Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to a cathode conductive base and an electroplating device. Background Technique

[0002] Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain metals by using the electrolysis principle. It is a process of using electrolysis to attach a metal film to the surface of metal or other material parts, so as to prevent metal oxidation such as rust, and improve wear resistance, electrical conductivity, reflectivity, corrosion resistance and enhance beauty. The outer layer of many coins is also electroplated.

[0003] In practical applications, electroplating usually requires loading the workpiece to be plated through a tooling fixture, making the tooling fixture conduct the cathode through parts such as a conductive base, and matching with the anode in the electroplating tank. After the workpiece to be plated contacts the electroplating solution in the electroplating tank, it can be plated with metal. The existing conductive bases usually require additional structures for fastening to facilitate conduction, specifically referring to utility models such as CN207904395U and CN219059187U. This type of conductive base has a simple structure and is convenient for processing. However, after long-term use, the cathode and the conductive base are prone to detachment and poor contact, further resulting in power-on failure, and finally the plating of the workpiece to be plated fails.

[0004] Therefore, in order to solve the problem of poor contact between the electrode and the conductive base during conduction, a cathode conductive base and an electroplating device are designed. Content of the Utility Model

[0005] The utility model aims to overcome the above-mentioned defects in the prior art and provides a cathode conductive base, which solves the problem of poor contact between the electrode and the conductive base during conduction, thereby facilitating the plating of the workpiece to be plated.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a cathode conductive base, including a conductive base, a conductive block, an adjusting member and a conductive member. The conductive block is clamped into the interior of the conductive base. The bottom of the conductive base is connected to the conductive member through the adjusting member, and the adjusting member makes the conductive base and the conductive block always abut against each other.

[0007] As a preferred scheme of the utility model, a V-shaped notch is formed inside the conductive base, and the conductive block includes a V-shaped block adapted to the V-shaped notch.

[0008] As a preferred scheme of the utility model, the adjusting member includes a bolt and a spring. The top of the spring abuts against the bottom of the conductive base, and the bottom of the spring abuts against the top of the conductive member.

[0009] As a preferred scheme of the utility model, through holes are formed at both ends of the bottom of the conductive base, and the bolt passes through the through holes and the spring and is fixed on the conductive member.

[0010] As a preferred embodiment of the present utility model, the spring can be replaced with a spring plate.

[0011] An electroplating device includes a cathode conductive base, a tank body, and a tooling fixture. The conductive member is fixedly connected to the tank body. The tank body includes a support member. The side of the conductive block away from the conductive base is connected to the tooling fixture, and the tooling fixture is supported by the support member.

[0012] As a preferred embodiment of the present utility model, the conductive block includes a connecting seat, a threaded hole is formed on the connecting seat, and a long hole adapted to the threaded hole is formed on the tooling fixture.

[0013] As a preferred embodiment of the present utility model, the tank body includes an electroplating tank, and the electroplating tank contains electroplating solution.

[0014] As a preferred embodiment of the present utility model, the conductive member is connected to the negative electrode of the power supply, an anode plate is arranged in the electroplating tank, and the anode plate is connected to the positive electrode of the power supply.

[0015] As a preferred embodiment of the present utility model, the material of the conductive member is copper.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. An adjusting member with a spring is arranged between the conductive base and the conductive member of the present utility model, so that the conductive base can be adjusted up and down to adapt to the change in the height of the conductive block, ensuring that the conductive base and the conductive block are always in contact, thereby reducing the processing precision of the conductive base and the conductive block, enabling good contact and power conduction between the conductive base and the conductive block, and being beneficial to the stable progress of the electroplating process.

[0018] 2. Both the V-shaped block and the V-shaped notch of the present utility model are V-shaped, so that the outer side surface of the V-shaped block must be in contact with the inner side surface of the V-shaped notch, thereby not only ensuring that the conductive base stably supports the conductive block, but also ensuring stable power conduction between the conductive base and the conductive block.

Detailed implementation manners

[0023] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0024] In the following description, terms such as "inner", "outer", "upper", "lower", "left", "right", etc. indicating orientations or positional relationships are only for convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.

[0025] As Figure 1 shown, a cathode conductive base includes a conductive base 1, a conductive block 2, an adjusting member 3 and a conductive member 4. The conductive block 2 is snapped into the interior of the conductive base 1. The bottom of the conductive base 1 is connected to the conductive member 4 through the adjusting member 3. The adjusting member 3 enables the conductive base 1 and the conductive block 2 to be in contact at all times, reducing the machining accuracy requirements for the conductive base 1 and the conductive block 2 and ensuring stable power conduction between the conductive base 1 and the conductive block 2. A V-shaped notch 11 is formed inside the conductive base 1. The conductive block 2 includes a V-shaped block 21 adapted to the V-shaped notch 11.

[0026] Among them, the adjusting member 3 is a conductive adjusting member.

