[0035] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0036] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0037] Please refer to Figures 1 to 25 , a battery top cover welding device, including a frame 5, a loading mechanism 3, a welding device 2, a transfer component 6, a rolling mechanism 7 and a post-welding detection component 4. Among them, the loading mechanism 3 is arranged on the frame 5 and is used for transporting the battery 1. The loading mechanism 3 includes a guide seat beam 31 and a loading component 32. The guide seat beam 31 extends along the second direction Y. The loading component 32 is arranged on the guide seat beam 31, and the loading component 32 can move along the second direction Y relative to the guide seat beam 31; there are two welding devices 2, and the two welding devices 2 are arranged at intervals along the second direction Y; the transfer component 6 is arranged between the two welding devices 2 and is used for flipping the battery 1 so that the positions of its two top covers are swapped; the rolling mechanism 7 is arranged on the frame 5 and is arranged opposite to the welding device 2 with respect to the guide seat beam 31; the post-welding detection component 4 is arranged on the frame 5, downstream of the rolling mechanism 7, and on the same side of the guide seat beam 31 as the rolling mechanism 7. As Figure 1 and Figure 2 shown, the guide seat beam 31 divides the frame 5 into two regions in the third direction Z. By cooperating with the guide seat beam 31, the loading component 32 transports the battery 1 along the second direction Y. In this way, by centrally arranging the loading mechanism 3, it can load and unload materials for the welding devices 2, the rolling mechanism 7 and the post-welding detection component 4 on both sides at the same time, improving the processing efficiency while effectively connecting the various mechanisms (welding device 2, rolling mechanism 7 and post-welding detection component 4) in the processing and transportation direction of the battery 1, and overcoming the problem of poor connection between the functional mechanisms.

[0038] As Figures 3 to 7As shown in the figure, the loading component 32 includes a transfer plate 321, an extension bracket 322, and a clamping member 323. The transfer plate 321 is installed on the guide beam 31. The clamping member 323 is installed on the transfer plate 321 through the extension bracket 322, and the clamping member 323 is installed at one end of the extension bracket 322 away from the transfer plate 321. The clamping member 323 can move relative to the transfer plate 321 in the first direction X, and the first direction X is perpendicular to the second direction Y. The clamping member 323 is used to clamp the battery 1. The clamping member 323 can move relative to the transfer plate 321 in the first direction X, thereby increasing the movement range of the battery 1 clamped by the clamping member 323 in the first direction X. This enables the loading mechanism 3 to adapt to more working conditions without interference. At the same time, the clamping member 323 is installed on the transfer plate 321 through the extension bracket 322, and the clamping member 323 is located at one end of the extension bracket 322 away from the transfer plate 321. This can increase the spatial distance between the clamping member 323 and the transfer plate 321, that is, the guide beam 31, which is beneficial to the loading and transfer of the battery 1, especially the blade battery, without interference, so that the loading mechanism 3 can adapt to the loading and transfer of more models of batteries 1.

[0039] Specifically, as Figure 3 shown in the figure, two loading components 32 are installed on the guide beam 31 through a linear module to realize the movement of the loading component 32 relative to the guide beam 31 in the second direction Y. The extension bracket 322 is movably connected to the transfer plate 321 through a linear module to realize the movement of the clamping member 323 relative to the transfer plate 321 in the first direction X.

[0040] As Figures 5 to 7 shown in the figure, the clamping member 323 includes a first top plate 3231 installed on the extension bracket 322. Two clamping portions 3232 are provided on the first top plate 3231, and the two clamping portions 3232 can approach or move away from each other to clamp or release the battery 1.

[0041] Further, the clamping portion 3232 includes a second top plate 32321 mounted on the first top plate 3231. An installation plate 32322 is provided on the second top plate 32321. The installation plate 32322 extends along the first direction X toward the side away from the first top plate 3231. An adjustment plate 32324 is provided on the installation plate 32322. The adjustment plate 32324 can move relative to the installation plate 32322 along the first direction X. A first elastic member 32323 is provided between the adjustment plate 32324 and the second top plate 32321. A clamping jaw 3233 is provided on the installation plate 32322. With such a setting, hard contact between the clamping jaw 3233 and the battery loading structure can be avoided during the process of the clamping jaw 3233 grasping the battery 1. Specifically, when the clamping jaw 3233 abuts against the battery loading structure along the first direction X, the battery loading structure acts on the clamping jaw 3233, and the adjustment plate 32324 moves upward along the first direction X relative to the installation plate 32322 to compress the first elastic member 32323, thereby achieving buffering.

