[0041] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0042] This embodiment provides a battery electrode tab welding device for welding battery tabs onto the electrode sheet. Specifically, as shown... Figure 1 As shown, the battery electrode tab welding device includes a conveying assembly 1, a cutting assembly 2, a welding assembly 3, and a dust removal assembly 4.
[0043] like Figure 1 As shown, the conveying assembly 1 includes a conveyor belt 11 and a positioning element 12. The positioning element 12 is configured to place and position the electrode 100, and the conveyor belt 11 is used to transport the positioning element 12 and the electrode 100 to the welding position. In other words, the conveying assembly 1 is used to load and transport the electrode 100. The electrode 100 only needs to be placed on the positioning element 12 on the conveyor belt 11, and the electrode 100 can be transported to the welding position by the conveyor belt 11. There is no need to remove the electrode 100 from the conveyor belt 11, and the pre-cut electrode tab 202 can be welded to the electrode 100. This saves the electrode 100 handling and positioning process and effectively improves the welding accuracy and welding efficiency between the electrode 100 and the pre-cut electrode tab 202.
[0044] Specifically, the positioning component 12 has a positioning groove, which forms a clearance opening on one side of the conveyor belt 11 parallel to the conveying direction. The electrode 100 is embedded in the positioning groove, and the welding end of the electrode 100 extends out of the positioning groove through the clearance opening. By making the welding end of the electrode 100 extend out of the positioning groove, that is, the welding end of the electrode 100 is suspended, the electrode 100 can be welded without removing it.
[0045] More specifically, the conveying assembly 1 further includes a second driving member 13 and a transmission wheel 14. The output end of the second driving member 13 is connected to the transmission wheel 14. The conveyor belt 11 is wound around the transmission wheel 14, and the output end of the second driving member 13 drives the transmission wheel 14 to rotate, thereby driving the conveyor belt 11 to rotate. In this embodiment, the second driving member 13 can be a motor, and the transmission wheel 14 is a synchronous pulley. When the motor starts, it drives the synchronous pulley to rotate, thereby driving the conveyor belt 11 to move, realizing the transmission of the positioning member 12 and the electrode plate 100.
[0046] More specifically, the conveying assembly 1 also includes a positioning detection element 15. Along the conveying direction of the conveyor belt 11, the positioning detection element 15 is located upstream of the cutting assembly 2 and the welding assembly 3. The positioning detection element 15 is used to output detection light to the electrode 100 on the positioning element 12 on the conveyor belt 11, thereby determining the position of the electrode 100 on the conveyor belt 11. Exemplarily, the positioning detection element 15 can be selected as a photoelectric sensor in the prior art.
[0047] In the embodiment, the conveying assembly 1 is used to realize the feeding and conveying of the pole piece 100. The second driving member 13 is started to rotate the transmission wheel 14 clockwise to drive the conveying belt 11 to move forward. The positioning member 12 of the pole piece 100 is placed on the conveying belt 11 and moves with the rotation of the conveying belt 11. The in-place detection member 15 is responsible for sensing the position of the pole piece 100 on the conveying belt 11.
[0048] With reference to the drawings Figure 1 , the cutting assembly 2 and the welding assembly 3 are arranged on the two sides of the welding position, which helps to shorten the overall length of the battery pole piece tab welding device, makes the structure between each component more compact, and saves the design and assembly cost.
[0049] As shown in Figures 1-3 , the cutting assembly 2 includes a transfer member 21 and a cutting member 22. The transfer member 21 can drive the uncut tab 201 to move towards the cutting member 22. The cutting member 22 is used to cut the uncut tab 201. The transfer member 21 can also move the cut tab 202 from the cutting member 22 to the welding position. That is, the feeding of the uncut tab 201 and the transfer of the cut tab 202 can be realized through the transfer member 21, which effectively reduces the number of components, reduces the operation difficulty, and at the same time is beneficial to improve the welding efficiency of the battery pole piece tab welding device.
[0050] Specifically, with reference to Figure 1 and Figure 2 , the transfer member 21 is arranged at intervals with the cutting member 22 along the conveying direction of the conveying belt 11. The transfer member 21 and the cutting member 22 are located on the side of the positioning member 12 with the avoiding opening, so as to facilitate the transfer member 21 to transfer the tab cut by the cutting member 22 to the welding position and welded by the welding assembly 3.
