[0002]

2. Description of the Related Art Conventionally, automatic mounting machines have been widely used for mounting chip components on a mounting board. This automatic mounting machine holds a parts cassette for mounting a reel containing a chip component and supplying the chip component to the automatic mounting machine, a moving table (also referred to as Z axis) for arranging the parts cassette in a mounting order, and a mounting substrate. Along with this, it is provided with an XY table for positioning the mounted components and a plurality of heads for picking up chip components from the reels of the parts cassette and mounting them at predetermined positions on the positioned substrate.

In such a mounting machine, the mounting program controls the chip components of which parts cassettes to be mounted in which positions on the board and in which order. The parts cassettes are moved in the mounting order. Then, the chip component is adsorbed to the head and carried to a predetermined position for mounting.

FIG. 5 shows the chip component automatic mounting apparatus 1 described above.
An example is shown. The plurality of parts cassettes 2 are arranged side by side on a moving table 3 that constitutes a parts supply unit. The moving table 3 is supported by a pair of guide rods 4 so as to be movable in the length direction thereof, and is moved by a feed screw 6 driven by a motor 5.

A component holding unit 9 is provided along the circumference of a rotary table 8 which rotates intermittently around a main shaft 7, and a suction nozzle 10 for holding a chip component is provided below the component holding unit 9. I have it. The rotary table 8
A TV camera 11 is arranged at a predetermined position on the lower side, and the chip parts held by the suction nozzle 10 are recognized by the TV camera 11.

On the other hand, a mounting board 1 on which chip components are mounted
2 is arranged on the XY table 13. The table 1
3 is moved in the X-axis direction and the Y-axis direction by guide rods 14 and 15, respectively. here,
With respect to the movement of the XY table 13 in the X-axis and Y-axis directions, the parts cassette moving table 3 will be referred to as the Z-axis and will be described below.

By the way, as a setup for mounting the chip component on the mounting substrate 12 by the automatic mounting apparatus 1, a reel in which a paper type or embossed type tape containing the chip component is wound around the parts cassette 2 is used. It is necessary to load the parts cassette and load the parts cassette on the moving base 3 based on the Z-axis table.

FIG. 3 shows an example of a parts cassette and reel parts arranged on the movable table 3. In FIG. 3, the parts cassette 2 includes a reel holder 18 for holding a reel 17 around which a tape 16 containing a chip part is wound, a lock lever 19 for locking the parts cassette 2 on the moving table 3, and a reel part during mounting. And a top cover tape take-up reel 21 for taking up the top cover tape 20 from the tape 16.

Conventionally, the replacement of the reels 17 on all the parts cassettes arranged side by side on the movable table 3 is based on the Z-axis setup work instruction sheet which describes the Z-axis table of the production model as the setup, for all Z-axis. Was being replaced.

When the parts cassette 2 is replaced on all Z axes, for example, 80 parts to be mounted on one assembly part (hereinafter, also referred to as No. A), the number of times of changing the production model is 15 times,
If there are 12 mounting machines, the number of parts will be 14400 points, and it will take a lot of man-hours to actually mount reel parts, search for reel parts, create reference materials for the reel parts, and confirm the quantity of parts. It was easy to get errors such as mounting reel parts on the parts cassette wrongly, or loading the parts cassette on the mounting machine.

Therefore, as a method for solving the above problem,
A parts cassette provided with a readable / writable memory has been proposed. A mounting system using a parts cassette provided with this memory includes a terminal device (personal computer) equipped with a bar code reader and a read / write head of the memory.

The reel is provided with a component bar code label in which a part name, a remaining number of parts, a reel number, etc. are written. The bar code reader writes the information of the part bar code label into the memory, This is used as management data of reel parts loaded in the parts cassette.

The information-written parts cassette is transported to the mounting machine by the trolley, and the parts cassette is loaded on the Z-axis of the mounting machine. When the parts cassette is loaded, the parts name in the memory is compared with the parts name in the array data.
As a result, it is equipped with a warning function to prevent the parts cassette from being mounted on the mounting machine.

In the case of the above-mentioned system, although there is the above-mentioned usefulness, each time the reel is loaded in the parts cassette, the parts bar in which the parts name, the remaining number of parts, the reel number, etc. are written by the bar code reader. It is necessary to write the information of the component barcode label from the reel to which the code label is attached to the memory. Also, the price of the memory attached to the parts cassette is high, and a memory read / write head is required. In addition, a read head is required for each mounting machine to check the mounting parts for mismounting, and it is not a general-purpose equipment and it is a dedicated facility, and it must be an expensive investment for the frequency of use. .

[0015]

In the present invention, basically, as the ID unique to the parts cassette of the ID label 22, at least the combination of the parts cassette type and the parts cassette serial number (KL0900012) and the bar code thereof are described. It is sufficient for practical use.

