Description

Technical Field

[0001] This invention relates to the technical field of battery module processing, and in particular to a cell milling machine for disassembling battery modules. Background Technology

[0002] In the repair and recycling process of power battery modules, it is often necessary to remove the current-conducting busbars that connect multiple battery cells in order to recover the intact cells. One of the key steps is to mill off the solder joints between the current-conducting busbars and the battery cell terminals.

[0003] The following problems are currently prevalent in the industry:

[0004] The operation relies on manual experience, making it difficult to guarantee accuracy: Many manufacturers use general-purpose milling machines for this operation. The clamping and positioning of the battery cells and the control of the milling depth depend entirely on the operator's clamping skills and on-site operating experience. It is very easy to damage the battery cell terminals due to excessive milling, or to make it impossible to remove the guide busbars due to insufficient milling. This results in low product consistency and success rate, which is not conducive to batch recycling operations.

[0005] High equipment costs and poor flexibility: Existing automation solutions are mostly large milling machines designed for the entire battery module, which are complex in structure, occupy a large area, and are expensive. Such equipment is not suitable for small-batch, multi-variety repair and recycling scenarios. For small and medium-sized recycling companies or R&D pilot production units, the equipment investment cost is too high and the cost-effectiveness is low.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a cell milling equipment for disassembling battery modules, so as to make it more valuable for industrial use. Summary of the Invention

[0042] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0043] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0044] First embodiment of the present invention:

[0045] like Figure 1 and Figure 2The battery cell milling equipment for disassembling battery modules according to this embodiment mainly includes a frame 1, an outer cover 2, a sliding door 3, a display 4, an X-axis module assembly 5, a Y-axis module assembly 6, and a Z-axis module assembly 7.

[0046] Specifically, frame 1 is the welded frame for the entire machine, providing a support platform. Internally, it houses the electrical cabinet, main power switch, and air supply interface. An outer cover 2 is installed on frame 1, enhancing the equipment's aesthetics while providing protection for operators.

[0047] A sliding door 3 and a display 4 are installed on the outer casing 2. Personnel can load and unload materials through the sliding door 3, and the door can be closed when the equipment is running. The display 4 is mounted on the outer casing 2 via a display bracket, which is also equipped with buttons, a keyboard, and a mouse, allowing personnel to perform related operations.

[0048] An X-axis module assembly 5, a Y-axis module assembly 6, and a Z-axis module assembly 7 are installed on the frame 1 inside the outer casing 2.

[0049] like Figure 3 and Figure 4 The X-axis module assembly 5 mainly includes an X-axis module base 501 and an X-axis linear module 502; the Y-axis module assembly 6 mainly includes a Y-axis module base 601, a Y-axis linear module 602, a tooling base 605, and a clamping and positioning assembly.

[0050] The X-axis module base 501 is mounted on the frame 1. The X-axis linear module 502 mounted on the X-axis module base 501 drives the upper Y-axis module base 601 to move left and right. Two X-axis guide rail pairs 503 are also mounted on the X-axis module base 501, allowing the Y-axis module base 601 to move left and right on the lower X-axis module base 501 via the X-axis guide rail pairs 503. In addition, X-axis protective bellows covers 504 are mounted on both the left and right sides of the X-axis module base 501, and the left and right sides of the Y-axis module base 601 are respectively connected to the two X-axis protective bellows covers 504 to prevent the internal X-axis linear module 502 and X-axis guide rail pairs 503 from being contaminated.

[0051] A Y-axis linear module 602 is mounted on the Y-axis module base 601, which drives the upper tooling base 605 to move in the front-back direction. Two Y-axis guide rail pairs 603 are also mounted on the Y-axis module base 601, allowing the tooling base 605 to move back and forth on the lower Y-axis guide rail pair 603 via the Y-axis guide rail pairs 603. Furthermore, Y-axis protective bellows covers 604 are mounted on both the front and rear sides of the Y-axis module base 601, and the front and rear sides of the tooling base 605 are respectively connected to the two Y-axis protective bellows covers 604 to prevent contamination of the internal Y-axis linear module 602 and Y-axis guide rail pairs 603.

