[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0041] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," and "back" appear, they are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, if terms such as "first" and "second" appear, they are used solely for descriptive purposes and should not be construed as indicating or implying relative importance.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] This embodiment relates to an auxiliary tool for battery disassembly, which comprises a first disassembly platform 1 and a first disassembly tool. The first disassembly platform 1 is provided with a clamping portion for positioning a battery module 100 to be disassembled on the first disassembly platform 1.

[0044] The first disassembly tool includes a first winding rod 9, which can be detachably connected to the first manipulator and move with the first manipulator to retract the side panel of the battery module 100; and / or, the first disassembly tool includes a separation plate 7, which can be detachably connected to the first manipulator and move with the first manipulator to separate the end plate and battery cell 200 of the battery module 100, as well as two adjacent battery cells 200.

[0045] The auxiliary tooling for battery disassembly described in this embodiment positions the battery module 100 to be disassembled on the first disassembly table 1 through the clamping part, and can be connected to the first winding rod 9 through the first manipulator, so that after the end plate and the side plate are separated, the side plate can be rolled up by the first winding rod 9, thereby helping to improve the disassembly efficiency of the side plate. The end plate and the battery cell 200, as well as the two adjacent battery cells 200 can also be separated by the separation plate 7, which has better safety than the solution of manually removing the battery module 100.

[0046] Based on the above overall introduction, an exemplary structure of the auxiliary tooling for battery disassembly in this embodiment is as follows: Figure 1 and Figure 2 As shown in . Among them, the structure of the first disassembly station 1 is as follows Figure 3 As shown in FIG, the clamping unit includes a plurality of clamping plates 101 rotatably disposed on opposite sides of the first disassembly station 1, and a first driving unit for driving each clamping plate 101 to rotate. The provision of the first driving unit facilitates driving the clamping plates 101 to rotate individually, thereby facilitating changing the working state of the clamping plates 101.

[0047] As a feasible embodiment, two spaced-apart clamping plates 101 are provided on either side of the first disassembly platform 1 in the width direction. The bottom end of each clamping plate 101 is rotatably mounted on the first disassembly platform 1. The first drive unit can be a motor disposed within the first disassembly platform 1, which has a simple structure and is easy to arrange and implement. When a battery module 100 to be disassembled is required, each first drive unit drives the corresponding clamping plate 101 to rotate outward. After the battery module 100 is placed in place, the first drive unit drives the corresponding clamping plate 101 to rotate inward and abut against the side panel of the battery module 100, thereby positioning the battery module 100 on the first disassembly platform 1.

[0048] It is understandable that the number of clamping plates 101 can be determined according to usage requirements, as long as the battery module 100 can be clamped and positioned. In addition, to further improve the positioning effect of the battery module 100 on the first disassembly platform 1, a plurality of spaced adsorption holes can be provided on the top of the first disassembly platform 1. The adsorption holes can be connected to an external vacuum device to adsorb the bottom surface of the battery module 100, thereby improving the positioning effect of the battery module 100 on the first disassembly platform 1 and enhancing the stability of the battery module 100 during disassembly.

[0049] The first disassembly tool includes a first winding rod 9 and a separation plate 7, which is conducive to improving the performance of the auxiliary tool. Figure 3 As shown in the figure, the first winding rod 9 comprises a main portion 901 and multiple rod portions 902 spaced apart from the main portion 901. The main portion 901 is detachably connected to the first manipulator. The arrangement of the main portion 901 and the rod portions 902 improves the winding effect. Specifically, the main portion 901 is block-shaped, and the multiple rod portions 902 are connected to the bottom of the main portion 901 and extend downward. For example, there are two rod portions 902, but the number of rod portions 902 can be increased according to usage requirements.

[0050] In the battery module 100 located on the first disassembly station 1 in this embodiment, the two ends of the side panels and the connection points of the corresponding end panels have been separated in advance, so that the first winding rod 9 can wind the side panels, thereby separating the side panels from the battery module 100.

