Description

Technical Field

[0001] This utility model relates to the field of battery module terminal addressing technology, and in particular to a device compatible with both blade and prismatic battery module terminal addressing. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage, prismatic battery modules and blade battery modules have become the mainstream module forms. Prismatic modules are suitable for energy storage and some passenger vehicles due to their regular structure, while blade modules are suitable for electric vehicle chassis due to their thin and long dimensions. The precise positioning of the terminal post directly affects the subsequent welding quality and the stability of the module's electrical connection. The terminal post addressing equipment is the core equipment of the module production line.

[0003] Currently, most of the terminal block addressing equipment in the industry is specialized, only compatible with a single type of battery module. For example, addressing equipment for prismatic battery modules only accommodates layouts where the terminal block is located on the top surface of the module; addressing equipment for blade battery modules only accommodates structures where the terminal block is located on both sides of the module's elongated shape. When production lines need to be redesigned based on market demands, existing specialized equipment lacks compatibility because it cannot adapt to the different terminal block layouts of different modules. Companies must purchase new addressing equipment, which not only significantly increases equipment investment costs but also requires downtime for debugging the new equipment, leading to production line interruptions and reduced output. This makes it difficult to meet the actual needs of flexible and efficient module production line redesign. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device that is compatible with both blade and prismatic battery module terminal addressing, aiming to improve the current problems in the industry where terminal addressing devices are incompatible with both blade and prismatic modules, have high changeover costs, and are prone to production line interruptions.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a device compatible with blade and square-shell battery module terminal addressing, comprising a device frame body, wherein Y-axis synchronous belt module assemblies are fixedly installed at both ends of the device frame body along the Y-axis direction, and an X-axis dual-actuator linear motor assembly is fixedly installed at one end of the device frame body along the X-axis direction. A Y-axis drive motor is fixedly installed on the side of the device frame body near the X-axis dual-actuator linear motor assembly. The Y-axis drive motor synchronously drives the Y-axis synchronous belts at both ends to rotate through a transmission shaft, thereby driving the X-axis dual-actuator linear motor... The linear motor assembly moves along the Y-axis. Two sets of Z-axis rack and pinion motion assemblies are arranged inside the X-axis dual-actuator linear motor assembly. An addressing camera module assembly is fixedly mounted at the end of any one of the Z-axis rack and pinion motion assemblies. The addressing camera module assembly includes a mounting plate, which is fixedly mounted at the end of the Z-axis rack and pinion motion assembly. A rotating shaft is rotatably mounted inside the mounting plate, and a rotating plate is fixedly mounted on the rotating shaft. A rotary servo motor is fixedly connected to the rotating shaft via a coupling. A 2D vision camera and a line-scan laser rangefinder are fixedly mounted on the rotating plate.

[0006] Preferably, the addressing camera module assembly moves along the Z-axis via the Z-axis gear and rack motion assembly, the Z-axis gear and rack motion assembly moves along the X-axis via the X-axis dual-actuator linear motor assembly, and the X-axis dual-actuator linear motor assembly moves along the Y-axis via the Y-axis synchronous belt module assembly.

[0007] Preferably, the linear motor of the X-axis dual-moving linear motor assembly has two moving parts that move along the X-axis. A moving part mounting plate is fixedly installed on the inner side of any moving part, and any Z-axis gear and rack motion assembly is fixedly installed on the inner side of the corresponding moving part mounting plate. A slider connecting plate is fixedly installed on the outer side of the moving part mounting plate, and the slider connecting plate is slidably connected to the slide rail provided on the X-axis dual-moving linear motor assembly through a slider.

[0008] Preferably, the Z-axis gear and rack motion assembly includes a Z-axis motor support fixedly installed inside the mover mounting plate, a Z-axis servo motor fixedly installed inside the Z-axis motor support, a rack mounting plate slidably installed on the mover mounting plate via a guide rail, a gear and rack assembly fixedly installed on the rack mounting plate, and the Z-axis servo motor driving the rack mounting plate to move up and down via a drive gear.

