DETAILED DESCRIPTION

[0051] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0052] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0053] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0054] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0055] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0056] Referring to Figure 1 , one embodiment of the present disclosure provides a cleaning system 100 for cleaning the surface of batteries. Generally, when cleaning batteries in the cleaning system 100 , the batteries are placed on a carrier, which circulates within the cleaning system 100 , allowing the cleaning system 100 to sequentially clean and dry the battery surfaces.

[0057] The cleaning system 100 includes a first conveying line 10 and a second conveying line 20 . The first conveying line 10 and the second conveying line 20 are arranged at intervals on a horizontal plane and are both used to convey carriers.

[0058] It should be noted that the horizontal arrangement of the first conveyor line 10 and the second conveyor line 20 means that the first conveyor line 10 and the second conveyor line 20 are offset vertically, that is, the first conveyor line 10 and the second conveyor line 20 are not arranged in an upper and lower layer structure in the vertical direction. At the same time, the heights of the conveying surfaces of the first conveyor line 10 and the second conveyor line 20 for carrying jigs can be the same or different.

[0059] Specifically, the first conveyor line 10 can transport the carriers from the loading station A to the cleaning station B and the rinsing station C in sequence. When the carrier is at the loading station A, batteries can be loaded onto the carrier. When the carrier is at the cleaning station B, the batteries can be cleaned. When the carrier is at the rinsing station C, the batteries can be rinsed. The second conveyor line 20 can transport the carriers from the drying station E to the unloading station F. When the carrier is at the drying station E, the moisture on the surface of the batteries in the carrier can be dried. When the carrier is at the unloading station F, the batteries can be unloaded from the carrier.

[0060] The cleaning system 100 also includes a first transfer robot 30 and a second transfer robot 40. The first transfer robot 30 is used to transfer the carrier from the first conveyor line 10 through the rinsing station C to the second conveyor line 20 to be transported to the drying station E for drying. The second transfer robot 40 can rotate the carrier from the second conveyor line 20 through the unloading station F to the first conveyor line 10 to be transported to the loading station A.

[0061] With the above arrangement, when cleaning batteries, when the carrier is at the loading station A, the batteries are loaded onto the carrier, and the first conveyor line 10 conveys the carrier to the cleaning station B and the rinsing station C. After the batteries are cleaned and rinsed, the first transfer robot 30 transfers the carrier to the second conveyor line 20, which then conveys the carrier to the drying station E. When the carrier is at the drying station E, the batteries are dried, and the second conveyor line 20 conveys the carrier to the unloading station F. After the batteries are unloaded, the second transfer robot 40 transfers the carrier to the first conveyor line 10, which then conveys the carrier to the loading station A for loading, thus starting the next cycle.

[0062] The cleaning system 100 provided in the embodiment of the present disclosure, through the cooperation of the first conveyor line 10, the first transfer robot 30, the second conveyor line 20 and the second transfer robot 40, allows the carrier to flow on the first conveyor line 10 and the second conveyor line 20 arranged at intervals on the horizontal plane. The carrier no longer needs to flow back from the lower structure of the equipment as in the prior art. That is, the cleaning system 100 no longer needs to realize the flow of the carrier through a double-layer structure. The carrier can be circulated directly on the upper part of the conveyor line, so that there is no longer a narrow space at the bottom that is inconvenient to maintain, which brings convenience to the maintenance of the equipment.

[0063] Further, referring to Figure 1, the cleaning system 100 includes a control cabinet 50, and the first conveyor line 10, the second conveyor line 20, the first transfer robot 30 and the second transfer robot 40 are all electrically connected to the control cabinet 50. The control cabinet 50 controls the coordinated operation of the first conveyor line 10, the second conveyor line 20, the first transfer robot 30 and the second transfer robot 40.

[0064] In some embodiments, both the first conveyor line 10 and the second conveyor line 20 utilize a chain and sprocket structure, driven by servo motors, to accurately move the carrier to each workstation. The first transfer robot 30 and the second transfer robot 40 utilize a gear rack and linear slide system to transfer the carrier between the first conveyor line 10 and the second conveyor line 20.

[0065] Of course, it is understandable that in other embodiments, there is no limitation on the structures of the first conveyor line 10, the second conveyor line 20, the first transfer robot 30 and the second transfer robot 40, as long as the purpose of conveying and transferring vehicles can be achieved.

[0066] The first conveyor line 10 and the second conveyor line 20 both extend along a first direction and are arranged at intervals in a second direction intersecting the first direction. The first conveyor line 10 is used to convey the carrier in the forward direction along the first direction, and the second conveyor line 20 is used to convey the carrier in the reverse direction along the first direction. As shown in Figure 1, the forward direction of the first direction is the horizontal left direction in Figure 1, and the reverse direction of the first direction is the horizontal right direction in Figure 1. In some embodiments, the forward direction of the first direction may also be the horizontal right direction in Figure 1, and the reverse direction of the first direction is the horizontal left direction in Figure 1, which is not limited here. The above arrangement allows the carrier to travel along a "mouth"-shaped or "mouth-like" path. The carrier no longer needs to reflux from the lower structure of the equipment as in the prior art. The carrier can be circulated directly on the upper part of the conveyor line, so that there is no longer a narrow space in the lower part that is inconvenient to maintain, which brings convenience to the maintenance of the equipment.

