Description

Technical Field

[0001] The embodiments of this utility model belong to the field of chain electroplating, and specifically relate to an anode structure, an anode electroplating component, and a chain electroplating device. Background Technology

[0002] Chains, as a commonly used power transmission component or a conventional connector, have been widely used in various fields. In some fields, in order to enhance the mechanical properties, wear resistance and / or rust prevention of chains, electroplating is required, such as chrome plating, nickel plating, copper plating, zinc plating and other treatments.

[0003] When electroplating chains, the chain needs to be immersed in an electroplating tank containing electroplating solution, with the portion of the chain to be electroplated connected to the cathode. Simultaneously, the electroplating material acts as the anode. During electroplating, the metal ions of the electroplating material are reduced to a metallic material through an electrode reaction under the influence of an external electric field, and then transferred to the portion of the chain to be electroplated, forming a metal deposition. However, the inventors discovered that since the chain is composed of multiple sequentially connected ring structures, ensuring the uniformity of electroplating on the inner surfaces of each ring structure requires not only that adjacent ring structures remain separated and do not contact each other during electroplating, but also that the metallic material formed by the reduction of the anode material through the electrode reaction be accurately transferred to the junction of the two ring structures. Therefore, this places high demands on the structure of the anode material and the positional relationship between the anode material and the chain. Utility Model Content

[0004] The purpose of this invention is to design an anode structure, an anode electroplating assembly, and a chain electroplating device, so that during chain electroplating, the metal material formed by the reduction of the anode after the electrode reaction can be accurately distributed at the joint of two adjacent ring structure parts of the chain, thus ensuring the uniformity of electroplating on the inner surface of each ring structure part, thereby improving the yield rate of the chain during electroplating.

[0005] To achieve the above objectives, embodiments of this utility model provide an anode structure, which is used to transfer metal ions reduced by the electrode reaction to the inner surface of the annular structure of the chain. The anode structure includes:

[0006] At least one electrical connection portion; and each of the electrical connection portions extends partially outward toward the positioning fixture and is connected to an external power source; each of the electrical connection portions extends partially inward toward the positioning fixture.

[0007] At least one guide portion; the number of the guide portions is the same as the number of the electrical connection portions and corresponds uniquely, each guide portion is connected to the uniquely corresponding electrical connection portion and extends in the direction of the gap formed between two adjacent annular structural members of the chain, such that at least a portion of each guide portion enters the gap.

[0008] In addition, embodiments of this utility model also provide an anodic electroplating assembly, the anodic electroplating assembly comprising:

[0009] Several anode structures as described above are arranged sequentially along the length of the chain;

[0010] In each of the anode structures, at least a portion of the guide portion is inserted into the gap formed between each pair of adjacent annular structural members of the chain.

[0011] In addition, embodiments of this utility model also provide a chain electroplating device, the chain electroplating device comprising:

[0012] Positioning fixtures are used to clamp and fix the various ring-shaped structural components of the chain along a preset straight line direction;

[0013] A plurality of cathodes; the number of cathodes is the same as the number of annular structural members of the chain, and they are uniquely and correspondingly arranged, with each cathode abutting against the uniquely corresponding annular structural member;

[0014] The anodic electroplating assembly as described above.

[0015] Compared to the prior art, the embodiments of this utility model have the following advantages: the anode structure includes at least one electrical connection portion and at least one guiding portion. Each electrical connection portion extends partially outward from the positioning fixture and is connected to an external power source. Simultaneously, each electrical connection portion also extends partially inward from the positioning fixture. Furthermore, each guiding portion is connected to a unique corresponding electrical connection portion and extends towards the gap formed between two adjacent annular structural members of the chain. Therefore, during application, the electrical connection portion can guide the current from outside the fixture to inside, ultimately guiding it to the guiding portion. This allows the metal material formed by the reduction reaction in the guiding portion to be accurately transferred to the joint of the two adjacent annular structural members, ensuring the uniformity of electroplating on the inner surfaces of each annular structural member and improving the yield rate of the chain during electroplating.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0025] Example 1

