Description

Technical Field

[0001] This utility model relates to a battery disassembly device, and more particularly to a multi-layer cell pack separation device. 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 efficiently separated. The separated electrode plates are then separated separately for active materials and current collectors for further recycling and purification. After the core pack is separated, since the number of core packs in different batteries varies, the core pack needs to be separated into single layers before recycling.

[0003] Most existing core-packet separation devices use a cutting method, where a cutting blade cuts the adhesive paper tightly binding the two core packs, allowing them to be separated. However, this method makes it difficult to control the cutting force, and excessive cutting can damage the integrity of the core packs, leading to discontinuity in the subsequent electrode separation stage, which is not conducive to electrode recycling.

[0004] Therefore, this invention aims to provide a multi-layer core pack separation device. When the core pack has a multi-layer structure, the device can puncture the side of the adhesive tape, causing the tape to split from both sides, without damaging the core pack during the separation of the multi-layer core pack. When the core pack is a single layer, the device can directly transport the core pack, thus adapting to batteries of different specifications. Utility Model Content

[0005] This invention provides a multi-layer core-packet separation device, which can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A multilayer core-packet separation device, comprising:

[0008] A core package transfer machine is provided, wherein a transfer robot arm is provided on the core package transfer machine, a core package moving frame that can move up and down is provided on the transfer robot arm, and a core package separation drive component is provided on the core package moving frame;

[0009] A core package separation assembly includes a core package limiting assembly connected to a core package separation drive member. A separating member is provided on the inner side of the core package limiting assembly. The core package separation drive member drives the core package limiting assembly to move closer to or away from the core package, causing the separating member to puncture the adhesive paper on the core package.

[0010] As a further improvement, the core package moving frame includes a robot arm connecting frame that connects to the transfer robot arm, the lower end of which is connected to a separation crossbeam, the lower end of which is connected to a core package separation drive.

[0011] As a further improvement, the core package separation drive includes a separation drive motor disposed at the upper end of the separation crossbeam. The separation drive motor passes through the separation crossbeam and is connected to a separation drive wheel located at the lower end of the separation crossbeam. The separation drive wheel is connected to a separation driven wheel via a separation timing belt. The core package limiting assembly is connected to the separation timing belt.

[0012] As a further improvement, the core package limiting assembly includes two sets of core package limiting members. Each core package limiting member includes a limiting connecting arm that is connected to the separation timing belt. The limiting connecting arm is connected to a side blocking frame, and the lower end of the side blocking frame is connected to the separation member.

[0013] As a further improvement, the separator is a serrated blade with one side of the serrations facing the battery.

[0014] As a further improvement, a top core packing clamping member is provided on the inner side of the side barrier frame. The top core packing clamping member includes a core packing top surface clamping push rod that is locked onto the side barrier frame. The lower end of the core packing top surface clamping push rod is connected to an adhesive tape clamping claw.

[0015] As a further improvement, the top core packing clamps are located on both sides of one end of the long axis of the separation crossbar, and there are a total of four top core packing clamps.

[0016] As a further improvement, the transfer robot includes a robot mounting base connected to the core package transfer machine. A first reversing motor assembly is locked onto the robot mounting base. A first robot stroke extension plate is connected to the output end of the first reversing motor assembly. A second robot stroke extension plate is movably connected to the end of the first robot stroke extension plate away from the first reversing motor assembly via a second reversing motor assembly. A core package separation push rod connected to the robot connecting frame is provided at the end of the second robot stroke extension plate away from the second reversing motor assembly.

[0017] The beneficial effects of this utility model are:

[0018] Existing multi-layer core packs are mostly cut manually or automatically, which makes it difficult to guarantee the cutting depth. If the cutting is too light, the adhesive paper will not be cut, and if it is too heavy, the inner structure of the core pack will be damaged. Therefore, this utility model has a core pack separation component. After the transfer robot moves the core pack moving frame to the position of the core pack, the core pack separation drive component moves the core pack limiting component to the middle of the two core packs. This allows the separation component to pierce the adhesive paper between the two core packs and break the adhesive paper. This allows the two core packs to be separated without damaging the core pack itself, thus improving the separation efficiency. Attached Figure Description

Detailed Implementation

[0026] 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. 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. 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.

[0027] 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.

[0028] Reference Figures 1-4 As shown, a multi-layer core-packet separation device includes: a core-packet transfer platform 60, on which a transfer robot 61 is mounted, and on which a core-packet moving frame 62 that can move up and down is mounted, and on which a core-packet separation drive component 63 is mounted; and a core-packet separation assembly 64, including a core-packet limiting assembly 641 connected to the core-packet separation drive component 63, with a separation component 642 disposed on the inner side of the core-packet limiting assembly 641, and the core-packet separation drive component 63 driving the core-packet limiting assembly 641 to move closer to or away from the core-packet, so that the separation component 642 punctures the adhesive paper on the core-packet.

