Description

Technical Field

[0001] This utility model relates to the field of battery repair technology, specifically a CTP battery pack CCS repair device. Background Technology

[0002] With the development of new energy vehicle technology, CTP (Cell to Pack) technology has been widely used because it eliminates the traditional module frame and improves the energy density of the battery pack. The CCS (Cell Connection System) of the CTP battery pack realizes the electrical connection between the cells and the sampling lines / buses through welding. However, defects such as poor welding and desoldering are prone to occur during the welding process. If the battery pack is scrapped directly, it will significantly increase the manufacturing cost of the battery pack.

[0003] Currently, repair equipment for welding defects in power batteries is mainly designed for traditional modular battery packs. The main methods used are manual or laser removal of the solder joints. Manual removal is prone to damaging the terminals and causing battery damage, while laser removal of solder joints is more expensive.

[0004] Chinese Patent No. CN218694320U discloses a battery solder joint removal device, including a worktable with a pair of guide rails arranged along the front-back direction. A placement plate is slidably mounted on the guide rails. A limiting plate one is installed at the front end of the top plate of the placement plate, and a limiting plate two is fixedly connected along the front-back direction at the right edge of the top plate of the placement plate behind the limiting plate one. A motor is installed inside the worktable on the right side of the placement plate, with the motor output end extending out of the worktable and a cutting tool for removing solder joints installed at the end. This utility model has a simple structure and reasonable design. Through this device, multiple batteries can be placed on the placement plate at one time. An electric cylinder one fixes the batteries on the placement plate, and an electric cylinder two drives the placement plate to move towards the cutting tool. The motor drives the cutting tool to rotate, cutting the solder joints off the batteries. This not only improves work efficiency but also makes the device easy to operate and inexpensive, helping companies save costs. However, the above-mentioned device removes solder joints by rotating the cutting tool with a motor, and the milling depth depends entirely on manual experience or mechanical limits, which can easily damage the batteries. Therefore, it is urgent for those skilled in the art to solve the above-mentioned technical problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned prior art, improve the efficiency of removing battery pack solder joints, and avoid damaging the battery pack terminals.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A CTP battery pack CCS rework equipment for removing solder joints from CTP battery packs includes a work carriage, a support, a displacement assembly, and a milling device.

[0008] The bracket is fixedly installed above the worktable, the displacement component is mounted on the bracket, and the milling device is connected to the displacement component;

[0009] The displacement component is used to drive the milling device to move along the X-axis and Y-axis directions. The milling device is equipped with a pressing cylinder, which is used to drive the milling device to move along the Z-axis direction.

[0010] By adopting the above technical solution, the assembly relationship between the worktable, support, displacement component, and milling device is as follows: the worktable serves as the basic load-bearing platform, the support provides a stable mounting base for the displacement component, and the displacement component drives the milling device to move laterally and longitudinally via the X / Y axes, while the downward-pressing cylinder drives the milling device to move vertically along the Z-axis. This structure enables the milling device to cover the solder joints at different locations on the CTP battery pack, achieving precise positioning in three-dimensional space and providing a basic motion control framework for solder joint removal.

[0011] Furthermore, the displacement assembly includes an X-axis lead screw, a Y-axis lead screw, and the downward pressing cylinder;

[0012] The X-axis lead screw is horizontally mounted on the bracket via a bearing seat, the Y-axis lead screw is vertically mounted on the X-axis lead screw and slidably connected to the X-axis lead screw, and the milling device is mounted on the Y-axis lead screw and slidably connected to the Y-axis lead screw;

[0013] The downward pressure cylinder is fixedly installed on the top of the milling device.

[0014] By adopting the above technical solution, the X-axis lead screw is horizontally mounted on the bracket via a bearing seat, the Y-axis lead screw is vertically slidably connected to the X-axis lead screw, the milling device is slidably connected to the Y-axis lead screw, and the downward pressure cylinder is fixed to the top of the milling device. The X-axis lead screw provides a lateral movement path for the Y-axis lead screw, the Y-axis lead screw provides longitudinal movement support for the milling device, and the downward pressure cylinder directly drives the milling device to move vertically. This structure ensures the accuracy and smoothness of X / Y axis movement through the stability of the lead screw drive, and, combined with the vertical drive of the downward pressure cylinder, enables the milling device to flexibly and stably reach the target welding point position.

