More preferably, the said first trigger blocks installing plate is provided with first slotted eye that is provided with along the first slide glide direction, and said first sensor trigger blocks is fixed through first latch segment that passes first slotted eye; The said second trigger blocks installing plate is provided with second slotted eye that is provided with along the second slide glide direction, and said second trigger blocks is fixed through second latch segment that passes second slotted eye; The installation site of sensor-triggered piece can be regulated in slotted eye according to the spacing of solder joint, only need latch segment be turned on during adjusting, moves to latch segment to be tightened after the desired location to get final product again, and is convenient and swift.
As preferably, be respectively equipped with the first band-type brake magnetic valve and the second band-type brake magnetic valve on the piston rod of said first cylinder and second cylinder, cylinder drives slide and the motion of trigger blocks installing plate; When the sensor-triggered piece moves to the inductive switch place of corresponding sensor with the trigger blocks installing plate; Sensor has a signal and sends and pass to cylinder solenoid valve and band-type brake magnetic valve, and the band-type brake magnetic valve is embraced the piston rod of cylinder, realizes the location; The band-type brake magnetic valve makes positioning accuracy higher; Bond pad locations can access good assurance, and when soldering turret was opened after welding is accomplished, sensor also had a signal and gives band-type brake magnetic valve and cylinder solenoid valve; The band-type brake magnetic valve is unclamped, the cylinder piston rod motion.
As preferably, said base comprise up and down two base plates and between two base plates supporting seat, the height of supporting seat can be changed according to the height adjustment of vehicle body, be equivalent to one and mend high platform, and is convenient and simple.
The utility model assembling is simple, and compact conformation can realize simultaneously that auto soldering tweezers moves and locatees along Y direction and Z direction, on welding and assembling production lines, has saved the space greatly, has reduced manufacturing cost; The utility model accurate positioning guarantees tram and quality of welding spot that solder joint welds.
