Sliding Housing Access for Large-Workpiece Dicing Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dicing devices, the increased size of workpieces leads to longer strokes of the worktable feeding mechanism, resulting in reduced accessibility and efficiency during maintenance tasks due to increased distance from the maintenance area to the blade.
Innovation Solution
A slider is integrated into the dicing device's housing, allowing for sliding movement between a protruding position during processing and a retracted position during maintenance, effectively shortening the access distance to the blade and improving maintenance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stroke of the worktable feeding mechanism is increased to accommodate larger workpieces, then the processing capability is improved, but the accessibility to the blade during maintenance work deteriorates
Solution Approach 1:
The end face of the housing is designed to be movable rather than fixed. It can slide between a first position during dicing processing (where it does not interfere with the worktable stroke) and a second position during maintenance work (where it provides access to the blade). This dynamic repositioning resolves the contradiction by allowing the system to adapt its structure based on operational mode.
Solution Approach 2:
The housing end face is separated from the main housing structure, allowing it to move independently. This segmentation enables the end face to be repositioned relative to the blade and worktable, providing accessibility during maintenance while maintaining processing capability during operation.
2Reliability
If the distance from the maintenance area to the blade is increased for safety, then the safety is improved, but the efficiency of blade replacement work deteriorates
Solution Approach 1:
The end face distance from the blade is dynamically adjusted based on operational needs. During maintenance, the end face moves to a position closer to the blade, reducing the distance and improving replacement efficiency. During processing, it maintains a safer distance, thus balancing safety and efficiency.
3Adaptability or versatility
If the stroke of the worktable feeding mechanism is lengthened, then the workpiece size accommodation is improved, but the maintenance work efficiency deteriorates
Solution Approach 1:
The movable end face allows the maintenance area to be repositioned closer to the blade when needed, reducing maintenance time. This dynamic adjustment compensates for the time loss caused by the longer stroke required for larger workpieces.

AI summary
Provided is a dicing device capable of favorably performing a maintenance work, even when a workpiece is large. A dicing device includes a housing that accommodates inside thereof, a worktable configured to hold and move a workpiece, and a spindle configured to be rotatable while holding a blade, wherein the housing has: an end face provided in a moving direction of the worktable, the end face being on a side where a maintenance work of the dicing device is performed; and a slider constituting a part of the end face, and the slider is configured to be freely slidable in a direction to shorten a distance from the end face to the spindle.
