[0034] With the development of the automobile industry, consumers are paying more and more attention to the refinement and personalization of automobile interior and exterior trims. As one of the most important factors affecting the style of automobile interior and exterior trims, the grain of decorative panels involves aesthetics, touch, and safety, and can reduce product appearance defects to a certain extent, improve the quality and value of interior and exterior trims, showing its important role in participating in market competition.
[0035] Dermatoglyphics refer to natural lines on the epidermis of organisms, usually on the surface of human or other animals such as cattle, deer, crocodiles, etc. It can also refer to the surface texture of plants such as tree epidermis, cross-section, leaves, etc. With the expansion of modern design concepts, it has developed to other natural or artificial surface textures, such as stone textures, fabric textures, electric spark textures, etc. Among them, the dermatoglyphics on decorative panels are also called bite patterns, which refer to the decoration on the surface of plastic products. Plastic products have different materials, different surface arrangements, organizations, and structures, so the roughness and hardness are different, which are manifested as different dermatoglyphics.
[0036] Before mass production of decorative plates with leather grain, it is usually necessary to prepare samples of decorative plates to test the effect of leather grain on the concealment of appearance defects of decorative plates. In the prior art, leather grain paint is sprayed on bare plates to simulate the appearance of decorative plates in leather grain state, thereby preparing samples of decorative plates. However, since the leather grain formed by spraying leather grain paint on bare plates is significantly different from the leather grain corresponding to the preset leather grain model, the leather grain formed on the sample prepared in this way is also significantly different from the leather grain formed on the mold after leather grain corrosion according to the preset leather grain model.
[0037] In order to solve the technical problem that the leather grain formed on the sample of the decorative board and the leather grain formed on the mold for preparing the decorative board in the above-mentioned prior art are greatly different, the embodiment of the present application provides a method for preparing the decorative board. Figure 1 and Figure 2a to Figure 2g , Figure 1 FIG. 1 is a schematic diagram of a process for preparing a decorative plate according to an embodiment of the present application. Figure 2a to Figure 2gThe schematic diagram of the preparation process of the decorative plate in the embodiment of the present application is shown. The preparation method of the decorative plate provided in the embodiment of the present application includes but is not limited to the following steps S101 to S104.
[0038] S101, according to the model of the decorative leather grain of the decorative board, selecting a target coiled material having the same leather grain model as the decorative leather grain model from a plurality of coiled materials having leather grains.
[0039] During the processing and forming of the decorative board, appearance defects such as white mist, flow marks, stress marks and weld lines may be formed in some areas of its surface, so leather grain can be used to cover the above appearance defects. Because different types of leather grains have different masking performance for appearance defects, the model of the decorative leather grain of the decorative board can be preset from various types of leather grains with market demand according to the type of appearance defects that are prone to occur during the processing and forming of the specific decorative board. Please refer to Table 1, which shows the models of common leather grains and some of their properties. It should be noted that the model of the decorative leather grain of the decorative board can also be a model other than that in Table 1, and the embodiments of the present application do not limit the specific model of the decorative leather grain of the decorative board.
[0040] Table 1
[0041] model Dermatoglyphic type Depth of skin texture Concealment of appearance defects 1 Fine skin wrinkles 0-60um Difference 3 Brushed 20-80um generally 4 Rough leather texture 80-150um good 5 Geometric pattern 80-150um good
[0042] According to the model of the decorative leather grain preset in the decorative board, a target coiled material having the same model of leather grain as the model of the decorative leather grain of the decorative board is selected from the plurality of coiled materials with leather grains. The model of leather grain on at least one of the plurality of coiled materials with leather grains is the same as the model of the decorative leather grain of the decorative board, thereby ensuring that a target coiled material meeting the conditions can be found from the plurality of coiled materials.
[0043] S102, according to the area of the decorative board having appearance defects, cutting a sheet suitable for the area from the target coil.
[0044] The area of the decorative sheet with appearance defects is the area on the decorative sheet that needs appearance review. On the sample of the decorative sheet for appearance review by the quality inspection department, at least the area corresponding to the area is formed with the same model as the decorative leather grain, so that the sample of the decorative sheet can be used as an example to test whether the concealing effect of the decorative leather grain on the appearance defects of the decorative sheet meets the standard during the appearance review. Therefore, the area with the leather grain formed on the sample of the decorative sheet can at least cover the area of the sample of the decorative sheet with appearance defects, that is, the sheet cut from the target coil can at least cover the area of the decorative sheet with appearance defects.
[0045] In some embodiments, the shape of the sheet is the same as the shape of the region with the appearance defect, and the size of the sheet is not smaller than the size of the region with the appearance defect, so that the area of the sheet is not smaller than the area of the region with the appearance defect.
