[0002] In the field of drones, the welding of motor wires and ESC wires is a core process to ensure stable current transmission between the motor and the ESC. The quality of the welding directly affects the flight attitude stability and endurance of the drone.

[0003] Currently, the welding process between motor wires and ESC wires mainly relies on manual welding. Specifically, one person needs to use a clamp or their hand to hold the joint between the motor wire and the ESC wire, ensuring precise alignment of their metal cores; another person operates a welding torch to heat the solder, filling the joint gap with molten solder to form a solder joint. However, this welding method requires two people working together, resulting in high personnel costs for a single welding operation, high skill requirements for the operators, and low welding efficiency. Furthermore, the welding quality is inconsistent, with variations in welding time and solder joint size easily occurring, leading to poor consistency in the current transmission characteristics of the motor and ESC. Therefore, there is an urgent need to develop an automated welding device for welding motor wires and ESC wires. Utility Model Content

[0040] Please see Figures 1 to 10The image shows an automatic welding device according to this utility model, applied to the welding process between motor wires and ESC wires in a drone. The automatic welding device of this application includes a base 10, a first fixing component 20 and a second fixing component located at both ends of the base 10 along its length, a support component 40 located between the first fixing component 20 and the second fixing component, and a welding mechanism. The first fixing component 20 is used to fix the ESC 91, specifically including a first fixing block 21, a limiting block 22 located on the first fixing block 21 away from the support component 40, and a pressure plate 23 located on the first fixing block 21 near the support component 40. The bottom of the first fixing block 21 has a first through hole at each end. The first through hole is an oblong hole extending along the length of the base 10. The first fixing block 21 is fixed on the base 10 by bolts passing through the first through holes and threadedly connected to the top of the base 10. The advantage of the oblong hole design is that the position of the first fixing block 21 can be adjusted along the length of the base 10 according to the actual size of the ESC 91, which greatly improves the adaptability of the device to ESCs of different specifications. More specifically, in this embodiment, a protrusion is provided on one side of the first fixing block 21 along the width direction of the base 10, which is used to abut against the side of the ESC 91 to initially position the ESC 91 on the first fixing block 21.

[0041] The limiting block 22 has limiting through holes at both ends. The limiting through holes are oblong holes extending along the length of the base 10. Bolts pass through the limiting through holes and are threadedly connected to the top of the first fixing block 21, so that the limiting block 22 and the first fixing block 21 enclose a limiting space for fixing the ESC 91. By adjusting the position of the limiting block 22 on the first fixing block 21, the fixing requirements of ESCs of different thicknesses can be adapted, further enhancing the versatility of the first fixing component 20. The pressure plate 23 has multiple fixing grooves 231. The two ends of the pressure plate 23 are threadedly connected to the top surface of the first fixing block 21 near the support component 40 by bolts. Part of the pressure plate 23 is located above the support plate 42 of the support component 40, so that the fixing grooves 231 and the positioning grooves 421 enclose a fixing space for fixing the ESC wire 911, thereby limiting the position of the ESC wire 911 and preventing the ESC wire 911 from shifting due to external force during the welding process, ensuring the accuracy of the welding point.

[0042] The second fixing component is used to fix the motor 92, specifically including a second fixing block 31. The second fixing block 31 has second through holes at both ends. These second through holes are oblong holes extending along the length of the base 10. Bolts are threaded through these second through holes to connect the second fixing block 31 to the base 10, thus fixing the second fixing block 31 to the base 10. The oblong design of the second through holes allows the second fixing block 31 to be adjusted along the length of the base 10 to accommodate the fixing requirements of motors of different specifications. Furthermore, a positioning groove 311 is provided on the side of the second fixing block 31 near the support component 40. In practical applications, this positioning groove 311 is adapted to the circular protrusion structure on one side surface of the motor 92 to achieve the positioning of the motor 92 on the base 10. Simultaneously, an avoidance groove is provided at the end of the base 10 connected to the second fixing block 31 to prevent interference between the motor 92 and the base 10 during placement, ensuring the stability of the motor 92 installation.

