The present invention relates to a carrier for wafer boxes, and more particularly to an anti-shock carrier for wafer boxes.
BACKGROUND OF THE INVENTIONIn general, there are two types of 12-inch front opening wafer boxes. One is the front opening unified pod (FOUP) for the pre-processing of the semiconductor fabrication, and the other is the front opening shipping box (FOSB) for the post processing of the semiconductor fabrication, such as the testing and packaging etc. The front opening unified pod (FOUP) is applied to the indoor transportation during the pre-processing, and the wafers usually suffer less damages. However, the front opening shipping box (FOSB) is applied to the outdoor transportation, and during the outdoor transportation the wafers often suffer some damages.
During the outdoor transportation, the FOSB is usually put on a hand-operated cart. Even though the hand-operated cart is equipped with a shock absorber, the anti-shock effect is poor. Please refer to
Usually the wafer boxes are packaged in a black or gray vacuum bag for being transferred to the post processing of the semiconductor fabrication. According to such a package fashion, it is not easy to point out when and how the wafers are broken.
Therefore, how to provide the carrier with anti-shock effects in both horizontal and vertical directions and how to monitor the wafer boxes during the transportation have become the major problems waiting to be solved in the industry. In order to overcome the drawbacks in the prior art, a carrier for wafer boxes is provided. In the particular invention, the problems of poor anti-shock effect in horizontal direction and the rough transportation are solved and it is also safe and convenient to stabilize the wafer boxes in a carrier.

Preferably, the cover device includes a first and a second covering components so as to cover at least one wafer box, and the cover device is a transparent cover with a canary yellow color.
Preferably, the wafer box is a front opening shipping box (FOSB), and the first covering component includes a clip portion for clipping the second covering component.
Preferably, a first and a second covering shafts are arranged respectively on the first and the second covering components so as to rotate the first and the second covering components to a first and a second open positions.
Preferably, the second covering component includes a connecting plate connected to the second cover shaft, and the second open position is a horizontal position.
Preferably, the first and the second covering components respectively have a first and a second handles for opening the first and the second covering components.
Preferably, the first covering component has a pneumatic bar for propping the first covering component.
Preferably, the carrier main body has a second receiving room for placing the second covering component therein.
Preferably, the carrier main body has a movable partition for facilitating the wafer boxes being placed into the carrier main body.
Preferably, the carrier main body has a rod for pushing the carrier main body, and the first and the second covering components are anti-electrostatically processed.
Preferably, the shock absorbing device has a rolling wheel, and the oblique shock absorber is arranged between a first positioning shaft and the rolling wheel, and the first positioning shaft is a first rotating axle for the oblique shock absorber.
Preferably, the shock absorbing device has a fixing base and two rotating plates, the two rotating plates are arranged between the fixing base and the rotating wheel, the fixing base has a second positioning shaft, the second positioning axle is a second rotating axle for the rotating plates, and the rolling wheel has a rolling axle connected to the rotating plates.
Preferably, a fastening rod is set between the rotating plates of the shock absorbing device for fastening the rotating plates, and a positioning shaft plate is arranged on the fixing base for fixing the first positioning shaft.
Preferably, the rolling wheel has an extended axle for fastening the oblique shock absorber.
Preferably, the carrier is a hand-operated cart, and the carrier main body further includes a positioning structure for fixing the carrier on a transporting vehicle.
Preferably, the carrier main body has a first and a second strips so as to protect a side of the carrier main body.
In accordance with another aspect of the present invention, a carrier for a wafer box is provided. The carrier includes a carrier main body for carrying at least one wafer box and an oblique shock absorber for protecting the carrier from a shock.
Preferably, a shock absorbing device is disposed on the carrier main body so as to protect the carrier from the shock, and the oblique shock absorber is disposed on the shock absorbing device.
Preferably, the carrier further includes a cover device disposed on the carrier main body, and a receiving room is formed between a cover device and the carrier main body for placing at least one wafer box therein.
The foregoing and other features and advantages of the present invention will be more clearly understood through the following descriptions with reference to the drawings, in which:
