For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] In view of the problems in the background technology, the induction hot pressing production line proposed by the present invention comprises: A machine 1, wherein the machine 1 is provided with an implantation module 2 for placing a semi-finished workpiece into a mold, a powder filling module 3 for placing glue-containing iron powder into the mold, a preheating module 4 for preheating the mold to a 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 demoulding module 7 for separating the cooled mold from the product; Each of the modules has a transport structure 12 for transferring the mold between the modules. A stacking detection mechanism 9 for detecting the mold after implantation and an NG mold processing mechanism for cleaning unqualified molds are also provided between the implantation module 2 and the powder filling module 3. A transfer mechanism is also provided for transferring the qualified molds to the powder filling module 3 and transferring the powder-filled molds to the preheating module 4. The machine 1 is also provided with a mold cleaning mechanism 8 connected to the outlet side of the demolding module 7, which is used to clean the mold after demolding, and a movable module 10 is provided between the stacking detection mechanism 9 and the NG processing mechanism 11, which is used to move the unqualified mold to the NG mold processing mechanism, and the movable module 10 is connected to the mold cleaning mechanism 8 and the implantation module 2, and is used to move the cleaned mold to the implantation module 2.

[0024] Combined with reference Figures 1 to 13As shown, in this embodiment, the machine 1, as the core support structure of the entire production line, is usually made of metal materials such as steel or aluminum alloy, and has sufficient rigidity and stability to carry various components and transmit necessary mechanical effects. The equipment is mainly used in the hot pressing packaging stage, wherein the semi-finished workpiece refers to the wound inductor semi-finished product, and the mold is composed of a middle mold plate and a middle mold base. By integrating multiple functional modules on the machine 1, including an implantation module 2, a powder filling module 3, a preheating module 4, a hot pressing module, a cooling module 6 and a demolding module 7, it covers multiple process steps from semi-finished product loading, rubber powder filling, preheating, hot pressing, cooling to demolding. Each module can independently complete its own tasks according to the process requirements. It is equipped with a handling structure 12 and a transfer mechanism. Each handling structure 12 is a linear drive module and a claw manipulator set inside the module station, and the transfer mechanism is a four-part structure, which includes a rotating disc driven by a hollow reducer driven by a servo motor. The four 90° positions on the disc are equipped with mold fixing platforms. The claws push and pull the mold in and out to ensure that the mold can move smoothly along the working direction of each module. This design makes the entire production process highly automated, significantly reduces the need for manual operation, and improves the operating efficiency of the production line.

[0025] Further, if Figure 1As shown, there are two parallel conveying tracks extending in the Y-axis direction on the end face of the machine 1 as a moving module 10, of which the right side is the first track and the left side is the second track, and a stacking detection mechanism 9 is set at the connection position between the first track and the bottom end of the second track. The module is detected by the CCD in the stacking detection mechanism 9 from the top of the first track to ensure that the mold hole is not damaged or dirty. Then move to the second track, and move the mold to be implanted to the inside of the implant module 2 through the conveying structure 12 located in the implant module 2, and implant the wound inductor into the mold hole. The filled mold returns to the first track and passes through the stacking detection mechanism 9 again to perform the stacking detection after implantation, which can check whether the mold is implanted with missing materials or piled materials to avoid product defects. If the mold is detected to be defective after implantation, the mold will go along the first track to the top NG processing mechanism 11, and the implanted materials inside the unqualified mold hole will be emptied through the NG processing structure, and return to the implant module 2 along the previous path for re-implantation. The qualified mold is rotated to the top of the powder filling module 3 by the transfer mechanism located on the right side of the stacking detection mechanism 9, in which the mold is filled with an appropriate amount of iron powder containing glue. After the powder filling is completed, the transfer mechanism rotates the mold to the preheating module 4 located on its right side. The preheating module 4 specifically includes a preheating track extending along the X-axis direction, a plurality of heating components are installed next to 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 mold to the right side, driving the semi-finished inductor and the iron powder containing glue in the mold to heat 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 solidify the preheated semi-finished inductor and the iron powder containing glue at a certain temperature and pressure. The hot-pressed mold then enters the cooling module 6. The cooling module 6 is a cooling tunnel parallel to the preheating tunnel, which can effectively cool the hot-pressed mold and product. After cooling, the mold enters the demoulding module 7 for demoulding, and the cooled mold is separated from the product. At the tail end of the demoulding module 7, a mold cleaning mechanism is provided. Through the transport structure 12 of the mechanism, the mold is moved to the cleaning station for cleaning. The cleaned mold will be moved to the mobile module 10, and after CCD detection, it will return to the implantation module 2, completing a complete cycle process.

