Description

Technical Field

[0001] This application relates to the field of laser technology, and in particular to a laser detection device. Background Technology

[0002] The laser is equipped with a communication interface, a heavy-duty interface, and a laser output device (QCS). The heavy-duty interface includes digital signals, analog signals, and status feedback signals required for control, with signal levels including 0 / 24V, 0-10V, 0-5V, and passive contacts. Previously, detecting these signals required auxiliary equipment such as signal generators, adjustable power supplies, multimeters, and oscilloscopes. Furthermore, due to the laser's control logic and the variety of signals, there was a risk of missed or incorrect measurements. The laser is a power output device, outputting through the QCS, and features high energy density. Due to the laser's efficiency issues and high heat generation, water cooling is necessary. Therefore, ensuring the QCS is securely in place and the cooling water is turned on before testing is essential for the safety of testing personnel and the laser.

[0003] In existing laser detection technologies, the laser is controlled by input current and voltage, but the laser's operating status is not detected. At the same time, the prerequisites for safe use of the laser are not detected. Although the device is equipped with a power meter, the power detection results are not used to guide the laser to perform output power correction. Utility Model Content

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

These terms are only used to distinguish information of the same type from one another. For example, first may also be referred to as second without departing from the scope of one or more embodiments of this application, and similarly, second may also be referred to as first.

[0029] This application provides a laser detection device, which will be described in detail in the following embodiments.

[0030] Figure 1 This diagram illustrates a laser detection device according to an embodiment of the present application, specifically including a detection host, a water pump, an electromagnetic flow meter, a power meter, and a QCS fixing device.

[0031] The detection host is connected to the electromagnetic flowmeter, the power meter, and the QCS fixing device, and includes a signal interface for data interaction with the laser under test;

[0032] The water machine, the electromagnetic flow meter, the power meter, and the laser under test are connected in series through a pipeline to form a water circulation path;

[0033] The QCS fixing device fixes the laser output device of the laser under test. The QCS fixing device is equipped with a piezoelectric switch. After the laser output device is fixed, the piezoelectric switch is closed.

[0034] In this process, the laser output device (QCS) of the laser under test is fixed in place, and the laser under test is then tested. The QCS of the laser under test outputs laser power, and the power meter detects the power of the laser. The water purifier drives the cooling water in the water circulation path to cool the laser testing device, and the flow rate of the cooling water is detected by the electromagnetic flow meter. The testing host summarizes all the collected data to obtain the test result of the laser under test.

[0035] Furthermore, the water pump injects cooling water into the laser under test and the power meter through pipelines, and controls the water temperature of the cooling water.

[0036] Furthermore, the electromagnetic flowmeter detects the flow rate data of the cooling water in the pipeline, supports serial communication, and the detection host reads the flow rate data detected by the electromagnetic flowmeter.

[0037] Furthermore, the signal interface includes an analog signal input port, an analog signal output port, a digital signal input port, and a digital signal output port. The detection host controls the start and stop of the main power supply inside the laser under test and the power output of the laser under test through the analog signal output port and the digital signal output port. The feedback signal of the laser under test is detected through the analog signal input port and the digital signal input port.

[0038] Furthermore, the power meter detects the output power data of the laser under test, supports serial communication, and the detection host reads the output power data.

[0039] Furthermore, the QCS fixing device is connected to the power meter via a flange, so that the laser output by the laser output device is aligned with the center of the detection unit on the power meter.

[0040] Furthermore, the detection host detects the piezoelectric output of the piezoelectric switch, and when the piezoelectric output meets the preset start-up conditions, it detects the laser under test.

[0041] Furthermore, the laser detection device also includes a touch screen that displays detection data associated with the laser under test.

[0042] Among them, according to Figure 2 The provided laser testing device flowchart shows that the testing process for the laser under test first involves piezoelectric switch testing and water circulation testing. Piezoelectric switch testing is achieved through a QCS fixing device. If the piezoelectric switch is not triggered, it indicates that the QCS of the laser under test is not placed in the preset position or is not properly positioned. Water circulation testing is achieved through an electromagnetic flowmeter. If the test results show that the cooling water flow rate or temperature does not meet the actual testing requirements, the laser under test cannot be cooled, potentially leading to damage to the laser and other devices during testing. The water pump adjusts the cooling water flow rate and temperature in real time based on the water circulation test results. It should be noted that the water pump also adjusts the cooling water flow rate and temperature in real time after the laser testing begins. Figure 2 As shown, the system performs power meter temperature detection, water circulation detection, and piezoelectric switch detection. If any of these detections fails the abnormal logic judgment, i.e., the power meter temperature detection, water circulation detection, and piezoelectric switch detection are abnormal, the laser will stop outputting, the test will end, the touch screen will display an output, and an alarm will be issued for the relevant abnormal detection results.