[0042] Preferably, the first elastic member 32323 is a spring. A first guide rod (not shown in the figure) extending along the first direction X is provided on the second top plate 32321. A first guide hole (not shown in the figure) adapted to the first guide rod is provided on the adjustment plate 32324. The first guide rod is slidably embedded in the first guide hole, and the first elastic member 32323 is sleeved outside the first guide rod; or a first guide rod extending along the first direction X is provided on the adjustment plate 32324, and a first guide hole adapted to the first guide rod is provided on the second top plate 32321. The first guide rod is slidably embedded in the first guide hole, and the first elastic member 32323 is sleeved outside the first guide rod. The first guide rod here facilitates the assembly of the spring and is also beneficial to improving the stability of the movement of the adjustment plate 32324 relative to the installation plate 32322.

[0043] In this embodiment, the adjustment plate 32324 is slidably connected to the installation plate 32322 through a slide rail and slider assembly.

[0044] Further, as Figure 5 shown, a first limiting notch 3234 is configured on the adjustment plate 32324, and a limiting block 3235 is provided on the installation plate 32322. The limiting block 3235 at least partially extends into the first limiting notch 3234. The limiting block 3235 here is used to limit the extreme position of the adjustment plate 32324 in the first direction X, specifically to limit the extreme position of the adjustment plate 32324 downward along the first direction X.

[0045] As Figure 5 shown, the adjustment plate 32324 is located on the side of the installation plate 32322 away from the other clamping portion 3232. In this way, the space adjustment range between the two clamping portions 3232 can be increased, which is beneficial to adapting to the clamping of different models of batteries.

[0046] As Figure 6 shown, a pressing plate 3236 and a first driving member 3237 are provided on the adjusting plate 32324. The first driving member 3237 is used to drive the pressing plate 3236 to move relative to the adjusting plate 32324 along the first direction X; a second guiding hole (not shown in the figure) is provided on the adjusting plate 32324, and a second guiding rod 3238 adapted to the second guiding hole is provided on the pressing plate 3236. The second guiding rod 3238 is slidably embedded in the second guiding hole; the pressing plate 3236 is located on the side of the adjusting plate 32324 close to the other clamping portion 3232. Preferably, the first driving member 3237 includes, but is not limited to, a cylinder, a hydraulic cylinder or an electric push rod. In this embodiment, at least a part of the jaw 3233 is on the downward movement path of the pressing plate 3236 in the first direction X.

[0047] As Figure 5 and Figure 6 shown, the jaw 3233 is L-shaped. In use, the battery 1 is carried by the jaw 3233, and the pressing plate 3236 moves downward along the first direction X to cooperate with the jaw 3233 to press the battery 1 tightly, so as to ensure that the posture of the battery 1 is stable during the feeding process.

[0048] In order to prevent damage to the battery 1, an elastic protective sleeve 32331 is sleeved outside the jaw 3233. The elastic protective sleeve 32331 can be made of elastic silica gel or elastic rubber.

[0049] In this embodiment, on the same adjusting plate 32324, at least two jaws 3233 are provided, and at least two jaws 3233 are arranged at intervals along the third direction Z on the adjusting plate 32324. In this way, the battery 1 can be better clamped in the length direction of the battery 1. In this embodiment, the length direction of the battery 1 is parallel to the third direction Z.

[0050] As Figure 5 shown, the second top plate 32321 is slidably connected to the first top plate 3231, and a second driving member 3239 is provided on the first top plate 3231 for driving the second top plate 32321 to move relative to the first top plate 3231. Optionally, the second driving member 3239 is a cylinder.

[0051] In this embodiment, the clamping member 323 further includes an oil box 3230. The oil box 3230 passes through the mounting plate 32322 and is located below the second top plate 32321; the oil box 3230 is installed on the first top plate 3231 through a connecting rod. The oil box 3230 here can prevent the lubricating oil in the second driving member 3239 from contaminating the battery 1 carried below.

[0052] As Figure 1 and Figure 2As shown in the figure, feeding assemblies 32 can be arranged on both sides of the guide seat beam 31 in the third direction Z as required. At the same time, multiple feeding assemblies 32 can also be arranged at intervals along the second direction Y on the same side of the guide seat beam 31 in the third direction Z to handle the feeding and unloading operations of the welding device 2, the transfer assembly 6, the post-welding inspection assembly 4, etc.