[0009] Preferably, a cable carrier mounting plate is fixedly installed on the upper end of the slider connecting plate, and an X-axis cable carrier for cable routing is fixedly installed on the upper end of the cable carrier mounting plate. A Y-axis cable carrier and a Z-axis cable carrier for cable routing are respectively fixedly installed on the Y-axis synchronous belt module assembly and the Z-axis gear rack motion assembly.

[0010] Preferably, the 2D vision camera, laser rangefinder, and motors of each component are all connected to an external controller via cables.

[0011] Preferably, the two sets of Z-axis gear rack motion components move independently along the X-axis double-acting linear motor assembly via an external controller.

[0012] Preferably, the two sets of 2D vision cameras and laser rangefinders are independently rotated around the rotation axis by an external controller and a rotary servo motor. The two sets of 2D vision cameras can simultaneously detect the pole posts on both sides of the blade module and the pole posts on the top surface of the square shell module, improving addressing efficiency. Their independent movement can flexibly adapt to the differences in pole post arrangement of different modules, adjust the spacing to align with the pole posts, and avoid detection blind spots.

[0013] Preferably, a light source assembly is fixedly installed on the outer side of the lens of the 2D vision camera, which can provide stable and controllable illumination, eliminate ambient light interference, highlight the pole features, and adapt to different shooting postures such as horizontal downward and vertical side shooting, providing a clear image basis for the 2D vision camera to accurately identify the pole.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through a reasonable layout of the frame body and X-axis, Y-axis, and Z-axis motion components, and by integrating a rotary servo motor, coupling, and rotary shaft structure into the addressing camera module, can accurately adapt to the differences in the pole layout of two modules. When handling the square-shell battery module with poles located on the top surface, the addressing camera module maintains a horizontal downward posture, and is moved above the pole by the multi-axis components, with its height finely adjusted to complete the top pole positioning. When switching to the blade battery module with poles located on both sides of the long strip, the rotary servo motor drives the rotary shaft to rotate through the coupling, causing the 2D vision camera and laser rangefinder to synchronously rotate to a vertical side-viewing posture. Then, in conjunction with the multi-axis components, the relative position with the side poles is adjusted to achieve side pole addressing. The entire posture switching is automatically completed by servo control, without the need to disassemble the equipment or purchase additional special equipment, significantly reducing equipment costs, while avoiding downtime during model changes and ensuring continuous production line operation.

[0016] 2. In this utility model, the two sets of Z-axis components can move independently along the X-axis, and the cameras and rangefinders of the two camera modules can also rotate independently. This not only enables synchronous addressing of poles in different areas of the module to improve efficiency, but also adapts to different pole arrangement densities. The drag chain design of each moving component can neatly store cables, avoiding wear and extending the equipment's lifespan. The light source component on the outside of the camera optimizes image quality, and combined with the precise ranging of the laser rangefinder, further improves the pole positioning accuracy. Moreover, all components and detection parts are linked through the controller to achieve fully automated addressing, reducing manual intervention and operational errors, and better meeting the flexible and high-precision production needs of the module production line.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-12 This utility model provides an embodiment of a device compatible with addressing the terminal posts of blade and square battery module, comprising a device frame body 1, with Y-axis synchronous belt module assemblies 2 fixedly installed at both ends of the device frame body 1 along the Y-axis direction, and an X-axis dual-actuator linear motor assembly 3 fixedly installed at one end of the device frame body 1 along the X-axis direction. A Y-axis drive motor 6 is fixedly installed on the side of the device frame body 1 near the X-axis dual-actuator linear motor assembly 3. The Y-axis drive motor 6 synchronously drives the Y-axis synchronous belts at both ends to rotate through a transmission shaft, thereby driving the X-axis dual-actuator linear motor assembly 3 to move along the Y-axis. Two sets of Z-axis gear rack motion assemblies 4 are provided inside the X-axis dual-actuator linear motor assembly 3, and an addressing camera module assembly 5 is fixedly installed at the end of any Z-axis gear rack motion assembly 4.

[0033] The addressing camera module assembly 5 includes a mounting plate 5-4, which is fixedly mounted on the end of the Z-axis gear rack motion assembly 4. A rotating shaft 5-3 is rotatably mounted inside the mounting plate 5-4. A rotating plate 5-7 is fixedly mounted on the rotating shaft 5-3. A rotary servo motor 5-1 is fixedly connected to the rotating shaft 5-3 through a coupling 5-2. A 2D vision camera 5-5 and a line scan laser rangefinder 5-6 are fixedly mounted on the rotating plate 5-7.

