[0030] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Embodiment 1

[0032] This embodiment provides a tea-picking robot, mainly but not limited to the picking of high-quality tea in hilly and mountainous areas, such as Figures 1 to 4 As shown, it includes a main body box 10, a traveling mechanism 20 and two tea-picking mechanisms; a controller and a tea collection device are arranged in the main body box 10; the tea collection device includes a tea collection box 40 and a vacuum pump 41; the suction port of the vacuum pump 41 is communicated with the inside of the tea collection box 40; the traveling mechanism 20 is arranged below the main body box 10, and the traveling mechanism 20 is used to drive the main body box 10 to move; the two tea-picking mechanisms are respectively arranged on both sides of the main body box 10 in the traveling direction; the tea-picking mechanism includes a moving mechanism, a visual recognition mechanism, a picking box 30 and at least two picking components; the moving mechanism is arranged on the main body box 10, the picking box 30 is arranged at the output end of the moving mechanism, and the output end of the moving mechanism is used to drive the picking box 30 to change its spatial position; the visual recognition mechanism is used to identify the tea leaves to be picked (the visual recognition mechanism for identifying the tea leaves to be picked is the prior art and will not be elaborated here); each picking component is arranged on the picking box 30, and the picking component includes a flexible telescopic tube 32 (such as a corrugated tube), a picking tube 33, a telescopic device 34 and a picking jaw 35; one end of the flexible telescopic tube 32 can be relatively fixed to the position of the picking box 30, and the opening of this end of the flexible telescopic tube 32 (the opening of the end fixed to the picking box 30) can be communicated with the inside of the tea collection box 40, and the flexible telescopic tube 32 can be telescopic; the other end of the flexible telescopic tube 32 is connected and communicated with one end of the picking tube 33, and each picking tube 33 is located below the picking box 30; the telescopic device 34 is arranged in the picking box 30, and the telescopic end of the telescopic device 34 is provided with a picking jaw 35, and the picking jaw 35 is used to fixedly clamp the cut-off part of the tea leaves to be picked; the telescopic end of the telescopic device 34 passes through the flexible telescopic tube 32 and the picking tube 33, and the telescopic end of the telescopic device 34 is fixedly connected with the picking tube 33, and the picking jaw 35 is located in the end opening of the picking tube 33 (the picking jaw 35 can be arranged in the picking tube 33 and has a certain distance from the end of the picking tube 33 with the end opening, and this distance can be set as needed, such as set according to the length of the cut-off part of the tea leaves to be picked, etc.); the controller is communicatively connected with the traveling mechanism 20, the vacuum pump 41, and the moving mechanism, the visual recognition mechanism, the telescopic device 34 and the picking jaw 35 in each tea-picking mechanism.

[0033] By arranging a picking assembly on each side of the main body box 10, when picking tea leaves, the picking assemblies on both sides can pick the tea leaves on the corresponding tea ridge on one side; and a plurality of picking assemblies are arranged on the picking box 30 on one side, which form a plurality of end effectors on one side. Through the arrangement of the plurality of picking assemblies, the picking of tea leaves at multiple picking points can be realized at one time, so as to achieve high picking efficiency; the visual recognition mechanism is used to recognize information such as the position and shape of the tea leaves to be picked, providing an accurate positioning basis for picking. The controller, according to the information provided by the visual recognition mechanism, controls the moving mechanism to move the position of the picking box 30 so that it is placed above the area of the tea leaves to be picked. The picking assemblies corresponding to the tea leaves to be picked at different height positions in the area directly below the picking box 30 can be independently lifted and lowered under the control of the controller, so as to realize the one-to-one correspondence between the tea leaves to be picked at each position and the picking assemblies. The picking jaw 35 is arranged at the telescopic end of the telescopic device 34, and both are located inside the picking tube 33. In the negative pressure environment inside the picking tube 33, the tea leaves to be picked can enter the picking tube 33 more accurately, so that the picking jaw 35 can fix and clamp them; and under the fixed clamping of the picking jaw 35, by retracting the telescopic end of the telescopic device 34, a "lifting" type picking of the tea leaves to be picked is formed inside the picking tube 33. This method can reduce the interference to the surrounding tea leaves and achieve more accurate picking. The tea leaves picked in this way have complete buds and high tenderness, and are more attractive in appearance. The complete and beautiful tea leaves are often regarded as a symbol of good quality, especially meeting the appearance requirements for high-end tea; the telescopic end of the telescopic device 34 can drive the picking tube 33 and the picking jaw 35 located inside the picking tube 33 to descend together, realizing a more accurate picking operation; after the tea leaves to be picked are picked, they can be adsorbed into the tea leaf collection box 40 under the action of negative pressure for centralized storage; it adopts a relatively simple structure, the overall structure is simpler, the communication connection between the controller and each component is relatively concise, and it does not require complex multi-axis linkage control like a robotic arm, reducing the manufacturing cost.

