Description

Technical Field

[0001] This invention relates to the field of winding equipment, and more particularly to a double-winding equipment. Background Technology

[0002] A coil is a key component of a commonly used electronic device. It is generally made by winding equipment. There are several types of wires used for winding, including round, square, and enameled wire. Enameled wire is a commonly used winding material.

[0003] There are many types of coils, some of which are composed of two sets of coils connected together, i.e., double coils. When winding these coils, there are two main types. The first type is to wind them into two coils and then connect them. The second type is to wind them twice on one winding machine. After the first winding is completed, the coil with the first winding is cut off and then the second winding is performed. It is difficult to control the wire bundle distance between the coils after the two windings. If a more precise control of the wire bundle length between the two coils is required, the position of the coil cut off in the first winding needs to be precisely defined to control its distance from the coil wound in the second winding. This type of control structure is complex, the equipment cost is high, and it will also affect the overall winding efficiency. Summary of the Invention

The positioning device includes a positioning mounting seat set on the frame. The positioning mounting seat is provided with a positioning push cylinder and a micro-adjustment head that run parallel to the winding shaft. The positioning push cylinder is connected to the positioning push block and is limited by the micro-adjustment head. The positioning push block is connected to a positioning insertion and removal cylinder. The positioning insertion and removal cylinder is connected to a positioning insertion block. The positioning insertion block is concave, and the notch is larger than the diameter of the winding shaft. Bearings are installed on the upper and lower parts of the positioning insertion block on the winding shaft. The bearings make tangential contact with the positioning movable disc and push the positioning movable disc to move inward.

[0010] Preferably, the frame has a movable slot, and the lower part of the frame is provided with a winding movable motor and a winding movable lead screw. The winding movable lead screw is sleeved with a winding movable block. The winding movable block passes through the movable slot and is connected to the winding movable seat.

[0011] Preferably, the winding shaft seat is provided with a wire clamping movable cylinder in a direction parallel to the winding shaft near the wire harness entry end. The wire clamping movable cylinder is connected to a wire clamping movable block. The wire clamping movable block is provided with a vertically oriented wire clamping cylinder. The wire clamping cylinder is connected to a movable wire clamping block. The movable wire clamping block is provided with a fixed wire clamping block that cooperates with the movable wire clamping block. The part of the wire clamping movable block between the movable wire clamping block and the fixed wire clamping block is a slot. The height of the slot is matched with the height of the winding shaft.

[0012] Preferably, the wire cutting device includes a wire cutting mounting base disposed on the winding device. The wire cutting mounting base is provided with a wire cutting movable structure that can move laterally and vertically. The wire cutting movable structure is provided with a vertically oriented wire cutting cylinder and the wire cutting mounting base. The wire cutting cylinder is connected to a wire cutting lifting block that passes through the wire cutting mounting base. The wire cutting mounting base is provided with a shearing structure and a wire pressing structure that cooperate with the wire cutting lifting block. The wire cutting movable structure is provided with an upper air duct that cooperates with the wire bundle between the wire pressing structure and the wire guide needle. The winding device is provided with a lower air duct that cooperates with the wire bundle between the wire pressing structure and the wire guide needle.

[0014] Preferably, the wire-cutting lifting block has a wire-cutting groove and a hook-shaped wire harness passage groove. The wire-cutting mounting base is connected to a wire-cutting blade that mates with the wire-cutting groove. The wire-cutting mounting base is connected to a wire-pressing block via a wire-pressing spring. The area where the wire-cutting lifting block and the wire-pressing block mate is a plane.

[0015] The technical effects of this invention are as follows: 1. By using two winding mechanisms and winding bases arranged side by side with two perpendicular winding axes, and in conjunction with the winding mechanism, double winding can be achieved, and the distance between the two coils after winding can be limited, reducing the difficulty of double winding and improving the overall winding efficiency.

[0016] 2. The side conical openings of the movement lifting base facilitate the installation of the core pulling device and the positioning device, and facilitate the movement of the movement relative to the movement base.

[0017] 3. The design of the mechanism connecting block, the core-pulling block, and the connecting groove on the core-pulling block can not only work with the core-pulling block to pull the two mechanisms out of the coil as a whole after winding, but also work with the positioning device to position a single mechanism. Furthermore, the connecting groove can limit the range of movement of the mechanism, thereby controlling the distance of the mechanism from the mechanism base and ensuring the effect of subsequent winding.

