Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and in particular relates to an electrical wire welding device. Background Technology

[0002] In the field of electronics manufacturing, it is often necessary to reliably connect and mechanically fix circuit boards directly to the exposed cores of electrical wires at one end, a process known as circuit board-wire core soldering. This process typically involves multiple steps: wire pretreatment, circuit board loading, alignment of the treated wires with the circuit board, and then soldering and fixing the wire cores to the circuit board at the solder joints on a soldering machine.

[0003] The above-mentioned processes often employ a separate operation mode, relying on manual operation to move the wires with exposed cores from the wire handling station to the circuit board next to the soldering station for initial positioning. Manual handling and positioning of the wires affects overall production efficiency and operational errors, thereby affecting soldering accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a wire welding equipment that solves the problem of the existing separate operation mode for welding wires and circuit boards, which requires manual handling and positioning of wires, affecting production efficiency and welding accuracy.

The circuit board feeding device is located on the other side of the frame and includes a circuit board feeding mechanism, a circuit board transfer mechanism, and a circuit board limiting mechanism. The circuit board transfer mechanism is used to transfer the circuit board from the circuit board feeding mechanism to the circuit board limiting mechanism. The circuit board limiting mechanism is located beside the wire clamping station at the end of the conveyor belt and is used to limit the circuit board and form a welding station.

[0009] Furthermore, the peeling mechanism includes a slide rail, a mounting base, a second lifting member, a second raising member, a first movable plate, a second movable plate, a first scraper, and a second scraper. The slide rail is mounted on the frame and perpendicular to the conveyor belt. The mounting base is slidably connected to the slide rail via a first translation member. The second lifting member is located at the top of the mounting base, and its output end is connected to the first movable plate. The second raising member is located at the bottom of the mounting base, and its output end is connected to the second movable plate. The first and second movable plates are arranged vertically opposite each other. The first and second scrapers are respectively located on the side of the first and second movable plates near the clamping station.

[0010] Furthermore, a pressing mechanism is provided on one side of the peeling mechanism. The pressing mechanism is located directly above the conveyor belt and includes a third lifting component and a pressing block. The output end of the third lifting component is connected to the pressing block and is used to drive the pressing block to move down and press the wire so that it is flat and positioned in the wire clamping station.

[0011] Furthermore, the circuit board transfer mechanism includes a support base, a second translation component, a fourth lifting component, and an adsorption component. The support base is fixedly mounted on the frame. The fourth lifting component is mounted on the support base and connected to the second translation component.

[0012] Furthermore, the welding device includes a welding head, a fifth lifting component, and a solder bar conveying assembly. The fifth lifting component is located above the welding station and connected to the welding head, so that the welding head faces the welding station.

[0013] Furthermore, the welding device also includes a recycling component, which includes a recycling tube, a moving clamp, a sixth translation component, and a negative pressure component. The sixth translation component is mounted on the frame and its output end is connected to the moving clamp. The moving clamp is used to hold the outer periphery of the recycling tube.

