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.
Claims9
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 includes a first linkage arm mechanism and a second linkage arm mechanism,
- wherein the first linkage arm mechanism comprises first lower arm, first upper arm one end of which is connected to the first lower arm, and first horizontal movement member that supports the work that is connected to the other end of the first upper arm,
- wherein a first cooling plate which is fixed so as to be rotated with the rotation of the pivot shaft is provided between the first upper arm and the first horizontal movement member, and separated from the first upper arm and the first horizontal movement member and,
- wherein the first cooling plate comprises a passing groove so as to pass a connecting means between the first upper arm and the first horizontal movement member when the first linkage arm mechanism is moved,
- wherein the second linkage arm mechanism comprises second lower arm, second upper arm one end of which is connected to the second lower arm, and second horizontal movement member that supports the work that is connected to the other end of the second upper arm,
- wherein a second cooling plate which is fixed so as to be rotated with the rotation of the pivot shaft is provided between the second upper arm and the second horizontal movement member, and separated from the second upper arm and the second horizontal movement member and,
- wherein the second cooling plate comprises a passing groove so as to pass a connecting means between the second upper arm and the second horizontal movement member when the second linkage arm mechanism is moved.
