Description

Technical Field

[0001] This utility model relates to the field of manufacturing equipment technology in the photovoltaic industry, and in particular to a silver paste mixing and feeding device. Background Technology

[0002] In the photovoltaic industry, the coating and printing of printing paste is an important production process. Silver paste, as a material widely used in electronics, photovoltaics and other fields, has special physicochemical properties. On the one hand, silver paste has extremely low activity, resulting in weak interaction between the silver particles inside, making it difficult to flow and disperse spontaneously. On the other hand, silver paste has very poor fluidity, exhibiting high viscosity and high yield stress, similar to a semi-solid substance.

[0003] When using rollers for coating, the silver paste needs to be processed to a state with high flow activity. Existing silver paste mixing devices have problems such as poor mixing effect and inability to effectively bring the silver paste to the ideal active state when processing silver paste with this special property. This makes it difficult to meet the high-quality requirements of the photovoltaic industry for silver paste processing, and affects the subsequent coating and printing quality and production efficiency.

[0004] To address the existing problems, there is a need for a silver paste stirring device used in the photovoltaic industry to stir silver paste to achieve the active state required for coating and printing. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, such as poor silver paste stirring effect and difficulty in achieving the active state required for coating and printing, this utility model provides a silver paste stirring and feeding device.

[0006] The technical implementation scheme of this utility model is as follows: A silver paste mixing and feeding device includes a frame, a material box, a feeding motor, bearing seats, a feeding roller, a first synchronous belt, a rotating plate, a synchronous wheel, a mixing motor, a second synchronous belt, a mixing rod, a coating roller, a third synchronous belt, a coating motor, and a fourth synchronous belt. The material box is installed on the frame, the feeding motor is installed on the frame, bearing seats are symmetrically installed on the left and right sides inside the frame, and a feeding roller is rotatably connected between the two bearing seats. The first synchronous belt is wound between the feeding motor and the right end of the feeding roller. A rotating plate is rotatably connected to each of the two bearing seats, and a synchronous wheel is connected to the outer side of the rotating plate on the right side. The mixing motor is installed on the frame, and a second synchronous belt is wound between the output shaft of the mixing motor and the synchronous wheel. A mixing rod is symmetrically connected vertically between the two rotating plates. Coating rollers are symmetrically rotatably connected front and back inside the frame, and a third synchronous belt is wound between the right ends of the two coating rollers. The coating motor is installed on the frame, and a fourth synchronous belt is wound between the output shaft of the coating motor and the right end of the coating roller on the rear side.

[0007] In a preferred embodiment of this invention, both stirring rods are sharp, angular blades.

[0008] In a preferred embodiment of this invention, multiple blades are connected to both stirring rods.

[0009] In a preferred embodiment of this utility model, the stirring rod, the feeding roller, and the coating roller are each controlled by an independent motor, and their working states can be adjusted according to different needs.

[0010] In a preferred embodiment of this utility model, the outer circle of the feeding roller is provided with multiple rhombuses.

[0011] In a preferred embodiment of this utility model, the frame is provided with multiple strip-shaped mounting slots.

[0012] The beneficial effects of this invention are as follows: This device adopts a double-stirring rod structure. The stirring rods are equipped with sharp blades and stirring blades, which can effectively reduce stirring resistance and significantly improve the mixing efficiency of high-viscosity, low-activity silver paste. This allows the silver paste to reach the ideal active state required for coating and printing more quickly, thereby improving production efficiency. Simultaneously, the outer circumference of the feeding roller adopts a diamond-pattern design, which can accurately and evenly deliver the bottom paste to the surface of the coating roller. Combined with the transmission system of the coating roller, a highly efficient and orderly paste processing flow is formed, ensuring the continuity and stability of the entire process. Each key component—stirring rod, feeding roller, and coating roller—is driven by an independent motor. The coating roller is controlled by a dedicated motor and synchronous belt. This independent power control system can flexibly adjust the speed and operating status of each component according to the characteristics of different silver pastes and process requirements, greatly improving the applicability and operational flexibility of the equipment. Through efficient processing of the silver paste, this device significantly improves the uniformity and stability of subsequent coating and printing, helping to improve the quality and performance of photovoltaic products, reduce the defect rate, and has good application value.

