Description

Stereo printing device {Printing method metal mask}

The present invention relates to a three-dimensional printing device, and more particularly, the magnetic force is transmitted by opening and closing the door after fixing the magnet in the printing table, or on the contrary, it is completely blocked to close and tightly close the printing table and the printing disc. According to this, the magnetic force is completely released after the printing is finished, so that the height of the printed layer can be more firmly and stably supported to improve the strength, and the three-dimensional printing can be more efficiently expressed, that is, the three-dimensional surface can be effectively expressed. It is about a printing device.

Screen printing refers to a printing method that transfers ink to paper by passing ink through a mesh hole using a plate composed of wires on a surface where a mesh is attached to a wooden frame.

In the past, silk screen printing was called silk screen printing. Recently, it is called screen printing because it uses nylon, tetron, and stainless steel mesh. In screen printing, flat printing is a screen frame with a mesh on a paper. Place the ink on the screen frame and push the ink into the screen hole with a rubber spatula to print on paper.

Screen printing is an ultra-precision printing technology that prints on the surface of quartz glass (Sio2), which is different from general offset printing or letterpress printing, and is a printing technology field used for manufacturing thin-film display windows or ultra-thin TV screens. In the case of screen printing, the metal mask method, that is, the pattern or text to be printed, is first corroded to a fine mesh stainless steel screen panel (PDP; Plasma Display Pancl), which is used as a printing original. Printed with hot color ink on the surface of quartz glass with excellent surface smoothness, the printing layer is about 0.2mm thick.

At this time, the printing disc is placed on the upper side of the to-be-printed quartz glass (hereinafter referred to as the to-be-printed object), and a plurality of inlets are installed on the lower surface of the to-be-printed material by inhaling and fixing the back surface of the to-be-printed object at regular intervals The cylinder rod moves up and down the printing table with a plurality of permanent magnets to suck and fix the printing disk made of stainless steel screen mesh.

Conventional printing machines are mechanically vibrated when the printing table descends a certain distance by the inlet of the cylinder rod and then rises for printing, so the thickness of the printed layer is very fine (0.2 mm) due to this vibration. Spreading phenomena and uneven edges of the printed layer have resulted in a high product defect rate in the high-precision printing, which requires extremely precise printing, resulting in deterioration of product reliability.

On the other hand, a three-dimensional printing (or after-printing) is a kind of planar printing for a three-dimensional printing.

In general, the layer height of the three-dimensional printing is less than 0.2mm at one time printing, so to print five times to print the thickness of the printed layer to about 1mm.

The printed matter completed as described above is transferred to a substrate and transferred to a high temperature of about 1.800 ℃ to undergo a baking process.

In such three-dimensional printing, important factors influencing the quality of printing are the tightness of the space between the printing table and the printing disc and the strength of the printing layer.

In order to close the space between the printing table and the printing disc, a magnetic table method in which a magnet device is installed on a printing table or a table suction method in which a suction device is installed on a table is used.

However, in the conventional magnet table or air suction method, even a close contact between the to-be-printed object and the printed disc is left.

In addition, if the height of the printed layer is raised to 1 to 2mm, the circular shape is damaged during the firing process, so that the three-dimensional feeling is not only dropped, and since there is no rigidity, the corner part of the printed layer is separated or crushed, so it is difficult to express the three-dimensional feeling.

In this way, the conventional printing press has a small strength of the printing layer during the last step of firing, so that the angular form of the printing layer is lost or ink bleeding occurs, so that the space between the printing table and the printing disc is closely and precisely adhered. In addition, three-dimensional printing with high strength of the printing layer was required while increasing the height of the printing layer.

In the conventional three-dimensional printing as described above, the vibration is generated and the printed layer is raised in the process of operating up and down using an air cast to close the printing plate and the printing disc to operate the magnetic plate up and down by embedding a magnet in the printing table. There was a lot of difficulty in stacking and the defective rate of the product has a serious problem.

Therefore, the object of the present invention is to solve the problems as described above, the three-dimensional printing device is fixed to the magnet in the printing table after the magnetic force is transmitted by opening and closing the door or on the contrary to completely block the print table and As the magnetic disc is completely released after the printing is completed, it is possible to maintain the height of the printing layer more firmly and stably, thereby improving the strength and making the three-dimensional printing more efficient. It is to provide a three-dimensional printing device that can effectively express the degree of protrusion.
