Abstract

PROBLEM TO BE SOLVED: To provide a tray type cassette capable of coping with scaleup of or super-scaleup of a base plate on the basis of a mechanism different from a method of supporting a base plate such as a glass base plate by rib-like shelf pieces of grooved side plates. SOLUTION: This lattice-like tray type cassette has a basic structure comprising peripheral frames 1 forming a rectangular skelton and cross supports 2 provided among the peripheral frames 1. A main frame is composed of a left- hand peripheral frame 1L, a right-hand peripheral frame 1R and a rear peripheral frame 1B of the peripheral frames 1. A sub-frame is formed with a front peripheral frame 1F of the peripheral frames 1 and the cross supports 2. The main frame is provided with extension members 3 extending from an inside face of the main frame, or from a bottom face of the main frame, toward a position lower than an upper face of the main frame. Resin pins 4 for supporting a base plate G from below are protrusively provided on the extension members 3 attached to the main frame and on the sub-frame, respectively. Further, the main frame is formed into an insertable engagement structure which makes the stack of trays possible. A bottom plate can also be provided at the bottom of a lattice-like tray.

2. Description of the Related Art As a substrate cassette for accommodating substrates such as glass substrates separately so as not to contact each other, a pair of opposing side surfaces of a box-shaped frame are formed by grooved side plates. The thing which can make a substrate enter and exit and accommodate between the corresponding grooves of the grooved side plate is widespread. There are various shapes and designs of the grooved side plates, but basically all of them have a number of rib-shaped shelf pieces projecting in parallel from the back of the side plate at a predetermined pitch toward the inside of the cassette. It has a different shape. A gap between adjacent rib-shaped shelf pieces becomes a groove, into which a substrate enters and leaves and is accommodated.

However, when the size of the glass substrate is increased, even if the glass substrate is a rigid glass substrate, its bending becomes excessive. If the pitch between the pieces is not considerably large, the glass substrate cannot be smoothly moved in and out, and the number of glass substrates that can be accommodated in one cassette is reduced.

In the above description, a trayless cassette composed of only a lattice is described. However, it is preferable to provide a bottom plate (5) at the bottom of the lattice-shaped tray.
When the bottom plate (5) is provided, even if abrasion dust is generated due to friction between the upper end of the resin pin (4) and the back surface of the board (G), the dust may fall on the upper surface of the lower board (G). This is because it is prevented. The bottom plate (5) may be provided so that its upper surface is flush with the back surface of the bar (2), or its upper surface may be provided at a position slightly below the back surface of the bar (2). If the bottom plate (5) is provided, it has a disadvantageous effect on weight and cost as compared with the case where the bottom plate (5) is not provided.Therefore, a tray cassette without the bottom plate (5) or a bottom plate (5 5) Tray cassette with

The resin pins (4) are made of a dust-preventing resin (for example, polyetheretherketone, polyimide, polyetherimide, polyacetal, polyamide, ultra-high-density resin), which hardly generates dust even by friction with the substrate (G). It is desirable to use a molded article of high molecular weight polyethylene, polytetrafluoroethylene, various elastomers, etc.), and at that time, molding is performed using a natural product substantially not containing a filler.

The left peripheral frame (1L) and the right peripheral frame (1R) of the main frame have a projecting member (3) projecting from the inner surface of the main frame at a position lower than the upper surface thereof toward the inside of the cassette. 4 each horizontally
Individually mounted (see FIG. 1). A resin pin (4) is provided on the upper surface of each of the projecting members (3) (see FIG. 2). Also, the same resin pins (4) protrude on the upper surface of the crosspiece (2) installed between the front peripheral frame (1F) and the rear peripheral frame (1B) among the sub-frames. These 12 resin pins
The upper end of (4) is on the same plane at a position lower than the plane formed on the upper surface of the main frame, and when the upper end of the resin pin (4) interferes with the glass substrate (G), The positional relationship is such that the upper surface does not protrude above the upper surface of the main frame.
The resin pin (4) is obtained, for example, by injection molding a natural product of polyetheretherketone, polyetherimide or an elastomer.

As described in the operation section, in the tray cassette of the present invention, a mechanism different from the conventional system in which a substrate such as a glass substrate is supported by a rib-shaped shelf of a grooved side plate. Based on the above, a tray-shaped cassette in a lattice shape is used. Then, the board (G) is placed on the projecting member (3) attached to the main frame and the resin pin (4) projecting from the sub-frame, and the resin pin
The board (G) is supported from below at the upper end of (4). Therefore, even when the substrate (G) is large or very large, the substrate (G) is securely supported with almost no bending,
Substrate (G) by robot hand (fork) (6)
It does not cause any trouble in or out of the building. When the bottom plate (5) is provided on the bottom of the grid-shaped tray, the upper end of the resin pin (4) and the board
Even if abrasion dust is generated due to friction with the back surface of (G), the dust is prevented from dropping on the upper surface of the lower substrate (G). Increase the overhang length of the overhang member (3),
When the resin pin (4) protrudes from the free end side, the amount of deflection of the substrate (G) is further reduced.
