Description

Technical Field

[0001] The embodiments of the present invention belong to the field of chain electroplating, and in particular, relate to a chain electroplating method and device. Background Art

[0002] Chain, as a commonly used power transmission part or as a conventional connecting part, has been widely used in various fields. In some fields, in order to enhance the mechanical properties, wear resistance and / or rust resistance of the chain, the chain needs to be electroplated, such as chrome plating, nickel plating, copper plating, zinc plating, etc.

[0003] When electroplating a chain, the chain needs to be immersed in an electroplating tank containing an electroplating solution, and the part of the chain to be electroplated is connected to the cathode, and the electroplating material is used as the anode. During the electroplating process, the metal ions of the electroplating material are reduced to metal materials through electrode reactions under the action of an external electric field, and transferred to the part of the chain to be electroplated, so that a metal deposition process is formed at the part of the chain to be electroplated. However, the inventors have found that since the chain is composed of a plurality of annular structural parts connected in sequence, it is inevitable that two adjacent annular structural parts will come into contact during the electroplating process, resulting in the contact parts of the inner side surfaces of the annular structural parts of the chain being unable to be precipitated by the anode, which will cause uneven electroplating or electroplating failure on the inner side surfaces of the annular structural parts of the chain. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to design a chain electroplating method and device to ensure the uniformity of electroplating on the inner side surfaces of each annular structural member of the chain, thereby improving the yield rate of the chain during electroplating.

[0005] In order to achieve the above object, an embodiment of the present invention provides a chain electroplating method, which comprises the following steps:

[0006] Providing a positioning tool, and using the positioning tool to clamp and fix the annular structures of the chain along the length direction of the chain, so that the annular structures are separated from each other and do not contact each other; wherein, after the annular structures of the chain are fixed, they are respectively electrically connected to the cathode assembly arranged on the positioning tool;

[0007] The positioning device is placed in a tank containing an electrolyte solution so that the chain is completely immersed in the electrolyte solution;

[0008] Current is applied to the anode assembly disposed on the positioning fixture, so that the metal material formed by the reduction of the anode assembly through electrode reaction is continuously transferred to at least the inner side surface of each of the annular structural members.

[0009] In addition, an embodiment of the present invention further provides a chain electroplating device, wherein the chain positioning device comprises:

[0010] Positioning tooling; clamping and positioning the annular structural members of the chain along the length direction of the chain; the positioning tooling can be placed in a liquid tank containing an electrolyte solution so that the chain is completely immersed in the electrolyte solution of the liquid tank; wherein, after being clamped and positioned by the positioning tooling, the annular structural members are separated from each other and do not contact each other;

[0011] A cathode assembly, disposed on the positioning fixture and electrically connected to each of the annular structural members;

[0012] The anode assembly is arranged on the positioning fixture so that the metal material formed by reduction through electrode reaction is continuously transferred to at least the inner side surface of each of the annular structural members.

[0013] Compared with the prior art, in the embodiment of the present invention, during the electroplating process of the chain, the various annular structures of the chain can be clamped and fixed along the length direction of the chain by means of a positioning tool, so that the various annular structures are separated from each other and do not contact each other. Therefore, when current is applied to the anode assembly, the metal material formed by the reduction of the anode assembly through the electrode reaction can be continuously transferred to at least the inner side surface of each annular structure, thereby ensuring the uniformity of the electroplating on the inner side surface of each annular structure of the chain, thereby improving the yield rate of the chain during electroplating.

[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0039] Embodiment 1

[0040] Embodiment 1 of the present invention relates to a chain electroplating method, such as Figure 1 As shown, the chain electroplating method comprises the following steps:

[0041] Step 110, providing a positioning tool, and using the positioning tool to clamp and fix the annular structures 201 of the chain 20 along the length direction of the chain 20, so that the annular structures 201 are separated from each other and do not contact each other. Fig. 9 As shown, after being fixed, each annular structure 201 of the chain 20 is electrically connected to the cathode assembly 3 disposed on the positioning fixture.

