Description

[0002] With the development of electronic products towards miniaturization and integration, as one of the key components, inductors are facing higher requirements. Modern inductors not only need to have the characteristics of miniaturization, low DC impedance, and minimum loss, but also need to be able to carry large currents and ensure high reliability. To meet these requirements, it is urgent to improve the quality of inductor production.

[0003] Traditional inductor production processes usually rely on manual or semi-automatic operations, which are not only inefficient, but also some traditional production lines lack effective die quality inspection and treatment mechanisms, and cannot timely identify and repair die defects caused by material shortage or accumulation, ultimately affecting product quality. In addition, the dies of traditional production lines will inevitably be contaminated with residues, dust, and sundries during the recycling process, affecting the appearance and performance of products.

[0055] In order to make the content of the present invention easier to be clearly understood, the present invention will be further described below according to specific embodiments in combination with the accompanying drawings.

[0056] It should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. used in this article is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0057] Unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] In view of the problems in the background art, the inductive hot pressing production line proposed by the present invention includes:

[0059] A machine table 1, on which there are successively arranged, according to the process, an implanting module 2 for loading semi-finished workpieces into a mold, a powder filling module 3 for loading glue-containing iron powder into the mold, a preheating module 4 for preheating the mold to the glue activation temperature, a multi-station hot pressing module 5 for hot pressing the preheated mold, a cooling module 6 for cooling the hot-pressed mold and the finished product, and a demolding module 7 for separating the cooled mold and the product;

[0060] Each of the above modules is provided with a handling structure 12 for transferring the mold between the modules. Between the implanting module 2 and the powder filling module 3, there is also provided a stacked material detection mechanism 9 for detecting the stacked materials of the mold after implantation and an NG mold processing mechanism for cleaning the unqualified molds. And there is also provided a transfer mechanism for transferring the qualified molds to the powder filling module 3 and transferring the powder-filled molds to the preheating module 4;

[0061] On the machine table 1, there is also provided a mold cleaning mechanism 8 docked at the outlet side of the demolding module 7 for cleaning the demolded mold. Between the stacked material detection mechanism 9 and the NG mold processing mechanism 11, there is a moving module 10 for moving the unqualified molds to the NG mold processing mechanism, and the moving module 10 is docked at the mold cleaning mechanism 8 and the implanting module 2 for moving the cleaned mold to the implanting module 2.

[0062] With reference to Figures 1 to 13As shown, in this embodiment, the machine table 1 serves as the core support structure of the entire production line. It is usually made of metal materials such as steel or aluminum alloy, with sufficient rigidity and stability to carry various components and transmit necessary mechanical effects. This equipment is mainly applied in the hot pressing and encapsulation stage. Among them, the semi-finished workpiece refers to the inductance semi-finished product that has been wound, and the mold is composed of a middle template and a middle mold base. By integrating multiple functional modules on the machine table 1, including the implanting module 2, the powder filling module 3, the preheating module 4, the hot pressing module, the cooling module 6, and the demolding module 7, it covers multiple process steps from semi-finished product loading, glue powder filling, preheating, hot pressing, cooling to demolding. Each module can independently complete its own tasks according to the process requirements. At the same time, a handling structure 12 and a transfer mechanism are provided. Each handling structure 12 is a linear drive module and a pawl manipulator arranged inside the module station, and the transfer mechanism is a four-segment structure, which includes a rotating disk driven by a hollow reducer driven by a servo motor. Mold fixing platforms are arranged at 4 90° positions on the disk, and the mold is pushed and pulled in and out by the pawl to ensure that the mold can move smoothly along the working direction of each module. This design enables the entire production process to achieve a high degree of automation, significantly reducing the need for manual operations and improving the operation efficiency of the production line.

