Abstract：[Objective]In order to further improve the production efficiency of rice seedling assembly line, this study carried out the design and experiment of high-speed automatic stacking device for rice seedling. [Methods]The device consists of a rack, a seedling tray conveying mechanism, a stacking mechanism, and a control system. The device is controlled by a 200 Smart PLC as the core, and the positioning of the seedling tray is achieved through photoelectric sensors. The main and auxiliary conveyor belts are used to realize the start stop and variable speed conveying of the seedling tray, and the automatic stacking of the seedling tray is completed by combining the lifting and lowering of the electric cylinder. Based on the productivity of a 2 000 tray·h-1 rice seedling production line, the value ranges of the main conveyor belt speed, auxiliary conveyor belt speed, and electric cylinder lifting speed were first determined through a single factor experiment. Then, a three factor three-level orthogonal experiment was conducted with the stacking success rate as the experimental indicator to determine the influence of the three factors on the stacking success rate in descending order: auxiliary conveyor belt speed, electric cylinder lifting speed, and main conveyor belt speed; Finally, the experimental results were analyzed for variance using Design Expert 13 software, and a mathematical regression model was established to evaluate the indicators and various factors. Combining response surface analysis to obtain data. [Results]The optimal homework combination is: The main conveyor belt speed is 0.438 m·s-1, the auxiliary conveyor belt speed is 0.607 m·s-1, and the electric cylinder lifting speed is 0.170 m·s~-1, with a corresponding stacking success rate of 93.185%. [Conclusion]The success rate of stacking in the verification experiment was 91.27%, and the error between the experimental results and the theoretical prediction value was less than 5%, proving that the automatic stacking device has good stacking performance and meets the requirements of high-speed rice seedling production line operation.
