Description

Technical Field

[0001] The utility model relates to the technical field of copper wire tinning, in particular to a copper wire tinning device. Background Art

[0002] Due to its excellent performance and low price, copper is widely used in electronic information, lubrication, catalysis, metallurgy and other fields, but copper is very easy to oxidize in the air, and the finer the particle size, the more serious the oxidation; tinned copper wire has been widely used in industrial production and daily life due to its beautiful appearance, high tensile strength, solderability and anti-aging properties. Its coating of inert metal layer can not only significantly improve the oxidation resistance of copper, but also better maintain its conductivity; although tin is not an inert metal and its properties are more active than copper, tin is very stable in the air at room temperature because a dense oxide film will form on the surface of tin to prevent the continued oxidation of tin.

[0003] When the existing tinning device continuously tinns, the uniformity of the tin liquid decreases and the impurity content increases, which leads to a decrease in the quality of tinning. For this reason, we propose a copper wire tinning device. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a copper wire tinning device to solve the technical problems mentioned in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a copper wire tinning device, comprising a tinning device, a feed port is provided on one side of the tinning device, and a discharge port is provided on the other side of the tinning device, guide wheel groups for guiding the copper wire are installed inside and outside the tinning device, and the interior of the tinning device is filled with tin liquid for tinning, and a stirring blade is also provided inside the tinning device to achieve stirring of the tin liquid.

[0006] By adopting the above technical solution, the tin liquid can be stirred in both positive and negative directions, thereby improving the stirring quality, that is, improving the tin plating quality. In addition, the tin liquid can be filtered with high quality to further improve the quality of the tin liquid.

[0007] The utility model is further configured such that a driving motor is installed above the tinning device, and the output end of the driving motor is synchronously connected to a first bevel gear, one side of the first bevel gear is meshedly connected to a second bevel gear, and the bottom end of the second bevel gear is meshedly connected to a third bevel gear installed on the top of the tinning device.

[0008] By adopting the above technical solution, a driving effect is achieved on the driving shaft.

[0009] The utility model is further configured such that the bottom end of the first bevel gear is fixedly connected to a first drive shaft extending into the interior of the tinning device, and part of the stirring blades are installed on the outer wall of the first drive shaft; the bottom end of the third bevel gear is fixedly connected to a second drive shaft slidably sleeved on the outside of the first drive shaft, and part of the stirring blades are installed on the outer wall of the second drive shaft.

[0010] By adopting the above technical solution, the tin liquid can be stirred.

[0011] The utility model is further configured such that a rotating door is installed on the end surface of the first driving shaft, and the rotating door is connected to the outer wall of the first driving shaft through a torsion spring shaft.

[0012] By adopting the above technical solution, the feeding effect of tin liquid is achieved.

[0013] The utility model is further configured such that a first filter chamber is opened on the inner side of the rotating door and inside the stirring blade, and a first filter screen is installed on the end of the first filter chamber, a liquid inlet is opened on the side wall of the first filter chamber, and a second filter chamber connected to the liquid inlet is opened inside the stirring blade, and a second filter screen is installed on the inner wall of the second filter chamber.

[0014] By adopting the above technical solution, the filtering effect of tin liquid is achieved.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model is provided with a driving motor, a bevel gear, a driving shaft and a stirring blade. First, the copper wire is introduced into the tin liquid through the guide wheel group, so as to realize the tinning of the copper wire. After the tinning is completed, the copper wire is led out from the discharge port and cooled to complete the tinning operation of the copper wire. When the tinning is required for a long time, the driving motor is started, and the driving motor drives the first bevel gear to rotate, and the first bevel gear then drives the third bevel gear to rotate through the second bevel gear. At this time, the first driving shaft and the second driving shaft both start to rotate, but the rotation direction is opposite, so the stirring blade can realize the forward and reverse bidirectional stirring of the tin liquid, thereby improving the quality of the tin liquid, that is, improving the tinning quality of the copper wire;

[0017] 2. The utility model provides a rotating door, a filter screen and a filter chamber. During the rotation of the stirring blade, the tin liquid will impact the rotating door to open it. At this time, the tin liquid will enter the first filter chamber and flow out through the first filter screen, thereby achieving a filtering effect on the tin liquid and further improving the quality of the tin liquid. At the same time, the tin liquid entering the first filter chamber will also enter the second filter chamber through the liquid inlet and complete the filtering effect on the tin liquid through the second filter screen. Through the above structure, the filtering amount of the tin liquid per unit time is increased without changing the stirring area, thereby improving the filtering efficiency of the tin liquid.
