DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production system used for producing electronic components, and more particularly to a production system which can use a plurality of facilities having different control modes and production ages.

[0002]

2. Description of the Related Art Electronic components are manufactured by sequentially supplying necessary raw materials to production facilities arranged in the order of the manufacturing process and processing and assembling them. This production equipment is expanded for each manufacturing process as the manufacturing scale expands, enabling mass production by operating in parallel in each manufacturing process, and manufacturing time by connecting the production equipment of multiple manufacturing processes. Has been shortened. When equipment of different manufacturing processes is connected in this way, it is necessary to adjust the manufacturing capacity of each production equipment. Therefore, each production equipment is generally controlled optimally by computer control. This computer control is easy to systematize if the production facilities are unified, and can maximize the capabilities of each facility.

On the other hand, a production facility for electronic parts that has not been changed in specifications for a long period of time, even if it is introduced at the beginning of production, is still used by improving its performance and functions.
Some of these production facilities use relay sequencers and others use old-fashioned microcomputers. Due to the bulk, old-fashioned production equipment is operated separately from state-of-the-art production equipment.

Japanese Patent Application Laid-Open No. Hei 5-138511 (prior art) connects a plurality of production facilities to a personal computer via a display device and includes operation information including the operation time of each production facility and the number of products produced. There is disclosed a production management apparatus for displaying production information and alarm / stop information including equipment stoppage time on a display device in an arbitrary display format desired by an operator. This display device has parallel and serial input / output interfaces, a CPU (microprocessor) and a liquid crystal display. Each production facility is connected to the parallel interface of this display device, and an external personal computer is connected to the serial interface. Information on the production equipment is sent to a personal computer, and instructions from the personal computer are sent to each production equipment. The personal computer accumulates information sent from each production facility in a memory, analyzes the information retrieved from the memory, and displays the image. By sending the analysis data of each production facility to a display device attached to each production facility, the state of the production facility can be grasped.

In the above prior art, the output information of each display device is tabulated on a line terminal by day, week, month, etc., so that the production result management information, quality management information, and maintenance management information useful to the operator can be quickly and accurately obtained. Can be obtained.

[0006] However, the production management apparatus disclosed in the above-mentioned prior art cannot cope with an old-fashioned manufacturing facility without a parallel interface. Further, even if a manufacturing facility using a microcomputer does not have an interface with the outside, it is necessary to set up an interface and further incorporate communication software, so that the modification is costly. For this reason, these older production facilities are operated separately from the latest production facilities. In addition, there is a problem that there is no work and the number of work steps is increased.

In order to solve such a problem, the present applicant has disclosed in Japanese Patent Application No. 2000-400834 the operating state of a production facility into a plurality of states, and emits light in a predetermined emission color according to each operation section. If it has a signal light,
A production system has been proposed in which the operating state of each production facility can be ascertained by using a signal for controlling the lighting of the signal lamp.

[0008] By providing an operation time display section for measuring and displaying the elapsed time for each of the plurality of operation states of the production equipment, the operation state of each production equipment can be grasped as numerical data. This makes it easy to collect and analyze operation data of production facilities having different electric control modes.

On the other hand, a series of operations can be automated by arranging the production facilities in the order of the production process and connecting the production facilities with an automatic transfer device. Further, by arranging a large number of production facilities connected in this manner, the production can be performed. Improve the quality.
By introducing the above-mentioned production system into a manufacturing apparatus in which a series of operations is automated in this way, one worker can take charge of many production facilities, thereby further improving productivity.

[0010]

However, since a worker in charge of a production facility which is widely arranged cannot overlook all production facilities, the operator is required to deal with one production facility in which a defect has occurred. However, even if a failure occurs in another production facility, the contents of the failure cannot be confirmed until the display device of that facility is checked, and if a failure occurs in a large number of production facilities at a distance from each other at the same time. It also takes time to prioritize the response, and there is a problem that the production equipment is stopped for a long time and productivity is significantly reduced.

[0011]
