Based on the feeder information obtained by receiving the information recorded in the tag chip 98, the component information and the feeder information are read from the host computer 240. Only part information may be read. The component identification code (type) of the component 54 supplied at the mounting position where the feeder 50 is mounted is obtained from the mounting position data and the feeder information obtained by reading and the previously obtained component information and feeder information. Then, it is determined whether or not the combination of the mounting position and the component identification code of the component 54 matches the combination set in the component mounting data.

  If the above combinations match, the determination result in S3 is YES and execution of the routine ends. If the combination does not match, the determination result of S3 is NO and S4 is executed, and the mismatch of the combination is displayed on the display screen 254 to notify the operator. The display screen 254 also displays, for example, the mounting position where the mismatch occurred, the information of the mounted feeder 50, the information of the component 54, and the like, and the operator can redo the mounting of the feeder 50 according to the display. Confirmation of the type of the component 54 held by the feeder 50 mounted on the feeder support base 48 is performed when all the feeders 50 that supply the component 54 to one type of printed wiring board 30 are mounted on the feeder support base 48. The mounting position and the component information are stored in the RAM 224 of the mounting control computer 230 in association with each other.

However, the setup change was similarly performed for the tray-type component supply device 20, and the component tray 110 that supplies the component 54 to the printed wiring board 30 was accommodated. The component tray storage box 114 is supported by the support member, and the type of the component 54 is confirmed. In the tray-type component supply device 20, the support member that supports the component tray storage box 114 is moved up and down by the lifting device, and a number is assigned to each of the plurality of support members. A mounting position or stack position that is the vertical position of the component 54 accommodated in the tray 110 is designated. This number plays the same role as the number assigned to the slot of the feeder support base 48 in the feeder-type component supply device 18 and will not be described. However, as with the feeder-type component supply device 18, the type of the component 54 is confirmed. Is done.

  If the type of the printed wiring board 30 on which the component 54 is mounted changes and the type of the suction nozzle 170 used for mounting changes, the suction nozzle 170 is replaced. At least one suction nozzle 170 is used for mounting the component 54 on one type of printed wiring board 30. As will be described in detail later, the suction nozzle 170 changes the type of the printed wiring board 30, and if necessary. The nozzle stocker 186 is replaced. The mounting head 130 is moved to the nozzle stocker 186 by the XY robot 132 and holds the suction nozzle 170 accommodated in the nozzle stocker 186. At this time, the suction nozzle recorded on the tag chip 180 of the suction nozzle 170 is retained. Based on the information, 170 types of adsorption are identified.

  As will be described later, in a state where the nozzle stocker 186 is set on the bed 10, nozzle accommodation information that associates the nozzle accommodation position with the suction nozzle information in the nozzle stocker 186 is acquired and stored in the mounting control computer 230, and the mounting head 130 is moved to the nozzle holding hole 284 in which the suction nozzle 170 to be held is accommodated. Then, prior to holding the suction nozzle 170, it is confirmed whether or not the type of the suction nozzle 170 accommodated matches the type of the suction nozzle 170 to be held.

  The type of the suction nozzle 170 is confirmed according to the nozzle type confirmation routine shown in FIG. 12, and information recorded on the tag chip 180 provided on the background forming plate 176 of the suction nozzle 170 is read by the reader / writer 200, thereby The type of the suction nozzle 170 is confirmed based on whether or not the type of the obtained suction nozzle 170 matches the preset type. At the time of reading, the reader / writer 200 is positioned at the lower end position.

  The reader / writer 200 is moved by the XY robot 132 onto the suction nozzle 170 that is scheduled to be used, and information recorded on the tag chip 180 is received. This reception is performed with the reader / writer 200 being moved. Thereby, the determination result of S11 is YES, S12 is executed, and it is determined whether or not the type of the suction nozzle 170 is a type to be held. By reading the information recorded on the tag chip 180, the type of the suction nozzle 170 accommodated is known, and it is determined whether or not it matches the type of the suction nozzle 170 to be held. The determination result of S12 is YES, the execution of the routine ends, and the suction nozzle 170 is held by the mounting head 130. If the type of the suction nozzle 170 stored is not the set type, that is, if it is not the suction nozzle 170 of the type associated with the nozzle storage position in the nozzle storage information, the determination result in S12 is NO and S13 Is executed, and the type of the suction nozzle 170 accommodated in the nozzle holding hole 824 is not the set type, the nozzle accommodation position, the type of the suction nozzle 170 to be held, and the like are displayed on the display screen 254 and notified. . Accordingly, for example, an operator can take appropriate measures such as checking and replacing the suction nozzle 170 accommodated in the nozzle stocker 186.

  Checking the type of the mounting head 130 when the mounting head 130 holds the suction nozzle 170 in this way is one mode of use of the suction nozzle information, but the suction nozzle information is also used in other modes. This will be described in detail later.

  When the setup change is completed, the operation of mounting the component 54 on the printed wiring board 30 is started. The printed wiring board 30 is carried in by the wiring board conveying device 12, stopped at the mounting work position by the stop device, and held by the printed wiring board holding device 14. The information recorded in the memory 40 of the tag chip 36 provided on the printed wiring board 30 is received by the reader / writer 200, and the wiring board ID and the like are acquired. The position where the tag chip 36 is provided on the printed wiring board 30 is known by design, and the reader / writer 200 is moved onto the tag chip 36 by the XY robot 132 based on the position of the tag chip 36 and the stop position of the printed wiring board 30. The information recorded in the tag chip 36 is received and read. At this time, the reader / writer 200 performs reception at the lower end position.

  Further, the reference mark 34 provided on the printed wiring board 30 is imaged by the wiring board imaging system 22, and the obtained image data is processed by the image processing computer 238, whereby a horizontal position is obtained for each of the plurality of component mounting positions. An error (position errors in the X-axis and Y-axis directions) is obtained.

  Then, the mounting operation of the component 54 to the printed wiring board 30 is started. The mounting head 130 is moved to the feeder-type component supply device 18 or the tray-type component supply device 20, and the suction nozzle 170 sucks the component 54. After the component 54 is received, the component 54 held by the mounting head 130 is imaged by the component imaging system 190 while the mounting head 130 is moved to the component mounting position of the printed wiring board 30. The obtained image data is processed by the image processing computer 238 to obtain a holding position error of the component 54. Among them, the rotational position error is corrected by rotating the mounting head 130 by the head rotating device 136, and The displacement of the center of the part 54 to be attracted by correction of the center of the part 54 to be attracted and the rotation position error of the part 54 and the horizontal position error of the part mounting position of the printed wiring board 30 are the mounting head. It is corrected by correcting the moving position of 130. The mounting head 130 mounts the component 54 on the printed wiring board 30 at the component mounting position.

  In this electronic circuit component mounting machine, when the component 54 is mounted on the printed wiring board 30, the supply number of the component 54 is counted for each of the plurality of feeders 50 and component trays 110, and each feeder 50 and component tray 110 is counted. Is remembered. In the present embodiment, the supply number of the components 54 is stored in association with each of the plurality of feeders 50 and the mounting positions of the component trays 110. Then, for each of the plurality of feeders 50 and component trays 110, whether or not the number of components 54 to be supplied is insufficient is checked. Based on the flowcharts shown in FIGS. 13 to 17, replenishment of the parts 54 for the feeder-type part supply device 18 will be described.

  In S20 of the parts shortage feeder acquisition routine shown in FIG. 13, it is determined whether or not the flag F1 is set to 1. When the flag F1 is set to 1, it stores that the mounting of the component 54 on one printed wiring board 30 is completed. The flag F1 is reset to 0 by initial setting in a basic operation program (not shown), starting of component mounting work on one printed wiring board 30, or the like. Therefore, if the component 54 is being mounted on the printed wiring board 30, the determination result in S20 is NO and S21 is executed, and whether or not the mounting of the component 54 on one printed wiring board 30 is completed. Is determined. This determination is performed based on, for example, the execution status of the component mounting program. For example, the determination is performed based on whether or not all the components 54 scheduled to be mounted are mounted on the printed wiring board 30.

  If the mounting of the component 54 on one printed wiring board 30 is not completed, the determination result in S21 is NO and the execution of the routine is terminated. When the mounting is completed, the determination result in S21 is YES, S22 is executed, and the data of the connectable feeder is deleted. The connectable feeder will be described later.

  Next, S23 is executed, and after the flag F1 is set to 1, S24 is executed, and the count value C of the counter is incremented by one. This counter counts the number of printed wiring boards 30 on which the component 54 is mounted.

  Subsequently, S25 is executed, and the number of the remaining printed wiring boards 30 on which the parts 54 are mounted, the types of the parts 54 necessary for the same (here, obtained by the component identification code), and the remaining printed wiring boards 30 The number of parts 54 required for mounting on all the feeders 50 is obtained. The remaining number of printed wiring boards 30 is obtained by subtracting the number of printed wiring boards 30 on which components 54 have been installed from the total number of components 54 to be installed. The planned number of mountings is obtained from the type of the printed wiring board 30 obtained by receiving information recorded on the tag chip 36 provided on the printed wiring board 30. The host computer 240 stores data for associating the type of the printed wiring board 30 with the planned number of sheets to be mounted. The planned number of sheets to be mounted is read, the number of the mounting completion counted in S24 is subtracted, and the remaining number The number of parts not mounted) is required. The type of component 54 required for mounting is obtained from, for example, a component mounting program. In addition, the number of components 54 required for mounting on all the remaining printed wiring boards 30 for each feeder 50 (required supply number) is the same for each feeder 50 of components 54 required for mounting on one printed wiring board 30. Is multiplied by the number of the remaining printed wiring boards 30. The number of components 54 required for mounting on one printed wiring board 30 for each feeder 50 is obtained from, for example, a component mounting program. Once the types of components 54 required for one printed wiring board 30 and the supply number for each feeder 50 are obtained, they may be stored in the RAM 224 of the mounting control computer 230 and used repeatedly. At this time, the number of supplies for each feeder 50 is stored in association with the mounting position.

  Next, S26 is executed, and the remaining component 54 is retained for each of the feeders 50 that do not form a group among the plurality of feeders 50 that are mounted on the feeder support 48 and are currently used to supply the component 54. A number is required. Whether or not the feeder 50 forms a group can be determined from, for example, a component mounting program and component mounting related data. For example, the feeder 50 that is currently used to supply the component 54 forms a group from the mounting position of the feeder 50 and the component mounting related data associated with each of all the component mounting positions in the sequence data of the component mounting program. For example, it is checked in the order of mounting the parts 54. The feeder 50 which does not form a group is memorize | stored by the mounting position, for example.

  The remaining number of parts 54 can be obtained by subtracting the supply number from the initial number of parts that is the number of parts 54 that the feeder 50 has accommodated before the start of mounting. The initial accommodation number is recorded on the tag chip 98 provided on the reel 66 as described above. When the reel 66 is set in the feeder 50, the component information and the feeder information are obtained in association with each other by reading the information of the tag chips 90 and 98, and the mounting position corresponds to the feeder information when the feeder 50 is mounted on the feeder support base 48. The non-group feeder 50 holds based on the mounting position and component information stored in association with each other from these pieces of information and the mounting position of the non-group feeder 50. The component information about the component 54 to be obtained is obtained, and the initial number of components 54 accommodated in the feeder 50 is obtained. The number of components supplied is counted for each feeder 50 in the mounting control computer 230 when the components are mounted, and the remaining number of components 54 is calculated. In addition, once the loading position of the feeder 50 that does not form a group is acquired, the information is stored and used later. On the contrary, since the feeders 50 forming the group are also known, the information of the feeders 50 may be stored and used later. If the feeder 50 is replaced, the feeder information is updated for the mounting position where the replacement has been performed, and the component information about the component 54 held by the newly mounted feeder 50 is obtained. . The component information and the feeder information may be read from the host computer 240 as necessary, and at least the feeder 50 mounted on the feeder support base 48 is supplied from the host computer 240 to the mounting control computer 230, stored, and used. May be.

  Next, S27 is executed, and a feeder 50 (hereinafter referred to as a component shortage feeder) 50 in which the component 54 is insufficient is obtained. For the parts 54 held by the feeders 50 that do not form groups, the remaining number calculated in S26 is compared with the number of parts 54 required for supply to the remaining printed wiring board 30 obtained in S25. If the number is smaller, the parts 54 are insufficient, and the feeder 50 is a parts shortage feeder. The part shortage feeder 50 is memorize | stored by the mounting position, for example. You may memorize | store based on feeder ID and may memorize | store based on a mounting position and feeder ID. Further, the remaining number of parts 54 is stored in association with the part shortage feeder 50.

  For the parts shortage feeder 50, the parts supply timing acquisition routine shown in FIG. 14 is executed. The acquisition routine for parts replenishment time and the like is also performed in a state in which the parts mounting work is not performed. When there are a plurality of component shortage feeders 50, the component supply timing acquisition routine is executed in order for each of the component shortage feeders 50. For example, an acquisition routine such as a component supply time is executed in ascending order of the mounting position number among the plurality of component shortage feeders 50. If the parts supply timing acquisition routine is executed for all of the parts shortage feeders 50, the parts supply timing acquisition routine is not executed until the mounting of the parts 54 on the printed wiring board 30 is completed.

  In S31 of this routine, it is determined whether or not the mountable number, that is, the number of printed wiring boards 30 on which the component 54 can be mounted by supplying the component 54 by the component shortage feeder 50 is equal to or less than the set number A1. . The number of mountable sheets is obtained based on the number of components 54 (obtained from the component mounting program) supplied by the component shortage feeder 50 for one printed wiring board 30 and the remaining number of components 54 in the component shortage feeder 50. .

  The set number A1 is set to a number that allows the component shortage feeder 50 to determine that the component 54 may be replenished by connecting the taping component 58. To connect the taping component 58, the operator removes the reel 66 from the feeder 50, removes the taping component 58 remaining on the reel 66 from the reel 66, and starts the taping component 58 accommodated in the new reel 66 from the reel 66. The end of the removed taping component 58 is connected, wound around the reel 66, and the new reel 66 is held by the feeder 50. Therefore, even if it is found that the parts 54 are insufficient when the number of remaining parts 54 in the feeder 50 is large, the connection work cannot be performed immediately. If the remaining length of the taping component 58 is long enough to be wound around the new reel 66 from above the new taping component 58 already wound around the new reel 66, the connection can be made and the set number A1 is reached. In the present embodiment, for example, considering the number of parts supplied to each printed wiring board 30 of each of the plurality of feeders 50, the part accommodation pitch in the taping parts 58, etc., all the feeders 50 that do not form a group. It is set in common, and the length of the taping component 58 is set to a number that allows it to be determined that the taping component 58 can be connected. This is because the length of the taping component 58 corresponds to the number of components 54 accommodated, and the number of components 54 and the number of mountable components correspond to each other, and it is determined whether the mountable number is equal to or less than the set number A1. Thus, it is determined whether or not it is time to replenish the component 54 by connecting the taping component 58. The determination result in S31 is initially NO, and the routine execution ends.

  The set number A1 is a detected value of component replenishment timing, and may be varied depending on the feeder 50. For example, when creating a component mounting program, for each feeder 50, the number of parts 54 held by the feeder 50 is set and stored in accordance with the number of taping parts 58 supplied, the number of parts accommodated, and the like. In accordance with 50, the set number A1 is read and determined. The component replenishment time detection value may be set by the remaining length of the taping component 58 or by the remaining component number, for example, instead of the number of printed wiring boards 30. The set length or the like may be common to the plurality of feeders 50 or may be different.

  If the mountable number is equal to or less than the set number A1, the determination result in S31 is YES and S32 is executed to determine whether the mountable number is equal to or less than the set number A2. The set number A2 is smaller than the set number A1, and the part shortage feeder 50 is set to a number that can determine that the remaining amount (remaining length) of the taping component 58 is insufficient to connect the taping component 58. Has been.