[0026] 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.

[0027] As shown in the reference figure, 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 stacking on the mold, the lifting structure 92 will drive the material stacking 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 stacking detection portion 916, so no material stacking signal will be output. However, when material stacking 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 stacking detection portion 916, thereby causing the material stacking detection portion 916 to short-circuit and send out a material stacking signal. In this way, the subsequent equipment can promptly identify the problem of the detected mold, and transfer the unqualified mold to the NG 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 stacking can be effectively avoided, thereby ensuring the smooth progress of the production process.

[0028] The NG mold processing mechanism of this embodiment includes a mounting frame 111, on which a moving platform 112 and a flip unit 113 are arranged. The flip unit 113 is parallel to the moving platform 112 and is provided with a limiting slide groove 114 relative to the driving mechanism. A punch 115 is provided on the end face of the flip unit 113 facing away from the limiting slide groove 114, and the mounting frame 111 is provided with a material receiving box 116 facing the flip unit 113.

[0029] As shown in the reference figure, in this embodiment, the overall structure of the NG mold processing mechanism includes a mounting frame 111 and a flip unit 113. The flip unit 113 can quickly send the unqualified mold to the flip unit 113 through the handling structure 12 located in the workstation, and can take the mold out after the processing is completed, place it in the mobile module 10 and return it to the implanter. The driving system of the flip unit 113 is composed of driving parts such as a motor and a cylinder, and can remove the semi-finished workpiece from the mold by rotating 180°. This design effectively improves the speed and efficiency of mold cleaning, thereby improving product quality. In addition, the design of the limiting slide 114 can ensure that the mold will not fall off from the flip unit 113 during the flipping process, thereby ensuring the stable processing of the mold. A receiving box 116 is provided on the side of the mounting frame 111 facing the flip unit 113, which can quickly and stably recover the semi-finished workpiece removed from the mold to avoid waste due to failure to recover in time. A punch 115 is provided at one end of the flip unit 113 away from the limiting chute 114. The punch 115 is driven by a cylinder and can hit the semi-finished workpiece through the back of the mold to ensure that all semi-finished workpieces are smoothly removed from the mold. Through this series of designs, the cleaning process of NG molds is more efficient and stable, and the recycling efficiency and quality of molds are improved.

[0030] 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.

[0031] As shown in the reference figure, 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 during each implantation process, greatly improving production efficiency. In addition, when one set of mechanisms fails or needs maintenance, the other set of mechanisms can continue to operate, thereby avoiding the situation where the entire 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.

[0032] In this embodiment, the placement seat 21 provides a basic platform for fixing and supporting the mold entering the implantation station. The vibration plate 221 is equipped with a feeding belt 223, which is a component of the conveyor belt and is used to deliver the semi-finished workpieces to the moving assembly 222 one by one. The moving assembly 222 is located at the end of the feeding belt 223 and has a plurality of accommodating holes for accurately accommodating and transporting the workpieces. The moving assembly 222 can reciprocate along the X-axis direction to accurately deliver the workpieces to the implantation mechanism 23. The main task of the implantation mechanism 23 is to accurately implant the workpiece into the mold. During this process, the first moving rail is arranged along the Y-axis direction of the machine 1, mainly providing a motion track for the implantation arm 232. One end of the first moving rail is close to the moving assembly 222, so that the implantation arm 232 can receive the semi-finished workpiece at this end. The first driving member 233 is installed at one end of the first moving rail, which is responsible for driving the implantation arm 232 to move along the Y-axis direction on the first moving rail. The implantation arm 232 is a movable component that can slide on the first moving rail, and its function is to accurately implant the workpiece into the mold. The top of the implant arm 232 is connected to a second driving member 234, which can control the implant arm 232 to move up and down, ensuring that the semi-finished workpiece can be accurately taken out and placed in the mold. In addition, the suction nozzle 235 on the implant arm 232 will dock with the guide hole of the mold, thereby ensuring that the workpiece can be sucked from the receiving hole and accurately sent into the mold.

