At least one suction nozzle 170 is used to mount the component 54 to 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 entire 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 housed in the nozzle stocker 186. At this time, the suction nozzle recorded on the tag chip 180 of the suction nozzle 170 is used. Based on the information, 170 types of suction are confirmed.
[0081]
As will be described later, when the nozzle stocker 186 is set on the bed 10, nozzle accommodation information that associates the nozzle accommodation position of the nozzle stocker 186 with the suction nozzle information 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, before holding the suction nozzle 170, it is confirmed whether or not the type of the stored suction nozzle 170 matches the type of the suction nozzle 170 to be held.
[0082]
Confirmation of the type of the suction nozzle 170 is performed according to a nozzle type confirmation routine shown in FIG. 12, and the 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. The type of the suction nozzle 170 is confirmed based on whether or not the obtained type of the suction nozzle 170 matches a preset type. At the time of this reading, the reader / writer 200 is located at the lower end position.
[0083]
The reader / writer 200 is moved by the XY robot 132 onto the suction nozzle 170 scheduled to be used, and receives the information recorded on the tag chip 180. This reception is performed while the reader / writer 200 is moved. Thereby, the determination result of S11 becomes YES, and S12 is executed, and it is determined whether or not the type of the suction nozzle 170 is the 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. , S12 is YES, the execution of the routine ends, and the mounting head 130 holds the suction nozzle 170. If the type of the accommodated suction nozzle 170 is not the set type, that is, if it is not the type of the suction nozzle 170 associated with the nozzle accommodation position in the nozzle accommodation information, the determination result in S12 is NO and S13 Is executed, and the fact that the type of the suction nozzle 170 housed in the nozzle holding hole 824 is not the set type, the nozzle housing position, the type of the suction nozzle 170 to be held, and the like are displayed on the display screen 254 and notified. . Thereby, for example, an operator can check the suction nozzle 170 accommodated in the nozzle stocker 186 and replace it, and take appropriate measures.
[0084]
Confirming the type of the suction nozzle 170 when the mounting head 130 holds the suction nozzle 170 is one mode of using the suction nozzle information, but the suction nozzle information is also used in another mode. This will be described in detail later.
[0085]
When the setup change is completed, the work 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 transport device 12, stopped at the mounting operation position by the stopping device, and held by the printed wiring board holding device 14. Then, 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 obtained. The position where the tag chip 36 is provided on the printed wiring board 30 is known by design, and the reader / writer 200 moves 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. Then, the information recorded on the tag chip 36 is received and read. At this time, the reader / writer 200 performs reception at the lower end position.
[0086]
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, so that the horizontal position is determined for each of the plurality of component mounting positions. An error (each position error in the X-axis and Y-axis directions) is obtained.
[0087]
Then, the work of mounting the component 54 on 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 suctions the component 54. After receiving the component 54, the component 54 held by the mounting head 130 is imaged by the component imaging system 190 while the mounting head 130 is being moved to the component mounting position on the printed wiring board 30. By processing the obtained image data in the image processing computer 238, a holding position error of the component 54 is obtained, and the rotation position error is corrected by rotating the mounting head 130 by the head rotation device 136, The positional deviation of the center of the part to be sucked of the component 54 due to the correction of the translational position error and the rotational position error of the center of the part to be sucked of the component 54 and the horizontal position error of the component mounting position of the printed wiring board 30 are determined by the mounting head. It is corrected by correcting the moving position of 130. Then, the mounting head 130 mounts the component 54 on the printed wiring board 30 at the component mounting position.
[0088]
In the present 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 the component trays 110. Is stored. In the present embodiment, the supply number of the components 54 is stored in association with each mounting position of the plurality of feeders 50 and the component trays 110. Then, for each of the plurality of feeders 50 and the component trays 110, it is checked whether or not the number of components 54 to be supplied is insufficient. The replenishment of the parts 54 for the feeder-type parts supply device 18 will be described based on the flowcharts shown in FIGS.
[0089]
In S20 of the parts shortage feeder acquisition routine shown in FIG. 13, it is determined whether the flag F1 is set to 1. When the flag F1 is set to 1, the fact that the mounting of the component 54 on one printed wiring board 30 is completed is stored. The flag F1 is reset to 0 by an initial setting in a basic operation program (not shown), a start of a work of mounting components on one printed wiring board 30, and the like. Therefore, if the mounting of the component 54 to the printed wiring board 30 is in progress, the determination result in S20 is NO and S21 is executed to determine whether the mounting of the component 54 to one printed wiring board 30 is completed. Is determined. This determination is made based on, for example, the execution status of the component mounting program, and is performed, for example, based on whether all the components 54 to be mounted have been mounted on the printed wiring board 30.
[0090]
If the mounting of the component 54 on one printed wiring board 30 has not been completed, the determination result in S21 is NO, and the execution of the routine ends. When the mounting is completed, the determination result of S21 becomes YES, and S22 is executed, and the data of the connectable feeder is deleted. The connectable feeder will be described later.
[0091]
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 increased by one. This counter counts the number of the printed wiring boards 30 on which the components 54 are mounted.
[0092]
Subsequently, S25 is executed, the number of the remaining printed wiring boards 30 on which the components 54 are to be mounted, the type of the components 54 necessary for the number (here, obtained by the component identification code), and the number of the remaining printed wiring boards 30. The number of the components 54 required for mounting all the components for each feeder 50 is obtained. The remaining number of the printed wiring boards 30 is obtained by subtracting the number of the printed wiring boards 30 on which the components 54 have been mounted from the total number of the mounting of the components 54. The number of sheets to be mounted 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 number of sheets to be mounted, reads the number of sheets to be mounted, subtracts the number of sheets to be mounted counted in S24, and subtracts the remaining number of sheets ( (The number of components not mounted) is required. The type of the component 54 required for mounting is obtained from, for example, a component mounting program. Further, the number of components 54 required for mounting on all the remaining printed wiring boards 30 (required supply number) is determined for each feeder 50 of components 54 required for mounting on one printed wiring board 30. Is multiplied by the number of remaining printed wiring boards 30. The number of components 54 necessary for mounting on one printed wiring board 30 for each feeder 50 is obtained from, for example, a component mounting program. Once the type of the component 54 required for one printed wiring board 30 and the number of supplies for each feeder 50 have been 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 and the like are stored in association with the mounting position.
[0093]
Next, S26 is executed, and among the plurality of feeders 50 that are mounted on the feeder support base 48 and are currently used for supplying the components 54, the remaining of the retained A number is required. Whether or not the feeders 50 form a group can be known from, for example, a component mounting program and component mounting related data. For example, the feeders 50 currently used to supply the components 54 form a group from the mounting positions of the feeders 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. It is possible to determine whether or not the components 54 are mounted. The feeders 50 that do not form a group are stored, for example, by their mounting positions.
[0094]
The remaining number of components 54 can be obtained by subtracting the supply number from the initial accommodation number, which is the number of components 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 on the feeder 50, the component information and the feeder information are acquired in association with each other by reading the information of the tag chips 90 and 98, and the mounting position and the feeder information correspond when the feeder 50 is mounted on the feeder support 48. The feeder 50 that does not form a group is retained based on the mounting position and component information obtained and associated with each other from these pieces of information and the mounting position of the feeder 50 that does not form a group. The component information on the component 54 to be obtained is obtained, and the initial number of components 54 stored in the feeder 50 is obtained. The number of supplied components is counted for each feeder 50 in the mounting control computer 230 at the time of mounting components, and the remaining number of components 54 is calculated. Note that once the mounting position of the feeder 50 that does not form a group is acquired, that information is stored and used later. On the contrary, since the feeders 50 forming a group are also known, the information of the feeders 50 may be stored and used later. When the feeder 50 is replaced, the feeder information is updated for the replaced mounting position, and the component information on the component 54 held by the newly mounted feeder 50 is obtained. . Further, 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 48 is supplied from the host computer 240 to the mounting control computer 230 and stored and used. May be done.
[0095]
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. With respect to the components 54 held by the feeders 50 not forming a group, the remaining number calculated in S26 is compared with the number of components 54 required for supply to the remaining printed wiring board 30 determined in S25. If the number is smaller, the component 54 is insufficient, and the feeder 50 is regarded as a component shortage feeder. The component shortage feeder 50 is stored, for example, according to the mounting position. The information may be stored by the feeder ID, or may be stored by the mounting position and the feeder ID. The remaining number of the parts 54 is stored in association with the parts shortage feeder 50.
[0096]
For the component shortage feeder 50, a component supply timing acquisition routine shown in FIG. 14 is executed. The component supply timing acquisition routine is also performed in a state where the component mounting operation is not performed. When there are a plurality of component shortage feeders 50, the component supply timing acquisition routine is sequentially executed for each of the component shortage feeders 50. For example, among the plurality of component shortage feeders 50, the component supply timing acquisition routine is executed in ascending order of the mounting position number. If the parts replenishment time etc. acquisition routine is executed for all of the parts shortage feeders 50, the parts replenishment time etc. acquisition routine is not executed until the mounting of the parts 54 on the printed wiring board 30 is completed next.
[0097]
In S31 of this routine, it is determined whether the number of mountable sheets, that is, the number of the printed wiring boards 30 on which the parts 54 can be mounted by the supply of the parts 54 by the parts shortage feeder 50 is equal to or less than the set number A1. . The mountable number is obtained based on the number of components 54 supplied from the component shortage feeder 50 for one printed wiring board 30 (obtained from a component mounting program) and the remaining number of components 54 in the component shortage feeder 50. .
[0098]
The set number A1 is set to a number that can determine that the supply of the component 54 may be performed by connecting the taping component 58 to the component shortage feeder 50. The connection of the taping component 58 is performed by the operator removing the reel 66 from the feeder 50, removing the taping component 58 remaining on the reel 66 from the reel 66, and starting from the reel 66 at the beginning of the taping component 58 accommodated in the new reel 66. This is performed by connecting the ends of the removed taping component 58, winding the reel around the reel 66, and holding the new reel 66 on the feeder 50. Therefore, even if it is found that the number of the components 54 is insufficient in the state where the number of the components 54 in the feeder 50 is large, the connection operation cannot be performed immediately. If the remaining length of the taping component 58 can be wound on the new reel 66 from above the new tape component 58 already wound, connection can be made, and the set number A1 In the present embodiment, for example, in consideration of the number of components supplied to one printed wiring board 30 of each of the plurality of feeders 50, the component accommodation pitch of the taping components 58, and the like, all the feeders 50 that do not form a group are considered. The number of taping components 58 is set to a number that can be determined to be the length that allows the taping component 58 to be connected so 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 corresponds to the number of mountable components. It is determined whether the number of mountable components is equal to or less than the set number A1. Thus, it is determined whether or not it is time to supply the component 54 by connecting the taping component 58. The determination result of S31 is initially NO, and the execution of the routine ends.
[0099]
The set number A1 is a component supply timing detection value, and may be changed according to the feeder 50. For example, when the component mounting program is created, for each feeder 50, it is set according to the number of components 54 held by the feeder 50 in the taping component 58, the number of supplies, the component accommodation pitch, and the like, and is stored. The set number A1 is read out according to 50 to make the determination. The component supply timing detection value may be set, for example, based on the remaining length of the taping component 58 or the remaining component count instead of the number of the printed wiring boards 30. The set length and the like may be common to the plurality of feeders 50 or may be different.
[0100]
If the mountable number is equal to or smaller 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 smaller than the set number A2. The set number A2 is smaller than the set number A1, and is set to a number that can determine that the remaining amount (remaining length) of the taping component 58 is insufficient for connecting the taping component 58 to the component shortage feeder 50. Have been.
[0101]
The connection work of the taping component 58 is performed by an operator behind the component supply device 18 (on the side opposite to the wiring board transport device 12 side) with the feeder 50 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 operation remains, and the set number A2 is, like the set number A1, a plurality of groups that do not form a group. Taking into account the number of components supplied per printed wiring board of each feeder 50, the component accommodating pitch, and the like, the feeders 50 are set in common, and the remaining amount of the components 58 becomes a length unsuitable for connection work. It is set to a number that can determine that The set number A1 is smaller than the set number A2, and the worker can perform the tape connection operation behind the component supply device 18 when the number of mountable sheets is equal to or less than the set number A1. 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 supplying the component 54 by connecting the taping component 58, that is, the connectable feeder is, for example, Is stored according to the mounting position. Feeder information may also be stored.
