Abstract

The utility model discloses a floating suction nozzle mounting pole for welding heads of chip loaders, which comprises a column-shaped support bracket, wherein a nozzle installation supporting rod is arranged in the column-shaped support bracket. A part of the nozzle installation supporting rod extending out of the column-shaped support bracket is provided with a boss, a supporting rod supporting bushing is sheathed outside the column-shaped support bracket and the nozzle installation supporting rod, and the supporting rod supporting bushing is fixedly connected with the column-shaped support bracket. The diameter of the lower end through hole of the supporting rod supporting bushing is smaller than the outer diameter of the boss on the nozzle installation supporting rod, and a vertical moving gap of the nozzle installation supporting rod is arranged between the boss on the nozzle installation supporting rod and the inner surface of the lower end part of the supporting rod supporting bushing. The utility model can reduce the strength and speed of a descending welding head to a frame surface, and the utility model efficiently overcomes chip incline caused by poor back flowing of lead tin.

Description

The floating type suction nozzle mounting rod device of loader soldering tip
Technical field:
The utility model relates to a kind of soldering tip parts that integrated circuit (IC) chip is installed.
Background technology:
At present, generally use the soldering tip that integrated circuit (IC) chip is installed, its pole that suction nozzle is installed is fixed, after the suction nozzle band chip and is placed into the framework surface of slicker solder, rely on the spring force of soldering tip itself to cushion, because the strength that soldering tip descends is big, speed is fast, sometimes slicker solder backflow is not ideal enough, causes that easily chip tilts.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can slow down strength and speed that soldering tip decline arrives the frame table face, overcomes the floating type suction nozzle mounting rod device of the loader soldering tip that tilts owing to the bad chip that causes of slicker solder backflow effectively.
Technical solution of the present utility model is:
A kind of floating type suction nozzle mounting rod device of loader soldering tip, comprise cylindrical stent, the dress suction nozzle is installed pole in the cylindrical stent, at suction nozzle stretching out on the cylindrical stent part of pole is installed, boss is set, it is characterized in that: a pole supporting sleeve is sleeved on outside cylindrical stent and the suction nozzle installation pole, fixedly connected with cylindrical stent, and the diameter of pole supporting sleeve bottom through hole is installed the external diameter of pole convex platform less than suction nozzle, between the boss and pole supporting sleeve bottom inner surface on the suction nozzle installation pole, suction nozzle installation pole is set moves up and down the gap.
The pole supporting sleeve is fixedlyed connected by trip bolt with cylindrical stent.
The utility model is rational in infrastructure, the pole supporting sleeve is fixed on the cylindrical stent, do not install on the pole and do not push up suction nozzle, suction nozzle is installed pole and is supported by the pole supporting sleeve, can not drop, it is movable for cylindrical stent and pole supporting sleeve that suction nozzle is installed pole, and the free travel about 0.8mm is arranged in cylindrical stent and pole supporting sleeve, has so just reached suction nozzle the effect that pole is floated is installed.The moment of chip when the suction nozzle band, can slow down strength and speed that soldering tip descends, just can overcome the bad chip inclination that causes because slicker solder refluxes to the framework surface that slicker solder is arranged.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings:
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
Embodiment:
A kind of floating type suction nozzle mounting rod device of loader soldering tip, comprise cylindrical stent 1, the dress suction nozzle is installed pole 2 in the cylindrical stent 1, at suction nozzle stretching out on the cylindrical stent part of pole 2 is installed, boss 3 is set, a pole supporting sleeve 4 is sleeved on outside cylindrical stent 1 and the suction nozzle installation pole 2, fixedly connected by trip bolt 5 with cylindrical stent 1, and the diameter of pole supporting sleeve 4 bottom through holes is installed the external diameter of pole convex platform 3 less than suction nozzle, between the boss 3 and pole supporting sleeve 4 bottom inner surfaces on the suction nozzle installation pole, the suction nozzle installation pole that is provided with about 0.8mm moves up and down gap 6.
