Description

Technical Field

[0001] This invention relates to the field of automated equipment for electromagnetic component processing, and in particular to an electromagnetic component fixture and a multi-station rotary loading device. Background Technology

[0002] In the automated assembly of electromagnetic components such as inductors and transformers, the core processes include fitting the magnetic core to the insulating frame, attaching the coil leads, and subsequent wire management.

[0003] Most assembly equipment in related technologies adopts a linear flow layout. Because different assembly steps have varying angular constraints on the coil leads (wire beginnings and ends), the linear flow pattern typically requires specialized fixtures with different structures at each processing station. In actual operation, a robotic arm must be used to remove the electromagnetic components from the fixture at the previous station, then transfer, adjust their orientation, and reposition them into the specific fixture at the next station. This frequent transfer process not only significantly extends the non-processing cycle time, leading to low production efficiency, but also easily generates secondary positioning errors due to the reciprocating movement of components between multiple non-standard fixtures, affecting the precision of the mounting feet.

[0004] More importantly, traditional fixtures often only provide static constraints in a single orientation. When the process requires the coil to rotate relative to the magnetic core (e.g., the coil is forced to rotate when the wire end is pulled), existing fixtures usually cannot dynamically adapt to the different physical positions of the wire end before and after rotation while maintaining stable clamping of the magnetic core. This technical limitation makes the entire process more complex and inefficient. Summary of the Invention

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide an electromagnetic component fixture and a multi-station rotary loading device for electromagnetic components.

[0006] To achieve the above objectives, in one aspect, an electromagnetic element fixture according to an embodiment of the present invention includes:

[0007] A fixture base for supporting an electromagnetic component, the fixture base being configured to open and close for selectively clamping or releasing the magnetic core of the electromagnetic component;

[0008] A skeleton clamping mechanism is located on the side of the fixture seat and is used to clamp and limit the insulating skeleton during the assembly of the insulating skeleton and the electromagnetic component.

[0009] A wire clamping mechanism is used to clamp the wire ends of the coil on the electromagnetic element.

[0010] The first wire tail clamping mechanism and the second wire tail clamping mechanism are distributed at intervals along the periphery of the fixture seat;

[0011] The spatial distribution between the first wire tail clamping mechanism and the second wire tail clamping mechanism is adapted to the wire tail extension direction of the coil before and after rotation and displacement on the fixture seat, so that one of the first wire tail clamping mechanism and the second wire tail clamping mechanism can clamp the wire tail before rotation and displacement of the coil, and the other of the first wire tail clamping mechanism and the second wire tail clamping mechanism can clamp the wire tail after rotation and displacement of the coil.

[0012] In addition, the electromagnetic component fixture according to the above embodiments of the present invention may also have the following additional technical features:

[0013] According to one embodiment of the present invention, the first wire tail clamping mechanism and the second wire tail clamping mechanism are respectively disposed on opposite sides of the fixture seat in a first direction;

[0014] The wire end clamping mechanism is disposed between the first wire end clamping mechanism and the fixture seat, or between the second wire end clamping mechanism and the fixture seat, so that the first wire end clamping mechanism, the wire end clamping mechanism, the fixture seat, and the second wire end clamping mechanism are arranged in a straight line in space.

[0015] The skeleton clamping mechanism is located on both sides of the fixture seat in the second direction, and the first direction is perpendicular to the second direction.

[0016] According to one embodiment of the present invention, the fixture base includes:

[0017] The fixed base is provided with an open slot;

[0018] A clamping seat is provided opposite to the fixed seat and is movably configured on the open side of the open slot so as to open or close the open slot, thereby releasing or clamping the magnetic core of the electromagnetic element placed in the open slot;

[0019] A first elastic element acts on the clamping seat to cause the clamping seat to tend to move in the direction of closing the open slot under normal conditions, thereby maintaining the clamping state of the magnetic core.

[0020] According to one embodiment of the present invention, one of the first wire tail clamping mechanism and the second wire tail clamping mechanism is configured as a rotating opening and closing structure, which can rotate about a preset pivot axis to clamp or release the wire tail;

[0021] Another component of the first and second wire tail clamping mechanisms is a sliding opening and closing structure, which can slide along a preset guide direction to clamp or release the wire tail.

[0022] According to one embodiment of the present invention, the rotating opening and closing structure includes:

[0023] The receiving seat is provided with a clamping surface for supporting the end of the wire;

[0024] The rotating pressure plate is pivotally connected to the receiving seat, and one end of the rotating pressure plate is formed with a pressing part that matches the clamping surface;

[0025] The second elastic element acts on the rotating pressure plate so that the crimping part has a tendency to press against the clamping surface under normal conditions, thereby maintaining the clamping state of the wire tail.

[0026] The rotating pressure plate is configured to rotate around the preset pivot axis under the external force driving it to overcome the elastic force of the second elastic element, so that the pressing part moves away from the clamping surface to release the end of the line.

[0027] According to one embodiment of the present invention, the sliding opening and closing structure includes:

[0028] A sliding guide component is slidably engaged with the fixture base in the vertical direction, and the fixture base has a receiving surface;

[0029] A clamping element is connected to the top of the sliding guide;

[0030] The third elastic element acts on the sliding guide or the clamping element so that the clamping element has a tendency to press against the receiving surface under normal conditions, thereby maintaining the clamping state on the end of the line.

[0031] Under the external force that overcomes the elasticity of the third elastic element, the sliding guide slides upward along the fixture seat, thereby causing the clamping element to leave the receiving surface to release the thread tail.

