Abstract
Description
A high-temperature resistant electronic component and its manufacturing process Technical Field
[0001] This invention relates to the technical field of high-temperature resistant electronic components, and in particular to a high-temperature resistant electronic component and its manufacturing process. Background Technology
[0002] Electronic components are the basic units that make up electronic devices and systems. They include various types such as resistors, capacitors, inductors, and electronic transformers. They are usually composed of several parts and have versatility. Among them, the power electronic transformer is the core component for realizing the conversion and transmission of electrical energy. The performance of its internal components directly determines the efficiency and reliability of the entire system.
[0003] During the manufacturing process, power electronic transformers need to be packaged to meet comprehensive requirements such as insulation, heat dissipation, mechanical strength, and cost control. The packaging types are mainly divided into two categories: plastic packaging and non-plastic packaging. In plastic packaging, injection molding is a key process that can provide effective protection and mechanical support for the internal chips. In this process, vacuum injection molding equipment is usually used to seal the pins and other parts of the power electronic transformer to minimize the generation of air bubbles during the packaging process, thereby ensuring the packaging quality and service life of the device.
[0004] In existing technologies, such as Chinese patent CN210822950U, a vacuum filling device for encapsulating adhesives is disclosed. This device adopts a three-layer filling structure including a feeding cavity layer, a rotating blade mechanism layer, and a feeding layer, and works with a vacuum pump to create a negative pressure environment to achieve the filling operation of high-viscosity adhesives. Although this design can alleviate the problems of material blockage and vacuum failure to a certain extent, in practical applications, such filling equipment and conventional injection molding equipment still have the following limitations: when the injection molding material has a large internal volume, air bubbles mixed in with the molten material are difficult to be fully and thoroughly extracted, which may result in residual air bubbles inside the encapsulated power electronic transformer, thereby affecting the product yield and long-term reliability.
[0005] Therefore, a high-temperature resistant electronic component and its manufacturing process are proposed to solve the above problems. Summary of the Invention
[0006] To address the problems mentioned in the background art, the present invention provides a high-temperature resistant electronic component and its manufacturing process.

[0008] Optionally, the main body of the frame is made of high-temperature resistant plastic material;
[0009] Specifically, the high-temperature resistant plastic material is polyphenylene sulfide.
[0010] A manufacturing process for a high-temperature resistant electronic component includes the following steps:

[0016] The filling and injection molding equipment in step S4 includes an equipment housing and an injection barrel. The injection barrel is installed through the upper surface of the equipment housing. A discharge barrel is provided on the upper side of the injection barrel and is fixed to the equipment housing. A material distribution mechanism is provided between the injection barrel and the discharge barrel. The material distribution mechanism has multiple rotatable cavities inside. The upper and lower ends of the material distribution mechanism are fixed to the injection barrel and the discharge barrel, respectively. The material distribution mechanism is connected to the injection barrel and the discharge barrel. The injection barrel and the discharge barrel are connected to two adjacent cavities, respectively. The discharge barrel is equipped with a power mechanism to control the rotation of the cavities inside the material distribution mechanism.
[0017] Optionally, a vacuum end cap is installed on the upper surface of the dispersing material transfer mechanism. The vacuum end cap can evacuate the cavity inside that is not connected to the injection barrel and the discharge barrel. Vacuum tubes are installed on the surfaces of both the injection barrel and the discharge barrel.
[0018] Optionally, the material dispersing mechanism includes a fixed support ring and a movable ring. The movable ring is rotatably sleeved on the outer surface of the fixed support ring. The fixed support ring is coaxially arranged with the injection barrel and the discharge barrel. Multiple cavities are opened through the upper surface of the movable ring.

The upper end of the injection barrel is inserted and installed on the bottom surface of the fixed support ring. The vacuum end cap is installed through the upper surface of the fixed support ring. The power mechanism controls the movable ring to rotate relative to the fixed support ring.
[0019] Optionally, the power mechanism includes a power shaft, a transmission shaft, and a force transmission gear ring. The force transmission gear ring is rotatably mounted on the upper surface of the fixed support ring. A drive gear is mounted on the lower end of the transmission shaft. The drive gear meshes with the force transmission gear ring. Multiple cavity-changing arc-shaped toothed plates are coaxially mounted on the upper surface of the force transmission gear ring. A driven gear ring is coaxially mounted on the outer ring surface of the movable ring. A double tooth body meshes with the circumferential surface of the driven gear ring. The gear portion on the upper side of the double tooth body is tangential to the outer ring surface of the cavity-changing arc-shaped toothed plate. The double tooth body is rotatably connected to the fixed support ring.
[0020] The drive shaft is rotatably connected to the outer ring surface of the discharge hopper, and the power shaft is coaxially installed at the axis of the injection molding hopper and the discharge hopper. The power shaft rotates relative to the injection molding hopper and the discharge hopper, and the power shaft and the drive shaft are driven by the first conveyor belt.
