PCB high-precision intelligent positioning method based on digital micromirror

The invention provides a PCB high-precision intelligent positioning method based on a digital micromirror, and the method comprises the steps: obtaining images of various electronic components and PCBs, making a data set of the electronic components and the PCBs through the preprocessed images, and carrying out the positioning of the electronic components and the PCBs according to the names of positive and negative pins of the various electronic components in the data set and the names of insertion round holes corresponding to the positive and negative pins on the PCBs. Establishing a mapping relationship between the positive and negative pins and the insertion round holes; and performing target detection on the image in the data set by using an improved Faster RCNN to obtain the coordinates of the positive and negative pins of the electronic component and the coordinates of the corresponding insertion round holes in the PCB, and transmitting the data to a mechanical arm so as to finish the accurate insertion
