Description

  The present invention relates to an apparatus for breaking a brittle material substrate, and more particularly to the attachment of the break blade.

  A brittle material substrate (for example, a glass substrate or a ceramic substrate) or a thin film layer or thick film on which a scribe line is formed at a planned dividing position by a tool such as a scribing wheel or a diamond point or by laser processing in advance. An apparatus that divides (breaks) an object to be divided such as a laminate formed by laminating layers along the scribe line is already known (see, for example, Patent Document 1).

Generally speaking, the breaking apparatus 100 brings the cutting object 1 into contact with the parting target position of the parting target W supported downward by the support 2 and further depresses the parting target W with the cutting edge 1a of the breaking blade 1. It is an apparatus to break up (break). The break blade 1 is in the form of a plate having a uniform thickness except in the vicinity of the cutting edge 1a.

  The object to be divided W is, for example, a glass substrate or a ceramic substrate, or a laminate in which various thick film layers or thin film layers are laminated thereon, and is usually at a position to be divided on the one main surface Wa side. A scribe line SL is formed in advance. In addition, a vertical crack may extend from the scribe line SL toward the other main surface Wb.

  The division in the breaking apparatus 100 is carried out with the scribe line SL of the other main surface Wb placed on the support 2 in such a manner that the main surface Wa on which the scribe line SL is formed is brought into contact with the support 2. The break blade 1 can be pressed down while bringing the cutting edge 1a of the break blade 1 into contact with the corresponding cutting scheduled position. In such a case, the break blade 1 is used by being lifted and lowered by a lifting mechanism (not shown) in a state of being attached to an attached portion 20 (see FIG. 3 and the like) not shown in FIG. As the cutting edge 1a wears, the consumable is replaced with a new one at an appropriate timing. In this Embodiment, the attachment aspect at the time of attaching the break blade 1 to the break apparatus 100 becomes a characteristic thing. Hereinafter, this point will be described in detail.

<Cartridge for break blade>
FIG. 2 is an external perspective view of the break blade cartridge 10 in which the break blade 1 is fixedly held.

  In the conventional breaking device, the breaking blade is directly attached to and detached from the device, but in the breaking device 100 according to the present embodiment, as an alternative aspect, the breaking blade 1 is previously The break blade cartridge 10 is fixedly held by the break blade cartridge 10, and the break blade cartridge 10 formed by fixing and holding the break blade is detachable from the break device 100.

  As shown in FIG. 2, the break blade cartridge 10 includes a cartridge base (base member) 11 and a break blade pressing plate (hereinafter also simply referred to as a pressing plate) 12. Further, the cartridge base 11 has a clamping part 11A mainly responsible for clamping the break blade 1 and an attachment part 11B mainly responsible for attaching the break device 100 to the attached part 20.

  The cartridge base 11 (more specifically, the holding portion 11A) and the pressing plate 12 are fixed in a state in which the break blade 1 is held therebetween in a mode in which only the vicinity of the cutting edge 1a is exposed in the entire blade passing direction. It is screwed by a screw 13. The break blade 1 according to the present embodiment has a through-hole through which the fixing screw 13 passes, although the illustration is omitted in order to realize the clamping and fixing in such a mode. In the present embodiment, the case where screwing is performed by the fixing screw 13 at three fixing points separated from each other in the blade passing direction of the break blade 1 (that is, when the three fixing screws 13 are used) is illustrated. However, the number of fixing points by the fixing screw 13 is not limited to this.

  More specifically, the cartridge base 11 has an L-shaped cross section perpendicular to the longitudinal direction because the sandwiching portion (first portion) 11A and the attachment portion (second portion) 11B are perpendicular to each other. I am In the cartridge base 11 (also in each of the holding portion 11A and the mounting portion 11B), or in the pressing plate 12, the blade passing direction of the break blade 1 at the time of holding and fixing the break blade 1 is the longitudinal direction It has become.

