Description

[Detailed description of the invention] a. Purpose of the invention (industrial field of application) The cutter holder of the panel cutting device according to this invention cuts a large panel such as glass and cuts a liquid crystal panel or a liquid crystal panel of a predetermined size. A device that is incorporated into the panel cutting device used when making glass slides for specimens so that the panels can be cut efficiently and with a high yield, especially without applying excessive force to the panels. It is.

(Prior art) When manufacturing liquid crystal panels used in the displays of various electronic devices or slide glasses used for preparing microscopic specimens, large panels are cut to produce liquid crystal panels of a predetermined size. I'm trying to get a glass slide.

The process of cutting a large panel into small boards of a predetermined size is done automatically using a cutter that moves along the top of the panel placed on a table with a flat top. ing.

That is, as shown in FIG. 4, the head 4, which supports the cutter 3 on the bottom surface, is continuously moved in the left-right direction in FIG. Using a cutting device that is capable of intermittent movement of a fixed length in the front and back directions of the panel 1, the head 4 is moved in the left and right direction in FIG. 4 while pressing the cutter 3 against the top surface of the panel 1. A cut is formed as shown by the chain line a in FIG. Once one horizontal cut in Figure 5, indicated by the chain line a, is formed, move the head 4 a certain length in the front and back directions in Figure 4, and then move the head 4 again in the left and right directions in the Figure. By repeating the process, a large number of parallel cuts are formed on the panel 1 at equal intervals, as shown by chain lines a and a in FIG.

After forming the horizontal cuts shown by chain lines a and a in FIG. 5, the table 2 is then rotated 90 degrees around the vertical axis, and the head 4 is again moved in the left-right direction in FIG. Vertical cuts are formed in the panel 1 as shown by broken lines b and b in FIG.

Through this work, the large panel 1 can be
It is divided into small rectangular plates surrounded by a and broken lines b and b.

(Problems to be Solved by the Invention) However, in the panel cutting device constructed and operated as described above, conventional problems have occurred as described below.

That is, the head 4 with the cutter 3 provided on the lower surface is
When cutting the panel 1 such as glass while moving it horizontally in the left and right direction in the figure, the cutter 3
For example, when the head 4 moves to the right in Figure 4, it contacts the top surface of the panel 1, and when it moves to the left in the figure, the head 4 rises a little and the cutter 3 and panel 1 are separated. I have to.

Therefore, the time required for cutting the panel 1, such as glass, increases by the amount of time required for the head 4 to return to its original position.

If the cutter 3 and panel 1 are configured so that they come into contact with each other when the head 4 moves not only to the right but also to the left in FIG. 4, the efficiency of the cutting operation can be improved. However, in conventional cutting devices, the cutter 3 is fixed to the bottom surface of the head 4, so if the installation angle of the cutter 3 is even slightly incorrect, the cutting line of the cutter 3 and the head 4 Due to the discrepancy with the direction of movement of the cutter, excessive force is applied to the panel when cutting it, resulting in damage to the panel, making it difficult to use reciprocating machining, which requires strict cutter installation accuracy. .

The cutter holder of the panel cutting device of the present invention is intended to eliminate the above-mentioned inconveniences.

b. Structure of the invention (means for solving problems) The cutter holding part of the panel cutting device of the invention is the tip of a rotary support piece that is rotatable around a first vertical axis provided on the upper surface of the base end. A katsuta is supported on the underside.

The lower end of a hanging rod is loosely inserted into the inside of a circular hole formed on the upper surface of the rotation support piece at a position offset from the first vertical shaft. This hanging rod hangs down from the underside of the tip of a rotating top fixed to a second vertical shaft which is coaxial with the first vertical shaft and can be rotated 180 degrees at a time by a motor.

(Function) When cutting a large panel using the panel cutting device incorporating the cutter holder of the present invention constructed as described above, the panel is placed on the top surface of the table, and the panel is placed on the head above the panel. While pressing the supported cutter against the upper surface of the panel, the head is reciprocated in a linear direction to form parallel cuts in the panel at equal intervals.

When the head moves back and forth, the cutter comes into contact with the top surface of the panel and cuts the panel, no matter which direction the head moves. By energizing the motor each time the direction of movement of the cutter changes, the rotary support piece is rotated 180 degrees, so that the first vertical shaft that rotatably supports the rotary support piece is always located in front of the cutter. .

When the motor is energized, the rotating support piece moves approximately 180 degrees.
The lower end of the hanging rod is rotated 180 degrees by the motor, and the first vertical shaft that rotatably supports this rotary support piece is positioned in front of the cutter in the direction of movement. Since the rotary support piece is loosely engaged with the circular hole drilled in the upper surface of the rotary support piece, even after the hanging rod has rotated 180 degrees, the rotary support piece will
It becomes slightly rotatable around the first vertical axis.

