Problems solved by technology

When the battery core after winding is separated from the winding needle, the internal space of the battery core is in a free state, and the unloading manipulator realizes automatic unloading without positioning control, and the battery core will shrink and deform into the internal space. , the deformation has a certain impact on the position of the tab, and at the same time produces a certain displacement on the pole piece, which reduces the quality of the cell

Embodiment Construction

[0033] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] Such as Figure 1~Figure 9 As shown, the battery blanking and forming device of the present invention includes a blanking movable platform 1 and a locking mechanism arranged on the blanking movable platform 1 for positioning the bare battery 100. The locking mechanism includes a lower positioning mechanism 2 and an upper positioning mechanism 2. Positioning mechanism3.

[0035] The blanking movable platform 1 is arranged under the rolling needle 100, the axis of the rolling needle 100 extends along the front and back directions (the Z direction shown in the figure), and the blanking movable platform 1 can move along the left and right directions (the X direction shown in the figure) and up and down direction (Y direction shown in the figure), the lower positioning mechanism 2 is used to position the lower part of the inside of the bare...

Abstract

The invention discloses a device and a method for discharging and forming cells. A bare cell is wound on a winding needle. The device for discharging and forming the cells comprises a discharge movable platform and a locking mechanism. The locking mechanism is used for positioning the bare cell and comprises a lower positioning mechanism and an upper positioning mechanism, the lower positioning mechanism is used for positioning the lower portion of the inside of the bare cell, the upper positioning mechanism is used for positioning the upper portion, which is opposite to the lower portion, ofthe bare cell, and the upper positioning mechanism and the lower positioning mechanism are movably arranged on the discharge movable platform. The device and the method for discharging and forming thecells have the advantages that the device is simple in structure, the cells can be accurately positioned and controlled when automatically discharged, contraction deformation of the cells towards internal spaces of the cells can be prevented, accordingly, the purpose of controlling pole pieces to prevent displacement can be achieved, and the quality of the cells can be improved.

Description

technical field [0001] The invention relates to the technical field of battery production and manufacturing, in particular to a battery blanking and forming device and a battery blanking and forming method. Background technique [0002] In the field of domestic battery manufacturing, the battery cell includes a diaphragm and a pole piece, and the pole piece and the diaphragm are wound into a diamond-shaped battery core by using a diamond-shaped rolling needle. When the battery core after winding is separated from the winding needle, the internal space of the battery core is in a free state, and the unloading manipulator realizes automatic unloading without positioning control, and the battery core will shrink and deform into the internal space. , the deformation has a certain impact on the position of the tab, and at the same time produces a certain displacement on the pole piece, which reduces the quality of the cell. Contents of the invention [0003] The object of ...
