Description

Technical Field

[0001] The invention relates to the field of copper wire wrapping tape, in particular to an adhesive tape wrapping mechanism suitable for thin wires. Background Art

[0002] In today's market, most windings are made of wire turns wound on a frame, and the most common wire turns are copper wires.

[0003] For the above-mentioned type of winding, most products have a single or multiple copper wires wound around a single frame, while a small number of products have different frames wound continuously.

[0004] For this type of copper wire that is continuously wound around different frames, the process involves a cross-line process, in which the copper wire is wound around one frame and then wound around another frame. Figure 1 As shown, this process is called cross-wire (the lines in the figure are copper wires, and the arrows are the winding directions of the copper wires on a single skeleton).

[0005] At present, no structural optimization has been made on the skeleton to adapt to the cross-line means. The structure on the frame is similar to the corners. From the figure, we can know that the copper wire and the frame have intersections (such as Figure 1 When crossing the wire, the copper wire is dragged on the frame. At this time, the tape C-2 originally wrapped on the copper wire is easily cut by the edges of the frame.

[0006] The solution to the above problem is to wrap a layer of tape C-2 around the area corresponding to the cross-line on the copper wire to increase the thickness, which can effectively prevent the copper wire from being exposed.

[0007] At present, there is a mechanism for secondary winding tape C-2 for multiple copper wires. This mechanism is located in the upper part of the whole machine, and the winding mechanism is located in the middle part of the whole machine. When facing copper wires with relatively small diameters, the two mechanisms are far apart in position, making such copper wires very susceptible to environmental influences (such as wind and machine vibration, etc.) and shaking, especially flat copper wires. It is very easy for flat copper wires to overlap each other (the probability of overlapping of flat wire C-1 is higher than that of round wire). This combination state is bulging on the skeleton (such as Figure 3 As shown, when arranging the wires in the future, this will affect the subsequent winding of the next layer.

[0008] It is not difficult to see that this secondary tape wrapping C-2 mechanism has a great influence on the yield rate of fine wire winding. In other words, the current tape wrapping mechanism has an extremely low yield rate for producing fine wire windings due to the lack of corresponding design. Summary of the invention

[0009] In order to solve the above problems, the present invention provides a tape wrapping mechanism suitable for thin wires, aiming to solve the problem that copper wires are easily overlapped, resulting in extremely low production yield of thin wire windings.

[0010] To achieve the above object, the technical solution adopted by the present invention is:

[0011] A tape wrapping mechanism suitable for thin wires, characterized in that the tape is wound around the copper wire close to the winding mechanism, and the thin wire tape wrapping mechanism winds new tape on the copper wire from the following structure:

[0012] A rotating component that rotates along its own rotation axis is arranged in the thin wire wrapping tape mechanism. The rotating component is a local enclosing structure with an internal harness body matrix. The harness body matrix is ​​provided with at least two groups, the groups are opposite to each other, and gaps adapted to single copper wires are reserved, so that the tape used for secondary wrapping on the side of the copper wire is constrained by the harness body matrix and bonded to the multiple copper wires in a folded form, and the head and tail ends of the tape are successively wound around the multiple copper wires following the rotation of the rotating component.

[0013] Beneficial effects of the present invention:

[0014] 1. The present invention utilizes a method of winding tape around the copper wire inside a rotating component, which has the characteristic of occupying less longitudinal space. The length direction of the copper wire is longitudinal, coinciding with the rotation axis of the rotating component. With the use of a wiring harness matrix, the tape can be simultaneously adhered to multiple strands of stationary copper wires. Combined with the rotation of the rotating component, the entire tape can be simultaneously wrapped around multiple strands of copper wires. It is not difficult to see that this structure has the characteristic of a small amplitude of motion, and the tape can be wound around the copper wire in a small space. Therefore, the present invention can be compatible between the winding mechanism and the casing delivery mechanism. In other words, it can be close to the winding mechanism, and the clamping effect of the winding mechanism on the copper wire can be utilized, thereby avoiding the overlap between the copper wires.

