On the other hand, in recent years, in order to manufacture more packages using lead frames of the same size for semiconductor packages such as SOT (Small Outline Transistor) and SOIC (Small Outline Integrated Circuit), resin molded substrates are manufactured using lead frames with staggered leads, as shown in Figure 14.

However, in the case of resin molded boards using lead frames with staggered leads, the cutting lines of the package are not aligned in a straight line, making cutting difficult using conventional cutting equipment that uses blades.

The present invention was made to solve the above problems, and its main objective is to make it possible to easily cut with a blade an object in which the cutting lines in adjacent dividing elements are set on different straight lines.

That is, the cutting device according to the present invention is a cutting device in which a plurality of dividing elements are connected by connecting parts, and cutting objects along cutting lines in adjacent dividing elements, the cutting lines being set on different straight lines, and the cutting device is provided with a cutting table that adsorbs and holds the objects, and a cutting mechanism that cuts the objects held on the cutting table with a blade, the cutting table being divided into a first table portion that adsorbs and holds one of the dividing elements and a second table portion that adsorbs and holds the other dividing element, and the first table portion and the second table portion are configured to be movable relative to each other.

The present invention, configured in this way, makes it possible to easily cut an object with a blade, in which the cutting lines in adjacent dividing elements are set on different straight lines.

Next, the present invention will be described in more detail using examples. However, the present invention is not limited to the following description.

As described above, the cutting device of the present invention is a cutting device which cuts an object to be cut along cutting lines in which a plurality of dividing elements are connected by connecting parts and in which the cutting lines in adjacent dividing elements are set on different straight lines, and which is equipped with a cutting table which adsorbs and holds the object to be cut, and a cutting mechanism which cuts the object to be cut held on the cutting table with a blade, and which is characterized in that the cutting table is divided into a first table portion which adsorbs and holds one of the dividing elements and a second table portion which adsorbs and holds the other dividing element in adjacent dividing elements, and which is configured to be movable relative to each other.
With this cutting device, the first table portion that adjoins one of the adjacent dividing elements and the second table portion that adjoins the other of the adjacent dividing elements can be moved relative to each other to position the cutting lines of the adjacent dividing elements on the same straight line or to arrange the adjacent dividing elements alternately in the up-down direction, thereby making it possible to easily cut an object in which the cutting lines of the adjacent dividing elements are set on different straight lines with a blade.

As a specific embodiment of the cutting table, the first table portion and the second table portion are configured to be movable relative to each other in the same plane so that when the connecting portion is cut by the cutting mechanism and the adjacent divided elements are separated from each other, the cutting lines of the adjacent divided elements are aligned in the same straight line.

In this configuration, the cutting mechanism cuts the adjacent divided elements while the cutting lines of the adjacent divided elements are aligned in the same straight line by the first table portion and the second table portion, thereby cutting the adjacent divided elements all at once.

In another specific embodiment of the cutting table, the first table portion and the second table portion can be configured to be movable relative to each other in the vertical direction so that, when the connecting portion is cut by the cutting mechanism and the adjacent dividing elements are separated from each other, one of the adjacent dividing elements is positioned above the other.

In this configuration, the cutting mechanism can cut adjacent dividing elements separately by cutting one of the dividing elements while one of the dividing elements is elevated relative to the other by the first table portion and the second table portion.

A specific embodiment of the cutting object is one in which the multiple dividing elements are arranged along the cutting direction by the blade, and their arrangement is divided into at least two groups, with the cutting lines of the dividing elements in one set positioned on the same straight line, and the cutting lines of the dividing elements in the other set positioned on the same straight line.
In the cutting workpiece having this configuration, it is preferable that the first table portion adsorbs the divided elements of the one set, and the second table portion adsorbs the divided elements of the other set.

When it is assumed that only one or the other of adjacent dividing elements is adsorbed and rearranged on the cutting table or removed from the cutting table, the cutting device of the present invention further includes a transport mechanism that transports the object to be cut to the cutting table, and the transport mechanism may have a transport and adsorption section that adsorbs only one or the other of the adjacent dividing elements.

