Description

Technical Field

[0001] This utility model relates to the field of silver paste dispersion technology, specifically a mechanism for uniformly dispersing solar silver paste. Background Technology

[0002] With the rapid development of solar energy technology, the production scale of solar cells is constantly expanding, and their manufacturing processes are becoming increasingly refined. Solar silver paste, as a key conductive material, is widely used in the electrode preparation process of solar cells. The quality and dispersion uniformity of the silver paste directly affect the electrode performance, photoelectric conversion efficiency, and product reliability of solar cells.

[0003] In traditional solar silver paste preparation processes, simple stirring equipment or manual stirring is typically used to disperse the silver paste. While these methods can disperse the particles in the silver paste to some extent, they have the following significant problems:

[0004] Uneven dispersion: Traditional stirring methods cannot ensure that the particles in the silver paste are completely and evenly distributed, which can easily lead to agglomeration. This results in unstable conductivity of the silver paste and affects the performance of solar cells.

[0005] Inefficient: Manual mixing or simple mechanical mixing is inefficient and cannot meet the needs of large-scale production, increasing production costs and time.

[0006] Therefore, a mechanism for uniformly dispersing solar silver paste is needed to improve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a mechanism for uniformly dispersing solar silver paste to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A solar silver paste uniform dispersion mechanism includes a housing, a slide rail fixedly mounted on the upper end of the housing, a plurality of sliders slidably mounted on the lower surface of the slide rail, an mounting plate fixedly mounted on the lower end of the sliders, a mesh dispersion cylinder fixedly mounted on the lower end of the mounting plate, a lifting cylinder fixedly mounted on the lower end of the mesh dispersion cylinder, a feed inlet fixedly mounted on the upper end of the housing, a funnel-shaped bottom of the housing, and a transmission mechanism mounted on the upper end of the housing.

[0010] As a preferred embodiment of this utility model, the transmission mechanism includes a motor, and a stirring shaft is driven at the output end of the motor. Several stirring rods are fixedly arranged on the surface of the stirring shaft, and the stirring rods are arranged inside the mesh dispersion cylinder.

[0011] As a preferred embodiment of this utility model, the lower end side surface of the lifting cylinder is provided with a plurality of through grooves, and a spiral blade is fixedly provided on the inner side of the through grooves corresponding to the surface of the stirring shaft.

[0012] As a preferred embodiment of this utility model, a hollow discharge shaft is fixedly provided at the bottom of the lower end of the lifting cylinder, and a valve is fixedly provided on the surface of the hollow discharge shaft.

[0013] As a preferred embodiment of this utility model, the transmission mechanism further includes gear one and gear two, which are rotatably mounted inside the cover via a connecting shaft.

[0014] As a preferred embodiment of this utility model, a third gear is fixedly provided on the surface of the stirring shaft, which meshes with a second gear. An annular meshing groove is fixedly provided on the upper end of the mounting plate, which meshes with a first gear.

[0015] As a preferred embodiment of this utility model, the slide rail is arranged in a ring shape, and the slide rail and the ring meshing groove are the same as the axis of the stirring shaft.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model adopts a combination of spiral blade lifting and centrifugal discharge from a mesh dispersing cylinder to perform multi-stage dispersion treatment of silver paste. First, the silver paste is lifted and initially mixed by the spiral blade. Then, the centrifugal action of the mesh dispersing cylinder is used to further refine the particles and ensure the uniformity of the silver paste. This multi-stage dispersion method can effectively break the agglomeration of silver paste particles, making the particles in the silver paste more evenly distributed and significantly improving the dispersion effect of the silver paste.

[0018] 2. The silver paste dispersion process is automated through motor drive and valve control, reducing human intervention and improving production efficiency. Operators only need to start the motor and control the valves to complete the dispersion and discharge of silver paste, greatly simplifying the operation process. The spiral blade design can quickly lift the silver paste from the bottom to the top of the lifting cylinder, achieving initial mixing during the lifting process. The centrifugal effect of the mesh dispersion cylinder further refines the silver paste particles. The entire dispersion process is efficient and continuous, significantly shortening the time required for silver paste dispersion. Attached Figure Description

