DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for obtaining cutting execution data in a cutting apparatus and a cutting apparatus. More specifically, in a cutting device for half-cutting or cutting a work such as a laminated substrate such as a ceramic green sheet or a thin plate-like substrate, the cutting blade is controlled even if the cutting edge of the cutting blade is not parallel to the index table. The present invention also relates to a method for obtaining cutting execution data for half-cutting or cutting the work and a cutting device.

2. Description of the Related Art A cutting device for half-cutting a laminated substrate such as a ceramic green sheet or a thin plate before sintering in a grid pattern or the like is provided with a drive source for controlling a cutting blade in a vertical direction and a predetermined amount. It consists of a controllable cutting section for addressing and an index table on which a work is placed. Each time the cutting section is moved in a forward and backward direction (Y-axis direction) at a predetermined pitch, a drive source composed of a servomotor is driven to index. After half-cutting the work placed on the surface of the table into a band shape while leaving the peripheral portion, the index table is rotated by 90 degrees, and the cutting portion is similarly moved in the front-rear direction (Y-axis direction) at a predetermined pitch. Each time the drive source is driven, the work on the surface of the index table is similarly cut in half, and it is performed on both sides of the work. Divided after firing has been to obtain a rectangular chip. The reason for half-cutting or cutting while leaving the peripheral portion is that a mark for cutting is provided on the peripheral portion, and the mark remains on a product (rectangular chip) obtained by sintering. When a laminated substrate such as a ceramic green sheet or a thin substrate before sintering is cut in a grid pattern or the like, the above process is performed only from the surface side of the work. By the way, a very high degree of parallelism is required for the relationship between the cutting edge of the cutting blade and the surface of the index table. If the parallelism is deviated even in micron units, the depth of the half cut from the front side and the back side will not be uniform, and cracking, chipping, delamination etc. will occur when firing and cracking. In the case of a laminated substrate having a concave portion such as a saw filter on the surface side, the peripheral wall of the concave portion is formed by a dispersing force generated when the substrate is split because a half-cut is performed from a position close to the concave portion having a small bonding area between layers. Cracks occur in the portions, and delamination becomes prominent. In addition, even when cutting is performed completely, the cutting edge of the cutting blade partially collides with the surface of the index table, causing blade spilling.

Conventionally, as a method of obtaining the parallelism, a jack bolt is used as a mounting member for an index table on a table, and the index table is gradually lifted by the jack bolt, so that the cutting edge of the cutting blade and the table surface are removed. Since the parallelism is obtained while measuring a plurality of points with a micrometer, the work of assembling the index table to the table becomes very complicated and the assembling time is wasted.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to perform cutting even if the parallelism between the cutting edge of the cutting blade and the surface of the index table is not achieved. It is an object of the present invention to provide a method of obtaining cutting execution data in a cutting device for half-cutting or cutting a work by sometimes giving a degree of parallelism, and a cutting device used therefor.

[0005]

The technical means taken in order to solve the above-mentioned object is to control the tilt angle of the cutting blade in the cutting direction (X-axis direction) together with the drive source for controlling and moving the cutting blade in the vertical direction. A cutting unit having a means for enabling the control of the amount of movement in the front-rear direction (Y-axis direction), an index table on which the work is mounted, and a plurality of cutting edges in the cutting direction mounted on the index table and lowered by the cutting blade Using a jig which detects a point and is parallel to the index table surface in a direction (Y-axis direction) perpendicular to the cutting direction, descends from the origin position with the jig placed on the index table Detecting a plurality of points of the cutting edge in the cutting direction of the cutting blade, calculating the tilt angle data of the cutting blade in the cutting direction, and moving the cutting blade by a predetermined amount in a direction orthogonal to the cutting direction. The cutting edge of the cutting blade to be lowered from the point position is detected by the jig, the amount of data of the lowering of the cutting blade from the home position is processed, and the above-described process is similarly performed when the index table is rotated by 90 degrees. It is characterized by the following. Here, each of the cutting blade, its driving source, means for controlling the tilting angle of the cutting blade, the jig, and the index table constitute a fully closed circuit in cooperation with a control unit. The sensing part of the jig is movable parallel to the index table surface in the cutting edge blade direction (X-axis direction) on the index table surface and is artificial or mechanical in a direction perpendicular to the blade cutting direction (Y-axis direction). Or a contact member that can be moved in the blade direction as its sensing part, an optical sensor, or the like, and in the case of a contact member, a block member that is mounted in a direction orthogonal to the blade direction. In the case where the sensing unit is an optical sensor and has a top parallel to the surface of the index table, it is provided in a movable body that can move linearly in the direction of the blade that is open upward, and the movable body is orthogonal to the blade direction of the cutting blade. It is preferable to form the jig by forming it into a shape having an internal space of a desired width dimension that does not hinder the movement in the direction of movement.