[0034] The addressing camera module assembly 5 moves along the Z-axis via the Z-axis gear and rack motion assembly 4. The Z-axis gear and rack motion assembly 4 moves along the X-axis via the X-axis dual-movement linear motor assembly 3. The X-axis dual-movement linear motor assembly 3 moves along the Y-axis via the Y-axis synchronous belt module assembly 2. The linear motor of the X-axis dual-movement linear motor assembly 3 has two moving parts 3-4 that move along the X-axis. A moving part mounting plate 3-3 is fixedly installed inside any moving part 3-4. Any Z-axis gear and rack motion assembly 4 is fixedly installed inside the corresponding moving part mounting plate 3-3. A slider connecting plate 3-5 is fixedly installed on the outside of the moving part mounting plate 3-3. The slider connecting plate 3-5 is slidably connected to the slide rail set on the X-axis dual-movement linear motor assembly 3 via a slider. The Z-axis gear and rack motion assembly 4 includes a Z-axis motor support 4-2 fixedly installed inside the mover mounting plate 3-3, a Z-axis servo motor 7 fixedly installed inside the Z-axis motor support 4-2, a rack mounting plate 4-3 slidably installed on the mover mounting plate 3-3 via a guide rail, a gear and rack assembly fixedly installed on the rack mounting plate 4-3, and the Z-axis servo motor 7 driving the rack mounting plate 4-3 to move up and down via a drive gear; a drag chain mounting plate 3-2 is fixedly installed on the upper end of the slider connecting plate 3-5, and an X-axis drag chain 3-1 for cable routing is fixedly installed on the upper end of the drag chain mounting plate 3-2; a Y-axis drag chain 2-1 and a Z-axis drag chain 4-1 for cable routing are fixedly installed on the Y-axis synchronous belt module assembly 2 and the Z-axis gear and rack motion assembly 4, respectively;

[0035] The 2D vision camera 5-5, laser rangefinder 5-6, and motors of each component are all connected to an external controller via cables; two sets of Z-axis gear rack motion components 4 move independently along the X-axis double-acting linear motor component 3 via an external controller; the two sets of 2D vision cameras 5-5 and laser rangefinder 5-6 rotate independently around the rotation axis 5-3 via an external controller and rotary servo motor 5-1; a light source component is fixedly installed on the outside of the lens of the 2D vision camera 5-5.

[0036] The specific implementation method is as follows: After the equipment is powered on, the external controller automatically starts the self-test program to check the smoothness of movement of the Y-axis synchronous belt module assembly 2, the X-axis double-mover linear motor assembly 3, and the Z-axis gear and rack motion assembly 4. The focus is on checking the sliding accuracy of the X-axis mover 3-4 on the X-axis assembly and the lifting response speed of the Z-axis servo motor 7 driving the rack mounting plate 4-3. Simultaneously, the cable management and extension status of the Y-axis drag chain 2-1, X-axis drag chain 3-1, and Z-axis drag chain 4-1 are checked to prevent cable tangling. The start / stop and rotation angle accuracy of the rotary servo motor 5-1 are verified, and the signal transmission of the 2D vision camera 5-5, the light source assembly, and the line-scan laser rangefinder 5-6 is confirmed to be normal. After the self-test passes, the operator inputs the type and parameters of the module to be addressed into the controller, such as the spacing of the square shell module pole array, the length of the blade module, and the range of pole height. The controller then generates the corresponding motion trajectory and camera attitude parameters accordingly.