[0067] Furthermore, the first conveyor line 10 and the second conveyor line 20 have the same extension length in the first direction, and are spaced opposite each other in a second direction intersecting the first direction. Specifically, the first direction is perpendicular to the second direction, the first direction is the left-right direction in Figure 1, and the second direction is the up-down direction in Figure 1. The first transfer robot 30 is provided at one end of the first conveyor line 10 and the second conveyor line 20 in the first direction, and the second transfer robot 40 is provided at the other end of the first conveyor line 10 and the second conveyor line 20 in the first direction. In this way, on the one hand, the layout of each structure of the cleaning system 100 is more reasonable, reducing the floor space; on the other hand, when the first conveyor line 10 transports the carrier in the forward direction along the first direction to the end, it is grabbed by the first transfer robot 30, and when the second conveyor line 20 transports the carrier in the reverse direction along the first direction to the end, it is grabbed by the second transfer robot 40, so as to improve work efficiency.

[0068] Of course, in other embodiments, the extension lengths of the first conveying line 10 and the second conveying line 20 may be unequal or slightly different, which is not limited here.

[0069] In some embodiments, referring again to FIG. 1 , the cleaning system 100 further includes a loading device, comprising a first loading robot 61 and a second loading robot 62 . The first loading robot 61 is used to remove and place the cover of the carrier at loading station A, while the second loading robot 62 is used to place the batteries into the carrier. When loading the batteries, the first loading robot 61 removes the cover of the carrier, and the second loading robot 62 places the batteries into the carrier. The first loading robot 61 then lowers the cover to press the batteries down, preventing them from shifting during subsequent operation. In this way, the first loading robot 61 and the second loading robot 62 cooperate to facilitate battery loading.

[0070] The cleaning system 100 has a feeding station H and a rotation and positioning station I. The cleaning system 100 also includes a conveyor 70, which feeds batteries into the feeding station H. The conveyor 70 can transport the batteries from the feeding station H to the rotation and positioning station I. The cleaning system 100 also includes a barcode scanning device 80 and a loading and rejection device 90. The barcode scanning device 80 is used to scan the batteries in the feeding station H, and the loading and rejection device 90 is used to reject batteries that fail the barcode scanning. The second loading robot 62 can grasp the battery in the rotation and positioning station I and rotate the battery through a preset angle for loading onto the carrier.

[0071] With the above arrangement, when the battery arrives at the feeding station H, the barcode scanning device 80 can scan the battery transported by the conveying device 70 one by one. If the battery fails to pass the barcode scanning, it will be rejected by the loading and rejection device 90. The battery that passes the barcode scanning enters the rotation positioning station I, thereby ensuring that the batteries entering the rotation positioning station I are all qualified batteries, and ultimately ensuring that the batteries loaded onto the carrier are all qualified batteries. At the rotation positioning station I, the second loading robot 62 will drive the battery to rotate to a preset angle and load it into the carrier. In one specific embodiment, two rows of batteries can be placed in a carrier, with 8 batteries in each row, for a total of 16. Of course, in other specific embodiments, the number of batteries placed is different due to the different specifications of the carrier, that is, the number of batteries cleaned each time is different, which is not limited here.

[0072] Further, continuing to refer to Figure 1, the conveying device 70 is located on the side of the first conveyor line 10 facing away from the second conveyor line 20, and extends along the second direction. The conveying device 70 includes a first conveying mechanism 71, a transverse docking mechanism 72 and a second conveying mechanism 73. The first conveying mechanism 71 is used to convey the batteries to the feeding station H along the second direction, the transverse docking mechanism 72 is used to receive the batteries conveyed by the first conveying mechanism 71 along the second direction and convey them to the second conveying mechanism 73 along the first direction, and the second conveying mechanism 73 is used to receive the batteries conveyed by the transverse docking mechanism 72 and convey them to the rotation positioning station I along the second direction. In this way, the transverse docking mechanism 72 can achieve docking between the first conveying mechanism 71 and the second conveying mechanism 73, facilitating the transportation of the batteries. Of course, in other embodiments, the first conveying mechanism 71 can also be set to directly convey the batteries to the second conveying mechanism 73 along the second direction, in which case the transverse docking mechanism 72 will be omitted.

