Description

Technical Field

[0001] This utility model relates to the field of battery cell storage technology, and in particular to a storage device for preventing misalignment in the production of lithium battery cells. Background Technology

[0002] In the production of lithium-ion battery cells, the efficiency of storing and retrieving cylindrical cells directly affects the smoothness of the production line, and traditional storage devices have significant technical drawbacks. While the tight-fitting structure of rubber septa designed to prevent cell misalignment and collisions ensures storage safety, it becomes an efficiency bottleneck in the retrieval process.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: workers need to spend a lot of time peeling off the battery cells one by one. Especially in large-scale production scenarios, frequent handling operations will accumulate into a considerable waste of working hours, and may even affect the timeliness of subsequent battery cell processing. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the existing technology, frequent access operations in large-scale production scenarios will accumulate into considerable waste of working time and even affect the timeliness of subsequent processing of battery cells. To this end, we propose a storage device for lithium battery cell production to prevent misalignment.

[0005] To achieve the above objectives, this application adopts the following technical solution: a storage device for lithium battery cell production to prevent misalignment, comprising a storage box, a rubber diaphragm installed inside the storage box, lifting devices on both sides of the storage box, the lifting devices comprising two fixed blocks, the two fixed blocks being fixedly connected to the two sides of the storage box respectively, a connecting plate being slidably inserted into each of the two fixed blocks, a base plate being fixedly connected to the side of the two connecting plates that are close to each other, a lifting rod being fixedly connected to the surface of the base plate, the arc surfaces of several lifting rods being slidably connected to the storage box, a fixed rod being fixedly connected to one side of the fixed block, an operating plate being slidably connected to the arc surface of the fixed rod, an insertion rod being fixedly connected to one side of the operating plate, and two insertion holes being formed on the surface of the connecting plate.

[0006] Preferably, one end of the fixing rod is fixedly connected to a limiting plate, and the size of the insertion rod is adapted to the size of the insertion hole of the connecting plate.

[0007] Preferably, a first spring is fitted onto the arc surface of the fixing rod, and the two ends of the first spring are fixedly connected to the operating plate and the fixing block, respectively.

[0008] Preferably, a rubber ring is fixedly connected to one side of the operating panel, and the rubber ring is slidably connected to the arc surface of the fixing rod.

[0009] Preferably, the upper surface of the storage box is provided with a protective device, the protective device including a protective plate, the protective plate being slidably connected to the upper surface of the storage box, a winding rod being fixedly connected to both sides of the protective plate, a winding rope being fixedly connected to both sides of the storage box, and a winding groove being formed on the arc surface of the winding rod.

[0010] Preferably, one end of the winding rope is fixedly connected to an elastic ring, the size of which is adapted to the size of the winding rod.

[0011] Preferably, a soft pad is fixedly connected to the surface of the protective plate, and the soft pad is made of rubber.

[0012] Preferably, a sealing ring is fixedly connected to the side of the protective plate near the soft pad, the sealing ring is fixedly connected to the surface of the soft pad, and the sealing ring is slidably connected to the upper surface of the storage box.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, by setting up a lifting device, the cylindrical battery cells stored in the storage box and separated by rubber septa are quickly retrieved. This avoids the situation where the rubber septa wrap the cylindrical battery cells too tightly when the staff needs to remove the cylindrical battery cells from the storage box, making it difficult to remove the cylindrical battery cells one by one. This would cause the staff to spend a lot of time to remove the cylindrical battery cells one by one, thereby increasing the workload of the staff and improving the practicality of the device.

[0015] 2. In this utility model, by setting a protective device, the cylindrical battery cells in the storage box are shielded from dust, which avoids the situation where dust contaminates one end of the cylindrical battery cells when they are stored in the storage box, thus requiring the staff to clean them before use and increasing the workload of the staff. This improves the protective performance of the device. Attached Figure Description

Detailed Implementation

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figure 1 As shown, this utility model provides a technical solution: a storage device for lithium battery cell production to prevent misalignment, including a storage box 1, a rubber spacer 2 installed inside the storage box 1, and lifting devices 3 on both sides of the storage box 1. By setting the lifting devices 3, the cylindrical battery cells stored in the storage box 1 and separated by the rubber spacers 2 can be quickly retrieved. This avoids the situation where the rubber spacers 2 wrap the cylindrical battery cells too tightly when the workers need to remove the cylindrical battery cells from the storage box 1, making it difficult to remove the cylindrical battery cells one by one, thus increasing the workload of the workers. This improves the practicality of the device. The upper surface of the storage box 1 is provided with a protective device 4. By setting the protective device 4, the cylindrical battery cells in the storage box 1 are shielded from dust. This avoids the situation where dust contaminates one end of the cylindrical battery cells when using the storage box 1 to store the cylindrical battery cells, thus requiring the workers to clean them before use, which would increase the workload of the workers. This improves the protective performance of the device.

[0025] The specific setup and function of its lifting device 3 and protective device 4 will be explained below.

