Description

Technical Field

[0001] This invention relates to the field of laser welding technology, and in particular to a welding device for aluminum busbars of multi-specification adaptable battery modules. Background Technology

[0002] Laser welding technology has evolved into a processing system integrating optomechanical and electronic control, encompassing specific technical directions such as beam control technology, wire feeding coordination technology, and process sensing technology. Among them, beam control can achieve precise energy distribution by adjusting the pulse waveform, pulse width, and beam shape; wire feeding coordination compensates for the welding gap by matching the wire diameter, wire feeding speed, and laser power; and process sensing monitors signals such as plasma, light radiation, and acoustic emission during the welding process through various sensing devices. This technology is widely used in fields such as automotive electronics and new energy, and plays an important role, especially in battery module manufacturing, serving as a key technical support for high-precision and high-efficiency metal joining processing.

[0003] Chinese Patent Publication No. CN119187877B discloses a multi-specification adaptable aluminum busbar welding device for battery modules. The device includes a workbench with a mounting plate on top. A battery module body is mounted on the top of the mounting plate. A clamping and fixing mechanism is provided between the outer wall of the battery module body and the mounting plate. Two pairs of aluminum busbar bodies are mounted on the top of the battery module body, and a deformation clamping mechanism is provided on the outer wall of each aluminum busbar body. A pulling and rotating mechanism is provided between the top of the workbench and the bottom of the mounting plate. A sliding cylinder is fixedly connected to the top of the workbench via a pair of vertical plates, and a connecting plate is fixedly connected to one end of the sliding cylinder. This device, through its deformation clamping mechanism, can adapt to different specifications of aluminum busbar bodies, ensuring sufficient contact and clamping fixation during clamping, thus guaranteeing both clamping and fixing effectiveness and usability. However, the patent still has the following drawbacks: Although the aforementioned literature can adapt to the clamping and fixing of aluminum busbars of different specifications through deformation clamping mechanism in actual processing, it is not equipped with aluminum busbar surface dust removal, leveling and automatic calibration and positioning mechanism for battery module. It is easy for surface impurities and position deviations to affect welding accuracy and welding quality. At the same time, it lacks welding fume and impurity treatment device, which poses a hidden danger to the working environment. Moreover, the overall multi-specification adaptability, positioning accuracy and automation level are low, which cannot meet the needs of efficient and stable battery module aluminum busbar welding.

Figure 4 and Figure 5 As shown, the pretreatment mechanism 3 includes two calibration mechanisms 31, which are symmetrically arranged. These two calibration mechanisms 31 work together to accurately align and position battery modules of different specifications, ensuring the correct position for subsequent aluminum busbar welding. Each calibration mechanism 31 has a support platform 32 fixedly connected to its bottom. The support platform 32 supports and fixes the calibration mechanism 31 and the connecting plate 33, providing a stable mounting foundation for the components of the pretreatment mechanism 3. Each support platform 32 has a connecting plate 33 fixedly connected to its left side, used for mounting... The wiping wheel 34 is connected to the two connecting plates 33 on their adjacent sides and rotates together. During the transportation of the battery module and aluminum busbar, the wiping wheel 34 presses down on the aluminum busbar and removes surface dust, preventing dust residue from affecting the welding fit and welding quality between the aluminum busbar and the battery module. The bottom of the two support platforms 32 is provided with a cooperating mechanism 35. The cooperating mechanism 35 is used to cooperate with the operation of the transport mechanism 66 of the transfer mechanism 6, thereby driving the calibration mechanism 31 to achieve the alignment and positioning of the battery module, realizing the coordinated cooperation between pre-processing and transfer operations.

[0023] Please see further. Figure 5As shown, the calibration mechanism 31 includes a housing 311, which is the main body of the calibration mechanism 31 and is used to house internal components such as the liquid storage box 313 and connecting posts 314, providing protection and fixation. A calibration frame 312 is slidably connected to one side of the housing 311. The calibration frame 312 directly contacts the battery module and clamps and aligns the battery module through its own sliding, ensuring that the battery module is in the preset welding position. A calibration wheel is rotatably connected to the inner cavity of the calibration frame 312. The calibration wheel reduces the friction between the calibration frame 312 and the battery module, preventing scratches and damage to the surface of the battery module during alignment, and also assisting the calibration frame 312 to slide smoothly. A liquid storage box 313 is fixedly connected to the right side of the inner cavity of the housing 311. The liquid storage box 313 stores hydraulic fluid to provide hydraulic power for the sliding of the calibration frame 312. Two connecting posts 314 are slidably connected to the inner cavity of the liquid storage box 313. 314, connecting column 1 314 is used to transmit hydraulic power to drive the calibration frame 312 to slide. The front of the two connecting columns 1 314 is fixedly connected to a hydraulic plate 315. The hydraulic plate 315 slides under the push of hydraulic fluid, thereby driving the two connecting columns 1 314 to move synchronously, ensuring the smooth movement of the calibration frame 312. The bottom of the calibration frame 312 is fixedly connected to two fixing tubes 2 318. The front of each fixing tube 2 318 is slidably connected to a fixing tube 1 316.

The connecting rod 352 is used to transmit the squeezing force of the mating strip 353, push the hydraulic fluid in the hydraulic pipe 351 to flow, and thus drive the calibration mechanism 31 to move. The mating strip 353 is fixedly connected to one side of the connecting rod 352. The mating strip 353 is used to cooperate with the mating wheel 666 of the transfer mechanism 6. Through the engagement of the mating wheel 666 with the groove on the surface of the mating strip 353, the mating strip 353 is driven to realize the inward contraction and outward expansion. The outer surface of the mating strip 353 cooperates with the transfer mechanism 6 to ensure the coordinated operation of the transfer mechanism 6 and the pretreatment mechanism 3, so as to realize the synchronous operation of battery module transfer and calibration.

Several air nozzles are fixedly connected to the bottom of the air blowing pipe 42. The air nozzles can disperse the airflow in the air blowing pipe 42, increase the blowing coverage area, and ensure that dust on all parts of the aluminum strip surface can be effectively removed. The air pump 43 is fixedly connected to the other end of the air blowing pipe 42. The air pump 43 is the power source of the cooperating mechanism 2 4. On the one hand, it provides the airflow required for blowing the air blowing pipe 42, and on the other hand, it provides the smoke from the suction mechanism 44. Powered by air suction, the air pump 43 is fixedly connected to a suction mechanism 44 at its bottom. The suction mechanism 44 is used to extract and treat the fumes and impurities generated during the welding process, preventing fumes from polluting the operating environment and preventing impurities from affecting the welding quality.

The inner cavity of the first suction pipe 45 is slidably connected to a second suction pipe 46, which can be adjusted according to the position of the welding mechanism 53 to ensure that the second suction pipe 46 can be accurately aligned with the welding position and efficiently extract welding fumes. The second suction pipe 46 is fixedly connected to one side of the second processing mechanism 53, realizing the synchronous movement of the second suction pipe 46 and the welding mechanism 53 and ensuring the stability of the fume extraction effect.

