[0002] In the production and manufacturing of new energy power batteries and energy storage systems, BDU (full name: Battery Disconnection Unit) usually refers to the battery disconnection unit. As a key high-voltage electrical component inside the battery pack, it is responsible for the safe connection, disconnection and management of high-voltage circuits.
[0003] Traditional BDU manual assembly requires screw fixing. Assembly workbenches only provide the work surface and lack effective assembly support functions. Manual operation requires a high level of experience from workers. Finding the right screw in a cluttered screw storage area is time-consuming and inefficient. Furthermore, the reaction force when tightening screws with a hand screwdriver leads to high labor intensity over long periods and can cause screw misalignment, compromising assembly quality. Additionally, post-assembly inspection is necessary to detect defects, increasing production and time costs and failing to meet the requirements for efficient and precise BDU assembly.

[0011] Furthermore, the anti-torsion robotic arm also includes an auxiliary rod, which is arranged parallel to and spaced apart from the lifting guide rod, and the floating seat is slidably engaged with the auxiliary rod.
[0012] Furthermore, the BDU assembly workbench also includes a camera monitor, which is located on the side of the frame near the work surface, and is used to capture and record assembly videos and images of the BDU products.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0023] like Figure 1 , Figure 2 As shown, a BDU assembly workbench according to an embodiment of the present invention has a third direction Z and includes: a frame 1, a laser guiding mechanism 2, a vision inspection element 4, and an anti-torsion robotic arm 5; the frame 1 has a working surface 10, which is arranged facing the third direction Z, and an assembly fixture 11 is provided on the working surface 10; the laser guiding mechanism 2 is provided on the frame 1, and the laser guiding mechanism 2 is spaced apart on one side of the working surface 10 along the third direction Z, for projecting marking points toward the assembly fixture 11.
[0024] The vision inspection element 4 is located on the frame 1. The vision inspection element 4 is spaced apart on one side of the working surface 10 along the third direction Z. It is used to collect image information during the assembly of BDU product 14. The anti-torsion robotic arm 5 is located on the frame 1. The anti-torsion robotic arm 5 has a screw gun mounting seat 50. The screw gun mounting seat 50 is spaced apart on one side of the working surface 10 along the third direction Z. It is used to counteract the reaction force during tightening.
[0025] The BDU assembly workbench adopts a design consisting of a frame 1, a laser guidance mechanism 2, a vision inspection element 4, and an anti-torsion robotic arm 5. The frame 1 has a working surface 10, and the laser guidance mechanism 2 and the vision inspection element 4 are spaced apart along the third direction Z on one side of the working surface 10. The laser guidance mechanism 2 can project and mark points on the assembly fixture 11, providing workers with intuitive guidance on screw installation positions, making it easy for workers to accurately and quickly place screws at the marked points.
[0026] The visual inspection element 4 can collect image information in real time during the assembly process of BDU product 14. It analyzes the screw installation status and component connection status through image processing algorithms, and promptly detects problems such as missing screws, improper installation, and component misalignment. Finally, the inspection results are fed back to the operator or production control system to facilitate timely correction of assembly errors.
[0027] The anti-torsion robotic arm 5 is mounted on the frame 1. The screw gun mounting base 50 of the anti-torsion robotic arm 5 is arranged at Z intervals along the third direction on one side of the working surface 10. The anti-torsion robotic arm 5 provides support for the free movement of the screw gun 57 and can effectively counteract the reaction force generated during the screw tightening process. This reduces the labor intensity of the screw gun 57 tightening operation, making it easier and more stable for workers to operate the screw gun 57, ensuring the assembly quality of BDU product 14, and thus meeting the requirements for efficient and accurate assembly production of BDU product 14.
[0028] In this embodiment, the frame 1 includes a main base 12 and a mounting bracket 13. The mounting bracket 13 is located on the Z-axis side of the main base 12, and the working surface 10 is located on the side of the main base 12 closest to the mounting bracket 13. The laser guiding mechanism 2 and the visual inspection element 4 are both located on the mounting bracket 13. Specifically, the main base 12 is equivalent to the base of the entire machine, and the mounting bracket 13 is located on the upper part of the main base 12, providing an installation position for the laser guiding mechanism 2 and the visual inspection element 4 that overlooks the working surface 10, facilitating the projection of marking points or the acquisition of image information from top to bottom.
[0029] Specifically, the laser guiding mechanism 2 includes a first rotary driver 21, an adapter 22, a second rotary driver 23, and a laser 24, such as Figure 3 As shown, the first rotary driver 21 is located on the side of the fixed frame 13 away from the working surface 10, and the rotation axis of the first rotary driver 21 is arranged parallel to the third direction Z. The adapter 22 is located at the end of the first rotary driver 21 away from the fixed frame 13. The second rotary driver 23 is located on the adapter 22, and the rotation axis of the second rotary driver 23 is arranged perpendicular to the third direction Z. The laser 24 is located at the end of the second rotary driver 23.
