Description

Technical Field

[0001] The present application belongs to the technical field of electroplating equipment, and in particular relates to a narrow-edge electroplating brush head. Background Art

[0002] A brush plating machine is a surface treatment device used to apply a metal or alloy coating to a workpiece through brush plating. Utilizing electrochemical principles, a solution containing the desired metal ions acts as an electrolyte. A specially designed plating brush contacts the workpiece surface. Under the influence of an electric field, the metal ions undergo a reduction reaction on the workpiece surface, depositing a metal coating. During the brush plating process, the brush and workpiece maintain relative motion to ensure uniform coating distribution.

[0003] Electroplating brush heads are typically rectangular strips, wider than the strip of metal sheet material, and pre-coated with plating solution on their top surface. However, conventional electroplating brush heads have a relatively thick plating tip. During electroplating, the brush head and the workpiece in contact are relatively large, resulting in a large plating area. This can easily lead to uneven plating on small workpieces or plating beyond the intended area, resulting in a high rate of defective workpieces. This also results in a rapid depletion of electroplating consumables.

[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Utility Model Content

The pointed cone portion is provided with a plurality of spray holes for spraying the electroplating liquid, and the pointed cone portion is used for electroplating the workpiece;

[0009] and a pumping assembly, the pumping assembly being used to pump the electroplating liquid in the electroplating liquid containing tank to the pointed cone portion through the spray hole;

In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0030] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0031] The utility model provides Figure 1、 Figure 2 As shown, a narrow-edge electroplating brush head is an important structural component of the electroplating brush plating machine, which is used to accommodate the electroplating liquid and electroplate the electroplating liquid to the part to be plated of the workpiece; the main structure of the utility model includes: an electroplating liquid accommodating box 1, an electroplating liquid brush head 2 and a pumping component 3, the electroplating liquid accommodating box 1 is provided with an electroplating liquid accommodating tank 11, and the electroplating liquid accommodating tank 11 is used to accommodate the electroplating liquid; the electroplating liquid brush head 2 is arranged in the plating liquid accommodating tank 11, and the electroplating liquid brush head 2 is a long strip structure. The two sides of the head 2 are brought together to form two inclined surfaces 21, and the intersection of the two inclined surfaces 21 forms a pointed cone 22. The pointed cone 22 extends along the extension direction of the electroplating liquid brush head 2. A number of spray holes 23 are provided on the pointed cone 22. The spray holes 23 are used to spray the electroplating liquid, and the pointed cone 22 is used to electroplate the workpiece; the pumping component 3 is used to pump the electroplating liquid in the electroplating liquid holding tank 11 to the pointed cone 22 through the spray holes 23; wherein, the angle between the two inclined surfaces 21 is less than or equal to 16°.

[0032] It should be noted that the plating end of a conventional electroplating brush head (electroplating liquid brush head 2) is relatively thick. During electroplating, the contact area between the electroplating brush head (electroplating liquid brush head 2) and the workpiece to be electroplated is relatively large, resulting in a relatively large electroplating area. This can easily cause uneven electroplating on small workpieces or technical problems such as plating outside the intended area of ​​the workpiece, resulting in a high defective rate of workpiece electroplating. It can also lead to a rapid consumption of electroplating consumables.

[0033] By controlling the angle between the two inclined surfaces 21 to be less than or equal to 16°, the present invention can effectively reduce the thickness of the tapered portion 22, thereby enabling the technical effect of fine electroplating of small workpieces without causing the electroplating to exceed the predetermined electroplating area of ​​the workpiece. Furthermore, it can effectively save electroplating consumables and reduce production costs.

[0034] During use, the workpieces to be electroplated are first arranged and fixed on the workpiece fixing base, and then the electrodes are connected to the electroplating liquid container 1 or the electroplating liquid brush head 2, and the workpieces are also connected to another electrode. The arranged workpieces to be electroplated are placed close to the top of the pointed cone 22 of the electroplating liquid brush head 2, so that the part to be electroplated of the workpiece contacts the top of the pointed cone 22, thereby achieving the technical effect of electroplating the part to be electroplated of the workpiece. Since the top of the pointed cone 22 is thin enough, it can electroplate small workpieces without exceeding the non-electroplating area of ​​the workpiece, effectively saving electroplating consumables and improving electroplating efficiency.

