The present invention is using the double-deck carrier runner design, and every layer drives carrier to flow into or flow back by unilateral belt line, in addition
Support is made by plastic shaft in side, reduces frictional force, and have self-lubricating function, belt line body is combined by engineering plastics with aluminum profile
It forms, portable construction, is suitble to electronic manufacture production line, tool antistatic requirement.Carrier has the lid of imitative mainboard heat ink, to master
Plate accurate positioning, when the fashionable carrier lid of carrier flow is positioned by self-locking grab.After flowing into carrier, front has blocking close to biography
When sensor senses, stop cylinder, which is stretched, stops carrier positioning, and then lifting body is risen carrier de- by cylinder movement
From belt line, carrier mainboard enters to work state at this time, and lock screw batch carries out assembling screw respectively.
The present invention at work, includes the following steps:
Original state: the movement of XY axis is reset to above screw feeder outlet, and Z axis first stroke is in upper end, Z axis second
Stroke is in upper end；
Enabling signal: carrier positioning inductor has signal, lifting device rise or screw loader to have feed signal.
Screw: XY axis movement is drawn, until surface of the suction nozzle to positive screw loader output screw, Z axis first stroke, the
Two itinerary parts move, and contact screw head surface is delayed after suction nozzle elder generation urgency, draws 1 screw on head.
Lock screw: XY axis is moved to right above the screw hole of screw to be locked；The starting of Z axis first stroke drive motor, screwdriver
Stop after being quickly displaced downwardly to the triggering of first stroke inductor；Second stroke drives cylinder starting, screw batch initiation, until the second row
Journey inductor triggering or timing to trigger.
Screwdriver is retracted: screwdriver stops operating and refunds 1/20 circle (easily exiting screw notch convenient for screwdriver bit), second
Stroke driving cylinder is retracted, and the revolution of first stroke driving motor stops at Z axis initial position.
Reset: the linkage of XY axis allows electric screwdriver to return to position of readiness, waits next cycle.
The present invention is specific to a station in production line, i.e. assembling notebook radiator (heatsink), originally by people
Work locks screw, now conveys screw and automatic assembling screw by machine auto-feeder, cost of labor is greatly saved, improves life
Produce efficiency.