[0043] The support assembly 40 is used to position and place the ESC cable 911 and the motor cable 921 to achieve alignment at the connectors of the ESC cable 911 and the motor cable 921. Specifically, the support assembly 40 includes a support plate 42 and support plates 41 disposed at both ends of the support plate 42. The end of the support plate 41 away from the support plate 42 is fixedly connected to the base 10. In this embodiment, the top of the support plate 41 is provided with a placement hole, and both ends of the support plate 42 are slidably disposed in the placement hole. The bottom end of the bolt passes through the support plate 41 and is fixedly connected to the end of the support plate 42 located in the placement hole. The shank of the bolt is threadedly connected to the support plate 41. In practical applications, by rotating the bolt, the end of the support plate 42 can be raised and lowered within the placement hole, thereby adjusting the height of the support plate 42. Furthermore, a nut is provided on the rod above the top surface of the support plate 41. After the height of the support plate 42 is adjusted by rotating the bolt, the nut located above the top surface of the support plate 41 can be tightened downwards, so that the lower surface of the nut fits tightly against the top surface of the support plate 41. The friction between the two can effectively prevent the bolt from loosening due to self-rotation caused by vibration and other factors, ensuring that the height of the support plate 42 remains stable during the welding process. Multiple positioning grooves 421 are provided at intervals along the length of the support plate 42 for positioning and placing the power switch wire 911 and motor wire 921 to be welded. In this embodiment, a welding protrusion is provided in the middle of the positioning groove 421, and its top surface is a concave arc surface structure for cooperating with the bottom end of the welding head 56 in the welding mechanism.

[0044] The welding mechanism includes a U-shaped connecting frame 51, a first cylinder 52 mounted on the horizontal plate of the U-shaped connecting frame 51, and a welding assembly connected to the telescopic rod of the first cylinder 52. The two vertical plates of the U-shaped connecting frame 51 are slidably connected to both sides of the base 10 in the width direction, allowing the welding mechanism to move along the length direction of the base 10 to facilitate the placement of the motor 92 and the ESC 91 on the base 10. In practical applications, the welding assembly is driven by the first cylinder 52 to rise and fall along the height direction of the base 10, enabling welding operations at the joints of the ESC wire 911 and the motor wire 921 located in the positioning groove 421, achieving automated welding and improving welding efficiency.

[0045] Furthermore, the welding assembly includes a fixed plate 54, a mounting plate 55 connected to the fixed plate 54, and multiple welding heads 56 disposed on the mounting plate 55. A connecting rod 541 is provided on the side of the fixed plate 54 facing away from the mounting plate 55, and the top end of the connecting rod 541 is fixedly connected to the telescopic rod of the first cylinder 52. A fixing groove is provided on the fixed plate 54 corresponding to the position of each welding head 56, and a spring 57 is provided in the fixing groove. One end of the spring 57 is fixedly connected to the bottom of the fixing groove, and the other end of the spring 57 elastically abuts against the top end of the welding head 56. This spring buffer structure can provide a certain buffering force when the welding head 56 contacts the wire joint, avoiding damage to the wire due to excessively fast descent speed or excessive pressure of the welding head 56, while ensuring appropriate pressure between the welding head 56 and the wire joint, which is beneficial to improving welding quality. In this embodiment, the bottom end of the welding head 56 is a concave arc surface structure, which corresponds to the concave arc surface of the welding protrusion. When welding, the two enclose each other to form a wrapping space that matches the shape of the wire, ensuring that the heat is concentrated at the joint, improving the tightness and uniformity of the welding, and avoiding the problems of inconsistent welding time and uneven weld size that are common in manual welding. This greatly improves the consistency of the current transmission characteristics of the motor 92 and the ESC 91, thereby ensuring the flight attitude stability and endurance of the UAV.

