Description

  The present invention relates to a method and an apparatus for automatically dividing a substrate main body, in which a plurality of small substrates are arranged vertically and horizontally through dividing grooves or dividing holes, into small strips.

As a device that divides a substrate in which a plurality of substrates are continuous via a split groove, etc., a substrate between a pair of upper and lower upper sandwiching rollers and a lower sandwiching roller that apply a stress sufficient to bend at the boundary of the split groove, and a pair of sandwiching rollers It has been known that an upper conveying belt and a lower conveying belt that circulate in order to feed in are provided, and an upper clamping roller is formed of a tube that is held in a cylindrical shape with a predetermined internal pressure (Patent Document 1).
JP 2000-326298 A

  This is to divide between adjacent substrates in the direction perpendicular to the conveying direction at the dividing groove portions when passing between the upper and lower clamping rollers while conveying the substrates by the belt conveyor.

  By the way, the substrate has a rectangular shape as a whole, and a small substrate continuously forms a rectangular substrate body vertically and horizontally through a split groove and the like, and the outer side of the substrate body is formed by four pieces of earplates through the groove and the like. There is something to enclose. As a specific example of the small substrate, a substrate on which a chip component is mounted can be cited. In order to obtain a small substrate from such a substrate, it is required that the ear plate is first dropped to form a substrate body, and then the substrate body is sequentially divided into strips and small substrates. Of the series of processes leading to the final product, the above-described dividing apparatus can be used for each process of sequentially dividing the substrate body into strips and small substrates.

  However, the dividing apparatus can divide the substrates adjacent in the transport direction, but cannot divide the substrates adjacent in the direction orthogonal to the transport direction. Therefore, even though the strips and small substrates adjacent in the transport direction can be divided, the strips and small substrates adjacent in the direction orthogonal to the transport direction cannot be split. Since the dividing direction when making the substrate body into a strip is orthogonal to the dividing direction when making the strip into a small substrate, the substrate body is made into a strip with one dividing device, or the strip is made into a small substrate. I can only do it. Therefore, after making the substrate body into a strip with the first dividing device, the strip must be collected, and then the recovered strip must be put into the next dividing device to make a small substrate, resulting in poor work efficiency. It is difficult to automate work lines.

  In addition, the ear plate must be removed before the substrate body is passed through the above-described dividing apparatus. The reason for this is that the ear plate is divided by 180 degrees in the direction of splitting (the direction of the split groove) between the front and rear two pieces and the left and right two pieces. The earboard adjacent in the transport direction can be cracked nicely along the split groove, but the earboard adjacent in the direction orthogonal to the substrate main body and the transport direction is configured to block both sides of the substrate main body, It is because it disturbs breaking. Therefore, in order to remove the ear plate, a dedicated device other than the above-described dividing device is required, and how to incorporate the dedicated device into the automated line becomes a problem.

  The present invention was created in view of the above circumstances, and a problem to be solved by the invention is to provide an automatic substrate dividing method and apparatus capable of automating a work line until the substrate body is made into a small substrate.

  Another object of the present invention is to provide an automatic substrate dividing apparatus capable of automating the process of making a substrate with an ear plate into a small substrate.

  Therefore, the present inventor can divide the substrate body into strips with the first dividing device and the strips into small substrates with the next dividing device by arranging two conventional dividing devices using a belt conveyor in the orthogonal direction. I thought. However, it is not efficient to collect the strip on the downstream side of the first dividing device and to put the strip into the next dividing device with the orientation turned again. This is because when the substrate main body is passed through the dividing device, the strips are arranged in an orderly manner downstream of the dividing device, maintaining the form of the substrate body before dividing, and this form can be used as it is to the next dividing device. This is because if it can be input, work efficiency will be greatly improved.

  Therefore, the problem is that the conventional dividing apparatus uses a belt conveyor, and how to move the strips in orderly parallel to the two belt conveyors perpendicular to the conveying direction. It is to change. If the strip is moved on the belt by pushing it or the like, the form of the substrate body before division cannot be maintained due to friction with the belt.

