Description

[0048] The following is a detailed description of the implementation of the present disclosure in conjunction with specific accompanying drawings:

[0049] Figure 1 is a structural schematic diagram of a carbon fiber bundle width measuring device provided by an embodiment of the present disclosure. Refer to Figure 1 , the carbon fiber bundle width measuring device includes:

[0050] a main unit 10 and a probe 11;

[0051] The main unit 10 includes a main control module 101, a light source driving module 102, an input / output module 103, and a power supply module 104;

[0052] The probe 11 includes a light source module 110 and a sensor module 111;

[0053] The main control module 101 is respectively connected to the light source driving module 102, the input / output module 103, the power supply module 104, and the light source module 110; the light source driving module 102 is connected to the light source module 110;

[0054] The light source driving module 102 is configured to drive the light source module 110 to operate. The light source module 110 is configured to emit an optical intensity signal towards the carbon fiber bundle sample to be detected. The input / output module 103 is configured to receive external input commands and send the information calculated by the main control module 101 to an external terminal;

[0055] The power supply module 104 is configured to supply power to the main control module 101, the light source driving module 102, the input / output module 103, the light source module 110, and the sensor module 111. The sensor module 111 is configured to collect the optical intensity signal transmitted through the carbon fiber bundle by the light source module 110.

[0056] In this embodiment, the power supply module 104 is used to supply power to each module of the entire measuring device, including the main control module 101, the light source driving module 102, the input / output module 103, and the sensor module 111, to ensure that each module can operate stably. The input / output module 103 includes an input unit and an output unit. The input unit is used to receive external input commands, such as commands to start measurement, set parameters, etc. The output unit can send the data sent by the main control module 101 and relevant information such as the working status of other modules to an external terminal device, such as a computer, a smart phone, etc., for the user to view and analyze.

[0057] The light source driving module 102 is connected to the main control module 101. The light source driving module 102 can drive the light source module 110 to operate according to the instructions received from the main control module 101. For example, the light source driving module 102 provides appropriate current and voltage for the light source module 110 to ensure that the light source module 110 can stably emit an optical intensity signal with a specific intensity and wavelength.

[0058] Under the drive of the light source driving module 102, the light source module 110 continuously emits an optical intensity signal towards the carbon fiber bundle sample to be detected, so that the sensor module 111 can collect the optical intensity signal transmitted through the carbon fiber bundle. The sensor module 111 can convert the collected optical intensity signal and send it to the main control module 101 for analysis and processing.

[0059] In this embodiment, the working principle of the carbon fiber bundle width measuring device is as follows:

[0060] After the device is started, an initialization stage is carried out. First, the power supply module 104 supplies power to the main control module 101, the light source driving module 102, the input / output module 103, and the sensor module 111 of the entire measuring device, so that each module is in a workable state. Secondly, the input / output module 103 can receive instructions sent by the user or other devices and send the instructions to the main control module 101. These instructions include starting measurement, setting measurement parameters, etc.

[0061] Measurement stage: When the main control module 101 receives the instruction sent by the input / output module 103, it sends a control signal to the light source driving module 102. The light source driving module 102 drives the light source module 110 in the probe 11 to work according to the control signal of the main control module 101. The light source module 110 emits an optical intensity signal to the carbon fiber bundle sample to be detected under the drive of the light source driving module 102. When the optical intensity signal passes through the carbon fiber bundle to be measured, due to the presence of the carbon fiber bundle, the optical intensity signal will change, generating a transmitted optical intensity signal related to the width of the carbon fiber bundle. The sensor in the sensor module 111 can capture the transmitted optical intensity signal, preprocess it (signal conversion, filtering, etc.), and send the preprocessed signal to the main control module 101.

[0062] Data processing stage: After the main control module 101 receives the data sent by the sensor module 111, it further analyzes and processes the data according to a preset algorithm. Since different widths of the carbon fiber bundle will result in different transmitted optical intensity signals, the main control module 101 can calculate the width of the carbon fiber bundle according to the specific relationship between the optical intensity signal and the width of the carbon fiber bundle.

