  The conventional surface mounter configured as described above has a problem when electronic components are mounted on one printed wiring board by two electronic component transfer units in order to improve mounting efficiency. This is because there is no interference when two electronic component transfer units mount the electronic component at the same time. On the other hand, during the mounting of the electronic component by one electronic component transfer unit, the electronic component of the parts feeder is not mounted. This is because there is a restriction when trying to suck with the suction nozzle of the other electronic component transfer unit.

  That is, when the other electronic component transfer unit is upstream in the X direction of one electronic component transfer unit, the suction nozzle of the head unit of the other electronic component transfer unit is upstream in the X direction from the printed wiring board position. The electronic component can be adsorbed only from the part feeder further upstream in the X direction than the support member of the one electronic component transfer unit. Similarly, when the other electronic component transfer unit is downstream in the X direction of the one electronic component transfer unit, the suction nozzle of the head unit of the other electronic component transfer unit is downstream in the X direction from the printed wiring board position. An electronic component can be adsorbed only from a part feeder further downstream in the X direction than the supporting member.

For this reason, from the position below the holding member of one electronic component transfer unit from the printed wiring board position to the upstream side in the X direction, to the position below the other holding member from the printed wiring board position to the downstream side in the X direction. In order to adsorb the electronic components of the parts feeder between the two electronic component transfer units, it is necessary to wait until the other electronic component transfer unit finishes mounting and retracts from the upper position of the printed wiring board. It was.
As a result, the conventional surface mounter has a problem that even if electronic components are mounted on a single printed wiring board by two electronic component transfer units, the mounting efficiency is not as high as expected.

  The present invention has been made to solve such a problem, and in a surface mounter in which at least two sets of electronic component transfer units move in the transport direction of the printed wiring board, a support for supporting the head unit movably is provided. It is an object of the present invention to provide a surface mounting machine in which mounting efficiency is improved without causing the other electronic component transfer unit to interfere with a member.

  In order to achieve this object, a surface mounter according to the present invention includes a transport device that transports a printed wiring board in a first direction on a base, and the first direction intersects the transport device.

For this reason, since the range in which the electronic component supply device can be provided can be expanded to the outside of the device in the first direction, a surface mounter capable of mounting many types of electronic components can be provided. In addition, for example, by providing a large number of parts feeders that supply electronic components that are frequently used, it is possible to reduce the frequency of replacement of the parts feeder due to a shortage of electronic components. Furthermore, in a surface mounter that needs to be stopped when the parts feeder is replaced, the number of stops can be reduced and mounting efficiency can be improved.

  According to the fourth and fifth aspects of the present invention, a plurality of pairs of component transfer units in which the head units are adjacent to each other are installed, so that the mounting efficiency can be further improved.

  According to the invention described in claim 6, since the number of component transfer units increases, the mounting efficiency can be further improved. According to the invention described in claim 7, since the number of head units increases, Efficiency can be further improved.

  The vertical drive device 68 includes a ball screw shaft 71 rotatably supported by the first and second frames 61 and 62 in a state of passing through the lifting member 67 in the vertical direction, and an upper end of the ball screw shaft 71. And a lifting motor 72 that rotates the ball screw shaft 71, and a ball nut 73 that is screwed to the ball screw shaft 71 and fixed to the lifting member 67.

In the suction head 55 according to this embodiment, the suction nozzle 36 moves in the vertical direction by driving by the vertical driving device 68, and the suction nozzle 36 rotates about the vertical axis by driving by the rotary driving device 69.
As shown in FIG. 4, the rotation driving device 69 and the suction nozzle 36 are positioned at the center of the head unit 24 in plan view. Specifically, the suction nozzles 36 of the four suction heads 55 mounted on the first frame 61 are arranged in a line in the X direction at a position adjacent to the lower imaging camera 56. Further, the suction nozzles 36 of the four suction heads 55 mounted on the second frame 62 are aligned in the X direction at positions adjacent to the four suction nozzles 36 on the first frame 61 side in the Y direction. Are lined up.

  That is, the head unit 24 according to this embodiment is provided with four suction nozzles 36 arranged in the X direction so as to form two rows in the Y direction. The lower imaging camera 56 is positioned in the middle of the two rows of suction nozzles 36 in the Y direction. The interval (nozzle pitch) in the X direction of these suction nozzles 36 is set to coincide with the interval (feeder pitch) between the parts feeders 8.

  The Y-direction drive device 27 that moves the head unit 24 in the Y direction with respect to the support member 32 is provided on the support member 32 and can freely move the head unit 24 in the Y direction, as shown in FIGS. The Y-direction guide rails 51 and 51 supported on the Y-direction guide rail 51, the Y-direction ball screw shaft 81 positioned between the Y-direction guide rails 51 and 51, and the Y-direction ball screw shaft 81 are screwed together. A ball nut (not shown), a hollow motor 82 (see FIG. 4) supported by the first support plate 53 of the head unit 24, and a secondary connected to one end of the Y-direction ball screw shaft 81. And a drive motor 83. A case for supporting a stator (not shown) of the sub drive motor 83 is fixed to the support member 32 through a case of the bearing member 85.

