First, software testing instructions:
1. Detection content: mainly detect the right and wrong of the printed characters on the surface of the calculator;
2. Accuracy.
Second, mechanical action cycle time: 3 ~ 4s per piece, software detection: 2 ~ 3s per piece.
Third, visual configuration: CCD: one In-sight camera.
Fourth, Features and Advantages:
1.IN-SIGHT comparison, can distinguish whether the characters are intact; In the character missing/error detection is by setting a standard template (OK character), each detection to detect the character and the standard template to compare, distinguish whether the character is intact;
2. Equipment detection has high stability and simple operation.