[0063] Furthermore, as Figure 1As shown in the figure, there are two parallel conveying tracks extending in the Y-axis direction on the end face of the machine platform 1 as the moving module 10. The right one is the first track, and the left one is the second track. A stacking detection mechanism 9 is arranged at the connection position of the bottom ends of the first track and the second track. After the module passes through the CCD detection in the stacking detection mechanism 9 from the top of the first track, it is ensured that the die cavities are free of damage and dirt. Then it moves to the second track, and through the handling structure 12 in the implant module 2, the die to be implanted is moved into the implant module 2, and the wound inductors are implanted into the die cavities. After being filled, the die returns to the first track and passes through the stacking detection mechanism 9 again for post-implantation stacking detection, which can check whether there is a shortage or accumulation of implanted materials inside the die, avoiding defective products. If the die is detected to be defective after implantation at this time, the die will move along the first track to the top NG die processing mechanism 11, and the implanted materials inside the unqualified die cavities will be emptied through the NG processing structure, and then return to the inside of the implant module 2 along the previous path for re-implantation. The qualified die detected is rotated by the transfer mechanism on the right side of the stacking detection mechanism 9 above the powder filling module 3. In this module, the die is filled with an appropriate amount of glue-containing iron powder. After powder filling is completed, the transfer mechanism rotates the die into the preheating module 4 on its right side. The preheating module 4 specifically includes a preheating track extending in the X-axis direction. A plurality of heating components are installed beside the track, and a heat insulation cover is covered above the track to form a preheating tunnel. In this preheating tunnel, the handling manipulator pushes the die to the right, heating the inductor semi-finished products and glue-containing iron powder in the die to the temperature at which the glue is activated, and then enters the multi-station hot pressing module 5. The multi-station hot pressing module 5 is a 14-station hot press, and its function is to cure the preheated inductor semi-finished products and glue-containing iron powder under certain temperature and pressure. The die after hot pressing then enters the cooling module 6. The cooling module 6 is a cooling tunnel parallel to the preheating tunnel, which can effectively cool the die and products after hot pressing. After cooling is completed, the die enters the demolding module 7 for demolding treatment to separate the cooled die from the products. At the end of the demolding module 7, there is a die cleaning mechanism. Through the handling structure 12 of this mechanism, the die is moved to the cleaning station for cleaning treatment. The cleaned die will be moved to the moving module 10, and after CCD detection, it returns to the implant module 2 to complete a complete cycle process.

[0064] The stacking detection mechanism 9 of the present embodiment includes a stacking detection probe 91, one end of which is provided with an insulating detection part 911, and the insulating detection part 911 is provided with a sensing part 912 and a connecting part 913 in sequence along the extension direction of the stacking detection probe 91, an insulating plate is provided between the outer periphery of the connecting part 913 and the outer periphery of the sensing part 912, the connecting part 913, the insulating plate and the sensing part 912 are enclosed to form an isolation space, the end surface of the connecting part 913 facing away from the sensing part 912 is provided with a connecting seat 914, the connecting seat 914 and the connecting part 913 are enclosed to form a test space, a short-circuit part 915 is penetrated in the connecting part 913, and the short-circuit part 915 is penetrated in the isolation space, the sensing part 912 is provided with a stacking detection part 916 corresponding to the short-circuit part 915, and the short-circuit part 915 is provided with a reset structure 917 relative to the stacking detection part 916. And also includes a lifting structure 92, the lifting structure 92 is fixed on the machine platform 1 and connected to the stacking detection probe 91, and is used to drive the stacking detection probe 91 to approach the mold for detection.

