Description

Technical Field

[0001] This utility model relates to the field of coating process technology. More specifically, it relates to a coating equipment. Background Technology

[0002] Currently, the mainstream coating process for electronic products (such as 3C products, i.e., computer, communication, and consumer electronics), building materials and decorative products, and automotive parts is to spray paint onto the surface of the product. To improve the leveling properties of the paint, the solvent content in the paint usually accounts for more than 70%. The spraying process generates a large amount of VOCs (volatile organic compounds) emissions, which is detrimental to environmental protection. In addition, the spraying process can only coat decorative layers with colors and patterns, and cannot coat functional layers with functions such as adjusting tactile feel and antibacterial properties, thus failing to achieve multi-functional coatings through the coating process. Utility Model Content

[0003] The purpose of this invention is to provide a coating device to solve at least one of the problems existing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model provides a coating equipment, including a first housing, a second housing, a vacuum device, an air inlet device, a curing device, a bearing mechanism, a first driving mechanism, and a second driving mechanism;

[0006] The first driving mechanism is used to drive the first housing and the second housing to close the mold to press the coating film. When the first housing and the second housing are closed, the first housing and the coating film form a first sealed cavity, and the second housing and the coating film form a second sealed cavity.

[0007] The vacuum pumping device is used to evacuate the first sealed cavity and the second sealed cavity respectively;

[0011] The curing device is used to apply curing conditions to the coating film so that the coating film is fixed on the surface of the product to be coated.

[0012] Optionally, the supporting mechanism avoids the bottom edge area of ​​the product to be coated, so that there is a gap between the bottom edge area of ​​the product to be coated and the supporting mechanism.

[0013] Optionally, the supporting mechanism includes a supporting platform and a supporting part located on the supporting platform for supporting the product to be coated, wherein the top surface of the supporting part facing the product to be coated matches the bottom surface of the product to be coated.

[0023] The beneficial effects of this utility model are as follows:

[0024] The coating equipment provided by this utility model performs appearance coating on products by applying a coating film containing dry coating decorative material to the product surface. The matching design of the top surface of the supporting mechanism facing the product with the non-planar bottom surface of the product allows for more stable support of the product, especially when there is a positive pressure difference between the first sealed cavity and the second sealed cavity. During curing, the coating film adheres tightly to the product surface. Even when the top and sides of the product are non-planar, such as when the top and sides include at least one (curved) depression and / or at least one (curved) convexity, the coating film can still adhere tightly to the top and sides of the product based on the positive pressure difference between the first sealed cavity and the vacuum of the second sealed cavity after the air pressure is increased by the air intake device, avoiding the formation of steps and wrinkles, and ensuring the appearance quality of the coated product.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] An embodiment of this utility model provides a coating equipment, including a first housing, a second housing, a vacuum device, an air inlet device, a curing device, a bearing mechanism, a first driving mechanism, and a second driving mechanism;

[0039] The first driving mechanism is used to drive the first housing and the second housing to close the mold to press the coating film. When the first housing and the second housing are closed, the first housing and the coating film form a first sealed cavity, and the second housing and the coating film form a second sealed cavity.

[0040] The vacuum pumping device is used to evacuate the first sealed cavity and the second sealed cavity respectively;

[0041] The supporting mechanism is placed in the second sealed cavity to support the product to be coated. The bottom surface of the product to be coated facing the supporting mechanism is not planar, and the top surface of the supporting mechanism facing the product to be coated matches the bottom surface of the product to be coated.

[0042] The second driving mechanism is used to drive the carrying mechanism to move the product to be coated toward the coating film, so that the product to be coated comes into contact with the coating film;

[0043] The air intake device is used to increase the air pressure into the first sealed cavity, so that the coating film adheres to the product to be coated.

[0044] The curing device is used to apply curing conditions to the coating film so that the coating film is fixed on the surface of the product to be coated.

[0045] The coating equipment provided in this embodiment performs surface coating on a product by applying a coating film containing a dry coating decorative material to the product surface. The matching design of the top surface of the supporting mechanism facing the product with the non-planar bottom surface of the product allows for more stable support of the product, especially when there is a positive pressure difference between the first sealed cavity and the second sealed cavity. During curing, the coating film adheres tightly to the product surface. Even when the top and sides of the product are non-planar, such as when the top and sides include at least one (curved) depression and / or at least one (curved) protrusion, the coating film can still adhere tightly to the top and sides of the product based on the positive pressure difference between the first sealed cavity and the vacuum of the second sealed cavity after the air intake device increases the air pressure in the first sealed cavity. This avoids the generation of steps and wrinkles, ensuring the appearance quality of the coated product.