[0018] 4. The top core device can position and press the corresponding core during the winding process. The feeding device, together with the core pulling device, can press down and feed the completed double coil, ensuring stable feeding.

[0019] 5. The winding device features a hollow winding shaft, allowing the wire bundle to pass through it. It also allows for the installation of a positioning pin that moves axially relative to the winding shaft. During the rotation and reciprocating winding process of the lead needle, the positioning pin remains in contact with the winding mechanism, ensuring a good winding effect.

[0020] 6. The design of the positioning groove on the winding shaft and the positioning movable disc it is fitted with can convert the axial movement of the positioning top column inside the winding shaft into the movement of the positioning movable disc on the winding shaft, thus facilitating the structural design of the positioning device.

[0021] 7. The positioning device uses a side-concave positioning block as the component that drives the positioning movable plate to move. This avoids interference with the winding shaft and can synchronize the upper and lower parts of the positioning movable plate, ensuring smooth movement of the positioning movable plate and preventing jamming between the positioning movable plate and the winding shaft. Furthermore, the bearing is designed to be tangent to the positioning movable plate, so it will not interfere with the rotation of the positioning movable plate.

[0022] 8. The design of the wire clamping device allows the wire harness to be pulled a certain distance before the core is replaced, thus preventing the wire harness from breaking during the core replacement process.

[0023] 9. The design of the upper and lower air ducts enables the enameled wire to become sticky through hot air, thereby ensuring the stability of the coil shape during the winding process and after winding.

[0024] 10. The design of the wire cutting device, through the design of the wire cutting lifting block and its wire cutting groove, combined with the wire pressing block and wire cutting blade connected by the wire pressing spring, can realize the operation of pressing the wire bundle before cutting it.

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0040] like Figure 1-2 and Figure 10-11As shown, the specific structure of the present invention is as follows: a double-winding device includes a frame 1, a winding device 2 is provided on the frame 1, the winding device 2 winds the wire through a wire needle 20 that moves axially and rotates, and a wire cutting device 4 is provided on the winding device 2 for cutting and clamping the end of the wire bundle. The frame 1 is also provided with a core mechanism 6, the core mechanism 6 includes a core transverse moving device 51 provided on the frame 1 and perpendicular to the axis direction, the core transverse moving device 51 is connected to a core transverse moving seat 52, the core transverse moving seat 52 is provided with a core lifting device 53, the core lifting device 53 is connected to a core lifting seat 54, two core seats 55 are installed side by side on the core lifting seat 54, and a core 69 that can move relative to each other is inserted and installed in both core seats 55, the core 69 is equipped with a core moving structure that drives its movement.

[0041] The specific operation of this invention is as follows: First, the wire harness is passed through the wire needle 20, then pressed by the wire cutting device 4 and the excess part is cut off. Then, the mechanism 6 is driven to the winding position by the mechanism lateral movement device 51 and the mechanism lifting device 53. Then, the mechanism 69 is pushed out of the mechanism seat 55 by the mechanism movement structure. Then, the wire needle 20 is driven to rotate and reciprocate axially by the winding device 2 to wind the coil on the part of the mechanism 69 that exceeds the mechanism seat 55. After the coil winding of this mechanism is completed, the mechanism 6... The transverse movement device 51 and the lifting device 53 of the movement drive another movement to the winding position. Then, the partial ejection and winding operation of the movement 69 is repeated to complete the winding of the second coil. After that, the wire cutting device 4 can loosen the end of the wire harness and move to press and cut the wire harness between the wire needle and the wound double coil. Then, the two movements are pulled out through the movement structure of the movement. The wound coil will fall under the action of gravity. An inclined feeding chute 7 can be set on the frame 1 to send the fallen double coil away.

[0042] like Figure 10-13As shown, the movement lifting seat 54 is a hollow, side-conical structure with openings at the top and bottom. The movable movement structure includes a movement connecting block 64 connecting two movements 69. A horizontally oriented core seat spring 63 is provided between the movement connecting block 64 and the movement lifting seat 54. A core-lifting device 71 is provided on the frame 1, which penetrates from the bottom into the hollow part of the movement lifting seat 54 and pushes out a single movement connecting block 64. A connecting groove 68 is provided on the part of the movement 69 above the movement connecting block, and there is a gap between the connecting groove 68 and the movement connecting block 64. A movement spring is provided between the movement connecting block 64 and the movement 69. Spring 70, a core-pulling device 59 is provided on the mechanical lifting seat 54. The core-pulling device 59 includes a core-pulling cylinder 61 provided on the core-pulling lifting seat 54. The core-pulling cylinder 61 is connected to a core-pulling block 62. The core-pulling block 62 is used to drive the core 69 away from the winding device. The core-lifting device 71 is used to move the core connecting block 64 in the connecting groove 68. The core-lifting device 71 includes a core-lifting cylinder 65 provided on the frame 1. The core-lifting cylinder 65 is connected to a core-lifting seat 66. The core-lifting seat 66 is provided with a core-lifting cylinder 67 that runs horizontally and cooperates with the core connecting block 64.

