## Background
CROSS-REFERENCE TO RELATED APPLICATION
This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 099223189 filed in Taiwan, R.O.C. on Nov. 30, 2010, the entire contents of which are hereby incorporated by reference.
FIELD OF THE TECHNOLOGY
The present invention relates to assembly auxiliary jigs, and more particularly, to an assembly auxiliary jig for facilitating assembly of a casing and parts/components of an electronic device.
BACKGROUND
Development of technology-based industries leads to the trend toward diversification of electronic products. Hence, the daily life of human beings nowadays features the use of a wide variety of consumer electronic products, such as mobile electronic devices and wireless electronic devices. The aforesaid mobile electronic devices include mobile phones, multimedia players, portable storage device, etc. The aforesaid wireless electronic devices include wireless Internet cards, wireless chargers, etc. The manufacturing of the aforesaid electronic products entails installing parts and components in the aforesaid electronic products, connecting the parts and components electrically, laminating or packaging the casing of the aforesaid electronic products so as to enhance the durability thereof.
For example, a wireless access point (WAP), whose assembly process is described hereunder, comprises parts and components, such as a casing (composed of an upper casing and a lower casing), a metal leaf spring, a printed circuit board, a wire, wire connection clamps, an antenna, and support stands, etc. The conventional assembly process of a WAP is mostly manually performed, using a production line, by following a process flow comprising the steps of: installing a metal leaf spring, a printed circuit board, and a wire; fixing the antenna to the lower casing by engagement between the antenna and related notches disposed on the lower casing; electrically connecting the antenna to the printed circuit board; tidying up the wire and fixing the wire in place with a wire connection clamp; fixing support stands to the lower casing by engagement between the support stands and related notches disposed on the lower casing; and putting the upper casing on the lower casing to hermetically seal the WAP and thereby finalize the assembly process. Finally, the assembled WAP (i.e., the finished product) undergoes a packaging procedure whereby the upper casing and the lower casing are tightly coupled together by ultrasonic lamination.
The aforesaid conventional assembly process has drawbacks as follows:

    
    
        installing a large number of small parts and components within a crowded space inside a device is so difficult that, at the end of the installation process, some of the parts and components may be missing or unsecured;
        otherwise fastened parts and components may get loosened while leaving one operating point for another one on the same production line during the semi-finished product phase that precedes the packaging phase;
        a likely product defect, that is, scratches and abrasions occur to a casing unduly moved, rubbed, and handled;
        purposely uneven profile of a device or a bump or any other protruding component disposed on the casing prevents the casing from lying flatly and stably and thereby compromises the ease of assembly, for example, to a particularly great extent during the step of putting the upper casing on the lower casing for hermetic sealing, wherein, given a curved profile and shape of a wire, an antenna, support stands, and the lower casing, the casing does not lie stably and flatly to the detriment of the engagement between the upper casing and the lower casing, and a force unduly exerted upon the upper casing and the lower casing in the course of engagement therebetween eventually loosens or damages the parts and components; and
        the assembly process is so intricate that it cannot be performed solely by a single worker and finished once and for all, and in consequence the productivity of the assembly process is low.
    
    


Accordingly, the conventional assembly process is difficult, time-consuming, and susceptible to omission, and cannot be finalized once and for all, thereby resulting in a low conforming rate and deterioration of productivity.
SUMMARY
It is an objective of the present invention to provide an assembly auxiliary jig for facilitating assembly of an electronic device, simplifying an assembly operation, so as to enable a worker to perform an assembly process correctly, quickly, and conveniently and enhance the conforming rate and yield of products.
In order to achieve the above and other objectives, the present invention provides an assembly auxiliary jig for facilitating assembly of an electronic device having a casing, a first fitting, a second fitting, and a wire, the assembly auxiliary jig comprising: a base having therein a receiving space for positioning and receiving the casing and an accessing recess configured to communicate with the receiving space and facilitate access to the casing; a first platform disposed at the base and having a positioning groove in communication with the receiving space, wherein the positioning groove is configured to receive an exposed portion of the first fitting after the first fitting is disposed at the casing; a first lid hinged to the first platform and configured to close the positioning groove so as to ensure an assembly status of the first fitting; a second platform disposed at the base and defined with a positioning recess in communication with the receiving space, wherein the positioning recess is configured to receive an exposed portion of the second fitting after the second fitting is disposed at the casing; and a second lid hinged to the second platform and configured to close the positioning recess so as to ensure an assembly status of the second fitting.