According to this technical means, the jig is placed on the index table, the cutting blade is lowered from the origin position (top dead center), and the sensing part (contact body, optical sensor) of the jig is extended. If the cutting blade is lowered from the origin position by moving the cutting blade artificially or mechanically parallel to the direction, it can be detected at any position of the cutting edge.
In the case of an optical sensor, the amount of light received from the lower edge of the cutting edge). For this reason, for example, one end of the cutting direction is detected by a jig, and the data is transmitted (output) to a control unit serving as the center of the fully closed circuit. Subsequently, the sensing unit is connected to the other end of the cutting edge, for example, in the cutting direction. The corresponding edge is moved to detect the other end, and the data is transmitted (output) to the control unit in the same manner. Based on the data, the relative parallelism between the cutting edge of the cutting blade and the surface of the index table is determined. The correction amount of the blade edge (incorrect angle), that is, the tilt angle data of the cutting blade is obtained. Note that the detection positions described above need not be at both ends of the blade edge in the blade length direction,
A point is enough. In this case, the tilt angle data of the cutting blade may be obtained by a trigonometric function based on the setting of the length of the cutting blade in the blade passing direction. Next, the cutting blade is moved in the front-rear direction (Y-axis direction) by a predetermined amount, the cutting blade is lowered from the origin position, detected by a contact body or an optical sensor, and each data is moved by a predetermined pitch. It is stored as a parameter of the cutting blade descending amount when the work is half-cut or cut by descending from the origin position each time. Each time the control unit moves by a predetermined pitch, the control unit lowers from the origin position and performs arithmetic processing on the amount of descent of the cutting blade when performing half cutting or cutting of the work. The tilt angle data and the descending amount data are used as execution data when half-cutting or cutting the work placed on the index table before rotating by 90 degrees. In the same manner, the index plate is rotated by 90 degrees, and in the same process, the tilt angle data and the descending amount data of the cutting blade are calculated by the control unit.
Data is used as execution data. Incidentally, in claim 1, ... parallel to the index table surface in a direction (Y-axis direction) orthogonal to the blade-extending direction ... means an index table in a direction orthogonal to the blade-extending direction, such as the contact body. It has an apex parallel to the surface or is provided in a movable body that can move linearly in the direction of the upper open blade, such as an optical sensor, and moves the movable body in a direction perpendicular to the blade extending direction of the cutting blade. It does not only refer to forming a jig by forming it into a shape having an internal space of a desired width dimension that does not hinder movement, but artificially or in the blade width direction of the block member as in the case of using the block member. In addition to mechanical translation, it also refers to parallel translation by a predetermined amount artificially or mechanically in a direction perpendicular to the blade length direction. In the case of this block member as well, each time the cutting edge that descends the cutting blade from the origin position is detected from the origin position and the data is moved to the predetermined pitch by the same pitch as the contact body and the optical sensor, the data is moved down from the origin position to the predetermined pitch. What is necessary is just to store it as a parameter of the cutting blade lowering amount when the work is half-cut or cut.

