Description

  The present invention relates to a workpiece transfer device for transferring a workpiece such as an electronic component.

  Conventionally, various configurations of a workpiece transfer device that transfers workpieces such as electronic components have been proposed. For example, a belt that is a work conveying means for moving a row of workpieces by intermittent advancement, a stopper that is positioned on the belt and stops advancing the row of workpieces, a workpiece that contacts the stopper, and a position immediately after the workpiece 2. Description of the Related Art There is a workpiece transfer device that includes a separator for separating a workpiece to be separated and a suction nozzle for sucking a workpiece in contact with a stopper. In this workpiece transfer device, the plurality of workpieces forming a row are moved by the belt that moves intermittently, and the workpieces forming the row stop moving when the workpiece located at the tip contacts the stopper. The separator enters between the workpiece that is in contact with the stopper and the workpiece that is positioned immediately behind the workpiece while expanding the gap between them, and separates the two. This eliminates the influence of the workpiece located immediately after the workpiece located at the tip when the workpiece is taken out by the suction nozzle (see, for example, Patent Document 1). In addition, as a device for conveying a workpiece, there is a conveyance device that conveys a workpiece by vibration due to vibration of a conveyance member that is a workpiece conveyance means.

Japanese Patent Laid-Open No. 10-335891

  However, in the workpiece transfer device described in the above publication, even if the workpiece that is in contact with the stopper and the workpiece that is positioned immediately after the workpiece are separated by the separator, the workpieces are still in contact via the separator. In addition, when considering application of the above separator to a conveying device that vibrates a conveying member that is a workpiece conveying means, even if the workpiece that is in contact with the stopper and the workpiece that is positioned immediately after it are separated by the separator The workpiece is still on the vibrating member and is in contact with the workpiece immediately after it through the separator, so that it receives vibration. Moreover, it is predicted that even if the workpiece that has been vibrated is attracted by the nozzle, it cannot be attracted well.

  An object of this invention is to provide the workpiece conveyance apparatus which can isolate | separate the workpiece | work located in the most downstream end in a conveyance direction from the workpiece | work conveyance means and the workpiece | work located immediately behind the said workpiece | work.

  In order to achieve the above object, the present invention provides a work transfer device having a frame, a drive source, a work transfer means, a receiving part, a work pressing member, a moving part, and a drive connecting part. Yes. Here, the workpiece conveying means is fixed to the frame, and a workpiece conveying groove is formed in which a plurality of workpieces are conveyed in a row. The receiving unit receives only one workpiece that is provided in the workpiece conveyance means at the downstream end of the workpiece conveyance groove in the workpiece conveyance direction and is conveyed from the workpiece conveyance groove. The work pressing member is supported by the receiving part so as to be movable, and selectively presses the work on the receiving part so as not to move.

The moving part has a work storage part for storing the work, a first position for storing the work transported by the work transporting means in the work storage part immediately downstream of the receiving part in the work transport direction, and a receiving part The second position that separates the workpiece on the receiving portion and the workpiece on the storage portion away from the workpiece can be moved along the conveyance direction of the workpiece . The drive connecting portion can be reciprocated in a direction orthogonal to the workpiece conveyance direction by a drive source. The receiving portion further includes an abutting portion that extends in the workpiece conveyance direction and can abut against the side surface of the workpiece. The work pressing part is movable in a direction approaching / separating from the contact part.

In order to press the workpiece positioned between the contact portion and the workpiece pressing portion so as not to move, a pressing means for pressing the workpiece pressing portion in a direction approaching the contact portion is supported by the drive connecting portion. Furthermore, at least one of the work pressing member and the pressing means has an elastic body. The workpiece conveying member is further supported by the drive connecting portion and extends in the moving direction of the drive connecting portion, and is supported by the moving portion, and is moved by the interlock acting member to convey the moving portion to the workpiece. And a driven member for moving in the direction. Further, the interlocking member has a first thick part and a second thick part having a thickness different from that of the first thick part in the workpiece conveyance direction. While the pressing means presses the work pressing member toward the abutting portion by the movement of the drive connecting portion in one direction, the workpiece is clamped by the workpiece pressing member and the abutting portion, and the workpiece is made immovable at the receiving portion. The follower member is in contact with the first thick part, so that the moving part is located at the first position. By further movement of the drive connecting portion in one direction, the driven member comes into contact with the second thick portion, so that the moving portion is separated from the receiving portion and located at the second position.

