Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wing processing, in particular to a variable wing of unmanned aerial vehicle and wing processing equipment. BACKGROUND

[0002] The wing of unmanned aerial vehicle is an important part of unmanned aerial vehicle. The wing produces pressure difference when air flows through the upper and lower surfaces through a specific shape (airfoil) and angle (angle of attack), thereby generating upward lift to support the unmanned aerial vehicle to fly in the air.

[0003] The wing of unmanned aerial vehicle is sprayed during processing, mainly based on the protection of the wing structure. The wing material (such as carbon fiber, aluminum alloy, glass fiber, etc.) is easily eroded by environmental factors (such as humidity, salt spray, chemicals), resulting in a decrease in structural strength. Spraying epoxy resin paint, anticorrosive paint, etc. can form a protective layer to isolate external corrosive media and significantly extend the service life of the wing. For example, the unmanned aerial vehicle flying in the marine environment or the chemical area, the wing is sprayed with anticorrosive coating as a standard configuration.

[0004] In the prior art, when the wing of unmanned aerial vehicle is sprayed, a clamp is used to clamp and fix the wing, and then a spraying device is used for spraying. For example, the patent document with the publication number CN221580936U discloses a spraying device for carbon fiber unmanned aerial vehicle wing, which discloses that the two sides of the support frame are hinged with clamping arms. However, when the wing is clamped and fixed by the clamping arm, the part of the wing surface in contact with the clamping arm is blocked, so that the spraying device cannot spray this part. After the unblocked part of the wing surface is sprayed, the paint surface needs to be dried, the direction of the wing needs to be adjusted and clamped and fixed again, and finally the unsprayed part needs to be sprayed. The whole process needs to be disassembled and assembled several times, and the paint surface needs to be dried after each spraying, which is low in efficiency. SUMMARY

DETAILED DESCRIPTION

[0019] The specific embodiments of the present application are described in detail below, but it should be understood that the scope of protection of the present application is not limited by the specific embodiments.

[0020] Example 1

[0021] As Figures 1-2 shown, the variable wing of the unmanned aerial vehicle provided by the embodiment of the present application comprises a wing main body 2, the wing main body 2 comprises a positioning sleeve shaft 201, and the outer edge surface of the positioning sleeve shaft 201 is circumferentially arranged with at least two groups of wing structures 203; specifically, the specific number of wing structures 203 in the embodiment is not limited, and can meet the actual application requirements. For example, the wing structure 203 of the embodiment is fixedly arranged on the positioning sleeve shaft 201 in two groups.

[0022] In the embodiment, the axial end of the positioning sleeve shaft 201 is provided with a through slot 202 for locking and fixing with the driving end of the driving device 101, and each driving device 101 is arranged on the unmanned aerial vehicle main body 1; it should be noted that the driving device 101 of the embodiment is provided with four groups, which are respectively fixed on the unmanned aerial vehicle main body 1, and the positioning sleeve shaft 201 of each wing main body 2 is locked and fixed with the driving end of the driving device 101, which can drive the wing main body 2 to rotate through the driving device 101. The driving device 101 adopts a servo motor of the prior art, and the specific model and principle thereof are not limited, which can meet the actual application requirements.

[0023] Example 2

[0024] A wing processing device for a drone variable-wing, used to process a drone variable-wing as described in Embodiment 1. Please refer to [link to related documentation]. Figures 3-6 It includes a processing table 3, on which a base plate 301 is fixedly arranged. The base plate 301 is symmetrically arranged on both sides for fixing the wing body 2. In this embodiment, both the first positioning part and the second positioning part include several sets of locking ends 409 arranged at equal intervals for insertion and positioning with the through groove 202. The locking ends 409 are provided with locking modules for locking the positioning sleeve shaft 201 onto the locking ends 409. Specifically, in this embodiment, when positioning and fixing the wing body 2, the through groove 202 of the wing body 2 can be fitted onto the locking ends 409, and then the positioning sleeve shaft 201 can be fixed onto the locking ends 409 by the locking modules to facilitate subsequent spraying.

[0025] In addition, in order to improve the processing efficiency of the wing body 2, this embodiment does not limit the number of locking ends 409, as long as it meets the actual application requirements. For example, each positioning part in this embodiment is provided with four sets of locking ends 409.

