Description

Technical Field

[0001] This utility model relates to the field of passivation machine technology, and in particular to a passivation machine for surface pretreatment of workpieces for new energy vehicles. Background Technology

[0002] In the current booming development of the new energy vehicle industry, the manufacturing quality and performance of automotive parts are of paramount importance. Among them, the pretreatment of the workpiece surface is a key step to ensure the quality of subsequent processing and service life. Passivation treatment, as an important surface pretreatment process, can significantly improve the corrosion resistance of the workpiece, reduce the risk of failure caused by corrosion in complex use environments, and thus ensure the overall safety and reliability of new energy vehicles.

[0003] Traditional passivation methods for automotive parts have many drawbacks. During the passivation process, the workpiece is usually placed directly into a container filled with passivation solution and left to soak. This method results in uneven contact between the workpiece and the passivation solution, leading to inconsistent passivation effects. Some areas may not be passivated sufficiently, affecting the corrosion resistance of the workpiece. After passivation, it is also inconvenient to remove the automotive workpiece.

[0004] In summary, existing passivation methods for automotive parts can no longer meet the demands of the new energy vehicle industry for high-quality and high-efficiency processing of parts. Therefore, developing a new type of passivation machine for surface pretreatment of new energy vehicle parts to improve the quality and efficiency of passivation is of great practical significance.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] A passivation machine for surface pretreatment of new energy vehicle workpieces, such as Figures 1 to 4 As shown, it includes a passivation cylinder 1, a lifting assembly is installed on the side of the passivation cylinder 1, a connecting plate 6 is installed at the output end of the lifting assembly, a connecting column 20 is rotatably connected to the bottom of the connecting plate 6, a drive motor 16 is fixed to the top outer wall of the connecting plate 6 by bolts, the output end of the drive motor 16 is connected to the top of the connecting column 20 by a coupling, and a mesh box 17 is fixed to the bottom of the connecting column 20.

[0028] When passivation of automotive parts is required, the passivation tank 1 can be used to store the passivation solution. The passivation solution contains inorganic salts such as chromates, phosphates, and nitrates as the main film-forming substances to promote the formation of a dense passivation film on the surface of the workpiece. At the same time, organic acids such as citric acid and tartaric acid are added to adjust the acidity and stability of the solution. Some also contain corrosion inhibitors to prevent excessive corrosion of the automotive parts, and surfactants to improve the wettability of the solution, ensuring that the passivation solution can evenly cover the surface of the automotive parts, improving the passivation effect and the corrosion resistance of the automotive parts. The height of the mesh box 17 can be adjusted using the lifting component. When the height of the mesh box 17 is higher than the liquid level of the passivation solution inside the passivation tank 1, the automotive parts to be passivated are placed in the mesh box 17. Then, the lifting component is used to drive the mesh box 17 to move down, so that the automotive parts in the mesh box 17 are immersed in the passivation solution for passivation treatment.

[0029] During the passivation process, the drive motor 16 drives the connecting column 20 and the mesh box 17 to rotate at a low speed. The mesh box 17 drives the automotive workpiece inside to rotate, so that the automotive workpiece can make more uniform contact with the passivation liquid.

[0030] The lifting assembly includes a mounting plate 4 and an electric telescopic rod 5. The mounting plate 4 is fixed to the side wall of the passivation cylinder 1 by bolts, and the electric telescopic rod 5 is fixed to the top outer wall of the mounting plate 4 by bolts. The output end of the electric telescopic rod 5 and the connecting plate 6 are fixed by pins.

[0031] The electric telescopic rod 5 can be used to control the mesh box 17 to move up or down, thereby immersing the automotive workpiece inside the mesh box 17 into the passivation solution.

[0032] A partition 19 is welded between the mesh box 17 and the connecting column 20, and a mesh placement frame 18 is placed in the gap between the partition 19 and the mesh box 17.

[0033] To facilitate passivation of different types of automotive workpieces and avoid confusion, the mesh placement frame 18 allows for the independent placement of different types of automotive workpieces. After passivation, it also facilitates the quick removal of the automotive workpieces from the mesh box 17. The partition 19 divides the interior of the mesh box 17 into multiple independent chambers, thereby facilitating the placement of the mesh placement frame 18.

