Description
Technical Field
[0001] The present invention relates to the technical field of electronic components, and particularly relates to a method for potting an inductor and a potting fixture. Background Art
[0002] An inductor is an electromagnetic induction component, which is formed by winding an insulated wire around a winding support or an iron core for a certain number of turns. This coil is called an inductance coil or an inductor. During the processing of an inductor, it is necessary to pot the inductor semi-finished product to improve the performance, reliability and service life of the inductor.
[0003] During the potting process of the inductor semi-finished product, it is necessary to install the product into the fixture. To ensure that the bottom and the outside of the inductor are completely covered with glue, the inductor semi-finished product should be in a suspended state inside the fixture during potting. The existing solution is to set protrusions on the inner side of the fixture to support the inductor semi-finished product, but this method requires sacrificing part of the outer dimension of the inductor. In a compact electronic device, sacrificing the outer dimension of the inductor will affect the installation of the inductor and its compatibility with other circuit components.
[0004] Therefore, the present invention provides a method for potting an inductor and a potting fixture. Summary of the Invention
[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.
[0006] The present invention provides a method for potting an inductor, including the following steps:
[0007] S1. Assemble the fixture: Assemble and combine two symmetrical fixtures into a state to be potted.
[0008] S2. Install the inductor semi-finished product: Use a fixing mechanism to adhere to the top of the inductor semi-finished product, and support the inductor semi-finished product on the top of the fixture through the fixing mechanism. The whole inductor semi-finished product is in a suspended state in the forming groove of the fixture.
[0009] S3. Potting: Pot at the center of the inductor semi-finished product, and wait for the glue to dry and solidify to form an inductor finished product.
[0010] S4. Disassemble the inductor finished product: Separate the fixing mechanism and the fixture from the inductor finished product one by one.
[0011] By adopting the above technical solution, the inductor semi-finished product is in a suspended state before potting, so that the potting covers the entire bottom and the outside of the inductor semi-finished product, and there is no notch on the outside of the inductor finished product formed after the glue dries.
[0012] On the other hand, the present application also provides an inductor potting fixture, which includes a mold mechanism. A backing plate assembly is placed on the top of the mold mechanism. The fixing mechanism includes a fixing component, and the fixing component is installed on both sides of the top of the mold mechanism. When the mold mechanism is in a state to be potted, it drives the fixing component to fix the semi-finished inductor. During this process, the backing plate assembly is used to position the semi-finished inductor. After the fixing is completed, the backing plate assembly is taken away, and the height of the top of the fixing component drops, and the semi-finished inductor is suspended and installed inside the mold mechanism.
[0013] Preferably, the mold mechanism includes two potting mold components. A mounting seat assembly is connected to the bottom between the two potting mold components. A first electric push rod is installed between the potting mold component and the mounting seat assembly.
[0014] By adopting the above technical solution, when the potting mold components are separated, it is easier to take out the finished inductor.
[0015] Preferably, the potting mold component includes a mold body. A potting groove is opened at the top of the side of the mold body close to the mounting seat assembly. An activity groove is opened at the bottom of the side of the mold body close to the mounting seat assembly. The output shaft of the first electric push rod is fixedly connected to the side wall of the activity groove.
[0016] Preferably, the mounting seat assembly includes a mounting seat body. Second mounting grooves are opened in the middle of the front, back, left and right sides of the mounting seat body. The first electric push rod is installed inside the second mounting groove.
[0017] By adopting the above technical solution, the two mold bodies are always symmetric about the front center line of the mounting seat body.
[0018] Preferably, the backing plate assembly includes a backing plate body. A limiting ring is fixedly connected to the top of the backing plate body. The center of the limiting ring is located on the center line of the front of the backing plate body. A clamping block is fixedly connected to the center of the bottom of the backing plate body. A first limiting groove with a clearance fit with the thickness of the clamping block is opened at the center of the top of the mounting seat body. A stop block is fixedly connected to the back of the first limiting groove. The width of the first limiting groove is the same as the width of the clamping block.
[0019] By adopting the above technical solution, the accuracy of positioning the semi-finished inductor by the backing plate assembly is ensured.
[0020] Preferably, first mounting grooves are formed on both sides of the top of the mold body. The fixing component includes two second electric push rods. The bottoms of the second electric push rods are installed inside the first mounting grooves. Fixing blocks are fixedly connected to the tops of the two second electric push rods. Moving block assemblies are connected to one adjacent side of the two fixing blocks. Moving rod assemblies are connected to one adjacent side of the two moving block assemblies. An adhesive component is arranged between the two moving rod assemblies.