[0026] A spraying assembly is provided between the first positioning part and the second positioning part for spraying the positioned wing body 2. It can be explained that in this embodiment, when spraying the wing body 2, the wing body 2 is first positioned and fixed by the locking end 409 of the first positioning part, and then one side of the wing body 2 is sprayed by the spraying assembly. After spraying, the wing body 2 is then positioned and fixed by the locking end 409 of the second positioning part. Since the first and second positioning parts are symmetrically arranged on both sides of the spraying assembly, when the wing body 2 with one side already sprayed is fixed to the second positioning part, its unsprayed surface faces the spraying assembly, allowing for spraying of that surface. This embodiment does not require clamping arms to clamp and fix the wing body 2, thus eliminating the phenomenon of clamping arms obstructing the surface of the wing body 2. Both sides of the wing body 2 can be sprayed. During the spraying process, multiple disassembly and assembly are not required, which not only improves the uniformity of the spraying but also effectively increases the spraying efficiency.

[0027] As one implementation method of this embodiment, please refer to Figure 3 , Figure 5 as well as Figures 7-9The locking end 409 is provided with a cavity, and the locking module includes positioning grooves 410 arranged in a circumferential array on the locking end 409. A wedge-shaped seat 403 is embedded on one side of the positioning groove 410 close to the cavity. A support 704 is fixedly arranged on the wedge-shaped seat 403. The support 704 is fixed to the cavity wall through a first spring 702. The positioning part further includes a locking sleeve 407 fixedly connected to the locking end 409. A locking rod 7 is slidingly inserted into the locking sleeve 407. The locking rod 7 is connected to an adjusting mechanism that drives the locking rod 7 to slide in the locking sleeve 407. A plurality of groups of guide wheels 705 corresponding to the wedge-shaped seats 403 are arranged on one side of the locking rod 7 close to the locking end 409. An inclined surface 703 is arranged on the wedge-shaped seat 403 and in rolling abutment with the guide wheels 705. It can be explained that in the initial state, each wedge-shaped seat 403 is in the state of being embedded in the positioning groove 410. When the locking end 409 is embedded in the through groove 202, the locking rod 7 can be driven by the adjusting mechanism to slide in the locking sleeve 407 towards the locking end 409 in this embodiment. The locking rod 7 synchronously drives the guide wheels 705 to move. The guide wheels 705 press the wedge-shaped seats 403 through the inclined surface 703 to give the wedge-shaped seats 403 an action force away from the shaft center, so that the wedge-shaped seats 403 can pass through the through groove 202 and tightly fit with the groove wall of the through groove 202, thereby realizing the positioning effect. When it is needed to separate the wing main body 2 from the locking end 409, the adjusting mechanism drives the locking rod 7 to move away from the locking end 409, and the first spring 702 can drive the wedge-shaped seat 403 to reset.

[0028] It can be seen from Figure 3 , Figure 5 and Figure 7 that, in the process of spraying, in order to avoid splashing of the paint, two groups of side plates 302 are fixedly arranged on the two sides of the bottom plate 301 in a symmetrical manner. Two groups of limiting grooves 312 are fixedly arranged between the two groups of side plates 302 in a symmetrical manner. A baffle 303 is clamped in the limiting groove 312. A reserved groove 309 for embedding the locking sleeve 407 is arranged on the baffle 303. It can be explained that when the wing main body 2 is sprayed, the two groups of baffles 303 are embedded between the two groups of side plates 302 and the bottom is clamped with the limiting groove 312, so that the two groups of side plates 302 and the two groups of baffles 303 form a spraying space to avoid splashing of the spraying liquid.

[0029] In addition, when the baffle 303 is used for a period of time, it can be directly replaced, which is very convenient to operate.

[0030] In this embodiment, in order to position and support the locking sleeve 407, reference can be made to Figures 3-5 and Figure 7The first support 406 is fixed on the first blocking frame 405, and each locking sleeve 407 is arranged on the first support 406 away from one end of the locking head 409. The bottom plate 301 is further provided with a limiting plate 4, and the limiting plate 4 is provided with a limiting rod 401 slidingly connected with the first blocking frame 405. The limiting rod 401 is provided with a second spring 402, one end of the second spring 402 is fixed on the limiting plate 4, and the other end is fixed on the first blocking frame 405. Specifically, the limiting plate 4 and the limiting rod 401 can support the first blocking frame 405 and the first support 406, so that the center lines of the locking sleeves 407 are on the same horizontal plane.

