Description

Technical Field

[0001] The invention relates to the technical field of coil winding, in particular to a coil winding and forming device for an automobile electromagnetic switch. Background Art

[0002] The automotive electromagnetic switch coil is essentially a ring structure made of wire made of a specific material. It has unique electromagnetic properties. When the current is turned on or off or changes inside it, a corresponding magnetic field is generated. The interaction force of the magnetic field is used to accurately control the movement of related mechanical components, ensuring the accurate execution of operations such as car starting and shifting.

[0003] To ensure the stability and reliability of the automotive electrical system, the automotive electromagnetic switch coil must be able to provide continuous and stable signal transmission and sufficient power supply for the entire system. This requires that the winding operation must achieve extremely high precision during the coil manufacturing process to ensure that the electrical and mechanical properties of the coil meet the design requirements.

[0004] However, most current coil winding equipment is only equipped with a single winding station. For example, a coil winding equipment with publication number CN118538533A can meet the high-precision winding requirements of coils to a certain extent. However, in actual production, after each coil is wound, the coil mold frame needs to be replaced for a long time when preparing for the next coil winding. This makes it impossible to achieve continuous operation and is difficult to meet the needs of large-scale production.

[0005] Moreover, it does not have the function of automatically fixing the wire ends after the coil is replaced, so during the rapid winding process of multiple coil molds, manual assistance is required to fix the wire ends, which increases the difficulty of operation and the probability of error, further limiting the improvement of production efficiency and making it difficult to meet the requirements of the automotive manufacturing industry for efficient and high-quality coil production.

[0028] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1-Figure 7 As shown, the problems in the prior art such as the long replacement cycle of coil mold frames, the inability to achieve continuous operation, the difficulty in meeting the needs of large-scale production, and the lack of automatic fixing of the wire ends after coil replacement can be solved by the following solution;

[0030] In this embodiment, a device for winding and forming an automotive electromagnetic switch coil is obtained, comprising a base 1, and a multi-station winding assembly 2 and a discharge assembly 3 arranged on the base 1. The multi-station winding assembly 2 comprises a fixed plate 21 welded to the top of the base 1, a rotating shaft is rotatably mounted on the fixed plate 21, and a mounting plate 22 is fixedly connected to the rotating shaft. Rotating rods 23 are rotatably mounted on both sides of the mounting plate 22. The rotating shaft and the mounting plate 22 are provided to switch the two rotating rods 23, thereby realizing the alternating use of multiple stations, achieving the simultaneous replacement of coils during winding, and thus achieving the effect of improving processing efficiency.

[0031] The rotating rod 23 is fixedly connected to a limit plate 24 that assists in the installation and positioning of the coil mold frame, and is provided with multiple groups of inner clamping plates 25 distributed in a ring array for clamping the coil mold frame. The coil mold frame is clamped and fixed by the diverging movement of the multiple inner clamping plates 25.

[0032] A number of wire clamping grooves are provided on the annular outer wall of the limiting plate 24, and an elastic wire clamping block 26 is fixedly installed in the wire clamping groove. The end of the wire on the wire pay-off frame is clamped on an elastic wire clamping block 26 on the corresponding limiting plate 24. The servo motor 2 drives the corresponding rotating rod 23 to rotate, and then drives the coil mold frame to rotate for winding. A cutter 27 for cutting the wire is installed on the rotating shaft, which is used for cutting the wire between the two coil mold frames.

[0033] A servo motor 1 for driving the rotating shaft is installed on the fixing plate 21 by bolts, and a servo motor 2 for driving the corresponding rotating rod 23 is installed on the mounting plate 22 by bolts. The end of the rotating shaft is fixedly connected to a wire plate 28.

