A workpiece stamping system and its control method based on machine vision

Abstract

The invention discloses a workpiece stamping system based on machine vision. Signals are output from an industrial control computer to a robot, and the tail end of the robot is provided with an electric sucker used for sucking a blank; a blank arranging position, a detection position and a stamping die position are arranged in the working range of the robot, and an industrial camera and an eddy current sensor are installed at the detection position; and collected signals are output from the industrial camera and the eddy current sensor to the industrial control computer. According to the workpiece stamping system based on machine vision, recognition of round holes can be performed effectively and quickly, and pose correction can be quickly performed on a system platform according to a vision location algorithm; and a workpiece is placed on a stamping die accurately, and the accurate stamping position is ensured.

Description

technical field [0001] The invention relates to the field of automatic stamping. Background technique [0002] In the machinery manufacturing industry, stamping equipment is generally considered to be inferior equipment, and insufficient attention has been paid to the automation and intelligent application of the stamping production line, resulting in the low level of overall technological development of my country's stamping industry, which seriously affects the improvement of enterprise production efficiency; and stamping manufacturing The production environment of enterprises is generally harsh, the rate of safety accidents is high, and the problem of labor loss is serious. [0003] At present, there are also stamping equipment that uses a visual system for positioning. For example, the publication number is CN201210558242, and the patent name is "Stamping Equipment Based on Vision Positioning System". When loading parts, multiple pieces may be adsorbed at the same time. ...

[0002] In the machinery manufacturing industry, stamping equipment is generally considered to be inferior equipment, and insufficient attention has been paid to the automation and intelligent application of the stamping production line, resulting in the low level of overall technological development of my country's stamping industry, which seriously affects the improvement of enterprise production efficiency; and stamping manufacturing The production environment of enterprises is generally harsh, the rate of safety accidents is high, and the problem of labor loss is serious

[0003] At present, there are also stamping equipment that uses a visual system for positioning. For example, the publication number is CN201210558242, and the patent name is "Stamping Equipment Based on Vision Positioning System". When loading parts, multiple pieces may be adsorbed at the same time. In addition, during visual recognition, by measuring the distance between the photographed pattern position and the two vertical sides of the positioning, if any distance measurement is inaccurate, the calculated relative deviation data error Big cause positioning failure
