Embodiment Construction

[0062]figure 1 It is a diagram showing an embodiment of the present invention. More specifically,figure 1 (A) is a diagram showing the appearance of the first embodiment of the conductive device of the present invention. In addition,figure 1 (B) is a diagram showing the appearance of a part of a roller conveying device equipped with the conductive device. Such asfigure 1 As shown in (a), the conductive device 1 has a structure in which a shaft member 40 is protrudingly provided on the central axis of a substantially cylindrical housing 100.

[0063]The shaft member 40 is free to rotate with respect to the housing 100 around a rotation axis substantially coincident with the central axis of the housing 100. The front end of the shaft member 40 protruding from the housing 100 to the outside is connected to a ground wire 70 via a terminal fitting 71. At the end of the housing 100 on the side opposite to the side where the shaft member 40 is provided, a male screw 11 is formed coaxially wit...

Abstract

The invention provides a structure which is easy to assemble in a conductive device and a roller conveying device which are installed on a roller shaft for the purpose of electrical grounding. This conductive device is provided with: a housing (100) having an engagement section (11) that engages with the end of a roll shaft; a shaft member (40) which is formed of a conductive material and protrudes from the inside of the housing to the outside through an opening provided in the housing; a bearing (50) that rotatably supports the shaft member with respect to the housing within the housing; andconductive parts (20, 30) which elastically abut against the shaft member and electrically connect the shaft member and the housing. The housing includes: a body portion (10) having an internal spacecapable of accommodating the bearing and the conductive portion; and a cover portion (60) which is engaged with the body part to block the internal space, thereby sealing the bearing and the conductive part in the internal space. The body portion and the cover portion are integrated by being screwed to each other to form a housing.

Description

Technical field[0001]The present invention relates to a conductive device for electrically grounding a roller shaft of a roller conveying device and a roller conveying device including the conductive device.Background technique[0002]For example, in the process of processing various substrates such as a glass substrate for a display device or an electronic circuit substrate to manufacture an element, the substrate is usually conveyed by a roller conveyor. The rotation of the roller shaft of the roller conveying device or the friction between the roller and the substrate generates static electricity, which may cause deterioration or damage to the substrate or the components formed on the substrate. As a solution to this problem, it is conceivable to provide an ionizer for eliminating static electricity in the conveyance path of the substrate, or to electrically ground the roller shaft, for example.[0003]For example, the technology described in Patent Document 1 relates to a grounding ...
