Description

Technical Field

[0001] This utility model relates to the field of surface mount inductor manufacturing technology, and in particular to an inductor coil assembly molding equipment. Background Technology

[0002] In the field of electronic component manufacturing, inductor coil assemblies, as key semi-finished products of core components such as surface mount inductors and power inductors, require multiple processes in their forming and processing, including material supply, assembly and soldering, wire cutting, and finished product placement. With the continuous growth in demand for inductor components from downstream industries such as consumer electronics and new energy, and the rapid iteration of products towards miniaturization and high precision, existing inductor coil assembly forming lines can no longer meet the needs of large-scale, high-stability production.

[0003] Currently, inductor coil assembly molding generally relies on a decentralized equipment combination: lead sheet supply, inductor coil supply, inductor coil assembly soldering, and post-processing cutting are all handled by independent equipment, each focusing on a single function. In this model, the lack of unified process coordination standards between these decentralized devices leads to a mismatch between the material delivery rhythms of the lead sheet and inductor coil supply equipment and the operating rhythm of the soldering equipment. This inevitably results in frequent downtime for the soldering equipment due to material shortages or material accumulation, directly disrupting production continuity.

[0004] In addition, after welding, the inductor coil assembly needs to be transferred to a separate cutting device via an additional transfer device for processing excessively long wires; the cut finished product then needs to be stored using another set of housing equipment. The transfer connections between multiple devices have significant time and spatial gaps, which not only significantly increases the risk of damage to the inductor coil assembly during transfer but also creates breakpoints due to the independent operation of each stage, leading to an extended overall production cycle.

[0005] The aforementioned modular equipment combination is essentially a simple stacking of functional modules, failing to form an overall operational system centered around the inductor coil assembly. It cannot achieve closed-loop control of the entire process from material input to finished product output, and has become a core bottleneck restricting the improvement of inductor coil assembly production efficiency and product quality.

Detailed Implementation

[0037] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , Figure 2 Two perspective views of the inductor coil assembly forming equipment disclosed in this utility model are shown. It can be seen that it is mainly composed of a machine base 1, a lead wire board feeding machine 2, an inductor coil feeding machine (not shown in the figure), an inductor coil assembly carrying machine 3, an inductor coil assembly post-processing assembly equipment 4, and a resistance spot welding machine 5. The machine base 1 serves as the core foundation for equipment installation. The lead wire board feeding machine 2, the inductor coil assembly carrying machine 3, the inductor coil assembly post-processing assembly equipment 4, and the resistance spot welding machine 5 all use it as their installation reference and are arranged collaboratively along the production process of the inductor coil assembly. The inductor coil assembly carrying machine 3 is used to sequentially receive multiple inductor coils and lead wire boards, and is sequentially equipped with an inductor coil loading station, a lead wire board loading station, a spot welding station, and an inductor coil assembly unloading station (e.g., ...). Figure 8 , Figure 9(As shown in the diagram); the lead sheet supply machine 2 is used to support the stacked lead sheets and accurately transport a single lead sheet to the lead sheet loading station; the inductor coil supply machine is used to transport multiple inductor coils sequentially to the inductor coil loading station, so that the inductor coils and lead sheets form a welding assembly on the positioning fixture; the resistance spot welding machine 5 is set up corresponding to the spot welding station and is specifically used to perform spot welding operations on the welding assembly at the spot welding station; the inductor coil assembly post-processing assembly equipment 4 is used to receive the inductor coil assembly output from the inductor coil assembly unloading station, cut the excessively long wires on the assembly, and transfer the cut finished product to the preset location for placement.

