[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution: a lithium battery cell welding equipment, including a frame 1 for supporting the upper part, a positioning component 2 for positioning the lithium battery in the inner cavity of the frame 1, an adjustment component 3 for adjusting the welding and dust removal position in the inner cavity of the frame 1, and two sets of adjustment components 3 are symmetrically arranged. The upper end of the outer side of one set of adjustment components 3 is provided with a welding mechanism 4 for welding the positioned lithium battery, and the upper end of the outer side of the other set of adjustment components 3 is provided with a dust removal mechanism 5 for removing dust during the welding process, and the dust removal mechanism 5 is located directly above the welding mechanism 4.

[0023] The frame 1 provides stable support, and the positioning component 2 can reliably position the lithium battery to avoid displacement during welding and ensure welding accuracy. The two symmetrical adjustment components 3 can flexibly adjust the positions of the welding mechanism 4 and the dust removal mechanism 5 to meet the needs of different welding scenarios. The welding mechanism 4 can accurately weld the positioned lithium battery, while the dust removal mechanism 5 located directly above the welding mechanism 4 can promptly handle the dust generated during the welding process to prevent dust from affecting the welding quality and working environment.

[0024] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the positioning component 2 includes a connecting shaft 21, which is fixedly connected to the center of the inner cavity of the frame 1 on one side. A spring 22 is slidably connected to the outer side of the connecting shaft 21, and several sets of springs 22 are provided.

[0025] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, a movable column 23 is fixedly connected to the end of the spring 22 away from the frame 1. The movable column 23 is elastically connected to the frame 1 through the spring 22, and several sets of movable columns 23 are symmetrically arranged. A positioning ring 24 for positioning the lithium battery is fixedly connected to one end of the movable column 23.

[0026] With the help of the elastic action of the spring 22, the movable column 23 can drive the positioning ring 24 to move flexibly, which can adapt to lithium batteries of different sizes, achieve stable positioning, prevent the lithium battery from shifting during welding, ensure welding accuracy, and at the same time, the elastic connection can avoid rigid compression damage to the lithium battery.

[0027] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the adjustment component 3 includes a first fixed column 31. The first fixed column 31 is fixedly connected to one side of the frame 1. The top of the first fixed column 31 is fixedly connected to a first motor 32. The end of the first motor 32 near the frame 1 is rotatably connected to a first screw 33, and the first screw 33 is rotatably connected to the inner cavity of the frame 1.

[0028] When the first motor 32 is working, it can drive the first screw 33 to rotate, providing power for the position adjustment of the subsequent welding mechanism 4 and dust removal mechanism 5. The screw drive can achieve precise position control, making the welding and dust removal operations more accurate and meeting the welding needs of different positions.

[0029] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the welding mechanism 4 includes a first movable column 41, which is threaded to the outside of the first screw 33 and slidably connected to the inner cavity of the frame 1. A second motor 42 is fixedly connected to one side of the upper end of the first movable column 41. One end of the second motor 42 is rotatably connected to the second screw 43, which is rotatably connected to the inner cavity of the first movable column 41.

[0030] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the inner cavity of the first movable column 41 is fixedly connected to the first guide shaft 44 on both sides, the outer side of the first guide shaft 44 is slidably connected to the second movable column 45, and the second movable column 45 is threadedly connected to the outer side of the second screw 43. The bottom end of the second movable column 45 is fixedly connected to a welding head 46 for welding lithium battery cells.

[0031] The first movable column 41 can move along the frame 1 under the drive of the first screw 33 to adjust the lateral position of the welding mechanism 4; the second motor 42 drives the second screw 43 to rotate, which can drive the second movable column 45 to move along the first guide shaft 44 to adjust the longitudinal position of the welding head 46, realize the multi-directional movement of the welding head 46, flexibly cope with different welding points, and the first guide shaft 44 ensures the stability of the second movable column 45 when it moves, thus improving the welding quality.

[0032] As one implementation method in this embodiment, please refer to Figures 1-4As shown, the dust removal mechanism 5 includes a third moving column 51, which is threaded to the outside of the first screw 33 symmetrically arranged on the other side, and the third moving column 51 is slidably connected to the inner cavity of the frame 1. The inner cavity of the third moving column 51 is rotatably connected to the third screw 52, ​​and the outer side of one end of the third screw 52 is rotatably connected to the synchronous belt 53. The inner cavity of the synchronous belt 53 away from the third screw 52 is rotatably connected to the second screw 43. The outer side of the third screw 52 is threadedly connected to the dust blowing head 54, and the dust blowing head 54 and the welding head 46 move synchronously under the action of the synchronous belt 53.

[0033] The third moving column 51 moves with the first screw 33 as it rotates, which can adjust the lateral position of the dust removal mechanism 5. The synchronous belt 53 makes the third screw 52 and the second screw 43 rotate synchronously, thereby making the dust blowing head 54 and the welding head 46 move synchronously, ensuring that the dust blowing head 54 is always aligned with the welding position, and effectively and timely removing the dust generated during the welding process, avoiding the dust from affecting the welding quality and working environment. At the same time, the synchronous movement design improves the dust removal efficiency and targeting.

[0034] Working principle: When the equipment is working, the lithium battery is first placed in the positioning component 2. The lithium battery will contact the positioning ring 24, causing the movable column 23 to move towards the frame 1. The spring 22 is compressed. Using the rebound force of the spring 22, the movable column 23 drives the positioning ring 24 to tightly press against the lithium battery, completing the positioning and fixing of the lithium battery. Next, according to the welding position requirements, the first motor 32 in the adjustment component 3 is started. The first motor 32 drives the first screw 33 to rotate. Since the first moving column 41 is threadedly connected to the first screw 33 and slidably connected in the inner cavity of the frame 1, the first moving column 41 will move laterally along the frame 1, thereby driving the welding mechanism 4 to adjust its lateral position as a whole. At the same time, the rotation of the first screw 33 on the other side will drive the third moving column 51 to move laterally in sync, causing the dust removal mechanism 5 to also adjust its lateral position. When it is necessary to adjust the longitudinal position of the welding head 46, the second motor 4 in the welding mechanism 4 is started. 2. The second motor 42 drives the second screw 43 to rotate. The second moving column 45, being threadedly connected to the second screw 43 and slidably connected to the first guide shaft 44, will move longitudinally along the first guide shaft 44, thereby driving the welding head 46 to adjust to a suitable welding height and longitudinal position. While the second screw 43 rotates, the third screw 52 will rotate synchronously with the second screw 43 through the transmission action of the synchronous belt 53. Since the dust blowing head 54 is threadedly connected to the outside of the third screw 52, ​​the dust blowing head 54 will move longitudinally with the rotation of the third screw 52. And because of the synchronous transmission of the synchronous belt 53, the movement of the dust blowing head 54 and the welding head 46 are consistent, and it is always directly above the welding head 46. Subsequently, the welding head 46 performs welding operation on the positioned lithium battery. During the welding process, the dust blowing head 54 works synchronously to suck or blow away the dust generated during welding in a timely manner, completing the welding and dust removal operations.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
