Visual inspection method suitable for filament drift and impurity drift

Abstract

The invention provides a visual inspection method suitable for filament drift and impurity drift. The method comprises the following steps of S1, controlling an optical imaging device to align at theconvergence position of a to-be-formed filament bundle on any working machine table for optical imaging; S2, uploading an imaging result of the optical imaging and the machine table information of a certain working machine table to a calculation part, enabling the calculation part to carry out filament and impurity drift detection on the imaging result of the certain working machine table, and obtaining a detection result; S3, judging whether the filament drift warning information or impurity drift warning information of a processed product needs to be sent out or not according to the detection result; and S4, adjusting and processing the filament bundle on the workbench by the field staff according to the filament drift alarm information or the impurity drift alarm information. Accordingto the method provided by the embodiment of the invention, the automation degree of the filament and impurity drift detection can be effectively improved, the inspection is more accurate and timely, the inspection can be continued after a problem is found, the normal operation of the subsequent inspection work is not influenced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of intelligent monitoring of production lines in workshops, and more specifically, a visual inspection method suitable for floating threads. Background technique [0002] The silk weaving workshop of the chemical fiber factory needs to weave multiple strands of chemical fiber that are thinner than human hair into a thicker rope, using the ring blown weaving technique. During this process, the filaments twitch very fast, so there are filaments broken The problem is called floating yarn, the broken tow is mistakenly inhaled by the adjacent tow, forming a situation where there are few yarns on one side and more yarns on the other side, which is called floating yarn. At present, once the phenomenon of floating wire or floating miscellaneous occurs, the wire can only be reconnected manually. There are hundreds or more machines running automatically in a workshop. Generally, manual inspections are performed. If there are f...

Problems solved by technology

[0005] The above means can replace manual detection, but this technical means can only detect the silk thread synthesized by 72 tows. If there are 144 silk threads in the process of synthesizing silk threads, due to the large number of tows, the tows are irradiated by strip laser beams. The bright spots generated after the unit will be stacked and overlapped, which will lead to the inconsistency between the number of bright spots after collection and the number of preset threads, resulting in inaccurate detection results. In the actual process, the false positives caused by this existing technology are extremely high
