Description

[0001] The present invention relates to the technical field of detection equipment, and in particular to a method and equipment for detecting cracks at the mouth of a wine bottle. Background Art

[0002] The crack defects of the mouth of glass wine bottles include shallow cracks and deep cracks. Shallow cracks may expand into deep cracks, which not only affect the aesthetics of the wine bottle, but may also cause the wine bottle to leak or break, and have adverse effects on the sealing and safety of the wine bottle. Therefore, wine bottles need to go through the crack detection process of the wine bottle mouth during the production process.

[0003] Current detection methods are generally based on machine vision and image processing technology. Industrial cameras are used to collect real-time image data of the bottle mouths of wine bottles on the production line. After processing and analyzing the image data, it is determined whether there are cracks in the bottle mouths, and then the cracks in the bottle mouths are detected and identified, so as to eliminate unqualified wine bottles with cracks in the bottle mouths and prevent unqualified wine bottles from entering the market.

[0004] However, when there are thin and soft foreign objects such as hair attached to the outer wall of the bottle mouth, the machine may identify these foreign objects as crack defects, resulting in misjudgment, resulting in limited accuracy in sorting qualified and unqualified wine bottles, which needs to be improved.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

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

[0066] Example 1

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

[0068] Step S1, arrange the wine bottles at intervals and make them pass through the cleaning station and crack detection station one by one;

[0069] Step S2: During the movement of the wine bottle, the outer wall of the bottle mouth is first cleaned at the cleaning station, and then the real-time image data of the bottle mouth is collected by an industrial camera at the crack detection station;

[0070] When collecting real-time image data of the bottle mouth, the industrial camera moves synchronously with the inspected wine bottle;

[0071] Step S3, processing and analyzing the real-time image data to distinguish whether there is a crack defect on the bottle mouth;

[0072] Step S4, removing wine bottles with crack defects at the bottle mouth.

[0073] In the above scheme, before collecting the real-time image data of the bottle mouth, the outer wall of the bottle mouth is cleaned first to remove thin, long and soft foreign objects such as hair to avoid identifying these foreign objects as crack defects and causing misjudgment. In addition, when collecting the real-time image data of the bottle mouth, the industrial camera moves synchronously with the inspected bottle, and the two are relatively still, so the collected real-time image data is more accurate, which is conducive to improving the accuracy of bottle mouth crack defect detection and identification.

[0074] Second, see Figure 1 to Figure 6 The present embodiment provides a wine bottle mouth crack detection device, which applies the above-mentioned wine bottle mouth crack detection method. The wine 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. Wine bottles are arranged at equal intervals on the first conveyor line 1 and can pass through the cleaning station 11, the crack detection station 12 and the rejection station 13 one by one. The transportation direction of the first conveyor line 1 is from left to right.

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

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

[0078] The image acquisition mechanism 3 is arranged above the crack detection station 12, and is used to collect real-time image data of the bottle mouth at 360 degrees. The image acquisition mechanism 3 can move up and down at the crack detection station 12, and move synchronously to the right with the wine bottle located at the crack detection station 12, so that when collecting real-time image data of the bottle mouth, the image acquisition mechanism 3 moves synchronously with the inspected wine bottle.

[0079] The rejection mechanism is arranged near the rejection station 13 ; the rejection mechanism includes, for example, a push plate 41 , which is used to push the wine 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 the real-time image data of the bottle mouth, the cleaning mechanism 2 first cleans the outer wall of the bottle mouth of the wine bottle to remove slender and soft foreign objects such as hair to avoid identifying these foreign objects as crack defects and causing misjudgment. Then, the image acquisition mechanism 3 that can move synchronously with the inspected wine bottle acquires the real-time image data of the bottle mouth, and the real-time image data is processed and analyzed to distinguish whether there is a crack defect in the bottle mouth. When there is a crack defect in the bottle mouth, the corresponding wine bottle is pushed into the second conveyor line 14. Through the above scheme, misjudgment is reduced and the accuracy of detecting and identifying crack defects in the wine bottle mouth is improved.

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

[0082] The support plate 21 has a cavity 211 inside, an air inlet head 212 connected to the cavity 211 at the top, an annular groove 213 on the side wall, and an air vent 214 connected to the cavity 211 at the bottom of the annular groove 213. The support plate 21 can move rightward for a distance synchronously with the wine bottles on the cleaning station 11.

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

[0084] The extension arm 23 is disposed transversely, and one end thereof is connected to the outer side of the hollow ring 22 ; a first channel 231 is defined in the extension arm 23 .

[0085] The suspension arm 24 is vertically arranged, and its upper end is connected to the lower side of the extension arm 23 ; a second passage 241 is defined in the suspension arm 24 .

[0086] The spray head 25 is connected to the suspension arm 24, and the outlet of the spray head 25 faces the axis of the support plate 21. The two spray heads 25 are symmetrically arranged relative to the axis of the support plate 21.

