Description
Technical field：
The present invention relates to the technical field of stannum ball manufacturing equipment, more specifically on a kind of BGA stannum ball forming device
Sensor construction.
Background technology：
BGA stannum ball is the pith of BGA welding, and automatic BGA stannum ball feed mainly has the cutting remelting method of forming and injection
Two kinds of the method for forming, the former is the unit that the solder stick of different-diameter is cut into uniform quality, then is fused in glycerol
Ball；The latter is solder to be placed in specific container (crucible) melted, and then inflates in crucible, and increasing pressure makes fusing
Solder afterwards sprays from the specific aperture of crucible bottom, reuses the higher-order of oscillation and is allowed to balling-up.When above-mentioned two kinds form
It is suitable for and produces in enormous quantities, it needs, and equipment is complicated and cost is larger；And some small lot samples are manufactured, it is general
Operated using the simple Casting Equipment of some structures, the mould of Casting Equipment is typically provided steam vent, steam vent is connected
Exhaustor, exhaustor is installed pressure transducer, and gas in mould enters the pressure value of exhaustor compression variation to control simultaneously
The conveying of tin liquor processed, and the pressure transducer probe in current exhaustor is directly contacted with expellant gas in mould, its gas
There is higher temperature, easily cause the damage of pressure transducer, or the also droplet with some tin liquors in gas, also easily make
Become the damage of pressure transducer.
Content of the invention：
The purpose of the present invention is aiming at the deficiency of prior art, and provides the biography on a kind of BGA stannum ball forming device
Sensor structure, it has completely cut off pressure transducer and expellant gas in casting mould, thus protecting pressure transducer.
For achieving the above object, technical scheme is as follows：
A kind of sensor construction on BGA stannum ball forming device, including be connected with BGA stannum ball casting mould steam vent
Trachea, trachea is made up of the tubule of bottom and the extra heavy pipe on top, and the top of extra heavy pipe is fixed with capping, capping is fixed with pressure and passes
Sensor, the probe of pressure transducer is plugged in extra heavy pipe, is plugged with piston in extra heavy pipe, and piston is resisted against the top of tubule, described
Tubule on grafting be fixed with relief tube, relief tube is fixedly connected with electromagnetic valve.
On described trachea, the external diameter of tubule is not more than the internal diameter of extra heavy pipe.
On described trachea, the surface roughness of extra heavy pipe inwall is 0.4 μm～0.5 μm, the surface roughness of extra heavy pipe inwall
Surface roughness higher than thin tube inner wall.
Described piston adopts resistant to elevated temperatures ceramic material, and the diameter of piston outer wall is equal to the diameter of extra heavy pipe inwall.
The beneficial effects of the present invention is：Its structure is simple, installs heat-insulated resistant to elevated temperatures Ceramic piston interior, realizes pressure
The isolation of expellant gas in sensor and casting mould, thus effective protection pressure transducer.
Brief description：
Fig. 1 is the structural representation of the present invention.
In figure：1st, trachea；11st, tubule；12nd, extra heavy pipe；2nd, cover；3rd, pressure transducer；4th, piston；5th, relief tube；6th, electricity

Specific embodiment：
Embodiment：As shown in Figure 1, the sensor construction on a kind of BGA stannum ball forming device, casts including with BGA stannum ball
The trachea 1 that vent bore is connected, trachea 1 is made up of the tubule 11 of bottom and the extra heavy pipe 12 on top, and the top of extra heavy pipe 12 is solid
Surely there is capping 2, capping 2 is fixed with pressure transducer 3, the probe of pressure transducer 3 is plugged in extra heavy pipe 12, extra heavy pipe 12 interpolation
It is connected to piston 4, piston 4 is resisted against the top of tubule 11, grafting on described tubule 11 is fixed with relief tube 5, solid on relief tube 5
Surely it is connected with electromagnetic valve 6.
On described trachea 1, the external diameter of tubule 11 is not more than the internal diameter of extra heavy pipe 12.
On described trachea 1, the surface roughness of extra heavy pipe 12 inwall is 0.4 μm～0.5 μm, the surface of extra heavy pipe 12 inwall
Roughness is higher than the surface roughness of tubule 11 inwall.
Described piston 4 adopts resistant to elevated temperatures ceramic material, and the diameter of piston 4 outer wall is equal to the diameter of extra heavy pipe 12 inwall.
Operation principle：The present invention is the sensor construction on BGA stannum ball forming device, particularly with regard to the protection for sensor
Structure, it installs heat-insulated resistant to elevated temperatures Ceramic piston 4, then mould in the tracheal strips being connected with BGA stannum ball shaping mould steam vent
Expellant gas enter compression in the tubule 11 of trachea 1, the gas meeting jack-up piston 4 of compression, change piston 4 upside extra heavy pipe 12
Pressure, thus pressure transducer 3 avoids in the directly contact of mould expellant gas, enables to detect, when it simultaneously again
To after certain limit, then just triggering BGA stannum ball shaping mould stops conveying tin liquor, electromagnetism simultaneously to the value of pressure transducer 3 detection
Valve 6 is opened and is laid down a pressure, it is to avoid in trachea 1, compression flows back in mould.
