Description

Technical Field

[0001] The utility model relates to the technical field of the grinding process of optical fiber connectors, and particularly relates to an automatic grinding device. Background Art

[0002] As is well known, optical fibers are currently widely used, especially for communication, signal transmission, or optoelectronic transmission. The optical fiber connectors (i.e., both ends of the optical fiber) must be processed into a slightly convex surface so that the optical loss between the two optical fibers is minimized when they are joined.

[0003] Therefore, to meet the requirements of high transmission quality and low defect rate of optical fibers, the control of the pressure and time during the grinding of the optical fiber connectors by the grinding machine needs to be very precise. The required pressure is calculated based on data obtained from different grinding processes, grinding discs, and time. This data is provided by the manufacturer for use in the grinding processing factory after testing. The traditional grinding machine adjusts the required pressure by using weights for counterweight. When grinding the optical fiber connectors, according to the data provided by the manufacturer, the downward gravity of the weights is adjusted to generate a predetermined grinding pressure between the optical fiber connectors and the grinding disc on the grinding table for grinding.

[0004] However, the traditional grinding machine adjusts the grinding pressure by using weights, and this method of adjusting the grinding pressure is too crude and inaccurate. In addition, the fixture for fixing the optical fiber connectors is set on the grinding machine, and it is easy to be hindered and inconvenient when inserting and removing the optical fiber connectors from the fixture. Therefore, how to improve the accuracy and convenience of the grinding machine when adjusting the grinding pressure has become an issue to be improved.

[0005] In view of the above problems, Patent No.: 201310436083.4 discloses an optical fiber ferrule grinding device, which includes a jig, more than one optical fiber ferrule, a grinding table and a pneumatic driver. The jig is suspended on a base to restrict its rotation. A central anvil part is formed on the disk surface of the jig, and a plurality of insertion holes are distributed around the central anvil part. The optical fiber ferrule is inserted into the insertion hole through an insertion seat, and the optical fiber ferrule protrudes from the bottom of the jig. The grinding table carries a grinding sheet in a manner deviating from the rotation center, and the grinding sheet rotates eccentrically on a surface area driven by a rotator. The pneumatic driver is driven and controlled by a pneumatic-electric proportional control valve to press the central anvil part, so that the optical fiber ferrule is suspended in the surface area to receive the rotary grinding of the grinding sheet. In this way, the problems of the traditional grinding machine being difficult to control the precision of the grinding pressure and lacking convenience are improved. However, the grinding device still has the following problems: 1. It has no cleaning function. Generally, the grinding sheet needs to be replaced with a new one after being used 3-5 times. However, it is often not cleaned after the first grinding, and impurities adhere to the grinding sheet, affecting the subsequent grinding precision and efficiency. The existing method is to replace the grinding sheet after each grinding, and then clean it uniformly and continue to use. This method increases the labor intensity of workers and has a poor cleaning effect, affecting the subsequent grinding efficiency and quality. 2. The grinding sheet placement brackets of the existing grinding devices are mostly of fixed sizes and cannot be adjusted according to the size of the grinding sheet, affecting the subsequent fixture positioning and clamping actions, which may cause deviation and affect the grinding quality of the subsequent grinding sheet.
