Lens tray fastening device

Abstract

Provided is a lens tray fastening device being capable of fastening a plurality of different types of lens trays. Two locating pins are arranged in each of the lens trays. The lens tray fastening device includes a base. The base is separated into a number of areas. Each area defines a first locating hole and a number of second locating holes. The position of the first locating hole corresponds to that of one of the locating pins, and the position of one of the second locating holes corresponds to that of the other second pin. The first locating hole is in cooperation with one of the second locating holes to engage with the two locating pins to position each of the lens trays onto the base.

         2 . The lens tray fastening device of  claim 1 , wherein the base is substantially square, the connection lines between the first locating hole and the second locating holes are on the same diagonal line in each of the areas. 
     
     
         3 . The lens tray fastening device of  claim 1 , wherein both the first locating hole and the second locating holes are blind holes. 
     
     
         4 . The lens tray fastening device of  claim 1 , wherein the areas of the base are arranged in a 3×3 array. 
     
     
         5 . A lens tray fastening device for fastening a plurality of different types of lens trays, each of the lens trays comprising a first locating pin and a second locating pin, the lens tray fastening device comprising:
 a base, the base comprising a plurality of areas, the areas arranged in a 3×3 array, each of the areas defining a first locating hole and a plurality of second locating holes, the position of the first locating hole spatially corresponding to that of the first locating pin, one of the plurality of second locating holes spatially corresponding to that of the second locating pin, the first locating hole being cooperative with one of the second locating holes to engage with the first and second locating pins to locate each of the lens trays onto the base, the base defining a plurality of groups of threaded holes, each of the threaded holes defined on the boundary defined by two adjacent areas of the base;   a plurality different type of plates, each type of plates corresponding to a respective type of lens trays, each of the plates defining a plurality of through holes, each of the through holes corresponding to a respective one of the threaded holes, each of the plates configured for bestriding two adjacent lens trays and resting against peripheries of the two adjacent lens trays;   a plurality of bolts, each of the bolts passing through a respective one of the through holes and threadedly engaging with a respective one of the threaded holes to firmly attach each of the lens trays on the base.   
     
     
         6 . The lens tray fastening device of  claim 5 , wherein the base is substantially square, the connection lines between the first locating hole and the second locating holes are on the same diagonal line in each of the areas. 
     
     
         7 . The lens tray fastening device of  claim 5 , wherein both the first locating hole and the second locating holes are blind holes. 
     
     
         8 . The lens tray fastening device of  claim 5 , wherein each group of threaded holes comprises three threaded holes. 
     
     
         9 . The lens tray fastening device of  claim 5 , wherein the connection line of each group of threaded holes is on the same line.
