Description

One kind separates the comb-type automatic picking end effector of move toward one another Kiwi berry
Technical field
The present invention relates to agricultural robot automation equipment field, in particular it relates to a kind of separate comb-type move toward one another The automatic picking end effector of Kiwi berry.
Background technology
China is the maximum country of world Kiwifruit Culture area, but, domestic Kiwi berry no matter in export price or In export volume, New Zealand and other exported countrys are all slightly poorer than, directly result in heavy economic losses of the country in agricultural product export trade, Reason is exactly that the automatic picked technology of China's Kiwi berry falls behind, mainly by the harvesting operation for manually carrying out Kiwi berry, and macaque Peach plucking cycle concentrates very much again, and labour intensity is big, expends substantial amounts of labour, time, inefficiency.At present both at home and abroad for agriculture The key of the research of industry picking robot is still efficiency, and the harvesting pattern of kiwifruit fruit determines picking robot end The structure type and operation principle of actuator, while also determining operating efficiency.The A of CN 103448061 that Chinese patent is announced " a kind of kiwifruit fruit picking end effector " uses profiling finger grip fruit, rotates the pattern plucked, single fruit used time 22s, efficiency is too low.A kind of harvesting pattern of move toward one another is proposed after mechanism test was done in laboratory, effect can be greatly improved Rate.Therefore it is badly in need of a kind of separation automatic picking end effector of comb-type move toward one another Kiwi berry to solve this technical barrier, But do not have such device in the market.
The content of the invention
This patent provides a kind of separation comb-type automatic picking end effector of move toward one another Kiwi berry, present invention machinery Simple structure, greatly reduces labour intensity, time saving and energy saving, efficiency high, realizes the separation of fasciation Kiwi berry, and many fruits are once Property pluck, solve Kiwi berry single fruit and pluck the technical barrier wasted time and energy.
The technical scheme adopted by the invention to solve the technical problem is that:
One kind separates the comb-type automatic picking end effector of move toward one another Kiwi berry, is by oscillating cam mechanism, inclines Curved surface rushing board mechanism, linear reciprocation drive mechanism, installing plate, fruit are separated combs molecular, it is characterized in that:Oscillating cam mechanism Including master cam in a row, pressure sensor, adjustment gap, U-shaped support, cam shaft and electric rotating machine, curved surface push pedal is inclined Mechanism includes skew surface push pedal in a row, microsensor and twin shaft cylinder, and linear reciprocation drive mechanism includes L-type support, leads Bar, guide bar support, guide rod base, linear electric motors, nut slider, leading screw and reciprocator's support;The oscillating cam mechanism peace Mounted in linear reciprocation drive mechanism front end, the inclination curved surface rushing board mechanism is arranged on linear reciprocation drive mechanism top, described Linear reciprocation drive mechanism is set on a mounting board, and the installing plate top separates comb connection, the profiling in a row with fruit Cam is arranged on U-shaped support by cam shaft, and is connected with electric rotating machine, and the pressure sensor is arranged in a row imitative Shape cam inner surface, the adjustment gap is arranged between master cam in a row;The skew surface push pedal in a row is arranged on twin shaft Cylinder front end, the twin shaft cylinder is arranged on linear reciprocation drive mechanism top, and the microsensor is arranged in a row tiltedly bent Face push pedal bottom;The L-type support is connected with guide rod, and the guide rod is connected by guide bar support with guide rod base, the guide rod Base is connected with nut slider, and the nut slider and leading screw coordinate, on reciprocator's support, the linear electric motors with Leading screw is connected.
Preferably, the master cam outline in a row is designed to imitative Kiwi berry outer contour shape, and surface adhesion has One layer of 3mm thick soft silica gel material.
It is highly preferred that the skew surface push pedal in a row is designed to inclined imitative Kiwi berry foreign steamer contour curved surface, pressed from both sides with horizontal plane Angle is 75 °~85 ° adjustable, and surface adhesion has the thick soft silica gel materials of one layer of 3mm.
Specifically, the fruit separates the comb in a row that comb is provided with interval 20mm, and front end sets V-shaped.
The beneficial effects of the invention are as follows:
A kind of comb-type automatic picking end effector of move toward one another Kiwi berry that separates of the invention can realize Kiwi berry Many fruits separate and disposable harvesting.First, fruit separates comb and separates fasciation kiwifruit fruit, attitude in a row, straight line Reciprocating drive mechanism drives oscillating cam mechanism and inclines curved surface rushing board mechanism near kiwifruit fruit, when microsensor detection During to signal, electric rotating machine drives 90 ° of master cam clockwise oscillation in a row, while twin shaft cylinder pushes away skew surface push pedal in a row Go out, kiwifruit fruit is slipped in storage case along the outer contour surface of master cam in a row;Secondly, when microsensor does not have When having signal, illustrate that kiwifruit fruit has been plucked successfully, be slipped in storage case by master cam foreign steamer contour curved surface in a row, Wherein pressure sensor is provided with threshold value, once pressure exceedes the upper limit, mechanism's stop motion prevents the surface damage of Kiwi berry. Mechanical structure of the present invention is simple, greatly reduces labour intensity, time saving and energy saving, efficiency high, realize really separate more than Kiwi berry and It is disposable to pluck, solve Kiwi berry and pluck the problem for wasting time and energy.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