[0038] To further optimize the efficiency and stability of leadboard supply, and to meet the requirements for efficient separation and precise delivery of stacked leadboards: such as Figures 3-5 As shown, the wire board supply machine 2 mainly consists of several parts, including a wire board temporary storage fixture group 21, a sliding drive module 22, a lifting unit 23, an airflow generating unit 24, a stripping unit 25, and a wire board picking device 26. Among them, the wire board temporary storage fixture group 21 serves as the core of material storage and is used to support stacked wire boards. The wire board temporary storage fixture group 21 includes a left wire board temporary storage fixture 211 and a right wire board temporary storage fixture 212, which are arranged at intervals along the driving direction (i.e., laterally) of the sliding drive module 22. The sliding drive module 22 is used to drive either the left wire board temporary storage fixture 211 or the right wire board temporary storage fixture 212 to move to the preset feeding area. When the wire boards in one of the temporary storage fixtures (left wire board temporary storage fixture 211 or right wire board temporary storage fixture 212) are about to be exhausted, it quickly switches to the other fully loaded temporary storage fixture, thereby achieving the design purpose of continuous replenishment of wire boards.

[0039] The core function of the lifting unit 23 is to dynamically adjust the stacking height of the guide plates through lifting and lowering movements. For example... Figure 6 As shown, the lifting unit 23 includes a linear drive element 231, a lifting rod assembly 232, and a lifting plate 233. The linear drive element 231 drives the lifting rod assembly 232 to lift the lifting plate 233, so that the stacked lead plates are sequentially adapted to the preset picking height of the lead plate picking device 26 from the top layer, meeting the requirements for stable picking. After the lead plate picking device 26 completes a single picking, the lifting unit 23 will enter a transient unloading state, that is, the linear drive element 231 drives the lifting rod assembly 232 to lift the lifting plate 233 to retract downwards at a speed of 50-150 mm / s, and the retraction displacement is not less than the thickness of a single lead plate, so that the remaining stacked lead plates are temporarily in a weightless state, breaking the tight adhesion balance formed between the plates due to the stacking pressure and surface adsorption force, creating the basic conditions for subsequent adhesion separation.

[0040] Similarly, Figures 3-5As shown, the airflow generating unit 24 includes a support frame 241 and multiple air supply pipes 242. Each air supply pipe 242 has blowing holes arranged in an array along its length and is symmetrically arranged on both sides of the left lead plate temporary storage fixture 211 and / or the right lead plate temporary storage fixture 212. After the lifting unit 23 completes the transient unloading, the airflow generating unit 24 blows gas to the remaining stacked lead plates through the blowing holes of the air supply pipes 242, forming a small gap between adjacent lead plates and further weakening the inter-plate adhesion.

[0041] like Figure 7 As shown, the stripping unit 25 includes a mounting base 251 and a stripping functional component 252 with a through-slit 2521, the width of which is adapted to the thickness of a single conductor board. The conductor board picking device 26 is used to pick up the conductor board and transport it to the conductor board loading station. During the transport process, the conductor board must pass through the through-slit 2521. If multiple conductor boards are stuck together, the through-slit 2521 will block the excess conductor board, forcibly separating it from the picked single conductor board, ensuring that the conductor board finally delivered to the conductor board loading station is a single piece, thus ensuring the accuracy of the subsequent assembly of the inductor coil and the conductor board.

[0042] Through the functional synergy of the above components, the lead plate supply machine 2 achieves fully automated operation from lead plate storage, dynamic replenishment, height adjustment, anti-sticking pretreatment to precise single-piece delivery, effectively improving the efficiency and stability of lead plate supply, and better adapting to the continuous production needs of inductor coil assembly molding equipment.

