Description

Technical Field

[0001] This application relates to the field of electronic component processing equipment technology, and in particular to an automated feeding mechanism for a hot press mold for inductors. Background Technology

[0002] Inductor thermoforming is an advanced inductor manufacturing process. In the production process, the blank material with the coil wound is usually placed in the mold first. Then, powder is filled into the gap between the coil and the inner wall of the mold. Under high temperature and high pressure, the powder and the coil are directly fused into a dense integral structure.

[0003] Currently, the mainstream technology in the industry uses T-Core inductor hot-press packaging machines, which mainly include the following steps: 1. Implantation and Detection The semi-finished product (T-Core) after winding is implanted into the intermediate mold, and 3D vision inspection is used to ensure accurate positioning; 2. Powder Filling and Testing An automated powder-filling mechanism fills the intermediate mold with magnetic powder, followed by 2D visual inspection to ensure uniform and defect-free powder filling. 3. Preheating and hot pressing After being filled with powder, the intermediate mold is preheated and then sent to a hot press, where it is pressed and shaped under high temperature and pressure to form an insulating layer and a magnetic shielding structure; 4. Cooling and demolding After hot pressing, the intermediate mold is cooled by a heat dissipation mechanism, and then the demolding mechanism separates the finished product from the intermediate mold, completing the cycle.

[0004] However, most of the existing T-Core inductor hot-press packaging machines use water cooling for cooling. However, water cooling structures have the following defects when in use: insufficient sealing of the interface between the cooling pipe and the mold can lead to coolant leakage, which not only pollutes the production environment, but may also leave moisture inside the inductor, causing short circuits or corrosion.

[0005] Therefore, this application provides an automated feeding mechanism for hot pressing molds for inductors. Summary of the Invention

[0006] The purpose of this application is to solve at least one technical problem raised in the background art.

[0007] This application provides an automated feeding mechanism for hot pressing molds for inductors, including a hot pressing mechanism and a cooling mechanism.

[0008] The hot pressing mechanism includes a base, a protective cover fixedly installed on the upper surface of the base, a pushing component and a hot pressing head respectively disposed inside the protective cover, a slide rail fixedly installed on the upper surface of the base, and an inductive hot pressing die slidably fitted inside the slide rail. The base is provided with a positioning component for positioning the inductive hot pressing die.

[0009] By adopting the above technical solution, the inductive hot pressing die filled with powder and preheated is conveyed to the slide by an external conveying mechanism. Then, the inductive hot pressing die can be conveyed to the positioning component by the pushing component on the right side. The positioning component can be used to position the inductive hot pressing die. Then, the hot pressing head is driven to descend to hot press the inductive hot pressing die.

[0010] Preferably, the cooling mechanism includes a base, a rotating disk rotatably fitted on the upper surface of the base, three limiting frames fixedly installed in a circumferential array on the upper end of the rotating disk, an air duct cooling component disposed on the upper end of the rotating disk, and a cooling air duct disposed inside the inductive hot pressing mold. The base is provided with a driving component for driving the rotating disk to rotate, and the limiting frames are adapted to the inductive hot pressing mold.

[0011] Preferably, the base has a clearance groove on the right side for the rotating disk to pass through, and a guide plate is fixedly installed on the upper surface of the slide.

[0012] By adopting the above technical solution, the limiting frame and guide plate are used to guide the inductor hot pressing mold. After the hot pressing is completed, the pushing component on the left side is driven to transport the hot-pressed inductor hot pressing mold to the limiting frame on the rotating disk. Then, the air cooling component is used to cool the inductor hot pressing mold. After that, the cooled inductor hot pressing mold can be transported to the next process by an external robot.

