Soldering flux coating device

Abstract

The invention discloses a soldering flux coating device. Fixing strips are arranged on a spray pipe at equal intervals, spray heads with one caliber are correspondingly and movably connected to the fixing strips, the spray heads with various calibers can be attached to the spray pipe when the spray pipe conducts soldering flux powder spray coating work, spray heads with different calibers can be replaced for coating work according to actual condition requirements, so that the coating quality is guaranteed, the welding work quality is guaranteed, and the work economic benefits are improved; andwhen spray heads with different calibers are used, the spray heads with different calibers can be switched and used very conveniently and quickly through an arranged connecting and locking mechanism,the coating work cannot be delayed, the processing work efficiency is guaranteed, the switching and coating work efficiency is guaranteed, and meanwhile, the firmness and stability of connection between the spray heads and the spray pipe can be guaranteed, so that the stable operation of the coating work is ensured.

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
