Conveying device

Abstract

A conveying device comprises a body in which a power source and two scroll wheels of the same diameter and rotating synchronously are disposed. Each scroll wheel is wound with an elongated elastic extension plate having rigidity, and one end of each elastic extension plate extends out of the body. When in use, the power source is used to drive the two scroll wheel to rotate synchronously, so as to drive the elastic extension plates of the two scroll wheels to synchronously extend out of or retract in the body. When the ends of the two elastic extension plates extended out of the body are assembled with a clamp or a loading seat, thereby, the conveying operation can be carried out.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a conveying device, and more particularly to a conveying device which utilizes the synchronous movement of two elastic extension plates to offer the conveying function.[0003]2. Description of the Prior Art[0004]Regarding most of the automatic flows, no matter in the fabrication of semiconductor or in the fabrication and burning operation of the optical disc, the conveying step can not be omitted. Conventional conveying devices all utilize a platform which moves along a fixed rail to offer the conveying function. If focusing on the stability, two parallel rails are provided for the movement of the platform. However, the shortcoming of this conveying device is that its rails are positioned on the floor, so the conveying path also must be fixed according to the rails, and the conveying path cannot be changed flexibly.[0005]In addition, when the conveying device is not used, since the rails ...

AI Technical Summary

Benefits of technology

[0007]The primary objective of the present invention is to provide a conveying device. It utilizes two scroll wheels which are the same in diameter and rotate synchronously to scroll an elastic extension plate with rigidity to extend or retract, respectively. The two elastic extension plates extend or retract synchronously, in order to offer the conveying function when the two elastic extension plates are assembled with a loading seat or a clamp and the like. Thus achieving the objective that rails are not needed to preset.

[0012]at least one of the scroll wheels being driven by the power source; and two elongated elastic extension plates with rigidity, one end of each elastic extension plate being fixed on each scroll wheel, and each elastic extension plate being wound on each scroll wheel from inside to outside, the other end of each elastic extension plate extending out of the body through the gap of the body, each elastic extension plate is driven to extend or retract through rotation of each scroll wheel, thus carrying out a conveying operation.

[0022]A conveying method comprises the steps of: winding two elastic extension plates, from inside to outside, onto two parallel scroll wheels of the same diameter and rotating synchronously in opposite directions; positioning an object on the two elastic extension plates, rotating the two elastic extension plates and making the two elastic extension plates move synchronously and equidistantly; releasing the object after it is moved to a predefined position, to accomplish the conveying operation.

[0023]The advantages of the present invention are that: when the two scroll wheels are rotated in opposite directions by the power source, the two elastic extension plates will be driven to synchronously extend out of or retract in the body; and when the ends of the two elastic extension plates extended out of the body are assembled with a clamp or a loading seat, the conveying operation can be carried out; rails are not needed to preset, because of the two elastic extension plates which are used to perform the conveying operation; additionally, the conveying path can be changed by changing the extending or retracting direction of the two elastic extension plates.

Problems solved by technology

However, the shortcoming of this conveying device is that its rails are positioned on the floor, so the conveying path also must be fixed according to the rails, and the conveying path cannot be changed flexibly.

In addition, when the conveying device is not used, since the rails are positioned on the floor and cannot be disassembled freely, it will cause a spatial obstacle.
