Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a storage board for large-capacity semiconductor devices.

[Prior art and its problems]

Large-capacity semiconductor devices are usually assembled into a frame and stored in a panel, but since the weight of the device is large, it is important to make transportation and storage into the panel as easy as possible. Delicious.

Conventionally, semiconductor devices assembled in a frame are carried to the front of the panel by a forklift, crane, etc., but when it comes to assembling them into the panel, the gap between the hybrid and the device frame is so small that it is impossible to carry them in by a forklift. The device had to be manually moved within the panel and fixed in place. Moving heavy equipment back and forth and left and right in a narrow space inside a panel is not easy, requires a lot of effort, and is also dangerous.

[Purpose of the invention]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a storage board for semiconductor devices which eliminates the above-mentioned drawbacks and allows heavy semiconductor devices to be easily moved and fixed within the board by manual effort.

[Key points of the invention]

The present invention involves inserting air floating ball casters into the lower part of a groove-like raised bottom provided on the bottom of the frame of a semiconductor device, and blowing compressed air into the casters to levitate the device and move it to a predetermined position in the panel. This is a book about trying to fix the device by pulling it out.

[Embodiments of the invention]

FIG. 1 shows a storage board for semiconductor devices according to an embodiment of the present invention.

A semiconductor device 3 is housed in a fixed base 2 of a storage board 1, and air floating ball casters 4 are inserted into groove-like raised bottoms provided at both ends of the lower surface of the frame of the semiconductor device 3. The semiconductor device 3 is carried by a forklift or a crane and placed on an assembly table 5 provided on the front of the panel. Compressed air is blown into air floating ball casters to levitate the device and it is moved by hand to a fixed position inside the panel. At this point, the air is removed and the device is lowered and fixed.

Figures 2 to 4 show an air floating ball caster. The air floating ball caster 4 has a plurality of balls 42 protruding from the air layer 41. When compressed air is blown through the air hose connection port 43, the balls 42 protrude as shown in Fig. 3. It can roll on the floor while supporting the load. When the air is released, the ball sinks as shown in Figure 4.

FIG. 5 shows a semiconductor device housed in a board according to an embodiment of the present invention, and shows the bottom surface 3 of a frame body in which semiconductor elements and parts are incorporated.
Groove-shaped raised bottoms 32 are provided at both ends of the ball caster 1, and air floating ball casters 4 are fitted and fixed to these upper bottoms. FIGS. 6 and 7 show details of the caster attachment part, in which the casters 4 are bonded to the grooved raised bottom with adhesive and are fixed to the ends of the groove with claw-shaped clasps 6. When compressed air is blown into the caster 4, the ball 42 is released as shown in FIG.
protrudes and the semiconductor device 3 floats supported by the ball,
Since it can be moved by pushing manually, it is carried into a predetermined position in the panel, and when the air is removed there, the semiconductor device 3 is lowered as shown in FIG. Fixed by

FIG. 8 shows a semiconductor device housed in a board according to another embodiment of the present invention. Bottom surface 3 of the frame incorporating semiconductor elements and parts
Groove-shaped raised bottoms 32 are provided at both ends of 1, and removable air floating ball casters are inserted into these raised bottoms. Figures 9 to 11 show the details of the caster insertion part, and the caster 4 can be lightly inserted into the grooved raised bottom with the air removed. When compressed air is blown into the inserted caster, the semiconductor device 3 floats supported by the balls of the casters as shown in FIG. In this state, the casters 4 are pressed against the raised grooved bottom 32 and fixed by the coefficient of friction, so that they can be moved by human power. When the semiconductor device is moved to the position inside the panel and the air is removed from the casters, the first
As shown in FIG. 0, the semiconductor device 3 is lowered, the bottom plate 31 comes into close contact with the fixing base 2, and the semiconductor device 3 can be pulled out from the bottom by raising the casters 4. As shown in FIG. 11, the casters are taken out, and the semiconductor device 3 is fixed to the fixing base 2 with bolts 7 through the mounting holes 33. In this way, the casters are used only when loading and unloading the device, so they can be shared by many panels.

〔Effect of the invention〕

51 According to the present invention, large-capacity semiconductor devices can be easily carried in and out of the storage board by human power, which has the effect of reducing labor and improving maintainability.
