Description

Technical Field

[0001] The utility model relates to a scanning frame, in particular to a slide rail type scanning frame, belonging to the technical field of scanning. Background Art

[0002] 3D printing is a rapid prototyping technology, sometimes also called additive manufacturing. It is mainly based on digital model files and uses adhesive materials such as powdered metal or plastic to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers. Before printing, the printed materials need to be digitally modeled. Therefore, before the 3D printing process, it is usually necessary to use a scanner to scan and model the objects to be printed.

[0003] Usually, when scanning smaller objects, the smaller objects are placed on the scanning table, and the scanner moves horizontally through two slide rails on the scanning frame to scan the smaller objects. When scanning larger objects or human bodies, the scanner body needs to scan the objects or human bodies from top to bottom. Since the two slide rails on the existing scanning frame are arranged horizontally but cannot be adjusted vertically, the scanner body cannot be used for up and down scanning, resulting in the inability to scan larger objects or human bodies, which reduces the practicality of the device. Utility Model Content

[0004] 1. Technical issues to be solved

If a larger object or a human body is to be scanned, and the scanner body needs to scan the object or the human body from top to bottom, because the two slide rails on the existing scanning frame are arranged in the horizontal direction but cannot be adjusted vertically, the scanner body cannot be used for up and down scanning, resulting in the inability to scan larger objects or human bodies, thereby reducing the practicality of the device.