[0015] 2. There is a gap between the harness matrix for a single copper wire. First of all, this gap can maintain the existence of the tape. The tape is folded in half and pushed into the gap by the copper wire. At this time, the harness matrix provides sufficient contact surface to assist the connection between the tape and the copper wire, preventing the tape from falling naturally due to insufficient support at one end, avoiding spiral wrapping, and eliminating situations that affect the protection performance.

[0016] Furthermore, the above-mentioned partial enclosing structure is that an opening is formed on the side of the rotating component.

[0017] Furthermore, the rotating component is a driven gear, and the thin wire wrapping tape assembly also includes a rotating motor, a belt, and a gear set. The rotating motor is meshed with the gear set through the belt, and the driven gear is driven to rotate by the gear set.

[0018] Furthermore, the wire harness matrix is ​​provided in a group and is opposite to each other, and the wire harness matrix is ​​a brush.

[0019] Furthermore, the brush extends to the top and bottom of the driven gear. Under this design, the contact with the tape is more complete.

[0020] Furthermore, it also includes a fixing frame, a pair of connecting seats with notches facing each other are arranged on the upper end of the driven gear, the fixing frame is fixed in the notches, and the brush is connected to the side of the fixing frame.

[0021] Furthermore, it also includes a base plate and a tape pulling assembly arranged on the base plate. The tape is guided by the tape pulling assembly and intersects with the moving path of the copper wire. The tape pulling assembly includes a tape ring, multiple guide wheels, pneumatic fingers, and a transportation assembly. The tape ring and guide wheels are arranged on the base plate, and finally the tape is guided to the area outside the base plate and close to the driven gear. The transportation assembly is arranged on the base plate in a posture where the transportation end point arrives at the above-mentioned area, and the pneumatic fingers are assembled to the movable end of the transportation assembly.

[0022] Furthermore, the transport assembly includes a servo motor, a driving wheel, a driven wheel, and a belt. The driving wheel and the driven wheel are rotatably arranged on the base plate, the belt is sleeved on the driving wheel and the driven wheel, the pneumatic finger is connected to the belt, and the servo motor is located below the base plate and is drive-connected to the driving wheel.

[0023] Furthermore, the bottom plate has a tape cutting area adjacent to the driven gear, and the tape pulling assembly also includes a cutter, a cutter cylinder, a cutter slide, a glue pressing sheet, a glue pressing slide, a glue pressing cylinder, and a pressure plate arranged in the tape cutting area. The cutter cylinder is connected to the cutter through the cutter slide, and the glue pressing cylinder is connected to the glue pressing sheet through the glue pressing slide. The moving paths of the glue pressing sheet and the cutter intersect with the moving path of the tape, and the pressure plate is arranged behind the bottom plate and is in a relative state to the glue pressing sheet.

[0038] This specific embodiment is a winding winding machine.

[0039] In order to fully explain the technical principle of the present invention, the thin wire in the specific implementation mode will use the flat wire C-1 as the raw material to further illustrate the present invention. The width of the flat wire C-1 is 1mm, the thickness is 0.8mm, and the length is not limited. Of course, this is just an example and not a further limitation of the invention.

[0040] The tape wrapping mechanism 1 and the winding mechanism are both located in the middle part of the whole machine, and the sleeve delivery mechanism (the sleeve delivery mechanism belongs to the upper part of the whole machine) is located above the tape wrapping mechanism 1. The winding mechanism has the action of clamping the thin wire. This action makes the area of ​​the flat wire C-1 close to the winding mechanism in a fairly stable state and will not shake due to external influences.

[0041] like Figure 4 As shown, the tape wrapping mechanism 1 arranged in the middle part of the whole machine includes:

[0042] A bottom plate 100, and a pulling tape assembly A and a rotating wrapping tape assembly B arranged on the bottom plate 100.

