[0031] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0032] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0033] Now, a further description of the preferred embodiments of the present utility model will be given in conjunction with the accompanying drawings, as Figure 3As shown in the figure, an automatic battery welding device includes a feeding device 100. A turntable 200 is arranged on one side of the feeding device 100. A feeding position 200a, a waiting position 200b, a welding position 200c and a discharging position 200d are sequentially arranged on the turntable 200. A protection plate conveying assembly 300 is arranged on one side of the waiting position 200b. The protection plate conveying assembly 300 includes a first supporting device 310 and a clamping device 320. A welding assembly 400 is arranged opposite to each other above and below the welding position 200c. The welding assembly 400 includes a welding device 410 arranged above the welding position 200c and a second supporting device 420 arranged below the welding position 200c. Both the welding device 410 and the second supporting device 420 include lifting devices. A discharging device 500 and a discharging conveyor belt 600 are arranged above the discharging position 200d.

[0034] This application is a device for welding the connecting part 21 of the protection plate 20 to the ear 11 of the battery plate 10. In its working state, the feeding device 100 first sucks the battery plate 10 from the device in the previous link, turns it after sucking, makes its ear 11 face the outside of the turntable 200 uniformly, and then places it on the feeding position 200a of the turntable 200. Then the turntable 200 is started to rotate. When the battery plate 10 rotates from the feeding position 200a to the waiting position 200b, the protection plate 20 is placed on the first supporting device 310, and its connecting part 21 is aligned with the welding position 200c. Then the clamping device 320 is started to clamp the protection plate 20 from the first supporting device 310 and move it towards the welding position, place the protection plate 20 on the second supporting device 420, and align the connecting part 21 of the protection plate 20 with the ear 11 of the battery plate 10. Then the lifting device is started to make the welding device 410 and the second supporting device 420 move towards each other, so that the connecting part 21 of the protection plate 20 and the ear 11 of the battery plate 10 are in protective contact, and then the connecting part 21 and the ear 11 are welded together by the welding device 410. Then the turntable 200 moves the welded battery plate 10 to the discharging position 200d, and then the discharging device 500 is used to move the battery plate 10 to the discharging conveyor belt 600.

[0035] Compared with the prior art, in this application, the feeding process of the battery panel 10 is fully automated by the feeding device 100 and the turntable 200. Then, the connecting part 21 of the protection plate 20 and the ear 11 of the battery panel 10 are welded together by the protection plate conveying component 300 and the welding component 400. Except for manually placing the protection plate 20 on the first supporting device 310, the rest of the processes are all automatically completed, enabling welding operations to be carried out at a stable speed and rhythm, without being affected by factors such as manual fatigue and rest, and can work continuously and efficiently. Compared with manual welding, its welding speed is greatly improved, and a large number of welding tasks can be completed in a short time, thus significantly improving production efficiency and meeting the needs of large-scale production.

[0036] Furthermore, based on the above embodiments, as Figure 4 shown, the feeding device 100 includes a first sliding seat 110 and a first guide rail 120. The first sliding seat 110 can slide along the first guide rail 120. A first lifting cylinder 130 is installed on the first sliding seat 110. A first steering motor 140 and a first connecting plate 150 are arranged at the bottom of the first lifting cylinder 130. The first steering motor 140 is used to drive the first connecting plate 150 to rotate. A suction cup 160 is arranged at the bottom of the first connecting plate 150. After starting the first lifting cylinder 130 to control the suction cup 160 to descend to suck the battery panel 10 from the equipment of the previous link, the first steering motor 140 is used for steering, so that the ear 11 of the battery panel 10 faces the outside of the turntable. Then, the first lifting cylinder 130 is used to control the suction cup 160 to place the battery panel 10 on the feeding position 200a.

