[0050] Description of main component symbols:

[0051] Graphite boat 100, main body 10, connecting part 12, boat foot 14, three-dimensional identification part 20, substrate 22, three-dimensional identification part 24, side wall 26, protruding distance A of side wall 26, protruding distance B of three-dimensional identification part 24, depth C of three-dimensional identification part 24, and distance D between two adjacent three-dimensional identification parts 24. Specific embodiments

[0052] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0053] In the prior art, the process of setting an identification code for a target object requires a lot of manual intervention, which is inefficient and prone to errors. The present application provides a production method and production system, which generates a dot matrix production file based on a two-dimensional code and a dot matrix template image, and controls a production machine to produce a three-dimensional identification part on the target object according to the dot matrix production file. This allows the entire process from the generation of the production file to the production of the three-dimensional identification part to be automated, avoiding excessive manual intervention and facilitating the efficient and accurate setting of identification on the target object.

[0054] See also Figure 1 The manufacturing method provided in the embodiment of the present application is used to manufacture a three-dimensional marking portion on a target object, and the manufacturing method includes:

[0055] Step S12: Obtain identification information of the target object;

[0056] Step S14: Generate a QR code based on the identification information;

[0057] Step S16: generating a dot matrix production file according to the QR code and the pre-stored dot matrix template image;

[0058] Step S18: Control the production machine to produce a three-dimensional marking portion on the target object according to the dot matrix production file.

[0059] In the production method of the embodiment of the present application, a dot matrix production file is generated based on a QR code and a dot matrix template image, and a production machine is controlled to produce a three-dimensional identification part on the target object according to the dot matrix production file, so that everything from the generation of the production file to the production of the three-dimensional identification part can be automated, avoiding excessive manual participation, and facilitating the efficient and accurate setting of identification on the target object.

[0060] Specifically, in this embodiment, the target object comprises a graphite boat. In other embodiments, the target object includes, but is not limited to, a quartz vessel, a carbon fiber plate, and other objects. For ease of explanation, the following explanation and description uses a graphite boat as an example, but this does not limit the specific form of the target object.

[0061] Specifically, in this embodiment, the identification information includes the target object's number. Each target object is assigned a number that distinguishes one target object from another. The target object's number can consist of at least one of numbers, letters, symbols, and text. The target object's number can be a string of one, two, three, four, or other digits. The specific format of the number is not limited herein.

[0062] In other embodiments, the identification information may further include at least one of the name, size, material, etc. of the target object. The specific content of the identification information is not limited herein.

[0063] Specifically, in step S14, a QR code generation plug-in can be used to generate a QR code based on the identification information. The QR code generation plug-in includes Python's QRCode. In this way, a QR code can be generated based on the identification information in a simple and convenient manner.

[0064] See also Figure 2 Optionally, step S16 includes:

[0065] Step S162: Generate a coordinate list based on the QR code and the dot matrix template image;

[0066] Step S164: Generate a dot matrix production file according to the coordinate list.

[0067] In this way, the dot matrix production file is generated based on the QR code and the pre-stored dot matrix template, which is simple, convenient and efficient. Moreover, since the dot matrix production file is generated based on the coordinate list, it is more accurate, which is conducive to more precise production of the three-dimensional logo part.

[0068] Specifically, in step S162, the two-dimensional code may be a QR Code, a Maxi Code, or a DataMatrix Code, and the specific form of the two-dimensional code is not limited here.

[0069] A coordinate list includes one or more coordinates. In other words, a coordinate list is a list of one or more coordinates. The coordinates here can be two-dimensional or three-dimensional. The specific form of the coordinates is not limited here.

[0070] Specifically, in step S164, the dot matrix production file is a file that can be recognized by the production machine, such as a CAD file.

[0071] Furthermore, Python's DXFWriter can be used to generate a DXF dot matrix production file based on the coordinate list. Since DXF files can be directly imported into most engraving machines, the engraving machine can carve the 3D logo part based on the coordinate points in the DXF dot matrix production file, avoiding the situation where the dot matrix production file cannot be recognized and used by the production machine.

[0072] See also Figure 3 Optionally, step S162 includes:

[0073] Step S1622: determining the target pixel of the QR code according to the QR code and the dot matrix template image;

[0074] Step S1624: Generate a coordinate list according to the coordinates of the target pixel.

