Description

[0002] At present, there are two main types of grinders used for processing the spherical end faces of fiber optic connector plugs in my country. One is the solution of using Japan Seiko grinders. The worktable is a planetary rotary motion mode and uses a single-disc fixture. The grinder has a simple structure and is easy to use, occupying the vast majority of the market. However, in order to ensure that the grinding speed of the workpieces on the grinder fixture is the same, the workpieces are distributed in a circle. The number of optical fibers that can be processed at one time is limited, usually 12 or 24. The ordinary center machine grinding fixture is mostly equipped with 12 heads. From degumming, rough grinding, fine grinding, to polishing, it is all completed by the plate loading personnel, and the offline time is much longer than the online time. Generally speaking, when grinding 2.5 ferrule products, the manual time for loading a plate is about 90 seconds, and when grinding 1.25 ferrule products, the manual time is about 70 seconds, which restricts the production efficiency of fiber optic connector plug end face processing. In addition, because the processing trajectory is a circular spiral line, a large area of ​​the grinding disc cannot be effectively used, and the tool utilization rate is limited.