[0034] Among them, the relevant settings of the main body box 10 are described as follows:

[0035] In the optional solution of this embodiment, preferably, such as Figure 4As shown in the figure, the bottom of the tea collection box 40 is provided with a conical channel pipe 401; an electric control valve 402 is arranged at the small-mouth end of the lower end of the conical channel pipe 401; the electric control valve 402 is communicatively connected with the controller; a drawer-type tea collection box 42 is arranged inside the main body box 10, and the upper opening of the drawer-type tea collection box 42 corresponds to the position of the small-mouth end of the lower end of the conical channel pipe 401; an opening and closing door 12 is arranged on the main body box 10, and the drawer-type tea collection box 42 can be pulled out inside the main body box 10. The conical channel pipe 401 at the bottom of the tea collection box 40 can guide the tea to fall centrally, enabling the tea to converge more smoothly into the collection box below, avoiding uneven accumulation or blockage of the suction space of the tea in the collection box, and improving the collection efficiency; in cooperation with the electric control valve 402 and the drawer-type tea collection box 42, classification collection can be carried out according to different picking batches, tea varieties or quality grades, etc., facilitating subsequent sorting and processing; the drawer-type tea collection box 42 can be pulled out from the main body box 10. This design enables the operator to easily take out the collection box for tea transfer or processing during or after picking, without complex operations or disassembly processes, saving time and labor; the setting of the opening and closing door 12 can maintain a relatively closed environment inside the main body box 10 during tea collection and storage, reducing the influence of external factors such as dust and moisture on the tea, and helping to protect the quality and freshness of the tea.

[0036] Specifically, necessary slide rails 13 can be arranged at the position corresponding to the drawer-type tea collection box 42 inside the main body box 10, and sliding grooves cooperating with the slide rails 13 can be arranged at the bottom of the drawer-type tea collection box 42; and rolling wheels can be arranged at the positions corresponding to the slide rails 13 inside the sliding grooves to improve the smoothness of pulling and reduce wear; and an induction sensor can be arranged inside the drawer-type tea collection box 42, and an alarm is arranged on the main body box 10. When the tea capacity inside the drawer-type tea collection box 42 reaches the threshold, the induction sensor can be triggered to generate an induction signal (the induction sensor here is an existing sensor, and any sensor that can be used to monitor the tea capacity is acceptable), and the controller is communicatively connected with both the induction sensor and the alarm, and a prompt is made through the alarm.

[0037] In an alternative solution of this embodiment, preferably, as Figure 4 shown, a blocking net 403 is arranged on one side of the tea collection box 40 close to the suction port of the vacuum pump 41; the conical channel pipe 401 is located on the side of the blocking net 403 away from the suction port of the vacuum pump 41. The setting of the blocking net 403 can effectively block the tea from entering the suction port of the vacuum pump 41, ensure the normal operation of the vacuum pump 41, and improve the overall reliability and stability of the tea-picking robot.

[0038] Specifically, when the vacuum pump 41 stops working, the tea adsorbed on the blocking net 403 can automatically fall into the conical channel pipe 401 based on gravity, reducing the influence on suction.

