Description

  The present invention relates to a component mounting method for mounting components on a substrate to be mounted, particularly a multi-sided printed circuit board, and a component mounting machine, and further determines the order of mounting components on the substrate to be mounted, particularly a multi-sided printed circuit board. The present invention relates to a component mounting order determination method, a component mounting order determination device, and a component mounting order determination program.

  In recent years, there has been a demand for efficient mounting of components on an object to be mounted. In particular, as shown in FIG. 16 among objects to be mounted, a small board (small board 1) having the same mounting pattern. A method of mounting components on a multi-sided printed board 1 having a plurality of small boards 2)) in the same plane has been adopted. The emphasis has been on mounting components.

  First, together with the contents indicated by the reference numerals in FIGS. 1, 2, and 16, the following will be described for mounting on the multi-sided printed circuit board 1.

・ Component mounter configuration ・ Basic operation of the component mounter ・ Basic concept for determining the mounting order ・ Conventional mounting procedure Fig. 1 is an external view of the component mounting machine, and Fig. 2 is the component mounting. FIG. 16 is a diagram showing a conventional mounting order. In the following description of the prior art, a case applied to a component mounting machine will be described as an example of a component mounting machine.
{Configuration of component mounting machine}
1: Multi-sided printed circuit board << Refer to Fig.2, Fig.12, Fig.13, Fig.16 >>
2: XY table << X and Y directions are set when installing multi-sided printed circuit board 1 and mounting components.

Loaded with
5: One-dimensional direction << Movement direction of the component supply unit 3 >>
6: Moving table << Each parts cassette 4 is mounted and mounted on the multi-sided printed circuit board 1
When wearing, it moves one-dimensionally in the direction of arrow 5. >>
7: Component mounting part << Consists of mounting head 8, suction nozzle 9, and rotating table 10
That "
8: Mounting head 9: Suction nozzle 10: Rotary table 11: Direction of rotation 103 of rotary table 103: Control unit {Basic operation of component mounting machine} (see FIG. 2)
A parts cassette 4 for supplying various parts is arranged in a straight line in the parts supply unit 3, and the parts supply unit 3 moves only in a one-dimensional direction 5 as indicated by an arrow by a moving table 6. The parts cassette 4 is loaded with a plurality of parts of the same type stored in a tape at a fixed pitch and reeled, and the parts are supplied one by one by intermittently feeding the tape at a part storage pitch. At the time of component suction, the component supply unit 3 moves so that the suction nozzle 9 matches the position of the parts cassette 4 where the component is to be sucked.

  The component mounting unit 7 is a rotary device with a fixed installation position. For example, the component mounting unit 7 includes a rotary table 10 that rotates intermittently, twelve mounting heads 8, and five suctions for each of the mounting heads 8. A nozzle 9 is provided. When the rotary table 10 of the component mounting unit 7 rotates intermittently for every arrangement pitch of the mounting head 8, the mounting head 8 moves to the component suction position of the component supply unit 3. When the suction nozzle 9 attached to the mounting head 8 picks up the component at that position, the rotary table 10 rotates intermittently in the same manner as described above, and the suction nozzle 9 that picks up the component from the component suction position of the component supply unit 3 increases. Move to the chamfered printed circuit board 1.

  Next, the XY table 2 on which the multi-sided printed board 1 is mounted moves so as to match the component mounting position on the multi-sided printed board 1 while sliding in the XY direction. Therefore, the suction nozzle 9 mounts the sucked components on the multi-sided printed board 1.

  The control unit 103 controls operations of the XY table 2, the component supply unit 3, the component mounting unit 7, and the like.

The multi-sided printed circuit board 1 has a plurality of small boards having at least the same main part of the mounting pattern in the same plane. When the mounting of the single multi-sided printed circuit board 1 is completed, each multi-sided printed circuit board 1 is finished in the final step. Divide into small substrates. As a result, a mechanism for simultaneously creating a plurality of identical small substrates is obtained.
{Basic concept in determining the mounting order}
It is necessary to minimize the amount of movement of the part supply unit 3 from one part cassette 4 to the next part cassette 4 for picking up parts. In order to move the parts supply unit 3 efficiently, if parts are continuously taken out from the same parts cassette 4 as the parts cassette 4 from which the parts have been taken out immediately before, or taken out from the parts cassette 4 immediately adjacent thereto, Tact loss and movement loss can be suppressed.

