Description

Masking frame manufacturing apparatus {Making mask-frame device}

The present invention relates to a mask frame manufacturing apparatus, and more particularly to a method and apparatus for manufacturing a mask frame that can improve the productivity in the manufacturing process by reducing the time required to manufacture the mask frame and minimizes the use of materials.

In general, the mask frame supports the shadow mask so that the shadow mask is positioned at an appropriate position with respect to the panel, and at the same time serves to correct a certain amount of doming of the shadow mask.

That is, when the shadow mask causes the domming due to the heat energy increase due to the electron beam collision, the shadow mask absorbs the heat and performs the first correction, and then transfers the heat of the mask frame to the spring member to perform the second correction, thereby correcting the shadow mask's domming. do.

At this time, the shadow mask is dominant in a direction in which the horizontal width is wider than the vertical width, so that the positions of the beam passing holes are mainly shifted in the horizontal direction. The fluorescent film screen which receives the electron beam and emits light emits three color phosphors vertically. Since they are arranged parallel to each other, the positional movement of the holes for beam passing mainly changes the landing trajectory of the electron beam in the horizontal direction, causing landing errors or other colors to emit light.

Looking at the manufacturing process of the mask frame, the manufacturing process of the mask frame, cutting a plate of a suitable size to form each mask frame from a metal base material, and using a deep drawing process to form a mask frame After shaping, cutting the portion to which the shadow mask is coupled and the hole forming portion for fastening the other parts are included.

At this time, the part cut to join the shadow mask occupies a relatively large area in the use of the entire material, and if it cannot be used for the mask frame smaller than the size of the cut part, it must be discarded, causing a large material loss. As a result of integrally molding the mask frame, a problem of enlarging the volume of the apparatus used for manufacturing the mask frame has arisen.

Therefore, an object of the present invention is proposed to solve the above-mentioned problems, manufacturing a mask frame that can improve the productivity in the manufacturing process by preventing the waste of materials used for manufacturing the mask frame, minimizing the time required To provide a method and apparatus.
