Description

Technical Field

[0001] The present invention relates to the technical field of electroplating, and in particular to a precious metal electroplating device. Background Art

[0002] At present, there are three mainstream methods of electroplating precious metals in the industry: spot plating, brush plating and immersion plating, which are especially used in the field of high-precision continuous electroplating wire terminal equipment. However, it is found in production that these three types of electroplating also have their own advantages and disadvantages.

[0003] Traditional spot plating has high precision, but each product requires a corresponding mold wheel, which requires a large amount of chemicals and has high investment costs; traditional brush-mounted brush plating has low investment in chemicals, but the electroplating efficiency is low, which limits the production capacity of the electroplating production line; traditional immersion plating has difficulty in controlling electroplating precision and requires more chemicals.

[0004] This is a major difficulty in the industry. These three traditional electroplating methods can no longer meet the market's demand for small-batch, diversified, and high-precision product production, so a new electroplating method is urgently needed. Summary of the invention

[0007] The precious metal electroplating device of the present invention stores liquid medicine in an anode tank, and then allows the part of the product to be treated to contact the liquid medicine through a product conveying mechanism. At this time, both the anode component and the cathode component are connected to the product, which facilitates the electroplating of the part of the product to be treated. On the one hand, only the part of the product to be treated can be electroplated with high electroplating accuracy. On the other hand, only the part of the product to be treated is in contact with the liquid medicine, which reduces the waste of the liquid medicine and can greatly reduce costs.

The anode adjusting mechanism is adapted to adjust the position of the product conveying mechanism in the Y-axis and Z-axis directions.

[0015] Further, through slots are provided at both ends of the anode box along the product conveying direction. The through slots communicate with the working slot, and the bottom surface of the through slot is lower than the top surface of the working slot.

[0016] Further, a mother groove is provided on the machine frame. A delivery pump is connected to the mother groove. The delivery pump is connected to the liquid inlet pipe. A heater is provided on the mother groove.

[0032] The present invention discloses a noble metal electroplating device.

[0033] Referring to Figures 1 to 7 , a noble metal electroplating device includes a frame 1. An anode adjusting mechanism and a cathode adjusting mechanism 3 are provided on the frame 1. The movable end of the anode adjusting mechanism is connected with an anode box 4, and an anode tank 41 for storing a liquid medicine is formed on the anode box 4. The movable end of the cathode adjusting mechanism 3 is connected with a product conveying mechanism 6. The product conveying mechanism 6 is adapted to convey a product and make the part to be processed of the product contact with the liquid medicine. An anode member and a cathode member 65 are also provided on the frame 1. The anode member contacts with the liquid medicine in the anode tank 41, and the cathode member 65 is electrically connected with the product.

[0034] During operation, the liquid medicine is stored in the anode tank 41, and then the part to be processed of the product is made to contact with the liquid medicine through the product conveying mechanism 6. At this time, both the anode member and the cathode member 65 are electrically connected with the product, which is convenient for electroplating the part to be processed of the product. On the one hand, it can electroplate only the part to be processed of the product with high electroplating accuracy. On the other hand, only the part to be processed of the product contacts with the liquid medicine, resulting in less waste of the liquid medicine and significantly reducing the cost.

[0035] There are two sets of anode adjustment mechanisms, which are arranged at both ends of the frame 1 along the X-axis direction. The anode adjustment mechanism includes an adjustment rod 21, an adjustment block 22, a screw rod 23 and a threaded block. The adjustment rod 21 is fixedly connected to the frame 1 along the Y-axis direction. The adjustment block 22 slides along the Y-axis direction on the adjustment rod 21. There are two adjustment rods 21 to enable the adjustment block 22 to slide stably. A locking nut 25 is threadedly connected to the adjustment rod 21. There are at least two locking nuts 25, which respectively abut against both ends of the adjustment block 22 along the Y-axis direction to relatively fix the adjustment block 22. The screw rod 23 is arranged along the Z-axis direction and is rotatably connected to the adjustment block 22. A bottom of the adjustment block 22 is further fixedly connected with an adjustment bracket 26. The threaded block 24 slides along the Z-axis direction on the adjustment bracket 26, and the threaded block 24 is threadedly connected to the screw rod 23. Rotating the screw rod 23 can drive the threaded block 24 to move along the Z-axis direction. The threaded block 24 is fixedly connected to the anode box 4 to adjust the position of the anode box 4 along the Y-axis and Z-axis directions.

[0036] The anode adjustment mechanism is adapted to adjust the position of the product conveying mechanism 6 along the Y-axis and Z-axis directions. The structure of the cathode adjustment mechanism 3 is the same as that of the anode adjustment mechanism, which will not be elaborated here.

