[0040] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0041] This utility model embodiment provides a placement box.
[0042] Reference Figure 1 The placement box includes:
[0043] Box 1, Box 1 includes a placement slot 11 with one side open, the placement slot 11 is used to hold defective solar cells;
[0044] Locking component 2 is provided on the housing 1 and is used to lock the housing 1 to the solar cell production equipment.
[0045] With the locking component 2, the storage box of this invention can be firmly fixed to the solar cell production equipment. This innovation not only greatly facilitates the storage and retrieval of defective cells generated during the solar cell production process, but also significantly optimizes the workshop space configuration, effectively reducing the floor space occupied by traditional storage cabinets in workshop aisles, thus making more rational and efficient use of workshop space. More importantly, the locking component 2 effectively reduces vibrations caused by the movement of the storage cabinet or external environmental factors, thereby reducing the risk of damage to defective cells during storage and ensuring the integrity of the defective cells.
[0046] In addition, the placement box of this utility model adopts a design with one side open, which makes the placement and collection of defective pieces more efficient and is conducive to a significant improvement in workshop work efficiency.
[0047] It should be noted that defective wafers refer to silicon wafers (or silicon wafers coated with functional films) that have defects during the solar cell production process due to various reasons (such as mechanical stress, improper operation, equipment failure, or contamination), thus failing to meet quality standards or becoming damaged, broken, or even split. These silicon wafers, either due to defects or impaired physical integrity, cannot be directly used in subsequent battery manufacturing stages.
[0048] Reference Figure 2 In some embodiments, the box body 1 includes a bottom plate and side plates 12 arranged circumferentially along the bottom plate, and the bottom plate and side plates 12 enclose a rectangular placement groove 11.
[0049] The placement slot 11 of this invention is rectangular, which has a high degree of compatibility with the shape of silicon wafers (usually rectangular or square wafers). This is beneficial for maximizing the use of space in the placement slot 11 and for the neat and stable placement of defective wafers, thus having high practicality and economic value.
[0050] Reference Figure 2 In some embodiments, the side plate 12 includes two long side plates 121 and two wide side plates 122 arranged opposite to each other, wherein one of the long side plates 121 is a protruding side plate 1211 that protrudes from the opening edge of the other side plates 12, and a locking member 2 is provided on the protruding side plate 1211.
[0051] The protruding side plate 1211 provides installation space for the locking component 2, which can more easily dock and lock with the solar cell production equipment without cumbersome adjustments, thus improving the stability and efficiency of locking.
[0052] Reference Figure 3 The height of the protruding side plate 1211 is h1, and the height of the other long side plate 121 opposite to the protruding side plate 1211 is H1. h1 is 30mm to 70mm higher than H1.
[0053] Reference Figure 2 In some embodiments, the locking component 2 includes a plurality of screw holes 21, which are located near the edge of the protruding side plate 1211 away from the base plate. The screw holes 21 are used to lock the protruding side plate 1211 onto the solar cell production equipment by means of bolts. Further, the number of screw holes 21 is four, and the four screw holes 21 are arranged in a row on the edge of the protruding side plate 1211 away from the base plate.
[0054] The screw hole 21 provides sufficient locking space. When the box needs to be fixed to the production equipment, the bolts and screw holes 21 can be tightly fitted together to make the protruding side plate 1211 securely and firmly locked to the solar cell production equipment, thus achieving locking and fixing.
[0055] This locking method not only significantly improves the connection stability between the placement box and the production equipment, effectively preventing defective wafers from shaking or falling off during storage, but also makes the locking process simpler and faster.
[0056] Reference Figure 2 In some embodiments, except for the protruding side plate 1211, the opening edges of the other side plates 12 on the side away from the bottom plate are bent downward to form a bent portion 123.
[0057] The presence of the bend 123 effectively avoids the risk of operators being scratched by what would otherwise be sharp edges when in contact with the placement box. This downward bend design makes the edge of the side panel 12 facing away from the bottom plate rounded and smooth, reducing the possibility of accidental scratches and providing a more user-friendly and safer operating environment for operators.
