And a collet 16 formed on one side of the collet beam 14 and holding the substrate 2. Further, the chuck beam 14 is moved toward the scribing unit 30 in the front-rear direction, whereby the substrate 2 held by the chuck 16 is scored while passing through the lower portion of the scribing head 34.

In the present embodiment, the second transport unit 20 is divided into a second transport unit 22 (hereinafter, also referred to as a post-mortem transport unit) on the upstream side in the transport direction of the substrate, and a second downstream side on the downstream side. The transport unit 24 (hereinafter also referred to as a pick-up transport unit).

The post-scoring transfer unit 22 mounts a portion of the substrate that has been scribed by the scribing unit 30 from the first transport unit 20, and the pick-up transport unit 24 picks up the substrate by, for example, picking up a robot or the like. The portion of the substrate 2a transferred from the post-scoping transfer portion 22 is temporarily placed.

In the present embodiment, the post-transporting unit 22 and the pick-up and transport unit 24 are configured to be integrated with each other as the second transport unit 20 in the present embodiment. The dancer roller unit 23 between the transport portion 22 and the pick-up transport portion 24 is scored.

The dancer roller unit 23 is provided between the post-scoping transport unit 22 and the pick-up transport unit 24, and has at least a pair of first rollers 23a and second rollers 23b. In FIG. 3, only the pair of first roller 23a and second roller 23b are shown. However, the present invention is not limited thereto, and may be applied to a dancer roller unit including two or more pairs of rollers. Further, in Fig. 3, the first roller 23a is located outside the track of the belt portion 28 on the outer side of the second transport portion 20, and the second roller 23b is located at the second. The inner side of the transport unit 20 is the inner side of the rail of the belt portion 28. However, the present invention is not limited thereto, and the first roller 23a may be located inside the rail of the belt portion 28, and the second roller 23b may be located on the rail of the belt portion 28. The composition of the outside.

The first roller 23a and the second roller 23b of the dancer roller unit 23 are formed to be movable in a second direction (in the +Z direction or the -Z direction in FIG. 3) that intersects the substrate transport direction, that is, the first direction. Further, the first roller 23a and the second roller 23b are formed to move in opposite directions when moving. For example, when the first roller 23a moves in the -Z direction, the second roller 23b moves in the +Z direction, and when the first roller 23a moves in the +Z direction, the second roller 23b moves in the -Z direction. The first roller 23a and the second roller 23b are coupled to each other in conjunction with each other. The combination structure will be described in detail later.

In this manner, between the post-scratching transport unit 22 and the pick-up transport unit 24, the dancer roller unit 23 including the first roller 23a and the second roller 23b that are movable in opposite directions is formed, whereby the second The movement of the belt portion 28 of the scribing portion 20 can be controlled to be independent in the post-scoping transport portion 22 and the pick-up transport portion 24. That is, it can be controlled in such a manner that the belt portion 28 of the transport portion 22 is rotated after scribing, but the belt portion 28 of the pick-up transport portion 24 is stopped, or conversely, the belt portion of the transport portion 24 is picked up. The rotation is performed 28, but the belt portion 28 of the conveying portion 22 is stopped after scoring. In this way, the post-scoping transfer unit 22 and the pick-up transfer unit 24 are integrally formed without being transferred by transfer (constituted by one belt portion 28), but the actuation state can be mutually Controlled for different ways.

Therefore, the substrate which can be placed on the post-scratching transport unit 22 can be transported along the belt portion 28 so as not to be transferred to the second pick-up transport unit 24. Therefore, there is an effect that it is possible to prevent the substrate from being cut from the downstream side as in the conventional substrate breaking device. When the portion is transported to the pick-up and transport portion, the transfer of the transport portion causes problems such as falling of the end material or glass debris, and also prevents the problem of damage to the surface of the substrate caused by the transfer of the transport portion. This will be described more specifically with reference to FIGS. 4(a) to 4(d).

4(a) to 4(d) are diagrams schematically showing a substrate transfer process of the substrate cutting device according to the embodiment of the present invention. Fig. 4(a) is a diagram showing the stage of starting the dicing of the substrate. Referring to Fig. 4(a), the substrate 2 to be scribed is held by the chuck 16. Further, the substrate 2a which has been scored is placed on the pick-up transfer portion 24 to be picked up.

