Description
Technical Field
The utility model relates to a printing half tone technical field, in particular to edge thickening type printing half tone.
Background
The solar cell is a marked product which develops and utilizes new energy and is low-carbon and environment-friendly, the screen printing plays an important role in the manufacturing process of a positive electrode, a back electrode and a back electric field of the solar cell, and the screen printing process is the mainstream process mode of the screen printing process; the existing screen printing technology is to use photosensitive material to make screen printing plate by photoengraving method, the screen holes of the image-text part on the screen printing plate are through holes, but the screen holes of the non-image-text part are blocked. When printing, the ink or the slurry is transferred to the printing stock through the meshes of the image-text part by the extrusion of the scraper, and the image-text same as the original is formed. However, in the process of printing the battery piece, the phenomena of slurry leakage at the corner of the screen printing plate, explosion at the corner of the screen printing plate and over-quick drop of static tension exist, so that the service life of the screen printing plate is relatively short, the screen printing plate is frequently replaced on a battery piece production line due to over-short service life of the screen printing plate, and the production efficiency of the battery piece is directly influenced.
Therefore, in the utility model patent of patent number CN201810972790.8, the attached method of sticky tape of a screen printing half tone has been mentioned, also be at the attached sticky tape in non-printing area's edge, but after attached sticky tape, although the thickness at half tone edge has increased, but long-time the use, especially, the half tone is after wasing many times, the condition that the edge can appear deguming, still influenced the pleasing to the eye of structure, convenient to use nature and life, attached multiple sticky tape simultaneously, whether multiple sticky tape has the coincidence region, if then thickening part thickness is uneven, if not then adjacent region does not have the sticky tape effect and can't reach anticipated effect, consequently the utility model discloses an edge thickening type printing half tone has been developed to solve the problem that exists among the prior art, through the retrieval, not discover with the utility model discloses the same or similar technical scheme.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is: the utility model provides an edge thickening type printing half tone to solve the problem that the sticky tape edge can't rationally paste among the prior art.
The technical scheme of the utility model is that: the utility model provides an edge thickening type printing half tone, includes the frame and opens the gauze of establishing in the frame, the gauze middle part has a printing region, and the part that the skew printing is regional is the non-printing region, be provided with the printing pattern in the printing region, the gauze is including scraping knife face and printing face, it has four thickening sticky tapes, four to adhere to in the non-printing region of printing face thickening sticky tape all is isosceles trapezoid to be in the direction all around in the printing region outside respectively, both sides limit is parallel with the frame diagonal respectively, has a dead slot between the adjacent thickening sticky tape side, the laminating has silver dragon sticky tape in the dead slot, silver dragon sticky tape sets up along the frame diagonal.
Preferably, the distance between the end part of the inner side of the thickened adhesive tape and the end part of the printing area is 0.3-0.5 mm.
Preferably, the inner side end of the silver dragon adhesive tape extends to the top corners of the printing area and covers the area which is in a right triangle shape at the four top corners of the printing area.
Preferably, the area of the printing pattern occupies 1/4-1/3 of the area of the printing area.
Preferably, the outer side end of the thickened adhesive tape extends to the outer side of the frame and is folded and adhered to the side wall of the frame; the outer side end of the silver dragon adhesive tape also extends to the outer side of the frame, a cutting groove is formed in the middle of one end protruding out of the frame, and the silver dragon adhesive tapes at the two ends of the cutting groove are folded and adhered to the side wall of the frame.
Compared with the prior art, the utility model has the advantages that:
(1) the utility model thickens the non-printing area of the traditional printing screen, the wear resistance of the printing screen is 1 ten thousand higher than that of the non-thickened screen after the edge is thickened, the service life of the printing screen is prolonged, and the production cost of a manufacturer is reduced;
(2) the middle of the thickened adhesive tape is not overlapped and adhered, a silver dragon adhesive tape is arranged between the thickened adhesive tape and the thickened adhesive tape, the silver dragon adhesive tape is solvent-resistant and water-resistant, the surface of the silver dragon adhesive tape is not corroded by a solvent, and the back adhesive is solvent-resistant, is not easy to fall off, is attractive and elegant, and is a preferred adhesive tape for edge sealing of a net frame;
(3) the inner side end of the silver dragon adhesive tape extends to the top corners of the printing area and covers the area of the printing area, of which the four top corners are right-angled triangles, so that the situation that the four top corners of the printing area are easy to deform is prevented, and a certain reinforcing effect is achieved;
(4) the outer side ends of the thickened adhesive tape and the silver dragon adhesive tape extend to the outer side of the frame and are adhered to the side wall of the frame, so that the side edges of the gauze can be effectively prevented from degumming, and a reinforcing effect is further achieved;
(5) because the silver dragon adhesive tape extends to the top corner of the printing area, the silver dragon adhesive tape has certain thickness, the scraper can press down the gauze in the printing process, the thickness difference can enable the gauze to have certain deformation, the width of the scraper is slightly larger than the width of a printing pattern under normal conditions, if the distance between the edge of the printing pattern and the inner side end of the silver dragon adhesive tape is too small, the end of the scraper is directly pressed on the gauze, the gauze can deform in a short distance, and the precision is poor when the pattern is printed due to long-time tension failure, therefore, the area of the printing pattern accounts for 1/4-1/3 of the area of the printing area, the distance between the edge of the printing pattern and the inner side end of the silver dragon adhesive tape is increased, at the moment, the gauze deformation is allowed to occur in a longer buffer distance, the gauze tension is not.
