Description
Technical Field
[0001] The utility model relates to the technical field of new energy manufacturing, in particular to a novel negative electrode welding head for a large surface welding machine. Background Art
[0002] Most of the existing soft-pack lithium-ion battery welding technologies are laser welding or ultrasonic welding. The above two welding methods cannot effectively solve the welding difficulties between copper and aluminum. The welding stability effect is poor. The temperature at the ear during the battery cell cycle is high, which can easily cause the electrolyte inside the battery cell to decompose and fail, affecting the battery cycle life.
[0003] The welding head disclosed in the Chinese utility model patent application disclosure CN212652865U, although the device radiates ultrasonic energy to all sides during the welding process, instead of destroying the welding result like the trapezoidal tooth pattern, to achieve a better ultrasonic welding effect, and at the same time, the smoothness around the arc has better conduction uniformity for ultrasonic wave conduction from large surface to small surface, from the root of the tooth to the top of the tooth, breaking the conduction unevenness of the previous trapezoidal tooth pattern and improving the service life of the welding head, but the existing device does not solve the problem that the weldment cannot be welded due to its irregular shape and the side of the weldment cannot be welded. A large amount of toxic gas is easily generated when welding the weldment, and these toxic gases are inhaled into the body by the operator, which can easily cause physical discomfort to the operator. The negative electrode welding head is extremely hot after use, and it is easy to cause burns to the operator if it is directly replaced. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0028] How this utility works:
[0029] During use, the fixed motor 2 drives the fixed rotating shaft 3, so that the moving seat 4 drives the negative electrode welding head 10 of the welding machine to rotate and move, which is convenient for welding the weldment. The driving seat 6 drives the negative electrode welding head 10 of the welding machine to move up and down through the lifting hydraulic rod 5. At the same time, the driving motor 7 rotates the driving rotating shaft 8 to rotate the bracket 9 and the negative electrode welding head 10 of the welding machine. At the same time, the moving seat 4 continues to move inside the rotating slide rail, so that the negative electrode welding head 10 of the welding machine can rotate and move at multiple angles, which is convenient for welding irregular-shaped weldments, solving the problem that the traditional welding machine cannot weld irregular-shaped weldments due to different shapes and cannot The problem of continuing welding on the side of the weldment is solved by adjusting the angle of the negative electrode welding head 10 of the welding machine according to the shape of the weldment so that weldments of different shapes can be welded, which greatly enhances the practicality of the welding machine. The toxic gas generated during welding can be sucked into the adsorption box 12 through the fan 13 and the pipeline 15, and then the toxic gas is filtered and adsorbed through the activated carbon box 14, and then the filtered toxic gas is discharged, which solves the problem that a large amount of toxic gas is easily generated when welding the weldment, and these toxic gases are inhaled into the body of the operator, which easily causes the operator to feel uncomfortable, and achieves the effect of being able to weld. The effect of absorbing and filtering the toxic gas generated during welding of the weldment greatly reduces the harm to the operator caused by the toxic gas generated during welding. By sliding the baffle 23 forward, the driving motor 7 rotates the driving shaft 8 to rotate the bracket 9 and the negative electrode welding head 10 of the welding machine by 180 degrees, so that the negative electrode welding head faces downward, and then the support seat 17 is moved upward by the supporting hydraulic rod 16, and the left clamping plate 22 is moved to the right by driving the hydraulic rod 21, so that the left clamping plate 22 and the right clamping plate 20 clamp the negative electrode welding head, and then the negative electrode welding head 10 of the welding machine is moved upward by the lifting hydraulic rod 5. The negative electrode welding head 10 of the welding machine is separated from the negative electrode welding head. At the same time, the support motor 18 drives the support shaft 19 to rotate the negative electrode welding head 180 degrees, and then the left clamping plate 22 is driven to the left by the hydraulic rod 21, so that the negative electrode welding head falls into the collection box 24, and then the opening is closed by sliding the baffle plate 23 forward, which solves the problem that the negative electrode welding head is very hot after use and is easily burned if it is directly replaced.
