Description

Technical Field

[0001] This utility model relates to the technical field of image detection devices for wine bottle quality, specifically a mechanism for detecting image defects on the outer periphery of a bottle. Background Technology

[0002] In the production process of wine bottles, defect detection is a crucial step affecting the quality of the finished product. Currently, defect detection of wine bottles is usually carried out using image processing technology. For example, the applicant's previous application document with application number 202321646308.4 disclosed a device for detecting neck cracks in a glass bottle. This device uses a bottle-clamping belt to move the glass bottle and uses a detection camera to complete the image acquisition of the neck area, ultimately completing the detection of neck defects. However, this detection method is only suitable for image acquisition of the neck or mouth area. Due to the interference of the bottle-clamping belt, it is difficult to acquire image information of the bottle body. Furthermore, the method of driving the glass bottle through the bottle-clamping belt requires a high clamping force. When the clamping force is too large, it is difficult for the glass bottle to enter between the two bottle-clamping belts. When the clamping force is too small, the glass bottle is easy to fall between the two bottle-clamping belts, thus hindering the image acquisition process. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a bottle body peripheral defect image detection mechanism.

[0004] The technical solution of this utility model is as follows:

[0005] A bottle peripheral defect image detection mechanism includes a horizontally arranged fixed plate. A support device and an image acquisition device are provided on the upper side of the fixed plate. The support device can complete the support and positioning of the bottle, and the image acquisition device can complete the acquisition of overall image information of the bottle, and finally complete the defect detection of the bottle.

[0006] As the core technical concept of this utility model, the supporting device includes a supporting unit, which includes a turntable rotatably mounted on the upper side of a fixed plate and capable of supporting the wine bottle. A drive motor is connected to the lower side of the turntable to drive its rotation. The wine bottle can be placed on the turntable and, under the action of the drive motor, rotates around a vertical axis. The image acquisition device is configured to periodically acquire several images of the wine bottle during its rotation. Furthermore, since the image acquisition is performed on the turntable, the wine bottle remains more stable during image acquisition. Because the image acquisition is performed during the bottle's rotation, the image acquisition device can completely capture the overall image information of the outer ring of the wine bottle, ensuring the accuracy of the wine bottle defect detection.

[0007] As described above, in order to ensure the stability of the bottle when the turntable rotates, and thus ensure the accuracy and clarity of image acquisition, a preferred embodiment of the bottle outer peripheral defect image detection mechanism is provided with grippers on opposite sides of the turntable, and the bottle can be stably fixed on the turntable by the grippers.

[0008] As a further preferred embodiment, to further ensure the gripper's fixing effect on the wine bottle, the two grippers are arc-shaped structures with opposite openings.

[0009] As described above, a bottle peripheral defect image detection mechanism includes multiple linearly arranged support units. The image acquisition device includes multiple image acquisition units corresponding to the support units. A transfer device is also provided on one side of the support device, capable of moving the bottle from the first support unit to the next support unit in a step-by-step manner. Based on this structure, multiple image acquisition units can collect image information from different positions of the bottle. That is, after the image acquisition unit corresponding to the first support unit completes its image acquisition, the transfer device can move the bottle to the next support unit and continue to collect image information from different positions of the bottle through the image acquisition units. The step-by-step transfer method, combined with the multiple support units and image acquisition units, ensures that the defect detection of the bottle can be carried out sequentially and efficiently.

[0010] Specifically, the image acquisition device includes a first image acquisition unit corresponding to one of the support units. The first image acquisition unit includes a first planar light source located above the support unit and illuminating downwards in the opposite direction. The planar light source can provide supplementary lighting to the bottle from top to bottom. A first camera is also provided on the outside of the first planar light source, tilted downwards and capable of acquiring image information of the bottle mouth and bottle shoulder, so as to finally realize the detection of defects (cracks and / or gaps) at the bottle mouth and bottle shoulder.

