[0002] In the field of laser processing technology, batch processing can improve processing efficiency. Laser processing equipment (such as laser engraving and cutting machines) is widely used in marking, engraving, cutting, etc. of various materials. In order to achieve efficient processing, traditional laser processing systems usually use conveying devices such as conveyor belts to continuously transport the materials to be processed to the processing area of ​​the laser processing equipment for processing. However, there are still some problems in practical applications. For example, in a longer processing area, after completing the processing of a batch of materials, it is necessary to manually rearrange the next batch of materials to be processed, and manually fill in the processing pattern before processing, and then process, which leads to low laser processing efficiency.

[0064] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0065] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0067] It should be noted that, in this article, step codes such as S100, S200, etc. are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial limitation on the sequence. When implementing the step, those skilled in the art may execute S200 first and then S100, etc., but these should all be within the scope of protection of this application.

[0068] It should be noted that the gray areas in the drawings in this specification are only for easy identification and do not constitute technical features in this field.

[0069] In the related art, there are usually two types of laser processing equipment. One type of laser processing equipment is without a conveyor. During laser processing, multiple materials to be processed can only be placed on a processing surface for processing. After each processing is completed, the next batch of processing materials are rearranged, and the laser processing efficiency is low. In the field of laser processing technology, batch processing can improve production efficiency. In order to achieve efficient batch processing, another type of laser processing system usually uses a conveyor to continuously transport the materials to be processed to the processing surface of the laser processing equipment for processing. However, there are still some problems in practical applications. For example, in a longer processing area, after completing the processing of a batch of materials, it is necessary to manually rearrange the next batch of materials to be processed, and manually fill in the processing pattern and process. It is necessary to meet the requirements that the materials to be processed on the conveyor must be in the same direction, and the intervals between the materials to be processed must be equal. These requirements lead to the need to make different conveyor devices when processing different materials to be processed, that is, different conveyor structures need to be replaced when engraving different materials, and the processing cost is high and the operation is inconvenient.

[0070] To this end, the present invention proposes a laser processing method, referring to Figure 1 , the laser processing method comprises:

[0071] Step S100, acquiring a first image including a first area on the transmission device 100;

[0072] Step S200: Based on the reference processing material and the processing pattern on the reference processing material, fill the processing pattern on the target material to be processed in the first image, so that the laser processing equipment 300 processes the target material to be processed on the first area, and the target material to be processed is a material to be processed that matches the reference processing material;

[0073] Step S300, after the target material to be processed in the first area on the conveying device 100 is processed, controlling the conveying device 100 to move a preset distance so that the second area on the conveying device 100 is located within the processing width of the laser processing equipment 300;

[0074] Step S400, acquiring a second image including a second area on the conveying device 100, and filling the processing pattern on the target material to be processed in the second image, so that the laser processing equipment 300 processes the target material to be processed on the second area.

[0075] In this embodiment, please combine Fig.11The laser processing method of the present invention can be applied to the laser processing device 300 or the terminal device 200. For example, the terminal device 200 is integrated with a memory for storing the laser processing control program of the present invention and a processor for executing the laser processing control program of the present invention. The processor can be implemented by a main controller, such as MCU, DSP (Digital Signal Process), FPGA (Field Programmable Gate Array), PLC, SOC (System On Chip), etc.

[0076] It is understandable that the laser processing equipment 300 includes laser marking machines, laser engraving machines, laser cutting machines, laser welding machines and other equipment. The terminal device 200 includes a computer, a mobile phone, a tablet and the like. The laser processing equipment 300 can establish a connection with the terminal device via the communication circuit 50, and the user controls the operation of the laser processing equipment 300 by operating the terminal device to improve the convenience of operation. Among them, the communication circuit 50 can be implemented by a wired communication module, such as a LIN communication module, a CAN communication module, an RS485 transceiver chip, etc., and the corresponding bus type is selected according to the communication module. The communication circuit 50 can also be implemented by a wireless communication module, such as a WiFi module, a Bluetooth communication module, a 4G / 5G module, etc.

[0077] It should be noted that in laser processing technology, in order to control the laser beam to accurately process the material to be processed, it is crucial to determine the position of the material to be processed. In this embodiment, a visual positioning system can be used, for example, the terminal device can capture the first image corresponding to the material to be processed in the first area on the conveying device 100 (including the conveying device) by controlling the camera 20 in the laser processing device 300, and cooperate with the image processing software in the control device to identify or mark, so as to accurately locate the position of the material to be processed on the conveying device; optionally, a high-precision CCD (Charqe-Coupled Device) camera can be set on the laser processing device 300, and the contour of the material to be processed or a pre-set reference mark can be captured by the camera, so as to dynamically adjust the position of the laser head on the laser processing device 300; optionally, the geometric shape and position of the material to be processed can be measured by a contact probe measuring instrument before or during processing, and the corresponding measurement signal can be output to the control device, so that the control device controls the position and direction of the laser head according to the received measurement signal.

[0078] Optionally, after step S200 and before step S300, the laser processing method further includes: controlling the laser processing device 300 to process the target material to be processed on the first area. Specifically, the target material to be processed on the first area can be processed based on the first image and the processing pattern on the first image.

[0079] Optionally, the reference processing material is obtained by the following steps:

[0080] At least one to-be-processed material filled with the processing pattern is determined as the reference processing material based on the first image.