[0051] Further specifically, the transfer member 21 includes a transfer clamp jaw 211, which can move perpendicular to the conveying direction of the conveying belt 11 to clamp and drive the uncut tab 201 to approach the cutting member 22, so that the cutting member 22 cuts the uncut tab 201. The transfer member 21 can also clamp and drive the cut tab 202 to move from the cutting member 22 to the welding position, so that the cut tab 202 is aligned with the pole piece 100 on the positioning member 12, facilitating the welding of the welding assembly 3.
[0052] In the embodiment, the feeding direction of the uncut tab 201 is perpendicular to the conveying direction of the conveying belt 11, that is, the extension direction of the cut tab 202 is perpendicular to the conveying direction of the conveying belt 11. Meanwhile, the extension direction of the pole piece 100 is perpendicular to the conveying direction of the conveying belt 11, and the extension direction of the pole piece 100 is parallel to the extension direction of the cut tab 202. The transfer member 21 only needs to complete the translation of the cut tab 202 to align the cut tab 202 with the pole piece 100, effectively reducing the operation difficulty and ensuring the precision during welding.
[0053] Optionally, continuing to refer to Figure 1 and Figure 2 The transfer member 21 further comprises a first driver 212, a support plate 213, a mounting plate 214, a second driver 215, a fourth driver 216 and a controller 217. The second driver 215 and the transfer clamp jaw 211 are both arranged on the mounting plate 214, and the second driver 215 can drive the clamping end of the transfer clamp jaw 211 to clamp or release. The mounting plate 214 and the fourth driver 216 are both arranged on the support plate 213, and the fourth driver 216 is used to drive the mounting plate 214 to slide up and down along the height direction of the support plate 213. The support plate 213 is connected to the output end of the first driver 212, and the output end of the first driver 212 drives the support plate 213 to move perpendicular to the conveying direction of the conveying belt 11 or parallel to the conveying direction of the conveying belt 11, thereby driving the mounting plate 214 and the transfer clamp jaw 211 on the support plate 213 to move. The controller 217 is communicatively connected to the first driver 212 and is used to control the action of the first driver 212. In the embodiment, the second driver 215 and the fourth driver 216 can both be selected as air cylinders, the first driver 212 is a motor, and the controller 217 is a PLC controller 217. After the transfer clamp jaw 211 clamps the cut tab 202, the controller 217 can control the first driver 212 to act, thereby realizing the automatic correction of the positions of the support plate 213 and the transfer clamp jaw 211, which is prior art and will not be described herein.
[0054] More specifically, as Figure 3 shown, the cutting member 22 comprises a cutter 221, a pad 222 and a pressing driving member 223. The pad 222 is arranged on one side of the conveying belt 11 in a spaced manner, and the uncut tab 201 can move along the direction perpendicular to the conveying direction of the conveying belt 11 under the driving of the transfer member 21 and be placed on the pad 222. The pad 222 is used to support and position the uncut tab 201. The cutter 221 is arranged above the pad 222, and the pressing driving member 223 is connected to the cutter 221 and is used to drive the cutter 221 to descend to cut the uncut tab 201. Exemplarily, the pressing driving member 223 can be selected as an air cylinder.
[0055] Optionally, the cutting member 22 further comprises a taking clamp 224. The taking clamp 224 is located between the cushion block 222 and the conveying belt 11, and can clamp or release the to-be-cut part of the uncut tab 201. After the uncut tab 201 is placed on the cushion block 222, the uncut tab 201 can be fixed by clamping the to-be-cut part by the taking clamp 224, so as to prevent the uncut tab 201 from deviating when the cutter 221 falls, thereby causing cutting error. At the same time, the to-be-cut part clamped by the taking clamp 224 becomes the cut tab 202 after the cutter 221 cuts, and the taking clamp 224 can prevent the cut tab 202 from falling.
[0056] Optionally, the cutting member 22 further comprises a carrier block 225 and a third driver 226. The carrier block 225 is arranged between the cushion block 222 and the conveying belt 11, the taking clamp 224 is arranged on the carrier block 225, and the third driver 226 is connected with the carrier block 225 and used to drive the carrier block 225 to ascend, so as to drive the taking clamp 224 to clamp the to-be-cut part of the uncut tab 201. In the embodiment, the third driver 226 can be a pneumatic cylinder. The pneumatic cylinder drives the carrier block 225 to ascend and descend, so as to realize the ascending and descending of the taking clamp 224.