  Therefore, the present invention solves this problem by adopting the following solutions. The solution of the invention of claim 1 is a plan view of a series of work steps comprising a strip forming step, a small substrate forming step, a small substrate collecting step, and a sheet collecting step. In addition to forming in a circulatory manner, the corners of the rectangular work line are provided with first to fourth delivery processes for relaying the sheets, respectively, and in the first delivery process, the sheets are received from the sheet recovery process and a strip forming process is performed. In the middle of the process, a board body transport process is provided to place the board body on the sheet. In the strip forming process, the board body transported from the first delivery process is transported while being placed on the sheet, and the primary division is performed during the transport. The belt body is pressed by the belt conveyor and divided into strips along the parting line, while the strips are aligned next to each other to maintain the rectangular shape of the substrate body before division. The strips are transported from the primary dividing belt conveyor to the second delivery process in the extending direction while being placed on the sheet. In the second delivery process, the sheet conveyed on the second roller conveyor is the conveyance direction up to that time. By pushing in the orthogonal direction, the strip is transported while being placed on the sheet in the small substrate forming process. In the small substrate forming process, the strip is transported while being placed on the sheet, and the strip is transported by the belt conveyor for secondary division during transport. While the strip is divided into small substrates along the parting line, the small substrates are aligned vertically and horizontally to maintain the rectangular shape of the substrate body before the division, and the small substrate is placed on the sheet while being placed on the sheet. The sheet is conveyed from the dividing belt conveyor to the third delivery process in the extension direction. In the third delivery process, the sheet conveyed on the third roller conveyor is perpendicular to the previous conveyance direction. The small substrate is transported while being placed on the sheet in the small substrate recovery process, and in the small substrate recovery process, the small substrate is transported by the tertiary conveyor while being placed on the sheet, and the small substrate is moved to the work line while leaving the sheet. The substrate is characterized in that it is discharged and collected outside, and in the fourth delivery process, the remaining sheet is conveyed to the sheet collection process, and in the sheet collection process, the sheet is conveyed to the first delivery process by a fourth conveyor. This is an automatic division method.

  The method of discharging the small substrate, the discharge direction, and the receiving destination of the substrate main body in the substrate main body transporting process are not limited. However, in order to make the space required for all the work processes compact, the solution of the invention of claim 2 In the small substrate recovery process, in order to discharge the small substrate, the direction of sweeping out the small substrate by the brush is set as the extension direction downstream of the work line of the small substrate recovery process, and the upstream side of the work line of the strip forming process It is desirable to provide a receiving destination for the substrate main body in the substrate main body transporting process in the extending direction.

  According to a third aspect of the present invention, there is provided a sheet forming apparatus comprising: a sheet forming device, a small substrate forming device, a small substrate collecting device, and a sheet collecting device in order of a work line including various devices formed in a rectangular shape in plan view. The first to fourth transfer devices for relaying the sheets are provided at the corners of the rectangular work line, respectively, and the first transfer device receives the sheets from the sheet recovery device and also forms the strip forming device. From the substrate body conveying device provided in the extension direction on the upstream side of the substrate, and waits until the substrate body is placed on the sheet, and then conveys the sheet on which the substrate body is placed to the strip forming device. The strip forming device is a belt conveyor for primary division. The substrate body transported from the first delivery device is placed on the sheet and transported, and the substrate body placed on the sheet is pressurized by the primary dividing belt conveyor during transportation, and the parting Dividing the substrate body into strips along the in-line, the strips are aligned side by side to maintain the rectangular shape of the substrate body before separation, and the strips are placed on the sheet from the primary dividing belt conveyor in the extending direction. The second delivery device has a second roller conveyor that is aligned with the direction of conveyance of the sheet on which the strip is placed, and a pin for pushing out the sheet on which the strip is placed between adjacent rollers. The small substrate forming device is a belt conveyor for secondary division, which is transported while being placed on a sheet, and is stripped by the belt conveyor for secondary division during conveyance. While the strip is divided into small substrates along the parting line, the small substrates are aligned vertically and horizontally to maintain the rectangular shape of the substrate body before the division, and the small substrate is placed on the sheet while being placed on the sheet. For division The third transfer device has a third roller conveyor whose rotational direction is aligned with the transfer direction of the sheet on which the small substrate is placed, between the adjacent rollers. A pin for extruding the sheet on which the substrate is placed is provided so as to be able to reciprocate toward the small substrate collection device. The small substrate collection device includes a discharge device above the downstream end of the tertiary conveyor formed of a belt conveyor. A brush that sweeps out the small substrate and leaves only the sheet is reciprocally movable, the fourth transfer device conveys the sheet remaining at the downstream end of the small substrate collection device to the sheet collection device, and the sheet collection device is a belt It is an automatic substrate splitting device which is a quaternary conveyor composed of conveyors.

