Chip electronic components primarily consist of magnetic cores, windings, and electrodes. The production of chip electronic components involves processes such as winding and welding.

Furthermore, traditional winding equipment requires frequent loading and unloading of workpieces and placement of workpieces at different processing stations. Frequent loading and unloading of the magnetic cores can easily lead to inaccurate core positioning or even core dropout, which in turn affects the efficiency and yield of chip electronic components.

[0041] Reference Figures 1 to 4The present invention discloses a patch-type electronic component winding machine, comprising a machine platform 100 and a loading device 300, a wire-releasing device 700, a wire-cutting device 800, a first rotary drive mechanism 400, a welding device 500, and a unloading device 600, all of which are arranged on the machine platform 100. The machine platform 100 is provided with a rotatable turntable 110, and a plurality of clamps 200 are evenly distributed on the outer edge of the turntable 110. The clamps 200 include a rotating shaft 210, a clamping mechanism 220, a plurality of front wire-straightening posts 230, and a plurality of rear wire-straightening posts. 240, the rotating shaft 210 is rotatably arranged on the turntable 110, the rotating shaft 210 is connected to the clamping mechanism 220, the plurality of front wire-arranging columns 230 and the plurality of rear wire-arranging columns 240, the rotating shaft 210, the clamping mechanism 220, the plurality of front wire-arranging columns 230 and the plurality of rear wire-arranging columns 240 can rotate around the same rotation center line, and the clamping mechanism 220 is used to clamp the magnetic core 10; the loading device 300, the first rotary drive mechanism 400, the welding device 500 and the unloading device 600 are arranged in sequence around the turntable 110 The loading device 300 is used to place the magnetic core 10 to be wound on the clamping mechanism 220; the unwinding device 700 is provided next to the first rotary drive mechanism 400, and the unwinding device 700 is used to unwind the wire; the first rotary drive mechanism 400 is connected to the first linear drive mechanism 410, and the first linear drive mechanism 410 is used to drive the first rotary drive mechanism 400 to move toward the turntable 110, so that the output end of the first rotary drive mechanism 400 is connected to the rotating shaft 210, and the first rotary drive mechanism 400 drives the rotating shaft 210 to rotate so that the magnetic core 10, multiple front wire-managing posts 230 and multiple rear wire-managing posts 240 are wound with wire, and the electrode end of the magnetic core 10 is against the wire; the wire cutting device 800 is arranged next to the wire-unwinding device 700, and the wire cutting device 800 is used to cut the wire wound on the magnetic core 10; the welding device 500 is used to weld the wire to the electrode end to obtain a chip electronic component; the unloading device 600 is used to remove the chip electronic component from the clamping mechanism 220 and stack it on the collection tray 610.

[0042] The turntable 110 drives the fixture 200 to rotate on the machine platform 100, causing the fixture 200 to sequentially pass through the positions corresponding to the loading device 300, the first rotary drive mechanism 400, the welding device 500, and the unloading device 600. When the fixture 200 moves to the position corresponding to the loading device 300, the loading device 300 places the magnetic core 10 on the clamping mechanism 220.

[0043] When the clamp 200 carries the magnetic core 10 and moves to the position corresponding to the first rotary drive mechanism 400, the first linear drive mechanism 410 drives the first rotary drive mechanism 400 to move toward the turntable 110, so that the output end of the first rotary drive mechanism 400 is connected to the rotating shaft 210. With the cooperation of the first rotary drive mechanism 400 driving the rotating shaft 210 to rotate and the unwinding device 700 unwinding the wire, the wire is wound around the magnetic core 10, multiple front wire management posts 230 and multiple rear wire management posts 240, and the electrode end of the magnetic core 10 is against the wire to complete the winding of the winding. Then the wire cutting device 800 cuts the wire wound on the magnetic core 10, and then the first linear drive mechanism 410 drives the first rotary drive mechanism 400 to move away from the turntable 110, so that the output end of the first rotary drive mechanism 400 is separated from the rotating shaft 210, and the turntable 110 drives the clamp 200 to rotate on the machine 100 again.

