Abstract
The invention relates to the technical field of surface treatment of a plastic part, in particular to a surface cleaning method for the plastic part for cleaning a plastic mobile phone shell. The surface cleaning method comprises the following steps: firstly, the plastic part is assembled on a work rest and arranged inside vacuum plating furnace equipment; secondly, the vacuum plating furnace equipment is subjected to vacuum pumping; thirdly, argon gas is filled in the vacuum plating furnace equipment; and fourthly, a negative supply is switched on, wherein the argon gas is filled in the vacuum plating furnace equipment, so that an ion emission source on the vacuum plating furnace equipment generates argon ions which bombard the surface of the plastic part under a vacuum environment. The surface cleaning method for the plastic part has the advantages of reducing the equipment cost, improving the production efficiency, guaranteeing the product quality and improving the surface cleanliness.
Description
Technical field:
The present invention relates to the plastic rubber member surface processing technology field, more specifically to a kind of plastic rubber member surface cleaning method.
Background technology:
Plastic cellphone casing texture is good, and wear resistance is good, and cost is lower, therefore is used for mobile phone products in a large number.Plastic cellphone casing all will clean in that plated film is forward and backward, so that improve the quality of products.
At present, traditional cleaning method is, adopt ultrasonic cleaning apparatus to clean, the principle of work of this ultrasonic cleaning apparatus is, the high-frequency oscillation signal that sends by ultrasonic generator, converting the high frequency mechanical oscillation to by transverter propagates in medium-cleaning solvent, ultrasonic wave in scavenging solution density interphase ground to previous irradiation, make liquid-flow and produce the micro-bubble that ten hundreds of diameters is 50-500 μ m, these bubbles form at the negative pressuren zone of ultrasonic wave longitudinal propagation, growth, and at the zone of positive pressure rapid closing, in this process, the bubble closure can form the high temperature of several Baidu and surpass the instantaneous pressure of 1000 air pressure, continuously produce instantaneous pressure, resemble a succession of little " blast " and constantly impact article surface, the surface of object and the dirt in the slit are peeled off rapidly, thereby reach the purpose of article surface cleaning.Adopt the shortcoming of this method to be, ultrasonic cleaning apparatus cost height takes up an area of extensively, and easy residual moisture content influences product quality.
Also have a kind of traditional cleaning method, promptly manual the wiping tried, and utilizes by hand plastic cellphone casing is carried out wiped clean.Adopt the shortcoming of this method to be, need to drop into great amount of manpower, and efficient is low, cleaning effect is bad, the product quality instability.
Summary of the invention:
The objective of the invention is at the deficiencies in the prior art, a kind of plastic rubber member surface cleaning method is provided, this method can reduce equipment cost, enhances productivity, guarantees product quality, improve surface cleanliness.
For achieving the above object, the present invention is achieved by the following technical solutions: plastic rubber member surface cleaning method, and it may further comprise the steps:
The first step is assembled into plastic parts on the work rest, in the vacuum of packing into the plating furnace apparatus;
In second step, vacuumize in the vacuum plating furnace apparatus;
In the 3rd step, inject argon gas in the vacuum plating furnace apparatus;
The 4th step, open negative supply, inject argon gas in the vacuum plating furnace apparatus, make the emission of ions source on the vacuum plating furnace apparatus produce argon ion, argon ion is high-energy bombardment plastic rubber member surface under vacuum environment.
In described second step, the vacuum tightness after vacuumizing in the vacuum plating furnace apparatus is 2.0 * 10
-2Pa.
In described the 3rd step, the argon gas injection rate is 50～300ml.
In described the 4th step, the time of argon ion bombardment plastic rubber member surface is 3～5min.
In described the 4th step, the argon gas injection rate is 50～200ml/min.
In described the 4th step, the operating voltage in emission of ions source is 250Ua * 10Ua, and working current is 0.3A ± 0.1A.
Beneficial effect of the present invention: the present invention only needs to increase a cover emission of ions source device on vacuum plating furnace apparatus basis, utilize argon gas under the agitating in emission of ions source, produce argon ion, argon ion carries out surface physics bombardment and chemical reaction to plastic rubber member surface, make plastic rubber member surface generation activation, thereby reach the purpose of removing surface blot, therefore, this plastic rubber member surface cleaning method has and reduces equipment cost, enhances productivity, guarantees product quality, improves the advantage of surface cleanliness.
Embodiment:

Second step, use vacuum extractor to vacuumizing in the vacuum plating furnace apparatus, making vacuum tightness is 2.0 * 10
-2Pa;
The 3rd step, inject argon gas in the vacuum plating furnace apparatus, making the argon gas injection rate is 50～300ml;
The 4th step, open negative supply, negative supply starts the emission of ions source on the vacuum plating furnace apparatus, the emission of ions source produces argon ion, the operating voltage in emission of ions source is 250Ua * 10Ua, working current is 0.3A ± 0.1A, and argon ion is high-energy bombardment plastic rubber member surface under vacuum environment, and the time of argon ion bombardment plastic rubber member surface is 3～5min; In the time of bombardment, inject argon gas in the vacuum plating furnace apparatus, the argon gas injection rate is 50～200ml/min, meets the demands with the concentration that guarantees argon gas in the vacuum plating furnace apparatus.
Argon gas is under the agitating in emission of ions source, produce argon ion, argon ion carries out surface physics bombardment and chemical reaction to plastic rubber member surface, make plastic rubber member surface generation activation, thereby reach the purpose of removing surface blot, therefore, this plastic rubber member surface cleaning method has and reduces equipment cost, enhances productivity, guarantees product quality, improves the advantage of surface cleanliness.
The above only is preferred embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
