Description

Technical Field

[0001] This utility model mainly relates to the field of electrode material production equipment technology, specifically a wetting device for preparing PCB titanium mesh anodes. Background Technology

[0002] With the development of science and technology, printed circuit boards (PCBs) have been trending towards lighter, thinner, shorter, smaller, and higher-density interconnects in recent years. To accommodate more micro-devices on a limited surface area, PCB design is increasingly focused on high precision, high density, multilayering, and small apertures. Through continuous research and development, the preparation methods for PCB anodes have also been continuously improved and perfected. Common coating methods include brush coating, electrostatic spraying, roller coating, vapor deposition, thermal spraying, and dip coating. Among these, brush coating is one of the most commonly used methods in modern industrial production, offering advantages such as flexible and simple operation, low cost, and high specificity. However, titanium mesh, due to its complex shape, is not suitable for this method. Dip coating, on the other hand, allows the coating to fully penetrate the pores of the titanium mesh anode, making it suitable for small or complex-shaped titanium mesh anodes, and resulting in strong coating adhesion.

[0003] Currently, the dip-coating method involves immersing the titanium mesh anode in a coating solution. However, it's difficult to precisely control the coating thickness, as this depends primarily on factors such as the coating viscosity, immersion time, and removal speed. Variations in these factors can lead to inconsistent coating thickness, resulting in excess coating solution remaining on the titanium mesh anode. Existing dip-coating wetting devices cannot remove this excess coating solution from the titanium mesh anode. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing dipping solutions are too simplistic. It mainly provides a wetting device for preparing PCB titanium mesh anodes, thereby solving the technical problem mentioned in the background that existing dipping devices cannot remove excess coating liquid from titanium mesh anodes.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An immersion apparatus for preparing PCB titanium mesh anodes includes a main housing, inside which are an immersion tank and a liquid removal tank. The liquid removal tank is provided with a rotating device for removing excess coating liquid from the surface of the PCB titanium mesh anode. The rotating device includes a clamping mechanism for holding the PCB titanium mesh anode and a rotary motor for driving the clamping mechanism to rotate.

[0007] Furthermore, the rotating device includes a mesh base plate, the clamping mechanism includes two opposing movable plates, and the opposite sides of the two movable plates are connected to telescopic studs via bearings. A nut with a threaded fit is fixedly connected to the mesh base plate and mounted on the telescopic studs. The rotating motor is installed at the bottom of the mesh base plate.

[0008] Furthermore, the movable plate has a parallel outer slot plate and an inner slot plate on the side facing away from the telescopic stud. The inner slot plate is vertically fixed to the movable plate, and a fixing stud is vertically fixed on the inner slot plate. The outer slot plate has a through hole for the fixing stud to pass through, and the outer slot plate has a threaded fastening nut that is fitted onto the fixing stud on the side facing away from the inner slot plate.

[0009] Furthermore, a sponge block is installed on the side of the inner plate of the card slot facing the outer plate of the card slot.

[0010] Furthermore, a washer fitted on the fixing stud is provided between the fastening nut and the outer plate of the slot.

[0011] Furthermore, a rotating box column with an open upper end is fixedly connected above the mesh base plate.

[0012] Furthermore, a support plate is provided inside the liquid removal tank, and the support plate is fixedly connected to the inner surface of the liquid removal tank by support bars, and the rotary motor is mounted on the support plate.

[0013] Furthermore, the main housing is provided with a funnel structure at the bottom of the liquid drain tank, and a cylindrical conduit is connected to the bottom of the center of the funnel structure.

[0014] Furthermore, the soaking tank is located on one side of the main body, the liquid drain is located on the opposite side of the soaking tank as a detachable first body panel, and the liquid drain is located directly in front of the liquid drain as a detachable second body panel.

