Description

Technical Field

[0001] The invention relates to the field of electroplating tools, in particular to an electroplating current reduction protective hanger. Background Art

[0002] The electroplating hanger is a tool used to hang and fix the workpiece to be plated during the electroplating process. The electroplating hanger not only ensures the correct position and posture of the workpiece to be plated in the electroplating tank so that the coating can be evenly deposited on the surface of the workpiece, but also conducts current so that the current is evenly distributed to various parts of the workpiece.

[0003] During the electroplating process, if the current density is too high, the current under the hanger will be too large, thereby generating a large amount of heat. The high temperature environment will accelerate the oxidation and reduction reactions of the plated metal, causing the coating to be charred or burned in this area, which will seriously affect the overall electroplating quality and service life of the workpiece. Summary of the invention

[0004] 1. Technical problems solved In view of the shortcomings of the prior art, the present invention provides an electroplating current reduction protective hanger, which solves the problem that during the electroplating process, if the current density is too high, the current under the hanger will be too large, thereby generating a large amount of heat. The high temperature environment will accelerate the oxidation and reduction reactions of the plated metal, causing the coating to be charred or burned in this area, thereby seriously affecting the overall electroplating quality and service life of the workpiece.

At the same time, rotating the rotating handle during use will drive the mounting block to rotate, and then drive the first thread head to rotate, so that the first thread head can be screwed into the thread groove or unscrewed from the thread groove, thereby realizing the disassembly of the hanging rod.

[0007] Furthermore, one end of each of the plurality of second thread heads is fixedly connected to a fixed block, and surfaces of each of the plurality of fixed blocks are fixedly connected to a rotating handle; Through the above technical solution, rotating the rotating handle will drive the fixed block to rotate and then drive the second thread head fixedly connected to the fixed block to rotate, thereby screwing the second thread head into the thread groove or screwing the second thread head out of the thread groove.

[0012] 3. Beneficial effects The present invention provides a protective hanger for electroplating current reduction, which has the following beneficial effects: 1. The present invention provides an electroplating current reduction protective hanger, which is provided with a current reduction ring at one end of the support rod away from the handle.

[0013] 2. The present invention provides an electroplating current reduction protective hanger, which is provided with a change-of-direction module. When in use, the bolts and nuts are loosened, and the change-of-direction module can slide on the support rod. The position of the change-of-direction module on the support rod is adjusted according to the specifications of the workpiece, and then the workpiece is hung on the hanging rod to ensure that the workpiece is between two adjacent change-of-direction rods after hanging. Then the change-of-direction module is rotated until the change-of-direction rod contacts the corresponding workpiece, and then the change-of-direction module is continued to be rotated. At this time, the movement of the change-of-direction rod will push one end of the workpiece to move, but the end of the workpiece hanging on the hanging rod will not move. Then, when the change-of-direction module rotates, the change-of-direction rod will drive the workpiece to tilt, thereby adjusting the swing direction of the workpiece. During the electroplating process, the workpiece can be tilted and immersed in the electroplating solution, so that the residual air on the surface can be discharged smoothly, which is conducive to the uniform distribution of current on the product surface, thereby improving the electroplating quality of the workpiece.

When in use, the second thread head can be unscrewed and the hanging rod can be installed through the first thread head. Similarly, the first thread head can be unscrewed and the second thread head can be installed inside the fixing ring, thereby changing the number of hanging rods on the fixing ring, and changing the number of hanging rods to change the spacing between the hanging rods on the fixing ring, thereby further changing the current density during the electroplating process of the product, ensuring that the current flows evenly on the surface of the product, and avoiding uneven coating caused by excessive local current.

Four connecting blocks 402 distributed in a circumferential array are fixedly connected to the outside of the mounting tube 401. One end of the four connecting blocks 402 is commonly fixedly connected to a fixing ring 403. Two groups of mounting grooves 404 are opened inside the fixing ring 403. The two groups of mounting grooves 404 are fixedly connected to sealing rings 406. The fixing ring 403 is located inside each mounting groove 404. A threaded groove 405 is opened.

