Driving device for robot gripper

Abstract

The invention discloses a driving device for a robot gripper. The driving device comprises a mounting flange, a first bracket, a second bracket, a motor, a first lantern ring, a second lantern ring, a third lantern ring and a fourth lantern ring. A first spring is arranged between the first lantern ring and the limiting block; the third lantern ring winds the top of the first lantern ring through a first connecting rope; the bottom of the first lantern ring is hinged to a first gripper and a second gripper; a second slide bar is inserted onto the fourth lantern ring; a wedge block is connected to the inner side of the slide bar and an arc-shaped plate is fixedly connected to the outer side; the shaft of the motor is inserted into the fourth lantern ring; a base plate is also fixedly connected below the fourth lantern ring; the shaft of the motor is fixed below the base plate through a fixed bolt; a fourth spring sleeves the fixed bolt; the fourth spring is located between the motor shaft and the base plate; and the first gripper is wound on the arc-shaped plate through a second connecting rope. The driving device disclosed by the invention can improve the defects in the prior art and can be applied to a plant which is not driven by compressed air, and the gripper is more conveniently adjusted.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to a driving device for a robot claw. Background technique [0002] Industrial robots are important automation equipment for modern manufacturing that integrates multidisciplinary advanced technologies such as machinery, electronics, control, computers, and sensors. They have the advantages of both humans and machines in terms of structure and performance. The robot gripper is a key part of an industrial robot. The robot gripper is not only a sensor that actively senses the working environment information, but also an actuator at the end of the robot. It is a highly integrated electromechanical system with multiple sensing functions and intelligence. Reliable grasping, good environmental adaptability, simple control, strong adaptability, and high autonomy are important symbols to measure the level of robot gripper design. Chinese invention patent CN 205219142U discloses a...

Problems solved by technology

The robot gripper with this structure is equipped with an opening and closing gripper assembly and a self-adjusting gripper assembly with an adjustable shape, but this device must use compressed air to drive the cylinder to move, and it cannot be used normally in a factory without compressed air supply. And this device is inconvenient to adjust the claw, thereby limiting its scope of application
