Description

Technical Field

[0001] This utility model relates to the field of image detection technology for wine bottle defects, specifically a novel bottle bottom defect detection system. Background Technology

[0002] In the defect detection of wine bottles, the inspection of the bottle bottom is often the most difficult. Existing inspection methods usually involve using a transport device to suspend the bottle during transport. A camera with a corresponding light source is placed below the bottle's transport path to collect images of the bottle bottom. The images are then used to determine if there are any defects at the bottle bottom, thus completing the defect detection. However, this method can only detect external defects at the bottle bottom. When there are foreign objects inside the bottle at the bottom, the camera below the transport path alone cannot detect them, resulting in inaccurate defect detection results for the bottle bottom. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a novel bottle bottom defect detection system.

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

[0005] A novel bottle bottom defect detection system includes a horizontally mounted mounting plate with a bottle transport line on its upper side. The transport line is designed to suspend the bottles horizontally. As the core technical concept of this invention, the transport path also includes a defect detection mechanism and a foreign object detection mechanism. Specifically, the defect detection mechanism includes a ring-shaped second light source located below the bottle transport path, with a first defect detection camera below the second light source capable of photographing the bottle bottom. The foreign object detection mechanism includes a third light source located below the bottle transport path, with a foreign object detection camera above the transport path corresponding to the third light source capable of photographing the bottle bottom. Based on this structure, the first defect detection camera and the second light source work together to acquire image information of the bottle's external bottom, while the foreign object detection camera and the third light source work together to acquire image information of the bottle's internal bottom. Finally, the acquired image information enables defect detection on both the inner and outer sides of the bottle bottom, effectively ensuring the accuracy of the bottle bottom defect detection work.

[0006] As described above, a novel bottle bottom defect detection system, in a preferred embodiment, further includes a first light source positioned above the bottle transport path, and a second defect detection camera positioned below the bottle transport path corresponding to the first light source, capable of taking pictures of the bottle bottom. Based on this structure, the cooperation between the first light source and the second defect detection camera enables backlit photography of the outer side of the bottle bottom, while the cooperation between the second light source and the first defect detection camera enables frontlit photography of the outer side of the bottle bottom, thereby achieving different recognition effects and ultimately ensuring that the defect detection work at the bottom of the bottle can be carried out more thoroughly.

[0007] As a further preferred embodiment, to achieve an integrated design of the defect detection mechanism and avoid it occupying a large deployment space, the defect detection mechanism also includes a semi-transparent and semi-reflective mirror tilted below the second light source. Two defect detection cameras are respectively set on both sides of the semi-transparent and semi-reflective mirror. Based on this, one defect detection camera, in conjunction with the light transmittance of the semi-transparent and semi-reflective mirror, can realize the image acquisition work of the bottom of the wine bottle, and the other defect detection camera, in conjunction with the light reflectance of the semi-transparent and semi-reflective mirror, can also realize the image acquisition work of the bottom of the wine bottle. This allows the two defect detection cameras to be deployed in one place based on the semi-transparent and semi-reflective mirror, effectively reducing the space required for the deployment of the two defect detection cameras.

[0008] Preferably, to facilitate easier cooperation between the defect detection camera and the semi-transparent mirror, the tilt angle of the semi-transparent mirror is 45°. Based on this, the first defect detection camera is vertically positioned on the lower side of the semi-transparent mirror with its shooting direction upward, so that the first defect detection camera can capture the image of the bottom of the bottle through the semi-transparent mirror. The second defect detection camera is horizontally positioned on the outer side of the semi-transparent mirror with its shooting direction facing the upper side of the semi-transparent mirror, so that the second defect detection camera, in conjunction with the reflectivity of the semi-transparent mirror, can capture the image of the bottom of the bottle.

[0009] As described above, in order to prevent dust from falling from the bottle and affecting the shooting effect of the defect detection camera when the bottle passes through the defect detection mechanism, a protective plate of transparent material is horizontally provided on the upper side of the second light source.

