Description

Technical Field

[0001] This utility model relates to the field of copper wire processing technology, and in particular to a copper wire surface tin plating processing device. Background Technology

[0002] Tin plating of copper wires refers to covering the surface of copper wires with a layer of metallic tin to isolate them from the air and prevent them from oxidizing. The main functions of tin plating include preventing oxidation, improving conductivity, improving solderability, and enhancing decorative effects.

[0003] Patent publication number CN222411937U discloses a tin plating mold for copper wire, including a tank body with a replenishing tank on one side. Molten tin in the replenishing tank is injected into the tank body via an automatic replenishing mechanism. A cover plate is provided above the tank body, with a connecting post on one side of the cover plate. A connecting hole is provided at the top of the tank body, and the connecting post is inserted into the connecting hole. Although this patent reduces heat loss and improves the heat preservation effect of the tank body by adding a cover plate to the top of the tank body to cover the opening, during the tin plating process, if the molten tin is not stirred, the composition and temperature of the molten tin may be unevenly distributed, easily leading to tin stratification or sedimentation, which in turn affects the density and smoothness of the plating layer, reducing the quality of the tin plating.

[0004] Therefore, a copper wire surface tin plating processing device with stirring function is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, where the composition and temperature of the tin liquid may be unevenly distributed if it is not stirred during the tin plating process, which can easily lead to tin liquid stratification or precipitation, thereby affecting the density and smoothness of the plating layer and reducing the quality of tin plating, this utility model provides a copper wire surface tin plating processing device with stirring function.

[0006] The technical implementation scheme of this utility model is as follows: a copper wire surface tin plating processing device, including a support rod, a tin plating tank, a support frame, a connecting rod, a limiting wheel, a guide pipe, and a first valve. Two support rods are fixedly connected to the bottom left and right sides of the tin plating tank. Two support frames are fixedly connected to the left and right sides of the tin plating tank. The two horizontally aligned support frames are jointly fixedly connected to the connecting rod. Two connecting rods are also fixedly connected inside the tin plating tank. Multiple limiting wheels are rotatably arranged on the connecting rods. A guide pipe is connected and communicated to the right side of the tin plating tank. A first valve is arranged near the tin plating tank on the guide pipe. The device also includes a fixed frame, a motor, and a stirring rod. Two fixed frames are fixedly connected to the lower front side of the tin plating tank. A motor is installed on the fixed frame. Two stirring rods are rotatably arranged inside the tin plating tank. The output shaft of the motor is connected to the stirring rods through a coupling.

[0007] Optionally, it also includes a support plate, a mounting frame, a fan, and an electric heating tube. The support plate is fixedly connected to both the front and rear sides of the left side of the tin plating bath. The top of the two support plates is fixedly connected to the mounting frame. Two fans are installed inside the mounting frame. An electric heating tube is installed inside the mounting frame and is located below the fans.

[0008] Optionally, it also includes a recycling frame, a filter layer, and a second valve. The recycling frame is placed on the right side of the tin plating tank, the filter layer is installed inside the recycling frame, and the second valve is installed on the front side of the recycling frame.

[0009] Optionally, it also includes a collection box, which is placed on the left side of the tin plating bath.

[0010] Optionally, it also includes a partition plate, which is rotatably mounted on the top of the tin plating bath.

[0011] Optionally, it also includes a safety net, with the top of the mounting frame covered by the safety net.

[0012] Compared with the prior art, the present invention provides a copper wire surface tin plating processing device, which has the following beneficial effects: 1. The output shaft of the motor drives the stirring rod to rotate, which stirs the tin liquid inside the tin plating tank, ensuring that the tin liquid composition is uniform and the temperature distribution is consistent, avoiding tin liquid stratification or sedimentation, thereby improving the tin plating quality and forming a denser and smoother plating layer.

[0013] 2. The fan draws outside air into the mounting frame, and the electric heating element heats the air to create hot air that is blown onto the copper wire surface. This quickly removes residual flux and moisture from the copper wire surface and promotes the densification of the tin layer, thereby improving the stability and wear resistance of the tin layer.