  The Y direction ball screw shaft 81 constitutes a second direction ball screw shaft in the present invention. As shown in FIG. 3, the Y-direction ball screw shaft 81 is formed so as to extend from one end portion in the Y direction of the support member 32 to the other end portion, and is supported by bearing members 84 provided at both end portions. 32 is supported in a state where it can freely rotate and movement is restricted in the Y direction.

  The ball nut and the hollow motor 82 of the Y-direction drive device 27 have the same structure as the hollow motor 34 used in the X-direction drive device 26 described above. As shown in FIGS. 4 and 5, the hollow motor 34 is attached to a bracket 85 protruding from the first support plate 53.

  The auxiliary drive motor 83 receives a reaction force when the ball nut rotates by driving the hollow motor 82, and fixes the Y-direction ball screw shaft 81 to the support member 32; The second operation state in which the Y-direction ball screw shaft 81 is rotated in the direction opposite to the direction in which the ball nut rotates by driving the hollow motor 82 is configured to be switched.

  When the sub drive motor 83 is in the first operating state, the head unit 24 moves in the Y direction with respect to the support member 32 only by being driven by the hollow motor 82. Further, if the sub drive motor 83 is in the second operation state when the head unit 24 is moved by the drive by the hollow motor 82, the head unit 24 is faster than the case where the head unit 24 is moved by the drive of the hollow motor 82 alone. Will move in.

  In the surface mounting machine 1 configured as described above, the electronic component 11 is mounted on the printed wiring board 4 so that the mounting efficiency is always increased by adopting a mounting form corresponding to the size of the printed wiring board 4. . For example, as shown in FIG. 9, when the printed wiring board 4 is relatively small, the printed wiring board 4 can be fixed at three places on the conveyors 5 and 6, and the first to third electronic components The electronic component 11 is mounted in a shared manner on the printed wiring board 4 fixed at each mounting position by the transfer units 21 to 23. The printed wiring board 4 completes the component mounting by sequentially mounting the electronic components 11 at the three mounting positions.

  The electronic component 11 is mounted in parallel in the first to third electronic component transfer units 21 to 23. In each of the electronic component transfer units 21 to 23, the X-direction moving member 25 moves in the X direction by driving by the X-direction driving device 26, and the head unit 24 moves in the Y direction by driving by the Y-direction driving device 27. Further, the suction nozzle 36 is moved up and down by driving the head unit 24 by the vertical driving device 68, and the suction nozzle 36 is rotated by driving by the rotation driving device 69.

  When the electronic component 11 is sucked by the suction nozzles 36 of the electronic component transfer units 21 to 23, the electronic component supply device 9 provided at one end portion in the Y direction of the base 2 and the other end portion are provided. Both electronic component supply devices 9 can be used.

In the surface mounter 1 according to this embodiment, since the nozzle pitch and the feeder pitch coincide with each other, the four suction nozzles 36 arranged in the X direction when the electronic component supply device 9 sucks the electronic component 11. Thus, a maximum of four electronic components 11 can be sucked at a time.
After the eight suction nozzles 36 suck the electronic component 11, the head unit 24 moves from the upper side of the electronic component supply device 9 over the X-direction guide rail 33 to the transport device 3 side.

  At this time, the head unit 24 crosses over the component recognition device 35, and the component recognition device 35 images eight electronic components 11 at a time from below. A suction position of each electronic component 11 with respect to the suction nozzle 36 is detected based on the imaging result, and the position of the head unit 24 is corrected based on the detected suction position deviation amount, and each electronic component 11 is printed on the printed wiring board. 4 is mounted at a predetermined mounting position. When the head unit 24 moves in the Y direction over a long distance, the head unit 24 is moved at a high speed by driving by the hollow motor 82 of the Y direction driving device 27 and driving by the sub driving motor 83.

The characteristics of the second and third electronic component transfer units 22 and 23 that allow the head units 24 and 24 to move in opposition will be described with reference to FIG.
While the electronic component 11 is being mounted on the printed wiring board 4 at the most downstream position by the third electronic component transfer unit 23, the second electronic component transfer unit 22 picks up the electronic component 11 of the electronic component supply unit 8a by the suction nozzle. Adsorbed at 36. The second electronic component transfer unit 22 can be brought close to the third electronic component transfer unit 23 to a position where the component recognition devices 35 do not collide with each other.

