Description

  The present invention relates to an end material removing apparatus that removes an end material separated from a substrate.

  Generally, a manufacturing process for manufacturing a liquid crystal display panel or the like includes a dividing process of cutting out a unit substrate of a desired size from a large-area substrate called a mother substrate. In this case, the mother board is provided with an extra area between adjacent unit boards or around the mother board. For this reason, when a unit board | substrate is cut out in said dividing process, this excess area | region becomes an end material. After the end material is separated from the mother substrate, the end material is dropped from a cradle or the like of the mother substrate (for example, Patent Document 1).

JP 2002-338284 A

  However, when the end material is divided as described above and dropped as it is, the end material may enter a bearing of a scribe unit disposed below the substrate cradle. As a result, a malfunction of the scribe unit may occur.

  The present invention has been made to solve such a problem, and it is an object of the present invention to suppress an end material cut from a substrate from causing malfunction of a substrate cutting mechanism or the like.

  A main aspect of the present invention relates to a scrap material removing apparatus. The scrap material removing apparatus according to this aspect includes a first transport unit that supports and transports a substrate, and a second transport unit that receives and transports the substrate unloaded from the first transport unit. And a dividing unit that is arranged between the first transfer unit and the second transfer unit and divides a protruding portion of the substrate protruding into a space between the first transfer unit and the second transfer unit. When the projecting portion serving as an end material protrudes from the first transport portion side by the dividing portion, the projecting portion serving as the end material is gripped from the front side in the transport direction of the substrate. When projecting from the transport unit side, the gripping unit grips the projecting portion from the rear side in the transport direction of the substrate.

  According to the end material removing apparatus according to this aspect, since the divided end material is gripped by the grip portion, the end material does not fall and enter the mechanism portion or the like of the device. Therefore, it is possible to suppress the malfunction of the apparatus caused by the scrap material.

  In the scrap material removing apparatus according to this aspect, the gripping portion is supported by a support portion so that the gripping direction can be rotated 180 ° so as to grip the protruding portion from both the front side in the transport direction and the rear side in the transport direction. It can be set as a structure. According to this configuration, since only one gripping portion needs to be provided, the gripping portion can be reduced in size. Therefore, the gripping part can be positioned smoothly in the space between the first transport part and the second transport part.

  In this case, the edge material removing apparatus according to this aspect may include a lifting unit that moves the support unit up and down, and a transfer unit that transfers the support unit in the transport direction of the substrate. If it carries out like this, the direction of holding of a holding part can be changed smoothly, without expanding the space between the 1st conveyance part and the 2nd conveyance part.

  Further, the end material removing apparatus according to this aspect may be configured to change the direction of gripping by the gripping portion when the support portion is moved up and down and transferred in the transport direction.

  Further, when the end material removing apparatus according to this aspect is located below the dividing portion, the end material removed by the grip portion is released to the collection portion. It can be configured to be discarded. If it carries out like this, it can suppress reliably that an end material enters into a parting part.

  In this case, the end material removing apparatus according to this aspect releases the gripping by the gripping portion and removes the end material gripped by the gripping portion in the step in which the gripping portion is lowered from the gripping position of the protruding portion. , It can be configured to be discarded in the recovery unit. If it carries out like this, since the path | route which continues holding | grip an end material can be shortened, it can suppress that an end material falls from a holding part accidentally at the time of transfer of an end material.

  Further, in the scrap material removing apparatus according to this aspect, the dividing unit forms a scribe line on the substrate in the dividing operation, and the gripping unit moves from the gripping position of the protruding portion after the dividing operation, The end material may be separated from the substrate. If it carries out like this, since a scrap will not be isolate | separated by a parting operation | movement, it can suppress that a part cuts in a parting operation | movement.

  The end material removing apparatus according to this aspect may be configured such that the gripping portion grips the protruding portion when the dividing portion performs a cutting operation on the protruding portion. If it carries out like this, since the protrusion part used as an end material will be hold | gripped also at the time of parting, it can suppress more reliably that an end material falls.

