Peeling Apparatus Discarding Unit Inclined Plate Air Jet Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional peeling apparatuses struggle to properly stack protective members in a trash box due to changes in resin hardness or thickness, leading to improper stacking and increased worker burden when extracting filled trash boxes.
Innovation Solution
A peeling apparatus with a discarding unit featuring inclined plates and air jets that guide the protective member to form a protruding shape, allowing it to pass through the trash box opening and stack horizontally, even with varying resin properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hardness or thickness of the resin is increased to accommodate greater undulation or warp, then the protective member can better hold the wafer flatly, but the force necessary to bend the protective member changes and the degree of bending differs among protective members, causing improper stacking in the trash box
Solution Approach 1:
The patent introduces an air blowing unit that changes the physical state of the protective member by applying airflow. This allows the protective member to be bent to a consistent degree regardless of its hardness or thickness variations, enabling proper stacking in the trash box while maintaining the ability to accommodate different wafer undulations and warps through resin parameter changes
2Adaptability or versatility
If different liquid resins are used to change hardness or thickness based on undulation or warp magnitude, then the protective member can be customized for different wafer conditions, but the bending force and degree vary among protective members, leading to improper stacking
Solution Approach 1:
The air blowing unit acts as an intermediary between the protective member and the stacking process. By introducing controlled airflow, it standardizes the bending degree of protective members with varying resin properties, ensuring uniform stacking in the trash box while preserving the ability to select different resins for different wafer conditions
3Device complexity
If only two inclined pipes are used to bend and drop the protective member, then the structure is simple, but protective members with varying hardness or thickness cannot be consistently bent and stacked properly in the trash box
Solution Approach 1:
The patent merges the air blowing unit with the existing inclined pipe structure. The air blowing unit is positioned to blow air toward the interior of the trash box, working in conjunction with the inclined pipes to consistently bend and guide protective members into proper stacking positions, thereby improving stacking reliability without significantly increasing structural complexity
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
Ensures proper stacking of protective members within the trash box, reducing the frequency of worker intervention and maintaining efficient disposal despite changes in resin hardness or thickness.
Implementation Method 1
a holding unit configured to hold another surface of the wafer under suction on a holding surface
Implementation Method 2
the first inclined plate and the second inclined plate each have a first air jetting port configured to jet air
Implementation Method 3
two pipes that are arranged individually on a lower end side of the first inclined plate and a lower end side of the second inclined plate and that each have a second air jetting port configured to jet air, and the air jetted from the second air jetting port generates airflow moving upward from below
Implementation Method 4
an inclined dropping unit configured to drop the protective member gripped by the gripping unit obliquely downward to the opening of the trash box

AI summary
A peeling apparatus includes a discarding unit configured to discard a protective member by stacking the protective member in a trash box. The discarding unit includes an inclined dropping unit configured to drop the protective member obliquely downward to an opening of the trash box, and a first inclined plate and a second inclined plate that arranged so as to face each other in a direction orthogonal to a traveling direction of the protective member when the protective member dropping obliquely downward above the opening is viewed from above. The first inclined plate and the second inclined plate are arranged such that a gap through which the protective member can pass is formed between a lower side of the first inclined plate and a lower side of the second inclined plate, and the first inclined plate and the second inclined plate are inclined.
