Substrate Case Cleaning Apparatus Movement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional substrate case cleaning apparatuses face complexity and difficulty in moving and positioning substrate cases due to the need for arm robots to extend and grip the cases, making the operation cumbersome and requiring intricate programming.
Innovation Solution
A substrate case cleaning apparatus with a booth and a support table that uses a movement mechanism with a stand, rail, and advance/retraction drive to move the substrate case between a setting table and a support table, eliminating the need for arm robots to grip the case, and incorporating engagement recesses and projections for precise positioning and suction disks for secure handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an arm robot is used to grip and move the substrate case from the setting table to the support table, then the substrate case can be transported, but the operation becomes complicated and programming becomes troublesome
Solution Approach 1:
The substrate case is divided into separable components (base and shell) that can be handled independently. The base is conveyed by the base conveyance mechanism while the shell is conveyed by the shell conveyance mechanism, eliminating the need for a complex arm robot to grip and maneuver the entire assembled case.
Solution Approach 2:
Conveyance mechanisms with engagement protrusions and recesses serve as intermediaries to transfer the substrate case components between the setting table and support table. These specialized conveyance structures replace the general-purpose arm robot, providing automated handling without complex gripping operations.
2Manufacturing precision
If an arm robot grips the substrate case as a whole to move it, then the case can be transported, but positioning on the support table becomes troublesome
Solution Approach 1:
By separating the base and shell conveyance operations, each component can be precisely positioned using dedicated conveyance mechanisms with matching engagement features, achieving accurate positioning without the complexity of manipulating the entire assembled case.
Solution Approach 2:
The base conveyance mechanism and shell conveyance mechanism have localized engagement structures (protrusions and recesses) designed specifically for their respective components, enabling precise positioning tailored to each part's geometry rather than using a general-purpose gripping approach.
3Adaptability or versatility
If the arm robot extends from the booth opening to the setting table, then the substrate case can be accessed, but the structure becomes more complex
Solution Approach 1:
The conveyance system is segmented into a base conveyance mechanism and a shell conveyance mechanism, each with dedicated engagement structures. This eliminates the need for a versatile arm robot that can grip various configurations, replacing it with specialized mechanisms that are simpler in structure.
Solution Approach 2:
Dedicated conveyance mechanisms with engagement protrusions and recesses act as intermediaries between the booth interior and the setting table, providing automated access and transfer functionality without requiring an extending arm robot structure.
