Description

Technical Field

[0001] This invention relates to the field of copper busbar soldering technology, and more specifically, to a soldering device for copper busbars. Background Technology

[0002] Because copper is an excellent conductor with very good electrical conductivity, copper busbars are commonly used as conductive connectors. Terminals are soldered onto the copper busbars to facilitate connections with other components. Currently, before soldering the terminals, a tin sheet is usually placed between the copper busbar and the terminals. Soldering is typically performed using soldering equipment. During heating, the tin sheet melts between the copper busbar and the terminals. The main advantages of placing a tin sheet between the copper and the connecting terminals include improved solderability and enhanced oxidation resistance. Firstly, improved solderability is a significant benefit of soldering copper plates. Tin has a low melting point and good fluidity, allowing it to fill the tiny gaps on the copper plate surface, increasing the contact area and thus improving solderability. Furthermore, improved conductivity is another important advantage of soldering copper plates. Although tin's conductivity is not as high as copper's, with proper design and process control, a suitable tin layer can be formed on the copper plate surface, preventing oxidation while maintaining a certain level of conductivity. Especially at high temperatures, the conductivity of the tin layer increases with rising temperature.

[0003] Regarding the aforementioned technologies, the inventor believes that while current soldering equipment can solder copper busbars and terminals, the copper busbars typically have multiple terminals arranged in a straight line at equal intervals, requiring continuous soldering. In practice, most soldering equipment requires continuous manual operation to place the copper busbars, terminals, and solder sheets, gradually soldering multiple terminals – a very slow process. A smaller number of soldering devices are CNC-controlled, allowing for continuous, equidistant soldering of multiple terminals. However, the spacing between terminals varies across different copper busbars, and this type of equipment requires CNC adjustment. Most operators cannot master the adjustment operation of CNC soldering equipment, making it inconvenient for workers. Furthermore, such equipment is expensive. Therefore, considering these problems, widespread use of such equipment is not feasible. To address this, a soldering device for copper busbars is proposed. Summary of the Invention

[0020] The following is in conjunction with the appendix Figure 1-9 The present invention will be described in further detail below.

[0021] Please see Figure 1-9 A soldering device for copper busbars includes a main module 100 and a continuous soldering module 200. The main module 100 includes a solder rack 110, a device frame 120 fixedly connected to the top of the solder rack 110, a cylinder 130 mounted on the device frame 120, and a soldering device body 140 fixedly connected to the output shaft of the cylinder 130. An elongated displacement groove 150 is formed on the top of the solder rack 110. The continuous soldering module 200 includes a movable stage 210 slidably connected inside the elongated displacement groove 150, a fixing component 220 mounted on the top of the movable stage 210, and a main rotating rod 230 rotatably connected to the rear end face of the inner wall of the solder rack 110. A one-way movable component 240 is provided between one end and the rear end face. An adjustment drive component 250 is provided on the rear end face of the solder frame 110. The adjustment drive component 250 is connected to the one-way movable component 240. A connecting component 260 is provided between the other end of the main rotating rod 230 and the top of the inner wall of the solder frame 110. A rack 270 is fixedly connected to the bottom of the moving stage 210 near the rear end face of the solder frame 110. The connecting component 260 is connected to the rack 270. A locking component 280 is provided between the main body 140 of the soldering device and the top of the moving stage 210. A resistance component 290 is provided between the rear end face of the solder frame 110 and the outer surface of the main rotating rod 230.

[0022] In use, the copper busbars to be soldered are placed on top of the moving stage 210, and the terminals and solder sheets are arranged accordingly. They are then secured using the fixing component 220. Subsequently, the operator manipulates and adjusts the drive component 250 according to the spacing between the terminals. Opening the drive component 250 causes it to swing downwards, which in turn drives the main rotating rod 230 via the one-way moving component 240. The main rotating rod 230 then drives the connecting component 260 to drive the rack 270, causing the rack 270 to move the moving stage 210 a certain distance within the elongated displacement groove 150. The subsequent upward swing of the adjustment drive component 250 will drive the unidirectional moving component 240 to idle. At this time, the cylinder 130 drives the soldering device body 140 to descend, thereby achieving soldering connection of the copper busbar and terminals. Afterward, the cylinder 130 lifts the soldering device body 140, and the adjustment drive component 250 swings downward again. At this time, the adjustment drive component 250 will again achieve the transmission displacement of the moving stage 210. Subsequently, the soldering device body 140 descends again to complete the continuous soldering operation. This equipment can realize continuous soldering operation and makes the spacing adjustment more convenient.

