Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0022] The conveying device 3 includes a main conveying pipe 6, a double-headed connecting pipe 7 and a U-shaped pipe 8. The double-headed connecting pipe 7 is a concave structure. The main conveying pipe 6, the double-headed connecting pipe 7 and the U-shaped pipe 8 are smooth transition and integrally processed and formed structures. The main conveying pipe 6, the double-headed connecting pipe 7 and the U-shaped pipe 8 are all through structures. The double-headed connecting pipe 7 is located at the bottom of the main conveying pipe 6, and the U-shaped pipe 8 is located at the bottom of the double-headed connecting pipe 7. A first electromagnetic valve 9 is provided in the main conveying pipe 6, a second electromagnetic valve 10 is installed at the left end of the double-headed connecting pipe 7, and a gas inlet and outlet pipe 11 is provided at the right end. When the conductive silver glue in the production tank 2 is released for use, the staff starts the first electromagnetic valve 9 , then the conductive silver glue of the production tank 2 can flow into the main conveying pipe 6 of the conveying device 3, and the conductive silver glue flows into the double-head connecting pipe 7 and the U-shaped tube 8 for standby. The first electromagnetic valve 9 is closed, and the gas inlet and outlet pipes 11 are connected to the air compressor. The compressed air can enter the U-shaped tube 8 through the gas inlet and outlet pipes 11, so that the conductive silver glue in the U-shaped tube 8 is pushed to make the conductive silver glue flow. When the gas in the U-shaped tube 8 is discharged through the gas inlet and outlet pipes 11, the conductive silver glue refluxes, thereby making the conductive silver glue flow. When injecting glue, the second electromagnetic valve 10 is closed, and then the U-shaped tube 8 is inflated to use pressure injection.

[0023] Furthermore, the glue injection device 4 includes a glue injection tube 17 and a glue injection tray 18. The glue injection tube 17 is installed on the top of the glue injection tray 18.

The straight stirring blade 14 is provided with a plurality of groups and is installed on the stirring rod 12 in a row and equidistant manner. The bottom stirring blade 15 is a conical structure. The bottom stirring blade 15 is composed of a plurality of groups of stirring rods 16 of different lengths. The motor 13 is installed on the top of the production tank 2. The bottom driving end of the motor 13 is connected to the top of the stirring rod 12. When preparing the conductive silver glue material, the staff puts the conductive silver glue material into the production tank 2 through the feeding pipe, and then starts the motor 13. The motor 13 drives the stirring rod 12 to rotate, and the straight stirring blade 14 and the bottom stirring blade 15 on the stirring rod 12 are driven to stir the conductive silver glue material. The straight stirring blade 14 performs circular stirring, and the bottom stirring blade 15 performs conical stirring. The two stirring methods further improve the uniformity of mixing the conductive silver glue material.

[0025] Effectively, the production tank 2 is in a cylindrical structure, and the bottom of the production tank 2 is in a funnel-shaped structure.

The motor 13 drives the stirring rod 12 to rotate, and the straight stirring blades 14 and the bottom stirring blades 15 on the stirring rod 12 are driven to stir the conductive silver glue material. The straight stirring blades 14 perform circular stirring, and the bottom stirring blades 15 perform conical stirring. The two stirring methods further improve the uniformity of the mixing of the conductive silver glue material. The staff starts the first electromagnetic valve 9, and then the conductive silver glue in the production tank 2 can flow into the main conveying pipe 6 of the conveying device 3, and the conductive silver glue flows into the double-head connecting pipe 7 and the U-shaped pipe 8 for standby use. The first electromagnetic valve 9 is closed, the gas inlet and outlet pipes 11 are connected to the air compressor, and the compressed air can enter the U-shaped tube 8 through the gas inlet and outlet pipes 11, so that the conductive silver glue in the U-shaped tube 8 is pushed to make the conductive silver glue flow. When the gas in the U-shaped tube 8 is discharged through the gas inlet and outlet pipes 11, the conductive silver glue flows back, so that the conductive silver glue flows. When injecting glue, the second solenoid valve 10 is closed, and then the U-shaped tube 8 is inflated to use pressure injection. The staff opens the third solenoid valve 19 in the glue injection pipe 17, and then the conductive silver glue flows into the glue injection tray 18 through air pressure.