  As described above, the clamping portion 11A and the attachment portion 11B are perpendicular to each other, so that in the cartridge base 11, the surface 11a of the clamping portion 11A and the surface 11b of the attachment portion 11B are orthogonal to each other at the end portions. Become. When the break blade 1 is sandwiched and fixed to the break blade cartridge 10, the surface 11 a becomes a sandwiching surface that sandwiches the break blade 1 with the pressing plate 12. On the other hand, an end of the breaking blade 1 opposite to the cutting edge 1a of the breaking blade 1 and an end face of the pressing plate 12 perpendicular to the holding surface for holding the breaking blade 1 abut on the surface 11b.

  At one longitudinal end of the surface 11a of the holding portion 11A, a break blade positioning pin 14a and a pressing plate positioning pin 14b are erected perpendicularly to the surface 11a. The positions of the break blade positioning pins 14a and the holding plate positioning pins 14b are arranged on the lower side when the cartridge base 11 is placed on the fixing jig 200 of the break blade 1 in the manner described later. It is determined to be located in

  When the break blade 1 is fixed and held (sandwiched) in the break blade cartridge 10, the break blade 1 is brought into contact with the surface 11a on one side, and is brought into contact with the surface 11b at the end opposite to the cutting edge 1a. And the one end part of a blade crossing direction is made to contact | abut with the positioning pin 14a for break blades. Further, the holding plate 12 has two surfaces perpendicular to each other in contact with the break blade 1 and the surface 11b of the cartridge base 11, and one end face 12a in the blade cross direction is a positioning plate 14b for holding plate and It is made to abut. The one end face 12a has a cutout 12b so that interference does not occur between the holding plate 12 and the positioning pin 14a for the breaking blade when the pressing plate 12 is used for fixing and holding the breaking blade 1. It will be provided.

  Fixing with the fixing screw 13 while observing these abutting states allows the break blade 1 to be fixed and held by the break blade cartridge 10 always in the same posture, even if it is replaced. Details of the attachment of the break blade 1 in the break blade cartridge 10 will be described later.

  The break blade cartridge 10 is manufactured so that the upper surface 11c of the cartridge base 11 serving as the upper surface of the break blade 1 and the blade edge 1a are parallel to each other in a state where the break blade 1 is fixedly held. This contributes to labor saving of attachment work when the break blade cartridge 10 is attached to the break device 100.

  Moreover, in the cartridge base 11, the attachment part 11B is extended rather than the clamping part 11A in the both ends of the longitudinal direction. The extending portion is a supported portion 11E that is supported by the attached portion 20 when the break blade cartridge 10 is attached to the attached portion 20.

  In addition, a pair of locking portions 15 are provided on the surface 11d of the attachment portion 11B parallel to the surface 11a of the sandwiching portion 11A in a manner of being separated from each other in the longitudinal direction of the attachment portion 11B. The locking portion 15 is a positioning portion used for restricting the mounting position in the longitudinal direction when the break blade cartridge 10 is mounted to the mounted portion 20. The locking portion 15 is provided so as to protrude perpendicularly to the surface 11d and to have a groove portion that is parallel to the surface 11d and has a U-shape in sectional view.

<Mounting of cartridge>
Next, an aspect in which the above-described break blade cartridge 10 is attached to the mounting portion 20 of the break apparatus 100 will be described. In the following description relating to this aspect, unless otherwise specified, the break blade cartridge 10 is configured to hold the break blade 1 in advance in the above-described manner.

  FIG. 3 is a perspective view showing a state in which the break blade cartridge 10 holding the break blade 1 fixedly attached to the mounting portion 20 of the break apparatus 100 is viewed obliquely from below. 4, 6, and 8 are a front view, a bottom view, and a side view, respectively, of the vicinity of the attached portion 20 in the attached state, and FIGS. 5, 7, and 9 are respectively FIGS. 4 and 6. FIG. 9 is a front view, a bottom view and a side view showing a state in which the break blade cartridge 10 formed by holding and fixing the break blade 1 virtually from the attachment state shown in FIG. 8 is excluded. 3 to 9, in the horizontal plane, the longitudinal direction of the breaking blade 1 in the state where the breaking blade cartridge 10 is attached to the mounting portion 20 is taken as the X axis direction, and the vertical direction is taken as the Y axis direction, In the horizontal plane, right-handed XYZ coordinates are given with the direction perpendicular to the X-axis direction being the Z-axis direction.

