Description

Technical Field

[0001] This utility model relates to the field of tin plating technology, specifically a tin plating tank for copper wire processing. Background Technology

[0002] Tin-plated copper wire refers to copper wire with a thin layer of tin plated on its surface. It is processed using a tin-plating bath. Refer to announcement number CN221895087U, which describes a tin-plating bath for copper wire processing. This bath includes a tank body with pressure rollers rotatably mounted on the front and rear inner walls. A clamping mechanism is located on the left side of the tank body, and a cleaning mechanism is located to the left of the clamping mechanism. The clamping mechanism includes a clamping part and an adjusting part, used to clamp the copper wire and prevent it from loosening. The cleaning mechanism includes a cleaning part and a connecting part, used to clean debris from the outer wall of the copper wire. When the copper wire is passed through the upper and lower rollers and pulled, the copper wire drives the upper and lower rollers to rotate.

[0003] The aforementioned device prevents the tin-plated layer from being tinned inside the copper wire during tin plating, thus ensuring the quality of the tin plating. However, it lacks an ultrasonic auxiliary structure, which affects the tin plating effect. Furthermore, the lack of an auxiliary moisture evaporation structure in the later stage results in the tin liquid not being completely solidified during transportation, leading to deformation of the tin plating layer during roller conveying. Utility Model Content

[0004] The purpose of this invention is to provide a tin plating bath for copper wire processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tin plating bath for copper wire processing includes an insulated shell, wherein an inner liner is embedded and connected inside the insulated shell;

[0007] A base is fixedly connected to the lower surface of the insulation shell, and an ultrasonic transmitter is placed on the upper surface of the base. A resistance wire heating tube is nested inside the insulation shell on the outer surface of the inner liner. A third guide roller is rotatably connected inside the inner liner.

The cleaning mechanism includes a cleaning roller and a gear. There are two cleaning rollers, which are rotatably connected to the inner surface of the second mounting seats. The gears are fixedly connected to the outer surface of the second mounting seats, and the two gears are meshed together.

[0008] Furthermore, the outer surface of the base is fixedly connected with four support legs, and the ends of the support legs are flat plate structures.

[0009] Furthermore, an ultrasonic transducer is fixedly connected to the lower surface of the inner liner, and the ultrasonic transmitter and the ultrasonic transducer are electrically connected.

[0010] Furthermore, a pipe clamp is fixedly connected to the outer surface of the resistance wire heating tube, and the resistance wire heating tube is fixedly connected to the inner liner through the pipe clamp.

[0011] Furthermore, a controller is fixedly connected to the outer surface of the heat-insulating shell, and the controller is electrically connected to the resistance wire heating tube.

[0012] Furthermore, the upper surface of the heat-insulating shell is fixedly connected to two first mounting seats, the inner surface of the first mounting seats is rotatably connected to a second guide roller, the inner surface of the second mounting seats is rotatably connected to a first guide roller, and the outer surface of the second mounting seats is fixedly connected to a motor, the output end of the motor being fixedly connected to one of the cleaning rollers.

[0013] Furthermore, the inner surface of the inner liner is provided with a U-shaped groove, the upper end of the U-shaped groove is fixedly connected to a screen, and the upper surface of the screen is fixedly connected to an air intake fan.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The ultrasonic transmitter can generate ultrasonic vibration through the ultrasonic transducer, which causes the molten tin in the inner tank to generate high-frequency micro-vibrations, further improving the quality and uniformity of copper wire tin plating. The controller can precisely control the heating power and temperature of the resistance wire heating tube, thereby achieving precise control of the temperature of the molten tin in the inner tank and ensuring the tin plating effect.

[0016] 2. After the copper wire passes through the molten tin, outside air passes through the U-shaped groove under the action of the air intake fan. The air is kept clean by the filtration of the screen, and this airflow is heated by the inner tank, which can dry the molten tin on the outer surface of the copper wire, accelerate the evaporation of moisture in the molten tin and make the tin layer solidify quickly, thereby improving the hardness and adhesion of the tin-plated layer, further improving the performance of the copper wire after tin plating, and preventing it from deforming during transportation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Please see Figure 1-4 In this embodiment of the present invention, a tin plating bath for copper wire processing includes a heat-insulating shell 1, and an inner liner 4 is embedded and connected inside the heat-insulating shell 1.

