In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
First introduce the production method of light and thin notebook computer casing.
As shown in Figure 1, light and thin notebook computer casing production method includes:
Step 1: punching press Al-alloy casing；
Step 2: CNC roughing is carried out to Al-alloy casing；
Step 3: T processing is carried out on Al-alloy casing medial surface border surface and forms micropore；
Step 4: connector is placed on Al-alloy casing medial surface corresponding site；
Step 5: carrying out nanometer on Al-alloy casing medial surface border surface and be molded to form plastic parts, and plastic parts will connect
Part wrapping is fixed；
Step 6: after nanometer injection molding in two hours, 145 ~ 150 DEG C are toasted 1 hour；
Step 7: CNC finishing is carried out to Al-alloy casing；
Step 8: anodic oxidation is carried out to Al-alloy casing surface；
Step 9: laser carving is carried out on Al-alloy casing；And
Step 10: drilling is carried out to Al-alloy casing edge.
Referring to figs. 1 and 2, the production method for introducing light and thin notebook computer casing, in step 1 and step 2,
First prepare Al-alloy casing, punching press is carried out to Al-alloy casing, CNC roughing then is carried out to Al-alloy casing, to be made
The preliminary configuration of Al-alloy casing.
In step 3, T processing is carried out to 21 border of Al-alloy casing medial surface and forms micropore.
T treatment process are as follows: ungrease treatment removes product surface greasy dirt；Cleaning, cleans Al-alloy casing, due to
Metalwork is afraid of highly basic, so should be transferred to cleaning immediately after ungrease treatment；Pickling is carried out by acid solution on Al-alloy casing surface
Scoring；T agent etching, etches to form smaller nano-pore on Al-alloy casing surface by T agent.In Al-alloy casing after T processing
The crystal grain of micropore and 50 ~ 80nm that surface forms 20 ~ 40nm protrudes, and plastic cement can securely be tied with Al-alloy casing after being at this moment molded
It closes.
Nanometer injection molding is carried out in Al-alloy casing medial surface border.
Connector is placed before nanometer injection molding on Al-alloy casing medial surface corresponding site, connector can be fastener, even
Fitting, can be for installing hinge near hinge position.In injection molding, connector is wrapped up by the plastic cement of liquid, and plastic cement is cooling solidifying
Gu rear connectors are fixed in plastic parts.
Traditional hot melting way is that molded plastics are placed in after heating fastener, and plastic molting allows fastener to be placed in, and is melted
Solidify after the plastics of change are cooling and fixes fastener.Relative to hot melting way, the present embodiment pre-buried fastener when nanometer is molded, so that
Fastener is wrapped by liquid plastic cement in injection molding and is finally fixed in plastic parts, and at this moment fastener has clear improvement in tension-torsion power,
Reliability requirement at hinge can be met.
In step 6, after nanometer injection molding in two hours, 145 ~ 150 DEG C toast 1 hour, with eliminate Al-alloy casing with
Plastic rubber member surface stress is conducive to preferably be combined between Al-alloy casing and plastic parts.
Nanometer injection molding material used is PPT material, and 30% glass fibre of addition makes moulding have phase with Al-alloy casing
As thermal expansion coefficient.Nanometer injection molding material used can also be PBT material, and 30% ~ 40% glass fibre of addition makes moulding
There is similar thermal expansion coefficient with Al-alloy casing.
In step 7, CNC finishing is carried out to Al-alloy casing, enables aluminum alloy to shell molding.
Such as Fig. 2, in the present embodiment, when CNC roughing, which retains in the aluminium material 23(Fig. 2 at hinge position, has removed aluminium material 23, schemes
The signified position to remove preceding aluminium material 23 of middle label 23), which can be clamped when nanometer is molded to fix Al alloy shell
Body；The aluminium material 23 is removed in CNC finishing.
If there is excessive glue after nanometer injection molding, (or sandblasting) can be polished workpiece to remove excessive glue.It can set and beat
Mill is conventional program, to guarantee the equal overflow adhesive of all workpiece.In addition, excessive glue occurs when in order to reduce injection molding, adjustable mold
Sliding block makes sliding block accurate fit to eliminate die clearance.The means of adjustment mould slide block can be sliding block repair welding, such as corner sliding
Block repair welding, preferably repair welding 0.03mm are also possible to exchange sliding block.
In step 8, anodic oxidation is carried out to Al-alloy casing surface, enhances surface hardness.
In step 9, laser carving, necessary information in printing are carried out on Al-alloy casing.
In step 10, drilling is carried out to Al-alloy casing edge, makes edge bloom, smooth, makes while promoting aesthetics
Feel is more smooth mellow and full.
Step 8 to step 10 is preferred steps, and it is more durable, beautiful can to enable aluminum alloy to shell.
Plastic parts 30 ultimately forms and is attached to 20 medial surface of Al-alloy casing, 21 border.Connector 40 is by comprising being fixed on
In plastic parts 30.
As shown in Fig. 2, light and thin notebook computer casing 10 is the face notebook A shell, that is, corresponding to screen outside
Shell.Certainly, in other technical solutions, the shell at the other positions of notebook, such as the face D shell be can also be.
Notebook computer casing 10 includes Al-alloy casing 20, plastic parts 30 and connector 40.
Al-alloy casing 20 is stamped and formed out by aluminium alloy plate, is had the advantages that good integrity, light-weight and intensity are high, is pen
Remember the main element of this shell 10.
It is combined together between plastic parts 30 and Al-alloy casing 20 by nanometer injection molding, connector 40 is in injection molding by liquid
State plastic cement is wrapped and is finally fixed in plastic parts 30.
Such as Fig. 3, in the present embodiment, 20 periphery of Al-alloy casing forms flanging 22 towards inner bulge.Plastic parts 30 along
Flanging 22 from medial surface 21 to it is remote extend and ride upon flanging 22 in the bending of the most end of flanging 22 use up end face 221.Flanging 22 is use up
End face 221 also passes through T processing and forms micropore, and plastic parts 30 is combined with the most end face 221 of flanging 22.The width of end face 221 to the greatest extent
Ab is 0.8mm, can reach good combination, meet product requirement.Practice have shown that alloy shell 20 and plastic parts after nanometer injection molding
3mm overlapping widths can reach 15kg retentivity between 30, it is seen that pull strength is excellent.
As Fig. 2 buries connector 40 i.e. fastener, pre-buried connector 40 is being molded during nanometer injection molding in mould
It is wrapped and is finally fixed in plastic parts 30 by plastic cement in the process.The connector 40 has interconnecting piece, and interconnecting piece can be interior spiral shell
The forms such as line, external screw thread, interconnecting piece towards the external world, for installed in notebook computer casing 10 other components such as hinge or
LCD screen.
It is all as a result the fracture of plastic parts 30 or aluminium when domain test destructiveness is greater than 15kgf in the present embodiment
Alloy shell 20 deforms, and no plastic parts break-off occurs.There is bright hot melt fastener in tension-torsion power after fastener pulling capacity relatively forms
It is aobvious to improve, reliability requirement at hinge can be met.Degree of deformation also controls in minimum zone after nanometer injection molding.It can be seen that just
Under true process conditions, the plastic cement of nanometer injection molding and the binding force of metal, the better than heat in the manufacture of traditional notebook computer casing
Bonding.Nail is buried in nanometer injection mould compared to conventional hot melt fastener, also more saves manpower and cost, fastener tension-torsion power are also more excellent.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention,
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
