Description

Technical Field

[0001] This application relates to the field of electroplating equipment technology, and in particular to an electroplating steel strip and electroplating equipment. Background Technology

[0002] Electroplated steel strips serve to hold products and conduct current. The steel strip conducts current through contact with the copper block. Most steel strips currently used on the market are ordinary stainless steel strips. During the electroplating process, both the steel clamp and the clamping parts of the steel strip are plated with a tin layer. This tin layer is removed by strip plating. In related technologies, the part of the steel strip immersed in the plating solution is plated with tin, requiring separate stripping and increasing the consumption of tin balls and chemicals during the electroplating process. Ordinary steel strips have strict requirements for controlling the electroplating solution level and there is a risk of the tin layer on the steel strip peeling off, affecting product yield.

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0036] The following is in conjunction with the appendix Figures 1 to 8 The present application provides a detailed description of some embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Reference Figure 1 and combine when necessary Figures 2 to 8 As shown, this application provides an electroplated steel strip 100, which can be used to carry products in an electroplating process and can move the products. Furthermore, when carrying products for electroplating, the electroplated steel strip 100 can also conduct current to the carried products, so that the products move in the electroplating solution and achieve electroplating.

[0038] The electroplated steel strip 100 may include a steel strip body 10, a conductive connection part 20, a product fixing part 30, and an insulating part 40.

[0039] The steel strip body 10 has a first edge 101 and a second edge 102 that are opposite each other in a first direction L.

[0040] The conductive connection portion 20 is disposed on the first edge 101 of the steel strip body 10 and is connected to the steel strip body 10.

[0041] The product fixing part 30 is provided on the steel strip body 10 and can cooperate with the conductive connection part 20 to fix the product.

[0042] The insulating portion 40 covers a portion of the outer surface of the conductive connection portion 20; wherein the conductive connection portion 20, from the exposed portion of the insulating portion 40, contacts the product. For example... Figure 3 As shown, the product can make contact with the conductive connection part 202 exposed from the insulating part 40 to conduct electricity.

[0043] Combination Figure 8As shown, when the electroplated steel strip 100 carries the product and is electroplated in the electroplating solution, the first edge 101 of the steel strip body 10 faces downwards, the second edge 102 is located above the first edge 101, and the surface of the electroplating solution can be located below the first edge 101 of the steel strip body 10, for example... Figure 1 and Figure 8 The dashed line indicates the position at 200.

[0044] In some embodiments, the insulating portion 40 may be made of plastic, such as polyethylene, polypropylene, polyvinyl chloride, polytetrafluoroethylene, etc. Of course, the insulating portion 40 may also be made of other insulating materials capable of covering the conductive connection portion; this application does not limit this choice.

[0045] In some embodiments, the height h of the insulating part 40 is 10mm-15mm, which facilitates the control of the height of the electroplated steel strip 100 in the electroplating solution and reduces the height control accuracy.

[0046] In some embodiments, the electroplated steel strip 100 includes a plurality of conductive connection portions 20, which are spaced apart at the first edge 101 of the steel strip body 10. That is, the plurality of conductive connection portions 20 are spaced apart in the second direction W and are all connected to the first edge 101 of the steel strip body 10.

[0047] The second direction W can be perpendicular to the first direction L, or form other non-zero angles.

[0048] In some embodiments, each of the conductive connection portions 20 is covered with an insulating portion 40.

[0049] In other embodiments, the conductive connection may be partially covered by an insulating portion.

[0050] Of course, in some other embodiments, the conductive connection portion 20 of the electroplated steel strip 100 may also be a non-interval structure, that is, a continuous structure in the second direction W, such as a structure that extends downward along the steel strip body 10 and is connected together.

[0051] In some embodiments, the conductive connection portion 20 includes a connection body 21 and a product contact portion 22. The connection body 21 is connected to the first edge 101 of the steel strip body 10. The product contact portion 22 is located on the side of the connection body 21 away from the first edge 101. The product contact portion 22 is exposed from the insulating portion 40 to make contact with the product to achieve conductivity.

[0052] The insulating portion 40 covers at least a portion of the connecting body 21.

[0053] In some embodiments, the height of the product contact portion 22 is less than the height of the connecting body 21.

[0054] In some embodiments, the height of the product contact portion 22 may be approximately 1 mm.

[0055] Combination Figure 2 and Figure 7 and Figure 8 As shown, in some embodiments, the insulating portion 40 covers the entire area of ​​the connecting body 21, that is, it covers the entire exposed area of ​​the connecting body 21.

