Description

Technical Field

[0001] The utility model relates to the technical field of wafer boxes, in particular to a wafer turnover box capable of reducing the breakage rate. Background Art

[0002] Wafer refers to the silicon chip used in the manufacture of silicon semiconductor integrated circuits. Because of its round shape, it is called a wafer. Wafer boxes are mainly used to place and transport wafers in semiconductor production. In order to simplify transportation and minimize the risk of contamination, chip manufacturers use wafer boxes to transport and store wafers. Wafer boxes are needed in the process of wafer turnover. The common wafer turnover box in the prior art is the boat-shaped wafer box, which is a turnover container for carrying wafers and is used for transportation or shipment at on-site sites.

[0003] The top of the boat-shaped wafer box is open. Although this method can facilitate the placement of wafers, if the boat-shaped wafer box falls during transportation, the wafers are easily separated from the boat-shaped wafer box and moved out from the inside of the wafer box. The wafers moved out of the wafer box may come into contact with external objects and easily cause the wafers to be damaged, thereby affecting the normal use of the wafers. Therefore, a wafer turnover box that can reduce the breakage rate is needed to solve the above problem. Utility Model Content

The U-shaped anti-skid pads can increase the friction with the placement table, thereby greatly preventing the support plates from moving easily.

[0008] Preferably, any of the above solutions has a limit baffle fixedly connected to the outer surface of the boat-shaped box body.

[0009] Preferably, any of the above schemes has two side surfaces of the boat-shaped box body provided with taking slots for facilitating taking out the wafers.

After the wafer 3 is placed inside the boat-shaped box body 1, the two arc-shaped shielding covers 8 are rotated to make the two connecting plates 10 fit tightly. At this time, the two arc-shaped shielding covers 8 are connected under the magnetic connection of the two magnetic plates 12. When the boat-shaped box body 1 falls, if the position of the wafer 3 is displaced, the wafer 3 will move toward the direction of the arc-shaped shielding cover 8, and the arc-shaped shielding cover 8 will be on the top of the boat-shaped box body 1. The part is shielded, thereby preventing the wafer 3 from falling from the boat-shaped box body 1 to the outside, and the wafer 3 will contact the buffer pad 9 when it moves.
