Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive testing technology, and in particular to a device that facilitates the testing of paint film thickness. Background Technology
[0002] During automobile manufacturing, PVC weld sealant is applied to the joints of the sheet metal or other areas to achieve waterproofing and corrosion protection. Then, paint is sprayed over the PVC weld sealant to enhance the car's appearance and provide an additional protective layer. Currently, most painting processes consist of three steps: applying the intermediate coat, applying the color coat, and applying the clear coat. However, it is crucial to ensure that the thickness of each coat is within certain requirements; otherwise, problems such as paint blistering and poor adhesion may occur.
[0003] Currently, the most common laboratory method for testing the thickness of three types of paint films is to use adhesive tape. First, tape is applied to three locations on the same test panel to cover different areas. Then, paint is sprayed onto the surface of the test panel and the tape. After each spray, a piece of tape is removed, and this process is repeated three times. After drying, the test panel is dried, and the thickness difference at different locations is calculated to determine the thickness of the three types of paint films. However, because the test panel is not fixed in place, excessive gas pressure from the spray gun can cause the test panel to move, resulting in uneven paint film thickness and low accuracy. Furthermore, since the test panel is wet, movement can contaminate other test panels, increasing experimental costs. In addition, the repeated application and removal of tape increases labor and time costs. If the tape has low adhesion, it may not bond firmly to the test panel, and the tape may even open due to the high gas pressure from the spray gun. If the tape has high adhesion, removing it while the test panel is wet is difficult, leading to low overall experimental efficiency. Utility Model Content
[0004] The main objective of this invention is to provide a device that facilitates paint film thickness detection. It avoids situations where excessive gas pressure at the spray gun nozzle causes the test plate to move, eliminates the need for repeated tape application and removal, reduces labor and time costs, and effectively improves experimental efficiency. This invention solves the technical problems of low accuracy in existing paint film thickness detection experiments due to test plate movement and the need for repeated tape application and removal, resulting in high experimental, labor, and time costs and low overall experimental efficiency.
[0005] To achieve the above objectives, this utility model proposes a device for facilitating paint film thickness detection, comprising:
[0006] Testing table, the testing table having a flat surface for placing the plate;
[0007] A pressure plate box is disposed above the plate placement plane and detachably connected to the testing table to press against the test plate located on the plate placement plane; at least one side of the pressure plate box is open, and a plurality of paint baffles are provided inside the pressure plate box, and the plurality of paint baffles can extend individually toward the open direction to be located above different positions of the test plate.
[0008] Optionally, connecting blocks are provided on both sides of the plate placement plane, and the connecting blocks are protruding relative to the plate placement plane; connecting ears are provided on both sides of the pressure plate box, and the connecting ears are disposed on the connecting blocks; a connecting bolt is provided between the testing table and the pressure plate box, and the stud of the connecting bolt passes through the connecting ear and is threadedly connected to the connecting block.
[0009] Optionally, two pressure plate boxes are provided, with the two pressure plate boxes located on opposite sides of the plate placement plane, and the openings of the two pressure plate boxes facing each other.
[0010] Optionally, the number of connecting blocks is four, and the four connecting blocks are located at the corners of the plate placement plane.
[0011] Optionally, both the connecting block and the connecting ear are square in shape, and the connecting block and the connecting ear are the same size.
[0012] Optionally, the pressure plate box is provided with a plurality of partitions to divide the pressure plate box into a plurality of cavities along the length of the pressure plate box, and each cavity is provided with at least three of the paint baffles.
[0013] Optionally, several of the partitions are evenly distributed inside the pressure plate box.
[0014] Optionally, several of the paint baffles are arranged side by side, and the several paint baffles are of the same size.
[0015] Optionally, a connecting rod is provided on the side of the pressure plate box opposite to the opening to push and pull the paint baffle. One end of the connecting rod passes through the pressure plate box and is connected to the end of the paint baffle away from the opening.
[0016] Optionally, the number of cavities is the same as the number of test plates.
