The present invention utilizes the cleaning fluid of aqua type to carry out Chemical cleaning, the harmful pollution such as the welding assisted agent residuals on support plate surface, soldering paste, tin ball, impurity, dust, oil stain are removed, DI water is used to carry out rinsing and last oven dry, crystal covered carrier-board is made to reach the cleanliness factor of 100%, without any potential safety hazard, and to human body and environment fanout free region.First the present invention performs Chemical cleaning, this process generally adopts aqua type cleaning fluid, added by outside, must be heated liquid by heater before washing and cleaning operation, to strengthen cleansing power, through the aqua type cleaning fluid of heating, sucked by high pressure pumping and produce higher pressure, liquid enters each nozzle by pipeline, and ejected by nozzle, forming fan water curtain impacts on crystal covered carrier-board surface, when hydraulic shock crystal covered carrier-board surface, with the material generation physical reactions on plate surface, the pressure that liquid produces and physical reactions ability can by the tin creams on crystal covered carrier-board surface, rosin, scaling powder and pollutant are peeled off, clean by multiple nozzle is staggered, the all substances in crystal covered carrier-board face are all peeled off totally, thus reach the object of Chemical cleaning.And the pollutant after peeling off is filtered out through filter, cleaning fluid is recycled, extends the life cycle of cleaning fluid simultaneously, and this based cleaning liquid surfactant-free and the formula without solid, do not have residue after making cleaning part drying.The active ingredient in solution will be caused to reduce and the lost of life gradually because of the permanent combination of abutment surface activating agent and pollutant, safe and reliable after cleaning.
Chemical isolation is the chemical liquid gone out by Chemical cleaning length of tape by crystal covered carrier-board, and the high pressure wind-force utilizing high pressure blower to produce, isolates it through air knife.Liquid backflow after isolation is to cleaning fluid tank.Object reduces the consumption of liquid, reduces the difficulty of back segment cleaning; Pre-rinsing be utilize DI water rinse Duan Yi to reserve addle as rinsing liquid, to the first rinsing of the chemical substance of the crystal covered carrier-board remained on surface after chemical isolation, stayed the rinsing liquid of case to suck by high pressure pumping by overflowing and produce higher pressure, liquid enters each nozzle by pipeline, liquid is ejected by nozzle, and form the impact of fan water curtain on crystal covered carrier-board surface, when hydraulic shock crystal covered carrier-board surface, the chemical substance on crystal covered carrier-board surface is peeled off, object reduces the difficulty of back segment rinsing, and cleaned DI water is directly drained.
DI water rinse adopts DI water as rinsing liquid, added by external pipe, to the chemical substance of the crystal covered carrier-board remained on surface after pre-rinsing in secondary rinsing, must be heated rinsing liquid by heater before rinse operation, to strengthen rinse capacity, through the rinsing liquid of heating, sucked by high pressure pumping and produce higher pressure, liquid enters each nozzle by pipeline, liquid is ejected by nozzle, and form the impact of fan water curtain on crystal covered carrier-board surface, clean by multiple nozzle is staggered, the all substances in crystal covered carrier-board face are all peeled off, reach the object of rinsing, and this process rinsing liquid recycles, and have relief function, the material that proportion is more clear in rinse cycle can swim in the water surface, flow to overflow by overfall and stay case, to reduce the pollution of chemical substance to rinse tank liquid.
Spray be utilize water treatment facilities to produce DI water as rinsing liquid, the resistance value of DI water is very high, more than 10M can be reached, its ion concentration is in cleaning industry prescribed limit, pure DI water is used to carry out last rinsing to the pcb board surface after DI water rinse section, DI water is accessed by external pipe and keeps corresponding pressure, DI water enters each nozzle by pipeline, liquid is ejected by nozzle, and form the impact of fan water curtain on crystal covered carrier-board surface, when hydraulic shock crystal covered carrier-board surface, all chemical substances on crystal covered carrier-board surface are peeled off clean, reach 100% cleaning, rinsed DI water is back to rinse tank, object saves the consumption of water.
In addition, the concrete on-link mode (OLM) of rubber roll transmission is linear contact lay, reducing contact area can make cleaning more abundant, product transmits between upper lower rubber roller, the gap of upper lower rubber roller is very little, only hold product to pass through in centre, therefore can keep the stability of product in the middle of the process of Transmission, and cause bob when substrate can not be caused to be cleaned or through air knife time.
What cleaning section nozzle was selected is that big-flow high-pressure power mode is cleaned, and be rinsed into DI water rinse section in advance little with narrow angle-style fan nozzle flow, pressure is high, and last spray phase uses outside DI water, and resistivity is high as last wash phase.
Cleaning fluid tank and rinsing water outlet of water tank are all provided with high pressure and are provided with liquid pump, are all provided with screen pack (precision 2*2mm) in filter (precision 5 μm) casing.
More than that crystal covered carrier-board on-line cleaning machine provided by the present invention is described in detail, apply specific case herein to set forth structural principle of the present invention and embodiment, above embodiment just understands method of the present invention and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, to sum up, this description should not be construed as limitation of the present invention.
