From Liquid Level to Metal Part Assembly Inspection with Vision Sensors
The SC Series Vision Sensor is featured with rich built-in vision tools for diversified inspections, integrated lens and light, and a web-based HMI to improve user experience.
To find out what improvements the SC Vision Sensors makes we show some actual application cases.
Inspection of Metal Part Assembly
In automotive industry, numerous metal parts need to be assembled. These parts are usually very small, transported in high speed on the conveyor belt. In addition, one line is assigned to multiple types of parts and the shift is quite frequent. Consequently, errors occur. To sort out the defective parts, an error-proofing inspection is required. The vision sensor has a built-in vision tool to measure the light intensity of multiple points in the FOV. All that needed is to turn on the integrated front light. By checking the light intensity of predefined positions and calculating the illuminated area, the vision sensor is able to determine whether the metal part is correctly mounted or not. Only one vision sensor is needed in the whole inspection process, and the final result OK/NG can be sent to the action part or PLC directly.
A steel manufacturer needs to sort steels during the molding process to guarantee that different steels are sent to corresponding machines correctly. Besides, before sending steels into punching machine, it is also required to check the position to ensure that it could be shaped in the punching machine accurately. The accuracy is in centimeter-level. The vision sensor can record the marking or pattern on the steel surface as a feature, and differentiate steel types and calculate the positions and angles by comparing the recorded features. Moreover, the built-in edge detection vision tool allows to measure the distance and angle between the two ends of a steel, to check whether it is identical to the mold. The inspection result can be sent to the upper computer via multiple transmission methods such as Serial port, I/O, TCP or UDP.
