Abstract

PROBLEM TO BE SOLVED: To prevent scattering of dust and play in drive parts. SOLUTION: A movable plate 28 is disposed over a baseplate 14 via a translatory guide 16 so as to be moved in a first direction by a motor 30. The movable plate 28 has, over its center, an opening/closing plate 46 disposed via a second translatory guide 44, and over its front end, two gripper arms 50 and 52 disposed via a third translatory guide 48. Forward movement of the opening/closing plate 46 by an electromagnetic solenoid 54 forces gripper rollers 56 and 58 on the movable plate 28 into acting on oblique lines 50c and 52c of the gripper arms 50 and 52 or opening the gripper arms 50 and 52.

And the male screw member 38
A pulley 40 is attached to one end of the motor 30, and the rotating shaft 30 a of the motor 30 and the pulley 40 are connected via a belt 42. Accordingly, when the motor 30 is driven, the male screw member 38 is rotated with the rotation, the female screw member 34 screwed to the male screw member 38 is moved in the first direction, and the movable plate 28 is accordingly moved in the first direction. Be moved. The moving distance and moving direction of the movable plate 28 are changed by switching the number of rotations and the rotating direction of the motor 30.

An opening / closing plate 46 is provided at the center of the upper surface of the movable plate 28 via a second linear motion guide 44 extending in the first direction, and the front end of the upper surface is orthogonal to the first direction. Two gripper arms 50 and 52 are provided via a third linear guide 48 extending in the second direction, and an electromagnetic solenoid 54 as an electric driving means is provided at the rear end of the upper surface.

4 is fixed to the piston 60 by a screw 62.

The gripper arm 50 is formed in a substantially L shape in plan view having a long side 50a extending in the second direction and a short side 50b protruding forward from one end of the long side 50a.
The gripper arm 52 is formed in a substantially L shape in plan view including a long side 52a extending in the second direction and a short side 52b protruding forward from one end of the long side 52a.
Opposite sides (hereinafter, referred to as “inclined sides”) 50c and 52c of “a” are inclined with respect to the first direction so as to have a substantially C shape. Further, support portions 64 and 66 are formed to rise vertically from the front ends of the short sides 50b and 52b, and gripper rollers 68 for holding the disk 12 are provided at lower and upper portions of the support portions 64 and 66, respectively. Further, on the upper surfaces of the gripper arms 50 and 52, a coil spring 70 for connecting them is provided.
By the bias of the coil spring 70, the inclined sides 50c and 52c are brought into contact with the opening / closing rollers 56 and 58. Therefore, the opening / closing plate 46 is controlled by the electromagnetic solenoid 54.
When is moved forward, the gripper arms 50 and 52 are opened, and when moved backward, they are closed.

A cover 72 is mounted on the base plate 14 so as to cover the whole.

The clamp device 10 is, for example, a disk 1
2 is used to attach to or detach from the spindle hub of the disk manufacturing apparatus. Hereinafter, the operation of removing the disk 12 from the spindle hub will be briefly described. First, the clamp device 10 is positioned at a position facing the disk 12 by a robot arm (not shown) or the like. Then, the motor 30 is driven to move the movable plate 28 forward, and the gripper arms 50 and 52 are positioned in the first direction. Subsequently, the opening / closing plate 46 is retracted by the electromagnetic solenoid 54, and the disk 12 is nipped by the gripper roller 68 using the restoring force of the coil spring 70. Thereafter, the motor 30 is driven to move the gripper arm 5 together with the movable plate 28.