[0030] Regarding the working process of the laser guiding mechanism 2: The first rotary driver 21 is connected to the side of the fixed frame 13 away from the working surface 10 via a fixed plate. The first rotary driver 21 remains stationary relative to the fixed frame 13. The adapter 22 is located at the end of the first rotary driver 21 and can rotate around the rotation axis of the first rotary driver 21. That is, the adapter 22 is fixedly connected to the rotation axis of the first rotary driver 21, meaning the first rotary driver 21 can drive the adapter 22 to rotate in the horizontal plane. The second rotary driver 23 is located on the adapter 22, so that the second rotary driver 23 and the adapter 22 move simultaneously as a whole structure. The laser 24 is located at the end of the second rotary driver 23. That is, the laser 24 is fixedly connected to the rotation axis of the second rotary driver 23, meaning the second rotary driver 23 is used to drive the laser 24 to rotate in the vertical plane.
[0031] The worktable also has a first direction X and a second direction Y, with the first direction X, the second direction Y, and the third direction Z being mutually perpendicular. This mutual perpendicularity can be strictly defined, meaning the angle between the first direction X and the second direction Y is 90°, the angle between the first direction X and the third direction Z is 90°, and the angle between the second direction Y and the third direction Z is 90°. Alternatively, it can be "approximately perpendicular," specifically, for example, where the angle between the first direction X and the second direction Y includes a certain margin of error. Considering measurement errors and limitations of the measurement system, this error is within an acceptable deviation range for a specific value as determined by a person skilled in the art. For example, the angle between the first direction X and the second direction Y is 90° ± 5°.
[0032] like Figure 3 As shown, when the position of the laser marking point along the first direction X needs to be adjusted, the second rotary driver 23 is activated while the first rotary driver 21 is deactivated. This drives the laser 24 to rotate around the rotation axis of the second rotary driver 23, thus adjusting the position. Similarly, when the position of the laser marking point along the second direction Y needs to be adjusted, the first rotary driver 21 is activated while the second rotary driver 23 assists. The first rotary driver 21 drives the laser 24 to rotate around its rotation axis, and the second rotary driver 23 corrects the position, thereby adjusting the laser marking point to the correct position. By combining the actions of the two rotary drivers, the laser 24 can project marking points onto any position on the working surface 10, ensuring the flexibility and accuracy of screw installation point marking.
[0033] Furthermore, a bracket 41 is provided on the side of the fixture 13 away from the working surface 10 along the third direction Z. The vision inspection element 4 is located on the bracket 41 and is arranged opposite to the assembly fixture 11 along the third direction Z. Specifically, the vision inspection element 4 is a high-definition camera, which is located directly above the working surface 10 to ensure that the assembly image of the BDU product 14 can be captured comprehensively and without visual obstruction.
[0034] In this embodiment, the anti-torsion robotic arm 5 includes a lifting guide rod 51, a floating seat 52, a first arm 53, and a second arm 54, as follows: Figure 4 As shown, the lifting guide rod 51 extends along the third direction Z and is connected to the frame 1. The floating seat 52 is movably installed on the lifting guide rod 51. The first arm 53 is connected to the floating seat 52. The second arm 54 is rotatably connected to the end of the first arm 53 away from the floating seat 52. The rotation axis of the second arm 54 is parallel to the third direction Z. The screw gun mounting seat 50 is located at the end of the second arm 54 away from the first arm 53.
[0035] It should be noted that a guide hole is provided in the middle of the floating seat 52. The guide hole of the floating seat 52 is slidably engaged with the lifting guide rod 51, which can ensure that the floating seat 52 can move up and down accurately along the lifting guide rod 51. The height of the first arm 53, the second arm 54, the screw gun mounting seat 50 and the screw gun 57 can be adjusted according to actual operation requirements, and the screw-tightening position can be flexibly switched.
[0036] Specifically, the anti-torsion robotic arm 5 also includes an elastic reset member 55 and a screwdriver 57. The elastic reset member 55 is located at the end of the lifting guide rod 51 away from the working surface 10, and is connected to the floating seat 52. Preferably, the elastic reset member 55 is an elastic balancer, which generates a pulling force along the third direction Z on the floating seat 52. This pulling force is used to counteract the weight of the screwdriver 57. In the absence of other external forces, the screwdriver 57 can be autonomously suspended at any position by the anti-torsion robotic arm 5, and its spatial position can be moved with only a small external force. Achieving a suspended working state through gravity balance reduces the labor intensity of workers holding the screwdriver 57 and avoids the heavy manual operation caused by the weight of the screwdriver 57.
