Inspection principle

Copper foil has low surface oxygen characteristics, can be attached to various substrates, such as metals, insulating materials, etc., and has a wide temperature range. Mainly used in electromagnetic shielding and anti-static. The conductive copper foil is placed on the surface of the substrate and combined with the metal base material. It has excellent conductivity and provides electromagnetic shielding effect. There will be some defects in the production process of copper foil. KEYE TECH has developed a surface defect inspection system for copper foil.

The system uses the "backlight" imaging method to perform real-time synchronous scanning through a CCD line-scan camera which installed on the production line. The CCD transmits the collected image data to the multi-function image processing software KVS-AI. Analyze and judge the surface image characteristics of copper foil through software. Real-time inspecting,sorting and processing of defects such as pinholes and edge cracks.

The schematic diagram of its structure is as follows:

system function

1. Convenient operation

The operation is simple, just click "Start", "Stop" to complete all operations. 

2. High stability

It can work continuously in a high-temperature plant environment.

3. High-precision inspection

The solution can detect 99.5% of defects over 0.02 square millimeters, meeting the ever-increasing quality requirements of customers.

4. Remote database

Accurate quality statistics can be performed on each roll of material produced. Detailed defect records (size and location) and statistics provide convenience for the adjustment of production process and equipment status; offline analysis is used for subsequent slitting and quality management, which can effectively guarantee product quality.

5. Positioning mark function

Every time a roll of product is produced, the system will automatically count the surface defects of this roll of product, and at the same time print out a statistical label, affix it to this roll of product, and distribute it to downstream users along with the product. In this way, users can grade the products through the labels on each roll of products, which can be effectively used to allocate different quality requirements.

6. Input and output alarm

When the system inspects a defect, it will give an audible and visual alarm, and other I/O outputs can also be added to the system.

7. Report statistics and printing

Report statistics and print the EXCEL defect list, which is convenient for users to do further inquire, analysis, and file create.