[0073] The cleaning system 100 also includes a cleaning device 110 and a rinsing device 120. The cleaning device 110 is used to clean the batteries in the carrier at the cleaning station B, and the rinsing device 120 is used to rinse the batteries in the carrier at the rinsing station C. Specifically, the cleaning device 110 can clean all surfaces of the battery (except the areas that need to be protected during the cleaning process), and uses a cylindrical pipe plus multiple nozzles to clean the surface of the battery, and the cleaning pressure of the nozzle is between 2.5kg and 3kg. The rinsing device 120 can rinse all surfaces of the battery (except the areas that need to be protected during the cleaning process), and uses a cylindrical pipe plus multiple nozzles to rinse the surface of the battery, and the rinsing pressure of the nozzle is between 2kg and 2.15kg.

[0074] Furthermore, the cleaning system 100 also includes a water treatment device 130, which is used to pre-treat the water entering the cleaning device 110. For example, the incoming tap water is filtered through a filter and then softened by a water softener before entering the cleaning water tank and the rinsing water tank. The cleaning system 100 also includes a water circulation device 140, which can circulate the water used to clean or rinse the batteries in the cleaning device 110 and the rinsing device 120 for recycling. For example, a sensor for detecting water quality is provided in the cleaning water tank. When the water quality reaches the minimum set value of the sensor, the cleaning water tank will automatically discharge water to the sewage pipe for treatment.

[0075] In some embodiments, referring again to FIG. 1 , the first conveyor line 10 can transport the carriers from the rinsing station C to the air-shearing station D. The cleaning system 100 further includes an air-shearing device 150, which can blow hot air into the carriers at the air-shearing station D to dry the batteries. The first transfer robot 30 can transfer the carriers passing through the air-shearing station D to the second conveyor line 20. Specifically, the air-shearing device 150 uses compressed air to pass through the slits in the cylindrical air blades to generate a high-speed airflow that removes water from the battery surface, thereby scraping all battery surfaces (except for areas required to be protected during the cleaning process) dry.

[0076] The cleaning system 100 also includes a drying device 160, which is used to dry the batteries in the carrier at the drying station E. Specifically, the drying device 160 uses a fan to generate hot air through a heater and circulates it through a duct to dry moisture from the surface of the batteries on the carrier that enter the cavity. It is contemplated that in other embodiments, the configuration of the drying device 160 is not limited.

[0077] The cleaning system 100 also includes a discharge device, which includes a first discharge robot 171 and a second discharge robot 172. The first discharge robot 171 is used to remove and place the cover plate of a carrier in discharge station F, while the second discharge robot 172 is used to discharge the batteries from the carrier. Specifically, when the carrier is in discharge station F, the first discharge robot 171 removes the cover plate from the carrier, the second discharge robot 172 discharges the batteries, and then the second discharge robot 172 replaces the cover plate. In this way, the first discharge robot 171 and the second discharge robot 172 cooperate to facilitate the discharge of batteries.

[0078] Furthermore, the cleaning system 100 also includes a variable-distance alignment device 180 and an over-temperature detection device 190. The second unloading robot 172 can unload batteries onto the variable-distance alignment device 180, which then adjusts the distance and aligns the batteries. The over-temperature detection device 190 can detect over-temperature conditions on the batteries in the variable-distance alignment device 180, such as by using a temperature sensor to monitor the dried batteries and record any over-temperature conditions.

[0079] The cleaning system 100 further includes a pairing device, which can pair the batteries that have been removed due to over-temperature detection, such as pairing them in pairs or in other numbers.

[0080] In some cases, after a period of use, a carrier requires maintenance. Accordingly, the cleaning system 100 is provided with a maintenance station G, which is located on the side of the second conveyor line 20 facing away from the first conveyor line 10. The second transfer robot 40 is also used to transfer the carrier on the second conveyor line 20 to the maintenance station G for removal and maintenance.

[0081] The cleaning system 100 provided in the embodiment of the present disclosure has the following beneficial effects:

[0082] Under the action of the first conveyor line 10, the first transfer robot 30, the second conveyor line 20 and the second transfer robot 40, the carrier can flow along a "mouth"-shaped path, that is, the cleaning system 100 no longer needs to use a double-layer structure to achieve the flow of the carrier. The carrier can be circulated directly on the upper part of the conveyor line, so there is no longer a narrow space at the bottom that is inconvenient to maintain, which brings convenience to the maintenance of the equipment.

[0083] As the carrier moves along the "mouth"-shaped path, the loading device can automatically load the batteries, the cleaning device 110 and the rinsing device 120 can clean and rinse the batteries, the wind cutting device 150 and the drying device 160 can air-dry and dry the batteries, and the unloading device can automatically unload the batteries. The entire cleaning process of the batteries is completed automatically with a high degree of automation, thereby improving work efficiency.

[0084] The cleaning system 100 is also provided with a maintenance station G, and the second transfer robot 40 can also transfer the carrier on the second conveyor line 20 to the maintenance station G so as to remove the carrier for maintenance.

[0085] Although some specific embodiments of the present disclosure have been described in detail through examples, those skilled in the art will understand that the above examples are for illustration only and are not intended to limit the scope of the present disclosure. Those skilled in the art will understand that the above embodiments may be modified without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
