Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) manufacturing technology, specifically to a wing rotation lubrication device for UAV manufacturing. Background Technology

[0002] Drones are highly flexible and fast-moving aircraft that can fly at low altitudes through human or automated control. They are widely used in aerial photography, agriculture, reconnaissance and rescue, and other fields. Drones can be divided into fixed-wing drones and multi-rotor drones according to their models. Multi-rotor drones are loved by many people for their compact size and playability. Furthermore, multi-rotor drones can achieve functions such as hovering in the air, making their functionality far greater than that of fixed-wing drones.

[0003] Multirotor drones, by installing an array of small, lightweight wings, change the direction of thrust by altering the wing angle or motor speed. As a result, the wings of multirotor drones experience significant wear during operation. Lubrication is necessary during the manufacturing process of drone wings to facilitate subsequent installation and reduce wear caused by high-speed rotation. Therefore, to facilitate the lubrication step in drone wing manufacturing, we propose a wing rotation lubrication device for drone manufacturing.

[0004] The existing technology still has the following drawbacks in its use:

[0005] 1. Existing drone manufacturing wing rotation lubrication devices typically involve manual application of lubricating oil or grease using a hand-held brush or similar tool, followed by application to designated areas on the wing. This method is not only inefficient but also makes it difficult to precisely control the amount of lubricating oil or grease applied. Excessive application can lead to buildup, affecting the wing's weight, causing imbalance during drone operation, and impacting the heat dissipation of the drive motor. On the other hand, applying less than the standard amount results in insufficient lubrication, leading to excessive wing wear and consequently affecting the wing's lifespan.

[0006] 2. Existing wing rotation lubrication devices for UAV manufacturing can only coat lubricating oil or grease individually. However, different types of UAVs have different operating conditions and require different lubricating materials. To avoid affecting the performance of the lubricating materials, they cannot be mixed. Therefore, traditional lubrication devices are quite limited. If different lubricating materials need to be coated, multiple lubrication devices are required, which reduces the practicality and efficiency of the lubrication device.

[0007] In view of this, we propose a wing rotation lubrication device for UAV manufacturing to solve the existing problems. Summary of the Invention

[0010] The housing is located on top of the support roller and the drive roller. Two sets of toothed blocks are provided on the outer side of the housing.

A communicating vessel is welded to both ends of the first guide tube, and one end of the communicating vessel extends into the interior of the shell. A feeding pipe is welded to the end of the communicating vessel that extends into the interior of the shell.

[0012] The second guide tube is located on the outside of the shell. The second guide tube is a semi-circular hollow pipe. The second guide tube is installed on the front of the first guide tube, and there is a gap between the second guide tube and the first guide tube. A second feed pipe is welded to the front of the second guide tube, and a communicator extending into the shell is installed at both ends of the second guide tube.

[0013] The injection tube is located inside the housing. A corrugated pipe is fixedly installed at the end of the injection tube away from the communicating vessel. An extension tube that penetrates the support frame is installed at the end of the corrugated pipe away from the communicating vessel. A solenoid valve is welded inside the extension tube. Two sets of lubrication brushes are installed at the end of the extension tube away from the corrugated pipe. Several sets of forked brushes are provided on the side of the lubrication brushes, and each set of forked brushes contains three sets of independent capillary tubes. The lubrication brushes, forked brushes, and capillary tubes are all hollow tubes. The tip of the capillary tube is provided with a fine hole that communicates with the interior of the capillary tube.

[0014] Preferably, the first guide tube and the second guide tube are installed at staggered positions, and the angle between the leftmost end of the first guide tube and the rightmost end of the second guide tube is 1 degree.

[0015] Preferably, the four sets of lubricating brushes are located on the same longitudinal plane, and the angle between two adjacent sets of lubricating brushes is degrees.

[0016] Preferably, the drive roller has a triangular snap-fit ​​hole inside, and a set of drive shafts extending to the front of the bottom shell are snapped into the snap-fit ​​hole. A reciprocating motor is installed on the drive shafts extending to the front of the bottom shell, and one side of the reciprocating motor is fixedly connected to the front of the bottom shell by bolts.