[0044] When the fixture 200 carries the magnetic core 10 and the wire on the magnetic core 10 and moves to the position corresponding to the welding device 500, the welding device 500 welds the wire and the electrode end together to obtain the required surface mount electronic component.

[0045] When the fixture 200 carrying the chip-type electronic components moves to the position corresponding to the unloading device 600 , the unloading device 600 removes the chip-type electronic components from the clamping mechanism 220 and stacks them on the collection tray 610 .

[0046] Reference Figure 4 and Figure 5 In some embodiments, the clamp 200 also includes a front wire head clamp 250 and a rear wire head clamp 260, both of which are connected to the rotating shaft 210. The rotating shaft 210, the front wire head clamp 250 and the rear wire head clamp 260 can rotate around the same rotation center line. The front wire head clamp 250, multiple front wire management posts 230, multiple rear wire management posts 240 and the rear wire head clamp 260 are arranged in sequence, and the magnetic core 10 clamped by the clamping mechanism 220 is between the multiple front wire management posts 230 and the multiple rear wire management posts 240.

[0047] Reference Figure 4 In some embodiments, there are three front wiring posts 230, which are spaced apart and arranged in a row, and four rear wiring posts 240, which are spaced apart and arranged in a row. Of course, the number of front wiring posts 230 and rear wiring posts 240 can be increased or decreased based on the winding requirements of the surface-mount electronic components, so that multiple layers of windings can be wound around the magnetic core 10.

[0048] The present invention also discloses a winding method for a patch type electronic component, comprising the following steps:

[0049] Fixing the wire end: The pay-off device 700 places the wire end on the rear wire end clamp 260, which clamps the wire end. Then, the pay-off device 700 wraps the wire around a rear wire management column 240;

[0050] Winding: The first rotary drive mechanism 400 drives the rotating shaft 210 to rotate, and the wire is wound around the magnetic core 10 in the forward direction. The first rotary drive mechanism 400 stops driving the rotating shaft 210 to rotate, and the pay-off device 700 winds the wire around a front wire-straightening post 230. The first rotary drive mechanism 400 drives the rotating shaft 210 to rotate again, and the wire is wound around the magnetic core 10 in the reverse direction. The first rotary drive mechanism 400 drives the rotating shaft 210 to stop rotating again, and the pay-off device 700 winds the wire around another rear wire-straightening post 240, and so on, until the wire is wound around the last rear wire-straightening post 240.

[0051] Fixing the wire tail: the wire-paying device 700 places the wire on the front wire head clamp 250 , the front wire head clamp 250 clamps the wire, and the wire cutting device 800 cuts the wire between the front wire head clamp 250 and the wire-paying device 700 .

[0052] When the wires are placed between the magnetic core 10 and the front and rear wire management posts 230 and 240 , they will rest against the corresponding electrode ends on the magnetic core 10 , making it easier for the welding device 500 to directly weld the wires and the electrode ends together to obtain the desired surface mount electronic components.

[0053] The turntable 110 drives the clamp 200 to pass through the areas corresponding to the loading device 300, the first rotary drive mechanism 400, the welding device 500 and the unloading device 600 in sequence, completing the loading of the magnetic core 10, winding the wire around the magnetic core 10, welding the wire and the electrode ends of the magnetic core 10 together, and placing the chip electronic components on the plate. It does not require excessive human intervention and is highly efficient. While liberating labor, it can also reduce errors in manual production of chip electronic components and improve the pass rate of chip electronic components.

[0054] Reference Figure 1 and Figure 2 In some embodiments, the pay-off device 700 includes a first drive mechanism and a pay-off tube. The first drive mechanism is provided on the machine 100, and the output end of the first drive mechanism is connected to the pay-off tube. The first drive mechanism is used to drive the pay-off tube to move in space, that is, to drive the pay-off tube to move in the front-back, left-right, and up-down directions, so that the pay-off tube can be placed in any position without interfering with other components. The pay-off tube allows the wire to pass through. When the wire passes through the pay-off tube, the first drive mechanism drives the pay-off tube to move, and the pay-off tube moves with the wire, allowing the wire to be placed on the front wire end clamp 250 and the rear wire end clamp 260, and also allowing the wire to be wound around the magnetic core 10, multiple front wire management posts 230, and multiple rear wire management posts 240, thereby achieving winding of the magnetic core 10.

