Description

Technical Field

[0001] This utility model belongs to the technical field of inductor production equipment, and in particular relates to a tensioning mechanism for winding inductor production. Background Technology

[0002] In inductor production, copper wire needs to be wound onto a spool. Before automated winding, the wire is pulled from the spool and fed into the winding assembly. During this feeding process, as the wire is unwound, the spool's mass decreases, reducing its inertia. If the tension control system does not adequately compensate for this change in inertia, tension fluctuations and jitter can occur. Wire jitter prevents precise and tight alignment on the bobbin or core. This can lead to uneven turn spacing, wire overlap, wire merging, or even skipped wires, and can also cause irregular inductor coil shapes, affecting the coil's geometry and resulting in significant deviations in key electrical parameters such as inductance and Q value.

[0003] To address these issues, we provide a tensioning mechanism for inductor winding production. Utility Model Content

A tension wheel is rotatably installed in a tension wheel sleeve fitted at one end of the tensioning wheel rod. The wire is passed around the tension wheel, and the pull rod assembly pulls the tensioning wheel rod, causing the tensioning wheel rod to move and adjust the tension of the wire. A straightening assembly is installed on one side of the side plate frame.

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments and the accompanying drawings. Example 1

[0018] Please see Figures 1 to 3 This utility model is a tensioning mechanism for winding inductor production, including a side frame plate 1, a tensioning wheel rod 2, a pull rod assembly 3, and a straightening assembly 4. An adapter sleeve 201 is fixedly installed at one end of the tensioning wheel rod 2. A rotating shaft 201a is fixedly mounted on the side of the adapter sleeve 201 and rotatably installed on the side frame plate 1. The pull rod assembly 3 installed on the side frame plate 1 is connected to the tensioning wheel rod 2. A tension wheel 201c is rotatably installed in a tension wheel sleeve 201b fitted at one end of the tensioning wheel rod 2. The wire is passed around the tension wheel 201c, and the pull rod assembly 3 pulls the tensioning wheel rod 2, causing the tensioning wheel rod 2 to drive the tension wheel 201c to move, thus adjusting the tension of the wire by the tension wheel 201c. A straightening assembly 4 is installed on one side of the side frame plate 1. The wire passes through the straightening assembly 4, and the straightening assembly 4 straightens the wire, preventing bending of the wire from affecting wire transport and winding.

[0019] Specifically, one end of the tensioning wheel rod 2 is fixedly sleeved with an adapter sleeve 201, and a rotating shaft 201a is fixedly provided on one side of the adapter sleeve 201. The rotating shaft 201a is rotatably mounted on the plate surface of the side frame plate 1. One end of the tie rod assembly 3 is rotatably mounted on the plate surface of the side frame plate 1. The end of the tie rod assembly 3 away from the adapter end of the side frame plate 1 is connected to the tensioning wheel rod 2 for transmission. The end of the tensioning wheel rod 2 away from the adapter sleeve 201 is fixedly sleeved with a tension wheel sleeve 201b. A tension wheel 201c is rotatably installed inside the tension wheel sleeve 201b. The straightening assembly 4 is set on one side of the plate surface of the side frame plate 1.

[0020] Furthermore, the pull rod assembly 3 includes a compression spring sleeve 301, a pull rod 302, and a compression spring 303. The compression spring 303 is sleeved inside the compression spring sleeve 301. One end of the compression spring sleeve 301 is fixedly sleeved with a sleeve end cap 301a. A transition shaft 301a-1 is fixedly mounted on one side of the sleeve end cap 301a. The transition shaft 301a-1 is rotatably mounted on the surface of the side frame plate 1. The pull rod 302 is sleeved inside the compression spring 303. One end of the pull rod 302 near the sleeve end cap 301a is fixedly... There is a spring end cap 302a, the end face of which is attached to one end of the compression spring 303. The pull rod 302 slides through the closed end face of the compression spring cylinder 301 away from the cylinder end cover 301a. The end of the pull rod 302 that passes through the cylinder end cover 301a is connected to the tension wheel rod 2. The compression spring 303 pushes the spring end cap 302a, which causes the spring end cap 302a to drive the pull rod 302 to pull the tension wheel rod 2, so that the tension wheel 201c at the front end of the tension wheel rod 2 tightens the thread.