  According to such a configuration, since the moving unit is separated from the receiving unit, when the workpiece conveying unit is conveyed by the vibration of the vibrating body, vibration of the vibrating unit to the workpiece on the storage unit can be suppressed. . In addition, when the work on the storage unit is sucked and transferred by a suction nozzle or the like, it can be reliably sucked and transferred. Furthermore, the pressing operation by the workpiece pressing member of the workpiece in the receiving portion and the separating operation from the receiving portion of the moving portion can be performed by a single drive source via the drive connecting portion. Therefore, it is not necessary to provide a drive source, and the work transfer device can be simplified.

  Here, the pressing means includes a rod support portion fixed to the drive connection portion, a rod supported by the rod support portion so as to be movable in the moving direction of the drive connection portion, and a rod and the rod support portion. It is preferable to have a spring that is mounted and constantly urges the rod toward the work pressing member. According to such a configuration, even if the rod comes into contact with the pressing member due to the movement of the drive connecting portion, the drive connecting portion can be further moved by compressing it against the biasing force of the spring.

  According to the workpiece transfer apparatus of the present invention, the workpiece positioned at the most downstream end in the transfer direction can be separated from the workpiece transfer means and the workpiece positioned immediately behind the workpiece.

  The moving unit 26 is disposed so as to contact the receiving unit 24, and an end portion (not shown) of the moving unit 26 is attached to an LM guide (not shown) so as to be able to reciprocate in the conveying direction of the magnetic core 3. Therefore, the moving unit 26 can be moved toward and away from the receiving unit 24 along the conveying direction of the magnetic core 3. In addition, the moving unit 26 includes a storage unit 26 </ b> A on which the plate-like core 3 that has been transported to the transport unit 23 and passed through the receiving member 24 is placed. Only one plate-like core 3 can be placed in the storage portion 26A. In addition, an air suction passage 26 a for sucking the plate-like core 3 that opens to the end surface on the plate-like core 3 conveyance direction side of the storage portion 26 </ b> A is formed inside the moving unit 26. The side opposite to the storage portion 26A of the air suction passage 26a is connected to a negative pressure source such as a negative pressure pump (not shown). This negative pressure source is turned on and off by a control unit (not shown). Note that the transfer device (not shown) is disposed above the moving unit 26.

  The LM guide 27 is attached to a frame (not shown) on the side of the pressing member 25 opposite to the contact portion 24B. The LM guide 27 includes a rail 27A and a slide member 27B. The rail 27 </ b> A is provided so as to extend in a horizontal direction and a direction orthogonal to the conveying direction of the plate-like core 3. The slide member 27B has a substantially conical shape and is attached to the rail 27A so as to be slidable in the extending direction. The drive connecting portion 28 is fixed to the slide member 27B. The drive connecting portion 28 is connected to a drive source (not shown), and is provided so as to be reciprocally movable in the sliding direction (direction perpendicular to the conveying direction of the plate core 3) via the slide member 27B by the driving force. It has been.

  The pressing means 29 includes a rod support portion 29A, a rod 29B, and a second spring 29C. The rod support portion 29 </ b> A is fixed to the drive connecting portion 28. The rod 29 </ b> B is supported by the rod support portion 29 </ b> A and is movable in the moving direction of the drive connecting portion 28. Further, the rod 29 </ b> B is disposed at a position where the rod 29 </ b> B can be brought into contact with or separated from the pressing member 25 by the movement of the drive connecting portion 28. The second spring 29C is interposed between the rod 29B and the rod support portion 29A, and constantly urges the rod 29B toward the pressing member 25.

