Description

Technical Field

[0001] This utility model relates to the field of inductor winding machine technology, and in particular to an inductor winding machine. Background Technology

[0002] The wires of a wire-wound inductor form a coil on a magnetic core. When energized, it generates a magnetic field and stores energy, enabling it to perform functions such as low-pass / high-pass filtering and noise suppression in circuits. Compared to multilayer inductors, wire-wound inductors can use thicker wires and can withstand larger DC currents, making them suitable for high-current applications such as power conversion and switching power supplies. Wire-wound inductors can be manufactured using a circular winding method, where insulated copper wire is wound onto a ferrite or ceramic core according to the designed number of turns. For miniature wire-wound inductors, especially ceramic-core wire-wound inductors, the production process typically involves clamping the ceramic core at both ends before winding copper wire around it and then soldering it. However, the ceramic core is very small, and the clamping force at both ends can easily become unbalanced, causing the ceramic core to crack. Furthermore, this affects efficiency and product quality when producing products with thinner wire diameters. Taking the common 0603H wire-wound inductor as an example, its dimensions are 1.6mm*0.8mm*0.8mm. During the production of such small-sized ceramic miniature inductors, clamping cracks and misalignment during movement due to the thin wire diameter can result in many defective products. How to avoid clamping cracks and thin wire diameter issues is a technical problem that needs to be solved in this field. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Example:

[0034] like Figure 1As shown, an inductor winding machine includes a rotatable main rotating disk 13 mounted on a mounting base 10; the main rotating disk 13 is circumferentially fixed with a plurality of alternately arranged clamping devices 400 and wire clamping devices 500; it also includes a clamping control device 300 for controlling the clamping devices 400 to clamp or release ceramic cores 40; the clamping devices 400 clamp the ceramic cores 40 on one side; and it also includes a pressing device 600 cooperating with the clamping devices 400 for pressing against the ceramic cores 40; Both the clamping device 400 and the pressing device 600 act on the same end of the ceramic core 40. Through the cooperation of the clamping device 400 and the pressing device 600, clamping can be achieved on all four sides of one end of the ceramic core 40. Since only a single end of the ceramic core 40 is clamped, the problem of uneven force caused by double-end clamping is effectively avoided, and cracks can be effectively prevented. The mounting base 10 is also provided with a tensioner 20 for supplying wire and a winding device 30 for winding the inductor wire.

[0035] The main rotating disk 13 is a disk-shaped structure on which clamping devices 400 and wire clamping devices 500 are alternately arranged. These devices can be arranged sequentially and alternately, for example, one clamping device 400 followed by one wire clamping device 500, and so on. In this case, the number of clamping devices 400 and wire clamping devices 500 is the same. In one embodiment, one clamping device 400 can be arranged first, followed by two wire clamping devices 500, and then another clamping device 400 can be arranged, i.e., two wire clamping devices 500 are arranged between adjacent clamping devices 400. Both the clamping devices 400 and the pressing device 600 act on the ceramic. The same end of the core 40 can be understood as typically including a top surface 41 and a bottom surface 44 oppositely arranged, two side surfaces 43 oppositely arranged, and an end face 42 enclosed by the top surface 41, the bottom surface 44, and the side surfaces 43. The clamping device 400 can only act on the two side surfaces 43 and the bottom surface 44 to achieve initial clamping of the ceramic core 40. The pressing device 600 can further clamp by acting on the top surface 41, thereby effectively clamping the ceramic core 40 by limiting the four surfaces. In one embodiment, the clamping device 400 can also limit the end face 42 to ensure more freedom of movement during clamping. By clamping a single end of the ceramic core 40, additional The stress on the ceramic core 40 is more easily controlled, thus preventing cracking of the ceramic core 40. The core reason why existing technologies using clamping at both ends are prone to cracking is that the two spaced clamping components cannot guarantee that the forces applied to both ends of the ceramic core 40 are completely equal. Unequal forces will generate torsional or shear forces, which can easily cause cracking of the ceramic core 40 during machine operation vibrations. Furthermore, when fixing at both ends, effective alignment of the two clamping components is required, demanding high alignment precision. Uneven end faces 42 of the ceramic core 40 also directly affect the force difference between the two ends, thus placing higher demands on precision and control. This application… The single-end clamping method used can effectively solve the above problems. Single-end clamping can directly avoid the ceramic core 40 from being subjected to torsional or shearing forces. Although the ceramic core 40 will be subjected to torsional or shearing forces when the copper wire is wound, the force acting on the ceramic core 40 when the copper wire is wound is very small and not enough to cause the ceramic core 40 to crack. The tensioner 20 is a commonly used device in the art, used to provide the copper wire required for winding and to provide a certain tension when supplying the copper wire. Its specific structure and function are well known to those skilled in the art, and its specific structure will not be described in detail. The winder 30 is also a commonly used device in the art and has a variety of structural forms. After the ceramic core 40 is fixed, those skilled in the art can choose according to their needs.

