[0001] The invention relates to the technical field of solar cells, in particular to a silicon wafer carrying flower basket. Background Art

[0002] With the rapid development and ever-changing updates of the photovoltaic industry, the texturing and alkali-polishing baskets used at the ends of the battery cells will be severely worn at the contact points between the basket teeth and the silicon wafer as the use time increases, so there are many problems when using the silicon wafer-bearing baskets.

[0003] The traditional silicon wafer support basket has the following problems: 1. As the use time of the texturing and alkali polishing baskets used at the cell end increases, the contact area between the basket teeth and the silicon wafer wears out, resulting in serious damage to the basket teeth area. 2. The damage of the tooth head of the basket teeth will cause liquid, misalignment and sticking of the wafer, resulting in poor product yield during the subsequent high-temperature diffusion and oxidation processes. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a silicon wafer supporting basket, which reduces the probability of damage to the tooth head of the basket, and improves the yield rate of the battery cell in subsequent high-temperature diffusion and oxidation processes by reducing the basket marks and liquid contamination of the silicon wafer caused by the basket teeth.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A silicon wafer carrying basket, comprising a panel, a frame, a first support rod, a second support rod, a third support rod and basket teeth. The top outer wall of the panel is fixedly connected to the frame, a placement chamber is provided between the panel and the frame, a first support rod is provided at the bottom of the rear side of the placement chamber through the outer wall of the panel, a second support rod is provided at the bottom of the middle end of the placement chamber through the outer wall of the panel, a third support rod is provided at the bottom of the front side of the placement chamber through the outer wall of the panel, and the top outer walls of the first support rod, the second support rod and the third support rod are all fixedly connected to basket teeth, and the basket teeth are evenly and symmetrically distributed.

[0006] Preferably, the inner walls at both ends of the front side of the frame plate are provided with engaging grooves, and the baffle plates are engaged and connected between the front ends of the frame plates through the engaging grooves.

[0007] Preferably, a bottom groove is provided at the bottom of the storage compartment through the top outer wall of the panel, the bottom grooves are evenly and symmetrically distributed, and the bottom grooves are located between the first support rod and the third support rod.

[0008] Preferably, a longitudinal movement bar is fixedly connected to the left outer wall of the frame plate near the middle end, and a longitudinal movement bar is fixedly connected to the right outer wall of the frame plate near the middle end.

[0009] Preferably, a transverse movement strip is fixedly connected to the outer wall near the middle end of the front side of the panel, and a transverse movement strip is fixedly connected to the outer wall near the middle end of the rear side of the panel.

[0010] Preferably, the top outer wall of the panel is fixedly connected with buffer blocks in sequence, and the buffer blocks are located at two ends of the top of the bottom groove.

[0011] The present invention provides a silicon wafer carrying flower basket, which has the following beneficial effects:

[0012] (1) This silicon wafer carrying basket is provided with basket teeth. Compared with the basket teeth used in the traditional silicon wafer carrying basket, the basket teeth are changed from a plate-shaped pointed head to a trapezoidal flat head, and the surface contact between the basket teeth and the silicon wafer is changed to a line contact, so as to reduce the friction area between the basket teeth and the silicon wafer, reduce the basket marks caused by the basket teeth, liquid contamination of the silicon wafer and other undesirable problems, and by providing the first support rod, the second support rod and the third support rod, the silicon wafer can be supported by the basket teeth in three stages to further disperse the friction force, reduce the problem of basket tooth damage, and because the relevant structural beam components cooperate with each other, the probability of partial damage to the basket tooth head is reduced.

[0013] (2) This silicon wafer carrying basket is provided with improved basket teeth, buffer blocks, bottom grooves and multiple support rods. The flat-headed basket teeth can reduce the problems of misaligned teeth, sticking and scratching between silicon wafers caused by the breakage and bending of the basket teeth. The bottom grooves are evenly arranged in multiple places. The shaking range of the silicon wafer can be limited by the bottom after the silicon wafer is placed to reduce the basket mark and liquid contamination. The buffer blocks are arranged at both ends of the bottom grooves to act as filling supports between the silicon wafers to reduce bumps and sticking. Because the relevant structural beam components work together, the basket mark and liquid contamination of the silicon wafer caused by the basket teeth are reduced, thereby improving the yield rate of the battery cell in the subsequent high-temperature diffusion and oxidation processes.