  As described above, according to the present invention, it is possible to provide an end material removing apparatus capable of suppressing the operation of an end material divided from a substrate from causing a malfunction of a substrate cutting mechanism or the like.

The XY plane is parallel to the horizontal plane, and the positive Z-axis direction is the vertically downward direction.

  FIG. 1 is a side view schematically showing a configuration when the end material removing apparatus 1 is viewed in the negative Y-axis direction.

  The scrap material removing apparatus 1 includes a first transport unit 110, a second transport unit 120, a dividing unit 200, a gripping unit 300, a support unit 400, an elevating unit 500, a transfer unit 600, a recovery unit 710, 720.

  The 1st conveyance part 110 and the 2nd conveyance part 120 are comprised by the belt conveyor. The first transport unit 110 supports and transports the substrate 10. The second transport unit 120 receives the substrate 10 unloaded from the first transport unit 110 and supports and transports the substrate 10. The conveyance direction of the substrate 10 is the X axis positive direction.

  The dividing unit 200 is disposed between the first transport unit 110 and the second transport unit 120. The dividing unit 200 divides the protruding portion of the substrate 10 protruding into the space between the first transfer unit 110 and the second transfer unit 120. The dividing unit 200 includes a pair of scribe units 210 arranged vertically. The upper scribe unit 210 forms a scribe line on the upper surface of the substrate 10, and the lower scribe unit 210 forms a scribe line on the lower surface of the substrate 10. The dividing portion 200 is supported by an arch-shaped support member. In FIG. 1, illustration of support members positioned on the Y axis positive side and the Y axis negative side of the pair of scribe units 210 is omitted for convenience. . In addition, a space 201 through which the gripping unit 300 and the lifting unit 500 move in the X-axis direction is provided below the dividing unit 200.

One shaft 401 is provided for one grip portion 300. Two support members 402 are provided for one shaft 401. The support member 403 extends in the Y-axis direction and supports the lower end of the support member 402.

  The elevating unit 500 includes a rail 501 and a support member 502. One rail 501 is provided on each of the Y-axis positive side and the Y-axis negative side of the support member 403. The support member 502 extends in the Y-axis direction. The two rails 501 are installed on the upper surface of the support member 502. The support part 400 is supported by the two rails 501 so as to be movable in the Z-axis direction along the two rails 501.

  FIG. 3 is a side view schematically showing a configuration when a part of the scrap material removing device 1 is viewed in the negative X-axis direction.

  The gripping unit 300 includes two gears 321 and a motor 322 inside the housing member 314. The gears 321 are fixed to the two shafts 312 respectively, and the two gears 321 mesh with each other. The drive shaft of the motor 322 is connected to one of the two shafts 312.

  When the motor 322 is driven, the shaft 312 to which the drive shaft of the motor 322 is connected rotates around the Y axis. At this time, since the two gears 321 mesh with each other, the other shaft 312 also rotates in accordance with the rotation of one shaft 312. As a result, the two gripping members 311 rotate around the shafts 312 installed as the centers of rotation. At this time, since the rotation directions of the gears 321 are opposite to each other, the tip portions of the gripping members 311 are brought close to each other or separated from each other. The protruding portions of the substrate 10 are gripped by the pair of gripping members 311 by bringing the tip portions of the gripping members 311 closer to each other. When the tip portions of the gripping members 311 are separated from each other, the end material 11 (see FIGS. 9 and 17) gripped by the pair of gripping members 311 is released.

Then, the substrate 10 supported by the first transport unit 110 is transported in the X-axis positive direction by the first transport unit 110 and protruded into the space between the first transport unit 110 and the second transport unit 120. When the protruding portion of the substrate 10 protruding from the first transport unit 110 moves to the gripping member 311 of the gripping unit 300, the gripping member 311 is rotated about the shaft 312. Thereby, as shown in FIG. 4, the protruding portion of the substrate 10 is held by the holding member 311.