[0053] Furthermore, as Figures 8 to 20 shown, the welding device 2 includes a base 20, a rotary fixture 22, a transfer assembly 24, a positioning mechanism 21, a welding mechanism 23 and an air-cooling assembly 25. Among them, the rotary fixture 22 is arranged on the base 20 and is used for clamping the battery 1; the transfer assembly 24 is arranged on one side of the rotary fixture 22 and is used for transferring the battery 1 to the rotary fixture 22; the positioning mechanism 21 is arranged on the other side of the rotary fixture 22 and is used to cooperate with the transfer assembly 24 to position the battery 1 in the rotary fixture 22; the welding mechanism 23 is arranged close to the positioning mechanism 21; the rotary fixture 22 includes a rotary platform, the outer ring 221 of the rotary platform is fixedly installed on the base 20, the inner ring 222 of the rotary platform is rotatably connected to the outer ring 221, a mover part is arranged on the inner ring 222, a receiving hole 220 for accommodating the battery 1 is arranged on the mover part, a pressing plate 226 for clamping the battery 1 is arranged on the mover part, at least part of the pressing plate 226 is internally provided with a first cooling air passage, a trachea mounting bracket 26 is arranged on the mover part, a first docking surface (not shown in the figure) is configured on the trachea mounting bracket 26, and a first air hole (not shown in the figure) is arranged on the first docking surface, and the first air hole communicates with the first cooling air passage; the air-cooling assembly 25 is arranged on one side of the rotary fixture 22 and includes a trachea push plate 252, an air-cooling joint 2521 corresponding to the first air hole is arranged on the trachea push plate 252, and the trachea push plate 252 can approach or move away from the first docking surface so that the air-cooling joint 2521 communicates with or disconnects the first air hole; the air-cooling joint 2521 communicates with a compressed air source (not shown in the figure). As Figure 8 and Figure 9 shown, the base 20 includes a bottom base 202 and a longitudinal base 201. The longitudinal base 201 is arranged on the bottom base 202. The rotary fixture 22 is installed on the longitudinal base 201. The positioning mechanism 21 and the air-cooling assembly 25 are arranged on the bottom base 202 on the same side of the longitudinal base 201. The transfer assembly 24 is arranged on the bottom base 202 on the other side of the longitudinal base 201. The welding mechanism 23 is arranged on the longitudinal base 201. In this embodiment, in order to improve the processing efficiency, six rotary fixtures 22 are arranged on the longitudinal base 201, so that the clamping and positioning of six batteries 1 can be carried out simultaneously. A first linear module 231 is arranged on the longitudinal base 201. Further, in order to improve the processing efficiency, two welding mechanisms 23 are assembled on the first linear module 231 to simultaneously complete the welding of the batteries 1 on two corresponding rotary fixtures 22. Of course, in other embodiments, the numbers of the welding mechanism 23 and the rotary fixture 22 can be specifically determined according to needs and are not limited to the scheme of this embodiment.

[0054] In use, first place the battery 1 on the transfer component 24. The transfer component 24 conveys the battery 1 to the rotary fixture 22. The transfer component 24 cooperates with the positioning mechanism 21 to position the battery 1 at the rotary fixture 22. Subsequently, the battery 1 is clamped and fixed to the rotary fixture 22 by the pressing plate 226. Next, the welding mechanism 23 welds the battery 1, specifically the top cover and the housing of the battery 1. The high temperature generated during the welding process will be transferred to the pressing plate 226. When the welding is completed, the rotary fixture 22 resets and releases the battery 1. The transfer component 24 unloads the welded battery 1 from the rotary fixture 22. Finally, the air pipe push plate 252 moves towards the first docking surface so that the air cooling joint 2521 connects to the first air hole, and the cooling gas in the compressed air source is conveyed into the first cooling air duct to cool the pressing plate 226, so as to ensure the function of the rotary fixture 22 and the processing quality of the battery 1. In this embodiment, as Figure 10 shown, a first air pipe joint 261 is provided on the air pipe mounting bracket 26, and a second air pipe joint 229 is provided on the pressing plate 226. The first air pipe joint 261 is installed at one end of the first air hole away from the air cooling component 25. The first air pipe joint 261 and the second air pipe joint 229 are connected by a guide air pipe (not shown in the figure). Here, by integrating multiple first air holes on the air pipe mounting bracket 26 to cooperate with the air cooling component 25, specifically the air pipe push plate 252, to achieve the rapid connection and disconnection of the compressed air source and the first cooling air duct, it can meet the air cooling requirement of the pressing plate 226 under the processing condition of the circumferential rotation of the rotary fixture 22, and at the same time avoid affecting the smooth operation of the welding device 2 due to the winding of the guide air pipe.

[0055] In this embodiment, an exhaust hole (not shown in the figure) is provided on the pressing plate 226 provided with the first cooling air duct. The exhaust hole is communicated with the first cooling air duct. After the compressed air enters the first cooling air duct, it escapes from the pressing plate 226 through the exhaust hole and takes away heat.