[0081] Specifically, taking the establishment of a communication connection between the terminal device and the laser processing device 300 as an example, after the terminal device acquires the first image, the user can arbitrarily select a material to be processed from the materials to be processed in the first image as a reference processing material, and place a pre-stored or pre-received processing pattern on the reference processing material in the first image, so that the terminal device can determine at least one material to be processed filled with the processing pattern as the reference processing material based on the reference processing material and the processing pattern on the reference processing material, and fill the processing pattern on the target material to be processed in the first image. Specifically, the processing pattern and the positions of multiple materials to be processed can be identified, and then the material to be processed filled with the processing pattern can be determined based on the processing pattern and the positions of multiple materials to be processed, and it can be determined as the reference processing material.

[0082] It should be noted that after the filling is completed, the terminal device will generate a corresponding processing file and send it to the laser processing device 300, and control the laser processing device 300 to process the corresponding material to be processed in the first area on the conveying device 100. For example, the user can preview the effect of the processing pattern on the actual material to be processed in the terminal device software, and save the working path or generate a processing program. Then the laser processing device 300 is controlled to process the material to be processed in the first area on the conveying device 100. After the target material to be processed in the first area is processed, the terminal device controls the conveying device 100 to move a preset distance, which can be the distance of at least one processing format, and then controls the camera 20 to shoot the processing format on the conveying device 100 to obtain a second image, and fills the processing pattern for the target material to be processed in the second image, so as to control the laser processing device 300 to process the target material to be processed in the second area. In this way, batch processing of multiple materials to be processed located in the processing format is achieved.

[0083] It should be noted that by acquiring the first image, the second image, etc. uploaded by the camera 20, the position information of the material to be processed can be determined. For example, the actual position information of the material to be processed on the conveying device is calculated according to the mapping relationship between the image and the laser processing equipment 300, and then the angle and direction of the laser head of the laser processing equipment 300 are controlled according to the actual position information, thereby controlling the laser processing equipment 300 to process the material to be processed. The physical position of the material to be processed can also be converted into the coordinate system of the laser processing equipment 300, that is, a unified reference frame is established, and the position of the material to be processed in the unified coordinate system is determined, thereby controlling the laser processing equipment 300 to process the material to be processed. Optionally, the actual position of the material to be processed can also be obtained in real time through a visual system, a contact probe (probe), an optical sensor, an electromagnetic sensor, etc., and fed back to the terminal device, so that the terminal device outputs a corresponding control signal to the controller 30 of the laser processing equipment 300, thereby controlling the movement trajectory of the laser head. In addition, taking into account the signal delay, when the first area or the next area of ​​the conveying device 100 enters the processing area of ​​the laser processing equipment 300, the camera 20 is controlled to shoot and the conveying device is controlled to stop rotating to avoid changes in the position of the material to be processed on the conveying device, which causes an offset between the actual position and the acquired position, so as to ensure the accuracy of the acquired position information as much as possible, thereby ensuring the processing effect and accuracy of the laser processing equipment 300.

[0084] In practical applications, the camera 20 can be used to photograph multiple materials to be processed on the conveying device, so as to obtain the position information of the materials to be processed based on the photographed images, and fill the processing pattern to be engraved on the target materials to be processed on the image in the software corresponding to the terminal device, and after filling, the reference processing material and the target materials to be processed of the same type are processed. In this way, a batch operation of first filling and then processing the target materials to be processed in different areas of the conveying device 100 is realized, which improves the processing efficiency and the convenience of operation. Compared with the related art, the user can place multiple materials to be processed on the conveying device at will. The laser processing method of the present invention can obtain the images corresponding to the materials to be processed on the conveying device, and then obtain the actual position information of the materials to be processed on the processing surface. No manual calibration is required, and the accuracy is high. It improves the problems of the same direction of the materials to be processed on the conveying device and the intervals between the materials to be processed, and improves the processing efficiency. In addition, in the process of obtaining position information to controlling the laser processing equipment 300 for processing, the conveying device is in a stationary state, and there is no need to worry about processing errors caused by position changes. Therefore, there is no need to set different grooves or clamps at different distances on the conveying device for different shapes of materials to be processed. That is, for different types of materials to be processed, there is no need to replace different conveying structures to adapt, which reduces the processing cost to a certain extent and improves the operating convenience and user experience.

[0085] In one embodiment of the present invention, reference Figure 2 The step of acquiring a first image of a first area on the transmission device 100 specifically includes:

[0086] Step S110, controlling the camera 20 of the laser processing equipment 300 to photograph the first area to obtain the first image;

[0087] Step S120 , receiving the first image transmitted by the laser processing equipment 300 .

