Description
Technical Field
[0001] This invention relates to the field of battery processing technology, specifically to a battery negative electrode cap welding device. Background Technology
[0002] A battery is an energy storage device that converts chemical energy into electrical energy. Its core consists of a positive electrode, a negative electrode, an electrolyte, a separator, and a casing. According to the material, it can be divided into lithium batteries, lead-acid batteries, nickel-metal hydride batteries, etc. It is widely used in consumer electronics, new energy vehicles, energy storage and other fields. Its performance directly depends on the electrode material, assembly process and sealing reliability. The negative electrode cap, as a core component of the battery, plays a key role in ensuring the safety and stability of the battery.
[0003] The negative electrode cap primarily serves four core functions: first, current conduction, acting as the negative electrical interface to ensure stable transmission of internal current to the external circuit; second, sealing and protection, preventing electrolyte leakage, blocking air and moisture intrusion, and avoiding battery performance degradation; third, structural support, withstanding mechanical stress and impact during charging and discharging; and fourth, safety protection, with some sections integrating explosion-proof valves that can release gas to prevent explosions under abnormal pressure. Welding the battery negative electrode cap is a core process in battery manufacturing that ensures the reliability and sealing of electrical connections, directly affecting the battery's safety and lifespan.
[0004] In existing technology, workers place the battery and negative electrode cap inside the mold, and then a welding device welds the battery and negative electrode cap inside the mold. During welding, a certain amount of harmful gases are generated, including metal fumes, volatile organic compounds, inert gases, and ozone. Workers are in the welding area for a long time to perform loading and unloading operations. Although they wear masks for protection, they will still inhale a certain amount of harmful gases.

The upper end of the workbench 1 is equipped with a bracket 14, and the upper end of the bracket 14 is equipped with a welding head 15. A mounting frame 8 is installed on the upper part of the mounting platform 4. An air intake plate 11 and an air outlet plate 13 are installed at one end of the mounting frame 8. A hazardous gas purifier 9 is installed inside the mounting platform 4. The hazardous gas purifier 9 includes an air pump, a dust collection area, and an activated carbon purification area. An air intake pipe 10 and an air outlet pipe 12 are respectively installed at the air inlet and outlet ends of the hazardous gas purifier 9. One end of the air intake pipe 10 and one end of the air outlet pipe 12 are connected to the air intake plate 11 and the air outlet plate 13, respectively. The air intake plate 11 and the air outlet plate 13 are suspended above the welding area. Welding operations generate hazardous gases. The suction plate 11 absorbs harmful gases, which enter the harmful gas purifier 9 through the suction pipe 10. The harmful gas purifier 9 first separates the dust inside the harmful gas from the harmful gas itself, and then purifies the harmful gas through activated carbon. The purified gas is discharged through the exhaust pipe 12, and then blown out through the exhaust plate 13. The blown gas forms an airflow wall on one side, preventing the harmful gas from flowing out from the side away from the suction plate 11, reducing the flow rate of the harmful gas, and improving the absorption efficiency of the suction plate 11 for the harmful gas.
[0033] Please see Figure 3 - Figure 5 The suction plate 11 and the exhaust plate 13 are symmetrically arranged, and both the suction plate 11 and the exhaust plate 13 are arc-shaped. The arc-shaped arrangement of the suction plate 11 and the exhaust plate 13, and the outer end of the welding area form a circular airflow wall, reduce the leakage of harmful gases.
[0034] Please see Figure 6 - Figure 8 A first hydraulic pump 18 is installed on the upper end of the movable seat 16. A first hydraulic column 19 is installed at the output end of the first hydraulic pump 18. A movable plate 20 is installed at one end of the first hydraulic column 19. When the first hydraulic pump 18 is started, it drives the first hydraulic column 19 to start, thereby driving the movable plate 20 to move.
[0035] Please see Figure 6 - Figure 8 Multiple sets of telescopic columns 21 are installed on the upper end of the movable plate 20. Each set of telescopic columns 21 has a first spring 22 on its outer wall. Each set of telescopic columns 21 has a retractable cylinder 24 movably installed on its upper end. Each set of retractable cylinders 24 has a movable plate 23 installed on its outer wall. A placement platform 25 is mounted on the upper end of the movable seat 16. A placement groove 26 is opened on the upper end of the placement platform 25. One end of each set of retractable cylinders 24 extends into the placement groove 26. When the movable plate 20 moves, it pushes the multiple sets of telescopic columns 21 to move upward, thereby driving the movable plate 23 and the multiple sets of retractable cylinders 24 to move.
