... such as mobile phones, tablets and also many consumer electronics products combine metals and glass more and more ingeniously. In large scale or mass production these components must be measured reliably at high cycle speeds. As the products are also mostly very delicate, optical contact-free measuring systems offer great advantages here. Optical sensors ensure that all parts are perfectly aligned during assembly. For measurement procedures, the parts must not be touched. Precitec sensors are ideally suitable for dynamic, inline measurements. With line sensors a measuring line replaces the traditional measuring point, which considerably speeds up topography measurements.

应用
Measuring watch components

In watchmaking the smallest mechanical component of a clock can be inspected and measured in 3D. A line scanner CHRocodile CLS is used to do this. It can supply high resolution topographs very quickly. A chromatic measuring system is available for special applications that is co-ordinated with the measurement of micromechanical watch components. It combines a video system with a chromatic confocal measuring system within one joint optics system. The measuring system guarantees axial resolutions of less than a micron. The video system gives a direct view of the measured structure by the measuring optic.

屏幕厚度,玻璃基底上的凹坑测量

智能手机或平板电脑上那层镀过膜的、超高硬度的屏幕玻璃是通过非常精密的工艺生产出。其切割边缘需要被完全检验来判断玻璃是否能进入到下面的拼装工序中。Precitec的光学传感器能够使用不同的测头在线测量屏幕玻璃的尺寸和厚度。光学传感器通过一次扫描能同时测量玻璃的翘曲度和厚度。传感器也能测量玻璃表面那些由打磨或激光消融产生的凹坑或缺口的深度。这些凹坑会导致玻璃在往后的使用中由于受力开裂。

智能手机和平板电脑

现在的智能手机、平板电脑和其他一些电子产品都有着非常高精度的表面它们的外表一般都是由非常精细的金属和玻璃合成。这些由塑料、金属和玻璃制成的材料必须很紧密无缝地结合在一起。光学传感器能够确保在组装时所有部分都能很平整地排列在一起。在测量时,这些部件是不能被触碰的。