[0032] According to one embodiment of the present invention, the wire clamping mechanism includes:

[0033] Base;

[0034] The lifting seat can move up and down relative to the base;

[0035] A linkage frame is fixed on the lifting seat, and the linkage frame has a centrally located positioning tongue;

[0036] Two rotating clamping arms are pivotally connected to the base and are distributed on both sides of the positioning tongue;

[0037] Two linkage arms are located on both sides of the linkage frame; one end of each linkage arm is pivotally connected to the linkage frame, and the other end is pivotally connected to the corresponding rotating clamping arm.

[0038] When the lifting seat is driven by external power to move the linkage frame up and down, the linkage frame drives the two rotating clamping arms to rotate around their pivot points on the base via the two linkage arms, so that the two rotating clamping arms converge toward the positioning tongue to clamp the wire end, or unfold away from the positioning tongue to release the wire end.

[0039] According to one embodiment of the present invention, the skeleton clamping mechanism includes two clamping components distributed on opposite sides of the fixture seat in a second direction;

[0040] Each of the clamping components includes:

[0041] A claw seat is disposed on the fixture seat;

[0042] The gripper is pivotally connected to the gripper seat. One end of the gripper is formed with a clamping part for abutting against the insulating frame, and the other end is formed with a force-bearing part.

[0043] The force-bearing portions of the two grippers are configured to rotate around their respective pivot points under external power, so that the clamping portions of the two grippers move closer to each other to clamp the insulating frame, or move further apart to release the insulating frame.

[0044] According to one embodiment of the present invention, the top surface of the fixing base is provided with a recessed groove, which provides clearance space for an external robotic arm when the insulating frame is assembled with the electromagnetic component.

[0045] On the other hand, the electromagnetic component multi-station rotary placement device according to an embodiment of the present invention includes:

[0046] The workbench has multiple processing stations along its circumferential direction;

[0047] A rotating disk is rotatably mounted on the worktable;

[0048] Multiple electromagnetic component fixtures as described above are distributed at intervals along the circumference of the rotary disk and pass through each of the processing stations in sequence as the rotary disk rotates;

[0049] Multiple external drive devices are respectively disposed at at least some of the processing stations;

[0050] When any of the electromagnetic element fixtures rotates with the rotary table to the corresponding processing station, the corresponding external drive device is used to selectively drive the fixture seat of the electromagnetic element fixture to open to release the magnetic core of the electromagnetic element, and / or drive the first wire tail clamping mechanism and the second wire tail clamping mechanism of the electromagnetic element fixture to perform opening and closing actions.

[0051] The electromagnetic component fixture and multi-station rotary loading device provided by the embodiments of the present invention, by arranging a first wire tail clamping mechanism and a second wire tail clamping mechanism at intervals around the fixture seat, and adapting their spatial distribution to the extension direction before and after the coil rotation and displacement, is beneficial to maintaining effective limit on the wire tail when the coil rotates to different postures, thereby helping to improve the consistency of the hanging and wire sorting processes. Simultaneously, by arranging multiple fixtures circumferentially along the rotary table and cooperating with external drive devices at the workstations, an automated layout is formed that separates the power source from the accompanying fixtures, reducing the non-processing time loss caused by frequent transfers in the traditional linear flow mode, and to a certain extent reducing the cumulative error caused by repeated component positioning. Furthermore, the fixtures have good versatility at various processing stations on the rotary table, and can meet the differentiated clamping or loosening requirements of different workstations through selective triggering of the external drive device, effectively adapting to diverse assembly process paths. Therefore, not only is the processing efficiency and assembly precision of the production line improved, but the overall equipment also tends to be lighter and more compact.

[0083] To more clearly illustrate the technical solution and practical application scenarios of the electromagnetic component fixture 200 provided in the embodiments of the present invention, the specific structure of the workpiece to be assembled using the fixture and the corresponding assembly process are briefly described here.

[0084] The workpiece to be processed mainly includes an electromagnetic element 100 and an insulating frame that cooperates with the electromagnetic element 100. Specifically, the electromagnetic element 100 typically includes a magnetic core 101 and a coil 102 wound on the magnetic core 101. The magnetic core 101 is a closed structure with two side posts. There are two coils 102, each wound on one of the two side posts, with each coil 102 extending at both ends to form a wire start 102a and a wire end 102b. The insulating frame, as an independent assembly, is equipped with multiple conductive pins, the number of which is usually the same as the number of wire start 102a and wire end 102b.

[0085] In the actual automated assembly process, the insulating frame needs to be assembled onto the magnetic core 101 of the electromagnetic component 100, and then the wire ends 102a and 102b of the coil 102 are respectively wound, hung and fixed on the corresponding conductive pins of the insulating frame to form a reliable electrical connection node in preparation for the subsequent tinning or soldering process.

[0086] The electromagnetic component fixture 200 and the multi-station rotary loading device of the present invention will now be described in detail with reference to the accompanying drawings.

[0087] Reference Figures 1 to 9 As shown, the electromagnetic component fixture 200 provided according to an embodiment of the present invention includes a fixture base 20, a skeleton clamping mechanism 21, a wire end clamping mechanism 22, a first wire end clamping mechanism 23 and a second wire end clamping mechanism 24.