[0017] Preferably, a drain hole is provided on one side of the bottom shell, and a discharge pipe is welded to the outer side of the bottom shell at the location of the drain hole. A control valve is installed at the connection between the discharge pipe and the bottom shell by bolts.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention features a lubricating brush installed at one end of an extension tube. The lubricating brush is used to coat the internal lubricating oil or grease. The lubricating brush is made of a soft material. After contacting the wing surface, it can complete the brushing action as the shell rotates. During the brushing process, the contact part between the lubricating brush and the wing is in a completely fitted state, which can avoid the formation of lubrication dead zones and improve the uniformity of lubricating material coating. The lubricating brush has a multi-component forked design, which can expand the effective area of ​​a single brushing. Compared with traditional brushing tools, it can avoid the brush head from clumping after contacting highly viscous lubricating materials, thus ensuring the working effect of the device in later use and increasing the practicality of the device.

[0023] 2. The present invention installs a first guide pipe and a second guide pipe on the outside of the shell respectively, and the first guide pipe and the second guide pipe are respectively connected to two sets of opposing injection pipes, so that two kinds of lubricating materials can be injected into the device at the same time to adapt to the lubrication requirements of different wings. Furthermore, the opposing installation of the two sets of injection pipes corresponding to each set of guide pipes can reduce the angle required for the overall rotation of the shell, thereby improving the overall working efficiency of the device.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1-6 As shown, the present invention proposes a wing rotation lubrication device for UAV manufacturing, comprising a first guide pipe 1, a housing 2, a second guide pipe 3, and a bottom shell 4. Two sets of support rollers 402 are mounted on one side of the bottom of the bottom shell 4 via bearing brackets. The bottom shell 4 provides mounting positions for surrounding components and collects waste materials dripping from the device, facilitating the unified treatment of lubricating material waste later. The support rollers 402 support one side of the bottom of the housing 2, thereby ensuring the stability of the housing 2 during rotation and preventing misalignment when the housing 2 operates inside the bottom shell 4. Regular swaying affects the working effect, and two sets of drive rollers 403 are installed on the bottom side of the bottom shell 4 away from the support roller 402 through the bearing frame. The support roller 402 can cooperate with the drive roller 403 to support the shell 2, so that the shell 2 can rotate stably on the top of the support roller 402 and the drive roller 403. The drive roller 403 can be driven to rotate back and forth by the reciprocating motor 405 on the front of the bottom shell 4. Then, the teeth on the outside of the drive roller 403 match the tooth block 201, pushing the shell 2 to rotate back and forth, thereby driving the lubricating brush 504 to perform the brushing action.

[0033] The housing 2, located on top of the support roller 402 and the drive roller 403, is a hollow cylindrical tube that provides mounting positions for surrounding components. When it rotates, it drives the internal components to rotate synchronously, facilitating rotational lubrication of the wing. Two sets of toothed blocks 201 are provided on the outer side of the housing 2. These blocks 201 can engage with the teeth on the outer sides of the support roller 402 and the drive roller 403, respectively. With the cooperation of the drive roller 403 and the support roller 402, the housing 2 is pushed to rotate, allowing adjustment of the lubrication position of the lubrication brush 504 on the wing. Four sets of support frames 202 are welded at equal intervals to the inner wall of the housing 2. A fixed ring is located near the center of the support frame 202, limiting the outer side of the extension tube 501. Two sets of support rods connect to the housing 2, ensuring the stability of the extension tube 501 during operation and preventing it from shaking when driving the lubrication brush 504. This further improves the effectiveness and stability of the device in rotating lubrication of the UAV wing.

