Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a method and equipment for detecting cracks in the mouth of a wine bottle. Background Technology

[0002] Cracks at the neck of glass wine bottles can be shallow or deep. Shallow cracks may develop into deep cracks, affecting not only the bottle's appearance but also its potential for leakage or breakage, negatively impacting its seal and safety. Therefore, wine bottles must undergo a crack inspection process at the neck during production.

[0003] Current inspection methods are generally based on machine vision and image processing technology. Industrial cameras are used to collect real-time image data of the bottle openings on the production line. After processing and analyzing the image data, it is determined whether there are cracks in the bottle opening. Cracks in the bottle opening are detected and identified so that unqualified bottles with cracks can be rejected and prevented from entering the market.

[0004] However, when fine, soft foreign objects such as hair are attached to the outer wall of the bottle mouth, the machine may identify these foreign objects as cracks or defects, resulting in misjudgment. This limits the accuracy of sorting qualified and unqualified wine bottles and needs improvement. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0065] The embodiments of the present invention will be described in detail below.

[0066] Example 1

[0067] Firstly, this embodiment provides a method for detecting cracks in the mouth of a wine bottle, comprising the following steps:

[0068] Step S1: Arrange the wine bottles at intervals and let them pass through the cleaning station and crack detection station one by one;

[0069] Step S2: During the movement of the wine bottle, first clean the outer wall of the bottle mouth at the cleaning station, and then collect real-time image data of the bottle mouth at the crack detection station using an industrial camera.

[0070] When collecting real-time image data of the bottle opening, the industrial camera moves synchronously with the bottle being inspected.

[0071] Step S3: Process and analyze the real-time image data to distinguish whether there are cracks or defects at the bottle opening;

[0072] Step S4: Remove bottles with cracks or defects at the bottle neck.

[0073] In the above solution, before acquiring real-time image data of the bottle opening, the outer wall of the bottle opening is cleaned to remove fine, soft foreign objects such as hair, preventing these objects from being identified as crack defects and causing misjudgment. Furthermore, during the acquisition of real-time image data of the bottle opening, the industrial camera moves synchronously with the inspected bottle, while both remain relatively stationary. This results in more accurate real-time image data, which helps improve the accuracy of detecting and identifying bottle opening crack defects.

[0074] Secondly, see Figures 1-6 This embodiment provides a bottle mouth crack detection device, which applies the above-mentioned bottle mouth crack detection method. The bottle mouth crack detection device includes a first conveyor line 1, a second conveyor line 14, a cleaning mechanism 2, an image acquisition mechanism 3, and a rejection mechanism.

[0075] The first conveyor line 1 includes a cleaning station 11, a crack detection station 12, and a rejection station 13. Bottles are arranged at equal intervals on the first conveyor line 1 and can pass through the cleaning station 11, crack detection station 12, and rejection station 13 one by one. The transport direction of the first conveyor line 1 is from left to right.

[0076] The second conveyor line 14 is connected to the rejection station 13; the second conveyor line 14 and the first conveyor line 1 have different transport directions.

[0077] The cleaning mechanism 2 is located above the cleaning station 11 and is used to clean the circumferential outer wall of the bottle mouth in 360 degrees. The cleaning mechanism 2 can move up and down the cleaning station 11 and move synchronously to the right along with the bottle located at the cleaning station 11.

[0078] The image acquisition mechanism 3 is positioned above the crack detection station 12 to acquire real-time image data of the bottle opening from 360 degrees. The image acquisition mechanism 3 can move up and down the crack detection station 12 and move synchronously to the right along with the bottle located at the crack detection station 12, so that the image acquisition mechanism 3 moves synchronously with the bottle being inspected when acquiring real-time image data of the bottle opening.

[0079] The rejection mechanism is located near the rejection station 13; the rejection mechanism includes, for example, a pusher plate 41, which is used to push bottles with crack defects at the bottle mouth into the second conveyor line 14.

[0080] In the above scheme, before the image acquisition mechanism 3 acquires real-time image data of the bottle mouth, the cleaning mechanism 2 first cleans the outer wall of the bottle mouth to remove fine, soft foreign objects such as hair, avoiding misidentification of these foreign objects as crack defects. Then, the image acquisition mechanism 3, which can move synchronously with the inspected bottle, acquires real-time image data of the bottle mouth. By processing and analyzing this real-time image data, it can distinguish whether there is a crack defect in the bottle mouth. When a crack defect is found, the corresponding bottle is pushed into the second conveyor line 14. Through this scheme, misjudgments are reduced and the accuracy of detecting and identifying bottle mouth crack defects is improved.

