Printing Head Chip Layout for Mounting Deviation Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light-emitting element arrays in light-sensitive printing technologies often suffer from mounting deviations, which disrupt the uniform distribution of printing points due to misalignment between light-emitting modules, leading to suboptimal printing quality.
Innovation Solution
A method and printing head design that includes light-emitting chips with spare elements, where the transverse spacing between adjacent chips is measured, and spare elements are toggled between light emission enabled and disabled states to adjust for deviations, ensuring uniform exposure and improved printing definition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If light-emitting modules are arranged in an array, then printing efficiency is improved, but mounting deviations cause non-uniform distribution of printing points
Solution Approach 1:
The patent changes the operational parameters of light-emitting elements by adjusting their light emission states (enabled/disabled) to compensate for mounting deviations. By dynamically controlling which elements are active, the system maintains uniform printing point distribution despite physical position variations in the light-emitting modules.
2Adaptability or versatility
If spare light-emitting elements are added to light-emitting chips, then adaptability to mounting deviations is improved, but device complexity increases
Solution Approach 1:
The spare light-emitting elements serve multiple functions: they can replace deviated primary elements, fill gaps in the printing pattern, and maintain uniform distribution. This multi-functional design allows a single structural addition to address various mounting deviation scenarios without requiring completely different chip designs.

AI summary
A printing head and a method for applying a correction for mounting deviation of light-emitting chips are provided. The printing head includes a plurality of light-emitting chips. Each light-emitting chip includes a plurality of primary light-emitting elements that are continuously arranged. At least one of two adjacent light-emitting chips further includes at least one spare light-emitting element continuously and linearly arranged after the primary light-emitting elements. If the two adjacent light-emitting chips are both at a target mounting position, first N light-emitting units of one of the two light-emitting chips respectively face to first N light-emitting units of the other one of the two light-emitting chips, where N≥1. Each two of the light-emitting units facing to each other form a group. One of the two light-emitting units in each of the groups is set to a light emission disabled state.
