Description

Technical Field

[0001] This invention relates to the field of wine bottle appearance inspection equipment, and more specifically, to a glass wine bottle appearance inspection equipment. Background Technology

[0002] As the core packaging medium for alcoholic beverages, the appearance quality of glass bottles directly impacts brand reputation and consumer experience. Mass production in industrial settings places stringent demands on testing efficiency, accuracy, and stability. Currently, the industry primarily relies on visual inspection for glass bottle appearance. This method suffers from inherent drawbacks such as low efficiency, susceptibility to human fatigue and subjective judgment, and inconsistent standards, making it unsuitable for the demands of high-speed production lines.

[0003] Existing automated inspection solutions still have certain shortcomings. For example, patent number CN117470874A discloses a fully automated glass bottle appearance inspection device based on AI machine vision, which uses a reciprocating conveyor mechanism in conjunction with a front station and five inspection stations to achieve inspection. However, the conveyor mechanism of this solution relies on electric guide rails to connect with the drive plate; jamming is prone to occur when multiple stations operate synchronously; although the camera angle of the inspection station has a fixed setting, it lacks a height adjustment component, making it difficult to adapt to bottles of different heights. At the same time, when inspecting the bottle mouth size, it is easy to cause the edge of the bottle mouth size measurement to be blurry, affecting the accuracy.

[0004] Another technical solution disclosed by patent number CN114441443A uses fixed-position and surrounding camera photography for detection, but it is difficult to completely cover blind spots such as the bottle bottom mold number and cracks in the inner bottom of the bottle.

[0005] In summary, current automated inspection equipment for the appearance of glass bottles suffers from problems such as poor conveying and connection, incomplete inspection coverage, poor adaptability, insufficient accuracy, and limited functionality. There is an urgent need for an automated inspection device that can achieve comprehensive, high-precision, highly adaptable, and functionally integrated capabilities to meet the dual demands of industrial production for quality control and efficiency improvement.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0050] like Figure 1 As shown, the present invention provides a glass bottle appearance inspection device, comprising a feeding mechanism 1, a first rotary conveyor mechanism 2, a weighing mechanism 3, a second rotary conveyor mechanism 4, a third rotary conveyor mechanism 5, and an output mechanism 6 arranged sequentially in the inspection sequence. After entering the device through the feeding mechanism 1, the bottle flows sequentially through the first rotary conveyor mechanism 2, the weighing mechanism 3, the second rotary conveyor mechanism 4, and the third rotary conveyor mechanism 5, and is output by the output mechanism 6 after completing the entire inspection process. Each rotary conveyor mechanism clamps different parts of the bottle according to its assigned function and drives them to rotate, cooperating with the corresponding inspection station to achieve accurate inspection. The mechanisms are smoothly connected, avoiding conveying jams, and simultaneously achieving layered inspection of upper section defects, lower section defects, and dimensional defects.

[0051] like Figure 2 As shown, the turntable conveying mechanism 2 has multiple lower clamping components 18 arranged circumferentially. These lower clamping components 18 hold the lower section of the bottle and can drive the bottle to rotate. The turntable conveying mechanism has multiple upper section defect detection stations on its outer periphery. The lower clamping components 18 are evenly distributed circumferentially. After clamping the lower section of the bottle, they drive the bottle to rotate 360°. During the rotation, they work in conjunction with the upper section defect detection stations on the outer periphery to complete multi-dimensional imaging and inspection.

[0052] like Figure 3 As shown, the turntable conveying mechanism 4 has multiple upper clamping components 19 arranged circumferentially. These upper clamping components 19 clamp the upper section of the bottle and can drive the bottle to rotate, keeping the bottle suspended in the air. Multiple defect detection stations for the lower section of the bottle are located on the outer periphery of the turntable conveying mechanism 4. The upper clamping components 19 clamp the upper section of the bottle, suspending the lower section, and while driving the bottle to rotate, the outer detection stations perform omnidirectional imaging and inspection of the lower section and the bottom of the bottle.

[0053] In the above scheme, after the turntable conveyor mechanism 1 2 and the turntable conveyor mechanism 2 4 rotate to the corresponding detection station, they stop briefly, and then their respective clamping parts rotate one full circle in place to achieve 360° all-round detection, while also realizing the clamping connection between the conveying mechanisms.