[0088] It is understandable that in order to accurately obtain the actual position and size of the material to be processed on the conveying device and obtain dynamic tracking and positioning, a visual system is usually installed in conjunction with the laser head on the laser processing equipment 300, and the camera 20 can be set next to the laser head to cooperate with the laser head. Among them, the camera 20 includes any one of a CCD camera, an infrared camera, a line scan camera, a surface array camera, and a 3D camera. In this embodiment, the camera 20 is installed next to the laser head of the laser processing equipment 300, and the camera 20 is connected to the controller 30 of the laser processing equipment 300. The controller 30 is used to control the working state of the camera 20 so that the camera 20 captures multiple materials to be processed on the conveying device to obtain image information of the materials to be processed. For example, the camera 20 of the laser processing equipment 300 is controlled to shoot the first area on the conveying device 100, and the laser processing equipment 300 will transmit the first image obtained by shooting to the terminal device, and the terminal device receives the first image transmitted by the laser processing equipment 300, so that the user can use the relevant software of the terminal device to fill the processing pattern required for processing in the first image for the target material to be processed. Specifically, when the control device obtains the first image captured by the camera 20, the first image is used as a base map in the software interface related to the terminal device, that is, the user can directly edit the processing pattern on the first image through the terminal device to complete the work of filling the target pattern to be processed on the first image. For example, the user can place the processing pattern on any material to be processed on the editable base map according to the preset processing parameters, and use the material to be processed filled with the processing pattern as the reference processing material. In this way, the terminal device can fill the processing pattern on the target material to be processed in the first image based on the reference processing material and the processing pattern on the reference processing material. Among them, the preset processing parameters include the angle and position relationship of the processing pattern on the material to be processed. In this way, the user can intuitively preview the effect of the processing pattern on the actual material to be processed in the terminal device. If the user finds that the processing pattern edited according to the preset processing parameters has a large offset in the position on the material to be processed, the user can also directly adjust the preset processing parameters in the terminal device, thereby changing the angle and position between the pattern to be processed and the material to be processed on the first image, thereby obtaining a better processing effect. In addition, the user can also determine whether the captured image is wrong through the terminal device after the camera 20 shoots. If the image does not contain image information of all the materials to be processed under the laser head (processing format), it may be that some materials to be processed have not entered the processing format under the laser head or have not fully entered it, and are at the edge of the processing format. The user can operate the terminal device to output corresponding control signals to the laser processing equipment 300 according to actual conditions, so that the controller 30 of the laser processing equipment 300 controls the conveying device to move a certain distance, and controls the camera 20 to re-shoot.In this way, it can be ensured that the position information obtained by the control device is the position information of all the materials to be processed within the processing width, avoiding the problem that the position information obtained based on the image information is inconsistent with the actual position information of the materials to be processed on the conveying device, resulting in the inability to process normally or the materials to be processed that do not appear in the image are not processed, thereby improving the processing accuracy.

[0089] It should be noted that the conveying device 100 and the laser processing device 300 can be two separate devices; or the laser processing device 300 and the conveying device 100 are integrally arranged, and the conveying device 100 is controlled by the controller 30 of the laser processing device 300. When the conveying device 100 and the laser processing device 300 are two separate devices, the terminal device 200 can be respectively connected to the conveying device 100 and the laser processing device 300 for communication. When the image does not contain the image information of all the materials to be processed in the processing format, the user can operate the terminal device to output the corresponding control signal to the conveying device 100 according to the actual situation, so as to control the conveying device to move a certain distance and control the camera 20 to re-shoot.

[0090] In practical applications, a visual system is used to set the camera 20 at a preset position of the laser head to capture the image information of the material to be processed within the processing format of the laser processing equipment 300, thereby improving the accuracy of the position information of the material to be processed, thereby improving the processing efficiency and processing accuracy. At the same time, the terminal device can fill the processing pattern on the target material to be processed in the first image based on the reference processing material and the processing pattern on the reference processing material, so as to facilitate subsequent processing. The user can also intuitively see the image information of the material to be processed in the terminal device, and preview the processing effect of the processing pattern on the material to be processed, so as to adjust the preset processing parameters in time, thereby improving the processing effect.

[0091] In one embodiment of the present invention, reference Figure 3 The acquiring of the second image of the second area on the transmission device 100 specifically includes:

[0092] Step S010, controlling the camera 20 of the laser processing equipment 300 to photograph the second area to obtain the second image;

[0093] Step S020 , receiving the second image transmitted by the laser processing equipment 300 .

[0094] In combination with the contents of the above embodiments, after the terminal device fills the material to be processed on the first image and processes the material to be processed in the first area according to the filled processing pattern, the conveying device 100 is controlled to move a preset distance so that the second area on the conveying device 100 is located within the processing format of the laser processing equipment 300, and then the terminal device controls the camera 20 of the laser processing equipment 300 to shoot the second area on the conveying device 100. The laser processing equipment 300 transmits the captured second image to the terminal device. The terminal device receives the second image transmitted by the laser processing equipment 300, so that the user can use the relevant software of the terminal device to fill the processing pattern to be processed for the target material to be processed in the second image.

[0095] It is understandable that after the laser processing equipment 300 completes processing of the materials to be processed in the first area, the laser processing equipment 300 can output a corresponding feedback signal to the terminal device to report the completion status. The terminal device determines that the processing is completed according to the received feedback signal, and outputs a corresponding control signal to the controller 30 of the laser processing equipment 300 to control the conveying device to move a preset distance, so that the next batch of materials to be processed (materials to be processed in the second area) stops moving when reaching the processing width of the laser processing equipment 300, so that the camera 20 obtains the second image and uploads it to the terminal device, so that the laser processing equipment 300 can process the target materials to be processed in the second area. Among them, the preset distance is the distance between the current material to be processed and the next batch of materials to be processed, or the distance between the previous batch of materials to be processed and the current material to be processed. Since the user can randomly place each batch of materials to be processed on the conveying device, the preset distance of the conveying device movement can be different in each batch processing, or the preset distance is the distance of the processing width of the laser processing equipment 300. The camera 20 can automatically identify each batch of materials to be processed entering the processing area, take pictures in time and upload them to the terminal device 200.

