Description

Technical Field

[0001] This application relates to the field of automation equipment technology, and in particular to an assembly device for a TLVR inductor. Background Technology

[0002] Inductors, as a fundamental electronic component, are widely used in filtering, oscillation, delay, and notch filtering in various electronic circuits. With the miniaturization and integration of electronic devices, inductors are becoming increasingly smaller. Their internal structure typically consists of an upper casing, a lower casing, and an inductor coil sandwiched between them. During assembly, the inductor coil must first be precisely placed into the slot in the lower casing, and then the upper casing is snapped shut and pressure is applied to secure it.

[0003] Currently, in the inductor manufacturing industry, especially for the assembly and manufacturing of TLVR inductors, which consist of an upper and lower housing and a coil installed between them, the assembly process largely relies on manual labor or semi-automatic equipment. During manual assembly, operators must manually place the tiny inductor coil into the lower housing and then close the upper housing for pressing. Due to the small size and high precision requirements of inductors, manual operation is not only inefficient but also prone to defects such as improper coil placement, misaligned upper housing, and uneven pressing force, leading to poor electrical performance or damage to the product's appearance.

[0004] While some equipment on the market can automate certain stages, such as a single vibratory feeder or a single pressing mechanism, there is currently no fully automated assembly equipment that integrates multiple processes, including upper shell feeding, lower shell feeding, inductor coil feeding, assembly, and pressing, into a single unit. Existing equipment layouts cannot coordinate the flow of materials across multiple workstations with the rhythm of carrier movement. This is especially true for specific processes requiring repeated placement of shells and coils (e.g., placing the lower shell and coil first, then repeating the process to ensure the assembly of the stacked structure). Current technology cannot provide a compact and highly efficient automated solution.

[0005] Therefore, there is an urgent need to provide a device that can achieve fully automated assembly of inductors to solve the problems of low efficiency, poor accuracy, and inability to operate continuously in existing manual or semi-automatic assembly methods. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a device that can realize fully automatic assembly of inductors, so as to solve the problems of low efficiency, poor accuracy and inability to operate continuously in the existing manual or semi-automatic assembly methods.

[0007] The technical solution adopted in this invention is an assembly equipment for TLVR inductors, including a machine base, at least two sets of feeding modules and a mold conveying device. The feeding modules complete the directional conveying of the housing and the coil, and the mold conveying device realizes the sequential transfer of the platform mold between multiple workstations, thereby completing the automated assembly of the inductor.

[0008] The specific technical solution of this invention is as follows: an assembly device for TLVR inductors, comprising: a machine base; at least two sets of feeding modules disposed on the machine base, each set of feeding modules including a feeding device and a transfer device; the feeding device being used to directionally convey the inductor housing or inductor coil to the transfer device; a mold conveying device disposed on the machine base, including an input belt conveyor, a first platform drive mechanism, and a second platform drive mechanism; the first platform drive mechanism including a platform conveyor rail, the platform conveyor rail being disposed at the discharge end of each set of feeding modules, being used to receive and convey the platform mold sequentially through each feeding module to receive materials; the input belt conveyor being disposed at the input end of the platform conveyor rail; the second platform drive mechanism being disposed at the discharge end of the platform conveyor rail, being used to output the platform mold.

[0009] The assembly equipment for the aforementioned TLVR inductor includes a feeding device comprising a vibratory feeder, a feeding rail connected to the vibratory feeder body, and a laser rangefinder sensor arranged along the conveying direction of the feeding rail, wherein the detection end of the laser rangefinder sensor is directly opposite the track of the feeding rail.

[0010] The aforementioned TLVR inductor assembly equipment includes a transfer device comprising a transfer drive mechanism and a transfer platform. The transfer platform has several receiving slots opening towards one side of the feeding rail. The transfer drive mechanism includes a transfer drive motor and a sliding support rail. The transfer drive motor and the transfer platform mounted on the sliding support rail form a screw drive structure to drive the transfer platform to move in a direction perpendicular to the feeding rail, so that each receiving slot is sequentially aligned with the outlet of the feeding rail.