In this case, it is desirable to configure the transport mechanism in accordance with the adsorption mode of the cutting table, and the transport mechanism may have a first transport adsorption section that adsorbs the dividing elements of one set, and a second transport adsorption section that adsorbs the dividing elements of the other set.

The present invention also provides a method for manufacturing cut products using the above-mentioned cutting device.

First Embodiment of the Present Invention
A first embodiment of a cutting device according to the present invention will be described below with reference to the drawings. Note that in all of the drawings shown below, for ease of understanding, some parts are omitted or exaggerated as appropriate. The same components are given the same reference numerals and the description thereof will be omitted as appropriate.

<Overall configuration of cutting device>
The cutting device 100 of this embodiment cuts a workpiece W along cutting lines CL0 to CL2 set on the workpiece W, thereby dividing the workpiece W into a plurality of cut products P (products P).

Here, as shown in FIG. 1 and FIG. 2, the cutting object W is a structure in which a plurality of divided elements W1, W2 are connected by a connecting portion W3, and the cutting lines CL1, CL2 in the adjacent divided elements W1, W2 are set on different straight lines. Each divided element W1, W2 has a plurality of chips sealed by resin molding, and here, the plurality of chips are arranged in a line. Also, leads are provided corresponding to each chip. The plurality of divided elements W1, W2 are arranged along the cutting direction (left and right direction in FIG. 1) by the blade 31 (see FIG. 3), and both ends of the divided elements are connected by a connecting portion W3. Specifically, the divided elements W1 in the odd-numbered row, which is one set, and the divided elements W2 in the even-numbered row, which is the other set, are configured so that their leads are staggered. As a result, the cutting lines CL1 of the divided elements W1 in the odd-numbered row, which is one set, are located on the same straight line, and the cutting lines CL2 of the divided elements W2 in the even-numbered row, which is the other set, are located on the same straight line. Also, the cutting line CL1 of the odd-numbered divided element W1 and the cutting line CL2 of the even-numbered divided element W2 are located on different straight lines (see FIG. 2). Note that the reference symbol CL0 in FIG. 2 is a cutting line for cutting the connecting portion W3 to separate it into the multiple divided elements W1 and W2. Also, the cutting lines CL0 to CL2 shown in each figure are imaginary lines that are intended to be cut by the blade 31, and are not shown on the actual object W to be cut.

Specifically, as shown in FIG. 3, the cutting device 100 includes a cutting table 2 that adsorbs and holds the workpiece W, a cutting mechanism 3 that cuts the workpiece W held on the cutting table 2 with a blade 31, a transport mechanism 4 (hereinafter also referred to as a loader 4) that transports the workpiece W to the cutting table 2, and an unloading mechanism 5 (hereinafter also referred to as an unloader 5) that unloads the cut product P cut on the cutting table 2 from the cutting table 2.

The cutting table 2 adsorbs and holds the workpiece W, and as shown in Figs. 4 to 6, is divided into a first table portion 2A that adsorbs and holds one of the dividing elements W1, W2, and a second table portion 2B that adsorbs and holds the other dividing element W2, for adjacent dividing elements W1, W2. The entire cutting table 2 is configured to be movable at least in the Y direction by a moving mechanism (not shown). The entire cutting table 2 may also be configured to rotate in the θ direction by a rotating mechanism (not shown).

The first table portion 2A collectively adsorbs and holds the divided elements W1 in odd-numbered rows (row 1, row 3, row 5, ...) of the cutting object W, and the second table portion 2B collectively adsorbs the divided elements W2 in even-numbered rows (row 2, row 4, row 6, ...) of the cutting object W. As shown in FIG. 6 in particular, the first table portion 2A of this embodiment is a comb-like shape in which a plurality of first placement portions 2A1 corresponding to the odd-numbered rows of divided elements W1 are connected by connecting members 2A2, and the second table portion 2B is a comb-like shape in which a plurality of second placement portions 2B1 corresponding to the even-numbered rows of divided elements W2 are connected by connecting members 2B2.

