[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figs. 1 to 3 The present embodiment of a vision-based rapid intelligent detection device for the sealing performance of finished cigarettes includes a placement box 1, a placement plate 2 placed inside the placement box 1, a detection gas chamber 16 fixedly connected to the top surface of the placement plate 2, and a cover 3 hinged to the placement box 1.

[0024] A light source 8 is fixedly installed on the top surface of the placement plate 2. A mounting bracket 10 is fixedly connected to the top surface of the placement plate 2. A high-speed camera 11 is fixedly installed on the top surface of the mounting bracket 10. A detection chamber cover 5 is fixedly installed on the top surface of the detection chamber 16. A negative pressure generator 12 is fixedly installed on the top surface of the placement plate 2. A regulating valve 13 is fixedly installed on the top surface of the placement plate 2. A delivery pipe 15 with one end penetrating through the detection chamber cover 5 and extending into the detection chamber 16 is fixedly connected to the top surface of the detection chamber cover 5. A switch valve 14 is fixedly installed on the outer peripheral wall of the delivery pipe 15.

[0025] The delivery pipe 15, regulating valve 13 and negative pressure generator 12 are connected by pipes. The high-speed camera 11 is located on the back of the light source 8. The mounting bracket 10 is a U-shaped bracket. The detection chamber 16 is a transparent cabin structure. The switch valve 14 is located on the top of the detection chamber cover 5.

[0026] Specifically, the finished cigarette pack is placed in the detection chamber 16, the top cover 5 of the detection chamber is closed, and the switch valve 14 is closed. The lamp source 8 and the high-speed camera 11 are turned on. The lamp source 8 is turned on and stays lit for a short time. Observe whether a clear image appears on the display screen 4, and ensure that the nine-square grid test points on the lamp source 8 are completely and clearly imaged on the finished cigarette pack. After the test points are complete and clear, the control board sends a shutdown debugging command, and the high-speed camera 11 and the lamp source 8 are immediately turned off and put into a waiting detection mode. Then, the normal test is started. The control board sends an start detection command, and the control board immediately controls the lamp source 8 to expose and the high-speed camera 11 to take pictures, performing vacuum extraction on the inside of the detection chamber 16. The regulating valve 13 is used to adjust the atmospheric pressure inside the detection chamber. In the first step, the negative pressure generator 12 extracts atmospheric pressure from the detection chamber to create a vacuum environment. The control board then controls the high-speed camera 11 to capture two sets of images: one set of images showing the cigarette pack in a non-vacuum state in the detection chamber 16, and the other set showing the cigarette pack in a vacuum state in the detection chamber 16. The display screen 4 compares the two sets of images to quickly detect the sealing condition of the finished cigarette pack. When the nine-square grid test points on the image show significant displacement, and the test points and cigarette pack show obvious morphological changes, the detection software will report to the user that the cigarette pack film seal is qualified. When the nine-square grid test points on the image do not show significant displacement, and the test points and cigarette pack do not show obvious morphological changes, the detection software will report to the user that the cigarette pack film seal is unqualified.

[0027] It should be noted that the light source 8, high-speed camera 11, negative pressure generator 12, regulating valve 13, and switching valve 14 are all conventional devices known to the public in the prior art, and their specific structures and working principles will not be described in detail in this article.

[0028] Please see Figs. 1 to 3 In this embodiment, the placement box 1 is also equipped with a sealing assembly for sealing the placement box 1. The sealing assembly includes two latches 6. One end of each latch 6 is fixedly installed on the front of the placement box 1, and the other end is fixedly installed on the front of the cover 3. A base plate 18 is placed inside the placement box 1. Four support rods 9 are fixedly connected to the top surface of the base plate 18. All four support rods 9 are fixedly connected to the placement plate 2. A placement rack 17 is fixedly connected to the front of the placement plate 2. A handle 7 is fixedly connected to the front of the placement box 1. A display screen 4 is fixedly installed inside the cover 3.

[0029] The placement box 1 and the cover 3 are both rectangular prisms with hollow interiors and missing one side. The handle 7 is a U-shaped handle located between two latches 6. The placement rack 17 is a U-shaped rack.

[0030] Specifically, the handle 7 allows for easy handling of the storage box 1. When the storage box 1 is placed on the table, the latch 6 is opened, causing the lid 3 to detach from the storage box 1. The storage box 1 is then opened, and the cigarette pack is placed inside the storage rack 17. The image is then displayed on the display screen 4.

[0031] It should be noted that both the latch 6 and the display screen 4 are conventional devices known to the public in the prior art, and their specific structures and working principles will not be described in detail in this article.

[0032] The working principle of the above embodiments is as follows:

[0033] The placement box 1 can be easily held by the handle 7. When the placement box 1 is placed on the table, the lock 6 is opened, which allows the cover 3 to detach from the placement box 1. The placement box 1 is opened and the cigarette pack is placed under the action of the placement rack 17. The finished cigarette pack is placed in the detection chamber 16, the detection chamber cover 5 is closed, the switch valve 14 is closed, and the control board sends an open detection command. The control board then controls the light source 8 to expose and the high-speed camera 11 to take pictures. The inside of the detection chamber 16 is vacuumed. The control board will control the high-speed camera 11 to take two sets of images. One set of images is of the cigarette pack when the detection chamber 16 is not in a vacuum state, and the other set is of the cigarette pack when the detection chamber 16 is in a vacuum state. The display screen 4 compares the two sets of images to quickly detect the sealing condition of the finished cigarette pack.
