DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0008]
FIG. 1 is an external view of an electronic component mounting machine.
[0009]
The electronic component mounting machine of FIG. 1 includes a conveyor 32 that transports a substrate 31 on which an electronic component is mounted to a position where the electronic component is mounted, a component supply cartridge 33, a rotary head 34 that mounts the electronic component on the substrate 31, An alignment servo motor 35 that moves the substrate 31 to the mounting point of the rotary head 34 is provided.
[0010]
When mounting electronic components, the substrate 31 is first transported to the mounting position of the electronic components by being placed on the conveyor 32. At the same time, the rotary head 34 receives the electronic component from the component supply cartridge 33 and moves to the mounting position of the electronic component. The alignment servo motor 35 moves the substrate 31 to the mounting point of the rotary head 34, and the rotary head 34 mounts an electronic component on the substrate 31. Thereafter, the positioning servo motor 35 and the rotary head 34 are repeatedly mounted with electronic components while being synchronized.
[0011]
FIG. 2 is a block diagram showing a configuration of a simulation apparatus for simulating the electronic component mounting machine of FIG. The simulation apparatus includes a controller 41 that controls the electronic component mounting machine, a simulation apparatus 42 that evaluates the controller 41 instead of the actual electronic component mounting machine when the controller 41 is developed, and an operating characteristic parameter that is included in the simulation apparatus 42. And an operation characteristic parameter setting unit 47 for outputting 48.
[0012]
The simulation device 42 is composed of a parallel processing computer, and is composed of processors 43 to 46. The processor 43 simulates the operation of the conveyor 32 of FIG. 1, the processor 44 simulates the operation of the component supply cartridge 33, the processor 45 simulates the operation of the rotary head 34, and the processor 46 is the alignment servomotor 35. Simulate the behavior of. Each of the processors 43 to 46 is processed for each predetermined calculation cycle, and has a data group including an identification number, an elapsed time, and a control target device state (on / off). The operation characteristic parameter setting unit 47 sets an operation characteristic parameter 48 that is a parameter for determining operation characteristics such as the operation time of the conveyor 32, the component supply cartridge 33, the rotary head 34, and the alignment servo motor 35, the installed position, and the like. It outputs to the processors 43-46.
[0013]
Next, the operation of this embodiment will be described with reference to FIG. First, the operation characteristic parameter setting unit 47 outputs the operation characteristic parameters 48 of the conveyor 32, the component supply cartridge 33, the rotary head 34, and the positioning servo motor 35, which are devices to be controlled, to the processors 43 to 46, respectively. In the processors 43 to 46, the operation characteristics of each control target device to be simulated are set by inputting the operation characteristic parameter 48. When the simulation is started and the controller 41 issues an operation command to each of the processors 43 to 46, each of the processors 43 to 46 changes its state based on the received operation command, the elapsed time included therein, and the set operation characteristic parameter. It is determined whether to perform the determination, and the determination result is transmitted to the controller 41. This operation is repeated to simulate the electronic component mounting machine.

In this embodiment, since the operation of each part of the electronic component mounting machine is independently simulated by each processor of the parallel processing computer, the operation of each part of the electronic component mounting machine can be simulated with a simple program. . Further, since the response time to the controller 41 does not change even if the number of control target parts to be simulated, that is, the number of processors of the simulation device 42 is increased, the number of parts of the electronic component mounting machine that can be simulated is not limited. .