[0015] Furthermore, the milling device includes a mounting bracket, a mounting plate, a probe, a milling motor, a milling cutter, and a dust extraction hood;

[0016] The mounting bracket is slidably connected to the Y-axis lead screw, and a slide rail is provided in the vertical direction of the mounting bracket. The mounting plate is slidably mounted on the slide rail by a slider.

[0017] The milling motor is fixedly mounted on the mounting plate, and the telescopic end of the downward pressing cylinder is fixedly connected to the top of the mounting plate;

[0018] The milling cutter is mounted on the power output end of the milling motor;

[0019] The probe is fixedly installed on the front end of the mounting plate; the dust collection hood is placed on the outside of the milling motor and fixedly connected to the mounting plate.

[0020] By adopting the above technical solution, the mounting bracket is slidably connected to the Y-axis lead screw. The mounting plate can be slidably installed in the vertical direction of the mounting bracket via a slide rail and a slider. The milling motor is fixed to the mounting plate. The telescopic end of the downward pressure cylinder is connected to the top of the mounting plate. The probe is fixed to the front end of the mounting plate. The dust collection hood covers the milling motor and is fixed to the mounting plate. The mounting plate slides on the mounting bracket via the slide rail and slider to ensure smoother vertical movement when the downward pressure cylinder is driven. The milling motor is fixed to the mounting plate, so that the power output of the milling cutter is synchronized with the position adjustment of the mounting plate. The probe moves with the mounting plate, which is convenient for real-time detection of the weld point position. The dust collection hood is fixed to the mounting plate and can move synchronously with the milling cutter to effectively collect the metal chips generated during milling and avoid chip splashing and contaminating the battery pack.

[0021] Furthermore, each end of the X-axis lead screw and the Y-axis lead screw is provided with an adjusting handwheel, and the adjusting handwheel is fixedly connected to the end of the lead screw.

[0022] By adopting the above technical solution, the X-axis and Y-axis lead screws are equipped with adjusting handwheels at both ends and fixed to the ends of the lead screws, providing a direct operating interface for X / Y axis position adjustment: by manually rotating the adjusting handwheels, the rotation amount of the lead screws can be precisely controlled, thereby adjusting the lateral position of the Y-axis lead screw on the X-axis, or the longitudinal position of the milling device on the Y-axis. This design simplifies the equipment operation process, eliminates the need for complex electric adjustment devices, and improves the flexibility of the equipment and the convenience of on-site adjustments.

[0023] Furthermore, the work trolley includes a work plate, guide rails, pads, and handles; the guide rails are horizontally mounted on the upper surface of the work plate for positioning the CTP battery pack; the pads are disposed on the top of the work plate for supporting the bottom of the battery pack; and the handles are symmetrically fixed to the two end faces of the work plate.

[0024] By adopting the above technical solution, the upper surface of the work plate is horizontally mounted with guide rails, the top is equipped with pads, and the two end faces are fixed with handles. The guide rails ensure the accurate placement of the CTP battery pack on the work plate through the limiting function. The pads directly support the bottom of the battery pack, avoiding deformation caused by the lack of a frame support at the bottom. The symmetrically arranged handles provide force points for the movement of the work trolley, making it easy to manually push or adjust the position of the work trolley and improving the convenience of operation.

[0025] Furthermore, the bottom of the work trolley is equipped with rollers and a ground brake, and the ground brake is fixed to both sides of the bottom of the work trolley by bolts;

[0026] The inner side of the worktable is provided with a guide device, and a guide pulley is installed on the guide device. The guide pulley rolls in contact with the inner side wall of the worktable.

[0027] By adopting the above technical solution, the work trolley is equipped with rollers and a ground brake at the bottom, and a guide device is installed on the inner side. The rollers allow the work trolley to move flexibly and adapt to the position requirements of different repair scenarios. After the ground brake is fixed with bolts, it can quickly lock the position of the work trolley and prevent it from sliding during operation. The guide pulley rolls and fits against the inner wall, reducing the frictional resistance when the work trolley moves, making the movement smoother and more stable, and avoiding the impact of jamming on the positioning accuracy of the battery pack.

