Description

Production system for producing multiple types of industrial products

The present specification relates to a production system that sequentially produces a plurality of types of industrial products, and more particularly, to a production system that generates waste in accordance with the production of industrial products.

Japanese Unexamined Patent Application Publication No. 2004-296882 describes a component mounting system for producing a component mounting board. This component mounting system has a waste box, and is configured to collect waste generated during production of a component mounting board, such as tape scraps and defective components, in the waste box. The waste collected in the waste box is collected by the worker when the waste box is full or at the beginning or end of the production day.

Usually, the component mounting system is not limited to the production of a single product, but is used for the production of multiple products. In this case, the various wastes generated in each variety are collected together in the same waste box and disposed of without distinction. In this regard, although there is no particular problem in the conventional technology, when waste generated in the production of a specific variety is disposed together with waste generated in the production of another variety, for example, confidential information is Problems such as leakage can occur. In order to avoid such a problem, it can be considered that the waste generated in the production of a specific variety is extracted from a waste box in which various kinds of waste are mixed and disposed according to a predetermined rule. However, troublesome work is required, and the missed waste may be improperly disposed of with other waste.

The above-mentioned problems are not limited to the component mounting system, but may exist in common in production systems that sequentially produce multiple types of industrial products.

In consideration of the above situation, this specification discloses a new technology regarding waste generated in an industrial product production system.

In order to solve the above problems, a production system is disclosed. This production system sequentially produces a plurality of types of industrial products including at least a first type and a second type. The production system includes storage means for storing first production specification data used for production of a first product type and second production specification data used for production of a second product type, and the first production method. Instructing means for giving a work instruction to the worker based on at least one of the specification data and the second production specification data. In at least one of the first and second production specification data, a collection rule set for waste generated in the production of the product is described. According to such a configuration, the production system can appropriately instruct the worker on the timing and / or the rule for collecting the waste according to the collection rule described in the production specification data.

The figure which shows the structure of a components mounting system typically. The figure which shows the structure of production specification data typically. The figure which shows typically the mechanical structure of a component mounting apparatus. The figure which shows typically the electrical structure of a component mounting apparatus. The table which shows an example of the collection rule defined for each kind. The figure which shows an example of the order in which a production line produces multiple types. The table which shows another example of the collection rules defined for each product type. The figure which shows an example of another example of the order in which a production line produces multiple types.

In one embodiment of the present technology, the instruction unit is based on a collection rule described in at least one of the first and second production specification data when shifting from the production of the first product type to the production of the second product type. Thus, it is preferable to give an instruction for collecting the waste to the worker. For example, when the specific collection rule is described in one of the first and second production specification data, the instruction means instructs the worker to collect the waste regardless of the collection rule described in the other. May be given. Alternatively, based on the relationship between the collection rules described in the first and second production specification data, the operator may be given a waste collection instruction.

In the above-described embodiment, the instructing means collects waste when the collection rule described in the first production specification data does not match the collection rule described in the second production specification data. Preferably instructions are given. According to such a configuration, when the collection rule differs between the waste generated in the production of the first variety and the waste generated in the production of the second variety, the production of the second variety is performed. Prior to this, the operator can be given a waste collection instruction. Thereby, it is possible to prevent the waste generated in the production of the first product from being mixed with the waste generated in the production of the second product in advance.

In the above-described embodiment, it is preferable that the instruction unit further instructs the collection rule described in the first production specification data when giving the collection instruction to the worker. According to such a configuration, the worker can collect the waste according to an appropriate collection rule.

In the embodiment described above, the production system suspends the start of production of the second variety until the collection of the waste by the worker is completed when the instruction means gives the worker a waste collection instruction. It is preferable to do. In this case, the production system may detect the completion of the collection of the waste by a sensor or wait for an instruction from the worker who has completed the collection of the waste.

In an embodiment of the present technology, the instruction unit instructs the worker about the collection rule described in the first production specification data when the worker collects the waste during the production of the first product. It is preferable. In addition, or instead, when the worker collects the waste during the production of the second product, the instruction means instructs the collection rule described in the second production specification data to the worker. Is preferred. According to such a configuration, a useful instruction can be given to the worker even when the worker collects the waste at an arbitrary timing, not only at the time of shifting the type of product to be produced.

In one embodiment of the present technology, it is preferable that the instruction unit further includes a display unit that visually displays a collection instruction to an operator. However, the instruction means is not limited to the visible display means, and may give a recovery instruction to the worker by voice or vibration.

In one embodiment of the present technology, the production system is preferably a system that produces a component mounting board in which an electronic component is mounted on a circuit board as an industrial product. In this case, it is preferable that the first and second production specification data describe a plurality of electronic components used for production of the component mounting boards of the first and second varieties, respectively. In addition, the first and second production specification data can include various types of information necessary for the production of the component mounting board.

