Imaging system for component axial centering detection apparatus

Abstract

The invention relates to an imaging system for an axial centering detector of a component, belongs to a machine vision imaging system, and solves the problems of complex structure, trivial operations, poor precision and influence on centering operation of the prior imaging system. In the imaging system, a supporting arm is positioned on a pedestal and can be adjusted up and down relative to the pedestal; an electronic camera and an optical lens which are in screwed connection with each other are fixed at one end of the supporting arm, and a plane mirror and a light source which are fixed on the pedestal are connected to the other end of the supporting arm; geometrical centers of the optical lens, the plane mirror and the light source are on the same plane; an imaging plane of the plane mirror and the electronic camera is angulated at 45 DEG; and emergent ray of the light source is parallel to the imaging plane of the electronic camera. The imaging system is simple to operate, does notrequire superabundant adjustment and conversion, can simultaneously show images of an object in two vertical directions, does not influence the spatial structure and the operation process of the centering object, improves the image quality and the deviation measurement precision, and is convenient for image processing in the late stage so as to improve the centering precision of electromechanicalproducts in automatic production, assembly and debugging.

Description

technical field [0001] The invention belongs to an imaging system of machine vision, and in particular relates to an imaging system of a component axial centering detection device, which can be used for accurate axial centering detection of two needle-shaped components in automatic production, assembly and debugging of electromechanical products. Background technique [0002] In the mechanical adjustment of electromechanical products, it is often necessary to adjust the axes of two needle-shaped objects in space to coincide, that is, to center. For example, in the chip picking operation of electronic packaging equipment, the ejector pin lifts the chip from the silicon disk, and the suction nozzle sucks up the ejected chip from the top of the ejector pin along the axial direction of the ejector pin. During this process, if the center of the thimble does not coincide with the center of the suction nozzle, the chip will roll over or fall. For this reason, in the installation a...