[0075] In this way, a coordinate list is generated based on the QR code and the dot matrix template. Moreover, the coordinate list is a list of target pixels, which avoids interference from non-target pixels on the coordinate list and helps ensure the accuracy of the dot matrix production file.

[0076] Specifically, in step S1624, after all target pixels are determined, a coordinate list is generated based on all target pixels. In this way, the coordinate list is generated once, which is more efficient.

[0077] In step S1624, each time a target pixel is determined, the coordinate list is updated according to the target pixel. In this way, if the method is interrupted for some reason, some data can be retained so that the method can be continued after the fault is eliminated.

[0078] Optionally, step S1622 includes:

[0079] Compare each pixel of the QR code with the corresponding pixel of the dot matrix template image;

[0080] When the current pixel of the two-dimensional code and the corresponding pixel of the dot matrix template image are both preset colors, the current pixel is used as the target pixel.

[0081] In this way, by comparing the colors of pixels at corresponding positions, the target pixel of the QR code can be determined based on the QR code and the dot matrix template image, without the need for complex calculations and with high efficiency.

[0082] Specifically, in this embodiment, the phrase "each pixel of the QR code corresponds to a corresponding pixel of the dot matrix template image" means that the pixel coordinates are the same. For example, the pixel with coordinates (1,1) in the QR code corresponds to the pixel with coordinates (1,1) in the dot matrix template image; and for another example, the pixel with coordinates (1,2) in the QR code corresponds to the pixel with coordinates (1,2) in the dot matrix template image.

[0083] It can be understood that in other embodiments, the "correspondence" in "each pixel of the QR code and the corresponding pixel of the dot matrix template image" may refer to the coordinates of the pixels of the QR code and the coordinates of the pixels of the dot matrix template image satisfying other preset functional relationships.

[0084] For example, the horizontal coordinate of a pixel in the dot matrix template is twice the horizontal coordinate of a pixel in the QR code, and the vertical coordinate of a pixel in the dot matrix template is twice the vertical coordinate of a pixel in the QR code. That is, the pixel with coordinates (1,1) in the QR code corresponds to the pixel with coordinates (2,2) in the dot matrix template; and the pixel with coordinates (1,2) in the QR code corresponds to the pixel with coordinates (2,4) in the dot matrix template.

[0085] The specific correspondence between the pixels of the QR code and the dot matrix template image is not limited here.

[0086] Specifically, in this embodiment, the preset color is black. It is understood that in other embodiments, the preset color may also be white or other colors. The specific color type of the preset color is not limited here.

[0087] In one example, the target pixel of a QR code is determined based on QR code P1 and dot matrix template image P2. The pixel at coordinates (3,3) in QR code P1 is black, while the pixel at coordinates (3,3) in dot matrix template image P2 is white. Since the two colors are different, the pixel at coordinates (3,3) in QR code P1 is not the target pixel. The pixel at coordinates (3,4) in QR code P1 is white, while the pixel at coordinates (3,4) in dot matrix template image P2 is white. Since both colors are the same and white, they are not the preset color. Therefore, the pixel at coordinates (3,4) in QR code P1 is not the target pixel. The pixel at coordinates (3,5) in QR code P1 is black, while the pixel at coordinates (3,5) in dot matrix template image P2 is black. Since both colors are the same and black, they are the preset color. Therefore, the pixel at coordinates (3,5) in QR code P1 is the target pixel. Therefore, the pixel at coordinates (3,5) is added to the coordinate list. The aforementioned comparison process is performed on each pixel in the two-dimensional code P1 to obtain a final coordinate list.

[0088] Optionally, see Figure 4 After generating a coordinate list based on the QR code P1 and the dot matrix template image P2, the dotted QR code image P3 can be drawn based on the coordinate list. This allows the user to intuitively perceive the shape of the 3D identification portion. It can be understood that the projection of the 3D identification portion along the height direction is consistent with the dotted QR code image P3.

[0089] Specifically, a Python plug-in such as OPenCV or DXFWriter can be used to generate the dot-shaped QR code image P3 according to the coordinate list. The specific method of generating the dot-shaped QR code image P3 according to the coordinate list is not limited here.

[0090] See also Figure 5 Optionally, the target object includes a marking area, and the manufacturing machine includes a precision engraving machine. Step S18 includes:

[0091] Step S182: Control the engraving machine to carve a three-dimensional logo portion in the logo area according to the dot matrix production file.