[0036] Please see Figure 6 - Figure 11The bottom end of the placement mold 35 is movably connected to the placement groove 26. The bottom end of the placement mold 35 has multiple sets of reserved holes 38, and the multiple sets of reserved holes 38 correspond to multiple sets of shrink cylinders 24. Limiting plates 39 are movably installed inside the multiple sets of reserved holes 38. Connecting rods 41 are symmetrically installed on the outer walls of the multiple sets of limiting plates 39. Toothed plates 42 are installed on the upper ends of the multiple sets of connecting rods 41. Second springs 40 are installed on the upper ends of the multiple sets of limiting plates 39, and one end of the multiple sets of second springs 40 is movably connected to the inner wall of the multiple sets of reserved holes 38. The multiple sets of shrink cylinders 24 are displaced and enter the multiple sets of reserved holes 38 to improve the stability of the placement mold 35. The multiple sets of shrink cylinders 24 push the multiple sets of limiting plates 39 upward, thereby driving the multiple sets of connecting rods 41 to move, and then driving the multiple sets of toothed plates 42 to move upward.
[0037] Please see Figure 9 The upper end of the placement mold 35 has multiple battery compartments 36 and multiple cap slots 37, and the multiple cap slots 37 correspond to the multiple battery compartments 36 respectively. Multiple batteries and multiple negative electrode caps are placed inside the battery compartments 36 and the cap compartments 37.
[0038] Please see Figure 9 - Figure 11 Multiple sets of movable discs 43 are movably installed on the outer wall of the mold 35. Each set of movable discs 43 has a movable shaft 44 installed at one end, and each set of movable shafts 44 has a movable gear 45 installed at one end. The movable gears 45 are respectively engaged with multiple sets of toothed plates 42. Each set of movable discs 43 has a limit rod 46 installed at the other end, and the limit rods 46 are offset from the center end of the set of movable discs 43. After the multiple sets of toothed plates 42 are displaced upward, they are respectively engaged with the multiple sets of movable gears 45. Therefore, the multiple sets of movable gears 45 rotate, thereby driving the multiple sets of movable shafts 44 to rotate. Adjacent sets of movable shafts 44 rotate in opposite directions. The multiple sets of movable shafts 33 drive the multiple sets of movable discs 43 to rotate, thereby driving the multiple sets of limit rods 46 to rotate. The multiple sets of limit rods 46 rotate around the multiple sets of movable discs 43.
[0039] Please see Figure 7 - Figure 8A mounting plate 27 is installed on the upper end of the movable base 16. A second hydraulic pump 28 is installed on the outer wall of the mounting plate 27. A second hydraulic column 29 is installed at the output end of the second hydraulic pump 28. A movable block 31 is installed on the upper end of the second hydraulic column 29. A pressure plate 32 is installed on the upper end of the movable block 31. Multiple sets of slots 33 are opened at the lower end of the multiple sets of pressure plates 32, and the multiple sets of slots 33 correspond to multiple sets of battery compartments 36 respectively. A mounting box 30 is installed on the outer wall of the second hydraulic pump 28, and the inner wall of the mounting box 30 is movably connected to the outer wall of the movable block 31. When the second hydraulic pump 28 is started, it drives the second hydraulic column 29 to move downward, drives the movable block 31 to move downward, and thus drives the pressure plate 32 to move downward. The multiple sets of slots 33 cooperate with the multiple sets of battery compartments 36 to press and fix the multiple sets of batteries.
[0040] Please see Figure 2 - Figure 8 The upper end of the mounting platform 4 is provided with a sliding groove 5, and the bottom end of the movable seat 16 is provided with a slider 17. The outer wall of the slider 17 is movably connected to the inner wall of the sliding groove 5. The slider 17 moves within multiple sets of sliding grooves 5 to improve the stability of the movable seat 16 during movement.
[0041] Please see Figure 2 - Figure 7 The second hydraulic pump 28 has a limit block 34 installed on its outer wall. Two sets of drive shafts 7 are movably installed inside the mounting platform 4, and the two sets of drive shafts 7 are connected by a toothed synchronous belt. A drive motor 6 is mounted on one side of the mounting platform 4, and the output end of the drive motor 6 is connected to one set of drive shafts 7. The outer walls of both sets of drive shafts 7 are threaded to the inner wall of the limit block 34. When the drive motor 6 starts, it drives one set of drive shafts 7 to rotate. The two sets of drive shafts 7 are connected by a toothed synchronous belt, so the two sets of drive shafts 7 rotate synchronously. The outer walls of both sets of drive shafts 7 are threaded to the inner wall of the limit block 34, so the limit block 34 is displaced.
