It was very hard to make precise laser marking by manually adjusting screws and very difficult especially when screws are with the drive(edge). Production becomes very slow and time consuming by manually adjust the screws and make laser marking. Customer of our OEM partner wanted to develop a complete automation solution to detect multiple screws, then detect edge(driver) or each crew, dynamically build template and perform laser marking. Target was to have x4 times production compare to manual process.
The project includes couple of challanges;
- Find an edge or screw head driver angle and according to that create laser marking template on runtime.
- System should not have any limitation of number of screws on the vision area.
- Calibration of Visiona and Camera to create precised laser marking template in mili meter from specific camera angle and pixels ratio
- Rotary position and precision
- Live camera macro view