[0102]
The set number A2 is a taping component connection timing 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 timing detection value may be set based on, for example, the remaining length of the taping component 58 or the number of remaining components, instead of the number of printed wiring boards 30. The taping component connection timing detection value may be common to a plurality of feeders or may be different.
[0103]
On the other hand, when the remaining length of the taping component 58 is short and is insufficient for the connection work, the number of installable sheets becomes equal to or smaller than the set number A2, the determination result in S32 becomes YES, and S34 is executed. It is determined whether the possible number has become equal to or less than the set number A3. The set number A3 is set to a number smaller than the set number A2, and is set in common to at least one feeder 50 that does not form a group in consideration of the number of components supplied per printed wiring board and the like. The number is set to a value at which it can be determined that replenishment of the component 54 by replacing the feeder 50 may be performed. 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 with the remaining number of the parts 54 as small as possible before the parts 54 are exhausted. -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 the components 54 of the feeder 50 is small and that replenishment by replacement is near. 254 is displayed. It is forewarned that it is almost time for replacement. This notification may be omitted.
[0104]
The set number A3 is a feeder replacement time detection value, and may be set for each of the plurality of feeders 50. In addition, the feeder replacement time detection value may be set based on, for example, the remaining length of the taping component 58 or the remaining number of components, 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.
[0105]
In the present embodiment, the component replenishment time, which is the replenishment time of the component 54 due to the connection of the taping component 58 and the replacement of the feeder 50, is determined according to the number of sheets that can be mounted. For example, even if a plurality of feeders 50 need to be replenished at the same time, the number is set to a number that allows the replenishment operation to be performed with some margin.
[0106]
If the mountable number is equal to or smaller than the set number A3, the determination result of S34 becomes YES and S36 is executed, and it is determined whether the mountable number is 0 or not. The result is YES, S37 is executed, and the mounting work of the component 54 by the electronic circuit component mounting machine is stopped. If the number of installable sheets is not 0, the result of the determination in S36 is NO and S38 is executed to calculate an exchange startable period during which the exchange of the feeder 50 can be started. And at least one of the mounting position. For the component shortage feeder 50, a period during which the replacement work of the feeder 50 can be started is determined. For the feeder 50 whose number of installable sheets is equal to or less than the set number A3 but is not zero, it is difficult to replenish the parts 54 by connecting the taping parts 58, and it is necessary to replace the feeders 50 by replenishing the parts 54. The feeder 50.
[0107]
It is necessary to replace the feeder 50 at a time when the feeder 50 is not supplying the component 54. The replacement work must be started at the non-supply time and be completed by the start of supply. In S38, the supply shortage of the parts shortage feeder 50 is a period from the end of the supply of the parts 54 to the start of the next supply. From the period, a period excluding the period corresponding to the required replacement time, which is the time required for the replacement operation of the feeder 50, at the end of the supply standby period is obtained, and is set as the replacement startable period. Thereby, it is possible to notify the replacement start possible period of the parts shortage feeder 50 at an appropriate time.
[0108]
In the present embodiment, during the supply standby period, during the average component mounting cycle time, the components mounted on the printed wiring board 30 after the replacement required feeder 50 completes the supply of the component 54 and before the next supply is performed. The time is obtained by adding the time required for the operation related to the replacement of the printed wiring board 30 to the time obtained by multiplying the number n by 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 devices 18 and 20, mount the component 54 on the printed wiring board 30, and receive the next component 54 from the component supply device 18 or 20. , Averaged over all components 54 to be mounted. The number n of components is obtained from a component 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, unloading of the printed wiring board 30 having been mounted, loading of the printed wiring board 30 on which the component 54 is to be mounted, imaging of the reference mark 34, and tag chip 36. And the like. As described above, in this 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 the work related to the replacement of the printed wiring board 30 is also reduced. The supply standby period is calculated. The calculated supply standby period and replacement startable period are stored in association with information for specifying the feeder 50 requiring replacement, for example, at least one of the feeder ID and the mounting position of the feeder 50. As described above, the component shortage feeder 50 and the number of sheets that can be mounted are obtained based on the initial storage number and the supply number of the components 54 to be stored in the feeder 50, and the initial storage number, which is information recorded on the tag chip 90, is Used to replenish 54.
[0109]
The connection work of the taping component 58 can be performed even while the component 54 is being mounted on the printed wiring board 30 or not, and the taping electronic circuit component connection routine shown in FIG. 15 is always executed. If there are a plurality of connectable feeders 50, this routine is performed collectively for those feeders 50. In S41 of the taping electronic circuit component connection routine, it is determined whether or not there is a connectable feeder 50. Step S33 of the parts supply timing acquisition routine is executed, and if the connectable feeder 50 is acquired and stored, the determination result of S41 becomes YES and S42 is executed, and the connectable feeder 50 is displayed on the display screen 254. Will be 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 has been completed. When the worker performs the connection work of the taping component 58 according to 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 the operation has been completed, the determination result in S43 becomes YES and S44 is executed, and the data indicating that it is a connectable feeder, display, and the like are deleted for the feeder 50 for which connection has been completed. When the taping parts 58 are connected, the carrier tapes 56 and the cover tapes 62 of the two taping parts 58 connected to each other are connected to each other. 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 the description is omitted.
[0110]
When connecting the taping component 58, the operator inputs the mounting position of the feeder 50 holding the taping component 58, and transmits the information recorded on the tag chip 90 contained in the carrier tape 56 to the portable reader / writer 248. And sends it to the mounting control computer 230. The component accommodating recess 60 of the carrier tape 56 in which the tag chip 90 is accommodated is covered with the cover tape 62, but is made of synthetic resin, so that electromagnetic waves are not blocked and information of 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 instead of the feeder information and the component information previously stored in association with each other for the same feeder 50. Further, the number of supplied components stored corresponding to the mounting position is reset to zero. Therefore, as a result of calculating the number of remaining components in the feeder 50 in S26 of the component shortage feeder acquisition routine, the connected feeder 50 is prevented from being a component shortage feeder in S27. This component supply number 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, as described later. After the connection, the supply number of the components 54 remaining in the taping component 58 that is currently supplying the components 54 is counted. If the mounting position of the feeder 50 is input when the connection of the taping component 58 is executed, the execution of the connection is stored in association with the mounting position. Further, the number of remaining components and the number of supplied components at the time of connection completion input are stored. Thus, for example, even if a series of mounting operations is completed before the tag chip 90 reaches the component supply unit, execution of connection is stored, the number of remaining components at the time of input of connection completion, and the number of supplied components. The number of components supplied in the feeder 50 can be obtained from the number of components supplied after the connection is completed. The remaining number of components and the like are erased when the tag chip 90 reaches the component supply unit and is detected, and the connection of the taping component 58 is detected. The number of components supplied is not reset at the time of input of connection completion, but the number of components supplied at that time is stored. Thereafter, each time a component is supplied, the number of components supplied is compared with the initial accommodation number, and the tag chip 90 reaches the component supply unit It may be detected whether or not the operation has been performed. At this time, when the tag chip 90 reaches the component supply unit, the component supply number is reset to zero. In addition, by storing the connection completion, it is possible to avoid being a component shortage feeder.
[0111]
The replenishment of the parts 54 by replacing the feeder 50 will be described based on the feeder replacement routine shown in FIG. If a feeder requiring replacement occurs and a replacement startable period is obtained, a feeder replacement routine is executed. This routine is executed separately for each of the exchange-required feeders 50 for which the feeder exchange startable period has been acquired in S38 of the parts supply timing etc. acquisition routine. In the present embodiment, a plurality of feeder replacement routines are provided. This routine is performed both during the work of mounting the component 54 on the printed wiring board 30 and during the non-work. Each of the plurality of feeder replacement routines has the same configuration, and one of them will be representatively described.
[0112]
First, in S51, it is determined whether the flag F2 is set. When the flag F2 is set, the fact that the feeder replacement work has been started is stored. If the replacement work has not been started and the flag F2 has been reset, the determination result in S51 is NO, and S52 is executed, and it is determined whether the flag F3 is set. When the flag F3 is set, the fact that the supply of the component 54 to one printed wiring board 30 by the replacement feeder 50 is completed is stored.
[0113]
If the flag F3 has been reset, the determination result in S52 is NO, and S53 is executed, and it is determined whether or not the component supply by the replacement required feeder 50 has been started. This determination is made based on the execution status of the component mounting program. If the component supply by the replacement required feeder 50 is started, the determination result of S53 becomes YES and S54 is executed, and the replacement of the component 54 by the replacement required feeder 50 is performed. It is determined whether the supply has been completed. Until the supply ends, the determination result in S54 is NO, and the execution of the routine ends.
[0114]
When the supply of the component 54 to one printed wiring board 30 by the replacement required feeder 50 is completed, the determination result in S54 becomes YES, the flag F3 is set in S55, and then S56 is executed. Is displayed on the display screen 254. The displayed time is reduced over time. The display screen 254 also displays the feeder ID of the replacement feeder 50, such as a number, a type, a mounting position, and a type of the component 54 held in the feeder 50. The operator can see the display and start the replacement. If the period remains, the exchange of the feeder 50 can be started, and if the period becomes 0, the exchange operation cannot be started.
[0115]
Next, S57 is executed, and it is determined whether the time T1 has elapsed. The time T1 represents a period during which the exchange can be started, and the elapse of the period T1 indicates that the period during which the exchange can be started. The determination result in S57 is NO until the time T1 elapses, and it is determined whether S58 is executed and the replacement is started. This determination is made, for example, based on whether the feeder 50 has been removed from the feeder support 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 and the feeder 50 has not been removed from the feeder support base 48 and the replacement has not been 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, and S53 to S55 are skipped and S56 is executed.
[0116]
If the replacement of the feeder 50 is started before the time T1 has elapsed, the determination result in S58 becomes YES, and S59 is executed, the flag F2 is set, and the flag F3 is reset. The display screen 254 displays the feeder ID, the mounting position, the type, and the like of the exchange-required feeder 50 together with the time indicating the exchange startable period. The feeder 50 is detached from the feeder support 48, and another feeder 50, on which a new reel 66 containing components 54 of the same type is set, is attached to the feeder support 48. At this time, as in the case of the setup change, the mounting position is input, and the information recorded on the tag chip 98 provided in the feeder 50 is received by the portable reader / writer 248 and sent to the mounting control computer 230 to be exchanged. It is confirmed whether or not the type of the component 54 held by the feeder 50 matches the type set for the supply at the mounting position. Further, from the feeder information stored for the newly mounted feeder 50, the component information on the component 54 accommodated in the feeder 50 is obtained, and the initial accommodation number and the like are obtained.
[0117]
When the flag F2 is set, the next time S51 is executed, the determination result is YES and S60 is executed to determine whether or not the replacement is completed. When the replacement of the feeder 50 is completed, the operator inputs the completion of the replacement using the input device 244. However, if the replacement is not completed, the determination result of S60 is NO and S61 is executed, and the T2 time is set. It is determined whether or not it has elapsed. The time T2 represents the supply standby period, and if the time T2 has not elapsed, the determination result in S61 is NO. The determination of the completion of the replacement may be made by detecting the feeder 50 by the feeder detecting device 246, for example. In this case, the feeder detection device 246 and the like constitute a replacement completion detection unit.
[0118]
If the replacement of the feeder 50 is completed before the time T2 elapses, the determination result in S60 becomes YES and S62 is executed, the feeder exchange data is deleted, and the flag F2 is reset. The feeder replacement data is at least one of the feeder ID (number) of the replacement required feeder 50 and the mounting position, a replaceable period, and the like, and is the data stored in S38 of the parts supply timing etc. acquisition routine S38. This data erasure eliminates the need for replacement feeder 50 and prevents the feeder replacement routine from being executed. Further, based on the completion of the replacement, the number of components 54 supplied by the feeder 50 is reset to zero. The count value of the counter provided corresponding to the mounting position is reset.