[0020] according to Figure 3 and Figure 7 As shown, one end of multiple first threaded heads 407 is fixedly connected to a mounting block 410, one end of multiple mounting blocks 410 is fixedly connected to a hanging rod 412, and the outside of multiple mounting blocks 410 is fixedly connected to two mirror-image rotating handles 411, the first threaded heads 407, the mounting blocks 410 and the hanging rods 412 are all made of metal copper, the surfaces of the mounting blocks 410 and the rotating handles 411 are coated with insulating paint, the part of the hanging rod 412 close to the mounting block 410 is coated with insulating material, and the surfaces of the mounting blocks 410 and the rotating handles 411 are coated with insulating paint, which can ensure the accuracy of electroplating and avoid unnecessary current loss. At the same time, rotating the rotating handle 411 during use will drive the mounting block 410 to rotate, and then drive the first threaded head 407 to rotate, so that the first threaded head 407 is screwed into the thread groove 405 or unscrewed from the thread groove 405, thereby realizing the disassembly of the hanging rod 412.

[0021] according to Figure 3 , Figure 7 and Figure 8As shown, one end of multiple second thread heads 413 is fixedly connected to a fixed block 414, and the surfaces of multiple fixed blocks 414 are fixedly connected to a rotating handle 415. Rotating the rotating handle 415 will drive the fixed block 414 to rotate and then drive the second thread heads 413 fixedly connected to the fixed block 414 to rotate, so that the second thread heads 413 are screwed into the thread groove 405 or the second thread heads 413 are screwed out of the thread groove 405. A connecting ring 408 is fixedly connected to the surface of one end of the first thread head 407. Multiple connecting rings 408 and the surface of the fixed block 414 are fixedly connected to a sealing ring 409 corresponding to the sealing ring 406, and the sealing ring 409 abuts against the sealing ring 406. The second thread heads 413, the fixed block 414, the connecting ring 408 and the sealing ring 409 are all made of PVC material. When in use, the sealing ring 409 cooperates with the sealing ring 406 to avoid direct contact between the electroplating solution and the thread groove 405 opened in the fixed block 414, thereby reducing unnecessary current loss during the electroplating process.

[0022] according to Figure 4 and Figure 5 As shown, the two direction-changing modules 5 each include a connecting ring 501, one side of the inner wall of the two connecting rings 501 is fixedly connected to a connecting plate 502, two; one end of the connecting plate 502 is fixedly connected to a first limiting edge 503, both sides of the first limiting edge 503 are fixedly connected to guide columns 507, and both sides of the first limiting edge 503 corresponding to the guide columns 507 are slidably connected with bolts 508. When in use, the support rod 1 is clamped by the first limiting edge 503 and the second limiting edge 506 to achieve the positioning of the direction-changing module 5. At the same time, the guide column 507 can ensure that the second limiting edge 506 does not shift during the movement process. One side of the inside of the two connecting rings 501 is fixedly connected to a mounting column 504, and the inside of the two mounting columns 504 is slidable. A sliding block 505 is connected, and one end of the two sliding blocks 505 is fixedly connected to a second limiting edge 506 corresponding to the first limiting edge 503.

One end of the bolt 508 passes through the second limiting edge 506 and is threadedly connected to the nut 509. When in use, the nut 509 and the bolt 508 are tightened. During the tightening process, because the first limiting edge 503 is fixedly connected to the connecting ring 501 through the connecting plate 502, the bolt 508 will drive the second limiting edge 506 to move through the nut 509 during the tightening process, and then the support rod 1 is clamped through the first limiting edge 503 and the second limiting edge 506, thereby realizing the positioning of the change direction module 5.

