Embodiment Construction

[0036] The multi-vibrating mirror calibration method provided by the present invention uses a contact scanner to collect images of the target arrays on the calibration board produced by multiple vibrating mirrors, and after processing the collected target arrays through the image processing module, outputs a plurality of vibrating mirrors. The compensation information of the mirror and the splicing information between the galvanometers are used to correct the galvanometer; the galvanometer can be calibrated with low cost, high efficiency and high precision without the aid of auxiliary measuring equipment.

[0037] figure 1 The module structure of the galvanometer correction system provided by the present invention is shown, and its working principle is described in detail as follows.

[0038] The galvanometer correction system 3 includes a galvanometer correction plate 31, a contact scanner 32 and an image processing module 33, wherein the optical path transmitter 1 emits an o...

Abstract

The invention discloses a quick calibration method for multiple vibrating mirrors. The calibration method comprises the following steps: beams sent by a plurality of vibrating mirror control light path emitters of a vibrating mirror control system project a target array on a vibrating mirror correcting plate; the vibrating mirror correcting plate is placed on a contact scanner and an operation contact type scanner collects a target array image; and an image processing module acquires relative coordinate values of the target array of the vibrating mirrors and rotating and translating amounts thereof by means of the collected target array image. The quick calibration method for multiple vibrating mirrors can project the target array of the vibrating mirrors at one time, collect the target array image by using the cheap contact type scanner and process the collected image by the image processing module to output splicing information of a plurality of single vibrating mirror compensation files and multiple vibrating mirrors so as to calibrate the vibrating mirrors with low cost, high efficiency and high precision, and meanwhile, the quick calibration method for multiple vibrating mirrors is suitable for arranging the vibrating mirrors in any form.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a multi-vibrating mirror rapid calibration method. Background technique [0002] In the field of additive manufacturing technology, the galvanometer is generally used to control the light (laser, etc.) path to irradiate the powder (metal, resin, etc.) to solidify it to form complex parts; environmental changes such as temperature, humidity, vibration, and mechanical wear of the motor, etc. , causing the galvanometer motor to lose steps, and a deviation will occur after a certain period of time, which will affect the molding quality of the part. Therefore, it is necessary to perform error compensation on the galvanometer in time to reduce the deviation. [0003] In the process of using the galvanometer for high-precision laser processing, it is often necessary to impose strict requirements on the processing accuracy of the galvanometer. Therefore, the pr...
