[0002] A wire-wound inductor is a passive electronic component used to store and release magnetic energy. It is made by winding a wire into a spiral coil with one or more turns. The manufacturing process of the inductor includes winding, soldering, and molding, among which winding is an important part of the inductor manufacturing process.

[0003] There are generally two ways to wind inductors. One is to purchase a winding machine, but traditional winding machines are expensive and not cost-effective. The other is online customization, but the customization cycle is relatively long, and the price is not cost-effective when the quantity is small. Summary of the invention

[0004] The present invention provides an inductor winding tool, which aims to solve the problem that there are generally two ways to wind the inductor in the prior art: one is to purchase a winding machine, but traditional winding machines are expensive and have a low cost-effectiveness; the other is online customization, but the customization cycle is relatively long and the price is not cost-effective when the quantity is small.

[0005] An embodiment of the present invention provides an inductor winding tool, including a base, wherein the upper end of the base is fixedly connected to a bearing seat, a wire clamping shaft is arranged on the bearing seat, the bearing seat and the wire clamping shaft are rotatably connected via a bearing member, an inductor winding needle is arranged at one end of the wire clamping shaft, the wire clamping shaft and the inductor winding needle are connected via a locking nut, the other end of the wire clamping shaft is fixedly connected to a rotating plate, two rotating heads are symmetrically fixedly connected to the rotating plate, a thin copper wire is wound around the inductor winding needle, a self-maintenance component is arranged inside the bearing seat and above the bearing member, and a recovery component is arranged inside the bearing seat and below the bearing member.

[0006] By adopting the above technical scheme, when working, the inductor winding needle is inserted into the tapered mouth of the wire clamping shaft, the locking nut is screwed into the wire clamping shaft, the inductor winding needle is locked, and then the copper wire on the base is wound around the inductor winding needle through the rotation of the wire clamping shaft to complete the inductor production. During the winding process, the self-maintenance component automatically maintains the bearing parts to ensure the smoothness of the rotation of the wire clamping shaft and the service life of the device. At the same time, the excess engine oil can be recovered through the recovery component and pressed back into the self-maintenance component for reuse, saving resources. The entire device has a simple structure, low cost, simple operation and easy maintenance, and is easy to customize and has high production efficiency.

[0007] Furthermore, one end of the wire clamping shaft away from the bearing seat is tapered, and a cross cut is provided at the end thereof.

[0008] By adopting the above technical solution, the inductor winding needle can be clamped, making it convenient to wind the micro inductor.

[0009] Furthermore, the bearing component includes an outer ring arranged in the bearing seat and an inner ring arranged outside the wire clamping shaft, a bracket is arranged between the outer ring and the inner ring, a steel ball is rotatably arranged on the bracket, one side of the steel ball is embedded in the outer wall of the inner ring, the steel ball can roll on the wall surface of the outer ring and the inner ring, and sealing rings are arranged on both sides between the outer ring and the inner ring.

[0010] By adopting the above technical solution, the rotational connection between the clamping shaft and the bearing seat is achieved, and the sealing of the cavity between the outer ring and the inner ring is ensured.

[0011] Furthermore, the self-maintenance component includes a guide hole opened at the top of the outer ring and a storage chamber and an injection hole opened in the bearing seat, the guide hole is arc-shaped, the upper end of the guide hole is connected to the bottom of the storage chamber, the lower end of the guide hole is open and connected to the cavity between the outer ring and the inner ring, the lower end of the injection hole is connected to the top of the storage chamber, the storage chamber is filled with organic oil, the upper end of the injection hole extends out of the bearing seat, and the mouth of the guide hole is provided with a sealing unit, which can be pushed open by the steel ball.

[0012] By adopting the above technical solution, when the steel ball rotates to the sealing unit, the steel ball activates the sealing unit and opens the mouth of the lower end of the guide hole, allowing the oil in the storage chamber to flow into the cavity between the outer ring and the inner ring. At the same time, the steel ball contacts the oil to achieve the purpose of automatic maintenance. When the steel ball moves away from the sealing unit, the sealing unit activates and closes the mouth of the lower end of the guide hole again to prevent the oil from continuing to flow out and causing excessive oil to cause the bearing to fail to work normally.

[0013] Furthermore, the blocking unit includes a telescopic rod fixedly connected to the upper wall of the storage chamber, a return spring 1 is sleeved on the outer side of the telescopic rod, a support block is fixedly connected to the lower end of the telescopic rod, both ends of the return spring 1 are respectively connected to the support block and the upper wall of the storage chamber, a leak-proof ball is provided at the lower end of the support block, and the leak-proof ball is pressed against the mouth of the lower end of the guide hole under the action of the return spring 1, and the bottom of the leak-proof ball extends out of the mouth of the lower end of the guide hole and can contact the steel ball.

