Description

Technical Field

[0001] This utility model relates to the field of resistance wire winding technology, and in particular to a resistance wire winding device. Background Technology

[0002] A resistance wire winding device is a specialized piece of equipment used to wind resistance wires (such as nickel-chromium alloy wire, constantan wire, etc.) onto an insulating frame or mandrel according to a specific pattern. It is used in the manufacture of electronic components such as resistors, heating elements, and sensors (such as thermistors). Its core function is to control the winding spacing, tension, and number of turns to ensure the accuracy and consistency of the resistance value.

[0003] In existing technologies, conventional resistance wire winding devices typically only achieve the winding effect of the resistance wire. After winding, the wire is removed and then welded and fixed. However, this process can easily cause the resistance wire to loosen. It is impossible to directly weld and fix the resistance wire to the insulating frame during the winding process. Once the resistance wire loosens, it needs to be rewound, which reduces the efficiency of resistance wire winding processing. Utility Model Content

[0004] In view of this, the present invention provides a resistance wire winding device, the main technical problem to be solved is: the resistance wire can be wound on the insulating frame while being welded and fixed to the insulating frame.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a resistance wire winding device, including a base, a clamping and rotating assembly installed inside the base, a welding assembly installed inside the base, the welding assembly including a movable seat, the movable seat being slidably connected inside the base, a motor three fixedly connected to the upper surface of the movable seat, a bidirectional lead screw two fixedly connected to the output end of the motor three, the bidirectional lead screw two being rotatably connected inside the movable seat, a limit block fixedly connected inside the movable seat, and a sliding plate one slidably connected inside the movable seat. A sliding plate is provided. Sliding plate one and sliding plate two are threadedly connected inside a double-acting screw two. A welding device is installed on the lower surface of sliding plate one. A support plate is fixedly connected to the upper surface of sliding plate two. A side plate is fixedly connected to the upper surface of the movable seat. A cylinder one is fixedly connected to the outer wall of the side plate. A placement seat is fixedly connected to the telescopic end of cylinder one. A clamping plate is installed inside the placement seat. A cylinder two is fixedly connected to the inside of the base. A sliding rod is fixedly connected to the inside of the base. The telescopic end of cylinder two is fixedly connected to the outer wall of the movable seat. The sliding rod is slidably connected inside the movable seat.

[0006] By adopting the above technical solution, the insulating frame is clamped and rotated by the clamping and rotating assembly. The starting motor three drives the bidirectional lead screw two to rotate, causing the sliding plates one and two to slide in the center. This, in turn, moves the welder and the support plate closer to the insulating frame, welding one end of the resistance wire held by the placement seat and the clamping plate to one end of the insulating frame. Then, the starting motor three drives the bidirectional lead screw two to rotate, causing the sliding plates one and two to reset. The moving seat is moved by the cylinder two. Combined with the clamping and rotating assembly clamping and rotating the insulating frame, the resistance wire is wound around the outer wall of the insulating frame. When the movement reaches the moving distance, the welder reaches the other end of the insulating frame. At this time, the starting motor three drives the bidirectional lead screw two to rotate, causing the welder to move down and weld the resistance wire part at the other end of the insulating frame. Then, the starting cylinder one drives the placement seat to slide, breaking the resistance wire. This achieves the simultaneous winding and welding of the resistance wire onto the insulating frame.

[0007] As a further description of the above technical solution: the clamping and rotating assembly includes a motor, the main body of which is fixedly connected to the outer wall of the base, and the output end of which is fixedly connected to a bidirectional lead screw, which is rotatably connected to the inside of the base.

[0008] By adopting the above technical solution, the motor drives the bidirectional lead screw to rotate within the base.

[0009] As a further description of the above technical solution: the base has two clamping seats that are slidably connected inside, the two clamping seats are symmetrically arranged inside the base, and the two clamping seats are threadedly connected to the outer wall of the bidirectional lead screw.

[0010] By adopting the above technical solution, the rotation of the bidirectional lead screw causes the two clamping seats to slide in the center, thereby achieving the clamping effect on the insulating frame.

[0011] As a further description of the above technical solution: the clamping seat is rotatably connected to a rotating shaft inside, and a second motor is fixedly connected to the outer wall of one of the clamping seats. The output end of the second motor is fixedly connected to the corresponding outer wall of the rotating shaft, and a limit plate is fixedly connected to the upper surface of the clamping seat.

[0012] By adopting the above technical solution, the movement of the clamping seat drives the rotating shaft to move, and the rotating shaft clamps the outer wall of the insulating frame. Then, the second motor drives one of the rotating shafts to rotate, causing both rotating shafts to rotate and drive the insulating frame to rotate, thus helping to achieve the effect of winding the resistance wire.

[0013] As a further description of the above technical solution: a roller assembly is installed inside the base, the roller assembly includes a mounting plate, and the mounting plate is fixedly connected to the upper surface of the base.