[0092] In this way, the three-dimensional logo part is directly engraved on the logo area of ​​the target object by a precision engraving machine. The production process is relatively simple, the production efficiency is high, and it is easy to control the details of the three-dimensional logo part, so that the three-dimensional logo part fits the dot matrix production file.

[0093] It is understood that in other embodiments, the engraving machine can be controlled to engrave a three-dimensional marking portion on the substrate according to the dot matrix production file and then position the three-dimensional marking portion in the marking area of ​​the target object. In this way, the engraved object is smaller in size, making it easier for the engraving machine to perform engraving. Furthermore, if an engraving error occurs, the substrate can be replaced and the engraving can be repeated, preventing damage to the target object caused by the engraving error.

[0094] It is understood that in other embodiments, the three-dimensional logo portion may be generated using an injection molding process according to the dot matrix production file. In other embodiments, the three-dimensional logo portion may be generated using a laser engraving process according to the dot matrix production file. In still other embodiments, multiple three-dimensional identification components may be fixed to a substrate according to the dot matrix production file to form the three-dimensional logo portion. The specific process for generating the three-dimensional logo portion is not limited herein.

[0095] See also Figure 6 Optionally, the three-dimensional identification portion includes a substrate and a plurality of three-dimensional identification members provided on the substrate, each of the three-dimensional identification members protruding outward from the substrate; step S182 includes:

[0096] Step S1822: Control the engraving machine to determine the first area and the second area of ​​the substrate located in the marking area according to the dot matrix production file; wherein the first area is the spatial area corresponding to the substrate and each three-dimensional marking element, and the second area is the spatial area of ​​the substrate excluding the first area;

[0097] Step S1824: Control the engraving machine to remove the portion of the substrate in the second area to engrave a three-dimensional marking portion.

[0098] In this way, by controlling the engraving machine to remove the portion of the base except the three-dimensional identification portion, the three-dimensional identification part protruding outward from the base plate is engraved from the base. It can be understood that since only a portion of the base needs to be removed and no material needs to be added, the production speed is faster and the efficiency is higher.

[0099] See also Figure 7 In one example, a substrate 200 is provided, and then the engraving machine is controlled to remove the portion 30 of the substrate 200 in the second region, thereby obtaining the portion of the substrate 200 in the first region, i.e., the three-dimensional identification portion 20. The three-dimensional identification portion 20 includes a substrate 22 and a three-dimensional identification member 24 protruding outward from the substrate 22.

[0100] See also Figure 8 Optionally, the three-dimensional identification portion includes a substrate and a plurality of three-dimensional identification members provided on the substrate, each of the three-dimensional identification members being recessed inward from the substrate; step S182 includes:

[0101] Step S1826: Control the engraving machine to determine the third area and the fourth area of ​​the substrate located in the marking area according to the dot matrix production file; wherein the third area is the spatial area corresponding to each three-dimensional marking component, and the fourth area is the spatial area of ​​the substrate excluding the third area;

[0102] Step S1828: Control the engraving machine to remove the portion of the substrate in the third area to engrave a three-dimensional marking portion.

[0103] In this way, by controlling the engraving machine to remove the portion of the base corresponding to the three-dimensional identification member, a three-dimensional identification portion of the three-dimensional identification member that is recessed inward from the base plate is carved out of the base. As can be understood, since only a portion of the base needs to be removed and no material needs to be added, the production speed is faster and more efficient.

[0104] See also Figure 9 In one example, a substrate 200 is provided, and then the engraving machine is controlled to remove the portion 40 of the substrate 200 in the third region, thereby obtaining the portion of the substrate 200 in the fourth region, i.e., the three-dimensional identification portion 20. The three-dimensional identification portion 20 includes a substrate 22 and a three-dimensional identification member 24 recessed inwardly from the substrate 22.

[0105] Optionally, the dot matrix production file includes two-dimensional parameters, the three-dimensional identification portion includes a substrate and a plurality of three-dimensional identification elements provided on the substrate, and step S18 includes:

[0106] Obtaining the depth parameters of the preset three-dimensional identification component;

[0107] The manufacturing machine is controlled to manufacture a three-dimensional marking portion on the target object according to the two-dimensional parameters and the depth parameters.

[0108] In this way, the manufacturing machine can manufacture the three-dimensional marking portion on the target object based on the three-dimensional parameters, thereby making the manufacturing of the three-dimensional marking portion more accurate.

