KRIVULJA - optical inspection machine for plastic components
A compact benchtop unit that feeds plastic components by vibration to a rotary table and uses a camera to verify the curve shape of every part.
Rotary table indexing with optical curve inspection
Plastic components are poured into a bowl feeder, which orients them and hands them over to a linear feeder. The linear feeder delivers the components to an electric rotary table driven by a servo motor.
On the rotary table, an industrial Basler camera with a ring light captures the component curve and sends the image to an industrial PC, where the custom-developed OPKO software compares the shape with the reference curve and decides whether the part is good. The PC passes the result to the Siemens S7-1200 PLC - good components go into the box for good parts, while defective ones are separated into a dedicated box by a Festo pneumatic cylinder.
Interface and control logic
A standard operator interface: an HMI panel with physical start/stop buttons, an emergency stop and an error acknowledge button below it.
