BEST MODE FOR CARRYING OUT THE INVENTION

[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] 1 shows an electronic component mounting apparatus 10. The electronic component mounting apparatus 10 comprises a mounting machine main body 20, a transport device 22, a mounting head moving device (hereinafter abbreviated as "moving device") 24, a mounting head 26, a supply device 28, and a control device (see FIG. 3) 30. The mounting machine main body 20 is composed of a frame 32 and a beam 34 suspended from the frame 32.

[0011] 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 a predetermined direction. The direction in which the conveyor devices 40, 42 extend is referred to as the X-axis direction, and the horizontal direction perpendicular to that direction is referred to as the Y-axis direction. Each of the two conveyor devices 40, 42 transports a circuit board supported by each conveyor device 40, 42 in the X-axis direction by an electromagnetic motor (see FIG. 3) 46. The circuit board is held at a predetermined position by a board holding device (see FIG. 3) 48.

[0012] The moving device 24 is an XY robot type moving device. The moving device 24 is equipped with an electromagnetic motor (see FIG. 3) 52 that slides the slider 50 in the X-axis direction, and an electromagnetic motor (see FIG. 3) 54 that slides it 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 52, 54.

[0013] The placing head 26 places electronic components on the circuit board. The placing 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 (see FIG. 3) 62 via negative pressure air and positive pressure air passages. The suction nozzle 60 sucks and holds electronic components by negative pressure, and releases the held electronic components by positive pressure. The placing head 26 also has a nozzle lifting device (see FIG. 3) 64 that raises and lowers the suction nozzle 60. The nozzle lifting device 64 allows the placing head 26 to change the vertical position of the electronic component it is holding.

[0014] The supply device 28 is disposed at the front end of the frame 32 and includes multiple tape feeders 70. As shown in FIG. 2, each tape feeder 70 includes a reel 72, a delivery device 74, and a peeling device 76, and supplies electronic components at the end of the top surface. Specifically, a tape component 78 is wound around the reel 72, and the reel 72 around which the tape component 78 is wound is stored in a reel storage section 79. The tape component 78 is pulled out from the reel 72 stored in the reel storage section 79 onto a tape guide 80. The tape component 78 is formed by taping electronic components and has feed holes (not shown) formed at a predetermined pitch. A sprocket 82 of the delivery device 74 engages with the feed holes. The sprocket 82 is rotated by an electromagnetic motor 84. With this structure, the tape component 78 is delivered toward the supply position. An encoder 85 (see FIG. 3) is provided on the electromagnetic motor 84. The encoder 85 detects the drive position, i.e., the rotation angle, of the electromagnetic motor 84, which is the drive source of the delivery device 74, and the operation of the electromagnetic motor 84 is controlled based on the value detected by the encoder 85. The encoder 85 is an absolute encoder, and detects the absolute rotation angle of the electromagnetic motor. In other words, an origin is set in the encoder 85, and the rotation angle from the origin is detected. Therefore, as long as the electromagnetic motor 84 does not rotate, the rotation angle detected by the encoder 85 does not change even after the power supply to the electromagnetic motor is cut off.

[0015] The peeling device 76 also includes a film peeling mechanism 86 and a gear mechanism 88. The film peeling mechanism 86 is a mechanism for peeling the top film 90 from the tape-formed component 78 and is disposed in front of an opening 92 formed at the top end of the tape feeder 70. The gear mechanism 88 is a mechanism for pulling the top film 90 peeled from the tape-formed component 78 into a film recovery section 94. With this structure, when the top film 90 is peeled from the tape-formed component 78, the electronic components housed in the tape-formed component 78 are exposed at the opening 92, and the exposed electronic components are sucked and held by the suction nozzles 60 of the mounting head 26. In other words, the opening 92 serves as the electronic component supply position of the tape feeder 70. A tape guide passage 96 is formed on the side of the opening 92 facing the feeding direction of the tape-formed component 78, extending downward. Through this tape guide passage 96, waste tape 98 from which electronic components have been removed from the tape-formed component 78 is discharged.