[0065] Combined with reference Figure 2 and Figure 3 As shown, in this embodiment, the test space formed by the connection part 913 and the connection seat 914 can be adapted to the mold to be tested and the semi-finished workpiece above it. An insulating plate is provided between the connection part 913 and the sensing part 912 to prevent the two from directly contacting each other. In addition, the provision of the isolation space can effectively prevent the connection part 913 from contacting the sensing part 912 when there is no stacking of materials in the mold, thereby preventing test errors caused by contact. Through this structural design, the accuracy of the detection can be ensured and the waste of semi-finished workpieces due to test errors can be avoided. Specifically, a short-circuit part 915 is provided inside the connection part 913, and a stacking detection part 916 is provided in the sensing part 912. The short-circuit part 915 and the stacking detection part 916 are connected by a reset structure 917, and the reset structure 917 usually adopts a spring device. When there is no material overlap on the mold, the lifting structure 92 will drive the material overlap detection mechanism 9 to move down, the test space will expand around the mold, and the short-circuit portion 915 will be connected to the semi-finished workpiece on the mold. At this time, the short-circuit portion 915 will not contact the material overlap detection portion 916, so no material overlap signal will be output. However, when material overlap occurs on the mold, due to the increase in the thickness of the semi-finished workpiece, the short-circuit portion 915 will rise steadily under the action of the spring structure, and pass through the isolation space to contact the material overlap detection portion 916, thereby causing the material overlap detection portion 916 to short-circuit and send out a material overlap signal. In this way, the subsequent equipment can promptly identify the problem of the detected mold, and transfer the unqualified mold to the NG mold processing mechanism 11 through the mobile module 10. At the same time, the qualified mold will be sent to the powder filling module 3 for subsequent processing through the transfer mechanism. Through the above-mentioned structural design, not only the accuracy of the detection is improved, but also the misjudgment caused by the problem of material overlap can be effectively avoided, thereby ensuring the smooth progress of the production process.

[0066] The NG mold processing mechanism of this embodiment includes a mounting frame 111, on which a moving platform 112 and a flipping unit 113 are provided. The flipping unit 113 is parallel to the moving platform 112 and is provided with a limiting chute 114 relative to the driving mechanism. The end face of the flipping unit 113 facing away from the limiting chute 114 is provided with a punch 115, and the mounting frame 111 is provided with a receiving box 116 facing the flipping unit 113.

[0067] With reference to Figure 4 and Figure 5 As shown, in this embodiment, the overall structure of the NG mold processing mechanism includes a mounting frame 111 and a flipping unit 113. The flipping unit 113 can quickly send the molds that fail the inspection into the flipping unit 113 through the handling structure 12 located in the working station, and can take the molds out again after the processing is completed, and place them in the moving module 10 to return to the implanting machine. The driving system of the flipping unit 113 consists of driving parts such as motors and cylinders, and can take out the semi-finished workpieces from the molds by rotating 180°. This design effectively improves the speed and efficiency of mold cleaning, and thus improves the product quality. In addition, the design of the limiting chute 114 can ensure that the molds will not fall off from the flipping unit 113 during the flipping process, thus ensuring the stable processing of the molds. A receiving box 116 is provided on one side of the mounting frame 111 facing the flipping unit 113, which can quickly and stably recycle the semi-finished workpieces disassembled from the molds, avoiding waste caused by failure to recycle in time. And a punch 115 is provided at one end of the flipping unit 113 facing away from the limiting chute 114. The punch 115 is driven by a cylinder and can hit the semi-finished workpieces through the back of the mold to ensure that all semi-finished workpieces are smoothly disassembled from the molds. Through this series of designs, the cleaning process of the NG molds is more efficient and stable, and at the same time, the recycling efficiency and quality of the molds are improved.

[0068] The implantation module 2 of this embodiment has two sets, and is symmetrically arranged on the end surface of the machine 1, including a placement seat 21, a feeding mechanism 22 and an implantation mechanism 23. The placement seat 21 is used to place and position the mold. The feeding mechanism 22 includes a vibration plate 221 fixed on the machine 1 and a moving assembly 222. The vibration plate 221 has a feeding belt 223. The moving assembly 222 is arranged at the end of the feeding belt 223. The moving assembly 222 is provided with a plurality of accommodating holes for accommodating semi-finished workpieces, and the moving assembly 222 can move back and forth to move the semi-finished workpiece. To move the semi-finished workpiece, the implantation mechanism 23 includes a first movable guide rail 231 and an implantation arm 232, the implantation arm 232 is movably connected to the first movable guide rail 231 and is located above the placement seat 21, one end of the first movable guide rail 231 is connected to a first driving member 233 to drive the implantation arm 232 to move along the first movable guide rail 231, the top of the implantation arm 232 is connected to a second driving member 234 to drive the implantation arm 232 to move vertically, and the implantation arm 232 has a plurality of suction nozzles 235 for sucking the semi-finished workpiece.

