Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to a high-precision workpiece electroplating equipment. Background Technology

[0002] Electroplating is a process that uses electrolysis to deposit a thin layer of another metal or alloy onto the surface of certain metals. This technology uses electrolysis to coat the surface of metal or other material parts with a metallic film, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics. Electroplating technology is widely used in the electronics industry, communications, military industry, aerospace, and many other fields, and is an indispensable part of modern processing technology.

[0003] Despite the numerous advantages of electroplating technology, uneven plating remains a significant challenge in practical applications. Uneven plating not only affects the appearance and precision of the coating but can also reduce its performance, such as wear resistance and corrosion resistance. Particularly in fields with extremely high coating quality requirements, such as circuit board manufacturing in the electronics industry, uneven plating can lead to performance degradation and even malfunctions.

[0004] To address the problem of uneven electroplating, existing technologies have proposed several solutions, such as optimizing the composition of the electroplating solution, adjusting the current density, and improving fixture design. However, these solutions often have limitations, such as high cost, complex operation, and limited effectiveness. Utility Model Content

[0005] In view of the uneven electroplating problem and limitations of existing solutions, this invention aims to provide a new electroplating method or apparatus to effectively solve the problem of uneven electroplating. This invention uses a stirring clamping assembly to clamp a stirring cup in an inward circumferential direction, with the workpiece to be plated clamped at the bottom of the stirring cup. The stirring clamping assembly, stirring cup, and workpiece are then placed at an angle in the electroplating solution. Finally, during electroplating, the rotation of the stirring clamping assembly causes the workpiece to rotate in the electroplating solution, which helps ensure a uniform distribution of the plating layer on the surface of the workpiece, thereby effectively improving the quality and performance of the plating layer.

[0006] The present invention provides a high-precision workpiece electroplating equipment, comprising a motor, a stirring and clamping assembly, a stirring cup, a workpiece to be plated, an electroplating tank, an electroplating solution, and an electroplating plate.

[0007] The electroplating tank contains the electroplating solution, and the electroplating plate is placed in the electroplating solution. The stirring and clamping assembly clamps the stirring cup inward in a circumferential direction. The workpiece to be plated is clamped at the bottom of the stirring cup. The stirring and clamping assembly, the stirring cup, and the workpiece to be plated are all placed at an angle in the electroplating solution. The stirring and clamping assembly, the workpiece to be plated, and the electroplating plate are respectively connected to the motor through wires.

[0008] Furthermore, the workpiece to be plated is in the shape of a circular ring, and a filter screen is connected to the middle or bottom of the workpiece.

[0009] Furthermore, the stirring clamping assembly includes a vertically arranged first stirring rod, which is controlled by a motor to rotate. The bottom of the first stirring rod is forked and obliquely connected to two second stirring rods. The two second stirring rods are then connected to two vertically arranged third stirring rods. The bottom of the two third stirring rods is connected to a circular base, and a cross support rod is provided in the middle of the circular base. The stirring cup is placed on the circular base, and the third stirring component and the circular base together clamp the stirring cup.

[0010] Furthermore, the stirring clamping assembly is fixed to the stirring cup by a strap.

[0011] Furthermore, the electroplating plate is provided in two parts and is placed at both ends of the electroplating solution, and the stirring and clamping assembly is placed in the middle of the electroplating solution.

[0012] Furthermore, the stirring clamping assembly is provided with multiple components.

[0013] The beneficial effects of this utility model are:

[0014] This invention uses a stirring and clamping assembly to clamp a stirring cup inwards in a circumferential direction, with the workpiece to be plated positioned at the bottom of the stirring cup. The stirring and clamping assembly, the stirring cup, and the workpiece are then placed at an angle in the electroplating solution. During electroplating, the rotation of the stirring and clamping assembly causes the workpiece to rotate within the solution, ensuring a uniform distribution of the plating layer on the workpiece surface. This effectively enhances the electroplating effect, improves the quality and performance of the plating layer, and thus meets the requirements for electroplating workpieces with high precision. Furthermore, this invention has the advantages of simple structure, low cost, and easy operation. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 3 As shown, this utility model provides a high-precision workpiece electroplating equipment, which includes a motor 1, a stirring and clamping assembly 2, a stirring cup 3, a workpiece to be plated 4, an electroplating tank 5, an electroplating solution 6, and an electroplating plate.

