Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology, and in particular relates to a silicon wafer-supported flower basket with positioning function. Background Technology

[0002] Silicon wafer carrier baskets are essential in the semiconductor photovoltaic manufacturing process. They are typically used to store silicon wafers and move them to various processing workstations. During solar cell production, the surface of the silicon wafers needs to be texturized. Based on their chemical properties, texturing can be divided into acidic and alkaline methods. In the texturing process, the silicon wafer is first placed in the basket, and then the entire wafer and basket are immersed in a chemical solution tank, allowing the silicon wafer to react with the solution. Once the texturized surface of the silicon wafer meets the set process requirements, it is then removed as a whole.

[0003] Traditional silicon wafer storage baskets mainly consist of a fixed frame and internal trays. Silicon wafers are placed into slots within the trays for storage. When the silicon wafers and baskets are removed from the chemical solution tank, their surfaces retain a significant amount of chemical solution. The simple structure of traditional silicon wafer storage baskets makes it difficult to quickly drain the residual solution, leading to substantial waste of chemical solution after the baskets are removed from the tank. This significantly increases the cost of chemical solutions. Therefore, some storage baskets are designed with an angle to achieve better drainage.

[0004] For example, Chinese utility model patent with patent publication number CN209016031U and publication date of June 21, 2019, discloses a silicon wafer holding basket structure, including a pair of basket side plates arranged opposite each other, a support member detachably connected between the basket side plates, a plurality of teeth evenly distributed on the support member, and a slot formed between adjacent teeth for receiving the silicon wafer. The support member includes a lower support member for supporting the silicon wafer upward, and the lower support member is inclined in the vertical direction.

[0005] The silicon wafer holding basket structure in this utility model patent has the following general structural principle: the basket structure, which is formed by the oppositely arranged basket side plates, support members, locking teeth and locking grooves, can accommodate silicon wafers. By the different heights of the basket side plates, the support members are tilted when the large basket is placed flat in the tank. This ensures that the silicon wafer is in contact with the large basket on only one side during the reaction in the tank, while the other side of the silicon wafer is in good contact with the reaction solution, thus avoiding appearance defects on the front of the battery.

[0006] However, the silicon wafer structure for holding a large flower basket still has at least the following shortcomings in actual use, which are the technical problems that this utility model aims to solve.

[0007] The existing flower basket side panels need to be reworked and redesigned, which is not practical. Furthermore, because the two flower basket side panels of different heights are designed as a single piece, they do not make stable contact with the material platform, resulting in poor drainage.

[0008] Therefore, in summary, there is an urgent need for a new type of silicon wafer-supported flower basket that is suitable for existing flower baskets and has stable positioning. Utility Model Content

[0009] This utility model provides a silicon wafer-supported flower basket with positioning function. By setting up a flower basket frame unit, a low positioning plate unit, and a high positioning plate unit, it can simultaneously meet the drainage requirements of the flower basket frame unit without changing its existing structure. The low positioning plate unit and the high positioning plate unit support the flower basket frame unit, allowing the flower basket frame unit to be placed at an angle, which facilitates drainage. Furthermore, the low positioning plate unit and the high positioning plate unit can be detachably connected to the flower basket frame unit. The low positioning plate unit and the high positioning plate unit can be reused by different batches of flower basket frame units, resulting in higher utilization rate. It has a positioning function and has tolerance space for the tilted placement of the flower basket frame unit, making the placement of the flower basket frame unit more stable.

[0010] The technical solution adopted by this utility model to solve the above problems is: a silicon wafer carrying basket with positioning function, including a basket frame unit, a low positioning plate unit set on the material platform and used to support one side of the basket frame unit, and a high positioning plate unit set on the material platform and used to tilt the basket frame unit by supporting the other side of the basket frame unit.

[0011] A further preferred technical solution is that the flower basket frame unit includes a first flower basket side plate and a second flower basket side plate, a flower basket support rod disposed on the first flower basket side plate and connected to the second flower basket side plate and used to support the silicon wafer, and a rack disposed on the flower basket support rod and used to insert the silicon wafer.

[0012] A further preferred technical solution is that the low positioning plate unit includes a low-position support plate disposed on the material platform and used to support the first flower basket side plate, and a low-position U-shaped baffle disposed on the low-position support plate and used to lock the first flower basket side plate.

[0013] A further preferred technical solution is that: the high positioning plate unit is disposed on the material platform and is used to support the high-position support plate of the second flower basket side plate, and a high-position C-shaped baffle is disposed on the high-position support plate and is used to lock the first flower basket side plate.