[0037] Furthermore, based on the above embodiments, in combination with Figure 3 and Figure 5 shown, limiting devices 210 are arranged on the feeding position 200a, waiting position 200b, welding position 200c and discharging position 200d of the turntable 200. The limiting device 210 includes a fixed plate 211 and a movable plate 212. The battery panel 10 is placed between the fixed plate 211 and the movable plate 212. A regulating plate 213 is connected to the side of the movable plate 212 away from the fixed plate 211. A second sliding seat 214 and a second guide rail 215 are arranged at the bottom of the regulating plate 213. The second sliding seat 214 can be used to slide on the second guide rail 215, thereby realizing the movement of the regulating plate 213, and further bringing the effect of adjusting the distance between the movable plate 212 and the fixed plate 211, so that the fixed plate 211 and the movable plate 212 can adapt to battery panels 10 of any size.

[0038] Furthermore, based on the above embodiments, as Figure 6As shown, the first supporting device 310 includes a first supporting plate 311. Two first supporting members 312 for supporting the connecting portion 21 of the protection plate 20 are provided on the first supporting plate 311. A first groove 311a is provided on the first supporting plate 311. The first supporting members 312 can move along the first groove 311a, so that the distance between the two first supporting members 312 can be adjusted. The first supporting plate 311 is connected to a second lifting cylinder 314 through a second connecting plate 313. When the second lifting cylinder 314 is started, it can drive the first supporting plate 311 to perform a lifting movement. In the working state, first, the distance between the first supporting members 312 is adjusted to a suitable distance to adapt to different tab 11 specifications, and then the connecting portion 21 of the protection plate 20 is placed on the first supporting members 312. When the clamping device 320 comes to clamp the protection plate 20, the second lifting cylinder 314 is started to lift the first supporting plate 311 to a preset height, so as to facilitate the clamping of the protection plate 20 by the clamping device 320.

[0039] In some embodiments, as Figure 6 shown, a first supporting plate 315 is provided on one side of the second lifting cylinder 314 and at the bottom of the first supporting plate 311. A third sliding seat 316, a third guide rail 317 and a first driving cylinder 318 are provided at the bottom of the first supporting plate 315. The third guide rail 317 is arranged towards the welding position 200c. The first driving cylinder 318 is used to drive the third sliding seat 316 to move along the third guide rail 317, so that the second lifting cylinder 314 and the first supporting plate 311 can be driven to move along the third guide rail 317. In this way, the second lifting cylinder 314 and the first supporting plate 311 can be driven to move towards the welding position 200c, thereby reducing the moving distance of the clamping device 320 and accelerating the cooperation efficiency between the clamping device 320 and the first supporting device 310.

[0040] On the basis of the above embodiments, further Figure 6 and Figure 7As shown, the clamping device 320 includes a first motor 321 and a first transmission lead screw 322. A fourth sliding seat 323 is sleeved on the first transmission lead screw 322. The first transmission lead screw 322 is arranged towards the welding position 200c and is parallel to the third guide rail 317. The first motor 321 is used to drive the first transmission lead screw 322 to rotate so as to drive the fourth sliding seat 323 to slide along the first transmission lead screw 322. A second driving cylinder 324 and a third lifting cylinder 325 are arranged on the fourth sliding seat 323. The third lifting cylinder 325 is installed on the driving end of the second driving cylinder 324. A clamping member 326 is arranged at the bottom of the third lifting cylinder 325. After the protection plate 20 is placed in place, the first motor 321 drives the fourth sliding seat 323 along the first transmission lead screw 322 to come opposite to the first supporting plate 311. The second driving cylinder 324 and the third lifting cylinder 325 drive the clamping member 326 to extend forward and lift to a suitable position. Then, the clamping member 326 is opened to clamp the protection plate 20, and then it is moved to the opposite of the second supporting device 420 and the protection plate 20 is placed on the second supporting device 420. It should be noted that how to open and close the clamping member 326 is a common technique in the art and will not be further elaborated here. At the same time, it should be noted that when the first motor 321 drives the fourth sliding seat 323 to move along the first transmission lead screw 322, the first driving cylinder 318 can also drive the third sliding seat 316 to move along the third guide rail 317. In this way, the clamping member 326 and the first supporting plate 311 move towards each other, thus accelerating the cooperation efficiency between the clamping device 320 and the first supporting device 310.

