Abstract
Description
Technical Field
[0001] The utility model relates to the field of micro motors, in particular to a winding binding mechanism for micro motors. Background Art
[0002] Conventional motor stator windings currently require white binding wire to secure the coils at both ends. This is typically done using automated equipment, which employs side puncture and top or bottom hooking. This requires the wire to swing within the coil, resulting in a large amplitude and difficulty in reducing it indefinitely. This makes it inoperable for coils with smaller inner diameters and unsuitable for micro motors. Current equipment is generally suitable for motors with inner diameters of 60mm or larger. For micro motors (with inner diameters under 30mm), manual binding is still used. This is costly, inefficient, and can cause significant fatigue to workers' fingers and arms. Existing automated equipment for conventional motors (with diameters greater than 30mm) is limited by size, making side puncture and top or bottom hooking difficult. Therefore, a new approach is needed. Utility Model Content
[0003] In view of this, the present invention needs to overcome at least one of the above-mentioned defects in the prior art.
[0004] The utility model provides a micro motor winding binding mechanism, comprising:
[0005] A micro motor stator coil is placed on a winding rotation positioning platform, a threading needle with a binding line installed and capable of shifting up and down and forward and backward, and a spiral thread hook shuttle that can shift up and down and rotate to form a binding line for binding and knotting with the threading needle;
[0006] The positioning platform includes a product concentric positioning support and a product clamp, the stator coil is arranged on the concentric positioning support, and the inner side of the product clamp clamps the stator coil; the threading needle is placed on the outside of the stator coil, and the front section of the threading needle has a binding wire avoidance gap and a threading hole for passing the binding wire; the spiral thread hooking shuttle is arranged above the hollow hole of the stator coil, and the spiral thread hooking shuttle has a three-dimensional smooth spiral rising surface, and the three-dimensional smooth spiral rising surface spirally rises from the front end with a cross-sectional angle changing from small to large, and has a front section that hooks the binding wire to form a wire loop and a rear section that further rotates after the wire loop is formed to make the binding wire fall off.
[0007] The process is to place the stator coil of the micro motor winding on the product concentric positioning support of the winding rotation positioning platform for positioning and fixing it, the winding rotation positioning platform rotates to the starting position angle or sets the stator coil at the starting position angle at the beginning, the threading needle with the input binding line starts from the starting position and penetrates from the hole on the stator coil, the rotating thread hooking shuttle moves down from the top, and uses the three-dimensional smooth spiral rising curved front section of the rotating thread hooking shuttle to rotate and hook the binding line through the binding line avoidance notch on the threading needle, and further rotates when the threading needle is withdrawn, and uses the three-dimensional smooth rotating rising curved surface to form a wire loop, when the threading needle withdraws from the stator coil, it moves up to the top of the stator coil synchronously with the rotating thread hooking shuttle, and penetrates the wire loop for the second time, and the rotating thread hooking shuttle continues to rotate and hooks the wire rope again, and the upper part during the rotation process When the wire loop falls off, the threading needle retreats, forming a knot on the stator coil. The threading needle and the rotating thread hook shuttle move down to their respective initial positions. The winding rotary positioning platform rotates synchronously and rotates to the next hole position. The threading needle, carrying the binding wire, re-enters the hole of the stator coil. The binding wire is hooked by the front section of the three-dimensional smooth spiral ascending curve and rotates to form a wire loop. The threading needle retreats, and the threading needle and the rotating thread hook shuttle simultaneously move up above the stator coil. The threading needle passes through the wire loop again and retreats. The rotating thread hook shuttle rotates synchronously and hooks the wire rope again. During the rotation, the previous wire loop falls off, forming a knot. The threading needle and the rotating thread hook shuttle move down back to their respective initial positions. This cycle repeats until the stator coil completes one rotation and the binding wire is tied. The binding wire can be cotton thread, polyester thread, carbon fiber thread, or other wire required for the coil.
