Synchronous belt is connected with the tight block in belt town；Sliding block is installed on rear side of the installation pedestal, sliding block clamping is mounted on chip mounter
On slide.
As further program of the utility model：It is described to be connected into air parcel by pipeline with external air source, and connecting
Pipeline is equipped with solenoid valve.
As the utility model further scheme：The closed loop stepper motor and solenoid valve pass through conducting wire and outside
Power supply is connected, and is in series with switch and relay on respective link circuit.
As the utility model further scheme：The outer power voltage is 220V.
Compared with prior art, the beneficial effects of the utility model are：
1st, suction nozzle rod and motor shaft are directly connected to by positive coupling, completely eliminate the mistake that other drive mechanisms are brought
Difference, the rotating accuracy of closed loop motor is the rotating accuracy of suction nozzle rod, greatly increases the rotating accuracy of suction nozzle rod, preferably
Meet high-precision attachment demand.
2nd, suction nozzle rod and motor shaft are direct-connected, and suction nozzle rod is turned round in bearing, form attachment module；Belt connects with attachment module
It connects, motor drives belt, so as to which attachment module be driven to carry out Z-direction movement under slide guiding, is not required purchasing price high
Import spline and sleeve reduce cost, and are easier to realize.
