Abstract

There is provided a carrier device that has a linkage arm mechanism, in particular, a carrier device that cools the linkage arm mechanism and can reduce the impact of radiation heat from a work that is in a high temperature state. A carrier device is a carrier device that includes a linkage arm mechanism and a pivot shaft, and the linkage arm mechanism includes lower arms and upper arms, and one ends of which are respectively connected to the lower arms, and horizontal movement members that support a work that is connected to the other ends of the upper arms, and cooling plates are respectively arranged between the upper arms, and the horizontal movement members.

First claim

The invention claimed is:

1. A carrier device comprising:
a linkage arm mechanism that is used to carry a work in a vacuum space; and
a pivot shaft that pivotally supports the linkage arm mechanism so that the linkage arm mechanism can rotate around a vertical shaft,
wherein the linkage arm mechanism comprises lower arms, upper arms one ends of which are respectively connected to the lower arms, and horizontal movement members that support the work that is connected to the other ends of the upper arms, and cooling plates are respectively provided between the upper arms and the horizontal movement members, and
wherein the cooling plates includes an all movement range of the upper arm in the planar view, and reflective materials are stuck on surfaces of the cooling plates on the horizontal movement member side; and
wherein a pivot shaft cooling plate is wound around the pivot shaft.

2. A carrier device comprising:
a linkage arm mechanism that is used to carry a work in a vacuum space; and
a pivot shaft that pivotally supports the linkage arm mechanism so that the linkage arm mechanism can rotate around a vertical shaft,
wherein the linkage arm mechanism comprises lower arms, upper arms one ends of which are respectively connected to the lower arms, and horizontal movement members that support the work that is connected to the other ends of the upper arms, and cooling plates are respectively provided between the upper arms and the horizontal movement members, and
wherein the cooling plates includes an all movement range of the upper arm in the planar view, and reflective materials are stuck on surfaces of the cooling plates on the horizontal movement member side;
the cooling plates are provided on lower sides of the lower arms;
and wherein a pivot shaft cooling plate is wound around the pivot shaft.