  The connection work of the taping component 58 is performed by the operator behind the component supply device 18 (on the side opposite to the wiring board transport device 12 side) while the feeder 50 is still attached to the feeder support base 48. Therefore, at the time of connection, it is necessary that the taping component 58 having a length sufficient for the operator to perform the connection work remains, and the set number A2 is equal to the set number A1 and is not a group. Considering the number of parts supplied per printed wiring board of each feeder 50, the part accommodation pitch, etc., the feeders 50 are set in common and the remaining amount of the parts 58 is not suitable for the connection work. It is set to a number that can be determined. When the set number A1 is smaller than the set number A2 and the mountable number is less than or equal to the set number A1, the operator can perform the tape connection work behind the component supply device 18. If the mountable number is larger than the set number A2, the determination result in S32 is NO and S33 is executed, and the feeder 50 capable of replenishing the component 54 by connecting the taping component 58, that is, the connectable feeder is, for example, , Stored according to its mounting position. Feeder information may also be stored.

  The set number A2 is a taping component connection time detection value, and may be set for each of at least one feeder 50 that does not form a group. Further, the taping component connection time detection value may be set by the remaining length of the taping component 58 or by the remaining component number, for example, instead of the number of the printed wiring boards 30. The taping component connection time detection value may be common to a plurality of feeders or may be different.

  On the other hand, if the remaining length of the taping component 58 is short and is insufficient for the connection work, the number of mountable sheets becomes equal to or less than the set number A2, the determination result of S32 becomes YES, S34 is executed, and the mounting is performed. It is determined whether or not the possible number is equal to or less than the set number A3. The set number A3 is set to be smaller than the set number A2, and is set in common to the feeders 50 in consideration of the number of parts supplied per printed wiring board of each of the at least one feeder 50 that does not form a group. In addition, the number is set to a value at which it can be determined that the component 54 may be replenished by replacing the feeder 50. When the feeder 50 is replaced, the parts 54 remaining in the feeder 50 are not used and are wasted. Therefore, the replacement is performed in a state where the number of remaining parts 54 is as small as possible before the parts 54 are used up. -ing If the mountable number is larger than the set number A3, the determination result in S34 is NO and S35 is executed. For example, the display screen indicates that the remaining number of parts 54 of the feeder 50 is small and replenishment by replacement is near. Notification is given by a display on H.254 or the like. It is foretold that the time for replacement will be near. This notification may be omitted.

  The set number A3 is a feeder replacement time detection value, and may be set for each of the plurality of feeders 50. Further, the feeder replacement time detection value may be set by the remaining length of the taping component 58, or may be set by the remaining component number, for example, instead of the number of printed wiring boards 30. The feeder replacement time detection value may be common to a plurality of feeders or may be different.

  In the present embodiment, the component replenishment time, which is the replenishment time of the component 54 by connecting the taping component 58 or replacing the feeder 50, is determined according to the mountable number of sheets, and the set number of sheets A1, A2, A3 is also For example, even if a plurality of feeders 50 that require component replenishment are generated at the same time, the number is set such that the replenishment operation can be performed with some margin.

  If the mountable number is equal to or less than the set number A3, the determination result in S34 is YES and S36 is executed to determine whether the mountable number is 0 or not. The result is YES, S37 is executed, and the mounting operation of the component 54 by the electronic circuit component mounting machine is stopped. If the number of mountable sheets is not 0, the determination result in S36 is NO and S38 is executed, and a replacement startable period, which is a period during which the replacement of the feeder 50 can be started, is calculated. Are stored in association with at least one of the mounting position. For the parts shortage feeder 50, a period during which the replacement work of the feeder 50 can be started is determined. The feeder 50 that can be mounted is equal to or less than the set number A3, but the feeder 50 that is not zero is difficult to replenish the component 54 by connecting the taping component 58, and requires replacement that requires replenishment of the component 54 by replacing the feeder 50. Feeder 50.

  It is necessary to replace the feeder 50 when the feeder 50 is not supplying the component 54. The replacement work must be started at the non-supply time and must be completed before the supply is started. In S38, the supply waiting for the component shortage feeder 50, which is a period from the completion of the supply of the component 54 to the start of the next supply, is performed. A period excluding the period corresponding to the replacement required time, which is the time required for the replacement work of the feeder 50, at the end of the supply waiting period is obtained, and is set as the replacement startable period. Thereby, it is possible to notify the replacement startable period of the parts shortage feeder 50 at an appropriate time.

  In the present embodiment, the supply standby period is a component that is mounted on the printed wiring board 30 after the feeder 50 requiring replacement has finished supplying the component 54 until the next supply is performed during an average component mounting cycle time. It is obtained by adding the time required for work related to the replacement of the printed wiring board 30 to the time obtained by multiplying the number n of 54. The average component mounting cycle time is the time required for the mounting head 130 to receive the component 54 from the component supply device 18, 20 and mount it on the printed wiring board 30 and to receive the next component 54 from the component supply device 18, 20. , The average for all parts 54 to be mounted. The number n of parts is obtained from the part mounting program, and the time required for replacement is acquired and stored in advance. The work related to the replacement of the printed wiring board 30 includes, for example, carrying out the printed wiring board 30 that has been mounted, carrying in the printed wiring board 30 on which the component 54 is next mounted, imaging the reference mark 34, and tag tag 36. Reading. As described above, in the present embodiment, the opportunity for the feeder 50 to supply the component 54 is once for one printed wiring board 30, and the time required for work related to replacement of the printed wiring board 30 is also included. Including the supply waiting period is calculated. The calculated supply standby period and replacement startable period are stored in association with information specifying the replacement-required feeder 50, for example, at least one of the feeder ID and the feeder 50 mounting position. Thus, the parts shortage feeder 50 and the mountable number of sheets are obtained based on the initial number of accommodated parts and the number of supplied parts 54 accommodated in the feeder 50, and the initial accommodated number as information recorded in the tag chip 90 is the part. Used to supply 54.

  The taping component 58 can be connected either when the component 54 is attached to the printed wiring board 30 or when it is not attached. The taping electronic circuit component connection routine shown in FIG. 15 is always executed. Moreover, this routine is collectively performed about the feeders 50, if there are a plurality of connectable feeders 50. In S41 of the taping electronic circuit component connection routine, it is determined whether or not there is a connectable feeder 50. If the part supply time acquisition routine S33 is executed and the connectable feeder 50 is acquired and stored, the determination result of S41 is YES and S42 is executed, and the connectable feeder 50 is displayed on the display screen 254. And notified. For example, the mounting position of the connectable feeder 50, the feeder ID, the component identification code of the component 54 to be held, and the like are displayed. Next, S43 is executed to determine whether or not the connection is completed. When the worker performs the connection work of the taping component 58 in accordance with the display of S42, when the work is completed, the input device 244 inputs, for example, the mounting position of the feeder 50 that has performed the connection work and the work completion. If there is a feeder 50 for which work has been completed, the determination result in S43 is YES, S44 is executed, and the feeder 50 that has been connected is erased from data indicating that it is a connectable feeder, display, and the like. When the taping component 58 is connected, the carrier tapes 56 and the cover tapes 62 of the two taping components 58 connected to each other are connected to each other. The component 58 or the tag chip 90 is accommodated in the carrier tape 56. The housing recesses are connected so as to be continuous at a constant pitch. The connection method of the taping component 58 is already known and will not be described.

  When the operator connects the taping component 58, the worker inputs the mounting position of the feeder 50 that holds the taping component 58, and uses the portable reader / writer 248 to record information recorded on the tag chip 90 accommodated in the carrier tape 56. It is read using and sent to the mounting control computer 230. The component accommodating recess 60 in which the tag chip 90 of the carrier tape 56 is accommodated is covered with a cover tape 62, but is made of a synthetic resin, so that electromagnetic waves are not blocked and information on the tag chip 90 can be read. Based on the input mounting position, the acquired component information and the component mounting data, it is confirmed whether or not the type of the component 54 held by the connected taping component 58 is to be supplied at the mounting position. Is done. The component information is sent to the host computer 240 in association with the feeder information, and is stored in place of the feeder information and the component information stored in association with each other for the same feeder 50. Further, the number of component supplies stored corresponding to the mounting position is reset to zero. Therefore, as a result of calculation of the remaining number of parts in the feeder 50 in S26 of the parts shortage feeder acquisition routine, it is avoided that the connected feeder 50 is made a parts shortage feeder in S27. As will be described later, the number of component supplies is reset when information recorded in the memory is received in a state where the tag chip 90 is located in the component supply unit. After the connection, the supply number of the parts 54 remaining in the taping parts 58 that are actually supplying the parts 54 is counted. If the loading position of the feeder 50 is input when the taping component 58 is connected, the execution of the connection is stored in association with the mounting position. Further, the number of remaining parts and the number of parts supplied at the time of connection completion input are stored. Thereby, for example, even if a series of mounting operations are completed before the tag chip 90 reaches the component supply unit, the execution of the connection is stored, the remaining number of components when the connection completion is input, and the number of component supplies And the component supply number in the feeder 50 is obtained from the component supply number after the connection is completed. The remaining number of parts and the like are detected when the tag chip 90 reaches the part supply unit and is deleted when the connection part of the taping part 58 is detected. The number of parts supplied is not reset at the time of connection completion input, and the number of parts supplied at that time is memorized. After that, the number of parts supplied is compared with the initial capacity every time a part is supplied, and the tag chip 90 reaches the part supply unit. You may make it detect whether it did. At this time, when the tag chip 90 reaches the component supply unit, the number of component supplies is reset to zero. In addition, the storage of connection completion avoids being a parts shortage feeder.

  Based on the feeder replacement routine shown in FIG. 16, the replenishment of the parts 54 by replacing the feeder 50 will be described. If a replacement feeder is required and a replacement startable period is determined, a feeder replacement routine is executed. This routine is executed separately for each of the replacement feeders 50 for which the feeder replacement startable period has been acquired in S38 of the parts supply time etc. acquisition routine. In the present embodiment, a plurality of feeder replacement routines are provided. This routine is performed during the mounting operation of the component 54 to the printed wiring board 30 and during non-working. The plurality of feeder replacement routines are all configured in the same manner, and one of them will be described as a representative.

  First, in S51, it is determined whether or not the flag F2 is set. The flag F2 is set to store that the feeder replacement operation has been started. If the replacement work has not been started and the flag F2 has been reset, the determination result in S51 is NO, S52 is executed, and it is determined whether the flag F3 is set. By setting the flag F3, it is stored that the supply of the component 54 to one printed wiring board 30 by the feeder 50 requiring replacement has been completed.

  If the flag F3 has been reset, the determination result in S52 is NO, S53 is executed, and it is determined whether or not component supply by the feeder 50 requiring replacement has been started. This determination is made based on the execution status of the component mounting program. If the supply of components by the replacement feeder 50 is started, the determination result of S53 is YES and S54 is executed. It is determined whether the supply has ended. Until the supply ends, the determination result in S54 is NO, and the execution of the routine ends.

  If the supply of the component 54 to one printed wiring board 30 by the replacement feeder 50 is completed, the determination result in S54 is YES, and after the flag F3 is set in S55, S56 is executed and S38 is executed first. Is displayed on the display screen 254, which represents the exchange startable period calculated in. The displayed time is reduced over time. The display screen 254 also displays the number, type, loading position, and type of the component 54 held in the feeder 50, which is the feeder ID of the feeder 50 requiring replacement, and the operator can start replacement by viewing this display. If the period remains, the replacement of the feeder 50 can be started, and if the period becomes zero, the replacement work cannot be started.

  Next, S57 is executed, and it is determined whether or not T1 time has elapsed. The T1 time represents the exchange startable period, and the elapse of the exchange startable period can be known from the passage of the T1 time. The determination result of S57 is NO until the time T1 elapses, and it is determined whether S58 is executed and the exchange is started. This determination is made based on, for example, whether the feeder 50 has been removed from the feeder support base 48. This determination is made based on the detection signal of the feeder detection device 246. If the feeder 50 is detected by the feeder detection device 246, the feeder 50 has not been removed from the feeder support base 48, and the replacement has not started, the determination result in S58 is NO and the execution of the routine ends. Since the flag F3 is set to 1, the next time S52 is executed, the determination result is YES, S53 to S55 are skipped, and S56 is executed.

  If the replacement of the feeder 50 is started before the time T1 elapses, the determination result in S58 is YES, S59 is executed, the flag F2 is set, and the flag F3 is reset. On the display screen 254, the feeder ID, mounting position, type, and the like of the feeder 50 requiring replacement are displayed along with the time indicating the replacement startable period, so that the operator can see the feeder 50 that needs to be replaced. The feeder support base 48 is removed, and another feeder 50, which is a new reel 66 containing the same type of component 54, is attached to the feeder support base 48. At this time, as in the case of the setup change, the mounting position is input, and the information recorded in the tag chip 98 provided in the feeder 50 is received by the portable reader / writer 248 and sent to the attachment control computer 230 for exchange. It is confirmed whether or not the type of the component 54 held in the feeder 50 matches the type set for supply at the mounting position. Further, from the feeder information stored for the newly loaded feeder 50, the component information about the component 54 accommodated in the feeder 50 is obtained, and the initial accommodation number and the like are obtained.

  By setting the flag F2, the next time S51 is executed, the determination result is YES, S60 is executed, and it is determined whether or not the exchange is completed. If the replacement of the feeder 50 is completed, the operator inputs the replacement completion using the input device 244. If the replacement is not completed, the determination result in S60 is NO, S61 is executed, and the time T2 is set. It is determined whether or not it has elapsed. The time T2 represents the supply standby period. If the time T2 has not elapsed, the determination result in S61 is NO. The determination of completion of replacement may be performed by detecting the feeder 50 by the feeder detection device 246, for example. In this case, the feeder detection device 246 and the like constitute an exchange completion detection unit.

  If the replacement of the feeder 50 is completed before the time T2 elapses, the determination result in S60 is YES, S62 is executed, the feeder replacement data is deleted, and the flag F2 is reset. The feeder replacement data is at least one of the feeder ID (number) and the mounting position of the feeder 50 requiring replacement, a replacement startable period, and the like, and is data stored in S38 of the parts supply time acquisition routine. This data erasure eliminates the replacement feeder 50 and the feeder replacement routine is not executed. Further, the supply number of the parts 54 by the feeder 50 is reset to 0 based on the completion of the replacement. The count value of the counter provided corresponding to the mounting position is reset.

  If the replacement of the feeder 50 is started but is not completed before the time T2 elapses, the determination result in S61 is YES, S63 is executed, and the mounting operation of the component 54 by the electronic circuit component mounting machine is stopped. It is done. Further, the cause of the stop is displayed on the display screen 254 and notified.

  If the T1 time has elapsed without starting the feeder replacement, that is, if the replacement startable period has elapsed, the determination result in S57 becomes YES, S64 is executed, and the flag F3 is reset. Therefore, the determination result of S51 to S53 is NO until the next supply of the parts requiring replacement 50 is started. In addition, when the replacement startable period elapses without starting the replacement work of the feeder 50, it is displayed and notified that the replacement is impossible until the next replacement is possible. You may do it. An alarm may be issued. In this case, the part which notifies that it is the non-exchangeable period of the control apparatus 24 comprises a non-exchangeable period alerting | reporting part.

  In this way, the parts shortage feeder 50 is acquired for the feeders 50 that do not form a group, and the parts 54 are supplied by connecting the taping parts 58 or replacing the feeders 50. On the other hand, for the feeders 50 forming the group, if the next device function is executed and the parts 54 are still insufficient, the parts 54 are replenished by executing the next designation instruction routine shown in FIG. Yes.