[0008] The utility model discloses a micro motor winding binding mechanism, which can load coil materials to the product concentric positioning support of the winding rotation positioning platform through manual or automatic equipment, start the equipment CCD station to cooperate with the rotating tooling to detect and correct the coil starting position reaming station, and perform needle hole expansion on the coil. The rotating hook shuttle cooperates with the needle threading module multi-axis linkage to bind the coil in turn for one circle and then withdraw the needle. The hook and thread cutting mechanism pulls out the binding wire and clamps it to hold it, and the hook and thread cutting mechanism extends scissors to cut the binding wire.
[0009] In some embodiments, the cross-sectional angle of the front section of the three-dimensional smooth spiral rising curve is less than or equal to 40 degrees.
[0010] Preferably, the cross-sectional angle of the front section is less than 10 degrees.
[0011] In some embodiments, the angle of the front section of the three-dimensional smooth spiral rising curve gradually increases from a small angle to a larger angle, and the cross-sectional angle of the rear section of the three-dimensional smooth spiral rising curve is less than 80 degrees.
[0012] Preferably, the cross-sectional angle of the rear section of the three-dimensional smooth spiral ascending surface is less than 60 degrees.
[0013] The cross-section here can be a cross-section formed by the plane of the central axis of the rotating thread hooking shuttle and the rotating rising surface of the rotating thread hooking shuttle, or it can be a cross-section parallel to the starting surface of the front section of the rotating rising curve. The cross-section angle is the angle between the oblique line on this cross-section and the horizontal plane. The three-dimensional smooth spiral rising surface can be composed of a small cross-sectional angle in the front section gradually changing to a large cross-sectional angle in the rear section, and forming a spiral rising structure, or it can be a conical surface that gradually changes from a small cross-sectional angle to a large cross-sectional angle, that is, it is composed of a continuous conical surface with gradually changing angles, or it can be a spiral rising surface designed through experience. It needs to ensure that when the rotating thread hooking shuttle rotates to a first predetermined angle, the binding line does not fall off and forms a predetermined wire loop. When it rotates to a second predetermined angle, the needle is retracted and the binding line falls off to form a knot. The first predetermined angle and the second predetermined angle here need to be designed through experience, and there is no specific formula or theory to guide.
[0014] In some embodiments, the rotary thread hook shuttle is installed on a rotary thread hook shuttle motion mechanism, and the threading needle is installed on a threading motion mechanism. The rotary thread hook shuttle motion mechanism includes a rotary thread hook shuttle up and down displacement component for adjusting the up and down position of the rotary thread hook shuttle and a rotary thread hook shuttle rotating component for rotating the rotary thread hook shuttle. The threading needle motion mechanism includes a needle up and down displacement component for shifting the needle up and down and a needle forward and backward displacement component for the forward and backward threading action of the needle.
[0015] The present invention also provides a device based on a micro motor winding binding mechanism, including the above-mentioned micro motor winding binding mechanism:
[0016] In some embodiments, the device also includes a wire hooking and cutting mechanism, which includes a binding wire hook for hooking the binding wire, a wire clamping mechanism and a wire end cutting mechanism, and the binding wire hook is installed on the hook forward and backward movement mechanism.
[0017] In some embodiments, the hook forward and backward movement mechanism includes a hook forward and backward movement component and a hook slider installed on the hook forward and backward movement component, the hook is installed on the hook slider, the hook wire clamping structure includes a hook clamping component for clamping the binding line and a hook up and down movement component for moving up and down, and the wire cutting mechanism includes pneumatic scissors and a scissors telescopic component for installing the pneumatic scissors.
[0018] In some embodiments, the device further includes a CCD rotation correction mechanism, which includes an annular hollow light source, a telecentric lens arranged at the rear side of the annular hollow light source, and a camera arranged at the rear end of the telecentric lens.
[0019] In some embodiments, the device also includes a wire reverse tensioning mechanism, which includes a wire tensioning upper and lower shafts, a wire tensioning tension sensor, a wire tensioning brake cylinder, and a plurality of pulleys for bypassing the binding wire. The binding wire passes through the plurality of pulleys and the clamping mechanism of the wire tensioning brake cylinder and is connected to the feeding mechanism of the rear section. The clamping mechanism is a clamping block arranged at the front end of the wire tensioning brake cylinder. The clamping block may have a toothed structure. When clamped, the wire tensioning brake cylinder extends, and the clamping block is used to press the binding wire. The wire tensioning upper and lower shafts are pulled upward, so that the binding wire is tightened. At the same time, the tension of each knot is ensured to be consistent according to the feedback from the tension sensor.