[0021] Preferably, the adhesive component includes an adhesive seat. A placement groove is formed in the center of the top of the adhesive seat. A glue leakage hole is formed in the center of the bottom of the adhesive seat. Activity square grooves are formed in the middle of both sides of the adhesive seat. Second limiting grooves are formed at the top and bottom of the activity square groove.
[0022] Preferably, the moving rod assembly includes a rod body. Third limiting grooves are formed at the top and bottom of the middle of the rod body. Limiting square blocks are fixedly connected to the top and bottom of one side of the rod body close to the adhesive seat. A puncture needle is fixedly connected to one end of the rod body close to the adhesive seat. An annular square groove is formed in the bottom of the adhesive seat. A heating ring is fixedly installed inside the annular square groove of the adhesive seat.
[0023] By adopting the above technical solution, after the glue injection is completed, the heating ring is started to melt the fixed glue, which is more convenient for separating the inductor finished product from the adhesive seat, and at this time, the glue remaining at the bottom of the adhesive seat is easier to remove.
[0024] Preferably, the moving block assembly includes a moving block body. A moving groove is formed on one side of the moving block body close to the moving rod assembly. Limiting blocks are fixedly connected to the top wall and the bottom wall of one side of the moving groove close to the moving rod assembly. The width of the limiting block is in clearance fit with the width of the third limiting groove.
[0025] By adopting the above technical solution, when the two mold bodies are combined and connected, the puncture needles are sufficient to pierce both sides of the glue mass, but the two puncture needles will not collide with each other, prolonging the service life of the puncture needles.
[0026] This application includes at least one of the following beneficial technical effects: For an inductor potting method and a potting fixture according to the present invention, by providing a mold mechanism and a fixing component that cooperate with each other, when the mold mechanism moves to the state to be potted, the fixing component moves accordingly and punctures a liquid glue mass with a plastic packaging on the outside. The liquid glue inside the glue mass flows from the glue leakage hole to the contact between the bottom of the glue sticking seat and the top of the inductor semi-finished product, quickly fixing the inductor semi-finished product. In this process, there is no need for manual application of liquid glue, avoiding the liquid glue from sticking to the operator's hands. Moreover, the second electric push rod drives the glue sticking seat to move downward, suspending the inductor semi-finished product at the top of the forming groove of the fixture, so that the inductor semi-finished product is in a suspended state before potting, enabling the potting to cover the entire bottom and outside of the inductor semi-finished product. After the colloid dries, there are no gaps on the outside of the formed inductor finished product, facilitating the subsequent installation of the inductor in an electronic device and its compatibility with other circuit components.
[0027] For an inductor potting method and a potting fixture according to the present invention, by providing a mold mechanism, when two potting mold components are combined and connected, it is the state to be potted of the mold mechanism. The first electric push rod drives the two potting mold components to approach or move away from each other. When the potting mold components are separated, it is easier to take out the inductor finished product.
[0028] For an inductor potting method and a potting fixture according to the present invention, by providing a backing plate component, before using the fixing component to install the inductor semi-finished product, the backing plate component needs to be placed on the top of the mold mechanism, and then the inductor semi-finished product is placed inside the limiting ring. When the backing plate component drives the inductor semi-finished product to descend after the fixing component fixes the inductor semi-finished product, the inductor semi-finished product can be suspended at the exact center of the forming groove of the fixture.

[0038] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described for some examples can also be combined in other examples. Embodiment
[0039] The technical solution of the present invention will be further elaborated in detail below in conjunction with the drawings of the specification and specific embodiments. An inductor glue-filling method provided by this application includes the following steps:
[0040] S1. Assemble the jig: Assemble and combine two symmetrical jigs into a state to be glue-filled.
[0041] S2. Install the semi-finished inductor: Use the fixing mechanism to install and connect to the top of the semi-finished inductor, and support the semi-finished inductor on the top of the jig through the fixing mechanism. The whole semi-finished inductor is in a suspended state in the forming groove of the jig.
[0042] S3. Glue-filling: Glue-fill at the center of the semi-finished inductor and wait for the glue to dry and solidify to form a finished inductor.
[0043] S4. Disassemble the finished inductor: Separate the fixing mechanism and the jig from the finished inductor one by one.
