[0001] The invention belongs to the technical field of glass bottle detection, and in particular relates to a non-rotating glass bottle crack detection device and a detection method thereof. Background Art

[0002] During the production process of glass bottles, in order to detect whether the finished glass bottles have defects such as cracks, the glass bottles need to be inspected. In order to improve the inspection efficiency and the accuracy of the inspection results, the existing technical solutions generally use comprehensive inspection machines to detect cracks in glass bottles.

[0003] The structures of comprehensive inspection machines of various manufacturers are basically the same. They all rotate the glass bottle 1.5 circles in a star wheel. During the rotation of the glass bottle, the cracks in the glass bottle are detected by camera or photoelectric detection.

DETAILED DESCRIPTION

[0021] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0022] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] In one embodiment, the present invention provides a crack detection device.

[0024] like Figure 1 As shown, the crack detection equipment includes a conveyor line 1 for continuously transporting glass bottles and a bracket 6 located above the conveyor line 1. On one side of the input end of the conveyor line 1, a detection camera (not shown in the figure) facing the glass bottles is installed to obtain the bottle height information of the glass bottles to be inspected. Along the conveying direction of the conveyor line 1, a first detection component 10 and a second detection component 11 are sequentially arranged at the bottom of the bracket 6. The first detection component 10 is used to detect vertical cracks at the mouth of the glass bottle, and the second detection component 11 is used to detect transverse cracks at the mouth of the glass bottle, and at the same time supplement the secondary detection of vertical cracks, so as to make the detection more comprehensive. A detection bracket 3 is set above the conveyor line 1, and the bracket 6 realizes vertical movement through a driving component arranged on the detection bracket 3, so as to adjust the distance between the detection component and the glass bottle.

[0025] The driving assembly includes a screw lift 4, and four screw lifts 4 are respectively fixed at the four corners of the top of the detection bracket 3. The screws 2 of the four screw lifts 4 pass through the screw nuts at the four corners of the top of the bracket 6 to form a rigid lifting mechanism. The four screw lifts 4 are paired in pairs, and the two adjacent groups of screw lifts 4 are connected by a coupling to form a lifting group, totaling two groups. A first synchronous wheel 9 is installed at one end of one of the lifting groups, and a servo motor 8 is mounted at the other end. A second synchronous wheel 5 is installed at one end of the other lifting group, and the second synchronous wheel 5 is linked to the first synchronous wheel 9 through a synchronous belt 7. When the servo motor 8 is started, the four screw lifts 4 are lifted and lowered synchronously, thereby ensuring the stability of the bracket 6 during the lifting process.

[0026] like Figures 2 to 5 As shown, the first detection assembly 10 includes a tray 12, a light source module 14 and a first industrial camera 15. The tray 12 is fixed to the bottom of the bracket 6, providing a stable installation platform. Eight sets of light source modules 14 are evenly surrounded on the bottom inner edge of the tray 12, and eight first industrial cameras 15 are evenly surrounded on the top outer edge of the tray 12 through a retaining frame 13, forming a circular array of "light source-camera-light source" alternately arranged.

[0027] The first industrial camera 15 on the holder 13 is installed obliquely downward, facing the bottle mouth area of ​​the glass bottle, and the angle β between the main optical axis and the horizontal plane is 1 Set to 10±0.5°. It can ensure sufficient oblique viewing angle to reduce motion blur (conveyor line 1 continuously conveys glass bottles) and environmental reflections, while not losing too much detail information due to excessive angles, ensuring full capture of bottle mouth details and avoiding blind spots. In conjunction with light source module 14, the oblique viewing angle can better utilize light, highlight defect features, and improve recognition rate.

[0028] The light source module 14 includes a clamping seat 17, which is fixed to the bottom of the tray 12. Two sets of parallel point light sources 16 are installed obliquely upward at the lower end of the clamping seat 17. The point light sources 16 illuminate the bottle mouth area of ​​the glass bottle. The angle α between the radiation axis of the point light source 16 and the horizontal plane is 1 It is 10±0.5°.

[0029] Angle α 1 The low-angle incident light path formed can ensure that the light hits the surface of the glass bottle at a suitable angle. For vertical cracks, low-angle light can amplify its bright line features. This is because the angle between the vertical crack and the incident direction of the light is large, causing the scattered light to be more concentrated in the crack area, thus forming a clear bright line feature in the image. At the same time, low-angle incident light can reduce the vertical collision between the light and the surface of the glass bottle, thereby reducing the impact of specular reflection and improving detection accuracy.

[0030] The projection angle λ between the radiation axis of any point light source 16 and the main optical axis of the adjacent first industrial camera 15 on the vertical plane is 20±0.5°. This angle design enables the camera to effectively capture the crack morphology of the irradiated area and avoid overexposure or shadow blind spots caused by overlapping light paths. 2 The angle of the two point light sources 16 on the same light source module 14 is parallel, and the spacing L is d±5mm (d is the maximum outer diameter of the bottle mouth), which can avoid light overlap and overexposure, and eliminate dark areas at the edges.

[0031] like Figures 6 to 8As shown, the second detection assembly 11 includes a detection tray 18, a second industrial camera 21, a first arc support frame 22 and a second arc support frame 23. A surface light source 20 is hoisted at the bottom center of the detection tray 18, and a group of arc light sources 19 are hoisted on both sides of the surface light source 20, and the position height of the arc light source 19 is lower than the position height of the surface light source 20. The surface light source 20 vertically illuminates the top area of ​​the bottle mouth, and the arc light source 19 illuminates the side area of ​​the bottle mouth horizontally. There are a total of sixteen second industrial cameras 21, and four groups of first arc support frames 22 and second arc support frames 23 are each provided. Four groups of first arc support frames 22 and four groups of second arc support frames 23 are evenly and alternately surrounded by the bottom outer edge of the detection tray 18 to form a circular array. This arrangement ensures that the camera can shoot the glass bottle from multiple angles, thereby capturing more detailed information.

