DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

[0010] 1 shows an electronic component mounting apparatus (hereinafter sometimes abbreviated as "mounting apparatus") 10. The mounting apparatus 10 has one system base 12 and two electronic component mounting machines (hereinafter sometimes abbreviated as "mounting machines") 16 adjacent to each other on the system base 12. The direction in which the mounting machines 16 are lined up is referred to as the X-axis direction, and the horizontal direction perpendicular to that direction is referred to as the Y-axis direction.

[0011] Each placement machine 16 mainly comprises a placement machine main body 20, a transport device 22, a placement head moving device (hereinafter sometimes abbreviated as "moving device") 24, a placement head 26, and a supply device 28. The placement machine main body 20 is composed of a frame 32 and a beam 34 suspended on the frame 32.

[0012] The transfer device 22 includes two conveyor devices 40, 42. The two conveyor devices 40, 42 are disposed 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 transfers a circuit board supported by each conveyor device 40, 42 in the X-axis direction by an electromagnetic motor (not shown). 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 an 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 is moved to any position on the frame 32 by the operation of the two electromagnetic motors.

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

[0015] Supply device 28 is a feeder type supply device, and is disposed at the front end of frame 32. Supply device 28 has a tape feeder 70. Tape feeder 70 stores taped components, which are tapes containing electronic components, in a wound state. Tape feeder 70 feeds the taped components by the operation of a delivery device (see FIG. 3) 71. Thus, feeder type supply device 28 feeds the taped components to supply electronic components at the supply position.

[0016] 2, taped component 72 is composed of carrier tape 74, electronic components 76, and top cover tape 78. A large number of accommodating recesses 80 and feed holes 82 are formed at equal pitches in carrier tape 74, and electronic components 76 are accommodated in accommodating recesses 80. The accommodating recesses 80 in which electronic components 76 are accommodated are covered by top cover tape 78.

[0017] 3, tape feeder 70 is composed of a reel holder 86 and a feeder body 88, and has tape reel 84 attached. Tape component 72 is wound around reel holder 86, which holds tape reel 84. Tape component 72 is pulled out from tape reel 84 held by reel holder 86, and extends on the upper end surface of feeder body 88. The longitudinal direction of the tape feeder, i.e., the longitudinal direction of slide groove 108 described below, is the tape feed direction.

[0018] A sprocket 90 is built into the feeder body 88 and engages with a feed hole 82 formed in the taped component 72. The sprocket 90 rotates by the operation of the delivery device 71, and the taped component 72 is delivered in a direction away from the tape reel 84 at the upper end surface of the feeder body 88. Furthermore, a peeling device (not shown) peels off the top cover tape 78 from the carrier tape 74 of the taped component 72. As a result, the storage recesses 80 of the taped component 72 are sequentially released at the tip of the upper end surface of the feeder body 88, and the electronic components 76 are taken out of the released storage recesses 80 by the suction nozzle 60.

[0019] The tape feeder 70 is detachably attached to a tape feeder holder 100 fixedly provided at the front end of the frame 32. Specifically, the tape feeder holder 100 is composed of a holder base 102 provided on the upper surface of the frame 32, and a holder side frame 106 erected at the end of the holder base 102 closer to the transport device 22. The holder base 102 is formed with a plurality of slide grooves 108 extending in the Y-axis direction. A rail 110 is attached to the lower edge of the feeder body 88 of the tape feeder 70. By fitting the rail 110 into the slide groove 108, the tape feeder 70 can be slid linearly on the upper surface of the holder base 102 in a direction approaching or separating from the holder side frame 106.

[0020] Furthermore, holding base side frame 106 is provided with a connection terminal 112. Meanwhile, a connector 116 is provided on the side wall surface of tape feeder 70 opposite reel holder 86. Then, the operator fits rail 110 of tape feeder 70 into slide groove 108 of tape feeder holding base 100 and slides tape feeder 70 in a direction approaching holding base side frame 106, whereby connector 116 is connected to connection terminal 112.