  Subsequently, as shown in FIG. 5, the upper cutter wheel 211 is pressed against the upper surface of the substrate 10 with a stronger force than when a normal scribe line is formed, and the lower cutter wheel 211 is pressed against the lower surface of the substrate 10. Pressed against. In this state, the pair of cutter wheels 211 are transferred in the Y-axis direction. Thus, deep scribe lines that are parallel to the Y axis are formed on the upper and lower surfaces of the substrate 10. Here, the substrate 10 is not completely divided by the formation of the scribe line, and the substrate 10 positioned on the X axis positive side with respect to the scribe line is slightly different from the substrate 10 positioned on the X axis negative side with respect to the scribe line. It is connected to.

  Subsequently, as shown in FIG. 6, the pair of cutter wheels 211 is separated from the substrate 10. The elevating unit 500 is slightly transferred in the positive direction of the X axis by the transfer unit 600, and the support unit 400 is slightly transferred in the positive direction of the Z axis by the elevating unit 500. As a result, the grip 300 is moved to the lower right by a predetermined distance. By this operation, the substrate 10 is divided at the scribe line formed by the dividing portion 200, and the protruding portion of the substrate 10 held by the holding portion 300 becomes the end material 11. Since the end material 11 is unnecessary, it is discarded by the recovery unit 710 by the subsequent operation.

The Thereby, the end material 11 gripped by the grip portion 300 is lifted upward.

  Subsequently, as shown in FIG. 8, the support part 400 is transferred in the positive direction of the Z axis by the elevating part 500. Thereby, the holding part 300 which holds the end material 11 is transferred downward.

  Subsequently, as shown in FIG. 9, when the shaft 401 is rotated 90 ° clockwise as viewed in the Y-axis negative direction, the gripping unit 300 is rotated 90 ° clockwise as viewed in the Y-axis negative direction. The Thereby, the end material 11 gripped by the gripping unit 300 is positioned above the collection unit 710. Then, the gripping member 311 is rotated around the shaft 312. As a result, as shown in FIG. 9, the end material 11 is separated from the gripping portion 300 and is recovered by the recovery portion 710.

  Subsequently, as shown in FIG. 10, the elevating unit 500 is transported by a predetermined distance in the negative direction of the X axis by the transport unit 600. Thereby, the gripping unit 300, the support unit 400, and the elevating unit 500 are positioned in the space between the first transport unit 110 and the dividing unit 200. At this time, the gripping part 300, the support part 400, and the elevating part 500 pass through the space 201 located below the dividing part 200, from the X axis positive side of the dividing part 200 to the X axis negative side.

  Subsequently, as shown in FIG. 17, when the shaft 401 is rotated 90 ° counterclockwise when viewed in the negative Y-axis direction, the gripping portion 300 is rotated 90 ° counterclockwise when viewed in the negative Y-axis direction. It is rotated. Thereby, the end material 11 gripped by the gripping unit 300 is positioned above the collection unit 720. Then, the gripping member 311 is rotated around the shaft 312. As a result, as shown in FIG. 17, the end material 11 is separated from the gripping unit 300 and is collected by the collecting unit 720.

  The substrate 10 from which the end material 11 on the X-axis negative side has been removed is transported in the X-axis positive direction by the second transport unit 120, and is a break device (not shown) located on the X-axis positive side of the end material removing apparatus 1. Thus, the substrate 10 is divided along the scribe line.

  Subsequently, as shown in FIG. 18, the elevating unit 500 is transported by a predetermined distance in the X-axis positive direction by the transport unit 600. Thereby, the gripping unit 300, the support unit 400, and the elevating unit 500 are positioned in the space between the dividing unit 200 and the first transport unit 110. Also in this case, the gripping unit 300, the support unit 400, and the elevating unit 500 are transferred from the X-axis negative side of the dividing unit 200 to the X-axis positive side through the space 201 positioned below the dividing unit 200.

