FIG. 1 is a perspective view of a dividing apparatus showing a method for dividing a sheet-like substrate in an embodiment of the present invention. In FIG. 1, reference numeral 11 denotes a first conveying belt that conveys a sheet-like substrate 13 having a dividing groove 16 via a first roller 12. Reference numeral 14 denotes a unit that moves up, down, left, and right disposed almost above the end of the first transport belt 11, and holds a suction pad 15 in the unit 14, and the suction pad 15 is used for the first transport belt. The sheet-like substrate 13 placed on the upper surface of the belt 11 is sucked and transferred to a first dividing belt 17 described later. Reference numeral 17 denotes a first dividing belt which is located almost at the end of the first conveying belt 11 and is disposed at substantially the same height as the first conveying belt 11, and this first dividing belt. 17 is stretched around the second roller 18 and the third roller 19, and travels when the third roller 19 is rotationally driven. In this case, a small-diameter roller 20 is disposed between the second and third rollers 18 and 19 so as to contact the inner surface of the first dividing belt 17, and the small-diameter roller 20 is a sheet-like substrate. This contributes to dividing 13 into strip-shaped substrates 21. Further, the width of the first dividing belt 17 is wider than the width of the sheet-like substrate 13. Reference numeral 22 denotes a second dividing belt disposed above the first dividing belt 17. The second dividing belt 22 is stretched around the fourth and fifth rollers 23 and 24. It is what. The second dividing belt 22 travels when the large-diameter roller 25 is rotationally driven.
[0018]
The large-diameter roller 25 is positioned between the fourth and fifth rollers 23 and 24 and contacts the inner surface of the second dividing belt 22 and contacts the inner surface of the first dividing belt 17. It contributes when dividing the sheet-like substrate 13 into strip-like substrates 21 located above the small-diameter roller 20. Further, the width of the second dividing belt 22 is wider than the width of the sheet-like substrate 13. A transport film 26 runs between the first and second dividing belts 17 and 22, and the transport film 26 sandwiches the sheet-like substrate 13 between the first split belt 17 and forms a sheet. After the substrate 13 is divided into strip-shaped substrates 21, the third roller 19 rotates 180 degrees, so that the strip-shaped substrate 21 sandwiched between the first dividing belt 17 and the transport film 26 is reversed. The strip-shaped substrate 21 is transported to the vicinity of the second roller 18.
[0019]
The transport film 26 is made of a polyethylene terephthalate film, and the width thereof is narrower than the width of the sheet-like substrate 13. The suction block 27 is located near the second roller 18 and at the lower end of the first dividing belt 17 and is disposed on both sides of the transport film 26.

Reference numeral 28 denotes a pair of second transport belts located on both sides of the transport film 26 and disposed at substantially the same height as the transport film 26, and is placed on the upper surface of the transport film 26. The strip-shaped substrate 21 is transferred to the second transport belt 28 as the transport film 26 moves.
[0020]
In the dividing apparatus showing the method for dividing a sheet-like substrate configured as described above, a method for dividing and arranging sheet-like substrates will be described below.
[0021]
First, the sheet-like substrate 13 is placed on the upper surface of the first conveying belt 11 and moved to the lower part of the suction pad 15.
[0022]
Next, the sheet-like substrate 13 is sucked by the suction pad 15 to move the sheet-like substrate 13 from the first conveying belt 11 to the upper surface of the first dividing belt 17.
[0023]
Next, the first dividing belt 17 is driven by the rotation of the third roller 19, and the conveying film 26 that runs between the first and second dividing belts 17, 22 and Between the small-diameter roller 20 that contacts the inner surface of the first dividing belt 17 and the large-diameter roller 25 that contacts the inner surface of the second dividing belt 22 while holding the sheet-like substrate 13 with the first dividing belt 17. When the sheet-like substrate 13 passes, the sheet-like substrate 13 is distorted and divided into strip-like substrates 21 at the division grooves.
[0024]
Next, the second dividing belt 22 is separated from the first dividing belt 17, and the strip-shaped substrate 21 is sandwiched between the upper surfaces of the first dividing belt 17 by the transport film 26, and the third roller 19. Is rotated 180 degrees, the strip-shaped substrate 21 sandwiched between the first dividing belt 17 and the transport film 26 is reversed, and the strip-shaped substrate 21 is disposed on the upper surface of the transport film 26. Further, it is held by the first dividing belt 17.
[0025]
Next, the first dividing belt 17 and the transport film 26 travel together, and the strip-shaped substrate 21 is sucked by the suction block 27 disposed in the vicinity of the lower end of the second roller 18, and is used for transport. The suction block 27 is moved to a predetermined position on the upper surface of the film 26 at the same speed as the transport film 26. During this movement, the first dividing belt 17 is separated from the transport film 26.
[0026]
Finally, when the transport film 26 travels, the strip-shaped substrate 21 positioned on the upper surface of the transport film 26 has a pair of second plates disposed on both sides of the transport film 26 at substantially the same height as the transport film 26. Thus, the divided strip-shaped substrate 21 can be aligned in a state where it can be easily automated.
[0027]

Since the method includes the step of transferring to the second transport belt 28, the divided strip-shaped substrate 21 is placed on the upper surface of the transport film 26, thereby dividing the strip-shaped substrate. 21 can be aligned in a state where it can be easily automated.
[0028]
In the embodiment of the present invention, since the width of the transport film 26 is narrower than the width of the sheet-like substrate 13, the strip-shaped substrate 21 placed on the upper surface of the transport film 26 is replaced with the second substrate 21. When transferring to the conveyance belt 28, this transfer can be performed smoothly.
[0029]
In one embodiment of the present invention, the first dividing belt 17 and the second dividing belt 22 are wider than the sheet-like substrate 13, so the first dividing belt 17. When the sheet-like substrate 13 is divided between the second dividing belt 22 and the second dividing belt 22, the sheet-like substrate 13 is hardly broken in the direction perpendicular to the dividing direction.
[0030]
Furthermore, in one embodiment of the present invention, after the first dividing belt 17 is separated from the strip-shaped substrate 21 placed on the upper surface of the transport film 26, the strip-shaped substrate 21 is moved to the second transport belt 28. In the process of transferring to the strip substrate 21, suction blocks 27 are provided on both sides of the transport film 26, and at least the first dividing belt 17 is separated from the strip substrate 21 by the suction blocks 27. Therefore, the strip-shaped substrate 21 can be separated from the first dividing belt 17 in a stable state.
[0031]
Furthermore, in one embodiment of the present invention, since the transport film 26 is made of a polyethylene terephthalate film, the transport film 26 having a high tensile strength and toughness can be obtained and damaged. What is difficult is obtained.
[0032]
