JP 2012-84718 A

  However, as described above, in the conventional loose component supply apparatus, every time the component is picked up by the mounting head, the next component is transported to the suction position. Time has occurred. Here, if the component mounting operation is performed by a mounting head having only one suction nozzle for extracting the component, the mounting head picks up the component, and then mounts the component on the board and returns. In addition, the effect is small because the next part is considered to arrive at the suction position. However, in order to improve the efficiency of component mounting work, the mounting head is generally provided with a plurality of suction nozzles. In such a case, after one suction nozzle takes out the component, the mounting head Even though the next suction nozzle is ready to take out a part on the side, a waiting time occurs because the part has not arrived at the suction position on the part supply apparatus side.

You may make it comprise so that it may carry out alignment conveyance toward the other end of the said groove part. In this way, in the component supply unit, a plurality of components are aligned in the substrate transport direction in a state where the longitudinal direction of the components is orthogonal to the substrate transport direction, so that the arrangement pitch of the components can be reduced. As a result, the length of the component supply unit in the board conveyance direction can be shortened, and the moving distance when the mounting head continuously takes out components can be shortened depending on the type of the mounting head.

The groove may extend to a position where the extending direction of the groove portion is the substrate transport direction. In this way, when one end of the groove portion of the component supply portion communicates with the component passage, the extending direction of the groove portion is the same as the conveying direction of the component in the component passage, so that the component can be quickly sent from the component passage to the component supply portion. Can do. Further, when the mounting head picks up the component, if the component supply unit is rotated so that the direction in which the groove extends is the substrate transport direction, the mounting head movement stroke in the direction perpendicular to the substrate transport direction can be reduced. it can.

In this way, the component mounting apparatus acquires the arrangement pitch information of the components stored in the storage means of the bulk component supply device, so that the movement pitch of the mounting head when the mounting head picks up the component is input to the operator. Regardless of the operation, it can be set automatically. In particular, in the bulk component supply device, since it is often designed exclusively for each type of component, it is significant to store the arrangement pitch for each component supply device.

It is a positional relationship. Accordingly, the reel component supply device 56 can be provided in the bulk component supply device 100 in the vicinity of the side surface of the bowl 111. The groove width of the groove 132 is substantially the same as the length in the longitudinal direction of the component and is larger than the length of the component. Further, the component supply unit 130 includes a first detection sensor 133 that detects a component located at the end on the introduction port 131 side, and a second detection sensor that detects a component located on the end opposite to the introduction port 131. 134.

The control device 60 is connected to the transport unit 18, the sampling unit 21, the parts camera 54, the reel component supply device 56, the bulk component supply device 100 and the like so as to be capable of bidirectional communication. Each slider 26 and 30 is equipped with a position sensor (not shown), and the control device 60 controls the drive motor of each slider 26 and 30 while inputting position information from these position sensors.

  Next, operations of the component mounting apparatus 10 and the bulk component supply apparatus 100 of the present embodiment configured as described above will be described. When the production of the substrate S by the component mounting device 10 is started, the bulk component supply device 100 starts a component supply operation. When the component supply operation is started, the vibration unit 112 vibrates the bowl 111. Due to this vibration, the parts accommodated in the bowl 111 in a stacked state are conveyed toward the parts path 120 while being aligned along the first conveyance path 113. At this time, the components are aligned so that the longitudinal direction of the component is parallel to the traveling direction of the component. Thereafter, as shown in FIG. 5, the component is transferred from the first conveyance path 113 to the second conveyance path 121 of the component path 120, and the component is moved on the second conveyance path 121 by the component path conveyance means (not shown). The direction is aligned and conveyed to the component supply unit 130 in a direction perpendicular to the substrate conveyance direction. Note that when the first detection sensor 133 detects that the component supplying unit conveying means component has arrived at the end of the groove 132 of the component supplying unit 130 on the inlet 131 side, the conveying operation is started. The components are conveyed toward the end of the groove 132 opposite to the inlet 131 by the component supply unit conveying means. At this time, the components are conveyed in a posture in which the longitudinal direction of the component is orthogonal to the substrate conveying direction. The As shown in FIG. 6, when eight parts are stocked up to the end of the groove 132 on the introduction port 131 side, the first detection sensor 133 and the second detection sensor 134 are kept on, so that such a state is detected. Then, the conveying operation of the component supply unit conveying means is stopped, and the component is taken out by the mounting head 24. When the component is taken out by the mounting head 24, the component mounting apparatus 10 acquires and uses the arrangement pitch information and the component extraction reference position information from the storage unit of the bulk component supply device 100. The extraction reference position information is information indicating the position of the first component to be extracted. Based on the acquired extraction reference position information, the mounting head 24 is moved to the position of the component located at the end of the groove portion 132 on the introduction port 131 side, and the component is extracted by the first nozzle 40. Next, based on the arrangement pitch information, the mounting head 24 is moved by the arrangement pitch, and the component is taken out by the second nozzle 40. Similarly, when the components have been taken out to the eighth nozzle 40, the mounting head 24 is moved onto the substrate S, and the components are mounted on the substrate S. While the mounting head 24 mounts components on the substrate S, the bulk component supply apparatus 100 performs the same operation as described above, and stocks eight components in the component supply unit 130.