[0017] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:
[0018] In this invention, the testing platform has a flat surface for placing the test plate. A pressure plate box is positioned above this surface and is detachably connected to the testing platform. The pressure plate box presses against the test plate on the flat surface, securing it in place and preventing movement due to excessive gas pressure from the spray gun nozzle. This results in uniform paint film thickness on the test plate, high accuracy of experimental results, and no contamination of other test plates, while also reducing experimental costs. At least one side of the pressure plate box is open, and several paint baffles are installed inside. These baffles can extend individually towards the open surface to occupy different positions on different test plates. This invention uses paint baffles instead of tape. During the experiment, the baffles can be pulled out or pushed in one by one according to actual experimental needs, eliminating the need for repeatedly applying and removing tape, reducing labor and time costs, and effectively improving experimental efficiency. This invention solves the technical problems of low accuracy in existing experiments for detecting paint film thickness due to the easy movement of the test plate, and the high experimental, labor, and time costs and low overall experimental efficiency caused by the need for repeated application and removal of tape.

[0030] This invention proposes a device for easy detection of paint film thickness.
[0031] In the embodiments of this utility model, such as Figures 1 to 6 As shown, the device for facilitating paint film thickness detection includes:
[0032] Testing table 1, testing table 1 has a plate for placing the plate;
[0033] The pressure plate box 2 is positioned above the plate placement plane 11 and is detachably connected to the testing table 1 to press against the test plate 3 located on the plate placement plane 11. At least one side of the pressure plate box 2 is open, and several paint baffles 21 are provided inside the pressure plate box 2. The several paint baffles 21 can extend individually toward the open direction to be positioned above different positions of the test plate 3.
[0034] In this invention, the testing platform 1 has a plate placement plane 11, and a pressure plate box 2 is disposed above the plate placement plane 11. The pressure plate box 2 is detachably connected to the testing platform 1 and can press against the test plate 3 located on the plate placement plane 11 to fix the test plate 3. This prevents the test plate 3 from moving due to excessive gas pressure at the spray gun nozzle. The paint film thickness of the test plate 3 is uniform, the experimental results are highly accurate, and it does not contaminate other test plates 3, resulting in low experimental costs. At least one side of the pressure plate box 2 is open, and several paint baffles 21 are provided inside the pressure plate box 2. Each paint baffle 21 can extend individually towards the open direction to be positioned above different test plates 3 at different locations. This invention uses paint baffles 21 instead of tape. During the experiment, the paint baffles 21 can be pulled out or pushed in one by one according to the actual experimental needs, eliminating the need to repeatedly apply and tear tape, reducing labor and time costs, and effectively improving experimental efficiency. This invention solves the technical problems of low accuracy of experimental results due to the easy movement of the test plate 3 in the existing experiment for detecting paint film thickness, and the need for repeated application and removal of tape, which leads to high experimental costs, labor costs, and time costs, and low overall experimental efficiency.
[0035] like Figure 1 and 2 As shown, in one embodiment of this application, connecting blocks 12 are provided on both sides of the plate placement plane 11, and the connecting blocks 12 are protruding relative to the plate placement plane 11; connecting ears 22 are provided on both sides of the pressure plate box 2, and the connecting ears 22 are disposed on the connecting blocks 12; a connecting bolt is provided between the testing table 1 and the pressure plate box 2, and the stud of the connecting bolt passes through the connecting ears 22 and is threadedly connected to the connecting blocks 12.
[0036] Connecting blocks 12 are provided on both sides of the plate placement plane 11, and connecting ears 22 are provided on both sides of the pressure plate box 2. The connecting ears 22 are located on the connecting blocks 12. Connecting bolts are provided between the testing table 1 and the pressure plate box 2. The connecting bolts pass through the connecting ears 22 and are threadedly connected to the connecting blocks 12, thereby enabling the pressure plate box 2 and the testing table 1 to be detachably connected.
[0037] Specifically, the connecting block 12 and the connecting ear 22 are respectively provided with corresponding through holes, and the stud of the connecting bolt passes through the through hole of the connecting ear 22 and is threadedly connected to the through hole of the connecting block 12.