As another example, as shown in FIG. 7, the first table portion 2A may be configured in a ladder shape with both ends of a plurality of first placement portions 2A1 corresponding to the odd-numbered row dividing elements W1 connected by a connecting member 2A2, and the second table portion 2B may have a plurality of second placement portions 2B1 corresponding to the even-numbered row dividing elements W2, and the second placement portions 2B1 may be configured to be disposed between the first placement portions 2A1 of the first table portion 2A. The plurality of second placement portions 2B1 may be connected by a base member 2B3 below the first table portion 2A.

As shown in Figures 4 to 6, the first table portion 2A has a first table suction portion 21 that suctions the odd-numbered row division elements W1, and the second table portion 2B has a second table suction portion 22 that suctions the even-numbered row division elements W2. The first table suction portion 21 and the second table suction portion 22 are independent of each other. The first table suction portion 21 and the second table suction portion 22 may be configured to be able to independently switch between suction and its stop, or may be configured to be able to simultaneously switch between suction and its stop.

The first table suction unit 21 has a first suction hole 21a that opens on the upper surface of the first table portion 2A (the upper surface of the first placement portion 2A1), a first internal flow path 21b that is continuous with the first suction hole 21a and formed inside the first table portion 2A, and a first suction pump 21c that is connected to the first internal flow path 21b. The second table suction unit 22 has a second suction hole 22a that opens on the upper surface of the second table portion 2B (the upper surface of the second placement portion 2B1), a second internal flow path 22b that is continuous with the second suction hole 22a and formed inside the second table portion 2B, and a second suction pump 22c that is connected to the second internal flow path 22b. The first suction pump 21c and the second suction pump 22c may be configured to be common, and the internal flow path connected to the suction pump may be switched using, for example, a switching valve not shown. An ejector may be used in addition to the suction pump.

The first table portion 2A and the second table portion 2B are configured to be movable relative to each other along the X direction, as shown in Figures 4 and 5. Specifically, the first table portion 2A and the second table portion 2B are configured to be movable relative to each other along the X direction in the same plane, so that when the connecting portion W3 is cut by the cutting mechanism 3 and the adjacent divided elements W1 and W2 are separated from each other, the cutting lines CL1 and CL2 of the adjacent divided elements W1 and W2 are aligned on the same line. This allows the adjacent divided elements W1 and W2 to be cut in one go.

In this embodiment, the first table portion 2A and the second table portion 2B are configured such that their mounting portions 2A1, 2B1 move relatively in parallel in the X direction. The first table portion 2A and the second table portion 2B move relatively in parallel between (i) a first state (see FIG. 4) for cutting the connecting portion W3 and (ii) a second state (see FIG. 5) in which the cutting lines CL1, CL2 of the adjacent divided elements W1, W2 are aligned on the same straight line after the connecting portion W3 is cut.

As a configuration for moving the table portions 2A and 2B relative to each other in the same plane, the cutting table 2 may have a movement mechanism 8 that moves the second table portion 2B parallel to the first table portion 2A in the X direction. The first table portion 2A is fixed.

Specifically, the moving mechanism 8 has an elastic member 81, such as a spring, that biases the second table portion 2B toward the first table portion 2A, and an adjustment member 82 that is sandwiched between the connecting member 2A2 of the first table portion 2A and the connecting member 2B2 of the second table portion 2B to adjust the distance between the first table portion 2A and the second table portion 2B. The thickness of the adjustment member 82 varies depending on the portion that is inserted between the connecting member 2A2 of the first table portion 2A and the connecting member 2B2 of the second table portion 2B. The adjustment member 82 in this embodiment has a narrow portion 821 on the insertion tip side and a wide portion 822 on the base end side. The relative position of the first table portion 2A and the second table portion 2B is adjusted by the insertion amount of this adjustment member 82. Here, the wide portion 822 is inserted between the connection members 2A2 and 2B2 to establish a first state (see FIG. 4), and the narrow portion 821 is inserted between the connection members 2A2 and 2B2 to establish a second state (see FIG. 5). The insertion amount of the adjustment member 82 is adjusted by an actuator (not shown), such as an air cylinder, hydraulic cylinder, or motor.

