Description

Technical Field

[0001] This utility model relates to the field of battery top cover technology, specifically to a disassembly tool for the positive and negative terminals of a lithium battery top cover. Background Technology

[0002] The recycling and dismantling of lithium battery top covers is an important part of the lithium battery recycling process. It involves the environmentally friendly treatment of waste batteries and the reuse of resources. Copper and aluminum are widely used in the manufacture of lithium battery top covers due to their excellent conductivity and lightweight properties.

[0003] The main raw materials for lithium battery top covers are copper and aluminum, which result in high manufacturing costs. This is because the battery is made of a composite of multiple materials, making it very difficult to separate. Furthermore, the positive and negative terminals of the lithium battery top cover are laser-welded to the top cover, resulting in high welding strength.

[0004] Using conventional tooling to remove the top cover results in low residual value when sold directly as scrap, or the positive and negative terminals become deformed after removal, rendering it unusable. Therefore, it is necessary to develop a device that can effectively and quickly remove the positive and negative terminals from the top cover, thereby reducing scrap, lowering costs, and increasing the residual value of the scrap. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for disassembling the positive and negative terminals of a lithium battery top cover, so as to solve the technical problem that the positive and negative terminals of the battery top cover are inconvenient to remove in the prior art.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A disassembly fixture for the positive and negative terminals of a lithium battery top cover includes a base and a support frame. The support frame is fixedly connected to the top of the base and is an inverted L-shaped plate. The fixture also includes:

[0008] The top holding structure is fixed to the bottom end of the top plate of the support frame. The top holding structure includes a hydraulic cylinder, an upper pressure plate and guide columns. The hydraulic cylinder is fixed on the support frame. The driving end of the hydraulic cylinder is connected to the upper pressure plate. Guide columns are provided at both ends of the bottom of the upper pressure plate. A top block is detachably connected to the bottom of the guide column. The top block is made of Pyronite.

[0009] The placement structure includes a support plate, a lower pressure plate, and a material discharge hole. Several support columns are distributed at the four corners of the top of the base. The end of each support column away from the base is connected to the support plate. The two ends of the top of the support plate are symmetrically fixed with lower pressure plates. Each lower pressure plate has a limit structure at its top. A material discharge hole is vertically opened through the lower pressure plate and is aligned with the corresponding top block.

[0010] As a further embodiment of this utility model: a material discharge groove is provided in the middle of the support plate, and all the material discharge holes are connected to the material discharge groove.

[0011] As a further embodiment of this utility model: the limiting structure includes a limiting block, a slider, and a positioning structure. The limiting block is U-shaped, and the groove of the limiting block faces the side corresponding to the material discharge hole. Sliders are connected to both sides of the limiting block. The top of the lower pressure plate has a groove aligned with the slider. The slider is slidably connected to the inside of the groove. The slider cooperates with the positioning structure.

[0012] As a further embodiment of this utility model: the positioning structure includes a positioning groove and a screw. A plurality of positioning grooves are provided. The positioning grooves are opened on the front and rear sides of the lower pressure plate in parallel with the sliding groove direction and are connected to the sliding groove. The end of the screw is threadedly connected to the slider, and the screw is slidably connected to the positioning groove.

[0013] As a further embodiment of this utility model: a connecting hole is opened at one end of the guide post near the top block, and a plastic block is fixed on the side of the top block near the guide post, and the connecting hole is interference-fitted with the plastic block.

[0014] As a further embodiment of this utility model: a material collection area is formed between the support column and the support plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model, by setting up a top holding structure and a placement structure, places the battery top cover between two limiting blocks on the lower pressure plate, so that the positive and negative terminals of the battery top cover are aligned with the corresponding material drop holes. The limiting blocks can fix the top cover to prevent it from moving. The hydraulic cylinder is activated, which simultaneously drives the upper pressure plate and guide column to move downward. The top block abuts against the positive and negative terminals. The top block continues to move, thereby separating the positive and negative terminals from the top cover. The terminals fall from the material drop holes into a material drop collection area between the support column and the support plate, which is convenient for later collection. Since the top block is made of acetal steel, the acetal steel material can ensure that the terminals will not be damaged when the top block and the top cover come into contact. This equipment can effectively and quickly remove the positive and negative terminals on the top cover, and can reduce scrap and lower costs.

[0017] 2. This utility model features an adjustable limiting block to prevent the top cover from moving when the guide post holds the positive and negative terminals. The limiting blocks move in opposite directions and are then fixed by a positioning structure, making it suitable for fixing top covers of different sizes. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-Figure 4 As shown, a disassembly tool for the positive and negative terminals of a lithium battery top cover includes a base 1 and a support frame 7. The support frame 7 is fixedly connected to the top of the base 1 and is an inverted L-shaped plate. It also includes a top holding structure and a placement structure.

[0026] The top support structure is fixed to the bottom of the top plate of the support frame 7. The top support structure includes a hydraulic cylinder 8, an upper pressure plate 9 and a guide column 10. The hydraulic cylinder 8 is fixedly connected to the support frame 7. The driving end of the hydraulic cylinder 8 is fixedly connected to the upper pressure plate 9. Guide columns 10 are fixedly installed at both ends of the bottom of the upper pressure plate 9. The hydraulic cylinder 8 is used to drive the guide column 10 to move up and down. A top block 13 is detachably connected to the bottom of the guide column 10. The top block 13 is made of acetal steel. The acetal steel material can ensure that the terminals will not be damaged when the top block 13 contacts the top cover.