[0023] The electroplating tank 5 contains an electroplating solution 6, and an electroplating plate (not shown) is provided in the electroplating solution 6. The stirring clamping assembly 2 clamps the stirring cup 3 inward in a circumferential direction. The bottom of the stirring cup 3 is clamped with the workpiece 4 to be plated. The stirring clamping assembly 2, the stirring cup 3, and the workpiece 4 to be plated are all placed at an angle in the electroplating solution 6. The stirring clamping assembly 2, the workpiece 4 to be plated, and the electroplating plate are respectively connected to the motor 1 through wires (not shown).

[0024] Specifically, the stirring clamping assembly 2 is connected to the output shaft of the motor 1. After the motor 1 is turned on, it drives the stirring clamping assembly 2 to rotate, thereby sequentially driving the stirring cup 3 and the workpiece to be plated 4 to tilt and rotate in the electroplating solution 6.

[0025] In this embodiment, when energized, the workpiece 4 to be plated serves as the cathode, and the plating metal on the electroplating plate serves as the anode. The cations of the plating metal are reduced on the surface of the workpiece 4 to form the plating layer. The plating metal can be zinc, chromium, nickel, etc., which have good corrosion resistance, protecting the base metal from corrosive media and extending the product's service life. Plating metals such as hard chromium and nickel have high hardness and wear resistance, improving the wear resistance of the product surface and reducing wear and scratches. Plating metals such as copper and silver have good electrical conductivity, suitable for electronics and electrical fields, improving the conductivity of the product. Plating metals such as gold, silver, and chromium have a bright and aesthetically pleasing appearance, enhancing the decorative effect of the product and satisfying people's pursuit of beauty.

[0026] Among them, such as Figure 1 As shown, crossbars 8 are fixedly installed on both sides of the electroplating tank 5, and several hooks 9 are connected to the crossbars 8. Figure 1 There are two hooks (9 in total), and the lower ends of the two hooks 9 together hold the electroplating plate, which is then completely immersed in the electroplating solution 6. The motor 1 is also equipped with a switch 11 and an adjustment knob 12, which are used to control the current switch and adjust the current, respectively.

[0027] In this embodiment, the stirring clamping assembly 2 clamps the stirring cup 3 inward in a circumferential direction, and the bottom of the stirring cup 3 is clamped with the workpiece 4 to be plated. Then, the stirring clamping assembly 2, the stirring cup 3, and the workpiece 4 to be plated are all placed at an angle in the electroplating solution 6. Finally, during electroplating, the rotation of the stirring clamping assembly 2 drives the workpiece 4 to rotate in the electroplating solution 6, which helps to make the contact between the electroplating solution 6 and the workpiece 4 to be plated uniform, thereby ensuring the uniform distribution of the coating on the surface of the workpiece 4 to be plated, and effectively enhancing the electroplating effect, improving the quality and performance of the coating, thus meeting the electroplating effect requirements of workpieces with high precision requirements.

[0028] In one alternative embodiment, the workpiece 4 to be plated is in the shape of a circular ring, and a filter screen 7 is connected to the middle or bottom of the workpiece 4.

[0029] Specifically, such as Figure 2As shown, the workpiece 4 to be plated is in the shape of a circular ring, and the filter screen 7 is circular and placed in the middle of the workpiece 4. The filter screen 7 can be fixedly connected to the workpiece 4 via straps. When the filter screen 7 is positioned below the workpiece 4, the workpiece 4 is secured in the stirring cup 3, and the filter screen 7 can be fixed by both the workpiece 4 and the stirring cup 3. The connection between the filter screen 7 and the workpiece 4 is detachable; if the filter screen 7 is damaged, it can be replaced by disassembly and reinstallation.

[0030] By setting a filter screen 7 in the middle or below the workpiece 4 to be plated, the electroplating solution 6 can pass through the filter screen 7 and enter the lower part of the workpiece 4 to be plated, which is beneficial for electroplating the lower surface of the workpiece 4 to be plated, and thus helps to further ensure uniform electroplating.

