Problems solved by technology
This welding method, firstly, it is not easy to locate when the collector plate is turned into the shell by 90°, and the error is large; secondly, due to the difference in incoming materials, the deviation of the collector plate bent by the machine is relatively large, resulting in a large error during welding. On one side, there is a welding deviation phenomenon
Ultimately, the current collecting plate welding qualification rate is low, and the process is complicated, the cost is high, and the efficiency is low

The invention relates to a semi-automatic cylindrical current collector welding machine, comprises an operation platform, a first laser welding device and a second laser welding device arranged at both ends of the operation platform, Between that first lase welding device and the second lase welding device, a current collector welding tooling assembly is arrange, the current collector welding tooling assembly is installed on the operation platform through a moving platform, and the current collector welding tooling assembly is moved to the first laser welding device and the second laser welding device through the moving platform. The invention can realize the accurate positioning of the current collecting plate and the battery coil core, and make the current collecting plate be in close contact with the battery coil core so as to reach the state of full welding. And it can realize that the batteries do not need to be rotated, and the positive and negative current collectors can be welded successively, so as to ensure the stability of the batteries in the welding process, ensure the qualified rate of welding, and also improve the production capacity.
Description
technical field [0001] The invention relates to welding equipment for collecting discs of cylindrical electric cores, in particular to a semi-automatic welding machine for collecting discs of cylindrical electric cores. Background technique [0002] At present, in the manufacturing process of cylindrical batteries, the way of welding the collector plate is to put the collector plate into the shell first, turn it over 90° and then align the welding side with the battery cell. After welding one side, it will be folded by the machine Bend the collector plate, then turn the sequence with a robot, and weld the other side. This welding method, first of all, it is not easy to locate when the collector plate is turned into the shell by 90°, and the error is large; secondly, due to the difference in incoming materials, the deviation of the collector plate bent by the machine is relatively large, resulting in a large error during welding. On one side, welding deviation occurs. Ultim...