  As shown in FIG. 4, when the protruding portion of the substrate 10 that becomes the end material 11 protrudes from the first transfer unit 110 side by the dividing unit 200, the holding unit 300 protrudes from the front side of the transfer direction of the substrate 10. Grab the part. In addition, as shown in FIG. 12, when the protruding portion of the substrate 10 that becomes the end material 11 protrudes from the second transfer unit 120 side by the dividing unit 200, the gripping unit 300 is formed from the rear side in the transfer direction of the substrate 10. Grip 10 protruding parts. Thus, during the cutting operation by the dividing unit 200, the end material 11 that is divided from the end on the X axis positive side of the substrate 10 and the end material 11 that is divided from the end on the X axis negative side of the substrate 10. Are gripped by the gripping unit 300. Therefore, the end material 11 does not fall and enter the mechanical part or the like (for example, the rail 214 or the ball screw 215 of the scribe unit 210). Therefore, the malfunction of the apparatus caused by the end material 11 can be suppressed.

  The gripping unit 300 is supported by the support unit 400 so that the gripping direction can be rotated by 180 ° in order to grip the protruding portion of the substrate 10 from both the front side in the transport direction and the rear side in the transport direction. For example, as shown in FIG. 4, when the substrate 10 protrudes from the first transport unit 110 side, the gripping direction of the gripping unit 300 is the negative X-axis direction, and as shown in FIG. 2 When projecting from the conveying unit 120 side, the gripping direction of the gripping unit 300 is the X-axis positive direction. As described above, if the gripping direction can be reversed by 180 °, only one gripping part 300 needs to be provided in order to grip the protruding portion of the substrate 10 from both the front side in the transport direction and the rear side in the transport direction. The grip 300 provided in the end material removing apparatus 1 can be downsized. Therefore, the gripping unit 300 can be positioned smoothly in the space between the first transport unit 110 and the second transport unit 120.

  The support unit 400 supports the grip unit 300, the elevating unit 500 elevates the support unit 400, and the transfer unit 600 transfers the elevating unit 500 in the transport direction of the substrate 10. As described above, when the elevating unit 500 that raises and lowers the support unit 400 and the transfer unit 600 that transfers the support unit 400 in the transport direction, a space between the first transport unit 110 and the second transport unit 120 is provided. The direction of gripping the gripping part 300 can be changed smoothly without spreading.

  As shown in FIG. 9, when the end material 11 divided from the X-axis positive end of the substrate 10 is at a position below the dividing unit 200, the gripping by the gripping unit 300 is released, and the collection unit 710 is discarded. Further, as shown in FIG. 17, when the end material 11 divided from the X-axis negative side end portion of the substrate 10 is at a position below the dividing portion 200, the holding by the holding portion 300 is released, Discarded in the collection unit 720. Thereby, it can suppress reliably that the end material 11 enters into the parting part 200. FIG.

  In the process in which the gripping part 300 is lowered from the gripping position of the protruding portion of the substrate 10, the gripping by the gripping part 300 is released, and the end material 11 gripped by the gripping part 300 is discarded in the collecting parts 710 and 720. The step of lowering the gripping part 300 means that after the end material 11 is divided as shown in FIGS. 6 and 14, the gripping part 300 is moved downward by the elevating part 500, and the transfer part 600 moves the X-axis direction. It is the process up to just before being transferred to. Thereby, since the path | route which the holding | grip part 300 continues holding | grip the end material 11 can be shortened, it can suppress that the end material 11 falls from the holding part 300 accidentally at the time of the transfer of the end material 11. FIG.

  As described with reference to FIG. 5, the dividing unit 200 forms a scribe line on the substrate 10 in the dividing operation. Thereafter, the holding unit 300 moves from the holding position of the protruding portion of the substrate 10 illustrated in FIG. 5 to the position illustrated in FIG. 6, and separates the end material 11 from the substrate 10. Similarly, the dividing unit 200 forms a scribe line on the substrate 10 in the dividing operation as described with reference to FIG. Thereafter, the holding unit 300 moves from the holding position of the protruding portion of the substrate 10 illustrated in FIG. 13 to the position illustrated in FIG. 14, and separates the end material 11 from the substrate 10. Thus, the end material 11 is not separated by the dividing operation of the dividing portion 200, and the end material 11 is separated by moving the gripping portion 300 to the position of FIGS. Thereby, it can control that end material 11 falls in parting operation.

