[0025] Figure 1 This is a perspective view of the battery drying device in this utility model; Figure 2 This is a top view of the battery drying device in this utility model; Figure 3 yes Figure 2 Sectional view along the AA direction. See also Figures 1 to 3 The diagram illustrates a preferred embodiment of a battery drying device, comprising a rotating chamber 1, an evaporation chamber 2, a foreign matter collection chamber 3, and an air duct 4. One end of the foreign matter collection chamber 3 is connected to the rotating chamber 1, and the other end is connected to the evaporation chamber 2. An air duct 4 is provided at one end of the evaporation chamber 2. The rotating chamber 1 includes a first chamber body 101, a rotating cage 102, a support, and a rotating motor 105. The support is located inside the first chamber body 101, and the rotating motor 105 is located on the inner side of the support. The rotating cage 102 is located at the upper end of the support, and the output end of the rotating motor 105 is connected to the rotating cage 102. In this embodiment, see [reference needed]. Figure 3As shown, the rotating chamber 1, the evaporating chamber 2, and the foreign matter collection box 3 are interconnected. The evaporating chamber 2 is connected to the air duct 4, which is used to blow airflow into the interior of the evaporating chamber 2 to remove foreign matter (particulate impurities and other residues) from the battery surface, allowing the foreign matter to enter the foreign matter collection box 3. The rotating chamber 1 is used to throw off residual liquid from the battery surface. During use, the rotating motor 105 can drive the rotating cage 102 to rotate, and the rotating cage 102 drives the battery inside to rotate. Under the action of centrifugal force, the residual liquid on the battery surface is thrown off, so that the residual liquid is initially separated from the battery surface. This can reduce the residual liquid on the battery surface, and under the action of the evaporating chamber 2, it can be dried quickly, improving the drying efficiency.

[0026] Furthermore, in a preferred embodiment, the bracket includes a support rod 103 and a support platform 104. The lower end of the support platform 104 is connected to the lower inner wall of the first housing 101 via the support rod 103. The lower end of the support rod 103 is fixedly connected to the lower inner wall of the first housing 101, and the upper end of the support rod 103 is detachably connected to the lower end of the support platform 104 via screws.

[0027] Furthermore, as a preferred embodiment, it also includes an annular slide rail 106 and a slider 107. The annular slide rail 106 is provided at the upper end of the support platform 104, and the slider 107 is provided inside the annular slide rail 106. The lower end of the rotating cage 102 is connected to the slider 107. The annular slide rail 106 is fixedly provided at the upper end of the support platform 104, while the slider 107 is slidably provided inside the annular slide rail 106, which facilitates the stable rotation of the rotating cage 102.

[0028] Furthermore, as a preferred embodiment, a plurality of through holes 108 are provided on the outer peripheral wall of the rotating cage 102. This arrangement facilitates the ejection of residual liquid from the battery surface from the rotating cage 102. A drain port can be provided at the lower end of the first housing 101, through which the ejected residual liquid can be discharged.

[0029] Furthermore, as a preferred embodiment, it also includes a waterproof cover 109, which is disposed on the lower inner wall of the first housing 101, and the rotary motor 105 is disposed inside the waterproof cover 109. See also Figure 3 As shown, the rotary motor 105 is located inside the waterproof cover 109, which can prevent residual liquid in the first housing 101 from entering the rotary motor 105, thus protecting the rotary motor 105. Furthermore, the upper opening of the waterproof cover 109 faces the lower surface of the support platform 104, which can prevent residual liquid that has been thrown out from entering the waterproof cover 109.

[0030] Furthermore, as a preferred embodiment, the foreign object collection box 3 includes a second box body 301, a guide plate 302, and a baffle 303. The second box body 301 has openings at both ends, with one end connected to the first box body 101. Two baffles 303 are provided at one end opening of the second box body 301, forming an opening between the two baffles 303. The guide plate 302 is obliquely arranged at the other end opening of the second box body 301. (See also...) Figure 3 As shown, the two baffles 303 are arranged vertically and are fixedly connected to the inner wall of the second housing 301. The upper surface of the lower baffle 303 is higher than the upper surface of the rotating cage 102 to prevent residual liquid ejected from the rotating cage 102 from entering the second housing 301. The guide plate 302 is fixedly connected to the inner wall of the second housing 301 to facilitate guidance. Particulate residues on the surface of the battery inside the evaporator 2 are blown towards the second housing 301 by the external fan and guided into the second housing 301 by the guide plate 302. Some residues may enter the first housing 101 through the opening. In this case, the first end cap 110 at the top of the first housing 101 can be opened to remove the residues inside the first housing 101. When the external fan blows air into the evaporator 2, the first end cap 110 on the first housing 101 can be opened partially to allow airflow.

