Description

TECHNICAL FIELD

[0001] The steel plate production equipment particularly relates to a steel plate label missing intelligent detection alarm system and a detection method. BACKGROUND

[0002] With the improvement of production intelligence, steel enterprises begin to generally use robots in the production field. Among them, the use of automatic labeling robots is particularly widespread in the labeling process of steel plates, steel coils and sampling plates. However, due to reasons such as label adhesion, unstable clamping of the robot hand, insufficient viscosity of the adhesive backing, label missing and label falling occur frequently, which requires manual inspection and re-sticking, greatly affecting production efficiency.

[0003] Patent document CN206020282U discloses a label missing detection and removal device, which can be used to detect label missing. The device detects label missing in the high-speed labeling process of a circular bottle through a fiber optic sensor and a color sensor. The fiber optic sensor is used to detect whether the bottle opening is in place, and the color sensor is used to detect the label position. When the signal strength of the two meets the requirements, it indicates that the bottle is properly labeled, otherwise an alarm signal is sent and the bottle is removed. Patent document CN106864903A discloses an automatic labeling machine with a label missing alarm device, which can be used to detect label missing. The device detects whether the label is present through a photoelectric sensor or an infrared reflection sensor, and the detection result is sent to the alarm device and the controller. Once no label is detected, an alarm is sent and the labeling machine stops working. SUMMARY

[0004] The purpose of the present application is to provide a steel plate label missing intelligent detection alarm system and a detection method.

[0005] The technical solution adopted by the present application to solve the technical problem is:

[0006] A steel plate label missing intelligent detection alarm system, comprising:

[0007] An image acquisition component corresponding to the position of the labeling machine, which can acquire image data of the steel plate and its label in the labeling machine;

[0008] An image transmission component in communication with the image acquisition component through a signal line. The image acquisition component provides the acquired image data to the image transmission component, and the image transmission component transmits the image data.

[0009] An image processing component in communication with the image transmission component through a signal line. The image transmission component transmits the image data to the image processing component, and the image processing component processes the image data.

[0010] An audio alarm component, which is in signal communication with the image processing component and controlled by the image processing component to send an audio alarm signal.

[0011] An auxiliary lighting component, which corresponds to the position of the labeling machine and the image acquisition component, and provides auxiliary lighting for the steel plate and its label in the process of image acquisition by the image acquisition component.

[0012] Specifically, the image acquisition component includes:

[0013] An image camera, which corresponds to the position of the labeling machine and is directed to the steel plate bearing part in the labeling machine, and acquires image data of the steel plate and its label.

[0014] In an embodiment of the present application, the image camera is an AI camera.

[0015] The image transmission component includes:

[0016] A transmission switch, which is in communication with the image camera through a network cable, and receives image data of the steel plate and its label from the image camera and transmits the image data.

[0017] The image processing component includes:

[0018] An image processor, which is in communication with the transmission switch through a network cable, receives image data from the transmission switch, and identifies and processes the image data.

[0019] In an embodiment of the present application, the image processor is an embedded image processing system.

[0020] The audio alarm component includes:

[0021] An alarm buzzer, which is in communication with the image processor through an audio cable, and sends an audio alarm signal controlled by the image processor.

[0022] The auxiliary lighting component includes:

[0023] An illumination fill-in light, which corresponds to the position of the image camera and the labeling machine, and is directed to the steel plate bearing part in the labeling machine, and provides auxiliary lighting for the steel plate and its label, so that the image camera can acquire clear and effective image data.

[0024] A steel plate label missing intelligent detection method, which uses the above intelligent detection alarm system, and includes the following steps:

[0025] S1, the image camera captures the steel plate bearing part of the labeling machine, acquires image data of the steel plate and its label, and transmits the image data to the image processor through the transmission switch;

[0026] S2, the image processor uses an object detection AI model to analyze image data. First, it identifies whether there is a steel plate in the inspected area. After detecting that there is a steel plate, it identifies whether there is a label on the steel plate and classifies it according to the identification results into two categories: with label and missing / fallen label.

[0027] S3, within a predetermined time period, if the image processor fails to detect or recognize a QR code label within the detection area, it controls the alarm buzzer to emit an audio alarm signal.

[0028] In step S3, when the image processor detects abnormal scenarios such as the steel plate being blocked by a robotic arm / person or other objects, or the absence of a steel plate, it sets the target to "no target" and the alarm buzzer does not activate.

[0029] The advantages of this invention are:

[0030] This system uses an AI camera as an image recorder, combined with an object detection AI model, to efficiently and accurately identify the presence of steel plates and their labels. Through analysis of image data, the system can quickly determine whether labels are missing or detached, improving detection efficiency and reducing misjudgments caused by human factors. The system can record the steel plates in the labeling machine in real time and transmit and analyze the image data instantly. Once a missing or detached label is detected, the system can automatically trigger an alarm mechanism without manual intervention, achieving automated detection. In abnormal scenarios such as the steel plate being obstructed by the robotic arm or personnel, or the absence of a steel plate, the system can intelligently judge and avoid false alarms, effectively solving quality problems caused by missing or detached steel plate labels, and improving production efficiency and product quality.