[0063] Result output stage: The main control module 101 sends the relevant information such as the calculated width of the carbon fiber bundle to the input / output module 103. The input / output module 103 can display this information on the display screen 1031 or send it to an external terminal, such as a computer, a smart phone, etc., for the user to view the measurement result.

[0064] It can be concluded from the above that in this embodiment, by integrating the high-precision light source module 110 and the sensor module 111, a non-contact and high-precision measurement of the width of the carbon fiber bundle is realized, effectively avoiding the damage and error that may be brought by traditional contact measurement, and improving the accuracy and reliability of the measurement.

[0065] The carbon fiber bundle width measuring device provided in this embodiment is highly automated and easy for users to operate. The user only needs to send an instruction through the input / output module 103 to complete the measurement process and quickly obtain the measurement result, significantly improving the work efficiency and measurement convenience.

[0066] The carbon fiber bundle width measuring device provided in this embodiment has a compact structure and adopts a modular design, which is convenient for maintenance and upgrading. Moreover, the power supply module 104 is energy-efficient and provides stable and reliable power support for the entire device, meeting the development concept of green environmental protection. In an embodiment of the present disclosure, the light source module 110 includes a plurality of LED lights, and the plurality of LED lights are linearly arranged.

[0067] In this embodiment, the light source module 110 includes a plurality of LED lights. All of these LED lights are 0805 package warm white SMDs of the same model (SZYY0805W). The plurality of LED lights are linearly arranged to form a shadowless light source effect, ensuring uniform illumination of the carbon fiber bundle coverage area.

[0068] As can be seen from the above, the linear arrangement of a plurality of 0805 package warm white SMD LEDs ensures the shadowless effect and uniform illumination of the light source module 110, improves the accuracy and reliability of the carbon fiber bundle width measurement, simplifies the light source design, and reduces the cost.

[0069] In an embodiment of the present disclosure, referring to Figure 2 , the input / output module 103 includes:

[0070] a display screen 1031, a button 1032, and a communication unit 1033;

[0071] The display screen 1031 is connected to the main control module 101 and is configured to display the status information and width data of the carbon fiber bundle width measurement;

[0072] The button 1032 is connected to the main control module 101 and is configured to send a measurement instruction to the main control module 101;

[0073] The communication unit 1033 is connected to the main control module 101. The communication unit 1033 is further used to connect to an external terminal and is configured to send the measured width data of the carbon fiber bundle to the external terminal.

[0074] In this embodiment, the input / output module 103 includes a display screen 1031, a button 1032, and a communication unit 1033, which are mainly used for human-computer interaction and input and output of control signals.

[0075] The display screen 1031 is a device that can visually display relevant information on the measurement of the carbon fiber bundle width. The display screen 1031 is connected to the main control module 101 and can display the status information during the measurement process, such as whether the measurement is in progress, whether the communication connection is normal, whether there are any abnormalities, and the final width data, etc. The display screen 1031 plays an important role in information feedback throughout the measurement process. It enables users to monitor the progress and results of the measurement in real time, facilitating timely responses from users when problems occur. For example, if the measurement shows an abnormality, the user can check whether there are problems with the sample or the device. At the same time, for application scenarios that require recording width data, users can directly read accurate data from the display screen 1031 for recording. The button 1032 is connected to the main control module 101. As an input device, its main function is to send measurement instructions to the main control module 101. Users can trigger the measurement action by pressing the button 1032. In this embodiment, there are 7 function menu buttons 1032, which are fixed below the display screen 1031. Among them, the measurement button is installed in the middle of the main body housing, and the transmission button is installed in the lower middle part of the main body housing. For example, if the user presses the transmission button, the measurement result of this time will be sent to the cloud platform.

[0076] The communication unit 1033 is respectively connected to the main control module 101 and an external terminal. Its core function is to send the measured width data of the carbon fiber bundle to the external terminal. This connection method enables the measurement device to be not only an independent measurement tool but also capable of data interaction with other devices. The communication unit 1033 can be WiFi, 4G communication, 5G communication, Bluetooth communication, etc.

[0077] It can be concluded from the above that in the design of the input / output module 103 in this embodiment, the measurement status and data are visually displayed through the display screen 1031, the operation instruction input is simplified by the button 1032, and the seamless connection with the external terminal is achieved by the communication unit 1033, which can significantly improve the user interaction experience and data transmission efficiency, and enhance the practicality and flexibility of the carbon fiber bundle width measurement device.

