Technical Field

[0002] Lithium-ion batteries are usually composed of multiple cells to form a battery pack to meet the voltage and capacity requirements of different devices. Nickel strips have good conductivity. By welding them between the individual cells, they can provide a low-resistance path for the current, ensuring smooth current transmission within the battery pack, so that the battery pack can work normally and provide stable power for the device.

[0003] In the battery loading process, lithium-ion batteries are usually placed manually in the welding area and the two batteries are aligned and merged.

This seriously affects the efficiency of lithium-ion battery welding;

When encountering thicker nickel strips, if the welding pressure cannot be properly adjusted, the nickel strips are prone to incomplete melting and weak welding; and for nickel strips of conventional thickness, if the welding parameters remain unchanged, the electrode connection points of lithium-ion batteries may be damaged due to excessive pressure and high temperature.

[0037] See also Figures 4 to 8 The welding device 4 includes a lifter 41, which is fixedly connected to the upper surface of the welding table 1 and symmetrically on both sides of the lithium-ion battery. A storage bin 42 is fixedly connected to the side close to the top of the lifter 41. Nickel strips 43 are stacked and installed in the inner cavity of the storage bin 42.

[0039] The second toothed clamping plates 4416 are all fixedly connected to the outer wall of the storage bin 42, the first toothed clamping plates 447 are all slidably connected to the side wall of the Z-shaped plate 443, the top of the first toothed clamping plates 447 are all fixedly connected to the columns 448, the top of the columns 448 are all fixedly connected to the slide plates 449, the storage bin 42 is symmetrically fixedly connected with guide plates 4410 on both sides of the first slide groove 441, the side of the guide plates 4410 close to each other is symmetrically provided with vertical grooves 4411, the side of the guide plates 4410 close to each other and away from the storage bin 42 is provided with folding line grooves 4412, and the folding line grooves 4412 is in a fold line shape, and the slide plate 449 is slidably connected to the inside of the vertical groove 4411 of the guide plate 4410. The inside of the fold line groove 4412 is slidably connected to the first slide bar 4413, and the outer wall of the first slide bar 4413 is symmetrically rotatably connected to the sleeve rod 4414. The outer wall of the sleeve rod 4414 passes through and is slidably connected to the inside of the slide plate 449. The sleeve rod 4414 is fixedly connected to the side of the nickel strip 43 with a clamp 4415, and the side of the clamp 4415 close to the nickel strip 43 is provided with an anti-slip strip, and the side of the clamp 4415 close to the nickel strip 43 conflicts with the side wall of the nickel strip 43.

[0040] When the Z-type plate 443 moves upward inside the storage bin 42, the gear shaft 445 rotates counterclockwise, the a side of the toothed belt 446 is the descending section, the b side of the toothed belt 446 is the ascending section, the second toothed clamping plate 4416 is clamped on the a side of the toothed belt 446, and the first toothed clamping plate 447 is clamped on the b side of the toothed belt 446.

[0041] In actual use of this embodiment: when two adjacent lithium-ion batteries move to the bottom of the storage bin 42, the lifter 41 contracts and drives the storage bin 42 to move downward, and the storage bin 42 moves downward and drives the nickel belt 43 inside the storage bin 42 to move downward together. When the nickel belt 43 at the bottom of the inner cavity of the storage bin 42 collides with the electrode connection point on the lithium-ion battery, the electrode connection point on the lithium-ion battery squeezes the bottom nickel belt 43 to move upward. After the bottom nickel belt 43 moves upward, it no longer squeezes the Z-shaped plate 443 downward. At this time, the first spring 444 elastically contracts and drives the Z-shaped plate 443 to slide upward on the outer wall of the limit rod 442. When the Z-shaped plate During the upward sliding of the storage bin 42, the second toothed plate 4416 is fixed to the outer wall of the storage bin 42 and is engaged with the a side of the toothed belt 446. Therefore, when the Z-shaped plate 443 moves upward, the second toothed plate 4416 pulls the toothed belt 446, causing the toothed belt 446 to drive the gear shaft 445 to rotate together. At this time, the a side of the toothed belt 446 moves downward relative to the b side. Therefore, the first toothed plate 447 engaged with the b side of the toothed belt 446 will be in an upward sliding state relative to the Z-shaped plate 443. The upward sliding of the first toothed plate 447 drives the four columns 448 and the slide plate 449 to move upward together. The slide plate 449 moves upward on the guide plate 44 When the vertical groove 4411 of 10 slides upward, the sleeve rod 4414 will be driven to move upward together. During the upward movement of the sleeve rod 4414, the first slide bar 4413 will be driven to slide inside the folding groove 4412 of the guide plate 4410. At this time, because the folding groove 4412 is in a folding line shape, when the first slide bar 4413 slides inside the folding groove 4412, it will drive the clamp 4415 to move to the side close to the nickel strip 43 through the sleeve rod 4414. When the clamp 4415 contacts the side wall of the nickel strip 43, the first slide bar 4413 moves vertically upward inside the folding groove 4412. The same principle as above, the clamp 4415 will contact the nickel strip 43 when it contacts the nickel strip 43. On the basis of the above, the nickel belt 43 is driven to move upward as a whole, so that the bottom nickel belt 43 is separated from other nickel belts 43 above it, thereby reducing the pressure on the nickel belt 43 and the resistance it encounters during its own lateral movement. Then the staff starts the conveyor belt 3, and the nickel belt 43 lifted up by the lithium-ion battery electrode connection point will be moved out to the outside of the storage bin 42 through the discharge port 451. In the process of the conveyor belt 3 driving the lithium-ion battery to move, the lower side of the transmission belt 452 will rotate under the friction of the upper surface of the lithium-ion battery, and the nickel belt 43 will be brought out under the rotation of the upper side of the transmission belt 452, thereby realizing the delivery of the nickel belt 43 to the electrode connection points of two adjacent lithium-ion batteries during welding.

