Method of rounding metal edge and eliminating taping at fatp

Abstract

A method of the subject technology includes placing a workpiece between a bending block including a tooth and a stage of a bending tool. The method further includes adjusting a position of the workpiece to place a burr of the workpiece under the tooth of the bending block and pushing the bending block against the workpiece to bend the burr to prevent damage to an adjacent non-metal part.

         1 . A method, comprising:
 placing a workpiece between a bending block including a tooth and a stage of a bending tool;   adjusting a position of the workpiece to place a burr of the workpiece under the tooth of the bending block; and   pushing the bending block against the workpiece to bend the burr to prevent damage to an adjacent non-metal part.   
     
     
         2 . The method of  claim 1 , further comprising improving bending of the burr by using a side-forging technique. 
     
     
         3 . The method of  claim 2 , further comprising performing the side-forging technique by using a forting tool including a press-down part and a sliding part. 
     
     
         4 . The method of  claim 3 , wherein pushing the press-down part causes the sliding part to press the bent burr to improve bending of the burr. 
     
     
         5 . The method of  claim 4 , wherein improving the bending of the burr is achieved by further pushing the burr toward a fixed support of the bending tool. 
     
     
         6 . The method of  claim 5 , wherein pushing the bending block against the workpiece is supported by the fixed support. 
     
     
         7 . The method of  claim 1 , wherein the burr comprises an edge of a slot in the workpiece, and wherein the adjacent non-metal part comprises a flexible printed circuit (FPC). 
     
     
         8 . The method of  claim 1 , wherein the workpiece comprises a metal plate, and wherein the metal plate is part of a virtual reality (VR) or a wearable consumer electronic device. 
     
     
         9 . The method of  claim 1 , wherein the tooth of the bending block includes a curvature having a radius that is dependent on a material and a thickness of the workpiece. 
     
     
         10 . The method of  claim 1 , wherein adjusting the position of the workpiece comprises moving the workpiece horizontally over the stage. 
     
     
         11 . A method, comprising:
 manufacturing a plurality of irregular metal pieces;   bending a corner of a plate workpiece to accommodate mounting an adjacent part; and   attaching an irregular metal piece of the plurality of irregular metal pieces at the bent corner of the plate workpiece,   wherein an irregularity of the irregular metal piece matches the bent corner.   
     
     
         12 . The method of  claim 11 , wherein the irregularity of the irregular metal piece includes a cut off portion of a side of the irregular metal piece. 
     
     
         13 . The method of  claim 11 , wherein the plurality of irregular metal pieces comprise a plurality of nuts. 
     
     
         14 . The method of  claim 11 , wherein the plate workpiece comprises a metal plate used in a VR device or a wearable device. 
     
     
         15 . The method of  claim 11 , further comprising improving the bending of the corner of the plate workpiece by using a forging technique to further push in a burr of the bent corner. 
     
     
         16 . The method of  claim 15 , wherein the adjacent part comprises an FPC and using the forging technique prevents long-term damage to the FPC. 
     
     
         17 . The method of  claim 11 , wherein bending the corner of the plate workpiece comprises using a bending tool including a bending block having a tooth with a curvature. 
     
     
         18 . The method of  claim 17 , wherein a radius of the curvature of the tooth is dependent on a thickness and material of the plate workpiece. 
     
     
         19 . An apparatus comprising:
 a bending block including a tooth having a curvature configured to move toward a workpiece; and   a stage configured to support the workpiece,   wherein:   the bending block is configured to bend a burr of a slot of the workpiece to prevent long-term damage to a non-metal part passing through the slot; and   a radius of the curvature of the tooth is dependent on a thickness and a material of the workpiece.   
     
     
         20 . The apparatus of  claim 19 , wherein:
 the workpiece comprises a metal plate used in a VR device or a wearable consumer electronic device;   the bending block is supported by a fixed support;   the bending block is configured to bend the burr by pushing the tooth against the burr; and   the apparatus further comprises forging parts configured to replace the bending block to improve bending of the burr by further pushing the burr toward the fixed support.