[0119]
If the replacement of the feeder 50 is started but not completed before the time T2 elapses, the determination result in S61 becomes YES and S63 is executed, and the mounting work of the component 54 by the electronic circuit component mounting machine is stopped. Can be The cause of the stop is displayed on the display screen 254 and is notified.
[0120]
If the time T1 has elapsed without the exchange of the feeder 50 being started, that is, if the exchange startable period has elapsed, the determination result of S57 becomes YES, S64 is executed, and the flag F3 is reset. Therefore, the determination results in S51 to S53 are NO until the next component supply is started for the replacement required feeder 50. If the exchange startable period has elapsed without the start of the exchange operation of the feeder 50, it is displayed and notified that the exchange is not possible until the next exchange becomes possible. You may do so. An alarm may be issued. In this case, the part of the control device 24 that reports the non-replaceable period constitutes the non-replaceable period reporting unit.
[0121]
As described above, the component shortage feeders 50 are acquired for the feeders 50 that do not form a group, and the components 54 are supplied by connecting the taping components 58 or replacing the feeders 50. On the other hand, for the feeders 50 forming a group, the next device function is executed, and if the parts 54 are still insufficient, the parts 54 are replenished by executing the next designation instruction routine shown in FIG. I have.
[0122]
In the present embodiment, the next designation instruction routine is executed during the non-mounting work of the component 54. In the present embodiment, the process is executed once for all the feeders 50 currently used for supplying the components 54, for example, in ascending order of the mounting position number on the feeder support 48. It may be executed in the order in which the components 54 are mounted. The feeder 50 currently 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 feeders 50 that are currently used for supplying the parts 54 and form a group, and the next designation instruction routine for the detected feeder 50 is provided. May be executed. Further, the next designation instruction routine may be performed during the work of mounting the component 54 on one printed wiring board 30.
[0123]
In S71 of the next designation instruction routine, first, it is determined whether the feeder 50 is a feeder 50 forming a group. The feeders 50 forming a group are obtained based on a component mounting program, component mounting related data, and the like, similarly to the case where the feeders 50 forming no group are obtained in S26 of the component shortage feeder obtaining routine. If the feeders 50 are not a group of feeders 50, the determination result in S71 is NO, and the execution of the routine ends.
[0124]
If the feeders 50 are a group of feeders 50, the determination result of S71 is YES and S72 is executed, and the order in which the feeder 50 finally supplies the component 54 among the plurality of feeders 50 of the same group is determined. 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. For the mounting positions of the feeders 50 determined to form a group, it is determined whether the supply order set in the component mounting related data is the last. If not, the determination result in S72 is NO. And the execution of the routine ends.
[0125]
As for the feeders 50 forming a group, the components 54 are extracted from the feeders 50 until the remaining number becomes zero. For example, if the mounting head 130 performs the operation of taking out the component 54 and cannot receive the component 54 from the same feeder 50 a plurality of times, for example, two times in succession, it is determined that the component 54 is gone, and if the component runs out. , From the feeder 50 in the next order. From the mounting position and the component mounting related data of the feeder 50 in which the component has run out, a feeder 50 that is in the same group as the feeder 50 and whose feed order is later than the feeder 50 in which the component run out has been obtained, Next, the feeder 50 that supplies the component 54 is set, and the mounting position of the feeder 50 associated with the component mounting position in the component mounting program is changed to the feeder 50 that supplies the component 54 instead of the feeder 50 that has run out of components. It is rewritten to the mounting position.
[0126]
As for the feeders 50 forming a group, the components 54 are supplied until the components run out. Therefore, the replenishment of the components 54 is performed by replacing the feeder 50. May be. In this case, as in the case of the feeders 50 that do not form a group, for example, the fact that it is the replenishment time due to the connection of the taping component 58 may be notified based on the number of sheets that can be mounted. However, in the case of the feeders 50 forming a group, even though the feeder 50 is notified that the feeders are connectable, the taping component 58 is not connected, and the number of installable feeders 50 by supplying the components 54 of the feeder 50 becomes zero. However, the operation of the electronic circuit component mounting machine is not stopped, and the feeder 50 in the next group in the same group supplies the component 54.
[0127]
If the feeder 50 is the last feeder 50 in the group, the determination result of S72 becomes YES, and S73 is executed, and the remaining number of the parts 54 in the feeder 50 is calculated. This calculation is performed in the same manner as in S26 of the parts shortage feeder acquisition routine. Next, S74 is executed to determine whether the component 54 is insufficient. This determination is based on the remaining number of mounted components of 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 larger than the required number of supplies and the parts 54 are not insufficient, the determination result in S74 is NO and the execution of the routine ends.
[0128]
On the other hand, if the component 54 is insufficient, the determination result in S74 becomes YES, and S75 is executed, and the next designation instruction is displayed on the display screen 254. If the feeders 50 belonging to the same group as the last feeder 50 in the supply order and all the feeders 50 except the last feeder 50 in the supply order have finished supplying the parts 54 held respectively, the group Among them, an instruction to specify a component to which the component 54 is to be supplied next is displayed on the display screen 254. All the feeders 50 belonging to the group formed by the feeders 50 lacking the parts 54 and having a supply order other than the last, that is, the mounting positions, feeder IDs, supply order, and supply parts 54 of all the feeders 50 in which the parts have run out. The type and the like are also displayed.
[0129]
The operator determines the feeder 50 to which the component 54 is to be supplied next in accordance with the next designation instruction and the like, and inputs the feeder 50 through the input device 244. This designation is performed, for example, by designating the mounting position of the feeder 50 on the feeder support 48. In the present embodiment, the components 54 are supplied to the feeders 50 belonging to the group until the remaining number of the components 54 becomes zero. Therefore, the operator specifies the feeder 50 to supply the component 54 next by the mounting position, and replaces the feeder 50 mounted at the mounting position to supply the component 54. At this time, the operator 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 in the group, and designates the supply order. The supply order is designated even if only one feeder 50 has been exchanged, and the mounting position and supply order at which the feeder 50 has been exchanged 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 supply order currently stored, the data is rewritten, and if the supply order is the same, the data is left as it is. The operator also inputs the completion of the next designation after completing the parts supply and the like.
[0130]
Then, if a component runs out in the feeder 50 in the last supply order among the plurality of feeders 50 in the group, another feeder 50 in the same group supplies the components 54 according to the newly stored supply order. When the exchange is performed for only some of the feeders 50 and the supply order is specified for only some of the feeders 50, the mounting position where the feeder 50 and the feeder 50 other than the last in the supply order are mounted. Are deleted.
[0131]
In addition, among the feeders 50 in the group, the feeders 50 whose supply order is other than the last may be replaced even if the feeder 50 whose supply order is the last does not become a component shortage state. . For example, if the feeder 50 in the group is out of components and the supply order of the feeders 50 is not the last, information about the feeder 50, the mounting position, information about the components 54 to be stored, and the like are displayed on the display screen 254. Inform that the exchange is possible. Alternatively, the operator may find the feeder 50 with the missing parts and replace it. The input of the supply order may be performed. In this case, S75 is executed in the next designation instruction routine, and the replenishment of the parts 54 may be completed before the next designation display is displayed. In this case, the operator may replace the parts by replacing the feeder 50, for example. Next designation completion is input, such as completion of replenishment of 54, supply order or designation of supply order.
[0132]
In any case, when the feeder 50 is replaced, input of the mounting position and reception of information recorded on the tag chip 98 of the feeder 50 are performed, 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. Thus, for the feeder 50 newly mounted on the feeder support 48, the initial number of components 54 to be newly obtained is obtained. Further, the feeder 50 is provided in association with the replaced mounting position, and the count value of the counter for counting the number of supplied components is reset to zero.
[0133]
Although the description using the flowchart is omitted, the component 54 is taken out from the designated feeder 50 in accordance with the next designation. If the designation is not made, the electronic circuit component mounting machine stops operating due to a component shortage occurring in the feeder 50 of the group of feeders 50 in the last supply order.
[0134]
When the feeder 50 is replaced and the supply order is input, if the data in which the supply order is the last for one of the at least one exchanged feeder 50 is set, the next designation instruction routine is performed for the feeder 50. Is executed, the determination in S72 becomes YES, the next designation instruction is displayed, and the replacement of the feeder 50 allows the parts 54 to be further supplied. 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 component 54 (the supply order is later), the feeder 50 that is currently supplying the component 54 becomes the last feeder. It may be.
[0135]
As described above, in the new taping component 58, the tag chip 90 is accommodated in the component accommodating recess 60 at the tip end. 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 currently supplying the component 54, as the taping component 58 is sent, This leads to the component supply unit, and it is necessary to prevent the component from being mounted on the printed wiring board 30.
[0136]
Therefore, when the completion of the connection is input when the taping component 58 is connected, the component information and the like associated with the feeder information in the host computer 240 are the information recorded on the tag chip 90 accommodated in the new taping component 58. And the remaining number of the components 54 at the time of input of the connection completion, that is, the remaining number of the components 54 in the taping component 58 which is currently supplying the components 54, is obtained and stored. Is done.
[0137]
From the remaining number of the components 54, the approximate number of components 54 supplied until the tag chip 90 reaches the component supply unit can be obtained. The connection portion of the taping component 58 is detected by the connection portion detection device, the number of components 54 located between the connection portion detection position and the component supply portion is obtained, and the components 54 until the tag chip 90 reaches the component supply portion. May be obtained.
[0138]
Each time the component 54 is supplied, it is monitored whether the number of components 54 supplied after the connection completion input of the taping component 58 has reached the number estimated that the tag chip 90 has reached the vicinity of the component supply unit. When the mounting head 130 is near, when the mounting head 130 receives the component 54 from the feeder 50, the movement path of the mounting head 130 such that the reader / writer 200 passes over the component receiving recess 60 located in the opening 84 of the cover 80. Is set.
[0139]
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. And 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 coinciding with the feeder 50, and if the tag chip 90 is in the opening 84, , The reader / writer 200 can perform communication and receive information. The reader / writer 200 performs reception while moving. In addition, the reader / writer 200 is moved to the lower end position during reception. Since the taping component 58 held in the adjacent or close feeder 50 is lowered to a distance where there is no risk of wireless communication with the tag chip 90, the component 54 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.
[0140]
As described above, the taping component 58 is covered with the metal cover 80, and the tag chip 90 does not reach the inside of the opening 84, but is located on the upstream side of the component supply section in the carrier tape feeding direction, and is covered with the cover 80. In this state, no information is read by the reader / writer 200, and the tag chip 90 is not erroneously determined to be located in the opening 84.
[0141]
If no communication is performed, the component 54 is housed in the component housing recess 60 located in the opening 84, and the mounting head 130 takes out the component 54. When the communication is performed, the tag chip 90 is in the opening 84, and the taping component 58 is sent by the carrier tape feeder 72 to the set pitch based on the detection of the tag chip 90. This pitch is set to a pitch that ensures that the tag chip 90 retreats from the opening 84 and the component accommodating recess 60 in which the component 54 is accommodated is located in the opening 84. After the feeding, the mounting head 130 takes out the component 54. Note that the type of the component 54 can be confirmed again by acquiring the component information by communicating with the tag chip 90 located in the opening 84, for example. As described above, the information recorded in the tag chip 60 at the time of the connection work of the taping component 58 is acquired using the portable reader / writer 248, and the type of the component 54 is confirmed. You can check it here.
[0142]
By sending the taping component 58 based on the detection of the tag chip 90 in this manner, it is possible to prevent the tag chip 90 from being taken out of the carrier tape 56 by the mounting head 130 and mounted on the printed wiring board 30. Furthermore, it is determined whether or not the tag chip 90 has been erroneously taken out based on the image data of the component 54 by the component imaging system 190. As described above, in the present embodiment, the tag chip holder 92 has a cross-sectional shape distinctly different from that of the component 54, and the shape of the image obtained by imaging is different from the cross-sectional shape of the tag chip holder 92. If the shape is the same, it is determined that the tag chip 90 has been taken out, and the tag chip 90 is ejected to an unillustrated ejection device, and the component 54 is taken out of the feeder 50 again. The reading of the information of the tag chip 90 and the detection of the tag chip 90 based on the imaging are 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 component 54 in the feeder 50 is reset to zero. Further, information indicating that the taping component 58 has been connected, the remaining component count, and the component supply count at the time of connection completion input are deleted.