[0042] Step 120 , placing the positioning device in a tank containing an electrolyte solution, so that the chain 20 is completely immersed in the electrolyte solution.

[0043] Step 130 , applying current to the anode assembly 2 disposed on the positioning fixture, so that the metal material formed by the electrode reaction reduction of the anode assembly 2 is continuously transferred to at least the inner side surface of each annular structure 201 .

[0044] It is not difficult to see from the above that during the electroplating process, the chain 20 can be fixed by the positioning tool along the length direction of the chain 20 to the annular structural members 201 of the chain 20, so that the annular structural members 201 are separated from each other and do not contact each other. Figure 4 and Figure 7 As shown, the metal material formed by the reduction of the anode assembly 2 by the electrode reaction can be continuously transferred to at least the inner side surface 2011 of each annular structure 201, thereby ensuring the uniformity of the electroplating of the inner side surface 2011 of each annular structure 201 of the chain 20, thereby improving the yield rate of the chain 20 during electroplating.

[0045] Specifically, in order to effectively clamp and fix the annular structures 201 of the chain 20 with the positioning tool, along the length direction of the chain 20, in some embodiments, the step of clamping and fixing the annular structures 201 of the chain 20 with the positioning tool, that is, step 110 specifically includes:

[0046] Each annular structure 201 is sequentially inserted into the positioning fixture along the length direction of the chain 20, from one end to the other end of the chain 20. Alternatively, in other embodiments, each annular structure 201 is sequentially inserted into the positioning fixture along the length direction of the chain 20, from both ends of the chain 20 toward each other.

[0047] In addition, it is worth mentioning that after the chain 20 is positioned by the positioning tool, each two adjacent annular structures 201 of the chain 20 along its length direction are vertically staggered. And, it is worth mentioning that in order to enable the positioning tool to realize the clamping positioning of each annular structure 201 of the chain 20. In some embodiments, Fig.10 As shown, the positioning tool includes: a plurality of positioning components 1. Among them, each positioning component 1 is sequentially arranged along the length direction of the chain 20, and the number of the positioning components 1 is the same as the number of the annular structural members 201 of the chain 20, and they are arranged uniquely, and each positioning component 1 is also clamped with the unique corresponding annular structural member 201. And, as Fig.10 and Fig.11 As shown, every two adjacent positioning components 1 are arranged crosswise and perpendicularly to each other, and every two adjacent annular structures 201 are clamped and fixed in directions perpendicular to each other, so that every two adjacent annular structures 201 are separated from each other.

[0048] Embodiment 2

[0049] A second embodiment of the present invention relates to a chain electroplating device, such as Figure 8 and Fig. 9 As shown, the chain positioning device includes: a positioning tool, a cathode assembly 3 and an anode assembly 2.

[0050] Among them, Figure 2 As shown, the positioning tool clamps each annular structure 201 of the positioning chain 20 along the length direction of the chain 20, so that each annular structure 201 can be separated from each other and not in contact with each other after being clamped and positioned by the positioning tool (not shown in the figure). In addition, the positioning tool can be placed in a liquid tank (not shown in the figure) containing an electrolyte solution, so that the chain 20 is completely immersed in the electrolyte solution in the liquid tank.

[0051] In addition, in some embodiments, Figure 8 and Fig. 9As shown, the cathode assembly 3 is arranged on the positioning fixture and is electrically connected to each annular structure 201. Figure 7 As shown, the anode assembly 2 is also arranged on the positioning fixture, so that the metal material formed by the reduction of the anode assembly 2 through the electrode reaction is continuously transferred to at least the inner side surface 2011 of each annular structure 201.

[0052] It is not difficult to see from the above content that during the electroplating process of the chain 20, the positioning tool can be used to clamp and fix the annular structures 201 of the chain 20 along the length direction of the chain 20, so that the annular structures 201 are separated from each other and do not contact each other. Secondly, since the cathode assembly 3 is also provided on the positioning tool, and the cathode assembly 3 is also electrically connected to the annular structures 201 of the chain 20, when current is applied to the anode assembly 2, the metal material formed by the reduction of the anode assembly 2 by the electrode reaction can be continuously transferred to at least the inner side surface 2011 of each annular structure 201, thereby ensuring the uniformity of the electroplating of the inner side surface 2011 of each annular structure 201 of the chain 20, thereby improving the yield rate of the chain 20 during electroplating.

