The mounter 10 to which the temporary storage area position determination method and the temporary storage area position determination device in the backup device are applied will be described below.

The component mounter 10 is a so-called double track conveyor type component mounter and has a base 11, as shown in FIG. The component mounter 10 includes a substrate transfer device 20, a backup device 30, a component supply device 40, a component transfer device 50, and a control device 60 (temporary storage area position determining device).

The substrate transport device 20 transports the substrate S along the X-axis direction (see FIG. 1), which is a predetermined direction. The backup device 30 cooperates with the substrate transfer device 20 to position and fix the transferred substrate S. As shown in FIG. The component supply device 40 is provided on one side (or both sides) of the substrate transfer device 20 to supply components (for example, electronic components) to be mounted on the substrate S. FIG. The component transfer device 50 is arranged above these devices 20 , 30 , 40 and sucks and holds the components supplied by the component supply device 40 with the suction nozzles 55 . is automatically mounted on the substrate S which is positioned and supported by the .

The substrate transfer apparatus 20 is of a so-called double-track conveyor system, and includes first and second conveyors 21 and 22 mounted in parallel on a base 11 .

As shown in FIG. 1, the first conveyor 21 includes a pair of guide rails, namely first and second guide rails 21a and 21b. The first and second guide rails 21a and 21b extend along a first direction (X-axis direction) in which the substrate S is conveyed (conveyance direction), and extend in a second direction perpendicular to the first direction. (Y-axis direction) relative to each other.

The first conveyor 21 is provided with first and second conveyor belts 21c and 21d provided parallel to each other immediately below the first and second guide rails 21a and 21b. The first and second conveyor belts 21c and 21d support the substrate S and transport it in the transport direction.

The first guide rail 21a and the first conveyor belt 21c of the first conveyor 21 are attached to an elongated first attachment frame 21e extending along the X-axis direction, as shown mainly in FIG. Both ends of the first mounting frame 21e are fixed to the base 11 via a pair of fixed support frames 21f. The second guide rail 21b and the second conveyor belt 21d of the first conveyor 21 are attached to an elongated second attachment frame 21g extending along the X-axis direction. Both ends of the second mounting frame 21g are fixed to a pair of sliders 21k movable on a pair of rails 12 fixed to the base 11 via a pair of movement support frames 21h. The rail 12 extends along the X-axis direction.

As a result, the second guide rail 21b moves along the Y-axis direction together with the second conveyor belt 21d directly below and is positioned and fixed. Therefore, the width of the first conveyor 21 (the width in the Y-axis direction) can be changed according to the width of the substrate S to be conveyed (the width in the Y-axis direction). The first and second mounting frames 21e and 21g are provided with first and second support plates 21i and 21j that contact and support the lower surfaces of the first and second conveyor belts 21c and 21d, respectively.

As shown in FIG. 1, the second conveyor 22, like the first conveyor 21, has first and second guide rails 22a and 22b, which are a pair of guide rails. The first and second guide rails 22a and 22b extend along a first direction (X-axis direction) in which the substrate S is conveyed (conveyance direction), and extend in a second direction perpendicular to the first direction. (Y-axis direction) relative to each other. Like the second guide rail 21b of the first conveyor 21, the first and second guide rails 22a and 22b are movable along the Y-axis direction. In this manner, the first and second guide rails 22a and 22b move along the Y-axis direction together with the first and second conveyor belts (not shown) directly below and are positioned and fixed. Therefore, the width of the second conveyor 22 (the width in the Y-axis direction) can be changed according to the width of the substrate S to be transported (the width in the Y-axis direction).

As shown in FIGS. 1 and 2, the base 11 is provided with a backup device 30 that pushes up and clamps (positions and supports) the substrate S conveyed to a predetermined mounting position by the substrate conveying device 20 . The backup device 30 supports the board S from the support surface Sa on the opposite side of the component mounting surface Sb on which the components are mounted when the components are mounted on the board S being conveyed by the pair of guide rails 21a and 21b. The backup device 30 includes a substrate support unit 31 that supports the substrate S, and an elevating device 32 that elevates the substrate support unit 31 .

