Description

Technical Field

[0001] This utility model relates to the field of wheel electrophoresis technology, and in particular to a wheel electrophoresis degassing bag device. Background Technology

[0002] In the electrophoretic coating process for automotive steel wheels, two steel wheels are typically hung back-to-back on a specialized hanger mounted on a catenary track, which moves via the catenary. When the wheel is fully immersed in the electrophoretic solution in the tank, a cavity forms between the inner wall of the highest point of the wheel rim and the solution. Because this cavity contains air, the electrophoretic film formation within it is poor, resulting in what is known as an air pocket, a quality defect. This defect requires manual touch-up painting after drying, which not only increases the cost of the touch-up paint can but also incurs additional costs for manual inspection and touch-up. Utility Model Content

[0003] In view of this, the present invention aims to provide a wheel electrophoresis degassing bag device, which uses a catenary track to drive the hanger to travel along the toothed structure, thereby eliminating the cavities formed by air bubbles in the electrophoresis liquid on the wheel surface.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A wheel electrophoresis degassing bag device includes an electrophoresis tank, a catenary track, a wheel hanger, and a degassing device. The catenary track is located above the electrophoresis tank. One end of the wheel hanger is suspended on the catenary track, and the other end of the wheel hanger suspends the wheel, allowing the wheel to be immersed in the electrophoresis tank. The degassing device is installed on the electrophoresis tank. The degassing device has a toothed structure. The catenary track drives the wheel to travel along the toothed structure through the wheel hanger, thereby eliminating the cavity formed by air bubbles between the outer surface of the wheel and the electrophoresis liquid.

[0006] Furthermore, the debubbling device includes a connecting frame and a toothed plate with a toothed structure. The toothed plate is connected to the electrophoresis tank via the connecting frame, and the toothed structure is located inside the electrophoresis tank.

[0007] Furthermore, the toothed plate also has a guide ramp.

[0008] Furthermore, the toothed structure includes at least three teeth.

[0009] Furthermore, the outer contour of each tooth is a right-angled trapezoid.

[0010] Furthermore, the toothed plate is made of insulating material.

[0011] Furthermore, the toothed plate is made of nylon.

[0012] Furthermore, the connecting frame has a U-shaped structure.

[0013] Furthermore, the connecting frame is formed by welding rectangular or square tubes.

[0014] Compared with the prior art, the present invention can achieve the following beneficial effects:

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 3 As shown in the figure, an embodiment of this utility model provides a wheel electrophoresis degassing bag device, including an electrophoresis tank 1, a catenary track 2, a wheel hanger 3, and a degassing device 4. The catenary track 2 is located above the electrophoresis tank 1. One end of the wheel hanger 3 is suspended on the catenary track 2, and the other end of the wheel hanger 3 suspends the wheel, allowing the wheel to be immersed in the electrophoresis solution in the electrophoresis tank 1. The degassing device 4 is disposed on the electrophoresis tank 1 and is located above the electrophoresis solution level in the electrophoresis tank 1. The degassing device 4 has a toothed structure. The catenary track 2 drives the wheel hanger 3 to travel along the toothed structure, thereby eliminating the cavity formed by air bubbles between the wheel surface and the electrophoresis solution.

[0030] The de-bubble device 4 includes a connecting frame 41 and a toothed plate 42 with a toothed structure. The bottom surface of the toothed plate 42 is connected to the connecting frame 41 by bolts. The connecting frame 41 is connected to the electrophoresis tank 1. The toothed structure of the toothed plate 42 is located inside the electrophoresis tank 1.

[0031] Furthermore, the connecting frame 41 has a U-shaped structure and is formed by welding rectangular or square tubes. In this embodiment, the connecting frame 41 is formed by welding square tubes with a cross-sectional dimension of 40mm×40mm and a wall thickness of 3mm.

[0032] The toothed plate 42 also has a guide ramp 421. The catenary track 2 drives the wheel hanger 3 along the guide ramp 421 into the toothed structure, and the wheel hanger 3 travels along the toothed structure. When the wheel hanger 3 reaches the highest point of the toothed structure, it will suddenly fall due to gravity, causing the wheel to vibrate. The air in the cavity between the wheel surface and the electrophoretic liquid will then escape after the vibration. The vibration of the wheel hanger 3 in the toothed structure completely expels the air from the cavity, thus ensuring the quality of the electrophoretic film formation on the wheel and eliminating the air pocket phenomenon.

[0033] Furthermore, the toothed structure includes at least three spaced teeth 422. In this embodiment, to more effectively eliminate cavities formed by air bubbles, the toothed plate is provided with four teeth 422. The outer contour of each tooth 422 is a right-angled trapezoid.

[0034] Furthermore, the toothed plate 42 is made of insulating nylon. Therefore, during use, the toothed plate 42 will not affect the normal operation of the electrophoresis tank 1 due to conductivity. At the same time, since the toothed plate 42 is made of nylon, the wheel hanger 3 will not be damaged when it travels along the toothed structure of the toothed plate 42.

[0035] In this embodiment, the toothed plate 42 has a thickness of 40 mm, and the angle (α) between the guide slope 421 and the bottom surface of the toothed plate 42 is 40°. The tooth spacing between two adjacent teeth 422 is 141.5 mm, the groove width between two adjacent teeth 422 is 50 mm, and the height of the teeth 422 is 60 mm. This ensures both the strength and stability of the toothed plate 42, while also ensuring that air bubbles can be eliminated.

[0036] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
