Description

Technical Field

[0001] This invention relates to the field of wire harness wrapping technology, and more particularly to an automatic wire harness wrapping device for automotive corrugated pipes. Background Technology

[0002] In modern industrial production and construction, corrugated pipes, as tubular components with annular corrugated outer walls, are widely used in industries such as the automotive industry due to their good flexibility, fatigue resistance, high and low temperature resistance, and excellent bending performance. They can effectively protect internal wiring and pipelines while adapting to various complex installation environments. In the actual application of corrugated pipes, in order to further enhance their local protective performance, it is often necessary to wrap the corrugated pipes with adhesive tape by spot wrapping. In the early days, the work of wrapping corrugated pipes with adhesive tape was mainly done manually. However, the efficiency of manual wrapping was extremely low, far from meeting the needs of large-scale production. Moreover, the quality of manual wrapping was difficult to guarantee, making it difficult to achieve consistent indicators such as the tightness, uniformity, and overlap rate of the adhesive tape. Problems such as loose wrapping and wrinkles in the adhesive tape were prone to occur, thus affecting the protective effect of the corrugated pipe. The current process of wrapping corrugated pipes with adhesive tape is usually completed using an adhesive tape wrapping machine. During the wrapping process, the corrugated pipe is manually pushed into the inside of the wrapping opening, and the brush inside the rotating drum touches the outside of the corrugated pipe. At this time, the adhesive tape is wrapped by the rotation of the rotating drum. Compared with manual wrapping, mechanical wrapping equipment improves the wrapping efficiency and consistency to a certain extent. However, the wrapping is only done by the brush, which cannot guarantee the tightness of the adhesive tape wrapping. Also, when wrapping the corrugated pipe, the adhesive tape cannot be embedded into the inside of the groove on the outside of the corrugated pipe, so that the adhesive tape only contacts the outer surface of the corrugated pipe, which further leads to the problem of loose wrapping.

Through the abutment of the convex strips on both sides of the corrugated pipe, the first piece of adhesive tape is embedded inside the groove on the outside of the corrugated pipe, improving the tightness of the winding of the first piece of adhesive tape. After the second slide plate moves away from the corrugated pipe, the corrugated pipe continues to wind the first piece of adhesive tape through the abutment of the convex strips on the side wall of the conveyor belt. The limiting and abutment of the corrugated pipe by the conveyor belt prevents the corrugated pipe from twisting, and at the same time improves the stability and efficiency of the process of winding the corrugated pipe with adhesive tape. As the second slide plate moves away from the corrugated pipe, the cutter moves downward. When the cutter abuts the first piece of adhesive tape and rotates in the direction of the moving frame, the cutter pulls the first piece of adhesive tape, making the first piece of adhesive tape taut, further improving the tightness of the winding of the corrugated pipe with the first piece of adhesive tape.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Reference Figure 1 - Figure 11 As shown, an automatic tape wrapping device for automotive corrugated pipe harnesses includes a workbench 1. A winding assembly is movably mounted on the top of the workbench 1. The winding assembly includes a movable frame 31 and a sliding frame 22. The sliding frame 22 is slidably mounted on the top of the workbench 1. Two rollers 226 are rotatably mounted on the top of the sliding frame 22. A conveyor belt 224 is movably sleeved on the outer side of the rollers 226. A working cavity 11 is fixedly mounted on the top of the workbench 1. The movable frame 31 is slidably mounted inside the working cavity 11. A sliding plate 312 is slidably mounted on the side wall of the movable frame 31. A sliding plate 313 is slidably inserted into the side wall of the sliding plate 312. The side walls of the sliding plate 313 and the conveyor belt 224 are integrally formed with several evenly distributed protrusions 225. An elliptical hole 318 is opened on the side wall of the sliding plate 313. A motor 316 is fixedly mounted inside the movable frame 31. A bidirectional lead screw 315 is fixedly connected to the output shaft of the motor 316. The bidirectional lead screw 315 is movably inserted into the inside of the elliptical hole 318.

[0032] A clamping assembly is movably installed between the conveyor belt 224 and the slide plate 312. The clamping assembly is mainly used for clamping and stretching the bellows.

[0033] In this process, after the clamping assembly clamps and stretches the bellows, the protrusion 225 and the groove on the outside of the bellows fit together.