[0109] Specifically, the depth parameter range is greater than 1 mm and less than 4 mm. This ensures that the depth of the three-dimensional identification component is within a reasonable range, avoiding the possibility of the component being covered after multiple coatings due to a too small depth, and also avoiding the possibility of the structural strength of the three-dimensional identification component being poor due to an excessive depth.

[0110] Specifically, the two-dimensional parameters include the spacing between two adjacent three-dimensional identification elements, which ranges from greater than 0.4mm to less than 4mm. This ensures that the spacing between two adjacent three-dimensional identification elements is within a reasonable range, avoiding the difficulties in processing and poor recognizability caused by too small a spacing, and also avoiding the excessive size of the three-dimensional identification element caused by too large a spacing.

[0111] Please note that the explanation and description of the depth parameters and two-dimensional parameters are detailed later in this article and will not be repeated here to avoid redundancy.

[0112] In other examples, the dot matrix production file includes two-dimensional parameters. The depth parameters of a preset three-dimensional identification component can be obtained and the dot matrix production file can be updated based on the depth parameters, so that the dot matrix production file includes both two-dimensional and depth parameters. This allows the production machine to directly produce the three-dimensional identification component on the target object based on the three-dimensional parameters in the dot matrix production file, thereby achieving more accurate production of the three-dimensional identification component. Furthermore, the three-dimensional parameters are all included in the dot matrix production file, facilitating subsequent parameter storage and unified modification.

[0113] See also Figure 10 The production system 100 provided in an embodiment of the present application includes a processor 101 and a memory 102 connected to the processor 101. The memory 102 stores a production program. When the production program is executed by the processor 101, any of the above-mentioned production methods is implemented.

[0114] For example, the following steps are performed: Step S12: obtaining identification information of the target object;

[0115] Step S14: Generate a QR code based on the identification information;

[0116] Step S16: generating a dot matrix production file according to the QR code and the pre-stored dot matrix template image;

[0117] Step S18: Control the production machine to produce a three-dimensional marking portion on the target object according to the dot matrix production file.

[0118] In the production system 100 of the embodiment of the present application, a dot matrix production file is generated based on the QR code and the dot matrix template image, and the production machine is controlled to produce a three-dimensional identification part on the target object according to the dot matrix production file, so that everything from the generation of the production file to the production of the three-dimensional identification part can be automated, avoiding excessive manual participation, and facilitating the efficient and accurate setting of the identification on the target object.

[0119] Please note that for other explanations and descriptions of the production system 100, please refer to the above explanations and descriptions of the production method. To avoid redundancy, they will not be repeated here.

[0120] The above-mentioned manufacturing method can be used to manufacture a three-dimensional marking portion on a target object. The structure of the three-dimensional marking portion is further described below using a graphite boat as an example.

[0121] See also Figure 11 and Figure 12 The graphite boat 100 provided in an embodiment of the present application includes a main body 10 and a three-dimensional identification portion 20 provided on the main body 10. The three-dimensional identification portion 20 includes a substrate 22 and a plurality of three-dimensional identification parts 24 provided on the substrate 22. The orthographic projection of the plurality of three-dimensional identification parts 24 on the substrate 22 forms a two-dimensional code, and each three-dimensional identification part 24 includes a curved surface.

[0122] In the graphite boat 100 of the present embodiment, the orthographic projections of the multiple three-dimensional identification elements 24 onto the substrate 22 form a two-dimensional code, enabling identification of the graphite boat 100 based on the QR code, eliminating the tedious and error-prone manual input. Furthermore, the multiple three-dimensional identification elements 24 enhance the recognizability of the three-dimensional identification portion 20 based on their depth information. Curved three-dimensional identification elements 24 enhance the contrast of the three-dimensional identification portion 20 based on their curvature. This facilitates efficient and accurate identification of the graphite boat 100.

[0123] Understandably, in related art, when PECVD equipment coats silicon wafers carried by graphite boats, the boat's logo is easily coated and discolored, resulting in poor contrast and, consequently, poor legibility, making it unusable. Furthermore, even when creating a deep, three-dimensional logo through grooving, the contrast between the groove's inner wall and the ungrooved edge remains poor at certain angles, resulting in poor recognition.

[0124] In the present application, since the three-dimensional identification part 24 includes a curved surface, after continuous coating, the three-dimensional identification part 24 can present a good contrast even if the color is similar to that of the surrounding objects, thereby making the three-dimensional identification part 20 more recognizable and allowing the three-dimensional identification part 20 to be used sustainably.