[0057] Optionally, the cutting member 22 further comprises a fifth driver 227, which is connected with the taking clamp 224 and used to drive the clamping or releasing of the clamping end of the taking clamp 224. The fifth driver 227 can also be a pneumatic cylinder, which applies negative pressure to a sliding block arranged behind the taking clamp 224, so as to drive the taking clamp 224 to clamp the left and right sides of the uncut tab 201.
[0058] In the embodiment, the cutting assembly 2 is used to cut the uncut tab 201 and transfer the cut tab 202. The first driver 212 drives the transfer gripper 211 to move to the uncut tab 201 outside the cutter 221 according to the controller 217, the fourth driver 216 drives the transfer gripper 211 to descend, and the second driver 215 drives the transfer gripper 211 to clamp the uncut tab 201. The first driver 212 drives the transfer gripper 211 to clamp and move the uncut tab 201 forward by 20 mm (the length of the tab to be cut, i.e. the length of the cut tab 202, which can be determined according to actual needs, and is not limited here), and the second driver 215 drives the transfer gripper 211 to release the uncut tab 201 and reset. The third driver 226 drives the material taking gripper 224 and the carrier block 225 to move upward to contact the part of the uncut tab 201 to be cut, and the fifth driver 227 drives the material taking gripper 224 to clamp the part of the uncut tab 201 to be cut.

The fifth driver 227 releases the material taking gripper 224, and the third driver 226 drives the material taking gripper 224 and the carrier block 225 to retreat. The first driver 212 drives the transfer gripper 211 and the clamped cut tab 202 to move to the welding position of the tab sheet 100 according to the controller 217.
[0059] With reference to the foregoing Figure 1 and Figure 4 continuously, the welding assembly 3 comprises a welding machine table 31, an upper welding head 32, a lower welding seat 33, a first driving member 34 and an ultrasonic welding machine 35. The welding machine table 31 is arranged on the side of the conveying belt 11, the upper welding head 32 and the lower welding seat 33 are arranged on the welding machine table 31, and the distance between the upper welding head 32 and the lower welding seat 33 is adjustable. The first driving member 34 is connected with the welding machine table 31 and used to drive the welding machine table 31 to ascend, so that the lower welding seat 33 is in contact with the tab sheet 100 at the welding position. The ultrasonic welding machine 35 is arranged on the welding machine table 31 and connected with the upper welding head 32.

Specifically, the third driving member 36 can be selected as an air cylinder, and the output end of the air cylinder is connected with the upper welding head 32, so as to drive the upper welding head 32 to act.
[0061] In this embodiment, the welding assembly 3 is used to weld the cut tab 202 to the electrode 100. When the conveyor belt 11 transports the positioning member 12 and the electrode 100 to the welding position, and the transfer member 21 moves the cut tab 202 to the welding position, the welding machine 31 is driven upwards by the first drive member 34 until the lower welding seat 33 abuts against the bottom of the electrode 100. Then, the upper welding head 32, driven by the third drive member 36, descends until it presses against the top of the cut tab 202. Finally, the ultrasonic welding machine 35 is started, and high-frequency vibration and friction generate heat to melt the contact surface between the battery electrode 100 and the cut tab 202, completing the welding operation of the battery electrode tab.

The dust removal component 4 can be a blower or other air blowing device, which is existing technology, and its structure and principle will not be described in detail in this embodiment.
[0063] The operation steps of the battery electrode tab welding device provided in this embodiment are as follows:
[0064] In the first step, the second drive unit 13 is activated, causing the transmission wheel 14 to rotate clockwise, which drives the conveyor belt 11 forward.

The first drive unit 212 is activated, causing the transfer gripper 211 to move with the controller 217 to the uncut electrode tab 201 outside the cutter 221. The fourth drive unit 216 causes the transfer gripper 211 to descend, and the second drive unit 215 causes the transfer gripper 211 to clamp the uncut electrode tab 201. The first drive unit 212 causes the transfer gripper 211 to clamp and move the uncut electrode tab 201 forward by 20mm, and the second drive unit 215 causes the transfer gripper 211 to release the uncut electrode tab 201 and then return to its original position.
