Description

Technical Field

[0001] This utility model relates to the field of mobile phone glass cover technology, and in particular to a coating device. Background Technology

[0002] With the rise of foldable screen phones and similar smart terminals, the demand for double-sided lamination of mobile phone glass covers is increasing. As a crucial component of smart terminals, mobile phone glass covers undergo complex manufacturing processes, including glass cutting, contour grinding, polishing, hardening, ultrasonic cleaning, vacuum coating, and screen printing. To ensure the safety and integrity of the product during production, processing, transportation, and storage, surface lamination is of paramount importance.

[0003] However, existing lamination processes are inefficient when performing double-sided lamination on mobile phone glass covers. Traditional lamination methods often require separate lamination operations on both sides, which is not only time-consuming but also makes it difficult to guarantee the consistency and quality of double-sided lamination. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, this utility model provides a film coating device.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] The present invention provides a film coating device, comprising:

[0007] A coating mechanism includes a first film inlet shaft, a second film inlet shaft, a guide shaft, and a coating plate. The upper end of the first film inlet shaft is higher than the coating plate, the lower end of the first film inlet shaft is higher than the second film inlet shaft, and the lower end of the guide shaft is not lower than the coating plate. A first film enters the coating plate sequentially through the upper end of the first film inlet shaft and the upper end of the guide shaft, and a second film enters the coating plate sequentially through the lower end of the second film inlet shaft and the lower end of the guide shaft.

[0008] The conveying mechanism includes a first conveying section and a second conveying section, which are respectively disposed at both ends of the film-coated plate. The conveying direction of the conveying mechanism is from the first conveying section toward the second conveying section.

[0009] The film feeding direction of the coating mechanism is perpendicular to the conveying direction of the conveying mechanism.

[0010] In one possible implementation of this application, the coating mechanism further includes a synchronous conveyor, which is connected to the first film-feeding shaft and the second film-feeding shaft respectively.

[0011] In one possible implementation of this application, the coating mechanism further includes a slide rail, the guide shaft is disposed on the slide rail, and the extending direction of the slide rail is perpendicular to the film feeding direction of the coating mechanism.

[0012] In one possible implementation of this application, the conveying mechanism further includes a guide plate disposed on the side of the second conveying section near the guide shaft.

[0013] In one possible implementation of this application, the conveying mechanism further includes a first detection element, which is disposed above the second conveying unit.

[0014] In one possible implementation of this application, the conveying mechanism further includes a second detection element disposed on the plate surface of the second conveying section.

[0015] In one possible implementation of this application, the coating mechanism further includes a third detection element, which is disposed above the coating plate.

[0016] Compared with existing technologies, the coating device of this utility model, with its coordinated arrangement of a first film-feeding shaft, a second film-feeding shaft, a guide shaft, and a coating plate, allows the first and second films to smoothly enter the coating plate from both above and below, respectively, completing the double-sided coating of the mobile phone glass cover. This not only improves the efficiency of coating but also ensures the consistency and quality of double-sided coating. The first and second conveying sections are respectively located at both ends of the coating plate, with the conveying direction from the first conveying section to the second conveying section, perpendicular to the film-feeding direction of the coating mechanism. This perpendicular arrangement ensures the stability of the mobile phone glass cover during the coating process, avoiding offset or misalignment problems caused by inconsistent conveying directions.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0025] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0026] This utility model provides a laminating device. The coordinated arrangement of the first and second film-feeding shafts, guide shaft, and laminating plate in the laminating mechanism allows the first and second films to smoothly enter the laminating plate from both above and below, respectively, completing double-sided lamination of a mobile phone glass cover. This not only improves lamination efficiency but also ensures consistency and quality of double-sided lamination. The first and second conveying sections are respectively located at both ends of the laminating plate, with the conveying direction from the first conveying section to the second conveying section, perpendicular to the film-feeding direction of the laminating mechanism. This perpendicular arrangement ensures the stability of the mobile phone glass cover during the lamination process, avoiding offset or misalignment problems caused by inconsistent conveying directions. Example

[0027] This utility model embodiment provides a film coating device, such as Figure 1 and Figure 2 As shown, the system includes a laminating mechanism 10, which comprises a first film inlet shaft 110, a second film inlet shaft 120, a guide shaft 130, and a laminating plate 140. The upper end of the first film inlet shaft 110 is higher than the laminating plate 140, and the lower end of the first film inlet shaft 110 is higher than the second film inlet shaft 120. The lower end of the guide shaft 130 is not lower than the laminating plate 140. A first film enters the laminating plate 140 sequentially through the upper end of the first film inlet shaft 110 and the upper end of the guide shaft 130. A second film... The film enters the coating plate 140 sequentially through the lower end of the second film inlet shaft 120 and the lower end of the guide shaft 130; the conveying mechanism 20 includes a first conveying section 210 and a second conveying section 220, which are respectively located at both ends of the coating plate 140, and the conveying direction of the conveying mechanism 20 is from the first conveying section 210 toward the second conveying section 220; the film inlet direction of the coating mechanism 10 is perpendicular to the conveying direction of the conveying mechanism 20.

