[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings as modes for carrying out the present invention.

[0010] FIG. 1 shows an electronic component mounting system 10. The electronic component mounting system 10 is composed of one system base 12 and one working unit 16 disposed on the system base 12. As shown in FIG. 2, the working unit 16 is equipped with two substrate-related operation machines 18. The two substrate-related operation machines 18 are disposed adjacent to each other, and the direction in which the two substrate-related operation machines 18 are aligned is referred to as the X-axis direction, and the horizontal direction perpendicular to that direction is referred to as the Y-axis direction. Note that FIG. 2 is a plan view showing the interior of the working unit 16 as viewed from above.

[0011] The two substrate-related performing machines 18 have substantially the same structure, and each substrate-related performing machine 18 mainly comprises a performing machine main body 20, a transport device 22, a moving device 24, a mounting head 26, and a supply device 28. The performing machine main body 20 is composed of a frame 32 and a beam 34 (see FIG. 1) suspended above the frame 32.

[0012] The transfer device 22 includes two conveyor devices 40, 42. The two conveyor devices 40, 42 are arranged on the frame 32 so as to be parallel to each other and extend in the X-axis direction. Each of the two conveyor devices 40, 42 is driven by an electromagnetic motor (not shown) to transfer a circuit board supported by the respective conveyor device 40, 42 in the X-axis direction. The circuit board is fixedly held at a predetermined position by a board holding device (not shown).

[0013] The moving device 24 is an XY robot type moving device. The moving device 24 is equipped with an electromagnetic motor (not shown) that slides the slider 50 in the X-axis direction, and another electromagnetic motor (not shown) that slides the slider 50 in the Y-axis direction. The mounting head 26 is attached to the slider 50, and the mounting head 26 can be moved to any position on the frame 32 by the operation of the two electromagnetic motors.

[0014] The placement head 26 places electronic components on the circuit board. The placement head 26 has a suction nozzle 60 provided on its bottom surface. The suction nozzle 60 is connected to a positive / negative pressure supply device (not shown) via negative pressure air and positive pressure air passages. The suction nozzle 60 sucks and holds electronic components using negative pressure, and releases the held electronic components using positive pressure. The placement head 26 also has a nozzle lifting device (not shown) that raises and lowers the suction nozzle 60. The nozzle lifting device allows the placement head 26 to change the vertical position of the electronic component it is holding.

[0015] The supply device 28 is a feeder-type supply device and, as shown in FIG. 3 , includes a carriage 70, a feeder holder 72, and a tape feeder 74. The carriage 70 has multiple wheels 76 on its underside, allowing an operator to push the carriage 70 to move it to any position. A feeder holder 72 is fixed to the carriage 70. The feeder holder 72 is composed of a generally plate-shaped slide portion 78 fixed to the upper surface of the carriage 70 and an upright surface portion 80 erected at the end of the slide portion 78. A plurality of linearly extending slide grooves 82 are formed on the upper surface of the slide portion 78. A rail 84 is attached to the lower edge of the tape feeder 74. By fitting the rail 84 into the slide groove 82, the tape feeder 74 can be slid on the upper surface of the slide portion 78 in a direction toward or away from the upright surface portion 80.

[0016] Further, female connectors 86 are provided on the upright surface portion 80 in correspondence with the plurality of slide grooves 82. Meanwhile, male connectors 88 are provided on the side wall surface of the tape feeder 74. When the tape feeder 74 is fitted into the slide grooves 82 and pushed toward the upright surface portion 80, the male connectors 88 are connected to the female connectors 86. As a result, the tape feeder 74 is mounted on the feeder holder 72 while electrically connected to the feeder holder 72. The tape feeder 74 also accommodates taped components in a wound state. The taped components are electronic components that have been taped. The tape feeder 74 feeds the taped components using a feeding device (not shown). As a result, the tape feeder 74 feeds the taped components to the supply position. Note that not only the tape feeder 74 but also various other feeders such as bowl feeders and stick feeders can be mounted on the feeder holder 72.

[0017] Furthermore, in the supply device 28, a female connector 90 is also provided on the side opposite to the side on which the female connector 86 is provided on the upright surface 80 of the feeder holder 72. Meanwhile, as shown in FIG. 4 , the working unit 16 of the electronic component mounting system 10 has a male connector 92 provided at its end in the Y-axis direction. Then, the female connector 90 of the supply device 28 is connected to the male connector 92 of the working unit 16, thereby mounting the supply device 28 to the working unit 16 in an electrically connected state. More specifically, the operator operates the carriage 70 of the supply device 28 to bring the female connector 90 of the supply device 28 close to the male connector 92 of the working unit 16 in the Y direction. Then, the operator pushes the supply device 28 toward the working unit 16, thereby mounting the female connector 90 of the supply device 28 to the male connector 92 of the working unit 16. This allows the supply device 28 to be mounted to the working unit 16 in an electrically connected state. In the following drawings, the supply device 28 is shown schematically as shown in FIG. 4 and the like.