  Further, according to a fourth aspect of the present invention, the discharging device forms the sweeping direction of the small substrate by the brush in the extension direction on the downstream side, and the first delivery device has the first rotating device whose rotational direction is aligned with the sheet conveying direction. It has a one-roller conveyor, and a pin that pushes out sheets between adjacent rollers is provided so as to be able to reciprocate toward the strip forming apparatus, and is arranged next to the first roller conveyor in the extension direction on the upstream side of the strip forming apparatus. And a substrate body transfer device for receiving the substrate body from the second standby stage and placing the substrate body on a sheet on the first roller conveyor.

  The above is to use the substrate body as the object to be divided, but the rectangular substrate body is surrounded by four pieces of ear plates and the substrate is divided between the ear plate and the substrate body. In order to make the whole apparatus compact as an automatic substrate dividing apparatus used for the object, a series of work devices from the first delivery device to the sheet collecting device are used as the processing device, as in the solution of the invention of claim 5, In addition to this processing apparatus, a preliminary processing apparatus is provided, and the preliminary processing apparatus has an ear drop device for taking out the substrate stacked on the cassette from above and dropping the ear plate from the substrate main body. It is desirable that the substrate body is transported to the transport device, and the ear drop device is formed in a range between the extension direction on the upstream side of the strip forming device and the extension direction on the downstream side of the small substrate recovery device.

  According to the first and third aspects of the present invention, the substrate body is divided into strips and the strips are divided into small substrates while being placed on the sheet, so that the substrate body can be divided and conveyed while maintaining the rectangle before the division. Since the method of pushing the sheet is adopted, the sheet can be moved to a process or an apparatus for dividing into small substrates without touching a strip on the sheet. In addition, the sheet is formed in a rectangular work line in plan view so that the sheet can be circulated, and the first to fourth transfer processes and devices for relaying the sheet are provided at the corners of the rectangular work line, respectively. Therefore, the sheet can be easily transferred and the work efficiency can be improved. A skillful technique is used to discharge and collect the small substrate on the sheet outside the work line while leaving the sheet.

  In the inventions of claims 2 and 4, since the collection destination of small substrates and the reception destination of the substrate main body are concentrated outside one side of the rectangular work line, it is possible to make the apparatus for performing the entire operation process compact. it can.

  According to the invention of claim 5, a substrate having a shape in which the periphery of the substrate body is surrounded by an ear plate is to be divided, but even in this case, the ear drop device is placed outside one side of the rectangular work line, and the small substrate is collected. Since it is concentrated in the same manner as the receiving destination of the substrate body, the entire apparatus can be made compact.

  As shown in FIG. 2, the substrate 1 is a rectangular flat plate (alumina substrate), and has a groove 2 formed vertically and horizontally on its surface, and a slit H is formed at intervals along the groove 2. A part where the split groove 2 and the split hole H are formed is defined as a parting line L (divided reference line) of the substrate 1. Reference numeral 3 denotes a metal film made of electrodes. The substrate 1 partitioned by the parting line L is composed of a rectangular small substrate 4 as a final product, which forms a large rectangular substrate main body 5 continuously in the vertical and horizontal directions. The ear plate 6 is covered. The ear plate 6 consisting of four pieces in total has a length in which the two front and rear pieces protrude to the left and right of the substrate body 5, and the two left and right pieces match the front and rear length of the substrate body 5. The substrate 1 divides the ear plate 6 so that only the substrate body 5 is formed, and as shown in FIG. 3, the substrate body 5 is divided along, for example, a vertical parting line L to form strips T in which the small substrates 4 are continuous in a line. After that, as shown in FIG. 4, in the case of the substrate body 5 before division, along the horizontal parting line L, the strip T is divided into small substrates 4, and the small substrates 4 become final products. .

  As shown in FIG. 1, the automatic substrate dividing apparatus removes the ear plate 6 from the substrate 1 to form a substrate body 5, and a substrate processing unit 5 to finally make the substrate body 5 into a small substrate 4. The processing apparatus 8 is divided into a series of work lines 9 composed of the processing apparatus 8 so as to be circulated in a rectangular shape, and a collection box 10 for the small substrate 4 in the processing apparatus 8 and a preliminary processing apparatus 7 are provided. It is concentrated on the outside (adjacent side) of one side of the rectangular work line 9.

