[0003] In the current cardboard processing process, the cardboard is neatly stacked through a stacking device. This step is crucial for subsequent processing and transportation. The stacking device is usually placed at the end of the conveyor belt to ensure that the cardboard can smoothly slide off the conveyor belt and accumulate on the device. As the cardboard continuously accumulates on the stacking device, when the stacking quantity reaches the requirement, under the operation of the robotic arm, the uneven edges of the cardboard are carefully aligned. This step facilitates subsequent packing and transportation work. After the alignment process, the stacked cardboard is firmly clamped by the robotic arm and transferred to the packing device. This automated process simplifies the steps of cardboard processing, improves work efficiency, and reduces the difficulty and cost of manual operation.
