Description

Technical Field

[0001] This utility model relates to the field of copper busbar passivation technology, and in particular to a copper busbar surface corrosion resistant passivation device. Background Technology

[0002] Copper busbars are long, conductive metal materials made of high-purity copper. They are commonly used in power equipment, electrical control cabinets, switchgear, and other high-current transmission systems that require high conductivity. During the processing of copper busbars, passivation liquid is used to passivate them.

[0003] An existing copper plating plate passivation device (publication number: CN221837098U) has at least the following drawbacks: Although the above device cleans the workpiece with a cleaning plate and then passesivates the workpiece by immersing it in passivation solution, both the cleaning and immersion are carried out in the passivation tank. The impurities cleaned out mix with the passivation solution in the passivation tank, which increases the filtration burden of the passivation solution on the device and increases the loss of passivation solution, resulting in poor passivation effect of the device. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a copper busbar surface corrosion-resistant passivation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] As a further embodiment of this utility model, an air inlet hole is provided on one side of the inner wall of the processing tank, and a fixed shell is fixed on one side of the processing box.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This passivation device, through the design of the passivation structure, uses an electric push rod to lower the placement box into the cleaning tank, allowing the cleaning solution to immerse and clean the copper busbar. An ultrasonic generator then uses high-frequency vibrations in the cleaning solution to further clean the copper busbar. After cleaning, the operator activates the electric push rod to remove the placement box from the cleaning tank. The screw rotates, moving the connecting plate and placing the placement box into the passivation tank, where the passivation solution further immerses and passivates the copper busbar. This method avoids excessive impurities mixing with the passivation solution during passivation, reducing passivation solution loss and filtration burden, and improving the passivation effect of the copper busbar.

[0023] like Figures 1-5As shown, a copper busbar surface corrosion-resistant passivation device includes a treatment box 1. The top surface of the treatment box 1 is provided with a cleaning groove 2, a treatment groove 3, and a passivation groove 4. The top surface of the treatment box 1 is provided with a passivation structure, which includes a mounting bracket 201 fixed to the top surface of the treatment box 1. The top surface of the mounting bracket 201 is provided with a movable hole 202. A lead screw 203 is rotatably arranged inside the movable hole 202. A connecting plate 204 is slidably arranged inside the movable hole 202. The connecting plate 204 is threadedly connected to the lead screw 203. An electric push rod 205 is fixed to the top surface of the connecting plate 204. The telescopic end of the electric push rod 205 passes through the interior of the connecting plate 204 and is fixed with a placement box 206. The placement box 206 is slidably inserted into the interior of the cleaning groove 2.

[0024] In this embodiment, a motor is fixed to one side of the mounting bracket 201. The output end of the motor passes through one side of the mounting bracket 201 and is fixed to one end of the lead screw 203. The placement box 206 corresponds to the shape of the processing tank 3 and the passivation tank 4. The bottom surface and four sides of the placement box 206 are hollow structures. An ultrasonic generator 207 is fixed to one side of the processing box 1. The ultrasonic probe of the ultrasonic generator 207 passes through one side of the processing box 1 and extends into the interior of the cleaning tank 2. The ultrasonic generator 207 is existing technology. Through the passivation structure, the operator puts multiple copper busbars that need to be passivated into the placement box 206. Then, the electric push rod 205 is activated to drive the placement box 206 down into the cleaning tank 2, so that the cleaning solution immerses the copper busbars. Without cleaning, the ultrasonic generator 207 is then activated. The ultrasonic generator 207 generates high-frequency vibrations in the cleaning solution to clean the copper busbar, reducing surface impurities during passivation. After cleaning, the operator activates the electric push rod 205 to retract, causing the placement box 206 to leave the cleaning tank 2. Then, the motor is activated to rotate the lead screw 203, which in turn moves the connecting plate 204, thus moving the placement box 206 above the passivation tank 4. The electric push rod 205 extends, placing the placement box 206 into the passivation tank 4, allowing the passivation solution to soak and passivate the copper busbar. This method avoids excessive impurities mixing with the passivation solution during passivation, reducing passivation solution loss and filtration burden, and improving the passivation effect of the copper busbar.

