Description

Technical Field

[0001] This utility model relates to the field of battery material recycling, and in particular to a lithium-ion battery material recycling and dismantling clamping base. Background Technology

[0002] With the rapid development of new energy vehicles, energy storage, and consumer electronics, the annual production and stock of lithium-ion batteries continue to climb. At the same time, the limited lifespan of lithium-ion batteries has led to a gradual increase in the number of retired batteries. Retired batteries contain scarce metals such as lithium, cobalt, and nickel, as well as recyclable base materials. Direct disposal not only wastes resources but may also cause soil and water pollution due to electrolyte leakage and heavy metal leaching. Therefore, material recycling is essential.

[0003] Meanwhile, a battery dismantling device with application number CN202221909827.0 includes: a base, a guide rod, and a battery placement platform to be dismantled. The guide rod is installed on the base, and the battery placement platform to be dismantled is sleeved on the guide rod above the base. Two buffer elements are installed between the battery placement platform to be dismantled and the base. An adjustable limit adjustment cylinder is installed on the upper side of the guide rod above the battery placement platform to be dismantled. The adjustment cylinder includes: a cylinder, and a ceramic cutter is installed at one end of the cylinder's output shaft.

[0004] However, the following problems were found in the implementation of the relevant technology: the current lithium-ion battery shell is relatively thin and the internal electrode is relatively fragile. The cylinder relies on a pneumatic pressure source for drive, and the pneumatic pressure is easily affected by the fluctuation of the pneumatic source, resulting in the clamping force fluctuating. The above-mentioned battery disassembly equipment has certain shortcomings. It disassembles the battery by means of a cylinder and also requires adjustment of the limit nut to adjust the cylinder stroke, which is inconvenient and cannot apply force slowly. At best, it will cause the soft-pack battery shell to crack and the electrolyte to leak. At worst, it will squeeze and deform the internal electrode of the cell, causing short circuit or thermal runaway and damaging recyclable materials. Utility Model Content

[0005] The main purpose of this utility model is to provide a lithium-ion battery material recycling and dismantling clamping base, which solves the problem that the current lithium-ion battery shell is relatively thin, the internal electrode is relatively fragile, and the cylinder relies on a pneumatic pressure source for drive, and the pneumatic pressure is easily affected by the fluctuation of the pneumatic pressure source, resulting in inconsistent clamping force.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a lithium-ion battery material recycling and dismantling clamping base, including a processing base, characterized in that: a placement groove is opened at the top of the processing base, a fixing frame is connected to the top of the processing base, four guide grooves are opened on the surface of the processing base, a cylinder is connected to the surface of the fixing frame, a drive source is connected to the inner wall of the back of the cylinder, and a transmission component and a reset component are respectively provided on the cylinder; The surface of the transmission component is connected to the power output end of the drive source to drive the transmission component to perform a vertical lifting motion to press the lithium-ion battery material. The surface of the reset component is electrically connected to the power output end of the transmission component to drive the transmission component to move upward and reset.

[0007] In a preferred embodiment, the transmission assembly includes a toothed gear, a rack plate, a support plate, and a support rod. The surface of the toothed gear is electrically connected to the power output end of the drive source. The rack plate is meshed with the toothed gear. A connecting rod is connected to the bottom end of the rack plate, and a clamping block is connected to the bottom end of the connecting rod. The support plate is disposed on the inner wall of one side of the cylinder, and the support rod is disposed on the inner wall of the front side of the cylinder.

[0008] In a preferred embodiment, the surface of the support plate is slidably connected to the inner side of the rack plate.

[0011] In a preferred embodiment, the surface of the slide bar is slidably connected to the inner side of the fixing frame, and the inner side of the slide plate is slidably connected to the surface of the fixing frame.

[0012] In a preferred embodiment, the two ends of the contraction spring are connected to the top of the slide plate and the surface of the fixing frame, respectively.

[0013] This utility model provides a clamping base for recycling and dismantling lithium-ion battery materials. Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model facilitates the rotation of the toothed gear through a drive source. The shape and number of teeth of the toothed gear help ensure that the downward displacement of the rack plate is consistent each time. Compared with the problem of inconsistent clamping force caused by the cylinder, it is more gentle and helps to adapt to lithium-ion battery materials of the same batch and size. There is no need for repeated manual adjustments. Furthermore, the support plate helps to improve the stability of the rack plate, connecting rod and clamping block in the vertical direction of adjustment.

