Machine Vision Inspection System and Light Source Module thereof
First Claim
1. A machine vision inspection system, comprising:
- an inspection stage configured for moving an object under test;
a linear image capture module configured for grabbing an image of the object under test; and
a light source module configured for providing light beams to the linear image capture module, and the light source module comprising;
a plurality of linear light emitting diode (LED) light sources configured for providing the light beams, each of the linear LED light sources comprising a plurality of LEDs, luminance of the linear LED light sources being determined by the number of rows of the linear LED light sources, the length of each of the linear LED light sources and the cooperation of the LEDs with the same or different colors, wavelengths or sizes; and
a lampshade having a semi-cylindrical inner space, the interior of the lampshade being a semi-circular curved surface with an upward opening or a downward opening, a first disposing area and a second disposing area in the interior of the lampshade being located at both sides of the longitudinal axis of the semi-cylindrical lampshade, the linear LED light sources being disposed symmetrically in the first disposing area and the second disposing area, intervals between each two adjacent linear LED light sources in the first disposing area and the second disposing area being the same, a linear field of view of the linear image capture module being served as a reference axis, each of the linear LED light sources being disposed at a relative included angle relative to the reference axis, and an arranging direction of each of the linear LED light sources being the same with an extending direction of the semi-circular curved surface.

Abstract
In a machine vision inspection system and a light source module, the light source module includes a semi-cylindrical lampshade and linear LED light sources for provide light beams. The luminance is determined by a number of rows of the linear LED light sources, a length of each linear LED light source and cooperation of colors, wavelengths or sizes of the LEDs. The linear LED light sources are located or assembled to an interior of a curved surface of the semi-cylindrical lampshade, and arranged from a first curved-surface edge to a second curved-surface edge of the curved interior by a preset interval and a relative included angle. An arranging direction of the linear LED light sources is same to an extending direction of the interior of the curved interior. The shadow caused by illuminating from one single side may be eliminated. The present invention possesses the advantage of low cost.
