Back cover manufacturing method

Abstract

A back cover manufacturing method includes providing a striped sheet, bending the striped sheet along a long side of the striped sheet to form a hem, cutting the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly forming a plurality of striped sections, and bending the plurality of striped sections to form a back cover. The back cover is used for being disposed in a backlight module to hold at least one optical component of the backlight module.

What is claimed is: 
     
         1 . A back cover manufacturing method comprising:
 providing a striped sheet;   bending the striped sheet along a long side of the striped sheet to form a hem;   cutting the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly forming a plurality of striped sections; and   bending the plurality of striped sections to form a back cover;   wherein the back cover is used for being disposed in a backlight module to hold at least one optical component of the backlight module.   
     
     
         2 . The back cover manufacturing method of  claim 1 , wherein cutting the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly forming the plurality of striped sections comprises:
 utilizing a punching process to cut the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly from the plurality of striped sections.   
     
     
         3 . The back cover manufacturing method of  claim 1 , wherein bending the plurality of striped sections to form the back cover comprises:
 utilizing a punching process to bend the plurality of striped sections to form the back cover.   
     
     
         4 . The back cover manufacturing method of  claim 1  further comprising:
 utilizing a connecting member to connecting to two ends of the back cover. 
 
     
     
         5 . The back cover manufacturing method of  claim 1 , wherein cutting the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly forming the plurality of striped sections comprises cutting the striped sheet to make the striped sheet have four concave portions for correspondingly forming five striped sections, and bending the plurality of striped sections to form the back cover comprises bending the five striped sections to make adjacent striped sections perpendicular to each other for forming the back cover in a rectangular shape. 
     
     
         6 . The back cover manufacturing method of  claim 1 , wherein cutting the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly forming the plurality of striped sections comprises cutting the striped sheet to make the striped sheet have three concave portions for correspondingly forming four striped sections, and bending the plurality of striped sections to form the back cover comprises bending the four striped sections to make adjacent striped sections perpendicular to each other for forming the back cover in a rectangular shape. 
     
     
         7 . The back cover manufacturing method of  claim 1 , wherein cutting the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly forming the plurality of striped sections comprises cutting the striped sheet to make the striped sheet have two concave portions for correspondingly forming three striped sections, and bending the plurality of striped sections to form the back cover comprises bending the three striped sections to make adjacent striped sections perpendicular to each other for forming the back cover in a U shape. 
     
     
         8 . The back cover manufacturing method of  claim 1 , wherein cutting the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly forming the plurality of striped sections comprises cutting the striped sheet to make the striped sheet have one concave portion for correspondingly forming two striped sections, and bending the plurality of striped sections to form the back cover comprises bending the two striped sections to make the two striped sections perpendicular to each other for forming the back cover in an L shape. 
     
     
         9 . The back cover manufacturing method of  claim 1 , wherein the striped sheet is made of steel material or aluminum material.
