Panel Polishing Device With Oblique Spray Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel polishing methods result in incomplete cleaning due to 'polishing blind regions' on both sides of the panel, where the bi-component fluid spray does not effectively reach, leading to incompletely cleaned surfaces.
Innovation Solution
A panel polishing device with a spray head featuring oblique through-holes on both sides, aligned with the movement direction of the polishing belt, ensures a wider application of the bi-component fluid, eliminating blind regions by increasing the contact area between the polishing belt and the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the spray head uses vertical through-holes to spray bi-component fluid onto the polishing belt, then the spray structure is simple and easy to manufacture, but polishing blind regions occur on both sides of the panel resulting in incomplete cleaning
Solution Approach 1:
The spray head employs asymmetric through-hole configurations where side through-holes are oblique relative to the movement direction while central through-holes remain vertical. This asymmetric design allows the bi-component fluid to be sprayed both vertically and at angles, eliminating the polishing blind regions on both sides of the panel while maintaining manufacturing simplicity.
2Device complexity
If the spray head sprays bi-component fluid only onto the central region of the polishing belt, then the spray head structure is simple, but the polishing belt cannot fully contact the panel edges resulting in blind regions
Solution Approach 1:
The spray head is segmented into multiple through-hole groups: central vertical through-holes for the main spray region and oblique side through-holes for edge coverage. This segmentation allows each group to target specific areas of the polishing belt, ensuring complete coverage from center to edges without increasing overall device complexity.
Solution Approach 2:
The spray coverage is extended from a single vertical dimension to multiple dimensions by introducing oblique side through-holes. This dimensional expansion allows the bi-component fluid to reach the edges of the polishing belt that were previously inaccessible, increasing the effective polishing area.
3Manufacturing precision
If the polishing belt contacts the panel over a larger area to eliminate blind regions, then cleaning completeness improves, but abrasion on the polishing belt increases reducing its service life
Solution Approach 1:
The oblique side through-holes are strategically positioned to spray bi-component fluid precisely at the edges of the polishing belt where blind regions occur. This localized application ensures complete cleaning at the edges without requiring the entire polishing belt to undergo excessive abrasion, thereby extending its service life while maintaining cleaning completeness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures thorough cleaning of panels without blind regions, reducing abrasion on the polishing belt and extending its service life, while also allowing for auto-controlled and efficient operation.
Implementation Method 1
spraying bi-component fluid (i.e., water and gas) to a polishing belt through a spray head such that the bi-component fluid can wet the polishing belt
Implementation Method 2
pressing the wetted polishing belt against a panel to be polished. By polishing, foreign matters on the surfaces of the panel can be removed

AI summary
Disclosed is a panel polishing device, comprising a polishing belt movable along a predefined direction and a spray head arranged above the belt. The spray head has a main body and a plurality of through-holes penetrating the main body in its thickness direction. Through-holes have outlets facing the belt and are arranged along a length direction of the spray head. The length direction of the spray head conforms to a movement direction of the belt. At least the through-holes on both sides of the main body are oblique outwardly with respect to the remaining through-holes. Also, the disclosure provides a panel cleaning equipment including the panel polishing device. In the device according to the disclosure, pressure of bi-component fluid is more widely applied onto belt and a larger belt is contacted with the panel, such that the panel is thoroughly cleaned without polishing blind regions on both sides thereof.
