Description

Technical field: [0001] The invention relates to a wire drawing technology, in particular to a wire drawing system and a wire drawing method for drawing high-precision monofilaments and multifilaments. Background technique: [0002] The drawing accuracy of monofilament and multifilament directly affects the spatial resolution of MCP, so using MCP optical fiber drawing machine to draw monofilament and multifilament is the core process of MCP process. MCP optical fiber drawing machine is composed of feeding system, temperature control system, drawing system, cutting system and other subsystems. The drawing system has the greatest influence on drawing precision. [0003] The existing wire drawing system controls a single servo driver through a single-chip microcomputer chip, and controls a single servo motor to drive the wire drawing assembly for wire drawing. Using a single motor to drive the driving wheel, and then drive the driven wheel to rotate together through the transm...

AI Technical Summary

Problems solved by technology

Using a single motor to drive the driving wheel, and then drive the driven wheel to rotate together through the transmission belt, this synchronous linkage control method, due to frictional resistance, and the uneven bite of the conveyor belt and the teeth of the driving wheel, the speed of the driven wheel and the driving wheel are not completely equal, which increases The ellipticity of the drawn optical fiber makes the cross-section of the optical fiber deformed and the edges rough; and when the single-chip microcomputer chip is used to control the servo driver, the single-chip microcomputer itself is susceptible to interference, especially in the drawing workshop with many high-power electrical equipment such as motors, electromagnetic The interference is greater, which greatly affects the effect of the single-chip microcomputer controlling the servo drive and reduces the drawing accuracy

It can be seen from the above that it is difficult for the existing wire drawing system to guarantee the wire drawing accuracy when drawing high-precision monofilament and multifilament

Production experience also shows that the existing wire drawing system can still ensure that the fiber diameter error is within ±4μm when drawing monofilaments and multifilaments with a diameter of 0.95mm or more. The diameter error can only be guaranteed within ±5μm