[0014] 3. The molten tin is purified by a filter layer inside the recycling box to remove organic pollutants and other substances without affecting the main metal components of the molten tin, thus achieving effective recycling of the molten tin and improving its utilization efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: A copper wire surface tin plating processing apparatus, please refer to Figures 1-5 The system includes a support rod 1, a tin plating tank 2, a support frame 3, a connecting rod 4, a limiting wheel 5, a guide pipe 9, and a first valve 10. A temperature controller is installed on the front side of the tin plating tank 2 to control the temperature of the molten tin inside. Two support rods 1 are fixedly connected to the bottom left and right sides of the tin plating tank 2. Two support frames 3 are fixedly connected to the left and right sides of the tin plating tank 2. The two horizontally aligned support frames 3 are jointly fixedly connected to a connecting rod 4. Two connecting rods 4 are also fixedly connected inside the tin plating tank 2. Three limiting wheels 5 are rotatably installed on the connecting rods 4. A guide pipe 9 is connected and communicates with the right side of the tin plating tank 2. The guide pipe 9 is made of high-temperature resistant material and is close to the tin plating tank. A first valve 10 is installed at position 2. Two fixed brackets 6 are fixedly connected to the lower front side of the tin plating tank 2. A motor 7 is installed on the fixed brackets 6. Two stirring rods 8 are rotatably installed inside the tin plating tank 2. The output shaft of the motor 7 is connected to the stirring rods 8 through a coupling. A collection frame 17 is placed on the left side of the tin plating tank 2. The collection frame 17 is used to collect the material that falls off when the copper wire is led out after tin plating. An isolation plate 18 is rotatably installed on the top of the tin plating tank 2. The isolation plate 18 covers the opening at the top of the tin plating tank 2, thereby reducing the loss of heat in the tank and improving the heat preservation effect of the tin plating tank 2. In addition, it also plays a certain protective role and can prevent the molten tin inside the tin plating tank 2 from splashing out.

[0023] When this device is needed, the copper wire first enters from the right side of the tin plating tank 2, passes above the right limit wheel 5, and then passes below the limit wheel 5 inside the tin plating tank 2, ensuring that the copper wire maintains a straight line during the tin plating process. The tin plating tank 2 contains molten tin. When the copper wire passes through the molten tin, a layer of tin is evenly plated on its surface. After tin plating is completed, the copper wire is led out above the left limit wheel 5. During the tin plating process, the motor 7 is started. The output shaft of the motor 7 rotates to drive the stirring rod 8 to rotate, stirring the molten tin inside the tin plating tank 2 to ensure that the composition of the molten tin is uniform and the temperature distribution is consistent, avoiding tin liquid separation or sedimentation, thereby improving the tin plating quality and forming a denser and smoother coating.

[0024] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 4 The tin plating bath 2 has support plates 11 fixedly connected to both the front and rear sides on the left side. The two support plates 11 are fixedly connected to the top of the mounting frame 1101. Two fans 12 are installed inside the mounting frame 1101. An electric heating tube 13 is installed inside the mounting frame 1101 and is located below the fans 12. The top of the mounting frame 1101 is covered with an isolation net 19. The isolation net 19 filters foreign objects and dust in the outside air to prevent these substances from entering.

[0025] After tinning, the copper wire is led out from above the limiting wheel 5 on the left side of the tinning tank 2 and enters the drying area. At this time, the fan 12 and the electric heating tube 13 are started. The fan 12 runs to draw outside air into the mounting frame 1101. The electric heating tube 13 heats the drawn-in air according to the set temperature, forming hot air and blowing it onto the surface of the copper wire, thereby quickly removing the flux and moisture remaining on the surface of the copper wire, while promoting the crystallization and densification of the tin layer, thereby improving the stability and wear resistance of the tin layer.

[0026] Please see Figure 1 and Figure 5 A recycling box 14 is placed on the right side of the tin plating tank 2. A filter layer 15 is installed inside the recycling box 14, and a second valve 16 is installed on the front side of the recycling box 14.

[0027] After tin plating is completed, the first valve 10 is opened, and the molten tin inside the tin plating tank 2 is introduced into the recovery box 14 through the guide pipe 9. The molten tin is purified by the filter layer 15 inside the recovery box 14 to remove organic pollutants and other substances in the molten tin without affecting the main metal components in the molten tin, thereby realizing the effective recovery of the molten tin and improving the utilization efficiency of the molten tin.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
