[0026] To make the above objects, features and advantages of the present application more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0027] As Figure 1 and Figure 2As shown, in one embodiment, a pre-plated wire winding device 10 is provided, which includes a tank body 100 and a wire winding assembly 200. Among them, the tank body 100 is provided with a pre-plating tank 101, an inlet wire groove 102 and an outlet wire groove 103 respectively located on opposite sides of the pre-plating tank 101, a first wire slit 104 for connecting the inlet wire groove 102 and the pre-plating tank 101, and a second wire slit 105 for connecting the pre-plating tank 101 and the outlet wire groove 103. The wire winding assembly 200 includes a first conductive member 210 and a first wire winding member 220 that are rotatably installed in the inlet wire groove 102, and a second conductive member 230 and a second wire winding member 240 that are rotatably installed in the outlet wire groove 103. The first conductive member 210, the first wire winding member 220, the second conductive member 230 and the second wire winding member 240 are all used for winding the pre-plated wire 20 so that the pre-plated wire 20 passes through the pre-plating tank 101 multiple times.

[0028] For the pre-plated wire winding device 10 in the above embodiment, during use, the pre-plated wire 20 is correspondingly wound around the first conductive member 210, the first wire winding member 220, the second conductive member 230 and the second wire winding member 240, so that the first wire winding member 220 and the second wire winding member 240 can adjust the direction of the pre-plated wire 20, and the first conductive member 210 and the second conductive member 230 can guide and limit the pre-plated wire 20. The pre-plated wire 20 folds back and forth between the first wire winding member 220 and the second wire winding member 240, and passes through the pre-plating tank 101 multiple times from the first wire slit 104 and the second wire slit 105, completing the assembly of the pre-plated wire 20 and the pre-plated wire winding device 10. In the pre-plated wire winding device 10 of the present application, by reasonably designing the winding method of the pre-plated wire 20, the plating area of the pre-plated wire 20 and the contact time between the pre-plated wire 20 and the plating solution in the pre-plating tank 101 are greatly increased. It is ensured that when the production line speed of the pre-plated wire 20 is greatly increased, there is no hidden danger of excessive cathode current density and blackening of the conductive rod. A thicker and higher-quality coating can be plated on the pre-plated wire 20. In addition, the pre-plated wire winding device 10 in the present application can correspondingly adjust the winding method of the pre-plated wire 20 on the basis of the existing equipment, without lengthening the length of the pre-plating tank 101, nor increasing the number of pre-plating tanks 101 and the number of large rollers. The demand for plating solution and nickel beads is small, and the cost is low.

[0029] Among them, both the first conductive member 210 and the second conductive member 230 can be configured as conductive rods, conductive bars or other conductive structures. Both the first winding member 220 and the second conductive member 230 can be configured as winding rods, winding wheels or other winding structures. Specifically in this embodiment, bearings that can rotate flexibly and bearing seats for installing the bearings are connected to both ends of the first conductive member 210, both ends of the first winding member 220, both ends of the second conductive member 230, and both ends of the second winding member 240. Each bearing seat is fixedly installed in the inlet wire groove 102 and the outlet wire groove 103 respectively. In this way, during normal production, the movement of the pre-plated wire 20 can easily drive the first conductive member 210, the first winding member 220, the second conductive member 230 and the second winding member 240 to rotate, improving the reliability of the pre-plated winding device 10.

[0030] It should be noted that when the pre-plated wire 20 turns back and winds, it is wound on the same side of the first conductive member 210 and the same side of the second conductive member 230. Since the plating area of the pre-plated wire 20 increases and the coating layer is generally not more than 0.5 um, according to the formula "coating layer thickness (um)=current density (ASF)*electroplating time (min)*electroplating efficiency*0.0182", it can be known that the current density of the pre-plated wire 20 during electroplating is about 3 A / dm 2 to 8 A / dm 2 , this current density range is not too high, and the porosity of the plated coating layer is low, and the coating layer quality is high. The electroplating solution can be configured as an electroplating solution of a nickel sulfamate system.

