[0002] Resistance wire is an electrical wire made of alloy wire with high resistance.

[0003] In the existing technology, the winding of resistance wire is partly done manually, which is inefficient and can easily cut the hands. The other part uses auxiliary tools, but still requires manual feeding of the wire, which is very inconvenient. Therefore, a wire feeding mechanism for winding is needed. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A wire feeding mechanism for winding includes: a machine base, wherein a sliding seat, a guide wheel assembly disposed on the sliding seat, and a guide nozzle disposed on the sliding seat are provided on the machine base, and the guide wheel assembly and the guide nozzle are respectively disposed on both sides of the sliding seat;

[0007] The guide wheel assembly includes two guide wheels arranged side by side in a horizontal direction. The guide nozzle has a guide hole inside, and the outlet of the guide nozzle faces the workpiece fixing mechanism.

[0008] Its further feature is that,

[0009] It also includes a first linear module, on which the sliding seat is disposed, and the first linear module is used to drive the sliding seat to move laterally.

[0010] The first linear module includes a first slide rail, a lead screw, and a first driving component. The sliding seat is disposed on the first slide rail, and a connecting component is disposed at the bottom of the sliding seat. The connecting component is sleeved on the lead screw and threadedly connected to the lead screw. The first driving component is used to drive the lead screw to rotate.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] refer to Figure 1-2 The wire feeding mechanism for winding shown includes a machine base, a sliding seat 31 mounted on the machine base, a guide wheel assembly mounted on the sliding seat 31, and a guide nozzle 32 mounted on the sliding seat 31. The guide wheel assembly and the guide nozzle 32 are respectively mounted on both sides of the sliding seat 31. The guide wheel assembly includes two guide wheels 33 arranged side by side in the horizontal direction. The guide nozzle 32 is provided with a guide hole, and the wire outlet of the guide nozzle 32 faces the workpiece side. In use, the resistance wire from the coil passes through the two guide wheels 33 and the guide nozzle 32 in sequence. Since the guide nozzle 32 faces the workpiece side, the feeding and guiding of the resistance wire is completed. In order to limit the resistance wire, the two guide wheels 33 are provided with limit grooves on their circumferential sides, so that the resistance wire is limited within the two limit grooves.

[0028] like Figure 1 and Figure 2As shown, since the resistance wire is generally spirally wound on the workpiece, it is necessary to make the guide nozzle 32 move along the spiral direction during the winding process. To achieve this, the feeding mechanism 3 also includes a first linear module. The sliding seat 31 is disposed on the first linear module. The first linear module is used to drive the sliding seat 31 to move laterally (in the same direction as the winding of the resistance wire). The first linear module includes a first slide rail 34, a lead screw 35, and a first driving component. The sliding seat 31 is disposed on the first slide rail 34. A connecting component is provided at the bottom of the sliding seat 31. The connecting component is sleeved on the lead screw 35 and threadedly connected to the lead screw 35. The first driving component is used to drive the lead screw 35 to rotate (the first driving component can be a first motor, and the output end of the first motor is connected to...). (The lead screw is coaxially connected). Thus, the first driving member drives the lead screw 35 to rotate, causing the connecting part threaded to the lead screw 35 to move linearly, causing the sliding seat 31 to move along the extension direction of the first slide rail 34, thereby achieving the purpose of causing the guide nozzle 32 to move laterally, so that the resistance wire on the workpiece is wound evenly. In order to detect the movement of the sliding seat 31, several slotted optocouplers 38 are set on one side of the first slide rail 34. The sliding seat 31 is provided with photoelectric baffles 39 adapted to the slotted optocouplers 38. Three slotted optocouplers 38 can be set, respectively at the middle position and the two extreme positions of the lateral movement of the sliding seat 31. When the photoelectric baffle 39 is placed at the corresponding slotted optocoupler 38, the position of the sliding seat 31 can be known, and the next instruction can be issued in time.

[0029] like Figure 1 and Figure 2 As shown, in order to adapt to different workpiece windings and facilitate the cutting of resistance wires, the feeding mechanism 3 also includes a platform 36 and a first cylinder 37. The platform 36 is slidably mounted on the sliding seat 31. The first cylinder 37 is used to drive the platform 36 closer to or away from the workpiece. The guide nozzle 32 is mounted on the platform 36. Thus, by driving the platform 36 closer to or away from the workpiece through the first cylinder 37, if the workpiece width is large or the resistance wire needs to be cut, the guide nozzle 32 moves away from the workpiece to avoid interfering with the rotation of the workpiece or to facilitate the cutting mechanism 4 to cut the resistance wire.

[0030] like Figure 1 and Figure 2 As shown, the wire cutting mechanism 4 includes a pneumatic scissors 41 and a second driving member. The pneumatic scissors 41 are suspended above the guide nozzle 32, with the cutting opening of the pneumatic scissors 41 facing downwards. The second driving member is used to drive the pneumatic scissors 41 to perform lifting and lowering movements. Thus, during cutting, the pneumatic scissors 41 are driven downwards by the second driving member. When the resistance wire is placed inside the cutting opening, the pneumatic scissors 41 performs work to cut the resistance wire. After cutting is completed, the pneumatic scissors 41 returns to its original position to avoid interfering with the winding of the workpiece.

[0031] Further optimizations include, for example Figure 1 and Figure 2As shown, to prevent the free end of the resistance wire from retracting after cutting, which would require re-threading into the guide nozzle 32 when winding the next workpiece, this embodiment also includes a clamping mechanism 7 for fixing the resistance wire. Specifically, it includes a pressure head 71 and a second cylinder 72. The pressure head 71 is positioned above the platform 36, and the second cylinder 72 is positioned on the platform 36 to drive the pressure head 71 to move up and down. When cutting the wire, the second cylinder 72 drives the pressure head 71 to move downward, cooperating with the platform 36 to clamp the resistance wire, preventing it from retracting after being cut and detaching from the guide nozzle 32.

[0032] The working principle of this utility model is as follows: When in use, the resistance wire from the coil passes through the space between the two guide wheels 33 and the guide nozzle 32 in sequence. Since the guide nozzle 32 faces one side of the workpiece, the feeding and guiding of the resistance wire is completed.

[0033] This application also includes a wire cutting mechanism. During cutting, the pneumatic scissors 41 are driven downward by the second driving component. When the resistance wire is placed inside the cutting opening, the pneumatic scissors 41 performs work to cut the resistance wire. After cutting, the pneumatic scissors 41 resets to avoid interfering with the winding of the workpiece.

[0034] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
