DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a type switching support device and a type switching support method for supporting a changeover of a component supply unit in a component mounting apparatus.

[0002]

2. Description of the Related Art A component mounting apparatus for automatically mounting components on a board is provided with a component supply unit including a tape feeder, a tray, or another type of component supply unit.

[0003] The tape feeder mounts a reel on which components are taped, and is mounted at a designated position on a component supply unit. The tray stores components one by one in a plurality of recesses partitioned in a lattice shape, and a plurality of trays are stored in a magazine having a plurality of racks vertically. Then, the tray containing the desired component is pulled out of the magazine by the drawer of the component supply unit, and the component is supplied to the transfer head of the component mounting apparatus. Normally, the types of components stored in trays differ from tray to tray. This type of component mounting apparatus is configured to supply components to a transfer head based on serving data indicating which position of a tape feeder or tray containing components of which type is stored. In the case of a tape feeder, the serving data includes at least a slot number designated for each position (called a slot) on the component supply unit where the tape feeder is mounted and information indicating the type of component to be mounted on the tape feeder. In the case of,
It is at least composed of a stage number of a rack for storing a tray in a magazine and information indicating the type of a part stored in the tray.

[0004] Since the type of components to be mounted and the like differ depending on the type of board, the serving data also differs. For this reason, when changing the board to be mounted from one board (current board) to another board (next board), the serving data is replaced with that for the next board, and the components are arranged according to the serving data for the next board. It is necessary to change (set up) the arrangement of the component supply units in the supply unit.

[0005] At present, the operator performs such a setup change manually by comparing the distribution data of the component supply units.

However, in many cases, several tens to hundreds of component supply units are attached to one component supply unit, and the number of combinations of the changeovers is enormous and very complicated.

Therefore, if the operator manually changes the setup, a long time is required. During this time, the component mounting apparatus cannot perform the original mounting operation, and the productivity is greatly reduced. In addition, since the operation is complicated, the operator may make a mistake in the type and position of the component supply unit, which may cause a defective mounting result.

In order to solve such a problem, Japanese Patent Laid-Open No. 3-124100 discloses a method for supporting such a changeover.
And Japanese Patent Application Laid-Open No. 3-14914. The means disclosed in these publications compares the product type information of components required for the production of the current board with the product type information of components required for the production of the next substrate, and mounts components of the product type not required for the production of the next substrate. Then, only the component supply unit is removed from the component supply unit, and the component supply unit containing the remaining components required for the production of the next board is attached to the slot (or rack) from which the component supply unit has been removed. In this way, the work of removing and attaching the component supply unit can be minimized.

[0009]

In this type of component mounting apparatus, however, it is known that the operation efficiency of the component mounting apparatus is greatly affected by which slot (or rack) of the component supply unit the component supply unit is attached to. ing. For this reason, it is preferable to determine the mounting position of the component supply unit so that the productivity of the board, that is, the component mounting operation on the board is completed in a shorter time.

However, conventionally, since only a necessary component supply unit is newly installed in a slot from which an unnecessary component supply unit has been removed, the operation efficiency of the component mounting apparatus is not considered at all, and the productivity of the board cannot be improved. There was a problem.

Further, the device changeover support apparatus 1 provides a setup change guidance for creating setup change guidance (using a graphic user interface and showing a setup change procedure as shown in FIG. 5) from the information 12, 13, and 14 described above. Creating means 15, component supply direction information 16 indicating a component setting direction, output means 17 such as a display or a speaker for indicating the above-mentioned guidance to an operator, and audio library 1 storing audio data necessary for the guidance.
8 and a graphic library 19 for storing graphic data.

Here, each serving data indicates the arrangement of the component supply units so that the operation efficiency of the component mounting apparatus is improved, and is prepared in advance by performing a simulation or the like by an automatic data generating apparatus.

The detached part information 12 includes at least information (slot number or step number) indicating a position where a part supply unit which is not necessary for the production of the next board is attached. The relocated component information 13 includes information on the current mounting position of the component supply unit whose mounting position is to be changed among the component supply units remaining on the component supply unit,

The new component information 14 includes information indicating a type of a component to be newly set in the component supply unit and information indicating a mounting position of the component supply unit including the component of the type in the component supply unit.

The comparing means 10 has the above-mentioned detached part information 1
2. It creates setup change information in which setup change work procedure information (procedure number) is added to the relocated part information 13 and the newly installed part information 14 and outputs them to the setup change guidance creating means 15 and output means. FIG. 2 is a work procedure list displaying setup change information in a list format.

The guidance creating means 15 includes the comparing means 10
The audio data and the graphic data for instructing the work content are extracted from the audio library 18 and the graphic library 19 on the basis of the setup change information from, and the guidance is created by combining them. This guidance is sent from the guidance creation unit 15 to the component mounting apparatus 2 via the output unit 17 or the transmission unit 3, and is output from the display unit 5 or a built-in speaker.

The model switching support device of the present embodiment has the above configuration. Next, the procedure of the process will be specifically described with reference to FIGS.

In this case, the component supply unit is 1 to 10
It is assumed that each of the slots has one slot number (although the number is originally larger, but the number is set to ten for the sake of simplicity), and one component supply unit is attached to each slot.

Then, as shown in FIG.
Slot numbers 1 to 10 contain a, b, c, d, e, f,
g, h, i, j (each letter indicates a different variety)
It is assumed that a component supply unit storing components of the type is mounted.

After the setup change (next board), b, a, k, l, c, m, d, n, o,
It is assumed that a component supply unit of a type storing components of the type e is mounted.

