Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cell manufacturing, in particular to a comparison device for troubleshooting causes of cell silicon wafer fragments. Background Art

[0002] Silicon material has become the main material of photovoltaic cells due to its good photoelectric conversion ability. However, due to the low hardness and brittleness of silicon material, the fragmentation of silicon wafers made of silicon material is relatively serious. How to reduce the fragmentation rate of photovoltaic cells has become a difficult problem that plagues the photovoltaic industry.

[0003] At present, the main cause of battery silicon wafer fragments lies in the irrationality of photovoltaic equipment. In the production and processing of photovoltaic cells, battery silicon wafers are inevitably transported or processed through multiple photovoltaic equipment. When the photovoltaic equipment clamps the surface of the battery silicon wafer, the clamping position of the battery silicon wafer is subjected to the pressure of the photovoltaic equipment and is very easy to break. Usually in this case, the staff tends to ignore the analysis of the cause of the battery silicon wafer fragments, and thus fail to discover and solve the problems of the photovoltaic equipment in a short time, resulting in continuous battery silicon wafer fragments, thereby affecting the production efficiency of photovoltaic cells and causing losses.

[0030] Specifically, the material of the substrate 1 in the utility model is a PVC plastic board; the equipment clamping point label group in the utility model can be a clamping point position formed when a photovoltaic device clamps the surface of the battery silicon wafer 25, or it can be a clamping point position formed when multiple photovoltaic devices clamp the surface of the battery silicon wafer 25. In the specific comparison process, the equipment clamping point label group can be set according to the different photovoltaic devices that the battery silicon wafer 25 passes through during the production and processing process.

[0031] In a specific implementation manner, the direction label set 4 of the present invention can be engraved on the substrate 1 by etching, or the direction label set 4 can be made into a physical label and pasted on the substrate 1 .

[0032] A silicon wafer placement groove 3 matching the size of the battery silicon wafer 25 is opened on the substrate 1, the circular comparison frame 2 is connected to the outer periphery of the silicon wafer placement groove 3, and the direction label group 4 is connected to the substrate 1 and located above the upper side 21 of the circular comparison frame 2. When the staff needs to determine the cause of the battery silicon wafer 25 being fragmented, the broken battery silicon wafer 25 can be taken out of the flower basket or the quartz boat, and according to the placement direction of the battery silicon wafer 25 in the flower basket or the quartz boat, the battery silicon wafer 25 is placed in the silicon wafer placement groove 3 in the direction pointed by the flower basket opening direction label 41 or the quartz boat opening direction label 42 in the direction label group 4, and the cause of the battery silicon wafer 25 being fragmented is determined without changing the placement direction of the battery silicon wafer 25, thereby improving the accuracy of the result of the determination of the cause of the fragmentation.

[0033] By placing the battery silicon wafer 25 in the silicon wafer placement groove 3, connecting the equipment clamping point label group to the circular comparison frame 2, and connecting the equipment clamping point label group to the circular comparison frame 2, and then comparing the broken position of the battery silicon wafer 25 with the equipment clamping point label group, the staff can judge the cause of the fragmentation of the battery silicon wafer 25 according to the position comparison result, and then inspect and repair the corresponding position of the photovoltaic equipment to reduce the phenomenon of continuous photovoltaic cell fragments caused by the same photovoltaic equipment, thereby reducing the impact on production efficiency.

[0034] Optionally, the equipment clamping point label group includes a wet flower basket clamping point label group, a flower basket clamping point label group, a quartz boat clamping point label group and an external flipping equipment clamping point label group;

[0035] The wet flower basket clamping point label group includes a first wet flower basket side rod clamping point label 5, a second wet flower basket side rod clamping point label 6 and a wet flower basket bottom rod clamping point label 14, the flower basket clamping point label group includes a first flower basket side clamp clamping point label 7, a second flower basket side clamp clamping point label 8 and a flower basket tooth clamping point label 12, the quartz boat clamping point label group includes a first quartz boat side rod clamping point label 9, a second quartz boat side rod clamping point label 10 and a quartz boat top tooth clamping point label 11, and the external flipping device clamping point label group includes a flipping tooth clamping point label 13;

[0036] The first wet flower basket side rod clamping point label 5, the first flower basket side clamp clamping point label 7 and the first quartz boat side rod clamping point label 9 are all connected to the left side 23 of the circular comparison frame 2, the second wet flower basket side rod clamping point label 6, the second flower basket side clamp clamping point label 8 and the second quartz boat side rod clamping point label 10 are all connected to the right side 24 of the circular comparison frame 2, and the quartz boat top tooth clamping point label 11, the flower basket support tooth clamping point label 12, the flip support tooth clamping point label 13 and the wet flower basket bottom rod clamping point label 14 are all connected to the lower side 22 of the circular comparison frame 2.

