Has a length H equal to or shorter than the length of the cutting blade 34. The XY coordinates of the connecting portion 70 of each unit board are set and stored in advance in a predetermined storage area of the control device. As the coordinates of the connecting portion 70, the coordinates of the center point of the connecting portion are used. That is, the coordinates (X ₁ , X ₁ in the XY coordinate system with respect to the reference point of the unit substrate A ₁
Y _1), the coordinates (X ₂ with respect to the reference point of the unit substrate A _2, Y ₁₎ is set and stored in a predetermined storage area of the advance in the control device, and so the coordinate position is set and stored in the connecting portion of each unit substrate Has been done.

Next, the operation of this embodiment will be described with reference to FIG. 6 which is an operation flowchart of the control device. First, in S1, one substrate 12 is supplied from the left rack 22 to the left fixed conveyor 26 (see FIG. 1). Next, the belts 30A and 30B of the fixed conveyor are rotated to supply the substrate 12 to the movable conveyor 18 as indicated by an arrow 104 (S2).

Next, the movable conveyor 18 is moved in the XY directions from the start position to the initial position indicated by the arrow 66 as shown by the arrow 106 (S3). At this time, as described above, the movable conveyor 18 is moved so that the lower right corner 56 of the substrate coincides with the reference point of the XY coordinate system.

Next, in S4, the movable conveyor 18 is moved and positioned so that the dividing blade 34 is aligned with the position of the connecting portion 70 of the unit substrate A ₁ . The coordinates (X ₁ , Y ₁ ) in the XY coordinate system of the connecting portion 70 of the substrate A ₁ and the coordinate position of the division center 35 of the dividing blade 34 are set and stored in a predetermined storage area in advance,
The control device calculates the difference value between the coordinate position of the dividing blade 34 and the coordinate position of the connecting portion 70, and feedback-controls the position of the movable conveyor 18 so that the difference between the two becomes zero.

[0023] Then, the positioning of the movable conveyor 18 is completed, the upper blade 34A is lowered relative to the lower blade 34B, by cutting the coupling portion of the unit substrate A _1, performs the division of the unit substrate A ₁ ( S5). At this time, the unit substrate A ₁
Since it is connected to the substrate on its left side, after division, it falls to the right with respect to the upper blade 34A and passes through the inside of the right leg 41A of the guide shown in FIG. Four
5A above. Then, the unit substrate A ₁ is finally stored in the right rack 44A.

When the division of the unit substrate A ₁ is completed, the process proceeds to the processing of S6, where the movable conveyor is moved in the X direction to perform the same positioning and division of the substrate B ₁ . Unit board B
_{Since 1} is connected on the right side, after being divided, it falls to the left with respect to the upper blade 34A and passes through the inside of the left leg 41B of the guide shown in FIG. 4, and the second fixed conveyor on the left side. 45
B is reached. And finally, the left rack 44B
It is stored inside.

The division similar to the above is performed for the unit substrates A ₂ and B ₂
Do about. The unit board A ₂ is the same as the unit board A ₁ ,
It is stored in the tray on the right side. Then, the unit board B ₂ is housed in the tray on the left side similarly to the unit board B ₁ . As a result, as shown in FIG. 7, the type A unit substrate and the type B unit substrate are separated (S7). In the control device, the coordinates of the connecting portion of each unit board are set and stored, and the type of each board can also be set and stored. The control device determines whether or not the division of the type A and type B unit boards is completed, and continues the division of the board until the division is completed.

In step S8, while the substrate is being divided, the substrate to be divided next is supplied from the rack 20 on the right side onto the fixed conveyor 24 on the right side.
It is in a state of waiting above.

In the process of S9, after the sorting of the type A unit substrate and the type B unit substrate is completed, the movable conveyor 18 is moved to the start position as shown by an arrow 108 in FIG. The substrate is transferred to the left fixed conveyor 26 as indicated by arrow 110, and the substrate is returned to the left rack 22.

