Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The detection of forming tool length and outer diameter is complicated due to the need for a backlight source and image sensor to be on opposite sides for diameter detection and on the same side for length detection, making the process cumbersome.
Innovation Solution
A forming tool detection apparatus using a reflector module to reflect light from a backlight module, allowing an image sensor to capture images of both the length and outer diameter of the forming tool, with an adjustment module for precise positioning and focusing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a backlight source and image sensor are placed on opposite sides of the forming tool for outer diameter detection, then measurement precision of outer diameter is improved, but device complexity and detection process complexity increase
Solution Approach 1:
A reflector module is introduced as an intermediary component between the backlight source and image sensor. The reflector reflects light from the backlight source back through the forming tool to the image sensor, enabling both length and outer diameter detection when all components are positioned on the same side, thus simplifying the detection process while maintaining measurement precision
Solution Approach 2:
The detection apparatus is designed to perform multiple detection functions (length measurement and outer diameter measurement) using a single unified optical path configuration with the reflector module, eliminating the need for separate detection setups and reducing overall system complexity
2Ease of operation
If the light source and image sensor are positioned on the same side for length detection, then ease of operation is improved, but measurement precision of outer diameter deteriorates
Solution Approach 1:
The reflector module serves as a light redirecting intermediary that enables same-side positioning of the backlight source and image sensor while maintaining sufficient light intensity and image quality for accurate outer diameter measurement, thus achieving both operational simplicity and measurement precision
3Measurement precision
If separate detection processes are used for length and outer diameter, then measurement precision of individual parameters is improved, but loss of time increases
Solution Approach 1:
The detection apparatus merges length detection and outer diameter detection into a single simultaneous detection process by using the reflector module to create an optical path that captures both dimensional information in one image capture, eliminating the need for sequential detection and reducing detection time while maintaining precision

AI summary
A forming tool detection device includes a reflector module, an image sensor and a backlight module respectively disposed on both sides of the reflector module with a detection space formed between the backlight module and the reflector module for the insertion of a forming tool for detection. The reflector module focuses the light projected by the backlight module and reflects the focused light toward the backlight module and is provided with a hollow portion for the image sensor to capture an image of the forming tool. The reflector module is used to reflect the light emitted by the backlight module so that the tool image captured by the image sensor can detect the length and outer diameter of the forming tool, thereby simplifying the tool detection process.