In addition, a heavy component has a larger inertial force when it is slid by the XY table 2 after mounting the component on the multi-sided printed circuit board 1 than a light component. For this reason, it is necessary to move the XY table 2 at a low speed after mounting heavy components on the multi-sided printed circuit board 1. This is because if the component is moved at a high speed, the mounted component may be displaced. Therefore, when mounting components, it is necessary to first mount a lighter component to be mounted at a high speed, and then mount a heavier component to be mounted at a lower speed to avoid positional displacement of the mounted component.
{Conventional installation order}
* Actually, the parts supply unit 3 moves in the direction opposite to the direction of the arrow shown in FIG.
The movement of the component supply unit 3 described in the text is the movement of the component suction position as viewed from the component supply unit 3 side.
Let's move.

In addition, the origin of the component supply unit 3 is a reference point for arranging the parts cassette 4 on the component supply unit 3. In the present embodiment, the origin is set at the left end of the component supply unit 3 as shown in FIG. (Not limited to this, it may be the right end of the component supply unit 3).

Step 1: As shown in FIG. 16 (A → B), the component supply unit 3 is the component supply unit before the movement is started.
3 from the initial position (origin) where the suction nozzle 9 is opposite
Move to the position where you want to remove the part. (Moving only and not wearing).
Step 2: When mounting high-speed mounting parts, as shown in (B → C, D → E) in FIG.
The product supply unit 3 sequentially installs each component of the high-speed mounting component group from end to end.
Move to supply. And within the same speed group,
Each time the plate is switched, the movement of the component supply unit 3 changes direction. (For example,
In this case, the portion of switching from the small substrate 1) to the small substrate 2). )
Step 3: At the time of mounting a low-speed mounting part, as shown in (E → F, G → H) in FIG.
The product supply unit 3 sequentially installs each component of the low-speed mounting component group from end to end.
Move to supply. And within the same speed group,
Each time the plate is switched, the movement of the component supply unit 3 changes direction. (For example,
In this case, the portion of switching from the small substrate 2) to the small substrate 1). )
Step 4: The component supply unit 3 performs an origin return operation as shown in (I → J) of FIG.
The mounting of the printed circuit board 1 is completed (see Patent Document 1).
JP-A-4-345096

  Conventionally, there has been an increasing need to consider the following in the mounting order as described above.

In the conventional mounting order, the component supply unit 3 moves each time the small board to be mounted is switched (small board 1) → small board 2) or small board 2) → small board 1)) within the same speed group.
By changing the direction to be performed in the direction opposite to the moving direction immediately before switching
The movement loss of the component supply unit 3 when the small board to be switched is suppressed
From the initial position (origin) of the parts supply unit 3 to the position where the parts are first taken out
The movement loss (A → B) remains. Therefore, the initial position of the component supply unit 3 can be changed.
In the case of a new component mounting machine, changing the initial position changes the small board to be mounted.
Movement from the initial position of the component supply unit 3 to the position where the component is first taken out (A
→ It is necessary to change the order of installation to eliminate the loss of B) (cannot be changed with the conventional one)
.

Further, not only in the multi-sided printed circuit board 1, but also when mounting a component on an object to be mounted, the same as above even when the position where the component is first taken out is set at a position different from the origin of the component supply unit 3. In addition, it is necessary to eliminate the movement loss from the initial position of the parts supply unit 3 to the position where the parts are first taken out.

In consideration of the above problems, the present invention realizes the mounting order on the multi-sided printed circuit board 1 suitable for each of the component mounter that can change the initial position of the component supply unit 3 and the component mounter that cannot be changed. An object is to provide a component mounting method, a component mounter, a component mounting order determination method, a component mounting order determination device, and a component mounting order determination program .

In order to solve the above problems, the component mounting order determination method of the present invention is:
A small board that arranges various components in an array, moves in the arrangement direction, and holds the components supplied from the component supply unit and at least the main part of the mounting pattern. In a component mounter comprising a component mounting unit that mounts the component on the main part of a multi-sided printed circuit board having a plurality of components in the same plane, a method for determining the mounting order of components by a computer,
Data that records whether or not the initial position can be changed for each type of component mounter, whether the initial position, which is the position where the component mounting unit in the component supply unit before the movement starts, can be changed. An initial position determination step for determining by referring to
An initial position setting step of changing and setting the initial position of the component supply unit to a position at which the component is first taken out in the component supply unit based on the result of the initial position determination step, and is set in the initial position setting step The component supply order is determined so as to start the movement of the component supply unit from the initial position.