[0043] The inductor coil assembly, which carries the mechanical component 3, is the core component for realizing the flow of movement between workstations. Its structural design must meet the dual requirements of intermittent circumferential rotation and translational adjustment. For example... Figures 8-10 As shown, the inductor coil assembly carrying mechanism 3 mainly consists of a material tray 31, a positioning fixture 32, an intermittent indexing drive unit 33, and a translation drive unit 34. The material tray 31 has four mounting positions spaced circumferentially. Each mounting position is fixedly equipped with a positioning fixture 32, and the four positioning fixtures 32 correspond one-to-one with the inductor coil loading station, the conductor plate loading station, the spot welding station, and the inductor coil assembly unloading station. The positioning fixture 32 is also equipped with a coil positioning groove 321 adapted to the shape of the inductor coil and a plate positioning groove 322 adapted to the shape of the conductor plate (e.g., ...). Figure 11As shown in the diagram, to ensure accurate placement and alignment of the inductor coil and the conductor plate; the intermittent indexing drive unit 33 includes a motor 331 and a cam indexer 332. The output shaft of the motor 331 is drivenly connected to the input shaft of the cam indexer 332, and the output end of the cam indexer 332 is drivenly connected to the material tray 31 to drive the material tray 31 to achieve intermittent circumferential rotation, thereby ensuring the orderly connection of operations at each station; the translation drive unit 34 includes a linear motor module 341, a slide rail slider assembly 342, and a platform 343. The mover of the linear motor module 341 is fixedly connected to the platform 343, and the platform 343 achieves directional sliding through the slide rail slider assembly 342. The motor 331 uses the platform 343 as the mounting base and can drive the intermittent indexing drive unit 33 and the material tray 31 to translate as a whole, ensuring accurate alignment of the assembly to be welded with the resistance spot welding machine 5.

[0044] The inductor coil assembly post-processing assembly equipment 4 is responsible for cutting and accommodating the post-soldering assemblies. Its structural design needs to be adapted to the efficient transfer and continuous storage of the assemblies. For example... Figure 12 , Figure 13 As shown, the inductor coil assembly post-processing assembly equipment 4 mainly consists of several parts, including a material feeding and conveying machine 41, a cutting machine 42, and a housing unit 43. Among them, as... Figure 14 As shown, the unloading and transfer mechanism 41 has a degree of freedom of movement along a preset trajectory. It includes a lateral drive unit 411 (preferably a linear motor module), a first picking robotic arm 412, and a second picking robotic arm 413. Both the first picking robotic arm 412 and the second picking robotic arm 413 have lifting functions and are both connected to the lateral drive unit 411. The first picking robotic arm 412 is used to pick up the welded components and transfer them to the working area of ​​the cutting machine 42, while the second picking robotic arm 413 is used to pick up the cut inductor coil components and transfer them to the receiving unit 43. The cutting machine 42 is arranged to correspond to the movement trajectory of the unloading and transfer mechanism 41. Its cutting end is precisely matched with the position of the excessively long wire to be cut on the component to realize the automated cutting of the excessively long wire on the inductor coil component. The receiving unit 43 is located at the end of the movement trajectory of the unloading and transfer mechanism 41 and is composed of a first receiving fixture 431 and a second receiving fixture 432. The first receiving fixture 431 and the second receiving fixture 432 are arranged sequentially along a preset trajectory to alternately receive finished components, thereby avoiding production interruptions caused by unloading.

[0045] The structural design of the resistance spot welding machine 5 must ensure spot welding accuracy and operational stability. For example... Figure 15 , Figure 16As shown, the resistance spot welding machine 5 mainly consists of a frame 51, an upper welding arm 52, a lower welding arm 53, and a feed-in drive unit 54. Both the upper welding arm 52 and the lower welding arm 53 are loaded by the frame 51 and move in opposite directions to apply clamping pressure to the assembly to be welded, or move in opposite directions to release the welded components. The feed-in drive unit 54 is driven by the frame 51 and includes a linear motor module 541, a longitudinal slide rail slider assembly 542, and a longitudinal sliding stage 543. The linear motor module 541 is driven by the longitudinal sliding stage 543, which carries the frame 51 and achieves directional sliding through the longitudinal slide rail slider assembly 542 to drive the frame 51 to perform stepping motion. The step distance is adapted to the spacing between two welding points on a single inductor coil, ensuring accurate welding point positioning.

[0046] It should also be noted that the resistance spot welding machine 5 is further equipped with a lateral fine-tuning unit 55 and a lateral slide rail slider assembly 56. The lateral fine-tuning unit 55 is mounted on the longitudinal sliding stage 543 and is used to adjust the lateral relative position of the frame 51. The lateral slide rail slider assembly 56 is assembled between the frame 51 and the longitudinal sliding stage 543, which helps to further improve the position adjustment accuracy of the resistance spot welding machine 5.

