其中第一种方式，CNC精雕效率较低，且高速刀具易磨损，需要频繁更换，增加耗材成本；同时，精雕过程可能在壳体表面留下刀纹，影响整体外观
[0015] After adopting the above technical solution, the beneficial effects of this invention are as follows: Compared with traditional CNC precision carving technology, this notebook shell marking stamping forming device has higher processing efficiency, does not require frequent replacement of its own components, and avoids leaving tool marks on the shell that affect its appearance. Compared with existing stamping devices, this notebook shell marking stamping forming device has a raised rib on the side of the second marking component facing the upper mold component, and the raised rib is circumferentially arranged along the edge of the end where the second marking block mates with the first marking block, and the raised rib protrudes towards the upper mold component. This arrangement makes the part of the shell that contacts the raised rib (i.e., the connection between the area where the marking is formed on the shell and the peripheral plane area) fit more closely to the corner structure of the stamping end of the first marking component, thereby forming a distinct, sharp, and clear corner structure at the connection between the area where the marking is formed on the shell and the peripheral plane area. This ensures that the edge of the area where the marking is formed on the shell is a clear and sharp corner structure, avoiding the formation of a rounded corner at the top edge of the marking area on the shell due to the shell's own hardness or thickness during stamping, which would otherwise prevent the shell from fitting the corner structure of the stamping end of the first marking block. This allows for precise stamping of sharp-edged logos, preventing consumer misidentification and ensuring consistent surface gloss and color variation during subsequent surface treatments such as polishing, sandblasting, and anodizing. Furthermore, the raised ribs cause the area where the shell contacts the ribs to be recessed towards the upper mold assembly, thinning the connection between the logo area and the surrounding planar area. During stamping, this connection is more prone to forming sharp corners, resulting in a clear and sharp edge structure when viewed from the front.

Abstract
Description
Technical Field
[0001] This invention relates to the field of notebook casing manufacturing and processing technology, specifically to a notebook casing marking stamping forming device. Background Technology
[0002] A laptop computer is a small, portable personal computer. To enhance brand recognition and influence, a logo is usually placed on the laptop's casing. Logo types include: letter logos, word logos, graphic logos, badge logos, or combinations of these.
[0003] Currently, there are two common methods for machining logos on laptop casings: CNC precision engraving and stamping. The first method, CNC precision engraving, is less efficient, and the high-speed cutting tools wear out easily, requiring frequent replacements and increasing material costs. Furthermore, the engraving process may leave tool marks on the casing surface, affecting the overall appearance. The second method, using existing stamping dies to stamp the logo onto the laptop casing, is more efficient. However, during the stamping process, even if the stamping block and its corresponding components create clear edges and corners for the logo, the casing simultaneously experiences downward tensile and lateral contractile forces, and the material properties of the casing itself (laptop casings are typically made of sheet metal, such as aluminum), the final logo on the casing has rounded edges (i.e., radius corners). This rounded edge structure has the following drawbacks: firstly, the logo outline is blurred and indistinct, making it impossible to achieve precise stamping for some sharp-edged logos, and even potentially causing consumer misidentification. Furthermore, during subsequent surface treatments such as polishing, sandblasting, and anodizing, color differences and inconsistent gloss are prone to occur in this arc (i.e., R-corner) area. Summary of the Invention
[0004] The purpose of this invention is to address the deficiencies and shortcomings of the prior art by providing a notebook shell marking stamping device that can solve at least one of the above-mentioned problems, and has the advantages of high processing efficiency and avoiding the formation of R-angle at the top edge of the marking area on the shell.

[0008] The present invention further comprises that the channel extends through both ends of the marking block; the bottom end of the second marking block protrudes outside the channel; The second marking component further includes a top block and an elastic support; the top block is located between the marking insert and the elastic support, with one side abutting the bottom surface of the second marking block and the other side abutting the top surface of the elastic support.
[0009] The present invention further provides that the vertical distance between the top surface of the convex rib and the top surface of the marking insert is 0.3-0.5mm.
[0010] In a further embodiment of the present invention, the cross-section of the convex rib is rectangular.