[0096] Specifically, when the terminal device obtains the second image captured by the camera 20, the second image is used as a base map in the software interface related to the terminal device, that is, the user can directly edit the processing pattern on the second image through the terminal device to complete the work of filling the target pattern to be processed on the second image. For example, the user can place the processing pattern on any material to be processed on the editable base map according to the preset processing parameters, and use the material to be processed filled with the processing pattern as the reference processing material. In this way, the terminal device can fill the processing pattern on the target material to be processed in the second image based on the reference processing material and the processing pattern on the reference processing material, and control the laser processing device 300 to process the target material to be processed in the second area after the filling is completed. Similarly, after the target material to be processed in the second area of ​​the laser processing device 300 is processed, the conveying device 100 is controlled to move a preset distance so that the third area of ​​the conveying device 100 is located within the processing format, and the camera 20 is controlled to shoot the third area to obtain a third image, receive the third image, fill the corresponding processing pattern for the target material to be processed in the third image, and then control the laser processing device 300 to process the target material to be processed on the third area. In this way, the cycle is repeated until the processing of the target materials to be processed in all areas on the conveying device is completed, or when a stop processing instruction triggered by the user is received, the laser processing equipment 300 is controlled to stop processing.

[0097] It should be noted that, when acquiring the reference processing material, the control device may respectively calculate the relative position information between the reference processing material and the remaining target materials to be processed, so as to acquire the position information of multiple target materials to be processed.

[0098] In this embodiment, reference Fig. 9 After the terminal device establishes a communication connection with the laser processing device 300 via the communication circuit 50, the terminal device outputs a corresponding control signal to the controller 30 of the laser processing device 300, so that the controller 30 controls the camera 20 to work and receive the image transmitted by the laser processing device 300. It can be understood that, referring to Fig.10 When the user arbitrarily places multiple materials to be processed on the conveying device under the laser head of the laser processing equipment 300, the image information obtained by the camera 20 includes image information corresponding to the multiple materials to be processed. The user can arbitrarily select one material to be processed from the multiple materials to be processed in the image as a reference processing material through the terminal device, so that the terminal device uses the reference processing material as a reference to calculate the relative position information of the remaining target materials to be processed and the reference processing material in the current editable base map, and calculate the actual position information of the materials to be processed on the conveying device according to the mapping relationship between the image information and the laser processing equipment 300, and then control the working angle and direction of the laser head according to the actual position information, thereby controlling the laser processing equipment 300 to process the materials to be processed.

[0099] Specifically, when the terminal device receives the image uploaded by the laser processing device 300, the terminal device can use the image captured by the camera 20 as an editable base map, so that the user can intuitively perform corresponding editing on the base map, for example, placing the preset processing pattern on the reference processing material. In this way, no matter how many materials to be processed the user places, only one needs to be selected on the editable base map as the recognition prototype. After the user edits the preset processing pattern to the reference processing material, the base map and the position of the processing pattern can be used for calculation to obtain the relationship between the processing pattern and the reference processing material, such as the angle and position, and the relative position information between the reference processing material on the base map and the other target processing materials to be processed, and then obtain the actual angle and position of the processing pattern and the material to be processed corresponding to the reference processing material, and the actual relative position of the material to be processed corresponding to the reference processing material and the other target processing materials to be processed, so as to control the laser processing device 300 to process according to the acquired position information. Among them, the preset processing pattern is set in advance by the R&D personnel. The relative position information between the reference processed material and the remaining target materials to be processed calculated based on the image corresponds one to one with the relative position information between the material to be processed corresponding to the reference processed material on the conveying device and the remaining target materials to be processed.

[0100] refer to Figure 7 For example, if the processing area of ​​the laser head is set to 220mm×220mm, it can be converted into a plane coordinate system (X0, Y0) to (X220, Y220). Since the camera 20 is set at the preset position of the laser head, and the processing area of ​​the laser head is set directly below the laser head, when the material to be processed is transported to the processing area by the conveyor, the photo taken by the camera 20 is actually an inclined picture relative to the angle of the laser head. Therefore, the terminal device performs processing such as lifting and correction on the image obtained by the camera 20 to convert it into a view directly below the laser head; and then calculates the view of 220mm×220mm at the cutting position according to the plane height from the laser head to the processing area on the conveyor, wherein the plane height of the laser head and the processing area is a fixed value. At this time, the position of each material to be processed on the base map can correspond to a certain position and range on the plane coordinate system. Therefore, the actual position information of multiple materials to be processed can be obtained according to the image obtained by the camera 20, so that the laser processing equipment 300 can process the materials to be processed.

[0101] Through the above-mentioned settings, the laser processing method of the present invention makes one-to-one correspondence between the image information acquired by the camera 20 and the actual position information of the material to be processed. While accurately acquiring the actual position of the material to be processed on the conveying device, the user only needs to control the working status of the camera 20 through the terminal device, without the need for unnecessary operating steps, thereby improving user convenience.

