Description

Technical Field

[0001] The invention relates to the field of welding equipment, in particular to automatic welding equipment for aluminum wire harnesses. Background Art

[0002] Automatic welding equipment can accurately control welding parameters such as welding current, voltage, time and pressure, ensuring that each welding point can achieve the best welding effect. This helps to improve the strength and reliability of the welded joints and reduce product defects and failures caused by welding quality problems. Compared with traditional manual welding, aluminum wire harness automatic welding equipment can complete welding tasks at a higher speed. For example, some advanced equipment can complete the welding of dozens or even hundreds of welding points per minute, greatly improving production efficiency.

[0003] Therefore, in actual use, the existing automatic welding equipment for aluminum wire harnesses cannot adjust the welding time and temperature according to the thickness of the terminal. At the same time, during the welding process, it cannot ensure that the terminal and the wire harness are in the same straight line, so that the wire harness and the terminal are in an inclined state after the welding is completed, which reduces the welding firmness and causes the movement of the terminal and the wire harness to easily cause friction damage to the wire harness, reducing the service life of the terminal and the wire harness after welding, and seriously causing irreparable losses due to electrical leakage after the wire harness is damaged.

[0021] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an automatic welding device for aluminum wire harnesses.

[0022] Embodiment 1, as Figure 1-Figure 6 As shown, an aluminum wire harness automatic welding device includes: The wire harness 20, the terminal 21 and the welding machine 6 are used to automatically weld and fix the wire harness 20 and the terminal 21. Before the welding machine 6 welds the wire harness 20 and the terminal 21, the terminal 21 has preliminarily fixed the wire harness 20. A welding room 1, a welding machine 6 is fixedly installed inside the welding room 1, a welding table 14 is rotatably connected inside the welding room 1, four clamping assemblies 2 are fixedly connected to the top of the welding table 14, the welding room 1 also includes a welding shell 5 placed on the ground, the welding machine 6 is fixedly installed on the bottom of the inner wall of the welding shell 5, a wire feeder 7 is fixedly installed on one side of the welding shell 5, a welding fume purifier 8 is fixedly installed inside the welding shell 5, a cooling air knife 9 is fixedly connected to one side of the welding shell 5, and the cooling air knife 9 is adapted to the clamping assembly 2; An infrared temperature sensor 11 is fixedly installed on one side of the welding machine 6, and the infrared temperature sensor 11 is adapted to the wiring harness 20 and the terminal 21. A welding frame 12 is fixedly connected to the bottom of the inner wall of the welding shell 5, and a rotating motor 13 is fixedly installed on the top of the welding frame 12. The output end of the rotating motor 13 is fixedly connected to the welding table 14, and the four sides of the welding table 14 are fixedly connected with a bag net 15, and the bag net 15 is adapted to the wiring harness 20; The clamping assembly 2 includes a vertical plate 17 fixedly connected to the top of the welding table 14, a clamp 18 is movably connected to the top of the vertical plate 17, a terminal 21 is fixedly connected to one side of the clamp 18, a conducting clamp 24 is slidably connected to the top of the vertical plate 17, the inside of the conducting clamp 24 abuts against the outside of the terminal 21, and a detection rod 25 is slidably connected to one side of the vertical plate 17; The clamping assembly 2 also includes four connecting plates 16 fixedly connected to the top of the welding table 14, one side of the connecting plate 16 is fixedly connected to one side of the adjacent vertical plate 17, the bottom of the connecting plate 16 is fixedly connected to a spring clip 19, the spring clip 19 is adapted to the adjacent wiring harness 20, the top of the connecting plate 16 is fixedly connected to a card plate 22, the card 18 is movably plugged into one side of the card plate 22, the top of the connecting plate 16 is fixedly connected to a driving cylinder 54, the output end of the driving cylinder 54 is fixedly connected to a cylinder clamp 23, the cylinder clamp 23 is slidably connected to the top of the connecting plate 16, and both sides of the outer wall of the conductive clamp 24 are fixedly connected to both sides of the inner wall of the cylinder clamp 23.