In the above-described embodiment, the first production specification data describes the collection rule based on the electronic parts described in the first production specification data, and the second production specification data includes the first production specification data. It is preferable that the collection rule is described based on the electronic component described in the production specification data 2. In the production of a component mounting board, there are many requests that information regarding electronic components used for the component mounting board should be managed as confidential information. For that purpose, it is effective to set the collection rule based on the electronic component described in the production specification data, that is, based on the electronic component used for the component mounting board.

The component mounting system 10 according to the embodiment will be described with reference to the drawings. The component mounting system 10 is a production system that produces a plurality of types of component mounting boards. As shown in FIG. 1, the component mounting system 10 includes a data server 20, a data management device 30, and at least one production line 50. Each production line 50 is connected to the data server 20 via the telecommunication line 40 and can communicate with the data server 20.

The production line 50 includes, for example, a solder printing device 52, one or a plurality of component mounting devices 54, and an inspection device 56. The solder printing device 52 is a device that prints solder on a circuit board, and the component mounting device 54 is a device that mounts electronic components on the circuit board after solder printing. The inspection apparatus 56 is an apparatus for inspecting a circuit board on which electronic components are mounted. The data server 20 stores electronic data used by each production line 50. The data management apparatus 30 is communicably connected to the data server 20 and is used for data processing such as addition, editing, and deletion of electronic data to the data server 20.

Each production line 50 produces a component mounting board using electronic data stored in the data server 20. For example, the production specification data 100 is stored in the data server 20. As shown in FIG. 2, the production specification data 100 includes a plurality of production specification data 100a to 100e prepared for each type A to E of component mounting boards. For example, the production line 50 can produce the component mounting board of the product type A by using the production specification data 100a of the product type A, and the parts of the product type B by using the production specification data 100b of the product type B. A mounting board can be produced. The production line 50 can produce a plurality of types A to E of component mounting boards in an arbitrary order by selectively using a plurality of production specification data 100a to 100e.

In the production specification data 100, substrate data 102, a production program 104, and a collection rule 106 are described. The board data 102 is data describing a circuit board used for production of a component mounting board. The production program 104 is data describing a plurality of electronic components used for production of a component mounting board. The production program 104 describes the order of electronic components to be mounted on the circuit board, the mounting position of each electronic component, and other information. The configuration of the production specification data 100 is not particularly limited. The production specification data 100 may be electronic data that is selectively used according to the types A to E to be produced. The production specification data 100 may be data that does not include the board data 102 and the production program 104. It may be described data. The collection rule 106 described in the production specification data 100 will be described in detail later.

The component mounting device 54 will be described with reference to FIGS. However, this description shows an example of a device that generates waste in the production line 50, and is not intended to limit the production line 50 and the devices that constitute the production line 50.

As shown in FIGS. 3 and 4, the component mounting device 54 conveys the conveyor 62 that supports the circuit board 2, a plurality of component feeders 64 that supply the electronic components 4, and the electronic components 4 that are supplied by the component feeder 64. A head 66 to be mounted on the circuit board 2 on 62 is provided. The component mounting device 54 includes a moving device 68 that moves the head 66 and a camera 70 that determines whether the electronic component 4 held by the head 66 is good or bad. In addition to these, the component mounting device 54 may further include various devices such as a nozzle replacement device and a dip unit.

The component mounting device 54 includes a touch panel 80 and a control device 82. The touch panel 80 is a user interface that receives instructions from the worker, and is a display device that displays various types of information to the worker. The control device 82 controls the operation of the component mounting device 54. As shown in FIG. 4, the control device 82 includes a storage device 84 and a processing device 86. The storage device 84 stores the production specification data 100 acquired from the data server 20. The processing device 86 executes processing necessary to control the component mounting device 54 based on the production specification data 100 stored in the storage device 84.

The component mounting device 54 further includes a waste box 72, a sensor 74 that detects the amount of collected waste box, and a tape cutter 76 that cuts the tape waste 6 generated by the component feeder 64. The waste box 72 is a container for collecting waste generated in the component mounting device 54. For example, the waste box 72 can collect the tape waste 6 and the tape reel 8 generated by the component feeder 64 as waste. In addition, the waste box 72 can collect the electronic component 4 dropped from the head 66 and the electronic component 4 that has been made defective by the camera 70 as waste. The waste box 72 is an example of a collection unit that collects waste. The component mounting device 54 may include other collection units such as a waste tray, a waste conveyor, and a waste bag in addition to or instead of the waste box 72.