[0078] In an embodiment of the present disclosure, referring to Figure 2 , the main body 10 further includes a power management module 105;

[0079] The power management module 105 includes a charge-discharge circuit, a linear voltage regulator circuit, a battery level detection circuit, and a power switch;

[0080] The charge-discharge circuit is connected to the linear voltage regulator circuit, the linear voltage regulator circuit is connected to the battery level detection circuit, and the charge-discharge circuit is connected to the power switch; the power switch is also respectively connected to the power module 104 and the main control module 101.

[0081] In this embodiment, when an external power supply (such as a charger) is connected to the device, the charge and discharge circuit is responsible for safely and efficiently transmitting the electrical energy of the external power supply to the battery for charging. When the device is operating, the battery supplies power to the device through the charge and discharge circuit. The linear voltage regulator circuit can receive the original voltage from the charge and discharge circuit or the external power supply and convert it into a stable voltage required by various components of the device, which helps to protect sensitive components from voltage fluctuations and ensure the stable performance of the device. The power detection circuit monitors the remaining power of the battery in real time and feeds this information back to the main control module 101. This helps the device accurately display the remaining power, remind the user to charge when the power is low, or automatically turn off non-essential functions to save power when the power is extremely low.

[0082] The power switch is the key to controlling the on / off of the entire power management module 105. It receives instructions from the main control module 101 or other control signals to control the turning on and off of the power supply. In addition, the power switch can also be integrated with functions such as overcurrent protection and short-circuit protection to ensure that the device is not damaged under abnormal conditions.

[0083] In summary, the power management module 105 can be used for the stable supply of voltage and current, charging protection, power detection, and power on / off. It can reduce unnecessary energy losses and improve the overall energy efficiency ratio of the device through fine power management and optimization.

[0084] In an embodiment of the present disclosure, referring to Figures 3 to 8 , the host 10 further includes a host housing;

[0085] The host housing is designed as an integrated structure, and the probe 11 is integrally connected to the host housing.

[0086] The probe 11 further includes:

[0087] A probe housing, a light slot, a lens, a lens fixing seat, a sensor fixing seat, and a light source fixing seat;

[0088] The probe 11 is fixed to the upper part of the host housing, the light source module 110 is fixed to the light source fixing seat, and the sensor module 111 is arranged at the center of the sensor fixing seat.

[0089] The lens is fixed to the probe housing by plugging, and the centers and edges of the center of the light slot, the center of the lens fixing seat, the center of the sensor fixing seat coincide with each other.

[0090] In this embodiment, the probe 11 is fixed to the upper part of the mainframe housing and is composed of a probe housing, a sensor fixing base, a light slot, a lens, a base of the probe 11, a light source fixing base, and a lens fixing base. The lens is fixed to the probe housing by plugging. The linear array LED light source board in the light source module 110 is fixed to the upper part of the probe 11 with screws. The sensor module 111 is installed at the center of the sensor fixing base, that is, the lower part of the probe 11; the center of the light slot coincides with the center, the center and the edge of the lens fixing base and the sensor fixing base. According to the size characteristics of the carbon fiber bundle, the probe 11 adopts a miniaturized structure to optimize the optical path transmission efficiency.

[0091] In an embodiment of the present disclosure, the sensor module 111 includes:

[0092] A photoelectric sensor;

[0093] The photoelectric sensor is connected to the main control module 101.

[0094] In this embodiment, the sensor module 111 includes a photoelectric sensor for collecting the light intensity signal transmitted by the carbon fiber bundle to be measured after being emitted by the light source module 110. When the light source module 110 emits a light intensity signal to the carbon fiber bundle, the light passes through the carbon fiber bundle. Due to the presence of the carbon fiber bundle, the light intensity will change. The photoelectric sensor can sense this change in light intensity and convert it into an electrical signal. For example, for a photoelectric sensor of the photodiode type, when light irradiates its PN junction, the photon energy is absorbed, thereby generating photo-generated carriers, forming a current signal in the external circuit, and the magnitude of this current signal has a certain relationship with the received light intensity.