[0023] By setting the above-mentioned structure, the wiring harness 20 and the terminal 21 can be welded in batches. Specifically, the worker first clamps the terminal 21 with the wiring harness 20 on the clamp 18, and then starts the driving cylinder 54. The driving cylinder 54 drives the cylinder clamp 23 to clamp, and the clamping of the cylinder clamp 23 drives the conductive clamp 24 to move, and the conductive clamp 24 moves to fix the terminal 21. It is worth mentioning that the conductive clamp 24 is made of metal parts and forms a welding circuit with the welding machine 6. After the conductive clamp 24 clamps the terminal 21, the wiring harness 20 is clamped inside the spring clamp 19, and the wiring harness 20 and the terminal 21 are fixed respectively, and the excess wiring harness 20 is placed inside the net 15 thereunder, and the rotating motor 13 is started. The output end of the rotating motor 13 rotates to drive the welding table 14 to rotate, and the rotation of the welding table 14 drives the clamping assembly 2 thereon to rotate. The clamping assembly 2 fixed with the wire harness 20 and the terminal 21 is rotated to the depth of the welding room 1 and adapted to the welding machine 6. At this time, the welding machine 6 and the infrared temperature sensor 11 are started to weld and fix the wire harness 20 and the terminal 21. During the welding process, the infrared temperature sensor 11 can effectively detect the welding condition of the wire harness 20 and the terminal 21 to improve the welding accuracy. During the welding process, the welding smoke purifier 8 is started to effectively filter the welding smoke. After the welding is completed, the rotating motor 13 is started again. The output end of the rotating motor 13 drives the welding table 14 to rotate. At this time, the wire harness 20 and the terminal 21 on the clamping assembly 2 after welding are adapted to the cooling air knife 9, and the cooling air knife 9 is started to cool the wire harness 20 and the terminal 21 after welding. After the cooling is completed, the welding table 14 is rotated again to facilitate the staff to take it; It is worth mentioning that by setting up four groups of clamping components 2, the welding room 1 can still weld and cool the remaining welded parts while the workers are taking the welded parts, which greatly reduces the working time and improves the working efficiency. At the same time, the welding smoke purifier 8 is provided with a variety of templates to adapt to terminals 21 of various shapes, and can fix terminals 21 of various shapes.

[0024] Embodiment 2, as Figure 5-Figure 10As shown, an automatic welding device for aluminum wire harness, based on embodiment 1, includes a detection mechanism 3, the detection mechanism 3 includes a square frame 32 arranged symmetrically with the conductive clamp 24, two pressure sensors 38 and a detection pad 34 are slidably connected inside the square frame 32, and a distance sensor 35 is fixedly connected to one side of the detection pad 34, and the detection ends of the distance sensor 35 and the two pressure sensors 38 are adapted to the outside of the wire harness 20; The detection rod 25 slides in the middle of the conducting clip 24, a telescopic head 29 is fixedly connected to one side of the detection rod 25, a telescopic sleeve 27 is slidably connected to the outside of the telescopic head 29, a telescopic spring 28 is fixedly connected to one end of the telescopic head 29, one end of the telescopic spring 28 is fixedly connected to one side of the inner wall of the telescopic sleeve 27, a rubber pad 26 is fixedly connected to one side of the detection rod 25, and one side of the rubber pad 26 abuts against one side of the terminal 21; The detection mechanism 3 also includes a first fixed frame 30 fixedly connected to the inside of the detection rod 25, a first electric telescopic rod 33 is fixedly connected to the inside of the first fixed frame 30, one side of the detection pad 34 is fixedly connected to the telescopic end of the first electric telescopic rod 33, a square frame 32 is fixedly connected to the outside of the first fixed frame 30, both sides of the square frame 32 are fixedly connected to third fixed frames 36, the insides of the two third fixed frames 36 are fixedly connected to the second electric telescopic rod 37, and the telescopic ends of the two second electric telescopic rods 37 are fixedly connected to one side of a nearby pressure sensor 38.

[0025] By setting the above-mentioned structure, the thickness of the terminal 21 can be detected, and the welding strength of the wiring harness 20 and the terminal 21 can be improved. Specifically, in the process of clamping and fixing the terminal 21 by the conductive clamp 24, one side of the terminal 21 pushes the detection rod 25 to move, and the telescopic head 29 slides inside the telescopic sleeve 27, and the telescopic spring 28 is compressed. When the terminal 21 is clamped and fixed by the conductive clamp 24, the two second electric telescopic rods 37 and the first electric telescopic rod 33 are started. It is worth mentioning that the two second electric telescopic rods 37 and the first electric telescopic rod 33 are synchronously extended and retracted through the synchronous sensor, so that the telescopic distance of the two second electric telescopic rods 37 and the first electric telescopic rod 33 is always consistent. The extension of the two second electric telescopic rods 37 drives the pressure sensors 38 thereon to approach each other. When the two pressure sensors 38 touch the adjacent wiring harness 20, the two pressure sensors 38 detect the pressure values. At this time, the two second electric telescopic rods 37 and the first electric telescopic rod 33 are connected. The movable telescopic rod 37 and the first electric telescopic rod 33 both stop moving, and the distance sensor 35 is started. The distance sensor 35 detects the distance between the outside of the wiring harness 20 and the detection pad 34. This distance represents the thickness of the terminal 21. More specifically, since the square frame 32 is arranged symmetrically below the conductive clamp 24, the two pressure sensors 38 can accurately control the wiring harness 20 here at the exact center position below the terminal 21. When the terminal 21 is welded, its thickness has a certain relationship with the welding time. The thicker the terminal 21, the more metal content per unit volume, and the longer time required for heat to be transferred from the outside to the inside of the terminal 21. For thin terminals 21, the heat transfer is faster and the welding time is relatively short. If the welding time is too long, the terminal 21 may overheat or even burn out. By detecting the thickness of the terminal 21, the welding time and welding power of the welding machine 6 can be accurately adjusted to improve the welding quality of the welding machine 6.