[0055] It is understood that the unwinding device 700 also includes an unwinding mechanism and a wire clamping mechanism. The unwinding mechanism is provided on the machine 100 and is used to convey the wire to the unwinding tube. The wire clamping mechanism is provided at the output end of the first drive mechanism or on the unwinding tube. The wire clamping mechanism is used to clamp the wire so that the wire and the unwinding tube move synchronously. The number of unwinding tubes is one or two, and each unwinding tube corresponds to one wire. When the unwinding device 700 has two unwinding tubes, the unwinding device 700 can unwind two wires at the same time, so that the magnetic core 10 can be wound with two wires at the same time.

[0056] Furthermore, a second rotary drive mechanism is provided on the output end of the first drive mechanism, and the two pay-off tubes are connected to the output end of the first drive mechanism through the same bearing. The output end of the second rotary drive mechanism is transmission-connected to the two pay-off tubes. The second rotary drive mechanism drives the two pay-off tubes to rotate around a unified rotation center line, thereby realizing the interchange of the positions of the two pay-off tubes and the positions of the two wires.

[0057] The first driving mechanism can be a manipulator, or an XYZ axis moving mechanism, to drive the pay-off tube to move in space. Manipulators and XYZ axis moving machines are common devices on the market and will not be introduced here redundantly.

[0058] After the wire cutting device 800 cuts the wire between the front wire end clamp 250 and the wire unwinding device 700, the wire between the rear wire end clamp 260 and the magnetic core 10 becomes a wire end, and the wire between the front wire end clamp 250 and the magnetic core 10 becomes another wire end. The two wire ends will affect the appearance of the chip electronic components and the placement of the chip electronic components.

[0059] The welding device 500 is a common device on the market. Its structure, setting method and usage method are all known and will not be redundantly introduced here.

[0060] In some embodiments, the chip-type electronic component winding machine also includes a thread end collecting device 900, which is connected to the machine 100 and is arranged between the welding device 500 and the unloading device 600. The thread end collecting device 900 is used to cut the thread ends on the magnetic core 10 and collect the thread ends to obtain the required chip-type electronic components.

[0061] Reference Figure 1 and Figure 2In some embodiments, the thread end collecting device 900 includes a second driving mechanism, a first scissors, a first lifting driving mechanism and a straw 910. The second driving mechanism and the first lifting driving mechanism are both connected to the machine 100. The output end of the second driving mechanism is connected to the first scissors. The second driving mechanism is used to drive the first scissors to move in space, that is, to drive the first scissors to move in the front and back, left and right, and up and down directions, so that the first scissors can move to the position of the wire between the corresponding rear thread end clamp 260 and the magnetic core 10, and move to the position of the wire between the corresponding front thread end clamp 250 and the magnetic core 10, so that the first scissors can cut the thread end.

[0062] The output end of the first lifting drive mechanism is connected to the straw 910. The first lifting drive mechanism is used to drive the straw 910 to rise and fall. When the clamp 200 carries the surface-mount electronic component and moves to the position corresponding to the thread collection device 900, after the first scissors cut off the thread, the first lifting drive mechanism drives the straw 910 to descend. The straw 910 approaches the thread on the magnetic core 10 / clamp 200 and sucks away the thread cut by the first scissors. Then the first lifting drive mechanism drives the straw 910 to rise to prevent the straw 910 from interfering with the movement of the clamp 200.

[0063] In another embodiment, the thread end collection device 900 includes a second linear drive mechanism 920 and two first scissors. The output end of the second linear drive mechanism 920 is connected to the first scissors. The second linear drive mechanism 920 drives the two first scissors to move toward the turntable 110, so that the two first scissors are respectively moved to the position of the wire between the rear thread end clamp 260 and the magnetic core 10 and the position of the wire between the front thread end clamp 250 and the magnetic core 10. The two first scissors are respectively used to cut the two thread ends. After the two first scissors have cut the two thread ends respectively, the second linear drive mechanism 920 drives the two first scissors to move away from the turntable 110 to prevent the two first scissors from interfering with the clamp 200.

