Abstract
A fixture and a method for handling stacking objects which can improve automation degree of handling stacking objects. The fixture for handling stacking objects includes a frame; a first carriage which has a first upper arm; a second carriage which has a second upper arm; and a first actuator configured to synchronously move the first carriage and the second carriage in the first direction between a first position at which the first upper arm and the second upper arm to clamp a first object from two opposite sides of the first object.
Claims19
A fixture for handling stacking objects, comprising:
- a frame;
- a first carriage arranged on the frame and comprising a first upper arm;
- a second carriage arranged on the frame in parallel with the first carriage at a position different from the first carriage in a first direction and comprising a second upper arm;
- a first actuator attached to the frame and configured to synchronously move the first carriage and the second carriage in the first direction between a first position at which the first upper arm and the second upper arm are close to each other to clamp a first object from two opposite sides of the first object and a second position at which the first upper arm and the second upper arm are far away from each other to release the first object;
- a third carriage arranged on the frame in parallel with the first carriage at a position different from the first carriage in the second direction and comprising a first lower arm;
- a fourth carriage arranged on the frame in parallel with the third carriage at a position different from the third carriage in the first direction and comprising a second lower arm;
- and
- a second actuator attached to the frame and configured to synchronously move the third carriage and the fourth carriage in the second direction between a third position at which the first lower arm and the second lower arm are close to each other to clamp a second object from two opposite sides of the second object and a fourth position at which the first lower arm and the second lower arm are far away from each other to release the second object.
