[0029] The utility model discloses a glass flatness detection device, such as Figure 1 And Figure 2 As shown, including device mesa 10, device mesa 10 includes detection area 110;Detection frame body 20, detection frame body 20 includes support column 210 and slide rail 220, and slide rail 220 is located on support column 210, and detection frame body 20 is located at one side of detection area 110;Detection assembly 30, detection assembly 30 includes horizontal shift piece 310, first detection piece 320 and second detection piece 330, and horizontal shift piece 310 is slidably connected with slide rail 220, and first detection piece 320 is located at the lower part of horizontal shift piece 310, and second detection piece 330 is located at one end of horizontal shift piece 310;Light blocking piece 40, light blocking piece 40 is located at one side of detection area 110.

[0030] In this way, by locating light blocking piece 40 at one side of detection area 110, the influence of external light on detection area 110 can be reduced, first detection piece 320 and second detection piece 330 are located on horizontal shift piece 310, and horizontal shift piece 310 is slidably connected with slide rail 220, and the detectable range of the detection piece is increased by means of slide rail 220.

[0031] In at least one of the possible embodiments, the device mesa 10 further comprises an opening 120, which can be used to clean the glass products that do not meet the requirements. In the process of glass flatness detection, it is inevitable to encounter some products that do not meet the quality requirements. The traditional detection device may need to remove these unqualified products through complex operation or additional tools. However, the opening 120 provided in the embodiment allows the operator to quickly and conveniently clean the glass products that do not meet the requirements through the opening 120, thereby improving the work efficiency. The unqualified products are cleaned in time, which can avoid their accumulation in the detection area 110 and affect the detection of subsequent products. The design of the opening 120 makes the production process more coherent and smooth, thereby improving the overall production efficiency.

[0032] In at least one of the possible embodiments, the light blocking piece 40 is vertically arranged with the detection area 110. The vertical arrangement of the light blocking piece 40 with the detection area 110 can form a direct barrier to effectively block the external light from the side of the detection area 110. This vertical structure ensures that the light cannot be obliquely incident into the detection area 110, thereby reducing the interference of specular reflection and scattered light on the detection imaging, and improving the accuracy and stability of the detection.

[0033] In at least one of the possible embodiments, the detection frame 20 comprises two support columns 210, and the slide rail 220 is arranged at least partially between the two support columns 210. More specifically, the extension direction of the slide rail 220 is arranged parallel to the detection area 110. The design of the two support columns 210 provides a more stable support structure, ensuring the overall stability of the detection frame 20. This double-column 210 structure can withstand greater loads, adapting to detection assemblies 30 of different weights and sizes, ensuring the reliability and accuracy of the detection process.

[0034] In at least one of the possible embodiments, the first detection member 320 is a visual detector. More specifically, the first detection member 320 comprises multiple camera modules. The inclusion of multiple camera modules in the first detection member 320 means that the glass surface can be imaged simultaneously from multiple angles or positions. This multi-angle imaging approach can more comprehensively capture information about the glass surface, improving the accuracy and reliability of the detection. The multiple camera modules also enable a redundant design, so that even if one or several modules fail, the others can still continue to work, ensuring the continuity and stability of the detection process. By adjusting the positions, angles, and focal lengths of different camera modules, the detection needs of glass products of different sizes, shapes, and specifications can be met. This flexibility allows the same detection system to be applied to multiple production scenarios, reducing the cost and complexity of the equipment. Multiple camera modules can work simultaneously and process image data in parallel, greatly improving the efficiency of detection. This parallel processing approach can shorten the detection time and meet the needs of high-speed production lines.

[0035] In at least one of the possible embodiments, the detection assembly 30 further comprises a third detection member 340 arranged at one end of the slide rail 220. The third detection member 340 can be used to detect the levelness of other detection members or / and the traversing member 310. In the process of detecting the flatness of glass, it is crucial to ensure the levelness of other detection members (such as visual detectors) and the traversing member 310 (a component for moving detection members). Deviation in levelness can lead to errors in detection results, affecting product quality control. By introducing the third detection member 340, the levelness of other detection members and the traversing member 310 can be monitored and adjusted in real time, thereby reducing detection errors caused by levelness deviation. This helps to improve the precision and reliability of detection, ensuring the stability of product quality.

[0036] In at least one of the possible embodiments, the width of the light-blocking piece 40 is greater than the width of the detection area 110. The width of the light-blocking piece 40 being greater than the width of the detection area 110 means that it can more comprehensively block external light from the side of the detection area 110. This ensures that light cannot be obliquely incident into the detection area 110 from the edges of the light-blocking piece 40, effectively reducing the interference of specular reflection and scattered light on the detection imaging. Since the light-blocking piece 40 can more comprehensively block external light, the light environment in the detection area 110 becomes more stable. This stability helps to improve the accuracy and reliability of the detection, because fluctuations in external light no longer have a significant impact on the detection results. If the width of the light-blocking piece 40 is the same as or slightly smaller than the width of the detection area 110, it may be necessary to frequently adjust the position or angle of the light-blocking piece 40 in actual application to adapt to different detection needs. The light-blocking piece 40 with a greater width reduces the need for such adjustments, improving work efficiency.

[0037] In at least one of the possible embodiments, the glass flatness detection device provided by the embodiment of the present application further comprises a table height adjusting piece 50, which is arranged at least at three corners of the device table 10. The device table 10 can be ensured to be horizontal by adjusting the table height adjusting piece 50. The main function of the table height adjusting piece 50 is to adjust the height of the device table 10, and through precise adjustment, it can be ensured that the table remains horizontal in any use environment. By adjusting the table height adjusting piece 50, it can be ensured that the device table 10 forms good contact and support with the ground, thereby enhancing the stability of the equipment.

[0038] Compared with the prior art, the glass flatness detection device provided by the embodiment of the present application effectively blocks external light from directly irradiating the detection area 110 by arranging a light-blocking piece 40 on one side of the detection area 110, reduces the phenomenon of specular reflection and local overexposure or shadow blocking, and thereby improves the stability and detection precision of imaging. By optimizing the layout and movement mode of the detection assembly 30, the detection piece can more accurately capture information of the glass edge. At the same time, reducing external light interference and specular reflection also helps to improve the clarity of edge detection, thereby enhancing the reliability of the edge detection algorithm. The sliding connection structure of the transverse moving piece 310 and the slide rail 220 increases the detectable range of the detection piece. This enables the detection assembly 30 to move along the slide rail 220 to detect different areas of the glass surface. This not only improves the flexibility of detection, but also greatly shortens the detection time and improves the detection efficiency.

[0039] The above merely is preferable specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the technical field can easily think of the change or replacement in the utility model disclosed technology range, and all should be covered in the protection scope of the utility model.