[0143]
Although the description is omitted, the supply of the components 54 in the tray-type component supply device 20 is performed by replacing the component trays 110 in the present embodiment, and if there is a component tray 110 in a group, the next designation is performed. The replacement and the next designation are performed in the same manner as in the feeder-type component supply device 18.
[0144]
The use of the 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 housed in the nozzle stocker 186, (c) Creation of production history information, (d) Assembly of the electronic circuit Notification of the shortage of the suction nozzles 170 necessary for the operation, (e) prohibition of the use of the suction nozzles 170 that cannot be used, (f) guidance for maintenance of the suction nozzles 170, (g) notification of the nozzles with the possibility of failure, ( h) The suction nozzle 170 is used for supporting the storage operation of the suction nozzle 170 in the nozzle stocker 186.
[0145]
The suction nozzle information is used at the time of production preparation, at the start of production, during production, and at least one time after production. Hereinafter, the use of the suction nozzle information at each time will be described.
In the present electronic circuit component mounting machine, the mounting of the component 54 on one type of printed wiring board 30 is performed for a predetermined number of printed wiring boards 30, and during the production preparation, the next production is performed. Nozzle stockers 186 accommodating suction nozzles 170 corresponding to the type of printed wiring board 30 to be mounted, that is, nozzle stockers 186 accommodating suction nozzles 170 corresponding to the type and number of components 54 mounted on printed wiring board 30, are attached to 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.
[0146]
If the nozzle stocker 186 is actually mounted on the stocker mounting portion 280, it is removed from the stocker mounting portion 280. The nozzle stocker 186 is a nozzle stocker 186 that houses the suction nozzle 170 used to mount the component 54 on the printed wiring board 30 whose production has been completed. The suction nozzle 170 held by the mounting head 130 is attached to the nozzle stocker 186. After being returned, it is removed.
[0147]
The suction nozzle 170 held by the mounting head 130 is returned to the nozzle holding hole 284 in which the suction nozzle is housed in principle. At this time, the presence or absence of the suction nozzle 170 in the nozzle holding hole 284 is checked. This confirmation is always performed when the suction nozzle 170 is returned to the nozzle stocker 186 and accommodated therein. It is confirmed whether or not the nozzle holding hole 284 is empty, so that interference and damage between the suction nozzles 170 are avoided. When 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 prevention member 286 is located at the separation prevention position, the nozzle presence / absence detection member 286 The part that is not covered is moved to a position where light is irradiated, and the 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, which are set in advance for each of the nozzle accommodating portions and recorded on the tag chip 320, and recorded on the tag chip 320 when the nozzle stocker 186 is attached. The received stocker information is obtained together with the nozzle accommodation position and the like.
[0148]
If the nozzle holding hole 284 is empty, the suction nozzle 170 is housed in the nozzle holding hole 284 and returned. The holding and release of the suction nozzle 170 by the nozzle holder 168 will not be described in detail, but as described in JP-A-11-220294, the nozzle holder 168 and the nozzle holder 282 Is performed in combination with the relative movement in the axial direction of the suction nozzle 170 and the separation prevention and release of the suction nozzle 170 by the separation prevention member 286.
[0149]
The suction nozzle 170 is returned to the phase when the suction nozzle 170 is taken out from the nozzle holding hole 284, and the phase of the engagement concave portion 270 and the phase of the positioning pin 285 match. The phase at the time of removal is stored, for example, by the value of an encoder that detects the cumulative rotation angle (rotation angle) of the head rotation device 136. Therefore, when the suction nozzle 170 is lowered and housed in the nozzle holding hole 284, the positioning pin 285 is fitted into the engagement recess 270, and the suction nozzle 170 is housed in the nozzle holding hole 284 at a certain phase, and is separated. Even when the prevention member 286 prevents the suction nozzle 170 from separating 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.
[0150]
If the suction nozzle 170 is already housed in the nozzle holding hole 284, for example, based on the nozzle housing information, whether or not there is another nozzle holding hole 284 that is scheduled to be empty in the nozzle stocker 186 Are found, and there is a scheduled nozzle holding hole 284 that is empty, and if it is actually empty, the suction nozzle 170 is housed in the nozzle holding hole 284. If there is no nozzle holding hole 284 in the nozzle accommodation information, the fact is displayed on the display screen 254 and the operator is notified. The presence / absence of the suction nozzle 170 is detected for all the nozzle holding holes 284 of the nozzle stocker 186, an empty nozzle holding hole 284 is searched, and if there is an empty nozzle holding hole 284, the nozzle is returned to there. Is also good. Confirmation of the presence or absence of the suction nozzle 170 in the nozzle holding hole 284 performed when returning the suction nozzle 170 to the nozzle stocker 186 and processing based on the result are performed by changing the suction nozzle 170 held by the mounting head 130 for setup change to the nozzle. The same operation is performed when returning the suction nozzle 170 to the nozzle stocker 186 other than when returning to the stocker 186. In some cases, it is not necessary to confirm the presence or absence of the suction nozzle 170. In such a case, the suction nozzle 170 is housed 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.
[0151]
The type and number of the suction nozzles 170 necessary for mounting the component 54 are preset according to the type of the printed wiring board 30 and are displayed on the display screen 265. 186. The operator arbitrarily accommodates the suction nozzle 170 in the plurality of nozzle holding holes 284 of the nozzle stocker 186, but accommodates the suction nozzle 170 such that the phase becomes a preset phase. Since the separation preventing member 286 is kept at the release position and is housed so that the positioning pin 285 provided in the nozzle holding hole 284 is fitted into the engagement recess 270 provided in the background forming plate 176. is there. In the present embodiment, a plurality of sets, for example, two sets of suction nozzles 170 required for mounting the component 54 are stored in the nozzle stocker 186. At the time of use, some of the suction nozzles 170 are put on standby for use as spare nozzles. It is not essential to set a plurality of suction nozzles 170, and only one set may be accommodated. Further, one suction nozzle 170 of the same type as the suction nozzle 170 used for mounting may be accommodated as a spare nozzle one by one.
[0152]
Note that 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 of them is housed 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 with a small number of suction errors or a small number of image processing errors can be preferentially used. The part of the host computer 240 that displays the suction nozzle information on the display screen 265 constitutes a nozzle accommodation work support part, which is a type of information utilization part. The suction nozzle 170 is accommodated in the nozzle stocker 186 in preparation for the setup change, and the operator replaces the nozzle stocker 186 in accordance with the setup change instruction.
[0153]
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 receives the information recorded on the tag chip 320 provided on the nozzle stocker 186. Stocker information about the nozzle stocker 186 attached to the 280 is obtained. Based on this information, it is determined whether or not the nozzle stocker 186 is of a type for a printed wiring board to be produced next, and the type is set according to the type of the printed wiring board 30 in the component mounting program. If it does not match the type of the nozzle stocker 186, it may be notified and replaced.
[0154]
If the nozzle stocker 186 is mounted on the nozzle mounting section 280, the suction nozzle 170 housed in the nozzle stocker 186 is checked. The reader / writer 200 is moved to the nozzle stocker 186 by the XY robot 132 and lowered to the lower end position, and receives the information recorded on the tag chip 180 of the suction nozzle 170.
[0155]
The information receiving / writing position is set for each of the plurality of nozzle storage units 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 a preset distance and the phase with respect to the engaging recess 270 is a preset phase. In addition, since the suction nozzle 170 is phase-determined by the phase determination device and is housed in the nozzle holding hole 284 at a fixed phase, the position of the tag chip 180 in a state where the suction nozzle 170 is housed in the nozzle holding hole 284 is 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 on the tag chip 180. The information receiving / writing position is an information receiving / recording position, an information obtaining / writing position or a communication position.
[0156]
If the suction nozzle information is received by communication with the tag chip 180 of the reader / writer 200, the information is stored in the nozzle accommodation information memory provided in the RAM 224 in association with the nozzle accommodation position which is the position of the nozzle holding hole 284 in the nozzle stocker 186. Let me do. In this case, the nozzle accommodation position may be a coordinate value that defines the nozzle accommodation position, and the nozzle accommodation portion identification information or the nozzle accommodation portion identification information that is associated with the coordinate value on a one-to-one basis. It may be a code. When communication is not performed with the tag chip 180 even when the tag chip 180 is moved to the information receiving / writing position and information cannot be obtained, for example, the cause is that the suction nozzle 170 is not housed in the nozzle holding hole 284. Alternatively, the suction nozzle 170 is housed 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 housed, the housing of the suction nozzle 170 with the wrong position of the tag chip 180 and the housing position of the suction nozzle 170 are displayed. Will be notified. In accordance with this, the worker checks the designated storage position, performs appropriate processing such as replacing the suction nozzle 170, and obtains information on the suction nozzle 170 again by communicating with the tag chip 180 for the storage position. , So that accommodation information about the accommodation position can be obtained. Further, when the suction nozzle 170 is not detected by the nozzle presence / absence sensor 330 and the suction nozzle 170 is not housed in the nozzle holding hole 284, information to that effect is stored in association with the nozzle housing position.
[0157]
By communicating with the tag chip 180, the suction nozzle information recorded on the tag chip 180 is obtained, the suction nozzle information is associated with the nozzle housing position to form nozzle housing information, and is stored in the nozzle housing 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 point, the mounting head 130 does not yet hold the suction nozzle 170, and suction nozzle information associated with the nozzle storage position is obtained for all the suction nozzles 170 stored in the nozzle stocker 186 in advance. The acquisition of the suction nozzle 170 existing in the electronic circuit component mounting machine and the acquisition of the suction nozzle 170 accommodated in the nozzle stocker 186 are performed. Note that the presence / absence of the suction nozzle 170 is detected by the nozzle presence / absence sensor 330 prior to communication with the tag chip 180, and when the suction nozzle 170 is detected, the reader / writer 200 may perform communication with the tag chip 180. Good.
[0158]
If the nozzle accommodation information is obtained, it is determined whether or not the bending amount of the suction tube 174 and the luminance of the background forming plate 176 have been measured for all the accommodated suction nozzles 170. The luminance of the background forming plate 176 is measured when the suction nozzle 170 is of a type in which the background forming plate 176 functions as a light emitter. The above determination is made based on whether or not the bending amount and the luminance are recorded in the suction nozzle information, and whether or not the difference between the recording date and time and the current time is within a set time. If the suction nozzle 170 is of a type in which the background forming plate 176 does not function as a light emitting body, 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 the set time. . The type of the suction nozzle 170 can be known from the suction nozzle information.
[0159]
This determination is performed according to the suction tube bending amount / luminous body luminance measurement presence / absence display routine shown in FIG. 21, and is sequentially performed for all the suction nozzles 170 housed in the nozzle stocker 186 in a preset housing order. First, in S81, it is determined whether or not the suction nozzle 170 has the background forming plate 176 functioning as a light emitter.
[0160]
If the background forming plate 176 is the suction nozzle 170 functioning as a light emitter, the determination result in S81 becomes YES and S82 is executed, and it is determined whether 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 measuring the amount of bending of the suction tube 174, the luminance of the light emitter is also measured. Therefore, either the bending amount and the luminance are measured, or neither is measured.
[0161]
If both of them are measured, the determination result in S82 becomes YES and S84 is executed, and it is determined whether or not the bending amount or the like is measured for all the suction nozzles 170 accommodated in the nozzle stocker 186. It is determined whether the operation has been performed. Until the determination has been made for all, the determination result in S84 is NO, and the execution of the routine ends.
[0162]
On the other hand, if neither the bending amount nor the luminance is measured, the determination result of 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 the provided unmeasured nozzle storage unit.
[0163]
If the suction nozzle 170 does not function as the illuminator of the background forming plate 176, the determination result in S81 is NO, and S86 is executed to determine whether the bending amount is measured. This determination is performed as described above, and if measured, the determination result in S86 is YES and S84 is executed. If the amount of bending has not been measured, the determination result in S86 is NO, and S83 is executed, so that the unmeasured nozzle information is stored.
