Description

Technical Field

[0002] With the continuous development and advancement of industrial technology, the demand for processing diverse types and categories of workpieces is increasing daily. Traditional processing and conveying devices are typically designed for single-type workpieces and cannot meet the processing needs of diverse workpieces. While some flexible conveying devices can adapt to the conveying of different types of workpieces to a certain extent, their complex structures and control systems make them prone to failure, and their long adjustment times prevent them from meeting the requirements for rapid workpiece changeover. Therefore, developing a flexible processing and conveying device and method for diverse types and categories of workpieces is of great significance for improving production efficiency and reducing production costs.

[0003] Chinese Patent Publication No. CN115367446A discloses an assembly line based on a main conveyor line lateral movement operation station. This production line achieves the purpose of conveying workpieces through a single conveyor line, which has strong practicality. However, the conveyor line in this patent has low conveying efficiency, making it difficult to implement process splitting on the same main conveyor line. Furthermore, this patent can only realize material conveying and handling; its conveyor line does not have the function of flexible workpiece conveying. Chinese Patent Publication No. CN212122058U discloses a partitioned multifunctional solar cell laser processing equipment, which can reduce the frequent acceleration and deceleration operations of the galvanometer, improve equipment processing efficiency, and reduce energy consumption and investment costs. However, this patented equipment cannot process multiple models and types of workpieces simultaneously. In addition, this patent cannot realize the handling of processed workpieces, resulting in product transportation stagnation during processing and some waste of production capacity.

[0004] In current industrial production, automated conveyor lines have become an indispensable part; however, existing machine tool processing conveyor lines are difficult to meet the requirements of simultaneously clamping and conveying different types and models of workpieces. Therefore, in the fields of machine tool accompanying fixture conveying and product processing, there is an urgent need for a device and conveying method that can handle the flexible processing and conveying of multiple types and categories of workpieces.
