[0002] In modern manufacturing, as a key component of a dicing machine, the detection of the wear state of a cutter wheel is crucial for ensuring product quality and production safety. Traditional cutter wheel detection methods usually rely on manual inspection or simple mechanical measurement. These methods have many limitations, such as slow detection speed, low accuracy, being easily affected by the subjective judgment of operators, and it is difficult to achieve automation and real-time monitoring.

[0003] With the development of industrial automation and intelligence, higher requirements are put forward for cutter wheel detection technology. In related technologies, although there are some automated detection systems, these systems are applied to the detection of high-speed rotating cutter wheels, and often have low detection accuracy, which is difficult to meet the high requirements of modern manufacturing for cutter wheel detection.

[0031] The present utility model provides a cutter wheel detection system 100.

[0032] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the cutter wheel detection system 100 includes an optical amplifier 1, a detection unit 2, and a host computer 3. The optical amplifier 1 is configured to receive an excitation optical signal blocked by the cutter wheel. The detection unit 2 includes a 16-bit analog-to-digital converter 21, a data processing module 22, and a controller 23. The 16-bit analog-to-digital converter 21 is configured to collect the optical intensity signal output by the optical amplifier 1 in real time. The data processing module 22 is configured to present the contour of the cutter wheel according to the collected optical intensity signal. The controller 23 is configured to judge the working condition of the cutter wheel according to the contour of the cutter wheel. The host computer 3 is configured to receive the working condition of the cutter wheel obtained by the controller 23.

[0033] In the technical solution of the present utility model, the main task of the optical amplifier 1 is to receive the optical signals from the excitation light source. These signals will be attenuated or changed after being blocked by the cutting wheel. The optical amplifier 1 increases the intensity of these optical signals to ensure that the signals are strong enough for the subsequent analog-to-digital converter to accurately collect. The 16-bit analog-to-digital converter 21 is responsible for converting the analog optical intensity signal output by the optical amplifier 1 into a digital signal. The 16 bits refer to the resolution of the analog-to-digital converter, which means that it can precisely divide the signal into 65536 (i.e., 2 to the power of 16) different levels. This high resolution helps to accurately capture the minute changes in the optical intensity and can greatly improve the detection accuracy of the cutting wheel detection system 100. The data processing module 22 analyzes the digital signal obtained from the analog-to-digital converter to generate the contour of the cutting wheel. This process involves techniques such as signal filtering, noise reduction, and feature extraction to clearly depict the actual shape or state of the cutting wheel. The controller 23 receives and interprets the cutting wheel contour information generated by the data processing module 22 and uses this information to judge the working state (operating condition) of the cutting wheel. Based on the contour data, the controller 23 can perform system adjustment, anomaly detection, or other decision-making operations. The host computer 3 is used to receive the cutting wheel operating condition data output by the controller 23. These data are usually used for display, recording, and further analysis. The user can view the state of the cutting wheel through the interface of the host computer 3 to conduct fault troubleshooting or maintenance decision-making. The operating condition data of the cutting wheel include but are not limited to whether the cutting wheel is damaged, how many places the cutting wheel is damaged, the wear degree of the cutting wheel, the number of cutting wheel teeth, and the cutting wheel rotation speed, etc.

[0034] Please refer to Figure 2, for facilitating further analysis of the profile and working conditions of the cutting wheel, in an embodiment of the present invention, the detection unit 2 includes a data input module 24 and a data acquisition module 25. The data input module 24 is configured to receive the optical intensity signal of the optical amplifier 1; the data acquisition module 25 is configured to receive the acquired optical intensity signal, and output the received optical intensity signal to the data processing module 22 after processing; wherein, the data acquisition module 25 includes the 16-bit analog-to-digital converter 21. The task of the data input module 24 is to receive the amplified optical intensity signal from the optical amplifier 1. It is the first step of data acquisition, responsible for obtaining the optical signals output by the optical amplifier 1 and preparing these signals for subsequent processing. This module involves signal conditioning or preprocessing to ensure that the signals meet the requirements when transmitted to the data acquisition module 25, such as adjusting the signal intensity, filtering out noise, etc.; the data acquisition module 25 receives the optical intensity signal from the data input module 24. It is the core part of the detection unit 2, responsible for converting the original signal into data that can be further processed. The data acquisition module 25 not only receives the signal, but also includes preliminary processing of the signal. For example, it may involve amplifying, filtering or correcting the signal to ensure signal quality and accuracy. The processed optical intensity signal will be transmitted to the data processing module 22 for further analysis and generating the profile of the cutting wheel; during this process, the analog-to-digital converter receives the analog optical intensity signal from the data input module 24, converts it into the corresponding digital signal, and outputs it to the data processing module 22 for further analysis and generating the profile of the cutting wheel.

[0035] To ensure that the acquired data is accurate and comprehensive enough to meet specific detection and analysis requirements, in an embodiment of the present invention, the sampling frequency range of the data acquisition module 25 is from 100k to 4MHz, and the number of channels is from 4 to 8. The sampling frequency is the number of times the signal is sampled per second. A low sampling frequency is suitable for capturing slower-changing signals, and a high sampling frequency is suitable for capturing faster-changing signals. Selecting the appropriate sampling frequency depends on the frequency characteristics of the measured signal and system requirements. According to the change rate of the signal and analysis requirements, an appropriate sampling frequency can be selected; the number of channels is the number of independent signal channels that the data acquisition module 25 can simultaneously acquire. Each channel can receive an independent signal source. Multi-channel acquisition allows data to be acquired simultaneously from multiple light sources or photodetectors. The data of each channel can be processed independently or together, depending on the design requirements of the system. The optical intensity signal of each channel can be analyzed, the optical profile of each channel can be calculated, and comprehensive analysis can be performed. The configuration of 4 to 8 channels provides flexibility, allowing the system to expand or reduce the number of channels according to specific requirements.