On the other hand, the dancer roller unit 23 of the present embodiment is provided with a first brake 50a formed on the side of the post-scratching transport unit 22 with respect to the first roller 23a, and a first roller 50a as a reference. The second brake 50b on the side of the conveying unit 24 is picked up. The first brake 50a and the second brake 50b are used to reliably stop the rotation of the belt portion 28 of the second transport unit 20, and in FIG. 4(a), the second brake 50b is lowered to cause the pick-up transport unit 24 to be lowered. The rotation of the belt portion 28 is surely stopped.

(b) of FIG. 4 is a view showing a stage in which the substrate 2 is scribed, and the substrate 2a on the pick-up transfer unit 24 is picked up and unloaded in a lower stage such as a transport unit (not shown). formula.

4(a) and 4(b), the chuck beam 14 is moved in the substrate transport direction (in the +Y direction in FIG. 4(b)), whereby the substrate 2 held by the chuck 16 is also passed through the scribing head. 34 below. At the same time, the first roller 23a moves in the -Z direction, and the second roller 23b moves in the +Z direction opposite to the moving direction of the first roller 23a.

At this time, the operation of the belt portion drive motor 40 is turned on, and since the belt portion 28 is surely wound around the third roller 21a, the first roller 23a and the second roller 23b are moved. At the time of the movement, only the belt portion 28 on the side of the rear conveying portion 22 is actuated, and the belt portion 28 on the side where the conveying portion 24 is picked up is not actuated. As shown in FIG. 4(b), the second brake 50b may be lowered to stop the belt portion 28 of the pick-up conveyor portion 24 more reliably.

Further, in the present embodiment, the distances at which the first roller 23a and the second roller 23b move are formed to be the same as each other. In other words, when the first roller 23a is moved by the distance L in the -Z direction, the second roller 23b is also adjusted so as to move the distance L in the +Z direction. Thereby, while the distance moved by the first roller 23a in the -Z direction and the distance moved by the second roller 23b in the +Z direction are offset, only the belt portion 28 of the rear conveying portion 22 is scored by the first roller 23a or The degree of the movement of the second roller 23b is rotated clockwise. Thereby, the substrate 2 held by the chuck 16 can continue to move on the belt portion 28 of the post-scratching transport portion 22 after passing through the lower portion of the scribing head 34 to reach the post-scouring transport portion 22.

After that, the chuck beam 16 and the chuck 14 are retracted in the opposite direction to the transport direction of the substrate (in the -Y direction in FIG. 4(b)), and at the same time, the first roller 23a moves again in the +Z direction, and The second roller 23b is again moved in the -Z direction, whereby the belt portion 28 of the transport portion 22 after the scribing is rotated counterclockwise again to the extent that the first roller 23a or the second roller 23b is moved.

At this time, when the belt drive motor 40 is actuated, the third roller 21a is rotated in the clockwise direction, the first roller 23a is moved in the +Z direction, and the second roller 23b is moved in the -Z direction. The belt portion 28 of the transport portion 24 is rotated clockwise, and the belt portion 28 of the transport portion 22 after the scribing is maintained in a stopped state. Thereby, only the end material remaining on the belt portion 28 of the pick-up conveying portion 24 can be transferred to the crusher in a state where the substrate 2 on the belt portion 28 of the post-scratching conveying portion 22 is stopped.

Further, in this case, since the second brake 50b is raised and the first brake 50a is lowered, the rotation of the belt portion 28 of the pick-up conveyor portion 24 is not restricted, and only the post-tracking is transmitted. The movement of the belt portion 28 of the portion 22 is more reliably stopped.

4(d) is a view showing a stage in which a new substrate is loaded onto the first transport unit 10, and the substrate placed on the belt portion 28 of the post-scratching transport unit 22 is transported to the pick-up transport unit 24. . Referring to FIG. 4(d), the first substrate 10 is placed on the tape portion 18 of the first transfer unit 10 in the first transfer unit 10, and is held by the chuck beam 14 at the initial position. Chuck 16.

When the first roller 23a is continuously moved in the +Z direction and the contact with the belt portion 28 is released, the belt portion 28 is returned to the non-bending flat state, and the substrate is placed and transported. The belt transfer portion between the belt portion 28 of the transport portion 22 and the belt portion 28 of the pick-up transport portion 24 does not have a transport transfer portion. Then, the first brake 50a is raised to release the contact with the belt portion 28.