  In the present embodiment, the term “horizontal” is used in a literal sense, that is, as a term meaning a direction or a plane perpendicular to the direction in which gravity acts, If it is parallel to the upper surface of the support 2, it can be regarded as “horizontal”.

  The attached portion 20 to which the break blade cartridge 10 is attached includes a pair of support portions 21 that support the break blade cartridge 10, a pair of clamp portions 22 that clamp and fix the break blade cartridge 10, and the attached portion 20. A horizontal adjustment unit 23 that adjusts the horizontal posture, two reference surfaces 24a and 24b that are perpendicular to each other, and a pair of horizontal positioning units 25 are mainly provided. The reference surface 24b is provided so as to be parallel to the XY plane (and therefore perpendicular to the Z-axis direction), and serves as a reference surface and a contact surface of the break blade cartridge 10 in the Z-axis direction.

  The pair of support portions 21 are provided separately from each other in the X-axis direction, and when the break blade cartridge 10 is attached to the attachment portion 20, the pair of support portions 11E provided at both end portions of the attachment portion 11B. Are placed on each of them, thereby supporting the break blade cartridge 10 downward. In FIG. 8 and FIG. 9, in order to help the understanding of the configuration, a support portion which is originally on the near side in the drawing view and extends in the Z-axis direction and should support the supported portion 11E. Illustration of 21 is omitted.

  The pair of clamp portions 22 are spaced apart from each other in the X-axis direction, and each is a portion that clamps and fixes the break blade cartridge 10 with the reference surface 24b in the Y-axis direction.

  More specifically, the pair of clamp portions 22 are respectively a contact portion 22a that contacts the front surface 12c of the pressing plate 12 of the break blade cartridge 10 at the time of clamp fixing, and a rotation center of the clamp handle 22b. And a clamp mechanism 22d for moving the abutting portion 22a back and forth in the Z-axis direction according to rotation in the ZX plane (see FIG. 6). 6 and 7, in order to facilitate understanding of the configuration, one contact portion 22a that should originally be in contact with the pressing plate 12 is not shown.

  Specifically, with the supported portion 11E of the break blade cartridge 10 supported by the pair of support portions 21, the contact portion 22a is rotated by rotating the clamp handle 22b in the direction indicated by AR1 in FIG. Contacts the front surface 12 c of the pressing plate 12 of the break blade cartridge 10. As a result, a state in which the break blade cartridge 10 is fixedly held to the attached portion 20 is realized. With the fixing and holding, the back surface 11e of the break blade cartridge 10 comes into contact with the reference surface 24b, so that the positioning in the Z-axis direction is performed.

  When the clamp handle 22b is rotated in the direction indicated by AR2 in FIG. 6, the contact state of the contact portion 22a with the front surface 12c is released.

  Further, the horizontal adjustment portion 23 is for adjusting the horizontal posture of the attached portion 20 prior to the attachment of the break blade cartridge 10. In the attached portion 20, prior to the attachment of the break blade cartridge 10, the reference surface 24 a and the support portion 21 are in a horizontal state in advance by adjustment in the horizontal adjustment portion 23.

  Further, the pair of horizontal positioning portions 25 are provided in association with the respective clamp portions 22, and the break blade in the horizontal direction (X-axis direction) when the break blade cartridge 10 is attached to the attached portion 20. This is a part for regulating the position of the cartridge 10 for use.

