[0036] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0037] As Figures 1 to 8 shown, this embodiment provides a primer coating tooling for vehicle door seals, including a body 1, a positioning structure 2, and a track assembly 3. The positioning structure 2 is arranged on the outer peripheral edge of the body 1; at least two track assemblies 3 are detachably arranged on the positioning structure 2. The side of the track assembly 3 away from the positioning structure 2 has a primer coating surface 31, and the shapes of the primer coating surfaces of different track assemblies are different. The shape of the primer coating surface 31 of the track assembly installed on the positioning structure is adapted to the shape of the seal to be primer-coated. The primer coating device 7 performs primer coating operations on the seal to be primer-coated along the primer coating surface 31.

[0038] Using the primer coating tooling for vehicle door seals of the present utility model, by arranging the positioning structure 2 on the outer peripheral edge of the body 1 and detachably arranging the track assembly 3 on the positioning structure 2, and at the same time, the side of the track assembly 3 away from the positioning structure 2 has a primer coating surface 31. Since the shape of the primer coating surface 31 is adapted to the shape of the seal to be primer-coated, with such an arrangement, when performing primer coating operations, an appropriate track assembly 3 can be selected for adaptation according to the shape and size of the seal, improving the versatility of the primer coating tooling for vehicle door seals. Using the primer coating tooling for vehicle door seals provided by the present utility model is convenient to operate and has high efficiency.

[0039] In this embodiment, the shape of the body 1 matches the shape of the vehicle door.

[0040] In order to be able to adapt to seals to be primer-coated with different lengths, each track assembly 3 includes a plurality of track plates 32. The plurality of track plates 32 can all be detachably connected to the positioning structure 2, and the plurality of track plates 32 are abutted in sequence to form the primer coating surface 31. With such an arrangement, the length of the primer coating surface 31 can be adjusted according to the shape and size of the seal to be primer-coated, so as to select track plates 32 with corresponding lengths for better primer coating operations. The contact area between the primer coating surface 31 and the seal to be primer-coated can also be increased according to the actual situation, improving the fixing stability of the seal and preventing deviation or sliding during the primer coating process.

[0041] Among them, the materials of the track plate 32 include, but are not limited to, polyethylene, polytetrafluoroethylene, nylon and other materials. Specifically, polyethylene (PE) is a common plastic material with excellent chemical resistance, wear resistance and electrical insulation. However, due to its low surface polarity, it is not easy to chemically react or physically adsorb with adhesives, so it is not easy to stick; polytetrafluoroethylene (PTFE) is a special plastic material with excellent high temperature resistance, low temperature resistance, corrosion resistance, friction resistance and self-lubricating properties. However, due to its extremely low surface polarity, it hardly reacts with any substance, so it is not easy to stick; nylon (PA) is a common engineering plastic material with excellent mechanical strength, wear resistance, oil resistance and aging resistance. However, due to its low surface polarity and the presence of crystalline regions, it is not easy to form a good interfacial bond with adhesives, so it is not easy to stick. When the track plate 32 adopts the above materials, during the primer application operation, the track plate 32 is not easy to adhere to the sealant and difficult to separate, and the track plate 32 can be reused and is convenient for cleaning and maintenance.

[0042] As Figure 6 shown, there are 5 track plates 32, and the 5 track plates 32 are sequentially and abuttingly installed around the positioning structure 2.

[0043] Similarly, the number of track plates 32 can also be 6 or more. With such a setting, the 6 or more track plates 32 are sequentially and abuttingly installed around the positioning structure 2 to achieve the purpose of adapting to the sizes of different sealants to be primed in practice.

[0044] In this embodiment, in order to better position the track assembly 3, the track assembly 3 has a first positioning surface 321, and the positioning structure 2 has a second positioning surface 21. By the limiting cooperation between the first positioning surface 321 and the second positioning surface 21, the track assembly 3 can be positioned and its position can be limited. The installation convenience is improved.

[0045] Specifically, both the first positioning surface 321 and the second positioning surface 21 are set as stepped surfaces. Using stepped surfaces can position and limit the track assembly.

[0046] Specifically, the track assembly 3 includes a first plate body 322 and a second plate body 323 that are connected to each other. The length of the first plate body 322 is set to be greater than the length of the second plate body 323, so that a first positioning surface 321 can be formed between the first plate body 322 and the second plate body 323, and a primer application surface 31 can be provided on the side of the first plate body 322 away from the positioning structure 2.

[0047] Among them, the shape of the first plate body 322 is a "U" - shaped structure and is arranged around the outer periphery of the body 1.