[0069] Combined with reference Figure 6 and Figure 7 As shown, two sets of independent implantation modules 2 are symmetrically arranged on the upper and lower sides of the machine 1, forming two parallel production lines. At the same time, at least two molds are configured in each set of mechanisms, so that four products can be completed simultaneously in each implantation process, which greatly improves production efficiency. In addition, when one set of mechanisms fails or needs maintenance, the other set of mechanisms can still operate continuously, thus avoiding the situation where the whole machine is shut down. This dual-mechanism design can significantly increase the overall output, especially when the demand is large, and can better meet the market demand. And each implantation module 2 has two feed rails and discharge rails connected to the mobile module 10, which are used to move the mold to be implanted to the placement table through the conveying structure 12, and to take out the implanted mold.

[0070] In this embodiment, the placement base 21 provides a basic platform for fixing and supporting the mold entering the implantation station. The vibrating disk 221 is equipped with a feeding belt 223, which is a part of the conveyor belt and is used to send semi-finished workpieces to the transfer assembly 222 one by one. The transfer assembly 222 is located at the end of the feeding belt 223 and has a plurality of receiving holes for precisely receiving and handling workpieces. The transfer assembly 222 can reciprocate along the X-axis direction to accurately send the workpieces to the implantation mechanism 23. The main task of the implantation mechanism 23 is to accurately implant the workpieces into the mold. During this process, the first moving track is arranged along the Y-axis direction of the machine table 1 and mainly provides a movement track for the implantation arm 232. One end of the first moving track is close to the transfer assembly 222, so that the implantation arm 232 can receive semi-finished workpieces at this end. The first driving member 233 is installed at one end of the first moving track and is responsible for driving the implantation arm 232 to move along the Y-axis direction on the first moving track. The implantation arm 232 is a movable part that can slide on the first moving track, and its function is to accurately implant the workpieces into the mold. The top of the implantation arm 232 is connected with a second driving member 234, which can control the up and down movement of the implantation arm 232 to ensure that the semi-finished workpieces can be accurately taken out and placed into the mold. In addition, the suction nozzle 235 on the implantation arm 232 will be docked with the guiding hole of the mold, so as to ensure that the workpieces can be sucked out of the receiving holes and accurately sent into the mold.

[0071] The powder filling module 3 of this embodiment includes a cold pressing mechanism 31, a preform master mold 32, a powder feeding mechanism 33, a mounting plate 34 and a switching cylinder 35. The cold pressing mechanism 31 is fixedly arranged on the machine table 1.

There is a stamping space 313 between the upper stamping structure 311 and the lower stamping structure 312. The preform master mold 32 is arranged in the stamping space 313. The preform master mold 32 has a plurality of forming holes 321. The preform master mold 32 is slidably connected with a mold.

A first positioning track 341 is arranged above the mounting plate 34, and the preform master mold 32 is slidably connected in the first positioning track 341. A second positioning track 342 is arranged below the mounting plate 34, and the mold is slidably connected in the second positioning track 342. The switching cylinder 35 is connected to the mounting plate 34 and is drivingly connected to the preform master mold 32.

[0072] Refer to in combination Figure 8As shown in the figure, the upper stamping structure 311 and the lower stamping structure 312 of this embodiment are respectively arranged on the upper and lower sides of the precast block master mold 32, and they are the core working components of the cold press. Among them, the upper stamping structure 311 includes a driving member and an upper punch 115 connected to the driving member, and the lower stamping structure 312 is composed of two driving members, and each driving member is connected to a lower punch 115. The upper punch 115 is located above the precast block master mold 32 and is mainly used to push or apply pressure to the precast block master mold 32, while the lower punch 115 is located below the master mold and is responsible for supporting or applying pressure to the precast block master mold 32.