A drive source for controlling the vertical movement of the cutting blade and a means for controlling the tilting angle of the cutting blade in the blade extending direction (X-axis direction) are provided, and the amount of movement in the front-rear direction (Y-axis direction) is controlled. Using a possible cutting unit, an index table for mounting the work, and a jig for detecting a plurality of cutting edges in the cutting direction of the cutting blade mounted and lowered on the index table, and mounted on the index table. The jig detects a plurality of points of the cutting edge in the cutting direction of the cutting blade descending from the origin position, calculates the tilt angle data of the cutting blade in the cutting direction, and calculates the tilt angle of the cutting blade with the tilt angle data in the cutting direction. Each time the blade is moved by a predetermined amount in the direction (Y axis direction) perpendicular to the axis, the cutting edge is raised and lowered so that the cutting edge makes line contact with the index table, and cuts from the origin to the bottom dead center The lowering amount data processing, but the process effective even if the index table to perform as well when pivoted 90 degrees. In this case, as the sensing portion, the block member that is manually or mechanically moved in the blade direction, the contact body or the optical sensor that can be linearly controlled in the blade direction is moved artificially or mechanically in the blade direction in addition to the blade. A probe that detects the amount of displacement upon contact can be used.

According to the above technical means, the tilt angle data before the index table is rotated by 90 degrees is detected by a jig (block member, contact body, optical sensor, probe, etc.), and the parameter is determined by the jig. After removal, the cutting edge of the cutting blade is made parallel to the index table with the tilt angle data, and then the entire cutting edge is brought into line contact with the surface of the index table from the origin position while moving the cutting blade forward or backward by a predetermined amount. To calculate the driving force of the driving source from the origin position. The control unit calculates the descending amount data of the cutting blade when half-cutting or cutting the work using the parameters. The tilt angle data and the descending amount data are used as execution data when executing half-cutting or cutting of a work placed on the index table before rotating by 90 degrees. The same operation is performed after the index table is turned by 90 degrees, and the tilt angle data and the descending amount data at that time are used as execution data after the index table is turned by 90 degrees.

The index table contains 90
It is further preferable to have a positioning means for positioning the jig at each position before and after the rotation by 90 degrees so that the jig can be inserted and removed.

That is, the jig is accurately positioned on the surface of the index table before rotation or on the surface of the index table after rotation, and the positioning means is pulled out during half-cutting or cutting, and does not hinder cutting.

A drive source for controlling the vertical movement of the cutting blade and means for controlling the tilt angle of the cutting blade in the blade extending direction (X-axis direction) are provided in the front-rear direction (Y-axis direction).
Using a cutting section in which the amount of movement can be controlled, and an index table on which the work is placed, the cutting blade is tilted from the origin position to the one side in the blade crossing direction and the other side at the same angle. Lower the cutting blade so that the cutting edge on one end side and the cutting edge on the other end side of the cutting blade are respectively in contact with the surface of the index table, and calculate the amount of descent from both origin positions by the rotation amount of the drive source to calculate the surface of the index table. The tilt angle data of the cutting blade in the cutting direction with respect to is calculated, and the cutting edge linearly contacts the index table every time the cutting blade inclined with the tilt angle data is moved by a predetermined amount in the direction orthogonal to the cutting direction (Y-axis direction). To move the index table 90 degrees by rotating the index table by calculating the descent amount data of the cutting blade from the origin position to the bottom dead center. Those may be carried out similarly even when.

According to this technical means, the cutting blades are respectively lowered from the origin position (top dead center position) by inclining at the same angle in both directions in the blade passing direction, and the amount of descent from both origin positions is determined by the rotation amount of the drive source. Then, the control unit performs arithmetic processing, whereby tilt angle data can be obtained. Then, based on the tilt angle data, the cutting blade is moved forward and backward by a predetermined amount (Y-axis direction).
Similarly, each time the workpiece is moved to the position, it is lowered from the origin position to bring the cutting edge into line contact, and is lowered from the origin position and stored in the control unit as a parameter of the amount of descending of the cutting blade when half-cutting or cutting the work. The control unit performs the arithmetic processing as the data of the amount of descent of the cutting blade when cutting or half-cutting the work by descending from the origin position every time the control unit moves at a predetermined pitch with the parameter. The tilt angle data and the descending amount data are used as execution data when executing half-cutting or cutting of a work placed on the index table before rotating by 90 degrees. The same applies after the index table is turned by 90 degrees, and the tilt angle data and the descending amount data at that time are used as execution data after the index table is turned by 90 degrees. The same as the item.

