Description

Technical Field

[0001] The present application belongs to the technical field of electroplating equipment, and in particular relates to a liquid-permeable 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] The plating brush head is usually rectangular and wider than the strip of metal sheet. The top surface of the plating brush head is pre-coated with plating solution. However, when plating metal workpieces, the movement of the workpiece in the plating solution of the plating brush head will interfere with the liquid level of the plating solution, causing the liquid level of the plating solution to fluctuate. The irregular fluctuation of the plating liquid level will cause uneven plating on the metal workpiece (especially some small metal workpieces), resulting in a high defect rate of the workpiece plating.

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

[0009] and a liquid-seeping cloth, which is laid on the upper surface of the electroplating liquid brush head and extends toward the bottom of the electroplating liquid containing tank;

[0010] The seepage cloth sags under the action of gravity at the location of the electroplating chute and contacts the bottom of the electroplating chute. The seepage cloth is used to siphon the electroplating liquid in the electroplating liquid containing tank into the electroplating chute.

[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 liquid-permeable electroplating brush head is an important structural component of an electroplating brush plating machine, which is used to accommodate electroplating liquid and electroplate the electroplating liquid to the part to be plated of the workpiece; the main structure of the utility model includes: a plating liquid accommodating box 1, a plating liquid brush head 2 and a liquid-permeable cloth 3, the plating liquid accommodating box 1 is provided with a plating liquid accommodating tank 11, the plating liquid accommodating tank 11 is used to accommodate the plating liquid; the plating liquid brush head 2 is arranged in the plating liquid accommodating tank 11, and the top surface of the plating liquid brush head 2 is provided with a liquid-permeable cloth 3. There is an electroplating chute 21, which extends along the length of the electroplating liquid brush head 2 and is used to electroplate the workpiece to be electroplated. The seepage cloth 3 is laid on the upper surface of the electroplating liquid brush head 2 and extends toward the bottom of the electroplating liquid storage tank 11. The seepage cloth 3 droops under the action of gravity at the location of the electroplating chute 21 and contacts the bottom of the electroplating chute 21. The seepage cloth 3 is used to siphon the electroplating liquid in the electroplating liquid storage tank 11 into the electroplating chute 21. When in use, the workpiece to be electroplated is first arranged and fixed on the workpiece fixing base, and then the electroplating liquid storage box 1 or the electroplating liquid brush head 2 is connected to an electrode, and another electrode is connected to the workpiece. The arranged workpieces to be electroplated are arranged and moved along the electroplating chute 21 so that the parts to be electroplated of the workpieces come into contact with the liquid-permeable cloth 3 permeated with the electroplating liquid, thereby achieving the technical effect of uniform electroplating without completely immersing the parts to be electroplated of the workpieces in the electroplating liquid.

[0032] It should be noted that the plating liquid brush head 2 is generally rectangular and has a width greater than that of the strip metal sheet. The top surface of the plating liquid brush head 2 is pre-coated with plating liquid. However, when electroplating a metal workpiece, the movement of the plating liquid on the workpiece in the plating liquid brush head 2 will interfere with the liquid level of the plating liquid, causing the liquid level of the plating liquid to fluctuate. The irregular fluctuation of the plating liquid level will cause uneven plating on the workpiece to be electroplated (especially some small metal workpieces), resulting in a high defective rate of the workpiece electroplating.

[0033] The present invention utilizes the liquid-permeable cloth 3 to siphon the plating liquid from the plating liquid holding tank 11 into the plating chute 21. During the electroplating operation, the workpiece is moved along the plating chute 21 so that the portion to be plated contacts the liquid-permeable cloth 3, which is permeated with the plating liquid. This achieves a uniform plating effect without completely immersing the portion to be plated in the plating liquid, effectively improving the efficiency of plating small workpieces.

[0034] Further, such as Figure 2 、 Figure 3As shown, the two sides of the plating liquid brush head 2 are close to the middle to form two inclined surfaces 22, and a corner 23 is formed between the two inclined surfaces 22. The plating chute 21 is set on the corner 23, and the liquid permeable cloth 3 is covered on the corner 23 and the two inclined surfaces 22.

[0035] Further, such as Figure 2 、 Figure 3 As shown, the two inclined surfaces 22 have the same width and the same inclination angle. This ensures that both sides of the permeable cloth 3 have the same siphoning efficiency for the electroplating solution, allowing the permeable cloth 3 to evenly penetrate the electroplating solution in the electroplating chute 21. This further ensures a more uniform electroplating effect on the workpiece.

[0036] Further, such as Figure 3 、 Figure 4 As shown, the bottom of the electroplating chute 21 is an arc-shaped concave structure. This arc-shaped concave bottom structure allows the liquid-permeable cloth 3 to be evenly contacted with the electroplating chute 21. This allows the electroplating liquid to be more evenly applied to the surface of the workpiece, uniformly plating the workpiece.

[0037] Furthermore, the liquid-permeable cloth 3 is cotton cloth. Cotton cloth has a good siphoning effect on liquid, and can efficiently siphon the electroplating liquid to the portion of the liquid-permeable cloth 3 located on the electroplating chute 21. This can effectively improve the electroplating efficiency of the workpiece to be electroplated.

[0038] Further, such as Figure 1 、 Figure 2 As shown, a storage basket 12 is provided in the electroplating liquid containing tank 11, and the storage basket 12 is used to place metal electroplating balls.

[0039] Furthermore, the storage basket 12 can be detachably connected to the electroplating solution containing tank 11 .

[0040] Further, such as Figure 2 、 Figure 3 As shown, a mounting base 24 is provided at the bottom of the electroplating liquid brush head 2 , and the electroplating liquid brush head 2 is fixed in the electroplating liquid containing tank 11 through the mounting base 24 .

[0041] Furthermore, the plating liquid container 1 and the plating liquid brush head 2 are both made of metal materials. The metal material structure is conductive and can not only meet the electrical connection of the entire plating head but also meet the long-term stable operation of the electroplating device.

[0042] Further, such as Figure 2 、 Figure 3 As shown, the sidewalls of the plating liquid brush head 2 are provided with several fixing members 25, which are used to secure the liquid-permeable cloth 3 to the plating liquid brush head 2. It is understood that when the workpiece to be plated rubs against the liquid-permeable cloth 3, the liquid-permeable cloth 3 and the plating liquid brush head 2 may become misaligned, affecting the liquid-permeable cloth 3's ability to accurately and evenly apply the plating liquid.

[0043] Therefore, in this embodiment, a plurality of fixing members 25 are provided on the side walls of the electroplating liquid brush head 2, and the liquid-permeable cloth 3 is fixed to the electroplating liquid brush head 2 by the fixing members 25. This prevents the liquid-permeable cloth 3 from shifting when the workpiece to be electroplated rubs against the liquid-permeable cloth 3, causing the liquid-permeable cloth 3 to be misaligned with the electroplating liquid brush head 2.

[0044] In summary, the present application provides a liquid-permeable electroplating brush head. The present invention uses a liquid-permeable cloth 3 to siphon the electroplating liquid in the electroplating liquid holding tank 11 into the electroplating chute 21. During the electroplating operation, the workpiece is moved along the electroplating chute 21 so that the part to be electroplated of the workpiece contacts the liquid-permeable cloth 3 permeated with the electroplating liquid, thereby achieving the technical effect of uniform electroplating without completely immersing the part to be electroplated of the workpiece in the electroplating liquid, thereby effectively improving the efficiency of electroplating small workpieces.

[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.