[0031] Please see Figure 1-7 This utility model provides a technical solution: a solar silver paste uniform dispersion mechanism, including a shell 5, a slide rail 12 fixedly installed at the upper end of the shell 5, a plurality of sliders 13 slidably installed on the lower surface of the slide rail 12, an installation plate 18 fixedly installed at the lower end of the sliders 13, a mesh dispersion cylinder 6 fixedly installed at the lower end of the installation plate 18, a lifting cylinder 8 fixedly installed at the lower end of the mesh dispersion cylinder 6, a feed inlet 2 fixedly installed at the upper end of the shell 5, a funnel-shaped bottom of the shell 5, a transmission mechanism 1 installed at the upper end of the shell 5, a motor 17 in the transmission mechanism 1 starts to work, its output end drives the stirring shaft 3 to rotate, the rotation of the stirring shaft 3 drives the spiral blades 7 to rotate, a plurality of through grooves 10 are provided on the lower side surface of the lifting cylinder 8, the silver paste enters the lifting cylinder 8 through the through grooves 10, and the spiral blades 7 lift the silver paste in the lifting cylinder 8 upward along the lifting cylinder 8 through their spiral structure and enter the mesh dispersion cylinder 6.

[0032] As an example of this utility model, the transmission mechanism 1 includes a motor 17, and the output end of the motor 17 is equipped with a stirring shaft 3. Several stirring rods 4 are fixedly arranged on the surface of the stirring shaft 3. The stirring rods 4 are arranged inside the mesh dispersion cylinder 6. As the stirring shaft 3 rotates, the stirring rods 4 perform preliminary stirring on the silver paste entering the mesh dispersion cylinder 6, so that the silver paste begins to flow and mix in the cylinder, breaking the initial agglomeration state of the silver paste and creating conditions for subsequent dispersion operations.

[0033] As an example of this utility model, the lower end side surface of the lifting cylinder 8 is provided with a plurality of through grooves 10, and the inner side of the through grooves 10 is fixedly provided with spiral blades 7 corresponding to the surface of the stirring shaft 3.

[0034] As an example of this utility model, a hollow discharge shaft 9 is fixedly provided at the bottom of the lower end of the lifting cylinder 8, and a valve is fixedly provided on the surface of the hollow discharge shaft 9.

[0035] As an example of this utility model, the transmission mechanism 1 also includes a first gear 14 and a second gear 15, which are rotatably disposed inside the cover 11 via a connecting shaft.

[0036] As an example of this utility model, a gear 3 16 is fixedly provided on the surface of the stirring shaft 3, and the gear 3 16 meshes with the gear 2 15. An annular meshing groove 19 is fixedly provided on the upper end of the mounting plate 18, and the annular meshing groove 19 meshes with the gear 1 14. Meanwhile, an annular meshing groove 19 is fixedly provided on the upper end of the mounting plate 18, and the annular meshing groove 19 meshes with the gear 1 14.

[0037] This causes the mounting plate 18 to rotate and slide on the surface of the slide rail 12 via the slider 13, thereby causing the mesh dispersion cylinder 6 to rotate and centrifugally throw out the silver paste inside for further dispersion. After completion, the hollow discharge shaft 9 is opened, and the silver paste after lifting and dispersion is finally discharged through the hollow discharge shaft 9.

[0038] As an example of this utility model, the slide rail 12 is arranged in a ring, and the slide rail 12 and the annular meshing groove 19 are the same as the axis of the stirring shaft 3.

[0039] Working principle: When in use, the motor 17 in the transmission mechanism 1 starts to work, and its output end drives the stirring shaft 3 to rotate. The rotation of the stirring shaft 3 drives the spiral blade 7 to rotate. The lower side surface of the lifting cylinder 8 is provided with several through grooves 10. The silver paste enters the lifting cylinder 8 through the through grooves 10. The spiral blade 7 lifts the silver paste in the lifting cylinder 8 upward along the lifting cylinder 8 through its spiral structure and enters the mesh dispersion cylinder 6.

[0040] Several stirring rods 4 are fixed on the surface of the stirring shaft 3. These stirring rods 4 are located inside the mesh dispersion cylinder 6. As the stirring shaft 3 rotates, the stirring rods 4 initially stir the silver paste entering the mesh dispersion cylinder 6, so that the silver paste begins to flow and initially mix in the cylinder, breaking the initial agglomeration state of the silver paste and creating conditions for subsequent dispersion operations.

[0041] Gear 3 16 is fixedly mounted on the surface of the stirring shaft 3, and gear 3 16 meshes with gear 2 15. At the same time, an annular meshing groove 19 is fixedly mounted on the upper end of the mounting plate 18, and the annular meshing groove 19 meshes with gear 1 14.

[0042] This causes the mounting plate 18 to rotate and slide on the surface of the slide rail 12 via the slider 13, thereby causing the mesh dispersion cylinder 6 to rotate and centrifugally throw out the silver paste inside for further dispersion. After completion, the hollow discharge shaft 9 is opened, and the silver paste after lifting and dispersion is finally discharged through the hollow discharge shaft 9.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
