[0028] Please refer to Figures 1 to 4 The lithium ion battery cleaning and drying device in the first embodiment of the present application comprises a cleaning box 1, a transfer assembly 3 for loading lithium ion batteries 2, a conveying mechanism 4 and a drying mechanism 6. The cleaning box 1 is internally provided with cleaning liquid. The transfer assembly 3 is placed on the conveying mechanism 4, the conveying mechanism 4 is installed in the cleaning box 1, the transfer assembly 3 is conveyed through the cleaning liquid in the cleaning box 1 and then conveyed to the drying mechanism 6. The drying mechanism 6 is installed above the cleaning box 1 to dry the lithium ion batteries 2 that have passed through the cleaning liquid. The transfer assembly 3 comprises a bearing member 31 and a transition member 32. The transition member 32 is installed on both sides of the bearing member 31. The bearing member 31 is placed on the conveying mechanism 4. The bearing member 31 is provided with a plurality of storage gaps 33 for supporting the lithium ion batteries 2 and leaking the cleaning liquid. The bearing member 31 is wrapped with an insulating layer.

[0029] The plurality of lithium ion batteries 2 are placed on the conveying mechanism 4, and then the conveying mechanism 4 is started to move the plurality of lithium ion batteries 2 to the rear end. The conveying mechanism 4 drives the plurality of lithium ion batteries 2 to pass through the cleaning liquid in the cleaning box 1, and the surface of the plurality of lithium ion batteries 2 is cleaned by the cleaning liquid. The plurality of storage gaps 33 are arranged on the carrier 31, which can separate the lithium ion batteries 2 and make the cleaning liquid fully contact with the surface of each lithium ion battery 2, so as to prevent the lithium ion batteries 2 from being adhered to each other, improve the cleaning efficiency, and clean more thoroughly. The cleaning liquid can also leak out of the storage gap 33, which prevents the cleaning liquid from being taken out of the cleaning box 1, reduces the waste of the cleaning liquid, and protects the surrounding environment.

[0030] The plurality of lithium ion batteries 2 are placed on the conveying mechanism 4, and then the conveying mechanism 4 is started to move the plurality of lithium ion batteries 2 to the rear end. The conveying mechanism 4 drives the plurality of lithium ion batteries 2 to pass through the cleaning liquid in the cleaning box 1, and the surface of the plurality of lithium ion batteries 2 is cleaned by the cleaning liquid. The plurality of storage gaps 33 are arranged on the carrier 31, which can separate the lithium ion batteries 2 and make the cleaning liquid fully contact with the surface of each lithium ion battery 2, so as to prevent the lithium ion batteries 2 from being adhered to each other, improve the cleaning efficiency, and clean more thoroughly. The cleaning liquid can also leak out of the storage gap 33, which prevents the cleaning liquid from being taken out of the cleaning box 1, reduces the waste of the cleaning liquid, and protects the surrounding environment. The plurality of lithium ion batteries 2 are placed on the conveying mechanism 4, and then the conveying mechanism 4 is started to move the plurality of lithium ion batteries 2 to the rear end. The conveying mechanism 4 drives the plurality of lithium ion batteries 2 to pass through the cleaning liquid in the cleaning box 1, and the surface of the plurality of lithium ion batteries 2 is cleaned by the cleaning liquid. The plurality of storage gaps 33 are arranged on the carrier 31, which can separate the lithium ion batteries 2 and make the cleaning liquid fully contact with the surface of each lithium ion battery 2, so as to prevent the lithium ion batteries 2 from being adhered to each other, improve the cleaning efficiency, and clean more thoroughly. The cleaning liquid can also leak out of the storage gap 33, which prevents the cleaning liquid from being taken out of the cleaning box 1, reduces the waste of the cleaning liquid, and protects the surrounding environment.

[0031] The insulating layer wrapped around the carrier 31 can buffer the collision between the lithium-ion battery 2 and the carrier 31, reduce the wear of the lithium-ion battery 2 during cleaning and drying, and thus reduce the loss of the lithium-ion battery 2. The insulating layer can also prevent short circuits between the lithium-ion batteries 2 through the carrier 31, further reducing the occurrence of short circuits between the lithium-ion batteries 2, and further improving the yield and safety.