[0053] Specifically, in some embodiments, Figure 8 and Fig. 9 As shown, the cathode assembly 3 includes a plurality of cathode components 31, and the number of cathode components 31 is the same as the number of the positioning assembly 1, and they are uniquely corresponding, and each cathode component 31 is partially inserted into the positioning fixture and abuts against the uniquely corresponding annular structure 201, so that each cathode component 31 can be electrically connected to the uniquely corresponding annular structure 201. At the same time, each cathode component 31 is also partially exposed outside the positioning fixture and is connected to an external power source.

[0054] In addition, combined Figures 10 to 13 As shown, the positioning tooling includes: a plurality of positioning components 1. The number of positioning components 1 is the same as the number of annular structures 201, and they are uniquely arranged. The positioning components 1 are sequentially connected along the length direction of the chain 20, and the number of positioning components 1 is the same as the number of annular structures 201 of the chain 20, and they are uniquely arranged. Each positioning component 1 is also clamped with the uniquely arranged annular structure 201.

[0055] Among them, Fig.10 and Fig.11 As shown, each two adjacent positioning components 1 are arranged crosswise and perpendicularly to each other, and each two adjacent annular structures 201 are clamped and fixed in directions perpendicular to each other, so that each two adjacent annular structures 201 are separated from each other and do not contact each other, and any positioning component 1 is used to be penetrated by the uniquely corresponding cathode component 31, so that the cathode component 31 is abutted against the uniquely corresponding annular structure 201.

[0056] Furthermore, in order to enable the positioning assembly 1 to clamp and fix the annular structure 201 , the positioning assembly 1 includes: a first clamping member 11 and a second clamping member 12 .

[0057] In some embodiments, in combination Figures 2 to 7 As shown, the first clamping member 11 and the second clamping member 12 are arranged opposite to each other, so that the annular structure 201 is clamped between the first clamping member 11 and the second clamping member 12, and at least the inner side surface 2011 of the annular structure 201 is exposed outside the first clamping member 11 and the second clamping member 12, for receiving the metal material formed by electrode reaction reduction from the anode member 21.

[0058] In addition, in some embodiments, the first clamping member 11 and the second clamping member 12 are both insulating components, and are combined with Figure 4 and Figure 7 As shown, the first clamping member 11 and / or the second clamping member 12 is also used to be penetrated by the cathode member 31 so that the cathode member 31 abuts against the annular structure member 201 .

[0059] It is not difficult to see that, since the positioning assembly 1 includes the first clamping member 11 and the second clamping member 12, and the first clamping member 11 and the second clamping member 12 are arranged opposite to each other, the annular structure 201 can be clamped between the first clamping member 11 and the second clamping member 12, so that when any annular structure 201 of the chain 20 is clamped and fixed by the first clamping member 11 and the second clamping member 12, the inner side 2011 of the annular structure 201 can be exposed outside the first clamping member 11 and the second clamping member 12, and because the first clamping member The first clamping component 11 and the second clamping component 12 are both insulating components, so that the metal material formed by the reduction of the anode component 21 through the electrode reaction can be isolated by the first clamping component 11 and the second clamping component 12, so that the metal material cannot be transferred to the part covered by the first clamping component 11 and the second clamping component 12, but can only be transferred to the inner side surface 2011 of the annular structure 201, thereby completing the electroplating of the inner side surface 2011 of the annular structure 201, and ensuring the uniformity of the electroplating of the inner side surface 2011 of each annular structure 201 of the chain 20.

