Destructive and visual measurement automation system for web thickness of microdrills and method thereof

摘要

An improved destructive and visual measurement automation system and a method for measuring a web thickness of a microdrill are provided. When a dual-axis motion platform module moves the microdrill to a first position, a reflection module reflects a first image in a first direction toward a second direction. A vision module receives the reflected first image in the second direction and outputs the received first image to a computer. According to the first image, the computer performs a positioning procedure and a grinding procedure to drive a drill grinding module to grind the microdrill to a sectional position to be measured of the microdrill. When the microdrill is moved to a second position, the vision module outputs a second image to the computer. According to the second image, the computer performs an image computing procedure to obtain the web thickness at the sectional position to be measured.

1. An improved destructive and visual measurement automation system for measuring a web thickness of a microdrill, comprising:
a computer; a dual-axis motion platform module, electrically connected to the computer and configured to hold the microdrill and be controlled by the computer to move the microdrill; a drill grinding module, electrically connected to the computer and configured to grind the microdrill to a sectional position to be measured to form an axial cross-section of the microdrill when the dual-axis motion platform module moves the microdrill to a grinding position; a reflection module, configured to reflect a first image, which presents a drill tip of the microdrill and the drill grinding module, in a first direction toward a second direction when the dual-axis motion platform module moves the microdrill to a first position at which the microdrill does not contact with the drill grinding module; and a vision module, electrically connected to the computer, wherein when the vision module acquires the reflected first image in the second direction and outputs the acquired first image to the computer, the computer obtains a first distance between the drill grinding module and the drill tip of the microdrill according to the acquired first image; and then when the dual-axis motion platform module moves the microdrill to a second position at which the microdrill is in an image capture region of the vision module, the vision module acquires a second image, presenting the axial cross-section of the microdrill at the sectional position to be measured, in the second direction and outputs the second image to the computer, and the computer calculates the web thickness of the microdrill at the sectional position to be measured according to the second image; wherein the computer controls the drill grinding module according to the first distance and the sectional position to be measured to grind the microdrill to the sectional position to be measured.