[0047] From the perspective of overall equipment layout and functional integration, this utility model integrates material supply (including inductor coil supply and conductor board supply), workstation support, spot welding and forming, and post-processing cutting into the same equipment system. All components are arranged collaboratively around the unified benchmark and production process of machine 1, eliminating the need for separate installation foundations and material channels for individual functional modules. This significantly reduces the overall footprint of the equipment and lowers the complexity of installation, commissioning, and subsequent maintenance. Furthermore, the fully automated collaborative operation eliminates manual intervention and waiting gaps between processes. This not only improves the production efficiency of inductor coil components but also ensures consistent finished product quality through precise workstation docking and equipment positioning, effectively reducing the risk of damage to components during transport and significantly lowering the defect rate of inductor coil components.

[0048] Based on the aforementioned inductor coil assembly molding equipment, the inductor coil assembly molding method specifically includes the following steps: S1. Equipment initialization and material preparation: Place the stacked leadboards into the left leadboard temporary storage fixture 211 and the right leadboard temporary storage fixture 212, and load multiple inductor coils into the hopper of the inductor coil supply machine; start the sliding drive module 22 to drive the left leadboard temporary storage fixture 211 or the right leadboard temporary storage fixture 212 to move to the preset loading area. Then, the linear drive element 231 drives the lifting rod assembly 232 to lift the lifting plate 233 so that the top of the stacked leadboards matches the height position of the stripping function 252. At the same time, adjust the multi-degree-of-freedom robot of the inductor coil supply machine to the initial picking position. S2. Inductor coil supply and positioning: The multi-degree-of-freedom robot arm of the inductor coil supply machine picks up multiple inductor coils from the hopper in sequence and moves them one by one along the preset trajectory to the inductor coil loading station. Each inductor coil is placed in the coil positioning slot 321 until all the inductor coils are placed in the coil positioning slot 321 of the positioning fixture 32 at the station. S3. Formation of lead plate supply and assembly for soldering: After all the inductors at the inductor coil loading station have been placed, the lead plate supply machine 2 starts the lead plate supply process: First, the airflow generating unit 24 blows gas into the stacked lead plates in the lead plate temporary storage fixture 21 through the air supply pipe 242 arrayed along the length direction of the airflow holes. The airflow forms a small gap between adjacent lead plates, preventing the stacked lead plates from sticking together due to pressure or static electricity from the source. Then, the lead plate picking device 26 picks up the lead plate and moves it to the lead plate loading station. During the transfer process, the lead plate needs to pass through the through-slit 2521 opened by the stripping function 252. Because the width of the through-slit 2521 is adapted to the thickness of a single conductor board, if multiple conductor boards are stuck together, the through-slit 2521 will block the excess conductor boards, forcing them to separate into single pieces, ensuring that the conductor board finally delivered to the positioning fixture 32 at the conductor board loading station is a single piece; after the single conductor board enters the positioning fixture 32, it precisely corresponds and fits with multiple pre-placed inductor coils to form a welding assembly; at the same time, after the lifting plate 233 completes a single conductor board pickup, the displacement of the downward retraction of the single lifting plate 233 is not less than the thickness of a single conductor board, adjusting the stacking height for the next conductor board supply to ensure the continuity and stability of subsequent conductor board supply; S4. Workstation Flow and Spot Welding: The intermittent indexing drive unit 33 is started, and the motor 331 drives the cam indexer 332 to drive the material tray 31 to perform intermittent circumferential rotation so that the positioning fixture 32 with the assembly to be welded is transferred to the spot welding station; the linear motor module 341 drives the platform 343 to perform lateral sliding motion to adjust the relative position of the material tray 31, thereby ensuring that the assembly to be welded is aligned with the upper welding arm 52 and the lower welding arm 53; the feed-in drive unit 54 drives the frame 51 to perform stepping movement along the longitudinal direction, and the step distance is adapted to the distance between the two welding points on a single inductor coil.