[0043] The specific activities of the movement are as follows: When the movement is moved to the winding position by the lateral movement and lifting motion, the top core lifting cylinder 65 drives the top core lifting seat 66 to rise, thereby causing the top core cylinder 67 to reach the corresponding height. Then, the top core cylinder 67 presses against the corresponding movement connecting block 64 and drives the movement connecting block 64 to move, thus compressing the core seat spring 63. In this way, the movement seat 55 and the movement 69 are pushed out together. Under the action of the movement spring 70, the movement 69 extends beyond the movement seat 55. Then, the winding part can be used to wind the part of the movement 69 that extends beyond the movement seat 55. After completing this winding of the movement, the top core device is first returned to its original position. Then, through lateral movement and lifting motion, the unwound core 69 is moved to the winding position. Then, the core-lifting operation is repeated. This time, the core-lifting only moves the corresponding core connecting block 64 within the connecting groove 68, which pushes the core 69 and core seat 55 to the winding station. The core 69 is then wound through the winding part to complete the double coil winding. After cutting, the core-pulling cylinder 61 drives the core-pulling block 62 to move away from the winding part, which drives the two cores 69 to move synchronously and enter the core seat 55. This separates the coil on the core 69 from the core, and it falls off under the action of gravity, completing the core-pulling and unloading.

[0044] like Figure 10-12As shown, the movement lifting seat 54 is also provided with a movement seat positioning block 60 that cooperates with the movement seat 55. The movement seat positioning block 60 is provided with positioning screws that cooperate with the two movement seats 55 through screw holes. The side of the movement seat positioning block 60 is provided with positioning screw holes that can cooperate with locking bolts to lock the positioning screws. The movement movable seat 52 is provided with a feeding push cylinder 56. The feeding push cylinder 56 is connected to a vertically oriented feeding lifting cylinder 57. The feeding lifting cylinder 57 is connected to a feeding block 58.

[0045] After the coil is wound, it may stick to the movement base 55, especially when the enameled wire is wound. In order to ensure that the wound double coil can be stably fed, this application uses the feeding push cylinder 56 to drive the feeding lifting cylinder 57 to move, so that the feeding block 58 is above the wound coil. Then, the feeding lifting cylinder 57 drives the feeding block 58 to descend, pressing down the wound coil so that it can be completely separated from the movement base 55, thus completing the feeding.

[0046] The design of the core seat positioning block 60 is mainly to address the potential dimensional errors that may exist between the two core seats 55 during the production and processing process. By using the positioning screw, it ensures that the end faces of the two core seats 55 are in the same plane when they are in the working state.

[0047] like Figure 4-5 As shown, the winding device 2 includes a winding movable seat 11 that can move along its axis. A movable slot is provided on the frame 1, and a winding movable motor 15 and a winding movable lead screw 16 are provided at the lower part of the frame 1. A winding movable block 17 is sleeved on the winding movable lead screw 16. The winding movable block 17 passes through the movable slot and connects to the winding movable seat 11. The winding movable seat 11 cooperates with a winding movable slide rail provided on the frame 1. A winding shaft seat 12 is installed on the winding movable seat 11, and a winding shaft 13 is installed on the winding shaft seat 12. The winding shaft 13 is a hollow shaft. A winding turntable 18 is installed at the winding end, and a wire guide needle 20 is provided on the winding turntable 18. A wire outlet sleeve 19 with shaft cavity communication is provided on the part of the winding shaft 13 near the winding end. The wire bundle enters from the outer end of the winding shaft 13, comes out from the wire outlet sleeve 13, passes through the winding turntable 18, and then exits through the wire guide needle 20. A positioning top post 21 that does not rotate with the winding shaft 13 but can move relative to the axial direction is provided inside the winding shaft 13. The positioning top post 21 extends out of the winding turntable 18 and is pressed and fitted by the mechanism 69. The positioning top post 21 is fitted with a positioning device 5 that drives its axial movement.

