Therefore, it should not be construed as a limitation to the present application. The first, second, etc. described are only used to distinguish technical features, and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0037] Combined with Figures 1 - 14 As shown, the battery housing cleaning basket 100 provided by the present invention is particularly applicable to the battery housing cleaning line 1 and is used to realize the batch and rapid cleaning of battery housings. Of course, the battery housing cleaning basket 100 can also be used to hold other product components to realize cleaning.

[0038] Next, first combined with Figures 1 - 6 As shown, in an embodiment of the present invention, the battery housing cleaning basket 100 includes a mother basket 110 and a sub-basket 120. Both the mother basket 110 and the sub-basket 120 are in a hollow structure. Specifically, the mother basket 110 is in an open structure and is used to be fixedly connected to the conveying device, so that the mother basket 110 always runs with the conveying device without disassembly. The sub-basket 120 can be detachably inserted into the mother basket 110 through the opening of the mother basket 110. Therefore, after the sub-basket 120 filled with battery cases to be cleaned is inserted into the mother basket 110, the sub-basket 120 is continuously conveyed to the cleaning device 200 for cleaning through the conveying device and the mother basket 110. The hollow mother basket 110 and sub-basket 120 can ensure that the cleaning liquid enters the interior to realize the cleaning of the battery cases. After cleaning, the sub-basket 120 can be taken out from the mother basket 110. During the whole cleaning process, only the loading and unloading operations of the sub-basket 120 are involved, and the operation steps are few, thereby improving the cleaning efficiency.

[0039] More specifically, the shape and outer diameter of the sub-basket 120 correspond to the shape and inner diameter of the mother-basket 110. In this way, when the sub-basket 120 is installed inside the mother-basket 110, they can cooperate to achieve stable installation, simplifying the overall structure of the cleaning basket 100; moreover, loading the sub-basket 120 into or pulling it out from the opening of the mother-basket 110 is convenient and fast, thereby improving the cleaning efficiency. As for the specific shapes of the mother-basket 110 and the sub-basket 120, no specific limitations are made. In a specific embodiment, both the mother-basket 110 and the sub-basket 120 are of rectangular structure. The rectangular mother-basket 110 is convenient for fixed connection with the conveying device (details will be described later), while the rectangular sub-basket 120 is convenient for the installation of the cylindrical battery case and can maximize the space utilization rate. Of course, according to the different structures of the battery cases to be cleaned, the shapes of the mother-basket 110 and the sub-basket 120 can be set accordingly.

[0040] Refer to the following Figure 2 As shown, in an embodiment of the present invention, the mother-basket 110 includes a bottom wall and four side walls protruding from the bottom wall. Moreover, the bottom wall and the four side walls of the mother-basket 110 are fixedly connected by rods. For example, they can be welded by stainless steel rods. Preferably, rods with corrosion resistance are used to fix the mother-basket 110, so that all the wall surfaces of the mother-basket 110 are of a hollow structure, and the service life of the mother-basket 110 is increased.

[0041] Furthermore, a fixing plate 111 is fixed on the bottom wall of the mother-basket 110. The fixing plate 111 protrudes along the longitudinal direction of the mother-basket 110, and the fixing plate 111 is used to fix the mother-basket 110 to the conveying device. In a specific embodiment, fixing plates 111 are respectively arranged at both ends in the longitudinal direction of the mother-basket 110, and the fixing plates 111 at both ends are symmetrically arranged. The mother-basket 110 is fixed by the symmetrically arranged fixing plates 111 at both ends, so that the stress at both ends of the mother-basket 110 is balanced, and the mother-basket 110 can be effectively prevented from tilting during the process of the conveying device driving the mother-basket 110 to move.

[0042] Combined with the following Figures 2 - 4 As shown, in an embodiment of the present invention, the sub-basket 120 includes a basket body 121 and a basket cover 122 both of which are of hollow structure. The basket body 121 is of a rectangular and open structure. The basket cover 122 is of a rectangular structure and is coverably arranged at the opening of the basket body 121. The outer diameter of the basket cover 122 is greater than or equal to the outer diameter of the opening of the basket body 121. In this way, after the basket cover 122 is arranged on the basket body 121, the opening of the basket body 121 can be closed. In a preferred embodiment, the shape and outer diameter of the basket cover 122 are the same as the shape and outer diameter of the opening of the basket body 121. After the basket cover 122 is arranged on the basket body 121, the edge of the basket cover 122 is substantially flush with the plane where the side wall of the basket body 121 is located, as Figure 3As shown, this can not only ensure the opening of the closed basket body 121, but also avoid the inconvenience during handling and loading / unloading processes caused by the basket cover 122 protruding from the side wall of the basket body 121 on the other hand.