[0035] It is understood that the plating liquid brush head 2 has several pipeline channels internally defined. One end of each channel is connected to the nozzle holes 23 distributed on the tapered portion 22, and the other end is connected to the output pipeline of the pumping assembly 3. In some embodiments, the plating liquid brush head 2 is provided with an input port for the pipeline channel at both ends of its extension direction. The nozzle holes 23 located in the front half of the tapered portion 22 communicate with the pipeline channel at the front end of the plating liquid brush head 2; the nozzle holes 23 located in the rear half of the tapered portion 22 communicate with the pipeline channel input port at the rear end of the plating liquid brush head 2. This ensures that the multiple nozzle holes 23 located in different positions can achieve a relatively balanced plating liquid pumping pressure.

[0036] Further, such as Figure 3 、 Figure 4 As shown, a plurality of notches 24 are formed at equal intervals on the pointed cone portion 22 , each of which contains a spray hole 23 , which is connected to a pipeline of the pumping assembly 3 .

[0037] Further, such as Figure 3 、 Figure 4 As shown, the spray hole 23 is arranged at the bottom of the notch 24, and the opening of the spray hole 23 is arranged upward. In some embodiments, the opening of the spray hole 23 is arranged vertically upward.

[0038] Furthermore, the plating liquid container 1 and the plating liquid brush head 2 are both made of metal materials, and the plating liquid brush head 2 is a titanium alloy brush head. It is understandable that the metal material structure can be conductive, and on the basis of satisfying the electrical connection of the entire plating liquid brush head 2, it can also meet the long-term stable operation of the electroplating device. In addition, configuring the plating liquid brush head 2 as a titanium alloy brush head can ensure the structural strength of the plating liquid brush head 2, especially the structural strength of the pointed cone portion 22 on the plating liquid brush head 2, to avoid wear and tear when it is in frictional contact with the workpiece to be electroplated for a long time and multiple times. The service life of the pointed cone portion 22 is improved.

[0039] Further, such as Figure 2 、 Figure 3 As shown, the two inclined surfaces 21 have the same inclination angle. It is understandable that configuring the two inclined surfaces 21 to have the same inclination angle can keep the two sides of the tapered portion 22 balanced, so that the electroplating solution on the top is evenly distributed, and the electroplating effect of the workpiece can be more uniform.

[0040] Further, such as Figure 3 、 Figure 4 As shown, the upper end of the tapered portion 22 is an arc-shaped convex structure. It is understandable that the arc-shaped convex surface can make the plating solution evenly distributed and prevent the upper end of the tapered portion 22 from being too sharp and causing cuts to the workpiece.

[0041] Furthermore, a storage basket 12 is provided in the electroplating solution containing tank 11, and the storage basket 12 is used to place the metal electroplating balls.

[0042] Furthermore, the storage basket 12 can be detachably connected to the electroplating solution containing tank 11 .

[0043] Further, such as Figure 2 、 Figure 3 As shown, a mounting base 4 is provided at the bottom of the plating liquid brush head 2, and the plating liquid brush head 2 is fixed in the plating liquid containing tank 11 through the mounting base 4. In some embodiments, the mounting base 4 is a metal mounting base 4 so that the plating liquid containing tank 1 and the plating liquid brush head 2 can achieve a conductive effect.

[0044] In summary, this application provides a narrow-edge electroplating brush head. By controlling the angle between the two inclined surfaces 21 to be less than or equal to 16°, the utility model can effectively reduce the thickness of the tapered portion 22, thereby enabling the technical effect of fine electroplating of small workpieces. It can also effectively save electroplating consumables and reduce production costs.

[0045] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
