Problems solved by technology
The manual operation method needs to be soaked in acid solution and cleaning agent solution for a long time, the soaking time is long and the efficiency is low; the surface quality after soaking and rinsing is uneven, which often leads to a lot of rework; In the process, the waste of water resources, acid liquid and cleaning agent solution caused by human is not easy to control, which makes the processing cost higher
The cleaned brazing filler metal is directly dried, which takes a long time, and the surface of the dried brazing filler metal is prone to water marks and surface oxidation.
There is no automatic cleaning equipment and cleaning process specially designed for rod-shaped solder in the market, which hinders the improvement of the surface quality of the solder alloy and affects the performance of the solder

Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.
[0025] Example.
[0026] In this embodiment, the method for cleaning rod-shaped solder includes the following steps.
[0027] 1) First, the rod-shaped solder is cleaned in an aqueous solution of a cleaning agent with a mass percentage concentration of 2-5%, and the cleaning time is 180-240 seconds; this operation is carried out in the degreasing tank 2.
[0028] 2) Rinse the rod-shaped solder with water for 30-60 seconds; this operation is performed in the rinsing tank 3 . In this embodiment, the water used generally refers to tap water or the water used in the last flushing.
[0029] 3) Use a sulfuric acid solution with a mass concentration of 8-12% for deoxidation polishing. The deoxidation polishing time is 180...

The invention relates to a bar-like brazing filler metal cleaning method, comprising the following steps of (1), cleaning the bar-like brazing filler metal in an aqueous solution with the mass percentage concentration of a cleaning agent being 2-5% for 180-240 seconds; (2), washing the bar-like brazing filler metal by water for 30-60 seconds; (3) performing oxidizing and polishing by using a sulfuric acid solution with the mass concentration of 8-12% for 180-240 seconds, wherein the sulfuric acid solution contains a brightener with the mass part of 0.5-1%; (4) then carrying out rinsing for 30-60 seconds and detergent washing for 30-60 seconds; and (5) performing passivation in a benzotriazole solution with the mass concentration of 0.3-0.8% for 5-20 seconds. The invention also relates to a bar-like brazing filler metal cleaning device for realizing the method.
Description
technical field [0001] The invention relates to a method for cleaning rod-shaped solder, and also relates to a rod-shaped solder cleaning device for realizing the method. The cleaning device belongs to matching cleaning equipment for brazing material processing. Background technique [0002] In recent years, with the application of brazing materials in high-end fields such as aviation, aerospace, nuclear energy, and electronics, higher requirements have been put forward for the quality and surface quality of brazing materials. However, how to improve the cleaning quality of the alloy solder surface after production has always been an urgent problem to be solved. At present, the common cleaning method of rod-shaped solder is manual operation. Dry. The manual operation method needs to be soaked in acid solution and cleaning agent solution for a long time, the soaking time is long and the efficiency is low; the surface quality after soaking and rinsing is uneven, which often l...
