Background

With the development of photovoltaic technology, silicon wafers are used as the main structures of photovoltaic cells, and the use frequency of the silicon wafers is also increasing. The silicon wafer is usually sliced by a slicing machine, before slicing the silicon rod, a lining plate bonded with the silicon rod is usually required to be bonded and fixed on a crystal support by using glue, and after the lining plate and the silicon rod are firmly bonded, the crystal support, the lining plate and the silicon rod which are bonded together are installed and fixed on the slicing machine, so that slicing processing is carried out on the silicon rod. After slicing the silicon rod, the lining plate and the crystal support, which are adhered with the silicon wafer, are integrally taken off from the slicing machine, and then degumming treatment is carried out to separate the lining plate from the crystal support. The crystal support is used continuously after being cleaned, and the lining plate is scrapped.

Therefore, the operation that the lining plate 11 is adhered to the crystal support 10 by using glue before slicing the silicon rod 20 and the lining plate 11 is separated from the crystal support 10 by degumming after slicing the silicon rod 20 can be avoided, the using amount of the glue and the workload of operators are reduced, and the slicing efficiency of the silicon rod 20 is improved. In addition, the damage to the crystal support 10 caused by the degumming treatment process can be avoided, and the service life of the crystal support 10 is prolonged.

In a specific application, the fixing tool described in the embodiments of the present application is used to fix the silicon rod 20. Before the silicon rod 20 needs to be sliced, the silicon rod 20 may be adhered to the liner plate 11 by an adhesive medium such as glue. Then, the first clamping groove 113 of the lining plate 11 is sleeved on the first clamping block 12, so that the first clamping block 12 can be at least partially embedded in the first clamping groove 113.

Referring to fig. 5, a schematic structural diagram of a crystal holder according to an embodiment of the present application is shown, and referring to fig. 6, a schematic structural diagram of a second clamping block according to an embodiment of the present application is shown. As shown in fig. 5, the second side 102 of the crystal support 10 is provided with a groove 104, the groove 104 is recessed toward the first side 101, and the first mounting hole 103 is disposed at the bottom of the groove 104. As shown in fig. 6, the second clamping block 13 is provided with a boss 131, the boss 131 is provided with a second mounting hole, the boss 131 is embedded in the groove 104, and the connecting piece 14 sequentially penetrates through the second mounting hole and the first mounting hole 103 to connect the second clamping block 13 to the crystal support 10.