[0018] The supply device 28 is also provided with a restriction arm 100 that extends toward the working unit 16. The restriction arm 100 enters the interior of the working unit 16 when the supply device 28 is attached to the working unit 16. The tip of the restriction arm 100 is bent into a generally L-shape. A stopper 102 is disposed inside the working unit 16 at a position opposite the L-shaped bent tip of the restriction arm 100 in the Y-axis direction. This restricts the movement of the supply device 28 when attached to the working unit 16. In other words, when the supply device 28 attached to the working unit 16 moves in a direction away from the working unit 16, the L-shaped bent tip of the restriction arm 100 comes into contact with the stopper 102, restricting the movement of the supply device 28 in a direction away from the working unit 16. When the supply device 28 is attached to the working unit 16, the distance between the L-shaped bent tip of the restriction arm 100 and the stopper 102 is L. Therefore, when supply device 28 attached to working unit 16 moves a distance equivalent to L in a direction away from working unit 16, the movement of supply device 28 is restricted by regulating arm 100 and stopper 102. In other words, when supply device 28 attached to working unit 16 moves a predetermined amount L from working unit 16, the movement of supply device 28 is restricted by regulating arm 100 and stopper 102.

[0019] The stopper 102 disposed on the working unit 16 rotates around a shaft 104. Therefore, by rotating the stopper 102, the supply device 28 can be removed from or attached to the working unit 16 without interference between the regulating arm 100 and the stopper 102.

[0020] By attaching the supply device 28 to the working unit 16 in this manner, as shown in FIG. 2 , the supply device 28 is disposed at the end of the substrate-related operation machine 18 in the Y-axis direction. The substrate-related operation machine 18 thus configured performs an operation of mounting electronic components on a circuit board held by the transport device 22. Specifically, the transport device 22 transports the circuit board to a work position and securely holds the circuit board at that position. Furthermore, in the supply device 28, the tape feeder 74 feeds out taped components and supplies the electronic components at the supply position. The placement head 26 then moves to above the electronic component supply position by operation of the movement device 24, and sucks and holds the electronic components with the suction nozzle 60. The placement head 26 then moves to above the circuit board by operation of the movement device 24, and mounts the held electronic components onto the circuit board. In this manner, the substrate-related operation machine 18 performs an operation of mounting electronic components.

[0021] 1, in electronic component mounting system 10, a pair of rails 110 are disposed on the upper surface of system base 12 so as to extend in the Y-axis direction. Working unit 16 is disposed on pair of rails 110 and is slidable relative to system base 12 in the direction in which rails 110 extend. In other words, working unit 16 is disposed on system base 12 so as to be slidable in the Y-axis direction.

[0022] However, the working unit 16 can only slide in one direction in the Y-axis direction from a state where it is positioned directly above the system base 12, but a stopper (not shown) prevents it from sliding in the other direction in the Y-axis direction. Note that one direction in the Y-axis direction, i.e., the direction in which the working unit 16 can slide, is the direction toward the side where the supply device 28 of the working unit 16 is attached. Therefore, the working unit 16 can slide in the Y-axis direction from the position shown in Figure 4 as shown in Figure 5. Note that one direction in the Y-axis direction is referred to as the forward direction, and the other direction in the Y-axis direction is referred to as the rearward direction.

[0023] The forward sliding of the working unit 16 is restricted by a stopper (see FIG. 4) 112. More specifically, a generally L-shaped bracket 114 is disposed on the underside of the working unit 16. A stopper 112 is disposed on the system base 12 on the front side of the bracket 114 so as to face the bracket 114 in the Y-axis direction. Therefore, when the worker slides the working unit 16 forward, as shown in FIG. 5, the bracket 114 of the working unit 16 comes into contact with the stopper 112 of the system base 12, restricting the forward sliding of the working unit 16.

