There is provided a control means for controlling movement positions and movement timings of a nozzle elevating means and a nozzle moving means. The control means stores positions and heights of obstacles located between a component supply unit and a circuit board in advance. The control means moves down a nozzle in sync with the time when the nozzle has finished passing over each obstacle after an electronic component has been photographed by a component camera. Alternatively, the control means moves the nozzle in a path to avoid the obstacles. In addition, in a component mounting region, the nozzle moves at a component mounting region movement height and the component is mounted by the nozzle moved down from the component mounting region movement height. Accordingly, it is possible to shorten an elevating stroke of the nozzle (). In addition, the nozzle can be elevated in an arc trajectory.

Component mounting method

An object of the present invention is to provide a component mounting apparatus and a component mounting method in which a movement time of a nozzle can be shortened so that production efficiency can be improved. There is provided a control means for controlling movement positions and movement timings of a nozzle elevating means and a nozzle moving means.

Device for mounting component

There are provided a positioning control method and a positioning control device, which enables high speed positioning with low power consumption without repeating two or more acceleration and deceleration operations during travel from an original position to a target position. There is also provided an electronic component mounting apparatus, which enables high speed positioning with low power consumption and enables mounting of electronic components in a short period of time. When a movable body is moved from the original position to the target position, there is set an operational passing position for avoiding a passing avoidance region, and driving of a drive unit having a smaller travel distance from the original position to a coordinate of the operational passing position is started later than driving start timing of a drive unit having a longer travel distance, from the original position to another coordinate of the operational passing position, by a specified period of time.

Positioning control method, positioning control device, and electronic component mounting apparatus using same

Disclosed are a component recognizing method and apparatus, and a component mounting method and apparatus, by which components with various heights held by a plurality of nozzles can be recognized continuously. The drive of a head is transmitted to nozzles, with surfaces to be recognized of components being controlled so as to be positioned in a recognizable range during respective recognizing operations of the components, and a continuous recognition is thereby made possible. The adjustment of heights of the surfaces to be recognized during the recognizing operations of the components is achieved by one drive unit and a plurality of drive transmitting units.

Component recognizing method and apparatus, and component mounting method and apparatus

In a motor drive device having a plurality of driver units for driving motors and a command generator for giving a command to the driver units which are connected in serial communication, there is a communication section for setting up the communication formats corresponding to each of the driver units having different communication formats including data transmission speed from one another. Communication among the plurality of driver units with the respective communication formats and the command generator is carried out on a single serial bus.

Motor drive, motor drive control method, and component attaching device

There are provided a positioning-controlling apparatus and a positioning-controlling method in which a rotary encoder ( ) detects the Z phase before the subject ( ) is return to the origin which is the position of the Z phase detected by the linear encoder ( ). The driving mode of the servo motor ( ) is switched from rectangular waveform pulse driving to sine waveform pulse driving upon the detection of the Z phase by the rotary encoder ( ). The subject's moving direction for returning to the origin may be previously specified, and in which the detection of the ON state of the origin sensor ( ), the detection of the Z phase by the rotary encoder ( ), and the detection of the Z phase by the linear encoder ( ) are done in this order, while the subject ( ) is being moved in the above specified direction. Alternatively, the rotary encoder ( ) may detect the CS phase instead of the Z phase.