[0021] Optionally, a shell is installed through the upper surface of the fixed support ring on the upper side of the cavity communicating with the injection barrel. A pusher plate is slidably inserted inside the shell. The bottom surface of the pusher plate has beveled edges on all four sides. A threaded rod is installed on the upper surface of the pusher plate. The upper end of the threaded rod slides through the inner top wall of the shell. An internal threaded collar is threadedly sleeved at the outer end of the threaded rod. The internal threaded collar is rotatably connected to the upper surface of the shell. A vertical gear is provided on the side of the internal threaded collar away from the axis of the fixed support ring. The lower end of the vertical gear is rotatably inserted into the upper surface of the fixed support ring. The vertical gear and the internal threaded collar are driven by a second conveyor belt.
[0022] The shape and size of the pusher plate are adapted to the shape and size of the cavity.
[0023] Optionally, an outer arc-shaped toothed plate and an inner arc-shaped toothed plate are provided between each two adjacent arc-shaped toothed plates of the switching cavity. Both the outer arc-shaped toothed plate and the inner arc-shaped toothed plate are fixed with the force transmission toothed ring. The outer arc-shaped toothed plate is located on the outer ring side of the inner arc-shaped toothed plate. The outer arc-shaped toothed plate and the inner arc-shaped toothed plate mesh with the outer and inner sides of the vertical gear respectively as they move with the force transmission toothed ring.
[0024] Optionally, both the outer arc-shaped toothed plate and the inner arc-shaped toothed plate are coaxially arranged with the fixed support ring, and the outer arc-shaped toothed plate, the inner arc-shaped toothed plate and the cavity-changing arc-shaped toothed plate are staggered.
[0025] Optionally, the power shaft is equipped with a stirring plate at one end inside both the discharge barrel and the injection barrel. The stirring plates are spirally distributed and have through grooves on their surfaces.
[0026] In summary, the present invention has the following beneficial technical effects:
[0027] This invention, through the coordination of components such as a movable ring, cavities, and a vacuum end cap, allows the molten material in the discharge bucket to disperse and flow into different cavities as the movable ring rotates. The vacuum end cap then applies a vacuum to the molten material inside the corresponding connected cavities, making it easier to extract air bubbles from the dispersed molten material and reducing the amount of residual air bubbles inside the molten material.
[0028] This invention incorporates components such as a pusher plate, an inner arc-shaped toothed plate, an outer arc-shaped toothed plate, and a threaded rod. When the movable ring is not rotating, the inner and outer arc-shaped toothed plates sequentially mesh with the vertical gear. The vertical gear drives the threaded collar to rotate in both directions via transmission, pushing the pusher plate downwards and then back upwards. As the pusher plate moves downwards, it pushes the molten material inside the vacuum-evacuated cavity into the injection molding barrel, preventing the molten material remaining in the cavity after vacuuming from affecting the storage of new molten material next time.
[0029] This invention uses agitator plates, which rotate in the power shaft, causing the corresponding agitator plates inside the discharge tank and injection tank to rotate. Since the agitator plates are spirally distributed, they push the material to move up and down, making the molten material move continuously and facilitating the extraction of internal air bubbles.
[0030] This invention uses high-temperature resistant plastic as the main frame material. Polyphenylene sulfide has excellent heat resistance, dimensional stability and injection molding properties, making it particularly suitable as a packaging frame for electronic components. This enables the prepared electronic circuit transformer to have high-temperature resistance. This structure can not only maintain stable mechanical strength and insulation performance in high-temperature environments, but also effectively prevent material aging or electrical performance degradation caused by temperature rise, thereby improving the reliability and service life of components under high-temperature conditions.

[0041] The present invention will be further described in detail below with reference to Figures 1-9.
[0042] This invention discloses a high-temperature resistant electronic component and its manufacturing process. As shown in Figures 1-9, a high-temperature resistant electronic component includes a frame body 1, with an encapsulated electromagnetic coil 2 installed at the center of the frame body 1. The frame body 1 is made of high-temperature resistant plastic material to ensure the high-temperature resistance of the internal electronic components.
[0043] A manufacturing process for a high-temperature resistant electronic component includes the following steps:
[0044] S1. Select the appropriate coil body and outer frame with pins;
[0045] S2. Seal the middle part of the coil body inside the outer frame to provide mechanical support, heat dissipation and electrical connection;
[0046] S3. Connect the coil motor to the inner lead wire of the outer frame with a thin metal wire (gold wire, aluminum wire or copper wire) to achieve electrical conduction;
[0047] S4. Use a filling and injection molding equipment to heat and pressurize the high-temperature resistant plastic into the mold, wrap the middle part of the coil body, and then let it stand to solidify, forming a hard outer shell on the middle part of the coil body;
[0048] S5, remove burrs, post-curing and electroplating, and finally use a rib cutting and forming machine to cut off the redundant parts of the outer frame.