[0015] Furthermore, the main body is provided with support legs at the bottom; and / or, the main body is provided with a lid at the top.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention includes an immersion tank for coating wetting, a rotating device for removing excess coating liquid from the anode surface, and a liquid removal tank. The immersed PCB titanium mesh anode is clamped in the rotating device, and driven to rotate by a rotating motor. Using centrifugal force and a suitable rotation speed limit, the excess coating liquid on the PCB titanium mesh anode is shaken off, making the coating of the titanium mesh anode uniform and with strong adhesion.

[0018] The immersion tank of this invention is designed with a narrow width, so that the coating liquid has a high liquid level. During application, the titanium mesh anode is kept upright and suspended in the immersion tank by hooks. The titanium mesh is completely immersed in the coating. Through capillary action and gravity, the coating can cover all parts of the titanium mesh relatively evenly. Especially for titanium mesh with complex shapes, it can better ensure the uniformity of the coating.

[0019] This invention has a simple structure and is easy to operate. It can fully penetrate the pores of the titanium mesh anode while removing excess coating liquid from the surface of the titanium mesh anode. It can also collect the removed coating liquid through a funnel structure and a cylindrical conduit for reuse.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Example 1: Please refer to the appendix for details. Figure 1 -Appendix Figure 4 An impregnation apparatus for preparing titanium mesh anodes for PCBs, comprising:

[0030] The main body is made of acid-resistant material; its bottom is supported on the ground by support legs 3, and its interior is equipped with an immersion tank 2 and a descaling tank; the immersion tank 2 is narrow and is used for coating wetting; the descaling tank is equipped with a rotating device to remove excess coating liquid from the anode surface;

[0031] Support legs 3, there are four of them, arranged in a rectangular array with the central axis of the main body as the center;

[0032] The cover 1 is located on the top of the main body and can be opened and closed. When closed, it simultaneously seals the soaking tank 2 and the liquid removal tank. In addition to protecting the operators during operation, it can also retain the coating liquid in the device for recycling.

[0033] The rotating device includes a mesh base plate 11 for excess coating liquid to leak out and drain; a clamping mechanism for clamping the PCB titanium mesh anode is installed on the mesh base plate 11, the clamping mechanism includes two oppositely arranged movable plates 18, and telescopic studs 16 are connected to the opposite sides of the two movable plates 18 through bearings; a nut 17 threadedly adapted and fitted onto the telescopic studs 16 is fixedly connected to the mesh base plate 11.

[0034] A rotary motor 13 for driving the mesh base plate 11 to rotate is connected to the bottom of the mesh base plate 11. The rotary motor 13 is mounted on the support plate 10, which is fixedly connected to the inner surface of the liquid draining tank by the support strip 15, so that the mesh base plate 11 can be stably suspended in the middle of the liquid draining tank. The power cord 9 of the rotary motor 13 extends to the outside of the main housing.

[0035] The main tank body is equipped with a funnel structure at the bottom of the liquid removal tank to facilitate the collection of the removed coating liquid; and a cylindrical conduit 6 is connected to the bottom center of the funnel structure to drain excess coating liquid from the main tank body. The main tank body is equipped with a drain port at the bottom of the soaking tank 2 to drain the coating liquid therein, and the drain port is equipped with a valve or plug.

[0036] In application, the immersion tank 2 is filled with coating liquid. The cut titanium anode is suspended in the immersion tank 2 with hooks, so that it is completely immersed in the coating liquid, thereby evenly covering all parts of the titanium mesh. Then, the titanium anode with more coating liquid on its surface is taken out and clamped on the clamping mechanism. By rotating the telescopic stud 16, the telescopic stud 16 is translated relative to the nut 17, and the moving plate 18 moves accordingly, so that the distance between the two moving plates 18 is adjustable, thus adapting to titanium anodes of different sizes. Finally, the rotary motor 13 is started, which drives the mesh base plate 11 to rotate, thereby driving the titanium anode to rotate and shake off the excess coating liquid. The excess coating liquid falls through the mesh base plate 11 onto the funnel structure and collects at the location of the cylindrical guide tube 6, and can finally be discharged and collected from the cylindrical guide tube 6.

