Because the first clamping block 341 is disposed on the surface of the first clamping plate 32 facing the second clamping plate 33, the second driving member 342 is connected to the second clamping plate 33, and the second driving member 342 is opposite to the first clamping block 341, when the second driving member 342 extends and retracts, the gap between the second driving member 342 and the first clamping block 341 changes, so that the second driving member 342 and the first clamping block 341 clamp the battery cell 001 to be welded in the direction from the second clamping plate 33 to the first clamping plate 32. That is, by providing the second driving member 342 and the first clamping block 341, it is possible to facilitate clamping of the battery cell 001 to be welded in the direction from the second clamping plate 33 to the first clamping plate 32.

It should be noted that, in the embodiment of the present invention, the second clamping plate 33 may be provided with a mounting hole, and the second driving member 342 is disposed through the mounting hole, so that the second driving member 342 is connected to the second clamping plate 33. Of course, the second driving member 342 may be mounted on the surface of the second clamping plate 33 facing the first clamping plate 32. The embodiment of the present invention is not limited herein as to the specific manner in which the second driving member 342 is connected to the second clamping plate 33.

Certainly, the type of the second driving element 342 may also be another type, for example, the second driving element 342 is a motor, an output shaft of the motor is connected to a lead screw, a slider is sleeved on the lead screw, a gap is formed between the slider and the first clamping block 341, and when the motor runs, the slider moves along the lead screw, so that the slider and the first clamping block 341 clamp the electric core 001 to be welded. The embodiment of the present invention is not limited to the specific type of the second driving member 342.

It should be further noted that the material of the first clamping block 341 may be a rubber material, and at this time, when the to-be-welded battery cell 001 is clamped, the damage to the surface of the to-be-welded battery cell 001 by the first clamping block 341 is small. Of course, the material of the first clamping block 341 may also be other materials, for example, the material of the first clamping block 341 is a metal material, and the embodiment of the present invention is not limited herein for the specific material of the first clamping block 341.

In addition, in some embodiments, a third clamping block 345 may be connected to the second driving element 342, the third clamping block 345 is opposite to the first clamping block 341, and the third clamping block 345 and the first clamping block 341 are configured to clamp the battery cell 001 to be welded.

When the third clamping block 345 is far away from the first clamping block 341, a gap between the third clamping block 345 and the first clamping block 341 is large, the battery cell 001 to be welded can be placed between the third clamping block 345 and the first clamping block 341, then the second driving part 342 drives the third clamping block 345 to be close to the first clamping block 341, and the third clamping block 345 and the first clamping block 341 can clamp the battery cell 001 to be welded. In addition, when the third clamping block 345 and the first clamping block 341 clamp the to-be-welded battery core 001, at this time, two opposite surfaces of the to-be-welded battery core 001 are respectively in contact with the first clamping block 341 and the third clamping block 345, so that the first clamping block 341 and the third clamping block 345 can clamp the to-be-welded battery core 001 more tightly, and the first clamping block 341 and the third clamping block 345 can also damage the surface of the to-be-welded battery core 001 less. That is, by providing the third clamping block 345, damage to the surface of the battery cell 001 to be welded when clamping the battery cell 001 to be welded can be reduced.

The material of the third clamping block 345 may be the same as the material of the first clamping block 341, for example, when the material of the first clamping block 341 is rubber, the material of the third clamping block 345 is rubber. Of course, the material of the third clamping block 345 is different from that of the first clamping block 341, for example, the material of the first clamping block 341 is metal, and the material of the third clamping block 345 is rubber. Therefore, the embodiments of the present invention are not limited herein.

Additionally, in some embodiments, clamp assembly 34 may further include a third drive member 343. The third driving member 343 is located between the first clamping plate 32 and the second clamping plate 33, and the third driving member 343 is configured to stretch in a direction parallel to the first clamping plate 32 to clamp the battery cell 001 to be welded.

Because the third driving member 343 is located between the first clamping plate 32 and the second clamping plate 33, when the cell 001 to be welded needs to be clamped, the third driving member 343 can stretch out and draw back in the direction parallel to the first clamping plate 32, so as to clamp the cell 001 to be welded in the direction parallel to the first clamping plate 32, and thus the cell 001 to be welded can be clamped not only in the direction from the first clamping plate 32 to the second clamping plate 33, but also in the direction parallel to the first clamping plate 32, so that the cell 001 to be welded is welded more firmly, that is, by providing the third driving member 343, it is more favorable to clamping the cell 001 to be welded.

