[0028] Working principle: Place the lithium battery pack to be welded on the placement table 5. Then place the foil on the electrode. Next, drive the welding head 3 close to the foil by the electric push rod 2 and then perform welding. At the same time, before welding, the operator can pull the bolt 15 outward by the magnet 16 until the bolt 15 leaves the tooth groove of the gear 13. At this time, the gear 13 is released from the limit. Then, the limit plate 8 can be lifted upward. At this time, the limit plate 8 slides upward through the slide plate 7 and the rear seat 9 until the limit plate 8 is at the same height as the lithium battery pack. Then push the magnet 16 forward. The magnet 16 can then drive the bolt 15 to move forward until the bolt 15 is inserted into the tooth groove of the gear 13. At this time, the gear 13 can be limited, thereby limiting the height of the rack 11 and the slide plate 7, and further fixing the limit plate 8. By setting the limit plate 8, the limit height can be freely adjusted. In this way, when the electric push rod 2 is damaged or misoperated, the welding head 3 can be prevented from falling and hurting people. The utility model prevents the welding head 3 from falling when the electric push rod 2 is damaged or misoperated through the mechanism of the limit plate 8 and the bolt 15, avoiding injury, improving the safety of the equipment, protecting the operator, and through the cooperation of the magnet 16 and the bolt 15, the height of the limit plate 8 can be easily adjusted to adapt to lithium battery packs of different heights. The operation is simple and convenient, reducing the complexity of manual adjustment. At the same time, the height of the limit plate 8 can be freely adjusted to adapt to lithium battery packs of different specifications and heights, increasing the flexibility and adaptability of the equipment. When adjusting the height of the limit plate 8, the set slide plate 7 can slide in the workbench 4. The slide plate 7 can drive the mounting rod 18 to move. The mounting rod 18 can then drive the mounting frame 19 and the filter plate 20 to move. In this way, after the limit plate 8 is raised, the set filter plate 20 is also raised. In this way, the filter plate 20 can block the welding point, thus avoiding harm to the operator. In the utility model, when the height of the limit plate 8 is adjusted, the filter plate 20 rises accordingly, effectively blocking the strong light and sparks at the welding point, preventing harm to the eyes and skin of the operator, and improving the safety during the operation process. At the same time, the design of the slide plate 7 driving the mounting rod 18 and the filter plate 20 to move realizes the linkage between the height adjustment of the limit plate 8 and the position adjustment of the filter plate 20, reducing the manual operation steps and improving the operation efficiency. At the same time, the automatically lifting filter plate 20 reduces the need for the operator to wear additional protective equipment during the welding process, making the operation more convenient and comfortable. The filter plate 20 not only protects the operator but also prevents damage to other equipment caused by the spatter and high temperature generated during the welding process, extending the service life of the equipment.
