Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery material stacking devices face challenges in stacking battery materials at high speeds in a sequential manner.
Innovation Solution
A battery material stacking device is designed with a conveyance mechanism, a rotor, holding portions, and a stacking table, where the rotor rotates and reverses the workpieces for sequential stacking, allowing for high-speed stacking by holding one surface with the conveyance mechanism and rotating to stack the other surface on the table, with features like cam mechanisms for precise control and imaging for accurate positioning.

Engineering Contradiction Analysis
1Productivity
If conventional stacking apparatuses are used to stack battery materials, then the stacking process can be performed, but the stacking speed is low and high-speed sequential stacking is difficult to achieve
Solution Approach 1:
The stacking apparatus is divided into multiple independent stacking units (first stacking unit, second stacking unit, etc.), each capable of stacking workpieces independently. This segmentation allows parallel operation of multiple stacking units, significantly increasing the overall stacking speed and productivity while reducing the time loss for sequential stacking.
Solution Approach 2:
The stacking units are designed to operate continuously without interruption. The rotor rotates continuously to convey workpieces, and multiple stacking units can stack workpieces in sequence without stopping the rotational conveyance. This continuous operation eliminates idle time between stacking operations and maintains constant productivity.
2Manufacturing precision
If alignment stages move and rotate to adjust electrode positions, then proper positioning is achieved, but the stacking process becomes complex and slow
Solution Approach 1:
Instead of moving and rotating alignment stages to position workpieces, the invention inverts the approach by using a rotating rotor to convey workpieces to predetermined positions. The stacking units remain stationary while the rotor rotates to deliver workpieces, simplifying the mechanism while maintaining positioning accuracy through rotational control.
Solution Approach 2:
The rotor serves multiple functions: it conveys workpieces from the conveyance mechanism, positions them at predetermined locations, and delivers them to different stacking units. This multi-functional design eliminates the need for separate alignment stages and positioning mechanisms, reducing device complexity while maintaining manufacturing precision.
3Manufacturing precision
If gas blowing units are used to blow gas against electrodes after they contact stop portions, then electrode positioning is improved, but the stacking speed is reduced
Solution Approach 1:
The rotor conveys workpieces to predetermined positions before they reach the stacking units, performing the positioning action in advance. This preliminary positioning eliminates the need for gas blowing or other corrective actions during stacking, maintaining both high precision and high speed by preparing workpieces for immediate stacking upon arrival at the stacking units.

AI summary
A battery material stacking device sequentially stacks sheet-like workpieces pertaining to a battery material at high speed. The battery material stacking device is provided with a conveyance mechanism configured to convey workpieces in a predetermined direction, a rotor arranged below the conveyance mechanism to rotate about a predetermined rotation shaft, a plurality of holding portions provided on a peripheral portion of the rotor to hold the workpieces, and a stacking table configured to stack the workpieces thereon. The plurality of holding portions is configured to hold one surface of each of the workpieces which is being conveyed with the other surface of each of the workpieces being held by the conveyance mechanism, then convey the workpieces in accordance with a rotation of the rotor while reversing the workpieces, and stack the workpieces on the stacking table with the other surface facing the stacking table.