It should be noted that the third driving member 343 may be connected to the first clamping plate 32, the second clamping plate 33, and the connecting plate 31. When the third driving member 343 is connected to the first clamping plate 32, the third driving member 343 may be connected to a surface of the first clamping plate 32 facing the second clamping plate 33, such that the third driving member 343 is connected to the first clamping plate 32, and of course, the third driving member 343 may be connected to the first clamping plate 32 in other manners, and a mounting through hole may be further provided on the first clamping plate 32, and the third driving member 343 may be at least partially mounted in the mounting through hole. The embodiment of the present invention is not limited herein as to the specific manner of connecting the third driving member 343 to the first clamping plate 32. When the third driving member 343 is connected to the second clamping plate 33, the third driving member 343 may be connected to a surface of the second clamping plate 33 facing the second clamping plate 33, such that the third driving member 343 is connected to the second clamping plate 33, of course, the third driving member 343 may be connected to the second clamping plate 33 in other manners, and a mounting through hole may be further provided on the second clamping plate 33, and the third driving member 343 may be at least partially mounted in the mounting through hole. The embodiment of the present invention is not limited herein as to the specific manner of connecting the third driving member 343 to the second clamping plate 33. When the third driving member 343 is connected to the connecting plate 31, the third driving member 343 may be disposed on the surface of the connecting plate 31, and the connecting plate 31 may also be disposed with a mounting hole, and the third driving member 343 is disposed in the mounting hole, and is connected to the specific manner of the connecting plate 31 for the third driving member 343, embodiments of the present invention are not limited herein.

In addition, when clamping the cell to be welded, the second driving member 342 may be first operated, that is, the second driving member 342 and the first clamping block 341 clamp the cell 001 to be welded in the direction from the first clamping plate 32 to the second clamping plate 33, and then the third driving member 343 is moved so that the third driving member 343 clamps the cell 001 to be welded in the direction parallel to the first clamping plate 32. Of course, it is also possible to first operate the third drive 343, that is, the third drive 343 grips the cell 001 to be welded in a direction parallel to the first clamping plate 32, and then move the second drive 342, and the second drive 342 grips the cell 001 to be welded with the first gripping block 341 in a direction from the first clamping plate 32 to the second clamping plate 33. Of course, it is also possible to operate the second drive 342 and the third drive 343 simultaneously. The operation sequence of the second driving member 342 and the third driving member 343 is not limited herein.

In addition, as shown in fig. 1, when the number of the lifting structures 10, the number of the first driving members 20, and the number of the clamping structures 30 are two, the surface of the first clamping plate 32 of one first clamping structure 30 facing the second clamping plate 33 is provided with one third driving member 343. The two third driving members 343 may operate simultaneously, so that the two third driving members 343 clamp two sides of the battery cell 001 to be welded simultaneously in a direction parallel to the first clamping plate 32.

In addition, in some embodiments, a second clamping block 344 may be connected to the third driving member 343, and the second clamping block 344 is used for clamping the battery cell 001 to be welded along a direction parallel to the first clamping plate 32.

When the third driving member 343 is connected to the second clamping block 344, at this time, the third driving member 343 may drive the second clamping block 344 to move, so as to clamp, by the second clamping block 344, the battery cell 001 to be welded along a direction parallel to the first clamping plate 32. In addition, when the second clamping block 344 clamps the battery cell 001 to be welded, it may be avoided that the third driving member 343 directly contacts the battery cell 001 to be welded, that is, the second clamping block 344 directly contacts the battery cell 001 to be welded, and the second clamping block 344 has less damage to the battery cell 001 to be welded. That is, by providing the second clamping block 344, it is possible to cause less damage to the battery cell 001 to be welded while clamping the battery cell 001 to be welded in a direction parallel to the first clamping plate 32.

The material of the second clamping block 344 may be the same as the material of the first clamping block 341, for example, when the material of the first clamping block 341 is rubber, the material of the second clamping block 344 is rubber. Of course, the material of the second clamping block 344 is different from the material of the first clamping block 341, for example, the material of the first clamping block 341 is metal, and the material of the second clamping block 344 is rubber. Therefore, the embodiments of the present invention are not limited herein.

It should be further noted that, when the battery cell 001 to be welded includes a battery case and a cover plate, after the second clamping block 344 moves under the action of the third driving member 343, the second clamping block 344 abuts against the cover plate, so as to tightly push the cover plate against the battery case, thereby facilitating subsequent welding on the battery cell 001 to be welded.

In addition, in some embodiments, the first clamping plate 32 and/or the second clamping plate 33 may be provided with a welding hole 321, and the welding hole 321 is used for enabling the welding head 104 to weld the battery cell 001 to be welded.

Because the welding holes 321 are formed in the first clamping plate 32 and/or the second clamping plate 33, when the cell 001 to be welded is subjected to laser spot welding, laser emitted by the welding head 104 can pass through the welding holes 321 in the first clamping plate 32 or the second clamping plate 33, so that the laser irradiates on the cell 001 to be welded between the first clamping plate 32 and the second clamping plate 33, and the cell 001 to be welded is welded. That is, by providing the welding holes 321 on the first clamping plate 32 and/or the second clamping plate 33, the welding head 104 can facilitate welding the battery cell 001 to be welded.

