The light-transmitting adhesive film 102 may be made of a light-transmitting plastic material, and the light-transmitting adhesive film 102 may be shaped as a sheet, which should however not be construed as a limitation in the disclosure. The printing layer 104 may serve to decorate an automobile. The printing device may be a screen printing machine or the like. The printing layer 104 may be a color coating layer printed by the printing device on the light-transmitting adhesive film 102; for example, the printing layer is a yellow paint layer, a silver paint layer, or the like. In actual manufacturing, the printing layer 104 may be made of a light-transmitting coating. The printing layer 104 may also be a non-light-transmitting coating layer and may achieve a light transmission effect due to the small thickness of the non-light-transmitting coating layer. A mask plastic layer 106 is provided. The mask plastic layer 106 may be called MASK PET for short. PET is polyethylene terephthalate. The mask plastic layer 106 is adhered to the light-transmitting adhesive film 102, the mask plastic layer 106 covers the printing layer 104, and the printing layer 104 is sandwiched between the light-transmitting adhesive film 102 and the mask plastic layer 106.

In some embodiments, the light-transmitting adhesive film is made by co-pressing a PMMA plastic layer and a PC plastic layer. The PC plastic layer is made of a PC plastic material.
In some embodiments, a semi-permeable oil layer (not shown) is further formed between the light-transmitting adhesive film 102 and the printing layer 104, which should however not be construed as a limitation in the disclosure.
In step S200, at least one opening OP running through at least part of the light-transmitting element 110 is formed. In some embodiments, the step of forming the at least one opening OP may include providing a laser engraving device that laser-engraves the light-transmitting element 110 to form the at least one opening OP that runs through at least part of the light-transmitting element 110. The opening OP may be shaped in various forms; for example, the opening may be a curve, a plant pattern, an animal pattern, or the like. With the characteristics of laser engraving, diversified engraving and precision engraving may be achieved to improve manufacturing efficiency and yield of the opening OP.
In some embodiments, as shown in
In step S300, a sputtering layer 120 is formed by performing a sputtering process using a sputtering device, where the sputtering layer 120 is located in the opening OP to form an ornament unit 100. The sputtering device may sputter the sputtering layer 120 at the opening OP. The sputtering layer 120 is sputtered by the sputtering device, which, compared with conventional processes such as electroplating and vacuum-plating, can facilitate local coating and save processing and manufacturing costs. Moreover, the sputtering process greatly reduces the thickness of the sputtering layer 120, ensures a good light transmission effect of the sputtering layer 120, and improves a light transmission decoration performance of the automotive ornament. In addition, when the light-transmitting element 110 includes the mask plastic layer 106, during the sputtering process by the sputtering device, sputtering outside the opening can be prevented due to the coverage effect of the mask plastic layer 106, thus improving the sputtering yield. The sputtering layer 120 may be a silver layer, a white layer, or the like.
In some embodiments, after the sputtering process is performed by the sputtering device, the mask plastic layer 106may be removed, which should however not be construed as a limitation in the disclosure.
In some embodiments, in the method for manufacturing an automotive ornament according to the disclosure, the printing device prints and coats a printing layer 104 on the light-transmitting adhesive film 102, a mask plastic layer 106 is adhered to the light-transmitting adhesive film 102, the mask plastic layer 106 covers the light-transmitting printing layer 104, the mask plastic layer 106 is laser-engraved using a laser engraving device to form an opening running through the mask plastic layer 106, a sputtering layer 120 is sputtered at the opening by using a sputtering device, and after the sputtering process is by the sputtering device, the mask plastic layer 106 is removed, thus forming the ornament unit 100.
On the other hand, in the actual manufacturing process, the sputtering layer 120 located in the first opening OP1 (running through the mask plastic layer 106) may be a first sputtering layer, and the sputtering layer located in the second opening OP2 (running through the mask plastic layer 106 and the printing layer 104) may be a second sputtering layer. In some embodiments, the first sputtering layer and the second sputtering layer may exist individually, which should however not be construed as a limitation in the disclosure. The first sputtering layer and the second sputtering layer may also co-exist. When the first sputtering layer and the second sputtering layer co-exist, a light-emitting member may be added; as such, after light emitted by the light-emitting member is transmitted out of the light-transmitting adhesive film by the first sputtering layer and the second sputtering layer, light transmission of the entire automotive ornament is in a state of light and shade contrast. That is, the light transmitted out of the light-transmitting adhesive film by the first sputtering layer is semi-bright, and the light transmitted out of the light-transmitting adhesive film by the second sputtering layer is fully bright, thereby further improving the decoration performance of the automotive ornament.
After the automotive ornament is installed on an automobile, the automobile is decorated by the printing layer 104 during the day. At night, light emitted by the light-emitting member of the automobile may be transmitted out of the light-transmitting adhesive film 102 by the sputtering layer 120 to achieve a decoration effect for the automobile, which should however not be construed as a limitation in the disclosure.