[0088] Specifically, the fixture base 20 is used to support the electromagnetic element 100. The fixture base 20 is constructed as an openable structure to selectively clamp or release the magnetic core 101 of the electromagnetic element 100. In actual operation, the fixture base 20 is driven by an external force to open its internal space, facilitating the insertion or removal of the electromagnetic element 100. Once the electromagnetic element 100 is in place, the fixture base 20 performs a closing action, clamping the magnetic core 101 of the electromagnetic element 100, thereby providing a stable clamping force on the magnetic core 101 during processing, thus achieving reliable fixation of the electromagnetic element 100.

[0089] The skeleton clamping mechanism 21 is disposed on the side of the fixture base 20 and is used to clamp and limit the insulating skeleton during the assembly of the insulating skeleton and the electromagnetic component 100. In the assembly process of the insulating skeleton and the electromagnetic component 100, after the insulating skeleton and the magnetic core 101 of the electromagnetic component 100 are assembled together, the skeleton clamping mechanism 21 is controlled to perform an action, so that its working end abuts against the insulating skeleton, thereby clamping and fixing the assembled insulating skeleton and the electromagnetic component 100 to maintain the relative positional stability of the two in the assembled state.

[0090] The wire end clamping mechanism 22 is used to clamp the wire end 102a of the coil 102 on the electromagnetic element 100. The wire end clamping mechanism 22 is arranged in the peripheral area of ​​the fixture base 20 and can clamp and fix the wire end 102a of the coil 102 on the electromagnetic element 100.

[0091] The first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 are distributed at intervals along the periphery of the fixture seat 20. The spatial distribution between the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 is adapted to the extension direction of the wire tail 102b of the coil 102 before and after rotational displacement on the fixture seat 20, so that one of the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 can clamp the wire tail 102b of the coil 102 before rotational displacement, and the other of the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 can clamp the wire tail 102b of the coil 102 after rotational displacement.

[0092] In the assembly and mounting process of the electromagnetic component 100 and the insulating frame, there is a requirement for the coil 102 to rotate and reposition relative to the magnetic core 101. Specifically, the wire end 102a formed during the winding process of the coil 102 of the electromagnetic component 100 is relatively short. The short wire end 102a is not convenient for mounting, so it needs to be stretched into a long wire end before mounting. During the stretching of the wire end 102a, the coil 102 is subjected to tension and rotates. Correspondingly, the wire tail 102b at the other end of the coil 102 also rotates, thereby changing the position of the wire tail 102b. This process is called the rotational repositioning of the coil 102.

[0093] In embodiments of the present invention, a first wire tail clamping mechanism 23 and a second wire tail clamping mechanism 24 are configured. When the coil 102 is in its initial posture before rotational displacement, one of the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 (e.g., the first wire tail clamping mechanism 23) is positioned at a location intersecting with the natural extension trajectory of the wire tail 102b in the initial posture, and performs a clamping action to clamp and position the wire tail 102b of the coil 102 before rotational displacement. When the coil 102 rotates to a new processing posture, its wire tail 102b rotates to a new extension direction. At this time, the other of the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 (e.g., the second wire tail clamping mechanism 24) is positioned precisely on the extension trajectory of the wire tail 102b after displacement, and performs a clamping action to clamp and position the wire tail 102b of the coil 102 after rotational displacement.

[0094] The operation process of the electromagnetic component fixture 200 according to an embodiment of the present invention will be described below with reference to the actual assembly and processing technology.

[0095] After the magnetic core 101 completes the winding process to form the electromagnetic element 100, the electromagnetic element 100 is placed in the fixture 20 by an external transfer device such as a robotic arm. Subsequently, the fixture 20 is externally driven to perform a closing action to stably clamp and position the magnetic core 101 of the electromagnetic element 100. Simultaneously or sequentially as the magnetic core 101 is positioned and clamped, one of the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 distributed around the fixture 20, such as the first wire tail clamping mechanism 23, is controlled to perform a closing action, thereby clamping and fixing the wire tail 102b of the coil 102 in its initial naturally extended state.

[0096] As the fixture carrying the electromagnetic element 100 moves to the next processing station, the process requires an external wire-pulling mechanism to lengthen the wire end 102a of the coil 102 to provide sufficient lead length for subsequent mounting. During this pulling action, to accommodate the rotation of the coil 102 during the pulling action, the first wire-end clamping mechanism 23 is first released in a controlled manner to release the constraint on the wire end 102b; subsequently, the external wire-pulling mechanism lengthens the wire end 102a. During the lengthening action, the coil 102 rotates and shifts around the magnetic core 101, and the wire end 102b of the coil 102 rotates synchronously in both angle and position. Because the spatial distribution between the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 is pre-configured to match the extension direction of the wire tail 102b before and after the coil 102 is rotated and repositioned, when the coil 102 is rotated and repositioned, the wire tail 102b rotates precisely into the working area of ​​the second wire tail clamping mechanism 24. At this time, the second wire tail clamping mechanism 24 is controlled to perform a closing action, re-clamping the rotated and repositioned wire tail 102b; at the same time, the wire end clamping mechanism 22 set on the fixture also operates synchronously or sequentially, clamping and fixing the elongated wire end 102a. In this way, through the above process, both the wire end 102a and the wire tail 102b of the coil 102 obtain independent and definite clamping constraints.

