Title:
部品撮像方法、部品撮像装置および同装置を備えた部品実装装置
Document Type and Number:
Japanese Patent JP5562906
Kind Code:
B2
Abstract:
A component imaging method includes: an imaging preparation step of obtaining, for each of the plurality of components, an optimum lighting intensity at which a component image, eligible for component recognition, can be obtained; a component imaging step of using a line sensor that image a line image at a predetermined timing and output the obtained line image as an image for each imaging line and a lighting device, to integrally move the plurality of components in a sub-scanning direction of the line sensor relative to this line sensor, with the plurality of components being aligned in a main scanning direction of the line sensor, and to acquire images of the plurality of components while switching a lighting intensity of the lighting device sequentially to the optimum lighting intensity of each of the components for each imaging line during the relative movement; and an image processing step of compensating a line image, which is imaged at a lighting intensity other than the optimum lighting intensities, on the basis of a ratio of the lighting intensity at which the line image is obtained and the optimum lighting intensity of each of the plurality of components of the obtained component images, for the component image of each of the plurality of components.