[0095] The photoelectric sensor is connected to the main control module 101 and can transmit the converted electrical signal (this electrical signal reflects the light intensity information after transmission by the carbon fiber bundle) to the main control module 101. The main control module 101 can process these electrical signals according to a pre-set algorithm. Since different widths of the carbon fiber bundle will result in different transmitted light intensity signals, the main control module 101 can calculate the width of the carbon fiber bundle according to the specific relationship between the light intensity signal and the width of the carbon fiber bundle (this relationship may be obtained through prior calibration or theoretical derivation).

[0096] The specific relationship can be a linear relationship. For example, when the width of the carbon fiber bundle increases, the area through which the light passes decreases. According to the Lambert-Beer law (applicable under certain conditions), the attenuation of the light intensity is linearly related to the thickness of the medium through which the light passes (which can be analogized to the width of the carbon fiber bundle here). In the case where the carbon fiber bundle has a uniform material, a fixed light wavelength, and a stable measurement environment, this linear relationship can be used for relatively accurate width measurement.

[0097] The specific relationship can also be a piecewise function relationship. When the width of the carbon fiber bundle is small, the attenuation of the light intensity may be mainly affected by the material itself and the surface properties of the carbon fiber; while when the width is large, the attenuation of the light intensity may be more affected by the geometric propagation limit of the light. Therefore, there may be a piecewise function relationship. The specific specific relationship needs to be set according to the actual situation.

[0098] As can be seen from the above, the optoelectronic sensor has high sensitivity to changes in light intensity. In the measurement of the width of the carbon fiber bundle, even a slight change in the width of the carbon fiber bundle will cause a slight change in the transmitted light intensity. The optoelectronic sensor can accurately sense this slight change in light intensity and convert it into a corresponding electrical signal. This enables the present embodiment to achieve high-precision measurement of the width of the carbon fiber bundle and improves the accuracy of the measurement.

[0099] In an embodiment of the present disclosure, the main control module 101 includes:

[0100] A microcontroller and a peripheral circuit.

[0101] In this embodiment, the microcontroller has functions such as data calculation, logical judgment, program storage and execution, module coordination, and external communication. The peripheral circuit may include a clock circuit, a reset circuit, etc. The clock circuit provides a stable clock signal for the microcontroller. The reset circuit is used to restore the microcontroller to its initial state. When the measuring device is started or an abnormal situation occurs (such as program runaway, power fluctuation, etc.), the reset circuit can make the microcontroller start working again to ensure the stability of the system.

[0102] In an embodiment of the present disclosure, the working principle of a carbon fiber bundle width measuring instrument is as follows:

[0103] After the carbon fiber bundle width measuring device is started, the display screen 1031 presents a welcome interface, and then WiFi connection is performed. During this period, the display screen 1031 shows the WiFi connection status. Once the WiFi connection is successful, the display screen 1031 will display the connection success. Then, the user sequentially selects the keys 1032 for the yarn spreading device station number, the yarn spreading round number, and the yarn spreading channel number. After the three pieces of information are confirmed to be correct, the display screen 1031 shows the state to be measured. When the user presses the measurement button, the device will start to measure the width, including collecting light intensity information. The sensor module 111 transmits the collected data to the main control module 101, and the main control module 101 processes and calculates according to the received data to obtain the width of the carbon fiber bundle and displays it on the display screen 1031. If the user presses on the transmission key 1032, the measurement result of this time will be sent to the cloud platform. During the measurement process, if no key 1032 is pressed within 20 seconds at any stage, the device automatically enters the standby state, clears the screen, and after the measurement key 1032 is pressed, the width measuring device restarts.

[0104] It can be concluded from the above that the present embodiment provides a carbon fiber bundle width measuring device based on the optoelectronic principle. By using a linearly arranged LED circuit board as the light source and a structural layout where the sensor and the light source are placed parallel and aligned, a rectangular detection probe 11 dedicated to carbon fiber bundles is designed, reducing costs and power consumption and broadening the usage scenarios; through the comprehensive prediction model, the width determination of the carbon fiber bundle and real-time data transmission are achieved.