[0037] To ensure appropriate removal of coating liquid from the PCB board, the rotation speed and rotation time of the rotary motor 13 are matched to different applicable ranges according to actual conditions. In laboratory environments or general initial processing in industrial production, the rotation speed for removing coating liquid from the PCB board is typically 900-3000 rpm. If the speed is too low, the centrifugal force on the liquid is insufficient, making it difficult to effectively detach from the board surface; if the speed is too high, it may cause displacement or damage to the board during operation, and may also pose safety hazards. However, for some more fragile boards or boards with extremely high precision requirements, the speed may be reduced to 500-1000 rpm. For some boards that can withstand greater centrifugal force, are harder in texture, and have a larger area, and where the liquid has a higher viscosity, the speed can be appropriately increased to 3000-5000 rpm. In addition, depending on the properties of the liquid and the characteristics of the board, the time for removing the liquid is usually around 30 seconds to 3 minutes. If the liquid has low viscosity (such as isopropanol) and a small area, 30 seconds to 1 minute may be sufficient to remove most of the liquid from the board. However, for highly viscous liquids (such as certain coating solutions containing high concentrations of polymers or viscous chemical reagents), it may take 2-3 minutes or even longer. These time ranges will vary depending on many factors such as the material, size, and shape of the board, as well as the type and amount of liquid. In actual operation, appropriate adjustments and experiments need to be made according to specific circumstances to achieve the best liquid removal effect while ensuring the safety of the board.

[0038] Example 2: The difference between this example and Example 1 is that:

[0039] Please refer to the attached document carefully. Figure 3 The movable plate 18 has a parallel outer slot plate 19 and an inner slot plate 21 on the side facing away from the telescopic stud 16, with the outer slot plate 19 and inner slot plate 21 facing each other. The inner slot plate 21 is vertically fixed to the movable plate 18, and a fixing stud 20 is vertically fixed on the inner slot plate 21. The outer slot plate 19 has a through hole for the fixing stud 20 to pass through. The side of the outer slot plate 19 facing away from the inner slot plate 21 has a threaded fastening nut 22 that is fitted onto the fixing stud 20, and a washer 23 fitted onto the fixing stud 20 is provided between the fastening nut 22 and the outer slot plate 19. By rotating the fastening nut 22, the outer slot plate 19 can be pushed towards the side where the inner slot plate 21 is located. Thus, based on the two movable plates 18 clamping the left and right sides of the titanium anode, the outer slot plate 19 and inner slot plate 21 can clamp the front and rear ends of the titanium anode, thereby better clamping the titanium anode.

[0040] A sponge block 24 is installed on the side of the inner plate 21 facing the outer plate 19 of the slot to ensure that the sample is not damaged when fixing the titanium anode.

[0041] The rest is the same as in Example 1.

[0042] Example 3: The difference between this example and Example 2 is that:

[0043] Please refer to the attached document carefully. Figure 1 The main body is a rectangular structure, and the funnel structure at the bottom of the main body is mainly composed of four inclined plates.

[0044] Please refer to the attached document carefully. Figure 1 The immersion tank 2 is located on one side of the main body, and the liquid removal tank is located on the opposite side of the immersion tank 2. The first tank plate 4 is detachable, and the second tank plate 8 is detachable in front of the liquid removal tank. They can be removed when placing the anode, which makes it convenient for staff to quickly fix the titanium anode.

[0045] Please refer to the attached document carefully. Figure 1 and attached Figure 2 A rotating box column 5 with an open top is fixedly connected above the mesh base plate 11 to reduce the range of coating splash; a telescopic stud 16 extends to the outside of the rotating box column 5. A fixing plate 12 is provided at the center of the mesh base plate 11, and a rotating support column 14 is connected to the bottom surface of the fixing plate 12. A rotating motor 13 is installed below the rotating support column 14.

[0046] The rest is the same as in Example 2.