[0023] The one-way movable component 240 includes a rotating wheel 241 rotatably connected to the rear end of the main rotating rod 230. A hollow gear 242 is rotatably connected to the rear end face of the solder frame 110. A ratchet groove 245 is formed on the inner wall of the hollow gear 242.

Multiple elastic plates 244 are fixedly connected to the rear end face of the rotating wheel 241. The outer surfaces of the multiple elastic plates 244 contact the outer surfaces of the multiple thrust ratchet teeth 243. The one-way movable component 240 also includes a large gear disk 246 rotatably connected to the rear end face of the solder frame 110. A linkage gear 247 is fixedly connected to the rear end face of the 46. The outer surface of the large gear disk 246 meshes with the outer surface of the hollow gear 242. The adjustment drive assembly 250 includes an incomplete gear 251 rotatably connected to the rear end face of the solder frame 110. The outer surface of the incomplete gear 251 meshes with the outer surface of the linkage gear 247. A swing arm 252 is fixedly connected to the rear end face of the incomplete gear 251. A strip groove 253 is provided inside the swing arm 252. The adjustment drive assembly 250 also includes a drive motor 254 fixedly connected to the rear end face of the inner wall of the solder frame 110. The output shaft of the drive motor 254 extends to the rear end face of the solder frame 110 and is fixedly connected to a drive disk 255. A sliding groove is provided on the rear end face of the drive disk 255. An adjusting screw 256 is rotatably connected between the top and bottom of the wall. One end of the adjusting screw 256 extends to the outside of the drive disc 255. A moving block 257 is slidably connected inside the slide groove. The inside of the moving block 257 is threadedly connected to the outer surface of the adjusting screw 256. A pointer 259 is fixedly connected to the outer surface of the moving block 257. The rear end face of the drive disc 255 has multiple spacing indicator slots 258 evenly spaced in a straight line. The pointer 259 is located directly in front of one of the spacing indicator slots 258. A drive shaft 2510 is fixedly connected to the front end face of the moving block 257. The drive shaft 2510 is movably connected inside the strip groove 253. The connecting assembly 260 includes a hexagonal slot formed on the front end face of the main rotating rod 230. The inner surface of the hexagonal slot... A hexagonal rod 262 is movably connected to the soldering device. A fixing spring 263 is fixedly connected between one end of the hexagonal rod 262 and the inner wall of the hexagonal slot. A connecting gear 264 is fixedly connected to the front end face of the hexagonal rod 262. The connecting gear 264 meshes with the rack 270. Two mounting seats 261 are fixedly connected to the top of the inner wall of the soldering device 110. One mounting seat 261 is rotatably sleeved on the outer surface of the main rotating rod 230. A pressure rod 265 is movably connected inside the other mounting seat 261. One end of the pressure rod 265 is fixedly connected to the front end face of the connecting gear 264. The locking assembly 280 includes two mounting plates 281 fixedly connected to the main body 140 of the soldering device. A locking rod 282 is fixedly connected to the bottom of each mounting plate 281.Multiple locking holes 283 are provided on the top of the mobile platform 210 near both the front and rear faces, and each locking hole 283 is adapted to a locking rod 282.

