Description

Technical Field

[0001] The present invention relates to the field of optical film processing, and in particular to a method and system for processing side shading asynchronous nesting of a vehicle-mounted display reflective film. Background Art

[0002] As the display industry develops, automotive displays are gradually following suit. However, there are significant differences in the structure of automotive LCD modules compared to consumer notebooks. The structure of a common laptop module is a plastic frame + reflector + light guide plate + diffuser + prism. The light guide plate structure layer is generally 1-2mm thick, and the optical film is mainly fixed layer by layer through the plastic frame limit slot. However, in car displays, the light guide plate thickness reaches 3-5mm. To prevent side light leakage, the conventional method is to cut the knife line on the four sides of the reflector and maintain a 3-5mm adhesive area. During assembly, the side edges are folded and attached to the side to block side light leakage. However, the existing process for directly cutting the reflective film through the front has significant drawbacks: It cannot precisely tape the side edges, resulting in significant waste of double-sided tape. Full-section cutting lacks a toothed structure, making it difficult to meet the folding requirements for side shading required by in-vehicle displays. The lack of a protective film during processing easily leads to scratches and foreign matter contamination on the reflective film, resulting in low product yields. These limitations of traditional processes directly restrict the high-precision and reliability requirements of in-vehicle display products. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a method and system for processing the side shading asynchronous positioning of a vehicle-mounted display reflective film. The present invention provides a method for processing the side shading asynchronous positioning of a vehicle-mounted display reflective film, comprising the following steps: S1. First process unit processing: S11. Provide a silicone protective film, and apply a blue release film and double-sided tape thereon. S12. In the asynchronous cutting station, the double-sided adhesive backing film is asynchronously cut and removed by the asynchronous cutting mold, while retaining the double-sided adhesive on the blue release film. The asynchronous cutting is used to save double-sided adhesive material; a semi-finished product is obtained; S2. Second process unit processing: S21. Discharge the semi-finished product and remove the double-sided tape frame waste; S22.

Third process unit processing: S31. In the second cutting station, the semi-finished product is cut into shape three, and a tooth line structure for folding is formed on one or more side edges; S32.

The second feeding shaft adopts a large pulling wheel, which rotates clockwise to pull the main material belt adhered to the silicone protective film 1. The pulling distance of the second feeding shaft is greater than the rotation stroke of the first waste collecting shaft, so that there is a distance difference between the first waste collecting shaft and the second feeding shaft, and then cutting is performed.

[0005] Preferably, the first silicone protective film is a 1-3G silicone protective film.

[0006] Preferably, the final product includes upper and lower protective films, a reflective film in the middle, and a double-sided adhesive layer with a toothed structure on the side of the reflective film.

