Battery Production Line Switching Using Real-Time Product Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional battery production lines require extensive downtime and material waste during model switching due to long tool switching times and inefficient production line adjustments.
Innovation Solution
A battery manufacturing method and system that utilizes a controller to obtain product information in real-time, enabling production equipment to switch to producing new-model products based on specific conditions, reducing waiting times and material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the production line waits for downstream processes to complete before switching models, then production consistency is maintained, but model switching time increases and productivity decreases
Solution Approach 1:
The upstream production equipment performs model switching in advance before downstream processes complete. The controller detects product information upstream and triggers fixture switching and model change before the entire production line finishes current model production, allowing downstream processes to naturally transition without waiting
Solution Approach 2:
The system implements dynamic model switching where different production equipment can switch to different models at different times based on real-time product information detection. The controller dynamically adjusts the switching timing for each equipment based on downstream process status, enabling flexible and adaptive production line reconfiguration
2Manufacturing precision
If the entire production line shuts down for model switching, then complete fixture replacement ensures accuracy, but production downtime increases
Solution Approach 1:
Fixture switching is performed preliminarily by upstream equipment before downstream processes complete. The controller detects product information and triggers fixture changes in advance, allowing the production line to maintain continuous operation while completing model switching
Solution Approach 2:
The production line is segmented into independent switching units where each equipment can perform model switching independently. Upstream equipment switches fixtures and models separately from downstream equipment, allowing parallel switching operations without requiring complete line shutdown
3Productivity
If material inventory is increased to support model switching, then production continuity is maintained, but material waste increases
Solution Approach 1:
The controller continuously detects product information from the production line and uses this feedback to determine optimal switching timing. This real-time feedback mechanism allows the system to switch models based on actual production status rather than pre-planned inventory buffers, reducing the need for excess material inventory
Solution Approach 2:
Model switching is triggered preliminarily when product information is detected upstream, allowing the system to prepare for model changes before materials are consumed. This advance detection enables just-in-time switching without requiring large material inventories

AI summary
A battery manufacturing method is applied to the battery manufacturing system. The battery manufacturing system includes a controller and production equipment. The battery manufacturing method includes: during product production by production equipment in any process of a battery production line, obtaining, by the controller, product information, where the production equipment is equipment corresponding to any process in a battery group production line; and in a case that the product information meets a product switching condition, controlling, by the controller, the production equipment to switch to producing a new-model product.
