Description

Technical Field

[0001] This utility model belongs to the field of electroplating equipment technology, specifically, it relates to an anode isolation box structure. Background Technology

[0002] An anode separator is a key auxiliary device in the electroplating process, mainly used to isolate the anode from the cathode (the workpiece to be plated), optimize the ion transport path, and manage bubbles generated during the electroplating process. Its core function is to improve the uniformity of the coating and reduce defects, and it is widely used, especially in horizontal continuous electroplating production lines.

[0003] In existing horizontal electroplating lines, the workpiece to be plated moves horizontally in the electroplating tank. Cathodes are set at intervals on the left and right sides of the workpiece. Under the action of current, the cathodes can electroplat copper ions in the electroplating solution onto the surface of the workpiece, thereby completing the coating.

[0004] like Figure 1 As shown, the current anode isolation box has multiple through holes arranged side by side at the bottom. This allows the chemical solution to circulate through the through holes, preventing ion concentration imbalance and bubble accumulation in the anode area and ensuring electroplating uniformity. However, the through hole design leads to excessive chemical exchange, which constantly consumes brightener during operation and requires frequent replenishment to maintain concentration, resulting in high costs and certain limitations. Utility Model Content

[0005] The purpose of this invention is to provide an anode isolation box structure that solves the technical problem in the prior art where the exchange of medicine and water is too frequent, resulting in continuous loss of light-emitting agent during operation, requiring frequent replenishment to maintain the concentration, and resulting in high costs.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An anode isolation box structure includes an isolation box base plate; the isolation box base plate has a first through hole and a second through hole symmetrically opened in the middle; the isolation box base plate has double threaded holes on both sides; the isolation box has a sealing mechanism fixedly installed at the positions corresponding to the upper and lower surfaces of the isolation box base plate; the sealing mechanism includes sealing caps located on the upper and lower surfaces of the isolation box base plate respectively.

[0008] Furthermore, the sealing mechanism includes a long plate; an integrally formed fixing part is fixedly connected to one end of the long plate near the double threaded hole; the fixing part has a corresponding fixing hole at the position of the double threaded hole; an installation part is fixedly connected to one end of the long plate near the first through hole or the second through hole; and the sealing cap is installed on the installation part.

[0009] Furthermore, the sealing cap has a hemispherical structure, and its surface is covered with EPDM.

[0010] Furthermore, the mounting part has a circular structure; a nail hole is provided in the middle of the mounting part; a screw is embedded in the flat part of the sealing cap, and the sealing cap is connected to the mounting part by the screw.

[0011] Furthermore, the sealing cap located on the upper part of the isolation box bottom plate has its arc surface facing downwards, while the sealing cap located on the lower part of the isolation box has its arc surface facing upwards.

[0012] Furthermore, the bottom plate of the isolation box has a double-layered rectangular structure, with the upper layer protruding into the interior of the isolation box and the lower layer fitting against the bottom surface of the isolation box at its periphery.

[0013] Furthermore, it also includes filter cloth fixed to the side of the isolation box; the side of the isolation box away from the filter cloth is fixed with hooks by threaded nails.

[0014] Furthermore, the fixing part is a rectangular plate structure with rounded corners; the fixing hole is a straight groove structure.

[0015] Furthermore, when the liquid flows upward, the larger diameter sealing cap located at the second through hole is restricted by the smaller diameter second through hole, preventing the second through hole from opening; when the liquid flows downward, the larger diameter sealing cap located at the first through hole is restricted by the smaller diameter first through hole, preventing the first through hole from opening.

[0016] The beneficial effects of this utility model are as follows: When the chemical solution flows upward, the larger diameter sealing cap located at the second through hole is restricted by the smaller diameter second through hole, preventing the second through hole from opening. When the chemical solution flows downward, the larger diameter sealing cap located at the first through hole is restricted by the smaller diameter first through hole, preventing the first through hole from opening. Therefore, the anode isolation box provided by this utility model can effectively control the amount of chemical solution in the isolation box by using two bidirectionally set sealing mechanisms, reducing the consumption of brightener and increasing the life of the anode titanium mesh.

It also includes an anode filter cloth 9 fixed to the side of the isolation box. The filter cloth 9 is made of PP and is used to output power lines during electroplating.

[0030] Please refer to it again. Figure 6 , Figure 7 as well as Figure 8As shown, the sealing mechanism 5 includes a long plate 501; an integrally formed fixing part 502 is fixedly connected to one end of the long plate 501 near the double threaded hole 2. The fixing part 502 has a rectangular plate structure with rounded corners; a corresponding fixing hole 503 is provided on the fixing part 502 corresponding to the position of the double threaded hole 2. The fixing hole 503 has a straight groove structure, and the position of the long plate 501 can be appropriately adjusted by threaded pins; a mounting part 504 is fixedly connected to one end of the long plate 501 near the first through hole 3 or the second through hole 4. The mounting part 504 has an integrally formed fixing part 502. It is currently a circular structure; a nail hole 505 is opened in the middle of the mounting part 504; a hemispherical sealing cap 7 is fixedly installed on the mounting part 504; the surface of the sealing cap 7 is covered with EPDM (ethylene propylene rubber) to improve the sealing effect; a screw 6 is embedded in the flat part of the sealing cap 7, and the sealing cap 7 is connected to the mounting part 504 by the screw 6; the sealing cap 7 located on the upper part of the isolation box bottom plate 1 is set with the arc surface facing down, and the sealing cap 7 located at the lower part of the isolation box is set with the arc surface facing up, wherein the long plate 501, the fixing part 502 and the mounting part 504 together constitute a spring steel plate structure.

[0031] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0032] Before the electroplating tank is filled with chemicals, the sealing caps 7 located at the bottom and top of the isolation box remain in contact with the first through hole 3 or the second through hole 4, thus maintaining the closed isolation box state, as they are not subjected to external forces.

[0033] When the chemical solution is introduced into the electroplating tank, it is injected from the bottom of the tank. At this time, the chemical solution exerts a force on the sealing cap 7 through the first through hole 3. This force is transmitted to the long plate 501. Since the fixing part 502 at the other end of the long plate 501 is fixed, the long plate 501 undergoes elastic deformation, causing the first through hole 3 to open and the chemical solution to enter the isolation box. When the chemical solution in the electroplating tank reaches the working liquid level, the upper and lower sides of the bottom plate 1 of the isolation box reach water pressure balance. The sealing cap 7 at the first through hole 3 returns to its original position under the elastic action of the long plate 501, thereby locking the valve, reducing the flow of chemical solution, and reducing the use of brightener.

[0034] When the electroplating operation stops, the chemical solution inside the electroplating tank flows out from the bottom of the electroplating tank. At this time, the chemical solution exerts a force on the sealing cap 7 through the second through hole 4 by gravity. The movement state is the same as that of the long plate 501 at the first through hole 3. The second through hole 4 is opened, and the chemical solution inside the isolation box is drained out through the second through hole 4 to prevent the chemical solution residue from continuing to damage the filter cloth 9.

[0035] It is worth noting that when the solution flows upward, the larger diameter sealing cap 7 located at the second through hole 4 is restricted by the smaller diameter second through hole 4, preventing the second through hole 4 from opening. When the solution flows downward, the larger diameter sealing cap 7 located at the first through hole 3 is restricted by the smaller diameter first through hole 3, preventing the first through hole 3 from opening. Therefore, the anode isolation box provided by this utility model can effectively control the amount of solution in the isolation box by using two bidirectionally set sealing mechanisms 5, reducing the consumption of light-reducing agent and increasing the life of the anode titanium mesh.