[0164]
If it is determined whether or not the bending amount or the like has been measured for all the suction nozzles 170 accommodated in the nozzle stocker 186, the determination result of S84 becomes YES and S85 is executed, and the determination result becomes Is displayed. If the data of the unmeasured nozzle is stored in the unmeasured nozzle storage unit, the information of the unmeasured nozzle is displayed. For example, the serial number of the unmeasured nozzle and the nozzle housing position are displayed on the display screen 254. Be informed. If there is no unmeasured nozzle, the fact is displayed and the operator is notified. Further, the notification may be made by an audio device.
[0165]
If the display screen 254 displays the suction nozzle bend amount and the suction nozzle 170 for which the suction tube bend amount is not measured for which the bent amount of the suction tube and the luminance of the luminous body are not measured, the operator sees it. Then, the serial number of the suction nozzle 170 for measuring the bending amount of the suction tube and the measurement instruction are input using the input device 244.
[0166]
In the present electronic circuit component mounting machine, if a measurement instruction such as the amount of bending of the suction tube is given, the suction tube bending amount / luminous body luminance measurement routine shown in FIG. 22 is executed and measurement is performed. The measurement is sequentially performed on at least one suction nozzle 170 specified by the operator, and first, in S91, it is determined whether or not only the bending amount is 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 determined. Is NO and S92 is executed to measure the bending amount of the suction tube and the luminance of the luminous body.
[0167]
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 at which the suction nozzle 170 for which measurement is instructed is stored, and holds the suction nozzle 170.
[0168]
The amount of bending of the suction tube 174 is measured by, for example, imaging the suction end surface, which is the distal end surface of the suction tube 174, using a component camera of the component imaging system 190, as described in JP-A-2002-368489. You. For example, the suction nozzle 170 is moved to the component imaging position, and the suction end surface is imaged at a plurality of, for example, two imaging positions having different positions around the nozzle rotation axis. At the time of imaging, the background forming plate 176 as a light emitting body emits light, irradiates the component 54 with light, and a projected image of the component 54 is formed. Then, 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 obtained from the two images and the two imaging positions of the suction end face. From the center position of the image of the suction end face at the image pickup position, the amount of bending of the suction pipe 174, which is the displacement amount of the suction end face with respect to the nozzle rotation axis, is obtained. The two imaging positions are, for example, positions separated by 180 degrees around the nozzle rotation axis.
[0169]
Further, the luminance of the luminous body is measured based on an image of the luminous body obtained at the time of imaging the suction end face. This is 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 light emitting body, and is a predetermined detection area, for example, an annular detection area centered on the nozzle rotation axis. The average value or standard deviation of the luminance of each pixel at is calculated. These average values or standard deviations are obtained based on the image data obtained at the two imaging positions, and the average value is obtained as the luminance of the luminous body.
[0170]
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 having completed the measurement is returned to the nozzle stocker 186. As described above, the suction nozzle 170 is returned to the nozzle holding hole 284 from which it has been taken out. Before returning, the suction nozzle 170 determines whether or not the nozzle holding hole 284 is empty. The interference and damage between the suction nozzles 170 are avoided. Further, the suction nozzle 170 is returned in the phase set at the time of extraction, which is the phase at the time of removal.
[0171]
After the suction nozzle 170 is accommodated 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.
[0172]
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, and S94 is executed, and the bending amount of the suction pipe 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.
[0173]
The above is the production preparation, and then the production is started. If there is a possibility that the operator changes the arrangement of the suction nozzles 170 accommodated in the nozzle stocker 186 after the production preparation and before the start of the production, information on all the suction nozzles 170 accommodated in the nozzle stocker 186 is again obtained. Is obtained. The possibility of the nozzle arrangement change by the operator is detected based on the presence / absence of an operation normally performed in response to the nozzle arrangement change. For example, if the door provided on the cover that covers the electronic circuit component mounting machine is in an open state, it is determined that the nozzle arrangement may have been changed. The opening and closing of the door is detected by a door opening and closing sensor 332. The door opening / closing sensor 332 is an embodiment of a nozzle arrangement change possibility detection device. An opening / closing detection device for detecting the opening / closing of the detachment preventing member 286 of the nozzle stocker 186 is provided. After the nozzle stocker 186 is attached to the stocker attaching portion 280, the detachment preventing member 286 is opened in addition to holding the suction nozzle 170 by the mounting head 130. If so, the arrangement of the suction nozzle 170 may be changed. If there is a possibility that the nozzle arrangement has been changed to the detachment 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 added. Nozzle accommodation information is obtained.
[0174]
At this time, if the mounting head 130 holds the suction nozzle 170, the suction nozzle 170 returns to the nozzle stocker 186 to receive information. Then, the reader / writer 200 is moved to the information receiving / writing position set for all the nozzle accommodating portions of the nozzle stocker 186 in the same manner as in the production preparation, and performs communication to acquire the nozzle accommodating information. Then, an adsorption tube bending amount / luminous body 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.
[0175]
Thus, 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 the type and number of the suction nozzles 170 accommodated in the nozzle stocker 186 are insufficient. It is determined whether or not all of the suction nozzles 170 of the set type and number are accommodated in the nozzle stocker 186. The type and number of the suction nozzles 170 to be stored in the nozzle stocker 186 are set in advance in the component mounting program according to the type of the printed wiring board 30.
[0176]
By obtaining the suction nozzle information on 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 are known. If these are not insufficient, the determination result in S111 is NO. Then, S112 is executed to check whether or not there is an unusable nozzle that is the suction nozzle 170 that cannot be used for production. This investigation is performed based on the suction nozzle information. In the present embodiment, the usable condition of the suction nozzle 170 is that the bending amount of the suction tube 174 is smaller than the set amount, the luminance of the luminous body is equal to or more than the set value, and the suction error rate (one suction nozzle 170 (The ratio of the total number of suction errors occurred to the total number of suction times) 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. The nozzles are not allowed. In the present embodiment, the unusable nozzle is a defective nozzle.
[0177]
If there is a defective nozzle, the determination result in S112 becomes YES and S113 is executed, and it is determined whether or not there is a substitute nozzle that is a suction nozzle 170 that can be used for production in place of the defective nozzle. As described above, the spare nozzle is accommodated in the nozzle stocker 186, and the suction nozzle 170 of the same type as 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 which is a suction nozzle that can be used for mounting the component 54 similarly to the defective nozzle. According to the type of the component 54, the type of the suction nozzle 170 that can be used for mounting the component 54 is stored, for example, in the part data generator in association with the type of the component 54, and is obtained from the part data generator. A different type of alternative nozzle is searched for based on the component information, the component mounting program, and the nozzle accommodation information, and the determination in S113 is performed. It is sufficient that at least one heterogeneous alternative nozzle is provided. If there is a different type of alternative nozzle, the determination result of S113 becomes YES and S115 is executed, and the serial number and the accommodation position of the alternative nozzle and the serial number and the 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. There may be a faulty nozzle, but there is also a different type of alternative nozzle, so that it is displayed and notified that mounting can be performed.
[0178]
If there is no substitute nozzle, it is determined that the suction nozzles 170 to be used for production are insufficient, the determination result in S113 is NO, S114 is executed, and the shortage of the suction nozzles 170 is notified. The reason for the shortage (there is a defective nozzle), the serial number of the defective nozzle, the storage position in the nozzle stocker 186, the type, and the like are displayed on the display screen 254 and are notified. The storage position is indicated by the number described for the nozzle holding hole 284. This number is associated with a coordinate value that defines the accommodation position, and is holding hole specifying information or identification information that specifies the arrangement of the nozzle holding hole 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 emitting body, and the length of the suction tube 170. The operator sees this and stores the suction nozzle 170 of the same type as the suction nozzle 170 that is insufficient in the nozzle stocker 186. At this time, the defective nozzle is detached from the nozzle stocker 186, and the suction nozzle 170 in the position is accommodated. The suction nozzle 170 is replaced. If there is a vacant nozzle holding hole 284 in the nozzle stocker 186, an alternative suction nozzle 170 may be accommodated therein. The computer may designate a nozzle holding position for holding the suction nozzle 170 in the empty nozzle holding hole 284. Further, the types and storage positions of all the suction nozzles 170 stored in the nozzle stocker 186 may be displayed. Thereby, for example, the operator can compare with the nozzle storage instruction to the nozzle stocker 186 and check whether the wrong suction nozzle 170 is stored. Alternatively, whether or not the wrong suction nozzle 170 is stored may be automatically checked, and if so, the type and storage position of the suction nozzle 170 may be displayed. The same applies to S115, S118, S119, S121, and S122.
[0179]
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 to write the use prohibition information in the tag chip 180 of the defective nozzle, and stores the use prohibition for the defective nozzle in the nozzle accommodation information stored in the mounting control computer 230, and the serial number of the use prohibition nozzle And the fact that the use is prohibited is transmitted to the host computer 240. The suction nozzle 170 on 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. The host computer 240 stores the use prohibition information for the use prohibition nozzle in the suction nozzle information storage unit of the database 262, and stores the serial number of the use prohibition nozzle 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, and the like are similarly performed in S115 and S118 and S119 described later. If there is no defective nozzle, the determination result in S112 is NO and S123 is executed, mounting work start permission data is created and 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 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 worker may determine and instruct the start of the mounting work by himself.
[0180]
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 similarly to S112, it is determined whether there is a defective nozzle. . If there is a defective nozzle, S117 is executed to determine whether or not there is a substitute 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 or not there is a different type of alternative nozzle for the suction nozzle 170 and the defective nozzle for which at least one of the type and the number is insufficient. At least one alternative nozzle is good. If there is an alternative nozzle, the determination result in S117 is YES, and S119 is executed in the same manner as in S115. In S119, the serial number of the substitute nozzle and the storage 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 each defective nozzle. These may be displayed and notified.
[0181]
If there is no alternative nozzle, the result of the determination in S117 is NO, and S118 is executed, for example, notification of nozzle shortage is performed. Here, at least one of the type and number of the suction nozzles 170 is smaller than the set type and number, the presence of a defective nozzle, the serial number of the defective nozzle, the accommodation position, and the like are displayed on the display screen 254. The operator sees the display and replaces the defective nozzle with another suction nozzle 170 or replenishes the suction nozzle 170 that is insufficient. 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 displayed and notified, and a nozzle storage error detection unit is provided. It can also be considered.
[0182]
If at least one of the type and the number of the 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 a substitute nozzle. It is determined whether or not there is a different type of nozzle to substitute for the suction nozzle 170 that is short of at least one of the type and the number. If there is a substitute nozzle, the determination result in S120 becomes YES, and S122 is executed. If there is no alternative nozzle, the result of the determination in S120 is NO, and S121 is executed to notify the nozzle shortage. 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 the number of the suction nozzles 170 accommodated in the nozzle stocker 186 is insufficient. .
[0183]
When a defective nozzle is included in the suction nozzles 170 accommodated in the nozzle stocker 186, it is not indispensable to set a different type of alternative nozzle, and the occurrence of the defective nozzle is reported, and the defective nozzle is replaced. It may be. If at least one of the number and type of suction nozzles 170 in the nozzle stocker 186 is insufficient, it is not indispensable to set a different type of alternative nozzle. Etc. may be performed. When a plurality of suction nozzles 170 required for mounting are accommodated in the nozzle stocker, and the number is only insufficient, the mounting operation may be started without searching for a different type of alternative nozzle.
[0184]
Further, prior to execution of the suction nozzle shortage notification routine, it is checked whether or not an incorrect (not instructed) suction nozzle 170 is housed in the nozzle stocker 186 based on the nozzle housing information and the housing instruction information. If not, the suction nozzle shortage notification routine is executed. If the suction nozzle is not accommodated, the suction nozzle shortage notification routine is not executed, and a wrong accommodation of the suction nozzle 170, a type and a storage position of the suction nozzle 170 are displayed. You may make it notified. In this case, after the operator removes or replaces the wrong suction nozzle 170 from the nozzle stocker 186 or obtains the nozzle accommodation information again by obtaining the tag chip information.
