Abstract
An anti-slip end-effector for transporting a workpiece, which is configured to be attached to a robotic arm, includes: a workpiece-supporting area for placing a workpiece thereon for transportation; at least one front protrusion disposed at a distal end of the workpiece-supporting area for engaging an edge of the workpiece to restrict movement of the workpiece placed on the workpiece-supporting area beyond the front protrusion; and at least one anti-slip protrusion disposed in the workpiece-supporting area for contacting and supporting the backside of the workpiece, said anti-slip protrusion having a top face having a static friction coefficient of 1.0 or more as measured against the backside of the workpiece, and having a surface roughness of less than 0.4 μm.

An anti-slip end-effector for transporting a workpiece, configured to be attached to a robotic arm and comprising:
- a workpiece-supporting area for placing a workpiece thereon for transportation, said workpiece having a backside having a glossy finish;
- and
- at least one anti-slip protrusion disposed in the workpiece-supporting area for contacting and supporting the backside of the workpiece, said anti-slip protrusion having a top face having a static friction coefficient of 1.0 or more as measured against the backside of the workpiece, and having a surface roughness of less than 0.4 μm,
- wherein the top face of the at least one anti-slip protrusion is constituted by a convex surface having a spherical curvature with a radius of 2.5 mm or more, and is made of polybenzimidazole.
