[0038] Wherein, the unwinding roller 1 is used to unwind the basis layer 9 composed of several layers of self-adhesive film and metal foil layer, in the embodiment, self-adhesive film is stacked three layers, which are first self-adhesive film, second self-adhesive film and third self-adhesive film, and the metal foil layer is compounded on the first self-adhesive film, so as to form the basis layer 9, which is sent to the subsequent process, specifically, the peel strength of the glue layer, third self-adhesive film, second self-adhesive film and first self-adhesive film decreases in turn to meet the peeling and waste removal order.

[0039] At least one guide roller 2 is arranged between the unwinding roller 1 and the glue coating device 3 for guiding the winding direction of the basis layer 9, and then the glue coating device 3 coats glue on the metal foil layer according to the antenna contour, wherein the antenna contour is the external contour of the antenna pattern to be formed. The glue coating device includes a glue roller, and the pattern size contour of the glue roller is at least 0.05mm smaller than the antenna contour size. Since the glue has fluidity, glue overflow is prone to occur under pressure after coating glue, so the size of the glue coating is set to be slightly smaller than the size of the antenna contour.

[0040] The UV curing device 4 is used to cure the glue layer coated on the metal foil layer, and the waste removal device includes at least two groups of waste removal roller groups 6 arranged on the upper and lower surfaces of the basis layer 9 to remove waste from the upper and lower directions respectively, specifically, the upper waste removal roller group 6 removes waste by winding the first self-adhesive film to complete the first waste removal, and the lower waste removal roller group 6 is offset towards the downstream direction to remove waste by winding the third self-adhesive film to complete the second waste removal.

[0041] The substrate unwinding device 7 is used to unwind the substrate layer on the glue layer, and the upper part of the metal foil layer after two waste removals is compounded with the substrate layer. The substrate layer is compounded while the finished product is wound.

[0042] Specifically, the substrate unwinding device 7 comprises a composite guide roller 701, and substrate unwinding rollers 702 and finished product winding rollers 703 symmetrically arranged on both sides of the composite guide roller 701. The substrate unwinding rollers 702 and the finished product winding rollers 703 are located on the same side of the base layer 9 as the composite guide roller 701.

[0043] The composite guide roller 701 is arranged between the waste removal device and the winding roller 8, and is attached to the glue layer. The substrate unwinding roller 702 is arranged upstream of the composite guide roller 701, and is used to unwind the substrate layer to the composite guide roller 701. The substrate layer unwound from the substrate unwinding roller 702 is wound around the composite guide roller 701 after passing through a guide roller 2. The substrate layer is adhered to the glue layer by the composite guide roller 701. The finished product winding roller 703 is arranged downstream of the composite guide roller 701 and is symmetrically arranged with the substrate unwinding roller 702, and is used to wind the base layer 9 after the composite substrate layer. The finished product formed after the composite substrate layer is compounded by the composite guide roller 701 is wound around the finished product winding roller 703 after passing through a guide roller 2.

[0044] The winding roller 8 at the end is used to provide winding power while synchronously completing the third waste removal. The winding roller 8 is used to wind the waste layer formed by the self-adhesive film remaining after the waste removal device removes the waste.

[0045] In this embodiment, the die cutting device 5 is a high-low knife die cutting device 5 with a coated knife edge. The knife edge of the high-low knife die cutting device is coated with a release coating. When the knife edge of the die cutting device performs die cutting from above the base layer, it effectively prevents the aluminum foil from adhering to the knife tip.

[0046] Specifically, the waste removal roller group 6 comprises a waste removal guide roller 601 attached to the surface of the base layer 9 and a waste removal winding roller 602 for winding the waste layer. The waste removal winding roller 602 is used to wind the waste layer, and the position of the waste removal is positioned by the waste removal guide roller 601 to form a sequence of first waste removal, second waste removal and third waste removal. The guide roller of the third waste removal is located between the composite guide roller 701 and the winding roller 8.

[0047] The glue layer is formed on the metal foil layer by the glue coating device and the UV curing device. The self-adhesive film layer after die cutting is removed by the waste removal roller group located on the upper and lower surfaces. Then the complete substrate layer is compounded. Finally, the last self-adhesive film layer is removed while the winding roller provides winding power, and the entire antenna manufacturing process is completed. The whole process is non-stop production, which is high in production efficiency and environmentally friendly and pollution-free.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