[0056] Of course, in other embodiments, the insulating portion may only cover a portion of the connecting body.

[0057] In some embodiments, the insulating portion 40 also covers a portion of the first edge 101 of the steel strip body 10 to prevent the steel strip body 10 from being electroplated with plating material during electroplating.

[0058] The portion of the insulating part 40 covering the first edge 101 of the steel strip body 10 can be understood as covering a portion of the height of the first edge 101. For example... Figure 8 The portion of the first edge 101 of the steel strip body 10 shown has a height d, which is greater than 0. This height d can be set as needed. For example, it can be 3.5-5.5 mm, such as 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, etc.

[0059] Combination Figure 8 As shown, when the electroplated steel strip 100 carries the product in the electroplating solution for electroplating, it is more conducive to ensuring that the steel strip body 10 does not come into contact with the electroplating solution.

[0060] Of course, in some other embodiments, the insulating portion 40 may not cover the first edge 101 of the steel strip body 10.

[0061] In some embodiments, the first edge 101 of the steel strip body 10 is provided with a fixing hole 1003 opposite to each conductive connection portion 20, and a portion of the insulating portion 40 is disposed in the fixing hole 1003.

[0062] This design helps to ensure that the insulation part 40 is set more stably and is less likely to fall off.

[0063] In some embodiments, the insulating portion 40 is an injection-molded part manufactured using an injection molding process.

[0064] In some embodiments, the conductive connection portion 20 is integrally formed with the steel strip body 10, which is beneficial to the preparation of the steel strip body 10 and the conductive connection portion 20.

[0065] Accordingly, the conductive part 20 and the steel strip body 10 are made of the same material.

[0066] Of course, in some other embodiments, the conductive connection portion may also be prepared separately from the steel strip body and then fixedly connected together.

[0067] In some embodiments, the product fixing part 30 is a clamping member 301. The clamping member 301 has a clamping part 32. The clamping member 301 has a clamped state and an open state; wherein, when the clamping member 301 is in the clamped state, the clamping part 32 can clamp and cooperate with the conductive connection part 20 to fix the product. When the clamping member 301 is in the open state, the clamping part 32 can be separated from the conductive connection part 20, the product can be separated from the electroplated steel strip 100, or the product can be placed on the electroplated steel strip 100 for further fixation by the clamping member 301.

[0068] Combination Figures 2 to 6 As shown, in some embodiments, the steel strip body 10 has a first surface S1 and a second surface S2 that are opposite to each other. A clamping mating hole 201 is provided in the central region of the conductive connection portion 20. The clamping member 301 includes an elastic main body portion 31 and a clamping connection portion 33 connecting the elastic main body portion 31 and the clamping portion 32.

[0069] The elastic main body 31 is located on the side of the first surface S1 of the steel strip body 10, the clamping connection part 33 passes through the clamping mating hole 201, and the clamping part 32 is located on the side of the second surface S2 of the steel strip body 10 and is opposite to the conductive connection part 20.

[0070] Combination Figure 4 As shown, when the clamping member 301 is in the clamping state, the elastic main body 31 provides a clamping force to the clamping part 32 through the clamping connection part 33, so that the clamping part 32 is clamped and engaged with the opposite conductive connection part 20.

[0071] It is understood that the clamping force can be a force acting along the second surface S2 toward the first surface S1. When the clamping member 301 is installed on the steel strip body 10, without external force, the elastic main body 31 of the clamping member 301 can provide a force such as... Figure 4 The force F1 shown causes the clamping connection 33 to drive the clamping part 32 to move in the direction shown by the force F1, so that the clamping part 32 abuts against the conductive connection 20 and achieves clamping cooperation with the conductive connection 20.

[0072] It should be noted that, Figure 4This illustration only shows the clamping state of the clamping member 301 when no product is being fixed. When a product is being fixed, the part of the product to be fixed can be clamped between the clamping part 32 and the conductive connection part 20 when the clamping member 301 is in the clamping state, and the product contacts the exposed part of the conductive connection part 20 (i.e., the product contact part 22).

[0073] Combination Figure 5 As shown, when the clamping part is in the open state, the clamping part 32 is subjected to a loosening force opposite to the clamping force and is separated from the conductive connection part 20.