[0014] By adopting the above technical solution, when the steel ball rotates to the blocking unit, the steel ball pushes the anti-leakage ball, the reset spring 1 is compressed, and the telescopic rod contracts. At this time, the anti-leakage ball opens the mouth of the lower end of the guide hole, allowing the oil in the storage chamber to be released into the cavity between the outer ring and the inner ring, thereby realizing automatic maintenance of the bearing component, improving the smoothness and service life of the device during use, and when the steel ball moves away from the anti-leakage ball, under the deformation force of the reset spring 1, the anti-leakage ball is pressed tightly against the mouth of the lower end of the guide hole, thereby blocking the mouth of the lower end of the guide hole and preventing excessive oil from flowing into the bearing component.

[0015] Furthermore, the recovery component includes a collection chamber and a guide groove opened in the bearing seat, the guide groove is funnel-shaped, the upper end of the guide groove is connected to the cavity between the outer ring and the inner ring through a flow hole, one side of the lower end of the collection chamber is connected to the upper end of the storage chamber through a channel, the middle of the upper end of the collection chamber is connected to the middle of the lower end of the guide groove, a piston is slidably installed in the collection chamber, the piston divides the collection chamber into a left cavity and a right cavity, and the lower end of the piston is provided with a left-right through-through conduction hole A hole is provided in the conducting hole, and a one-way valve is provided in the conducting hole. The engine oil in the right chamber can flow into the left chamber through the one-way valve. A piston rod is provided at the right end of the piston. The end of the piston rod away from the piston movably extends out of the bearing seat. The end of the piston rod away from the piston is provided with an inclined surface. A return spring 2 is provided on the outer side of the piston rod. The two ends of the return spring 2 are respectively connected to the right wall surface of the piston and the right wall surface of the collecting chamber. When the rotating plate rotates, it contacts and squeezes the inclined surface, so that the piston rod moves toward the collecting chamber.

[0016] By adopting the above technical scheme, the excess engine oil flows downward to the circulation hole under its own gravity, flows into the guide groove through the circulation hole, and then flows into the collection chamber for collection by the guide groove. When the device is winding, the rotating plate rotates the extrusion inclined surface during the rotation process, so that the piston rod moves toward the collection chamber, the return spring 2 extends, and the piston rod pushes the piston to move in the collection chamber. The piston squeezes the engine oil in the collection chamber and returns to the storage chamber through the channel for continued use, thereby avoiding the waste of engine oil. When the piston moves to the left, the guide groove is connected with the right chamber. At this time, during the continued movement of the piston, the engine oil in the guide groove can be sucked and dropped into the collection chamber, and then the excess engine oil in the cavity between the outer ring and the inner ring can be sucked. When the rotating plate leaves the piston rod, the piston slowly resets under the deformation force of the return spring 2. During the piston resetting process, the piston squeezes the engine oil in the right chamber and transports it to the left chamber through the guide hole, thereby ensuring that the excess engine oil can return to the storage chamber for continued use.

[0018] When the present invention is working, the inductor winding needle is inserted into the tapered mouth of the wire clamping shaft, the locking nut is screwed into the wire clamping shaft, the inductor winding needle is locked, and then the copper wire on the base is wound around the inductor winding needle through the rotation of the wire clamping shaft to complete the inductor production. During the winding process, the self-maintenance component automatically maintains the bearing part to ensure the smoothness of the rotation of the wire clamping shaft and the service life of the device. At the same time, the excess engine oil can be recovered through the recovery component and pressed back into the self-maintenance component for reuse, thereby saving resources.

[0031] Reference Figure 2 and Figure 3 The end of the wire clamping shaft 4 away from the bearing seat 2 is tapered, and a cross cut is opened at its end, which can clamp the inductor winding needle 8 to facilitate the winding of the miniature inductor.

[0032] Reference Figure 3 and Figure 4 The bearing member 3 includes an outer ring 31 arranged in the bearing seat 2 and an inner ring 32 arranged outside the clamping shaft 4. A bracket 33 is arranged between the outer ring 31 and the inner ring 32. A steel ball 34 is rotatably arranged on the bracket 33. One side of the steel ball 34 is embedded in the outer wall of the inner ring 32. The steel ball 34 can roll on the wall surface of the outer ring 31 and the inner ring 32. Sealing rings 35 are arranged on both sides between the outer ring 31 and the inner ring 32, which realizes the rotational connection between the clamping shaft 4 and the bearing seat 2 and ensures the sealing of the cavity between the outer ring 31 and the inner ring 32.

[0033] Reference Figure 3 and Figure 4 The self-maintenance component 10 includes a guide hole 101 opened at the top of the outer ring 31, a storage chamber 102 and an injection hole 103 opened in the bearing seat 2, the guide hole 101 is arc-shaped, the upper end of the guide hole 101 is connected to the bottom of the storage chamber 102, the lower end of the guide hole 101 is open and connected to the cavity between the outer ring 31 and the inner ring 32, the lower end of the injection hole 103 is connected to the top of the storage chamber 102, the storage chamber 102 is filled with organic oil, the upper end of the injection hole 103 extends out of the bearing seat 2, and a sealing unit is provided at the mouth of the guide hole 101, which can be pushed open by the steel ball 34.

