Description

Technical Field

[0001] This utility model belongs to the field of automotive body electrophoresis technology, and in particular relates to an auxiliary device for increasing the film thickness of the interior film of blind windows. Background Technology

[0002] In the automobile manufacturing process, ensuring the quality of the interior surface coating is crucial for the production of blind window vehicles. Currently, the mainstream automotive body-in-white painting process adopts cathodic electrophoresis. In this process, the car body acts as the cathode during electrophoresis, while the anode film tubes installed at the bottom, side, and top of the tank act as the anode. When electricity is applied, an electric field is formed between the anode film tubes and the car body, and the electrophoretic paint is adhered to the car body through electrochemical principles.

[0003] However, for vehicles with blind windows, the internal electric field is shielded, resulting in poor electrophoresis in the interior cavity. The thickness of the electrophoretic paint film on the interior surface is difficult to meet the standard requirements, which seriously affects the corrosion resistance and overall quality of the body-in-white. In particular, during the electrophoresis process of some large blind window vehicles, the failure rate of the electrophoretic paint film thickness in the roof and some interior areas is relatively high, which cannot meet the corrosion resistance requirements during long-term use of the vehicle. This not only increases the cost of subsequent maintenance and repair, but may also have an adverse effect on the safety and durability of the vehicle.

[0004] The application number is CN201821410864.0 A utility model patent discloses an auxiliary anode device for improving the electrophoretic effect on the inner surface of a closed blind window vehicle. The device includes several auxiliary anode plates, a connecting hinge, an anode plate hook, a hook insulating plate, and a pull screen. One end of each auxiliary anode plate is connected to the connecting hinge, allowing the auxiliary anode plates to open and form the auxiliary anode device. One end of the hook insulating plate is fixed to the auxiliary anode plate, and one end of the anode plate hook is connected to the other end of the hook insulating plate. The pull screen is connected to the anode plate hook, preventing the auxiliary anode device from contacting the anode plate hook and pull screen. The device is then hung within the inner cavity electric field of the blind window vehicle via the anode plate hook and pull screen. This utility model patent effectively strengthens the inner cavity electric field of the blind window vehicle through the cross-shaped auxiliary anode device, reducing the occurrence of shielding of the inner cavity electric field in closed blind window vehicles, and has good self-insulation. It enables the electrophoretic paint to be evenly and effectively deposited on the inner cavity surface of the vehicle body, improving the corrosion resistance of the inner cavity surface of the white body and improving the quality of the finished product. However, this utility model patent still suffers from uneven film thickness in the inner cavity of blind window vehicles, and the auxiliary anode plates are prone to deformation during use, affecting performance. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide an auxiliary device for increasing the film thickness of the inner cavity film of a blind window vehicle. This device can effectively increase the electric field inside the vehicle cavity, so that the electrophoretic paint can be more evenly and effectively adhered to the inner surface of the vehicle, thereby increasing the film thickness of the electrophoretic paint on the inner surface of the car body and improving the corrosion resistance and overall quality of the inner cavity surface of the white body.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An auxiliary device for increasing the thickness of the inner film of a blind window vehicle includes two suspension hooks arranged at a certain distance. The two suspension hooks are connected to an auxiliary anode main assembly through a connecting component with an insulating function. The auxiliary anode main assembly includes an anode cylinder, and an anode support frame is arranged inside the anode cylinder.

[0007] The following are further optimizations of the above technical solution by this utility model: The anode support frame includes two anode plates, which are fixedly connected and arranged vertically. Both ends of the anode plates are fixedly connected to the inner wall of the anode cylinder.

[0008] Further optimization: Multiple first through holes are opened on the anode plate, and multiple second through holes are opened on the anode cylinder.

[0009] Further optimization: Both ends of the anode cylinder are fixed with protective edges.

[0010] Further optimization: The connecting component includes an insulating plate, one end of which is attached to a suspension hook, and the other end of the insulating plate is attached to a connecting hook. The end of the connecting hook away from the suspension hook is attached to the anode cylinder.

[0011] Further optimization: Both the anode plate and the anode cylinder are made of 1.5mm thick SUS316L stainless steel plate.

[0012] Further optimization: The edge guard is made of 3mm thick SUS316L stainless steel sheet.

[0013] Further optimization: The insulation board is made of fiberglass sheet with a thickness of 10mm.