[0043] The tape pulling component A is used to provide the tape C-2. After the flat wire C-1 contacts the sticky surface of the tape C-2, it enters the rotating tape wrapping component B. The structure that wraps the tape in the rotating tape wrapping component B is the driven gear B-10.

[0044] The driven gear B-10 includes the following structure:

[0045] like Figure 2 , 5 As shown in , 6, 7, 8, and 9, an opening B-11 is provided on the side of the driven gear B-10, and the opening B-11 is a channel for the flat wire C-1 to enter the internal space. A pair of brushes B-12 facing each other are provided in the internal space of the driven gear B-10, and a gap B-13 matching the width of the single-strand flat wire C-1 is reserved between the brushes B-12. The multiple-strand flat wires C-1 enter the channel in sequence (arrow Y is the entry direction of the flat wire C-1), and the flat wire C-1 that first enters the channel is pushed The tape C-2 enters the gap B-13. When the flat wire C-1 moves in the gap B-13, the tape C-2 is constrained by the tip of the flat wire C-1 and forms a folded state. Under the action of the tip, the tape C-2 is bonded to other flat wires C-1. When the driven gear B-10 rotates, the brush B-12 rotates around the flat wire C-1, wrapping the tape C-2 around the flat wire C-1. Finally, there is a new, even and smooth layer of tape C-2 on the area where the flat wire C-1 crosses the line.

[0046] As mentioned above, the width of the flat wire C-1 is 1mm and the thickness is 0.8mm. The contact area between the tape C-2 and the flat wire C-1 is very small, and the adhesive effect is relatively weak, so it is easy to fall off the flat wire C-1. There is a gap B-13 between the brushes B-12 for a single flat wire C-1 to pass through. When the flat wire C-1 enters the driven gear B-10 with the tape C-2, the brush B-12 will be deformed. At this time, the brush B-12 will play an auxiliary and supporting role. The tip of the brush B-12 provides a thrust to the tape C-2 on the flat wire C-1, which effectively solves the problem of the tape C-2 falling off the flat wire C-1.

[0047] In addition, the gap B-13 between the brushes B-12 for the single flat wire C-1 to pass through has another effect, which is to ensure that the winding of the tape C-2 is not spiral, so that the protective effect of the tape C-2 can be concentrated on a certain area. When crossing the line, it will not lose its due protective ability due to excessive dispersion of the wrapping.

[0048] Furthermore, the internal space extends toward the rim a of the driven gear B-10. At this time, a longer brush B-12 can be used. The advantage is that the tip of the brush B-12 will be softer and can more fully distribute the pressure on the tape C-2.

[0049] As can be seen from the figure, the way in which the brush B-12 is set inside the driven gear B-10 occupies less longitudinal space. For the winding machine, only in a smaller longitudinal space can the position of the tape wrapping mechanism be adjusted to the periphery of the winding mechanism.

[0050] Furthermore, the brushes B-12 are distributed above and below the driven gear B-10. Under this design, a larger number of brushes B-12 can be provided, which makes the contact with the tape C-2 more complete.

[0051] like Fig.10 As shown, a pair of connecting seats B-14 with notches B-16 are provided at the upper end of the driven gear B-10, and the fixing frame B-15 is fixed in the notches B-16, and the brush B-12 is connected to the side of the fixing frame B-15.

[0052] like Fig.11 As shown, the rotating wrapping tape assembly B includes a rotating motor B1, a first belt B2, and a gear set B3. The driven gear B-10 and the gear set B3 are both rotatably arranged on the base plate 100. The rotating motor B1 is fixed under the base plate 100. The rotating motor B1 is meshed with the gear set B3 through the first belt B2, and the driven gear B-10 is driven to rotate through the gear set B3.

[0053] The method of using the gear set B3 and the driven gear B-10 to cooperate has the advantage of high precision and guarantees the number of winding turns. In addition, this specific implementation method has a better space occupancy advantage.