[0097] After completing the coil 102 rotation and double-bundle lead clamping process, the fixture carrying the electromagnetic element 100 flows into the next assembly station. At this station, the main task is to assemble the insulating frame. Specifically, an external assembly robot is used to orient and precisely insert the insulating frame onto the magnetic core 101 of the electromagnetic element 100. After the assembly is completed, the frame clamping mechanism 21, located beside the fixture seat 20, moves inward under control to clamp and limit the assembled insulating frame, thereby tightly clamping and fixing the insulating frame to the magnetic core 101 of the electromagnetic element 100. Through this continuous coordinated action, the magnetic core 101, insulating frame, wire end 102a, and wire end 102b of the electromagnetic element 100 are all securely constrained by the fixture. Finally, the fixture can carry the assembled electromagnetic element 100 to the subsequent lead-hanging station for subsequent lead-hanging processing.

[0098] According to the embodiment of the present invention, the electromagnetic component fixture 200, by arranging a first wire tail clamping mechanism 23 and a second wire tail clamping mechanism 24 at intervals around the fixture base 20, and adapting their spatial distribution to the extension direction of the coil 102 before and after rotational displacement, facilitates the effective limiting of the wire tail 102b when the coil 102 rotates to different postures, thereby helping to improve the consistency of the hanging and wire arrangement processes. Simultaneously, by arranging multiple fixtures circumferentially along the rotary table 400 and cooperating with external drive devices at the workstations, an automated layout is formed that separates the power source from the accompanying fixtures. This reduces the non-processing time loss caused by frequent transfers in the traditional linear flow mode, and to a certain extent reduces the cumulative error caused by repeated component positioning. Furthermore, the fixtures have good versatility at various processing stations on the rotary table 400, and can meet the differentiated clamping or loosening requirements of different workstations through selective triggering of the external drive device, effectively adapting to diverse assembly process paths. Therefore, this not only improves the processing efficiency and assembly precision of the production line, but also makes the overall equipment more lightweight and compact.

[0099] Reference Figure 2 As shown, in some embodiments of the present invention, the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 are respectively disposed on opposite sides of the fixture seat 20 in a first direction. The first direction can be defined as the length direction or the width direction of the fixture seat 20. This distribution allows the wire tail 102b to rotate 180° during rotational displacement, and its physical trajectory can be maintained within the area covered by the first direction.

[0100] The wire end clamping mechanism 22 is disposed between the first wire end clamping mechanism 23 and the fixture seat 20, or between the second wire end clamping mechanism 24 and the fixture seat 20, so that the first wire end clamping mechanism 23, the wire end clamping mechanism 22, the fixture seat 20, and the second wire end clamping mechanism 24 are arranged in a straight line in space.

[0101] The skeleton clamping mechanism 21 is located on both sides of the fixture seat 20 in the second direction, and the first direction is perpendicular to the second direction, so that the skeleton clamping mechanism 21 and the first line end clamping mechanism 23, the line end clamping mechanism 22 and the second line end clamping mechanism 22 arranged in a straight line present a cross-shaped layout in space.

[0102] By employing the aforementioned spatial arrangement of cross-shaped and nested lines, high-density functional integration of the fixture is achieved within a limited space. This not only significantly reduces the overall size of the fixture but, more importantly, ensures that the wire clamping action and the skeleton clamping action operate independently without spatial overlap, thereby improving the anti-interference capability of each mechanism's operation.

[0103] Reference Figures 5 to 6 As shown, in one embodiment of the present invention, the jig base 20 includes a fixed base 201, a clamping base 202, and a first elastic member. The fixed base 201 is provided with an open slot H201. The cross-sectional shape of the open slot H201 is configured to match the shape of the magnetic core 101 of the electromagnetic element 100, so that when the lower end of the electromagnetic element 100 is inserted into the open slot H201, the magnetic core 101 is just engaged in the open slot H201, maintaining stability and preventing wobbling.

[0104] The clamping seat 202 is disposed opposite to the fixed seat 201, and the clamping seat 202 is movably configured on the open side of the open slot H201 to open or close the open slot H201, thereby releasing or clamping the magnetic core 101 of the electromagnetic element 100 placed in the open slot H201. In terms of the mating relationship, a linear sliding guide structure is provided between the clamping seat 202 and the fixed seat 201. For example, the fixed seat 201 has a guide hole, and the clamping seat 202 has a guide post that slides in conjunction with the guide hole, ensuring that the clamping seat 202 can only slide in a single direction, thus enabling the smooth and non-deflecting opening or closing of the open slot H201. In an alternative implementation, the movable configuration of the clamping seat 202 can also adopt a pivot structure, that is, one end of the clamping seat 202 is hinged to one side of the fixed seat 201 by a pin, and the opening or closing of the open slot H201 is achieved by rotating and swinging about the pin. The clamping seat 202 has a pressing surface on the side facing the open slot H201, thereby loosening or clamping the magnetic core 101 of the electromagnetic element 100 placed in the open slot H201.

[0105] A first elastic element acts on the clamping seat 202, causing the clamping seat 202 to tend to move in the direction of closing the open slot H201 under normal conditions, thereby maintaining the clamping state of the magnetic core 101. Exemplarily, the first elastic element can be a cylindrical helical compression spring, with one end of a guide post penetrating the fixed seat 201 along a first direction and connected to the clamping seat 202. The other end of the guide seat is provided with an actuating block. One end of the first elastic element abuts against the fixed seat 201, and the other end abuts against the actuating block. Under normal conditions without external intervention, the first elastic element maintains a certain degree of deformation, causing the clamping seat 202 to be subjected to a continuous tensile force, thus tending to move in the direction of closing the open slot H201, and maintaining the clamping state of the magnetic core 101 by relying on this tensile torque. In the actual application operation steps, when it is necessary to insert the magnetic core 101, the external driving mechanism (such as a cylinder) applies a force to the action block to overcome the elastic force of the first elastic element, forcing the clamping seat 202 to slide back along the guide groove, so that the open groove H201 is in the open state; then, the magnetic core 101 is placed into the open groove H201; finally, the external driving mechanism removes the force, the first elastic element releases potential energy and pushes the clamping seat 202 back, so that its pressing surface clamps the magnetic core 101.