[0014] 2. This utility model utilizes the elastic contraction of the spring to facilitate the upward repositioning of the rack plate when the surface of the toothless gear approaches the rack plate. This helps to quickly lift the rack plate to detach it from the upper surface of the lithium-ion battery material. Operators can remove the lithium-ion battery material without manually lifting the clamping block, thus improving the cycle efficiency of clamping, repositioning, and re-clamping the battery. This is beneficial for adapting to batch disassembly scenarios. Attached Figure Description

[0017] like Figure 1-4 As shown, this utility model provides a lithium-ion battery material recycling and dismantling clamping base, including a processing base 1. The top of the processing base 1 is provided with a placement groove to facilitate the placement of lithium-ion battery materials. The top of the processing base 1 is connected to a fixing frame 4. The surface of the processing base 1 is provided with four guide grooves 5. The surface of the fixing frame 4 is connected to a cylinder 6. The inner wall of the back of the cylinder 6 is connected to a drive source 7 to facilitate the provision of driving force. The cylinder 6 is respectively provided with a transmission component 2 and a reset component 3. The surface of the transmission component 2 is poweredly connected to the power output end of the drive source 7 to drive the transmission component 2 to perform vertical lifting and lowering motion to press the lithium-ion battery material. The surface of the reset component 3 is electrically connected to the power output end of the transmission component 2 to drive the transmission component 2 to move upward and reset.

[0018] Specifically, the transmission assembly 2 includes a toothed gear 21, a rack plate 22, a support plate 25, and a support rod 26. The surface of the toothed gear 21 is connected to the power output end of the drive source 7. The rack plate 22 is meshed with the toothed gear 21. The shape characteristics of the toothed gear 21 facilitate the downward displacement of the rack plate 22. A connecting rod 23 is connected to the bottom end of the rack plate 22, and a clamping block 24 is connected to the bottom end of the connecting rod 23 to facilitate the clamping operation of the lithium-ion battery material. The support plate 25 is set on the inner wall of one side of the cylinder 6, and the support rod 26 is set on the inner wall of the front side of the cylinder 6.

[0019] Furthermore, the surface of the support plate 25 is slidably connected to the inner side of the rack plate 22, which improves the stability of the movement of the rack plate 22.

[0020] Furthermore, one end of the support rod 26 is rotatably connected to the surface of the toothed gear 21, which facilitates providing support force to the toothed gear 21 and improves the rotational stability of the toothed gear 21.

[0021] It is worth noting that the reset assembly 3 includes a slide bar 31 and a retraction spring 33. The slide bar 31 is located at the top of the rack plate 22, which improves the stability of the movement of the rack plate 22. A sliding plate 32 is connected to the surface of the slide bar 31, and the retraction spring 33 is sleeved on the outside of the slide bar 31 to facilitate the provision of retraction force.

[0022] It is worth noting that the surface of the slide bar 31 is slidably connected to the inner side of the fixed frame 4, and the inner side of the slide plate 32 is slidably connected to the surface of the fixed frame 4, which facilitates the improvement of the stability of the vertical lifting adjustment of the rack plate 22.

[0023] In the preferred embodiment, the retraction spring is positioned between the fixed frame and the slide plate. The two ends of the retraction spring 33 are connected to the top of the slide plate 32 and the surface of the fixed frame 4, respectively, which facilitates the automatic lifting and repositioning of the rack plate 22. Operators can remove the lithium-ion battery materials without manually lifting the rack plate 22, thereby improving the cycle efficiency of pressing, repositioning, and repressing the battery and helping to adapt to batch disassembly scenarios.

[0024] Working principle: First, the lithium-ion battery material is placed in the placement slot at the top of the processing base 1. Then, the toothed gear 21 is driven to rotate by the drive source 7. The toothed gear 21 drives the rack plate 22 that meshes with it to adjust its height. At this time, the rack plate 22 is driven to descend. The rack plate 22 drives the clamping block 24 to descend, thus clamping the lithium-ion battery material. The shape characteristics and number of teeth of the toothed gear 21 ensure that the downward displacement of the rack plate 22 is consistent. Compared with the problem of the clamping force fluctuating due to the cylinder, it is more gentle and helps to adapt to lithium-ion battery materials of the same batch and size. There is no need for repeated manual adjustment. When the rack plate 22 moves up and down, the support plate 25 improves the stability of the rack plate 22, connecting rod 23 and clamping block 24 in the vertical direction. After the pressing operation of the lithium-ion battery material is completed, the toothless surface of the toothed gear 21 is close to the rack plate 22, meaning that the meshing force between the rack plate 22 and the toothed gear 21 is lost. At this time, under the elastic contraction of the retraction spring 33, the rack plate 22 is automatically lifted and reset. By automatically lifting the rack plate 22 and resetting it from the upper surface of the lithium-ion battery material, the operator can remove the lithium-ion battery material without manually lifting the rack plate 22, which improves the cycle efficiency of pressing, resetting, and repressing the battery and helps to adapt to batch disassembly scenarios. It should also be noted that the displacement of the rack plate 22 pulled upward by the retraction spring 33 each time makes the helical gap on the retraction spring 33 close to zero, so that the upward displacement of the rack plate 22 each time is as consistent as possible, thereby improving the accuracy of the meshing correspondence between the toothed gear 21 and the rack plate 22.

[0025] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
