As shown in FIG. 1, a flux supply unit (hereinafter, abbreviated as a flux unit) 78 is detachably attached to the feeder holding member 22. As shown in FIG. 4, in the flux unit 78, the unit body 79 is positioned on the holding member 22 such as a feeder using the positioning recesses 27a and 27b, the connector connection portion 27n, and the engagement groove 26 and is electrically It is attached in the state connected to
The flux unit 78 includes a flux storage device 80 and a flux stirring device 81, and the flux stirring device 81 includes a squeegee device 83 and a storage device moving device 85. The flux storage device 80 includes a main body 86 and a plurality of recess forming members 87, and the plurality of recess forming members 87 are fixed to the main body 86 to form a receiving recess 88. In the plurality of recess forming members 87, the depth of the housing recess 88 is changed by changing the members forming the bottom surface to ones having different thicknesses. The depth of the housing recess 88 is determined by the shape of the part or the like.
The storage device moving device 85 includes an air cylinder 90 extending generally in the y direction and a guide rail 92 extending in the y direction, and a main body 86 of the flux storage device 80 is a piston rod extending in the y direction of the air cylinder 90. While being connected to 93, it is slidably engaged with the guide rail 92. The piston rod 93 is expanded and contracted by the drive of the air cylinder 90, and the main body 86 is reciprocated along the guide rail 92 in the y direction. The movement limit of the main body 86 is detected by limit switches 95 and 96. Further, an air source (not shown) is connected to the air chamber of the air cylinder 90 via an air supply control device 97 (see FIG. 5).

  The squeegee device 83 includes a squeegee holding member 104 that holds squeegees 102 and 103 as a pair of stirring members, and a turning device 106 that turns the squeegee holding member 104. Each of the pair of squeegees 102 and 103 is in the form of a flat plate elongated in the x direction, and generally faces the squeegee holding member 104 in a wedge shape, that is, as the distance between the squeegees 102 and 103 goes downward. It is held in an inclined state in which it becomes larger in the y direction. The pivoting device 106 includes an air cylinder 107 and a pivoting drive plate 108 extending generally in the y direction, and a piston rod 109 extending in the y direction of the air cylinder 107 is connected to the upper end of the pivoting drive plate 108.

The piston rod 109 is expanded and contracted by the drive of the air cylinder 107, the rotation drive plate 108 is rotated about the pin 110, and the squeegee holding member 104 is rotated. By the rotation of the squeegee holding member 104, one of the pair of squeegees 102, 103 is selectively set to the stirring position, and the other is set to the non-stirring position. In the stirring position, the squeegee can be brought into contact with the flux stored in the housing recess 88 (it can also be brought into contact with the bottom surface of the housing recess 88). The air chamber of the air cylinder 107 is connected to the air source via the air supply control device 112 (see FIG. 5).

With the squeegee 102 in the stirring position and the squeegee 103 in the non-stirring position, the storage device moving device 85 moves the flux storage device 80 in the right direction in FIG. The rotating device 106 rotates the squeegee holding member 104 so that the squeegee 103 is in the stirring position and the squeegee 102 is in the non-stirring position, and the flux storage device 80 is moved in the left direction in FIG. As the squeegee holding member 104 is rotated and the flux storage device 80 is reciprocated, the flux is stirred by the squeegee 102, 103. As described above, in the present embodiment, the flux is stirred by moving the flux (flux accommodating device 80) without moving the squeegees 102 and 103 as the stirring members. It is referred to that the flux is stirred once when the flux storage device 80 is reciprocated once.
In the flux stirring, the flux and the stirring member may be moved relative to each other, and the flux storage device 80 may be fixed, and the squeegee 102 or 103 may be moved or both may be moved. Further, the mode of stirring is not limited, and the stirring member and the flux may be relatively rotated. For example, it is also possible to stir the flux by rotating the member that forms the bottom surface, assuming that the housing recess 88 has a circular shape in plan view. In this case, it can be considered that the member forming the bottom surface is the stirring member.

As shown in FIG. 5, the present-to-substrate operation device M includes a control device 130 mainly composed of a computer including an execution unit, a storage unit, an input / output unit, and the like. The control device 130 includes an x-axis motor 45, a y-axis motor 36, a z-axis motor 60, a positive pressure negative pressure selective supply device 59, and a camera 132 (see FIG. 1) that picks up parts held by the suction nozzle 57. Limit switches 95 and 96, air supply control devices 97 and 112, etc. are connected. The host computer C includes an execution unit, a storage unit, an input / output unit, and the like, and also includes an input device 134 operable by an operator, a display 136, and the like. The operator can input job information and the like using the input device 134 while looking at the display 136. When the display 136 has a touch panel function, the display 136 has a function as the input device 134.
Communication of information is performed between the control device 130 and the host computer C. For example, job information and the like can be supplied from the host computer C to the control device 130, and information and the like representing the state of the substrate work apparatus M can be supplied from the control device 130 to the host computer C.