[0051] To disassemble and separate the side panels, one end of the side panel is first connected (e.g., bonded) to the two rod portions 902. The first robotic arm then moves along the length of the side panel while also rotating the first winding rod 9, thereby winding the side panel onto the first winding rod 9. When the first winding rod 9 reaches the clamping plate 101, the corresponding first drive unit rotates the clamping plate 101 outward until the first winding rod 9 completes winding the side panel at that location. At this point, the first drive unit then resets the clamping plate 101.

[0052] As a preferred embodiment, the first manipulator in this embodiment can adopt a full-freedom manipulator in the prior art, so that the first manipulator can drive the first winding rod 9 to rotate while also moving along the length direction of the battery module 100, thereby realizing the winding and disassembly of the side panels. To facilitate the installation of the first manipulator, as shown in FIG. Figure 1 As shown in FIG, a first mounting base 1201 is provided above the first disassembling station 1, and the top end of the first manipulator is specifically mounted on the first mounting base 1201. The first mounting base 1201 can be fixed to the frame 12, and a rotating head is rotatably provided at the bottom end of the first manipulator, and the main portion 901 of the first winding rod 9 is specifically detachably connected to the rotating head.

[0053] In terms of specific structure, a connection groove with an opening facing downward is provided on the rotating head, and a through-hole is provided on the wall of the connection groove. A clamping head 13 is provided on the top of the main body 901, which is arranged to slide radially, and a spring is provided between the clamping head 13 and the main body 901. During the process of inserting the top of the main body 901 into the connection groove, the clamping head 13 is squeezed and retracted into the main body 901 and compresses the spring. When the clamping head 13 slides to the clamping hole position, the clamping head 13 can slide into the clamping hole under the action of the spring, and the main body 901 and the rotating head are clamped. When the manipulator drives the rotating head to rotate, it can drive the first winding rod 9 to rotate, thereby winding the side plate. When the first winding rod 9 moves from one end of the side plate to the other end, the side plate can be completely wound and the side plate can be separated from the battery cell 200.

[0054] like Figure 4 and Figure 5 As shown in the figure, the top of the separator plate 7 in this embodiment is also provided with a clamping head 13 and a spring that engage with the clamping hole in the connection slot, thereby securing the top of the separator plate 7 to the rotating head. The first manipulator drives the separator plate 7 up and down, allowing it to be inserted between the end plate and the battery cell 200 to separate them. The first manipulator can also move the first separator plate 7 and separate two adjacent battery cells 200 by moving the separator plate 7 up and down. To ensure the performance of the separator plate 7, as shown in the figure, the bottom surface of the separator plate 7 is pointed.

[0055] As a preferred embodiment, Figure 2As shown in , the auxiliary tooling also includes a toolbox located on one side of the first disassembly platform 1. The toolbox has an open-top storage slot for accommodating the first winding rod 9 or the separator plate 7. To distinguish it from the toolbox described below, the toolbox located on the side of the first disassembly platform 1 is referred to as the first toolbox 5, and the storage slot within the first toolbox 5 is referred to as the first storage slot 501. The first toolbox 5 has two storage slots: one first storage slot 501 is for accommodating the first winding rod 9, and the other first storage slot 501 is for accommodating the separator plate 7. The provision of the first toolbox 5 facilitates storage of the first disassembly tools.

[0056] In order to facilitate the installation and removal of the first manipulator and the first winding rod 9 or the separation plate 7, as shown in FIG. Figure 6 As shown in FIG, the first tool box 5 is provided with a first stopper protrusion 502 located above one open end. The first winding rod 9 or the separation plate 7 can slide within the corresponding first receiving slot 501, with a first position where it is blocked by the stopper protrusion 502 and a second position where it is released from the stopper protrusion 502. The provision of the stopper protrusion 502 facilitates the connection and disconnection of the first manipulator and the disassembly tool, thereby facilitating the replacement of the disassembly tool.