[0028] More specifically, the laminating mechanism 10 also includes a synchronous conveyor 150, which is connected to both the first film feed shaft 110 and the second film feed shaft 120. The synchronous conveyor 150 controls the film feed speed of the first film feed shaft 110 and the second film feed shaft 120, ensuring that their feed speeds are identical. This component, the synchronous conveyor 150, is tightly connected to both the first and second film feed shafts 110 and 120. The function of the synchronous conveyor 150 is to precisely control the film feed speed of the first and second film feed shafts 110 and 120, ensuring that they remain consistent. The importance of this design is self-evident, as the consistency of the film feed speed directly affects the quality and consistency of double-sided lamination. If the film feed speeds on both sides are different, it may cause problems such as stretching, wrinkling, or misalignment of the film during the lamination process, seriously affecting the appearance and performance of the product.

[0029] More specifically, the coating mechanism 10 also includes a slide rail 160, with a guide shaft 130 mounted on the slide rail 160. The extension direction of the slide rail 160 is perpendicular to the film feeding direction of the coating mechanism 10. The slide rail 160 can be used to adjust the height of the guide shaft 130. The guide shaft 130 is mounted on the slide rail 160, and the extension direction of the slide rail 160 is perpendicular to the film feeding direction of the coating mechanism 10. This allows the height of the guide shaft 130 to be flexibly adjusted according to actual needs, thus adapting to mobile phone glass covers of different specifications and thicknesses. By adjusting the height of the guide shaft 130, it can be ensured that the film adheres tightly to the glass cover during the coating process, avoiding air bubbles or gaps, and further improving the coating effect.

[0030] More specifically, the conveying mechanism 20 may also include a guide plate 230, which is located on the side of the second conveying section 220 near the guide shaft 130. The guide plate 230 is used to guide the coated products. Guiding the coated products ensures that they are accurately conveyed along a predetermined path, avoiding problems such as product deviation or falling during conveying. This further improves the stability and reliability of the conveying mechanism 20, ensuring smooth production processes.

[0031] Specifically, the conveying mechanism 20 may further include a first detection element 240, which is positioned above the second conveying section 220. The first detection element 240 can be used to detect whether the upper part of the glass product has been coated. More specifically, the conveying mechanism 20 may also include a second detection element 250, which is positioned on the plate surface of the second conveying section 220. The second detection element 250 can be used to detect whether the lower part of the glass product has been coated. Thus, the first detection element 240, positioned above the second conveying section 220, detects whether the upper part of the glass product has been coated. This ensures that only products with complete upper coating can continue conveying, avoiding product quality problems caused by incomplete upper coating. The second detection element 250, positioned on the plate surface of the second conveying section 220, detects whether the lower part of the glass product has been coated. Similarly, this also ensures that only products with complete lower coating can proceed to the next process, further improving product quality and reliability.

[0032] More specifically, the coating mechanism 10 may also include a third detection element 170, which is positioned above the coating plate 140. The third detection element 170 can be used to detect whether there is a glass product on the coating plate 140, thereby controlling whether the coating mechanism 10 inserts the film. Compared with the prior art, the coating device provided in this embodiment of the present invention, with the cooperative arrangement of the first film-infeeding shaft 110, the second film-infeeding shaft 120, the guide shaft 130, and the coating plate 140 in the coating mechanism 10, allows the first film and the second film to smoothly enter the coating plate 140 from the upper and lower directions respectively, completing the double-sided coating of the mobile phone glass cover. This not only improves the efficiency of coating but also ensures the consistency and quality of double-sided coating. The first conveying part 210 and the second conveying part 220 are respectively located at both ends of the coating plate 140, with the conveying direction from the first conveying part 210 toward the second conveying part 220, perpendicular to the film-infeeding direction of the coating mechanism 10. This vertical arrangement ensures the stability of the phone's glass cover during the lamination process, avoiding offset or misalignment issues caused by inconsistent transport directions.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
