Technical Field
[0001] This utility model belongs to the field of workpiece electroplating technology, and in particular relates to a device for partial silver plating of irregularly shaped electrical workpieces. Background Technology
[0002] Electroplating silver is a process that uses the principle of electrolysis to plate a thin layer of metallic silver onto the surface of certain metals. It is a process that uses electrolysis to attach a layer of metallic silver to the surface of metal or other material parts, thereby preventing metal oxidation, improving conductivity, and enhancing aesthetics.
[0003] In the electroplating process for irregularly shaped electrical workpieces, the area to increase conductivity is very small, resulting in high overall electroplating costs and uneconomical practices. Localized electroplating makes it difficult to protect the non-plated surfaces of irregularly shaped workpieces, leading to unreliable quality.
[0004] To address these issues, we provide a device for local silver plating of irregularly shaped electrical workpieces. Utility Model Content

[0008] The present invention is further configured such that the top of the contour base is slotted according to the lower part of the irregular workpiece, and the bottom of the contour cover is slotted according to the upper part of the irregular workpiece. The top of the contour base is slotted according to the lower part of the irregular workpiece, and the bottom of the contour cover is slotted according to the upper part of the irregular workpiece.

[0010] The present invention is further configured such that the inner cavity of the fitting groove is provided with a first mounting groove and a second mounting groove for installing the insulating block and the conductive block. The first mounting groove and the second mounting groove provided in the inner cavity of the fitting groove provide installation space for the insulating block and the conductive block, ensuring the stability and safety of the conductive rod installation and making the current conduction more reliable.
[0011] The present invention is further configured such that the conductive rod and the conductive block are made of copper alloy, and the side of the conductive block away from the conductive rod contacts the irregularly shaped workpiece.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1
[0026] Please see Figure 1-5This utility model is a device for partial silver plating of irregularly shaped electrical workpieces, including a contour base 1. Screws 2 are fixedly connected to the front and rear ends of one side of the top of the contour base 1 and the other side of the top. A contour cover plate 3 is sleeved on the top of the screws 2. An irregularly shaped nut 4 is threadedly connected to the top of the screws 2. A fitting groove 5 is opened on one side of the contour base 1 and the contour cover plate 3 facing each other. A conductive rod 6 is engaged in the inner cavity of the fitting groove 5. An insulating block 7 is fixedly connected to the straight end surface of the conductive rod 6. A conductive block 8 is fixedly connected to the surface of the conductive rod 6 and to one side of the insulating block 7.
[0027] Specifically: The contour base 1 serves as the foundation of the entire device. Screws 2 are vertically fixed to the front and rear ends of one side of its top and to the other side. These screws 2 provide support and positioning for the subsequent installation of the contour cover plate 3. The contour cover plate 3 is fitted onto the top of the screws 2. By rotating the irregular nut 4 at the top of the screws 2, the contour cover plate 3 can be tightly fixed to the contour base 1, thereby achieving clamping and positioning of the irregular workpiece. A fitting groove 5 is opened on one side of the contour base 1 and the contour cover plate 3 opposite to each other, used to engage the conductive rod 6. An insulating block 7 is fixed to the straight end surface of the conductive rod 6, serving to isolate current and prevent leakage. The conductive block 8, fixed to the surface of the conductive rod 6 and located on one side of the insulating block 7, is a key component for current conduction. It can transfer current to the irregular workpiece, providing the necessary conditions for the silver plating process.
[0028] Example 2
[0029] Please see Figure 1-5 Based on Embodiment 1, the top of the contour base 1 is slotted according to the lower part of the irregular workpiece, and the bottom of the contour cover plate 3 is slotted according to the upper part of the irregular workpiece. The contour cover plate 3 and the contour base 1 are hollowed out according to the electroplating position of the irregular workpiece. The inner cavity of the fitting groove 5 is provided with mounting groove 1 9 and mounting groove 2 10 for mounting insulating block 7 and conductive block 8. The conductive rod 6 and the conductive block 8 are made of copper alloy. The side of the conductive block 8 away from the conductive rod 6 contacts the irregular workpiece. The contour base 1, screw 2, contour cover plate 3, irregular nut 4 and insulating block 7 are all made of insulating engineering plastic. The top of the contour cover plate 3 is provided with mounting hole 11 for screw 2.
[0030] Specifically: the top of the contour base 1 is slotted according to the lower part of the irregular workpiece, and the bottom of the contour cover plate 3 is slotted according to the upper part of the irregular workpiece. This allows for precise fitting of the irregular workpiece's shape, ensuring the workpiece is firmly fixed in the device and improving the accuracy and consistency of silver plating. The contour cover plate 3 and contour base 1 are hollowed out according to the electroplating position of the irregular workpiece, clearly defining the area to be silvered and preventing the plating solution from contacting the non-plated surface, thus achieving the function of local silver plating while protecting the quality of the non-plated surface. The mounting slots 9 and 10 inside the fitting groove 5 provide installation space for the insulating block 7 and the conductive block 8, ensuring the stability and safety of the conductive rod 6 installation and making current conduction more reliable. 6 and conductive block 8 are made of copper alloy, which has good conductivity and can efficiently transfer current to irregularly shaped workpieces. The side of conductive block 8 away from conductive rod 6 contacts the irregularly shaped workpiece, ensuring the continuity of current conduction and improving the silver plating effect. The contour base 1, screw 2, contour cover plate 3, irregularly shaped nut 4 and insulating block 7 are all made of insulating engineering plastic, which has the characteristics of insulation and corrosion resistance, avoiding conductivity and corrosion during the silver plating process, extending the service life of the device, and ensuring the stability of the silver plating process. The mounting hole 11 on the top of the contour cover plate 3 through the screw 2 facilitates the installation and removal of the contour cover plate 3, making the operation of the device more convenient and improving work efficiency.
[0031] The working principle of this utility model is as follows: The irregularly shaped workpiece is placed on the contour base 1, matching the slot on the top of the contour base 1. Then, the conductive rod 6 is snapped into the inner cavity of the fitting groove 5, allowing the conductive block 8 to contact the irregularly shaped workpiece. Next, the contour cover plate 3 is fitted onto the screw 2 through the mounting hole 11 on the top, and the irregularly shaped nut 4 is rotated to tightly fit the contour cover plate 3 against the contour base 1, thereby clamping and fixing the irregularly shaped workpiece and the conductive rod 6. During the silver plating process, current is transmitted to the irregularly shaped workpiece through the conductive rod 6 and the conductive block 8. Because the contour cover plate 3 and the contour base 1 are hollowed out according to the electroplating position, the plating solution only contacts the area to be silvered, thus achieving localized silver plating of the irregularly shaped workpiece. Simultaneously, the insulating block 7 and components made of insulating engineering plastic ensure the safety and stability of the device, preventing leakage and corrosion.
[0032] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