[0048] The specific operation of the winding device in this application is as follows: First, the wire harness is inserted into the hollow winding shaft 13, and then out through the wire exit sleeve 19 (to avoid interference with the positioning top post 21). After that, it passes through the winding turntable 18 and the wire needle 20. The end that passes out is pressed by the clamping structure (the wire cutting device in this application), thus completing the wire harness preparation work before winding. Then, the positioning device 5 drives the positioning top post 21 to move inside the winding shaft 13, so that the positioning top post 21 presses against the core that needs to be wound, preventing the wire harness from loosening and detaching from the core during the winding process. Then, the winding motor 14 drives the winding shaft 13 to rotate, and the winding movable motor 15 drives the winding movable seat 11 to move back and forth. In this way, the wire needle 20 can complete the winding operation on the core.

[0049] like Figure 4-6 As shown, the winding shaft 13 has a positioning groove, and a positioning movable disc 22 is sleeved on the part of the winding shaft 13 with the positioning groove. The positioning movable disc 22 can move axially relative to the winding shaft 13. The positioning movable disc 22 is also integrally connected to a positioning push block inserted into the winding shaft 13 from the positioning groove, and the positioning push block pushes the positioning top column 21. The positioning device 5 includes a positioning mounting base 23 set on the frame 1. The positioning mounting base 23 is provided with a positioning push cylinder 2 that runs parallel to the winding shaft 13. 4. The differential adjustment head 28 and the positioning push cylinder 24 are connected to the positioning push block 25, and the positioning push block 25 is limited by the differential adjustment head 28. The positioning push block 25 is connected to the positioning insertion and removal cylinder 26, and the positioning insertion and removal cylinder 26 is connected to the positioning insertion block 27. The positioning insertion block 27 is concave on the side, and the notch is larger than the diameter of the winding shaft 13. The upper and lower parts of the positioning insertion block 27 are equipped with bearings, and the bearings make tangential contact with the positioning movable disk 22 and push the positioning movable disk 22 to move inward.

[0050] The specific operation of the positioning top post 21 is as follows: First, the positioning fork cylinder 26 drives the positioning insert block 27 to move, so that the side notch of the positioning insert block 27 covers the winding shaft. Then, the positioning push cylinder 24 drives the positioning push block 25 and the positioning insert block 27 to move as a whole, and the position is blocked and limited by the micrometer adjustment head 28, so that the bearing installed on the positioning insert block 27 contacts the positioning movable plate 22. With continued pushing, the positioning movable plate 22 moves along the winding shaft 13. In this way, the positioning push block integrated with the positioning movable plate 22 drives the positioning top post 21 to move relative to the winding shaft 13, thereby making the positioning top post 21 press against the winding shaft 13. The positioning top post can be changed by changing the length of the micrometer adjustment head 28 and changing the limited position of the positioning push block 25. The final position of 21 achieves the function of adjusting the overall winding thickness. During the winding process, the positioning movable plate 22 will rotate with the winding shaft 13. Since the bearing and the positioning movable plate 22 are tangentially matched, it will not affect the rotation of the positioning movable plate 22. After the coil winding is completed, the positioning top post 21 needs to return to its original position. This is generally achieved by the reset spring connected to the positioning top post 21. That is, a slot is opened on the positioning push block, and the spring connected to the positioning top post 21 passes through the slot. The other end is installed in the winding shaft (and the installed structure can rotate relative to the winding shaft, but cannot move relative to it). In this way, after the positioning device returns to its original position, the positioning top post 21 returns to its original position under the action of the spring. Alternatively, the spring structure can be omitted, and it can be pushed back by the mechanism or manually.

[0051] like Figure 3 and Figure 9 As shown, a wire clamping device 3 is installed on the winding shaft seat 12. The wire clamping device 3 includes a wire clamping movable cylinder 44 located near the wire harness entry end of the winding shaft seat 12 and parallel to the winding shaft 13. The wire clamping movable cylinder 44 is connected to a wire clamping movable block 45. A vertically oriented wire clamping cylinder 46 is provided on the wire clamping movable block 45. The wire clamping cylinder 44 is connected to a movable wire clamping block 47. A fixed wire clamping block 48 that cooperates with the movable wire clamping block 47 is provided on the movable wire clamping block 45. The part of the wire clamping movable block 45 between the movable wire clamping block 47 and the fixed wire clamping block 48 is a slot. The height of the slot is matched with the height of the winding shaft 13.

