Description

Technical Field

[0001] This utility model relates to the field of transformer processing technology, specifically to a stripping and wire feeding mechanism. Background Technology

[0002] In the manufacturing process of electromagnetic components such as transformers and inductors, coil winding is one of the key processes. Before using enameled wire or other wires for winding, it is currently necessary to remove the insulation from the ends of the wires to expose the internal metal conductors for subsequent welding. In related technologies, current automated transformer winding equipment usually integrates an automatic wire stripping mechanism, which is mainly used to strip the wire ends before the winding process. However, existing wire stripping mechanisms have difficulty controlling the stripping depth. If the stripping depth is too large, it is easy to cut the internal wire core, which damages the wire core and reduces its mechanical strength, making it prone to breakage during subsequent winding. If the stripping depth is too shallow, some insulation material may remain on the surface of the wire core, resulting in weak subsequent electrical connections. It is difficult to accurately adjust the stripping depth according to the wire diameter, resulting in poor stripping effect. Utility Model Content

[0023] The stripping and wire feeding mechanism of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 As shown, the wire stripping and feeding mechanism provided in this embodiment of the present invention includes: a base plate 10, a support plate 20, a wire feeding assembly 30, a stripping assembly 40, and an adjusting assembly 50. The support plate 20 is disposed on the base plate 10 in a vertical direction; the wire feeding assembly 30 is disposed on the support plate 20 and is used to feed the wire 60 in a vertical direction; the stripping assembly 40 is movably disposed on the support plate 20 in a vertical direction and is located in the wire feeding direction of the wire feeding assembly 30, and the stripping assembly 40 has a stripping opening 442 for clamping the wire 60; the adjusting assembly 50 is disposed on the stripping assembly 40 and is used to adjust and limit the stripping size of the stripping opening 442 when the stripping opening 442 is closed.

[0025] Reference Figure 2 and Figure 3As shown, the wire feeding assembly 30 includes: a first motor 31, a gear set 32, and at least three wire feeding rollers 33. The first motor 31 is mounted on the base plate 10; the gear set 32 ​​is rotatably mounted on the support plate 20 and is connected to the first motor 31 in a transmission manner; at least three wire feeding rollers 33 are connected to the gear set 32, and a wire feeding gap for feeding wire 60 is formed between adjacent two wire feeding rollers 33. The gear set 32 ​​includes: a driving gear 321 and at least two driven gears 322. The driving gear 321 is mounted on the motor shaft of the first motor 31 and is connected to at least one wire feeding roller 33, so that the first motor 31 can drive the driving gear 32. 1. Rotation causes the wire feeding wheel 33 connected to the drive gear 321 to rotate synchronously. At least two driven gears 322 are respectively located on both sides of the drive gear 321 and mesh with the drive gear 321. At least two wire feeding wheels 33 are respectively connected to at least two driven gears 322. When the drive gear 321 drives at least two driven gears 322 to rotate synchronously, the two wire feeding wheels 33 connected to the two driven gears 322 can rotate synchronously. Since the wire 60 is located in the wire feeding gap and is clamped by at least three wire feeding wheels 33, the rotation of at least three wire feeding wheels 33 can drive the wire harness to be transported and moved, resulting in a higher degree of automation.

[0026] Reference Figure 4 and Figure 5 As shown, the peeling assembly 40 includes: a pneumatic gripper 41, a first moving block 42, a second moving block 43, and two peeling blades 44. The pneumatic gripper 41 is movably mounted on the support plate 20 in the vertical direction; the first moving block 42 is mounted on one gripper finger of the pneumatic gripper 41; and the second moving block 43 is mounted on the other gripper finger of the pneumatic gripper 41. This allows the pneumatic gripper 41 to drive the first moving block 42 and the second moving block 43 to close or separate from each other. The two peeling blades 44 are respectively mounted on the first moving block 42 and the second moving block 43, and move away from or close together with the first moving block 42 and the second moving block 43.

[0027] In this embodiment, when the wire 60 is fed into the stripping opening 442 via the wire feeding wheel 33, the pneumatic gripper 41 drives the first moving block 42 and the second moving block 43 to close together, so that the two stripping blades 44 close together with the first moving block 42 and the second moving block 43. The stripping opening 442 defined by the blade portion 441 of each stripping blade 44 can be retracted with the two stripping blades 44 and cut into the sheath of the wire 60. Then, by moving the two stripping blades 44 along the axial direction of the wire 60, the stripping action of the sheath of the wire 60 can be completed, and the degree of automation is stronger. It can be understood that the blade portion 441 is composed of two inclined surfaces that form an angle with each other.