  According to the bulk component supply apparatus 100 of the present embodiment described above, in the component supply unit 130, a plurality of components conveyed from the component passage 120 are pre-aligned and stocked, so a plurality of components are taken out at short intervals. The waiting time of the mounting head 24 at the time can be reduced, and the work efficiency of the component mounting work can be improved. In addition, since the components are stocked in the component supply unit 130 using the time during which the mounting head 24 performs the component mounting operation on the substrate S, the waiting time of the mounting head 24 can be reduced. Furthermore, since a plurality of components are aligned in the conveyance direction of the substrate S, the movement stroke of the mounting head 24 in the direction orthogonal to the substrate conveyance direction can be reduced.

  Further, in the component supply unit 130, the plurality of components are aligned in the substrate transport direction in a state where the longitudinal direction of the components is orthogonal to the substrate transport direction, so that the arrangement pitch of the components can be reduced. Thereby, the length of the component supply unit 130 in the board conveyance direction can be shortened. Further, for example, in the mounting head 24 in which the nozzle 40 extracts components at a fixed position on the mounting head 24 as in the mounting head 24 of the present embodiment, the movement when the mounting head 24 continuously extracts components is performed. The distance can be shortened.

  Further, since the bulk component supply means includes storage means for storing the component arrangement pitch information and the extraction reference position information, the component mounting apparatus 10 acquires the component arrangement pitch information from the bulk component supply device 100, It is possible to automatically set the movement pitch and the extraction reference position of the mounting head 24 when the mounting head 24 picks up the components regardless of the input of the operator. In particular, the bulk component supply device 100 is often designed exclusively for each type of component, so it is significant to store the arrangement pitch for each component supply device. In the bulk component supply apparatus 100, the first component may be taken out at a fixed position regardless of the type of component. In this case, the extraction reference position information is not essential.

  The present invention is not limited to the above-described embodiments, and can be implemented in various aspects. For example, as shown in FIGS. 7 and 8, the component supply unit 130 has a rotation mechanism, and by the rotation mechanism, one end of the groove 132 communicates with the component passage 120, and the extending direction of the groove 132 is orthogonal to the substrate transport direction. You may comprise so that it can rotate to the position used as a direction, and the position where the direction where the groove part 132 is extended becomes a board | substrate conveyance direction. In this embodiment, as shown in FIG. 7, when the first detection sensor 133 and the second detection sensor 134 detect that eight parts are stocked in the component supply unit 130, the conveyance operation of the component supply unit conveyance unit is performed. Is stopped. Thereafter, as shown in FIG. 8, after the component at the end of the component passage 120 and the component at the end of the component supply unit 130 are fixed by the first stopper and the second stopper, the extending direction of the groove 132 is changed by the rotation mechanism. The component supply unit 130 is rotated so as to be in the board conveyance direction. Thereafter, the second stopper is released, and the movement of the part to the left is restricted by restriction means (not shown) so that the part at the end on the second stopper side does not fall off. When this state is reached, the mounting head 24 performs the component removal operation as in the above-described embodiment. According to this embodiment, when one end of the groove portion 132 of the component supply unit 130 communicates with the component passage 120, the extending direction of the groove portion 132 is the same as the conveying direction of the component in the component passage 120. Parts can be sent quickly to the supply unit 130. Further, when the mounting head 24 picks up the component, the component supply unit 130 is rotated so that the extending direction of the groove 132 becomes the substrate transport direction, so that the mounting head 24 moves in a direction perpendicular to the substrate transport direction. Can be reduced.

  In the above-described embodiment, the number of component stocks in the component supply unit 130 is fixed. However, the number of component stocks may be changed according to the size of the component and the number of nozzles of the mounting head 24. Specifically, the configuration may be such that the length of the groove 132 of the component supply unit 130 can be adjusted, and the number of component stocks may be changed. Alternatively, the component supply unit 130 may be replaced, May be changeable.