[0011] The aforementioned TLVR inductor assembly equipment further includes a first transfer mechanism and a second transfer mechanism, which are connected end-to-end. Both the first and second transfer mechanisms are equipped with suction head modules at their drive ends. Each suction head module includes multiple negative pressure suction heads for transferring materials from the receiving tank to the platform mold.

[0012] The aforementioned TLVR inductor assembly equipment further includes a transfer device that is positioned between the first transfer mechanism and the second transfer mechanism. The transfer platform has a row of transfer grooves for temporarily storing materials picked up by the first transfer mechanism for the second transfer mechanism to pick up.

[0013] In the aforementioned TLVR inductor assembly equipment, a recycling frame is provided on both sides of the transition stage. The recycling frame is used to receive materials that the second transfer mechanism determines to be abnormally adsorbed.

[0014] The assembly equipment for the TLVR inductor described above further includes multiple sets of insertion and extraction components and a lead screw drive module in the first stage drive mechanism; the insertion and extraction components include insertion and extraction cylinders and insertion and extraction rods driven by the insertion and extraction cylinders, and the insertion and extraction rods are used to insert and cooperate with the drive holes on the stage mold to drive the stage mold to move.

[0015] The TLVR inductor assembly equipment described above has a pressing component at the discharge end of each of the feed modules. The pressing component includes a lower pressing fork and a lower pressing cylinder that drives the lower pressing fork to move vertically. The lower pressing fork is used to press the platform mold onto the platform conveyor rail.

[0016] The aforementioned TLVR inductor assembly equipment comprises a U-shaped layout of the feeding belt conveyor, the platform conveyor rail of the second platform drive mechanism, and the platform conveyor rail of the first platform drive mechanism. The number of feeding modules is four, arranged in parallel along the platform conveyor rail of the first platform drive mechanism. The TLVR inductor assembly equipment also includes a fifth feeding module, which is located within the area enclosed by the U-shaped layout, and its feeding direction is towards the platform conveyor rail of the second platform drive mechanism.

[0017] In the aforementioned TLVR inductor assembly equipment, the stage mold has multiple assembly slots, and the arrangement of the assembly slots matches the suction head layout of the suction head module in the transfer device.

[0018] The beneficial effects of this invention are: 1. Achieve full automation of the inductor assembly process. Through the coordinated work of multiple sets of feeding modules and mold conveying devices, it can continuously complete processes such as shell feeding, coil feeding, assembly and pressing, which greatly improves production efficiency and product consistency.

[0019] 2. The mold conveying path adopts a U-shaped layout, and the fifth feed module is set in the enclosed area of ​​the U-shaped layout. The whole machine has a compact structure and small footprint, and can meet the special assembly process requirements of first placing the outer shell and coil, and then repeating it once to ensure the stacked structure.

[0020] 3. The transfer device is equipped with a transition platform, a recycling frame, and an air pressure sensor, which can detect the adsorption status of each negative pressure suction head in real time, automatically remove materials with abnormal adsorption, and re-absorb them, ensuring the accuracy and reliability of material transfer and avoiding assembly defects caused by material shortage or skewing.

[0021] 4. By cooperating with the plug-in assembly and the clamping assembly, the platform mold can be accurately moved and positioned on the platform conveyor rail, ensuring that the mold position is stable during filling of each feed module and improving the accuracy of multi-station collaborative operation.

[0022] 5. The feeding device is equipped with a laser rangefinder sensor, which can automatically detect the orientation of the slotted surface of the material (shell) to ensure that the shell enters the subsequent process in the correct posture, thus avoiding assembly failure caused by incorrect material orientation from the source.

[0025] In the description of this invention, it should be understood that the terms center, longitudinal, transverse, length, width, thickness, front, back, left, right, upper, lower, axial, radial, vertical, horizontal, inner, and outer, indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Furthermore, the terms first and second are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as first or second may explicitly or implicitly include one or more of that feature. In the description of this invention, "multiple" means two or more, unless otherwise explicitly specified.