In the substrate-to-board operation apparatus M, a flux use operation which is an operation using a flux and a flux non-use operation which is an operation not using the flux are performed. For example, an operation of attaching a flux to a component and attaching it to a substrate P corresponds to an operation using a flux, and an operation of attaching a flux without attaching a flux to a component corresponds to an operation not using a flux .
In the flux use operation, for example, as shown in FIGS. 6A to 6C, (d-2), and (e-2), the suction nozzle 57 holding the part Z is moved to the flux unit 78. The flux contained in the receiving recess 88 is attached to the part Z. The suction nozzle 57 is moved horizontally and vertically to a predetermined position and height of the substrate P, and the part Z to which the flux is attached by the positive pressure negative pressure selective supply device 59 is released, and the substrate P is removed. It is attached to. Thereafter, it is moved to the component feeding device 6, and after picking up the component Z, it is operated as described above.
On the other hand, as shown in FIG. 6 (d-1) and (e-1), after the flux is attached to the component Z, the squeegee holding member 104 is rotated and the flux storage device 80 is reciprocated. Thus, the flux contained in the containing recess 88 is agitated. Every time the flux is attached to the part Z, the flux is agitated, and the attachment and agitation are alternately performed. The stirring timing when the adhesion of the flux and the stirring are alternately performed is referred to as the stirring timing after the adhesion. In the present embodiment, the stirring of the flux is performed once after the adhesion of the flux to the part Z, but may be performed twice or more.

In the board-to-board operation system, a product is manufactured by performing operations in each of the plurality of board-to-board operation devices M based on production plan information (hereinafter referred to as job information).
For example, as shown in FIG. 7, when work is performed on substrate types I to VII without performing setup change, job information JOB (job information JOB 1b), JOB (2b), JOB (3b),..., JOB (7b) (a series of operations including a plurality of operations performed continuously without performing setup replacement) Can be called) in this order and continuously. As shown in FIG. 8, the series of operations includes the operation using flux and the operation not using flux, but while the operation is being performed, the flux unit 78 is attached to the holding member 22 such as a feeder. Be done. It is troublesome to attach and detach the flux unit 78 in the flux use operation and the flux non-use operation. On the other hand, when there is a margin in the slot 25 of the feeder holding member 22, the flux unit 78 is held when the JOB information is created so that there is no interference even if the flux unit 78 is not attached or detached. It is possible to keep it attached to the member 22.
However, when the flux unit 78 is attached to the holding member 22 such as a feeder during a series of operations, the flux may be dried and the quality may be poor.
Therefore, job information is created so that the flux is periodically stirred at least while the series of operations are performed.

The job information is information on an operation determined by each substrate type (referred to as operation information), and when the substrate type changes, the job information also changes. The substrate type refers to the size of the substrate, the surface (front or back) on which components of the substrate are mounted, etc., the type of components mounted on the surface of the substrate, the position, and a plurality of elements such as circuit arrangement. And at least one of the plurality of elements is a different substrate type.
Each piece of job information includes a plurality of pieces of work information to be executed in the substrate handling apparatus M with respect to a substrate type corresponding to each piece of job information. As the plurality of operation information, for example, (a) flux use information Df which is information indicating that the operation to be performed is a flux use operation, (b) a flux unit 78 is attached to a feeder etc. holding device 22 The flux unit set information Ds, which is information indicating that, and the stirring information Dm, which is information about stirring of the flux (c), etc. correspond.
(a) Flux usage information Df
As shown in FIG. 8, for example, the work represented by job information JOB (1b), JOB (3b), JOB (6b) is a flux use work, and job information JOB (2b), JOB (4b), JOB When the work represented by (5b) and JOB (7b) is a flux non-use work, flux usage information Df is included in each of job information JOB (1b), JOB (3b) and JOB (6b). The flux use information Df is not included in the job information JOB (2b), JOB (4b), JOB (5b), JOB (7b).
(b) Flux Unit Set Information As shown in FIG. 8, the flux unit set information Ds is included in all the job information JOB (1b) to JOB (7b) corresponding to the series of operations. For example, in the case where the flux unit 78 is attached to the slot 25 of the feeder holding member 22 numbered 9 in a series of operations, the flux unit set information Ds is batched for all the series of operations. Can be input (flux unit set information input process). A display image 138 of the display 136 in that case is shown in FIG. In this case, it can be considered that the flux unit set information Ds inputted collectively corresponds to the "set information" in the claims.
On the other hand, it is also possible to individually input flux unit set information Ds for all the series of operations, and in that case, a plurality of flux unit set information Ds and the like individually input It can be considered that “set information” is configured. In addition, whether or not flux unit set information Ds is input in a batch, individually input, or in any case, conceptually, in each of all job information JOB (1) to JOB (7) It can be considered that the flux unit set information Ds is included.
(c) Stirring information Dm
In the case where the flux is periodically stirred during a series of operations, the stirring information Dm includes information (for example, information representing cycle time, information representing the number of times of stirring, etc.) representing the condition of stirring. . Stirring timing is reached based on the stirring information Dm every time the cycle time elapses, and the stirring of the number of times of stirring is performed. The stirring timing in this case is referred to as a set stirring timing. Information indicating a cycle time (for example, 600 sec) and the number of times of stirring (for example, once) is input through the input device 134 according to the display image 140 of the display 136 as shown in FIG. 10 (stirring information input process) .

