Technical Field

[0001] The invention relates to the field of battery production devices, in particular to a sodium battery welding device. Background Art

[0002] With the vigorous development of the new energy industry, sodium-ion batteries are also booming in addition to the mainly used lithium-ion batteries. The principle of sodium-ion batteries is similar to that of lithium batteries, relying on the reversible migration of sodium ions between the positive and negative electrodes to realize the charging and discharging of the battery. Compared with lithium-ion batteries, sodium-ion batteries differ mainly in positive and negative electrode materials, electrolyte solutes and current collectors. The positive electrode materials of sodium-ion batteries are iron-manganese-copper / nickel ternary system and phosphoric acid system, and the negative electrode material is hard carbon. The electrolyte solute uses sodium hexafluorophosphate instead of lithium hexafluorophosphate, and the current collector uses cheaper aluminum foil. Therefore, sodium-ion batteries have become the motivation for various companies to develop and produce due to their good cost advantages.

[0003] After the production of sodium-ion batteries, it is necessary to connect the motors of multiple batteries together through metal sheets. Patent application number: CN202122637838.X discloses a welding device for sodium battery manufacturing, including a base, a guide groove extending forward is opened on the top of the base, and a support plate is connected to the inner wall of the guide groove for sliding forward and backward. The top array of the support plate is provided with sodium batteries, and the left and right sides of the top of the base are fixedly connected with a feed rack, and the inner wall of the feed rack is connected to the metal sheet for sliding left and right. By placing the sodium battery array on the top of the support plate, and then sliding the support plate toward the rear side along the bottom wall of the guide groove, the rear side of the support plate is abutted against the rear end face of the guide groove. At this time, the sodium battery is located directly below the welding head and corresponds one to one. Then, the metal sheet is welded to the battery through the welding head. However, this type of device can only weld one side of the battery to the metal sheet at a time, and cannot weld both sides of the battery to the metal sheet at the same time.