The substrate support unit 31 includes a backup plate 31a and a plurality of backup pins 31b. The backup plate 31a can relatively reciprocate while facing the support surface Sa of the substrate S. As shown in FIG. The backup plate 31a is formed in, for example, a square plate shape. The backup pins 31b are a plurality of backup members that can be attached to and detached from the facing surface 31a1 of the backup plate 31a facing the supporting surface Sa of the substrate S and that support the supporting surface Sa of the substrate S. As shown in FIG. For example, a magnet is provided at the lower portion (base) of the backup pin 31b, and the backup pin 31b can be detached from the opposing surface 31a1 by magnetic force. The backup pin 31b may be a hard type backup pin (shown in FIG. 2) whose tip is made of a relatively hard material (for example, a metal member) or a relatively soft material (for example, a rubber member). It consists of a soft type backup pin (not shown).

The substrate support unit 31 is composed of a rectangular backup plate having a large number of holes formed on its upper surface, and backup pins (backup members) erected in the holes so as to be insertable and removable to support the substrate S. You may do so.

The lifting device 32 is composed of, for example, an air cylinder, and includes a rod 32a to which four corners of the backup plate 31a are detachably attached, and a cylinder body 32b for advancing and retracting the rod 32a.

The backup device 30 configured in this way holds the board support unit 31 in the lowered position (indicated by the chain double-dashed line in FIG. 2) when the component is not mounted. On the other hand, when the component is mounted, that is, when the board S is conveyed to a predetermined mounting position by the board conveying device 20 and stopped (indicated by the solid line in FIG. 1 and by the two-dot chain line in FIG. 2), The backup device 30 raises the substrate support unit 31 by the lifting device 32, pushes up the substrate S from below, and holds it at the raised position (indicated by the solid line in FIG. 2). When the component mounting is completed, the backup device 30 lowers the board support unit 31 to the lowered position by the lifting device 32 .

As shown in FIG. 1, the component mounter 10 is provided with a component supply device 40 on one side (or both sides) of the board transfer device 20 . The component supply device 40 is formed by arranging a large number of detachable component supply cassettes 41 side by side. The component supply cassette 41 includes a main body 41a, a supply reel 41b provided at the rear of the main body 41a, and a component pick-up portion 41c provided at the tip of the main body 41a. A long and narrow tape (not shown) in which components are enclosed at a predetermined pitch is wound around the supply reel 41b. The component supply cassette 41 draws out the tape at a predetermined pitch, and sequentially feeds the components to the component extractor 41c. Note that the component supply device 40 may be of a tray type in which components are arranged on a tray as well as a cassette type.

As shown in FIG. 1, the component mounter 10 is provided with a component transfer device 50 above the substrate transfer device 20 (in the front direction of the drawing). The component transfer device 50 is, for example, an XY robot type. The component transfer device 50 includes a first frame 51 extending along the Y-axis direction, a second frame 52 extending along the X-axis direction, a support base 53, a mounting head 54, a cylindrical suction nozzle 55, and an imaging device 56 .

The first frame 51 is provided on the base 11 so as to be movable along the X-axis direction. The second frame 52 is provided on the first frame 51 so as to be movable along the Y-axis direction. The support base 53 is detachably attached to the second frame 52 . The mounting head 54 is provided on the support base 53 so as to be movable up and down along the Z-axis direction perpendicular to the X-axis direction and the Y-axis direction. The suction nozzle 55 is provided so as to protrude downward from the mounting head 54 . The lower end of the suction nozzle 55 sucks and holds a component or releases the sucked and held component. The image capturing device 56 captures an image of the substrate S and the backup pin 31 b from above, and the captured image data is output to the control device 60 .

