Fig. 1 is referred to, the electronic product casing processing method that the present invention is provided, step includes;
S10, offer metalwork to be processed.The metalwork to be processed can be the metal shell hair gone out by metallic plate punching Base, sheet metal can be using aluminium alloy, magnesium alloy, titanium alloy etc..
S20, synchronous roughing connecting hole and datum hole, the company that the connecting hole is used for for outside on metalwork to be processed Wiring grafting.Connecting hole can be earpiece holes, USB holes, and datum hole is located at the side of connecting hole, and the cross section of datum hole is circle Or square.
S30, metalwork to be processed is molded, the metal plastic part that metal and plastic cement are combined, injection are obtained after injection When plastic cement flow into connecting hole, after solidification, plastic cement is full of in connecting hole.
S40, the connecting hole on metal plastic part is finished according to the center of datum hole, after finishing, gone Except the plastic cement in connecting hole and the plastic cement of the axial direction along connecting hole, housing semi-finished product are obtained.
S50, the clout for milling housing semi-finished product, obtain housing finished product.Now, datum hole is by mill off, after finishing Connecting hole has good axiality, and the plastic uniform degree of connecting hole surrounding is good.Using electronic product casing processing side of the present invention Method, the housing finished product yield after its processing is high.
In more detail, step S40 includes:The concentricity of the datum hole on metal plastic part is entered with concentricity meter Row is detected and obtains the center of datum hole, and the center of the datum hole obtained according to detection is calculated in connecting hole Heart position, then to calculate that the center of the connecting hole for obtaining finishes to the connecting hole, obtain housing semi-finished product.
By taking processing mobile phone metal shell as an example, its procedure of processing is:
As shown in Figure 2 and Figure 3, in the upper surface synchronization roughing earpiece holes 110 of metal shell blank 100 and the first base Quasi- hole 111, in the lower surface synchronization roughing USB holes 120 of metal shell blank 100 and the second datum hole 121, the first benchmark The datum hole 121 of hole 111 and second is in the expectation part processing of metal shell blank 100, the first datum hole 111 and the second benchmark Hole 121 is blind hole.
As shown in figure 4, be molded to metal shell blank 100, make upper and lower ends inside metal shell blank 100 Plastic cement is full of in antenna slot and in earpiece holes 110 and USB holes 120, the metal plastic that metal is combined together with plastic cement is obtained Part 200.
The first datum hole 111 is detected with concentricity meter (not shown), the center of the first datum hole 111 is obtained Afterwards, the center according to the first datum hole 111 calculates the center of earpiece holes 110, then finishes earpiece holes 110.Such as Fig. 5 Shown, after earpiece holes 110 are finished, plastic cement in earpiece holes 110 and the plastic cement along the axial direction of earpiece holes 110 are removed.
The second datum hole 121 is detected with concentricity meter, after obtaining the center of the second datum hole 121, according to the The center of two datum holes 121 calculates the center in USB holes 120, then finishes USB holes 120, the plastic cement in USB holes 120 And be removed along the plastic cement of the axial direction of USB holes 120.
CNC mill off clouts, obtain mobile phone metal shell.
The cross section of the first datum hole 111 and the second datum hole 121 is circle, and its process velocity is than processing cross section For the speed of foursquare datum hole is fast, axiality is also higher.
As shown in Fig. 3, Fig. 6, when synchronous processing earpiece holes 110 and the first datum hole 111, the first datum hole 111 and earphone Hole 110 is machined in the top surface of metal shell blank 100, and the first datum hole 111 is near earpiece holes 110.By the first datum hole 111 center of circle side more long with the top of metal shell blank 100 with the straight line in the center of circle of earpiece holes 110 is parallel, the first datum hole 111 diameter is less than the diameter of earpiece holes 110, to improve process velocity.
When synchronous processing USB holes 120 and the second datum hole 121, the second datum hole 121 is machined in metal with USB holes 120 The bottom surface of outer sleeve blank 100, the second datum hole 121 is near USB holes 120.By the center of circle and USB holes 120 of the second datum hole 121 Center the straight line side more long with the bottom of metal shell blank 100 it is parallel, the diameter of the second datum hole 121 is less than USB holes 120 Width, to improve process velocity.The axiality of the connecting hole after finishing is high, and the plastic uniform degree in connecting hole is high, mobile phone The yield of metal shell is high.
Electronic product casing processing method of the invention, connecting hole and datum hole are synchronous processing, after injection Center according to datum hole finishes to connecting hole, can obtain the connecting hole of high-axiality, the modeling of connecting hole surrounding Glue is uniform, and the housing finished product yield after being processed using the method is high.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses several embodiments of the invention, and its description is more specific and detailed, but simultaneously Can not therefore be construed as limiting the scope of the patent.It should be pointed out that coming for one of ordinary skill in the art Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