[0031] In one optional embodiment, the stirring clamping assembly 2 includes a vertically arranged first stirring rod 21, which is controlled by a motor 1 to rotate. The bottom of the first stirring rod 21 is forked and obliquely connected to two second stirring rods 22. The two second stirring rods 22 are then connected to two vertically arranged third stirring rods 23 respectively. The bottom of the two third stirring rods 23 is connected to a circular base 24. A cross support rod 241 is provided in the middle of the circular base 24. The stirring cup 3 is placed on the circular base 24, and the third stirring component and the circular base 24 together clamp the stirring cup 3.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, the output shaft of motor 1 is connected to the first stirring rod 21. After motor 1 starts, the output shaft rotates, driving the first stirring rod 21 to rotate. The first stirring rod 21 then drives the second stirring rod 22, the third stirring rod 23, the annular base 24, the stirring cup 3, and the workpiece 4 to be plated to rotate. The first stirring rod 21, the second stirring rod 22, the third stirring rod 23, the annular base 24, and the cross support rod 241 are integrally formed or fixed to each other by welding.

[0033] In one alternative embodiment, the stirring clamp assembly 2 is fixed to the stirring cup 3 by a strap.

[0034] Specifically, the mixing clamping component 2 and the mixing cup 3 are fixed together by straps, which helps to prevent the mixing cup 3 from being thrown away when it is tilted and rotated by the mixing clamping component 2, thus ensuring the normal operation of the electroplating work.

[0035] Furthermore, the specific method of setting the strap can be to make through holes on both sides of the upper end of the mixing cup 3, so that the strap passes through the through holes and is connected to the second stirring rod 22 to fix the upper part of the mixing cup 3; at the same time, the mixing cup 3 and the second stirring rod 22 can be fixed together inside the strap by a ring strap at the lower end of the mixing cup 3, thereby fixing the lower end of the mixing cup 3.

[0036] In some embodiments, the method of fixing the workpiece 4 to be plated and the stirring cup 3 can be to use a strap for fixing, or to fix the workpiece 4 to be plated by providing a snap-fit ​​groove at the lower end of the stirring cup 3.

[0037] In one alternative embodiment, two electroplating plates are provided and placed at both ends of the electroplating liquid 6, and the stirring clamping assembly 2 is placed in the middle of the electroplating liquid 6.

[0038] Specifically, by setting up two electroplating plates and placing them at both ends of the electroplating solution 6, and placing the stirring and clamping assembly 2 in the middle of the electroplating solution 6, that is, placing the workpiece 4 to be plated in the middle of the electroplating solution 6, it is beneficial to make the workpiece 4 to be plated contact the plating metal ions generated by the electroplating plates during electrolysis as much as possible, thereby improving the electroplating efficiency.

[0039] In one alternative embodiment, the stirring clamping assembly 2 is provided with multiple components.

[0040] Specifically, by setting up multiple stirring clamping components 2 to simultaneously clamp multiple workpieces 4 to be plated, it is beneficial to perform electroplating work on multiple workpieces 4 at the same time, thereby improving the overall electroplating efficiency.

[0041] The working process of this utility model:

[0042] Before electroplating, the workpiece 4 to be plated, the filter screen 7, and the stirring cup 3 are fixed together by means of strapping, snap-fit, etc. Then, the stirring clamping assembly 2 is taken out, and the stirring cup 3 is fixedly installed in the stirring clamping assembly 2 by means of strapping, snap-fit, etc. Then, the stirring clamping assembly 2 is inserted into the motor 1, so that the stirring clamping assembly 2 is connected to the output shaft of the motor 1.

[0043] Then, the electroplating plate is first fixed in the electroplating tank 5 by the crossbar 8 and hook 9, and then the workpiece 4 to be plated and the electroplating plate are connected to the motor 1 by wires. After that, the electroplating solution 6 (whose main components are conductive salts such as sodium sulfate and magnesium sulfate, as well as activators, buffers, additives, etc.) is introduced into the electroplating tank 5, and the workpiece 4 to be plated and the electroplating plate are completely immersed in the electroplating solution 6.

[0044] Finally, the motor 1 is started, causing the stirring and clamping assembly 2 to drive the workpiece 4 to be plated to tilt and rotate in the electroplating solution 6. At the same time, the motor 1 energizes the workpiece 4 to be plated and the plating metal on the electroplating plate, with the workpiece 4 acting as the cathode and the plating metal on the electroplating plate acting as the anode, thus starting the electroplating process, so that the cations of the plating metal are reduced on the surface of the workpiece 4 to form a plating layer.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