[0039] Among them, the relevant settings of the tea picking mechanism are described as follows:

[0040] Specifically, the picking jaw 35 is an existing device, which can be a mini-jaw of the pneumatic fixture type. A ventilation control device for control can be arranged in the picking box 30. The trachea of the ventilation control device sequentially passes through the first shelving tube 31, the flexible telescopic tube 32 and the picking tube 33 and then is connected to the picking jaw 35 located in the picking tube 33.

[0041] In an alternative embodiment of the present embodiment, preferably, as Figures 1 to 3 shown, a plurality of first shelving tubes 31 are fixed in the picking box 30, and the first shelving tubes 31 correspond to the flexible telescopic tubes 32 one by one; one end of the first shelving tube 31 is closed, and the other end opening of the first shelving tube 31 is connected and communicated with the end of the flexible telescopic tube 32 away from the picking tube 33; the telescopic device 34 is fixedly arranged in the first shelving tube 31; a side opening is formed on the side wall of the first shelving tube 31, and the side opening is connected with a branch tube 36, and the branch tube 36 can be communicated with the inside of the tea leaf collection box 40; the telescopic end of the telescopic device 34 passes through the flexible telescopic tube 32 from inside the first shelving tube 31 and is located in the picking tube 33. Fixing the telescopic device 34 in the first shelving tube 31 can provide stable support and protection for the telescopic device 34. The first shelving tube 31 is equivalent to a protective shell, which can prevent the telescopic device 34 from being interfered and damaged by external factors, such as collision, scratching, etc. At the same time, it also helps to reduce the shaking and vibration of the telescopic device 34 during the working process, making its telescopic action more accurate and stable, thereby improving the clamping accuracy of the picking jaw 35 for tea leaves; the setting of the first shelving tube 31 makes full use of the space inside the picking box 30, enabling components such as the telescopic device 34 and the flexible telescopic tube 32 to be reasonably arranged without occupying too much extra space. At the same time, the branch tube 36 connected to the side opening can also skillfully guide the tea leaves into the tea leaf collection box 40, making the structure of the entire picking mechanism more compact and improving the space utilization rate on the premise of ensuring the realization of functions.

[0042] Specifically, the position where the trachea is arranged in the first shelving tube 31 and the partition guiding plate 311 inside the first shelving tube 31 can be set as a sliding and sealing structure in the prior art, so as to ensure the negative pressure environment of the lower cavity 312.

[0043] In an alternative embodiment of the present embodiment, preferably, as Figure 3As shown, the telescopic device 34 is an electric push rod; a partition guiding plate 311 is fixed inside the first shelving pipe 31, and the partition guiding plate 311 is fixed between the outer shell of the electric push rod and the inner wall of the first shelving pipe 31; and the partition guiding plate 311 divides the inner cavity of the first shelving pipe 31 into an upper cavity and a lower cavity 312; the axis of the first shelving pipe 31 is in a vertical posture, and the upper cavity is located above the lower cavity 312; the side opening communicates with the highest position in the lower cavity 312. The partition guiding plate 311 divides the inner cavity of the first shelving pipe 31 into an upper cavity and a lower cavity 312, and the side opening communicates with the highest position in the lower cavity 312. When the tea leaves enter the first shelving pipe 31 through the flexible telescopic pipe 32, they will enter the lower cavity 312. The partition guiding plate 311 can form a guiding flow path constraint for the tea leaves, making it enter the tea collection box 40 more smoothly.

[0044] Specifically, the fixed connection method between the telescopic end of the telescopic device 34 and the picking pipe 33 can be any existing one, including but not limited to the method of using an annular connection bracket 37 and a tightening member 38 mentioned below.

