Embodiment 1
[0023] figure 2 The glass plate W1 to be processed is displayed, and its size is 370 mm in width x 310 mm in height. The alignment mark M is located on the inside of each 10mm from the upper end and both sides in the figure. Then combine image 3 The flow chart will be explained: as the scribe line in the Y direction, move from the alignment mark on the left to x=20mm at the inner side of 10mm, and scribe 12 lines at 30mm intervals, and as the scribe line in the X direction, from y =20mm, scribe 10 lines at intervals of 30mm, and operate according to the above situation.
[0024] Initially, in step S1, various scribing data are input. The scribe line data is input: the size of the glass plate W1, the position of the alignment mark M, the position of the first scribe line, the scribe line pitch (x and y directions), and the individual undercut amount and undercut for each scribe head 7 pressure.
[0025] In step S2, the following equations are calculated for the coordinat...
Embodiment 2
[0072] Figure 5 The glass plate W2 to be processed is displayed, and its size is 360 mm in width and 310 mm in height. The alignment mark M is located on the inside of each 10mm from the upper end and both sides in the figure. Here, as the scribe lines in the Y direction, eight lines are scribed at intervals of 45 mm from the alignment mark on the left side, and the above-mentioned situation of the present embodiment will now be described.
[0073] The starting position Xn of the scribing area in the X direction for which each of the five scribing heads 7 is in charge is calculated as follows.
[0074] Xn=(horizontal (X direction) size / 5)×(n-1)
[0075] Since the glass width in the X direction is 360mm, it becomes
[0076] 0≤x1<72
[0077] 72≤x2<144
[0078] 144≤x3<216
[0079] 216≤x4<288
[0080] 288≤x5<360
[0081] pass:
[0082] Scribing head①: x=10, x=55
[0083] Scribing head ②: x=100
[0084] Scribing head ③: x=145, x=190
[0085] Scribing head④: x=235, x=28...
Embodiment 3
[0097] Image 6 It is the glass plate W3 which shows the processing object, and its size is 370 mm in width x 310 mm in height. The alignment mark M is located on the inside of each 10mm from the upper end and both sides in the figure. Here, the case where six lines are scribed at intervals of 40 mm, 60 mm, 80 mm, 100 mm, and 50 mm from the left alignment mark inward by 10 mm as the scribe line in the Y direction will be described.
[0098] The scribing area Xn in the X direction that each of the 5 scribing heads 7 is responsible for is figure 2 The same situation becomes:
[0099] 0≤X1<74
[0100] 74≤X2<148
[0101] 148≤X3<222
[0102] 222≤X4<296
[0103] ≤X5<370
[0104] pass:
[0105] Scribing head①: x=20, x=60
[0106] Scribing head ②: x=120
[0107] Scribing head ③: x=200
[0108] Scribing head ④: None
[0109] Scribe head (5): x=300, each of the lines of x=350 becomes the object of scribing.
[0110] In the first scribing, the scribing heads ① to ③ are scribi...