  More specifically, each of the pair of horizontal positioning portions 25 is a ball plunger provided so as to protrude in the −Z-axis direction from the side of the clamp mechanism 22d of the clamp portion 22, and a pair of horizontal positioning portions in the X-axis direction. The separation distance of the portion 25 is the same as the separation distance of the pair of locking portions 15 in the attachment 11 </ b> B of the break blade cartridge 10.

  At the tip of each horizontal positioning portion 25 that is a ball plunger, there is provided a spherical projection internally connected to a spring (elastic body) (not shown). On the other hand, as described above, each locking portion 15 forms a groove. The locking portion 15 and the horizontal positioning portion 25 are in a state where the groove portion of the locking portion 15 is engaged with the protrusion at the tip of the horizontal positioning portion 25 (the state where the protrusion at the tip of the horizontal positioning portion 25 is locked in the groove portion) ), The projection at the tip of the horizontal positioning portion 25 applies a biasing force to the locking portion 15. Moreover, since the locking portion 15 is U-shaped in cross section, the biasing force is strengthened by the displacement of the locking portion 15 and the spring in the horizontal positioning portion 25 being contracted when it is likely to be separated. Therefore, once the engaged state (locked state) is generated, it is maintained unless the break blade cartridge 10 is moved in the + Z-axis direction. As a result, the arrangement position of the break blade cartridge 10 in the X-axis direction is restricted.

  When attaching the break blade cartridge 10 to the attachment portion 20 of the break device 100 having the above-described configuration, first, the horizontal of the reference surface 24a and the support portion 21 is secured in advance, and the clamp handle 22b is The pair of supported portions 11E of the break blade cartridge 10 is fitted between the corresponding support portion 21 and the reference surface 24a in the state rotated in the direction indicated by the arrow AR2, and the pair of supported portions 11E correspond. It is supported by the support part 21. Thereby, positioning in the Y-axis direction (vertical direction) is performed. In the case of such support, it is preferable that the approximate position of the locking portion 15 in the X-axis direction is matched with the position of the horizontal positioning portion 25 in the X-axis direction.

  Subsequently, the clamp handle 22b is pivoted in the direction indicated by the arrow AR1. As a result, each of the pair of clamp mechanisms 22d is caused to advance the contact portion 22a in the retracted state in the −Z-axis direction. As a result, the back surface 11e of the break blade cartridge 10 contacts the reference surface 24b, Furthermore, the break blade cartridge 10 is clamped and fixed between the contact portion 22a and the reference surface 24b. In addition, with the clamping operation, the pair of locking portions 15 of the break blade cartridge 10 arranged in the vicinity of the corresponding pair of horizontal positioning portions 25 in advance are engaged with the corresponding pair of horizontal positioning portions 25, respectively. Match. By these operations, positioning in the Z-axis direction (insertion direction) and the X-axis direction (blade spanning direction) is performed.

  When the clamping operation is completed, the break blade cartridge 10 is fixedly attached to the attached portion 20, that is, the break blade 1 is fixed to the break device 100 in the aspect according to the present embodiment. .

  When the break blade cartridge 10 is removed, it can be easily removed by rotating the clamp handle 22b again in the direction indicated by the arrow AR2 to release the clamped state.

  As described above, according to the present embodiment, the break blade cartridge 10 in which the break blade 1 is fixedly held in advance is to be attached to and detached from the break device 100, and the attachment / detachment is performed by the clamping operation and the releasing operation. Since it can be performed, the break blade 1 can be attached and detached from the break device 100 quickly and easily as compared with the conventional mode in which the break blade itself is directly attached and detached.

  Further, as described above, in the break blade cartridge 10, the break blade 1 is fixed in advance in such a manner that the upper surface 11c of the cartridge base 11 serving as the upper surface thereof and the cutting edge 1a of the break blade 1 are parallel to each other. And when the break blade cartridge 10 is attached to the attachment portion 20 of the break apparatus 100, the support portion 11E is placed on the support portion 21 of the attachment portion 20, which has been made horizontal in advance. It has become. That is, the break blade cartridge 10 is horizontally supported by the support portion 21. Therefore, whenever the break blade cartridge 10 is attached to the attached portion 20, the break blade 1 (more specifically, the blade edge 1a) is in a horizontal state. In other words, in the break device 100 according to the present embodiment, as long as the support portion 21 is in a horizontal state, the break blade 1 can be placed horizontally as long as the break blade cartridge 10 is attached without special adjustment. It can be attached.

