Discharge Unit Head Mount Torsion Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid discharge apparatuses face challenges in adjusting gap variations between heads and liquid application targets due to torsional deformation of the mounting surface, which limits processing accuracy and consistency in liquid application.
Innovation Solution
The discharge unit incorporates a head mount with multiple rotation mechanisms and eccentric cams, allowing for independent rotation of the head mount's ends to reduce torsion and adjust gaps effectively, enabling precise alignment and operation from either end of the head mount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If only the inclination angle of the mounting surface is adjustable, then the structure is simple, but it is difficult to adjust gap variation between the head and liquid application target due to torsional deformation
Solution Approach 1:
The head mount is divided into multiple independent sections along its longitudinal direction, each with its own rotation mechanism. This segmentation allows independent adjustment of each section's inclination angle, enabling compensation for torsional deformation while maintaining operational simplicity.
Solution Approach 2:
The mounting structure transitions from a fixed inclination angle to a dynamically adjustable configuration. Each section of the head mount can be independently rotated to change its inclination angle, allowing the system to adapt to torsional deformation and achieve precise gap adjustment.
2Manufacturing precision
If multiple rotation mechanisms are added to independently rotate ends of the head mount, then torsion is reduced and gap adjustment is improved, but the device complexity increases
Solution Approach 1:
The head mount is divided into multiple independent sections along its longitudinal direction, each with its own rotation mechanism. This segmentation allows independent adjustment of each section's inclination angle, enabling compensation for torsional deformation while maintaining operational simplicity.
Solution Approach 2:
Different sections of the head mount are equipped with independent rotation mechanisms that can be adjusted locally. This allows each section to have its own optimal inclination angle, compensating for local torsional deformation without affecting other sections.
3Ease of operation
If the operation part is extended to pass through both side plates, then operation from either end is enabled, but the structure becomes more complex
Solution Approach 1:
The operation part is designed as a universal component that can be accessed and operated from either end of the head mount. This multi-functional design allows a single operation part to control rotation mechanisms at different locations, improving ease of operation without requiring multiple separate controls.