[0044] Specifically, by setting up a fixing mechanism to suspend the semi-finished inductor at the top of the forming groove of the jig, the semi-finished inductor is in a suspended state before potting, so that the potting covers the entire bottom and the outside of the semi-finished inductor. After the colloid dries, there is no notch on the outside of the finished inductor, which is convenient for the subsequent installation of the inductor in the electronic device and the compatibility with other circuit components.
[0045] On the other hand, please refer to Figures 1 to 7 , the embodiment of the present application also provides an inductor potting jig. Please pay special attention to refer to Figure 1 and Figure 2 , which includes a mold mechanism 1. A backing plate assembly 2 is placed on the top of the mold mechanism 1. The fixing mechanism includes a fixing component 3. The fixing component 3 is installed on both sides of the top of the mold mechanism 1. When the mold mechanism 1 is in the state of waiting for potting, it drives the fixing component 3 to fix the semi-finished inductor. During this process, the backing plate assembly 2 is used to position the semi-finished inductor. After the fixing is completed, the backing plate assembly 2 is taken away, and the top height of the fixing component 3 drops, and the semi-finished inductor is suspended and installed inside the mold mechanism 1.
[0046] Please pay special attention to refer to Figure 2 , Figure 3 , the mold mechanism 1 includes two potting mold components 101. There is a mounting seat assembly 102 connected to the bottom between the two potting mold components 101. A first electric push rod 103 is installed between the potting mold component 101 and the mounting seat assembly 102.
[0047] Specifically, when the two potting mold components 101 are combined and connected, it is the state of the mold mechanism 1 waiting for potting. The first electric push rod 103 drives the two potting mold components 101 to approach or move away from each other. When the potting mold components 101 are separated, it is easier to take out the finished inductor.
[0048] Please pay special attention to refer to Figure 3 , the potting mold component 101 includes a mold body 1011. A potting groove 1013 is opened at the top of the side of the mold body 1011 close to the mounting seat assembly 102. An activity groove 1014 is opened at the bottom of the side of the mold body 1011 close to the mounting seat assembly 102. The output shaft of the first electric push rod 103 is fixedly connected to the side wall of the activity groove 1014.
[0049] Please pay special attention to refer to Figure 3 , the mounting seat assembly 102 includes a mounting seat body 1021. Second mounting grooves 1022 are opened in the middle of the front, back, left, and right sides of the mounting seat body 1021. The first electric push rod 103 is installed inside the second mounting groove 1022.
[0050] Specifically, the initial state is as shown in Figure 1 , Figure 2As shown, at this time, the output shaft of the first electric push rod 103 extends to the longest state. When glue injection is required, start the output shaft of the first electric push rod 103 to pull the two mold bodies 1011 closer to each other at equal distances until the mold bodies 1011 are combined and joined. At this time, the two glue injection grooves 1013 are joined to form a fixture forming groove. Both ends of the mounting seat main body 1021 are respectively immersed in the inner side of the movable groove 1014 and covered by the movable groove 1014. The two mold bodies 1011 are always symmetric about the front midline of the mounting seat main body 1021.
[0051] Please refer specifically to Figure 2 、 Figure 4 , the spacer assembly 2 includes a spacer main body 201. A limit ring 202 is fixedly connected to the top of the spacer main body 201. The center of the limit ring 202 is located on the front midline of the spacer main body 201. A clamping block 203 is fixedly connected to the center of the bottom of the spacer main body 201. A first limit groove 1023 with a clearance fit with the thickness of the clamping block 203 is opened at the center of the top of the mounting seat main body 1021. A stop block 1024 is fixedly connected to the back of the first limit groove 1023. The width of the first limit groove 1023 is the same as the width of the clamping block 203.
[0052] Specifically, before installing the inductor semi-finished product using the fixing component 3, the spacer assembly 2 needs to be placed on the top of the mold mechanism 1, and then the inductor semi-finished product is placed inside the limit ring 202; in order to ensure the accuracy of the positioning of the inductor semi-finished product by the spacer assembly 2, the clamping block 203 and the first limit groove 1023 are arranged to cooperate with each other, so that the midpoint of the front of the spacer main body 201 is aligned with the midpoint of the front of the mounting seat main body 1021, and the center of the limit ring 202 and the position of the center of the circle when the two glue injection grooves 1013 are joined are on the same vertical line. The inner shape of the limit ring 202 has a clearance fit with the outer shape of the inductor, and the number of limit rings 202 is the same as the number of glue injection grooves 1013 opened at the top of a single mold body 1011; the operator pushes the spacer main body 201 along the inner side of the first limit groove 1023 towards the stop block 1024 through the clamping block 203. The stop block 1024 blocks the clamping block 203. Just when the bottom of the clamping block 203 is completely inside the first limit groove 1023, the back of the clamping block 203 contacts the front of the stop block 1024.
