Abstract
The invention relates to a linear array laser detection device for steel sheet SMT laser cutting and a detection method therefor. The detection method comprises the following steps that 1, a cut SMT template steel sheet and a stretching frame are loaded on a clamping workbench; 2, a control system controls an X shaft movement assembly and a Y shaft movement assembly to carry out Gong character-shaped scanning; and 3, along a Y-shaft direction, a detection probe in a detection assembly carries out one-step scanning of distances of line segments in a detection rang D; if the surface of the detected objecte is in a detection range H of a high-precision linear array laser distance measuring sensor, a distance value is returned, and if the detected objecte part is outside the detection range H, the data of the part does is not returned so that the position of which data is not returned is determined as a cutting opening part; through determining if the data is returned or not, the position and the shape of the opening part can be determined; and through pattern recognition software of the control system, the recognized figure and an original data figure are compared so that it is determined if the SMT template steel sheet has extra/missing hole defects.
