[0002] With the continuous development of the electronic component manufacturing field, conductive silver paste, as an important material, is widely used in printed circuit boards, solar cells, and other fields. However, the preparation process of conductive silver paste is often accompanied by the presence of particles and impurities, which may affect the conductivity and quality of the material. Especially in high-power electronic components, the purity and uniformity of conductive silver paste are crucial to the performance of the components.

[0003] In existing technologies, conductive silver paste filtration and separation equipment filters conductive silver paste using filter plates. However, this only serves a filtering function and cannot fully mix the conductive silver paste during filtration. Furthermore, the filter plates are mostly fixed to the filtration and separation equipment with bolts, making it inconvenient to quickly remove and clean them when there are many impurities. Therefore, it is necessary to design a continuous conductive silver paste filtration and separation equipment to solve the above problems.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a continuous filtration and separation device for conductive silver paste, comprising:

[0031] The conductive silver paste mixing box 1 is equipped with a mixing and cleaning mechanism. It should be noted that this mechanism facilitates the thorough mixing of the conductive silver paste during continuous filtration and separation, and also facilitates the quick cleaning of impurities on the filter plate.

[0032] The mixing and cleaning mechanism includes a placement tank 2, a support block 4, a coarse filter plate 5, a connector 6, a fine filter plate 7, a material pump 8, a discharge pipe 9, a rotating pipe 10, a cover plate 11, and a servo motor 14.

[0033] The placement bucket 2 is fixedly installed on the top of the conductive silver paste mixing box 1. The support block 4 is clamped to the placement bucket 2. The bottom of the support block 4 is fixedly connected to the coarse filter plate 5. The connector 6 is fixedly installed between the coarse filter plate 5 and the fine filter plate 7. It should be noted that this is how the conductive silver paste is filtered in multiple stages.

[0034] The pump 8 is fixedly installed on the top of the conductive silver paste mixing tank 1. The discharge pipe 9 is fixedly connected to the pump 8. The rotating pipe 10 is rotatably connected to the discharge pipe 9 through a sealed bearing. The cover plate 11 is fixedly connected to the rotating pipe 10. The output end of the servo motor 14 is fixedly connected to the rotating pipe 10.

[0035] With the above structure, conductive silver paste is added through the conductive silver paste addition hopper 19. The coarse filter plate 5 and the fine filter plate 7 can filter the conductive silver paste. The filtered conductive silver paste enters the conductive silver paste mixing tank 1. After the conductive silver paste is added, the pump 8 is started to extract the conductive silver paste, which then enters the placement tank 2 through the discharge pipe 9 and the rotating pipe 10. In this back-and-forth circulation process, the conductive silver paste can be continuously filtered and separated, and the conductive silver paste can also be initially mixed evenly. After the mixing and filtration are completed, when it is necessary to clean the impurities on the coarse filter plate 5 and the fine filter plate 7, the servo motor 14 is started, which can make the rotating pipe 10 drive the cover plate 11 to rotate, so that the cover plate 11 is separated from the support block 4. At this time, the support block 4 is pulled upward to quickly remove the support block 4, which facilitates the quick removal and cleaning of the coarse filter plate 5 and the fine filter plate 7.

[0036] Specifically, the mixing and cleaning mechanism also includes a feed pipe 15, a mixing component 16, and a paddle 17. The feed pipe 15 is fixedly installed on the pump 8 and the conductive silver paste mixing tank 1. The mixing component 16 is rotatably installed on the feed pipe 15, and the paddle 17 is fixedly installed on the mixing component 16.

[0037] With the above structure, when the pump 8 is working, the conductive silver paste will impact the blade 17, causing the mixing component 16 to rotate, which can further agitate the conductive silver paste and make it more uniformly mixed.

[0038] Specifically, a feeding pipe 18 is fixedly installed on the placement bucket 2, and a conductive silver paste adding hopper 19 is fixedly installed on the cover plate 11. It should be noted that this is to facilitate the addition of conductive silver paste.

[0039] Specifically, the top of the placement bucket 2 is provided with a bearing groove 3, the bearing block 4 is engaged with the bearing groove 3, and the bottom of the cover plate 11 is in contact with the placement bucket 2 and the bearing block 4. It should be noted that the bearing block 4 can be limited.

[0040] Specifically, a stabilizing element 12 is fixedly installed between the rotating tube 10 and the cover plate 11. It should be noted that this element improves the stability between the rotating tube 10 and the cover plate 11.

[0041] Specifically, a support 13 is fixedly installed on the top of the conductive silver paste mixing box 1, and a servo motor 14 is fixedly installed on the top of the support 13. It should be noted that this is to facilitate the assembly of the servo motor 14.

[0042] Working principle:

[0043] S1: The conductive silver paste is poured from the conductive silver paste addition hopper 19 on the cover plate 11 into the placement tank 2. Since the top of the placement tank 2 is provided with a support groove 3, the support block 4 is locked to the support groove 3, and the bottom of the support block 4 is fixedly connected to the coarse filter plate 5. The coarse filter plate 5 and the fine filter plate 7 are fixedly connected by the connector 6. Therefore, under the action of gravity, the conductive silver paste passes through the coarse filter plate 5 and the fine filter plate 7 in sequence to achieve preliminary multi-stage filtration. Larger impurities are intercepted by the coarse filter plate 5, and smaller particles and some impurities are further filtered by the fine filter plate 7. The filtered conductive silver paste flows into the conductive silver paste mixing box 1 through the feed pipe 18 on the placement tank 2.

[0044] S2: After the conductive silver paste is added, start the pump 8 fixedly installed on the top of the conductive silver paste mixing tank 1. The pump 8 draws out the conductive silver paste from the conductive silver paste mixing tank 1 through the feed pipe 15. When the conductive silver paste passes through the feed pipe 15, it impacts the blades 17 fixedly installed on the mixing component 16, causing the mixing component 16 to rotate on the feed pipe 15, thus initially agitating and mixing the conductive silver paste. Subsequently, the conductive silver paste returns to the placement tank 2 through the discharge pipe 9 and the rotating pipe 10 rotatably connected to the discharge pipe 9 through the sealed bearing, thus forming a cycle. During the cycle, the conductive silver paste continuously passes through the coarse filter plate 5 and the fine filter plate 7 to achieve continuous filtration and separation. At the same time, under the action of the blades 17 in the feed pipe 15 and the circulating flow, the conductive silver paste is also fully mixed to ensure its uniformity.

[0045] S3: When there are many impurities accumulated on the coarse filter plate 5 and the fine filter plate 7, and cleaning is required, start the servo motor 14 fixedly installed on the top of the support 13. The output end of the servo motor 14 drives the rotating tube 10 to rotate. The rotating tube 10 drives the cover plate 11 to rotate through the stabilizer 12, so that the cover plate 11 is separated from the support block 4, and the limit on the support block 4 is released. At this time, pull the support block 4 upward. Since the support block 4 is locked with the support groove 3 of the placement tank 2, the support block 4 can be quickly removed. Then, the coarse filter plate 5 and the fine filter plate 7 connected to the support block 4 can be removed together, which makes it convenient to clean the impurities on the filter plates. After cleaning, the support block 4 is locked back into the support groove 3, and the servo motor 14 is started to reverse, so that the cover plate 11 is reset and the support block 4 is locked again. The equipment can then be put into use again.

Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