As described above, each of the parts cassettes is given a cassette type and a serial number, an ID unique to the parts cassette, and only the specified reel component is loaded.

A system configuration of the setup method of the present invention including a mounting machine using the parts cassette 2 with the ID label 22 used in the present invention will be described below. In FIG.
A plurality of mounting machines 1 and 1 equipped with the parts cassette moving base (also referred to as Z axis) 3 are arranged. These mounting machines 1
A parts cassette trolley 24 having a plurality of shelves 23 on which the parts cassette 2 with reels is placed is arranged in the vicinity of, and can be moved between arbitrary mounting machines.

On the delivery cart 24, the parts cassette 2 with the ID label 22 to be loaded on the Z-axis of the movable table 3 and the parts cassette with the ID label 22 that has been mounted are placed on an empty shelf. The plurality of shelves 23 are given a series of numbers so that they can be arranged in order.

Further, a personal computer 25 near the mounting machine 1 or attached to the mounting machine 1 is provided, and the personal computer 25 has the ID label 22, the part number label 17a attached to the reel, and the Z-axis setup work described later. A barcode reader 26 for reading the contents of the mounting machine name barcode label 33 attached to the instruction manual 32 (FIG. 4) is attached.

Each of the personal computers 25 is connected to the host computer 27 online.
The host computer 27 can access the parts cassette database with reel 28, the Z-axis table database 29, and the production planning database 30.

Further, the host computer 27 is connected to the Z-axis setup instruction preparation terminal device 31 online. Then, by using the Z-axis setup instruction preparation terminal device 31, the parts cassette database 2 with the reel is used.
8. The Z-axis table database 29 and the production plan database 30 are accessed to receive each data, and the Z-axis setup work instruction sheet 32 (FIG. 4) based on the production plan is created, and the mounting machine operator is given the Z of the day. It is designed to hand over the axis setup work instructions. The contents of the Z-axis setup work instruction will be described later with reference to FIG.

In the above system configuration, the setup for arranging the ID-equipped parts cassette 2 in parallel with the Z-axis (moving table 3) of the mounting machine 1 will be described with reference to the flowchart shown in FIG.

<Step> Based on the delivery request list, unassigned (shortage) reel parts are taken out from the single-item shelf warehouse, the reel parts are temporarily stocked, the stocked reel parts are taken out, and the reel parts are made to correspond to the reel parts. Z-axis setup work instruction sheet 32 in the parts cassette with ID
Install based on. In this step, as will be described later, a parts cassette with a reel component that is also diverted is also unloaded (-a).

<Step> The ID label 22 of the parts cassette in which the reel parts are mounted and the label 1 of the reel 17
7a is read by the barcode reader 26. At this time, the mounting machine name is also read due to the allocation. The read parts cassette ID data, parts number data, and parts number data are stored in the parts cassette database 28 with reel.
Transfer to

<Step> Next, the parts cassettes with ID for each production model are arranged on the shelf 23 of a predetermined trolley 24, and the mounting machine name bar attached to the ID label 22 and the Z-axis setup work instruction 32. The code 33 is read and transferred to the parts cassette database with reel 28 via the host computer 28.

In the steps so far, as described above, I
Since the D label 22 and the reel component number can be read and confirmed, it is possible to eliminate a mistake in mounting the reel component on the parts cassette 2.

Further, when the parts cassette on which the reel parts are mounted is to be arranged on the serving trolley 24 for each production model number, the number is also attached to the parts cassette shelf 23 provided on the servicing trolley 24, so that it is young. It is preferable to serve the food items in order from the number. In addition, it is clarified which production model of the parts cassette is to be delivered to the delivery cart 24,
For example, by pasting the identification tag, the serving destination can be easily confirmed and the serving work can be carried out smoothly.

<Step> Next, the destination cart mounting machine is confirmed, and the catering cart 24 is moved to the mounting machine side together with the Z-axis setup work instruction document 32 (FIG. 4). It should be noted that each of the serving carts 24 is labeled with a mounting machine name in order to confirm the destination mounting machine.

<Step> After the catering truck 24 is moved to the mounting machine 1 side, the catering truck 24 is moved to the carriage 2 of the packaging machine 1, that is, the Z axis of the packaging machine 1, based on the Z-axis setup work instruction sheet 32. The predetermined parts cassette is taken out from the parts cassette shelf 23 of 24 and is replaced or mounted.

<Step> When all the parts cassettes have been mounted or replaced on the Z-axis, the ID labels 22 of all the parts cassettes are read by the bar code reader 26 and the Z-axis parts are automatically collated. This makes it possible to move the parts cassette 3
It is possible to eliminate installation mistakes on the. Further, since the last production in the plan is considered to be mounted and the number of used parts to be mounted is known for each production model, the remaining number of parts for each parts cassette subtracted from the initial number is transferred to the parts cassette database 28.

