When a product leaks air faster than the pump can pull it, vacuum stops working. Needle grippers solve that by penetrating instead of sealing, and the trade-off is a mark you have to design around.
On a depalletizing cell the pallet arrives as it arrives, so the load pattern drives the tooling. How layer picking, mixed SKU loads and slip sheets change end-of-arm tool design.
A vacuum switch turns the vacuum level in a gripper circuit into a pick confirmation signal. How setpoints, hysteresis, sensing location and zoning decide whether EOAT catches a failed pick.
The actual method for sizing a vacuum gripper: four inputs, real cup force numbers with sealing diameters, the top lift formula with a worked example, shear pick rules, layout spacing, and when to move from a spider tool to a plated gripper.
A visual guide to robot gripper types: vacuum cups, foam area grippers, mechanical fingers, bag and bottle grippers, magnetic modules, internal spreaders, and soft grippers, with photos and a selection table.
The design rules we apply as an EOAT manufacturer: payload budgeting, moment loads, ISO 9409 mounting, vacuum routing, SLS design rules with first party tolerance data, and a practical checklist.
