Detailed Description

Next, embodiments of the present invention will be described with reference to the drawings.

As shown in fig. 1 to 4, a is a conveyor belt, which receives the supplied large oval substrate X on the upper surface and conveys it forward.

As is known, the conveyor belt a is configured by mounting an endless belt 2 between a head pulley 1 and a tail pulley (not shown), and is provided with numerous small holes 3 penetrating the front and back surfaces over the entire length of the belt 2, and a downstream suction device 4 and an upstream suction device 5 which are disposed below the head portion of the carrier-side belt 2 of the conveyor belt a and suck the lower surface (inner surface) of the belt 2. The large oval substrate X on the belt 2 can be stably conveyed by sucking the substrate by the downstream suction device 4 and the upstream suction device 5.

In the illustrated case, the downstream suction device 4 and the upstream suction device 5 are used in a tank 7 having a suction port 6 in a ceiling wall overlapping the belt 2, and the inside of the tank 7 is sucked by a hose (not illustrated) connected to the tank 7.

Of course, when the large oval substrate X is carried out forward on the belt 2 of the conveyor a, the substrate X is pushed into the box 7 and floated from the upper surface of the belt 2.

Further, a first gate-shaped moving body C is provided directly above the head of the conveyor belt a (between the downstream suction device 4 and the upstream suction device 5, and between the downstream suction device 4 and the head pulley 1 in front), and the first gate-shaped moving body C is moved forward and backward by a numerically controlled moving device B.

As shown in fig. 1, the first gate-shaped moving body C is composed of a horizontal member 8 and

vertical members

9 and 9 projecting downward from both left and right ends of the horizontal member 8. As shown in fig. 1, the first moving device B is composed of two rails 10 extending forward from both sides of the head of the conveyor a and a slider 11 provided at the lower end of the vertical member 9 and slidably engaged with the rails 10, and the first gate-shaped moving body C is moved forward and backward by the rails 10 and a numerical control linear motor 12 provided on the opposite surface of the slider 11, but the present invention is not limited thereto, and for example, a mode in which a male screw is reversibly driven by a motor and a female screw is held by the slider 11 (not shown) may be used.

The first gate-shaped moving body C is provided with a first cutter 15, the first cutter 15 is moved above the conveyor a by a reciprocating device D in the left-right direction and is lowered by a cylinder lifting device 13, and a dicing line 14 (see fig. 9) is cut between both side edges of the upper surface of the large oval substrate X, the dicing line 14 being used to divide the large oval substrate X into a tab shape.

In addition to the dicing lines 14, the first cutter 15 also cuts dicing lines 17 (see FIG. 5), and the dicing lines 17 are used to divide the end members 16 at the edges in the carrying-out direction of the rectangular substrate X-1.

In order to separate the end member 16 from the cutting line 17, the first gate-shaped moving body C is provided with a cutting bar 19 which is lowered by an extending action of an illustrated cylinder as a lifting device 18.

Thus, the rectangular substrate X-1 without the end member 16 can be carried out.

Further, two rails 20 are provided between the left and right vertical members of the first gate-shaped moving body C, a horizontal plate 22 has a slider 21 slidably engaged with the rails 20, left and right first pads 24 are provided on the plate 22, and the first pads 24 are lifted and lowered by the action of a cylinder serving as a lifting device 23, so that the stick-shaped substrate X-1 can be held and conveyed forward.

The transport of the substrate X-1 in the form of a stick can be performed by providing the linear motor 12 with a forward/backward moving device 25, and the forward/backward moving device 25 can be transported to the cutting position of the end member 16 by using a motor or the like, but the present invention is not limited thereto, and the transport can be performed only by the linear motor 12.

As shown in fig. 4, two rails 26 are provided on the first gate-shaped moving body C, a slider 28 of a support plate 27 of the first cutter 15 is slidably engaged with the rails 26, and the first cutter 14 is moved independently by a linear motor 29 provided on the facing surface of the first gate-shaped moving body C and the support plate 27.

