Description
Technical Field
[0001] This utility model relates to a battery disassembly device, and in particular to an electrode separation guide structure. Background Technology
[0002] Refined dismantling of battery cells is a key technology for achieving efficient recycling and resource reuse of waste batteries. Its core objective is to safely and environmentally extract valuable materials from batteries, such as positive and negative electrode materials, electrolytes, and separators. During the dismantling process, pretreatment is required to ensure the safety and operability of the dismantling. Then, the outer casing is cut by mechanical cutting to separate the outer casing from the core. The positive and negative electrode sheets and separators in the core are efficiently separated. The separated electrode sheets are then further recycled and purified by separating the active material and current collector separately. During the electrode separation process, the separator and positive electrode need to be concentrated in a shearing device to cut the electrode sheets and separator into individual pieces.
[0003] In existing technology, before cutting the separator and positive electrode, the separator and positive electrode are guided by a guide structure to facilitate them reaching the correct position. However, due to the curvature of the rolled core package, the part of the core package between the guide structure and the shearing structure is prone to bending. This results in insufficient tension in the core package part entering the shearing position, and the cut core packages are of different sizes. It may even affect the separation of the negative electrode and the separator at the front end, reducing the efficiency of electrode separation.
[0004] Therefore, this invention aims to provide an electrode separation guide structure that can guide the core package portion after the negative electrode has been separated while providing a certain tension to the core package, allowing the core package to move quickly and accurately between the guide structure and the shearing structure, ensuring the shearing accuracy without affecting the previous separation steps. Utility Model Content
[0005] This invention provides an electrode separation and guiding structure that can effectively solve the above problems.
[0006] This utility model is implemented as follows:
[0007] An electrode separation and guiding structure includes: a separation guide gantry, wherein a vertically movable guide roller group is provided on the inner side of the separation guide gantry, the guide roller group being used for passing through a core package, and further comprising:
[0008] The core package separation guide assembly includes a guide air knife disposed on the side of the guide roller group away from the feed direction. A guide pressure plate is disposed below the guide air knife and connected to the separation guide gantry. A core package separation pressure structure is also disposed on the side of the separation guide gantry near the guide pressure plate. After being guided by the guide roller group, the core package adheres to the guide pressure plate under the downward action of the guide air knife. After the core package separation pressure structure is pushed out, it is pressed tightly onto the guide pressure plate.
[0009] As a further improvement, a moving guide roller drive is provided at the top of the separation guide gantry, and a moving guide roller mounting seat is provided at the bottom of the moving guide roller drive. The top of the moving guide roller mounting seat is connected to the separation guide gantry through at least two moving guide roller limiting rods. The guide roller group includes a moving guide roller disposed inside the moving guide roller mounting seat. A fixed guide roller is provided at the bottom of the inner side of the separation guide gantry. One side of the fixed guide roller is driven by a fixed guide roller drive.
[0010] As a further improvement, the guide air knife component includes a guide air knife mounting bracket locked on the moving guide roller mounting seat, and the bottom end of the guide air knife mounting bracket is provided with a guide air knife.
[0011] As a further improvement, the guide bearing plate is a square plate, and the side of the guide bearing plate facing the guide air knife has a rounded corner.
[0012] As a further improvement, a side ear seat is provided on the outer side of the separation guide gantry, and the core package separation pressure structure includes a pressure guide rod locked on the side ear seat. A core package separation pressure seat is slidably installed on the pressure guide rod. A core package separation positioning seat is provided on the side of the core package separation pressure seat away from the side ear seat and is slidably connected to the pressure guide rod. A core package separation driving component is installed on the core package separation positioning seat, and the output end of the core package separation driving component is connected to the core package separation pressure seat.
[0013] As a further improvement, the core-packet separation pressure seat includes a core-packet separation sleeve fitted onto the pressure guide rod. The core-packet separation sleeve is locked onto a core-packet separation synchronization plate. The side of the core-packet separation synchronization plate away from the guide pressure plate is connected to the core-packet separation drive component. The side of the core-packet separation synchronization plate close to the guide pressure plate is locked with a core-packet separation pressure plate adapted to the guide pressure plate.
