The presence or absence of the electronic component P may be inspected using the side view camera 44 instead of the component recognition camera 42, or may be inspected using both the component recognition camera 42 and the side view camera 44.
<Electrical configuration of display system>
Next, the electrical configuration of the display system 10 will be explained with reference to FIG. 5. The server 18 includes an input/output section 60, an information processing section 61, a management section 62, an information generation section 63, and an interface 64. The management section 62 includes a production information management section 68 and a terminal information management section 69.

The input/output unit 60 exchanges information with the mobile terminal 20 via wireless LAN or the like. The information input from the mobile terminal 20 to the input/output unit 60 includes a board ID as board identification information provided on board B, a machine ID as machine identification information provided in each

machine

12, 13, 14, 15, It includes a terminal ID as terminal identification information provided in the mobile terminal 20. The information output from the input/output unit 60 to the mobile terminal 20 may be information on the working status of any one of the

machines

12, 13, 14, and 15, or may be information on the working status of multiple machines. , any information can be displayed on the display unit 21 of the mobile terminal 20.

The information processing section 61 includes a conversion section 65, a condition setting section 66, and a selection section 67. The converting unit 65 converts the work status information selected by the selecting unit 67 into data (for example, image data) compatible with the mobile terminal 20. The conversion unit 65 may further thin out the selected information, for example. For example, the image shown in FIG. 8 is an example of the display information D1 before conversion, and displays information on the work status related to the error status when a component suction error occurs. If this display information D1 is displayed as it is on the display unit 21 of the mobile terminal 20, events such as the amount of information being too large and difficult to view and slow operation may occur.

Therefore, the above phenomenon can be solved by converting the display information D1 into simple display information D2 suitable for the display unit 21 of the mobile terminal 20 by the conversion unit 65. For example, as shown in the simple display information D2 in FIG. 9, there is a captured image I1 showing that no electronic component P remains in the component supply section 31, and a captured image of the lower surface side of the electronic component P sucked by the suction nozzle 41. By selecting I2 and the captured image I3 of the side surface where the electronic component P is sucked by the suction nozzle 41 and omitting other information, the amount of information can be thinned out to make it easier to see, and the operation of the mobile terminal 20 can be improved. You can avoid being late.

The selection unit 67 selects work status information associated with each ID from the production information management unit 68 based on the board ID or machine ID. That is, when the mobile terminal 20 reads the board ID, the selection unit 67 selects information on the work status of the machine involved in the work on the board B as display information D1 to be displayed on the display unit 21 of the mobile terminal 20. The information is selected from the production information management department 68. In addition, when the mobile terminal 20 reads the board ID, the selection unit 67 displays work status information related to an error status that occurred during work on the board B on which the board ID is provided, as production information. When the mobile terminal 20 reads the machine ID selected from the management unit 68, information on the work status related to the error status that occurred in the work on the board B by the machine provided with the machine ID is displayed as display information. The information is selected from the production information management department 68.

At the time of selection by the selection unit 67, the condition setting unit 66 can set in advance what kind of work status information is desired to be selected. The condition setting section 66 sets conditions (hereinafter referred to as "selection conditions") that serve as selection criteria for the selection of display information D1 by the selection section 67 based on instructions from the operator. Specifically, an instruction is input from the mobile terminal 20 to the condition setting section 66, and the condition setting section 66 sets selection conditions based on the input instruction. The selection unit 67 selects information on the instructed work status from the production information management unit 68 based on the set selection conditions. In this way, it is possible to avoid sending a huge amount of work status information to the mobile terminal 20, and it is possible to select only the information that the operator needs.

The production information management unit 68 manages information on the work status of each

machine

12, 13, 14, 15. Information is input to the production information management unit 68 from each

machine

12, 13, 14, 15 via the interface 64, and this information is stored and managed in association with at least one of the board ID and the machine ID. There is. The information input from each

machine

12, 13, 14, 15 includes printing information of the printing machine 12, mounting information of the mounting machine 13, inspection results of the inspection machine 15, and the like.

The printing information of the printing press 12 is managed by the production information management unit 68 in association with the board ID and machine ID. The mounting information of the mounting machine 13 is managed by the production information management section 68 in association with the board ID and machine ID. The mounting information of the mounting machine 13 includes information regarding mounting defects. The inspection results of the inspection machine 15 are managed by the production information management section 68 in association with the board ID and machine ID. The inspection results of the inspection machine 15 include defect information such as mounting defects.

