Description

Technical Field

[0001] This invention relates to the field of automotive lithium battery assembly technology, and in particular to an electrode welding and packaging device for automotive lithium battery processing. Background Technology

[0002] In the packaging and manufacturing of power batteries, lithium battery electrodes are usually fixed using laser welding technology. First, multiple independent battery modules are spliced ​​together, and then the electrode contacts of each module are connected in series by welding to assemble a complete battery pack. After the electrode welding is completed, the battery pack will enter the next process for overall packaging and protection.

[0003] For large battery packs assembled from multiple battery modules, the electrode plates need to be positioned and placed manually or by a robotic arm in advance. Manual placement is inefficient and prone to errors, while using a robotic arm will significantly increase production costs. In addition, the laser welding process itself generates fumes, which not only interfere with the recognition accuracy of the visual sensors of the welding equipment, but may also block the laser beam, increase energy loss, and affect the welding quality and stability. Summary of the Invention

[0004] This invention provides an electrode welding and packaging equipment for automotive lithium battery processing, which solves the problem that when assembling large battery packs composed of multiple battery modules, the electrodes need to be pre-positioned and placed manually or by a robotic arm. Manual placement is inefficient and prone to errors, while using a robotic arm will significantly increase production costs. In addition, the laser welding process itself generates fumes, which not only interfere with the recognition accuracy of the visual sensors of the welding equipment, but may also block the laser beam, increase energy loss, and affect the welding quality and stability.

[0005] This invention provides an electrode welding and packaging equipment for automotive lithium battery processing, specifically comprising: a welding table base, a servo motor centrally located above the welding table base, a welding rotary table fixedly connected to the upper end of the servo motor shaft, a servo motion platform mounted on the rear edge above the welding table base, a welding frame mounted in front of the servo motion platform via a bracket, a vertical connecting plate welded to the front bottom edge of the welding frame, a lifting pusher slidably connected to the rear surface of the vertical connecting plate via a guide rod slider, an electrode pushing cylinder mounted at the bottom of the welding frame, a lifting pusher fixedly connected to the lower end of the electrode pushing cylinder push rod, an electrode pressing rod mounted inside the lifting pusher, an auxiliary suction cup connected to the bottom of the electrode pressing rod, a fan connected to the right side of the welding frame, the auxiliary suction cup connected to the fan via a hose, an electrode pressing frame fixedly connected to the outside of the auxiliary suction cup, and an electrode storage compartment fixedly connected to the rear of the welding frame.

[0006] Furthermore, the front and rear halves of the welding rotary table are each provided with a welding station. The welding station has four rotary table slides. Adjusting clamps are slidably connected to the rotary table slides. A linkage rack is fixedly connected to the bottom of the adjusting clamp. A linkage gear is rotatably connected below the welding station. The four linkage racks below the same station are all meshed with the linkage gear.

[0007] Furthermore, an electromagnet is fixedly connected above the welding table base. The electromagnet is located behind the servo motor. A clamping plate is fixedly connected to a clamping plate reset spring at a location away from the servo motor. The outer end of the clamping plate reset spring is fixedly connected to the outer edge of the welding rotary table.

[0008] Furthermore, the bottom of the lifting pusher is provided with a connecting guide hole, the connecting guide hole is slidably connected to the electrode pressure rod, the electrode pressure rod is perpendicular to the lower surface of the electrode pressure frame, and the top of the electrode pressure rod is fixedly connected to a pressure rod connecting plate.

[0009] Furthermore, the electrode pressure rod is fitted with an anti-loosening tension spring, the top of which is fixedly connected to the pressure rod connecting plate, and the lower end of which is fixedly connected to the bottom of the lifting push frame.

[0010] Furthermore, the auxiliary suction cup has two smoke vents on the left and right sides of its lower sidewall.

[0011] Furthermore, the lower surface of the electrode holder is flush with the bottom surface of the auxiliary suction cup.

[0012] Furthermore, an electrode outlet is provided at the front bottom of the electrode storage compartment, and a push plate guide is provided at the rear bottom of the electrode storage compartment, with an electrode push plate slidably connected inside the push plate guide.

[0013] Furthermore, the center of the electrode pusher plate is provided with a pusher plate tooth groove, and a rack is provided on the right edge of the pusher plate tooth groove. A propulsion motor is fixedly connected to the rear of the electrode storage compartment. The shaft of the propulsion motor is connected to a propulsion gear, and the propulsion gear meshes with the rack inside the pusher plate tooth groove.

[0014] Furthermore, observation ports are provided on both sides of the electrode storage compartment.