[0056] As Figure 10 shown, in this embodiment, the first docking surface is a plane. A second docking surface 2523 is provided on one side of the air pipe push plate 252 facing the first docking surface. In the position as Figure 10 shown, the first docking surface is parallel to the second docking surface 2523. Specifically, as Figure 10 shown, a second air hole (not shown in the figure) is provided through the air pipe push plate 252. The second air hole corresponds to the first air hole one by one. The air cooling joint 2521 is installed at one end of the second air hole away from the air pipe mounting bracket 26. A silica gel sleeve 2522 is provided at one end of the second air hole close to the air pipe mounting bracket 26. In this embodiment, a second telescopic member 251 is provided on the bottom table 202 to drive the air pipe push plate 252 to approach or move away from the air pipe mounting bracket 26, so that the second air hole is connected or disconnected from the first air hole. As Figure 10As shown, during use, after the welded battery 1 is unloaded, the second telescopic member 251 extends to drive the trachea push plate 252 mounted on the telescopic end of the second telescopic member 251 to move towards the trachea mounting bracket 26 until the silica gel sleeve 2522 abuts against the first docking surface to connect the second air hole and the first air hole. The silica gel sleeve 2522 is deformed under pressure so that the connection between the second air hole and the first air hole can be better sealed, greatly reducing the probability of air leakage at the connection between the second air hole and the first air hole.

[0057] As Figure 10 shown, the pressing plate 226 includes a first moving plate 2261 and a second moving plate 2262 that are movably connected to the mover part. The moving direction of the first moving plate 2261 relative to the mover part is perpendicular to the moving direction of the second moving plate 2262 relative to the mover part. A first fixed plate 2263 corresponding to the first moving plate 2261 and a second fixed plate 2264 corresponding to the second moving plate 2262 are provided on the mover part. The area formed by the limiting of the first moving plate 2261, the first fixed plate 2263, the second moving plate 2262, and the second fixed plate 2264 coincides with the accommodating hole 220. At least one of the first moving plate 2261, the first fixed plate 2263, the second moving plate 2262, and the second fixed plate 2264 is internally provided with a first cooling air duct. In this embodiment, the battery 1 is a blade battery. The first moving plate 2261 and the first fixed plate 2263 are on the long side of the top cover of the battery 1, and the second moving plate 2262 and the second fixed plate 2264 are on the short side of the top cover of the battery 1. Optionally, since the contact area between the first moving plate 2261 and the first fixed plate 2263 and the battery 1 is large and they are greatly affected by the heat transfer during battery 1 welding, a first cooling air duct is provided in the first moving plate 2261 and the first fixed plate 2263. In another embodiment, a second cooling air duct can also be provided in the second moving plate 2262 and the second fixed plate 2264. The first fixed plate 2263 and the second fixed plate 2264 here serve as positioning references, and cooperate with the first moving plate 2261 and the second moving plate 2262 to position the battery 1 in the first direction X and the second direction Y. The transfer assembly 24 cooperates with the positioning mechanism 21 to position the battery 1 in the third direction Z, thereby realizing the spatial positioning and clamping of the battery 1. In this embodiment, the second trachea joint 229 is provided on the first moving plate 2261 and the first fixed plate 2263 and is respectively connected to their respective first cooling air ducts.

[0058] As Figure 10As shown in the figure, the rotary fixture 22 further includes an unlocking portion 227 and an actuating portion 228. The first movable plate 2261 and the second movable plate 2262 are movably connected to the mover portion through the actuating portion 228. The unlocking portion 227 is used to cooperate with the actuating portion 228 to move the first movable plate 2261 away from the first fixed plate 2263 and the second movable plate 2262 away from the second fixed plate 2264 to unlock the battery 1. The actuating portion 228 is disposed on the mover portion, and the unlocking portion 227 is disposed on the outer ring 221 or the base 20 and is on the rotation path when the actuating portion 228 follows the mover portion to rotate. There are two unlocking portions 227 and actuating portions 228 respectively, which are correspondingly arranged with the first movable plate 2261 and the second movable plate 2262. When in the state as shown in Figure 10 , it is the state of loading and unloading the battery 1 at the rotary fixture 22. At this time, the unlocking portion 227 and the actuating portion 228 correspond, that is, the rotary fixture 22 is in the unlocked position. Preferably, the unlocking portion 227 is disposed on the base 20.

