Abstract
Description
Technical Field
[0001] This invention relates to the field of laser edge sealing monitoring equipment, and in particular to a system for monitoring the adjustment of laser power of edge sealing strips. Background Technology
[0002] Laser edge banding technology uses a laser beam to heat the edge banding tape, melting it and fusing it with the edge of the board to achieve a seamless edge banding. Specifically, the laser beam emitted by the laser edge banding machine instantly activates a special polymer functional layer on the edge banding tape, allowing it to penetrate the board fibers and form a mechanical "riveting," thus achieving a strong edge banding effect. In the field of edge banding technology, traditional edge banding processes often rely on manual operation and static parameter settings, leading to fluctuations in edge banding quality and low production efficiency. Especially when handling edge banding strips and boards of different materials, thicknesses, or shapes, traditional methods struggle to ensure precision and consistency. Furthermore, the inability to monitor parameters such as temperature, position, and speed in real time during the edge banding process makes it difficult to detect and address anomalies promptly, further impacting product quality and stability.
[0003] To address these issues, the industry has begun exploring the use of advanced sensor technology and intelligent control systems to improve the accuracy and efficiency of the edge sealing process. However, most existing edge sealing monitoring systems suffer from insufficient accuracy, slow response speed, and limited functionality, failing to meet the demands for high-precision, real-time monitoring and intelligent control.

Detailed Implementation
[0035] This invention provides a technical solution; please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 A system for monitoring and adjusting the laser power of edge sealing strips includes a detection device, a feedback detection module, a comparison module, an adjustment module, and a monitoring acquisition and display module. The detection device and the feedback detection module are connected by a line, the output of the feedback detection module is connected to the comparison module, the adjustment module is mounted outside the comparison module, and the output of the adjustment module is connected to the monitoring acquisition and display module by a line.
[0036] The detection device includes an optical system: responsible for receiving the infrared radiation energy emitted by the object being measured. The optical system can receive light from the object and focus this light into the inside of the photodetector through refraction, reflection and other means to form an image of the object. At the same time, by adjusting the parameters and structure of the optical system, precise control and operation of the light can be achieved, thereby obtaining the required optical information.
[0037] Photodetector: It converts the received infrared radiation energy into an electrical signal. When the light from the optical system shines on the surface of the photodetector, the detector absorbs the light energy and converts it into electrical energy, thereby realizing the detection of light and transmitting the signal to the signal amplifier and signal processing circuit.
[0038] Signal amplifier and signal processing circuit: Amplifies the electrical signal output by the photodetector for subsequent processing. The amplified electrical signal is filtered and converted from analog to digital to extract information related to the temperature of the object being measured.
[0039] Display output system: Displays the processed temperature information in digital and graphical form, and displays the data transmitted from the signal amplifier and signal processing circuit through the input interface, making it convenient for staff to view and use.
[0040] The feedback detection module includes sensors responsible for sensing physical quantities such as the position, orientation, temperature, and pressure of an object and converting them into electrical signals. The sensor output signals are amplified, filtered, and denoised to improve signal quality and accuracy. Furthermore, the combination of the sensors and the control system enables automatic temperature regulation, thereby improving the efficiency of laser edge sealing and the quality of the finished product. The sensors measure temperature by receiving infrared radiation energy emitted by the laser equipment, offering advantages such as a wide measurement range, fast response speed, and non-contact measurement.
[0041] Signal conditioning circuit: Responsible for analyzing, converting, and calculating the conditioned signal, converting the analog signal into a digital signal suitable for data acquisition, control processes, calculation, display, or other purposes. The signal conditioning circuit first amplifies the sensor output signal to ensure it matches the input range of the ADC, thereby improving measurement accuracy and sensitivity. Filters in the signal conditioning circuit remove noise, improving the signal-to-noise ratio and ensuring the accuracy of subsequent processing. Transformers, optocouplers, or magnetic couplings are used to transmit the signal from the source to the measurement end, while simultaneously cutting off the grounding loop to block high-voltage surges and common-mode voltage. The linearization circuit in the signal conditioning circuit uses specific algorithms and circuit design to convert nonlinear signals into linear signals for more accurate processing by subsequent circuits. Finally, the analog-to-digital converter in the signal conditioning circuit converts the amplified, filtered, isolated, and linearized analog signal into a digital signal for display by the display module for operator reading.