[0036] like Figure 1-2As shown, in one embodiment, a main rotating shaft bearing seat 11 is fixedly provided on the mounting base 10; a main rotating shaft 12 is rotatably connected inside the main rotating shaft bearing seat 11; the main rotating shaft 12 is fixedly connected to the main rotating disk 13 to drive the main rotating disk 13 to rotate; a central tube 16 is provided in the middle of the main rotating shaft 12; the main rotating shaft 12 is configured to rotate freely around the central tube 16; a central tube fixing seat 15 is fixedly provided on the central tube 16; a central tube plate 14 is fixedly provided on the central tube fixing seat 15; the central tube plate 14 is disposed above the main rotating disk 13; a clamping control device 300, a pressing device 600, a wire pressing device 700, and a wire take-up device 900 are fixedly provided on the central tube plate 14.

[0037] The main rotating shaft 12 is hollow in the middle to accommodate the central tube 16. The rotation of the main rotating shaft 12 will not affect or be obstructed by the central tube 16. The central tube 16 can be fixedly connected to the mounting base 10, thereby achieving a relatively fixed position of the central tube plate 14. When the main rotating shaft 12 is driven to rotate, it can drive the main rotating disk 13 to rotate relative to the central tube plate 14, thus facilitating continuous operation. The driving device for the main rotating shaft 12... Figure 1 The shaft rotation is not shown in the figure. Those skilled in the art can drive the shaft rotation in various ways, and its specific structure will not be described in detail here. In one embodiment, the central tube plate 14 provides a support platform to facilitate the installation of the clamping control device 300, the pressing device 600, the wire pressing device 700, and the take-up device 900. When the installation positions of the clamping control device 300, the pressing device 600, the wire pressing device 700, and the take-up device 900 are relatively fixed, the number of these devices can be reduced. It can be understood that multiple clamping devices 400 and wire clamping devices 500 are equivalent to multiple workstations. When the position of the pressing device 600 is fixed, one pressing device 600 can be adapted to multiple clamping devices 400 to work.

[0038] like Figure 3 As shown, in one embodiment, the winding device 30 includes a winding device base 31; a movable seat 32 is slidably connected to the winding device base 31; a rotatable winding shaft 33 is provided on the movable seat 32; a wire guide 34 is eccentrically connected to the winding shaft 33; and a through wire passage 341 is provided inside the wire guide 34.

[0039] The sliding connection between the winding base 31 and the movable seat 32 can be achieved using a common guide rail slider structure. The drive can be a lead screw motor to achieve the linear reciprocating motion of the movable seat 32. By controlling the movement of the movable seat 32, the end of the lead wire 34 can be moved closer to or further away from the ceramic core 40, thus facilitating the winding of copper wire onto the ceramic core 40. The winding shaft 33 can be driven to rotate, thereby achieving the winding of the ceramic core 40. The lead wire 34 can preferably be disposed inside the winding shaft 33 to reduce space occupation, and the axis of the lead wire 34 is parallel to the […]. The winding shaft 33 is axially and eccentrically positioned. The lead wire 34 is essentially a hollow tube structure that works with the ceramic core 40. One end of the lead wire has an inner diameter slightly larger than the diameter of the copper wire, which reduces unintended displacement during copper wire winding. The working principle is as follows: a copper wire is threaded through the wire passage 341 of the lead wire 34. One end of the copper wire is connected to the tensioner 20, and the other end is clamped by the wire clamping device 500. When one end of the lead wire 34 approaches the ceramic core 40, the lead wire 34 rotates with the winding shaft 33. The trajectory of the head of the lead wire 34 is a circle, which allows the copper wire to be wound onto the ceramic core 40. After one ceramic core 40 is wound, the winding device 30 retracts. At this time, the height of the winding device 30 is the same as the height of the clamping device 500. The main rotating disk 13 rotates clockwise, and the copper wire can be clamped by the clamping device 500 behind the clamping device 400 that has already wound the copper wire, thus fixing the copper wire. After the clamping device 400 in the rear rotates into position, it can further wind the wire in the manner described above. After the ceramic core 40 that has already wound the wire enters the welding station after rotation, the welding device 800 welds and fixes the copper wire to the ceramic core 40.