[0034] like Figures 5-7 As shown, the clamping assembly includes a fixed frame 21, a side plate 214, and a sliding plate 23. The side plate 214 is fixedly installed on the top of the fixed frame 21, and the sliding plate 23 is slidably installed on the top of the fixed frame 21. A sliding block 211 is movably installed between the fixed frame 21 and the sliding frame 22. The top of the fixed frame 21 is integrally formed with the side plate 214. A lead screw 213 is rotatably installed on the side wall of the side plate 214. A motor 212 is fixedly installed on the side wall of the fixed frame 21. The output shaft of the motor 212 is fixedly connected to the lead screw 213. The sliding plate 23 and the lead screw 213 are threadedly connected.

[0035] The working principle of the clamping assembly is as follows: After the two ends of the corrugated pipe are manually placed on the outside of the two air bags 232, the external air pump is started and inflates the air bags 232. The air bags 232 expand and fit against the inner wall of the corrugated pipe to fix the corrugated pipe. The air bags 232 fix and clamp the corrugated pipe from the inside, preventing the corrugated pipe from deforming and improving the qualification rate of the corrugated pipe. At this time, the motor 212 starts, the lead screw 213 rotates and drives the sliding plate 23 to move away from the side plate 214, so that the sliding plate 23 pulls the corrugated pipe. At this time, the groove and the convex strip 225 on the outside of the corrugated pipe fit together. After the corrugated pipe is unfolded, the tape wrapping operation is performed.

[0036] like Figure 6 and Figure 7 As shown, a second motor 233 is fixedly installed on the side wall of the side plate 214. The output shaft of the second motor 233 is fixedly connected to a rotating rod 234. Gear 1 215 and gear 216 are rotatably installed inside the side plate 214 and the sliding plate 23. Gear 216 is slidably inserted into the outside of the rotating rod 234. Gear 1 215 and gear 216 mesh with each other. A turntable 231 is integrally formed on one side wall of gear 1 215. An airbag 232 is fixedly installed on the side wall of the turntable 231. The other side wall of gear 1 215 is fixedly connected to an external air pump through an air pipe.

[0037] like Figure 4 , Figure 5 and Figure 7 As shown, the side wall of the sliding frame 22 is provided with a second sliding groove 222, the sliding block 211 is slidably installed inside the second sliding groove 222, a spring 223 is provided between the sliding block 211 and the side wall of the second sliding groove 222, and an electric push rod 221 is fixedly installed inside the working cavity 11, and the output end of the electric push rod 221 is fixedly connected to the side wall of the sliding frame 22.

[0038] After the corrugated pipe is unfolded, the electric push rod 221 is activated and pulls the sliding frame 22, causing the sliding frame 22 to move the fixed frame 21 towards the working chamber 11. When the fixed frame 21 touches the side wall of the working chamber 11, the electric push rod 221 continues to move, and the sliding frame 22 drives the conveyor belt 224 to approach the corrugated pipe, causing the sliding block 211 to stretch the spring 223. When the conveyor belt 224 touches the corrugated pipe, the protrusion 225 is embedded in the groove on the outside of the corrugated pipe, and the electric push rod 221 closes. When the tape is wrapped, the motor 233 is activated, the rotating rod 234 rotates, and drives the turntable 231 to rotate through the gear 215 and the gear 216. The turntable 231 drives the corrugated pipe to rotate through the airbag 232. At this time, the conveyor belt 224 limits the corrugated pipe to prevent the corrugated pipe from twisting and improves the stability of the corrugated pipe during the tape wrapping process.

[0039] Further reference Figure 6 To explain, the sliding block 211 is the drive slide rail of the fixed frame 21. The bottom of the fixed frame 21 is integrally formed with a lead screw 244. The sliding block 211 is fixedly installed with a motor 241. The output shaft of the motor 241 is fixedly connected to a gear 242. The sliding block 211 is rotatably installed with a gear 243. The gear 242 and the gear 243 mesh with each other. The gear 243 is sleeved on the outside of the lead screw 244. The gear 243 and the lead screw 244 are threadedly connected. When the fixed frame 21 moves, the motor 241 starts, and the gear 242 drives the gear 243 to rotate, so that the fixed frame 21 moves.

[0040] like Figure 4 and Figure 9 As shown, a ball bearing 314 is integrally formed on the inner wall of the elliptical hole 318 near the slide plate 312. The ball bearing 314 is slidably connected to the screw groove on the side wall of the bidirectional lead screw 315. A spring 317 is provided between the slide plate 313 and the moving frame 31. The spring 317 and the slide plate 313 are slidably connected. An electric actuator 311 is fixedly installed inside the working cavity 11. The output end of the electric actuator 311 is fixedly connected to the side wall of the moving frame 31.

