[0002] Currently in the field of photovoltaic power generation, common crystalline silicon solar cells are made on high-quality silicon wafers, which are made from pulled or cast silicon ingots through multi-wire saw cutting and subsequent processing. During the silicon wafer processing, the silicon wafers need to be adsorbed onto a hollow loading belt for transmission. The silicon wafers are transported one by one to a horizontal conveyor belt along the belt, realizing automated slice loading.

[0003] At present, in the process of using the existing silicon wafer feeding belt, a rubber strip is often set on the inner wall of the feeding belt to fit the suction mechanical part, so as to ensure the feeding stability. However, the existing rubber strip bonding part is easy to break, which affects the air tightness of the feeding belt, and the suction force is unstable, which makes it easy for the silicon wafer to fail to be adsorbed, or the silicon wafer is damaged by the strong suction force, thus affecting the feeding efficiency of the silicon wafer.

[0007] Furthermore, the groove is an annular structure.

[0008] Furthermore, a gear is fixedly connected to the outer wall of the driving shaft, the gear is meshed with the tooth groove, and the belt body is transmission-connected between the two gears.

[0009] Furthermore, a connector is plugged into the other side of the loading suction cup.

[0010] The beneficial effects of the utility model are:

[0011] 1. By clamping the suction head in the groove and using it in conjunction with perforation, the adhesive part of the adhesive strip is prevented from breaking, and the suction force of each suction head is ensured to be consistent, thereby stably adsorbing the silicon wafer and avoiding damage to the silicon wafer caused by excessive suction.

[0012] 2. The drive shaft rotates under the drive of the driving device, thereby driving the belt body to rotate, and then the silicon wafer is transported, which is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS
