[0002] In the process of automobile manufacturing, many parts need to be sprayed to extend their service life. For example, the rear subframe is one of the key parts that needs to be sprayed. In order to ensure the accuracy and reliability of the subsequent assembly of various parts, the connection holes on the parts and the mating surfaces around the connection holes must be protected before spraying to prevent the ink from covering the connection holes and mating surfaces during the spraying process.

[0003] At present, during the spraying process, stickers are usually pasted on the mating surface to cover the mating surface and the connection hole in the middle of the mating surface, and then the component is sprayed as a whole. After spraying, the stickers are removed. However, due to the large size of the stickers, it is easy to cover the spraying surface around the small connection hole when protecting it. The covered spraying surface needs to be repainted later, which is inconvenient to operate and has low work efficiency.

[0004] Therefore, the above problems need to be solved urgently. Summary of the invention

[0042] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0043] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0044] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0045] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0046] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0047] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0048] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0049] See also Figures 1 to 5 This embodiment provides a spray protection device for protecting the connection hole of component 100 and the mating surface around the connection hole. The spray protection device includes a protective film 1, a plug 2 and a detection mechanism. In this embodiment, component 100 is described by taking the rear subframe as an example. Correspondingly, the connection hole is a threaded hole, a pin hole or other hole used for connection on the rear subframe, which will not be described in detail.

[0050] Specifically, the protective film 1 is arranged in a circular shape, and an adhesive is applied to the back of the protective film 1 so that the protective film 1 can be adhered to the mating surface. The plug 2 is configured to block the connection hole. The total number of protective films and plugs 2 is set corresponding to the number of connection holes, and each connection hole is correspondingly provided with a protective film 1 or a plug 2. The detection mechanism is arranged on one side of the component 100, and the detection mechanism is configured to detect whether all the connection holes of the component 100 are installed with protective films 1 or plugs 2.

[0051] With such arrangement, small connection holes that cannot be protected by the protective film 1 can be sealed by the plug 2, thereby achieving comprehensive protection of the component 100. Compared with the method of only using stickers for protection in the prior art, there is no need to subsequently repaint the sprayed surface covered around the small connection hole, which is easy to operate and helps to improve work efficiency.

[0052] Generally speaking, in order to prevent the connection holes from being unprotected, all the connection holes usually need to be checked again before spraying. It is understandable that the detection mechanism detects whether all the connection holes of the component 100 are installed with protective films 1 or plugs 2. Compared with the manual detection method in the prior art, the detection efficiency is high and the labor intensity of the staff can be reduced.

[0053] It is worth noting that many components 100 need to be sprayed multiple times, and each time after spraying, they need to be baked to solidify the ink. Therefore, in this embodiment, the protective film 1 is made of a high temperature resistant material, so as to improve the applicability of the spray protection device. It should be noted that the high temperature material can be selected according to actual use requirements, such as polyethylene terephthalate (PET).

[0054] During the actual spraying process, the sprayed ink will completely cover the surface of the protective film 1, making it very difficult to peel off the protective film 1. It often requires a tool such as a blade to peel it off, which not only wastes time, but also easily causes scratches on the component 100. To avoid this problem, in the present embodiment, a hand-held portion 11 is provided on the protective film 1. With this arrangement, the operator can peel off the protective film 1 by grasping the hand-held portion 11, which can further improve the convenience of operation. Furthermore, the hand-held portions 11 between any two adjacent protective films 1 are connected. With this arrangement, the two protective films 1 can be peeled off together, which is more efficient.

[0055] In order to allow the protective film 1 to be accurately adhered to the mating surface, an observation hole 12 is opened in the middle of the protective film 1 so that the operator can observe the position of the connecting hole through the observation hole 12. It should be noted that in the actual spraying process, whether manual spraying or automatic spraying, the position of the protective film 1 and the plug 2 will be avoided, that is, the spraying path will not pass through the position of the protective film 1 and the plug 2, so that there will be no situation where the ink contaminates the connecting hole through the observation hole 12.

[0056] Generally speaking, both sides of the connection hole need to be blocked. Therefore, in this embodiment, the plug 2 includes a first blocking member 21 and a second blocking member 22. The first blocking member 21 can be embedded in and block one side of the connection hole, and the second blocking member 22 can be embedded in and block the other side of the connection hole. The first blocking member 21 and the second blocking member 22 can be detachably connected in the connection hole. It can be understood that the first blocking member 21 and the second blocking member 22 are connected to each other, which can prevent the first blocking member 21 and the second blocking member 22 from loosening or even falling off during the spraying or transportation process, thereby helping to ensure the spraying quality.

[0057] Specifically, the first blocking member 21 includes a first picking portion 211, a first elastic telescopic portion (not shown in the figure) and a first blocking portion 212. The first elastic telescopic portion is arranged on the first picking portion 211. The first blocking portion 212 is connected to the side of the first elastic telescopic portion away from the first picking portion 211, and the first blocking portion 212 can be partially embedded in the connecting hole. The second blocking member 22 includes a second picking portion, a second elastic telescopic portion (not shown in the figure) and a second blocking portion 222. The second elastic telescopic portion is arranged on the second picking portion. The second blocking portion 222 is connected to the side of the second elastic telescopic portion away from the second picking portion, and the second blocking portion 222 can be partially embedded in the connecting hole and fit and buckle with the first blocking portion 212.

[0058] It can be understood that the first elastic telescopic member and the second elastic telescopic member push the first blocking portion 212 and the second blocking portion 222 against each other, so that the first blocking portion 212 and the second blocking portion 222 can be more securely fastened to the ground, thereby further preventing the first blocking portion 21 and the second blocking portion 22 from loosening or even falling off during spraying or transportation.

[0059] In this embodiment, the first blocking portion 212 is slidably sleeved on the first taking portion 211, and the first blocking portion 212 is provided with a receiving groove, the first elastic telescopic portion is received in the receiving groove, and the two ends of the first elastic telescopic portion are respectively connected to the first taking portion 211 and the bottom wall of the receiving groove to push the first blocking portion 212 to slide. Similarly, the installation method of the second elastic telescopic member is consistent with the installation method of the first elastic telescopic member, so it is not described in detail.

[0060] It should be noted that the first elastic telescopic part and the second elastic telescopic part can select any elastic telescopic structure in the prior art, such as a telescopic spring, a disc spring, etc., and this embodiment does not make specific requirements and restrictions on this. It should also be noted that the buckle structure of the first blocking member 21 and the second blocking member 22 can refer to the buckle structure of snap buttons in the field of clothing.

[0061] The detection mechanism also includes a bracket 3 and a detection member 4. The detection member 4 is arranged on the bracket 3, and the number of the detection members 4 corresponds to the number of connecting holes, and each detection member 4 is configured to detect whether a protective film 1 or a plug 2 is installed on the corresponding connecting hole. It should be pointed out that the structure of the bracket 3 is customized according to the component 100 and will not be described in detail. Specifically, the detection member 4 includes a detection camera 41 and a fill light 42. The detection camera 41 is used to collect images at the connecting hole, and the fill light 42 is used to illuminate the connecting hole. Such a setting helps to improve the accuracy of the detection. It should be noted that the detection camera 41 is a prior art, and this embodiment does not make any improvements to it itself, so it will not be repeated.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
