Abstract

This utility model discloses a double-wire parallel winding and single-wire independent coating mechanism, relating to the field of wire core processing. It includes a base plate on which two wire feeding machines are fixedly installed, each driving and connecting a wire core. Two tape feeding machines and two tape coating machines are also fixedly installed on the base plate, winding tape onto the wire cores of the two feeding machines. A wire pressing machine is fixedly installed on the base plate, and the wire cores from both feeding machines, after being wrapped with tape, are fed together into the wire pressing machine for pressing and output.

Description

Technical Field

[0001] This utility model relates to the field of wire core processing, and in particular to a double-wire parallel winding single-wire independent coating mechanism. Background Technology

[0002] In today's market, most windings are made by winding wire turns on a bobbin, with copper wire being the most common type of wire. Most products of this type of winding have one or more copper wires wound around a single bobbin, while a smaller number of products have them continuously wound around different bobbins.

[0003] The prior art (announcement number: CN119092292A, announcement date: 2024.12.06) discloses a tape wrapping mechanism suitable for fine wires, which can be compatible between a winding mechanism and a sleeve feeding mechanism. In other words, it can be close to the winding mechanism, and thus can utilize the clamping effect of the winding mechanism on the copper wire, thereby avoiding the overlapping of copper wires.

[0004] However, the insulation effect of the outer surface of the existing copper wires is generally poor before they are wound on the wire frame. When the winding is in the case of high current and voltage, the copper wires are prone to overlapping, which causes the winding to fail to play its corresponding role. Therefore, it is necessary to apply rubber insulation during the copper wire transportation process. Utility Model Content

[0033] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0034] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0035] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] like Figure 1-8 As shown, the present invention provides a double-wire parallel winding single-wire independent coating mechanism, including a base plate 1, on which two wire feeders 2 are fixedly installed, and each of the two wire feeders 2 drives and connects a wire core 3.

[0039] Two tape feeding machines 4 and two tape wrapping machines 5 are fixedly installed on the base plate 1. The tape feeding machines 4 and tape wrapping machines 5 wrap tape around the wire cores 3 of the two wire feeding machines 2 respectively.

[0040] A wire pressing machine 6 is fixedly installed on the base plate 1. The wire cores 3 of the two wire feeders 2 are fed into the wire pressing machine 6 together after being wrapped with tape for wire pressing output.

[0041] The principle is as follows: While the wire conveyor 4 and the tape wrapping machine 5 are conveying the wire core 3, tape is wrapped around the surface of the wire core 3 to achieve full insulation of the wire core 3. At the same time, after the two wire cores 3 are wrapped with tape, they can be pressed into a single wire by the wire pressing machine 6. Since the two sets of wire cores 3 are insulated from each other, the two sets of wire cores 3 can not interfere with each other, which facilitates subsequent winding on the wire frame and thus improves the production quality of the wire set.

[0042] Furthermore: The tape conveyor 4 includes a right-angle frame 41, a lifting platform 42, a lifting plate 43, a tape roller 44, an upper clamp 45, a tape cutter 46, and a lower clamp 47. The right-angle frame 41 is fixedly installed on the base plate 1. The lifting platform 42 is fixedly installed on the upper end of the right-angle frame 41. The lifting plate 43 is vertically arranged. The lifting platform 42 drives the lifting plate 43 to move up and down. The tape roller 44 is rotatably mounted on the lifting plate 43. The upper clamp 45 and the tape cutter 46 are both fixedly installed on the lifting plate 43. The lower clamp 47 is fixedly installed on the base plate 1. A roll of tape 7 is installed on the tape roller 44. After the tape roll 7 is pulled out, it passes through the upper clamp 45 and the tape cutter 46. The lower clamp 47 is located on the tape cutter. Below the machine 46; during operation, the tape roll 7 is pulled out and passes through the upper clamp 45 and the tape cutter 46. The lifting platform 42 drives the entire lifting plate 43 to descend, allowing the pulled-out tape roll 7 to descend to the position of the lower clamp 47. The lower clamp 47 clamps the pulled-out tape roll 7. At this time, the lifting platform 43 is raised by the lifting platform 42, thereby achieving the technical effect of automatically pulling out the tape roll 7. When both the upper clamp 45 and the lower clamp 47 clamp the tape roll 7, the tape cutter 46 can be used to cut the pulled-out tape roll 7. Since the lower clamp 47 clamps the tape roll 7 together with the wire core 3, the cut tape roll 7 can be attached to the wire core 3, which is convenient for subsequent tape wrapping operations.

[0043] Furthermore, the conveyor belt 4 also includes several guide rollers 48, which are rotatably mounted on the lifting plate 43. After the conveyor belt roll 7 is pulled out, it passes through several guide rollers 48 and is then conveyed to the upper clamp 45 and the conveyor belt cutter 46; this ensures stable conveying of the conveyor belt roll 7 after it is pulled out.

[0044] Furthermore: a transverse guide rail 8 is fixedly installed on the lifting plate 43, and a transverse slider 9 is slidably installed on the transverse guide rail 8. One of the transmission rollers 48 is rotatably installed on the transverse slider 9. A reset spring 10 is installed between the transverse slider 9 and the lifting plate 43. A limit cylinder 11 is fixedly installed on the lifting plate 43. A limit ring 12 is fixedly installed at the telescopic rod of the limit cylinder 11. A limit block 13 is formed on the upper side of the transverse slider 9. The limit block 13 is located on the side of the limit ring 12. The reset spring 10 can be used to tighten the pulled-out tape roll 7 to ensure that the tape roll 7 will not wrinkle, thus improving the neatness of each section of tape roll 7 when cut. The setting of the limit cylinder 11, the limit ring 12, and the limit block 13 can realize the fine adjustment of the sliding distance of the transverse slider 9, which is convenient for practical use and can be applied to tape rolls 7 of different specifications.

