Abstract
The invention discloses a technology for removing residual soldering flux after tin soldering. The technology includes the steps: immersing a tin soldering portion and an insulating sheath into an ethanol solution after a motor lead and a wire cable are welded, and cleaning the residual copper and aluminum soldering flux on the insulating sheath by ethanol, so that the residual copper and aluminum soldering flux is removed by means of neutralization of the ethanol to the copper and aluminum soldering flux. The technology has the advantages that the residual copper and aluminum soldering flux can be removed effectively, and no residual copper and aluminum soldering flux on the insulating sheath is guaranteed, so that corrosion and electric leakage of the insulating sheath are avoided.
Description
Technical field
The present invention relates to the removal technique of residual flux after scolding tin.
Background technology
During line welding in the market, without the technique of removing remaining scaling powder, after scolding tin, directly use.Because copper aluminium scaling powder has severe corrosive and electric conductivity, scaling powder residual after scolding tin can extend to insulating sleeve place, causes insulating sleeve to produce corrosion and leaky, thereby the security performance of motor is reduced.
Summary of the invention
The removal technique that the object of the present invention is to provide residual flux after a kind of scolding tin, it can effectively remove remaining copper aluminium scaling powder, guarantees that insulating sleeve place is without except remaining scaling powder, thereby avoids corrosion and the leaky of insulating sleeve.
For achieving the above object, technical scheme of the present invention is the removal technique of residual flux after a kind of scolding tin of design, after motor down-lead and cable welding, solder sections and insulating sheath are immersed in alcoholic solution, adopt alcohol to clean the remaining copper aluminium scaling powder on insulating sheath, utilize the neutralization of alcohol to copper aluminium scaling powder, remove remaining copper aluminium scaling powder.
Preferably, the concentration of described alcoholic solution is 40%-50%.
Advantage of the present invention and beneficial effect are: the removal technique of residual flux after a kind of scolding tin is provided, and it can effectively remove remaining copper aluminium scaling powder, guarantee that insulating sleeve place is without except remaining scaling powder, thereby avoid corrosion and the leaky of insulating sleeve.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
The concrete technical scheme of implementing of the present invention is:
As shown in Figure 1, the removal technique of residual flux after a kind of scolding tin, after motor down-lead and cable welding, solder sections and insulating sheath are immersed in alcoholic solution, adopt alcohol to clean the remaining copper aluminium scaling powder on insulating sheath, utilize the neutralization of alcohol to copper aluminium scaling powder, remove remaining copper aluminium scaling powder.
The concentration of described alcoholic solution is 40%-50%.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (2)