  The pretreatment device 7 takes out a cassette 11 for stacking the substrates 1, an elevating device 12 for raising the substrate 1 in the cassette 11, and the uppermost one of the substrates 1 in the cassette 11, and puts it on the first standby stage 13. The substrate transfer device 15 that moves the substrate 1 of the first standby stage 13 to the second standby stage 14 and moves the substrate body 5 of the second standby stage 14 to the processing apparatus 8 and the substrate transfer device 15 The inspection apparatus 17 that reciprocates the substrate 1 moved to the one standby stage 13 between the other inspection areas 16 and the reciprocation movement of the substrate 1 moved to the second standby stage 14 to the ear drop area 18. And an ear drop device 19 for removing the ear plate 6.

  The cassette 11 has a bottomed cylindrical shape. The elevating device 12 includes an inner plate 20 on which the substrate 1 is placed inside the cassette 11. A hole is formed in the bottom of the cassette 11, and the inner plate 20 is supported by a rod 21 penetrating the hole so that the inner plate 20 can be moved up and down. In order to always adjust the uppermost substrate 1 to the reference height, each time the substrate 1 is taken, the inner plate 20 is raised by the thickness. Further, on the side of the cassette 11, the first standby stage 13 of the inspection device 17, the second standby stage 14 of the ear drop device 19, and the corners of the rectangular work line 9 of the processing device 8 are sequentially arranged. is there.

  In the substrate transfer device 15, three sets of suction nozzles (reference numerals omitted) that are suitable for adsorbing and lifting the substrate 1 are arranged at intervals on the left and right, and the three sets of suction nozzles are Substrate moving step consisting of adsorbing, ascending, laterally moving, descending and placing the substrate 1 by releasing suction from the origin and lowering from the origin is performed, and also includes raising and lateral movement to the origin after the substrate moving step. The return process is repeated. Of the three sets of suction nozzles, the apparatus that moves the substrate body 5 of the second standby stage 14 to the processing apparatus 8 is the substrate body transfer apparatus 22.

  The inspection device 17 is provided with the first standby stage 13 so as to be able to reciprocate with respect to the inspection area 16 having the collection box 10 of the small substrate 4 in the installation direction, and on the first standby stage 13 that is moved forward and stopped. The substrate 1 placed on the substrate is inspected, and for example, it is inspected visually or with an automatic discriminating device using a camera to check whether there is a defect in appearance or whether the front and back sides are correctly placed. The processing device 8 is stopped, and when it is satisfactory, the first standby stage 13 is double-moved to return to the original position.

  The ear drop device 19 is also provided so as to be able to reciprocate with respect to the ear drop area 18 having the second standby stage 14 in the direction in which the collection box 10 of the small substrate 4 is installed, and is moved forward and stopped. The ear plate 6 is split from the substrate 1 placed on the substrate, and the second standby stage 14 is moved back to the original position. The first and second standby stages 13 and 14 are reciprocated simultaneously.

  As shown in FIG. 5 or FIG. 6, the ear drop device 19 is configured so that the second standby stage 14 is a horizontal table on which the substrate main body 5 of the substrate 1 is mounted and only the ear plate 6 is protruded. The substrate 1 is fixed by sucking air from the suction holes 23 to make the suction holes 23 have a negative pressure. Claws 24 for inclining and breaking the ear plate 6 are provided above the four sides around the second standby stage 14 so as to be movable up and down.

  When the substrate 1 before division is viewed as shown in FIG. 2, the ear plate 6 having the shorter front and rear two pieces has a configuration in which the left and right ends thereof are connected to the longer ear plate 6. In order to divide the four pieces of the ear plate 6 along the parting line L, the order of the division is first the longer (left and right) ear plate 6 and then the shorter (front and rear) ear plate 6. . If the order is reversed, there is a risk that it may be left unbalanced. Although not shown in the figure, the four claws 24 are not only assembled into a rectangular frame as a whole, but the claw 24 that divides the longer ear plate 6 is divided into the shorter ear plate 6. Fix lower than the nail 24.