Note that the component transfer device 50 can replace the suction nozzle 55 with a holding nozzle (not shown) that holds the backup pin 31b. The holding nozzle has a holding portion (engagement portion) that holds the backup pin 31b, and the holding portion detachably holds the backup pin 31b.

Further, the base 11 is provided with an imaging device 13 . The imaging device 13 monitors the state of the component sucked by the suction nozzle 55 , and image data indicating the state of the component monitored by the imaging device 13 is output to the control device 60 .

The control device 60 has a microcomputer (not shown), and the microcomputer has an input/output interface, a CPU, a RAM and a ROM (all not shown) connected via a bus. The CPU executes a predetermined program to control the mounting of components on the board, and also executes a program corresponding to the flowchart shown in FIG. The storage location is determined and the backup pin 31b is moved. The RAM temporarily stores variables necessary for executing the program, and the ROM stores the program.

As shown in FIG. 3, the control device 60 includes a substrate second direction length acquisition unit 60a, a temporary storage area second direction position determination unit 60b, a substrate first direction length acquisition unit 60c, a temporary storage area first direction position A decision unit 60d and a control unit 60e are provided.

The substrate second direction length acquisition unit 60 a acquires the substrate second direction length, which is the length of the substrate S in the second direction, from the storage device 70 or the host computer 80 . The host computer 80 collectively manages a plurality of mounters 10 .

Temporary storage area second direction position determination unit (hereinafter sometimes referred to as second direction position determination unit) 60b, based on the substrate second direction length input from substrate second direction length acquisition unit 60a, A temporary storage area second directional position (hereinafter sometimes referred to as a second directional position), which is the second directional position of the temporary storage area A1, is determined (determination unit).

The temporary storage area A1 is an area that is set each time a new job is started (or each time a new group is started by grouping a plurality of jobs). The temporary storage area A1 can be temporarily placed (stored) before the backup pins 31b are erected when the backup pins 31b are moved to the support position (planting position) of the backup pins 31b for the job to be started. area. For example, when moving the backup pin 31b of the initial mounting area A2 to the supporting position, the temporary storage area A1 temporarily stores the backup pin 31b of the initial mounting area A2. Further, when one job is completed and the next job is started, when the backup pin 31b from the old support position is moved to the new support position, the temporary storage area A1 stores backup pins that are not used at the new support position. 31b is temporarily stored. The temporary storage area A1 is an area for temporarily storing backup pins 31b that are not used for one job during the job.

The initial mounting area A2 is a predetermined area where the worker initially (first) mounts the backup pin 31b on the facing surface 31a1 (backup device 30) of the backup plate 31a. As shown in FIG. 4, the initial mounting area A2 is set on the guide rail 21a side of the pair of guide rails 21a and 21b on which the operator mounts the backup pin 31b. It is preferable that the initial mounting area A2 is provided at the end (both sides or one side) of the facing surface 31a1 along the first direction. In this embodiment, the initial mounting area A2 may be formed in a concave shape slightly lower than the facing surface 31a1, or may be formed in a projecting shape so that only the outer portion thereof is slightly higher than the facing surface 31a1.

The initial mounting area A2 is a predetermined area where the operator can easily insert and remove the backup pin 31b. Therefore, the worker can mount the backup pin 31b without hesitation, and the workability of the worker can be improved.

In addition, as shown in FIG. 4-6, the temporary storage areas A1 are preferably provided on both left and right sides (both sides along the first direction) of the board mounting position. The board mounting position is the position of the board S that is positioned and fixed in order to mount components on the board S. FIG. A hard type backup pin may be arranged in the temporary storage area A1 on one side, and a soft type backup pin may be arranged in the temporary storage area A1 on the other side. Hard type and soft type backup pins may be mixed in the temporary storage areas A1 on both sides.

Also, the temporary storage area A1 may be provided on either side.