[0102] In one embodiment, there are at least two reference processing materials, and the step of filling the processing pattern on the target material to be processed in the first image based on the reference processing material and the processing pattern on the reference processing material specifically includes:

[0103] Based on the at least two reference processing materials and the processing patterns on the at least two reference processing materials, the corresponding processing patterns are filled in the first image for at least two target materials to be processed that match the at least two reference processing materials.

[0104] It should be noted that the same area of ​​the conveying device 100 may include at least two types of materials to be processed, and the laser processing method of the present invention can process different types of materials to be processed at the same time.

[0105] In combination with the above embodiments, after the laser processing device 300 controls the camera 20 to shoot the area of ​​the conveying device corresponding to the processing format of the laser processing device 300, the terminal device 200 will receive the image transmitted by the laser processing device 300. When the image includes two types of materials to be processed, for example, there are two types of materials in the image: dog tags and business cards, which are marked as Class A and Class B respectively. The user can select a dog tag as a reference processing material for Class A materials on the editable base map through the relevant software interface of the terminal device, and place a pattern to be processed (such as a pet name) on it. And select a business card as a reference processing material for Class B materials, and place a processing pattern to be processed (such as a company name) on it. Based on the two reference processing materials and the processing patterns on the two reference processing materials, the terminal device fills the corresponding processing patterns for the two target materials to be processed that match the two reference processing materials in the image. That is, the terminal device fills in the corresponding pet name for the target material to be processed that matches the class A material in the base map based on the reference processing material of the class A material and the processing pattern of the class A material, and fills in the corresponding company name for the target material to be processed that matches the class B material in the base map based on the reference processing material of the class B material and the processing pattern of the class B material. After the user confirms that it is correct, the terminal device generates the corresponding processing file and sends it to the laser processing device 300. The laser processing device 300 processes all the target materials to be processed (including dog tags and business cards) in the processing format in sequence according to the received processing file. When the processing is completed, the terminal device sends an instruction to the controller 30 to control the conveying device to move a preset distance so that the next area enters the processing format.

[0106] It should be noted that the materials to be processed placed on the conveying device in the same batch can be the same. If the image information acquired by the camera 20 includes at least two materials to be processed, when the user selects a material to be processed as a reference processing material, the terminal device 200 will only fill in the target material to be processed that matches the reference processing material, and after the filling is completed, it will send the corresponding processing file to the controller 30 of the laser processing equipment 300 through the communication circuit 50, so that the controller 30 controls the laser head to process the target material to be processed that matches the reference processing material.

[0107] The technical solution of the present invention can process multiple types of materials to be processed at the same time without changing different conveying structures. Through automatic identification and classification, the efficiency of batch processing is greatly improved. The user only needs to select the reference processing material and place the processing pattern in the terminal device, and the terminal device 200 can automatically complete the filling and processing operations. In this way, the production efficiency and operational convenience are significantly improved.

[0108] In one embodiment, reference Figure 4 The step of filling the processing pattern on the target material to be processed in the first image based on the reference processing material and the processing pattern on the reference processing material specifically includes:

[0109] Step S210: filling the processing pattern on the target material to be processed in the first image based on the relative position relationship between the processing pattern and the reference processing material;

[0110] Step S220: the target material to be processed includes a material to be processed whose contour similarity with the reference material to be processed is greater than a preset threshold, and distribution of the processing pattern on the reference material to be processed is the same as distribution of the processing pattern on the target material to be processed.

[0111] In combination with the above-mentioned embodiments, after the terminal device receives the first image transmitted by the laser processing device 300, the user can select a reference processing material on the first image through the relevant software interface of the terminal device, and place the pre-selected processing pattern at the position corresponding to the reference processing material. In this way, the terminal device can obtain the relative position information between the processing pattern and the reference processing material, so that the processing pattern is filled on the materials to be processed that match the reference processing material in the first image. It should be noted that the terminal device will classify the materials to be processed whose contour similarity with the reference processing material in the first image is greater than the preset threshold as the target materials to be processed that match the reference processing material, and will fill the target materials to be processed based on the relative position relationship between the processing pattern and the reference processing material, so that the distribution of the processing pattern on the reference processing material is the same as the distribution of the processing pattern on the target materials to be processed. Among them, the preset threshold is set in advance by the R&D personnel. For each material to be processed in the same processing width, the terminal device calculates its contour similarity with the reference processing material. Assuming that the preset threshold is 80%, only when the contour similarity of the material to be processed is greater than 80%, it will be identified as the target material to be processed.

[0112] It should be noted that the relative position relationship includes one or more combinations of relative angle information, coordinate relationship between the center point of the processing pattern and the center point of the reference processing material. After identifying the reference processing material determined by the user and the placed processing pattern, the terminal device can optionally calculate the relative angle information between the processing pattern and the reference processing material, so as to fill the processing pattern at the position corresponding to the target material to be processed, and the relative angle information between the material to be processed and the processing pattern after filling is the same as the relative angle information between the processing pattern and the reference processing material. Optionally, the terminal device can calculate the coordinate relationship between the center point of the processing pattern and the center point of the reference processing material, and fill the processing pattern at the position corresponding to the target material to be processed based on the coordinate relationship, and the coordinate relationship between the center point of the material to be processed after filling and the center point of the processing pattern is equal to the coordinate relationship between the center point of the processing pattern and the center point of the reference processing material. Take the relative position relationship including the coordinate relationship between the center point of the processing pattern and the center point of the reference processing material as an example, first determine the center point coordinates of each target material to be processed (dog tag), and then compare with the center point coordinates of the reference processing material. For example, the center point of the processing pattern is 2 mm to the right and 3 mm to the bottom of the reference dog tag (reference processing material). The terminal device will move the center point of another dog tag 2 mm to the right and 3 mm to the bottom as the center point of the processing pattern, and fill the processing pattern for the dog tag.

