Description
The present invention relates in the production process in fields such as electronic component, household appliances, quantitatively discharge, supply with the liquid discharge device of various liquid such as bonding agent, paste soldering material, lubricating grease, coating, hot melt liquid, medicine, food.
Liquid discharge device is applied to various fields already, still, is accompanied by the demand of the little form height density assembling of electronic component in recent years, the technology that requires that the energy high accuracy is arranged and stably control the fluent material flow.
Be example with surface-mounted (SMT) field for example, in the high speed, microminiaturization, densification, high-gradeization of assembling and unmanned mighty torrent, the problem that liquid discharge device faces is summarized following points:
1. improve the precision of coating weight;
2. shortening efflux time;
3. reduce coating weight one time.
As traditional liquid discharge device, always be extensive use of the liquid discharge device of air pulsing mode as shown in figure 12, for example wait on the books and periodicals for No. 7 and introduced this technology at 1993 25 volumes of Japan's " automatic technology " magazine.Adopt the device for draining fluid of this mode, offer in the container 150 (cylinder) the quantitative air pulse that will supply with from the level pressure source, and will discharge from nozzle 151 with the corresponding a certain amount of fluid of pressure rising degree in the cylinder 150.
The device of above-mentioned as an alternative air pulsing mode has begun to use the liquid discharge device that is commonly referred to as eccentric shaft pump Moyno pump (Moyno Pomp), employing rotation displacement type now.Because this Moyno pump is done to move like the snake, so another name is also referred to as the snake pump, this technology has been done detailed introduction in " piping technology " in July, 85 of Japan in number first-class books and periodicals.Figure 11 shows an example of its structure.
In Figure 11, the 100th, main shaft (driving shaft), the 101st, ball bearing, the 102nd, the rotor of snake pump, the 103rd, stator the 104, the 105th, universal coupling is connected with connecting rod 106 and this connecting rod 106 rotor 102 with driving shaft 100.Rotor 102 cross sections are circular, and external screw thread is arranged, and the cross section in hole that is provided with the stator 103 of the internal thread corresponding with this external screw thread is Long Circle.Rotor 102 setting-ins are gone in the stator 103, rotor 102 is rotated in the eccentric shaft center, then rotor 102 moves up and down on stator 103 internal edges rotation limit.The fluid that is sealed between rotor 102 and the stator 103 moves by fissureless unlimited piston, is delivered to the discharge side continuously from the suction side.
But there are the following problems for the liquid discharge device of above-mentioned these modes.
1. the problem of the liquid discharge device of air pulsing mode:
(1) fluctuation of the discharge rate that causes because of the pulse of discharge pressing;
(2) fluctuation of the discharge rate that causes because of differential water pressures;
(3) because of changing the discharge rate that causes, liquid viscosity changes.
The phenomenon of above-mentioned (1) is short more at pipeline, efflux time shows remarkable more more in short-term.Therefore, taked to be configured such that the height of air pulsing becomes the measures such as stabilized loop of even usefulness.
The reason of above-mentioned (2) is, because the volume of cylinder internal pore portion 152 is because of the difference of fluid surplus H is different, so when supplying with a certain amount of gases at high pressure, the pressure intensity of variation in the space part 152 can have very big variation because of the difference of above-mentioned H.If liquid residue reduces, coating weight can occur and for example compare and reduce by about 50-60% such problem with maximum.Therefore, taked for example following measure, that is, discharged all tracer liquid surplus H at every turn, the time of adjusting pulse in view of the above is wide, so that the discharge quantitative change is even.
Above-mentioned (3) betide the occasion that its viscosity of material of for example containing a large amount of solvents changes in time.Therefore the countermeasure of taking is, with viscosity variation tendency programmed in computer of relative time axle, for example adjusts pulse width in advance, to revise the influence that viscosity changes.
At the measure of above-mentioned problem, no matter which all makes the control system that comprises computer complicate, and the very difficult variation that adapts to irregular environmental condition (temperature etc.), be not the solution of essence.
2. with the problem of the liquid discharge device of snake pump:
Occasion at the snake pump, because be fluid is encapsulated into the displacement type of also carrying in the seal cavity of a constant volume, so compare with the device for draining fluid of above-mentioned air pulsing mode, be not vulnerable to the influence of viscosity variation, pump discharge lateral load variation etc., have constant flow rate characteristics.But, thisly rotating the limit by rotor 102 in stator 103 internal edges and do reciprocating linear motion and obtain the pump of pump-absorb action, rotor 102 is cantilever support structure basically, stator 103 effect of bearing of supporting rotor 102 of also having held concurrently.Therefore, if for example rise or pump load increases and causes that discharging lateral pressure rises, then do not possess the motion that sufficient location keeps the rotor 102 of function and become unstable easily because of the rotating speed of main shaft 100.Consequently, the gap change between rotor 102 and the stator 103, the change of internal leakage amount, thereby have the problem of flow accuracy difference etc.In addition, because of decreasing the discharge characteristic that causes, the eccentric wear of stator 103, rotor 102 passes in time that to become also be a very big problem.Therefore, because with the snake pump as liquid discharge device and when having done root diameter little, because above-mentioned, the limit of accuracy of discharging total amount is at most ± and 10-20%.
In addition, if adaptation liquid discharge device ultra micro rill quantize (flow Q=10 for example
-5Cm
3/ sec is following) demand and when attempting for example root diameter being accomplished D=0.5mm φ is following, there is the traditional structure of intermetallic contact can produce between this rotor, stator because of the situations such as strain, skimming wear and breakage that rotor strength lowly causes, extremely difficult with its practical application.
