Description

Technical Field

[0001] This utility model relates to the technical field of equipment for the production and inspection of empty glass bottles and jars, and in particular to a device for inspecting the concave bottom cracks of empty wine bottles. Background Technology

[0002] Current red wine bottle concave bottom crack inspection devices (such as...) Figure 4 When an empty wine bottle with a concave bottom is intermittently conveyed to the station equipped with a planar light source and a crack inspection camera, it pauses intermittently and rotates. During this time, the planar light source illuminates the crack inspection camera, which continuously takes images for inspection. When the intermittent pause ends, the inspection of one bottle is complete. This cycle repeats, inspecting one bottle after another, thus completing the automatic inspection.

[0003] Current wine bottle concave bottom crack inspection devices are inefficient, capable of inspecting a maximum of about 140 bottles per minute. The main problem lies in the fact that the concave bottom of the bottle is recessed into the bottle's cavity. Light reflected from the cracks on the concave bottom surface undergoes secondary refraction through the bottle's glass before reaching the camera lens, often leading to false detections and false shots, with a false detection rate of 10%. This demonstrates the shortcomings of current wine bottle concave bottom crack inspection devices: low capacity and high false detection rate. This impacts manufacturers' production capacity and wastes societal human and material resources. Therefore, there is an urgent need to develop a new type of wine bottle concave bottom crack inspection device to replace the existing one.

[0004] The purpose of this invention is to solve the problems of low detection efficiency and high false detection rate of traditional empty glass bottle and jar production and inspection equipment. Utility Model Content

[0005] The purpose of this invention is to solve the problems of low detection efficiency and high false detection rate in traditional empty glass bottle and jar production and inspection equipment. This invention adopts the following technical solution:

[0006] A device for inspecting concave bottom cracks in empty wine bottles includes an inspection mechanism and a top light source. The inspection mechanism includes an angle adjustment mechanism located directly below the top light source, and the angle adjustment mechanism is equipped with several inspection cameras.

[0007] As described above, a device for inspecting concave bottom cracks in empty wine bottles includes an angle adjustment mechanism comprising a screw, a long nut sleeved on the screw, the long nut being threadedly connected to the screw, a camera mounting bracket sleeved on the screw, the camera mounting bracket being slidably connected to the screw, at least one connecting bracket hinged to the camera mounting bracket, a camera swing bracket hinged to one side of the connecting bracket, a camera mounting frame mounted on the top of the screw, the camera mounting frame being hinged to one end of the camera swing bracket, and the inspection camera being mounted on one side of the camera swing bracket.

[0008] As described above, in the red wine bottle concave bottom crack inspection device, both the hinged end of the camera fixing bracket and the hinged end of the camera mounting bracket have threaded grooves, and a locking screw is provided in the threaded groove, with the locking screw threadedly connected to the threaded groove.

[0009] As described above, in a red wine bottle concave bottom crack inspection device, a short nut is provided on the outer sleeve of the screw, the short nut is threadedly connected to the screw, and the short nut is located below the long nut.

[0010] As described above, in the red wine bottle concave bottom crack inspection device, a fixing frame is installed at the bottom end of the screw, and the fixing frame is threadedly connected to the screw.

[0011] As described above, in a red wine bottle concave bottom crack inspection device, the camera swing frame is inclinedly disposed between the connecting frame and the camera mounting frame.

[0012] As described above, in a red wine bottle concave bottom crack inspection device, the camera mounting bracket is hinged with six connecting brackets.

[0013] As described above, in a red wine bottle concave bottom crack inspection device, the top end of the screw is provided with a flange for mounting the camera bracket.

[0014] As described above, in the red wine bottle concave bottom crack inspection device, the left-view orthographic projection of the fixing frame is a two-layer stepped shape.

[0015] The red wine bottle concave bottom crack inspection device described above has a ring light source at the top.

