Working method for safe man-robot cooperation assembly robot

Abstract

The invention discloses a working method for a safe man-robot cooperation assembly robot and relates to the technical field of intelligent manufacturing. Firstly, a worker set working parameters and instructions through a controller and a touch screen, and a first joint arm and a second joint arm conduct rotational adjustment in the horizontal direction under driving of an alternating current torque electromotor; under driving of a hollow shaft motor inside a connecting sleeve, a screw rod conducts vertical adjustment movement, meanwhile, a vacuum suction nozzle is started to suck air, and a screw is sucked into a locking claw head by a material supplying device through a feeding pipeline and positioned by the vacuum suction nozzle; when moving to a corresponding screw hole position, the screw rod is driven by an electric screwdriver to press rotationally, and the screw is driven by the screw rod to be continuously screwed in the hole position till totally locked in a screw hole; and after the screw is locked, the screw rod moves up to leave the screw hole position. According to the working method, safety and stability are good, highly difficult and fine actions are achieved, programming is easy, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a working method of a safe human-machine collaborative assembly robot. Background technique [0002] In recent years, with the acceleration of modernization, the demand for electrical products and home appliances has been increasing, and the mechanized and automated production and assembly lines have increased greatly. The method is far from being able to adapt to the needs of mechanization and automation mass production and assembly. Therefore, how to solve the problem of high-speed screw locking and improve the quality and consistency of locking has become a subject of great concern to those skilled in the art. [0003] In order to solve this problem, many manufacturers have developed a variety of assembly robots, the main feature of which is that there is a screw supply device to blow the screws into a left and right openable elastic jaws under the head of t...

AI Technical Summary

Problems solved by technology

[0005] 1. For safety reasons, safety protection and isolation must be installed when the robot is working, and the operator cannot approach it, and man-machine cooperation cannot be carried out;

[0006] 2. The programming is complex, time-consuming, and has high professional requirements for operators. It has poor versatility and cannot be applied on a large scale;

[0007] 3. Interference problems are prone to occur when the screw is locked, and the working stability is poor. At the same time, the positioning accuracy of each joint arm is low, which reduces the work efficiency