[0074] The loosening force can be a force acting along the first surface S1 towards the second surface S2. An external force can be applied to the clamping connection 33 as follows: Figure 5 The force F shown causes the clamping connection 33 to drive the clamping part 32 to move in the direction shown by the force F, thereby separating the clamping part 32 from the conductive connection 20, and creating a gap space 103 between the clamping part 32 and the conductive connection 20.

[0075] It should be noted that, in combination Figure 4 and Figure 5 As shown, in some embodiments, the product contact portion 22 protrudes from the side opposite to the first surface S1 relative to the second surface S2 of the steel strip body 10, so that when the clamping portion 32 clamps the product, the product contacts the product contact portion 22, thereby realizing the electrical connection between the product and the product contact portion 22.

[0076] In some embodiments, the clamping member 301 is an integral structure. For example, the elastic main body 31, the clamping connection 33, and the clamping part 32 are an integral structure.

[0077] Combination Figures 4 to 6 As shown, in some embodiments, the clamping member 301 may be a torsion spring. The elastic main body 31 is a torsion spring body.

[0078] Combination Figure 2 As shown, in some embodiments, at least part of the clamping member 301 includes two opposing clamping portions 32, which respectively cooperate with two adjacent conductive connection portions 20.

[0079] It should be noted that in some other embodiments, the product fixing part can also be other fixing structures, such as a locking fixing structure.

[0080] In some embodiments, the steel strip body 10 may also be provided with an installation part for mounting the product fixing part 30.

[0081] In some embodiments, the steel strip body 10 is provided with a mounting hole 1001, which serves as a mounting part for mounting the product fixing part 30, such as fixing the clamping member 301.

[0082] Combination Figures 2 to 6 As shown, taking the clamping member 301, which includes an elastic main body 31, a clamping connecting part 33, and a clamping part 32, as an example, the clamping member 301 may further include a fixing limiting part 35 and a fixing connecting part 34. One end of the fixing connecting part 34 is connected to the elastic main body 31, and the other end is connected to the fixing limiting part 35. The fixing connecting part 34 passes through the mounting hole 1001, and the fixing limiting part 35 is located on the side where the second surface S2 of the steel strip body 10 is located, and abuts against the second surface S2 of the steel strip body 10. The elastic main body 31 provides a corresponding force through the fixing connecting part 34, causing the fixing limiting part 35 to abut against the second surface S2 of the steel strip body 10.

[0083] It is understood that both the clamping part 32 and the fixing and limiting part 35 are located on the side of the second surface of the steel strip body 10. The clamping part 32 can cooperate with the fixing and limiting part 35 to fix the clamping member 301. With this configuration, compared with the use of clamping members and other non-mounting hole methods, the structure of the clamping member is simple, and no additional structure is needed to install the clamping member, making the installation of the clamping member 301 simple and convenient.

[0084] Accordingly, in some embodiments, the elastic main body 31, the clamping connection 33, the clamping part 32, the fixing limiting part 35, and the fixing connection 34 may be an integral structure.

[0085] In other embodiments, the mounting portion can also be other structures capable of fixing the corresponding clamping member. The specific structure of the mounting portion can be configured as needed.

[0086] In some embodiments, the steel strip body 10 may also be provided with holes 1002 to ensure the toughness of the steel strip.

[0087] Combination Figure 4 and Figure 5 Based on the above description, when using the electroplated steel strip 100 to carry the product, a clamping connection 33 can be provided with a... Figure 5 The force F applied causes the clamping member 301 to be in the open state, and places the part of the product to be fixed in the space 103 between the corresponding clamping part 32 and the conductive connection part 20. Then, the force F applied to the clamping connection part 33 is removed, and under the action of the elastic main body part 31, the clamping connection part 33 clamps and engages with the corresponding conductive connection part 20, thus fixing the part of the product to be fixed by the clamping part 32 and the corresponding conductive connection part 20.

[0088] It should be noted that for products with multiple clamping members 301, forces can be applied to the multiple clamping members 301 along the W direction to sequentially fix or release the product to be fixed.

[0089] This application also provides an electroplating apparatus. The electroplating apparatus may include the electroplating steel strip as described above. The electroplating apparatus may further include an electroplating solution tank and a driving device. The electroplating solution tank may contain an electroplating solution. The electroplating steel strip may be mounted on the driving device. The driving device may drive the electroplating steel strip to move, thereby moving the product carried by the electroplating steel strip into the electroplating solution tank to achieve electroplating of the product, and, upon completion of product electroplating, drive the electroplating steel strip to remove the electroplated product from the electroplating solution tank.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
