2. Description of the Related Art Recently, when an electronic component is soldered and mounted on a printed circuit board, solder is printed on the printed circuit board by screen printing means, and the electronic component is mounted and temporarily adhered to heat before the solder dries. It is widely practiced to process and solder. Thus, these solder printing, electronic component mounting, solder heating, etc. are usually performed as each step of a continuous production line.

That is, when performing the above-mentioned screen printing, the solder corresponds to the printing ink, but a paste-like paste having a considerably higher viscosity than the ordinary printing ink is used and the soldering performance is improved. Thick film printing is required in order to increase the printing efficiency, and screen printing means is used for this purpose.For solder printing, stretchable woven screens such as nylon, tetron and silk are usually used for screen printing.

A metal screen, which is a woven fabric of steel fine wires, is also not stretchable, but its texture is unsuitable because it causes pinholes in the printing solder. Therefore, at present, etching is mainly performed on a thin metal plate. A metal screen in which fine holes are formed in a mesh shape is used.
However, since the metal screen is also made of a thin metal plate,
Naturally, unlike woven cloth screens such as nylon, it does not have elasticity.

Generally, in screen printing, after a squeegee presses ink through a screen printing plate toward the printing surface to print, the printed portion of the printing surface (the portion immediately after passing the squeegee) is immediately separated from the printing surface. This is the maximum requirement for clean printing, and in the case of stretchable screens such as nylon, there is a clearance from the initial printing surface so that the squeegee tip pushes ink through the screen printing plate during printing. When the screen is stretched, it comes into contact with the printing surface to perform printing, and at the same time when the squeegee passes (the printing of that portion is completed), the screen shrinks and restores immediately, and immediately leaves the printing surface, so that clean printing is possible. It is a thing.

However, since the metal screen has no elasticity, it cannot operate as described above. Therefore, recently, a combi-screen printing plate (see FIG. 3) is being used.
This is because the stretchable screen 2b of the conventional screen frame A'provided by stretching the stretchable screen 2 made of nylon or the like on the bottom surface of the rectangular frame 1'is used as a measure against bitterness for imparting stretchability to the metal screen. A metal screen 2a (provided by etching) is installed in the central portion, that is, a stretchable screen 2b is stretched with a set width between the periphery of the metal screen 2a and the rectangular frame 1. The metal screen printing plate does not have elasticity similar to that of the elastic screen printing plate.

However, the combination screen printing plate has the following problems. That is, since a stretchable screen portion with a set width (for example, 10 cm inside and outside) must be formed around the metal screen, it is necessary to increase the area of the entire screen frame or reduce the size of the metal screen. Since it requires a large installation space, it is difficult to install it on a line for manufacturing printed circuit boards, and the latter has a drawback that the size of the metal screen is limited.

Since the metal screen itself does not have the elasticity even if it has elasticity, the entire surface of the metal screen printing plate comes into close contact with the printing surface when pressed with a squeegee during printing, and the plate separation must be done at the same time. Not get
The finish of printing is poor, it is not suitable for precision pattern printing, and it is difficult to get clearance because thick film printing or repeated printing more than two times cannot be performed. There were a number of problems such as the need to clean the plate after each printing.

[Effect] A screen (particularly a metal screen) is stretched on the bottom of a screen frame in which front and rear frame trees are formed in a side arc shape, and a screen frame with an arc surface is provided, and a printing plate is formed on the arc surface screen. Since printing is performed by rotating the arc surface screen frame in a seesaw manner by a roller or the like in synchronization with the movement of the squeegee, the arc surface screen (printing plate) and the printing surface are aligned on a straight line. As soon as the squeegee tip comes into contact with the squeegee, the ink (solder) is extruded from the tip of the squeegee → The arc surface screen printing plate is separated from the printing surface immediately after the completion of the linear printing. In addition to being able to perform beautiful printing ideal for screen printing, it is also possible to use non-stretchable screen printing plates such as metal screens due to the above immediate plate separation action. There are very soo the features capable of performing as good as printing and over printing with conventional stretch screen printing plate.

Even when a non-stretchable screen such as a metal screen is used, a clearance can be set between the screen and the printing surface, and the plate separation is extremely good as described above. The above thick film printing can be performed, and this is particularly suitable for solder printing in which thick film printing is required.

Further, due to the features described in the preceding paragraph, it is possible to easily perform printing on a printed material having a slight unevenness on the surface, and it is possible to perform printing more than once on a printed material printed once. It is also possible to print another pattern for the second time on the open portion of the print pattern for the first time. Conventionally, it is completely impossible to perform the second solder printing on the open portion of the pattern of the printed circuit board on which the solder printing is performed, because the solder printing is a thick film, but in the present invention, this is also possible. It has become possible.

Since the arcuate screen screen frames are attached by the belts that are cross-bonded to each other, the guides of the arcuate surface rotate left and right in a seesaw fashion, but do not deviate from the set position.
Therefore, accurate printing without misalignment can be performed.

The seesaw type rotary movement of the arc surface screen frame is performed by parallel movement (with respect to the printing surface) of two rollers provided at intervals, and the tip of the squeegee is the center point of each of the two rollers. Since it is positioned at the apex of the isosceles triangle formed by the squeegee tip, the squeegee tip (one straight line) is located on the line of line contact between the arc surface screen frame and the printing surface that make line contact on one straight line. As a result, it is possible to always perform highly accurate printing without any error.

Unlike the conventional combi-screen frame, it is not necessary to form a composite structure of a stretchable screen and a non-stretchable screen, so that the manufacturing is easy and the cost can be remarkably reduced, and in the case of the arc-shaped screen frame of the present invention. Since the entire surface of the arc surface screen can be used as a printing plate, it is easy to increase the size of the screen printing plate, and in particular, it is possible to miniaturize it for solder printing. There is a great advantage that it can be easily installed and installed on the line.