[0113] This not only improves processing accuracy, but also reduces manual intervention, ensuring processing consistency and reliability.

[0114] In one embodiment, reference Figure 5 , the step of filling the processing pattern on the target material to be processed in the second image specifically includes:

[0115] Step S410: filling the processing pattern on the target material to be processed in the second image based on the relative position relationship between the processing pattern and the reference processing material;

[0116] Step S420: the target material to be processed includes a material to be processed whose contour similarity with the reference material to be processed is greater than a preset threshold, and distribution of the processing pattern on the reference material to be processed is the same as distribution of the processing pattern on the target material to be processed.

[0117] In combination with the above-mentioned embodiment, after the terminal device receives the second image transmitted by the laser processing device 300, the user can select a reference processing material on the second image through the relevant software interface of the terminal device, and place the pre-selected processing pattern at the position corresponding to the reference processing material. In this way, the terminal device can obtain the relative position information between the processing pattern and the reference processing material, so that the processing pattern is filled on the materials to be processed that match the reference processing material in the second image. It should be noted that the terminal device will classify the materials to be processed whose contour similarity with the reference processing material in the second image is greater than the preset threshold as the target materials to be processed that match the reference processing material, and will fill the target materials to be processed based on the relative position relationship between the processing pattern and the reference processing material, so that the distribution of the processing pattern on the reference processing material is the same as the distribution of the processing pattern on the target materials to be processed. Among them, the preset threshold is set in advance by the R&D personnel. For each material to be processed within the same processing width, the terminal device calculates its contour similarity with the reference processing material. Assuming the preset threshold is 80%, only when the contour similarity of the material to be processed is greater than 80%, it will be identified as the target material to be processed.

[0118] Taking the relative position relationship including the angle information between the processing pattern and the reference processing material as an example, assume that the pet name is rotated 15 degrees counterclockwise relative to the bottom edge of the circular reference dog tag. For each target material to be processed (i.e., other circular dog tags), regardless of their actual placement angle, the terminal device will adjust the direction of the pet name according to the preset relative angle (rotated 15 degrees counterclockwise).

[0119] This not only improves processing accuracy, but also reduces manual intervention, ensuring processing consistency and reliability.

[0120] In another embodiment, after filling the processing pattern on the target material to be processed in the first image, the laser processing method further includes:

[0121] Generate a first processing file based on the position information of the filled processing pattern and the mapping relationship between the first area and the position information, and control the laser processing device 300 to process the target material to be processed in the first area based on the first processing file; and / or,

[0122] After filling the processing pattern on the target material to be processed in the second image, the laser processing method further includes:

[0123] A second processing file is generated based on the position information of the filled processing pattern and the mapping relationship between the second area and the position information, and the laser processing equipment 300 is controlled to process the target material to be processed in the second area based on the second processing file.

[0124] In combination with the contents of the above embodiments, when the terminal device 200 fills the processing pattern on the target material to be processed in the first image based on the reference processing material and the processing pattern on the reference processing material, the user can click "Start processing" on the terminal device, and the terminal device calculates the position information of the processing pattern through the first image and the position of the processing pattern, such as the angle, coordinates and other information of the processing pattern on the reference processing material, and then generates a first processing file based on the mapping relationship between the calculated position information of the processing pattern and the first area, that is, the actual physical position of the processing pattern relative to the laser processing equipment 300 is determined according to the mapping relationship set in advance, and then converted into a recognizable processing instruction, and the first processing file is generated accordingly and sent to the laser processing equipment 300. The laser processing equipment 300 is in a processing-ready state, and waits for the user to press the start button 40 of the laser processing equipment 300 (that is, equivalent to receiving the start instruction) before starting to process the target material to be processed. It should be noted that the first batch processing requires pressing the start button 40, and subsequent processing no longer requires pressing the start button 40. After pressing the start button 40 and waiting for a period of time, the laser processing equipment 300 processes all target materials to be processed in the first area in turn according to the received first processing file. When the processing is completed, the user can now place the same type of materials to be processed at the subsequent positions of the conveying device at will.

[0125] In this embodiment, when all target materials to be processed in the first area have been processed, the terminal device can determine that the processing is completed according to the feedback signal sent by the laser processing device 300, and send an instruction to the controller 30 to control the conveying device to move a preset distance so that the second area enters the processing area of ​​the laser processing device 300. The controller 30 of the laser processing device 300 drives the camera 20 to shoot the second area on the conveying device again, obtains a second image, and uploads it to the terminal device, so that after receiving the second image, the terminal device automatically fills the corresponding processing pattern for the target material to be processed in the second image based on the reference processing material selected by the user and the processing pattern on the reference processing material. Based on the position information of the filled processing pattern and the mapping relationship between the second area and the position information, the second processing file is directly generated and sent to the laser processing device 300 without receiving a user instruction, and the laser processing device 300 is controlled to start processing directly without pressing the button 40 for confirmation. For example, the terminal device determines the specific position of the processing pattern on each target material to be processed through an image processing algorithm, and calculates the actual position of the processing pattern relative to the coordinate system where the laser processing device 300 is located. These position information are then converted into machine-recognizable processing instructions, and a second processing file is generated and sent to the laser processing equipment 300, so that the laser processing equipment 300 can process all target materials to be processed in the second area in sequence according to the received second processing file.