[0185]
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 suction nozzle 170 that is not defective, or replenishes the suction nozzle 170, and after completion, inputs completion. As a result, the reader / writer 200 is again moved to each information receiving / writing position of all the nozzle accommodating sections, and receives the suction nozzle information. As a result, the nozzle accommodation information is acquired, and there is the suction nozzle 170 whose bending or the like of the suction pipe 174 has not been measured. If the measurement is instructed, the measurement is performed. If there is no alternative nozzle, a notification is issued, and replacement and replenishment are performed. These operations are repeatedly executed until the bending amount of the suction pipe 174 is acquired and the type and number of the suction nozzles 170 that are not insufficient for the production are stored in the nozzle stocker 186.
[0186]
As described above, when the suction nozzles 170 are aligned in the nozzle stocker 186 and information is acquired for all the stored suction nozzles 170, the mounting of the component 54 on the printed wiring board 30 is started. The mounting of the component 54 on the printed wiring board 30 has been described above. Here, the acquisition and use of the suction nozzle information will be described in detail.
[0187]
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 sends the component 54 from the feeder 50 or the component tray 110. Is received and mounted on 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 according to a preset rule. For example, the suction nozzle 170 that is used (sucked) less frequently is used first. The suction nozzle 170 having a small number of suction errors may be used first, the suction nozzle 170 having a small number of image processing errors may be used first, and the suction nozzle 170 to be used in combination may be determined. Good. The use order is determined using the suction nozzle information, and the nozzle use order determination unit is also one mode 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 preset different type of alternative nozzle is determined to be the used nozzle in place of the insufficient suction nozzle 170, and the alternative nozzle is set. The nozzle holding routine shown in FIG. 24 is executed for the nozzle. Further, when the nozzle stocker 186 contains a use-prohibited nozzle, the suction nozzle 170 is not used, and the replacement nozzle is used by executing the nozzle holding routine.
[0188]
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 from being used. 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 becomes NO, and the steps from S202 onward 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 performed in detail here. The mounting head 130 is moved to the nozzle accommodation position, and the reader / writer 200 The suction nozzle 170 is moved to the receiving / writing position, lowered to the lower end position and communicates 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 the type 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 nozzle 170 is returned to the nozzle stocker 186 prior to holding the nozzle.
[0189]
If the suction nozzle 170 is not the type to be held, S203 becomes NO and S204 is executed, and a message to that effect is displayed and notified. After the acquisition of the nozzle accommodation information at the start of the production, the arrangement of the suction nozzles 170 may have been changed, and a notification is made and the electronic circuit component mounting machine is stopped.
[0190]
If the suction nozzle 170 to be held is a use-prohibited nozzle, the result of the determination in S201 is YES, and S206 is executed to determine whether there is an alternative nozzle. This determination is made as to whether the nozzle stocker 186 contains a usable suction nozzle of the same type as the use-prohibited nozzle, and whether a suction nozzle 170 that can be used as a substitute for a different type of suction nozzle is stored. It depends on whether or not. Alternative nozzles of the same type are preferentially used, and if there is no alternative nozzle of the same type, alternative nozzles of a different type are used. Therefore, in S206, based on the nozzle accommodation information, first, the same type of alternative nozzle is searched, and if not, a different type of alternative nozzle is searched for and the determination is made. In the case where the suction nozzle which has been used as the substitute nozzle is prohibited from being used as the substitute nozzle, when the determination in S206 is performed, the nozzle itself is already the substitute nozzle and there is no substitute nozzle.
[0191]
Regarding the suction nozzles 170 that have been set as use-prohibited nozzles when stored in the nozzle stocker 186 and the suction nozzles 170 of a type with a shortage in number, different types of alternative nozzles are set in the suction nozzle shortage notification routine, and The determination in S206 is executed. However, as described later, a different kind of alternative nozzle is not set for the suction nozzle 170 which is a use-prohibited nozzle during production, and the same as in S113 of the suction nozzle shortage notification routine is performed. Next, an alternative nozzle is searched for from the suction accommodated in the same nozzle stocker 186. Information on the alternative nozzle, for example, its type and accommodation 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 and S207 is executed, a message to that effect is displayed and notified, and the electronic circuit component mounting machine is stopped. As described later, when a defective nozzle is detected in the nozzle use prohibition routine, an alternative nozzle is searched for. Therefore, the alternative nozzle may be stored, and S206 may be executed based on the information.
[0192]
If there is an alternative nozzle, the determination result in S206 becomes YES, the steps in S208 and subsequent steps are executed, and the suction nozzle 170 is held after checking the type. As described above, the mounting head 130 holds the suction nozzles 170 in accordance with the mounting order (mounting program) and the nozzle accommodation information, and the mounting control computer 230 grasps which suction nozzle 170 is currently used for mounting. I have.
[0193]
When determining the suction nozzle to be used for mounting, first, it is checked whether or not the use of the suction nozzle is prohibited, and the use nozzle may be determined from the available 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 this time, if the suction nozzle of the type instructed to be used and there is no usable suction nozzle, a different type of alternative nozzle is searched for, and if it is used, it is notified, and if not, the electronic circuit component mounting machine is notified. To stop. If a different type alternative nozzle is set in advance, it is used. Then, when holding the suction nozzle determined to be used, a nozzle type confirmation routine shown in FIG. 12 is executed.
[0194]
When the component 54 is mounted on the printed wiring board 30, the number of suctions, the number of suction errors, 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 accommodation position. Of these, a part for storing the number of times of suction, the number of suction errors, and the number of image processing errors is constituted by a counter. Each time is counted and updated. The number of suctions, the number of mistakes, and the number of errors stored in the tag chip 180 are the total numbers (accumulated) of suctions, errors, and errors that have been performed in the past for the suction nozzle 170 provided with the tag chip 180, respectively. The initial value of the counter is the number of times of suction recorded on the tag chip 180 and the like, and is set to the latest value. Separately from the storage of the suction nozzle information, a counter is provided to count the number of suction, the number of errors, 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 number may be added to the number stored in the nozzle accommodation information memory and stored, and the number may be added to the number recorded in the tag chip 180 and 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 removed from the nozzle stocker 186.
[0195]
In the present embodiment, the suction error is that the component 54 could not be suctioned even though the suction nozzle 170 performed the suction operation, and the component 54 could be suctioned, but the component was sucked in a standing posture. The 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 regular dimension without any error or deviation is equal to or larger than the set value, it is determined that the type is wrong or the component 54 has been sucked in a standing posture.
[0196]
In the present embodiment, the image processing error is determined by determining whether the component 54 has a lead, the rotational position error and the translational position error cannot be acquired within the set time, If the difference from the regular interval is equal to or larger than the set value, or if the lead is bent, an image processing error is determined.
[0197]
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 to the tag chip 180. The latest information is recorded on the tag chip 180.
[0198]
The mounting control computer 230 also stores production information. The production information includes, for example, as shown in FIG. 31, 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 has 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 on the suction nozzle 170 includes a serial number, the number of suctions, the number of suction errors, the data of suction errors, the number of image processing errors, and error data. Each of these times is the total number (cumulative) at that time, and is obtained from the suction nozzle information stored in the nozzle accommodation information memory. Each of the suction error data and the error data is stored as a code. The code and the data representing the content of the mistake 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 mistake or error can be known from the code. This production information is also a production information history.
[0199]
The suction nozzle 170 is replaced in accordance with the type of the component 54 to be mounted, and is also replaced, for example, when it is estimated that the suction nozzle 170 is an unusable defective nozzle due to frequent errors. This nozzle replacement is performed according to a nozzle use prohibition routine shown in FIG. This routine is executed by the mounting control computer 230 during production, for example, every time one component 54 is mounted.
[0200]
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 to the total number of suctions) after the start of a series of mounting operations to the same type of printed wiring board 30 is equal to or higher than the set rate, and if mistakes are occurring frequently, use is prohibited. This is a possible defective nozzle, and the result of the determination in S161 is YES, and S162 is executed to determine whether or not replacement is possible. In the present embodiment, a spare nozzle is housed in the nozzle stocker 186, and a plurality of suction nozzles 170 of the same type are housed. A suction nozzle 170 of the same type, whose use is not prohibited, is used. If present, it is first used for mounting. If no similar suction nozzle 170 is available, an alternative nozzle is searched for a different suction nozzle 170. For suction nozzles of the same type as suction nozzles whose use has been prohibited, different types of alternative nozzles are set when the nozzles are stored in the nozzle stocker 186, and the different types of alternative nozzles are used if possible. If any of the suction nozzles 170 can be replaced with a defective nozzle by any of the methods, the determination result of S162 becomes YES, and S163 is executed, and the suction nozzle 170 is replaced. The defective nozzle currently held by the mounting head 130 is returned to the nozzle stocker 186, and the suction nozzle used instead of the defective nozzle is held. At the time of this return, it is confirmed that the nozzle holding hole 284 is empty, and at the time of holding, the suction nozzle type is confirmed. Then, step S164 is executed, and the use of the suction nozzle 170 is prohibited. This use prohibition is performed in the same manner as in the suction nozzle shortage notification routine S114 shown in FIG. Here, since the mounting operation is being performed, the use prohibition data is written to the tag chip 180 of the defective nozzle returned to the nozzle stocker 186, and the data updated during use is also written. It is also stored in the mounting control computer 230 and the like.
[0201]
By prohibiting the use of the defective nozzle before or during the production as described above, for example, the use prohibition nozzle can be used to mount the component on another type of printed wiring board 30 without eliminating the cause of the prohibition. Therefore, when the suction nozzle shortage notification routine is executed, it is determined that there is a use-prohibited nozzle even if it is stored in the nozzle stocker 186, and it is avoided that the nozzle is used for mounting. Also, 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 accommodate the use prohibition nozzles in the nozzle stocker 186.
[0202]
If there is no suction nozzle 170 that can be replaced even if a defective nozzle occurs, the determination result in S162 is NO, S165 is executed, and a message to that effect is displayed and notified. Further, the electronic circuit component mounting machine is stopped.
[0203]
Even if suction errors occur frequently as described above and the suction nozzle is set as a use prohibition nozzle, or if the use prohibition nozzle is resolved because the luminance of the illuminant is smaller than the set value, use of the suction nozzle will be continued if the cause of use prohibition is resolved. The prohibition is released. For example, if the cause of prohibition of use of the suction nozzle 170 is eliminated by performing maintenance such as cleaning of the luminous body and cleaning of the suction tube 174, the operator inputs the fact to the host computer 240 and the prohibition of use is released. To do. After the maintenance, it is desirable that the inspection device inspects whether the suction nozzle 170 can normally mount the component 54 or not.
[0204]
If the execution of the use prohibition release is input, the use prohibition release routine shown in FIG. 26 is executed, and it is determined in S181 whether or not the serial number of the suction nozzle 170 has been input. If the serial number of the suction nozzle 170 for canceling the use prohibition is input, the determination result in S181 becomes YES, and S182 is executed, and the use prohibition is canceled. The use prohibition information stored in the use prohibition information storage unit of the host computer 240, that is, the information about the suction nozzle 170 having the input serial number is deleted. The serial number and the like are 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. Note that the number of suction errors at the time of use prohibition release input, the use prohibition release date, and the like may be stored as a kind of suction nozzle information.
[0205]
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 abrasion of the suction end face or the like, the vertical stroke of the mounting head 130 when the component 54 is suctioned and mounted is corrected. For example, as described in Japanese Patent Application Laid-Open No. 2001-345599, an image pickup device takes an image of the suction tube from a direction perpendicular to its axis, acquires the position of the suction end face, and obtains the actual length of the suction tube 174. Is obtained, and is compared with the regular length recorded in the suction nozzle information to calculate the correction amount. The imaging device and the image processing computer constitute a position error acquisition device or a correction data acquisition device. The correction amount is measured, for example, when the suction nozzle 170 is not used for mounting and is not stored 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. I have. The change information may be recorded on the tag chip 180 of the suction nozzle 170.
