Auto-assembling system for small shell devices

An auto-assembling system, comprising:

• a track with a left handrail, a right handrail and a inside handrail wherein said inside handrail is positioned between said right handrail and said left handrail;
• a slide way with a left handrail, a right handrail and a inside handrail, wherein said inside handrail is positioned between said right handrail and said left handrail and said slide way positioned on said track and a tilt angle exists between said slide way and said track;
• a first transportation apparatus including a first transportation belt for transporting a first item to said slide way;
• a second transportation apparatus including a second transportation belt for transporting a second item to said track, wherein said first transportation apparatus is positioned on said second transportation apparatus, wherein said second driving module has a motor, a driving stick placed on said track and a gear connected to said motor and said driving stick, whereby said driving stick moves reciprocally along said track;
• a first driving module connected to and positioned on said first transportation apparatus for driving first item along said slide way to said track, wherein said first driving module has a motor, a rack positioned on said slide way and a gear connects said motor and said rack, whereby said first driving module moves reciprocally along said slide way;
• a second driving module connected to and positioned on said second transportation apparatus for driving said second item transported by the second transportation apparatus to an assembling section through said track, wherein said first transportation apparatus is mounted on said second transportation apparatus;
• a power assembling module includes a motor, a gear connected to said motor, and a rack connected to said gear, wherein said rack is connected to a pressing cubic mold, whereby said pressing cubic mold is capable of exerting pressure on said first item vertically and downwardly for combining said first item and said second item, and wherein said power assembling module positioned besides an end of said first transportation component that said first item is transported to;
• and
• a control circuit connects the first transportation apparatus, said second transportation apparatus, said first driving module, said second driving module and power assembling module for driving them.
