[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-2This utility model provides a wire feeding mechanism for a battery cell string welding machine, including a material carrier platform 1. A wire feeding assembly 2 is provided on one side of the top of the material carrier platform 1, and a drive cutting assembly 4 is provided on the other side of the top of the material carrier platform 1. A processing assembly 3 is provided in the middle of the top of the material carrier platform 1. The processing assembly 3 includes a lifting platform 31, a first rectangular frame 32, and a second rectangular frame 33. The first rectangular frame 32 and the second rectangular frame 33 are fixedly installed on both sides of the top of the lifting platform 31. U-shaped parts 34 are symmetrically arranged on the upper and lower sides inside the first rectangular frame 32, and a servo motor 35 is fixedly installed on the top of the first rectangular frame 32. A pressure roller 38 is rotatably installed inside the first U-shaped part 34, and connecting ears 39 are symmetrically fixedly connected to the front and rear sides of the first U-shaped part 34. A lead screw 36 and a sliding shaft 37 are respectively arranged on the front and rear sides inside the first rectangular frame 32. The upper end of the lead screw 36 is connected to the servo motor 35. The output end of 5 is fixedly installed, and the upper and lower outer walls of the lead screw 36 are provided with opposite threads. The lead screw 36 is threadedly connected to the connecting ear 39, and the sliding shaft 37 is slidably connected to the connecting ear 39. The front and rear sides of the rectangular frame 33 are symmetrically provided with U-shaped parts 310, and the front side of the rectangular frame 33 is fixedly installed with a servo motor 311. The pressure roller 314 is rotatably installed inside the U-shaped part 310, and the upper and lower sides of the U-shaped part 310 are symmetrically fixedly connected with connecting ears 315. The upper and lower sides of the rectangular frame 33 are respectively provided with lead screw 312 and sliding shaft 313. The front end of the lead screw 312 is fixedly installed with the output end of the servo motor 311, and the front and rear outer walls of the lead screw 312 are provided with opposite threads. The lead screw 312 is threadedly connected to the connecting ear 315, and the sliding shaft 313 is slidably connected to the connecting ear 315.

[0023] In this technical solution, the welding wire to be welded to the battery cell is passed through two pressure rollers 38 and 314. The servo motor 35 drives the lead screw 36 to rotate. Since the upper and lower outer walls of the lead screw 36 have opposite threads, the two U-shaped parts 34 can be moved towards each other through the lead screw 36, the sliding shaft 37, and the connecting ear 39. This adjusts the distance between the two pressure rollers 38 and compacts the welding wire vertically. The servo motor 311 drives the lead screw 312 to rotate. Since the front and rear outer walls of the lead screw 312 have opposite threads, the two U-shaped parts 310 can be moved towards each other through the lead screw 312, the sliding shaft 313, and the connecting ear 315. This adjusts the distance between the two pressure rollers 314 and compacts the welding wire horizontally, ensuring the overall straightness of the welding wire and thus not affecting the subsequent welding operation.

[0024] In some technical solutions, such as Figure 1 , Figure 3 and Figure 4As shown, the drive cutting assembly 4 includes a U-shaped frame 41 and a cutting tool 42. The front and rear sides of the U-shaped frame 41 are provided with through holes 43. The upper and lower sides of the inside of the through holes 43 are slidably connected to sliders 44. A drive roller 45 is rotatably installed between the two horizontal sliders 44. A drive motor 410 is fixedly installed on the rear side of the rear slider 44. The output end of the drive motor 410 is fixedly installed to the rear end of the drive roller 45. A vertical shaft 411 is fixedly installed inside the through hole 43. Springs 412 are sleeved on the upper and lower sides of the vertical shaft 411. The two ends of the springs 412 are fixedly connected to the inner walls of the sliders 44 and the through hole 43, respectively. The cutting tool 42 is located diagonally above the two drive rollers 45.

[0025] In use, the welding wire is passed through two drive rollers 45, and the spring 412 drives two vertical sliders 44 to move towards each other, so that the two drive rollers 45 clamp the welding wire. The drive motor 410 drives one drive roller 45 to rotate, thereby realizing the function of moving the welding wire and ensuring that the welding wire can reach the cutting point smoothly.

[0026] In some technical solutions, such as Figure 1 and Figure 4 As shown, a mounting plate 46 is fixedly installed on the upper part of one side of the U-shaped frame 41, and support ears 48 are fixedly installed on the front and rear parts of one side of the U-shaped frame 41. A rolling cutter 49 matching the cutting cutter 42 is rotatably installed between the two support ears 48. A hydraulic cylinder 47 is fixedly installed on the top of the mounting plate 46. The output end of the hydraulic cylinder 47 passes through the mounting plate 46 and is fixedly installed on the top of the cutting cutter 42, and the cutting cutter 42 is located above the rolling cutter 49.

[0027] In use, the welding wire to be cut is supported by the rolling cutter 49, and the hydraulic cylinder 47 drives the cutting cutter 42 to move downward to cut the weld, realizing the support-type single-blade cutting function. This can ensure the smoothness of the cut and prevent the upper part of the welding wire from being taut and deformed, resulting in a better cutting effect.

[0028] In some technical solutions, such as Figure 2 As shown, a matching rubber sleeve 316 is fitted and fixedly connected to the first pressure roller 38, and a matching rubber sleeve 317 is fitted and fixedly connected to the second pressure roller 314.

[0029] During use, the pressure of the pressure rollers 316 and 317 on the welding wire is reduced by the rubber sleeves 316 and 317, thus preventing damage to the welding wire.

[0030] In some technical solutions, such as Figure 1 and Figure 5 As shown, the wire feeding assembly 2 includes a vertical plate 21 and several wire coils 22. Several support shafts 23 are fixedly installed at equal intervals on the front side of the vertical plate 21, and the wire coils 22 are sleeved on the support shafts 23.

[0031] In use, the welding wire can be easily released via the welding wire coils 22 on each support shaft 23.

[0032] In some technical solutions, such as Figure 1 As shown, several support legs 5 are fixedly installed at equal intervals along the outer edge of the bottom of the loading platform 1.

[0033] During use, the stability of the fabric filament mechanism is ensured by multiple support legs 5.

[0034] Working principle: During use, the end of the welding wire on the welding wire coil 22 is passed sequentially through two pressure rollers 38, two pressure rollers 314, and two drive rollers 45. A spring 412 drives two vertical sliders 44 to move towards each other, causing the two drive rollers 45 to clamp the welding wire. A drive motor 410 drives one drive roller 45 to rotate, thus achieving the function of moving the welding wire. A servo motor 35 drives a lead screw 36 to rotate. Because the upper and lower outer walls of the lead screw 36 have opposite threads, the lead screw 36, sliding shaft 37, and connecting lug 39 can drive two U-shaped parts 34 to move towards each other, thus moving the welding wire. The vertical compaction process is performed by servo motor 311 driving lead screw 312 to rotate. Since the lead screw 312 has opposite threads on its front and rear outer walls, the two U-shaped parts 310 can be moved towards each other through lead screw 312, sliding shaft 313 and connecting lug 315 to perform horizontal compaction of the welding wire, ensuring the overall straightness of the welding wire. The rolling cutter 49 supports the welding wire to be cut, and the hydraulic cylinder 47 drives the cutting cutter 42 to move downward to cut the weld, realizing the support-type single-blade cutting function, which can ensure the smoothness of the cut and prevent the upper part of the welding wire from being taut and deformed.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
