Laser drilling equipment and drilling method with automatic detection of the highest point position of the sphere

Abstract

The invention discloses a laser drilling device capable of automatically detecting the highest point position of a sphere and a drilling method. At present, laser drilling is performed manually, the position of material to be machined is detected through a sensing system, the focusing position is sensed by means of the visual sense of an operator, and then a motion control system is adjusted manually to reach the designated position to perform laser drilling device. The laser drilling device capable of automatically detecting the highest point position of the sphere comprises a drilling machine, an automatic detecting system is formed by a high-resolution coaxial CCD sensor and an image collecting card and connected with a computer provided with a high-precision motion control card, the high-precision motion control card is connected with a stepping motor of the drilling machine, image processing software is installed on the computer, and the highest point position of the sphere is focused accurately and rapidly through the automatic detecting system. The laser drilling device is used for laser drilling at the highest point position of the sphere.

Description

technical field [0001] The invention belongs to the technical field of automatic detection of the position of the highest point of a sphere in a laser drilling system, and in particular relates to a device and method for accurately automatically positioning the position of the highest point of a sphere and drilling holes. Background technique [0002] In the process of laser drilling, in order to ensure the shape and size requirements of the hole, it is necessary to determine the focus position of the laser and ensure that the focus position remains constant. For the laser drilling at the highest point of the sphere, the accuracy of the focus of the laser beam on the highest point of the sphere is a key factor to ensure the shape and size of the hole. [0003] At present, in the process of laser drilling, it is still mainly under human operation. The sensing system detects the position of the processed material, and relies on the operator's vision to perceive the focus posit...
