Working machine

Abstract

A working machine includes a work piece, at least one signal generator and a detector. The signal generator is disposed beside the work piece for transmitting a signal. The detector is disposed beside the work piece so as to detect the signal transmitted by the signal generator and get a location information of the work piece.

What is claimed is: 
     
         1 . A working machine, comprising:
 a work piece;   at least one signal generator disposed beside the work piece for transmitting a signal; and   a detector disposed beside the work piece so as to detect the signal transmitted by the signal generator and get a location information of the work piece.   
     
     
         2 . The working machine as recited in  claim 1 , wherein the work piece comprises a laser head or a polishing platform. 
     
     
         3 . The working machine as recited in  claim 2 , wherein the signal generator and the detector are disposed at the same side of the work piece. 
     
     
         4 . The working machine as recited in  claim 3 , wherein the detector is directly disposed on the work piece. 
     
     
         5 . The working machine as recited in  claim 1 , further comprising:
 at least one guide, wherein the signal generator, the detector and the guide are disposed at the same side of the work piece, the guide is directly disposed on the work piece, and the guide guides the signal transmitted by the signal generator to the detector.   
     
     
         6 . The working machine as recited in  claim 5 , wherein the signal generator and the detector are respectively located on two opposite sides of a normal direction of the guide. 
     
     
         7 . The working machine as recited in  claim 5 , wherein guide comprises a reflective mirror. 
     
     
         8 . The working machine as recited in  claim 1 , wherein the signal generator comprises an acoustic wave generator or a light wave generator. 
     
     
         9 . The working machine as recited in  claim 1 , wherein the detector comprises a matrix detector. 
     
     
         10 . The working machine as recited in  claim 1 , further comprising:
 a controller connected to the detector to receive the location information and generate an adjusting information; and   an adjuster connected to the controller and the work piece, wherein the adjuster receives the adjusting information and adjusts a location of the work piece based on the adjusting information.   
     
     
         11 . The working machine as recited in  claim 10 , wherein the controller comprises a computer. 
     
     
         12 . The working machine as recited in  claim 10 , wherein the adjuster comprises an actuator.
