Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic potting glue, in particular to a preparation method of low-viscosity high-thermal-conductivity potting glue for induction cooker panel. BACKGROUND

[0002] Potting glue is mainly used for bonding, sealing, potting and coating protection of electronic components, such as bonding of induction cooker panel. The potting glue is in liquid state and has flowability before curing, and can play the roles of waterproof, moisture-proof, dust-proof, insulation, heat conduction, security, corrosion resistance, temperature resistance and shock resistance after curing.

[0003] There are various preparation methods of low-viscosity high-thermal-conductivity potting glue in the prior art. In the preparation method using long-chain alkyl silicone oil and vinyl silicone oil as raw materials, the long-chain alkyl silicone oil and the vinyl silicone oil are stirred at room temperature, mixed uniformly, then heated and stirred with the addition of aluminum oxide filler, and stirred again after mixing uniformly, and then vacuumized and stirred with the addition of platinum catalyst.

[0004] However, the above preparation method still has some shortcomings after being applied by the person skilled in the art. For example, the standing and cooling process after heating and stirring needs a long time, and after the addition of platinum catalyst, the stirring operation cannot be started until the vacuumizing operation is completed, which consumes a certain amount of time, thus greatly affecting the preparation efficiency of the potting glue product.

[0005] Therefore, it is necessary to invent a preparation method of low-viscosity high-thermal-conductivity potting glue for induction cooker panel to solve the above problems. SUMMARY

[0010] The cooling and mixing mechanism includes a hollow drive screw, a U-shaped stirring tube, a drive motor, and a drive gear;

[0011] The hollow drive screw penetrates the top of the inner cavity of the container and extends to the top of the container, and is rotatably connected to the container through a bearing. Multiple U-shaped stirring tubes are provided, and multiple b are evenly fixedly and permanently installed on both sides of the bottom of the hollow drive screw, and are all connected to the hollow drive screw. Two drive gears are provided, and the hollow drive screw is connected to the drive motor through the two drive gears.

[0012] Preferably, the cooling and vacuuming mechanism includes a first exhaust pipe, a vacuum pump, and a second exhaust pipe.

[0013] Preferably, the first exhaust pipe is fixedly disposed through the middle of the left side of the container, the output end of the first exhaust pipe is fixedly connected to the input end of the vacuum pump, the input end of the second exhaust pipe is fixedly connected to the output end of the vacuum pump, and the output end of the second exhaust pipe is connected to the top end of the hollow drive screw through a rotary joint.

[0014] Preferably, the sealing and feeding mechanism includes a lifting plate, an annular sealing plate, a storage hopper, and a discharge pipe.

[0015] Preferably, the lifting plate is slidably nested inside the container in the vertical direction, the lifting plate is sleeved on the outside of the hollow drive screw and is connected to the hollow drive screw through a reciprocating thread, the annular sealing plate is fixedly installed on the top of the lifting plate and slides against the inner wall of the container, the storage hopper is fixedly installed through the top of the lifting plate and located inside the clearance opening, and the discharge pipe is fixedly connected to the bottom of the storage hopper.

[0016] Preferably, the triggering mechanism includes a fixed rod, a mounting plate, a longitudinal shaft, a first sealing block, and a second sealing block.

[0017] Preferably, the fixing rod is fixedly installed on the top right side of the container, the mounting plate is fixedly installed on the top of the fixing rod, the drive motor and the vacuum pump are both fixedly connected to the mounting plate, the longitudinal shaft is fixedly installed at the bottom of the mounting plate, passes through the storage hopper and the discharge pipe and extends to the bottom of the discharge pipe, the first sealing block and the second sealing block are fixedly sleeved on the outside of the longitudinal shaft from top to bottom, the first sealing block seals the discharge pipe, and both the first sealing block and the second sealing block are slidably installed on the inside of the discharge pipe in the vertical direction.

