Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The relative movement between the passing roller and the pole piece during transmission leads to deviations in the labeling position, causing abnormal labeling in the pole piece detection process.
Innovation Solution
A method and device that determine a first distance from a mark hole to an image edge in the pole piece image, followed by calculating a second distance to the labeling position, using camera positions and parameters to improve labeling accuracy by minimizing the impact of relative movement, and controlling the labeling based on a calculated delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pre-measured distance is used for labeling, then labeling process is simple, but relative movement between passing roller and pole piece causes labeling position deviation
Solution Approach 1:
The patent uses a visual detection system to detect the actual position of the pole piece during transmission, and feeds back this position information to dynamically adjust the labeling position. This closed-loop feedback mechanism compensates for the relative movement between the passing roller and pole piece, ensuring accurate labeling despite the simplicity of the transmission process.
Solution Approach 2:
The patent performs preliminary detection of the pole piece position using a visual detection system before the labeling operation. By detecting the mark hole position in advance and calculating the actual transmission distance, the system prepares the correct labeling position information beforehand, preventing position deviation caused by relative movement during the labeling process.
2Measurement precision
If visual detection system is used to detect pole piece defects, then defect detection capability is improved, but relative movement causes deviation between actual transmission distance and pre-measured distance
Solution Approach 1:
The visual detection system not only detects defects but also measures the actual position of the pole piece and mark hole during transmission. This position measurement feedback is used to calculate the actual transmission distance and adjust the labeling position accordingly, resolving the contradiction between defect detection capability and labeling position accuracy.
Solution Approach 2:
The patent introduces an intermediary calculation process that uses the detected mark hole position as a reference point. By measuring the distance from the mark hole to the labeling position and comparing it with the pre-measured distance, the system identifies and compensates for deviations caused by relative movement, ensuring both defect detection accuracy and labeling position precision.
3Device complexity
If pre-measured distance is used without considering relative movement, then device complexity is reduced, but labeling position deviation occurs
Solution Approach 1:
Instead of complicating the device with multiple measurement systems, the patent uses a simple visual detection system to capture the mark hole position and implements a feedback mechanism that calculates the actual transmission distance. This software-based feedback approach maintains device simplicity while achieving accurate labeling position compensation.
Solution Approach 2:
The patent replaces complex mechanical distance measurement systems with a visual detection system and computational approach. By using image processing to detect the mark hole position and calculating the actual transmission distance through software, the system achieves high precision without increasing mechanical device complexity.

AI summary
This application discloses a pole piece labeling control method and device, electronic equipment, and a storage medium. The method comprises: acquiring a pole piece image of a target pole piece, where the pole piece image includes a pole piece mark hole image; determining a defect detection result according to the pole piece image; determining a first distance according to the pole piece mark hole image; determining a second distance according to the first distance; determining a labeling delay of the target pole piece according to the second distance; and controlling the labeling of the target pole piece according to the labeling delay and the defect detection result. The real-time position condition of the pole piece transferred on a compression roller is identified through the pole piece mark hole image, so that the labeling delay determined based on the pole piece mark hole image is less affected by the relative movement of the pole piece and the compression roller, the accuracy of the labeling delay is improved, and the labeling position based on the labeling delay is more accurate.
