Description

Description: TECHNICAL FIELD The present invention relates to a cutting machine for cutting a plate-like material such as a glass plate along concentric circular inner and outer cutting lines.

<Prior Art and its Problems> As is well known, a so-called optical or magnetic disk having an annular plate shape has been widely put into practical use as an optical or magnetic storage medium. Conventionally, the optical or magnetic disk substrate has been formed of an appropriate metal material such as aluminum. However, for various reasons such as improvement in surface accuracy, the optical or magnetic disk substrate is recently replaced with glass. Forming has been proposed and has come into practical use.

Thus, in order to form the substrate from glass, generally, a rectangular or rectangular glass plate is cut along concentric circular inner and outer cutting lines, thus leaving between the circular inner and outer cutting lines. It is necessary to obtain an annular plate that does.

However, due to the fact that glass plates are highly brittle and are significantly more difficult to cut than metal plates, a cutting machine suitable for automatically cutting glass plates along the circular inner and outer cutting lines described above. Has not been proposed yet. Under the present circumstances, a glass plate is cut by a skilled worker's manual work along the circular inner and outer cutting lines to obtain an annular plate. Therefore, the production efficiency is remarkably low and the production cost is remarkably high. Further, it is not possible to stably obtain a highly accurate annular glass plate (that is, an optical or magnetic disk substrate).

<Problem of the invention> Therefore, a main technical problem of the present invention is to provide a plate-shaped material having high brittleness and difficult-to-cut property such as a glass plate.

<Preferred Specific Examples of the Invention> Specific examples of the cutting machine configured according to the present invention will be described in detail below.

Referring to FIG. 1, the illustrated cutting machine comprises a disk mounted rotatably about a central axis extending substantially vertically (extending substantially perpendicular to the plane of the drawing in FIG. 1). It includes a support base 2. Four material holding chuck means 4 are arranged on the support base 2 at an angular interval of 90 degrees. The support base 2 is drivingly connected to the intermittent movement means 6 which may be an electric motor through an appropriate transmission mechanism (not shown). The intermittent movement means 6 causes the support base 2 to intermittently rotate in the direction indicated by the arrow 8 every 90 degrees. 90 on the support base 2
A material loading area 10, a cutting work area 12, a material unloading area 14 and a chuck cleaning area 16 are defined in order at angular intervals of degrees when viewed in the direction of rotation of the support base 2 indicated by the arrow 8. First
As can be easily understood by referring to the drawings, the support base 2 is rotated by 90 degrees at intervals by the moving means 6, so that each of the chuck means 4 has a material loading area 10 and a cutting operation. The area 12, the material unloading area 14, and the chuck cleaning area 16 are sequentially positioned.

A material carrying-in means generally indicated by numeral 18 is provided in relation to the material carrying-in area 10, and a cutting blade device generally indicated by numeral 20 is provided in relation to the cutting work area 12.
Material unloading means generally designated 22 is provided in association with the material unloading area 14, and a cleaning device generally designated 24 is associated with the chuck cleaning area 16.