[0029] In the processing of some multi-layer core packages, manual cutting or automatic cutting is often used, which makes it difficult to guarantee the cutting depth. If the cutting is too light, the adhesive paper will not be cut, and if it is too heavy, the inner structure of the core package will be easily damaged. Therefore, this utility model has a core package separation component 64. After the transfer robot 61 moves the core package moving frame 62 to the position of the core package, the core package separation drive component 63 drives the core package limiting component 641 to move towards the middle of the two core packages. This allows the separation component 642 to pierce the adhesive paper between the two core packages and break the adhesive paper. This allows the two core packages to be separated without damaging the core packages themselves, thus improving the separation efficiency.

[0030] When separating the cell packs, since the width of the cell packs of different battery specifications is different, the cell pack moving frame 62 in this embodiment includes a robot arm connecting frame 621 connected to the transfer robot arm 61. The lower end of the robot arm connecting frame 621 is connected to a separation cross frame 622. The lower end of the separation cross frame 622 is connected to the cell pack separation drive component 63. Through the wider separation cross frame 622, the cell pack limiting component 641 after width adjustment can meet the width of most cell packs on the market, thereby improving the practicality of this invention.

[0031] During the process of driving the core package separation drive 63 to drive the core package limiting component 641, since the transfer robot 61 will hover at the upper end of the core package, if the drive structure pushes out in one direction, it needs to be corrected twice. Therefore, the core package separation drive 63 in this embodiment includes a separation drive motor 631 set at the upper end of the separation crossbeam 622. The separation drive motor 631 passes through the separation crossbeam 622 and is connected to a separation drive wheel 632 located at the lower end of the separation crossbeam 622. The separation drive wheel 632 is connected to a separation driven wheel through a separation timing belt 633. The core package limiting component 641 is connected to the separation timing belt 633. By the effect of the two ends of the belt surface moving in different directions during the operation of the separation timing belt 633, the core package limiting component 641 can move towards the middle or towards both sides at the same time. Only one positioning step is needed to reach the accurate separation point. The separation drive motor 631 is a servo motor with extremely high rotational accuracy, so as to accurately control the displacement of the separation timing belt 633.

[0032] During the cooperation between the core-packing limiting assembly 641 and the separating synchronous belt 633, the core-packing limiting assembly 641 includes two sets of core-packing limiting members. Each core-packing limiting member includes a limiting connecting arm 6411 that connects to the separating synchronous belt 633. The limiting connecting arm 6411 is connected to a side blocking frame 6412. The lower end of the side blocking frame 6412 is connected to the separating member 642, thereby enabling the two side blocking frames 6412 to move synchronously during the movement of the separating synchronous belt 633.

[0033] In this embodiment, the separating member 642 is a serrated blade with one side of the serration facing the battery. During the process of pushing out the side blocking frame 6412, the serration can puncture the adhesive paper.

[0034] However, during the process of the separating member 642 piercing the adhesive tape, the adhesive tape may partially move, causing the contact point between the separating member 642 and the adhesive tape to sink inward. The separating member 642 cannot pierce the adhesive tape within the preset displacement distance. Therefore, in this embodiment, a top core packing clamping member 643 is provided on the inner side of the side barrier frame 6412. The top core packing clamping member 643 includes a core packing top surface clamping push rod 6431 locked on the side barrier frame 6412. The lower end of the core packing top surface clamping push rod 6431 is connected to an adhesive tape clamping claw 6432. The adhesive tape on the top surface is fixed by the adhesive tape clamping claw 6432, so that the adhesive tape has sufficient tension when the separating member 642 contacts the adhesive tape, making it easier to pierce.

[0035] To balance the tension, in this embodiment, the top core packing clamping member 643 is located on both sides of one end of the long axis of the separating crossbar 622. There are four top core packing clamping members 643 in total. The even arrangement makes it easier for the long strip separating member 642 to separate the adhesive paper.

[0036] Different specifications of cell packs have different heights and widths. Therefore, before processing batteries of the same batch, preset data needs to be input to ensure that the transfer robot 61 reaches the accurate separation point. In this embodiment, the transfer robot 61 includes a robot mounting base 611 connected to the cell pack transfer machine 60. A first commutator motor assembly 612 is locked onto the robot mounting base 611. A first robot stroke extension plate 613 is connected to the output end of the first commutator motor assembly 612. The first robot stroke extension plate 613 is located away from the first commutator motor assembly 612. One end of 12 is movably connected to a second manipulator stroke extension plate 615 via a second commutator motor assembly 614. The end of the second manipulator stroke extension plate 615 away from the second commutator motor assembly 614 is provided with a core pack separation push rod 616 that connects to the manipulator connecting frame 621. By combining the first commutator motor assembly 612 and the second commutator motor assembly 614 with the first manipulator stroke extension plate 613 and the second manipulator stroke extension plate 615, the manipulator connecting frame 621 can reach the accurate position. Both large and small core packs are within the stroke range of the transfer manipulator 61.

[0037] 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.