[0011] The present invention further comprises, from top to bottom, the upper mold assembly as follows: an upper mold base, an upper clamping plate, and an upper stripping plate; The lower mold assembly, from top to bottom, includes: a concave mold plate, a lower backing plate, and a lower mold base; The concave template has a positioning groove for positioning the shell; the positioning groove is annular.

[0013] The present invention further includes, in this invention, a guide post as part of the notebook casing marking stamping device; The guide post is disposed on the upper mold assembly; the lower mold assembly is provided with a corresponding guide hole.
[0014] The present invention further provides that the guide posts are provided in multiple forms and are centrally symmetrically distributed; and that the guide holes are correspondingly provided in multiple forms.
[0015] After adopting the above technical solution, the beneficial effects of this invention are as follows: Compared with traditional CNC precision carving technology, this notebook shell marking stamping forming device has higher processing efficiency, does not require frequent replacement of its own components, and avoids leaving tool marks on the shell that affect its appearance. Compared with existing stamping devices, this notebook shell marking stamping forming device has a raised rib on the side of the second marking component facing the upper mold component, and the raised rib is circumferentially arranged along the edge of the end where the second marking block mates with the first marking block, and the raised rib protrudes towards the upper mold component. This arrangement makes the part of the shell that contacts the raised rib (i.e., the connection between the area where the marking is formed on the shell and the peripheral plane area) fit more closely to the corner structure of the stamping end of the first marking component, thereby forming a distinct, sharp, and clear corner structure at the connection between the area where the marking is formed on the shell and the peripheral plane area. This ensures that the edge of the area where the marking is formed on the shell is a clear and sharp corner structure, avoiding the formation of a rounded corner at the top edge of the marking area on the shell due to the shell's own hardness or thickness during stamping, which would otherwise prevent the shell from fitting the corner structure of the stamping end of the first marking block. This allows for precise stamping of sharp-edged logos, preventing consumer misidentification and ensuring consistent surface gloss and color variation during subsequent surface treatments such as polishing, sandblasting, and anodizing. Furthermore, the raised ribs cause the area where the shell contacts the ribs to be recessed towards the upper mold assembly, thinning the connection between the logo area and the surrounding planar area. During stamping, this connection is more prone to forming sharp corners, resulting in a clear and sharp edge structure when viewed from the front. Attached Figure Description

Detailed Implementation
[0019] The present invention will be further described in detail below with reference to the accompanying drawings.
[0020] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.
[0021] This embodiment relates to a notebook computer casing marking stamping device, see reference. Figures 1-9The system includes: an upper mold assembly, a lower mold assembly, a first marking assembly, a second marking assembly, and a rib 500. The first marking assembly is disposed on the upper mold assembly, and the second marking assembly is disposed on the lower mold assembly. The first marking assembly includes one or more first marking blocks 310. The stamped end of the first marking block 310 has a clear, sharp edge structure. One or more ribs 500 are provided. The second marking assembly includes one or more second marking blocks 410. The second marking blocks 410, the first marking blocks 310, and the ribs 500 correspond one-to-one. One end of the first marking block 310 protrudes from the side of the upper mold assembly that mates with the lower mold assembly; the rib 500 is disposed on the side of the second marking assembly facing the upper mold assembly and is circumferentially disposed along the edge of the end of the second marking block 410 that mates with the first marking block 310. The rib 500 protrudes towards the upper mold assembly. When the upper mold assembly and the lower mold assembly are closed, the first marking assembly and the second marking assembly cooperate to stamp a predetermined marking onto the housing 800. Specifically, the logo can be in the form of letters, text, patterns, badges, or a combination of these forms. Compared to traditional CNC engraving technology, this notebook shell logo stamping forming device has higher processing efficiency, eliminates the need for frequent replacement of its own components, and avoids leaving tool marks on the shell 800 that affect its appearance. Compared to existing stamping devices, this notebook shell logo stamping forming device has a raised rib 500 on the side of the second logo component facing the upper mold component. The raised rib 500 is circumferentially arranged along the edge of the end where the second logo block 410 mates with the first logo block 310, and the raised rib 500 protrudes towards the upper mold component (see reference). Figures 3-4 as well as Figure 7 This design, on the one hand, ensures that the part of the housing 800 that contacts the rib 500 (i.e., the connection between the area