  In the present embodiment, the next designation instruction routine is executed during the non-mounting operation of the component 54. In the present embodiment, all the feeders 50 that are actually used to supply the parts 54 are executed one by one in order, for example, in ascending order of mounting position numbers on the feeder support base 48. It may be executed in the order in which the components 54 are mounted. The feeder 50 that is actually used to supply the component 54 is obtained from, for example, a component mounting program. In addition to the next designation instruction routine, there is provided a routine for detecting the feeder 50 that is currently used to supply the component 54 and forms a group, and the next designation instruction routine for the feeder 50 detected thereby is provided. May be executed. Further, the next designation instruction routine may be performed during the mounting operation of the component 54 on one printed wiring board 30.

  In S71 of the next designation instruction routine, first, it is determined whether or not the feeder 50 is a grouped feeder 50. The feeders 50 forming the group are acquired based on the component mounting program, the component mounting related data, and the like, similar to the case where the feeder 50 that does not form the group is acquired in S26 of the component shortage feeder acquisition routine. If the feeder 50 is not a group of feeders 50, the determination result in S71 is NO and the execution of the routine ends.

  If the feeder 50 is a feeder 50 that forms a group, the determination result of S71 is YES, and S72 is executed. It is determined whether or not the feeder 50 is used. This determination is performed based on the mounting position of the feeder 50 and the component mounting related data. It is determined whether or not the supply order set in the component mounting related data is the last for the mounting positions of the feeders 50 determined to form a group. If not, the determination result in S72 is NO. The routine execution ends.

  For the feeders 50 forming a group, the parts 54 are removed from the feeder 50 until the remaining number becomes zero. For example, when the mounting head 130 takes out the component 54 and the component 54 cannot be received from the same feeder 50 a plurality of times, for example, twice, if the component 54 is lost, The parts 54 are received from the feeder 50 in the next order. A feeder 50 that is in the same group as the feeder 50 and that is later in the order of supply than the feeder 50 in which the component is cut off is obtained from the mounting position of the feeder 50 that has caused the component cut and the component mounting related data. Next, the feeder 50 that supplies the component 54 is used. In the component mounting program, the mounting position of the feeder 50 that is associated with the component mounting position is replaced by the feeder 50 that supplies the component 54 instead of the feeder 50 that is out of components. It is rewritten to the mounting position.

  Further, for the feeders 50 that form a group, since the parts 54 are supplied until the parts run out, the parts 54 are replenished by replacing the feeders 50, but are replenished by connecting the taping parts 58. May be. In this case, as with the feeder 50 that does not form a group, for example, it may be informed that it is the replenishment time due to the connection of the taping component 58 based on the number of mountable sheets. However, in the case of the feeders 50 forming a group, the taping component 58 is not connected even though it is notified that the feeder is a connectable feeder, and the number of mountable sheets by supplying the component 54 of the feeder 50 becomes zero. However, the operation of the electronic circuit component mounting machine is not stopped, and the next sequential feeder 50 in the same group supplies the components 54.

  If the feeder 50 is the last feeder 50 in the group, the determination result in S72 is YES, S73 is executed, and the remaining number of parts 54 in the feeder 50 is calculated. This calculation is performed in the same manner as S26 of the parts shortage feeder acquisition routine. Next, S74 is executed, and it is determined whether or not the part 54 is insufficient. This determination is based on the remaining number of components mounted on the printed wiring board 30 acquired in S25 of the component shortage feeder acquisition routine, the number of components 54 supplied per printed wiring board for each feeder 50, and the remaining components in the feeder 50. If the remaining number is greater than the required supply number and the number of parts 54 is not insufficient, the determination result in S74 is NO and the execution of the routine ends.

  On the other hand, if the parts 54 are insufficient, the determination result in S74 is YES, S75 is executed, and the next designation instruction is displayed on the display screen 254. When the feeders 50 belong to the same group as the last feeder 50 and the feeders 50 other than the last feeder 50 in the supply order finish supplying the parts 54 respectively held, the group Of these, an instruction to specify the component to be supplied next is displayed on the display screen 254. All feeders 50 other than the last in the supply order belong to the group formed by the feeders 50 lacking the parts 54, that is, the feeder positions, feeder IDs, supply orders, and supply parts 54 of all the feeders 50 that are out of parts. The type is also displayed.

  The operator determines the feeder 50 to which the component 54 is to be supplied next in accordance with the next designation instruction or the like, and inputs the feeder 50 using the input device 244. This designation is performed, for example, by designating the mounting position of the feeder 50 on the feeder support base 48. In the present embodiment, the parts 54 are supplied to the feeders 50 belonging to the group until the remaining number of parts 54 becomes zero. Therefore, the operator designates the feeder 50 that supplies the component 54 next by the mounting position, and replaces the feeder 50 mounted at the mounting position to replenish the component 54. At this time, the worker exchanges all or some of the feeders 50 other than the feeder 50 whose supply order is the last among the plurality of feeders 50 forming a group, and designates the supply order. The designation of the supply order is performed even if there is only one replaced feeder 50, and the mounting position and the supply order in which the feeder 50 is replaced are input, and the input supply order is stored as component mounting related data. If the supply order stored corresponding to the mounting position is different from the currently stored supply order, the data is rewritten. The operator also inputs the next designation completion when the parts replenishment is completed.

  Then, if a part outage occurs in the last feeder 50 among the plurality of feeders 50 forming the group, another feeder 50 forming the same group supplies the parts 54 according to the newly stored supply order. When the replacement is performed for only some of the feeders 50 and the supply order is specified for only some of the feeders 50, the feeder 50 and the mounting position where the feeder 50 other than the last feeder 50 is mounted is mounted. The supply order associated with is deleted.

  Note that among the feeders 50 that form a group, the feeders 50 whose supply order is other than the last may be replaced even if the feeder 50 whose supply order is last is not in a component shortage state. . For example, if a part of the group of feeders 50 is cut out and the feeder 50 is not supplied last, the information about the feeder 50, the mounting position, the information about the parts 54 to be accommodated, etc. are displayed on the display screen 254. It is informed that the exchange is possible. Alternatively, the operator may find and replace the feeder 50 that is out of parts. The order of supply may also be entered. In this case, S75 is executed in the next designation instruction routine, and the replenishment of the part 54 may be completed before the next designation display is displayed. In this case, the operator can, for example, replace the feeder 50 with a part. The next designation completion such as the completion of replenishment 54, the supply order or the supply order designation completion is input.

  In any case, when the feeder 50 is replaced, the loading position is input and information recorded on the tag chip 98 of the feeder 50 is received, and the type of the component 54 is confirmed. Then, the feeder information associated with the mounting position is rewritten with the newly read information of the tag chip 98. As a result, a new initial number of components 54 can be obtained for the feeder 50 newly mounted on the feeder support base 48. In addition, the count value of a counter which is provided in association with the exchanged mounting position of the feeder 50 and counts the number of parts supplied is reset to zero.

  Although description using the flowchart is omitted, the component 54 is taken out from the designated feeder 50 in accordance with the next designation. If no designation is made, the electronic circuit component mounting machine is stopped due to the out of components in the feeder 50 in the last supply order among the feeders 50 forming a group.

  When the feeder 50 is replaced and the supply order is input, if the data with the last supply order is set for one of the replaced at least one feeder 50, the next designation instruction routine for that feeder 50 is set. Is executed, the determination in S72 is YES, a next designation instruction is displayed, and the parts 54 are further replenished by replacing the feeder 50. After the next designation, if there is no feeder 50 whose supply order is greater than the supply order of the feeder 50 that is currently supplying the part 54 (the supply order is later), the feeder 50 that is currently supplying the part 54 is the last feeder. It may be.

  As described above, in the new taping component 58, the tag chip 90 is accommodated in the component accommodating recess 60 at the tip. Therefore, when the component 54 is replenished by the connection of the taping component 58, the tag chip 90 accommodated in the new taping component 58 connected to the taping component 58 that is actually supplying the component 54 is sent as the taping component 58 is sent. It is necessary to prevent the printed circuit board 30 from being mounted on the component supply unit.

  Therefore, when the completion of connection is input when the taping component 58 is connected, the component information associated with the feeder information in the host computer 240 is the information recorded in the tag chip 90 accommodated in the new taping component 58. In addition, the remaining number of components 54 at the time of connection completion input, that is, the remaining number of components 54 in the taping component 58 that is currently supplying the components 54 is acquired and stored. Is done.

  Based on the remaining number of the parts 54, an approximate supply number of the parts 54 until the tag chip 90 reaches the part supply unit can be obtained. The connection part of the taping component 58 is detected by the connection part detection device, the number of parts 54 positioned between the connection part detection position and the part supply part is acquired, and the part 54 until the tag chip 90 reaches the part supply part. May be obtained.

  Each time the component 54 is supplied, it is monitored whether or not the supply number of the component 54 after the connection completion input of the taping component 58 has reached the estimated number that the tag chip 90 has reached the component supply unit. When approaching, when the mounting head 130 receives the component 54 from the feeder 50, the movement path of the mounting head 130 so that the reader / writer 200 passes over the component receiving recess 60 located in the opening 84 of the cover 80. Is set.

  In the present embodiment, the mounting head 130 and the reader / writer 200 are provided side by side in the Y-axis direction, and the feeder 50 is provided side by side in the X-axis direction. In the vicinity of the feeder 50, the mounting head 130 is provided. If the reader / writer 200 is moved in a direction parallel to the Y-axis direction (longitudinal direction of the feeder 50) with the position in the X-axis direction aligned with the feeder 50, and the tag chip 90 is in the opening 84, The reader / writer 200 can receive information through communication. The reader / writer 200 performs reception while moving. The reader / writer 200 is moved to the lower end position at the time of reception. The tape is lowered to a distance at which there is no fear of wireless communication with the tag chip 90 of the taping component 58 held in the adjacent or adjacent feeder 50, and is held by the taping component 58 of the feeder 50 from which the component 54 is to be taken out. Communication is performed only with the tag chip 90.

  As described above, the taping component 58 is covered with the metal cover 80, and the tag chip 90 does not reach the opening 84 but is positioned upstream of the component supply unit in the carrier tape feeding direction and is covered with the cover 80. In this state, information is not read by the reader / writer 200, and it is not erroneously determined that the tag chip 90 is located in the opening 84.

  If communication is not performed, the component 54 is accommodated in the component accommodating recess 60 located in the opening 84, and the mounting head 130 takes out the component 54. If communication is performed, the tag chip 90 is in the opening 84, and the taping component 58 is fed at a set pitch by the carrier tape feeding device 72 based on the detection of the tag chip 90. This pitch is set to a pitch that ensures that the tag chip 90 is retracted from the opening 84 and the component receiving recess 60 in which the component 54 is stored is located in the opening 84. After feeding, the mounting head 130 takes out the component 54. In addition, by acquiring component information by communication with the tag chip 90 located in the opening 84, for example, the type of the component 54 can be confirmed again. As described above, the information recorded in the tag chip 60 at the time of connecting the taping component 58 is acquired using the portable reader / writer 248, and the type of the component 54 is confirmed. For example, the operator forgets the confirmation. But you can check here.

  In this way, by feeding the taping component 58 based on the detection of the tag chip 90, it is avoided that the tag chip 90 is taken out from the carrier tape 56 by the mounting head 130 and mounted on the printed wiring board 30. Further, it is determined whether or not the tag chip 90 is erroneously taken out based on the imaging data of the component 54 by the component imaging system 190. As described above, in this embodiment, the tag chip holder 92 has a cross-sectional shape that is clearly different from the component 54, and the shape of the image obtained by imaging is the same as the cross-sectional shape of the tag chip holder 92. If the shape is the same, it is assumed that the tag chip 90 has been taken out, and is discharged to a discharge device (not shown), and the component 54 is taken out from the feeder 50 again. The detection of the tag chip 90 based on the reading of the information of the tag chip 90 and the imaging is performed only at the time when it is estimated that the tag chip 90 is located in the component supply unit due to the connection of the taping component 58. If the tag chip 90 is detected, the supply number of the parts 54 in the feeder 50 is reset to zero. Further, information indicating that the taping component 58 has been connected, the remaining number of components, and the number of components supplied at the time of connection completion input are deleted.

  Although description is omitted, the supply of the component 54 in the tray-type component supply device 20 is performed by replacing the component tray 110 in this embodiment, and if there is a grouped component tray 110, the next designation is performed. These replacement and next designation are performed in the same manner as the feeder-type component supply device 18.

The use of suction nozzle information recorded on the tag chip 180 provided on the suction nozzle 170 will be described in detail.
The suction nozzle information is used as follows in the present embodiment. (a) Acquisition of the suction nozzle 170 existing in the electronic circuit component mounting machine, (b) Acquisition of the suction nozzle 170 accommodated in the nozzle stocker 186, (c) Creation of production history information, (d) Assembly of the electronic circuit (E) Prohibition of use of an unusable suction nozzle 170, (f) Guidance for performing maintenance on the suction nozzle 170, (g) Notification of a possible nozzle, ( h) The suction nozzle 170 is used for assisting the housing operation in the nozzle stocker 186.

Further, the suction nozzle information is used at the time of production preparation, at the start of production, during production, and at least once after production. Hereinafter, utilization of the suction nozzle information at each time will be described.
In the electronic circuit component mounting machine, the production is performed by mounting the component 54 on one type of printed wiring board 30 with respect to a predetermined number of printed wiring boards 30. The suction nozzle 170 corresponding to the type of the printed wiring board 30 to be mounted, that is, the nozzle stocker 186 in which the suction nozzle 170 corresponding to the type and number of the parts 54 to be mounted on the printed wiring board 30 is accommodated is attached to the stocker mounting portion 280. . The suction nozzle 170 is set together with the nozzle stocker 186 according to the type of the printed wiring board 30.

  If the nozzle stocker 186 is actually attached to the stocker attachment portion 280, it is removed from the stocker attachment portion 280. The nozzle stocker 186 is a nozzle stocker 186 that houses the suction nozzle 170 used for mounting the component 54 on the printed wiring board 30 that has been produced, and the suction nozzle 170 held by the mounting head 130 becomes the nozzle stocker 186 After being returned, it is removed.

  In principle, the suction nozzle 170 held by the mounting head 130 is returned to the nozzle holding hole 284 in which it is accommodated. At this time, the presence or absence of the suction nozzle 170 in the nozzle holding hole 284 is confirmed. This confirmation is always performed when the suction nozzle 170 is returned to the nozzle stocker 186 and accommodated. It is confirmed whether or not the nozzle holding hole 284 is empty, and interference and damage between the suction nozzles 170 are avoided. In the state where the nozzle presence / absence sensor 330 is set by the XY robot 132 to the nozzle presence / absence detection position preset for the nozzle holding hole 284, that is, the separation preventing member 286 is located at the separation preventing position, the separation preventing member 286 of the nozzle holding hole 284 is used. The uncovered portion is moved to a position where light is irradiated, and light is irradiated to detect the presence or absence of the suction nozzle 170. The nozzle presence / absence detection position is a plurality of nozzle holding holes 284 of the nozzle stocker 186, and is set in advance for each of the nozzle accommodating portions and recorded in the tag chip 320, and is recorded in the tag chip 320 when the nozzle stocker 186 is attached. The received stocker information is obtained together with the nozzle accommodating position and the like.

  If the nozzle holding hole 284 is empty, the suction nozzle 170 is accommodated in the nozzle holding hole 284 and returned. Although detailed description of holding and releasing the suction nozzle 170 by the nozzle holder 168 is omitted, as described in Japanese Patent Application Laid-Open No. 11-220294, the nozzle holder 168 includes a nozzle holder 168 and a nozzle holding member 282. This is performed by a combination of relative movement in the axial direction and prevention and release of the suction nozzle 170 by the prevention member 286.