[0018] Preferably, the preparation method specifically includes the following steps:

[0019] S1. Add the formulated amount of long-chain alkyl silicone oil and vinyl silicone oil into the container through the long-chain alkyl silicone oil inlet pipe and the vinyl silicone oil inlet pipe. Start the drive motor. After the drive motor starts, it drives the hollow drive screw to rotate through the drive gear. When the hollow drive screw rotates, it mixes the long-chain alkyl silicone oil and vinyl silicone oil through multiple U-shaped stirring tubes. During the mixing process, platinum catalyst is added to the inside of the storage hopper through the top opening of the storage hopper.

[0020] S2. After mixing, add the prescribed amount of alumina filler through the feeding hopper. At this time, while the U-shaped stirring tube is mixing the material, the built-in electric heating element inside the container is activated to heat and mix the material.

[0021] S3. Start the vacuum pump. After the vacuum pump starts, it draws air from inside the container through the first exhaust pipe. After the air inside the container is drawn out, outside air enters the container through the feed hopper and continuously exchanges heat with the material through the top surface of the material. At the same time, the vacuum pump draws air into the hollow drive screw through the second exhaust pipe and then enters multiple U-shaped stirring tubes along the hollow drive screw. The air then exchanges heat with the material through the multiple U-shaped stirring tubes, and the material is cooled from the inside.

[0022] S4. During the rotation of the hollow drive screw, the hollow drive screw drives the lifting plate to descend continuously. When the lifting plate descends, it drives the annular sealing plate and the storage hopper to descend synchronously. During the descent of the storage hopper, the longitudinal shaft drives the first sealing block to rise relative to the inside of the feed pipe. When the descent distance of the lifting plate reaches the first threshold, the material is cooled down. At the same time, the lifting plate seals the feed hopper through the annular sealing plate. At this time, outside air cannot enter the container through the feed hopper. The air inside the container is gradually extracted, and the inside of the container is in a negative pressure state.

[0023] S5. When the lifting plate descends to the second threshold, the first sealing block releases the seal on the inside of the feed pipe under the drive of the longitudinal axis. At this time, the platinum catalyst inside the storage hopper quickly passes through the annular channel between the inner wall of the first sealing block and the longitudinal axis and falls into the inside of the container under the influence of the negative pressure inside the container and its own gravity, thereby completing the addition of the platinum catalyst.

[0024] S6. When the lifting plate descends to the third threshold, the platinum catalyst addition is completed. At the same time, the second sealing block enters the inside of the feed pipe under the drive of the longitudinal shaft, and then seals the feed pipe again. At this time, as the vacuum pump continues to work, the inside of the container is gradually evacuated. At this time, multiple U-shaped stirring tubes mix the material under vacuum.

[0025] S7. When the lifting plate descends to the fourth threshold, the lifting plate moves to the lowest end of the reciprocating thread on the outside of the hollow drive screw. Subsequently, as the hollow drive screw continues to rotate, the lifting plate begins to rise and reset along the hollow drive screw. After the lifting plate is completely reset, the mixing is completed, and mixture A is obtained. Mixture A is fed into a container containing mixture B through the discharge pipe for mixing, and a low-viscosity, high-thermal-conductivity potting compound is obtained.

[0026] The technical effects and advantages of this invention are as follows:

[0027] This invention incorporates a cooling and mixing mechanism, a cooling and vacuuming mechanism, a sealing and feeding mechanism, and a triggering mechanism. During the mixing process, the cooling and vacuuming mechanism works in conjunction with the cooling and mixing mechanism to cool the material from both the top surface and the interior, thus improving cooling efficiency. Simultaneously, the mixing process drives the sealing and feeding mechanism to descend continuously, causing it to successively seal the feeding hopper and be triggered by the triggering mechanism. This creates negative pressure inside the container, allowing the platinum catalyst to be fed, accelerating the feeding speed. As the triggering mechanism continues to activate the sealing and feeding mechanism, it eventually seals the hopper again, allowing the cooling and vacuuming mechanism to complete the vacuuming of the container. Compared to similar devices or methods in the prior art, this invention offers a high degree of automation, saves manpower, and effectively shortens the material cooling time, thereby improving the preparation efficiency of the potting compound.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0035] This invention provides, for example Figures 1-5 The invention discloses a method for preparing a low-viscosity, high-thermal-conductivity potting compound for an induction cooker panel. The method is implemented using a potting compound preparation device, which includes a container 1. The container 1 is equipped with a cooling and mixing mechanism 2 inside and a cooling and vacuuming mechanism 3 on the left side of the container 1. The container 1 is equipped with a sealing and feeding mechanism 4 on the top inner side and a triggering mechanism 5 on the top of the container 1. The sealing and feeding mechanism 4 is driven and sleeved on the outside of the cooling and mixing mechanism 2.