Detailed Implementation

[0020] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0021] Example: A silver paste mixing and feeding device, such as Figures 1-6As shown, the machine includes a frame 1, a material box 2, a feeding motor 3, a bearing seat 4, a feeding roller 5, a first synchronous belt 6, a rotating plate 7, a synchronous pulley 8, a stirring motor 9, a second synchronous belt 10, a stirring rod 11, a coating roller 12, a third synchronous belt 13, a coating motor 14, and a fourth synchronous belt 15. The frame 1 has multiple strip-shaped mounting slots to facilitate the installation of multiple motors. The material box 2 is installed on the frame 1 to hold silver paste or other pastes to be processed, providing material storage space for subsequent feeding and coating operations. A feeding motor 3 is installed on the frame 1. Bearing seats 4 are symmetrically installed on the left and right sides inside the frame 1. A feeding roller 5 is rotatably connected between the two bearing seats 4. It is responsible for evenly conveying the slurry at the bottom of the material box 2 to the surface of the coating roller 12 above. The outer circle of the feeding roller 5 has multiple rhomboids to enhance the gripping ability of high viscosity slurry and improve the feeding efficiency and uniformity. A first synchronous belt 6 is wound between the feeding motor 3 and the right end of the feeding roller 5. A rotating plate 7 is rotatably connected to each of the two bearing seats 4. The outer side of the rotating plate 7 on the right side is connected to a synchronous belt. A stirring motor 9 is installed on the frame 1, and a second synchronous belt 10 is wound between the output shaft of the stirring motor 9 and the synchronous wheel 8. A stirring rod 11 is symmetrically connected between the two rotating plates 7, directly stirring the silver paste in the material box 2, breaking up clumps, dispersing particles, and promoting the homogenization of the paste. Both stirring rods 11 are sharp blade-shaped to reduce stirring resistance and improve the mixing efficiency of high-viscosity paste. Multiple blades are connected to both stirring rods 11 to enhance the stirring effect, accelerate the formation of the active state of the paste, and improve production efficiency. A coating roller 12 is symmetrically rotated and connected inside the frame 1 to receive the paste conveyed by the feeding roller 5 and evenly coat it on the surface of the target substrate (such as photovoltaic film). The stirring rod 11, feeding roller 5 and coating roller 12 are controlled by independent motors, and the working state can be adjusted according to different needs. A third synchronous belt 13 is wound between the right ends of the two coating rollers 12. A coating motor 14 is installed on the frame 1, and a fourth synchronous belt 15 is wound between the output shaft of the coating motor 14 and the right end of the coating roller on the rear side.

[0022] When using this device, the operator first pours the silver paste into the material box 2. After pouring, the stirring motor 9 is started. The output shaft of the stirring motor 9 drives the rotating plate 7 and the synchronous wheel 8 to rotate via the second synchronous belt 10. The rotating plate 7 drives the two stirring rods 11 to rotate synchronously, thereby stirring the silver paste in the material box 2. Because the stirring rods 11 are designed with sharp blades and equipped with blades, they can effectively reduce stirring resistance and improve the mixing efficiency of high-viscosity, low-activity silver paste, allowing the silver paste to reach the ideal active state required for coating and printing more quickly, thereby improving overall production efficiency. After stirring is completed, the stirring motor 9 is turned off. Then, the coating motor 14 is started, and its output shaft drives the rear coating roller 12 to rotate through the fourth synchronous belt 15. At the same time, it drives the front coating roller 12 to rotate synchronously through the third synchronous belt 13. Then, the feeding motor 3 is started, and its output shaft drives the feeding roller 5 to rotate through the first synchronous belt 6. The feeding roller 5 can accurately deliver the bottom slurry to the surface of the coating roller 12. Together with the transmission system of the coating roller 12, a set of efficient and stable slurry processing flow is formed to ensure the continuity and uniformity of the silver paste throughout the process. After the coating roller 12 completes the coating operation, the feeding motor 3 and the coating motor 14 are turned off in sequence, and the entire operation process ends.