  When the dividing unit 200 performs the dividing operation on the protruding portion of the substrate 10, the holding unit 300 holds the protruding portion of the substrate 10 as shown in FIGS. Thus, since the protrusion part of the board | substrate 10 is hold | gripped also at the time of the cutting | disconnection operation | movement of the parting part 200, it can suppress more reliably that the end material 11 falls.

<Example of change>
Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made to the embodiment of the present invention other than the above.

  For example, in the above-described embodiment, the collection units 710 and 720 are provided below the dividing unit 200, the gripping unit 300 is lowered while gripping the end material 11, and the end material 11 is discarded into the recovery unit 710 and 720. did. However, the present invention is not limited to this, and the collection units 710 and 720 are provided above the dividing unit 200, and the gripping unit 300 rises while gripping the end material 11, and discards the end material 11 into the recovery unit 710 and 720. May be. In this case, for example, the gripping part 300 is transferred in the X-axis direction through the upper side of the dividing part 200 after discarding the end material 11. Even in this case, the end material 11 is gripped by the gripping unit 300 and discarded to the collection units 710 and 720, so that the end material 11 is prevented from falling and entering the mechanical unit of the apparatus, as in the above embodiment. Is done.

  However, in this modified example, since the gripping of the end material 11 by the gripping unit 300 is released at a position above the dividing portion 200, the possibility that the end material 11 enters the dividing portion 200 is increased. Therefore, it is preferable that the collection units 710 and 720 are provided below the dividing unit 200 as in the above embodiment.

  Further, in the above-described embodiment, the gripping unit 300 rotates 180 degrees about the axis 401 as the center of rotation, thereby causing the substrate 10 protruding from the first transfer unit 110 side and the substrate 10 protruding from the second transfer unit 120 side. And gripped. However, the present invention is not limited to this, and the gripping unit 300 may include a pair of gripping members oriented in the transport direction and a pair of gripping members oriented opposite to the transport direction. In this case, the substrate 10 protruding from the first transport unit 110 side is gripped by a pair of gripping members directed in the opposite direction of the transport direction, and after passing through the lowering of the grip unit 300 and moving in the negative direction of the X-axis, the end material 11 is recovered by the recovery unit 720. The substrate 10 protruding from the second transport unit 120 side is gripped by a pair of gripping members directed in the transport direction, and the end material 11 is recovered by the recovery unit 710 after the grip unit 300 is lowered and moved in the X-axis positive direction. To be recovered.

  In this modified example, since the pair of gripping members protrude on the X-axis positive side and the X-axis negative side of the gripper 300, the gripper 300 becomes larger in the X-axis direction. Further, as compared with the above-described embodiment, since the path where the gripping part 300 continues to grip the end material 11 becomes longer, the possibility that the end material 11 accidentally falls from the gripping part 300 when the end material 11 is transferred increases. Therefore, in order to reduce the size of the gripping part 300 and reduce the possibility that the end material 11 falls, it is preferable that the gripping part 300 rotates 180 ° as in the above-described embodiment.

  Alternatively, in this modified example, the divided end material 11 may be collected by a collection unit provided directly below the division unit 200. In this case, although the path where the gripping part 300 continues to grip the end material 11 is short as in the above-described embodiment, the direction in which the end material 11 is gripped and the direction in which the end material 11 is separated are the same. The possibility that the end material 11 enters is increased. Therefore, as in the above-described embodiment, it is preferable that the gripping portion 300 is rotated 180 °, and the direction in which the end material 11 is gripped and the direction in which the end material 11 is separated are opposite directions.

  Moreover, in the said embodiment, although the holding part 300 rotated 180 degrees, it replaces with the rotation of the holding part 300, and as shown to Fig.20 (a), (b), the holding member 311 rotates 180 degrees. May be. In this modified example, the shaft 401 is omitted, and the housing member 314 of the grip portion 300 is fixed to the support member 402. Further, an elastic body 313 is provided on both the upper side and the lower side at the end of the gripping member 311.

