Abstract

The invention relates to a system and a method for detecting an electronic element on a circuit board. The method comprises the steps of pre-building a standard image with a calibration point and a standard area, capturing an image of the circuit board to be detected, correcting the circuit board image according to the calibration point, finding a corresponding comparison area in the corrected circuit board image according to the standard area, performing designated image treatment and image comparison on the standard area and the comparison area according to the type of the electronic element, and correspondingly recording production sequence numbers of the standard area and the circuit board to generate a prompt message when the image processing results of the standard area and the comparison area are not matched. Therefore, the technical effect that the efficiency of detecting the electronic element on the circuit board is improved can be achieved.

Description

technical field [0001] The invention relates to a detection system and a method thereof, in particular to a detection system and a method for detecting electronic components on a circuit board on a production line. Background technique [0002] Traditional circuit board detection methods mostly use human visual inspection, and the circuit boards that need to be detected are detected one by one by manpower on the electronic components on the circuit board. The camera function in the system captures the alignment target on the circuit board, and then prints or displays the image of the alignment target obtained on the monitor, and finally uses the measurement tool to manually print out or display the image The target image is detected, and according to the detection result, it is judged whether the circuit board to be tested is a good board or a defective board. [0003] Using the detection method of the aforementioned circuit board not only has poor operating efficiency, but...