  The suction nozzle 170 is returned to a phase when the suction nozzle 170 is taken out from the nozzle holding hole 284 and in which the phases of the engagement recess 270 and the positioning pin 285 coincide with each other. The phase at the time of extraction is stored, for example, as a value of an encoder that detects the cumulative rotation angle (rotation angle) of the head rotating device 136. Therefore, when the suction nozzle 170 is lowered and accommodated in the nozzle holding hole 284, the positioning pin 285 is fitted into the engagement recess 270, and the suction nozzle 170 is accommodated in the nozzle holding hole 284 with a constant phase and detached. Even when the prevention member 286 prevents the suction nozzle 170 from being detached at the separation prevention position, the tag chip 180 is not covered by the separation prevention member 286, and information can be received and written by the reader / writer 200.

  If the suction nozzle 170 is already stored in the nozzle holding hole 284, for example, whether there is another nozzle holding hole 284 that is scheduled to be empty in the nozzle stocker 186 based on the nozzle storage information. If there is a nozzle holding hole 284 that is scheduled to be empty, and if it is actually empty, the suction nozzle 170 is accommodated in the nozzle holding hole 284. If there is no nozzle holding hole 284 in the nozzle accommodation information, a message to that effect is displayed on the display screen 254 to notify the operator. The presence or absence of the suction nozzle 170 is detected for all the nozzle holding holes 284 of the nozzle stocker 186, and an empty nozzle holding hole 284 is searched. Also good. When the suction nozzle 170 is returned to the nozzle stocker 186, the confirmation of the presence or absence of the suction nozzle 170 in the nozzle holding hole 284, and the processing based on the result, the suction nozzle 170 held by the mounting head 130 for the change of the stage is set as the nozzle. The same operation is performed when the suction nozzle 170 is returned to the nozzle stocker 186 except when returning to the stocker 186. In some cases, it is not necessary to check whether or not the suction nozzle 170 is present. In this case, the suction nozzle 170 is received in the nozzle holding hole 284 without detecting the suction nozzle 170 in the nozzle holding hole 284. The nozzle accommodation information will be described next.

  The type and number of the suction nozzles 170 necessary for mounting the component 54 are set in advance according to the type of the printed wiring board 30 and are displayed on the display screen 265. 186. The operator arbitrarily stores the suction nozzle 170 in the plurality of nozzle holding holes 284 of the nozzle stocker 186, but stores the suction nozzle 170 so that the phase becomes a preset phase. Since the separation preventing member 286 is kept in the release position and is accommodated so that the positioning pin 285 provided in the nozzle holding hole 284 can be fitted in the engaging recess 270 provided in the background forming plate 176. is there. In the present embodiment, the suction nozzles 170 necessary for mounting the component 54 are accommodated in the nozzle stocker 186 in a plurality of sets, for example, two sets. At the time of use, a part of the suction nozzles 170 are set as standby nozzles in preparation for use. It is not essential to set a plurality of suction nozzles 170, and only one set may be accommodated. Alternatively, one suction nozzle 170 of the same type as the suction nozzle 170 used for mounting may be accommodated as a spare nozzle.

  The host computer 240 may display the suction nozzle information stored in the suction nozzle information storage unit of the database 262 on the display screen 265 so that the accommodation operation is supported. For example, when there are a plurality of suction nozzles 170 of the same type, the operator determines which one of them should be accommodated in the nozzle stocker 186 and used based on the suction nozzle information. For example, the suction nozzle 170 to be used can be determined according to the number of times of suction, or the suction nozzle 170 having a lower number of suction mistakes and fewer image processing errors can be used with priority. The portion of the host computer 240 that displays the suction nozzle information on the display screen 265 constitutes a nozzle accommodation work support unit that is a kind of information use unit. The nozzle stocker 186 accommodates the suction nozzle 170 in preparation for the setup change, and the operator changes the nozzle stocker 186 in accordance with the setup change instruction.

  After the replacement of the nozzle stocker 186, the reader / writer 200 is moved by the XY robot 132 and lowered to the lower end position, and the information recorded on the tag chip 320 provided in the nozzle stocker 186 is received, and the stocker attachment section Stocker information about the nozzle stocker 186 attached to 280 is obtained. Based on this information, the nozzle stocker 186 determines whether the type is for the next printed wiring board to be produced, and the type is set according to the type of the printed wiring board 30 in the component mounting program. If it is not compatible with the type of nozzle stocker 186, it may be notified and replaced.

  If the nozzle stocker 186 is attached to the nozzle attachment portion 280, the suction nozzle 170 accommodated in the nozzle stocker 186 is examined. The reader / writer 200 is moved to the nozzle stocker 186 by the XY robot 132 and lowered to the lower end position, and information recorded on the tag chip 180 of the suction nozzle 170 is received.

  The information receiving / writing position is set for each of the plurality of nozzle accommodating portions of the nozzle stocker 186. As described above, the tag chip 180 is provided on the background forming plate 176 at a position where the radial distance from the nozzle axis is set in advance and the phase with respect to the engagement recess 270 is set in advance. In addition, since the suction nozzle 170 is phased by the phasing device and is accommodated in the nozzle holding hole 284 with a constant phase, the position of the tag chip 180 in the state where the suction nozzle 170 is accommodated in the nozzle holding hole 284 is the nozzle. It is obtained for each holding hole 284 and is set as an information receiving / writing position. The reader / writer 200 is moved to the information receiving / writing position for all the nozzle holding holes 284 and receives the information recorded in the tag chip 180. The information receiving / writing position is an information receiving / recording position, an information acquisition / writing position, or a communication position.

  When the suction nozzle information is received by communication with the tag chip 180 of the reader / writer 200, it is stored in the nozzle accommodation information memory provided in the RAM 224 in association with the nozzle accommodation position that is the position of the nozzle holding hole 284 in the nozzle stocker 186. Be made. The nozzle housing position in this case may be a coordinate value that defines the nozzle housing position, and nozzle housing portion identification information or nozzle housing portion identification information associated with the coordinate value on a one-to-one basis, for example, identification such as an identification number It can be a code. If no information is obtained from the tag chip 180 even if the information is moved to the information receiving / writing position, for example, the suction nozzle 170 is not accommodated in the nozzle holding hole 284. Alternatively, the suction nozzle 170 is accommodated in the nozzle holding hole 284, but the position where the tag chip 180 is provided may be wrong. Therefore, the presence / absence of the suction nozzle 170 is detected by the nozzle presence / absence sensor 330. If the suction nozzle 170 is stored, the storage of the suction nozzle 170 with the wrong position of the tag chip 180 and the storage position of the suction nozzle 170 are displayed. And notified. Accordingly, the operator checks the instructed accommodation position, performs appropriate processing such as exchanging the suction nozzle 170, and obtains information about the suction nozzle 170 by communicating with the tag chip 180 again for the accommodation position. The accommodation information about the accommodation position is obtained. Further, when the suction nozzle 170 is not detected by the nozzle presence / absence sensor 330 and the suction nozzle 170 is not stored in the nozzle holding hole 284, information to that effect is stored in association with the nozzle storage position.

  By the communication with the tag chip 180, the suction nozzle information recorded on the tag chip 180 is obtained, and the suction nozzle information and the nozzle storage position are associated with each other as nozzle storage information and stored in the nozzle storage information memory of the RAM 224. Nozzle accommodation information is created. The fact that the suction nozzle 170 is not accommodated in the nozzle holding hole 284 is also nozzle accommodation information. At this time, the mounting head 130 does not hold the suction nozzle 170 yet, and suction nozzle information associated with the nozzle storage positions can be obtained for all the suction nozzles 170 stored in the nozzle stocker 186 in advance. Acquisition of the suction nozzle 170 existing in the electronic circuit component mounting machine and acquisition of the suction nozzle 170 accommodated in the nozzle stocker 186 are performed. Prior to communication with the tag chip 180, the presence / absence of the suction nozzle 170 is detected by the nozzle presence / absence sensor 330, and when the suction nozzle 170 is detected, the reader / writer 200 may communicate with the tag chip 180. Good.

  If the nozzle accommodation information is obtained, it is determined whether or not the bending amount of the adsorption tube 174 and the luminance of the background forming plate 176 are measured for all the accommodated adsorption nozzles 170. The luminance of the background forming plate 176 is measured when the suction nozzle 170 is of a type that functions as a light emitter. The determination is made based on whether the amount of bending and the luminance are recorded in the suction nozzle information, and whether the difference between the recording date and the current time is within the set time. If the suction nozzle 170 is of a type in which the background forming plate 176 does not function as a light emitter, only the amount of bending of the suction tube 174 is recorded, and the difference between the recording date and time and the current time may be within a set time. . Which type of suction nozzle 170 is used can be known from the suction nozzle information.

  This determination is performed according to the adsorption tube bending amount / luminance luminance measurement presence / absence display routine shown in FIG. 21, and is sequentially performed in the order of accommodation set in advance for all the adsorption nozzles 170 accommodated in the nozzle stocker 186. First, in S <b> 81, it is determined whether or not the suction nozzle 170 is a device in which the background forming plate 176 functions as a light emitter.

  If the background forming plate 176 is the suction nozzle 170 functioning as a light emitter, the determination result in S81 is YES, S82 is executed, and whether or not the bending amount of the suction tube 174 and the luminance of the light emitter are measured. The determination is made as described above. In the present embodiment, as will be described later, when the amount of bending of the adsorption tube 174 is measured, the luminance of the light emitter is also measured. Therefore, either the amount of bending or the luminance is measured, or neither is measured.

  If both are measured, the determination result in S82 is YES, S84 is executed, and it is determined whether or not the amount of bending is measured for all the suction nozzles 170 accommodated in the nozzle stocker 186. It is determined whether it has been done. Until all the determinations are made, the determination result in S84 is NO and the execution of the routine ends.

  On the other hand, if neither the amount of bending nor the luminance is measured, the determination result in S82 is NO and S83 is executed, and the unmeasured nozzle information, for example, the serial number of the suction nozzle 170 and the nozzle housing position are stored in the RAM 224. It is stored in an unmeasured nozzle storage unit provided.

  If the suction nozzle 170 is not such that the background forming plate 176 functions as a light emitter, the determination result in S81 is NO and S86 is executed to determine whether or not the amount of bending is measured. This determination is performed as described above, and if it is measured, the determination result in S86 is YES and S84 is executed. If the amount of bending is not measured, the determination result in S86 is NO, S83 is executed, and unmeasured nozzle information is stored.

  If it is determined whether the bending amount or the like has been measured for all the suction nozzles 170 accommodated in the nozzle stocker 186, the determination result in S84 is YES, and S85 is executed. Is displayed. If unmeasured nozzle data is stored in the unmeasured nozzle storage unit, the unmeasured nozzle information is displayed. For example, the serial number of the unmeasured nozzle and the nozzle storage position are displayed on the display screen 254, and are displayed to the operator. Informed. If there is no unmeasured nozzle, this is displayed and the operator is notified. Further, it may be notified by an audio device.

  If the display screen 254 displays a serial number or the like of the suction nozzle 170 for which the suction tube bending amount and the luminous body luminance are not measured or the suction nozzle 170 for which the suction tube bending amount has not been measured, the operator sees it. Then, the serial number of the suction nozzle 170 for measuring the suction pipe bending amount and the like and the measurement instruction are input using the input device 244.

  In this electronic circuit component mounting machine, when a measurement instruction such as the amount of adsorption tube bending is given, an adsorption tube bending amount / luminance luminance measurement routine shown in FIG. 22 is executed to perform measurement. The measurement is sequentially performed on at least one suction nozzle 170 instructed by the operator. First, in S91, it is determined whether or not only the bending amount is to be measured. It is determined whether or not the suction nozzle 170 to be measured is a suction nozzle in which the background forming plate 176 does not function as a light emitter. If the background forming plate 176 functions as a light emitter, the determination result in S91. Is NO, S92 is executed, and the amount of bending of the adsorption tube and the luminance of the light emitter are measured.

  These measurements are performed as follows. First, the mounting head 130 is moved by the XY robot 132 to the nozzle storage position of the nozzle stocker 186 where the measurement is instructed, and the suction nozzle 170 is held.

  The amount of bending of the suction tube 174 is measured, for example, by imaging the suction end surface, which is the front end surface of the suction tube 174, with a component camera of the component imaging system 190, as described in Japanese Patent Laid-Open No. 2002-368589. The For example, the suction nozzle 170 is moved to the component imaging position, and the suction end surfaces are imaged at a plurality of, for example, two imaging positions with different positions around the nozzle rotation axis. At the time of imaging, the background forming plate 176 as a light emitter is caused to emit light, and the component 54 is irradiated with light, so that a projected image of the component 54 is formed. The obtained imaging data is subjected to image processing by the image processing computer 238, and the position of the nozzle rotation axis on the imaging surface is acquired from the two images of the suction end face and the two imaging positions. The amount of displacement of the suction pipe 174, which is the amount of positional deviation of the suction end face with respect to the nozzle rotation axis, from the center position of the suction end face image at the imaging position is acquired. The two imaging positions are, for example, positions separated by 180 degrees around the nozzle rotation axis.

  Further, the luminance of the illuminant is measured based on an image of the illuminant obtained at the time of imaging the suction end face. A portion obtained by removing the image of the suction end face and the image of the outer peripheral portion of the background forming plate 176 from the image of the illuminator, and a predetermined detection area, for example, an annular detection area centering on the nozzle rotation axis The average value or standard deviation of the luminance for each pixel is obtained. These average values or standard deviations are obtained based on the image data acquired at each of the two imaging positions, and the average value thereof is obtained as the luminance of the light emitter.

  After the measurement, S93 is executed, and the data obtained by the measurement is recorded on the tag chip 180. Therefore, the suction nozzle 170 for which the measurement has been completed is returned to the nozzle stocker 186. As described above, the suction nozzle 170 is returned to the nozzle holding hole 284 from which the suction nozzle 170 is taken out, and it is necessary to check whether the nozzle holding hole 284 is empty prior to the return. Based on this, interference and damage between the suction nozzles 170 are avoided. Further, the suction nozzle 170 is returned in the phase set in advance and at the time of taking out.

  After the suction nozzle 170 is housed in the nozzle stocker 186, the reader / writer 200 is moved to the information receiving / writing position set for the suction nozzle 170, communicates with the tag chip 180, and stores the measurement result and the measurement date and time. Let me write.

  If the suction nozzle 170 for which the measurement is instructed is the suction nozzle 170 in which the background forming plate 176 does not function as a light emitter, the determination result in S91 is YES, S94 is executed, and the suction tube bending amount is measured. After the measurement, S95 is executed, the suction nozzle 170 is returned to the nozzle stocker 186, and the measurement result and the measurement date and time are written in the tag chip 180.

  The above is production preparation, and production is started after that. If there is a possibility that the operator may change the arrangement of the suction nozzles 170 accommodated in the nozzle stocker 186 after the production preparation and before the start of production, information on all the suction nozzles 170 accommodated in the nozzle stocker 186 is again obtained. Is acquired. The presence / absence of the possibility of changing the nozzle arrangement by the operator is detected based on the presence / absence of an operation that is normally performed along with the change of the nozzle arrangement. For example, if the door provided on the cover covering the electronic circuit component mounting machine is in an open state, the nozzle arrangement may have been changed. The door opening / closing is detected by a door opening / closing sensor 332. The door opening / closing sensor 332 is an aspect of a nozzle arrangement change possibility detection device. An opening / closing detection device for detecting opening / closing of the separation preventing member 286 of the nozzle stocker 186 is provided. After the nozzle stocker 186 is mounted on the stocker mounting portion 280, the separation preventing member 286 is opened in addition to the holding of the suction nozzle 170 by the mounting head 130. If so, the arrangement of the suction nozzles 170 may be changed. If there is a possibility that the nozzle arrangement has been changed to the separation prevention position, the information recorded in the tag chip 180 for all the suction nozzles 170 accommodated in the nozzle stocker 186 is received by the reader / writer 200, and newly Nozzle accommodation information is acquired.