[0043] Continuing to combine Figures 2 - 4 As shown, in a specific embodiment, both the basket body 121 and the basket cover 122 of the sub-basket 120 are formed by fixing rods. For example, they are welded by stainless steel rods, and preferably formed by fixing rods with corrosion-resistant effects. Thus, both of them are in a hollow structure, so that the cleaning liquid can enter the sub-basket 120 to clean the battery case, and the service life of the sub-basket 120 can be extended. Of course, it is not limited to forming the sub-basket 120 by fixing rods, and it is also feasible to make it in a hollow shape through other structural settings.

[0044] Next, combining Figures 4 - 5 As shown, in an embodiment, a plurality of partition frames 1211 are also provided at intervals in the basket body 121, and an accommodation groove 1212 for accommodating the battery case is formed between two adjacent partition frames 1211. More specifically, the partition frames 1211 are formed by rods, and the plurality of partition frames 1211 are arranged at intervals along the longitudinal length direction of the basket body 121, and both ends of each partition frame 1211 are fixed to the side wall and / or bottom wall in the transverse width direction of the basket body 121. The interior of the basket body 121 is divided into a plurality of accommodation grooves 1212 along the longitudinal length direction by the partition frames 1211, as Figure 4 shown. In this specific embodiment, the distance between two adjacent partition frames 1211 is set corresponding to the cylindrical battery case 2 to be cleaned. The cylindrical battery case 2 is loaded into the accommodation groove 1212, and the position of the battery case 2 is restricted by the partition frames 1211, and at the same time, the battery cases 2 are spaced apart from each other, as Figure 5 shown. Thus, it can prevent the battery cases 2 from shifting and stacking during subsequent conveying and cleaning processes, which may affect the cleaning effect; at the same time, it can ensure that the cleaning liquid can contact the battery cases 2 to the greatest extent after entering the basket body 121, thereby avoiding the existence of shielding dead corners that may affect the cleaning effect.

[0045] Combining again Figures 3 - 5 As shown, in an embodiment of the present invention, one side edge of the basket cover 122 is rotatably connected to the basket body 121, and the other side edge of the basket cover 122 is detachably snap-connected to the basket body 121. By rotating the basket cover 122, the basket cover 122 has a first position covering the basket body 121 and a second position pivoting away from the basket body 121. When the basket cover 122 is opened, the battery case 2 to be cleaned can be loaded into the basket body 121 or the cleaned battery case 2 can be unloaded; when the basket cover 122 is closed, it limits the battery case 2 in the basket body 121 to prevent the battery case 2 from detaching during the cleaning process.

[0046] Specifically, at least one pivoting portion 1213 protrudes from one side of the basket body 121 in the transverse width direction. A pivoting hole is formed in the pivoting portion 1213. Correspondingly, a pivoting shaft 1221 is fixed to one side of the basket cover 122 in the transverse width direction. The pivoting shaft 1221 is parallel to the side of the basket cover 122. During installation, the pivoting shaft 1221 is inserted into the pivoting hole to achieve the rotational connection of the basket cover 122. The basket cover 122 can rotate around the pivoting shaft 1221 to cover the basket body 121 or open the opening of the basket body 121. Understandably, the installation positions of the pivoting portion 1213 and the pivoting shaft 1221 can be interchanged, and it is also feasible to achieve the rotational connection of the basket cover 122 through other structures.

[0047] More specifically, a buckle 1222 is provided on the other side of the basket cover 122 in the transverse width direction. The buckle 1222 can be buckled and fixed to the closed basket cover 122 and the basket body 121 to prevent the basket cover 122 from opening during transportation. And, after the buckle 1222 rotates, it can release the basket body 121, so that the basket cover 122 can rotate relative to the basket body 121 to open. The specific structure of the buckle 1222 is not specifically limited in this embodiment. In addition, it is feasible to provide the buckle 1222 on the basket body 121 or on both the basket body 121 and the basket cover 122 at the same time.

[0048] As shown in the following combination with Figures 7 - 14 The present utility model further provides a battery case cleaning line 1, which includes a plurality of battery case cleaning baskets 100, a cleaning device 200, and a conveying line 300. Among them, the cleaning device 200 includes a plurality of cleaning tanks 210, and the cleaning tanks 210 are adjacently arranged in sequence. The cleaning tanks 210 are used to hold cleaning liquid. In the present utility model, the number of the cleaning tanks 210 and the cleaning liquid held in each cleaning tank 210 are not specifically limited and can be flexibly set according to specific cleaning requirements. The conveying line 300 passes through each cleaning tank 210 in sequence and winds around the lower part of each cleaning tank 210 to form a circular structure.

