Abstract
The invention discloses a kind of film covering methods of television backboard, comprising the following steps: does substrate using metal substrate, cleans to substrate；Substrate side is not applied glue by applicator roll glue coating with groove, substrate in the region that groove covered；Film is pasted in substrate side, the region and film that glue is coated on substrate are pasted, and the region for being not coated with glue can not paste film.Coating technique of the invention is simple and ingenious, it chooses metal substrate and does substrate, according to linear speed and coating roller diameter, reasonable speed ratio parameter is set, substrate is set not apply glue on specific region, precise positioning, accuracy height, the region for being not coated with glue can not paste film, it is subsequent to be easy for cutting away this part film, and then keep base material part exposed, to form specific conductive region in television backboard.
Description
Technical field
The present invention relates to the film covering methods of film coated plate technical field more particularly to television backboard.
Background technique
Household electrical appliance at present, especially television backboard have conductive demand, VCM film coated plate warp in the specific region in part
It is completely nonconducting after overlay film, currently, the general method for increasing conduction is to cause structure multiple in corresponding position Riveted screw pole
It is miscellaneous, and production process is cumbersome, brings biggish cost pressure to enterprise.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of film covering method of television backboard, systems
Make simple process, can have electric conductivity in specific region, accuracy is high.
The technical solution adopted by the present invention to solve the technical problems are as follows:
A kind of film covering method of television backboard, comprising the following steps: Step 1: substrate is done using metal substrate, to base
Material is cleaned；Step 2: substrate side, by applicator roll glue coating with groove, substrate does not have in the region that groove covered
It applies glue；Step 3: pasting film in substrate side, the region and film that glue is coated on substrate are pasted, and are not coated with glue
Region can not paste film.
As an improvement of the above technical solution, further include step 4: cutting away and do not paste film on base material, make substrate
Partial denudation.
As an improvement of the above technical solution, the region contour of glue is not coated in rectangle.
As an improvement of the above technical solution, the groove is set to the outer peripheral surface of applicator roll.
As an improvement of the above technical solution, the length direction of the groove and the axial direction of applicator roll are parallel.
As an improvement of the above technical solution, further comprising the steps of between step 1 and step 2: paintingization masking liquid,
Then it dries, in the upper and lower surface formationization coating of substrate.
As an improvement of the above technical solution, further comprising the steps of: to carry on the back and paint in substrate other side roller coating, then dry.
As an improvement of the above technical solution, further comprising the steps of: protective film to be pasted on film, protective film covers base
Material is region-wide.
As an improvement of the above technical solution, the film is bright film or Matte film or PET film or aluminium foil.
The beneficial effects of the present invention are as follows:
Coating technique of the invention is simple and ingenious, chooses metal substrate and does substrate, is coated with by applicator roll with groove
Glue is arranged reasonable speed ratio parameter according to linear speed and coating roller diameter, so that substrate is not applied glue on specific region, essence
Certainly position, accuracy is high, and the region for being not coated with glue can not paste film, subsequent to be easy for cutting away this part film,
And then keep base material part exposed, to form specific conductive region in television backboard.
Specific embodiment
The present invention is further explained in the light of specific embodiments.
Embodiment 1: the present invention provides a kind of film covering methods of television backboard, comprising the following steps:
Step 1: doing substrate using metal substrate, substrate is cleaned；
Step 2: substrate side, by applicator roll glue coating with groove, substrate does not have in the region that groove covered
It applies glue；
Step 3: pasting film in substrate side, the region and film that glue is coated on substrate are pasted, and are not coated with the area of glue
Domain can not paste film.
The coating technique of the television backboard is simple and ingenious, and reasonable speed ratio is arranged according to linear speed and coating roller diameter and joins
Number, makes substrate not apply glue on specific region, precise positioning, and accuracy is high, and the region for being not coated with glue can not glue
Film is pasted, in the present embodiment, film can be packaged delivery after having pasted, and elder generation, which does not remove, does not paste film on base material, subsequent
Producer is easy for be punched this part film in punching press television backboard, and then keeps base material part exposed, thus
Specific conductive region is formed in television backboard.
Embodiment 2: the present invention also provides a kind of film covering methods of television backboard, comprising the following steps:
Step 1: doing substrate using steel plate, substrate is cleaned, then paintingization masking liquid is dried, in the upper following table of substrate
Face formationization coating；
Step 2: substrate side, by applicator roll glue coating with groove, substrate does not have in the region that groove covered
It applies glue；
Step 3: pasting film in substrate side, the region and film that glue is coated on substrate are pasted, and are not coated with the area of glue
Domain can not paste film；
Film on base material is not pasted Step 4: cutting away, and keeps base material part exposed；
It paints Step 5: being carried on the back in substrate other side roller coating, then dries；
Step 6: pasting protective film on film, it is region-wide that protective film covers substrate.
Wherein, metal substrate is steel plate, and film can be bright film or Matte film or PET film or aluminium foil, can arrive and play absolutely
The effect of edge and decoration, protective film and back paint can play protective action, after the cementing operation of step 3, can also be dried
It is dry, after the patch film operation of step 4, it can be cooled down；
In view of actual production, substrate can also shear slitting at multiple according to the actual size demand of television backboard
Television backboard is finally packaged.
Specifically, in step 2, the region contour of glue is not coated in rectangle, groove is set to the periphery of applicator roll
Face, the length direction of groove and the axial direction of applicator roll are parallel, and applicator roll often rotates a circle, and can form one piece of nothing in rectangle
Can the region of applicator roll glue coating be arranged according to actual needs in glue zone, corresponding if groove is arranged to other shapes
The region contour for being not coated with glue also there are other shapes.
The above, only better embodiment of the invention, but the present invention is not limited to above-described embodiments, as long as
The technical effect of the present invention is achieved by any identical or similar means for it, all should belong to protection scope of the present invention.
