Description

[0001] SCRIBING APPARATUS OF THE SUBSTRATE [0002]
Disclosure of the Invention The present invention relates to a method of manufacturing a glass substrate or a film substrate on which a glass substrate or film such as a large liquid crystal panel is adhered and a plurality of cutting lines for small- The present invention relates to a scribing apparatus for a substrate on which a substrate is formed.
Productivity can be improved by simultaneously obtaining a plurality of substrates of a product size from a glass substrate of a large liquid crystal panel at one time.
In order to achieve the above object, a large-size glass substrate is mounted on a reciprocating table, and then a plurality of cutters and needles arranged at a predetermined interval on the right side of the traveling path of the table, a plurality of parallel cutting lines for small cutting are formed on the surface (upper surface) of the glass substrate at one time by the descent of a scribe jig such as a needle, a laser line or the like. The small cutting lines are formed only in the X-axis direction or in the X-axis direction and the Y-axis direction.
Each of the scribing jigs in parallel can be adjusted in intervals by numerical control so as to match the dimensions of the product size (see, for example, Patent Document 1).
In addition to the above, there is one that enables accurate scribing by a camera (see, for example, Patent Documents 2 and 3).
Japanese Patent Application Laid-Open No. 11-343133 Japanese Patent Application Laid-Open No. 2009-73714 Japanese Utility Model Utility Model Publication No. 6-415
According to the cutting method of the plate glass of Patent Document 1, it is possible to form a cutting line capable of simultaneously obtaining a plurality of substrates of a product size from a large glass substrate at one time, thereby improving the productivity.
However, in the cutting method of Patent Document 1, test cutting (forming a cutting line) is performed on a mother substrate in an initial stage, and it is confirmed whether or not each formed cutting line is in a scribing position, Adjust the position of the cutter when it is not in the scribe position. The adjustment of the position of the cutter is performed by sequentially supplying the glass substrate and forming a cut line.
However, when the test cutting is performed, a large and expensive mother substrate is used, which causes waste and unnecessary expenditure.
Further, since the test cutting is performed every time the cutting line is changed, there is also a problem that the operation rate of the machine remarkably decreases due to the confirmation of the scribe position in addition to the considerable expenditure of the cost.
Further, according to the apparatus for cutting a glass substrate of Patent Document 2, since the scribe fixture is positioned so as to correct the displacement of the scribe processing position by the camera every inspection of the substrate or each inspection, the tact operation is significantly .
In the method of cutting the glass substrates of Patent Documents 1, 2 and 3, scribing of a plurality of product sizes at one time can be performed by moving the cutter and the table.
However, while it is possible to position the parallel cutter in the Y-axis direction (lateral direction intersecting with the running direction of the table), it is not possible to adjust the X-axis direction of each cutter (running direction of the table). That is, there is no position adjusting function in the X-axis direction.
Then, when the position of the parallel cutter is displaced (relative to the X axis), as shown in Fig. 13, the position of the table T of the scribed product T in the table direction is not parallel to the X axis, Occurs. This creates defective products. That is, the electrode surface (electrode surface) of the product T is inconsistent.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a scribing apparatus for a substrate which solves the above problems.
In order to solve the above problems, the present invention provides a vehicle comprising a traveling body provided for reciprocating travel, a table provided on the traveling body for supporting a large-sized substrate pivotally mounted on the traveling body by the pivoting means, A plurality of sliders provided on the guide rails transverse to the upper side of the traveling path so as to slide in the left and right directions respectively by means of the lateral direction moving means and a scribe fixture provided on the respective sliders so as to ascend and descend by the elevating means, And a camera mounted to read each of the scribe marks and the alignment marks of the substrate, wherein the camera reads the alignment mark of the substrate and, based on the amount of machining difference (deviation amount) When turning the table And a scribing process amount according to a scribing mark of the substrate by the camera and a short test cutting line read by the cutter is calculated and the slider is moved to the scribe line coordinates by the lateral moving means, A correction value is calculated from the distance between the scribe center line and the center of the scribe reference at the time of completing the scribe and the correction value is added to and subtracted from the moving distance of the scribe fixture for the next scribe.
A table provided so as to support a large substrate which is swiveled and mounted on a plane by the pivoting means on the traveling body, and a table which is provided on a horizontal bar crossing directly above the traveling path of the table A slider having a plurality of position adjusting means provided so as to slide in the left and right direction by the lateral moving means, a moving base provided on the base of each slider so as to slide in the running direction of the table by the longitudinal moving means, A scribe fixture provided on each of the movable belts so as to ascend and descend by the elevating means, and a camera mounted to read the alignment mark and each pattern mark of the substrate on each of the movable belts. Accordingly, By and pivot the table, according to the reading of each pattern mark by each camera is in the normal scribe position to move the moving base by the moving means employing a configuration that is characterized in that to move the scribing tool.
As described above, according to the scribing apparatus for a substrate of the present invention, the machining difference amounts to the left and right sides of the glass substrate due to the reading (recognition) of the alignment marks by the camera are corrected by turning the table by the turning means, A short test cutting line and a scribe mark formed on a substrate by lowering the cutter and running the table slightly are respectively read and recognized by the camera and the amount of difference between the test cutting line and the scribe mark according to the recognition is detected by the lateral moving means The test slice using the mother substrate is unnecessary because the slider is slid in the left or right direction and corrected.
Therefore, unnecessary expenditure can be eliminated because a large and expensive mother substrate is used, and a problem that a considerable operating rate of the machine is reduced due to the test cutting and confirmation of the scribing position thereafter can be eliminated.
In particular, since the correction value is calculated from the distance between the scribe center line and the center of the scribe reference at the completion of scribing and the correction value is added to or subtracted from the moving distance of the scribe fixture for the next scribe, the operation rate of the tact operation sequentially scribed is greatly The scribing accuracy can be stabilized and the yield can be improved.
In addition, a scribe fixture and a camera are installed on the movable table, and the moving table is moved by the longitudinal moving means in the forward and backward directions of the table, and the pattern mark is read and recognized by the camera.
