Problems solved by technology
[0002] In the manufacturing process of lithium button batteries, the welding of the battery cells requires manual hand-holding of the foil bulk material and the battery cells provided by the front end. After positioning through tooling, they are placed under the ultrasonic welding machine for welding. The feeding and welding process is relatively cumbersome. Moreover, the consistency of manual welding is poor, the welding yield is low and it takes a long time, which increases the production cost
[0003] At present, in this field, there is no automatic production equipment integrating cutting, feeding, handling, pressing and positioning, and welding functions, which greatly affects the large-scale batch production of button lithium batteries

The invention discloses a battery tab welding equipment, comprising: a punching and transferring device used for punching a material strip to obtain a tab foil and transferring the tab foil to a reclaiming position; A tab foil reclaiming and attitude adjusting device for the tab foil to the reclaiming position and adjusting its attitude, and also used to transport the tab foil after the attitude adjustment to the pressing position; A cell reclaiming and attitude adjustment device for the tooling and adjusting its attitude, and also used to transport the attitude-adjusted cell tooling to the pressing position; it is used to press the tab foil and the cells on the cell tooling. A press-fit conveying device that is used for pressing and fixing the tab foil and the cell to the welding position; ultrasonic wave for welding the tab foil and the tab of the cell transported to the welding position welding device. The invention integrates the functions of cutting, feeding, handling, pressing and fixing, welding, etc., and has a high degree of automation, which can improve the yield and production efficiency of products.
Description
technical field [0001] The invention belongs to the technical field of welding, and in particular relates to a battery tab welding device. Background technique [0002] In the manufacturing and production process of button lithium battery, the welding of its cells requires manual hand-held foil bulk materials and cells provided by the front end, which are placed under the ultrasonic welding machine for welding after being positioned by the tooling. The feeding and welding process is relatively complicated. In addition, the consistency of manual welding is poor, the welding yield is low and time-consuming is long, which increases the production cost. [0003] At present, in this field, there is no automatic production equipment integrating cutting, feeding, handling, pressing and positioning, and welding functions, which greatly affects the large-scale mass production of button lithium batteries. [0004] In view of this, it is urgent to improve the existing technology, and ...