Alternatively, the moving mechanism 8 may move at least one of the first table portion 2A or the second table portion 2B using an actuator such as an air cylinder or a motor. In this case, for example, the position adjustment amount of the even-numbered row dividing element W2 may be set in advance, and the actuator may be controlled based on the position adjustment amount. Alternatively, the arrangement of the odd-numbered row dividing element W1 and the even-numbered row dividing element W2 (e.g., characteristic parts such as edge portions and lead portions) may be image-recognized by a camera, the amount of movement for positioning the even-numbered row dividing element W2 may be calculated based on the image recognition, and the actuator may be controlled based on the calculated amount of movement.

The cutting mechanism 3 cuts the workpiece W in a straight line, and as shown in FIG. 3, includes a blade 31, a spindle unit 32 that rotates the blade 31, and a movement mechanism (not shown) that moves the spindle unit 32 at least in the X and Z directions. The rotation axis direction of the blade 31 is parallel to the upper surface of the cutting table 2, which is a direction along the horizontal direction in this example. The cutting table 2 and the cutting mechanism 3 are moved relative to each other, so that the workpiece W is cut by the blade 31.

The loader 4 transports the workpiece W from the workpiece storage section 6 (see FIG. 3) that stores the workpiece W to the cutting table 2. Specifically, as shown in FIG. 8, the loader 4 includes an adsorption block 41 provided with a transport adsorption section 411 for adsorbing the workpiece W, and a movement mechanism (not shown) for moving the adsorption block 41.

The transport suction section 411 of the suction block 41 has a suction hole 411a that opens to the bottom surface of the suction block 41, an internal flow path 411b that is continuous with the suction hole 411a and formed inside the suction block 41, and a suction pump 411c that is connected to the internal flow path 411b. The suction hole 411a is provided with a suction pad 411d made of resin, for example. The transport suction section 411 may be provided independently in two systems, one for suctioning the odd-numbered row division elements W1 and the other for suctioning the even-numbered row division elements W2.

The unloader 5 picks up the cut product P and transports it from the cutting table 2 to the cut product storage section 7 (see FIG. 3). Specifically, as shown in FIG. 9, the unloader 5 includes a suction block 51 provided with a transport suction section 511 for suctioning the cut product P, and a movement mechanism (not shown) for moving the suction block 51.

The transport suction section 511 of the suction block 51 has suction holes 511a that open to the bottom surface of the suction block 51, an internal flow path 511b that is continuous with the suction holes 511a and formed inside the suction block 51, and a suction pump 511c that is connected to the internal flow path 511b. The suction holes 511a are provided with suction pads 511d made of resin, for example. Note that in FIG. 9, the suction holes 511a in the odd-numbered rows and the suction holes 511a in the even-numbered rows are aligned in a straight line in the Y direction, but they may be offset from each other.

<Cutting Operation of Cutting Device 100>
The operation of the cutting device 100 will be described with reference to Fig. 10. The following cutting operation is performed by controlling each part by the control unit CTL (see Fig. 3).

(1) Carrying in of the workpiece W The loader 4 adsorbs and holds the workpiece W accommodated in the workpiece accommodation unit 6, and transports it to the cutting table 2. The workpiece W transported to the cutting table 2 is adsorbed and held by the first table portion 2A and the second table portion 2B of the cutting table 2 (<Adsorbing and holding the workpiece> in FIG. 10). Here, the workpiece W is positioned relative to the cutting table 2, for example, by fitting a positioning hole formed in the workpiece W with a positioning pin provided on the cutting table 2. Alternatively, the workpiece W can be positioned by fitting a positioning hole formed in the workpiece W with a positioning pin provided on the loader 4. When the workpiece W is carried in, the wide portion 822 of the adjustment member 82 is inserted between the first table portion 2A and the second table portion 2B to be in the first state (see FIG. 4).

