Note that the predetermined position is set at a central portion of the backup plate 31 in the board width direction, that is, a position corresponding to the through hole portion 31ha. The storage table 41b is also arranged to be movable up and down at a predetermined position. Note that the predetermined position is set at the center of the backup plate 31 in the board width direction, that is, at a position corresponding to the through hole portion 31hb.

Further, the

movable conveyor rails

22a and 21b are movably arranged above the storage tables 41a and 41b located at positions (predetermined positions) corresponding to the through-hole portions 31ha and 31hb. At this time, the storage tables 41a and 41b are preferably in the lowered position, but the moving

movable conveyor rails

(Operation of component mounter)
Next, the operation of the component mounter 10 of this embodiment described above will be explained along the flowchart shown in FIG. 8. In step S102, the control device 90 reads (obtains) a production program (job) from the management computer. The production program is a program for producing a mounted board in which the component P is mounted on the board S, and includes information on the size of the board S, board information on the offset of the position where the board is stopped during mounting (board stop position), and support information. The arrangement position of the backup pin 35a (hereinafter sometimes referred to as a support location; these position coordinates), the range of the backup plate 31, the component mounting position (coordinates) on the back surface of the board S, and/or the solder printing location ( Contains information on the back side of the board related to the placement position (coordinates) of the solder printing position. Note that the size information of the substrate S includes the size in the transport direction (X-axis direction) and the size in the substrate width direction (Y-axis direction). The offset of the board stop position is an offset with respect to the reference point of the component mounter 10. In addition, the component mounting position on the back side of the board S is the mounting position of already mounted components (pre-installed components), and the placement position of the solder printing location is the position where solder has already been printed (solder is not printed). (including certain printable locations), and includes, for example, the layout positions of the lands of the pattern.

The control device 90 installs the supporting backup pins 35a on the backup plate 31 before starting production of the mounting board. In step S104, the control device 90 executes a process of installing (moving) the supporting backup pin 35a in the first lane 20a (first lane pin installation (moving) process), and in step S106, the process of installing (moving) the support backup pin 35a in the second lane 20b is performed. Then, a process of installing (moving) the support backup pin 35a (second lane pin installation (movement) process) is performed.

(1st lane pin installation (movement) process)
The first lane pin installation (movement) process will be described in detail along the flowchart shown in FIG. In the first lane pin installation (movement) process, first, the control device 90 drives the head moving device 70 to move the head 50 above the nozzle stocker 81, and replaces the nozzle attached to the holder 52 with the picker nozzle 60 ( Step S202). Subsequently, the control device 90 acquires width information of the substrate S to be transported on the first lane 20a and layout information of the supporting backup pins 35a of the first lane 20a from the management computer (step S204).

Then, when moving the supporting backup pin 35a to the placement target conveyor, the control device 90 executes a pin movement preparation process of moving one of the movable conveyor rail and the storage table relative to the other (control unit). . That is, before moving the support backup pin 35a to the placement target conveyor, the control device 90 moves one of the movable conveyor rail and the storage table relative to the other.

Specifically, in step S206, the control device 90 drives the accommodating table lifting device 43 to lower the first accommodating table 41a and the second accommodating table 41b. Further, in step S208, the control device 90 drives the rail moving device 28 to move the subordinate rail 22a of the first lane 20a, which is a movable conveyor rail, and the reference rail 21b of the second lane 20b to the second lane 20b side. (See Figure 11B). At this time, the movement destinations of the subordinate rail 22a and the reference rail 21b are preferably positions other than directly above the first storage stand 41a and the second storage stand 41b (through-hole portions 31ha, 31hb), and the first storage stand 41a and the A position closer to the second lane 20b than the second storage stand 41b (through-hole portions 31ha, 31hb) is preferable.

In this way, before arranging the support backup pin 35a on the first lane 20a, which is the lane to be arranged and which is the lane in which the backup pin 35 is arranged, the control device 90 moves the supporting back-up pin 35a to the subordinate rail, which is a movable conveyor rail. 22a and the reference rail 21b, and one of the first storage stand 41a and the second storage stand 41b is moved relative to the other (relative movement step). As a result, the control device 90 drives the head 50 to move the backup pins 35 placed on the first accommodating table 41a and the second accommodating table 41b to a predetermined support location of the backup plate 31 (first lane 20a). When moving and placing the backup pin in the upper backup pin placement range 31a1 (see Figure 11A), there is no need to overcome obstacles such as conveyor rails. All the backup pins 35 on the first storage stand 41a and the second storage stand 41b can be used as support backup pins 35a.

