Abstract
The invention discloses a surface processing method of a printing template, and relates to the technical field of printing equipment production. The surface processing method comprises four process steps including surface cleaning, polishing, oil removing and heating drying. The surface processing method has the advantages that multiple processes are adopted, and uneven positions and burrs and impurities remained on the surface of the printing template can be removed, so that the printing template with the flat and smooth surface is obtained; through reasonably selecting each ingredient of oil removing liquid and matching the reasonable recipe, the oil removing efficiency of an oil removing work procedure is high, the whole technological process is simple, the operability is high, and the automation production can be easily realized.
Description
Technical field
The present invention relates to printing equipment production technical field, be specifically related to a kind of method of surface finish of printing stencil.
Background technology
Along with high-tech high speed development, the very large application that laser cutting technique obtains in all trades and professions.In SMT electronic product industry, original silk screen plate mode of printing precision is low, molding effect is poor, and the shortcoming such as not to be durable, in order to semiconductor and electronic product requirements at the higher level can be met, be widely used the sheet metal hollowed printing template of laser cutting, for the mould printing in surface mounting technology.Laser cut stencil is the small light beam sent by high-power laser equipment, focus is formed after line focus, focus produces high temperature to metal form local melting, by continuous print light beam and compressed air, it is cooled in time, drive metal form to make orbiting motion by motion again, just define mesh template.Its advantage is that template opening becomes geometry trapezoidal, and be used in tin cream and roll and the demoulding, product Aperture precision is high, and opening flexibility is larger but also durable in use etc.Its shortcoming is metallic plate after laser cutting because a little irregular slag of the following adhesion of billet necking after hot melt cutting (is called for short steel billet burr; also burr is); laser local when cutting metal template is also had to produce high temperature; and guarantee cutting accuracy to be cooled in time to it; and meeting and compressed air produce oxidation and forms the very thin black oxide coating (also making oxidation burn) of one deck on the metal surface during metal form cooling, these all can make template be unfavorable for printing the demoulding or printing effect difference etc. at printing process.
Summary of the invention
Problem to be solved by this invention is to provide the method for surface finish of simple, the practical printing stencil of a kind of processing method.
To achieve these goals, the technical scheme that the present invention takes for: the method for surface finish of a kind of printing stencil provided, comprises the steps:
(1) surface clean: cleaned by printing stencil distilled water, removes the impurity of remained on surface;
(2) polishing: by cleaning after printing stencil put in sand-blasting machine, and on two sides even sandblasting 21-25min, remove the black oxide coating on its surface;
(3) oil removing: be immersed in degreasing fluid by the printing stencil after polishing, and clean it with ultrasonic wave, finally rinses with distilled water;
(4) heating, drying: to be cleaned complete after, put in drying box by printing stencil and heat 20-30min, control heating-up temperature is 60-70 DEG C.
Preferably, the degreasing fluid in described step (2) is the mixed solution of acid dimethyl sodium, alkyl benzene sulphonate, diethanol amine and tetrapotassium pyrophosphate composition.
Preferably, in described degreasing fluid, the mass ratio of acid dimethyl sodium, alkyl benzene sulphonate, diethanol amine and tetrapotassium pyrophosphate is 5:20:7.2:120.
Adopt technical scheme of the present invention, by adopting multiple tracks technique, the impurity of printing stencil remained on surface and irregular position and burr can be removed, obtain surfacing, smooth printing stencil, be equipped with rational formula by each component of choose reasonable degreasing fluid, make the oil removal efficiency of oil removing operation high, whole technical process is simple, workable, easily realize automated production.
Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
embodiment 1:
(1) surface clean: cleaned by printing stencil distilled water, removes the impurity of remained on surface;
(2) polishing: by cleaning after printing stencil put in sand-blasting machine, and on two sides even sandblasting 23min, remove the black oxide coating on its surface;
(3) oil removing: be immersed in degreasing fluid by the printing stencil after polishing, and clean it with ultrasonic wave, finally rinses with distilled water;
(4) heating, drying: to be cleaned complete after, printing stencil is put in drying box and heats 22min, control heating-up temperature be 65 DEG C.
In the present embodiment, degreasing fluid is the mixed solution of acid dimethyl sodium, alkyl benzene sulphonate, diethanol amine and tetrapotassium pyrophosphate composition, and in described degreasing fluid, the mass ratio of acid dimethyl sodium, alkyl benzene sulphonate, diethanol amine and tetrapotassium pyrophosphate is 5:20:7.2:120.
Based on above-mentioned, by adopting multiple tracks technique, the impurity of printing stencil remained on surface and irregular position and burr can be removed, obtain surfacing, smooth printing stencil, be equipped with rational formula by each component of choose reasonable degreasing fluid, make the oil removal efficiency of oil removing operation high, whole technical process is simple, workable, easily realize automated production.
Obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
Claims (3)
