Description

Technical Field

[0001] This utility model relates to the field of marking machine monitoring technology, and in particular to a marking machine control system based on the Internet of Things. Background Technology

[0002] Filling is part of industrial production; factories need to fill materials for products such as paints and pigments. In the filling production line, a marking machine is used to affix production labels to the filled products, thus completing the shipment process.

[0003] A search revealed that Chinese utility model patent CN202120576228.0 discloses a filling production line, including a rotary machine mounted on the filling production line. The rotary machine is equipped with a rotating device and a pressing device connected to each other. The rotating device drives the pressing device to rotate, and the pressing device presses the product to drive the product to rotate. An identification module is also mounted on the filling production line, corresponding to the rotary machine, and is used to identify positional information on the product. A marking machine is also mounted on the filling production line, corresponding to the rotary machine, and is used to label the product. A conveyor belt is used to transport the product, and the equipment on the filling production line is connected via the conveyor belt. This utility model's filling production line achieves automatic rotary marking with precise positioning, automatically labeling products, improving industrial production efficiency, facilitating large-scale production, and reducing production costs.

[0004] For example, Chinese utility model patent CN208020990U discloses a marking machine with an embedded control system, including an embedded controller system, a laser emitter, a laser marking head, an emergency stop protection circuit, and a safety interlock circuit. The laser emitter, laser marking head, emergency stop protection circuit, and safety interlock circuit are electrically connected to the embedded controller system. The embedded controller system transmits data bidirectionally to both the laser generator and the laser marking head. The embedded controller system receives signals transmitted by the emergency stop protection circuit and the safety interlock circuit, and sends control commands to the laser generator and the laser marking head. This utility model is highly efficient, safe, stable, easy to control, and has good functional expandability.

[0005] While the existing marking machines can meet basic usage requirements, traditional marking machines on filling production lines cannot collect real-time vibration signals from the marking head and label image data. They also cannot automatically trigger alarms when marking is interrupted or when there is abnormal jamming, which can easily lead to incorrect labels and reduce marking efficiency. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an Internet of Things (IoT)-based marking machine control system to address the above-mentioned deficiencies of the prior art. This system integrates a vibration monitoring module, an industrial camera vision unit, and a data preprocessing unit to detect the operating status of the marking head. When the marking is interrupted or there is an abnormal pause, the system outputs a control signal to control the automatic alarm unit to automatically trigger an alarm. At the same time, the system uploads the corresponding data to the cloud IoT platform, thereby improving the marking efficiency of the marking machine and reducing the character error rate.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0009] Preferably, the industrial camera vision unit acquires image signals of the production label and sends them to the data preprocessing unit for image signal recognition to obtain image information of the production label, and then uploads the image information to the cloud IoT platform through the 5G communication module.

[0010] Preferably, the vibration monitoring module collects the vibration signal of the marking head and sends it to the data preprocessing unit for vibration signal identification to obtain the amplitude information of the marking head, thereby determining the operating status of the marking head, and uploading the operating status to the cloud IoT platform through the 5G communication module.

[0011] Preferably, the data preprocessing unit includes a microcontroller chip U1, a programming port P1, and a crystal oscillator X1, both of which are connected to the microcontroller chip U1.

[0012] Preferably, the vibration monitoring module includes a vibration sensor and a vibration sensor interface J1 electrically connected to the vibration sensor, and the industrial camera vision unit includes an industrial CCD camera and a camera interface J2 electrically connected to the industrial CCD camera. Both the vibration sensor interface J1 and the camera interface J2 are connected to the microcontroller chip U1.

[0013] Preferably, the 5G communication module includes a 5G communication chip U2 and an antenna ANT1 connected to the 5G communication chip U2, and the automatic alarm unit includes a signal output chip U3 and a buzzer LS1 and a light-emitting diode LED1 connected to the signal output chip U3. Both the 5G communication chip U2 and the signal output chip U3 are connected to the microcontroller chip U1.

