Through multiple groups of feeding pipes 304, electronic paste can be dispensed to each corresponding production link at one time, without the need for feeding operation one by one, thereby greatly shortening the overall feeding time and improving the efficiency of the production process. The bottom end of each feeding pipe 304 is communicated and installed with a feeding pipe 305, and the front end of each feeding pipe 305 is communicated and installed with a flow sensor 306.

[0025] Please refer to Figure 4In the embodiment, the stirring assembly comprises secondary helical blades 401, a secondary rotating shaft 402, a secondary motor 403, a mounting base 404, secondary supports 405 and a fixing plate 406. The mounting base 404 is horizontally arranged, a plurality of groups of secondary supports 405 are annularly arranged at the bottom end of the mounting base 404, the bottom end of each secondary support 405 is provided with a fixing plate 406, screw fixing holes are formed at the corners around the top end of each fixing plate 406, the secondary supports 405 connect the mounting base 404 and the fixing plates 406 to form a stable support structure, the secondary rotating shaft 402 is arranged at the center of the top end of the mounting base 404, the secondary helical blades 401 are sleeved on the secondary rotating shaft 402, the secondary motor 403 is arranged at the bottom end of the mounting base 404 and connected to one end of the secondary rotating shaft 402, and the secondary motor 403 drives the secondary rotating shaft 402 to rotate the secondary helical blades 401, so that the electronic paste forms a complex flow in the storage tank 1. For the multi-component material of the electronic paste, the metal powder, glass powder and organic carrier in the electronic paste are prone to precipitation or agglomeration due to the difference in density. The stirring action can effectively break the static stratification of the electronic paste, ensure that the components are fully mixed and uniform, and thus ensure the quality stability of the electronic paste.

[0026] When working, the workers extract the electronic paste from the external supply source into the storage tank 1 through the suction pump 101, and the first support 102 on both sides of the suction pump 101 ensures its stable operation. The electronic paste enters the storage tank 1 through the feeding pipe 104, and the connecting thread inside the feeding pipe 104 facilitates the connection with the external feeding equipment, ensuring the stability and sealing of the connection. At the same time, the stirring assembly in the storage tank 1 starts to work, the second motor 403 drives the second rotating shaft 402 to rotate, thereby driving the second spiral blade 401 to rotate. The mounting base 404 provides a stable mounting platform for the stirring assembly, and the multiple second supports 405 and fixed plates 406 annularly mounted at the bottom end are fixed in the storage tank 1 through the screw fixing holes, ensuring the stability of the stirring assembly. The stirring assembly prevents the electronic paste from precipitating and agglomerating in the storage tank 1, ensures the uniformity of the electronic paste composition, and the feeding pump 201 starts to work. The feeding pump 201 installed on the mounting hole 203 at the top center of the conveying pipeline 2 provides power for the flow of the electronic paste in the conveying pipeline 2. The electronic paste flows from the storage tank 1 to the feeding assembly through the conveying pipeline 2, enters the standby pipe 301, and the first motor 311 drives the first rotating shaft 310 to rotate, thereby driving the first spiral blade 309 to rotate. On the one hand, the first spiral blade 309 plays a certain stirring role, making the electronic paste more uniform. On the other hand, it can also accurately control the amount of electronic paste entering the standby pipe 301. The multiple vertically arranged feeding pipes 304 linearly connected at the front end of the standby pipe 301 receive the electronic paste from the standby pipe 301. The air pump 307 at the top end of the feeding pipe 304 drives the piston 308 through the push rod, controls the speed and flow of the electronic paste flowing out of the feeding pipe 304, and the connecting hole at the top end of the feeding pipe 304 provides a stable installation and movement channel for the push rod. The electronic paste flows out of the injection pipe 305 connected to the bottom end of the feeding pipe 304, and the flow sensor 306 installed at the front end of the injection pipe 305 monitors the flow of the electronic paste in real time, ensuring the accuracy of feeding. The heating plate 302 at the bottom end of the feeding pipe 304 can heat the electronic paste as needed to optimize the flowability of the electronic paste. The power supply 303 provides power guarantee for the first motor 311 and other equipment. The control panel 312 on one side of the group of feeding pipes 304 facilitates the centralized control and parameter adjustment of the entire feeding process by the operators.

[0027] Through the above steps, the design of the material feeding assembly helps to accurately feed the material. The first-stage spiral blade 309 and the first-stage rotating shaft 310 in the material pipe 301 are driven by the first-stage motor 311 to accurately control the electronic paste. By adjusting the rotating speed and time of the first-stage motor 311, the amount of electronic paste entering the material pipe 301 can be accurately controlled. At the same time, the stirring assembly in the storage tank 1 is cooperated to minimize the negative impact on the performance of the subsequent products due to the unevenness of the electronic paste. The flowability of the electronic paste changes at different temperatures. Some electronic pastes may become viscous or even solidify at low temperatures, affecting the smoothness of feeding. The heating plate 302 can heat the electronic paste in the material pipe 301 to an appropriate temperature, reducing its viscosity, so that it can pass through the feeding pipe 304 more smoothly. The design of the air pump 307 and the piston 308 in the injection pipe 305 further enhances the control of feeding. The air pump 307 can provide power for the piston 308 to move in the injection pipe 305. By controlling the pressure of the air pump 307 and the movement of the piston 308, the flow and speed of the electronic paste from the injection pipe 305 into the feeding pipe 304 can be accurately adjusted. The cooperation of the storage tank 1, the transportation pipeline 2 and the material feeding assembly improves the production efficiency and product quality. The electronic paste is stably transported from the storage tank 1 to the material feeding assembly through the transportation pipeline 2. The quality of the raw material is guaranteed during the whole process, the accuracy of feeding is improved, the overall performance and reliability of the subsequent products are improved, and the production efficiency is improved.