[0049] The filling and injection molding equipment in step S4 includes an equipment housing 3 and an injection barrel 4. The equipment housing 3 has a transparent observation window and two windows that can be opened and closed on the outside. The injection barrel 4 is installed through the upper surface of the equipment housing 3. A discharge tank 5 is provided on the upper side of the injection barrel 4. The discharge tank 5 is fixed to the equipment housing 3. Heating components are installed inside both the discharge tank 5 and the injection barrel 4 to ensure that the internal molten material does not solidify at the required temperature.
[0050] A material dispersing mechanism 6 is provided between the injection barrel 4 and the discharge barrel 5. The material dispersing mechanism 6 has multiple rotatable cavities 7 inside. The upper and lower ends of the material dispersing mechanism 6 are fixed to the injection barrel 4 and the discharge barrel 5, respectively. The material dispersing mechanism 6 is connected to the injection barrel 4 and the discharge barrel 5. The injection barrel 4 and the discharge barrel 5 are connected to two adjacent cavities 7, respectively. The molten material in the discharge barrel 5 can be dispersed and filled into the cavity 7. The discharge barrel 5 is equipped with a power mechanism 8 that controls the rotation of the cavity 7 inside the material dispersing mechanism 6.
[0051] The upper surface of the material distribution mechanism 6 is equipped with a vacuum end cap 9. The vacuum end cap 9 can evacuate the cavity 7 that is not connected to the injection barrel 4 and the discharge barrel 5. Vacuum tubes 10 are installed on the surfaces of the injection barrel 4 and the discharge barrel 5. The vacuum end cap 9 and the two vacuum tubes 10 are connected to the vacuum equipment. The vacuum equipment evacuates the molten material inside the injection barrel 4, the discharge barrel 5 and the cavity 7 through the two vacuum tubes 10 and the vacuum end cap 9 respectively.
[0052] The material transfer mechanism 6 includes a fixed support ring 61 and a movable ring 62. The movable ring 62 is rotatably sleeved on the outer surface of the fixed support ring 61. The outer ring surface of the fixed support ring 61 is set in an annular recess. The movable ring 62 is located in the annular recess of the fixed support ring 61. The upper and lower sides of the fixed support ring 61 respectively seal the upper and lower ends of the cavity 7. The fixed support ring 61 and the upper and lower ends of the movable ring 62 are in sealed contact to ensure that no gas leakage occurs during the rotation of the movable ring 62. The fixed support ring 61 is coaxially arranged with the injection barrel 4 and the discharge barrel 5. Multiple cavities 7 are opened through the upper surface of the movable ring 62. The multiple cavities 7 are evenly distributed in a circular array around the axis of the movable ring 62. The lower end of the discharge barrel 5 is inserted and installed on the upper surface of the fixed support ring 61. The upper end of the injection barrel 4 is inserted and installed on the bottom surface of the fixed support ring 61. The vacuum end cap 9 is installed through the upper surface of the fixed support ring 61. The power mechanism 8 controls the movable ring 62 to rotate relative to the fixed support ring 61.
[0053] The power mechanism 8 includes a power shaft 81, a transmission shaft 82, and a force transmission gear ring 83. The force transmission gear ring 83 is rotatably mounted on the upper surface of the fixed support ring 61. A drive gear 88 is mounted on the lower end of the transmission shaft 82, and the drive gear 88 meshes with the force transmission gear ring 83. Multiple cavity-changing arc-shaped gear plates 84 are coaxially mounted on the upper surface of the force transmission gear ring 83. A driven gear ring 85 is coaxially mounted on the outer ring surface of the movable ring 62. A double tooth body 86 meshes with the circumferential surface of the driven gear ring 85. The double tooth body 86 consists of two coaxially arranged gear bodies. The upper gear portion of the double tooth body 86 is tangential to the outer ring surface of the cavity-changing arc-shaped gear plate 84. The double tooth body 86 is rotatably connected to the fixed support ring 61. As the cavity-changing arc-shaped gear plate 84 rotates with the force transmission gear ring 83, the cavity-changing arc-shaped gear plate 84 intermittently meshes with the double tooth body 84. 6. In the engagement of a cavity-changing arc-shaped toothed plate 84 and a double toothed body 86, the double toothed body 86 drives the movable ring 62 to rotate by engaging with the driven toothed ring 85. As the cavity-changing arc-shaped toothed plate 84 and the double toothed body 86 disengage, the cavity 7 on the surface of the movable ring 62 rotates at the angle between two adjacent cavities 7, causing the adjacent cavities 7 of the discharge tank 5 and the injection tank 4 to rotate and connect with the discharge tank 5 and the injection tank 4 respectively. As the movable ring 62 rotates, the molten material in the discharge tank 5 is sequentially filled into different cavities 7. Then, the cavity 7 filled with molten material is connected to the vacuum end cap 9 and is vacuumed. The vacuumed cavity 7, as it rotates with the movable ring 62, connects to the injection tank 4, causing the vacuumed molten material to fall into the injection tank 4.