  As shown in FIG. 6, the claw 24 is a horizontal bar-like block, and its inner surface side (table surface side) has a wedge shape. First, as shown in FIG. 6A, the claw 24 is moved up and down by placing the substrate 1 on the second standby stage 14 and applying a negative pressure to the inside of the suction hole 23 by a suction device (not shown). The plate 6 is held in a state of protruding from the second standby stage 14. Next, as shown in FIG. 6 (2), the claw 24 is lowered and the left and right earplates 6 are pushed by the claw 24, and the earplate 6 is split from the substrate body 5 with the parting line L as a boundary. As shown in FIG. 6 (3), the cracked ear plate 6 is dropped as it is, and when the claw 24 is further lowered, the front and rear ear plates 6 are broken by the claw 24 (not shown) and fall, and the second standby stage 14 is dropped. Only the substrate body 5 remains.

  To summarize the automatic processing steps performed by the preliminary processing apparatus 7 described above, the substrate 1 is first taken out from the cassette 11 by the substrate transfer device 15 and placed on the first standby stage 13 (substrate first transfer step). Next, the inspection apparatus 17 moves the first standby stage 13 to the inspection area 16 while the substrate 1 is on the surface, and determines whether the substrate 1 is normal. The first standby stage 13 is moved to the original area (inspection process). Thereafter, the substrate 1 of the first standby stage 13 is moved to the second standby stage 14 by the substrate transfer device 15 (substrate second transfer step). Subsequently, the ear drop device 19 moves the second standby stage 14 to the ear drop area 18 while the substrate 1 is on it, drops the ear plate 6 from the substrate 1 to form the substrate body 5, and the second on which the substrate body 5 rides. The standby stage 14 is returned to the original area (ear drop process). Here, all the processes from the substrate first transfer process to the ear drop process can be regarded as one ear splitting process. Similarly, an apparatus that performs all processes from the substrate first transfer process to the ear drop process can be regarded as one ear drop apparatus. Finally, the substrate main body 5 on the second standby stage 14 is moved to the main processing apparatus 8 by the substrate transfer device 15 (substrate main body transfer step). Note that the substrate body transporting process is also a part of the first process performed in the processing apparatus 8.

  As shown in FIG. 1, the processing apparatus 8 is a substrate body 5 to be divided, a strip forming apparatus 25 that divides the substrate body 5 into strips T, and a small substrate forming apparatus 26 that divides the strips T into small substrates 4. The work line 9 is constructed by assembling the small substrate collecting device 27 for collecting the small substrate 4 and the sheet collecting device 29 for collecting the sheet 28 into a rectangular shape in plan view, and forms the work line 9 so that the sheet 28 can be circulated horizontally. It is. In addition, first to fourth transfer devices 30, 31, 32, and 33 that relay the sheet 28 from the upstream side to the downstream side of the work line 9 are provided at the corners of the work line 9 assembled in a rectangle. The first to fourth delivery devices 30, 31, 32, and 33 may construct the corners of the rectangular work line 9 or overlap the corners of the rectangular work line 9. Sometimes build. Note that the sheet 28 uses a material having flexible conductivity, and removes static electricity from the small substrate 4 that is the final product.

  The first delivery device 30 has a first roller conveyor 34 whose rotational direction is aligned with the receiving direction of the sheet 28 (in parallel with a gap), and the sheet 28 is placed between adjacent rollers of the first roller conveyor 34. A plurality of pins 35 (extrusion members) to be pushed out are arranged at intervals in the receiving direction of the sheet 28, and the plurality of pins 35 are provided so as to reciprocate toward the strip forming device 25. The rollers constituting the first roller conveyor 34 are provided with at least one driving roller 36, and the sheet 28 fed from the sheet collecting device 29 is moved to a predetermined position of the first roller conveyor 34 by the rotation of the driving roller 36, Positioning is performed so that the strip forming device 25 can be accurately fed out. When the pin 35 is reciprocated toward the strip forming device 25, the sheet 28 is fed onto the first roller conveyor 34, and the substrate body 5 is moved onto the sheet 28 from the substrate body conveying device 22 described above. It is the time after being placed on top. Note that the upper portion of the pin 35 protrudes above the roller and has a structure that interferes with the sheet 28 on which the substrate body 5 is placed.