[0026] In this technical solution, the object to be assembled is an inductor. The inductor includes two identical housings and an inductor coil. Both housings are T-shaped, with the two housings being an upper housing and a lower housing. During assembly, the inductor coil needs to be pressed between the two housings. The upper and lower housings each have slots that match the structure of the inductor coil. During assembly, the inductor coil is first placed in the slot of one of the housings (as shown in the lower housing), and then the other housing (as shown in the upper housing) is snapped onto the previously placed housing, thus completing the assembly of the inductor. The snapping action is achieved by applying vertical pressure through an external pressing mechanism, ensuring a tight fit between the upper and lower housings.

[0027] An assembly device for a TLVR inductor, with reference to Figure 1 and 2 It includes a machine base 100, a feeding module and a mold conveying device 4.

[0028] In this embodiment, the machine 100 is provided with at least two sets of feeding modules, each set of feeding modules includes at least one feeding device 2 and a transfer device 3; the machine 100 is also provided with a mold conveying device 4.

[0029] In this embodiment, four sets of feeding device 2 and transfer device 3 are provided respectively. One feeding device 2 and one transfer device 3 form a feeding module, which respectively form a first feeding module 101, a second feeding module 102, a third feeding module 103 and a fourth feeding module 104.

[0030] Four sets of feed modules are arranged in parallel on the machine tool 100.

[0031] In this embodiment, the four sets of feeding modules are configured as follows: the first feeding module 101 is used to transport and place the lower housing of the inductor; the second feeding module 102 is arranged adjacent to the first feeding module 101 and is used to transport and place the inductor coil; the third feeding module 103 is arranged adjacent to the second feeding module 102 and is used to transport and place the lower housing of the inductor; the fourth feeding module 104 is arranged adjacent to the third feeding module 103 and is used to transport and place the inductor coil. Taking the above rule as an example, several sets of feeding modules can be set.

[0032] Reference Figure 9 The mold conveying device 4 is used to convey the platform mold 44, specifically including the feeding belt conveyor 41, the second platform drive mechanism 43 and the first platform drive mechanism 42.

[0033] Reference Figure 11 The first platform drive mechanism 42 includes a platform conveyor rail 421 and multiple lead screw drive modules.

[0034] The feeding belt conveyor 41 is located at the feed end of the platform conveyor rail 421, and the tail end of the feeding belt conveyor 41 is connected to the head end of the platform conveyor rail 421. The second platform drive mechanism 43 is located at the discharge end of the platform conveyor rail 421, and the head end of the second platform drive mechanism 43 is connected to the tail end of the platform conveyor rail 421.

[0035] Reference Figure 1 , Figure 2 and Figure 9 In this embodiment, the platform conveyor rail 421 is disposed at the discharge end of each group of feed modules. The platform conveyor rail 421 is arranged perpendicularly to the four groups of feed modules and passes through the discharge ends of the four groups of feed modules in sequence.

[0036] Reference Figure 9 In this embodiment, the feed belt conveyor 41, the second platform drive mechanism 43, and the platform conveyor rail 421 form a U-shaped layout. This U-shaped layout allows the platform mold 44 to enter from the feed belt conveyor 41, move along the platform conveyor rail 421, and be turned and output after being driven by the second platform drive mechanism 43, forming a continuous conveying path.

[0037] In this embodiment, a fifth feeding module 105 is also included. This fifth feeding module 105 is disposed within the area enclosed by a U-shaped layout formed by the feeding belt conveyor 41, the second platform drive mechanism 43, and the platform conveyor rail 421. The material conveying direction of the fifth feeding module 105 is perpendicular to the material conveying direction of the second platform drive mechanism 43, and the feeding direction of the fifth feeding module 105 is towards the second platform drive mechanism 43. The fifth feeding module 105 is used to convey and place the upper housing of the inductor, completing the final pressing assembly.