[0024] In this way, the worker slides the working unit 16 forward to perform maintenance on the interior of the working unit 16. However, if the worker slides the working unit 16 forward with force, the female connector 90 of the supply device 28 may become disengaged from the male connector 92 of the working unit 16. More specifically, when the worker slides the working unit 16 from the position shown in FIG. 4 to the position shown in FIG. 5, the supply device 28 moves forward together with the working unit 16. However, when the working unit 16 slides to the position shown in FIG. 5, the bracket 114 of the working unit 16 comes into contact with the stopper 112 of the system base 12, thereby restricting the forward sliding of the working unit 16. At this time, as shown in FIG. 6, the forward sliding of the working unit 16 stops, but the supply device 28 moves forward due to inertia, causing the female connector 90 of the supply device 28 to become disengaged from the male connector 92 of the working unit 16. However, as described above, forward movement of the supply device 28, that is, movement in the direction away from the working unit 16, is restricted by the restriction arm 100 and the stopper 102. In other words, when the supply device 28 attached to the working unit 16 moves forward a distance equivalent to L, the movement of the supply device 28 is restricted by the restriction arm 100 and the stopper 102. Therefore, the distance between the female connector 90 that has come off the male connector 92 and the male connector 92 is L.

[0025] In this way, even if the female connector 90 of the supply device 28 comes off the male connector 92 of the working unit 16 when the worker slides the working unit 16 forward, the forward movement of the supply device 28 is restricted by the restricting arm 100 and the stopper 102. However, if the female connector 90 of the supply device 28 comes off the male connector 92 of the working unit 16, it is necessary to reconnect the female connector 90 of the supply device 28 to the male connector 92 of the working unit 16, which is time-consuming for the worker. In consideration of this, a female connector 120 is provided on the supply device 28 and a male connector 122 is provided on the working unit 16, as shown in FIG. 7 .

[0026] More specifically, the female connector 120 is generally block-shaped, and as shown in Fig. 8, six insertion holes 130 are formed in a 2 x 3 array at the center of one surface of the female connector 120. Fig. 8 shows a plan view of the surface of the female connector 120 on which the insertion holes 130 are formed, and a cross-sectional view taken along line AA. The female connector 120 also has two positioning holes 132 formed in two of its four corners, diagonally opposite the six insertion holes 130. The female connector 120 having this structure is fixed to the supply device 28 on the surface opposite to the surface on which the insertion holes 130 and positioning holes 132 are formed.

[0027] The male connector 122 is also generally block-shaped, and as shown in FIG. 9, the male connector 122 is slidably attached to the working unit 16 by four shafts 138. Six connector pins 140 are arranged in a 2×3 row and erected in the center of one surface of the male connector 122. The erected positions of the six connector pins 140 correspond to the formation positions of the six insertion holes 130 of the female connector 120, and the outer dimensions of the connector pins 140 are slightly smaller than the inner dimensions of the insertion holes 130. FIG. 9 shows a plan view of the surface of the male connector 122 on which the connector pins 140 are erected, and a cross-sectional view taken along line BB. The male connector 122 also has two positioning pins 142 erected at two diagonal positions on either side of the six connector pins 140. The positions at which the two positioning pins 142 are erected correspond to the positions at which the two positioning holes 132 of the female connector 120 are formed, and the outer dimensions of the positioning pins 142 are slightly smaller than the inner dimensions of the positioning holes 132 .

[0028] Four through holes 146 are formed at the four corners of male connector 122 to connect the surface of male connector 122 on which connector pins 140 and the like are erected with the surface opposite that surface. The inner diameter of through holes 146 is slightly larger than the outer diameter of shafts 138, and four shafts 138 are inserted into the four through holes 146. The ends of the four shafts 138 extending from the surface of male connector 122 opposite the surface on which connector pins 140 and the like are erected are fixed to working unit 16. In this way, male connector 122 is disposed in working unit 16 by four shafts 138 and is slidable along the direction in which shafts 138 extend. Note that shafts 138 are disposed to extend in the Y-axis direction, so male connector 122 slides along the Y-axis direction.

[0029] Furthermore, a head 148 having an outer diameter larger than the inner diameter of the through-hole 146 is formed on the end of the shaft 138 opposite the end that is fixed to the working unit 16. A coil spring 150 is fitted onto the outer circumferential surface of the shaft 138, between the working unit 16 and the male connector 122. As a result, the male connector 122 is biased in a direction away from the working unit 16 by the elastic force of the coil spring 150. The male connector 122, which is slidably disposed on the working unit 16, is connected to the working unit 16 via multiple cables 152 to ensure electrical connection with the working unit 16.