[0026] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the lifting device 3 includes two fixed blocks 301, which are fixedly connected to both sides of the storage box 1 respectively. A connecting plate 302 is slidably inserted into each of the two fixed blocks 301. A base plate 303 is fixedly connected to one side of the two connecting plates 302 that are close to each other. A lifting rod 304 is fixedly connected to the surface of the base plate 303. The arc surfaces of several lifting rods 304 are slidably connected to the storage box 1. A fixing rod 305 is fixedly connected to one side of the fixed block 301. An operating plate 306 is slidably connected to the arc surface of the fixing rod 305. A plug rod 307 is fixedly connected to one side of the operating plate 306. Two insertion holes are opened on the surface of the connecting plate 302. A limit plate 308 is fixedly connected to one end of the fixing rod 305. The size of the plug rod 307 is adapted to the size of the insertion hole in the connecting plate 302, thereby limiting the maximum sliding distance of the operating plate 306 on the arc surface of the fixing rod 305. The separation effect prevents the operating plate 306 from detaching from the arc surface of the fixing rod 305 due to excessive pulling force when the operator pulls it. The arc surface of the fixing rod 305 is fitted with a first spring 309, and the two ends of the first spring 309 are fixedly connected to the operating plate 306 and the fixing block 301, respectively. The first spring 309 achieves the effect of automatically bringing the insertion rod 307 into the insertion hole of the connecting plate 302, and at the same time improves the stability of the insertion rod 307 when limiting the connecting plate 302. A rubber ring 310 is fixedly connected to one side of the operating plate 306. The rubber ring 310 is slidably connected to the arc surface of the fixing rod 305. The elasticity of the rubber ring 310 wraps around the arc surface of the fixing rod 305, thereby reducing the sliding speed of the operating plate 306 on the arc surface of the fixing rod 305, thus reducing the impact of the external environment on the operating plate 306 and playing a damping role.

[0027] Reference Figure 2 and Figure 5As shown, specifically, the protective device 4 includes a protective plate 41, which is slidably connected to the upper surface of the storage box 1. Both sides of the protective plate 41 are fixedly connected to a winding rod 42, and both sides of the storage box 1 are fixedly connected to a winding rope 43. The arc surface of the winding rod 42 has a winding groove. One end of the winding rope 43 is fixedly connected to an elastic ring 44, the size of which matches the size of the winding rod 42, achieving the effect of wrapping and limiting the winding rope 43, further improving the protection of the cylindrical battery cell. A soft pad 45, made of rubber, is fixedly connected to the surface of the protective plate 41, providing protection for one end of the cylindrical battery cell. The protective plate 41 is designed to prevent collisions and damage to the cylindrical cells caused by shaking during transportation. A sealing ring 46 is fixedly connected to the side of the protective plate 41 near the soft pad 45. The sealing ring 46 is fixedly connected to the surface of the soft pad 45 and slidably connected to the upper surface of the storage box 1. The sealing ring 46 increases the sealing performance of the protective plate 41, preventing liquid from splashing onto the surface of the protective plate 41 and the storage box 1. This would prevent some liquid from entering the storage box 1 through the gap between the protective plate 41 and the storage box 1, thus causing the cells inside the storage box 1 to become damp.

[0028] Working principle: When it is necessary to remove the cylindrical battery cell from the rubber septum 2, the operator pulls the operating plate 306. The operating plate 306 overcomes the elastic force of the first spring 309 and slides on the fixed rod 305, causing the insertion rod 307 to be pulled out from the insertion hole of the connecting plate 302, releasing the limit on the connecting plate 302. At this time, under the action of gravity, the lifting rod 304 drives the bottom plate 303 to slide upward in the storage box 1 until the bottom plate 303 is in contact with the lower surface of the storage box 1. At this time, the operating plate 306 is released, and the first spring 309 is released. Spring 309 releases its rebound force, causing the insertion rod 307 to automatically insert into the corresponding insertion hole of the connecting plate 302, fixing the connecting plate 302 onto the fixing block 301, thus stabilizing the base plate 303. During this process, the limiting plate 308 restricts the sliding distance of the operating plate 306 to prevent it from detaching from the fixing rod 305. The rubber ring 310 wraps around the fixing rod 305 with elasticity, slowing down the sliding speed of the operating plate 306, reducing the impact of external vibrations on the positioning of the base plate 303, and ensuring the stable support of the lifting rod 304.

[0029] When storing or transporting cylindrical battery cells, the protective plate 41 is slid along the upper surface of the storage box 1 to cover the opening. The rubber pad 45 on the surface of the protective plate 41 abuts against the end of the battery cell to prevent collision damage caused by shaking during transportation. The sealing ring 46 is attached to the upper surface of the storage box 1 to prevent liquid from seeping in from the gaps and to avoid the battery cell getting damp. Then, the winding ropes 43 on both sides are wrapped around the winding rod 42 of the protective plate 41, and the end of the winding rod 42 is wrapped with an elastic ring 44 to fix the winding ropes 43 and prevent the protective plate 41 from falling off. When the battery cell needs to be retrieved, the elastic ring 44 is untied, the winding ropes 43 are loosened, and the protective plate 41 is slid off the upper surface of the storage box 1. This device achieves anti-collision and moisture protection for the cylindrical battery cell through the cooperation of the pad 45, the sealing ring 46 and the winding structure.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