[0026] The first embodiment of this utility model relates to an anode structure, such as Figure 1 and Figure 2 As shown, the anode structure 1 is used to transfer metal ions formed by reduction through the electrode reaction to the inner surface of the annular structure 101 of the chain 10. Furthermore, as... Figure 1 , Figure 4 and Figure 6 As shown, the anode structure 1 includes at least one electrical connection portion 11 and at least one guide portion 12. Each electrical connection portion 11 extends partially outward toward the positioning fixture and is connected to an external power source. At the same time, each electrical connection portion 11 also extends partially inward toward the positioning fixture.

[0027] Additionally, in some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, the number of guide portions 12 is the same as the number of electrical connection portions 11, and they correspond uniquely. Furthermore, in combination... Figure 2 and Figure 3 As shown, each guide portion 12 is connected to a unique corresponding electrical connection portion 11 and extends toward the gap formed between two adjacent annular structural members 101 of the chain 10, so that each guide portion 12 partially enters the gap.

[0028] As can be seen from the above, since the anode structure 1 includes at least one electrical connection portion 11 and at least one guide portion 12, and each electrical connection portion 11 extends partially outward from the positioning fixture and is connected to an external power source, while each electrical connection portion 11 also extends partially inward from the positioning fixture. Furthermore, since each guide portion 12 is connected to a unique corresponding electrical connection portion, and each guide portion 12 extends towards the gap formed between two adjacent annular structural members 101 of the chain 10, in application, the electrical connection portion 11 can guide the current from outside the fixture to inside the fixture, and finally to the guide portion 12. This allows the metal material formed by the reduction of the electrode reaction in the guide portion 12 to be accurately transferred to the joint of the two adjacent annular structural members, ensuring the uniformity of electroplating on the inner surface of each annular structural member 101, thereby improving the yield rate of the chain during electroplating.

[0029] Specifically, in some embodiments, such as Figure 1 and Figure 4 As shown, each electrical connection portion 11 includes an electrical connection section 111 and a support section 112. The electrical connection section 111 extends outward from the positioning fixture and is also connected to an external power source. Secondly, as... Figure 1 and Figure 4 As shown, the support section 112 is connected to the electrical connection section 111, and the support section 112 extends into the interior of the positioning fixture, so that the support section 112 can point to the gap formed between two adjacent annular structural members 101. The guide section 12 is also connected to the end of the support section 112 away from the electrical connection section 111, so that the guide section 12 can enter the gap formed between any two adjacent annular structural members 101 of the chain 10.

[0030] Additionally, in some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the guide section 12 includes: at least one first guide segment 121 and at least one second guide segment 122. Wherein, combined with Figure 2 and Figure 3 As shown, each first guide segment 121 extends into the gap from one end of the support segment 112 away from the electrical connection segment 111, while each second guide segment 122 extends from any part of the first guide segment 121 in a direction intersecting the first guide segment 121. For example, when one second guide segment 122 is provided, such as... Figure 1 and Figure 2 As shown, the guide portion 12 at this time has an overall X-shaped or cross-shaped structure, so that the areas where the first guide segment 121 and the second guide segment 122 intersect can cover the joint area of ​​the inner side of the two adjacent annular structural members 101, thereby ensuring the uniformity of electroplating at the joint area of ​​the inner side of the two adjacent annular structural members 101. When multiple second guide segments 122 are provided, each second guide segment 122 is equidistantly arranged around any part of the first guide segment 121 as the axis, so that the guide part 12 is approximately in the shape of a cross. It is easy to see that by combining one or more second guide segments 122 with the first guide segment 121 respectively, the guide part 12 can cover the larger area of ​​the gap after being inserted into the gap between two adjacent annular structural members 101. This ensures that the metal material formed by the guide part 12 after reduction by the electrode reaction can be accurately transferred to the joint of the inner surface of the two adjacent annular structural members 101, ensuring the uniformity of the inner surface of each annular structural member 101 during electroplating, thereby improving the yield of the chain 10 during electroplating.

