[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] like Figure 1 As shown, the present invention provides an automatic loading change UAV airport, comprising a loading cabinet 10, and at least two groups of loading flat plates 11 arranged on the loading cabinet 10 for carrying items, and the loading flat plates 11 slide along the vertical direction of the loading cabinet 10 to form a loading height adjustment structure;

[0046] The picking platform 20 is arranged at the opening of the loading cabinet 10. A guide column 21 is arranged on one side of the picking platform 20. The picking platform 20 is movable up and down along the vertical direction of the guide column 21 and is aligned with the loading plate 11 to form a docking structure. The picking platform 20 is vertically telescopic along its movement direction and is movably abutted with the loading plate 11 to form a telescopic bearing structure.

[0047] The positioning loading platform 30 is horizontally arranged at the top of the loading cabinet 10. A docking plate 31 is provided at the center of the positioning loading platform 30. The docking plate 31 is perpendicular to the movement direction of the loading flat plate 11. The loading flat plate 11 is movably abutted against the docking plate 31 after being translated along the movement direction, so that the items are transferred to the docking plate 31 to form a positioning feeding structure.

[0048] The present invention adopts a three-dimensional loading form to form a drone loading and replacement airport with an item scheduling structure, which can achieve the purpose of automatic replenishment and loading. It has a storage structure and cooperates with a retrieval platform to move the required items to a fixed position in advance, and automatically delivers the items when the drone returns, thereby achieving the purpose of automatic docking and replacement of loading, reducing loading time and improving delivery efficiency.

[0049] The items in the loading cabinet 10 are moved to the positioning loading platform 30 through the picking platform 20, the drone is positioned with the positioning loading platform 30, and the items on the positioning loading platform 30 are loaded through the gripper configured at the bottom of the carrying drone, completing the work of automatically changing the loading of the drone.

[0050] like Figure 1 and Figure 2 As shown, the loading plate 11 is parallel to the width direction of the opening of the loading cabinet 10 and is provided with at least two groups of active rollers 12 and at least two groups of driven rollers 13. The active rollers 12 and the driven rollers 13 are alternately arranged, and the upper surfaces of the active rollers 12 and the driven rollers 13 are at the same height and higher than the upper surface of the loading plate 11;

[0051] A main shaft rod 121 is provided through the length direction of the active roller 12, and a secondary shaft rod 131 is provided through the length direction of the driven roller 13. Both ends of the secondary shaft rod 131 are connected to the loading plate 11 through bearings.

[0052] A driving motor 14 is provided on one side of the loading plate 11 located at the driving roller 12 , and the output shaft of the driving motor 14 is connected to the main shaft 121 through a pulley 122 . At least two groups of driving rollers 12 are connected to each other through a belt 123 and a pulley 122 .

[0053] The active roller 12 helps to move the items. When storing and placing items, the items can be sent deep into the loading cabinet 10. When retrieving items, the items inside the loading cabinet 10 can be moved to the opening and further transferred to the retrieval platform 20. The gap between the active roller 12 and the driven roller 13 helps to enhance the air circulation around the items, thereby achieving the purpose of ventilation and storage.

[0054] When in use, the main shaft 121 and the active roller 12 are driven to rotate by the driving motor 14, and the belt 123 and the pulley 122 can simultaneously drive at least two groups of active rollers 12 to rotate, which is beneficial to keep at least two groups of active rollers 12 rotating synchronously, and further drive the objects to move by rolling friction. While the objects are moving, the friction drives the driven roller 13 to rotate, thereby better helping the objects to move, and conveniently moving the objects to the deep part of the loading cabinet 10, or removing the objects from the deep part of the loading cabinet 10.

[0055] like Figure 1 As shown, a constant temperature control component 15 is provided on the loading cabinet 10, and the output end of the constant temperature control component 15 is connected to the loading plate 11 through an air supply pipe 16, and the air supply pipe 16 includes a fixed pipe 161 and a telescopic hose 162;

[0056] The constant temperature control component 15 includes a refrigerator 151 , a fan 152 , a temperature controller 153 and a temperature sensor 154 . The refrigerator 151 is connected to the air supply pipe 16 via the fan 152 .

[0057] The constant temperature control component 15 is used to help maintain the temperature in the loading cabinet 10 at a suitable state. The temperature sensor 154 is used to monitor the temperature in the loading cabinet 10, and the signal is transmitted to the temperature controller 153 to control the refrigerator 151 to work, and cooperate with the fan 152 to transmit the cold air to the loading plate 11 through the air supply pipe 16. The cold air is transported to the surrounding of the items through the loading plate 11, which is convenient for storing the items. Especially when the temperature is high, it can prevent the items stored in the loading cabinet 10 from deteriorating due to sunlight.

[0058] The fixed tube 161 is connected to the portion close to the loading plate 11 , and cooperates with the telescopic hose 162 to form a telescopic structure, so that the air supply tube 16 can be telescoped and extended according to the height adjustment of the loading plate 11 .