  The strip forming device 25 is a primary dividing belt conveyor as shown in FIGS. 7 and 8, and divides the substrate body 5 along a parting line L in a direction perpendicular to the conveying direction to generate a plurality of strips T. In order to form, the upper conveyor 37 and the lower conveyor 38 are vertically opposed to each other, the substrate body 5 is sandwiched between the upper belt 39 of the upper conveyor 37 and the lower belt 40 of the lower conveyor 38, and the upper belt 39 is conveyed. And the lower belt 40 are provided with a plurality of substrate dividing units 42 and 43 that sequentially change the conveyance direction of the substrate body 5 from the upstream side to the downstream side in the conveyance unit 41 that sandwiches the substrate body 5. It is.

  The lower conveyor 38 wraps the lower belt 40 around the plurality of lower conveying rollers 44 in a circulatory manner for the purpose of conveying the substrate body 5 horizontally as a whole, and places the lower belt 40 on the substrate body 5 for mounting. The horizontal conveyor 41 is extended upstream of the conveyor 41 of the upper belt 39. On the other hand, the upper conveyor 37 wraps the upper belt 39 around the plurality of upper conveying rollers 45 in a circulatory manner for the purpose of lightly pressing the substrate body 5 from above with the upper belt 39. Further, since the upper conveyor 37 and the lower conveyor 38 are synchronized with each other as a driving source, the upper belt 39 and the lower belt 40 move at the same speed. Therefore, the upper belt 39 and the lower belt 40 are moved. The substrate body 5 sandwiched between the two can be transported even after being divided into the strips T in the rectangular shape immediately after being put in.

  The upstream substrate splitting unit 42 is composed of a combination of an upper roller 46 and a lower roller 47. An air tube roller is used as the upper roller 46, and a mulch roller made of a general metal or the like is used as the lower roller 47. The tube roller is rotatably supported so that the lower part of the tube roller is recessed by interfering with the upper belt 39 sandwiching the substrate body 5, and the upper roller 46 and the lower roller 47 are rotated by the frictional force between the upper belt 39 and the lower belt 40. Let In the drawings, the dent is emphasized rather than the actual size ratio. Then, due to the interference due to the dents, the conveyance direction of the substrate body 5 is locally changed while being placed on the sheet 28, and the sheet 28 is bent and broken along the parting line L between the adjacent strips T. At the same time, when the substrate body 5 after being split into the upper belt 39 and the lower belt 40 is sandwiched when being transported toward the downstream substrate splitting unit 43, the bending angle becomes shallower. After folding back and breaking, the adjacent strips T are flattened.

  The lower roller 47 is formed to have a size (diameter) as small as possible in order to change the conveying direction to a steep angle so that the substrate body 5 can be easily divided into strips T. In this case, since the diameter is small, it is difficult to support with a bearing. Therefore, on the lower side of the lower roller 47, on the upstream side and the downstream side, the first and second support rollers 48 and 49 on which the lower roller 47 is placed are rotatably supported via a bearing (not shown), and the conveying direction It is restricted to be immovable.

  The air tube roller of the upper roller 46 is supported eccentrically on the downstream side with respect to the lower roller 47. As shown in FIG. 9, the air tube roller is provided with a center shaft 51 that can be expanded and contracted in a flexible cylindrical tube 50 so that both ends of the tube protrude outside the tube 50, and both ends of the tube 50 are airtight. Inner and outer clamps 52 sandwiched between the inner and outer ends of the central shaft 51 are provided at both ends of the central shaft 51. Air is fed from the outside of the central shaft 51 into the tube 50 by extending the central shaft 51 while the tube 50 is inflated and clamped. The clamping force by 52 is improved.

  The central shaft 51 is provided with a piston 54 in and out of the cylinder 53 so that the piston 54 can protrude and retract, and a large-diameter flange 56 is provided at the tip of the piston rod 55 having a larger diameter than the piston 54 and at the bottom of the cylinder 53. The flange portion 56 has a tapered shape having a smaller diameter in the axial extension direction, and is a male portion of the clamp 52 and is in close contact with the inner peripheral surface of the end portion of the tube 50.