The backup pin arrangement range 31a1 is a range in which the supporting backup pins 35a can be arranged, and is a range set to be slightly narrower than the external dimensions of the substrate S, taking into consideration the movable range of the head 50, etc. is preferred. Also, on the second lane 20b, a backup pin placement possible range 31a2 (see FIG. 11A) is set, similar to the first lane 20a.

Next, in step S210, the control device 90 drives the accommodating table lifting device 43 to raise the accommodating table 41a of the first backup pin stocker 40a and the accommodating table 41b of the second backup pin stocker 40b. Further, in step S212, the control device 90 images the entire range of the backup plate 31 (including the through holes 31ha and 31hb) using the mark camera 83. Note that if the storage tables 41a and 41b do not overlap the backup plate 31 in the vertical direction, the imaging range is the sum of the entire range of the backup plate 31 and the total range of the storage tables 41a and 41b. That is, both the backup plate 31 and the accommodating tables 41a and 41b are within the imageable range.

Subsequently, after the above-described relative movement, the control device 90 moves the backup pin 35 (supporting backup pin 35a) to the placement target lane (backup member movement (processing) step). That is, in step S214, the control device 90 processes the captured image to recognize the positions of the backup pins 35 placed on the storage tables 41a and 41b and the backup pins 35 placed on the backup plate 31, and then processes the captured images in step S204. The supporting backup pin 35a is moved according to the layout information received in (see FIG. 11C). Specifically, the control device 90 drives the head moving device 70 to move the picker nozzle 60 directly above the backup pin 35 to be moved. Next, the control device 90 drives the head 50 to fit the engaging portion 39 (protruding portion) into the hook recess 65 of the picker nozzle 60, thereby causing the picker nozzle 60 to pick up the backup pin 35. Then, the control device 90 drives the head moving device 70 to move and place the collected support backup pin 35a to a predetermined support location.

Incidentally, the backup pin 35 is manually inserted and placed in the placement location of the storage table 41, which is also the initial placement location, by the operator. Further, the placement at the initial loading location may not be done manually but may be automatically loaded using the head 50. Furthermore, the initial loading location may be a location other than the storage table 41, and even if it is on the backup plate 31 or outside the range of the backup plate 31, it may be inside the component mounter 10 and the picker nozzle 60 by the head 50. It can be set as long as it is within the range that can be collected.

In step S216, the control device 90 determines whether the installation (placing) of all the support backup pins 35a in the first lane 20a is completed each time the support backup pins 35a are moved. If the control device 90 determines that the installation of all the support backup pins 35a scheduled to be placed on the first lane 20a has not been completed (“NO” in step S216), the control device 90 returns to step S214 and updates the layout information. Accordingly, the supporting backup pin 35a to be moved next is moved.

On the other hand, when the control device 90 determines that the installation of all the supporting backup pins 35a scheduled to be placed on the first lane 20a has been completed (determined as "YES" in step S216), the control device 90 places the support pins 35a on the first lane 20a. It is determined whether there are any extra backup pins 35 (sometimes referred to as unused backup pins 35b in this specification) that are not used to support the board S during mounting (step S218).

When the control device 90 determines in step S218 that there is an unused backup pin 35b on the backup plate 31 (particularly on the first lane 20a) (determined as "YES" in step S218), the controller 90 removes the unused backup pin 35b. 35b to storage tables 41a and 41b, which are predetermined storage locations (step S220). In this process, the availability of the storage tables 41a and 41b is checked based on the captured image obtained in step S212 and the movement information (position information) of the support backup pins 35a moved from the storage tables 41a and 41b, and the backup This is done by collecting the unused backup pins 35b to be moved on the plate 31 and placing them in vacant storage locations on the storage tables 41a and 41b.

On the other hand, if the control device 90 determines in step S218 that there is no unused backup pin 35b on the backup plate 31 (particularly on the first lane 20a) (determines "NO" in step S218), in step S222 , the storage table lifting device 43 is driven to lower the storage table 41a of the first backup pin stocker 40a and the storage table 41b of the second backup pin stocker 40b. Thereafter, in step S224, the control device 90 drives the rail moving device 28 to move the dependent rail 22a of the first lane 20a and the reference rail 21b of the second lane 20b, which are movable conveyor rails, toward the first lane 20a. , the dependent rail 22a and the reference rail 21b are moved to the center of the backup plate 31 in the board width direction (see FIG. 11D). Then, the control device 90 ends the first lane pin installation (movement) process.

