  Next, a procedure for attaching the sheet 3 in the chip storage tray 1 will be described with reference to FIGS.

  In attaching the sheet 3, first, as shown in FIG. 8, the sheet 3 is placed on the surface of the sticking jig 7 with the adhesive surface 3 a facing upward. The sticking jig 7 is for suppressing the occurrence of a solid difference in the positional relationship between the upper plate 2 and the sheet 3, the tension state of the sheet 3, and the like. The affixing jig 7 is disposed on a flat jig main body 7a, a convex part 7b formed on the jig main body 7a and having a surface area corresponding to the upper plate 2, and both short sides of the jig main body 7a. And a positioning plate 7d provided with a recess 7c having the same dimensions as the recess 4c of the intermediate frame 4 (see FIG. 4A).

  Then, the four sides of the sheet 3 are lightly pulled to stretch out wrinkles and slack, and in this state, the upper plate 2 is covered from above the sticking jig 7. At this time, the position of the upper plate 2 is adjusted by adjusting the position of the upper plate 2 so that the protruding portion 2 c of the upper plate 2 is engaged with the concave portion 7 c of the sticking jig 7. Thereby, in the convex part 7b of the sticking jig 7, the back surface of the upper plate 2 and the bonding surface 3a of the sheet 3 are brought into close contact with each other, and the sheet 3 is bonded to the upper plate 2. The sheet 3 that protrudes from the jig body 7a is preferably cut at this point.

  Next, as shown in FIG. 9, the intermediate frame 4 is covered from above the lower table 5 so that the pedestal portion 5 b and the top plate 5 c of the lower table 5 are positioned in the hollow portion 4 m (see FIG. 4) of the intermediate frame 4. Then, the intermediate frame 4 is placed on the lower table 5. At this time, the intermediate frame 4 and the lower table 5 may be engaged and fixed to each other, or the intermediate frame 4 may be simply placed on the lower table 5 and both may be attached loosely. Good.

  Next, the connecting arm 4e of the intermediate frame 4 is moved outward to pull out the roller 4a and the rotating knob 4f (see FIG. 5), and the gap between the roller 4a and the long side surface 5h (see FIG. 6) of the lower table 5 is widened. . Next, the upper plate 2 and the sheet 3 are removed from the sticking jig 7 and the removed upper plate 2 and sheet 3 are placed on the lower table 5 as shown in FIG. At this time, the position of the upper plate 2 is adjusted so that the protrusion 2c of the upper plate 2 is engaged with the recess 4c (see FIG. 4A) of the intermediate frame 4, and the upper plate 2 and the sheet 3 are positioned. .

  Next, the sheet 3 (excess sheet) protruding from the top plate 5c of the lower table 5 is inserted into the gap between the roller 4a and the long side surface 5h of the lower table 5, and the adhesive surface of the sheet 3 is located below the roller 4a. It is assumed that 3a faces the roller 4a side. Such an operation is performed on both long side portions of the lower table 5, and the leading end portion of the extra sheet 3 is attached to the roller 4a.

  Next, the roller 4 a is rotated to wind up the sheet 3, and the sheet 3 protruding from the top plate 5 c of the lower table 5 is accommodated. At the same time, the connecting arm 4e is moved inward, and the roller 4a and the rotary knob 4f are pushed back inward. As a result, the upper plate 2 and the sheet 3 are fixed to the intermediate frame 4, and a tensile load is applied to the sheet 3 to prevent wrinkles and bending.

  Finally, the sheet 3 is sucked through the suction holes 5d of the top plate 5c, and the sheet 3 is held in close contact with the top plate 5c. As a result, it is possible to prevent the sheet 3 from being displaced or bent by an external force. As described above, the attachment of the seat 3 is completed, and the chip 6 can be accommodated (see FIG. 1).

  Thereafter, when removing the sheet 3, after the suction of the sheet 3 is released, the roller 4 a is rotated in the direction opposite to the winding direction, and the upper plate 2 and the sheet 3 are removed from the intermediate frame 4. When it is necessary to replace the sheet 3, the upper plate 2 and the sheet 3 are removed in the same procedure, and then a new sheet 3 is mounted. At this time, another set of the upper plate 2 and the intermediate frame 4 is prepared, and a new sheet 3 is previously mounted thereon, and the upper plate 2 and the intermediate frame 4 on which the new sheet 3 is mounted are attached to the old sheet 3. The upper plate 2 and the intermediate frame 4 may be replaced with each other.

  As described above, according to the present embodiment, since the roller 4a for winding up the extra sheet 3 is provided in the intermediate frame 4, the extra sheet 3 can be easily accommodated, and the sheet 3 can be accommodated by the roller 4a. A tensile load can also be applied to the sheet 3 by winding the wire. For this reason, it becomes possible to suppress wrinkles and bending of the seat 3 while reducing the labor of attaching the seat 3.

  Further, since the labor of attaching can be reduced, the replacement work of the sheet 3 is facilitated. Therefore, when the adhesiveness of the sheet 3 is weakened, the sheet 3 can be replaced immediately, and the chip 6 is removed. Accidents can be prevented. In addition, since the plurality of chips 6 are accommodated by adhering to the bonding surface 3a of the sheet 3, it is not necessary to prepare the plurality of chip accommodation trays 1 according to the dimensions of the chips 6, and economically excellent chip accommodation is possible. A tray can be provided.

  In addition, since the roller 4a is connected to the outside by the connecting arm 4e so that the roller 4a can be pulled out and the gap between the roller 4a and the pedestal 5b of the lower table 5 can be expanded and contracted, it becomes easy to insert an extra sheet 3 into the gap. The sheet 3 can be easily bonded to the roller 4a. As a result, the labor required for winding the sheet 3 can be reduced, and the working time can be further shortened.

  Further, since the chip storage tray 1 is composed of three members of the upper plate 2, the intermediate frame 4 and the lower table 5, and these are configured to be detachable, the seat 3 can be attached with the upper plate 2 and the intermediate frame 4 removed. Thus, work such as removal and replacement can be performed, and workability can be improved.

  In the above embodiment, after the intermediate frame 4 is placed on the lower table 5, the upper plate 2 and the sheet 3 are attached to the intermediate frame 4, but the upper plate 2 and the sheet 3 are attached to the intermediate frame 4. After that, they may be placed on the lower table 5.

  In the above embodiment, the sheet 3 is sucked and held by the suction holes 5d of the top plate 5c in order to suppress the displacement or bending of the sheet 3 due to external force, but the height of the support block 4b of the intermediate frame 4, Alternatively, the total height of the pedestal 5b and the top plate 5c of the lower table 5 may be adjusted to make the surface of the top plate 5c higher than the upper surface of the support block 4b of the intermediate frame 4. In this case, the tension of the sheet 3 can be strengthened, and the same effect can be obtained without providing the suction hole 5d.
