- the scribe line forming means 207 is formed with a V-shaped blade 207b projecting in the outer peripheral direction of the scribing line forming means 207 (see FIG. 4). At the tip of the blade 207b, a blade edge line 207a is formed (see FIG. 4).
- the first rotation shaft 204 is provided on the lower surface of the holder 203.
- the axis of the first rotating shaft 204 is located at a position away from the axis Q of the second rotating shaft 202 by an offset distance S in the direction opposite to the moving direction of the scribe line forming mechanism 201 (the direction of the arrow shown in FIG. 3).
- Heart R is located.
- the first rotating shaft 204 is rotatably supported by a first bearing 208. Further, the first rotation shaft 204 is provided so that the axis R of the first rotation shaft 204 intersects with the axis of the pin 206.
- the scribe line forming means 207 is arranged so that a contact point (hereinafter referred to as a processing contact point) between the scribe line forming means 207 and the substrate G is located on an extension of the axis R of the first moving shaft 204. Have been killed. Therefore, the scribe line forming mechanism 201 is provided in the scribe head such that the axis of the second rotation shaft 204 is substantially perpendicular to the surface of the substrate G.
- Scribe line forming means Position relation of second rotation axis
- FIG. 4 shows the positional relationship between the scribe line forming means 207 and the second rotating shaft 202 when the scribe head 200 moves.
- the substrate G is, for example, a glass substrate.
- the scribe line forming mechanism 201 is attached to the scribe head 200, and a small deviation width ⁇ is formed between the ridge line 207a of the scribe line forming means 207 and the axis Q of the second rotation shaft 202. Then, the scribe line forming means 207 starts forming scribe lines on the substrate G (see FIG. 4A).
- a processing reaction force when scribing the substrate G acts on the scribe line forming mechanism 201 via the pin 206. Since the scribe line forming means 207 is provided such that the axis R of the first rotary shaft 204 is located almost directly above the processing contact point of the scribe line forming means 207, the scribe line forming means 207 The scribe line 207a of the scribe line forming means 207 rotates in a direction in which the scribe line forming means 207 is rotated around the axis R of the rotating shaft 204 and the processing reaction force received at the processing contact point is balanced. (See Fig. 4 (b)).
- the direction of the line of action on which the scribe head 200 pulls the scribe line forming means 207 and the direction of the edge line 207a of the scribe line forming means 207 match. Since the turning radius is very small (the axis R of the first rotating shaft 204 and the machining contact point are almost coincident), the balance against the machining reaction force can be achieved by moving the scribe head 200 only slightly. The edge line 207a of the cutting edge of the scribe line forming means 207 rotates in the obtained direction.
- the cutting edge ridge line 207a of the scribe line forming means 207 is inclined by a small angle with respect to the movement locus (line V) of the axis Q of the second rotation shaft 202.
- the scribe line forming mechanism 201 rotates counterclockwise around the axis Q of the second rotation shaft 202, and the ridge line 207a of the scribe line forming means 207 and the axis Q Trajectory V of the movement locus becomes smaller. (See Fig. 4 (c)).
- the processing contact point moves on the movement locus of the axis Q of the second rotation shaft 202 (see FIG. 4D).
- the scribe line forming means 207 continues to form a scribe line while maintaining a state in which the cutting edge ridge line 207a of the scribe line forming means 207 and the movement trajectory of the axis Q of the second rotating shaft 202 overlap. 4 (d)).
- the scribe line forming means 207 rotates around the axis R of the first rotating shaft 204, and the blade edge 207a of the scribe line forming means 207 rotates to a new balance position. That is, the scribe line forming mechanism 201 rotates so that the cutting edge 207a of the scribe line forming means 207 is directed on a straight line connecting the axis Q and the processing contact point of the scribe line forming means 207.
- the axis R of the first rotation shaft 204 substantially coincides with the processing contact point, that is, the rotation radius is very small. Accordingly, the scribe line forming means 207 moves to a new balance position of the processing reaction force received by the scribe line forming means 207 by a slight movement of the scribe head 200.
- the scribe line forming means 207 moves around the axis Q of the second rotation shaft 202 while rotating. Immediately after the movement, the difference between the processing reaction forces received by the left and right blade surfaces of the scribe line forming means 207 is minimized, and the scribe line forming means 207 is positioned at the position where the balance of the processing reaction forces received by the scribe line forming means 207 is most stable. Moving. For this reason, the scribe line forming means 207 rotates around the first rotation axis 204, and the direction of the straight line connecting the processing contact point and the axis Q of the second rotation axis 202 is determined by the scribe line forming means 207.
- the scribe line forming mechanism 201 operates so that the rotational movement direction of the edge line 207a of the cutting edge coincides with that of the ridge line 207a. Therefore, the scribe situation is the same as situation 1.
- the scribe line forming mechanism 201 rotates around the axis Q of the second rotating shaft 202 while the ridge line 207 a of the scribe line forming means 207 is positioned at the axis Q. Approach the trajectory.
- the scribe line forming mechanism, the scribe head, and the scribe device of the present invention even when the displacement width ⁇ is zero and scribing is performed using the scribe line forming mechanism, the scribe line is changed according to the change in the processing reaction force. At least one of the scribe line forming mechanism 201 and the scribe line forming means 207 rotates in a direction in which the direction of the edge line 207a of the scribe line forming means 207 is immediately stabilized. Therefore, even when a large change is received, the caster effect at the time of the scribe operation can be obtained as in the case where the shift width ⁇ is zero. As a result, it is not necessary to pay much attention to making the processing accuracy and the assembly accuracy strict and setting the deviation width ⁇ to zero. This is advantageous in that the manufacturing cost of the scribe line forming mechanism can be reduced.
- the rotational movement direction of the cutting edge 207a of the scribe line forming means 207 is the same as the running direction of the scribe head. Since they match, a stable scribe operation with good straightness can be obtained.
- the scribe line forming means 207 starts at a position shifted by the shift width ⁇ to the left (upward in FIG. 4) in the traveling direction of the axis Q of the second rotation shaft 202. As described above, the scribe line is started, The same effect can be obtained when scribing is started with a position where 207 is shifted to the right (downward in FIG. 4) in the traveling direction of the axis Q of the second rotating shaft 202 by ⁇ as a starting point. Can be.
- a scribe line with good linear accuracy can be formed on the substrate G.
- the deviation width ⁇ between the blade edge 207a of the scribe line forming means 207 and the axis Q of the second rotating shaft 202 is reduced. Even if the scribe head 200 starts moving, the blade edge 207a of the scribe line forming means 207 rotates in a direction overlapping with the line of action on which the tensile force of the scribe head acts. Therefore, the deviation angle ⁇ (see FIG. 21 (b)) of the cutting edge ridge line 207a of the scribe line forming means 207 with respect to the movement trajectory line of the axis Q of the second rotation shaft 202 is quickly brought close to zero.
- the scribe line forming means 207 rolls, and the edge line 207a of the cutting edge of the scribe line forming means 207 approaches the movement trajectory line of the axis Q. In this way, the scribe line forming means 207 reaches a position overlapping the movement locus of the axis Q of the second rotating shaft 202 due to the caster effect acting as the scribe head 200 moves, and the stable scribe operation is performed. Is executed.