  Moreover, in the clamping operation, the supported portion 11E is supported by the support portion 21 and the back surface 11e is in contact with the reference surface 24b, so the mounting position of the break blade cartridge 10 in the vertical direction and in the fitting direction is always the same. It becomes.

  Moreover, since the latching | locking part 15 engages with the horizontal positioning part 25 with a clamp operation | movement, the cartridge 10 for break blades always becomes the same also about the attachment position of a blade crossing direction.

  That is, in the break device 100 according to the present embodiment, as long as the break blade cartridge 10 is clamped and fixed by the clamp portion 22, the break blade cartridge 10 is always at the same position without special positioning adjustment. Will be fixed. That is, even if the break blade 1 is replaced, the mounting position is easily reproduced. This means that in the break device 100 according to the present embodiment, it is not necessary to adjust the position of the break blade 1 after the break blade 1 is replaced, and a break can be performed by the new break blade 1 immediately after the replacement. Means.

  Furthermore, if a plurality of break blade cartridges 10 are prepared, the break blade 1 can be attached to another break blade cartridge 10 while using one break blade cartridge 10. Therefore, the time required to replace the break blade 1 can be further shortened.

  As described above, according to the present embodiment, the attachment of the break blade to the break device is performed by clamping and fixing the break blade cartridge in advance by fixing and holding the break blade, and the attachment position thereof By reproducing the break blade, the break blade can be replaced quickly and easily, and the throughput in the break device can be improved as compared with the prior art.

And an extending portion 200c. The extending portion 200c has a reference surface 202 that is perpendicular to the inclined surface 201 and parallel to the one main surface 200d having a right triangle shape of the main body portion 200b.

  Similar to the inclined surface 201, the reference surface 202 has a longitudinal direction in a direction inclined by an angle θ from the y-axis direction. Thus, the inclined surface 201 and the reference surface 202 have an L-shaped cross section perpendicular to the longitudinal direction. The reference surface 202 serves as a reference in the overlapping direction of these three members when the break blade 1 is clamped and fixed between the cartridge base 11 and the pressing plate 12. Hereinafter, a direction inclined by an angle θ from the y-axis direction is referred to as a jig longitudinal direction for convenience. The reference surface 202 has cartridge base positioning pins 202a erected in the z-axis direction in the vicinity of the lower end of the jig in the longitudinal direction.

  Although the details will be described later, in the fixing jig 200, the L-shaped portion in cross-sectional view formed by the inclined surface 201 and the reference surface 202 is the mounting portion of the break blade cartridge 10, and the break blade cartridge 10 is placed along the longitudinal direction of the jig.

  In addition, a pair of cartridge clamps 203 is provided on one main surface (side surface) 200d of the main body 200b. The pair of cartridge clamps 203 are provided separately from each other in the jig longitudinal direction. The pair of cartridge clamps 203 respectively move in the plane perpendicular to the xy plane with the contact portion 203a which can be advanced and retracted in the z-axis direction and the clamp handle 203b with the rotation axis 203c as the rotation center. And a clamp mechanism 203d for advancing and retracting the contact portion 203a in the z-axis direction.

  Specifically, in the state where the break blade cartridge 10 is placed, the clamp handle 203b is rotated in the direction indicated by AR3 in FIG. Contact with the front face 12c of the As a result, a state in which the break blade cartridge 10 is fixedly held by the fixing jig 200 is realized. As will be described later, the clamping operation in the actual use phase is performed in a state where the overlapped body before being fixed with the fixing screw 13 is placed.