[0031] Furthermore, both the first conductive member 210 and the second conductive member 230 are provided with a first winding group. The first winding group includes at least one first winding part spaced along the axis direction of the first conductive member 210. Both the first winding member 220 and the second winding member 240 are provided with a second winding group. The second winding group includes at least one second winding part spaced along the axis direction of the first winding member 220. Each first winding part and each second winding part are used for winding the pre-plated wire 20, so that the pre-plated wire 20 passes through the pre-plating tank 101 multiple times. In this way, both the first winding part and the second winding part can play a guiding and limiting role on the pre-plated wire 20, ensuring that the pre-plated wire 20 will not interfere and wind with each other during the movement process, and improving the reliability of the pre-plated winding device 10.

[0032] Optionally, the first winding part is configured as a first annular groove. The second winding part is configured as a second annular groove. Specifically in this embodiment, along the direction perpendicular to the axis of the first annular groove, the cross-section of the first annular groove is configured as a U shape. Along the direction perpendicular to the axis of the second annular groove, the cross-section of the second annular groove is configured as a U shape.

[0033] Among them, the width of the first annular groove, the width of the second annular groove, the distance between two adjacent first annular grooves, and the distance between two adjacent second annular grooves can all be flexibly adjusted according to actual usage requirements. Specifically in this embodiment, the outer diameter of the first conductive member 210 is 40 mm, and along the axial direction of the first conductive member 210, the distance between the central planes of two adjacent first annular grooves is 3.98 mm.

[0034] Optionally, the number of the first winding parts in the first winding group is a, and the number of the second winding parts in the second winding group is b, where a = 2b + 1. In this way, the pre-plated wire 20 can be wound back and forth b times and pass through the pre-plating tank 101 a times.

[0035] Among them, the values of a and the value of b can both be flexibly adjusted according to actual usage requirements.

[0036] It should be noted that during the actual processing, in order to improve the convenience of processing the second winding part and the convenience of winding, the actual number of the second winding parts in the second winding group will be greater than b.

[0037] Optionally, both the first winding member 220 and the second winding member 240 include a core rod and a nylon circular tube wrapped around the outer wall of the core rod, and each second winding part is arranged at intervals along the axial direction of the core rod on the outer wall of the nylon circular tube. In this way, the nylon circular tube has good wear resistance, increasing the reliability of the first winding member 220 and the second winding member 240 and improving the service life of the pre-plating winding device 10.

[0038] Specifically in this embodiment, the core rod, the first conductive member 210, and the second conductive member 230 are all made of 304 stainless steel.

[0039] In one embodiment, there are at least two first winding groups, and each first winding group on the first conductive member 210 is arranged at intervals along the axial direction of the first conductive member 210, each first winding group on the second conductive member 230 is arranged at intervals along the axial direction of the second conductive member 230, there are at least two second winding groups, each second winding group on the first winding member 220 is arranged at intervals along the axial direction of the first winding member 220, each second winding group on the second winding member 240 is arranged at intervals along the axial direction of the second winding member 240, and each first winding group and each second winding group are arranged in one-to-one correspondence. In this way, the pre-plating winding device 10 can wind multiple pre-plated wires 20 simultaneously for production, improving the practicability of the pre-plating winding device 10.

[0040] Among them, the number of the first winding groups and the number of the second winding groups can both be adjusted according to actual usage requirements. For example, the number of the first winding groups on the first conductive member 210 and the number of the second winding groups on the second conductive member 230 can both be 12 or 16, etc.

[0041] Specifically in this embodiment, the structural shape and size of the second conductive member 230 are the same as those of the first conductive member 210. All the first winding portions on the first conductive member 210 are uniformly and spaced along the axial direction of the first conductive member 210. The structural shape and size of the second winding member 240 are the same as those of the first winding member 220. All the second winding portions on the first winding member 220 are uniformly and spaced along the axial direction of the first winding member 220.

[0042] Such as Figure 1 , Figure 2 and Figure 3 As shown in , in one embodiment, the trough body 100 includes a trough main body 106, a first liquid baffle 108 provided with a third slit 107, a second liquid baffle 109 provided with a first slit 104, a third liquid baffle 110 provided with a second slit 105, and a fourth liquid baffle 111 provided with a fourth slit 112. The first liquid baffle 108, the second liquid baffle 109, the third liquid baffle 110, and the fourth liquid baffle 111 are all spaced in the trough main body 106 to divide the inner cavity of the trough main body 106 into a sequentially arranged wire inlet trough 102, a first return trough 113, a pre - plating trough 101, a second return trough 114, and a wire outlet trough 103. The first slit 104 communicates the wire inlet trough 102 and the first return trough 113, the second slit 105 communicates the first return trough 113 and the pre - plating trough 101, the third slit 107 communicates the pre - plating trough 101 and the second return trough 114, and the fourth slit 112 communicates the second return trough 114 and the wire outlet trough 103. Thus, the first liquid baffle 108 can block the electroplating solution leaking at the first slit 104 from flowing into the wire inlet trough 102, ensuring that the first conductive member 210 and the first winding member 220 can rotate smoothly. The second liquid baffle 109 can block the electroplating solution leaking at the second slit 105 from flowing into the wire outlet trough 103, ensuring that the second conductive member 230 and the second winding member 240 can rotate smoothly, improving the reliability of the pre - plating winding device 10.

