Description

Technical Field

[0001] This utility model relates to the field of casting cooling technology, and in particular to a casting cooling device for lithium battery separators. Background Technology

[0002] Lithium-ion battery separators are thin-film materials specifically designed for lithium-ion batteries. They are typically made of polyolefin polymers and have a porous structure, primarily serving to separate the positive and negative electrodes. The separator has two main functions: first, to prevent short circuits between the positive and negative electrodes inside the battery; and second, to allow lithium ions to pass freely through its microporous structure, thus ensuring normal charging and discharging. Because its performance directly affects the safety and cycle life of lithium-ion batteries, the requirements for separators are very high, including good mechanical strength, suitable porosity and thickness, and excellent thermal stability and electrolyte wettability. Casting is a crucial step in the lithium-ion battery separator manufacturing process. During production, increasing output or producing thicker films requires cooling the cast sheets. Current cooling devices place the cast sheets inside and cool them using methods such as air cooling or oil cooling. However, the static nature of the cast sheets during cooling results in slow cooling, necessitating improvement. Utility Model Content

[0054] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a casting cooling device for a lithium battery separator.

[0055] A casting cooling device for a lithium battery separator includes a mounting base 1 and a cooling box 2, and a rotating mechanism disposed within the mounting base 1 for rotating the casting.

[0057] refer to Figure 2 and Figure 4 In a preferred embodiment, the fixing part includes: a mounting ring 8, disposed inside the cooling box 2 and fixedly connected to the cooling box 2; a placement seat 9, disposed on the rotating shaft 7 and fixedly connected to the rotating shaft 7; and multiple mounting slots 10, which are disposed on the placement seat 9 for mounting components.

[0058] refer to Figure 4 In a preferred embodiment, the clamping part includes: multiple fixing springs 11 disposed within the mounting groove 10 and fixedly connected to the mounting groove 10; multiple fixing blocks 12 disposed on the fixing springs 11 and fixedly connected to the fixing springs 11; and multiple clamping members 13 disposed on the fixing blocks 12 and fixedly connected to the fixing blocks 12.

[0059] In this configuration, the first pulley 5 and the second pulley 6 are connected by a belt, allowing the first pulley 5 to drive the second pulley 6 to rotate, and the second pulley 6 to drive the rotating shaft 7 to rotate. The mounting ring 8 is mainly used to seal the rotating shaft 7 to prevent oil leakage. When using the fixing spring 11, it is first manually pulled by the fixing block 12 to fix the casting. When fixing the casting, the fixing spring 11 rebounds and squeezes the clamping member 13 to fix it, thus fixing the casting with the clamping member 13.

[0060] refer to Figure 2 In a preferred embodiment, the cooling mechanism includes: a first cooling section disposed on the cooling box 2 for cooling the casting sheet; and a second cooling section disposed on the cooling box 2 for cooling the casting sheet.

[0061] refer to Figure 1 and Figure 2 In a preferred embodiment, the first cooling unit includes: an oil inlet pipe 14, disposed on the cooling tank 2 and fixedly connected to the cooling tank 2; an oil outlet pipe 15, disposed on the cooling tank 2 and fixedly connected to the cooling tank 2; two sliding grooves 16, disposed on the cooling tank 2 for component sliding; and a sliding plate 17, disposed on the sliding grooves 16 and slidably connected to the sliding grooves 16.

[0062] refer to Figure 3 In a preferred embodiment, the second cooling unit includes: a mounting shell 18 disposed on the cooling box 2 and fixedly connected to the cooling box 2; a cross plate 19 disposed inside the mounting shell 18 and fixedly connected to the mounting shell 18; a second motor 20 disposed on the cross plate 19 and fixedly connected to the cross plate 19; a heat insulation layer 21 disposed on the cross plate 19 and fixedly connected to the cross plate 19; and a fan blade 22 disposed on and fixedly connected to the output end of the second motor 20.

[0063] In this configuration, an external cooling circulation device is connected through the oil outlet pipe 15 and the oil inlet pipe 14 to transport cooling oil into the cooling tank 2; the sliding plate 17 can slide in the sliding groove 16 and drive the cooling mechanism to move together; the mounting shell 18 is provided with through holes for heat dissipation; the second motor 20 is used to drive the fan blade 22 to rotate, and the fan blade 22 rotates to cool the cooling tank 2.

[0064] This device, by incorporating a rotating mechanism, allows the castings within the cooling chamber 2 to rotate during oil cooling, accelerating the cooling process. This cooling mechanism enables the use of both oil and air cooling methods for rapid cooling while maintaining the quality of the cooling process.

[0065] Working Principle: When the device is in operation, the sliding plate 17 is pulled open to place the casting sheet to be cooled onto the placement seat 9. The clamping member 13 is then pressed and fixed to the casting sheet by the fixing spring 11 and the fixing block 12. Afterwards, an external circulating cooling device, via the oil inlet pipe 14 and the oil outlet pipe 15, injects oil into the cooling box 2 for cooling. Then, the sliding plate 17 is closed, and the first motor 4, the second motor 20, and the external cooling circulation device are started. After the first motor 4 starts, it drives the first pulley 5 to rotate. The second pulley 6 is driven to rotate via a belt. The rotation of the second pulley 6 drives the rotating shaft 7 to rotate, which in turn drives the placement seat 9 to rotate, causing the casting sheet on the placement seat 9 to rotate, achieving a rapid cooling effect. When the second motor 20 starts, it drives the fan blades 22 to rotate. The rotation of the fan blades 22 carries the heat out of the cooling box 2, achieving a cooling effect. Thus, the casting sheet is cooled using two cooling methods.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