For this reason, based on the installation error of the cutter,
Even if the direction of movement of the head and the direction of the cutting line of the cutter are slightly misaligned, the rotating support piece to which the cutter is attached will rotate slightly around the first vertical axis, and the direction of movement of the head and the direction of the cutting line will be slightly different. Match the direction of the cut line to prevent excessive force from being applied to the panel in contact with this cutter.

(Example) Next, the present invention will be explained in more detail by explaining the illustrated embodiment.

1 to 3 show an embodiment of the cutter holding part of the panel cutting device of the present invention, FIG. 1 is a view seen from the front in the direction of movement of the head, and FIG. 2 is a view taken from A--A in FIG.
A sectional view, and FIG. 3 are BB sectional views of FIG. 2.

A bearing member 7 is attached to a head 4 fixed to a slider 6 that is movable along a horizontally arranged guide rail 5, and the bearing member 7 is attached to the head 4 so that its vertical position relative to the head 4 can be freely adjusted (the adjustment mechanism is a conventionally known one). (Due to this, illustrations and explanations are omitted.) are installed,
A first vertical shaft 8 is suspended from the lower surface of the bearing member 7. This first vertical shaft 8 has a rotation support piece 9
The proximal end of is pivotally supported.

An abacus bead-shaped cutter 3 is supported on the lower surface of the tip of the rotary support piece 9 so as to be rotatable about a horizontal axis.

Further, a circular hole 10 is bored in the upper surface of the rotary support piece 9 at a position away from the first vertical shaft 8, and the lower end of the hanging rod 11 is inserted into the third hole inside the circular hole 10.
Insert it loosely as shown in the figure.

This hanging rod 11 is suspended from the lower surface of the tip of a rotary piece 14 which is rotatable by a motor 13 by 180 degrees. The drive shaft 12 (second vertical shaft) of the motor 13 fixed to the base end of the hanging rod 11 is concentric with the first vertical shaft 8, and when the motor 13 is energized, the hanging rod 11 is rotated 180 degrees. It can be rotated freely.

The cutter holder of the present invention is constructed as described above, but when cutting a large panel with a panel cutting device incorporating this cutter holder,
In the same way as cutting with a conventional cutting device, a panel is placed on the top of a table, and the cutter 3 supported by the head 4 above the panel is pressed against the top of the panel while the head 4 is cut in a straight line. This panel is moved back and forth in the direction to form mutually parallel cuts at equal intervals.

During this reciprocation of the head, the cutter 3 comes into contact with the top surface of the panel and cuts the panel no matter which direction the head 4 moves, but the direction of the cutter 3 correctly matches the direction of movement of the head 4. Similarly, each time the moving direction of the head 4 changes, the positions of the cutter 3 and the first vertical shaft 8 are exchanged. That is, the direction of movement of the head 4 is adjusted so that the first vertical shaft 8, which rotatably supports the rotary support piece 9, is always located in front of the cutter 3 in the direction of movement of the head 4 (on the right side in FIGS. 2 and 3). By energizing the motor 13 each time the rotational support piece 9 changes, the rotary support piece 9 is rotated 180 degrees. The rotation angle of the rotation support piece 9 is regulated by the plate piece 1 fixed to the rotation piece 14.
6 and two photo sensors 15, 15 arranged around the rotary piece 14 with a phase difference of 180 degrees.

By energizing the motor 13, the rotary support piece 9 rotates approximately 180 degrees, and the first vertical shaft 8, which rotatably supports the rotary support piece 9, is positioned in front of the cutter 3 in the direction of movement. It will be like that. However, even in this state, the lower end of the hanging rod 11, which is rotated 180 degrees by the motor 13, is loosely engaged with the circular hole 10 bored in the upper surface of the rotary support piece 9. The rotational support piece 9 is slightly rotatable about the first vertical shaft 8 within the range in which the lower end of the hanging rod 11 can move inside the circular hole 10.

Therefore, even if the moving direction of the head 4 and the direction of the cutting line of the cutter 3 are slightly deviated due to an installation error of the cutter 3, the rotating support piece 9 to which the cutter 3 is attached will be in the first position. It rotates slightly around the vertical axis 8 of the cutter 3 to match the advancing direction of the head 4 with the direction of the cutting line of the cutter 3, and acts so that no unreasonable force is applied to the panel with which the cutter 3 comes into contact.

c. Effects of the invention Since the cutter holder of the panel cutting device of the present invention is configured and operates as described above, it is possible to cut panels such as glass, even when the head to which the cutter is attached moves in any direction. This makes it possible to efficiently perform the above-mentioned panel cutting work, and also ensures that the direction of movement of the head matches the direction of the cutting line of the cutter during cutting work, without applying excessive force to the panel. , it is possible to perform cutting work with a high yield.
