Safe cooperation robot for assembly

Abstract

The invention discloses a safe cooperation robot for assembly and relates to the technical field of intelligent manufacturing. A first joint arm is mounted on a base; a second joint arm is mounted on the first joint arm; the first joint arm and the second joint arm are both driven by an alternating current torque electromotor; an electric screwdriver and a connecting sleeve are both mounted on the second joint arm; the upper portion and the lower portion of a screw rod arranged inside the connecting sleeve are connected with the electric screwdriver and a locking claw head in a matched mode correspondingly; the screw rod is driven by a hollow shaft motor connected with the screw rod; a vacuum suction nozzle arranged at the bottom of the locking claw head is connected to a material supplying device through a feeding pipeline; a sonar sensor and a touch screen are connected to the upper portion of the base; and the base is connected with an external controller. The safe cooperation robot is good in safety and stability, intelligence of human beings and efficiency of machines are combined, highly difficult and fine actions are achieved, programming is easy, universality is good, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a safety collaborative robot for assembly. Background technique [0002] In recent years, with the acceleration of the pace of modernization, the demand for electrical products and home appliances has continued to rise, and the mechanized and automated production and assembly lines have increased significantly. The method is far from being able to meet the needs of mechanized and automated mass production and assembly. Therefore, how to solve the problems of high-speed locking screws and improve the quality and consistency of locking has become a topic 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 clamping nozzle under the screwdriver he...

AI Technical Summary

Problems solved by technology

[0005] 1. For safety reasons, safety protection and isolation must be installed, and operators cannot approach, and human-machine cooperation cannot be carried out;

[0006] 2. The overall volume of the robot is large and heavy, and it cannot move flexibly in the workshop, and the production and operation costs are high;

[0007] 3. The programming is complicated, time-consuming, and has high professional requirements for operators. It has poor versatility and cannot be applied on a large scale;

[0008] 4. The interference problem is easy 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 working efficiency