[0106] By adopting the above-mentioned combination structure of clamping seat 202 and fixing seat 201 with continuous clamping force provided by the first elastic element, the mechanical normally closed clamping of the jig seat 20 is realized, so that the jig can maintain reliable fixation of the magnetic core 101 by mechanical elastic force without relying on an external power source during the transfer process.

[0107] Reference Figures 2 to 7 As shown, in one embodiment of the present invention, one of the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 is configured as a rotating opening and closing structure, capable of rotating about a preset pivot axis to clamp or release the wire tail 102b. The rotating opening and closing structure ensures greater clearance space in the open state. When the user or automated robot loads the electromagnetic element 100 onto the fixture base 20, the naturally extending wire tail 102b of the electromagnetic element 100 can smoothly and unobstructedly enter the working area of ​​the rotating opening and closing structure without mechanical interference. Subsequently, the rotating opening and closing structure closes, completing the clamping and fixing of the wire tail 102b.

[0108] Another configuration of the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 is a sliding opening and closing structure, which can slide along a preset guide direction to clamp or release the wire tail 102b. For example, the sliding opening and closing mechanism slides and opens and closes in the vertical direction. When the first wire tail clamping mechanism 23 is released and the coil 102 begins to perform a rotational displacement process, the coil 102 mainly rotates within the horizontal plane on the fixture seat 20, and the extended wire tail 102b also sweeps and rotates in a fan shape within the horizontal plane. At this time, because the sliding opening and closing structure has a laterally open working gap, the rotating wire tail 102b, when translating and sweeping within the horizontal plane, can smoothly and directly enter the working area of ​​the sliding opening and closing structure from the side without crossing structural obstacles and without mechanical interference. When the wire tail 102b has rotated to its position, the sliding opening and closing structure slides downward to reset, pressing and clamping the wire tail 102b.

[0109] The heterogeneous design, combining the aforementioned rotary opening and closing structure with a sliding opening and closing structure, effectively adapts to the lead wire movement trajectory of the electromagnetic component 100 at different stages. The rotary opening and closing structure utilizes an arc-shaped movement trajectory to provide ample clearance for the initial vertical feeding, reducing the risk of feeding interference; the sliding opening and closing structure utilizes a linear lifting trajectory to provide a laterally unobstructed guide channel for the rotational displacement of the coil 102 in the horizontal plane, conforming to the horizontal sweeping path of the wire tail 102b with a relatively simple mechanical structure. The combination of the two optimizes the force and interference avoidance of the local structure during action switching, ensuring the smoothness and positioning reliability of the wire tail 102b during the transfer between the first clamping mechanism and the second clamping mechanism.

[0110] It should be noted that in other embodiments of the present invention, depending on the actual fixture space layout constraints or the movement path requirements of the mechanism, the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 can both be constructed as rotational opening and closing structures, or both can be constructed as sliding opening and closing structures. Regardless of whether a completely isomorphic rotational design, sliding design, or the aforementioned heterogeneous combination structure is adopted, as long as the reasonable design of the movement trajectory and the avoidance of spatial interference can ensure that the wire tail 102b can smoothly and unobstructedly enter its corresponding working area during the full dynamic operation process of the electromagnetic element 100 being vertically placed into the fixture seat 20 and the coil 102 rotating and changing position in the horizontal plane, and that there is no structural interference with the mechanical parts on the fixture, it is acceptable.

[0111] Reference Figure 4 and Figure 7 As shown, in one embodiment of the present invention, the rotating opening and closing structure includes a receiving seat 231, a rotating pressure plate 232 and a second elastic member 233. The receiving seat 231 has a clamping surface S23 for supporting the tail of the wire 102b. For example, the top surface of the receiving seat 231 extends to form the clamping surface S23 for supporting the tail of the wire 102b.

[0112] A rotating pressure plate 232 is pivotally connected to the receiving seat 231. One end of the rotating pressure plate 232 has a pressing portion 2321 that mates with the clamping surface S23. A second elastic member 233 acts on the rotating pressure plate 232 so that the pressing portion 2321 has a tendency to press against the clamping surface S23 under normal conditions, thereby maintaining the clamping state on the thread tail 102b.

[0113] The rotating pressure plate 232 is configured to rotate around the preset pivot axis under the external force driving it to overcome the elastic force of the second elastic member 233, so that the pressing part 2321 moves away from the clamping surface S23 to release the wire tail 102b.

[0114] For example, the receiving seat 231 has a vertically extending sliding groove inside, and the sliding groove has a floating member 234 that can slide up and down. The rotating pressure plate 232 has a generally L-shaped structure, with a pressing part 2321 forming at one end that matches the clamping surface S23, and the other end extending to form a force-receiving driving end, which is pivotally connected to the receiving seat 231 via a pin. At the same time, a notch is formed at a set distance between the force-receiving driving end and the pivot position, and the notch is preferably U-shaped or elongated. A pin 235 is fixedly provided on the floating member 234, and the pin 235 passes through the notch. The second elastic member 233 is a helical compression spring, the lower end of which is limited and abuts against the inner wall of the bottom of the receiving seat 231, and the upper end directly abuts against the bottom surface of the floating member 234.