[0013] Preferably, the pushing component has two sets and is symmetrically arranged on both sides of the positioning component. It includes a mounting bracket fixedly installed on the inner wall of the protective cover, a ball screw rotatably installed on the inner wall of the mounting bracket, a nut seat that is helically driven by the ball screw, a first cylinder fixedly installed at the lower end of the nut seat, a pushing plate fixedly installed at the lower end of the first cylinder, and a first motor fixedly installed on one side of the mounting bracket for driving the ball screw to rotate. The mounting bracket is provided with a guide component. The upper surface of the inductive hot pressing die is symmetrically provided with two sets of positioning holes. The lower end of the pushing plate is fixedly installed with a limit pin that matches one set of positioning holes.

[0014] Preferably, the guiding assembly includes guide rods symmetrically fixedly installed on the inner wall of the mounting frame, guide sleeves slidably fitted on the surface of the guide rods, telescopic cylinders fixedly installed on the outer surface of the guide sleeves, and telescopic rods slidably fitted on the inner wall of the telescopic cylinders. The lower end of the telescopic rods is fixedly connected to the upper surface of the pusher plate, and a reinforcing rod is fixedly installed on the surface of the telescopic rods. The lower end of the reinforcing rods is fixedly connected to the upper surface of the pusher plate.

[0015] By adopting the above technical solution, driving the first cylinder to descend can drive the limit pin on the pusher plate to insert into the positioning hole on the inductive hot pressing die. At this time, the telescopic rod will slide inside the telescopic cylinder. Then, driving the first motor can drive the ball screw to rotate. By using the ball screw and nut seat for helical transmission, the guide sleeve can be driven to slide along the surface of the guide rod, which in turn can drive the pusher plate to push the inductive hot pressing die to move. The reinforcing rod is used to improve the stability of the pusher plate.

[0016] Preferably, the positioning component includes a cavity formed in the inner wall of the base, a second cylinder fixedly installed in the inner wall of the cavity, a positioning plate fixedly installed in the telescopic end of the second cylinder, and two sets of positioning pins symmetrically fixedly installed in the upper part of the positioning plate, wherein the two sets of positioning pins are adapted to two sets of positioning holes, and the upper surface of the base is symmetrically provided with two sets of through holes for the two sets of positioning pins to pass through.

[0017] By adopting the above technical solution, when the pushing component delivers the inductive hot pressing die to the point where the positioning hole and the through hole coincide, the second cylinder is driven to rise, thereby driving the positioning pin on the positioning plate to extend out of the through hole and insert into the positioning hole on the inductive hot pressing die, thereby positioning the inductive hot pressing die.

[0018] Preferably, the driving component includes a second motor fixedly mounted on the inner wall of the base, a spur gear fixedly mounted on the output end of the second motor, and a gear ring fixedly mounted on the lower end of the rotating disk, wherein the gear ring meshes with the spur gear for transmission.

[0019] By adopting the above technical solution, the second motor can drive the spur gear to rotate. The spur gear meshes with the gear ring to drive the rotating disk to rotate, thereby allowing the three limiting frames to rotate one by one to align with the slide rail, which facilitates the inductive hot pressing die to be transported from the slide rail to the limiting frame.

[0020] Preferably, the air duct cooling component includes an air inlet pipe and an exhaust pipe respectively fixedly installed on the surface of the limiting frame, and an air slip ring disposed on the upper end of the rotating disk. One end of the air inlet pipe and the exhaust pipe are respectively connected to an air supply pipe and an air return pipe. One end of the air supply pipe and the air return pipe are connected to an external cooling system through the air slip ring. Air duct sealing components are provided inside the air inlet pipe and the exhaust pipe.

[0021] Preferably, the airway blocking component includes a blocking ring fixedly installed on the inner wall of the intake pipe and the exhaust pipe, a sliding rod slidably fitted on the inner wall of the blocking ring, a baffle fixedly installed on one end of the sliding rod, blocking blocks fixedly installed in a circumferential array on one end of the baffle, and air holes opened on the surface of the blocking ring that are adapted to the blocking blocks. A push plate is fixedly installed on the other end of the sliding rod, and a return spring is sleeved on the surface of the sliding rod. The two ends of the return spring abut against the opposite surfaces of the push plate and the blocking ring, respectively.

