Problems solved by technology

[0006] However, when the workpiece has a cylindrical shape, the distance between the base and the workpiece does not change even if the workpiece rotates, so it is difficult to accurately detect the relative displacement (slippage) of the workpiece

Abstract

The present invention provides a manipulator for grasping a cylindrical object, the manipulator having: a base portion having a base surface facing the object, the base portion being rotatable around a first rotation axis, and The first rotation axis extends in a direction perpendicular to the base surface; a holding mechanism is provided on the base portion to hold the object; a sliding detection mechanism detects the object relative to the sliding detection of a gripping mechanism; and a notification unit that notifies a detection result of the slipping detection mechanism having a function of opening and closing the object by opening and closing in a direction intersecting the first rotation axis. At least two gripping parts are gripped, and the sliding detection mechanism is provided on the gripping parts.

Description

technical field [0001] The present invention relates to manipulators. Background technique [0002] Conventionally, since the threaded plate used as a fixing method of the workpiece (object) in the NC processing machine uses a special method, it is difficult to automate the loading and unloading of the workpiece. Therefore, when setting the workpiece on the threaded plate, the worker manually attaches the workpiece to the threaded plate. In addition, the operator visually confirms the seating of the workpiece on the threaded plate. At present, in order to greatly improve the working efficiency of workers, the development of robots that can automate workpiece setting is being promoted. [0003] As the automation of robots advances, idling of the workpiece after the workpiece is seated on the threaded plate becomes a problem. That is, if the workpiece is idling with the rotation of the processing machine side while the workpiece is gripped by the robot arm, scratches, defor...
