Description

Technical Field

[0001] This application relates to the field of manufacturing magnetic cores, coils or magnets, and more specifically to the field of stranded wire mechanisms with laser-fused skins. Background Technology

[0002] In the production process of a magnetic winding machine, the stranding and winding of the wire are the core processes. To meet the performance requirements of electronic components (such as inductors), the wire needs to be stranded into a specific twisted structure. For example, the utility model patent document with publication number CN202363240U describes a fully automatic magnetic winding machine. After stranding, its stranding mechanism forms a front twist between the pre-stretching fixing mechanism and the pre-stretching rotating mechanism, and a rear twist between the post-stretching rotating mechanism and the post-stretching fixing mechanism. An unstretched portion of wire is formed between the front and rear twists. The fully automatic magnetic winding machine then sequentially feeds the rear twist, the unstretched portion of wire, and the front twist to the winding mechanism. After the rear twist passes through the magnetic ring, the front twist is wound around the magnetic ring. The rear twist is removed as a tail wire, and the unstretched portion of wire serves as the lead wire outside the magnetic ring.

[0003] However, when using highly elastic wires, such as insulated coated wires, the twisted structure formed on the wires is prone to loosening during the winding process after the twisting mechanism completes the twisting. The loosened wires have larger diameters and irregular shapes, making it difficult for them to pass smoothly through the center hole of the magnetic ring. This affects the normal operation of the winding process. Even if they are forced to pass through, the wires will deform, causing problems such as loose winding and inconsistent lead lengths, which affect the stability of product quality. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes: A stranding mechanism with laser melting includes a laser emitter and a front fixing mechanism, a front wire clamp, a rotating mechanism, a rear wire clamp, and a rear fixing mechanism arranged sequentially along the copper wire traveling direction. The rotating mechanism is used to drive the front wire clamp and the rear wire clamp to rotate synchronously, and the laser emitter is used to emit a laser to melt the copper wire between the rear wire clamp and the rear fixing mechanism.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the rotating mechanism includes a driving component and a stranded tube, the two ends of the stranded tube are respectively connected to the front wire clamp and the rear wire clamp, the driving component is connected to the stranded tube and is used to drive the stranded tube to drive the front wire clamp and the rear wire clamp to rotate synchronously.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: it further includes a front pushing mechanism for pushing the front pressure clamp and opening the front pressure clamp, and a rear pushing mechanism for pushing the rear pressure clamp and opening the rear pressure clamp.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the front fixing mechanism or the rear fixing mechanism includes a wire pressing head and a wire pressing pad located on one side of the wire pressing head, and the wire pressing head is connected to a wire pressing drive member that drives it away from or closer to the wire pressing head.

[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: both the front fixing mechanism and the rear fixing mechanism are installed on the guide rail, and the positions of the front fixing mechanism and the rear fixing mechanism on the guide rail are adjustable.

[0009] The beneficial effects of this utility model are as follows: After the insulation coating of the rear section of the twist is laser-fused into one piece, multiple wires are firmly combined together. Even if the wire has a large elasticity, it can resist its elastic recovery force, effectively preventing the rear section of the twist from becoming loose during wire feeding and looping. This ensures that the rear section of the twist can pass smoothly through the magnetic ring, avoids looping failure caused by the twist coming loose, and ensures the normal progress of the winding process. On the other hand, since the laser only acts on the rear section of the twist, the firm connection of the rear section of the twist also ensures that the front section of the twist can maintain a tight hinged state, avoiding damage to the front section of the twist and affecting the performance of electronic devices. At the same time, it solves the problem of loose winding caused by the loose front section of the twist, ensuring consistent product quality. Attached Figure Description

[0015] Reference Figure 1 This application proposes an embodiment of a stranded wire mechanism with laser melting, which includes a laser emitter 10 and a front fixing mechanism 20, a front wire clamp 30, a rotating mechanism 40, a rear wire clamp 50, and a rear fixing mechanism 60 arranged sequentially along the copper wire traveling direction. The rotating mechanism 40 is used to drive the front wire clamp 30 and the rear wire clamp 50 to rotate synchronously, and the laser emitter 10 is used to emit a laser to melt the copper wire between the rear wire clamp 50 and the rear fixing mechanism 60.