[0073] During the cold pressing process, the precast block master mold 32 is located in the stamping space 313 between the upper stamping structure 311 and the lower stamping structure 312, and the powder is compacted and formed into a precast block. The upper punch 115 and the lower punch 115 compress and fill the powder into the cavity of the master mold by applying pressure. The precast block master mold 32, as the core component in the cold pressing die core, its design directly determines the shape and size of the final precast block. Usually, the master mold is a mold with a cavity, and after the powder is filled, it is compacted through the stamping action to form a precast block. The sliding connection between the mold and the precast block master mold 32 can ensure that after cold pressing, the mold can smoothly enter the die core and maintain the shape of the precast block during the subsequent hot pressing process. The sliding connection is usually achieved through a guide rail or slider design to ensure the docking accuracy between the mold and the master mold. In order to ensure the precise filling of the powder, the powder feeding mechanism 33 is designed to precisely fill the powder into the precast block master mold 32.

[0074] The powder feeding mechanism 33 includes a vibration system, a conveying device (such as a screw conveyor, a pneumatic conveying system, etc.) and a powder storage device. The vibration system can help the powder to be evenly distributed into the cavity of the master mold, avoiding the phenomenon of powder accumulation or vacancy. The powder feeding mechanism 33 is connected to one side of the precast block master mold 32 so as to precisely feed the powder into the precast block master mold 32. After the filling is completed, the cold pressing process immediately starts. At this time, the upper punch 115 presses down and compacts the powder to form a precast block. After the cold pressing is completed, the upper punch 115 is lifted, and the lower punch 115 retracts. By driving the switching cylinder 35, the precast block master mold 32 is pushed backward to close the formed precast block. Next, the mold enters the second positioning track 342 and is reset by the cylinder to ensure the precise docking between the mold and the master mold. At this time, the upper punch 115 presses down again to push the closed precast block into the mold, ensuring that the precast block can smoothly enter the mold and be prepared for subsequent processing.

[0075] The multi-station hot pressing module 5 of this embodiment includes an annular frame 51 and multiple groups of hot pressing mechanisms; the annular frame 51 successively includes an upper fixing plate 511, a die holder fixing table 512, and a lower fixing plate 513 from top to bottom. A plurality of first installation spaces 514 are formed equidistantly around the central axis between the upper fixing plate 511 and the die holder fixing table 512, and a plurality of second installation spaces 515 are formed equidistantly around the central axis between the die holder fixing table 512 and the lower fixing plate 513; the hot pressing mechanism includes an upper die structure 52 located in the first installation space 514 and a lower die structure 53 located in the second installation space 515; and further includes a hot pressing control device 54 for driving each of the upper die structures 52 and the lower die structures to close and open the die simultaneously.

[0076] Referring to Figure 10 and Figure 11 As shown, the structure of the annular frame 51 successively includes an upper fixing plate 511, a die holder fixing table 512, and a lower fixing plate 513 from top to bottom, and is in the shape of a regular octagon as a whole to form a quasi-annular structure. There are certain gaps between the upper fixing plate 511 and the die holder fixing table 512, and between the die holder fixing table 512 and the lower fixing plate 513, so as to form a plurality of first installation spaces 514 and second installation spaces 515 that are equidistantly distributed and arranged around the central axis of the frame, and these spaces are vertically aligned in the up and down direction. The structure of this hot press includes seven groups of upper dies and seven groups of lower dies, which are arranged in an annular layout, and the circumference is evenly divided into eight equal parts. One of the equal parts is used as the inlet and outlet position of the die, and a total of 14 sets of dies operate simultaneously. Compared with the traditional hot press with only 2 sets of dies, the working efficiency of this model is increased by 7 times. And this annular hot press has 7 short stress rings. Compared with the existing hot press on the market with only one large stress ring, and it is an alternating stress ring, the length and span of the stress line are greatly reduced, and under the same pressure condition, the deformation displacement is greatly reduced.