[0046] In a specific example, for example Figure 1 The coating equipment shown includes a first housing 101, a second housing 102, a vacuum device 103, an air inlet device 104, a curing device 105, a supporting mechanism 106, a first driving mechanism 107, and a second driving mechanism 108, wherein...

[0047] The first housing 101 and the second housing 102 are both generally dome-shaped, with openings arranged opposite each other. The second housing 102 is fixed to the machine base as a fixed housing. The first drive mechanism 107 includes, for example, a motor or hydraulic device, a first driver 1071, and a telescopic first drive rod 1072. The first housing 101 is fixed to the first drive rod 1072 as a movable housing. The first driver 1071 drives (pulls) the first housing 101 away from the second housing 102 by driving the first drive rod 1072. Figure 1 The upward movement of the first housing 101 and the second housing 102 is used to open the mold and drive (push) the first housing 101 towards the second housing 102. Figure 1 The movement (in the downward direction) is used to achieve mold closing between the first housing 101 and the second housing 102.

[0048] When the first drive mechanism 107 drives the first housing 101 to move away from the second housing 102 to achieve the mold opening of the first housing 101 and the second housing 102, and the coating equipment is in the mold opening state, the operations of placing the product 801 to be coated on the support mechanism 106 in the receiving cavity formed by the second housing 102, laying the coating film 901 flat on the opening of the second housing 102, and taking out the product 801 after the curing process can be performed. The opening edges of the first housing 101 and the second housing 102 can be provided with sealing clamping parts made of, for example, rubber material, to more stably support the coating film 901 and to more tightly clamp and fix the coating film 901 after the first housing 101 and the second housing 102 are closed.

[0049] Among them, for example Figure 1 As shown, the central area of ​​the bottom surface of the product 801 to be coated facing the support mechanism 106 has a curved concave surface, and the top surface of the support mechanism 106 facing the product 801 to be coated forms a curved protrusion to match it, so that the support mechanism 106 can more stably support the product 801 to be coated and ensure the coating effect.

[0050] The first drive mechanism 107 drives the first housing 101 to move closer to the second housing 102 to achieve mold closing between the first housing 101 and the second housing 102 to press the coating film 901, thus positioning the coating equipment as follows: Figure 1 When the mold is closed as shown, the first housing 101 and the coating film 901 form a first sealed cavity, and the second housing 102 and the coating film 901 form a second sealed cavity.

[0051] For example Figure 1 As shown, the coating equipment also includes a main gas pipeline 1100. A first control valve 1101 is provided on the first gas pipeline connected to the first housing 101 and the main gas pipeline 1100. A second control valve 1102 is provided on the second gas pipeline connected to the second housing 102 and the main gas pipeline 1100. For example, a vacuum pump's vacuuming device 103 is provided on the third gas pipeline connected to the main gas pipeline 1100. For example, a high-pressure pump's air intake device 104 is provided on the fourth gas pipeline connected to the main gas pipeline 1100. A fourth control valve 1104 is provided on the fourth gas pipeline connected to the main gas pipeline 1100.

[0052] The vacuum device 103 can be activated by opening the first control valve 1101, the second control valve 1102, and the third control valve 1103 and closing the fourth control valve 1104, thereby evacuating the first sealed cavity formed by the first housing 101 and the coating film 901 in the mold-closed state and the second sealed cavity formed by the second housing 102 and the coating film 901.

[0053] The second drive mechanism 108 includes a second driver 1081, such as a motor or hydraulic device, and a telescopic second drive rod 1082. The drive rod 1082 extends into the receiving cavity formed by the second housing 102 through a sealing sleeve, and the support mechanism 106 is fixed to the second drive rod 1082. After vacuuming in the mold-closed state, the second driver 1081 can drive the second drive rod 1082 to move (push) the support mechanism 106, which carries the product 801 to be coated, located in the second sealed cavity formed by the second housing 102 and the coating film 901, towards the coating film 901. Figure 1 The material moves in an upward direction to bring the product 801 to be coated into contact with the coating film 901, for example, the top surface of the product 801 (the surface facing away from the support mechanism 106, i.e., the surface facing away from the support mechanism 106). Figure 1 The upper surface of the coating is coated with a thin film 901.