[0052] When winding the second coil after completing the first coil winding, the wire harness needs to be moved. During this process, the wire harness is prone to breakage, especially the thin enameled wire. To address this issue, this application designs a wire clamping device 3. First, the wire clamping movable cylinder 44 drives the wire clamping movable block 45 away from the winding shaft seat 12. Then, the wire clamping cylinder 46 drives the movable wire clamping block 47 to cooperate with the fixed wire clamping block 48 to clamp the wire harness. Then, the wire clamping movable cylinder 44 returns to its original position, thus pulling the wire harness out a certain distance, matching the length between the two coils. After that, the wire clamping cylinder 46 returns to its original position, so that the wire harness is in a relaxed state. When changing the winding position, the wire harness is relaxed, thus avoiding breakage.

[0053] like Figure 3 and Figure 7 As shown, the wire cutting device 4 includes a wire cutting mounting base 31 mounted on the winding device 2. The wire cutting mounting base 31 is provided with a wire cutting movable structure that can move horizontally and vertically. The wire cutting movable structure is provided with a vertically oriented wire cutting cylinder 36 and a wire cutting mounting base 37. The wire cutting cylinder 36 is connected to a wire cutting lifting block 38 that passes through the wire cutting mounting base 37. The wire cutting mounting base 37 is provided with a cutting structure and a pressing structure that cooperate with the wire cutting lifting block 38. The wire cutting movable structure is provided with an upper air duct 8 that cooperates with the wire bundle between the pressing structure and the guide needle 20. The winding device 2 is provided with a lower air duct 9 that cooperates with the wire bundle between the pressing structure and the guide needle 20. Both the upper air duct 8 and the lower air duct 9 are connected to a hot air supply structure.

[0054] This application provides an upper air pipe 8 and a lower air pipe 9 on the wire cutting device 4 and the winding device 2, respectively. The upper air pipe is set on the wire cutting movable structure so that it moves together with the wire cutting structure and the wire pressing structure. This ensures that the upper air pipe 8 and the lower air pipe 9 can heat the wire bundle between the wire pressing structure and the wire needle 20 with hot air, so that the enameled wire becomes sticky after heating. In this way, during the subsequent coil winding process, the wound wire bundles will stick together with each other, ensuring that the wound wire bundles are stable and will not loosen.

[0055] like Figure 7 As shown, the wire-cutting movable structure includes a wire-cutting transverse cylinder 32 on a wire-cutting mounting base 31, a wire-cutting movable base 33 connected to the wire-cutting movable base 33, a wire-cutting lifting cylinder 34 on the wire-cutting movable base 33, a wire-cutting lifting base 35 connected to the wire-cutting lifting base 34, an upper air pipe 8 on the wire-cutting transverse movable base 33, and a wire-cutting cylinder 36 and a wire-cutting mounting base 37 on the wire-cutting lifting base 35.

[0056] The wire-cutting mechanism uses a wire-cutting horizontal cylinder 32 and a wire-cutting lifting cylinder 34 to move the wire-cutting lifting seat 35 laterally and lift it up. This allows the next coil to be wound automatically and the end of the previous double coil to be cut off after the winding is completed, thus achieving automated continuous double winding operation.

[0057] like Figure 8 As shown, the wire cutting lifting block 38 has a wire cutting groove 39 and a hook-shaped wire harness passage groove. The wire cutting mounting base 37 is connected to a wire cutting blade 40 that cooperates with the wire cutting groove 39. The wire cutting mounting base 37 is connected to a wire pressing block 42 by a wire pressing spring 41. The area where the wire cutting lifting block 38 and the wire pressing block 42 cooperate is a plane.

[0058] Between wire cutting and wire pressing, the wire cutting lifting block 38 and the wire cutting mounting base 37 are first moved laterally and raised and lowered by the wire cutting horizontal cylinder 32 and the wire cutting lifting cylinder 34, so that the wire harness passes through the part between the pressing block and the wire cutting lifting block 38 and enters the through groove. Then, the wire cutting cylinder 36 drives the wire cutting lifting block 38 to rise, so that the pressing block 42 presses the wire harness tightly on the wire cutting lifting block 38. As the wire cutting lifting block 38 continues to rise, it will compress the pressing spring 41, and at the same time, the wire cutting blade 40 will work with the wire cutting groove 39 to cut the wire harness. The wire pressing operation is completed before the wire cutting, which can ensure the wire cutting effect.
