Abstract
Description
Technical Field
[0001] This utility model relates to a battery disassembly device, and more particularly to an upper guide separation device for electrode separation. Background Technology
[0002] Refined dismantling of individual 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 plates and separators in the core pack are then efficiently separated. The separated electrode plates are then further separated into active materials and current collectors for recycling and purification. After the core pack is oriented, the outer membrane needs to be cut open, and then the positive electrode, negative electrode, and separator of the core pack are gradually separated.
[0003] Existing electrode separation equipment is mostly designed for electrodes with high dryness, where there is obvious separation between the electrode and the separator. Often, after blowing with an air knife, the layers are automatically separated, and the equipment structure and steps are relatively simple. However, in the process of separating some core packages, some electrolyte often remains in the core package, causing the electrode and the separator to stick together. Even with an air knife, it is difficult to separate the separator and the electrode, and frequent shutdowns for debugging are required, resulting in extremely low electrode separation efficiency.
[0004] Therefore, this invention aims to provide an upper guiding separation device for electrode separation, which can process core packages with moisture, so that the core package electrodes and diaphragms can be better separated and the separation efficiency is higher. Utility Model Content
[0005] This invention provides an upper guide separation device for electrode separation, which can effectively solve the above-mentioned problems.

The upper pressing guide, the starting pressing guide, the upper cleaning guide, and the electrode end guide are all connected to a linear guide frame.
[0011] As a further improvement, the linear guide frame includes a linear guide sleeve locked to the separation guide cross plate. The top of the linear guide rod is movably mounted on the inner side of the linear guide sleeve and fixed to the upper clamping guide, the starting clamping member, the upper cleaning member, and the electrode end guide.

[0017] As a further improvement, the electrode guide plate is chamfered along the direction of electrode conveying.
[0018] The beneficial effects of this utility model are:
[0019] In existing methods of separating electrodes from semi-dry core packages, the diaphragm and electrodes often stick together, making separation difficult even with air knives. This invention addresses this by employing an upper separation guide structure. First, a starting clamping component applies pressure to the beginning of the core package, creating a gap between the diaphragm and electrodes, allowing for better air knife action. Then, at the end of the separation process, the upper clamping guide and upper cleaning component apply pressure and block the end of the core package, ensuring complete separation of the negative electrode from the diaphragm and positive electrode. Throughout the separation process, the core package is guided by the electrode end guide, resulting in greater stability and improved separation efficiency. Attached Figure Description

