Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the utility model is described in further detail.
PCBA off-line cleaning machine schematic perspective view such as Fig. 1-3 of the present utility model: mainly include that main frame body 1, pipeline 2, control panel 3, purge chamber 4, exhaust outlet 5, liquid reserve tank 7, cleaning device of jig 17, filter 6, proportioning pump 20, electric cabinet 18, deionized water process recovery system 54 (DI water processes recovery system), clean pump 31, rinsing pump 32.
As shown in Figure 1, 2, on control panel 3, table has: pressure when cleaning pressure table 13 display is cleaned, pressure during rinsing Pressure gauge 14 display rinsing, bleed pressure table 15 shows that bleed pressure, touch-screen 12, key switch button 9, alarm 8, emergency stop push button 10, resistivity table 11 detect quality of de-ionized water.
Such as Fig. 7, liquid reserve tank 7 mainly includes dilution case 23, rinsing liquid case 22, stoste case 24(cleaning fluid tank), liquid distributing device 26, agitating device 25 and heat-generating pipe 27.
Mainly introduce double pump system of the present utility model, deionized water returns processing system and tool spray equipment.
nullAs shown in Figure 4，Double pump system: double pump system described in the utility model i.e. includes two vertical pumps (cleaning pump 31 and rinsing pump 32)、Purge chamber 4、Spray boom 30、Liquid reserve tank 7、Angle pedestal valve 28、Agitating device 25，Clean during cleaning pump 31 cleaning fluid in dilution case 23 is released enter distribution nozzles on spray boom 30(spray boom through filter) produce pressure and be ejected into product surface by nozzle and carry out high-pressure wash，Cleaning fluid after cleaning is back to dilution case 23 when purged through liquid distributing device 26(，Rinsing liquid case 22 it is back to during rinsing) it is back to stoste case 24(cleaning fluid tank)，Iterative cycles cleans，Cleaning rinses after completing，Clean pump 31 to quit work，Enter rinse stage，Rinsing is divided into just drift and essence two stages of drift，Just drift and essence drift are all worked by rinsing pump 32，Just during drift, rinsing liquid (deionized water) extraction in rinsing liquid case 22 is arrived spray boom 30 through filter unit 34 and produces pressure by rinsing pump 32，It is ejected into product surface by nozzle to be carried out，Deionized water after cleaning is through liquid distributing device 26(part flow arrangement) it is back to rinsing liquid case，So iterative cycles cleans，After just having rinsed，Deionized water in rinsing liquid case 22 is retracted to deionized water recovery and processing system 54(and separately describes in detail by membrane pump 55) process，Rinsing liquid case 22 again fills up new deionized water and opens essence drift such as，Essence rinse cycle is the same with first rinse cycle.
As shown in Figure 5, DI water treatment system (deionized water water treatment system 54): deionized water processing system 54 is made up of filtering frame 35, filter pump 40, Rose Box the 42, first filter vat the 37, second filter vat 39, sewage draining exit 38, its course of work is: the deionized water in rinsing liquid case 22 is extracted into the first filter vat 37(quartz sand by membrane pump 55) inner filter after again through the second filter vat 39(activated carbon) filter, store subsequently into Rose Box 42, being retracted to rinsing liquid case 22 by filter pump 40 again and be used as rinsing use, such circulating filtration utilizes.Equipped with liquid level safe inductive device 43 and liquid level window 41 in its Rose Box 42, when liquid level is higher than safety levels, electrodynamic pump can be drained (because rinsing is divided into first rinsing and essence two stages of rinsing automatically, being the deionized water using filtration cycle the most for the first time, essence rinsing is by external deionized water).
nullAs shown in Figure 6，Tool spray equipment: tool spray equipment includes pulley 44、Inlet 45、Tool frame 46、Shower 47、Product 48(needs cleaning)，Its machine cleaning process includes、Lower spray and level two stages of spray，On、It is upper that lower vertically spray is distributed across in purge chamber、In、Lower three spray booms 30 become，Level spray is to complete (as shown in Figure 3) by tool shower 47，Product is placed on tool (tool frame 46)，Tool frame 46 is to be welded by hollow stainless steel square tube，Its internal each branch road communicates mutually，Form a closed loop，Liquid is the most capable of circulation，During level spray，The valve body of control level spray is opened，Liquid enters tool frame 46 from inlet 45 and produces the big pressure of tool，Spray highly pressurised liquid from tool shower 47 to produce mouth both sides and carry out high pressure to cleaning and strafe the small pin hole of spray (be distributed tool shower 47)，Liquid after spray returns liquid reserve tank 7，So iterative cycles.
As shown in Figure 8, equipped with pure cleaning fluid inside stoste case 24, the lower end of proportioning pump 20 is connected with stoste case 24 by pipeline 56, other end entrance exports (water out that deionized water processes recovery system 54) and is connected with deionized water, cleaning fluid and deionized water mix (its ratio manually regulates) by certain proportion in proportioning pump, and mixed diluent liquid is input to dilution case 23 by pipeline.nullClean pump 31 during cleaning and the liquid extraction in dilution case 23 is input to spray boom 30 after filter filters，Produce high pressure，It is ejected into PCBA surface by nozzle to be carried out，It is back to dilution case 23 when cleaning fluid after cleaning is by liquid distributing device 26(cleaning fluid，Rinsing is back to rinsing liquid case 28) it is back to dilution case 23，So circulation is carried out，Clean and terminate post rinse pump 32 and start working to extract the deionized water in rinsing liquid case 22 out and after filter unit 34 filters, be input to spray boom 30 by pipeline produce high pressure，It is ejected into PCBA surface through nozzle to rinse for the first time，Deionized water in rinsing liquid case 22 is retracted to deionized water recovery system 54 by first rinsing end metacneme pump 50 to be carried out filtering (pipeline 49 is the signal of turnover direction)，After filtration, storage is to deionized water Rose Box 42.External deionized water is filled into rinsing liquid case 22, and rinsing pump is again started up that through filter to spray boom 30, the deionized water extraction in rinsing liquid case is produced high pressure and carries out essence rinsing through nozzle injection table PCBA surface.After essence rinsing terminates, deionized water in rinsing liquid case 22 is retracted to deionized water filter and filters storage to deionized water Rose Box 42 by membrane pump 50, unnecessary deionized water is drained through deionized water discharge outlet, and filter pump 40 starts and the deionized water in deionized water Rose Box 42 is retracted to rinsing liquid case 22 is used as first rinsing next time simultaneously；Hot blast in hot bellows is blown to that purge chamber 4 is inner dries product by fan starting simultaneously.
Above content is to combine specific embodiment further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