[0023] according to Figure 4 and Fig. 9As shown, multiple sliding grooves 510 are provided inside the two connecting rings 501, and sliders 511 are slidably connected inside the multiple sliding grooves 510. One end of the multiple sliders 511 is fixedly connected to a fixing column 513, and one end of the multiple fixing columns 513 is fixedly connected to a change-of-direction rod 514. Limiting grooves 512 are provided inside the multiple sliders 511. Positions corresponding to the sliding grooves 510 inside the multiple connecting rings 501 are threadedly connected with top screws 515 corresponding to the limiting grooves 512. The lower end of the top screw 515 extends into the limiting groove 512 and abuts against the inner wall of the limiting groove 512. The top screw 515 is turned by a wrench. 515 causes the top screw 515 to move upward until the lower end of the top screw 515 is out of the limiting groove 512. At this time, the slider 511 and the top screw 515 no longer interfere with each other, and the direction-changing rod 514 can be removed from the connecting ring 501. During installation, the slider 511 at one end of the direction-changing rod 514 is aligned with the sliding groove 510 on the connecting ring 501 and gently pushed in. The top screw 515 is rotated with a wrench until its lower end is tightly against the inner wall of the limiting groove 512. Ensure that the top screw 515 is securely tightened. When in use, the number of direction-changing rods 514 can be adjusted according to the number of hanging rods 412. In this embodiment, by providing a current reduction ring 3 at one end of the support rod 1 away from the handle 2, the current reduction ring 3 can guide the current to be more evenly distributed on the hanger and the workpiece during the actual electroplating process, change the path of the current, effectively disperse the current density, reduce the current intensity in the local area, make the current distribution in the electroplating process more uniform, avoid the plating layer from being burned due to excessive current, thereby improving the uniformity and overall quality of the plating layer; By setting the direction-changing module 5, the bolt 508 and the nut 509 are loosened when in use, and the direction-changing module 5 can slide on the support rod 1. The position of the direction-changing module on the support rod 1 is adjusted according to the specifications of the workpiece, and then the workpiece is hung on the hanging rod 412 to ensure that the workpiece is between two adjacent direction-changing rods 514 after hanging. Then, the direction-changing module 5 is rotated until the direction-changing rod 514 contacts the corresponding workpiece, and then the direction-changing module 5 is continued to be rotated. At this time, the movement of the direction-changing rod 514 will push one end of the workpiece to move, but the end of the workpiece hanging on the hanging rod 412 will not move. Then, when the direction-changing module 5 rotates, the direction-changing rod 514 will drive the workpiece to tilt, thereby adjusting the swing direction of the workpiece. During the electroplating process, the workpiece can be tilted and immersed in the electroplating solution, so that the residual air on the surface can be discharged smoothly, which is conducive to the uniform distribution of current on the product surface, thereby improving the electroplating quality of the workpiece; A first thread head 407 and a second thread head 413 are connected by threads inside the thread groove 405 inside the fixing ring 403. A hanging rod 412 is provided at one end of the first thread head 407 through a mounting block 410. A fixing block 414 is provided at one end of the second thread head 413. When in use, the second thread head 413 can be unscrewed and the hanging rod 412 can be installed through the first thread head 407. Similarly, the first thread head 407 can be unscrewed and the second thread head 413 can be installed inside the fixing ring 403, thereby changing the number of hanging rods 412 on the fixing ring 403. By changing the number of hanging rods 412, the spacing between the hanging rods 412 on the fixing ring 403 can be changed, thereby further changing the current density during the product electroplating process, ensuring that the current flows evenly on the product surface, and avoiding uneven coating caused by excessive local current.

[0024] Working principle: First, determine the required number of hanging rods 412 according to the number of products to be electroplated, install the hanging rods 412 in the thread groove 405 inside the fixing ring 403 through the first thread head 407, install the second thread head 413 in the remaining thread groove 405, determine the required number of changing rods 514 according to the number of installed hanging rods 412, use a wrench to turn the top screw 515 to move the top screw 515 upward until its lower end is out of the limit groove 512. At this time, there is no interference between the slider 511 and the top screw 515, and the redundant direction-changing rod 514 can be removed from the connecting ring 501, and then the bolt 508 and the nut 509 are loosened. At this time, the direction-changing module 5 can slide on the support rod 1. According to the specifications of the product, the position of the direction-changing module 5 on the support rod 1 is adjusted. After the adjustment is completed, the bolt 508 and the nut 509 are tightened again, and the support rod 1 is clamped by the first limiting edge 503 and the second limiting edge 506 to realize the positioning of the direction-changing module 5. Then, the products to be electroplated are hung on the hanging rod 412 to ensure that each product is between two adjacent The bolt 508 and the nut 509 are loosened again to allow the direction-changing module 5 to rotate. The direction-changing module 5 is rotated until the direction-changing rod 514 contacts the corresponding workpiece. The direction-changing module 5 is continued to be rotated. At this time, the movement of the direction-changing rod 514 will push one end of the workpiece to move, but the end of the workpiece hanging on the hanging rod 412 will not move. Therefore, when the direction-changing module 5 rotates, the workpiece will be tilted through the direction-changing rod 514, thereby adjusting the swing direction of the workpiece. After the adjustment is completed, the bolt 508 and the nut 509 are tightened again to fix the position of the direction-changing module 5, and electroplating can begin.
