Positioning detection method of hot-formed workpieces in ultra-high-strength steel hot stamping production line

Abstract

The invention discloses a positioning detection method for hot-formed workpieces in an ultra-high-strength rigid hot stamping production line, comprising the following steps: generating a positioning template, storing image edge information as an inspection template; positioning during production, and heating raw materials to 900°C in a heating furnace After placing it into the mold with the robot hand, the industrial computer generates the relevant content of the positioning template according to step A to find the image edge information placed this time, compares it with the image edge information of the inspection template of the same product, and gives the matching rate; the industrial computer passes The communication module sends the matching rate information to the PLC; the invention automatically judges whether the heated raw material is placed in the exact position in the mold through machine vision, which can reduce labor intensity, improve production efficiency, and ensure that all raw materials are placed Correct, to ensure the qualified rate of products, avoid losses caused by mold damage, and improve economic benefits.

Description

Technical field [0001] The present invention relates to the field of automotive parts thermoforming technology, particularly to a super high strength rigid hot stamping production line in the thermoforming workpiece positioning detection method. Background [0002] The automobile industry is a pillar industry of national economic development, with a strong degree of industrial relevance, and is regarded as an important symbol of a country's economic development level. The stamping process is the top priority of the four major processes of the automobile, and it is also the first of the four major processes. According to incomplete statistics, more than 40% of the car parts are stamped parts of metal plates. Among them, the ultra-high strength steel hot stamping technology can produce parts with tensile strength of up to 1500MPa, which has the dual advantages of achieving automobile lightweight and improving safety. The demand for hot stamped parts maintains a rapid upward trend, ...
