Problems solved by technology

The emergence of multi-light source partition parallel scanning system has solved the problem of laser rapid prototyping machine making large-sized parts. The problem is: the use of multiple sets of lasers and scanning galvanometers will greatly increase the cost of rapid prototyping equipment due to their high prices. The volume and load of the optical circuit board of the system become larger

Abstract

The invention provides a regional mobile light source scanning system for a laser rapid prototyping technology. The system comprises a regional mobile platform, wherein the regional mobile platform is fixed in a working shell and arranged above a workpiece cavity; a linear motor platform of the regional mobile platform is suspended above the workpiece cavity through a connecting piece; a scanningplatform is fixed on the linear motor platform; a reflector of the scanning platform is positioned above a laser and a scanning mirror; the laser is positioned on the right of the scanning mirror; a computer with a scan control program is connected with the scanning platform through a mirror control card, and connected with the linear motor platform through a motion control card; before scanning,part data is input into the computer for partitioning, and is subjected to scan filling processing to determine whether a current region has data to be scanned or not, until all data are scanned. According to the regional mobile light source scanning system, the prototyping size of the laser rapid prototyping system is increased, and simultaneously high prototyping accuracy is maintained.

Description

technical field [0001] The invention belongs to the technical field of parallel rapid prototyping manufacturing, and in particular relates to a subregional mobile light source scanning system for laser rapid prototyping technology. technical background [0002] Laser rapid prototyping technology controls the laser to irradiate the forming material according to the CAD data of the read-in model parts. After the current layer is completed, add the material to be formed, and repeat the irradiation until the part is completed. [0003] As an important part of laser rapid prototyping technology, the scanning system plays a vital role in the size, forming efficiency and quality of the entire system. However, most of the existing rapid prototyping systems use a single scanning device, which cannot form large-sized parts at one time. . The concept of partitioned parallel processing has better solved the production problem of large-sized parts. For example, the patent named "Partiti...