[0053] Please refer specifically to Figure 1 、 Figure 3 、 Figure 6, on both sides of the top of the mold body 1011, first mounting grooves 1012 are provided. The fixing component 3 includes two second electric push rods 305. The bottom of the second electric push rod 305 is mounted inside the first mounting groove 1012. On the top of both second electric push rods 305, fixing blocks 304 are fixedly connected. On one adjacent side of the two fixing blocks 304, moving block assemblies 303 are connected. On one adjacent side of the two moving block assemblies 303, moving rod assemblies 302 are connected. Between the two moving rod assemblies 302, an adhesive component 301 is provided.
[0054] Specifically, the second electric push rod 305 is mounted inside the first mounting groove 1012. When the first electric push rod 103 drives the two mold bodies 1011 to approach each other, the second electric push rod 305 moves together with the mold body 1011, thereby driving the fixing block 304 to push the two moving block assemblies 303 to approach each other. The moving block assembly 303 drives the moving rod assemblies 302 to approach each other, so that the length of the whole top of the fixing component 3 is synchronously shortened during the process of the two mold bodies 1011 approaching each other.
[0055] Please refer specifically to Figure 7 , the adhesive component 301 includes an adhesive seat 3011. In the center of the top of the adhesive seat 3011, a storage groove 3012 is provided. In the center of the bottom of the adhesive seat 3011, a glue leakage hole 3013 is provided. In the middle of both sides of the adhesive seat 3011, movable square grooves 3014 are provided. At the top and bottom of the movable square groove 3014, second limiting grooves 3015 are provided.
[0056] Specifically, a liquid glue mass with a plastic packaging on the outside is placed in the storage groove 3012. The top surface size of the glue leakage hole 3013 is smaller than the top surface size of the storage groove 3012, so that the liquid glue mass with a plastic packaging on the outside can be stuck inside the storage groove 3012. When the moving rod assembly 302 moves, it moves along the movable square groove 3014 and the second limiting groove 3015.
[0057] Please refer specifically to Figure 7 , the moving rod assembly 302 includes a rod body 3021. At the top and bottom of the middle of the rod body 3021, third limiting grooves 3022 are provided. At the top and bottom of one side of the rod body 3021 close to the adhesive seat 3011, limiting square blocks 3024 are fixedly connected. At one end of the rod body 3021 close to the adhesive seat 3011, a puncture needle 3023 is fixedly connected. At the bottom inside the adhesive seat 3011, an annular square groove is provided. Inside the annular square groove of the adhesive seat 3011, a heating ring 306 is fixedly installed.
[0058] Specifically, when the moving block assembly 303 drives the moving rod assembly 302 to approach each other, the rod body 3021 moves along the movable square groove 3014, and the limiting square block 3024 moves along the second limiting groove 3015 until the liquid glue mass with a plastic-sealed package on the outside placed inside the object placing groove 3012 is punctured by the puncture needle 3023. The liquid glue inside the glue mass flows from the glue leakage hole 3013 to the contact position between the bottom of the glue sticking seat 3011 and the top of the inductor semi-finished product. After waiting for the liquid glue to dry, the second electric push rod 305 is driven to raise the height of the glue sticking seat 3011, driving the inductor semi-finished product to be synchronously lifted to the top of the limiting ring 202. Then, the backing plate assembly 2 is withdrawn along the first limiting groove 1023 to take away the entire backing plate assembly 2. Then, the second electric push rod 305 is driven to make the output shaft of the second electric push rod 305 drive the height of the glue sticking seat 3011 to drop until the top of the inductor semi-finished product is flush with the top of the mold body 1011. At this time, the inductor semi-finished product is in a suspended state in the glue filling groove 1013, and there is no notch on the outer surface of the finally glue-filled inductor finished product; after the glue filling is completed, the heating ring 306 is started to melt the fixed glue, which is more convenient for separating the inductor finished product from the glue sticking seat 3011, and at this time, the glue remaining at the bottom of the glue sticking seat 3011 is easier to remove.
