[0002] In the field of small parts assembly, especially for automatic assembly that requires high precision and high efficiency, traditional assembly methods often rely on manual operation or simple mechanical assembly lines. These methods have some significant limitations. For example, manual operation is easily affected by human factors, resulting in unstable assembly accuracy; while traditional mechanical assembly lines often lack sufficient flexibility and real-time adjustment capabilities, making it difficult to cope with complex assembly tasks and changing production needs.

[0003] With the development of automation technology, some advanced automatic assembly systems have emerged. These systems try to solve the bottlenecks of existing assembly technology by introducing automated robots, visual recognition technology and real-time control systems. For example, some automatic assembly systems in the existing technology can use machine vision to detect the position and orientation of parts, thereby achieving precise control of parts during the assembly process. However, these systems still have some problems, especially in terms of position adjustment during part transportation.
