Movable-robot-type liquid metal printing device and method

Abstract

The invention discloses a movable-robot-type liquid metal printing device and method. The device comprises a control unit, a driving unit, a moving unit, an attaching unit and a printing unit. The working method comprises the following steps: 1, the control unit analyzes the liquid metal route required to be printed and sends a control instruction to the driving unit; 2, the driving unit controls the moving unit and the attaching unit, so that the whole device moves to a designated position of space and stably attaches to a working surface; 3, the printing unit prints the liquid metal or a packaging material on the surface of the working surface by automatically adjusting a spraying head; and 4, the device can also move according to instructions to realize multi-area continuous printing. The device can automatically move to the working surface at different positions of the space to directly carry out printing and packaging of the liquid metal route, so that various limitations of a fixed device on printing size, position and the like are broken, and the rapid manufacturing efficiency and the personalized degree of the liquid metal electronic route are further improved.

Description

technical field [0001] The invention relates to the technical field of circuit printing, and more specifically relates to a mobile robot type liquid metal printing device and method. Background technique [0002] Liquid metal is a general term for a series of low-melting point metals and alloy materials. As a conductive material, liquid metal can be directly printed on various substrate materials because it can be fluid at room temperature or at a lower heating temperature. surface, enabling rapid additive manufacturing of electronic circuits. Compared with the processing of traditional copper-clad printed circuits, liquid metal printed circuits are fast, suitable for a variety of substrates, and can print circuits on curved surfaces; in addition, compared with traditional copper-clad printed circuits, the processing process of liquid metal printed circuits More energy saving and environmental protection. [0003] At present, the printing methods of liquid metal can be rou...

Problems solved by technology

[0004] However, the existing liquid metal printing equipment is a single fixture, which needs to feed the substrate material to be printed first, and then place, attach or transfer the substrate printed with the liquid metal circuit to the desired scene However, the use process is complicated, and the size of the printed circuit is limited by the design size of the equipment. Especially in many application scenarios, the surface to be printed is located in a special position such as a wall or a ceiling, or it cannot be sent to print by non-destructive means. equipment, which greatly limits the scope of application of rapid manufacturing of liquid metal electronic circuits