[0057] During use, the first manipulator drives the rotating head to the top of the first winding rod 9 or separation plate 7 in the first position. The rotating head moves downward, causing the clamping head 13 to engage with the corresponding clamping hole, thereby installing the first winding rod 9 or separation plate 7 on the first manipulator. The first manipulator then drives the first winding rod 9 or separation plate 7 to the second position, and then moves up and down to remove the first winding rod 9 or separation plate 7 from the corresponding first receiving slot 501.

[0058] When the first winding rod 9 or the separating plate 7 needs to be disassembled, the first manipulator first places the first winding rod 9 or the separating plate 7 in the second position corresponding to the first receiving slot 501, moves it to the first position, and then moves the first manipulator up and down. At this time, the first winding rod 9 or the separating plate 7 is blocked by the limiting protrusion 502, so that the clamping head 13 can be disengaged from the clamping hole, thereby completing the disassembly of the first winding rod 9 or the separating plate 7. This facilitates the installation and removal of the first disassembly tool on the first manipulator. Of course, it is also feasible to install and remove the first disassembly tool only by hand.

[0059] As a preferred embodiment, Figure 1 and Figure 2As shown in , the auxiliary tooling for battery disassembly in this embodiment also includes a second disassembly station 2 and a second disassembly tool. The second disassembly station 2 is located downstream of the first disassembly station 1, and is provided with an adsorption portion, which is used to adsorb the battery cell 200 to be disassembled onto the second disassembly station 2. Among them, the second disassembly tool includes a first separation knife 11, which can be detachably connected to the second manipulator and, as the second manipulator moves, cuts open one end of the battery cell casing near the cover. And / or, the second disassembly tool includes a second separation knife, which is detachably connected to the second manipulator and, as the second manipulator moves, separates the cover plate and the electrode group.

[0060] In this embodiment, the battery cell 200 to be disassembled is positioned on the second disassembly station 2 using an adsorption portion. A second manipulator, in conjunction with the first separating blade 11, facilitates splitting the cell casing, thereby separating the cover from the cell casing. The second separating blade and the second manipulator further facilitate separation of the cover from the electrode assembly. The battery cell 200 on the second disassembly station 2 can specifically be an identified defective battery cell 200. In practice, the second separating blade can be a ceramic blade.

[0061] In this embodiment, the structure of the second disassembly platform 2 is substantially the same as that of the first disassembly platform 1 . The adsorption portion includes an adsorption chamber provided on the second disassembly platform 2 and a plurality of adsorption holes provided through the top surface of the second disassembly platform 2 . The adsorption chamber is connected to an external vacuum device to adsorb the battery cell 200 on the second disassembly platform 2 .

[0062] As a preferred embodiment, the second disassembly tool includes a first separation knife 11 and a second separation knife, which is conducive to improving the convenience of disassembly. Figure 9 As shown in , a metal knife can be used to facilitate cutting open the battery cell shell. A clamping head 13 is provided on the handle 1101 of the first separating knife 11 to connect with the second manipulator.

[0063] Further, such as Figure 7 and Figure 8 As shown in , the second disassembly tool also includes a limit plate 8 that can be attached to the side of the battery cell housing. Limit plate 8 is provided with a limit hole 801 for the blade of the second separating knife to pass through. Limit hole 801 is used to limit the depth of the second separating knife's penetration into the battery cell housing. The provision of limit plate 8 and limit hole 801 helps prevent the second separating knife from penetrating too deep, thereby improving disassembly safety.

[0064] Specifically, the bottom of the limiting plate 8 is provided with a gripping block 802, and the limiting hole 801 is a long strip located at the top of the limiting plate 8 and extending horizontally along the limiting plate 8. The structure of the second manipulator is identical to that of the first manipulator, and both can utilize fully free-end manipulators as known in the art. To facilitate the placement of the second manipulator, a second mounting base 1202 is provided above the second disassembly station 2. This second mounting base 1202 is fixed to the frame 12, and the top of the second manipulator is connected to this second mounting base 1202.

