[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0050] In the description of the present application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. In the present application, " / " means "or".

[0051] The present application may repeat reference numerals and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0052] In the embodiment of the present invention, in the industrial production process, it is necessary to engrave characters or other graphics on the surface of metal plates, and it is necessary to reach a certain depth, usually requiring a depth greater than 0.3 mm. For example, in the automobile manufacturing industry, it is necessary to engrave a VIN code on a car frame, where the VIN code is a string of 17 characters that can trace the relevant information of the automobile production.

[0053] Common engraving methods include pneumatic engraving and laser engraving. For pneumatic engraving, pneumatic needle engraving is the most widely used engraving method, but this engraving method has the problem of rapid wear of the engraving needle, so the engraving needle needs to be replaced frequently, resulting in low engraving efficiency. Therefore, this engraving method cannot be used for a long time to process high-strength steel. For laser engraving, the engraving efficiency of laser engraved characters is not high enough, and the edges of the engraved characters have many remelting protrusions, resulting in poor engraving effect, which affects the subsequent rubbing effect.

[0054] Therefore, how to improve the engraving efficiency and engraving effect of metal surfaces has become a technical problem that needs to be solved urgently.

[0055] In order to solve the above technical problems, the present application embodiment provides a metal surface engraving method. For details, see Figure 1 , Figure 1 FIG. 1 is a flow chart of a metal surface engraving method provided by an embodiment of the present invention. Figure 1As shown, the metal surface engraving method provided in this embodiment includes steps 101 to 104;

[0056] Step 101: Acquire material information of a material to be engraved, and determine a position to be engraved on the material to be engraved.

[0057] In this embodiment, the material to be engraved provided in this embodiment is a metal plate material to be engraved. The material information provided in this embodiment may include the metal type of the metal plate material and the thickness of the metal plate material. The metal type of the metal plate material may include metal types such as steel, iron, copper, etc.

[0058] The position to be engraved provided in this embodiment is the position of the engraving content to be formed on the material to be engraved, wherein the engraving content formed on the material to be engraved can be characters, text or patterns, and any combination of multiple contents.

[0059] In some embodiments, the present embodiment can use image recognition, for example, by using an image acquisition device to acquire a material image of the material to be engraved, and recognize the material image to determine the material information of the material to be engraved. Specifically, the step of acquiring the material information of the material to be engraved can be: acquiring the material image of the material to be engraved; recognizing the material image to identify the material type information and material thickness information of the material to be engraved.

[0060] In this embodiment, the material image of the material to be engraved can be identified by using a trained material image recognition model, which can be trained by a convolutional neural network CNN and material images containing a variety of different material types. In this way, the material information of the material to be engraved can be obtained in real time by using the trained material image recognition model, thereby effectively improving the efficiency of image recognition and the overall engraving efficiency.

[0061] Step 102: Determine a target engraving strategy for engraving the material to be engraved based on the material information and the position to be engraved.

[0062] After determining the material information and the position to be engraved of the material to be engraved, this embodiment can choose to use mechanical engraving or laser engraving to engrave the material to be engraved. In this embodiment, this embodiment mainly uses laser engraving to engrave the material to be engraved. For details, please refer to Figure 2 , Figure 2 FIG. 1 is a flow chart of determining a target engraving strategy provided by an embodiment of the present invention. Figure 2 As shown, the method for determining a target engraving strategy provided in this embodiment includes steps 201 to 203;

[0063] Step 201: Determine the laser path control parameters of the adopted laser according to the position to be engraved.

[0064] In this embodiment, the laser path control parameters provided in this embodiment are mainly used to control the laser path of the laser emitted by the laser. Since this embodiment mainly uses a laser for engraving, after determining the position to be engraved, it is necessary to adjust the laser path of the laser so that the laser emitted by the laser can be focused on the position to be engraved. Specifically, the laser provided in this embodiment may include a laser transmitter, a beam expander, a scanning galvanometer and a focusing lens. Among them, the laser transmitter is mainly used to provide laser and emit the laser to the beam expander, the beam expander is used to expand the laser and reduce the divergence angle of the laser, the scanning galvanometer is used to deflect the exit angle of the laser emitted through the beam expander, and the focusing lens is used to focus the laser after deflection through the scanning galvanometer onto the material to be engraved, so as to form engraving content at the position to be engraved.

[0065] It should be noted that there may be one or more positions to be engraved on the material to be engraved. After determining that there are multiple positions to be engraved on the material to be engraved, it is necessary to adjust the laser path control parameters in real time according to the engraving content after each engraving at a position to be engraved is completed, so as to control the laser to engrave the next position to be engraved according to the adjusted laser path control parameters.

[0066] Optionally, this embodiment can first obtain an engraving content image of the engraving content that needs to be formed on the material to be engraved, and then pair the engraving content image with the surface of the material to be engraved, so as to map and bind each engraving point in the content image to be engraved to a specific position on the surface of the material to be engraved, so that the engraving material can be accurately engraved according to the engraving content image through the mapping and binding relationship.

