ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an assembling system of rubber cones of computer keyboards and an assembling method for the same and, more particularly, to an assembling system of rubber cones of notebook computer keyboards and an assembling method for the same.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a key switch of a prior art computer keyboard comprises a key top
11
a,
a rubber cone
12
a,
two levers
13
a
and
14
a
in scissors arrangement, a circuit board
15
a,
and a base
16
a.
The top ends of the two levers
13
a
and
14
a
are connected to the bottom pier of the key top
11
a,
and the bottom ends thereof are fastened to the base
16
a.
The rubber cone
12
a
is arranged between the key top
11
a
and the base
16
a.
Tie circuit board
15
a
is spread over the surface of tile base
16
a
so that a contact can be formed on the circuit board
15
a
when the key top
11
a
and the rubber cone l
2
a
are pressed.
Therefore, how to arrange the rubber cones
12
a
on predetermined positions on the circuit board
15
a
accurately and quickly in the procedure of assembling keyboards is a very important problem.
In the prior art, a moldboard
17
a
(shown in
FIG. 2
) having a plurality of recesses
18
a
is provided. The plurality of recesses
18
a
correspond to the key switches of a notebook computer keyboard. When a workpeople places a large quantities of rubber cones
12
a
on the surface of the moldboard
17
a
and then rocks the moldboard
17
a
to an fro with both hands, the rubber cones
12
a
will jump and fall into the recesses
18
a
of the moldboard
17
a.
This method is commonly used in the assembling procedure of desktop computer keyboards. However, because the sizes of notebook computers become more and more compact, the above method cannot assure that all the recesses
18
a
will be filled. The non-filled recesses
18
a
need to be filled manually.
The conventional method has the following drawbacks. First, because a workpeople only rocks a moldboard each time, the assembly efficiency is very low. Second, because the assembling procedure totally relies on manpower, the cost will be considerable, and economy cannot be enhanced.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide an assembling system of rubber cones of computer keyboards and an assembling method for the same, thereby partly automating the originally wholly-artificial assembling method, increasing assembly efficiency, and effectively enhancing economy.
To achieve the above object, the present invention provides an assembling system of rubber cones of computer keyboards and an assembling method for the same. The partly automated assembling system of rubber cones of computer keyboards of the present invention comprises an assembly housing, a moldboard stage, a rocking apparatus, and a rotating apparatus. The assembly housing has an operational space. The moldboard stage has a plurality of moldboard, and is arranged above the operational space of the assembly housing. Each moldboard corresponds to a keyboard to be assembled, and has a plurality of recesses corresponding to key switches of the keyboard on the surface thereof. The rocking apparatus and the rotating apparatus join with the moldboard stage at two sides thereof to provide required rocking and rotating forces for the moldboard.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings, in which:
