Description

  The present invention relates to a setting jig for a substrate cutting unit used for cutting a brittle material substrate such as a glass substrate, and in particular, a wheel having a scribe wheel and a cutting wheel and a variable distance between the two wheels. It relates to a distance setting jig.

  In general, when a glass substrate or the like which is a brittle material substrate is cut, a “scribe process” is performed in which a scribe line is formed on the glass substrate with a scribing device, and a crack is formed along the streak line. Thereafter, a “breaking step” is performed in which a shearing force is applied to the glass substrate along the formed scribe line to push and divide the glass substrate.

  As described above, the glass substrate is broken (divided) through a plurality of processes including a scribing process and a breaking process. In addition, the breaking process has many parts that rely on human hands, which is a bottleneck for labor saving. It was.

  Therefore, Patent Document 1 discloses a cutting device in which a first rotary cutter and a second rotary cutter are arranged in series. The first rotary cutter is for forming a V-shaped groove on the glass substrate by plastic deformation, and the second rotary cutter further has a groove reaching the back surface of the glass substrate by further progressing the plastic deformation. It is for forming.

  The cutting device disclosed in Patent Document 1 is intended to cleave the glass substrate without going through the above-described breaking process, and the second rotary cutter forms the V-shaped groove formed by the first rotary cutter. The glass substrate is to be cleaved by further progressing to the back surface of the glass substrate.

JP 2007-39302 A

  As televisions and the like are becoming larger as in recent years, glass substrates used for television displays are becoming harder and mother glasses for glass substrates are becoming larger.

  However, when the cutting device of Patent Document 1 is applied to such a large glass substrate (particularly a hard glass substrate), it is difficult to divide the glass substrate in one step. Has been raised as a track record. This is because, in the cutting apparatus of Patent Document 1, the load that can be applied to the glass substrate by the first rotary cutter must be small enough not to generate horizontal cracks or microcracks, and the upper limit is naturally determined.

  Therefore, even if the second rotary cutter further plastically deforms the V-shaped groove formed by the first rotary cutter, the V-shaped groove does not necessarily extend to the back surface of the glass substrate due to insufficient load of the second rotary cutter. May not.

  In this regard, Patent Document 1 also discloses that plastic deformation is sequentially advanced using a further rotary cutter in addition to the first rotary cutter and the second rotary cutter. However, in order to run many rotary cutters, a complicated mechanism for running many cutters is required, and time for running many cutters is also required, which increases the time required for the process. .

  In order to solve such problems of Patent Document 1, the present inventor has already developed a substrate cutting unit 30 having a scribe wheel and a cutting wheel as shown in FIG.

  This substrate cutting unit forms a scribe line on a brittle material substrate with a highly penetrating scribe wheel (marking wheel) to infiltrate the crack, and the cutting wheel travels on the formed scribe line to eliminate the crack. Further, the brittle material substrate is divided by permeation.

  With such a substrate cutting unit developed by the present inventors, it is possible to cut the glass substrate in a single process. Nonetheless, in order to reliably cut the glass substrate in one step, it may be necessary to review and optimize the shape and dimensions of the substrate cutting unit (for example, the distance between the scribe wheel and the cutting wheel). . Through this review and optimization work, for example, if an optimum distance between the scribe wheel and the dividing wheel can be found, the glass substrate can be more reliably divided.

  The present invention has been made paying attention to such a problem, and provides a setting jig capable of obtaining an optimum distance between the scribe wheel and the dividing wheel. By using this setting jig, the optimum distance between the scribe wheel and the cutting wheel is found.

  In order to solve this problem, the setting jig of the present invention is used in a substrate cutting apparatus that forms a scribe line on a substrate surface and divides the substrate, and the scribe line is formed on the substrate surface by running on the substrate. A scribing wheel for forming the scribing wheel, a scribing holder for holding the scribing wheel, a cutting wheel for cutting the substrate along the scribing line by pressing the scribing line, and the cutting wheel. A setting jig comprising: a split holder that is held behind the scribe holder along a traveling direction of a wheel; and a holder joint that holds the scribe holder and the split holder, wherein the holder joint is the split holder By changing the position to hold the scribe holder and the dividing And it has a holding position changing means for changing the distance between the holder.

  Here, the holding position changing means may change the holding position of the dividing holder steplessly.

  The holding position changing means may have a linear guide and change the holding position of the dividing holder along the guide.

  Here, the holder joint may include connection means for connecting to the substrate cutting apparatus.

  Further, the connection means may be provided above the scribe holder.

  Furthermore, the said dividing wheel is a disk-shaped member, Comprising: The supporting member which passes along the said disk-shaped axial center may be hold | maintained so that it can rotate around this axial center.

  In addition, the substrate may be a brittle material substrate.

The setting jig of the present invention as described above is characterized in that the distance between the scribe wheel and the dividing wheel can be adjusted by changing the position of the dividing holder attaching means.
Because of this feature, the setting jig of the present invention is between the scribing wheel and the cutting wheel that can reliably cut the brittle material substrate in one step regardless of the working environment and the type of the brittle material substrate. Can get the distance.

The necessity of adjusting the distance between the scribe wheel and the dividing wheel will be described with reference to FIG.
FIG. 9 is a graph showing the relationship between the passage of time after passing the cutting edge of the scribe wheel and the amount of vertical cracks relative to the glass thickness at one point on the glass substrate.

