As is well known, the substrate a is obtained by scribing cutting lines in the X direction and the Y direction on both surfaces of a large panel, and dividing the cutting lines into a plurality of pieces.

Of course, at each corner portion of the cutting line B, a half-cut line B 'is drawn from the cutting line B toward the edge of the substrate a, and the half-cut line B' makes it easier to divide each edge member C.

As shown in fig. 4 and 9, a lower stage base 4 and an upper stage base 5 are provided on the mounting table 1, the lower stage base 4 is moved and guided by a left-right direction guide D (in the illustrated case, the guide D is constituted by, for example, a rail 2 and a slider 3 slidably engaged with the rail 2, but not limited thereto) and moved forward and backward by a moving device E, and the upper stage base 5 is provided on the lower stage base 4, moved and guided by a front-back direction guide D 'and moved forward and backward by a moving device E'.

The guide device D 'is the same as the guide device D, and therefore, description thereof will be omitted, and in the case of the drawing, the moving device E, E' is composed of, for example, a male screw 7 and a female screw 8, the male screw 7 is reversibly driven by a motor 6, and the female screw 8 is screwed to the male screw 7 and supported by the lower base 4 or the upper base 5, but the present invention is not limited thereto.

The upper substrate 5 is provided with a table F having a suction holding device 9 for holding the substrate a placed thereon.

For example, as shown in fig. 5 to 8, the suction holding device 9 sucks the inside of the hollow table F through a connection hose (not shown), and sucks and holds the substrate a on the table F by a group of small holes provided on the top plate of the table F.

Further, parallel horizontal rods 10 are provided on both outer sides of the long parallel edges in the left-right direction of the table F, and the rods 10 are slid by the first moving device G so as to approach and separate from the long edges of the table F.

The approaching and separating slide is performed by sliding a slider 12 on parallel guide rails 11 engaged with the mounting table 1, as shown in fig. 4, providing the slider 12 under the rods 10, driving a male screw 13 reversibly by a motor 14, bearing the male screw 13 on the mounting table 1 in the direction from the middle to both ends of the rail 11, screwing a female screw 15 on the male screw 13, supporting the respective rods 10 by the female screw 15, and sliding the rods 10 to approach and separate from each other by the reversible driving of the motor 14, thereby adjusting the position of the rods with respect to the edge of the table F.

The table F provided on the upper base 5 is rotated by a rotating device 16, and the rotating device 16 is driven by a motor.

The factors for rotating the table F by the rotating device 16 are: when the alignment mark of the substrate a is read by a camera (not shown) provided above and the parallelism of the edge with respect to the edge of the table F needs to be corrected after the reading, the table F is rotated by the rotating device 16 and corrected.

Further, a plurality of sliders 17 are provided between both ends of the two rods 10, and the plurality of sliders 17 can be individually adjusted in position by the second moving means H.

In the illustrated embodiment, the second moving device H is independently moved by a linear motor, for example, to adjust the left and right positions, but the present invention is not limited thereto, and the object can be achieved by other configurations.

Then, each slider 17 is provided with a first jaw 18 for gripping the end material C, which is used to separate the long side end material C of the substrate A.

As shown in fig. 4 to 6, the first jaws 18 are grouped vertically, fixed to the lower side, and moved up and down by the action of the cylinder 20 to grip and split (end material C).

At this time, the upper and lower first jaws 18 are inclined upward toward the front end, and twist and divide as shown in fig. 5 to 6 by the upward inclination after gripping the end material C.

Of course, the divided end material C of the long edge is separated from the end material C of the short edge by the half-cut line B', and the divided end material C is dropped into the drop port 21 and recovered.

Of course, the collision avoiding device 22 is provided in advance at the edge of the table F, and the collision avoiding device 22 prevents the first jaw 18 from colliding with the edge of the table F when moving to the gripping position, and prevents the first jaw 18 from colliding when being turned down.

The collision avoidance means 22 is formed by a downwardly inclined surface extending from the upper surface of the edge of the table F to the edge and a recessed portion extending from the peripheral surface of the table F to the inside.

A double-arm robot 24 is provided above the long edge of the table F, and second jaws 25 are provided at the tips of the two robots 24, and the second jaws 25 grip and divide the end member C on the short edge of the substrate a.

As is well known, the second jaws 25 are grouped in pairs, and the second jaws 25 are opened and closed by cylinders.

Needless to say, the second jaw 25 and the collision avoidance device 26 for the table F are provided in advance at the short edge of the table F. In this way, the end members of the long edge and the short edge of the substrate a on the table F can be divided extremely smoothly.

In the second embodiment of the present invention, the cut-out portion 31 shown in fig. 19 (V) is provided in the middle of the edge (long edge on the side shown in the drawing) of the substrate a, and the substrate a is divided, and as shown in fig. 19 (I), the contour line 32 for the cut-out portion 31 shown in fig. 19 (V) is drawn on the edge cutting line B of the substrate a, and is formed into an shape or another trapezoidal arc shape located at both ends and in the middle in the direction from the edge of the substrate a toward the inside, and an arc shape having both ends aligned with the edge of the substrate a, a front cutting line 33 for dividing the arc shape, and a half cutting line 34 connecting the cut line 33 and the contour line 32 are drawn on the inside of the contour line 32.

In addition, the cutting line 33 for front cutting is scribed to easily divide the arc-like inner portion into left and right.

As shown in fig. 3, 4, 9, and 10, a moving body 38 is provided above the front side long edge of the table F, and the moving body 38 is supported by the frame 35, guided in the front-rear direction by a guide device 36, and moved forward and backward by a moving device 37.

