Working method embodiments of the tab shaping and transferring device are as follows:
The invention provides a working method of a tab shaping and transferring device, which uses the tab shaping and transferring device 10 of the embodiment of the cylindrical battery core sheet-making winder to cut a tab roll, and deliver the cut tab to a tab welding device of the cylindrical battery core sheet-making winder for welding after correcting the position of the cut tab, and the working method of the tab shaping and transferring device is described as follows, and the working method comprises the following steps:
And (3) feeding:
When the tab roll is required to be cut, the traction mechanism 32 of the traction unit 3 drives the upper pressing block 322 to move towards the lower pressing block 323 by the driving mechanism 321, so that the free end of the tab roll is pressed on the lower pressing block 323, and the tab roll is pressed. Then, the guiding mechanism 31 of the traction unit 3 drives the traction mechanism 32 to slide along the guide rail 311, so that the tab roll is delivered to the shaping unit 2. During the process of delivering the tab rolls by the traction unit 2, the driving mechanism of the unreeling mechanism 9 drives the material disc 91 to rotate, and the pole piece rolls are assisted to unreel.
And (3) compacting:
When the tab roll is delivered to the shaping unit 2, the guide mechanism 31 stops driving the traction mechanism 32. The upward moving mechanism 2 of the shaping unit 2 drives the shaping mechanism 21 to roll the tab material, and meanwhile, the driving mechanism 231 of the downward pressing mechanism 23 drives the pressing block 232 to move towards the tab material roll, so that the bearing platform 212 of the shaping mechanism 21 and the pressing block 232 of the downward pressing mechanism 23 are pressed on two sides of the tab material roll to press the tab material roll, and the cut tab is prevented from moving or falling.
And cutting:
Then, the driving mechanism 41 of the cutting unit 4 controls the cutter 42 to move towards the feeding port of the shaping unit 2, so that the cutter 42 cuts the pole piece roll to form a pole lug, and after the cutter 42 finishes cutting the pole piece roll, the driving mechanism 41 controls the cutter to reset.
Shaping:
Then, the driving mechanism 213 of the shaping mechanism 21 drives the two clamping plates 214 to move towards the bearing platform 212 until the two clamping plates 214 are adjacent to the bearing platform 212, so that position correction of the cut tab is realized, and the tab and the pole piece to be welded can be kept in a mutually perpendicular state.
Transferring:
When the tab is corrected, the driving mechanism 521 of the first clamping mechanism 52 of the first clamping unit 5 drives the two first clamping jaws 522 to move relatively, so that the two first clamping jaws 522 clamp the tab. Then, the shaping unit 2 resets, thereby giving way for the delivery of the tab. Then, the driving mechanism 513 of the first guiding mechanism 51 drives the sliding base 512 to move toward the tab welding device 102 along the guide rail 511, so that the first clamping mechanism 52 mounted on the sliding base 512 moves the tab to the tab welding device 102.
While the driving mechanism 513 drives the sliding seat 512 to move, the guiding unit 8 drives the mounting seat 1 to move towards the tab welding device 102 by a fixed length by removing the driving mechanism 81, so that the position offset of the tab in the delivering process is reduced. Meanwhile, the traction unit 3 performs next feeding to the shaping unit 2, and prepares for cutting of the next tab roll, and the feeding operation of the traction unit 3 is consistent with the above working process, i.e. the above feeding steps are not repeated here.
When the tab is close to the pole piece on the tab welding device 102, the detection end of the position sensing unit 7 can acquire the position information of one end of the tab far away from the pole piece, namely the distance between the end of the tab and the edge of the pole piece, and sends the position information to the control system of the cylindrical battery core sheet-making winder. When the tab clamped by the first clamping mechanism 52 reaches the set position, the control system controls the driving mechanism 513 to stop driving the first clamping mechanism 52 according to the position information sent by the position sensing unit 7, so that the first clamping mechanism 52 stops moving, and at this time, the fixed distance between the tab end and the pole piece edge is the set position.
And (3) welding:
Next, the first downward movement mechanism 523 controls the first clamping mechanism 52 to move toward the pole piece on the tab welding device 102, so that the first clamping mechanism 52 is attached to the pole piece toward the tab. Then, the tab and the pole piece are welded by the welding head of the tab welding device 102.