[0016] Implementing the embodiments of this utility model has the following beneficial effects:

[0017] 1. In this utility model, the bottle can be conveyed in a straight line without stopping, resulting in high detection efficiency. The light source is located directly above the concave bottom of the empty wine bottle, ensuring that the light directly illuminates the concave bottom surface of the empty wine bottle. This reduces the refraction and scattering of light when passing through the glass of the empty wine bottle, making any tiny cracks on the concave bottom surface more clearly visible. Multiple inspection cameras mounted on the angle adjustment mechanism simultaneously take pictures of the concave bottom of the bottle from different angles to ensure that the entire concave bottom area is covered and that any crack reflections can be captured from the best viewing angle. Simultaneous shooting from multiple angles increases the accuracy and reliability of the detection.

[0018] 2. In this utility model, the operator can adjust the position of the long nut on the screw as needed, so that the camera mounting bracket can move up and down along the screw. By adjusting the hinge point between the connecting bracket and the camera swing bracket, the angle of the inspection camera can be changed, thereby allowing the inspection camera to tilt within a certain range, and further enabling more accurate alignment with different parts of the bottle's concave bottom.

[0019] In summary, this utility model solves the problems of low detection efficiency and high false detection rate of traditional empty glass bottle and jar production and inspection equipment. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 3As shown, this utility model proposes a device for inspecting concave bottom cracks in empty wine bottles, including an inspection mechanism and a top light source 4. The inspection mechanism includes an angle adjustment mechanism 2, which is located directly below the top light source 4. The angle adjustment mechanism 2 is equipped with several inspection cameras 3. When the empty wine bottle with a concave bottom is conveyed in a straight line to the workstation equipped with the top light source 4 and the inspection mechanism, the top light source 4 illuminates the bottle, and the six cameras on the inspection mechanism simultaneously take pictures for inspection. The inspection cameras 3 on the inspection mechanism can observe the concave bottom surface of the empty bottle; therefore, as long as there is a crack reflecting light on the concave bottom surface, the inspection cameras 3 can detect it, resulting in a low miss rate. Also, because the bottle moves in a straight line without interruption, the working efficiency is high. Specifically, a conveyor belt can be used to move the concave-bottomed empty wine bottle in a straight line. When the bottle reaches the inspection position, the top light source 4 projects light onto the bottom of the bottle. Since the light source is directly above the bottle, this ensures that the light directly illuminates the concave bottom surface, reducing refraction and scattering of light as it passes through the glass, making any minute cracks on the concave bottom surface more clearly visible. Multiple inspection cameras 3 mounted on the angle adjustment mechanism 2 simultaneously photograph the concave bottom of the bottle from different angles to ensure coverage of the entire concave area and to capture any reflected light from potential cracks from the optimal viewing angle. Simultaneous multi-angle shooting increases the accuracy and reliability of the inspection.

[0029] Further, as a preferred embodiment of the invention and not a limitation thereof, the angle adjustment mechanism 2 includes a screw 21, a long nut 23 sleeved on the screw 21, the long nut 23 being threadedly connected to the screw 21, a camera mounting bracket 24 sleeved on the screw 21, the camera mounting bracket 24 being slidably connected to the screw 21, at least one connecting bracket 25 hinged to the camera mounting bracket 24, a camera swing bracket 27 hinged to one side of the connecting bracket 25, a camera mounting bracket 26 mounted on the top of the screw 21, the camera mounting bracket 26 being hinged to one end of the camera swing bracket 27, and the inspection camera 3 being mounted on one side of the camera swing bracket 27. The angle adjustment mechanism 2 can adjust the shooting angle of the inspection camera 3 mounted thereon. Specifically, the operator can adjust the position of the long nut 23 on the screw 21 as needed, causing the camera mounting bracket 24 to move up and down along the screw 21. When the camera mounting bracket 24 moves upward, one side of the connecting bracket 25 moves upward; when the camera mounting bracket 24 moves downward, one side of the connecting bracket 25 moves downward. The angle of the inspection camera 3 can be changed by adjusting the hinge point between the connecting frame 25 and the camera swing frame 27, thereby allowing the inspection camera 3 to tilt within a certain range and further enabling it to more accurately align with different parts of the bottle's concave bottom.

