Description

TECHNICAL FIELD

[0001] The present application relates to the field of optical fiber grinding equipment, in particular to an optical fiber grinding device capable of automatically adding abrasive agent. BACKGROUND

[0002] In the field of optical fiber manufacturing and processing, the optical fiber grinding mechanism plays a crucial role. It is mainly used for high-precision grinding of the end face of the optical fiber to enable the optical fiber to meet the connection and transmission requirements in various application scenarios such as optical communication. The abrasive agent is an indispensable key element in the optical fiber grinding process, which can help improve the grinding quality and efficiency and ensure that the optical fiber end face meets the corresponding flatness and smoothness indicators.

[0003] The material of the optical fiber usually has high hardness and certain toughness. Simply relying on the friction between the grinding disc and the optical fiber for grinding, the grinding speed will be relatively slow. The abrasive agent contains abrasive components with moderate hardness and fine and uniform particles. During the grinding process, these abrasives can be embedded on the surface of the grinding disc or fully contact the optical fiber end face in the grinding area. Through the friction between the abrasive particles and the optical fiber, the removal speed of the optical fiber end face material is accelerated, thereby effectively shortening the grinding time and improving the overall grinding efficiency.

[0004] Currently, in the actual application of many optical fiber grinding mechanisms, the addition of the abrasive agent is mostly in the form of manual addition. When manually adding the abrasive agent, the operator first needs to stop the ongoing grinding work, open the corresponding addition port or protective device of the grinding machine, and then use a measuring tool to take out the appropriate amount of abrasive agent and place it in the designated position of the grinding disc. Frequent manual addition operations greatly slow down the overall production efficiency, and the subjectivity of manual operation and the inevitable errors make it difficult to ensure that the amount of abrasive agent added each time and the distribution in the grinding area are uniform and consistent, resulting in uneven addition of the abrasive agent.
