- The present invention relates to a polishing apparatus, and more particularly, to a polishing apparatus for polishing fiber optic ferrule assemblies.
- Known fiber optic ferrule assemblies generally comprise a ferrule and an optical fiber inserted into an internal hole of the ferrule. The optical fiber can be fixed within the internal hole of the ferrule by adhesive. After fixing the optical fiber within the internal hole of the ferrule, a front end surface of the whole fiber optic ferrule assembly must be ground and polished precisely so as to achieve predetermined optical performance.
- In the prior art, to polish the front end surface of the fiber optic ferrule assembly, a plurality of fiber optic ferrule assemblies are clamped and fixed on a carrier. Then, a pressing mechanism presses a pressing head so as to press the carrier against a positioning component. The carrier is generally formed as circle-shaped or square-shaped, and the pressing head presses the carrier at a central portion thereof. However, pressing centrally is only adapted to a circle-shaped or square-shaped carrier, but not a rectangle-shaped carrier. As compared to the circle-shaped or square-shaped carrier, a rectangle-shaped carrier may carry much more fiber optic ferrule assemblies at once so as to improve the efficiency of polishing.
- When the end surface of the fiber optic ferrule assembly is ground by a polishing mechanism, the posture of the carrier will change slightly. However, in prior art, the pressing head generally has a flat bottom and thus is not adapted to the change of posture of the carrier, such that the pressing force applied on the carrier is not always perpendicular to the surface of the carrier, thereby affecting the polish accuracy of the fiber optic ferrule assembly. Furthermore, in prior art, the pressing mechanism is not provided with an elastic buffer. Thus, when the carrier is pressed, it is possible that the pressing force exerted on the carrier is suddenly increased from zero to a predetermined value, which will impact the carrier and affect the polish accuracy of the fiber optic ferrule assembly.
- A polishing apparatus according to the invention has a base, a carrier, an elevating mechanism, a pressing mechanism, and a polishing mechanism. The carrier has a plurality of work pieces disposed thereon. The elevating mechanism is mounted on the base and has a pair of positioning plates. The carrier is disposed on the pair of positioning plates. The pressing mechanism is mounted on the base and has a pair of pressing heads each including an arc-shaped protrusion respectively pressing each of a pair of opposite ends of the carrier against the pair of positioning plates. The polishing mechanism is mounted on the base and polishes the plurality of work pieces.