The guide device 36 is configured by providing a rail on the frame 35 and slidably engaging a slider of the movable body 38 with the rail in the drawing, and the moving device 37 is configured by a male screw 40 and a female screw 41 in the drawing, the male screw 40 being reversibly driven by a motor 39 and supported on the frame 35, the female screw 41 being screwed to the male screw 40 and supported on the movable body 38, and the movable body 38 being moved forward and backward in accordance with the operation of the motor 39, but the guide device is not limited to this, and may be moved forward and backward by another configuration.

The movable body 38 is provided with an extendable body 42, and the extendable body 42 extends and descends while supporting the upper end thereof. The telescopic body 42 is a multi-stage cylinder in the illustrated case, but a plurality of upper and lower stages of telescopic bodies may be extended and contracted by a linear motor, a ball screw, or the like.

The rotating body 44 is provided at the lower end of the telescopic body 42, and is rotated 180 ° on the plane by the rotating device 43 constituted by a motor, so that the directions of both ends in the front-rear direction are changed.

As shown in fig. 11 and 12, the rotating body 44 is provided at one end with a front surface pressing device J of the substrate a and a pressing body L, the pressing body L divides the portion from the front cutting line 33 of the substrate a to the edge of the substrate a as the elevating device K is lowered, and a notch 51 is provided at the edge of the table F, the notch 51 preventing the lowering of the pressing body L from being hindered (the pressing body L passes and lowers as the pressing body L lowers).

As shown in fig. 11, in the above-described pressing device J, the bracket 52 of inverted L shape lowered so as not to pass through and drop down passes through the upper end sides of the two parallel shaft members 53 in accordance with the extension action of the elevating device K by the cylinder attached to the rotating body 44, the pressing plate 55 is attached to the lower end of the shaft members 53 as the pressing device J, and both ends of the coil spring 54 fitted to the bracket 52 and the pressing plate 55 are brought into contact with each other outside the shaft members 53.

In this way, the pressing plate 55 is lowered by the elevating device K, and the substrate a is pressed onto the table F, so that the substrate a can be pressed onto the table F in a stable state.

Of course, the pressing plate 55 is formed in a shape to press only the portion between the precut line 33 and the contour line 32.

Then, the projection 57 is lowered by the action of the cylinder 56, the projection 57 presses the upper surface of the substrate A from the inside of the precutting line 33 to the edge of the substrate A, and a pressing force is applied to the upper surface of the inside of the precutting line 33 of the substrate A by the projection 57 in accordance with the pressing, thereby performing cutting.

After the division by the projection plate 57, the projection plate 57 is raised and returned by the cylinder 56, and the lowering of the carriage 52 is released by the raising and lowering device K, and the pressing of the substrate a is released.

Further, a clamping jaw 62 is provided at the other end of the rotating body 44, the clamping jaw 62 clamps upper and lower surfaces of the arc-shaped scraps 61 on both sides (see fig. 19 (II)) which remain inside the contour line 32 after the front cutting in accordance with the above-described operation, and clamps the half-cut line 34, and the clamping jaw 62 is separated from the contour line 32 by the push-in releasing device M, and then is swung by the swinging device N, and divides the scraps 61 from the contour line 32 together with the half-cut line 34.

That is, the cut-out portion 31 shown in fig. 19 (V) may be provided in the direction from the edge of the substrate a toward the inside along with the divided remainder 61, and the cut-out portion 31 may be provided at the edge of the divided and pressurized substrate a' of the end member shown in fig. 2.

As shown in fig. 11 to 16, the jaws 62 are grouped vertically, and pins 63 are provided at both outer corners of the lower jaw 62, the pins 63 are inserted into holes 64, and the holes 64 are provided in the frame 65 so as to serve as pivot points of the pins 63, so that when the lower jaw 62 is twisted and cut, the tilting swing device N is constituted, and the upper jaw 62 is lifted and lowered by the action of a cylinder 66 attached to the frame 65, and the upper and lower jaws 62 clamp the upper and lower surfaces of the substrate a.

In this way, as the cylinder 66 is extended, the lower jaw 62 is tilted (swung) by the pressing piece 67 as shown in fig. 13 to 14, so that the arc-shaped remnants 61 and 61 inside the contour line 32 of the substrate a held by the upper and lower jaws 62 are twisted and divided, and the half-cut line 34 is also divided.

In addition, when the arc-shaped remnants 61 and 61 on the left and right sides of the contour line 32 of the shape of the missing part 31 are divided, the pressing-in releasing device M slides the both remnants 61 in the direction away from the contour line 32 without causing the scratch or the crack of the dividing edge.

Therefore, as shown in fig. 15 and 16, a support hole (not shown) of a pin 72 projecting upward from a mounting seat 71 of a cylinder 70 is used as a long hole, a slider 74 is inserted into the upper jaw 62 through an inclined guide 73 whose both ends are widened toward the inner end side in the left-right direction, and the slider 74 is pushed out as a cylinder 75 is extended, so that the upper jaw 62 is pushed back in a direction away from the contour line 32. That is, the clamping of the cull 61 by the upper and lower jaws 62 is released, and as a result, defects such as scratches and cracks in the division (accompanying the cutting) do not occur. The pressing back (backward position) of the upper jaw 62 is shown at 78.

The defective portion can be smoothly removed by the front division and the rear division in this order. Then, the left and right jaws 62 are divided by a time difference from one side to the other side, so that the division without scratches can be performed more smoothly.

The telescopic body 42 is contracted to retract the rotating body 44 to a position where it is not obstructed by the moving device 37, so that the operation of the robot arm 24 is not restricted.