[0016] The wire is first loaded into the clamping station, where it is conveyed by a conveyor belt through a cutting mechanism, a stripping mechanism, and a wire trimming mechanism. The cutting mechanism cuts the wire at the clamping station, creating a flat end face. The wire then moves to the stripping mechanism, where the outer insulation is cut. The wire then passes through the stripping mechanism, where the cut insulation is peeled off, exposing the wire core. Simultaneously, the circuit board transfer mechanism removes the circuit board from the circuit board loading mechanism and places it on the circuit board positioning mechanism. The exposed wire is then conveyed to the soldering station of the circuit board positioning mechanism, where the soldering device precisely solders the wire core to the corresponding solder points on the circuit board. Finally, the soldered circuit board wire is conveyed to the next process. The frame integrates wire loading, circuit board feeding, and soldering devices, automatically completing wire feeding, insulation removal and stripping, circuit board feeding, and circuit board soldering through continuous conveyor belt transport. The entire process requires no additional transfer of wires or circuit boards, reducing manual operations and improving soldering efficiency and precision. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0054] In one embodiment of the wire welding equipment of this utility model, please refer to... Figures 1 to 15The wire welding equipment includes a frame 100, a wire feeding device 200, a circuit board feeding device 300, and a welding device 400. The wire feeding device 200 is located on one side of the frame 100 and includes a circulating feeding mechanism 210, a wire cutting mechanism 220, a wire cutting mechanism 230, and a wire stripping mechanism 240. The circulating feeding mechanism 210 includes a conveyor belt 211 and multiple wire clamping stations 212 spaced apart on the conveyor belt 211. The wire cutting mechanism 220, the wire cutting mechanism 230, and the wire stripping mechanism 240 are arranged sequentially along the wire conveying direction and are located on the same side of the conveyor belt 211. The circuit board feeding device 300 is located on the other side of the frame 100 and includes a circuit board loading mechanism 310, a circuit board transfer mechanism 320, and a circuit board limiting mechanism 330. The circuit board transfer mechanism 320 is used to transfer the circuit board 600 from the circuit board loading mechanism 310 to the circuit board limiting mechanism 330. The circuit board limiting mechanism 330 is located next to the wire clamping station 212 at the end of the conveyor belt 100 and is used to limit the circuit board 600 and form a welding station. The welding device 400 is located above the welding station and is used to weld the wires of the wire clamping station 212 to the circuit board 600.

[0055] Specifically, the wire is first loaded into the clamping station 212. The clamping station 212 is conveyed by the conveyor belt 211, passing sequentially through the cutting mechanism 220, the insulation cutting mechanism 230, and the stripping mechanism 240. When the wire at the clamping station 212 passes through the cutting mechanism 220, the wire is cut to form a flat end face. The wire then moves with the clamping station 212 to the insulation cutting mechanism 230, where the outer insulation of the wire's front end is cut. Subsequently, the wire passes through the stripping mechanism 240, where the cut insulation is peeled off, exposing the wire core completely. Simultaneously, the circuit board transfer mechanism 320 removes the circuit board 600 from the circuit board loading mechanism 310 and places it on the circuit board limiting mechanism 330. Next, the exposed wire core is conveyed by the conveyor belt 211 to the soldering station of the circuit board limiting mechanism 330. The soldering device 400 precisely solders the wire core to the corresponding solder points on the circuit board 600. Finally, the soldered circuit board wire is conveyed to the next process. The frame integrates wire feeding, circuit board feeding, and welding devices. Through continuous conveying by conveyor belt 211, it automatically completes wire feeding, insulation stripping, circuit board feeding, and circuit board welding. The entire process requires no additional transfer of wires or circuit boards 600, reducing manual operation and improving welding efficiency and accuracy.

[0056] Preferably, please refer to Figure 1 and Figure 2 The conveyor belt 211 is a sprocket and chain drive assembly. On the other side of the conveyor belt 211 away from the wire cutting mechanism 220, there is a platform 219, which is used to support the wire located outside the wire clamping station 212.

[0057] For further details, please refer to... Figure 3The wire clamping station 212 includes a positioning seat 213 and a wire separating plate 215. The positioning seat 213 has a positioning cavity 214 with an open top. The cavity of the positioning cavity 214 extends through the positioning seat 213 perpendicular to the wire conveying direction. The wire separating plate 215 is located on the side of the positioning seat 213 near the wire cutting mechanism 220 and forms a gap 217 with the side wall of the positioning cavity 214. The top of the wire separating plate 215 has at least one downwardly recessed wire separating groove 216. The wire separating groove 216 extends through the wire separating plate 215 perpendicular to the wire conveying direction and is aligned with the position of the positioning cavity 214.