[0030] In this way, the female connector 120 is provided on the supply device 28, and the male connector 122 is provided on the working unit 16. Then, the female connector 120 of the supply device 28 is connected to the male connector 122 of the working unit 16, whereby the supply device 28 is attached to the working unit 16 while being electrically connected to the working unit 16. More specifically, the worker operates the carriage 70 of the supply device 28 to bring the female connector 120 of the supply device 28 close to the male connector 122 of the working unit 16 along the Y direction. Then, the worker pushes the supply device 28 toward the working unit 16, whereby the female connector 120 of the supply device 28 is connected to the male connector 122 of the working unit 16, as shown in FIG. 7 . At this time, the six connector pins 140 of the male connector 122 are inserted into the six insertion holes 130 of the female connector 120, and the two positioning pins 142 of the male connector 122 are inserted into the two positioning holes 132 of the female connector 120. As a result, the supply device 28 is attached to the working unit 16 in a state in which the supply device 28 is electrically connected to the working unit 16 .

[0031] When the female connector 120 of the supply device 28 is connected to the male connector 122 of the working unit 16, the female connector 120 pushes the male connector 122 toward the working unit 16, causing the male connector 122 to approach the working unit 16 against the elastic force of the coil spring 150. At this time, the coil spring 150 urges the male connector 122 toward the female connector 120. In other words, when the female connector 120 is connected to the male connector 122, the coil spring 150 urges the male connector 122 toward the female connector 120. As a result, the elastic force of the coil spring 150 functions as a force that connects the female connector 120 and the male connector 122, making it easier to connect the female connector 120 and the male connector 122.

[0032] Furthermore, when the female connector 120 is connected to the male connector 122, the male connector 122 approaches the working unit 16 along the shaft 138, and the end of the shaft 138 to which the head 148 is fixed extends from the through-hole 146 of the male connector 122 toward the supply device 28. At this time, the extension amount of the shaft 138 from the male connector 122 is S. In other words, when the female connector 120 is connected to the male connector 122, the length of the shaft 138 between the end face of the male connector 122 on the supply device 28 side and the head 148 is S. Note that the extension amount S of the shaft 138 from the male connector 122 is longer than the movement amount L of the supply device 28 before the movement of the supply device 28 is restricted by the above-described restriction arm 100 and stopper 102.

[0033] With female connector 120 connected to male connector 122 and feeder 28 attached to working unit 16, when the worker slides working unit 16 forward as shown in FIG. 10, stopper 112 and bracket 114 restrict the forward sliding of working unit 16. At this time, the forward sliding of working unit 16 is stopped, but feeder 28 moves forward due to inertia. In such a case, in the conventional electronic component mounting system 10, as shown in FIG. 6, female connector 90 of feeder 28 becomes disengaged from male connector 92 of working unit 16. However, by providing male connector 122 on working unit 16, as shown in FIG. 11, even if feeder 28 moves forward due to inertia while the forward sliding of working unit 16 is stopped, male connector 122 slides, maintaining the connection between female connector 120 and male connector 122. In other words, when the supply device 28 moves in a direction away from the working unit 16 while the working unit 16 is stopped, the female connector 120 also moves away from the working unit 16 together with the supply device 28, but the male connector 122 connected to the female connector 120 follows the female connector 120 and slides in a direction away from the working unit 16. This makes it possible to maintain the connection between the female connector 120 and the male connector 122, even when the supply device 28 moves in a direction away from the working unit 16 while the working unit 16 is stopped.

[0034] 7, the extension amount of the shaft 138 from the male connector 122 is S. That is, the male connector 122 in the state shown in FIG. 7 can slide a maximum distance corresponding to S in the direction away from the working unit 16. That is, the maximum sliding amount of the male connector 122 in the state shown in FIG. 7 in the direction away from the working unit 16 is S. On the other hand, as described above, when the supply device 28 attached to the working unit 16 moves a distance corresponding to L in the direction away from the working unit 16, the movement of the supply device 28 is restricted by the restriction arm 100 and the stopper 102. That is, the movement amount of the supply device 28 before the movement of the supply device 28 is restricted by the restriction arm 100 and the stopper 102 is L. The maximum sliding amount S of the male connector 122 is longer than the movement amount L of the supply device 28. Therefore, before the male connector 122 slides a distance corresponding to the maximum sliding amount S, the forward movement of the supply device 28 is restricted by the restriction arm 100 and the stopper 102. In other words, when the supply device 28 moves in a direction away from the working unit 16, the male connector 122 slides following the female connector 120 until the supply device 28 is stopped by the restriction arm 100 and the stopper 102. This makes it possible to reliably maintain the connection between the female connector 120 and the male connector 122 until the movement of the supply device 28 in the direction away from the working unit 16 stops.

[0035] Furthermore, when male connector 122 slides along female connector 120, male connector 122 is biased toward female connector 120 by coil spring 150. In other words, the elastic force of coil spring 150 functions as a force that causes female connector 120 to follow male connector 122. This makes it easier for male connector 122 to slide along female connector 120, and the connection between female connector 120 and male connector 122 can be properly maintained.

