Description

Production process and production line for metal shell of notebook computer

Technical Field

The invention belongs to the technical field of shell accessories of electronic equipment, and particularly relates to a production process and a production line for a metal shell of a notebook computer.

Background

With the advancement of technology, in addition to the functions and performances of electronic devices such as notebook computers, personal digital assistants, mobile phones, and music players, the housings of the electronic devices are increasingly innovative and improved in light weight, miniaturization, firmness, anti-falling, anti-pressure, and beautiful appearance. The shell of the electronic device can be made of ABS engineering plastics and PC polycarbonate. The ABS engineering material has better plasticity, is applied to products with complex shapes, but has high density and poor thermal conductivity; PC polycarbonate also has good plasticity and good heat dissipation, but it has poor abrasion resistance. In order to improve the thermal conductivity and wear resistance, some electronic device housings have been made of metal materials with good thermal conductivity and high hardness, such as magnesium aluminum alloy, titanium alloy, and stainless steel. However, in the electronic device case made of metal, a case having a specific shape is formed by die casting, stamping, injection molding, or the like, and then the metal case is anodized to form a surface protection layer and a metallic luster, or the surface of the case is shaped by a sand blasting process. However, the above-mentioned processing process is generally difficult to form patterns or designs with three-dimensional visual and tactile senses on the surface, and thus the appearance requirements of the electronic device are often not satisfied. Meanwhile, electronic device housings made of metal are often single-layer structures, and some materials may provide a desired performance level relative to some characteristics, but may not provide an optimal performance level relative to other characteristics.

As shown in fig. 1, in the production process of the metal shell of the notebook computer provided in this embodiment, a metal substrate 6 having a first material characteristic, a metal lining 7 having a second material characteristic, and a metal braid 8 having a third characteristic are prepared; then, the inner surface of the metal base 6 is bonded with the metal lining 7, and the outer surface is bonded with the metal braided fabric 8.

Specifically, in some examples, a metal case for a notebook computer may include a preformed metal base having a first material property, a preformed metal liner having a second material property, and a preformed metal braid having a third material property. The preformed metal matrix and metal lining may be stamped or cast, while the preformed metal braid may be stamped or woven. The preformed metal matrix and metal liner may be welded or adhesively joined together such that they form a substantially monolithic body. And the preformed metal matrix and the metal braided fabric can be bonded together by powder or welded by laser, so that the shell has stereoscopic appearance and touch. In addition, the metal matrix may have a first material property selected to exhibit one or more properties, while the metal liner may have a second material property selected to exhibit another or other desired property independently of the first material property, and the metal braid may have a third material property selected to exhibit one property independently or identically to the first material property. That is, the metal liner may be selected to achieve strength, weight, stiffness, cost, thermal conductivity, machinability, recyclability, etc.; the metal matrix can be selected to achieve properties of hardness, corrosion resistance, scratch resistance, aesthetic finish, strength, weight, stiffness, cost, thermal conductivity, machinability, recyclability, and the like; the metal braid can be selected to achieve properties of hardness, corrosion resistance, scratch resistance, aesthetic finish, weight, cost, thermal conductivity, processability, recyclability, and the like. For example, the metal matrix and the metal braided fabric are both made of stainless steel, and the metal lining is made of aluminum. Thus, the aluminum metal liner has the characteristics of light weight, low cost and easy processing, while the stainless steel metal matrix provides high hardness, corrosion resistance and scratch resistance outside the metal liner, and the stainless steel metal braid provides an aesthetic finish and heat dissipation outside the metal matrix.

As shown in fig. 2, the production line related to the metal shell production process in the present embodiment includes a main transport line 1 for transporting a metal base 6, a first sub-transport line 2 for transporting a metal lining 7, a second sub-transport line 3 for transporting a metal braid 8, a turnover mechanism 4 disposed on the main transport line 1 for turning over the metal base 6, and a fastening mechanism for respectively bonding the metal lining 7 and the metal braid 8 to the metal base 6.