[0058] Specifically, the number of wire distribution slots 216 corresponds to the number of solder joints on the circuit board 600 (e.g., four). The wire is precisely inserted into the positioning cavity 214, with its front end extending beyond the front of the wire distribution plate 215. The exposed wire cores, after the insulation is stripped by the stripping mechanism 240, are guided into their respective wire distribution slots 216. The wire continues to move to the welding station via the conveyor belt 211. At this point, the wire cores located in the four wire distribution slots 216 form a precise one-to-one correspondence with the solder joints on the circuit board 600, and are finally welded and fixed by the welding device 400. The wire distribution plate 215 physically separates the multiple strands (e.g., four strands) of exposed wire cores after stripping and precisely guides them into their respective independent wire distribution slots 216, preventing the wire cores from becoming misaligned due to vibration or movement. This ensures that when the wire clamping station 212 arrives at the welding station with the wire, the position of the wire cores is aligned with the corresponding solder joints on the circuit board 600. The welding device 400 only needs to operate at a preset position, greatly simplifying the difficulty of welding positioning and improving welding accuracy and efficiency.

[0059] Preferably, the positioning seat 213 is further provided with through slots 218 that intersect the positioning cavity 214 in a cross shape. A support plate 2111 is provided above the conveyor belt 211, and vertical positioning plates 2112 are spaced apart below it. The bottom ends of the vertical positioning plates 2112 extend downwards and sequentially enter the through slots 218 corresponding to the multiple wire clamping stations 212 above the conveyor belt 211. Specifically, the wire is clamped in the positioning cavity 214 and moves with the conveyor belt 211. When the wire passes the vertical positioning plate 2112, the bottom end of the vertical positioning plate 2112 extends into the through slot 218 and continuously and stably presses against the wire, ensuring that the wire in the positioning cavity 214 remains firmly clamped during the conveying process. Therefore, even in subsequent stress processes such as cutting and stripping, the wire will not loosen or shift.

[0060] For further details, please refer to... Figure 4The wire cutting mechanism 220 includes a fixed base 221, a first lifting member 222, a first moving plate 223, a first lifting member 224, a second moving plate 225, and a cutter 226. The fixed base 221 is mounted on the frame 100. The first lifting member 222 is mounted on the top of the fixed base 221, and its output end is connected to the first moving plate 223. The first lifting member 224 is mounted on the bottom of the fixed base 221, and its output end is connected to the second moving plate 225, so that the first moving plate 223 and the second moving plate 225 are arranged vertically opposite each other. The cutter 226 is fixedly connected to the end of the first moving plate 223 near the wire clamping station 212.

[0061] Specifically, the wire enters between the cutter 226 and the second moving plate 225 via the conveyor belt 211. Subsequently, the first lifting member 222 drives the first moving plate 223 to move the cutter 226 downward, while the first lifting member 224 drives the second moving plate 225 upward. When the cutter 226 comes into contact with the second moving plate 225, the front end of the wire is cut off, and then the first lifting member 222 and the first lifting member 224 move back to their original positions.

[0062] For further details, please refer to... Figure 4 The cutting mechanism 230 includes a first cutting blade 231 and a second cutting blade 232. The first cutting blade 231 is located at the end of the first moving plate 223 near the wire clamping station 212, and the second cutting blade 232 is located at the end of the second moving plate 225 near the wire clamping station 212. The first cutting blade 231 and the cutter 226 are spaced apart and staggered front and back. The cutting edges of the first cutting blade 231 and the second cutting blade 232 are arranged vertically opposite each other, and limiting blocks 233 are provided on both sides of the first cutting blade 231 and the second cutting blade 232 to constrain the wire during cutting.

[0063] Specifically, the axial distance between the first cutting blade 231 and the wire clamping station 212 is less than the axial distance between the cutter 226 and the wire clamping station 212. After the front end of the wire is cut flat by the wire cutting mechanism 220, it moves to the insulation cutting station with the conveyor belt 211 and is precisely positioned between the first cutting blade 231 and the second cutting blade 232. Then, the first lifting member 222 drives the first moving plate 223 to move the first cutting blade 231 downward, while the first lifting member 224 drives the second moving plate 225 to move the second cutting blade 232 upward. The first cutting blade 231 and the second cutting blade 232 simultaneously cut the upper and lower insulation layers on the outside of the wire, exposing the wire core. The limit blocks 233 on both sides constrain the displacement of the wire during the cutting process to ensure the cutting accuracy. After the cutting is completed, the first lifting member 222 and the first lifting member 224 drive the moving plate to reset. The wire cutting mechanism 220 and the insulation cutting mechanism 230 share the first lifting component 222, the first lifting component 224 and the first / second moving plate, which simplifies the corresponding drive structure, reduces hardware costs while ensuring cutting positioning accuracy, and can simultaneously perform wire cutting and insulation cutting operations at two adjacent wire clamping stations 212, thereby improving efficiency.