[0058] Reference Figure 1 In some embodiments, defective sheets include rework sheets and fragments;
[0059] The placement slot 11 is provided with a rework piece placement sub-box 3 with one side open and a fragment placement sub-box 4 with one side open. The rework piece placement sub-box 3 is used to place rework pieces, and the fragment placement sub-box 4 is used to place fragments.
[0060] To accommodate different types of defective wafers, this invention includes a rework wafer placement sub-box 3 and a fragment placement sub-box 4. The rework wafer placement sub-box 3 is designed for rework wafers that are undamaged around the edges and, after preliminary inspection, are expected to be restored to quality standards through reprocessing. The fragment placement sub-box 4 is used to store fragments that are damaged, difficult to repair, and can only be disposed of as waste.
[0061] The aforementioned categorized placement system enhances the classification and management of defective wafers. Operators can easily achieve categorized storage by simply placing different types of defective wafers into their corresponding storage boxes. This improves work efficiency and reduces errors and waste caused by improper classification or confusion.
[0062] Reference Figure 1 In some embodiments, the rework piece placement sub-box 3 is detachably connected to the placement slot 11; and / or, the fragment placement sub-box 4 is detachably connected to the placement slot 11.
[0063] The rework piece placement sub-box 3 and the placement slot 11, as well as the fragment placement sub-box 4 and the placement slot 11, are all connected in a detachable manner. Removing or placing the rework piece placement sub-box 3 and the fragment placement sub-box 4 from or into the placement slot 11 requires no complex operations or tools. This feature allows operators to quickly and accurately complete the action when it is necessary to remove or place defective pieces, without wasting time in tedious fixing and unbinding processes.
[0064] Furthermore, the detachable connection facilitates the cleaning and maintenance of the entire placement box. When dust, debris, or other contaminants accumulate inside the placement box, operators can easily remove the rework piece placement sub-box 3 or the fragment placement sub-box 4 from the placement slot 11 for thorough cleaning, ensuring the hygiene of the placement box and the storage environment.
[0065] Reference Figure 1 In some embodiments, the fragment placement sub-box 4 is provided with a handle 41. The presence of the handle 41 makes it easier for operators to grasp and move the fragment placement sub-box 4, making the circulation of the fragment placement sub-box 4 in the workshop more efficient and orderly. Furthermore, the handle 41 is located on one side of the open surface of the fragment placement sub-box 4.
[0066] Reference Figure 2 In some embodiments, a partition 13 is provided inside the box body 1, and a rework piece placement sub-box 3 and a fragment placement sub-box 4 are located on both sides of the partition 13.
[0067] By adding a partition 13, the areas of the rework piece placement sub-box 3 and the fragment placement sub-box 4 in the placement slot 11 are clearly defined, which greatly improves the convenience of management and identification.
[0068] Reference Figure 4In some embodiments, the rework piece placement sub-box 3 is provided with two rework piece placement slots 31, and the two rework piece placement slots 31 are arranged along the width direction of the box body 1.
[0069] Refer to the return Figure 1 The fragment placement sub-box 4 is equipped with a fragment placement slot 42.
[0070] In actual production, there may be two different types of rework sheets: one type requires rework before being transferred to the production equipment, and the other type requires rework after being processed by the corresponding solar cell production equipment. By setting up two rework sheet placement slots 31, these two types of rework sheets can be stored separately, which facilitates the subsequent classification and handling of problems that occur in different processes and improves the efficiency of rework sheet processing.
[0071] The fragment placement sub-box 4 is equipped with a fragment placement slot 42 for collecting and processing fragments generated during the production process. This design not only meets practical needs but also embodies the concept of minimalist design. One fragment placement slot 42 is sufficient to hold the fragments generated during the production process, eliminating the need for excessive fragment placement slots 42, thereby reducing production costs and material waste.