According to the present invention, with the above-described configuration,
A suitable initial position can be set according to the result of the determination in the initial position determination step. For example, if the initial position can be changed according to the result of the determination in the initial position determination step, even if the position where the component is first taken out is set to a position other than the reference origin for arranging the components in the component supply unit, The initial position is set to the position where the part is first taken out. Thereby, it is possible to eliminate the movement loss from the initial position (origin) of the component supply unit to the position where the component is first taken out.

  Conventionally, the initial position of the component supply unit can be changed or not, and the initial position suitable for each has been manually set by trial and error, but in the present invention, the control unit can be changed. By determining whether or not it is possible, a component mounting method suitable for each can be quickly and automatically performed, and man-hours can be reduced and determination errors can be avoided.

  According to the present invention, it is possible to realize a mounting order on a multi-sided printed circuit board suitable for each of a component mounter that can change the initial position of the component supply unit and a component mounter that cannot be changed.

  A detailed configuration of the control unit 103 of the component mounting machine or the control unit 203 of the mounting order determination device will be described below with reference to FIGS.

As shown in FIG. 5, the control unit 103 or the control unit 203 executes the mounting order determination program 106, so that the number determination unit 501, the initial position determination unit 502, the ratio determination unit 503, the component arrangement unit 504, and the take-out position setting are performed. A unit 505, an initial position setting unit 506, and a supply order determination unit 507.
{Number determination unit 501}
It is determined whether the number of small substrates that one multi-sided printed circuit board 1 has is an odd number or an even number.

1) Look at the contents of NC program 105, detect the number of small boards, and determine whether it is even or odd. (See Figs. 6 and 7)
・ In the header section 601 of the NC program 105, the small size of the multi-sided printed circuit board 1
There is a number of boards. By looking at this data, it is determined whether it is an even number or an odd number.

As another method, in the multi-chamfer offset part 602 of the NC program 105
, Offset data for each small board (the coordinates of the reference point of each small board as shown in FIG. 7)
Indicates the offset amount (X direction, Y direction) from the origin. ) This record
The number is counted and the number of small substrates is detected to determine whether the number is even or odd.

2) As shown in FIG. 8A, the identification unit 702 attached to the multi-sided printed circuit board 1
(Anything that knows the type of printed circuit board 1 such as a bar code can be used
Are detected by a bar code reader, a recognition camera, and other detection units 701. Based on the detected contents, the number of small boards is detected to determine whether the number is even or odd.

・ In the case of a bar code, the bar code itself indicates the number of small boards.
As an example of 701, it is detected by a barcode reader. Or it's shown in Figure 8
In addition, the barcode detected by the barcode reader is stored in the storage unit 104.
The number determination unit 501 searches the board information 703 stored in the storage unit 204.
To do. As shown in FIG. 8B, the board information 703 has an NC program name.
Refers to the contents of the corresponding NC program 105 from the NC program name,
Detect the number of small boards.

3) Recognize the image of the multi-sided printed circuit board 1 with the recognition camera, and detect the number of small boards by processing the image.

  Based on the result of the determination by the sheet number determination unit 501, an extraction position setting unit 505 described later sets an extraction position according to whether the number of small boards is an even number or an odd number. When the component supply order of the component supply unit 3 in the speed group is determined by a supply order determination unit 507 (details will be described later), the switching of the component supply unit 3 in the switching from the fastest speed group to the immediately following speed group is performed. Moving loss can be eliminated. For example, as shown in <Example 5> of FIG. 12, the position at which the suction nozzle 9 first picks up the component is the position of the component arranged at the end of the highest speed group, and the end is the highest speed. Since the take-out position setting unit 505 sets the speed group so that it is located at the extreme end located immediately after the speed group, the parts are supplied when switching from the high speed group to the medium speed group. The movement loss of the part 3 does not occur at all and can be continuously supplied.

