The problem, and the fix.
Problem
Each module takes 24 bolts. Operators drove them with torque tools and another operator checked by eye, but bolts missed on the night shift kept turning up at the customer’s incoming inspection.
Volume called for a third shift, but experienced night-shift operators were hard to find.
Solution
Three fastening stations sit along the module conveyor, with two HG-C16-10 cobots at each station splitting the bolts from either side. Torque and angle from the nutrunner are stored for every bolt under the module serial number.
A camera on the same wrist photographs each joint right after fastening, which brought the separate inspection station into the cell. On the side where people do wiring, area scanners placed according to the risk assessment slow the robots when someone approaches.
Result
Zero bolts were missed in the first three months. The line moved from two shifts to three without adding skilled operators, and people now handle wiring and final checks.