[0028] Furthermore, a power supply cabinet and a cleaning device are respectively installed on both sides of the worktable. The power supply cabinet is electrically connected to the cleaning device, the pressure cylinder and the milling motor through wires.

[0029] By adopting the above technical solution, the power supply cabinet serves as a centralized power supply unit, providing stable power to electric components such as the cleaning device, the pressure cylinder, and the milling motor, avoiding the messy wiring caused by scattered wiring. The cleaning device is connected to the power supply cabinet through wires, and can receive control signals synchronously, so as to start the cleaning function in time after the milling operation, thereby improving the automation level and operation efficiency of the equipment.

[0030] Furthermore, a distance sensor is provided on the mounting plate, and controllers are provided on both sides of the bracket. The distance sensor and the controllers are electrically connected by wires.

[0031] A limiting plate is provided between the mounting plate and the mounting frame. The limiting plate is fixed to the bottom of the mounting frame and is used to limit the downward stroke of the mounting plate.

[0032] By adopting the above technical solution, the mounting plate is equipped with a distance sensor, and the mounting bracket is fixed at the bottom with a limiting plate. The distance sensor moves with the mounting plate, which can monitor the distance between the milling device and the battery pack in real time and feed the signal back to the controller to assist in controlling the milling depth. The limiting plate restricts the downward stroke of the mounting plate by physical blocking, preventing the milling cutter from colliding hard with the battery pack due to excessive drive of the downward cylinder, avoiding damage to the equipment or battery pack, and improving the safety and reliability of the operation.

[0033] This utility model has the following beneficial effects:

[0034] 1. This utility model achieves flexible movement of the milling device in the X, Y, and Z axes by linking the displacement component, X-axis lead screw, Y-axis lead screw, and pressing cylinder with the milling device. It can accurately cover the solder joints at different positions of the CTP battery pack, providing a stable three-dimensional motion control basis for solder joint removal.

[0035] 2. This utility model uses a combination design of guide rail positioning and pad support on the work trolley. The guide rail restricts the lateral displacement of the battery pack to ensure accurate placement, while the pad directly supports the bottom of the moduleless CTP battery pack, avoiding the problem of cell deformation caused by the lack of a bottom frame.

[0036] 3. This utility model uses a dust collection hood of the milling device to cover the outside of the milling motor and is electrically connected to the cleaning device of the work trolley. This realizes the active collection of metal chips during the milling process. The dust collection hood moves synchronously with the milling cutter and the automatic cleaning device for residual chips starts synchronously, effectively preventing chips from splashing and contaminating the battery cell or sampling line.

[0037] 4. This utility model forms a dual protection mechanism of real-time monitoring and physical limitation by electrically connecting the distance sensor on the mounting plate to the bracket controller and combining it with the limitation of the sliding stroke of the mounting plate by the bottom limiting plate of the mounting bracket. This ensures that the milling depth is controllable and avoids the problem of damage to the battery pack terminals caused by excessive milling. Attached Figure Description

