With the development of the automobile industry, consumers' requirements for the comfort and aesthetics of automobile interiors are constantly increasing, which prompts automobile manufacturers to continuously improve production processes and enhance product quality.

[0003] In the composite pressing process of the automobile roof, the common method is to complete the laying, heating, cutting and pressing of the substrate by manual operation or simple automated equipment.

The substrate feeding assembly 7 places the glue-coated substrate on the fabric, and the hydraulic cylinder 43 drives the upper punch 4 to press the substrate and the fabric downward. After the pressing is completed, the fabric feeding assembly 8 absorbs the finished product, takes it out and transports it to the unloading place.

[0046] The implementation principle of a composite pressing and forming device for a car roof in an embodiment of the present application is as follows: the design of the substrate supporting platform 12 between the substrate unwinding roller 2 and the substrate heating device 11 ensures the stable placement of the substrate before heating and avoids deformation or damage of the substrate during transportation; the design of the press seat 6 and the cutter 61 thereon can accurately cut the substrate before it enters the heating device, ensuring the accuracy of the substrate size and improving the quality of subsequent processing; the design of the substrate feeding assembly 7 enables the substrate to move smoothly along a predetermined path, ensuring the accurate positioning of the substrate during the heating and pressing process and improving production efficiency and product quality.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