[0021] In this manner, the tape feeder 70 is positioned and mounted on the tape feeder holding stand 100. When the worker slides the tape feeder 70 mounted on the tape feeder holding stand 100 in a direction away from the holding stand side frame 106, the connected connector 116 is disconnected from the connection terminal 112 and the tape feeder 70 is removed from the tape feeder holding stand 100. In this manner, the tape feeder 70 is positioned so as to be detachable and mounted on the tape feeder holding stand 100 without the worker using tools. Note that a plurality of slide grooves 108 are formed in the tape feeder holding stand 100 as shown in FIG. 1, and the tape feeder 70 is mounted in any one of the plurality of slide grooves 108.

[0022] Furthermore, the tape feeder 70 mounted on the tape feeder holding stand 100 is electrically connected to the mounting machine 16 by connecting the connector 116 to the connection terminal 112. This allows power to be supplied to the tape feeder 70, and the operation of the delivery device 71, peeling device, etc. is controlled, causing the tape feeder 70 to supply electronic components 76 at the supply position. Note that power is constantly supplied to the tape feeder 70 mounted on the tape feeder holding stand 100, and electronic components 76 are supplied at any timing.

[0023] In the placement machine 16, with the above-mentioned configuration, the placement head 26 performs a placement operation on the circuit board held by the transport device 22. Specifically, the circuit board is transported to the work position and fixedly held at that position. In addition, the tape feeder 70 feeds the taped components 72 and supplies the electronic components 76 at the supply position. Then, the placement head 26 moves to above the supply position of the electronic components 76 and sucks and holds the electronic components 76 with the suction nozzles 60. Next, the placement head 26 moves above the circuit board and places the held electronic components on the circuit board.

[0024] In this manner, in the placement machine 16, the electronic components 76 supplied by the tape feeders 70 are placed on the circuit board. Since multiple types of electronic components are to be placed on the circuit board, multiple tape feeders 70 are attached to the tape feeder holding table 100 of the placement machine 16, and among the multiple tape feeders 70, there are tape feeders that house different types of taped components 72. In this manner, multiple types of electronic components are supplied from the multiple tape feeders 70 attached to the tape feeder holding table 100, and the multiple types of electronic components are placed on the circuit board.

[0025] In this way, a plurality of tape feeders 70 accommodating different types of taped components 72 must be mounted on the tape feeder holding table 100 of the mounting machine 16. For this reason, a tape feeder rack 150, which is separate from the mounting machine 16 shown in Fig. 4, stores a plurality of tape feeders 70 that can be mounted on the tape feeder holding table 100 of the mounting machine 16, and information regarding the types of electronic components accommodated in the tape reels attached to each of the plurality of tape feeders 70 is managed by a control device 170 (see Fig. 5) described below.

[0026] In detail, the tape feeder rack 150 is composed of a rack base 156 and a rack side frame 158 erected on an end of the rack base 156. A plurality of slide grooves 160 are formed in the rack base 156 so as to extend from the end at which the rack side frame 158 is erected toward the opposite end. Each of the plurality of slide grooves 160 has the same shape as the slide groove 108 of the tape feeder holding table 100. For this reason, the rail 110 of the tape feeder 70 can be fitted into each of the plurality of slide grooves 160 of the tape feeder rack 150, and the tape feeder 70 can be slid linearly on the upper surface of the rack base 156 in a direction approaching or moving away from the rack side frame 158.

[0027] Further, the rack side frame 158 is provided with a plurality of connection terminals 166 corresponding to the plurality of slide grooves 160. Each of the plurality of connection terminals 166 has the same shape as the connection terminals 112 of the tape feeder holding table 100. Therefore, the operator fits the rails 110 of the tape feeder 70 into the slide grooves 160 of the tape feeder rack 150 and slides the tape feeder 70 in a direction approaching the rack side frame 158, so that the connector 116 is connected to the connection terminals 166. In this manner, the tape feeder 70 is positioned and stored in the tape feeder rack 150. Furthermore, the operator slides the tape feeder 70 stored in the tape feeder rack 150 in a direction away from the rack side frame 158, so that the tape feeder 70 is removed from the tape feeder rack 150. In this manner, the tape feeder 70 is positioned so as to be detachable without the operator using tools and stored in the tape feeder rack 150. Furthermore, on the rack side frame 158 , a plurality of LEDs 168 are disposed above the plurality of connection terminals 166 in correspondence with the plurality of slide grooves 160 .