[0064] Preferably, please refer to Figure 5 The fixed base 221 has a through-hole 2211 and a second through-hole 2212 on its side wall, which are not connected to each other. A first moving plate 223 has a first extension 2231 extending into the first through-hole 2211, and a second moving plate 225 has a second extension 2251 extending into the second through-hole 2212. A first lifting member 222 drives the first moving plate 223, causing the first extension 2231 to move vertically within the first through-hole 2211. A first lifting member 224 drives the second moving plate 225, causing the second extension 2251 to move vertically within the second through-hole 2212. Furthermore, a guide rod 2213 is provided inside the fixed base 221. The top and bottom ends of the guide rod 2213 are fixed to the top and bottom of the fixed base 221, respectively, and the guide rod 2213 is slidably connected to both the first moving plate 223 and the second moving plate 225.

[0065] Specifically, the first lifting member 222 and the first raising member 224 respectively drive the first moving plate 223 and the second moving plate 225 to move vertically along the guide rod 2213, causing their corresponding extensions to move synchronously in the first through groove 2211 and the second through groove 2212. The structure of the guide rod 2213 effectively ensures the accuracy of the vertical movement of the first / second moving plates, thereby ensuring the cutting accuracy of the tangent mechanism 220 and the skin cutting mechanism 230.

[0066] For further details, please refer to... Figure 6 The peeling mechanism 240 includes a slide rail 241, a mounting base 242, a second lifting member 243, a second lifting member 244, a first movable plate 245, a second movable plate 246, a first scraper 247, and a second scraper 248. The slide rail 241 is mounted on the frame 100 and is perpendicular to the conveyor belt 211. The mounting base 242 is slidably connected to the slide rail 241 via a first translation member 249. The second lifting member 243 is located at the top of the mounting base 242, and its output end is connected to the first movable plate 245. The second lifting member 244 is located at the bottom of the mounting base 242, and its output end is connected to the second movable plate 246. The first movable plate 245 and the second movable plate 246 are arranged vertically opposite each other. The first scraper 247 and the second scraper 248 are respectively located on the side of the first movable plate 245 and the second movable plate 246 near the clamping station 212.

[0067] Specifically, when the wire with the insulation layer to be cut moves to the stripping station, the second lifting component 243 drives the first movable plate 245 to move downwards, causing the first scraper 247 to move downwards; simultaneously, the second lifting component 244 drives the second movable plate 246 to move upwards, causing the second scraper 248 to move upwards. The two scrapers extend into the upper and lower cuts of the insulation layer, respectively. Subsequently, the first translation component 249 drives the mounting base 242 to move horizontally along the slide rail away from the conveyor belt. This translation action causes the first and second scrapers to clamp and translate the cut insulation layer, achieving complete separation of the insulation layer from the front end of the wire core. Finally, the front end of the wire core is fully exposed.

[0068] Preferably, please refer to Figure 7 There is a gap between the wire cutting mechanism 220, the peeling mechanism 230, the peeling mechanism 240 and the conveyor belt 211. The frame 100 is provided with a waste input hopper 110 in this gap. The bottom of the frame 100 is provided with a waste recycling box 120 that communicates with the material input hopper 110. The bottom of the fixed seat 221 of the wire cutting mechanism is slidably connected to the guide rail 227. The end of the guide rail 227 away from the conveyor belt is provided with a telescopic member 228. The output end of the telescopic member 228 is connected to the fixed seat 221.