[0011] Furthermore, the image acquisition device also includes a second image acquisition unit corresponding to one of the support units. The second image acquisition unit includes a point light source, which is configured to shine light into the interior of the bottle, thereby making the entire bottle glow. The second image acquisition unit also includes a second camera capable of acquiring image information of the outer wall of the bottle. Through the work of the second camera in conjunction with the point light source, the detection of defects on the outer wall of the bottle is realized.

[0012] In a preferred embodiment, the second image acquisition unit further includes a third camera capable of acquiring bottleneck image information. Through the operation of the third camera and a point light source, the detection of defects at the bottleneck position of the wine bottle is achieved.

[0013] Furthermore, the image acquisition device also includes a third image acquisition unit corresponding to one of the support units. The third image acquisition unit includes a second planar light source located outside the support unit, which is configured to horizontally illuminate the upper outer part of the bottle. In addition, the third image acquisition unit also includes a fourth camera capable of acquiring image information of the bottle mouth, thereby realizing the detection of defects (burst and / or riser) at the bottle mouth.

[0014] In a preferred embodiment, the third image acquisition unit also includes a fifth camera capable of acquiring image information of the outer edge of the bottle opening, ultimately realizing the detection of defects (cracks) on the outer edge of the bottle opening.

[0015] The beneficial effects of this utility model are as follows: This utility model is a bottle outer perimeter defect image detection mechanism. The bottle can be placed on a turntable and driven by a drive motor to rotate around a vertical axis. The image information acquisition of the bottle can be carried out on the turntable, making the bottle more stable during the image information acquisition process. Since the image information acquisition is carried out during the rotation of the bottle, the image acquisition device can completely acquire the image information of the entire outer ring of the bottle, ensuring the accuracy of the bottle defect detection.

[0025] Example

[0026] This embodiment provides a bottle body peripheral defect image detection mechanism, see [link / reference] Figure 1 The system includes a horizontally arranged fixed plate 1, on the upper side of which is a support device 3 and an image acquisition device 4. The support device 3 can complete the support and positioning of the bottle, and the image acquisition device 4 can complete the acquisition of the overall image information of the bottle, thus completing the defect detection of the bottle. The structure of the image detection mechanism (the above-mentioned bottle body peripheral defect image detection mechanism) is described in detail below with reference to the accompanying drawings.

[0027] In this embodiment, as the core technical concept of this utility model, the supporting device 3 includes a supporting unit, which includes a turntable rotatably mounted on the upper side of the fixed plate 1 and capable of supporting the wine bottle. The lower side of the turntable is connected to a drive motor capable of driving its rotation. The wine bottle can be placed on the turntable and, under the action of the drive motor, drives the wine bottle to rotate around the vertical axis. The image acquisition device 4 is configured to periodically complete the acquisition of several images of the wine bottle during the rotation of the wine bottle. That is, when the wine bottle rotates one revolution, the image acquisition device 4 can complete the acquisition of several images at a preset frequency. Based on this, the image acquisition of the wine bottle is carried out on the turntable, which makes the wine bottle more stable during the image acquisition work. Furthermore, because the image acquisition work is carried out during the rotation of the wine bottle, the image acquisition device 4 can completely acquire the image information of the entire outer ring of the wine bottle, ensuring the accuracy of the wine bottle defect detection work.

[0028] To ensure the stability of the wine bottle when the turntable rotates, and thus to ensure the accuracy and clarity of image acquisition, as a preferred embodiment, the turntable is also provided with grippers on opposite sides, and the wine bottle can be stably fixed on the turntable by the grippers.

[0029] As a further preferred embodiment, to further ensure the gripper's fixing effect on the wine bottle, the two grippers are arc-shaped structures with opposite openings.

[0030] In this embodiment, multiple sets of support units are arranged linearly. The image acquisition device 4 includes multiple sets of image acquisition units corresponding to the multiple sets of support units. The support device 3 is also provided with a transfer device (not shown) on one side, which can transfer the bottle from the first support unit to the next support unit in a step-by-step manner. The transfer device can be a transfer gripper or other robotic arm structure, and no additional restrictions are made here. Based on this structure, the multiple sets of image acquisition units can complete the acquisition of image information at different positions of the bottle. That is, after the image acquisition unit corresponding to the first support unit completes the image acquisition work, the transfer device can transfer the bottle to the next support unit and continue to complete the acquisition of image information at different positions of the bottle through the image acquisition unit. The step-by-step transfer method, combined with the setting of multiple sets of support units and image acquisition units, ensures that the defect detection work of the bottle can be carried out sequentially and efficiently.

