Abstract
The invention discloses a manufacturing method of a wireless power transmission coil forming groove tray. The method comprises the following steps: (1) building a wireless power transmission efficiency optimization objective function; (2) inputting parameters such as transmitting coils and receiving coils and the like into the objective function and solving to obtain a transmitting coil geometrical parameter and a receiving coil geometrical parameter with optimal wireless power transmission efficiency; (3) generating a model of a groove tray for forming the transmitting coils and the receiving coils via software; and (4) printing the groove tray for forming the transmitting coils and the receiving coils via a 3D printer. Through the manufacturing method of the wireless power transmission coil forming groove tray, the parameters of wireless power transmission are directly converted into the parameters needed by the coils, then the parameters needed by the coils are directly used for producing corresponding power transmission coils; the transmitting coils and the receiving coils with optimal transmission power can be produced; the produced groove tray is capable of greatly improving the working efficiency of winding the power transmission coils and is high in coil groove accuracy; meanwhile, the wire groove in the groove tray is capable of effectively fixing the coils; the deformation problem in the coils in the using process can be solved.
Description
technical field [0001] The invention relates to the technical field of Archimedes spiral coils, in particular to a method for manufacturing an Archimedes spiral coil molding die. Background technique [0002] Wireless power transmission is currently in a vigorous development process, but the production of wireless power transmission coils for laboratories is still at a very primitive stage, often done by hand. [0003] There are two main problems in artificially making wireless power transmission coils: [0004] 1. The accuracy of handmade power transmission coils is low, and the coils produced lack effective shape fixing devices, which makes the coils prone to deformation during use, and the power transmission efficiency of handmade coils often cannot reach the theoretical value. And this will have a very adverse effect on the experiment. [0005] 2. The production efficiency of manual coil winding is low, and the winding work is very cumbersome, which brings unnecessary ...
