Description

Technical Field

[0001] The utility model relates to the field of photovoltaic manufacturing, in particular to a screw hole structure which is compatible with silicon wafer flower baskets of different sizes. Background Art

[0002] Photovoltaic manufacturing refers to the industry that uses solar energy to generate electricity, and silicon wafers are one of the important raw materials for photovoltaic manufacturing. Silicon wafers are thin slices cut from silicon rods or ingots, and usually come in a variety of sizes. Different sizes of silicon wafers require different specifications of silicon wafer baskets to load and transport silicon wafers during the production process, so a silicon wafer basket that is compatible with silicon wafers of multiple sizes can greatly reduce production costs.

[0003] A wafer basket is a device used to load and transport wafers. It is usually made of metal or plastic and has multiple slots, each of which can accommodate a wafer. The wafer basket can protect the wafers from collision and contamination and is convenient for mechanical or manual operation. Although the existing wafer baskets that are compatible with wafers of various sizes can adjust the slot spacing, most of them have complex structures and high production costs. A few wafer baskets with simple structures are not stable enough and have high maintenance costs.

[0004] In view of the above-mentioned deficiencies, there is an urgent need for a mechanical structure applied to a silicon wafer basket to achieve compatibility with silicon wafers of different sizes. Utility Model Content

[0007] Furthermore, the limiting plate is a rectangular structure, and is provided with a plurality of slots corresponding to the silicon wafers.

[0008] Further, one limiting plate is provided on each of the left and right sides of the device, and the card slots on the two limiting plates are correspondingly arranged.

[0009] Further, the top plate has a rectangular structure, and the bottom plate has the same structure and is arranged oppositely.

[0010] As can be seen from the above description of the structure of the present utility model, compared with the prior art, the present utility model has the following advantages:

[0011] The structure of the present utility model is simple. The screw hole structure can adjust the distance between the left and right limiting plates of the silicon wafer carrier and the distance between the top plate and the bottom plate, avoiding the complex structure of using guide rails and other components, simplifying the manufacturing process and operation method, reducing the cost of manufacturing and modifying the silicon wafer carrier.
