[0004] During production, the implantation machine assembles the magnetic core into the hole groove of the carrier, a robot grabs the carrier with the magnetic core and transfers it from the implantation machine to the powder filling mechanism, and another robot grabs the carrier from the powder filling mechanism to the conveying line. The pushing mechanism can push the carrier transported from the conveying line into the powder filling mechanism, and push it to the conveying line again after filling with powder. At the same time, the pushing mechanism can push the carrier transported from the conveying line into the pressing machine, and the heating plate of the pressing machine heats the carrier. The pressing machine uses a hot pressing mold to press the powder on the carrier into shape, and pushes the carrier back to the conveying line again after pressing. The conveying module conveys the carrier to the cooling template, and the cooling template can cool the carrier to prevent the powder from sticking to the surface of the carrier due to the high temperature of the carrier when the powder filling mechanism fills the carrier with powder next time. The demoulding machine pushes out the magnetic core and unloads it. Finally, the conveying module moves the carrier to the reflux conveying line, and the reflux conveying line conveys the carrier to the first process.

[0041] Among them, refer to Figure 1 and Figure 2 The first mold shifting device 100 is provided with an implanting device 140, a pressing device 150, a hot pressing device 160 and a discharging device 170. The implanting device 140, the pressing device 150, the hot pressing device 160 and the discharging device 170 are arranged in sequence along the transfer route of the first loading mold 120. The implanting device 140 is used to implant the first magnetic core into the first loading mold 120.

[0042] It should be noted that the first magnetic core may be a T-Core. Of course, the shape of the first magnetic core may also be other forms.

[0043] Specifically, refer to Figure 7 The first mold shifting device 100 includes a manipulator 180 and a clamping jaw 190 connected to the free end of the manipulator 180 . The manipulator 180 sequentially arranges a pressing device 150 , a hot pressing device 160 and a discharging device 170 along its horizontal rotation direction. The clamping jaw 190 is used to transfer the first loading mold 120 .

[0044] The manipulator 180 may be a multi-axis manipulator 180, which drives the clamp 190 to move in multiple axes. The clamp 190 can clamp the first loading mold 120, so that the first loading mold 120 can be cyclically transferred between the implantation device 140, the pressing device 150, the hot pressing device 160 and the discharge device 170.

[0045] Moreover, the robot 180 sequentially arranges the pressing device 150, the hot pressing device 160 and the discharging device 170 along the horizontal rotation direction thereof, which is beneficial to reducing the floor space of the equipment.

[0046] In some embodiments of the present invention, referring to Figure 3 and Figure 4 The implantation device 140 includes a conveying mechanism, an arranging mechanism and an implantation mechanism. The conveying mechanism is used to convey the first magnetic core to the arranging mechanism. The arranging mechanism has a plurality of side-by-side material channels 210. The plurality of side-by-side material channels 210 are arranged with the first magnetic core from the conveying mechanism. The implantation mechanism is used to implant the first magnetic core of the material channel 210 into the first loading mold 120.

[0047] It should be noted that the first loading mold 120 is provided with a receiving cavity for receiving the first magnetic core, and a plurality of receiving cavities are provided. The plurality of receiving cavities are arranged in a rectangular array on the top surface of the first loading mold 120 .

[0048] Specifically, the conveying mechanism includes a vibration plate 200 and a linear motor module that drives the vibration plate 200 to move horizontally. Thus, driven by the linear motor module, the vibration plate 200 can convey the first magnetic core to each material channel 210 .

[0049] The implanting mechanism includes a material taking component 220 for taking products and a moving component 230 for driving the material taking component 220 to move. The material taking component 220 is used to implant a plurality of products from the material channel 210 into the accommodating cavity.

[0050] Furthermore, the implantation mechanism also includes a material storage plate 240, which is located on the side of the first loading mold 120 close to the first material channel 210, and the material storage plate 240 has a material storage cavity for storing products, and the material storage cavity is provided with a plurality of material storage cavities, and the plurality of material storage cavities are arranged in an array. The material picking component 220 includes a first adsorption head 250 and a second adsorption head 260, and the first adsorption head 250 is used to transfer the product positioning groove 530 to the material storage cavity, and the second adsorption head 260 is used to implant the product from the material storage cavity into the accommodating cavity.

[0051] It should be noted that a positioning seat 270 is provided below the first carrier mold 120 , and the first carrier mold 120 can be placed on the positioning seat 270 to ensure that the first magnetic core can be accurately implanted, and at the same time, the robot arm 180 can correctly clamp the first carrier mold 120 .

