Description

Secondary battery high-speed cell stacking apparatus {Secondary cell stacking apparatus}

The present invention relates to a high-speed cell stacking device for secondary batteries. More specifically, the problem of tension unevenness of the separator can be effectively solved by preventing reverse movement of the separator, thereby improving cell quality of secondary batteries. This relates to a secondary battery high-speed cell stacking device that can contribute to.

A secondary cell (also known as a secondary battery) converts chemical energy into electrical energy and supplies power to an external circuit. When discharged, it receives external power and converts electrical energy into chemical energy to store electricity. refers to a battery that can Secondary batteries are also commonly called capacitors.

These secondary batteries can be classified in various ways depending on the structure of the electrode assembly. For example, secondary batteries can be classified into a stack-type structure, a wound-type (jelly roll-type) structure, and a stacked/folding-type structure.

Among various classifications, the stacked structure refers to forming an electrode assembly, or cell, by sequentially stacking an anode, a separator, and a cathode. At this time, a separator is placed between the anode and the cathode, and a secondary battery high-speed cell stacking device is used for this stacking process.

Meanwhile, maintaining the tension of the separator during cell stacking is a very important factor that determines the quality of cells, which are stacking products. In other words, in the cell stacking process of stacking the separator over the anode, placing the cathode, stacking the separator over the cathode, and then placing the anode again, the tension maintenance technology of the separator interposed in the middle has a significant impact on cell quality.

However, in the case of existing technology, the stacking process has been carried out in the order of anode, separator, cathode, separator, anode, etc. by simply tilting the stacking stage by moving it left and right. Due to its structural limitations, the stacking stage There is a high possibility that the length of the separator will change depending on the section in which it moves.

To elaborate, when the stacking stage is moved, for example, from the anode stacking position to the correct position and then moves to the cathode stacking position, or vice versa, a phenomenon occurs in which the separator moves in the reverse direction, that is, in the direction opposite to the direction in which the separator is supplied to the stacking stage. This change in the length of the separator can cause uneven tension in the separator, which can reduce cell quality.

In order to solve the problem of uneven tension of the separator, it may be considered to apply a dancer mechanism to the separator feeder, but it is not easy to solve the conventional problem simply by applying the dancer mechanism. In particular, considering that the problem of non-uniform tension in the separator is bound to become more severe when the stacking stage is driven at high speed, there is a need for technology development to solve this problem.

A plurality of grippers 131 are disposed around the stacking stage 140 to prevent the electrodes stacked on the stacking stage 140 from being disturbed.

That is, the stacking stage 140 performs a tilting operation as shown in FIGS. 4 to 8, and a plurality of grippers 131 are provided to prevent the anode, cathode, or separator already stacked on the stacking stage 140 from being disturbed during this tilting operation. . In other words, the gripper 131 is disposed around the stacking stage 140 and serves to grip one of the anode, separator, and cathode stacked on the stacking stage 140.

A cylinder 132 is connected to the gripper 131. The cylinder 132 serves to provide uniform pressure when the gripper 131 grips one of the anode, separator, and cathode.

And, the gripper moving part 133 is connected to the grippers 131. The gripper moving unit 133 is connected to the grippers 131 and serves to move the grippers 131 one to another. The gripper moving part 133 may be applied in a structure such as a motor and a ball screw.

A stacking up/down driving unit 144 is connected to the stacking stage 140. The stacking up/down driving unit 144, which can be applied as a motor and ball screw structure, is connected to the stacking stage 140, and when the anode, separator, and cathode are stacked one by one on the stacking stage 140, the stacking stage 140 ) plays a role in gradually driving down. For example, when one anode is stacked on the stacking stage 140, the stacking stage 140 is lowered by the action of the stacking up/down driver 144 by the thickness of one anode, and then the cathode is turned down by one cathode. When stacked, the stacking stage 140 can be moved down by the action of the stacking up/down driver 144 by the thickness of one cathode sheet.

The stage tilting driver 150 is connected to the stacking stage 140 as shown in FIGS. 4 to 8 and serves to drive the stacking stage 140 to tilt.

This stage tilting driver 150 is connected to the stage rotation axis 151 that is connected to the stacking stage 140 and forms the rotation axis of the stacking stage 140, and to one end of the stage rotation axis 151, and the stage rotation axis 151 A tilting motor 152 that generates power for rotation, and a rotation support module 153 that is connected to the stage rotation axis 151 on the opposite side of the tilting motor 152 and rotatably supports the stage rotation axis 151 at the corresponding position. ) may include.

Accordingly, when the tilting motor 152 is driven to rotate the stage rotation axis 151 clockwise or counterclockwise, the stacking stage 140 is linked to the anode stacking unit 110 or the cathode stacking unit ( It can be tilted toward 120).

The stage up/down driver 160 is connected to the stacking stage 140 and the stage tilting driver 150, and the stacking stage 140 and the stage tilting driver 150 are used to prevent reverse movement of the separator when the stacking process progresses. It serves to selectively drive up/down.

These stage up/down driving units 160 integrally support a plurality of fixed posts 161, the stacking stage 140, and the stage tilting driving unit 150, which are arranged spaced apart from each other and fixed at the corresponding positions, while both sides have a plurality of An up/down beam (162) connected up/down to the fixed post 161, an up/down ball screw (163) connected to the up/down beam (162), , an up/down motor 164 that is connected to the up/down ball screw 163 and generates power to move the up/down beam 162 up/down via the up/down ball screw 163, It is connected to the fixed post 161 and the up/down beam 162, and an up/down LM guide ( 165).

That is, after the anode is stacked on the stacking stage 140 through interaction with the anode stacking unit 110 as shown in FIG. 4, the separator is stacked on the anode and the stacking stage 140 moves toward the cathode stacking unit 120 as shown in FIG. 5. When tilting, the separator has no choice but to move in reverse in response to the operation of the stacking stage 140. However, in the case of this embodiment, when the stacking stage 140 tilts toward the cathode stacking unit 120 as shown in FIG. 5, the stacking stage 140 and the stage tilting driving unit ( 150) operates down to prevent reverse movement of the separator. Therefore, it is possible to effectively solve the problem of non-uniform tension of the separator.

Meanwhile, as mentioned above, the secondary battery high-speed cell stacking device according to this embodiment is further equipped with a device controller 190 to control the device.

The device controller 190 is connected to the cell stacking unit 130 and controls the operation of the cell stacking unit 130 through an organic mechanism so that cells are manufactured on the stacking stage 140.

In other words, the device controller 190 controls the stacking stage 140 when the stacking stage 140 moves between the anode stacking position where the anode is stacked and the cathode stacking position where the cathode is stacked, that is, when operating as shown in FIGS. 4 to 8. ) controls the operation of the stage up/down driver 160 to go up/down.

This control can effectively solve the problem of non-uniform tension of the separator by preventing reverse movement of the separator, that is, moving to the upper part of the pictures in Figures 4 to 8, which will contribute to improving the cell quality of secondary batteries. It becomes possible.