[0021] Furthermore, a rod sleeve 302b is rotatably mounted on the end of the pull rod 302 away from the spring cap 302a, and the rod sleeve 302b is slidably sleeved on the outside of the tension wheel rod 2.

[0022] Furthermore, a push rod screw 302b-1 is threaded onto one side of the rod sleeve 302b. The end face of the push rod screw 302b-1 is attached to the rod wall of the tension wheel rod 2. By sliding the adjusting rod sleeve 302b, the compression force of the compression spring cap 302a at one end of the pull rod 302 on the compression spring 303 is adjusted, and the direction of the tension force of the pull rod 302 on the tension wheel rod 2 is changed, thereby adjusting the tension force of the pull rod assembly 3 on the tension wheel rod 2.

[0023] The operation process in this embodiment is as follows: After the thread is pulled out of the spool, it first passes through the straightening assembly 4, then the thread is wrapped around the tension wheel 201c. The sliding sleeve 302b on the tension wheel rod 2 is slidably adjusted to a suitable position so that the pulling force of the pull rod assembly 3 on the tension wheel rod 2 can straighten and tighten the thread without breaking it. Then the top screw 302b-1 is tightened to fix the sliding sleeve 302b on the tension wheel rod 2. When the thread is being conveyed, the thread vibrates as it is conveyed, causing the tension wheel 201c to drive the tension wheel rod 2 to swing. The pull rod assembly 3 tightens the tension wheel rod 2, keeping the thread wound on the tension wheel 201c taut. Example 2

[0024] Please see Figures 1 to 5 Based on embodiment 1, the straightening assembly 4 includes four clamping wheels 401 and one straightening wheel 402. By passing the wire through the two clamping wheels 401 and winding the wire around the wheel surface of the straightening wheel 402, the straightening wheel 402 straightens the wire, preventing the bends in the wire from being wound into the inductor and affecting the quality of the inductor.

[0025] Specifically, four wire clamping wheels 401 are rotatably mounted on the surface of the side frame plate 1. Every two wire clamping wheels 401 form a wire clamping wheel group. The wheel surfaces of the two wire clamping wheels 401 in each wire clamping wheel group are in contact with each other. The two wire clamping wheel groups are arranged vertically. The outer side of the straightening wheel 402 is rotatably sleeved with a wheel slide seat 402a. A slide seat groove 101 is opened horizontally on the surface of the side frame plate 1. One side of the wheel slide seat 402a is slidably sleeved in the slide seat groove 101.

[0026] Furthermore, a threaded sleeve 102 is fixedly provided on the surface of the side frame plate 1. An adjusting screw 102a is screwed into the threaded sleeve 102. One end of the adjusting screw 102a is connected to one end face of the slide groove 101.

[0027] Furthermore, a buffer spring 402a-1 is fixedly connected to one end face of the pulley block 402a, and a spring end sleeve 402a-2 is fixedly connected to the end of the buffer spring 402a-1 away from the pulley block 402a. One end of the adjusting screw 102a is attached to the end face of the spring end sleeve 402a-2. Rotating the adjusting screw 102a causes one end of the adjusting screw 102a to push the spring end sleeve 402a-2, causing the spring end sleeve 402a-2 to compress the buffer spring 402a-1. The buffer spring 402a-1 pushes the pulley block 402a to move in the slide block groove 101, adjusting the straightening force of the straightening wheel 402 on the thread. The buffer spring 402a-1 provides elastic tension under the push of the adjusting screw 102a, avoiding overload damage to the thread.

[0028] The operation process in this embodiment is as follows: The wire is wrapped around the straightening wheel 402 and clamped by two clamping wheels. The adjusting screw 102a is rotated so that one end of the adjusting screw 102a pushes the spring end sleeve 402a-2, which in turn squeezes the buffer spring 402a-1. The buffer spring 402a-1 pushes the wheel slide 402a to move in the slide groove 101, thus adjusting the straightening force of the straightening wheel 402 on the wire. The straightening wheel 402 straightens the wire, preventing bends in the wire from getting caught in the inductor and affecting the quality of the inductor.
