Kinemetrix uses a servo controlled dispense head and 3D vision to meet the challenge of accurately dispensing FIPG material onto a narrow flange and inspecting the results. The electric vehicle inverter housing required a narrow, well controlled bead. This was accomplished with a dispensing head driven by a robot servo motor acting as a 7th axis so that dispensing rates could be tightly coupled to robot speed. Machine vision locates each housing in 3 dimensions and the path is adjusted to keep the bead in the center of the flange and to avoid the standoff changes that can change cross-sectional shape. Automated nozzle cleaning and health checks ensured repeatable nozzle flow.
After dispensing, the bead is verified for position, width and height. The part is scanned with a robot-mounted sensor that provides 3-dimensional data.
The process is error-proofed at the material input station. Built-in scanning of employee badges ensure that only trained operators are loading material. Scanning of the material code verifies a match before the load door can be opened.