[0052] The tooling base 605 can process two battery cells 607 simultaneously. Specifically, two positioning cavities are arranged side by side along the left-right direction on the tooling base 605. A first positioning block 608 distributed along the front-back direction is installed on the tooling base 605 between the two positioning cavities. A clamping cylinder 606 distributed along the front-back direction is installed on the tooling base 605 on the side of each positioning cavity away from the first positioning block 608. A clamping cylinder 606 distributed along the left-right direction is installed on the tooling base 605 on the right side of each positioning cavity. A second positioning block 609 is installed on the tooling base 605 on the left side of each positioning cavity, which firmly fixes the battery from both the left-right and front-back directions.

[0053] like Figure 5 The Z-axis module assembly 7 mainly includes a Z-axis mounting base plate 701, a Z-axis linear module 702, an electric spindle mounting plate 703, and an electric spindle 705.

[0054] The Z-axis mounting base plate 701 is mounted on the frame 1 on one side of the X-axis module assembly 5. A Z-axis linear module 702 is mounted on the Z-axis mounting base plate 701, which drives the electric spindle mounting plate 703 to move up and down. Two Z-axis guide rail pairs 704 are mounted on the Z-axis mounting base plate 701, and the electric spindle mounting plate 703 moves up and down on the Z-axis mounting base plate 701 via the Z-axis guide rail pairs 704. In addition, Z-axis protective bellows covers 707 are mounted on both the upper and lower sides of the Z-axis mounting base plate 701, and the upper and lower sides of the electric spindle mounting plate 703 are respectively connected to the two Z-axis protective bellows covers 707 to prevent the internal Z-axis linear module 702 and Z-axis guide rail pairs 704 from being contaminated.

[0055] An electric spindle 705 is mounted on the electric spindle mounting plate 703, and a bar end mill 706 is provided at the end of the electric spindle 705. A camera 711 is also mounted on the electric spindle mounting plate 703 on one side of the electric spindle 705.

[0056] In addition, a camera protective cover 710 is provided above the camera 711 to protect the camera 711. A protective cylinder mounting bracket 708 is installed on the electric spindle mounting plate 703 above the camera protective cover 710. A protective cylinder 709 is installed on the protective cylinder mounting bracket 708. The protective cylinder 709 can drive the camera protective cover 710 below to move up and down.

[0057] Before milling, the electric spindle mounting plate 703 lowers the camera 711 (line scan camera) to the height of the battery terminal. The X-axis module assembly 5 and Y-axis module assembly 6 collect the height information of the battery terminal. After the information is collected, the protective cylinder 709 extends and lowers the camera protective cover 710 to completely cover the camera 711 and prevent milling debris from damaging the camera 711.

[0058] The electric spindle mounting plate 703 is also equipped with 25 buttons for tool changing.

[0059] A dust collection hood 712 is also installed on the Z-axis mounting base plate 701. The dust collection hood 712 is located directly below the end mill 706 and uses a dust collector to remove dust under negative pressure.

[0060] During operation, the equipment first collects pole height information by taking pictures with a camera and transmits it to the entire system. Based on the collected height information, the entire system automatically adjusts the XY axis transfer distance in real time to achieve precise milling of the pole.

[0061] Among them, the X-axis linear module 502, Y-axis linear module 602 and Z-axis linear module 702 mentioned above are all linear drive mechanisms such as motor lead screw modules.

[0062] The second embodiment of the present invention:

[0063] like Figures 1-5 As shown in the figure, this embodiment provides a cell milling machine suitable for simultaneously processing two square-shell cells for battery module disassembly.

[0064] The main body of the equipment is a welded frame 1, which houses the electrical cabinet, main power switch, and air supply interface. The frame 1 is covered by a sheet metal outer cover 2, with a sliding glass door 3 on the front that can move left and right for loading, unloading, and equipment observation. A monitor 4 with a bracket is mounted on the top of the outer cover 2, and the bracket integrates operation buttons and a keyboard and mouse interface.

[0065] The core motion mechanism inside the outer casing 2 is a three-axis Cartesian coordinate platform. The X-axis module assembly 5 is fixed to the frame 1 via its X-axis module base 501. The Y-axis module assembly 6 is mounted on the slider of the X-axis linear module 502 via its Y-axis module base 601, and is guided by two X-axis guide rail pairs 503 to achieve smooth movement in the X-axis direction (left and right). The X-axis protective bellows cover 504 is used to protect the internal mechanism.

