技術說明

一種光電式刀尖位置精密感測裝置，設有一撞擊組、一光學組及一感測組，該撞擊組設有一外殼體、一撞擊座與一彈性元件，該光學組與撞擊組相結合且設有一楔形鏡架、一發射器及一第二反射鏡，該楔形鏡架與撞擊座相結合且設有一第一反射鏡，該發射器朝第一反射鏡射出光源，該第二反射鏡接收第一反射鏡的反射光源，該感測組與撞擊組及光學組相結合且設有一位置靈敏感測器及一放大電路，該位置靈敏感測器接收第一反射鏡的反射光，該放大電路與位置靈敏感測器相連接，當光點位置有極微小變化時即可偵知，故可提供一準確偵測刀尖位置的感測裝置者。 A precision optoelectronic inspection device that consists of a stroke module, an optical module and a sensing module can be utilized for sensing the cutter tip position. The stroke module including housing, a fixture and a spring is combined with the optical module which contains a wedge stand, an emitter and a reflector (No. 2). A reflector (No. 1) is mounted on the wedge stand that is fixed on the fixture. The laser beam is emitted from the emitter to the reflector (No.1), and is then reflected between the two reflectors (No.1 and No.2). In the sensing module there is a PSD and an amplifier circuit. The reflected beam is finally received by the PSD and through the amplifier circuit connected to PSD the tiny position variation of laser beam can be detected. Therefore, a compact and accurate inspection device for sensing the cutter tip position can be realized.