[0026] The clamping mechanism 4 includes an arc block 42 slidably connected to one side of the detection rod 25, and three detection plates 47 are movably connected inside the arc block 42, and the detection plates 47 are adapted to the outside of the wiring harness 20; The clamping mechanism 4 also includes a second fixed frame 31 fixedly connected to the inside of the detection rod 25, a third electric telescopic rod 40 is fixedly connected to the inside of the second fixed frame 31, the telescopic end of the third electric telescopic rod 40 is fixedly connected to an arc frame 41, an arc block 42 is rotatably connected to the inside of the arc frame 41, three fourth electric telescopic rods 43 are fixedly connected to the inside of the arc block 42, the telescopic ends of the three fourth electric telescopic rods 43 are all provided with detection shells 46, the telescopic ends of the three fourth electric telescopic rods 43 are all fixedly connected to ball heads 44, one side of the three detection shells 46 is provided with ball grooves 45, and the three ball heads 44 are all movably connected to the inside of the adjacent ball grooves 45; A detection motor 48 is fixedly installed on the bottom of the inner wall of the detection shell 46, and a threaded rod 49 is fixedly connected to the output end of the detection motor 48. A nut slider 50 is screwed onto the external thread of the threaded rod 49, and a tension detection device 51 is fixedly installed on the top of the nut slider 50. The detection end of the tension detection device 51 is fixedly connected to a connecting block 52, and the connecting block 52 is fixedly connected to one side of a nearby detection plate 47.

[0027] A tooth groove 39 is formed on the outside of the arc block 42 . Two driving motors 53 are fixedly mounted on the top of the arc frame 41 . Gears 10 are fixedly connected to the output ends of the two driving motors 53 . The two gears 10 are meshed with the tooth groove 39 .

[0028] Furthermore, in the above scheme, by setting the above structure, the welding quality of the wiring harness 20 and the terminal 21 can be improved, the wiring harness 20 and the terminal 21 can be avoided from being tilted, the welding firmness can be improved, and the wiring harness 20 and the terminal 21 can be avoided from being damaged by mutual friction during later use, thereby improving the service life of the welding wiring harness 20 and the terminal 21, and at the same time, the welding wiring harness 20 and the terminal 21 are firmly detected. Specifically, when the distance sensor 35 detects a value, the third electric telescopic rod 40 is started at this time, and the telescopic end of the third electric telescopic rod 40 drives the arc frame 41 to move according to the value detected by the distance sensor 35, and aligns the center of the arc block 42 with the center of the wiring harness 20. At this time, the three fourth electric telescopic rods 43 are started, and the telescopic ends of the three detection pads 34 respectively drive the detection plates 47 thereon to approach the wiring harness 20 and abut against the outside of the wiring harness 20. At this time, the detection mechanism 3 is returned to its position, and the detection motor 48 is started. The output end of the detection motor 48 drives the threaded rod 49 to rotate, and the rotation of the threaded rod 49 drives the nut slider 50 to move, and the movement of the nut slider 50 drives The tension detection device 51 moves, and the movement of the tension detection device 51 drives the connection block 52 to move, and the movement of the connection block 52 drives the detection plate 47 to slide downward. When the tension detection device 51 detects a tension value, the detection motor 48 is turned off. At this time, the wire harness 20 and the terminal 21 are coaxially arranged, and the wire harness 20 and the terminal 21 can be effectively welded. After the welding is completed and cooled by the cooling air knife 9, the three fourth electric telescopic rods 43 are started to extend and retract, and the wire harness 20 and the terminal 21 are arranged at an angle, and the two drive motors 53 are started. The output ends of the two driving motors 53 respectively drive the gears 10 thereon to rotate, and the two gears 10 rotate and drive the arc block 42 meshing therewith to rotate. At this time, the three tension detection devices 51 can detect the tension value of the wire harness 20 when the wire harness 20 swings. When the wire harness 20 and the terminal 21 are welded at an angle, the three tension detection devices 51 will detect that the tension value on the inclined side is significantly lower than the tension value at other angles. At this time, it means that the wire harness 20 and the terminal 21 are abnormally welded, and the worker can take them out and handle them separately.

