[0020]

SUMMARY OF THE INVENTION The present invention has completed a standing apparatus for an object to be processed in order to solve the above problems. The apparatus for standing up an object to be processed of the present invention includes a mounting table having a suction hole in a contact surface with the object to be processed on which the object to be processed is mounted, and the contact surface of the mounting table from a substantially horizontal state to a substantially vertical state. And a support base that rotatably supports the mounting table, and the mounting table includes:
It is characterized in that the suction hole is provided with an opening which is communicated in a sealed manner.

That is, the object to be processed is brought into close contact with the opening by sucking the air inside the mounting table from the opening provided in the mounting table. In the close contact state, the contact surface of the mounting table with the object to be processed is changed from the substantially horizontal state to the substantially vertical state,
The object to be processed stands up by rotating the mounting table.

Since the suction pressure is uniformly applied to the object to be processed through the plurality of suction holes, a large stress is not locally applied to the object to be processed. Therefore, even a soft object to be processed will not crack.

Further, since the suction method is used, there is no positional deviation due to the impact at the time of clamping unlike the clamping method, and further,
Even if the object to be processed is not standing upright in the vertical direction, it is possible to prevent the object from falling due to its own weight, so that the object to be processed can be reliably stood upright.

Further, since the object to be processed is erected by suction so that the object to be processed is different in size, a suction hole is provided according to the size, so that the size of the object to be processed is not limited.

Further, the standing device itself has a simple mechanism for sucking and rotating the object to be processed and has a small number of driving means, so that it can be manufactured in a compact size.

Further, in the apparatus for raising the object to be treated of the present invention, it is preferable that the suction holes are arranged in a staggered pattern.

This is because even if the intervals between the objects to be processed are different, the objects to be processed can be surely sucked, and there is no displacement from there, so there is no adsorption error and any object to be processed can be absorbed. This is because it can respond.

Further, in the apparatus for raising the object to be treated of the present invention, it is preferable that the contact surface is provided with a step.

This is because the object to be processed is fixed by this step, so that the posture at the time of rotation or standing up is stable even if the suction force from the suction hole is very small.
