Description

Technical Field

[0001] The utility model relates to the technical field of impurity detection in wine bottles, and specifically relates to an impurity detection system for wine bottles based on machine vision. Background Technique

[0002] In the process of liquor production, there are many production links and complex processes. Especially in the filling link, reasons such as unclean cleaning of filling bottles, failure of the filtration system, and mechanical impact during capping and packaging can cause impurities such as glass fragments, floccules, and hairs to be mixed into the liquid in the bottle. If this liquor containing impurities flows into the market, it will not only seriously damage the physical health of consumers, but also have a great negative impact on enterprises and society. Therefore, it is necessary to detect impurities in wine bottles.

[0003] However, the industrial camera on the existing impurity detection system for wine bottles can only capture the image of one direction of the wine bottle and cannot capture the multi-angle images of the wine bottle, which is likely to result in the situation that the internal impurities of the wine bottle cannot be detected. At the same time, it is not convenient to quickly fix the wine bottle, affecting the detection efficiency.

[0004] In view of the above problems, it is urgent to innovate and design on the basis of the original impurity detection system for wine bottles. Content of the Utility Model

[0005] The purpose of the utility model is to provide an impurity detection system for wine bottles based on machine vision to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An impurity detection system for wine bottles based on machine vision, including an operation table, the inner wall of the operation table is rotatably installed with a first rotating shaft through a bearing, a disc is fixed on the top of the first rotating shaft, a low-speed motor is fixed on the bottom of the first rotating shaft, and the outer wall of the low-speed motor is fixed to the bottom of the operation table through a mounting plate;

[0007] The inner wall of the disc near the edge of the disc is rotatably installed with a second rotating shaft through a bearing, a tray is fixed on the top of the second rotating shaft, a placement groove is opened on the top of the tray, a fixing mechanism is arranged inside the placement groove, a gear is fixed on the bottom of the second rotating shaft, and a toothed ring is engaged with one side of the gear, and the bottom of the toothed ring is fixed to the top of the operation table.

[0008] Preferably, the fixing mechanism includes a groove, the groove is opened on the inner side of the placement groove, a spring is fixed on the inner wall of the groove, a clamping rod is fixed at the end of the spring, and the end of the clamping rod penetrates through the inside of the groove and is located inside the placement groove.

[0009] Preferably, an industrial camera, a buzzer and an industrial computer are respectively arranged on one side of the top of the operating table, and the industrial computer is electrically connected to both the industrial camera and the buzzer.

[0010] Preferably, the central axes of the first rotating shaft, the disc and the toothed ring coincide with each other, and the second rotating shaft, the support plate, the placing groove and the gear are equally angularly distributed about the central axis of the toothed ring.

[0011] Preferably, the grooves, the springs and the clamping rods are equally angularly distributed about the central axis of the placing groove. One side of the top of the clamping rod is designed to be inclined, and the clamping rod and the groove form a clamping sliding structure.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the impurity detection system in the wine bottle based on machine vision, the bottom of the wine bottle is inserted downward into the interior of the placing groove. The bottom of the wine bottle contacts the inclined surface on one side of the top of the clamping rod, and the wine bottle pushes several clamping rods to move into the interiors of several grooves simultaneously, so that several springs are compressed simultaneously. Under the elastic force of several springs, the ends of several clamping rods complete the fixation of the bottom of the wine bottle, thus facilitating the rapid fixation of the wine bottle. When the wine bottle is lifted upward, the wine bottle can be quickly disassembled, thereby improving the efficiency of impurity detection in the wine bottle;

[0013] By starting the low-speed motor, the low-speed motor can drive several wine bottles to rotate around the central axis of the disc, and several wine bottles can rotate simultaneously. The rotating wine bottles can be captured by the industrial camera at multiple angles, enabling the industrial computer to analyze the images more precisely, and being able to more accurately judge whether there are impurities in the wine bottle, ensuring the quality of the wine.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-7 , the present utility model provides a technical solution: a wine bottle internal impurity detection system based on machine vision, including an operating table 1, the inner wall of the operating table 1 is rotatably installed with a first rotating shaft 2 through a bearing, the top of the first rotating shaft 2 is fixed with a disc 3, the bottom of the first rotating shaft 2 is fixed with a low-speed motor 4, and the outer wall of the low-speed motor 4 is fixed to the bottom of the operating table 1 through a mounting plate;