[0022] By adopting the above technical solution, the air slip ring can be used to avoid the air supply pipe and air return pipe from getting tangled when the rotating disk rotates. The external cooling system can be used to supply low-temperature cold air to the air supply pipe. The return spring can drive the sealing block to insert into the air hole in the initial state, thereby preventing the low-temperature cold air from being discharged from the air inlet pipe.

[0023] Preferably, a first insert and a second insert are fixedly installed on the right end of the inductive hot pressing mold, one end of the first insert and the second insert are respectively connected to the two ends of the cooling air passage, and a support frame is fixedly installed on the inner wall of the first insert and the second insert, and a protrusion is fixedly installed in the middle of the support frame.

[0024] Preferably, the surfaces of the first and second insertion tubes are provided with sealing rings, and the air inlet pipe and exhaust pipe allow the first and second insertion tubes to be inserted, and the surface of the support frame is provided with ventilation grooves.

[0025] By adopting the above technical solution, when the pusher component on the right side conveys the inductive hot pressing die along the slide to the limiting frame, the first and second inserts are inserted into the air inlet and exhaust pipes respectively. The sealing ring is used to improve the sealing performance. When the first and second inserts are inserted into the air inlet and exhaust pipes respectively, the protrusion will push the push plate to move and drive the sealing block to disengage from the air hole. This allows the low-temperature cold air to be transported along the air inlet to the cooling air channel to cool the hot-pressed inductive hot pressing die. After the low-temperature cold air in the cooling air channel completes the heat exchange, it will be discharged into the return air pipe along the exhaust pipe and then discharged.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The automated feeding mechanism for hot pressing molds for inductors described in this application, through a rotary disc multi-station design, and in conjunction with an air cooling component, delivers low-temperature cold air to the cooling air channels inside the hot pressing mold of the inductor, which can cool the hot pressing mold of the inductor. In addition, the three limit frames on the rotary disc can increase the residence time and cooling time of the hot pressing mold of the inductor on the rotary disc, thereby improving the cooling time and overcoming the defect of insufficient sealing of the interface between the cooling pipe and the mold in traditional water cooling mechanisms, which leads to coolant leakage.

[0027] 2. The automated feeding mechanism for hot pressing molds for inductors described in this application, by setting an air passage sealing component, allows the inductor hot pressing mold, which is located in the limiting frame, to be removed by an external robotic arm after the inductor hot pressing mold has cooled down. At this time, the protrusion will disengage from the push plate, and the reset spring will reset and drive the sealing block to insert into the air hole, thereby preventing the leakage of low-temperature cold air and saving energy.

[0028] 3. The automated feeding mechanism for hot pressing molds for inductors described in this application achieves automatic feeding and precise positioning of the hot pressing mold for inductors through the coordinated work of the pushing component and the positioning component. The matching design of the limiting frame and the hot pressing mold for inductors, combined with the guidance of the guide plate, ensures that the hot pressing mold for inductors rotates stably on the rotary table.

Detailed Implementation

[0031] The following combination Figures 1 to 11 This application will be described in further detail below.

[0032] Example 1 Please refer to the following carefully. Figures 1 to 4 An automated feeding mechanism for an inductor hot pressing mold includes a hot pressing mechanism 100 and a cooling mechanism 200. The hot pressing mechanism 100 includes a base 101, a protective cover 102 fixedly installed on the upper surface of the base 101, a pushing component 300 and a hot pressing head 103 respectively disposed inside the protective cover 102, a slide rail 104 fixedly installed on the upper surface of the base 101, and an inductor hot pressing intermediate mold 105 slidably fitted inside the slide rail 104. The base 101 is provided with a positioning component 400 for positioning the inductor hot pressing intermediate mold 105.

[0033] Specifically, the inductive hot pressing die 105, which is filled with powder and preheated, is conveyed into the slide 104 by an external conveying mechanism. Then, the inductive hot pressing die 105 is conveyed to the positioning member 400 by the pushing member 300 on the right side. The positioning member 400 can position the inductive hot pressing die 105. Then, the hot pressing head 103 is driven down to perform hot pressing on the inductive hot pressing die 105.