[0015] This invention provides an electrode welding and packaging device for automotive lithium battery processing, which has the following advantages: This invention features a servo motor-driven welding rotary table with two alternating welding stations, enabling simultaneous loading and welding processes, reducing waiting time between processes. It also includes an electrode storage bin and an automatic pushing mechanism. A pusher motor, through precisely meshing pusher gears and pusher plate grooves, drives the electrode pusher plate to smoothly push the electrode sheets out of the electrode outlet. The electrode storage bin can hold multiple electrode sheets, allowing for long-term equipment operation with a single loading. This replaces the traditional manual or robotic pre-placement steps, resulting in a simpler structure, lower cost, and precise, continuous, and automatic electrode supply.

[0016] Furthermore, through the cooperation of the fan and auxiliary suction cup, as the electrode is pushed out by the electrode pusher plate, the airflow simultaneously attracts the electrode, causing it to adhere to the bottom of the auxiliary suction cup and the electrode holder, preventing the electrode from slipping. The electrode pusher cylinder then pushes down the electrode holder and electrode rod, ensuring the electrode is precisely fitted into the installation position. Anti-loosening springs maintain the electrode's tightness. During welding, the smoke generated is drawn into the exhaust port and into the fan, then discharged through the fan's exhaust vent. This near-source collection method prevents smoke from obstructing the laser path and causing energy attenuation, and completely avoids dust contamination of the vision sensor lens, thus ensuring welding positioning accuracy and energy input stability.

[0017] In addition, a clamping and straightening mechanism is designed to work in conjunction with the rotating welding turntable. As the welding turntable rotates, the welding station containing the battery pack moves closer to the laser welder. At the same time, an electromagnet is activated, which generates a magnetic attraction force on one of the adjustment clamps, causing the adjustment clamp to move towards the center of the welding station. Under the action of the linkage gear and the linkage rack and pinion of the four directions, the four adjustment clamps are driven to move synchronously towards the center of the welding station, straightening and clamping the battery pack from four directions. This enables rapid straightening and fixing, providing a foundation for high-precision welding. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1 to 13 : This invention proposes an electrode welding and packaging equipment for automotive lithium battery processing, comprising: a welding table base 1, a servo motor 2 centrally located above the welding table base 1, a welding rotary table 3 fixedly connected to the upper end of the servo motor 2's shaft, a servo motion platform 4 mounted on the rear edge above the welding table base 1, a welding frame 5 mounted in front of the servo motion platform 4 via a bracket, a vertical connecting plate 501 welded to the bottom front edge of the welding frame 5, a lifting pusher 502 slidably connected to the rear surface of the vertical connecting plate 501 via a guide rod slider, an electrode pushing cylinder 503 mounted at the bottom of the welding frame 5, a lifting pusher 502 fixedly connected to the lower end of the push rod of the electrode pushing cylinder 503, an electrode pressing rod 6 installed inside the lifting pusher 502, an auxiliary suction cup 604 connected to the bottom of the electrode pressing rod 6, a fan 8 connected to the right side of the welding frame 5, the auxiliary suction cup 604 connected to the fan 8 via a hose, and a fixed connection to the outside of the auxiliary suction cup 604. An electrode storage chamber 10 is fixedly connected to the rear of the electrode holder 7 and welding frame 5. Through the cooperation of the fan 8 and auxiliary suction cup 604, as the electrode is pushed out by the electrode push plate 1006, the airflow simultaneously attracts the electrode, causing it to adhere to the bottom of the auxiliary suction cup 604 and the electrode holder 7, preventing it from slipping. The electrode push cylinder 503 pushes down the electrode pressing rod 6 and the electrode holder 7, ensuring the electrode is precisely fitted into its installation position. The anti-loosening tension spring 602 maintains the pressure on the electrode. During welding, the smoke generated by welding is drawn into the fan 8 through the smoke exhaust port 605 and discharged through the fan 8's exhaust port. This near-source collection method prevents smoke from obstructing the laser path and causing energy attenuation, and also avoids dust contamination of the vision sensor lens, thus preventing issues with detection accuracy.

