Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to an anode box assembly for a horizontal electroplating line. Background Technique

[0002] In the existing horizontal electroplating line, the material to be electroplated runs horizontally in the electroplating tank, and insoluble anodes are arranged at intervals on the upper and lower sides of the plate. To ensure that the distance between the anode and the plate surface of the material to be electroplated is the same, insoluble anodes are mostly used.

[0003] During the electroplating process, oxygen is precipitated on the surface of the insoluble anode located below the material to be electroplated, forming oxygen bubbles in the electroplating solution. The oxygen bubbles float up and adhere to the surface of the material to be electroplated. If the bubbles are not discharged in time, pinholes, pits, etc. are likely to be formed after electroplating, further affecting the product qualification rate, so there are certain limitations in use.

[0004] Therefore, it is necessary to provide an anode box assembly for a horizontal electroplating line to solve the above technical problems. Content of the Utility Model

The secondary guiding and discharging of gas can be realized through the support components.

[0007] As a further scheme of the utility model, the diaphragm is made of a hydrophilic material, and the diaphragm is arranged in a V-shaped layout as a whole.

[0008] As a further scheme of the utility model, the jet module is located at the middle position below the lower anode or the jet module is located at the middle position between the diaphragm and the lower anode.

[0009] As a further scheme of the utility model, the diaphragm is arranged obliquely in a straight line, and the jet module is arranged below the lower side of the diaphragm.

[0021] Embodiment 1:

[0022] Please refer to Figures 1 to 3 , the embodiment of the present utility model provides an anode box assembly for a horizontal electroplating line, which is mainly used to ensure the uniformity and stability of the coating. Specifically, it includes a housing 1, a frame 2 is fixedly installed inside the housing 1, a lower anode 3 and a jet module 6 are fixedly installed inside the frame 2, a diaphragm 4 is fixedly installed on the top of the frame 2, and support assemblies 5 fixedly connected to the frame 2 are fixedly installed at both ends of the diaphragm 4; through the support assemblies 5, the effective guiding and discharging of gases can be realized, and the discharging distance is farther, avoiding the influence of bubbles on the quality of the material to be plated.

[0023] In the above structure, the jet module 6 is located at the middle position below the lower anode 3. At this time, the water flow impact formed by the jet module can proceed simultaneously in both directions, which can accelerate the separation of the bubbles generated on the lower anode 3 from the lower anode 3. After separation, the plating solution and the gas are separated through the diaphragm 4, thereby increasing the effective area of the lower anode 3 participating in the discharge and improving the uniformity and stability of the coating. In practical applications, the jet module 6 can also be arranged at the middle position between the diaphragm 4 and the lower anode 3, and the water flow impacts the surface of the lower anode 3 in one or multiple directions.

[0024] Furthermore, the diaphragm 4 is actually a hydrophilic material, which utilizes the property that a hydrophilic film is formed on the surface of the hydrophilic material by the plating solution to hinder the passage of gases such as oxygen, while liquids such as water can pass through the hydrophilic material. The diaphragm 4 can be modified PTFE / PVDF / PP, or hydrophilic organic polymer materials such as PA / PAF, or a porous corrosion-resistant ceramic structure, etc. Among them, the form of the diaphragm 4 can be textile cloth, gauze, non-woven fabric, and porous film, etc. The core of the diaphragm 4 is good hydrophilicity and corrosion resistance to the plating solution.

[0025] Among them, the diaphragm 4 is arranged in a V shape as a whole, corresponding to the water flow impacts on both sides of the jet module 6. The diaphragm 4 is located between the material to be plated and the lower anode 3. Since the surface of the diaphragm 4 facing the material to be plated forms a V-shaped surface, the oxygen generated by the reaction of the lower anode 3 in the electroplating solution, after being impacted by the jet module 6 and rising to the surface of the diaphragm 4, is blocked by the surface of the diaphragm 4 to discharge the bubbles to both sides (this is the primary guiding discharge), and is further guided and discharged through the support assembly 5, so that the material to be plated in the concave area will not be affected by the bubbles.

[0026] Specifically, referring to Figure 1 and Figure 3 , where the direction of the arrow is the gas flow direction 7. At this time, the gas is first discharged to both sides through the diaphragm 4, and then further guided to both sides through the support assembly 5. Finally, it can move to the outside of the frame 2 on both sides and then rise. At this time, the gas is farther away from the concave area of the V-shaped partition.

[0027] In this embodiment, the structures of the lower anode 3, the frame 2, and the diaphragm 4, as well as the working principles of the lower anode 3 and the diaphragm 4, are all existing mature technologies and will not be elaborated here in detail.

[0028] In summary, through the cooperation of structures such as the lower anode 3, the diaphragm 4, the support assembly 5, and the jet module 6, a hydrophilic film is formed to hinder the passage of gases such as oxygen, and the generated gas can also be guided to be discharged at a farther distance, avoiding the gas adhering to the surface of the material to be plated, which can effectively improve the uniformity and stability of the coating, and the overall practicality is higher.

[0029] Embodiment 2:

[0030] Please refer toFigures 1 to 5 , on the basis of the first embodiment, the support assembly 5 includes a long strip plate 501 fixedly connected to the diaphragm 4. The surface of the long strip plate 501 away from the diaphragm 4 is flush with the side wall of the frame 2, and a support column 502 is fixedly installed between the bottom of the long strip plate 501 and the surface of the frame 2. Thus, after the gas is guided by the diaphragm 4, it can be further guided by the long strip plate 501 and then discharged from between the frame 2 and the long strip plate 501.

[0031] Furthermore, referring to Figure 4 , if the material of the diaphragm 4 is relatively soft, a plurality of skeletons 401 can be fixedly installed on the bottom surface of the diaphragm 4 to ensure the stable shape of the diaphragm 4; among them, the plurality of skeletons 401 can also be arranged in a rectangular array.

[0032] Among them, referring to Figure 5 , the diaphragm 4 can also be arranged obliquely in a straight line. At this time, the jet module 6 needs to be arranged on the lower side of the diaphragm 4 so that the jet module 6 can impact from the lower side of the diaphragm 4 to the higher side; the above arrangement is more suitable for plate-shaped insoluble anodes.

[0033] In summary, through the cooperation of structures such as the diaphragm 4, the long strip plate 501, the support column 502, and the frame 2, the generated gas can be guided and discharged over a relatively long distance, effectively preventing the gas from contacting the material to be plated, and thus ensuring the uniformity and stability of the coating. At the same time, the arrangement methods and positions of the diaphragm 4 and the jet module 6 are diversified, so that the applicable range is greatly improved, meeting more requirements in actual use.
