Method for making backlight module frame

Abstract

An exemplary method for making a backlight module frame includes: providing a pair of metallic strips that are spaced apart, and a plurality of elongated metallic sheets; continuously welding the elongated metallic sheets to connect with the pair of the metallic strips one by one to form a plurality of connected semi-manufactured frames corresponding to the subsequent backlight module frame; and pressing the connected semi-manufactured frames one by one to form a plurality of backlight module frames continuously. It is convenient for the backlight module frames to be mass-produced.

1 . A method for making backlight module frames continuously, the method comprising:
 providing a pair of metallic strips that are spaced apart, and a plurality of elongated metallic sheets;   continuously welding the elongated metallic sheets to connect with the pair of the metallic strips one by one to form a plurality of connected semi-manufactured frames corresponding to the subsequent backlight module frame, the longitudinal ends of each metallic sheet being welded with one of the metallic strips respectively; and   pressing the connected semi-manufactured frames one by one to form a plurality of backlight module frames continuously.   
   
   
       2 . The method of  claim 1 , wherein the pair of metallic strips is fed to a welding apparatus in an automatic feeding mechanism for welding with the elongated metallic sheets. 
   
   
       3 . The method of in  claim 1 , wherein each of the metallic strips is coiled. 
   
   
       4 . The method of  claim 1 , wherein the width of each of the elongated metallic sheets is configured to be larger than or equal to twice as wide as that of the backlight module frame. 
   
   
       5 . The method of  claim 1 , wherein the width of each of the metallic strips is configured to be larger than or equal to that of the backlight module frame. 
   
   
       6 . The method of  claim 1 , wherein ends of the elongated metallic sheets and the metallic strips are polished before the welding process. 
   
   
       7 . The method of  claim 1 , wherein the welding step uses a laser selected from the group consisting of a CO 2  gas laser and an Nd: YAG solid-state laser. 
   
   
       8 . A method for making backlight module frames continuously, the method comprising:
 providing a pair of metallic strips which are spaced apart in an automatic feeding mechanism;   continuously welding a plurality of elongated metallic sheets to connect with the pair of the spaced metallic strips one by one to form a plurality of connected semi-manufactured frames corresponding to the subsequent backlight module frame, the longitudinal ends of each metallic sheet being welded with one of the metallic strips respectively, wherein distances between the adjacent elongated metallic sheets are constant;   feeding the connected semi-manufactured frames to a punching machine in an automatic feeding mechanism; and   pressing the connected semi-manufactured frames by the punching device one by one to form a plurality of backlight module frames continuously.   
   
   
       9 . The method of in  claim 8 , wherein each of the metallic strips is coiled. 
   
   
       10 . The method of  claim 8 , wherein the width of each of the elongated metallic sheets is configured to be larger than or equal to twice as wide as that of the backlight module frame. 
   
   
       11 . The method of  claim 8 , wherein the width of each of the metallic strips is configured to be larger than or equal to that of the backlight module frame. 
   
   
       12 . The method of  claim 8 , wherein ends of the elongated metallic sheets and the metallic strips are polished before the welding process. 
   
   
       13 . The method of  claim 8 , wherein the welding step uses a laser selected from the group consisting of a CO 2  gas laser and an Nd: YAG solid-state laser.
