Two UR10e cobots operate on the soft-top assembly line for the FIAT cabrio 500 model. The first cobot performs two different operations; Using a pad supported by a special pick-up device, the UR10e cleans and prepares the primer track, on which the adhesive to fix the soft-top to the frame is subsequently applied. The second operation is a quality control, where a vision system checks the geometric continuity and dimensions of the adhesive band.
The second cobot works in synergy with an anthropomorphic robot. Once the soft-top has been assembled, it is opened on a special support and then picked up by the robot. At this point, the second UR cobot runs a size check (through a vision system) on the soft-top frame to ensure the conformity of the dimensions. Once conformity has been ascertained, the soft-top is removed from the line by the anthropomorphic robot.
This application offers a series of productivity and quality advantages. The cobots ensure that the adhesive extrusion is correct and check the dimensions of the soft-top frame.
On the door assembly line for the FIAT 500 electric cabrio car, a UR10e cobot has been configured to press-set 10 blind pop rivets, which secure the boot hinge reinforcements to the boot frame. The operator loads the tailgate frame and hinge reinforcements on to the workstation, then leaves the cobot to position and press-set the rivets.
The application provides productivity and ergonomic benefits. At the same time, constant monitoring of the workstation input and output parameters ensures higher and consistent process quality.
For this application, the car body reaches the workstation with the hood mounted in a closed position and the hinge screws inserted by the operators on the previous station. Once the hood geometry has been established, the cobot (a UR10) moves into position and tightens the 4 screws to the correct torque. The main advantages of this application are quality, efficiency and ergonomics, given that the hood reaches the station in a closed position, making correct tightening extremely difficult. Since the hinge screws to be tightened are not visible, the operator could easily miss one or make an incorrect tightening. The cobot also improves the ergonomics of the operation, freeing the operators from working in uncomfortable or awkward positions.
