[0065] a base 9, on which the first stirring device 1, the second stirring device 2, the second container 6 and the first container 4 can be arranged;
[0066] wherein the first stirring device 1 and the second stirring device 2 are connected through a material conveying pipe; the first container 4 and the second container 6 are arranged around the first stirring device 1 and the second stirring device 2; the first container 4 can be connected with the first stirring device 1 and the second stirring device 2 through a material conveying pipe; the second container 6 can be connected with the first stirring device 1 and the second stirring device 2 through a material conveying pipe.
[0067] The method for using the grouting device comprises the following steps:
[0068] I. Put each raw material (or slurry to be used) for forming the slurry into the first stirring device 1 for first stirring, and obtain the first target slurry after the first stirring; put the first target slurry into the second stirring device 2 for second stirring, and cool the slurry in the second stirring device 2 through the cooling system 3 during the second stirring to prevent overheating phenomenon caused by the stirring of the slurry; after the second stirring, the slurry can be introduced into a screen printing production line for use.
[0069] II. Put each raw material (or slurry to be used) constituting the slurry into the first stirring device 1, and perform first stirring. After the stirring is completed, the first target slurry is obtained. The first target slurry is put into the second container 6, and is left to stand. After the standing is completed, the first target slurry is put into the second stirring device 2, and is stirred for the second time. While the stirring is being performed, the slurry in the second stirring device 2 is cooled by the cooling system 3, so as to prevent overheating of the slurry caused by the stirring. After the stirring is completed, the slurry can be introduced into a silk screen printing production line.
[0070] In addition, the first container 4 is used to store the diluent, and a certain amount of diluent can be supplemented to the first stirring device 1 or the second stirring device 2 according to actual needs. The rotating speed of the stirring paddle in the first stirring device 1 can be controlled at 800-2000 r / min, and the rotating speed of the stirring paddle in the second stirring device 2 can be controlled at 200-500 r / min.
[0071] In summary, in the technical scheme of the present application, the second stirring device 2 is additionally provided on the basis of the first stirring device 1. The slurry is stirred by the first stirring device 1 and then stirred by the second stirring device 2. The slurry can be continuously and uniformly mixed and stirred, the problem of precipitation of the diluent caused by the slurry not being printed in time can be prevented, the amount of the slurry introduced at one time can be increased, and the production efficiency can be improved. In addition, in order to further alleviate the problem of precipitation of the diluent, an appropriate amount of diluent can be supplemented to the first stirring device 1 or the second stirring device 2 according to needs. The cooling system 3 is additionally provided in the second stirring device 2. The slurry in the second stirring device 2 can be cooled, the overheating phenomenon caused by the stirring of the slurry can be prevented, and the printing quality of the battery piece can be improved. While the printing quality is ensured, semi-automatic operation of the slurry can also be realized, so as to effectively reduce the labor cost.
[0072] In addition, the slurry injection device of the present application helps to realize semi-automatic operation of the slurry. The existing slurry injection device cannot continuously and uniformly mix and stir the silver slurry. In the process of silk screen printing, the heat generated by the automatic slurry injection machine cannot improve the printing quality, and long-term storage can also cause the silver slurry to dry, thereby reducing the printing quality. Therefore, the existing slurry injection device cannot ensure the printing quality, and many production processes still need to use manual operation to inject the slurry and the like to ensure the printing quality. After the device structure is optimized in the present application, the printing quality can be ensured without using manual operation to inject the slurry and the like. Therefore, semi-automatic operation of the slurry can be realized, so as to effectively reduce the labor cost.

The solar cell production system has the same advantages as the slurry injection device, which will not be repeated here. Specifically, the solar cell production system comprises the slurry injection device and a screen printing machine. In the solar cell production system, the slurry injection device is mainly used to accurately deliver slurry (such as silver slurry or aluminum slurry) to the screen printing machine, and the screen printing machine is used to print metal grid lines on the solar cell piece. Then, the solar cell piece printed with the metal grid lines is sent to a sintering process, sintered, and a metal electrode is formed, so that a solar cell piece containing the metal electrode is obtained.