[0010] To ensure the clarity of images captured by the first defect detection camera and the foreign object detection camera, the vertical height of both cameras is adjustable.

[0011] To further ensure the accuracy of the foreign object defect detection results at the bottom of the bottle, at least two foreign object detection cameras are arranged in parallel.

[0012] The beneficial effects of this utility model are as follows: This utility model is a novel bottle bottom defect detection system. By combining a first defect detection camera and a second light source, it can complete the acquisition of image information of the outer bottom of the bottle. By combining a foreign object detection camera and a third light source, it can complete the acquisition of image information of the inner bottom of the bottle. Finally, the acquired image information can realize the detection of defects on the inner and outer sides of the bottom of the bottle, effectively ensuring the accuracy of the bottle bottom defect detection work.

[0022] Example

[0023] This embodiment provides a novel bottle bottom defect detection system, see [link / reference] Figure 1The system includes a horizontally mounted mounting plate 1, on the upper side of which is a bottle transport line (not shown in the figure). The bottle transport line is designed to perform horizontal suspended transport of the bottle. For example, it can use two clamping belts to perform the suspended horizontal transport of the bottle, or it can use mechanical grippers to achieve the suspended horizontal transport of the bottle. The specific structure of the transport line is not limited here. As the core technical concept of this utility model, a defect detection mechanism 3 and a foreign object detection mechanism 4 are also provided on the transport path of the bottle. The defect detection mechanism 3 can perform defect detection on the bottom of the bottle, and the foreign object detection mechanism 4 can perform foreign object detection on the bottom of the bottle. The structure of the detection system (the above-mentioned novel bottle bottom defect detection system) will be described in detail below with reference to the accompanying drawings.

[0024] In this embodiment, combined with Figure 2 and Figure 3 The defect detection mechanism 3 includes a ring-shaped second light source 33 located below the bottle transport path. A defect detection component 35 is provided on the lower side of the second light source 33. The defect detection component 35 includes a first defect detection camera 356, which can take pictures of the bottle bottom to obtain image information of the bottle bottom. Finally, the defect detection of the bottle bottom is achieved by using the obtained image information.

[0025] In a preferred embodiment, the defect detection mechanism 3 further includes a first light source 31 disposed above the bottle transport path, and the defect detection component 35 further includes a second defect detection camera 358 disposed below the bottle transport path and corresponding to the first light source 31. The second defect detection camera 358 can take pictures of the bottle bottom. Based on this structure, the cooperation between the first light source 31 and the second defect detection camera 358 can realize backlighting of the outer side of the bottle bottom, and the cooperation between the second light source 33 and the first defect detection camera 356 can realize front lighting of the outer side of the bottle bottom, thereby achieving different recognition effects and ultimately ensuring that the defect detection work of the bottle bottom can be carried out more thoroughly.

[0026] Regarding the arrangement of the first light source 31 and the second light source 33, the upper side of the mounting plate 1 is also provided with a frame 2. The first light source 31 is mounted on the frame 2 and the irradiation direction is set towards the downward wine bottle transport path. The upper side of the mounting plate 1 is also provided with a first bracket 32 ​​located below the wine bottle transport path. The second light source 33 is located inside the first bracket 32. The mounting plate 1 has an opening corresponding to the position of the second light source 33. The first defect detection camera 356 and the second defect detection camera 358 are both located below the opening.

[0027] To ensure the clarity of the images captured by the first defect detection camera 356 and the second defect detection camera 358, the vertical height of both the first defect detection camera 356 and the second defect detection camera 358 is adjustable.

[0028] Specifically, regarding the mounting structure of the first defect detection camera 356 and the second defect detection camera 358, the defect detection assembly 35 further includes a first vertical rod 351 vertically disposed on the lower side of the mounting plate 1 and fixed at its upper end to the mounting plate 1, on which a second mounting bracket 355 is provided for adjustable height. The first defect detection camera 356 is located below the opening and fixed on the second mounting bracket 355. The defect detection assembly 35 also includes a second vertical rod 352 vertically disposed on the lower side of the mounting plate 1 and fixed at its upper end to the mounting plate 1, on which a first mounting bracket 353 is provided for adjustable height. The second defect detection camera 358 is located below the opening and fixed on the first mounting bracket 353.