[0087] The air inlet head 212, the cavity 211, the air vent 214, the hollow ring 22, the first channel 231, the second channel 241 and the nozzle 25 are connected in sequence. After the cleaning mechanism 2 is moved to move the nozzle 25 to the mouth of the wine bottle, the cleaning mechanism 2 and the wine bottle are moved to the right synchronously, and the air inlet head 212 is connected 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 sprayed by the two nozzles 25 is used to clean the outer wall of the mouth of the wine bottle 360 ​​degrees.

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

[0089] In order to facilitate the rotation of the hollow ring 22 relative to the support plate 21, a drive pipe 27 is also connected to the suspension arm 24, and the drive pipe 27 is connected to the second channel 241; the drive pipe 27 can rotate with the suspension arm 24, and the air outlet direction of the drive pipe 27 is tangent to the circular trajectory formed by the rotation of the drive pipe 27, so that the reverse thrust of the airflow ejected by the drive pipe 27 is used to drive the hollow ring 22 to rotate relative to the support plate 21.

[0090] It is understandable that by reasonably setting the distance between two adjacent wine bottles, it is possible to avoid the reverse thrust of the airflow ejected by the driving pipe 27 from affecting the adjacent wine bottles.

[0091] The image acquisition mechanism 3 includes a support plate 31, a bracket 32 ​​and an industrial camera 33. The bracket 32 ​​is installed on the lower side of the support plate 31, and the industrial camera 33 is installed on the bracket 32. A plurality of (6) industrial cameras 33 are arranged in a circular array below the support plate 31. The image acquisition mechanism 3 can move up and down at the crack detection station 12, and move synchronously to the right with the wine bottle located at the crack detection station 12. The plurality of industrial cameras 33 cooperate to collect real-time image data of the bottle mouth at 360 degrees.

[0092] In this embodiment, the support plate 21 and the support plate 31 are connected together by a connecting frame 51. The support plate 21 and the support plate 31 move synchronously, and the distance between the two is adapted to the distance between two adjacent wine bottles on the first conveyor line 1. The top of the connecting frame 51 is rotatably connected to a transmission component 52, and the transmission component 52 moves along the Figure 6 The first rectangular moving trajectory 52 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 a right movement is consistent with the time taken for the wine bottle to pass through the crack detection station 12. Specifically, when the wine 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 downward 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 of the wine bottle) and the multiple industrial cameras 33 are in place (the multiple industrial cameras 33 are distributed around the bottle mouth of the wine bottle that has passed the cleaning station 11). Then, the transmission component 52, the cleaning mechanism 2 and the image acquisition mechanism 3 move right as a whole at a speed consistent with the transportation speed of the first conveyor line 1 (the right movement speed of the wine bottle). In this process, the outer wall of the bottle mouth of the wine bottle is cleaned and the bottle mouth of another wine bottle is inspected; after the inspection is completed, the transmission component 52, the cleaning mechanism 2 and the image acquisition mechanism 3 move upward as a whole and then move left to reset, so as to carry out the next cleaning and inspection.

[0093] It can be understood that in the above solution, when the transmission component 52 moves along the first moving track 52, the mobile cleaning mechanism 2 and the image acquisition mechanism 3 need to maintain Figure 6 The angle shown is achieved by the rotational connection between the connecting frame 51 and the transmission component 52, as well as the deadweight of the cleaning mechanism 2 and the image acquisition mechanism 3 or by adding a counterweight thereto.

[0094] It can be understood 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 right 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 during vertical and horizontal movement can be kept consistent, which makes 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 consistent with the speed and distance during the upward and leftward movement, that is, the time required for detection and resetting of the image acquisition mechanism 3 is consistent.

[0096] Example 2

[0097] See also Figure 1 to Figure 7 The difference between this embodiment and embodiment 1 is that, in this embodiment, the transmission component 52 is along Figure 7 The second moving track 52 in the shape of a triangle moves.

[0098] When the transmission component 52 moves along the second moving track 52, it first moves downward, then moves rightward, and then moves to the upper left to reset. The speed of the transmission component 52 in the process of moving downward, moving rightward, and moving to the upper left is the same, but the distance in the process of moving to the upper left is smaller than the distance in the process of moving downward and moving rightward, that is, the time required for the image acquisition mechanism 3 to reset is smaller than the time spent on detection. In this way, the image acquisition mechanism 3 and the cleaning mechanism 2 can be reset faster (the movement of the two is synchronized), so as to improve the detection efficiency.

[0099] Example 3

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

[0101] The connecting rod 61 is used to connect the supporting plate 21 and the supporting 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 supporting 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 supporting plate 31 .

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

[0105] In the above scheme, when the first rotating shaft 62 and the second rotating shaft 63 move along the two triangular guide rails 67, Figure 8 The angles of the middle 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 cope with the situation where the distance between the industrial camera 33 of the image acquisition mechanism 3 and the bottle mouth is small during detection, when the industrial camera 33 moves to the upper left to reset, the side plate 64 first moves upward by a predetermined distance and then moves downward by the same distance. In this way, while ensuring that the image acquisition mechanism 3 is quickly reset, the time for the industrial camera 33 to move upward away from the wine bottle can be further shortened, thereby avoiding collision between the industrial camera 33 and the bottle mouth.

[0107] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