[0034] The wire guide 28 includes a tangent portion that cooperates with the cutter 27, and a wire guide portion fixedly connected to both sides of the tangent portion and arranged obliquely. The tangent portion is located between the limit plate 24 and the mounting plate 22, and the end of the wire guide portion is located on the side of the limit plate 24 away from the mounting plate 22. After completing the winding of the coil mold on one side, the servo motor drives the rotating shaft carrying the mounting plate 22 to deflect 180 degrees, switching the positions of the two rotating rods 23.

[0035] During the deflection conversion process, a section of the unwound wire on the coil mold frame is guided by the wire portion on one side and placed between the tangent portion and the mounting plate 22. Combined with the position of the wire seat 36 located on the side of the screw 35 away from the servo motor 3, the wire section is clamped in the corresponding elastic wire clamping block 26 on the two sets of limit plates 24, thereby automatically completing the fixing of the two ends after tangent.

[0036] The rotating rod 23 is internally rotatably connected to a bidirectional screw rod 29. The free end of the bidirectional screw rod 29 extends to the outside of the rotating rod 23 and is fixed with a torsion wheel for realizing the rotation of the bidirectional screw rod 29. The bidirectional screw rod 29 is symmetrically threaded with a moving block 210 that slides with the rotating rod 23. A support rod 211 is hinged between each inner clamping plate 25 and the moving block 210, and the support rod 211 is slidably connected to the rotating rod 23.

[0037] The coil mold frame is placed on one side of the rotating rod 23 and contacts the limit plate 24. The rotating torsion wheel drives the bidirectional screw 29 to rotate, prompting the two groups of moving blocks 210 to move relative to each other. Combined with the support rod 211, multiple inner clamping plates 25 are moved away from each other, and coil mold frames of different sizes are adaptively centered and clamped.

[0038] A ring 212 is fixedly connected to one side of the cutter 27 and slides with the rotating shaft. A spring telescopic rod 213 is fixedly connected between the ring 212 and the mounting plate 22. The spring telescopic rod 213 is used to ensure stable sliding of the ring 212 and to quickly reset the cutter 27 after the protrusion 1 214 and the protrusion 2 215 are separated.

[0039] Two sets of protrusions 1 214 are symmetrically fixedly connected to one side of the circular ring 212, and two sets of protrusions 2 215 that cooperate with the protrusions 1 214 are fixedly connected to the fixed plate 1 21. The rotation of the cutter 27 carried by the rotating shaft causes the protrusions 1 214 to contact the protrusions 2 215, pushing the circular ring 212 carrying the cutter 27 to move, and cooperating with the tangent part to cut the wire between the two rotating rods 23.

[0040] The unwinding assembly 3 includes a second fixing plate 31 welded to the top of the base 1, and a rotating rod 32 is mounted on the second fixing plate 31 in a damped rotation manner. The damped rotation installation of the rotating rod 32 prevents the rotating rod 32 from continuing to rotate when the coil mold frame stops rotating, thereby causing the wire on the wire pay-off frame to become loose and explode, making subsequent unwinding inconvenient. The rotating rod 32 is fixedly connected to a first tapered chuck 33 and is threadedly connected to a second tapered chuck 34.

[0041] The pay-off frame is plugged into the rotating rod 32, and the conical chuck 2 34 is threadedly installed on the rotating rod 32. During the installation process, the pay-off frame is adaptively centered and clamped by the conical surfaces of the conical chuck 1 33 and the conical chuck 2 34 to avoid shaking during rotation.

[0042] The second fixing plate 31 is rotatably connected to a screw rod 35 and fixedly connected to a slide rod. The slide rod is slidably connected to a wire holder 36 threadedly connected to the screw rod 35. The wire holder 36 is provided with a wire sleeve 37. A graphite sleeve is installed inside the wire sleeve 37 via bolts to protect the conveyed wire and reduce wear on the wire.

[0043] A servo motor three is installed on the fixed plate 31 through bolts to drive the screw 35 to rotate. The coil mold frame rotates to wind the wire, and the wire between the pay-off frame and the coil mold frame is straightened. The servo motor three drives the screw 35 to rotate forward and reverse, prompting the wire seat 36 to drive the wire sleeve 37 to move back and forth, and the auxiliary wire is evenly distributed and wound on the coil mold frame.

