Description

Technical Field

[0001] The utility model relates to the technical field of electronic silver paste feeding components, in particular to a feeding mechanism for preparing electronic silver paste. Background Art

[0002] Electronic silver paste is a conductive material used in the electronics industry. It is mainly composed of silver powder, glass frit, organic carrier and other ingredients. It is used as a conductive adhesive or conductive coating in many applications, such as in solar cells, touch screens, printed circuit boards and other electronic products that require conductive paths.

[0003] The existing announcement number is CN206595085U, and its name is a silver paste preparation device with uniform feeding, including a storage box with four vertical partitions. The partitions divide the storage box into five storage cavities. The five storage cavities store resin, silver powder, curing agent, curing accelerator and defoaming agent respectively. A discharge pipe is connected to the bottom of each storage cavity, and the five discharge pipes are all connected to the connecting pipe. A plurality of feed pipes are connected to the end of the connecting pipe; it also includes a reactor, and a plurality of feed pipes are extended into the top of the reactor and are evenly distributed on the top of the reactor. An outlet is provided at the bottom of the reactor, and a valve is provided at the outlet. A slurry storage tank is connected to the bottom of the outlet, and a screen is provided between the outlet and the slurry storage tank; a horizontal stirring shaft is provided in the reactor, and a plurality of stirring blades are connected to the stirring shaft, which can feed the material evenly so that the materials are fully stirred and mixed to meet the production requirements of the silver paste, improve production efficiency and save manpower labor. At the same time, the slurry that meets the requirements can be screened out, while the slurry that does not meet the requirements will continue to be prepared in the device.

[0004] However, when adding materials to the silver paste preparation, multiple feeding pipes are set on the connecting pipe, and the reactor is dispersedly fed with materials through the multiple feeding pipes. However, there is a lack of pushing components on the connecting pipe, and the material pushing movement is solely relied on, resulting in the silver paste preparation powder being unable to move evenly to multiple feeding pipes for falling, thereby affecting the silver paste preparation feeding efficiency.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0023] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

The top end of the mixing barrel 1 is open, and the barrel cover 2 is assembled at the open end of the mixing barrel 1. A feeding piece 21 is provided on the barrel cover 2. The feeding piece 21 includes a distribution rod ring 211. The distribution rod ring 211 is fixed on the barrel cover 2, and a plurality of feeding pipes are vertically connected and fixed on the bottom surface of the distribution rod ring 211.

When in use, the barrel cover 2 is assembled to the opening of the mixing barrel 1. At the end, when feeding, the materials for preparing the electronic silver paste are added to the storage barrel 213, and the conveying air pump 214 on the air inlet pipe 212 is started to drive air into the air inlet pipe 212. The air carries the materials for preparing the electronic silver paste in the air inlet pipe 212 into the distribution rod ring 211, and then enters the mixing barrel 1 through multiple feeding pipes, so that a pneumatic pushing component is set in the air inlet pipe 212 of the feeding part 21, and the material is driven to move by pneumatic pushing, enters the distribution rod ring 211, and is dispersed into the mixing barrel 1 through multiple feeding pipes, ensuring that the silver paste preparation powder moves evenly to multiple feeding pipes for falling, thereby improving the transportation rate of the electronic silver paste preparation materials, thereby improving the silver paste preparation feeding efficiency.

[0027] In one embodiment, Figure 4 and 5 As shown, a mesh ring 24 is fixed horizontally through the barrel cover 2, and a cloth ring 25 is fixed on the bottom surface of the mesh ring 24.
