Image type spinneret plate automatic detector

Abstract

The invention provides an image type spinneret plate automatic detector which comprises a microscope, a CCD (Charge Coupled Device), a lighting system, an electrical control card and a personal computer, with a three-axis CNC (Computerized Numerical Control) moving worktable as a main body, wherein the three-axis worktable can be driven by the electrical control card to realize programmed control under the control of the computer. The personal computer is provided with an image acquisition card and receives a workpiece image captured by an optical imaging system which consists of the microscope and the CCD. The personal computer is internally provided with a spinneret plate automatic detection module, the spinneret plate automatic detection module can automatically plan a detection process aiming at a circular spinneret plate and a square spinneret plate and automatically control the three-axis moving worktable in the detection process, the detection positions of spinneret holes are moved to a vision center of the microscope one by one according to a generation sequence, an edge point set of the holes of the spinneret plate is automatically extracted, and whether the spinneret holes are qualified or not is judged with the image of the spinneret holes and the edge point set.

Description

technical field [0001] The invention is an instrument for fully automatic detection of spinnerets by adopting an optical image method, which can quickly and efficiently detect the spinneret holes in the spinneret and judge whether the size of the spinneret holes is qualified or not. Background technique [0002] The spinneret is a precision part on the chemical fiber spinning machine, also known as the spinning head, which has many spinneret holes of the same size. During spinning, the spinning solution or melt passes through these micropores and squeezes into the coagulation bath or air in a thin flow state, that is, solidifies or cools to become fibers. The spinneret is the most important core component in the spinning industry, which directly affects the quality of the finished silk. During the long-term working process of the spinneret, problems such as blockage and erosion of the spinneret hole will occur, and the filaments ejected from the spinneret hole with the prob...