[0054] By controlling the opening of the first control valve 1101 and the fourth control valve 1104, and the closing of the second control valve 1102 and the third control valve 1103, and activating the air intake device 104, air pressure is increased into the first sealed cavity after the product 801 to be coated comes into contact with the coating film 901. This creates a positive pressure difference between the first sealed cavity and the vacuum-state second sealed cavity, causing the coating film 901 to tightly adhere to the top and sides of the product 801 to be coated. Although the product 801 to be coated... Figure 1 As shown, there are two curved recesses on its top surface. The positive pressure difference between the first sealed cavity and the second sealed cavity also allows the coating film 901 to adhere tightly to the top surface of the product 801 to be coated, without producing steps or wrinkles. In addition, the top surface of the support mechanism 106 facing the product 801 has a curved protrusion to match the curved recess in the central area of ​​the bottom surface of the product 801 facing the support mechanism 106. This design allows the support mechanism 106 to stably support the product 801 to be coated when there is a positive pressure difference between the first sealed cavity and the second sealed cavity, preventing the product 801 to be coated from shifting.

[0055] For example Figure 1As shown, the curing device 105 is disposed in the receiving cavity formed by the first housing 101, that is, disposed in the first sealed cavity formed by the first housing 101 and the coating film 901 in the molded state. When the coating film 901 is tightly attached to the top and side surfaces of the product 801 to be coated by positive pressure differential control, the curing device 105 applies curing conditions to the coating film 901 so that the coating film 901 is fixed on the surface of the product 801 to be coated, that is, the coating film 901 is fixed on the top and side surfaces of the product 801 to be coated.

[0056] In one possible implementation,

[0057] The air intake device is also used to increase the air pressure in the second sealed cavity;

[0058] The first driving mechanism is also used to drive the first housing and the second housing to open the mold.

[0059] After the coating film 901 is fixed on the surface of the product 801 to be coated, the second control valve 1102 and the fourth control valve 1104 can be opened while the first control valve 1101 and the third control valve 1103 are closed. The air intake device 104 is then activated to increase the air pressure in the second sealed chamber, making the air pressure in the second sealed chamber equal to that in the first sealed chamber. Then, the first drive mechanism 107 can drive the first housing 101 to move away from the second housing 102 to open the mold between the first housing 101 and the second housing 102, remove the product 801, and remove the redundant parts of the coating film 901 that are not fixed to the surface of the product 801 to obtain the coated product. Alternatively, the redundant parts of the coating film 901 that are not fixed to the surface of the product 801 can be removed first before removing the product 801.

[0060] In one possible implementation, the support mechanism avoids the bottom edge region of the product to be coated, so that there is a gap between the bottom edge region of the product to be coated and the support mechanism.

[0061] Continuing with the previous example, for example Figure 1 As shown, the support mechanism 106 avoids the bottom edge area of ​​the product to be coated. Figure 1As shown, the central area of ​​the bottom surface of the product 801 to be coated has a curved concave shape and the edge area is flat. The curved protrusion of the support mechanism 106 corresponds to the curved concave shape of the central area of ​​the bottom surface of the product 801 to be coated. The support mechanism 106 avoids the flat edge area of ​​the bottom surface of the product 801 to be coated, so that there is a gap between the edge area of ​​the bottom surface of the product 801 to be coated and the support mechanism 106. As a result, the first sealed cavity forms a positive pressure difference with respect to the second sealed cavity, which makes the coating film 901 closely adhere to the top surface, side surface and bottom edge area of ​​the product 801 to be coated. This causes the coating boundary of the coating film 901 to move inward from the bottom (outer) edge of the product 801 to be coated, which is more conducive to improving the visual effect of the top and side views, which are usually the main viewing angles, and ensuring the appearance quality of the coated product.

[0062] In one possible implementation, the support mechanism includes a support platform and a support portion located on the support platform for supporting the product to be coated, wherein the top surface of the support portion facing the product to be coated matches the bottom surface of the product to be coated.

[0063] In one possible implementation, the support unit is detachably connected to the support platform.

[0064] Continuing with the previous example, for example Figure 1 As shown, the support mechanism 106 includes a support platform 1061 and a support portion 1062 located on the support platform for supporting the product 801 to be coated. The top surface of the support portion 1062 facing the product 801 matches the bottom surface of the product 801 to be coated. Specifically, the central area of ​​the product 801 to be coated has a curved recess, and the bottom surface of the support portion 1062 is flat and has an overall curved convex shape. Thus, by designing the support mechanism with a separate support platform and a detachable connection, it is easy to replace the support portion 1062 to suit products of different shapes to be coated. After the coating film 901 is cured, the support portion 1062 can be removed together with the product 801. During removal, the support portion 1062 can be clamped to avoid damage to the appearance of the product 801.

