Description
Technical field
The present invention relates to the packaging technology of power model, particularly a kind of automatic glue filling machine being applicable to power module package technique.
Technical background
In electron trade, particularly micropower modular power source, portioned product realizes encapsulation by encapsulating, because of environment for use and the performance requirement of product, also has corresponding requirement to the state of cure of glue.
As shown in Figure 1, for the control principle schematic diagram of existing glue pouring machine, a kind of glue pouring machine, for exporting casting glue by after host and curing agent mixing, comprise the defeated colloid system of the master of host 10 is provided, the auxiliary defeated colloid system 20 of curing agent is provided, be main defeated colloid system and auxiliary defeated colloid system carry out vacuumizing vacuumize motor 30 and mixing valve 50, main defeated colloid system 10 comprises basic material barrel 11, be located at main outlet valve 12, main metering pump 15 below basic material barrel, drive the mair motor 17 of main metering pump and be connected to the main glue conveying box 19 of mixing valve from basic material barrel; Auxiliary defeated colloid system 20 comprises auxiliary material bucket 21, be located at auxiliary outlet valve 22 below auxiliary material bucket, auxiliary measuring pump 25, drive the auxiliary motor 27 of auxiliary measuring pump and be connected to the auxiliary glue conveying box 29 of mixing valve from auxiliary material bucket.Wherein, casting glue is electron pouring sealant, is usually mixed by host and curing agent, and host is often called A agent; Curing agent is often called B agent.Mixing valve is the device that fluid chemical field Hou Jing mono-tunnel flowed into by two-way is flowed out.
Along with small product size is more and more miniaturized, more and more higher to the distributing precision of automatic glue filling machine, plastic emitting required precision, particularly totally enclosed type modular power source, load onto lid after encapsulating to solidify again, the solidification situation of interiors of products glue cannot be learnt, prior art cannot detect the situation after products solidifying again automatically, then can only monitor at encapsulating end, guarantees that the proportioning of automatic glue filling machine is normal constantly.But the defeated colloid system of existing automatic glue filling machine is mostly without flow monitoring, in encapsulating operating process because of factors often there will be that flow is forbidden, human operational error and occur that product encapsulating is not done, cause product to be scrapped in enormous quantities or customer complaint problem.
Summary of the invention
After the existing glue pouring machine of application meets with the puzzlement for a good while of prior art problem, inventor conducts in-depth research specially to this.
After its structural analysis is had no result, inventor then analysed in depth the dosing technology process of product, though find that existing automatic glue filling machine has measuring pump to carry out the ratio regulation and control of feed flow, but owing to only adopting opened loop control, and do not consider the interference that external factor causes, cause product embedding Post RDBMS not thorough.Further careful analysis finds, occurs that glue is not dry and mainly contains following reason:
1, curing agent storage vat in use needs inwardly to fill nitrogen, play isolated air and pressurization, so that curing agent is sustainable, transfer pump output accurately, along with the minimizing of curing agent in storage vat, in bucket, atmospheric pressure also decreases, and when in bucket during atmospheric pressure≤external atmospheric pressure, the curing agent dosage of transfer pump reduces maybe cannot flow to pump end, cause flow adhesive to be forbidden, impact is participated in the real-time proportioning of host and the curing agent mixed and occurs that glue is not done further.
2, there is a manually-operated gate automatic glue filling machine storage vat lower end, and manually must close this valve when vacuumizing, as forgotten valve-off, then the glue in glue conveying box road can be drawn back storage vat, and Guan Zhonghui enters air impact flow and then affects proportioning; Must opening this valve when operation, opening valve as forgotten, the output glue that pump will continue is uniformly mixed to mixing end.
3, when measuring pump occurs that mechanical faults causes holddown, deviation appears in the pulse that provides the motor of pump power to accept, although measuring pump is still at " continuing ", " stablizing " ground feed, but the dosage off-design proportioning required dosage of material, cause flow adhesive to be forbidden, impact is participated in the real-time proportioning of host and the curing agent mixed and occurs that glue is not done further.
4, glue conveying box road occurs that distortion, pipe joint omission etc. all can cause flow adhesive to be forbidden, and affects real-time proportioning further and occurs that glue is not done.Most importantly, although there is the ratio feed that main and auxiliary measuring pump provides lasting, in theory, the host of glue and the design proportioning of curing agent should be secure.But because the host of glue compares thickness, curing agent is rarer, both are in the hybrid chamber of glue conveying box and mixing valve, suffered fluid pressure difference is very large, and the proportioning usage variance of host and curing agent is larger, in addition the effect of mixing valve power, make auxiliary glue conveying box, in hybrid chamber, fluid pressure becomes very complicated, as easy as rolling off a logly cause the fluid pressure in hybrid chamber and auxiliary glue conveying box unbalance, the flow regime of curing agent in auxiliary glue conveying box is caused to be failed to understand, and then make the curing agent in auxiliary glue conveying box be difficult to enter hybrid chamber by design proportion, thus cause host and curing agent to continue to occur that proportioning is forbidden within long period of time, and to be difficult to discover by people.
Due to all detailed problem of fluid in glue pouring machine in real-time flowing transmitting procedure to be difficult to be familiar with by people and find, all fail to making the prior art of glue pouring machine to make corresponding improvement for these problems, and then make the quality problems such as the solidification of modularization embedding series products is thorough, glue is dry can not get for a long time solving up hill and dale.
In view of this, the technical problem to be solved in the present invention be to provide that a kind of proportioning improving automatic glue filling machine is abnormal, operate miss time cannot Timeliness coverage and cause the glue pouring machine of product exception in enormous quantities or customer complaint problem.
For solving the problems of the technologies described above, be applicable to the flow of the defeated colloid system of automatic glue filling machine, the monitoring of pressure, and fundamentally solve proportioning that existing automatic glue filling machine often occurs not to and cause glue dry to such an extent as to the product problem that occurs customer complaint or scrap, the invention provides following technical scheme
