Embodiment Construction

[0032] Before describing the embodiment, a general conventional linear motor device 9 will be described first. Figure 5 It is an explanatory drawing schematically explaining the structure of the conventional linear motor apparatus 9. The linear motor device 9 is constituted by a rail 91 , a moving body 92 , a plurality of magnets 93 , a plurality of coils 94 , a power supply cable 95 , and the like.

[0033] The rail 91 is a rail member extending along the moving direction of the moving body 92 . track 91 in Figure 5 , extending from the left front side to the right inner side along the moving direction M shown by the hollow arrow. The bottom plate 911 and the two side plates 912 and 913 are integrated to form the rail 91 . The cross-sectional shape of the rail 91 perpendicular to the moving direction is a groove shape opening upward. The moving body 92 has a substantially box shape and is mounted on the rail 91 so as to be movable. The mobile body 92 is attached to the...

Abstract

The present invention is a non-contact power supply device that supplies power to the coil of a linear motor device in a non-contact manner. The linear motor device includes a rail member, a moving body mounted on the rail member, and a plurality of A magnet and a coil provided on the moving body. The non-contact power supply device includes: two sets of non-contact power supply parts respectively having a power supply electrode plate extending in the moving direction of the track member and a power supply electrode plate provided on the mobile body and connected to the power supply electrode plate. The power receiving electrode plates facing each other can perform non-contact supply of high-frequency power; the high-frequency power supply unit supplies high-frequency power between the power supply electrode plates; High-frequency power from the electrode plates is converted and fed to the coil. Therefore, it is possible to provide a low-cost non-contact power supply device capable of non-contact power supply to the coil of the moving body side of the linear motor device with a large power supply capacity and high power supply efficiency, and the non-contact power supply does not affect the propulsion force. produce.

Description

technical field [0001] The present invention relates to a non-contact power supply device, and more specifically, to a device for supplying power to a coil provided on a moving body of a linear motor device in a non-contact manner. Background technique [0002] There are solder printing machines, component mounting machines, reflow soldering machines, board inspection machines, etc. as board working equipment for producing boards on which many components are mounted. Many of these machines are connected by a board transfer device to form a board production line. Many of these substrate working equipment generally include a moving body that moves on the substrate to perform predetermined operations, and the moving body is driven by a linear motor device, a ball screw mechanism, or the like. Furthermore, in order to supply required electric power to the moving body, conventionally, a deformable power supply cable is used, or a sliding power supply unit capable of supplying pow...
