Embodiment 1

[0008] The first embodiment of the present invention comprises the following steps: 1. Manufacturing a workpiece with a light-through hole and a positioning device, the workpiece has a high-precision plane; 2. Determining the position and direction of the laser beam; 3. Adjusting the light-through hole of the workpiece Make it concentric with the beam; 4. Adjust the angle of the workpiece so that the high-precision plane is perpendicular to the beam; 5. Fix the workpiece on the light emitting end of the laser. After this is done, the workpiece and the laser are integrated, and its aperture and positioning device (such as positioning pins) determine the exit position of the beam, while its high-precision plane determines the propagation direction of the beam.

Embodiment 2

[0010] The second embodiment of the present invention includes the following steps: 1. Place the laser that has been dimmed on the processing machine tool; 2. Determine the position and direction of the laser beam; 3. Determine the processing point and processing depth according to the position and direction of the beam; 4. Process reference features on the shape of the laser, and its position and direction have a definite relationship with the laser beam. After this is completed, the user can determine the position and direction of the beam according to these reference features.

[0011] The integration process does not require manual collimation of the optical path. It only needs to connect the downstream optical system to the device, and the optical path can be automatically collimated. The relatively centralized front-end process with relatively good equipment and personnel has even become one of the processes of laser production, which brings more convenience to laser equi...

Abstract

The invention discloses a laser beam aligning method. A downstream optical system is in butt joint with the device, an optical path is subjected to the automatic alignment, and the alignment and beam focusing of a laser device are transferred to a relatively concentrated front end process with relatively good equipment and personnel from a scattered terminal integrating process with limited equipment and personnel resources. According to the method, more conveniences are brought to laser device integrators and final users by using the laser device, the technical threshold of the integrating process is lowered, the effective utilization ratio of the laser device is increased, the demands on door-to-door after-sale service are reduced, and the application and popularization of the laser device are promoted.

Description

technical field [0001] The present method invention relates to the mass production of laser-based devices using standardized industrial processes. Background technique [0002] Carbon dioxide laser technology has increasingly penetrated every branch of the manufacturing industry through laser marking machines, laser engraving machines, and laser cutting machines (referred to as laser equipment). However, the production of carbon dioxide lasers is basically based on the specifications of each manufacturer, and there is no unified standard. Due to errors in manufacturing, the output position and direction of the beam of laser products cannot be determined according to the accuracy required in use, and the output beam is invisible infrared light, which brings difficulties to the integration of laser equipment. The current integration of laser equipment requires well-trained optical engineering personnel, and careful dimming with special equipment is required during the integra...