[0115] Under normal conditions without external intervention, the second elastic element 233 is in a pre-compressed state and continuously applies an upward elastic pushing force to the floating element 234, driving the floating element 234 to remain at a set high position. At this time, the pin 235 on the floating element 234 is at the high position and pushes upward against the inner wall of the notch of the rotating pressure plate 232. Since there is a lever arm between the force point of the notch and the pivot position, the pin 235 forces the pressing part 2321 of the rotating pressure plate 232 to deflect towards the clamping surface S23, thereby achieving and maintaining a tight clamping of the wire tail 102b.

[0116] In actual operation, when it is necessary to open the rotating pressure plate 232, the user applies downward external pressure to the floating member 234, and the floating member 234 then overcomes the elastic force of the second elastic member 233 and slides downward. During this downward movement, the pin 235 moves downward synchronously and acts on the bottom edge of the notch. By pulling the notch, the rotating pressure plate 232 rotates in the opposite direction around the pivot point, thereby moving the pressing part 2321 away from the clamping surface S23, which can release the wire tail 102b or allow the wire tail 102b to be inserted into it.

[0117] In this embodiment, the rotating opening and closing structure, with the lever-type pivot engagement of the rotating pressure plate 232 and the second elastic element 233, achieves normalized clamping of the wire tail 102b. This structural layout shortens the transmission path, transforms simple clamping into torque balance, and improves the smoothness and reliability of the clamping operation of the wire tail 102b.

[0118] It is understandable that the opening and closing of the rotating pressure plate 232 can also be achieved using other structures. For example, the second elastic element 233 can be a torsion spring. The first torsion arm of the torsion spring is fixed to the receiving seat 231, and the second torsion arm is applied to the rotating pressure block. Under normal conditions, the preload of the torsion spring is continuously converted into torque that drives the rotating pressure plate 232 to rotate, so that the pressing part 2321 has a tendency to press against the clamping surface S23, thereby maintaining a stable clamping state on the wire tail 102b.

[0119] Reference Figure 5 and Figure 6 As shown, in one embodiment of the present invention, the sliding opening and closing structure includes a sliding guide 242, a pressing member 241 and a third elastic member. The sliding guide 242 slides in cooperation with the fixture seat 20 in the vertical direction. The fixture seat 20 has a receiving surface, for example, the top surface of the fixture seat 20 is formed with the receiving surface.

[0120] The clamping member 241 is connected to the top of the sliding guide member 242. A third elastic member acts on the sliding guide member 242 or the clamping member 241 so that the clamping member 241 has a tendency to press against the receiving surface under normal conditions, thereby maintaining the clamping state of the line tail 102b.

[0121] Driven by an external force that overcomes the elasticity of the third elastic element, the sliding guide 242 slides upward along the fixture seat 20, thereby causing the clamping member 241 to leave the receiving surface to release the thread tail 102b.

[0122] For example, the sliding guide 242 is a rod, for example, with a square, rectangular, or polygonal cross-section structure with a guide plane. Correspondingly, the fixture seat 20 has a guide groove inside that matches the cross-sectional shape. The clamping member 241 is a sheet-like member, securely connected to the top of the rod to form a T-shaped structure. Preferably, the clamping member 241 and the sliding guide 242 are an integral structure. A driving block 243 is connected to the bottom of the rod, and the driving block 243 is located on the outside of the fixture seat 20. The third elastic member is a helical compression spring, one end of which abuts against the driving block 243, and the other end of which abuts against the fixture seat 20.

[0123] Under normal conditions, the third elastic element is in a pre-compressed state and continuously releases a downward thrust. This thrust causes the clamping element 241, connected to the top of the sliding guide 242, to tend to press against the receiving surface, thereby maintaining a stable clamping state on the thread tail 102b placed therebetween. When the user or an external drive mechanism applies an upward lifting force to the drive block 243, after overcoming the downward elastic force of the third elastic element, the sliding guide 242 slides upward, directly causing the clamping element 241 at the top to rise synchronously and thus leave the receiving surface; at this time, the thread tail 102b is released. When the above-mentioned lifting force is removed, the sliding guide 242 quickly falls back to its original position under the elastic restoring force of the third elastic element.

[0124] Through the linear guidance and elastic biasing of the sliding guide 242, the clamping member 241 and the third elastic member, the sliding opening and closing structure in this embodiment ensures that the clamping force applied by the clamping member 241 to the wire tail 102b acts vertically and evenly on the receiving surface. At the same time, the mechanical response of the entire clamping and releasing is rapid, smooth and reliable in positioning.

[0125] Reference Figure 8 and Figure 9 As shown, in some embodiments of the present invention, the wire clamping mechanism 22 includes a base 221, a lifting seat 222, a linkage frame 223 and two rotating clamping arms 225. The base 221 can be fixed relative to the fixed seat 201, or the base 221 and the fixed seat 201 can be integrated, with the base 221 being a part of the fixed seat 201.

[0126] The lifting seat 222 can move up and down relative to the base 221. For example, the lifting seat 222 is located below the base 221, and the top of the lifting seat 222 has a guide rod, while the base 221 has a guide hole that slides with the guide rod. The lifting seat 222 can be driven by a first driving member 226, such as a cylinder or a servo module.

