Galvanometer correction system and correction method thereof

Abstract

The invention discloses a galvanometer correction system. The galvanometer correction system comprises an optical path transmitter, a galvanometer control system and a galvanometer correction system.The optical path transmitter is used for transmitting light beams; the galvanometer control system is used for controlling the light beams transmitted by the optical path transmitter to deflect and mark a target array and sintering the target array on the galvanometer correction system; the galvanometer correction system is used for receiving the light beams transmitted by the optical path transmitter so as to form the target array and generate a galvanometer compensation file. The galvanometer correction system comprises a contact-type scanner, and two sets of parallel inclined lines fixed atintervals are embossed at the outer side of a light-transmission glass plate of the scanner and are in perpendicular intersection to form multiple evenly-arrayed cross points. The invention further discloses a correction method of the galvanometer correction system. The contact-type scanner is used for conducting image collection on the target array on a galvanometer correction plate, the collected target array is processed through an image processing module, and galvanometer compensation is output for correcting the galvanometer. Without assistance of auxiliary measurement equipment, the galvanometer can be corrected with low cost, high efficiency and high precision.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, relates to a vibrating mirror correction system, and also relates to a correction method using the vibrating mirror correction system. 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 field of additive manufacturing technology, the target array is usually printed on the calibration plate, and then the expensive auxi...