[0044] A movable seat 38 is provided on the top of the wire holder 36 and is rotatably connected to the wire sleeve 37. T-shaped blocks are symmetrically fixed on both sides of the bottom of the movable seat 38. A T-shaped slot is provided on the wire holder 36 and slides with the T-shaped block. The sliding installation of the movable seat 38 is achieved through the cooperation of the T-shaped block and the T-shaped slot.

[0045] During the coil winding process of an automobile electromagnetic switch, the height and inclination of the wire sleeve 37 can be automatically and adaptively adjusted as the radius of the coil on the pay-off frame gradually decreases and the radius on the coil die frame gradually increases, thereby guiding the winding distribution of the wire. At the same time, the gravity of the wire sleeve 37 and the movable seat 38 is relied upon to automatically adjust the tension of the conveyed wire, and combined with the graphite sleeve inside the wire sleeve 37, the wear on the wire is reduced.

[0046] Example 2: Please refer to Figure 1-Figure 7 As shown, the present invention also provides a method for using an automobile electromagnetic switch coil winding forming device, comprising the following steps:

[0047] Step 1: Insert the pay-off stand onto the rotating rod 32, and thread the conical chuck 2 34 onto the rotating rod 32. During the installation process, the pay-off stand is adaptively centered and clamped by the conical surfaces of the conical chuck 1 33 and the conical chuck 2 34 to avoid shaking during the rotation process. A set of coil mold frames is set on one side of the rotating rod 23 and contacts the limit plate 24. The torsion wheel is rotated to drive the bidirectional screw rod 29 to rotate, so as to promote the relative movement of the two sets of moving blocks 210. Combined with the support rod 211, the multiple inner clamping plates 25 are moved away from each other, and the coil mold frame 1 is adaptively centered and clamped;

[0048] Step 2: After the end of the wire on the pay-off frame is passed through the wire sleeve 37 and clamped on an elastic wire clamping block 26 on the corresponding limit plate 24, the servo motor 2 drives the corresponding rotating rod 23 to rotate, thereby driving the coil mold frame 1 to rotate for winding and rewinding, and the rotating rod 32 rotates in a damped manner. Through the sliding connection between the wire seat 36 and the movable seat 38, the wire sleeve 37 rises, and the wire between the pay-off frame and the coil mold frame 1 is straightened. The servo motor 3 drives the screw 35 to rotate forward and reverse, prompting the wire seat 36 to drive the wire sleeve 37 to move back and forth, assisting the wire to be evenly distributed and rewound on the coil mold frame 1, and the coil mold frame 2 is installed synchronously during the winding process;

[0049] Step 3: After the coil mold frame 1 is wound, it stops rotating. The servo motor 1 drives the rotating shaft carrying the mounting plate 22 to deflect 180 degrees, switching the positions of the two rotating rods 23. During the deflection and switching process, the unwound section of the wire on the coil mold frame 1 is guided by the wire portion on one side and placed between the tangent portion and the mounting plate 22. In combination with the wire holder 36 located on the side of the screw 35 away from the servo motor 3, the wire section is clamped on the corresponding elastic wire clamping blocks 26 on the two sets of limit plates 24.

[0050] Step 4: The rotation of the cutter 27 carried by the rotating shaft causes the protrusion 1 214 to contact the protrusion 2 215, pushing the ring 212 carrying the cutter 27 to move, and cooperating with the tangent part to cut the wire between the two rotating rods 23. At this time, the corresponding servo motor 2 drives the coil mold frame 2 to rotate, and the elastic wire clamping block 26 on the corresponding limit plate 24 fixes the wire end to wind the wire. In this process, the coil mold frame 1 is disassembled and the coil mold frame 2 is replaced to quickly complete the replacement of the coil mold frame and achieve efficient winding and molding of the electromagnetic switch coil.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