[0042] The present invention uses the spacing adjustment component 45 to lift up the nickel strip 43 at the bottom of the inner cavity of the storage bin 42 by the connection between the lithium-ion battery electrodes. When the Z-shaped plate 443 moves upward in the storage bin 42, the first toothed clamp 447 realizes secondary sliding through the transmission of the toothed belt 446. The clamp 4415 drives the remaining nickel strip 43 in the inner cavity of the storage bin 42 to lift upward, thereby separating the bottom nickel strip 43 from the remaining nickel strip 43 above it, thereby reducing the downward pressure on the bottom nickel strip 43, so that the bottom nickel strip 43 can be driven and moved out of the storage bin 42 together when the lithium-ion battery moves horizontally, thereby realizing the delivery of nickel strips 43 for batches of lithium-ion batteries and achieving the purpose of automated soldering.

[0043] See also Figures 7 to 10 The spacing adjustment component 45 includes a discharge port 451 opened on the side of the storage bin 42 away from the calibrator 2, a transmission belt 452 is installed inside the storage bin 42 and below the discharge port 451, the upper and lower sides of the transmission belt 452 are tangent to the outer wall of the storage bin 42, a base 453 is installed on the outer wall of the storage bin 42, the bottom of the base 453 is fixedly connected to a sleeve 454, the bottom of the outer wall of the sleeve 454 is rotatably connected to a gear 455, the inside of the sleeve 454 is slidably connected to a second slide bar 456, and the outer wall of the second slide bar 456 is linear The array-shaped distribution is fixedly connected with a rack 457, the rack 457 and the gear 455 are meshed, the bottom of the second slide bar 456 is slidably connected with a welding pad 458, and a second spring 459 is fixedly connected between the welding pad 458 and the second slide bar 456, and the side of the welding pad 458 close to the storage bin 42 is fixedly connected with an angle plate 4510, and the side of the angle plate 4510 close to the storage bin 42 is inclined upward, and the side of the storage bin 42 close to the base 453 is rotatably connected with a guide rod 4511, and the guide rod 4511 is horizontally coplanar with the discharge port 451.

[0044] The outer wall of the sleeve 454 is symmetrically fixedly connected with the cylinder 4512, the bottom of the cylinder 4512 is fixedly connected with the bottom plate 4513, the top of the bottom plate 4513 is fixedly connected with the angled tooth plate 4514, the angled tooth plate 4514 is meshed with the gear 455 on the side close to the storage bin 42, the bottom plate 4513 is fixedly connected with the bevel plate 4515 on the side close to the storage bin 42, the bevel plate 4515 is tilted upward on the side close to the storage bin 42, and the welding pad 458 slides through the inside of the bottom plate 4513.

[0045] A plurality of welding heads are installed on the bottom of the welding pad 458 in a circular linear array, and the bottom of the welding head is coplanar with the lower surface of the bottom plate 4513 .

[0046] In actual use of this embodiment: when the top of the lithium-ion battery is attached to the nickel strip 43 and moves to the bottom of the angled plate 4510, the guide rod 4511 will adjust the direction of the nickel strip 43 when it moves out of the storage bin 42 through its tapered side wall. When the nickel strip 43 is thicker, the nickel strip 43 moved out of the storage bin 42 will first be squeezed against the inclined portion of the angled plate 4510, so that the angled plate 4510 drives the welding pad 458 to slide toward the inside of the second slide bar 456. The second spring 459 between the welding pad 458 and the second slide bar 456 is squeezed and elastically contracts. When the nickel strip 43 continues to move to be squeezed against the inclined portion of the beveled plate 4515, the beveled plate 4515 will The bottom plate 4513 is driven to move upward, and the cylinder 4512 is squeezed and contracts. The bottom plate 4513 moves upward, driving the angled tooth plate 4514 to move upward. During the upward movement of the angled tooth plate 4514, the gear 455 is engaged with the gear 455 to rotate. The rotation of the gear 455 causes the second slide bar 456 to slide downward inside the sleeve 454, so that the second slide bar 456 strengthens the pressure of the welding pad 458 on the Z-type plate 443 through the second spring 459, so that when the welding pad 458 processes the thicker nickel strip 43, it can more effectively melt the nickel strip 43 and fuse it with the connection between the lithium-ion battery electrodes, thereby increasing the welding speed of the thicker nickel strip 43. When the Z-shaped plate 443 is of regular thickness, the nickel strip 43 will be directly squeezed against the angled plate 4515 after being moved out of the storage bin 42, and the welding pad 458 will weld the nickel strip 43. However, the contraction range of the second spring 459 is smaller than that when processing a thicker nickel strip 43. Therefore, the welding pad 458 can reduce the downward pressure on the nickel strip 43 of regular thickness, thereby avoiding damage to the connection between the lithium-ion battery electrodes when the welding pad 458 melts the nickel strip 43 at high temperature.

[0047] When the nickel strips 43 of different thicknesses are moved out of the storage bin 42, the angled plate 4515 is squeezed to different heights by the beveled plate 4515, so that the welding pad 458 can apply different pressures downward to the nickel strips 43 of different thicknesses, thereby improving the efficiency of lithium-ion battery welding. At the same time, the lithium-ion battery is protected from the high temperature and high pressure of the welding pad 458 on its connection point when welding the thinner nickel strip 43, avoiding the problem of damage to the lithium-ion battery due to squeezing, and improving the service life of the lithium-ion battery after welding.