[0030] Optionally, in some embodiments, the screw 21 is replaced by a smooth rod body, which is not fitted with a long nut 23. The side wall of the rod body is provided with one of a cylinder, a hydraulic cylinder, or an electric push rod. One end of the cylinder, the hydraulic cylinder, or the electric push rod is fixedly connected to the bottom of the camera mount 24, and the camera mount 24 is slidably connected to the rod body.

[0031] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, both the hinged ends of the camera mounting bracket 24 and the camera mounting bracket 26 have threaded grooves 28, and locking screws 29 are provided in the threaded grooves 28, with the locking screws 29 threadedly connected to the threaded grooves 28. Tightening the locking screws 29 compresses the hinge shafts at one end of the connecting bracket 25 and the camera swing bracket 27. Before adjusting the angle of the inspection camera 3, the relevant locking screws 29 need to be loosened. This can be achieved by rotating the locking screws 29 until they no longer exert pressure on the hinge shafts, allowing the camera swing bracket 27 to adjust its angle freely. After the angle of the camera swing bracket 27 is adjusted, the operator needs to tighten the locking screws 29 until they tightly compress the hinge shafts, preventing the connecting bracket 25 and the camera swing bracket 27 from moving easily, thus completing the angle adjustment of the inspection camera 3.

[0032] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a short nut 22 is fitted over the screw 21, the short nut 22 being threadedly connected to the screw 21, and positioned below the long nut 23. The function of the short nut 22 is to act as a support point, preventing the long nut 23 from loosening due to vibration or other factors. The relative position between the short nut 22 and the long nut 23 determines the lower limit of the movable range of the camera mount 24. This can, to a certain extent, limit the accidental slippage of the long nut 23 and improve the stability of the entire structure.

[0033] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a fixing frame 1 is installed at the bottom end of the screw 21. The fixing frame 1 is threadedly connected to the screw 21, and the left-view orthographic projection of the fixing frame 1 is a two-tiered stepped shape. The fixing frame 1 is used to support the adjustment mechanism 2. The stepped design makes it easier to connect and fix the fixing frame 1 to other equipment or platforms. For example, the fixing frame 1 can be directly fixed to the workbench or frame with screws.

[0034] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the camera swing bracket 27 is obliquely disposed between the connecting bracket 25 and the camera mounting bracket 26, and the camera fixing bracket 24 is hinged to six of the connecting brackets 25. The oblique disposal of the camera swing bracket 27 between the connecting brackets 25 and the camera mounting bracket 26 allows the inspection camera 3 to be better aligned with different areas of the bottle's concave bottom, thereby improving the accuracy of crack detection. The six connecting brackets 25 mean there are six inspection cameras 3, which can simultaneously photograph the bottle's concave bottom from multiple different angles, ensuring comprehensive coverage and improving the accuracy and reliability of crack detection.

[0035] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the top end of the screw 21 is provided with a flange for mounting the camera mounting bracket 26. The flange provides a wider contact surface, allowing the camera mounting bracket 26 to be more securely fixed to the screw 21, reducing displacement caused by vibration or other external forces during the detection process. The flange connection also facilitates disassembly and reinstallation, making routine maintenance or component replacement convenient.

[0036] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the top light source 4 is a ring light source. A ring light source can provide uniform illumination from all directions (360 degrees), ensuring that all areas of the concave bottom of the bottle are fully illuminated, reducing shadows and uneven lighting problems. Uniform light helps enhance the contrast between the crack and the background, making it easier for the inspection camera 3 to capture even minute cracks.

