Description

Technical Field

[0001] The invention relates to the field of coil winding, and more particularly to a split-petal hollow coil winding device. Background Art

[0002] A hollow coil is an electromagnetic component made of a wire wound into one or more circles. The hollow coil is wound with an insulated wire, which is usually an insulated copper wire or aluminum wire. The diameter and number of turns of the wire can be determined according to the specific application requirements. The shape of the hollow coil can be different shapes such as round and square, and it can be selected according to the specific application. The split hollow coil is a special type of hollow coil, which consists of multiple separated wire petals, each of which is in the shape of an arc and arranged in a certain geometric structure to form a hollow ring. This design allows gaps between the wire petals of the hollow coil, making the magnetic field more penetrating.

[0003] In the laboratory, since there is no specific equipment to produce the hollow coils they need, the needs of laboratory personnel are usually met by manual winding methods, which will produce large errors, resulting in performance deviations of homemade electronic devices or related experimental results.

[0004] Under the influence of this factor, Chinese patent CN116344202A specifically discloses a hollow coil winding mechanism and winding method, which fixes one end of the coil by turning the screw to make the clamping block, and then drives the winding jig to rotate through the motor, and cooperates with the lead screw to drive the winding jig to move to achieve the winding work, thereby reducing the burden of manual winding, making the work stable and improving the accuracy.

[0005] Although this prior art reduces the burden of manual winding and improves efficiency, during the wire winding process, since the winding drum to be wound is hung on a hook, the wire on the winding drum has no tension during the process of the winding jig rotating to wind the wire to form a coil. This will cause the wire to be wound loosely and not tightly enough during the winding process. This will cause the coil to become loose and deformed as a whole, thereby affecting the stability and mechanical strength of the coil, and further causing the electrical performance and working effect of the final coil to deteriorate. Summary of the invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a split-petal hollow coil winding device, which can increase the tension of the wire during the process of winding the wire to form a hollow coil, thereby avoiding the situation where the wire is not wound tightly enough and thus becomes loose, and can effectively improve the tightness of the wire and facilitate the shape of the formed coil, thereby effectively improving the stability and mechanical strength of the final coil.

[0035] See also Figures 1 to 8 A split-flap hollow coil winding device comprises a workbench 1, a top seat 2 is fixedly installed on the top of the workbench 1,

[0036] Also includes:

[0037] The winding assembly includes an electric telescopic rod 3 fixedly mounted on the top seat 2, a mounting frame 4 fixedly mounted on the output end of the electric telescopic rod 3, the mounting frame 4 is slidably connected to the top seat 2, a motor 5 is fixedly mounted inside the mounting frame 4, a winding roller 6 is rotatably mounted on the bottom of the mounting frame 4, the winding roller 6 is fixedly connected to the output shaft of the motor 5, a fixing groove 7 is provided on one side of the winding roller 6, a splint 8 is slidably mounted on the inner wall of the fixing groove 7, a threaded rod 9 is threadedly connected to the bottom of the winding roller 6, the top of the threaded rod 9 is rotatably connected to the splint 8, and a tightening assembly is provided on one side of the winding roller 6.

[0038] The tightening assembly includes two groups of support plates 10 fixedly installed on the top of the workbench 1, a winding drum 11 is rotatably installed between the two groups of support plates 10, one end of the winding drum 11 is fixedly connected to a conical rod 24, the conical rod 24 is rotatably connected to the adjacent support plate 10, a connecting rope 25 is fixedly connected to the conical rod 24, a placement plate 31 is arranged below the conical rod 24, a gravity ball 28 is in contact with the top of the placement plate 31, a connecting rope 27 is fixedly installed on the top of the gravity ball 28, a rotating block 26 is fixedly installed on the opposite end of the connecting rope 27 and the connecting rope 1 25, the two groups of rotating blocks 26 are rotatably connected, a connecting plate 29 is fixedly installed on the support plate 10 close to the conical rod 24 side, an elastic rod 30 is fixedly installed on one side of the connecting plate 29, and the other end of the elastic rod 30 is fixedly connected to the gravity ball 28.