[0036] like Figure 3 As shown, the container mechanism 1 includes a container 11, a clearance opening 12, a discharge pipe 13, a feed hopper 14, a long-chain alkyl silicone oil input pipe 15, and a vinyl silicone oil input pipe 16. The clearance opening 12 is located on the top left side of the container 11. The discharge pipe 13 is fixedly installed through the bottom left side of the container 11. The feed hopper 14 is fixedly nested in the top right side of the container 11. The long-chain alkyl silicone oil input pipe 15 and the vinyl silicone oil input pipe 16 are fixedly installed through the middle right side of the container 11 from top to bottom.

[0037] like Figure 4As shown, the cooling and mixing mechanism 2 includes a hollow drive screw 21, a U-shaped stirring tube 22, a drive motor 23, and drive gears 24. The hollow drive screw 21 penetrates the top of the inner cavity of the container 11 and extends to the top of the container 11, and is rotatably connected to the container 11 through bearings. Multiple U-shaped stirring tubes 22 are provided, and multiple 2b are evenly fixedly and permanently disposed on both sides of the bottom of the hollow drive screw 21, and are all connected to the hollow drive screw 21. Two drive gears 24 are provided, and the hollow drive screw 21 is connected to the drive motor 23 through the two drive gears 24.

[0038] By setting up the above-mentioned container 1 and cooling and mixing mechanism 2, the formula amount of long-chain alkyl silicone oil and vinyl silicone oil can be added into the container 11 through the long-chain alkyl silicone oil input pipe 15 and the vinyl silicone oil input pipe 16. The drive motor 23 is started. After the drive motor 23 is started, it drives the hollow drive screw 21 to rotate through the drive gear 24. When the hollow drive screw 21 rotates, the long-chain alkyl silicone oil and vinyl silicone oil are mixed through multiple U-shaped stirring tubes 22.

[0039] like Figure 3 and Figure 4 As shown, the cooling and vacuuming mechanism 3 includes a first exhaust pipe 31, a vacuum pump 32, and a second exhaust pipe 33. The first exhaust pipe 31 is fixedly disposed in the middle of the left side of the container 11. The output end of the first exhaust pipe 31 is fixedly connected to the input end of the vacuum pump 32. The input end of the second exhaust pipe 33 is fixedly connected to the output end of the vacuum pump 32. The output end of the second exhaust pipe 33 is connected to the top end of the hollow drive screw 21 through a rotary joint.

[0040] By setting up the above structure, the vacuum pump 32 can be started. After the vacuum pump 32 is started, the air inside the container 11 is drawn out through the first exhaust pipe 31. After the air inside the container 11 is drawn out, the outside air enters the container 11 through the feed hopper 14, and then continuously exchanges heat with the material through the top surface of the material. At the same time, the air drawn out by the vacuum pump 32 is input into the hollow drive screw 21 through the second exhaust pipe 33, and then enters the multiple U-shaped stirring tubes 22 along the hollow drive screw 21, and then exchanges heat with the material through the multiple U-shaped stirring tubes 22, thereby cooling the material from the inside.

