Flux applicator

Abstract

The invention discloses a flux coating device. For the present invention, a fixed bar equidistantly arranged on the spray tube, and a spray head of a caliber corresponding to the movable connection is arranged on the fixed bar, and the spray tube is sprayed with flux. It can be equipped with nozzles of various calibers, and the nozzles of different calibers can be replaced according to the actual situation, so as to ensure the quality of coating, ensure the quality of welding work, and improve the economic efficiency of the work; when using nozzles of different calibers, through The connection and locking mechanism set up is very convenient and fast for the conversion of nozzles with different calibers. It will not delay the coating work and ensure the processing efficiency. It can also ensure the connection between the nozzle and the nozzle while ensuring the conversion and coating efficiency. The firmness and stability of the coating can ensure the stable progress of the coating work.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a flux coating device. Background technique [0002] Flux (flux): a chemical substance that can help and promote the welding process in the welding process, and at the same time has a protective effect and prevents oxidation reactions; fluxes can be divided into solid, liquid and gas; mainly include "auxiliary heat conduction", "removal of oxidation material", "reduce the surface tension of the material to be welded", "remove the oil stain on the surface of the material to be welded, increase the welding area", "prevent re-oxidation", etc. There are two key functions in these aspects: : "Remove oxides" and "reduce the surface tension of the material to be welded". The flux is usually a mixture of rosin as the main component, which is an auxiliary material to ensure the smooth progress of the welding process; welding is the main process in electronic assembly. It is an ...

Problems solved by technology

[0003] It can be seen that in the welding process of the prior art, the role of flux is very important. For the coating of flux, a flux coating machine is usually used, and the coating work is usually carried out in the form of nozzle spray. Among them, the diameter of the coating nozzle is fixed. When the part to be coated is too large, reciprocating coating is required, which makes it difficult to control the quality of the coating and increases the workload. When the coating part is small, it will The parts that are not needed are also coated, which leads to a waste of flux. Therefore, it is usually either to replace different types of equipment for coating work, or to change the diameter of the nozzle. Under the existing technology, it is too troublesome to replace the nozzle, which affects The normal progress of the welding work reduces the work efficiency, and affects the welding quality and reduces the economic benefits of the work. For this reason, the present invention proposes a flux coating device to solve the above problems
