Description

One-dimensional transport path unit

The present invention relates to a one-dimensional conveyance path unit including a conveyance path for conveying a minute object, particularly a conveyance object such as a ceramic capacitor, in a one-dimensional direction.

In recent years, high performance and fine multilayer ceramic capacitors (MLCC) have been developed and used. This multilayer ceramic capacitor has a rectangular parallelepiped shape with a substantially square cross section. For example, the multilayer ceramic capacitor has a size of a short side of 0.5 mm and a long side of 1 mm, and a finer short side of 0.1 mm and a long side of 0.2 mm. Even things have been created. However, since it is a rectangular parallelepiped shape, it was not easy to convey. In addition, since it is fine and lightweight, it is difficult to stably hold, place, guide and the like, and it is not easy to carry each individual multilayer ceramic capacitor. Further, it is necessary to examine defects of each multilayer ceramic capacitor. However, it is not easy to inspect each surface of each multilayer ceramic capacitor for that purpose.

Therefore, an apparatus for inspecting four side surfaces of each multilayer ceramic capacitor while aligning and conveying a large number of multilayer ceramic capacitors has been proposed (for example, see Patent Document 1). In this inspection apparatus, a large number of objects are moved from a supply apparatus to a sloped space (substantially horizontal space), and then moved to a tunnel in a one-dimensional direction to inspect the side surface while being conveyed.

JP 2009-216698 A

In the inspection apparatus, the upper surface of the one-dimensional tunnel is constituted by the movable parts 111, 121, 131, 141 that can be removed, and the lower parts 112, 122, 132, 142 are constituted by the plurality of fasteners 113, 123, 133, 143. Is pressed against. For this reason, when the fastening force of the plurality of fasteners 113, 123, 133, 143 is unbalanced and in the portion where the fastening force of the fastener is not applied, the movable portions 111, 121, 131, 141 and the lower portion 112, The contact with 122, 132, 142 is not sufficient, and there is a possibility that the object is not smoothly moved by the air pulse in the tunnel formed between the two. This is presumably because the movable parts 111, 121, 131, 141 and the lower portions 112, 122, 132, 142 are not sufficiently in contact with each other, and a gap is generated, causing an air pulse to leak.

The object of the present invention is to improve the adhesion between the top plate constituting the upper surface of the conveyance path extending in the one-dimensional direction and the side surface of the conveyance path, to suppress air leakage, and to remove and attach the fasteners. It is to provide a one-dimensional transport path unit including an easy transport path.