[0034] Please refer to this carefully. Figures 3 to 5 ,as well as Figure 8The pusher component 300 has two sets, symmetrically arranged on both sides of the positioning component 400. It includes a mounting bracket 301 fixedly mounted on the inner wall of the protective cover 102, a ball screw 302 rotatably mounted on the inner wall of the mounting bracket 301, a nut seat 303 screw-driven by the ball screw 302, a first cylinder 304 fixedly mounted on the lower end of the nut seat 303, a pusher plate 305 fixedly mounted on the lower end of the first cylinder 304, and a first motor 306 fixedly mounted on one side of the mounting bracket 301 to drive the ball screw 302 to rotate. A guide assembly is provided inside the mounting bracket 301, and the upper surface of the inductive hot pressing die 105 is symmetrically opened... Two sets of positioning holes 307 are provided. The lower end of the pusher plate 305 is fixedly installed with a limiting pin 308 that matches one set of positioning holes 307. The guide assembly includes guide rods 309 symmetrically fixedly installed on the inner wall of the mounting frame 301, guide sleeves 310 slidably fitted on the surface of the guide rods 309, telescopic cylinders 311 fixedly installed on the outer surface of the guide sleeves 310, and telescopic rods 312 slidably fitted on the inner wall of the telescopic cylinders 311. The lower end of the telescopic rods 312 is fixedly connected to the upper surface of the pusher plate 305. A reinforcing rod 313 is fixedly installed on the surface of the telescopic rods 312. The lower end of the reinforcing rods 313 is fixedly connected to the upper surface of the pusher plate 305.

[0035] Specifically, driving the first cylinder 304 down causes the limiting pin 308 on the pusher plate 305 to insert into the positioning hole 307 on the inductive hot pressing die 105. At this time, the telescopic rod 312 will slide inside the telescopic cylinder 311. Then, driving the first motor 306 can drive the ball screw 302 to rotate. By using the helical transmission between the ball screw 302 and the nut seat 303, the guide sleeve 310 can be driven to slide along the surface of the guide rod 309, which in turn can drive the pusher plate 305 to push the inductive hot pressing die 105 to move. The reinforcing rod 313 is used to improve the stability of the pusher plate 305.

[0036] Please refer to this carefully. Figure 3 , Figure 6 and Figure 8 The positioning component 400 includes a cavity formed in the inner wall of the base 101, a second cylinder 401 fixedly installed in the inner wall of the cavity, a positioning plate 402 fixedly installed in the telescopic end of the second cylinder 401, and two sets of positioning pins 403 symmetrically fixedly installed in the upper end of the positioning plate 402. Both sets of positioning pins 403 are adapted to two sets of positioning holes 307. The upper surface of the base 101 is symmetrically provided with two sets of through holes for the two sets of positioning pins 403 to pass through.

[0037] Specifically, when the pushing component 300 conveys the inductive hot pressing die 105 to the position hole 307 coinciding with the through hole, the second cylinder 401 is driven to rise, thereby driving the positioning pin 403 on the positioning plate 402 to extend out of the through hole and insert into the positioning hole 307 on the inductive hot pressing die 105, thereby positioning the inductive hot pressing die 105.

[0038] Please refer to this carefully. Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 11 The cooling mechanism 200 includes a base 201, a rotating disk 202 rotatably fitted on the upper surface of the base 201, three limiting frames 203 fixedly mounted in a circular array on the upper end of the rotating disk 202, an air duct cooling component 600 disposed on the upper end of the rotating disk 202, and a cooling air duct 204 disposed inside the inductive hot pressing mold 105. The base 201 is provided with a driving component 500 for driving the rotating disk 202 to rotate. The limiting frames 203 are adapted to the inductive hot pressing mold 105. The right side of the base 101 is provided with a clearance groove for the rotating disk 202 to pass through. A guide plate is fixedly mounted on the upper surface of the slide 104. The driving component 500 includes a second motor 501 fixedly mounted on the inner wall of the base 201, a spur gear 502 fixedly mounted on the output end of the second motor 501, and a gear ring 503 fixedly mounted on the lower end of the rotating disk 202. The gear ring 503 meshes with the spur gear 502 for transmission.