It should be noted that, in the embodiment of the present invention, the welding hole 321 may be only provided on the first clamping plate 32, the welding hole 321 may also be only provided on the second clamping plate 33, and of course, the welding holes 321 may also be provided on the first clamping plate 32 and the second clamping plate 33 at the same time.

Additionally, in embodiments of the present invention, the welding head 104 may be a laser welding head.

Additionally, in some embodiments, the clamping assembly may further include a third driving member 343, the third driving member 343 being located between the first clamping plate 32 and the second clamping plate 33, the second clamping block 344 being connected to the third driving member 343. A distance sensor 35 is disposed between the first clamping plate 32 and the second clamping plate 33, and the distance sensor 35 is used for detecting the distance between the second clamping block 344 and the distance sensor 35. When the distance sensor 35 is disposed on the surface of the first clamping plate 32 facing the second clamping plate 33, at this time, when the cell 001 to be welded is clamped in the direction parallel to the first clamping plate 32, the third driving member 343 may drive the second clamping block 344 to move, so that the distance sensor 35 may detect the distance between the second clamping block 344 and the distance sensor 35, and then determine whether the second clamping block 344 moves to a proper position, or whether a position deviation occurs in the cell 001 to be welded in the direction parallel to the first clamping plate 32.

Wherein, in the embodiment of the present invention, the surface of the first clamping plate 32 facing the second clamping plate 33 may be provided with the distance sensor 35, or the surface of the second clamping plate 33 facing the first clamping plate 32 may be provided with the distance sensor 35, or the surface of the connecting plate 31 is provided with the distance sensor 35. The embodiment of the present invention is not limited herein for the specific setting position of the distance sensor.

When the distance sensor 35 is disposed on the surface of the second clamping plate 33 facing the first clamping plate 32, at this time, when the cell 001 to be welded is clamped in the direction parallel to the first clamping plate 32, the third driving member 343 may drive the second clamping block 344 to move, so that the distance sensor 35 may detect the distance between the second clamping block 344 and the distance sensor 35, and then it may be determined whether the second clamping block 344 has moved to a proper position, or whether a positional deviation of the cell 001 to be welded occurs in the direction parallel to the first clamping plate 32.

Since the distance sensor 35 is electrically connected to the controller, the distance sensor 35 can transmit the detected distance information to the controller, and the controller can control the movement of the bonding head. Therefore, when different batches of the battery cores 001 to be welded are subjected to spot welding, due to the fact that small errors exist in the lengths of the different batches of the battery cores 001 to be welded, when the cover plate and the battery shell are tightly pressed by the second clamping block 344, distance information detected by the distance sensor 35 may be different, and therefore the controller can determine whether the welding head is aligned with the welding seam or not according to the distance information detected by the distance sensor 35, and if the welding head is not aligned with the welding seam, the controller can control the welding head to move so that the welding head is aligned with the welding seam. That is, the distance sensor 35 detects the distance between the second clamping block 344 and the distance sensor 35, which can facilitate the controller to adjust the welding head so that the welding head is aligned with the welding seam, thereby avoiding the problem that the welding head may not be aligned with the welding seam and the welding quality is affected due to the different lengths of the battery cores 001 to be welded in different batches. That is, by providing the distance sensor 35, the distance sensor 35 detects the distance between the second clamping block 344 and the distance sensor 35, so that the controller can precisely adjust the position of the welding head, and finally the welding quality can be improved.

The following describes the use process of the welding system according to the embodiment of the present invention with reference to fig. 3 and 4:

when the battery core 001 to be welded needs to be welded, the battery to be welded may be placed between the second driving element 342 and the first clamping block 341, and the battery core 001 to be welded is clamped by the second driving element 342 and the first clamping block 341, and at this time, the battery core is in a horizontal state. And then the lifting structure 10 is lifted, that is, the lifting structure 10 drives the first driving member 20 and the clamping structure 30 to lift. After the lifting structure 10 is lifted to a proper position, the first driving member 20 drives the clamping structure 30 to rotate, so that the battery cell 001 to be welded is in a vertical state, and the welding position of the battery cell to be welded corresponds to the welding head 104, so that the welding head 104 can weld one surface of the battery to be welded from the position of the first clamping plate 32 or the second clamping plate 33. When the welding head 104 performs welding, the welding head 104 moves from top to bottom, so that after welding of one surface of the battery to be welded is completed, the first driving part 20 can drive the clamping structure 30 to rotate, so that the other surface of the battery cell 001 to be welded faces the welding head 104, then the lifting structure 10 can drive the first driving part 20 and the clamping structure 30 to descend, and after the welding holes 321 in the first clamping plate 32 or the second clamping plate 33 correspond to the welding head 104, the other surface of the battery cell 001 to be welded is welded by the welding head 104. After the welding is finished, the cell can be driven to descend by the lifting structure 10.