The clamping head 656 directly contacts the transport platform 665 and fixes the transport mechanism 66 by clamping the transport platform 665, ensuring that the transport mechanism 66 does not move during the welding process. The rear part of the sliding plate 655 is fixedly connected to the connecting column 2 657, which is used to connect the sliding plate 655 and the rotating wheel 2 658 and transmit the guiding force of the rotating wheel 2 658. The other end of the connecting column 2 657 is rotatably connected to the rotating wheel 2 658. The rotating wheel 2 658 slides in cooperation with the mating groove 24 of the processing seat 21 to provide guidance for the movement of the clamping mechanism 65, ensuring that the clamping mechanism 65 can move accurately to the designated position and achieve precise clamping of the transport mechanism 66. Furthermore, the transport mechanism 66 includes a connecting leg 661, with a support rod 664 fixedly connected to the upper end of the connecting leg 661. The support rod 664 supports and fixes the transport platform 665, improving the load-bearing capacity of the transport platform 665 and ensuring stable support of the battery module and aluminum busbar. The transport platform 665 is directly supported by the support rod 664, ensuring that the battery module and aluminum busbar do not shift during transport. Rolling wheels 662 are rotatably connected to both the front and rear sides of the connecting leg 661. The rolling wheels 662 reduce the friction between the transport mechanism 66 and the mating groove 22 of the processing seat 21, allowing the transport mechanism 66 to move smoothly and steadily along a preset trajectory. Both the front and rear sides of the moving wheel 662 are slidably connected to the inner cavity of the mating groove 22. The mating groove 22 provides a sliding guide for the rolling wheel 662, ensuring that the transport mechanism 66 can move accurately along the preset trajectory. The left side of the connecting leg 661 is fixedly connected to the mating bracket 663, which is used to install and fix the mating wheel 666, ensuring that the mating wheel 666 can stably mate with the mating strip 353. Both the front and rear sides of the mating bracket 663 are rotatably connected to the mating wheel 666. The mating wheel 666 mates with the groove on the surface of the mating strip 353, driving the mating strip 353 to retract inward and expand outward, thereby driving the calibration mechanism 31 to align and position the battery module, realizing the coordinated action of the transport mechanism 66 and the pre-processing mechanism 3.

[0029] Please see Figure 9As shown, the clamping mechanism 65 located at the rear includes a control valve 651. The control valve 651 is used to control the clamping action of the clamping mechanism 65. When the fixed block 67 drives the transport mechanism 66 to the designated position, the sensor switch inside the control valve 651 is squeezed, thereby controlling the clamping mechanism 65 to achieve the clamping action. A connecting rod 652 is slidably connected to the right side of the control valve 651. The connecting rod 652 is used to transmit the control signal of the control valve 651, driving the fixed platform 653 and the sliding plate 655 to move. The fixed platform 653 is fixedly connected to the upper end of the connecting rod 652. The fixed platform 653 is used to install and fix the sliding plate 655 and the spring 654. The sliding plate 655 is slidably connected to the inner cavity of the fixed platform 653. The sliding plate 655 is used to drive the clamping head 656 to move, realizing the clamping and releasing of the transport mechanism 66 by the clamping head 656. The spring 654 is fixedly connected to the front of the sliding plate 655. The spring 654 uses its own... The elasticity provides the sliding plate 655 with the reset power. After the clamping action is completed, it drives the sliding plate 655 and the clamping head 656 to reset so that subsequent clamping actions can be performed. The upper part of the sliding plate 655 is fixedly connected to the clamping head 656 for clamping the transport platform 665. The clamping head 656 directly contacts the transport platform 665 and fixes the transport mechanism 66 by clamping the transport platform 665, ensuring that the transport mechanism 66 does not move during the welding process. The rear part of the sliding plate 655 is fixedly connected to the connecting column 657, which is used to connect the sliding plate 655 and the rotating wheel 658 and transmit the guiding force of the rotating wheel 658. The other end of the connecting column 657 is rotatably connected to the rotating wheel 658. The rotating wheel 658 slides in cooperation with the mating groove 24 of the processing seat 21, providing guidance for the movement of the clamping mechanism 65 and ensuring that the clamping mechanism 65 can move to the designated position to achieve the clamping of the transport mechanism 66.