[0027] The vehicle-mounted display reflective film side shading asynchronous nesting processing method is based on the above-mentioned vehicle-mounted display reflective film side shading asynchronous nesting processing system, and the method includes: In the first step, the silicone protective film 1 is used as the base film and is passed through the first laminating shaft 112 and the first feeding shaft 115 in sequence through the first unloading shaft 114. The blue release film is passed through the first laminating shaft 112 and the first laminating shaft 112 in sequence through the second unloading shaft 113. The blue release film is located above the silicone protective film 1. After the blue release film is attached to the silicone protective film 1, it passes through the first laminating shaft 112 and the top of the second feeding shaft 125 in sequence. That is, the blue release film is attached to the silicone protective film 1 through the extrusion of the first laminating shaft 112. It is worth mentioning that the silicone protective film 1 is a 1-3G silicone protective film. The 1-3g silicone protective film is based on PET (polyethylene terephthalate) and is coated with an organic silicone adhesive. The viscosity range is 1-3 grams (g) ‌23. It is a low-viscosity protective film (less than 10g is low-viscosity) and is suitable for temporary protection of easily scratched materials‌. The double-sided tape is fed through the third unloading shaft 123 and attached to the blue release film. The double-sided tape supporting film is removed by the first waste material collecting shaft 124. At the same time, the second feeding shaft 125 drives the main material strip with the silicone protective film 1 attached to it to pass through the asynchronous cutting die 122. The asynchronous cutting die 122 asynchronously cuts and removes the double-sided tape supporting film to obtain the semi-finished product 1. Specifically, the asynchronous cutting method is as follows: a straight-edge knife and an inner frame knife are provided in the asynchronous cutting mold 122, the straight-edge knife cuts to the silicone protective film 1 as a bottom support, the inner frame knife cuts to the blue release film, and the bottom film of the double-sided tape is wrapped around the first waste collecting shaft 124, and the bottom film of the double-sided tape can be discharged by winding the first waste collecting shaft 124, so that the double-sided tape is evenly and asynchronously attached to the blue release film; the asynchronous operation is achieved by the first waste collecting shaft 124 rotating counterclockwise, and the rotation stroke is the asynchronous distance. The second feeding shaft 125 adopts a large pull wheel, and the large pull wheel rotates clockwise to pull the main material belt attached to the silicone protective film 1. The pulling distance of the second feeding shaft 125 is greater than the rotation stroke of the first waste collecting shaft 124, so that there is a distance difference between the first waste collecting shaft 124 and the second feeding shaft 125, and then cutting is performed to achieve the purpose of asynchronous material saving; In the second process, the semi-finished product 1 enters the first laminating and waste discharging station 21, and the waste of the double-sided adhesive outer frame of the semi-finished product 1 is discharged by OPP tape, and the waste of the double-sided adhesive outer frame of the semi-finished product 1 is discharged by PET, and then the semi-finished product 1 is cut into the outer shape of the double-sided adhesive by the first cutting station 22 to obtain the semi-finished product 2; specifically, the third equipment frame 211 is provided with multiple sets of fourth discharge shafts 213 and second waste collection shafts 214, see Figure 3As shown, the OPP tape is discharged through one of the fourth unloading shafts 213, attached to the semi-finished product 1, and adhered to the blue window release film waste produced by the previous process. The OPP tape with the blue window release film waste is then collected by the second waste collection shaft 214. Similarly, the other set of the fourth unloading shaft 213 and the second waste collection shaft 214 remove the waste produced by the double-sided tape cutting through PET. The semi-finished product 2 then enters the second laminating and waste removal station 23, where the cover film waste on the surface of the semi-finished product 2 is removed with OPP tape, and the double-sided tape waste on the surface of the semi-finished product 2 is removed with PET. Then, a reflective film is laminated on the surface of the semi-finished product 2 to obtain the semi-finished product 3. Specifically, the waste removal method is the same as in step 2. In process three, the semi-finished product three enters the second cutting station 31 to cut the shape, that is, the overall shape of the reflective film plus the double-sided tape, and then enters the third laminating and waste discharge station 32 to discharge the waste reflective film of the outer frame of the semi-finished product three. Then, the silicone protective film two is laminated on the reflective film surface of the semi-finished product three, the waste silicone protective film one is peeled off, and the protective film three is laminated. The purpose is to protect the surface of the finished product from being scratched. Finally, it enters the slicing station 33 for slicing. It is worth mentioning that the protective film three uses HD-5003 protective film.

[0028] The purpose of this embodiment is to obtain a final structural product after three processing steps, and to laminate protective films on the upper and lower surfaces, and finally to slice. The product includes upper and lower protective films, namely, silicone protective film 2 and protective film 3, a middle reflective optical film, namely, a reflective film, and double-sided tape on the sides; It is worth mentioning that, in some embodiments, the mold of the second cutting station 31 has tooth line cutting, so that after being processed by the second cutting station 31, the product can be folded along the tooth line when it is used, thereby achieving a side shielding effect.

[0029] The exemplary implementation schemes proposed in the present disclosure are described in detail above with reference to preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the scope of protection of the present disclosure, which is determined by the appended claims.