[0127] The linkage frame 223 is fixed to the lifting seat 222, and the linkage frame 223 has a centrally located positioning tongue 2231. The linkage frame 223 is fixed to one side of the lifting seat 222 by screws or welding, and rises and falls synchronously with it. The positioning tongue 2231 of the linkage frame 223 is usually a long strip plate that extends upward, providing a reference positioning and rigid support for the inserted wire end 102a.

[0128] Two rotating clamping arms 225 are pivotally connected to the base 221 and distributed on both sides of the positioning tongue 2231. Two linkage arms 224 are located on both sides of the linkage frame 223; one end of each linkage arm 224 is pivotally connected to the linkage frame 223, and the other end is pivotally connected to the corresponding rotating clamping arm 225, thus forming a linkage-type clamping structure.

[0129] When the lifting seat 222 is driven by external power to move the linkage frame 223 up and down, the linkage frame 223 drives the two rotating clamping arms 225 to rotate around their pivot points on the base 221 via the two linkage arms 224, so that the two rotating clamping arms 225 converge toward the positioning tongue 2231 to clamp the wire end 102a, or unfold away from the positioning tongue 2231 to release the wire end 102a.

[0130] In practical use, when the lifting seat 222 is driven by external power, causing the linkage frame 223 to move upward in a straight line, the linkage frame 223 applies an upward oblique thrust to the two linkage arms 224 through the hinge points on both sides. This linear thrust is transmitted through the two linkage arms 224 and converted into torque on the two rotating clamping arms 225, causing the two rotating clamping arms 225 to rotate in opposite directions around their pivot points on the base 221, causing the clamping ends to converge synchronously towards the positioning tongue 2231, ultimately firmly clamping the wire end 102a between the rotating clamping arms 225 and the positioning tongue 2231. Conversely, when the lifting seat 222 is driven to reset downward, the linkage frame 223 moves downward and pulls the linkage arms 224, causing the rotating clamping arms 225 to unfold in the opposite direction away from the positioning tongue 2231, thereby completing the release operation of the wire end 102a.

[0131] Through the combination of multi-link linkage and positioning tongue 2231, the wire clamping mechanism 22 in this embodiment uses the linear motion of the lifting seat 222 as the single power input source. This is transformed into a transmission design where the symmetrically distributed linkage arms 224 simultaneously clamp the wire end 102a. This not only simplifies the drive structure but also makes the mechanical transmission path more compact and efficient, ensuring that the clamping force applied by the dual rotating clamping arms 225 to the wire end 102a remains dynamically symmetrical and balanced. Simultaneously, the centrally positioned positioning tongue 2231 provides a reliable support reference for the flexible wire end 102a, improving the reliability of the wire end 102a clamping.

[0132] In other embodiments of the present invention, the wire clamping mechanism 22 may also employ a linear relative motion clamping structure. For example, it may include a first sliding clamp and a second sliding clamp. A linear drive assembly, such as a bidirectional lead screw or cylinder, is disposed on the base 221. In actual operation, the linear drive assembly outputs a linear thrust, driving the first and second sliding clamps to slide synchronously towards or away from each other, thereby achieving the translational clamping or loosening action of the inserted wire end 102a.

[0133] Reference Figure 5 and Figure 6 As shown, in one embodiment of the present invention, the skeleton clamping mechanism 21 includes two clamping components distributed on opposite sides of the fixture seat 20 in a second direction.

[0134] Each of the clamping components includes a claw seat 211 and a gripper 212, with the claw seat 211 disposed on the jig seat 20. Exemplarily, the claw seats 211 in both clamping components can be formed as a single unit and fixed to the jig seat 20 by fasteners. Furthermore, it is understood that the jig seat 20 and the claw seats 211 can also be a single unit.

[0135] The gripper 212 is pivotally connected to the gripper base 211. One end of the gripper 212 is formed with a clamping part for abutting against the insulating frame, and the other end is formed with a force-bearing part.

[0136] The force-bearing portions of the two grippers 212 are configured to rotate around their respective pivot points under external power, so that the clamping portions of the two grippers 212 move closer to each other to clamp the insulating frame, or move further apart to release the insulating frame.

[0137] For example, the force-bearing parts of the two grippers 212 are pivotally connected to a U-shaped frame. The U-shaped frame 213 can be driven by a second drive component 214 such as a cylinder or a linear module, thereby driving the two grippers 212 to rotate synchronously to achieve the clamping or releasing operation.

[0138] When the clamping action is performed, the second drive component 214 acts synchronously on the force-bearing parts of the two grippers 212 through the U-shaped frame 213. This thrust, based on the lever principle, is converted into a rotational torque around their respective pivot points, forcing the two grippers 212 to rotate in opposite directions. This, in turn, causes the clamping parts of the two grippers 212 to move closer together from both sides until the centrally placed insulating frame is securely clamped and its freedom of movement is restricted. When a release operation is required, the external drive component reverses the drive, and the two grippers 212 rotate in opposite directions around the pivot points, causing the two clamping parts to move away from each other. At this time, the clamping space is opened, and the insulating frame can be released.

[0139] This embodiment employs a lever-type clamping structure with a symmetrical arrangement on both sides and based on pivot rotation. This smoothly transforms the purely linear external drive input into a centripetal clamping action that synchronously converges inward from both sides, ensuring that the clamping pressure applied to both sides of the insulating frame remains dynamically symmetrical and balanced. This not only effectively prevents frame position displacement that can easily be caused by unidirectional force application, but also, through proportional lever arm distribution, allows the mechanism to obtain a significantly amplified stable clamping force with a smaller external drive stroke, improving the positioning reliability of the insulating frame in subsequent processing stages.