[0036] In the above embodiment, the electronic component mounting system 10 is an example of a substrate-related operating machine. The operating unit 16 is an example of an operating machine body. The supply device 28 is an example of an operating device. The wheels 76 are an example of wheels. The stopper 102 is an example of a stopper. The female connector 120 is an example of a female connector. The male connector 122 is an example of a male connector. The coil spring 150 is an example of an elastic body.

[0037] As described above, the present embodiment has the following advantages.

[0038] In electronic component mounting system 10, male connector 122 is provided on working unit 16, and female connector 120 is provided on supply device 28. When an operator moves supply device 28 in the Y-axis direction so that female connector 120 approaches male connector 122, female connector 120 connects with male connector 122, and supply device 28 is attached to working unit 16. Furthermore, male connector 122 provided on working unit 16 is slidable in the Y-axis direction relative to working unit 16. As a result, even if supply device 28 moves in a direction away from working unit 16, male connector 122 slides following female connector 120, so that the connection between female connector 120 and male connector 122 can be maintained.

[0039] Furthermore, a coil spring 150 is fitted onto the shaft 138 of the male connector 122 for attaching the male connector 122 to the working unit 16. The coil spring 150 biases the male connector 122 toward the female connector 120 when the female connector 120 and the male connector 122 are connected. As a result, when the female connector 120 is connected to the male connector 122, the elastic force of the coil spring 150 functions as a force that connects the female connector 120 and the male connector 122, making it easier to connect the female connector 120 and the male connector 122. Furthermore, when the supply device 28 moves in a direction away from the working unit 16, the elastic force of the coil spring 150 functions as a force that causes the female connector 120 to follow the male connector 122, thereby allowing the connection between the female connector 120 and the male connector 122 to be properly maintained.

[0040] Furthermore, when supply device 28 moves a distance equivalent to L in a direction away from working unit 16, the movement of supply device 28 is restricted by restriction arm 100 and stopper 102. Furthermore, the maximum slide amount S of male connector 122 is longer than the movement amount L of supply device 28. As a result, male connector 122 follows female connector 120 until the movement of supply device 28 in a direction away from working unit 16 is restricted, thereby making it possible to reliably maintain the connection between female connector 120 and male connector 122.

[0041] Furthermore, the supply device 28 can be moved to any position by a cart 70 having wheels 76. By providing a slidable male connector 122 on the working unit 16 to which the easily movable supply device 28 is attached, it is possible to maintain an appropriate connection between the female connector 90 and the male connector 122.

[0042] Furthermore, when the supply device 28 moves forward along the Y-axis direction from the state where it is attached to the working unit 16, the male connector 122 slides in the Y-axis direction, thereby maintaining the connection between the female connector 120 and the male connector 122. This makes it possible to prevent the female connector 120 from coming off the male connector 122.

[0043] The present invention is not limited to the above-described embodiment, and can be embodied in various forms with various modifications and improvements based on the knowledge of those skilled in the art. Specifically, for example, in the above-described embodiment, the male connector 122 is slidably disposed in the working unit 16, but the female connector 120 may be slidably disposed in the supply device 28. Also, while the male connector 122 is disposed in the working unit 16 and the female connector 120 is disposed in the supply device 28, the female connector 120 may be disposed in the working unit 16 and the male connector 122 in the supply device 28.

[0044] Furthermore, in the above embodiment, the supply device 28 that supplies components by tape feeder 74 is used as the operating device attached to the operating unit 16, but a supply device that supplies components by tray or the like may also be used. Also, the operating device is not limited to a supply device, and various devices can be used as the operating device.

[0045] Furthermore, as described above, the supply device 28 having wheels 76 is used as the working device attached to the working unit 16, but a working device without wheels 76 may also be used. For example, a tape feeder or the like that is directly attached to the working unit 16 can be used as the working device.

[0046] Furthermore, in the above embodiment, the coil spring 150 is used as the elastic body that biases the male connector 122 toward the female connector 120, but various elastic bodies such as rubber and torsion springs can also be used. On the other hand, the male connector 122 may be disposed on the working unit 16 by the shaft 138 without using an elastic body. In other words, if the male connector 122 is slidable, the male connector 122 can be made to follow the female connector 120, and therefore the connection between the female connector 120 and the male connector 122 can be maintained without using an elastic body.

[0047] Furthermore, in the above embodiment, the present invention is applied to an electronic component mounting system 10 that performs the mounting work of electronic components on a circuit board, but the present invention can also be applied to various other substrate-related work machines, such as a printing work machine that performs the printing work of fluid on a circuit board, or an inspection work machine that performs the inspection work of a circuit board.