[0038] Reference Figure 3-8 The following example uses one of the feed modules: The feeding device 2 includes a feeding cylinder 21, which is mounted on the machine base 100. The feeding cylinder 21 is configured as a flared cylinder that is wider at the top and narrower at the bottom. The wide end of the feeding cylinder 21 faces upward and the narrow end faces downward. The wide end is provided with an opening for feeding material, and the narrow end is provided with an outlet for discharging material.

[0039] The feed cylinder 21 can be used with manual or automated feeding equipment to fill the lower housing of the inductor into the feed cylinder 21. The feeding device 2 also includes a vibratory feeder 24 and a feeding platform 22, both of which are mounted on the machine base 100. The feeding platform 22 has baffles 23 on both sides, which form a channel to constrain the movement of the lower housing. One end of the feeding platform 22 extends below the narrow end face of the feed cylinder 21 to receive the lower housing falling from the feed cylinder 21; the other end of the feeding platform 22 is mounted on the disc of the vibratory feeder 24 to move the lower housing on the feeding platform 22 towards the disc of the vibratory feeder 24. Because the feeding platform 22 is in contact with the vibratory feeder 24, the vibratory feeder 24 can drive the feeding platform 22 to vibrate together when it vibrates. The feeding platform 22 is slightly inclined towards the vibratory feeder 24, allowing the material to be gradually moved under the action of vibration. The lower housing of the inductor is discharged through the narrow end of the feed cylinder 21 and falls onto the feed table 22. It is then moved by the continuously vibrating feed table 22 into the disc of the vibrating plate 24. The vibrating plate 24 is equipped with a spiral track and a direction selection structure, which allows the lower housing to automatically adjust its posture during movement to ensure that the slotted surface faces upward.

[0040] The feeding device 2 also includes a feeding rail 25 connected to the vibratory plate 24. The feeding rail 25 allows only the lower outer shell to pass through at a time, and a vibratory motor 253 is provided below the feeding rail 25.

[0041] Along the conveying direction of the feeding rail 25, a laser rangefinder 251 and a through-beam sensor 252 are sequentially arranged. The laser rangefinder 251 is fixedly mounted on the side of the feeding rail 25 by a mounting plate, and is positioned directly above the track of the feeding rail 25, so that the detection end of the laser rangefinder 251 faces the track of the upper rail. The lower housing passing through the track of the feeding rail 25 will sequentially pass through the bottom detection area of ​​the laser rangefinder 251. Since one side of the lower housing and the upper housing is slotted and the other side is flat, the value detected by the laser rangefinder 251 will be different when the slotted side of the lower housing or the upper housing faces upward and when the non-slotted side faces upward. In particular, when the object conveyed in the feeding rail 25 is an inductor coil, the laser rangefinder 251 may not be provided, or the function of the laser rangefinder 251 may be changed to whether material is passing through this area.

[0042] In this embodiment, the slotted surface of the lower housing is allowed to face upwards, i.e., the slotted surface of the lower housing faces the laser rangefinder 251. Only when the lower housing passes through in this state can the data detected by the laser rangefinder 251 be judged as qualified by the system. The function of the vibratory feeder 24 is to make the slotted end of the lower housing face the upper feed rail 25 and enter the upper feed rail 25.

[0043] If the slotted end of the lower casing faces downwards, the system will issue an alarm.

[0044] In this embodiment, the method for removing the substandard lower casing can be manual removal. That is, when the laser rangefinder 251 detects the corresponding lower casing, the vibration motor 253 stops, and the lower casing remains at the location of the laser rangefinder 251, where it is manually removed. After manual removal, the vibration motor 253 can be restarted manually or through the control system to continue the detection and conveying of subsequent materials.

[0045] A through-beam sensor 252 is installed on the discharge direction of the feeding rail 25, that is, on the side of the feeding rail 25 away from the vibratory feeder 24. This through-beam sensor 252 is used to detect and count the passing of the lower housing. The count value can be used to monitor the continuity of material conveying and to count the output.