[0028] 5, the tape feeder rack 150 is connected to the control device 170, and each of the multiple connection terminals 166 of the tape feeder rack 150 and the control device 170 are connected by a communication cable 172. The control device 170 has a built-in memory 176. The connection terminals 166 and the LEDs 168 arranged corresponding to each of the multiple slide grooves 160 of the tape feeder rack 150 are connected to a power source 178 by a power supply cable 177. One end of the power supply cable 177 is bifurcated, and one end of the bifurcated power supply cable 177 is connected to the connection terminals 166 and the LEDs 168 arranged corresponding to each of the multiple slide grooves 160, and the other end of the power supply cable 177 is connected to the power source 178. The power source 178 supplies power to the connection terminals 166 and the LEDs 168 or cuts off the power supply to the connection terminals 166 and the LEDs 168 in response to a control signal from the control device 170.

[0029] With this structure, a plurality of tape feeders 70 are stored in the tape feeder rack 150, and information on the types of electronic components stored in the plurality of tape feeders 70 is managed in the control device 170. In detail, when an operator desires to store a tape feeder 70 in the tape feeder rack 150, the operator first inputs identification information (hereinafter, referred to as "component ID") indicating the type of electronic component 76 of the taped component 72 set in the tape feeder 70 to the control device 170. Then, when the operator inputs the component ID to the control device 170, the control device 170 identifies a slide groove 160 in which a tape feeder 70 is not stored, and outputs a control signal to the power source 178 to supply power to the connection terminal 166 and the LED 168 corresponding to the slide groove 160. Therefore, the power source 178 supplies power to the power supply cable 177 connected to the connection terminal 166 and the LED 168 according to the control signal. As a result, the LED 168 in the tape feeder rack 150 is turned on as shown in FIG. 5. As will be described later, the control device 170 has information stored in memory 176 indicating the storage position of the tape feeder 70 stored in the tape feeder rack 150, i.e., the position of the slide groove 160 in which the tape feeder is stored or the address or number of the slide groove, so the control device 170 can identify slide grooves 160 in which a tape feeder 70 is not stored.

[0030] Then, when an LED 168 is lit in the tape feeder rack 150, the worker stores the tape feeder 70 in the slide groove 160 corresponding to the lit LED 168, as shown in Fig. 6. That is, the rail 110 of the tape feeder 70 is fitted into the slide groove 160 corresponding to the lit LED 168, and the tape feeder 70 is slid in a direction approaching the rack side frame 158, thereby connecting the connector 116 of the tape feeder 70 to the connection terminal 166. In this way, when the tape feeder 70 is stored in the slide groove 160 corresponding to the lit LED 168, power is supplied to the connection terminal 166 corresponding to the slide groove 160 together with the lit LED 168, so that power is supplied to the tape feeder 70 attached to the slide groove 160.

[0031] Next, when the connector 116 is connected to the connection terminal 166 and power is supplied to the tape feeder 70, as shown in FIG. 7, the tape feeder 70 outputs its own identification information, that is, the identification information of the tape feeder 70 (hereinafter, referred to as "feeder ID") to the control device 170 via the communication cable 172. The tape feeder 70 stores its own feeder ID. Then, when the control device 170 receives the feeder ID, it determines that a genuine tape feeder has been attached to the slide groove 160 corresponding to the connection terminal 166 and LED 168 to which power has been supplied. In other words, when the control device 170 receives the feeder ID of the attached tape feeder, the control device determines that the connector 116 of the tape feeder is connected to the connection terminal 166 of the slide groove 160 corresponding to the lit LED 168, and therefore determines that a genuine tape feeder has been attached to the slide groove 160 corresponding to the connection terminal 166 and LED 168 to which power has been supplied.

[0032] Next, when the control device 170 determines that a regular tape feeder has been attached to the slide groove 160, it outputs a control signal to the power source 178 to cut off the power supply to the connection terminal 166 and the LED 168 corresponding to that slide groove 160. Therefore, the power source 178 cuts off the power supply to the power supply cable 177 connected to the connection terminal 166 and the LED 168 corresponding to the control signal. As a result, in the tape feeder rack 150, the LED 168 corresponding to the slide groove 160 in which the tape feeder is stored is turned off. This completes the storage of the tape feeder in the slide groove 160. Note that the power supply to the tape feeder stored in the slide groove 160 together with the LED 168 is cut off, but it is not necessary to supply power to operate the tape feeder stored in the slide groove 160 of the tape feeder rack.

