GRIPPING DEVICE AND INDUSTRIAL ROBOT
Document Type and Number:
Japanese Patent JP2022162465
Kind Code:
A
Abstract:
To provide a gripping device and an industrial robot, which can surely catch and grip workpiece having a shape difficult to be caught and workpiece having a slippery surface.SOLUTION: A gripping device 1 includes: an elastically deformable partition film 12; a vacuum pump 8 (deformation means) which elastically deforms the partition film 12; and a cylindrical gripping section 11A which extends from a peripheral edge of the partition film 12, elastically deforms toward a center axis direction accompanying elastic deformation of the partition film 12, and wraps workpiece. The gripping section 11A is brought into contact with the workpiece, so that a sealed space is formed among the workpiece, the gripping section 11A, and the partition film 12. A volume of the sealed space is increased due to elastic deformation of the partition film 12, so that a negative pressure is generated in the sealed space. The gripping device 1 surely catches and grips the workpiece with friction force applied between the workpiece and the gripping section 11A and suction force caused by the negative force generated in the sealed space formed among the workpiece, the gripping section 11A and the partition film 12.SELECTED DRAWING: Figure 2
