Embodiment

[0039] Such as figure 1 As shown, an ignition needle welding process provided by the embodiment of the present invention, the ignition needle includes a needle body, a lead wire and an insulating sleeve, and a through hole for inserting the needle body and the lead wire is provided through the insulating sleeve along its length direction.

[0040] Described welding process comprises the following steps:

[0041] S1. Take a certain amount of slurry solder and inject it into the insulating sleeve;

[0042] Specifically, it includes taking a certain amount of slurry-like solder and injecting it from the upper end of the insulating sleeve so that the solder is agglomerated at the first position, wherein the solder is configured as a slurry so that after the solder is filled in the insulating sleeve, it can be combined with the insulation There is a large friction force between the inner walls of the sleeves, so as to prevent the solder injected from the upper end from flowing out...

Abstract

The invention belongs to the technical field of gas stove ignition, and particularly relates to an ignition needle welding process. A certain amount of slurry brazing filler metal is injected into an insulating sleeve; respectively inserting the needle body and the lead in place from the upper and lower ends of the insulating sleeve; the ignition needle welding method is used for solving the problem that a conventional ignition needle is low in assembly efficiency.

Description

technical field [0001] The invention belongs to the technical field of gas stove ignition, and in particular relates to an ignition needle welding process. Background technique [0002] The ignition needles currently on the market are usually composed of a needle body, a lead wire and a ceramic insulating sleeve. The traditional process is usually used for assembly. High temperature glue is poured into the insulating sleeve for encapsulation. [0003] In this welding assembly method, in the actual production process, there will be welding between the lead wire and the needle body. Due to the error prone to occur in the welding, a welding bump will be formed at the welding place between the needle body and the lead wire, which will make the needle body and the lead wire welded into one It is difficult to install through the ceramic insulating sleeve. Products with poor welding need to be polished, which affects the installation efficiency. In addition, when injecting high-te...