In this first lane pin installation (movement) process, the backup member movement process for moving the supporting backup pin 35a was performed after the pin movement preparation process, but the pin movement preparation process and the backup member movement The processes may be performed simultaneously. In this case, in the flowchart shown in FIG. 9, the process in step S206 (lowering the storage platform 41) is omitted, and the process in step S208 (moving the

movable rails

22a, 21b) is replaced by the process in step S214 (moving the supporting backup pin 35a). It can be carried out within (transfer). For example, in step S214, the control device 90 controls the support backup pin 35a that can be moved without moving the

movable rails

22a, 21b (the support backup pin 35a is located on the first lane 20a side from the

movable rails

22a, 21b before movement). The support backup pin 35a (the movable rail before movement) cannot be moved unless the

movable rails

22a, 21b are moved to the second lane 20b side, and the

movable rails

22a, 21b are moved to the second lane 20b side. The supporting backup pin 35a) located closer to the second lane 20b than 22a and 21b is moved.

In this way, "when moving the support backup pin 35a to the placement target conveyor, one of the movable conveyor rail and the storage table is moved relative to the other", that is, "when carrying out the backup member movement process" , "Implement the pin movement preparation process" includes "Implement the pin movement preparation process before the backup member movement process" and "Implement the pin movement preparation process at the same time as the backup member movement process". It includes both meanings. The same applies to the second lane pin installation (movement) process.

(Second lane pin installation (movement) processing)
Furthermore, the second lane pin installation (movement) process will be described in detail along the flowchart shown in FIG. In the second lane pin installation (movement) process, first, the control device 90 acquires the width information of the substrate S to be transported in the second lane 20b and the layout information of the supporting backup pins 35a of the second lane 20b from the management computer. (Step S304).

Then, the control device 90 executes the pin movement preparation process described above. Specifically, in step S306, the control device 90 drives the accommodating table lifting device 43 to lower the first accommodating table 41a and the second accommodating table 41b. Further, in step S308, the control device 90 drives the rail moving device 28 to move the dependent rail 22a of the first lane 20a, which is a movable conveyor rail, and the reference rail 21b of the second lane 20b to the first lane 20a side. (See Figure 11E). At this time, the movement destinations of the subordinate rail 22a and the reference rail 21b are preferably positions other than directly above the first storage stand 41a and the second storage stand 41b (through-hole portions 31ha, 31hb), and the first storage stand 41a and the A position closer to the first lane 20a than the second storage stand 41b (through-hole portions 31ha, 31hb) is preferable.

In this way, the control device 90 moves the supporting backup pin 35a to the second lane 20b, which is the lane to be arranged and which is the lane in which the backup pin 35 is arranged, in the same manner as in steps S206 and 208 described above. Before the arrangement, one of the subordinate rail 22a and the reference rail 21b, which are movable conveyor rails, and the first storage platform 41a and the second storage platform 41b is moved relative to the other (relative movement step).

Next, in step S310, the control device 90 drives the accommodating table lifting device 43 to raise the accommodating table 41a of the first backup pin stocker 40a and the accommodating table 41b of the second backup pin stocker 40b. Furthermore, in step S312, the control device 90 images the entire range of the backup plate 31 (including the through holes 31ha and 31hb) using the mark camera 83, similarly to step S212 described above.

Subsequently, after the above-described relative movement, the control device 90 moves the backup pin 35 (supporting backup pin 35a) to the placement target lane (backup member movement (processing) step). That is, in step S314, similarly to step S214 described above, the control device 90 processes the captured image and displays the backup pins 35 placed on the storage tables 41a and 41b and the backup pins 35 placed on the backup plate 31. The supporting backup pin 35a is moved according to the layout information received in step S304 (see FIG. 11F).

In step S316, the control device 90 determines whether the installation (placing) of all the support backup pins 35a in the second lane 20b is completed each time the support backup pins 35a are moved. If the control device 90 determines that the installation of all the support backup pins 35a scheduled to be placed on the second lane 20b has not been completed (determined as "NO" in step S316), the control device 90 returns to step S314 and updates the layout information. Accordingly, the supporting backup pin 35a to be moved next is moved.

On the other hand, when the control device 90 determines that the installation of all the supporting backup pins 35a scheduled to be placed on the second lane 20b has been completed (determined as "YES" in step S316), the control device 90 places the following on the second lane 20b. It is determined whether there are any extra backup pins 35 (sometimes referred to as unused backup pins 35b in this specification) that are not used to support the board S during mounting (step S318).