[0028] Reference Figures 4 to 6As shown, the adjustment assembly 50 includes an adjustment knob 51, a limiting member 52, and an elastic member 53. The adjustment knob 51 is rotatably threaded to the side of the first moving block 42. The limiting member 52 is slidably disposed within the first moving block 42 and coaxially arranged with the adjustment knob 51. One end of the limiting member 52 extends through the first moving block 42 toward the second moving block 43, and the other end abuts against the adjustment knob 51. By rotating the adjustment knob 51, it moves toward or away from the limiting member 52, so that the limiting member 52 moves between the first moving block 42 and the second moving block 43. The position between the moving blocks 43 is adjustable, so that the distance between the first moving block 42 and the second moving block 43 can be adjusted with the limiting member 52. The elastic member 53 is disposed in the first moving block 42 and sleeved on the circumferential surface of the limiting member 52. The two ends of the elastic member 53 abut against the limiting member 52 and the first moving block 42 respectively. The elastic member 53 elastically pushes the limiting member 52 against the adjusting knob 51, so that the limiting member 52 can be pressed and fixed in the first moving block 42 by the elastic member 53 and the adjusting knob 51 to maintain a stable state.

[0029] In this embodiment, a sliding cavity 421 is provided in the first moving block 42, and a limiting member 52 is slidably disposed in the sliding cavity 421. The limiting member 52 includes a stop portion 521 and an abutment portion 522. The stop portion 521 is disposed in the sliding cavity 421 and abuts against the adjusting knob 51. The abutment portion 522 is connected to the stop portion 521 and extends from the sliding cavity 421 toward the second moving block 43. An elastic member 53 is sleeved on the abutment portion 522 and elastically pushes the stop portion 521 toward the adjusting knob 51. By rotating the adjusting knob 51, the adjusting knob 51 can limit the length of the abutment portion 522 extending out of the sliding cavity 421, so that when the first moving block 42 and the second moving block 43 are closed together, the extended abutment portion 522 abuts against the second moving block 43. When stripping the wire 60, the distance between the two stripping blades 44 is limited by the limiting member 52, allowing the two stripping blades 44 to accurately cut into the outer sheath of the wire 60. It is understood that when a deeper cut is needed, the adjusting knob 51 can be rotated away from the limiting member 52, so that when the two stripping blades 44 are closed, the stripping opening 442 can be reduced to a smaller size to complete the cutting action. When a shallower cut is needed, the adjusting knob 51 can be rotated closer to the limiting member 52, so that when the two stripping blades 44 are closed, the space of the stripping opening 442 is larger to complete the cutting action. Therefore, it can be used to strip wires 60 of different diameters, with a wider range of applications and more accurate stripping precision.

[0030] As a preferred method, the adjustment knob 51 is marked with scale lines 511 on its circumference. The scale lines 511 are marked at intervals around the axial direction of the adjustment knob 51, so that when adjusting the cutting depth of the two peeling knives 44, the adjustment can be manually observed through the scale lines 511, ensuring more accurate and precise adjustment.

[0031] Reference Figure 4 As shown, the peeling assembly 40 further includes: a fixed plate 45, a second motor 46, a lead screw 47, a connecting plate 48, and a sliding plate 49. The fixed plate 45 is disposed on the support plate 20; the second motor 46 is fixed on the support plate 20; the lead screw 47 is connected to the second motor 46 and extends vertically to be driven to rotate by the second motor 46; the connecting plate 48 is threadedly connected to the lead screw 47 and is driven by the lead screw 47 to move vertically; the sliding plate 49 is slidably connected to the slide rail disposed on the support plate 20 through a slider, and the sliding plate 49 is connected to the connecting plate 48, and the pneumatic gripper 41 is fixed to the end of the sliding plate 49.

[0032] In this embodiment, when the pneumatic gripper 41 drives the two stripping blades 44 to cut into the sheath of the wire 60, the second motor 46 can drive the lead screw 47 to rotate, so that the connecting plate 48 can drive the sliding plate 49 to move vertically and away from the wire 60. Then, the sliding plate 49 can drive the pneumatic gripper 41 and the two stripping blades 44 to move and remove the cut sheath from the wire 60, making the stripping efficiency and automation of the wire 60 higher.

[0033] The wire stripping and feeding mechanism provided by this utility model conveys the wire 60 to the stripping opening 442 of the stripping assembly 40 through the wire feeding component 30. This allows the stripping assembly 40 to clamp the wire 60 and move it vertically to complete the stripping action. Before stripping the wire 60, the adjusting component 50 can be adjusted to limit the stripping size of the stripping opening 442. Thus, the stripping depth can be accurately controlled by the adjusting component 50 according to the wire diameter of the wire 60, avoiding damage to the wire core or insulation material residue on the surface of the wire core, resulting in a better stripping effect.