[0049] Combined with Figures 1 - 14As shown, in the utility model, multiple battery shell cleaning baskets 100 include multiple mother baskets 110 and multiple sub-baskets 120 that match each other. Multiple mother baskets 110 are fixed on the conveyor line 300 at intervals. When the conveyor line 300 is running, the mother baskets 110 are driven to run synchronously, so that the mother baskets 110 enter each cleaning tank 210 in turn and leave the cleaning tank 210 at the end of the conveyor line 300. In other words, the mother basket 110 is always fixed on the conveyor line 300 and runs with it. During the cleaning process, there is no need to install and unload the mother basket 110. Each sub-basket 120 can be detachably loaded into the mother basket 110. That is, the sub-basket 120 filled with battery shells 2 is loaded into the mother basket 110, and the mother basket 110 and the sub-baskets 120 therein can be transported to each cleaning tank 210 in turn by the conveyor line 300 to realize automatic cleaning. After the cleaning is completed, the sub-basket 120 can be taken out from the mother basket 110. During the operation of the entire battery shell cleaning line 1, there are only operations of loading the sub-basket 120 into the mother basket 110 and pulling it out of the mother basket 110, which reduces the number of operation steps and thus improves the cleaning efficiency.

[0050] Continue to combine Figures 7 - 11 As shown, in one embodiment of the present invention, the tops of two adjacent cleaning tanks 210 are connected by a connecting portion 220, and a loading end 230 and a unloading end 240 are respectively provided at both ends of the cleaning device 200. Figure 14 As shown, each cleaning tank 210 has a first inclined surface 211 and a second inclined surface 212 arranged opposite to each other in the conveying direction of the conveyor line 300, and the first inclined surface 211 and the second inclined surface 212 extend obliquely downward from the connecting portion 220 to the middle of the cleaning tank 210. The conveyor line 300 is arranged to fit the first inclined surface 211, the second inclined surface 212 and the connecting portion 220. As a result, when the conveyor line 300 transports the mother basket 110, the mother basket 110 moves along the first inclined surface 211 and the second inclined surface 212 with a certain slope, which can prevent the sub-basket 120 in the mother basket 110 from flipping out of the mother basket 110 due to a large inclination angle. Moreover, on the cleaning line 1, there are only operations of loading and unloading the sub-basket 120 into and from the mother basket 110, and the operation steps are few and convenient, thereby greatly improving the cleaning efficiency.

[0051] Continue to combine Figures 7 - 12 As shown, in a specific embodiment, the cleaning device 200 includes a first side wall 250, a second side wall 260 and a bottom wall 270 connected therebetween. The bottom wall 270 is undulating, and is surrounded by the first side wall 250, the second side wall 260 and the bottom wall 270 to form a plurality of cleaning tanks 210 that are adjacent to each other in sequence. More specifically, the bottom wall 270 is generally wavy, such as Figure 10As shown in the figure. The conveyor line 300 is disposed on the upper surface of the undulating bottom wall 270, and the conveyor line 300 is wound around the lower side of the bottom wall 270 and connected end to end to form a loop. The operation of the conveyor line 300 drives the mother basket 110 to move along the bottom wall 270, thereby driving the sub-baskets 120 in the mother basket 110 to successively immerse into each cleaning tank 210 for cleaning. Then, the sub-baskets 120 are taken out from the mother basket 110 at the discharging end 240 to complete the cleaning, improving the cleaning efficiency.

[0052] In this embodiment, a bracket is further disposed under the bottom wall 270 to support the entire cleaning device 200. The structure of the bracket is a conventional structure in the art and will not be described in detail.

[0053] Next, in conjunction with Figures 8 - 9 , Figures 11 - 13 As shown in the figure, in a specific embodiment, the loading end 230 and the discharging end 240 may be directly formed by the convex portions of the bottom wall 270, or may be in a hollow shape but with the position of the conveyor line 300 being at the same height as the above-mentioned connecting portion 220. In this way, at both the loading end 230 and the discharging end 240, it is ensured that the mother basket 110 on the conveyor line 300 is separated from the liquid level of the cleaning tank 210, facilitating the loading of the sub-basket 120 into the mother basket 110 and the removal of the sub-basket 120 from the mother basket 110.

