Description
Technical Field
[0001] The utility model relates to the field of copper wire wrapping tape, in particular to a wrapping tape mechanism suitable for thin wires. Background Art
[0002] In today's market, most windings are made of wire turns wound on a bobbin, and the most common wire turns are copper wire.
[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, which is when the copper wire is wound around one frame and then wound around another frame. Figure 1 As shown in the figure, this process is called crossing the 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, there is no structural optimization 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 wires, the copper wires are dragged on the frame. At this time, the tape C-2 originally wrapped around the copper wires is easily cut by the sharp corners 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 winding tape C-2 for multiple copper wires twice. 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 extremely susceptible to environmental influences (such as wind and machine vibrations) and shaking, especially flat copper wires. Flat copper wires are very likely to overlap with each other (the probability of overlapping is higher for flat wires C-1 than for round wires). 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 impact on the yield rate of fine wire winding. In other words, due to the lack of corresponding design, the current tape wrapping mechanism has an extremely low yield rate in producing fine wire winding. Utility Model Content
[0009] In order to solve the above problems, the utility model provides a tape wrapping mechanism suitable for thin wires, aiming to solve the problem that copper wires are easily overlapped, resulting in extremely low yield rate of thin wire winding production.
[0010] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0011] A tape wrapping mechanism for thin wires, characterized in that the tape is wrapped around a copper wire close to a 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 wiring harness matrix. The wiring harness matrix is provided with at least two groups, which are opposite to each other and have reserved gaps adapted to single copper wires. The tape used for secondary wrapping on the side of the copper wire is constrained by the wiring harness matrix and is folded in half to adhere to the multiple copper wires. The head and tail ends of the tape are successively wrapped around the multiple copper wires as the rotating component rotates.
[0013] Beneficial effects of the utility model:
[0014] 1. The utility model utilizes the method of winding the copper wire with tape inside the rotating component, which has the characteristic of taking up less longitudinal space. The length direction of the copper wire is longitudinal, which coincides with the rotation axis of the rotating component. With the use of the 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 wound around multiple strands of copper wires. It is not difficult to see that this structure has the characteristic of small amplitude of movement, and the tape can be wound around the copper wire in a small space. Therefore, the utility model can be compatible between the winding mechanism and the sleeve 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 wiring 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 wiring harness matrix provides sufficient contact surface to assist the connection between the tape and the copper wire, preventing the tape from naturally falling due to insufficient support at one end, avoiding the spiral wrapping form, and eliminating the situation that affects 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 tape assembly also includes a rotating motor, a belt, and a gear set. The rotating motor is engaged with the gear set through the belt, and the gear set drives the driven gear to rotate.
[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, the upper end of the driven gear is provided with a pair of connecting seats with notches facing each other, 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 finger is 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. 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. The pressure plate is arranged behind the bottom plate and is in a relative state to the glue pressing sheet. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] This specific embodiment is a winding coil winding machine.
[0039] In order to fully illustrate the technical principles of the present invention, the thin wire in the specific implementation method 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 1 mm, the thickness is 0.8 mm, and the length is not limited. Of course, this is just an example and not a further limitation of the utility model.
[0040] The tape wrapping mechanism 1 and the winding mechanism are both located in the middle part of the whole machine, and the sleeve feeding mechanism (the sleeve feeding mechanism belongs to the upper part of the whole machine) is located above the tape wrapping mechanism 1. The winding mechanism has the function 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 provided in the middle part of the whole machine includes:
[0042] The bottom plate 100, and the pulling tape assembly A and the 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 Figures 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 adapted to the width of the single flat wire C-1 is reserved between the brushes B-12. The multiple 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 folded in half. Under the action of the tip, the tape C-2 is bonded to the 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 flat wire C-1 is 1 mm wide and 0.8 mm thick. The contact area between the tape C-2 and the flat wire C-1 is very small, and the adhesive force is relatively weak, so it is easy for the tape C-2 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 carrying the tape C-2 enters the driven gear B-10, the brush B-12 will deform. 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. This allows the protective effect of the tape C-2 to be concentrated on a certain area. When crossing the wires, 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. In this case, a longer brush B-12 can be used. The advantage is that the tip of the brush B-12 will be softer, which can more fully distribute the pressure on the tape C-2.
[0049] As can be seen from the figure, this way of setting the brush B-12 inside the driven gear B-10 occupies less longitudinal space. For the winding machine, only with 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 Figure 10 As shown, a pair of connecting seats B-14 with recesses B-16 are provided at the upper end of the driven gear B-10, which are opposite to each other. The fixing frame B-15 is fixed in the recess B-16, and the brush B-12 is connected to the side of the fixing frame B-15.
[0052] like Figure 11 As shown, the rotating 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 set on the base plate 100. The rotating motor B1 is fixed below the base plate 100. The rotating motor B1 is engaged with the gear set B3 through the first belt B2, and drives the driven gear B-10 to rotate through the gear set B3.
[0053] The method of using the gear set B3 in conjunction with the driven gear B-10 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 to pull the 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 outside to inside (such as Figure 4 The Y direction in the figure), the pulling path of the tape C-2 is the moving path that passes through 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 pulling 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 outside of the base plate 100 and close to the area of the driven gear B-10. The transport component is set on the right part of the base plate 100 in a posture where the transport end arrives at the above-mentioned area, and the transport component and the moving path of the flat wire C-1 moving to the driven gear B-10 intersect. In this regard, after the pneumatic finger A-3 is assembled to the movable end of the transport 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 to the inside of the driven gear B-10.
[0057] like Figure 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 loop 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 existing technology, part of the tape loop 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 Figure 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 set in the tape cutting area. The second part includes a cutter A-500, a cutter cylinder A-501, a cutter slide A-502, a glue pressing sheet A-503, a glue pressing slide A-504, a glue pressing cylinder A-505, a guide seat A-506, and a pressure plate A-507. The cutter cylinder A-501 is connected to the cutter A-500 through the cutter slide A-502. Similarly, the glue pressing cylinder A-505 is connected to the cutter A-500 through the cutter slide A-502. The cylinder A-505 is connected to the glue pressing sheet A-503 through the glue pressing slide 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 pressure plate A-507 is L-shaped. The pressure 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 on the pressure 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. The guide seat A-506 has guide openings 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 openings can be constrained by the guide openings to prevent the cutter slide A-502 and the glue pressing slide A-504 from deviating in their movement directions.
[0062] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not 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 technicians in this field should fall within the scope of protection determined by the claims of the present invention.
