In order to solve the micro potato production process, there is a lot of labor demand and affairs from the group culture seedlings to the production of sheds, and an adsorption end-effector that works with five groups of seedlings can be taken at a time. Under the control of the PLC, the adsorption end-effector completed the change in the historical cassette and the acupoints; the vacuum generated by the vacuum generator, so that the nozzle would seed the seedlings; after the adsorption end-effector was moved to the acupoint and cut off the vacuum. The group seedlings were placed in the pocket bore and completed the transplanting process of the group seedlings. The key parameters of the nozzle were analyzed and determined, and the effect of a good nozzle type was selected by simulation analysis and single factor test. In order to clarify the influence of the acupoint diameter d, the spacing adjustment speed v1, the positive pressure p1, and the seedling holding height h and other factors on the transplanting effect, the transplanted success rate was orthogonal test. The results showed that the seedling holding height h had a significant effect on the success rate of transplanted plants, while the hole diameter d, the spacing adjustment speed v1, the blow seed positive pressure p1 had no significant effect; when the hole diameter d was 15mm, the spacing adjustment speed v1 was 50mm/s, blow seedling positive pressure p1 was 1000Pa,seedling clamping height h was 45mm, the transplanted success rate of group culture seedlings was the highest, was 87.98%, and the transplanting effect of the adsorption end-effector was the best, the transplanting efficiency was 2087 plants/hour, which met the design requirements.