[0040] like Figure 4As shown, in one embodiment of this utility model, the mounting base 10 is further provided with a feeding device 100 for providing ceramic core 40 and a loading device 200 for transferring ceramic core 40 from the feeding device 100 to the clamping device 400; the feeding device 100 includes a material tray 110 and a feeding channel 120; the loading device 200 includes a feeding plate 210 fixedly connected to the mounting base 10; a first cylinder 220 and a first guide rail 211 are fixedly mounted on the feeding plate 210; a first slider 212 is interactively connected to the first guide rail 211; a feeding moving plate 230 is fixedly connected to the first slider 212; the cylinder shaft of the first cylinder 220 passes through a first push block 22. 1. Fixedly connected to the feeding moving plate 230; the feeding moving plate 230 is fixedly provided with a second cylinder 240 and a second guide rail 231; a second slider 232 is slidably connected to the second guide rail 231; a clamping moving frame 250 is fixedly connected to the second slider 232; the cylinder shaft of the second cylinder 240 is fixedly connected to the clamping moving frame 250 through a second push block 241; a third cylinder 260 is fixedly provided on the clamping moving frame 250; the cylinder shaft axis of the first cylinder 220 is perpendicular to the cylinder shaft axis of the second cylinder 240 and also perpendicular to the cylinder shaft axis of the third cylinder 260; the cylinder shaft axis of the second cylinder 240 is perpendicular to the cylinder shaft axis of the third cylinder 260.

[0041] The feeding device 100 is also a common device in the field, usually an automatic feeding vibratory feeder, which conveys the ceramic core 40 to the feeding channel 120 for later use. The loading device 200 is actually a three-degree-of-freedom robot, which can transfer the ceramic core 40 in the feeding channel 120 to the clamping device 400. In this embodiment, the three degrees of freedom in the loading device 200 are achieved by cylinder drive. The first push block 221 is a connecting component connecting the first cylinder 220 and the feeding moving plate 230, and the second push block 241 is a connecting component connecting the second cylinder 240 and the clamping moving frame 250. Its main function is to achieve a fixed connection. The cylinder shaft of the third cylinder 260 is usually equipped with a suction cup or other structure for gripping or releasing the ceramic core 40.

[0042] like Figure 5-7 As shown, the clamping control device 300 includes a clamping opening bracket 310; a fourth cylinder 320 is fixedly mounted on the clamping opening bracket 310; a movable clamping plate 330 is rotatably connected to the cylinder shaft of the fourth cylinder 320; the movable clamping plate 330 is movably connected to the clamping opening bracket 310; a fixing hole 311 is provided on the clamping opening bracket 310; a rotating shaft is fixedly mounted in the fixing hole 311. Figure 6 (not shown in the image), it should be understood that the shaft is in Figure 6The paper is perpendicular to the paper surface and is set in the fixed hole 311; the movable clamping plate 330 is sleeved on the rotating shaft; the movable clamping plate 330 is provided with a movable hole 331 that cooperates with the rotating shaft; the diameter of the movable hole 331 is larger than the diameter of the rotating shaft so that the movable clamping plate 330 can rotate relative to the rotating shaft under the drive of the fourth cylinder 320; the clamping device 400 includes a tooling base 410 fixedly connected to the main rotating disk 13; the tooling base 410 A clamping pad 420 is fixedly provided on the 10; a fixed clamp 430 is fixedly provided on the clamping pad 420; a movable clamp 440 is rotatably connected to the clamping pad 420; a fixed clamping pressure plate 450 is fixedly provided on the top of the fixed clamp 430; a clamping groove 431 is formed at one end of the fixed clamp 430; a clamping surface 441 that mates with the clamping groove 431 is provided on the movable clamp 440; a compression spring is connected to the end of the movable clamp 440 away from the clamping surface 441. Figure 7 (not shown in the image). The compression spring acts on the movable clamp 440 so that the clamping surface 441 tends to approach the clamping groove 431; the ceramic core 40 is located in the clamping groove 431 and is abutted by the clamping surface 441 in the clamping state; the movable clamping plate 330 cooperates with the movable clamping plate 330 under the action of the fourth cylinder 320 to clamp or release the ceramic core 40.

