[0028] The features and performance of this application will be further described in detail below with reference to the embodiments.
[0029] Example Please see Figures 1 to 8 This application provides a winding welding device, including a base 1, a feeding assembly for transporting windings, and a welding assembly 5 for welding windings. The feeding assembly and the welding assembly 5 are both disposed on the base 1, and the welding assembly 5 is located behind the feeding assembly. The aforementioned feeding assembly includes a support 2, a drive mechanism 3, and a feeding mechanism 4. Both the drive mechanism 3 and the feeding mechanism 4 are disposed on the support 2. The feeding mechanism 4 includes a feeding platform 41, which is disposed on the support 2. The drive mechanism 3 is connected to the feeding platform 41 in a transmission manner, and the drive mechanism 3 is used to drive the feeding platform 41 to rotate axially.
[0030] In this application, before soldering the winding element 100, multiple winding elements 100 are placed side by side on the same horizontal line. Then, the leads 101 at both ends of the multiple winding elements 100 are glued together with tape 102 to form a winding tape (e.g., Figure 4 (As shown). Place the winding tape on the feeding table 41, and simultaneously take the tinned copper wire 103 mechanically or manually, and place the tinned copper wire 103 on the winding tape, so that the tinned copper wire 103 is located on one end of the winding element 100 and perpendicular to the end lead 101 of the winding element 100. At this time, the intersection of the tinned copper wire 103 and any lead 101 is a solder point (e.g., Figures 5-7 (As shown). Welding assembly 5 is used to weld the tinned copper wire 103 to the lead wire 101 at each welding point. During this process, after welding assembly 5 completes the welding of one (or multiple) welding points, drive mechanism 3 drives the placement table 41 to rotate, rotating the welded winding tape portion out of the placement table 41 and rotating the subsequent winding tape portion to be welded onto the placement table 41, placing it below welding assembly 5, and then welding it again through welding assembly 5. This cycle is repeated until the welding operation of the entire winding tape is completed. The welded winding tape can be sent for subsequent cutting (the state of the winding tape after cutting is shown in the image). Figure 8 As shown, the cut winding components are welded together in pairs using tin-plated copper wire 103, and then potted.
[0031] Furthermore, in some embodiments of this application, a first gear 42 is provided around the circumferential sidewall of the material placement platform 41, and the first gear 42 is close to the welding assembly 5.
[0032] In the above embodiments, such as Figures 1-3,as well as Figure 4 As shown, there is a gap between the leads 101 of any two adjacent winding elements 100 in the winding tape, and this gap matches the spacing between every two teeth on the first gear 42; when the winding tape is placed on the feeding table 41, the teeth on the first gear 42 will pass into the gap between the leads 101 of any two adjacent winding elements 100 (as shown). Figures 6-7 (As shown). Thus, when the drive assembly drives the placement table 41 to rotate, the first gear 42 rotates coaxially, which causes the wound tape to move along the rotation direction of the first gear 42, thereby transferring the part that has been welded out of the placement table 41 and transferring the part to be welded into the placement table 41 for welding.
[0033] Furthermore, in some embodiments of this application, a second gear 43 is provided around the circumferential sidewall of the material placement platform 41. The number and direction of the teeth of the second gear 43 are the same as those of the first gear 42. The second gear 43 is located in front of the first gear 42 and forms an interval area with the first gear 42. The material placement platform 41 is provided with a welding area 44, which is located in the interval area.
[0034] like Figures 1-3 ,as well as Figure 6 , Figure 7 As shown, when the wound tape is placed on the feeding table 41, the welding point (the intersection of the tinned copper wire 103 and any lead wire 101) is located in the welding area 44, which is conducive to precise welding positioning.
[0035] Furthermore, in some embodiments of this application, a third gear 45 is provided around the circumferential sidewall of the material placement platform 41. The third gear 45 is far away from the welding assembly 5, and the number and direction of the teeth of the third gear 45 are consistent with those of the first gear 42 and the second gear 43.
[0036] like Figures 1-3 ,as well as Figure 6 , Figure 7 As shown, the number of teeth and the spacing of the first gear 42, the second gear 43 and the third gear 45 are the same, that is, the teeth of each of the three can be inserted into the gap between the lead wires 101 of two adjacent winding elements 100 to ensure the stable transport of the winding tape.
[0037] Furthermore, in some embodiments of this application, a groove 46 is provided around the circumferential sidewall of the material placement platform 41, and the groove 46 is located between the third gear 45 and the second gear 43.
[0038] like Figures 1-3 ,as well as Figure 6 , Figure 7As shown, when the winding tape is placed on the feeding table 41, the winding element 100 body can be embedded into the groove 46.
[0039] Furthermore, in some embodiments of this application, the cross-section of the aforementioned material placement platform 41 is circular.
[0040] Furthermore, in some embodiments of this application, the drive mechanism 3 includes a motor, which is mounted on the bracket 2 and is connected to the material placement platform 41 in a transmission manner.
[0041] Furthermore, in some embodiments of this application, the drive mechanism 3 includes a ratchet 31, a pawl 32, and a cam 33. The ratchet 31, the pawl 32, and the cam 33 are all disposed on the bracket 2. The motor is drivenly connected to the cam 33, the cam 33 is conventionally connected to the pawl 32, the pawl 32 is drivenly connected to the ratchet 31, and the ratchet 31 is drivenly connected to the material placement table 41.
[0042] Furthermore, in some embodiments of this application, the number of teeth of the ratchet 31 is half the number of teeth of the first gear 42.
[0043] Furthermore, in some embodiments of this application, the drive mechanism 3 operates in a 3-beat cycle, i.e., 1 beat of movement followed by 2 beats of pause; during movement, it drives the material placement table 41 to rotate to push the winding tape; during pause, the welding assembly 5 performs welding operations and resets. The first gear 42, the second gear 43, and the third gear 45 all have 90 teeth, and the ratchet 31 has 45 teeth; when the ratchet 31 pushes one tooth under the action of the pawl 32 and the cam 33, the first gear 42 / second gear 43 / third gear 45 simultaneously rotate two teeth.
[0044] Furthermore, in some embodiments of this application, the ratchet 31 is coaxially connected to the material placement table 41.
[0045] Furthermore, in some embodiments of this application, the welding assembly 5 includes a lifting mechanism 51 and a welding torch 52. The lifting mechanism 51 is disposed on the base 1, and the welding torch 52 is connected to the lifting mechanism 51 in a transmission manner. The lifting mechanism 51 is used to drive the welding torch 52 to move up and down, and the welding torch 52 is close to the material placement platform 41.
[0046] In the above embodiment, the lifting mechanism 51 drives the welding torch 52 to move up and down to facilitate welding operations and resetting.
[0047] In summary, this application provides a winding welding device. During use, multiple winding elements are first bonded together in parallel to form a winding tape. The winding tape is then placed on a feeding table, and welding is performed using a welding assembly. After each welding operation, a drive mechanism rotates the feeding table, moving the welded winding element away from the table and allowing the next winding element to be welded to move to the welding point, continuing the welding process. This cycle completes the welding operation for the entire winding tape. The welded winding tape can then be sent for subsequent cutting, potting, and other operations. This device enables automated winding welding, thereby reducing labor costs, improving work efficiency, ensuring welding quality, and facilitating large-scale production.