[0072] Reference Figure 3 In some embodiments, the lengths of the box body 1, the rework piece placement sub-box 3, and the fragment placement sub-box 4 are L1, L2, and L3, respectively, with L1:L2:L3 being 500-560:235-295:185-235.
[0073] The widths of box 1, rework piece placement sub-box 3, and fragment placement sub-box 4 are W1, W2, and W3, respectively, with W1:W2:W3 being 170-180:150-160:150-160.
[0074] The heights of box 1, rework piece placement sub-box 3, and fragment placement sub-box 4 are H1, H2, and H3, respectively, with H1:H2:H3 being 180~220:140~160:140~160.
[0075] The length, width, and height ratios provided above offer a basic dimensional framework for the design of Box 1, Rework Sheet Sub-box 3, and Fragment Sub-box 4. In actual use, these ratios can be fine-tuned according to the required material thickness to maximize the dimensional adaptability of Box 1, Rework Sheet Sub-box 3, and Fragment Sub-box 4.
[0076] Further, L1:L2:L3 can be 500cm~560cm:235cm~295cm:185cm~235cm. W1:W2:W3 can be 170cm~180cm:150cm~160cm:150cm~160cm; H1:H2:H3 can be 180cm~220cm:140cm~160cm:140cm~160cm. For example, the external dimensions of the box body 1 are L530*W175*H200 mm, the external dimensions of the rework piece placement sub-box 3 are L265*W155*H150 mm, wherein the dimensions of the rework piece placement slot 31 located in the rework piece placement sub-box 3 are L215*W40*H125 mm, and the external dimensions of the fragment placement sub-box 4 are L215*W155*H150 mm.
[0077] In some embodiments, the material of the rework piece placement box 3 is a cushioning material.
[0078] Preferably, a cushioning material with high resilience and durability can be selected as the material for preparing the rework piece placement box 3, such as high-density foam, memory foam, or specially designed elastic plastic. These materials can not only effectively absorb impacts, but also maintain their shape and performance during long-term use.
[0079] Furthermore, during the production process, the material and thickness range of the rework piece placement sub-box 3 can be adjusted based on the size and weight of the rework piece, as well as the potential impact during transportation and storage. For example, for more flexible cushioning materials, the thickness can be increased to improve the cushioning effect; while for stronger cushioning materials, the thickness of the rework piece placement sub-box 3 can be appropriately reduced to lower costs and weight.
[0080] Reference Figure 3 Preferably, the material of the rework piece placement box 3 is foam, and the thickness of the foam is D, where D is 10mm to 35mm. This thickness of foam has both good cushioning effect and certain strength, which can not only provide better cushioning and shock absorption for the rework piece, but also help improve the durability of the rework piece placement box 3.
[0081] In some embodiments, the fragment placement sub-box 4 is made of metal or alloy, and the box body 1 is made of metal or alloy.
[0082] By using metal or alloy as the material for the fragment placement sub-box 4 and the box body 1, the structural stability and durability of the fragment placement sub-box 4 and the box body 1 can be significantly enhanced. Furthermore, in this embodiment, the box body 1 possesses structural stability and load-bearing capacity, which complements the flexibility of the rework piece placement sub-box 3, thus both stabilizing the structure and providing precise protection for the rework pieces, maximizing the advantages of the materials.
[0083] Furthermore, the materials for the fragment placement sub-box 4 and the box body 1 can be cold-rolled steel. The surface of the cold-rolled steel is polished to remove burrs from the edges. Precision grinding and polishing is preferred to avoid environmental pollution caused by chemical electrolytic polishing. In addition, the surface of the cold-rolled steel can be coated with paint to enhance its protective effect. The finished fragment placement sub-box 4 and box body 1 are cleaned according to cleanroom standards and covered with a protective film to reduce impurity contamination.
[0084] The above provides a detailed description of the placement box disclosed in the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the placement box and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