[0052] Therefore, by using the implantation mechanism, the products at the ends of the multiple material channels 210 can be implanted into the first loading mold 120, so that there is no need to implant the first magnetic cores into the first loading mold 120 one by one, which greatly improves the implantation efficiency and meets the production needs.

[0053] Among them, refer to Figure 1 and Figure 2 The second mold shifting device 110 is provided with a powder filling device 280 and a molding device 290, which are arranged in sequence along the transfer route of the second loading mold 130. The powder filling device 280 is used to fill powder into the second loading mold 130, and the molding device 290 is used to press the powder of the second loading mold 130 out of the second magnetic core.

[0054] It should be noted that the second loading mold 130 is provided with a receiving cavity for receiving the second magnetic core. A plurality of receiving cavities are provided, and the plurality of receiving cavities are arranged in a rectangular array on the top surface of the second loading mold 130 .

[0055] The second magnetic core may be a U-Core. Of course, the shape of the second magnetic core may also be other forms.

[0056] Specifically, refer to Figure 5 The second mold shifting device 110 includes a first mold shifting mechanism 300 and a second mold shifting mechanism 330. The first mold shifting mechanism 300 includes a slider 310 and a driving member 320 for driving the slider 310 to slide horizontally. A second loading mold 130 is stacked on top of the slider 310. The slider 310 is slidably arranged between the powder filling device 280 and the molding device 290. The second mold shifting mechanism 330 is used to move the second loading mold 130 into or out of the pressing device 150.

[0057] It should be noted that the driving member 320 can use a servo motor in conjunction with a screw nut structure to drive the slider 310 to slide back and forth.

[0058] Therefore, driven by the driving member 320, the slider 310 drives the second loading mold 130 to be transferred to the powder filling device 280, and the powder filling device 280 fills the second loading mold 130 with powder. Then, the slider 310 drives the second loading mold 130 to be transferred to the molding device 290, and the molding device 290 presses the powder of the second loading mold 130 to form a second magnetic core. Then, the second mold moving mechanism 330 moves the second loading mold 130 with the second magnetic core into the pressing device 150. After the first magnetic core and the second magnetic core are pressed together, the second mold moving mechanism 330 moves the unloaded second loading mold 130 out of the pressing device 150.

[0059] More specifically, refer to Figure 6 The powder filling device 280 includes a powder box 340 and a powder outlet structure 350 disposed at the bottom of the powder box 340 . The powder box 340 contains powder, and the powder outlet structure 350 is used to fill the powder into the accommodating cavity of the second loading mold 130 .

[0060] The powder filling device 280 further includes a scraper 360 located in the powder box 340 and a motor driving the scraper 360 to rotate horizontally. The scraper 360 is used to scrape the powder into the powder outlet structure 350 .

[0061] More specifically, the molding device 290 includes a cold pressing die 370 and a hydraulic cylinder for driving the cold pressing die 370 to press downward. The cold pressing die 370 can press the powder of the second loading die 130 to form the second magnetic core.

[0062] More specifically, the second mold moving mechanism 330 can use three linear motor modules arranged in the XYZ coordinate direction as power, and cooperate with the clamping mechanism to clamp the second loading mold 130, thereby moving the second loading mold 130 into or out of the pressing device 150.

[0063] Among them, refer to Figure 1 and Figure 2 A pressing device 150 is set at the intersection of the transfer route of the first loading mold 120 and the moving route of the second loading mold 130. The pressing device 150 is used to press the second magnetic core on the second loading mold 130 into the first loading mold 120 to make the second magnetic core and the first magnetic core fit together.

[0064] Specifically, refer to Figure 8 The pressing device 150 includes a first heating seat 380, a pressing mold 390 located above the first heating seat 380, and a first power component that drives the pressing mold 390 for pressing. The first heating seat 380 is placed with a second loading mold 130 and a first loading mold 120 stacked up and down. The pressing mold 390 is used to press the second magnetic core into the first loading mold 120.

[0065] More specifically, refer to Fig. 9 Two brackets 400 are connected to the bottom of the pressing mold 390. The two brackets 400 are arranged opposite to each other and are used to support the second loading mold 130. Positioning parts 410 are respectively provided on opposite sides of the two brackets 400. The brackets 400 limit the horizontal position of the second loading mold 130 through the positioning parts 410.

[0066] It should be noted that the positioning portion 410 may be a positioning groove 530 , and the positioning portion 410 may also be in a strip shape.

