2results about How to "Guaranteed Diffusion Effect" patented technology

The present application relates to the field of battery production, and more particularly to a diffusion furnace for topcon battery production with uniform diffusion, comprising a furnace body and a furnace door thereon, a mixing bin is installed on the furnace body, a total gas inlet pipe is communicated and installed at the front end of the mixing bin, at least two groups of gas inlet branch pipes are communicated and installed on the total gas inlet pipe, and a stirring mechanism is arranged on the mixing bin, a connecting pipe is installed through between the chamber of the furnace body and the mixing bin, a cover is arranged in the mixing bin, and a power member is arranged on the mixing bin; a shunt bin is fixed in the chamber of the furnace body and is communicated and installed with the connecting pipe, a shunt hole is formed in the bottom wall of the shunt bin, and an adjusting mechanism is arranged in the shunt bin. By adding the total gas inlet pipe, the mixing bin and the stirring mechanism, each group of gas enters the total gas inlet pipe for preliminary mixing through the corresponding gas inlet branch pipe, and then enters the mixing bin for secondary mixing through the working of the stirring mechanism, which is beneficial to the full and uniform mixing of each gas and improves the subsequent diffusion effect.

The utility model relates to the technical field of bonding equipment provides a copper diffusion mechanism, including pressure mechanism and bearing cavity, the pressure plate of pressure mechanism sets up the top of bearing cavity, a plurality of pressure head posts of pressure plate sets up the lower part of pressure plate. Good contact is favorable to copper atom under the action of pressure more smoothly diffuses, improves the effect and consistency of diffusion.