  At this time, if the mounting head 130 holds the suction nozzle 170, the suction nozzle 170 is returned to the nozzle stocker 186 to receive information. Then, the reader / writer 200 is moved to the information receiving / writing positions set for all the nozzle accommodating portions of the nozzle stocker 186 in the same manner as in production preparation, and communicates to obtain nozzle accommodating information. Then, an adsorption tube bending amount / luminance luminance measurement presence / absence display routine is executed. If there is an unmeasured adsorption nozzle 170 and measurement is instructed, the measurement routine is executed.

  As described above, at the start of production, nozzle accommodation information is acquired by acquiring suction nozzle information at the time of production preparation or by acquiring suction nozzle information at the start of production, and the suction nozzle shortage notification routine shown in FIG. 23 is executed. First, in S111, it is determined whether or not the type and number of suction nozzles 170 accommodated in the nozzle stocker 186 are insufficient. It is determined whether or not all of the set types and number of suction nozzles 170 are accommodated in the nozzle stocker 186. The types and number of suction nozzles 170 to be accommodated in the nozzle stocker 186 are set in advance in accordance with the type of the printed wiring board 30 in the component mounting program.

  By acquiring suction nozzle information about the suction nozzles 170 accommodated in the nozzle stocker 186, the type and number of the suction nozzles 170 accommodated in the nozzle stocker 186 can be known. If they are not insufficient, the determination result in S111 is NO S112 is executed, and it is checked whether there is an unusable nozzle that is a suction nozzle 170 that cannot be used for production. This investigation is performed based on the suction nozzle information. In this embodiment, the usable condition of the suction nozzle 170 is that the amount of bending of the suction tube 174 is smaller than the set amount, the luminance of the light emitter is equal to or higher than the set value, the suction error rate (of one suction nozzle 170 The ratio of the total number of suction mistakes generated with respect to the total number of suctions) is smaller than the set value, and the use is not prohibited. The suction nozzle 170 that does not satisfy at least one of these usable conditions is used. Impossible nozzle. In this embodiment, the unusable nozzle is a defective nozzle.

  If there is a defective nozzle, the determination result in S112 is YES, S113 is executed, and it is determined whether there is an alternative nozzle that is a suction nozzle 170 that can be used for production instead of the defective nozzle. As described above, a spare nozzle is accommodated in the nozzle stocker 186, and a suction nozzle 170 of the same type as that of the defective nozzle is accommodated in the nozzle stocker 186. However, it is determined whether or not there is a different type of alternative nozzle that is a suction nozzle that can be used for mounting the component 54 as in the case of the defective nozzle. Depending on the type of the component 54, the type of the suction nozzle 170 that can be used to mount the component 54 is stored in the part data generator in association with the type of the component 54, and can be obtained from the part data generator. A different type alternative nozzle is searched based on the component information, the component mounting program, and the nozzle accommodation information, and the determination in S113 is performed. It is assumed that at least one different kind of alternative nozzle is sufficient. If there is a different type of alternative nozzle, the determination result in S113 is YES and S115 is executed, and the serial number and accommodation position of the alternative nozzle and the serial number and accommodation position of the defective nozzle are stored in association with each other. For example, it is stored in the nozzle accommodation information memory together with the nozzle accommodation information. Although there are defective nozzles, there are also different types of alternative nozzles, which may be displayed and notified that mounting can be performed.

  If there is no alternative nozzle, it is determined that the suction nozzle 170 used for production is insufficient, the determination result in S113 is NO, S114 is executed, and the shortage of the suction nozzle 170 is notified. The reason for the shortage (the presence of a defective nozzle), the serial number of the defective nozzle, the storage position and type in the nozzle stocker 186, etc. are displayed on the display screen 254 and notified. The accommodation position is indicated by the number marked on the nozzle holding hole 284. This number is associated with coordinate values that define the accommodation position, and is holding hole specifying information or identification information that specifies the arrangement of the nozzle holding holes 284 in the nozzle stocker 186. The type of the suction nozzle 170 is specified by, for example, the diameter of the suction tube 174, the diameter of the background forming plate 176, the presence / absence of a light emitter, and the length of the suction tube 170. The operator sees it and accommodates the same kind of suction nozzle 170 as the lacking suction nozzle 170 in the nozzle stocker 186. At this time, the defective nozzle is removed from the nozzle stocker 186, and the suction nozzle 170 instead of the position is accommodated. The suction nozzle 170 is replaced. If there is an empty nozzle holding hole 284 in the nozzle stocker 186, an alternative suction nozzle 170 may be accommodated there. The nozzle holding hole 284 in which the computer is vacant may be designated, and the nozzle housing position for housing the suction nozzle 170 may be designated. Further, the types and the accommodation positions of all the suction nozzles 170 accommodated in the nozzle stocker 186 may be displayed. Thereby, for example, the operator can check whether or not the wrong suction nozzle 170 is stored by comparing with the nozzle storage instruction to the nozzle stocker 186. Alternatively, it is automatically checked whether or not the wrong suction nozzle 170 is accommodated, and if so, the type and the accommodation position of the suction nozzle 170 may be displayed. The same applies to S115, S118, S119, S121, and S122.

  In S114, use prohibition data is set for the defective nozzle, and the use of the defective nozzle is prohibited. The reader / writer 200 moves and writes use prohibition information in the tag chip 180 of the defective nozzle, and the use prohibition is stored for the defective nozzle in the nozzle accommodation information stored in the mounting control computer 230. The serial number of the prohibited nozzle is used. The fact that the use is prohibited is transmitted to the host computer 240. The suction nozzle 170 in which the use prohibition information is recorded on the tag chip 180 is referred to as a use prohibition nozzle. In the present embodiment, the use-prohibited nozzle is a defective nozzle. In the host computer 240, the use prohibition information is stored for the use prohibition nozzles in the suction nozzle information storage unit of the database 262, and the serial number of the use prohibition nozzle is stored in the use prohibition information storage unit provided in the RAM of the host computer 240. . The writing of the use prohibition data to the tag chip 180 and the storage of the use prohibition information in the mounting control computer 230, the host computer 240, etc. are performed in the same manner in S115 and S118 and S119 described later. If there is no defective nozzle, the determination result in S112 is NO, S123 is executed, mounting work start permission data is created, stored in the RAM 224, and the execution of the routine ends. If the mounting work start permission data is created, a series of mounting work may be started, or may be started by an operator instructing the start based on the notification. Similarly, in S115, S119, and S122, mounting work start permission data is created. The execution of S123 may be omitted, and the operator may determine and start the installation work by himself.

  If at least one of the type and the number of the suction nozzles 170 is insufficient, the determination result in S111 is YES and S116 is executed, and it is determined whether there is a defective nozzle as in S112. . If there is a defective nozzle, S117 is executed to determine whether there is an alternative nozzle. In this case, at least one of the type and the number of the suction nozzles 170 is insufficient, and it is determined whether there are different types of alternative nozzles for the suction nozzles 170 and the defective nozzles for which at least one of the types and the numbers is insufficient. There should be at least one alternative nozzle. If there is an alternative nozzle, the determination result in S117 is YES, and S119 is executed in the same manner as S115. In S119, the serial number of the alternative nozzle and the accommodation position are stored in association with the type of the suction nozzle 170 for which at least one of the type and the number is insufficient and the serial number of the defective nozzle. These may be displayed and notified.

  If there is no alternative nozzle, the determination result in S117 is NO, S118 is executed, and a nozzle shortage notification or the like is performed. Here, at least one of the type and number of the suction nozzles 170 is less than the set type and number, that there is a defective nozzle, the serial number and the accommodation position of the defective nozzle are displayed on the display screen 254, and the operator The operator sees the display and replaces the defective nozzle with another suction nozzle 170 or replenishes the insufficient suction nozzle 170. Based on a comparison between the actually acquired suction nozzle information and the set suction nozzle information, a nozzle storage error in the nozzle stocker 186 is detected and notified by display, and a nozzle storage error detection unit is provided. Can also be considered.

  If at least one of the type and number of suction nozzles 170 is insufficient, but there is no defective nozzle, the determination result in S116 is NO and S120 is executed to determine whether there is an alternative nozzle. It is determined whether or not there is a different type of nozzle that replaces the suction nozzle 170 in which at least one of the type and the number is insufficient. If there is an alternative nozzle, the determination result in S120 is YES and S122 is executed. If there is no alternative nozzle, the determination result in S120 is NO, S121 is executed, and nozzle shortage is notified. In S122, although there is an alternative nozzle and production can be performed, it may be notified that at least one of the type and number of suction nozzles 170 accommodated in the nozzle stocker 186 is insufficient. .

  If there is a defective nozzle in the suction nozzle 170 accommodated in the nozzle stocker 186, it is not indispensable to set a different type alternative nozzle, so that the occurrence of the defective nozzle is notified and the defective nozzle is replaced. It may be. In addition, when at least one of the number and type of suction nozzles 170 accommodated in the nozzle stocker 186 is insufficient, it is not essential to set different types of alternative nozzles. Etc. may be performed. When a plurality of sets of suction nozzles 170 necessary for mounting are accommodated in the nozzle stocker, the mounting operation may be started without searching for different types of alternative nozzles when the number is insufficient.

  Prior to the execution of the suction nozzle shortage notification routine, whether or not the wrong (not instructed) suction nozzle 170 is stored in the nozzle stocker 186 is checked based on the nozzle storage information and the storage instruction information. If not, the suction nozzle shortage notification routine is executed. If the suction nozzle shortage notification routine is stored, the suction nozzle shortage notification routine is not executed, and the wrong storage of the suction nozzle 170, the type and position of the suction nozzle 170, etc. are displayed. You may make it alert | report. In that case, after the operator removes or replaces the wrong suction nozzle 170 from the nozzle stocker 186, the nozzle accommodation information is acquired again by acquiring the tag chip information.

  When the shortage of nozzles or the like is displayed on the display screen 254 as described above, the operator replaces the defective nozzle with a non-defective suction nozzle 170 or replenishes the suction nozzle 170, and inputs completion after completion. As a result, the reader / writer 200 is again moved to each information receiving / writing position of all the nozzle accommodating portions, and receives the suction nozzle information. As a result, the nozzle accommodation information is acquired, and there is an adsorption nozzle 170 whose bend of the adsorption tube 174 has not been measured, and if measurement is instructed, the measurement is performed, and the adsorption nozzle 170 is insufficient or has a defective nozzle. If there is no alternative nozzle, it is notified and replacement and replenishment are performed. These are repeatedly executed until the amount of bending of the suction pipe 174 and the like are acquired, and the types and number of suction nozzles 170 sufficient for production are accommodated in the nozzle stocker 186.

  As described above, when the suction nozzles 170 are aligned in the nozzle stocker 186 and information is acquired for all the suction nozzles 170 accommodated therein, the mounting of the component 54 onto the printed wiring board 30 is started. The mounting of the component 54 on the printed wiring board 30 has been described above, and acquisition and use of suction nozzle information will be described in detail here.

  When the component 54 is mounted on the printed wiring board 30, the mounting head 130 moves to the nozzle stocker 186, holds the necessary suction nozzle 170 based on the mounting order and the nozzle accommodation information, and the component 54 from the feeder 50 or the component tray 110. Is attached to the printed wiring board 30. When a plurality of suction nozzles 170 of the same type are accommodated in the nozzle stocker 186, the order of use is determined and used in accordance with a preset rule. For example, the suction nozzle 170 that is used (sucked) less frequently is used first. The suction nozzle 170 with the smallest number of suction mistakes may be used first, the suction nozzle 170 with the fewest number of image processing errors may be used first, or the suction nozzle 170 to be used may be determined in combination. Good. The use order is determined using the suction nozzle information, and the nozzle use order determination unit is also an aspect of the information use unit. When the type of the suction nozzle 170 accommodated in the nozzle stocker 186 is insufficient and an alternative nozzle is set, a different type of alternative nozzle set in advance is determined as the use nozzle instead of the insufficient suction nozzle 170, and the replacement is performed. A nozzle holding routine shown in FIG. 24 is executed for the nozzles. Further, when the use-prohibited nozzle is accommodated in the nozzle stocker 186, the suction nozzle 170 is not used, and an alternative nozzle is used by executing the nozzle holding routine.

  When the mounting head 130 holds the suction nozzle 170, a nozzle holding routine shown in FIG. 24 is executed. In S201 of this routine, it is determined whether or not the suction nozzle 170 to be held is prohibited. This determination is made based on the suction nozzle information constituting the nozzle accommodation information. If the use is not prohibited, the determination result in S201 is NO, the steps in S202 and subsequent steps are executed, and the type of the suction nozzle 170 is confirmed. Is done. The nozzle type confirmation described above based on the nozzle type confirmation routine shown in FIG. 12 is specifically performed here. The mounting head 130 is moved to the nozzle accommodation position, and the reader / writer 200 performs information processing. It is moved to the receiving / writing position and lowered to the lower end position to communicate with the tag chip 180, and the type of the suction nozzle 170 is confirmed based on the suction nozzle information obtained thereby. If the type of the suction nozzle 170 is to be held, S205 is executed, and the mounting head 130 holds the nozzle. If the mounting head 130 holds the suction nozzle 170, the suction head 170 is returned to the nozzle stocker 186 prior to holding the nozzle.

  If the suction nozzle 170 is not of the kind to be held, S203 is NO and S204 is executed, and this is displayed and notified. After obtaining the nozzle accommodation information at the start of production, there is a possibility that the arrangement of the suction nozzle 170 has been changed, and this is notified, and the electronic circuit component mounting machine is stopped.

  If the suction nozzle 170 to be held is a use-prohibited nozzle, the determination result in S201 is YES and S206 is executed to determine whether there is an alternative nozzle. This determination is based on whether or not the nozzle stocker 186 contains a usable suction nozzle of the same type as the use-prohibited nozzle, or whether or not a different kind of suction nozzle can be used and can be replaced. It is done depending on whether or not. The same type of alternative nozzle is preferentially used, and when there is no same type of alternative nozzle, a different type of alternative nozzle is used. Therefore, in S206, based on the nozzle accommodation information, first, the same type alternative nozzle is searched, and if not, the different type alternative nozzle is searched and the determination is performed. In the case where the use is prohibited in the state where the suction nozzle that is a different type alternative nozzle is used as an alternative nozzle, when the determination of S206 is made, the nozzle itself is already an alternative nozzle and there is no alternative nozzle.

  For the suction nozzles 170 that are not permitted to be used when stored in the nozzle stocker 186 and the types of suction nozzles 170 whose number is insufficient, different types of alternative nozzles are set in the suction nozzle shortage notification routine. Although the determination of S206 is executed, as will be described later, a different type of alternative nozzle is not set for the suction nozzle 170 that is prohibited from use during production, and is the same as in S113 of the suction nozzle shortage notification routine. In addition, an alternative nozzle is searched from the suctions accommodated in the same nozzle stocker 186. Information about the alternative nozzle, for example, its type and storage position is stored in association with the serial number of the use-prohibited nozzle. If there are no alternative nozzles of the same type or different types, the determination result in S206 is NO, S207 is executed, and that is displayed, notified, and the electronic circuit component mounting machine is stopped. As will be described later, when a defective nozzle is detected in the nozzle use prohibition routine, an alternative nozzle is searched. Therefore, the alternative nozzle may be stored, and S206 may be executed based on the information.

  If there is an alternative nozzle, the determination result in S206 is YES, the steps in S208 and subsequent steps are executed, and the suction nozzle 170 is held after confirming the type. In this way, the mounting head 130 holds the suction nozzle 170 in accordance with the mounting order (mounting program) and nozzle accommodation information, and the mounting control computer 230 knows which suction nozzle 170 is actually used for mounting. Yes.