[0030] Further, combining the above embodiments one, two, and three, the working principle of this solution is further explained: When the operator uses this device, firstly, an appropriate amount of aluminum strip needs to be placed above the battery module. Subsequently, motor three 61 will start, driving the three rotating wheels one 63 to rotate through the transmission rod 62 fixedly connected to the output end. During the rotation of the three rotating wheels one 63, the transmission belt two 64 fixedly connected to its outer surface will drive the three rotating wheels one 63 on the other side to rotate. Under the coordinated rotation of the three rotating wheels one 63, the transmission belt two 64 begins to run smoothly. On the transmission belt two 64 located in the middle, the two fixed blocks 67 move synchronously with the transmission belt, thereby driving the rotating wheels to rotate. The transport mechanism 66 transports the battery module and the aluminum strip on its surface along a preset track. At the same time, during the movement of the transport mechanism 66, the rolling wheels 662 rotatably connected to both sides of the internal connecting leg 661 will transport along the preset track. During the transport, the connecting plate 33 installed on the upper end of the two support platforms 32 will press and remove surface dust from the aluminum strip on the upper part of the battery module through the wiping wheel 34. Subsequently, the mating wheels 666 rotatably connected to the left and right sides of the bracket 663 will engage with the adjacent mating strip 353. By engaging with the groove on the surface of the mating strip 353, the two mating strips 353 can be synchronously retracted inward and extended outward. Furthermore, as the two mating strips 353 unfold outward, the connecting rod 352, which is fixedly connected to the side of the two mating strips 353 that is far apart from each other, will squeeze the liquid in the inner cavity of the hydraulic pipe 351, so that the liquid in the inner cavity of the hydraulic pipe 351 enters the reservoir box 313 and squeezes the hydraulic plate 315, driving the two connecting columns 314 to push the fixedly connected calibration frame 312 to align the battery module for subsequent welding processing. Furthermore, during the inward retraction of the two mating strips 353, the two springs 317 installed at the bottom of the calibration frame 312 will pull the calibration frame 312 back through their own elasticity. Subsequently, during the retraction of the calibration frame 312, the liquid in the inner cavity of the liquid storage box 313 will be squeezed by the connecting column 314, so that the liquid in the inner cavity of the liquid storage box 313 will reset the connecting rod 352 through the hydraulic pipe 351, so as to align and position the battery module for subsequent expansion or contraction. After the pre-processing mechanism 3 calibrates the battery module and the aluminum busbar on the upper part of the battery module, the middle transport mechanism 66 will continue to transport to the right under the drive of the fixed block 67. Then, the air pump 43 will blow air onto the surface of the aluminum busbar through the air blowing pipe 42 to avoid dust residue affecting the welding efficiency. After the fixed block 67 transports the transport mechanism 66 to the appropriate position, the sensing and control switches inside the two control valves 651 will slide and squeeze the bottom of the connecting rod 652, and then clamp the two transmission belts 64 on the front and rear sides to move. During the movement, the rotating wheel 658 connected to the rear of the two sliding plates 655 through the connecting column 657 will cooperate with the mating groove 24. Then, through the guide of the mating groove 24, the clamping head 656 will be driven to clamp the transport mechanism 66. Then, the transport mechanism 66, together with the battery module and the aluminum busbar on the upper surface, will be placed on the upper part of the processing table 26. At this time, the motor 515 fixedly connected to one side of the processing base 21 will start and drive the two transmission belts 514 to rotate. Then, the two moving blocks 513 connected to the outer surface of the moving blocks 513 will drive the moving shell 521 to move left and right. The motor 525 fixedly connected to one side of the moving shell 521 will drive the threaded rod 523 to rotate to position the aluminum busbar on the surface of the battery module. Then, the aluminum busbar and the battery module are welded by the welding head 534. During the welding process, since the suction mechanism 44 has been started, the suction pipe 46 will extract the fumes and impurities generated during welding. The extracted fumes and impurities will enter the suction mechanism 44 through the suction pipe 45 for processing, and then be blown out through the blowing pipe 42 fixed at the output end of the air pump 43. After the welding operation is completed, the second motor 525 will rotate in the opposite direction, driving the second threaded rod 523 to rotate, which in turn causes the sliding block 524 to move back along the sliding column 522. The welding mechanism 53 then returns to its initial position, preparing for the next welding operation. At the same time, the first motor 515 in the first transmission mechanism 51 will also rotate forward or reverse according to actual needs, driving the moving block 513 to reciprocate on the threaded rod 512 through the first transmission belt 514, thereby adjusting the overall position of the second transmission mechanism 52 and the welding mechanism 53 to adapt to the welding requirements of different specifications of battery modules. Once a batch of battery modules is welded, the transfer mechanism 6 will be restarted. Through the coordinated action of motor 61, transmission rod 62, rotating wheel 63, and transmission belt 64, the transport mechanism 66 and the battery modules on it will be moved off the processing table 26 and transported along the preset track to the next process for return.