[0046] The transfer device 3 is located on the side of the feeding rail 25 away from the vibratory feeder 24. The transfer device 3 includes a transfer drive mechanism 31 and a transfer platform 32. The transfer platform 32 has several receiving slots 321. The receiving slots 321 open to the side of the transfer platform 32 and are located on the side of the transfer platform 32 facing the feeding rail 25.

[0047] In this embodiment, six receiving slots 321 are provided, and each receiving slot 321 is opened on one side facing the feeding rail 25.

[0048] The transfer drive mechanism 31 includes a transfer drive motor 311 and a sliding bearing rail 313 fixed on the machine base 100. The length direction of the transfer drive motor 311 and the sliding bearing rail 313 is perpendicular to the length direction of the feeding rail 25, and the driving direction of the transfer drive motor 311 is perpendicular to the direction of the feeding rail 25 transporting the housing.

[0049] A sliding bearing threaded block 312 is provided on the sliding bearing rail 313, and the sliding bearing threaded block 312 is slidably mounted on the sliding bearing rail 313. The transfer table 32 is fixedly mounted on the sliding bearing threaded block 312. The output shaft of the transfer drive motor 311 and the sliding bearing threaded block 312 form a screw drive structure, which is used to drive the sliding bearing threaded block 312 to move along the direction of the sliding bearing rail 313.

[0050] The drive stroke of the transfer drive motor 311 on the transfer table 32 is controlled by the equipment control system. The distance of a single movement is the distance between two adjacent receiving slots 321, the purpose of which is to ensure that each receiving slot 321 can be aligned with the outlet of the feeding rail 25. Specifically, the transfer drive mechanism 31 also includes a conventional magnetic sensor 314. The magnetic sensor 314 realizes the equidistant movement of the sliding bearing threaded block 312 based on the principle of non-contact magnetic field induction. It includes a sensing element 315 and a magnetically conductive metal 316. The sensing element 315 is fixedly installed on one side of the sliding bearing rail 313, and the magnetically conductive metal 316 is fixedly installed on the sliding bearing threaded block 312.

[0051] In addition, at the end of the sliding bearing rail 313, that is, near the discharge position of the feeding rail 25, an end positioning sensor 317 is fixedly installed. The end positioning sensor 317 is set as an infrared sensing sensor.

[0052] When the transfer drive motor 311 drives the transfer table 32 to move, it aligns the receiving slot 321 on the transfer table 32 with the outlet of the feeding rail 25. The end positioning sensor 317 detects whether the receiving slot 321 has reached the predetermined position, that is, whether the receiving slot 321 is aligned with the outlet of the feeding rail 25. If the receiving slot 321 is aligned, a signal is sent to the control system, and the transfer drive motor 311 stops running.

[0053] The magnetic sensor 314 is used to detect whether the sliding bearing threaded block 312 is moving towards or away from the transfer drive motor 311, and its function is to provide a memory signal. Since the transfer drive motor 311 needs to stop when the receiving groove 321 is aligned with the outlet of the feeding rail 25, the transfer drive motor 311 needs to be started and stopped frequently during this process. The magnetic sensor 314 can provide a signal memory point for whether the sliding bearing threaded block 312 is approaching or moving away, so that the transfer drive motor 311 can determine the next direction of movement when it starts again.

[0054] With the cooperation of the magnetic sensor 314 and the end positioning sensor 317, the turntable 32 can achieve precise stepping movement and position feedback.

[0055] The transfer device 3 also includes two sets of identical transfer mechanisms, namely a first transfer mechanism 33 and a second transfer mechanism 34. Taking one of the transfer mechanisms as an example, the first transfer mechanism 33 is configured as a biaxial linear module, specifically including an X-axis and a Z-axis. The drive end of the first transfer mechanism 33 drives a suction head module 331, which includes multiple negative pressure suction heads 332. In this embodiment, six negative pressure suction heads 332 are provided, each corresponding to one of the six receiving slots 321. Each negative pressure suction head 332 is connected to an external negative pressure system through a pipeline, and each pipeline is equipped with a pressure sensor to detect the air pressure inside the pipeline after each negative pressure suction head 332 picks up a workpiece. The pressure sensor can monitor the adsorption status of each suction head in real time. If a suction head fails to pick up a workpiece or adsorbs too tightly, the air pressure value will deviate from the set range.