[0060] Specifically, in some embodiments, Figure 2As shown, a first clamping groove 111 is provided on one side of the first clamping member 11 relative to the second clamping member 12, and a second clamping groove 121 is provided on one side of the second clamping member 12 relative to the first clamping member 11. Moreover, the groove wall of the first clamping groove 111 of the first clamping member 11 at least fits with the outer side of the annular structure 201, and the groove wall of the second clamping groove 121 of the second clamping member 12 at least fits with the outer side of the annular structure 201, so that an annular area 13 is formed between the first clamping member 11 and the second clamping member 12, which can be used for the metal material formed by the reduction of the anode member 21 through the electrode reaction to be transferred to the inner side surface 2011 of the annular structure 201.

[0061] In addition, it is worth mentioning that in some embodiments, Figure 2 and Figure 5 As shown, the first clamping member 11 and the second clamping member 12 clamp and position the annular structure 201 along the width direction of the annular structure 201. Fig.12 As shown, the first clamping member 11 and the second clamping member 12 can also clamp and position the annular structure 201 along the length direction of the annular structure 201. Figure 2 and Figure 5 As shown, the first clamping member 11 and the second clamping member 12 are also provided with a channel 14 connected to the annular area 13, through which the electrolyte solution in the liquid tank can enter the annular area 13, so that the metal material formed by each anode member 21 after reduction by electrode reaction can be dispersed in the electrolyte solution and enter the annular area 13 through the channel 14 of each first clamping member 11 and the second clamping member 12, so that the metal material dispersed in the electrolyte solution can be transferred to the inner side surface 2011 of the annular structure 201 to achieve electroplating of the inner side surface 2011 of the annular structure 201.

[0062] Furthermore, it should be noted that, in some embodiments, the channel 14 may be provided on the first clamping member 11 and the second clamping member 12, respectively, or in other embodiments, such as Figure 2 and Figure 5As shown, the channel 14 may also include: a first liquid tank 141 disposed on the first clamping member 11, and a second liquid tank 142 disposed on the second clamping member 12. Specifically, the first liquid tank 141 may be disposed on a side of the first clamping member 11 relative to the second clamping member 12, and the second liquid tank 142 may be disposed on a side of the second clamping member 12 relative to the first clamping member 11, so that when the first clamping member 11 and the second clamping member 12 complete the clamping of the annular structure 201, the first liquid tank 141 and the second liquid tank 142 may be opposite to each other and jointly enclose the channel 14, and the channel 14 may extend along the length direction of the chain 200, so that the channel 14 may introduce the electrolyte solution into the annular region 13, so that the metal material formed by each anode member 21 after reduction by electrode reaction may also enter the annular region 13 through the channel 14 under the fluidity of the electrolyte solution.

[0063] In addition, it is worth mentioning that in some other embodiments, such as Figure 5 and Figure 7 As shown, the first clamping member 11 and / or the second clamping member 12 can also be detachably provided with a locking member 15, and the locking member 15 is used to fix the anode member 21, so that a portion of the anode member 21 enters the annular area 13 surrounded by the first clamping member 11 and the second clamping member 12. For example, the locking member 15 can be a bolt, and is threadedly connected to the first clamping member 11 and / or the second clamping member 12, so that the locking member 15 can realize the locking and fixing of the anode member 21 on the first clamping member 11 and / or the second clamping member 12.

[0064] Furthermore, it should be noted that when the first clamping member 11 and the second clamping member 12 are clamped and positioned on the annular structure 10 along the width direction of the annular structure 201, in order to enable the first clamping member 11 to clamp and fix the annular structure 201 through the first clamping groove 111, in some embodiments, such as Figure 7 As shown, the first clamping member 11 includes: a first upper shielding cover 112 and a first lower shielding cover 113, and the first upper shielding cover 112 and the first lower shielding cover 113 can be arranged relative to each other along the thickness direction of the annular structure 201, so that a first clamping groove 111 can be formed between the first upper shielding cover 112 and the first lower shielding cover 113. Therefore, when the annular structure 201 is clamped and fixed, the annular structure 201 can be respectively embedded in the first upper shielding cover 112 and the first lower shielding cover 113, so that the first clamping member 11 can realize the clamping of the annular structure 201 through the first clamping groove 111.