[0043] Data from the piezoelectric switch and water circulation tests are transmitted to the testing host. The host determines whether the piezoelectric switch and water circulation tests pass based on the collected data. If either test fails, the laser test is not initiated; instead, the results are displayed on the touchscreen. If both tests pass, the laser test is initiated. The laser is powered on, its main power supply is activated, and communication is established through the host's signal interface. The host controls the laser's main power supply and power output via analog and digital signal outputs. It also detects the laser's feedback signal via analog and digital inputs. By inputting and outputting analog and digital signals of varying levels, combined with pre-defined laser testing logic, the automated laser testing process is completed.

[0044] In addition, the main testing unit detects the piezoelectric switch on the QCS fixed device via a digital signal input port, detects the temperature of the power meter via an NTC, and reads data from the electromagnetic flow meter and power meter via an RS485 interface. Figure 2 As shown, the laser status feedback signal is detected sequentially. If the laser status feedback signal is abnormal, a warning is issued via the touchscreen. If no abnormality is detected, the target power is compared with the power meter data after the power meter data is read. If the comparison result does not meet expectations, the power control command is adjusted. If the comparison result meets expectations, the laser data is read via the communication command. If the read data is abnormal, the test ends and a warning is issued via the touchscreen. If no abnormality is detected, the read data is displayed via the touchscreen.

[0045] The process of comparing the target power with the power meter data is as follows: the detection host compares the laser power detected by the power meter with the target power output by the laser, outputs control commands to the laser, adjusts the laser output until the power detected by the power meter is consistent with the target power, and thus achieves the calibration of the laser output power.

[0046] In practical applications, the hardware of the detection host can adopt a 24V power input, which is converted to 5V by power isolation module 1, and then to 3.3V by LDO1 to power the main control chip. The 24V is converted to 5V by power module 1, and the 12V supplies power to the external interface circuits. The core architecture of the detection host is STM32F107ZET6 + LAN8720. Analog signal output is achieved by the voltage signal from the DA pin of the STM32F107ZET6 microcontroller, which is then electrically isolated by operational amplifier 1. The output signal of the operational amplifier is then amplified to 0-10V by operational amplifier 1. For analog signal acquisition, the analog voltage signal is divided by resistors and then electrically isolated by operational amplifier 2. The output signal of the operational amplifier is connected to the AD pin of the STM32F107ZET6 microcontroller for signal acquisition. Digital signal output is achieved by connecting the digital output pin of the STM32F107ZET6 microcontroller to the base of an NPN transistor, and the collector to a relay line. The relay switch contact is connected to 24V at one end, enabling the microcontroller to convert the 0 / 3.3V level to 0 / 24V level with electrical isolation. For digital signal input, the 0 / 24V level signal is divided by a resistor and then connected to the emitter of an optocoupler. The collector resistor of the optocoupler is pulled up to 3.3V and simultaneously connected to the digital input pin of the STM32F107ZET6 microcontroller to complete the 0 / 24V level detection. The input signal is electrically isolated from the microcontroller system. The RS232 interface is connected to the input of communication isolation chip 1 through serial port 1 of the STM32F107ZET6 microcontroller. The output of communication isolation chip 1 is connected to RS232 conversion chip 1 to achieve electrical isolation between the external RS232 communication signal and the microcontroller system. The NTC temperature detection uses a 5V resistor connected in series with a 10K resistor and then connected to an NCT thermistor to convert the resistance signal into a voltage signal. This voltage signal is impedance isolated by transport amplifier 2 and then connected to the AD pin of the STM32F107ZET6 microcontroller for signal acquisition. In addition, the touchscreen uses a 24V power supply and RS232 interface for communication. The STM32F107ZET6 microcontroller's serial port 3 is connected to the input of communication isolation chip 3, and the output of communication isolation chip 3 is connected to RS232 conversion chip 2, enabling communication between the touchscreen's RS232 communication signal and the microcontroller while maintaining electrical isolation within the system. The testing host is the core of the entire testing device, containing built-in automated laser testing logic. External interface resources include: network interface, RS232, RS485, 0-10V analog signal output, analog signal AD acquisition, 0 / 24V digital signal output, 0 / 24V digital signal detection, one NTC temperature detection channel, and a touchscreen display. The testing host establishes communication with the laser through the network port and RS232 interface, sending commands to verify the functionality of the laser's network port and RS232 interface.