[0024] The inner wall of the disc 3 near the edge of the disc 3 is rotatably installed with a second rotating shaft 5 through a bearing, the top of the second rotating shaft 5 is fixed with a support plate 6, the top of the support plate 6 is provided with a placement groove 7, a fixing mechanism is arranged inside the placement groove 7, the bottom of the second rotating shaft 5 is fixed with a gear 8, and one side of the gear 8 is engaged with a toothed ring 9, and the bottom of the toothed ring 9 is fixedly connected to the top of the operating table 1.

[0025] The fixing mechanism includes a groove 10, the inner side of the placement groove 7 is provided with a groove 10, the inner wall of the groove 10 is fixed with a spring 11, the end of the spring 11 is fixed with a clamping rod 12, and the end of the clamping rod 12 penetrates through the inside of the groove 10 and is located inside the placement groove 7.

[0026] On one side of the top of the operating table 1, an industrial camera 13, a buzzer 14 and an industrial computer 15 are respectively arranged, and the industrial computer 15 is electrically connected to both the industrial camera 13 and the buzzer 14.

[0027] The central axes of the first rotating shaft 2, the disc 3 and the toothed ring 9 coincide with each other, and the second rotating shaft 5, the support plate 6, the placement groove 7 and the gear 8 are equally angularly distributed about the central axis of the toothed ring 9, ensuring that when the disc 3 rotates, the placement groove 7 can rotate around the central axis of the disc 3, and at the same time, the toothed ring 9 can make the gear 8, the second rotating shaft 5, the support plate 6 and the placement groove 7 rotate self.

[0028] The groove 10, the spring 11 and the clamping rod 12 are all equally angularly distributed about the central axis of the placing groove 7. One side of the top of the clamping rod 12 is inclined. The clamping rod 12 and the groove 10 form a clamping sliding structure, ensuring that when the bottom of the wine bottle contacts the inclined surface on one side of the top of the clamping rod 12, the wine bottle can push the clamping rod 12 to move into the inside of the groove 10, causing the spring 11 to be compressed.

[0029] Working principle: When using the machine vision-based impurity detection system for wine bottles, first insert the bottom of the wine bottle downward into the inside of the placing groove 7. The bottom of the wine bottle contacts the inclined surface on one side of the top of the clamping rod 12. The wine bottle pushes several clamping rods 12 to move into the inside of several grooves 10 at the same time, causing several springs 11 to be compressed at the same time. Under the elastic force of several springs 11, the ends of several clamping rods 12 complete the fixation of the bottom of the wine bottle.

[0030] Then start the low-speed motor 4. At this time, the low-speed motor 4 drives the disc 3 to rotate through the first rotating shaft 2, causing the second rotating shaft 5, the support plate 6, the placing groove 7, the gear 8, the wine bottle and the fixing mechanism to rotate around the central axis of the first rotating shaft 2 at the same time. Since the gear 8 and the toothed ring 9 are meshed, the toothed ring 9 causes the second rotating shaft 5, the support plate 6, the placing groove 7, the gear 8, the wine bottle and the fixing mechanism to rotate self. When the wine bottle rotates through the photographing area of the industrial camera 13 during self-rotation, the industrial camera 13 captures the picture of the wine bottle from multiple angles. Then the industrial camera 13 transmits the data to the industrial computer 15. The industrial computer 15 performs image analysis on multiple pictures of the wine bottle. When it is detected that there are impurities in the wine inside the wine bottle, the industrial computer 15 controls the buzzer 14 to generate a prompt sound. The first worker takes down the wine bottle with impurities in the wine and places it in the unqualified area. When it is detected that there are no impurities in the wine inside the wine bottle, the buzzer 14 does not emit a prompt sound. The second worker takes down the wine bottle without impurities in the wine and places it in the qualified area. The third worker replenishes the wine bottles to be detected at the empty placing groove 7. Since the disc 3 can drive several wine bottles to rotate around the central axis of the disc 3, and several wine bottles can rotate self at the same time, several wine bottles can pass through the industrial camera 13 in sequence, so that several wine bottles can be detected in sequence.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
