Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser calibration equipment technology, specifically a laser rapid calibration device. Background Technology
[0002] In industrial manufacturing, automated assembly, and construction surveying, laser calibration devices serve as precision positioning tools, and their performance directly impacts production efficiency and product accuracy. However, existing laser calibration equipment still faces many challenges in practical applications, making it difficult to meet the demands of complex scenarios. Low angle adjustment accuracy and insufficient calibration flexibility Traditional laser calibration devices often employ a fixed-angle design or only support coarse-adjustment angle adjustment (such as changing the angle by directly pushing the component with a bolt). This adjustment method is prone to over-adjustment or adjustment dead zones, making it difficult to achieve precise fine-tuning, resulting in the laser spot not being accurately aligned with the calibration baseline. Low modularity and high installation and maintenance costs The laser emitting components of existing equipment are mostly integrated with the mounting base using a design that involves welding or multiple screws. During assembly, each laser tube, lens, and control board must be aligned with its mounting position, which is cumbersome and requires highly skilled assemblers. More importantly, when a single laser tube is damaged or a lens is contaminated, the entire mounting base must be disassembled or even the entire device must be replaced, making targeted repair impossible.
[0003] Poor scene adaptability Different application scenarios have different requirements for the number of laser emitters and the type of laser spot, but the number of laser emitter components in existing equipment is fixed and cannot be flexibly increased or decreased according to the scenario. Therefore, we have made improvements to this and proposed a rapid laser calibration device. Utility Model Content