[0041] like Figure 5As shown, the sealing and feeding mechanism 4 includes a lifting plate 41, an annular sealing plate 42, a storage hopper 43, and a discharge pipe 44. The lifting plate 41 is slidably nested inside the container 11 in the vertical direction. The lifting plate 41 is sleeved on the outside of the hollow drive screw 21 and is connected to the hollow drive screw 21 through a reciprocating thread. The annular sealing plate 42 is fixedly installed on the top of the lifting plate 41 and slides against the inner wall of the container 11. The storage hopper 43 is fixedly installed through the top of the lifting plate 41 and is located inside the clearance opening 12. The discharge pipe 44 is fixedly connected to the bottom of the storage hopper 43.

[0042] like Figure 5 As shown, the triggering mechanism 5 includes a fixed rod 51, a mounting plate 52, a longitudinal shaft 53, a first sealing block 54, and a second sealing block 55. The fixed rod 51 is fixedly installed on the top right side of the container 11. The mounting plate 52 is fixedly installed on the top of the fixed rod 51. The drive motor 23 and the vacuum pump 32 are both fixedly connected to the mounting plate 52. The longitudinal shaft 53 is fixedly installed at the bottom of the mounting plate 52, passes through the storage hopper 43 and the discharge pipe 44, and extends to the bottom of the discharge pipe 44. The first sealing block 54 and the second sealing block 55 are fixedly sleeved on the outside of the longitudinal shaft 53 from top to bottom. The first sealing block 54 seals the discharge pipe 44. The first sealing block 54 and the second sealing block 55 are both slidably installed on the inside of the discharge pipe 44 in the vertical direction.

[0043] By setting up the aforementioned sealing and feeding mechanism 4 and triggering mechanism 5, the drive motor 23 and vacuum pump 32 can be installed and fixed using the mounting plate 52. At the same time, during the rotation of the hollow drive screw 21, the hollow drive screw 21 drives the lifting plate 41 to continuously descend. When the lifting plate 41 descends, it drives the annular sealing plate 42 and the storage hopper 43 to descend synchronously. During the descent of the storage hopper 43, the longitudinal shaft 53 drives the first sealing block 54 to rise relative to each other inside the feed pipe 44. When the descent distance of the lifting plate 41 reaches the first threshold, the material is cooled down. At the same time, the lifting plate 41 seals the feed hopper 14 through the annular sealing plate 42. At this time, outside air cannot enter the interior of the container 11 through the feed hopper 14. The air inside the container 11 is gradually extracted, and the interior of the container 11 is in a negative pressure state.

[0044] Subsequently, when the first sealing block 54 is released from the blockage of the feed pipe 44 by the longitudinal shaft 53, the platinum catalyst inside the storage hopper 43 quickly passes through the annular channel between the inner wall of the first sealing block 54 and the longitudinal shaft 53 and falls into the container 11 under the influence of the negative pressure inside the container 11 and its own gravity, thus completing the addition of the platinum catalyst. Example

[0045] The preparation method specifically includes the following steps:

[0046] S1. Add the formulated amount of long-chain alkyl silicone oil and vinyl silicone oil into the container 11 through the long-chain alkyl silicone oil inlet pipe 15 and the vinyl silicone oil inlet pipe 16. Start the drive motor 23. After the drive motor 23 starts, it drives the hollow drive screw 21 to rotate through the drive gear 24. When the hollow drive screw 21 rotates, it mixes the long-chain alkyl silicone oil and vinyl silicone oil through multiple U-shaped stirring pipes 22. During the mixing process, the platinum catalyst is added to the inside of the storage hopper 43 through the top opening of the storage hopper 43.

[0047] S2. After mixing, the formula amount of alumina filler is added through the feed hopper 14. At this time, while the U-shaped stirring tube 22 is mixing the material, the electric heating element inside the container 11 is activated to heat and mix the material.

[0048] S3. Start vacuum pump 32. After vacuum pump 32 starts, it draws air from inside container 11 through first exhaust pipe 31. After the air inside container 11 is drawn out, outside air enters inside container 11 through feed hopper 14 and continuously exchanges heat with the material through the top surface of the material. At the same time, the vacuum pump 32 inputs the drawn air into the hollow drive screw 21 through second exhaust pipe 33, and then enters the multiple U-shaped stirring tubes 22 along the hollow drive screw 21. The air then exchanges heat with the material through the multiple U-shaped stirring tubes 22, and the material is cooled from the inside.

