Description

Technical Field

[0001] This utility model relates to the field of coil winding technology, and in particular to a square coil winding device. Background Technology

[0002] Coils, as the core basic component for electromagnetic conversion, are widely used in electronic and electrical equipment such as transformers, inductors, motors, and various sensors. Based on their winding trajectory and spatial shape, coils can be mainly classified into circular, square, and special irregular shapes. Among them, square helical coils, with their regular geometric shape and concentrated magnetic flux distribution, have irreplaceable advantages in applications requiring suitable square installation spaces or specific magnetic field distributions. By controlling key parameters such as the number of turns, interlayer spacing, and helix angle, precise inductance characteristics and quality factors can be achieved with these coils. Therefore, specialized winding technologies and equipment for the efficient and precise forming of square helical coils have always been an important direction for technological development and innovation in the coil manufacturing industry.

[0003] Currently, the fabrication of square helical coils still relies to varying degrees on traditional winding methods. Purely manual winding requires a high level of operator skill, has relatively limited production efficiency, and faces challenges in ensuring coil corner accuracy, consistent turn spacing, and uniform overall helix angle. On the other hand, while some existing semi-automated winding equipment reduces labor intensity to some extent, key processes such as controlling the wire bending angle, automatically forming the helix angle, and especially subsequent processes like wire cutting and collection, often still require manual assistance. This reliance on manual intervention not only restricts further improvements in production speed but also introduces quality fluctuations due to the uncertainty of human operation, and poses corresponding safety risks when operations involving cutting are involved. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a square coil winding device to solve the problems of low automation, insufficient product consistency, low production efficiency and operational safety risks caused by the reliance on manual labor in the subsequent cutting and collection processes of square spiral coil winding.

[0005] To achieve the above objectives, this utility model provides a square coil winding device, including a base, a disc seat on the top of one side of the base, a channel at the center of the disc seat, a wire slidably inserted into the channel, and a wire outlet connected to one side of the channel for outputting the wire; a turntable rotatably connected to the base, a bending block on the top surface of the turntable for bending the wire; an angle guide plate on the top of the base, a fan-shaped groove on the side of the angle guide plate near the wire for changing the helix angle of the wire; a scissor mechanism slidably connected to the top of the base for cutting the wire, a roller rotatably connected to one side of the scissor mechanism for supporting and guiding the wound wire; and an auxiliary inclined plate on the top of the base away from the disc seat for sliding down the cut helical coil.

[0006] According to the technical solution provided in this application example, an extension tube is also connected between the disc base and the outlet nozzle, and a collection box is provided on the top of the base for receiving the wound wire that falls from the auxiliary inclined plate.

[0007] According to the technical solution provided in this application example, a turntable seat is fixedly installed on the base, and a servo motor is installed inside the turntable seat. The output end of the servo motor is coaxially connected to the bottom of the turntable.

[0008] According to the technical solution provided in this application example, a support cap is coaxially connected to the top of the turntable for supporting the bent wire; an insert is installed on the top of the bending block for separating the upper and lower adjacent wires.

[0009] According to the technical solution provided in this application example, a pneumatic rod is provided on the base, and the output end of the pneumatic rod is connected to the scissor mechanism to drive the scissor mechanism and the roller to slide as a whole.

[0010] According to the technical solution provided in this application, a plurality of protrusions are vertically fixed on one side of the scissor mechanism, and the lap roller is rotatably inserted into all of the protrusions, with the lap roller being perpendicular to the traveling direction of the wire.

[0011] According to the technical solution provided in this application example, the side of the auxiliary inclined plate near the wire is an inclined surface, and a limiting groove is provided on the inclined surface to limit the wire that has been wound and slides along the surface of the auxiliary inclined plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. This square coil winding device, through the inclusion of a wire outlet, turntable, bending block, angle guide plate, and fan-shaped groove, achieves fully automated cyclic winding of square helical coils, from wire feeding, length setting, 90-degree bending, to obtaining the helix angle. This solution avoids inefficient and unstable manual operations, improves production efficiency, and ensures the controllability of the coil bending angle and the consistency of the helix angle through mechanical constraints, thereby significantly improving the product molding quality and yield.

[0014] 2. This square coil winding device, through the inclusion of a collection box, overlapping rollers, a shearing mechanism, and an auxiliary inclined plate, automatically triggers a series of sequential actions after coil winding is completed. The finished coil then automatically slides into the collection box, forming a closed-loop production process encompassing winding, cutting, and collection. This improves overall production efficiency, reduces labor costs, and significantly enhances operational safety by eliminating manual wire cutting and component handling. Attached Figure Description

[0028] like Figures 1-5 As shown, a square coil winding device includes a base 100, a disc seat 110 on the top of one side of the base 100, a channel at the center of the disc seat 110, a wire slidably inserted into the channel, and a wire outlet 112 connected to one side of the channel for outputting the wire; a turntable 210 rotatably connected to the base 100, a bending block 220 on the top surface of the turntable 210 for bending the wire; an angle guide plate 310 on the top of the base 100, a fan-shaped groove 311 on the side of the angle guide plate 310 near the wire for changing the helix angle of the wire; a scissor mechanism 430 slidably connected to the top of the base 100 for cutting the wire, a roller 440 rotatably connected to one side of the scissor mechanism 430 for supporting and guiding the wound wire; and an auxiliary inclined plate 450 on the top of the side of the base 100 away from the disc seat 110 for sliding down the cut helical coil.

