Description

Technical Field

[0001] This utility model relates to the field of enameled wire processing technology, specifically to a clamping device for stripping enameled wire. Background Technology

[0002] In the modern electronics and electrical field, enameled wire, as a key conductive material, is widely used in the winding fabrication of various electrical equipment such as motors, transformers, and inductors. With the booming development of these industries, the requirements for the precision, efficiency, and quality stability of enameled wire stripping processes are becoming increasingly stringent.

[0003] With the acceleration of industrialization, automated production lines have been widely used in the electronics and electrical manufacturing industry, and wire stripping operations have also entered the automation stage. At this time, wire stripping clamping devices emerged. Early automated clamping devices were mostly simple mechanical structures, using fixed jaws and screws to adjust the clamping force. Although they achieved a certain degree of automation, their shortcomings became apparent when facing complex and ever-changing production demands. For example, when it was necessary to frequently change to different diameters and materials of enameled wire during production, these fixed clamping devices required a significant amount of time for adjustment, leading to prolonged production line downtime and a substantial reduction in production efficiency.

[0004] According to the patent application CN217182623U, "This utility model relates to the field of enameled wire clamping technology and discloses an anti-wear clamping fixture for enameled wire stripping. It includes a base plate, a frame fixedly connected to the top of the base plate, a square groove at the top of the frame, and a sliding connection to the inner wall of the square groove. A concave plate is fixedly connected to the left end, and a push rod is slidably connected to the through hole at the middle of the left end of the concave plate. In this utility model, the coarse enameled wire is placed inside the left clamping block. The motor is started, causing the gears to move. The right clamping block moves to the left under the action of the connecting block, thus clamping the coarse enameled wire. This solves the problem of time-consuming and laborious manual clamping by traditional workers. Workers pull the push plate outwards, and the push rod moves the squeezing plate and suction cup outwards. By pushing the slider, the clamping device can be adjusted left and right, coordinating with the stripping device to keep the enameled wire on the same horizontal line."

[0005] Regarding the aforementioned related technologies, the inventors believe that the device has limitations in clamping enameled wires of different diameters. Furthermore, to clean the surface of the enameled wire, it's crucial to avoid contamination, which typically includes solid particulate impurities such as dust and metal shavings. When the wire stripping tool contacts the wire for stripping, these particles act like abrasives, accelerating tool wear. Therefore, there is an urgent need to improve the wire stripping clamping device to solve these problems. Utility Model Content

[0024] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Existing technologies suffer from the inability to adjust the clamping mechanism according to different wire diameters. When frequent changes to different wire diameters and materials are required, this fixed clamping device necessitates significant time-consuming adjustments, leading to prolonged production line downtime and a substantial reduction in production efficiency. Please refer to [link to relevant documentation]. Figures 1-4 This utility model provides a technical solution: a clamping device for stripping enameled wire, including a base plate 1, characterized in that: a mounting frame 2 is fixedly installed on the base plate 1, a transmission device 3 is fixedly installed on the mounting frame 2, a cleaning device 4 is fixedly installed on the side of the mounting frame 2, and a clamping device 6 is movably installed below the mounting frame 2.

[0027] The wire stripping clamping device includes a clamping mechanism, a transmission mechanism, and a cleaning mechanism. The clamping mechanism includes a mounting frame 2, a slide groove 5 in the middle of the mounting frame 2, a slider 201 movably mounted in the slide groove 5, and a threaded groove 202 on the slider 201.

[0028] The lower end of the slider 201 has a slot 207 in the middle. A slot plate 203 is movably installed in the slot 207. Limiting blocks 204 are provided on the upper and lower sides of the slot plate 203. Multiple fixed shafts 205 are provided in the slot plate 203. Rollers 206 are movably installed on the fixed shafts 205. Rubber pads are fixedly installed on the rollers 206.

[0029] The upper and lower sides of the slot 207 are provided with limiting slots 208, and the side of the slot 207 is provided with an installation slot 209. A spring 210 is fixedly installed in the installation slot 209, and the other end of the spring 210 is fixedly installed on the back of the slot plate 203.

[0030] The transmission mechanism includes a mounting bracket 2 and a slide 5. A motor 301 is fixedly mounted on the mounting bracket 2. A pulley 302 is fixedly mounted on the output shaft of the motor 301. A screw 304 is movably mounted in the slide 5. The screw 304 is a bidirectional screw. A driven wheel is fixedly mounted on the right end of the screw 304. The pulley 302 and the driven wheel are connected by a belt 303. The slider 201 is movably mounted on the screw 304 by a thread.

[0031] The enameled wire with the processing strip is placed between the sliders 201. The motor 301 is started, causing the sliders 201 to move inward in the groove 5 under the action of the screw 304. As the sliders 201 move closer, the enameled wire abuts against the roller 206, thereby pushing the groove plate 203 to move. When the back of the groove plate 203 abuts against the pressure sensor, and when the data received by the pressure sensor reaches the preset data, a stop signal is sent to the motor 301, causing the motor 301 to stop.

[0032] Example 2:

[0033] Based on Example 1, please refer to Figures 4-6 After the enameled wire is coated, there is dirt on the surface of the wire. This dirt will affect the subsequent wire stripping process. Therefore, this device is also equipped with a cleaning mechanism. The cleaning mechanism includes a mounting frame 2. A mounting base plate 305 is fixedly installed on the side of the mounting frame 2. A motor 306 is fixedly installed on the mounting base plate 305. A pulley 307 is fixedly installed on the output shaft of the motor 306. A slot 309 is provided on the mounting base plate 305.

[0034] A protective cover 312 is fixedly installed below the mounting base plate 305. A connector 406 is fixedly installed inside the protective cover 312. A bearing 405 is fixedly installed on the connector 406. A cleaning roller 311 is fixedly installed on the outer ring of the bearing 405. The cleaning roller 311 is provided with an arc groove 310. The pulley 307 and the arc groove 310 are connected by a belt 308.

[0035] The cleaning roller 311 is provided with multiple sets of grooves 404, the protective cover 312 is provided with a liquid injection pipe 401, the liquid injection pipe 401 passes through the protective cover 312 and is fixedly installed on the horizontal pipe 402, the horizontal pipe 402 is provided with multiple sets of liquid outlet holes 403, the side of the protective cover 312 is provided with a wiping sponge 407, and multiple sets of cleaning scrapers 408 are fixedly installed inside the cleaning roller 311. A cleaning brush is fixedly installed at the end of the cleaning scraper 408, and anti-fouling plates 409 are provided at both ends of the cleaning scraper 408.

[0036] The enameled wire is passed through the cleaning roller 311. At this time, the motor 306 is started, and a special cleaning agent is injected into the horizontal tube 402 through the injection pipe 401. The cleaning roller 311 is driven to rotate through the belt drive, which in turn drives the internal cleaning scraper 408 to rotate. The cleaning agent dripping through the outlet hole 403 falls onto the enameled wire through the groove 404, dissolving the dirt on the enameled wire and making it easier for the brush to clean the dirt. At the same time, the anti-fouling plates 409 designed at both ends of the cleaning scraper 408 can effectively prevent the dirt under cleaning from affecting the bearing. Meanwhile, when the enameled wire passes through the wiping sponge 407, its surface will be cleaned a second time, improving the cleaning effect.
