DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a production control display device according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a circuit configuration of an embodiment of the present invention, and FIG. 2 shows a front panel configuration of the embodiment. In these figures,
The production control display device 1 includes a central processing unit (CPU).
2, a liquid crystal display 4 arranged on the front panel 3, a parallel interface 5, a serial interface 6, a bar code reader 7 for reading a bar code indicating a product name, a product lot number, processing conditions, etc., and an IC of the front panel 3. An IC card recording / reproducing device 9 having a function of reading the contents of the IC card inserted from the card insertion port 8 and a function of writing recording information to the IC card is provided. Further, an operation switch 10 and a power switch 11 are arranged on the front panel 3.

Such a production control display device 1 is connected via a signal line 12 to a control system of a manufacturing facility 20 equipped with an electronic component insertion machine for mounting electronic components on a printed circuit board or an electronic component mounting machine. To be done. The manufacturing equipment 20 is equipped with various sensors, and operation information including the operating time of the manufacturing equipment from the control system of the manufacturing equipment, production information including the number of products produced, and alarm / stop information including the equipment stop time are provided. It is input to the central processing unit 2 via the parallel interface 5. The operation information may include an operation start time, an operation end time, an operation rate, a reason for stopping, etc., in addition to the operation time. Further, the production information may include the number of non-defective products, the yield, the number of defective products by reason, and the like, in addition to the number of products produced.
Further, the alarm / stop information can include a stop time for each alarm, an alarm occurrence count, a stop time for each reason, a stop count, and the like in addition to the equipment stop time.

Further, the display device 1 for production control and the manufacturing equipment 2
The personal computer 30 and the production control display device 1 are connected to each other in order to set the connection with the display device 0 and display settings. That is, the personal computer 30
And the central processing unit 2 are connected via the serial interface 6.

The bar code reader 7 is for inputting a lot number, a product name, various setting conditions and the like. Further, the IC card recording / reproducing device 9 has a lot number,
Product name, various setting conditions, or past operating information,
Production information, alarm / stop information, etc. are read from the IC card and input to the central processing unit 2, and if necessary, operation information after production processing by the central processing unit 2, production information, alarm / stop information, etc. Is recorded on an IC card.

Before displaying the operation information, the production information, the alarm / stop information, etc. on the production management display device 1 of the above embodiment, first, the dedicated software is used on the personal computer 30 to display the production management display device 1. Make settings (connection settings and display settings). That is, the connection between the production management display device 1 and the manufacturing equipment 20 is set according to the manufacturing equipment 20 to be used as in step # 1 of the flowchart of FIG. O port setting (for example, designation of I / O port connecting the both) is performed. Then, the display is set as in step # 2, the display screen of the liquid crystal display 4 is set, and the calculation formula is set (for example, the calculation formula is specified for information such as operating rate and yield). .. When the setting procedure on the personal computer 30 side is completed, the setting data is transferred to the production control display device 1 in step # 3. Thereafter, as in step # 4, the production control display device 1 side develops the received data, that is, develops each data structure and decodes the calculation formula. On the production management display device side, for example, regarding the connection setting data, a port definition table, a status type table and a counter type table for operation / production information data types, and a code type for alarm / stop information data types. Create a table and a switch type table. For the display setting data, a table of display items is created and the calculation formula is deciphered (converted into an internal code). Here, the data type and the meaning of the data type are shown in Table 1 below.

Table 1 Data type Meaning of data type * Status type Information indicating the state of the machine, for example, count data and time data * Counter type Counting information such as number of pieces, for example, count data * Code type Information that constitutes, for example, count data, time data * Switch type Information that has one of a plurality of data as data, for example, count data, time data

By executing the setting of the production management display device 1 as shown in FIG. 3 corresponding to the manufacturing equipment 20 that uses the settings, the production management display device 1 can be used for various kinds of manufacturing equipment.
Can be used, and various information required in the case of connected manufacturing equipment can be appropriately displayed on the liquid crystal display 4. 4 and 5 are both specific examples of the display screen of the liquid crystal display 4, and show the case where the manufacturing equipment is an electronic component inspection machine.

In the above embodiment, a keyboard may be used in place of the bar code reader or the IC card recording / reproducing device, and the lot number, product name, various setting conditions, etc. may be input by the keyboard. Further, the personal computer can be shared by a plurality of production control display devices.

[0016]

As described above, according to the display device for production management of the present invention, the operation information including the operation time of the manufacturing facility and the number of products produced are included in any display format desired by the user. The production information and the alarm / stop information including the equipment stop time can be appropriately displayed, and the situation of the manufacturing equipment being used can be accurately grasped. Further, by adopting a liquid crystal display, it is possible to reduce the size and weight.
