[0002] At present, in a vision detection device, a coaxial light source is generally directly used to obliquely irradiate the end face of a workpiece to be detected, so as to facilitate the detection of the top surface of a columnar workpiece (such as a drill bit, a screwdriver, etc.). However, the illumination effect of the diffused light of the coaxial light source is poor, and it cannot well illuminate the top end of the workpiece to be detected, especially the head of a rotary needle and the head of a cross screwdriver, resulting in shadows at the end of the workpiece to be detected, thereby reducing the detection accuracy.

[0053] Optionally, the first support member 31 is L-shaped and includes a horizontal plate mounted on the support plate assembly 1 and a vertical plate fixedly connected to the horizontal plate. An absorbent layer 311 is provided on the side surface of the first support member 31 close to the detection hole 101. The second support member 32 is detachably mounted on the vertical plate. The absorbent layer 311 can prevent the image of the second support member 32 itself from being refracted into the detection camera 6 through the beam splitter 4, so as to improve the detection accuracy.