[0041] Furthermore, on the basis of the above embodiments, such as Figure 8As shown, the second supporting device 420 includes two independent second supporting plates 421. A second groove 421a is provided at the top of the second supporting plate 421, and a second supporting member 422 is provided in the second groove 421a. After the solar panel 10 moves to the welding position 200c, the clamping device 320 places the connecting portion 21 of the protection plate 20 on the second supporting member 422. The second supporting member 422 can move along the second groove 421a to adjust the distance between the second supporting members 422. A fourth lifting cylinder 423 is provided at the bottom of the second supporting plate 421. The fourth lifting cylinder 423 can control the synchronous lifting of the second supporting plate 421. The fourth lifting cylinder 423 is installed on a fifth sliding seat 424. The fifth sliding seat 424 is sleeved on a second transmission screw rod 425. The second transmission screw rod 425 is connected to a second motor 426. When the distance requirement between the second supporting members 422 cannot be met by using the second groove 421a, the second motor 426 can drive the fifth sliding seat 424 to move along the second transmission screw rod 425, so as to drive the fourth lifting cylinder 423 and the second supporting plate 421 to move integrally, so as to achieve the purpose of adjusting the distance between the second supporting plates 421. At the same time, compared with the adjustment method using the second groove 421a, the overall adjustment of the distance between the second supporting plates 421 by the second motor 426 can be adjusted in real time during the welding process, so that the two adjustment methods can cooperate with each other, that is, first manually adjust the distance between the second supporting members 422, and then during the welding process, the second motor 426 is used to perform a secondary adjustment of the distance between the second supporting plates 421.

[0042] Furthermore, on the basis of the above embodiments, as Figure 9As shown, the welding device 410 includes two independent welding torches 411. A fifth lifting cylinder 412 is provided at the top of the welding torch 411. The fifth lifting cylinder 412 can control the synchronous lifting of the welding torch 411. The fifth lifting cylinder 412 is installed on a sixth sliding seat 414. The sixth sliding seat 414 is sleeved on a second transmission lead screw 425. The second transmission lead screw 425 is connected to a second motor 426. The second motor 426 can drive the sixth sliding seat 414 to move along the second transmission lead screw 425, thereby driving the fifth lifting cylinder 412 and the welding torch 411 to move as a whole, so as to adjust the distance between the welding torches 411, making the welding torch 411 correspond to the second supporting member 422, that is, the welding torch 411 is directly above the second supporting member 422. After the clamping device 320 places the connecting portion 21 of the protection plate 20 on the second supporting member 422, the second motor 426 adjusts the distance between the welding torches 411 to make it directly above the second supporting member 422, and then the fourth lifting cylinder 423 and the fifth lifting cylinder 412 are started to drive the second supporting member 422 and the welding torch 411 to move upward and downward towards each other, thereby welding the connecting portion 21 and the pole ear 11.

[0043] Furthermore, on the basis of the above-mentioned embodiment, as Figure 10 shown. The blanking device 500 includes a second steering motor 510 and a third connecting plate 520. The third connecting plate 520 is installed on the top of the second steering motor 510. A sixth lifting cylinder 530 is provided at the bottom of the second steering motor 510. A suction cup 160 is provided at the bottom of the third connecting plate 520. After the battery panel 10 completed with welding moves from the welding position 200c to the blanking position 200d, the sixth lifting cylinder 530 drives the suction cup 160 to descend to adsorb the battery panel 10, and then the second steering motor 510 is started to move the suction cup 160 above the discharge conveyor belt 600, and then the sixth lifting cylinder 530 is used to drive the suction cup 160 to descend to place the battery panel 10 on the discharge conveyor belt 600.