[0039] First, pull one end of the wire wound on the winding drum 11 and insert it into the inner cavity of the fixed groove 7, then rotate the threaded rod 9, the threaded rod 9 rotates and drives the clamping plate 8 to move upward, so that the clamping plate 8 can move upward to fix one end of the wire on the winding drum 11 in the inner cavity of the fixed groove 7, and then turn on the motor 5, the output end of the motor 5 will drive the winding roller 6 to rotate, and at the same time turn on the electric telescopic rod 3, the extension of the output end of the electric telescopic rod 3 will drive the installation frame 4 to move downward, and the installation frame 4 will drive the winding roller 6 to move synchronously while moving downward, at this time, the cooperation between the motor 5 and the electric telescopic rod 3 can make the winding The control roller 6 rotates and moves downward at the same time, and at this time, the winding roller 6 can evenly wind the wire on the winding drum 11 to form a coil. When the winding roller 6 winds the wire on the winding drum 11, the wire will pull the winding drum 11 to rotate. When the winding drum 11 rotates, it will drive the conical rod 24 to rotate, and the conical rod 24 will drive the connecting rope 1 25 to rotate, so that the connecting rope 1 25 can be wound on the inclined surface of the conical rod 24. When the connecting rope 1 25 is wound by the conical rod 24, it will drive the connecting rope 2 27 to move upward through the two sets of rotating blocks 26. The upward movement of the connecting rope 2 27 will bring The dynamic gravity ball 28 moves upward away from the top of the placement plate 31. At the same time, the upward movement of the gravity ball 28 squeezes the elastic rod 1 30 and causes the elastic rod 1 30 to be elastically bent. The outer wall of the tapered rod 24 is set as an arc surface, and the connecting rope 1 25 and the connecting rope 2 27 are connected to form an oblique setting. Under the elastic force of the elastic rod 1 30, the tapered rod 24 can be rotated to drive the connecting rope 1 25 to be wound on it for less than one circle. The connecting rope 1 25 will slide off on the inclined surface of the tapered rod 24. When the connecting rope 1 25 slides off from the tapered rod 24, under the force of the elastic rod 1 30, When the elastic rod 1 30 returns to its initial state, it will drive the connecting rope 2 27 and the connecting rope 1 25 to immediately return to the straightened state through the gravity ball 28. Through the cooperation of the gravity of the gravity ball 28 and the elastic force of the elastic rod 1 30, when the wire is wound on the outer wall of the winding roller 6 and the winding drum 11 is pulled to rotate, the winding drum 11 will continue to apply tension to the wire, thereby increasing the tension on the wire, avoiding the situation where the wire is not wound tightly enough and thus becomes loose, effectively improving the tightness of the wire and facilitating the guarantee of the shape of the formed coil, thereby effectively improving the stability and mechanical strength of the final coil;

[0040] By setting the two sets of rotating blocks 26 to rotate, it can be achieved that when the connecting rope 25 is wound on and falls off the tapered rod 24, the connecting rope 25 itself will not be twisted together, and it can be achieved that it can automatically rotate through the rotating block 26 to restore the initial state.

[0041] like Figures 1 to 7As shown, a push plate 12 is provided on the outer side of the winding roller 6, and a T-shaped plate 15 is slidably installed on the top of the push plate 12 close to the winding drum 11, and a telescopic spring 16 is fixedly installed between the T-shaped plate 15 and the push plate 12, and the top end of the T-shaped plate 15 is fixedly connected to the top seat 2.

[0042] A second elastic rod 17 is fixedly mounted on one side of the bottom of the push plate 12 close to the winding drum 11, a U-shaped block 18 is fixedly mounted on the bottom end of the second elastic rod 17, and a ball 19 is evenly and rollingly mounted in the inner cavity of the U-shaped block 18.

[0043] Before inserting the wire on the winding drum 11 into the fixed groove 7, first insert one end of the wire from the inner cavity of the U-shaped block 18, and move the wire body of the wire between each group of balls 19, and then pull one end of the wire into the fixed groove 7 and clamp it with the clamping plate 8. At this time, the wire body of the wire can form an obtuse angle between the fixed groove 7, the U-shaped block 18 and the top of the winding drum 11. The elastic force setting of the elastic rod 17 will cause the U-shaped block 18 to press the wire body of the wire downward, which can effectively increase the tension of the wire and prevent the wire from loosening during winding on the outer wall of the winding roller 6, so that The electrical performance and working effect of the final coil are effectively improved. Through the arrangement of each group of balls 19, it is possible to apply pressure to the wire and facilitate the conveying of the wire, thereby avoiding the wear of the wire during the conveying process, thereby effectively ensuring the quality of the wire itself. At the same time, through the arrangement of the U-shaped block 18, it is possible to avoid the wire sliding and deflecting on the outer wall of the winding roller 6 during the winding process of the wire by the winding roller 6, thereby effectively improving the uniformity of the winding, and avoiding the uneven current density distribution inside the coil caused by uneven winding of the wire during use, thereby balancing the overall heat and load of the coil.