[0014] A further preferred technical solution is that the low positioning plate unit also includes a clearance notch disposed on the low-positioned C-shaped baffle and close to the outer side of the first flower basket side plate.

[0015] A further preferred technical solution is that the flower basket frame unit further includes a limiting groove provided on the first flower basket side plate and the second flower basket side plate, and the low-position support plate and the high-position support plate are provided with limiting protrusions for inserting into the limiting groove.

[0016] A further preferred technical solution is that the high-position support plate and the low-position support plate are provided with limiting post units for abutting against the second flower basket side plate and the first flower basket side plate.

[0017] A further preferred technical solution is that the limiting post unit includes a limiting pin disposed on the low-position support plate and the high-position support plate.

[0018] A further preferred technical solution is that the limiting post unit includes screws, and the connecting holes on the low-position support plate and the high-position support plate are used to install the screws.

[0019] A further preferred technical solution is that the connecting hole is a waist hole.

[0020] The beneficial effects of this utility model are: without changing the existing structure of the flower basket unit, it can simultaneously meet the drainage requirements of the flower basket unit. The low positioning plate unit and the high positioning plate unit support the flower basket unit, allowing the flower basket unit to be placed at an angle, which facilitates drainage. Furthermore, the low positioning plate unit and the high positioning plate unit can be detachably connected to the flower basket unit, and the low positioning plate unit and the high positioning plate unit can be used repeatedly for different batches of flower basket units, resulting in higher utilization rate. It also has a positioning function and has tolerance space generated by the tilting of the flower basket unit, making the placement of the flower basket unit more stable. Attached Figure Description

Detailed Implementation

[0032] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0033] As attached Figure 1-7 As shown, a silicon wafer support basket with positioning function includes a basket frame unit 1, a low positioning plate unit 2 disposed on a material platform a and used to support one side of the basket frame unit 1, and a high positioning plate unit 3 disposed on the material platform a and used to tilt the basket frame unit 1 by supporting the other side of the basket frame unit 1.

[0034] In this embodiment, the basket rack unit 1 is used to hold and accommodate the silicon wafer b. The low positioning plate unit 2 and the high positioning plate unit 3 are disposed on the material platform a, and can be fixedly disposed or detachably connected to the material platform a using screws. The spacing between the low positioning plate unit 2 and the high positioning plate unit 3 is set according to the size of the basket rack unit 1. The inclination of the basket rack unit 1 is affected by the height difference between the low positioning plate unit 2 and the high positioning plate unit 3, and the specific height difference is adjusted according to the size of the basket rack unit 1 and specific drainage requirements.

[0035] In use, the material platform a serves as a platform for placing the silicon wafer support basket. After the basket frame unit 1 is removed from the liquid tank, it is moved to the low positioning plate unit 2 and the high positioning plate unit 3 by a robotic arm or manually. A large amount of liquid adhering to the basket frame unit 1 or the silicon wafer b falls downwards due to gravity, thereby achieving a drainage effect. The low positioning plate unit 2 and the high positioning plate unit 3 stably support the basket frame unit 1, and can be supported by methods such as plug-in connection or baffle limiting, so that the basket frame unit 1 is placed stably.

[0036] The flower basket frame unit 1 includes a first flower basket side plate 11 and a second flower basket side plate 12, a flower basket support rod 13 disposed on the first flower basket side plate 11 and connected to the second flower basket side plate 12 and used to support the silicon wafer b, and a rack 14 disposed on the flower basket support rod 13 and used to insert the silicon wafer b.

[0037] In this embodiment, the flower basket unit 1 is mainly used to accommodate the silicon wafer b to be processed or after processing. The first flower basket side plate 11 and the second flower basket side plate 12 are connected by the flower basket support rod 13. To ensure that the silicon wafer b is placed safely and does not fall off easily, there can be multiple flower basket support rods 13. Multiple flower basket support rods 13 surround to form a cavity that can accommodate the silicon wafer b. The toothed rack 14 on the flower basket support rod 13 is inserted into the gap of the silicon wafer b. The overall structure of the flower basket unit 1 is stable.

[0038] The low positioning plate unit 2 includes a low-position support plate 21 disposed on the material platform a and used to support the first flower basket side plate 11, and a low-position U-shaped baffle 22 disposed on the low-position support plate 21 and used to hold the first flower basket side plate 11 in place.

