[0038] Embodiment 2

[0039] Embodiment 2 is a preferred example of Embodiment 1.

[0040] As Figure 1-2 shown, this embodiment includes: an operation module 1, a control module 2, an emergency stop module 3, a winding machine module 4, and a vision detection module 5;

[0041] The industrial camera in the vision detection module 5 is connected to the control module 2 through a dedicated video interface. The PLC device of the control module 2 is connected to the control panel of the operation module 1 and the touch screen 13 through the RS-485 interface and the Ethernet interface. Instructions are input on the touch screen 13 of the operation module 1, and the touch screen 13 transmits the instructions to the PLC device for processing. The vision detection module 5 includes a light source device, an imaging device, and an image acquisition and processing device. The light source device provides stable illumination to ensure that the object to be measured can be clearly imaged. A light source controller is set on the light source device to adjust the brightness and switch of the light source. The imaging device includes an image sensor for capturing images and converting them into digital signals, and the lens is responsible for focusing the image of the object to be measured onto the image sensor. The image acquisition card of the image acquisition and processing device is responsible for preliminarily processing the digital signals output by the imaging device and transmitting them to the processor. Select a suitable vision sensor according to the characteristics of the joint and the detection requirements, connect the camera to the computer using an appropriate cable, fix the imaging device in a suitable position to ensure that it can clearly capture the image of the joint and will not affect the detection accuracy due to vibration or movement, and select a suitable light source to trigger the detection process more quickly on the production line. Then, it is necessary to connect the control module 2 to the vision sensor.

[0042] The emergency stop module 3 includes an emergency stop switch and buttons. These components are directly connected to the input module of the upper control module 2 through cables. This connection ensures that when the emergency stop button is pressed, the signal output by the PLC device can be immediately cut off, thereby stopping the operation of the equipment. The PLC device is connected to the winding machine module 4 through the input and output module, including the servo motor driver, photoelectric sensor, tension sensor, etc. of the winding machine module 4.

[0043] The control module 2 uses a PLC device and an input and output module to receive signals from external device sensors, buttons, etc., and outputs control signals to motors, relays, alarm lights 12, etc. The emergency stop switch is usually connected to the input module of the PLC device through one or more signal lines. When the emergency stop switch is triggered, its contact state changes from closed to open. There is a control panel on the PLC device. Through the buttons and switch components connected to the control panel, users can manually input control instructions to the PLC device for processing, thereby controlling the operation of the winding machine module 4. The alarm light 12 and the display screen 11 on the control panel can display the operating status of the PLC device, fault information, and the working conditions of the winding machine module 4, etc. The control panel also provides a parameter setting function. Users can adjust the control parameters of the PLC device through knobs, buttons, or touch screens to meet different control requirements.

[0044] The winding machine module 4 mainly includes: a motor, a transmission device, a shearing mechanism, a roll-changing mechanism, and a tension control system, etc. The motor is connected to the transmission device through transmission components such as couplings or belts, converting the rotational motion of the motor into the linear or rotational motion required for winding.

The shearing mechanism is usually installed near the winding shaft and is connected to the shearing blade through actuators such as robotic arms, cylinders, or hydraulic cylinders to achieve precise shearing of the material. The roll-changing mechanism includes one or more robotic arms, slide rails, cylinders, etc., which cooperate with the winding shaft and the spare reel to complete the automatic roll-changing operation. The circuit connection of the winding machine module 4 mainly includes a power supply circuit, a control circuit, a drive circuit, and a signal transmission circuit. These circuits are interconnected through components such as cables, connectors, and relays to form a complete electrical device.

[0045] The vision detection module 5 acquires the image data of the coil material through an image acquisition and processing device, transmits the image data to a computer or an image processing unit through a data interface for processing, and when a joint is detected, the alarm lamp 12 will emit an alarm signal to prompt the operator to check.

[0046] The operation module 1 includes input devices such as buttons and switches, and output devices such as indicator lights and display screens. After receiving the alarm signal, the operator will go to the front of the device to confirm. If it is confirmed that there is indeed a joint and a roll change is required, the operator will press the "Full Roll Change" button. After the PLC device receives the input signal from the "Full Roll Change" button, it will immediately execute the preset roll-changing program. This program includes steps such as stopping the winding of the current coil material, triggering the shearing mechanism to shear, unlocking the winding shaft, guiding the new coil material in place, and restarting the winding process.