[0065] In one possible implementation, the coating film is a thermosetting coating film, and the curing device includes at least one thermosetting device disposed within the first sealed cavity.

[0066] Furthermore, the curing device includes a plurality of thermosetting devices arranged in an array within the first sealed cavity.

[0067] In a specific example, the coating film 901 is a thermosetting coating film, and the cured adhesive layer in contact with the product 801 to be coated is also a thermosetting adhesive layer (curing conditions involve a chemical reaction after heating to a certain temperature to cure). In this case, for example... Figure 1As shown, the curing apparatus 105 includes a plurality of thermosetting devices, such as heating devices, arranged in an array within the receiving cavity formed by the first housing 101 (i.e., the first sealed cavity formed by the first housing 101 and the coating film 901 in the molded state). When the coating film 901 is tightly attached to the top and sides of the product 801 to be coated, the plurality of heating devices in the array generate heat to bring the coating film 901 to the chemical reaction temperature for curing. The arrangement of the plurality of thermosetting devices in an array allows for more uniform heating, which is beneficial for good curing. In addition, the plurality of heating devices in the array can preheat the coating film 901, which is a thermosetting coating film, after the first and second sealed cavities are evacuated and before the product 801 to be coated comes into contact with the coating film 901, to enhance the flowability of its thermosetting adhesive layer.

[0068] In one possible implementation, the coating film is a photocurable coating film, and the curing device includes at least one photocuring device disposed within the first sealed cavity.

[0069] Furthermore, the curing device includes multiple light curing devices arranged in an array within the first sealed cavity.

[0070] In a specific example, the coating film 901 is a photocurable coating film, and the cured adhesive layer in contact with the product 801 to be coated is also a photocurable adhesive layer (curing conditions are a chemical reaction occurring after exposure to light of a set wavelength to cure). In this case, for example, the photocurable coating film is an infrared photocurable coating film. Figure 1 The curing device 105 shown includes multiple light curing devices, such as infrared light sources, arranged in an array in the receiving cavity formed by the first housing 101 (i.e., the first sealed cavity formed by the first housing 101 and the coating film 901 in the molded state). When the coating film 901 is tightly attached to the top and side surfaces of the product 801 to be coated, the multiple infrared light sources arranged in an array emit infrared light to cure the coating film 901 by infrared light irradiation. The arrangement of multiple infrared light sources in an array can achieve more uniform infrared light irradiation, which is beneficial to good curing.

[0071] The coating equipment provided in the above embodiments will be further described below through its workflow. The workflow of the coating equipment provided in the above embodiments includes:

[0072] First, the product to be coated is placed on the carrier mechanism, and the coating film is placed between the first housing and the second housing.

[0073] In a specific example, the above process can be referred to as the material placement action, which realizes the preparation before painting, for example... Figure 2As shown, the process includes: the first drive mechanism 107 drives the first housing 101 to move away from the second housing 102 to achieve mold opening between the first housing 101 and the second housing 102. When the coating equipment is in the mold-open state, the product to be coated 801 is placed on the support mechanism 106 located in the receiving cavity formed by the second housing 102 (wherein, the curved concave area of ​​the center region of the bottom surface of the product to be coated 801 facing the support mechanism 106 corresponds to the curved convex area of ​​the support mechanism 106 facing the top surface of the product to be coated 801), and the coating film 901 is laid flat on the opening of the second housing 102 (so that the coating film 901 is located between the first housing 101 and the second housing 102). It should be noted that... Figures 2 to 6 The diagram shows that 901 is a thermosetting coating film and 105 includes multiple thermosetting devices.

[0074] Then, the first driving mechanism drives the first housing and the second housing to close the mold to press the coating film, so that the first housing and the coating film form a first sealed cavity, and the second housing and the coating film form a second sealed cavity.

[0075] Continuing with the previous example, the first drive mechanism 107 drives the first housing 101 to move closer to the second housing 102 to achieve mold closing between the first housing 101 and the second housing 102 to press the coating film 901 (after pressing, the coating film 901 is in a flat state), so that the coating equipment is in a state as follows. Figure 1 In the mold-closed state shown, the first housing 101 and the coating film 901 form a first sealed cavity, and the second housing 102 and the coating film 901 form a second sealed cavity.

