Description

Technical Field

[0001] This utility model relates to the field of storage technology, and in particular to a conductive silver paste filtration and storage device. Background Technology

[0002] Conductive silver paste is a paste-like conductive material containing silver particles, organic carriers, and other components. It is applied to the surface of a substrate through coating, printing, or other methods, and forms conductive lines or electrodes after drying or curing. It has good conductivity and adhesion and is widely used in electronic devices, photovoltaic cells, flexible circuits, and other fields to achieve electrical connection functions. After the conductive silver paste is produced, it needs to be stored in a container and sealed with a lid. When it is needed, the lid is removed and the conductive silver paste in the container is poured out.

[0003] When conductive silver paste is stored for a long time, the silver particles and organic carriers in its components may settle and aggregate due to solvent evaporation, temperature and humidity changes, or gravity, leading to a decrease in system stability and the formation of clumps, which affects the quality of subsequent coating or printing. Therefore, this application provides a conductive silver paste filtration and storage device to meet the requirements. Summary of the Invention

[0004] This invention provides a conductive silver paste filtration and storage device to solve the problem that the agglomeration of conductive silver paste affects the quality of subsequent coating or printing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A conductive silver paste filtration and storage device includes a barrel body and a barrel cover threaded onto the top of the barrel body, and further includes:

[0007] The discharge hole is located at the bottom of the inner wall of the barrel. An external threaded ring is fixed at the bottom of the barrel and at the discharge hole. A filter plate is fixed on the inner wall of the discharge hole. A cap is threadedly connected to the surface of the external threaded ring. A pressure plate is slidably connected to the inner wall of the barrel.

[0008] When removing the conductive silver paste, open the bucket lid and the sealing cap, press the pressure plate, and the conductive silver paste will be filtered by the filter plate and discharged from the discharge hole.

[0009] Preferably, an aluminum foil sealing film is fixed to the bottom of the external threaded ring, and the cover is placed over the aluminum foil sealing film.

[0010] Preferably, the surface of the external threaded ring is provided with a flat groove, and the aluminum foil sealing film is provided with a tear-off part at the flat groove. After the cap is screwed on, the tear-off part adheres to the surface of the flat groove.

[0011] Preferably, the end of the tearing part is provided with a protrusion.

[0012] Preferably, the bottom of the pressure plate is provided with a first inclined surface, and the bottom of the inner wall of the barrel is provided with a second inclined surface. The first and second inclined surfaces correspond to each other, and both the first and second inclined surfaces are used to guide the conductive silver paste to flow towards the discharge hole.

[0013] Preferably, the surface of the cap is provided with anti-slip stripes.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, by setting up a discharge hole, a pressure plate, and a filter plate, when the conductive silver paste needs to be removed, the pressure inside the barrel is increased by pressing the pressure plate, and the conductive silver paste will be discharged from the discharge hole at the bottom of the barrel. During the discharge process, the conductive silver paste will pass through the filter plate, and the filter plate will remove the clumps in the conductive silver paste, thereby ensuring the quality of subsequent coating or printing.

[0016] By setting up inclined plane one and inclined plane two, inclined plane two can guide the conductive silver paste, allowing it to flow smoothly out of the discharge hole. When inclined plane one and inclined plane two are close together, inclined plane one will cooperate with inclined plane two to guide the conductive silver paste, avoiding the presence of conductive silver paste residue inside the tank and preventing waste of conductive silver paste.

[0017] By setting an aluminum foil sealing film, the discharge hole can be sealed more thoroughly. Secondly, after tearing off the aluminum foil sealing film, the conductive silver paste on the aluminum foil sealing film can be scraped off directly, thus avoiding the waste of conductive silver paste.

[0018] By setting up a tear-off section and a flat groove, after the cap is screwed onto the discharge hole, the tear-off section is housed in the flat groove. When it is necessary to tear open the aluminum foil seal, the tear-off section can provide a larger contact area for the hand, making it easier for the hand to exert force and tear off the aluminum foil seal.

[0019] By adding protrusions, the friction between the tearing part and the hand can be increased, preventing the hand from slipping off the tearing part and improving stability during tearing. Attached Figure Description

According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0027] The conductive silver paste filtering and storage device provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0028] like Figures 1-5 As shown, an embodiment of this utility model provides a conductive silver paste filtration and storage device, including a barrel body 1 and a barrel cover 2 threadedly installed on the top of the barrel body 1, and further including:

[0029] Discharge hole 4 is located at the bottom of the inner wall of barrel 1. An external threaded ring is fixed at the bottom of barrel 1 and at discharge hole 4. A filter plate 5 is fixed on the inner wall of discharge hole 4. A cap 6 is threadedly connected to the surface of the external threaded ring. A pressure plate 3 is slidably connected to the inner wall of barrel 1.