[0059] like Figure 1 and Figure 5 As shown, an air outlet channel 17 is provided on the lower surface of the loading plate 11, and the air outlet channel 17 is connected to the air supply pipe 16 to form an air supply structure;

[0060] Among them, the air outlet channel 17 includes a four-way pipe 171 connected to the fixed pipe 161, the output end of the four-way pipe 171 is connected to the annular pipe 173 through a straight pipe 172, the center position of the annular pipe 173 is located at the center position of the object loading plate 11, and a special-shaped pipe 174 is arranged on the outer circle of the annular pipe 173, and air outlets 175 are evenly spaced on the straight pipe 172, the annular pipe 173 and the special-shaped pipe 174.

[0061] The constant temperature control component 15 and the loading plate 11 are connected through the air outlet channel 17, which is conducive to the air outlet 175 moving together with the loading plate 11, so that during the height adjustment process of the loading plate 11, the air outlet 175 can always act around the objects, and can avoid as much as possible the possibility of blocking part of the air outlet position when the height of the loading plate 11 is adjusted, thereby helping to maintain the constant temperature effect in the loading cabinet 10.

[0062] The annular tube 173 and the special-shaped tube 174 are connected by the four-way tube 171 and the straight tube 172, so that the air outlet 175 is distributed as evenly as possible at the bottom of the loading plate 11, thereby facilitating the distribution of cold air and making the temperature of each layer of the loading cabinet 10 more uniform, which is beneficial to the storage of items.

[0063] like Figure 1 and Figure 4 As shown, a height adjustment assembly 18 located on the loading cabinet 10 is provided on one side of the loading flat plate 11, and at least two groups of loading flat plates 11 form an independent adjustment structure on the loading cabinet 10 through the height adjustment assembly 18, and a side of the loading flat plate 11 away from the height adjustment assembly 18 is slidably connected to the loading cabinet 10 through a slider;

[0064] Among them, the height adjustment component 18 includes at least two groups of rotating motors 181 and at least two groups of rotating screws 182. The outer wall of the rotating screw 182 is threadedly connected with a sleeve 183, and the sleeve 183 is movably connected to the loading plate 11. The output end of the rotating motor 181 is connected to the rotating screw 182 through a pulley assembly 184.

[0065] The height of the loading platform 11 is adjusted by the height adjustment component 18. Through three sets of independent adjustment, the storage space of each layer of the loading cabinet 10 can be reallocated. The space of each layer can be freely allocated according to different items, thereby achieving the purpose of space optimization.

[0066] The rotating motor 181 drives the rotating screw 182 to rotate, and the shaft sleeve 183 is threadedly connected with the rotating screw 182, further driving the object loading plate 11 to adjust the height on the rotating screw 182;

[0067] By using at least two sets of rotating motors 181 and rotating screws 182 to correspond to the loading plates 11 on each layer respectively, it is convenient to independently control the loading plates 11 on each layer, thereby adjusting the height of the loading plates 11 on each layer, and further better allocating the spatial layout of each layer inside the loading cabinet 10, so as to facilitate adjustment and use according to the actual stored items.

[0068] like Figure 1 , Figure 2 and Figure 3As shown, a negative pressure head 22 is provided on the picking platform 20, the opening direction of the negative pressure head 22 is perpendicular to the movement direction of the picking platform 20, and a power source assembly 23 located on the guide column 21 is provided at one end of the negative pressure head 22;

[0069] The power source assembly 23 includes a negative pressure machine 231 , a control valve 232 and an output hose 233 , and the output end of the negative pressure machine 231 is connected to the negative pressure head 22 via the output hose 233 .

[0070] The power source assembly 23 and the negative pressure head 22 are connected by a negative pressure pipe, which is conducive to forming a certain negative pressure environment on the picking platform 20, thereby stabilizing the items on the picking platform 20 better through negative pressure adsorption. Especially for lighter items, they can be more conveniently transferred to the picking platform 20, and the stability of the items is enhanced during the movement of the picking platform.

[0071] When used outdoors, some lighter items may easily move and fall due to the influence of environmental wind speed and other factors. Negative pressure can be used to avoid this situation as much as possible, thereby improving the safety and stability of item transfer.

[0072] When moving objects, the negative pressure machine 231 forms a negative pressure environment at the negative pressure head 22 through the output hose 233, which is beneficial to the adsorption and stabilization of the objects and reduces the possibility of objects falling. When the objects reach the positioning and loading platform 30, the negative pressure state of the negative pressure head 22 is switched by controlling the valve 232, so as to facilitate moving the objects to the positioning and loading platform 30.