[0056] The second transfer mechanism 34 is connected end-to-end with the first transfer mechanism 33 and is used to continue to transfer the lower outer shell transferred by the first transfer mechanism 33 along the transfer direction of the first transfer mechanism 33.

[0057] The transfer mechanism also includes a transition platform 35, which is adjacent to the transfer platform 32. The transition platform 35 has at least one row of transition grooves 351, which are identical in shape and size to the receiving grooves 321. One row of transition grooves 351 includes six transition grooves. On both sides of the transition platform 35, i.e., along the transport direction of the first transfer mechanism 33 or the second transfer mechanism 34, a collection frame 352 is provided. The collection frame 352 is used to temporarily store workpieces determined to have adsorption abnormalities, which can then be cleaned manually or automatically.

[0058] The specific structure of the mold conveying device 4, which works in conjunction with the feed module, is as follows.

[0059] The platform mold 44 has multiple assembly slots 442. In this embodiment, the assembly slots 442 are arranged in rows of six to facilitate cooperation with the suction head module 331, and multiple rows of assembly slots 442 are arranged in parallel. The platform mold 44 also has a drive hole 441, which is used to cooperate with the first platform drive mechanism 42 to drive the platform mold 44.

[0060] The conveying direction of the platform conveyor rail 421 is perpendicular to the conveying direction of the second transfer mechanism 34. In this embodiment, there is one platform conveyor rail 421, and a single platform conveyor rail 421 passes through the material conveying end of the four sets of transfer devices 3, that is, the side of the second transfer mechanism 34 away from the first transfer mechanism 33.

[0061] Reference Figure 10 and Figure 11Specifically, the first platform drive mechanism 42 includes a platform conveyor rail 421, multiple lead screw drive modules, and multiple sets of insertion and extraction assemblies 45. In this embodiment, there are two sets of lead screw drive modules: a first lead screw drive module 425 and a second lead screw drive module 426. The first lead screw drive module 425 and the second lead screw drive module 426 are connected end-to-end and form a straight line. There are four sets of insertion and extraction assemblies 45, of which two sets are driven by the first lead screw drive module 425, and the other two sets are driven by the second lead screw drive module 426.

[0062] Specifically, the insertion / removal assembly 45 includes a mounting platform 451, which is mounted on the drive end face of the lead screw drive module. The insertion / removal assembly 45 also includes a connecting plate 452 and two vertical fixing platforms 453, each vertically mounted at one end of the connecting plate 452. The connecting plate 452 is fixedly mounted on the mounting platform 451. The insertion / removal assembly 45 also includes an insertion / removal cylinder 454 and insertion / removal rods 455. The insertion / removal cylinder 454 is fixedly mounted on each vertical fixing platform 453, and its driving direction is perpendicular to the machine base 100. The insertion / removal rods 455 are mounted on the output shaft of the insertion / removal cylinder 454. Each insertion / removal cylinder 454 drives two insertion / removal rods 455. The dimensions of the insertion / removal rods 455 match those of the drive holes 441, allowing the insertion / removal rods 455 to be inserted into or removed from the drive holes 441 as driven by the insertion / removal cylinder 454. Therefore, a set of plug-in components 45 can transport two platform molds 44 at the same time.

[0063] Two sets of lead screw drive modules are used to transport four platform molds 44. The four platform molds 44 correspond one-to-one with four sets of transfer devices 3, forming a multi-station transportation layout. Each station corresponds to a feeding module, and the platform molds 44 move stepwise between stations to receive different materials in sequence.

