Description

Panel Sheet Cutting Machine {APPARATUS FOR CUTTING PANEL SHEET}

The present invention relates to a panel sheet cutting device, and more particularly to the optical panel sheet (PANEL SHEET) of the liquid crystal display (LCD) to be cut by a single operation into the overall shape including a fixing tip (TIP). It relates to a panel sheet cutting device.

The panel sheet cutting apparatus according to the prior art, as shown in Figure 1, has a shape that can be cut to match the outer shape of the plate body 21, the LCD panel sheet of the wooden board for supporting the entire panel sheet cutting apparatus The cutting blade 22 so as to cut to fit the outer shape of the cutting blade 22 of the line shape protruding on one surface of the plate-shaped body 21 and the fixing tips (11, 12) for fixing to the mold frame not shown ( It is extended to 22) and includes a tip cutting portion 23 in the form of a line protruding from the plate-shaped body 21 to cut the sheets to a predetermined value.

The blade 22 and the tip cutout 23 are embedded in the laser-cut groove 21a at a predetermined same depth as shown in a partial enlarged view of FIG. 1 to receive the support of only the plate-shaped body 21 and stand upright. Will be maintained.

In this case, in order to add support to the blade 22, the cutting groove of the plate-shaped body 21 must be deeply formed, and the blade 22 is gradually dug into the plate-shaped body 21 by repeatedly performing a plurality of cutting operations. There is a problem that the cutting of the sheet is made to be poor, and also the plate-shaped body 21 may be cut by the blade 22 to be dug.

In addition, the above-described conventional panel sheet cutting device is embedded in the longitudinal direction of the joint portion 24 or the blade 22 where the start and end portions of the blade 22 meet in the process of cutting a plurality of times through the vertical movement The warp phenomenon is remarkably generated in the long axis portion, the warp phenomenon has a problem that can produce a bad sheet by reducing the precision in cutting the sheet.

The problem to be solved is to solve the problems of the conventional panel sheet cutting device described above.

The present invention to solve the problem is made of a wooden board, a plate-shaped body having a cutting groove formed by forming a closed loop in the shape of the edge of the sheet to be cut and the laser cut in a concave-convex structure by a predetermined depth on the wooden board; A cutting blade having a concave-convex structure formed at a lower portion thereof so as to be inserted into a cutting groove of the concave-convex structure formed on the plate-shaped body, and a blade for cutting the sheet in direct contact with the sheet; And support means embedded in the periphery of the cutting blade so that the cutting blade inserted into the plate-shaped body maintains an upright state in the process of performing the cutting operation of the plate-shaped body several times through vertical movement. It is to provide a panel sheet cutting device.

Panel sheet cutting device according to the present invention by the above-described problem solving means is inserted into the support means between the joint portion or the long axis portion of the blade body is embedded in the longitudinal direction of the blade and the end portion of the blade embedded in the plate-shaped body By preventing the warpage of the blade to minimize the defects of the sheet being cut, there is an effect to improve the productivity.

In addition, since the lower end of the blade and the cutting groove of the plate-shaped body has an uneven structure, the blade is repeatedly embedded in the plate-shaped body deeply and thinly so that even if a plurality of cutting jobs are performed, the plate-shaped body is cut and broken by the blade. Since there is no work, there is an effect that can minimize the decrease in productivity due to work interruption.

Hereinafter, with reference to the accompanying drawings will be described in more detail with respect to the panel sheet cutting apparatus according to the present invention.

As shown in FIG. 2, the panel sheet cutting apparatus according to the present invention includes a plate-shaped body 21, a blade 22, a tip cutting portion 23, and a supporting means 25.

The plate-shaped body 21 is a wooden board, the cutting groove 21a is laser-cut so that the blade 22 can be inserted.

At this time, the cutting groove 21a is cut into a concave-convex structure having a lower level than the upper surface of the wooden board as shown in FIG. have.

The lower end portion of the blade 22 also forms an uneven structure so that the cutting groove 21a can be inserted into the uneven structure.

Therefore, the lower end of the blade 22 according to the present invention having a concave-convex structure is inserted into the convex portion of the cutting groove (21a), unlike the insert is inserted into the same depth in the conventional panel sheet cutting device, the convex portion cutting groove It is inserted into the recessed part of 21a.

On the other hand, the upper portion of the blade 22 in contact with the panel sheet to substantially cut the panel sheet forms the shape of an isosceles triangle with one angle of 42 ° and the other two angles of 69 °.

On the other hand, the tip cutting portion 23 is extended to the cutting blade 22 to protrude to the plate-shaped body 21 so that the panel sheet can be cut in accordance with the outer shape of the fixing tip for fixing to the mold frame not shown Formed.

The support means 25 supports the blade 22 so that flow does not occur in the cutting groove 21a as the blade 22 inserted into the plate-shaped body 21 repeatedly performs a plurality of cutting operations. As shown in Figure 3, the support means 25 has a cross-section 'c' shaped structure, the lower edge portion of the needle projection (25b) or blade (25c) to facilitate insertion into the plate-shaped body 21 Is formed, and a plurality of recesses 25a are formed at the upper edge portion of the support means 25.

The support means 25 having the above-described structure has a blade 22 inserted into the plate-shaped body 21 by inserting a closed loop, and the blades are inserted into the inside and the outside of the closed loop so as to be mutually supported. By condensing the density of the portion of the plate-shaped body 21 into which 22 is inserted, and further compressing the blade 22, the support force is maintained so that the upright state of the blade 22 can be maintained even after repeated cutting operations. to provide.

On the other hand, the support means 25 is the plate-shaped body by the pressing means 27 which is lowered from the upper side to the lower side after the protrusion 26a of the insertion aid means 26 is coupled to the recessed portion 25a formed on the upper edge portion. It is inserted into 21.

The insertion aid means 26 is the pressing means 27 and the blade 22 in the process of inserting the support means 25 into the plate-shaped body 21 by the pressing means 27 without the insertion aid means 26. ) To prevent damage to the blade 22.

In the above description, the supporting means 25 has a cross-sectional structure of the 'c' in the embodiment, but the present invention is not limited thereto, and a plate-shaped supporting means 25 may also be used as shown in FIG. 3.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawing.

1 is a view showing a conventional panel sheet cutting device.

2 is a view showing a panel sheet cutting apparatus according to the present invention.

3 is a view showing the insertion of the support means in the panel sheet cutting apparatus according to the present invention.