[0067] Step 202: Determine the operating parameters of the laser and the target spot overlap rate corresponding to the laser light emitted by the laser according to the material type information and the material thickness information.

[0068] In the related art, the serious problem of edge remelting at the engraving position is often caused by improper laser selection or improper parameter setting. Therefore, this embodiment can use a laser beam with a larger single pulse energy to remove as much material as possible at a single pulse point, while matching a smaller repetition frequency to minimize heat accumulation, thereby effectively reducing the remelted material formed on the material surface, thereby improving engraving efficiency and engraving effect.

[0069] The working parameters provided in this embodiment may include parameters for controlling the working power of the laser and parameters for controlling the working time of the laser, and may also include parameters for controlling the pulse width, laser wavelength, laser head scanning speed, laser frequency, etc., as long as they are parameters related to the laser that affect the engraving process. Specifically, the target spot overlap rate provided in this embodiment can be set by adjusting the laser frequency parameter and scanning speed parameter of the laser.

[0070] Optionally, this embodiment can preset the materials to be engraved according to different type information and material thickness information, as well as the engraving experience gained by the staff through multiple engraving tests, and set a comparison table of "laser working parameters and target spot overlap rate" and "material type information and material thickness information of the material to be engraved". The laser working parameters and target spot overlap rate are selected according to the comparison table. This can ensure that under the selected working parameters and target spot overlap rate, high-efficiency engraving can be achieved while avoiding heat accumulation during the engraving process, thereby effectively reducing the remelted material formed on the material surface, thereby improving the engraving efficiency and engraving effect.

[0071] Step 203: Using the laser path control parameters, the working parameters and the target light spot overlap rate as a target engraving strategy for engraving the material to be engraved.

[0072] After determining the laser path control parameters, the working parameters and the target spot overlap rate, these parameters can be used as a target engraving strategy for engraving the material to be engraved, so that when the material to be engraved is subsequently engraved, the material to be engraved can be engraved using the target engraving strategy, thereby reducing the formation of remelted material on the material surface and improving engraving efficiency and engraving effect.

[0073] Step 103: performing dust removal on the material to be engraved according to the material information and the position to be engraved.

[0074] In order to completely remove the remelted material and avoid edge remelting at the engraving location, which would result in the need for repeated engraving, the present embodiment can quickly peel off and remove the dust generated during the engraving process, thereby preventing remelted material from forming on the material surface. This achieves the purpose of completely removing the remelted material and completely avoiding edge remelting at the engraving location.

[0075] By performing dust removal on the material to be engraved before the engraving process, the interference of dust on the material to be engraved on the engraving process can be effectively reduced, and the influence of dust on the engraving effect can be reduced. At the same time, the dust removal process of this embodiment needs to be carried out continuously, that is, the dust removal process is also carried out during the engraving process, so as to ensure that the dust generated by the engraving process is quickly removed and that no remelted material is formed on the surface of the material to be engraved during the engraving process. Among them, this embodiment can use a dust removal device that can perform air blowing for dust removal, and the gas blown can be nitrogen.

[0076] For details, see Figure 3 , Figure 3 is a schematic diagram of a dust removal process provided by an embodiment of the present invention, such as Figure 3 As shown, the dust removal method provided in this embodiment may include steps 301 to 303;

[0077] Step 301, determining the target wind pressure for air blowing and dust removal using dust removal equipment according to the material information.

[0078] In this embodiment, in order to remove the dust generated during the engraving process as much as possible, this embodiment can determine the amount of dust that will be generated during the engraving process of the corresponding material to be engraved based on different material type information and material thickness information, and then select a matching wind pressure for dust removal based on the amount of dust, avoiding the use of too small wind pressure that leads to the inability to completely blow away the dust, and the use of too large wind pressure that wastes electricity resources, thereby effectively saving electricity resources and engraving costs while effectively removing dust.

[0079] Step 302: determining a target position for blowing air on the material to be engraved according to the position to be engraved.

[0080] Since the present embodiment may provide multiple positions to be engraved, it is necessary to re-determine the target position for blowing air on the material to be engraved each time the position to be engraved is adjusted.

[0081] Step 303: Control the dust removal device to blow air to the target position on the material to be engraved at the target wind pressure to complete dust removal processing on the material to be engraved.

[0082] After the target wind pressure and the target position are determined, the dust removal device can be controlled to continuously blow air to the target position on the material to be engraved at the target wind pressure according to the target wind pressure and the target position, so as to complete the dust removal process on the material to be engraved.