[0069] Specifically, after the wire cutting mechanism 220 and the insulation stripping mechanism 240 complete the wire cutting and insulation stripping respectively, the resulting waste wire and waste insulation fall onto the second moving plate 225 and the second movable plate 246 respectively. Subsequently, the telescopic component 228 drives the fixed base 221 and the first translation component 249 drive the mounting base 242 to move towards the waste input hopper 110, pushing the waste to fall from the waste input hopper 110 into the waste recycling bin 120, thus achieving automated recycling. The second movable plate 246 has a through-hole on the side near the second scraper 248, allowing the waste insulation to fall directly into the waste recycling bin 120 through the through-hole.

[0070] For further details, please refer to... Figure 7 and Figure 8A pressing mechanism 250 is also provided on one side of the peeling mechanism 240. The pressing mechanism 250 is located directly above the conveyor belt 211 and includes a third lifting member 251 and a pressing block 252. The output end of the third lifting member 251 is connected to the pressing block 252 and is used to drive the pressing block 252 to move down and press the wire so that it is flat and positioned in the wire clamping station 212. Specifically, the third lifting member 251 is provided on the support plate 2111, and its output end extends out of the bottom of the support plate 2111 and connects to the pressing block 252. When the wire positioned at the clamping station 212 moves directly below the pressing mechanism 250, the front end of the wire reaches the stripping station. As the stripping mechanism 240 peels off the insulation layer to expose the wire core, the third lifting component 251 of the lowering mechanism drives the pressure block 252 to press down, compressing the wire located in the positioning cavity 214 and the gap 217. This action forces the exposed wire core to move downwards and precisely embed into the corresponding wire slot 216, ensuring that all wire cores in different wire slots are at the same horizontal height. Subsequently, the wire smoothly enters the next welding station along the conveyor belt 211. Preferably, the vertical cross-section of the pressure block 252 is U-shaped to avoid the vertical positioning plate.

[0071] For further details, please refer to... Figure 9 The circuit board transfer mechanism 320 includes a support base 324, a second translation member 321, a fourth lifting member 322, and an adsorption member 323. The support base 324 is fixedly mounted on the frame 100. The fourth lifting member 322 is mounted on the support base 324 and connected to the second translation member 321. The output end of the second translation member 321 extends towards the conveyor belt 211, and its output end is connected to the adsorption member 323. The adsorption member 323 is used to adsorb the circuit board 600. The circuit board limiting mechanism 330 includes a third translation member 331 and a limiting member 332. The third translation member 331 is fixedly mounted on the frame 100, and its output end is connected to the limiting member 332. The limiting member 332 has a limiting cavity 333 with a top opening and extending through the front and rear along the conveying direction. The opening of the limiting cavity 333 faces the wire clamping station 212. The third translation member 331 is used to drive the limiting member 332 to reciprocate between the conveyor belt 211 and the circuit board loading mechanism 310.

[0072] Specifically, the third translation member 331 of the circuit board positioning mechanism drives the positioning member 332 to move horizontally away from the conveyor belt 211, so that its positioning cavity 333 moves out of the welding device 400. Subsequently, the fourth lifting member 322 of the circuit board transfer mechanism drives the second translation member 321 to slide down on the support base 324, causing the adsorption member 323 to move down, so that it adsorbs the circuit board 600 provided by the circuit board loading mechanism 310; the fourth lifting member 322 moves up to reset; the second translation member 321 moves horizontally towards the positioning member 332; the fourth lifting member 322 drives the second translation member 321 to move down again, accurately placing the circuit board 600 held by the adsorption member 323 into the positioning cavity 333 of the positioning member; the third translation member 331 drives the positioning member 332 to move horizontally towards the conveyor belt 211, so that the circuit board 600 in the positioning cavity 333 is positioned directly below the welding device 400.

[0073] For further details, please refer to... Figures 9 to 11 The welding device 400 includes a welding head 410, a fifth lifting member 411, and a solder bar conveying assembly 420. The fifth lifting member 411 is located above the welding station and is connected to the welding head 410 so that the welding head 410 faces the welding station. The solder bar conveying assembly 420 is located on the frame 100 and is located on one side of the end of the conveyor belt 211. It is used to convey solder bars between the welding head 410 and the welding station.