[0031] As a further scheme of the embodiment, one end of the locking rod 7 away from the locking head 409 is fixed on the adjusting rod 5. The adjusting rod 5 is provided with a third spring 701, one end of the third spring 701 is fixed on the end of the locking sleeve 407, and the other end is fixed on the adjusting rod 5. The other end of the adjusting rod 5 away from the locking sleeve 407 is rotatably connected with the second support 503, and each second support 503 is fixed on the second blocking frame 504. The processing table 3 is further provided with a pushing part for driving the second blocking frame 504 to move towards the first blocking frame 405. The first blocking frame 405 is further provided with a locking electric cylinder 404, and the driving end of the locking electric cylinder 404 is provided with a clamping plate 408. It can be explained that when the locking rod 7 is driven to slide in the locking sleeve 407 towards the locking head 409, the pushing part can drive the second blocking frame 504 to move towards the first blocking frame 405. The second blocking frame 504 can drive the adjusting rod 5 to move through each second support 503 during the movement. The adjusting rod 5 drives the locking rod 7 to move towards the locking head 409. During the process, the adjusting rod 5 compresses the third spring 701 and generates elastic force. Then the clamping plate 408 can be driven by the locking electric cylinder 404 to descend and move to one side of the second blocking frame 504, so as to avoid the automatic reset of the second blocking frame 504 under the elastic force of the third spring 701. Correspondingly, when the pushing part is reset and the clamping plate 408 is driven by the locking electric cylinder 404 to rise, the third spring 701 can drive each component to reset synchronously.

[0032] It can be seen from the above that Figures 4-7The pushing part comprises a machining table 304 fixed on the machining table 3, a screw rod 305 is arranged in rotation on the machining table 304, one end of the screw rod 305 is fixed with an output end of a driving motor 306, two groups of nuts 307 are symmetrically screwed on the screw rod 305, a push plate 308 for driving the second baffle 504 to move is fixedly arranged on the two side nuts 307, and a clamping groove 310 for clamping with the clamping plate 408 is arranged on the push plate 308; it can be explained that when the wing main body 2 is locked and fixed, the driving motor 306 is started to drive the screw rod 305 to rotate, the push plate 308 is driven to move synchronously in the process that the nut 307 moves on the screw rod 305, and the second baffle 504 is driven to move by the push plate 308; It also needs to be explained that when the wing main body 2 is sprayed on one side positioning part, in order to automatically replace the wing main body 2 to the other side positioning part for spraying, in the embodiment, when the wing main body 2 is sprayed on the first positioning part, firstly, the locking module of the first positioning part is separated from the positioning sleeve shaft 201, secondly, the push plate 308 of the second positioning part is driven to move towards the baffle 303 by the screw rod 305, the spring stiffness of the third spring 701 of the embodiment is greater than that of the second spring 402, therefore, when the push plate 308 drives the second baffle 504 to move, the second baffle 504 drives the first support 406 to move synchronously through the adjusting rod 5, the locking sleeve 407 and the locking end 409 move synchronously driven by the first support 406, when the locking end 409 of the second positioning part contacts with the locking end 409 of the first positioning part, the locking end 409 of the second positioning part continues to move, the locking end 409 of the first positioning part and the wing main body 2 are synchronously pushed to move, when the positioning sleeve shaft 201 of the wing main body 2 moves to contact with the baffle 303, the wing main body 2 stops moving, therefore, the locking end 409 of the second positioning part can be embedded in the through groove 202 of the positioning sleeve shaft 201, at this time, the locking end 409 of the second positioning part and the locking sleeve 407 also move to the limit position, when the push plate 308 drives the second baffle 504 to move again, the locking rod 7 is pushed to slide in the locking sleeve 407 towards the locking end 409 by the second baffle 504 through the second support 503, so as to lock and fix the wing main body 2 again; then the clamping plate 408 is driven to descend to be embedded in the clamping groove 310 by the locking cylinder 404, so as to realize the effect of further locking; when the push plate 308 of the second positioning part resets, the locking end 409 of the two positioning parts resets under the elastic force of the second spring 402, and then the wing main body 2 is transferred to the locking end 409 of the second positioning part, and then the wing main body 2 is sprayed by the spraying assembly.