[0031] Furthermore, as a preferred embodiment, the evaporator 2 includes a third housing 201 and a battery rack 202. The battery rack 202 is disposed inside the third housing 201. One end of the third housing 201 is connected to the air duct 4, and the other end of the third housing 201 is connected to the other end of the second housing 301. The battery rack 202 is used to place batteries. An external fan is connected to the air duct 4 and blows airflow into the air duct 4. Under the action of the air duct 4, the airflow can blow towards the surface of the battery, thereby blowing away any residue on the battery surface.

[0032] Furthermore, as a preferred embodiment, the battery holder 202 is positioned directly opposite the air duct 4, allowing the airflow to directly act on the surface of the battery. In this embodiment, a motor can be installed at the bottom of the battery holder 202 to drive the battery holder 202 to rotate slowly, thereby causing the battery to rotate slowly, facilitating the airflow to act on the surface of the battery. The surface here does not include the bottom surface of the battery. To blow away residue on the bottom surface of the battery, the battery can be manually flipped over.

[0033] Furthermore, as a preferred embodiment, a first end cap 110 is provided at the upper end of the first housing 101, a second end cap 304 is provided at the upper end of the second housing 301, and a third end cap 203 is provided at the upper end of the third housing 201. The first end cap 110 is detachably connected to the upper end of the first housing 101, the second housing 301 is detachably connected to the second end cap 304, and the third end cap 203 is detachably connected to the third housing 201. The detachment method is not limited to threaded connection, hinge connection, etc.

[0034] In this embodiment, a plurality of vent holes are provided on the first end cap 110. The vent holes can be connected to a gas-liquid separation device, which can be a gas-liquid separator. The residual liquid on the surface of the battery in the third housing 201 and the residual liquid that has evaporated to form a gaseous mixture can be blown into the first housing 101 and the second housing 301 by the action of the fan. The gas enters the gas-liquid separation device through the vent holes and is filtered to filter out part of the residual liquid for recycling. This can realize the recycling of residual liquid (cleaning liquid), save costs, and the residual liquid can be an alcohol / DMC (dimethyl carbonate) cleaning liquid.

[0035] In this embodiment, a heater can be provided on the inner wall of the third housing 201 to provide heat to the inside of the third housing 201, so that the residual liquid on the surface of the battery can evaporate quickly.

[0036] In this embodiment, the rotary motor 105, the heater, and the motor can all be connected to an external PLC controller, and the rotary motor 105, the motor, and the heater can be controlled by the PLC controller.

[0037] The battery drying device in this embodiment can be used for spin-drying and evaporating residual liquid on the battery surface and collecting particulate impurities. Cleaning the battery surface with alcohol / DMC cleaning solution removes foreign matter remaining after electrolyte processing. Existing technologies primarily use laser cleaning to remove foreign matter remaining on the battery surface after electrolyte processing. However, laser cleaning easily generates dust or metal, leading to foreign object defects during inkjet printing, resulting in a production yield below 60%. Simultaneously, laser cleaning damages the pre-plated nickel layer, resulting in poor rust prevention. In this embodiment, however, alcohol / DMC cleaning solution can be used to dry-clean the battery surface, reducing foreign dust and improving the coating yield of subsequent processes. Furthermore, alcohol is volatile, leaving little residue, reducing water waste and lowering costs. It also does not damage the pre-plated nickel layer on the battery surface, providing better rust prevention.

[0038] The existing battery coating process mainly involves battery sealing, laser cleaning, UV inkjet printing, capacity testing, and battery grading. The improved battery coating process involves battery sealing, solvent dry cleaning, UV inkjet printing, capacity testing, and battery grading. The battery drying device in this embodiment is mainly used for the subsequent drying process after the battery has undergone solvent dry cleaning.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