The temporary storage area A1 is an area set on the facing surface 31a1 of the backup plate 31a. The temporary storage area A1 is an area (location, range) in which the backup pins 31b used for supporting the substrate S when mounting components on the substrate S can be temporarily stored. As shown in FIG. 4, the temporary storage area A1 is an area in which the backup pins 31b are aligned. It is a square-shaped area arranged in four pieces (four rows) in the first direction. At this time, the backup pins 31b adjacent to each other may be in contact with each other or may be arranged with a gap therebetween. The temporary storage area A1 may have another shape, for example, a circular area, or may have an irregular shape. Further, the temporary storage area A1 is not limited to 4×4, but may be an 8×2 in which 8 backup pins 31b are arranged in the second direction and only 2 in the first direction, or an 8×2 temporary storage area in which 2 backup pins 31b are arranged in the second direction. Alternatively, the cells may be arranged in a 2×8 pattern in which eight cells are arranged in the first direction.

When the second direction length of the substrate S is greater than the second direction length of the temporary storage area A1, the second direction position determination unit 60b determines that the second direction position of the temporary storage area A1 is equal to the second direction length of the temporary storage area A1. The center is determined to match the center of the substrate S in the second direction. As a result, the temporary storage area A1 is determined in the second direction central portion of the substrate S, and the backup pin 31b before being arranged in the supporting position (planting position) can be arranged in the second direction central portion of the substrate S. can. Further, generally, the supporting position of the backup pin 31b is often arranged at the center of the substrate S in the second direction in order to suppress the bending of the substrate S in the second direction. Therefore, the moving distance of the backup pin 31b in the temporary storage area A1 from the temporary storage area A1 to the support position (particularly, the support position positioned at the center of the substrate S in the second direction) can be shortened. As a result, the time for arranging the backup pin 31b to the support position can be shortened.

Specifically, for example, the second direction position determination unit 60b calculates the coordinates of the center of the substrate S in the second direction. The second direction position determination unit 60b adds half the length of the temporary storage area A1 in the second direction to the coordinates of the center of the substrate S in the second direction, Coordinates (coordinates of the end of the temporary storage area A1 on the second guide rail 21b side in the second direction) are calculated. The second direction position determination unit 60b subtracts half the length of the temporary storage area A1 in the second direction from the coordinates of the center of the substrate S in the second direction, Coordinates (coordinates of the end of the temporary storage area A1 on the side of the first guide rail 21a in the second direction) are calculated. Then, the second direction position determination unit 60b can indicate the second direction position of the temporary storage area A1 by the coordinates of one end and the other end of the temporary storage area A1 in the second direction.

The second direction position determining unit 60b divides the length of the substrates in the second direction into a plurality of ranges in stages, and sets the second direction position of the temporary storage area A1 in stages according to each range. It may be determined to the set position. For example, each range can be set to have a value that differs by the length of the temporary storage area A1 in the second direction. At this time, the set positions are set stepwise at intervals of half the length of the temporary storage area A1 in the second direction.

Specifically, as shown in FIG. 5, for example, when the substrate second direction length of the substrate S is in the range from L2a to L2b, the setting position is set to the first setting position Pa. L2a is four times the length of the temporary storage area A1 in the second direction. L2b is three times the length of the temporary storage area A1 in the second direction. The first set position Pa is set at the center of the substrate S having a substrate second direction length L2a in the substrate second direction. The first setting position Pa is set such that the center of the temporary storage area A1 is separated from the first guide rail 21a along the second direction by twice the length of the temporary storage area A1 in the second direction. This is the position of area A1. In addition, the first set position Pa may be set at the center of the substrate S having the substrate second direction length L2b in the substrate second direction.