The information generation unit 63 generates processed data based on information managed by the production information management unit 68. That is, the production information management section 68 stores a large amount of pre-processing information, and the information generation section 63 reads the large amount of pre-processing information stored in the production information management section 68 to generate processing data. . This processed data is inputted again to the production information management section 68 by the information generation section 63 and is stored therein. The pre-processing information is, for example, information indicating whether or not the electronic components P were successfully suctioned, and the processing data is, for example, data on the suction rate when a plurality of electronic components P are suctioned. If processed data is generated based on a large number of unprocessed information in this way, it will be easier to see than a large number of unprocessed information. The information generation unit 63 may make the numerical data of the machine management information easier to view by, for example, graphing it in chronological order. Further, the information generation unit 63 may display information on the work status when the machine is abnormal (work information on the error) in comparison with information on the work status when the machine is normal.

The terminal information management unit 69 manages the terminal ID of the mobile terminal 20. When a terminal ID is input to the input/output unit 60, if this terminal ID is a terminal ID managed by the terminal information management unit 69, information on the work status selected by the selection unit 67 is output to the mobile terminal 20. be done. On the other hand, when the input terminal ID is not a terminal ID managed by the terminal information management section 69, the selection operation by the selection section 67 is not performed, and the display section 21 of the mobile terminal 20 shows that the mobile terminal 20 is not managed. A warning will be displayed indicating that this is the case.

<Display system overview>
FIG. 6 shows how, when the inspection machine 15 detects an error such as a mounting defect, the mobile terminal 20 reads the board ID of the component mounting board PB on which the error has occurred. When the mobile terminal 20 reads the board ID, information about the machine involved in the work on the board B where the error occurred is displayed on the display unit 21 of the mobile terminal 20. The operator can identify the cause of the error occurrence at the production site based on the information displayed on the display unit 21.

The display unit 21 displays information such as the suction rate of the feeder in use and the nozzle in use, the maintenance history of the feeder in use and the nozzle in use, the captured image of the nozzle in use, and the suction image of the component. For example, by checking the captured image of the nozzle in use before starting work, it is possible to discover whether there is foreign matter attached or chipping at the tip. The operator determines whether the error is due to equipment maintenance from the information displayed on the display unit 21 of the mobile terminal 20, and if the error is due to lack of maintenance, replaces the equipment with one that has been maintained. For example, in the case of the suction nozzle 41, it is determined whether maintenance is insufficient if the number of times the suction nozzle 41 performs suction is greater than a preset threshold.

<Display system processing procedure>
Next, the processing procedure of the display system 10 will be explained with reference to the flowchart of FIG. When the board ID of board B is imaged by the camera mounted on the mobile terminal 20 (see FIG. 6), the board ID is read into the mobile terminal 20 (step S10). When the terminal ID of the mobile terminal 20 is input to the input/output section 60, the input terminal ID is sent to the terminal information management section 69. If the input terminal ID matches the terminal ID managed by the terminal information management unit 69, it is determined that the mobile terminal 20 is a registered terminal (YES in step S11); if they do not match, It is determined that the mobile terminal 20 is not a registered terminal (NO in step S12). If it is determined that the mobile terminal 20 is not a registered terminal, the process ends without accepting input of the board ID from the mobile terminal 20.

If it is determined that the mobile terminal 20 is a registered terminal, the board ID is input from the mobile terminal 20 to the input/output unit 60 (step S12). If it is determined that the board B is the one in which the error occurred based on the input board ID (YES in step S13), the selection unit 67 selects information necessary for analyzing the cause of the error from the production information management unit 68 ( Step S14). On the other hand, if it is determined that the board B is not an error board based on the input board ID (NO in step S13), information regarding the machine used to produce the board B that read the board ID is stored in the production information management. All information is acquired from the unit 68 (step S15).

The information selected from the production information management section 68 or all the information acquired from the production information management section 68 is converted by the conversion section 65 into simple display information D2 suitable for displaying on the display section 21 of the mobile terminal 20. (Step S16), this simple display information D2 is transmitted from the input/output unit 60 to the mobile terminal 20 (Step S17). In this way, information on the working status of the machine is displayed on the display section 21 of the mobile terminal 20 as simple display information D2 (see FIG. 6).
