Description

Optical fiber pulling and cladding equipment Technical Field The utility model relates to the technical field of endoscope processing equipment, in particular to optical fiber pulling and pressing equipment. Background ‌ Optical endoscope ‌ is a detection instrument that combines a variety of techniques including optical, ergonomic, precision mechanical, modern electronics, mathematics, and software. It is passed through an elongated tubular device into the interior of the human body or object for observation and diagnosis. At present, in the process of assembling an endoscope, a gasket is usually inserted between an optical fiber and an outer tube by manual work, and then the optical fiber is attached to the gasket by pulling the optical fiber, so that the endoscope is assembled. However, in the process of attaching the optical fiber and the gasket, glue needs to be coated on the surface of the gasket, and the friction force on the surface of the gasket is reduced due to the glue, so that the optical fiber is easy to squeeze and float up in the attaching process, the shape and the area of the optical fiber on the end face cannot be guaranteed, and further the uneven distribution of the optical fiber on the end face of the endoscope is caused, and the situation that the optical fiber end face is irregular due to the floating up of the gasket is caused, so that when the endoscope is used, the uniformity of light is poor, images with uneven brightness are generated, and the problems of misdiagnosis and missed diagnosis are caused.
