High-precision portable scanner

Abstract

The present invention discloses a high-precision portable scanner which comprises a supporting mechanism and an overturning mechanism, a supporting disc is fixedly installed on one side of the overturning mechanism, a first collecting cavity, a second collecting cavity, an adjusting cavity and an annular protective cover are arranged on one side of the supporting disc step by step, and a transmission cavity is installed in an inner cavity of the second collecting cavity; and a processing plate is installed on one side of the transmission cavity, a second heat conduction silica gel gasket is attached to one side of the processing plate, and a driving motor and a connecting plate are fixedly installed in the transmission cavity. Driving teeth are arranged for rotation and meshed with driven teeth for rotation, the diameter of the driving teeth is smaller than that of the driven teeth, the transmission ratio is increased, then a reciprocating rod is driven to rotate along the interior of a connecting plate, and then a sliding plate is driven to be meshed with the surface of the reciprocating rod for reciprocating sliding; and therefore, the optical acquisition scanning assembly is enabled to perform rapid focusing adjustment in the annular protective cover, the image acquisition precision is improved, and the acquired image quality is improved.

Description

technical field [0001] The invention belongs to the technical field of scanning, and in particular relates to a high-precision portable scanner. Background technique [0002] A scanner is a device that uses photoelectric technology and digital processing technology to convert graphics or image information into digital signals in a scanning manner. Scanners are usually used for computer peripheral equipment, by capturing images and converting them into computers that can be displayed and edited. , storage and output of digital input devices, scanners can be used as scanning objects for three-dimensional objects such as photos, text pages, drawings, art drawings, photographic negatives, film films, and even textiles, sign panels, printed board samples, etc., to extract and convert The original lines, graphics, text, photos, and flat objects are converted into devices that can be edited and added to the file. The purpose of the 3D scanner is to create the geometric surface of t...

Problems solved by technology

[0005] When the scanner scans a large object, it needs to manually move its position. The speed of manually moving the scanner keeps changing, and the scanned image is not accurate enough. After the scanner position is fixed, the scanning angle of the scanner cannot be changed according to the scanning needs and is inconvenient to carry.
