[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0052] The process of welding manganese copper resistors is challenging. Specifically, when the metal base is placed in the bearing mold, the fin is placed at one end of the base, and then welded by the welder, the positioning accuracy of the fin is often affected by operating errors, resulting in the need for repeated positioning, which not only reduces production efficiency but also has a negative impact on product quality.

[0053] Although some production links have introduced automated equipment for welding, in actual operation, the uneven arrangement of metal plates and fins still leads to a decrease in welding quality. Therefore, an embodiment of the present invention provides a welding device for manganese-copper resistors to improve the accuracy and efficiency of welding.

[0054] like Figure 1 , Figure 5 and Fig. 9 As shown, in some embodiments, the welding equipment for manganese copper resistors includes a support component 2. The support component 2 serves as the supporting base of the equipment and not only plays a supporting role but also serves to connect the sorting component 1, the weldment bearing component 4 and the electric welding component 5.

[0055] The sorting component 1 is arranged on the upper part of the supporting component 2, and is mainly used for sorting and sorting the metal bottom sheet 301 and the fin 302 respectively.

[0056] It is worth noting that an upper dividing mechanism 110 and a lower dividing mechanism 170 are provided in the sorting component 1. The dividing mechanisms are connected via a rotating shaft 160. The upper dividing mechanism 110 is located at the upper part of the lower dividing mechanism 170 and is mainly used for sorting and sorting the fins 302. The lower dividing mechanism 170 is mainly used for sorting and sorting the metal bottom sheet 301.

[0057] Secondly, a bearing platform 401 is provided in the weldment bearing assembly 4, a mounting groove 406 is provided in the middle of the bearing platform 401, and a push plate 408 and a baffle 407 are provided on both sides of the mounting groove 406, respectively. The push plate 408 is slidably connected with the bearing platform 401. When the metal bottom plate 301 is welded with the fin 302 at the mounting groove 406 to form a resistor 3, the baffle 407 is in a high position, which plays a role in fixing the resistor 3 and preventing the position of the metal bottom plate 301 and the fin 302 from shifting. When the resistor 3 is welded, the baffle 407 moves downward and is in a low position, which is slightly lower than the height of the bottom of the mounting groove 406. The push plate 408 is pushed forward to push the resistor 3 out of the mounting groove 406, so that it is drawn out of the weldment bearing assembly 4 from the stripper plate 205, and the welding operation of a resistor 3 is completed.

[0058] It should be particularly noted that a first feed port 411 is provided at one end of the mounting groove 406, and the first feed port 411 is connected to the lower material distribution mechanism 170 via the first outer track 6. Specifically, after the metal bottom sheet 301 is sorted and sequenced by the lower material distribution mechanism 170, it is transferred by the first outer track 6 and enters the mounting groove 406 from the first feed port 411, at which time the top end of the metal bottom sheet 301 is against the other end of the mounting groove 406.

[0059] At the same time, a second feed port 410 is provided at the other end of the mounting groove 406, and the second feed port 410 is connected to the upper material distribution mechanism 110 through the second outer track 7. Specifically, after the fins 302 are sorted and arranged by the upper material distribution mechanism 110, they are transferred and turned by the second outer track 7, and fall from the second feed port 410 to the upper part of the metal bottom sheet 301, and are welded into a resistor 3 by the electric welding assembly 5.

[0060] like Figure 8 and Fig. 9 As shown, in some embodiments, the sorting assembly 1 is further provided with a cylinder 120 and a first motor 140. A cover plate 123 and a sealing plate 121 are respectively provided at both ends of the cylinder 120, and a partition plate 122 parallel to the cover plate 123 is provided at the center of the cylinder 120. An upper material distribution bin is formed between the cover plate 123 and the partition plate 122, and the upper material distribution mechanism 110 is arranged in the upper material distribution bin. A lower material distribution bin is formed between the partition plate 122 and the sealing plate 121, and the lower material distribution mechanism 170 is arranged in the lower material distribution bin. The partition plate 122 serves to separate the upper and lower material distribution bins and support the upper material distribution bin.

[0061] A second gear 150 is provided at the end of the rotating shaft 160 . The second gear 150 is connected to the first motor 140 through the first gear 130 . The first motor 140 drives the rotating shaft 160 to rotate. The rotation of the rotating shaft 160 completes the material dividing operation of the upper and lower material dividing mechanisms.

[0062] Furthermore, in some embodiments, the upper material dispensing mechanism 110 includes a first loading port 111 , a first rotating disk 112 and a first inner guide rail 113 .