[0083] As an optional embodiment, in order to achieve better dust removal effect, completely remove the remelted material, avoid edge remelting at the engraving location, and cause the need for repeated engraving, so as to more effectively improve the engraving efficiency and engraving effect, please refer to Figure 4 , Figure 4 is a schematic diagram of an application scenario of dust removal processing provided by an embodiment of the present invention, such as Figure 4 As shown, in this embodiment, before the step of performing dust removal on the material to be engraved according to the material information and the position to be engraved, a preset protective cover can be used to perform protective treatment on the material to be engraved, and the protective cover includes an air inlet and an air suction port relatively arranged on left and right sides, and an engraving port arranged on the top, the dust removal device is provided at the air inlet, and the dust suction device is provided at the air suction port. The opening size of the engraving port on the protective cover corresponds to the engraving area to be engraved on the material to be engraved, and the engraving port is used for allowing the laser emitted by the laser to irradiate the surface of the material to be engraved.

[0084] By matching the opening size of the engraving port with the actual size of the engraving area, the focusing lens of the laser can be protected to the maximum extent and the splashing material can be isolated. At the same time, air convection is formed in the protective cover, which can facilitate dust collection and further improve the dust removal effect.

[0085] Please continue to see Figure 4 The dust removal equipment provided in this embodiment may include a first air blowing pipe and a second air blowing pipe, the target wind pressure may include a first wind pressure corresponding to the first air blowing pipe and a second wind pressure corresponding to the second air blowing pipe, the target position may include the position to be engraved corresponding to the first air blowing pipe and the position of the air suction port corresponding to the second air blowing pipe, then the step of controlling the dust removal equipment to blow air to the target position on the material to be engraved with the target wind pressure provided in this embodiment may be: controlling the first air blowing pipe of the dust removal equipment to blow air to the position to be engraved on the material to be engraved with the first wind pressure; controlling the second air blowing pipe of the dust removal equipment to blow air to the position of the air suction port on the material to be engraved with the second wind pressure.

[0086] Among them, by aiming the first air blowing pipe provided in this embodiment at the position to be engraved for blowing, not only can it be ensured that the surface of the material to be engraved will not be oxidized and blackened during the engraving process, making material removal more efficient, but also can play a role in reducing the surface temperature of the material; by aiming the second air blowing pipe provided in this embodiment for blowing at the position of the suction port, the flying sparks can be quickly blown to the dust collection equipment, thereby reducing the pollution to the focusing lens.

[0087] Specifically, the first wind pressure provided in this embodiment can be 0.8-1MPa, and the second wind pressure can be 1.2-1.5MPa. It should be noted that the first wind pressure and the second wind pressure provided in this embodiment can also be set according to the amount of dust to avoid using too small wind pressure to cause the dust to be completely blown away, and using too large wind pressure to waste power resources, so as to effectively save power resources and engraving costs while effectively removing dust.

[0088] Step 104 : in the process of performing dust removal on the material to be engraved, performing engraving on the material to be engraved according to the target engraving strategy.

[0089] In order to completely remove the remelted material and completely avoid edge remelting at the engraving position, this embodiment needs to perform engraving on the material to be engraved according to the target engraving strategy during the dust removal process of the material to be engraved. Specifically, the step of engraving the material to be engraved according to the target engraving strategy provided in this embodiment can be: according to the laser path control parameters, adjust the path of the laser emitted by the laser so that the laser is focused on the position to be engraved on the material to be engraved; according to the working parameters, adjust the working power and working time of the laser; according to the target spot overlap rate, adjust the laser frequency and scanning speed of the laser so that the spot overlap rate of the laser reaches the target laser overlap rate, and the target laser overlap rate is 60%-80%; perform engraving on the material to be engraved.

[0090] By engraving the material to be engraved in the manner provided by the embodiment of the present invention, it is not only possible to quickly form the engraving content at the position to be engraved, but also to avoid the formation of remelted material at the engraving position. After the metal surface engraving method provided by this embodiment is completed at the current position to be engraved, the next unengraved engraving pixel point can be determined according to the engraving content image, and the corresponding position to be engraved can be found on the surface of the material to be engraved according to the pre-set mapping binding relationship, and the metal surface engraving method provided by the embodiment of the present invention is continued to be used to engrave the position to be engraved. This embodiment is executed in a loop until the desired engraving content image is formed on the surface of the material to be engraved, and the engraved material after engraving can be obtained.

[0091] In summary, an embodiment of the present invention provides a metal surface engraving method, including obtaining material information of a material to be engraved, and determining a position to be engraved on the material to be engraved, determining a target engraving strategy for engraving the material to be engraved based on the material information and the position to be engraved, performing dust removal on the material to be engraved according to the material information and the position to be engraved, and performing engraving on the material to be engraved according to the target engraving strategy during the dust removal process of the material to be engraved. By using the embodiment of the present invention, remelted materials can be completely removed during the engraving process, avoiding edge remelting at the engraving position, which results in the need for repeated engraving, thereby improving engraving efficiency and engraving effect.