  The interlocking action member 30 is fixed to the drive connecting portion 28 and extends toward the moving portion 26 side (left side in FIG. 3) of the drive connecting portion 28. The interlocking action member 30 is composed of a thick plate portion 30A having a thick width in the conveying direction of the plate-like core 3 and a thin plate portion 30B having a width smaller than that of the thick plate portion 30A. The thick plate portion 30A protrudes in the transport direction of the plate core 3 than the thin plate portion 30B. The thick plate portion 30A faces the drive connecting portion 28 side, and the thin plate portion 30B is located at a portion extending from the drive connecting portion 28 to the vicinity of the moving portion 26 (below the moving portion 26).

  The driven member 31 includes a cam follower support portion 31A and a cam follower 31B. The cam follower support portion 31A is positioned below the thin plate portion 30B and is fixed to an LM guide (not shown) to which the moving portion 26 is fixed. Further, the cam follower support portion 31A is always urged in the anti-conveying direction of the plate core 3 by a third spring (not shown). Therefore, the above-mentioned moving part 26 is always urged toward the receiving part 24 via the cam follower support part 31 and the LM guide (not shown) by the third spring (not shown). The cam follower 31B is supported by the cam follower support portion 31A so as to be rotatable about its own axis and so as to contact the thin plate portion 30B. Therefore, the cam follower 31B is also always urged in the counter-conveying direction of the plate core 3 by the third spring (not shown) via the cam follower support portion 31.

  Next, the detailed arrangement position of the interlocking action member 30 will be described. Before the drive connecting portion 28 moves to the pressing means 29 side (a state where the rod 29B and the pressing member 25 are separated from each other by a predetermined distance), the cam follower 31B is in a positional relationship such that it abuts on the thin plate portion 30B. Even if the rod 29B and the interlocking action member 30 are moved by the movement of the drive connecting portion 28 toward the pressing means 29, and the tip of the rod 29B comes into contact with the pressing member 25, the cam follower 31B has the thin plate portion 30B (thickness in the thin plate portion 30B). It remains in contact with the portion adjacent to the plate portion 30A. Further, when the drive connecting portion 28 is moved against the urging force of the second spring 29C, the cam follower 31B is disposed so as to contact the thick plate portion 30A.

  Next, the conveying operation of the plate core 3 in the first supply unit 20 will be described. The plate-like core 3 is supplied from the parts feeder 21 to the conveying groove 22a of the linear feeder 22 in the posture shown in FIG. When the linear feeder 22 vibrates due to the vibration of a vibrating body (not shown), the plate-like core 3 moves toward the receiving portion 23 in a row. Then, the plate-like core 3 located at the tip of the plate-like cores 3 in a row passes through the receiving portion 23 and is in contact with the receiving portion 23 by the biasing force of a third spring (not shown). When the storage portion 26A is reached, the movement of the plate-like cores 3 forming a row stops (FIGS. 4A and 4B).

  At this time, a negative pressure source (not shown) is turned on, and the plate-like core 3 on the storage portion 26A is sucked with negative pressure via the air suction passage 26a of the moving portion 26. Then, as shown in FIG. 5A, the drive connecting portion 28 is moved toward the pressing member 25 by the driving force of a driving source (not shown), and the rod 29B is brought into contact with and pressed against the pressing member 25. As a result, the pressing member 25 moves toward the receiving portion 24 against the urging force of the second spring (not shown). Accordingly, as shown in FIG. 5B, the pressing portion 25A moves toward the contact portion 24B, presses the plate-like core 3 positioned on the core receiving portion 24A from the side surface, and the pressing portion 25A The plate-like core 3 is made immovable by being sandwiched between the contact portions 24B. At this time, as described above, the cam follower 31B is in contact with the thin plate portion 30B.

