Dispenser system, it comprises pneumatic mechanism and point tin cream syringe needle, and point tin cream syringe needle is connected with pneumatic mechanism, and pneumatic mechanism is passed with straight drive
Dynamic system connects, and straight drive and transmission system connects to control system.
As a further improvement on the present invention；Described point tin cream syringe needle is fabricated to list for high-strength stainless steel alloy material
PIN or many PIN integrated-type Glue dripping head, solder(ing) paste is accurately transported to workpiece to be welded by point tin cream syringe needle（Components and parts PIN
Pin and pcb board or soft base plate pad）On, single needle syringe needle can be put tin cream one by one to components and parts PIN；Spininess syringe needle is permissible
Tin cream is disposably put to all PIN of components and parts.
As a further improvement on the present invention；The critical piece of described pneumatic mechanism is cylinder, by air pressure, will put tin
Cream syringe needle smooth transportation to the specified location of workpiece to be welded, and by solder(ing) paste point on workpiece to be welded.
As a further improvement on the present invention；Described straight drive and transmission system is elaborate servo Zhi Qu mechanism, comprises servo
Controller, X-axis servomotor, Y-axis servomotor, X-axis servomotor, Y-axis servomotor are all by servo controller and control
System connects.High-accuracy ultra micro dispenser system is delivered directly to workpiece specified location to be welded, then completes a tin cream technique.
As a further improvement on the present invention；It is master controller that described control system adopts PLC, and Main Function is to coordinate
Pneumatic mechanism and the accurate operation of straight drive and transmission system, are precisely controlled a tin cream syringe needle and go out the amount of tin cream and the position putting tin cream,
For the later stage, the disposable welding procedure of execution is ready.
The principle of the present invention is：
After system starts, ventilation pressurization first, during a tin cream, straight drive and transmission system works first, by high-accuracy ultra micro
Dispenser system is transported to specified location, and then pneumatic mechanism is started working, and allows a tin cream syringe needle smooth near components and parts PIN,
When a tin cream syringe needle reaches the point tin position specified, by control system adjustment air pressure, put tin cream syringe needle output solder(ing) paste, etc.
After the solder(ing) paste of point tin cream syringe needle output is attached on components and parts PIN to be welded and pcb board or soft base plate pad, it is shut off gas
Motivation structure, allows a tin cream syringe needle away from the PIN of components and parts to be welded, end point tin cream technique.
After technique scheme, the invention has the advantages that：
Single PIN and many PIN integrated-type Glue dripping head are fabricated to using high-strength stainless steel alloy material（For a tin cream）, its
Excellent guide performance, the accurate control of cooperation pressure and time so that disposably point tin cream qualification rate more than 98% with
On, and greatly improve a tin cream efficiency and point tin cream quality, and use cooperatively with graphite material integrated-type superconduction plumb joint, permissible
Reach preferable welding efficiency and welding effect.