  In this modified example, the substrate 10 protruding from the first transport unit 110 side is gripped by the gripping member 311 in the state of FIG. 20A, and after passing through the gripping unit 300 descending and moving in the negative X-axis direction, The end material 11 is collected by the collection unit 720. Subsequently, the pair of gripping members 311 is further rotated in the opening direction from the state of FIG. 20A to be in the state shown in FIG. And the board | substrate 10 which protruded from the 2nd conveyance part 120 side is hold | gripped by the holding member 311 in the state of FIG.20 (b), and the end material 11 passes through the downward movement of the holding part 300 and a movement to a X-axis positive direction. Is recovered by the recovery unit 710.

  In the modified examples shown in FIGS. 20A and 20B, it is not necessary to provide a mechanism for rotating the gripping unit 300, so that the gripping unit 300 can be downsized. However, since the path where the gripping part 300 continues to grip the end material 11 becomes longer than in the above embodiment, the gripping part 300 is reduced as in the above embodiment in order to reduce the possibility of the end material 11 falling. Is preferably rotated 180 °.

  Moreover, in the said embodiment, as shown in FIG. 3, when the axis | shaft 312 was rotated by the motor 322, the holding member 311 opened and closed. In addition, the grip portion 300 is rotated with respect to the support portion 400 by rotating the shaft 401 by the motor 411. However, the present invention is not limited thereto, and the gripping member 311 may be opened and closed by the shaft 312 being hung on a belt, the other end of the belt being hung on a pulley, and the pulley being rotated by a motor. Similarly, the gripping unit 300 may be rotated with respect to the support unit 400 by the shaft 401 being hung on a belt, the other end of the belt being hung on a pulley, and the pulley being rotated by a motor.

  In the above embodiment, the opening and closing of the gripping member 311, the rotation of the gripping unit 300, the vertical transfer of the support unit 400, and the transfer of the lifting unit 500 in the X-axis direction are performed using a motor as a drive source. It was broken. However, the drive source is not limited to a motor, and may be an air cylinder, for example. Further, the opening / closing of the gripping member 311 and the rotation of the gripping unit 300 are performed using separate motors as drive sources, but may be performed using one motor as a drive source.

  Moreover, in the said embodiment, in formation of the scribe line performed just before cutting off the end material 11, the board | substrate 10 is not divided completely, but it is not restricted to this, The board | substrate 10 may be completely divided. In the above embodiment, as shown in FIGS. 4 and 12, since the protruding portion of the substrate 10 is gripped by the gripping portion 300 in advance, the substrate 10 is completely formed in the formation of the scribe line performed immediately before the end material 11 is cut off. Even if divided, the end material 11 is prevented from falling. In addition, when the holding | grip part 300 is held after formation of a scribe line, in order to prevent fall of the end material 11, it is preferable that the board | substrate 10 is not completely divided like the said embodiment.

  Moreover, in the said embodiment, although a pair of scribe unit 210 was provided up and down, only one of the scribe units 210 may be provided. For example, only the upper scribe unit 210 may be provided.

  Moreover, in the said embodiment, although the 1st conveyance part 110 and the 2nd conveyance part 120 were comprised by the belt conveyor, as shown in FIG. 21, the 1st conveyance part 110 has two belt conveyors. 111 and three tables 112, and the second transport unit 120 may include two belt conveyors 121 and three tables 122. A large number of holes for adsorbing the substrate 10 are provided on the upper surfaces of the tables 112 and 122. Pressure is applied to the holes of the tables 112 and 122 by an air pressure source (not shown). When the scribe line is formed, the substrate 10 is adsorbed to the table 112 by applying a negative pressure to the holes of the tables 112 and 122.

  Moreover, in the said embodiment, although the parting part 200 was provided with the scribe unit 210 which forms a scribe line, it may replace with this and may be equipped with the structure which presses a scribe line with a break bar and breaks. In this case, a scribe line is formed in an apparatus upstream of the scrap material removing apparatus 1, and the substrate 10 on which the scribe line is formed is transported in the X-axis positive direction by the first transport unit 110. Then, the substrate 10 is divided along the scribe line by the break bar of the dividing unit 200 in a state where the holding unit 300 holds the X-axis positive side or the X-axis negative side end of the substrate 10. Also in this case, the end material 11 cut off from the substrate 10 is gripped by the gripping unit 300 and discarded to the collection units 710 and 720.