  When determining the suction nozzle to be used for mounting, first, it may be determined whether or not the suction nozzle is prohibited from being used, and the use nozzle may be determined from the usable suction nozzles. In this case, if there are a plurality of usable nozzles, the nozzles to be used are determined according to a preset rule. At that time, if there is no suction nozzle of the kind that is instructed to be used and there is no suction nozzle that can be used, search for a different type of alternative nozzle, if it is used, notify it, and if not, notify the electronic circuit component mounting machine Stop. If a different type alternative nozzle is set in advance, it is used. Then, a nozzle type confirmation routine shown in FIG. 12 is executed when holding the suction nozzle that has been determined to be used.

  When the component 54 is mounted on the printed wiring board 30, the number of times of suction, the number of suction mistakes, and the number of image processing errors are counted for each suction nozzle 170. As shown in FIG. 30, the suction nozzle information is stored in the RAM 224 in association with the nozzle housing position. Of these, the portion that stores the number of times of suction, the number of suction mistakes, and the number of image processing errors is constituted by a counter. Each count is counted and updated. The number of suctions, the number of misses, and the number of errors stored in the tag chip 180 are the total number (cumulative) of suction, misses, and errors that have been performed in the past for the suction nozzle 170 provided with the tag chip 180. The initial value of the counter is the number of times of adsorption recorded in the tag chip 180, and is set to the latest value. In addition to storing the suction nozzle information, a counter is provided to count the number of suctions, the number of mistakes, and the number of errors when the suction nozzle 170 is held by the mounting head 130 and used for mounting. When returning to the stocker 186, the count may be added to the number of times stored in the nozzle accommodation information memory and stored, and the number of times recorded in the tag chip 180 may also be recorded. These counters are reset to 0 each time the suction nozzle 170 is returned to the nozzle stocker 186 or each time the suction nozzle 170 is taken out from the nozzle stocker 186.

  In the present embodiment, the suction error is that the part 54 could not be picked up even though the suction nozzle 170 performed the suction operation, and that the part 54 could be picked up but was picked up in a standing posture. A suction error is detected based on image data obtained by imaging the component 54. If the difference between the dimension of the component 54 obtained by imaging and the normal dimension without error or deviation is equal to or greater than the set value, it is assumed that the type is wrong or that it is sucked in a standing posture.

  In this embodiment, the image processing error is the actual lead interval if the component 54 is applied, if the rotational position error and the translational position error cannot be acquired within the set time, or if the component 54 has leads. An image processing error occurs when the difference from the regular interval is greater than or equal to the set value, or when the lead is bent.

  When replacing the suction nozzle 170 used for mounting, the suction nozzle 170 currently held by the mounting head 130 is returned to the nozzle stocker 186, and the suction nozzle 170 to be used next is held. Is returned to the nozzle stocker 186, and updated information such as the number of times of suction is written into the tag chip 180. The latest information is recorded in the tag chip 180.

  The mounting control computer 230 also stores production information. For example, as shown in FIG. 31, the production information includes the wiring board ID, the component mounting position, the type of the component 54 mounted at the component mounting position, and the mounting position of the feeder 50 that supplied the component 54 on the feeder support base 48. , Feeder ID, information on the suction nozzle 170 on which the component 54 is mounted, component mounting time, and the like. The information related to the suction nozzle 170 includes a serial number, the number of suctions, the number of suction mistakes, suction mistake data, the number of image processing errors, and error data. Each of these times is the total number (accumulation) at that time, and is obtained from the suction nozzle information stored in the nozzle accommodation information memory. The suction error data and the error data are each stored as a code. The code and the data representing the content of the error or error represented by the code are stored in the host computer 240 and the mounting control computer 230 in association with each other, and the content of the error or error is known from the code. This production information is also a production information history.

  The suction nozzle 170 is replaced in accordance with the type of the component 54 to be mounted. For example, the suction nozzle 170 is also replaced when it is estimated that the suction nozzle 170 is frequently used and cannot be used. This nozzle replacement is performed according to a nozzle use prohibition routine shown in FIG. This routine is executed during production in the mounting control computer 230, for example, every time one component 54 is mounted.

  In S161, it is determined whether or not the suction nozzle 170 held by the mounting head 130 and used for mounting the component 54 is an unusable defective nozzle. If the suction error rate (the ratio of the total number of mistakes with respect to the total number of suctions) after the start of a series of mounting operations on the same type of printed wiring board 30 is equal to or higher than the set rate, This is a possible defective nozzle, and the determination result in S161 is YES, and S162 is executed to determine whether or not replacement is possible. In this embodiment, spare nozzles are accommodated in the nozzle stocker 186 and a plurality of the same kind of adsorption nozzles 170 are accommodated, and the same kind of adsorption nozzles 170 that are not prohibited from being used are arranged. If present, it is first used for mounting. If there is no similar kind of suction nozzle 170 that can be used, an alternative nozzle is searched for different kinds of suction nozzles 170. For a suction nozzle of the same type as the suction nozzle forbidden to be used, a different type alternative nozzle is set when being accommodated in the nozzle stocker 186, and the different type alternative nozzle is used if possible. If any of the suction nozzles 170 can be replaced with a defective nozzle, the determination result in S162 is YES, S163 is executed, and the suction nozzle 170 is replaced. The defective nozzles currently held by the mounting head 130 are returned to the nozzle stocker 186, and the suction nozzles used in place of the defective nozzles are held. Also during this return, it is confirmed that the nozzle holding hole 284 is empty, and during the holding, the type of suction nozzle is confirmed. Then, S164 is executed, and the use of the suction nozzle 170 is prohibited. This prohibition of use is performed in the same manner as S114 in the suction nozzle shortage notification routine shown in FIG. Here, since the mounting operation is in progress, use prohibition data is written to the defective nozzle tag chip 180 returned to the nozzle stocker 186, and updated data is written during use. Also stored in the mounting control computer 230 or the like.

  Thus, by prohibiting the use of defective nozzles before or during production, for example, the use of nozzles that are prohibited from use cannot be eliminated without causing the cause of prohibition of use. For this reason, even if it is accommodated in the nozzle stocker 186, when the suction nozzle shortage notification routine is executed, it is determined that there is a use-prohibited nozzle and it is avoided that it is used for mounting. Further, the nozzle use prohibition information is accumulated in the host computer 240 and displayed on the display screen 265 as shown in FIG. 32 so that the operator does not store the use prohibition nozzles in the nozzle stocker 186.

  If there is no suction nozzle 170 that can be replaced even if a defective nozzle is generated, the determination result in S162 is NO, S165 is executed, and that fact is displayed and notified. Furthermore, the electronic circuit component mounting machine is stopped.

  Even if suction mistakes occur frequently as described above and the suction nozzle is a use-prohibited nozzle, or even if it is a use-prohibited nozzle because the luminance of the illuminant is lower than the set value, it can be used if the cause of use prohibition is resolved. The ban is lifted. For example, if the cause of prohibition of use of the suction nozzle 170 is resolved by performing maintenance such as cleaning of the light emitter and cleaning of the suction pipe 174, the operator inputs the fact to the host computer 240 to cancel the prohibition of use. Like that. After the maintenance, it is desirable that the inspection device inspects whether the suction nozzle 170 can normally mount the component 54.

  If execution of the use prohibition release is input, the use prohibition release routine shown in FIG. 26 is executed, and it is determined whether or not the serial number of the suction nozzle 170 has been input in S181. If the serial number of the suction nozzle 170 for canceling the prohibition of use is input, the determination result in S181 is YES, S182 is executed, and the prohibition of use is cancelled. The use prohibition information stored in the use prohibition information storage unit of the host computer 240 and the information regarding the suction nozzle 170 having the inputted serial number is deleted. In addition, the serial number or the like is also sent to the mounting control computer 230 so that the use prohibition is released. For the suction nozzle, for example, the use prohibition information recorded on the tag chip 180 is erased using the portable reader / writer 248. In addition, the number of suction mistakes at the time of use prohibition release input, use prohibition release date and time, and the like may be stored as a kind of suction nozzle information.

  At the time of component mounting, if necessary for the suction nozzle 170 held by the mounting head 130, the operation data is corrected based on correction data acquired in advance. For example, when the suction pipe 174 is shortened due to wear or the like of the suction end face, the up / down stroke of the mounting head 130 during the suction and mounting of the component 54 is corrected. For example, as described in Japanese Patent Laid-Open No. 2001-345599, an imaging device captures an image of the adsorption tube from a direction orthogonal to its axis, acquires the position of the adsorption end surface, and acquires the actual length of the adsorption tube 174. And the correction amount is calculated by comparing with the normal length recorded in the suction nozzle information. The imaging device and the image processing computer constitute a position error acquisition device or correction data acquisition device. The correction amount is measured, for example, when the suction nozzle 170 is not used for mounting and is not accommodated in the nozzle stocker 186, and is stored in the host computer 240 in association with the serial number of the suction nozzle 170 and the acquisition date and time. Yes. The change information may be recorded on the tag chip 180 of the suction nozzle 170.

  When the suction nozzle 170 takes out the component 54 from the feeder 50 and when it is mounted on the printed wiring board 30, the up / down stroke correction routine shown in FIG. 27 is executed. In S191 of this routine, the correction amount is read from the host computer 240 based on the serial number of the suction nozzle 170, and the ascending / descending stroke is corrected based on the correction amount in S192. Note that a correction data acquisition device may be provided in the electronic circuit component mounting machine to acquire the correction amount. If the correction amount is not stored in the host computer 240, or if it is stored, it is old, and if the set period has elapsed since its acquisition or the number of times of mounting exceeds the set number, the correction amount Is preferably not used, and the electronic circuit component mounting machine obtains a correction amount to correct the lifting stroke. The acquired correction amount is sent to the host computer 240 and stored together with the serial number of the suction nozzle 170 and the acquisition date and time.

  Production information and suction nozzle information are transmitted to the host computer 240 every time the mounting of the component 54 on one printed wiring board 30 is completed, and the production information is stored in the database 262. It may be stored in a production information storage unit provided in the RAM of the host computer 240. Further, the suction nozzle information in the database 262 is updated based on the suction nozzle information. For example, if the change information such as the number of times of suction among the information regarding the suction nozzle 170 is updated, the number of times of suction of the suction nozzle 170 in the database 262 is updated. As a result, the same information as the information recorded on the tag chip 180 of the suction nozzle 170 housed in the nozzle stocker 186 is stored in the database 262.

In the host computer 240, during the production, maintenance guidance and notification of the possibility of defective nozzles are performed based on the suction nozzle information.
The maintenance guidance is performed according to the maintenance guidance routine shown in FIG. This routine is executed for all the suction nozzles 170 that are actually housed in the nozzle stocker 186 and used for production, and the mounting of the component 54 on one printed wiring board 30 is completed, and new suction nozzle information is obtained. It is executed every time it is executed. In S131, it is determined whether or not the number of times of suction is equal to or greater than the set number. In the present embodiment, the number of times of suction is the number of times from the latest maintenance execution to the execution of S131. For this reason, the host computer 240 is provided with a suction number storage unit for maintenance guidance determination, and for each of the suction nozzles 170, the suction number of the suction nozzle 170 at the time when the latest maintenance is executed is the serial number of the suction nozzle 170. They are stored in association with each other. The determination in S131 is made based on whether or not the difference between the number of suctions of the suction nozzle 170 obtained from the suction nozzle information and the number of suctions at the time of the latest maintenance execution is greater than or equal to the set number, and the number of suctions is less than the set number. If so, the determination result in S131 is NO and the execution of the routine ends.

  If the number of suctions is equal to or greater than the set number, the determination result in S131 is YES, S132 is executed, and maintenance guidance is output to the mounting control computer 230. In this embodiment, the maintenance guide condition is that the number of times of suction after the latest maintenance is performed is equal to or greater than the set number of times. Number and maintenance execution instruction are output. When the maintenance control is supplied, the mounting control computer 230 displays it on the display screen 254 and notifies the operator. The operator performs maintenance such as cleaning of the suction tube 174 and the background forming plate 176 after the completion of production or after the completion of component mounting on one printed wiring board 30 according to the maintenance guide.

  When the operator finishes the maintenance, the operator inputs the serial number of the suction nozzle 170 that performed the maintenance and the fact that the maintenance is completed to the mounting control computer 230, and the mounting control computer 230 sends the information, the maintenance execution date and time, etc. to the host computer 240. . An operator may input directly to the host computer 240. In the host computer 240, based on the maintenance execution information including the serial number of the suction nozzle 170 for which maintenance has been performed, the suction nozzle 170 for which maintenance has been performed among the maintenance guide determination suction frequency storage units of the maintenance execution information storage unit. Is stored, and the number of suctions obtained from the suction nozzle information stored in the database 262 at the time when maintenance execution information is acquired is stored as the number of suctions at the time of maintenance execution. As described above, since the host computer 240 stores maintenance execution information for the suction nozzle 170, even if the electronic circuit component mounting machine in which the suction nozzle 170 is used changes, maintenance information is used using the information. Can be put out.

  The failure possibility nozzle notification is performed according to the failure possibility nozzle notification routine shown in FIG. The failure possibility nozzle is the suction nozzle 170 that is likely to become a failure nozzle, and the failure possibility nozzle notification routine is performed every time mounting of the component 54 on one printed wiring board 30 is completed. The failure possibility nozzle notification routine may be performed while the mounting operation is being performed in the mounting control computer 230. In S141 of this routine, it is determined whether or not the suction error rate is equal to or higher than the set rate for the suction nozzle 170 that is actually used for mounting the component 54. This suction error rate is a rate of all suction mistakes generated in the suction nozzle 170 with respect to the total number of suctions. It is set to be larger than the set rate of S141.

  If the suction error rate is equal to or higher than the set rate, the determination result in S141 is YES, S142 is executed, and the occurrence of a defective possibility nozzle is notified. The serial number of the suction nozzle 170 whose suction error rate is equal to or higher than the set rate and information indicating that there is a possibility of a defective nozzle are sent to the mounting control computer 230, which is displayed on the display screen 254. Display and notify the operator. Based on the display, the operator recognizes that there is a suction nozzle 170 that may be prohibited in the near future. For example, the suction nozzle 170 is prepared for replacement or the notified suction nozzle If the suction nozzle 170 is frequently notified as a defective possibility nozzle even if maintenance is performed, the suction nozzle 170 is appropriately dealt with, for example, by performing careful maintenance or inspection after the production is finished. be able to. The host computer 240 also stores the serial number of the defective nozzle and the possibility nozzle.

  The information on the possibility of failure nozzles is also supplied to other mounting machines and notified to the operator. The display screen 254 displays the serial number for the defective nozzle and information indicating the possibility of the defective nozzle. Based on this display, the operator can appropriately deal with the possibility of defective nozzles in other mounting machines. Since the possibility nozzle is not so bad that use is prohibited, it is used for mounting. However, in other mounting machines, it is informed from the beginning of mounting that the nozzle is likely to be defective, and the operator is quick. Can be dealt with from the time.

  If the suction error rate is smaller than the set rate, the determination result in S141 is NO and the execution of the routine ends. The release of the possibility nozzle is omitted, for example, in the same manner as the use prohibition release of the suction nozzle 170 although illustration and description of the flowchart are omitted. When the operator performs maintenance or the like based on the notification of the possibility nozzle, and the cause of the defect is eliminated, the fact and the serial number of the possibility nozzle are input to the host computer 240, thereby the suction nozzle 170. The defect possibility information regarding is deleted. Once the adsorption error rate becomes equal to or higher than the set rate, an adsorption error does not occur thereafter, and the adsorption error rate may be smaller than the set rate. For this reason, if the determination result in S141 is NO, the failure possibility information may be deleted.