[0034] The first guide pipe 1 is located on the outside of the housing 2. The first guide pipe 1 is a semi-circular hollow pipe. The first feed pipe 101 is installed on the front of the first guide pipe 1. The first guide pipe 1 can guide lubricating oil or grease into the communicating vessel 102, and then inject the lubricating oil or grease into the designated injection pipe 5 for lubrication. The communicating vessel 102 is welded to both ends of the first guide pipe 1, and one end of the communicating vessel 102 extends into the interior of the housing 2. The communicating vessel 102 can assist the lubricating material in the first guide pipe 1 or the second guide pipe 3 to enter the injection pipe 5, so that the lubricating material in the injection pipe 5 can be discharged from the lubrication brush 504 for brushing. The end of the communicating vessel 102 extending into the interior of the housing 2 is welded to the injection pipe 5. The diameter of the injection pipe 5 is larger than that of the first guide pipe 1 and the second guide pipe 3, which can slow down the flow speed of the lubricating material inside, so that the lubricating material can slowly flow out from the interior of the lubrication brush 504. In conjunction with the solenoid valve 503, the amount of lubricating material is precisely controlled to avoid the situation of too much or too little lubricating material during operation.

[0035] The second guide pipe 3 is located on the outside of the housing 2. The second guide pipe 3 can be separated from the first guide pipe 1, so that different types of lubricating oil or grease can be injected into the device. According to the different wings of the UAV, the device can select different types of lubricating oil or grease, avoiding the mixing of lubricating materials and affecting the lubrication effect. At the same time, it can increase the functionality and practicality of the device. The second guide pipe 3 is a semi-circular hollow pipe. The second guide pipe 3 is installed on the front of the first guide pipe 1, and there is a gap between the second guide pipe 3 and the first guide pipe 1. The front of the second guide pipe 3 is welded with a second feed pipe 301, and the two ends of the second guide pipe 3 are also installed with a connector 102 extending into the housing 2. The second guide pipe 3 is connected to the other two sets of injection pipes 5 through the connector 102, so that the lubricating material inside the second guide pipe 3 can enter the lubrication brush 504 corresponding to the second guide pipe 3, thereby facilitating the rotational lubrication of the wings by using the lubrication brush 504.

[0036] The injection pipe 5, located inside the housing 2, guides the lubricating oil or grease inside the communicating vessel 102 into the bellows 502, and then introduces the lubricating oil or grease into the extension pipe 501 through the bellows 502. The bellows 502 is fixedly installed at the end of the injection pipe 5 away from the communicating vessel 102. The bellows 502 provides a certain amount of extension space for the extension pipe 501 while connecting the injection pipe 5 and the extension pipe 501, allowing the device to conform to the wing surface for lubrication. It can also perform rotational lubrication on wings of various diameters. An extension pipe 501, penetrating the support frame 202, is installed at the end of the bellows 502 away from the communicating vessel 102. The extension pipe 501 is fixedly connected to one end of the bellows 502 via a solenoid valve 503, and two sets of lubrication brushes 504 are installed at the other end to guide the lubricating oil or grease slowly and evenly into the air. The lubrication brush 504 is used to lubricate the wing surface. An electromagnetic valve 503 is welded inside the extension tube 501. The electromagnetic valve 503 can be of type DN253250. The electromagnetic valve 503 can control the switch inside the extension tube 501, thereby controlling the flow of lubricating oil or grease inside according to the usage requirements of the device. Two sets of lubrication brushes 504 are installed at the end of the extension tube 501 away from the bellows 502. Several sets of forked brushes are provided on the side of the lubrication brush 504, and each set of forked brushes contains three sets of independent capillary tubes. The lubrication brush 504, the forked brushes and the capillary tubes are all hollow tubes. The tip of the capillary tube is provided with a fine hole communicating with the inside of the capillary tube. The lubrication brush 504 can rotate a certain angle with the rotation of the housing 2 and reciprocate, thereby reciprocating the brushing of material on the wing surface, so that the internal lubricating oil or grease can be evenly coated on the wing surface after extrusion.

[0037] Furthermore, the first guide tube 1 and the second guide tube 3 are installed at staggered positions, and the angle between the leftmost end of the first guide tube 1 and the rightmost end of the second guide tube 3 is 90 degrees. Through the cooperation of the first guide tube 1 and the second guide tube 3, lubricating oil or grease is provided to the four sets of lubrication brushes 504 respectively, so that the lubricating material of a specified type or viscosity can be evenly coated on the surface of the wing for rotational lubrication.