[0037] Example 1:

[0038] A device for inspecting concave bottom cracks in empty wine bottles includes an inspection mechanism and a top light source 4. The inspection mechanism includes an angle adjustment mechanism 2, which is located directly below the top light source 4. The angle adjustment mechanism 2 is equipped with several inspection cameras 3. When the empty wine bottle with a concave bottom is conveyed in a straight line to the workstation equipped with the top light source 4 and the inspection mechanism, the top light source 4 illuminates the bottle, and the six cameras on the inspection mechanism simultaneously take pictures for inspection. The inspection cameras 3 on the inspection mechanism can observe the concave bottom surface of the empty bottle; therefore, as long as there is a crack reflecting light on the concave bottom surface, the inspection camera 3 can detect it, resulting in a low miss rate. Furthermore, because the bottles move in a straight line without interruption, the working efficiency is high. Specifically, a conveyor belt can be used to move the concave-bottomed empty wine bottle in a straight line. When the bottle reaches the inspection position, the top light source 4 projects light onto the bottom of the bottle. Since the light source is directly above the bottle, this ensures that the light directly illuminates the concave bottom surface, reducing refraction and scattering of light as it passes through the glass, making any minute cracks on the concave bottom surface more clearly visible. Multiple inspection cameras 3 mounted on the angle adjustment mechanism 2 simultaneously photograph the concave bottom of the bottle from different angles to ensure coverage of the entire concave area and to capture any reflected light from potential cracks from the optimal viewing angle. Simultaneous multi-angle shooting increases the accuracy and reliability of the inspection.

[0039] The top light source 4 is a ring light source. The ring light source provides uniform 360-degree illumination, ensuring that all areas of the bottle's concave bottom are fully lit, reducing shadows and uneven lighting. Uniform light helps enhance the contrast between the crack and the background, making it easier for the inspection camera 3 to detect even minor cracks.

[0040] The angle adjustment mechanism 2 includes a screw 21, with a long nut 23 sleeved on the screw 21. The long nut 23 is threadedly connected to the screw 21. A camera mounting bracket 24 is sleeved on the screw 21 and slidably connected to the screw 21. At least one connecting bracket 25 is hinged to the camera mounting bracket 24. A camera swing bracket 27 is hinged to one side of the connecting bracket 25. A camera mounting bracket 26 is mounted on the top of the screw 21, and the camera mounting bracket 26 is hinged to one end of the camera swing bracket 27. The inspection camera 3 is mounted on one side of the camera swing bracket 27. The angle adjustment mechanism 2 can adjust the shooting angle of the inspection camera 3 mounted on it. Specifically, the operator can adjust the position of the long nut 23 on the screw 21 as needed, causing the camera mounting bracket 24 to move up and down along the screw 21. When the camera mounting bracket 24 moves upward, one side of the connecting bracket 25 moves upward; when the camera mounting bracket 24 moves downward, one side of the connecting bracket 25 moves downward. The angle of the inspection camera 3 can be changed by adjusting the hinge point between the connecting frame 25 and the camera swing frame 27, thereby allowing the inspection camera 3 to tilt within a certain range and further enabling it to more accurately align with different parts of the bottle's concave bottom.

[0041] Both the hinged ends of the camera mount 24 and the camera mounting bracket 26 have threaded grooves 28, and locking screws 29 are installed in the threaded grooves 28, with the locking screws 29 threadedly connected to the threaded grooves 28. Tightening the locking screws 29 presses against the hinge shafts at one end of the connecting bracket 25 and the camera swing bracket 27. Before adjusting the angle of the inspection camera 3, the locking screws 29 need to be loosened. This can be achieved by rotating the locking screws 29 until they no longer apply pressure to the hinge shafts, allowing the camera swing bracket 27 to adjust its angle freely. After the angle of the camera swing bracket 27 is adjusted, the operator needs to tighten the locking screws 29 until they firmly press against the hinge shafts, preventing the connecting bracket 25 and the camera swing bracket 27 from moving easily, thus completing the angle adjustment of the inspection camera 3.

[0042] A short nut 22 is fitted around the screw 21 and threadedly connected to it. The short nut 22 is positioned below the long nut 23. The short nut 22 serves as a support point, preventing the long nut 23 from loosening due to vibration or other factors. The relative position between the short nut 22 and the long nut 23 determines the lower limit of the camera mount 24's movable range. This limits the accidental slippage of the long nut 23 to a certain extent, improving the overall stability of the structure.