[0077] Specifically, for the upper die structure 52, its upper die base is in a fixed installation state. An upper moving die is arranged above it, and an oil cylinder is fixedly installed at the top of the upper fixing plate 511 as an upper driving member. The upper moving die is driven and connected to the top of the upper moving die through a first push rod, and is driven to advance towards or away from the upper die base, so as to perform hot pressing on the die placed in the upper die base. Similarly, for the lower die structure 53, its lower die base is in a fixed state. A lower moving die is arranged below it, and an oil cylinder is fixedly installed at the bottom of the lower fixing plate 513 as a lower driving member. The lower moving die is driven and connected to the top of the lower moving die through a second push rod, and is driven to advance towards or away from the lower die base, so as to perform hot pressing on the die placed in the lower die base. A hot pressing control device 54 including a control cabinet and a hydraulic oil station is connected beside the hot press main body, which can synchronously drive the oil cylinders of each upper die structure 52 and lower die structure 53 to work, so as to drive each hot pressing mechanism to operate simultaneously, and each upper die structure 52 and lower die structure 53 move synchronously during the mold closing and mold opening processes. It can ensure that the mold fixing table 512 in the middle of the frame is balanced in force and cancels each other out up and down, without bending deformation. Furthermore, the mold frame, die base, and moving die can all be evenly stressed, so that the consistency of the height, density, and physical properties of the pressed products is greatly improved compared with the previous hot press. An insulating shell composed of six insulating plates is used to isolate the outside of the die cavities of the upper die structure 52 and the lower die structure 53, which can reduce heat dissipation during hot pressing. Through the handling mechanism located in the annular frame 51, the preheated die can be moved into the upper die structure 52 or the lower die structure 53, and the hot-pressed die can be moved to the next cooling module 6.

[0078] The demolding module 7 of this embodiment includes an operating table 71 arranged on the machine table 1, a demolding station 72 located on the operating table 71, and a demolding assembly 73. The demolding assembly 73 includes a demolding plate 731 movably arranged above the demolding station 72, a demolding pin group 732 arranged at the bottom of the demolding plate 731, and a servo electric cylinder 733. The servo electric cylinder 733 is drivingly connected to the demolding plate 731 and is used to drive the demolding plate 731 to move towards the demolding station 72, so as to push the inductor to be demolded out of the die.

[0079] Referring to Figure 12 As shown, the demolding plate 731 of this embodiment is movably arranged above the demolding station 72 and can move towards the demolding station 72 under the drive of the servo electric cylinder 733. Multiple demolding pin groups 732 are arranged at the bottom of the demolding plate. These demolding pin groups 732 are responsible for directly contacting the inductor to be demolded and pushing the inductor out of the die through the thrust force to complete the demolding operation. Because the servo mechanism is used for demolding, the demolding pressure and speed are more stable than the original air-liquid intensifying cylinder. The impact energy on the product during demolding is small, reducing the risk of product cracking and peeling during demolding. Finally, through the handling structure 12 located in the demolding module 7, the demolded die is moved to the outlet end of the operating table 71.

[0080] The mold cleaning mechanism 8 of this embodiment is docked with the demolding module 7. The mold cleaning mechanism 8 includes a bracket 81, a brush roll assembly 82, a driving assembly 83, and a dust suction assembly 84. The bracket 81 has a cleaning opening 811. The brush roll assembly 82 includes an upper brush roll 821 and a lower brush roll 822 that are vertically arranged on the cleaning opening 811. The driving assembly 83 is used to drive the upper brush roll 821 and the lower brush roll 822 to work for cleaning the mold. The dust suction assembly 84 is arranged adjacent to the cleaning opening 811 and is used to adsorb and collect the dust removed by the upper brush roll 821 and the lower brush roll 822.

[0081] Referring to Figure 13 As shown, the tight docking between the mold cleaning mechanism 8 and the demolding module 7 of this embodiment enables the middle template and the middle mold base of the mold to be cleaned immediately after the mold is demolded. The upper brush roll 821 and the lower brush roll 822 driven by the driving assembly 83 rotate, and the contact between the bristles and the mold can effectively remove the residues on the surface and in the pores of the mold, so as to achieve dust removal, decontamination, and cleaning treatment, which can improve the product quality and the mold life. And a dust suction assembly 84 is arranged on the base, which is adjacent to the cleaning opening 811 and is located on the side of the brush roll assembly 82 close to the outlet, and can adsorb the dust, debris, and other sundries removed by the brush roll in real time, avoiding the dust from flying or accumulating around the equipment, and ensuring the cleanliness and safety of the machine 1 and the operating environment.

Any non-substantial changes and modifications made by those skilled in the art based on the present invention shall fall within the protection scope of the present invention.
