Description

Technical Field

[0001] This utility model relates to a brushing device, specifically a flexible shaft automatic brushing device, belonging to the field of flexible shaft brushing technology. Background Technology

[0002] Automotive flexible shafts are a key flexible transmission component in automobiles, capable of transmitting torque and achieving long-distance transmission in a bent state. They are widely used in systems such as transmissions, seat adjustments, and sunroof controls. Their core function is to efficiently transmit rotational motion or torque in non-linear layouts or transmission paths that require bending. Electric sunroofs transmit motor torque through flexible shafts to drive the opening and closing of the sunroof glass. Generally, the surface of the flexible shafts used in sunroofs is covered with a textured surface.

[0003] However, during the production of car sunroof flexible shafts, the ends of the flexible shafts need to be de-linted. De-linting is generally done by feeding the material through a stepping device. After positioning, the material is conveyed to the inside of the brushing assembly, where a brush cleans the lint off the surface of the flexible shaft. However, brush cleaning alone is not enough to completely remove the lint from the flexible shaft, as the lint adheres tightly to the shaft. It takes a long time to completely remove the lint, which is a waste of time. Utility Model Content

[0004] The purpose of this invention is to provide an automatic brushing device for flexible shafts to solve the above problems. By installing a heating component near the steel wool brush, the wool on the flexible shaft is heated and melted by blowing air during brushing, so as to achieve thorough cleaning of the wool without wear on the flexible shaft.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a flexible shaft automatic brushing device includes a base plate, on which a brushing mechanism is mounted. The brushing mechanism includes a support plate, a motor, and a steel wool brush. The support plate is fixedly connected to the base plate, and a motor is mounted on one side of the support plate. The output end of the motor is key-connected to the steel wool brush. A heating mechanism is mounted on the support plate and the base plate. The heating mechanism includes a mounting base, on which a heating element is mounted. An air inlet pipe is connected to one end of the heating element, and an exhaust pipe is mounted to the other end of the heating element. A positioning seat is mounted on the support plate, and a nozzle is provided on the positioning seat. The nozzle is connected to the exhaust pipe. A guide mechanism is mounted on the support plate.

[0006] Preferably, the positioning seat and the steel wool brush are arranged opposite to each other, and the positioning seat and the nozzle are slidably connected.

[0007] Preferably, the brushing mechanism further includes a feed inlet, which is located at the center of the surface of the support plate and between the positioning seat and the steel wool brush.

[0008] Preferably, the brushing mechanism further includes a slide rail, the side of the support plate is equipped with a slide rail with a bottom opening, a slide frame is slidably connected to the slide rail, the motor is mounted on the slide frame, and a lead screw is threadedly connected to the slide rail and rotatably connected to the slide frame. The slide rail is located on the right side of the feed inlet.

[0009] Preferably, the width of the steel wool brush is smaller than the length of the nozzle, and the nozzle has holes evenly spaced on its side.

[0010] Preferably, the guiding mechanism includes two slides. The outer side of the support plate has two slides with a convex cross-section horizontally symmetrically opened about the feed inlet. The slides are slidably connected to sliders inside each of the two slides. The side of the support plate is equipped with two fixing plates opposite to the feed inlet. Each of the fixing plates is threaded with a screw that is rotatably connected to the slider. Rollers are rotatably connected to each of the two sliders.

[0011] Preferably, the guiding mechanism further includes an inner groove, and the support plate has a vertically formed inner groove that communicates with the feed inlet. A cylinder is installed at the top center of the support plate, and the telescopic end of the cylinder is fixedly connected to a pressure plate with an arc-shaped structure that is slidably connected to the inner groove.

[0012] Preferably, the guiding mechanism further includes a rubber pad, and the bottom of the pressure plate is bonded with a rubber pad.

[0013] Preferably, a collection mechanism is installed on the side of the support plate. The collection mechanism includes two sets of fixed columns. The side wall of the support plate is fixedly connected to the two sets of fixed columns. A collection hopper is placed between the two sets of fixed columns in the same set. One of the collection hoppers is located at the bottom of the feed inlet. The side of the collection hopper is flush with the side of the slide rail.

