Description

Technical Field

[0001] The utility model relates to a crystal ingot turnover device, belonging to the field of turnover boxes. Background Art

[0002] In the semiconductor industry, turnover boxes are needed to transfer crystal ingots during the wafer manufacturing process. In the same factory, the production process of crystal rods and crystal ingots will produce crystal ingots of different diameters (6 inches, 8 inches, 12 inches) and heights (50mm-450mm). It is necessary to ensure the stability of the crystal ingot during the transfer process. Due to the different specifications of the ingots, the requirements for turnover boxes for ingots of different specifications are different. Therefore, turnover boxes of different specifications are needed to store ingots of different specifications, which leads to complicated specifications of turnover boxes in the factory, difficult management, and also affects the introduction of automated equipment. Utility Model Content

The present invention unifies the specifications of turnover boxes used to store crystal ingots of different specifications, thereby reducing the difficulty of managing the turnover boxes for storing crystal ingots.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a crystal ingot turnover device, including a turnover box, a liner is inserted in the turnover box, one side of the liner is evenly provided with a plurality of V-shaped grooves for storing crystal ingots, and the side of the liner facing away from the V-shaped groove is evenly provided with a plurality of circular grooves for storing crystal ingots, and a first ventilation groove is provided at the middle position of two parallel side surfaces of the liner, and a second ventilation groove is provided on two side surfaces of the liner adjacent to the first ventilation groove, a slot is provided at the middle position of one side surface in the first ventilation groove, an insert plate is inserted in the slot, a circular hole is provided at the middle position of the upper surface of the insert plate, a column rod is installed in the circular hole, two vertical grooves are symmetrically provided on the upper surface of the liner, the vertical grooves are connected with the first ventilation groove and the slot, the column rod is inserted in the vertical groove, both ends of the column rod are provided with threaded blind holes, a connecting rod is threadedly connected to the threaded blind hole, and a cross rod is connected and fixed to the end of the connecting rod away from the column rod.

[0005] Furthermore, the outer surface of one end of the connecting rod away from the cross bar is processed with an external thread, and the end of the connecting rod with the external thread is threadedly connected in the threaded blind hole. The end of the connecting rod away from the cross bar is provided with a limiting ring connected and fixed to the connecting rod, and the limiting ring is arranged on the side of the external thread facing the cross bar.

[0006] Furthermore, a spring is installed in the threaded blind hole, and the spring is arranged along the length direction of the threaded blind hole. A column head for sealing the open end of the threaded blind hole is installed at one end of the spring, and the column head is slidably installed in the threaded blind hole.

[0007] Further, a connecting piece is fixedly connected to the end of the spring away from the stigma, and the connecting piece is adhered to the innermost side in the threaded blind hole by glue.

[0008] Further, a plurality of ventilation holes penetrating the inner liner are provided on the upper surface of the inner liner. One end of the insertion plate is attached to the inner wall of the turnover box, and a plurality of semi-circular holes are evenly provided on the side of the insertion plate close to the inner wall of the turnover box.

[0009] Further, notches are provided at the upper positions of the two parallel side surfaces in the V-shaped groove (3), and a plurality of convex portions for supporting the ingot are evenly fixed on the inner wall of the circular groove.

[0010] Advantages of the utility model:

[0011] 1. Insert the inner liner into the turnover box. The inner liner is designed with two sides. The V-shaped groove processed on one side of the inner liner is used for the inverted placement of the ingot with a higher height, effectively preventing the ingot from rolling. The circular groove on the other side of the inner liner is used for the vertical storage of the ingot with a shorter height, which can prevent the left and right displacement of the vertically stored ingot. The inner liner is made of EPP material, which has certain anti-slip and shock-absorbing buffering properties. Finally, the specifications of the turnover boxes used for storing ingots of different specifications are unified, reducing the management difficulty of the turnover boxes for storing ingots.

[0012] 2. Process the first ventilation groove, the second ventilation groove, and the ventilation holes on the inner liner, which is convenient for air to flow into the turnover box when the inner liner is taken out, reducing the resistance to taking out the inner liner. At the same time, process notches in the V-shaped groove and install convex portions in the circular groove, which is convenient for taking out the ingot from the V-shaped groove and the circular groove.

[0013] 3. Insert the insertion plate into the slot until the column rod is in the vertical groove, completing the assembly of the structure formed by the insertion plate and the column rod and the inner liner. The insertion plate increases the contact area between the column rod and the inner liner. Screw the end of the connecting rod with an external thread into the threaded blind hole on the column rod, which is convenient for taking out the ingot in the V-shaped groove or the circular groove after taking out the inner liner from the turnover box by using the structure formed by the connecting rod and the cross bar, that is, it is convenient to take out the ingot in the large space outside the turnover box, which is more convenient than taking out the ingot in the narrow space inside the turnover box.

[0014] 4. When the connecting rod is screwed into the threaded blind hole, the connecting rod squeezes the stigma, and the stigma squeezes the spring, causing the spring to retract into the threaded blind hole. After the connecting rod disengages from the threaded blind hole, under the action of the spring's resilience, the stigma moves to the opening end of the threaded blind hole, realizing the real-time blocking of the threaded blind hole, preventing small debris from randomly entering the threaded blind hole and affecting the assembly of the connecting rod.