[0046] In other embodiments, the shape of the sheet is a regular rectangle, and the length of a single side of the sheet is not less than the length of a single side of the region with the appearance defect. For example, the length of a single side of the sheet is 3 to 5 mm larger than the length of a single side of the region with the appearance defect, so that the area of the sheet is not less than the area of the region with the appearance defect. It should be noted that the length of a single side of the sheet may also be larger than the length of a single side of the region with the appearance defect by other dimensions, such as 2 mm larger. The embodiments of the present application do not limit the specific dimension by which the length of a single side of the sheet is larger than the length of a single side of the region with the appearance defect.
[0047] S103, pasting the sheet onto a mold for preparing the decorative board; wherein the position where the sheet is pasted onto the mold corresponds to the position where the region is located on the decorative board, and the leather grain on the sheet is exposed to the mold.
[0048] In some embodiments, the sheet can be attached to the mold for preparing the decorative board by coating one side of the sheet with adhesive; in other embodiments, the sheet can be attached to the mold for preparing the decorative board by attaching double-sided tape on one side of the sheet. Figure 2a As shown, Figure 2a This is a schematic diagram after applying adhesive on the sheet.
[0049] It should be noted that: if leather texture is formed on both sides of the sheet, the glue or double-sided tape can be set on any side of the sheet; if leather texture is formed on only one side of the sheet, the glue or double-sided tape can only be set on the side of the sheet without leather texture, so as to ensure that the leather texture on the sheet is exposed to the mold for preparing the decorative board, so that the leather texture on the sheet can be copied to the sample of the decorative board when the sample of the decorative board is formed by injection molding.
[0050] In order to ensure that the area with leather grain on the sample of the decorative board corresponds to the area with appearance defects on the decorative board, the position where the sheet is pasted on the mold for preparing the decorative board should correspond to the position where the area with appearance defects on the decorative board is located on the decorative board. Figure 2b As shown, Figure 2b A schematic diagram of pasting a sheet onto a mold for preparing a decorative board.
[0051] S104, closing the mold and then performing injection molding to form a sample of the decorative plate; wherein a leather grain having the same model as the decorative leather grain is formed on the sample.
[0052] The cavity and core of the mold for preparing the decorative board are combined to obtain a complete mold for preparing the decorative board. Figure 2c As shown, Figure 2c The figure is a schematic diagram of the mold cavity and core of the mold for preparing decorative panels after the mold is closed. After the mold is closed, injection molding is performed to form a sample of the decorative panel. Figure 2d As shown, Figure 2d The schematic diagram is a schematic diagram of a sample of a decorative plate formed by injection molding after the mold cavity and the mold core of a mold for preparing a decorative plate are combined. In which, a leather grain of the same model as the decorative leather grain is formed in the area of the sample of the decorative plate corresponding to the area where the decorative plate has appearance defects.
[0053] In the preparation method of the decorative board provided in the embodiment of the present application: before using a mold injection molding to form a sample of the decorative board, a sheet with the same grain model as the preset decorative grain model of the decorative board is pasted on the mold, and the position where the sheet is pasted on the mold corresponds to the position on the decorative board where the area with appearance defects of the decorative board is located, thereby copying the grain on the sheet to the area on the sample corresponding to the area with appearance defects of the decorative board, so that the grain formed on the sample is consistent with the preset decorative grain of the decorative board, reducing the difference between the grain formed on the sample of the decorative board and the grain formed on the mold for preparing the decorative board, and improving the accuracy of the appearance evaluation of the sample.
[0054] In some embodiments, before selecting a target coiled material having the same grain model as the decorative grain model from a plurality of coiled materials having grains according to the grain model of the decorative board in step S101, the method for preparing the decorative board in the embodiment of the present application further comprises the following steps:
[0055] Preparation of various coils;
[0056] Leather grain is formed on one side of each coil; wherein the model of the leather grain on each coil is different, and the model of the leather grain on at least one of the multiple coils is the same as the model of the decorative leather grain.
[0057] In some embodiments, the material of the coil can be metal, the coil can be a metal coil, and the sheet can be a metal sheet, such as a carbon steel coil and a carbon steel sheet. The method for preparing a variety of metal coils can refer to the method for preparing metal coils in the prior art, which will not be repeated here. It should be noted that the material of the coil may not be metal. It only needs to ensure that the material of the coil can withstand the temperature during injection molding and the leather grain on the coil will not deform at the temperature during injection molding. The embodiments of the present application do not limit the specific material of the coil. Among them, the specifications of the various coils can be different, and the width dimension of the coil is positively correlated with the thickness dimension of the coil. Please refer to Table 2, which is the specification data of the coil for reference.
