In some bin picking applications, you may have to flip parts to present it always from the same side to the next processing step (machine, conveyor,...)
Bin picking application may be done with asymmetric flat parts like those presented here below:
Those part have different contour if the lay on their "A" side or "B" side.
In such cases, 2 part models have to be defined to perform the picking.
In some application it is necessary to flip the part to present it always from the same side to the next processing step (machine, conveyor,...).
Here is a method to flip the part using a "V" shaped JIG.
- The gripper drop the part in the V shaped JIG on its B slide.
- The robot flip the part.
- The gripper pick the part on its A side.
It may be possible to drop the part in a position where it will directly fall on its A side. This can speed up flipping process.
Such part flipping operation take some time and will therefore reduce throughput capability.
Here below is an estimation of the effect of this process on possible through put:
- Green: possible
- Yellow: challenging
- Red: Nearly impossible