The chuck means 4 will be described with reference to FIGS. 2 to 4. In the illustrated specific example, the chuck means 4 is described.
Each of them has a chuck plate 26 and a holding plate 28.
The chuck plate 26 and the holding plate 28 may have any suitable shape such as a circular shape or a rectangular shape, but when the material to be cut is a square shape, it is convenient to have a substantially square shape corresponding thereto. As clearly shown in FIGS. 2 and 3, four concentric annular grooves 30, 32, 34 and 36 are formed on the upper surface of the chuck plate 26. The chuck plate 26 includes the outer edge region 38, four substantially annular region portions 40, 42, 44 and 46 in which the annular grooves 30, 32, 34 and 36 are formed, the peripheral region 47 and the inner peripheral region thereof. Region 48, which extends parallel to 47, is non-breathable, but the other portions shown in FIG. 3 with cross hatching are breathable. In order to achieve such air permeability, a large number of vertical through holes 49 (FIG. 2) may be formed in the chuck plate 26 in the portion shown by cross hatching in FIG. Alternatively, only the portion of the chuck plate 26 indicated by the cross hatched lines in FIG. 3 may be formed of the porous material. As can be understood by referring to FIGS. 2 and 4, an inner recess 50 and an outer recess 52 are formed on the upper surface of the holding plate 28. The inner recess 50 has a substantially rectangular shape, and eight arc-shaped support lands 54 are left in the inner recess 50. The outer recess 52 extends continuously along the peripheral edge of the inner recess 50, and a separating land 56 that extends continuously exists between the inner recess 50 and the outer recess 52. An outer peripheral land 58 that extends continuously exists on the outer side of the outer recess 52. As is apparent from FIG. 2, the upper surfaces of the support land 54, the isolation land 56 and the outer peripheral land 58 are on the same plane. The outer peripheral land 58 is located corresponding to the peripheral region 47 of the chuck plate 26, and the isolation land 56 is the chuck plate.
Located corresponding to region 48 at 26. A circular recess 60 is formed in the center of the lower surface of the holding plate 28. Furthermore,
The holding plate 28 is provided with a first communication passage that allows the inner recess 50 and the recess 60 to communicate with each other, and a second communication passage that allows the outer recess 52 and the recess 60 to communicate with each other. .
The first communication path is formed by a hole 62 extending from an upper end opened to the inner recess 50 to a lower end opened to the recess 60. On the other hand, the second communication passage includes a hole 64 extending downward from the upper end opened in the outer recess 52, a hole 66 extending substantially horizontally, and an inner end of the hole 66 to a lower end opening downward in the recess 60. Includes an extending hole 68. The holding plate 28 has
Furthermore, one side surface (left side surface in FIGS. 2 and 4)
A large diameter hole 70 is formed to extend inwardly from. Above hole 64
The lower end of is connected to the large diameter hole 70, and the outer end of the hole 66 is also connected to the large diameter hole 70. An opening / closing control member 72 is rotatably attached to the large diameter hole 70. The opening / closing control member 72 has a head portion 74, a small diameter portion 76, and a valve portion 78 having an outer diameter corresponding to the inner diameter of the large diameter hole 70. The opening / closing control member 72 has a fastening plate 82 having a fastening plate 80 formed with an elongated slot for receiving the small diameter portion 76.
By fixing to one side surface of the holding plate 28 by (FIG. 3), it is rotatably mounted at a predetermined position. The valve portion 78 of the opening / closing control member 72 is formed with a hole 84 extending in the diameter direction and a hole 86 extending from the hole 84 to the tip. When the opening / closing control member 72 is in the angular position shown in FIG. 2,
The holes 84 and 86 connect the holes 64 and 66 to each other, and thus the outer recess 52 and the recess 60 to each other. On the other hand, when the opening / closing control member 72 is rotated about 90 degrees by gripping the head 74, the hole 84
And the hole 64 are not in communication with each other, and thus the outer recess 52 and the recess 60 are not in communication with each other.

As shown in FIGS. 2 and 4, through holes 88 are formed in the holding plate 28 at appropriate intervals in the outer recess 52, and through the through holes 88, the fastening bolts 89 are fixed to the support base. The holding plate 28 is fixed at a predetermined position on the support base 2 by being screwed onto the base 2. The chuck plate 26 is
It is attached to the holding plate 28 by a plurality of connecting members 90. Second
As shown in the drawing, a groove 92 is formed on the side surface of the chuck plate 26, and a shoulder portion 94 is formed on the side surface of the holding plate 28. The connecting tool 90 is fixed to the side surface of the holding plate 28 by fastening bolts 100 by locking its upper locking leg 96 in the groove 92 and its lower locking leg 98 in the shoulder portion 94.

In the chuck means 4 as described above, the recess 60 formed on the lower surface of the holding plate 28 is provided with the control valve 102 and the control valve 102 via an appropriate communication passage including the communication passage 101 formed in the support base 2. Control of 104, vacuum source 106 and water source 1
It is possible to selectively communicate with 08. More specifically, when the material to be cut is placed on the chuck plate 26 in the material carrying-in area 10 (FIG. 1), the recess 60 is brought into communication with the vacuum source 106. A plate-like material such as a glass plate placed on the chuck plate 26 is a relatively large square as shown by a two-dot chain line GL in FIGS. 2 and 3, and its outer edge is on the outer peripheral region 47. When it is located, the opening / closing control member 72 is in the second position.
It is located in the open position shown in the figure. Therefore, the recess 60 is communicated with the inner recess 50 by the hole 62, and the recess 60 is communicated with the outer recess 52 through the holes 68, 66, 86, 84 and 64. Thus, air is sucked through all the breathable parts of the chuck plate 26 and the material GL is adsorbed on the chuck plate 26. On the other hand, when the material placed on the chuck plate 26 is a relatively small square as shown by the chain double-dashed line GS in FIGS. 2 and 3, and its outer edge is located on the area 48, The opening / closing control member 72 is rotated about 90 degrees from the open position shown in FIG. 2 to the closed position. Therefore, the recess 60 is communicated with the inner recess 50 by the hole 62, but the recess 60 and the outer recess 52 are not communicated with each other. Thus, only in the area inside the isolation land 56, the chuck plate 26
Air is sucked through the breathable parts of the material and the material GS is placed on the chuck plate 26. Since the outer recessed portion 52 and the recessed portion 60 are not in communication with each other, outside the isolation land 56,
In the areas not covered by the material GS, no air is sucked through the breathable part of the chuck plate 26 and thus the adsorption of the material GS is not impaired.