where the mark is formed on the housing 800 and the peripheral plane area) fits more closely to the corner structure of the stamping end of the first mark assembly. This results in a clearly defined, sharp, and distinct corner structure at the connection between the area where the mark is formed on the housing 800 and the peripheral plane area. This ensures that the edge of the area where the mark is formed on the housing 800 has a clear and sharp corner structure, preventing the top edge of the mark area on the housing 800 from forming a rounded corner due to the housing 800's own hardness or thickness failing to fit the corner structure of the stamping end of the first mark block 310 during stamping. This allows for precise stamping of the sharp-edged logo, avoiding consumer misidentification. Simultaneously, it ensures consistent surface gloss of the housing 800 during subsequent surface treatments such as polishing, sandblasting, and anodizing, and prevents color differences. On the other hand, referring to... Figures 3-4 as well as Figure 7Because the rib 500 causes the area where the housing 800 contacts the rib 500 to be recessed towards the upper die assembly, the connection between the marking area and the peripheral plane area on the housing 800 becomes thinner. During the stamping process, this connection is more prone to forming a corner structure, resulting in a clear and sharp corner structure on the marking area of the housing 800 when viewed from the front. Figures 8-9 ,from Figure 9 In the enlarged schematic diagram at point C, it can be seen that the edge of the marking area of the shell 800, which is stamped by the marking stamping device of the notebook shell, has a sharp and clear edge structure.
[0022] In this embodiment, the convex rib 500 extends vertically toward the upper mold assembly, concentrating the upward thrust on the housing 800. This, in turn, cooperates with the stamping end of the first marking assembly, pushing the housing 800 upward and downward respectively. This creates a shearing force between the two at the marking edge of the housing 800, forcing the housing 800 to fit tightly against the corner structure of the stamping end of the first marking assembly. This results in a marking area with distinct edges and sharp corners being stamped on the housing 800, effectively avoiding the generation of rounded corners.
[0023] Furthermore, all contact surfaces of the rib 500 that come into contact with the housing 800 are planar, and the contact surfaces are vertically connected to each other, ensuring that the housing 800 has a clear and sharp edge profile stamped at the edge of the marking area. Furthermore, the width of the rib 500 is 0.3-0.4 mm. Preferably, the width of the rib 500 is 0.3 mm. In some embodiments, the width of the rib 500 is 0.32 mm, 0.34 mm, 0.36 mm, 0.38 mm, or 0.4 mm.
[0024] In this embodiment, refer to Figure 3 as well as Figure 5The second marking component further includes a marking insert 420 disposed within the lower die assembly. A channel 421 is formed within the marking insert 420; the opening at the top of the channel 421 is located on the top surface of the marking insert 420; the second marking block 410 is placed within the channel 421. The top surface of the marking insert 420 is the side of the second marking component facing the upper die assembly. The marking insert 420 limits the second marking block 410 in the radial direction, ensuring that the second marking block 410 remains axially aligned with the first marking block 310 during the stamping process, avoiding marking contour shift or ghosting caused by radial movement. A raised rib 500 is located on the top surface of the marking insert 420 and is circumferentially arranged along the edge of the opening at the top of the channel 421, so that the edge of the area forming the marking on the housing 800 has a clear and sharp corner structure. In this embodiment, the shape of the rib 500, the inner contour of the channel 421, the outer contour of the first marking block 310, and the outer contour of the second marking block 410 are all the same, ensuring that the marking shape finally formed on the housing 800 is the set marking shape.
[0025] Furthermore, referring to Figures 3-4 The vertical distance between the top surface of the rib 500 and the top surface of the logo insert 420 is 0.3-0.5mm. This avoids excessive height, which could cause the casing 800 to become too thin or even crack, and also avoids excessive shortness, which would prevent the top edge of the logo area on the casing 800 from forming a rounded corner. Preferably, the vertical distance between the top surface of the rib 500 and the top surface of the logo insert 420 is 0.3mm. In some embodiments, the vertical distance between the top surface of the rib 500 and the top surface of the logo insert 420 is 0.35mm, 0.4mm, 0.45mm, or 0.5mm. It should be noted that current laptop casings are divided into A-shell, B-shell, C-shell, and D-shell. A-shell refers to the top cover, B-shell refers to the screen bezel, C-shell refers to the palm rest (the area where the user's wrists and palms rest), which integrates the keyboard mounting area, touchpad area, etc., and D-shell refers to the bottom cover. The logo is usually placed on the A-shell, but can also be placed elsewhere as needed. The thickness of shell A is generally greater than or equal to 1.2 mm, the thickness of shell B is generally greater than or equal to 0.8 mm, the thickness of shell C is generally greater than or equal to 1.3 mm, and the thickness of shell D is generally greater than or equal to 1.2 mm.