Conventionally, the determination of the number of small substrates and the setting of the take-out position are all carried out manually by trial and error, so that the number of man-hours for the worker is enormous, resulting in considerable loss time and cost. However, by providing the control unit 103 or the control unit 203 with the number determination unit 501, it is possible to easily determine the mounting order to eliminate the movement loss of the component supply unit 3 without manual operation. Reduction can be realized.
{Initial position determination unit 502}
It is determined whether the initial position of the component supply unit 3 can be changed or cannot be changed.

  As shown in FIG. 9, for the model name indicating the type of the component mounting machine, a model name identification file having data indicating whether or not each model can change the initial position is stored in the storage unit 104 (of the component mounting order determination device). In this case, the initial position determination unit 502 compares the model name of the component mounting machine to be mounted with the above data to determine whether the initial position can be changed or not. .

  If the initial position to be described later can be changed based on the result of determination by the initial position determination unit 502, the initial position setting unit 506 (details will be described later) is the first part set by the take-out position setting unit 505 (details will be described later). An initial position is set at a position for taking out (a position different from the origin of the component supply unit 3).

  Thereby, the movement loss from the initial position (origin) of the component supply unit 3 to the position where the component is first taken out can be eliminated.

Conventionally, it has been determined whether or not the initial position can be changed and the setting is performed manually by trial and error, so that the number of man-hours for the worker is enormous, resulting in considerable loss time and cost. However, since the control unit 103 or the control unit 203 includes the initial position determination unit 502, it is possible to easily determine the mounting order that minimizes the movement loss of the component supply unit 3 without human intervention. Reduction of loss cost can be realized.
{Proportion determination unit 503}
The parts of the fastest speed group (in this embodiment, the speed group of high-speed parts) grouped for each mounting speed occupy all the parts used for mounting in the area arranged in the part supply unit 3. Determine the percentage.

  As shown in FIG. 10, in the component supply unit 3, the ratio (= A1 / A) of the occupying area A1 of all the parts used by the occupying area A1 of the fastest parts in the arrangement direction of the parts cassette 4 is calculated and exceeds half. Judgment is made. The calculation of the occupied areas A and A1 is performed based on the width data of the individual parts cassettes 4 as described in detail below.

  In FIG. 10, 803 indicates an occupied area for one part cassette 4 of the fastest part, and 801 indicates an occupied area for one part cassette 4 of the lowest speed part (low speed part in this embodiment). . 802 is an installation hole for installing the parts cassette 4 in the arrangement direction at a constant pitch (P) in the component supply unit 3, and a protrusion provided on the installation surface of the parts cassette 4 to the component supply unit 3 is inserted into the installation hole 803. As a result, the parts cassette 4 is fixed to the parts supply unit 3.

  Since the parts cassette 4 for the fastest mounted parts is small in size, the width of the storage tape is small and the occupied width of the parts cassette 4 is also small, so it can be attached to the parts supply unit 3 at a pitch interval (P). However, for example, the parts cassette 4 for the fastest mounting parts has a large part, so the width of the storage tape is large and the occupied width of the parts cassette 4 is also large. Therefore, as shown in FIG. Since the occupation width to be installed in 3 does not fall within 1 pitch interval (P), it is attached to the component supply unit 3 at intervals of 2 pitches or more.

  In this way, considering the difference in the occupied width of the parts cassette 4 to be installed, considering whether the parts cassette 4 can be arranged at intervals of 1 pitch or the parts cassette 4 can only be arranged at intervals of 2 pitches, the highest speed component Occupy area A1 in which are arranged, and the occupancy area A of all parts used are calculated.

  It is assumed that the width data of the parts cassette 4 is stored in the storage unit 104 or the storage unit 204.

  The component arrangement unit 504 (details will be described later) determines the arrangement order of the components in the component supply unit 3 based on the determination result of the ratio determination unit 503. That is, when the ratio occupied by the fastest speed group exceeds half, the fastest speed groups are arranged in the order of the slowest mounting speed from the origin of the component supply unit 3 (refer to << Example 5 >> in FIG. 12). When the occupation ratio is less than half, the arrangement order of the components is determined so that the mounting order is high in order of the mounting speed from the origin of the component supply unit 3 (see << Example 7 >> in FIG. 12). Thereby, according to each said case, the movement loss from the initial position of the components supply part 3 to the position which takes out components first can be minimized.

