Abstract
Description
Technical Field
[0001] This utility model relates to the field of conductive paste preparation technology, and more specifically to a device for making conductive paste. Background Technology
[0002] Conductive paste, also known as conductive adhesive, is a mixture of precious metal powder, base metal powder, glass powder, and synthetic resin. Adding solvents can produce a paste or graphite-like substance. Conductive paste is a material formed by uniformly adding conductive powder to a binder and then curing it to form a conductor. It is used in the formation of electronic circuits, electrode formation of electronic components, lead wire extension, and circuit connection formation. Conductive pastes are broadly classified into high-temperature winding type (using glass powder in the binder), low-temperature sintering type (using synthetic resin binders), and UV-cured type (cured by ultraviolet light).
[0003] In traditional equipment, the shape and layout of the mixing blades are often unreasonable, leading to uneven mixing. When conveying conductive slurries containing large particles or fibrous additives, these substances are prone to clogging at pipe bends or diameter changes. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3This utility model provides a technical solution: a conductive paste preparation device, comprising: a paste holding tank 1, a support frame 2 fixedly installed around the paste holding tank 1, a surrounding plate 3 on the top of the paste holding tank 1, and a sealing cover 4 on the upper part of the surrounding plate 3, the surrounding plate 3 and the sealing cover 4 being fixedly connected, and the sealing cover 4 being sleeved on the surface of the paste holding tank 1 through the surrounding plate 3, a driver 5 being provided on the surface of the sealing cover 4, and a drive shaft 13 being provided at the power output end of the driver 5, the drive shaft 13 extending into the interior of the paste holding tank 1 and having an upper stirring element 1 provided on its surface. 4. The upper, middle, and lower stirring components 14, 15, and 16 are all welded and fixed to the drive shaft 13. These components are arranged in a spiral structure. The spiral directions of the upper and lower stirring components 14 and 16 are the same, while the spiral direction of the middle stirring component 15 is opposite to that of the upper and lower stirring components 16. A discharge pipe 9 is provided at the bottom of the slurry tank 1, extending outwards. A feed pipe 7 is provided on the side of the slurry tank 1. A surrounding plate 3 is provided at the top of the slurry tank 1. A sealing cover 4 is provided on the upper part of the plate 3. The surrounding plate 3 and the sealing cover 4 are fixedly connected, and the sealing cover 4 is sleeved on the surface of the slurry holding tank 1 through the surrounding plate 3. An actuator 5 is provided on the surface of the sealing cover 4, and a drive shaft 13 is provided at the power output end of the actuator 5. The drive shaft 13 extends into the interior of the slurry holding tank 1 and is provided on its surface with an upper agitator 14, a middle agitator 15, and a lower agitator 16. The upper agitator 14, the middle agitator 15, and the lower agitator 16 are all welded and fixed to the drive shaft 13. The upper agitator 14, the middle agitator 15, and the lower agitator 16 are all arranged in a spiral structure. The upper agitator 14... The spiral directions of the upper and lower agitators 14 and 16 are the same, and the spiral directions of the middle agitator 15 are opposite to those of the upper agitator 14 and 16. When the multi-layered staggered propeller blades rotate, the blades in different layers generate stirring forces in different directions. The upper layer of large-diameter left-handed propeller blades transports the slurry from the edge to the center, while the middle layer of small-diameter right-handed propeller blades spreads the slurry in the center to the surrounding areas. The lower layer of large-diameter left-handed propeller blades gathers the slurry at the edge to the center again. This cycle forms a complex and comprehensive stirring flow field, thereby achieving full mixing of the slurry. A discharge pipe 9 is provided at the bottom of the slurry holding tank 1 and extends outward.
[0019] Further improvements, such as Figure 1 As shown: The outer side of the enclosure 3 is provided with a latch 6 and the enclosure 3 is fixedly connected to the slurry container 1 through the latch 6. The design of the latch 6 enhances the connection stability between the enclosure 3 and the slurry container 1, ensures the sealing performance, and prevents slurry leakage during the mixing process.
[0020] Further improvements, such as Figure 3As shown: A sealing ring 12 is provided on the inner side of the enclosure 3 and the sealing ring 12 is in contact with the slurry holding tank 1. The setting of the sealing ring 12 further improves the sealing performance of the equipment and effectively prevents the slurry from seeping out from the gaps during the mixing process.
[0021] Further improvements, such as Figure 2 As shown: A control valve 8 is provided at the connection between the discharge pipe 9 and the slurry holding tank 1. The addition of the control valve 8 makes the discharge process more controllable, and the discharge speed and amount of slurry can be adjusted according to production needs.
[0022] Further improvements, such as Figure 1 As shown: The surface of the discharge pipe 9 is provided with a mounting base 10 and the surface of the mounting base 10 is provided with a vibration motor 11. The vibration motor 11 can effectively prevent the slurry from clogging in the discharge pipe 9. In particular, when the slurry contains large particles or fibrous additives, vibration can help these substances pass through the pipe smoothly, ensuring the continuity and stability of production.
[0023] Further improvements, such as Figure 1 As shown: The bottom of the slurry container 1 is designed with a conical structure. The conical bottom design facilitates the discharge of slurry, reduces slurry residue at the bottom of the container, and improves the utilization rate of slurry.
[0024] Working Principle: The original straight-blade impeller agitator is replaced with a multi-layered staggered propeller agitator. Specifically, the top layer consists of large-diameter left-handed propeller blades, the middle layer of small-diameter right-handed propeller blades, and the bottom layer of large-diameter left-handed propeller blades again. As these multiple layers of staggered propeller blades rotate, they generate stirring forces in different directions. The upper layer of large-diameter left-handed propeller blades transports the slurry from the edge to the center, the middle layer of small-diameter right-handed propeller blades diffuses the slurry from the center outwards, and the bottom layer of large-diameter left-handed propeller blades again gathers the slurry from the edge towards the center, forming a complex and comprehensive stirring flow field. The conveying pipe is designed with a smooth inner wall and an automatic vibration device. Embedded vibration generators are installed at bends and diameter changes in the pipeline. The vibration generated by the vibration motor 11 resuspends particles or fibrous materials adhering to the inner wall of the pipeline or accumulating at bends and diameter changes in the slurry, allowing them to flow with the slurry. The vibration frequency and amplitude can be adjusted by an external controller to adapt to the conveying needs of conductive slurries with different properties. The truncated cone structure at the bottom allows the slurry to naturally converge towards the central outlet under gravity. Compared to a cylindrical bottom, the truncated cone structure reduces the contact area between the slurry and the bottom of the container, reducing the possibility of slurry residue. The cone angle design optimizes the gravity flow effect, ensuring smoother slurry discharge.