[0033] It also needs to be explained that, in the initial state, the two push plates 308 are respectively attached to the two second stoppers 504. Since the two nuts 307 move in the same direction, when the nut 307 of one set of positioning parts drives the push plate 308 to move towards the other set of positioning parts, the nut 307 of the other set of positioning parts also moves accordingly, so as to avoid interference when the two locking heads 409 move synchronously, and the stability is higher.

[0034] Further, please refer to Figures 3-5 and Figure 8 The spraying assembly comprises a spraying box 6 arranged between the first positioning part and the second positioning part. The bottom of the spraying box 6 is provided with a plurality of groups of spraying pipes 603 corresponding to the locking heads 409 one by one. The spraying pipes 603 are communicated with the spraying box 6 through liquid conveying pipes 605. A plurality of groups of nozzles 604 are uniformly arranged on the spraying pipes 603. One end of the spraying box 6 is connected with a servo spraying machine through a spraying pipe 601. The machining table 3 is also fixedly arranged with a lifting mechanism 311 for driving the spraying box 6 to lift. The rotating mechanism is used for driving the positioned wing main body 2 to rotate. It can be explained that, when the fixed wing main body 2 is sprayed, the lifting mechanism 311 is used to drive the spraying box 6 to lift, so as to adjust the bottom end of the spraying pipe 603 to move to the axis of the locking head 409. The servo spraying machine is started, and the paint can be conveyed to the nozzles 604 through the spraying box 6, the liquid conveying pipe 605 and the spraying pipe 601. At the same time, the wing main body 2 is driven to rotate by the rotating mechanism, and the spraying is realized during the rotation. Correspondingly, the spraying pipe 603 only needs to move to the axis of the locking head 409 in the embodiment, so that the spraying range is also above the axis of the locking head 409, so as to avoid the spraying liquid from splashing out of the reserved groove 309.

[0035] In addition, the lifting mechanism is arranged in the embodiment, so that when the wing main body 2 needs to be fed or discharged, the spraying pipe 603 can be adjusted to rise to a certain height by the lifting mechanism, so as to facilitate the feeding and discharging. The lifting mechanism of the embodiment can adopt a synchronous belt transmission mechanism, which is the prior art, and the specific type and structure are not limited.

[0036] Specifically, the rotating mechanism comprises first gears 501 fixed on the adjusting rods 5, each first gear 501 is in mesh with a first rack 313, and each first rack 313 is fixedly connected through a connecting plate. A second adjusting motor 502 is fixed on one of the second supports 503, and the output end of the second adjusting motor 502 is fixed with the adjusting rod 5. Each first support 406 is fixed with a T-shaped sliding rail 411, and the first rack 313 is slidably connected with the T-shaped sliding rail 411 through a T-shaped sliding seat. It can be explained that when the wing main body 2 is rotatingly sprayed, the second adjusting motor 502 can drive one group of adjusting rods 5 to reciprocating rotate, and in the rotating process of the one group of adjusting rods 5, the first rack 313 can drive the other groups of adjusting rods 5 to synchronously reciprocating rotate. The embodiment does not need to set multiple servo devices to drive the wing main body 2 to rotate, which not only reduces the cost, but also improves the synchronism and stability.

[0037] It also needs to be explained that since the adjusting rod 5 and the locking sleeve 407 are fixedly connected through the third spring 701, the adjusting rod 5 can drive the locking sleeve 407 to synchronously rotate in the rotating process. Correspondingly, a slidingly clamped guide groove and guide seat can be arranged between the adjusting rod 5 and the locking sleeve 407 to further improve the stability of the synchronous movement of the two.

[0038] As an embodiment of the present embodiment, when the wing main body 2 is transferred from one side positioning part to the other side positioning part, in order to adjust the direction of the spray head 604, please refer to Figure 8 Each infusion pipe 605 is rotatably connected with the spraying box 6, the second gear 606 is fixed on the infusion pipe 605, each second gear 606 is in mesh with a second rack 607, and each second rack 607 is fixedly connected through a connecting plate. A horizontal electric cylinder 602 is further fixed on the bottom of the spraying box 6, and the driving end of the horizontal electric cylinder 602 is fixed with the second rack 607. It can be explained that when the direction of the spray head 604 is adjusted, the horizontal electric cylinder 602 can be started to drive the second rack 607 to move, and the second rack 607 can drive each infusion pipe 605 and the spraying pipe 603 to rotate through meshing with the second gear 606, so as to change the angle of the spray head 604.