[0064] The thread trimming device 800 includes a second lifting drive mechanism mounted on the platform 100 and a second pair of scissors mounted at the output end of the second lifting drive mechanism. The second lifting drive mechanism is configured to drive the second pair of scissors to move upward and downward, enabling the second pair of scissors to cut the wire. In another embodiment, the thread trimming device 800 includes a fifth drive mechanism mounted on the platform 100 and a second pair of scissors mounted at the output end of the fifth drive mechanism. The fifth drive mechanism drives the second pair of scissors to move within a space.

[0065] Reference Figure 1 and Figure 2In some embodiments, the loading device 300 includes a vibration disk 310, a third drive mechanism, and a first clamping jaw. The vibration disk 310 and the third drive mechanism are both provided on the machine 100. The output end of the vibration disk 310 is provided with a first positioning block for positioning the magnetic core 10. A plurality of magnetic cores 10 to be wound are placed on the vibration disk 310. The vibration disk 310 outputs the plurality of magnetic cores 10 in rows to the output track of the vibration disk 310, and the magnetic cores 10 abut against the first positioning block, thereby completing the positioning of the magnetic cores 10. The output end of the third drive mechanism is connected to the first clamping jaw, and the third drive mechanism is used to drive the first clamping jaw to move in space, so that the first clamping jaw can move the magnetic core 10 abutting against the first positioning block to the clamping mechanism 220, thereby completing the loading of the magnetic core 10.

[0066] Reference Figure 3 and Figure 5 In some embodiments, the output end of the first rotation drive mechanism 400 is connected to the first adapter plate, and the clamp 200 also includes an adapter shaft 270 provided on the turntable 110, and the adapter shaft 270 is transmission-connected to the rotating shaft 210, and one end of the adapter shaft 270 is connected to the second adapter plate, and the first adapter plate and the second adapter plate are transmission-connected by cooperating tenons and grooves. When the first linear drive mechanism 410 drives the first rotation drive mechanism 400 to move toward the turntable 110, the first adapter plate and the second adapter plate approach each other, and the tenon is inserted into the groove to complete the connection between the first adapter plate and the second adapter plate. At this time, the first rotation drive mechanism 400 can drive the rotating shaft 210 to rotate through the first adapter plate, the second adapter plate and the adapter shaft 270, and when the first linear drive mechanism 410 drives the first rotation drive mechanism 400 to move away from the turntable 110, the first adapter plate and the second adapter plate move away from each other.

[0067] Reference Figure 1 and Figure 2 In some embodiments, the unloading device 600 includes a second clamping jaw and a fourth drive mechanism, a sliding table and a bracket, all of which are arranged on the machine 100. A second positioning block and a second linear drive mechanism are provided on the slide of the sliding table. The bracket is arranged next to the sliding table. The bracket is used to place several collection trays 610 side by side along the sliding direction of the sliding table. The output end of the fourth drive mechanism is connected to the second clamping jaw. The fourth drive mechanism is used to drive the second clamping jaw to move so that the second clamping jaw transports the chip electronic components on the clamping mechanism 220 to the second positioning block. When the chip electronic components are transported to the second positioning block, the slide of the sliding table carries the second positioning block, the chip electronic components and the second linear drive mechanism to the side of the collection tray 610 on the bracket. The output end of the second linear drive mechanism pushes the chip electronic components on the second positioning block into the collection slot of the collection tray 610, thereby completing the unloading of the chip electronic components or the collection of the chip electronic components or the placing of the chip electronic components on the tray.

[0068] The clamping mechanism 220 includes a first elastic member 221 and a first clamping arm 222 and a second clamping arm 223 that can be opened and closed. The first clamping arm 222 and the second clamping arm 223 are both connected to the rotating shaft 210. The first elastic member 221 is used to drive the first clamping arm 222 and the second clamping arm 223 to clamp one end of the magnetic core 1010.

[0069] It also includes a first clamping mechanism 120 and a second clamping mechanism, both of which are arranged on the machine 100. The first clamping mechanism 120 is arranged corresponding to the position of the loading device 300, and the second clamping mechanism is arranged corresponding to the position of the unloading device 600. The first clamping mechanism 120 and the second clamping mechanism are both used to drive the first clamping arm 222 and the second clamping arm 223 to open, so that the loading device 300 places the magnetic core 10 to be wound between the first clamping arm 222 and the second clamping arm 223, and the unloading device 600 removes the surface-mount electronic components clamped by the first clamping arm 222 and the second clamping arm 223.