[0046] The welding mechanism in this application also includes a mounting box 71 and a temperature controller 72 located inside the mounting box 71. The mounting box 71 is fixed to the side of the vertical plate of the U-shaped connecting frame 51 by bolts. Correspondingly, each welding head 56 is equipped with a thermocouple 58 inside. The thermocouple 58 is electrically connected to the temperature controller 72 through wires to realize real-time detection and adjustment of the temperature of the welding head 56, ensuring that the welding head 56 is always kept within the optimal welding temperature range during the welding process, avoiding problems such as wire burnout due to excessive temperature or weak welding due to excessively low temperature.

[0047] The welding mechanism in this application also includes a guide assembly, which includes two guide rods 61 and linear bearings 62 adapted to the guide rods 61. The linear bearings 62 are located on the horizontal plate of the U-shaped connecting frame 51. The guide rods 61 are arranged along the height direction of the base 10. The bottom end of the guide rod 61 passes through the end of the fixed plate 54 and is fixedly connected to the end of the mounting plate 55 by bolts. When the first cylinder 52 drives the welding assembly to rise and fall, the guide rod 61 slides in the linear bearing 62, providing guidance for the movement of the welding assembly and effectively preventing the welding assembly from shifting or shaking during the rising and falling process. The guide rod 61 has a retaining spring 63 mounting groove on the circumference of its rod body above the top surface of the fixed plate 54. A retaining spring 63 is engaged in the retaining spring 63 mounting groove. The lower surface of the retaining spring 63 is in close contact with the top surface of the fixed plate 54 to limit the connection between the guide rod 61 and the fixed plate 54 and mounting plate 55, and to prevent relative displacement between the guide rod 61 and the fixed plate 54 and mounting plate 55, which would affect the welding accuracy.

[0048] The base 10 has sliders 11 on both sides in the width direction, and the sliders 11 extend along the length direction of the base 10. The two vertical plates in the U-shaped connecting frame 51 have connecting blocks 53 on their inner sides, and the side of the connecting block 53 away from the U-shaped connecting frame 51 has a groove 531 that matches the slider 11. The U-shaped connecting frame 51 can reciprocate along the length direction of the base 10 by sliding the slider 11 and the groove 531.

[0049] The automatic welding device in this application also includes a drive assembly, which includes a second cylinder 81, a mounting base 82 adapted to the second cylinder 81, and a U-shaped pull plate 83 fixedly connected to the telescopic rod of the second cylinder 81. The bottom of the base 10 has a placement groove along its length for placing the second cylinder 81. The mounting base 82 is fixedly connected to one side of the base 10 by bolts to ensure the stability of the second cylinder 81 installation. Two vertical sections of the U-shaped pull plate 83 are respectively arranged along the length of the base 10, and their ends are respectively fixedly connected to the bottom ends of the two vertical plates of the U-shaped connecting frame 51. When the telescopic rod of the second cylinder 81 extends or retracts, the U-shaped pull plate 83 drives the U-shaped connecting frame 51 to move along the length of the base 10, thereby adjusting the position of the welding mechanism.

[0050] Compared to existing technologies, the advantages of this automatic welding device are as follows: The combination of the base, first fixing component, second fixing component, and support component in this application is suitable for fixing ESCs and motors of different specifications on the base, exhibiting high applicability. Simultaneously, it effectively achieves positioning and alignment of the electrode wires and ESC wire connectors, eliminating the need for two-person operation and reducing labor costs. Automated welding is achieved through the welding mechanism; the multiple welding heads in the welding assembly allow for simultaneous welding of multiple sets of wires, significantly improving welding efficiency. Furthermore, the real-time temperature control via a temperature controller and thermocouple enables precise control of the welding head temperature, effectively avoiding temperature fluctuations caused by insufficient experience or operational negligence during manual welding. This eliminates the problems of excessively high temperatures burning the wires or excessively low temperatures causing weak welds, ensuring the quality stability of each weld point.