[0039] Specifically, the second motor 501 drives the spur gear 502 to rotate. The spur gear 502 meshes with the gear ring 503 to drive the rotating disk 202 to rotate, thereby allowing the three limiting frames 203 to rotate one by one to align with the slide rail 104. This facilitates the transport of the inductive hot pressing die 105 from the slide rail 104 to the limiting frame 203. The limiting frame 203, together with the guide plate, guides the inductive hot pressing die 105. After hot pressing is completed, the pusher component 300 on the left side is driven to transport the hot-pressed inductive hot pressing die 105 to the limiting frame 203 on the rotating disk 202. Then, the air cooling component 600 is used to cool the inductive hot pressing die 105. Finally, an external robot arm can be used to transport the cooled inductive hot pressing die 105 to the next process.

[0040] Please refer to this carefully. Figure 7 and Figure 8The air duct cooling component 600 includes an intake pipe 601 and an exhaust pipe 602, which are respectively fixedly installed on the surface of the limiting frame 203, and an air slip ring 603 disposed on the upper end of the rotating disk 202. One end of the intake pipe 601 and the exhaust pipe 602 are respectively connected to an air supply pipe 604 and an air return pipe 605. One end of the air supply pipe 604 and the air return pipe 605 are connected to an external cooling system through the air slip ring 603. An air duct sealing component 700 is provided inside both the intake pipe 601 and the exhaust pipe 602. The right end of the inductive hot pressing intermediate mold 105 is respectively fixedly installed with... There is a first insertion tube 708 and a second insertion tube 709. One end of the first insertion tube 708 and the second insertion tube 709 are respectively connected to the two ends of the cooling air passage 204. The inner walls of the first insertion tube 708 and the second insertion tube 709 are fixedly installed with a support frame 710. A protrusion 711 is fixedly installed in the middle of the support frame 710. The surfaces of the first insertion tube 708 and the second insertion tube 709 are provided with sealing rings 712. The air inlet pipe 601 and the exhaust pipe 602 allow the first insertion tube 708 and the second insertion tube 709 to be inserted. The surface of the support frame 710 is provided with ventilation grooves.

[0041] Specifically, the air slip ring 603 can prevent the air supply pipe 604 and the air return pipe 605 from getting tangled when the rotating disk 202 rotates. The external cooling system can supply low-temperature cold air to the air supply pipe 604. When the pusher component 300 on the left side conveys the inductive hot pressing mold 105 along the slide 104 into the limiting frame 203, the first insertion tube 708 and the second insertion tube 709 are inserted into the air inlet pipe 601 and the exhaust pipe 602 respectively. The sealing ring 712 is used to improve the sealing performance.