[0043] A fixing frame 1 is installed at the bottom end of the screw 21. The fixing frame 1 is threadedly connected to the screw 21. The left-view orthographic projection of the fixing frame 1 is a two-tiered stepped shape. The fixing frame 1 is used to support the adjustment mechanism 2. The stepped design makes it easier to connect and fix the fixing frame 1 to other equipment or platforms. For example, the fixing frame 1 can be directly fixed to the workbench or frame with screws.

[0044] The camera swing bracket 27 is inclinedly disposed between the connecting bracket 25 and the camera mounting bracket 26, and the camera fixing bracket 24 is hinged to six of the connecting brackets 25. The inclined placement of the camera swing bracket 27 between the connecting brackets 25 and the camera mounting bracket 26 allows the inspection camera 3 to be better aligned with different areas of the bottle's concave bottom, thereby improving the accuracy of crack detection. The six connecting brackets 25 mean there are six inspection cameras 3, which can simultaneously capture images of the bottle's concave bottom from multiple different angles, ensuring comprehensive coverage and improving the accuracy and reliability of crack detection.

[0045] The top end of the screw 21 is provided with a flange for mounting the camera mounting bracket 26. The flange provides a wider contact surface, allowing the camera mounting bracket 26 to be more securely fixed to the screw 21, reducing displacement caused by vibration or other external forces during the testing process. The flange connection method also facilitates disassembly and reinstallation, making it convenient for routine maintenance or component replacement.

[0046] The implementation method of Example 2 is as follows:

[0047] The difference between Embodiment 2 and Embodiment 1 is that the screw 21 is replaced by a smooth rod body, and the rod body does not have a long nut 23 sleeved on it. A cylinder, hydraulic cylinder, or electric push rod is installed on the side wall of the rod body. One end of the cylinder, hydraulic cylinder, or electric push rod is fixedly connected to the bottom of the camera mounting bracket 24, and the camera mounting bracket 24 is slidably connected to the rod body. Preferably, an electric push rod is used. When the electric push rod extends or retracts, it drives the camera mounting bracket 24 to rise and fall, thereby adjusting the angle of the camera swing bracket 27 and the inspection camera 3. Compared to threaded connections, the smooth rod body and electric push rod design simplify the mechanical structure and reduce maintenance difficulty. The electric push rod can achieve fast response and high-precision position control, making it suitable for automated production line applications.

[0048] Specifically, the working principle of this invention is as follows:

[0049] Empty wine bottles move linearly along a conveyor belt. When they reach the inspection position, a ring light source at the top projects uniform 360-degree illumination onto the concave bottom of the bottle. This omnidirectional lighting reduces shadows and uneven lighting, enhances the contrast between cracks and the background, and makes even minute cracks easier to detect.

[0050] Six inspection cameras 3, mounted on the angle adjustment mechanism 2, simultaneously photograph the concave bottom of the bottle from different angles. The angle adjustment mechanism 2 achieves height adjustment via screw 21, long nut 23, and short nut 22, and fine-tunes the angle via connecting bracket 25 and camera swing bracket 27. This multi-angle synchronous shooting ensures comprehensive coverage of the entire concave bottom area, improving the accuracy and reliability of the inspection.

[0051] The height of the camera mount 24 can be finely adjusted by rotating the long nut 23 and the short nut 22, thereby changing the position of the inspection camera 3. The camera swing bracket 27 is tilted between the connecting bracket 25 and the camera mount 26, allowing the operator to fine-tune the angle of the inspection camera 3 as needed. The locking screw 29 is used to lock the hinge point, ensuring the stability and accuracy of the camera position during inspection. The flange design further enhances the stability of the camera mount 26 and facilitates routine maintenance and component replacement.

[0052] In summary, this invention solves the problems of low detection efficiency and high false detection rate of traditional empty glass bottle and jar production and inspection equipment.