[0038] In another embodiment of the present invention, a connecting nut is provided inside the connecting block 12, and the stud of the connecting bolt passes through the connecting lug 22 and connects with the connecting nut inside the connecting block 12.
[0039] In another embodiment of this utility model, connecting bolts can be omitted. Instead, a clamp can be used to hold the pressure plate box 2, the test plate 3, and the plate placement plane 11. The pressure plate box 2 presses against the test plate 3, which can also fix the test plate 3 and prevent the test plate 3 from moving due to excessive gas pressure at the nozzle of the spray gun.
[0040] like Figure 4 As shown, in one embodiment of this application, two pressure plate boxes 2 are provided, and the two pressure plate boxes 2 are located on opposite sides of the plate placement plane 11, with the openings of the two pressure plate boxes 2 facing each other.
[0041] Two pressure plate boxes 2 are set on opposite sides of the plate placement plane 11. This allows the two pressure plate boxes 2 to simultaneously press against both ends of the test plate 3, making the force on the test plate 3 more balanced and uniform during the experiment, thereby improving the accuracy and reliability of the experiment. When the openings of the two pressure plate boxes 2 are set opposite each other, the two pressure plate boxes 2 can also be used to conduct experiments simultaneously. For example, one pressure plate box 2 can be used to press against one end of a certain number of test plates 3, while the other pressure plate box 2 presses against one end of another equal number of test plates 3. This allows multiple test plates 3 to be tested simultaneously, greatly improving experimental efficiency.
[0042] like Figure 4 As shown, in one embodiment of this application, four connecting blocks 12 are provided, and the four connecting blocks 12 are located at the corners of the plate placement plane 11.
[0043] The number of connecting blocks 12 is four, which can be used to connect two pressure plate boxes 2. The four connecting blocks 12 are located at the corners of the plate placement plane 11, making the area of the plate placement plane 11 for placing the test plate 3 larger, so that more test plates 3 can be placed for experiments, improving experimental efficiency, and also making the device more aesthetically pleasing.
[0044] In another embodiment of this utility model, the test plate 3 is divided into two types: a long plate and a short plate. When the test plate 3 is a long plate, only two of its opposite connecting blocks 12 are used to connect it to one pressure plate box 2 to fix the long plate. When the test plate 3 is a short plate, two of its opposite connecting blocks 12 are connected to one pressure plate box 2 to fix one set of short plates; the other two opposite connecting blocks 12 are connected to another pressure plate box 2 to fix another set of short plates. In this way, two sets of short plates can be tested simultaneously, which greatly improves the experimental efficiency. Therefore, this utility model has high practicality.
[0045] like Figures 1 to 3 As shown, in one embodiment of this application, both the connecting block 12 and the connecting ear 22 are square in shape, and the connecting block 12 and the connecting ear 22 are the same size.
[0046] Both the connecting block 12 and the connecting ear 22 are square in shape and have the same size. This allows the connecting block 12 and the connecting ear 22 to be quickly aligned by aligning their edges. Furthermore, when the connecting block 12 and the connecting ear 22 are respectively provided with through holes for the connecting bolts to pass through, the through holes of the connecting block 12 and the connecting ear 22 can be quickly aligned, making it easy for the studs of the connecting bolts to pass through. This enables the quick installation of the pressure plate box 2 and also improves the overall aesthetics of the device.
[0047] like Figure 4 and 5 As shown, in one embodiment of this application, the pressure plate box 2 is provided with a plurality of partitions 23 to divide the pressure plate box 2 into a plurality of cavities 24 along the length direction, and each cavity 24 is provided with at least three paint baffles 21.
[0048] By setting up several partitions 23, the pressure plate box 2 can be divided into several cavities 24. Each cavity 24 can correspond to a test plate 3, which can effectively improve the experimental efficiency. Each cavity 24 is provided with at least three paint baffles 21, and these paint baffles 21 are located above different positions of the test plate 3. This can block at least three different positions of the test plate 3, thereby meeting the experimental requirements of spraying three or more paint films, and has high practicality.
