Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The foam box 1 and the cross partition 2 cooperate to form a four-in-one silicon wafer foam box packaging box. The foam box 1 is rectangular and is provided with a cover 5. The foam box 1 is open and is used for placing silicon wafers. The internal space of the foam box 1 is divided into four placement slots for placing silicon wafers by the cross partition 2. The cross partition 2 is connected to the foam box 1 by plugging. The cross partition 2 can also be removed to form the foam box 1 into a whole space, ensuring a wide range of applications. The cross section of the inner surface of the box is square, and the cross section of the cross partition 2 is cross-shaped. The four placement slots at the bottom of the box are The intersection of the core is concave, which ensures the storage effect of the processed silicon wafers. The protective structure 3 can prevent the silicon wafers from contacting and sticking together, which will affect the use effect of the silicon wafers. At the same time, the silicon wafers are effectively supported to avoid collision damage during transportation. The support structure 4 ensures the stability of the protective structure 3 in the placement groove and prevents it from leaving the placement groove. At the same time, the protective structure 3 is not completely fixed and stuck, and a small displacement can be provided for the protective structure 3 to achieve a buffering and shock-absorbing effect. It is highly practical, and the cover plate 5 can play a role in dust prevention.

[0019] The protective structure 3 includes a plurality of baffles 31, which are evenly arranged and a certain distance between two adjacent baffles 31. A handle 35 is fixedly mounted on the outer side surface of the baffle 31 on one side, and a screw 33 is screwed on the inner wall of the baffle 31 on this side. A turning handle 32 is fixedly mounted on the outer end of the screw 33, and a rotating shaft 34 is fixedly mounted on the other end of the screw 33. The outer end of the rotating shaft 34 is rotatably connected to the inner side surface of the baffle 31 on the other side, and the rotating shaft 34 and the screw 33 are clearance-matched with the other baffle 31.

[0020] When the protective structure 3 is needed, first place the silicon wafer in the gap between adjacent baffles 31, with only one silicon wafer placed in each gap. When all are placed, turn the handle 32 to drive the screw 33 to rotate. According to the screw connection between the screw 33 and the baffle 31 on one side, the screw 33 can be displaced on the inner wall of the baffle 31, thereby driving the baffle 31 on the other side that is rotatably connected to it to be displaced.

At the same time, the plug rod 42 will displace within the sleeve 44 to ensure the stability of the support blocks 41 on both sides. When it is necessary to support the protection structure 3, press the support blocks 41 on both sides to make them smaller than the gap between the protection structure 3 and the cross partition 2, and place the support structure 4 therein. According to the elastic force of the spring 43, the protection structure 3 will be supported and clamped in the placement groove. The elastic force of the spring 43 can be selected according to needs and will not affect the support effect.
