All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the application is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] The following combination Figures 1-8 The present invention is described in detail.

[0023] Example A wine bottle appearance mark detection system includes a first conveyor line 1 and a second conveyor line 7. A bottom visual detection device 2 for detecting the bottom of the wine bottle 100 and a six-axis robot 3 for taking the wine bottle 100 from the first conveyor line 1 and placing it on the second conveyor line 7 are arranged between the first conveyor line 1 and the second conveyor line 7. The second conveyor line 7 is provided with a factory logo detection component 4 and a label detection component 6; the six-axis robot 3 includes a six-axis motion mechanism 301, and the end of the six-axis motion mechanism 301 is connected to a two-way telescopic cylinder 302, and the telescopic end of the two-way telescopic cylinder 302 is connected to a splint 303.

[0024] The six-axis motion mechanism 301 is an existing technology. The six-axis manipulator 3 drives the splint 303 to move relative to each other through the bidirectional telescopic cylinder 302 to clamp or release the wine bottle 100; a protective pad 304 is provided on the inner side of the splint 303, and the provided protective pad 304 can protect the surface of the wine bottle 100 and prevent it from being scratched by the splint 303.

[0025] The bottom visual inspection device 2 includes a bracket 201, an inspection camera 205, and a light source device 202. The inspection camera 205 is mounted below the bracket 201 via a camera mounting bracket, and the light source device 202 is mounted above the bracket 201 via a light source mounting bracket 203. The light source device 202 provides a bright environment for the inspection camera 205 to capture images. The inspection camera 205 can detect specific structural features on the bottom of the wine bottle 100 and use these features as a reference to mark the angular position of the wine bottle. Based on this angular information, the six-axis robot 3 can rotate the wine bottle 100 to a certain angle, placing the wine bottle 100 at the correct angle on the second conveyor line 7. This allows the factory logo inspection component 4 and the label inspection component 6 to align with the corresponding positions on the wine bottle 100 for inspection. The label inspection component 6 can be located on both sides of the second conveyor line 7 to inspect the front and back labels of the wine bottles 100 respectively.

[0026] The first conveyor line 1 and the second conveyor line 7 are chain conveyor lines. The first conveyor line 1 conveys the wine bottle 100 to the vicinity of the six-axis robot 3. The six-axis robot 3 picks up the wine bottle 100 and passes it over the bottom visual inspection device 2 for inspection. After the inspection, the six-axis robot 3 rotates the wine bottle 100 and follows it (the six-axis robot 3 and the second conveyor line 7 are relatively stationary) and places it on the second conveyor line 7. The factory logo detection component 4 and the label detection component 6 then inspect the factory logo and label of the wine bottle 100.

[0027] The factory logo detection assembly 4 includes a first connecting base 401 and a lifting mechanism 8. The lifting mechanism 8 includes a lifting base 805 connected to the first connecting base 401. A first camera 405 and a first light source 406 are mounted on the first connecting base 401. The first light source 406 provides a bright environment for the first camera 405 to capture images. The image of the factory logo captured by the first camera 405 is transmitted to the processing system for recognition, thereby determining whether the factory logo is positioned correctly and intact. Defective wine bottles 100 can be alerted to staff for processing, or a rejection mechanism can be configured to achieve automatic operation. The first camera 405 and the first light source 406 can be adjusted in height via the lifting base 805, facilitating subsequent inspection of wine bottles 100 at different heights.

[0028] A first slide rail 402 is provided on the first connecting base 401, facing the second conveyor line 7. A first sliding base 403 is slidably provided on the first slide rail 402. A first camera 405 and a first light source 406 are mounted on the first sliding base 403. A first screw rod 404, which is arranged along the length of the first slide rail 402, is threadedly connected to the first sliding base 403. The first screw rod 404 is connected to a first motor 407 fixed to the first connecting base 401. The first motor 407 drives the first connecting base 401 to slide on the first slide rail 402 via the first screw rod 404, thereby adjusting the distance between the first camera 405 and the first light source 406 and the wine bottles 100, thereby facilitating clear photography of wine bottles 100 of different sizes.

