Description

Technical Field

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

[0002] With the continuous development of technology, coils are being used more and more widely. In the production process of integrated ignition coils, such as capacitive or inductive coils, copper wire needs to be wound onto a spool. To improve winding efficiency, a coil winding device is required to wind the copper wire.

[0003] A Chinese patent application with publication number CN 118711982 A discloses a coil winding device for electronic transformer production, relating to the field of transformer technology. The device includes a base plate with a support plate fixedly connected to the top. An electric telescopic rod is fixedly connected to one end of the support rod facing push block A. The right side of the electric telescopic rod is fixedly connected to the outer wall of the support plate. Push block B is rotatably connected to the electric telescopic rod. By setting a clamping mechanism, a stable clamping of the coil is maintained. Even if there is loosening between push block A and push block B, the spring force of spring A will push the pressure plate forward, maintaining the pressure of the pressure plate on the coil. Furthermore, workers can quickly determine whether the clamping has loosened by observing whether the pressure plate is in a vertical or tilted state, and whether it needs to be stopped and re-stabilized. This avoids the clamping instability problem that occurs when using a moderate clamping force instead of excessive clamping force to prevent coil deformation.

[0004] Existing winding devices cannot automatically adjust the tension of the copper wire during the winding process, resulting in the copper wire becoming too loose and poor adjustability of the copper wire tension. Therefore, a new coil winding device is proposed to address the above problem. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a coil winding device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a coil winding device, including a base, a control panel mounted on the base, a lifting plate mounted on the base, a lifting groove formed inside the lifting plate, a first stepper motor mounted on the lifting plate via a base, a first lead screw mounted on the output shaft of the first stepper motor, the first lead screw being rotatably mounted on the inner wall of the lifting groove, a lifting block assembled in the lifting groove, an adjusting block mounted on the lifting block, an indicator light mounted on the side wall of the adjusting block, a moving groove formed inside the adjusting block, a moving block assembled in the moving groove, and a first electrode mounted on the bottom side of the moving block. The moving slot has a second electrode plate installed on its inner wall. The first and second electrode plates are connected to the control panel via an internal circuit. An adjusting wheel is rotatably mounted on the moving block. A first guide tube and a second guide tube are fixedly mounted on the base. Copper wires pass through the first and second guide tubes. When the copper wire becomes too loose, the lifting block drives the adjusting wheel to move vertically downwards. The adjusting wheel continuously presses down on the copper wire. When the copper wire is taut, it lifts the adjusting wheel again. The control panel then stops the first stepper motor, thus achieving automatic adjustment of the copper wire tension and improving its adjustability.

[0007] Preferably, a release frame is mounted on the base, a first motor is mounted on the release frame via a base, a release roller is mounted on the output shaft of the first motor, and a wire spool is mounted on the release roller. A fixing frame is mounted on the base, a second motor is mounted on the fixing frame via a base, a rotating block is mounted on the output shaft of the second motor, and the rotating block is rotatably mounted on the fixing frame. A first sliding groove is formed inside the rotating block, and a second lead screw is rotatably mounted on the inner wall of the first sliding groove. The threads on the second lead screw are symmetrically opposite in direction, and a knob is mounted on one end of the second lead screw. Two sets of first sliders are symmetrically assembled in the first sliding groove, and positioning rods are mounted on the first sliders. A third lead screw is fixedly mounted on the rotating block, and the two sets of positioning rods are surrounded by... A winding drum is placed on the device. A limiting block is threaded onto the third lead screw. A guide plate is installed on the base. A second sliding groove is opened in the guide plate. A second stepper motor is installed on the side wall of the guide plate via a machine base. A fourth lead screw is installed on the output shaft of the second stepper motor. The fourth lead screw is rotatably mounted on the inner wall of the second sliding groove. A second slider is assembled in the second sliding groove. A sliding frame is installed on the second slider. A third guide tube is installed on the sliding frame. By rotating the release roller, the wire coil on it releases the copper wire. At the same time, two sets of positioning rods drive the winding drum held on them to rotate, and the winding drum winds up the copper wire. Meanwhile, the third guide tube pulls the copper wire to move horizontally back and forth, realizing uniform winding of the coil and improving the winding efficiency of the coil.

[0008] The advantages of this utility model are:

[0009] 1. This utility model achieves automatic adjustment of copper wire tension by using a lifting block to move the adjusting wheel vertically downward when the copper wire is too loose. The adjusting wheel continuously presses down on the copper wire. When the copper wire is taut, it lifts the adjusting wheel again, and the control panel stops the first step motor. This improves the adjustability of copper wire tension.