[0065] Similarly, in order to enable the second clamping member 12 to clamp and fix the annular structure 201, in other embodiments, such as Figure 7As shown, the second clamping member 12 includes: a second upper shielding cover 122 and a second lower shielding cover 123, and the second upper shielding cover 122 and the second lower shielding cover 123 can be arranged relative to each other along the thickness direction of the annular structure 201, so that a second clamping groove 121 can be formed between the second upper shielding cover 122 and the second lower shielding cover 123. Therefore, when the annular structure 201 is clamped and fixed, the annular structure 201 can be embedded in the second upper shielding cover 122 and the second lower shielding cover 123 respectively, so that the second clamping member 12 can realize the clamping of the annular structure 201 through the second clamping groove 121.

[0066] In addition, in other embodiments, in order to enable the metal material formed by the anode assembly 2 after electrode reaction reduction to be directly transferred to the inner side surface 2011 of each annular structure 201. Fig.12 As shown, the anode assembly 2 includes: a plurality of anode pieces 21, and each anode piece 21 extends along the length direction of the chain 20, and at least one anode piece 21 passes through the intersection area of ​​each two adjacent positioning assemblies 1.

[0067] Furthermore, in order to realize the positioning of each anode member 21 on the positioning tool, in other embodiments, such as Fig.12 As shown, the chain electroplating device further includes: a hanging assembly 4, and the hanging assembly 4 includes: a hanging member 41 and at least one positioning member 42. Among them, the hanging member 41 is hung on the positioning tooling, and, as shown in Fig.13 As shown, the hanging member 41 has a front end 411 and a rear end 412 away from the front end 411. In addition, the hanging member 41 has at least one bending portion 413 from the front end 411 to the rear end 412, so that the front end 411 and the rear end 412 are opposite to each other.

[0068] In addition, in some other embodiments, Fig.12 and Fig.13 As shown, each positioning member 42 is arranged on the hanging member 41. Moreover, when there are multiple positioning members 42, each positioning member 42 is sequentially arranged from the front end 411 to the rear end 412, and each positioning member 42 is used to fix the anode member 21, so that the fixed anode member 21 is positioned in the intersection area of ​​each adjacent two positioning components 1 of the positioning tool.

[0069] Furthermore, it should be noted that in other embodiments, such as Fig.12 As shown, the bending portion 413 has several, for example, Fig.13 As shown, the bending portion 413 at least includes: a first side bending portion 413A, a second side bending portion 413B and a top bending portion 413C. Fig.12 and Fig.13As shown, the first side bending portion 413A includes: a plurality of first bending segments 413A1 formed by bending several times from the front end 411 toward the top direction of the positioning tooling. Secondly, the second side bending portion 413B includes: a plurality of second bending segments 413B1 formed by bending several times from the end 412 toward the top direction of the positioning tooling. Finally, the top bending portion 413C is respectively connected to an end of the first side bending portion 413A away from the front end 411 and an end of the second side bending portion 413B away from the end 412. Through the multiple first bending segments 413A1 of the first side bending portion 413A and the multiple second bending segments 413B1 of the second side bending portion 413B, the front end 411 and the end 412 of the hanger 41 can be opposite to each other, and in other embodiments, combined with Fig.12 and Fig.13 As shown, the first side bending portion 413A, the second side bending portion 413B and the top bending portion 413C are also respectively provided with at least one positioning member 42, so that the hanging assembly 4 can respectively realize the positioning of multiple anode components 21 around the circumference of the positioning tooling, thereby further ensuring the uniformity of the electroplating of the inner side surface 2011 of each annular structural component 201 of the chain 20.

[0070] Of course, as an alternative, in other embodiments, such as Figure 5 As shown, each anode component 21 of the anode assembly 2 is partially guided into the gap formed between any two adjacent annular structural components 201, so that the metal material formed by the electrode reaction of each anode component 21 can be transferred to the joint of the inner side surfaces 2011 of the two adjacent annular structural components 201.

