Embodiment Construction
[0019] The detection method of the present invention is different from the sensor detection method on the market now, and the meanings of the inspection precision, inspection range and distance are explained as follows:
[0020] Detection accuracy: established as image 3 In the coordinate system shown, it is possible to know the emission light equation of all luminous tubes and the coordinates of the intersection with the position equation of the strip. Among all the intersection coordinates, the maximum value of the difference between adjacent coordinates is the detection error of the system, that is, the detection accuracy . When the position of the strip changes, the coordinates of the intersection point will change, and the detection accuracy will change with the position of the strip.
[0021] Detection range: the maximum range that the detection device can detect when the position of the strip changes.
[0022] Detection distance: the distance between the photoelectri...
