Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery welding fixtures, in particular to a lithium battery welding assembly fixture. Background Art

[0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements, so lithium batteries have not been used for a long time. With the development of microelectronics technology, the number of miniaturized devices has increased, and high requirements have been placed on power sources. Lithium batteries have entered a large-scale practical stage. Lithium batteries refer to batteries that contain lithium (including metallic lithium, lithium alloys, lithium ions, and lithium polymers) in the electrochemical system. Lithium batteries can be roughly divided into two categories, lithium metal batteries and lithium ion batteries. Lithium metal batteries are usually non-rechargeable and contain metallic lithium. Lithium ion batteries do not contain metallic lithium and are rechargeable.

[0003] In the related art, reference may be made to Chinese patent publication number CN219561966U, which specifically discloses a lithium battery laser welding fixture. When the lithium battery laser welding fixture is used, the lithium battery is first placed on the top of the fixing seat and between the two movable plates so that the card slot and the lithium battery are aligned. By setting three card slots, the three lithium batteries can be positioned and clamped at the same time, which improves the efficiency during later welding and reduces the tediousness of frequent battery replacement. Then, the servo motor is turned on, and the output shaft of the servo motor drives the left pulley to rotate, and the left pulley drives the right pulley to rotate through the belt, and then the pulley drives the threaded rod to rotate, and the threaded rod drives the two threaded sleeves to move toward the adjacent side, so that the threaded sleeve can drive the connecting rod to move to one side, and the connecting rod drives the connecting plate to move to one side, and the connecting plate drives the transmission rod and the movable plate to move toward one side of the lithium battery, and then the movable plate can make the card slot clamped on the surface of the lithium battery, realizing the clamping operation of the lithium battery, and effectively preventing only one battery from being positioned and fixed at a time, so that the battery needs to be frequently replaced and positioned during the later welding process, which not only improves the labor intensity of the staff, but also reduces the work efficiency of laser welding.

[0004] The applicant discovered that there are deficiencies in the use of the above-mentioned lithium battery laser welding fixture: although the spacing between the movable plates can be automatically adjusted and then the lithium battery can be clamped and positioned in the slot, the above-mentioned structure can only be used to clamp and position lithium batteries of specified specifications, which reduces functionality.