[0054] Next, in conjunction with Figure 7 , Figures 11 - 13 As shown in the figure, in a specific embodiment of the present invention, the conveyor line 300 includes a driver (not shown in the figure), a rotating shaft 310, a sprocket 320, and a chain 330. Among them, two rotating shafts 310 are installed at both ends of the cleaning device 200, specifically installed at the tops of the first side wall 250 and the second side wall 260, and at least one rotating shaft 310 is connected to the driver. The sprocket 320 is installed on the rotating shaft 310, and the chain 330 is wound around the sprocket 320 and is wound around the upper and lower sides of the bottom wall 270 to form a loop. In this specific embodiment, there are two chains 330, and the two chains 330 are respectively wound around both ends of the rotating shaft 310, and the distance between the two chains 330 corresponds to the length of the fixing plates 111 at both ends in the longitudinal direction of the mother basket 110. Each mother basket 110 is fixed to the two chains 330 through the fixing plates 111 at both ends thereof, thereby enabling the mother basket 110 to be in a balanced force state and preventing the mother basket 110 from tilting due to uneven force during the movement driven by the chain 330.

[0055] Next, once again in conjunction with Figures 1 - 14 As shown in the figure, the working principle and process of the battery housing cleaning line 1 of the present invention will be described.

[0056] As Figure 5As shown, before cleaning, first place the battery case 2 into the sub-basket 120. That is, snap the battery case 2 one by one into the receiving slots 1212 in the sub-basket 120, and use the partition frame 1211 to hold and restrict the position of the battery case 2. After filling, cover the basket lid 122 on the basket body 121, and fasten the buckle 1222 to fix the basket lid 122 and the basket body 121.

[0057] As Figure 7 , Figure 10 shown, when the battery housing cleaning line 1 is operating, the drive of the conveyor line 300 drives the chain 330 to run, and the chain 330 drives the mother basket 110 fixed thereto to run synchronously.

[0058] Refer to Figures 7 - 14 shown, at the loading end 230, place the sub-baskets 120 filled with battery cases 2 one by one into the mother basket 110, and the chain 330 drives the mother basket 110 and the sub-baskets 120 therein to move and sequentially pass through each cleaning tank 210, so that the mother basket 110 and the sub-baskets 120 are both immersed below the liquid level of the cleaning tank 210 to achieve the cleaning of the battery cases, as Figure 14 shown. When the sub-basket 120 is conveyed to the unloading end 240, take out the sub-basket 120 from the mother basket 110 to complete the cleaning.

[0059] Combined with Figure 14 shown, since the cleaning tank 210 has a first inclined surface 211 and a second inclined surface 212 in the conveying direction, the chain 330 drives the mother basket 110 to enter the cleaning tank 210 along the first inclined surface 211, and then move out of the cleaning tank 210 along the second inclined surface 212. The mother basket 110 has a certain inclination angle. Therefore, the sub-basket 120 in the mother basket 110 will not turn out due to a large inclination angle; moreover, directly load or pull out the sub-basket 120 from the opening of the mother basket 110 makes the operation of loading and unloading the sub-basket 120 simpler and can effectively improve the cleaning efficiency.

After cleaning, take out the sub-basket 120 from the mother basket 110. There are only operations of loading the sub-basket 120 into the mother basket 110 and taking out the sub-basket 120 from the mother basket 110 on the entire cleaning line, and the operation steps are greatly reduced, thereby improving the cleaning efficiency.

[0061] Correspondingly, the battery case cleaning line 1 with the battery case cleaning basket 100 of the present utility model is provided with a conveying line 300 that sequentially passes through a plurality of cleaning tanks 210 and is connected end to end to form a ring structure, and a plurality of mother baskets 110 are fixedly arranged at intervals on the conveying line 300. When the conveying line 300 operates, it drives each mother basket 110 to move synchronously. Therefore, during cleaning, it is only necessary to load the sub-basket 120 filled with battery cases 2 into the mother basket 110 at one end of the conveying line 300, and the conveying line 300 drives the mother basket 110 and the sub-basket 120 to sequentially pass through each cleaning tank 210 to achieve automatic cleaning, and then take out the cleaned sub-basket 120 from the mother basket 110 at the other end of the conveying line 300. The conveying line 300 operates in a cycle and continuously sends the mother basket 110 and the sub-basket 120 into each cleaning tank 210 for cleaning, realizing large-batch automatic cleaning with a high degree of automation; moreover, in the entire battery case cleaning line 1, it is only necessary to load the sub-basket 120 into the mother basket 110 and take it out from the mother basket 110, and the operation steps are greatly reduced, thereby greatly improving the cleaning efficiency.