[0126] Through the above scheme, according to the mapping relationship set in advance, the position information of the processing pattern is converted into a recognizable processing instruction, thereby generating a processing file, ensuring the consistency and accuracy of the processing pattern. In addition, during the first processing, the user needs to manually click the "Start Processing" button to ensure that the user confirms the initial settings. In this way, the possibility of misoperation is reduced and the accuracy of the first processing is improved. Once the first processing is started, the terminal device 200 can automatically process subsequent batches without pressing the start button 40 again, reducing the time of manual intervention and improving production efficiency.

[0127] In one embodiment, reference Figure 6 After acquiring the second image including the second area on the conveying device 100, the laser processing method further includes:

[0128] Step S500, identifying the target material to be processed in the second image;

[0129] Step S600: if it is recognized that the target material to be processed exists in the second image, the processing pattern is filled on the target material to be processed in the second image;

[0130] Step S700: If it is identified that the target material to be processed does not exist in the second image, control the conveying device 100 to move a preset distance to obtain a third image including a third area on the conveying device 100; if it is identified that the target material to be processed exists in the third image, fill the processing pattern on the target material to be processed in the third image.

[0131] refer to Figure 8Before starting the processing, the user needs to install the transmission device, for example, connect the transmission device and the laser processing device 300 through a connecting line, and open the terminal device and the laser processing device 300, that is, open the software installed in the windows or ios system, and obtain the WIFI communication module through the USB cable to establish a communication connection between the terminal device and the laser processing device 300. The user clicks to enter the batch processing mode through the terminal device, and the controller 30 of the laser processing device 300 will enable and power the transmission device to output the corresponding control signal to the transmission device to control the operation of the transmission device. At this time, the conveying device is in a stationary state. During the first processing, the terminal device outputs a corresponding control signal to the controller 30 of the laser processing device 300, so that the controller 30 controls the camera 20 to shoot the material to be processed within the processing format, obtain a first image, and upload the first image to the terminal device. The user can select a reference processing material from any material to be processed in the first image, and place the processing pattern at the corresponding position of the reference processing material, so that the terminal device fills the reference processing material, and identifies at least one material to be processed filled with the processing pattern as the reference processing material, and then fills the processing pattern on the target material to be processed in the first image based on the reference processing material and the processing pattern on the reference processing material. In order to improve the processing efficiency and processing accuracy, the user can intuitively edit the processing pattern on the first image through the terminal device, set the processing parameters and other contents, and after placing the processing pattern to be processed on the reference processing material, the user confirms that the processing pattern and position are correct, and clicks processing on the terminal device, so that the terminal device automatically fills the processing pattern on other target materials to be processed on the first image. After the filling is completed, the user clicks on the terminal device to start processing, and the processing file will be sent to the laser processing device. After the file is sent, the laser processing device is in a processing ready state, waiting for the user to press the start button 40 of the laser processing device; it should be noted that the first processing of batch processing requires pressing the start button 40, and the subsequent processing no longer requires pressing the start button 40. After pressing the start button 40 and waiting for a period of time, the processing is completed. At this time, the user can freely place the same type of materials to be processed at the subsequent position of the conveying device; that is, after the processing is completed, the terminal device sends a corresponding control instruction to the laser processing device 300, and the laser processing device 300 controls the conveying device to move a preset distance so that the conveying device moves a processing width distance. This width distance is the maximum area that the laser processing device can process, such as the processing width directly below the laser head. Then the terminal device sends a control instruction to enable the controller 30 to control the camera 20 to capture the second image of the second area and send it back to the terminal device for processing; the terminal device analyzes and processes the image, identifies whether there is a target material to be processed in the second image, and if there is a target material to be processed, fills the processing pattern for the target material to be processed in the second image.It is understandable that, based on the reference processing material selected by the user, if the terminal device does not identify the target material to be processed that matches the reference processing material in the second image, the laser processing device 300 can automatically exit the batch processing mode and process the reference processing material alone. Alternatively, the laser processing device 300 controls the conveyor device to move a preset distance so that the third area of ​​the conveyor device is located within the processing format, and obtains a third image of the third area on the conveyor device 100. If the target material to be processed that matches the reference processing material exists in the third image, the processing pattern is filled on the target material to be processed. If not, the conveyor device continues to move a preset distance until the target material to be processed that matches the reference processing material is identified in the image, so as to facilitate the filling and processing operations on the target material to be processed.

[0132] The laser processing method further comprises:

[0133] If the target material to be processed is not identified in N consecutive images, the laser processing device 300 is controlled to stop processing;

[0134] Alternatively, if a stop processing instruction is received, the laser processing equipment 300 is controlled to stop processing.