[0058] Table 2
[0059] Serial number Metal sheet width (mm) Metal sheet thickness (mm) Metal sheet material 1 6 / 8 / 10 0.10～0.15 Carbon Steel 2 12 / 15 / 18 0.15～0.20 Carbon Steel 3 20 / 25 / 30 0.15～0.20 Carbon Steel
[0060] It should be noted that: the model of the leather grain on the same kind of coil is the same; the same kind of coil may include multiple coils with different specifications, the same kind of coil may also include multiple coils with partially the same specifications, and the same kind of coil may also include multiple coils with all the same specifications.
[0061] Leather grain is formed on one side of each coil, so that the model of the leather grain on each coil is different, and the model of the leather grain on at least one of the multiple coils is the same as the model of the decorative leather grain. The method of forming the leather grain on the coil may include one or more of wire drawing, embossing, sandblasting, etching and laser engraving. The method of forming the leather grain on each coil may be different, the method of forming the leather grain on each coil may be partially the same, and the method of forming the leather grain on each coil may be completely the same. The embodiment of the present application does not limit the specific method of forming the leather grain on the coil.
[0062] By prefabricating a variety of coils with different types of leather grains in advance, each time a decorative board with preset different types of decorative leather grains needs to be prepared, it is only necessary to select a target coil with the same leather grain model as the decorative leather grain model from the ready-made variety of coils with different types of leather grains, so that samples of the decorative board can be quickly prepared, thereby improving the efficiency of appearance review.
[0063] In some embodiments, a cavity surface is formed in the mold for preparing the decorative plate, and the cavity surface is a plane and / or a smooth curved surface; when the sheet is pasted on the mold for preparing the decorative plate in step S103, the method for preparing the decorative plate of the embodiment of the present application specifically includes the following steps:
[0064] The sheet is pasted on the cavity surface; wherein the sheet is formed with leather grain on the side facing away from the cavity surface.
[0065] The flat and smooth curved surface can ensure that the position where the sheet is pasted on the mold for preparing the decorative board is flat and without undulations, thereby ensuring that the sheet fits tightly to the mold and preventing the sheet from being washed away by the material flow during the subsequent injection molding process.
[0066] In some embodiments, after the mold is closed and injection molded in step S104 and before the sample of the decorative plate is formed, the method for preparing the decorative plate of the embodiment of the present application further includes the following steps:
[0067] The sheet covering after injection molding is removed.
[0068] Because the sheet is attached to the cavity surface of the mold for preparing the decorative board, the intermediate product after injection molding is covered with the sheet. Figure 2e As shown, Figure 2e This is a schematic diagram of the intermediate product after injection molding. At this point, the sheet covering the intermediate product needs to be removed. Figure 2f As shown, Figure 2f Schematic diagram of removing the sheet covering the intermediate product after injection molding. After removing the sheet from the intermediate product after injection molding, the leather grain under the sheet is exposed, and a sample of a decorative plate with leather grain is obtained. Figure 2g As shown, Figure 2g A schematic diagram of a sample of a decorative sheet with leather grain.
[0069] In some embodiments, after the mold is closed and injection molded to form a sample of the decorative plate in step S104, the method for preparing the decorative plate in the embodiment of the present application further includes the following steps:
[0070] Determine whether the sample has passed the appearance review;
[0071] If the sample passes the appearance review, a leather grain having the same model as the decorative leather grain is formed on the mold, and the decorative board is prepared using the mold having the leather grain formed thereon;
[0072] If the sample fails the appearance review, the sample shall be prepared after re-moulding, or the model of the decorative leather pattern shall be changed before preparing the sample.
[0073] When the samples of decorative panels are sent to the quality inspection department for appearance review, the quality inspection department will determine whether the samples of decorative panels have passed the appearance review according to the preset review standards. Please refer to Table 3, which is the standard for appearance review for reference.
[0074] Table 3
[0075]
[0076] If it is determined that the sample of the decorative plate has passed the appearance review, a leather grain of the same model as the decorative leather grain can be formed on the mold for preparing the decorative plate, and then the decorative plate is prepared by injection molding using the mold formed with the leather grain. The method of forming the leather grain on the mold for preparing the decorative plate may include one or more of sandblasting, etching, and laser engraving, but is not limited to sandblasting, etching, and laser engraving. The embodiment of the present application does not limit the specific method of forming the leather grain on the mold for preparing the decorative plate.
[0077] In some embodiments, in order to minimize the difference between the leather grain formed on the mold for preparing the decorative board and the leather grain formed on the target coil, the method of forming the leather grain on the mold for preparing the decorative board can be the same as the method of forming the leather grain on the target coil, so as to ensure to the greatest extent that the leather grain on the sample of the decorative board copied from the sheet is consistent with the leather grain on the mold for preparing the decorative board, thereby maximizing the accuracy of the appearance review of the decorative board samples.