[0059] As shown in Figure 14 , the actuating portion 228 includes a first push plate 2281 slidably connected to the mover portion for assembling the first movable plate 2261 and the second movable plate 2262. The actuating portion 228 further includes a reset stop 2282 disposed on the mover portion. A reset member 2284 is disposed between the reset stop 2282 and the first push plate 2281. The reset member 2284 acts on the first push plate 2281 to make it have a movement tendency towards the center of the receiving hole 220. Preferably, the reset member 2284 is a spring, which is pressed between the reset stop 2282 and the first push plate 2281 to provide the first push plate 2281 with a movement tendency towards the center of the receiving hole 220, thereby driving the first pressing plate 226 to move towards the first fixed plate 2263 and at the same time driving the second movable plate 2262 to move towards the second fixed plate 2264 to realize flexible clamping of the battery 1, avoid pressing damage to the battery 1, and at the same time be able to adapt to clamping of different models of the battery 1.

[0060] In this embodiment, in order to facilitate the assembly of the spring, a stabilizing rod 2283 is penetrated through the reset stop 2282, and a fixing screw hole 2285 is disposed on the first push plate 2281. The stabilizing rod 2283 is fixedly installed in the fixing screw hole 2285. The spring is sleeved outside the stabilizing rod 2283.

[0061] In this embodiment, a receiving notch 22811 is disposed on the first push plate 2281. The opening end of the receiving notch 22811 faces the reset stop 2282. The stabilizing rod 2283 is disposed at the bottom of the receiving notch 22811. The spring is in the receiving notch 22811. The receiving notch 22811 can increase the movement distance of the first push plate 2281 in the first direction X and the second direction Y, so as to accommodate different models of the battery 1 in the space limited by the first movable plate 2261, the second movable plate 2262, the first fixed plate 2263 and the second fixed plate 2264.

[0062] As shown Figure 14 in FIG. 4, the first push plate 2281 is slidably connected to the mover part through a slide rail slider assembly.

[0063] In another embodiment, the reset member 2284 may also be a shrapnel disposed between the first push plate 2281 and the reset stopper 2282, or other forms of reset members 2284, as long as it can provide a force for the first push plate 2281 to move towards the center direction of the receiving hole 220.

[0064] As shown Figure 10 and Figure 12 in FIGS. 5 and 6, the unlocking part 227 includes a first hooking part 2272. A second hooking part 2286 is provided on the first push plate 2281. When the mover part rotates relative to the outer ring 221 to the unlocking position, that is, when the rotary fixture 22 is in the unlocking position, the first hooking part 2272 can hook with the second hooking part 2286 to drive the first push plate 2281 so that it can move in a direction away from the center of the receiving hole 220. In this embodiment, a first telescopic member 2271 is provided on the base 20, and the first hooking part 2272 is provided at the telescopic end of the first telescopic member 2271. When unlocking is required, the first telescopic member 2271 drives the first hooking part 2272 to abut and hook to the second hooking part 2286, and the second telescopic member 251 continues to act so that the second hooking part 2286, that is, the first push plate 2281, moves in a direction away from the center of the receiving hole 220 to unlock the battery 1. Similarly, when the battery 1 needs to be locked, the first telescopic member 2271 drives the first hooking part 2272 to move in a direction close to the center of the receiving hole 220, and the first push plate 2281 moves in a direction close to the center of the receiving hole 220 under the action of the reset member 2284 so that the first moving plate 2261 moves towards the first fixed plate 2263 and the second moving plate 2262 moves towards the second fixed plate 2264.

[0065] As shown Figures 10 to 13As shown, the mover part includes a first rotating disk 223 and a second rotating disk 224 arranged at intervals. The two first rotating disks 223 and the second rotating disk 224 are connected by a rotating block 225. The accommodating hole 220 sequentially penetrates through the first rotating disk 223, the rotating block 225, and the second rotating disk 224. The first rotating disk 223 is arranged close to the positioning mechanism 21, and the second rotating disk 224 is arranged close to the transfer assembly 24. A pressing plate 226 is arranged on the first rotating disk 223. Avoidance grooves 2251 are arranged on the side walls of the accommodating hole 220 on the second rotating disk 224 and the rotating block 225. The transfer assembly 24 can extend into the avoidance grooves 2251, and the width of the avoidance grooves 2251 is smaller than the width of the battery 1. A first bearing surface 2252 for placing the battery 1 is configured on the inner wall of the accommodating hole 220, and the first bearing surface 2252 is distributed on at least one side of the avoidance grooves 2251. In this embodiment, the first rotating disk 223 is fixedly installed on the inner ring 222 of the rotating platform. When the inner ring 222 rotates relative to the outer ring 221, the mover part can rotate relative to the outer ring 221 following the inner ring 222. The avoidance grooves 2251 here are used to accommodate the transfer assembly 24, so that the battery 1 on the transfer assembly 24 can be disengaged from the transfer assembly 24 in the accommodating hole 220 and placed on the first bearing surface 2252, facilitating the placement of the battery 1 before positioning on the rotating fixture 22.

