[0002] Automatic fabric layup machines are essential automated equipment in the modern textile and composite materials industry, widely used in the lamination process of fiber-reinforced composite materials (such as carbon fiber and glass fiber). Their main function is to automatically lay fabric (usually continuous fabric or prepreg) onto the mold surface, achieving a highly efficient and precise fabric laying process. Automatic fabric layup machines not only significantly improve production efficiency but also, to a certain extent, ensure the uniformity and consistency of the layup quality, making them one of the key pieces of equipment for achieving high-precision composite material molding. However, despite their significant role in improving production efficiency and reducing labor costs, existing fabric layup machines still face some technical challenges, particularly in the accuracy of fabric positioning. Due to the characteristics of fabrics, such as elasticity and stretchability, existing fabric layup machines struggle to accurately determine the fabric's position during the laying process, especially as misalignment and overlap can easily occur during fabric movement.

[0043] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

Any embodiment or design scheme described as "optionally" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "optionally" or "for example" is intended to present the relevant concepts in a specific manner.

[0046] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0047] During the fabric laying process, the edge alignment accuracy is a very important evaluation indicator for the fabric laying effect. Currently, the edge alignment motor uses two diffuse reflection photoelectric sensors to calculate the position. There are only two states: occluded and unoccluded. The position accuracy depends only on the installation accuracy, which is not conducive to high-precision control of the edge alignment effect.

[0048] At least to address the above-mentioned problems, embodiments of this application provide a method for aligning the edges of a fabric laying machine. The method includes: sending Manchester-coded pulse waves to a sensor array and receiving multiple level signals fed back by the sensor array; obtaining pulse information based on the level signals, the pulse information including pulse length, number, and the position of the corresponding sensor; and analyzing and processing the pulse information to obtain the position and tilt angle of the fabric.

[0049] In this embodiment, Manchester-coded pulse waves are sent to each sensor in the sensor array, and the level signals fed back by each sensor are received. The level signals are analyzed to obtain pulse information, including the position of the corresponding sensor, and then the position and tilt angle of the fabric are obtained using the pulse information. This fabric laying machine edge alignment method can support multi-channel sensor signal transmission and reception, improving response speed and efficiency. It automatically obtains the precise position and tilt angle of the fabric using the received pulse information, facilitating real-time control of the fabric laying machine during the laying process.

[0050] Figure 1A This diagram illustrates an application scenario of the fabric laying machine edge alignment method described in this application. The fabric laying machine edge alignment device 1 can be used to implement the fabric laying machine edge alignment method provided in this application embodiment, but the application scenarios of the fabric laying machine edge alignment method provided in this application embodiment are not limited to... Figure 1A The fabric spreading machine's edge-aligning device 1 is shown. (As shown in the image) Figure 1A As shown, the fabric laying machine edge alignment device 1 includes a fabric laying machine 11, a local processor 12, and a display terminal 13. The fabric laying machine edge alignment method provided in this embodiment can be applied to the local processor 12.

[0051] in, Figure 1A The local processor 12 can be a single local processor, a cluster of multiple local processors, or a cloud computing center, etc., and is not specifically limited here. Although Figure 1A Only one fabric spreading machine 11, one local processor 12, and one display terminal 13 are shown in the image, but it should be understood that... Figure 1A The examples in this paper are only for understanding this solution. The specific number of local processors 12 and display terminals 13 should be flexibly determined based on the actual situation.

[0052] In some other implementations, the fabric laying machine edge alignment device 1 may not include the display terminal 13, but only a local processor 12 with display function and the fabric laying machine 11. The fabric laying machine edge alignment method provided in this application embodiment can be applied to the local processor 12. The local processor 12 with display function may include tablet computers, PDAs, mobile phones, personal computers, and voice interaction devices, or monitoring devices, etc., and is not limited here.

Figure 1B This diagram illustrates the structure of the endpoint-cloud interaction scenario in these implementation methods. For example... Figure 1B As shown, the terminal-cloud interaction system 2 includes a terminal 20 and a cloud server 21. The terminal 20 and the cloud server 21 can communicate with each other, and the communication method is not limited to wired or wireless.

[0054] The terminal 20 can be mobile or fixed. For example, it can be a wireless terminal or a wired terminal. A wireless terminal can refer to a device with wireless transceiver capabilities, which can be deployed indoors, outdoors, and in industrial workshops. The terminal 20 can be a mobile phone, tablet computer, laptop computer, etc., and is not limited thereto. The cloud server 21 can include one or more servers, or one or more processing nodes, or one or more virtual machines running on the server. The cloud server 21 can also be referred to as a server cluster, management platform, data processing center, etc., and is not limited thereto in this embodiment.

[0055] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0056] The following embodiments of this application provide a method for aligning edges using a fabric laying machine, which, for example, can be achieved through... Figure 1A The local processor 12 shown Figure 1B The cloud server 21 shown is used to implement this. Figure 2 The diagram shown is a flowchart illustrating the edge-aligning method of the fabric laying machine described in an embodiment of this application. Figure 2 As shown, the fabric spreading machine edge alignment method includes steps S11 to S13.

