It regards above all the recovery of a spot welder with rectified current, a round vibrating base and 2 straight vibrators, which were mounted on a machine that welded a product by now out of production.
For the project, we thought of a future reuse of as many components as possible taking into account the life of each product, therefore the specific equipment was consistently reduced compared with the past.
So, we chose to use a small robot for the manipulation of pieces.
The machine is fully automated: the plate and the stud bolt are oriented and fed by means of two circular vibrators.
The robot takes the plate and puts it on the lower electrode and then the stud bolt is put on the upper electrode and hold by a venturi system.
At the end of welding it will be downloaded into a suitable container.

As it's a detail for the car industry, the machine is equipped with all the required monitoring devices: first of all, the measurer of welding current, plus, being a projection welding, the clew crushing is monitored by a potentiometric sensor and the welding pressure is kept constant by a proportional valve combined with a load cell.
The possible waste is selected and disposed in a different container.
The production provides more than 600 pieces/hour.