[0016] A connector 100 is disposed on a side surface of the tape feeder 70 in the feeding direction of the tape component 78. Meanwhile, as shown in FIG. 1 , a tape feeder mounting base 110 is disposed at the front end of the frame 32. The tape feeder mounting base 110 is composed of an erected surface 112 that stands perpendicular to the frame 32 and a protruding surface 114 that protrudes from the lower end of the erected surface 112. A plurality of slide grooves 116 are formed in the protruding surface 114 so as to extend in the Y direction, and the erected surface 112 is provided with connector connection portions 118 corresponding to each of the plurality of slide grooves 116. The lower end of the tape feeder 70 is fitted into the slide grooves 116, and the connector 100 of the tape feeder 70 is connected to the connector connection portion 118. Thus, the tape feeder 70 is positioned and mounted on the tape feeder mounting base 110, and is electrically connected.

[0017] As shown in FIG. 3 , the control device 30 includes a controller 130, multiple drive circuits 132, a control circuit 133, and a memory 134. The multiple drive circuits 132 are connected to the electromagnetic motors 46, 52, 54, and 84, the substrate holding device 48, and the positive / negative pressure supply device 62. The controller 130 is a computer-based device including a CPU, ROM, RAM, and the like, and is connected to the multiple drive circuits 132. This allows the controller 130 to control the operation of the conveying device 22, the moving device 24, and the like. The controller 130 is also connected to the encoder 85 of the tape feeder 70, and controls the operation of the electromagnetic motor 84 of the tape feeder 70, i.e., the feeding device 74, based on the detection value of the encoder 85. The controller 130 is also connected to a display device 136 via the control circuit 133. This allows the controller 130 to display any image on the display device 136. The controller 130 is also connected to the memory 134. This allows the controller 130 to store various types of information in the memory 134 and acquire various types of information from the memory 134 .

[0018] In electronic component mounting apparatus 10, with the above-described configuration, mounting head 26 performs a mounting operation on a circuit board held by conveyance device 22. Specifically, in response to a command from controller 130, the circuit board is conveyed to the operation position, where it is fixedly held by board holding device 48. In response to a command from controller 130, tape feeder 70 feeds tape-formed components and supplies electronic components at the supply position. Then, in response to a command from controller 130, mounting head 26 moves to a position above the electronic component supply position and sucks and holds the electronic components with suction nozzle 60. Then, mounting head 26 moves to a position above the circuit board and mounts the electronic components on the circuit board.

[0019] In this way, electronic component mounting apparatus 10 mounts electronic components supplied by tape feeder 70 onto a circuit board. For this reason, it is necessary to properly manage the types of electronic components supplied by tape feeder 70 and the identification information for identifying that tape feeder 70. In other words, it is necessary to properly manage the types of electronic components wound on reels 72 housed in tape feeder 70 and the identification information of the tape feeder. For this reason, when reels 72 are housed in tape feeder 70, the registration information of the electronic components is registered.

[0020] Specifically, when tape-packaged components are attached to tape feeder 70 using loading device 150 shown in FIG. 4, the registration information of the electronic components is registered. Loading device 150 is composed of kitting stand 152 and control device 154. Kitting stand 152 has a mounting base 160, stand 162, and upper rail 164. Mounting base 160 supports the bottom surface of the tape feeder, and the bottom surface of the tape feeder is placed on the upper surface of mounting base 160. Stand 162 is erected on the upper surface of mounting base 160 and supports the side surface of the tape feeder placed on mounting base 160. Upper rail 164 is disposed at the upper end of stand 162, and the upper end surface of the tape feeder placed on mounting base 160 fits into upper rail 164. The tape feeder is set in kitting stand 152 in this position. Additionally, a bracket 166 is fixed to the front side edge of stand 162 so as to cover the front side wall of the tape feeder set in kitting stand 152, and a connector connection part 168 is disposed on bracket 166. Therefore, when the tape feeder is set in kitting stand 152, connector 100 of the tape feeder is connected to connector connection part 168. As a result, tape feeder 70 is set in a positioned state on kitting stand 152 and is electrically connected.

[0021] The control device 154 is connected to the connector 168 of the kitting stand 152 and controls the operation of the tape feeder set on the kitting stand 152. The control device 154 includes a controller 170 and a drive circuit 172. The controller 170 is mainly a computer including a CPU, ROM, RAM, etc., and is connected to the drive circuit 172. When a tape feeder is set on the kitting stand 152, the drive circuit 172 is connected to the electromagnetic motor 84 of the tape feeder. When a tape feeder is set on the kitting stand 152, the controller 170 is connected to the encoder 85 of the tape feeder. This allows the controller 170 to control the operation of the electromagnetic motor 84 of the tape feeder 70, i.e., the feeding device 74, based on the detection value of the encoder 85. A code reader 176 is also connected to the controller 170. The control device 154 is connected to the control device 30 of the electronic component mounting apparatus 10, and various information is transmitted and received between the control device 154 and the control device 30.