[0037] In addition, the anti-torsion robotic arm 5 also includes an auxiliary rod 56, which is arranged parallel to and spaced apart from the lifting guide rod 51. The floating seat 52 is slidably engaged with the auxiliary rod 56. The floating seat 52, lifting guide rod 51, and auxiliary rod 56 form a double-rod sliding engagement, ensuring the sliding accuracy of the floating seat 52 along the lifting guide rod 51, thereby ensuring the anti-torsion robotic arm 5 effectively resists torsion. The key to the anti-torsion robotic arm 5 lies in its hinge joint mechanism. This mechanism allows for flexible adjustment of the horizontal position of the screwdriver 57 and incorporates an angle sensor to perceive the swing angles of the first arm 53 and the second arm 54 in real time. This enables accurate calculation and recording of the screwdriver 57's position, ensuring the accuracy of the screw installation.
[0038] Regarding the working process of the anti-torsion robotic arm 5: Along the lifting guide rod 51, the first arm 53 and the floating seat 52 can be synchronously adjusted in height, and the first arm 53 and the floating seat 52 can rotate around the axis of the lifting guide rod 51. The second arm 54 is rotatably connected to the end of the first arm 53 away from the floating seat 52. The rotation axis of the second arm 54 is parallel to the third direction Z. The angle between the second arm 54 and the first arm 53 can be flexibly adjusted with respect to the hinge joint mechanism. By changing the angle between the first arm 53 and the second arm 54, the screw gun 57 can be moved to any position in the horizontal plane.
[0039] When the screwdriver 57 is aligned with the screw hole of the BDU product 14 and begins to tighten the screw, since the position of the screwdriver 57 in the horizontal plane remains unchanged, the line connecting the two points of the screwdriver 57 and the screw hole of the BDU product 14, along with the first arm 53 and the second arm 54, forms a stable triangular structure. The torque generated when the screwdriver 57 tightens the screw is transmitted to the first arm 53 and the second arm 54, and the angle between the first arm 53 and the second arm 54 is limited by the stable triangular structure (because the horizontal position of the screw hole and the lifting guide rod 51 is fixed). The screw-tightening torque is completely counteracted by the mechanical structure of the anti-torsion robotic arm 5.
[0040] The rack 1 is also equipped with a camera monitor 6. The camera monitor 6 is positioned facing the assembly fixture 11 and is used to capture and record video and images of the assembly of BDU product 14. The camera monitor 6 is different from the visual inspection element 4. Its function is to record and monitor the assembly process, so as to facilitate subsequent traceability and analysis of assembly quality, and at the same time supervise whether the workers' operation process is standardized.
[0041] like Figure 5As shown, the BDU assembly workbench also includes a screw storage structure 3, which is located on the working surface 10. The screw storage structure 3 and the assembly fixture 11 are arranged at intervals along the second direction Y. The screw storage structure 3 includes at least two storage bins 31 and at least two indicator lights 32. The at least two storage bins 31 are arranged along the first direction X. The storage bins 31 are provided with a material retrieval port 33 on the side away from the working surface 10 and the side close to the assembly fixture 11. The at least two indicator lights 32 are arranged along the first direction X and correspond one-to-one with the storage bins 31.
[0042] The screw storage structure 3 and the assembly fixture 11 are arranged at intervals along the second direction Y, and the retrieval port 33 of the storage bin 31 is close to the assembly fixture 11, making it easy for workers to reach and pick up screws, reducing structural interference and ensuring convenient retrieval operations. Furthermore, the indicator light 32 of the screw storage structure 3 can emit lights of different colors or flashing patterns to indicate to workers which screws of the appropriate specifications should be retrieved, avoiding errors, shortening the time spent searching for and picking up screws, and improving work efficiency.
[0043] For example, when a specific size of screw is requested, the indicator light 32 corresponding to that storage bin 31 emits a green light, while the indicator lights 32 corresponding to the other storage bins 31 remain off, white, yellow, or red. The green light, compared to no light or other colors, creates a significant visual difference and more effectively attracts the worker's attention. In some embodiments, the indicator light 32 can also individually use flashing, constant light, or normally off modes. For example, when a specific size of screw is requested, the indicator light 32 corresponding to that storage bin 31 flashes, while the indicator lights 32 corresponding to the other storage bins 31 remain off or constantly on. Flashing light, compared to no light or constant light, also creates a significant visual difference and more accurately instructs the worker to retrieve the screw. Furthermore, flashing, constant light, or normally off modes can be combined with different colors.
[0044] Furthermore, the BDU assembly workbench also includes a material tray 7, which is located on the frame 1. From the assembly fixture 11 to the screw storage structure 3, the material tray 7 is gradually tilted away from the working surface 10. The material tray 7 can be used to store more screws or other parts to ensure that the assembly requirements of batch BDU products 14 can be met. When the screws on the side of the material tray 7 closest to the assembly fixture 11 are removed, the inclined surface of the material tray 7 allows the material to slide towards the assembly fixture 11, so that the material always gathers on the side closest to the assembly fixture 11, improving the convenience of material handling.
[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