[0054] like Figure 4 As shown, the turntable conveyor mechanism 3 5 has multiple glass conveying positions 20 circumferentially embedded. After the wine bottle enters the turntable conveyor mechanism 3 5, it is located on the glass conveying position 20. Multiple wine bottle size defect detection stations are set in the area where the turntable conveyor mechanism is located. After the wine bottle is placed into the glass conveying position 20 by the lower clamping component 18, the limiting block restricts its position, and it is conveyed to the size detection station by the turntable. With the help of a camera and light source, various size parameters are detected. Due to the transparency of glass, the bottom outline of the wine bottle can be clearly photographed from the bottom of the glass, which meets the size detection requirements. Similar to the turntable conveyor mechanism 1 2 and the turntable conveyor mechanism 2 4, it stops briefly after rotating to the corresponding detection station.

[0055] like Figures 5-6 As shown, both the feeding mechanism 1 and the discharging mechanism 6 include a rotating component 7, a translation component 8 mounted on the rotating component 7, a liftable mounting bracket 10 mounted on the movable base 9 of the translation component 8, and an adjustment component for adjusting the height of the mounting bracket 10.

[0056] The rotating component 7 adjusts the feeding and discharging directions, and the translation component 8 moves the mounting bracket 10 to the designated position to adjust the material picking and unloading positions, thereby better connecting the front and rear workstations. The adjustment component adjusts the height of the mounting bracket 10 according to the bottle specifications to achieve precise feeding and discharging.

[0057] like Figure 5 As shown, a set of electric grippers 11 are installed at each end of the mounting bracket 10. The two sets of electric grippers 11 alternately feed material to the turntable feeding mechanism 2. When the bottle is above the upper clamping member 19 during feeding, the adjustment component drives the mounting bracket 10 to move down so that the bottle is located in the clamping area of ​​the upper clamping member 19.

[0058] Taking the feeding structure as an example, the two sets of electric grippers 11 move alternately. One set clamps the wine bottle and moves it above the turntable feeding mechanism 2. The adjustment component drives the support to move down and sends the wine bottle into the clamping range of the lower clamping part 18 before releasing it. The other set simultaneously picks up the material to prepare for the next feeding.

[0059] like Figures 5-6 As shown, the adjustment assembly includes an adjustment cylinder 12, an adjustment plate 13 installed at the output end of the adjustment cylinder 12, an adjustment seat 14 corresponding to the adjustment plate 13, and an adjustment block 15 installed on the adjustment seat 14. The adjustment seat 14 is installed on the mounting bracket 10. A guide pin 16 penetrating the mounting bracket 10 is installed on the movable base 9. A return spring 17 is sleeved on the guide pin 16. The return spring 17 is located between the movable base 9 and the mounting bracket 10.

[0060] Alternating feeding design improves feeding efficiency, avoids feeding wait, and adjustable components precisely control the bottle placement position, ensuring clamping stability and reducing feeding errors.

[0061] like Figures 5-6 As shown, the material feeding path between the feeding mechanism 1 and the turntable conveying mechanism 2 is further provided with a pre-feeding inspection station 21 and an inspection station 22. The inspection station 21 includes a coaxially arranged area array camera 211 and a light source 212. The light source 212 is a ring light source, and the area array camera 211 vertically upwards to photograph the bottom of the bottle.

[0062] In the above scheme, inspection station 21 mainly detects the bottle bottom mold number and markings, and orients the bottle. After image processing, the current position and angle of the bottle are determined, and the bottle is further adjusted to the target position by a mechanical structure before entering the equipment. The area array camera 211 is a flying camera that takes pictures during the bottle's movement, saving inspection time. The illumination principle of the ring light source is mainly based on a symmetrical LED array arrangement and diffuse reflection optical design. Its core structure consists of multiple sets of LEDs arranged concentrically, forming a uniform axial illumination beam through precise optical path control. After diffuse reflection on the working surface, the incident light is received and imaged by a lens located along the central axis of the ring light source, highlighting the object's edges and surface texture features. This illumination method uses a programmable controller to adjust the emission angle and light intensity ratio, achieving adaptive illumination optimization for different tested objects.

[0063] The second detection station 22 includes a coaxially arranged area array camera 221, a second light source 222, and a third light source 223. The second light source 222 and the third light source 223 are located on the upper and lower sides of the wine bottle, respectively. The area array camera 221 takes pictures of the inner bottom of the wine bottle perpendicular to the bottle mouth. The second light source 222 is a blue open-aperture surface light source, and the third light source 223 is a red circular surface light source.

