Description

Technical Field

[0001] This utility model generally relates to the field of lithium battery technology. More specifically, this utility model relates to a battery cell electrode roll transfer fixture. Background Technology

[0002] Cell electrode rolls are key components of battery cells. They are rolls formed by uniformly coating active materials (such as positive electrode materials like lithium cobalt oxide and lithium iron phosphate in lithium-ion batteries, and negative electrode materials like graphite) onto metal foil (aluminum foil is commonly used for positive electrodes, and copper foil is commonly used for negative electrodes) and then processing them through a series of steps (such as drying to remove solvents, rolling to adjust thickness and density).

[0003] Because the battery cell coils also need to be baked before use to remove moisture, the baking process requires transferring the coils. Currently, the common practice is to directly place the core support located in the middle of the coil onto a fork arm in a controlled environment after baking to transport the coil. This method of transfer may result in uneven transport conditions, and the coil may be subjected to irregular vibrations due to the shaking of the handling equipment. This can cause relative displacement between the layers inside the coil, leading to the coil becoming loose.

[0004] In view of this, there is an urgent need to provide a battery cell electrode roll transfer tool to solve the problem. Utility Model Content

[0005] To address at least one or more of the technical problems mentioned in the background section, this invention proposes a battery cell electrode roll transfer fixture.

[0006] Therefore, the present invention provides the following technical solution.

[0007] This utility model discloses a battery cell electrode roll transfer fixture, comprising: a sealed box having a sealed door structure, a suspension assembly for suspending the battery cell electrode roll inside the box, and a locking structure for clamping the battery cell electrode roll to prevent relative displacement between the battery cell electrode roll and the suspension assembly.

[0008] Preferably, the suspension assembly includes a horizontal cantilever, the first end of which is fixedly connected to the back of the housing to allow the center hole of the core support of the battery cell electrode coil to be fitted onto and suspended from the second end of the horizontal cantilever, and a first through hole is provided therein in the diametrical direction; the locking structure includes a fixing ring and an adjusting ring, the fixing ring being fixed to the horizontal cantilever, the adjusting ring coinciding with the central axis of the fixing ring, and the adjusting ring being able to move closer to or away from the fixing ring along the direction of the central axis of the fixing ring.

[0009] Preferably, the fixing ring has a preset thickness and is provided with a second through hole and a third through hole along the diameter direction of the fixing ring. The fixing ring is used to be fitted from the second end of the horizontal cantilever to reach the first through hole. It also includes a positioning pin, which is used to pass through the second through hole, the first through hole and the third through hole at the same time to limit the relative displacement between the fixing ring and the horizontal cantilever.

[0010] Preferably, at least three guide holes are provided on the fixed ring along the direction of its central axis, and the guide holes are evenly distributed relative to the central axis of the fixed ring. The adjusting ring is fixed with the same number of guide posts as the guide holes, and the guide posts are used to pass through the corresponding guide holes. The adjusting ring is also provided with at least three threaded holes, and the threaded holes are evenly distributed relative to the central axis of the fixed ring. The central axis of the threaded holes is parallel to the central axis of the fixed ring. The adjusting ring also includes the same number of screws as the threaded holes. The screws are used to pass through the fixed ring with a preset thickness along the direction of the central axis of the fixed ring and are threadedly connected to the threaded holes, so that when the screws are screwed, the adjusting ring can move closer to or further away from the fixed ring.

[0011] Preferably, the upper surface of the horizontal cantilever is provided with a plurality of universal ball bearings.

[0012] Preferably, a gasket is provided at the first end of the horizontal cantilever, the gasket being used to limit the innermost position that the cell electrode coil can reach when entering the housing along the horizontal cantilever.

[0024] Embodiments will now be described with reference to the accompanying drawings. It should be understood that, for the sake of simplicity and clarity, reference numerals may be repeated in the drawings to indicate corresponding or similar elements where deemed appropriate. Furthermore, numerous specific details are set forth in this invention to provide a thorough understanding of the embodiments described herein. However, those skilled in the art will understand that the embodiments described herein can be practiced without these specific details. In other instances, well-known methods, processes, and components have not been described in detail so as not to obscure the embodiments described herein. Moreover, this description should not be construed as limiting the scope of the embodiments described herein.

[0025] According to one embodiment of the present invention, a battery cell electrode roll transfer fixture is provided, such as... Figure 1 and Figure 2 As shown, the device includes a sealed box 11 with a sealed door structure. Inside the box 11, there is a suspension assembly for suspending the battery cell electrode roll, and a locking structure for clamping the battery cell electrode roll so that the battery cell electrode roll does not move relative to the suspension assembly.

