Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module assembly apparatuses struggle to accurately recognize the position of battery cells for electrical connection due to lack of illumination, leading to potential welding defects from foreign matter contamination.
Innovation Solution
A battery module assembly apparatus equipped with a vision unit and illumination portion, including a transfer unit, vision unit, and washing unit, which scans and cleans the battery cell before bonding to ensure accurate positioning and removal of foreign matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a vision type camera is used to scan the battery module to set bonding coordinates, then the bonding position can be identified, but without a light source to illuminate the battery module, it is difficult to accurately recognize the position of the battery module
Solution Approach 1:
The patent introduces a light source that illuminates the battery module before the vision camera scans it. This preliminary illumination action ensures that the camera can accurately capture the position and shape of the battery module, enabling precise recognition of bonding coordinates without compromising measurement precision.
2Productivity
If the battery module is transferred to the welding unit, then bonding can be performed, but the battery module may be contaminated by foreign matter such as dust during transfer, causing welding defects
Solution Approach 1:
The patent introduces a cleaning unit that removes foreign matter from the battery module before it reaches the welding unit. This preliminary cleaning action prevents contamination during transfer, eliminating welding defects while maintaining continuous bonding process productivity.
3Manufacturing precision
If the vision camera scans the battery module to set coordinates, then bonding can be performed at the correct position, but without accurate position recognition, bonding defects may occur
Solution Approach 1:
The patent uses a light source to illuminate the battery module before scanning, enabling the vision camera to accurately capture position information. This preliminary illumination ensures that the camera can precisely recognize bonding coordinates, directly improving both measurement precision and manufacturing precision.
Solution Approach 2:
The vision camera scans the battery module to detect its actual position and shape, then feeds this information back to adjust the bonding coordinates. This feedback mechanism ensures that bonding is performed at the correct position based on real-time position recognition, eliminating bonding defects.