Here, the information is contained in the serving data storage section 8 for the current board and the serving data storage section 9 for the next board which are referred to by the comparing means 10.

Next, the processing of the comparing means 10 will be described with reference to FIG. Here, in this example, the comparison unit 10 creates a work procedure list as shown in FIG.

In this list, the column of the treatment is removed,
Either move, exchange or new establishment becomes "1",
Others are “0”. Then, it means that the action of the item that becomes “1” is performed. By the way, if the removal is “1”, it is the removal part information, if the movement or replacement is “1”, it is the removal part information, and if the new installation is “1”, it is the new part information.

The target (what) column is information about which component supply unit in which slot and what type of component is stored is to be treated, and the destination (where) column is for moving, exchanging, or replacing. The slot number of the new installation destination is shown, and the column of the component supply direction shows the angle transferred from the component supply information 16.

As described above, in this example, a, b,
c, d, e, f, g, h, i, j are b, a,
The setup is changed to k, l, c, m, d, n, o, e (in slot order).

Therefore, the comparing means 10 examines in step 1 of FIG. 3 whether there is a type that is present on the current board and not present on the next board. The component supply unit storing the components of this type need only be removed. In this example,
f, g, h, i, j correspond to this.

Therefore, as shown in FIG. 2, the removal of the column of the procedure number 1 is set to "1", and registration is made to target the type f of the slot number 6 (step 2). In addition, since the removed component supply unit is not attached to the component supply unit, the value of the destination (where) column is omitted.

In the same manner, in the same manner as described above, by the processing of step 1, the type f of the slot number 7, the type h of the slot number 8, the type i of the slot number 9, and the type Removal part information indicating that the type j is to be removed is registered (FIG. 3).

When there are no more objects to be removed, the process proceeds to step 3. In step 3, it is first examined whether there is a type that can be moved to an empty slot. Here, as a result of procedures 1 to 5, slot numbers 6 to 10 are empty slots (FIG. 4).

This and the arrangement b, a, k, l, c,
By comparing m, d, n, o, and e, it can be seen that the type d of the slot number 7 and the type e of the slot number 10 can move to an empty slot. In addition, although the product c of the slot number 3 is also to be moved, at the stage of the procedure number 6,
The destination slot number 5 is occupied and cannot be moved immediately.

Therefore, in the procedure number 6, the movement is set to "1", and the registration that the type d of the slot number 4 is moved to the slot number 7 is registered (step 4). Similarly, in the procedure number 7, the movement is set to "1", and the registration that the type e of the slot number 5 is moved to the slot number 10 is registered.

At this time, as shown in FIG. 4, the slot number 5 which is the destination of the product c having the slot number 3 is an empty slot. Therefore, in the procedure number 8, the slot number 3
Is registered to be moved to slot number 5.

As described above, if step 3 is repeated, even if the destination is not an empty slot for the time being, an empty slot is created by the movement, so that all the component supply units to be moved can be processed.

However, there are some things that cannot be dealt with simply by this movement. It should be replaced. This is because there is no change in the empty slot before and after the exchange, and it cannot be identified with the movement.

In this example, the type a having the slot number 1 and the type b having the slot number 2 are to be exchanged (step 5). Therefore, a registration is made in step 9 to replace the type a of the slot number 1 with the slot number 2 (step 6).

After going through steps 1, 3, and 5,
Only empty slots in which other types should be newly installed remain (FIG. 4).

Therefore, in the procedure numbers 11 to 14, it is registered that the new type is set to "1" and the types of k, l, m, n, and o are sequentially attached to the slot numbers of 3, 4, 6, 8, and 9 ( Step 7).

Here, according to the flow of FIG. 3, all the setup change patterns can be handled, and a work procedure list (FIG. 2) based on the setup change information can be created by automatic processing.

The guidance creating means 15 creates guidance for instructing the work contents according to the procedure based on the setup change information output from the comparing means 10.

The prepared guidance is output from the display unit 5 of the component mounting apparatus 2 or the built-in speaker (or the output means 17) when the setup of the component mounting apparatus is started. Replacement is performed.

FIG. 5 shows an example of guidance.
The component name, manufacturer name, slot position (slot number) and component orientation are displayed. At the same time, a voice is output from the speaker saying "Please set the component supply unit with the component name ABC12345 in slot number 16 in the direction displayed on the monitor."

As is clear from the above description, the model switching support device of the present embodiment is created in advance not only by considering the information on the attachment / detachment of the component supply unit to / from the component supply unit but also by considering the operation efficiency of the component mounting device. Since the operator is instructed based on the information for rearranging the arranged serving data into an array, the productivity is greatly improved by shortening the setup time by reducing the work labor and improving the operation efficiency of the component mounting apparatus. be able to.

Further, since the contents of the work are accurately instructed to the worker using voices and graphics, erroneous setting of the component supply unit can be prevented, and the production of defective boards due to this can be reduced.

The present invention can be implemented with various improvements. For example, a light emitting element such as an LED is mounted near a slot or a rack where the component supply unit is to be mounted, and the light emitting element is turned on based on the setup change information to indicate the position of the component supply unit to be processed or the mounting position. You may do so. The present invention is also applicable to a component mounting apparatus of a type in which a lead extending from a component is inserted into a hole in a substrate and mounted.

[0055]

According to the present embodiment, the model switching support apparatus is capable of transmitting serving data prepared in advance in consideration of not only information on the attachment / detachment of the component supply unit to / from the component supply unit but also the operation efficiency of the component mounting apparatus. Since the operator is instructed based on the information for rearranging the arrangement, the productivity can be greatly improved by shortening the setup time by reducing the work labor and improving the operation efficiency of the component mounting apparatus.