[0043] The clamping control device 300 includes a clamping opening bracket 310 fixedly connected to the central tube plate 14. Typically, one clamping control device 300 is installed on the central tube plate 14; one is used to open the clamping device 400 during loading to facilitate the installation of the ceramic core 40, and the other is used to open the clamping device 400 after the ceramic core 40 has been processed into an inductor to achieve inductor retraction. The diameter of the movable hole 331 is larger than the diameter of the rotating shaft to avoid interference. Figure 6As shown, when the cylinder shaft of the fourth cylinder 320 moves downward, it pushes one end of the movable clamping plate 330 downward in a straight line. However, since the movable clamping plate 330 is sleeved on the rotating shaft, it will also rotate around the rotating shaft. If the size of the movable hole 331 is not increased, the linear movement of the cylinder shaft of the fourth cylinder 320 will interfere with the rotational movement of the movable clamping plate 330. When the size of the movable hole 331 is slightly larger than that of the rotating shaft, both movements can be achieved, which can effectively simplify the structure. When the cylinder axis of the fourth cylinder 320 moves upward, the movable clamping plate 330 rotates clockwise, further pressing against the movable clamp 440, causing the movable clamp 440 to rotate. The clamping surface 441 moves away from the clamping groove 431, thus providing space for the installation of the ceramic core 40. After the ceramic core 40 is placed, the fourth cylinder 320 drives the cylinder axis to move downward. The movable clamp 440 rotates under the action of the compression spring, and the clamping surface 441 moves closer to the clamping groove 431, thereby clamping the ceramic core 40.

[0044] The fixture pad 420 is provided to facilitate the installation of the fixed fixture 430 and the movable fixture 440. In one embodiment, the fixture pad 420 can also be integrated with the tooling base 410 to provide installation space for the fixed fixture 430 and the movable fixture 440. In this embodiment, the clamping groove 431 provided on the fixed fixture 430 can be a through groove or a non-through groove. Figure 7 As shown, when the clamping groove 431 is through, the bottom surface 44 of the ceramic core 40 can contact the clamping pad 420 through the clamping groove 431; when the clamping groove 431 is not through, the bottom surface 44 of the ceramic core 40 directly contacts the bottom of the clamping groove 431; at the same time, one side of the clamping groove 431 is an open structure and cooperates with the clamping surface 441; in one embodiment, the clamping pad 420 can be made of a flexible material, such as a silicone pad, which can achieve flexible contact with the ceramic core 40, especially when the pressing device 600 presses down against the ceramic core 40, it can effectively ensure that the force on the end of the ceramic core 40 is uniform and can also prevent the ceramic core 40 from cracking; furthermore, in order to ensure that the ceramic core 40 can abut against the clamping pad 420 during installation, the clamping groove 431 on the fixing clamp 430 should be a through groove, such as Figure 7 The middle part is continuous in the vertical direction; a fixing clamp plate 450 is fixedly provided on the top of the fixing clamp 430, and the fixing clamp plate 450, fixing clamp 430, clamp pad 420, and tooling base 410 can be fixed together with bolts; the rotatable connection between the movable clamp 440 and the clamp pad 420 is usually achieved by a rotating shaft, which is generally located in the middle of the movable clamp 440; the compression spring is in Figure 7Not shown, one end of the compression spring can be fixedly connected to the fixed clamp 430, and the other end is connected to the movable clamp 440; in one embodiment, one end of the compression spring can also be fixedly connected to the tooling base 410, and the other end is fixedly connected to the movable clamp 440; the compression spring can be understood as a spring that is always in a compressed state, so that the compression spring can continuously apply force to the movable clamp 440, and in the absence of other external interference, the compression spring can keep the clamping surface 441 always abutting against one side of the clamping groove 431; the compression spring acts on the movable clamp 440 to make the clamping surface 441 tend to move closer to the clamping groove 431, which can be understood as the clamping surface 441 having a tendency to move towards the clamping groove 431 under the action of force, that is, in Figure 7 It has a tendency to rotate counterclockwise; such as Figure 7 As shown, one end of the ceramic core 40 includes a top surface 41, an end surface 42, two oppositely arranged side surfaces 43, and a bottom surface 44. When one end of the ceramic core 40 is clamped, the end surface 42 and one side surface 43 abut against the two surfaces of the clamping groove 431, the bottom surface 44 abuts against the clamping pad 420, and the clamping surface 441 abuts against the other side surface 43 of the ceramic core 40.