[0054] The tape pulling assembly A includes two parts. The first part is the pulling tape C-2 to ensure that the material length is sufficient. The other function is to make the pulling path of the tape C-2 intersect with the path of the flat wire C-1 entering the driven gear B-10. For example, the moving path of the flat wire C-1 is from the outside to the inside (such as Figure 4 The traction path of the tape C-2 passes through the moving path of the flat wire C-1 and intersects with the flat wire C-1 (arrow X is the length direction of the flat wire C-1, and arrow Z is the traction direction of the tape C-2).

[0055] The first part includes a tape ring A-1, a plurality of guide wheels A-2, a pneumatic finger A-3, and a transport component;

[0056] On one side of the left part of the base plate 100, there is a support plate 101 that supports and is connected to the above-mentioned tape ring A-1. The guide wheel A-2 is distributed on the support plate 101 and the base plate 100, and finally guides the tape C-2 to the area outside the base plate 100 and close to the driven gear B-10. The transportation component is set on the right part of the base plate 100 in a posture that the transportation end point arrives at the above-mentioned area, and the transportation component and the moving path of the flat wire C-1 moving into the driven gear B-10 have an intersection. In this regard, after the pneumatic finger A-3 is assembled to the movable end of the transportation component, it approaches the guide wheel A-2, clamps the tape C-2 on the guide wheel A-2, and drags the tape C-2, so that the tape C-2 is blocked on the moving path of the flat wire C-1 moving into the driven gear B-10.

[0057] like Fig.12 As shown, the transport assembly includes a servo motor A400, a driving wheel A402, a driven wheel A403, and a second belt A401. The driving wheel A402 and the driven wheel A403 are rotatably set on the base plate 100. The second belt A401 is sleeved on the driving wheel A402 and the driven wheel A403. The pneumatic finger A-3 is connected to the second belt A401. The servo motor A400 is located below the base plate 100 and is driven and connected to the driving wheel A402. The advantage of this design is that the overall height of the transport assembly is nearly flush, which prevents interference with the sleeve delivery mechanism above.

[0058] It is not difficult to see that the tape ring A-1 is fixed. The structure of the first part is to further optimize the longitudinal optimization space, and there will be no large movement range of any component. In the prior art, part of the tape ring A-1 rotates around the flat wire C-1, which will cause the stability of the equipment itself to decrease. In addition, it will also cause the actual space occupied by the tape pulling component A to be larger.

[0059] Therefore, in this embodiment, the winding machine of the present invention can simultaneously perform two functions: wrapping the flat wire C-1 with the adhesive tape C-2 and putting a sleeve on the flat wire C-1.

[0060] like Fig.13 , 14As shown, the bottom plate 100 has a tape cutting area adjacent to the driven gear B-10, and the second part of the tape pulling assembly A is arranged in the tape cutting area. The second part includes a cutter A-500, a cutter cylinder A-501, a cutter slide bar A-502, a glue pressing sheet A-503, a glue pressing slide bar A-504, a glue pressing cylinder A-505, a guide seat A-506, and a pressing plate A-507. The cutter cylinder A-501 is connected to the cutter A-500 through the cutter slide bar A-502. Similarly, the glue pressing cylinder A-505 Cylinder A-505 is connected to the glue pressing sheet A-503 through the glue pressing slide bar A-504. The moving paths of the glue pressing sheet A-503 and the cutter A-500 intersect with the moving path of the tape C-2. The pressing plate A-507 is L-shaped. The pressing plate A-507 is arranged behind the base plate 100 and is in a relative state to the glue pressing sheet A-503. The glue pressing sheet A-503 presses the tape C-2 onto the pressing plate A-507 (the tape C-2 is clamped by the pneumatic finger A-3), and the cutter A-500 cuts off the tape C-2.

[0061] The guide seat A-506 is fixed on the base plate 100, and has a guide opening corresponding to the cutter slide A-502 and the glue pressing slide A-504. The cutter slide A-502 and the glue pressing slide A-504 passing through the guide opening can be constrained by the guide opening to prevent the cutter slide A-502 and the glue pressing slide A-504 from deviating in their movement directions.

[0062] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
