Title: Etch machining device
Inventor: ONO AKIRA
IPC: H01J31/20
Filed: 1979-03-06
Abstract: PURPOSE: To always enable constant etch machining of plate material even when its thickness changes, uniformalize its quality, and improve its precision by optically measuring the plate material thickness and controlling the etching conditions based on its result.  
     CONSTITUTION: A pair of displacement measuring instruments 6 and 6 are installed through the head shielding body 9 with the transparent window 8 so as to face the upper and lower surfaces of the plate material 3 which is carried on the conveyance path 1. This instrument 6 focuses the laser beam L from the laser oscillator 10 by the condenser lens 11 and irradiates it on one side of the plate material 3. The displacement on one side of the plate material 3 is measured by detecting its reflected light L 1  through the imaging lens 11 by the optical point position transducers 13. These pairs of position transducers 13 are connected to the arithmetic unit 14. The first and second driving sources 17 and 18 and the heater 16 are controlled by the signals from the arithmetic unit 14. This can uniformalize the quality of the plate material and improve its precision.
