Apparatus for acquiring image of inner race of deep groove ball bearing, and image acquisition method
By combining the synchronous lighting method between the striped light source and the bright field light source, multiple detection cameras and the light-shading light source are used to obtain a complete image of the inner ring channel of the deep groove ball bearing, which solves the problems of low detection efficiency and high cost in the prior art, and achieves defect detection with high recognition rate.

AI Technical Summary
Technical Problem
In the prior art, the inner ring channel detection efficiency of deep groove ball bearings is low and costly. Manual detection damages vision and has a large hysteresis of noise detection, making it impossible to effectively identify shallow pits in the channel.
Method used
By combining striped light sources and bright field light sources, multiple detection cameras and light shielding light sources are used to obtain a complete image of the inner ring channel of the deep groove ball bearing, including the middle and edge areas, to improve the image recognition rate.
Benefits of technology
It reduces detection costs, improves detection efficiency and quality, effectively identifies channel defects, and avoids visual damage and waste of raw materials.

Abstract
Disclosed are an apparatus for acquiring an image of an inner race of a deep groove ball bearing and an image acquisition method. The apparatus comprises a race midsection detection station and race edge detection portions. The race midsection detection station has a first detection camera and a first shading light source, and the first detection camera cooperates with the first shading light source to acquire a midsection area image of an inner race of a deep groove ball bearing. The race edge detection portions have respective second detection cameras and respective second shading light sources, and the respective second detection cameras cooperate with the respective second shading light sources to acquire an upper edge area image and a lower edge area image of the inner race of the deep groove ball bearing. The image acquisition apparatus and method of the present invention enable comprehensive acquisition of images of an inner race of a deep groove ball bearing, thereby acquiring a dent-type defect image with a high resolution, and improving detection quality for subsequent dent defect detection of the inner race of the deep groove ball bearing.
