Abstract:
1. A component mounting apparatus comprising: a first board transfer device for loading and unloading first boards with a first component mounting position; a second board transfer device for loading and unloading second boards with a second component mounting position; a component supply device for supplying components of plural kinds to be mounted on the first boards and the second boards; a component placing device including a component placing head for picking up the components from the component supply device to mount the components on the first and second boards, and a head moving mechanism for moving the component placing head in at least two directions parallel to surfaces of the first and second boards; and a controller for controlling operations of the first and second board transfer devices, the component supply device, and the component placing device; wherein the controller is configured to control the component placing device to mount the components on the first boards and the second boards at a rate of M-sheets to N-sheets, where M-sheets is a first number of the first boards and N-sheets is a second number of the second boards to be mounted during a mounting period and where M-sheets is not equal to N-sheets, by performing loading and unloading of the first boards by the first board transfer device with the first component mounting position and loading and unloading of the second boards by the second board transfer device with the second component mounting position, and wherein the controller is configured to operate, when one of the first and second board transfer devices is performing the unloading and loading of the boards with an associated one of the first and second component mounting positions, the component placing device to mount components on the other of the first or second board loaded by the other of the first and second board transfer devices to the other of the first and second component mounting positions and to execute an M-sheets to N-sheets rate mounting control to operate the first and second board transfer devices and the component placing device so that while the component placing device mounts the components on the first boards of the M-sheets at the first component mounting position, the component placing device mounts the components on the second boards of the N-sheets at the second component mounting position during the mounting period.