[0014] Preferably, the collection mechanism further includes a guide plate, which is obliquely welded to the side of the support plate. One end of the guide plate is located at the bottom opening of the slide rail, and the other end of the guide plate extends to the top of another collection hopper.

[0015] The beneficial effects of this utility model are as follows: The flexible shaft enters the feed port on the side wall of the support plate, waiting for the brushing process. After determining the brushing length, the flexible shaft can be pressed and fixed by the guide mechanism. At this time, the part of the flexible shaft to be brushed comes into contact with the steel wool brush. The heating element located on the base plate is activated. After the heating element heats up, the air inlet pipe is activated, allowing gas to enter the interior of the heating element from the air inlet pipe. After the gas is heated, it is discharged from the exhaust pipe and finally sprayed out from the nozzle inside the positioning seat. This achieves the heating of the flexible shaft that needs brushing. After the fibers on the flexible shaft are melted by the high-temperature hot gas, the motor is activated to make the steel wool brush rotate and clean the melted fibers on the flexible shaft. This avoids the problem of incomplete and incomplete cleaning by relying solely on the steel wool brush, saving time. Attached Figure Description

A heating element 502 is mounted on the mounting base 501. An air inlet pipe 503 is connected to one end of the heating element 502. An exhaust pipe 504 is mounted to the other end of the heating element 502. A positioning seat 505 is mounted on the support plate 201. A nozzle 506 is provided on the positioning seat 505. The nozzle 506 is connected to the exhaust pipe 504. A guide mechanism 3 is mounted on the support plate 201.

[0024] As a technical optimization of this utility model, the positioning seat 505 and the steel wool brush 207 are arranged opposite to each other, and the positioning seat 505 and the nozzle 506 are slidably connected, so as to realize the symmetry between the nozzle 506 and the flexible shaft, and facilitate the adjustment of the position of the nozzle 506.

[0025] As a technical optimization of this utility model, the brushing mechanism 2 further includes a feed inlet 202. The feed inlet 202 is provided at the center of the surface of the support plate 201. The feed inlet 202 is located between the positioning seat 505 and the steel wool brush 207, so that the flexible shaft is tangent to the flexible shaft inside the feed inlet 202, and so that the wool fibers can fully contact the steel wool brush 207.

[0026] As a technical optimization of this utility model, the brushing mechanism 2 further includes a slide rail 203. The slide rail 203 with a bottom opening is installed on the side of the support plate 201. A slide frame 204 is slidably connected to the slide rail 203. The motor 206 is installed on the slide frame 204. A lead screw 205 that is rotatably connected to the slide frame 204 is threaded onto the slide rail 203. The slide rail 203 is located on the right side of the feed inlet 202, so as to realize the adjustment of the steel wool brush 207 and select the length of the lint to be cleaned without moving the flexible shaft.

[0027] As a technical optimization of this utility model, the width of the steel wool brush 207 is smaller than the length of the nozzle 506, and the nozzle 506 has holes at equal intervals on its side to achieve comprehensive heating and melting of the wool at the end of the flexible shaft.

[0028] As a technical optimization of this utility model, the guiding mechanism 3 includes two sliding grooves 302. The outer side of the support plate 201 is symmetrically and horizontally opened with two sliding grooves 302 with a convex cross-section about the feed port 202. The sliding grooves 302 are slidably connected to the inside of each sliding groove 302. The side of the support plate 201 is equipped with two fixing plates 303 opposite to the feed port 202. The fixing plates 303 are threaded with screws 306 that are rotatably connected to the sliding plates 304. The sliding plates 304 are rotatably connected with rollers 305. The flexible shaft is passed between the two rollers 305 to achieve the positioning of the flexible shaft while guiding the wire.