[0066] As Figure 12 and Figure 13 shown, in some embodiments, the rotating block 225 includes a block body 22501 and a connecting square frame 22502. The first rotating disk 223 and the second rotating disk 224 are connected by the connecting square frame 22502. The block body 22501 is installed on the square frame, and both the avoidance grooves 2251 and the first bearing surface 2252 are arranged on the block body 22501.

[0067] As Figure 11 and Figure 12 shown, an auxiliary plate is arranged on the second rotating disk 224, and the auxiliary plate is used to press the battery 1 on one side of the second rotating disk 224. In this embodiment, the auxiliary plate includes a first auxiliary moving plate 2210, a first auxiliary fixed plate 2212, a second auxiliary moving plate 2211, and a second auxiliary fixed plate 2213, which are correspondingly arranged with the first moving plate 2261, the first fixed plate 2263, the second moving plate 2262, and the second fixed plate 2264. Their working principles are the same and will not be elaborated here. Since the blade battery is long, the auxiliary plate on the second rotating disk 224 can cooperate with the pressing plate 226 on the first rotating disk 223 to improve the fixing stability of the rotating fixture 22 for the battery 1.

[0068] It should be noted that both the first auxiliary moving plate 2210 and the second auxiliary moving plate 2211 are movably assembled with the second rotating disk 224 through the aforementioned moving part 228 and are unlocked through the unlocking part 227 installed on the base 20.

[0069] It should be noted that in some embodiments, for the specific structures and installation layouts of the action part 228, specifically the first push plate 2281 and the reset stopper 2282, adaptive adjustments can be made according to factors such as the implementation structure space, etc., as long as the functions claimed in this embodiment can be achieved.

[0070] The transfer assembly 24 includes a moving part 241 and a working part 242. The working part 242 is used to transfer the battery 1, and the moving part 241 is used to drive the working part 242 to approach or move away from the rotary fixture 22; the working part 242 includes a first fixed seat 2421, a transfer plate 2422, and a bearing plate 2423. Among them, the transfer plate 2422 is movably installed on the first fixed seat 2421, and the transfer plate 2422 can move longitudinally relative to the first fixed seat 2421. The bearing plate 2423 is movably installed on the transfer plate 2422, and the moving direction of the bearing plate 2423 relative to the transfer plate 2422 is perpendicular to the moving direction of the transfer plate 2422 relative to the first fixed seat 2421. As Figure 9 , Figure 15 , Figure 16 and Figure 17 shown, the longitudinal direction is parallel to the first direction X, the moving direction of the bearing plate 2423 relative to the transfer plate 2422 is parallel to the second direction Y, and the bearing plate 2423 extends along the third direction Z towards the rotary fixture 22. During use, the battery 1 is placed on the bearing plate 2423, and the moving part 241 drives the working part 242 to move along the third direction Z, so as to realize the adjustment of the spatial position of the battery 1 on the transfer assembly 24, and accurately transfer the battery 1 to the corresponding rotary fixture 22.

[0071] Preferably, the transfer assemblies 24 and the rotary fixtures 22 are arranged in one-to-one correspondence, which can effectively improve the working efficiency of the welding device 2.

[0072] In this embodiment, a second bearing surface 24230 is provided on the bearing plate 2423, and a negative pressure suction cup 24231 is provided on the second bearing surface 24230. The battery 1 is placed on the second bearing surface 24230 and fixed by the negative pressure suction cup 24231, which can effectively improve the fixing efficiency of the battery 1 on the bearing plate 2423. At the same time, compared with the mechanical fixing method, the method using the negative pressure suction cup 24231 can effectively reduce the structural complexity of the bearing plate 2423, which is beneficial to smoothly send the battery 1 into the accommodation hole 220 and enter or exit the rotary fixture 22 through the avoidance groove 2251.

[0073] As Figure 16 and Figure 17As shown, a movable active correction plate 2424 is disposed on one side of the carrier plate 2423 close to the second bearing surface 24230. The active correction plate 2424 can move towards the battery 1 on the second bearing surface 24230 to drive it towards the positioning mechanism 21. The active correction plate 2424 cooperates with the positioning mechanism 21 to position the battery 1 in the third direction Z.

[0074] In this embodiment, the transfer plate 2422 and the first fixing base 2421, the carrier plate 2423 and the transfer plate 2422, and the active correction plate 2424 and the carrier plate 2423 are all slidably connected through a slide rail and slider assembly and driven by a cylinder.

