A customer who manufactures turning workpieces for the automotive industry wants to inspect the weld seams on stators for electric motors. These stators consist of a disk pack, which is fixed by three weld seams shifted by 120°. Three cameras acquire 12 images per test piece. The images are analyzed according to 10 different criteria such as seam thickness and cavities in the seam. Following a feasibility study, three DX4-205FW standard digital cameras (description on page 57) were selected for the application. They were modified and completed with additional equipment as follows:

Diffuse dome illumination Further optical elements such as prisms and mirrors

A mechanical device for gripping and positioning the stators PC control of the device

A complete PC with monitor and IO adapter Xero analysis software
