Interposer Depth Offset Measurement for Battery Die Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in battery manufacturing lies in precisely determining the offset position of an interposer within a die to enhance the precision and efficiency of the extrusion process, as existing methods lack accuracy and versatility in aligning the interposer with the die's cavity.
Innovation Solution
A positioning apparatus comprising a fixation portion, a projecting member, and an offset gauge is used to determine the depth offset of the interposer, allowing for precise alignment and adjustment within the die's cavity, which includes a mechanism for electromagnetic fixation and manual or automatic movement of the projecting member to ensure accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used to determine interposer position, then the manufacturing process is simpler, but the measurement precision and alignment accuracy are insufficient
Solution Approach 1:
A positioning apparatus is introduced as an intermediary tool between the die and the interposer. The apparatus includes a projecting member that physically contacts the interposer and an offset gauge that measures the depth offset, serving as a mediator to transfer and quantify the positional relationship between the die and interposer with high precision.
Solution Approach 2:
The patent replaces conventional mechanical alignment methods with a measurement-based approach. Instead of relying on mechanical fixtures or visual alignment, the invention uses an offset gauge to precisely measure the depth offset of the projecting member, converting a mechanical positioning problem into a measurable quantity that can be accurately determined and adjusted.
2Productivity
If manual alignment methods are used, then the apparatus is simpler, but the productivity and efficiency of the battery manufacturing process decrease
Solution Approach 1:
The positioning apparatus is used before the extrusion process to pre-determine and adjust the interposer position. By performing the measurement and alignment operation in advance, the apparatus ensures that the interposer is correctly positioned before production begins, preventing rework and improving overall manufacturing efficiency without adding complex real-time control systems.
3Manufacturing precision
If the projecting member is moved manually, then the apparatus is easier to operate, but the positioning precision and consistency are reduced
Solution Approach 1:
The offset gauge provides immediate feedback on the depth offset of the projecting member. As the projecting member is moved into the cavity, the gauge continuously indicates the measured offset value, allowing the operator to see the exact position and make precise adjustments to achieve the target alignment accuracy.
