Description

Technical Field

[0001] The utility model relates to the field of fill light mechanisms, in particular to a fill light mechanism for a visual camera. Background Art

[0002] Vision cameras are important inspection equipment in the field of industrial automation and are widely used in defect detection, positioning and identification of various products. In particular, vision cameras play a vital role in valve spraying machines. Valve spraying machines are devices that form images or patterns by spraying fluids (such as paint, ink, etc.). During the operation of valve spraying machines, vision cameras can be used to photograph and locate the shape and position on the substrate, so that the image or pattern formed by the sprayed fluid can be positioned and calibrated with high precision. Therefore, the camera positioning accuracy of the vision camera has a decisive influence on the performance and output quality of the valve spraying machine.

[0003] In low-light environments or reflective surfaces, the photographic effect of the visual camera will be seriously affected, because the light in these environments cannot fully illuminate the inspected object. At this time, the role of the fill light mechanism becomes particularly important. The fill light mechanism can increase the brightness of the surface of the inspected object by adding additional light, thereby enhancing the shooting and positioning effect of the visual camera. Especially in the application of valve spraying machines, since the sprayed fluid has high fluidity, more stable and clear light is required to capture the position of the material. The fill light mechanism can provide auxiliary light, so that the visual camera can shoot and locate more accurately.

[0004] In the prior art, the position and angle of the detected object in the valve spraying machine may change, so it is necessary to adjust the fill light of the visual camera. However, the fill light device used in the existing equipment generally only has a fixed fill light to fill light through a fill light plate. The fill light angle is generally vertical to the surface of the material. The surface of the material is prone to reflection under vertical illumination, which affects the shooting positioning of the visual camera, and the fill light effect at different positions on the material is poor, which affects the shooting environment of the visual camera, which is not conducive to the shooting positioning of the visual camera and affects the accuracy and reliability of the shooting positioning.