As shown in fig. 2, 4, and 5, the plate 22 is slid in the left-right direction by the linear motor 30 provided on the facing surface of the first gate-shaped moving body C and the plate 22, whereby the positions of the left and right first pads 24 can be adjusted.

A first pick-and-place device D is provided between the lower downstream suction device 4 and the upstream suction device 5 of the belt 2 directly above the line of travel of the first cutter 15, and picks-and-places the large oval substrate X from the cut line by swinging the opposed edges in the vertical direction.

As shown in fig. 1, 2, 3 and 4, the first tab dividing means D is constituted by swing plates 32, a pin 33, and a push-up means 34, the

swing plates

32, 32 are disposed forward and backward in the moving direction of the belt 2 so that opposite edges (for division) are forward and backward in the moving direction of the belt 2, the pin 33 is swingably supported on opposite edges of the swing plates 32, and the push-up means 34 is a cam, a cylinder or the like for pushing up the opposite edges of the swing plates 32 below the opposite edges of the swing plates 32. The upper pushing device 34 pushes up and divides the dicing line 14 as the opposing edges of the two swing plates 32 rise, but the present invention is not limited to the above configuration, and other configurations can be used to achieve the object.

A traveling carriage 36 that travels forward and backward by the traveling device 35 is provided in front of the conveyor a (between upstream and forward of the pulley 1).

The moving means 35 is a linear motor as the moving means 35, which is configured such that a slider 38 of the movable carriage 36 is slidably engaged with a rail 37 in the front-rear direction, and a surface where the slider 38 and the rail 37 overlap is provided, but the moving means is not limited thereto, and may be configured by a male screw operated by a motor and a female screw supported by the male screw.

The movable carriage 36 is provided with a table 39 having a suction and holding function, and the table 39 receives the tab-shaped substrate X-1 supplied from the first mat 24 to the upper surface.

Next, the table 39 rotates the rotation shaft 42 by 90 ° (on the plane) by the motor 41 of the rotating device.

As shown in fig. 7, the table 39 supports the upper end of a rotating shaft 42 of a motor 41 mounted on the movable carriage 36, and a large number of suction ports 43 are provided in the ceiling wall of the hollow table 39 as a suction holding function, and the stick-shaped substrate X-1 is sucked and held on the upper surface of the table 39 as the inside of the table 39 is sucked and held.

In this way, after the end material 16 is divided by the cutting bar 19 and the divided end material 16 falls from the front of the head pulley 1 of the conveyor a, the table 39 is moved to the rear by the moving device 35 and the table 39 is brought close to the head pulley 1 and stopped, and the stick-shaped substrate X-1 is transferred from the conveyor a onto the table 39 by the first mat 24. The reason for this is that the cutting bar 19 is smoothly cut and dropped in front of the head pulley 1 of the conveyor a, and thereafter the moving carriage 36 is moved to the head pulley 1 side by the moving device 35.

A second portal moving body F is provided between the upstream side and the front side of the leading end of the conveyor a, and the second portal moving body F is moved forward and backward on the upper side of the traveling carriage 36 by the second moving device E.

The longitudinal movement (back and forth movement) of the second portal-shaped moving body F is the same as that of the first portal-shaped moving body C, and therefore, a detailed description thereof is omitted.

The second portal-shaped moving body F is provided with a slide base 46, and the slide base 46 is slid in the left-right direction by a numerically controlled moving device 45.

In the case of the slide guide in the left-right direction of the slide base 46, the slider 48 is slidably engaged with the guide 47, the guide 47 is provided above and below the surface of the second gate-shaped movable body F facing the first gate-shaped movable body C, the slider is supported by the slide base 46, and the numerically controlled moving device 45 uses a linear motor provided on the facing surface of the second gate-shaped movable body F and the slide base 46.