  The failure possibility nozzle detection condition includes, for example, whether or not the suction error rate is equal to or higher than the set rate, for example, that the image processing error rate is equal to or higher than the set rate, the suction error frequency is equal to or higher than the set number, and image processing The number of errors may be greater than or equal to the set number. These may be combined. The same applies to the use-prohibited nozzle detection conditions.

  In the host computer 240, production history information is created based on the production information and suction nozzle information stored in the database. The production history information can be created at any time such as during production or after production. For example, the operator sets a period for collecting information for creating production history information using the input device 260, and indicates a list display of all the suction nozzles 170 used for mounting within the set period. For example, as shown in FIG. 33, suction nozzle information is displayed on the display screen 254 of the host computer 240 using the serial number assigned to the suction nozzle 170 as a key. The setting period can be set in various ways, for example, from 8:00 am to 5:00 pm on the last day of the month. The production history information creation conditions are set by the operator.

  There are various types of information regarding the suction nozzle 170, but normally, as shown in FIG. 33, production history information is created including basic items which are preset items. The number of adsorptions may be the number of adsorptions within the set period (the number of adsorptions performed from the start to the end of the set period), and is the total number of adsorptions at the end of the set period, the total number of adsorptions before the set period And the number of adsorptions within the set period. Further, each of the suction error and the image processing error is displayed as an occurrence rate (a ratio of the number of suction mistakes to the number of suctions and a ratio of the number of image processing errors to the number of suctions). These occurrence rates may also be the ratio of the number of suction mistakes and the number of image processing errors that occurred within the set period to the number of suctions within the set period, and are calculated including the total number of suctions, the number of mistakes, and the number of errors before the set period. It may be the occurrence rate. Whether the number of suctions and the occurrence rate of suction mistakes, etc. are determined within the set period or including the period before the set period is set by, for example, an operator. You may ask for both. In addition to these basic items, other items according to the operator's settings, for example, specified items specified by the operator, such as the wiring board ID of the printed wiring board 30 on which the component 54 is mounted by the suction nozzle 170, the type of the component 54, etc. Production history information can be created and displayed.

  Then, for any of the displayed suction nozzles 170, any one of the number of suction times, the suction error rate, the image processing error rate, etc. is selected and the data is displayed in ascending or descending order. The suction nozzle 170 having a large image processing error rate can be easily obtained, and the suction nozzle 170 likely to cause a problem can be quickly identified.

  Further, in order to create production history information, the operator inputs the wiring board ID of the printed wiring board 30 and includes all the suction nozzles 170 used for mounting the component 54 on the printed wiring board 30. If specified as the production history information creation condition, production history information including information about the suction nozzles 170 is displayed on the display screen 254 as shown in FIG. If the same suction nozzle 170 is used a plurality of times for mounting the component 54 on the printed wiring board 30, the number of times of suction, the suction error rate, and the image processing error rate are the values at the last use. Is displayed.

  In this way, since all the suction nozzles 170 are assigned serial numbers, the suction nozzles 170 can be individually identified even if the suction nozzles 170 are used for mounting the component 54 on any type of printed wiring board 30. At the same time, the usage status can be aggregated to obtain the current status. In addition, the amount of information that can be recorded on the tag chip 180 is large, and a large amount of information can be recorded both in terms of type and quantity, and the information can be updated. It can be used in various modes such as confirmation of type and determination of availability. Furthermore, since the production information is created by associating the wiring board ID with the serial number of the suction nozzle 170, production history information including information about the suction nozzle 170 can be created based on the wiring board ID. For example, when the component 54 is not properly mounted on the printed wiring board 30 and a defective printed circuit board is manufactured, the cause can be analyzed including the suction nozzle 170. Further, based on the serial number of the suction nozzle 170, production history information including information on all the printed wiring boards 30 used for mounting the suction nozzle 170 is created, and the type of the component 54 in which the suction error has occurred is included. Production history information can be created.

  Further, the inspection result by the mounting inspection machine 266 is supplied to the host computer 240. If the mounting is not normally performed, a mounting sequence number for mounting the component 54 in which mounting abnormality has occurred is displayed on the display screen 264 and notified, and if the operator specifies the mounting sequence number, The suction nozzle 170 used for mounting is obtained from the component mounting position corresponding to the mounting sequence number, and information about the suction nozzle 170 is displayed on the display screen 264. The operator can identify the suction nozzle 170 that may cause the mounting accuracy failure by viewing the display.

  The mounting mode in which the plurality of suction nozzles 170 are used for mounting the component 54 on one type of printed wiring board 30 and the suction nozzles 170 are replaced during production has been described above, but one type of printed wiring board 30 is described. There is also a printed wiring board 30 in which only one suction nozzle 170 is used for mounting the component 54 on the substrate, and the suction nozzle 170 is not replaced during production. In that case, when the suction nozzle 170 is returned to the nozzle stocker 186 when the production is completed and the setup change is performed, the information acquired during the production is written in the tag chip 180. For example, when the suction nozzle 170 is replaced with a spare suction nozzle 170 accommodated in the nozzle stocker 186 due to an abnormality in the suction nozzle 170, the information is returned after the abnormal suction nozzle 170 is returned to the nozzle stocker 186.

The holding device 414 is moved to an arbitrary position in the horizontal plane.

  The plurality of mounting heads 434 are swung around a vertical axis that is a common swivel axis by the head swivel device 436 and are sequentially stopped at a plurality of stop positions. The head turning device 436 includes an intermittent rotating body 438 as a rotating body provided to be rotatable around a vertical axis, and a rotating body rotating device (not shown) that intermittently rotates the intermittent rotating body 438. The intermittent rotation causes the intermittent rotating body 438 to sequentially move the plurality of mounting heads 434 held at equal angular intervals around the rotation axis to the component receiving position, the component imaging position, the component mounting position, and the like.

  The component supply device 418 includes a plurality of, for example, two component supply tables 450 and a component supply table moving device 452. The two component supply tables 450 are similarly configured and include a plurality of feeders 454 as component holders and a feeder support base 456 on which the feeders 454 are mounted along the X-axis direction. The component supply table moving device 452 moves each of the two component supply tables 450 in the X-axis direction, sequentially positions each component supply unit of the plurality of feeders 454 at the component supply position, and the feeder 454 moves from the component supply unit. Supply parts one by one.

  The wiring board imaging system 420 is provided by fixing the position of a support member (not shown) provided on the bed 410, and any part of the printed wiring board 428 is moved to the imaging position by the movement of the wiring board holding device 414. , Imaged. The component imaging system 422 is provided at a component imaging position that is one of the stop positions of the mounting head 434, and images a component that is sucked by a suction nozzle held by the mounting head 434. In addition, a reader / writer 462 that receives information from a tag chip 460 provided on the printed wiring board 428 is provided. This reader / writer 462 is provided in a moving region of the printed wiring board 428 and is supported by a support member and fixed in position. Although not shown, a reader / writer (not shown) that receives information from a tag chip (not shown) provided on a taping component (not shown) held by the feeder 454 in the vicinity of the component receiving position of the mounting head 434. ) Is supported by a support member and fixed in position. Further, a reader / writer that automatically receives information from the tag chip provided in the suction nozzle may be provided. The electronic circuit component mounting machine 402 is controlled by a control device 470 configured similarly to the control device 24. The control device 470 is connected to a host computer 472 (see FIG. 35) that manages and controls the entire electronic circuit assembly system. In FIG. 35, reference numeral 474 denotes a database, which is configured in the same manner as the database 262.

  Also in the electronic circuit component mounting machine 402, information recorded on the tag chip provided in the taping component or the feeder is used for checking the type of the component when the feeder 454 is mounted on the feeder support base 456 and managing the remaining number of components in the feeder 454. Used. Also, information recorded on the tag chip 460 of the printed wiring board 428 carried into the electronic circuit component mounting machine 402 is received by the reader / writer 462, the wiring board ID, etc. are acquired, and used for production information production. Furthermore, when the mounting head 434 holds the suction nozzle, the type of the suction nozzle is confirmed by receiving information recorded on the tag chip provided on the suction nozzle, and the suction nozzle information such as the serial number is also displayed. Are stored in the computer in association with the attachment position (obtained by the data specifying the mounting head 434 and the nozzle holding position in the mounting head 434). The information recorded on the suction nozzle tag chip is received by an operator when the suction nozzle is attached to the mounting head 434, for example, using a portable reader / writer. If possible, the suction nozzle information may be automatically received by a reader / writer moved by the moving device.

  Each of the plurality of electronic circuit component mounting machines 400 and 402 is also provided with a mounting machine ID as a work machine ID for individually identifying them. The mounting machine ID is recorded in an information recording unit such as a two-dimensional code or an electronic tag provided in the electronic circuit component mounting machines 400 and 402, and is acquired by a mounting machine ID acquisition apparatus as a work machine ID acquisition apparatus. The mounting machine ID is acquired when the arrangement and work order of various work machines such as an electronic circuit parts mounting machine are set in the electronic circuit parts assembly system and the work machines are actually arranged. The mounting machine ID is work machine individual identification information that is a type of work machine information, and may further record other information such as the type of the mounting machine, the date of manufacture, and the like.

  Also in this electronic circuit assembly system, information recorded on a tag chip or the like provided on a suction nozzle or the like is variously used. For example, when the use-prohibited nozzle is displayed on the display screen and notified, and the suction nozzle is held by the plurality of mounting heads 434 of the electronic circuit component mounting machine, the operator determines whether or not the use of the suction nozzle is prohibited. It is possible to check and prevent use prohibition nozzles from being used for mounting. Further, by acquiring suction nozzle information, a suction nozzle used for mounting in the electronic circuit component mounting machine can be obtained. During production, the number of suctions, the number of suction mistakes, and the number of image processing errors are counted for each of the plurality of suction nozzles, change information is acquired, and the serial numbers of the suction nozzles used for component mounting are wired. Production information is created by being stored in association with the board ID, component mounting position, mounted component, etc., and sent to the host computer 472 to be stored in the database 474. In the host computer 472, the electronic circuit component mounting machines 400 and 402 are identified by the mounting machine ID, and the production information is stored by identifying the electronic circuit component mounting machines 400 and 402. Furthermore, the host computer 472 performs maintenance guidance, detection of a defective nozzle, and the like, and if there is a defective nozzle or a prohibited nozzle, it is stored. In addition, production history information is created at an arbitrary time. Information about the suction nozzle acquired or updated during production is stored in the computer of the control device 470 or the host computer 472. For example, when the suction nozzle is removed from the mounting head 434, it is suctioned by a portable reader / writer or the like. Information is written to the tag chip of the nozzle and written to the tag chip using a recording device.

  The electronic circuit assembly system includes a plurality of electronic circuit component mounting machines 400 and 402, and the suction nozzle may be used in the electronic circuit component mounting machine 400 or used in the electronic circuit component mounting machine 402. However, a serial number is assigned to each suction nozzle, and the suction nozzle is individually identified regardless of which electronic circuit component mounting machine is used. For this reason, the usage status of each electronic circuit component mounting machine and the usage status of the same electronic circuit component mounting machine at different times can be acquired for each suction nozzle and can be associated with each other for use in the production of printed circuit boards. Production information capable of managing and grasping the state of the suction nozzle thus obtained is obtained, and production history information including information about the suction nozzle used for mounting can be created in various modes. For example, it can be created for each printed wiring board 472, for each type of printed wiring board 472, for each mounting machine, or by setting an information collection period. Further, the use status (change information) such as the number of times of suction is obtained for each suction nozzle, and the current status of the suction nozzle can be acquired.

  In the above embodiment, the feeder-type component supply device 18 is connected to the taping component 58, the feeder 50 is replaced, and the next designation is performed. Alternatively, only two may be performed. Also in the tray type component supply apparatus 20, only one of the replacement of the component tray 100 and the next designation may be performed.

  Further, the type of the component 54 accommodated in the component supply devices 18 and 20 is confirmed when being mounted on the feeder 50, the feeder support 48 of the component tray 110, and the component tray accommodating box 114. The confirmation work by the worker at the time may be omitted. In this case, for example, in the case of the feeder-type component supply device 18, the tag chips provided on the feeders 50 are mounted after all the feeders 50 necessary for mounting the components 54 on the printed wiring board 30 are mounted on the feeder support base 48. 98 is read by the reader / writer 200. At this time, the reader / writer 200 is moved onto the tag chip 98 to be read and moved to the lower end position, and wireless communication may be performed between the tag chip 98 and the tag chip 98 of the adjacent feeder 50. It can be lowered to a distance with no. The feeder information is obtained by receiving the information recorded in the tag chip 98, whereby the type of the component 54 can be confirmed, and the feeder 50 that holds the component 54 of a type different from the set type is mounted. Notification and exchange processing is performed. The information recorded on the tag chip 98 may be received when the electronic circuit components are taken out for the first time after each of the plurality of feeders 50 is mounted.

  When the electronic circuit components are replenished by connecting the taping electronic circuit components, the tag chip information provided on the new taping electronic circuit components is not read at the time of connection work, and the reader is required to detect the tag chip at the time of supplying the electronic circuit components. / When communication is performed with the writer, the type of the taping electronic circuit component connected may be confirmed based on the information read by the communication. At this time, if the wrong type of taping electronic circuit component is connected, for example, the electronic circuit component mounting machine is stopped.

  Further, when a tag chip is provided on the taping electronic circuit component, it may be provided on a carrier tape. For example, a tag chip is attached to a portion between the feed holes. The cover is provided with an opening through which the teeth of the sprocket constituting the tape feeder protrude, and information is read in a state where the tag chip is located in the opening. Alternatively, a tag chip may be provided on the cover tape. In this case, for example, information is read in a state where the tag chip provided on the cover tape is located upstream from the cover.

  The tag chip may be provided in a unit or device that constitutes the electronic circuit assembly system. For example, a multi-feeder unit configured so that a plurality of feeders can be attached to and detached from the main body of the mounting machine in a batch, and a plurality of component trays can be mounted in a batch for each support member. A tag chip may be provided in a multi-tray unit that is configured to be attached to and detached from the main body of the machine so that information is recorded, and may be used, for example, for replenishment of parts.

  Further, information may be written to the tag chip. For example, before removing the feeder from the feeder support in the feeder-type component supply device at the time of changing the setup, the remaining number of electronic circuit components held by the feeder is written and recorded on the tag chip of each feeder. Accordingly, when the feeder is used as it is for the supply of electronic circuit components, the information stored in the tag chip is received by the receiving device, thereby holding the electronic circuit components held by the feeder at the start of a series of mounting operations. It is a number and the initial accommodation number is obtained.

  Further, the information recorded in the tag chip may be received with the reader / writer stopped.

  Also, if one feeder supplies electronic circuit components to a single circuit board at a plurality of different times, the feeder replacement startable period is calculated in consideration thereof.

  Furthermore, the acquisition of the component shortage feeder and the acquisition of the component replenishment time may be performed during the component mounting operation.

  Moreover, you may utilize the tag chip | tip provided in the component holder for the accommodation to the holder accommodation apparatus of a component holder other than replacement | exchange of a component holder, for example. When the storage position of the component holder to the holder storage position is set in advance, whether or not the predetermined component holder is stored at the predetermined storage position is recorded on the tag chip provided on the component holder. It is confirmed using the information. In this case, a component holder accommodation support unit that is a kind of component support related work support unit is provided.