A stamping space 313 is provided between the upper stamping structure 311 and the lower stamping structure 312. The prefabricated block mold 32 is provided in the stamping space 313.

[0034] As shown in the reference figure, the upper punch structure 311 and the lower punch structure 312 of this embodiment are respectively arranged on the upper and lower sides of the prefabricated block mother mold 32, which are the core working parts of the cold press. Among them, the upper punch structure 311 includes a driving member and an upper punch 115 connected to the driving member, and the lower punch structure 312 is composed of two driving members, each of which is connected to a lower punch 115.

Usually, the master mold is a mold with a cavity, and the powder is compacted by stamping after filling to form a prefabricated block. The sliding connection between the mold and the prefabricated block master mold 32 can ensure that after cold pressing, the mold can smoothly enter the mold core and maintain the shape of the prefabricated block during the subsequent hot pressing process. The sliding connection is usually achieved by a guide rail or a slider design to ensure the docking accuracy between the mold and the master mold. In order to ensure the accurate filling of the powder, the powder feeding mechanism 33 is designed to accurately fill the powder into the prefabricated block master mold 32.

[0036] The powder feeding mechanism 33 includes a vibration system, a conveying device (such as a screw conveyor, an air flow conveying system, etc.) and a powder storage device. The vibration system can help the powder to be evenly distributed in the mother mold cavity to avoid the phenomenon of powder accumulation or vacancies. The powder feeding mechanism 33 is connected to one side of the prefabricated block mother mold 32 so as to accurately feed the powder into the prefabricated block mother mold 32. After the filling is completed, the cold pressing process begins immediately. At this time, the upper punch 115 presses down and compacts the powder to form a prefabricated block. After the cold pressing is completed, the upper punch 115 is lifted and the lower punch 115 retreats. By switching the drive of the cylinder 35, the prefabricated block mother mold 32 is pushed back to close the formed prefabricated block. Next, the mold enters the second positioning track 342 and is reset by the cylinder to ensure the precise docking of the mold and the mother mold. At this time, the upper punch 115 presses down again to push the closed prefabricated block into the mold to ensure that the prefabricated block can enter the mold smoothly and be prepared for subsequent processing.

[0037] 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 includes an upper fixed plate 511, a mold frame fixing platform 512 and a lower fixed plate 513 from top to bottom, and a plurality of first installation spaces 514 are formed equidistantly around the central axis between the upper fixed plate 511 and the mold frame fixing platform 512, and a plurality of second installation spaces 515 are formed equidistantly around the central axis between the mold frame fixing platform 512 and the lower fixed plate 513; the hot pressing mechanism includes an upper mold structure 52 located in the first installation space 514 and a lower mold structure 53 located in the second installation space 515; and also includes a hot pressing control device 54 for driving each of the upper mold structures 52 and the lower mold structure to close and open the mold simultaneously.

[0038] As shown in the reference figure, the ring frame 51 structure includes an upper fixed plate 511, a mold frame fixing platform 512 and a lower fixed plate 513 from top to bottom, and the whole is a regular octagon to form a ring-like structure. A certain gap is left between the upper fixed plate 511 and the mold frame fixing platform 512, and between the mold frame fixing platform 512 and the lower fixed plate 513, so as to form a plurality of evenly distributed first installation spaces 514 and second installation spaces 515 arranged around the central axis of the frame, and these spaces are vertically aligned in the up and down directions. The hot press structure includes seven groups of upper molds and seven groups of lower molds, which are arranged in a ring shape, and the circumference is evenly divided into eight equal parts, one of which is used as the inlet and outlet position of the mold, and a total of 14 sets of molds are operated simultaneously. Compared with the traditional hot press equipped with only 2 sets of molds, the working efficiency of this model is increased by 7 times. Moreover, this annular hot press has 7 short stress rings, compared with the existing hot presses on the market which only have one large stress ring, and it is an alternating stress ring. The length and span of the stress line are greatly reduced. Under the same pressure conditions, the deformation displacement is greatly reduced.