[0070] A first adapter plate 211 is provided on the rotating shaft 210 . The axial direction of the rotating shaft 210 is parallel to the first adapter plate 211 . The rotating shaft 210 carries the first adapter plate 211 to rotate on the turntable 110 . The rotating shaft 210 and the first adapter plate 211 have the same rotation center line.

[0071] Reference Figure 4 and Figure 5 The clamp 200 also includes a support plate 212, the support plate 212, the first clamping arm 222 and the second clamping arm 223 are all arranged on the first adapter plate 211, the support plate 212 and the first adapter plate 211 are parallel to each other, the first clamping arm 222 and the second clamping arm 223 are both on the side of the support plate 212, the support plate 212 is used to support one end of the magnetic core 10, and the first elastic member 221 is used to drive the first clamping arm 222 and the second clamping arm 223 to clamp one end of the magnetic core 10. The support plate 212, the first clamping arm 222 and the second clamping arm 223 form a limiting groove for limiting one end of the magnetic core 10. When the first clamping arm 222 and the second clamping arm 223 are opened, the width of the limiting groove increases, and one end of the magnetic core 10 can be placed between the first clamping arm 222 and the second clamping arm 223, or the first clamping arm 222 and the second clamping arm 223 can be released from the magnetic core 10; and when the first clamping arm 222 and the second clamping arm 223 are closed, the first clamping arm 222 and the second clamping arm 223 can clamp one end of the magnetic core 10.

[0072] The clamp 200 also includes a top block 280, which can be raised and lowered on the turntable 110. The top block 280 is located in front of the first clamping arm 222 and the second clamping arm 223, that is, the top block 280 is located between the multiple front wiring posts 230 and the multiple rear wiring posts 240. The top block 280 is used to support the other end of the magnetic core 10.

[0073] When loading the magnetic core 10 into the clamp 200, the first clamping arm 222 and the second clamping arm 223 are first opened by using the first clamping mechanism 120, and then the two ends of the magnetic core 10 are respectively placed on the support plate 212 and the top block 280. Then the first clamping mechanism 120 stops acting on the first clamping arm 222 and the second clamping arm 223. Under the action of the first elastic member 221, the first clamping arm 222 and the second clamping arm 223 are closed together, and the first clamping arm 222 and the second clamping arm 223 can accurately and tightly clamp one end of the magnetic core 10. Before the first clamping arm 222 and the second clamping arm 223 are closed together, the support plate 212 and the top block 280 play the role of stably supporting the two ends of the magnetic core 10, and the position of the magnetic core 10 on the support plate 212 and the top block 280 can be adjusted at this time; in the process of the first clamping arm 222 and the second clamping arm 223 being closed together, since the magnetic core 10 is supported by the support plate 212 and the top block 280, it can be prevented from being offset and the magnetic core 10 falling off the fixture 200 due to being pushed by the first clamping arm 222 and / or the second clamping arm 223; when the first clamping arm 222 and the second clamping arm 223 tightly clamp one end of the magnetic core 10, the support plate 212 and the top block 280 can still play the role of supporting the magnetic core 10.

[0074] When the magnetic core 10 needs to be wound, the top block 280 descends and moves away from the first clamping arm 222 and the second clamping arm 223, and the rotating shaft 210 can carry the support plate 212, the first elastic member 221, the first clamping arm 222 and the second clamping arm 223 to rotate, thereby driving the magnetic core 10 to rotate.

[0075] The clamp 200 can stably clamp the magnetic core 10, and the clamp 200 can stably carry the magnetic core 10 to rotate, preventing the magnetic core 10 from falling and reducing the vibration and deviation of the magnetic core 10. The magnetic core 10 rotates around the same rotation center line as much as possible, which can ensure the winding quality and winding efficiency of the magnetic core 10.

