Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a mounting machine group management method.

[Technical background and problems of the invention]

With the spread of FA (Factory Automation), automation is gradually progressing to advanced production lines. In the past, only a part of the production process was automated, but recently the entire process has been automated. However, these automated lines were automated production processes for only one specific model.

Recently, there has been a demand for a machine that can process a wide variety of products.

In addition, for example, the demand for printed circuit boards has rapidly increased, and the mounting of electronic components on printed circuit boards has increased from mounting coaxial and non-coaxial electronic components to mounting chip components, and more recently, there has been a demand for mounting flat packaged ICs. It is increasing every year.

In response to the demand for various types of mounting, a dedicated machine has become a multi-functional mounting machine. In other words, the specifications of the equipment become multiple.

With such a wide variety of mounting machines, a large amount of time is spent on management and operation work, resulting in a decrease in the operating rate of the equipment and a deterioration in production efficiency.

[Purpose of the invention]

The present invention provides a mounting machine group management method that includes means for converting into NC data corresponding to each automatic manufacturing apparatus and controlling the data.

[Embodiments of the invention]

Next, an embodiment in which the method of the present invention is applied to group management of a plurality of automatic electronic component mounting machines of different types will be described with reference to the drawings. Predetermined automation processes such as electronic component automatic insertion/mounting lines such as coaxial component automatic insertion machine, non-coaxial component automatic insertion machine, chip component automatic mounting machine, flat package type IC
(FP-IC) It is assumed that group management of a production line is performed using an automatic process such as an automatic parts mounting machine.

For example, the production using the automatic insertion device line includes mounting on a printed circuit board.

Approximately one month's worth of production plans for the entire factory are input and stored in the upper production control computer (1).

Furthermore, the upper product design combinator (2) includes:

Input and store electronic component mounting position data for all types of printed circuit boards.

The production planning data from the combinator (1) and the product design data from the operator (2) are sent to the group management combinator (3) as necessary. In this combination, the data and NC are used to allocate production to the mounting machine (4).
Since data and manufacturing performance data of the mounting machine are input and stored, these data are exchanged with the equipment management combiator (5) at the lower level, that is, the terminal. One combinator (5) controls, for example, four mounting machines (4).

The system functional configuration diagram of the system shown in Fig. 1 is shown in Fig. 2.

That is, the production management computer (1) outputs the production management system c21) which is the production plan for the entire factory, and the product design combinator (3) outputs the product design system 3, such as the mounting position.

The group management combination (3) includes schedule planning (c), parts management (to), allocation planning (to), performance management (to), and work instructions (to).
5), automatic programming (28), NC data management (
b), processes and outputs the DNC link (to).

The above schedule plan (c) is developed based on the production schedule of the upper level production management system and the production results of the process.

That is, it receives the production schedule planning data stored in the higher-level production control system and develops the schedule for the corresponding manufacturing process.

The above parts management (to) calculates the required amount of parts, predicts bottlenecks, manages out-of-stock items, and manages parts delivery.

In other words, it calculates the required amount of electronic components based on the number of printed circuit boards produced according to the layout plan and component data stored in the production management system, predicts bottlenecks in electronic components by comparing them with production data, and calculates shortages of electronic components. Carry out product management, etc. The above allocation plan (■) allocates production (model order and quantity) to individual mounting machines.

In other words, the load is equalized for each mounting machine based on the production schedule planning data created in Scheduling e31, and the model changeover time is
Sequence production to minimize waiting time.

The above-mentioned performance management device manages output, equipment operation, number of defects, etc. In other words, the production output and operating status (
Operation time, stop time, failure @ cause, etc.), number of defects, etc. are managed in chronological order for each mounting machine and product type, and the allocation plan, schedule plan (2), production management system CD, parts management (24J) Provide feedback to the function as necessary.

The work instruction (2) involves inserting parts, determining the replacement order, and creating a work instruction sheet.

That is, the order of inserting electronic components into the printed circuit board and the order of replacing electronic components in the mounting machine are determined for each mounting machine/production unit created in layout plan 7.

The above automatic programming (to) automatically creates NC data.

That is, NC data is automatically created based on the electronic component insertion position data on the printed circuit board stored in the upper product design system 2 and the insertion order created from the work instruction screen.

The NC data management □□□ converts the NC data format specific to the equipment of the carp into a standard format and centrally manages it as an NC database.

In other words, it manages the NC data created by automatic programming (to) and the NC data created by direct teaching on the mounting machine (4), and the NC data, which differs for each mounting machine (4), is managed by CAD/ Convert to a standard format that is easily compatible with CAM and manage 9 digits.

The DNC link (to) connects the group management Funbutal controller to the equipment group using a standard transmission procedure.

That is, there is a standard data transmission procedure between the group management combiator (3) and the equipment management computer (5), and the equipment management combiator (5) and the mounting machine (4)
), each mounting machine has a data transmission procedure conversion function, and mutually exchanges NC data, work instruction data, and manufacturing performance data.

The configuration of the DNC link (to), which has the functions of both the group management computer (3) described above and the next equipment management combinator (5), is shown in FIG.

That is, in Fig. 3, the group management computer (3) and equipment management computer (5) have a standard data transmission procedure (hatched area in the drawing), and the equipment management computer (5) and Between the mounting machines (4), data 7 for each individual mounting machine (4) is stored on the equipment management combinator (5) side.
It outputs automatic data and exchanges NC data, work instruction data, and manufacturing performance data.

In other words, the group management combiator (3) includes a user application that is the implementation content requested by the user, a user protocol that outputs data transmission procedures that are easy for the user, and a terminal management system (TMS) that performs standard terminal management of the terminal, that is, the mounting machine. ), equipment connections that instruct each equipment management computer (5) to read the contents of the mounting machine (4) handled by each equipment management computer (5), and an MCAM that outputs by standard parrot data transmission as a DM8SNO data format that stores the procedures of the equipment management system. -T

Therefore, each equipment management computer (5) has a function of converting data into the data format of the mounting machine (5) it handles.

Next, referring to FIG. 4, it is assumed that there are, for example, 21 production request jumps (Ji, 1≦i≦21) in the systems shown in FIGS. 1 and 2. That is, each production operation is illustrated with a "J" symbol and numeral as a subscript.

These production operations are selected and grouped based on data stored in the selection condition database 82, such as the shape of the printed circuit board, the similarity of electronic components, and the priority mounting machine. This selection system uses a selection algorithm to divide people into multiple selection groups (b). For example, group by delivery date, the same work content, etc.

Next, for each selection group (b), ordering C(?) is performed using data such as delivery date and model switching time stored in the condition database (to). This ordering 6