[0014] This utility model structure, through rational design, has the following advantages: Significantly improved film thickness: The perforated anode cylinder structure design can concentrate the electrophoretic current to the inner cavity area of ​​the blind window vehicle. Combined with the evenly distributed through holes, the blind window area receives sufficient and uniform electrophoretic current, significantly improving the film thickness in this area. Tests have shown that the film thickness in the blind window area can be doubled, meeting the requirements for corrosion protection and coating quality. Easy installation and maintenance: It adopts a suspended installation, which does not require large-scale modification of the electrophoresis production line. The installation process is simple and quick, the device has a simple structure, no complicated parts, and convenient daily maintenance. Good economic benefits: It effectively solves the problem of insufficient film thickness in blind windows, reduces the risk of rework or anti-corrosion failure due to substandard film thickness, and lowers production and after-sales costs.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0018] like Figure 1 As shown, an auxiliary device for increasing the thickness of the inner film of a blind window vehicle includes two suspension hooks 1 arranged at a certain distance. The two suspension hooks 1 are connected to an auxiliary anode main assembly through a connecting component with an insulating function.

[0019] With this design, the auxiliary anode device can concentrate the electrophoretic current and guide it to the inner cavity area of ​​the blind window vehicle body, so that the inner cavity area of ​​the blind window vehicle body can obtain sufficient and uniform electrophoretic current, significantly improving the film thickness in this area. The suspension hook 1 can suspend the entire auxiliary anode device on the suspension system of the electrophoretic line. The connecting component plays an insulating role, so that the positively charged auxiliary anode main component is insulated and isolated from the negatively charged blind window vehicle body.

[0020] The suspension hook 1 is made of corrosion-resistant material, preferably stainless steel round bar with a diameter of 8mm, to ensure its structural stability and conductivity for long-term use in the electrophoresis environment, and is compatible with the interface of the existing electrophoresis line suspension system for easy installation.

[0021] The auxiliary anode main assembly includes an anode cylinder 5, and an anode support frame is installed inside the anode cylinder 5.

[0022] The anode cylinder 5 is made of 1.5mm thick SUS316L stainless steel plate with good electrical conductivity.

[0023] Multiple second through holes 501 are provided on the anode cylinder 5.

[0024] The diameter of the second through hole 501 is preferably 20 mm, and the hole spacing is preferably 50 mm, which are evenly distributed on the cylinder body of the anode cylinder 5.

[0025] With this design, the anode cylinder 5 of the cylindrical structure can extend into the inner cavity region of the blind-window vehicle body, and the second through hole 501 can increase the contact area between the anode and the electrophoretic paint, meanwhile allowing the electrophoretic current to diverge uniformly in all directions, which targetedly increases the film thickness in the blind-window region, avoids local over-electrophoresis and uneven film thickness caused by current concentration, and reduces the weight of the anode cylinder 5 at the same time.

[0026] Edge guards 6 are fixedly connected to both ends of the anode cylinder 5, so as to enhance the structural strength of the anode cylinder 5 and prevent it from deforming in the electrophoresis tank due to liquid flow or its own weight.

[0027] The edge guard 6 is made of a SUS316L stainless steel plate with a thickness of 3 mm.

[0028] The anode support frame includes two anode plates 4, the two anode plates 4 are fixedly connected and arranged perpendicularly, and both ends of each anode plate 4 are fixedly connected to the inner wall of the anode cylinder 5.

[0029] With this design, the anode support frame forms a cross-shaped structure, which not only increases the anode area of the auxiliary anode main body assembly, but also supports the anode cylinder 5, increasing the strength of the auxiliary anode main body assembly.

[0030] Besides this embodiment, the anode support frame can also be of other structures such as a Y-shaped structure or a米-shaped structure.

[0031] The anode plate 4 is made of a SUS316L stainless steel plate with good electrical conductivity and a thickness of 1.5 mm.

[0032] A plurality of first through holes 401 are opened on the anode plate 4.

[0033] The aperture of the first through holes 401 is preferably 20 mm, the hole spacing is preferably 50 mm, and the first through holes 401 are uniformly distributed on the anode plate 4.

[0034] With this design, the first through holes 401 can increase the contact area between the anode and the electrophoretic paint, which is beneficial to increasing the film thickness in the blind-window region, and at the same time reduces the weight of the anode support frame, thereby reducing the weight of the auxiliary anode main body assembly.

[0035] The connecting assembly includes an insulating plate 2, one end of the insulating plate 2 is hooked to the suspension hook 1, the other end of the insulating plate 2 is hooked with a connecting hook 3, and one end of the connecting hook 3 away from the suspension hook 1 is hooked to the anode cylinder 5.

[0036] The insulating plate 2 is made of insulating material, preferably a glass steel plate with dimensions of 150×50×10 mm (length × width × thickness), which insulates and isolates the positively charged anode cylinder 5 from the negatively charged suspension hook 1.

[0037] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
