The specific embodiment
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
A kind of pneumatic robot soldering turret comprises that bracket component is installed on robot end's the joint by bracket component 11, float base assembly and transformer 2, and unsteady base assembly is installed on the bracket component, and transformer is installed on the base assembly that floats.
The concrete structure of each parts is:
(1) bracket component is a U font structure, is provided with the installed part that mechanical robot end joint is installed at its bottom surface middle part, is shaped on the screw of installing mutually with unsteady base assembly on the vertical plates on both sides of bracket component, and the base assembly that will float thus is fixed on the bracket component.
(2) unsteady base assembly comprises the float pedestal 3 and the assembly that floats, the vertical plates on both sides of unsteady pedestal and bracket component adopts screw to be fixed together by the screw that is shaped on the bracket component vertical plates on both sides, the both sides lateral symmetry of unsteady pedestal is provided with two fairleads 13, be fixed with a locking riser 14 between two fairleads, the assembly that floats is installed in these two fairleads.
Unsteady assembly comprises master cylinder 12, movable weldering arm 8, fixing weldering arm 6 and lock-up cylinder 17, bilateral symmetry at master cylinder is fixed with two axis of guides 10, these two axis of guides can coaxially be fit in two fairleads of the pedestal that floats, and realize the displacement to axial with unsteady pedestal.The front end of the piston rod 9 of master cylinder is equipped with movable weldering arm, and the front end of this activity weldering arm is coaxial, and fixing weldering arm is packed on the master cylinder directly to fixing weldering arm, and the end of fixing weldering arm and movable weldering arm is equipped with welding electrode 7.Be coaxially installed with lock-up cylinder on master cylinder top, extended and the top of the piston rod of this lock-up cylinder is contained on the locking riser of the pedestal that floats, realize the relative fixed of whole unsteady assembly and unsteady pedestal thus, after piston rod discharges, realize the relative displacement of unsteady assembly and unsteady pedestal; Also install a locking base plate 15 in the master cylinder rear end at locking riser rear, on the locking base plate of corresponding lock-up cylinder piston rod, be coaxially installed with an adjustment screw 16, be used to regulate the displacement of unsteady pedestal and lock-up cylinder, on the axis of guide that floats between pedestal and the locking base plate, balancing spring 1 be installed.
(3) transformer directly is packed on the pedestal that floats, and the secondary end tab 4, the busbar 5 that install by the transformer front end directly are connected with fixing weldering arm.
The pneumatic robot soldering turret can be in the unspecified angle work between level arrives straight down generally speaking, and wherein operating position straight down is to weld arm following, and master cylinder is in last position.Be example now, its course of work be described with pneumatic robot soldering turret operating position straight down:
After system started, robot drove the pneumatic robot soldering turret and moves to workpiece from original position.At this moment, the lock-up cylinder piston rod stretches out and withstands on the locking riser of the pedestal that floats, piston rod continuation elongation along with lock-up cylinder, the cylinder body of lock-up cylinder drives elastic force that the assembly that floats overcomes balancing spring to stretching out the opposite direction motion of direction with piston rod, till regulating the locking riser that dog screw withstands on the pedestal that floats.This moment, the unsteady assembly of soldering turret was in the lock position, when robot drives its motion, unsteady assembly can not produce displacement, can avoid the parts damages that the floating member action caused because of pneumatic robot soldering turret motion, when improving the soldering turret reliability, also guarantee the precision of subsequent control action.This moment, the piston rod overhang of master cylinder was the shortest, and the distance between the welding electrode of the welding electrode of movable weldering arm and fixing weldering arm is maximum, so the position is the big open position of soldering turret.When soldering turret was in big open position, robot can drive it and avoid complex-shaped workpiece or anchor clamps, and it is moved to the bond pad locations of workpiece.
Arrive the bond pad locations of workpiece when soldering turret after, the distance of arm to fixing weldering arm direction motion one regulation welded in the piston rod drive activity of master cylinder, makes the distance shortening between the welding electrode of fixing weldering arm and movable weldering arm.What this position was called soldering turret opens ready position for a short time.This moment, workpiece was positioned at the centre position between fixing weldering arm welding electrode and movable weldering arm welding electrode, and two welding electrodes are vertical with the plane of workpiece bond pad locations, and whole unsteady assembly still is in the lock position.
After soldering turret arrived ready position, the piston rod of lock-up cylinder was regained, and the locking effect of the assembly that floats is eliminated.Balancing spring elongation also drives whole unsteady assembly towards the motion of balancing spring prolonging direction, and till the gravitational equilibrium that pressure and unsteady assembly that balancing spring is subjected to are subjected to, the elongation of spring just in time makes the fixing welding electrode that welds arm contact with workpiece.Meanwhile, the piston of master cylinder continues protruding, and the welding electrode that welds arm until activity contacts with workpiece.Because of the elastic force of float assembly gravity and balancing spring balances each other, thus workpiece to be subjected to fixing weldering arm welding electrode pressure less, be difficult for producing distortion, guaranteed the welding quality of workpiece and reached welding precision.In addition, when error appears in the size of electrode generation wearing and tearing or workpiece, fixing weldering arm can't contact with workpiece, then can weld the welding electrode of arm and the reaction force that workpiece offsets by activity, make the fixedly weldering arm in the unsteady assembly that is in quick condition shift to workpiece and inconsistent with workpiece, can compensate the low error that causes of dimensioned precision so effectively, further guarantee the welding quality of workpiece because of wear to electrodes or workpiece.
Behind the soldering turret clamping work pieces, connect transformer frequency response, finish the spot weld operation of workpiece.
For the welding position of different lateral attitudes and the workpiece of different size, only need to select the balancing spring of different hardness, can the unsteady assembly weight of balance can realize fixing weldering arm welding electrode and workpiece excellent contact again, guarantee welding quality and welding precision.And when soldering turret is the level use, then only need removes balancing spring and get final product.
