Novel diffusion furnace battery piece conveying device

Abstract

Disclosed is a novel diffusion furnace battery piece conveying device, comprising a central shaft and a synchronizing wheel. A fixing surface is arranged on an outer side wall of a mounting end of the central shaft, and two ends of the mounting end of the central shaft are rotatably inserted into a left mounting frame and a right mounting frame respectively. The synchronizing wheel is sleeved on the mounting end of the central shaft between the left mounting frame and the right mounting frame. An insertion hole penetrates through the synchronizing wheel, a drilling hole is formed in the fixing surface in correspondence to the insertion hole, a jackscrew is inserted into the insertion hole, and an end, close to the mounting end of the central shaft, of the jackscrew extends into the drilling hole. By changing a fixing manner of the synchronizing wheel, the fixing surface of the central shaft capable of more firmly fixing the synchronizing wheel is designed, the drilling hole is formed in the surface of the fixing surface, the jackscrew is inserted into the insertion hole of the synchronizing wheel and extends into the drilling hole, and therefore the synchronizing wheel can be effectively prevented from shifting leftwards and rightwards. Thus, a situation of a pusher overload alarm of a diffusion furnace is avoided, the downtime of the diffusion furnace is reasonably shortened, and therefore the yield during diffusion of silicon wafers can be improved.

Description

technical field [0001] The invention relates to the technical field of cell diffusion equipment, in particular to a novel diffusion furnace cell conveying device. Background technique [0002] During the production process of photovoltaic modules, the cells need to be diffused, so the cells need to be transported into the diffusion furnace, but the diffusion furnace of the cells often has an overload alarm. If the treatment is not timely, the silicon chips will stay in the tube. If the time is too long, bad films will appear. [0003] In the prior art, such as the attached figure 1 As shown, the original fixed surface on the center shaft is a smooth flat surface, and it is necessary to use the top screw to push the fixed surface to prevent the synchronous wheel from shifting. However, the smooth fixed surface is easy to make the top screw loose, which is very unfavorable fixed, thereby causing the synchronous wheel to shift to one side, increasing the frictional resistance...

Problems solved by technology

[0002] During the production process of photovoltaic modules, the cells need to be diffused, so the cells need to be transported into the diffusion furnace, but the diffusion furnace of the cells often has an overload alarm. If the treatment is not timely, the silicon chips will stay in the tube. If the time is too long, there will be bad films

[0003] In the prior art, if the specification attached figure 1 As shown, the original fixed surface on the center shaft is a smooth flat surface, and it is necessary to use the top screw to push the fixed surface to prevent the synchronous wheel from shifting. However, the smooth fixed surface is easy to make the top screw loose, which is very unfavorable fixed, which causes the synchronous wheel to shift to one side, which increases the friction resistance during the movement, which also causes the occurrence of the above-mentioned push boat overload alarm