[0026] The box 11 and the sealing door structure mentioned above can adopt the existing battery cell drying box structure, which is existing technology and will not be described in detail here.

[0027] In one embodiment, the suspension assembly includes a horizontal cantilever 21, the first end of which is fixedly connected to the back of the housing 11 for suspending the center hole of the core support of the battery cell electrode coil through the second end of the horizontal cantilever 21. A first through hole 22 is provided vertically through the horizontal cantilever 21 along its diameter. The locking structure includes a fixing ring 23 and an adjusting ring 24. The fixing ring 23 is used to fix the horizontal cantilever 21, and the adjusting ring 24 coincides with the central axis of the fixing ring 23. The adjusting ring 24 can move closer to or away from the fixing ring 23 along the direction of the central axis of the fixing ring 23.

[0028] The fixed connection between the horizontal cantilever 21 and the back of the housing 11 mentioned above can be a flange connection structure.

[0029] The aforementioned fixing ring 23 is used to fix the horizontal cantilever 21, which can be achieved in the following way. Specifically, the fixing ring 23 has a preset thickness and is provided with a second through hole and a third through hole along the diameter direction of the fixing ring 23. The fixing ring 23 is used to be fitted onto the second end of the horizontal cantilever 21 to reach the first through hole 22. It also includes a positioning pin 31, which is used to pass through the second through hole, the first through hole 22 and the third through hole simultaneously to limit the relative displacement between the fixing ring 23 and the horizontal cantilever 21. When the fixing ring 23 is fitted onto the second end of the horizontal cantilever 21 and the first through hole 22 coincides with the second through hole and the third through hole simultaneously, the positioning pin 31 passes through the three through holes simultaneously, thereby limiting the displacement of the fixing ring 23 on the horizontal cantilever 21 in the axial and circumferential directions.

[0030] The structural arrangement of the fixed ring 23 and adjusting ring 24 mentioned above, and the function of the adjusting ring 24 to move closer to or away from the fixed ring 23 along the central axis of the fixed ring 23, can be achieved in the following way. Specifically, at least three guide holes (not shown in the figure) can be provided on the fixed ring 23 along the central axis of the fixed ring 23. Each guide hole is evenly distributed relative to the central axis of the fixed ring 23. The adjusting ring 24 is fixed with the same number of guide posts 41 as the guide holes. The guide posts 41 are used to pass through the corresponding guide holes. The adjusting ring 24 is also provided with at least three threaded holes. Each threaded hole is evenly distributed relative to the central axis of the fixed ring 23. The central axis of the threaded holes is parallel to the central axis of the fixed ring 23. The adjusting ring 24 also includes the same number of screws 42 as the threaded holes. The screws 42 are used to pass through the fixed ring 23 with a preset thickness along the central axis of the fixed ring 23 and are threadedly connected to the threaded holes, so that when the screws 42 are screwed, the adjusting ring 24 can move closer to or away from the fixed ring 23. It is easy to understand that the cooperation between the guide post 41 and the guide hole plays an auxiliary role in the process of the adjusting ring 24 moving closer to or further away from the fixed ring 23, so as to keep the adjusting ring 24 from tilting relative to the fixed ring 23 as much as possible. When adjusting the position of the adjusting ring 24, each screw 42 can be turned in multiple turns, one to two turns each time, to prevent over-tightening.

[0031] Since the width of the battery cell electrode roll is fixed, it can be configured to suspend one or two battery cell electrode rolls on the horizontal cantilever 21, depending on the size of the manufactured housing 11 or the baking requirements. If sometimes two battery cell electrode rolls are suspended and sometimes one battery cell electrode roll is suspended, such as... Figure 3 and Figure 4 As shown, according to this requirement, the length of the horizontal cantilever 21 is greater than the width of the two cell electrode rolls. In this case, two first through holes 22 can be provided at the first end of the horizontal cantilever 21 and approximately near the middle position.

[0032] In other embodiments, the upper surface of the horizontal cantilever 21 is provided with a plurality of universal ball bearings 51. This is clearly to reduce the friction between the core support of the battery cell coil and the horizontal cantilever 21 by causing rolling friction during the process of the core support being fitted onto the horizontal cantilever 21.

[0033] In some other embodiments, a gasket 61 is provided at the first end of the horizontal cantilever 21. It is easy to understand that the gasket 61 is used to limit the innermost position that the cell electrode roll can reach when it enters the housing 11 along the horizontal cantilever 21.

[0034] Wheels can also be provided at the bottom of the box 11 for easy movement.

[0035] Additionally, a push-pull handle is provided on the side of the housing 11.

[0036] In other embodiments, each of the wheels is further provided with a support leg for supporting the housing 11 without moving it so that the wheel does not touch the ground.
