Description

Technical Field

[0001] The present application relates to the technical field of die-cutting machine equipment, and in particular to an automatic loading and unloading system for a die-cutting machine. Background Art

[0002] Die-cutting machines, key equipment in the printing and packaging industry, are widely used in the forming and processing of various cartons, labels, and other products. Traditional die-cutting processes rely on manual loading and unloading, which is not only inefficient but also prone to deviations during frequent operations, resulting in low product qualification rates and increased production costs. With the development of automation technology, automating the loading and unloading of die-cutting machines has become an effective way to improve work efficiency and reduce labor costs.

[0003] Currently, in the relevant technical field, common solutions for automating the loading and unloading of die-cutting machines include robotic loading and unloading systems and pneumatic suction loading and unloading systems. Robotic loading and unloading systems utilize a mechanical arm structure in conjunction with a corresponding drive device to grasp and release materials. Pneumatic suction loading and unloading systems utilize vacuum suction cups to hold printed products for handling. While these solutions improve work efficiency to a certain extent, the efficiency gains in actual applications remain limited.

[0004] In both of these solutions, whether robotic or pneumatic, the loading and unloading process relies on complex control systems and multi-degree-of-freedom mechanical structures. This leads to high equipment costs and complex maintenance, making efficient and accurate loading and unloading of die-cut materials impossible. Furthermore, insufficient positioning accuracy during the loading and unloading process compromises the quality of the final product. Utility Model Content