[0037] Specifically, a mother tank 5 is installed on the frame 1. The mother tank 5 stores the liquid medicine. A heater 51 is installed on the mother tank 5 for heating the liquid medicine. The heater 51 can adopt a submersible electric heater. A delivery pump 52 is also connected to the mother tank 5. The output end of the delivery pump 52 is connected with a liquid inlet pipe 53. The anode tank 41 includes a storage tank 411 and a working tank 413. The storage tank 411 is connected with the liquid inlet pipe 53. A connection hole 412 is communicated between the storage tank 411 and the working tank 413. The storage tank 411 is arranged below the working tank 413 so that the liquid medicine in the storage tank 411 can overflow into the working tank 413 through the connection hole 412. The cross-sectional shape of the connection hole 412 can be circular or square, as long as the liquid medicine can pass through.

[0038] The anode member includes a conductive plate 27 and an anode plate 28. The conductive plate 27 is fixedly connected to the anode box 4 and is connected to the anode plate 28. The anode plate 28 is horizontally arranged and passes through the working tank 413. The anode plate 28 is located above the connection hole 412. Electroplating holes 281 are provided on the anode plate 28. At least part of the vertical projection of the electroplating holes 281 coincides with the connection hole 412 so that the liquid medicine overflowing from the connection hole 412 needs to pass through the anode plate 28. The anode plate 28 can adopt a platinum anode titanium mesh. The cross-section of the electroplating holes 281 can be diamond-shaped, circular or other shapes, as long as the liquid medicine can pass through.

[0039] Specifically, the product conveying mechanism 6 includes a conveying frame 61, a stabilizing component 62 and a power component. The conveying frame 61 is fixedly connected to the movable end of the cathode adjusting mechanism 3. A pressing rod 63 slides along the X-axis direction on the conveying frame 61, and the conveying frame 61 locks the pressing rod 63 by bolts. A pressing wheel 64 is rotatably connected to the pressing rod 63. An auxiliary tooling 66 is provided on the conveying frame 61. The auxiliary tooling 66 is pressed below the pressing wheel 64 and is suitable for installing the product. The stabilizing component 62 is suitable for conveying the auxiliary tooling 66 so that the part of the product to be processed contacts the liquid medicine. The cathode part 65 is fixedly connected to the conveying frame 61. When the auxiliary tooling 66 is conveyed, it passes over the cathode part 65, so that the conveying tooling 66 is always in contact with the cathode part 65 to make the cathode part 65 conduct with the product. There are at least two groups of cathode parts 65 arranged along the X-axis direction to ensure that when the product contacts the liquid medicine, there is always a cathode part 65 in contact with the auxiliary tooling 66, thereby ensuring the conduction between the cathode part 65 and the product.

[0040] More specifically, the stabilizing component 62 includes a moving rod 621, a support rod 622 and a stabilizing wheel 623. The moving rod 621 is slidably connected to the frame 1 along the Z-axis direction, and the frame 1 can lock the moving rod 621 by bolts. The support rod 622 is horizontally arranged and fixedly connected to the moving rod 621. The stabilizing wheel 623 is rotatably connected to the support rod 622. Positioning pins 6231 are evenly arranged in a circumferential array on the stabilizing wheel 623, and positioning grooves 661 for inserting the positioning pins 6231 are provided on the auxiliary tooling 66. When the auxiliary tooling 66 moves, the positioning pins 6231 are inserted into the corresponding positioning grooves 661 to achieve precise feeding.

[0041] A power groove 662 is also formed on the auxiliary tooling 66. The power component can cooperate with the power hole and drive the auxiliary tooling 66 to move through the principle of gears.

[0042] It should be noted that through slots 414 are provided at both ends of the anode box 4 along the product conveying direction. The through slots 414 communicate with the working slot 413, and the bottom surface of the through slots 414 is lower than the top surface of the working slot 413, so that the product can enter the working slot 413. At the same time, due to the tension effect of the liquid medicine, the liquid medicine will not overflow from the through slots 414, thereby reducing the waste of the liquid medicine.

[0043] It should be noted that in this embodiment, the product to be electroplated is a terminal. The terminal includes a head 71, a main body 72 and a connecting part 73 connected in sequence. The head 71 needs to be electroplated. A plurality of clamping jaws are connected to the auxiliary tooling 66 and are suitable for clamping the connecting part 73 so that the head 71 faces the anode tank 41, which is convenient for electroplating. When electroplating other products, the corresponding auxiliary tooling 66 can be designed according to the specific products.

[0044] Working principle: During operation, the liquid medicine is stored in the anode tank 41. The liquid medicine enters from the storage tank 411 and overflows through the connection hole 412 into the working tank 413. Then, through the product conveying mechanism 6, the part of the product to be processed comes into contact with the liquid medicine in the working tank 413. At this time, both the anode part and the cathode part 65 are electrically connected to the product, facilitating electroplating of the part of the product to be processed. On the one hand, it can electroplate only the part of the product to be processed with high electroplating accuracy. On the other hand, only the part of the product to be processed comes into contact with the liquid medicine, resulting in less waste of the liquid medicine and significantly reducing costs.