[0049] like Figure 4 As shown, in one embodiment of this application, a plurality of partitions 23 are evenly distributed inside the pressure plate box 2.
[0050] When several partitions 23 are evenly distributed inside the pressure plate box 2, the size of each cavity 24 is the same, which not only facilitates mold production and management, but also makes the interior of the pressure plate box 2 neater and more beautiful.
[0051] like Figure 1 , 2 As shown in Figures 4 and 5, in one embodiment of this application, a plurality of paint baffles 21 are arranged side by side, and the plurality of paint baffles 21 are of the same size.
[0052] The arrangement of several paint baffles 21 side by side can improve the aesthetics of the cavity 24 and provide convenience for experimental operations. The paint baffles 21 are all the same size, so the uniform size of the paint baffles 21 can simplify the production process, facilitate inventory management, and reduce the difficulty of installing the paint baffles 21.
[0053] like Figure 1 and2 As shown, in one embodiment of this application, a connecting rod is provided on the side of the pressure plate box 2 opposite to the opening to push and pull the paint baffle 21. One end of the connecting rod passes through the pressure plate box 2 and is connected to the end of the paint baffle 21 away from the opening.
[0054] A connecting rod is provided on the side of the pressure plate box 2 opposite to the opening to make it easier to push and pull the paint baffle 21. The method of pushing and pulling the paint baffle 21 with the connecting rod is replaced by pushing and pulling the paint baffle 21 by hand, and the experimenter does not need to touch the paint baffle 21 with his / her hand, which effectively improves the convenience and efficiency of the experiment operation and can also increase the service life of the device.
[0055] like Figure 1 As shown, in one embodiment of this application, the number of cavities 24 is the same as the number of test plates 3.
[0056] The test board 3 and the cavity 24 are set up in a one-to-one correspondence. When the number of cavities 24 is the same as the number of test boards 3, each cavity 24 can be tested with the corresponding test board 3, so that multiple test boards 3 can be tested at the same time, which greatly improves the experimental efficiency.
[0057] The specific usage process of one embodiment of this utility model is as follows: Two connecting blocks 12 are first installed on both sides of the plate placement plane 11. Then, six test plates 3 are placed side by side on the plate placement plane 11 (each test plate 3 is coated with an electrophoretic layer, and all six test plates 3 are long plates). One end of the six test plates 3 is placed side by side between two opposing connecting blocks 12. After placing the test plates 3, the pressure plate box 2 is installed. The connecting blocks 12 are connected to the connecting ears 22 with connecting bolts. The pressure plate box 2 simultaneously presses against the six test plates 3, thus fixing all six test plates 3 on the plate placement plane 11. The position of each test plate 3 corresponds to the position of a cavity 24. Each cavity 24 is provided with three paint baffles 21, namely C1, C2, and C3. First, all the paint baffles 21 in each cavity 24 are pulled out. At this time, C1, C2, and C3 are located above different positions of the same test plate 3. Then, the intermediate layer is sprayed simultaneously on all six test panels 3. After spraying, all C3 layers are pushed in, followed by simultaneous spraying of the color paint. After spraying, all C2 layers are pushed in, and finally, clear varnish is sprayed simultaneously. After the painting is completed, the pressure plate box 2 is disassembled. At this point, on each test panel 3, the area covered by C1 has only one electrophoretic layer; the area covered by C2 has one electrophoretic layer and one clear varnish; the area covered by C3 has one electrophoretic layer, one clear varnish, and one color paint; and the uncovered area of test panel 3 has one electrophoretic layer, one clear varnish, one color paint, and one intermediate layer. The six test panels 3 are baked, and after baking, the film thickness at different locations on the test panels 3 is measured using a film thickness gauge. The thickness of the three paint films (intermediate layer, color paint, and clear varnish) can be obtained by the difference between the film thicknesses at different locations.
[0058] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
