Description

Technical Field

[0001] This utility model relates to the field of metal polishing technology, and in particular to a device for polishing the surface of electroplated terminals. Background Technology

[0002] Polishing equipment for electroplated terminals plays a crucial role in improving the surface quality of electroplated terminals and ensuring electrical connection performance and appearance quality. As the electrical industry's requirements for terminal quality continue to increase, polishing technology is gradually developing towards higher precision, automation, and intelligence, significantly improving processing efficiency and accuracy. Common defects on the surface of electroplated terminals, such as roughness and oxide layers, affect the contact resistance and corrosion resistance of the terminals, thus requiring improvement through polishing processes. Modern polishing equipment not only emphasizes precision and consistency but also processing efficiency, adaptability, and environmental friendliness, mainly including automated polishing equipment, ultrasonic polishing equipment, and laser polishing equipment. In the future, with the continuous advancement of intelligent manufacturing technology, polishing equipment will develop towards higher precision, higher efficiency, and greater environmental friendliness, driving further technological progress and industrial upgrading in the electrical connection industry.

[0003] A search revealed an existing patent (publication number: CN210413991U) that discloses a polishing device for electroplated terminal surfaces. The device is characterized by: a frame with a mounting plate on top, on which two sets of polishing wheels are mounted; each polishing wheel includes a left polishing wheel and a right polishing wheel, with the left polishing wheel positioned to the left of the right polishing wheel, near the rear of the mounting plate, and the right polishing wheel near the front of the mounting plate; a horizontal and a vertical spacing is provided between the left and right polishing wheels; a left stop wheel is rotatably mounted on the left side of the bottom surface of the mounting plate, and a right stop wheel is mounted on the right side of the bottom surface of the mounting plate, with the left stop wheel positioned to the left front of the left polishing wheel and the right stop wheel positioned to the right rear of the right polishing wheel. This invention improves polishing efficiency and quality while reducing the labor intensity of operators.

[0004] However, in actual use, the above-mentioned solution generates metal particles after grinding the electroplated terminals. The equipment cannot process these particles, which, if they enter the equipment, accelerate the wear of mechanical parts, shorten its lifespan, and increase maintenance costs. Furthermore, particles remaining on the terminal surface can cause scratches, stains, or irregular marks, affecting appearance and electrical contact performance, and even reducing processing efficiency, leading to longer production cycles. Untreated metal particles can also pollute the production environment, increasing cleaning costs and posing a threat to worker health. They may also affect the effectiveness of subsequent electroplating or surface treatment processes.

[0005] Therefore, this utility model provides a device for polishing the surface of electroplated terminals. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing equipment cannot process the generated metal particles, and that metal particles entering the equipment will accelerate the wear of mechanical parts, shorten the service life of the equipment, and increase maintenance costs. Therefore, this invention proposes a polishing device for the surface of electroplated terminals.

[0020] Compared with the prior art, the present invention provides a polishing device for the surface of electroplated terminals, which has the following beneficial effects:

[0021] 1.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Reference Figure 1-6 A polishing device for electroplated terminal surfaces, comprising a first support frame 1, and further comprising:

[0034] The second support frame 11 is fixedly installed inside one side of the first support frame 1, and the second support frame 11 is supported and fixed by the first support frame 1;

[0035] The grinding assembly is located inside the second support frame 11, and the second support frame 11 supports the grinding assembly.

[0036] The operating table 2 is fixedly installed in the middle section of the inner side of the first support frame 1, and the operating table 2 is supported and fixed by the first support frame 1;

[0037] The dust collection component is located at the bottom of the operating table 2, and the operating table 2 supports the dust collection component.

[0038] The dust removal component is located outside the filter end of the dust collection component and is used to clean the metal particles filtered out by the filter end of the filter component.

[0039] The gas recirculation component is located outside the exhaust end of the dust collection component, and its outlet end is located at the top of the grinding end of the grinding component. The gas generated after filtration by the dust collection component is transported to the top of the grinding end of the grinding component by the gas recirculation component, and blows the metal particles generated during the grinding of the electroplated terminal into the interior of the dust collection component.

[0040] The grinding assembly includes a first motor 12 fixedly connected to the inner middle section of the second support frame 11, a guide wheel 14 symmetrically arranged and rotatably connected to the second support frame 11 on the side closer to the first support frame 11, a tension wheel 15 slidably connected to the outer wall of the second support frame 11 on the side away from the first support frame 11, and a fastening bolt 17 bolted to the inner side of the moving end of the tension wheel 15. The tension wheel 15 slides on the slide rod of the second support frame 11 via a sliding bracket located on the outer side of the tension wheel 15. The rotation of the fastening bolt 17 increases the distance between the sliding bracket and the second support frame 11. The friction between the sliding rods fixes the position of the tension wheel 15. A pulley 13 is provided at the output end of the first motor 12. The driven wheel in the pulley 13 is rotatably connected to the outer wall of the second support frame 11. The driven wheel in the pulley 13 is fixedly connected to the bottom guide wheel 14. The driving wheel in the pulley 13 is fixedly connected to the output end of the first motor 12. The first motor 12 drives the bottom guide wheel 14 to rotate through the pulley 13. A polishing belt 16 is rotatably connected to the outside of the guide wheel 14. The polishing belt 16 is rotatably connected to the tension wheel 15. The guide wheel 14 and the tension wheel 15 cooperate to support the polishing belt 16. The rotation of the bottom guide wheel 14 drives the polishing belt 16 to rotate, thereby polishing the electroplated terminal.

