Case Study | Distortion-Free, Precise and Easy to Integrate: INSNEX Macro Cameras Upgrade Slitting Inspection
In response to the problems of small space, fast running speed and high detection accuracy requirements in the lithium electrode sheet slitting process, INSNEX and customers jointly created a visual inspection solution based on the 7 group CIS macro camera. Through the three major technologies of time-sharing stroboscopic + high-brightness diffuse strip light, distortion-free macro imaging and minimal installation and debugging, single-station correction, width measurement and defect detection are realized, effectively adapting to the compact space of the slitting machine. The solution can clearly present defects in membrane areas, grooves, ceramics and other areas, improve measurement accuracy and system stability, reduce equipment transformation and operation and maintenance difficulties, and provide reliable support for high-speed and high-precision online testing of lithium electrode pads.
01 Introduction
In the lithium electrode sheet slitting process, the internal space of the slitting machine is small and the running speed is fast, which puts forward extremely high requirements on the accuracy and stability of the testing system.
A customers are the world's leading lithium-ion battery manufacturers, occupying important market shares in the consumer electronics and power battery sectors. This customer focuses on the production of high-energy-density, high-safety lithium-ion batteries, and its products are widely used in smart phones, notebook computers, drones, power tools and electric vehicles. Its core customers include the world's leading consumer electronics brands and many well-known electric vehicle manufacturers.
02 Customer Pain Points and Challenges
As end users become increasingly demanding battery safety, the standards for high-precision correction, high-precision width measurement, and flaw detection continue to rise. The original CCD testing system has been difficult to meet the new quality requirements and faces huge challenges.
To this end, A customers have upgraded the functions of the slitting machine equipment and put forward three core requirements for the vision inspection system:
1. High-precision testing improves product quality
During the production process of the slitting machine, surface defects are detected in real time to prevent defective products from flowing into the next process and causing additional costs;
2. Real-time correction and adjustment
Discover problems such as deviations and misalignments in the slicing process in a timely manner, and quickly adjust equipment parameters to reduce the scrap rate;
3. High-precision width measurement
Faced with different specifications of products, quickly change models to achieve high-precision width measurement without reducing production efficiency.
Based on the above requirements, the A customer vision team urgently needs an inspection system that can be installed in a narrow space of the slitting machine to improve the overall production efficiency of the slitting process.
03 Solutions
In view of the compact internal structure of the slitting machine, INSNEX and the A customer vision team jointly discussed and tested, and finally selected the 7 macro camera system to solve detection problems in narrow spaces with three major technical characteristics:
1. Time-sharing strobe + high-brightness diffuse bar light, realizing multiple inspections in a single station
Through the combination of time-sharing stroboscopic technology and high-brightness diffuse strips, a single group of macro cameras can simultaneously realize correction, width measurement and defect detection, greatly reducing the number of workstations and adapting to the limited installation space of the slitting machine.
2. Distortion-free macro imaging, significantly improved measurement accuracy
Macro cameras adopt the principle of contact imaging to eliminate the problem of edge distortion of traditional lenses, ensure authenticity and reliability of measurement data within the full field of view, and provide a stable image basis for high-precision correction and width measurement.
3. Minimalist installation and debugging, lowering operation and maintenance thresholds
The macro camera is compact and ready-to-install. It is simple and convenient to install and debug, which greatly reduces the difficulty of adjusting the vision system, and ordinary engineers can quickly complete the configuration.
04 Customer Benefit
The space advantages of camera installation are highlighted:The CIS macro camera is compact and small in size. It is easy to integrate into existing slitting machine equipment, making it especially suitable for production environments with limited space.
The accuracy of distortion-free measurement has been greatly improved:The CIS macro camera uses a cylindrical telecentric lens. 1: 1 imaging has no distortion, sharp and neat edges, and greatly improved measurement accuracy.
Time-sharing strobe and high-brightness diffused light assist defect imaging:Through the time-sharing stroboscopic technology of the CIS macro camera, the imaging effect is significantly optimized, and the defect characteristics of various areas such as film areas, grooves, and ceramics can be clearly displayed.
05 Customer Reviews
"INSNEX's macro camera is easy to install, simple to debug, and takes up little space. It does not require major changes to the mechanism. It is very suitable for use in slitting machine scenarios. At the same time, its time-sharing stroboscopic and other functions also solve difficult imaging problems."