[0030] When removing the conductive silver paste, open the bucket lid 2 and the sealing cap 6, press the pressure plate 3, and the conductive silver paste will be filtered by the filter plate 5 and discharged from the discharge hole 4. The discharge hole 4, filter plate 5, sealing cap 6 and pressure plate 3 work together to realize the storage, filtration and use of conductive silver paste. The pressure plate 3 increases the internal pressure of the bucket 1 by pressing, so that the conductive silver paste flows in a directional manner. The filter plate 5 intercepts the lumps in the conductive silver paste to ensure that the discharged silver paste has a uniform texture and improves the quality of subsequent coating or printing. The sealing cap 6 cooperates with the external threaded ring to seal the discharge hole 4 when not in use to prevent the silver paste from drying out, becoming contaminated or leaking. The bucket lid 2 is threaded to the bucket 1 to further ensure the airtightness of the device and maintain a stable silver paste storage environment.

[0031] like Figures 2-5As shown in this embodiment, an aluminum foil sealing film 7 is fixed at the bottom of the external threaded ring, and a cover 6 covers the aluminum foil sealing film 7. The aluminum foil sealing film 7 provides a secondary seal for the discharge hole 4. Compared with a single cover 6, it has stronger sealing performance and can effectively isolate air and moisture, preventing the conductive silver paste from deteriorating due to oxidation, moisture and other factors during storage.

[0032] like Figure 4 and Figure 5 As shown in this embodiment, a flat groove 10 is provided on the surface of the external threaded ring. A tear-off part 8 is provided at the flat groove 10 of the aluminum foil sealing film 7. After the cap 6 is screwed on, the tear-off part 8 adheres to the surface of the flat groove 10. The flat groove 10 provides storage space for the tear-off part 8. When the cap 6 is screwed on, the tear-off part 8 adheres to the flat groove 10 to avoid accidental scratches or damage due to protrusion. When silver paste needs to be taken out, the tear-off part 8 makes it easy for the operator to quickly position and apply pulling force. Its large contact area can disperse the hand force, reduce the difficulty of tearing the aluminum foil sealing film 7, make the operation more labor-saving and efficient, and reduce the risk of incomplete tearing of the aluminum foil sealing film 7 and leakage of silver paste due to improper tearing.

[0033] like Figure 5 As shown in this embodiment, the tearing part 8 is provided with a protrusion 9 at its end. The protrusion 9 increases the contact friction between the tearing part 8 and the hand, preventing the hand from slipping or detaching when tearing the aluminum foil seal 7, thus improving operational stability and success rate. Especially when the hand is wet or contaminated with silver paste, which reduces friction, the protrusion 9 can significantly enhance the gripping effect, ensuring that the aluminum foil seal 7 can be torn open completely in one go, reducing the time the silver paste is exposed to the air, and maintaining its performance stability.

[0034] like Figure 2 As shown in this embodiment, the bottom of the pressure plate 3 is provided with a first inclined surface 11, and the bottom of the inner wall of the barrel 1 is provided with a second inclined surface 12. The first inclined surface 11 and the second inclined surface 12 correspond to each other. Both the first inclined surface 11 and the second inclined surface 12 are used to guide the conductive silver paste to flow towards the discharge hole 4. The first inclined surface 11 and the second inclined surface 12 form a flow guiding structure. When the pressure plate 3 is pressed, the conductive silver paste is squeezed and flows along the inclined surface, effectively preventing the silver paste from remaining in the corner of the barrel 1. The inclined surface design reduces the flow resistance of the silver paste, making it more smoothly converge towards the discharge hole 4 and improving the utilization efficiency. At the same time, when the pressure plate 3 is pressed down to the limit position, the two inclined surfaces fit together, which can maximize the discharge of the silver paste in the barrel, reduce waste, and improve the material utilization rate.

[0035] like Figure 2As shown in this embodiment, the surface of the cap 6 is provided with anti-slip stripes. The anti-slip stripes increase the roughness of the surface of the cap 6, which can effectively increase the friction between the hand and the cap 6 when the cap 6 is turned to open or close, preventing the hand from slipping and ensuring safe and stable operation. Especially when the hand is covered with silver paste or in a humid environment, the anti-slip stripes can significantly improve the grip, making it easier and more accurate for the operator to control the tightening degree of the cap 6, ensuring the sealing effect of the discharge hole 4, and preventing silver paste leakage or the entry of external impurities.

[0036] Working principle: When using the conductive silver paste filtration and storage device, first check whether the cover 6 is tightened and whether the aluminum foil sealing film 7 is completely sealed to the discharge hole 4 to ensure that the conductive silver paste is in a sealed storage state.

[0037] When it is necessary to remove the conductive silver paste, first unscrew the bucket cap 2, then unscrew the sealing cap 6, and then tear off the aluminum foil sealing film 7. When tearing, you can grasp the protrusion 9 of the tearing part 8 and use its increased friction to tear off the aluminum foil sealing film 7.

[0038] Then, place your hand on the pressure plate 3 and press down. The inclined surface 11 at the bottom of the pressure plate 3 and the inclined surface 12 at the bottom of the inner wall of the barrel 1 cooperate with each other to guide the conductive silver paste to flow to the discharge hole 4. During the pressing process, the pressure inside the barrel 1 increases, forcing the conductive silver paste to pass through the filter plate 5. The filter plate 5 intercepts the clumps in the conductive silver paste, and the filtered conductive silver paste is discharged from the discharge hole 4.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