[0033] Furthermore, when the control device 170 receives a feeder ID via the communication cable 172, it associates in memory 176 the identification information (hereinafter referred to as the "storage position ID") of the slide groove 160 corresponding to the connection terminal 166 to which the communication cable 172 is connected, the previously input part ID, and the feeder ID received via the communication cable 172. In other words, the storage position ID of the slide groove 160 in which the tape feeder is stored, the feeder ID of the tape feeder 70 stored in the slide groove 160, and the part ID of the electronic part set in the tape feeder 70 are stored in memory 176 in association with each other. In this way, simply by storing tape feeder 70 in slide groove 160 corresponding to the lit LED 168 of tape feeder rack 150, the control device 170 manages in association with the tape feeder (feeder ID) stored in tape feeder rack 150, the storage position of that tape feeder (storage position ID), and the type of electronic component (component ID) set in that tape feeder.

[0034] In addition, when a new type of electronic component becomes necessary in the mounting work of the electronic components in the mounting machine 16, the tape feeder in which the tape-formed component 72 of the newly required type of electronic component is set can be easily taken out from the tape feeder rack 150. In detail, the part ID of the type of electronic component newly required in the mounting work of the electronic components in the mounting machine 16 is input to the control device 170 by the worker. When the part ID is input to the control device 170, the control device 170 identifies the input part ID from the part IDs stored in the memory 176. Then, the control device 170 extracts the storage position ID stored in the memory 176 in association with the identified part ID. Next, the control device 170 outputs a control signal to the power source 178 to supply power to the connection terminal 166 and the LED 168 corresponding to the slide groove 160 identified by the extracted storage position ID. Therefore, the power source 178 supplies power to the power supply cable 177 connected to the connection terminal 166 and the LED 168 in response to the control signal. As a result, in the tape feeder rack 150, the LED 168 is lit as shown in FIG. 8. Then, the worker removes the tape feeder from the tape feeder rack 150 by sliding the tape feeder stored in the slide groove 160 corresponding to the lit LED 168 in a direction away from the rack side frame 158. This allows the worker to easily select and remove from the tape feeder rack 150 the tape feeder in which the taped components 72 of the newly required type of electronic component are set. Then, the worker mounts the tape feeder removed from the tape feeder rack 150 on the tape feeder holding table 100 of the mounting machine 16, thereby performing the mounting work of the new electronic component in the mounting machine 16.

[0035] In this way, by using the information managed in the control device 170, it is possible to easily select and take out from the tape feeder rack 150 a tape feeder in which the tape-formed components 72 of the required type of electronic components are set, simply by inputting the component ID of the required type of electronic component to the control device 170. In addition, in the tape feeder rack 150, one power supply cable 177 branched into two is connected to the connection terminals 166 and LEDs 168 corresponding to each of the multiple slide grooves 160, and power is supplied from the power source 178 through the single power supply cable 177, thereby reducing costs and simplifying the structure. In detail, in the conventional tape feeder rack, it was necessary to prepare a terminal cable for constantly supplying power to the connection terminals 166 corresponding to each of the multiple slide grooves 160, and a remote IO module (control board) for turning on and off the LEDs 168 corresponding to each of the multiple slide grooves 160. In other words, it was necessary to prepare multiple terminal cables corresponding to the multiple connection terminals 166 and multiple remote IO modules corresponding to the multiple LEDs 168. In this way, when a plurality of terminal cables and a plurality of remote IO modules are arranged in the tape feeder rack, the cost increases and the structure of the tape feeder rack becomes complicated. On the other hand, since it is not necessary to supply power to the tape feeders stored in the tape feeder rack, in the tape feeder rack 150, one power supply cable 177 branched into two is connected to the connection terminals 166 and the LEDs 168 corresponding to each of the plurality of slide grooves 160, and power is supplied from the power source 178 through the one power supply cable 177. In other words, the one power supply cable 177 functions as a cable for supplying power to the tape feeders mounted in the tape feeder rack 150 and as an output IO to the LEDs 168. This reduces the cost and simplifies the structure of the tape feeder rack 150.

[0036] The tape feeder 70 is an example of a feeder. The slide groove 160 is an example of a slot. The LED 168 is an example of an indicator light. The control device 170 is an example of a control device.