[0075] As Figures 18 to 20 shown, the positioning mechanism 21 includes a second fixing base 211. A second push plate 212 is movably disposed on the second fixing base 211. A reference block 213 is disposed on the second push plate 212 for positioning the battery 1 in the length direction of the battery 1 in cooperation with the transfer assembly 24. In this embodiment, the length direction of the battery 1 is parallel to the third direction Z. Here, the positioning mechanism 21, specifically, the reference block 213 is the positioning reference of the battery 1 in the welding device 2 before welding, so as to cooperate with the transfer assembly 24 to accurately position and assemble the battery 1 in the rotary fixture 22. Here, the second push plate 212 is slidably connected to the second fixing base 211 through a slide rail and slider assembly, and the sliding direction of the second push plate 212 relative to the second fixing base 211 is parallel to the third direction Z. During use, the active correction plate 2424 drives the battery 1 towards the reference block 213 until the battery 1 abuts against the reference block 213 to achieve the positioning of the battery 1 in the third direction Z. Subsequently, the battery 1 is clamped and fixed by the rotary fixture 22, the reference block 213 moves along the third direction Z to disengage from the battery 1, and finally the welding mechanism 23 cooperates with the rotary fixture 22 to perform welding on the battery 1. Here, the second push plate 212 is driven by a cylinder installed on the second fixing base 211.

[0076] In another embodiment, a follower shaft 214 is rotatably installed on the second push plate 212, and the reference block 213 is connected to the second push plate 212 through the follower shaft 214. Further, the follower shaft 214 is rotatably connected to the second push plate 212 through a bearing. During use, specifically, during the welding process, the reference block 213 always adheres to the top cover of the battery 1 and rotates synchronously with the battery 1 under the action of the rotary fixture 22. This can play a role in following and straightening the top cover of the battery 1, reducing the risk of the top cover of the battery 1 shifting during the welding process due to insufficient pre-welding between the top cover of the battery 1 and the housing.

[0077] Further, a protection groove 2131 for accommodating the pole column is disposed on the reference block 213. During use, the pole column is embedded in the protection groove 2131, which ensures that the pole column will not be damaged during the welding process and guarantees the quality of the battery 1.

[0078] In some embodiments, a second cooling air passage is provided in the reference block 213.

[0079] In this embodiment, the first telescopic member 2271 and the second telescopic member 251 include, but are not limited to, air cylinders or electric push rods.

[0080] In this embodiment, the welding mechanism 23 is an existing laser welding device.

[0081] As Figure 2 shown, during use, the feeding assembly 32 feeds the battery 1 to the welding device 2 near the right side in the second direction Y, specifically the transfer assembly 24 of the welding device 2, and completes the lid welding of one end of the battery 1 through cooperation with the rotating fixture 22; subsequently, the transfer assembly 24 unloads the battery 1 from the rotating fixture 22, and transports it to the transfer assembly 6 through the feeding assembly 32. After the end lids of the battery 1 are swapped in the length direction, it is then transported to the left by the feeding assembly 32 along the second direction Y to the transfer assembly 24 of the welding device 2 on the left side, and the lid welding of the other end of the battery 1 is achieved through cooperation with the rotating fixture 22. After the welding is completed, the transfer assembly 24 of the welding device 2 on the left side unloads the battery 1 and transports it to the upper side of the guide seat beam 31 along the third direction Z, that is, to the same side as the rolling mechanism 7 and the post-welding inspection assembly 4, and then various processing items are completed through the feeding assembly 32.

[0082] As Figure 2 and Figure 25 shown, in this embodiment, the transfer assembly 6 includes a linear module provided on the frame 5 and a carrier platform 61 provided on the linear module. The carrier platform 61 is used to carry the battery 1, and the carrier platform 61 is rotatably connected to the linear module through a rotating platform. Here, the linear module is used to move the carrier platform 61 along the second direction Y.

[0083] Here, the rolling mechanism 7 is used to roll flat the weld on the long side of the battery lid, and it can be any existing rolling structure. Further, as Figures 21 to 24 , the post-welding inspection assembly 4 includes a battery carrier 42 and an inspection mechanism 41. The battery carrier 42 is used to clamp the battery 1; the inspection mechanism 41 is located on the side of the battery carrier 42 and is provided near the end in the length direction of the battery 1; the battery carrier 42 includes a fixed bracket 421 and a clamping part 422. The clamping part 422 is adjustably assembled on the fixed bracket 421, and the battery 1 is arranged on the clamping part 422. The clamping part 422 can be adjusted relative to the fixed bracket 421 so that the long side and the short side of the battery lid are respectively in the inspection position. Here, the attitude of the battery 1 is adjusted through the battery carrier 42, so that the long side and the short side of the welded battery lid can respectively reach the inspection position, and thus the inspection of the long side and the short side of the battery lid can be completed by using the same inspection mechanism 41, effectively saving costs.

