Electrode Sheet Placement Method for Stable Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode sheet supply devices fail to securely maintain stacked electrode sheets, leading to instability and potential falling or offsetting during the pickup process, especially when sheets are warped or wavy.
Innovation Solution
A placement method utilizing a restraint device with a restraining blade and a transfer device with a transfer plate to securely pick up and hold the topmost layer sheet, ensuring stability by switching between restraining and non-restraining states and adjusting the transfer plate's angle to prevent sheets from falling or becoming offset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stacked electrode sheets are not fixed in place, then the pickup process is simple, but the sheet members fall down or become offset when stacked in an unstable state
Solution Approach 1:
The restraint device is activated before the pickup operation to pre-stabilize the stacked sheet members. By pressing the restraining blade against the sheets in advance, the system prevents potential falling or offsetting during subsequent pickup, resolving the contradiction between simple operation and stack stability.
Solution Approach 2:
The restraint device acts as an intermediary between the stacked sheets and the pickup operation. It provides temporary stabilization during the pickup process without interfering with the simplicity of the operation, allowing sheets to be securely held while maintaining ease of pickup.
2Reliability
If the restraining blade continuously presses the sheet members, then the sheets remain stable, but the topmost layer sheet member cannot be picked up
Solution Approach 1:
The restraint device operates periodically rather than continuously. It activates the restraining blade before pickup, releases it during pickup, and reactivates it after pickup. This periodic operation maintains sheet stability while enabling efficient pickup of the topmost layer sheet member.
Solution Approach 2:
The restraint device transitions between different states (restraining and non-restraining) based on the pickup process requirements. This dynamic adjustment allows the system to maintain stability when needed and enable pickup when needed, resolving the contradiction between continuous restraint and pickup efficiency.
3Ease of operation
If the transfer plate is always horizontal, then the pickup process is simple, but warped or wavy sheets cannot be properly handled
Solution Approach 1:
The transfer plate is designed to be dynamically adjustable between horizontal and inclined states. It starts horizontal for simple pickup, inclines to accommodate warped or wavy sheets during the pickup process, and returns to horizontal for transfer. This dynamic adjustment maintains operational simplicity while enhancing handling capability.
Solution Approach 2:
The inclination angle of the transfer plate is changed as needed during the pickup process. By adjusting this parameter, the system can handle both flat and warped sheets effectively while maintaining the simplicity of the overall pickup operation.

AI summary
A placement method using a placement device provided with a first process of pressing a transfer plate a topmost layer sheet member so as to pick up it when a restraint device is rendered a restraining state, a second process of rendering the restraint device a non-restraining state to render the transfer plate an inclined state while pressing down the plurality of sheet members from above in the stacking direction by a base end part side of the transfer plate rendered the inclined state, a third process of inserting the restraining blade into the space formed between the topmost layer sheet member and the sheet member of the layer below it and again render the restraint device the restraining state, and a fourth process of making the transfer plate retract upward while returning it to the horizontal state and transferring the topmost layer sheet member to the holder.