[0206]
When the suction nozzle 170 takes out the component 54 from the feeder 50 and mounts the component 54 on the printed wiring board 30, a lifting 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 in S192, the vertical stroke is corrected based on the correction amount. Note that a correction data acquisition device may be provided in the electronic circuit component mounting machine so that the correction amount is acquired. If the correction amount is not stored in the host computer 240, or if the storage amount is old and the setting period has elapsed since the acquisition, or if the number of times of mounting exceeds the set number, the correction amount is Is not preferably used, and the vertical stroke is corrected by acquiring the correction amount in the electronic circuit component mounting machine. The acquired correction amount is sent to the host computer 240 together with the serial number of the suction nozzle 170 and the date and time of acquisition, and stored therein.
[0207]
Each time the mounting of the component 54 on one printed wiring board 30 is completed, the production information and the suction nozzle information are transmitted to the host computer 240, and the production information is stored in the database 262. The information 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 change information such as the number of times of suction is updated in the information on the suction nozzle 170, 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 for the suction nozzle 170.
[0208]
During production, the host computer 240 provides maintenance guidance and notification of a possible failure nozzle based on the suction nozzle information.
The maintenance guidance is performed according to a maintenance guidance routine shown in FIG. This routine is executed for all the suction nozzles 170 currently stored in the nozzle stocker 186 and used for production. When the mounting of the component 54 on one printed wiring board 30 is completed, suction nozzle information is newly obtained. It is executed every time. In S131, it is determined whether or not the number of times of suction is equal to or more than the set number of times. 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 storage number storage unit for maintenance guidance determination, and for each of the suction nozzles 170, the number of suctions of the suction nozzles 170 at the time when the latest maintenance is executed is set to the serial number of the suction nozzles 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 is equal to or greater than a set number, and the number of suctions is smaller than the set number. , The determination result in S131 is NO, and the execution of the routine ends.
[0209]
If the number of suctions is equal to or greater than the set number, the determination result in S131 is YES, and S132 is executed, and maintenance guidance is output to the mounting control computer 230. In the present embodiment, the maintenance guide condition is that the number of suctions after the latest maintenance is equal to or more than the set number of times is a maintenance guide condition. A number and a maintenance execution instruction are output. When the maintenance guide is supplied, the mounting control computer 230 displays it on the display screen 254 to notify the operator. In accordance with the maintenance guide, the operator performs maintenance such as cleaning of the suction pipe 174 and the background forming plate 176 after the end of the production or after the completion of mounting the components on one printed wiring board 30.
[0210]
When the maintenance is completed, the operator inputs the serial number of the suction nozzle 170 that has performed the maintenance and the end of the maintenance to the mounting control computer 230, and the mounting control computer 230 sends the information and the maintenance execution date and time to the host computer 240. . The operator may directly input the information 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 is selected from the maintenance guide determination suction frequency storage unit of the maintenance execution information storage unit. Is updated, and the number of suctions obtained from the suction nozzle information stored in the database 262 at the time when the maintenance execution information is obtained is stored as the number of suctions when the maintenance is performed. As described above, since the host computer 240 stores the 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, the maintenance guide is used using the information. Can be put out.
[0211]
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 highly likely to be a failure nozzle, and the failure possibility nozzle notification routine is performed every time the 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 control computer 230 is performing the mounting operation. In S141 of this routine, it is determined whether or not the suction error rate of the suction nozzle 170 currently used for mounting the component 54 is equal to or higher than the set rate. The suction error rate is a ratio of the total number of suction errors generated in the suction nozzle 170 to the total number of suction times, and the set rate for detecting an unusable defective nozzle in S161 of the nozzle use prohibition routine is as follows. The ratio is set to be larger than the setting ratio of S141.
[0212]
If the suction error rate is equal to or higher than the set rate, the result of the determination in S141 is YES, and S142 is executed to notify the occurrence of a defective nozzle. The serial number of the suction nozzle 170 whose suction error rate is equal to or higher than the set rate and information indicating the possibility of a defective nozzle are sent to the mounting control computer 230. The mounting control computer 230 displays the information on the display screen 254. Display and notify operator. Based on the display, the worker recognizes that there is a suction nozzle 170 whose use may be prohibited in the near future, and prepares the suction nozzle 170 for replacement, or notifies the suction nozzle 170 If the nozzle 170 is a suction nozzle 170 that is frequently notified as a possible failure nozzle even after performing maintenance, appropriate measures such as performing particularly careful maintenance and inspection of the suction nozzle 170 after the end of production, etc. be able to. The host computer 240 also stores the serial number of the defective nozzle and the information of the defective nozzle.
[0213]
It should be noted that the information on the possible failure nozzle is also supplied to another mounting machine and is notified to the operator. The serial number of the defective nozzle and information indicating that the nozzle may be defective are displayed on the display screen 254. On the basis of this display, the operator can appropriately deal with the possibility nozzle in other mounting machines. The defective possibility nozzle is not so bad as to prohibit its use, so it is used for mounting, but other mounting machines are notified of the possibility of defective nozzle from the beginning of mounting, and the worker We can cope from time.
[0214]
If the suction error rate is smaller than the set rate, the determination result of S141 is NO, and the execution of the routine ends. Although the illustration and description of the flowchart are omitted, the cancellation of the failure possibility nozzle is performed in the same manner as, for example, the cancellation of the use prohibition of the suction nozzle 170. When the operator performs maintenance or the like based on the notification of the possible failure nozzle and the cause of the failure is released, the fact and the serial number of the possible failure nozzle are input to the host computer 240, and the suction nozzle 170 The failure probability information regarding the information is deleted. Once the suction error rate becomes equal to or higher than the set rate, no suction error occurs, and the suction error rate may become smaller than the set rate. Therefore, when the determination result of S141 is NO, the failure possibility information may be erased.
[0215]
The failure possibility nozzle detection condition includes, in addition to 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 number of suction errors is equal to or higher than the set number, The number of errors may be equal to or greater than a set number. These may be combined. The same applies to the use prohibition nozzle detection condition.
[0216]
In the host computer 240, production history information is created based on the production information and the 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 during which information for creating production history information should be collected using the input device 260, and instructs a list display of all the suction nozzles 170 used for mounting during 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 modes. For example, the setting period is set from 8:00 am to 5:00 pm on a certain month and a certain day. The production history information creation condition is set by the operator.
[0219]
Although there are various kinds of information on the suction nozzle 170, usually, as shown in FIG. 33, production history information is created including basic items which are preset items. The number of suctions may be the number of suctions in the set period (the number of suctions performed from the start to the end of the set period), and is the total number of suctions at the end of the set period and the total number of suctions before the set period. And the sum of the number of suction operations within the set period. In addition, the suction error and the image processing error are displayed as occurrence rates (the ratio of the number of suction errors to the number of suctions and the ratio of the number of image processing errors to the number of suctions). The occurrence rate may be a ratio of the number of suction errors and the number of image processing errors occurring in the setting period to the number of suction operations in the setting period, and is obtained including the total number of suction operations, the number of errors and the number of errors before the setting period. The occurrence rate may be used. Whether the number of times of suction and the occurrence rate of suction errors and the like 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 in accordance with the settings of the operator, for example, designation items designated by the operator, such as the wiring board ID of the printed wiring board 30 on which the suction nozzle 170 has mounted the component 54 and the type of the component 54. , The production history information may be created and displayed.
[0218]
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, and the like 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 that is likely to cause a problem can be quickly identified.
[0219]
In addition, the operator inputs the wiring board ID of the printed wiring board 30 in order to create the production history information, and includes all the suction nozzles 170 used for mounting the component 54 on the printed wiring board 30. If the instruction is given as the production history information creation condition, the production history information including the information on 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 to mount the component 54 on the printed wiring board 30, the number of suction times, the suction error rate, and the image processing error rate are the values at the time of the last use. Is displayed.
[0220]
Since the serial numbers are assigned to all the suction nozzles 170 as described above, the suction nozzles 170 can be individually identified, regardless of which type of the printed wiring board 30 is used to mount the component 54. At the same time, the current status can be acquired by totalizing the usage status. In addition, since the amount of information that can be recorded on the tag chip 180 is large, a large amount of information can be recorded both in terms of type and amount, and the information can be updated. It can be used in various modes such as checking the type and determining whether or not it can be used. Furthermore, since the production information is created by associating the wiring board ID with the serial number of the suction nozzle 170, the production history information including the information on the suction nozzle 170 can be created based on the wiring board ID. For example, when the mounting of the component 54 on the printed wiring board 30 is not performed normally and a defective printed circuit board is manufactured, the cause including the suction nozzle 170 can be analyzed. 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 a suction error has occurred is included. Production history information can be created.
[0221]
The inspection result by the mounting inspection machine 266 is supplied to the host computer 240. If the mounting is not performed normally, the mounting sequence number for mounting the component 54 in which the mounting abnormality has occurred is displayed and displayed on the display screen 264, 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 be the cause of the mounting accuracy failure by looking at the display.
[0222]
The mounting mode in which the plurality of suction nozzles 170 are used to mount the component 54 on one type of printed wiring board 30 and the suction nozzles 170 are replaced during production has been described. There is also a printed wiring board 30 in which only one suction nozzle 170 is used to mount the component 54 to the device, 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 finished and the setup is changed, the information acquired during the production is written to 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 of the suction nozzle 170, the information is returned after the abnormal suction nozzle 170 is returned to the nozzle stocker 186. Written.

In addition, a portion of the feeder detection device 246 and the control device 24 that performs S5 constitutes an exchange start detection unit. Further, a portion of the control device 24 for confirming the type of the nozzle stocker 186 based on the information recorded on the tag chip 320 of the nozzle stocker 186 constitutes a nozzle stocker type confirmation unit which is a type of information use unit.
Also, the part of the control device 24 that executes S92 and S94 constitutes a change information acquisition unit, and the part that executes S85 notifies the operator that change information has not yet been acquired by the change information acquisition unit. And a portion that causes the nozzle holder 168 to return the suction nozzle 170 to the nozzle stocker 186 when information is recorded on the tag chip 180 by the reader / writer 200, such as a portion that performs steps S93 and S95. , S114, S118, and S121 constitute a missing nozzle notification unit.

In the above-described embodiment, the connection of the taping component 58, the replacement of the feeder 50, and the next designation are performed in the feeder-type component supply device 18, but any one of these components can be used. Alternatively, only two may be performed. In the tray type component supply device 20, only one of the replacement of the component tray 100 and the next designation may be performed.
[0236]
Further, the type of the component 54 accommodated in the component supply devices 18 and 20 is confirmed when the component is mounted on the feeder support base 48 of the feeder 50 and the component tray 110 and the component tray storage box 114. The confirmation work by the operator at the time may be omitted. In this case, for example, in the case of the feeder-type component supply device 18, 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, the tag chips provided on the feeders 50 are provided. 98 is read by the reader / writer 200. At this time, the reader / writer 200 is moved to the tag chip 98 to be read and is moved to the lower end position, and the tag chip 98 may perform wireless communication with the tag chip 98 of the adjacent feeder 50. Down to a distance where there is no The feeder information is obtained by receiving the information recorded on the tag chip 98, whereby the type of the component 54 can be confirmed, and the feeder 50 holding the type 54 of the type different from the set type is mounted. Notification, and processing such as exchange is performed. The reception of the information recorded on the tag chip 98 may be performed when the electronic circuit component is first taken out of each of the plurality of feeders 50 after mounting.
[0237]
When the supply of electronic circuit components is performed by connecting the taping electronic circuit components, the information of the tag chip provided on the new taping electronic circuit component is not read at the time of connection work, but the reader is used to detect the tag chip at the time of supplying the electronic circuit component. When communication is performed with the writer / writer, the type of the connected taping electronic circuit component may be confirmed based on the information read thereby. At this time, if the wrong type of taping electronic circuit component is connected, for example, the electronic circuit component mounting machine is stopped.
[0238]
Further, when a tag chip is provided on a taping electronic circuit component, it may be provided on a carrier tape. For example, a tag chip is attached to a portion between the perforations. The cover is provided with an opening from which teeth of a 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, the information is read in a state where the tag chip provided on the cover tape is located on the upstream side of the cover.
[0239]
The tag chip may be provided in a unit or a device constituting the electronic circuit assembly system. For example, a multi-feeder unit configured so that a plurality of feeders together with the feeder support stand are attached to and detached from the main body of the mounting machine, and a plurality of component trays together with the support member are mounted together. A multi-tray unit configured to be attached to and detached from the main body of the machine and configured to be replaced may be provided with a tag chip to record information and used for, for example, replenishment of parts.