[0029] As a further preferred embodiment, to achieve an integrated design of the defect detection mechanism 3 and avoid it occupying a large deployment space, the defect detection mechanism 3 also includes a semi-transparent and semi-reflective mirror 354 tilted below the second light source 33. Two defect detection cameras are respectively located on both sides of the semi-transparent and semi-reflective mirror 354. Based on this, one defect detection camera, in conjunction with the light transmittance of the semi-transparent and semi-reflective mirror 354, can realize the image acquisition work of the bottom of the wine bottle, and the other defect detection camera, in conjunction with the light reflectance of the semi-transparent and semi-reflective mirror 354, can also realize the image acquisition work of the bottom of the wine bottle. This allows the two defect detection cameras to be deployed in one place based on the semi-transparent and semi-reflective mirror 354, effectively reducing the space required for the deployment of the two defect detection cameras.

[0030] Specifically, combining Figure 4 To facilitate easier integration of the defect detection camera with the semi-transparent mirror 354, a third mounting bracket 357 is provided on the first vertical rod 351 for adjustable height. The semi-transparent mirror 354 is tilted below the opening and fixed to the third mounting bracket 357. The tilt angle of the semi-transparent mirror 354 is preferably 45°. Based on this, the first defect detection camera 356 is vertically positioned below the semi-transparent mirror 354 with its shooting direction upward, so that the first defect detection camera 356 can capture the image of the bottom of the bottle through the semi-transparent mirror 354. The second defect detection camera 358 is horizontally positioned outside the semi-transparent mirror 354 with its shooting direction facing the upper side of the semi-transparent mirror 354, so that the second defect detection camera 358, in conjunction with the reflectivity of the semi-transparent mirror 354, can capture the image of the bottom of the bottle.

[0031] Furthermore, to prevent dust from falling from the wine bottle when it passes through the defect detection mechanism 3 and affecting the shooting effect of the defect detection camera, a transparent protective plate 34 is horizontally provided on the first bracket 32 ​​at the position corresponding to the upper side of the second light source 33.

[0032] In this embodiment, the foreign object detection mechanism 4 includes a third light source 44 located below the bottle transport path, and a foreign object detection component 42 located above the bottle transport path corresponding to the third light source 44. The foreign object detection component 42 includes a foreign object detection camera 422, which is configured to take pictures of the bottom inside the bottle. Based on this structure, through the cooperation of the first defect detection camera 356 and the second light source 33, and the cooperation of the second defect detection camera 358 and the first light source 31, image information of the bottom outside the bottle can be collected. Through the cooperation of the foreign object detection camera 422 and the third light source 44, image information of the bottom inside the bottle can be collected. Finally, the collected image information can realize the defect detection of the inside and outside of the bottom of the bottle, effectively ensuring the accuracy of the defect detection work at the bottom of the bottle.

[0033] Regarding the arrangement of the third light source 44, a second bracket 43 is provided on the upper side of the mounting plate 1 below the wine bottle transport path, and the third light source 44 is horizontally arranged on the upper side of the second bracket 43.

[0034] Regarding the arrangement of the foreign object detection camera 422, in order to ensure the clarity of the image captured by the foreign object detection camera 422, the vertical height of the foreign object detection camera 422 is adjustable. Specifically, the foreign object detection mechanism 4 also includes a support rod 41 vertically arranged on one side of the second bracket 43, and the foreign object detection assembly 42 also includes a fourth mounting bracket 421 that is adjustable in height and is arranged on the support rod 41. The foreign object detection camera 422 is located above the third light source 44 and fixed on the fourth mounting bracket 421.

[0035] As a preferred embodiment, in order to further ensure the accuracy of the foreign object defect detection results at the bottom of the bottle, at least two foreign object detection cameras 422 are arranged in parallel.