[0125] Moreover, in the present application, the three-dimensional identification part 24 has depth. Even if the three-dimensional identification part 24 has a similar color to the surrounding objects, the three-dimensional identification part 24 can be distinguished from the surrounding objects based on the depth information, thereby making the three-dimensional identification part 20 more recognizable.

[0126] Specifically, the number of three-dimensional identification parts 24 can be 1, 2, 3, 5, 15, 23 or other numbers, and the specific number of three-dimensional identification parts 24 is not limited here.

[0127] Please refer again Figure 11 Optionally, the body 10 includes a connecting portion 12 and a plurality of boat legs 14, wherein the plurality of boat legs 14 are connected by the connecting portion 12, and the three-dimensional identification portion 20 is disposed on the outer surface of the connecting portion 12. In this manner, the three-dimensional identification portion 20 is positioned low and does not interfere with the normal operation of the graphite boat 100. Furthermore, the three-dimensional identification portion 20 disposed on the outer surface of the connecting portion 12 facilitates imaging and identification of the three-dimensional identification portion 20.

[0128] Specifically, the connecting portion 12 includes but is not limited to a connecting pipe, a connecting rod or other types of components, and the specific form of the connecting portion 12 is not limited herein.

[0129] Optionally, the graphite boat 100 includes a shifting mechanism, and the three-dimensional identification portion 20 is disposed on the shifting mechanism, which is configured to move under an external force to change the position of the three-dimensional identification portion 20. In this way, the position of the three-dimensional identification portion 20 is changed so as to be photographed and identified.

[0130] Specifically, the shifting mechanism may include a slide rail and a slide groove. The slide rail is provided on the three-dimensional identification portion 20, and the slide groove is formed in the connecting portion 12. Under the action of an external force, the slide rail can move along the slide groove to drive the three-dimensional identification portion 20 to move. In this way, the position of the three-dimensional identification portion 20 on the connecting portion 12 can be changed simply and conveniently.

[0131] Alternatively, the three-dimensional identification portion 20 may include a first connector, and the body 10 may include multiple second connectors in different positions. When the second connectors cooperate with the first connector, the three-dimensional identification portion 20 is fixedly connected to the body 10. In this way, the position of the three-dimensional identification portion 20 on the body 10 can be changed by changing the second connector that cooperates with the first connector, so that it can be captured and recognized by the three-dimensional identification portion 20.

[0132] Specifically, the first connecting member may be one of a screw and a screw hole, and the second connecting member may be the other of the screw and the screw hole. The first connecting member and the second connecting member may be connected by a thread. In other examples, the first connecting member and the second connecting member may be connected by a buckle, Velcro, tape, or other means. This is not limited here.

[0133] See also Figure 13 Optionally, the orthographic projection of the three-dimensional identification member 24 on the substrate 22 is circular. In this way, the orthographic projections of the multiple three-dimensional identification members 24 on the substrate 22 form a dot-shaped two-dimensional code, which is easy to identify and helps to improve the efficiency of identification.

[0134] It is understood that in other examples, the orthographic projection of the three-dimensional identification element 24 on the substrate 22 may be an ellipse, a racetrack, or other shapes, which are not limited here.

[0135] See also Figure 14 、 Figure 15 and Figure 16 Optionally, the three-dimensional identification element 24 is hemispherical. In this way, the spherical surface makes the contrast of the three-dimensional identification element 24 better, which is conducive to improving the recognizability of the three-dimensional identification portion 20.

[0136] It can be understood that in other examples, the three-dimensional identification member 24 can be spherical, ellipsoidal or other shapes, and the specific shape of the three-dimensional identification member 24 is not limited here.

[0137] See also Figure 14Optionally, each three-dimensional identification member 24 protrudes outward from the substrate 22. In this way, a height difference is formed between the three-dimensional identification member 24 and the substrate 22, which is beneficial to improving the recognizability of the three-dimensional identification member 24 based on depth.

[0138] Specifically, the three-dimensional identification component 24 includes a bottom plane and a curved surface. The bottom plane is provided on the substrate 22 , and the curved surface protrudes from the substrate 22 .

[0139] This ensures that the contact surface between the three-dimensional identification element 24 and the substrate is flat, ensuring that the three-dimensional identification element 24 is stably connected to the substrate 22 and will not easily fall off. The curved surface protruding from the substrate 22 gives the three-dimensional identification element 24 good contrast, thus ensuring the three-dimensional identification element 24 is easily identifiable.