[0074] Specifically, when the limiting cavity 333 of the circuit board limiting mechanism carries the circuit board 600 back to the welding station, and the exposed wire core of the wire positioned at the wire clamping station 212 also arrives at the welding station simultaneously, the solder bar conveying assembly 420 conveys the solder bar 421 between the welding head 410 and the circuit board 600, so that the free end of the solder bar 421 is suspended above the welding point; the fifth lifting component 411 drives the welding head 410 to move down, and the welding head 410 first presses down on the solder bar 421, and its high temperature melts the solder bar 421; the welding head 410 continues to move down, and the molten solder contacts and covers the multi-strand wire core separated by the wire divider 216, so that the wire core and the welding point of the circuit board 600 form a reliable connection. The addition of the solder bar 421 during the welding process significantly improves the welding success rate; shortens the pressure time of the welding head 410; reduces the contact time between the high temperature of the welding head 410 and the circuit board 600, reducing the risk of heat damage; and improves the overall welding efficiency.

[0075] Furthermore, the welding apparatus 400h also includes a fourth translation member 412, an L-shaped seat 413, a fifth translation member 414, and a slider 415. The fifth lifting member 411 is installed on the side of the support base 324 away from the second translation member 321. The output end of the fifth lifting member 411 is connected to the fourth translation member 412, and the output end of the fourth translation member 412 is connected to the L-shaped seat 413, for driving the L-shaped seat 413 to move horizontally on the support base 324 toward the conveyor belt 211. The fifth translation member 414 and the slider 415 are installed on the L-shaped seat 413. The output end of the fifth translation member 414 is connected to the slider 415, and a welding head 410 is installed on the slider 415, so that the welding head 410 is facing the welding station. The driving direction of the fifth translation member 411 is perpendicular to the driving direction of the fourth translation member 412.

[0076] Specifically, the fifth lifting component 411 shares a support base 324 with the circuit board transfer mechanism 320, reducing the area occupied by the equipment. Through the coordinated action of the fourth translation component 412, the fifth translation component 415 and the fifth lifting component 411, the welding head 410 can be precisely adjusted to any position in the vertical direction and horizontal plane, ensuring the precise alignment of the welding head 410 and the solder joint of the circuit board 600 in three-dimensional space.

[0077] Furthermore, please refer to Figure 11 and Figure 13 When the exposed core of the wire positioned at the wire clamping station 212 reaches the welding station, the support plate 2111 above the wire clamping station 212 is equipped with a sixth lifting member 261. The output end of the sixth lifting member 261 extends downward through the support plate 2111 and is connected to a wire clamping plate 260. The bottom end of the wire clamping plate 260 is provided with at least one downward-opening wire clamping groove 262. The wire clamping plate 260 is located between the welding station and the wire separating plate 215. The wire clamping groove 262 and the wire separating groove 216 correspond one-to-one and jointly constrain the vertical position of the multi-strand core. The solder bar conveying assembly 420 includes a mounting box 422, a rotary drive, a pair of vertically opposed bevel gears 423, a drive gear 424, and a driven gear 425. The tooth profile of one bevel gear 423 is V-shaped. The rotary drive is fixed inside the mounting box 422, and its output shaft extends out of the mounting box 422. It connects the drive gear 424 and one of the bevel gears 423. The drive gear 424 meshes with the driven gear 425, and the driven gear 425 drives the other bevel gear 423 through a connecting shaft. A guide groove 426 is provided next to the soldering station. The solder bar 421 is conveyed by the vertically opposed bevel gears 423 and guided to the solder joint of the circuit board 600 through the guide groove 426.

[0078] Specifically, the rotary drive unit drives the driving gear 424 and its coaxial bevel gear 423 to rotate, which in turn drives the meshing driven gear 425 and another bevel gear 423 to rotate in the opposite direction. The meshing bevel gears 423 clamp and drive the solder bar 421, breaking its surface. The solder bar 421 then passes through the guide groove 426 and is precisely delivered between the solder joint of the circuit board 600 and the solder head 410, so that the solder head 410 can melt the solder bar 421 more quickly.