[0037] The square-shell battery module is transported to a designated workstation inside the equipment frame 1 via the production line. The workstation positioning mechanism fixes it and sends a "module in place" signal to the controller. The controller controls the rotary servo motor 5-1 to remain stationary. At this time, the rotating plate 5-7 is in a horizontal state, the 2D vision camera 5-5 is pointing downwards, and the light source assembly is turned on to optimize the imaging of the top electrode column. Subsequently, the X-axis dual-mover linear motor assembly 3 drives two sets of movers 3-4 to move independently. The movers 3-4 drive the inner mover mounting plate 3-3 and the Z-axis gear rack motion assembly 4 to move synchronously. The X-axis distance between the two sets of addressing camera module assemblies 5 is adjusted according to the lateral spacing of the pole posts on the top surface of the square shell module. The Y-axis drive motor 6 drives the Y-axis synchronous belt module assembly 2 to rotate through the transmission shaft, causing the X-axis dual-mover linear motor assembly 3, the Z-axis gear rack motion assembly 4, and the addressing camera module assembly 5 to move closer to the initial position of the pole posts along the Y-axis. The Z-axis servo motor 7 starts and drives the rack mounting plate 4-3 to move up and down along the guide rail through the drive gear, thereby causing the addressing camera module assembly 5 to move vertically up and down along the Z-axis. The height is adjusted in combination with the real-time data of the line scan laser rangefinder 5-6, so that the 2D vision camera 5-5 is at the optimal shooting focal length. Next, the 2D vision camera 5-5 captures images of the pole posts and transmits them to the controller. The controller identifies the center coordinates of the pole posts using an algorithm, and the line-scanning laser rangefinder 5-6 simultaneously calibrates the Z-axis coordinates. After recording the coordinates, the Y-axis synchronous belt module 2 continues to move the camera along the Y-axis, repeating the steps of shooting, ranging, and positioning until all top pole posts are covered. After all pole posts are positioned, the Z-axis servo motor 7 drives the rack and pinion mounting plate 4-3 to raise and reset the camera. The X-axis mover 3-4 and the Y-axis synchronous belt module 2 respectively drive the corresponding structures back to their initial positions, waiting for the next square shell module to be loaded.

[0038] After the blade battery module is transported to the designated workstation and fixed, the controller sends independent signals to two sets of rotary servo motors 5-1. One set drives the rotary shaft 5-3 to rotate clockwise, and the other set rotates counterclockwise, so that the lenses of the two sets of 2D vision cameras 5-5 face the left and right sides of the module respectively, completing the vertical side-shooting posture switch, and the light source assembly is turned on at the same time. Next, the X-axis dual-movement linear motor assembly 3 drives the two sets of movers 3-4 to adjust the spacing, and drives the two sets of Z-axis gear rack motion assemblies 4 and the camera module to move through the mover mounting plate 3-3, so that the two cameras are aligned with the two pole posts on the sides of the module respectively; the Y-axis drive motor 6 drives the Y-axis synchronous belt module assembly 2, moving the camera along the Y-axis to approach the initial position of the pole post; the Z-axis servo motor 7 drives the rack mounting plate 4-3 to move the camera up and down along the Z-axis, and adjusts the height with the data of the line scan laser rangefinder 5-6 to align with the center of the side pole post. Subsequently, the two 2D vision cameras 5-5 simultaneously capture images of the pole pieces. The controller analyzes the images from both sides to identify the XY coordinates of the pole pieces. The line-scan laser rangefinder 5-6 calibrates the X-axis coordinates, and the Y-axis synchronous belt module assembly 2 continues to move the camera along the Y-axis. The steps of simultaneous shooting, ranging, and positioning are repeated until all pole pieces on both sides of the module are covered. After positioning is completed, the Z-axis servo motor 7 drives the camera to rise, and the rotary servo motor 5-1 drives the camera to flip back to a horizontal position. The X-axis mover 3-4 and the Y-axis synchronous belt module assembly 2 return to their initial positions, waiting for the next blade module to be loaded.

[0039] Throughout the entire operation, the external controller always links all components. The two sets of Z-axis gear rack motion components 4 can move independently via X-axis mover 3-4 to adapt to different pole column arrangement densities. The two sets of 2D vision cameras 5-5 and line scan laser rangefinders 5-6 can achieve synchronous addressing of the pole columns on both sides by rotating independently via rotary servo motor 5-1. At the same time, Y-axis drag chain 2-1, X-axis drag chain 3-1, and Z-axis drag chain 4-1 move synchronously with the corresponding components, orderly storing cables, avoiding cable wear, and ensuring continuous and stable addressing process.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