[0041] like Figure 2 and Figure 4 As shown, a roll of adhesive tape 111 is rotatably mounted inside the working cavity 11. Adhesive tape 112 is wound around the side wall of the roll of adhesive tape 111 and extends between the cutter 32 and the moving frame 31.

[0042] During the process of wrapping the corrugated pipe with adhesive tape, motor 4 (316) and electric actuator 2 (311) are started. Motor 4 (316) drives the double-acting screw 315 to rotate, and electric actuator 2 (311) pushes the moving frame 31 towards the corrugated pipe, causing slide plate 2 (313) to move the adhesive tape 112 towards the corrugated pipe. When the protrusion 225 on the side wall of slide plate 2 (313) abuts against the side wall of the corrugated pipe, electric actuator 2 (311) closes, the adhesive tape 112 and the corrugated pipe are in contact, slide plate 2 (313) compresses spring 2 (317) and retracts, and the protrusion 225 on the side wall of slide plate 2 (313) moves into the interior of slide plate 1 (312). At this time, the ball bearing 314 slides into the screw groove on the side wall of the double-acting screw 315, so that the double-acting screw 315 drives slide plate 2 (313) and slide plate 1 (312) to move towards the corrugated pipe. 12. Shaking is performed. The shaking of the slide plate 312 improves the tightness between the tape 112 and the corrugated tube, preventing the end of the tape 112 from not adhering to the corrugated tube. When the protrusion 225 on the side wall of the slide plate 313 corresponds to the groove on the outside of the corrugated tube, the spring 317 is released. The protrusion 225 on the side wall of the slide plate 313 is embedded in the inside of the groove on the outside of the corrugated tube. The ball bearing 314 moves away from the double-acting screw 315. At this time, the protrusion 225 embeds the tape into the inside of the groove on the outside of the corrugated tube. The motor 233 starts, the corrugated tube rotates and wraps the tape. Through the contact of the protrusions 225 on both sides of the corrugated tube, the tape 112 is embedded in the inside of the groove on the outside of the corrugated tube, further improving the tightness of the tape 112 wrapping.

[0043] like Figure 4 and Figure 10 As shown, the inner walls on both sides of the working chamber 11 are provided with sliding grooves 314. A cutter 32 is movably installed between the two sliding grooves 314. A gear 5 322 is fixedly installed on the side wall of the cutter 32. A rack 321 is fixedly installed on the side wall of the sliding groove 314. The gear 5 322 and the rack 321 mesh with each other. A rotating sleeve 327 is rotatably installed on the side wall of the cutter 32. A spring 326 is provided between the rotating sleeve 327 and the side wall of the sliding groove 314.

[0044] like Figure 4 , Figure 8 and Figure 10 As shown, the inner walls on both sides of the working chamber 11 are provided with a first groove 113, and the third groove 114 is connected to the first groove 113. A magnetic ring 325 is fixedly installed on the side wall of the cutter 32. The magnetic ring 325 is located inside the first groove 113. A support rod 323 is rotatably installed on the side wall of the moving frame 31. A magnetic sheet 324 is fixedly installed on the side wall of the support rod 323. The magnetic sheet 324 and the magnetic ring 325 are magnetically attracted to each other. A torsion spring is provided at the rotatable connection between the moving frame 31 and the support rod 323.

[0045] When the electric actuator 311 pushes the moving frame 31 towards the corrugated pipe, the support rod 323 moves along with the moving frame 31. When the protrusion 225 on the side wall of the sliding plate 313 abuts against the side wall of the corrugated pipe, the magnetic sheet 324 and the magnetic ring 325 attract each other. When the corrugated pipe rotates and wraps the adhesive tape 112, the electric actuator 311 starts and pulls the moving frame 31 away from the corrugated pipe, so that the sliding plate 313 moves away from the corrugated pipe. At this time, the corrugated pipe wraps the adhesive tape 112 by contacting the protrusion 225 on the side wall of the conveyor belt 224. During the movement of the moving frame 31, the support rod 323 pulls the cutter 32, so that the cutter 32 moves downward along the slide groove 314. When the cutter 32 abuts against the adhesive tape 112, the cutter 32 continues to move downward. At this time, the gear 5 322... Engaging with the rack 321, the cutter 32 rotates towards the moving frame 31, pulling the tape 112. This pull tightens the tape 112, further improving the tightness of the corrugated pipe winding. When the bottom of the cutter 32 contacts the sliding plate 312, the cutter cuts the tape 112. At this time, the magnetic sheet 324 moves away from the magnetic ring 325, and the cutter 32 returns to its original position via the spring 326. The support rod 323 returns to its original position via the torsion spring, and the sliding block 211 drives the fixed frame 21 to move. The corrugated pipe moves along the conveyor belt 224 via the convex strip 225. With the follow of the conveyor belt 224, the convex strip 225 continues to wind the remaining tape 112, improving the efficiency of corrugated pipe processing.