[0079] During the welding process, the sixth lifting component 261 drives the wire clamping plate 260 to move downward. The wire clamping groove 262 presses against the multi-strand wire core located in the wire distribution groove 216, forcing it to move downward and reliably contact the solder joints of the circuit board 600. At this time, the wire distribution groove 216 and the wire clamping groove 262 work together to achieve bidirectional vertical positioning of the multi-strand wire core.

[0080] For further details, please refer to... Figure 12 The welding device 400 also includes a recycling component 430, which includes a recycling tube 431, a moving clamp 434, a sixth translation component 435, and a negative pressure component. The sixth translation component 435 is mounted on the frame 100 and its output end is connected to the moving clamp 434. The moving clamp 434 is used to clamp the outer periphery of the recycling tube 431. One end of the recycling tube 431 is provided with a through hole 432, which is close to the side of the welding head 410 and has a U-shaped notch 433 at the top for scraping the solder dross on the outer periphery of the welding head 410. The other end of the recycling tube 431 is connected to the negative pressure component.

[0081] Specifically, the negative pressure component is connected to the recovery pipe 431, continuously providing negative pressure to the through hole 432 on the side of the recovery pipe 431 facing the welding head 410, thereby adsorbing the waste gas generated during the welding process in real time. After the welding head 410 completes welding and resets, residual solder dross often adheres to its outer circumference. At this time, the sixth translation component 435 drives the moving clamp 434 to approach the welding head 410. The moving clamp 434 moves the recovery pipe 431 so that its U-shaped notch 433 scrapes against the surface of the welding head 410, causing the solder dross to peel off and fall into the recovery pipe 431, where it is then adsorbed and recovered by the negative pressure. This recovery component 430 automatically cleans the welding head 410, effectively ensuring the welding quality and precision of the welding head 410.

[0082] For further details, please refer to... Figure 14 and Figure 15 At the bend at the end of the conveyor belt 211, a stripping assembly 500 is also provided. The stripping assembly 500 includes a cantilever 510, which is arc-shaped. Its top end extends into the gap 217 between the wire separating plate 215 and the positioning cavity 214 to lift the welded wire. Its bottom end extends away from the bend of the conveyor belt 211 to guide the wire to slide onto the frame 100.

[0083] Specifically, after welding is completed, the circuit board limiting mechanism 330 moves away from the conveyor belt 211. Because the wire is securely clamped at the wire clamping station 212, the circuit board 600 is reliably separated from the limiting cavity 333. The welded circuit board 600 and the wire move towards the end of the conveyor belt 211. At this time, one end of the cantilever 510 extends into the gap 217 at the wire clamping station 212. As the conveyor belt 211 continues to run, the cantilever 510 periodically lifts the wire. When the wire is completely detached from the clamping station 212, guided by the cantilever 510, the wire slides down the cantilever 510 to the collection area of ​​the frame 100.

[0084] Preferably, the cantilever 510 has an arc-shaped piece 511 on the side facing away from the conveyor belt 211. The top end of the cantilever 510 extends beyond the top end of the arc-shaped piece 511, and a guide notch 512 is formed between the cantilever 510 and the arc-shaped piece 511. The bottom end of the arc-shaped piece 511 is fixed to the side of the conveyor belt 211, and the opening end of the guide notch 512 faces the welding station to avoid the wire divider 215. The arc-shaped piece 511 is used to carry and guide the welded circuit board 600 to slide down to the frame 100.

[0085] Specifically, when the cantilever 510 extends into the gap 217 under the wire and lifts the wire, the wire and the clamping station 212 move towards the bend along the conveyor belt 211; during the movement, the wire splitting plate 215 of the clamping station passes through the guide notch 512 to avoid interference with the arc-shaped plate 511; after the cantilever 510 lifts the wire away from the clamping station 212, the wire and the circuit board 600 connected to it slide down onto the frame 100 along the guide surface formed by the arc-shaped plate 511 and the cantilever 510.

[0086] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
