Automatic part measuring assembly system and method based on machine vision

Abstract

The invention discloses an automatic part measuring assembly system and method based on machine vision. The automatic part measuring assembly system is characterized in that the signal input end of animage processing module is connected with the signal output end of a camera, the camera is obliquely fixed to the upper part of a clamp, and a light source is in communication with a light source control module; and the light source control module and the image processing module are both in communication with a master control platform, a clamping head is fixed to the end of a clamping head sliding block, a pneumatic screw driver is fixed to the end of a screw driver sliding block, and the clamp is fixed to the upper part of a rotary assembly table. The automatic part measuring assembly methodcomprises the steps that edge information and image particles of assembly basic parts and assembly parts are obtained; the clamping head puts down the assembly parts, and the parts are placed; the master control platform drives the screw driver sliding block to move to a screw hole according to the edge information and the screw hole position; and screws adsorbed at the bottom of the pneumatic screw driver are screwed into the screw hole by the pneumatic screw driver, and part assembly is completed. The automatic part measuring assembly system and method based on machine vision has the advantages of high assembly efficiency and good accuracy.

Description

technical field [0001] The invention belongs to the technical field of parts assembly, and in particular relates to a machine vision-based automatic parts measurement and assembly system and method. Background technique [0002] Human beings perceive the external world mainly through sensory organs such as vision, touch, hearing and smell, and vision is the most important sensory function of human beings. According to statistics, more than the external information perceived by people is obtained by vision. To put it simply, machine vision can be understood as adding a visual device to the machine, so that the machine has the function of "vision", and replaces the human eye in some fields for measurement and judgment, so that it can recognize and understand the observed things , which can determine the position of the target within the range it sees. Machine vision is not only an extension of the human eye, but also has some functions of the human brain. The purpose is to i...

Problems solved by technology

[0003] The existing parts assembly technology is mainly assembled manually, and the assembly efficiency is low. On the parts assembly line, a large number of operators will be used, which increases the production cost of the enterprise.