[0026] Furthermore, multiple first marking blocks 310, second marking blocks 410, and ribs 500 are provided. Each of the multiple second marking blocks 410, multiple first marking blocks 310, and multiple ribs 500 corresponds to a specific location, ensuring that the connection between the marking area on each housing 800 and the remaining planar areas on the housing 800 forms a clearly defined corner structure. In some embodiments, only one first marking block 310, a second marking block 410, and a rib 500 may be provided.
[0027] Furthermore, referring to Figures 3-5 The channel 421 extends through both ends of the marker insert 420, with the bottom end of the second marker block 410 protruding outside the channel 421. The second marker assembly also includes a top block 430 and an elastic support member 440. The top block 430 is located between the marker insert 420 and the elastic support member 440, with one side abutting the bottom surface of the second marker block 410 and the other side abutting the top surface of the elastic support member 440. The top block 430 effectively supports the second marker block 410 to prevent it from shifting axially along the channel 421. Furthermore, by applying elastic force to the bottom surface of the second marker block 410 through the top block 430, the elastic support member 440 acts as a buffer and shock absorber, effectively preventing the second marker block 410 from cracking or being damaged by rigid impact. In this embodiment, the elastic support member 440 is a spring. In some embodiments, the elastic support member 440 can also be a spring block or other components with elastic support functions.
[0028] In some embodiments, the upper die assembly includes, from top to bottom, an upper die base 110, an upper clamping plate 120, and an upper ejector plate 130. The lower die assembly includes, from top to bottom, a concave die plate 210, a lower pad plate 220, and a lower die base 230. The first marking component is located within the upper clamping plate 120 and the upper ejector plate 130. The second marking block 410 and the marking insert 420 are located within the concave die plate 210, the top block 430 is located within the lower pad plate 220, and the elastic support member 440 is located within the lower die base 230. This arrangement ensures that the upper die assembly can smoothly drive the first marking component and the second marking component to engage, and also prevents the first marking component and the second marking component from shifting during the stamping process. The concave die plate 210 has a positioning groove 211 for positioning the housing 800; the positioning groove 211 is annular. In this embodiment, the shell 800 has a U-shaped cross section and is fastened to the concave template 210. Its bent part is located in the positioning groove 211, and the part that is pre-marked is located inside the positioning groove 211 on the concave template 210.
[0029] Furthermore, referring to Figure 5 as well as Figure 6 The notebook casing marking stamping device further includes a plurality of positioning blocks 600. Positioning holes 212 are provided on the concave template 210 between the positioning groove 211 and the surrounding area of the positioning groove 211 for the positioning blocks 600 to be inserted; multiple positioning holes 212 are provided, each corresponding to a positioning block 600. When the casing 800 is bent and inserted into the positioning groove 211, the sidewall of the positioning block 600 abuts against the outer wall of the bent portion of the casing 800, thereby preventing the casing 800 from shifting to either side during the stamping process. In this embodiment, eight positioning blocks 600 are provided. In some embodiments, four positioning blocks 600 may also be provided.
[0030] In this embodiment, the notebook shell marking stamping device further includes guide posts 700. Guide posts 700 are disposed on the upper die assembly; guide holes 240 are correspondingly provided on the lower die assembly. During the stamping process, the guide posts 700 are first inserted into the guide holes 240 to provide vertical directional guidance for the movement of the upper die assembly, ensuring that the first marking component and the second marking component and the rib 500 in the lower die assembly maintain a precise alignment relationship during each stamping. Furthermore, multiple guide posts 700 are provided and are centrally symmetrically distributed, effectively preventing unilateral swaying of the upper die assembly during stamping. Multiple guide holes 240 are correspondingly provided. In this embodiment, four guide posts 700 are provided, located at the four corners of the upper die assembly, and four guide holes 240 are correspondingly provided.
[0031] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
