Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology for packaging cartons, and in particular to a visual inspection device for printing information on cartons. Background Technology

[0002] Before shipping, the printed information on the cardboard boxes needs to be confirmed after sealing. Key information such as product model, production date, batch number, and expiration date must be quickly identified to ensure accuracy. Currently, the appearance inspection of sealed cardboard boxes is mostly done manually by visual inspection. However, manual inspection is too slow for high-speed production lines. Traditional sampling methods result in low inspection coverage, making it difficult to achieve full inspection and significantly increasing the risk of missed defects. Furthermore, sampling cannot record defect data in real time, making it difficult to locate problematic batches, especially in multi-process collaborative production where tracing the source of defects is challenging.

[0042] In this embodiment, the width between the first feed conveyor belt baffle 101 and the second feed conveyor belt baffle 103, and the width between the first discharge conveyor belt baffle 301 and the second discharge conveyor belt baffle 302 are adjustable, thereby making it suitable for detecting cartons of different widths.

[0043] In this embodiment, the visual inspection device includes a smart camera 501, a camera mounting plate 502, and a camera support 503. The camera support 503 is fixed to the side beam 102 of the feed belt, the camera mounting plate 502 is fixed to the camera support 503, and the smart camera 501 is disposed on the camera mounting plate 502.

[0044] The intelligent camera 501 has its own light source, so there is no need for an additional light source and controller. The built-in light source has uniform brightness, and the brightness and flicker can be directly adjusted by the camera software.

[0045] The smart cameras 501 on multiple production lines can be connected to a router via network cable, and then to the central control platform. Multiple smart cameras 501 can be remotely controlled through the central control platform. The detection screens of the smart cameras 501 can be viewed remotely.

The comparison detection result can be connected to devices such as a relay through the signal output by the camera, and the relay is connected to the cylinder solenoid valve to control the movement of the cylinder. When the comparison information is consistent, it is a qualified product, and the cylinder does not move. The carton 9 moves to the carton transfer position 902 of the transfer roller line 2 and the blanking belt line 3 and moves to the carton blanking position 903; when the comparison information is inconsistent, it is a defective product, and the cylinder will be controlled to move. The baffle driving cylinder will带动 the baffle 701 to rise, and the carton 9 will be blocked by the baffle 701 when it moves to the transfer roller line 2. The second sensor 603 detects the carton 9, and the material kicking plate cylinder will带动 the material kicking plate 801 to move from the normal position of the material kicking plate to the material kicking position of the material kicking plate, pushing the carton 9 to the carton material kicking position 904 of the material kicking roller line 4. The back can be connected to the defective product blanking area, and the device can automatically remove unqualified products without stopping the machine.

[0052] The beneficial effects of the vision detection device for carton printing information of the present utility model are:

[0053] This utility model solves the problems of low efficiency, poor reliability, inability to remove defective products in real time, and lack of data traceability caused by reliance on manual inspection in the prior art through the above technical solution, improves the speed and efficiency of carton printing information detection, and can be applied to cartons of different sizes.