  The female portion of the clamp 52 is a cap 57 having a tapered inner wall surface that receives the flange portion 56, and the end portion of the tube 50 is screwed into the flange portion 56 from the center of the cap 57. Pinch. The screw 58 to be screwed into the flange portion 56 of the piston rod 55 has an air injection hole 59 formed along the axis, and the piston rod 55 has a communication path 60 that communicates with the air injection hole 59 and the tube 50 vertically and horizontally. It is open. By injecting air from the air injection hole 59, the tube 50 swells, and accordingly, the piston rod 55 and the flanges 56 of the cylinder 53 are pushed outward, and the piston 54 moves in the direction of exiting the cylinder 53. Maintain 50 contours. The rod-shaped piston 54 is formed in a small-diameter portion 61 with an intermediate portion in a stepped shape, and the tip of the locking pin 62 screwed in from the outside of the cylinder 53 has a smaller diameter than the inner wall surface of the cylinder 53. By projecting toward the part 61, the length by which the central shaft 51 can expand and contract is regulated. The internal pressure of the tube 50 is set to a pressure suitable for dividing the substrate body 5 into strips T.

  The downstream substrate splitting unit 43 is provided to ensure that the substrate main body 5 is not broken for each strip T by the upstream substrate splitting unit 42 and is surely split for each strip T. As described above, the rectangular substrate body 5 is divided into left and right strips for each strip T along the parting line L. However, the rectangular strips of the substrate body 5 before division are arranged in parallel in a regular manner. And the strip T is sent out to the second delivery device 31 while being placed on the sheet 28.

  The second delivery device 31 has the same structure as that of the first delivery device 30, and only the delivery direction is different, and the small substrate forming device 26 remains on the sheet 28 while the strip T sent from the strip forming device 25 is placed on the sheet 28. To send out. Reference numeral 63 denotes a second roller conveyor, and reference numeral 64 denotes a pin.

  The small substrate forming device 26 is a secondary dividing belt conveyor having the same structure as the strip forming device 25 and divides the strip T extending in the transport direction into each adjacent small substrate 4. The small substrates 4 are arranged in the vertical and horizontal directions, hold the rectangular shape of the substrate body 5 before the division, and the small substrates 4 are sent to the third delivery device 32 while being placed on the sheet 28.

  The third delivery device 32 has the same structure as that of the first delivery device 30, and only the delivery direction is different, and the small substrate collection device is provided with the small substrate 4 sent from the small substrate forming device 26 placed on the sheet 28. 27. Reference numeral 65 is a third roller conveyor, and reference numeral 66 is a pin.

  The small substrate collection device 27 is provided with a small substrate 4 discharge device 68 above the downstream end of the tertiary conveyor formed of a belt conveyor. The discharging device 68 includes a brush 67 that sweeps out the small substrate 4 and leaves only the sheet 28 so as to be reciprocally movable. When the sheet 28 reaches the predetermined position at the downstream end of the tertiary conveyor, the tertiary conveyor is temporarily stopped, and the brush 67 is reciprocated during the primary stop. As a procedure for reciprocating the brush 67, for example, the brush 67 is lowered from the reference position to a surface where the tip of the brush 67 reaches the sheet 28, and the small substrate 4 is swept out in the extending direction of the small substrate conveyance direction by the advance of the brush 67. Examples include those that are collected in the collection box 10 and then the brush 67 is retracted and raised to stop at the reference position. During this stop, the fourth delivery device 33 moves the sheet 28 left after sweeping out the small substrate 4 to the sheet collection device 29.

  The fourth delivery device 33 conveys the sheet 28 remaining at the downstream end of the small substrate collection device 27 to the sheet collection device 29, and has the same structure as the substrate main body conveyance device 22 of the pretreatment device 7. One set of suction nozzles, each of which is appropriate for sucking the sheet 28, is lowered from the origin, sucked, lifted, moved laterally, and released from the suction of the sheet 28 (the sheet 28 is dropped by the release and the sheet collecting device 29), a sheet moving process including returning to the origin by lateral movement is performed.

  The sheet collecting device 29 is a quaternary conveyor including a belt conveyor, and the sheet 28 placed on the upstream end thereof is sent downstream and finally sent to the first delivery device 30.