(2) Cutting of Connecting Portions W3 The connecting portions W3 of the workpiece W suction-held on the cutting table 2 are cut by the cutting mechanism 3 (<Cutting of Connecting Portions> in FIG. 10). In this embodiment, the connecting portions W3 connecting both ends of the divided elements W1, W2 are cut. As a result, the divided elements W1, W2 of the workpiece W are separated from each other. In this state, the cutting lines CL1, CL2 of the divided elements W1 in the odd-numbered rows and the divided elements W2 in the even-numbered rows are staggered (zigzag) and are not on the same straight line but are on different straight lines.

(3) Alignment of dividing elements W2 in even-numbered rows (movement of second table portion 2B)
In a state where the connecting portion W3 is cut and the adjacent divided elements W1 and W2 are separated from each other, the second table portion 2B of the cutting table 2 is moved by the moving mechanism 8 (<Alignment of even-numbered rows> in FIG. 10). Specifically, the second state (see FIG. 5) is assumed in which the narrow-width portion 821 of the adjustment member 82 is inserted between the first table portion 2A and the second table portion 2B. When the adjustment member 82 sandwiched between the first table portion 2A and the second table portion 2B is moved from the wide-width portion 822 to the narrow-width portion 821, the second table portion 2B moves toward the first table portion 2A by the elastic force of the elastic member 81. When the narrow-width portion 821 of the adjustment member 82 is inserted between the first table portion 2A and the second table portion 2B, the cutting line CL2 of the divided elements W2 in the even rows is aligned so as to be on the same straight line as the cutting line CL1 of the divided elements W1 in the odd rows. The divided elements W1 and W2 are maintained in suction on the tables 2A and 2B.

(4) Cutting of odd-numbered and even-numbered divided elements W1, W2 After the second table 2B holding the even-numbered divided elements W2 is moved, the cutting mechanism 3 cuts the cutting lines CL1 of the odd-numbered divided elements W1 and CL2 of the even-numbered divided elements W2, which are on the same straight line (<Cutting of odd-numbered and even-numbered rows> in FIG. 10). Note that, before cutting the multiple divided elements W1, W2, a camera may be used to recognize the images to confirm that the cutting lines CL1 of the odd-numbered divided elements W1 and the cutting lines CL2 of the even-numbered divided elements W2 are on the same straight line.

(5) Transporting the Cut Products P The unloader 5 adsorbs and holds the multiple cut products P adsorbed and held on the cutting table 2, and transports them to the cut product storage section 7. Before releasing the suction of the cutting table 2, the suction pads 511d of the unloader 5 may be pressed against the multiple cut products P to prevent misalignment or suction errors of the multiple cut products P. When the unloader 5 adsorbs the multiple cut products P, the first table portion 2A and the second table portion 2B may be left in the second state, or may be returned to the first state.

Effects of the First Embodiment
According to the cutting device 100 of the first embodiment, the first table 2A, which adsorbs one of the adjacent divided elements W1, W2, and the second table 2B, which adsorbs the other of the adjacent divided elements W1, W2, are moved relative to each other in the same plane, so that the cutting lines CL1, CL2 of the adjacent divided elements W1, W2 can be positioned on the same straight line. This makes it possible to easily cut the workpiece W, in which the cutting lines CL1, CL2 of the adjacent divided elements W1, W2 are set on different straight lines, with the blade 31.

Second Embodiment of the Present Invention
Next, a second embodiment of the cutting device according to the present invention will be described with reference to the drawings. The cutting device 100 of the second embodiment is different from the first embodiment in the configuration of the cutting table 2 and the unloader 5. The other configurations are the same as those of the first embodiment.

In the cutting device 100 of the second embodiment, the first table portion 2A and the second table portion 2B are configured to be movable relative to each other in the vertical direction so that one of the adjacent dividing elements W1, W2 is positioned above the other when the connecting portion W3 is cut by the cutting mechanism 3 and the adjacent dividing elements W1, W2 are separated from each other, as shown in FIG. 11. This allows the adjacent dividing elements W1, W2 to be cut separately.

