The invention provides a high-precision pasting device and method based on CCD detection. The device comprises a product material strip feeding mechanism, a
label material strip feeding mechanism, a pasting platform, a
label sucking and pasting mechanism, a first CCD
assembly, a second CCD
assembly and a controller, wherein the first CCD
assembly is arranged between a material tray assembly and the pasting platform and located above a product material strip moving path so as to
shoot an image of a product material strip, and the second CCD assembly is arranged above a
label taking
station so as to
shoot images of labels. The product material strip feeding mechanism comprises the material tray assembly, a material pulling roller and a
servo motor driving the material pulling roller to rotate. The controller carries out contrastive analysis on the image of the product material strip and the images of the labels to control the label material strip feeding mechanism so that the labels can be accurately positioned at the label taking
station. According to the high-precision pasting device and method based on CCD detection, the two CCD assemblies are adopted to
shoot the image of the product material strip and the images of the labels respectively, contrastive analysis is carried out, and a label material strip is adjusted according to a comparison result so that the labels can be accurately positioned at the label taking
station. In this way, the labels can be sucked and pasted at high precision, and the
automation degree is high.