Detailed Implementation

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.
[0028] 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.
[0029] Reference Figures 1-4 As shown, an upper guide separation device for electrode separation includes: an upper guide gantry 70, on which at least two separation guide rods 71 are fixedly connected; and an upper separation guide structure, including an upper rear peeling member 73 movably connected to the separation guide rods 71. On the side of the upper rear peeling member 73 away from the upper guide gantry 70, an upper pressing guide member 74, a starting pressing member 75, an upper cleaning member 76, and an electrode end guide member 77 are respectively provided and movably connected to the guide rods 71. An upper guide drive member 78 is provided on the upper pressing guide member 74, the starting pressing member 75, the upper cleaning member 76, and the electrode end guide member 77.
[0030] In existing methods of separating electrodes from semi-dry core packages, the diaphragm and electrodes are often stuck together, making separation difficult even with air knives. Therefore, this invention addresses this issue with an upper separation guide structure. First, the starting clamping member 75 applies pressure to the beginning of the core package, creating a gap between the diaphragm and electrodes, allowing for better air knife action. Then, at the end of the separation process, the upper clamping guide member 74 and the upper cleaning member 76 apply pressure and block the end of the core package, ensuring complete separation of the negative electrode from the diaphragm and positive electrode. Furthermore, throughout the separation process, the core package is guided by the electrode end guide member 77, ensuring greater stability and improved separation efficiency.
[0031] In this embodiment, the positions of the upper post-peeling member 73, the upper pressing guide member 74, the starting pressing member 75, the upper cleaning member 76, and the electrode end guide member 77 on the separation guide rod 71 are all manually adjusted according to the size of the core package being processed. In other embodiments, electric adjustment can also be used, which is more precise, but it will increase the cost of the equipment.
[0032] In the later stages of core-packet separation, the negative electrode needs to be completely separated from the positive electrode and the separator. However, some of the tail of the negative electrode may be carried to the front end. Therefore, the upper post-stripping member 73 in this embodiment includes a first movable sleeve 731 that is slidably connected to the separation guide rod 71. The first movable sleeve 731 is movably connected to the separation guide rod 71 through a locking member. The lower ends of the two first movable sleeves 731 are connected to an upper stripping frame 732. The inner side of the upper stripping frame 732 is connected to an upper stripping air knife 733. The tapered upper stripping air knife 733 can generate blowing force while also providing a certain amount of pressure resistance, so that the separation effect of the end negative electrode is better.
[0033] During the core package feeding process, the upper clamping guide 74, the starting clamping member 75, the upper cleaning member 76, and the electrode end guide 77 need to make way for the core package feeding structure. After feeding is completed, the upper clamping guide 74, the starting clamping member 75, the upper cleaning member 76, and the electrode end guide 77 need to be lowered in height to contact the core package via the upper guide drive 78. Therefore, the upper guide drive 78 in this embodiment includes two second movable sleeves 781 sleeved on the separation guide rod 71. A separation guide cross plate 782 is locked between 781. A guide separation drive component 783 is locked on the separation guide cross plate 782. The guide separation drive component 783 at different positions is connected to the upper pressing guide component 74, the starting pressing component 75, the upper cleaning component 76, and the electrode end guide component 77, respectively. The upper pressing guide component 74, the starting pressing component 75, the upper cleaning component 76, and the electrode end guide component 77 are all connected to a linear guide frame 784, which can realize the change of vertical position to adapt to different working conditions.
[0034] To ensure greater stability of the upper clamping guide 74, the starting clamping member 75, the upper cleaning member 76, and the electrode end guide 77 during their vertical movement, the linear guide frame 784 includes a linear guide sleeve 7841 locked onto the separation guide cross plate 782. The inner side of the linear guide sleeve 7841 is movably mounted with linear guide rods 7842, the tops of which extend and are fixed to the upper clamping guide 74, the starting clamping member 75, the upper cleaning member 76, and the electrode end guide 77. The tops of both linear guide rods 7842 are connected to a non-circular synchronous moving plate 7843, wherein the middle of the non-circular synchronous moving plate 7843 is concave towards one side of the guide separation drive member 783, thus enhancing stability.
[0035] During the pressing process of the upper pressing guide 74, there is no need to adjust its height. Therefore, in this embodiment, the lower end of the upper pressing guide 74 is provided with an upper pressing guide frame 741 that is connected to the bottom output end of the guide separation drive 783. The two ends of the top surface of the upper pressing guide frame 741 are connected to the linear guide rod 7842. An upper pressing guide roller 742 is provided on the inner side of the upper pressing guide frame 741, and the upper pressing guide roller 742 applies pressure to the electrode sheet.
[0036] When the electrode clamping structure clamps the electrode close together, the starting clamping member 75 includes a starting connecting plate 751 connected to the linear guide rod 7842 and the guide separation drive member 783. The lower end of the starting connecting plate 751 is connected to a pressure cone plate 752. The pressure cone plate 752 applies pressure to the starting position of the diaphragm, so that the folded diaphragm can be slightly raised, thereby allowing the air knife to have a cutting entry.
[0037] If a portion of the negative electrode at the end does not completely fall into its recycling position, in this embodiment, the upper cleaning component 76 includes an upper cleaning guide frame 761 connected to the linear guide rod 7842 and the guide separation drive component 783. A cleaning air knife 762 is locked inside the upper cleaning component 76. The cleaning air knife 762 can blow the negative electrode that has not been completely recycled into its recycling end, thereby realizing the cleaning action of the negative electrode.
[0038] Due to the interference of the electrode material structure and the upper clamping guide 74, the starting clamping member 75, the upper cleaning member 76, and the electrode end guide 77, the electrode may become skewed, affecting the recycling effect. Therefore, the electrode end guide 77 in this embodiment includes an electrode guide seat 771 disposed at the lower end of the linear guide rod 7842 and the guide separation drive member 783. A U-shaped seat 772 is disposed at the lower end of the electrode guide seat 771. The electrode moves to the next station through the U-shaped seat 772, and the U-shaped seat 772 is used to regulate the transmission direction of the electrode.
[0039] To facilitate feeding, the U-shaped seat 772 includes an upper hollow hopper 7721 connected to the electrode guide seat 771. The lower end of the upper hollow hopper 7721 is connected to two electrode guide plates 7722. The electrode guide plates 7722 are chamfered along the direction of electrode conveying, thereby guiding the direction of electrode conveying.
[0040] 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, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