Specifically, the first table portion 2A and the second table portion 2B are configured such that their placement portions 2A1 and 2B1 move relatively in parallel in the Z direction. As shown in FIG. 11, the first table portion 2A and the second table portion 2B move relatively in parallel between (i) a first state for cutting the connection portion W3, (ii) a second state in which the dividing element W2 of the even-numbered row is positioned above the dividing element W1 of the odd-numbered row, and (iii) a third state in which the dividing element W1 of the odd-numbered row is positioned above the dividing element W2 of the even-numbered row. Here, when changing from the first state to the second state or the third state, the first table portion 2A or the second table portion 2B may be raised or lowered by a moving mechanism (not shown). Note that the moving mechanism may be configured to move by inserting an adjustment member as in the above embodiment, or an actuator such as an air cylinder, a hydraulic cylinder, or a motor may be used.

As shown in FIG. 12, the unloader 5 includes an adsorption block 51 having transport adsorption sections 512, 513 for adsorbing the cut product P, and a movement mechanism (not shown) for moving the adsorption block 51.

Specifically, the first conveying and suction section 512 is adapted to adsorb the cut pieces P of the dividing elements W1 in the odd-numbered rows (row 1, row 3, row 5, ...) of the cutting workpiece W, and the second conveying and suction section 513 is adapted to adsorb the cut pieces P of the dividing elements W2 in the even-numbered rows (row 2, row 4, row 6, ...) of the cutting workpiece W. In other words, the unloader 5 is adapted to be able to independently switch between adsorbing or stopping the adsorption of the cut pieces P of the dividing elements W1 in the odd-numbered rows and adsorbing or stopping the adsorption of the cut pieces P of the dividing elements W2 in the even-numbered rows.

The first conveying suction unit 512 has a first suction hole 512a that opens on the lower surface of the suction block 51, a first internal flow path 512b that is continuous with the first suction hole 512a and formed inside the suction block 51, and a first suction pump 512c that is connected to the first internal flow path 512b. The first suction hole 512a is provided with, for example, a resin suction pad 512d. The second conveying suction unit 513 has a second suction hole 513a that opens on the lower surface of the suction block 51, a second internal flow path 513b that is continuous with the second suction hole 513a and formed inside the suction block 51, and a second suction pump 513c that is connected to the second internal flow path 513b. The second suction hole 513a is provided with a suction pad 513d. Alternatively, the first suction pump 512c and the second suction pump 513c may be configured to be common, and the internal flow path connected to the suction pump may be switched using, for example, a switching valve not shown. In FIG. 12, the suction holes 512a in the odd-numbered rows and the suction holes 513a in the even-numbered rows are aligned in a straight line in the Y direction, but they may be offset from each other.

In the cutting operation of the cutting device 100 with this configuration, (1) the loading of the workpiece W to be cut and (2) the cutting of the connecting portion W3 are the same as in the above embodiment. The operation after the cutting of the connecting portion W3 is described below.

(3) Moving and Cutting the Even-Numbered Row Divided Elements W2 When the connecting portions W3 are cut and the adjacent divided elements W1 and W2 are separated from each other, the second table portion 2B of the cutting table 2 is raised. Then, the cutting mechanism 3 cuts the even-numbered row divided elements W2 along the cutting line CL2 that is in the same straight line (<Cutting of Even-Numbered Rows (Second State)> in FIG. 11). When the cutting of the even-numbered row divided elements W2 is completed, the second table portion 2B is lowered.

(4) Moving and Cutting the Odd-Numbered Row Dividing Elements W1 Next, the first table portion 2A of the cutting table 2 is raised. Then, the cutting mechanism 3 cuts the odd-numbered row dividing elements W1 along the cutting line CL1 that is in the same straight line (<Cutting of Odd-Numbered Rows (Third State)> in FIG. 11). After cutting of the odd-numbered row dividing elements W1 is completed, the first table portion 2A is lowered.

