Battery Welding Positioning Mechanism for Faster 3-Axis Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lithium battery top cover welding devices have low efficiency due to time-consuming separate positioning in three directions (length, width, and height) before welding, which cannot be omitted for high precision requirements.
Innovation Solution
A welding device with a material-transporting mechanism, a first positioning mechanism, and a second positioning mechanism that work together to position a workpiece in multiple directions simultaneously during transport, eliminating the need for separate post-loading positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate positioning in three directions (length, width, and height) is performed before welding, then positioning precision is improved, but positioning time increases and welding efficiency decreases
Solution Approach 1:
The patent combines multiple positioning functions into integrated positioning mechanisms. The first positioning mechanism positions the battery in the first direction, while the second positioning mechanism simultaneously positions the battery in the second and third directions. This merging of positioning operations eliminates the need for separate sequential positioning steps, thereby maintaining high positioning precision while reducing total positioning time and improving welding efficiency.
Solution Approach 2:
The positioning mechanisms perform positioning actions in advance during the material transportation process. As the material-transporting mechanism moves the battery to the welding station, the positioning mechanisms simultaneously execute positioning operations. This preliminary action ensures that positioning is completed before welding begins, maintaining precision requirements while optimizing the overall process timeline and improving efficiency.
2Manufacturing precision
If comprehensive positioning in three directions is performed, then welding precision is improved, but the complexity of the positioning system increases
Solution Approach 1:
The positioning system is segmented into two independent positioning mechanisms, each responsible for specific directional positioning tasks. The first positioning mechanism handles positioning in the first direction, while the second positioning mechanism handles positioning in the second and third directions. This segmentation allows each mechanism to be optimized for its specific function, simplifying individual mechanism design while achieving comprehensive three-directional positioning precision.
Solution Approach 2:
The second positioning mechanism is designed with multi-functionality to simultaneously position the battery in both the second direction and the third direction. This universal design reduces the total number of separate positioning components needed, as one mechanism performs multiple positioning functions, thereby reducing overall system complexity while maintaining comprehensive positioning precision.

AI summary
The present disclosure relates to a welding device, comprising a base, a material-transporting mechanism, a first positioning mechanism, a second positioning mechanism and a welding mechanism. By providing the above welding device, the material-transporting mechanism transports the battery to abut against the first positioning mechanism, and then the second positioning mechanism located at the positioning position obtains the battery abutting against the first positioning mechanism; the battery is positioned in the first direction, the second direction, and the third direction by the first positioning mechanism and the second positioning mechanism; subsequently, the battery is transported to the welding position by the second positioning mechanism, and then is welded by the welding mechanism.