[0084] In this embodiment, the clamping part 422 includes a fixed bottom plate 4221, which is rotatably connected to the fixed bracket 421; a support plate 4222 and a pneumatic gripper 4223 are provided on the fixed bottom plate 4221, and the battery 1 is placed on the support plate 4222 and fixed by the pneumatic gripper 4223; a first driving structure 423 is provided on the fixed bracket 421, which is used to drive the fixed bottom plate 4221 to rotate relative to the fixed bracket 421. Optionally, the first driving structure 423 includes a motor 4231 and a cross-direction gear 4232, and the fixed bottom plate 4221 is rotatably connected to the fixed bracket 421 through the cross-direction gear 4232. The motor 4231 is installed on the fixed bracket of the clamping part 422, and is used to drive the cross-direction gear 4232 to operate to realize the flipping of the fixed bottom plate 4221, thereby realizing the flipping of the battery 1 to switch the long side and the short side of the battery top cover so that they are respectively in the detection position, so as to cooperate with the detection mechanism 41 for detection.

[0085] In another embodiment, the fixed base plate 4221 can be installed on the fixed bracket 421 through a rotating shaft, and a motor is disposed on the fixed bracket 421, and the output shaft of the motor is drivingly connected to the rotating shaft.

[0086] In this embodiment, a rotating mounting seat 42211 is provided on the fixed base plate 4221, the support plate 4222 and the pneumatic gripper 4223 are installed on the first side surface 4201 of the fixed base plate 4221, the rotating mounting seat 42211 is provided on the second side surface 4202 of the fixed base plate 4221, and the rotating mounting seat 42211 is installed on the output shaft of the cross-steering gear 4232.

[0087] like Figure 21 , Figure 22 and Figure 24 As shown, a second limiting notch 42221 is formed on the support plate 4222, and the battery 1 is located in the second limiting notch 42221. The second limiting notch 42221 is used to initially limit the battery 1 so as to cooperate with the mechanical gripper to fix the battery 1.

[0088] like Figure 21 and Figure 22As shown in the figure, the detection mechanism 41 includes a second driving structure 411 and a moving plate 412. The second driving structure 411 is used to drive the moving plate 412 to move. A first detection module 413 and a second detection module 414 are arranged on the moving plate 412. When the battery 1 is in the detection position, the battery 1 is within the detection areas of the first detection module 413 and the second detection module 414. Here, the first detection module 413 and the second detection module 414 are 3D cameras. The second driving structure 411 is a linear module. In this embodiment, the battery 1 is a blade battery, and there are battery top covers at both ends in the length direction of the battery 1. Therefore, the post-welding detection assembly 4 here includes two detection mechanisms 41, which are correspondingly arranged at both ends of the battery 1 to improve the detection efficiency.

[0089] Of course, in other embodiments, the post-welding detection assembly 4 can also be applied to the detection after the welding of the top covers of other types of square shell batteries, and the detection mechanism 41 is specifically set according to the number of top covers.

[0090] When in use, as Figure 21 shown, it is the first state of the battery carrier 42. At this time, the long side of the battery top cover is in the detection position. At this time, the second driving structure 411 drives the moving plate 412, that is, the first detection module 413 and the second detection module 414, to move along the detection direction W to complete the detection of the long side. Subsequently, under the action of the first driving structure 423, the clamping part 422 flips forward along the detection direction W so that the battery carrier 42 is in the second state as shown in Figure 22 shown. At this time, the short side of the battery top cover is in the detection position. At this time, the second driving structure 411 drives the moving plate 412, that is, the first detection module 413 and the second detection module 414, to move along the detection direction W to complete the detection of the short side. In this embodiment, the detection direction W is parallel to the second direction Y.

[0091] Furthermore, a linear module is arranged on the moving plate 412. The first detection module 413 and the second detection module 414 are respectively movably assembled on the moving plate 412 through the linear module. When in use, the battery 1 is between the first detection module 413 and the second detection module 414. The movably assembled manner of the first detection module 413 and the second detection module 414 on the moving plate 412 enables the distance between the first detection module 413 and the second detection module 414 and the battery 1 to be adjusted, which is convenient for detecting the long side and the short side.

[0092] As Figure 23 and Figure 24As shown, a stop bar 4211 and a limit pin 4212 are provided on the fixed bracket 421 for limiting and fixing the bottom plate 4221. Specifically, when the long side of the battery top cover is detected, the second side 4202 of the fixed bottom plate 4221 abuts against the stop bar 4211; when the short side of the battery top cover is detected, the rotating mounting seat 42211 abuts against the limit pin 4212.

It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
