In the field of 3C, the requirements for precision dispensing are getting higher and higher, which requires real-time detection of the glue height to achieve closed-loop control of precision dispensing. Because the glue has a variety of transparent and non-transparent materials, and the glue profile is more complex, and the tilt Angle is large, the traditional laser sensor can not accurately measure the height of the glue profile. The D82 probe has the largest measurement Angle in the world and can be used to measure various glue profile heights, especially in the round hole glue height detection has a unique advantage.

The measuring range of 2mm sensor, under the static environmental test for 3 hours, the fluctuation of the measuring result is about ±0.25um, and the effect is good. The result is the comprehensive result of the whole measuring system, plus the deformation of the measured object itself affected by the change of environmental temperature, the sensor can actually do higher.