[0076] It can be understood that one end of the first clamping arm 222 and one end of the second clamping arm 223 respectively abut two opposite sides of the magnetic core 10. When one end of the first clamping arm 222 and one end of the second clamping arm 223 clamp the magnetic core 10, the position of the magnetic core 10 is on the extension line of the rotation center line of the rotating shaft 210, and the central axis of the magnetic core 10 is coaxial with the rotation center line of the rotating shaft 210, so that the magnetic core 10 can rotate around its own central axis, thereby improving the rotation stability of the magnetic core 10.

[0077] A limiting surface is provided on one end of the first clamping arm 222 and / or one end of the second clamping arm 223. The limiting surface is perpendicular to the rotation center line of the rotating shaft 210, and the limiting surface faces the front of the first clamping arm 222 and the second clamping arm 223. The end face of one end of the magnetic core 10 can abut against the limiting surface, thereby realizing the limitation of the relative position between the magnetic core 10 and the first clamping arm 222 and / or the second clamping arm 223, that is, limiting the depth or distance of the magnetic core 10 extending into the first clamping arm 222 and the second clamping arm 223, to ensure that all the magnetic cores 10 clamped by the clamp 200 are in the same clamping position.

[0078] Reference Figure 4 and Figure 5 In some embodiments, the first clamping arm 222, the support plate 212 and the first adapter plate 211 are connected in sequence, the first clamping arm 222 is a fixed arm, the middle part of the second clamping arm 223 is hinged to the support plate 212, and the second clamping arm 223 is a movable arm. One end of the first clamping arm 222 and one end of the second clamping arm 223 are used to clamp one end of the magnetic core 10. The magnetic core 10 can be clamped or released by driving the second clamping arm 223 to rotate.

[0079] One end of the first elastic member 221 abuts or connects with the other end of the second clamping arm 223, and the other end of the first elastic member 221 abuts or connects with the support plate 212 or the first adapter plate 211. In a natural state, the first elastic member 221 forces one end of the second clamping arm 223 to swing toward one end of the first clamping arm 222, and one end of the second clamping arm 223 is in a state close to one end of the first clamping arm 222, so that one end of the first clamping arm 222 and one end of the second clamping arm 223 are in a closed state. That is, in a natural state, when no external force acts on the second clamping arm 223, one end of the first clamping arm 222 and one end of the second clamping arm 223 can always be in a state of clamping one end of the magnetic core 10.

[0080] It is understood that the clamp 200 also includes a pressure plate. The pressure plate, support plate 212, first clamping arm 222, second clamping arm 223, and first adapter plate 211 are all parallel to each other. The pressure plate is connected to the first adapter plate 211 via a first fastener. The pressure plate presses the first clamping arm 222 and support plate 212 against the first adapter plate 211. The middle portion of the second clamping arm 223 is hinged to the pressure plate and the first adapter plate 211 via a hinge. The first elastic member 221 is a first spring. The other end of the second clamping arm 223 is provided with a first limit block. The support plate 212 or the first adapter plate 211 is provided with a second limit block. The two ends of the first elastic member 221 are respectively sleeved on the first limit block and the second limit block. The first limit block and the second limit block serve to support and limit the first elastic member 221.

[0081] Reference Figure 4 and Figure 5 In some embodiments, the rear wire-management post 240 is provided on the first adapter plate 211, and the rear wire-management post 240 and the first adapter plate 211 are perpendicular to each other. The rear wire-management post 240 is used for allowing the wire to be wound around to position the wire and achieve the function of wire management. According to the requirements of winding the chip-type electronic components, the wire can be wound around the rear wire-management post 240 at different positions, and finally the wire can be wound around different positions of the magnetic core 10.

[0082] The fixture 200 also includes a sub-shaft 290 provided on the turntable 110, and the sub-shaft 290 is provided in front of the rotating shaft 210. The sub-shaft 290 and the rotating shaft 210 are coaxially arranged. The sub-shaft 290 and the rotating shaft 210 are both transmission-connected to the adapter shaft 270. The sub-shaft 290 and the rotating shaft 210 rotate synchronously. A second adapter plate 291 is provided on the sub-shaft 290. The axial direction of the sub-shaft 290 is parallel to the second adapter plate 291. Multiple front wire-management posts 230 are provided on the second adapter plate 291. The front wire-management posts 230 and the second adapter plate 291 are perpendicular to each other. The front wire-management posts 230 are used for wires to be wound around, so as to position the wires and realize the function of wire management. According to the requirements of winding the chip-type electronic components, the wires can be wound around the front wire-management posts 230 at different positions, and finally the wires can be wound around different positions of the magnetic core 10.

