[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] In order to solve the technical problem that the temperature of the welding part after welding is very high, it takes a long time to cool naturally, and may burn the operator, the present invention provides a UAV frame welding equipment, which can achieve rapid cooling of the welding part after welding, eliminate safety hazards and improve production efficiency.

[0019] It should be noted that the UAV frame welding equipment described in the present invention is used for but not limited to welding UAV frames. For the convenience of explanation, in the present invention, only the application of the UAV frame welding equipment to welding UAV frames is taken as an example for explanation. The principle of using the UAV frame welding equipment for welding other products is essentially the same as the principle of welding UAV frames, which will not be elaborated here.

[0020] See also Figure 1 , Figure 1 This is a schematic structural diagram of a UAV frame welding device in one embodiment of the present invention. The UAV frame welding device includes a welding unit 1 and a cooling unit 2.

[0021] The welding unit 1 includes a welding table 11 and a welding gun 12. The welding table 11 is used to place the UAV frame, and the welding gun 12 is used to weld the UAV frames on the welding table 11 together.

[0022] The cooling unit 2 includes a fan 21, a first air duct 22, and an air outlet nozzle 23. The air outlet of the fan 21 is connected to the air outlet nozzle 23 through the first air duct 22. After welding, the air outlet nozzle 23 blows air to the welding part on the drone frame to cool it down quickly to a safe temperature. In order to cool down various parts on the drone frame, at least part of the first air duct 22 is a hose.

[0023] In some embodiments, a clamp is provided on the welding table 11 for clamping and fixing the UAV frame. The welding gun 12 adopts an existing welding gun model suitable for the UAV frame.

[0024] In some embodiments, the welding unit 1 further includes a box 13, the interior of the box 13 forms a welding operation space, and one side of the box 13 is opened for welding operations and placing and removing the drone frame, that is, Figure 1The opening is preferably located in the middle of the box 13, and the structure of the box 13 is present above and below, and the size of the opening is minimized without affecting the operation. The welding table 11 and the welding gun 12 are located in the box 13, and a placement rack is provided on the box 13 for placing the welding gun 12. The power supply line connected to the welding gun 12 passes through the box 13 to connect to an external power source. The box 13 forms a semi-enclosed space, providing a relatively stable welding environment and blocking most of the spattered welding slag.

[0025] In some embodiments, the welding unit 1 further includes a mounting seat 14, a rotating shaft 15 and a rotating mechanism 16. The mounting seat 14 is arranged in the box body 13 and fixedly connected to the inner wall of the box body 13. Only a small amount of the edge of the mounting seat 14 is connected to the box body 13, so that the welding slag can fall from the hole between the mounting seat 14 and the box body 13. The rotating shaft 15 is arranged vertically, and the lower end is rotatably connected to the mounting seat 14, such as by a bearing. The upper end of the rotating shaft 15 is fixedly connected to the welding table 11, and the rotating mechanism 16 is arranged directly below the welding table 11 so that the welding table 11 can provide protection for the rotating mechanism 16 and shield the rotating mechanism 16 when the welding slag splashes. The rotating mechanism 16 is connected to the rotating shaft 15 to drive the rotating shaft 15 to rotate, so that the welding table 11 and the UAV skeleton thereon rotate, so as to facilitate the welding of different parts of the UAV skeleton.

[0026] In some embodiments, the rotating mechanism 16 includes a first motor 161, a first gear 162, and a second gear 163. The first motor 161 is fixedly connected to the mounting seat 14, the rotating shaft of the first motor 161 is coaxially fixedly connected to the first gear 162, the second gear 163 is sleeved on the rotating shaft 15 and coaxially fixedly connected to the rotating shaft 15, and the first gear 162 and the second gear 163 are meshed and connected. The first motor 161 drives the rotating shaft 15 to rotate through the transmission of the first gear 162 and the second gear 163. In other embodiments, a gear set containing more gears can also be used to achieve different reduction ratios. Other rotation drive mechanisms can also be used to drive the rotating shaft 15 to rotate.

[0027] In some embodiments, the welding unit 1 further includes a blocking net 17 and a slag catcher 18. The blocking net 17 is arranged below the mounting seat 14 and fixedly connected to the box 13. When the drone frame or part of the structure accidentally falls off the welding table 11, the blocking net 17 can catch it to prevent the drone frame from being broken. The blocking net 17 should be flexible or elastic to absorb the impact of falling. The slag catcher 18 is arranged below the blocking net 17 and slidably connected to the box 13. The slag catcher 18 is an open container for catching the falling welding slag. The blocking net 17 has many holes, and the welding slag can pass through the blocking net 17 and fall into the slag catcher 18. It is easy to understand that the blocking net 17 should be made of high temperature resistant material. The bottom of the box 13 is also formed with an opening for taking and placing the slag catcher 18. The shape and size of the slag catcher 18 are adapted to the cross-section of the bottom of the box 13 to fully catch the welding slag.

