Description

Technical Field

[0001] The utility model relates to the technical field of welding heads, in particular to a novel square welding machine positive electrode welding head. 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 pole 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. The current intelligent welding machine positive electrode equipment is made of alloy copper. After welding is completed, the pole ear and weld particles may stick together due to high temperature, the welding head may be severely corroded and need to be replaced continuously, and the alloy copper may deform under high temperature conditions.

[0003] A welding head disclosed in the Chinese utility model patent application disclosure specification CN207358427U comprises a welding head body and a lead wire, wherein the welding head body comprises a lead wire through hole and a lead wire end portion, wherein the lead wire through hole passes through the welding head body; the lead wire passes through the lead wire through hole and is fixed to the welding head body, and one end of the lead wire passes through the lead wire end portion and protrudes outside the welding head body. One end of the lead wire passes through the outlet end and protrudes outside the welding head body, ensuring that the user can use the lead wire normally for conduction when using the welding head. Since the welding head is only composed of the lead wire and the welding head body and the lead wire is fixed to the welding head body, the welding head does not need to be provided with a transmission device specifically for transmitting the lead wire. When the lead wire is consumed, it is only necessary to replace a new lead wire and fix it to the welding head body. Therefore, compared with the prior art, the welding head is smaller in size, lower in cost, and simpler to maintain. However, the welding head is only smaller in size, lower in cost, and simpler to maintain. However, when welding, how to adjust the position of the welding head according to the position where the weldment needs to be welded, how to fix weldments of different sizes to avoid falling and perform secondary fixation on the weldment, how to take out the weldment after welding to observe whether the welding is successful, and how to avoid workers accidentally dropping and touching the weldment when removing the weldment, causing burns, and how to quickly repair and replace without affecting the work progress. Therefore, a utility model is proposed to solve the above problems. Utility Model Content