[0024] A base 101 is fixedly connected to the lower surface of the heat-insulating shell 1. An ultrasonic transmitter 2 is placed on the upper surface of the base 101. A resistance wire heating tube 3 is nested inside the heat-insulating shell 1 on the outer surface of the inner liner 4. A third guide roller 502 is rotatably connected inside the inner liner 4. Two second mounting seats 402 are fixedly connected to the upper surface of the heat-insulating shell 1. A cleaning mechanism 6 is provided on the inner surface of the second mounting seat 402. The cleaning mechanism 6 includes a cleaning roller 602 and a gear 603. There are two cleaning rollers 602 and they are rotatably connected to the inner surface of the second mounting seat 402. The gear 603 is fixedly connected to the outer surface of the second mounting seat 402, and the two gears 603 are meshed together.

[0025] Specifically, when using it, the winding path of the copper wire is as follows: Figure 3 As shown, the molten tin is located inside the inner liner 4. The copper wire passes around the third guide roller 502 for tin plating. The resistance wire heating tube 3, together with the heat preservation shell 1, keeps the inner liner 4 warm to prevent the molten tin from cooling. The cleaning mechanism 6 cleans the copper wire through two cleaning rollers 602 to reduce the amount of debris adhering to the surface of the copper wire and improve the tin plating effect of the copper wire.

[0026] Example 1

[0027] like Figure 1-4As shown, four support legs 102 are fixedly connected to the outer surface of the base 101, and the ends of the support legs 102 are flat plate structures. An ultrasonic transducer 201 is fixedly connected to the lower surface of the inner liner 4. The ultrasonic transmitter 2 and the ultrasonic transducer 201 are electrically connected.

[0028] In this embodiment, the ultrasonic transmitter 2 can generate ultrasonic vibration through the ultrasonic transducer 201, causing the molten tin in the inner tank 4 to generate high-frequency micro-vibrations, further improving the quality and uniformity of copper wire tin plating. At the same time, the four support legs 102 can stably support the entire tin plating tank device.

[0029] like Figure 2-4 As shown, a pipe clamp 301 is fixedly connected to the outer surface of the resistance wire heating tube 3. The resistance wire heating tube 3 is fixedly connected to the inner liner 4 through the pipe clamp 301. A controller 302 is fixedly connected to the outer surface of the heat insulation shell 1. The controller 302 is electrically connected to the resistance wire heating tube 3.

[0030] In this embodiment, the controller 302 can precisely control the heating power and temperature of the resistance wire heating tube 3, thereby achieving precise control of the temperature of the molten tin in the inner liner 4. The resistance wire heating tube 3 is firmly fixed to the inner liner 4 by the tube clamp 301, ensuring that the heating tube is stable and reliable during operation and effectively preventing problems such as uneven heating caused by the loosening of the heating tube.

[0031] Example 2

[0032] Based on Example 1, in order to overcome the problem of inconvenience in cooling the copper wire in Example 1.

[0033] like Figure 1-4 As shown, two first mounting seats 401 are fixedly connected to the upper surface of the heat insulation shell 1. A second guide roller 501 is rotatably connected to the inner surface of the first mounting seat 401. A first guide roller 5 is rotatably connected to the inner surface of the second mounting seat 402. A motor 601 is fixedly connected to the outer surface of the second mounting seat 402. The output end of the motor 601 is fixedly connected to one of the cleaning rollers 602.

[0034] In this embodiment, the motor 601 drives one of the cleaning rollers 602 to rotate, and then the gears 603 on the two cleaning rollers 602 mesh, causing the other cleaning roller 602 to rotate as well, thereby cleaning the copper wire. At the same time, the second guide roller 501 and the first guide roller 5 can provide good guidance for the copper wire, allowing the copper wire to run smoothly in the tin plating bath, avoiding the copper wire from getting tangled or deviating from the normal path, and further improving the tin plating efficiency and quality.

[0035] like Figure 3As shown, a U-shaped groove 403 is provided on the inner surface of the inner liner 4, and a screen 404 is fixedly connected to the upper end of the U-shaped groove 403. An air intake fan 405 is fixedly connected to the upper surface of the screen 404.

[0036] In this embodiment, after the copper wire passes through the molten tin, the outside air passes through the U-shaped groove 403 under the action of the intake fan 405. The air is kept clean by the filtration of the screen 404, and the airflow is heated by the inner liner 4. This can dry the molten tin on the outer surface of the copper wire, so that the tin layer can be quickly solidified, thereby improving the hardness and adhesion of the tin-plated layer and further improving the performance of the copper wire after tin plating.
