Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to an agricultural machinery parts conveying system based on a truss robot. Background Art

[0002] The truss robot is a rectangular coordinate robot. It is a fully automatic industrial equipment based on the rectangular X, Y, Z three-coordinate system, which can adjust the workpiece position or realize the trajectory movement of the workpiece. The truss robot is mainly built with multi-dimensional robot walking axes, and each robot walking axis is composed of heavy-duty aluminum profiles, roller linear guides and servo motors. The truss robot can carry objects and operate tools to complete various operations. It has high speed, high precision, good dust and anti-fouling properties. It is designed with a complete set of material handling and storage equipment for automatic turning, drilling and other processing of bearing workpieces to meet the needs of actual machine tool production lines.

[0003] Most existing truss robots can only carry a single object or multiple objects stacked together at the same time. However, in the processing of agricultural machinery parts, the processing time of each process is not the same. When the time of the previous process is much shorter than that of the next process, one previous process will be set with multiple next processes. The truss robot is required to move the agricultural machinery parts completed in the previous process to the next process one by one. At this time, the existing truss robot has a low transportation efficiency. Summary of the invention
