Embodiment Construction

[0037] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0038] Figure 1 to Figure 8 It shows a light source device for machine vision in the present invention. The machine vision detection system is specifically: using a CCD camera to convert the detected target into an image signal, and sending it to a dedicated image processing system. According to the pixel distribution and brightness, color and other information into digital signals, the image processing system performs various operations on these signals to extract the characteristics of the target, such as area, quantity, position, length, and then output the results according to the preset tolerance and other conditions, including size, angle , number, qualified / unqualified, yes / no, etc., realize automatic identifica...

Abstract

The invention discloses a light source device for machine vision and a method for changing the angles of light sources. The light source device comprises a shell, luminous panels and angle adjusting prisms. The luminous panels are installed at the upper portion of the shell. The angle adjusting prisms are detachably installed at the lower portion of the shell. The angle adjusting prisms are located under the luminous panels so as to adjust the angles of emergent light rays of the luminous panels to the lighting angles. According to the technical scheme and the light source device for machine vision, based on vertical light rays, the angle adjusting prisms for deflecting light rays are additionally arranged, the emergent angles of all the light rays are changed into the same angle, and therefore ring light at different lighting angles is achieved. Ring-light light sources at different lighting angles can be achieved through the angle adjusting prisms at different angles, light ray intersection does not exist when the light rays are deflected, and the uniformity of original light spots is not affected.

Description

technical field [0001] The invention relates to the field of illumination light sources, in particular to a light source device for machine vision and a method for changing the angle of the light source. Background technique [0002] At present, in the machine vision light source detection system, in order to meet different conditions of use, it is necessary to purchase ring light devices with different angles, and the angle range of the ring light devices is generally 0° to 90°. It can be seen that non-standardized and non-universal ring light devices have problems such as poor versatility, high production costs, and high purchase costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a light source device for machine vision and a method for changing the angle of the light source. [0004] The technical solution adopted by the present invention to solve the technical problem is to construct a light source devic...