The jig is used as a means for detecting blade spillage or wear of the cutting edge of the cutting blade during the half-cutting or cutting of the work.
If the transmission means for transmitting to the operator when the blade spill or wear exceeds the permissible range is more preferable, it is very preferable to prompt the replacement time of the cutting blade.

As a cutting device, a tilting table having a cutting blade is provided on a column which can be controlled in the front-rear direction so as to control the tilting angle of the cutting blade in the blade crossing direction. The gist of the invention is that the vertical movement of the cutting blade with respect to the tilting table is controlled by a possible drive source.

The procedure for obtaining cutting execution data using the cutting device A and the jig 3 configured as described above will be described in order. First, the procedure will be described. The jig 3 is placed on the surface of the index table 2 with the side surfaces of the table 13 abutted and positioned. The jig 3 becomes parallel to the blade extending direction (X-axis direction) of the cutting blade S by the positioning function of the positioning means 4, and the cutting blade S
Is moved right above the jig 3, the contact body 53, which is a sensing unit, is in a plan view form in a direction (Y-axis direction) orthogonal to the blade extending direction of the cutting blade S. Then, the contact body 53 is controlled and moved so as to be located, for example, immediately below one end side in the blade extending direction (X-axis direction), and in that state, the cutting blade S is lowered from the origin position (top dead center) to change the cutting edge to the contact body. 5
The contact body 53 is brought into contact with the top of the contact member 3 to detect the amount of descent from the origin position, transmit (output) the data to the control unit C, and subsequently control and move the contact body 53 so as to correspond to the other end in the blade length direction.
The blade tip descending from the origin position is brought into contact with the top of, the amount of the depression is detected, and the data is transmitted (output) to the control unit (see FIG. 4). The control unit C calculates (first tilt angle data) a correction amount (out-of-order angle) for the relative parallelism between the cutting edge of the cutting blade S and the index table 2 based on the two data (first tilt angle data) and stores it in the RAM. . Next, the cutting blade S is moved in the front-rear direction (Y-axis direction) by a predetermined amount, and is brought into contact with the top of the contact body 53 each time the cutting blade S is lowered from the origin position. The lowering amount is transmitted (output) to the controller C (see FIG. 5). Control unit C
Calculates descent amount data (first descent amount data) for half-cutting or cutting a work (not shown) while moving in the Y-axis direction at a predetermined pitch using the data as a parameter, and this is also stored in the RAM. I do. The surface of the index table 2 is a one-way inclined plane even though the surface of the index table 2 is not parallel to the cutting edge of the cutting blade S. Therefore, the cutting blade S
Is moved in the forward and backward directions (Y-axis direction) by a predetermined amount, and each time the cutting blade S is lowered from the origin position, the cutting blade S is brought into contact with the top of the contact body 53, and each time the cutting blade S is lowered from the origin position (rotation of the servo motor) The data obtained by transmitting (outputting) the amount to the control unit C can be used as a parameter of the descending amount data. The above process is performed by using an index table 2
Is performed in the same manner when the data is rotated by 90 degrees, and the second tilt angle data and the second descent amount data are stored in the control unit (RAM). Needless to say, the jig 3 is positioned at the position indicated by the two-dot chain line in FIG. 3 to rotate the index table 2 by 90 degrees, or otherwise similarly positioned on the surface of the index table 2 rotated by 90 degrees. .

At the time of executing a half-cut or cutting, the control unit C controls the cam 211 based on the first tilt angle data.
c ′ so that the tip of the cutting blade S is parallel to the surface of the index table 2.
After tilting 1 in the blade cutting direction (X-axis direction), the brake mechanism 211b is controlled to maintain the tilt angle.
Each time the control unit C moves the cutting unit 1 in the Y-axis direction at a predetermined pitch, the control unit C adds the first descent amount data to the work (not shown) placed on the index table 2 from the top of the contact 53. The height data up to the half-cut position is added, the cutting blade S is lowered from the origin position, and the work is half-cut. Of course, in the case of cutting instead of half cutting, the height data from the top of the contact 53 to the surface of the index table 2 is added to the descending amount data and executed. At the time of executing the half-cut after the rotation by 90 degrees, and at the time of performing the cutting, the contact 53
Half-cut is executed by adding height data from the top to the half-cut position of a work (not shown) placed on the surface of the index table 2, and in the case of cutting instead of half-cut, the second Contact 5
3 is executed by adding height data from the top to the index table 2. In the half-cut, the work (not shown) is turned over and repeated as described above.