  Furthermore, although the tag chip is provided in each component of the electronic circuit assembly system such as the suction nozzle 170, a two-dimensional code may be provided instead of the tag chip to configure the information recording unit. The two-dimensional code is a read-only information recording unit. For example, identification information and invariant information are recorded and read by an information reading device. The information reading device is configured by an imaging device as a recognition device, for example. The imaging device is constituted by, for example, a CCD camera as an imaging device. When a two-dimensional code is provided for the suction nozzle, if the presence or absence of the suction nozzle in the nozzle stocker is detected based on the difference in light reflectance between the nozzle holding hole and the background forming member of the suction nozzle, the two-dimensional code The information can be read by the imaging device, and the reflectance of light is different from the nozzle holding hole, and it is formed in the color that the suction nozzle is supposed to be even when the two-dimensional code is irradiated with light. It is desirable. When providing a two-dimensional code, if the amount of information recorded is insufficient, for example, it is stored in a computer in association with individual identification information or type related information of a member provided with the two-dimensional code, and stored in the two-dimensional code. Based on the reading of the individual identification information or the like, the information associated with them may be read and used. The same applies to the information recording unit where the recording amount is insufficient other than the two-dimensional code.

  The nozzle stocker 186 accommodates a suction nozzle 170 used for mounting the component 54 on one type of printed wiring board 30. When the type of the printed wiring board 30 changes and the setup is changed, the nozzle stocker 186 is used. However, the nozzle stocker may accommodate suction nozzles used for mounting components on a plurality of types of printed wiring boards. A common suction nozzle may be shared by a plurality of types of printed wiring boards, and a storage area is set for each printed wiring board in the nozzle stocker, so that each type of printed wiring board is stored separately. It may be.

  Further, the detection of the presence or absence of the suction nozzle in the nozzle stocker was performed using a nozzle sensor and was performed by a detection-dedicated device, but the detection is based on the presence or absence of acquisition of information from the information recording unit. Also good. Even if the information acquisition device is moved to a preset information acquisition position and performs an acquisition operation, if no information is acquired, the suction nozzle is not accommodated. In this case, the information acquisition device also serves as the nozzle detection device.

  Further, the positioning device or the component holder phasing device for determining the phase of the suction nozzle when it is housed in the nozzle stocker may be constituted by a mark provided on the nozzle side and a mark provided on the nozzle stocker side. For example, a mark is provided on the background forming member of the suction nozzle to define the nozzle holding hole of the nozzle stocker, and at least a portion that is not covered by the separation preventing member when the separation preventing member is located at the release position. The suction nozzle is accommodated in the nozzle stocker so that their positions coincide with each other around the axis of the suction nozzle. When an electronic tag or a two-dimensional code is provided on the background forming member, they may function as nozzle side marks, or a dedicated mark may be provided separately from them. A stocker side mark may be provided in the nozzle holding hole.

  Further, the information recorded in the information recording unit of the suction nozzle is acquired in a state where the suction nozzle is not held by the nozzle holder and returned to the nozzle stocker. It may be acquired in a state held in the memory. In particular, when the information recording unit is configured by an electronic tag, the information acquisition device can acquire information even if it is separated from the electronic tag, so that the degree of freedom of acquisition is high, and acquisition is performed while being held in the nozzle holder. Sometimes it is easy.

  Further, when determining whether to prohibit the use of the suction nozzle 170 based on the bending amount of the suction tube or the luminance of the light emitter, it may be determined at the time of measuring the bending amount of the suction tube and the luminance of the light emitter, It may be performed when a preset condition is satisfied, may be performed during production, or may be performed at a time other than during production. For example, it may be performed every time a part is mounted on one printed wiring board during production, or may be performed at the end of production. For suction nozzles whose use is prohibited, the fact that they are use-prohibited nozzles is recorded in the information recording unit. If the use prohibition release condition is satisfied, the use prohibition information in the information recording unit is deleted and the nozzle is made usable. The use prohibition judgment result based on at least two use prohibition judgment elements that judge the prohibition of use of the suction nozzle, such as the amount of bending of the suction tube, the brightness of the light emitter, the incidence of suction mistakes, the incidence of image processing errors, etc. is prohibited. In some cases, the use of the suction nozzle may be prohibited.

  Furthermore, the set time for determining whether the adsorption tube bending amount has not been measured and the illuminant luminance has not been measured were set to be the same, but they were made different so that they were measured at different times. Also good.

  The production history information can be created in various modes according to history creation conditions or history creation element settings. For example, the production history information is created by combining the component element information, for example, the suction nozzle serial number and the substrate ID. Alternatively, it may be created by combining the component information and the type of circuit board, or may be created by combining a plurality of types of component information. Combinations are set in advance, and a person may select from the combination information, or a person may arbitrarily set them.

  Furthermore, production history information may be instructed to be created by the mounting control computer 230, created on the basis of the host computer 240, transmitted to the mounting control computer 230, and displayed on the display screen 254.

  The produced production history information may be printed on a print medium by a printer. A printer is a kind of output device and outputs by printing. Further, the produced production history information may be stored and saved in a production history information storage unit of a storage means such as a RAM or a database of the host computer.

  Furthermore, the information transmission method between the electronic tag and the information receiving device or the information receiving / writing device is based on the shape and size of the member provided with the electronic tag and the distance from other members provided with the peripheral electronic tag. If the communication target is specified according to the information acquisition conditions or the like, a transmission method having a relatively long communication distance may be adopted.

  In the tray-type component supply device, an information recording unit may be provided in a component tray housing member such as a component tray housing box that houses the component tray. Similar to the case where the information recording unit is provided in the component tray, the information recording unit records information on the component tray or the components accommodated in the component tray. Information about the component tray housing member, for example, shape, dimensions, etc. may be recorded.

  Further, the information recording unit such as a tag chip provided in the suction nozzle may be provided at a position covered by the separation preventing member in a state where the separation preventing member is located at the separation preventing position. When acquiring the information recorded in the information recording unit, the separation preventing member is moved to the open position and retracted from the information recording unit.

  In the above embodiment, the suction error rate is used to determine whether or not the suction nozzle is unusable in the nozzle use prohibition routine and to determine whether or not the suction nozzle is a defective nozzle in the failure possibility nozzle notification routine. The suction error rate was calculated as the ratio of the number of suction mistakes to the total number of suctions of the suction nozzle, but was determined as the ratio of the number of suction mistakes to the number of suctions of the suction nozzle during the set production operation. Although it has not been disclosed yet, it is used for the determination by determining the current error rate (at the time of determination) by the method described in the specification of Japanese Patent Application No. 2002-136944 related to the present applicant. May be. Further, the determination may be made based on whether or not the number of suction mistakes is equal to or greater than the set number. When a defective nozzle is detected in the suction nozzle shortage notification routine, it may be detected based on whether or not the number of suction mistakes is equal to or greater than a set number. The suction nozzle use prohibition condition may be that the number or occurrence rate of image processing errors is equal to or greater than a set value.

  The information recording unit may be provided in any component of the electronic circuit assembly system. For example, when an electronic circuit assembly system is provided with a component accommodating device that accommodates a component that has been removed from the component supply device by the mounting head but has not been attached to the circuit board, the component accommodating device is also a component, If an information recording unit such as an electronic tag is provided, the information recorded on the information recording unit can be used in various ways.

  The part taken out by the mounting head is not suitable for mounting, the part holding position error by the part holder is more than the set value, or the lead is bent greatly. When it is detected by the detection device or the like that it is unsuitable for mounting and used as a discarded component, it is not mounted on the circuit board but is stored in the component storage device. Therefore, for example, as described in the specification of Japanese Patent Application No. 2003-354 related to the present applicant, there are a plurality of internal spaces of a container-shaped storage container as a component storage device, although not disclosed yet. There have been proposed those provided with a plurality of storage chambers partitioned by a partition member, and those provided with a plurality of storage chambers by holding a plurality of small containers. In the plurality of storage chambers, for example, discarded parts are stored separately for each type. The storage chamber may be fixed, and the capacity (volume) of the storage chamber of the component storage device may be changed by changing the position of the partition member or changing the combination of a plurality of types of small containers having different capacities. ), The number of components can be varied, and a component storage device having a storage chamber corresponding to the type and number of components to be mounted can be obtained.

  When changing or setting the configuration of the storage chamber, for example, an operator places a partition member or a small container in the storage container or the holding body based on an instruction from the host computer. In this case, for example, an electronic tag is provided as an information recording unit in the storage container and the holding body, and individual identification information that can individually identify the component storage device is recorded. The operator acquires the individual identification information by the information acquisition device and stores it in the host computer when the partition member or the container is arranged, and the host computer is expected to obtain it by the individual identification information and the arrangement of the partition member or the small container. The capacity, arrangement, etc. of the storage chambers thus stored are associated with each other and stored in the component storage device information memory.

  When the component storage device is used by attaching it to an electronic circuit component mounting machine, the host computer sets the component storage device to be used according to the type of printed wiring board, and instructs the operator to use the electronic circuit component according to the individual identification information. Attach to the mounting machine. After installation, check the storage chamber of the component storage device. For example, a mark is provided on the partition member, and an image capturing device serving as a mark acquisition device is used to acquire the arrangement of the partition member. By design, the actual shape of the storage container, the dimensions, and the like of the storage chamber are obtained. Get capacity, placement, number, etc. The position of the mark is obtained from, for example, the position of the partition member mounting portion formed at a preset pitch in the storage container and the position of the component storage device in the electronic circuit component mounting machine in order to attach the partition member. The obtained capacity and the like of the storage room are compared with the planned capacity and arrangement of the storage room obtained from the individual identification information of the parts storage device, and it is confirmed whether or not the set storage room is provided. If the set storage room is not obtained, for example, a notification is given, and the operator changes the storage room or replaces the parts storage device itself. The same applies to the case where the storage chamber is provided by arranging the small containers. In the case of a small container, an information recording unit that represents the type (identified by shape and size) of the small container is provided, and the small container that is held by the holding body by obtaining information recorded in the information recording unit It is also possible to obtain the type, number, etc. of the storage room to obtain the capacity, arrangement, etc. of the storage chamber.

  If the component storage device set in this way is attached to the electronic circuit component mounting machine, when discarding the unmounted component, the component storage device is mounted according to the type of storage component set for each of the plurality of storage chambers and the layout of the storage chambers. The head is moved to the storage chamber where the parts are to be discarded and stored. At this time, the number of components accommodated in each of the plurality of types of accommodation chambers is counted and stored in the mounting control computer in association with the location of the accommodation chamber and the accommodation components.

  After completion of component mounting on the series of circuit boards, the component storage device is removed from the electronic circuit component mounting machine, and the stored components are processed. Of the stored waste parts, reusable parts are reused and non-recyclable parts are discarded. When the component storage device is removed, the individual identification information of the component storage device is associated with the component storage related information such as the location of the storage chamber, the number and type of the stored components, from the mounting control computer to the host computer. Sent to the host computer. The processing operation of the discarded parts is usually performed by an operator. At this time, for example, the individual identification information of the component storage device to be processed and the information stored in association with it are displayed on the display device. Thus, the worker is notified and the worker can easily perform the work. This is because the arrangement of the storage chamber and the part storage status can be understood. When the information recording unit is configured by an electronic tag capable of writing information, for example, when the component storage device is removed from the electronic circuit component mounting machine, the component storage related information may be stored in the electronic tag. For example, an operator can read information recorded on an electronic tag and use it for work.

  When the information recording unit is a two-dimensional code or a read-only electronic tag, it is not possible to record the number of accommodated parts as change information, but the component accommodating apparatus can record the individual identification information of the component accommodating apparatus. It is possible to use this for confirmation of the configuration and information display at the time of processing the accommodated parts. For example, the operator inputs the individual identification information when processing the accommodated parts, and based on this, the host computer displays the parts accommodation related information on the display device.

When the configuration of the parts storage device is unchanged and the number, capacity, and arrangement of the storage chambers are fixed, the individual identification information of the parts storage device and the capacity, number, layout, etc. of the storage chambers are stored in the information recording unit. For example, when the component storage device is attached to the electronic circuit component mounting machine, the information recorded in the information recording unit is acquired and the type suitable for the mounting machine is recorded. It can be used to check whether the device is a component storage device or to store a component. Alternatively, only the individual identification information is stored in the information recording unit, the individual identification information and the component accommodation related information are stored in association with each other in the computer, and the component accommodation related is obtained from the individual identification information obtained by obtaining the information of the information recording unit. Information may be obtained and used for housing parts. This is the same whether the component storage device has a plurality of storage chambers or only one. If the information recording unit is an electronic tag to which information can be written, information regarding component accommodation acquired during the mounting operation may be written when the component accommodation device is removed.
Once a component storage device that has been used to store a component and has not yet processed the storage component is identified by the type of component stored in the storage chamber, a different electronic circuit component is mounted if possible. The same electronic circuit component mounting machine may be used at different times. In this case, from the individual identification information and the component storage information, the layout of the storage chamber, the type of the component stored, the number of components currently stored in each storage chamber, and the like are obtained, and the number of storage components is added and counted. Can be accurately grasped and processed. By providing the individual identification information, it can be considered that the component storage devices are individually identified and the component storage history is totaled and created.

  When the component storage device includes a plurality of storage container portions to which the partition members are attached, and the storage container portions are a plurality of types of storage container portions having different dimensions and shapes, the types, number, and arrangement of the storage container portions The type of the component storage device can be identified by. Therefore, the type of the component storage device identified by the type of the storage container portion may be recorded in the information recording unit, and the component storage device may be identified by the type based on the reading.

  Furthermore, the component mounting apparatus is not limited to an apparatus that receives and mounts an electronic circuit component by moving the mounting head to an arbitrary position in a plane parallel to the surface of the circuit board by an XY robot. The apparatus may be moved in a direction parallel to one of two orthogonal directions within a plane parallel to the surface of the circuit board. In this case, the circuit board holding device is moved by the holding device moving device in a direction orthogonal to the moving direction of the mounting head in a plane parallel to the surface of the circuit board. These head moving device and holding device moving device constitute a relative moving device that relatively moves the mounting head and the substrate holding device. The component supply device may be moved by the component supply device moving device in the same manner as the holding device moving device, or the component supply unit is provided in a state where the component supply unit is positioned on the movement locus of the mounting head. May be. In addition, as described above, in the component mounting apparatus, a plurality of mounting heads are swung around a common swivel axis by a head swiveling device and sequentially stopped at a plurality of stop positions, and receiving and mounting of electronic circuit components, etc. It is good also as an apparatus which performs. In this case, the plurality of mounting heads and the head turning device are further moved to arbitrary positions within a plane parallel to the surface of the circuit board by the moving device, and the circuit board holding device and the component supply device are provided with fixed positions. You may be made to do.

  Further, the electronic circuit assembly system includes a plurality of mounting units in series as described in the specifications of Japanese Patent Application Nos. 2002-243431 and 2002-338553, which have not been disclosed yet. An electronic circuit assembly system may be used. Each of these mounting units includes a component supply unit, a circuit board holding unit, and a component mounting unit, and the electronic circuit component supplied from the component supply unit is mounted on the circuit board held by the circuit board holding unit by the component mounting unit, An electronic circuit component is mounted on a single circuit board in cooperation with a plurality of mounting units. The plurality of mounting units can be modularized, and the configuration of the electronic circuit assembly system can be easily changed, the mounting unit can be easily replaced, and the like. In addition, in each of the plurality of mounting units, a part of the configuration can be changed according to the type of the target circuit board, and information is recorded on the mounting unit and its components as components of the electronic circuit assembly system. By providing the sections and recording information related to them, it is possible to easily manage the configuration of the assembly system, the mounting units, and the components. A plurality of mounting bodies that are equipped with at least one mounting head and mount components on the circuit board are provided in accordance with the number of mounting heads to be held and can be exchanged with each other. It is. In particular, if identification information capable of individually identifying the mounting unit or the component is recorded in the information recording unit, the mounting unit or the component can be used based on the identification information regardless of when and in what state. Can be managed in an integrated manner, and the components can be used accurately and maintenance can be performed. The mounting unit can be configured in various modes such as the XY robot type, the rotary head type, and a combined type combining them.