Next, the sliding base 46 is provided with a plurality of second cutters 50 having a head swinging function 49, and the plurality of second cutters 50 are arranged on the sliding base 46, can freely adjust their positions, and are respectively lowered by the lifting device 31, and cut one or more irregular cutting lines Y on the upper surface of the stick-shaped substrate X-1.

A lifting plate 52 which can be lifted and lowered by a longitudinal guide 51 is provided on the slide base 46, a mounting base 54 which applies downward pressure by a cylinder 53 is provided on the lifting plate 52, and a second cutter 50 having a head swing function 49 is provided on the lifting plate 52.

Thus, one or more irregular dicing lines Y (see FIG. 9) can be scribed on the tab substrate X-1.

Of course, the dicing may be performed by processing a plurality of dicing lines 14 between both ends of the short edge of the tab substrate X-1 and acquiring a plurality of small ellipses as shown in fig. 9 in each processing region, or may be performed by acquiring a large ellipse as shown in fig. 13.

Then, when the second cutter 50 cuts the irregularly shaped cutting lines Y, it is needless to say that the half-cut lines 81 (see fig. 9) are cut at the corners in each region to facilitate the work of dividing and separating the end material, and the cutting lines Z are cut between the large oval irregularly shaped cutting lines Y arranged as shown in fig. 13.

The stick-shaped substrate X-1 cut out the abnormal-shaped cutting line Y by the second cutter 50 is taken up by the second pad 53, the second pad 53 is lifted by the cylinder 73 provided in the second portal moving body F, the stick-shaped substrate X-1 is supplied to the delivery conveyor 61 disposed on the front side of the advance stop position of the table 39, and the subsequent processing is performed, for example, by dividing the outer end member of the abnormal-shaped cutting line Y for forming the small, medium, or large oval product size by a robot arm (see japanese utility model registration No. 3223121, japanese utility model registration No. 3221293, or japanese utility model registration No. 3219804).

As shown in fig. 8, the second pad 53 is installed on a slide plate 65 which is movable up and down by a cylinder 66, the slide plate being slidable in the left-right direction by a slider 63 engaged with a rail 62 of the second door-shaped movable body F, and slidable in a left-right position adjustment position by a 3 rd moving device 64 such as a linear motor, and the slide plate 65 being adjustable in the up-down position (height) by the cylinder 66.

In addition, a second dividing device G for making the opposing edges of the front and rear swing plates 32 intersect at right angles in the moving direction of the feeding conveyor 61 is disposed at the downstream portion of the feeding conveyor 61, and the table 39 is rotated by 90 ° to change the direction so that the cutting lines 14 of the tab-shaped substrate X-1 divided into small ellipses intersect at right angles in the moving direction of the feeding conveyor 61 and the short edges at both ends of the tab-shaped substrate X-1 are positioned in front of and behind the moving direction of the feeding conveyor 61, and the direction of the tab-shaped substrate X-1 can be changed by rotating the table 39 so that the cutting lines Z of the large ellipse-shaped substrate cross the moving direction of the feeding conveyor 61 as shown in fig. 15 when the cutting lines Z of the large ellipse-shaped substrate are positioned in front of and behind the moving direction of the feeding conveyor 61, as shown in fig. 14 to 15.

The configuration of the pivot of the swing plate 32 of the second dividing device G and the push-up device 34 are the same as those of the first tab-shaped dividing device D, and therefore, detailed description thereof is omitted.

It is known that the accurate position of the scribe line formed by the first cutter 15 or the second cutter 50 can be corrected by reading the mark (not shown) of the large oval substrate X or the stick-shaped substrate X-1 with the cameras P-1 and P-2 mounted on the first gate-shaped moving body C and the second gate-shaped moving body F, and rotating the table 39 clockwise or counterclockwise by rotating the rotating shaft 42 by the reading.

In the figure, reference numeral 75 denotes a transfer suction pad for transferring the substrate X-1 to the carry-out conveyor 61. Reference numeral 76 denotes a suction holding device for the substrate X-1.