[0240]
Further, information may be written to the tag chip. For example, before removing a feeder from a feeder support base in a feeder-type component supply device during setup change, the remaining number of electronic circuit components held by the feeder is written and recorded in a tag chip of each feeder. Therefore, when the feeder is used for supplying electronic circuit components as it is next, the information recorded on the tag chip is received by the receiving device, and the holding of the electronic circuit components held by the feeder at the start of a series of mounting work is performed. The number is the initial accommodation number.
[0241]
Further, the reception of the information recorded on the tag chip may be performed with the reader / writer stopped.
[0242]
If one feeder supplies electronic circuit components to a single circuit board at a plurality of different times, the feeder replacement start period is calculated in consideration of this.
[0243]
Further, the acquisition of the component shortage feeder and the acquisition of the component supply time may be performed during the component mounting operation.
[0244]
Further, the tag chip provided on the component holder may be used for accommodating the component holder in the holder accommodating device, for example, in addition to the replacement of the component holder. When the storage position of the component holder in the holder storage position is set in advance, whether or not the predetermined component holder is stored in the predetermined storage position is recorded in a tag chip provided in the component holder. It checks using the information provided. In this case, a component holder accommodation support unit, which is a type of a component holder-related work assistance unit, is provided.
[0245]
Furthermore, although the tag elements are provided in all the components of the electronic circuit assembly system, such as the suction nozzle 170, a two-dimensional code may be provided instead of the tag chips to configure the information recording unit. The two-dimensional code is a read-only information recording unit, for example, in which identification information and invariable information are recorded and read by an information reading device. The information reading device includes, for example, an imaging device as a recognition device. The imaging device is configured 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 is used. Is capable of reading information by the imaging device, and has a light reflectance different from that of the nozzle holding hole, and is formed in a color in which the suction nozzle exists even when the two-dimensional code is irradiated with light. Is desirable. When the two-dimensional code is provided, if the information recording amount is insufficient, for example, the two-dimensional code is stored in the computer in association with the individual identification information and the type related information of the member provided with the two-dimensional code, and is stored in the two-dimensional code. Based on the reading of the individual identification information or the like, the information associated therewith may be read and used. Other than the two-dimensional code, the same applies to an information recording unit whose recording amount is insufficient.
[0246]
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 is changed and the setup is changed, the nozzle stocker 186 is stored. Although the 186 is replaced, 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 may be set for each printed wiring board in the nozzle stocker, and may be separately stored for each type of printed wiring board. It may be.
[0247]
Further, the detection of the presence or absence of the suction nozzle in the nozzle stocker is performed using a nozzle sensor and is performed by a device dedicated to detection, but the detection is performed based on whether or not information is obtained from the information recording unit. Is also good. If the information acquisition device is moved to the preset information acquisition position and performs the acquisition operation, but the information is not acquired, it is determined that the suction nozzle is not housed. In this case, the information acquisition device doubles as the nozzle detection device.
[0248]
Further, the positioning device or the component holder phase determining device that determines the phase of the suction nozzle when 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, and a mark that defines a nozzle holding hole of the nozzle stocker and is not covered by the separation preventing member at least in a state where the separation preventing member is located at the release position. The suction nozzles are accommodated in the nozzle stocker so that their positions coincide around the axis of the suction nozzle. When an electronic tag or a two-dimensional code is provided on the background forming member, the electronic tag or the two-dimensional code may function as a nozzle-side mark, or a dedicated mark may be provided separately from them. Further, a stocker side mark may be provided in the nozzle holding hole.
[0249]
Further, the information recorded in the information recording section of the suction nozzle is obtained in a state where the suction nozzle is not held by the nozzle holder and is returned to the nozzle stocker. May be acquired in a state of being held. In particular, when the information recording unit is configured by an electronic tag, the information acquisition device can acquire information even when it is away from the electronic tag, so that the information acquisition device has a high degree of freedom in acquisition and acquires the information while holding it in the nozzle holder. Sometimes it is easy.
[0250]
In addition, 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 luminous body, the bending amount of the suction tube may be determined when measuring the luminous body luminance, It may be performed when a preset condition is satisfied, may be performed during production, or may be performed at times other than during production. For example, it may be performed every time the mounting of components on one printed wiring board is completed during production, or may be performed at the end of production. For the suction nozzle whose use is prohibited, the fact that the nozzle is a use prohibition nozzle is recorded in the information recording unit. When the use prohibition release condition is satisfied, the use prohibition information in the information recording unit is erased and the usable nozzle is set. The use prohibition judgment result by at least two of the use prohibition judging elements for judging the use prohibition of the suction nozzle, such as the amount of bending of the suction tube, the luminance of the luminous body, the occurrence rate of the suction error, the occurrence rate of the image processing error, etc. In some cases, the use of the suction nozzle may be prohibited.
[0251]
Furthermore, although the set time for judging that the amount of bending of the suction tube is not measured and the luminance of the luminous body is not measured were set to be the same, they were made different, so that they were measured at different times. Is also good.
[0252]
The production history information can be created in various modes according to the history creation conditions or the settings of the history creation elements. For example, the production history information is created by combining the component information, for example, the serial number of the suction nozzle and the board ID. Alternatively, it may be created by combining the component information and the type of the circuit board, or may be created by combining a plurality of types of component information. The combination is set in advance, and may be selected by a person from the combination information, or may be arbitrarily set by the person.
[0253]
Furthermore, the production history information may be instructed to be created in the mounting control computer 230, created in the host computer 240 based on the instruction, transmitted to the mounting control computer 230, and displayed on the display screen 254.
[0254]
Further, the created production history information may be printed on a print medium by a printer. A printer is a type of output device and outputs by printing. Further, the created production history information may be stored and stored in a production history information storage unit of a storage means such as a RAM or a database of the host computer.
[0255]
Further, the information transmission method between the electronic tag and the information receiving device or the information receiving / writing device depends on the shape and size of the member provided with the electronic tag, the distance between the electronic tag and other members provided with the peripheral electronic tag. If the communication target is specified in accordance with the information acquisition conditions, etc., a transmission method in which the communication distance is relatively long may be adopted.
[0256]
Further, 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 for housing a component tray. In this information recording unit, information on the component tray or the components contained in the component tray is recorded in the same manner as in the case where the information recording unit is provided on the component tray. Information about the component tray housing member, for example, shape, dimensions, etc., may be recorded.
[0257]
Further, the information recording unit such as a tag chip provided on the suction nozzle may be provided at a position covered by the detachment prevention member when the detachment prevention member is located at the detachment prevention position. When acquiring the information recorded in the information recording unit, the detachment prevention member is moved to the open position and retracted from the information recording unit.
[0258]
Further, in the above embodiment, the suction error rate is used in the nozzle use prohibition routine to determine whether or not the suction nozzle is unusable and in the failure possibility nozzle notification routine to determine whether or not the suction nozzle is a defective nozzle. The suction error rate is calculated as the ratio of the number of suction errors to the total number of suction operations of the suction nozzles, but is calculated as the ratio of the number of suction errors to the suction operation of the suction nozzles during the set production operation. Although not yet disclosed, the error rate at the present time (at the time of the determination) is obtained and used for the determination by the method described in the specification of Japanese Patent Application No. 2002-136943 of the present applicant. You may. Alternatively, the determination may be made based on whether or not the number of suction errors is equal to or greater than a set number. When detecting a defective nozzle in the suction nozzle shortage notification routine, the detection may be made based on whether or not the number of suction errors is equal to or greater than a set number. The fact that the number or occurrence rate of image processing errors is equal to or greater than a set value may be used as the suction nozzle use prohibition condition.
[0259]
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 storage device that stores components that are removed from the component supply device by the mounting head but are not attached to the circuit board, the component storage device is also a constituent element, and may be a two-dimensional code or If an information recording unit such as an electronic tag is provided, information recorded on the information recording unit can be used in various modes.
[0260]
The component taken out by the mounting head is not suitable for mounting in the position, posture, etc., the component holding position error of the component holder is larger than the set value, or the lead has a large bending. When the discarded component is detected by a detecting device or the like and is discarded as a discarded component, the component is not mounted on the circuit board but is stored in the component storage device. Therefore, as a component storage device, for example, although not disclosed yet, as described in the specification of Japanese Patent Application No. 2003-354 of the present applicant, the internal space of the storage container having a container shape has a plurality of spaces. There have been proposed ones provided with a plurality of storage chambers separated by a partition member, and those provided with a plurality of storage chambers in which a holder holds a plurality of small containers. In the plurality of storage chambers, for example, components to be discarded are stored separately for each type. The storage chamber may be fixedly provided. By changing the position of the partition member or changing the combination of a plurality of types of small containers having different capacities, the capacity (volume) of the storage chamber of the component storage device is changed. ), The number of components may be different, and a component storage device having a storage chamber according to the type and number of components to be mounted may be provided.
[0261]
When changing or setting the configuration of the accommodation room, for example, an operator arranges the partition member or the small container in the accommodation container or the holder 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 capable of individually identifying the component storage devices is recorded. The operator acquires the individual identification information by the information acquisition device when arranging the partition member and the storage container and stores it in the host computer, and the host computer will obtain the individual identification information by the arrangement of the partition member and the small container. The stored capacity and arrangement of the accommodation room are stored in the component accommodation device information memory in association with each other.
[0262]
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 the printed wiring board, instructs the individual identification information based on the individual identification information, and provides the operator with the electronic circuit component. Attach to the mounting machine. After installation, check the storage room of the component storage device. For example, a mark is provided on a partition member, an image is taken by an image pickup device as a mark acquisition device, and the arrangement of the partition member is acquired. Obtain capacity, layout, number, etc. The position of the mark is obtained, for example, from the position of the partition member mounting portion formed at a preset pitch in the container for mounting the partition member, and the position of the component storage device in the electronic circuit component mounting machine. The acquired capacity of the accommodation room and the like are compared with the planned capacity and arrangement of the accommodation room obtained from the individual identification information of the component accommodation device, and it is confirmed whether or not the set accommodation room is provided. If the set accommodation room is not obtained, for example, a notification is issued, and the operator is caused to change the accommodation room or to replace the component accommodation device itself. The same applies to the case where the accommodation chamber is provided by the arrangement of the small containers. In the case of a small container, the small container is provided with an information recording unit indicating its type (identified by shape and size), and the small container held by the holder is obtained by acquiring the information recorded in the information recording unit. It is also possible to obtain the type, number, etc. of the storage space and obtain the capacity, arrangement, and the like of the accommodation room.
[0263]
If the component storage device set in this way is mounted on the electronic circuit component mounting machine, when disposing of the component that has not been mounted, it is mounted according to the type of the storage component set for each of the plurality of storage rooms and the arrangement of the storage rooms. The head is moved to a storage chamber where the components are to be discarded and stored. At this time, the number of components accommodated in each of the plurality of types of accommodation rooms is counted and stored in the mounting control computer in association with the position of the accommodation room and the accommodation components.
[0264]
After the end of the series of component mounting on the circuit board, the component storage device is removed from the electronic circuit component mounting machine and the stored components are processed. Of the stored discarded parts, reusable parts are made to be reused, and non-reusable 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 arrangement of the storage room, the number and type of the stored components, from the mounting control computer to the host computer. Sent to host computer. Usually, the work of disposing of discarded components is 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 the information are displayed on the display device. The worker is notified of the work, and the worker can easily perform the work. This is because the arrangement of the accommodation room and the component accommodation situation 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.
[0265]
When the information recording unit is a two-dimensional code or a read-only electronic tag, it is not possible to record change information such as the number of accommodated components, but by recording the individual identification information of the component accommodation device, It can be used for confirming the configuration and displaying information at the time of processing of the housed parts. For example, an operator inputs individual identification information at the time of processing a stored component, and the host computer causes the display device to display component storage-related information based on the individual identification information.
[0266]
In the case where the configuration of the component storage device is invariable and the number, capacity, arrangement, and the like of the storage rooms are fixed, the information recording unit stores the individual identification information of the component storage device and the capacity, number, layout, and the like of the storage rooms.