[0037] Specifically, the first wet flower basket side rod clamping point label 5 and the second wet flower basket side rod clamping point label 6 in the utility model are respectively the wet flower basket left side rod clamping point label and the wet flower basket right side rod clamping point label; the first flower basket side clamp clamping point label 7 and the second flower basket side clamp clamping point label 8 in the utility model are respectively the flower basket left side clamp clamping point label and the flower basket right side clamp clamping point label; the first quartz boat side rod clamping point label 9 and the second quartz boat side rod clamping point label 10 in the utility model are respectively the quartz boat left side rod clamping point label and the quartz boat right side rod clamping point label; therefore, the structure in the photovoltaic device corresponding to the device clamping point label group in the utility model is the wet flower basket left side rod, the wet flower basket right side rod, the wet flower basket bottom rod, the flower basket left side clamp, the flower basket right side clamp, the flower basket support teeth, the quartz boat left side rod, the quartz boat right side rod, the quartz boat top teeth and the flip support teeth.

[0038] It should be noted that the connection position of the device clamping point label group on the circular comparison frame 2 needs to correspond one-to-one with the position of the clamping point formed by the photovoltaic device on the surface of the battery silicon wafer 25 to ensure the accuracy of the comparison result.

[0039] Optionally, the four side dimensions of the silicon wafer placement groove 3 are all 210mm, the upper side 21 and the lower side 22 of the circular comparison frame 2 are each provided with 22 scale grids, the width of each scale grid is 10mm, and the 22 scale grids of the upper side 21 and the lower side 22 are connected with digital labels of 0 to 21 from left to right in sequence, the left side 23 of the circular comparison frame 2 is provided with 21 scale grids, the width of each scale grid is 10mm, and the 21 scale grids of the left side 23 are connected with digital labels of 1 to 21 from bottom to top, and the right side 24 of the circular comparison frame 2 is provided with 23 scale grids, the width of each scale grid is 10mm, and the 23 scale grids of the right side 24 are connected with digital labels of 0 to 21 and 0 from bottom to top.

[0040] It should be noted that in order to ensure the accuracy of the comparison results, the size of the silicon wafer placement groove 3 of the utility model is 210mm×210mm, so it can only compare the battery silicon wafer 25 with a size of 210mm×210mm. The connection position of the equipment clamping point label group on the circular comparison frame 2 is closely related to the size of the battery silicon wafer 25. Therefore, the inner frame size of the circular comparison frame 2 of the utility model also needs to be set to 210mm×210mm to ensure that during the comparison process, the connection position of the equipment clamping point label group connected to the circular comparison frame 2 is consistent with the clamping point position formed by the photovoltaic device on the surface of the battery silicon wafer 25.

[0041] If it is necessary to determine the cause of the fragmentation of battery silicon wafers 25 of other sizes, the silicon wafer placement groove 3 that matches the size of the battery silicon wafer 25 can be reprocessed on the substrate 1. When the size of the battery silicon wafer 25 changes, the position of the clamping point formed by the photovoltaic device and the surface of the battery silicon wafer 25 changes, so that the connection position of the device clamping point label group on the circular comparison frame 2 also changes. Therefore, it is necessary to remake and connect the circular comparison frame 2 that matches the size of the silicon wafer placement groove 3 to ensure the accuracy of the comparison result.

[0042] Optionally, when the size of the silicon wafer placement slot 3 is 210 mm×210 mm, the first wet flower basket side rod clamping point label 5 is connected between the digital label 19 and the digital label 20 of the left side edge 23, the digital label 12, the digital label 4 and the digital label 5 are connected, the digital label 12 and the digital label 13 of the left side edge 23 are connected to the first flower basket side clamp clamping point label 7, and the first quartz boat side rod clamping point label 9 is connected between the digital label 18 and the digital label 19 of the left side edge 23, and the digital label 2 and the digital label 3 are connected;

Figure 2 The fragments of the battery silicon wafer 25 are respectively located at the number label 14 on the lower side 22 of the circular comparison frame 2 and the number label 12 on the right side 24. The number label 14 on the lower side 22 corresponds to the clamping point label 14 of the wet flower basket bottom rod, and the number label 12 on the right side 24 corresponds to the clamping point label 6 of the second wet flower basket side rod.
