[0051] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0052] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0053] The main solution of the embodiment of the present application is: compensating the second parameter of the target point based on the pre-obtained first parameter of the target point; marking the target point based on the first parameter of the target point and the compensated second parameter of the target point.

[0054] In this embodiment, for the convenience of description, the following description is made with the marking system as the execution subject.

[0055] In the prior art, the height difference of the marked object will affect the laser marking effect. Specifically, during the laser marking process, the height difference of the material surface will directly affect the focusing effect of the laser beam. When the material surface is uneven or there is a height difference, the focus point of the laser beam will shift, resulting in uneven distribution of laser energy on the material surface. This uneven energy distribution will directly affect the marking effect, especially the difference in color depth.

[0056] The present application provides a solution, which compensates the second parameter of the target point based on the first parameter of the target point obtained in advance, thereby overcoming the influence of the height difference of the marked object on the marking effect.

[0057] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a marking device, etc. that can realize the above functions, or an electronic system, a marking system, etc. that can realize the above functions. The following takes the marking system as an example to illustrate this embodiment and the following embodiments.

[0058] Based on this, the present application embodiment provides a marking method, referring to Figure 1 , Figure 1 A schematic diagram of the process flow provided for the first embodiment of the marking method of the present application.

[0059] In this embodiment, the marking method includes steps S20 to S30:

[0060] Step S20, compensating the second parameter of the target point based on the first parameter of the target point obtained in advance;

[0061] It should be noted that the marking method of the present application uses a laser generator to generate a high-energy continuous laser beam. The focused laser acts on the surface of the material, causing the local temperature to rise sharply, resulting in instant melting or even vaporization of the material surface. By precisely controlling the path of the laser on the material surface, the desired graphic mark can be formed.

[0062] Reference Figure 2 , Figure 2 A brief flowchart of the marking method for this application is shown below.

[0063] like Figure 2 As shown, the process of the marking method of the present application includes manual loading, turntable rotation, jacking positioning, 3D camera measurement, CCD camera positioning, laser marking, turntable rotation, and manual unloading. The above processes are explained below:

[0064] (1) Manual loading: In this step, the operator manually places the object to be marked at the designated location on the production line. This is usually done on a turntable or conveyor belt to facilitate subsequent automated processing.

[0065] (2) Turntable rotation: After the object is placed, the turntable starts to rotate, transferring the object from one workstation to the next. The design of the turntable allows multiple objects to undergo different processing steps at different workstations at the same time, thereby improving production efficiency.

[0066] (3) Lifting and positioning: When the object is transported to the measuring or marking position, the lifting mechanism will gently lift the object from the turntable and accurately position it. This step is to ensure that the object remains stable during the marking or measurement process to avoid errors caused by position deviation.

[0067] (4) 3D camera measurement: After lifting and positioning, the 3D camera scans the object to obtain the three-dimensional shape and height information of its surface. This information is crucial for subsequent laser marking, because the position of the laser focus needs to be adjusted according to the height of the object surface to ensure the consistency and clarity of the marking effect. Figure 3 , Figure 3 Schematic diagram of the marking process for this application Figure 1 .

[0068] (5) CCD camera positioning: After obtaining the three-dimensional information of the object, the CCD camera takes a picture of the object to obtain its two-dimensional image information. This step is usually used to further accurately determine the marking position to ensure that the marking pattern or text can be accurately placed at the predetermined position on the surface of the object.

[0069] (6) Laser marking: After determining the marking position and adjusting the laser focus, the laser marking equipment begins to mark the object. The laser beam moves on the surface of the object according to the predetermined pattern or text track, forming the required mark by melting or vaporizing the material surface.

[0070] (7) Turntable rotation: After marking is completed, the turntable rotates again to transfer the marked object to the next workstation or output location.

[0071] (8) Manual unloading: Finally, the operator manually removes the marked object at the designated output location, completing the entire marking process. Figure 4 , Figure 4 Schematic diagram of the marking process for this application Figure 2 .

[0072] Reference Figure 5 , Figure 5 This is a schematic diagram of the structure of the marking device of the present application. The marking device of the present application includes a turntable lifting assembly 21, a fixture assembly 22, a light source support assembly 23, a lifting and cavity assembly 25, and a CCD / 3D camera assembly 24. Figure 6 to Figure 10 , Figure 6 The schematic diagram of the turntable lifting assembly is shown in Figure 1. Figure 7 is a schematic diagram of the fixture assembly. Figure 8 is a schematic diagram of the light source support assembly. Fig. 9 It is a schematic diagram of the lifting and cavity components. Fig.10 Schematic diagram of the CCD / 3D camera assembly.

