Description

Technical Field

[0001] The invention relates to the technical field of notebook computer shell manufacturing engineering, and in particular to a notebook computer shell processing technology. Background Art

[0002] The conventional manufacturing process of the aluminum alloy case of a laptop computer includes: first, stamping the aluminum alloy sheet, then using a CNC machine to accurately process the required wall height, length and width, then grinding the shell, then sandblasting the surface, and then anodizing it, and finally assembling it through AB glue hot pressing plastic frame. For example, the laptop shell similar to hinge boss is made of plastic or magnesium, aluminum alloy and other structural parts through AB bonding.

[0003] We found that the disadvantage of this process of stamping aluminum alloy sheets and then bonding internal components with AB glue is that the AB glue bonding process has very high requirements for construction conditions and parameter control, and the construction risk is high, which can easily lead to debonding or insufficient bonding strength due to conditions and parameters. Even if there are no problems with the construction, the bonding strength of the AB glue will be affected by the size of the bonding area of ​​the internal components, and there are often process bottlenecks in the bonding strength of special positions, which cannot meet the structural strength requirements. The AB glue bonding surface has the risk of environmental resistance, which affects the service life of the casing. At the same time, during the AB glue bonding process, some key structures may be displaced, affecting the assembly performance of the aluminum alloy casing of the laptop computer. In view of this, we specially applied for this invention. Summary of the invention

[0025] Process parameter control: The parameters of metal powder high-speed cold spraying and CNC machining need to be precisely controlled to ensure product quality.

[0026] Cost-effectiveness: Although the initial investment in cold spray equipment may be high, in the long run, the overall manufacturing cost may be reduced due to the improved material utilization and possible improvement in the efficiency and stability of the casing AB bonding construction.

[0034] In order to more clearly illustrate the purpose, technical solutions and advantages of the present invention, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Please note that the specific embodiments mentioned are only intended to illustrate the present invention, rather than to limit its scope of application.

[0035] Embodiment 1: This solution describes in detail a manufacturing process of a notebook computer casing, and the specific steps are as follows: First, the aluminum alloy sheet is stamped to form an aluminum alloy casing 1 that meets the design requirements, see Figure 1 As shown; in specific locations of the aluminum alloy housing, such as the stud structure used to assemble the hinge shaft, we use metal 3D additive technology combined with advanced CNC processing methods to accurately process the required high-strength fine structure, see Figure 2 and Figure 3 As shown; Next, the aluminum alloy shell that has been processed by metal 3D additive technology and CNC is polished and sandblasted to ensure a smooth and neat surface; then, the polished and sandblasted aluminum alloy shell is anodized, which not only completes the appearance of the aluminum alloy shell, but also enhances the corrosion resistance and wear resistance of the shell. Finally, the internal structure is added to the specific area of ​​the laptop shell 4, see Figure 4 As shown, these internal structures are bonded by using AB glue to form the final product of the notebook computer case. This solution significantly improves the structural strength and stability of specific positions of the notebook computer aluminum alloy case (such as the hinge shaft locking position), so that the overall strength, assembly performance, service life and quality of the notebook computer aluminum alloy case are significantly improved.

[0036] The 3D additive technology used in this solution specifically refers to the metal powder high-speed cold spraying process, which is an advanced manufacturing technology. The metal powder high-speed cold spraying additive technology uses nitrogen and other gases with a certain temperature and pressure to drive the metal powder and accelerate it to supersonic speed, so that the powder particles hit the surface of the substrate at high speed, undergo violent plastic deformation in the solid state and combine together to form a stable and high-strength metal additive body. This technology can be used to perform fast and precise 3D additive processing on specific locations of the aluminum alloy case of laptop computers.

[0037] Embodiment 2: This solution describes in detail a manufacturing process of a notebook computer casing, and the specific steps are as follows: First, the aluminum alloy sheet is stamped to form an aluminum alloy casing 1 that meets the design requirements, see Figure 1 As shown; in specific locations of the aluminum alloy housing, such as the stud structure used to assemble the hinge shaft, we use metal 3D additive technology combined with advanced CNC processing methods to accurately process the required high-strength fine structure, see Figure 2 and Figure 3 As shown; Next, the aluminum alloy shell that has been processed by metal 3D additive technology and CNC is polished and sandblasted to ensure a smooth and neat surface; then, the polished and sandblasted aluminum alloy shell is painted. This process not only completes the appearance of the aluminum alloy shell, but also enhances the corrosion resistance and wear resistance of the shell. Finally, the internal structure is added to the specific area of ​​the laptop shell 4, see Figure 4 As shown, these internal structures are bonded by using AB glue to form the final product of the notebook computer case. This solution significantly improves the structural strength and stability of specific positions of the notebook computer aluminum alloy case (such as the hinge shaft locking position), so that the overall strength, assembly performance, service life and quality of the notebook computer aluminum alloy case are significantly improved.

[0038] The 3D additive technology used in this solution specifically refers to the metal powder high-speed cold spraying process, which is an advanced manufacturing technology. The metal powder high-speed cold spraying additive technology uses nitrogen and other gases with a certain temperature and pressure to drive the metal powder and accelerate it to supersonic speed, so that the powder particles hit the surface of the substrate at high speed, undergo violent plastic deformation in the solid state and combine together to form a stable and high-strength metal additive body. This technology can be used to perform fast and precise 3D additive processing on specific locations of the aluminum alloy case of laptop computers.

[0039] In the new manufacturing process, through the precise control of metal powder deposition by metal 3D additive manufacturing technology, we are able to produce an integrated metal structure that is firmly bonded to the aluminum alloy shell and has higher strength, is more complex and refined, which is difficult to achieve in the traditional process of stamping combined with AB bonding of internal components. The new process simplifies the steps of AB glue bonding of internal components, which not only reduces the potential risk of debonding due to AB glue construction risks, insufficient bonding area, aging of adhesives, etc.; it also avoids the problem of internal component displacement during the bonding process, and improves the dimensional stability and assembly performance of the laptop computer case. Ultimately, while meeting the appearance and styling structure requirements of the laptop computer, the case product can achieve higher strength and durability, and better meet the needs of modern laptops for thinness and high performance.

[0040] Products formed in specific applications, such as Figure 4 As shown, the present invention relates to a laptop computer case product structure, which comprises a shell 1; a processing part 2 arranged on the shell 1, the processing part being made of metal 3D additive; a structure 3 formed by CNC finishing of the processing part 2; and an internal structure 4 arranged at other positions on the shell 1, the internal structure 4 being fixed to the shell 1 by an AB adhesive.

[0041] In the new manufacturing process, the introduction of metal 3D additive manufacturing technology has greatly improved the freedom of laptop case design, accelerated the design iteration process, and enabled designers to quickly transform their ideas into physical products within reach. The implementation of the new manufacturing process has significantly improved the structural strength, assembly performance, and service life of laptop case products, which is a manifestation of the overall improvement in the quality of laptops. The implementation of the new manufacturing process has also simplified the AB glue bonding process of laptop cases, shortened the production cycle, and improved the flexibility of the production line; in addition, it has also reduced the generation of waste during the AB glue bonding process, effectively reducing the environmental burden, which coincides with the green development concept pursued by the current manufacturing industry. The new manufacturing process can help laptop manufacturers provide more diversified and personalized products and better meet the needs of different consumers through innovative improvements in the manufacturing of laptop cases.