Compared with the light-transmitting adhesive film 102 manufactured through bending and cutting processes, the light-transmitting adhesive film 102 may have the improved molding efficiency through the vacuum-forming process, thus improving manufacturing efficiency of the automotive ornament.
In some embodiments, a trimming unit (not shown) may also be provided. The trimming unit may trim residual materials on the sides and corners of the light-transmitting adhesive film 102 vacuum-formed by the vacuum-forming mold, and the printing device prints and coats the printing layer 104 on the light-transmitting adhesive film 102 trimmed by the trimming unit. Owing to the removal of the residual materials on the sides and corners of the light-transmitting adhesive film 102 by means of the trimming unit, the molding yield and the molding efficiency of the light-transmitting adhesive film 102 may be further enhanced.
In some embodiments, the trimming unit may include a ring strip disposed rotationally, a driving member configured to drive the ring strip to rotate, and a cutter disposed on the ring strip and located in the vacuum-forming mold.

Compared with the manner of moving the light-transmitting adhesive film out of the vacuum-forming mold for secondary positioning before trimming, positioning the light-transmitting adhesive film 102 by the vacuum-forming mold cavity improves trimming yield.
In some embodiments, the method for manufacturing the automotive ornament may further include following steps.

The sputtering layer 120 is then formed by performing a sputtering process on the light-transmitting plastic member by a sputtering device.
The light-transmitting plastic member is connected and secured to the ornament unit 100 by injection molding, which improves manufacturing efficiency of the automotive ornament and increases a connection between the light-transmitting plastic member and the ornament unit, ensuring that the two are firmly connected together, which should however not be construed as a limitation in the disclosure.
In some embodiments, the light-transmitting plastic member may cover the printing layer 104 and the sputtering layer 120 in the light-transmitting element 110.
In some embodiments, a light-emitting member (such as an LED) corresponding to the sputtering layer 120 may be preset in the injection molding mold cavity of the injection molding mold, and the light-emitting member may be connected and secured to the ornament unit 100 by the light-transmitting plastic member. Certainly, the light-transmitting plastic member may be made of a light-transmitting plastic material, the light-emitting member is mounted to a side of the light-transmitting plastic member away from the ornament unit 100, and light emitted by the light-emitting member passes through the light-transmitting plastic member and the sputtering layer 120 and is emitted through the light-transmitting adhesive film 102.
In some embodiments, the printing layer 104 may be further includes an anti-impact layer (not shown). When a melted plastic material of the injection molding mold is injected into the injection molding mold cavity and hits the printing layer 104, decorative patterns or colors of the printing layer 104 is protected from being damaged due to the anti-impact effect of the anti-impact layer. In addition, the printing layer 104 may have light-transmitting characters or patterns. Therefore, when there is no light source, decoration may be made by painting colors, and when there is an external light source, light may pass through the characters or patterns to display the characters or patterns, which should however not be construed as a limitation in the disclosure.
In some embodiments, the anti-impact layer may cover the opening, which should however not be construed as a limitation in the disclosure. In some other embodiments, the anti-impact layer may be laser-engraved by a laser-engraving device to form another opening, which runs through the anti-impact layer and may communicate with the above opening.
In some embodiments, the anti-impact layer may include transparent PC and astigmatism powder, and thus brightness variations may be improved, which should however not be construed as a limitation in the disclosure.
It should be noted that the step of forming the at least one opening OP as provided in the above embodiment is before the step of forming the sputtering layer 120, and the ornament unit 100 is formed before the light-transmitting plastic member is disposed on the ornament unit 100; however, a sequence of forming the opening OP of the light-transmitting element 110, the sputtering layer 120, and the light-transmitting plastic member is not limited in the disclosure.
In some embodiments, the step of forming the at least one opening OP may be after the step of forming the sputtering layer 120, and the light-transmitting plastic member may be provided before the ornament unit 100 is formed on the light-transmitting plastic member, as long as the at least one opening OP running through at least part of the light-transmitting element 110 is formed.

According to actual requirements, the fastener may be a screw, a rivet, a bolt, or the like. The light-emitting member is fixed to the light-transmitting plastic member by means of the fastener, which increases a connection strength between the light-emitting member 140 and the light-transmitting plastic member 130 and prevents the light-emitting member 140 from falling from the light-transmitting plastic member 130.
In yet another embodiment, the light-transmitting plastic member 130 may be coated on an outer side of the light-emitting member 140 by injection molding.