[0057] Step S11: Send Manchester-coded pulse waves to the sensor array and receive multiple level signals fed back from the sensor array. Manchester coding enables the receiver to receive data through over-synchronization, avoiding prolonged static levels and improving signal anti-interference capabilities.

[0058] Step S12: Obtain pulse information based on the level signal. The pulse information includes pulse length, number, and the position of the corresponding sensor.

[0059] Step S13: Analyze and process the pulse information to obtain the position and tilt angle of the cloth.

[0060] In some possible implementations, a microcontroller unit (MCU) serves as an integrated microcomputer system used to control various electronic devices and systems. The MCU sends Manchester-coded pulse waves to the sensor array. These pulse waves carry the sensor's position information, and after processing by the sensor's circuitry, the corresponding conditioning circuitry generates a level signal that is fed back to the MCU. The MCU then obtains pulse information based on this level signal, including pulse length, number, and the corresponding sensor and its location. Algorithms are used to analyze and process the pulse information to obtain the position and tilt angle of the fabric on the laying machine, thereby enabling the fabric to be positioned and adjusted.

[0061] In this embodiment, Manchester-coded pulse waves are sent to each sensor in the sensor array, and the level signals fed back by each sensor are received. The level signals are analyzed to obtain pulse information, including the position of the corresponding sensor, and then the position and tilt angle of the fabric are obtained using the pulse information. This fabric laying machine edge alignment method can support multi-channel sensor signal transmission and reception, improving response speed and efficiency. It automatically obtains the precise position and tilt angle of the fabric using the received pulse information, facilitating real-time control of the fabric laying machine during the laying process.

[0062] In one embodiment of this application, the sensor array includes four columns of eight infrared light sensors.

[0063] Among some possible implementations, Figure 3 The diagram shown is a schematic representation of the sensor described in an embodiment of this application. Figure 3 As shown, the sensor array includes eight infrared sensors in four columns. Each sensor is equipped with a signal transmitting and receiving device, and each transmitting device is surrounded by a receiving device to determine the location of the fabric by the length and number of pulse signals and the position of the corresponding sensor. Specifically, the transmitting device is identified by encoding or duty cycle, and the receiving device is identified by encoding to determine which transmitting device emitted the infrared light.

[0064] In one embodiment of this application, the analysis and processing of the pulse information to obtain the position and tilt angle of the cloth includes: analyzing and processing the pulse information using a Lagrange interpolation algorithm to obtain a first position and a second position of the cloth; and using the first position and the second position to obtain the position and tilt angle of the cloth.

[0065] Among some possible implementations, Figure 4 The diagram shown illustrates the edge-aligning method of the fabric spreading machine described in an embodiment of this application. Figure 4 As shown, each sensor in the sensor array is equipped with a transmitting and receiving device, and each transmitting device is surrounded by three receiving devices. Figure 5 The diagram shown is a schematic representation of obtaining the tilt angle as described in an embodiment of this application. Figure 5 As shown, after receiving the level signal, the MCU uses the level signal to obtain pulse information. Lagrange interpolation is performed on the pulse information, and the first position X1 and the second position X2 are obtained by detecting the number of obstructions of each sensor. The distance of the fabric from the center of the sensor array and the tilt angle of the fabric are obtained using the first and second positions.

[0066] In one embodiment of this application, the fabric laying machine edge alignment method further includes: obtaining the distance between the fabric and the center of the sensor array based on the position of the fabric and the tilt angle; and adjusting the fabric edge alignment using the tilt angle and the distance between the fabric and the center of the sensor array.

[0067] Specifically, the distance between the fabric and the center of the sensor array is obtained based on the stated position and the tilt angle. Since the length and width of the sensor array are preset, the offset distance and direction of the fabric are determined using the tilt angle and the distance between the fabric and the center of the sensor array, thereby adjusting the edges of the fabric. This application is not limited to this.

[0068] In one embodiment of this application, sending a Manchester-coded pulse wave to a sensor array and receiving multiple level signals fed back by the sensor array includes: sending the Manchester-coded pulse wave to each sensor of the sensor array; and modulating the Manchester-coded pulse wave using the circuitry of the sensor array to receive the level signals fed back by each sensor of the sensor array.

[0069] In one embodiment of this application, the transmission of the Manchester-coded pulse wave by each sensor in the sensor array further includes: transmitting the Manchester-coded pulse wave to any sensor in the sensor array; determining whether valid level signals are received from the sensor and adjacent sensors to determine the occlusion information of the fabric on the sensor; and obtaining the position and tilt angle of the fabric based on the occlusion information. Wherein, the valid level signal is the level signal indicating that the fabric is occluded; if the fabric is not occluded, the corresponding level signal is an invalid level signal.

