Description

Technical Field

[0002] Fully automatic laser cutting line is an automated production line that integrates multiple devices. It usually includes key equipment such as unwinder, leveler, conveyor and laser cutting machine. These equipments realize the process of automatic loading, leveling, conveying and cutting of plates through sequential series connection and collaborative work. The main function of the plate positioning device is to ensure that the plate can be stably and accurately fixed on the cutting table during the laser cutting process.

Although this method has certain flexibility and adaptability, manual adjustment requires workers to spend more time and energy to accurately adjust the position of the clamp, especially when dealing with large plates or needing to change plates frequently. This fixing method will significantly reduce production efficiency, and manual operation is difficult to ensure that the accuracy of each adjustment is completely consistent, which may result in the remaining size of the plate after cutting being very different, which not only wastes materials, but also increases the difficulty and cost of subsequent processing (such as deburring, trimming, etc.).