[0044] When the electric telescopic rod 3 drives the winding roller 6 to move downward through the mounting frame 4, when the mounting frame 4 contacts the top of the push plate 12, the mounting frame 4 continues to move downward to push the push plate 12 to move downward and stretch the telescopic spring 16. The setting of the telescopic spring 16 can avoid the situation where the mounting frame 4 drives the winding roller 6 to move downward and is blocked. In this process, since each group of balls 19 has contacted the outer wall of the wire body of the conductor, the push plate 12 will apply pressure to the elastic rod 17 while moving downward, so that the elastic rod 17 is squeezed and elastically bent. The elastic force of the elastic rod 17 being squeezed can realize that the U-shaped block 18 will apply pressure to the wire again, thereby effectively increasing the tension of the wire.

[0045] After the wire is wound on the outer wall of the winding roller 6 for a certain number of turns, the motor 5 is turned off and the wire is cut with a tool. Then the threaded rod 9 is rotated to drive the clamping plate 8 to move downward to cancel the clamping of the wire in the fixed groove 7, and then the bottom end of the wire is moved out of the fixed groove 7. Then the electric telescopic rod 3 is controlled to drive the winding roller 6 to move upward through the mounting frame 4. While the winding roller 6 moves upward, it will drive the coil wound on its outer wall to move synchronously. When the coil on the outer wall of the winding roller 6 contacts the bottom of the push plate 12, the winding roller 6 can continue to move upward, so that the wound coil is pushed off the outer wall of the winding roller 6 by the push plate 12. The staff can also manually remove the coil from the winding roller 6, which plays the role of automatic removal, saving time and effort, and effectively improving work efficiency.

[0046] like Figures 1 to 4 and Figure 6 As shown, U-shaped seats 20 are provided on both the front and rear sides of the winding roller 6, rotating rollers 21 are rotatably installed on the opposite sides of the two groups of U-shaped seats 20, fixed plates 22 are provided on the opposite sides of the two groups of U-shaped seats 20, the two groups of fixed plates 22 are fixedly connected to the top of the workbench 1, two groups of return springs 23 are fixedly installed between the two groups of fixed plates 22 and adjacent U-shaped seats 20, and the two groups of U-shaped seats 20 are slidably connected to the adjacent fixed plates 22 and the top of the workbench 1.

[0047] In the process of the winding roller 6 winding the wire into a coil, the winding roller 6 drives the wire to rotate and contact the two groups of rotating rollers 21, which can squeeze the rotating roller 21 to drive the U-shaped seat 20 to slide on the top of the workbench 1 to the side away from the winding roller 6. The rotating roller 21 squeezes the reset spring 23 thereon while moving. The winding roller 6 drives the wire on its outer wall to rotate and drives the two groups of rotating rollers 21 in contact with the wire to rotate synchronously. The elastic force of the reset spring 23 can be used to compact the wire wound on the outer wall of the winding roller 6 by the rotating roller 21, so that the wire can be tightly attached to the outer wall of the winding roller 6, which can effectively improve the tightness of the winding and avoid looseness, thereby effectively improving the mechanical strength of the final coil.

[0048] like Figures 1 to 3 and Figure 6 As shown, a through opening 14 is provided on the top of the workbench 1, and a special-shaped telescopic rod 33 is arranged in the through opening 14. A rotating plate 35 is fixedly installed on the top of the special-shaped telescopic rod 33 and the bottom of the threaded rod 9, and the two sets of rotating plates 35 are rotatably connected.

[0049] A base plate 13 is fixedly installed between each group of supporting legs at the bottom of the workbench 1, and a baffle 34 is slidably installed on one side of the top of the base plate 13. The baffle 34 contacts one end of the special-shaped telescopic rod 33, and the baffle 34 is fixedly connected to the special-shaped telescopic rod 33 by screws.