When the tab welding device 102 welds the pole piece on the first clamping mechanism 52, the tab shaping and transferring device simultaneously and sequentially performs the following operations: the shaping unit 2 compresses the tab coil, namely, a compressing step; the cutting unit 4 cuts the tab material roll, namely a cutting step; the shaping unit 2 performs position correction on the cut tab of the other section, namely a shaping step, and after the position correction of the tab is completed, the driving mechanism 621 of the second clamping mechanism 62 of the second clamping unit 6 drives the two second clamping jaws 622 to clamp the tab, and then the shaping unit 2 resets; the working principle of the above operation, the working sequence is identical to the working process, and the description is not repeated here.
Resetting:
When the welding of the tabs on the first clamping unit 5 is completed, the driving mechanism 521 of the first clamping mechanism 52 drives the two first clamping jaws 522 to reset, then the driving mechanism 513 of the first guiding mechanism 51 drives the first clamping mechanism 52 to reset, and the driving mechanism 81 of the guiding unit 8 drives the mounting base 1 to reset.
The driving mechanism 613 of the second guide mechanism 61 of the second gripping unit 6 drives the second clamping mechanism 62 to move toward the tab welding device 102 while the first gripping unit 5 is reset. After the guide unit 8 drives the mounting seat 1 to reset for a certain distance, the guide unit 8 drives the mounting seat 1 to move towards the tab welding device 102 again.
In addition, when the second clamping mechanism 61 is transferred to the tab welding device 102, the traction unit 3 performs feeding again to the shaping unit 2, and prepares for cutting the tab roll again, that is, the feeding step, and the feeding operation of the traction unit 3 is consistent with the above working process, and will not be described in detail herein.
Then, when the tab is close to the pole piece on the tab welding device 102, the detection end of the position sensing unit 7 can acquire the position information of one end of the tab far away from the pole piece, namely the distance between the end of the tab and the edge of the pole piece, and send the position information to the control system of the cylindrical battery core sheet-making winder. When the tab clamped by the second clamping mechanism 62 reaches the set position, the control system controls the driving mechanism 613 to stop driving the second clamping mechanism 62 according to the position information sent by the position sensing unit 7, so that the second clamping mechanism 62 stops moving, and at this time, the fixed distance between the tab end and the pole piece edge is the set position.
Then, the second downward moving mechanism 63 controls the second clamping mechanism 62 to move towards the pole piece on the tab welding device 102, so that the second clamping mechanism 62 is attached to the pole piece towards the tab. Then, the tab and the pole piece are welded by the welding head of the tab welding device 102.
When the tab welding device 102 welds the pole piece on the second clamping mechanism 62, the tab shaping and transferring device simultaneously and sequentially performs the following operations: the shaping unit 2 compresses the tab coil, namely, a compressing step; the cutting unit 4 cuts the tab material roll, namely a cutting step; the shaping unit 2 performs position correction on the other section of the cut tab, namely a shaping step, and after the tab is subjected to position correction, the driving mechanism 521 of the first clamping mechanism 52 of the first clamping unit 5 drives the two first clamping jaws 522 to clamp the tab, and then the shaping unit 2 resets; the working principle of the above operation, the working sequence is identical to the working process, and the description is not repeated here.
When the second clamping mechanism resets, the lug shaping and conveying device executes the conveying step again; when the second clamping unit is reset, the tab shaping and transferring device executes the welding step again. That is, after the welding of the tab on the second clamping unit 6 is completed, the driving mechanism 61 of the second clamping mechanism 62 drives the two second clamping jaws 622 to reset, then the driving mechanism 613 of the second guiding mechanism 61 drives the second clamping mechanism 62 to reset, and the driving mechanism 81 of the guiding unit 8 drives the mounting base 1 to reset.
The driving mechanism 513 of the first guide mechanism 51 of the first gripping unit 5 drives the first clamping mechanism 52 to move toward the tab welding device 102 while the second gripping unit 6 is reset. After the guide unit 8 drives the mounting seat 1 to reset for a certain distance, the guide unit 8 drives the mounting seat 1 to move towards the tab welding device 102 again, so that the tab material coil is circularly cut, the tab is subjected to position correction, and the tab and the pole piece are welded.
In summary, the working method of the tab shaping and transferring device provided by the invention can realize that the tab material roll is cut into the tab, the position of the cut tab is corrected, and the tab is moved to the pole piece for welding after the position correction of the tab is completed, so that the mutual perpendicularity between the tab and the pole piece is ensured. In addition, the working method carries out alternate delivery on the lugs after the position correction of the shaping unit is completed through the two clamping units, and the production efficiency of the lug shaping and conveying device is greatly improved. The working method provided by the invention has the advantages of high processing quality, high production efficiency and capability of ensuring the perpendicularity between the pole piece and the pole lug.