  On the other hand, when the clamp handle 203b is rotated in the direction indicated by AR4 in FIG. 10, the contact state of the contact portion 22a with the front surface 12c is released.

  In order to fix the break blade 1 to the break blade cartridge 10 using the fixing jig 200 having the above configuration, first, only the cartridge base 11 is mounted on the mounting portion of the fixing jig 200. (Step S1). FIG. 11 shows the state of such placement. Specifically, the cartridge base 11 has its upper surface 11c in contact with the inclined surface 201, its rear surface 11e in contact with the reference surface 202, and its longitudinal end in contact with the cartridge base positioning pin 202a. It is placed in a manner to At this time, the contact of the cartridge base 11 with the inclined surface 201 and the cartridge base positioning pin 202 a is naturally realized by the weight of the cartridge base 11.

  Subsequently, the break blade 1 is disposed on the surface 11a of the cartridge base 11 placed in this way (step S2). The break blade 1 is arranged in such a manner that the blade edge 1a faces upward. When the break blade 1 is arranged, the surface 11b of the cartridge base 11 is inclined, and the break blade positioning pin 14a provided in the cartridge base 11 is positioned in the vicinity of the lower end in the jig longitudinal direction. There is. That is, the arrangement relationship between the break blade 1, the surface 11b, and the break blade positioning pin 14a is similar to the arrangement relationship between the cartridge base 11, the inclined surface 201, and the cartridge base positioning pin 202a. Therefore, the contact of the break blade 1 with the surface 11b and the break blade positioning pin 14a is naturally realized.

  Subsequently, the pressing plate 12 is superimposed on the breaking blade 1 (step S3), but the positional relationship between the pressing plate 12 and the surface 11b and the pressing plate positioning pins 14b when the pressing plate 12 is disposed is also Again, the arrangement relationship between the cartridge base 11, the inclined surface 201, and the cartridge base positioning pin 202a is similar. Therefore, the contact with the surface 11b of the pressing plate 12 and the positioning pin 14b for the pressing plate is naturally realized.

  When the arrangement of the break blade 1 and the pressing plate 12 is completed in the manner as described above, the clamp handle 203b is subsequently rotated in the direction indicated by the arrow AR3 to perform clamping by the cartridge clamp 203 (step S4). . The overlapping body formed by sandwiching the break blade 1 between the cartridge base 11 and the pressing plate 12 is clamped and fixed between the reference surface 202 and the abutting portion 203a of the cartridge clamp 203 by the clamp. In the state of such clamping and fixing, the cartridge base 11 is brought into contact with the reference surface 202, and the break blade 1 and the holding plate 12 stacked thereon are also brought into contact successively, as a result, these cartridges A state in which the base 11, the break blade 1, and the pressing plate 12 are positioned with respect to the reference surface 202 is realized.

  Then, in a state where such a clamp is performed, screwing is performed by the fixing screw 13 from the front surface 12 c side of the pressing plate 12 so that the break blade 1 is held and fixed between the cartridge base 11 and the pressing plate 12. (Step S5). Then, when the clamping and fixing are performed, the clamp by the cartridge clamp 203 is released (step S6). Thereby, the break blade cartridge 10 in which the break blade 1 is fixedly held is obtained.

  According to the above procedure, since the break blade 1, the cartridge base 11 and the pressing plate 12 are always arranged at the same position, the fixing with the fixing screw 13 is performed. The fixed position of the break blade 1 at the time of being fixed by clamping is always the same. That is, even if the break blade 1 is replaced, the fixed position of the break blade 1 in the break blade cartridge 10 is reproduced. In addition, since the screwing with the fixing screw 13 is intended to be clamped and fixed in advance by the clamping operation, it is possible to avoid displacement of the presser plate 12 and the break blade 1 when a force is applied to the screw.

  That is, when the fixing jig according to the present embodiment is used, the attachment of the break blade to the break device is performed by clamping the break blade cartridge by fixing and holding the break blade in advance. The break blade can be fixed with good reproducibility.
