Along the axial direction of the lens barrel body 11, the outer diameter from the light inlet to the light outlet gradually increases, so that the lens barrel body 11 forms a trapezoidal barrel that penetrates along the axial direction of the lens barrel body 11; the interior of the trapezoidal barrel is set in this way to form a semi-enclosed air environment, which can better prevent air flow, reduce optical path jitter, and reduce air temperature difference, so that the optical path medium between the light inlet of the observation lens 2 and the welding wire material 5 is more stable, and the accuracy of image recognition is improved. In addition, by setting the reflective structure 13, the loss of effective light can be reduced, and the outer edge effect of the solder ball on the welding wire material 5 can be seen more clearly.