[0073] It should be noted that the target point is the marking point.

[0074] As an implementation manner, the first parameter of the target point may be the X-axis coordinate of the target point, and the second parameter of the target point may be the Z-axis coordinate of the target point.

[0075] As another implementation, the first parameter of the target point may be the height information of the target point, and the second parameter of the target point may be a parameter directly related to laser marking, such as the focus position of the laser beam, laser power, etc.

[0076] Step S30: marking the target point based on the first parameter of the target point and the compensated second parameter of the target point.

[0077] The specific position of the target point can be obtained based on the first parameter of the target point and the compensated second parameter of the target point, so as to mark the target point.

[0078] This embodiment provides a marking method, which compensates the second parameter of the target point based on the first parameter of the target point obtained in advance, thereby overcoming the influence of the height difference of the marked object on the marking effect.

[0079] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be repeated hereafter. On this basis, before step S20, the marking method further includes step S10:

[0080] Step S10: Scan the target point by a 3D measuring instrument to obtain a first parameter and a second parameter of the target point.

[0081] Reference Fig.11 , Fig.11 This is a schematic diagram of scanning a target object by a 3D measuring instrument in the present application, so as to obtain parameters of each target point in the target object, including a first parameter and a second parameter.

[0082] Reference Fig.12 , Fig.12 This is a schematic diagram of the result of scanning a target object using a 3D measuring instrument in this application.

[0083] Depend on Fig.12 It can be seen that the scanning result can accurately reflect the height of the target object.

[0084] Specifically, as an implementation method, the data of product surface protrusions and depressions can be obtained through a 3D laser measuring instrument to generate 3D coordinates, and these 3D coordinates can be compensated in the Z direction through software so that the marking position is always at the laser focus.

[0085] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the first embodiment can refer to the above description, and will not be repeated in the following. On this basis, the first parameter of the target point is the X-axis coordinate of the target point, and the second parameter of the target point is the Z-axis coordinate of the target point. Step S20, based on the first parameter of the target point obtained in advance, compensates the second parameter of the target point and also includes steps S21 to S22:

[0086] Step S21, calculating a corresponding Z-axis compensation value of the target point based on the X-axis coordinate of the target point and the Z-axis coordinate of the target point;

[0087] The step S21 further includes steps S211 to S212:

[0088] Step S211, obtaining a preset Z-axis coordinate based on the X-axis coordinate of the target point;

[0089] It should be noted that in the marking system, the ideal height of the product can be pre-stored.

[0090] Furthermore, the product contour height is scanned through 3D line scanning, and the actual height of the product is compared with the ideal height pre-stored in the software to obtain the height difference between the two. Then, height compensation can be performed based on the height difference.

[0091] Step S212, calculating the corresponding target point Z-axis compensation value based on the preset Z-axis coordinate and the target point Z-axis coordinate.

[0092] Step S22, compensating the Z-axis coordinate of the target point based on the Z-axis compensation value of the target point.

[0093] The compensation value may be added to the current Z-axis coordinate of the target point, and the target point may be subsequently marked based on the X-axis coordinate of the target point and the compensated Z-axis coordinate of the target point.

[0094] Among them, if the actual height of the target point is lower than the ideal height, the compensation value is positive, indicating that the focal position of the laser or the position of the laser beam in the Z-axis direction needs to be adjusted upward; conversely, if the actual height of the target point is higher than the ideal height, the compensation value is negative, which means that the focal position of the laser or the position of the laser beam in the Z-axis direction needs to be adjusted downward when applied.

[0095] Reference Fig.13 , Fig.14 , Fig.13 Schematic diagram of height compensation for this application Figure 1 , Fig.14 Schematic diagram of height compensation for this application Figure 2 ;

[0096] like Fig.13 , Fig.14 As shown, the marking system includes a 3D camera (3D measuring instrument), a reflective lens and a material, wherein the laser mirror and the reflective mirror can be slightly adjusted up and down by a micro-displacement adjustment device to adjust the focal position of the laser or the position of the laser beam, thereby compensating for height changes.

