Method for calibrating full-automatic visual inspection machines for products

The invention discloses a method for calibrating full-automatic visual inspection machines for products, and belongs to the technical field of methods for calibrating machines. By the aid of the method, the problem of poor product picking effects of existing visual inspection machines can be solved. The method includes calibrating paths of linear motors and circle centers of turntables, to be more specific, A1, shifting the linear motors to first motor points according to preset displacement b1; B1, arranging a product below each sucker; C1, determining coordinates p1 of the center points of the products in visual fields of cameras; D1, shifting the linear motors to second motor points according to preset displacement b2; E1, placing a product below each sucker; F1, determining coordinates p2 of the center points of the products in the visual fields of the cameras; G1, respectively computing coordinates of origins of the linear motors, amplification factors of the cameras and the paths of the linear motors and inputting data to computers. The method has the advantage that the products can be effectively picked by the linear motors after the full-automatic visual inspection machines are calibrated by the aid of the method.
