Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to an adjustable wet-process flower basket. Background Technology

[0002] In the photovoltaic cell manufacturing process, steps such as polishing, texturing and cleaning, and rework cleaning require the use of wet baskets to hold the silicon wafers. Currently, integrated welded wet baskets are widely used, mostly employing shark-tooth or diamond-shaped teeth to fix the silicon wafers. The teeth are directly fixed to the basket rod. If the tooth spacing is too small, it will produce severe tooth marks on the silicon wafer surface. If the tooth spacing is too large, the silicon wafer will have a larger range of movement between the teeth, which can easily lead to problems such as wafer sticking and fragmentation during automation and processing.

[0003] For manufacturers, cost reduction has always been a key development direction. Issues such as chipping, fragmentation, and cell adhesion all increase the cost of battery cell production. Currently, chipping is mainly addressed by methods such as soaking the basket in boiling water and increasing bubbling cycles. Cell adhesion and fragmentation are addressed by methods such as reducing the viscosity of the chemical solution and decreasing bubbling cycles. However, these methods are time-consuming and labor-intensive, and can easily affect the process, causing more defects and leading to higher costs. Therefore, it is necessary to design an adjustable wet-process basket to solve these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a lower-cost, more flexible adjustable wet-process flower basket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable wet-process flower basket, comprising two side plates and a flower basket rod disposed on the side plates, wherein the flower basket rod is provided with a plurality of locking teeth, the locking teeth being columnar with an elliptical cross section in the transverse direction and an isosceles trapezoidal cross section in the longitudinal direction, the locking teeth being movably disposed on the flower basket rod, the flower basket rod comprising a detachable top rod disposed on the top of the side plate, a plurality of side rods fixedly and parallelly disposed in the middle of the side plate, and a bottom rod fixedly and parallelly disposed at the bottom of the side plate.

[0006] As a further improvement of this utility model, a row of locking teeth is provided on the rod body of the top rod, the side rod, and the bottom rod, and the locking teeth are disposed on the top rod, the side rod, and the bottom rod through a rotating part.

[0007] As a further improvement of this utility model, the rotating part is columnar and passes through the top rod, the side rod, and the bottom rod.

[0008] As a further improvement of this utility model, a threaded area is provided at the bottom of the rotating part protruding from the rod body, and a locking part is connected to the threaded area for locking the rotating part to the rod body of the top rod, the side rod, and the bottom rod.

[0009] As a further improvement of this utility model, the top rod is one, the side rods are provided in two sets, and each set includes two side rods, and the bottom rods are two, and the two bottom rods are arranged in parallel.

[0010] As a further improvement of this utility model, the top rod is detachably mounted on the top of the side plate.

[0011] As a further improvement of this utility model, the rotating part of the locking tooth is connected by a synchronous transmission mechanism.

[0012] This utility model discloses an adjustable wet-process flower basket with adjustable movable teeth on the basket rod. The teeth, which are columnar structures with an elliptical cross-section and an isosceles trapezoidal cross-section, can change their spacing during rotation to adapt to different silicon wafer types and process requirements. This reduces the wafer adhesion rate, fragmentation rate, and tooth mark defect rate. Compared with existing methods for reducing wafer adhesion rate, fragmentation rate, and tooth mark defect rate, this utility model is more convenient to operate, lower in cost, and more flexible. For wafer adhesion, fragmentation, or tooth mark problems occurring in individual fixed positions on the flower basket, targeted tooth adjustment can be performed, that is, only the teeth at that position and its vicinity are adjusted, reducing workload. At the same time, it can also avoid defects in other normal positions caused by adjusting the entire flower basket rod. This has a significant effect on improving the stability of the production line process and reducing the manufacturing cost of solar cells. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0018] Reference Figure 1 , Figure 2 , an adjustable wet花篮(should be "wafer basket" probably) of this embodiment includes two side plates 1 and wafer basket rods 2 arranged on the side plates. A number of teeth 3 are arranged on the wafer basket rods 2. The teeth 3 are columnar with an oval cross-section in the horizontal direction and an isosceles trapezoid cross-section in the vertical direction. The teeth 3 are movably arranged on the wafer basket rods 2. The wafer basket rods 2 include a top rod 21 detachably arranged on the top of the side plates, multiple groups of side rods 22 fixedly arranged in parallel in the middle of the side plates 1, and bottom rods 23 fixedly arranged in parallel at the bottom of the side plates 1. The overall or surface of the side plates 1, the wafer basket rods 2 arranged on the side plates, the teeth 3 and other components are all heat-resistant and acid-alkali-resistant materials such as PVDF and PTFE.

[0019] Among them, there is one top rod 21, two groups of side rods 22 are provided, and each group includes two side rods 22. The four side rods 22 distributed in a rectangle are respectively located at the four corner positions of the rectangle. There are two bottom rods 23, and the two bottom rods 23 are arranged in parallel. The distance between the two bottom rods 23 is less than the distance between the side rods 22. When disassembling and installing the silicon wafers, the top rod 21 needs to be removed to avoid the top rod 21 affecting the normal placement of the silicon wafers.

[0020] Specifically, a row of teeth 3 are arranged on the rod bodies of the top rod 21, the side rods 22, and the bottom rods 23. The teeth 3 are arranged on the top rod 21, the side rods 22, and the bottom rods 23 through rotating parts. The rotating parts are columnar and penetrate the rod bodies of the top rod 21, the side rods 22, and the bottom rods 23. The teeth 3 rotate on the side rod 21, the bottom rod 22, and the pressing rod 23 with the rotating part as the center. Further, during the rotation of the teeth 3, the distance changes, such as Figure 3 the four states of a, b, c, and d in. The distances between the teeth are d1, d2, d3, and d4 respectively, and d1 < d2 < d3 < d4. For different process conditions, when the tooth marks on the surface of the produced silicon wafers are relatively serious, the tooth distance can be appropriately increased to avoid the small tooth distance causing oppression to the silicon wafers and resulting in uneven reaction. When problems such as batch wafer sticking and fragmentation occur during the automation and process, the tooth distance can be appropriately reduced to reduce the fragmentation caused by the vibration of the silicon wafers and avoid wafer sticking due to too small distance between the silicon wafers, thereby reducing the defective rate.

[0021] In addition, a threaded area is provided at the bottom of the rotating part protruding from the rod body, and a locking part is connected to the threaded area for locking the rotating part on the rod bodies of the top rod, the side rods, and the bottom rods. The locking part can be an adjusting nut. In this embodiment, each movable tooth 3 can be independently adjusted. For the problems of wafer sticking, fragmentation, or tooth marks at certain fixed positions of the wafer basket, only the teeth at this position and its vicinity can be adjusted, which not only increases the flexibility of adjustment, reduces the workload, but also avoids the occurrence of defective conditions at other normal positions due to overall adjustment. Embodiment 2

[0022] The difference between this embodiment and Embodiment 1 is that this embodiment also has a synchronous transmission mechanism 4, as shown in the reference. Figure 4 The synchronous transmission mechanism 4 is detachably connected to the rotating part of the locking teeth 3. The synchronous transmission mechanism 4 drives the locking teeth 3 on each rod to rotate synchronously, thus also suitable for synchronous adjustment. The synchronous transmission mechanism can adopt a gear transmission structure.