[0020] The process is to tighten the wire in reverse. When the front needle retracts after tying a knot, the brake cylinder of the tensioning mechanism presses the wire feeding end, and the tensioning shaft rises to tighten the knot tied at the front end in reverse. The force during the tightening process is fed back by the tension sensor and the tension range is set to ensure that the tension of each knot is consistent. The rear wire tension feeding device ensures that the wire is continuously fed in a stable and tight state with the set tension torque.
[0021] The overall process of this case is: place the binding wire roll on the binding wire feeding mechanism, pass the binding wire through the tension mechanism, the binding wire reverse tensioning mechanism, and the needle movement mechanism in sequence, and finally pass through the needle to pierce the hole and set it on the needle. After the binding wire is set, place the micro motor coil on the winding rotation positioning mechanism, position it and fix it, adjust the position of the coil hole through the CCD rotation correction mechanism to achieve coil hole positioning, the winding rotation positioning platform rotates to the starting position angle or sets the stator coil at the starting position angle from the beginning, and the needle with the binding wire starts from the starting position and penetrates the hole on the stator coil. The rotating thread hooking shuttle moves down from the top, and uses the three-dimensional smooth spiral rising curved front section of the rotating thread hooking shuttle to rotate and hook the binding thread through the binding thread avoidance notch on the threading needle, and further rotates when the threading needle is withdrawn, and uses the three-dimensional smooth rotating rising curved surface to form a thread loop. When the threading needle is withdrawn from the stator coil, it moves up synchronously with the rotating thread hooking shuttle to above the stator coil, and inserts the thread loop for the second time and withdraws. At the same time, the rotating thread hooking shuttle continues to rotate and hooks the thread rope again. During the rotation, the upper thread loop falls off, forming a knot on the stator coil, and the threading needle and the rotating thread hooking shuttle move down to their respective initial positions. The winding rotation positioning platform rotates synchronously and rotates to the next hole position, and the threading needle carries the binding wire and penetrates the hole of the stator coil again. The binding wire is hooked by the front section of the three-dimensional smooth spiral rising curve and rotated to form a wire loop. The threading needle and the rotating wire hooking shuttle move up to the top of the stator coil at the same time and hook the wire rope again. During the rotation, the upper wire loop falls off and retreats. The rotating wire hooking shuttle rotates synchronously, and the upper wire loop falls off to form a knot. The threading needle and the rotating wire hooking shuttle move down back to their respective starting positions, and the cycle is repeated until the stator coil completes one rotation and the binding wire is tied. After the binding line is tied, the binding line is hooked up by the wire hooking and cutting mechanism, clamped, and then the binding line is cut, and then the binding line of the next product is tied; when the needle is retracted after tying a knot, the binding line tying method also includes tightening the binding line in the reverse direction, and when the needle is retracted after tying a knot at the front end, the brake cylinder of the tensioning mechanism presses the wire feeding end, tightens the upper and lower shafts to rise, and tightens the knot tied at the front end in reverse, and the force during the tightening process is fed back by the tension sensor and the tension range is set to ensure that the tension of each knot is consistent, and the rear binding line tension feeding device ensures that the binding line is continuously fed in a stable and tight state with the set tension torque.

[0046] The following will describe the micro motor winding binding mechanism provided by the embodiment of the present invention with reference to the accompanying drawings, wherein Figure 2 This is a schematic diagram of the overall mechanism layout in an embodiment of the present utility model; Figure 3-5 、 Figure 9-13 6-8 are schematic diagrams of the knotting process of the needle threading and the rotary hook shuttle in the embodiment of the present invention.