Conventionally, the determination of whether or not the ratio occupied by the fastest speed group exceeds half, and the determination of the part arrangement order corresponding to it, were all made by trial and error. It took a huge amount of time, resulting in considerable loss time and loss costs. However, by providing the control unit 103 or the control unit 203 with the ratio determination unit 503, it is possible to easily determine the mounting order that minimizes the movement loss of the component supply unit 3, without manual intervention. Loss cost can be reduced.
{Part arrangement part 504}
The various parts are grouped according to the same mounting speed, and the speed group of the parts is arranged in the order of fast speed group or slow speed group starting from the origin of the part supply unit 3 which is a reference point for arranging the parts. The sequence order is determined as follows.
{Takeout position setting unit 505}
When the multi-sided printed circuit board 1 is mounted, the position of the part to be taken out first is set. Specifically, it is as follows.

When the number determining unit 501 determines that the number of small boards included in one multi-sided printed circuit board 1 is an even number, the position of the first component to be taken out is grouped by the component arranging unit 504 for each mounting speed. Among the parts of the fastest speed group (high speed speed group in this embodiment), the position of the part arranged at the end is located at the speed group side immediately after the fastest speed group. (For example, see << Example 5 >> in FIG. 12), and when the number determination unit 501 determines that there are an odd number of parts, the position of the part to be taken out first is the part supply that is the reference point for arranging the parts Set to the origin of part 3.
{Initial position setting unit 506}
When the result of the number determination unit 501 is an even number and the result of the initial position determination unit 502 can be changed, the initial position, which is the position where the suction nozzle 9 in the component supply unit 3 before the movement starts, is set to the highest speed. The position of the part arranged at the end of the parts of the speed group (high speed speed group in the present embodiment) and a position other than the origin of the part supply unit 3 are set. The position of the part to be extracted first set by the extraction position setting unit 505 (for example, see << Example 1 >> initial position 301 in FIG. 12).
{Supply order determination unit 507}
When components in each speed group grouped for each mounting speed are mounted on each small board of the multi-sided printed circuit board 1, the component supply unit 3 moves from one end of the speed group to the other end to supply the components. At the same time, every time the small board to be mounted is switched to the next small board, the component supply order is determined so as to change the moving direction of the component supply unit 3 to the direction opposite to the moving direction immediately before switching. Further, when the result of the sheet number determination unit 501 is an even number, the component supply unit 3 is the portion where the component mounting speed group is switched from the fastest speed group (high-speed speed group in the present embodiment) to the immediately following speed group. The parts supply order is determined so as not to change the moving direction of the parts.

  The number determination unit 501, the initial position determination unit 502, the ratio determination unit 503, the component arrangement unit 504, the take-out position setting unit 505, the initial position setting unit 506, and the supply order determination unit 507 described above are realized by software. Although the constituent elements of the control unit 103 and the control unit 203 are used, the present invention is not limited to this. For example, the constituent elements of the control unit 103 and the control unit 203 may be realized in hardware.

↓
(Step S13) This is a step of an example of the moving direction determination step. Parts supply decided in S12
In the movement order of part 3, especially the component mounting speed group has the highest speed.
In the part where the group is switched to the next speed group, the parts supply unit 3
The movement of is not changed direction, but moved in the same direction. That is
The next speed remains in the same direction as when the final part of the highest speed group is installed.
The supply order is such that the first mounting of the degree group is performed (<< Example of FIG. 12
1 to Example 4>, << Example 5 >>, << Example 7 >>).

Thereby, the large movement (movement without mounting) of the component supply unit 3 is lower.
It is possible to make it immediately before the fast parts are picked up.

In other words, there are the following merits. Vibration for large movement of parts supply unit 3
Will occur. While the vibration is occurring, parts are picked up
The suction nozzle 9 will pick up the component 401 as it is mounted at a higher speed.
The speed when going is fast, and the size of the component 401 is very small and the adsorption area
Is small, the suction nozzle 9 is likely to cause component suction mistakes
(FIG. 14). On the contrary, the suction nozzle 9 is a component when it is mounted at a lower speed.
The speed when going to pick up 402 is slow, and the size of the part 402
And the suction area is large, the suction nozzle 9 causes component suction mistakes.
It is unlikely to occur (FIG. 15).