[0070] In some possible implementations, the eight sensors in four columns of the sensor array are numbered, and the position of each sensor is obtained. The sensors in the sensor array receive Manchester-coded pulse signals, which are processed by a first phase-controllable constant current source and then input to a light guide tube. The light guide tube then passes through a photoelectric conversion circuit and a comparator circuit to obtain the corresponding conditioning circuit. The MCU enables the transmission of Manchester-coded pulse waves to the first sensor in the first column of the sensor array, determines whether the conditioning circuit receives a valid level signal, and thus determines the occlusion information of the fabric on the sensor; based on the occlusion information, the position and tilt angle of the fabric are obtained.

[0071] In one embodiment of this application, sending the Manchester-coded pulse wave to a sensor of the sensor array includes:

[0072] The Manchester-coded pulse wave is sent to the first sensor in the first column of the sensor array. It is then determined whether a valid level signal is received from the first sensor in the first column. If so, the Manchester-coded pulse wave is sent to the second sensor in the first column of the sensor array.

[0073] Determine whether a valid level signal is received from the sensor. If yes, confirm that all sensors are blocked. If no, send the Manchester-coded pulse wave to the next column of sensors in the sensor array until the position and tilt angle of the cloth are obtained.

[0074] In some possible implementations, the sensors in the sensor array receive Manchester-coded pulse signals, which are then processed by a first phase-controllable constant current source and input into a light guide tube. The light guide tube then passes through a photoelectric conversion circuit and a comparator circuit to obtain the corresponding conditioning circuit. The conditioning circuits corresponding to the eight sensors in four columns and two rows are numbered as follows: the five conditioning circuits in the first row are numbered 1-5, and the five conditioning circuits in the second row are numbered 6-10.

[0075] Figure 6 The diagram shown is a flowchart illustrating the edge-aligning method of the fabric laying machine described in an embodiment of this application. Figure 6 As shown, the MCU enables the sending of Manchester-coded pulse waves to the first sensor in the first column of the sensor array, and determines whether conditioning circuits 1 and 2 receive a valid level signal. If a valid level signal is received, the MCU enables the sending of Manchester-coded pulse waves to the second sensor in the first column of the sensor array, and determines whether conditioning circuit 6 receives a valid level signal. If yes, it confirms that all sensors are blocked and the fabric is in the center of the fabric spreading machine. If yes, it determines whether conditioning circuit 7 receives a valid level signal. If yes, it confirms that the fabric is between conditioning circuits 6 and 7, obtains the distance and tilt angle θ between the fabric and the center of the sensor array, calculates the center position of the fabric using the tilt angle θ, and enables the fabric spreading machine to drive the fabric to the center position.

[0076] If conditioning circuit 7 does not receive a valid level signal, the MCU enables the sending of Manchester-coded pulse waves to the second sensor in the third column of the sensor array. It then determines whether conditioning circuit 8 has received a valid level signal. If so, it determines whether conditioning circuit 7 has received a valid level signal. If so, it determines that the position must be between conditioning circuits 6 and 7, calculates the distance between the fabric and the center of the sensor array and the tilt angle θ, calculates the center position of the fabric using the tilt angle θ, and enables the fabric laying machine to drive the fabric to the center position.

[0077] It should be noted that the above is only one possible implementation of the embodiments of this application, and this application is not limited thereto.

Figure 7 As shown, the fabric spreading machine edge-aligning system 100 includes a signal transceiver module 110, a signal parsing module 120, and an information processing module 130.

[0079] The signal transceiver module 110 is used to send Manchester-coded pulse waves to the sensor array and receive multiple level signals fed back by the sensor array.

[0080] The signal analysis module 120 is used to obtain pulse information based on the level signal. The pulse information includes pulse length, number, and the position of the corresponding sensor.

[0081] The information processing module 130 is used to analyze and process the pulse information to obtain the position and tilt angle of the cloth.

[0082] In some possible implementations, the microcontroller unit (MCU) serves as an integrated microcomputer system used to control various electronic devices and systems. The signal transceiver module 110 is used by the MCU to send Manchester-coded pulse waves to the sensor array. These Manchester-coded pulse waves carry sensor position information, and after processing by the sensor circuitry, the corresponding conditioning circuitry obtains a level signal that is fed back to the MCU. The signal analysis module 120 is used by the MCU to obtain pulse information based on the level signal, including pulse length, number, and the corresponding sensor and its location. The information processing module 130 uses algorithms to analyze and process the pulse information to obtain the position and tilt angle of the fabric on the laying machine, thereby positioning and adjusting the fabric.

[0083] In this embodiment, the signal transceiver module 110 is used to send Manchester-coded pulse waves to each sensor in the sensor array and receive the level signals fed back by each sensor. The signal analysis module 120 is used to analyze the level signals to obtain pulse information, including the position of the corresponding sensor. The information processing module 130 is used to obtain the position and tilt angle of the fabric using the pulse information. This fabric laying machine edge alignment system 100 can support multi-channel sensor signal transmission and reception, improve response speed and efficiency, and automatically obtain the precise position and tilt angle of the fabric using the received pulse information, facilitating real-time control of the fabric laying machine during the laying process.