When the chuck means 4 is positioned in the material discharge area 14, the recess 60 is separated from the vacuum source 106 and the water supply source 108.
Be able to communicate with. Thus, water is caused to flow to the upper surface of the chuck plate 26 through the breathable portion of the chuck plate 26, and thus the material GL or GS on the chuck plate 26 is floated.

Referring again to FIG. 1, the material loading area 10
The material carrying-in means 18 arranged in association with the above is a cassette mounting table 110 on which a cassette capable of accommodating a plurality of plate-shaped materials GL (or GS) is mounted at intervals in the vertical direction. , The plate-shaped material receiving table 112 and the cassette mounting table 110
Plate material GL (or GS) from the cassette placed on top
And a supply mechanism 114 for supplying each of the above to the receiving table 112. The cassette mounting table 110, the cassette mounted on the cassette mounting table 110, and the supply mechanism 114 may be substantially the same as the well-known configuration generally used in a backside grinding machine for semiconductor wafers and the like. The description of the configuration and operation will be omitted. The material loading means 18 further includes a pivot arm 116. The swivel arm 116 reciprocates between a suction position shown by a solid line and a disengagement position shown by a two-dot chain line with a swivel axis extending substantially vertically (extending substantially perpendicular to the paper surface in FIG. 1) as a center. It is mounted so that it can be swiveled and swung, and is also vertically movable in a substantially vertical direction. At the free end of the swivel arm 116, a suction head 118, which may be of any suitable form, is provided. The adsorption head 118 is connected to a vacuum source and an air supply source, which may be an ordinary vacuum pump or an ejector, through a communication line including a switching valve (not shown), and the vacuum source or the air supply source is connected by the switching valve. Can be selectively communicated with. When the swivel arm 116 is positioned at the suction position shown by the solid line, the suction head 118 is positioned directly above the plate-shaped material GL (or GS) on the pedestal 112. In such a state, the suction head 118 is made to communicate with the vacuum source, thus the suction head 118 is
The plate-shaped material GL (or GS) on 12 is vacuum-adsorbed. Then
The revolving arm 116 is raised by a predetermined distance, then pivoted to a disengaged position indicated by a chain double-dashed line, and then lowered by a predetermined distance. As a result, the suction head 118 moves to the above-mentioned material loading area 10
Is located directly above the chuck means 4 located at. In such a state, the suction head 118 is separated from the vacuum source and communicated with the air supply source for some time,
Therefore, the plate-shaped material GL (or GS) is detached from the suction head 118 and placed on the chuck means 4. Thus, the plate-shaped material GL (or GS) is loaded onto the chuck means 4 in the material loading area 10. Thereafter, the swivel arm 116 is raised by a predetermined distance for the next loading of the plate-shaped material GL (or GS), then swung to the suction position shown by the solid line, and lowered by a predetermined distance.

Next, the cutting blade device 20 arranged in relation to the cutting work area 12 will be described. Referring to FIG. 5, the cutting blade device 20 includes a stationary support frame 120 arranged above the support base 2. A pair of guide rails 122 extending substantially vertically at a distance are fixed to the front surface of the support frame 120, and the movable support 124 is vertically movable in a substantially vertical direction on the pair of guide rails 122. Is attached to. On the front surface of the support frame 120, blade moving means 1 for moving the movable support 124 up and down.
There are also 26. The blade moving means 126 is a male screw rod that is rotatably mounted and extends substantially vertically.
128 and an electric motor 130 for rotating the male screw rod 128. The male screw rod 128 is screwed into a female screw hole (not shown) formed in the movable support member 124. Therefore, the forward and reverse rotation of the male screw rod 128 causes the movable support member 124 to descend and rise. . The movable support 124 has a shaft 132 extending substantially vertically.
The blade rotating means 134 is rotatably mounted and may also be an electric motor for rotating the shaft 132.
Is installed. The shaft 132 projects downward beyond the movable support 124, and a blade support 136 is fixed to the lower end of the shaft 132. Referring to FIG. 6 together with FIG. 5, on the lower surface of the blade support 136, two concentric blades, that is, an inner blade 138 having a relatively small diameter cylindrical shape, and a relatively large diameter. The outer blade 140 having a cylindrical shape is fixed. The blade support 136 has a plurality of cooling liquid ejection holes 142 for ejecting a cooling liquid such as water at the time of cutting by the inner blade 138 and the outer blade 140.
Are formed. Inner blade 138 that can be formed by combining diamond abrasive grains with metal or the like
The preferred construction of the outer blade 140 itself and its manufacturing method are described in detail in the specification and drawings of Japanese Patent Application No. 247749 in 1985 (see Japanese Patent Publication No. 3-10458). Are left to the above specification and drawings, and are omitted in the present specification. Although the inner blades 138 and 140 in the illustrated embodiment are both circumferentially continuous cylindrical, each of the inner blades 138 and 140 may, if desired, have a plurality of circumferentially spaced intervals. It can also consist of arcuate pieces.