[0024] When the drive motor 254 is turned on, the drive disk 255 rotates. The drive disk 255 drives the transmission shaft 2510 to move inside the strip groove 253. The transmission shaft 2510 pushes the swing arm 252, which in turn drives the incomplete gear 251 to swing upward. The strip groove 253 then drives the large gear disk 246 through the linkage gear 247. The large gear disk 246 drives the hollow gear 242. The hollow gear 242 drives the thrust ratchet 243 through the ratchet groove 245. The thrust ratchet 243 drives the rotating wheel 241, thereby driving the main rotating rod 230 to rotate. When the rotating rod 230 rotates, it will drive the connecting gear 264 to rotate via the hexagonal rod 262. The connecting gear 264 drives the rack 270, causing the rack 270 to drive the moving table 210 to slide a certain distance inside the long displacement groove 150. Subsequently, the incomplete gear 251 will be driven to swing downwards. When the incomplete gear 251 swings downwards, the large gear disk 246 will drive the hollow gear 242 to rotate freely on the outer surface of the rotating wheel 241, so that the connecting gear 264 will not drive the moving table 210 to move. At this time, the cylinder 130 drives the soldering device body 140 to descend, and the soldering... When the main body 140 of the device descends, the locking rod 282 will insert into the locking hole 283 to lock the moving stage 210, thereby making the soldering connection of the main body 140 of the soldering device to the copper busbar and terminals more stable. Then, the cylinder 130 lifts the main body 140 of the soldering device, and the incomplete gear 251 swings downward again, thereby realizing the transmission displacement of the moving stage 210 again. When it is necessary to adjust the displacement distance of the moving stage 210 according to the terminal spacing, the pressure rod 265 is pushed. The pressure rod 265 will drive the connecting gear 264 and the hexagonal rod 262 to move. At this time, the fixing spring 26 3. The compression and connection gear 264 are disconnected from the rack 270. Then, the adjusting screw 256 is rotated according to the spacing between multiple terminals. The adjusting screw 256 will drive the moving block 257 and the transmission shaft 2510 to move downward. The transmission shaft 2510 knows the adjusted spacing value according to the cooperation of the pointer 259 and the spacing indicator slot 258. After the adjustment is completed, the pressure rod 265 is released, the connection gear 264 is reset and reconnected to the rack 270, thereby completing the adjustment of the solder spacing. This allows the equipment to achieve continuous soldering operation and makes the spacing adjustment more convenient.

[0025] The resistance assembly 290 includes an inner hollow slot plate 291 fixedly connected to the rear end face of the inner wall of the solder rack 110. A lifting block 292 is slidably connected inside the inner hollow slot plate 291. A pressure spring 295 is fixedly connected to the top of the lifting block 292. A mounting screw 296 is threadedly connected to the bottom of the inner hollow slot plate 291. The top of the mounting screw 296 is rotatably connected to the bottom of the lifting block 292. A resistance block 293 is fixedly connected to the outer surface of the main rotating rod 230. A resistance arm 294 is slidably connected inside the inner hollow slot plate 291. The bottom of the resistance arm 294 is fixedly connected to the top of the pressure spring 295. The top of the resistance arm 294 is in contact with the outer surface of the resistance block 293.

[0026] When the main rotating rod 230 is working, the resistance arm 294 abuts against the outer surface of the resistance block 293 through the elastic force of the pressure spring 295, thereby increasing the resistance when the main rotating rod 230 rotates, thus preventing the main rotating rod 230 from rotating due to inertia and improving its stability. At the same time, the resistance can be adjusted by rotating the mounting screw 296 to compress the pressure spring 295, which is convenient for operators.

[0027] The fixing component 220 includes a hollow base 221 fixedly connected to the top of the moving platform 210. A T-shaped plate 223 is slidably connected inside the hollow base 221. A first screw 222 is rotatably connected between the bottom and top of the inner wall of the hollow base 221. The interior of the T-shaped plate 223 is threadedly connected to the outer surface of the first screw 222. Both ends of the outer surface of the T-shaped plate 223 are threadedly connected to second screws 224. An n-shaped plate 225 is provided below the T-shaped plate 223. The top of the n-shaped plate 225 is rotatably connected to the bottom ends of the two second screws 224. The fixing component 220 also includes a strip-shaped limiting groove 226 opened on the top of the moving platform 210. A pad 227 is movably connected inside the strip-shaped limiting groove 226. The top of the pad 227 is at the same height as the bottom of the n-shaped plate 225.