[0081] The cleaning mechanism 2 includes a support plate 21, a hollow ring 22, an extension arm 23, a boom 24, and a nozzle 25.

[0082] The support plate 21 has an internal cavity 211, an air inlet 212 connected to the top and communicating with the cavity 211, and an annular groove 213 on the side wall. The bottom of the annular groove 213 has a vent hole 214 communicating with the cavity 211. The support plate 21 can move to the right a certain distance synchronously with the wine bottle on the cleaning station 11.

[0083] The hollow ring 22 is rotatably fitted into the annular groove 213, and the inner side of the hollow ring 22 has an annular notch 221 that communicates with the vent 214. The hollow ring 22 can rotate relative to the support plate 21.

[0084] The extension arm 23 is arranged laterally, with one end connected to the outer side of the hollow ring 22; the extension arm 23 has a first channel 231 inside.

[0085] The boom 24 is vertically arranged, and its upper end is connected to the lower side of the extension arm 23; the boom 24 has a second channel 241 inside.

[0086] The nozzle 25 is connected to the boom 24, and the outlet of the nozzle 25 faces the axis of the support plate 21. The two nozzles 25 are symmetrically arranged with respect to the axis of the support plate 21.

[0087] The air inlet 212, cavity 211, vent 214, hollow ring 22, first channel 231, second channel 241 and nozzle 25 are connected in sequence. After the moving cleaning mechanism 2 moves the nozzle 25 toward the mouth of the bottle, the cleaning mechanism 2 moves to the right synchronously with the bottle, connecting the air inlet 212 to the external air source, so that the hollow ring 22 drives the extension arm 23, the hanging arm 24 and the nozzle 25 to rotate, and the airflow from the two nozzles 25 cleans the outer wall of the bottle mouth 360 degrees.

[0088] A position sensor is installed on the lower side of the support plate 21 to detect whether the bottle mouth has moved to a designated position, or a detection camera 26 is installed to detect the real-time position of the bottle mouth. When the detection camera 26 captures the bottle mouth on the first conveyor line 1 moving to the vicinity of the left side of the cleaning station 11, the corresponding control center causes the corresponding external power device to drive the support plate 21 to move down. After the two nozzles 25 are in place (the two nozzles 25 are symmetrically distributed on both sides of the bottle mouth), the cleaning mechanism 2 moves synchronously to the right with the corresponding bottle, so that the outer wall of the bottle mouth is cleaned by the two nozzles 25 that can always rotate around the bottle mouth before the bottle enters the crack detection station 12.

[0089] To facilitate the rotation of the hollow ring 22 relative to the support plate 21, a drive pipe 27 is also connected to the boom 24. The drive pipe 27 is connected to the second channel 241. The drive pipe 27 can rotate with the boom 24. The air outlet direction of the drive pipe 27 is tangent to the circular trajectory formed by the rotation of the drive pipe 27. Thus, the reverse thrust of the airflow ejected by the drive pipe 27 drives the hollow ring 22 to rotate relative to the support plate 21.

[0090] It is understandable that by setting the appropriate spacing between two adjacent bottles, the reverse thrust of the airflow ejected from the drive tube 27 can be prevented from affecting the adjacent bottles.

[0091] The image acquisition mechanism 3 includes a support plate 31, a bracket 32, and industrial cameras 33. The bracket 32 ​​is mounted on the lower side of the support plate 31, and the industrial cameras 33 are mounted on the bracket 32. A circular array of multiple (6) industrial cameras 33 is located below the support plate 31. The image acquisition mechanism 3 can move up and down at the crack detection station 12, and can also move synchronously to the right along with the wine bottle located at the crack detection station 12. The multiple industrial cameras 33 work together to acquire real-time image data of the bottle opening from 360 degrees.