[0059] Please refer specifically to Figure 6 , the moving block assembly 303 includes a moving block main body 3031. A moving groove 3032 is formed on one side of the moving block main body 3031 close to the moving rod assembly 302. Limiting blocks 3033 are fixedly connected to both the top wall and the bottom wall on the side of the moving groove 3032 close to the moving rod assembly 302. The width of the limiting block 3033 is in clearance fit with the width of the third limiting groove 3022.
[0060] Specifically, as Figure 6 、 Figure 7As shown in the figure, this is the initial state of the fixing component 3. The limiting block 3033 is located on the side of the third limiting groove 3022 farthest from the adhesive component 301, and the limiting square block 3024 is located on the side of the second limiting groove 3015 closest to the moving block component 303. During the process of the moving block components 303 approaching each other: First, the moving block body 3031 moves toward the moving rod component 302, that is, the limiting block 3033 moves along the third limiting groove 3022. When it moves to the side of the third limiting groove 3022 closest to the adhesive component 301, the moving block component 303 will push the moving rod component 302 to move forward together. At this time, the limiting square block 3024 moves along the second limiting groove 3015, and the puncturing needle 3023 gradually approaches the glue mass until it punctures the glue mass. The moving block component 303 and the moving rod component 302 make the overall length of the top of the fixing component 3 decrease layer by layer, which can adapt to the distance change during the process of the mold bodies 1011 approaching each other, and will not directly drive the third limiting groove 3022 to be too close, so that when the two mold bodies 1011 are combined and joined, the puncturing needle 3023 is sufficient to puncture both sides of the glue mass, but the two puncturing needles 3023 will not collide with each other, extending the service life of the puncturing needle 3023.
[0061] Working principle: The initial state is as Figure 1 , Figure 2 shown. At this time, the output shaft of the first electric push rod 103 extends to the longest state. When glue filling is required, first place the backing plate component 2 on the top of the mold mechanism 1. The operator pushes the backing plate body 201 along the inner side of the first limiting groove 1023 toward the stop block 1024 through the block 203, and then places the inductor semi-finished product in the limiting ring 202 to ensure that the bottom of the inductor semi-finished product contacts the top of the backing plate body 201 inside the limiting ring 202 at this time, and the top of the inductor semi-finished product contacts the bottom of the adhesive seat 3011.
[0062] Then start the output shaft of the first electric push rod 103 to pull the two mold bodies 1011 to approach each other equally. The second electric push rod 305 is installed inside the first installation groove 1012. When the first electric push rod 103 drives the two mold bodies 1011 to approach each other, the second electric push rod 305 moves together with the mold bodies 1011, thereby driving the fixed block 304 to push the two moving block components 303 to approach each other. The moving block component 303 drives the moving rod component 302 to approach each other, so that the length of the overall top of the fixing component 3 is synchronously shortened during the process of the two mold bodies 1011 approaching each other, until the adjacent sides of the two mold bodies 1011 are respectively attached to both sides of the block 203. At this time, the liquid glue mass with a plastic packaging on the outside placed inside the placement groove 3012 has been punctured by the puncturing needle 3023, and the liquid glue inside the glue mass flows from the glue leakage hole 3013 to the contact position between the bottom of the adhesive seat 3011 and the top of the inductor semi-finished product, waiting for the liquid glue to dry.
[0063] After the liquid glue is completely dry, drive the second electric push rod 305 to raise the height of the glue sticking seat 3011 to drive the semi-finished inductor to be lifted synchronously to the top of the limit ring 202, and then draw out the backing plate assembly 2 along the first limit groove 1023 to take away the whole backing plate assembly 2. Then drive the second electric push rod 305 to make the output shaft of the second electric push rod 305 drive the height of the glue sticking seat 3011 to drop until the top of the semi-finished inductor is flush with the top of the mold body 1011. At this time, the semi-finished inductor is in a suspended state in the potting groove 1013. Potting is carried out from the center of the semi-finished inductor, and wait for the glue to dry and solidify to form a finished inductor;
[0064] After potting is completed, drive the second electric push rod 305 to raise the height of the glue sticking seat 3011 to drive the semi-finished inductor to be lifted synchronously. At the same time, drive the first electric push rod 103 to drive the two mold bodies 1011 to move away from each other, and take out the finished inductor from the mold body 1011. After taking out, start the heating ring 306 to melt the fixed glue, which is more convenient to separate the finished inductor from the glue sticking seat 3011, and at this time, the glue remaining at the bottom of the glue sticking seat 3011 is easier to remove.
[0065] The above describes the embodiments of the specific implementation manner, but this embodiment is not limited to the above specific implementation manner. The above specific implementation manner is only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
