In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present invention.
As shown in fig. 1 to 2, an embodiment of the present invention provides a scrap winding mechanism installed on a battery cell production device for winding sheared pole piece scraps on a pole piece conveying path, which comprises a winding needle seat 1, a winding needle assembly 2, a clamping device 3 and a winding device 4, wherein the winding needle assembly 2 is rotatably arranged on the winding needle seat 1, the clamping device 3 is used for driving the winding needle assembly 2 to clamp the pole piece scraps, and the winding device 4 is used for driving the winding needle assembly 2 to rotate so as to wind the pole piece scraps on the winding needle assembly 2.
In an embodiment, as shown in fig. 1 to 2, the waste winding mechanism further includes a mounting base 5, a slide rail driving device 6, a slide rail 7, and a slider 8 matched with the slide rail 7, wherein the mounting base 5 is used for mounting the waste winding mechanism on a battery cell production device, the slide rail driving device 6 and the slider 8 are fixed on the mounting base 5, the slide rail 7 is fixedly connected with the moving end of the slide rail driving device 6, the needle winding seat 1 is fixed on the slide rail 7, and the slide rail driving device 6 can drive the slide rail 7 and the needle winding seat 1 to move on the slider 8.
When the battery cell production equipment detects the pole piece scraps, the slide rail driving device 6 drives the slide rail 7 to move so that the winding needle assembly 2 is positioned on the pole piece conveying path. Then, the pole piece waste materials are sent into the winding needle assembly 2 for winding by the pole piece feeding device of the battery cell production equipment. After winding is completed, the pole piece waste materials are sheared from the pole piece material belt by a scissor mechanism of the pole piece feeding device. Finally, the slide rail driving device 6 drives the slide rail 7 to reset so as to remove the pole piece scrap coil, and the pole piece material belt after the pole piece scrap is removed is continuously sent to the triangular winding head for winding by the pole piece feeding device. After the slide rail 7 resets, the pole piece waste coil can be manually taken down from the coil needle assembly 2 by a worker, and a mechanism for automatically taking down the pole piece waste coil from the coil needle assembly 2 can be additionally arranged. Therefore, the pole piece material belt is always conveyed in a normal state, and even if pole piece scraps appear, the pole piece material belt does not need to be stopped. In addition, the scrap winding mechanism resets after winding the scrap of the pole piece, and the pole piece material belt after removing the scrap of the pole piece can continuously transmit to the triangular winding head when taking down the scrap of the pole piece from the winding needle assembly 2, so that the time occupied by removing the scrap of the pole piece is reduced, and the winding efficiency of the battery cell can be improved. The battery cell production equipment adopting the waste winding mechanism of the embodiment is characterized in that the two waste winding mechanisms are respectively positioned between the positive plate feeding device and the triangular winding head, and between the negative plate feeding device and the triangular winding head. When the cell production equipment detects the occurrence of pole piece scraps, the controller controls one scrap winding mechanism to move onto the pole piece conveying path, and the other scrap winding mechanism is kept motionless. Then, the positive and negative electrode sheet feeding devices respectively feed the positive and negative electrode sheets into a scrap winding mechanism on the electrode sheet conveying path for winding. Meanwhile, the controller controls the first station of the triangular winding head to temporarily stop working, namely temporarily stop winding the diaphragm. When the winding of the pole piece scraps is completed, the scraps winding mechanism is reset, and the winding material is continuously sent into the triangular winding head for winding. By arranging the two waste winding mechanisms, the two waste winding mechanisms can work alternately, and the continuity of the whole machine work is improved.
Preferably, the scrap winding mechanism winds the pole piece scrap on the winding needle assembly thereof within the time that the scissors mechanism of the pole piece feeding device shears the pole piece material strip twice. Therefore, when the pole piece detecting device detects the pole piece scraps, the pole piece feeding device still feeds and shears the pole piece material belt according to the state when the pole piece scraps are not detected, and the automation degree of the battery cell production equipment is improved.
It should be noted that in other embodiments, the scrap winding mechanism may also be fixedly disposed on the pole piece transport path. When the detecting device of the battery cell production equipment does not detect the pole piece waste, the pole piece feeding device feeds the pole piece material belt to the triangular winding head through the winding needle assembly 2. When the battery cell production equipment detects the pole piece waste, the clamping device 3 controls the winding needle assembly 2 to clamp the pole piece waste and wind the pole piece waste on the winding needle assembly 2. After winding is completed, the pole piece waste materials are sheared from the pole piece material belt by the scissor mechanism of the pole piece feeding device, so that the pole piece waste material roll can be taken out from the winding needle assembly 2. After the pole piece waste is removed, the winding needle assembly 2 is opened, and the pole piece material belt continuously passes through the winding needle assembly 2 and is sent to the triangular winding head for winding.

When the clamping cylinder drives the moving shaft sleeve 32 to move towards the second winding needle 222, the moving shaft sleeve 32 drives the bearing mounting seat 331 to move towards the pressing surface 2211, and the outer ring surface of the winding needle clamping bearing 332 abuts against the pressing surface 2211. When the winding needle assembly 2 rotates, the bearing mounting seat 331 rotates following the winding needle assembly 2, so that the outer ring surface of the winding needle clamping bearing 332 always abuts against the pressing surface 2211 when the winding needle assembly 2 rotates, and the winding needle assembly 2 always clamps the pole piece waste when winding.