[0049] S4. During the rotation of the hollow drive screw 21, the hollow drive screw 21 drives the lifting plate 41 to continuously descend. When the lifting plate 41 descends, it drives the annular sealing plate 42 and the storage hopper 43 to descend synchronously. During the descent of the storage hopper 43, the longitudinal shaft 53 drives the first sealing block 54 to rise relative to the inside of the feed pipe 44. When the descent distance of the lifting plate 41 reaches the first threshold, the material is cooled down. At the same time, the lifting plate 41 seals the feed hopper 14 through the annular sealing plate 42. At this time, the outside air cannot enter the interior of the container 11 through the feed hopper 14. The air inside the container 11 is gradually extracted, and the interior of the container 11 is in a negative pressure state.

[0050] S5. When the lifting plate 41 descends to the second threshold, the first sealing block 54 is released from the blockage of the feed pipe 44 under the action of the longitudinal shaft 53. At this time, the platinum catalyst inside the storage hopper 43 quickly passes through the annular channel between the inner wall of the first sealing block 54 and the longitudinal shaft 53 and falls into the container 11 under the influence of the negative pressure inside the container 11 and its own gravity, thereby completing the addition of the platinum catalyst.

[0051] S6. When the lifting plate 41 descends to the third threshold, the platinum catalyst addition is completed. At the same time, the second sealing block 55 enters the inside of the feed pipe 44 under the drive of the longitudinal shaft 53, and then seals the feed pipe 44 again. At this time, as the vacuum pump 32 continues to work, the inside of the container 11 is gradually evacuated. At this time, multiple U-shaped stirring tubes 22 mix the materials under vacuum.

[0052] S7. When the lifting plate 41 descends to the fourth threshold, the lifting plate 41 moves to the lowest end of the reciprocating thread on the outside of the hollow drive screw 21. Subsequently, as the hollow drive screw 21 continues to rotate, the lifting plate 41 begins to rise and reset along the hollow drive screw 21. After the lifting plate 41 is completely reset, the mixing is completed, and mixture A is obtained. Mixture A is fed into a container containing mixture B through the discharge pipe 13 for mixing, and a low-viscosity, high-thermal-conductivity potting compound is obtained.

[0053] It should also be noted that mixture B is prepared by mixing long-chain alkyl silicone oil, vinyl silicone oil and hydrogen-containing silicone oil at room temperature, adding alumina filler at the prescribed amount, heating and stirring, then letting it stand and cool down before adding tackifier and inhibitor and stirring under vacuum.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

At this time, the platinum catalyst inside the storage hopper (43) quickly passes through the annular channel between the inner wall of the first sealing block (54) and the longitudinal shaft (53) and falls into the inside of the container (11) under the influence of the negative pressure inside the container (11) and its own gravity, thereby completing the addition of the platinum catalyst. S6. When the lifting plate (41) descends to the third threshold, the platinum catalyst is added. At the same time, the second sealing block (55) enters the inside of the feed pipe (44) under the drive of the longitudinal shaft (53), and then seals the feed pipe (44) again. At this time, as the vacuum pump (32) continues to work, the inside of the container (11) is gradually evacuated. At this time, multiple U-shaped stirring tubes (22) mix the materials under vacuum. S7. When the lifting plate (41) descends to the fourth threshold, the lifting plate (41) moves to the lowest end of the reciprocating thread on the outside of the hollow drive screw (21). Subsequently, as the hollow drive screw (21) continues to rotate, the lifting plate (41) begins to rise and reset along the hollow drive screw (21). After the lifting plate (41) is completely reset, the mixing is completed and mixture A is obtained. Mixture A is fed into a container containing mixture B through the discharge pipe (13) for mixing to obtain a low-viscosity, high-thermal-conductivity potting compound.