[0064] In the above scheme, inspection station 22 mainly detects defects such as black spots, dirt, white spots, cracks, and foreign objects on the inner bottom; among them, area array camera 221 is a flying camera that takes pictures during the movement of the wine bottle, saving inspection time. Blue light has a shorter wavelength, weaker diffraction effect, and stronger light particle properties, thus it has a stronger ability to depict details and detect the details of objects; red light has a longer wavelength and relatively higher penetrating power than other wavelengths, making it more suitable for internal inspections that require penetrating the surface.

[0065] The defect detection station on the upper section of the wine bottle includes detection station 3 (23), detection station 4 (24), and detection station 5 (25) arranged sequentially along the wine bottle conveying path.

[0066] like Figure 7 As shown, the detection station 3 23 includes five area array cameras and a backlight source 4 236. The five area array cameras are arranged in sequence from area array camera 3 231 to area array camera 7 235. The five area array cameras and the light source 4 236 are distributed on both sides of the bottle. Area array camera 3 231 is positioned diagonally above the bottle at an angle of 60-80° with the horizontal plane, taking pictures of the bottle shoulder and neck. Area array camera 4 232 is also positioned diagonally above the sample at an angle of 50-70° with the horizontal plane, taking pictures of the upper part of the bottle. Area array camera 5 233 takes pictures of the upper part of the bottle horizontally, area array camera 6 234 takes pictures of the upper middle part of the bottle horizontally, and area array camera 7 235 takes pictures of the lower middle part of the bottle horizontally. During the rotation of the bottle, area array cameras 3 231 to 7 235 take multiple frames.

[0067] In the above scheme, inspection station 323 mainly inspects, but is not limited to, the bottle mouth, shoulder, body, and bottom areas, detecting defects such as uneven coloring, dirt, bubbles, black spots, stones, rust, and flat bottoms. The backlight uses LED beads as the light-emitting core. The light first enters a diffuser plate, which uses microbeads or a frosted structure to scatter the light multiple times, eliminating bright and dark stripes and light spots from the light source. This homogenizes and converts the light energy of the point source into a planar form. Through light scattering, diffuse reflection, and uniform optical design, the light is emitted uniformly from a two-dimensional plane. The uniform white background facilitates defect detection.

[0068] like Figure 8As shown, the detection station 4 24 includes six area array cameras and three area light sources. The six area array cameras are, in order, area array camera 8 241 to area array camera 13 246, and the three area light sources are, in order, light source 5 247 to light source 7 249. Area array camera 8 241 is positioned diagonally above the bottle with an angle of 50-70° to the horizontal plane, and is used in conjunction with light source 5 247 to capture the bottle mouth from above. Area array camera 9 242 is positioned diagonally below the sample with an angle of 40-60° to the horizontal plane, and is used in conjunction with light source 5 247 to capture the bottle neck from below. Area array camera 10... Camera 243 is positioned diagonally below the bottle at an angle of 50-70° to the horizontal plane, and uses light source 6 (248) to shoot the bottle opening from above; Camera 11 (244) is positioned diagonally above the bottle at an angle of 40-60° to the horizontal plane, and uses light source 6 (248) to shoot the bottle neck from above; Camera 12 (245) uses light source 7 (249) to shoot the upper middle part of the bottle horizontally; Camera 13 (246) uses light source 8 (255) to shoot the lower middle part of the bottle horizontally; Camera 8 (241) to 13 (246) take multiple frames during the bottle's rotation.

[0069] In the above scheme, inspection station 4 24 mainly inspects, but is not limited to, the bottle mouth and shoulder, detecting structural defects such as cracks. The area array cameras 8 241 to 11 244 and the light source 6 248 are mounted on the same height adjustment component 32. According to the height specifications of the wine bottle, the height of the area array cameras 8 241 to 11 244 and the light source 6 248 are adjusted synchronously through the height adjustment component 32 so that the camera's shooting angle is always aimed at the bottle mouth and neck area, thus adapting to the inspection of the bottle mouth and neck of wine bottles of different specifications.

[0070] like Figure 9 As shown, the detection station 5 25 includes four area array cameras and a light source 8 255 that provides striped backlighting. The four area array cameras are arranged in sequence as area array camera 14 251 to area array camera 17 254. The four area array cameras and the light source 8 255 are respectively distributed on both sides of the bottle. Area array camera 14 251 is placed diagonally above the sample and at an angle of 50-70° with the horizontal plane, shooting the shoulder of the bottle from above. Area array camera 15 252 shoots the upper part of the bottle horizontally. Area array camera 16 253 shoots the upper middle part of the bottle horizontally. Area array camera 17 254 is placed on one side of the sample and shoots the lower middle part of the bottle horizontally. During the rotation of the bottle, area array cameras 14 251 to 17 254 take multiple frames.

