Head switching device for 3D printing

Abstract

The invention relates to a head switching device for 3D printing, and belongs to the field of design and manufacturing of mechanical equipment, in particular to the multi-printing-head head switching device in the field of design and manufacturing of 3D printing equipment. The head switching device is composed of a head switching support, a printing head grabber, a printing head storage module, a printing head wire connector and a printer moving mechanism. The printing head grabber is fixed on the printer moving mechanism; and the printing head storage module and the printing head wire connector are fixed on the head switching support. According to the device, a plurality of printing heads of a printer are designed into columns and are respectively placed in the corresponding printing head storage module, and the printer grabs and returns the printing heads according to program control, so that the switching of the printing heads is realized. The head switching device for 3D printing has the advantages that the limitation on expansion of the number of the printing heads of the 3D printer is broken through, calling or returning of the split printing heads is achieved in a modular assembling manner, and the head switching device for 3D printing is of great significance to improvement of flexibility of the printer.

Description

technical field [0001] The invention belongs to the field of mechanical equipment design and manufacture, in particular to a head changing device in the field of 3D printing equipment design and manufacture. Background technique [0002] With the development of science and technology, 3D printing technology is used more and more widely. At present, 3D printers on the domestic and foreign markets include single-print head printers and multi-print head printers. The print heads of multi-print head printers include two types: split print heads and integrated print heads. In the field of multi-print heads, the integrated print head is mainly used, and the split print head mainly includes a double X and double Y structure. With the development of technology, the demand for 3D printing tends to be more and more diversified, and the future development direction of 3D printers is also more and more inclined to multi-printing heads, such as multi-color printing, multi-material print...

AI Technical Summary

Problems solved by technology

[0003] In view of the above problems, the present invention provides a multi-print head replacement device, which mainly solves the problem that the number of separate print heads in the prior art is difficult to expand, breaks through the limitation of the number expansion of print heads, and adopts the modular assembly method Realizing the call or return of the split print head can well solve the problem of print head expansion, which is of great significance for improving the flexibility of the printer