[0067] It can be understood that the robot 180 stacks the first loading mold 120 on the first heating seat 380, and the second mold moving mechanism 330 places the second loading mold 130 on two brackets 400. During pressing, the first power component drives the pressing mold 390 to press down, so that the second loading mold 130 is stacked on the top surface of the first loading mold 120. Therefore, the pressing mold 390 can press the second magnetic core into the first loading mold 120, and make the second magnetic core and the first magnetic core fit together.

[0068] During the pressing process, the first heating seat 380 has an electric heating rod, which can heat and keep the first loading mold 120 warm, preparing for the subsequent first loading mold 120 to be put into the hot pressing device 160, which is beneficial to shorten the waiting time for the hot pressing device 160 to heat and raise the temperature of the first loading mold 120.

[0069] Since the first loading mold 120 and the second loading mold 130 are in contact with each other during pressing, the first loading mold 120 will transfer the less heat to the second loading mold 130. Therefore, a transfer seat 420 is provided on one side of the pressing device 150, and the second mold moving mechanism 330 transfers the second loading mold 130 to the transfer seat 420. Placing the second loading mold 130 on the transfer seat 420 is conducive to cooling, thereby facilitating the subsequent powder filling operation of the second loading mold 130 by the powder filling device 280.

[0070] After the temperature of the second loading mold 130 drops, the second mold moving mechanism 330 transfers the second loading mold 130 from the intermediate transfer seat 420 to the slider 310 .

[0071] In some embodiments of the present invention, referring to Fig.10 The hot pressing device 160 includes at least one hot pressing mechanism, which includes a second heating seat 430, a hot pressing mold 440 located above the second heating seat 430, and a second power component that drives the hot pressing mold 440 to press together. The first loading mold 120 is placed on the second heating seat 430, and the hot pressing mold 440 is used to hot press the first magnetic core and the second magnetic core to form an inductor blank.

[0072] It is understandable that, according to the production requirements of the inductor, two hot pressing mechanisms can be provided, which is beneficial to improving the pressing efficiency.

[0073] Specifically, the second heating seat 430 has a preheating zone 450 and a hot pressing zone 460 connected to the preheating zone 450. The first mold moving device 100 can push the first carrier mold 120 from the preheating zone 450 to the hot pressing zone 460. In the hot pressing zone 460, the hot pressing mold 440 is pressed with the first carrier mold 120. The second heating seat 430 is provided with a push plate mechanism 470, which is used to push the first carrier mold 120 from the hot pressing zone 460 to the preheating zone 450.

[0074] Furthermore, the second heating seat 430 has an electric heating rod, and the electric heating rod generates heat so that the preheating area 450 and the hot pressing area 460 meet the hot pressing requirements.

[0075] Furthermore, the push plate mechanism 470 includes a push plate and a cylinder that drives the push plate to move.

[0076] During the hot pressing process, the robot 180 is used to place the first loading mold 120 in the preheating zone 450. The preheating zone 450 heats the first loading mold 120 to a specified temperature. The robot 180 is then used to push the first loading mold 120 into the hot pressing zone 460. The second power component drives the hot pressing mold 440 to press down. The hot pressing mold 440 hot presses the first magnetic core and the second magnetic core to form an inductor blank. Then, the cylinder drives the push plate to move horizontally, and the push plate pushes the first loading mold 120 from the hot pressing zone 460 to the preheating zone 450.

[0077] In order to clean the residual powder on the hot pressing mold 440 , the hot pressing device 160 may be provided with a first brush assembly 480 . The first brush assembly 480 includes a first sweeping brush member and a cylinder driving the first sweeping brush member to sweep. The first sweeping brush member can sweep the hot pressing mold 440 .

[0078] In some embodiments of the present invention, referring to Fig.11 The discharge device 170 includes a third heating seat 490, a discharge mold 500 located above the third heating seat 490, and a third power component for driving the discharge mold 500 to eject. The first loading mold 120 is placed on the third heating seat 490, and the discharge mold 500 is used to eject the inductor blank of the first loading mold 120.

[0079] Specifically, refer to Fig.12 The first loading die 120 includes a support plate 510 and a loading plate 520 stacked on top of the support plate 510. The third heating seat 490 has a positioning groove 530 and a discharge groove 540 located on one side of the positioning groove 530. The positioning groove 530 is used to accommodate the support plate 510. The discharge groove 540 is used to accommodate the loading plate 520. The third heating seat 490 is provided with a plate moving mechanism 560. The plate moving mechanism 560 is used to place the loading plate 520 from the support plate 510 into the discharge groove 540. The unloading die 500 can push the inductor blank from the loading plate 520 into the discharge groove 540.

