High-precision Laser Online Thickness Measurement and Control Instrument for Battery Electrode Sheet Separators/Glass Fibers, capable of measuring the geometric dimensions (e.g., thickness) of the tested object and simultaneously detecting its areal density (applicable in battery and capacitor manufacturing plants).
It employs laser triangulation technology for dynamic online thickness measurement, with a computer-controlled scanning mechanism to obtain real-time thickness measurements and a distribution curve of thickness versus measurement point positions.
Utilizing this system not only enhances the automation level in the production of battery electrode sheets, films/glass/paper but also significantly improves product quality stability, reduces raw material consumption, and minimizes human interference factors and errors associated with manual measurements.
The 3D model designed by SolidWorks2017 includes a STEP format file, which can be opened using other 3D software, and the file package size is 65MB.
Working Principle
This device employs laser triangulation measurement technology to achieve dynamic online thickness measurement. The working process is as follows:
- Laser Emission and Reception: The device emits a laser beam onto the surface of the measured object, and a receiver captures the reflected beam.
- Triangulation Distance Calculation: By analyzing the reflection angle and displacement of the laser beam, the thickness of the object is calculated using trigonometric relationships.
- Dynamic Scanning and Data Processing: A computer-controlled scanning mechanism continuously scans the object, capturing real-time thickness data and generating a distribution curve of thickness versus measurement point positions.