(5) Discharge of Cut Products P The unloader 5 adsorbs and holds the cut products P adsorbed and held on the cutting table 2, and transports them to the cut product storage section 7. Before releasing the adsorption of the cutting table 2, the suction pads 512d, 513d of the unloader 5 may be pressed against the cut products P to prevent misalignment or suction errors of the cut products P. The cut products P do not have to be discharged after the cutting of both the even-numbered and odd-numbered divided elements W1, W2 is completed. The cut products P may be discharged using the second conveying and adsorption section 513 after the cutting of the even-numbered divided element W1 is completed, and may be discharged using the first conveying and adsorption section 512 after the cutting of the odd-numbered divided element W1 is completed.

Effects of the Second Embodiment
According to the cutting device 100 of the second embodiment, the cutting lines CL1, CL2 of the adjacent divided elements W1, W2 can be positioned on the same straight line by vertically moving the first table 2A, which adsorbs one of the adjacent divided elements W1, W2, and the second table 2B, which adsorbs the other of the adjacent divided elements W1, W2, relative to each other. This makes it possible to easily cut the workpiece W, in which the cutting lines CL1, CL2 of the adjacent divided elements W1, W2 are set on different straight lines, with the blade 31.

<Other Modified Embodiments>
The present invention is not limited to the above-described embodiments.

For example, in the first embodiment, the dividing element W2 in the even-numbered row is moved (the second table portion 2B is moved), but the dividing element W1 in the odd-numbered row may be moved (the first table portion 2A is moved) to align the cutting line CL1 of the dividing element W1 in the odd-numbered row with the cutting line CL2 of the dividing element W2 in the even-numbered row.

In addition, in the first embodiment, only one of the odd-numbered or even-numbered row dividing elements W1, W2 is moved and aligned, but depending on the arrangement of the cutting lines CL1, CL2 set on the cutting object W, for example, both the odd-numbered and even-numbered row dividing elements W1, W2 may be moved and aligned.

In addition, in the second embodiment, when the cut products P of the odd-numbered row dividing element W1 and the cut products P of the even-numbered row dividing element W2 are transported together, the suction transport section of the unloader 5 may be combined into one and a common suction system may be used.

The cutting object W to be cut by the cutting device 100 of the present invention is not limited to the above embodiment, and may be a substrate such as a printed circuit board (PCB substrate) that is not resin-molded. In this case, the cutting object W is a substrate on which a cut K is made by, for example, router processing, as shown in FIG. 13, and the substrate has a plurality of division elements W1 and W2 that are roughly L-shaped in plan view connected by a connecting portion W3, and the cutting lines CL1 and CL2 in the adjacent division elements W1 and W2 are set on different straight lines. In such a cutting object W, as in the above embodiment, after cutting the connecting portion W3, the first table portion 2A and the second table portion 2B are moved relatively in the same plane, and then the cutting lines CL1 of the odd-numbered division elements W1 and the cutting lines CL2 of the even-numbered division elements W2 can be aligned and then cut at once (<Cutting with the cutting lines of the odd-numbered and even-numbered rows aligned> in FIG. 13). In addition, after cutting the connecting portion W3, the odd-numbered row dividing element W1 and the even-numbered row dividing element W2 can be cut separately by moving the first table portion 2A and the second table portion 2B relative to each other in the vertical direction (<Cutting odd-numbered rows and even-numbered rows separately> in FIG. 13).

In the above embodiments, the object W to be cut has the arrangement of the multiple dividing elements divided into two groups (odd rows and even rows), and the cutting lines CL1, CL2 are different for the odd row dividing element W1 and the even row dividing element W2. However, this is not limited to odd row dividing elements and even row dividing elements, and can also be applied to an object having multiple dividing elements whose cutting lines are not on the same line. For example, the arrangement of the multiple dividing elements of the object W to be cut may be grouped such that the two rows on the left and right are the same. In addition, the object W to be cut may have the arrangement of the multiple dividing elements divided into three or more groups.

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the invention.