[0065] When the first separation knife 11 is needed, the first separation knife 11 is connected to the second manipulator, and the limiting plate 8 is attached to the corresponding side of the battery cell shell. The manipulator drives the first separation knife 11 to be inserted into the corresponding limiting hole 801 and moves along the length direction of the limiting hole 801, thereby cutting open the battery cell shell on one side. Then rotate the battery cell 200, and continue to cooperate with the limiting plate 8 and the first separation knife 11 to cut open the other sides of the battery cell shell, thereby separating the cover plate from the battery cell shell. During the use of the first separation knife 11 and the limiting plate 8, manual cooperation can be adopted according to the use requirements to ensure the separation effect of the cover plate and the battery cell shell.

[0066] When the second separation knife is needed, it is connected to the second manipulator, and the connection between the electrode assembly and the cover plate is arranged to correspond to the movement path of the second separation knife. As the second separation knife moves up and down, the cover plate can be separated from the electrode assembly. During the use of the second separation knife, manual cooperation can also be used according to the needs to ensure the separation of the cover plate and the electrode assembly.

[0067] In addition, the second disassembly tool in this embodiment includes a second winding rod, which can be detachably connected to the second manipulator and retracts the diaphragm as the second manipulator moves. The provision of a second winding rod facilitates reeling of the diaphragm and improves the safety of disassembling the battery cell 200. Specifically, the structure of the second winding rod is identical to that of the first winding rod 9 and will not be further described here. Here, the connection between the first and second separation blades 11 and the second winding rod and the second manipulator can also adopt a clamping structure in which a clamping hole and a clamping head 13 cooperate.

[0068] like Figure 2 As shown in FIG, a second tool box 6 may be provided on one side of the second disassembly platform 2. The second tool box 6 includes a plurality of second storage slots 601 for respectively storing the limiting plate 8, the first separating blade 11, the second separating blade, and the second winding rod. The method for removing and placing each second disassembly tool in the corresponding second storage slot 601 is the same as the method for removing and placing each first disassembly tool in the first storage slot 501, and will not be further described here.

[0069] In addition, if Figure 1 and Figure 2As shown in , the battery disassembly auxiliary tooling of this embodiment further includes a first conveyor for conveying the battery module 100 to be disassembled to the first disassembly station 1, a second conveyor disposed between the first disassembly station 1 and the second disassembly station 2, and a third conveyor for conveying the disassembled battery cells 200 on the second disassembly station 2 backward. The provision of multiple conveyor sections facilitates improved continuity in battery disassembly and improved transport convenience.

[0070] At least one of the first, second, and third conveyor sections includes a conveyor belt 3 and a plurality of conveyor rods 4 rotatably positioned downstream of the conveyor belt 3. The conveyor belt 3 and conveyor rods 4 have a simple structure, are easy to deploy, and provide efficient conveying. A fourth conveyor section may also be provided on the side of the first disassembly station 1 to transport other components of the disassembled battery module 100. Furthermore, a fifth conveyor section may also be provided on the side of the second disassembly station 2 to transport other components of the disassembled battery cell 200.

[0071] like Figure 1 As shown in , the auxiliary tooling of this embodiment also includes an image acquisition unit 10 for capturing images of the battery cells 200 on the second disassembly station 2. This facilitates capturing images of the disassembled battery cells 200. In specific implementations, the image acquisition unit 10 can employ a conventional CCD camera, which can be mounted on the second mounting base 1202 to capture images of the disassembled battery cells 200. The image acquisition unit 10 can record the appearance of the battery cells 200, the electrode assembly, the separator, and more.

[0072] The battery disassembly auxiliary tool in this embodiment, through the cooperation of a first manipulator and a first disassembly tool, can disassemble the side panels of the battery module 100, and separate the end panels from the battery cells 200, and between adjacent battery cells 200. The second manipulator and a second disassembly tool then cooperate to disassemble the cover plate from the battery cell housing, and separate the electrode assembly from the cover plate.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