Next, a second embodiment will be described. In this embodiment, the sensing section 53 is an optical sensor for detecting the position of the cutting edge of the cutting blade S. The sensing unit 53 is provided in a movable body 53a having an upward open type (U-shaped upward), and the movable body 53a is
The servo motor 2 has an internal space 53b having a desired width dimension which does not hinder the movement of the blade edge in a direction (Y-axis direction) orthogonal to the blade-over direction.
The third embodiment is the same as the first embodiment except that the upper surface of the support base 13 can be linearly controlled and moved by a ball screw mechanism 43 using a drive source 3 as a drive source.

The optical sensor 53 is disposed along one inner side surface of the internal space 53b of the moving body 53a.
A light emitting element 63 is provided on the other inner side surface of the inner space 53b of FIG. I have.

The width dimension of the internal space 53b is such that the cutting blade S is moved in the front-rear direction (Y-axis direction) by a predetermined amount.
Each time it is lowered from the origin position, it is used as a space for moving the cutting blade S when transmitting (outputting) the descending amount from the origin position to the control unit C each time.

The procedure for obtaining the cutting execution data using the cutting device A and the jig 3 is different from that of the first embodiment in that the light is detected by the contact with the contact body as the sensing unit. The description is omitted because it is the same except that the change is detected.

The third embodiment will be further described. This embodiment shows a method of obtaining cutting execution data obtained by using a block member for a jig (specifically, a sensing unit 53) 3. I have. In this embodiment, a block member, for example, a block member 53 having a bottom surface as a planar seating surface.
The index table is positioned so as to face the both ends of the cutting edge of the cutting blade S in each state before and after rotating by 90 degrees in the same manner as in the first and second embodiments. A plurality of positioning means (positioning pins) 4 on the surface of 2
Can be positioned. Then, the cutting blade S is lowered from the origin position (top dead center) in a state where the block member 53 is artificially moved to one end side in the blade extending direction (X-axis direction) and positioned, and the cutting edge is blocked. By contacting the top of the member 53, the amount of descent from the origin position is detected, the data is transmitted (output) to the control unit C, and subsequently, the data is artificially moved so as to correspond to the other end in the blade length direction. In this state, it is lowered from the origin position and is similarly brought into contact with the top of the member 3 to detect the amount of lowering and transmit (output) the data to the controller C (FIG. 8). The control unit C performs the first,
Similar to the second embodiment, a correction amount (out-of-order angle) for the relative parallelism between the cutting edge of the cutting blade S and the index table 2 is calculated based on both data (the index table 2 is rotated by 90 degrees). The first tilt angle data before and the second tilt angle data after being rotated by 90 degrees are stored in the RAM. And the block member 53
And a plurality of positioning means (positioning pins) 4
So that the cutting blade S tilted with the first tilt angle data and the second tilt angle data is moved in a predetermined amount in the front-rear direction (Y-axis direction) so as to come into line contact with the surface of the index table 2. The amount of lowering of the cutting blade S from the origin position to the bottom dead center (surface contact with the surface of the index table 2) by ascending and descending is calculated from the rotation amount of the drive source 31c from the origin position to the bottom dead center. The obtained data is stored in the control unit C as a parameter of the cutting blade descending amount at the time of executing the half cutting or cutting of the work by lowering each time the data is moved in the Y-axis direction for a predetermined pitch (FIG. 9). The control unit C determines the first descent amount data of the cutting blade,
Are respectively processed. At the time of performing a half cut or cutting (when executing before rotating the index table 2 by 90 degrees), the control unit C controls the cam 211c ′ based on the first tilt angle data to perform cutting. Blade S
After the tilting table 21 is tilted in the blade extending direction (X-axis direction) so that the blade edge of (1) is parallel to the surface of the index table 2, the brake mechanism 211b is controlled to maintain the tilt angle. Each time the control section C moves the cutting section 1 in the Y-axis direction at a predetermined pitch, the index table 2 is obtained from the first descent amount data.
The half-cut position is subtracted from the work (not shown) placed on the workpiece, and the cutting blade S is lowered to half-cut the work. Of course, in the case of cutting instead of half-cutting, the cutting is performed with the above-mentioned descent amount data. At the time of executing the half-cut and the cutting after the 90-degree rotation, the same operation is performed using the second tilt angle data and the second descending amount data.