[0064] In addition, a clamping assembly 422 is provided at the feeding end of each set of transfer devices 3. The clamping assembly 422 includes a lower clamping fork 423 and a lower clamping cylinder 424. The four sets of clamping assemblies 422 are respectively arranged on the discharge side of the transfer device 3 near the four sets of feeding modules on the platform conveyor rail 421, and the four clamping assemblies 422 are respectively arranged on the discharge end of the second transfer mechanism 34. The clamping cylinder drives the lower clamping fork 423 to move vertically. When the platform mold 44 is moved to the corresponding station by the insertion and extraction assembly 45, the clamping assembly 422 presses down, pressing the platform mold 44 tightly on the platform conveyor rail 421 to prevent it from shifting during the filling process.

[0065] In this embodiment, the feeding belt conveyor 41 is set as a conventional belt conveyor mechanism, and the structure of the second platform drive mechanism 43 is the same as that of the first platform drive mechanism 42, both including a platform conveyor rail 421, a lead screw drive module and a plug-in assembly 45.

[0066] The two are arranged in different positions in the equipment and are responsible for different conveying stages: the first platform drive mechanism 42 is located at the front of the equipment, and its platform conveying rail 421 is arranged along the discharge end of the first to fourth feed modules 104, which is used to move the platform mold 44 from the feeding end through the first to fourth feed modules 104 in sequence. The second platform drive mechanism 43 is located at the rear of the equipment. Its platform conveying rail 421 is vertically connected to the platform conveying rail 421 of the first platform drive mechanism 42. It is used to continue to move the platform mold 44 through the fifth feed module 105 and finally output it.

[0067] The discharge end of the transfer device 3 of the fifth feed module 105 is also provided with a pressing component 422. The pressing component 422 is located between the platform conveying rail 421 included in the second platform drive mechanism 43 and the second transfer mechanism 34 included in the fifth feed module 105.

[0068] The feeding end of the platform conveying rail 421 included in the second platform drive mechanism 43 is connected to the discharging end of the platform conveying rail 421 of the first platform drive mechanism 42, and the two are connected perpendicularly.

[0069] A platform mold 44 is transported from the conveyor belt 41 to the platform conveyor rail 421, with the end of the conveyor belt 41 corresponding to the first clamping assembly 422 arranged in the straight direction of the platform conveyor rail 421. When the platform mold 44 is transported to the platform conveyor rail 421, it first enters the range of the clamping assembly 422. The pressing cylinder 424 drives the pressing fork 423 to press down, clamping and fixing the arriving platform mold 44 to facilitate subsequent filling of the platform mold 44.

[0070] The insertion cylinder 454 drives the insertion rod 455 to insert into the platform mold 44. Then, the first lead screw drive module 425 is activated, moving the insertion assembly 45 along the length of the platform conveyor rail 421, thus moving the platform mold 44 to the discharge end of the second set of feed modules. The second lead screw drive module 426 operates in the same manner: the insertion cylinder 454 drives the insertion rod 455 to insert into the platform mold 44, and then the second lead screw drive module 426 is activated, moving the insertion assembly 45 along the length of the platform conveyor rail 421 until the platform mold 44 passes the discharge ends of the first to fourth feed modules 104 in sequence. Each lead screw drive module moves according to a set step distance, ensuring that the platform mold 44 precisely stops at the corresponding filling position of each feed module.

[0071] Subsequently, the first platform drive mechanism 42 transfers the platform mold 44 to the second platform drive mechanism 43. The second platform drive mechanism 43 moves the platform mold 44, causing it to pass through the fifth feed module 105. Finally, the second platform drive mechanism 43 conveys the platform out and passes through a vision sensor 1. After being detected by the vision sensor 1, the second platform drive mechanism 43 conveys the assembled platform mold 44 to the equipment outlet for the next hot pressing process.