[0032] Sixteen second industrial cameras 21 are arranged in a three-layer structure arranged vertically, and the cameras in each layer are kept at the same height to ensure the consistency of the shooting images. On the first layer, four second industrial cameras 21 are installed at the top of four groups of first arc-shaped support frames 22. On the second layer, a second industrial camera 21 is installed in the middle of each group of first arc-shaped support frames 22 and second arc-shaped support frames 23, totaling eight. On the third layer, four second industrial cameras 21 are installed at the bottom of four groups of first arc-shaped support frames 22. These sixteen second industrial cameras 21 are arranged alternately in a "3-1-3" manner, forming an efficient and precise ring camera array.

[0033] All second industrial cameras 21 are installed obliquely downward to illuminate the bottle mouth area. The angle β between the main optical axis of the first layer of second industrial cameras 21 and the horizontal plane 4 is 40±0.5°, and the angle β between the main optical axis of the second industrial camera 21 on the second layer and the horizontal plane 5 is 30±0.5°, and the angle β between the main optical axis of the second industrial camera 21 on the third layer and the horizontal plane 3 The main optical axes of all second industrial cameras 21 converge at a point in the bottle mouth area to form a stereo imaging focus, and combined with multi-view image fusion technology (such as 3D point cloud reconstruction), the crack depth and spatial distribution are accurately located.

[0034] The projection angle β of two adjacent second industrial cameras 21 on the first arc-shaped support frame 22 on the vertical plane 2 The angle of the first arc support frame 22 is 10±0.5°, and through precise angle control, seamless splicing is achieved to eliminate detection blind spots. The specifications of the first arc support frame 22 and the second arc support frame 23 are consistent, and the center of the two is located at the intersection of the radiation axis of the second industrial camera 21. This design can ensure the geometric symmetry between the second industrial camera 21 and the light source, and avoid field of view offset or image distortion caused by mechanical installation deviation. It can also adapt to the curved surface characteristics of the glass bottle to improve imaging uniformity.

[0035] In another embodiment, based on the above crack detection device, the present invention provides a non-rotating glass bottle crack detection method.

[0036] S1. Height adjustment The installation positions and angles of all cameras and light sources are fixed and do not need to be adjusted. By detecting the real-time feedback of the camera, the servo motor 8 is started to drive the four screw lifts 4 to rise and fall synchronously, and the first detection component 10 and the second detection component 11 under the bracket 6 are automatically adjusted to the preset height.

[0037] This step ensures that the camera and light source can capture and illuminate the glass bottles at the most appropriate distance, thereby improving the accuracy and reliability of detection.

[0038] S2. Vertical crack detection The glass bottles on the conveyor line 1 are sent to the first detection component 10. When the sensor under the first detection component 10 detects the glass bottles, one of the first industrial cameras 15 is triggered to take pictures, and the light source modules 14 on both sides are linked to the camera shutters and are lit synchronously. Every time the glass bottle moves 2mm, the first industrial camera 15 takes pictures in a clockwise or counterclockwise order. After the shooting is completed, the system converts the original RGB image into a grayscale image, and determines the vertical crack characteristics after feature extraction. If multiple cameras shoot at the same time, adjacent light sources may overlap at an angle to form cross shadows or reflective interference on the surface of the bottle, covering up fine cracks.

[0039] like Fig. 9 As shown, vertical cracks form obvious narrow and long bright line features in the image.

[0040] S3, first removal of defective products According to the detection result of the first detection component 10 , the first rejection component arranged at one side of the first detection component 10 rejects the defective glass bottles, and the qualified glass bottles continue to flow to the second detection component 11 .

[0041] S4. Transverse crack detection When the sensor under the second detection component 11 detects a glass bottle, the surface light source 20 lights up, and the four second industrial cameras 21 on the first layer and the eight second industrial cameras 21 on the second layer take pictures at the same time. After the shooting is completed, the system converts the original RGB image into a grayscale image, and determines the transverse crack characteristics after feature extraction.

[0042] like Fig.10 As shown, the transverse crack forms an obvious narrow and long bright line feature in the image.

[0043] S5. Secondary vertical crack detection After the second industrial cameras 21 on the first and second layers have finished taking pictures and the glass bottle has advanced 10 mm, the arc light source 19 on the left side of the surface light source 20 is first lit, and the two groups of second industrial cameras 21 on the third layer (on the same side as the lit arc light source 19) shoot at the same time. After the glass bottle advances 10 mm again, the arc light source 19 on the right side of the surface light source 20 is then lit, and the other two groups of second industrial cameras 21 on the third layer shoot at the same time. The system will perform grayscale conversion on the captured image to identify the vertical crack features. Horizontal crack detection uses the surface light source 20 for uniform illumination, while vertical cracks rely on the lateral fill light of the arc light source 19. If the left and right arc light sources 19 are lit at the same time, cross reflections or shadow overlap may occur due to angle differences, covering up the subtle crack features.

[0044] S6. Second elimination of defective products According to the detection result of the second detection component 11, the second rejection component arranged at one side of the second detection component 11 rejects the defective glass bottles.

[0045] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