[0022] In the loading device 150 having such a structure, when a tape-formed component is attached to the tape feeder 70, registration information for the electronic component is registered. More specifically, a barcode is affixed to the reel 72 around which the tape-formed component is wound. The barcode encodes component information indicating the type of electronic component stored in the tape-formed component wound on the reel 72. An operator then reads the barcode of the reel 72 to be stored in the tape feeder using the code reader 176. As a result, the controller 170 obtains the component information for the tape-formed component wound on the reel 72.

[0023] Furthermore, the worker reads the barcode on reel 72 with code reader 176, stores reel 72 in reel storage section 79 of the tape feeder, and sets the tape feeder on kitting stand 152. This electrically connects the tape feeder to control device 154. At this time, controller 170 acquires tape feeder identification information from the tape feeder. Then, controller 170 transmits the component information read by code reader 176 and the tape feeder identification information acquired from the tape feeder to control device 30 of electronic component mounting apparatus 10. As a result, when control device 30 receives the component information and tape feeder identification information, it associates the received component information with the tape feeder identification information and stores them in memory 134 as registration information for the electronic components.

[0024] After setting the tape feeder in the kitting stand 152, the worker pulls out the leading end of the tape component from the reel 72 stored in the tape feeder and feeds it along the upper surface of the tape guide 80. At this time, the worker feeds the tape component until the feed hole in the leading end of the tape component engages with the sprocket 82 of the feeding device 74. Then, after the worker feeds the tape component until the feed hole in the tape component engages with the sprocket 82 of the feeding device 74, the worker operates an operation button (not shown) disposed on the stand 162. The operation button operates the electromagnetic motor 84 of the tape feeder while being operated. When the electromagnetic motor 84 is operated by operating the operation button, the tape component engaged with the sprocket 82 is fed toward the feed position. Therefore, the worker operates the operation button while checking the tape component engaged with the sprocket 82. Then, when the leading end of the tape component is fed to a predetermined position, for example, the feed position, the worker stops operating the operation button. As a result, the taped components are attached to the tape feeder 70 by the loading device 150. When the taped components are attached to the tape feeder 70 using the loading device 150, the component information and the identification information of the tape feeder are associated with each other and stored in the memory 134 in the control device 30 of the electronic component mounting apparatus 10, thereby registering the registration information of the electronic components. When the taped components are attached to the tape feeder, not only is the taped components fed out by the electromagnetic motor 84, but also the top film peeled from the taped components is set in the film peeling mechanism 86, and so on; however, a description of the top film setting operation will be omitted.

[0025] In this way, when the tape-formed components are attached to the tape feeder, the tape feeder is attached to the tape feeder attachment stand 110 of the electronic component mounting apparatus 10, and electronic components are supplied from the tape-formed components attached to the tape feeder, thereby performing the component mounting operation. Therefore, when the tape feeder is attached to the tape feeder attachment stand 110 of the electronic component mounting apparatus 10, a verification operation for the electronic components is performed. Specifically, when the tape feeder is attached to the tape feeder attachment stand 110, the tape feeder is electrically connected to the control device 30 of the electronic component mounting apparatus 10. At this time, the controller 130 of the control device 30 acquires tape feeder identification information from the tape feeder. Then, the controller 130 extracts the identification information of the tape feeder attached to the tape feeder attachment stand 110 from the tape feeder identification information stored in the memory 134. The controller 130 then identifies the component information stored in the memory 134 in association with the extracted tape feeder identification information. The controller 130 then checks whether the type of electronic component indicated by the identified component information matches the type of electronic component to be mounted in the mounting operation by the electronic component mounting apparatus 10, i.e., performs an electronic component verification operation. If the type of electronic component indicated by the component information matches the type of electronic component to be mounted in the mounting operation by the electronic component mounting apparatus 10, the mounting operation by the electronic component mounting apparatus 10 is performed. This ensures that the components are mounted appropriately. In this way, the electronic component mounting apparatus 10 performs a verification operation of the electronic components on the tape feeders mounted on the tape feeder mounting table 110.

