Description
TECHNICAL FIELD
[0001] The utility model relates to light source adjusting device technical field especially relates to fabric weft straightener multidimensional light source adjusting device. BACKGROUND
[0002] In the fabric weft straightening process, the core purpose of multi-dimensional adjustment of light is to overcome the limitation of traditional single light source, so as to improve the detection accuracy, adapt to complex working conditions and realize intelligent production. The optical characteristics of different fabrics (such as silk, denim and elastic fabric) are significantly different. High-reflective fabric (such as coated fabric) is prone to mirror reflection noise, which needs to be suppressed by adjusting the angle, color temperature and diffuse scattering mode of the light source.
[0003] Therefore, it is necessary to use a multi-angle adjusting mechanism to adjust the angle and position of the light source, and to work cooperatively with a linear array light source and a linear array camera, which is suitable for high-speed, high-precision and continuous motion surface detection scenarios. Since the weft straightener is running at high speed, it will generate some vibration, which will be transmitted to the multi-angle adjusting mechanism installed on the weft straightener. The multi-angle adjusting mechanism is driven by a push rod motor. The continuous vibration of the push rod output shaft will affect its accuracy through mechanical wear, signal interference and control instability, especially in high-speed and high-precision applications. This will cause the angle adjustment to deviate. When the object moves quickly, a small angle deviation between the light source and the camera will cause the image to stretch or distort. In order to ensure the imaging effect, it is necessary to increase the maintenance cost of the multi-angle adjusting mechanism. UTILITY MODEL CONTENT
