Description
Technical field
The present invention relates to dispensing field is sprayed, more particularly to a kind of ejecting adhesive dispenser.
Background technology
The characteristics of injection dispensing technology has noncontact and high-speed and high-efficiency, is that the microelectronic packaging technology field next generation is emerging
Fluid dispensing technology.It is either external or domestic, all to spraying dispensing Technical investment substantial amounts of theoretical research and practice
Inspection, have accumulated substantial amounts of theoretical result and technical experience, and many is also had been put into based on the product facility of injection dispensing technology
Manufacture industry.Colliding between glue drop and substrate, drop and drop makes drop deformation and splashing, and it deforms and flies
The degree direct influence splashed is to bond quality for dispensing glue and forming accuracy, and is splashed to the device of surrounding, to operating point week
The device for enclosing is polluted, or even the device around damaging.So, for problem during injection glue droplet collision for dispensing glue
Research and solution, be beneficial to improve injection dispensing technology, improve injection quality for dispensing glue and concordance.Glue drop and base
The drop deformation produced because of collision between plate, drop and drop and splashing, are mainly manifested in：The continuous spray of ejecting adhesive dispenser
During penetrating, the combination situation between glue drop and substrate, drop and drop is undesirable, is deformed and splashes, dispensing
Quality it is undesirable, not only reduce injection work efficiency for dispensing glue, and quality for dispensing glue and concordance are poor.Crash
The deformation produced when hitting and splashing, main influence factor has：1st, the speed of droplet collision：In drop viscosity and diameter phase
Deng under conditions of, with the increase of drop and collision with wall speed, kinetic energy during collision is bigger, collides the concussion of drop after wall
Amplitude also can be bigger, and reaching the stable cycle also can be longer.Therefore, under general environmental conditions, liquid drop speed is bigger, drop
Deformation extent can be higher, easily occur fluid spills the problems such as.2nd, liquid-drop diameter size：In the equal condition of droplet collision kinetic energy
Under, with the reduction of liquid-drop diameter, the viscous loss and surface energy of kinetic energy conversion are less in motor process, after droplet impact wall
Spreading coefficient will be bigger.Therefore, under conventional environmental condition, with the increase for sprawling degree of drop, drop is easier
The problems such as splashing.3rd, the viscosity of drop：In the collision process of drop, the viscosity of drop has very big to the form for colliding drop
Impact, viscosity is lower, and the surface tension of drop is less, less to the formalness controlling extent of drop, when colliding with substrate
The spray height of generation is higher, and splash phenomena becomes apparent from.Therefore, as injection dispensing technology is toward high speed, micro and gelatin viscosity
The wide direction of scope is developed, spray glue drop speed it is higher, volume is less and range of viscosities is bigger, the glue for producing therewith
Droplet collision deformation, the problem splashed can be increasingly severe, and so as to produce, dispensing concordance is poor, spray site colloid amount does not meet
The problems such as production requirement.
However, prior art is to measure and use precision to the droplet size that electronic pressure regulating valve sprays by mathematical model
Balance carry out comparison of weighing, and then adjust the size of colloidal droplets improving injection quality for dispensing glue and concordance.
The defect of prior art is that required instrument precision is high, big to the injection fixing fabric structure difficulty of glue, manufactures work
Skill has high demands, and technical operation is complicated, causes ejection efficiency to be greatly lowered.
The content of the invention
The embodiment of the invention discloses a kind of ejecting adhesive dispenser, will be sprayed by low pressure generating meanss and operating on low voltage case
Ambient pressure for dispensing glue is controlled to the most suitable working environment pressure value tested out in advance, effectively suppresses high speed, micro spray
The deformation caused when colliding between injection liquid drop and workpiece installation base plate wall, between drop and drop and the degree of splashing,
Injection quality for dispensing glue and concordance are effectively raised, the instrument precision solved needed for prior art is high, to glue
Injection fixing fabric structure difficulty is big, and manufacturing process has high demands, and technical operation is complicated, causes the technology that ejection efficiency is greatly lowered to be asked