[0026] However, if a tape feeder is mounted on the tape feeder mounting stand 110 immediately after a tape component is attached to the tape feeder by the kitting stand 152, it is unlikely that the reel has been replaced. On the other hand, if a tape feeder is mounted on the tape feeder mounting stand 110 after a certain amount of time has passed since a tape component was attached to the tape feeder by the kitting stand 152, it is highly likely that the reel has been replaced. In other words, it is highly likely that the reel has been replaced after the registration information of the electronic component was registered. In this way, if a reel is replaced after the registration information of the electronic component is registered and the tape feeder with the replaced reel is mounted on the tape feeder mounting stand 110, the verification operation cannot be performed properly.

[0027] For this reason, in conventional methods, if a predetermined time has elapsed since the registration information of an electronic component was registered, the registration information is erased. Therefore, if a predetermined time has elapsed since the registration information of an electronic component was registered, the registration information of the electronic component is re-registered, and then a verification operation for the electronic component is performed. By performing the verification operation for the electronic component after the registration information of the electronic component is re-registered in this manner, an appropriate verification operation is ensured. However, re-registering the registration information of the electronic component places a burden on the worker. In particular, in a case where the tape feeders are stored after the tape-packaged components are attached to the tape feeders in the kitting stand 152, it is necessary to re-register the registration information of the electronic components for many tape feeders, which places a significant burden on the worker. Furthermore, there is a risk that some workers will avoid re-registering the registration information of the electronic components and will not perform the verification operation at all.

[0028] In view of this, in the electronic component mounting apparatus 10, even if a predetermined time has passed since the registration information of the electronic components was registered, the registration information is not erased and a verification operation is performed. However, to ensure an appropriate verification operation, whether or not the reel has been replaced is determined based on the value detected by the encoder of the tape feeder.

[0029] More specifically, as described above, when a tape component is attached to a tape feeder in the kitting stand 152, the control device 154 transmits the component information and the tape feeder identification information to the control device 30, and the control device 30 stores the component information and the tape feeder identification information in the memory 134 as registration information. At this time, the control device 154 transmits not only the component information and the tape feeder identification information to the control device 30, but also the detection value of the encoder 85 when the tape component is attached to the tape feeder. Specifically, the control device 154 acquires the detection value of the encoder 85 when attachment of the tape component to the tape feeder is complete (hereinafter referred to as the "detection value at component attachment"). In other words, once attachment of the tape component to the tape feeder is complete, the electromagnetic motor 84 does not operate, and therefore the control device 154 acquires the detection value of the encoder 85 after attachment of the tape component to the tape feeder is complete. Then, the control device 154 transmits the acquired detection value of the encoder 85, that is, the component installation detection value, the component information, and the tape feeder identification information, to the control device 30. Then, the control device 30 associates the component installation detection value, the component information, and the tape feeder identification information and stores them in the memory 134. As a result, the component installation detection value, the component information, and the tape feeder identification information are registered as registration information. This registration information is not erased even after a predetermined time has passed.

[0030] Furthermore, when a tape feeder is mounted on the tape feeder mounting stand 110 of the electronic component mounting apparatus 10 and electrically connected to the control device 30 of the electronic component mounting apparatus 10, the controller 130 of the control device 30 acquires the identification information of the tape feeder from the tape feeder. Furthermore, the controller 130 acquires the detection value of the encoder 85 from the tape feeder (hereinafter referred to as the "mounting detection value"). The controller 130 then extracts the identification information of the tape feeder mounted on the tape feeder mounting stand 110 from the tape feeder identification information stored in the memory 134. Next, the controller 130 identifies the component mounting detection value stored in the memory 134 in association with the extracted tape feeder identification information. The controller 130 then compares the component mounting detection value stored in the memory 134 with the mounting detection value acquired from the tape feeder mounted on the tape feeder mounting stand 110. As described above, the encoder 85 is an absolute encoder, and therefore, unless the electromagnetic motor 84 rotates, the rotation angle detected by the encoder 85 does not change, even after the power supply to the electromagnetic motor is cut off. Therefore, if the component installation detection value and the installation detection value are the same, it is presumed that the electromagnetic motor 84 is not operating. Furthermore, if the reel 72 in the tape feeder is replaced, the tape-formed components on the replaced reel 72 must be attached to the tape feeder, and the electromagnetic motor 84 operates when the tape-formed components are fed out. In other words, if the component installation detection value and the installation detection value are the same, it is presumed that the reel 72 in the tape feeder has not been replaced. On the other hand, if the component installation detection value and the installation detection value are different, it is presumed that the reel 72 in the tape feeder has been replaced.

