Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed, but merely represents the selected embodiments of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] Refer to the following Figures 1 to 12 The invention describes an apparatus for copper wire etching according to some embodiments of the present application.

[0041] See also Figures 1 to 7 As shown, an embodiment of the present application provides a device for copper wire etching, comprising: a winding member 1 and a pressing member; wherein the winding member 1 is provided with a plurality of tooth grooves 11 at the top and bottom ends thereof along the height direction, and the plurality of tooth grooves 11 at the same end are sequentially arranged along the length direction of the winding member 1, and are used for winding and fixing the copper wire. Under normal circumstances, a copper wire is generally sequentially wound through the tooth grooves 11 at the top and bottom of the winding member 1;

[0042] The pressing member is installed on the large side 15 of the winding member 1 for winding the copper wire, and is used to press the copper wire wound on the winding member 1. Here, the large side 15 of the winding member 1 specifically refers to the side formed by its long side and high side.

[0043] When the copper wire is cut to extract a portion for use, the extracted portion of the copper wire can be removed from between the pressing member and the large surface side 15 of the winding member 1 .

[0044] Based on the structure described above, it can be known that when the device for copper wire etching provided by the present application is used, the copper wire can be wound around the winding member 1 in sequence, and fixed through the tooth grooves 11 at the top and bottom. The operation is simple and convenient, and the production efficiency is high. Moreover, since the copper wire does not need to be fixed by gluing, the copper wire will not be entangled due to the fall of the glue after being immersed in a strong acid melt. That is to say, after the copper wire is wound and fixed by the device for copper wire etching and immersed in strong acid, adjacent copper wires will not be entangled together and remain distinct, thereby ensuring the uniformity of etching, and the immersion area is clear, which is convenient for later use. In addition, after immersion, the winding member 1 and the copper wire only need to be taken out as a whole and rinsed with water. The operation is relatively convenient and the use safety is high.

[0045] In this embodiment, preferably, the pressing member is an elastic rubber ring (not shown in the figure), and the elastic rubber ring can be detachably sleeved on the outer circumference of the winding member 1.

[0046] According to the structure described above, after the copper wire is wound on the winding member 1, the elastic rubber ring is put on the outer periphery of the winding member 1. The elastic rubber ring can press the copper wire tightly. Therefore, when the copper wire needs to be taken, it is only necessary to cut off this part of the copper wire and pull it out from the elastic rubber ring and the large surface side 15 of the winding member 1. The remaining copper wire remains stationary under the fixing effect of the elastic rubber ring, which is convenient for next time use.

[0047] Further, preferably, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the two opposite large surface sides 15 of the winding member 1 are both provided with mounting grooves 14, and the elastic rubber ring can press the copper wire into the mounting grooves 14. It can be seen that the mounting grooves 14 of the two large surface sides 15 are used to limit the elastic rubber ring, so that the elastic rubber ring and the winding member 1 are assembled more stably. Of course, it is not limited to this, and the mounting grooves 14 may not be designed on the winding member 1, that is, the elastic rubber ring is directly sleeved on the outer periphery of the winding member 1, and is fixed by elastic force without designing the aforementioned mounting grooves 14, and the specific design is based on actual needs.

[0048] It should be noted that the structure of the pressing component is not limited to the above-mentioned elastic rubber ring, and it can also adopt the following structure. For example, the pressing component is a rubber strip, and the two opposite large sides 15 of the winding component 1 are both provided with installation grooves 14, and the rubber strip can be detachably installed in any installation groove 14.

[0049] According to the structure described above, the rubber strip can be used to press part of the structure of the copper wire into the installation groove 14, which can better fix the copper wire and the rubber strip, so that the tension on the copper wire is consistent, ensuring that the copper wire at each location is in a taut state, thereby ensuring the consistency of the infiltration.

[0050] In addition, when it is necessary to cut off part of the copper wire for use, the copper wire can be cut off at the top and bottom ends first, and then the part of the rubber strip that presses the copper wire can be lifted up from the installation groove 14 to release the fixing effect on the copper wire, so that the copper wire can be taken away. Of course, the operation sequence is not limited to this. The corresponding part of the rubber strip can also be lifted up from the installation groove 14 first, and then the copper wire can be cut off. The specific design is based on actual needs.

[0051] In this embodiment, preferably, Figure 4 , Figure 8 and Fig. 9 As shown, an etched area 12 is formed at the lower portion of the winding member 1 along the height direction thereof, and along the width direction of the winding member 1 , opposite sides of the etched area 12 are both concave.

[0052] According to the structure described above, the two opposite large etching surfaces 121 of the etching area 12 are both concave, and the aforementioned pressing member ensures that the copper wire is in a taut state, so that a space is formed between the large etching surface 121 of the concave etching area 12 and the taut copper wire, so that the strong acid can flow, thereby ensuring that the copper wire is fully infiltrated, and on the other hand, it can be used as an identification of the etching area 12 to distinguish the upper non-etching area 12. Of course, it is not limited to this, and the winding member 1 can also be made into a structure with the same width at the top and bottom along the height direction, which is specifically designed according to actual needs.

[0053] Further, preferably, along the length direction perpendicular to the winding member 1, the longitudinal section of the etched area 12 is not limited to Fig. 9 The triangle-like shape in the figure can also be other shapes, such as waist drum shape, etc., which can be designed according to actual needs.