[0039] In this embodiment, the low-position support plate 21 supports the first flower basket side plate 11, and the low-position chamfered baffle 22 encloses three sides of the low-position support plate 21. The low-position chamfered baffle 22 can restrict the horizontal movement of the first flower basket side plate 11.

[0040] The high positioning plate unit 3 is disposed on the material platform a and is used to support the high position support plate 31 of the second flower basket side plate 12, and the high position U-shaped baffle 32 is disposed on the high position support plate 31 and is used to lock the first flower basket side plate 11.

[0041] In this embodiment, the high-position support plate 31 is used to support the second flower basket side panel 12. Since the high-position support plate 31 is higher than the low-position support plate 21, the flower basket rack unit 1 placed on the high-position support plate 31 and the second flower basket side panel 12 is inclined, which facilitates drainage. At the same time, the high-position U-shaped baffle 32 and the low-position U-shaped baffle 22 have openings on one side to facilitate the placement of the flower basket rack unit 1, while enclosing it in other directions, making the placement of the flower basket rack unit 1 stable and preventing it from tilting and slipping.

[0042] The low positioning plate unit 2 also includes a clearance notch 23 disposed on the low position chamfered baffle 22 and close to the outer side of the first flower basket side plate 11.

[0043] In this embodiment, because the low positioning plate unit 2 is positioned low, after the flower basket frame unit 1 is placed, it tilts outward toward the low-positioned C-shaped baffle 22. To prevent the low-positioned C-shaped baffle 22 from bumping into the first flower basket side panel 11, and to ensure the limiting effect of the low-positioned C-shaped baffle 22, the clearance notch 23 is provided on the outer side of the low-positioned C-shaped baffle 22 near the first flower basket side panel 11, as shown in the attached figure. Figure 3 As shown.

[0044] The flower basket frame unit 1 also includes a limiting groove 15 provided on the first flower basket side plate 11 and the second flower basket side plate 12, and a limiting protrusion 4 for inserting into the limiting groove 15 is provided on the low support plate 21 and the high support plate 31.

[0045] In this embodiment, the limiting groove 15 is disposed on the first flower basket side plate 11 and the second flower basket side plate 12. When the flower basket frame unit 1 is placed, the limiting protrusion 4 matches the limiting groove 15, which can quickly position the flower basket frame unit 1 and further restrict the movement space of the flower basket frame unit 1. The limiting groove 15 can be an arc-shaped groove to increase the positioning effect.

[0046] The high-position support plate 31 and the low-position support plate 21 are provided with limiting post units 5 for abutting against the second flower basket side plate 12 and the first flower basket side plate 11.

[0047] In this embodiment, the limiting post unit 5 is used to abut against the sides of the second flower basket side plate 12 and the first flower basket side plate 11 to increase the limiting effect. At the same time, the position of the limiting post unit 5 can be set according to the size of the flower basket frame unit 1 to meet the support requirements of the flower basket frame unit 1.

[0048] The limiting column unit 5 includes a limiting pin 51 disposed on the low-position support plate 21 and the high-position support plate 31.

[0049] In this embodiment, the limiting pin 51 protrudes from the lower support plate 21 and the higher support plate 31, located on the side of the second flower basket side plate 12 and the first flower basket side plate 11.

[0050] The limiting post unit 5 includes screws 52, which are disposed on the low support plate 21 and the high support plate 31 and are connected in holes 53 for mounting the screws 52.

[0051] In this embodiment, the screw 52 is protruding to support the sides of the first flower basket side plate 11 and the second flower basket side plate 12. The screw 52 is disposed on the low support plate 21 and the high support plate 31 through the connecting hole 53, so that the screw 52 is detachable.

[0052] The connecting hole 53 is a waist hole.

[0053] In this embodiment, as shown in the appendix Figure 6 and attached Figure 7 As shown, the connecting hole 53 is a waist hole, and the screw 52 can be selectively set at a specific position in the connecting hole 53. When the flower basket unit 1 is larger in size, the screw 52 can be set at a position relatively close to the connecting hole 53. When the flower basket unit 1 is smaller in size, the screw 52 can be set at a position relatively far from the connecting hole 53. Furthermore, depending on the different sizes of the flower basket unit 1, the connecting hole 53 can be set on the inner or outer side of the lower support plate 21 and the upper support plate 31, thus improving practicality. The connection strength between the screw 52 and the connecting hole 53 can be achieved by adding shims or friction.

[0054] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this utility model. These are non-inventive modifications and are protected by patent law as long as they fall within the scope of the claims of this utility model.