[0038] Furthermore, the four sets of lubrication brushes 504 are located on the same longitudinal plane, and the included angle between two adjacent sets of lubrication brushes 504 is 90 degrees. By pairing the four sets of lubrication brushes 504 together, after selecting the correct lubricating material, the lubrication brushes 504 can be rotated by rotating the housing 2, so that the lubrication brushes 504 can rotate and lubricate the wing after adhering to the wing surface.

[0039] Furthermore, the drive roller 403 has a triangular snap-fit ​​hole inside, and a set of drive shafts extending to the front of the bottom shell 4 are snapped into the snap-fit ​​hole. A reciprocating motor 405 is installed on the front of the bottom shell 4, and one side of the reciprocating motor 405 is fixedly connected to the front of the bottom shell 4 by bolts. After the drive shaft is connected to the reciprocating motor 405, the reciprocating motor 405 can be energized and rotated to drive the drive roller 403 to reciprocate. The drive roller 403 then engages with the toothed block 201 on the outside of the shell 2 to drive the shell 2 to rotate synchronously, so as to drive the four sets of lubrication brushes 504 to perform rotational lubrication processing. The reciprocating motor 405 can be of type SS4203A65A.

[0040] Furthermore, a drain hole is provided on one side of the bottom shell 4, and a discharge pipe 401 is welded to the outside of the bottom shell 4 at the location of the drain hole. A control valve is installed at the connection between the discharge pipe 401 and the bottom shell 4 by bolts. By rotating the control valve, the opening and closing of the discharge pipe 401 can be controlled, so that the waste inside the bottom shell 4 can be discharged and cleaned after the device is used, so as to avoid the accumulation of waste affecting the use of internal components.

[0041] Furthermore, the outer sides of the support roller 402 and the drive roller 403 are provided with teeth, and the teeth on the outer sides of the support roller 402 and the drive roller 403 match the toothed blocks 201 on the outer side of the housing 2. After the teeth on the outer sides of the support roller 402 and the drive roller 403 match the toothed blocks 201, on the one hand, the housing 2 is supported and anti-slip is prevented, thus preventing the housing 2 from sliding, and on the other hand, the housing 2 can be rotated, thereby enabling the device to rotate and lubricate the wing.

[0042] Furthermore, a set of fixing brackets 203 is welded to the top of the bottom shell 4 near the front position. The fixing brackets 203 can provide a position for the fixing clips 204 to ensure the stability of the fixing clips 204. The fixing brackets 203 are welded to the fixing clips 204 near the center of the shell 2. The top and bottom of the fixing clips 204 are wider than the middle part, and the two sides are concave clips. The wing can be inserted into the center of the fixing clips 204. The wing is clamped by the clips on both sides of the fixing clips 204, thereby fixing the wing and facilitating rotation and lubrication.

[0043] Furthermore, a mounting plate 404 is welded to the bottom of the bottom shell 4, and two sets of fixing bolts are installed on the inner sides of the mounting plate 404 through a threaded structure. The mounting plate 404 can be fixedly installed in a designated position by fixing bolts, thereby fixing the bottom of the device to a designated platform to ensure the stability of other components on top.

[0044] Working principle: After assembling and verifying the device, the first feed pipe 101 and the second feed pipe 301 are connected to the external feeding device, respectively, so that the lubricating material enters the injection pipe 5 through the first guide pipe 1 and the second guide pipe 3. The wing to be processed is inserted into the fixing clamp 204 for fixation, and the area of ​​the wing that needs lubrication is exposed to the position of the lubrication brush 504. The flow of lubricating material inside the injection pipe 5 is controlled by the solenoid valve 503, and the lubricating material inside the injection pipe 5 enters the extension pipe 501. The lubricant slowly overflows into the lubricating brush 504. The bellows 502 is pushed and extended by the internal pressure, causing the lubricating brush 504 to contact the wing surface. At the same time, the reciprocating motor 405 is energized and rotates, driving the drive roller 403 to reciprocate. The drive roller 403 then drives the housing 2 to reciprocate, causing the lubricating brush 504 to reciprocate and brush the wing surface, uniformly coating the wing surface with the specified lubricating material. After coating, the processed wing is taken out from the fixing clamp 204 to complete one processing cycle.

[0045] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
