Wire Tinning Machine: Common Faults and Corresponding Solutions

The requirements for products processed by fully automatic wire tinning machines are becoming increasingly stringent in modern manufacturing. Not only must the wires be neatly twisted and the tinning be uniform and smooth, but some products also demand full-tinning of wire ends and precise tinning at designated points. Let’s explore the potential issues that may arise with these requirements and address them one by one.

Full-Tinning of Wire Ends:

Tinning not fully complete, with slight tin residue near the insulation.
Tin is fully applied, but the insulation is burnt or contracted.
Visual inspection under a microscope reveals unevenness, gaps, tin tips, or large heads.
Point Tinning of Wire Ends:

Deviation in the specified tinning length.
Visual inspection after tinning at the specified length reveals unevenness, gaps, tin tips, or large heads.
To address the above issues, it is crucial not only for the tinning device components on the fully automatic wire tinning machine to be designed reasonably and easy to adjust but also for the raw materials (i.e., tin bars, tin wires, flux) to meet high standards. The viscosity of high-temperature tin versus regular tin, as well as the strength of the flux, plays a crucial role. The use of a stepper motor to control the rotation of the fixture by 90 degrees for horizontal contact with the tin furnace surface, an environmentally friendly titanium material for the tin furnace, a temperature controller, and a 200W heating tube are employed to ensure the stability of the tin furnace temperature. Convenient height adjustment and precise 90-degree rotation positioning are crucial. The incorporation of automatic solder feeding ensures the horizontal capacity of the tin furnace surface, followed by temperature adjustment based on wire size and screen adjustment of the flux position. With these measures, the aforementioned issues can be entirely avoided.

For full tinning, it is essential for the flux to have strong viscosity. When 2/3 of the wire core enters the flux holder, a 90-degree rotation into the tin furnace ensures that the tin surface is approximately 1mm away from the insulation. This prevents burning the insulation or incomplete tinning. If the tinning is not smooth and has gaps, adjustments to the tin furnace temperature and tinning time can resolve the issue. Tin tips or large heads are generally caused by inadequate wire twisting, which can be corrected by adjusting the wire twisting.

For point tinning, the flux should have low viscosity. The amount of tin applied corresponds to the amount of flux adhered to the wire core. The tin furnace temperature must be suitable to prevent upward tin flow during full tinning. Similar to full tinning, adjusting the tin furnace temperature and tinning time can address issues of uneven tinning and gaps. Tin tips or large heads can be avoided by ensuring proper wire twisting.

In conclusion, the above information provides insights into wire tinning machines. It is hoped that through this content, readers gain a deeper understanding of and appreciation for wire tinning machine products.