[0071] In the above scheme, inspection station 525 mainly inspects, but is not limited to, the bottle mouth, bottle shoulder, bottle body, and bottle bottom areas, detecting structural defects such as bubbles, stones, wrinkles, ripples, cold plates, and washboards. The striped backlight not only has the characteristics of backlighting but also features alternating black and white stripes. Through projection, it produces alternating black and white stripes on the object, creating a contrast between light and dark, highlighting defect features, and facilitating defect detection; the stripe spacing and arrangement can be adjusted according to actual conditions.

[0072] like Figure 1As shown, the weighing mechanism 3 includes a weighing support, and the upper clamping component 19 clamps the wine bottle on the turntable conveying mechanism 2 and places it on the weighing support for weighing; the sample is placed on the weighing support for static weighing, and then clamped by the upper clamping component 19 to enter the next testing station.

[0073] The defect detection station for the lower section of the wine bottle includes detection station 626, detection station 727 and detection station 828, which are set up sequentially along the wine bottle conveying path.

[0074] like Figure 10 As shown, the inspection station 6 26 includes area array camera 18 261, area array camera 19 262, light source 9 263, and light source 10 264. Light source 9 263 is a surface light source, and light source 10 264 is a striped surface light source. Area array camera 18 261 is paired with light source 9 263 to horizontally photograph the bottom of the bottle. Area array camera 19 262 is paired with light source 10 264 to horizontally photograph the bottom of the bottle from another position. During the bottle's rotation, area array cameras 18 261 and 19 262 capture multiple frames. Inspection station 6 26 primarily inspects, but is not limited to, the lower area of ​​the bottle, detecting defects such as inclusions, dirt, bubbles, black spots, stones, rust, and flat bottoms.

[0075] like Figure 11 As shown, the detection station 7 27 includes seven area array cameras and a light source 11 278 that provides area light. The seven area array cameras are arranged in sequence as area array camera 20 271 to area array camera 26 277; area array camera 20 271 vertically upwards to photograph the bottom of the bottle; area array camera 21 272 at an angle of 50-70° to the horizontal plane, photographing the bottom of the bottle from below; area array camera 22 273 at an angle of 30-50° to the horizontal plane, photographing the bottom of the bottle from below; area array camera 23 274 at an angle of 50-70° to the horizontal plane... Cameras are positioned at an angle of 30-50° to the horizontal, shooting from below the bottom of the bottle. Cameras 24 (275) and 25 (276) are also positioned at an angle of 30-50° to the horizontal, shooting from below the bottom of the bottle, and are distributed around the bottle's perimeter along with cameras 21 (272) and 24 (275). Camera 26 (277) is positioned outside light source 11 (278) at approximately a 2° angle to the horizontal, shooting the bottom of the bottle's side. Multiple frames are captured by cameras 20 (271) to 26 (277) during the bottle's rotation. Inspection station 7 (27) primarily inspects, but is not limited to, the bottle body and bottom area, detecting structural defects such as cracks and bubbles. The multi-angled cameras allow for multi-directional shooting, increasing inspection accuracy.

[0076] like Figure 12As shown, the inspection station 828 includes five area array cameras and two area light sources. The five area array cameras are arranged in sequence from area array camera 27281 to area array camera 31285, and the two area light sources are light source 12286 and light source 13287. Area array camera 27281 is at an angle of 30-50° to the horizontal plane, shooting the bottle from above; area array camera 282 is at an angle of 10-30° to the horizontal plane, shooting the bottle from above; area array camera 29283 is shooting the side of the bottle horizontally; area array camera 30284 is at an angle of 10-30° to the horizontal plane, shooting the bottle from below; area array camera 31285 is at an angle of 30-50° to the horizontal plane, shooting the bottle from below; light source 12286 illuminates the bottom of the bottle vertically upwards, and light source 13287 illuminates the bottom of the bottle from the side of the bottle; light source 12286 and light source 13287 are orthogonal. Inspection station 828 mainly inspects, but is not limited to, the bottle body area, detecting structural defects such as cracks.

[0077] The bottle size defect detection station includes detection station 29 and detection station 30, which are set up sequentially along the bottle conveying path.