[0010] 2. This utility model uses a release roller to release copper wire by rotating it, while two sets of positioning rods drive the drum held on them to rotate, and the drum winds up the copper wire. At the same time, the third guide tube pulls the copper wire to move horizontally back and forth, which realizes uniform winding of the coil and helps to improve the winding efficiency of the coil.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-3 As shown, a coil winding device includes a base 1, a control panel 2 mounted on the base 1, a lifting plate 3 mounted on the base 1, a lifting groove 4 formed inside the lifting plate 3, a first stepper motor 5 mounted on the lifting plate 3 via a base, a first lead screw 6 mounted on the output shaft of the first stepper motor 5, the first lead screw 6 being rotatably mounted on the inner wall of the lifting groove 4, a lifting block 35 assembled inside the lifting groove 4, an adjusting block 36 mounted on the lifting block 35, an indicator light 7 mounted on the side wall of the adjusting block 36, a moving groove 8 formed inside the adjusting block 36, a moving block 9 assembled inside the moving groove 8, a first electrode plate 10 mounted on the bottom side of the moving block 9, and a second electrode plate 11 mounted on the inner wall of the moving groove 8. The first electrode plate 10 and the second electrode plate 11... The plate 11 is connected to the control panel 2 through an internal circuit. An adjusting wheel 12 is rotatably mounted on the moving block 9. A first guide tube 13 and a second guide tube 14 are fixedly mounted on the base 1. A copper wire 15 passes through the first guide tube 13 and the second guide tube 14. During operation, the existing winding device cannot automatically adjust the tension of the copper wire 15 during the winding process, resulting in the copper wire 15 being too loose. This leads to poor adjustability of the tension of the copper wire 15. The first motor 37 operates, driving the release roller 17 to rotate, and the coil on it releases the copper wire 15. At the same time, the second motor 19 operates, driving the drum 26 to rotate, and the drum 26 winds up the copper wire 15, thus realizing the winding of the coil.

[0020] During this process, the copper wire 15 passes sequentially through the first guide tube 13, the second guide tube 14, and the third guide tube 34. The copper wire 15 between the first guide tube 13 and the second guide tube 14 is taut, at which point it lifts the adjusting wheel 12. The adjusting wheel 12, along with the moving block 9, is suspended in the moving groove 8. At this time, the first electrode plate 10 and the second electrode plate 11 are not in contact. When the copper wire 15 becomes too loose, it will fall downwards. At this point, the copper wire 15 no longer lifts the adjusting wheel 12, and the adjusting wheel 12 moves vertically downwards under its own weight. The adjusting wheel 12 drives the moving block 9 to move vertically downwards within the moving groove 8. The first electrode plate 11 on the bottom side of the moving block 9... The first electrode 10 will come into contact with the second electrode 11, causing the indicator light 7 to be internally connected. The indicator light 7 sends an electrical signal to the control panel 2. The control panel 2 controls the first stepper motor 5 to operate. The first stepper motor 5 drives the first lead screw 6 to rotate. The first lead screw 6 drives the lifting block 35 on it to move vertically downward. The lifting block 35 drives the adjusting wheel 12 on it to move vertically downward. During the descent of the adjusting wheel 12, it will continuously press down on the copper wire 15. When the copper wire 15 is in a taut state, the copper wire 15 will lift the adjusting wheel 12 again, causing the first electrode 10 and the second electrode 11 to separate. The control panel 2 controls the first stepper motor 5 to stop operating, realizing the automatic adjustment of the tension of the copper wire 15, which is beneficial to improving the adjustability of the tension of the copper wire 15.

[0021] Please see Figure 4-5As shown, a release frame 16 is mounted on the base 1. A first motor 37 is mounted on the release frame 16 via a base. A release roller 17 is mounted on the output shaft of the first motor 37, and a wire spool is mounted on the release roller 17. A fixing frame 18 is mounted on the base 1. A second motor 19 is mounted on the fixing frame 18 via a base. A rotating block 20 is mounted on the output shaft of the second motor 19. The rotating block 20 is rotatably mounted on the fixing frame 18. A first sliding groove 21 is formed inside the rotating block 20. A second lead screw 22 is rotatably mounted on the inner wall of the first slide groove 21. The threads on the second lead screw 22 are symmetrically opposite in direction. A knob 23 is installed at one end of the second lead screw 22. Two sets of first sliders 24 are symmetrically assembled in the first slide groove 21. Positioning rods 25 are installed on the first sliders 24. A third lead screw 38 is fixedly mounted on the rotating block 20. A drum 26 is placed around the two sets of positioning rods 25. A limit block 27 is threaded onto the third lead screw 38. A guide plate 28 is installed on the base 1. The device has a second slide groove 29 inside. A second stepper motor 30 is mounted on the side wall of the guide plate 28 via a base. A fourth lead screw 31 is mounted on the output shaft of the second stepper motor 30. The fourth lead screw 31 is rotatably mounted on the inner wall of the second slide groove 29. A second slider 32 is assembled inside the second slide groove 29. A sliding frame 33 is mounted on the second slider 32. A third guide tube 34 is mounted on the sliding frame 33. During operation, the existing winding device has low winding efficiency because it cannot wind the coil efficiently. By placing the drum 26 around the two sets of positioning rods 25, and then rotating the knob 23 to drive the second lead screw 22 to rotate, the second lead screw 22 drives the two sets of first sliders 24 on it to move synchronously in opposite directions. The two sets of first sliders 24 drive the two sets of positioning rods 25 to move synchronously in opposite directions. The two sets of positioning rods 25 clamp and fix the drum 26. Then, the limiting block 27 is screwed onto the third lead screw 38 to achieve secondary limiting of the drum 26.