[0039] Specifically, the upper mold base of the upper mold structure 52 is in a fixed installation state, and an upper movable mold is arranged above it. A cylinder is fixedly arranged at the top of the upper fixed plate 511 as an upper driving member, and the top of the upper movable mold is driven and connected by a first push rod to drive it to move toward or away from the upper mold base, so as to achieve hot pressing of the mold placed in the upper mold base. Similarly, the lower mold base of the lower mold structure 53 is in a fixed state, and a lower movable mold is arranged below it, and a cylinder is fixedly arranged at the bottom of the lower fixed plate 513 as a lower driving member, and the top of the lower movable mold is driven and connected by a second push rod to drive it to move toward or away from the lower mold base, so as to achieve hot pressing of the mold placed in the lower mold base. A hot pressing control device 54 including a control cabinet and a hydraulic oil station is connected to the side of the hot press body, which can synchronously drive the cylinders of each upper mold structure 52 and the lower mold structure 53 to work, so as to drive each hot pressing mechanism to operate simultaneously, and each upper mold structure 52 and the lower mold structure 53 move synchronously during the mold closing and mold opening processes. It can ensure that the mold frame fixing platform 512 in the middle of the frame is balanced and offset up and down, and no bending deformation will occur, so that the mold frame, mold base and movable mold can all be evenly stressed, so that the height, density and physical property consistency of the extruded product are greatly improved compared with the previous hot press. And the insulation shell composed of six insulation boards is isolated outside the mold cavity of the upper mold structure 52 and the lower mold structure 53, which can reduce heat loss during hot pressing. And through the conveying mechanism located in the annular frame 51, the preheated mold can be moved to the upper mold structure 52 or the lower mold structure 53, and the hot pressed mold can be moved to the next cooling module 6.

[0040] The demoulding module 7 of this embodiment includes an operating table 71 disposed on the machine 1, a demoulding station 72 located on the operating table 71, and a demoulding assembly 73. The demoulding assembly 73 includes a demoulding plate 731 movably disposed above the demoulding station 72, a demoulding needle group 732 disposed at the bottom of the demoulding plate 731, and a servo electric cylinder 733. The servo electric cylinder 733 is connected to the demoulding plate 731 and is used to drive the demoulding plate 731 to move toward the demoulding station 72, so as to push the inductor to be demoulded out of the mold.

[0041] As shown in the reference figure, the demoulding plate 731 of this embodiment is movably arranged above the demoulding station 72, and can move toward the demoulding station 72 under the drive of the servo electric cylinder 733, and multiple demoulding needle groups 732 are arranged at the bottom of the demoulding. These demoulding needle groups 732 are responsible for directly contacting the inductor to be demoulded, and push the inductor out of the mold through thrust to complete the demoulding operation. Due to the use of servo mechanism demoulding, the demoulding pressure and speed are more stable than the original gas-liquid booster cylinder, and the demoulding has less impact energy on the product, reducing the risk of product cracking and peeling during demoulding. Finally, the demoulding-completed mold is moved to the outlet end of the operating table 71 through the handling structure 12 located in the demoulding module 7.

[0042] The mold cleaning mechanism 8 of this embodiment is connected to the demoulding module 7, and the mold cleaning mechanism 8 includes a bracket 81, a brush roller assembly 82, a drive assembly 83 and a dust suction assembly 84. The bracket 81 has a cleaning port 811, and the brush roller assembly 82 is an upper brush roller 821 and a lower brush roller 822 which are arranged on the cleaning port 811. The drive assembly 83 is used to drive the upper brush roller 821 and the lower brush roller 822 to work to clean the mold. The dust suction assembly 84 is arranged adjacent to the cleaning port 811, and is used to absorb and collect dust removed by the upper brush roller 821 and the lower brush roller 822.

[0043] As shown in the reference figure, the mold cleaning mechanism 8 and the demoulding module 7 of this embodiment are tightly connected, so that the middle mold plate and the middle mold base of the mold can be cleaned immediately after the mold is demoulded. The upper brush roller 821 and the lower brush roller 822 driven by the driving component 83 rotate, and the contact between the bristles and the mold can effectively remove the residues on the mold surface and pores, so as to achieve dust removal, decontamination and cleaning treatment, which can improve product quality and mold life. A dust suction component 84 is provided on the base, which is adjacent to the cleaning port 811 and is located on the side of the brush roller component 82 close to the outlet, and can absorb dust, debris and other sundries removed by the brush roller in real time, so as to prevent dust from flying or accumulating around the equipment, and ensure the cleanliness and safety of the machine 1 and the operating environment.