[0029] Working principle of the present invention: when welding is required, the worker first clamps the terminal 21 with the wiring harness 20 on the clamping piece 18, and then starts the driving cylinder 54, which drives the cylinder clamp 23 to clamp, and the clamping of the cylinder clamp 23 drives the conducting clamp 24 to move, and the conducting clamp 24 moves to fix the terminal 21. It is worth mentioning that the conducting clamp 24 is made of metal parts and forms a welding circuit with the welding machine 6. When the conducting clamp 24 clamps the terminal 21, the wiring harness 20 is clamped inside the spring clamp 19, and the wiring harness 20 and the terminal 21 are fixed respectively, and the excess wiring harness 20 is placed inside the bag net 15 thereunder, and the rotating motor 13 is started. The output end of the rotating motor 13 rotates to drive the welding table 14 to rotate, and the rotation of the welding table 14 drives the clamping assembly 2 thereon to rotate, and the wiring harness 20 and the terminal 21 are fixed. The clamping assembly 2 of the terminal 21 rotates to the depth of the welding room 1 and is adapted to the welding machine 6. At this time, the welding machine 6 and the infrared temperature sensor 11 are started to weld and fix the wire harness 20 and the terminal 21. During the welding process, the infrared temperature sensor 11 can effectively detect the welding conditions of the wire harness 20 and the terminal 21 to improve the welding accuracy. During the welding process, the welding smoke purifier 8 is started to effectively filter the welding smoke. After the welding is completed, the rotating motor 13 is started again. The output end of the rotating motor 13 drives the welding table 14 to rotate. At this time, the wire harness 20 and the terminal 21 on the clamping assembly 2 after welding are adapted to the cooling air knife 9, and the cooling air knife 9 is started to cool the wire harness 20 and the terminal 21 after welding. After the cooling is completed, the welding table 14 is rotated again to facilitate the staff to take it; In the process of clamping and fixing the terminal 21 by the conductive clamp 24, one side of the terminal 21 pushes the detection rod 25 to move, the telescopic head 29 slides inside the telescopic sleeve 27, and the telescopic spring 28 is compressed. When the terminal 21 is clamped and fixed by the conductive clamp 24, the two second electric telescopic rods 37 and the first electric telescopic rod 33 are started at this time. The two second electric telescopic rods 37 extend to drive the pressure sensors 38 thereon to approach each other. When the two pressure sensors 38 both touch the adjacent wiring harness 20, the two pressure sensors 38 detect the pressure values. At this time, the two second electric telescopic rods 37 and the first electric telescopic rod 33 both stop moving, and the distance sensor 35 is started. The distance sensor 35 detects the distance between the outside of the wiring harness 20 and the detection pad 34. This distance represents the thickness of the terminal 21, so that the welding time and welding power of the welding machine 6 can be accurately adjusted by detecting the thickness of the terminal 21, thereby improving the welding quality of the welding machine 6. When the distance sensor 35 detects a value, the third electric telescopic rod 40 is started. The telescopic end of the third electric telescopic rod 40 drives the arc frame 41 to move according to the value detected by the distance sensor 35, and aligns the center of the arc block 42 with the center of the wiring harness 20. At this time, the three fourth electric telescopic rods 43 are started, and the telescopic ends of the three detection pads 34 respectively drive the detection plates 47 thereon to approach the wiring harness 20 and abut against the outside of the wiring harness 20. At this time, the detection mechanism 3 is returned and the detection motor 48 is started. The output end of the detection motor 48 drives the threaded rod 49 to rotate, and the rotation of the threaded rod 49 drives the nut slider 50 to move. The movement of the nut slider 50 drives the tension detection device 51 to move. The movement of the tension detection device 51 drives the connecting block 52 to move. The movement of the connecting block 52 drives the detection plate 47 to slide downward. When the tension detection device 51 detects a tension value, the detection is closed. The measuring motor 48, at this time the wiring harness 20 and the terminal 21 are coaxially arranged, the wiring harness 20 and the terminal 21 can be effectively welded, after the welding is completed and cooled by the cooling air knife 9, the three fourth electric telescopic rods 43 are started to extend and retract, the wiring harness 20 and the terminal 21 are arranged at an angle, and the two driving motors 53 are started, the output ends of the two driving motors 53 respectively drive the gears 10 thereon to rotate, the two gears 10 rotate and drive the arc block 42 meshing therewith to rotate, at this time the three tension detection devices 51 can detect the tension value of the wiring harness 20 when the wiring harness 20 swings, when the wiring harness 20 and the terminal 21 are welded at an angle, the three tension detection devices 51 will detect that the tension value on the inclined side is significantly lower than the tension value at other angles, which means that the wiring harness 20 and the terminal 21 are abnormally welded, and the worker can take them out and handle them separately.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