[0140] See also Figure 15 Optionally, the three-dimensional identification portion 20 includes a side wall 26 protruding outward from the edge of the substrate 22, the protruding direction of the side wall 26 is the same as the protruding direction of the three-dimensional identification part 24, and the protruding distance A of the side wall 26 is greater than the protruding distance B of the three-dimensional identification part 24.

[0141] In this way, when a foreign object approaches the three-dimensional identification part 24, the side wall 26 can maintain the distance between the three-dimensional identification part 24 and the foreign object, avoiding direct contact between the three-dimensional identification part 24 and being worn by the foreign object, thereby avoiding damage to the curved surface of the three-dimensional identification part 24, which is conducive to ensuring the identifiability of the three-dimensional identification part 24.

[0142] See also Figure 16 Optionally, each three-dimensional identification element 24 is recessed inward from the substrate 22. In this way, a height difference is formed between the three-dimensional identification element 24 and the substrate 22, which is beneficial to improving the recognizability of the three-dimensional identification element 24 based on depth.

[0143] Specifically, the curved surface of the three-dimensional identification member 24 is recessed inward from the surface of the substrate 22. It is understood that because the curved surface of the three-dimensional identification member 24 is lower than the surface of the substrate 22, the surface of the substrate 22 maintains a gap between the curved surface of the three-dimensional identification member 24 and external objects, preventing damage to the curved surface of the three-dimensional identification member 24 and ensuring the recognizability of the three-dimensional identification member 24.

[0144] Moreover, when making the three-dimensional identification portion 20, it is only necessary to dig a hole from the substrate 22 to remove the portion corresponding to the curved surface of the three-dimensional identification member 24. The process is relatively simple and convenient, takes less time, and is more efficient.

[0145] See also Figure 17 Optionally, part of the three-dimensional identification member 24 is recessed from the substrate 22, while the remaining three-dimensional identification member 24 protrudes from the substrate 22. In this way, a height difference is formed between the three-dimensional identification member 24 and the substrate 22, which is conducive to improving the recognizability of the three-dimensional identification member 24 based on the depth.

[0146] For the explanation and description of this part, please refer to the previous Figure 14 and Figure 16 To avoid redundancy, the part will not be repeated here.

[0147] Please refer again Figure 14 and Figure 16 Optionally, the depth C of the three-dimensional identification member 24 is within a range of greater than 1 mm and less than 4 mm. This ensures that the depth of the three-dimensional identification member 24 is within a reasonable range, thereby preventing the three-dimensional identification member 24 from being covered after multiple coatings due to a too small depth, and preventing the three-dimensional identification member 20 from having a poor structural strength due to an excessive depth.

[0148] Please note that in Figure 14 In the example of , the depth C of the three-dimensional identification member 24 is the distance from the highest point of the three-dimensional identification member 24 to the upper surface of the substrate 22. Figure 16 In the example, the depth C of the three-dimensional identification member 24 is the distance from the lowest point of the three-dimensional identification member 24 to the upper surface of the substrate 22.

[0149] exist Figure 14 and Figure 16 In the example of FIG, the depth C of the three-dimensional identification element 24 is 2 mm. In this way, the recognizability of the three-dimensional identification element 24 and the structural strength of the three-dimensional identification portion 20 can be taken into account.

[0150] In another example, the depth C of the three-dimensional marking member 24 is 1 mm; in another example, the depth C of the three-dimensional marking member 24 is 4 mm; in yet another example, the depth C of the three-dimensional marking member 24 is 1.2 mm; in yet another example, the depth C of the three-dimensional marking member 24 is 1.8 mm; in yet another example, the depth C of the three-dimensional marking member 24 is 2.1 mm; in yet another example, the depth C of the three-dimensional marking member 24 is 2.5 mm; in yet another example, the depth C of the three-dimensional marking member 24 is 3.3 mm; in yet another example, the depth C of the three-dimensional marking member 24 is 3.6 mm; and in yet another example, the depth C of the three-dimensional marking member 24 is 3.8 mm. The specific value of the depth C of the three-dimensional marking member 24 is not limited herein.

[0151] Please refer again Figure 13 Optionally, the distance D between two adjacent three-dimensional identification members 24 is in the range of greater than 0.4 mm and less than 4 mm.

[0152] In this way, the distance D between two adjacent three-dimensional identification parts 24 is within a reasonable range, avoiding the difficulty in processing and poor recognizability caused by too small a distance D, and also avoiding the three-dimensional identification part 20 being too large due to too large a distance D.