[0025] In this embodiment, an air inlet 303 is provided on one side of the inner wall of the processing tank 3, and a fixing shell 301 is fixed on one side of the processing box 1. The fixing shell 301 corresponds to the position of the air inlet 303. An air intake fan 302 is fixed inside the fixing shell 301. After the copper busbar passivation is completed, the operator uses the electric push rod 205 and the lead screw 203 to lift the placement box 206 out of the passivation tank 4 and put it into the processing tank 3 for draining. Then, the air intake fan 302 is started to dry the copper busbar in the placement box 206.

[0026] In this embodiment, a first pump body 401 is fixedly connected to the other side of the processing box 1, a filter box 402 is fixedly connected to one side of the first pump body 401, a second pump body 403 is fixedly connected to the top surface of the filter box 402, the second pump body 403 is fixedly connected to the processing box 1, and a filter plate 404 is slidably inserted into the top surface of the filter box 402. The filter plate 404 is the prior art. When the passivation liquid is mixed with impurities after multiple uses, the operator starts the first pump body 401 to pump the passivation liquid into the filter box 402, the filter plate 404 filters the passivation liquid, and the second pump body 403 sends the filtered passivation liquid into the passivation tank 4.

[0027] In this embodiment, a cover plate 5 is slidably inserted inside the placement box 206. A fixing frame 501 is fixed to the inner wall of the placement box 206, with the top surface of the fixing frame 501 fitting against the bottom surface of the cover plate 5. A rotating block 502 is rotatably installed on one side of the inner wall of the placement box 206, and a locking shaft 503 is slidably inserted on one side of the rotating block 502. An installation notch 504 is provided on one side of the cover plate 5. After the copper busbar is placed into the placement box 206, the operator then places the cover plate 5 into the placement box 206 to prevent the copper busbar from floating up during immersion. During the placement of the cover plate 5, the rotating block 502 and the locking shaft 503 pass through the installation notch 504. The operator rotates the rotating block 502 to make the locking shaft 503 lie horizontally and slides the locking shaft 503 to lock the position of the cover plate 5, preventing the cover plate 5 from floating up during immersion.

[0028] In this embodiment, a heating element 6 is fixed to the bottom surface of the passivation tank 4, and a temperature sensor 601 is fixed to one side of the inner wall of the passivation tank 4. The passivation liquid can be heated to a suitable temperature by the heating element 6 to improve the passivation effect on the copper busbar.

[0029] Working Principle: In use, the operator places multiple copper busbars requiring passivation into the placement box 206. Then, the electric actuator 205 lowers the placement box 206 into the cleaning tank 2, immersing the copper busbars in the cleaning solution. Next, the ultrasonic generator 207 is activated, generating high-frequency vibrations in the cleaning solution to clean the copper busbars and reduce surface impurities during passivation. After cleaning, the operator retracts the electric actuator 205, removing the placement box 206 from the cleaning tank 2. Then, the motor drives the lead screw 203 to rotate, moving the connecting plate 204 and thus moving the placement box 206 above the passivation tank 4. The electric actuator 205 extends, placing the placement box 206 into the passivation tank 4, allowing the passivation solution to soak and passivate the copper busbars. Once passivation is complete, the operator uses the electric actuator 205 and lead screw 203 to lower the placement box 206 back into the passivation tank 4. 6. The copper busbars are removed from the passivation tank 4 and placed into the treatment tank 3 for draining. Then, the inlet fan 302 is started to dry the copper busbars in the placement box 206. When the passivation solution becomes contaminated with impurities after multiple uses, the operator starts the first pump 401 to pump the passivation solution into the filter box 402. The filter plate 404 filters the passivation solution. The second pump 403 sends the filtered passivation solution into the passivation tank 4. After the copper busbars are placed into the placement box 206, the operator puts the cover plate 5 into the placement box 206 to prevent the copper busbars from floating up during immersion. During the placement of the cover plate 5, the rotating block 502 and the locking shaft 503 pass through the installation notch 504. The operator rotates the rotating block 502 to make the locking shaft 503 lie horizontally and slides the locking shaft 503 to lock the position of the cover plate 5 to prevent the cover plate 5 from floating up during immersion. The heating plate 6 can heat the passivation solution to a suitable temperature to improve the passivation effect on the copper busbars.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