[0034] The passivation cylinder 1 has a discharge pipe 14 welded to its bottom outer wall, and a valve 15 is fixed to the bottom outer wall of the discharge pipe 14 by bolts.

[0035] After the automotive workpiece has been passivated, valve 15 is opened so that the passivation liquid inside the passivation cylinder 1 can be discharged through the discharge pipe 14 and valve 15.

[0036] The connecting plate 6 has a through hole on its surface that is slidably connected to a T-shaped rod 8. The bottom of the T-shaped rod 8 is fixed with a cover plate 10 by screws. A sealing gasket 12 is glued to the bottom of the cover plate 10. A spring 7 is sleeved on the outer wall of the T-shaped rod 8. The two ends of the spring 7 are respectively fixed to the inner top wall of the T-shaped rod 8 and the outer top wall of the connecting plate 6.

[0037] To prevent the passivation liquid from splashing out when the drive motor 16 drives the mesh box 17 and the connecting column 20 to rotate during the passivation process, the top of the passivation cylinder 1 is covered by the cover plate 10. At the same time, the spring 7 is provided so that when the sealing gasket 12 at the bottom of the cover plate 10 is in contact with the top of the passivation cylinder 1, the lifting assembly can continue to drive the mesh box 17 to move down along the inside of the passivation cylinder 1, thereby ensuring that the automotive workpiece inside the mesh box 17 can be completely immersed in the passivation liquid. The sealing gasket 12 improves the sealing between the cover plate 10 and the passivation cylinder 1.

[0038] The top opening of the cover plate 10 has a through hole in which a multi-vent pipe 13 is embedded. A drying component is installed at the end of the multi-vent pipe 13 away from the cover plate 10. The drying component includes a vertical plate 9 and a fan 11. The vertical plate 9 is fixed to the top outer wall of the cover plate 10 by bolts. The fan 11 is fixed to the outer wall of one side of the vertical plate 9 by bolts, and the output end of the fan 11 is fixedly connected to the multi-vent pipe 13.

[0039] After the automotive workpiece has been passivated, the lifting assembly drives the mesh box 17 to move out of the passivation liquid, and the fan 11 blows air into the multi-vent pipe 13 to dry the passivated automotive workpiece.

[0040] A controller 2 is installed on the side wall of the passivation cylinder 1;

[0041] The controller 2 controls the electric telescopic rod 5 to immerse or remove the mesh box 17 into the passivation liquid, and simultaneously drives the motor 16 to start and stop to rotate the mesh box 17. The fan 11 is synchronously controlled to dry the workpiece through the multi-pass air pipe 13 after it is removed, ensuring that the lifting, rotation and drying are automatically executed according to the process sequence.

[0042] The passivation cylinder 1 is welded with a support leg 3 on its side;

[0043] The passivation cylinder 1 can be supported by the support leg 3.

[0044] Working principle: During operation, the controller 2 first instructs the electric telescopic rod 5 to extend, which drives the mesh box 17 to move vertically upward to above the passivation liquid level in the passivation cylinder 1 via the connecting plate 6. The operator then sorts and places the automotive workpieces to be processed into the mesh placement frame 18 inside the mesh box 17. Subsequently, the electric telescopic rod 5 retracts in the opposite direction, immersing the mesh box 17 with the workpieces into the passivation liquid. At the same time, the drive motor 16 starts and drives the mesh box 17 to rotate via the connecting column 20, ensuring that the workpieces are in full and even contact with the passivation liquid. During this process, the spring 7 continuously applies pressure to ensure that the cover plate 10 is tightly fitted to the top of the passivation cylinder 1 through the sealing gasket 12 to prevent liquid splashing. After the passivation process is completed, the electric telescopic rod 5 extends again to lift the mesh box 17 out of the liquid surface. The controller 2 simultaneously starts the fan 11, and the airflow blows and dries the workpieces from all directions through the multi-port air pipe 13.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