[0034] When the steel ball 34 rotates to the blocking unit, the steel ball 34 activates the blocking unit and opens the lower end of the guide hole 101, allowing the oil in the storage chamber 102 to flow into the cavity between the outer ring 31 and the inner ring 32. At the same time, the steel ball 34 contacts the oil to achieve the purpose of automatic maintenance. When the steel ball 34 moves away from the blocking unit, the blocking unit activates and closes the lower end of the guide hole 101 again to prevent the oil from continuing to flow out and causing excessive oil to cause the bearing component 3 to fail to work normally.

[0035] Reference Figure 4 The blocking unit includes a telescopic rod 105 fixedly connected to the upper wall of the storage chamber 102, a return spring 104 is sleeved on the outer side of the telescopic rod 105, a support block 106 is fixedly connected to the lower end of the telescopic rod 105, both ends of the return spring 104 are respectively connected to the support block 106 and the upper wall of the storage chamber 102, a leak-proof ball 107 is provided at the lower end of the support block 106, and the leak-proof ball 107 is pressed against the mouth of the lower end of the guide hole 101 under the action of the return spring 104, and the bottom of the leak-proof ball 107 extends out of the mouth of the lower end of the guide hole 101 and contacts with the energy steel ball 34.

[0036] When the steel ball 34 rotates to the blocking unit, the steel ball 34 pushes the anti-leakage ball 107, the reset spring 104 is compressed, and the telescopic rod 105 contracts. At this time, the anti-leakage ball 107 opens the mouth of the lower end of the guide hole 101, allowing the oil in the storage chamber 102 to be released into the cavity between the outer ring 31 and the inner ring 32, thereby realizing automatic maintenance of the bearing component 3, improving the smoothness and service life of the device during use. When the steel ball 34 moves away from the anti-leakage ball 107, under the deformation force of the reset spring 104, the anti-leakage ball 107 is pressed tightly against the mouth of the lower end of the guide hole 101, thereby blocking the mouth of the lower end of the guide hole 101 and preventing excessive oil from flowing into the bearing component 3.

[0037] Reference Figure 3 , Figure 5 and Figure 6The recovery component 11 includes a collection chamber 111 and a guide groove 112 opened in the bearing seat 2. The guide groove 112 is funnel-shaped. The upper end of the guide groove 112 is connected to the cavity between the outer ring 31 and the inner ring 32 through a flow hole 113. One side of the lower end of the collection chamber 111 is connected to the upper end of the storage chamber 102 through a channel 114. The middle of the upper end of the collection chamber 111 is connected to the middle of the lower end of the guide groove 112. A piston 115 is slidably installed in the collection chamber 111.

A one-way valve is provided in the through hole 116, and the engine oil in the right chamber can flow into the left chamber through the one-way valve. A piston rod 117 is provided at the right end of the piston 115, and the end of the piston rod 117 away from the piston 115 is movably extended out of the bearing seat 2, and the end of the piston rod 117 away from the piston 115 is provided with an inclined surface 118. A return spring 119 is provided on the outer side of the piston rod 117, and the two ends of the return spring 119 are respectively connected to the right wall surface of the piston 115 and the right wall surface of the collection chamber 111. When the rotating plate 6 rotates, it contacts and squeezes the inclined surface 118, so that the piston rod 117 moves toward the collection chamber 111.

[0038] The excess oil flows downward to the flow hole 113 under its own gravity, flows into the guide groove 112 through the flow hole 113, and then flows into the collection chamber 111 through the guide groove 112 for collection. When the device is winding, the rotating plate 6 rotates the extrusion slope 118 during the rotation process, so that the piston rod 117 moves toward the collection chamber 111, the return spring 119 extends, the piston rod 117 pushes the piston 115 to move in the collection chamber 111, and the piston 115 squeezes the oil in the collection chamber 111 and returns to the storage chamber 102 through the channel 114 for continued use, thereby avoiding the waste of oil. When the plug 115 moves to the left, the guide groove 112 is connected to the right chamber. At this time, as the piston 115 continues to move, the oil in the guide groove 112 can be sucked and dropped into the collection chamber 111, and then the excess oil in the cavity between the outer ring 31 and the inner ring 32 can be sucked. When the rotating plate 6 leaves the piston rod 117, the piston 115 slowly resets under the deformation force of the reset spring 119. During the reset process of the piston 115, the piston 115 squeezes the oil in the right chamber and transports it to the left chamber through the guide hole 116, ensuring that the excess oil can return to the storage chamber 102 for continued use.
