[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work inspection apparatus for inspecting an end face of a hexahedral work, and more particularly to a work inspection apparatus capable of performing an end face inspection with high accuracy.

[0002]

2. Description of the Related Art There has been known a work inspecting apparatus for inspecting an electronic component (work) having a hexahedron shape, in which a work is inserted around the outer periphery of a disk and the work is inspected by an end face inspection unit. .

[0003] That is, the work inspection apparatus is provided on the outer periphery of a disk having a large number of concave portions for inserting and mounting the work, and is provided outside the disk, and performs an end surface inspection of the work inserted into the concave portion of the disk. And an end face inspection unit. in this case,
The disks are arranged in a horizontal direction, and fixed upper and lower plates are provided above and below the disks.

In the operation of the work inspecting apparatus, first, a work is inserted from a feeder into a concave portion formed on the outer periphery of a disk, and the work in the concave portion is sucked inward in a radial direction by vacuum.

[0005] Next, the disk is rotated, and three surfaces of the hexahedral work, that is, the outer surface in the radial direction, the upper surface, and the lower surface are inspected by the end surface inspection unit.

[0006]

As described above, in the conventional work inspection apparatus, only three end faces of the hexahedral work can be inspected. Also, the work is inserted into the recess provided on the outer periphery of the disc, but there is play between the inner surface of the recess and the work, so the position accuracy of the work in the recess is poor, and accurate end face inspection is required. Cannot do it.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a work inspecting apparatus capable of quickly and accurately inspecting six end faces of a hexahedral work.

[0008]

According to the present invention, there is provided a first disk having a plurality of first concave portions formed on an outer periphery for gripping a hexahedral work, and the first disk is disposed orthogonal to the first disk. A second disk having a plurality of second recesses formed on an outer periphery thereof for receiving and gripping the work in the first recess, and a first end surface inspection unit provided outside the first disk to inspect three surfaces of the work. And a second end surface inspection unit provided outside the second disk and inspecting the remaining three surfaces of the work, wherein the first recess and the second recess are openable and closable. This is a work inspection device.

According to the present invention, the work gripped in the first concave portion of the first disk is inspected on its three surfaces by the first end surface inspection section, and then transferred to the second concave portion of the second disk. It is. The remaining three surfaces of the workpiece held by the second concave portion of the second disk are inspected by the second end surface inspection unit.