[0043] Such as Figure 1 and Figure 3 As shown in , in one embodiment, the top of the first conductive member 210, the first slit 104, the top of the second conductive member 230, and the second slit 105 are all in the same plane. The first winding member 220 is located on the side of the first conductive member 210 away from the pre - plating trough 101 and below the first conductive member 210. The second winding member 240 is located on the side of the second conductive member 230 away from the pre - plating trough 101 and below the second conductive member 230. Thus, the limited space in the wire inlet trough 102 and the wire outlet trough 103 is fully utilized, making the total length of the trough body 100 smaller and improving the practicability of the pre - plating winding device 10.

[0044] In other embodiments, the bottom of the first conductive member 210, the first wire seam 104, the bottom of the second conductive member 230, and the second wire seam 105 are all located in the same plane. The first winding member 220 is located on the side of the first conductive member 210 away from the pre-plating tank 101 and above the first conductive member 210, and the second winding member 240 is located on the side of the second conductive member 230 away from the pre-plating tank 101 and above the second conductive member 230.

[0045] As Figure 1 shown, specifically in this embodiment, an inlet wire seam 115 is provided on the side of the inlet wire groove 102 away from the pre-plating tank 101. An outlet wire seam 116 is provided on the side of the outlet wire groove 103 away from the pre-plating tank 101. The axial direction of the first conductive member 210, the axial direction of the first winding member 220, the extending direction of the inlet wire seam 115, the extending direction of the first wire seam 104, the extending direction of the second wire seam 105, the extending direction of the third wire seam 107, the extending direction of the fourth wire seam 112, the extending direction of the outlet wire seam 116, the axial direction of the second conductive member 230, and the axial direction of the second winding member 240 are all the same. The top of the first winding portion, the inlet wire seam 115, the first wire seam 104, the second wire seam 105, the third wire seam 107, the fourth wire seam 112, the outlet wire seam 116, and the top of the second winding portion are all located in the same plane.

[0046] As Figure 1 and Figure 3 shown, in one embodiment, both the inlet wire groove 102 and the outlet wire groove 103 are provided with a reflux port 117. The pre-plating winding device 10 further includes a driving pump provided with an inlet port and an outlet port, a first spray pipe 310 disposed in the inlet wire groove 102 and used for spraying electroplating solution onto the first conductive member 210, and a second spray pipe 320 disposed in the outlet wire groove 103 and used for spraying electroplating solution onto the second conductive member 230. The inlet port is communicated with each reflux port 117, and the outlet port is communicated with the first spray pipe 310 and the second spray pipe 320. In this way, the electroplating solution can be sprayed onto the pre-plating wire 20 wound around the first conductive member 210 and the pre-plating wire 20 wound around the second conductive member 230, improving the practicability of the pre-plating winding device 10.

[0047] Among them, the number of driving pumps can be flexibly adjusted according to actual usage requirements. Specifically in this embodiment, the first spray pipe 310 is installed above the first conductive member 210. The second spray pipe 320 is installed above the second conductive member 230. The first reflux tank 113 and the second reflux tank 114 are also provided with a reflux port 117, and the inlet port is communicated with each reflux port 117.

[0048] To facilitate further understanding of the structure of the pre-plating winding device 10, the following will be described in detail by taking the pre-plating wire 20 as a steel wire, the first conductive member 210 as a first conductive rod, the second conductive member 230 as a second conductive rod, the first winding member 220 as a first winding wheel, the second winding member 240 as a second winding wheel, a single first winding group including 11 first annular grooves, and a single second winding group including 5 second annular grooves as an example, which should not be construed as a limitation on the present application.