[0024] In this embodiment, the welding rotary table 3 has a welding station in its front half and a welding station in its rear half. Each welding station has four rotary table slide grooves 301. Adjusting clamps 302 are slidably connected to the rotary table slide grooves 301. A linkage rack 303 is fixedly connected to the bottom of the adjusting clamp 302. A linkage gear 304 is rotatably connected below the welding station. All four linkage racks 303 below the same station are meshed with the linkage gear 304. An electromagnet 101 is fixedly connected above the welding table base 1. The electromagnet 101 is located behind the servo motor 2. A clamp reset spring 305 is fixedly connected to one of the adjusting clamps 302 furthest from the servo motor 2. The outer end of the clamp reset spring 305 is fixedly connected to the outer edge of the welding rotary table 3. The design incorporates a clamping and straightening mechanism in conjunction with the rotating welding turntable 3. As the welding turntable 3 rotates, the welding station containing the battery pack moves closer to the laser welder 9. Simultaneously, the electromagnet 101 is activated, generating a magnetic attraction force on one of the adjusting clamps 302, causing it to move towards the center of the welding station. Under the action of the linkage gear 304 and the four linkage racks 303, the four adjusting clamps 302 are driven to move synchronously towards the center of the welding station, straightening and clamping the battery pack from four directions. This achieves rapid straightening and fixing, further improving welding efficiency and accuracy, and reducing deviations during placement.

[0025] In this embodiment, the bottom of the lifting pusher 502 is provided with a connecting guide hole 504, which is slidably connected to the electrode pressing rod 6. The electrode pressing rod 6 is perpendicular to the lower surface of the electrode pressing frame 7. The top of the electrode pressing rod 6 is fixedly connected to a pressing rod connecting plate 601. An anti-loosening tension spring 602 is sleeved on the electrode pressing rod 6. The top of the anti-loosening tension spring 602 is fixedly connected to the pressing rod connecting plate 601, and the lower end of the anti-loosening tension spring 602 is fixedly connected to the bottom of the lifting pusher 502. Under normal conditions, before the substrate enters below the electrode pressing frame 7, the lower surface of the electrode pressing frame 7 is flush with the upper surface of the electrode located at the electrode outlet 1002. As the electrode is pushed, the electrode moves to the auxiliary... Below the auxiliary suction cup 604, the negative pressure generated by the cooperation of the auxiliary suction cup 604 and the fan 8 adsorbs the electrode. As the servo motion platform 4 operates, it controls the electrode to move above the required welding position. The control electrode push cylinder 503 pushes the lifting push frame 502 downward. With the support of the anti-loosening tension spring 602, the electrode pressure rod 6 moves downward. When the electrode contacts the welding surface, the electrode push cylinder 503 continues to push the lifting push frame 502 downward, stretching the anti-loosening tension spring 602. Through the tension of the anti-loosening tension spring 602 on the pressure rod connecting plate 601, the auxiliary suction cup 604 and the electrode pressure frame 7 continuously apply downward pushing force to the electrode, keeping the electrode fixed during the welding process.

[0026] In this embodiment, the lower surface of the electrode holder 7 is flush with the bottom surface of the auxiliary suction cup 604. Two exhaust holes 605 are provided on the left and right sides of the lower edge of the side wall of the auxiliary suction cup 604. During the welding process, the exhaust holes 605 allow the welding fumes to be drawn in and enter the fan 8, and then discharged through the exhaust port of the fan 8. This near-source collection method prevents the fumes from obstructing the laser path and causing energy attenuation, and also completely avoids the adhesion and contamination of the visual sensor lens by the fumes, thereby ensuring the welding positioning accuracy and the stability of the energy input.

[0027] In this embodiment, an electrode outlet 1002 is provided at the bottom front of the electrode storage chamber 10, and a push plate guide 1003 is provided at the bottom rear of the electrode storage chamber 10. An electrode push plate 1006 is slidably connected inside the push plate guide 1003. A push plate tooth groove 1007 is provided at the center of the electrode push plate 1006, and a rack is provided on the right edge of the push plate tooth groove 1007. A push motor 1004 is fixedly connected to the rear of the electrode storage chamber 10. The shaft of the push motor 1004 is connected to a push gear 1005, and the push gear 1005 meshes with the rack inside the push plate tooth groove 1007. When supplying electrodes, the push motor 1004 is controlled to rotate, and the push gear 1005 is driven to rotate by the push motor 1004. The rotation, through the meshing connection between the propulsion gear 1005 and the internal teeth of the push plate groove 1007, forms a gear and rack transmission, which pushes the electrode push plate 1006 forward, driving the electrode push plate 1006 to smoothly push the electrode out from the electrode outlet 1002. The electrode storage chamber 10 can store multiple electrode sheets, and a single feeding can support the long-term operation of the equipment, replacing the traditional manual or robotic pre-placement steps. The structure is simpler and the cost is lower, realizing precise and continuous automatic supply of electrode sheets. At the same time as the electrode sheet is pushed out by the electrode push plate 1006, with the cooperation of the fan 8 and the auxiliary suction cup 604, the airflow adsorbs the electrode sheet, making the electrode sheet adhere to the bottom of the auxiliary suction cup 604 and the electrode pressing frame 7, preventing the electrode sheet from slipping.

