High-precision numerical control system for four-roll veneer reeling machine based on machine vision

Abstract

The invention discloses a high-precision numerical control system for a four-roll veneer reeling machine based on machine vision. The system comprises four pairs of veneer-reeling deformation monitoring devices which respectively connected with one side of an upper roll, a lower roll, a left roll and a right roll, wherein each pair of veneer-reeling deformation monitoring devices include a veneer-reeling pressure sensor, an angle displacement sensor and a CDD camera; the four CDD cameras are respectively connected with an image processing module and an industrial personal computer through image collecting modules; the industrial personal computer is also connected with a display module, a sound-light alarm module, a communication module, an upper roll servo device, a lower roll servo device, a left roll servo device, a right roll servo device and a veneer-reeling winding track module. The high-precision numerical control system disclosed by the invention can guarantee higher precision of the reeled products; the data are stored in the industrial personal computer, can be called at real time and can be used by the product check personnel; the check efficiency of the products is increased; the check effect is excellent.

Description

technical field [0001] The invention relates to the technical field of a four-roller plate bending machine, in particular to a high-precision numerical control system of a four-roller plate bending machine based on machine vision. Background technique [0002] The traditional four-roller plate rolling machine relies on human eyes to judge the completion, the error is relatively large, and multiple plate rolling is required, which is labor-intensive and time-consuming. Therefore, machine vision is introduced into it, which can improve the precision of the plate rolling, and can also increase the speed of the plate rolling. On this basis, this patent proposes a vision-type four-roll plate rolling machine numerical control, which combines the vision system control and the four-roll plate rolling machine numerical control system control together, thereby facilitating the realization of fully automatic plate rolling. [0003] The application number is CN201110313326.6, and the n...

Problems solved by technology

[0004] However, when the visual numerical control system is in use, although it accurately monitors the power output system of the upper, lower, left, and right rollers, it does not accurately monitor the coiling condition of the coiling machine, resulting in defects or defects in the coiling machine. Faults, the CNC system will not be found in time, still need manual monitoring and processing, the defective rate is high, and manual inspection is required in the later stage, and the production efficiency is low