[0029] As a technical optimization of this utility model, the guide mechanism 3 further includes an inner groove 307. The inner groove 307, which is vertically opened inside the support plate 201 and communicates with the feed inlet 202, is provided. A cylinder 301 is installed at the top center of the support plate 201. The telescopic end of the cylinder 301 is fixedly connected to a pressure plate 308 with an arc-shaped structure that is slidably connected to the inner groove 307. Before the steel wool brush 207 cleans the wool, the cylinder 301 can be activated to make the pressure plate 308 press the flexible shaft at the feed inlet 202 to avoid the vibration of the flexible shaft affecting the cleaning.

[0030] As a technical optimization of this utility model, the guide mechanism 3 further includes a rubber pad 309. The bottom of the pressure plate 308 is bonded with a rubber pad 309 to increase the friction force of the pressure plate 308 pressing the flexible shaft.

[0031] As a technical optimization of this utility model, a collection mechanism 4 is installed on the side of the support plate 201. The collection mechanism 4 includes two sets of fixed columns 401. The side wall of the support plate 201 is fixedly connected to the two sets of fixed columns 401. A collection hopper 402 is placed between the two sets of fixed columns 401 in the same set. One of the collection hoppers 402 is located at the bottom of the feed inlet 202. The side of the collection hopper 402 is flush with the side of the slide rail 203, so as to collect the lint and debris cleaned by the steel wool brush 207.

[0032] As a technical optimization of this utility model, the collection mechanism 4 further includes a guide plate 403. The guide plate 403 is obliquely welded to the side of the support plate 201. One end of the guide plate 403 is located at the bottom opening of the slide rail 203, and the other end of the guide plate 403 extends to the top of another collection hopper 402. When cleaning lint, it will fall onto the slide rail 203. As the slide 204 moves, the debris inside the slide rail 203 can be cleaned and flow from the guide plate 403 into the inside of the collection hopper 402, thus completing the comprehensive collection of debris.

[0033] In use, the base plate 1 is first installed on the production line for flexible shafts. When brushing the surface of the flexible shaft for automotive sunroofs, the distance between the two rollers 305 is adjusted. During adjustment, the screws 306 on the two fixing plates 303 are rotated simultaneously. Since the slider 304 is slidably connected to the groove 302, the slider 304 moves within the groove 302 when the screws 306 rotate. The flexible shaft is then placed between the two rollers 305, and the rollers 305 are adjusted to abut against the flexible shaft. With a simple touch, the flexible shaft is positioned and guided. Pushing the flexible shaft causes it to enter the feed inlet 202 on the side wall of the support plate 201, where it awaits brushing. Once the brushing length is determined, the cylinder 301 is activated to lower the pressure plate 308 inside the inner groove 307. The rubber pad 309 further presses and fixes the flexible shaft. At this point, the part of the flexible shaft to be brushed contacts the steel wool brush 207. The heating element 502 located on the base plate 1 is then activated. After the heating element 502 heats up, the air inlet pipe 503 is activated, achieving air... The gas enters the heating element 502 through the air inlet pipe 503, is heated, and then exits through the exhaust pipe 504. Finally, the hot gas is sprayed out from the nozzle 506 inside the positioning seat 505, heating the flexible shaft that needs brushing. The lint on the flexible shaft is melted by the high-temperature hot gas, and the motor 206 is activated to rotate the steel wool brush 207 to clean the melted lint on the flexible shaft. This avoids the problem of incomplete or inadequate cleaning by the steel wool brush 207 alone. The cleaned debris falls into the collection hopper 402, and the slide rail 20... 3. The debris inside can be pushed to the hole at the bottom of the slide rail 203 by the sliding carriage 204 and discharged. Finally, it falls onto the guide plate 403 and enters the interior of another collection hopper 402. When cleaning the collection hopper 402, simply remove the collection hopper 402 directly from the fixed column 401. Finally, when adjusting the length of the bristle cleaning on the flexible shaft, the screw 205 can be rotated to move the carriage 204 inside the slide rail 203, thereby changing the length of contact between the steel wool brush 207 and the bristles on the flexible shaft.
