Vision-Guided Laser Marking with SinceVision Laser Displacement Sensors
Industry pain points and demands
In industries such as aerospace, electronics, automotive, medical, and home appliances, laser marking requires exceptional precision to handle variations in workpiece size, shape, and position. Without real-time adjustment, these inconsistencies can lead to suboptimal results, including blurry markings and inconsistent depths.
SinceVision Solution: SD-C400 Laser Displacement Sensor
01Precise Detection and High Accuracy: Detects displacements and depth changes with a ±200mm range and 0.15mm repeat accuracy, ensuring marking precision.
02Real-Time Focus Adjustment: Automatically adjusts laser focal length to maintain consistent focus, accommodating variations in workpiece surfaces.
03Compact Design with Versatility: Features a small footprint (44.4×25×20mm) and high sampling frequency of up to 1kHz, seamlessly integrating into diverse marking systems.
