This groundbreaking equipment is meticulously engineered for objects requiring ultra-efficient, high-precision, non-contact flatness and warpage testing. Its unparalleled accuracy ensures optimal performance and reliable measurements in all applications.
Applicable Industries: Our Precision Flatness and Warpage Measurement System is indispensable across a diverse range of sectors including cell-phone glass faceplates, glass panels, cell-phone housings, aluminum and other metal sheets industries, automotive parts, PCB circuit boards, and the broader electronics industry, among others.
Principle of Flatness Test: Delve into the meticulous process of assessing flatness, where precision meets technological prowess.:
- Take points P1 through P9 respectively on the work-piece surface, ensuring comprehensive surface coverage.
- The 9 points fitting into a precisely fitted surface provide the foundation for accurate measurements.
3. To determine flatness, identify the maximum positive and negative deviations from the fitted surface. Summing the absolute values of these deviations provides the flatness measurement.
Principle of Warpage Testing: Understanding the intricacies of warpage begins with methodical point analysis.
Take 9 points on the work-piece surface-P1 through P9-to ensure an exhaustive analysis.
- Fit a plane using points P1, P7, and P9. Determine the distance of all 9 points from this plane, finding the maximum deviation for the #1 value.
- Fit a plane with P7 , P9 , P3 , and find the distance of all 9 points to this plane, recording the maximum deviation as the #2 value.
- Fit a plane with P9, P3, and P1, then find the distance of all 9 points to this plane, recording the maximum deviation as the #3 value.
- Fit a plane with P3, P1, and P7, then find the distance of all 9 points to this plane, recording the maximum deviation as the #4 value.
- Find the maximum value among the #1~#4 measurements; this maximum is the warpage.
Advantages of Our Equipment in the Industry: Setting new benchmarks in efficiency and precision.High Efficiency::The ITN-L3-540 system, equipped with three high-precision laser probes, operates like three machines in one, delivering unprecedented speed and efficiency in measurements.
As demonstrated in actual projects, our system measures flatness, warpage, and thickness of cell-phone glass faceplates simultaneously, achieving a remarkable throughput of 17,000 pieces in 11 hours. The speed can be further optimized based on loading and unloading rates.
High Accuracy (Standard Gauge):
Repeatability: 0.003mm
Spot Relativity: 0.02mm
- Specialized Capability: Measuring thin glass face-plates of cell-phones with thicknesses less than 0.5mm.
- Thin glass, prone to bending and deformation under its own weight, yields different measurements depending on the fixture support. Our fully supportive design mitigates these variations, ensuring consistent accuracy.
Our innovative design fully supports the thin glass, addressing the challenge of measurement inaccuracies due to bending-an issue unsolved by other manufacturers in the market.
Basic Functions: An array of features to cater to diverse measurement needs.:
1. Scans the work-piece through laser probes, enabling detailed analysis and calculation of flatness, warpage, and thickness.
;
2. The measurement data and judgment results are directly displayed as either GOOD or NO GOOD on the computer display screen, providing a clear and immediate indication of whether the work-piece is qualified or not. This feature also ensures timely classification.
3. Measurement results can be effortlessly transferred to Excel, making data handling and analysis straightforward.
;
4. Programmable and capable of saving programs, this system allows you to recall and use pre-saved programs for direct measurements, significantly saving the operator's time and effort.
;
5. Suitable for measuring objects of different sizes, users can design fixtures according to the dimensions of their objects, ensuring versatile application.
;
6. Stage travel range: 500*400mm, providing ample space for various measurement tasks.
;
7. Example: For a glass size of 161.19x75.80mm, the table can accommodate 12 pieces at one time using the fixture, enhancing efficiency.
;
8. Test cycle time: approximately 25 seconds per cycle (including loading and unloading), ensuring quick and efficient operations.
