Description

Technical Field

[0001] The invention relates to the technical field of optical fiber head processing equipment, and in particular to a multi-station automatic grinding system and a grinding processing method. Background Art

[0002] After the processing of the optical fiber connector is completed, in order to make the surface of the optical fiber end flat and improve the stability of signal transmission after the optical fiber connection, it is often necessary to grind its end face. At present, when grinding, the optical fiber connector is usually fixed on a plate by multiple pressing plates, and then the position of the pressing plate is locked by screws. After completion, the plate is placed on the grinding device, and the plate is fixed by screws or fixing mechanisms, and then the grinding operation is performed. At present, when the plate is fixed, in order to ensure the stability of the plate after fixing, and the end of the optical fiber can act on the grinding plate, screw fixing is usually adopted, and generally four screws are required for fixing. When the fixing mechanism is used for fixing, the eccentric rod is generally used for rotating and pressing. This method is simple to operate, but the horizontality of the plate after fixing is poor. In view of the above problems, the publication number: CN202321837829.8 discloses a fiber head grinder, including a body, a control panel is provided on one side of the body, a mounting table is installed on the upper end of the body, a motor is installed in the body, and a grinding disc is connected to the output shaft of the motor. The grinding disc provided above can be eccentrically arranged on the motor, or it can be coaxially arranged. A cloth specially used for optical fiber grinding is also pasted on the upper wall of the grinding disc. A fixing mechanism for fixing the optical fiber head and a connecting mechanism for fixing the placement plate are also provided thereon. Compared with the prior art, the utility model is convenient for grinding the optical fiber end face on the optical fiber head, and has the effect of conveniently fixing the optical fiber head and fixing multiple optical fiber heads during grinding.

[0003] However, the above-mentioned grinder still has the following problems: 1. The automation efficiency is low, and it can only perform grinding processing, but cannot perform automatic cleaning. It needs to replace another device for cleaning, which affects the processing efficiency and cannot meet the needs of existing mass production of optical fiber heads; 2. The existing grinder requires manual transportation of the carrier and replacement of the grinding disc, which is labor-intensive and costly, and requires shutdown for operation, affecting the processing efficiency; 3. The mounting holes of existing carriers are mostly fixed in size and cannot automatically adjust the aperture. They can only be used to fix optical fiber heads of one size and have low applicability. They need to be customized and subsequently replaced, which increases costs and affects efficiency. Summary of the invention