[0042] The working principle of this embodiment is as follows: An external conveying mechanism transports the preheated and powder-filled inductive hot-pressing die 105 into the slide rail 104. Then, the first cylinder 304 on the right side descends, causing the limit pin 308 on the pusher plate 305 to insert into the positioning hole 307 on the inductive hot-pressing die 105. Subsequently, the first motor 306 on the right side drives the ball screw 302 to rotate. Through the helical transmission between the ball screw 302 and the nut seat 303, the guide sleeve 310 slides along the surface of the guide rod 309, driving the pusher plate 305 to push the inductive hot-pressing die 105. When the pusher component 300 pushes the inductive hot-pressing die 105... When the material is conveyed to the positioning hole 307 and the through hole, the second cylinder 401 is driven to rise, thereby causing the positioning pin 403 on the positioning plate 402 to extend out of the through hole and insert into the positioning hole 307 on the inductive hot pressing die 105. Then, the pusher component 300 on the right side is driven to reset, thereby positioning the inductive hot pressing die 105. Next, the hot pressing head 103 is driven to descend and hot press the inductive hot pressing die 105. After hot pressing is completed, the first motor 306 on the left side is driven to move the pusher plate 305 to the position of the positioning component 400. Then, the first cylinder 304 on the left side is driven to descend and... The limiting pin 308 on the pusher plate 305 is inserted into the positioning hole 307 on the inductive hot pressing die 105. Then, the second cylinder 401 descends, thereby driving the positioning pin 403 to disengage from the positioning hole 307 on the inductive hot pressing die 105. Afterward, the first motor 306 on the left side is driven to rotate, moving the pusher plate 305 and the inductive hot pressing die 105 into the limiting frame 203. At this time, the first insertion tube 708 and the second insertion tube 709 will be inserted into the air inlet pipe 601 and the exhaust pipe 602 respectively, so that the low-temperature cold air can be transported along the air inlet pipe 601 to the cooling air channel 204 to heat the hot-pressed inductive hot pressing die 105. After the low-temperature cold air in the cooling air passage 204 completes heat exchange, it will be discharged into the return air pipe 605 along the exhaust pipe 602 and then discharged. Through the multi-station design of the rotating disk 202, in conjunction with the air passage cooling component 600, low-temperature cold air is delivered to the cooling air passage 204 inside the inductive hot pressing mold 105, which can cool the inductive hot pressing mold 105. In addition, the three limit frames 203 on the rotating disk 202 can increase the residence and cooling time of the inductive hot pressing mold 105 on the rotating disk 202, improve the cooling time, and overcome the defect of insufficient sealing of the interface between the cooling pipe and the mold in the traditional water cooling mechanism, which leads to coolant leakage.

[0043] Example 2 Compared with Embodiment 1, another implementation of this application is as follows: Please refer to this carefully. Figures 8 to 11The airway blocking component 700 includes a blocking ring 701 fixedly installed on the inner walls of the intake pipe 601 and the exhaust pipe 602, a sliding rod 702 slidably fitted on the inner wall of the blocking ring 701, a baffle 703 fixedly installed on one end of the sliding rod 702, blocking blocks 704 fixedly installed in a circumferential array on one end of the baffle 703, and air holes 705 opened on the surface of the blocking ring 701 that are adapted to the blocking blocks 704. A push plate 706 is fixedly installed on the other end of the sliding rod 702, and a return spring 707 is sleeved on the surface of the sliding rod 702. The two ends of the return spring 707 abut against the opposite surfaces of the push plate 706 and the blocking ring 701, respectively.

[0044] Specifically, in its initial state, the return spring 707 can drive the sealing block 704 to insert into the air hole 705, thereby preventing the low-temperature cold air from being discharged from the air intake pipe 601. When the first insertion tube 708 and the second insertion tube 709 are respectively inserted into the air intake pipe 601 and the exhaust pipe 602, the protrusion 711 will push the push plate 706 to move and drive the sealing block 704 to disengage from the air hole 705, so that the low-temperature cold air can be transported along the air intake pipe 601 to the cooling air passage 204 to cool the hot-pressed inductive hot-pressing mold 105. After the low-temperature cold air in the cooling air passage 204 completes the heat exchange, it will be discharged along the exhaust pipe 602 into the return air pipe 605 and discharged.

[0045] The working principle of this embodiment is as follows: When the first insertion tube 708 and the second insertion tube 709 are respectively inserted into the air intake pipe 601 and the exhaust pipe 602, the protrusion 711 will push the push plate 706 to move and drive the sealing block 704 to disengage from the air hole 705. This allows the low-temperature cold air to be transported along the air intake pipe 601 to the cooling air channel 204 to cool the hot-pressed inductive hot-pressing mold 105. After the inductive hot-pressing mold 105 has cooled down, the inductive hot-pressing mold 105 in the limiting frame 203 can be removed by an external robotic arm. At this time, the protrusion 711 will disengage from the push plate 706, and the reset spring 707 will reset and drive the sealing block 704 to insert into the air hole 705, thereby preventing the leakage of low-temperature cold air and saving energy.