[0031] Therefore, if the component installation detection value and the mounting detection value are the same, the controller 130 executes a verify operation. That is, the controller 130 identifies component information stored in the memory 134 in association with the tape feeder identification information extracted from the tape feeder identification information stored in the memory 134. The controller 130 then confirms whether the type of electronic component indicated by the identified component information matches the type of electronic component to be mounted in the mounting operation by the electronic component mounting apparatus 10, that is, performs an electronic component verification operation. In this way, by performing the verify operation when the component installation detection value and the mounting detection value are the same, that is, when it is estimated that the reel 72 has not been replaced in the tape feeder, it is possible to ensure that the verification operation is performed appropriately.

[0032] On the other hand, if the detected value at component attachment and the detected value at mounting are different, it is estimated that the reel 72 has been replaced in the tape feeder, and the controller 130 displays a warning screen on the display device 136. This warning screen displays a comment urging the user to re-register component information because the reel has been replaced in the tape feeder mounted on the tape feeder mounting stand 110. This makes it possible to prevent electronic components from being supplied from the reel 72 that was replaced after the component information was registered, and ensures proper component mounting work.

[0033] 3, the controller 130 of the control device 30 has a first acquisition unit 180, a second acquisition unit 182, and a determination unit 184. The first acquisition unit 180 is a functional unit for acquiring, via the kitting stand 152, the detection value of the encoder 85 when a tape-formed component is attached to the tape feeder. The second acquisition unit 182 is a functional unit for acquiring, via the electronic component mounting device 10, the detection value of the encoder 85 when the tape feeder with the tape-formed component attached is attached to the tape feeder mounting table 110. The determination unit 184 is a functional unit for determining whether or not the reel 72 in the tape feeder has been replaced based on the detection value at component attachment and the detection value at mounting.

[0034] Furthermore, in the first embodiment described above, whether or not the reel needs to be replaced is determined based on the detection value of encoder 85 of delivery device 74 in the tape feeder, but in the second embodiment, whether or not the reel needs to be replaced is determined based on the opening and closing of the reel cover in the tape feeder. Specifically, in the second embodiment, a tape feeder 200 shown in Fig. 5 is used. Tape feeder 200 has almost the same structure as tape feeder 70 of the first embodiment, except for reel cover 202, and therefore, a description of the configuration other than reel cover 202 will be omitted, and the same reference numerals as those in the configuration of tape feeder 70 will be used.

[0035] A reel storage section 79 that opens to the side is formed in a housing 206 of the tape feeder 200. The reel cover 202 has a generally flat plate shape and is disposed so as to close the opening of the reel storage section 79 in the side of the housing 206. The reel cover 202 is supported at its upper end by a pair of hinges 208 so as to be able to swing. As a result, by swinging the reel cover 202 downward, the reel cover 202 closes and closes the reel storage section 79. On the other hand, as shown in FIG. 6 , by swinging the reel cover 202 upward, the reel cover 202 opens and exposes the reel storage section 79. Therefore, when a reel 72 is stored in the reel storage section 79, the reel 72 can be removed from the reel storage section 79 by opening the reel cover 202. Furthermore, when the reel 72 is not stored in the reel storage section 79, the reel cover 202 can be opened to store the reel 72 in the reel storage section 79. When the tape feeder 200 storing the reel 72 is used, the reel cover 202 is closed. Therefore, when replacing the reel 72, the reel cover 202 is always opened and closed.

[0036] The tape feeder 200 also has built-in detection sensor 210 that detects whether the reel cover 202 is open or closed, and memory 212 that stores the detection results of the detection sensor 210. The tape feeder 200 also has built-in battery 214 that supplies power to the detection sensor 210 and memory 212. As a result, even if the reel cover 202 is opened or closed in the tape feeder 200 that is not powered, the opening or closing of the reel cover 202 is detected by the detection sensor 210, and the detection results of the detection sensor 210 are stored in the memory 212. In the memory 212, when the opening or closing of the reel cover 202 is detected by the detection sensor 210 and the detection results of the detection sensor 210 are stored in the memory 212, an opening or closing flag is set to ON, and when the opening or closing of the reel cover 202 is not detected by the detection sensor 210, the opening or closing flag is set to OFF.

