Dual-output 3D printing four-degree-of-freedom decoupling parallel robot

Abstract

The invention discloses a dual-output 3D printing four-degree-of-freedom decoupling parallel robot, relates to the field of robots, and belongs to the category of 3D printing technology, wherein the 3D printing robot can print two same products simultaneously by using a traditional 3D printing way and can be used for the printing of inclined surfaces, the restoration of objects and the secondary processing of complex environments. The dual-output 3D printing four-degree-of-freedom decoupling parallel robot comprises a base component, movement branched-chain components, print nozzle components and connecting rods, wherein symmetric U-shaped sliding blocks in the base component are connected with the connecting rods through mounting shafts, shaft bushes and bearings to form a first rotating pair; the connecting rods in the movement branched-chain components are connected through the mounting shafts, the shaft bushes and the bearings to form a second rotating pair; the connecting rods are connected with U-shaped connectors of movable platforms in the print nozzle components through the mounting shafts, the shaft bushes and the bearings to form a third rotating pair; the sliding blocks do linear movement along guide rails to drive the movement branched-chain components to move, so that the two print nozzle components realize pitching and translational movement.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a dual-output 3D printing four-degree-of-freedom decoupled parallel robot. Background technique [0002] 3D printing technology is a kind of additive manufacturing technology. It uses computer-aided design of three-dimensional models, and uses layering software to layer the three-dimensional models and plan the trajectory of the 3D printing robot nozzle, and print physical products layer by layer. 3D printing technology has changed the traditional manufacturing method, shortened the cycle of manufacturing products, and improved work efficiency. With the development of 3D printing technology, printing materials and equipment have been continuously innovated, and the molding speed and precision have been continuously improved. It has been widely used in automotive, aviation, medical, teaching and other fields. 3D printing robots suitable for home and office are getting more and mor...

Problems solved by technology

[0003] At present, most of the commercial 3D printing robots are tandem mechanisms. Due to the characteristics of tandem mechanisms, their printing speed and printing accuracy are affected.

However, most of the existing parallel mechanism 3D printing robots have only one output, and can only print one product at a time. Even if some serial 3D printers can print two products at the same time, they are greatly affected by the working space, and the size of the printed product is greatly affected. big limit
