Modular Coating Die Head for Variable-Width Electrode Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing coating die heads require replacement when producing electrode plates with different widths, leading to increased manufacturing costs due to the need for a die head that matches the specific width of each plate.
Innovation Solution
A modular coating die head design that allows the length of the material chamber to be adjusted by replacing or recombining lip modules, enabling the die head to accommodate electrode plates of varying widths without replacing the entire die head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the entire coating die head is replaced to produce electrode plates with different widths, then the coating precision is maintained, but the manufacturing cost increases
Solution Approach 1:
The coating die head is divided into a die head body and multiple detachable lip modules that can be independently replaced. The lip modules are segmented into first lip modules and second lip modules that can be selectively assembled based on the required electrode plate width, allowing precision maintenance without replacing the entire die head assembly.
Solution Approach 2:
The die head body is designed as a universal base structure that can accommodate different combinations of lip modules. This multi-functional design allows a single die head body to serve multiple width requirements by simply changing the lip module configuration, reducing the need for multiple specialized die heads.
2Adaptability or versatility
If the entire coating die head is replaced for different electrode plate widths, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The die head structure is segmented into modular components (die head body, first lip modules, second lip modules) that can be independently managed and assembled. This segmentation simplifies the overall system complexity by breaking down the monolithic die head into manageable modules with standardized interfaces.
Solution Approach 2:
The die head configuration is made dynamic through the ability to selectively assemble and disassemble different lip module combinations on the same die head body. This dynamic reconfigurability allows adaptability to different widths without permanently altering the base structure, maintaining simplicity while enabling versatility.

AI summary
A coating die head and a coating apparatus including one are provided. The coating die head includes a first die head and a second die head. The first die head includes a first die head body and multiple first lip modules, and the first lip modules are spliced sequentially along a first direction. Each of the first lip modules is detachably connected to the first die head body, each of the first lip modules is provided with a first groove, the first grooves of the plurality of first lip modules are spliced to form a main chamber for storing a slurry, and the first direction is a length direction of the main chamber. In the coating die head, the first lip modules may be replaced or recombined to change the length of the main chamber so that the coating die head is suitable for producing electrode plates with different widths.