As shown in FIG. 6, when the substrate second direction length is in the range from L2b to L2c, the set position is set to the second set position Pb. L2c is twice the length of the temporary storage area A1 in the second direction. The second set position Pb is set at the center of the substrate S in the substrate second direction, which has a length L2b in the substrate second direction. The second set position Pb is set such that the center of the temporary storage area A1 is separated from the first guide rail 21a along the second direction by a value that is 1.5 times the length of the temporary storage area A1 in the second direction. This is the position of the temporary storage area A1. Also, the Y coordinate of the temporary storage area A1 at the second set position Pb on the side of the second guide rail 21b is the same as the Y coordinate of the board S on the side of the second guide rail 21b whose length in the board second direction is L2c. be. The second setting position Pb may be set at the center of the substrate S having the substrate second direction length L2b in the substrate second direction.

As shown in FIG. 7, when the length of the board in the second direction is in the range from L2c to L2d, the end of the board S on the side of the second guide rail 21b is located at the second position of the third set position Pc (to be described later). When the guide rail 21b side end is crossed to the second guide rail 21b side, the setting position is set to the third setting position Pc. L2d is the same length as the minimum substrate length in the second direction on which components can be mounted by the mounter 10 . In this embodiment, L2d has the same length as the length of the temporary storage area A1 in the second direction. The third setting position Pc is set such that the center of the temporary storage area A1 is separated from the first guide rail 21a along the second direction by the same amount as the length of the temporary storage area A1 in the second direction. position. In addition, the third set position Pc may be set at the center of the substrate S having the substrate second direction length L2c in the substrate second direction.

In addition, when the board second direction length is in the range from L2c to L2d, and the end of the board S on the second guide rail 21b side does not exceed the end of the second guide rail 21b side of the third setting position Pc. , the set positions are preferably set as follows: For example, by setting the second direction length of the temporary storage area A1 to a smaller value (for example, changing the second direction length to half (for example, setting it to 2×8)), the new setting position The end of the second guide rail 21b can be set so as not to exceed the end of the substrate S on the second guide rail 21b side. Further, by simply moving the new setting position in the second direction, the end of the new setting position on the side of the second guide rail 21b may be set so as not to exceed the end of the substrate S on the side of the second guide rail 21b. .

As shown in FIG. 8, when the substrate second direction length is L2d, the setting position is set to the fourth setting position Pd. The fourth set position Pd is a temporary storage area set such that the center of the temporary storage area A1 is separated from the first guide rail 21a along the second direction by half the length of the temporary storage area A1 in the second direction. It is the position of A1.

If the length of the temporary storage area A1 in the second direction is greater than the length in the second direction of the minimum board on which components can be mounted by the mounter 10, the length of the board S in the second direction is equal to the length of the temporary storage area. If the length is equal to or less than the length of A1 in the second direction, the second direction position determination unit 60b determines the second direction position of the temporary storage area A1 so that the temporary storage area A1 is positioned on the side of the first guide rail 21a as much as possible. be done. Note that FIG. 9 shows a case where the length of the substrate S in the second direction is smaller than the length of the temporary storage area A1 in the second direction. As a result, the temporary storage area A1 is determined at the center of the substrate S in the second direction, and the backup pins 31b before being arranged at the supporting positions can be arranged at the center of the substrate S in the second direction. Therefore, the moving distance of the backup pin 31b in the temporary storage area A1 from the temporary storage area A1 to the support position (particularly, the support position positioned at the center of the substrate S in the second direction) can be shortened. As a result, the time for arranging the backup pin 31b to the support position can be shortened.

The area between the first guide rail 21a and the second guide rail 21b in the temporary storage area A1 is preferably used for placing backup pins 31b that are not used for supporting the substrate S. Moreover, the temporary storage area A1 is preferably set to be smaller than the length of the substrate S in the second direction.