[0135] In order to reduce unnecessary repeated operations, when the target material to be processed is not identified in N consecutive images, that is, when the conveying device moves the preset distance for the preset number of times, and still does not identify the target material to be processed in the Nth image, it is determined that the user is not on site or does not have the processing requirements, and the batch processing state is automatically exited, and the laser processing equipment 300 is controlled to stop working. Among them, N is set in advance by the R&D personnel. It should be noted that if the target material to be processed is not identified in N consecutive images or at any stage of the processing flow, the user can manually exit the batch processing mode. That is, when the terminal device receives the stop processing instruction triggered by the user, it controls the laser processing equipment 300 to stop processing. If other types of processing materials need to be processed, the user can also control the laser processing equipment to exit the batch processing mode so as to re-enter the batch processing mode.

[0136] In practical applications, the laser processing method of the present invention requires the user to trigger the trigger device of the laser processing equipment 300 during the first processing, such as pressing the start button 40 to confirm the processing, which effectively avoids problems such as misoperation and potential safety hazards. In addition, it can automatically identify whether it is the same type of material to be processed, and automatically fill the same type of material to be processed, thereby improving the processing efficiency. It is also possible to control the shooting and identification process and the processing process separately, first shoot and identify through the camera 20, and then process the target material to be processed in the area directly below the laser head, thereby improving the reliability and accuracy of the laser processing equipment 300. And when the target material to be processed is not identified continuously, the batch processing mode is automatically exited, and the laser processing equipment 300 is controlled to stop working, thereby improving the safety of laser processing and the convenience of user operation.

[0137] The present invention proposes an electronic device, which includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program is configured to implement the steps of the laser processing method as described in any one of the above items.

[0138] Among them, the electronic device can be the above-mentioned terminal device, laser processing equipment 300, etc.

[0139] It is worth noting that since the electronic device of the present invention is based on the above-mentioned laser processing method, the embodiments of the electronic device of the present invention include all technical solutions of all embodiments of the above-mentioned laser processing method, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0140] The present invention proposes a laser processing device 300, which includes a processing head 10, a camera 20 and a controller 30;

[0141] The camera 20 is used to photograph the processing area of ​​the laser processing equipment 300 to obtain an image;

[0142] The controller 30 is used to receive a processing instruction generated by any of the laser processing methods described above, and control the processing head 10 to process the material to be processed located on the conveying device 100 based on the processing instruction.

[0143] In this embodiment, the controller 30 can be implemented by a main controller, such as MCU, DSP (Digital Signal Process), FPGA (Field Programmable Gate Array), PLC, SOC (System On Chip), etc. The processing head 10 includes a laser head, a cutting head, etc.

[0144] refer to Fig. 9 , the laser processing device 300 includes a controller 30, a button 40, a communication circuit 50, a processing head 10 and a camera 20. The controller 30 can control the camera 20 to shoot the processing format to obtain an image of any area of ​​the conveying device 100 located in the processing format, including a first image, a second image, etc. Optionally, when receiving the processing file sent by the terminal device 200, the controller 30 can parse the processing instruction based on the processing file, and control the processing head 10 to process the material to be processed in the processing format. Optionally, the laser processing device 300 can control the camera 20 to shoot an image and receive the image. After the laser processing device 300 receives the image, the user can determine the reference processing material and the processing pattern through the user input interface of the laser processing device 300, so that the laser processing device 300 fills the processing pattern on the target material to be processed in the image based on the reference processing material and the processing pattern on the reference processing material, and automatically generates a processing file after the filling is completed, and controls the processing head 10 to process the target material to be processed according to the processing file. In this way, the terminal device 200 does not need to participate, and the processing rate is improved.

[0145] It is worth noting that since the laser processing equipment 300 of the present invention is based on the above-mentioned laser processing method, the embodiments of the laser processing equipment 300 of the present invention include all technical solutions of all embodiments of the above-mentioned laser processing method, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0146] The present invention proposes a laser processing system, which includes the conveying device 100 described in any one of the above items and the laser processing equipment 300 described in the above items, and the conveying device 100 is used to convey the material to be processed.

[0147] In this embodiment, the conveying device 100 can be implemented by a conveyor belt, a roller conveyor, a chain conveyor, a roller, a smooth strip, etc. The laser processing equipment 300 can adopt the above-mentioned laser processing method and automatically generate a processing file to control the processing head 10 (laser head) to process the target material to be processed. At the same time, after the laser processing equipment 300 recognizes that the target material to be processed that does not exist in the image matching the reference processing material or the target material to be processed corresponding to the processing format is processed, it controls the conveying device 100 to move a preset distance and convey the material to be processed to the processing format, so that the laser processing equipment 300 controls the camera 20 to shoot.

[0148] The arrangement of the conveying device 100 can continuously convey the material to be processed to the processing area of ​​the laser processing equipment 300, thereby realizing an uninterrupted processing flow, thereby reducing the time for manual intervention and improving the processing efficiency of the entire production line.

[0149] It is worth noting that since the laser processing system of the present invention is based on the above-mentioned laser processing equipment 300, the embodiments of the laser processing system of the present invention include all technical solutions of all embodiments of the above-mentioned laser processing equipment 300, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0150] The present invention proposes a laser processing system, referring to Fig.11 ,include:

[0151] Laser processing equipment 300;