[0042] Data Processing Unit: Receives physical quantity information from the Data Processing Unit and performs timely feedback control operations according to the preset control strategy. The Data Processing Unit includes a data storage device, which uses a multi-level cache structure to store input data, intermediate data, and output data. The Vector Processing Unit has a certain number of processing units, each of which processes one vector element simultaneously, achieving high-speed data computation for parallel data processing. The Data Flow Controller is responsible for managing data transmission, scheduling, and coordination to ensure data order and correctness. The Data Flow Controller controls the flow of data within the Data Processing Unit. The Instruction Issuance Unit converts input instructions into corresponding operation signals to control the operation of the Data Processing Unit, sends instructions to the corresponding processing units, and adjusts the operating status and frequency of the processing units as needed.
[0043] Feedback control systems reduce the error signal by adjusting the input or control strategy. The data processing unit compares the output signal with the desired value, calculates the error, and then calculates the control input based on the control law, applying it to the system to reduce the error and bring the output closer to the desired value. The feedback control system captures the output signal of the controlled object in real time, compares the measured output signal with the desired reference signal, calculates the deviation between the two (the error signal), and calculates the appropriate control input based on a pre-designed control law (such as a PID controller) to minimize the error. The actuator, according to the controller's instructions, applies corresponding control actions to the controlled object, adjusting its state so that the output signal gradually approaches the desired value. The output signal of the controlled object is again captured by the sensor and transmitted back to the controller, forming a closed-loop feedback. The controller continues to adjust the control input based on the deviation between the new output signal and the desired signal, repeating this cycle until the system reaches a stable state.
[0044] The comparison module includes a signal integration circuit: it amplifies, filters, and linearizes the weak electrical signals output by the sensors, receives signals from multiple signal sources, and combines these signals through internal logic or physical mechanisms, then outputs one or more processed signals. The signal integration circuit first receives signals from different signal sources, which can be analog or digital signals. In analog circuits, signal superposition is usually achieved using adders, adding multiple signals to obtain a new signal. In digital circuits, signal superposition involves logical operations such as AND, OR, and NOT. During signal integration, the circuit needs to transform the signals to meet the requirements of subsequent processing. For example, analog signals need to be amplified, filtered, or level-shifted; digital signals need to be encoded, decoded, or subjected to logical operations. The output section of the signal integration circuit typically includes an output buffer or driver circuit to output the processed signal to subsequent circuits or systems. Output control ensures the stability and accuracy of the signal while meeting the requirements of subsequent circuits for parameters such as signal level and impedance. The structure of the signal integration circuit varies depending on the application requirements.
[0045] Analog-to-digital converters (ADCs) convert analog signals into digital signals for subsequent digital processing and analysis. Sampling involves replacing the original continuous signal with a sequence of signal samples at regular time intervals, effectively discretizing the analog signal in time. The ADC samples the input analog signal through a sampling circuit, acquiring the amplitude of the input signal at regular time intervals. Quantization approximates the original continuously changing amplitude values with a finite number of amplitude values, transforming the continuous amplitude of the analog signal into a finite number of discrete values with certain intervals. The ADC quantizes the sampled signal, dividing the continuous amplitude into several discrete levels. Quantization is typically achieved by comparing the input signal with a reference voltage. The quantized values are then represented in binary numbers and converted into a binary or multi-valued digital signal stream. The ADC converts the quantized discrete amplitudes back into binary codes to obtain the corresponding digital output.
[0046] The microcontroller is responsible for controlling the entire module's workflow. When the power is on, the microcontroller first performs initialization operations, including setting the reset circuit, starting the clock oscillator, and clearing internal registers and memory. The microcontroller's central processing unit (CPU) reads instructions from the program memory and decodes and executes them. Instruction execution involves data reading, calculation, and logical judgment. The data memory is used to store temporary data generated during program execution. The microcontroller communicates and controls the adjustment module and the monitoring, acquisition, and display module through input / output interfaces (I / O).
[0047] Communication interface: This allows the module to exchange data and control with the feedback detection module and the regulation module. The communication interface can be physical or logical, and its implementation can be hardware, software, or a combination of both. Physical interfaces include actual ports on the device, such as USB interfaces, Ethernet interfaces, etc., used for connecting and transmitting electrical signals.
[0048] The adjustment module includes an input terminal: it processes the signal generated by the comparison module. Processing unit: Responsible for processing input signals and generating output signals according to preset algorithms or logic. The processing unit reads instructions from memory through the CPU, decodes them and executes corresponding operations, such as arithmetic operations, logical operations, and data transmission.
[0049] Feedback module: Used to monitor the output signal and adjust the operation of the processing unit to achieve more precise control. By feeding back part or all of the system output to the input, comparing it with the input signal, an error signal is formed. The system is then adjusted according to the error signal to achieve the desired output state. This feedback mechanism improves the stability, accuracy and robustness of the system.
