DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a control system of an electronic component mounting apparatus according to an embodiment of the present invention, FIG. 2 is a flowchart showing a version management method in the electronic component mounting apparatus, FIG. (B), (c) is a display screen example of the electronic component mounting apparatus.
[0009]
First, the configuration of the control system of the electronic component mounting apparatus will be described with reference to FIG. Examples of the electronic component mounting apparatus include a bond coating apparatus, a cream solder printing apparatus, an electronic component transfer apparatus, and an appearance inspection apparatus. In FIG. 1, the CPU 1 controls the overall operation of the electronic component mounting apparatus in accordance with a control program for the main body system. The correspondence version storage unit 2 stores the version of the control program of the main body system and the correct correspondence between the control program of each unit and the ROM.
[0010]
The system version storage unit 3 as a version storage unit stores the version of the control program of each system such as the main system and the recognition system. Similarly, the ROM version storage unit 4 as a version storage unit stores the version of the ROM such as the motor control unit of each drive unit. The comparison unit 5 determines whether the current version stored in the system version storage unit 3 and the ROM version storage unit 4 is in a correct correspondence relationship with the data in the corresponding version storage unit 2. The version history storage unit 6 stores a history of version upgrades of each unit performed so far.
[0011]
The display unit 7 displays on the screen of the monitor 8 the current version type, instructions for changing to the correct version, version upgrade history of each unit, and the like. The notification means 9 notifies the monitor 8, the patrol light 10, and the buzzer 11 that the version correspondence is incorrect. The lower system 12 is controlled by the main body system, and individually controls each unit constituting the electronic component mounting apparatus such as a recognition unit that performs image recognition. The ROM 13 stores control data such as a motor that drives each unit. The lower system 12 and the ROM 13 are upgraded independently from the main system.
[0012]
Next, with reference to FIG. 2, the version confirmation process performed when the electronic component mounting apparatus is activated will be described. First, when an apparatus activation command is issued, the lower system 12 and the ROM 13 are inquired by the control program of the main body system, and the inquired version data is stored in the system version storage unit 3 and the ROM version storage unit 4 (ST1). Next, the comparison unit 5 reads out data from each storage unit, and compares the result with the data in the corresponding version storage unit 1 to determine whether or not the current version is operable (ST2). If there is no error in the correspondence and the operation is possible, the operation is shifted to the operation of the apparatus as it is (ST3).
[0013]
If it is determined in ST2 that there is an error in the correspondence relationship between the versions of any control program and it is impossible to operate, the notification unit first notifies that effect (ST4), and the current version as shown in FIG. Are displayed on the monitor 8 (ST5). Here, when it is necessary to confirm the upgrade history up to that point (ST6), the "history display" is selected, so that the upgrade history of each part is displayed as shown in FIG. 3B. It is read from the storage unit 6 and displayed (ST7).
[0014]
On the display screen, as shown in FIG. 3C, a necessary version change instruction, that is, a necessary change portion and a correct version are displayed (ST8), and the operator changes the version according to the instruction (ST9). Thereafter, the process returns to ST1 again, the version is confirmed, and if the version has been changed to the correct version, the process moves to a normal operation (ST3). The reference result of the current version and the version change instruction may be displayed at the same time. Each version of the lower system 12 and the ROM 13 may be stored in the version storage unit in advance.
[0015]
In this way, even if system maintenance such as version upgrade is performed individually for each part, version correspondence is automatically confirmed at startup, so malfunctions due to version correspondence errors are prevented. be able to.
[0016]
【The invention's effect】
According to the present invention, versions of a plurality of control programs for controlling the electronic component mounting apparatus are stored in the version storage unit in advance, and at the time of activation, the current version of each unit is compared with the correct version correspondence. As a result, when the correspondence relationship is incorrect, it is possible to immediately instruct the change to the version of the correct correspondence relationship, so that it is possible to prevent a process loss due to an incorrect version correspondence.