[0046] Reference Figure 1 , Figure 2 and Figure 3 As can be seen, this utility model discloses a CTP battery pack CCS repair equipment. A worktable trolley 1 serves as the basic support platform, with a bracket 2 fixedly mounted on its top. A displacement assembly 3 is installed on the bracket 2. The displacement assembly 3 includes an X-axis lead screw 31 horizontally mounted on the bracket 2, fixed via a bearing seat, and a Y-axis lead screw 32 vertically slidably connected to the X-axis lead screw 31. A downward pressure cylinder 41 is fixedly mounted on the top of a milling device 4. The milling device 4 is slidably connected to the Y-axis lead screw 32. Its internal structure is as follows: a mounting frame 42 is slidably connected to the Y-axis lead screw 32; a vertical slide rail 421 is provided on the mounting frame 42; a mounting plate 43 is slidably mounted on the slide rail 421 via a slider; a milling motor 45 is fixed to the mounting plate 43, and a milling cutter 46 is mounted on its power output end; the telescopic end of the downward pressure cylinder 41 is fixedly connected to the top of the mounting plate 43, driving the mounting plate 43 to slide up and down along the slide rail 421; a probe 44 is fixed to the front end of the mounting plate 43, and a dust collection cover 4 is installed on its outer side. 7. The X-axis lead screw 31 and the Y-axis lead screw 32 are fixedly connected to the two ends of the adjustment handwheel 33 for manual adjustment of the lead screw position. The upper surface of the work plate 11 of the work carriage 1 is horizontally mounted with guide rail 12 for positioning the CTP battery pack. The top is set with pad block 13 to support the bottom of the battery pack. The two ends are symmetrically fixed with handles 14. Rollers 15 are installed at the bottom of the work carriage 1. The bottom sides are fixed with ground brakes 16 by bolts. The inner side of the work carriage 1 is set with guide device 17. The guide pulley 171 on the guide device 17 rolls and fits against the inner side wall. The two sides of the work carriage 1 are respectively set with power supply cabinet 5 and cleaning device 6. The power supply cabinet 5 is electrically connected to the cleaning device 6, the pressing cylinder 41 and the milling motor 45 through wires to provide power support. The mounting plate 43 is set with distance sensor 48, which is electrically connected to the controller 21 on both sides of the bracket 2 through wires. The bottom of the mounting frame 42 is fixed with limit plate 49 to limit the downward stroke of the mounting plate 43.

[0047] In one embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4It can be seen that when the battery pack solder joints are punched, the X-axis lead screw 31 is horizontally fixed to the bracket 2 via the bearing seat, and the Y-axis lead screw 32 is vertically slidably connected to the X-axis lead screw 31. When the adjusting handwheels 33 at both ends of the X-axis lead screw 31 are rotated to drive the lead screw to rotate, the Y-axis lead screw 32 slides along the X-axis direction with the lead screw, thereby driving the milling device 4, which is slidably connected to it, to move laterally as a whole, realizing the X-axis position adjustment; in the Y-axis direction, the mounting bracket 42 of the milling device 4 is slidably connected to the Y-axis lead screw 32. By rotating the adjusting handwheels 33 at both ends of the Y-axis lead screw 32 to drive the lead screw to rotate, the milling device 4 can slide longitudinally along the Y-axis lead screw 32 to achieve fine adjustment. At the same time, the rollers at the bottom of the worktable 1... Wheel 15, guide pulley 171 of inner guide device 17, and handles 14 on both sides allow the entire work trolley to be flexibly pushed along the Y-axis, assisting in adjusting the relative position of the battery pack and the milling device, and expanding the Y-axis coverage area. In the Z-axis direction, the mounting bracket 42 of the milling device 4 is vertically equipped with a slide rail 421. The mounting plate 43 is slidably mounted on the slide rail 421 via a slider. The telescopic end of the pressing cylinder 41 is fixedly connected to the top of the mounting plate 43. When the pressing cylinder 41 is activated, it drives the mounting plate 43 to slide up and down along the slide rail 421, driving the milling motor 45 and the milling cutter 46 fixed on the mounting plate 43 to move synchronously along the Z-axis, ultimately enabling the milling cutter to accurately reach the height position of the battery pack solder joint. The synergistic effect of these three components enables the milling device to accurately position itself to the designated solder joint area of ​​the battery pack in three-dimensional space, completing efficient rework operations.

