Assistance with laser marking focus adjustment | Height measurement of SD-C400
SinceVision SinceVision
For those who want to suppress blurriness in printing and uneven depth caused by variations in the height and position of the workpiece, we introduce examples of positioning and focus adjustment in laser marking using the SinceVision SD-C400 laser displacement sensor.
Even within the same lot, differences in dimensions, shapes, and installation positions can occur. The distance between the work surface and the marking head is acquired in real-time. Changes in surface height are detected and utilized for focus adjustment on the marking device side and control according to processing depth. The settings for laser output and irradiation time tailored to the material and printing conditions are supported by distance information.
It supports a measurement range of ±200mm, a repeatability accuracy of 0.15mm, and a maximum sampling rate of 1kHz. With a compact housing of 44.4×25×20mm and multiple communication methods, it is also suitable for integration into devices with limited installation space.
By coordinating height measurement and processing control, it supports the clarity of characters and shapes and the uniformity of the finish. Please consult us about implementation tailored to your device configuration and target workpiece.
