Transferring device

Abstract

The invention relates to a transferring device, which includs a transferring rail with a fork part forking to the first direction and the second direction, a transport vehicle moving along the transferring rail, the device is characterized in that it includes a first direction magnetic guidance part set on the one side of the fork part for guiding the transport vehicle moving to the first direction; a second direction magnetic guidance part set on the other side of the fork part for guiding the transport vehicle moving to the second direction; a pair of magnetic induction guidance plates set on the lateral face of the transport vehicle and corresponding to the first direction magnetic guidance part and the second direction magnetic guidance part, the moving path of the fork part of the transport vehicle is guided by magnetising certain one switching on voltage of the first direction magnetic guidance part and the second direction magnetic guidance part. Hereby, the moving path of the transport vehicle is changed rapidity and steadily on the fork part of the transport vehicle.

Description

technical field [0001] The invention relates to a conveying device, in particular to a conveying device which enables a transport vehicle to move quickly and stably along a conveying guide rail through an improved structure. Background technique [0002] In general, conveyors are devices used to automatically transport raw materials and products between processes in the manufacturing process of semiconductors, LCDs, and TFTs. Recently, technology is being developed that can reduce the branching time of the conveying device at the branching part of the conveying rail, so that the conveying device can transport raw materials and products at high speed to improve the production capacity of products. [0003] The branching method of the conveying rail adopted by the existing conveying device is a mechanical method using a rail guide and a turn table, and there is a problem that the branching time is long when the mechanical method is adopted. In order to overcome the shortcomin...

Problems solved by technology

[0007] However, when a large gravitational force is generated to drive the transport vehicle, if the rigidity of the structure on which the permanent magnet is installed on the transport vehicle is not large enough, the structure will sag, and it is difficult to maintain the magnetic force between the coil and the permanent magnet. a certain distance

[0008] In addition, the conventional transmission device has the potential that the magnetic field of the electromagnet installed at the branch may affect the magnetic field generated in the linear motor.

That is, for the guide rail of the branch part, since the coil for driving the linear motor and the electromagnet for selectively turning on the voltage in order to change the path are installed on the same guide rail, the magnetic field of the electromagnet may affect the magnetic field of the coil, This leads to problems with the control of linear motors

[0009] Moreover, the existing transmission device constrains and guides the transport vehicle through the magnetic force on the entire guide rail, so the use of permanent magnets and electromagnets is increased, so the installation cost of the entire transmission device is increased.
