Description

Technical Field

[0001] This invention relates to the field of flat wire winding equipment technology, specifically a high-efficiency, non-destructive flat wire positioning and winding machine. Background Technology

[0002] Flat wire (such as flat copper wire) is widely used in the windings of electromagnetic components such as transformers, inductors, and motor coils. During the winding process, the flat wire needs to be wound onto the coil frame or positioning mold according to the set number of turns and arrangement.

[0003] However, in existing winding equipment, the flat wire directly contacts the upper surface of the positioning table during the winding process. As the winding action proceeds, continuous sliding friction occurs between the lower surface of the flat wire and the upper surface of the positioning table. This sliding friction can easily cause scratches and wear on the insulation layer or copper layer on the surface of the flat wire, thereby affecting the electrical performance of the coil and the product quality. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency, non-destructive flat wire positioning and winding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0015] Furthermore, the winding mechanism includes a motor fixedly connected to the top front side of the lifting platform, a mounting base fixedly connected to the output shaft end of the motor, and a positioning column fixedly connected to the middle of the bottom end of the mounting base. A winding head is detachably connected to the bottom end of the mounting base and near the side wall of the positioning column. A wire routing boss is integrally formed at the bottom end of the winding head.

[0016] Furthermore, an arc-shaped locking block is fixedly connected to one top side of the winding head, and an arc-shaped locking groove matching the arc-shaped locking block is provided on one bottom side of the mounting base.

A rotating shaft 18 is fixedly connected to the end of the connecting rod 16 away from the elongated hole 17. The end of the rotating shaft 18 is rotatably connected to the mounting frame 2 via a bearing. Mounting frame 3 is fixedly connected to the top of the workbench 1 and to the adjacent side of mounting frame 2. A winding mechanism is vertically adjustable on the front side of mounting frame 3. A mounting plate 19 is fixedly connected to the middle of the front side of mounting frame 3. Linear guide rails 20 are fixedly connected to both ends of the front side of mounting plate 19. Slide seats 21 are slidably fitted on both linear guide rails 20. A lifting platform 22 is fixedly connected between the front sides of the two slide seats 21. A crossbeam 23 is fixedly connected to the front top of mounting frame 3. The top of the crossbeam 23 is fixedly connected to an electric push rod 24. The output shaft of the electric push rod 24 is fixedly connected to the rear top of the lifting platform 22. The winding mechanism includes a motor 25 fixedly connected to the front top of the lifting platform 22, a mounting base 26 fixedly connected to the output shaft end of the motor 25, and a positioning column 27 fixedly connected to the middle of the bottom end of the mounting base 26. A winding head 28 is detachably connected to the bottom end of the mounting base 26 and the side wall near the positioning column 27. A wire guide boss is integrally formed at the bottom end of the winding head 28. An arc-shaped locking block 29 is fixedly connected to one side top of the winding head 28. An arc-shaped slot 30 matching the arc-shaped locking block 29 is opened on one side bottom of the mounting base 26.The base 4 is fixedly connected to the top center of the workbench 1. The top of the base 4 is detachably equipped with a positioning mechanism. The positioning mechanism includes a positioning platform 31 detachably mounted on the top of the base 4, a rod 32 fixedly connected to the bottom of the positioning platform 31, a hole 33 opened in the middle of the top of the base 4 and matching the rod 32, and a threaded hole 34 opened on one radial side of the base 4. The positioning platform 31 and the baffle 35 are provided with through holes corresponding to the threaded hole 34. The positioning platform 31 is fixed on the base 4 by passing a bolt through the through hole and screwing it into the threaded hole 34. The positioning mechanism also includes a circular groove 37 opened on the top of the positioning platform 31 near the rod 32, a positioning sleeve 38 rotatably mounted in the circular groove 37, and a connecting shaft 39 fixedly connected to the middle of the bottom of the positioning sleeve 38. The connecting shaft 39 is rotatably engaged with the circular groove 37 through a bearing. The middle of the top of the positioning sleeve 38 is provided with a positioning hole matching the positioning post 27.

[0032] In this embodiment, the positioning sleeve 38, connecting shaft 39 and circular groove 37 are used in combination to enable the positioning sleeve 38 to rotate synchronously during the winding process of the flat wire. This transforms the sliding friction between the lower surface of the flat wire and the positioning platform 31 into rolling following between the lower surface of the flat wire and the positioning sleeve 38, thereby avoiding relative sliding and effectively preventing scratches on the surface of the copper wire.

[0033] By using the electric push rod 15, connecting rod 16, rotating shaft 18, elongated hole 17 and drive rod 14 together, the lever-type vertical lifting and cutting of the cutting blade 12 is realized. The thrust of the electric push rod 15 is converted into a stable and controllable cutting action of the cutting blade 12 by lever transmission. Compared with the direct drive method, this structure can obtain a greater cutting force under the same stroke, and the cutting action is more stable, avoiding deformation of the flat wire end or uneven cut due to insufficient cutting force or unstable cutting.

[0034] All electrical components mentioned in this solution are existing technologies, and each model is only one of them. Any electrical component that meets the requirements of this solution can be used. Those skilled in the art should connect all electrical components and their compatible power supplies via wires. A suitable controller should be selected based on the actual situation to meet control requirements. The specific connections and control sequence should refer to the working principle described below, where the electrical connections are completed according to the sequential operation of each electrical component. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0035] Working principle: During operation, the external wire feeding component conveys the flat wire to the feeding table 7. After being guided by the roller 36 between the roller 36 and the feeding table 7, the flat wire continues to move forward to the positioning table 31, with its end protruding outwards. At the same time, one side of the flat wire is placed against the baffle 35. Subsequently, the electric push rod 24 drives the lifting table 22 to descend along the linear guide rail 20, causing the positioning pin 27 to insert into the positioning hole at the top of the positioning sleeve 38. At this time, the end of the flat wire is located between the baffle 35 and the positioning pin 27. The side wall of the cable guide boss at the bottom of the wire end 28 abuts against the side edge of the flat wire end; the starting motor 25 drives the mounting base 26 to rotate, and the mounting base 26 drives the winding head 28 to rotate through the cooperation of the arc-shaped slot 30 and the arc-shaped block 29. The side wall of the cable guide boss drives the end of the flat wire to rotate around the positioning post 27 through lateral thrust, so that the flat wire is gradually wound onto the positioning sleeve 38. As the number of winding layers increases, the electric push rod 24 drives the lifting platform 22 to move the mounting base 26, the positioning post 27 and the winding wire. The head 28 is raised synchronously and gradually to keep the wire guide boss at a suitable winding height. During the winding process, the lower surface of the flat wire contacts the positioning sleeve 38 and drives the positioning sleeve 38 to rotate synchronously in the circular groove 37 through the connecting shaft 39. This transforms the sliding friction in the traditional solution into rolling following, avoiding relative sliding friction between the lower surface of the flat wire and the positioning platform 31, and effectively preventing scratches on the copper wire. After one coil is wound, the electric push rod 15 pushes one end of the connecting rod 16, which rotates around the rotating shaft 18. The elongated hole 17 at the other end of the connecting rod 16 drives the drive rod 14 to rise and fall vertically. The drive rod 14 drives the lifting platform 11 to slide down the linear guide rail 9 through the vertical plate 13, so that the cutting blade 12 cuts the flat wire. Then, the electric push rod 24 drives the winding head 28 and the positioning post 27 to rise. The external wire feeding component continues to feed the flat wire, so that the new end of the flat wire moves again between the baffle 35 and the positioning post 27, and the winding process of the next coil can begin.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