[0022] Then, the first motor 37 operates, driving the release roller 17 to rotate, releasing the copper wire 15 from the coil on it. At the same time, the second motor 19 operates, driving the rotating block 20 to rotate. The rotating block 20 drives the two sets of positioning rods 25 to rotate, and the two sets of positioning rods 25 drive the drum 26 clamped on them to rotate. The drum 26 winds up the copper wire 15. Simultaneously, the second stepper motor 30 operates, driving the fourth lead screw 31 to rotate. The fourth lead screw 31 drives the second slider 32 on it to move horizontally back and forth. The second slider 32 drives the sliding frame 33 to move horizontally back and forth. The sliding frame 33 drives the third guide tube 34 to move horizontally back and forth. The third guide tube 34 pulls the copper wire 15 to move horizontally back and forth, realizing uniform winding of the coil and improving the winding efficiency of the coil.

[0023] Working principle: In existing winding devices, the tension of the copper wire 15 cannot be automatically adjusted during the winding process, resulting in the copper wire 15 becoming too loose and poor tension adjustability. The first motor 37 operates, driving the release roller 17 to rotate, releasing the copper wire 15. Simultaneously, the second motor 19 operates, driving the drum 26 to rotate, winding the copper wire 15, thus achieving coil winding. During this process, the copper wire 15 sequentially passes through the first guide tube 13, the second guide tube 14, and the third guide tube 34. The first guide tube 13 and the second guide tube 34... When the copper wire 15 between the first guide tube 13 and the second guide tube 14 is taut, it lifts the adjusting wheel 12, which, along with the moving block 9, is suspended in the moving groove 8. At this time, the first electrode plate 10 and the second electrode plate 11 are not in contact. If the copper wire 15 becomes too loose, it will fall downwards. In this case, the copper wire 15 will no longer lift the adjusting wheel 12, and the adjusting wheel 12 will move vertically downwards under its own weight. The adjusting wheel 12 will then drive the moving block 9 to move vertically downwards in the moving groove 8. The first electrode plate 10 on the bottom side of the moving block 9 will then come into contact with the second electrode plate 11, causing the indicator... When the internal circuit of lamp 7 is activated, indicator light 7 sends an electrical signal to control panel 2. Control panel 2 controls the operation of the first stepper motor 5, which drives the first lead screw 6 to rotate. The first lead screw 6 drives the lifting block 35 on it to move vertically downward. The lifting block 35 drives the adjusting wheel 12 on it to move vertically downward. During the descent of the adjusting wheel 12, it continuously presses down on the copper wire 15. When the copper wire 15 is in a taut state, it will push the adjusting wheel 12 up again, causing the first electrode plate 10 and the second electrode plate 11 to separate. Control panel 2 then controls the first stepper motor 5 to stop operating, thus realizing the automatic adjustment of the tension of the copper wire 15. This section helps improve the adjustability of the copper wire 15 tension. Existing winding devices have low winding efficiency because they cannot wind the coil efficiently. By placing the drum 26 around the two sets of positioning rods 25, and then rotating the knob 23 to drive the second lead screw 22 to rotate, the second lead screw 22 drives the two sets of first sliders 24 on it to move synchronously in opposite directions. The two sets of first sliders 24 drive the two sets of positioning rods 25 to move synchronously in opposite directions. The two sets of positioning rods 25 clamp and fix the drum 26. Then, the limiting block 27 is screwed onto the third lead screw 38 to achieve secondary limiting of the drum 26.Then, the first motor 37 operates, driving the release roller 17 to rotate, releasing the copper wire 15 from the coil on it. Simultaneously, the second motor 19 operates, driving the rotating block 20 to rotate. The rotating block 20 drives the two sets of positioning rods 25 to rotate, which in turn drives the drum 26 clamped on them to rotate, winding the copper wire 15. At the same time, the second stepper motor 30 operates, driving the fourth lead screw 31 to rotate. The fourth lead screw 31 drives the second slider 32 on it to move horizontally back and forth. The second slider 32 drives the sliding frame 33 to move horizontally back and forth, which in turn drives the third guide tube 34 to move horizontally back and forth. The third guide tube 34 pulls the copper wire 15 to move horizontally back and forth, achieving uniform winding of the coil and improving the winding efficiency.
