[0018] With the continuous development of new energy technology, batteries are widely used in many fields such as photovoltaic energy storage, new energy vehicles and industrial robots. However, when recycling or maintaining batteries, it is often necessary to disassemble the battery module. There is usually an integrated busbar (Cells Contact System, CCS) in the battery module, which is used for the electrical connection structure inside the battery module to connect the battery cells in series and parallel with high voltage to realize the current collection and transmission of the battery cells, and can perform the temperature sampling and cell voltage sampling functions of the battery. On the integrated busbar, the bar sheet is closely connected to the electrode (such as the positive or negative electrode) of the battery as a current collecting belt, which effectively collects the current generated by the battery and transmits it to the external circuit. The material of the bar sheet often needs to consider conductivity and structural strength, such as using aluminum metal or copper metal, and enhancing its structural strength and corrosion resistance through welding, electroplating and other processes. Therefore, the bar sheet can be recycled when the battery module is disassembled, and the structural strength of the bar sheet itself makes it difficult to disassemble. At present, the disassembly work is mostly done by disassembly technicians using diagonal pliers. This method is time-consuming, labor-intensive and inefficient. In addition, since there may be residual electrical energy in the battery, there are certain safety risks when disassembling the busbars of the integrated busbar, which makes the disassembly work have high technical requirements for disassembly technicians. Improper operation by personnel can easily cause the battery to spark, etc. When using an electric drill for direct disassembly, it is difficult for the disassembly technician to hold the electric drill due to its high speed and lack of support points, and there are safety hazards in the operation.

[0019] Please refer to Figure 1, which shows a schematic diagram of the front structure of a battery bar disassembly machine provided in an embodiment of the present application. The battery bar disassembly machine 100 includes: a frame 110, including a first part 111 and a second part 112, the first part 111 is arranged on the upper part of the second part 112, the second part 112 is provided with a disassembly station 120, and the disassembly station 120 carries the battery; a motion device 130, which is arranged on the first part 111, and the motion device 130 includes: a first linear module 131, a second linear module 132 and a third linear module 133, wherein the first linear module 131 and the second linear module 132 are horizontally arranged on the first part 111, and the third linear module 133 is vertically arranged on the second linear module 132, and the first linear module 131 is vertically connected to the second linear module 132; the milling device 140 is arranged on the third linear module 133 and is located above the disassembly station 120; the correction unit 150 is arranged on the third linear module 133 and is arranged close to the milling device 140, and is configured to determine the position of the battery to correct the position of the milling device 140; the distance measuring unit 160 is arranged on the third linear module 133 and is arranged close to the milling device 140, and is configured to determine the distance between the milling device 140 and the battery; the milling device 140 is also configured to disassemble the battery tabs through the motion device 130 based on the distance determined by the distance measuring unit 160.

[0020] The solution of the present application manually places the battery on the disassembly station 120, and starts the battery tab disassembly machine to automatically disassemble the tabs. The motion device 130 is responsible for the movement of the milling device 140, the correction unit 150 and the distance measuring unit 160. The first linear module 131 can control the above-mentioned units or devices to move in a first direction on the horizontal plane, and the second linear module 132 can control the movement in a second direction on the horizontal plane. The first direction is perpendicular to the second direction, forming a rectangular coordinate system on the horizontal plane; the third linear module 133 can control the above-mentioned units or devices to move in a direction perpendicular to the horizontal plane, forming a spatial rectangular coordinate system with the rectangular coordinate system of the horizontal plane. Driven by the first linear module 131 and the second linear module 132 of the motion device 130, the correction unit 150 reaches above the battery, and can adjust the height distance between the correction unit 150 and the battery through the third linear module 133 to take pictures of the positions of each welding bar of the battery, and can identify specific points of the bar, such as identifying the center point of the bar welding trajectory, determine the coordinates of the point, and feed the coordinates back to the first linear module 131 and the second linear module 132, and then calibrate the milling device 140 through the motion device 130, so that the milling device 140 is located directly above the bar of the battery, which is convenient for milling the bar. The imbalance of the milling point of the bar can easily cause the bar to be unevenly stressed and fly out, causing production risks. The correction of the correction unit 150 can improve the accuracy and safety of milling. After calibration, the motion device 130 moves the distance measuring unit 160 to the point according to the determined coordinates, determines the distance between the milling device 140 and the bar through the distance measuring unit 160, and provides the distance to the third linear module 133, so that the milling device 140 can control the downward movement distance of the third linear module 133 when milling the bar, so as to avoid the milling device 140 descending too far and thus milling through the bar, causing damage to the battery cell or leakage leading to production risks, or to prevent the milling distance from being too short, resulting in failure to disassemble the bar. During milling, the first linear module 131 and the second linear module 132 of the motion device 130 cooperate to drive the milling device 140 to the coordinate point to align with the bar, and the milling device 140 is driven downward by the third linear module 133 to mill the bar, thereby completing the automatic disassembly of the battery bar.

[0023] In the solution of the present application, the battery is placed on the support plate 210 and fixed by the limit block 220 to prevent the battery from being displaced with the tab during the disassembly process. After the battery tab disassembly machine is started, the cylinder 250 drives the slider 230 to drive the support plate 210 carrying the battery to the specified disassembly position, so that the milling device 140 can align the tab for disassembly. After the disassembly is completed, the cylinder 250 drives the slider 230 to drive the support plate 210 carrying the disassembled battery out of the disassembly position.

For example, when an operating button is set, the disassembly of the battery can be quickly started. When two operating buttons are set, it can be set to start the battery bar disassembly machine when the two operating buttons are pressed at the same time to prevent accidental touch by personnel and improve the safety of equipment use.