  To summarize the processing steps performed by the processing apparatus 8 described above, first, the sheet collection apparatus 29 sends the sheet 28 to the first roller conveyor 34 of the first delivery apparatus 30 and the driving roller 36 of the first roller conveyor 34 is driven. Then, the sheet 28 is moved to a predetermined position and stopped (the first half of the first delivery process). During the stop, the substrate body 5 is moved from the second standby stage 14 by the substrate body transfer device 22 and placed on the stopped sheet 28 (substrate body transfer step in the first delivery step). Next, the pin 35 is moved forward by the first delivery device 30 and the sheet 28 is sent to the belt conveyor for primary division of the strip forming device 25 (the second half of the first delivery process). Subsequently, the substrate main body 5 is transported while being placed on the sheet 28 by the belt conveyor for primary division of the strip forming device 25, and the substrate main body 5 is pressurized along the parting line L while being transported. While dividing each T, the strips T are aligned side by side to maintain the rectangular shape of the substrate body 5 before the division, and the second delivery device in the extending direction from the belt conveyor for primary division with the strips T placed on the sheet 28 31 (Strip formation process).

  Subsequently, the sheet 28 conveyed on the second roller conveyor 63 is pushed by the second delivery device 31 in a direction perpendicular to the conveying direction so far, whereby the strip T is transferred to the small substrate forming device 26. (2nd delivery process). Thereafter, the strip T is transported while being placed on the sheet 28 by the small substrate forming device 26, and the strip T is pressurized by the secondary dividing belt conveyor during transport, and the strip T is moved along the parting line L to the small substrate 4. The small substrates 4 are aligned vertically and horizontally while maintaining the rectangular shape of the substrate body 5 before the division, and the third substrate in the extending direction is extended from the secondary dividing belt conveyor while the small substrates 4 are placed on the sheets 28. It is conveyed to the delivery device 32 (small substrate forming process). Subsequently, the sheet 28 conveyed on the third roller conveyor 65 is pushed by the third delivery device 32 in a direction perpendicular to the conveying direction so far, and the small substrate 4 is inserted into the small substrate collection device 27. Then, the original substrate body 5 is transported while being held in a rectangular shape (third delivery step). Thereafter, the small substrate 4 is transported by the tertiary conveyor while being placed on the sheet 28 by the small substrate collecting device 27 and the sheet 28 is swept with the brush 67 to collect the small substrate 4 in the collection box 10 outside the work line 9 ( Small substrate recovery process). The remaining sheet 28 is conveyed to the sheet collection device 29 by the fourth delivery device 33 (fourth delivery step). Thereafter, the sheet collecting device 29 conveys the sheet 28 to the first delivery device 30 by a quaternary conveyor (sheet collecting step). By automatically repeating the steps from the first delivery step to the sheet collection step, the substrate body 5 is collected as the small substrate 4 and the sheet 28 is circulated.

A discharge device 68 that reverses the sheet 28 and discharges the small substrate while being conveyed downstream is provided downstream of the tertiary conveyor, and another fourth delivery device 33 is provided downstream of the small substrate discharge device 68, A discharge chute 69 for the small substrate 4 is provided below the fourth delivery device 33, and the discharge chute 69 is inclined so as to become lower toward the downstream side of the discharge device 68.

  The discharge device 68 supports the reversing plates 70 downstream of the tertiary conveyor horizontally and at substantially the same height, and connects the downstream end of the reversing plates 70 to the support shaft 71 on the downstream side. 70 is provided so as to be rotatable about 180 degrees by power with a support shaft 71 as a fulcrum. The reversing plate 70 has a suction hole 72 formed on the upper surface thereof, sucks air to create a negative pressure inside the suction hole 72, and adsorbs and fixes the sheet 28 on the upper surface, and the sheet 28 is displaced even during reversal. Hold to not. Further, the reversing plate 70 is erected in a U shape in a plan view on the downstream side of the small fence 73 so that the small substrate 4 does not fall before the reversing plate 70 rises from the horizontal to the vertical. Take it. Reference numeral 77 denotes a sheet positioning stopper.

  Another example of the fourth delivery device 33 is a conveyor in which a plurality of string belts 74 thinner than the sheet 28 are hung on the pulley 75, and the rotation shaft 76 of the pulley 75 is directed toward the conveyance direction of the sheet collection device 29. The sheets 28 placed on the plurality of string belts 74 are arranged while being spaced apart from each other and dropping the small substrate 4 downward from between the string belts 74 and between the rotation shafts 76 to guide the discharge chute 69. , And conveyed to a sheet collecting device 29 comprising a quaternary conveyor.