[0047] like Figure 6A-8 , 12 and 13, according to an embodiment of the present invention, the micro motor winding binding mechanism includes a micro motor winding stator coil on which a winding rotation positioning platform is placed, a threading needle equipped with a binding line and capable of shifting up and down and forward and backward, and a spiral thread hook shuttle that cooperates with the threading needle to form a binding line binding and knotting and can shift up and down and rotate;
[0048] The positioning platform includes a product concentric positioning support and a product clamp, the stator coil is arranged on the concentric positioning support, and the inner side of the product clamp clamps the stator coil; the threading needle is placed on the outside of the stator coil, and the front section of the threading needle has a binding wire avoidance gap and a threading hole for passing the binding wire; the spiral thread hooking shuttle is arranged above the hollow hole of the stator coil, and the spiral thread hooking shuttle has a three-dimensional smooth spiral rising surface, and the three-dimensional smooth spiral rising surface spirally rises from the front end with a cross-sectional angle changing from small to large, and has a front section that hooks the binding wire to form a wire loop and a rear section that further rotates after the wire loop is formed to make the binding wire fall off.
[0049] The process is to place the stator coil of the micro motor winding on the product concentric positioning support of the winding rotation positioning platform, position it and fix it, the winding rotation positioning platform rotates to the starting position angle or sets the stator coil at the starting position angle at the beginning, and the threading needle with the input binding line starts from the starting position and penetrates from the hole on the stator coil, the rotating thread hooking shuttle moves down from the top, and uses the three-dimensional smooth spiral rising curved front section of the rotating thread hooking shuttle to rotate and hook the binding line through the binding line avoidance notch on the threading needle, and further rotates when the threading needle is withdrawn, and uses the three-dimensional smooth rotating rising curved surface to form a wire loop, and when the threading needle withdraws from the stator coil, it moves up synchronously with the rotating thread hooking shuttle to above the stator coil, and penetrates the wire loop for the second time, and the rotating thread hooking shuttle continues to rotate. The threading needle and the rotating thread hook shuttle move down to their respective starting positions, and the winding rotation positioning platform rotates synchronously and rotates to the next hole position. The threading needle carries the binding line and passes through the hole of the stator coil again. The binding line is hooked by the front section of the three-dimensional smooth spiral rising curve and rotated to form a thread loop. The threading needle retreats, and the threading needle and the rotating thread hook shuttle move up to above the stator coil at the same time. The threading needle passes through the thread loop again and retreats, and the rotating thread hook shuttle rotates synchronously to hook the thread rope again. The upper thread loop falls off during the rotation to form a knot, and the threading needle and the rotating thread hook shuttle move down back to their respective starting positions, and the cycle continues until the stator coil completes one rotation and the binding line is tied.
[0050] According to some embodiments of the present invention, the front section angle of the three-dimensional smooth spiral rising curve is less than or equal to 40 degrees. Preferably, the front section angle is less than 10 degrees.
[0051] According to some embodiments of the present invention, the angle of the front section of the three-dimensional smooth spiral rising curve gradually increases from a small angle to a larger angle, and the angle of the rear section of the three-dimensional smooth spiral rising curve is less than 80 degrees. Preferably, the angle of the rear section of the three-dimensional smooth spiral rising curve is less than 60 degrees.
[0052] The front section of the three-dimensional smooth spiral rising surface is used to insert into the binding wire avoidance gap of the needle threading. The cross section of the front section can start from 0 degrees, that is, it can be a flat horizontal structure, gradually spiraling up and gradually tilting towards the rear end. After the front section passes through the binding wire avoidance gap and picks up the binding wire, it rotates itself and drives the binding wire to distribute around the curved surface and form a wire loop, so that the needle can pass through the wire loop. When it rotates to a preset angle, the binding wire falls off the rotating hook shuttle, and the knot is completed when the needle threading is withdrawn.
[0053] In some embodiments, the rotary thread hook shuttle is installed on a rotary thread hook shuttle motion mechanism, and the threading needle is installed on a threading motion mechanism.

[0054] The utility model also provides a device based on the micro motor winding binding mechanism:
[0055] Including the above-mentioned micro motor winding binding mechanism.