When the control device 90 determines in step S318 that there is an unused backup pin 35b on the backup plate 31 (particularly on the second lane 20b) (determined as "YES" in step S318), the controller 90 removes the unused backup pin 35b. 35b to storage tables 41a and 41b, which are predetermined storage locations (step S320). This process checks the availability of the storage tables 41a and 41b based on the captured image obtained in step S312 and the movement information (including position information) of the supporting backup pins 35a moved from the storage tables 41a and 41b. This is done by collecting the unused backup pins 35b to be moved on the backup plate 31 and placing them in vacant storage locations on the storage tables 41a and 41b.

On the other hand, if the control device 90 determines in step S318 that there is no unused backup pin 35b on the backup plate 31 (particularly on the second lane 20b) (determines "NO" in step S318), in step S322 , the storage table lifting device 43 is driven to lower the storage table 41a of the first backup pin stocker 40a and the storage table 41b of the second backup pin stocker 40b. After that, in step S324, the control device 90 adjusts the interval between each conveyor of the first lane 20a and the second lane 20b to the substrate width of the substrate S to be transported. Specifically, in the second lane 20b, the control device 90 drives the rail moving device 28 based on the acquired width information of the substrate S to move the movable conveyor rail 21b located on the first lane 20a side. The substrate is moved to the second lane 20b side, and the distance between the movable conveyor rail 21b and the movable conveyor rail 22b of the second lane 20b is adjusted to the substrate width in the substrate width direction of the substrate S (see FIG. 11G). Further, in the first lane 20a, the control device 90 drives the rail moving device 28 based on the acquired width information of the substrate S to move the movable conveyor rail 22a located on the first lane 20a side to the second lane. 20b side to adjust the distance between the fixed conveyor rail 21a and the movable conveyor rail 22a of the first lane 20a to the substrate width in the substrate width direction of the substrate S (see FIG. 11G). Then, the control device 90 ends the second lane pin installation (movement) process.

In this second lane pin installation (movement) process, the backup member movement process for moving the supporting backup pin 35a was performed after the pin movement preparation process, but the pin movement preparation process and the backup member movement The processes may be performed simultaneously. In this case, in the flowchart shown in FIG. 10, the process in step S306 (lowering the storage platform 41) is omitted, and the process in step S308 (moving the

movable rails

22a, 21b) is replaced by the process in step S314 (moving the supporting backup pin 35a). It can be carried out within (transfer). For example, in step S314, the control device 90 controls the support backup pin 35a that can be moved without moving the

movable rails

22a, 21b (the support backup pin 35a is located on the second lane 20b side from the

movable rails

22a, 21b before movement). The supporting backup pin 35a (the movable rail before movement) cannot be moved unless the

movable rails

22a, 21b are moved to the first lane 20a side, and then the

movable rails

22a, 21b are moved. The support backup pin 35a) located closer to the first lane 20a than 22a and 21b is moved.

(Implementation process)
Then, in step S108, the control device 90 performs a mounting process of picking up the component P from the feeder 16 and mounting it on the board S to manufacture a mounting board. Specifically, the control device 90 first controls the substrate transport device 20 (first lane 20a or second lane 20b) to carry the substrate S into the machine. Subsequently, the control device 90 drives the plate lifting device 32 to raise the backup plate 31 and supports the loaded substrate S by the supporting backup pins 35a installed on the backup plate 31.

Next, the control device 90 drives the head moving device 70 to move the head 50 above the component supply position of the feeder 16, and causes the Z-axis actuator 55 to lower the suction nozzle 56 to supply the component to the component supply position. Collect part P. When the control device 90 picks up the part P, the control device 90 drives the head moving device 70 to move the picked part P above the parts camera 82, and the parts camera 82 images the part P.

Furthermore, the control device 90 processes the captured image, measures the adsorption deviation of the component P, and corrects the mounting position of the component P on the board S. Then, the control device 90 drives the head moving device 70 to move the sampled component P above the corrected mounting position, and drives the Z-axis actuator 55 to lower the suction nozzle 56 to move the component P onto the substrate. Implement it in S.

(1st lane pin installation (movement) process)
Next, the first lane pin installation (movement) process will be described along the flowchart shown in FIG. 13. Note that the same processes as those in the flowchart shown in FIG. 9 are given the same reference numerals, and the explanation thereof will be omitted, and different processes will be explained. After the processing in step S204, in step S406, the control device 90 drives the storage table moving device 143a and the storage table movement device 143b to move the first storage table 141a and the second storage table 141b to the first lane 20a side. It is moved to a predetermined position (indicated by a solid line in FIG. 12). At this time, the dependent rail 22a and the reference rail 21b, which are movable conveyor rails, may be moved to the second lane 20b side, or the dependent rail 22a and the reference rail 21b may not be moved. Note that after the processing in step S406, the control device 90 advances the program to step S212.