[0048] In one embodiment, refer to Figure 4 It is known that the rollers 15 at the bottom of the work trolley 1 provide a flexible base for movement, and the handles 14 fixed symmetrically on both ends allow the operator to push the trolley as a whole along the ground. The guide pulleys 171 on the inner guide device 17 roll and fit against the inner wall, limiting lateral deviation during movement and ensuring that it moves linearly along a preset direction, such as the Y-axis, thus improving stability and accuracy. When the target position is reached, the ground brakes 16 fixed to the bottom sides by bolts can be stepped on or pulled to lock the rollers 15, preventing accidental slippage and completing the overall position fixation. At the same time, the guide rails 12 horizontally mounted on the upper surface of the top work plate 11 can accurately position the CTP battery pack, ensuring that its relative position matches that of the milling device 4. The pads 13 on the top of the work plate 11 support the bottom of the battery pack and assist in stable positioning, preventing displacement during rework. The rollers 15 and handles 14 enable flexible movement, the guide pulleys 171 ensure the direction of movement, the ground brakes 16 lock the position, and the guide rails 12 and pads 13 assist in the precise placement of the battery pack, together forming a complete movement and positioning system.

[0049] In one embodiment, the CTP battery pack is placed on the work plate 11 of the work trolley 1. The guide rail 12 on the work plate is used to accurately position the battery pack. The pad block 13 supports the bottom of the battery pack for stable placement. The operator pushes the trolley through the handles 14 on both sides of the work trolley. The rollers 15 at the bottom provide mobility. The guide pulleys 171 on the inner guide device 17 roll against the inner wall of the trolley to limit lateral displacement, ensuring that the trolley moves in a straight line along the preset direction into the milling equipment. After it is in place, the ground brakes 16 on both sides of the bottom are stepped on to lock the rollers 15, completing the overall positioning of the trolley and keeping the battery pack relatively fixed to the milling device 4 above. Subsequently, the displacement component 3 on the bracket 2 drives the milling device 4 to move in the X, Y, and Z axis directions: by adjusting the adjustment handwheels 33 at both ends of the X-axis lead screw 31 and the Y-axis lead screw 32, the milling device is driven to slide horizontally along the X-axis and vertically along the Y-axis to directly above the target welding point; the mounting bracket 42 of the milling device 4 is slidably connected to the Y-axis lead screw 32, and the mounting plate 43 is mounted on the vertical slide rail 421 of the mounting bracket via a slider. The downward pressure cylinder 41 is fixed to the telescopic end at the top of the milling device and connected to the mounting plate 43. The cylinder telescopically drives the mounting plate to slide down along the slide rail 421, thereby driving the milling cutter 46 to move vertically along the Z-axis to control the cutting depth. During the precision milling stage, the milling motor 45 of the milling device 4 is mounted on the mounting plate 43 and drives the milling cutter 46 to rotate at high speed to mill the solder joint. During the process, the probe 44 and distance sensor 48 at the front end of the mounting plate monitor the distance between the milling cutter and the solder joint in real time. The signal is transmitted to the controller 21 on both sides of the bracket to ensure accurate positioning. The limit plate 49 at the bottom of the mounting bracket limits the downward stroke of the mounting plate 43 to prevent excessive milling and damage to the electrode post. At the same time, the dust collection hood 47 is placed on the outside of the milling motor to collect aluminum chips. The cleaning devices 6 powered by the power supply cabinet 5 on both sides of the worktable further clean up residual debris in conjunction with the vacuum cleaner to avoid metal particles contaminating the battery cell. After a single weld point is punched, the lower cylinder 41 retracts, causing the mounting plate 43 to move upwards and reset along the slide rail 421, and the milling motor 45 stops running. By adjusting the handwheel 33, the X-axis lead screw 31 and Y-axis lead screw 32 are moved again to position the milling device 4 to the next weld point to be processed. The above steps are repeated until all weld points that need to be punched are completed.

[0050] Working principle: The work trolley 1 is used to fix the position of the battery pack and drive the battery pack to move along the Y-axis; the displacement group 3 drives the milling device 4 to move along the X-axis and Y-axis directions through the adjusting handwheels 33 of the X-axis lead screw 31 and Y-axis lead screw 32; the pressing cylinder 41, together with the probe 44 and the distance sensor 48, controls the Z-axis milling depth, and at the same time, the limit plate 49 prevents the milling cutter 46 from excessively displacing and damaging the battery pack; the milling motor drives the milling cutter to work at high speed, and after the weld is removed, the debris is cleaned by the cleaning device; after a single weld is completed, the device is reset, and the operation is repeated until all welds are processed, ultimately achieving efficient and safe rework.

[0051] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
