Problems solved by technology

[0005] In the non-contact power feeding device described in Patent Document 1, the impedance of the power receiving side is estimated from the power transmitting side, so this impedance includes errors, and the transfer efficiency of non-contact power feeding cannot be sufficiently improved.
In addition, in the contactless power supply device described in Patent Document 2, a plurality of feeders (cassettes) accommodating components are mounted on the component supply unit, and the load impedance of the component supply unit changes depending on the number of feeders. Since it does not respond to changes in load impedance, the transmission efficiency of non-contact power supply may drop

Embodiment Construction

[0022] Hereinafter, the case where the embodiment of the contactless power supply device of the present invention is applied to a component mounting device will be described with reference to the drawings. Such as figure 1 As shown, the component mounting device is roughly composed of a board transfer device 10 , a component supply device 20 and a component transfer device 30 . In addition, in figure 1 Herein, the conveyance direction of the substrate is defined as the X-axis direction, the horizontal direction perpendicular to the X-axis direction is defined as the Y-axis direction, and the vertical direction perpendicular to the Y-axis direction is defined as the Z-axis direction.

[0023] The substrate transfer device 10 is a so-called double-conveyor type substrate transfer device in which a first transfer device 11 and a second transfer device 12 for transferring a substrate in the X-axis direction are arranged in two rows. The first conveying device 11 and the second c...

Abstract

The invention provides a non-contact power supply device capable of providing power in a non-contact manner and high in transmission efficiency, wherein the sending-side impedance is accurately adjusted by an impedance adjustment part (56) to be equal to both the load impedance of a lifting circuit used for driving the nozzle support part (43) of a currently installed element pickup head (32) to move up and down, and the load impedance of an electro-spinner with an R-axis servo motor (47) and used for driving the nozzle support part (43) to rotate. In this way, the transmission efficiency of the non-contact power supply for the element pickup head (32) is improved. In addition, since no impedance measuring circuit is adopted, the non-contact power supply device is low in cost and small in size.

Description

technical field [0001] The present invention relates to a non-contact power supply device capable of supplying electric power in a non-contact manner. Background technique [0002] For example, Patent Documents 1 and 2 disclose contactless power supply devices capable of supplying electric power in a contactless manner. The contactless power supply device described in Patent Document 1 performs power supply control based on the frequency characteristic of impedance that changes according to the distance between the power transmission resonator and the power reception resonator. That is, the impedance of the power receiving side is estimated from the power transmitting side, thereby improving the transmission efficiency of the contactless power feeding. In addition, the non-contact power supply device described in Patent Document 2 supplies power in a non-contact manner to the servo motor that rotates the nut mounted on the table of the component supply unit, and the table i...