Execution of step S13 can prevent suction mistakes due to vibrations.
In this embodiment, this is a more preferable action.
However, it is not limited to this. For example, the component supply unit 3 generates vibration.
It has a difficult structure, and its vibrations cause an adsorption error.
Otherwise, the speed group from the fastest speed group to the next speed group

End The processing procedure of the component mounting order determination program 106 as described above will be described below with reference to the flowchart of FIG. 11 and FIGS. 12 and 13 showing the specific mounting order. .

  In FIG. 12, << Example 1 >> shows a mounting order when mounting the multi-sided printed circuit board 1 having an even number of small boards using a component mounting machine capable of changing the initial position of the component supply unit 3. Further, in <Example 1>, the ratio of the high-speed mounted component to the entire component arrangement area of the component supply unit 3 is more than half.

  In the case of << Example 1 >> in FIG. 12, the following description will be made following the flowchart in FIG.

  In step S2, it is determined that the number is an even number, and the process proceeds to step S3.

  In step S3, it is determined that the initial position of the component supply unit 3 can be changed, and the process proceeds to step S4.

In step S4, the normal position (the one set at one end of the component supply unit 3) is the initial position of the normal component supply unit 3.
The parts cassettes 4 are arranged in the order of high-speed → medium-speed → low-speed
The

In step S5, the position at which components are first taken out (suction start position) is set for each mounting speed.
Parts placed at the end of the parts in the group of high-speed speeds
At the end of the middle speed group.
Set to

In step S6, the initial position of the component supply unit 3 is set to a high-speed speed group as shown in <Example 1> of FIG.
Set the position to take out the first part of the loop. That means
Among the parts of the high-speed speed group grouped according to the mounting speed
The position of the part to be placed at the end and the end to the middle speed group
Set it to be at the extreme end.
In step S12, each small board (small board 1) and small board 2) of the multi-sided printed board 1)
When installing to a small group, attach it within the same speed mounting speed group.
Each time the board is switched to the next small board, such as small board 1) → small board 2) or small board 2) → small board 1), the small board to be mounted is also cut in the moving direction of the component supply unit 3. The direction of movement just before the change is changed to the opposite direction.
In step S13, the small group first mounted on the multi-sided printed circuit board 1 in the medium speed group.
When mounting to the board (small board 2)), the moving direction of the component supply unit 3 is high speed.
Same as the moving direction of the last small board (small board 2) mounted in the speed group
The order of installation is in one direction.

  In the mounting order of <Example 1> in FIG. 12, the initial position is set to the position shown in FIG. 12, so that the movement from the origin of the component supply unit 3 to the position where the component is first taken out, that is, A loss of movement without attachment can be avoided and the attachment tact can be shortened.

  Further, the mounting order is set such that the large movement of the component supply unit 3 when the speed group is switched does not occur immediately before mounting a component in the medium speed group, but immediately before mounting a lower speed component. This is because vibration occurs when the component supply unit 3 moves greatly. This is because if the suction nozzle 9 of the component mounting unit 7 tries to suck a component to be mounted at a higher speed while the vibration is occurring, there is a possibility that the component cannot be reliably suctioned (component supply unit 3 (Refer to FIG. 14 for obstacles at the time of component adsorption due to vibration of the head). As described above, if the setting is made as described above, it is possible to avoid a component suction error due to vibration generated with the large movement of the component supply unit 3.

  As shown in step S4 of the flowchart of FIG. 11, the parts cassette 4 is placed in the group order in which the part mounting speed is fast (high speed group → medium speed group → low speed group) (<< Example 1 >>, << Example 3 >> in FIG. Or the origin of the component supply unit 3 so as to be arranged in the order of groups in which the component mounting speed is slow (low speed group → medium speed group → high speed group) (see << Example 2 >> and << Example 4 >> in FIG. 12). From the starting point. Furthermore, since the initial position of the component supply unit 3 can be freely changed regardless of the proportion of the high-speed installation component group occupying the component supply unit 3, It is possible to avoid a loss of movement up to the position where the parts are first taken out, that is, movement without attachment. (Refer to << Example 1 >> to << Example 4 >> shown in {Mounting machine capable of changing initial position of component supply unit 3} in FIG. 12).