[0041] The dust collection assembly includes a filter box 21 fixedly connected to the bottom of the operating table 2. The operating table 2 supports and fixes the filter box 21. A filter screen 22 is fixedly connected to the outer wall of the filter box 21 on the side away from the second support frame 11. The filter screen 22 is fixedly fixed by the filter box 21. Evenly distributed exhaust fans 3 are fixedly connected to the outside of the filter screen 22. Multiple exhaust fans 3 are supported and fixed by the filter screen 22. The exhaust fans 3 draw gas from inside the filter box 21 through the filter screen 22. During the process, metal particles in the air are filtered by the filter screen 22. At the same time, the gap between the filter box 21 and the grinding belt 16 replenishes air into the filter box 21 during the metal particle extraction process, so that the metal particles move into the filter box 21 and do not leak out through the gap.

[0042] The dust removal assembly includes a second motor 23 fixedly connected to one side of the outer wall of the filter box 21. The filter box 21 supports and fixes the second motor 23, and also provides stress points for the second motor 23. A cleaning impeller 24 is fixedly connected to the output end of the second motor 23. The second motor 23 supports and fixes the cleaning impeller 24, and drives the cleaning impeller 24 to rotate. The cleaning impeller 24 is rotatably connected to the outer wall of the filter screen 22 near the second support frame 11. By rotating on the outside of the filter surface of the filter screen 22, the cleaning impeller 24 cleans the metal particles filtered down the filter surface. A discharge pipe 25 is fixedly connected to the other side of the outer wall of the filter box 21. The discharge pipe 25 is connected to the inside of the filter box 21. While the cleaning impeller 24 cleans the filter surface, it pushes the cleaned metal particles toward the discharge pipe 25, and the metal particles are collected by a collection device set outside the discharge pipe 25.

[0043] The gas recirculation assembly includes a sealing chamber 31 fixedly connected to the outer wall of the filter screen 22. The filter screen 22 supports and fixes the sealing chamber 31. The sealing chamber 31 is sleeved on the outside of the exhaust fan 3 and seals the exhaust fan 3. Delivery pipes 32 are fixedly connected to both sides of the outer wall of the sealing chamber 31. Evenly distributed nozzles 33 are fixedly connected to the outer wall of the delivery pipes 32 near the second support frame 11. The gas delivered by the exhaust fan 3 through the sealing chamber 31 is delivered into the nozzles 33 through the delivery pipes 32 and then delivered out through the nozzles 33.

[0044] The operating table 2 is located near the grinding belt 16 and has a dust inlet. The metal particles generated during grinding are conveyed through the dust inlet. The metal particles generated during grinding are blown downward by the gas blown out by the nozzle 33. At the same time, the metal particles are extracted by the exhaust fan 3 and enter the filter box 21.

[0045] Specifically, when this electroplated terminal surface polishing device is working:

[0046] First, rotate the fastening bolt 17 to make the sliding bracket on the outside of the tension wheel 15 slide on the slide rod of the second support frame 11 to adjust the position of the tension wheel 15 and adjust the tension of the grinding belt 16. Then, the first motor 12 drives the bottom guide wheel 14 to rotate through the pulley 13, and the guide wheel 14 drives the grinding belt 16 to rotate synchronously.

[0047] The electroplated terminals are placed on top of the workbench 2 manually, and the terminals are polished by the polishing belt 16.

[0048] The exhaust fan 3 draws air from inside the filter box 21 through the filter screen 22, thereby absorbing the metal particles generated during the grinding process. Then, the gas carrying the metal particles moves to one side of the filter screen 22 and filters the metal particles in the air through the filter screen 22.

[0049] The second motor 23 drives the cleaning impeller 24 to rotate on the outside of the filter surface of the filter screen 22, thereby cleaning the metal particles filtered by the filter screen 22 and pushing the metal particles to the discharge pipe 25. Then, the metal particles are transported out through the discharge pipe 25 and collected by an external collection device.

[0050] The air discharged by the exhaust fan 3 is collected through the sealed chamber 31, and then transported into the nozzle 33 through the delivery pipe 32. It is then sprayed out through the nozzle 33 and blown from the top of the grinding position to the bottom of the grinding position, thereby improving the collection rate of metal particles.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