[0016] After the stranding mechanism receives the wire delivered to it, the front fixing mechanism 20, the front wire clamp 30, the rear wire clamp 50, and the rear fixing mechanism 60 all clamp the wire. Then, the rotating mechanism 40 drives the front wire clamp 30 and the rear wire clamp 50 to rotate and form the front section and the rear section of the twist. The insulating coating of the rear section of the twist is partially or completely fused using a laser device. The laser has the characteristic of high energy density and can accurately act on the insulating coating of the rear section of the twist wire, so that the coating melts and fuses with each other after being heated and solidified, thereby bonding the multiple wires of the rear section of the twist into a whole.

[0017] After the insulation coating of the rear section of the twist is laser-fused into one piece, multiple wires are firmly bonded together. Even if the wire has high elasticity, it can resist its elastic recovery force, effectively preventing the rear section of the twist from becoming loose during the winding and looping process. This ensures that the rear section of the twist can pass smoothly through the magnetic ring, avoiding looping failure caused by the twist coming loose, and ensuring the normal progress of the winding process. On the other hand, since the laser 10 only acts on the rear section of the twist, the firm connection of the rear section of the twist can also ensure that the front section of the twist can maintain a tight hinged state, avoiding damage to the front section of the twist and affecting the performance of electronic devices. At the same time, it solves the problem of loose winding caused by the loose front section of the twist, ensuring consistent winding products and quality.

[0018] Specifically, the rotating mechanism 40 includes a driving component 41 and a stranded tube 42. The two ends of the stranded tube 42 are respectively connected to the front wire clamp 30 and the rear wire clamp 50. The driving component 41 is connected to the stranded tube 42 and is used to drive the stranded tube 42 to drive the front wire clamp 30 and the rear wire clamp 50 to rotate synchronously.

[0019] Referring to the accompanying drawings, the drive assembly 41 is a belt drive assembly. The tension belt is wound around the stranded tube 42, which can drive the stranded tube 42 to drive the front clamping head 30 and the rear clamping head 50 to rotate synchronously.

[0020] Based on the above structure, the stranding mechanism with laser-fused sheath in this embodiment further includes a front pushing mechanism 70 for pushing and opening the front clamping head 30, and a rear pushing mechanism 80 for pushing and opening the rear clamping head 50. The automatic opening of the front clamping head 30 and the rear clamping head 50 is achieved through the rear pushing mechanism 80 and the front pushing mechanism 70, facilitating wire feeding.

[0021] In this embodiment, the front wire clamp 30, the rear wire clamp 50, the rear pushing mechanism 80, and the front pushing mechanism 70 are existing technologies, such as the front wire clamp or rear wire clamp and pushing device described in the patent document with announcement number CN105788851B. The structure of these components will not be described in detail in this embodiment.

[0022] Specifically, the front fixing mechanism 20 or the rear fixing mechanism 60 includes a wire pressing head 90 and a wire pressing pad 100 located on one side of the wire pressing head 90. The wire pressing head 90 is connected to a wire pressing drive member 110 that drives it away from or closer to the wire pressing head 90.

[0023] When wire pressing is required, the wire pressing drive 110 drives the wire pressing head 90 to approach the wire pressing pad 100 to press the wire. After stranding, when the wire is being transported, the wire pressing drive 110 drives the wire pressing head 90 away from the wire pressing pad 100.

[0024] In this embodiment, the pressure wire drive 110 is a cylinder.

[0025] The twisting mechanism includes a machine base with a guide rail 120. The front fixing mechanism 20 and the rear fixing mechanism 60 are both mounted on the guide rail 120, and their positions on the guide rail 120 are adjustable. This allows for adjustment of the distance between the front fixing mechanism 20 and the front clamping head 30, or the distance between the rear fixing mechanism 60 and the rear clamping head 50, thereby making the lengths of the front and rear twists adjustable.

[0026] Referring to the accompanying drawings, the front fixing mechanism 20 and the rear fixing mechanism 60 are slidably mounted on the guide rail 120 and locked on the guide rail 120 by fasteners. When it is necessary to adjust the position of the front fixing mechanism 20 and the rear fixing mechanism 60, the fasteners can be loosened to adjust the position of the front fixing mechanism 20 and the rear fixing mechanism 60.

[0027] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