[0031] Furthermore, it should be noted that in some embodiments, the electrical connection segment 111 and the support segment 112 can be various structures, such as... Figure 1 The columnar structure shown can also be as follows: Figure 4 , Figure 5 and Figure 6 The bending structure shown allows the electrical connection part 11 to be electrically connected to an external power source, while also allowing the guide part 12 to enter the gap between two adjacent annular structural members.

[0032] Furthermore, as a preferred embodiment, in other embodiments, such as Figure 1 and Figure 2 As shown, the cross-sectional diameters of the first guide segment 121 and the second guide segment 122 are smaller than the cross-sectional diameter of the support segment 112, thus making the cross-sectional diameters of the first guide segment 121 and the second guide segment 122 thinner. This ensures that the guide part 12 can easily enter the gap formed between two adjacent annular structural members 101. The cross-sectional diameter of the support segment 112 is thicker, thus enabling the support segment 112 to provide stable support for the guide part 12. This ensures the uniformity of electroplating on the inner surface of each annular structural member 101.

[0033] Additionally, as a preferred embodiment, in other embodiments, such as Figure 7 As shown, multiple electrical connection portions 11 and guide portions 12 are provided, and each electrical connection portion 11 is equidistantly arranged around the center of the gap. Each electrical connection portion 11 includes an electrical connection section 113 and a support section 114. Among them, combined with... Figure 7 As shown, the electrical connection section 113 extends outward from the positioning fixture and is connected to an external power supply. Secondly, as... Figure 7 As shown, the support section 114 is connected to the electrical connection section 113, and the support section 114 extends into the positioning fixture, pointing towards the gap formed between two adjacent annular structural members 101. Additionally, as... Figure 7 As shown, the guide section 12 is also connected to the end of the uniquely corresponding support section 114 that is away from the electrical connection section 113.

[0034] Finally, in other embodiments, such as Figure 7 As shown, each guide portion 12 includes at least one guide segment 123, and each guide segment 123 extends into the gap from one end of the uniquely corresponding support segment 114 away from the electrical connection segment 113. For example, when there are four electrical connection portions 11 and four guide portions 12, and the four electrical connection portions 11 are equidistantly arranged around the center of the gap, the guide portions 12 formed by each guide segment 123 can have an X-shaped structure. Thus, when each guide portion 12 is inserted into the gap formed by the two annular structural members 101, each guide portion 12 can cover a larger area of ​​the gap. This ensures that the metal material formed by each guide portion 12 after reduction by the electrode reaction can be accurately transferred to the joint of the two adjacent annular structural members 101, ensuring the uniformity of the inner surface of each annular structural member 101 during electroplating, thereby improving the yield of the chain 10 during electroplating.

[0035] Furthermore, it should be noted that, in order to meet different electroplating requirements, in some embodiments, each guide segment 123 of any guide portion 12 can be a straight segment or a curved segment. Of course, in other embodiments, each guide segment 123 of any guide portion 12 can also adopt other structures. However, in this embodiment, the structure of the guide segment 123 is not specifically limited.

[0036] Example 2

[0037] Embodiment 2 of this utility model relates to an anode electroplating assembly, such as... Figure 2 and Figure 8 As shown, the anodic electroplating assembly includes several anode structures 1 as described in Embodiment 1, and each anode structure 1 is arranged sequentially along the length direction of the chain 10.

[0038] In each anode structure 1, the guide portion 12 is at least partially inserted into the gap formed between each pair of adjacent annular structural members 101 of the chain 10.