  Further, when the drive connecting portion 28 is moved against the urging force of the second spring 29C, the interlocking action member 30 also moves, so that the cam follower 31B that has been in contact with the thin plate portion 30B as shown in FIG. Will come into contact with the thick plate portion 30A. As a result, the cam follower 31 </ b> B moves against the urging force of the third spring (not shown) in the conveying direction of the plate-like core 3. Therefore, as shown in FIG. 6B, the moving part 26 moves in the conveying direction of the plate-like core 3 via the cam follower support part 31 </ b> A and the LM guide (not shown) and is separated from the receiving part 24. Therefore, it is possible to suppress the plate-like core 3 on the storage portion 26A from being vibrated by a vibrating body (not shown).

  Next, the negative pressure source (not shown) is turned off to stop the negative pressure suction of the plate core 3 on the storage portion 26A. Then, the plate-like core 3 on the storage portion 26A is sucked by the work suction nozzle of the transfer device (not shown) and transferred to the suction nozzle (not shown) of the first index table 10 located at the stop position S1. At this time, the movement of the moving part 26 from the receiving part 24 suppresses the vibration by the vibrating body (not shown) to the plate-like core 3 on the storage part 26A, so that the plate-like core 3 is reliably adsorbed and transferred. can do. Next, the drive connecting portion 28 is moved toward the counter pressing member 25 by a driving force of a driving source (not shown). As the drive connecting portion 28 moves, the interlocking action member 30 also moves away from the pressing member 25, so that the cam follower 31B that has been in contact with the thick plate portion 30A contacts the thin plate portion 30B (FIG. 5A). As a result, the cam follower 31B moves in the counter-conveying direction of the plate-like core 3 by the urging force of a third spring (not shown). Therefore, the moving part 26 moves in the anti-conveying direction of the plate-like core 3 via the cam follower support part 31A and the LM guide (not shown) and comes into contact with the receiving part 24 (FIG. 5B).

  Further, when the drive connecting portion 28 is moved toward the counter pressing member 25, the rod 29 </ b> B that is in contact with the pressing member 25 is separated from the pressing member 25. Along with this, the pressing member 25 is separated from the receiving portion 24 by the biasing force of the second spring (not shown). Therefore, since the pressing portion 25A is separated from the plate-like core 3 on the receiving portion 24, the plate-like core 3 can move. The plate-like cores 3 arranged in a row again move toward the moving part 26 due to vibration of a vibrating part (not shown), and move when the plate-like core 3 located at the tip reaches the storage part 26A of the moving part 26. Stop. Then, the transfer of the plate-like core 3 on the storage portion 26A to the first index table 10 is performed in the same manner as described above.

  As described above, the two operations, that is, the pressing operation by the pressing member 25 of the plate-like core 3 on the receiving portion 24 and the separating operation from the receiving portion 24 of the moving portion 26 are illustrated in one drawing via the drive connecting portion 28. Since it can be performed by a drive source (not shown) and it is not necessary to provide a drive source for each operation, it is possible to simplify the first transfer means 20 which is a work transfer means. The rod 29B is supported by the rod support portion 29A so as to be movable in the moving direction of the drive connecting portion 28, and the second spring 29C is interposed between the rod 29B and the rod support portion 29A. Therefore, even if the rod 29B contacts the pressing member 25 due to the movement of the drive connecting portion 28, the drive connecting portion 28 can further move by compressing it against the urging force of the second spring 29C.

  The transport apparatus according to the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the scope described in the claims. For example, the rod support 29A movably supports the rod 29B, and the second spring 29C is interposed between the rod 29B and the rod support 29A, but the rod 29B is fixed to the rod support 29A, and the second The spring 29C may be deleted, and the portion of the pressing member 25 with which the rod 29B abuts may be formed of an elastic body. According to such a configuration, even after the drive connecting portion 28 comes into contact with the pressing member 25, the drive connecting portion 28 can further move due to the compression of the elastic body.