[0014] By adopting the above technical solution, the IoT-based marking machine control system provided by this utility model has the following beneficial effects: The data preprocessing unit in the marking machine control system is electrically connected to the vibration monitoring module, the industrial camera vision unit, the 5G communication module, and the automatic alarm unit. In actual application, the vibration monitoring module is installed on the marking head of the marking machine, the industrial camera vision unit is installed on the frame of the marking machine, and the 5G communication module establishes a wireless communication connection with the cloud IoT platform. By integrating the vibration monitoring module, the industrial camera vision unit, and the data preprocessing unit, the operating status of the marking head is detected, and a control signal is output to control the automatic alarm unit to automatically trigger an alarm when there is a break in the marking or abnormal lag. This promptly reminds maintenance personnel to replace the marking head, avoiding the generation of more erroneous labels. At the same time, the corresponding data is uploaded to the cloud IoT platform, improving the marking efficiency of the marking machine, resulting in high marking efficiency.

[0021] like Figure 1-2 As shown, the IoT-based marking machine control system includes a vibration monitoring module 1, an industrial camera vision unit 2, a data preprocessing unit 3, a 5G communication module 4, and an automatic alarm unit 5. The data preprocessing unit 3 is electrically connected to the vibration monitoring module 1, the industrial camera vision unit 2, the 5G communication module 4, and the automatic alarm unit 5. In practical applications, the vibration monitoring module 1 is installed on the marking head of the marking machine, the industrial camera vision unit is installed on the frame of the marking machine, and the 5G communication module 4 establishes a wireless communication connection with the cloud-based IoT platform 6. It is understood that the cloud-based IoT platform 6 can be a general-purpose cloud server, etc. The specific installation positions of the vibration monitoring module 1 and the industrial camera vision unit can be set according to the on-site construction requirements, as long as they can collect the corresponding signals.

[0022] Specifically, the industrial camera vision unit 2 acquires image signals of the production labels and sends them to the data preprocessing unit 3 for image signal recognition to obtain image information of the production labels. The image information is then uploaded to the cloud IoT platform 5 via the 5G communication module 4. At the same time, it determines whether the production labels have a phenomenon of interrupted labeling. The vibration monitoring module 1 acquires vibration signals of the marking head and sends them to the data preprocessing unit 3 for vibration signal recognition to obtain amplitude information of the marking head. This determines the operating status of the marking head, i.e., whether there is an abnormal jamming phenomenon. The operating status is then uploaded to the cloud IoT platform 5 via the 5G communication module 4.

[0023] Specifically, the data preprocessing unit 3 includes a microcontroller chip U1, a programming port P1, and a crystal oscillator X1, both of which are connected to the microcontroller chip U1.

Understandably, the vibration sensor can be a general-purpose vibration sensor, used to detect the amplitude signal of the marking head. Later, the main control unit 3 can determine whether there is any abnormal jamming based on the magnitude of the vibration amplitude. The industrial CCD camera can be a CCD camera, used to acquire image signals of the production labels. Later, the main control unit 3 can determine whether there is a breakpoint in the labeling process based on the image signals. The microcontroller main control chip U1 can be an STM32F103V8T6 chip, etc., and the 5G communication chip U2 can be an Exynos980 chip, etc. The signal output chip U3 can be an LM20124MH / NOPB chip, etc., used to power the buzzer B1 or the light-emitting diode LED1 respectively. The buzzer B1 is used to emit a beeping sound for alarm, and the light-emitting diode LED1 is used to emit a flashing light for alarm, prompting maintenance personnel to replace the marking head.

[0024] Understandably, this utility model is reasonably designed and uniquely constructed. It detects the operating status of the marking head by integrating a vibration monitoring module 1, an industrial camera vision unit 2, and a data preprocessing unit 3. When the marking is interrupted or there is an abnormal jam, it outputs a control signal to control the automatic alarm unit 6 to automatically trigger an alarm, promptly reminding maintenance personnel to replace the marking head to avoid generating more erroneous labels. At the same time, it uploads the corresponding data to the cloud IoT platform 6 to improve the marking efficiency of the marking machine, resulting in a high marking efficiency.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
