[0042] Embodiment 1

[0043] In view of the defects existing in the above-mentioned prior art, based on the rich practical experience and professional knowledge in the design and manufacture of such products for many years by the applicant, and in cooperation with the application of theory, research and innovation have been actively carried out in the hope of creating a technology that can solve the defects in the prior art. Through continuous research, design, and repeated sample making and improvement, a truly practical and valuable utility model has finally been created.

[0044] Please refer to Figure 1 , the embodiment of the present utility model provides a combined detection system, which is jointly composed of an image acquisition device 1, a line light source device 2, and a backlight device 3. Its detailed composition and functions are as follows:

[0045] The image acquisition device 1 is accurately placed above the glass workpiece to be detected, and its main responsibility is to capture detailed image information of the glass workpiece. The application of this device ensures that the image data during the detection process can be accurately and completely obtained, providing a solid foundation for subsequent analysis.

[0046] The line light source device 2 is located above the glass workpiece and is set at a unique inclination angle, emitting bright and uniform light from top to bottom and directly irradiating on the glass workpiece. The design of this device aims to form a synergistic effect with the image acquisition device 1. Through the irradiation of light, surface defects (such as scratches, stains, etc.) on the glass workpiece are highlighted in the image, facilitating subsequent defect detection and analysis.

[0047] The backlight device 3 is cleverly located below the glass workpiece, emitting light from bottom to top and also irradiating on the glass workpiece. The main function of this device is to assist the image acquisition device 1 in more accurately capturing the contour dimensions of the glass workpiece. Through the irradiation of the backlight, the edge contour of the glass workpiece becomes clearer in the image, greatly improving the accuracy of contour dimension detection.

[0048] It should be emphasized that in this embodiment, by ingeniously combining the linear light source device 2 with the backlight device 3, not only the efficient detection of surface defects of glass workpieces is achieved, but also the accuracy of contour dimension measurement is ensured. This integrated design not only greatly improves the detection efficiency and reduces the detection cost, but also provides a strong guarantee for the stability of product quality. The application of this combined detection system will undoubtedly play an important role in the field of glass manufacturing and detection.

[0049] In this embodiment, the image acquisition device 1 is composed of a precision camera and a lens. This design ensures that the image acquisition device 1 can efficiently and accurately capture the image information of the glass workpiece to be detected. Specifically, the lens is carefully set on the camera. As an important part of the camera, it not only determines the clarity and detail performance of the image, but also directly affects the performance of the entire detection system. The perfect combination of the lens and the camera enables the image acquisition device 1 to capture high-definition images of the glass workpiece, providing reliable data support for subsequent defect detection and contour dimension measurement.

[0050] In this embodiment, the combined detection system also includes a carefully designed mounting bracket. This mounting bracket is not only the support foundation of the entire system, but also undertakes the important tasks of fixing and adjusting each component.

[0051] First of all, the image acquisition device 1 is stably fixed on this mounting bracket. This fixed design ensures the stability and reliability of the image acquisition device 1 during the detection process, avoiding image distortion or data errors caused by vibration or deviation. At the same time, it also provides a clear viewing angle and position for the image acquisition device 1, ensuring the accuracy and consistency of image acquisition.

[0052] The linear light source device 2 is designed to be movably arranged on the mounting bracket. This design enables the linear light source device 2 to adjust its position and angle according to needs to adapt to glass workpieces of different sizes and shapes. By adjusting the irradiation angle and distance of the linear light source device 2, we can better highlight the surface defects of the glass workpiece, improving the detection sensitivity and accuracy. This flexibility not only improves the adaptability of the detection system, but also further enhances its practicality and effect in actual applications.

[0053] Please refer to again Figure 1 and Figure 3 , the mounting bracket equipped with the combined detection system in this embodiment is designed quite precisely and practically. The mounting bracket mainly consists of a bracket 4, a back panel 5 and two side panels 6, which jointly provide stable and adjustable support for the image acquisition device 1 and the linear light source device 2.

[0054] Specifically, the two side plates 6 are spaced apart, and each side plate is fixedly connected perpendicular to the back plate 5, forming a stable frame. The linear light source device 2 is ingeniously designed between the two side plates 6 and can move flexibly therein. This design allows users to adjust the position and angle of the linear light source device 2 according to the detection requirements to optimize the lighting effect and thus improve the detection ability of surface defects of glass workpieces.

[0055] The bracket 4 is fixedly connected to the back plate 5, providing a stable support for the entire mounting rack. The image acquisition device 1, including a camera and a lens, is fixedly arranged on the bracket 4, ensuring that the image of the glass workpiece can be stably captured during the detection process.

[0056] The design of the entire mounting rack not only takes into account stability and adjustability but also fully considers the convenience and safety of operation. Users can easily adjust the positions of the linear light source device 2 and the image acquisition device 1 according to needs to adapt to glass workpieces of different sizes and shapes. At the same time, the structural design of the mounting rack also ensures safety during the operation process, reducing the risk of accidents.

[0057] Please refer again to Figure 1 and Figure 3 , the mounting rack equipped with the combined detection system in this embodiment has a unique and practical design, namely the angle adjustment holes 7. These angle adjustment holes 7 are opened on the side plates 6, facilitating the adjustment of the tilt angle of the linear light source device 2.

[0058] Specifically, both ends of the linear light source device 2 are respectively arranged in the angle adjustment holes 7 through a fastener (such as a bolt, screw, etc.). This design allows users to loosen the fastener, then rotate the linear light source device 2 to adjust its tilt angle towards the glass workpiece, and finally tighten the fastener to fix the adjusted angle. This adjustment method is not only simple and easy to implement but also flexible and variable, capable of adapting to the detection requirements of glass workpieces of different sizes and shapes.

[0059] In addition, the opening positions and quantities of the angle adjustment holes 7 can be designed and adjusted according to actual needs to achieve more precise angle adjustment. This design greatly improves the flexibility and adaptability of the detection system, enabling users to perform detection operations more conveniently.

[0060] Although terms such as image acquisition device and linear light source device are used more frequently in this application, the possibility of using other terms is not excluded. Using these terms is only for more conveniently describing and explaining the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.

[0061] A combined detection system provided by the present utility model can cooperate with an image acquisition device to detect surface defects of a glass workpiece by obliquely arranging a line light source device above the glass workpiece, and can cooperate with the image acquisition device to detect the contour dimensions of the glass workpiece by arranging a backlight device below the glass workpiece, thereby realizing the simultaneous detection of surface defects (such as scratches) and contour dimensions of the glass workpiece, improving the detection efficiency, reducing the detection cost, and being beneficial to ensuring the stability of product quality.

[0062] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of the present application, the patent protection scope of the present application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the substantial concept of the present application and using the content recorded in the text and drawings of the specification of the present application, as well as those directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of the present application.
