It should be understood that the specific embodiments described herein are only used to explain the application, and are not used to limit the application.
如图1至图8所示,本申请提供一种极片送料装置10,设置于卷绕机的机架面板1上,其包括夹料机构2、剪刀机构3、夹料移送装置4、测长装置40、剪刀移送装置6及控制器。夹料机构2滑动设置在机架面板1上,用于在卷绕机中将极片料带传送到卷绕机构50;剪刀机构3设置于机架面板1上,用于剪断极片料带;夹料移送装置4用于驱动夹料机构2在机架面板1上滑动,夹料机构2夹紧极片料带时,夹料移送装置4驱动夹料机构2将极片料带送入卷绕机构50,夹料机构2松开极片料带时,夹料移送装置4驱动夹料机构2复位;测长装置40用于测量进入卷绕机构50的极片料带的长度,并将测量信号发送至控制器;剪刀移送装置6用于驱动剪刀机构3运动;控制器(图中未示出)与测长装置40、夹料移送装置4以及剪刀移送装置6电连接,当测长装置40检测到进入卷绕机构50的极片料带达到预定值时,控制器控制剪刀移送装置6在预定位置将极片料带剪断。As shown in FIG. 1 to FIG. 8, the present application provides a pole piece feeding device 10, which is arranged on a frame panel 1 of a winding machine and includes a clamping mechanism 2, a scissors mechanism 3, a clamping transfer device 4, and a measuring device. Long device 40, scissors transfer device 6, and controller. The clamping mechanism 2 is slidably disposed on the frame panel 1 for transferring the pole piece material tape to the winding mechanism 50 in the winding machine; the scissors mechanism 3 is disposed on the frame panel 1 for cutting the pole piece material tape ; The gripping and transferring device 4 is used to drive the gripping mechanism 2 to slide on the rack panel 1. When the gripping mechanism 2 clamps the pole piece tape, the gripping and transferring device 4 drives the gripping mechanism 2 to feed the pole piece into Winding mechanism 50. When the clamping mechanism 2 releases the pole piece tape, the clamping transfer device 4 drives the clamping mechanism 2 to reset; the length measuring device 40 is used to measure the length of the pole piece tape entering the winding mechanism 50, and Send the measurement signal to the controller; the scissors transfer device 6 is used to drive the movement of the scissors mechanism 3; the controller (not shown in the figure) is electrically connected to the length measuring device 40, the clamp transfer device 4 and the scissors transfer device 6, When the long device 40 detects that the pole piece tape entering the winding mechanism 50 reaches a predetermined value, the controller controls the scissors transfer device 6 to cut the pole piece tape at a predetermined position.
卷绕机工作之前,可以根据卷绕需要设定剪刀移送装置驱动剪刀机构运动的行程L。具体的,可以通过剪刀移送装置的工作时间或运动行程等来实现。例如,若剪刀移送装置为电机-丝杠机构时,可以控制电机的工作时间来控制剪刀机构运动的行程;若剪刀移送装置为气缸或油缸等,则可以通过控制气缸或油缸的运动行程来设定剪刀机构运动的行程。假设正极片送料装置的剪刀机构的运动行程为L1,负极片送料装置的剪刀机构的运动行程为L2,若正、负极片送料装置的剪刀机构同时开始同向运动,然后同时将极片料带剪断,那么,L1与L2的差值即为正、负极片的尾卷长度的差值。若要实现负极外包,可将L1设置为0,即正极片送料装置的剪刀机构的位置不变,然后负极片送料装置的剪刀机构向极片传送方向相反的方向逆向运动L2,那么,L2即为正、负极片的尾卷长度的差值。Before the winding machine works, the stroke L for driving the scissors mechanism to move by the scissors transfer device can be set according to the winding needs. Specifically, it can be achieved by the working time or the movement stroke of the scissors transfer device. For example, if the scissors transfer device is a motor-screw mechanism, the working time of the motor can be controlled to control the stroke of the scissors mechanism movement; if the scissors transfer device is an air cylinder or oil cylinder, it can be set by controlling the movement stroke of the air cylinder or oil cylinder. Set the stroke of the scissors mechanism movement. Assume that the movement of the scissors mechanism of the positive electrode feeding device is L1, and the movement of the scissors mechanism of the negative electrode feeding device is L2. If the scissors mechanisms of the positive and negative electrode feeding devices start to move in the same direction at the same time, then simultaneously Shearing, then, the difference between L1 and L2 is the difference between the length of the tail roll of the positive and negative plates. To achieve the negative electrode outsourcing, L1 can be set to 0, that is, the position of the scissors mechanism of the positive electrode sheet feeding device does not change, and then the scissors mechanism of the negative electrode sheet feeding device moves in the opposite direction to the opposite direction of the electrode sheet L2. Then, L2 is It is the difference between the length of the tail roll of the positive and negative plates.
下面以正极片送料装置的剪刀机构的位置保持不变,仅负极片送料装置的剪刀机构运动的情况为例,对本申请的极片送料装置的工作过程作进一步说明。应当说明的是,本工作过程说明并不对本申请作限制。实际工作过程中,正极片送料装置的剪刀机构也可以运动,L1与L2的具体数值根据实际工作需要设定即可。In the following, the position of the scissors mechanism of the positive electrode sheet feeding device remains unchanged, and only the case where the scissors mechanism of the negative electrode sheet feeding device moves is used as an example to further explain the working process of the electrode sheet feeding device of the present application. It should be noted that this working process description does not limit this application. In the actual working process, the scissors mechanism of the positive electrode sheet feeding device can also move, and the specific values of L1 and L2 can be set according to the actual working needs.
