Definitions

  • 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.
  • 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.
  • pressing centrally is only adapted to a circle-shaped or square-shaped carrier, but not a rectangle-shaped carrier.
  • a rectangle-shaped carrier may carry much more fiber optic ferrule assemblies at once so as to improve the efficiency of polishing.
  • the posture of the carrier will change slightly.
  • 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.
  • 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 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.
  • FIG. 1 is a perspective view of a polishing apparatus according to the invention
  • FIG. 2 is a sectional view of the polishing apparatus of FIG. 1 ;
  • FIG. 3 is a sectional view of a pressing head of another polishing apparatus according to the invention.

  • the elevating mechanism 100 is mounted on the base 10 and has a pair of positioning plates 115 for installing and positioning the carrier 400 thereon.
  • the carrier 400 is constructed to carry work pieces 500 to be polished thereon.
  • the carrier 400 in the embodiment shown in FIG. 1 , has a substantial rectangle profile or any other proper profile.
  • the elevating mechanism 100 also comprises a pair of vertical support plates 110 , 120 oppositely mounted on the base 10 , a pair of vertical slide rails 111 provided on the support plates 110 , 120 , respectively, a pair of slide blocks 112 slidably mated with the vertical slide rails 111 , respectively, a connection beam 114 connecting the pair of slide blocks 112 and the pair of positioning plates 115 so as to simultaneously move the slide blocks 112 and the positioning plates 115 , and a first drive 130 mounted on one of the vertical support plates 110 , 120 so as to drive the slide blocks 112 to move up and down along the vertical slide rails 111 , respectively.
  • the slide block 112 is connected to the connection beam 114 by a connection plate 113 .
  • the vertical slide rails 111 , the slide blocks 112 and the first drive 130 are mounted on outer sides of the vertical support plates 110 , 120 , respectively.
  • the second drives 210 , 220 are mounted on inner sides of the vertical support plates 110 , 120 , respectively.
  • the first drive 130 is a linear actuator, for example, an air cylinder, a hydraulic cylinder or an electrical actuator.
  • the pressing mechanism 200 , 300 comprises a pair of second drives 210 , 220 mounted on the pair of vertical support plates 110 , 120 and driving a pair of pressing heads 310 , 320 , respectively, so as to press the pair of pressing heads 310 , 320 against the surface of the carrier 400 .
  • Horizontal pressing plates 230 are disposed on actuation ends of the second drives 210 , 220 and upper end surfaces of the pressing heads 310 , 320 are attached to the horizontal pressing plates 230 , respectively.
  • the second drives 210 , 220 each are a linear actuator, for example, an air cylinder, a hydraulic cylinder or an electrical actuator.
  • the polishing mechanism 20 as shown in FIGS. 1 and 2 , comprises a horizontal support plate disposed below the positioning plates 115 and a polishing film placed on the horizontal support plate and reciprocatingly moving along with the horizontal support plate.

  • the carrier 400 is positioned on the positioning plates 115 in the manner of pin-hole mating; each of the pair of positioning plates 115 has a positioning pin 115 a extending vertically upward, and each of both ends of the carrier 400 is formed with a positioning passageway 400 a .
  • the positioning pin 115 a of the positioning plate 115 is fitted into the respective positioning passageway 400 a of the carrier 400 .
  • Each of the positioning plates 115 has a horizontal extending portion 115 b at an end of which the positioning pin 115 a is located, and both ends of the carrier 400 are placed on the horizontal extending portions 115 b of the pair of positioning plates 115 .
  • the pressing mechanism 200 , 300 is mounted on the base 10 and the pair of pressing heads 310 , 320 press both ends of the carrier 400 against the pair of positioning plates 115 .
  • the pressing heads 310 , 320 each have an arc-shaped protrusion 310 a , 320 a , as shown in FIG. 2 , for directly contacting a surface of the carrier 400 to directly press the surface of the carrier 400 .
  • the arc-shaped protrusions 310 a , 320 a each may be formed as hemisphere-shaped or hemicylinder-shaped.
  • a plurality of positioning slots are formed in the carrier 400 and the plurality of fiber optic ferrule assemblies 500 are clamped and positioned within the plurality of positioning slots of the carrier 400 .
  • the polishing mechanism 20 is mounted on the base 10 and constructed to polish end surfaces of the fiber optic ferrule assemblies 500 mounted on the carrier 400 .
  • the polishing mechanism 20 reciprocatingly moves so as to polish the end surfaces of the fiber optic ferrule assemblies 500 .

In this way, when the pressing heads 310 , 320 are pressed downward, it will be deformed elastically gradually, such that the pressing force exerted on the carrier 400 is gradually and smoothly increased from zero to a predetermined value, rather than impact the carrier 400 .
  • the first drive 130 moves the pair of slide blocks 112 upward along with the pair of positioning plates 115 so as to raise the carrier 400 mounted on the pair of positioning plates 115 , thereby replacing the polishing film below the carrier 400 .
  • the first drive 130 moves the pair of slide blocks 112 downward along with the pair of positioning plates 115 so as to lower the carrier 400 mounted on the pair of positioning plates 115 until reach a predetermined position.
  • a pressing head 310 ′, 320 ′ of the polishing apparatus 200 , 300 according to another embodiment of the invention is shown in FIG. 3 .