  In the case of << Example 5 >> in FIG. 12, a description will be given below, following the flowchart in FIG.

  In step S2, it is determined that the number is an even number, and the process proceeds to step S3.

In step S3, it is determined that the initial position of the component supply unit 3 cannot be changed, and the process proceeds to step S7.

In step S8, whether the origin is the initial position of the component supply unit 3 (set to one end of the component supply unit 3)

In step S9, the position at which components are first taken out (suction start position) is set for each mounting speed.
Parts placed at the end of the parts in the group of high-speed speeds
At the end of the middle speed group.
Set to
In step S12, each small board (small board 1) and small board 2) of the multi-sided printed board 1)
When installing to a small group, attach it within the same speed mounting speed group.
The board is called small board 1) → small board 2) or small board 2) → small board 1).
Thus, each time the next small board is switched, the moving direction of the component supply unit 3 is also changed.
The direction is changed in the direction opposite to the moving direction immediately before the small substrate to be switched is switched.

In step S13, the small group first mounted on the multi-sided printed circuit board 1 in the medium speed group.
When mounting to the board (small board 2)), the moving direction of the component supply unit 3 is high speed.
Same as the moving direction of the last small board (small board 2) mounted in the speed group
The order of installation is in one direction.

  <Example 5> in FIG. 12 is an example in which the number of small boards included in the multi-sided printed circuit board 1 is an even number and the initial position of the component supply unit 3 cannot be changed. Since the ratio of occupying the component supply unit 3 is more than half, the parts cassette 4 is arranged in the order of the low speed group → the medium speed group → the high speed group starting from the origin of the component supply unit 3. Thereby, it is possible to further reduce the movement loss of the component supply unit 3 from the origin of the component supply unit 3 to the position where the component is first taken out.

  Further, the mounting order is set such that the large movement of the component supply unit 3 when the speed group is switched does not occur immediately before mounting a component in the medium speed group, but immediately before mounting a lower speed component. This is because vibration occurs when the component supply unit 3 moves greatly. This is because if the suction nozzle 9 of the component mounting unit 7 tries to suck a component to be mounted at a higher speed while the vibration is occurring, there is a possibility that the component cannot be reliably suctioned (the component supply unit 3 (Refer to FIG. 14 for obstacles at the time of component adsorption due to vibration of the head). As described above, if the setting is made as described above, it is possible to avoid a component suction error due to vibration generated with the large movement of the component supply unit 3. However, the present invention is not limited to this. For example, if the component supply unit 3 has a structure in which vibration is difficult to occur and vibration does not occur so as to cause a suction error, component supply when the speed group is switched as in <Example 6>. The large movement of the unit 3 may be set immediately before mounting a component in the medium speed group.

  <Example 7> in FIG. 12 is an example in which the number of small boards included in the multi-sided printed circuit board 1 is an even number and the initial position of the component supply unit 3 cannot be changed. Since the ratio of occupying the component supply unit 3 is less than half, the arrangement of the parts cassettes 4 is arranged in the order of high speed group → medium speed group → low speed group starting from the origin of the component supply unit 3. Thereby, it is possible to further reduce the movement loss of the component supply unit 3 from the origin of the component supply unit 3 to the position where the component is first taken out (suction start position).

  Further, the mounting order is set such that the large movement of the component supply unit 3 when the speed group is switched does not occur immediately before mounting a component in the medium speed group, but immediately before mounting a lower speed component. This is because vibration occurs when the component supply unit 3 moves greatly. This is because if the mounting nozzle of the component mounting unit 7 tries to pick up a component while the vibration is occurring, there is a risk that the component cannot be picked up reliably. (See FIG. 14). As described above, if the setting is made as described above, it is possible to avoid a component suction error due to vibration generated with the large movement of the component supply unit 3. However, the present invention is not limited to this. For example, if the component supply unit 3 has a structure in which vibration is difficult to occur, and there is no vibration enough to cause a suction error, component supply when the speed group is switched as in <Example 8>. The large movement of the unit 3 may be set immediately before mounting a component in the medium speed group.

  In the case of << Example 9 >> in FIG. 13, a description will be given below, following the flowchart in FIG.