[0014] By adopting the above technical solution, the mounting plate is used to install the auxiliary roller shaft.

[0015] As a further description of the above technical solution: the base has a second mounting plate that is slidably connected inside, and the mounting plate and the second mounting plate are movably connected inside each other. The mounting plate and the second mounting plate are fixedly connected by bolts and nuts.

[0016] By adopting the above technical solution, the roller shaft is placed inside the first mounting plate, and then the second mounting plate is placed inside the base and aligned with the roller shaft. The first mounting plate and the second mounting plate are fixed with bolts and nuts to achieve clamping and limiting of the roller shaft, thus facilitating the disassembly and replacement of the roller shaft.

[0017] By employing the above technical solution, the resistance wire winding device of this utility model has at least the following beneficial effects:

[0018] 1. Compared with the prior art, this resistance wire winding device, through the setting of a moving seat, a third motor, a second bidirectional lead screw, a first sliding plate, a welder, a second sliding plate, a support plate, a first cylinder, a placement seat, a clamping plate, and a second cylinder, when it is necessary to wind and weld the resistance wire, the third motor drives the second bidirectional lead screw to rotate, causing the first and second sliding plates to slide in the center, so that the welding section of the welder and the support plate are placed on the upper and lower outer walls of the insulating frame. The welder welds one end of the resistance wire to one end of the insulating frame. Then, the second cylinder drives the moving seat to move, causing the welder to move to the other end of the insulating frame. At this time, the resistance wire is clamped by the placement seat and the clamping plate and moves. Combined with the clamping and rotating assembly, it drives the rotation of the insulating frame to realize the winding of the resistance wire. Then, the third motor drives the second bidirectional lead screw to rotate, causing the welder to contact the upper outer wall of the insulating frame again, welding the wound resistance wire to the other end of the insulating frame. At the same time, the first cylinder is started to drive the placement seat to move, pulling off the welded resistance wire, thus realizing that the resistance wire can be welded and fixed to the outer wall of the insulating frame while being wound around it.

The moving seat 301 is limited to slide on the outer wall of the slide rod 314.

[0027] The clamping and rotating assembly 2 includes a motor 201. The main body of the motor 201 is fixedly connected to the outer wall of the base 1. A bidirectional lead screw 202 is fixedly connected to the output end of the motor 201.

[0028] Working principle: When winding the resistance wire, first place the roller 402 with the resistance wire wound inside the mounting plate 401. Then, use the mounting plate 403 to clamp the roller 402 on the other side of its outer wall and secure the mounting plates 401 and 403 together with bolts and nuts. Next, place one end of the resistance wire inside the placement base 311. Place the clamping plate 312 on the outer wall of the placement base 311 and secure it with bolts and nuts, clamping one end of the resistance wire inside the placement base 311 and clamping plate 312, with one end of the resistance wire extending a certain distance. Finally, place the insulating frame on the two clamping seats 2. Inside the rotating shaft 204 of component 03, the starting motor 201 drives the bidirectional lead screw 202 to rotate, causing the two clamping seats 203 to move in alignment, which in turn moves the rotating shaft 204 to clamp and limit the insulating frame. At this time, the resistance wire, which extends a certain distance, is placed at one end of the insulating frame. The starting motor 302 drives the bidirectional lead screw 303 to rotate, causing the sliding plates 305 and 307 to slide in alignment and move the welder 306 to be placed above the insulating frame at the resistance wire, so that one end of the resistance wire is attached to one end of the insulating frame. The support plate 308 is placed below the insulating frame and attached to the outer wall of the insulating frame. The welding machine 306 then applies the resistance wire to the insulating frame. One end of the resistance wire is welded and fixed to one end of the insulating frame. Then, motor 302 drives the bidirectional lead screw 303 to rotate, causing slide plates 305 and 307 to reset, and causing the welder 306 and the support plate 308 to move away from the insulating frame. Then, motor 205 is started to drive one of the rotating shafts 204 to rotate, causing the insulating frame to be driven to rotate. At the same time, cylinder 313 is started to move the moving seat 301, which in turn moves the placement seat 311 and the clamping plate 312. At this time, the resistance wire is pulled and wrapped around the outer wall of the insulating frame. When the moving seat 301 moves to a certain distance, the welder 306 and the support plate 308 also move. Move to the other end of the insulating frame. At this time, start motor 302 again to drive the bidirectional lead screw 303 to rotate, causing slide plate 1 305 and slide plate 2 307 to slide in the center. Welder 306 contacts the resistance wire at the other end of the insulating frame. Support plate 308 is supported under the insulating frame. Welder 306 welds the resistance wire to the other end of the insulating frame. At the same time, cylinder 1 310 starts to drive the placement seat 311 to move and pull the welded resistance wire to separate it. This realizes that while the resistance wire is being wound on the outer wall of the insulating frame, the resistance wire can also be welded to the outer wall of the insulating frame, which improves the working efficiency of resistance wire winding.