Referring to FIG. 7 together with FIG. 5, in the cutting work area 12, the shaft 132 is rotated at a relatively high speed by the biasing of the blade rotating means 134, and thus the inner blade 138 and the outer side. The blade 140 is rotated at a relatively high speed. In addition, the blade moving means 126
Is urged to lower the movable support 124 at a relatively low speed,
Thus, the inner blade 138 and the outer blade 140 are lowered relatively slowly. Thus, as shown in FIG. 7, the inner blade 13 rotated at a relatively high speed.
8 and the outer blade 140 gradually act on the plate material GL from the upper surface of the plate material GL downward to cut the plate material GL. Therefore, the plate-shaped material GL is cut along the circular inner cutting line by the inner blade 138 and the outer blade 140.
Is cut along a circular outer cutting line. At the time of such cutting, a cooling liquid such as water is spouted from the cooling liquid spouting hole 142 (FIG. 6). As shown in FIG. 7, the inner blade 138 and the outer blade 140 are made of a plate-shaped material.
The GL can be lowered until it is completely cut. Plate material GL
Inner blade 13 protruding downward beyond the lower surface of
8 and the lower ends of the outer blades 140 enter the annular grooves 32 and 36 formed on the surface of the chuck plate 26 of the chuck means 4. On the other hand, if the plate-like material to be cut is a relatively small square, then relatively small diameter inner and outer blades are used, in which case the lower ends of the inner and outer blades are the chucks of the chuck means 4. Board 26
It enters into the annular grooves 30 and 34 instead of the annular grooves 32 and 36 formed in the surface of the. When the cutting of the plate material GL (or GS) is completed, the inner blade 138 and the outer blade 140
From the plate-shaped material GL (or GS).

If desired, the lowermost positions of the inner blade 138 and the outer blade 140, and thus the cutting depth of the plate material GL, may be
It is also possible to set such that some (for example, several μm) non-cutting portions remain on the lower surface of the GL. In this case, the non-cutting portion of the plate-shaped material GL is later broken by applying some force to the non-cutting portion. When an appropriate synthetic resin tape is attached to the back surface of the plate-shaped material GL, the tape is kept in an uncut state without being completely cut, thereby maintaining the integrity of the plate-shaped material GL. , Plate material
GL can also be completely cut without leaving a non-cut part at the bottom.

