Description

Technical Field

[0001] This utility model relates to the field of coil winding technology, and more specifically, to an inductor coil winding device with tension adjustment. Background Technology

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. Its structure is similar to that of a transformer, but it has only one winding.

[0003] Currently, commonly used inductor coil winding equipment uses structures such as winding rings to drive the wire to rotate around the mandrel. At the same time, the mandrel rotates, thus winding the wire around the mandrel sequentially. The tightness of the wire winding on the mandrel is related to the tension exerted on the wire by the rotating winding ring. However, different specifications of inductors use different wire specifications, with different wire diameters and different material hardness. But the tension exerted on the wire by the winding ring is constant, making it difficult to control the tightness of the winding in the final product, which affects the quality of the finished product.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] An inductor coil winding device with tension adjustment includes a worktable 1, on which a mounting plate 11 and two slide rails 2 are mounted. The two slide rails 2 are located on both sides of the mounting plate 11. Movable wheels 5 are slidably connected to the slide rails 2. A winding drive assembly 6 is mounted on the mounting plate 11. A winding ring 7 is connected to the output end of the winding drive assembly 6. The winding ring 7 is rotatably mounted on the mounting plate 11 and is sleeved with a mandrel. A mandrel drive assembly 3 is mounted on the worktable 1. The mandrel drive assembly 3 and the two movable wheels 5 can jointly clamp and drive the mandrel of the coil. The mandrel drive assembly 3 includes a motor 32, which is fixed on the worktable 1. A drive wheel 31 is mounted on the output shaft of the motor 32. The drive wheel 31 can abut against the mandrel. After the mandrel is placed inside the winding ring 7, the two movable wheels 5 are moved so that the two movable wheels 5 and the drive wheel 31 jointly clamp the mandrel. At this time, the motor 32 can drive the mandrel to rotate through the drive wheel 31.

[0026] A pressure plate 12 is rotatably connected to the mounting plate 11. A roller 13 is rotatably mounted on the free end of the pressure plate 12. The winding drive assembly 6 includes a second motor 61. A belt 63 is mounted on the output shaft of the second motor 61. Several pulleys 62 are rotatably mounted on the mounting plate 11. The belt 63 is sleeved on all the pulleys 62. The roller 13 and the several pulleys 62 are rotatably connected to the outer wall of the winding ring 7. The belt 63 surrounds the outside of the winding ring 7. During installation, the winding ring 7 is placed on the belt 63, and then the pressure plate 12 is rotated so that the roller 13 presses the winding ring 7 tightly onto the belt 63. At this time, when the second motor 61 rotates, it can drive the winding ring 7 to rotate and wind through the belt 63.

[0027] The winding ring 7 includes a ring body 71, which is a ring-shaped structure with a notch. A movable cover 72 is rotatably connected to the end of the ring body 71. The movable cover 72 can cover the ring body 71 and form a complete ring structure. A retaining plate 73 is rotatably installed on the free end of the movable cover 72. A retaining pin 74 is correspondingly provided on the ring body 71. A retaining groove 731 is provided on the retaining plate 73. The retaining pin 74 can engage with the retaining groove 731. When the movable cover 72 is opened, the mandrel can be placed into the winding ring 7 to facilitate winding.

[0028] The winding ring 7 is equipped with a wire storage assembly 8 and a wire pressing assembly 9. The wires in the wire storage assembly 8 are wound onto the mandrel after passing through the wire pressing assembly 9. When the winding ring 7 rotates, the wires on the wire storage assembly 8 rotate around the mandrel together with the winding ring 7, thereby winding the wires onto the mandrel. The wires need to pass through the wire pressing assembly 9. The wire pressing assembly 9 changes the tension on the wires between the mandrel and the wire pressing assembly 9 by changing the pressure on the surface of the wires, so as to ensure that wires of different specifications can be tightly wound onto the mandrel.

[0029] The wire storage assembly 8 includes two locking blocks 81, on which a rotating rod 82 is locked together. A reel 83 is rotatably sleeved on the rotating rod 82. The reel 83 is used for storing wire. When the winding ring 7 rotates, it pulls the wire, and the reel 83 rotates on the rotating rod 82 to automatically release the wire.

[0030] The winding ring 7 has a threading hole 75 that runs radially through it. The wire pressing assembly 9 includes a shrinking ring 91. The outer ring wall of the shrinking ring 91 is truncated cone-shaped. The large diameter end of the shrinking ring 91 is fixed on the threading hole 75. The small diameter end of the shrinking ring 91 extends away from the wire storage assembly 8. Several shrinking grooves 92 are evenly provided on the shrinking ring 91 along the axial direction. A locking ring 94 is sleeved on the shrinking ring 91. The inner wall of the locking ring 94 fits against the outer wall of the shrinking ring 91. A threaded groove 93 is provided in the threading hole 75. The outer wall of the locking ring 94 is threadedly connected to the threaded groove 93. Several blind holes 95 are provided at the end of the locking ring 94 away from the wire storage assembly 8.

[0031] After the wire passes through the shrink ring 91, it is connected to the mandrel. Rotating the locking ring 94 can adjust the degree of shrinkage of the shrink ring 91, thereby changing the inner diameter of the wire clamping assembly 9. This changes the pressure of the wire clamping assembly 9 on the surface of the wire. By applying force to the surface of the wire and changing the tension on the wire between the wire clamping assembly 9 and the mandrel, it is possible to ensure that wires of different specifications can be tightly wound on the mandrel, thus ensuring the winding quality.

[0032] Specifically, a wire pressing assembly 9 is provided on the winding ring 7. The wires on the wire storage assembly 8 are wound onto the mandrel after passing through the wire pressing assembly 9. The shrinking ring 91 of the wire pressing assembly 9 is sleeved on the wire. Several shrinking grooves 92 are provided on the shrinking ring 91 along the axial direction. Rotating the locking ring 94 can drive the shrinking ring 91 to be squeezed or loosened towards the ring axis, thereby adjusting the pressure of the shrinking ring 91 on the surface of the wire. That is, it can adjust the traction force on the wire when the winding ring 7 rotates, so that wires of different specifications can be tightly wound on the surface of the mandrel.