[0045] like Figure 8 As shown, in one embodiment of this utility model, the wire clamping device 500 includes a fixed wire clamp 510 fixedly connected to the main rotating disk 13; a movable wire clamp 520 is provided above the fixed wire clamp 510; a spring pad 530 is fixedly connected to the fixed wire clamp 510; a spring pad 540 located above the movable wire clamp 520 is fixedly connected to the spring pad 530; the movable wire clamp 520 is clamped between the spring pad 540 and the fixed wire clamp 510 under the elastic force of the spring pad 540; one end of the movable wire clamp 520 extends beyond one end of the fixed wire clamp 510 to form a limiting part 521; a guide surface 511 is formed on the side of the fixed wire clamp 510 near the limiting part 521.

[0046] There is no direct connection between the movable wire clamp 520 and the fixed wire clamp 510. The movable wire clamp 520 is clamped between the fixed wire clamp 510 and the spring plate 540 by the compression of the spring plate 540, thus ensuring that the movable wire clamp 520 has the possibility of displacement. The principle of the wire clamping device 500 is to bring the copper wire into contact with the guide surface 511 and pull the copper wire towards the spring plate 530. Under the action of the guide surface 511 and the limiting part 521, the copper wire will slide between the movable wire clamp 520 and the fixed wire clamp 510 and be clamped, thereby achieving fixation. Usually, the copper wire is only fixed at a position not far behind the guide surface 511. The clamping of the copper wire by other wire clamping devices 500 can be automatically achieved by the operation of the equipment. Specifically, the position of the lead wire 34 is adjusted to the height of the guide surface 511. When the main rotating disk 13 rotates further, the copper wire can automatically slide into another wire clamping device 500 located behind it to achieve fixation.

[0047] like Figure 9 As shown, in one embodiment of this utility model, the pressing device 600 includes a pressing seat 610 fixedly connected to the central tube plate 14; a fifth cylinder 620 and a third guide rail 611 are fixedly connected to the pressing seat 610; a third slider 612 is slidably connected to the third guide rail 611; a pressing slider seat 640 is fixedly connected to the third slider 612; the cylinder shaft of the fifth cylinder 620 is fixedly connected to one end of the pressing slider seat 640 through a pressing slider push seat 630; a pressing sheet 650 is fixedly provided on one end of the pressing slider seat 640 away from the pressing slider push seat 630, which abuts against the top surface 41 of one end of the ceramic core 40.

[0048] The pressing device 600 is used to cooperate with the top surface 41 of the ceramic core 40 to further fix the ceramic core 40 and prevent displacement during the winding process. In one embodiment, the pressing sheet 650 can be made of a flexible material, such as silicone. In another embodiment, the pressing sheet 650 can be made of metal. In order to avoid damage to the ceramic core 40 caused by hard contact, a silicone pad can be set at the bottom of the pressing sheet 650 to achieve flexible contact with the ceramic core 40.

[0049] like Figure 10As shown, in one embodiment of the present invention, the wire pressing device 700 includes a wire pressing plate seat 710 fixedly connected to the central tube plate 14; a fourth guide rail 711 is fixedly connected to the wire pressing plate seat 710; a fourth slider 712 is slidably connected to the fourth guide rail 711; a mounting base 720 is fixedly connected to the fourth slider 712; a wire pressing bracket 730 is fixedly provided at the bottom of the mounting base 720; a wire pressing bracket shaft 740 is connected to the wire pressing bracket 730; the wire pressing bracket shaft 740... Each end is rotatably connected to a pressure plate 750; the bottom of the mounting base 720 is also fixedly provided with a counterweight shaft limiting block 760; the counterweight shaft limiting block 760 is provided with a pressure plate counterweight shaft 770; the pressure plate 750 is provided with a limiting groove 751 that engages with the pressure plate counterweight shaft 770; when the pressure plate 750 is subjected to force and rotates upward, the pressure plate 750 abuts against the pressure plate counterweight shaft 770 and the gravity of the pressure plate counterweight shaft 770 restricts the rotation of the pressure plate 750.

