Problems solved by technology

Usually the coaxial camera has a small field of view and high detection accuracy, while the side-axis is mainly used for large-format inspection, but the detection accuracy is low
For large-format laser scanning galvanometer processing, it is suitable to use the side-axis system, but the accuracy will be worse
For ultra-precision welding across dimensions of collimators, laser galvanometer scanning welding is suitable, but there are currently difficulties in welding positioning and welding quality inspection

Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] The principle of the method of visual inspection of laser welding parts based on CCD is as follows: figure 1 . The visual detection system is composed of CCD sensor, imaging objective lens, intelligent image processing software and auxiliary lighting, etc. It specifically includes multiple detectors composed of high-resolution CCD sensor 31 and imaging objective lens 32. The CCD sensor is equipped with corresponding objective lens according to the detection needs . There are two or four CCD detection devices, the field of view of four is larger, and the three-dimensional imaging is more accurate, but the cost is also higher. In this example, there are two detectors, which are respectively located on both sides of the light outlet of the dynamic focus scanning system 1, and the CCD detection system is fixed on the support frame 4 and c...