Next, in S10, the substrate waiting on the fixed conveyor 24 on the right side is moved to the movable conveyor 18 at the start position, and the same process as S3 to S9 is performed to remove the substrate. Divide and separate unit boards. Then, the control device alternately divides the boards in the left and right racks, and determines whether or not the division of the unit boards of types A and B has been completed for all the boards in the left and right racks. Until then, the substrate division and the unit substrate separation are continued (S11).

When the division of the type A and type B unit substrates has been completed for all the number of substrates, the process proceeds to step S12 to divide and separate the other types of unit substrates, for example, as shown in FIG. Then, the division of the type C unit board and the type D unit board is continued in the same manner as the division of the type A unit board and the type B unit board.

Then, the processing shifts to S13, and a series of processing is performed at the stage when division and separation of all kinds of unit boards are completed for all the boards stored in the left and right racks 20 and 22 in advance. finish. The number of boards stored in the left and right racks may be set and stored in a predetermined storage area of the control device in advance.

After the separation of the two types of unit boards, the unit boards of the respective types are taken out from the left and right racks, and thereafter, the other two types of unit boards to be divided are not mixed. To do. That is, after the sorting of the unit boards of the type A and the type B is completed and before the sorting of the unit boards of the type C and the type D is started, the type A and the type B are loaded from the left and right racks.
Take out the unit substrate of. However, this does not apply when a mixture of plural types of unit substrates is allowed.

According to the embodiment described above, the unit substrates divided from the substrate can be classified according to their types. Then, the classification according to the type of substrate can be easily performed by changing the position of the connecting portion of the unit substrate with respect to the substrate. That is, it is possible to control whether the board can be stored in the right rack or the left rack depending on whether the connecting portion is formed on the right side or the left side of the unit board. In the present invention, the type means
The concept includes not only characteristics associated with the unit substrate itself such as a difference in circuit pattern, but also characteristics not directly associated with the unit substrate such as a difference in delivery destination of the unit substrate.

Furthermore, while one substrate is being divided, the other substrate to be divided next is in a standby state, so that it is possible to quickly enter the next division and classification, and the efficiency of division and classification is improved. be able to.

In this embodiment, the unit board is sorted according to which of the left and right sides of the unit board the connecting portion of the unit board is formed. However, the left or right side of the unit board is divided last. Also by this, the unit substrate can be divided. That is, even if the periphery of the unit substrate has not been punched out, the unit substrate falls on the guide 40 shown in FIG. 4 centering on the side where the unit substrate is divided at the end, so that the substrates can be separated. Become.

Further, in the present embodiment, the divided unit boards are divided into the left and right conveyors 45A and 45B to perform the division of the unit boards, but the divided unit boards may be separated by a single conveyor. In this case, the division order of the unit boards may be set and stored in the control device, and the unit boards may be sorted according to the order of the unit boards sequentially conveyed. At this time, a plurality of trays for accommodating the unit boards of each type are provided, and the trays are moved to receive the unit boards while the unit boards in the order of accommodating in each tray are conveyed. Good.

Although the substrate is divided by a blade, any known dividing means such as a laser or a rotary cutter can be used. Furthermore, it is also possible to configure so that three or more types of unit substrates can be separated at the same time. Further, in this embodiment, the substrate side is moved with respect to the dividing blade, but the dividing blade side may be moved, or both of them may be moved. The moving mechanism on the substrate side and the moving mechanism on the split blade side may be rotatable. Furthermore, the order in which the unit substrates are divided can be set arbitrarily. That is, instead of alternately dividing the type of unit substrate to be separated, one type of unit substrate is continuously divided, and the remaining type of unit substrate is continuously decomposed. You can

[0037]

As described above, according to the present invention, since the boards can be sorted according to the type of the divided unit boards, different unit boards such as circuit patterns and mounted electronic components are mixed after cutting the boards. It is possible to divide the substrate without doing so.