[0046] The working principle and usage of this invention are explained in detail below: After the two ends of the corrugated pipe are manually fitted onto the outside of the two air bladders 232, the air bladders 232 inflate and fit against the inner wall of the corrugated pipe to fix it. At this time, the motor 212 starts, and the lead screw 213 drives the sliding plate 23 to move away from the side plate 214. The sliding plate 23 pulls the corrugated pipe, so that the groove and the convex strip 225 on the outside of the corrugated pipe fit together. After the corrugated pipe unfolds, the electric push rod 221 pulls the sliding frame 22, so that the sliding frame 22 drives the fixed frame 21 to move towards the working chamber 11. When the fixed frame 21 touches the side wall of the working chamber 11, the electric push rod 221 continues to move, so that the conveyor belt 224 touches the corrugated pipe. At this time, the convex strip 225... When the groove is embedded on the outside of the corrugated pipe, the electric actuator 221 is closed, and the electric motor 316 and the electric actuator 311 are started. The electric motor 316 drives the bidirectional lead screw 315 to rotate, and the electric actuator 311 pushes the moving frame 31 towards the corrugated pipe, so that the support rod 323 moves with the moving frame 31. The sliding plate 313 drives the tape 112 to move towards the corrugated pipe. When the protrusion 225 on the side wall of the sliding plate 313 abuts against the side wall of the corrugated pipe, the magnetic sheet 324 and the magnetic ring 325 attract each other, the electric actuator 311 closes, the tape 112 and the corrugated pipe are in contact, the sliding plate 313 compresses the spring 317 and retracts, and the protrusion 225 on the side wall of the sliding plate 313 moves into the interior of the sliding plate 312. At this time, the bidirectional lead screw 315 drives the sliding plate 312 to move. 13 and slide plate 312 are shaken. The shaking of slide plate 312 improves the tightness between tape 112 and corrugated pipe, preventing the end of tape 112 from not adhering to the corrugated pipe. When the protrusion 225 on the side wall of slide plate 313 corresponds to the groove on the outside of the corrugated pipe, spring 217 is released. The protrusion 225 on the side wall of slide plate 313 is embedded into the inside of the groove on the outside of the corrugated pipe. At this time, the protrusion 225 embeds the tape into the inside of the groove on the outside of the corrugated pipe. Motor 233 starts, the corrugated pipe rotates and wraps the tape. Through the contact of the protrusions 225 on both sides of the corrugated pipe, the tape is embedded into the inside of the groove on the outside of the corrugated pipe, further improving the tightness of tape 112 wrapping. When the corrugated pipe is rotating and wrapping tape 112, electric actuator 2... 311 is activated and the moving frame 31 is pulled away from the corrugated pipe, causing the slide plate 313 to move away from the corrugated pipe. At this time, the corrugated pipe is wrapped with adhesive tape 112 by the contact of the protrusions 225 on the side wall of the conveyor belt 224. The conveyor belt 224 limits and contacts the corrugated pipe, preventing it from twisting and improving the stability and efficiency of the adhesive tape wrapping process. During the movement of the moving frame 31, the support rod 323 pulls the cutter 32, causing the cutter 32 to move downward along the slide groove 114. When the cutter 32 contacts the adhesive tape 112, it continues to move downward, causing the cutter 32 to rotate towards the moving frame 31. This rotation pulls the adhesive tape 112, making the adhesive tape 112 taut.To further improve the tightness of the corrugated pipe wrapping tape 112, when the bottom of the cutter 32 contacts the sliding plate 312, the cutter 32 cuts the tape 112. At this time, the magnetic sheet 324 moves away from the magnetic ring 325, the cutter 32 and the support rod 323 return to their positions, and the sliding block 211 drives the fixed frame 21 to move. Meanwhile, the corrugated pipe moves along the conveyor belt 224 via the convex strip 225. The following action of the conveyor belt 224 allows the convex strip 225 to continue wrapping the remaining tape 112, further improving the processing efficiency of the corrugated pipe.

[0047] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
