AGME designs and manufactures special purpose machines for screwing automotive components. It has recently made a rotary transfer to screw car seat tracks. The screwing process is done in 12 seconds thanks to the automation of most operations.
The machine is composed of a four station rotary transfer with:
– One bed base and one circular plate with four work stations
– One set of 4 tools with 3 positions in each tooling
– One Screwing unit
– Pneumatic components: Pneumatic progressive starter, general electro valve and pneumatic presostate
– Electric components: general cabinet with power elements, control by “Siemens S7-300” automaton and tactile operating board
– Guarding: fixed guardings and photoelectric barrier
In the first station the following operations are performed: upper track manual feeding, latch positioning and upper track control through laser sensors. After these operations in the second station there are two screws automatic loading and screwing together with a torque and angle control.
Then the distance between the components is controlled in the third station as well as the ok parts marking. Finally, in the fourth station there is an ok parts automatic eduction. The Nok parts will be taken to a Red box.
