Welding Image Inspection Rhythm for Faster Multi-Point Quality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The detection of welding quality in battery production processes is time-consuming, disrupting the production line efficiency and increasing costs when multiple welding parts require imaging and analysis, especially when space is limited for multiple image acquisition apparatuses.
Innovation Solution
A welding quality detection system that allows simultaneous or partially parallel movement and analysis of image acquisition apparatuses and products, optimizing the detection process by adjusting the detection rhythm to reduce overall time without increasing camera count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image acquisition, processing and analysis are performed sequentially for each welding part, then welding quality can be detected accurately, but production efficiency is reduced and the production beat is disrupted
Solution Approach 1:
The system performs preliminary actions by moving the image acquisition apparatus to the next detection position and acquiring the next image while the current image is being processed and analyzed. This overlapping of preparation actions with processing actions reduces total detection time without compromising quality assessment accuracy.
Solution Approach 2:
The system maintains continuous useful action by ensuring that the image acquisition apparatus is constantly engaged in either acquiring images or moving to the next position, with no idle waiting time. The parallel execution of image acquisition, movement, and processing creates a continuous detection flow that matches production speed.
2Loss of time
If multiple image acquisition apparatuses are deployed to detect multiple welding parts simultaneously, then detection time is reduced, but device complexity and cost increase
Solution Approach 1:
The system applies dynamics by making the image acquisition apparatus movable rather than stationary, allowing it to dynamically reposition between different welding parts. This single apparatus can assume multiple detection positions sequentially, achieving multi-point detection capability without deploying multiple fixed cameras, thus reducing system complexity while maintaining fast detection.
3Measurement precision
If the image acquisition apparatus moves to different positions to capture multiple welding parts, then comprehensive quality detection is achieved, but detection process complexity increases
Solution Approach 1:
The image acquisition apparatus is designed with multi-functionality, serving as both the detection sensor and the positioning mechanism. The same apparatus that captures images also moves to different positions, eliminating the need for separate positioning systems for each detection point. This universal design simplifies the overall detection process while enabling comprehensive multi-point quality assessment.

AI summary
A welding quality detection system includes: an image acquisition apparatus, a transmission apparatus, a controller, and a processor. The image acquisition apparatus is configured to acquire a first image of a first welding part of a to-be-detected product. The transmission apparatus is configured to move the to-be-detected product or the image acquisition apparatus to a new position. The image acquisition apparatus is configured to acquire, a second image of a second welding part of the to-be-detected product. The controller is configured to indicate the processor to analyze the first image and the second image. The processor is configured to analyze, according to the controller, the first image and the second image at least partially in parallel with the movement of the to-be-detected product or the image acquisition apparatus to the new position, to determine welding quality of the first welding part and welding quality of the second welding part.