[0083] The rotating shaft 210 can carry the first adapter plate 211 to rotate, and the sub-shaft 290 can carry the second adapter plate 291 to rotate. The rotating shaft 210, the sub-shaft 290, the first adapter plate 211 and the second adapter plate 291 rotate synchronously. With the cooperation of the rear wiring post 240 and the front wiring post 230, the required winding can be wound on the magnetic core 10.

[0084] It is understandable that a plurality of mounting holes are provided on the pressure plate, and a plurality of rear cable management posts 240 are inserted into the mounting holes by means of interference fit or transition fit, and the plurality of rear cable management posts 240 are located behind the first clamping arm 222 and the second clamping arm 223. A plurality of front cable management posts 230 are connected to the second adapter plate 291 through the mounting plate. The mounting plate and the second adapter plate 291 are parallel to each other, and the plurality of front cable management posts 230 are perpendicular to the second adapter plate 291. A first oblong hole is provided on the mounting plate, and the length direction of the first oblong hole is perpendicular to the central rotation line of the split shaft 290. A second fastener is inserted into the first oblong hole, and the second fastener is threadedly connected to the second adapter plate 291. The second fastener fixes the mounting plate to the second adapter plate 291. When the second fastener is loosened, the position of the mounting plate on the second adapter plate 291 can be adjusted, thereby adjusting the positions of the plurality of front cable management posts 230 relative to the first clamping arm 222 and the second clamping arm 223, thereby enabling different windings to be wound around the magnetic core 10. In this embodiment, there are three front cable management posts 230 and four rear cable management posts 240.

[0085] Reference Figure 4and Figure 5 In some embodiments, the clamp 200 further includes a horizontally arranged lifting plate 281, which can be lifted and lowered on the turntable 110, and the top block 280 is connected to the lifting plate 281. When the lifting plate 281 carries the top block 280 to rise, the upper surface of the lifting plate 281 abuts against the lower surface of the first adapter plate 211 and the second adapter plate 291, so that the first adapter plate 211, the second adapter plate 291, the top block 280 and the first clamping arm 222 and The second clamping arm 223 remains horizontal, and the magnetic core 10 clamped by the first clamping arm 222 and the second clamping arm 223 will also remain horizontal. When the lifting plate 281 carrying the top block 280 descends, the lifting plate 281 and the top block 280 move away from the first adapter plate 211, the second adapter plate 291, the first clamping arm 222 and the second clamping arm 223, so that the first adapter plate 211, the second adapter plate 291, the first clamping arm 222 and the second clamping arm 223 can rotate.

[0086] Reference Figure 5 The winding machine also includes a second elastic member 282, which forces the lifting plate 281 to move upward, so that the lifting plate 281 and the top block 280 remain in a high position. The lifting plate 281 keeps the first adapter plate 211, the second adapter plate 291, the top block 280 and the first clamping arm 222 and the second clamping arm 223 horizontal, that is, in a natural state, the top block 280 is at the other end of the supporting magnetic core 10, and the first adapter plate 211, the second adapter plate 291, the top block 280 and the first clamping arm 222 and the second clamping arm 223 remain horizontal.

[0087] When it is necessary to wind the magnetic core 10, the fourth lifting drive mechanism is used to drive the lifting plate 281 downward so that the lifting plate 281 and the top block 280 remain in a low position, thereby preventing the lifting plate 281 and the top block 280 from interfering with the rotation of the first adapter plate 211, the second adapter plate 291, the first clamping arm 222 and the second clamping arm 223.

[0088] In some embodiments, the lifting plate 281 is connected to the turntable 110 via a sliding mechanism, and the sliding mechanism serves to guide the lifting plate 281 to rise and fall on the turntable 110 .