[0027] The placement structure includes a support plate 3, a lower pressure plate 5, and a discharge hole 6. Several support columns 2 are distributed at the four corners of the top of the base 1. The end of each support column 2 away from the base 1 is connected to the support plate 3. The two ends of the support plate 3 are symmetrically fixed with lower pressure plates 5 to prevent the battery top cover from being removed. The lower pressure plate 5 has a vertical discharge hole 6 through it. The two discharge holes 6 are aligned with the positive and negative terminals of the battery, respectively. Each lower pressure plate 5 has a limit structure at its top. The discharge hole 6 is aligned with the corresponding top block 13. The discharge hole 6 is used to push off the positive and negative terminals.

[0028] In some specific implementation plans, such as Figure 4 As shown, in order to facilitate the falling of the disassembled terminals, a material drop groove 4 is opened in the middle of the support plate 3, and the material drop holes 6 are all connected to the material drop groove 4. The disassembled terminals fall from the material drop holes 6 and the material drop groove 4.

[0029] In some specific implementation plans, such as Figure 1 As shown, in order to facilitate the fixing of top covers of different sizes, the limiting structure includes a limiting block 14, a slider 16, and a positioning structure. The limiting block 14 is U-shaped, and the groove of the limiting block 14 faces the side corresponding to the material drop hole 6. A placement groove is formed between the two limiting blocks 14. The sliders 16 are connected to both sides of the limiting block 14 respectively. The top of the lower pressure plate 5 has a sliding groove 15 aligned with the slider 16. The slider 16 is slidably connected to the inside of the sliding groove 15. The slider 16 cooperates with the positioning structure. The two limiting blocks 14 can fix the battery top cover and prevent the top cover from moving when the guide post 10 holds the positive and negative terminals. At the same time, the limiting blocks 14 move towards each other, and then the positioning structure is used to fix the limiting blocks 14. This can be used for top covers of different sizes.

[0030] In some specific implementation plans, such as Figure 1 or Figure 2 As shown, in order to facilitate the fixing of the limiting block 14, the positioning structure includes a positioning groove 17 and a screw 18. Several positioning grooves 17 are provided. The positioning grooves 17 are opened on the front and rear sides of the lower pressure plate 5 in a direction parallel to the slide groove 15 and are connected to the slide groove 15. The end of the screw 18 is threadedly connected to the slider 16. The screw 18 is slidably connected to the positioning groove 17. When the screw 18 is turned, the screw 18 moves towards the direction close to the discharge hole 6 until the end of the screw 18 abuts against the slide groove 15. The screws 18 on both sides abut against the corresponding slide grooves 15, so that the limiting block 14 can be fixed.

[0031] In some specific implementation plans, such as Figure 4 As shown, in order to facilitate the replacement of the top block 13, the guide post 10 has a connecting hole 11 at one end near the top block 13, and a plastic block 12 is fixed on the side of the top block 13 near the guide post 10. The connecting hole 11 and the plastic block 12 are connected by an interference fit. When the top block 13 is worn and needs to be replaced, a tool can be inserted into the connection gap between the guide post 10 and the top block 13 to disassemble the top block 13, making replacement convenient.

[0032] In some specific implementation plans, such as Figure 4 As shown, in order to facilitate the collection of disassembled terminals, a material collection area is formed between the support column 2 and the support plate 3. The positive and negative terminals fall into the material collection area for easy collection.

[0033] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0034] Before starting work, adjust the limiting blocks 14 on both sides so that the placement groove formed between the two limiting blocks 14 corresponds to the length of the battery top cover. While moving the limiting blocks 14, the limiting blocks 14 drive the bottom slider 16 to slide along the slide groove 15. When it slides to the appropriate position, turn the screw 18. Since the screw 18 is threadedly connected to the slider 16, while rotating, the screw 18 moves towards the discharge hole 6 until the end of the screw 18 abuts against the side wall of the slide groove 15, thus fixing the limiting blocks 14. Then, place the battery top cover between the two limiting blocks 14 on the lower pressure plate 5, so that the positive and negative terminals of the battery top cover are aligned with the corresponding discharge holes. 6. The limit block 14 can fix the top cover and prevent it from moving. When the hydraulic cylinder 8 is activated, the upper pressure plate 9 and the guide column 10 are moved downwards in sync. The top block 13 connected to the bottom of the guide column 10 abuts against the positive and negative terminals. The hydraulic cylinder 8 continues to move, thereby separating the positive and negative terminals from the top cover. The terminals fall from the drop hole 6 into the space between the support column 2 and the support plate 3 to form a drop collection area for easy collection later. Since the top block 13 is made of acetal steel, the acetal steel material can ensure that the terminals will not be damaged when the top block 13 contacts the top cover. When the top block 13 needs to be replaced, the top block 13 is connected to the connection hole 11 by the plastic block 12 through an interference fit, which is convenient for replacement.

[0035] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
