System and method for quickly teaching line heating intelligent robots

Abstract

The invention provides a system for quickly teaching line heating intelligent robots. The system comprises a framework assembly, a head assembly and a control device. The head assembly is provided with a fire lance and a laser measuring device; teaching data information inputted by users and preset distance ranges from the fire lance to machined steel plates can be acquired by an upper computer in man-machine interaction modes, and the teaching data information can be transmitted to a multi-axis movement execution unit; the framework assembly and the head assembly can run in a linkage manner under the control of the multi-axis movement execution unit according to the acquired teaching data information, and the spatial location of the framework assembly and attitudes of the fire lance of the head assembly can be controlled, so that line heat forming can be carried out on the steel plates. The system has the advantages that experience of plate burning workers can be quickly and directly effectively taught to the robot to the greatest extent, accordingly, plate burning effects realized by the line heating intelligent robots can reach the level of plate burning effects realized by the skilled workers, the line heating intelligent robots can be stably and efficiently put into production, and the system is simple and is easy to use and low in development cost.

Description

technical field [0001] The invention relates to the field of water-fired board processing in the shipbuilding industry, in particular to a rapid teaching system and method for a water-fired bending board intelligent robot. Background technique [0002] Water and fire bending (line heating or line heat forming) is a forming process that utilizes the local thermoelastoplastic deformation of the metal plate after being partially cooled by high temperature to achieve overall bending. It is widely used in the processing and forming of hull plates. [0003] The water-fired board processing technology has long relied on the manual operation of workers based on experience, and there are problems such as strong dependence on experience, low processing efficiency, and difficult to guarantee processing quality. [0004] Nowadays, the competition in the ship market is becoming increasingly fierce. All countries have started the research and development of CNC water-fired plate bending ...

AI Technical Summary

Problems solved by technology

A steel plate has 20 fire paths, which takes more than 2 hours in total, which affects the actual work efficiency

Moreover, the steel plate will be deformed during the processing, and the deformation will lead to the deviation of the movement track taught at the beginning.

[0006] There are two existing processing methods for hull panels: one is manual operation that relies entirely on workers’ experience, which has problems such as strong dependence on experience, low processing efficiency, and difficulty in guaranteeing processing quality.

The other is to develop a water-fire bending intelligent robot with an expert system to realize automatic processing, but the existing water-fire bending expert system is not perfect, and the calculated data will be incorrect or unreasonable, such as the processing fire path exceeds Outside the board, there are redundant or insufficient processing fire circuits, and the sequence of processing fire circuits is unreasonable, and the development cost of the expert system is relatively high