The waste generated on the production line 50 may contain confidential information. For example, the characteristics of the electronic component 4 used for the component mounting board may be grasped from the electronic component 4, the tape scrap 6, and the tape reel 8 collected in the waste box 72. In the production of a component mounting board, the characteristics of the electronic component 4 used can be said to be one of confidential information that should be prevented from leaking to the outside. Therefore, the waste generated in the production line 50 needs to be disposed of appropriately, thereby preventing confidential information from leaking outside. Therefore, in the component mounting system 10 of the present embodiment, the waste collection rule 106 determined for each of the types A to E is described in the production specification data 100. For example, as shown in FIG. 5, as the collection rule 106, a first rule can be set for the type A, a second rule can be set for the types B and C, and a third rule can be set for the types D and E. The collection rule 106 for each type A to E is determined mainly based on the electronic component 4 used for production of each type A to E. For example, when the same manufacturer's electronic parts are used in the types B and C, the same collection rule can be assigned.

The control device 82 gives a waste collection instruction to the worker based on the collection rule 106 of the production specification data 100. For example, as shown in FIG. 6, it is assumed that the production line 50 sequentially produces varieties A to E. In this case, the processing device 86 is described in the collection rule 106 described in the production specification data 100a of the product type A and the production specification data 100b of the product type B at the time T1 from the production of the product type A to the production of the product type B. The recovery rule 106 is compared. Then, when the two collection rules 106 do not match, the processing device 86 gives a waste collection instruction to the worker. This waste collection instruction is visually displayed using the touch panel 80. At this time, the touch panel 80 may further display the collection rule 106 of the type A before the transfer by a message (for example, “return to the manufacturer (ABC company) by bagging”).

The worker collects the waste from the waste box 72 according to the collection instruction displayed on the touch panel 80. Thereby, it is possible to prevent the wastes having different collection rules 106 from being mixed in the same waste box 72 in advance. Similar processing is performed at other time points T2, T3, and T4 at which the type of product to be produced is transferred. In the example shown in FIG. 6, a recovery instruction is given to the worker at the time T1 when the product A is changed from the product A to the product B and at the time T3 when the product C is changed to the product D. On the other hand, no recovery instruction is given to the operator at the time T2 when the product B is transferred to the product C and at the time T4 when the product D is transferred to the product E.

After giving the waste collection instruction to the worker, the control device 82 suspends the start of the production of the next product until the collection of the waste by the worker is completed. In this case, the operator can start production of the next product type by operating the touch panel 80 after completing the collection of the waste. The control device 82 can also detect the completion of waste collection by the worker based on the output signal of the sensor 74, and can start production of the next product type.

The collection of waste by workers is not limited to the above timing. For example, based on the output signal of the sensor 74, the control device 82 can give a waste collection instruction to the worker when the waste in the waste box 72 becomes full. Alternatively, the control device 82 may estimate that the waste in the waste box 72 is full when the number of times the tape cutter has been cut reaches a predetermined number of times, and give a waste collection instruction to the operator. . Furthermore, the worker may voluntarily collect the waste at an arbitrary timing. In such a case, for example, if the product A is being produced, the control device 82 instructs the operator the collection rule 106 determined for the product A, and if the product B is being produced, the control device 82 is assigned to the product B. The collection rule 106 may be instructed. Further, the control device 82 may instruct the operator of the collection rule 106 for the product type E produced at the end of the day at the end of the daily production T5, or at the start T0 of the daily production. The operator may be instructed with the collection rule 106 for the product produced last day.

Although specific examples of the present invention have been described in detail above, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.

For example, the waste collection rule 106 may not be defined for all of the plural varieties A to E. As shown in FIGS. 7 and 8, a collection rule 106 such as a “special rule” may be set for only one kind C among the plural kinds A to E. In this case, the collection rule 106 is described only in the production specification data 100c of the type C, and the collection rule 106 is not described in the

production specification data

100a, 100b, 100d, and 100e of the other types A, B, D, and E. (That is, the collection rule 106 may be blank data).

Even in the above case, the control device 82 refers to the production specification data 100 of the two types at the time of transition from the production of one type to the production of the other type. When a predetermined collection rule 106 (“special rule” in this example) is described in at least one of the two production specification data 100, the control device 82 collects the collection rule 106 of the other production specification data 100. Regardless of whether or not the operator is given instructions for collecting the waste. That is, in the production schedule illustrated in FIG. 8, a waste collection instruction is given to the worker at the time T2 when the product B is transferred to the product C and at the time T3 when the product C is transferred to the product D. As a result, only the waste generated in the production of the product C is collected separately from the waste generated in the production of the other products A, B, D, and E.

The technology described in the embodiment is not limited to the component mounting system 10 and can be widely applied to a production system for producing a plurality of types of industrial products. By applying this technology, it is possible to properly dispose of waste generated in the production system regardless of the type of industrial product to be produced, and problems such as leakage of confidential information can be avoided.

The technical elements described in the present specification or drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.