In step S2, it is determined that the number is an odd number, and the process proceeds to step S14.
In step S14, the initial position of the component supply unit 3, that is, the origin (set to one end of the component supply unit 3)
Parts cassettes 4 are arranged in order of speed group from high speed to medium speed to low speed.
The
In step S15, when the number of small boards included in one multi-sided printed board 1 is an odd number,
At any time, the position where the parts are first taken out is the origin of the parts supply unit 3
Set to.
In step S16, each small board (small board 1), small board 2),
When mounting on a small board 3)), install it in the same speed mounting speed group.
Small board to be attached is small board 1) → small board 2) → small board 3) or small board
3) → Small board 2) → Small board 1)
The moving direction of the component supply unit 3 is also changed immediately before the small board to be mounted is switched.
The direction of movement is reversed.
In any part where the component mounting speed group is switched in step S17, the component supply is performed.
The movement of the feeder 3 is not changed direction. In other words, to the previous speed group
In the same direction as when the last small board was installed, the next speed group
Attach the first small board.

  The fact that the number of small boards included in one multi-sided printed circuit board 1 is an odd number is shown in << Example 9 >> of FIG. 13 within the same speed group, as shown in << Example 9 >> of FIG. The extraction start position (a) (adsorption start position) and the extraction end position (b) are always opposite positions. Similarly, the extraction start position (g) and the extraction end position (h) shown in << Example 10 >> of FIG. 13 are always opposite positions.

  In << Example 9 >> of FIG. 13, since the takeout start position (a) is the origin of the component supply unit 3, the takeout end position (b) comes to the boundary with the medium speed group. Therefore, a large movement (movement without mounting) loss of the component supply unit 3 at the time of switching from the high speed speed group to the medium speed group does not occur.

  On the other hand, when the take-out start position (g) is set at the boundary with the medium speed group as shown in << Example 10 >> in FIG. 13, the take-out end position (h) becomes the origin of the component supply unit 3, and the next speed The movement loss from (i) to (j) occurs at the time of switching to the group, and the movement loss from (e) to (f) also occurs in the component mounting machine whose initial position cannot be changed.

  Therefore, when the number of small boards included in one multi-sided printed circuit board 1 is an odd number, even if the initial position of the component supply unit 3 can be changed or cannot be changed, a high-speed speed group can be used. The parts cassette 4 is necessarily arranged in the order of the high-speed group → the medium-speed group → the low-speed group starting from the origin of the component mounting machine, regardless of the proportion of the parts occupying the part supply unit 3, and The extraction start position of the first speed group must be always set to the origin of the component mounting machine. By doing so, it is necessary to move the component supply unit 3 (movement without mounting) from the high-speed component mounting end position (i) to the medium-speed component mounting start position (j) as in Example 10 in FIG. Disappears.

  The determination of the mounting order in the case of the multi-sided printed board 1 has been described above. However, the present invention may be applied to those that can be applied to a mounted object other than the multi-sided printed board 1. In particular, the initial position setting unit 506 in FIG. 5 or the initial position setting process in which step S6 in FIG. 11 is taken as an example can also be applied to mounting on an object to be mounted. In this case, the initial position is set to a position where the part is first taken out, which is a position different from the origin of the part supply unit 3, and the position of any parts cassette 4 other than the origin of the part supply unit 3 is the position where the part is first taken out. In this case, the initial position can be set at that position.

As is clear from the above examples, according to the present invention,
A suitable initial position can be set according to the result of the determination in the initial position determination step. For example, if the initial position can be changed according to the result of the determination in the initial position determination step, even if the position where the component is first taken out is set to a position other than the reference origin for arranging the components in the component supply unit, The initial position is set to the position where the part is first taken out. Thereby, it is possible to eliminate the movement loss from the initial position (origin) of the component supply unit to the position where the component is first taken out.

  Conventionally, the initial position of the component supply unit can be changed or not, and the initial position suitable for each has been manually set by trial and error, but in the present invention, the control unit can be changed. By determining whether or not it is possible, a component mounting method suitable for each can be quickly and automatically performed, and man-hours can be reduced and determination errors can be avoided.

  The present invention has an effect that the time required for component mounting can be shortened and throughput can be improved, and includes, for example, a component mounter for mounting electronic components on a printed wiring board, and a plurality of component mounters It can be applied to production lines.