[0066] On the Y-axis module assembly 6, the Y-axis linear module 602 drives the fixture base 605 to move in the Y-axis direction (back and forth), guided by two Y-axis guide rail pairs 603. A Y-axis protective bellows cover 604 provides protection. The fixture base 605 has two side-by-side positioning cavities. A fixed first positioning block 608 is located inside each cavity, and a clamping cylinder 606 is installed on the opposite side. A fixed second positioning block 609 is located on the other side of the cavity, and another clamping cylinder 606 is installed on the opposite side. During clamping, the battery cell 607 is placed into the cavity, pressed against the first positioning block 608 and the second positioning block 609, and then the clamping cylinders 606 on both sides are activated to firmly press the battery cell onto the positioning blocks from the front-back and left-right directions.

[0067] Z-axis module assembly 7 is fixed to one side of frame 1 via Z-axis mounting base 701. Z-axis linear module 702 drives electric spindle mounting plate 703 to move in the Z-axis direction (up and down), guided by two Z-axis guide rail pairs 704. Z-axis protective bellows cover 707 provides protection. Electric spindle 705 is mounted on electric spindle mounting plate 703, and a bar end mill 706 is mounted at its lower end. Line scan camera 711 for height measurement is fixed to the side of electric spindle mounting plate 703. A protective mechanism is provided above camera 711, including a protective cylinder mounting bracket 708 fixed on electric spindle mounting plate 703, a protective cylinder 709 mounted thereon, and a camera protective cover 710 connected to the piston rod of protective cylinder 709. Dust collection cover 712 is mounted on Z-axis mounting base 701, directly below bar end mill 706, and connected to external dust collection equipment.

[0068] The working process of this embodiment is as follows:

[0069] Preparation and clamping: The operator opens the sliding door 3, places the two battery cells 607 that need to be disassembled into the two positioning cavities of the tooling base 605, presses them against the first positioning block 608 and the second positioning block 609, and activates the clamping cylinder 606 to fix them in place. Close the sliding door 3.

[0070] Visual height measurement: Upon starting the equipment, the control system first controls the Z-axis module assembly 7 to descend, moving the camera 711 to a position slightly higher than the battery cell terminals. Then, it controls the X-axis and Y-axis module assemblies 5 and 6 to move, causing the battery cells on the fixture base 605 to move, allowing the camera 711 to scan each terminal of the two battery cells sequentially, accurately acquiring the height coordinate information of the top surface of each terminal, and transmitting it to the control system.

[0071] Camera Protection and Milling: After height measurement, the protection cylinder 709 actuates, pushing the camera protective cover 710 down to completely cover and protect the camera 711. Subsequently, the control system automatically calculates and plans the milling path and depth compensation value based on the measured pole height data. The electric spindle 705 starts, driving the end mill 706 to rotate at high speed. The three-axis platform moves in coordination, milling the weld points on each pole one by one according to the predetermined path. The dust collection hood 712 works synchronously to suck up the generated debris.

[0072] Completion and unloading: After all weld points are milled to the set depth, the equipment automatically stops, the electric spindle resets, and the protective cylinder 709 retracts the camera protective cover 710. The operator opens the door, releases the clamping cylinder 606, and removes the battery cell with the separated guide tube, completing one operation.

[0073] The control system and its working principle described above are conventional technologies in this field and will not be elaborated upon further here.

[0074] This invention achieves low-cost, high-precision, and automated milling of cell terminal solder joints through specialized structural design and visual positioning compensation, which is particularly suitable for the small-batch, high-flexibility production needs of the battery recycling industry.

[0075] The X-axis direction mentioned in this article is as follows: Figure 2 The left and right directions shown are the same as the Y-axis direction. Figure 2 The front-back direction shown in the figure, the Z-axis direction is as follows Figure 2 The vertical or up-down direction shown.

[0076] This invention relates to equipment specifically designed for the milling process of battery cell terminal solder joints. Its compact structure and low manufacturing cost compared to large general-purpose machine tools or fully automated module milling lines give it a competitive edge in the market. An integrated vision system automatically measures the height of each terminal and feeds the data back to the control system, compensating for milling depth in real time. This eliminates errors caused by manual tool setting and trial cuts, ensuring consistent milling accuracy and reducing the skill requirements for operators. The equipment is equipped with a fully enclosed enclosure, protective bellows covers for moving parts, an automatic camera protective cover, and a dust collection system, effectively ensuring operator safety and maintaining the cleanliness of the equipment's interior.
