| description | The invention provides a method for quickly positioning a workpiece by a dispenser. The method comprises the following steps: recording coordinates of all Mark points of a current product in a coordinate system of equipment; s2, according to the view field range of the camera, all the Mark point coordinates input in the step S1 are listed, and all the Mark points are sorted according to the size of X coordinates; reordering the Mark points in each column according to the size of the Y-axis coordinates, and taking the X median in each column as the X-axis scanning coordinate of the current column during Y-direction scanning; calculating a scanning speed v; a workbench is controlled to scan Mark points in the Y direction; obtaining a reference coordinate (P calculation) of a Mark point by applying an image processing method; and calculating the actual coordinate (P actual) of the Mark point. The workbench can complete positioning of the whole row or the whole column through one-time movement in the same scannin |