[0076] Then, the vacuum pumping device evacuates the first sealed cavity and the second sealed cavity respectively.

[0077] Continuing with the previous example, such as Figure 3 As shown, by controlling the first control valve 1101, the second control valve 1102 and the third control valve 1103 to open and the fourth control valve 1104 to close, and by starting the vacuum pumping device 103, the first sealed cavity formed by the first housing 101 and the coating film 901 in the mold-closed state and the second sealed cavity formed by the second housing 102 and the coating film 901 are respectively evacuated.

[0078] Then, the second drive mechanism drives the carrier mechanism to move the product to be coated toward the coating film, so that the product to be coated comes into contact with the coating film.

[0079] Continuing with the previous example, such as Figure 4As shown, after vacuuming in the mold-closed state, the second drive mechanism 108 drives (pushes) the support mechanism 106, which carries the product 801 to be coated, located in the second sealed cavity formed by the second housing 102 and the coating film 901, to move closer to the coating film 901, so that the product 801 to be coated contacts the coating film 901, for example, the top surface of the product 801 (the surface facing away from the support mechanism 106, i.e.) Figure 4 The upper surface of the coating is coated with a thin film 901.

[0080] Furthermore, when the coating film 901 is a thermosetting coating film, after the vacuum device 103 evacuates the first and second sealing chambers and before the product to be coated 801 comes into contact with the coating film 901, the coating film 901, which is specifically a thermosetting device, can be preheated by the curing device 105 to enhance the flowability of its thermosetting adhesive layer.

[0081] Then, the air intake device increases the air pressure into the first sealed cavity, causing the coating film to adhere to the product to be coated.

[0082] Continuing with the previous example, such as Figure 5 As shown, after the product 801 to be coated comes into contact with the coating film 901, the first control valve 1101 and the fourth control valve 1104 are opened while the second control valve 1102 and the third control valve 1103 are closed, and the air intake device 104 is activated. This increases the air pressure in the first sealed cavity after the product 801 comes into contact with the coating film 901, creating a positive pressure difference between the first sealed cavity and the vacuum-state second sealed cavity, causing the coating film 901 to tightly adhere to the top and sides of the product 801. Wherein, as... Figure 5 As shown, the bearing mechanism 106 avoids the flat edge area of ​​the bottom surface of the product 801 to be coated, and there is a gap between the bottom edge area of ​​the product 801 to be coated and the bearing mechanism 106. As a result, the first sealed cavity forms a positive pressure difference with respect to the second sealed cavity, so that the coating film 901 is tightly attached to the top, side and bottom edge areas of the product 801 to be coated.

[0083] Then, a curing process is performed, in which the curing device applies curing conditions to the coating film to fix the coating film on the surface of the product to be coated.

[0084] Continuing with the previous example, such as Figure 5As shown, after the coating film 901 is tightly adhered to the top and side surfaces (and bottom edge area) of the product 801 to be coated by positive pressure differential control, the curing device 105 of the thermosetting device heats the coating film 901, which is a thermosetting coating film, so that the coating film 901 undergoes a chemical reaction and is cured, and fixed on the surface of the product 801 to be coated, that is, the coating film 901 is fixed on the top and side surfaces (and bottom edge area) of the product 801 to be coated.

[0085] Understandably, if the coating film 901 is a photocurable coating film, then in the curing process of step S60, the curing device of the photocuring apparatus emits light to irradiate the coating film 901, which is a photocurable coating film, so that the coating film 901 undergoes a chemical reaction and is cured, and fixed on the surface of the product 801 to be coated.

[0086] Then, the air intake device increases the air pressure into the second sealed chamber.

[0087] Then, the first drive mechanism drives the first housing and the second housing to open the mold so as to take out the product to be coated with the coating film fixed thereon.

[0088] Continuing with the previous example, after the coating film 901 is fixed on the surface of the product 801 to be coated, as follows: Figure 6 As shown, by controlling the second control valve 1102 and the fourth control valve 1104 to open and the first control valve 1101 and the third control valve 1103 to close, and by activating the air intake device 104, the air pressure in the second sealed chamber is increased, making the air pressure in the second sealed chamber equal to that in the first sealed chamber. Then, the first drive mechanism 107 drives the first housing 101 to move away from the second housing 102 to open the mold between the first housing 101 and the second housing 102, so that the product 801 with the coating film 901 fixed can be taken out. Figure 6 As shown, when the product 801 with the coating film 901 fixed is taken out, it is taken out together with the carrier part 1062.