[0072] The implementation principle of the embodiments in this application is as follows: The five feeding modules in this device operate in the same way, differing only in the object they feed. In this embodiment, the first feeding module 101 feeds the lower outer shell; the second feeding module 102 feeds the inductor coil; the third feeding module 103 feeds the lower outer shell; the fourth feeding module 104 feeds the inductor coil; and the fifth feeding module 105 feeds the upper outer shell. In the above process, the first feeding module 101 places a lower outer shell, and the second feeding module 102 installs the inductor coil into the lower outer shell; the third feeding module 103 and the fourth feeding module 104 repeat the process of the first feeding module 101 and the second feeding module 102; subsequently, the stage mold 44 is moved by the second stage drive mechanism 43 to the fifth feeding module 105 to complete the feeding of the upper outer shell. The feeding of the upper outer shell refers to pressing the upper outer shell onto the inductor coil, thereby completing the overall assembly of the upper outer shell, the inductor coil, and the lower outer shell.

[0073] The following section uses the first feed module 101 as an example to explain in detail the feeding and transfer process of a single module: The lower outer casing is placed in the feed cylinder 21 beforehand, then falls down along the feed cylinder 21 and onto the feed platform 22. The feed platform 22 vibrates, moving the lower outer casing into the vibratory feeder 24. The vibratory feeder 24 places the lower outer casing with its mounting surface facing upwards and moves it to the upper feed rail 25. The upper feed rail 25 transports the lower outer casing toward the transfer device 3 by vibration and tilting.

[0074] The transfer drive mechanism 31 drives the transfer table 32 to move in a direction perpendicular to the feeding direction of the feeding rail 25, so that each receiving slot 321 on the transfer table 32 is aligned with the discharge position of the feeding rail 25. After each lower shell has fallen into the slot of the transfer table 32, that is, after all six receiving slots 321 are full of lower shells, the first transfer mechanism 33 is activated.

[0075] The drive suction head module 331 of the first transfer mechanism 33 or the second transfer mechanism 34 inserts each negative pressure suction head 332 into the receiving slot 321 on the transfer table 32, and then removes the lower outer shell from it. In this embodiment, the negative pressure suction head 332 values ​​detected by each air pressure sensor should be within the same value range, that is, the values ​​of the six air pressure sensors should not differ too much. This value range is preset by the operator in the control system. If the value difference is too large, it indicates that some lower outer shells are suctioned too tightly and some are suctioned too loosely, resulting in uneven or inaccurate placement of the lower outer shells.

[0076] Subsequently, the first transfer mechanism 33 moves the six lower housings picked up from the receiving slot 321 of the transfer platform 32 to the transition slot 351 of the transition platform 35. The transition platform 35 serves as a buffer and attitude adjustment mechanism to ensure that the second transfer mechanism 34 can stably pick them up.

[0077] The second transfer mechanism 34 begins to pick up the upper outer shells from the transition platform 35, adsorbing six upper outer shells at a time. If the values ​​detected by the six pressure sensors differ significantly, it indicates that some lower outer shells are being adsorbed too tightly. In this case, the second transfer mechanism 34 needs to place these lower outer shells in the recovery frame 352 and then pick up six new lower outer shells from the transition platform 35. The second transfer mechanism 34 then moves the lower outer shells to the platform mold 44 in its discharge direction, filling each assembly slot 442 on the platform mold 44 with lower outer shells. The re-picking process can be automatically repeated until the pressure values ​​of all six suction heads are within the acceptable range.

[0078] In the above order, the second feed module 102, the third feed module 103 and the fourth feed module 104 respectively feed materials.

[0079] The first stage drive mechanism 42 moves the stage mold 44, which has completed the above process, to the second stage drive mechanism 43. Upon reaching the second stage drive mechanism 43, each assembly slot 442 contains a lower outer casing and an inductor coil.

[0080] The fifth feed module 105 feeds the upper housing, placing and pressing it onto the inductor coil according to the above process, thus completing the assembly of the inductor coil. Subsequently, the second stage drive mechanism 43 transports the assembled inductor toward the equipment's output direction for the next hot pressing process. The hot pressing process can be carried out in a separate hot press or completed by a hot pressing station integrated into the equipment.

[0081] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
