Multi-assembly station operation safety system based on force perception and implementation method thereof

Abstract

The invention relates to the field of automatic production and assembly, and particularly relates to a multi-assembly station operation safety system based on force perception and an implementation method thereof. The multi-assembly station operation safety system comprises a main controller, a rotary table, a rotary table servo driver, a fence system, a transfer robot and a functional robot, wherein a rotary table motor, the rotary table, the transfer robot and the functional robot are all arranged in a fence area; the main controller is connected with the servo driver, the transfer robot andthe functional robot through a field bus; the transfer robot and the functional robot are arranged on the two sides of the rotary table, are provided with corresponding robot controllers respectivelyand are connected with the main controller through a hard wire safety link; and an one-dimensional force sensor is arranged at the clamp end of the transfer robot and connected with the robot controllers. The multi-assembly station operation safety system has the advantages that the real-time performance and stability of communication between devices are guaranteed, real-time position and state signal control and monitoring in the operation process of station main transmission devices are achieved, and accurate production positioning and workpiece transmission positioning are completed.

Description

technical field [0001] The invention relates to the field of automatic production and assembly, in particular to a force-sensing-based multi-assembly station operation safety system and an implementation method thereof. Background technique [0002] In a modern automated production workshop, the main production line includes multiple stations, and each station performs assembly and production work according to its own tasks. The production process of individual stations is more complicated, and there are situations where humans and robots or other automated equipment work at the same time. Taking automobile welding production as an example, dozens of parts need to be accurately placed on the frame and welded one by one by the robot. After completion, the parts are transferred by the conveyor line or moved to the next station by the robot. Some of the stations need to be manually loaded in order, and several robots perform welding and overall handling work one by one. Due t...

Problems solved by technology

Due to the unavoidable safety hazards in the collaborative work between humans and automation equipment, and when humans misuse the workpiece, it is easy to cause the workpiece to deform due to the slight interference between the tooling and the workpiece held by the robot during the process of the robot grabbing and placing the workpiece from the fixed tooling. and damage, which causes hidden dangers to production safety and affects the production rhythm when the accident occurs, and also increases the workload for the quality inspection of later products
