Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass manufacturing and quality inspection technology, and in particular to a high-strength glass manufacturing quality inspection device. Background Technology
[0002] High-strength glass plays a vital role in modern industry due to its excellent mechanical properties and wide range of applications, especially in construction, automotive manufacturing, and electronic equipment. However, the manufacturing quality of high-strength glass directly affects its performance and safety, making rigorous quality inspection during production crucial. Currently, quality inspection of high-strength glass primarily relies on manual inspection or traditional testing equipment. While these methods meet basic requirements to some extent, they also have significant shortcomings. For example, manual inspection is inefficient and easily influenced by subjective factors, leading to inaccurate results; traditional testing equipment is typically single-function and cannot comprehensively assess various performance indicators of glass, such as strength, flatness, and surface defects. Furthermore, existing testing devices still have considerable room for improvement in automation and accuracy, especially when facing large-volume, high-precision testing needs, often struggling to balance efficiency and accuracy. Therefore, developing a high-strength glass manufacturing quality inspection device that is efficient, accurate, and multifunctionally integrated has become an urgent technical challenge.

[0013] The attached diagram is labeled as follows: 1. Stress detection module; 2. Thickness measurement module; 3. Surface defect detection module; 4. Edge strength detection module; 5. Data processing unit; 6. Storage database; 7. Alarm module; 8. Shutdown protection unit; 9. Pressure simulation unit. Detailed Implementation
[0014] This utility model provides a high-strength glass manufacturing quality inspection device, the specific implementation of which is described in conjunction with the appendix. Figure 1 Please provide a detailed explanation. For example... Figure 1 As shown, the device includes a stress detection module 1, a thickness measurement module 2, a surface defect detection module 3, an edge strength detection module 4, a data processing unit 5, a storage database 6, an alarm module 7, a shutdown protection unit 8, and a pressure simulation unit 9. These modules and units are connected and cooperate through signal transmission paths to complete comprehensive quality inspection of high-strength glass.
[0015] In actual operation, the stress detection module 1 first detects the internal stress of the high-strength glass. The stress detection module 1 typically uses laser scattering or polarized light technology to measure the residual stress distribution inside the glass. After detection, the stress detection module 1 sends the generated stress signal to the data processing unit 5. The data processing unit 5 performs preliminary processing on the received stress signal, such as filtering, amplification, and digitization, and transmits the processed signal to the storage database 6. The storage database 6 stores standard stress range values for comparison and analysis with the current detection results. If the detected stress value exceeds a preset safety threshold, the storage database 6 transmits the abnormal result to the alarm module 7, and the data processing unit 5 also transmits the processed stress signal to the shutdown protection unit 8. The shutdown protection unit 8 has a stress safety threshold. When the received signal indicates that the glass stress exceeds the safe range, the shutdown protection unit 8 immediately issues a command to stop the production line to avoid equipment damage or product scrap in subsequent processes.
[0016] Next, the thickness measurement module 2 detects the thickness uniformity of the high-strength glass. The thickness measurement module 2 includes an upper thickness measurement unit and a lower thickness measurement unit, located on the upper and lower sides of the glass respectively. It acquires the glass thickness data using non-contact laser ranging technology. The upper and lower thickness measurement units generate upper and lower thickness signals respectively, and send these signals to the data processing unit 5. The data processing unit 5 integrates and calculates the received thickness signals to determine the overall thickness distribution of the glass, and transmits the processed signals to the storage database 6. The standard thickness range values pre-stored in the storage database 6 are used for comparative analysis with the current detection results. If the detection results show that the glass thickness is uneven or exceeds the allowable range, the storage database 6 will transmit the abnormal result to the alarm module 7, simultaneously triggering the shutdown protection unit 8.