[0039] As can be seen from the above, since the anode structure 1 includes at least one electrical connection portion 11 and at least one guide portion 12, and each electrical connection portion 11 extends partially outward from the positioning fixture and is connected to an external power source, while each electrical connection portion 11 also extends partially inward from the positioning fixture. Furthermore, since each guide portion 12 is connected to a unique corresponding electrical connection portion, and each guide portion 12 extends towards the gap formed between two adjacent annular structural members 101 of the chain 10, in application, the electrical connection portion 11 can guide the current from outside the fixture to inside the fixture, and finally to the guide portion 12. This allows the metal material formed by the reduction of the electrode reaction in the guide portion 12 to be accurately transferred to the joint of the two adjacent annular structural members, ensuring the uniformity of electroplating on the inner surface of each annular structural member, thereby improving the yield rate of the chain during electroplating.

[0040] Example 3

[0041] Embodiment three of this utility model relates to a chain electroplating device, such as... Figure 8 As shown, the chain electroplating device includes: positioning fixture 3, several cathodes 2, and an anode electroplating assembly as described in Example 2.

[0042] In some embodiments, such as Figure 8 As shown, the positioning fixture engages and fixes each of the annular structural members 101 of the chain 10 along a preset straight line. Furthermore, the number of cathodes 2 is the same as the number of annular structural members 101 of the chain 10, and they are uniquely matched. Simultaneously, each cathode 2 abuts against its uniquely corresponding annular structural member 101.

[0043] As can be seen from the above, since the anode structure 1 includes at least one electrical connection portion 11 and at least one guide portion 12, and each electrical connection portion 11 extends partially outward from the positioning fixture and is connected to an external power source, while each electrical connection portion 11 also extends partially inward from the positioning fixture. Furthermore, since each guide portion 12 is connected to a unique corresponding electrical connection portion, and each guide portion 12 extends towards the gap formed between two adjacent annular structural members 101 of the chain 10, in application, the electrical connection portion 11 can guide the current from outside the fixture to inside the fixture, and finally to the guide portion 12. This allows the metal material formed by the reduction of the electrode reaction in the guide portion 12 to be accurately transferred to the joint of the two adjacent annular structural members, ensuring the uniformity of electroplating on the inner surface of each annular structural member, thereby improving the yield rate of the chain during electroplating.

[0044] Specifically, in some embodiments, combined with Figure 6 and Figure 8As shown, the positioning fixture 3 includes several snap-fit ​​components 31, the number of which is the same as the number of annular structural members 101 of the chain 10, and they correspond uniquely. Each snap-fit ​​component 31 snaps into its unique corresponding annular structural member 10 along a preset straight line. Each pair of adjacent snap-fit ​​components 31 is arranged perpendicularly to each other. It is easy to see that because each pair of adjacent snap-fit ​​components 31 is arranged perpendicularly to each other, the annular structural members 101 snapped and fixed by each snap-fit ​​component 31 can be separated from each other along mutually perpendicular directions, preventing contact between adjacent pairs of annular structural members 101 of the chain 10. This ensures the uniformity of electroplating on the electroplated areas of each annular structural member 101 of the chain 10.

[0045] Furthermore, it is worth noting that in other embodiments, such as Figure 6 As shown, each snap-fit ​​assembly 31 includes a first snap-fit ​​member 311 and a second snap-fit ​​member 312, and the first snap-fit ​​member 311 and the second snap-fit ​​member 312 can respectively snap-fit ​​and fix the annular structure 101 along the length or width direction of the annular structure 101. For example, as Figure 6 As shown, the first snap-fit ​​member 311 and the second snap-fit ​​member 312 can be semi-enclosed cover structures, so that after the first snap-fit ​​member 311 and the second snap-fit ​​member 312 complete the snap-fit ​​of the annular structure member 101, the inner side of the annular structure member 101 can be exposed, while the outer surface of the annular structure member 101 can be directly covered by the first snap-fit ​​member 311 and the second snap-fit ​​member 312. This allows the anode material 2 to be reduced to a metal material through the electrode reaction, so that the metal material can only be transferred to the inner side of the annular structure member 101 and not to the outer surface of the annular structure member 101. Thus, electroplating can be achieved on the inner side of each annular structure member 101 of the chain 10.

[0046] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