[0014] The beneficial effects of this utility model are:
[0015] In existing systems, the core package between the guiding structure and the shearing structure is prone to bending, resulting in insufficient tension in the core package portion entering the shearing position. Therefore, this invention, through the setting of a core package separation and guiding component, allows the core package to be blown downwards immediately by the guiding air knife after passing through the guide roller group, so that the core package is laid on the guide bearing plate. At the same time, the core package separation and pressure application structure pushes out, pressing the core package onto the guide bearing plate, thereby making the starting position of the core package straight, and the continuously fed core packages are always output straight under the guidance of the guiding air knife and the guide bearing plate.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0024] Reference Figures 1-3 As shown, an electrode separation guiding structure includes: a separation guiding gantry 90, with a vertically movable guide roller group 91 disposed on the inner side of the separation guiding gantry 90, the guide roller group 91 being used for passing core packages; and a core package separation guiding assembly, including a guide air knife 92 disposed on the side of the guide roller group 91 away from the feed direction, a guide pressure plate 93 disposed below the guide air knife 92 and connected to the separation guiding gantry 90, and a core package separation pressure structure 94 disposed on the side of the separation guiding gantry 90 near the guide pressure plate 93. After being guided by the guide roller group 91, the core package adheres to the guide pressure plate 93 under the downward action of the guide air knife 92, and the core package separation pressure structure 94 presses against the guide pressure plate 93 after being pushed out.
[0025] In existing systems, the core package between the guide structure and the shearing structure is prone to bending, resulting in insufficient tension in the core package portion entering the shearing position. Therefore, this invention, through the core package separation guide assembly, allows the core package to be blown downwards by the guide air knife 92 immediately after passing through the guide roller group 91, so that the core package is laid on the guide pressure plate 93. At the same time, the core package separation pressure structure 94 is pushed out, pressing the core package onto the guide pressure plate 93, thereby making the starting position of the core package straight, and the continuously fed core packages are always output straight under the guidance of the guide air knife 92 and the guide pressure plate 93.
[0026] After the core package is initially gripped by the clamping structure, the power source for its continuous separation output comes from the guide roller group 91. Specifically, the top of the separation guide gantry 90 is provided with a moving guide roller drive 901, and the bottom of the moving guide roller drive 901 is provided with a moving guide roller mounting seat 902. The top of the moving guide roller mounting seat 902 is connected to the separation guide gantry 90 through at least two moving guide roller limiting rods 903. The guide roller group 91 includes a moving guide roller 911 disposed inside the moving guide roller mounting seat 902. The bottom of the inner side of the separation guide gantry 90 is provided with a fixed guide roller 912. One side of the fixed guide roller 912 is driven by a fixed guide roller drive 913, so that the moving guide roller 911 can be raised when the clamping structure passes through, and the moving guide roller 911 can be lowered when the core package needs to be transferred. The fixed guide roller 912 is driven by the fixed guide roller drive 913 to provide a backward force.
[0027] The guide air knife 92 needs to be positioned relatively close to the core package without interfering with other structures. Specifically, the guide air knife 92 includes a guide air knife mounting bracket 921 locked onto the moving guide roller mounting base 902. The bottom end of the guide air knife mounting bracket 921 is provided with a guide air knife 922, so that the guide air knife 922 can descend with the moving guide roller mounting base 902 to the position closest to the core package.
[0028] In order to better guide the core package's falling position, the guide pressure plate 93 is a square plate, and the side of the guide pressure plate 93 facing the guide air knife 922 has a rounded corner, and the bending position of the core package is always close to the rounded corner.
[0029] After being blown out, the starting point of the core package may be curved or uneven. If it falls directly into the shearing structure, it may be difficult to cut it evenly. Therefore, in this embodiment, a side ear seat 904 is provided on the outer side of the separation guide gantry 90. The core package separation pressure structure 94 includes a pressure guide rod 941 locked on the side ear seat 904. A core package separation pressure seat 942 is slidably installed on the pressure guide rod 941. A core package separation positioning seat 943 is provided on the side of the core package separation pressure seat 942 away from the side ear seat 904 and is slidably connected to the pressure guide rod 941. A core package separation drive component 944 is installed on the core package separation positioning seat 943. The output end of the core package separation drive component 944 is connected to the core package separation pressure seat 942. The core package separation pressure seat 942 can be pushed out by the core package separation drive component 944, so that it can flatten the starting point of the core package at the position of the guide bearing plate 93, thereby allowing it to fall smoothly and straight.
[0030] Specifically, the core package separation pressure seat 942 includes a core package separation sleeve 9421 sleeved on the pressure guide rod 941. The core package separation sleeve 9421 is locked onto a core package separation synchronization plate 9422. The side of the core package separation synchronization plate 9422 away from the guide pressure plate 93 is connected to the core package separation drive member 944. The side of the core package separation synchronization plate 9422 close to the guide pressure plate 93 is locked with a core package separation pressure plate 9423 adapted to the guide pressure plate 93. The core package separation pressure plate 9423 adapted to the guide pressure plate 93 can completely cover the core package, thereby ensuring that the entire surface of the core package can be flattened.
[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