FIG. 8 shows a modification of the cutting blade device. The cutting blade device, generally designated by the numeral 150, comprises a stationary support frame 152 arranged above the support base 2. A pair of guide rails 154 extending substantially vertically with a space therebetween are fixed to the front surface of the support frame 152, and a movable support 156 is vertically movable in a substantially vertical direction on the pair of guide rails 154. Is attached to. The support frame 152
A blade moving means 158 for moving the movable support 156 up and down is provided on the front surface of the. This blade moving means 1
58 has a male screw rod 160 rotatably mounted and extending substantially vertically, and an electric motor 162 for rotating the male screw rod 160. The male screw rod 160 is screwed into a female screw hole (not shown) formed in the movable support 156, and thus the male screw rod 160 is provided.
The movable support 156 is lowered and raised by the forward and reverse rotations of. A pair of guide rails 164 extending in a substantially vertical direction with a space therebetween are also fixed in the movable support 156. An auxiliary support 166 is mounted on the pair of guide rails 164 so as to be vertically movable in a substantially vertical direction. Auxiliary moving means 168 for moving the auxiliary support 166 up and down is also provided in the movable support 156. The auxiliary moving means 168 has a male screw rod 170 rotatably mounted and extending substantially vertically, and an electric motor 172 for rotating the male screw rod 170. The male screw rod 170 is screwed into a female screw hole (not shown) formed in the auxiliary support body 166. Therefore, the normal rotation and the reverse rotation of the male screw rod 170 cause the auxiliary support body 166 to descend and rise. . Mounted on the auxiliary support 166 is a first rotating means 174, which may be an electric motor, and a shaft 176 extending substantially vertically downward from an upper end drivingly connected to an output shaft of the first rotating means 174. There is. The shaft 176 projects downward beyond the movable support 156, and a substantially disk-shaped inner blade support 178 is fixed to the lower end of the shaft 176.
Then, on the lower surface of the inner blade support 178, an inner blade 180 which may be substantially the same as the inner blade 138 (FIGS. 5 and 6) in the cutting blade device 20 described above.
Is stuck. In the lower part of the movable support 156,
A substantially cylindrical rotation member 182 is also rotatably mounted. The rotating member 182 projects slightly below the lower end of the movable support 156, and the annular connecting member 18 is provided at the lower end.
4 is fixed, and an annular outer blade support 186 is fixed to the lower end of the connecting member 184. An outer blade 188, which may be substantially the same as the outer blade 140 (FIGS. 5 and 6) in the cutting blade device 20 described above, is fixed to the lower surface of the outer blade support 186. Furthermore,
A rotary shaft 190 is rotatably mounted on the outer surface of the movable support 156, and second rotating means 192, which may be an electric motor drivingly connected to the shaft 190, is mounted on the outer surface. The shaft 190 is moved by the belt mechanism 194 into the rotating member 18
Driven to 2. Thus, when the second rotating means 192 is biased to rotate the shaft 190, the rotating member 182 is rotated and thus the outer blade 188 is rotated.

The operation and effect of the cutting blade device 150 as described above will be summarized and described as follows. Prior to the actual cutting operation, the auxiliary moving means 168 is biased to lower or raise the auxiliary support 166 as necessary, and thus the vertical position of the inner blade 180 with respect to the outer blade 188 is appropriately adjusted. The vertical adjustment position of the inner blade 180, for example, the lower end of the inner blade 180 is the outer blade 1
The lower end of 88 is made to substantially match (so that the cutting depth of the plate material GL (or GS) by the outer blade 188 and the cutting depth of the plate material GL (or GS) by the inner blade 180 are substantially the same. Position). Plate material GL
(Or GS) the amount of wear of the inner blade 180 and the amount of wear of the outer blade 188 by cutting is not necessarily the same, therefore, if the vertical position of the inner blade 180 can not be adjusted as necessary, the cutting work If the cutting depth of the plate-shaped material GL (or GS) by the inner blade 180 and the cutting depth of the plate-shaped material GL (or GS) by the outer blade 188 is set to a required value, the other will be changed from the required value. It fluctuates. However, in the cutting blade device 150 shown in FIG. 8, the inner blade 180 is adjusted by appropriately adjusting the vertical position of the inner blade 180 according to the wear amount of the inner blade 180 and the outer blade 188.
Cutting depth of plate material GL (or GS) and outer blade
Both the cutting depth of the plate-shaped material GL (or GS) by 188 can be set to required values.

To perform the cutting operation, the first rotating means 174 is urged to rotate the inner blade 180 at a relatively high speed and the second rotating means 192 is urged to rotate the outer blade 188.
Rotate at a relatively high speed. The direction of rotation of the inner blade 180 and the direction of rotation of the outer blade 188 may be the same, but are preferably opposite to each other. In addition, the blade moving means 158 is urged to lower the movable support 156 at a relatively low speed, and thus the inner blade 180 and the outer blade 188 are moved at a relatively low speed, as in the cutting blade device 20 described above. In addition, the inner blade 180 cuts the plate material GL (or GS) along the circular inner cutting line, and the outer blade 188 cuts the plate material GL (or GS) along the circular outer cutting line. In the case of such cutting,
For example, a cooling liquid such as water can be jetted from a cooling liquid jet hole (not shown) formed in the inner blade support 178 and / or the outer blade support 186. In the modification shown in FIG. 8, the lowering of the inner blade 180 and the lowering of the outer blade 188 are integrally performed during the cutting operation, but if desired, the inner blade 180 may be lowered during the cutting operation. The lowering and lowering of the outer blade 188 can also be performed separately and independently.
