Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to an ultra-thin arc-shaped stress-free lithium battery packaging component. Background Technology

[0002] The stress-free packaging structure for ultra-thin curved lithium batteries typically consists of curved end caps that match the curvature of the battery. During packaging, the curved grooves of the end caps engage with the edges of the battery cell to create a curved seal. Combined with specific packaging materials and processes, this ensures uniform stress distribution on the battery cell during packaging, preventing stress buildup, ensuring packaging quality, and reducing risks such as leakage.

[0003] The ultra-thin curved lithium battery stress-free encapsulation component is designed for ultra-thin curved lithium batteries, aiming to reduce encapsulation stress and improve battery performance and reliability. It is mainly used in smart wearable devices, such as smartwatches, bracelets, and smart clothing, where it can better conform to the curves of the human body and improve wearing comfort. It is also suitable for flexible display devices, providing power support while adapting to bending, folding, and other shape changes of the device. Furthermore, it can be used in implantable medical devices to meet their needs for miniaturized, curved battery structures, and its high safety helps protect human health.

[0004] In the existing technology, the stress-free packaging component for ultra-thin arc-shaped lithium batteries still has a large stress during packaging, which may affect the use of the battery. Packaging requires a lot of manual assembly line operation. Using traditional planar packaging devices and then bending the battery can easily damage the cell and affect the electrical performance. It may also produce wrinkles that affect the appearance. In the case of ultra-thinness, conventional aluminum-plastic film punching technology is not applicable. Therefore, an ultra-thin arc-shaped stress-free packaging component for lithium batteries is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an ultra-thin arc-shaped lithium battery stress-free packaging assembly, including a fixing plate 1, which fixes an external mechanism. A stress-free packaging mechanism 2 is installed on the top of the fixing plate 1, which performs stress-free packaging of the energy storage device 9. A bottom shell 3 is fixedly connected to the top of the fixing plate 1, which protects and supports the internal structure. An automatic forming mechanism 4 is installed inside the bottom shell 3, which automatically forms and packages the energy storage device 9. A turntable 5 is fixedly connected to the outside of the fixing plate 1, which drives the fixing plate 1 to rotate and achieve assembly line operation. A support column 6 is fixedly connected inside the turntable 5, which drives the turntable 5 to rotate. A base plate 7 is rotatably connected to the bottom of the support column 6, which supports the upper main structure. A packaging paper 8 is detachably connected to the top of the automatic forming mechanism 4, which packages and protects the energy storage device 9. The energy storage device 9 is detachably connected to the top of the packaging paper 8, and the packaged main body of the energy storage device 9 can supply power to most objects.

[0033] The stress-free encapsulation mechanism 2 includes a top cover 21, which supports the step-down assembly 23. A protective box 22 is fixedly connected to the outside of the top cover 21. The protective box 22 protects the step-down unit 231 from external damage. A sealing ring 24 is fixedly connected to the top of the top cover 21. The sealing ring 24 seals the internal structure to maintain internal pressure reduction. The step-down assembly 23 is fixedly connected inside the protective box 22. After sealing, the step-down assembly 23 performs stress-free encapsulation of the internal step-down energy storage material 9.

[0034] Reference Figures 1 to 3The step-down assembly 23 includes a step-down compressor 231, which reduces the internal pressure. The drive end of the step-down compressor 231 is fixedly connected to a pipe 232, which serves as the suction pipe of the step-down compressor 231 and connects to the inside. The top cover 21 has a step-down groove 233 inside, which prevents the energy storage device 9 from being subjected to stress. The pipe 232 is fixedly connected to the inside of the top cover 21, and the step-down compressor 231 is fixedly connected to the outside of the top cover 21.

[0035] Reference Figures 2 to 4 The automatic forming mechanism 4 includes a second protective box 41, which protects the motor 431 from external damage. Two slide rods 42 are fixedly connected inside the bottom shell 3, which limit the slider 435. A limit rod 45 is fixedly connected inside the bottom shell 3, which limits the flip rod 44. The flip rod 44 is rotatably connected to the outside of the limit rod 45. The flip rod 44 drives the top cover 21 to flip so that it seals with the bottom shell 3. A drive assembly 43 is fixedly connected inside the second protective box 41. The drive assembly 43 drives the internal structure. The drive assembly 43 includes a motor 431, which drives the rotating rod 432 to rotate. The drive end of the motor 431 is fixedly connected to the rotating rod 432. The rotating rod 432 drives the gear 433 to rotate by its own rotation.

[0036] A gear 433 is fixedly connected to the outside of the rotating rod 432. The gear 433 drives the rack 434 to move by rotating itself. The rack 434 is fixedly connected to the outside of the two sliding rods 42. The rack 434 drives the slider 435 to slide by moving itself. The slider 435 is fixedly connected to the outside of the rack 434. The slider 435 drives the flip rod 44 to flip by moving itself. The outside of the flip rod 44 is rotatably connected to the inside of the slider 435. The outside of the gear 433 is meshed with the bottom of the rack 434. The bottom of the motor 431 is fixedly connected to the inside of the bottom shell 3. The top of the bottom shell 3 is detachably connected to the top of the sealing ring 24.

[0037] Working principle: After the bottom shell 3 and top cover 21 are sealed, the operator starts the pressure reducing machine 231. The inside of the pressure reducing machine 231 and the pressure reducing tank 233 are connected through the pipe 232, so that the pressure reducing machine 231 can discharge the internal gas to reduce the pressure. This allows the sealing paper 8 to seal the energy storage device 9 under low pressure, thereby achieving the effect of stress-free sealing. In addition, the internal pressure can be changed by controlling the working time of the pressure reducing machine 231 to achieve the effect of adapting to different models of energy storage devices 9. The internal air pressure drop makes the sealing paper 8 adhere to the surface of the energy storage device 9 to enhance the sealing performance.

[0038] First, the operator starts the motor 431, which drives the rotating rod 432 to rotate. The rotating rod 432, in turn, drives the gear 433 to rotate, which in turn drives the rack 434 to move. The rack 434, in turn, drives the slider 435 to move, which in turn drives the flip rod 44 to flip. The flip rod 44, in turn, flips the top cover 21, which in turn folds the sealing paper 8 and wraps the energy storage device 9. The top cover 21, in turn, reaches the top of the bottom shell 3 and forms a seal with it, thus achieving an automatic flip-top sealing effect. The flipping of the sealing paper 8 also performs initial sealing of the energy storage device 9.
