Description

Technical Field

[0001] This application relates to the field of automotive coating electrophoresis technology, specifically to a paint receiving fixture and a coating system. Background Technology

[0002] During the electrophoresis process of a car body, electrophoretic paint accumulates inside the body. Due to structural limitations, some electrophoretic paint cannot be completely discharged. This causes the surface tension of the electrophoretic paint to be disrupted when heated in the electrophoresis drying oven. The accumulated electrophoretic paint expands and flows out, eventually reaching the fender surface, thus creating electrophoretic flow marks. Utility Model Content

[0003] This application provides a paint splicing fixture and a coating system that can reduce the risk of electrophoretic flow marks on fenders and simplify the installation of the paint splicing fixture.

[0004] This application provides a paint receiving fixture. The paint receiving fixture includes a fixing assembly for securing to a support member of a vehicle. The support member is configured to support the vehicle's hood and fenders when the hood is closed. The paint receiving fixture also includes a paint receiving element connected to the fixing assembly, which is positioned between the hood and fenders to receive electrophoretic paint leaking from the hood.

[0005] In one embodiment of this application, the hood and fender are both painted components, and the support member is an unpainted component; wherein, when the paint receiving member is disposed between the hood and the fender, the paint receiving member is disposed at intervals from the hood and the fender respectively.

[0006] In one embodiment of this application, a support member is disposed on the hood; wherein, when the hood is in the closed state, the support member is supported between the hood and the fender, so that the hood and the fender are spaced apart from each other.

[0007] In one embodiment of this application, the fixing component includes: a kit having a fixing groove inside for accommodating a support member; and a fixing member disposed on the kit for fixing the support member in the fixing groove.

[0008] In one embodiment of this application, the fastener is threadedly connected to the kit, and at least a portion of the fastener is embedded in the fixing groove. The fastener is configured to engage with the support member by engaging with the groove wall of the fixing groove, so as to fix the support member in the fixing groove.

[0009] In one embodiment of this application, the fastener includes: a fixing part that is threadedly connected to the kit and at least a portion of the fixing part is embedded in a fixing groove; and a control part connected to the end of the fixing part away from the kit, the control part being configured for a user to control to rotate the fixing part, thereby adjusting the length of the portion of the fixing part embedded in the fixing groove.

[0010] In one embodiment of this application, the paint receiving component has a first paint receiving surface and a second paint receiving surface that are inclined to each other. The first paint receiving surface and the second paint receiving surface are used to receive electrophoretic paint leaking from the hood. When the paint receiving component is disposed between the hood and the fender, both the first paint receiving surface and the second paint receiving surface are inclined relative to the height direction of the vehicle.

[0011] In one embodiment of this application, the end of the paint receiving component away from the fixing component has a clearance groove.

[0012] In one embodiment of this application, the paint receiving fixture further includes a connector, through which the paint receiving component is connected to the fixing component.

[0013] Accordingly, this application also provides a painting system including a vehicle hood, fenders, and a paint receiving fixture as described in the above embodiments. The fixing components of the paint receiving fixture are fixed to the vehicle's support, and the paint receiving component is disposed between the hood and the fender to receive electrophoretic paint leaking from the hood.

[0014] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a paint receiving fixture and a painting system. The paint receiving fixture includes a fixing component and a paint receiving element. The paint receiving element is positioned between the hood and the fender to receive electrophoretic paint leaking from the hood. The paint receiving element can accurately receive the electrophoretic paint leaking from the hood, preventing paint drips onto the fender surface, thereby reducing the risk of electrophoretic flow marks on the fender. Furthermore, the fixing component of this application is used to fix the paint receiving element to a support member of the vehicle, enabling the paint receiving element to be installed between the hood and the fender. The support member is configured to support the hood and the fender when the hood is closed. In other words, this application uses the support member that supports the hood and fender as the fixing point of the paint receiving fixture, eliminating the need for an additional installation structure, thus simplifying the installation method of the paint receiving fixture.

[0025] This application provides a paint receiving fixture and a coating system, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0026] To address the technical problem of electrophoretic flow marks easily forming on fenders in existing technologies, one embodiment of this application provides a paint receiving fixture. This paint receiving fixture includes a fixing component for fixing to a support member of the vehicle. The support member is configured to support the hood and the fender of the vehicle when the hood is closed. The paint receiving fixture also includes a paint receiving element connected to the fixing component, which is disposed between the hood and the fender to receive electrophoretic paint leaking from the hood. This will be described in detail below.

[0027] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of an embodiment of the coating system of this application. Figure 2 yes Figure 1 The diagram shows the structure of area A of the coating system. Figure 3 This is a schematic diagram of an embodiment of the paint receiving fixture installed on the machine cover.

[0028] In one embodiment, the painting system includes a vehicle hood 22, a fender 23, and a paint receiving fixture 10. The paint receiving fixture 10 is fixed to a support 21 of the vehicle and is disposed between the hood 22 and the fender 23 to receive electrophoretic paint leaking from the hood 22.

[0029] Please refer to the following: Figure 4 , Figure 4 This is a schematic diagram of the structure of an embodiment of the paint receiving fixture of this application.

[0030] In one embodiment, the paint receiving fixture 10 includes a fixing assembly 11 for fixing to a support member 21 of the vehicle. The support member 21 is configured to support the hood 22 and the fender 23 of the vehicle when the hood 22 is closed. The paint receiving fixture 10 also includes a paint receiving element 12 connected to the fixing assembly 11, which is positioned between the hood 22 and the fender 23 to receive electrophoretic paint leaking from the hood 22.

[0031] In this embodiment, the paint receiving component 12 is positioned between the hood 22 and the fender 23 to receive the electrophoretic paint leaking from the hood 22. The paint receiving component 12 accurately receives the leaking paint, preventing paint drips onto the surface of the fender 23 and thus reducing the risk of electrophoretic flow marks on the fender 23. In the prior art, for the problem of electrophoretic flow marks on the fender, vehicle manufacturers typically set up grinding lines to manually grind the flow marks. If the base coat is exposed during grinding, an additional primer repair process is required. This method not only increases the cost of sandpaper and manpower, but also severely affects the service life of the paint film and significantly reduces its corrosion resistance once the base coat is exposed. Alternatively, the electrophoretic line can be modified to include spray cleaning to remove residual electrophoretic liquid accumulated in the structure. However, this method requires the liquid-accumulating structure to be exposed as much as possible for effective spraying and is generally suitable for electrophoretic flow mark defects in the rear drainage channel area. Another method is to optimize the body structure so that the liquid flows into the body cavity, thus avoiding surface flow marks. However, this method has high requirements for the body structure, and the design of the inner hood panel structure is often not able to meet the requirements due to the influence of the appearance.

[0032] Furthermore, in this embodiment, the fixing component 11 is used to fix the support member 21 of the vehicle, so that the paint receiving fixture 12 can be installed between the hood 22 and the fender 23. The support member 21 is configured to support the hood 22 and the fender 23 of the vehicle when the hood 22 is in the closed state. In other words, this embodiment uses the support member 21 that supports the hood 22 and the fender 23 as the fixing point of the paint receiving fixture 10. The support member 21 is an existing structure of the vehicle, and there is no need to set up an additional installation structure to install the paint receiving fixture 10, which helps to simplify the installation method of the paint receiving fixture 10.

[0033] It should be noted that both the hood 22 and fender 23 are painted components, while the support member 21 is an unpainted component. The support member 21 is typically located inside the vehicle and does not affect its appearance; therefore, it does not require painting. Specifically, the support member 21 is located on the hood 22. When the hood 22 is closed, the support member 21 supports the hood 22 and fender 23, ensuring they are spaced apart and preventing them from bumping into each other. During the electrophoretic coating process of the hood 22 and fender 23, the hood 22 is not fully closed. At this time, the support member 21 on the hood 22 is spaced apart from the fender 23, allowing the paint receiving fixture 10 to be fixed to the support member 21. In this embodiment, using the support member 21 as the fixing point for the paint receiving fixture 10 minimizes the risk of the paint receiving fixture 10 damaging the paint film on the painted components (e.g., the hood 22 and fender 23). When the paint receiving component 12 is positioned between the hood 22 and the fender 23, it is spaced apart from both the hood 22 and the fender 23 to prevent the paint receiving fixture 10 from causing physical damage (such as scratches) or chemical contamination to the paint film on the hood 22 and the fender 23 during installation / use, thus ensuring the quality of the paint film on the surfaces of the hood 22 and the fender 23. Furthermore, the paint receiving component 12 does not affect the paint adhesion on the hood 22 and the fender 23 during the electrophoresis process, while providing an independent space for collecting leaked paint, ensuring that leaked paint is effectively collected and does not remain in the gaps.

[0034] In one embodiment, the fixing component 11 includes a kit 111 and a fastener 113. The kit 111 has a fixing groove 112 inside, which is used to receive the support member 21. The fastener 113 is disposed in the kit 111 and is used to fix the support member 21 in the fixing groove 112.

[0035] In this embodiment, the fixing groove 112 of the kit 111 is used to accommodate the support member 21, and the fixing member 113 provides a reliable clamping force to ensure that the paint receiving fixture 10 does not shift during electrophoresis, thus ensuring the positional stability of the paint receiving member 12. Furthermore, the design of the kit 111 with the fixing member 113 supports quick assembly and disassembly of the paint receiving fixture 10, facilitating direct installation on existing vehicle models and improving the engineering practicality of the paint receiving fixture 10.

[0036] Specifically, the fastener 113 is threadedly connected to the kit 111, and at least a portion of the fastener 113 is embedded in the fixing groove 112. The fastener 113 is configured to engage with the support member 21 against the groove wall of the fixing groove 112, thereby fixing the support member 21 in the fixing groove 112. In this embodiment, the depth of embedding in the fixing groove 112 is adjusted by rotating the fastener 113 to accommodate support members 21 of different sizes (such as thickness and cross-sectional shape), improving the versatility of the paint receiving fixture 10. Furthermore, the self-locking characteristic of the threaded connection ensures that the fastener 113 does not loosen under conditions such as vibration and high temperature (drying oven environment), ensuring stability and reliability, and guaranteeing the long-term stable operation of the paint receiving fixture 10 under complex working conditions.