[0089] In a specific example, the coating film includes a release carrier layer and a coating layer and a curing adhesive layer stacked on the release carrier layer. The workflow also includes: after removing the product with the coating film fixed on it, separating the release carrier layer of the coating film to obtain the coated product.

[0090] The coating film used includes a release carrier layer, such as... Figure 7As shown, the coating includes a release carrier layer 1001 and a coating layer 1002 and a curing adhesive layer 1003 stacked on the release carrier layer 1001. The curing adhesive layer 1003 is, for example, a thermosetting adhesive layer or a photocurable adhesive layer. When the curing adhesive layer 1003 is a thermosetting adhesive layer, the coating film can be called a thermosetting coating film; when the curing adhesive layer 1003 is a photocurable adhesive layer, the coating film can be called a photocurable coating film. Figure 7 As shown, the coating film including the release carrier layer also includes a functional layer 1004 located between the release carrier layer 1001 and the coating layer 1002, which has functions such as adjusting the feel and antibacterial properties. For example, as shown in 7, the functional layer 1004 and the coating layer 1002 can be directly bonded together. In addition, the functional layer 1004 and the coating layer 1002 can also be bonded and fixed together by a crosslinking layer.

[0091] For example Figure 7 In the coated film shown, including the release carrier layer, the release carrier layer 1001 is, for example, a high-elongation, high-ratio random copolymer of polyethylene and polypropylene with release force, prepared by a multilayer extrusion process. The coating layer 1002 serves as a decorative layer with color and pattern, providing a decorative effect for the product's appearance. The coating layer 1002 can be prepared on the functional layer 1004 or the crosslinking layer by printing, metal vapor deposition, or sputtering processes.

[0092] The coating equipment provided in this embodiment coats the product to be coated with, such as... Figure 7 The coating film including the release carrier layer shown can be called a transfer coating method. After the coating film including the release carrier layer is applied to the product surface, the functional layer 1004 and the coating layer 1002 remain on the product. The release carrier layer 1001 is then removed to obtain the product as shown. Figure 8 The product shown is after coating.

[0093] In a specific example, the coating film includes a carrier layer, a coating layer disposed on one side of the carrier layer, and a curing adhesive layer disposed on the other side of the carrier layer. The workflow also includes: after removing the product with the coating film fixed on it, cutting the coating film to obtain the coated product.

[0094] The coating film used includes a carrier layer, such as... Figure 9 As shown, the coating includes a carrier layer 1005, a coating layer 1002 disposed on one side of the carrier layer 1005, and a curing adhesive layer 1003 disposed on the other side of the carrier layer 1005. The curing adhesive layer 1003 is, for example, a thermosetting adhesive layer or a photocurable adhesive layer. When the curing adhesive layer 1003 is a thermosetting adhesive layer, the coating film can be called a thermosetting coating film; when the curing adhesive layer 1003 is a photocurable adhesive layer, the coating film can be called a photocurable coating film. Figure 9As shown, the coating film including the carrier layer also includes a functional layer 1004 located on the side of the coating layer 1002 opposite to the carrier layer 1005, which has functions such as adjusting touch and antibacterial properties. For example, as shown in 9, the functional layer 1004 and the coating layer 1002 can be directly bonded together. In addition, the functional layer 1004 and the coating layer 1002 can also be bonded and fixed together by a crosslinking layer.

[0095] For example, in the coating film including the carrier layer shown in Figure 9, the carrier layer 1005 is, for example, a copolymer of polypropylene, acrylonitrile, acrylate, styrene, butadiene, and ethylene oxide, and is prepared by an extrusion process. Both sides of the carrier layer 1005 have an adhesion function. The coating layer 1002 serves as a decorative layer with color and pattern, providing a decorative effect for the product's appearance. The coating layer 1002 can be prepared on the functional layer 1004 or the crosslinking layer by printing, metal vapor deposition, or sputtering processes.

[0096] The coating equipment provided in this embodiment coats the product to be coated with, such as... Figure 9 The coating film including the carrier layer shown can be called a lamination coating method. After the coating film including the carrier layer is applied to the product surface, a cutting process such as punching is performed, leaving the functional layer 1004, coating layer 1002, and carrier layer 1005 on the product, resulting in the following: Figure 8 The product shown is after coating.