[0153] Please note that "adjacent" here means that there is no space between the two three-dimensional identification elements 24. In other words, if there is a space between the two three-dimensional identification elements 24, then the two three-dimensional identification elements 24 are not adjacent. For example, Figure 13 In the example, the three-dimensional identification element 24a is not adjacent to the three-dimensional identification element 24b, and the three-dimensional identification element 24b is adjacent to the three-dimensional identification element 24c.

[0154] exist Figure 13 In the example of FIG, the distance D between two adjacent three-dimensional identification elements 24 is 0.86 mm. In this way, the identifiability of the three-dimensional identification element 24 and the reasonable volume of the three-dimensional identification portion 20 can be taken into account.

[0155] In another example, the distance D between two adjacent three-dimensional identification members 24 is 0.4 mm; in another example, the distance D between two adjacent three-dimensional identification members 24 is 0.48 mm; in yet another example, the distance D between two adjacent three-dimensional identification members 24 is 0.72 mm; in yet another example, the distance D between two adjacent three-dimensional identification members 24 is 1.8 mm; in yet another example, the distance D between two adjacent three-dimensional identification members 24 is 2.1 mm; in yet another example, the distance D between two adjacent three-dimensional identification members 24 is 2.4 mm; in yet another example, the distance D between two adjacent three-dimensional identification members 24 is 3.3 mm; in yet another example, the distance D between two adjacent three-dimensional identification members 24 is 3.6 mm; and in yet another example, the distance D between two adjacent three-dimensional identification members 24 is 4 mm. The specific value of the distance D between two adjacent three-dimensional identification members 24 is not limited herein.

[0156] Alternatively, a precision engraving machine can be used to engrave the substrate to obtain the base plate 22 and the three-dimensional identification element 24. The spacing D between two adjacent three-dimensional identification elements 24 can be 1.2-1.8 times the diameter of the cutter head. This allows the cutter head to have a suitable range of motion between two adjacent three-dimensional identification elements 24, avoiding the cutter head being restricted in motion or easily damaging the three-dimensional identification elements 24 due to a small spacing D between two adjacent three-dimensional identification elements 24.

[0157] In the present application, the distance D between two adjacent three-dimensional identification members 24 may be 1.5 times the diameter of the tool head.

[0158] In another example, the distance D between two adjacent three-dimensional identification members 24 may be 1.2 times the diameter of the tool head; in another example, the distance D between two adjacent three-dimensional identification members 24 may be 1.3 times the diameter of the tool head; in yet another example, the distance D between two adjacent three-dimensional identification members 24 may be 1.4 times the diameter of the tool head; in yet another example, the distance D between two adjacent three-dimensional identification members 24 may be 1.6 times the diameter of the tool head; in yet another example, the distance D between two adjacent three-dimensional identification members 24 may be 1.7 times the diameter of the tool head; in yet another example, the distance D between two adjacent three-dimensional identification members 24 may be 1.8 times the diameter of the tool head. The specific quantitative relationship between the distance D between two adjacent three-dimensional identification members 24 and the tool head diameter is not limited herein.

[0159] Specifically, the diameter of the cutter head of the engraving machine can range from 0.4 to 2.0 mm. This allows for a variety of cutter head diameters, allowing selection based on actual production conditions, while also preventing the structural strength of the three-dimensional marking portion 20 from being too poor due to an excessively large cutter head diameter.

[0160] In this application, the diameter of the cutter head of the fine engraving machine is 0.6 mm. In this way, the diameter of the cutter head is suitable for engraving on the substrate.

[0161] In another example, the diameter of the cutter head of the engraving machine is 0.4 mm; in another example, the diameter of the cutter head of the engraving machine is 0.46 mm; in yet another example, the diameter of the cutter head of the engraving machine is 0.5 mm; in yet another example, the diameter of the cutter head of the engraving machine is 0.8 mm; in yet another example, the diameter of the cutter head of the engraving machine is 1.2 mm; in yet another example, the diameter of the cutter head of the engraving machine is 1.7 mm; in yet another example, the diameter of the cutter head of the engraving machine is 2.0 mm. The specific value of the diameter of the cutter head of the engraving machine is not limited here.

[0162] Optionally, the three-dimensional identification portion 20 may also be injection molded. The specific manufacturing method of the three-dimensional identification portion 20 is not limited here.

[0163] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