[0050] The function of the wire pressing device 700 is to press and break the copper wires at both ends of the ceramic core 40 to be welded, thereby separating the copper wires from the ceramic core 40. After the copper wires are wound around the ceramic core 40, the ceramic core 40 is rotated to the position of the welding device 800. The welding device 800 welds the two ends of the wound copper wires to the two ends of the ceramic core 40. At this time, the ceramic core 40 is clamped and fixed by the clamping device 400. The wire clamping devices 500 on both sides of the clamping device 400 fix the two ends of the copper wires wound on the ceramic core 40. At this time, the copper wires are fixed by the two wire clamping devices 500 and wound around the two wire clamping devices 500. On the ceramic core 40 held by the clamping device 400 in the middle of the 00, one end of the copper wire is connected to the lead wire 34. When the welding device 800 performs welding, under normal circumstances, the welding device 800 can directly melt the copper wire during the welding process. However, in some cases, the copper wire may not be melted after welding. Therefore, the wire pressing device 700 is needed to assist in disconnecting the copper wire from the ceramic core 40. On the other hand, the copper wire falls slowly after being melted, which will affect the production effect. With the wire pressing device 700, the copper wire can be quickly pressed down to a hanging state after welding, which can effectively improve the production efficiency. The use of the counterweight shaft 770 on the pressure plate allows the force to increase linearly when the pressure plate 750 applies pressure to the copper wire, preventing direct breakage of the copper wire and vibration that could affect welding quality. When the pressure plate 750 presses down, the copper wire acts on the pressure plate 750, causing it to rotate upwards. This transfers the force to the counterweight shaft 770, increasing the force on the copper wire linearly until it separates from the ceramic core 40. The counterweight shaft 770 is typically supported by a counterweight shaft limiting block 760. When the pressure plate 750 acts on the counterweight shaft 770, the counterweight shaft 770 acts on the counterweight shaft limiting block 760. The force is reduced; the limiting groove 751 is usually set to be inclined. In the non-working state, the lower and rear of the pressure plate counterweight shaft 770 are limited by the counterweight shaft limiting block 760 and the mounting base 720 respectively, and the front of the pressure plate counterweight shaft 770 is limited by the inclined limiting groove 751, which can prevent the pressure plate counterweight shaft 770 from disengaging from the limiting groove 751. When the pressure plate 750 is working, the pressure plate 750 rotates backward, and the increasing inclination angle of the limiting groove 751 further enhances the limiting effect of the pressure plate counterweight shaft 770. Through this structural design, the connecting parts of the pressure plate counterweight shaft 770 can be reduced, making it convenient to replace.

[0051] like Figure 1As shown, in one embodiment of this utility model, a welding device 800 for welding copper wire to ceramic core 40 is further included; the welding device 800 includes a welding fixing seat 810 fixedly connected to the mounting base 10; a welding moving shaft 820 is slidably connected to the welding fixing seat 810; a first welding moving plate 830 is fixedly provided at one end of the welding moving shaft 820, and a second welding moving plate 840 is fixedly provided at the other end; a driving device for controlling the movement of the welding moving shaft 820 relative to the welding fixing seat 810 is provided on the first welding moving plate 830; a welding upper and lower moving seat 850 is movably connected to the second welding moving plate 840; a welding assembly for welding copper wire to ceramic core 40 is fixedly provided on the welding upper and lower moving seat 850.

[0052] Multiple welding moving shafts 820 can be arranged in parallel to ensure the linearity and stability of the movement. The driving device can be a cylinder or a lead screw motor. When the driving device is a cylinder, the cylinder is fixedly connected to the first welding moving plate 830, and the cylinder rod is fixedly connected to the welding fixed seat 810, thereby realizing the linear displacement control of the first welding moving plate 830. The same applies when using a lead screw motor. The welding upper and lower moving seat 850 can also be driven by a cylinder or a lead screw motor to realize the up and down displacement movement of the welding upper and lower moving seat 850. The welding assembly is a commonly used device in this field. Its function is to weld and fix the two ends of the copper wire to the two ends of the ceramic core 40 after the copper wire is wound on the ceramic core 40, thereby forming a complete wire-wound inductor. Those skilled in the art can also select according to their needs.