[0063] Specifically, the first loading port 111 is arranged on the cover plate 123, and such a design can facilitate the loading of materials and improve the working efficiency. The fins 302 to be welded pass through the first loading port 111 and are stacked on the first rotating disk 112. The first rotating disk 112 is arranged on the upper part of the partition plate 122 and is welded and fixed to the rotating shaft 160. A first inner guide rail 113 is also arranged on the upper part of the first rotating disk 112, and the guide rail is fixedly connected to the inner wall of the cylinder 120 to ensure the stability of the first inner guide rail 113.

[0064] The function of the rotating shaft 160 is to drive the first rotating disk 112 to rotate. During the rotation, the fins 302 continuously enter the first inner guide rail 113. The first rotating disk 112 is also slidably connected to the inner wall of the cylinder 120 to ensure that the first rotating disk 112 can effectively drive the rotation of the fins 302.

[0065] In particular, the first inner guide rail 113 is designed to be spiral, which can improve the fluidity of the fins 302 and improve their efficiency in sorting and sorting. In addition, the upper surface of the first rotating disk 112 is also provided with a plurality of protrusions, which can make the fins 302 slightly vibrate up and down while the first rotating disk 112 rotates, which can further promote the movement of the fins 302.

[0066] Furthermore, in some embodiments, the lower material distributing mechanism 170 includes a second loading port 173, a second rotating disk 171 and a second inner guide rail 172. The second loading port 173 is welded and fixed to the outer wall of the cylinder 120, and the second loading port 173 is located at the lower part of the partition 122. The metal bottom sheet 301 enters the lower material distributing bin through the second loading port 173 and is stacked on the second rotating disk 171.

[0067] The second rotating disk 171 is disposed on the upper portion of the sealing plate 121, and the second rotating disk 171 is welded and fixed to the rotating shaft 160, and the rotating shaft 160 drives the second rotating disk 171 to rotate, and the second rotating disk 171 is slidably connected to the inner wall of the cylinder 120, so as to ensure that the second rotating disk 171 can effectively drive the metal bottom sheet 301 to rotate. The second inner guide rail 172 is disposed on the upper portion of the second rotating disk 171, and the second inner guide rail 172 is fixedly connected to the inner wall of the cylinder 120 to ensure the stability of the second inner guide rail 172.

[0068] In particular, the second inner guide rail 172 is designed to be spiral, which can improve the fluidity of the metal bottom sheet 301 and improve its efficiency in sorting and sorting. In addition, the upper surface of the second rotating disk 171 is provided with a plurality of protrusions, which can make the metal bottom sheet 301 slightly vibrate up and down as the second rotating disk 171 rotates, which can further promote the movement of the metal bottom sheet 301.

[0069] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the support assembly 2 includes an upper fixed plate 201 and a lower fixed plate 203, and a connecting column 207 is provided between the upper fixed plate 201 and the lower fixed plate 203. The connecting column 207 forms a stable structural frame with the upper fixed plate 201 and the lower fixed plate 203 to ensure the stability of the entire support assembly 2.

[0070] The upper fixing plate 201 is fixed to the cylinder 120 by welding. A connecting hole 208 is provided on the upper fixing plate 201 , and the hole is used to connect with the rotating shaft 160 .

[0071] A first support frame 202 is provided on the lower fixing plate 203 . The first support frame 202 is located at the lower part of the connecting hole 208 and provides a stable support platform for the first motor 140 , so that the first motor 140 can drive the rotating shaft 160 to rotate smoothly.

[0072] There are multiple slots 204, which correspond to the support columns 412 of the weldment bearing assembly 4, so as to ensure that the bearing platform 401 is stably placed on the support assembly 2 during the welding process. The unloading plate 205 corresponds to the baffle 407 and is used to collect the resistors 3 that have been welded, thereby improving work efficiency.

[0073] Two cross plates 206 are provided between the connecting posts 207 to fix the two outer rails. One of the cross plates 206 is fixedly connected to the first outer rail 6, and the other cross plate 206 is fixedly connected to the second outer rail 7. Such a design makes the whole structure more solid.

[0074] Furthermore, in some embodiments, the electric welding assembly 5 includes an upper welding head 501 and a lower welding head 502, and the upper welding head 501 and the lower welding head 502 are correspondingly arranged to ensure the accuracy and stability of the welding process.

[0075] The upper end of the upper welding head 501 is connected to the driving rod 505. The driving rod 505 is used to drive the upper welding head 501 to move up and down, thereby achieving precise welding of the manganese-copper resistor.