[0049] like Figure 1 As shown, the steel wire enters the wire inlet groove 102 from the wire inlet seam 115, passes through the first first annular groove on the first conductive rod, passes through the third wire seam 107, the first reflux groove 113 and the first wire seam 104 in sequence, enters the pre-plating tank 101 and is immersed in the electroplating solution, then exits the second wire seam 105, passes through the second liquid reflux groove and the fourth wire seam 112, and enters the wire outlet groove 103. In the wire outlet groove 103, after passing through the first first annular groove on the second conductive rod, it moves diagonally to the lower right, circles the first second annular groove on the second wire guide wheel clockwise, and then moves diagonally to the upper left, passes through the second first annular groove on the second conductive rod, and then moves horizontally to the left, passes through the fourth wire seam 112, the second reflux groove 114, the second wire seam 105, the pre-plating tank 101, the first wire seam 104, the first reflux groove 113 and the third wire seam 107 in sequence, and re-enters the wire inlet groove 102. In the wire inlet groove 102, after passing through the second first annular groove on the first conductive rod, it moves diagonally to the lower left, and after making a counterclockwise circle around the first second annular groove on the first winding guide wheel, it moves diagonally to the upper right, passes through the third first annular groove on the first conductive rod, and then moves horizontally to the right, passing through the third wire seam 107, the first reflow groove 113, the first wire seam 104, the pre-plating groove 101, the second wire seam 105, the second reflow groove 114 and the fourth wire seam 112 in sequence and re-enters the wire return groove. In the return groove, after passing through the third first annular groove on the second conductive rod, it moves diagonally to the lower right, and after clockwise winding around the second second annular groove on the second winding guide wheel, it moves diagonally to the upper left, and after passing through the fourth first annular groove on the second conductive rod, it moves further horizontally to the left, and turns back and forth five times. After 11 sections of the steel wire have been immersed in the electroplating solution in the pre-plating tank 101, the steel wire no longer turns back from the outlet groove 103, but exits the entire pre-plating process from the outlet seam 116 and enters the next process. In this way, the plated area of the steel wire is 11 times the original plated area, and even if the production speed of the electroplated gold steel wire reaches 60m / min to 80m / min, there is no risk of excessive cathode current density and burning of the conductive rod.

[0050] In one embodiment, a production device for electroplated diamond wire is provided, comprising the pre-plating winding device 10 in any one of the above embodiments.

[0051] In the electroplated diamond wire production equipment in the above embodiments, during use, the pre-plated wire 20 is correspondingly wound around the first conductive member 210, the first wire winding member 220, the second conductive member 230, and the second wire winding member 240, such that the first wire winding member 220 and the second wire winding member 240 can adjust the direction of the pre-plated wire 20, and the first conductive member 210 and the second conductive member 230 can guide and limit the pre-plated wire 20. The pre-plated wire 20 turns back and forth between the first wire winding member 220 and the second wire winding member 240, and passes through the pre-plating tank 101 multiple times from the first wire slot 104 and the second wire slot 105, completing the assembly of the pre-plated wire 20 and the pre-plating wire winding device 10. In the pre-plating wire winding device 10 of the present application, by reasonably designing the winding method of the pre-plated wire 20, the plating area of the pre-plated wire 20 and the contact time between the pre-plated wire 20 and the plating solution in the pre-plating tank 101 are greatly increased, ensuring that there is no hidden danger of excessive cathode current density and blackening of the conductive rod when the production line speed of the pre-plated wire 20 is greatly increased, and a thicker and higher-quality coating can be plated on the pre-plated wire 20. In addition, the pre-plating wire winding device 10 in the present application can correspondingly adjust the winding method of the pre-plated wire 20 on the basis of the existing equipment, without lengthening the length of the pre-plating tank 101, nor increasing the number of pre-plating tanks 101 and the number of large rollers. The demand for plating solution and nickel beads is small, and the cost is low.

[0052] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application 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 thus cannot be understood as a limitation to the present application.

[0053] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there is a term "plural", the meaning of "plural" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0054] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0056] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0057] It should also be understood that when interpreting the connection relationship or position relationship of elements, although not clearly described, the connection relationship and position relationship are interpreted to include the error range, and this error range should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "about", "approximately" or "substantially" can mean within one or more standard deviations, which is not limited here.

[0058] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0059] The above embodiments only represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several variations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