  As a result, the head unit 24 of the second electronic component transfer unit 22 is moved to the mounting position of the printed wiring board 4 at the most downstream position, which is directly below the head unit 24 of the third electronic component transfer unit 23. It can be closer in the X direction. That is, while one of the pair of electronic component transfer units is being mounted, the other electronic component transfer unit has an electronic component in a wide range (L) in the X direction from the center of the printed wiring board 4 to be mounted. The electronic component transfer unit can be picked up and the electronic component in the wide X direction (L) of the other electronic component transfer unit is picked up, so there is no need to stop mounting one electronic component transfer unit, improving the mounting efficiency it can.

  On the other hand, when the printed wiring board 4 is large, the electronic component 11 is simultaneously mounted on the single printed wiring board 4 by the second and third electronic component transfer units 22 and 23 as shown in FIG. . In this case, two large printed wiring boards 4 are held on the transport device 3, and electronic components are mounted on the other printed wiring board 4 by the first electronic component transfer unit 21. When this mounting form is adopted, the electronic component 11 can be mounted on both printed wiring boards 4 by the second electronic component transfer unit 22.

  The head unit 24 of the second electronic component transfer unit 22 is provided at a position facing the third electronic component transfer unit 23 in the support member 32. The head unit 24 of the third electronic component transfer unit 23 is provided at a position facing the second electronic component transfer unit 22 in the support member 32.

  That is, when the electronic component 11 is mounted on one printed wiring board 4 by the second and third electronic component transfer units 22 and 23, the electronic component transfer units 22 and 23 are brought close to each other. As shown in FIG. 10, the head units 24 of the second and third electronic component transfer units 22 and 23 are positioned adjacent to each other in the X direction.

  In this case, the two support members 32 and 32 that support these head units 24 so as to be movable in the Y direction are positioned on both sides in the X direction with respect to both head units 24 and 24 so as to sandwich both head units 24 therebetween. Will come to do.

  For this reason, since the support member 32 is not positioned between the two head units 24, the support member 32 does not narrow the mountable range of the other electronic component transfer unit. As a result, according to the surface mounter 1 according to this embodiment, one electronic component transfer unit does not wait for the movement of the other electronic component transfer unit, and the mounting efficiency can be improved.

  Further, even when the electronic component 11 is mounted on one printed wiring board 4 by the second and third electronic component transfer units 22 and 23, the electronic component 11 is being mounted by one electronic component transfer unit. Even if the electronic component 11 is adsorbed by the other electronic component transfer unit and this is alternately performed, the mounting efficiency can be improved. In this case, the electronic component located near the X direction can be attracted to the counterpart head unit 24 being mounted. As a result, the electronic component 11 of the electronic component supply unit 8a in a wide range in the X direction can be attached to the printed wiring board. 4 can be implemented.

  Moreover, since each X direction moving member 25 of the 1st-3rd electronic component transfer units 21-23 moves to the X direction on the base 2, it moves in the state where support was stable. For this reason, the X-direction moving member 25 is different from a member that is hung on the guide rail like the support member of the conventional surface mounter, and the suction nozzle 36 vibrates even if it moves at a high speed. There is no such thing.

  The surface mounter 1 according to this embodiment includes a first electronic component transfer unit at a position adjacent to the second and third electronic component transfer units 22 and 23 in which the head unit 24 faces each other in the X direction. 21 is provided. The head unit 24 of the first electronic component transfer unit 21 is provided on the side of the support member 32 adjacent to the second and third electronic component transfer units 22 and 23 so as to be movable in the Y direction. .

  Therefore, when the second and third electronic component transfer units 22 and 23 are mounting the electronic component 11 on the printed wiring board 7, the first electronic component transfer units 22 and 23 are transferred to the electronic component transfer units 22 and 23. The head unit 24 of the mounting unit 21 can be approached. Therefore, the range in which the first electronic component transfer unit 21 can take out the electronic component 11 from the electronic component supply device 9 is the components of the second and third electronic component transfer units 22 and 23 in the X direction. It can be expanded to overlap the extraction area. Therefore, in the first electronic component transfer unit 21, mounting can be performed using more parts feeders 8.

  Further, according to this embodiment, the second and third electronic component transfer units 22 and 23 and the first electronic component transfer unit 21 mount the electronic components 11 on the different printed wiring boards 4 respectively. When adopting the configuration, the interval between the two printed wiring boards 4 and 4 can be reduced. As a result, the surface mounter 1 with a reduced size could be manufactured.

  In the surface mounter 1 according to this embodiment, the X-direction moving member 25 moves along the X-direction guide rail 33 when the hollow motor 34 provided on the X-direction moving member 25 rotates the ball nut 42. . The X-direction drive device 26 having the hollow motor 34 can increase the rotation speed of the hollow motor 34 as compared with a general ball screw mechanism that moves the ball nut by rotating the X-direction ball screw shaft.

