Stirring method

Abstract

The invention provides a stirring method, comprising: providing a weld pool in which molten solder is arranged; arranging a mixer on the weld pool, wherein the mixer comprises a power assembly, a transmission assembly and a assembly. The transmission assembly comprises a substrate, and an output shaft and a driven wheel fixing shaft which are fixed on the substrate and are arranged un and down, the output shaft can be driven by the power assembly to rotate, a drive wheel and a driven wheel are respectively fixed on the output shaft and the driven wheel fixing shaft, the drive wheel is engaged with the driven wheel, and an engaging piece of the drive wheel and the driven wheel is lower than a minimum point of a connecting part between the output shaft and the substrate. The stirring assembly comprises main stirring shaft and an auxiliary stirring shaft which are respectively and fixedly connected to the output shaft and the driven wheel fixing shaft, and the stirring vanes are respectively arranged on the main stirring shaft and the auxiliary stirring shaft. The method further comprises steps of: controlling the mixer, to enable the drive wheel and the driven wheel to be immersed in the molten solder, wherein a liquid level of the molten solder is higher the engaging piece between the drive wheel and the driven wheel, and is lower than the minimum point of the connecting part between the output shaft and the substrate; and driving the main stirring shaft and the auxiliary stirring shaft to rotate, for stirring. The stirring method can avoid the mixer being locked deadly, and is convenient for using.

Description

technical field [0001] The invention relates to a stirring method, in particular to a stirring method used in a molten pool of wave soldering. Background technique [0002] In industrial production, it often involves the process of melting a metal or alloy to combine or adhere to another metal. Since most metals will be oxidized in contact with oxygen, such as tin slag (SnO and SnO) produced in a static tin furnace or a dynamic wave furnace 2 ) is one of the most common examples of metal oxidation in industry. In a high-temperature environment, especially in a molten state, the oxidation of the metal (or alloy) will be more severe, and a layer of oxide will soon be formed, and the more it gathers. In the process of adhesion and bonding of molten metal and other metals, the molten metal must be continuously flowed and circulated, which will intensify the oxidation rate on the one hand, and on the other hand mean that the oxides on the surface and a small amount of oxygen wi...

Problems solved by technology

[0004] In order to overcome the problem that the stirring method in the prior art is likely to cause the mixer to be stuck by tin slag and other dirt during the stirring process and cannot be used normally, the present invention provides a stirring method, which can effectively prevent the mixer from being stuck by tin slag. Stuck, improve work efficiency, and easy to use
