Description
Technical Field
[0001] The utility model relates to the technical field of lithium battery production, in particular to a pole ear insertion device capable of maintaining a consistent depth. Background Art
[0002] The tab is a raw material for lithium-ion polymer battery products. Since the use of lithium batteries relies on the tab to transmit current, the tab is usually installed inside the battery by plugging. The tab is thin, and it needs to remain flat during plugging. This requires a tab insertion device that can maintain a consistent depth. Therefore, the existing tab insertion device that can maintain a consistent depth has been continuously innovated and developed. It can be seen that the current tab insertion device that can maintain a consistent depth basically meets people's needs, but there are still some problems.
[0003] The existing tab insertion device usually clamps the rolled tab by a clamping arm or a roller and directly inserts the tab into the lithium battery.
[0004] However, when the existing device is plugging the pole ear, since the pole ear is rolled up in the storage tray before plugging, wrinkles are inevitable on its surface when the pole ear is taken out. At this time, if the pole ear is directly inserted into the battery, it is inevitable that it will bend and break, and the insertion depth of the pole ear in the lithium battery will be inconsistent. Therefore, there is an urgent need for a pole ear insertion device that can maintain a consistent depth to solve the above problems. Utility Model Content

[0027] When using a tab insertion device that can maintain consistent depth, first install the storage tray 4 with the tab rolled up on the surface of the connecting rod 3, then place one end of the tab between the two groups of extrusion plates 13, raise the damper 11 and the first return spring 12 to push the extrusion plate 13 to move, so that the two groups of extrusion plates 13 clamp the tab, then connect the servo motor 5 to the power supply, the output end of the servo motor 5 drives the first transmission rod 6 to rotate, the rotation engagement of the first transmission rod 6 drives the transmission block 7 to rotate, the rotation of the transmission block 7 drives the second transmission rod 9 to rotate through the transmission belt 8, the first transmission rod 6 rotates clockwise, and the second transmission rod 9 rotates counterclockwise, thereby driving the surface extrusion plate 13 to move relative, the extrusion plate 13 clamps the tab by relative movement, and when inserting the tab, the movement of the tab drives the storage tray 4 to rotate, thereby inserting the tab in the storage tray 4 into the battery.
