The present invention relates to an upper and lower CCD camera alignment guiding method. The method comprises the following steps: taking a photo of a product by using an upper CCD camera and taking aphoto of a substrate by using a lower CCD camera respectively for two times to determine the deviations between the actual positions of the product and the substrate, and the preset positions of theproduct and the substrate; according to the deviation between the actual position and the angle of the product and the deviation between the actual position and the angle of the substrate, confirmingthe position and angle of the deflection required for the product to be attached to the substrate; by means of mapping, determining a compensation angle of the product rotating relative to the substrate; and rotating the product by the certain angle around the rotation center. Compared with the prior art, the method provided by the present invention has the beneficial effects that: by means of mapping, the deviation of two coordinates is confirmed, and then compensation is performed by rotating the angle, so that the precision of product attachment is improved.
Description
technical field [0001] The invention relates to the technical field of visual guidance and positioning of mounting and transporting equipment, in particular to an alignment guidance method for upper and lower CCD cameras. Background technique [0002] Due to the rapid development and wide application of electronic products, the requirements for the quality and craftsmanship of circuit board products are getting higher and higher. The early manual placement of electronic components, foam, and labels can no longer meet the current people's requirements for electronic products. More and more electronic products are produced using surface mount technology, so the requirements for the visual guidance of such production equipment to achieve high-precision placement are also getting higher and higher. The traditional method is for the operator to put the product to be placed into the positioning fixture, supplemented by industrial camera observation, manually move the material to b...