[0027] Specifically, the conductive member 4 is connected to the conductive base 1 through the adjusting member 3. After the conductive member 4 is energized, the conductive base 1 is also energized, and thus the conductive block 2 snapped into the interior of the conductive base 1 can also be energized. Since both the V-shaped block 21 and the V-shaped notch 11 are V-shaped, when the V-shaped block 21 is snapped into the V-shaped notch 11, the outer side surface of the V-shaped block 21 must be in contact with the inner side surface of the V-shaped notch 11, thereby not only ensuring that the conductive base 1 stably supports the conductive block 2, but also ensuring stable power conduction between the conductive base 1 and the conductive block 2.

[0028] In the present invention, both the V-shaped block 21 and the V-shaped notch 11 are V-shaped, so that the outer side surface of the V-shaped block 21 must be in contact with the inner side surface of the V-shaped notch 11, thereby not only ensuring that the conductive base 1 stably supports the conductive block 2, but also ensuring stable power conduction between the conductive base 1 and the conductive block 2.

[0029] The adjusting member 3 includes a bolt 31 and a spring 32. The top of the spring 32 abuts against the bottom of the conductive base 1, and the bottom of the spring 32 abuts against the top of the conductive member 4.

[0030] Through holes 12 are formed at both ends of the bottom of the conductive base 1, and the bolt 31 passes through the through holes 12 and the spring 32 and is fixed on the conductive member 4.

[0031] Specifically, the bolt 31 located between the conductive base 1 and the conductive member 4 functions to position the conductive base 1 on the conductive member 4. When the spring 32 located between the conductive base 1 and the conductive member 4 is subjected to the acting forces of the conductive base 1, the conductive block 2 and other parts, it generates a reaction force, enabling the conductive base 1 to be adjusted up and down to adapt to the change in the height of the conductive block 2, thereby ensuring good contact and power conduction between the conductive base 1 and the conductive block 2.

[0032] By the same token, in order to provide a reaction force to ensure good contact and power conduction between the conductive base 1 and the conductive block 2, the spring 32 is replaced with a spring piece, which can pass through the bolt 31 and is clamped between the conductive base 1 and the conductive member 4.

[0033] In this embodiment, there are 2 bolts 31 and 2 springs 32, which are symmetrically located on both sides of the conductive base 1 and can support the conductive base 1 more stably.

[0034] In the present utility model, an adjusting member 3 with a spring 32 is provided between the conductive base 1 and the conductive member 4, enabling the conductive base 1 to be adjusted up and down to adapt to the change in the height of the conductive block 2, so as to ensure that the conductive base 1 and the conductive block 2 are always in abutment, thereby reducing the processing precision requirements for the conductive base 1 and the conductive block 2, ensuring good contact and power conduction between the conductive base 1 and the conductive block 2, and facilitating the stable progress of the electroplating process.

[0035] As Figures 2 - 3 shown, an electroplating device includes the cathode conductive seat, a tank body 5 and a tooling fixture 6. The conductive member 4 is fixedly connected to the tank body 5. The tank body 5 includes a support member 52. One side of the conductive block 2 away from the conductive base 1 is connected to the tooling fixture 6. The tooling fixture 6 is carried by the support member 52. The tooling fixture 6 is connected to the conductive block 2. When the conductive block 2 is powered on, the tooling fixture 6 is also powered on.

[0036] The conductive block 2 includes a connecting seat 22. A threaded hole 221 is formed on the connecting seat 22. A long hole 61 adapted to the threaded hole 221 is formed on the tooling fixture 6. A bolt passes through the long hole 61 and the threaded hole 221 to realize the connection between the tooling fixture 6 and the conductive block 2. The provision of the long hole 61 facilitates the connection between the tooling fixture 6 and the conductive block 2.

[0037] The tank body 5 includes an electroplating tank 51 which contains electroplating solution. The electroplating solution needs to submerge the workpiece to be electroplated so that the outer surface of the workpiece to be electroplated can be electroplated completely.

[0038] The conductive part 4 is connected to the negative electrode of the power supply. The electroplating tank 51 is provided with an anode plate 7 which is connected to the positive electrode of the power supply.

[0039] The material of the conductive part 4 is preferably copper. The conductive part 4 can be a conductive copper bar. Of course, the material of the conductive part 4 can also be other conductive metals.

[0040] The working principle of the present utility model:

[0041] The workpiece to be electroplated is placed in the tooling fixture 6. The tooling fixture 6 is connected to the conductive block 2. The conductive block 2 is clamped into the conductive base 1. The conductive base 1 is connected to the conductive part 4 through the adjusting part 3. The anode plate 7 is located in the electroplating tank 51. The electroplating solution in the electroplating tank 51 submerges the workpiece to be electroplated and the anode plate 7. When the conductive part 4 is connected to the negative electrode of the power supply and the anode plate 7 is connected to the positive electrode of the power supply, a coating is formed on the surface of the workpiece to be electroplated.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