[0029] A driving gear 408 and a driven gear 411 are rotatably mounted on the lifting base 805. The end face of the driven gear 411 is fixedly connected to the first connecting base 401. The driving gear 408 is connected to a second motor 409 fixed to the lifting base 805. A timing belt 410 is sleeved around the driving gear 408 and the driven gear 411. The output shaft of the second motor 409 rotates, driving the driving gear 408. The driving gear 408, in turn, drives the driven gear 411 and the first connecting base 401 via the timing belt 410, causing the first connecting base 401 to swing up and down, adjusting the orientation of the first camera 405, thereby enabling the capture and inspection of wine bottles 100 of different sizes.

[0030] The label detection assembly 6 includes a second connection base 601 and a lifting mechanism 8. The lifting mechanism 8 includes a lifting base 805 connected to the second connection base 601. The second connection base 601 is provided with a second camera 605 and a second light source 606. The second light source 606 provides a bright environment for the second camera 605 to shoot. The image of the front label or back label captured by the second camera 605 is transmitted to the processing system for identification, thereby determining whether the front label or back label is positioned correctly and intact. Defective wine bottles 100 can be notified to the staff for processing, or a rejection mechanism can be configured to achieve automatic operation. The second camera 605 and the second light source 606 can be adjusted in height via the lifting base 805, facilitating the subsequent inspection of wine bottles 100 at different heights.

[0031] A second slide rail 602 facing the second conveyor line 7 is provided on the second connecting base 601. A second sliding base 603 is slidably provided on the second slide rail 602. A second camera 605 and a second light source 606 are mounted on the second sliding base 603. A second screw rod 604 extending along the length of the second slide rail 602 is threadedly connected to the second sliding base 603. The second screw rod 604 is connected to a third motor 607 fixed to the second connecting base 601. The third motor 607 drives the second connecting base 601 to slide on the second slide rail 602 via the second screw rod 604, thereby adjusting the distance between the second camera 605 and the second light source 606 and the wine bottles 100, thereby facilitating clear photography of wine bottles 100 of different sizes.

[0032] On the second conveyor line 7, a backlight assembly 5 is installed opposite the factory logo detection assembly 4 and the label detection assembly 6. This backlight assembly 5 includes a lifting mechanism 8 and a light source board 501. The lifting mechanism 8 includes a lifting base 805 connected to the light source board 501. The backlight assembly 5, located opposite the factory logo detection assembly 4 and the label detection assembly 6, uses the light source board 501 to illuminate the back of the wine bottles 100, further ensuring a bright shooting environment. The light source board 501 can be adjusted in height via the lifting base 805, facilitating subsequent inspection of wine bottles 100 at different heights.

[0033] The lifting mechanism 8 also includes two connecting plates 801 spaced apart from each other. A column 802 is connected between the two connecting plates 801 and is slidably engaged with a lifting base 805. A fourth motor 807 is fixedly mounted on one of the connecting plates 801. The fourth motor 807 is connected to a third screw rod 806 threadedly connected to the lifting base 805. The fourth motor 807 drives the third screw rod 806 to rotate, allowing the lifting base 805 to move stably up and down along the column 802, thereby adjusting the height of the lifting base 805.

[0034] Two spaced-apart limit plates 808 are fixedly mounted on the upright 802. Anti-collision pads 809 are provided on opposing sides of the limit plates 808. The limit plates 808 restrict the movement of the lift base 805. The anti-collision pads 809 reduce vibrations caused by the lift base 805 striking the limit plates 808 when the lift base 805 reaches its limit position, thus preventing damage to any electrical equipment on the lift base 805 due to vibration.

[0035] A slot-shaped photoelectric switch 803 is provided on the limit plate 808, and a sensor plate 804 is provided on the lifting platform 805 to cooperate with the slot-shaped photoelectric switch 803. When the lifting platform 805 moves to the extreme position, the sensor plate 804 at one end will insert into the slot-shaped photoelectric switch 803, thereby controlling the fourth motor 807 to stop working and prevent the continued movement of the lifting platform 805 from damaging the fourth motor 807. At the same time, the slot-shaped photoelectric switch 803 can also be used to detect the origin. That is, when the lifting platform 805 moves to the extreme position at one end, the slot-shaped photoelectric switch 803 senses the sensor plate 804, and the initial position of the lifting platform 805 is recorded as 0. The lifting platform 805 is then moved from this initial position to the correct position according to the required displacement distance.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
