Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notching molds are limited in size flexibility, require mold exchange for different electrode sizes, and struggle with processing deviations when handling electrodes of varying dimensions.
Innovation Solution
A notching mold design featuring a main mold with detachable and adjustable auxiliary molds and strippers, allowing simultaneous processing of non-coated portions at both ends of the electrode base material, with adjustable strippers to stabilize the coated portion during processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed notching mold is used for electrode base materials, then the mold structure is simple, but the mold requires exchange for different electrode sizes and is limited in size flexibility
Solution Approach 1:
The mold is divided into a main mold and multiple detachable auxiliary molds. The auxiliary molds can be selectively attached or detached from the main mold body, allowing the mold structure to be segmented and reconfigured for different electrode sizes without requiring complete mold exchange.
Solution Approach 2:
The auxiliary molds are designed to be movable and adjustable relative to the main mold. This dynamic configuration allows the mold to adapt its structure for processing electrodes of various sizes by positioning the auxiliary molds at appropriate locations, thereby improving size flexibility while maintaining a relatively simple base structure.
2Productivity
If multiple embossed parts and engraved parts are formed to process multiple electrode tabs in one stroke, then processing efficiency improves, but individual adjustment becomes difficult and processing deviation increases
Solution Approach 1:
The mold structure segments the processing functions into the main mold and multiple auxiliary molds. Each auxiliary mold can be independently adjusted and positioned, allowing individual calibration of embossed and engraved parts. This segmentation enables both multi-point processing in one stroke and individual adjustment capability, resolving the contradiction between productivity and precision.
Solution Approach 2:
Each auxiliary mold is designed with locally adjustable features, allowing the embossed and engraved parts on each auxiliary mold to be individually positioned and calibrated. This local quality adjustment capability ensures that each processing point can be precisely tuned while maintaining high productivity through simultaneous multi-point processing.
3Adaptability or versatility
If auxiliary molds are made detachable and adjustable, then adaptability to various electrode sizes improves, but the device complexity increases
Solution Approach 1:
The main mold is designed as a universal base structure that can accommodate multiple types of auxiliary molds for different electrode configurations. The auxiliary molds themselves are multi-functional, capable of performing both embossing and engraving operations. This universality reduces the need for completely different mold sets for various electrode sizes, thereby improving adaptability while controlling overall device complexity.

AI summary
A notching mold for molding a non-coated portion of an electrode base material, wherein the non-coated portion, is formed on each of two ends of a coated portion, includes: a main mold having an upper mold and a lower mold, parallel to each other, and are slidable close to or away from each other. A first auxiliary mold having auxiliary upper and lower molds coupled to the upper and lower molds, respectively, is configured so that the non-coated portion on one end of the electrode base material is disposed at a processible position. A second auxiliary mold having auxiliary upper and lower molds coupled to the upper and lower molds, respectively, is configured so that, when the electrode base material is input into the main mold, the non-coated portion on the other end of the electrode base material is disposed at a processible position.