[0037] The present invention is not limited to the above embodiment, and can be embodied in various forms with various modifications and improvements based on the knowledge of a person skilled in the art. Specifically, for example, in the above embodiment, power is supplied to the LEDs 168 corresponding to each of the plurality of slide grooves 160 by the power supply cable 177 that supplies power to the connection terminals 166 corresponding to each of the plurality of slide grooves 160, and the LEDs 168 are turned on. On the other hand, power may be supplied to the LEDs 168 corresponding to each of the plurality of slide grooves 160 by a cable different from the power supply cable 177 that supplies power to the connection terminals 166 corresponding to each of the plurality of slide grooves 160, and the LEDs 168 may be turned on. In other words, power may be supplied to the connection terminals 166 by a power supply cable for the connection terminals, and power may be supplied to the LEDs 168 by a power supply cable for the LEDs. In this way, when power is supplied to the connection terminal 166 through a power supply cable for the connection terminal, and power is supplied to the LED 168 through a power supply cable for the LED, for example, even if the power supply to the connection terminal 166 is cut off, the power supply to the LED 168 may not be cut off and the power supply to the LED 168 may be maintained. In other words, when the power supply to the connection terminal 166 is cut off, the power supply to the LED 168 may be maintained and the lighting of the LED 168 may be maintained. Also, when power is supplied to the connection terminal 166 through a power supply cable for the connection terminal, and power is supplied to the LED 168 through a power supply cable for the LED, for example, even if the power supply to the LED 168 is cut off and the LED 168 is turned off, the power supply to the connection terminal 166 may not be cut off and the power supply to the connection terminal 166 may be maintained.

[0038] Furthermore, in the above embodiment, when the control device 170 receives a feeder ID, the control device 170 determines that a genuine tape feeder is stored in the slide groove 160, but when the feeder ID received by the control device 170 matches a preset ID, the control device 170 may determine that a genuine tape feeder is stored in the slide groove 160. Furthermore, the control device 170 may determine that a genuine tape feeder is stored in the slide groove 160 when it receives other information, not limited to the feeder ID, for example, information indicating that the connector 116 of the tape feeder is connected to the connection terminal 166.

[0039] Furthermore, in the above embodiment, power is supplied to the tape feeder housed in the slide groove 160 via the connector 116, but power may be supplied to the tape feeder via the tape feeder rail 110. Furthermore, power may be supplied from the tape feeder rack to the tape feeder housed in the slide groove 160 in a non-contact manner, without coming into contact with the tape feeder.

[0040] Furthermore, in the above embodiment, the part ID of the electronic part is input by the worker to the control device 170, but the part ID of the electronic part may be input to the tape feeder. In this manner, when the part ID is input to the tape feeder, when the tape feeder is stored in the tape feeder rack 150, the part ID and feeder ID are output from the tape feeder stored in the tape feeder rack 150 to the control device 170 via the communication cable 172.

[0041] Also, in the above embodiment, the storage position ID, the feeder ID, and the part ID are stored in association with each other in the memory 176 of the control device 170, but the storage position ID, the feeder ID, and the part ID may be stored in association with each other in a device different from the control device 170, for example, a server, a PC other than the control device, etc. In other words, when the control device 170 receives a feeder ID from a tape feeder stored in the tape feeder rack 150, the control device 170 may output the feeder ID, the storage position ID, and the part ID to a server or the like, and the server or the like may store the feeder ID, the storage position ID, and the part ID in association with each other.

[0042] In the above embodiment, the tape feeder is stored in the tape feeder rack by fitting the rail 110 of the tape feeder into the slide groove 160, but the tape feeder can be stored in the tape feeder rack in various ways as long as the tape feeder can be stored in the tape feeder rack. For example, the tape feeder can be stored in the tape feeder rack by forming a rail, a recess, a holder, etc. in the feeder rack and holding the tape feeder by the rail, the recess, the holder, etc. In the above embodiment, the tape feeder is stored in the tape feeder rack in a positioned state, but the tape feeder may be stored in the tape feeder rack without being positioned. In the above embodiment, the tape feeder is positioned and stored in the tape feeder rack with one touch by the worker without using tools, but the worker may use tools to store the tape feeder in the tape feeder rack. The tape feeder may be automatically stored in the tape feeder rack using an articulated robot, a multi-axis robot, etc.
