摘　　要：针对现有固化设备固化速率缓慢、自主选择固化所需的紫外LED性能差的问题,提出了一种适用于紫外光固化的LED光源装置。该装置利用不同波长的紫外LED组成阵列结构,实现对油墨固化所需的辐射能量,也能适用于不同的油墨。使用实验设计手法改变LED光照的工作距离、紫外LED阵列方式以及设备运行速度进行实验,实验结果显示,在相同的实验条件下,工作距离、紫外LED阵列方式以及传送带运行速度的改变均导致固化速率发生改变。新的固化装置固化效率、灵活性都优于传统的紫外LED固化设备。Due to the slow curing rate of current curing equipment and poor performance of UV LED required by self-selection for curing, an LED light source device suitable for UV curing is proposed. The device uses UV LED of different wavelengths to form an array structure, realizing the radiation energy required for ink curing, and it can also be applied to different curing agents. The experimental design method is used to change the working distance of LED lights, the array way of UV LED and the running speed of equipment to carry out experiments. Experimental results show that under the same experimental conditions, the changes in working distance, the array way of UV LED and the operating speed of conveyor belt will lead to changes in curing rate. The new curing device is more efficient and flexible than the traditional UV LED curing equipment.
