-clean the parts to be cleaned. At the same time, the cleaning liquid discharged from the first fine washing station 102a and the second fine washing station 102b is collected by the second circulating water tank 420. Since the circulating water tank 400 is connected to the pre-washing station 101 through a pipeline, the cleaning liquid in the first circulating water tank 410 can be circulated multiple times to pre-clean the pre-cleaned parts multiple times.

[0080] S22, when the cleaning liquid in the first circulating water tank 410 has been circulated to a preset standard, the cleanliness of the cleaning liquid is sharply reduced and can no longer be used. At this time, the drainage pump 500 is used to discharge the cleaning liquid in the first circulating water tank 410, and the second circulating water tank 420 is used to continue to collect the cleaning liquid discharged from the first fine washing station 102a and the second fine washing station 102b. At the same time, the switching valve 600 connected to the pre-washing station 101 is used to switch to pre-washing the parts to be cleaned using the cleaning liquid collected in the second circulating water tank 420.

[0081] S23, after the cleaning liquid in the first circulating water tank 410 is emptied, the switching valve 600 connected to the first fine washing station 102a and the second fine washing station 102b is used to switch to using the first circulating water tank 410 to collect the cleaning liquid discharged from the first fine washing station 102a and the second fine washing station 102b, while continuing to use the cleaning liquid collected in the second circulating water tank 420 to pre-clean the parts to be cleaned.

[0082] In this way, by switching the first circulating water tank 410 and the second circulating water tank 420 to alternately provide and collect the cleaning liquid, the purpose of maximizing the use of resources and improving work efficiency can be achieved.

[0083] In the third step S3, the pre-cleaned parts to be cleaned are cleaned at least once by using the fine cleaning assembly 220, and the cleaning liquid discharged from the fine cleaning station 102 is continuously collected by using the circulating water tank 400.

[0084] As described above, in one embodiment, the fine washing station 102 includes a first fine washing station 102a and a second fine washing station 102b, and the fine washing assembly 220 includes a first fine washing assembly 221 and a second fine washing assembly 222, so the parts to be cleaned are finely washed twice, so this step specifically includes the following steps:

[0085] S31, at the first fine washing station 102a, the first fine washing component 221 is used to extract the first cleaning liquid (ie, purified water), and the first cleaning liquid is used to perform the first fine washing on the workpiece to be cleaned, and the time of the first fine washing is controlled to be 10s.

[0086] S32, extract the second cleaning liquid (i.e., injection water) using the second cleaning component 222 at the second fine cleaning station 102b, and use the second cleaning liquid to clean the parts to be cleaned for the second time. In this step, it is optionally necessary to cool the second cleaning liquid, and use the cooled second cleaning liquid to clean the parts to be cleaned for the second time. The reason for cooling has been explained in the previous text and will not be repeated here. Therefore, in step S32, the following steps are also included: S321, extract the first cleaning liquid using the first fine cleaning component 221, and / or extract compressed air using the drying component 230; S322, use the first cleaning liquid and / or compressed air as the replacement medium, and use the heat exchange component 2223 to cool the second cleaning liquid; S323, use the second fine cleaning component 222 to extract the cooled second cleaning liquid to clean the parts to be cleaned for the second time.

[0087] In the fourth step S4 , the workpieces to be cleaned after fine washing are dried by using the drying component 230 at the drying station 103 . The drying time is controlled to be 60 seconds, thereby finally completing the cleaning of the workpieces to be cleaned. The workpieces to be cleaned are then unloaded and are removed from the drying station 103 .

[0088] It can be seen that by using the multi-station cleaning equipment 10 provided in the present application for cleaning, on the one hand, it is possible to combine all the actions of loading, pre-washing, fine washing, blowing and unloading, thereby realizing automated operation, greatly reducing the labor intensity of personnel and improving operating efficiency; on the other hand, by arranging a circulating water tank 400 under the pre-washing station 101, the circulating water tank 400 pipeline is connected to the fine washing station 102 and the pre-washing component 210, so that after the parts to be cleaned are fine washed at the fine washing station 102, the cleaning liquid used for cleaning can enter the circulating water tank 400, and be used to provide cleaning liquid for the pre-washing component 210 when pre-cleaning the parts to be cleaned, thereby achieving the purpose of saving water and reducing production costs.

[0089] Practice has proved that using the multi-station cleaning equipment 10 of the above embodiment to clean polypropylene pallets can save 2.5L of purified water and 2.5L of injection water. Compared with manual cleaning, the water consumption is reduced by 50%; cleaning each pallet can save 3 minutes of labor time and improve work efficiency by 60%.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