[0045] In an alternative solution of this embodiment, preferably, as Figure 3 shown, at least one annular connection bracket 37 (multiple can be set according to needs, such as two or three, etc.) is detachably fixed on the telescopic end of the telescopic device 34, and the annular connection bracket 37 is located inside the picking pipe 33; the side wall of the picking pipe 33 has elasticity (such as an existing transparent steel wire reinforced pipe), and a tightening member 38 (such as a zip tie, a stainless steel clamp, etc.) is sleeved outside the picking pipe 33 corresponding to the position of the annular connection bracket 37, and the tightening member 38 can make the inner wall of the picking pipe 33 fixedly fit with the outer side wall of the annular connection bracket 37; a through-flow hole for the tea leaves to pass through is provided on the annular connection bracket 37. The telescopic end of the telescopic device 34 is connected to the picking pipe 33 through the detachable annular connection bracket 37, and the tightening member 38 makes the inner wall of the picking pipe 33 closely fit with the outer side wall of the annular connection bracket 37. This connection method ensures the stable connection between the telescopic device 34 and the picking pipe 33. When the telescopic device 34 drives the picking jaw 35 to perform the picking action, it can effectively prevent the picking pipe 33 from shaking or shifting, ensuring the accuracy of the picking action; when the picking pipe 33 is worn, damaged or needs to be cleaned, it can be replaced or processed separately without replacing the entire telescopic device 34 or the picking assembly, thereby reducing the maintenance cost and downtime and improving the use efficiency of the tea picking robot; the through-flow hole provided on the annular connection bracket 37 provides a smooth flow channel for the picked tea leaves; the side wall of the picking pipe 33 has elasticity, and the tightening member 38 can be adjusted according to the shape and size of the annular connection bracket 37 to make the picking pipe 33 closely fit on the annular connection bracket 37.

[0046] In an alternative solution of this embodiment, preferably, asFigure 1 and Figure 2 As shown in Figure 2 , the moving mechanism includes a first linear module 20 and a second linear module 21. The first linear module 20 is fixedly arranged at the upper end of the main body box 10, and the axis of the ball screw 24 of the first linear module 20 is parallel to the vertical direction. The second linear module 21 is fixedly arranged on the sliding seat 25 of the first linear module 20. The axis of the ball screw 24 of the second linear module 21 is perpendicular to both the vertical direction and the traveling direction of the main body box 10. The picking box 30 can be arranged on the sliding seat 25 of the second linear module 21. The axis of the ball screw 24 of the first linear module 20 being parallel to the vertical direction enables the picking box 30 to make precise position adjustments in the vertical direction to adapt to tea trees of different heights. The axis of the ball screw 24 of the second linear module 21 being perpendicular to both the vertical direction and the traveling direction of the main body box 10, and the picking box 30 being arranged on the sliding seat 25 of the second linear module 21 means that the picking box 30 can move in the horizontal transverse direction, thereby performing reciprocating picking in the horizontal transverse direction.

[0047] In an alternative embodiment of the present embodiment, preferably, as Figure 1 and Figure 2 shown in Figure 2 , the moving mechanism further includes a third linear module 22. The third linear module 22 is fixedly arranged on the sliding seat 25 of the second linear module 21. The axis of the ball screw 24 of the third linear module 22 is parallel to the vertical direction. A connecting and fixing frame 23 is fixed on the sliding seat 25 of the third linear module 22, and the connecting and fixing frame 23 is fixedly connected to the picking box 30. Assigning the height adjustment function of the picking box 30 to the third linear module 22 can make the motion control more flexible and precise. Different linear modules can respectively undertake motion tasks in different directions and with different precisions, reducing the load and control complexity of a single module. For example, the first linear module 20 is responsible for large-range vertical height adjustment, and the third linear module 22 is responsible for fine height adjustment. In this way, each module can be optimized in design and control according to actual requirements, improving the performance and reliability of the entire moving mechanism and extending the service life of the equipment.

[0048] Specifically, the cooperation between the third linear module 22 and the first linear module 20 can achieve a larger range of adjustment in the height direction, and the overall height can be reduced.

[0049] Among them, the relevant settings of the traveling mechanism 20 are described as follows:
