Embodiment Construction

[0033] Aiming at the deficiencies of the prior art, the present invention proposes a multi-finger robot end effector with a variable grasping range and a method. By using two motors to drive the main shafts that move independently, one is used to drive the end effector to lift The other one is used to drive the end effector to perform opening and closing movement. The two movements are carried out independently, which can realize the movement with variable grasping diameter and grasping height. In addition, in the present invention, a plurality of evenly distributed circular motion guide grooves are provided to make the equally uniformly arranged fingers move synchronously, avoiding the phenomenon of movement stagnation, and the present invention will be described in detail below with reference to the accompanying drawings.

Abstract

The invention provides a multi-finger robot end effector with a variable grabbing range and a method. The multi-finger robot end effector comprises at least two robot fingers, a finger grabbing range adjustment device and a finger grabbing and stretching device, wherein the finger grabbing range adjustment device controls the robot fingers to move transversely and adjusts the grabbing range of the robot fingers; and the finger grabbing and stretching device controls the robot fingers to move longitudinally and enables the robot fingers to grab or stretch. Compared with the prior art, the problem that end effects with different specifications need to be replaced when a conventional robot end effector needs to grab shape-varying objects is solved.

Description

technical field [0001] The invention relates to a multi-fingered robot end effector with variable grasping range and a method. Background technique [0002] The end effector of the robot is installed on the end flange of the robot, and realizes simple grasping actions through electric drive or pneumatic means, and is used to grasp the grasped objects and perform related action tasks. The range of motion of the grasping action of the existing robot end effector is fixed, and it can only grasp objects of a fixed size. When it is necessary to grasp larger or smaller objects, it is necessary to replace the robot end effector with other specifications. Contents of the invention [0003] The technical problem solved by the present invention is: to overcome the deficiencies of the prior art, to provide a multi-fingered robot end effector and method with a variable grasping range, and to solve the problem that the existing robot end effector needs to grasp shape-changing objects ...
