我国是果品生产大国,苹果、梨、桃等栽培面积均居世界首位,但是我国果园机械化程度不高,特别是在作业量占比达40%的采摘环节。目前水果采摘基本采用人工采摘,其工作量十分繁重且效率低下,急需一种采摘机器人来替代或协助人们的采摘工作。目前部分高校及企业针对采摘环节研发了一系列采摘机器人,但其存在诸如无避障或避障能力差、体积庞大、效率低、成本高、难以实现无损摘取等问题。对于末端执行装置则通常有两种方式:一是抓紧后将果实从枝干拽落,拽落式分离较困难且拽落时容易把果实同果梗分离,造成果实果梗分离处的果肉暴露在外影响果实储藏时间;二是通过剪切装置将果梗与果枝分离,剪切式果梗剪切处较锋利,大量果实混在一起时容易划破彼此表面影响外观及储藏时间;这两种方式各有其缺陷和不足,难以在(无人)机械化采摘中得到有效应用。my country is a major producer of fruit products. The cultivation area of apples, pears, and peaches ranks first in the world. However, the degree of mechanization of orchards in my country is not high, especially in the picking link where the workload accounts for 40%. At present, fruit picking is basically done manually, and its workload is very heavy and inefficient. There is an urgent need for a picking robot to replace or assist people in picking. At present, some universities and enterprises have developed a series of picking robots for the picking process, but they have problems such as no obstacle avoidance or poor obstacle avoidance ability, large size, low efficiency, high cost, and difficulty in non-destructive picking. For the end effector, there are usually two ways: one is to pull the fruit from the branch after grasping it tightly. The fruit storage time is affected externally; the second is to separate the fruit stem from the fruit branch by the shearing device. The shearing fruit stem is sharper at the cutting point, and when a large number of fruits are mixed together, it is easy to scratch the surface of each other and affect the appearance and storage time; these two methods Each has its own shortcomings and deficiencies, and it is difficult to be effectively applied in (unmanned) mechanized picking.

At this time, the second motor 21 is activated to control the sliding rod 3 to move outward along the sliding rail 25. When the 41 is far away from the second fixed seat 26, the finger grips 41 move closer to each other under the action of the connecting rod 42, so that the gripper 4 can grasp the fruit. At this time, the first motor 11 is activated. , the first motor 11 controls the rotation of the rotating rod 2, and the rotating rod 2 drives the gripper 4 to rotate, thereby realizing the separation of the fruit and the stalk. In this embodiment, the stalk and the branch are separated by rotation, which can Avoiding the separation of the fruit from the stalk and causing the pulp of the fruit to be exposed, the fruit can be picked without damage, and the storage time of the fruit can be improved. In addition, the overall volume of the gripper 4 in this embodiment is small, which is conducive to going deep into the fruit tree for picking, and the entire picking process. There is no need to use sharp objects such as blades, so even if a large number of fruits are mixed together, this embodiment can avoid damage to other fruits, and improve the integrity and storage time of fruits after picking.