当卷绕机开始工作时,夹料机构2将极片料带夹紧,夹料移送装置4驱动夹料机构2运动至如图6所示的位置,以将极片料带送入卷绕机的卷绕机构50的第一工位,极片料带与隔膜在第一工位上开始卷绕,在测长装置40检测到送入第一工位的极片料带的长度达到预定值(根据电芯需要的卷绕长度设定)时,控制器接收测长装置40发送的信号,控制负极片送料装置的剪刀移送装置6运动L2,在如图7所示的预定位置将极片料带剪断,以调整尾卷极片的长度,使得负极片的尾卷长度比正极片的尾卷长度长L2。可以理解的,为了使极片送料装置能实现持续送料,在剪刀机构3向上运动的同时,夹料移送装置4也可以驱动夹料机构2向上运动。以使得在剪刀机构3剪断极片料带时,剪刀机构3与夹料机构2之间的极片料带的长度与夹料机构2处于送料初始位置时二者之间的极片料带的长度相同。When the winding machine starts to work, the clamping mechanism 2 clamps the pole piece tape, and the clamping transfer device 4 drives the clamping mechanism 2 to the position shown in FIG. 6 to feed the pole piece tape into the winding. At the first station of the winding mechanism 50 of the machine, the pole piece tape and the diaphragm start winding at the first station, and the length measuring device 40 detects that the length of the pole piece tape sent to the first station reaches a predetermined length. When the value is set according to the winding length required by the battery cell, the controller receives the signal sent by the length measuring device 40, controls the scissors transfer device 6 of the negative piece feeding device to move L2, and moves the pole at a predetermined position as shown in FIG. The sheet tape is cut to adjust the length of the tail roll electrode sheet, so that the tail roll length of the negative electrode sheet is longer than the tail roll length of the positive electrode sheet by L2. It can be understood that, in order to enable the pole piece feeding device to achieve continuous feeding, while the scissors mechanism 3 moves upward, the clamping transfer device 4 can also drive the clamping mechanism 2 to move upward. So that when the pole piece tape is cut by the scissors mechanism 3, the length of the pole piece tape between the scissors mechanism 3 and the gripping mechanism 2 and the length of the pole piece tape between the two when the gripping mechanism 2 is in the initial feeding position The same length.
优选地,如图1所示,剪刀移送装置6设置于机架面板1上,剪刀移送装置6的移动端与送料底座5连接,剪刀移送装置6可驱动送料底座5在机架面板1上滑动。夹料机构2、夹料移送装置4及剪刀机构3设置于送料底座5上,夹料移送装置4可驱动夹料机构2在送料底座5上滑动。Preferably, as shown in FIG. 1, the scissors transfer device 6 is disposed on the rack panel 1, the moving end of the scissors transfer device 6 is connected to the feeding base 5, and the scissors transfer device 6 can drive the feeding base 5 to slide on the rack panel 1. . The gripping mechanism 2, the gripping and transferring device 4 and the scissors mechanism 3 are disposed on the feeding base 5. The gripping and transferring device 4 can drive the gripping mechanism 2 to slide on the feeding base 5.
具体地,夹料机构2复位后,当测长装置40检测到进入到卷绕机构50的极片料带的长度到达预定值时,控制器控制剪刀移送装置6工作,以驱动送料底座5向上运动,使剪刀机构3在预定位置将极片料带剪断,以增加极片的尾卷长度。由于夹料机构2、夹料移送装置4及剪刀机构3均设置于送料底座5上,当剪刀机构3运动时,夹料机构2同步运动。剪断极片料带后,剪刀移送装置6驱动送料底座5向下运动,以将夹料机构2与剪刀机构3回复到送料的初始位置,从而进行下一次送料。Specifically, after the clamping mechanism 2 is reset, when the length measuring device 40 detects that the length of the pole piece tape entering the winding mechanism 50 reaches a predetermined value, the controller controls the scissors transfer device 6 to work to drive the feeding base 5 upward. The movement causes the scissors mechanism 3 to cut the pole piece strip at a predetermined position to increase the length of the tail roll of the pole piece. Since the clamp mechanism 2, the clamp transfer device 4, and the scissors mechanism 3 are all disposed on the feeding base 5, when the scissors mechanism 3 moves, the clamp mechanism 2 moves synchronously. After the pole pieces are cut, the scissors transfer device 6 drives the feeding base 5 to move downward to return the clamping mechanism 2 and the scissors mechanism 3 to the initial position of the feeding, so as to perform the next feeding.
优选地,为加快效率,在剪刀机构3向下运动复位时,夹料驱动装置22同时驱动夹料机构2在送料底座5上滑动。这样,在剪刀机构3回复在初始位置时,夹料机构2也同时将极片送入到卷绕机构50,可以提高卷绕效率。Preferably, in order to speed up the efficiency, when the downward movement of the scissors mechanism 3 is reset, the gripping driving device 22 simultaneously drives the gripping mechanism 2 to slide on the feeding base 5. In this way, when the scissors mechanism 3 returns to the initial position, the chucking mechanism 2 also feeds the pole pieces to the winding mechanism 50 at the same time, which can improve the winding efficiency.