[0056] According to one embodiment of the present invention, Figure 11 As shown, the device also includes a wire hooking and cutting mechanism, which includes a binding wire hook for hooking the binding wire, a wire hook clamping mechanism and a wire end cutting mechanism, and the wire end cutting mechanism includes a starting scissors, and the binding wire hook is installed on the hook forward and backward movement mechanism.

[0059] According to some embodiments of the present invention, Figure 9 As shown, the equipment also includes a wire reverse tensioning mechanism, which includes a wire tensioning upper and lower shafts, a wire tensioning tension sensor, a wire tensioning brake cylinder, and a plurality of pulleys for bypassing the binding wire. The binding wire passes through the plurality of pulleys and the clamping mechanism of the wire tensioning brake cylinder and is connected to the feeding mechanism of the rear section. The clamping mechanism is a clamping block arranged at the front end of the wire tensioning brake cylinder. The clamping block may have a toothed structure. When clamped, the wire tensioning brake cylinder extends, and the clamping block is used to press the binding wire. The wire tensioning upper and lower shafts are pulled upward, so that the binding wire is tightened. At the same time, the tension of each knot is ensured to be consistent according to the feedback from the tension sensor.
[0060] The process is to tighten the wire in reverse. When the front needle retracts after tying a knot, the brake cylinder of the tensioning mechanism presses the wire feeding end, and the tensioning shaft rises to tighten the knot tied at the front end in reverse. The force during the tightening process is fed back by the tension sensor and the tension range is set to ensure that the tension of each knot is consistent.

After the binding wire is set, the micro motor coil is placed on the winding rotation positioning mechanism, positioned and fixed, and the position of the coil hole is adjusted by the CCD rotation correction mechanism to achieve coil hole positioning. The winding rotation positioning platform is rotated to the starting position angle or the stator coil is set at the starting position angle from the beginning. The needle threading with the binding wire starts from the starting position and pierces the hole on the stator coil. The threading needle and the rotating thread hooking shuttle move down from the top, and the front section of the three-dimensional smooth spiral rising curve of the rotating thread hooking shuttle is used to rotate and hook the binding line through the binding line avoidance notch on the threading needle, and further rotate when the threading needle is withdrawn, and a thread loop is formed by using the three-dimensional smooth rotating rising curved surface. When the threading needle is withdrawn from the stator coil, it moves up synchronously with the rotating thread hooking shuttle to above the stator coil, and inserts the thread loop for the second time and withdraws. At the same time, the rotating thread hooking shuttle continues to rotate and hooks the thread rope again. During the rotation process, the upper thread loop falls off, forming a knot on the stator coil, and the threading needle and the rotating thread hooking shuttle move down to their respective initial positions. The winding rotation positioning platform rotates synchronously and rotates to the next workstation. The threading needle carries the binding wire and penetrates the hole of the stator coil again. The binding wire is hooked by the front section of the three-dimensional smooth spiral rising curve and rotates to form a wire loop. The threading needle and the rotating wire hooking shuttle move up to the top of the stator coil at the same time. The threading needle passes through the wire loop again and retreats. The rotating wire hooking shuttle rotates synchronously and hooks the wire rope again. During the rotation, the upper wire loop falls off to form a knot. The threading needle and the rotating wire hooking shuttle move down back to their respective starting positions, and the cycle continues until the stator coil completes one rotation and the binding wire is tied. After the binding line is tied, the binding line is hooked up by the line hooking and cutting mechanism, clamped, and then the binding line is cut, and then the binding line of the next product is tied; when the needle is retracted after tying a knot, the binding line tying method also includes tightening the binding line in the reverse direction, and when the front needle is retracted after tying a knot, the brake cylinder of the tensioning mechanism presses the wire feeding end, tightens the upper and lower shafts to reversely tighten the knot tied at the front end, and the force during the tightening process is fed back by the tension sensor and the tension range is set to ensure that the tension of each knot is consistent, and the rear binding line tension feeding device ensures that the binding line is continuously fed in a stable and tight state with the set tension torque.