[0078] like Figure 13 As shown, the detection station 9 29 includes three area array cameras, one ring light source, and one parallel area light source. The three area array cameras are designated as area array camera 32 291 to area array camera 34 293 in sequence. The ring light source is designated as light source 14 294, and the parallel area light source is designated as light source 15 295. Area array camera 32 291, in conjunction with light source 14 294, vertically downwards photographs the inner and outer diameter dimensions of the bottle mouth. Area array camera 33 292, in conjunction with light source 14 294, vertically upwards photographs the outline dimensions of the bottle bottom. Area array camera 33 292 is located directly below the glass conveying station 20, which is equipped with a limiting block to restrict the position of the bottle. Area array camera 34 293, in conjunction with light source 15 295, horizontally photographs the bottle mouth position to detect the bottle mouth edge thickness.

[0079] In the above scheme, inspection station 29 mainly detects, but is not limited to, defects such as bottle height, rim thickness, inner and outer diameters of the bottle mouth, and bottom contour. Light source 294 is a ring light source. Its incident light undergoes diffuse reflection on the sample surface and is then received and imaged by a lens located along the central axis of the ring light source, highlighting the object's edges and surface texture features. The programmable controller adjusts the emission angle and light intensity ratio to achieve adaptive lighting optimization for different test objects. When used with a telecentric lens, stability and accuracy can be further improved, and environmental stray light interference can be further reduced.

[0080] In certain scenarios, surface light sources often fail to achieve the desired effect, primarily because light rays interfere with each other at the edges of objects, resulting in blurred edges and low reliability for high-precision measurements. Therefore, in the application of light sources, it is necessary to choose backlights with more consistent light emission directions, i.e., parallel backlights.

[0081] The Light Source 15295 is a parallel backlight source, which provides a more uniform light emission direction. This eliminates edge blurring caused by diffuse reflection, resulting in clear and sharp images, improving measurement accuracy and contrast (enhancing the contrast of the edge contours of the object being detected in the system). It also eliminates boundary effects (diffuse reflection from backlighting causes light to be reflected onto the sides of the object, making it appear smaller than it actually is; parallel light reduces this reflection phenomenon). Therefore, it is very suitable for detecting objects with curved contours. When used with a telecentric lens, it can further improve stability and accuracy, and also further reduce interference from stray light from the environment.

[0082] like Figure 13 As shown, the inspection station 30 includes two area array cameras, a ring light source, and a parallel area light source. The two area array cameras are designated as area array camera 35 301 to area array camera 36 302 in sequence. The ring light source is designated as light source 16 303, and the parallel area light source is designated as light source 17 304. Area array camera 35 301, in conjunction with light source 16 303, vertically downwards photographs the diameter of the anti-slip teeth 33 at the bottle mouth. Area array camera 36 302, in conjunction with light source 17 304, horizontally photographs the bottle neck position to detect the bottle neck dimensions. Inspection station 30 mainly detects, but is not limited to, defects such as the anti-slip teeth 33 at the bottle mouth and the bottle neck dimensions.

[0083] like Figures 13-14 As shown, both inspection station 29 and inspection station 30 further include a movable background structure 31. The movable background structure 31 includes a lifting component 311, a background plate gripper 312 mounted on the lifting component 311, and a background plate 313 mounted on the background plate gripper 312 and provided with a semi-circular notch. During shooting, the background plate gripper 312 is clamped at the bottle mouth and the clamping part is located below the anti-slip teeth 33 at the bottle mouth. The area scan camera 291 and the light source 294, as well as the area scan camera 301 and the light source 303, are raised and lowered synchronously with the background plate gripper 312.

[0084] Before shooting, the lifting assembly 311 drives the background plate gripper 312 to hold the bottle neck, with the semi-circular notch conforming to the contour of the bottle neck. The background plate 313 provides a uniform shooting background, reducing interference from ambient stray light. The camera and light source rise and fall synchronously with the gripper, adjusting to the optimal shooting height before taking the shot. After shooting, the background plate gripper 312 releases its grip on the bottle neck, and the lifting assembly 311 drives it to rise, avoiding interference with the movement of the bottle. The background plate 313 is white and can be made of polytetrafluoroethylene (PTFE).

[0085] This glass bottle appearance inspection equipment utilizes rotating conveyor mechanisms that clamp and rotate different parts of the bottle according to their respective functions. These mechanisms work in conjunction with corresponding inspection stations to achieve precise inspection. The smooth integration of these mechanisms prevents conveying blockages and enables layered inspection of defects at different levels, including upper, lower, and dimensional defects, thus improving both efficiency and accuracy. Multiple cameras and multi-angle sensors, combined with a customized light source and rotating multi-frame shooting and rapid-fire shooting modes, accurately identify various defects such as cracks and bubbles. The inspection standards are consistent and free from subjective human error.