[0045] Furthermore: A vertical guide rail 14 is fixedly installed on the side wall of the right-angle frame 41, and at least two vertical sliders 15 are installed on the vertical guide rail 14 in an interactive manner. The vertical sliders 15 are fixedly installed on the lifting plate 43; this can ensure the stable lifting and lowering movement of the lifting plate 43 on the right-angle frame 41.

[0046] Furthermore: The upper clamping device 45 includes an upper clamping cylinder 451 and a pressure bar 452. Both the upper clamping cylinder 451 and the pressure bar 452 are fixedly installed on the lifting plate 43. After the tape roll is pulled out, it passes through the gap between the upper clamping cylinder 451 and the pressure bar 452. The pulled-out tape roll 7 can be clamped by the upper clamping cylinder 451 pressing the pressure bar 452, which facilitates the subsequent cutting action.

[0047] Furthermore: The tape cutting machine 46 includes a telescopic cylinder 461 and a serrated blade 462. The telescopic cylinder 461 drives the serrated blade 462 to cut the pulled-out tape roll. The telescopic cylinder 461 drives the serrated blade 462 to cut the tape roll 7. Since the upper clamp 45 and the lower clamp 47 will clamp the tape roll 7 at the same time during the cutting, the technical effect of quickly cutting the tape roll 7 can be achieved.

[0048] Furthermore: The lower clamping device 47 includes a lower clamping cylinder 471, a moving block 472, and a fixed block 473. The lower clamping cylinder 471 and the fixed block 473 are both fixedly installed on the base plate 1. The lower clamping cylinder 471 drives the moving block 472 to move closer to or away from the fixed block 473. The wire core 3 is set through the gap between the moving block 472 and the fixed block 473. The side of the fixed block 473 closest to the moving block 472 has a wire groove 16. This allows the lower clamping device 47 to clamp the tape roll 7 together with the wire core 3, ensuring that the cut tape roll 7 can stick to the wire core 3, and then the tape together with the wire core 3 is transported to the tape wrapping machine 5 for the tape wrapping action.

[0049] Furthermore: The tape wrapping machine 5 includes a motor mounting plate 51, a stepper motor 52, a hollow shaft 53, and a brush assembly 54. The motor mounting plate 51 is vertically arranged and fixedly mounted on the base plate 1. The stepper motor 52 is fixedly mounted on the motor mounting plate 51. The hollow shaft 53 is rotatably mounted on the motor mounting plate 51, and the stepper motor 52 drives the hollow shaft 53 to rotate. The wire core 3 passes through the hollow shaft 53. The brush assembly 54 is rotatably mounted on the right end of the hollow shaft 53. A tape brush 17 is fixedly installed on the right end. The tape brush 17 presses on the wire core 3 and rotates. The wire core 3 can be conveyed inside the hollow shaft 53. The stepper motor 52 drives the hollow shaft 53 to rotate, thereby driving the brush assembly 54 to press on the wire core 3. Since the wire core 3 is conveyed to the inside of the brush assembly 54 together with the tape roll 7, the rotating brush assembly 54 can stably stick and wrap the tape roll 7 on the wire core 3, thereby achieving the technical effect of automatic tape wrapping.

[0050] Furthermore, the tape wrapping machine 5 also includes a clearance cylinder 55, which is fixedly mounted on the base plate 1. The left end of the brush assembly 54 is rotatably fitted with a rolling bearing 18, and the telescopic rod of the clearance cylinder 55 abuts against the rolling bearing 18. During the conveying process, the clearance cylinder 55 can be used to push against the rolling bearing 18 to drive the brush assembly 54 to open, thereby ensuring that the tape on the wire core 3 will not fall off. When the stepper motor 52 is turned on, the tape brush 17 can also be used to press on the wire core 3 to ensure the stability of the tape wrapping.

[0051] Furthermore: A limiting disc 19 is fixedly installed on the left end of the hollow shaft 53. A sensing notch 20 is formed on the limiting disc 19. A slotted photoelectric sensor 21 is fixedly installed on the motor fixing plate 51. The outer edge of the limiting disc 19 is fitted into the slotted photoelectric sensor 21 with a clearance fit. This allows it to automatically sense the rotational position of the hollow shaft 53 and stop after one revolution. At this time, the telescopic rod of the avoidance cylinder 55 will align with the rolling bearing 18, which can effectively prevent the tape roll 7 from falling off during the conveying process of the core 3. After the conveying is in place, the avoidance cylinder 55 releases the rolling bearing 18 and uses the stepper motor 52 to drive the hollow shaft 53 to rotate a full revolution, thereby pressing the tape brush 17 onto the core 3 to achieve stable wrapping of the tape roll 7 on the core 3.

[0052] Furthermore, the wire pressing machine 6 includes several rotating wheels 61, several pressing wheels 62, and several pressing cylinders 63. After the wire cores 3 are output from the two wire feeders 2, they are fed between the rotating wheels 61 and the pressing wheels 62 for pressing. The rotating wheels 61 are rotatably mounted on the base plate 1, and the pressing cylinders 63 are fixedly mounted on the base plate 1. The pressing cylinders 63 drive the pressing wheels 62 to be positioned close to the rotating wheels 61 one by one. The two sets of wire cores 3 wrapped with tape rolls 7 can be fed together to the wire pressing machine 6 for pressing, thereby combining the two sets of wire cores 3 into one, which facilitates the subsequent winding action on the wire frame.

[0053] Furthermore: the wire core 3 is made of copper wire, and the tape roll 7 is made of insulating film.

[0054] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