[0031] Specifically, the image acquisition device 4 includes a first support unit 31, a second support unit 32, and a third support unit 33 arranged linearly. The transfer device is configured to transfer the bottle from the input line to the first support unit 31 at the beginning. After the image acquisition unit corresponding to the first support unit 31 completes image acquisition, the transfer device can transfer the bottle from the first support unit 31 to the second support unit 32, and perform image acquisition through the image acquisition unit corresponding to the second support unit 32. Thus, after the bottle completes image acquisition on the third support unit 33 through the image acquisition unit corresponding to the third support unit 33, the transfer device can transport the bottle to the bottle's output line, ultimately completing the bottle defect detection work.

[0032] Furthermore, the image acquisition device 4 includes a first image acquisition unit 41 corresponding to the first support unit 31. A frame is also provided on the upper side of the fixing plate 1. The first image acquisition unit 41 includes a first planar light source 411 located on the frame above the first support unit 31 and illuminating downwards in the opposite direction. The planar light source can provide supplementary lighting to the bottle from top to bottom. A first camera 412 is also provided on the outer side of the first planar light source 411, tilted downwards and capable of acquiring image information of the bottle mouth and bottle shoulder. The first camera 412 is used to acquire images of the bottle mouth and bottle shoulder. When the bottle rotates once, the first camera 412 can acquire 8-12 images, ultimately realizing the detection of defects (cracks and / or gaps) at the bottle mouth and bottle shoulder.

[0033] Furthermore, the image acquisition device 4 also includes a second image acquisition unit 42 corresponding to the second support unit 32. The second image acquisition unit 42 includes a point light source 421 on a frame above the second support unit 32, which is directed downwards and configured to shoot light into the interior of the bottle, thereby making the entire bottle glow. The second image acquisition unit 42 also includes a horizontally arranged second camera 422 and a first reflector 423 located at the head of the second camera 422. Through the cooperation of the second camera 422 and the first reflector 423, the image information of the outer wall of the bottle can be acquired. When the bottle rotates once, the second camera 422 can acquire 8-12 images. With the work of the point light source 421, the defect detection of the entire outer wall of the bottle can be achieved.

[0034] In a preferred embodiment, the second image acquisition unit 42 further includes a third camera 424 capable of acquiring bottleneck image information. When the bottle rotates once, the third camera 424 can acquire 8-12 images. Through the third camera 424 and the work of the point light source 421, the overall defect detection of the bottle bottleneck position can be achieved.

[0035] Furthermore, the image acquisition device 4 also includes a third image acquisition unit 43 corresponding to one of the support units. The third image acquisition unit 43 includes a second planar light source 431 located outside the support unit and fixed to the frame. It is configured to illuminate the upper outer part of the bottle horizontally. In addition, the third image acquisition unit 43 also includes a fourth camera 432 tilted above the second planar light source 431 and capable of acquiring image information of the bottle mouth. The fourth camera 432 can acquire image information of the bottle mouth. When the bottle rotates once, the fourth camera 432 can acquire 8-12 images, and finally complete the detection of defects (burst and / or riser) at the bottle mouth.

[0036] In a preferred embodiment, the third image acquisition unit 43 further includes a fifth camera 433 horizontally positioned on one side of the second planar light source 431, and a second reflector 434 positioned at the head of the fifth camera 433. Through the cooperation of the fifth camera 433 and the second reflector, the image information of the outer edge of the bottle mouth can be acquired. When the bottle rotates once, the fifth camera 433 can acquire 8-12 images, ultimately realizing the detection of defects (cracks) on the entire outer edge of the bottle mouth.