As a result, before arranging the support backup pin 35a on the first lane 20a, which is the lane to be arranged and which is the lane in which the backup pin 35 is arranged, the control device 90 controls the subordinate rail 22a, which is a movable conveyor rail, to One of the reference rail 21b, the first accommodating table 141a, and the second accommodating table 141b can be moved relative to the other (relative movement step). As a result, the control device 90 drives the head 50 to move the backup pins 35 placed on the first accommodating table 141a and the second accommodating table 141b to a predetermined support location of the backup plate 31 and place them thereon. Since there is no need to overcome obstacles such as conveyor rails during movement, all the backup pins 35 on the first storage table 141a and the second storage table 141b can be used as support backup pins 35a. It becomes possible.

Furthermore, if the control device 90 determines in step S218 that there is no unused backup pin 35b on the backup plate 31 (particularly on the first lane 20a) (determines "NO" in step S218), in step S424. , the distance between the fixed conveyor rail 21a and the movable conveyor rail 22a of the first lane 20a is adjusted to the substrate width of the substrate S in the substrate width direction. Then, the control device 90 ends the first lane pin installation (movement) process.

(Second lane pin installation (movement) processing)
Furthermore, the second lane pin installation (movement) process will be explained along the flowchart shown in FIG. 14. Note that the same processes as those in the flowchart shown in FIG. 10 are given the same reference numerals, and the explanation thereof will be omitted, and different processes will be explained. After the processing in step S304, in step S506, the control device 90 drives the storage table moving device 143a and the storage table movement device 143b to move the first storage table 141a located at a predetermined position on the first lane 20a side. Then, the second storage table 141b is moved to a predetermined position on the second lane 20b side (indicated by a broken line in FIG. 12). At this time, the first accommodating table 141a and the second accommodating table 141b are moved passing outside the dependent rail 22a and the reference rail 21b, which are movable conveyor rails. Further, the dependent rail 22a and the reference rail 21b may be moved to the first lane 20a side, or the dependent rail 22a and the reference rail 21b, which are movable conveyor rails, may not be moved. Note that after the processing in step S506, the control device 90 advances the program to step S312.

Thereby, before arranging the supporting backup pin 35a on the second lane 20b, which is the lane to be arranged and which is the lane in which the backup pin 35 is arranged, the control device 90 controls the subordinate rail 22a, which is a movable conveyor rail, to One of the reference rail 21b, the first accommodating table 141a, and the second accommodating table 141b can be moved relative to the other (relative movement step). As a result, the control device 90 drives the head 50 to move the backup pins 35 placed on the first accommodating table 141a and the second accommodating table 141b to a predetermined support location of the backup plate 31 and place them thereon. Since there is no need to overcome obstacles such as conveyor rails during movement, all the backup pins 35 on the first storage table 141a and the second storage table 141b can be used as support backup pins 35a. It becomes possible.

Further, if the control device 90 determines in step S318 that there is no unused backup pin 35b on the backup plate 31 (particularly on the second lane 20b) (determines "NO" in step S318), in step S524. , the distance between the movable conveyor rail 21b and the movable conveyor rail 22b of the second lane 20b is adjusted to the substrate width of the substrate S in the substrate width direction. Then, the control device 90 ends the second lane pin installation (movement) process.

(Operations and effects of this embodiment)

conveyors

20a and 20b. One of the

rails

21b, 22a and the storage tables 41a, 41b, 141a, 141b is moved relative to the other. According to this, the backup pins 35 can be used and arranged more efficiently in a component mounting machine having the board transport device 20 including a plurality of conveyors.

In the present embodiment, the control device 90 (control unit; steps S206, 208, 306, 308, 406, 506) controls the movable conveyor rails 21b, 22a and One of the storage tables 41a, 41b, 141a, and 141b is moved relative to the other. According to this, in one conveyor among the plurality of

lanes

20a, 20b, before the backup pin 35 is moved by the head moving device 70, one of the movable conveyor rails 21b, 22a and the storage tables 41a, 41b, 141a, 141b is moved. It becomes possible to move one relative to the other.

Further, in this embodiment, the storage tables 41a and 41b are arranged to be movable up and down at predetermined positions, and the movable conveyor rails 21b and 22a are movable above the storage tables 41a and 41b located at the predetermined positions. Placed. According to this, it becomes possible to reliably move one of the movable conveyor rails 21b, 22a and the storage tables 41a, 41b relative to the other.