[0054] An injection head is installed at the lower end of the injection barrel 4. A spiral plate is installed at the lower end of the power shaft 81 to apply downward force to the molten material. At the same time, a structure for conveying the molten material is installed inside the injection head.
[0055] The power shaft 81 is located inside the discharge tank 5 and the injection tank 4, and a stirring plate 19 is installed at one end. The stirring plate 19 is spirally distributed and has through grooves on its surface. When the power shaft 81 rotates, it drives the stirring plate 19 inside the discharge tank 5 and the injection tank 4 to rotate. The spirally distributed stirring plate 19 stirs the molten material during rotation, which helps to vacuum the air bubbles inside the molten material.
[0056] The drive shaft 82 is rotatably connected to the outer ring surface of the discharge hopper 5. The power shaft 81 is coaxially installed at the axis of the injection molding hopper 4 and the discharge hopper 5. A motor that drives the power shaft 81 to rotate is installed at the upper end of the discharge hopper 5. The power shaft 81 rotates relative to the injection molding hopper 4 and the discharge hopper 5. The power shaft 81 and the drive shaft 82 are driven by the first conveyor belt 87.
[0057] A housing 11 is installed through the upper surface of the fixed support ring 61 on the upper side of the cavity 7 connected to the injection molding barrel 4. A pusher plate 12 is slidably inserted inside the housing 11. The bottom surface of the pusher plate 12 has beveled edges on all four sides. Each time the movable ring 62 rotates, the adjacent cavities 7 rotate to the lower side of the pusher plate 12. The shape and size of the pusher plate 12 are adapted to the shape and size of the cavity 7. A threaded rod 13 is installed on the upper surface of the pusher plate 12. The upper end of the threaded rod 13 slides through the inner top wall of the housing 11, and one end of the threaded rod 13 is located outside the housing 11. The threaded sleeve is fitted with an internal threaded collar 14. During forward and reverse rotation, the internal threaded collar 14 meshes with the threaded rod 13, thereby driving the pusher plate 12 to move up and down. The internal threaded collar 14 is rotatably connected to the upper surface of the housing 11. A vertical gear 15 is provided on the side of the internal threaded collar 14 away from the axis of the fixed support ring 61. The lower end of the vertical gear 15 is rotatably inserted into the upper surface of the fixed support ring 61. The vertical gear 15 and the internal threaded collar 14 are driven by the second conveyor belt 16. During the rotation of the vertical gear 15, the internal threaded collar 14 is driven to rotate synchronously through the second conveyor belt 16.
[0058] Between each pair of adjacent cavity-changing arc-shaped toothed plates 84, there is an outer arc-shaped toothed plate 17 and an inner arc-shaped toothed plate 18. Both the outer arc-shaped toothed plate 17 and the inner arc-shaped toothed plate 18 are fixed with the force transmission toothed ring 83. The outer arc-shaped toothed plate 17 is located on the outer ring side of the inner arc-shaped toothed plate 18. As the outer arc-shaped toothed plate 17 and the inner arc-shaped toothed plate 18 move with the force transmission toothed ring 83, they respectively mesh with the outer and inner sides of the vertical gear 15. Both the outer arc-shaped toothed plate 17 and the inner arc-shaped toothed plate 18 are coaxially arranged with the fixed support ring 61. The outer arc-shaped toothed plate 17, the inner arc-shaped toothed plate 18 and the cavity-changing arc-shaped toothed plate 84 are staggered. As the force transmission toothed ring 83 rotates, it drives the outer arc-shaped toothed plate 17 and the inner arc-shaped toothed plate 18 to mesh with the vertical gear 15 in sequence, which drives the pusher plate 12 to move up and down reciprocally, and pushes the molten material in the lower cavity 7 into the injection barrel 4.
[0059] The working principle is as follows: After the molten material is placed into the discharge tank 5, it is sealed. The movable ring 62 drives multiple cavities 7 to connect with the discharge tank 5 and the injection tank 4 in sequence, dispersing and filling the multiple cavities 7. The molten material in the discharge tank 5 fills the connected cavities 7. The molten material in the cavity 7 connected to the injection tank 4 falls into the injection tank 4. The molten material in the discharge tank 5 falls into the cavity 7 and rotates with the movable ring 62. The vacuum end cap 9 evacuates the molten material inside the lower cavity 7 to reduce the residual air bubbles inside the molten material during vacuuming.
[0060] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