<Step> When the Z-axis collation of the parts cassette mounted on the moving table of the mounting machine is completed, mounting is started.

<Step> When the mounting of the chip parts on the mounting board of the predetermined production model is completed, the parts cassette which can be diverted to the next production model of the day according to the Z-axis setup work instruction of the other production model to be mounted on the day Without returning (
-A), The diversion parts cassette is arranged on the distribution cart 24 of the next production model and pooled on the mounting machine side (-b).

After the Z-axis is exchanged with the mounting machine and the Z-axis is checked, if the parts cassette is diverted to the mounting (-c) of another production model, the work of newly mounting the reel parts on the parts cassette is reduced. The number of steps can be reduced. Also, the parts cassette that is not diverted on the same day will be returned to the common inventory of all other mounting machines (-d).

<Step> The mounting on the planned production model of the day is completed, that is, all model production of the day based on the production plan is completed.

As is clear from the above steps, when production of all models is completed, the state of each parts cassette, that is, the number of chip parts of the parts cassette is stored in the parts cassette database with reel 28.
The creator of the Z-axis setup work instruction can determine the parts cassette that can be used for the production model after that day. Therefore, the Z-axis setup work instruction sheet for the production model based on the production plan after that day must be
It is possible to create a Z-axis setup work instruction document (FIG. 4) that is described so as to distinguish between a parts cassette that can be used for this production model and a new parts cassette.

FIG. 4 shows an example of the Z-axis setup work instruction document. The characteristics of this Z-axis setup work instruction sheet 32 are:
The parts cassette with reel is searched for the required parts cassette from the data berth 28 (Fig. 1), the parts cassette that can be used for the next production model is determined, and the parts cassette that can be used for the next production model and the new parts cassette are selected. Created to be distinguishable.

In the Z-axis setup work instruction sheet 32, for example, the Z-axis column of the parts cassette that can be used is shaded so that the operator can distinguish it from the Z-axis column of the new parts cassette.

Explaining the item name and its contents of this Z-axis setup work instruction, the item name "Z" is the Z of the moving base of the mounting machine.
Axis number, "part number" is the part number used to mount the production model, "color" is the color of the lock lever of the target parts cassette, "number" is the number of units used per mounting board, and "total" is Number x number of boards, "total number" is the total number of parts used on the mounting machine (for the current day), "address" is the number attached to the stock cart that holds the parts cassette with the target reel parts,
“Name” is the part name, “next” is the next diversion plan number, and “next Z” is the next diversion plan Z-axis number.

As shown in the above flow chart, except for newly mounting reel parts in a parts cassette,
Based on the Z-axis setup work instruction sheet 32, the parts cassette that can be diverted for the day is unloaded and placed on the serving cart.

In the above-mentioned flow, the parts cassette that has not been diverted on the day is checked for the remaining number of parts from the reel winding scale, and the parts cassette with the remaining number is returned to the parts cassette with reel inventory management section. . For parts cassettes with no remaining quantity, cassettes that require cassette accuracy management are returned to the accuracy management unit, and unnecessary cassettes are returned to the empty cassette inventory management unit. Further, when removing the reel component from the ID-equipped parts cassette, a bar code label of the number of remaining components is attached to a predetermined position of the reel and the reel is returned.

As described above, according to the present invention, basically, the work of removing the reel parts from the parts cassette arranged in parallel on the movable table of the mounting machine is not performed, and the parts cassette which can be diverted to the next production model is They are placed on the shelves of the catering cart with the identification tags attached, and are used for mounting the next production model. Therefore, since the work of changing the reel parts to the parts cassette is reduced by that much, it is possible to shorten the operation stop time of the mounting machine when the production model is switched.

[0048]

According to the present invention, since the reel parts can be used without removing the reel parts from the parts cassette which can flow to the next production model, the work of attaching a new reel to the parts cassette is eliminated. Moreover, since the parts cassettes can be installed in parallel on the mounting machine based on the Z-axis setup work instruction sheet that includes the parts cassette data that can be diverted for each production model, the mounting machine operator can easily manage the parts cassette, and The work at the time of switching can be smoothly carried out, and the downtime of the mounting machine at the time of switching the production model can be shortened.

Further, since the parts cassette for each production model can be collated based on its ID, it is possible to eliminate an error in arranging parts mounting means of the mounting machine in parallel. Further, only by collating the ID of the component supply cassette with the component number of the reel component, it is possible to prevent the mistake of newly replacing the reel component with the component cassette.

Furthermore, by managing the parts cassette ID, the parts can be searched easily, and the parts cassettes that are no longer needed by the mounting machine can be kept in common in all the mounting machines.