[0053] like Figure 11 As shown, in one embodiment of this utility model, the take-up device 900 includes a take-up release push rod seat 910 and a take-up base 940 fixedly connected to the central tube plate 14; a sixth cylinder 920 is fixedly connected to one end of the take-up release push rod seat 910 away from the central tube plate 14; a take-up release push rod 930 is rotatably connected to the cylinder shaft of the sixth cylinder 920; a take-up movable seat 950 is rotatably connected to one end of the take-up release push rod 930 away from the sixth cylinder 920; a take-up movable seat 950 is rotatably connected to one end of the take-up movable seat 950 away from the take-up release push rod 930 and the take-up base 940; a take-up release hook 960 cooperating with the wire clamping device 500 is fixedly connected to the take-up movable seat 950; the take-up device 900 also includes a needle-type cylinder mounting seat 970 fixedly connected to the mounting base 10; a needle-type cylinder 980 located below the wire clamping device 500 is fixedly connected to the needle-type cylinder mounting seat 970.

[0054] The function of the take-up device 900 is to collect the copper wire that has been broken or pushed downward by the wire clamping device 700 after welding. The function of the needle-type cylinder 980 is to push upward on the wire clamping device 500, so that a gap is created between the movable wire clamp 520 and the fixed wire clamp 510, thereby putting the copper wire in a non-clamped state. Then, the rotation of the take-up hook 960 separates the copper wire from the wire clamping device 500. When the cylinder axis of the sixth cylinder 920 extends outward, the take-up hook push rod 930 pushes the take-up movable seat 950 downward. The take-up movable seat 950 rotates downward, which in turn drives the take-up hook 960 to rotate downward, thereby separating the unclamped copper wire from the wire clamping device 500 and realizing the collection.

[0055] Working principle: The feeding device 100 conveys the ceramic core 40 into the feeding channel 120, and the loading device 200 transfers the ceramic core 40 to the clamping device 400. During the transfer, the clamping control device 300 rotates the clamping surface 441 of the movable clamp 440 away from the clamping groove 431 to facilitate loading by the loading device 200. After loading, the clamping control device 300 does not apply pressure to the movable clamp 440. Under the action of the compression spring, the clamping surface 441 and the clamping groove 431 cooperate to clamp the ceramic core 40. The main rotating disk 13 rotates clockwise a certain distance, so that the clamping device 400 holding the ceramic core 40 is in position. Below the pressing device 600, the pressing device 600 operates, abutting against the top surface 41 of the ceramic core 40 to complete the final fixation; at the same time, the feeding device 200 transfers another ceramic core 40 to the clamping device 400 behind and fixes it; a copper wire is threaded in the wire passage 341 of the lead wire 34, one end of the copper wire is connected to the tensioner 20, and the other end is clamped by the wire clamping device 500 on the left side of the clamping device 400 that holds the ceramic core 40. When one end of the lead wire 34 approaches the ceramic core 40, the lead wire 34 rotates with the winding shaft 33, and the trajectory of the head of the lead wire 34 is a circle, so that the copper wire can be wound around the ceramic core 40. After one ceramic core 40 is wound, the winder 30 retracts, at which point the height of the winder 30 is the same as the height of the clamping device 500. The main rotating disk 13 rotates clockwise, allowing the copper wire to be clamped by the clamping device 500 behind the previously wound copper wire clamping device 400, thus fixing the copper wire. After the rear clamping device 400 rotates into position, further winding can be achieved in the aforementioned manner. The previously wound ceramic core 40 enters the welding station after rotation, and the welding device 800 welds the copper wire to the… The ceramic core 40 is welded and fixed, while the wire pressing device 700 presses down the copper wires at both ends of the ceramic core 40, causing the copper wires to separate from the ceramic core 40. The main rotating disk 13 rotates clockwise further, and the separated copper wires held on the wire clamping device 500 can be completely separated from the wire clamping device 500 through the wire take-up device 900, achieving effective recycling. The processed inductor can be unloaded in a subsequent station. Another clamping control device 300 can be used to open the clamping device 400, and the inductor can automatically fall into the collection container.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