  In FIG. 9, the graph shown by (a) has shown the result obtained by the normal wheel used conventionally, The graph shown by (b) is the high penetration type by embodiment of this invention. The result obtained by the scribe wheel is shown. The glass substrate has a thickness of 0.7 mm, a scribe load of 11 N, and a scribe speed (travel speed of the scribe wheel) of 100 mm / s.

  Referring to the graph (a) of FIG. 9 by the normal wheel, the amount (depth) of the vertical crack does not change from immediately after the cutting edge of the scribe wheel passes until 1 second later. However, referring to the graph (b) of FIG. 9 using a highly penetrating scribe wheel, the extension of the vertical crack was confirmed immediately after passing through the cutting edge of the scribe wheel, and after about 0.02 seconds, the thickness of the glass substrate was approximately 60%. % Has been reached.

  According to the high penetration type scribe wheel, the extension speed is high until the vertical crack reaches about 60% with respect to the thickness of the glass substrate, and then it rapidly decelerates. From 0.1 second to 1 second, the vertical crack extension rate is almost constant.

  With respect to the cracks that are thus extended by the high penetration type scribe wheel, a pressing force (hereinafter referred to as a dividing pressing force) from the scribe line to the crack progressing direction at a timing when the vertical crack amount is about 60% to 70%. A), it is possible to avoid a rapid deceleration of the crack extension speed. As a result of experiments and research by the present inventors, the amount of vertical cracks reaches 100% and the glass substrate is divided.

  Since the dividing wheel used for the setting jig of the present invention is provided for applying this dividing pressing force to the scribe line, the cracking wheel is extended when a crack extends through a point where the cutting edge of the scribe wheel is located. Must pass through the same point at the optimal or appropriate timing on the way of the vertical crack amount from approximately 60% to 70%.

  However, the time for the vertical crack amount to be approximately 60% to 70% differs depending on the working conditions such as the pressing force of the scribe wheel and the scribe speed, the material of the glass substrate, and the like. Therefore, the distance between the scribe wheel and the divided wheel must be adjusted so that the divided wheel travels on the scribe line at an optimal or appropriate timing in the middle of the vertical crack amount from 60% to 70%.

  When actually using the setting jig of the present invention, it is possible to divide the brittle material substrate in one step by trying several times to divide the brittle material substrate while changing the position of the dividing holder mounting means. Find the distance between the scribe wheel and the split wheel and make that distance the optimum distance between the scribe wheel and the split wheel.

  If the optimum distance can be found, it is sufficient to continue the cutting work of the brittle material substrate using this setting jig as it is, but this setting jig is only used as a gauge for finding the optimum distance, and for the actual cutting work, A substrate cutting unit having a conventional configuration manufactured so as to have the optimum distance may be manufactured and used.

  ADVANTAGE OF THE INVENTION According to this invention, while being able to obtain the optimal distance between a scribe wheel and a cutting wheel, a brittle material board | substrate, such as a glass substrate, can be reliably cut | disconnected by one process.

  After the end of step S3, it is determined whether or not the glass substrate has been divided (step S4).

  If it is determined in step S3 that the glass substrate is not divided and the glass substrate is not divided in step S4, the cutting holder attaching means 7 is changed according to the state of the crack formed in the glass substrate. The distance between the cutting holder mounting means 7 and the scribe holder mounting means 4 is adjusted by sliding along the guide groove 18 in a direction approaching the scribe holder mounting means 4 or away from the scribe holder mounting means 4. (Step S5).

After adjusting the distance between the scribe holder attaching means 4 and the dividing holder attaching means 7 in step S5 to a new distance, the process returns to step S3, and until it is determined in step S4 that the glass substrate has been divided, step S5 and Step S3 is repeated.
When it is determined in step S4 that the glass substrate has been divided, as shown in FIG. 4, the scale la carved on the holder joint 2 is read, and the gap between the divided holder attaching means 7 and the scribe holder attaching means 4 is read. An optimum distance Lo (= la + lb) can be obtained. This optimum distance is determined as the optimum value Lo between the foils (step S6).

  A substrate cutting unit 30 shown in FIG. 1 is prepared by fixing the scribing holder mounting means 4 and the cutting holder mounting means 7 at the determined optimum value Lo between the foils, and is attached to the scribing device, and the glass substrate cutting operation is continued. (Step S7).

  Alternatively, in step S6, the glass substrate cutting operation is continued using the setting jig 1 in which the scribe holder mounting means 4 and the cutting holder mounting means 7 are adjusted so that the optimum value Lo between the foils is obtained (step S8). ).

  In a continuous cutting operation, when the type or manufacturing lot of the glass substrate to be divided changes, when the substrate cutting unit 30 shown in FIG. 1 is prepared and undergoes step S7, the process returns to step S1 and is attached. The existing substrate cutting unit 30 is replaced with the setting jig 1, and the operations up to step S6 are repeated.

  On the other hand, when step S8 is performed using the setting jig 1 as it is, the distance between the scribe holder attaching means 4 and the dividing holder attaching means 7 is adjusted, the process returns to step S2, and the operations up to step S6 are repeated.

  Which of step S7 and step S8 is to be performed is selected according to actual operational conditions.

  It should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
