About the outline size detection of motor gear

Gear motor products have the characteristics of "small size, large torque, and low noise". They are the lifeblood of automation and the best choice for transmission machinery companies. However, during the production process of the motor gear, there may be some deviations in the outline and contour dimensions. It is not only a waste of manpower but also difficult to judge accurately by the traditional manual detection method. The machine vision detection method can not only accurately determine its size, but also improve the degree of automation and better improve the detection efficiency.

         After experimental comparison, we found that in the visual inspection scheme, the use of a bi-telecentric lens with backlight or parallel light projection techniques, and the use of the detection method of the circumferential size, can well achieve the poor judgment of the shape and contour.

         The following figure is the actual effect of the optical system composed of ordinary lens and bi-telecentric lens:

         This solution uses a BTOS dual telecentric system. From the figure, we can see that the full projection shooting effect of the dual telecentric optical system, without vertical and horizontal parallax, completely solves the parallax problem caused by the thickness of the sample. . At the same time, it can also effectively avoid various stray reflection effects, greatly improve the sharpness of the edges of the picture, and completely solve the problem of reflection of metal edges.

         In the inspection, we use SVMS industrial intelligent vision measurement software, which can provide a variety of positioning functions, allowing the workpiece to be placed at will, and the size can be accurately detected. With the excellent characteristics of “zero distortion” of the double telecentric system, the influence of distortion on measurement accuracy can be greatly reduced.