[0028] In Example 2, based on Example 1, observation ports 1001 are provided on both sides of the electrode storage chamber 10 for observing the number of electrodes inside the electrode storage chamber 10. The equipment is paused in a timely manner and electrodes are added to the electrode storage chamber 10. After the bottom electrode is pushed out, the electrode push plate 1006 is reset. The electrodes inside the electrode storage chamber 10 automatically move downward under their own gravity and are added to the bottom surface inside the electrode storage chamber 10, so as to achieve continuous and stable uninterrupted feeding.

[0029] The working principle of this embodiment is as follows: After the equipment is started, the battery module is assembled and placed in the welding station above and in front of the welding rotary table 3. The welding rotary table 3 is driven by the servo motor 2 to rotate intermittently by 180 degrees, so that the station is rotated to below the laser welder 9. The electromagnet 101 is energized, and the electromagnet 101 generates a magnetic attraction force on one of the adjustment clamps 302, causing the adjustment clamp 302 to move towards the center of the welding station. Under the action of the linkage gear 304 and the linkage racks 303 of the four locations, the four adjustment clamps 302 are driven to move synchronously towards the center of the welding station, thus moving the battery module from four directions. The electrode assembly is aligned and clamped. The propulsion motor 1004, located behind the electrode storage chamber 10, drives the propulsion gear 1005 to rotate. Through meshing with the rack in the pusher tooth groove 1007 on the electrode pusher plate 1006, the electrode pusher plate 1006 is smoothly pushed forward, pushing the bottom layer of electrodes stacked at the bottom of the chamber out from the electrode outlet 1002. The blower 8, connected via a hose to the auxiliary suction cup 604, generates a stable negative pressure airflow below it. This airflow quickly and firmly adheres the pushed-out electrodes to the auxiliary suction cup 604 and the bottom surface of the surrounding electrode holder 7, ensuring that the electrodes do not slip or shift during transport. Subsequently... The servo motion platform 4 drives the welding frame 5 at its front end and the entire pickup mechanism below it to move precisely, moving the adsorbed electrode sheet above the predetermined welding position. When the electrode sheet is transported directly above the target welding position, the electrode sheet push cylinder 503 is activated, pushing the lifting push frame 502 downward along the guide rod of the vertical connecting plate 501. The electrode sheet pressing rod 6 then drives the auxiliary suction cup 604 and the electrode sheet pressing frame 7 to press down as a whole. At this time, the electrode sheet push cylinder 503 continues to apply downward pressure. Through the tensile deformation of the anti-loosening spring 602, the electrode sheet pressing frame 7 continues to press the electrode sheet tightly onto the battery module. The laser welder 9 starts working, welding the electrode sheet and the battery module. The electrode contacts are welded. At the moment when the laser generates high temperature welding, the exhaust port 605 opened on the lower edge of the side wall of the auxiliary suction cup 604 is close to the laser action point. The fan 8 is started to draw air. Through the hose and the internal cavity of the auxiliary suction cup 604, a strong directional negative pressure airflow is formed near the weld pool. The welding smoke is quickly drawn in from the exhaust port 605 before it rises and spreads, and is discharged to the outside of the equipment through the exhaust port of the fan 8. This avoids the smoke from spreading in the laser beam path, prevents the laser energy from being attenuated due to smoke and dust, and also avoids the problem of smoke and dust adhering to the lens of the equipment's vision sensor, which would reduce the recognition accuracy.Once a welding point is completed, the servo motion platform 4 can move the laser welding head to the next welding point, repeating the welding and synchronous fume extraction process. After all welding tasks on the battery module are completed, the electromagnet 101 is de-energized, and the attracted adjustment clamps 302 return to their original position under the tension of the clamp reset spring 305. The transmission of the linkage gear 304 and the linkage rack 303 causes all adjustment clamps 302 to release synchronously, releasing the clamping of the battery module. Subsequently, the servo motor 2 drives the welding rotary table 3 to rotate 180 degrees, moving the welded battery module out of the welding area. At the same time, another workstation with a battery module loaded for welding is moved into the welding position, starting the next work cycle. The operator can monitor the remaining electrode material through the observation ports 1001 on both sides of the electrode storage bin 10. When replenishment is needed, the equipment is paused for addition. The stacked electrode materials in the bin automatically sink and replenish under gravity, and are pushed again by the electrode pusher plate 1006, realizing continuous production.
