DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing paste replenishing apparatus for use in a screen printing apparatus such as a cream coloring material or a solder paste.

[0002]

2. Description of the Related Art A printing paste replenishing apparatus of this kind, which comprises a cylindrical container having a discharge port at a lower end thereof, means for kneading the printing paste contained in the container, and kneading by the kneading means. And a means for extruding the printing paste from the discharge port are already known.

[0003]

In screen printing, a squeegee slides linearly in contact with the upper surface of the screen plate, and the sliding causes the printing paste to forcibly fill the pattern openings of the screen plate. The printed material is printed through the opening, and in order to achieve uniform printing quality or finished state and to improve printing accuracy, the viscosity of the printing paste at each printing is generally changed. Is required, the printing paste is a solder paste, when screen printing this on a printed circuit board, it is necessary to always be able to supply a solder paste having a certain viscosity suitable for printing, As the miniaturization of printed circuit boards is promoted,
Today, when high-density printing with a screen plate having pattern openings of minute dimensions has been required,
Of particular importance.

[0004] Among the solder pastes currently available as screen printing solder pastes for printed circuit boards, for example, a solder alloy powder having a composition of about 63% Sn and about 37% Pb with a bottom melting point and a high-viscosity liquid flux are kneaded to obtain a flux. Those having a content of about 9.3% are widely used. Such a commercially available solder paste is sold in a container made of a synthetic resin.

[0005] By the way, such a solder paste is a substance having a property of having no fluidity in a stationary state and having a fluidity when stirred or vibrated, that is, a substance having a chixotropy property. It is difficult to use it as it is taken out of the container for screen printing, and in use, it is necessary to impart viscosity suitable for printing by stirring and kneading. However, the paste in a container is required to be stored at 10 ° C. or less before use in order to prevent deterioration, but the paste stored at such a storage temperature is taken out of the container at the storage temperature. Even with stirring and kneading, it is almost impossible to increase the viscosity to a level suitable for printing in a short time. In addition, when the ambient temperature rises due to seasonal factors, factory location factors, factory facility factors, and the like, and the paste temperature reaches a temperature exceeding the appropriate temperature range, for example, a temperature of 26 ° C. or more. In addition, the viscosity of the paste exceeds the level suitable for printing, and becomes unsuitable for printing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to efficiently and quickly print a printing paste contained in a cylindrical container or a cartridge fitted in a hollow portion thereof. It is possible to apply a constant temperature and a constant viscosity that are optimal for printing and to send it out from the discharge port of the container. It is an object of the present invention to provide a supply device of a paste for use.
