A linear robotic arm 3D printer

Abstract

The invention relates to a 3D printer with a linear robotic arm. In the 3D printer, slideways are both arranged on two sides at the upper part of a Y-axis slide rail; a Z-axis slide rail is arranged at the upper part of the Y-axis slide rail; rails on the two sides at the bottom end of the Z-axis slide rail are located in the slideways; a Z-axis slide block which can move up and down is mounted in front of the Z-axis slide rail; an X-axis arm is fixedly connected with the Z-axis slide block; a rotary arm capable of rotating by 360 degrees is mounted on the surface at one end of the X-axis arm; a printing head is mounted at the front end of the rotary arm; the Z-axis can move forwards and backwards on the Y-axis slide rail; the X-axis arm drives an X-axis arm lead screw to rotate through a stepping motor A; the X-axis slide block slides in the slideways; a rotary switch can be used for locating and adjusting the rotary arm capable of rotating by 360 degrees, so as to enable the printing head to print according to the requirement. When the robotic arm is used for performing 3D printing, the printing operation is not limited on a narrow printing platform, but like an open style, namely, at any ground or wall for actual practice; the printing joint capable of rotating is used for printing on the plane at any angle except for horizontal printing.

Description

technical field [0001] The present invention relates to the technical field of printing devices, in particular to a linear manipulator 3D printer. Background technique [0002] Since the advent of the linear robotic arm 3D printer, it has promoted the rapid development of the mold manufacturing and personalized portrait model industries, and has been praised as a new industrial technology revolution. The company launched the desktop-level linear robot developed by the FDM melting accumulation principle with the two major technologies of MAKERBOT and ULTIMAKER. The manipulator 3D printer greatly reduces the manufacturing cost of the linear manipulator 3D printer, and popularizes the use of the linear manipulator 3D printer to the private use field. At present, the printers developed, DIY and assembled based on the open source technology of the two companies are basically frame printers with 42 motors and synchronous belt transmission. The stepper motor drives the synchronous...

Problems solved by technology

Printing items can only be completed on the internal printing flat platform, affected by the size and structure of the frame, printed items can only print models much smaller than the frame size on the limited horizontal printing platform

This severely restricts the flexible use of linear robotic arm 3D printers, and the printed products can only print small parts. After printing, if they are to be formally installed and used in the outside world, technical cooperation such as bonding is required, resulting in a huge impact on the practicality of 3D printing. limitations