In addition, the second direction position determination unit 60b considers not only the second direction length of the substrate S of one job (substrate product), but also the second direction length of the substrates S of a plurality of jobs, and stores the temporary storage area. A second direction position of A1 may be determined. In this case, for example, if the second direction lengths of the substrates S of a plurality of jobs that are continuously produced are different, and the second direction length of the temporary storage area A1, which is the difference between the ranges described above, is determined. ), the second direction position of the temporary storage area A1 may be determined to be the same value. Further, when the second direction lengths of substrates S for a plurality of jobs that are continuously produced are different, a temporary The second direction position of the storage area A1 may be determined.

According to this, when producing a plurality of jobs in succession, it is not necessary to change the position of the temporary storage area A1 for each job, so the efficiency of moving the backup pin 31b can be maintained at a high level. For example, compared to changing the position of the temporary storage area A1 for each job, it is necessary to move the backup pins 31b not used for supporting the substrate S in the temporary storage area A1 to a new temporary storage area A1. do not have.

In this case, it is more preferable to also consider the first direction lengths of the substrates S of a plurality of jobs.

The board first direction length acquisition unit 60c acquires the board first direction length, which is the length of the board S in the first direction, from the storage device 70 or the host computer 80 .

The temporary storage area first direction position determination unit (hereinafter sometimes referred to as the first direction position determination unit) 60d, based on the board first direction length input from the board first direction length acquisition unit 60c, A temporary storage area first directional position (hereinafter sometimes referred to as a first directional position), which is the first directional position of the temporary storage area A1, is determined (determination unit). Similar to the second direction position determination unit 60b, the first direction position determination unit 60d changes the direction in the first direction each time a new job is started (or each time a new group obtained by grouping a plurality of jobs is started).

The predetermined distance (minimum predetermined distance) is set in consideration of the stopping accuracy of the substrate S of the substrate transfer device 20 . The end of the temporary storage area A1 farther from the substrate S is a position that is separated from the end of the temporary storage area A1 closer to the substrate S by the length of the temporary storage area A1 in the first direction. The position in the first direction can be indicated by XY coordinates based on a reference point (for example, the reference point of the board S, the reference point of the component mounter 10).

Also, the predetermined distance may be set to a value larger than the minimum predetermined distance. This value is preferably set to a value that takes into consideration workability when an operator manually takes out the backup pin 31b from the supporting position.

The temporary storage area second direction position determination unit 60b and the temporary storage area first direction position determination unit 60d constitute a determination unit 60f. The determination unit 60f determines the position (first direction position and second direction position) of the temporary storage area A1.

In step S104, the control device 60 determines the second direction position through the processing of the second direction position determining section 60b described above.

Further, in step S106, the control device 60 acquires the substrate first direction length from the storage device 70 or the host computer 80 by the processing of the substrate first direction length acquisition unit 60c described above. In step S108, the control device 60 determines the first direction position by the processing of the first direction position determining section 60d described above.

According to the temporary storage area position determination device 60 according to the above-described embodiment, the determination unit 60f determines the second direction position of the temporary storage area A1 based on the length of the substrate S in the second direction. Therefore, the position of the temporary storage area A1 in the second direction is set to an appropriate position of the substrate S in the second direction (for example, the central portion of the substrate S in the second direction) based on the length of the substrate S in the second direction. It becomes possible to As a result, it is possible to shorten the time required for the backup member to move between the temporary storage area A1 and the support position of the backup pin 31b.

In the first step, the second direction position is determined by the process of step S104 (second direction position determining unit 60b) described above. In the second step, the first direction position is determined by the process of step S108 (the first direction position determination unit 60d) described above.

Further, in the first step, the length of the substrates S in the second direction is sorted into the ranges described above, and the position of the temporary storage area A1 in the second direction is set stepwise according to the ranges. preferably determined to the set position.

The predetermined distance is, for example, the minimum length of the substrate in the second direction, the length of the temporary storage area in the second direction, or the distribution of the backup pins 31b on the substrate S (in particular, the distribution of the backup pins 31b along the second direction). It can be set based on the deviation length along the second direction from the center of the two directions.
