[0022]
Next, the power supply control system will be described with reference to FIG. The power supply control system supplies power only to the minimum necessary mechanical parts to which power is supplied during work performed with the door 8 provided in the cover case 6 open, such as during maintenance work of the electronic component mounting apparatus. The safety of the worker is ensured by automatically controlling the connection and disconnection of the power supply circuit so as to be supplied.
[0023]
In FIG. 4, work modules 1, 2, 3,... N are work modules listed in FIG. 3, and a plurality of motors (1, 2,. .) And pneumatically driven cylinders (1, 2,...). These motors are driven by the motor drive unit 22, and driving power is supplied from the power supply unit 20 to the motor drive unit 22 through a power supply circuit connected and disconnected by the circuit connection / disconnection device 21. Similarly, electric power for the control operation of the valve drive unit 23 that controls supply of compressed air to the cylinder is also supplied through an electric power supply circuit connected and disconnected by the circuit connecting / disconnecting device 21.
[0024]
The circuit connecting / disconnecting device 21 is provided with switches (21-1, 21-2,...) That individually connect and disconnect the power supply to each work module. The circuit connecting / disconnecting device 21 (circuit connecting / disconnecting means) is connected to the interlock circuit 24. The CPU 25 controls the interlock circuit 24 to connect / disconnect the switches (21-1, 21-2,...). Can be controlled arbitrarily and individually.
[0025]
A door open / close detection switch 27 and an operator identification switch 28 are connected to the hardware circuit constituting the interlock circuit 24. The door open / close detection switch 27 is a micro switch for open / close detection provided on the door 8 of the cover case 6. When the operator opens the door 8, the circuit connecting / disconnecting device 21 is operated by the hardware circuit of the interlock circuit 24. Is to be activated.
[0026]
The operator identifying switch 28 is a switch that can be operated only by a key possessed by a specific worker who is recognized as a skilled worker having the skill to perform apparatus maintenance work, adjustment work, and the like. Has an interlock release function that prevents the interlock circuit 24 from operating even when door opening is detected. As will be described below, this interlock release function can select either a total release that releases the interlock as a whole, or a partial release that allows the operation of a specific work module while prohibiting other ranges of operation. It has become.
[0027]
That is, the connection / disconnection mode of the switches (21-1, 21-2,...) Can be selected from a plurality of preset control modes according to the work situation, and the storage device 26 (mode storage) (Means) stores a plurality of control modes including a first control mode and a second control mode described below. Then, a control mode is selected from the plurality of control modes, and connection / disconnection of the power supply circuit is controlled based on the selected control mode.
[0028]
The mode is selected by inputting a mode selection command from the operation panel 29 provided on the operation panel 7 of the electronic component mounting apparatus 1. The CPU 25 reads the control mode selected from the storage device 26 in accordance with the input, and controls the interlock circuit 24 based on the selected control mode. Here, when the first control mode is selected, the circuit connecting / disconnecting device 21 is controlled in accordance with the device operation prohibition condition (here, the device operation is completely prohibited) set based on the request for ensuring safety, thereby The operation of each work module is uniformly prohibited.
[0029]
In a normal working state, the CPU 25 always controls the circuit connecting / disconnecting device 21 according to the first control mode unless a mode selection command is input from a specific worker. That is, when the door opening / closing detection switch 27 detects that the door 8 of the cover case 6 is opened, the interlock circuit 24 closes all the switches of the circuit connecting / disconnecting device 21. Thereby, the power supply to all work modules constituting the conductive adhesive pasting part 10, the mounting part 30, the first crimping part 40, the second crimping part 50, and the conveying part is cut off, and the operation of all the operation mechanisms is performed. Is stopped, and the safety of the worker who accesses the inside of the door 8 and performs the work is ensured.
[0030]
On the other hand, when the second control mode is selected, the circuit connecting / disconnecting device 21 is controlled in accordance with the operation permission condition for each work module set in advance and stored in the storage device 26, and the operation is permitted according to the operation permission condition for each work module. Operation of work modules other than the permitted operation module is prohibited. That is, when maintenance / adjustment work is performed for a certain work module, only work modules that are required to be allowed to operate in the work execution state can be operated, and other parts are prohibited from operating.
[0031]
For example, when the adjustment operation of the mounting operation of the mounting head is performed for the mounting unit 30, the operation of only the mounting mechanism 38 is permitted, and the operation of other work modules is prohibited. Note that FIG. 3 shows an example of work module division, and work module setting may be performed by further dividing the operation mechanism as necessary.
[0032]
The selection of the second control mode is performed by operating the operator identification switch 28 or by inputting a password given only to a specific worker through the operation panel 29. That is, the operator identifying switch 28, the operation panel 29, and the CPU 25 are mode selection means for selecting a control mode from a plurality of control modes, and the CPU 25 is connected to the circuit connecting / disconnecting device 21 based on the selected control mode. It becomes the control means which controls. Further, the operator identification switch 28, the operation panel 29, and the CPU 25 serve as identification means for identifying whether or not the worker is a specific worker set in advance.
[0033]
The operation permission condition for each work module may be stored in the storage device 26 with different setting contents for each individual specific worker. In this case, the storage device 26 is an operation permission condition storage unit that stores operation permission conditions for each work module with different setting contents for each specific worker.
[0034]
In this way, by setting the operation permission condition for each work module having different contents for each worker, when there are a plurality of the aforementioned specific workers, according to the contents of the adjustment work performed by each specific worker, Furthermore, operation permission conditions for each work module according to the skill level of each specific worker can be prepared in advance. Therefore, only when each specific worker accesses through the worker identification switch 28 or the operation panel 29, the working condition that balances good workability and necessary safety in performing the work can be obtained. Set automatically.
[0035]
In the above embodiment, an example in which the present invention is applied to an electronic component mounting apparatus for assembling a display panel has been described. However, an electronic component mounting apparatus configured by a plurality of work modules may be used for other types of apparatuses. The present invention may be applied.