[0076] The driving rod 505 is fixedly connected to one end of the fixing rod 504, and the other end of the fixing rod 504 is welded and fixed to the connecting plate 503, and the connecting plate 503 is tightly connected to the lower fixing plate 203. Such a structural design enables the upper welding head 501 to be stably installed on the lower fixing plate 203, thereby improving the stability of the welding process.

[0077] The upper welding head 501 is provided with a fixing piece 506 , which is designed to be C-shaped and connects the long sides of the fins 302 to fix the fins 302 to prevent the position of the fins 302 from moving during the welding process.

[0078] The corresponding lower welding head 502 is fixedly connected to the lower fixing plate 203. This design can ensure that the lower welding head 502 remains stable during the welding process, thereby improving the welding quality.

[0079] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the weldment bearing assembly 4 further includes a second support frame 402 and a second motor 403. The second support frame 402 is arranged on one side of the bearing platform 401, and it provides a solid auxiliary support for the entire structure. The second motor 403 is arranged on the second support frame 402, and the output end of the second motor 403 is fixedly connected to the push plate 408, so that the push plate 408 can be moved as needed. The use of the second motor 403 allows the push plate 408 to move forward and backward as needed. After the resistor 3 is welded, the push plate 408 pushes the resistor 3 away from the installation slot 406, completing the automatic unloading of the resistor 3, which greatly improves the work efficiency.

[0080] The lower part of the baffle 407 is fixedly connected to one end of the first telescopic rod 409, and the other end of the first telescopic rod 409 is fixedly connected to the lower fixed plate 203. Such a structural design enables the baffle 407 to move up and down stably.

[0081] The support platform 401 is provided with an avoidance hole 405 , which is arranged corresponding to the lower welding head 502 , so that the welding process can be smoother and the welding problems caused by the interference of components can be avoided.

[0082] In addition, a plurality of support columns 412 are provided at the lower portion of the support platform 401 , and the plurality of support columns 412 are arranged in one-to-one correspondence with the plurality of slots 204 , so that the support platform 401 can be stably arranged on the lower fixing plate 203 , further enhancing the stability of the entire structure.

[0083] Finally, a blocking mechanism 404 is also provided on the supporting platform 401 . The blocking mechanism 404 is arranged on the same side as the push plate 408 and on the left side of the push plate 408 . The function of the blocking mechanism 404 is to prevent the fin 302 from falling.

[0084] The blocking mechanism 404 is provided with a second telescopic rod 4042 and a blocking plate 4041, the second telescopic rod 4042 is fixedly connected to the blocking plate 4041, and the blocking plate 4041 is connected to the second outer track 7. Specifically, after the resistor 3 is welded, the push plate 408 is pushed forward to push it away from the mounting groove 406, and at this time, the baffle 407 is driven by the first telescopic rod 409 to move downward to provide space for the unloading of the resistor 3, and the resistor 3 is unloaded by the unloading plate 205. In this process, the second telescopic rod 4042 pushes the blocking plate 4041 to extend forward, so that the blocking plate 4041 blocks the exit of the second outer track 7 to prevent the fin 302 from falling.

[0085] After the resistor 3 is pushed away, the second motor 403 drives the push plate 408 to move backward, and the subsequent metal base plate 301 moves forward, with the front end resting against the second feed port 410 of the mounting groove 406. The second telescopic rod 4042 drives the blocking plate 4041 to extend and retract backward, and the fin 302 falls from the exit of the second outer track 7 onto the metal base plate 301. The upper welding head 501 moves downward and works together with the lower welding head 502 to weld the fin 302 to the metal base plate 301.

[0086] like Figure 1 and Fig.10 As shown, in some embodiments, the first outer rail 6 is connected to the second inner guide rail 172 through a first connecting port, and the first connecting port is arranged on the cylinder 120. This first connecting port is arranged at the lower material bin. After the metal bottom sheet 301 is sorted by the second inner guide rail 172, it is transferred to the first outer rail 6 through the first connecting port.

[0087] Further, in some embodiments, the second outer rail 7 is connected to the first inner rail 113 through a second connection port, and the second connection port is provided on the cylinder 120. The second connection port is provided at the upper material bin, and the fins 302 are transferred to the second outer rail 7 through the second connection port after being sorted by the first inner rail 113. It should be particularly noted that the fins 302 are provided with long sides and short sides. At the second connection port, the fins 302 are sorted, and the long sides are at the bottom. At the spiral turning point of the second outer rail 7, the long sides are turned to the top, and finally at the exit, the short sides are welded to the metal bottom sheet 301 as a whole, completing the welding work of the resistor 3.

[0088] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
