There are provided an air-conditioning device that can easily perform fan setting to obtain a proper air volume in accordance with external static pressure, and a method of controlling the air-conditioning device. There is executed air volume setting processing (Sto S) for measuring an actual rotation number (r_MAX) when a fan motor for driving an air blowing fan is set to a maximum output, and setting the rotation number corresponding to a target air volume of the air blowing fan under normal operation of the built-in type air-conditioning device.

Air-conditioning device and method for controlling air-conditioning device

An electronic component mounting apparatus includes two second linear-motion devices on each of which an image pickup device and a mounting head are placed so as to be movable in an X direction, a first linear-motion device for moving the second linear-motion devices in a Y direction independently of each other, in which the image pickup device is placed at such a position as to be contained within an X-directional width of the mounting head and moreover contained within a Y-directional total width of the mounting head and the second linear-motion device. Thus, since the image pickup region of the camera is contained within the moving region of the mounting head, there is no need for ensuring a moving distance taking into account only the camera's image pickup region, so that the moving-axis length of the second linear-motion devices can be reduced.

Moving device and electronic component mounting

For implementing a method of mounting electronic components, and an apparatus therefor, which has a much reduced tact time, the nozzlesandare kept in holesprovided in a straight line row in nozzle stockerin the order of use sequence. When the type of electronic components to be mounted on a circuit board changes, transfer headhas to go to a place above the nozzle stockerto replace the nozzle. In the invented mounting method, and mounting apparatus, the transfer headis required to move only to a place above the next nozzleafter returning the used nozzleto a hole. Thus the stroke L of transfer headneeded for the nozzle exchange is significantly reduced, and the nozzle may be replaced within a short time.

A tray feeder sequentially takes pallets, each holding a tray storing electronic parts, out of a magazine and feeds them to a pick-up position where the electronic parts are picked up by a transfer head of an electronic parts-mounting apparatus. The tray feeder comprises the magazines for containing the pallets in a stacked manner, a drawing portion for drawing the pallet from the magazine and carrying the same thereon, a lifting-lowering portion for vertically moving the drawing portion, a non-mounted-parts discharge portion provided above the magazines, and a replenishing portion for receiving the pallet, holding the empty tray from which the electronic parts have been picked up, and for recharging the pallet after fresh electronic parts are replenished. With this construction, there can be achieved the tray feeder that is excellent in the operation efficiency and is compact in size.

Electronic parts-feeding tray feeder and electronic parts-feeding method

Trays within a tray feeder provided with electronic components requiring a higher accuracy of mounting position such as QFPs, etc. are collectively placed at one side of a recognition device equipped with a line sensor. A transfer head picks up an electronic component in the tray and discerns a position of the electronic component by moving over the line sensor in one and the same fixed direction at all the time. This scanning direction is the same as a direction of calibration of a nozzle of the transfer head. Accordingly, a detecting error in the position of electronic component caused by the scanning direction is eliminated and the electronic component can be mounted with a high positional accuracy on a substrate.
