Heavy-load SCARA (selective compliance assembly robot arm) transfer robot

Abstract

The invention discloses a heavy-load SCARA (selective compliance assembly robot arm) transfer robot and belongs to the technical field of industrial robots. The robot comprises a rack, a first rotating joint, a second rotating joint and a wrist mechanism, an engine seat in the rack is fixedly connected with a big-arm steel wheel flange in the first rotating joint through bolts, a big arm in the first rotating joint is fixedly connected with a second harmonic speed reducer in the second rotating joint through bolts, and a small arm in the second rotating joint is connected with the wrist mechanism through a deep groove ball bearing and a double row angular contact ball bearing. The heavy-load SCARA transfer robot has the advantages of compact structure, easiness in machining and manufacturing, low machining cost, high load carrying capacity and relatively simple transmission.

Description

Technical field: [0001] The invention belongs to the technical field of industrial robots, and in particular relates to a large-load SCARA handling robot whose load capacity can reach 15Kg. Background technique: [0002] In the automated production lines of light industry, medicine, food and electronics industries, such as sorting, packaging and packaging, especially in repetitive, boring and dangerous tasks such as material handling and machine tool loading and unloading, in order to reduce human labor Intensity, improve work efficiency, in the operation process, it is often necessary to place repetitive work robots in space, but it is unnecessary to use multi-degree-of-freedom space parallel manipulators, or the manufacturing cost is too high, serial five-axis six-axis Robots are too expensive to manufacture. The traditional SCARA robot, in order to increase its handling speed, often reduces its load capacity. At present, there is still no domestic application of SCARA ro...

[0002] In the automated production lines of light industry, medicine, food and electronics industries, such as sorting, packaging and packaging, especially in repetitive, boring and dangerous tasks such as material handling and machine tool loading and unloading, in order to reduce human labor Intensity, improve work efficiency, in the operation process, it is often necessary to place repetitive work robots in space, but it is unnecessary to use multi-degree-of-freedom space parallel manipulators, or the manufacturing cost is too high, serial five-axis six-axis Robots are too expensive to manufacture

The traditional SCARA robot, in order to increase its handling speed, often reduces its load capacity. At present, there is still no domestic application of SCARA robots in the field of 5Kg to 15Kg handling.

However, in the design field of high-speed and high-precision SCARA robots with large loads, the wrist structure of SCARA robots is relatively thin, so that the load capacity of SCARA robots cannot meet the requirements of large loads, and the selected kinematic joints have complex structures.

At present, most industrial robots in China are large in size and heavy, resulting in high manufacturing costs, troublesome assembly, and inconvenient transportation.
