Description

Technical Field

[0001] The utility model relates to the technical field of solar cells, in particular to a flower basket device for placing silicon slices. Background Art

[0002] In the production of crystalline silicon solar cells, wet processing technology is an indispensable process flow, such as cleaning the damaged layer on the surface of the silicon wafer after cutting, pre-cleaning and texturing of the battery, etching and polishing, etc. The wet processing process will be used in the following processes. Since the tank-type wet processing process requires a large number of brittle silicon wafers to be evenly separated and immersed in each reaction tank one by one for a timed and quantitative chemical reaction, appropriate tools are needed to evenly place the silicon wafers in layers. The wet processing basket is currently the most important tooling and fixture for this step.

[0003] The existing flower basket includes two connecting plates, and a plurality of connecting columns are arranged between the two connecting plates. The connecting columns are provided with supporting teeth, and the silicon wafers are placed in the supporting teeth for texturing. After the silicon wafers are texturized, they are generally transported by a flower basket transport robot and a flower basket transport bracket. If the transport robot encounters a staff member suddenly appearing in front of the robot or an obstacle blocks it, the transport robot will brake urgently. During the emergency brake, due to inertia, the flower basket may tilt forward, and the forward tilt of the flower basket will cause the silicon wafer to tilt, causing the silicon wafer to be scratched and degraded, affecting the yield. The tilting of the silicon wafer may also cause damage to the supporting teeth. In addition, the existing flower baskets are generally integrally formed and cannot be disassembled. When the supporting teeth are damaged, the flower basket can only be replaced as a whole, and the cost of directly replacing the flower basket is high. Utility Model Content

[0034] Example 1

[0035] This embodiment 1 provides a basket device for placing silicon wafers, such as Figure 1-Figure 3 As shown, it includes an upper support plate 1 and a lower support plate 2 which are arranged relatively spaced along the longitudinal direction, and a support rod assembly for supporting silicon wafers is arranged between the upper support plate 1 and the lower support plate 2, wherein the upper and lower ends of the support rod assembly are detachably connected to the upper support plate 1 and the lower support plate 2 respectively through a locking mechanism 12, and when the supporting teeth are damaged, only the damaged part needs to be replaced, which greatly reduces the cost of use, and the support rod assembly includes a left support rod assembly, a right support rod assembly and a rear support rod assembly, and the left support rod assembly, the right support rod assembly and the rear support rod assembly enclose a U-shaped space for placing silicon wafers, so that the freedom of the silicon wafers in multiple directions is restricted, thereby being more stable during transportation and reducing the probability of scratches on the silicon wafers.

[0036] Specifically, see Figure 1 and Figure 2As shown, the left support rod assembly includes a first left support rod 8, a second left support rod 10 and a second middle support rod 9, the right support rod assembly includes a first right support rod 5, a second right support rod 7 and a first middle support rod 6, and the rear support rod assembly includes a first rear support rod 3 and a second rear support rod 4; the first left support rod 8 and the second left support rod 10 are spaced apart on the left side of the upper support plate 1 and the lower support plate 2, and the second middle support rod 9 is disposed between the first left support rod 8 and the second left support rod 10. Similarly, the first right support rod 5 and the second right support rod 7 are spaced apart on the right side of the upper support plate 1 and the lower support plate 2, the first middle support rod is disposed between the first right support rod 5 and the second right support rod 7, the first middle support rod 6 and the second middle support rod 9 correspond to each other and are located in the same straight line, and the first rear support rod 3 and the second rear support rod 4 are spaced apart on the front side of the upper support plate 1 and the lower support plate 2.

[0037] Please refer to Figure 1-Figure 3 As shown, the first left support rod 8, the second left support rod 10, the first middle support rod 6, the first right support rod 5, the second right support rod 7, the second middle support rod 9, the first rear support rod 3 and the second rear support rod 4 are all connected with a supporting tooth assembly 11 for supporting the silicon wafer. The supporting tooth assembly 11 includes supporting teeth 21. The supporting teeth 21 are arranged at intervals along the longitudinal direction, and the upper surface of the supporting teeth 21 is arranged in an arc shape. By reducing the contact area between the supporting teeth 21 and the silicon wafer, the formation of basket marks is reduced.

[0038] In this embodiment, in order to enhance the dehydration and liquid medicine removal capabilities of the flower basket device, a first liquid drainage groove 22 is provided in the middle of the supporting tooth 21, and a second liquid drainage groove 23 is provided on the corresponding supporting rod. The first liquid drainage groove 22 is connected to the second liquid drainage groove 23, and the second liquid drainage groove 23 is a through groove provided along the outer wall of the supporting rod. The liquid medicine remaining at the contact point between the silicon wafer and the supporting tooth 21 is collected in the second liquid drainage groove 23 through the first liquid drainage groove 22, and then discharged from the flower basket device through the second liquid drainage groove 23.

[0039] For the specific structure of the locking mechanism 12 in this embodiment, please refer to Figure 3-Figure 6As shown, the locking mechanism includes a locking stud 13 and a locking head. The end of each support rod is provided with a threaded hole that is screwed with the locking stud 13. The outer wall of each support rod is provided with a first locking cavity 16 that is connected with the threaded hole. The first locking cavity 16 is evenly arranged in four circles along the outer wall of the support rod, and a second locking cavity 17 that matches the first locking cavity 16 is provided at the junction of the upper support plate 1 and the lower support plate 2 with the end of the support rod assembly. The above-mentioned locking head is penetrated into the first locking cavity 16, and the length of the locking head is greater than the length of the first locking cavity 16. When the locking stud 13 is tightened with the threaded hole, one end of the locking head is forced to move the other end of the locking head to the second locking cavity 17 under the extrusion of the locking stud 13, so that the locking head fixes the upper support plate 1, the lower support plate 2 and the support rod assembly respectively.

[0040] In order to enable the lock to automatically reset after use, an elastic member such as a spring may be provided in the first locking cavity 16. However, this arrangement may cause the lock to be prone to falling off. Therefore, in this embodiment, the locking mechanism 12 further includes an annular elastic member 19, which is made of an elastic rubber material, such as Figure 6 As shown, the lock includes a first lock 18 and a second lock 20. The outer side wall of each support rod is provided with an annular groove matching the annular elastic member 19. The first lock 18 and the second lock 20 are respectively arranged at the two ends of the annular side wall of the annular elastic member 19. After the annular elastic member 19 is installed, there is an initial pre-tightening force between the annular elastic member 19 and the annular groove. When the second lock 20 is squeezed by the locking stud 13, it forces the first lock 18 to move toward the second locking cavity 17, so that the locks fix the upper support plate 1, the lower support plate 2 and the support rod assembly respectively. After the locking stud 13 is removed, the annular elastic member 19 provides elastic force for the first lock 18 and the second lock 20, so that they can automatically reset, and under the support of the annular elastic member 19, there is no risk of the locks being easily falling off.