[0140] It is understandable that the skeleton clamping mechanism 21 can also be implemented in other ways, such as using a multi-axis motion module to drive the grippers 212 to achieve direct clamping. For example, the grippers 212 can be fixed to the power output end of a multi-axis motion module (such as a servo linear slide). In actual operation, the multi-axis motion module directly drives the grippers 212 on both sides to move synchronously in opposite directions or away from each other along a straight trajectory according to preset control commands, thereby completing the clamping or releasing action on the insulating skeleton.

[0141] In some embodiments of the present invention, a groove H202 is provided on the top surface of the fixed base 201 to provide clearance space for an external robotic arm when the insulating frame is assembled with the electromagnetic element 100.

[0142] Specifically, the recess H202 is located in the area corresponding to the assembly of the insulating frame. During actual assembly, when an external robotic arm grips the insulating frame and assembles it with the electromagnetic component 100 on the fixed base 201, the recess H202 provides ample clearance for the robotic arm, preventing physical interference between the robotic arm and the fixed base 201. This ensures precise assembly of the insulating frame with the electromagnetic component 100, guaranteeing the accuracy of automated assembly and the safety of equipment operation.

[0143] Reference Figure 10 As shown, this embodiment of the invention also provides a multi-station rotary loading device, including a worktable 300, a rotary disk 400, a plurality of electromagnetic component fixtures 200 as described in the above embodiment, and a plurality of external drive devices.

[0144] Specifically, the worktable 300 has multiple processing stations along its circumference. A rotary disk 400 is rotatably mounted on the worktable 300. Multiple electromagnetic component fixtures 200 are distributed at intervals along the circumference of the rotary disk 400 and pass through each of the processing stations sequentially as the rotary disk 400 rotates.

[0145] Multiple external drive devices are respectively installed at at least some of the processing stations. The external drive devices can be cylinders, servo electric cylinders, etc.

[0146] When any of the electromagnetic element fixtures 200 rotates with the rotary disk 400 to the corresponding processing station, the corresponding external drive device is used to selectively drive the fixture seat 20 of the electromagnetic element fixture 200 to open to release the magnetic core 101 of the electromagnetic element 100, and / or drive the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 of the electromagnetic element fixture 200 to perform opening and closing actions.

[0147] In the specific process flow, the rotary disk 400 serves as a transfer carrier, driving the electromagnetic component fixture 200 through each processing station to complete continuous collaborative operations. First, when the fixture rotates with the rotary disk 400 to the first loading station, the external transfer robot places the wound electromagnetic component 100 into the fixture seat 20; subsequently, the external drive device corresponding to this station is controlled to intervene, driving the fixture seat 20 and the first wire tail clamping mechanism 23 to perform a closing action, thereby achieving the initial clamping and positioning of the magnetic core 101 and the wire tail 102b in the initial extension position.

[0148] Next, the rotary table 400 rotates again, carrying the fixture into the wire end 102a drawing station. At this station, the coil 102 rotates to adapt to the wire end 102a drawing process, and the various mechanisms work in dynamic coordination. The corresponding external drive device first drives the closed first wire tail clamping mechanism 23 to loosen, releasing the constraint of the wire tail 102b; then, the external drawing mechanism performs a lengthening action on the wire end 102a, causing the coil 102 and the wire tail 102b to rotate synchronously; when the wire tail 102b rotates to the working area of ​​the second wire tail clamping mechanism 24, the external drive device then drives the second wire tail clamping mechanism 24 and the wire end clamping mechanism 22 to perform a closing action synchronously or asynchronously, thereby completing the clamping of the rotated and repositioned wire tail 102b and the lengthened wire end 102a.

[0149] Subsequently, the rotary table 400 continues to rotate, transporting the fixture with the clamped leads to the assembly station. After the external robotic arm orients and inserts the insulating frame onto the magnetic core 101, the frame clamping mechanism 21 securely clamps the assembled insulating frame. Thus, through the station switching of the rotary table 400 and the sequential intervention of each external drive device, the magnetic core 101, wire end 102a, wire end 102b, and insulating frame of the electromagnetic component 100 all achieve defined spatial constraints on a single fixture, and finally flow smoothly with the rotary table 400 into the subsequent lead-hanging station for lead-hanging processing.

[0150] By employing the aforementioned multi-station rotary loading equipment, in conjunction with multiple fixtures on the rotary table 400 and externally mounted drive devices at each station, along with a dynamic-static separation control mode for external transfer and processing mechanisms, the inefficiency and secondary positioning errors caused by the reliance on multiple dedicated fixtures and frequent transfers in traditional linear flow layouts are resolved. This achieves one-stop attitude control and physical constraint of the electromagnetic component 100 in complex continuous assembly processes. Especially when handling the drawing process involving the dynamic rotation of the coil 102, the external drive devices are sequentially controlled to release and re-clamp the first wire tail clamping mechanism 23 and the second wire tail clamping mechanism 24 at preset positions. This achieves dynamic and precise adaptation and re-clamping of the shifted wire tail 102b caused by process operations, not only improving production efficiency but also ensuring extremely high positioning accuracy and positional consistency of the coil 102 lead before final attachment.