[0032] Please see Figures 1 to 4 In some embodiments, the lithium-ion battery 2 is inserted at an angle into the storage gap 33.

[0033] This application involves tilting the lithium-ion battery 2 into the storage gap 33. This tilting of the lithium-ion battery 2 into the storage gap 33 tilts the bottom surface of the lithium-ion battery 2, allowing residual moisture on the surface of the lithium-ion battery 2 to flow down more quickly along the tilt angle, thereby reducing residual moisture on the surface of the lithium-ion battery 2, improving the drying efficiency of the lithium-ion battery 2, and reducing the occurrence of short circuits.

[0034] This allows operators to more easily and conveniently tilt and insert the lithium-ion battery 2 into the storage gap 33, reducing labor intensity, improving the stability of the lithium-ion battery 2 placed on the support 31, thereby improving safety and facilitating transportation.

[0035] Please see Figures 1 to 4 In some embodiments, the support member 31 includes a frame 311, spacers 312 and stops 313. Multiple spacers 312 are mounted on the frame 311, and multiple stops 313 are mounted on the frame 311 in a wave-like arrangement perpendicular to the spacers 312.

[0036] This application uses multiple spacer bars 312 mounted on a frame 311, and multiple baffle bars 313 arranged in a wave-like pattern perpendicular to the spacer bars 312 mounted on the frame 311. The multiple spacer bars 312 and multiple baffle bars 313 are perpendicular to each other, forming a storage gap 33. The lithium-ion battery 2 is placed within the storage gap 33. Because the cross-sections of the spacer bars 312 and baffle bars 313 are circular, the contact area between the spacer bars 312 and baffle bars 313 and the lithium-ion battery 2 is small, further reducing moisture residue between the lithium-ion battery 2 and the spacer bars 312 and baffle bars 313, thus further improving the efficiency of cleaning and drying.

[0037] The baffles 313 arranged in a wave pattern on the frame 311 have a storage gap 33 located in the concave part of the wave pattern, making the upper and lower parts of the storage gap 33 conical. This makes it easier for operators to place the lithium-ion battery 2 into the storage gap 33, reducing labor intensity and improving placement efficiency. The distance between the two baffles 313 on the same horizontal plane of the storage gap 33 decreases as it goes down, making it suitable for placing different models of lithium-ion batteries 2 into the storage gap 33, expanding the range of applications and making cleaning and drying more versatile.

[0038] Please see Figures 1 to 4 In some embodiments, the transition member 32 includes a grip 321 and a guide rod 322, the grip 321 being mounted on the frame 311 and the guide rod 322 being obliquely mounted between the grip 321 and the frame 311.

[0039] This application utilizes a gripping frame 321 mounted on a frame 311, with a guide rod 322 obliquely mounted between the gripping frame 321 and the frame 311. The gripping frame 321 allows operators to move the transfer component 3 more easily and effortlessly, improving transfer efficiency and ensuring greater stability during transport. The guide rod 322, obliquely mounted between the gripping frame 321 and the frame 311, allows the transfer component 3 to pass more smoothly through the connection nodes of the conveying mechanism 4, reducing shaking when the transfer component 3 carries multiple lithium-ion batteries 2 through the cleaning and drying mechanism 6, further reducing collisions between the lithium-ion batteries 2, and improving yield and safety.

[0040] Please see Figures 1 to 5 In some embodiments, the conveying mechanism 4 includes a cleaning section 41 and a draining section 42, both of which are installed in the cleaning box 1, with the draining section 42 being higher than the cleaning section 41, and the cleaning section 41 being located in front of the draining section 42.

[0041] In this application, both the cleaning section 41 and the draining section 42 are installed in the cleaning tank 1, with the draining section 42 being higher than the cleaning section 41. The cleaning section 41 is located in front of the draining section 42. The draining section 42 is located below the drying mechanism 6. After the transfer component 3 moves onto the draining section 42, it can continue to drain, further preventing the cleaning fluid from being carried out of the cleaning tank 1, thereby reducing the waste of cleaning fluid, saving cleaning costs, and protecting the surrounding working environment.