In the control device 130, the flux stirring program represented by the flowchart of FIG. 11 is executed every predetermined set time.
In step 1 (hereinafter abbreviated as S1. The same applies to other steps), job information JOB (ib) (i = 1, 2,...) Is read, and flux unit set information Ds is included. It is determined whether or not it is. In the present embodiment, since flux unit set information Ds is included in all the job information JOB (1b) to JOB (7b), the determination of S1 is YES. In S2, it is determined whether or not the flux usage information Df is included in the job information JOB (ib). If the read job information JOB (i) represents one of flux use work {JOB (1b), JOB (3b), JOB (6b)}, the determination is YES, and in S3, after attachment It is determined whether or not it is a stirring timing. When it is a stirring timing after adhesion, the flux is stirred in S4. On the other hand, when it is not the stirring timing after adhesion, the determination of S3 is NO, and it is determined in S5 whether or not the set stirring timing has been reached. In the case of the set agitation timing, the flux agitation is performed once in S4.
On the other hand, if the read job information JOB (i) is any of the information {JOB (2b), JOB (4b), JOB (5b), JOB (7b)} representing flux non-use work Since the flux use information Df is not included, the determination of S2 is NO. In S5, it is determined whether or not the set agitation timing is reached, and when the set agitation timing is reached, agitation is performed in S4.

As described above, since flux unit set information Ds is included in all of the job information JOB (1b) to JOB (7b) in the substrate-to-board operation system according to the present embodiment, the job information JOB (1b) ) In all the series of operations corresponding to JOB (7b), the flux unit 78 attached to the slot 25 of No. 9 is the target of agitation represented by agitation information Dm based on the flux unit set information Ds .
On the other hand, even in the conventional substrate-to-board operation system, the flux unit 78 may be attached to the holding member 22 such as a feeder during a series of operations, but flux unit set information does not use flux It was not included in the job information corresponding to the work. Therefore, while the flux non-use work was performed, the flux unit 78 was not targeted for agitation.
On the other hand, in the substrate-to-board operation system according to the present embodiment, even if the flux non-use operation is performed, since the flux unit 78 is the target of the stirring, the flux non-use operation continues for a long time. However, it is possible to suppress the drying of the flux and make it difficult for the quality to be poor. In other words, since the flux unit 78 can be attached to the holding member 22 such as a feeder, the operation of the operator can be simplified.

  Further, in the substrate handling system according to the present embodiment, both when flux is used and when flux non-use is performed, flux is stirred whenever the set agitation timing is reached, and In the case where use work is performed, stirring of the flux is performed each time the stirring timing after deposition is reached. In other words, when flux non-use work is performed, the flux is stirred each time the set agitation timing is reached, and when flux use operation is performed, each time at least one of the set agitation timing and the post-attachment agitation timing is reached. The flux is stirred. On the other hand, in the case of the substrate handling device described in Patent Document 1, when the flux using operation is performed, the flux is only stirred each time the stirring timing after adhesion is reached, and this point is different.

Furthermore, in the substrate-to-board operation system according to the present embodiment, the stirring of the flux is performed in different modes depending on whether the operation using the flux is performed or the operation not using the flux is performed. , Flux unit set information Ds and flux usage information Df. On the other hand, in the substrate handling apparatus described in Patent Document 1, as described in paragraph [0027], the stirring mode of the flux is switched according to the input of the switching command. On the other hand, in the substrate-to-board operation system according to the present embodiment, even if the switching command is not input each time, the flux is performed in a different manner depending on whether the operation using the flux is performed or the operation not using the flux is performed. Can be made to be stirred, and the operation of the operator can be made easier.
In addition, when the flux unit set information Ds can be input collectively for a series of jobs, the operator's operation can be further simplified.
As described above, in the present embodiment, the stirring controller is constituted by the portion storing the flux stirring program of the control device 130, the portion executing the same, etc., and the stirring controller is constituted by the portion storing S2 to S5 and the stirring A mode switching unit is configured.

The host computer C is not essential, and becomes unnecessary when the capability of the control device 130 (which can be represented by information processing capability, information storage capacity, and the like) is sufficient for managing job information and the like. In addition, even when a storage device and an input device are connected to the control device 130, it is unnecessary. Furthermore, the control device 130 is not essential, and the host computer C may have the functions of the control device 130.
Further, in the present embodiment, a plurality of continuous operations are performed as a series of operations without the setup change being performed. However, the series of operations may be determined in any way. For example, one or more of the flux use operation and the flux non-use operation can be included, and a plurality of operations performed continuously can be a series of operations.
As described above, the present invention can be implemented in various modifications and improvements based on the knowledge of those skilled in the art, in addition to the aspects described in the above embodiments.
