Plastic part grabbing manipulator with five degrees of freedom

Abstract

The invention provides a plastic part grabbing manipulator with five degrees of freedom. The plastic part grabbing manipulator comprises a machine body, a mechanical arm and a manipulator, wherein the mechanical arm comprises a main arm and an auxiliary arm, the main arm comprises a planar frame having a horizontal movement degree of freedom and composed of a stress plate, a retainer and a connection frame, and the auxiliary arm comprises an auxiliary arm rod, a slide block guide rail and an auxiliary arm cylinder, and has a vertical movement degree of freedom; the machine body comprises a base and a mechanical arm support frame, and a rocker mechanism is arranged on the mechanical arm support frame; and the manipulator comprises a grabbing mechanism and a wrist rotation cylinder, the wrist rotation cylinder drives a chuck to rotate relative to the mechanical arm, so that the manipulator has a second rotation degree of freedom. The plastic part grabbing manipulator with the five degrees of freedom is light in mass, high in assembly accuracy, capable of accurately grabbing plastic parts during an injection and taking process, and stable in working.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a manipulator for grasping plastic parts with five degrees of freedom. Background technique [0002] The so-called manipulator is a kind of mechanical equipment that imitates human limbs to help people or replace people to perform actions. With the rapid development of technology and manufacturing, manipulators have been used more and more, and have become a part of the manufacturing industry. an integral part. After decades of development, and rapid development, manipulator (robot) has become a discipline. It includes a variety of fields, and it can be said that it currently involves the widest range of disciplines. If a high-tech manipulator can generally involve dozens of fields such as ergonomics, engineering mechanics, material mechanics, electrical engineering, biology, etc. . The technology of the manipulator also refers to the technical level of dozens of professi...

AI Technical Summary

Problems solved by technology

Although the application of manipulators in my country has been very extensive, compared with developed countries in the world, the gap is really not one or two points. my country's research on industrial manipulators started relatively late, and there is also a big gap between China's other subsidiary technologies and foreign countries. Two points are the main factors that lead to such a big gap between the manipulators produced in our country and the manipulators of other countries.

At present, the overall mass of the mechanical arm used by the robot is heavy, and there is a disadvantage of unstable operation of the mechanical arm caused by inertia. In the process of grasping small parts, due to the irregular structure of small parts, it is difficult to accurately grasp plastic parts due to the limited freedom.