Next, although not shown, a fourth embodiment will be described. This embodiment is similar to the first embodiment and the second embodiment.
Instead of using the jig 3 to obtain the first descent amount data and the second descent amount data of the embodiment, the jig 3 is removed. The cutting blade S tilted with the first tilt angle data and the second tilt angle data is moved up and down so as to come into line contact with the surface of the index table 2 and is moved from the origin position to the bottom dead center (the surface of the index table). Is calculated by the rotation amount of the driving source 31c until the data obtained from the origin position to the bottom dead center is moved in the Y-axis direction by a predetermined pitch. It is stored in the control unit C as a parameter of the cutting blade at the time of executing the lowering and half-cutting or cutting the work. The control unit C calculates the first descent amount data and the second descent amount data. Since it is the same as the above-described first and second embodiments except for the point described above, a specific description will be omitted with reference to the drawings.

Although not shown in the fifth embodiment, the sensing section 53 may be a probe that contacts the cutting edge of the cutting blade S and detects the amount of displacement. In the case of this embodiment, the mounting table 4 of the first embodiment is used.
3, a probe serving as a sensing unit is provided so as to be linearly movable, and tilt angle data and descent amount data are obtained in the same manner as in the third and fourth embodiments.

Also, the jig 3 described in the first, second, fourth, and fifth embodiments can cut or cut a workpiece (particularly, a laminated substrate such as a ceramic green sheet having an electrode circuit). It can be used as a means for detecting blade spillage at the cutting edge of the cutting blade S during the work. In this case, the positioning means 4 positions the jig 3 in the cutting direction (X-axis direction) of the cutting blade S, and moves the sensing portion 53 linearly by a predetermined amount in the cutting direction S (X-axis direction). The blade edge is detected over the entire length while being lowered from the origin position. At this time, the reference data stored in the RAM of the control unit C is compared with the change data of the rotation amount of the driving source until the blade becomes unusable. A judgment circuit for judging whether or not the cutting blade S has spilled or worn is built in the control unit C, and the judgment can be made by that. Of course, the transmission means D is linked to the control unit C, and when the blade is spilled or worn out to an allowable range or more, the obtained product is yielded. I have to do it. As a transmission method, a method that appeals to sight and hearing, such as a warning sound, a lamp, and a buzzer, is preferable. By this transmission, the replacement of the cutting blade S is promoted, and the half-cut and the cutting with high accuracy can be performed. Inspection for this blade spill (including wear) is performed periodically.

From the (dead point), both ends of the cutting edge S are brought into contact with the surface of the index table 2, and the control unit C calculates the amount of descent from both origin positions by the amount of rotation of the drive source 31c, thereby converting the tilt angle data. obtain. Then, every time the cutting unit S having the cutting blade S is moved in the Y-axis direction by a predetermined amount after the cutting blade S is tilted with the tilt angle data, the cutting blade S is similarly moved from the origin position (top dead center position). Is lowered to bring the cutting edge of the cutting blade S into line contact, and is lowered from the origin position, and is stored in the control unit C as a parameter of the descending amount of the cutting blade S when the work is half-cut or cut (see FIG. 11). . The control unit C performs an arithmetic process as the descending amount data of the cutting blade S at the time of cutting or half-cutting the work by descending from the origin position every time the control unit C moves in the Y-axis direction at a predetermined pitch. In the index table 2, 90
The tilt angle data and the descent amount data are obtained before and after the 90-degree rotation.
