Large-space 3D printing machine based on light mechanical arm

Abstract

The invention relates to the technical field of printing equipment, in particular to a large-space 3D printing machine based on a light mechanical arm. The printing machine comprises a supporting frame, the supporting frame is provided with an X-axis cross beam, a Y-axis cross beam capable of sliding in the length direction of the X-axis cross beam is arranged on the X-axis cross beam, a Z-axis cross beam sliding in the length direction of the Y-axis cross beam is arranged on the Y-axis cross beam, the Z-axis cross beam is connected with a three-freedom-degree mechanical arm and a steel rope-spring traction device through a Z-axis vertical beam, and the three-freedom-degree mechanical arm and the steel rope-spring traction device. Due to the structure, Z-axis direction control of the 3D printing machine is achieved through the mechanical arm, spaced occupied in the Z-axis direction is small, large-space printing is achieved, the weight of the mechanical arm is reduced, the motor running power is reduced, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a large-space 3D printer based on a light mechanical arm. Background technique [0002] There are two main ways to move the Z axis of 3D printing technology: one is to fix the nozzle on the plane where the X and Y axes are located, and realize the movement in the direction of the Z axis by controlling the overall movement of the plane where the X and Y axes are located; The plane where the Y axis is located can move in the direction of the Z axis through the expansion and contraction of the telescopic arm. These two methods have relatively large space restrictions. The first method is not stable enough for printing larger products and lacks precision. The second method requires a certain buffer space for the telescopic arm itself, and the non-working state space occupies bigger. In addition, the 3D printing of large buildings uses a mechanical arm to control the move...

These two methods have relatively large space restrictions. The first method is not stable enough for printing larger products and lacks precision. The second method requires a certain buffer space for the telescopic arm itself, and the non-working state space occupies bigger

In addition, the 3D printing of large buildings uses a mechanical arm to control the movement in the three directions of X, Y, and Z. However, the mechanical arm has a high load-bearing capacity and requires a large amount of power for the motor.
