Embodiment approach 1

[0051] figure 1 It is a top view showing a configuration example of the conveyance system 2 of the present embodiment, figure 2 It is a functional block diagram showing an example of the connection relationship of the transport system 2 . Such as figure 1 As shown, the conveying system 2 of this embodiment includes a plate-shaped workpiece 11 for processing by a processing device (cutting device) 4 (see Figure 8 of (A), Figure 8 (B) etc.) the conveyance path 6 for conveyance.

[0052] The workpiece 11 is, for example, a disk-shaped wafer formed of a semiconductor material such as silicon. The front side of the workpiece 11 is divided into a plurality of small areas by a plurality of dividing lines (separation lanes) intersecting each other, and IC (Integrated Circuit, integrated circuit), MEMS (Micro Electro Mechanical Systems) are formed in each small area. , MEMS) and other devices.

[0053] A tape (dicing tape) 13 having a larger diameter than the workpiece 11 is a...

Embodiment approach 2

[0387] In this embodiment, the processing apparatus of the form different from the said embodiment is demonstrated. Figure 31 It is a perspective view showing the internal structure of the processing device (cutting device) 402 of this embodiment. In addition, in the following description, the same code|symbol is attached|subjected to the component common to the said embodiment, and detailed description is abbreviate|omitted.

[0388] The container 102 of the transport vehicle 10 is not placed on the lift table 404 of the processing device 402 . Instead, on the elevating table 404 of the processing device, the same two-stage cassette storage mechanism 24 (that is, the first cassette storage mechanism 24a and the second cassette storage mechanism 24b) as the loader / unloader 8 of the above-mentioned embodiment is provided. Two-stage cassette storage mechanism 406 (1st cassette storage mechanism 406a and 2nd cassette storage mechanism 406b).

[0389] That is, the cassette 30 i...

Abstract

The invention provides a transport vehicle, a transport path and a transport system, which can transport a processed object efficiently and safely. The transport vehicle travels on a transport path provided above a processing device and transports an object to be processed, the transport vehicle comprises: a frame to which wheels for traveling are mounted; a container for accommodating the object to be processed; a lifting unit which is provided on the frame and which lifts the container by suspending the container so that the container passes through an opening which vertically passes through the conveyance path; a power receiving terminal which is provided on the frame and receives power supplied from the outside; and a charging wiring that connects a secondary battery that supplies power to the lifting unit and the power receiving terminal, and that charges the secondary battery by supplying power received by the power receiving terminal to the secondary battery through the charging wiring when the container is passed through the opening by the lifting unit and lifts container by the lifting unit.

Description

technical field [0001] The present invention relates to a transport vehicle, a transport path, and a transport system used for transport of workpieces. Background technique [0002] In the manufacturing process of device chips incorporated in electronic equipment and the like, plate-shaped workpieces represented by semiconductor wafers and resin-encapsulated substrates are processed by various processing devices. When conveying a workpiece to this processing apparatus, a cassette capable of accommodating a plurality of workpieces is generally used. When the processing apparatus receives a cassette containing a plurality of workpieces, the workpieces are sequentially taken out from the cassette and processed. [0003] In order to improve the efficiency of processing a workpiece, a plurality of processing devices may be used in parallel. In this case, it is necessary to transport the workpiece to each of the plurality of processing devices at an appropriate timing. Therefor...