[0080] It should be noted that the third heating seat 490 is an electric heating rod, which can heat and keep the first loading mold 120 warm, preparing for the subsequent first loading mold 120 to be put into the hot pressing device 160, which is beneficial to shorten the waiting time for the hot pressing device 160 to heat and raise the temperature of the first loading mold 120.

[0081] The carrier plate 520 loads the inductor blank through the accommodating cavity, and the support plate 510 is used to prevent the inductor blank from escaping from the accommodating cavity.

[0082] When unloading, the robot 180 is used to transfer the first loading mold 120 to the positioning groove 530, and then the plate moving mechanism 560 puts the loading plate 520 into the unloading groove 540 to separate the loading plate 520 and the support plate 510. The third power component drives the unloading mold 500 to push the inductor blank in the accommodating cavity of the loading plate 520 into the unloading groove 540, thereby separating the inductor blank from the first loading mold 120.

[0083] A cleaning trough 550 is arranged on the side of the feed trough 540 away from the positioning trough 530 , and the cleaning trough 550 is provided with a second sweeping brush assembly for cleaning the carrier plate 520 . The plate moving mechanism 560 can transfer the carrier plate 520 from the feed trough 540 to the cleaning trough 550 , and the second sweeping brush assembly can clean the residual powder on the surface of the carrier plate 520 .

[0084] Similarly, the positioning groove 530 is provided with a third sweeping brush assembly for cleaning the support plate 510 .

[0085] The plate moving mechanism 560 includes a push frame and a linear motor module driving the push frame to move horizontally. The push frame includes two first push arms. The carrier plate 520 is accommodated between the two push arms and can push the carrier plate 520 .

[0086] It should be noted that the positioning groove 530 , the material discharge groove 540 and the cleaning groove 550 are interconnected, so under the drive of the linear motor module motor, the push arm can transfer the carrier plate 520 between the positioning groove 530 , the material discharge groove 540 and the cleaning groove 550 .

[0087] Therefore, the working principle of the utility model is as follows:

[0088] First, the vibration plate 200 transports the first magnetic core to a plurality of parallel material channels 210, and the first adsorption head 250 adsorbs the first magnetic core at the end of the plurality of parallel material channels 210, that is, the first adsorption head 250 can transfer a row of first magnetic cores from the material channels 210 to the storage plate 240, and then the second adsorption head 260 transfers the first magnetic cores of the array from the storage plate 240 to the first loading mold 120, and the first loading mold 120 with multiple first magnetic cores is transferred to the pressing device 150 by the robot 180.

[0089] At the same time, the slider 310 drives the second loading mold 130 to be transferred to the powder filling device 280, and the powder filling device 280 fills the second loading mold 130 with powder. Then, the slider 310 drives the second loading mold 130 to be transferred to the molding device 290, and the molding device 290 presses the powder of the second loading mold 130 to form a plurality of second magnetic cores. Then, the second mold moving mechanism 330 moves the second loading mold 130 with the plurality of second magnetic cores into the pressing device 150, so that the second loading mold 130 and the first loading mold 120 are stacked together. The pressing mold 390 can press the second magnetic core into the first loading mold 120, and make the second magnetic core and the first magnetic core fit together. After pressing, the second mold moving mechanism 330 moves the unloaded second loading mold 130 out of the pressing device 150.

[0090] Next, the robot 180 places the first loading mold 120 in the preheating zone 450, and the preheating zone 450 heats the first loading mold 120 to a specified temperature. The robot 180 then moves the first loading mold 120 into the hot pressing zone 460, and the second power component drives the hot pressing mold 440 downward. The hot pressing mold 440 hot presses the first magnetic core and the second magnetic core to form an inductor blank. Next, the push plate mechanism 470 pushes the first loading mold 120 from the hot pressing zone 460 to the preheating zone 450.

[0091] Finally, the manipulator 180 transfers the first loading mold 120 to the positioning groove 530. Then, the plate moving mechanism 560 places the loading plate 520 into the unloading trough 540 to separate the loading plate 520 and the support plate 510. The third power component drives the unloading mold 500 to push the inductor blank in the accommodating cavity of the loading plate 520 into the unloading trough 540 to separate the inductor blank from the first loading mold 120. The manipulator 180 transfers the first loading mold 120 to the implantation device 140 again.
