Description

Drying equipment for printing film on screen printer

Technical Field

The utility model relates to a silk screen printing machine stoving technical field especially relates to a drying equipment of last printing film of silk screen printing machine.

Background

The silk screen printing machine, also known as silk screen printing machine, is the machine that uses the screen printing plate as the printing template and applies the seal, belongs to one kind of printing machine, and the silk screen printing machine is the machine of printing characters and image, is the collective name of the machine or equipment that is used for producing the printed matter, and the silk screen printing machine belongs to the more representative printing equipment among the porous plate printing machine, and the material of making the silk screen can also use nylon wire, copper wire, steel wire or stainless steel wire etc. besides true silk. And can be classified into a flat screen printer, a curved screen printer, a rotary screen printer, and the like.

The silk-screen printing is to laminate the protective layer and the interlayer on the cast diaphragm according to the design requirement of the work order, print the inner electrode slurry on the ceramic medium, and laminate the inner electrode slurry together according to a certain dislocation mode to form a whole, namely a bar block.

The inner electrode of the capacitor is used for storing charges, so the flatness, continuity, structure and the like of the inner electrode pattern directly affect the electrical performance and reliability. Therefore, silk-screen printing has very high requirements on process sanitation, precision of production equipment, operating skills of staff and quality awareness. In the aspect of process sanitation, as silk-screen printing is to directly operate the core inner electrode of the capacitor, the requirements on personal sanitation of field operators, large production environment and cleanliness of raw materials are strict, and no dust or impurities exist. Meanwhile, the silk screen printing is to print the inner electrodes and to overlap the media with the inner electrodes, so that the requirement on the precision of the equipment is high, the opposite positions of the upper and lower electrodes cannot be shifted or deflected during printing, and otherwise, the reliability of the capacitor is directly influenced.

The screen printed inner electrodes have a crucial influence on the performance of the chip. The silver weight and the smoothness and flatness of the silver layer are important parameters for measuring the quality of the inner electrode. The uneven thickness and printing of the silver layer can increase the production cost, and when the chip is under the action of an electric field, the concave and convex parts of the internal electrodes can suddenly collect excessive charges to cause the breakdown of the internal electrodes, or the plate resistance is formed to cause the excessive heating of the internal electrodes to cause the burning-out of the internal electrodes. Conversely, if the silver is too heavy or the electrodes are not printed well, the capacitance of the capacitor is directly affected and its loss increases.

Can pass through the change of template, the different printing style of change that can be convenient, thereby reach the effect of convenient printing, and when scraping the head and scraping the china ink and glue, the film is both ends tightened, so just enable the film and spread, and can also bulldoze the film by the push template downwards when scraping the china ink and glue, lead to film tension very easily to change, cause the film to hang and can't spread after the seal, lead to printing crooked, and when current silk screen printing machine frictioning, it is even to accomplish strength hardly, the silk screen printing machine belongs to high-accuracy lithography apparatus, as long as tension is slightly, the printing will take place the error, consequently, lead to present silk screen printing machine the deviation very easily to appear when the printing, and the film printing belt printing of printing stoving has been accomplished the back and has been convoluteed the lapping again, deviation department is difficult to change again and is proofreadied.

The screen printer is also used for printing electronic elements, conductive silk threads can be printed on a strip-shaped film to form conductive circuits, so that the printing of the electronic elements is finished, the efficiency of the screen printer is far higher than that of the mechanical arm, when the screen printer is used for printing, two scraping heads are used for scraping conductive ink paste back and forth, the conductive ink paste is scraped and printed on the strip-shaped film according to the shape of a template, the electronic elements are printed, different printing patterns can be conveniently changed through the replacement of the template, so that the effect of facilitating the printing is achieved, when the scraping heads scrape the ink paste, two ends of the strip-shaped film are tightened, so that the strip-shaped film can be spread, the film is a strip-shaped film roll, one end of the film is folded, the strip-shaped film is tightened to enable the screen printing to be smoother, the aim of clear printing is achieved, and the film is strip-shaped after being unfolded and wound into a roll shape, need dry the china ink glue of printing after the printing is accomplished, ensure that the printing is stable, current stoving all relies on high temperature to dry, but the film is very thin, only less than 1mm thickness, and high temperature deformation very easily leads to the printing to warp unable the use.

Based on this, the utility model discloses a drying equipment of last printing film of silk screen printing machine to solve above-mentioned problem.