[0089] The sliding mechanism includes a sliding rail and a slider that cooperate with each other. The sliding rail is vertically arranged on the turntable 110. The slider is connected to the lifting plate 281. The lifting plate 281 is provided with a limiting rod. The second elastic member 282 is a spring. The second elastic member 282 is sleeved on the limiting rod. The two ends of the second elastic member 282 are respectively against the slider and the turntable 110. The limiting rod plays a role in supporting and limiting the second elastic member 282.

[0090] In some embodiments, the lifting plate 281 is connected to the top block 280 via an adjustment structure, and the adjustment structure is used to adjust the height position of the top block 280 on the lifting plate 281.

[0091] It can be understood that the adjustment structure includes a third fastener and a second oblong hole provided on the lifting plate 281. The length direction of the second oblong hole is the up and down direction. The third fastener is passed through the second oblong hole. The third fastener is threadedly connected to the top block 280. When the third fastener is tightened, the third fastener fixes the top block 280 on the lifting plate 281. When the third fastener is loosened, the position of the top block 280 on the lifting plate 281 can be adjusted. That is, the setting of the second oblong hole and the third fastener plays a role in adjusting the height of the top block 280 on the lifting plate 281.

[0092] According to the specific size of the magnetic core 10, the height of the top block 280 is adjusted so that when the two ends of the magnetic core 10 are placed across the support plate 212 and the top block 280, the magnetic core 10 can remain horizontal, so that when the magnetic core 10 is subsequently driven to rotate to achieve winding, the magnetic core 10 can rotate around the horizontal rotation center line.

[0093] Reference Figure 3 and Figure 5 In some embodiments, the adapter shaft 270 is arranged in the area below the rotating shaft 210 and the sub-shaft 290, and the adapter shaft 270 is away from the rotating shaft 210 and the sub-shaft 290 to avoid interference between the adapter shaft 270 and the rotating shaft 210, the sub-shaft 290, the first adapter plate 211, the second adapter plate 291, the support plate 212, the first clamping arm 222 and the second clamping arm 223.

[0094] It can be understood that the rotating shaft 210 and the split shaft 290 are respectively provided with a first pulley and a second pulley, the adapter shaft 270 is provided with a third pulley and a fourth pulley, the first pulley and the third pulley are wound with a first belt, and the second pulley and the fourth pulley are wound with a second belt.

[0095] In some embodiments, the rear thread clamp 260 is located on the first adapter plate 211, and the front thread clamp 250 is located on the second adapter plate 291. The rear thread clamp 260 and the front thread clamp 250 have the same structure. In their natural state, the rear thread clamp 260 and the front thread clamp 250 both remain in a clamped state, that is, they can maintain a state of clamping the wire. The turntable 110 also has the same structural rear and front opening clamp mechanisms, which are used to open the rear thread clamp 260 and the front thread clamp 250, respectively.

[0096] The first clamping mechanism 120 includes a third lifting drive mechanism disposed on the turntable 110 and a shift plate disposed at the output end of the third lifting drive mechanism. The third lifting drive mechanism drives the shift plate to move up and down. The shift plate has an inclined surface. When the inclined surface abuts against the first clamping arm 222, the first clamping arm 222 is driven to rotate, thereby opening the first clamping arm 222 and the second clamping arm 223. The first clamping mechanism 120 and the second clamping mechanism have the same or similar structures.

[0097] It is understandable that the first scissors and the second scissors are both electric scissors. The first jaw and the second jaw can be electric jaws or pneumatic jaws. Of course, the first jaw and the second jaw can also be replaced by a suction nozzle. The first lifting drive mechanism and the second lifting drive mechanism can both be cylinders. The first linear drive mechanism 410 and the second linear drive mechanism can both be cylinders. The structures of the first drive mechanism, the second drive mechanism, the third drive mechanism, the fourth drive mechanism and the fifth drive mechanism are the same or similar, and no redundant introduction is made here. The front thread end clamp 250, the rear thread end clamp 260, the rear open wire clamp mechanism, the front open wire clamp mechanism, the first open clamp mechanism 120 and the second open clamp mechanism can also adopt common equipment on the market, and no redundant introduction is made here. The first rotation drive mechanism 400 and the second rotation drive mechanism can both be motors.

[0098] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
