Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a metal mask printing plate using a metal mask used for printing with high dimensional accuracy.
[0002]
[Prior art]
Since conventional metal mask printing plates do not have elasticity, the metal mask with the printing pattern formed at the center of the ridge is bonded with an adhesive using a screen printing plate body with a ridge attached to the printing plate frame. After fixing by adhesion, the wrinkles in the metal mask portion are removed, and a photosensitive emulsion is coated on the wrinkles on the outer peripheral portion of the metal mask, exposed, and filled with wrinkles.
[0003]
[Problems to be solved by the invention]
The conventional metal mask printing plate has the disadvantages that the work of attaching the metal mask to the printing plate frame is difficult, time-consuming and expensive, and the metal mask printing plate is attached with the metal mask attached to the printing plate frame. The manufacturer had to transport from the manufacturer to the printing manufacturer, and there were drawbacks in that the transportation work was troublesome and the transportation cost was high.
[0004]
In view of the conventional drawbacks as described above, the present invention can be easily attached and removed in a short time in a state in which the metal mask is attached to and detached from the printing plate frame, and an elastic force is applied to the metal mask. It is an object of the present invention to provide a printing mask manufacturer with a metal mask printing plate that can transport only a metal mask, can be manufactured, attached, removed and transported easily and can be carried out at low cost.
[0005]
The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a printing pattern having a printing plate frame formed in a square frame shape, and an attachment piece formed by bending an outer periphery that is detachably attached to the printing plate frame at a substantially right angle. A formed metal mask, a long groove-like sandwiching piece insertion groove into which a sandwiching piece into which a mounting piece of the metal mask formed on each frame side of the printing plate frame is inserted and fixed, and the printing plate An oblong locking device insertion groove formed in an inner portion so as to communicate with the sandwiching piece insertion groove formed on one vertical frame side and horizontal frame side of the frame, and an inner wall surface of the locking device insertion groove A slide member having a chevron-shaped or saw-toothed engagement piece on the outer surface thereof slidably mounted on the outer surface, and a chevron-shaped or saw-toothed engagement that meshes with the engagement piece of the slide member, respectively. A slide fixing member that slides outward in the locking device insertion groove in which a metal piece is formed and an outer surface presses the clamping piece outward to fix the metal mask mounting piece; and the slide member The metal mask printing plate is composed of at least one locking device that slides and fixes each of these to a predetermined position.
