Transparent Holding Table Cleaning for Clear Cutting Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue with existing cutting apparatuses is that cutting water supplied during the cutting process can adhere to the holding table, causing water drops to appear in the image of the workpiece through a transparent section, which worsens the detected state and makes it difficult to accurately detect cut grooves and patterns.
Innovation Solution
A cutting apparatus equipped with a holding table having a transparent section, a cutting unit with a cutting blade, a cutting water nozzle, an imaging camera, and a removing unit that includes a contact member or a jetting section to remove liquid from the transparent section, ensuring clear imaging by eliminating water droplets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a transparent section is used in the holding table to enable imaging of the workpiece from below, then the ability to image and detect the workpiece is improved, but cutting water adhering to the holding table causes water drops to appear in the image, worsening the detection state
Solution Approach 1:
The removing unit is activated before the imaging step to remove cutting water from the transparent section in advance. This preliminary removal action ensures that when imaging occurs, the transparent section is free of water drops, thus preventing image degradation while maintaining the ability to image through the transparent section
Solution Approach 2:
The removing unit acts as an intermediary between the cutting process and the imaging process. It removes the harmful cutting water from the transparent section, mediating between the water-spraying cutting operation and the clear imaging operation, allowing both to coexist without interference
2Productivity
If cutting water is supplied during cutting to improve cutting performance, then cutting effectiveness is improved, but cutting water adheres to the holding table, worsening the imaging quality
Solution Approach 1:
The removing unit removes cutting water from the transparent section before imaging occurs. This preliminary removal ensures that even though cutting water is supplied during cutting for improved efficiency, the imaging quality is not degraded because the water is removed in advance of the imaging step
Solution Approach 2:
The removing unit operates periodically at specific stages (before imaging, and potentially after cutting) to remove cutting water. This periodic removal action allows continuous cutting with water supply while maintaining image quality at critical imaging moments
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 effectively prevents water droplets from interfering with the image, thereby improving the accuracy of workpiece detection and maintaining a clear, undistorted view of the workpiece, enhancing the overall detection state.
Implementation Method 1
a contact member that is positioned at a contact position for making contact with the transparent section and a retracted position, and a moving mechanism that relatively moves on the transparent section the contact member making contact with the transparent section
Implementation Method 2
a jetting section that jets air toward the transparent section, and a moving mechanism that moves the jetting section on the transparent section