[0037] For example, kit 111 can be machined from a single 25.5mm*14mm*14mm steel plate, with the specific dimensions adjusted according to the support 21 to ensure compliance with process requirements. An M6 threaded through hole can be drilled at one end of kit 111 to lock in place with fastener 113, ensuring proper installation. Fastener 113 includes a fixing part 114 and a control part 115. The fixing part 114 is threadedly connected to kit 111, and at least a portion of the fixing part 114 is embedded in the fixing groove 112. The control part 115 is connected to the end of the fixing part 114 away from kit 111, and is configured for user operation to rotate the fixing part 114, thereby adjusting the length of the portion of the fixing part 114 embedded in the fixing groove 112. Fastener 113 can be constructed by welding an M6*80mm threaded rod to a round steel bar with a diameter of 6mm and a length of 66mm.

[0038] In one embodiment, the paint receiving component 12 has a first paint receiving surface 121 and a second paint receiving surface 122 that are inclined to each other. When the paint receiving component 12 is disposed between the hood 22 and the fender 23, both the first paint receiving surface 121 and the second paint receiving surface 122 are inclined relative to the height direction Z of the vehicle, such as... Figure 5 As shown. The first paint receiving surface 121 and the second paint receiving surface 122 are used to receive the electrophoretic paint leaking from the cover 22.

[0039] Through the above-described method, this embodiment, by reasonably setting the paint receiving component 12, can cover the multi-angle paint leakage paths between the hood 22 and the fender 23, expanding the paint receiving area. Furthermore, the guide design of the first paint receiving surface 121 and the second paint receiving surface 122 can guide the electrophoretic paint to converge along the receiving surface to the bottom of the paint receiving component 12, preventing paint from accumulating and dripping on the surface of the paint receiving component 12, while facilitating subsequent centralized cleaning, improving the efficiency and convenience of paint leakage collection. In this embodiment, the size of the paint receiving surface of the paint receiving component 12 can be appropriately adjusted according to the area where flow marks occur, ensuring that it does not interfere with the vehicle body, and that the paint receiving surface ensures that liquid drips into the paint receiving component 12 and does not flow to the fender 23.

[0040] Furthermore, the end of the paint receiving component 12 away from the fixing component 11 has a relief groove 123 to avoid the protruding structure on the hood 22 or fender 23, ensuring that the paint receiving fixture 10 can be fully installed in place, avoiding the paint receiving position shift caused by component interference, and ensuring the compatibility of the paint receiving fixture 10 with the vehicle body structure.

[0041] In one embodiment, the paint receiving fixture 10 further includes a connector 13, through which the paint receiving component 12 is connected to the fixing component 11. The cross-sectional area of ​​the connector 13 is smaller than that of the paint receiving component 12, which reduces the overall volume of the paint receiving fixture 10 while connecting the paint receiving component 12 and the fixing component 11, making it easier to fit in the narrow area between the hood 22 and the fender 23, thus saving material for the connector 13. The cross-sections of the connector 13 and the paint receiving component 12 should be understood as their cross-sections perpendicular to the relative directions of the paint receiving component 12 and the fixing component 11. The connector 13 can be welded to the paint receiving component 12 and the fixing component 11 respectively, etc., and is not limited here.

[0042] In summary, this application provides a paint receiving fixture and a painting system. The paint receiving fixture includes a fixing component and a paint receiving element. The paint receiving element is positioned between the hood and the fender to catch electrophoretic paint leaking from the hood. The paint receiving element can accurately catch the electrophoretic paint leaking from the hood, preventing paint drips onto the fender surface and thus reducing the risk of electrophoretic flow marks on the fender. Furthermore, the fixing component is used to fix the paint receiving element to a support member of the vehicle, enabling the paint receiving element to be installed between the hood and the fender. The support member is configured to support the hood and the fender when the hood is closed. In other words, this application uses the support member that supports the hood and fender as the fixing point for the paint receiving fixture, eliminating the need for an additional mounting structure and thus simplifying the installation method.

[0043] The paint splicing fixture of this application has a simple structure, with a single point of contact between the fixture and the hood, reducing the number of contact points and thus lowering the risk of paint film damage. Furthermore, the fixture is simple to manufacture, requires minimal welding, saves materials, and reduces manufacturing costs. Installation is convenient and time-saving; the fit between the fasteners and the kit easily meets installation requirements, improving production cycle time and thus satisfying production demands. The fixture is compact, lightweight, inexpensive to purchase, and easy to transport for repeated use on-site; it requires no cleaning; and it can be used on all vehicle models produced in the factory.

[0044] The above provides a detailed description of the paint receiving fixture and coating system provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
