Abstract
The invention discloses a pre-encapsulation LED module dust blowing method and device. The pre-encapsulation LED module dust blowing method comprises putting a product to be dedusted on a stainless steel net plate of a dedusting device and utilizing a blower gun to blow dust on the surface of the product away form the surface of the product, so that sundries of relatively large particles fall into a dust collecting box under the action of gravity, tiny dust is exhausted outdoors along with wind and second dust pollution caused by return of dust to a production environment can be avoided. According to the pre-encapsulation LED module dust blowing method and device, the professional dust blowing device is manufactured through principles of combination of positive pressure airflow and negative pressure airflow, absolute separation of the dust blown away from the product from the product is achieved, and the technical problem that floating dust leads to secondary product pollution can be solved. Circular production of the floating dust can be eliminated, accordingly, product quality and the rate of finished products of the whole production line can be improved, a workload of a floating dust detection working procedure is reduced, and subsequent machining of the product and raw material costs can be reduced. Through practical application, the dedusting effect is significant, the technology is mature, and the reliability is high and certain popularization and application values can be obtained.

there is no at present professional drifting dust equipment, is directly dot matrix member and shell to be placed on platform and to carry out drifting dust processing with compressed air.Blow afloat the dust coming and be suspended in the air, these suspended dusts can become secondary pollution source, cannot meet the quality of product and the requirement of production technology environment.
Summary of the invention
the object of the invention is to, drifting dust method and device before a kind of LED module embedding are provided.Can prevent secondary pollution, guarantee product quality.To overcome the deficiencies in the prior art.
technical scheme of the present invention:
a kind of drifting dust method before LED module embedding, the method is that the product for the treatment of dedusting is placed on the stainless (steel) wire dish of dust arrester, utilize air pressure gun by the dust of the product surface product surface that blows off, the foreign material of larger particles fall under gravity into dust collecting box, trickle dust is with outside the discharge chamber of air channel, avoids dust to come back to and in production environment, causes secondary dust pollution.
in aforementioned drifting dust method, described air pressure gun adopts ion wind gun, forms high flow rate ion wind by high pressure ionization, and the electrostatic adsorption of elimination product surface makes the dust of the product surface product surface that more easily blows off.
in aforementioned drifting dust method, described air channel is connected with axial flow blower, utilizes axial flow blower near product, to cause negative pressuren zone, and the dust of the product surface that makes to blow off, outside the discharge chamber of air channel, avoids causing secondary dust pollution.
the device forming according to preceding method, comprises ion wind gun and frame, and frame is provided with stainless (steel) wire dish, and stainless (steel) wire dish below is provided with funnel, and funnel bottom is connected with dust collecting box; The frame of stainless (steel) wire dish rear side is provided with suction port, and suction port is connected with air channel with funnel.
in aforementioned means, described ion wind gun is connected with ion generator and compression gas pipe.
in aforementioned means, described air channel is connected with axial flow blower.
in aforementioned means, described dust collecting box is drawer type dust collecting box.
compared with prior art, the principle that the breakthrough employing positive/negative-pressure air-flow of method of the present invention combines is made professional drifting dust equipment, the dust of the product that blows off and product have been carried out separating thoroughly, and the floating dust that has solved the generation of drifting dust process causes the technical barrier of secondary pollution to product.Thereby improve the yield rate of product quality and whole production line, broken away from the circulation generation of floating dust, and reduced the workload of floating dust detection operation, post-production cost and the cost of raw material of LED module product are reduced.The present invention is through practical application, and dust removing effects is remarkable, technology maturation, and reliability is high, has certain application value.