[0097] As an implementation method, the product can be scanned by a 3D camera, and the obtained X-axis and Z-axis coordinates can be provided to the software. After the software obtains the data, it will compensate the Z-axis coordinate at the corresponding X-axis coordinate position during marking, so that the focus is always at the same height on the product.

[0098] Based on the first embodiment of the present application, in the fourth embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be repeated in the following. On this basis, step S30, marking the target point based on the first parameter of the target point and the compensated second parameter of the target point also includes steps S31 and S34:

[0099] Step S31, based on the first parameter of the target point and the compensated second parameter of the target point, controlling the focus adjustment mechanism of the marking device to adjust the focus position;

[0100] As an implementation manner, the focus adjustment mechanism can adjust the focus position by adjusting the positions of the laser mirror and the reflective mirror.

[0101] Step S34, marking the target point based on the adjusted focus position.

[0102] Among them, since the focus position has been corrected according to the actual height of the product, the laser beam can accurately hit the target point and form the desired mark on its surface.

[0103] Based on the fourth embodiment of the present application, in the fifth embodiment of the present application, the same or similar contents as those in the fourth embodiment can be referred to the above description, and will not be repeated in the following. On this basis, before step S34, the marking method further includes steps S32 to S33:

[0104] Step S32, performing a marking test on the target point based on the adjusted focus position to obtain test data;

[0105] It should be noted that in the laser marking process, it is crucial to ensure the accuracy of the focus position, because it directly affects the quality, clarity and consistency of the marking. Even after the focus adjustment mechanism is corrected, the actual focus position may deviate from the expected one due to various factors (such as mechanical errors, changes in material properties, environmental factors, etc.). Therefore, before performing the formal marking operation, you can perform a marking test and check whether the test data meets the expected results.

[0106] Among them, the test data may include sparks, sounds during the marking process, and traces after marking.

[0107] The traces after marking can also include the depth, width, shape, etc. These parameters reflect the quality of the marking effect.

[0108] Step S33, checking whether the test data meets the expected effect.

[0109] Among other things, the test data can be compared with pre-set quality standards, design specifications or previously marked samples.

[0110] Based on the fifth embodiment of the present application, in the sixth embodiment of the present application, the same or similar contents as those in the fifth embodiment can be referred to the above description, and will not be repeated in the following. On this basis, step S33, checking whether the test data meets the expected effect also includes step S331:

[0111] Step S331, using a preset AI model to check at least one of the sparks, sounds, and marks after marking during the marking process to determine whether they meet the expected effect.

[0112] It should be noted that the AI ​​model used is obtained through training. The training process is described in the following 6 points:

[0113] 1. Data collection: Collect relevant data such as sparks, sounds, and traces after marking generated during the marking process. These data should cover the marking process under various circumstances, including normal and abnormal situations, to ensure the generalization ability of the model.

[0114] 2. Data preprocessing: Preprocess the data according to the characteristics of the collected data.

[0115] 3. Model selection: Select the appropriate AI model according to the characteristics of the marking process and the inspection requirements. For example, for sound inspection, you can choose a convolutional neural network (CNN) or a recurrent neural network (RNN) in deep learning; for image inspection, such as traces after marking, you can choose a convolutional neural network in deep learning. In summary, you can choose a convolutional neural network in deep learning as the AI ​​model.

[0116] 4. Model design: Based on the selected model, build the architecture of the AI ​​model, including determining the model's hierarchy, activation function, loss function and other key parameters. Design algorithms and processes suitable for marking process inspection to ensure that the model can accurately identify and judge features such as sparks, sounds, and post-marking traces.

[0117] 5. Model training: Use the preprocessed data set to train the AI ​​model. During the training process, the model will continuously learn the characteristics and rules of the data and adjust the model parameters to minimize the loss function.

[0118] 6. You can also perform model evaluation and testing to further optimize the model.

[0119] Subsequently, the AI ​​model can be deployed and applied.

[0120] Among them, the trained AI model is deployed to the marking equipment or system and integrated with the marking process to ensure that the model can check sparks, sounds, post-marking traces and other features in real time and accurately in actual applications.

[0121] During the marking process, the AI ​​model will automatically check features such as sparks, sounds, and marks after marking, and give a judgment on whether it meets the expected effect. Based on the judgment results of the AI ​​model, the marking equipment or system can automatically adjust the marking parameters or issue an alarm to ensure the quality and safety of the marking process.
