Automatic feeding and discharging method and system on assembly line based on machine vision

Abstract

The invention discloses an automatic feeding and discharging method and system on an assembly line based on machine vision. The method comprises the steps that to-be-machined materials are sequentially placed on the assembly line, and the placing angle range of the to-be-machined materials on the assembly line is range1; a CCD camera shoots the assembly line, the current positions and the angle range1 of the to-be-machined materials on the assembly line are obtained, whether vacant positions for containing the materials exist on the assembly line or not is obtained, and the information is sentto a mechanical arm; the mechanical arm obtains the information, the positions of the to-be-machined materials during material taking are calculated, material taking is carried out, and the materialsare placed on a machining machine table; and the vacant position during discharging is calculated, the mechanical arm clamps the machined materials from the machining machine table, and after the machined materials are rotated to the angle range2, discharging is carried out on the current vacant positions. According to the technical scheme, one set of machine vision and mechanical arm is achieved, and simultaneous feeding and discharging work on the same assembly line is achieved.

Description

technical field [0001] The invention relates to the technical field of automatic loading and unloading, in particular to an automatic loading and unloading method and system on an assembly line based on machine vision. Background technique [0002] With the development of machine vision and automation technology, many automated production lines have used CCD machine vision to automatically identify and locate materials, and cooperate with manipulators to automatically load or unload materials. This method of loading and unloading has high repeat positioning accuracy. High reliability, flexible production, and high degree of automation can significantly reduce labor costs compared with manual labor, greatly improve production efficiency and ensure stable and reliable production quality. [0003] However, the current automatic loading and unloading machine based on machine vision usually needs to be separated into two parts, one part is used as an automatic loading machine and...

Problems solved by technology

[0003] However, the current automatic loading and unloading machine based on machine vision usually needs to be separated into two parts, one part is used as an automatic loading machine and the other part is used as an automatic unloading machine, which requires different manipulators, supporting mechanisms and conveyor belts, and cannot be passed through a set of machines. Vision and manipulator, on the same assembly line, do the mixed use of automatic loading + unloading at the same time

This leads to duplication of mechanisms and low utilization of site space, high cost, long production process and low efficiency