  This is because when the ball screw shaft is rotated at a high speed, the rotation speed is restricted in order to prevent the occurrence of the so-called “resonance phenomenon of the shaft due to rotational vibration force”, but this restriction is released by rotating the ball nut 42. Because it can. The resonance phenomenon of the shaft due to the rotational vibration force is a phenomenon in which the ball screw shaft rotating at high speed rotates while being bent so that the amplitude becomes maximum at the central portion, for example.

In general, since the ball screw shaft has a larger inertia than the ball nut when it is stopped, there is a limit to increasing the rotation speed in order to stop the ball nut with high accuracy. Are also subject to rotational speed constraints.
Therefore, according to this embodiment, the X-direction moving member 25 can be moved at a higher speed than when driven by a ball screw mechanism configured to rotate the ball screw shaft, and the mounting efficiency can be further improved. Can do.

In the surface mounter 1 according to this embodiment, the head unit 24 can also be driven by the Y-direction drive device 27 having the hollow motor 34. As described above, the Y-direction drive device 27 can increase the rotation speed of the motor as compared with the drive device configured to rotate the ball screw shaft.
Therefore, according to this embodiment, the head unit 24 can be moved at high speed, and the mounting efficiency can be further improved.

  In the surface mounter 1 according to this embodiment, the maintenance of the suction head 55 provided in the head unit 24 is performed with the head unit 24 disassembled as shown in FIG. At this time, the bolts 58 and 64 of the connecting members 57 and 63 are removed to separate the second support plate 54 from the first support plate 53, and the second frame 62 is separated from the first frame 61.

  The first support plate 53 and the second support plate 54 are movably supported by the Y-direction guide rail 51 via sliders 52, respectively. Therefore, by moving the second support plate 54 away from the first support plate 53, the four head units 24 on the first frame 61 side and the second frame 62 side are moved. The space between the four head units 24 can be widely opened.

  Maintenance of each suction head 55 can be performed in this wide space by the operator M extending his / her hand from the front side of the apparatus or the rear side of the apparatus as shown in FIG. At this time, since there are only the X-direction guide rail 33 and the X-direction ball screw shaft 41 on the base 2 between the worker M and the head unit 24, other parts do not get in the way.

The second Y-direction guide rail 101 is formed to have substantially the same length as the Y-direction guide rail 51 provided on the support member 32. That is, the movement range of the component recognition device 35 in the Y direction is the same as that of the head unit 24.

  The component recognition device 35 moves in the Y direction by driving of the driving device 102 located between the pair of second Y direction guide rails 101, 101. The drive device 102 is of a ball screw type, and although not shown, a ball screw shaft extending in parallel with the second Y-direction guide rail 101, a motor for rotating the ball screw shaft, and the ball A ball nut or the like screwed onto the screw shaft is used.

In this embodiment, the end surface A (see FIG. 14) located on the side opposite to the support member 32 in the head unit 24 protrudes in the X direction from the end surface B of the leg member 31 in the X direction. By adopting this configuration, the head unit 24 can be brought closer to another component transfer unit, so that the range in which the electronic component 11 can be taken out by the head unit 24 can be further expanded in the X direction.

  In this embodiment, in order to take an image of the electronic component 11 sucked by the suction nozzle 36, the component recognition device 35 located closest to the Y direction is moved. That is, in the second and third electronic component transfer units 22 and 23 configured so that the head unit 24 faces each other, of the pair of component recognition devices 35 and 35 of the electronic component transfer unit being mounted, At least the component recognition device 35 on the side close to the Y direction is moved to the head unit of the electronic component transfer unit during the suction operation, or among the pair of component recognition devices 35, 35 of the electronic component transfer unit during the suction operation, The component recognition device 35 on the side far from the Y direction is moved from the head unit during the suction operation.

  In this embodiment, the upper surface of the component recognition device 35, the upper surface of the electronic component supply unit 8a of the parts feeder 8, and the upper surface of the printed wiring board 4 are positioned at substantially the same height. Therefore, when the suction head 55 is moved from above the parts feeder 8 to above the printed wiring board 4 through the parts recognition device 35 or from above the printed wiring board 4 to above the parts feeder 8, the suction head 55 is moved. The lifting distance of 55 can be reduced, and the mounting efficiency can be improved. The component recognition device 35 can also be configured by mounting the camera 37 on the base 2 in a state of being directed upward without using the reflecting mirror 38. By adopting this configuration, the vertical length of the leg member 31 can be shortened, so that the X-direction moving member 25 can be reduced in weight, and the transfer speed of the electronic component 11 in the X direction can be improved.

  Thereby, the electronic component transfer unit in the suction operation can suck an electronic component in a range (L) wider than the X direction from the central portion of the printed wiring board 4 to be mounted, and as a result, the other There is no need to stop mounting the electronic component transfer unit, and the mounting efficiency can be improved.
