Universal robot grabbing device based on electromagnetic attraction

Abstract

The invention belongs to the field of robots, and particularly relates to a universal robot grabbing device based on electromagnetic attraction. The device comprises a base, a first force arm is mounted at the top of the base, a second force arm is mounted at the output end of the first force arm, and a suspension table is mounted at the output end of the second force arm; a grabbing device body for grabbing workpieces is installed at the bottom of the suspension table and comprises a suspension frame, a base seat, an air cylinder, a piston rod, a gripper frame and grippers, the suspension frame is installed at the bottom of the suspension table, the base seat is installed at the bottom of the suspension frame, the air cylinder is installed on the base seat, the output end of the air cylinder is connected with the piston rod, the gripper frame is mounted at the other end of the piston rod, and the grippers are mounted on the gripper frame; and due to the design that the interval between the grippers is adjustable, the grippers can be adapted to gripping of the workpieces in the stroke of the piston rod at the output end of the air cylinder, the applicability of the grabbing devicebody is improved, and the tedious operation of disassembling and assembling the grippers with different intervals is omitted.

Description

technical field [0001] The invention relates to the field of robots, in particular to a general-purpose robot grabbing device based on electromagnetic adsorption. Background technique [0002] The manipulator is the earliest industrial robot and the first modern robot. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, it is widely used in machinery manufacturing, metallurgy, In the departments of electronics, light industry and atomic energy, the manipulator is an automatic operation device that can imitate certain movement functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. [0003] There are following problems in prior art: [0004] 1. When the robot grabbing device is in use, it can only grab workpieces of a fixed size. When the workpiece is replaced, the grabbing device needs to be modified...

AI Technical Summary

Problems solved by technology

[0004] 1. When the robot grabbing device is in use, it can only grab workpieces of a fixed size. When the workpiece is replaced, the grabbing device needs to be modified, resulting in limitations in the use of the robot grabbing device;

[0005] 2. When the robot grabbing device grabs the workpiece, the gripping force of the workpiece is at the contact point between the gripper and the workpiece. During the process of moving after grabbing, the workpiece falls off due to the influence of gravity, which affects the gripping of the workpiece transport stability