[0017] Subsequently, the surface defect detection module 3 performs a comprehensive inspection of the surface quality of the high-strength glass. The surface defect detection module 3 includes a scratch detection unit, a crack detection unit, and a bubble detection unit. The scratch detection unit captures scratch images of the glass surface using a high-resolution camera and uses image processing algorithms to identify the location and depth of the scratches; the crack detection unit uses ultrasonic detection technology to detect the presence of micro-cracks on the glass surface; and the bubble detection unit uses optical scanning technology to detect the presence of bubble defects inside the glass. These three units generate scratch signals, crack signals, and bubble signals respectively, and send these signals to the data processing unit 5. The data processing unit 5 classifies and processes the received signals, such as performing morphological analysis on scratch signals, spectral analysis on crack signals, and volume calculation on bubble signals, and transmits the processed signals to the storage database 6. The standard defect range values pre-stored in the storage database 6 are used for comparative analysis with the current detection results. If the detection results show that there are serious defects on the glass surface, the storage database 6 will transmit the abnormal result to the alarm module 7 and simultaneously trigger the shutdown protection unit 8.
[0018] Finally, the edge strength detection module 4 detects the edge strength of the high-strength glass. The edge strength detection module 4 receives a simulated load signal from the pressure simulation unit 9, applies a certain mechanical pressure to the glass edge, and records the glass deformation and fracture strength. The pressure simulation unit 9 can generate simulated load signals of different intensities according to different glass specifications and application scenarios to ensure the accuracy and applicability of the test results. The edge strength detection module 4 sends the generated strength detection signal to the data processing unit 5. The data processing unit 5 processes the received strength signal, such as calculating the edge compressive strength and fracture toughness, and transmits the processed signal to the storage database 6. The standard strength range values pre-stored in the storage database 6 are used for comparative analysis with the current test results. If the test results show insufficient glass edge strength, the storage database 6 will transmit the abnormal result to the alarm module 7 and simultaneously trigger the shutdown protection unit 8.
[0019] Throughout the entire inspection process, the data processing unit 5 processes signals from the stress detection module 1, thickness measurement module 2, surface defect detection module 3, and edge strength detection module 4 in a fixed order. This sequential processing method ensures the efficiency and accuracy of the inspection process. Simultaneously, the data processing unit 5 is also responsible for transmitting the processed signals to the alarm module 7 and the shutdown protection unit 8 to enable timely response to quality issues.
[0020] The alarm module 7 includes an audible and visual alarm unit and a display screen unit. When the comparison data transmitted from the storage database 6 indicates a quality problem with the glass, the alarm module 7 will issue an alarm through the audible and visual alarm unit, such as flashing warning lights and a buzzer sound, to alert the operator. Simultaneously, the display screen unit uses an LCD screen to display the test data and quality assessment results in real time, allowing operators to quickly understand the specific situation. For example, the display screen unit can display information such as the glass's stress value, thickness distribution map, surface defect location, and edge strength test results.
[0021] The shutdown protection unit 8 monitors the quality parameters of the glass and immediately issues a shutdown command when an abnormality is detected. The shutdown protection unit 8 is equipped with multiple safety thresholds, including a stress safety threshold, a thickness safety threshold, a defect safety threshold, and a strength safety threshold. When a received signal indicates that a certain parameter of the glass exceeds the corresponding safety threshold, the shutdown protection unit 8 immediately sends a shutdown command to the production line control system to prevent defective products from entering subsequent processes. This automated protection mechanism not only effectively avoids equipment damage or product scrap due to quality problems but also significantly improves production efficiency and product quality stability.
[0022] In summary, the high-strength glass manufacturing quality inspection device provided by this utility model comprehensively inspects the internal stress, thickness uniformity, surface quality, and edge strength of high-strength glass through a stress detection module 1, a thickness measurement module 2, a surface defect detection module 3, and an edge strength detection module 4. Through signal processing by the data processing unit 5 and comparative analysis by the storage database 6, combined with the audible and visual prompts of the alarm module 7 and the automatic shutdown function of the shutdown protection unit 8, real-time monitoring and efficient management of high-strength glass quality are achieved. This inspection device not only ensures that quality problems in the production process are detected and handled in a timely manner, but also significantly improves production efficiency and product quality stability, providing reliable technical support for the manufacturing of high-strength glass.
