Stack manufacturing equipment for prismatic secondary batteries

Abstract

The invention provides a stack manufacturing device for a square secondary battery, which is characterized in that it includes a plate loading unit (20), has a rotating body (22) that rotates around an axis that is horizontal to the ground, and is used to clamp multiple plates. Each pole plate clamping panel (21a, 21b, ...) is attached along the periphery of the above-mentioned rotating body (22), and the above-mentioned rotating body (22) rotates to one side in the order of rotating action, stopping action, and rotating action, and In each of the above-mentioned rotation actions, it rotates at a predetermined angle of 180 degrees or less. When the above-mentioned rotating body (22) performs the above-mentioned stop action, the above-mentioned electrode plate clamping panels (21a, 21b, ...) can perform predetermined operations, and the above-mentioned The predetermined work includes the work of storing the pole plate (1) supplied from the outside of the above-mentioned rotating body (22) and the work of transferring the stored pole plate to the outside of the above-mentioned rotating body (22). The above-mentioned pole plate clamping panels at different positions are performed simultaneously.

Description

technical field [0001] The present invention relates to a device for manufacturing a battery in a prismatic secondary battery, and more particularly, to a manufacturing device for manufacturing a stack in which negative and positive plates are alternately placed on a separator. Background technique [0002] In general, a chemical battery is a battery composed of a pair of electrodes of a positive plate and a negative plate and an electrolyte, and the amount of energy that can be stored differs depending on the materials constituting the electrodes and electrolyte. This chemical battery is divided into primary battery and secondary battery. Primary battery is only used for one discharge because of its very slow charging reaction. Secondary battery can be reused by repeatedly charging and discharging. Recently, due to the Advantages, the use of secondary batteries is gradually increasing. [0003] Due to their advantages, secondary batteries have been used in various technica...

Problems solved by technology

This may cause damage to the diaphragm, so the movement speed of the stack base is limited to below the specified speed

[0016] Second, the speed of movement is limited due to the time required to correct for the "feedback phenomenon" of the diaphragm that accompanies horizontal movement of the stack base

Due to the time required for this corrective work, the horizontal movement speed of the stack base 5 is limited

[0017] Therefore, although the movement speed of the stack base can be further improved in terms of equipment performance, it cannot exceed a certain speed

[0018] In prior art 2, the link-type loading unit used to transfer the plate from the plate magazine to the alignment table takes time to return to the magazine position after transferring the plate to the alignment table, so the The loading speed is correspondingly slower

Also, when the tilt table reciprocates at a predetermined angle, the reciprocating rotation speed may be limited due to the speed limit for preventing damage to the clamped diaphragm part and the feedback phenomenon of the diaphragm described above.
