[0002] With the development of modern manufacturing, in response to the dual pressures of rising labor costs and improving production efficiency, the assembly of die-cut products is increasingly turning to the use of automated materials. Automated materials not only significantly reduce the need for manual operation, but also significantly improve the accuracy and consistency of assembly.

[0003] However, in the automated assembly of die-cut products, product design plays a crucial role in material utilization. To facilitate lamination, the gap between automated materials is typically designed to be 3-5 mm. This design does facilitate smooth assembly, but it also presents a problem: when laminating smaller products using a single sheet, the material utilization of the primary material is extremely low, often reaching only 20%-30%.

[0004] To improve material utilization, the industry generally adopts an asynchronous process. This process optimizes the equipment's operating sequence, reducing the spacing between the main materials to 1-2 mm. While this improvement has significantly improved material utilization, raising it to 30-40%, some issues remain. For example, the asynchronous process often produces scrap during the process of reducing spacing, which not only increases production costs but also places an unnecessary burden on the environment.