[0042] Please see Figures 1 to 5 In some embodiments, the drain section 42 includes a drive roller 421, a driven roller 422, and a conveyor belt 423. The drive roller 421 and the driven roller 422 are rotatably connected to the washing tank 1, and the conveyor belt 423 is wound between the drive roller 421 and the driven roller 422.

[0043] In this application, both the drive roller 421 and the driven roller 422 are rotatably connected to the cleaning tank 1. The conveyor belt 423 is wound between the drive roller 421 and the driven roller 422. The drive roller 421 is connected to a motor, which drives the drive roller 421 to rotate clockwise. The friction between the drive roller 421 and the conveyor belt 423 causes the conveyor belt 423 to move towards the rear end. The conveyor belt 423 then drives the transfer assembly 3 to pass under the drying mechanism 6. The transfer assembly 3 carries multiple lithium-ion batteries 2 and moves towards the rear end while drying them, thereby improving efficiency. During the movement of the lithium-ion batteries 2 towards the rear end, the hot air blown by the drying mechanism 6 will act on different positions of the same lithium-ion battery 2, thereby drying each position of the lithium-ion battery 2 and reducing the occurrence of short circuits.

[0044] Please see Figures 1 to 5 In some embodiments, the cleaning section 41 is V-shaped and includes a lower moving end 411 and an upper moving end 412. Both the lower moving end 411 and the upper moving end 412 are mounted on the cleaning box 1, and the point where they meet is the lowest position. The lower moving end 411, the upper moving end 412 and the draining section 42 all adopt the same structure.

[0045] In this application, both the cleaning section 41 and the draining section 42 are installed on the cleaning tank 1. The cleaning section 41 is located in front of the draining section 42 and is V-shaped. The V-shaped cleaning section 41 can drive the transfer component 3 to enter the cleaning solution stably. The surface of the lithium-ion battery 2 is immersed and cleaned by the cleaning solution. As the transfer component 3 moves to the rear end with the conveying mechanism 4, the V-shaped cleaning section 41 will drive the transfer component 3 to leave the cleaning solution. When the transfer component 3 rises, it is tilted as a whole, which can guide the residual water, reduce the cleaning solution residue on the transfer component 3 and the lithium-ion battery 2, reduce the drying pressure, and improve the drying efficiency.

[0046] This application utilizes a lower end 411 and an upper end 412 both mounted on the cleaning tank 1, with their junction at the lowest point. This lowest-position junction allows the transfer assembly 3 carrying lithium-ion batteries 2 to be fully immersed in the cleaning fluid, reducing the amount of cleaning fluid used and avoiding waste, thereby improving cleaning cost savings. The lower end 411, upper end 412, and drain section 42 all employ the same structure. This identical structure facilitates manufacturing, allows for standardized replacement of parts during maintenance, and enables standardized installation. The V-shaped arrangement of the lower end 411 and upper end 412 allows the transfer assembly 3, carrying multiple lithium-ion batteries 2, to slowly enter or leave the cleaning fluid, improving cleaning stability and further reducing lithium-ion battery wear.

[0047] Please see Figures 1 to 6 In some embodiments, the drying mechanism 6 includes a drying rack 61 and a dryer 62. The drying rack 61 is mounted on the cleaning tank 1, and the dryer 62 is mounted on the drying rack 61. The drying air is directed towards the conveying mechanism 4.

[0048] This application utilizes a drying rack 61 mounted on the cleaning tank 1, with a dryer 62 mounted on the drying rack 61, and the drying airflow directed towards the conveying mechanism 4. The drying rack 61 can shield the left and right sides of the drain section 42 of the conveying mechanism 4, reducing heat loss during drying and allowing more heat to remain within the drying rack 61 for drying the lithium-ion battery 2, thereby improving drying efficiency and saving energy. The drying rack 61, by shielding the left and right sides of the drain section 42, also prevents the cleaning liquid on the surface of the lithium-ion battery 2 from being blown out of the cleaning tank 1 during drying, further protecting the surrounding environment. The dryer 62, mounted on the drying rack 61 with its air outlet facing downwards, blows the cleaning liquid on the surface of the lithium-ion battery 2 downwards when the dryer 62 is started, further preventing splashing of the cleaning liquid, protecting the surrounding environment, and reducing labor intensity.

[0049] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