[0050] By setting the two sets of rotating plates 35, when the threaded rod 9 rotates, the rotating plate 35 on the upper side thereof will be driven to rotate synchronously. Since the rotating plate 35 on the upper side is rotatably connected with the rotating plate 35 on the lower side, the rotation of the threaded rod 9 will not be hindered. When the threaded rod 9 rotates upward, the two sets of rotating plates 35 will be driven upward to stretch the special-shaped telescopic rod 33. When the threaded rod 9 rotates downward, the two sets of rotating plates 35 will be driven downward to shrink the special-shaped telescopic rod 33. When the output end of the electric telescopic rod 3 shrinks and extends, the winding roller 6 will be driven up and down by the threaded rod 9. The special-shaped telescopic rod 33 is made to stretch and shrink adaptively. After the coil on the outer wall of the winding roller 6 is removed, it will slide onto the outer wall of the special-shaped telescopic rod 33 through the through hole 14, and slide along the special-shaped telescopic rod 33 to the bottom end of the special-shaped telescopic rod 33. The setting of the special-shaped telescopic rod 33 can store multiple coils. When the coil on the special-shaped telescopic rod 33 needs to be removed, the screws on the baffle 34 are removed, and the baffle 34 is moved away from the bottom end of the special-shaped telescopic rod 33, so that the coil on the special-shaped telescopic rod 33 can be removed, thereby making it easy to string the completed coils together, which can effectively improve the working effect.

[0051] like Figure 2 , Figure 3 and Figures 5 to 7 As shown, a fan 32 is disposed between the two groups of support plates 10 . The fan 32 is fixedly installed on the top of the workbench 1 , and the output end of the fan 32 is directly facing between the two groups of rotating rollers 21 .

[0052] The inner cavity of the U-shaped block 18 is flush with the fixed groove 7 and is lower than the top wall of the winding drum 11, so as to apply pressure to the wire on the winding drum 11. The distance between the two sets of rotating rollers 21 and the winding roller 6 is smaller than the width of the wire, so as to facilitate the two sets of rotating rollers 21 to compact the wire wound on the winding roller 6.

[0053] Three groups of balls 19 are provided, and the distances between the three groups of balls 19 are adapted to the conductors on the winding drum 11, so as to facilitate the conveyance of the conductors.

[0054] By turning on the fan 32, the output end of the fan 32 can blow air between the two groups of rotating rollers 21, and the hot air or cold air can be controlled according to demand. When the winding roller 6 is in the process of winding the wire into a hollow coil, when it moves downward through the output end of the fan 32, the output end of the fan 32 can blow air to the wire wound on the winding roller 6. The hot air or cold air can accelerate the drying process of the coil. For a wet coil, the moisture on its surface can be volatilized, and the drying of the inside of the coil can be accelerated, thereby improving the insulation performance of the coil.

[0055] Instructions for use: First, insert one end of the wire on the winding drum 11 into the fixed groove 7, and move the wire body into the U-shaped block 18 and place it between each group of balls 19. The elastic force of the elastic rod 2 17 can be used to apply pressure to the wire and prevent the wire from deviating during the winding process on the winding roller 6. Rotate the threaded rod 9 to clamp and fix it. Then, the motor 5 and the electric telescopic rod 3 can cooperate to drive the winding roller 6 to rotate and move downward. At this time, the wire on the winding drum 11 can be wound to form a hollow coil. During the rotation of the winding drum 11, the connecting rope 25 will be driven by the tapered rod 24 to be wound. The cooperation between the elastic force of the elastic rod 30 and the gravity of the placing plate 31 can realize applying tension to the wire on the winding drum 11 during the winding process on the winding roller 6. Through the cooperation of the rotating roller 21 and the reset spring 23, the wire wound on the winding roller 6 can be compacted on the surface of the winding roller 6. After the wire on the winding roller 6 is wound into the required coil, the wire is cut and the bottom end of the coil is moved out of the fixing groove 7. At this time, the completed coil on the winding roller 6 can be removed and strung on the special-shaped telescopic rod 33. By removing and moving away the baffle 34 from the bottom end of the special-shaped telescopic rod 33, the coil on the special-shaped telescopic rod 33 can be removed.

[0056] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