[0073] like Figure 1 , Figure 2 and Figure 3 As shown, the picking platform 20 includes an extension plate 24, and a transmission roller 25 is arranged on the extension plate 24, and the upper surface of the transmission roller 25 is higher than the upper surface of the picking platform 20;

[0074] A micro motor 241 is provided on the extension plate 24, and the output end of the micro motor 241 is connected to the transmission roller 25 through a coupling;

[0075] A sliding groove matching the extension plate 24 is provided on one side of the picking platform 20 , and a first electric push rod 242 is arranged in the sliding groove. After the extension plate 24 slides along the horizontal direction of the picking platform 20 , the transmission roller 25 movably contacts with the picking platform 20 .

[0076] The first electric push rod 242 drives the extension plate 24 to move horizontally on one side of the object-picking platform 20, which is beneficial to expanding the application range of the object-picking platform 20 and flexibly adjusting and using objects of different specifications, thereby improving the transportation efficiency of small-sized objects and improving the stability of the movement of large-sized objects;

[0077] At the same time, the micro motor 241 drives the transmission roller 25 to rotate on one side of the extension plate 24, which is conducive to pushing the object to move. When the object is transferred to the picking platform 20, it is conducive to driving the object to move toward the inner side of the picking platform 20, thereby improving the stability of the object placement. When the object is transferred to the positioning and loading platform 30, the transmission roller 25 performs rolling friction on the object, which is conducive to driving the object to move out and transfer it to the positioning and loading platform 30, thereby achieving the purpose of moving the object.

[0078] like Figure 1 and Figure 6 As shown, the positioning and loading platform 30 is provided with positioning blocks 32 located on both sides of the docking plate 31, and the positioning blocks 32 protrude from the upper surface of the positioning and loading platform 30 to form a limiting structure, and the picking platform 20 is movably in contact with the positioning blocks 32, so that the positioning blocks 32 move downward and are stored in the positioning and loading platform 30 to form a movable telescopic structure;

[0079] The lower surface of the positioning block 32 is provided with a telescopic rod 33 fixedly installed in the positioning loading platform 30, the telescopic rod 33 includes a telescopic tube sleeve 331 and a rod body 332, and a spring is fixedly installed at the connection between the rod body 332 and the telescopic tube sleeve 331;

[0080] A positioning sensor 34 is provided on the positioning loading platform 30 .

[0081] The positioning loading platform 30 facilitates positioning connection with the drone, thereby fixing the landing position of the drone, and thus positioning loading, which is convenient for automatic docking and loading of items when the drone returns, and can optimize the drone loading route, thereby improving the drone assembly efficiency.

[0082] When the picking platform 20 moves to the positioning and loading platform 30, the positioning block 32 is pushed down and stored in the positioning and loading platform 30 through the extension plate 24, and the telescopic rod 33 and the spring are compressed to push the items to the docking plate 31 through the extension plate 24. When the extension plate 24 is retracted, the spring rebounds and drives the rod body 332 to rise, causing the positioning block 32 to rebound to its initial position, which is beneficial to limit the items on the docking plate 31 and can reduce the movement or falling of the items.

[0083] The drone docks with the docking plate 31 through the positioning sensor 34, and grabs the items on the docking plate 31 through the gripper at the bottom of the drone to complete the automatic loading work.

[0084] like Figure 1 and Figure 2 As shown, a lifting assembly 26 connected to the object-picking platform 20 is disposed in the guide column 21, and the lifting assembly 26 is connected to the negative pressure head 22 through the object-picking platform 20;

[0085] The lifting assembly 26 includes a driving motor 261 fixedly arranged at the bottom of the guide column 21, a driving screw 262 is fixedly connected to the output end of the driving motor 261 through a coupling, the driving screw 262 is threadedly connected to a nut 263 movably connected to the object-picking platform 20, and fixed rods 264 are respectively arranged on both sides of the driving screw 262, and the nut 263 is connected to the fixed rod 264 through a connecting plate 265;

[0086] Among them, a second electric push rod 27 located on the outside of the guide column 21 is arranged on both sides of the connecting plate 265, the second electric push rod 27 is slidably connected to the guide column 21, and the output end of the second electric push rod 27 is interconnected with the negative pressure head 22 through a connecting rod 271, and the negative pressure head 22 translates along the width direction of the picking platform 20 to form a distance adjustment structure.

[0087] The lifting assembly 26 drives the picking platform 20 to adjust its height on the guide column 2, so as to facilitate taking out the items from each layer of the loading cabinet 10 and sending them to the positioning loading platform 30. The three-dimensional storage form is conducive to reducing the occupied space.

[0088] The driving motor 261 controls the movement of the nut 263 on the driving screw 262, driving the connecting plate 265 to slide on the driving screw 262 and the fixed rod 264, further driving the picking platform 20 to rise and fall, and at the same time, the connecting plate 265 drives the second electric push rod 27 to rise and fall together, so that during the lifting process of the picking platform 20, the negative pressure head 22 can be driven by the second electric push rod 27 to translate, thereby facilitating the adsorption and stabilization of the objects.
