[0024] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments of the specification;
[0025] Embodiment 1:
[0026] The present application provides a coil welding mechanism, comprising a processing table 1; a turntable 2 is rotatably mounted on the top of the processing table 1, a fixing mechanism 3 is mounted on the surface of the turntable 2, a welding structure 4 is mounted on one side of the top of the processing table 1, and a preheating mechanism 7 is mounted on one end of the top of the processing table 1;
[0027] The preheating mechanism 7 includes a processing rack 701, a vortex tube 702 and a uniform heating plate 703. The processing rack 701 is installed at one end of the top of the processing table 1, the vortex tube 702 is installed on the top of the processing rack 701, and the uniform heating plate 703 is installed on the inner top of the processing rack 701;
[0028] Specifically, Figure 1 , Figure 2 and Figure 3As shown, the turntable 2 is used to place and adjust the use position of the coil, the fixing mechanism 3 is used to limit the coil, the welding structure 4 is used to weld the coil, the preheating mechanism 7 is used to preheat the coil, and the vortex tube 702 is arranged on the top of the processing frame 701, and its heating end is connected to the supporting processing frame 701, and the air outlet of the vortex tube 702 is connected to the inside of the uniform heating plate 703. The operation of the vortex tube 702 will cause the compressed gas to expand in the nozzle, and then enter the inside of the vortex tube 702 along the tangential direction at a very high speed. When the airflow rotates at a high speed in the vortex tube 702, it is separated into two parts of airflow with unequal total temperature after vortex transformation. One end of it generates cold air and the other end generates hot air. The hot air generated by the vortex tube 702 will be transported to the inside of the processing frame 701 through the uniform heating plate 703, and then the coil between the fixing mechanism 3 on the surface of the turntable 2 can be uniformly preheated to avoid deformation of the coil due to direct welding in the later stage.
[0029] Furthermore, the fixing mechanism 3 includes a welding platform 301 and a limit block 302. The welding platform 301 is installed on the surface of the turntable 2, and the limit block 302 is provided on the surface of the welding platform 301.
[0030] Specifically, Figure 1 As shown, in order to limit the coil, four groups of welding tables 301 are located on the surface of the turntable 2 and are evenly distributed. Limiting blocks 302 are distributed at the four corners of the surface of the welding tables 301. The coil can be limited by the limiting blocks 302.
[0031] Further, a cleaning brush 9 is installed on the side of the processing frame 701;
[0032] Specifically, Figure 1 As shown, in order to process the coil before welding, when the turntable 2 drives the surface coil to rotate and move, the coil will pass through the bottom of the cleaning brush 9. The cleaning brush 9 can be used to process the attachments on the surface of the coil to avoid affecting the welding effect of the welding structure 4 on the coil in the later stage.
[0033] Further, the welding structure 4 includes a support frame 401, a telescopic rod 402 and a laser welding generator 403. The support frame 401 is installed on one side of the top of the processing table 1, the telescopic rod 402 is installed on the inner top of the support frame 401, and the laser welding generator 403 is installed on the movable end of the telescopic rod 402;
[0034] Specifically, Figure 1 As shown, in order to realize the welding of the coil, the telescopic rod 402 is set at the inner top of the support frame 401. Through the operation of the telescopic rod 402, the telescopic end of the telescopic rod 402 drives the laser welding generator 403 to move up and down, and then the laser welding generator 403 can work to weld the coil at the bottom.
[0035] Furthermore, a driving device 1 5 is installed at the bottom of the processing table 1 near the welding structure 4, a driving device 2 6 is installed on the top of the driving device 1 5, and a support frame 401 is connected to the top of the driving device 2 6;
[0036] Specifically, Figure 2 As shown, in order to adjust the use position of the welding structure 4, the drive device 1 5 and the drive device 2 6 have the same structure and adopt the existing linear slide rail structure. The drive device 1 5 moves horizontally and the drive device 2 6 moves forward and backward. The left and right, front and back use positions of the welding structure 4 can be adjusted by the drive device 1 5 and the drive device 2 6, so that the welding structure 4 can better weld the coil.
[0037] Furthermore, a second processing rack 8 is installed at one end of the top of the processing table 1 away from the first processing rack 701, and an air induction plate 801 is installed on the inner wall of the second processing rack 8;
[0038] Specifically, Figure 1 and Figure 4 As shown, in order to achieve a cooling effect on the coil after welding, the other end of the vortex tube 702 is connected to the air induction plate 801 inside the processing rack 8, and the cold air can be evenly transported out through the air induction plate 801, and then the coil after welding on the surface of the turntable 2 is cooled to avoid deformation of the coil.
[0039] Further, a detection device 10 is installed on the side of the processing rack 2 8;
[0040] Specifically, Figure 2 As shown, in order to detect the coil after welding, the detection device 10 is a camera device, which adopts the existing visual communication system. The detection device 10 can take pictures and capture the coil after welding, and then send the data to the external controller for comparison and identification, so as to detect whether the coil after welding is qualified.
[0041] Working principle: by placing the coil between the limit blocks 302, and then driving the coil to move as the turntable 2 rotates, when the turntable 2 drives the surface coil to rotate and move, the coil will pass through the bottom of the cleaning brush 9, and the attachments on the surface of the coil can be processed by the cleaning brush 9, and then the hot air generated by the vortex tube 702 will be transported to the inside of the processing frame 701 through the uniform heating plate 703, and the coil can be evenly preheated. Then, the bottom coil can be welded by the laser welding generator 403, and then the welded coil can be photographed and captured by the detection device 10 to detect whether it is qualified. At the same time, the cold air generated by the other end of the vortex tube 702 is transported to the inside of the air induction plate 801, and the cold air can be evenly transported out through the air induction plate 801, and then the coil welded on the surface of the turntable 2 is cooled.
[0042] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
