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.
Why flat suction cups fail on porous, textured, and irregular parts, and how bellows cups, vacuum pad grippers, and foam faced area grippers solve the difficult picks, with a face selection table.
Vacuum, mechanical, and magnetic grippers compared criterion by criterion: part material, surface condition, access, speed, and cost, with a decision matrix and honest guidance on where each technology wins.
A cobot gripper buying guide covering what makes collaborative robot tooling different, electric versus vacuum versus custom printed types, the payload weight math, and a seven point checklist for vendor conversations.
A practical vacuum gripper guide: how negative pressure gripping works, suction cup versus area surface versus custom printed types, vacuum or mechanical selection, and the five factors that decide application success.
An honest comparison of the top end of arm tooling companies, covering Piab, Coval, Schunk, OnRobot, Robotiq, Destaco, and Anubis 3D, with strengths, customization depth, and a shortlist table.
Application story: the Wedgelock, a 3D printed tool free adjustment guide for conveyor rails and sensor positioning, with squeeze and slide operation, lockable open position for multi point changeovers, and sensor specific customization.
Application story: cam activated bottle grippers and a bottle sleeve, designed and SLS printed by Anubis 3D, whose light weight allowed an alcohol bottling machine to achieve higher speed.
Application story: a 3D printed quick connect cam lock that turned a semi permanent automotive door nest into a 30 second changeover, proven with a leading Japanese automaker and evaluated for global use.
Application story: a 3D printed vacuum gripper with three independently retracting arms for vision guided picking of randomly placed conveyor products, with independent air flow per arm and integrated vacuum channels.