[0042] The working principle of this invention is as follows: When the staff uses the device to perform welding operations on the negative electrode cap of the battery, the staff takes out multiple sets of batteries and multiple sets of negative electrode caps from the battery placement box 3 and the negative electrode cap placement box 2 respectively, and then puts the multiple sets of batteries and multiple sets of negative electrode caps into the battery compartment 36 and the cap compartment 37 respectively. Then the staff puts the placement mold 35 into the placement groove 26. Multiple sets of reserved holes 38 correspond to multiple sets of shrink cylinders 24 respectively. The staff starts the second hydraulic pump 28 and the first hydraulic pump 18 in sequence. When the second hydraulic pump 28 is started, it drives the second hydraulic column 29 to move downward, which in turn drives the moving block 31 to move downward, thereby driving the pressure plate 32 to move downward. The multiple sets of slots 33 cooperate with the multiple sets of battery compartments 36 to press and fix the multiple sets of batteries. After multiple sets of batteries are pressed and fixed, the first hydraulic pump 18 is started, which drives the first hydraulic column 19 to move upward, thereby pushing multiple sets of telescopic columns 21 to move upward, and then driving the movable plate 23 and multiple sets of shrink cylinders 24 to move. The multiple sets of shrink cylinders 24 enter the interior of multiple sets of reserved holes 38 respectively, improving the stability of the mold 35. The multiple sets of shrink cylinders 24 push multiple sets of limit plates 39 to move upward, thereby driving multiple sets of connecting rods 41 to move, and then driving multiple sets of toothed plates 42 to move upward. When the multiple sets of toothed plates 42 move upward, they mesh with the multiple sets of movable gears 45, causing the multiple sets of movable gears 45 to rotate. This drives the multiple sets of movable shafts 44 to rotate, with adjacent sets of movable shafts 44 rotating in opposite directions. The multiple sets of movable shafts 33 drive the multiple sets of movable discs 43 to rotate, which in turn drives the multiple sets of limiting rods 46 to rotate. The multiple sets of limiting rods 46 rotate around the multiple sets of movable discs 43. After the multiple sets of limiting rods 46 rotate, they cooperate to press and fix the multiple sets of negative electrode caps, improving the stability of the multiple sets of negative electrode caps after placement. Furthermore, after the multiple sets of limiting rods 46 rotate, they press against the upper end of the multiple sets of negative electrode caps, reducing the friction between the multiple sets of limiting rods 46 and the multiple sets of negative electrode caps, thus reducing the damage rate of the negative electrode caps. After multiple sets of batteries and multiple sets of negative electrode caps are fixed in place, the staff starts the drive motor 6 and the harmful gas purifier 9. The drive motor 6 intermittently drives a set of drive shafts 7 to rotate. The two sets of drive shafts 7 are connected by a toothed synchronous belt and rotate synchronously. The outer walls of the two sets of drive shafts 7 are threadedly connected to the inner wall of the limit block 34, so the limit block 34 is displaced, thereby driving the second hydraulic pump 28 to move, and then driving the mounting plate 27 and the moving seat 16 to move. During the movement of the movable seat 16, the harmful gas purifier 9 is activated, causing the suction plate 11 to generate suction. After the battery and negative electrode cap move to the lower area of the suction plate 11, multiple sets of limiting rods 46 press and fix multiple sets of negative electrode caps respectively, preventing multiple sets of negative electrode caps from being moved out of the cap groove 37 due to the suction. The suction plate 11 also absorbs the dust on the upper part of the negative electrode cap, preventing the dust from affecting the subsequent welding operation and causing a false weld. After a set of battery welding ends and negative electrode caps move to the welding area, the two sets of drive shafts 7 stop rotating, the movable seat 16 stops moving, and the welding head 15 welds the battery and negative electrode cap. When the welding head 15 performs welding operations on the battery and negative electrode cap, the welding operation generates harmful gases. The suction plate 11 absorbs the harmful gases, which then enter the harmful gas purifier 9 through the suction pipe 10. The harmful gas purifier 9 first separates the dust inside the harmful gases from the harmful gases themselves, and then purifies the harmful gases through activated carbon. The purified gas is discharged through the exhaust pipe 12 and then blown out through the exhaust plate 13. The blown gas forms an airflow wall on one side, preventing the harmful gases from flowing out from the side away from the suction plate 11, reducing the flow rate of harmful gases, improving the absorption efficiency of the suction plate 11 for harmful gases, and improving the health of the workers. After one set of batteries and negative electrode caps is welded, the two sets of drive shafts 7 rotate, driving the moving seat 16 to move, so that another set of batteries and negative electrode caps moves to the welding area. The welded battery negative electrode cap passes through the lower area of the exhaust plate 13, and the airflow blows towards the welding end of the battery negative electrode cap, improving the cooling efficiency of the welding end of the battery negative electrode cap.