[0028] Replace the pad 227 according to the thickness of the copper busbar, so that the top of the pad 227 is on the same plane as the top of the copper busbar. Then, stack the terminals and solder sheets to be soldered between the top of the copper busbar and the pad 227. Then, rotate the first screw 222, which drives the T-plate 223 to descend. The descending T-plate 223 presses down on multiple terminals. Finally, rotate the two second screws 224 to drive the n-shaped plate 225 to descend. The n-shaped plate 225 presses down and fixes the copper busbar, making the subsequent soldering operation more stable.

[0029] The implementation principle of this invention is as follows: During use, the copper busbar is placed on top of the moving platform 210. Then, the pad 227 is replaced according to the thickness of the copper busbar, ensuring the top of the pad 227 is flush with the top of the copper busbar. The terminals to be soldered and solder sheets are then stacked between the copper busbar and the top of the pad 227. Next, the first screw 222 is rotated, causing the T-plate 223 to descend. The descending T-plate 223 presses down on multiple terminals. Finally, the two second screws 224 are rotated to descend the n-shaped plate 225, which presses and fixes the copper busbar, making subsequent soldering operations more stable. Then, the drive motor 254 is turned on to drive the drive disk 255 to rotate. The drive shaft 2510 moves within the slot 253, pushing the swing arm 252 to cause the incomplete gear 251 to swing upwards. The slot 253 then drives the large gear disk 246 via the linkage gear 247. The large gear disk 246 drives the hollow gear 242, which in turn drives the thrust ratchet 243 via the ratchet groove 245. The thrust ratchet 243 drives the rotating wheel 241, thereby rotating the main rotating rod 230. When the main rotating rod 230 rotates, it drives the connecting gear 264 via the hexagonal rod 262. The connecting gear 264 drives the rack 270, causing the rack 270 to drive the moving table 210 to slide a certain distance within the long displacement slot 150. The subsequent incomplete... Gear 251 will be driven to swing downwards. When the incomplete gear 251 swings downwards, the large gear disk 246 will drive the hollow gear 242 to rotate freely on the outer surface of the rotating wheel 241, so that the connecting gear 264 will not drive the moving stage 210 to move. At this time, the cylinder 130 drives the soldering device body 140 to descend. When the soldering device body 140 descends, the locking rod 282 will insert into the locking hole 283 to lock the moving stage 210, thereby making the subsequent soldering connection of the soldering device body 140 to the copper busbar and terminals more stable. Afterwards, the cylinder 130 lifts the soldering device body 140, and the incomplete gear 251 swings downwards again, thereby realizing the transmission displacement of the moving stage 210 again. Adjustments need to be made according to the terminal spacing. When the moving stage 210 moves a certain distance, the pressure rod 265 is pushed. The pressure rod 265 will drive the connecting gear 264 and the hexagonal rod 262 to move. At this time, the fixing spring 263 is compressed and the connecting gear 264 is disengaged from the rack 270. Then, the adjusting screw 256 is rotated according to the spacing between multiple terminals. The adjusting screw 256 will drive the moving block 257 and the transmission shaft 2510 to move downward. The transmission shaft 2510 knows the adjusted spacing value according to the cooperation of the pointer 259 and the spacing indicator slot 258. After the adjustment is completed, the pressure rod 265 is released, the connecting gear 264 resets and reconnects to the rack 270, thus completing the adjustment of the solder spacing. This allows the equipment to achieve continuous soldering operation and makes the spacing adjustment more convenient.Furthermore, this equipment has a lower cost compared to existing CNC soldering equipment, facilitating its widespread use in this field. When the main rotating rod 230 is working, the resistance arm 294, through the elastic force of the pressure spring 295, abuts against the outer surface of the resistance block 293, thereby increasing the resistance during the rotation of the main rotating rod 230. This prevents the main rotating rod 230 from rotating due to inertia, improving its stability.