[0037] When tape components are attached to tape feeder 200 having such a structure using kitting stand 152, reel cover 202 may be opened or closed. In such a case, detection sensor 210 detects whether reel cover 202 is open or closed, and the detection result is stored in memory 212. That is, an open / close flag is turned ON in memory 212. Furthermore, when tape feeder 200 is set in kitting stand 152 and code reader 176 reads the barcode affixed to the reel, control device 154 transmits component information and identification information of tape feeder 200 to control device 30. As a result, registration information of the electronic component is registered in control device 30. Then, after transmitting the component information and identification information of tape feeder 200 to control device 30, control device 154 outputs a command to erase memory 212 to tape feeder 200. As a result, the detection result by detection sensor 210 stored in memory 212 is erased. That is, after the registration information of the electronic component is registered, the open / close flag in memory 212 is turned OFF. Therefore, the open / close flag in memory 212 is maintained OFF unless reel cover 202 of tape feeder 200 is opened or closed after the registration information of the electronic component is registered. On the other hand, if reel cover 202 of tape feeder 200 is opened or closed even once after the registration information of the electronic component is registered, the open / close flag in memory 212 is turned ON.

[0038] When the tape feeder 200 is mounted on the tape feeder mounting table 110 to be used in a mounting operation by the electronic component mounting apparatus 10, the controller 130 of the control device 30 acquires identification information from the tape feeder 200. At this time, the controller 130 acquires not only the identification information from the tape feeder 200 but also information stored in the memory 212, i.e., information indicating whether the open / close flag is ON or OFF. At this time, if the open / close flag is OFF, it is assumed that the reel cover 202 of the tape feeder 200 has never been opened or closed after the registration information of the electronic component was registered, and therefore the reel 72 has not been replaced in the tape feeder. Therefore, if the open / close flag is OFF, the verify operation is performed according to the procedure described above. On the other hand, if the open / close flag is ON, it is assumed that the reel cover 202 of the tape feeder 200 has been opened and closed after the registration information of the electronic component was registered, and therefore the reel 72 has been replaced in the tape feeder. Therefore, when the open / close flag is ON, the warning screen described above is displayed on the display device 136. As a result, the second embodiment can also achieve the same effects as the first embodiment.

[0039] In the above embodiment, the electronic component mounting apparatus 10 is an example of a substrate-related operation machine. The control device 30 is an example of a control device. The tape feeder 70 is an example of a feeder. The feeding device 74 is an example of a feeding device. The taped component 78 is an example of a taped component. The electromagnetic motor 84 is an example of a drive source. The encoder 85 is an example of an encoder. The kitting stand 152 is an example of a mounting device. The electronic component mounting apparatus 10 and the kitting stand 152 constitute an example of a work system. The tape feeder 200 is an example of a feeder. The process executed by the first acquisition unit 180 is an example of a first acquisition process. The process executed by the second acquisition unit 182 is an example of a second acquisition process. The process executed by the determination unit 184 is an example of a determination process.

[0040] Furthermore, the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made based on the knowledge of those skilled in the art. Specifically, for example, in the above-described embodiment, tape feeders 70 and 200 are used as feeders for supplying components from tape-packaged components, but various feeders can be used. Specifically, for example, various feeders can be used, such as tape feeders that supply lead components from tape-packaged components in which lead components such as axial lead components and radial lead components are taped.

[0041] Furthermore, although the above embodiment employs an absolute encoder 85 that detects the rotation angle of the electromagnetic motor 84, an incremental encoder may also be employed. However, because an incremental encoder detects the relative rotation angle of the electromagnetic motor, it is necessary to provide the tape feeder with a memory that stores the rotation angle and a battery that supplies power to the memory.

[0042] In the above embodiment, a kitting stand 152 is used as a device for attaching tape components to the tape feeder. That is, a device is used in which an operator feeds the leading end of a tape component to a predetermined position in the tape feeder and then operates an operation button to attach the tape component to the tape feeder. Alternatively, a so-called autoloading device may be used that automatically performs the operations of feeding the leading end of a tape component to a predetermined position in the tape feeder and feeding out the tape component.

[0043] In the above embodiment, the memory 134 for storing registration information and the like is provided in the control device 30, but it may be provided in a host management device that manages the cloud or the electronic component mounting device 10, or the like. [Explanation of symbols]
