System and apparatus for screws automatic loading, delivering, and a screwdriver set for fetching and fastening screws on a target
View Patent ↗A system for screws loading, delivering, fetching and fastening on a working piece is disclosed. The screws are guided by an apparatus having a control module to pass a track, a chute and received by a cut of a graduated disc having a plurality of cuts at the circumference thereof. A screwdriver set is then controlled by the control module to fetch the screws at the cuts in a fetching cycle and fasten them to a working piece.
1. A screw loading and delivering apparatus comprising:
a container for containing screws;
a bevel track for transporting screws from an outlet of said container to an outlet of said track;
a control module;
a first detecting sensor for detecting whether a screw is ready at said outlet of said track;
a chute having a slide bar moving along said chute;
a gas blow pipe to blow any screw right at said outlet of said track to a first position in said chute, and said screw is pushed to a second position in said chute by said slide bar;
a second detecting sensor for detecting whether the screw is at said second position; and
a graduated disc seated on a base and capably of rotating with a programming turning angle about a rotating axis controlled by said control module, wherein said graduated disc has a plurality of cuts formed and distributed at a circumference of said graduated disc for receiving the screw at said second position.
2. The screw loading and delivering apparatus according to claim 1 , wherein said first and second detecting sensors both comprise an optical fiber and a photo sensor to determine whether the light outputted from said optical fibers being masked by the screw or not.
3. The screw loading and delivering apparatus according to claim 1 , wherein said control module has control units to control a valve of said gas blow pipe, a moving of said slide bar, and said programming control after the light is masked out by the screw.
4. The screw loading and delivering apparatus according to claim 1 , wherein said bevel track is supported by an elastic member to make said track vibrated so as to prevent screws at said track from jamming.
5. The screw loading and delivering apparatus according to claim 1 , further comprising a circle groove formed around said circumference of said base so that the screws clamped at said cuts moving along said circle groove would not be dropped out while said graduated disc is turning.