[0050] Output end: Transmits signals to the monitoring acquisition and display module for display and processing; The adjustment module and monitoring, acquisition, and display module include a dynamic adjustment module: This module automatically adjusts the startup power based on a startup marker when the feedback-controlled laser starts. Based on feedback control and optimization algorithms, it monitors the system's operating status or external environmental changes in real time, adjusting system parameters or control signals according to preset goals and rules to achieve dynamic optimization of system performance. Its core idea is to enable the system to adaptively respond to changes in the external environment or internal disturbances, maintaining stability, efficiency, and reliability.
[0051] The monitoring and alarm module is used to issue an alarm when an abnormal temperature is detected. It collects target parameters or status information in real time through sensors. The sensors convert physical quantities into electrical signals for subsequent processing. The collected electrical signals need to undergo signal processing to improve their accuracy and reliability. Signal processing includes amplification, filtering, and conversion steps to ensure that the signal accurately reflects changes in the target parameters or status. The processed signal is compared with a preset alarm threshold. When the signal exceeds or falls below the alarm threshold, the monitoring and alarm module triggers alarm logic and generates an alarm signal.
[0052] The data display module integrates and displays data from the detection device, feedback detection module, comparison module, and adjustment module. It includes a liquid crystal display (LCD) screen composed of liquid crystal molecules and two planes with fine grooves. The liquid crystal molecules are arranged in a specific pattern between the two planes. When light passes through the liquid crystal, it becomes polarized and twists, thus achieving the display function. The control circuit converts externally input data and instructions into the LCD display. Pins are used to connect to external devices and transmit data and instructions. The driver receives data and instructions from the control circuit and converts them into high and low level signals, thereby controlling the arrangement of the liquid crystal molecules to achieve the display. In write mode, the microcontroller (such as a single-chip microcomputer) sends the ASCII codes of the letters, numbers, or symbols to be displayed to the LCD module. These data and instructions are transmitted to the driver through pins. The driver receives them, converts them into high and low level signals, and establishes an electric field on the LCD screen. The electric field changes the arrangement of the liquid crystal molecules, thereby controlling the pixels and ultimately facilitating the observation of detection data. Internally, it also includes control equipment for controlling and driving the entire device.
[0053] The optical system includes lenses and mirrors for focusing and guiding infrared radiation energy.
[0054] The display output system includes a light field converter, an adaptive chopper, an optical divider, a wavefront correction mode stabilizer, and a detector, which are used together to measure the temperature of an object.
[0055] The sensor is a temperature sensor, and there are at least six sets of them, used to output measurement results in analog or digital form.
[0056] The signal conditioning circuit includes an amplifier, a filter, and a comparator.
[0057] The data processing unit consists of a microprocessor, an arithmetic logic unit (ALU), and an embedded system.
[0058] The processing unit includes a microprocessor, an operational amplifier, a comparator, and an analog-to-digital converter.
[0059] The photodetector includes a detection element, a thermistor housing, and a conversion circuit, and the photodetector is mounted on the upper surface of the detection device.
[0060] The data processing unit includes a core processing unit, a data storage unit, a data transmission unit, a data analysis unit, a control unit, and input / output interfaces, which are connected to the display output system via lines.
[0061] The analog-to-digital converter includes an analog input circuit, a sample-and-hold circuit, a quantization circuit, an encoding circuit, and a digital output interface. The digital output interface is connected to the data display module via a connection line.
[0062] The detection device monitors laser power data and outputs the data to the feedback detection module through its internal optical system, photodetector, signal amplifier, signal processing circuit, and display output system. Through the cooperation of internal sensors, signal conditioning circuit, data processing unit, and feedback control system, the obtained data is integrated and adjusted before being output to the comparison module. After comparison by the signal conditioning circuit, analog-to-digital converter, and microcontroller, the data is finally transmitted to the adjustment module via the communication interface. It is then further adjusted through the internal feedback module and finally displayed through the monitoring, acquisition, and display module for easy reading and use by staff. By adding a detection device to monitor the laser power in real time and transmit the monitoring data, the existing monitoring equipment can be avoided from being affected by the ambient temperature and the temperature of the workpiece itself when monitoring the device. This can cause the heating rate required by the device for the workpiece to deviate from the temperature generated by the control equipment, thus affecting the sealing of the workpiece and reducing the yield of the workpiece. By combining the added feedback detection module, comparison module, and adjustment module, the data is integrated and compared, and then uploaded, providing a clear and direct display of the data information. This allows staff to easily operate the device based on the data, thereby significantly improving the overall automation of the device.