[0071] Furthermore, it should be noted that this embodiment is an embodiment of the chain positioning device corresponding to the first embodiment, and this embodiment can be implemented in conjunction with the first embodiment. In addition, the relevant technical details mentioned in the first embodiment are still valid in this embodiment, and in order to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied in the second embodiment.

[0072] Embodiment 3

[0073] The third embodiment of the present invention relates to a chain electroplating device. The third embodiment is substantially the same as the second embodiment, and the main difference is that the structure of the positioning component 1 is different from that of the positioning component 1 in the second embodiment. In this embodiment, Fig.14 , 17 and Fig.19 As shown, the positioning assembly 1 includes: a connecting portion 16 , a first supporting portion 17 , a second supporting portion 18 , a first clamping portion 19 and a second clamping portion 10 .

[0074] Wherein, in some embodiments, Fig.17 and Fig.24As shown, the connection part 16 includes: a head end 161 and a tail end 162 away from the head end 161, and the connection part 16 is bent and extended from the head end 161 to the tail end 162, so that the connection part 16 is clamped and positioned on the crossbeam 5 of the positioning tool.

[0075] Secondly, if Fig.16 and 17 As shown, the first support portion 17 is connected to the head end 161 of the connecting portion 16, and the first support portion 17 also extends in a direction away from the head end 161. The second support portion 18 is also connected to the tail end 162 of the connecting portion 16, and the second support portion 18 also extends in a direction away from the tail end 162.

[0076] Finally, if Fig.17 and Fig.23 As shown, the first clamping portion 19 is connected to the end of the first support portion 17 away from the head end 161, and the second clamping portion 10 is connected to the end of the second support portion 18 away from the tail end 162. The first clamping portion 19 and the second clamping portion 10 are arranged opposite to each other and clamp the annular structure 201.

[0077] It is not difficult to see from the above content that since each positioning component 1 can be positioned on the beam 5 of the positioning tooling through the connecting part 16, multiple positioning components 1 can be arranged in sequence along the length direction of the beam 5, and the first clamping part 19 and the second clamping part 10 of each positioning component 1 can be arranged relative to each other through the first supporting part 17 and the second supporting part 18, so that the first clamping part 19 and the second clamping part 10 can realize clamping and fixing of each annular structure 201 of the chain 20, ensuring that each annular structure 1 of the chain 20 is fixed during electroplating. Therefore, by clamping and fixing each annular structure 201, each annular structure 201 of the chain 20 can be separated from each other to avoid direct contact between two adjacent annular structures 201, thereby ensuring the uniformity of electroplating of the inner side surface 2011 of each annular structure 201 of the chain 20 and improving the yield rate of the chain 20 during electroplating.

[0078] Specifically, the positioning component 1 can have a variety of structures. For example, in some embodiments, Fig.17 , Fig.19 and Fig.21 As shown, the first support portion 17 of the positioning assembly 1 can be parallel to the second support portion 18, so that the first clamping portion 19 and the second clamping portion 10 are arranged opposite to each other along the length direction of the first support portion 17 or the second support portion 18. Alternatively, in other embodiments, such as Fig.23 and Fig.24As shown, the first supporting portion 17 and the second supporting portion 18 of the positioning assembly 1 extend from one end connected to the connecting portion 16 to the other end, gradually tilting away from each other, so that the first clamping portion 19 and the second clamping portion 10 are arranged opposite to each other along the relative direction of the first supporting portion 17 and the second supporting portion 18.

[0079] Furthermore, in order to enable the first clamping portion 19 and the second clamping portion 10 to have a greater clamping force on the annular structure 1, in some embodiments, such as Fig.14 and Fig. 22 As shown, the first support portion 17 and the second support portion 18 can be elastically deformed in directions relative to each other, so that the first clamping portion 19 and the second clamping portion 10 can have a stronger clamping force on the annular structure 201 with the help of the first support portion 17 and the second support portion 18, thereby better clamping and positioning the annular structure 201 of the chain.