[0054] In this embodiment, preferably, Figures 10 to 12 As shown, the device for copper wire etching also includes an immersor 2, which is a structure with a hollow interior and an open top, and is used to place a corrosive liquid, and a portion of the winding member 1 wound with the copper wire can be immersed in the corrosive liquid through the top opening of the immersor 2.

[0055] According to the structure described above, the device for etching copper wire provided in the present application is equipped with a separate immersing device 2, which can be used to place a strong acid solution, and then the lower part of the winding member 1 wound with the copper wire can be extended into it, that is, the etching area 12 is immersed in the acid solution, so as to facilitate the etching of the lower part of the copper wire installed on the winding member 1.

[0056] In this embodiment, preferably, Figure 2 , Fig.11 and Fig.12 As shown, a positioning protrusion 13 is formed on the side of the winding member 1 , and a positioning groove 211 is formed on the side wall of the open end of the macerator 2 , and the positioning protrusion 13 can be installed in the positioning groove 211 .

[0057] According to the structure described above, the positioning protrusion 13 and the positioning groove 211 cooperate with each other to position the winding member 1 and ensure the etching effect.

[0058] In this embodiment, preferably, Figure 4 and Fig.10 As shown, positioning protrusions 13 are formed on both sides of the winding member 1 along the length direction of the winding member 1, that is, positioning protrusions 13 are respectively provided on two opposite small face sides 16 of the winding member 1, where the small face side 16 of the winding member 1 specifically refers to the side formed by its wide side and high side;

[0059] Along the length direction of the opening end of the macerator 2, two opposite side walls of the opening end of the macerator 2 are formed with positioning grooves 211, and the two positioning grooves 211 correspond to the two positioning protrusions 13 one by one.

[0060] According to the structure described above, the two positioning protrusions 13 at both ends of the winding member 1 along its length direction cooperate with the two positioning grooves 211 at the open end of the impregnator 2 to position the winding member 1, which has a better effect.

[0061] Furthermore, preferably, the positioning protrusion 13 is a cylindrical structure, and correspondingly, the positioning groove 211 is a matching arc groove, which has a simple structure, is easy to manufacture, and is easy to assemble later. Of course, it is not limited to this, and the shape of the positioning protrusion can be designed according to actual needs, for example, it can be a prism such as a quadrangular prism, a pentagonal prism or a hexagonal prism, etc.

[0062] It should be noted that the number and installation positions of the positioning protrusions 13 are not limited to the above. For example, positioning protrusions 13 can also be set on the two opposite large surface sides 15 of the winding member 1, and positioning grooves 211 can be opened at corresponding positions of the impregnator 2, which can also play the role of installation positioning.

[0063] In this embodiment, preferably, Fig.10 As shown, the infuser 2 includes a main container 21 and a base 22. The base 22 is arranged at the bottom of the main container 21 along the height direction thereof. The main container 21 is formed with a containing cavity and a top opening.

[0064] According to the structure described above, the base 22 plays a role in supporting the main container 21, making the main container 21 more stable, and the main container 21 plays a role in containing strong acid for etching, and the main container 21 can be designed to be a tall and thin structure to match the winding structure 1, with less consumables itself, and can reduce the amount of acid used in the later etching, that is, save acid, which helps to reduce the cost of etching. The base 22 plays a major supporting role, so it can be designed to be wider, that is, the width of the base 22 is significantly larger than the main container 21, which improves the supporting effect, and the separate design helps to reduce material costs.

[0065] Furthermore, preferably, the main container 21 is a tall and thin rectangular container, and the base 22 is a plate-like structure parallel to the horizontal plane, which is more stable. Of course, the structure of the main container 21 and the base 22 is not limited to this, and can also be designed according to actual needs.

[0066] Further, preferably, the main container 21 and the base 22 are an integrated structure, but of course, this is not limited to this.

[0067] In this embodiment, preferably, the material of the immersion vessel 2 is glass, which is not easy to corrode and is convenient for observing the liquid level of the strong acid and monitoring the etching process. Of course, the material of the immersion vessel 2 is not limited to this, and other corrosion-resistant materials can also be used, and preferably, a transparent and corrosion-resistant material can be selected, and the specific design is based on actual needs.

[0068] In this embodiment, preferably, the material of the winding member 1 is polytetrafluoroethylene, which has excellent chemical corrosion resistance and can resist corrosion by various chemical substances such as acid, alkali, and salt, and does not adhere to the copper wire, so it is suitable for use in the etching process of the copper wire. Of course, the material of the winding member 1 is not limited to this, and other corrosion-resistant materials can also be used, which can be designed according to actual needs.

[0069] In this embodiment, preferably, Figure 1 As shown, the winding member 1 is a plate-like structure, and preferably, it is a rectangular plate-like structure, and its length and height are greater than its width, that is, its thickness, that is, the winding member 1 is a plate with a smaller width, that is, a smaller thickness;

[0070] The inner hollow structure of the impregnator 2 is adapted to fit the wound member 1 .

[0071] According to the structure described above, the winding member 1 adopts a plate-like structure so that the area of ​​the large surface side 15 is large enough to wind a longer steel wire at one time, and its thickness, that is, width, is small, which reduces material costs. Correspondingly, the main container 21 of the impregnator 2 can also be correspondingly designed to be a structure with a narrower width, which also helps to reduce material costs.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
