This case is the customer in the LCD panel detection line in order to carry out the 2D code information on the LCD panel traceability, after reading the completion of the uploaded to the control system of the host computer;
In the specific code reading process, the manipulator grabs the LCD panel and places the workpiece to be detected, so that the2Dcode sends a command signal under the code reader; The code reader automatically captures the clear image, automatic decoding, the decoding time is controlled within 1s, after the decoding is successful, the content of the code or NG information is transmitted to the host computer, and the NG picture is saved as the basis for information traceability;
Application scenarios: LCD panel 1 * 1mm DM code, 232 communication mode, including positive image and dot code and normal code mixing, the code may have a teardrop-like stain on it;
This example highlights the ability of a stationary barcode reader to decode small codes
