Description

Technical Field

[0001] This utility model relates to the field of battery welding technology, specifically to a cylindrical battery welding device. Background Technology

[0002] A Chinese utility model patent with publication number "CN222327033U" discloses a cylindrical battery welding device for welding the negative electrode tab of a cylindrical battery to the bottom shell. This cylindrical battery welding device includes a frame, a clamping mechanism, a driving mechanism, and welding pins. The cylindrical battery welding device of this utility model uses a driving mechanism that drives the actuating components and welding pins to simultaneously approach the placement position via an adapter plate. The actuating components control the rotation of the rotating seat of the clamping mechanism, causing the various clamping parts rotatably mounted on the fixed base to approach each other and clamp the bottom shell of the cylindrical battery. This method allows for the simultaneous clamping of the bottom shell of the cylindrical battery by at least three clamping parts under the same force, increasing the clamping area of ​​the bottom shell, avoiding excessive concentration of force on the bottom shell, reducing the risk of damage to the bottom shell, and ultimately improving the production yield of cylindrical batteries.

[0003] However, the above-mentioned welding device still relies on manual loading and unloading, which is a waste of manpower and is also quite troublesome to operate. Furthermore, the above-mentioned welding device cannot achieve continuous welding, resulting in low welding efficiency and poor practicality. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a cylindrical battery welding device that can realize automatic loading and unloading, facilitate continuous welding, and has higher welding efficiency.

[0005] The technical solution adopted by this utility model is as follows: This utility model provides a cylindrical battery welding device, including a workbench, an automatic feeding component, a positioning component, a welding component, and a dust collection component. The automatic feeding component and the dust collection component are both located on the workbench. The workbench is provided with a support unit, and two sets of the support units are symmetrically arranged. Each support unit includes a column and a support beam. The column is located on the workbench, and the support beam is located on the column. The welding component is located on the support beam. The automatic feeding component includes a feeding cylinder, a base, a rotary motor, and a turntable. The positioning component is located on the base. The workbench is provided with side frames, and two sets of the side frames are symmetrically arranged. A crossbeam is provided between the two sets of side frames. The feeding cylinder is located on the crossbeam. A guide groove is provided at the top of the feeding cylinder. The guide groove is used to guide the cylindrical battery into the feeding cylinder. The base is located on the workbench, and the rotary motor is located on the base. The turntable is located on the output shaft of the rotary motor. The turntable is provided with positioning holes, and several sets of the positioning holes are arranged in a circular array. The base is provided with a discharge groove.

[0006] Furthermore, the positioning assembly includes a hydraulic cylinder, a first clamping plate, and a second clamping plate. The hydraulic cylinder is mounted on the base, the first clamping plate is mounted on the output shaft of the hydraulic cylinder, and the second clamping plate is mounted on the base and cooperates with the first clamping plate.

[0007] Furthermore, the welding assembly includes a Y-axis linear motor, an X-axis linear motor, a Z-axis linear motor, and a welding head. There are two sets of Y-axis linear motors, which are respectively mounted on two sets of support beams. The two ends of the X-axis linear motor are respectively mounted on the sliding seats of the two sets of Y-axis linear motors. The Z-axis linear motor is mounted on the sliding seat of the X-axis linear motor, and the welding head is mounted on the sliding seat of the Z-axis linear motor.

[0008] Furthermore, the vacuuming assembly includes a vacuum cleaner, a vacuum hose, and a vacuum hood. The vacuum cleaner is mounted on the workbench, the vacuum hood is mounted on the side of the workbench near the turntable, and the two ends of the vacuum hose are respectively mounted on the air inlets of the vacuum hood and the vacuum cleaner.

[0009] Furthermore, the number of positioning holes is no less than three.

[0010] The beneficial effects of this utility model using the above structure are as follows: In this solution, a rotary motor drives the turntable to rotate. When the positioning hole on the turntable rotates to below the feeding cylinder, the cylindrical battery inside the feeding cylinder will automatically pass through the turntable and fall onto the base under the action of gravity. During the rotation of the turntable, the cylindrical battery will rotate together. When the cylindrical battery rotates to the welding component, the positioning component can clamp and position the cylindrical battery, thereby ensuring the stability of the cylindrical battery during the welding process. After welding is completed, the turntable continues to drive the cylindrical battery to rotate until the cylindrical battery rotates to the discharge trough. At this time, the cylindrical battery will automatically fall into the discharge trough under the action of gravity. At this time, the cylindrical battery is located below the turntable, making it easier to discharge. The above structure can realize automatic feeding and automatic discharge of cylindrical batteries. The dust generated during the welding process can be removed by the dust collection component.

Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-8As shown, this utility model discloses a cylindrical battery welding device, including a workbench 1, an automatic feeding assembly 2, a positioning assembly 3, a welding assembly 4, and a dust collection assembly 5. The automatic feeding assembly 2 and the dust collection assembly 5 are both mounted on the workbench 1. The workbench 1 is provided with a support unit, and two sets of support units are symmetrically arranged. The support unit includes a column 8 and a support beam 9. The column 8 is mounted on the workbench 1, and the support beam 9 is mounted on the column 8. The welding assembly 4 is mounted on the support beam 9. The welding assembly 4 includes a Y-axis linear motor 20, an X-axis linear motor 21, a Z-axis linear motor 22, and a welding head 23. There are two sets of Y-axis linear motors 20, and the two sets of Y-axis linear motors 20 are respectively mounted on the two sets of support beams 9. The two ends of the X-axis linear motor 21 are respectively mounted on the sliding seats of the two sets of Y-axis linear motors 20. The Z-axis linear motor 22 is mounted on the sliding seat of the X-axis linear motor 21. The welding head 23 is mounted on the sliding seat of the Z-axis linear motor 22.

[0024] The automatic feeding assembly 2 includes a feeding cylinder 10, a base 11, a rotary motor 12, and a turntable 13. The positioning assembly 3 is located on the base 11. The worktable 1 is provided with side frames 6, which are arranged symmetrically in two sets. A crossbeam 7 is provided between the two sets of side frames 6. The feeding cylinder 10 is located on the crossbeam 7. The top of the feeding cylinder 10 is provided with a guide groove 14, which is used to guide cylindrical batteries into the feeding cylinder 10. The base 11 is located on the worktable 1. The rotary motor 12 is located on the base 11. The turntable 13 is located on the output shaft of the rotary motor 12. The turntable 13 is provided with positioning holes 16, which are arranged in a circular array in several sets. The base 11 is provided with a discharge groove 15. The number of positioning holes 16 is not less than three.

[0025] The positioning assembly 3 includes a hydraulic cylinder 17, a first clamping plate 18, and a second clamping plate 19. The hydraulic cylinder 17 is mounted on the base 11, the first clamping plate 18 is mounted on the output shaft of the hydraulic cylinder 17, and the second clamping plate 19 is mounted on the base 11 and cooperates with the first clamping plate 18.

[0026] The vacuuming assembly 5 includes a vacuum cleaner 24, a vacuum hose 25, and a vacuum hood 26. The vacuum cleaner 24 is located on the workbench 1, and the vacuum hood 26 is located on the side of the workbench 1 near the turntable 13. The two ends of the vacuum hose 25 are respectively located on the air inlet of the vacuum hood 26 and the vacuum cleaner 24.

[0027] In practical use, cylindrical batteries are conveyed to the guide trough 14 via an external feeding device. The cylindrical batteries slide into the feeding cylinder 10 along the guide trough 14 and automatically move downwards under gravity. The rotary motor 12 drives the turntable 13 to rotate. During the rotation of the turntable 13, if the feeding cylinder 10 is not aligned with the positioning hole 16, the cylindrical batteries will be supported by the turntable 13. When the feeding cylinder 10 is aligned with the positioning hole 16, the cylindrical batteries will pass through the positioning hole 16 and fall onto the base 11. Once the cylindrical batteries have fallen into the positioning hole 16... The rotation of turntable 13 causes the cylindrical battery to rotate as well. When the cylindrical battery rotates to the welding assembly 4, hydraulic cylinder 17 is activated, which drives the first clamping plate 18 to move closer to the cylindrical battery. The first clamping plate 18 and the second clamping plate 19 clamp and fix the cylindrical battery, and then welding can be performed on the cylindrical battery through welding head 23. The position of welding head 23 can be flexibly adjusted by Y-axis linear motor 20, X-axis linear motor 21, and Z-axis linear motor 22 to better meet welding requirements. During the welding process, vacuum cleaner 24, vacuum hose 25, and vacuum hood 26 can remove dust. After welding is completed, the clamping and fixing of the cylindrical battery by the first clamping plate 18 and the second clamping plate 19 is removed. The cylindrical battery continues to rotate via the turntable 13. When the cylindrical battery rotates to the discharge trough 15, it will automatically fall into the discharge trough 15 under the action of gravity. At this time, the cylindrical battery is located below the turntable 13. When discharging, the cylindrical battery can be directly removed by an external robotic arm, making discharge more convenient. The above structure enables uninterrupted continuous welding, greatly improving welding efficiency.

[0028] In summary, this solution uses a rotary motor 12 to drive the turntable 13 to rotate. When the positioning hole 16 on the turntable 13 rotates to below the feeding cylinder 10, the cylindrical batteries inside the feeding cylinder 10 automatically pass through the turntable 13 and fall onto the base 11 under gravity. During the rotation of the turntable 13, the cylindrical batteries rotate together. When the cylindrical batteries rotate to the welding assembly 4, the positioning assembly 3 clamps and positions them, ensuring their stability during the welding process. After welding, the turntable 13 continues to rotate the cylindrical batteries until they reach the discharge trough 15. At this point, the cylindrical batteries automatically fall into the discharge trough 15 under gravity. Since the batteries are now below the turntable 13, they are easier to discharge. This structure enables automatic feeding and discharging of cylindrical batteries. The dust collection assembly 5 removes dust generated during the welding process.