[0029] The scissor mechanism 430 is existing technology and typically includes blades that move relative to each other and are connected by two cross axes, thereby enabling the cutting of wire.

[0030] Preferably, an extension tube 111 is connected between the disc base 110 and the outlet nozzle 112. The extension tube 111 and the outlet nozzle 112 can maintain the straightness of the wire's movement together. A collection box 120 is provided on the top of the base 100 to receive the wound wire that falls from the auxiliary inclined plate 450.

[0031] Preferably, a turntable base 200 is fixedly mounted on the base 100, and an insertion block 201 is detachably mounted on one side of the turntable base 200. A servo motor 202 is installed between the turntable base 200 and the insertion block 201, and the output end of the servo motor 202 is coaxially connected to the bottom of the turntable 210. It should be noted that a matching angle sensor is integrated at the servo motor 202 to facilitate bending the wire by 90 degrees when winding a square coil.

[0032] In this embodiment, as Figure 3 and Figure 4 As shown, a support cap 211 is coaxially connected to the top of the turntable 210. The upper part of the support cap 211 is a smooth curved hemispherical shape, which can always support the bottom of the spiral part of the wire while the wire is repeatedly bent into a spiral shape. A protruding strip 221 is provided on the side of the bending block 220 that is close to and aligned with the wire. An insert 230 is installed on the top of the bending block 220. The edge of the top surface of the insert 230 close to the wire has a rounded chamfer to facilitate insertion between adjacent wires to complete the separation. This ensures that when the bending block 220 bends the wire, it can only bend the bottommost wire without affecting the wires that have already been bent above. A series of grooves 240 are formed between the protruding strip 221 and the insert 230 to more fully limit the connection of the wire output from the outlet 112, thereby enhancing the reliability of bending the wire.

[0033] Preferably, a riser frame 400 is fixedly installed on one side of the base 100, and a slide block 401 is fixedly installed on the top of the riser frame 400. The slide block 401 is slidably connected to the slider 410 through the cooperation of the slide groove and the slide bar. A pneumatic rod 420 is installed at the end of the slide block 401 away from the scissor mechanism 430. The output end of the pneumatic rod 420 is fixedly connected to the slider 410. The scissor mechanism 430 is fixedly installed on the side of the slider 410 close to the wire. The pneumatic rod 420 controls the sliding of the scissor mechanism 430 by controlling the sliding of the slider 410.

[0034] In this embodiment, as Figure 5 As shown, at least two protrusions 431 are vertically fixed on one side of the scissor mechanism 430. The roller 440 is rotatably inserted into all the protrusions 431. A limiting protrusion ring 441 is fixedly sleeved between every two adjacent protrusions 431 to ensure that the roller 440 will not detach. The end of the roller 440 near the wire is pointed to facilitate smooth insertion under the wire. The roller 440 is perpendicular to the direction of travel of the wire.

[0035] Preferably, the side of the auxiliary inclined plate 450 closest to the wire is an inclined surface, and a limiting groove 451 is provided on the inclined surface. The groove walls on both sides are smooth arcs, and the distance between the two groove walls gradually decreases from bottom to top along the auxiliary inclined plate 450, decreasing to a fixed value that matches the width of the set square spiral coil. This allows the wound spiral coil to slide linearly along the surface of the auxiliary inclined plate 450, thereby facilitating the scissor mechanism 430 to vertically approach and cut the wire.

[0036] Working principle: Ensure the wire is output from the outlet 112. One side of the bending block 220 is aligned with the outlet 112. At this time, the bending block 220 is in its original position. The wire advances along one side of the bending block 220 until the wire output from the outlet 112 reaches the set length (or width). The outlet 112 stops outputting the wire. The turntable 210 rotates, causing the bending block 220 to rotate. The bending block 220 then bends the wire towards the angle guide plate 310. At the same time, the bottom of the wire contacts the fan-shaped groove 311, and the wire obtains a spiral angle. After the wire bends 90 degrees with the rotation of the bending block 220, the bending block 220 returns to its original position. At this time, the wire continues to be output until the wire output from the outlet 112 reaches the set width (or length). The above bending and spiral angle obtaining actions are repeated until the wire is wound to the set number of turns.

[0037] When a square spiral coil is wound, the wire output stops. The pneumatic rod 420 drives the roller 440 to slide between the spiral coil and the auxiliary inclined plate 450. At this time, the wire continues to output from the outlet 112, thereby driving the spiral coil forward onto the roller 440. Then it continues to move forward to ensure that the spiral part of the spiral coil is on the auxiliary inclined plate 450. After that, the pneumatic rod 420 drives the roller 440 to continue forward, and the shear mechanism 430 contacts and cuts the wire. Then the pneumatic rod 420 drives the roller 440 and the shear mechanism 430 to retract and disengage from the wire. After disengagement, the spiral coil on the auxiliary inclined plate 450 can slide down the auxiliary inclined plate 450 and enter the collection box 120.

[0038] Furthermore, it should be noted that the electrical connections of the servo motor (202), pneumatic rod (420), angle sensor, and controller involved in this utility model are conventional connection methods that can be achieved by those skilled in the art based on the above working principle, and will not be described in detail here.

[0039] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0040] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