[0092] In this embodiment, the support plate 21 and the support plate 31 are connected together by a connecting frame 51. The movement of the support plate 21 and the support plate 31 is synchronous, and the distance between them is adapted to the distance between two adjacent wine bottles on the first conveyor line 1. A transmission component 52 is rotatably connected to the top of the connecting frame 51. The transmission component 52 moves along... Figure 6 The first moving trajectory 52, which is rectangular in shape, moves to realize the longitudinal and lateral movement of the cleaning mechanism 2 and the image acquisition mechanism 3; when the transmission component 52 moves along the first moving trajectory 52, the time taken to complete one rightward movement is the same as the time taken for the wine bottle to pass through the crack detection station 12. Specifically, when the bottle moves to the vicinity of the left side of the cleaning station 11, the transmission component 52, the cleaning mechanism 2, and the image acquisition mechanism 3 move downwards as a whole, so that the two nozzles 25 are in place (the two nozzles 25 are symmetrically distributed on both sides of the bottle mouth) and the multiple industrial cameras 33 are in place (the multiple industrial cameras 33 are distributed around the bottle mouth of the bottle that has passed the cleaning station 11). Then, the transmission component 52, the cleaning mechanism 2, and the image acquisition mechanism 3 move to the right at the same speed as the transport speed of the first conveyor line 1 (the rightward movement speed of the bottle). During this process, the cleaning of the outer wall of the bottle mouth and the inspection of the bottle mouth of another bottle are completed. After the inspection is completed, the transmission component 52, the cleaning mechanism 2, and the image acquisition mechanism 3 move upwards and then to the left to reset, so as to carry out the next cleaning and inspection.

[0093] It is understandable that in the above scheme, when the transmission component 52 moves along the first moving trajectory 52, the moving cleaning mechanism 2 and the image acquisition mechanism 3 need to maintain [a certain distance / condition]. Figure 6 The angle shown is achieved through the rotational connection between the connecting frame 51 and the transmission component 52, as well as the weight of the cleaning mechanism 2 and the image acquisition mechanism 3, or by adding counterweights on this basis.

[0094] It is understandable that in the above scheme, when the transmission component 52 moves along the first moving trajectory 52, the vertical displacement of the transmission component 52 can be determined according to the rightward movement speed of the wine bottle and the width of the crack detection station 12. In this way, the speed of the transmission component 52 can be kept consistent during vertical and horizontal movement, making it easier to control the movement of the transmission component 52.

[0095] In the above scheme, when the transmission component 52 moves along the first moving trajectory 52, the speed and distance of the transmission component 52 during the downward and rightward movement are the same as the speed and distance during the upward and leftward movement. That is, the time required for the image acquisition mechanism 3 to detect and reset is the same.

[0096] Example 2

[0097] See Figures 1-7 The difference between this embodiment and Embodiment 1 is that, in this embodiment, the transmission component 52 moves along... Figure 7 The second moving trajectory 52, which forms a triangle, moves.

[0098] When the transmission component 52 moves along the second moving trajectory 52, it first moves downwards, then to the right, and then moves to the upper left to reset. The speed of the transmission component 52 is the same during the downward, rightward, and upper left movements, but the distance traveled during the upper left movement is less than the distance traveled during the downward and rightward movements. That is, the time required for the image acquisition mechanism 3 to reset is less than the time spent on detection. In this way, both the image acquisition mechanism 3 and the cleaning mechanism 2 can reset more quickly (their movements are synchronized), thereby improving detection efficiency.

[0099] Example 3

[0100] See Figures 1-8 The difference between this embodiment and embodiment 2 is that, in this embodiment, the bottle mouth crack detection device further includes a connecting rod 61, a first rotating shaft 62, a second rotating shaft 63, and a side plate 64.

[0101] Link 61 is used to connect support plate 21 and support plate 31.

[0102] A first connecting sleeve 65 is rotatably connected to the first rotating shaft 62, and the first connecting sleeve 65 is connected to the left side of the support plate 21.

[0103] A second connecting sleeve 66 is rotatably connected to the second rotating shaft 63, and the second connecting sleeve 66 is connected to the right side of the support plate 31.

[0104] A side plate 64 is disposed above the first conveyor line 1, and the side plate 64 has two triangular guide rails 67; a first rotating shaft 62 and a second rotating shaft 63 are slidably and rotatably connected to a guide rail 67 respectively; the guide rails 67 are arranged with reference to the aforementioned second moving trajectory 52. ​​The moving speed of the first rotating shaft 62 and the second rotating shaft 63 along the guide rails 67 remains stable.

[0105] In the above scheme, when the first rotating shaft 62 and the second rotating shaft 63 move along two triangular guide tracks 67, Figure 8 The angles of the central support plate 21 and the support plate 31 will never change, which is more conducive to ensuring the smooth completion of cleaning and testing.

[0106] Furthermore, in order to address the situation where the distance between the industrial camera 33 of the image acquisition mechanism 3 and the bottle opening is small during detection, when the industrial camera 33 moves to the upper left to reset, the side plate 64 first moves upward a predetermined distance, and then moves downward by the same distance. In this way, while ensuring that the image acquisition mechanism 3 resets quickly, the time for the industrial camera 33 to detach from the bottle is further shortened, thereby avoiding collision between the industrial camera 33 and the bottle opening.

[0107] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
