1. Reference execution standards: Enterprise standards/customer requirements are determined. By calibrating the black, white, and gray specifications of the baffle, programmable switching is performed, and the reflected laser is sampled and compared with the actual value through PLC. And perform automatic data numbering and Excel spreadsheet reporting, automatically calculate the standard deviation and compare it with the set accuracy standard through software. The testing machine has the advantages of strong universality, stable operation, simple operation, convenient control, and low failure rate.

The equipment mainly consists of a test bench, a moving track, a triangular calibration plate, a fixture fixing plate, a control system, etc. By using PLC to sample the reflected laser signal and compare it with the actual value, 0-100 data points are collected for automatic comparison by the data program. After sampling, the system automatically generates a number and generates an Excel report. The standard deviation is calculated by the program and compared with the set accuracy standard, and automatic judgment is made.