[0048] Further, the primer coating tooling for vehicle sealing strips includes a first fastener. The first plate body 322 has a first mounting hole 3221, and the positioning structure 2 has a second mounting hole 22. In an embodiment of the present invention, the first fastener passes through the first mounting hole 3221 and the second mounting hole 22, so as to connect the first plate body 322 and the positioning structure 2. Among them, the first fastener is a bolt, the first mounting hole 3221 has internal threads, and the second mounting hole 22 is a square hole. In this way, during connection, the position of the track plate 32 can be finely adjusted, improving the applicability.

[0049] Specifically, the positioning structure 2 includes a first positioning block 23 and a second positioning block 24. The first positioning block 23 is connected to the outer peripheral edge of the body 1, and the second positioning block 24 is connected to the side of the first positioning block 23 away from the body 1. The length of the first positioning block 23 is set to be greater than the length of the second positioning block 24, so that a second positioning surface 21 can be formed between the first positioning block 23 and the second positioning block 24. Among them, the first positioning block 23 has the second mounting hole 22.

[0050] It should be noted that: the width of the first positioning block 23 is adapted to the width of the first plate body 322, and the width of the second positioning block 24 is adapted to the width of the second plate body 323.

[0051] Specifically, the primer coating tooling for vehicle sealing strips further includes a handle 4, and the handle 4 is detachably arranged on the body 1. The setting of the handle 4 facilitates the staff to grasp.

[0052] In this embodiment, there are two handles 4, which are arranged side by side on the body 1.

[0053] Among them, the primer coating tooling for vehicle sealing strips further includes a second fastener and a third fastener. The body 1 has a first assembly hole 11 and a second assembly hole 12 arranged at intervals. The first end of the handle 4 has a first connection hole 41, and the second end of the handle 4 has a second connection hole 42. The first assembly hole 11 and the first connection hole 41 can be threadedly matched through the second fastener, so as to connect the first end and the body 1; the second assembly hole 12 and the second connection hole 42 can be threadedly matched by using the third fastener, so as to connect the second end and the body 1.

[0054] In this embodiment, the primer coating tooling for vehicle sealing strips further includes a positioning hole 5 and an auxiliary hole 6 that are spaced apart on the body 1. Both the positioning hole 5 and the auxiliary hole 6 are in limit fit with the vehicle sheet metal part through positioning pins. The positions of the body 1, the positioning hole 5, and the auxiliary hole 6 and the vehicle sheet metal part are accurately positioned and fixed to ensure the accuracy and stability of the primer coating trajectory. The positioning hole 5 is an RPS positioning hole, which is a commonly used positioning method for automotive parts. Its principle is to use RPS points (Reference Point System points, that is, positioning reference points) to limit the six degrees of freedom of the part in space to determine its position. By inserting an RPS pin or other positioning tools into the RPS positioning hole and the vehicle sheet metal part, rapid docking and disassembly with the body 1 can be achieved.

[0055] The working process of the primer coating tooling for vehicle sealing strips of the present utility model is as follows:

[0056] When performing primer coating operation, first, the operator moves the body 1 to a predetermined position, and connects the body 1 with the vehicle sheet metal part by inserting positioning pins into the positioning hole 5 and the auxiliary hole 6, thereby limiting the position of the body 1 on the vehicle sheet metal part. The primer coating surface 31 on the side of the trajectory component 3 away from the positioning structure 2 is attached to the sealing strip to be primer coated. Since the primer coating surface 31 on the side of the trajectory component 3 away from the positioning structure 2 is adapted to the shape of the sealing strip to be primer coated, Figure 7 the primer coating equipment 7 performs primer coating operation between the primer coating surface 31 on the side of the trajectory component 3 away from the positioning structure 2 and the sealing strip to be primer coated. Using the primer coating tooling for vehicle sealing strips of the present utility model improves the qualified rate of the product. Among them, the primer coating equipment 7 can be a primer coating pen, a primer coating gun, etc. The primer coating equipment 7 is already prior art and will not be elaborated here.

[0057] The advantages of the primer coating tooling for vehicle sealing strips of the present utility model are as follows:

[0058] The primer coating equipment 7 performs primer coating operation between the primer coating surface 31 and the sealing strip. The primer coating equipment 7 can be a primer coating pen, a primer coating gun, etc. Since the primer coating surface 31 is adapted to the shape of the sealing strip, the primer coating operation can be carried out according to the trajectory of the sealing strip, thereby effectively controlling the trajectory and thickness of the primer coating glue line, improving the qualified rate of the product, and being able to adjust the position, quantity, thickness, and shape of the trajectory plate 32 according to the shape and specifications of the sealing strip to achieve primer coating with different trajectories and thicknesses, improving the applicability during primer coating operation of vehicle sealing strips with different specifications and reducing the cost.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