[0028] In some embodiments, the air outlet nozzle 23 is located in the box body 13, and a placement rack for placing the air outlet nozzle 23 is provided on the side wall of the box body 13. The first air duct 22 runs through the box body 13. Preferably, the portion of the first air duct 22 located outside the box body 13 is a hard tube, and the portion located inside the box body 13 is a flexible tube, such as a corrugated tube, which can be stretched and bent, so as to blow to various parts of the drone frame.

[0029] In some embodiments, the cooling unit 2 further includes a second air duct 24, the air inlet end of the second air duct 24 is connected to the air outlet of the fan 21, and the air outlet end of the second air duct 24 is located at the upper part of the box body 13 and faces the welding platform 11. The second air duct 24 can cool down the entire UAV frame on the one hand, and on the other hand, it can blow off the welding slag and other debris on the welding platform 11 and make it fall into the slag receiver 18. The first air duct 22 is connected to the second air duct 24.

[0030] In some embodiments, the cooling unit 2 further includes a refrigeration device 25, the cold end of which is arranged in the second air duct 24 and between the fan 21 and the first air duct 22. The refrigeration device 25 can make the first air duct 22 and the second air duct 24 blow out cold air, which on the one hand enhances the cooling and temperature reduction capability of the air outlet nozzle 23, and on the other hand, the second air duct 24 blows out cold air into the box 13, playing a role similar to that of an air conditioner outlet, thereby improving the welding processing environment. The refrigeration device 25 can adopt a refrigeration principle similar to that of an air conditioner, including a compressor, a condenser, an evaporator, an expansion valve, etc., or a semiconductor refrigeration sheet can be used to provide a cold source.

[0031] In this embodiment, the operator manually operates the welding gun 12 and the air outlet nozzle 23. In other embodiments, two robotic arms may be provided in the box 13 to respectively drive the welding gun 12 to automatically weld and drive the air outlet nozzle 23 to automatically cool.

[0032] In some embodiments, the UAV skeleton welding equipment also includes a thermal imaging unit 3, which includes an infrared camera 31 and a display screen 32. The infrared camera 31 is arranged toward the welding table 32, and the infrared camera 31 is connected to the display screen 32 by signal, and the display screen 32 is used to display the picture captured by the infrared camera 31. The infrared camera 31 uses the invisible infrared rays (wavelength between 0.76 and 400 microns, also called heat rays) generated by the material for imaging, and the imaging results are different at different temperatures. By using the infrared camera 31 to shoot the welded UAV skeleton, the operator can intuitively see the high-temperature area on the UAV skeleton through the display screen 32, so as to accurately cool down the high-temperature area to avoid omissions. At the same time, the cooling effect can also be intuitively viewed through the display screen to avoid insufficient cooling.

[0033] See also Figure 2 , Figure 2 yes Figure 1 Schematic diagram of the local structure in. In some embodiments, the welding unit 1 also includes a track 19, which is annular and fixedly connected to the inner wall of the box body 13. The thermal imaging unit 3 also includes a slider 33 and a driving mechanism 34. The slider 33 is slidably connected to the track 19, and the driving mechanism 34 is used to drive the slider 33 to move along the track 19, and the infrared camera 31 is fixedly connected to the slider 33. The fixed infrared camera 31 is prone to shooting blind spots. The driving mechanism 34 drives the slider 33 to move in a circle along the track 19 and shoots around the drone frame, which can effectively eliminate the shooting blind spots.

[0034] Although the rotating mechanism 16 can drive the welding table 11 to rotate, achieving the same effect of eliminating blind spots in shooting, the rotation rate of the welding table 11 is generally low for the safety of the drone frame. The infrared camera 31 is light in weight and rotates faster, so the use of the infrared camera 31 to rotate can improve efficiency.

[0035] In some embodiments, the driving mechanism 34 includes a second motor 341, a third gear 342, and a ring gear 343. The second motor 341 is fixedly mounted on the slider 33, and the rotating shaft of the second motor 341 is coaxially fixedly connected with the third gear 342. The ring gear 343 is an annular shape identical to the track 19 and is fixedly connected to the inner wall of the box body 13, and the third gear 342 is meshedly connected with the ring gear 343. Through the meshing transmission of the third gear 342 and the ring gear 343, the second motor 341 can drive the slider 33 to move along the track 19, thereby driving the infrared camera 31 to surround the drone frame for shooting.

[0036] It is easy to understand that in the present application, various electrical appliances can be powered by wired, wireless or battery power.
