AI Technical Summary
Existing chili-picking robots are unstable when gripping chili fruits of different sizes, which can easily cause damage or detachment of the fruits. Furthermore, they have low picking efficiency and fail to protect the chili plants from damage.
A chili harvesting robot was designed, which uses a temporary fixing claw and a cutting component driven by the same drive motor. Combined with a multi-station gripper, the robot continuously grips and cuts the chili stems through an eccentric wheel mechanism. The multi-station gripper adapts to different fruit thicknesses, improving harvesting stability and efficiency.
This method enables stable cutting of chili stems and simultaneous clamping of multiple fruits, improving harvesting success rate and efficiency while protecting the integrity of chili fruits and plants.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of picking hot pepper, especially to a hot pepper picking manipulator. BACKGROUND
[0002] China is a big country of hot pepper production and export, and hot pepper is an important economic pillar crop. The fruit stem of hot pepper is relatively thick and strong, and the fruit part of the mature fruit is drooping. The fruit is long and finger-shaped, with a tapered and often curved top end. The mature hot pepper stem and the hot pepper fruit are easily separated and fallen off. When picking hot pepper, a sharp scissors is needed to cut the hot pepper stem so as to avoid the separation and falling off of the hot pepper stem and the hot pepper fruit. If the hot pepper stem and the hot pepper fruit are separated, it may lead to the exposure of the fruit and the wound of the hot pepper stem to the environment during the later storage and transportation process, which is easy to cause infection and corruption and difficult to store and transport. During the picking operation, the mature hot pepper fruit is in the highest water content stage, the flesh is full, and the peel is easy to be crushed and damaged. The workers should also pay attention to handle the hot pepper gently to avoid pulling or squeezing the fruit to prevent damage.
[0003] At the same time, the workers need to avoid directly pulling the hot pepper fruit as much as possible during the picking process. In addition to the possible separation of the fruit and the hot pepper stem, it is also easy to cause the breakage or damage of the main branch of the hot pepper plant, which further affects the normal growth and development of the immature fruit of the hot pepper plant.
[0004] Therefore, during the mechanical picking, how to protect the hot pepper fruit and the hot pepper plant from being damaged is a key technical problem. In the prior art, for example, a hot pepper picking manipulator based on visual recognition and its end executing mechanism disclosed in Chinese patent publication No. CN116276976A discloses a hot pepper picking manipulator. The root stem cutting assembly is used to cut the hot pepper stem, and the soft clamping jaw is used to clamp the fruit of the hot pepper. During the picking operation, the first electric cylinder pushes the second rotating frame to rotate, the arc-shaped soft pad of the soft clamping jaw clamps the hot pepper, the second electric cylinder pushes the root stem cutting assembly to rotate, the blade of the root stem cutting assembly cuts the hot pepper root stem, and the clamping force and the opening degree of the soft clamping jaw are related to the stroke of the electric cylinder. The fixed stroke of the electric cylinder can only provide the opening and closing degree of a kind of soft clamping jaw. The hot pepper fruit has different thicknesses. When clamping the hot pepper fruit with too small thickness, it is easy to clamp unstably, and the fruit is easy to fall off from the clamping jaw during the transportation process. When clamping the hot pepper fruit with too large thickness, it is easy to clamp too tightly and damage the fruit. Moreover, the mechanical arm can only pick one hot pepper at a time, and it is necessary to continuously put the picked hot pepper into the storage box, which is slow in picking speed.