[0080] It is worth mentioning that Fig.18 , Fig.19 , Fig. 20 and Fig.21 As shown, when the first support portion 17 is parallel to the second support portion 18, the length of the first support portion 17 is greater than the length of the second support portion 18, so that the first clamping portion 19 and the second clamping portion 10 can be arranged relative to each other along the length direction of the first support portion 17 or the second support portion 18, so that the first clamping portion 19 and the second clamping portion 10 can clamp the annular structure 201 of the chain 20 along the length direction of the first support portion 17 or the second support portion 18, as shown in FIG. Fig.14 When the first support portion 17 and the second support portion 18 extend from one end connected to the connecting portion 16 to the other end, gradually extending away from each other, as shown in FIG. Fig.24 As shown, the first clamping portion 19 and the second clamping portion 10 are arranged relative to each other along the relative direction of the first supporting portion 17 and the second supporting portion 18, and the first clamping portion 19 and the second clamping portion 10 can be clamped to the annular structure 201 of the chain 20 along the length direction of the first supporting portion 17 or the second supporting portion 18, as shown in FIG. Fig. 22 and Fig.23 Status shown.

[0081] Also, it is worth noting that in some embodiments, such as Fig.19As shown, the first clamping portion 19 at least includes: a first bending section 191, which is connected to one end of the first support portion 17 away from the connecting portion 16. At the same time, the second clamping portion 10 at least includes: a second bending section 101, which is connected to one end of the second support portion 18 away from the connecting portion 16. The first bending section 191 and the second bending section 101 are opposite to each other, and a clamping area is formed between the first bending section 191 and the second bending section 101, and the clamping area is used to clamp and fix the annular structure 201.

[0082] However, as a preferred solution, in some embodiments, such as Fig.18 , Fig.19 and Fig.24 As shown, there are two first bending sections 191, and the two first bending sections 191 are arranged parallel to each other, and one of the first bending sections 191 is connected to the first supporting portion 17. Fig.18 and Fig.19 As shown, the positioning assembly 1 further includes a reinforcing portion 100 , and the reinforcing portion 100 is disposed between the two first bending sections 191 and is respectively connected to the two first bending sections 191 .

[0083] Specifically, in some embodiments, Fig.15 , Fig.19 and Fig. 20 As shown, the reinforcing portion 100 includes: two first extension segments 1001 and a connecting segment 1002. Any one of the first extension segments 1001 is bent and extended from one end connected to one of the first bending segments 191 in a direction away from the first supporting portion 17. The other first extension segment 1001 is bent and extended from one end connected to the other first bending segment 191 in a direction away from the first supporting portion 17. Fig.19 and Fig. 20 As shown, the connecting section 1002 is disposed between the two first extension sections 1001 and is respectively connected to one end of the two first extension sections 1001 away from the two first bending sections 191. It is not difficult to see that the clamping and fixing of the annular structure 201 by the two first bending sections 191 can increase the clamping and positioning effect of the annular structure 201. In addition, the structure of the corresponding reinforcement part 100, such as Fig.18 , Fig.19 and Fig. 20As shown, the first support portion 17 includes: a straight section 171, an inclined section 172 and a curved section 173. The straight section 171 is connected to the head end 161 of the connecting portion 16, and the curved section 173 is connected to one of the first bending sections 191. Finally, the inclined section 172 is arranged between the straight section 171 and the curved section 173, and is respectively connected to the straight section 171 and the curved section 173, so that the connecting section 1002 is coaxially arranged with the second bending section 101. Therefore, when the two first bending sections 191 and the second bending section 101 are clamping the annular structure 201, as shown in FIG. Fig.19 and Fig. 20 As shown, the clamping force can be evenly distributed on the annular structure 201, thereby improving the positioning effect of the annular structure 201, so that during the electroplating process of the chain 20, the annular structures 201 will not move, ensuring the uniformity of the electroplating of the inner side surface 2011 of each annular structure 201.

[0084] Those skilled in the art will appreciate that the above-mentioned embodiments are specific embodiments for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
