Technical Field
[0001] This utility model belongs to the field of coil stripping technology, specifically a rapid coil lead stripping machine. Background Technology
[0002] A coil is a conductive component consisting of insulated wires such as enameled wire and PVC insulated wire wound on an insulating skeleton such as plastic or ceramic in a specific number of turns and arrangement. It is widely used in equipment such as transformers, motors, inductors, and relays. Its core function is to convert electrical energy into magnetic energy by generating magnetism through current or inducing electricity through magnetic field. The coil lead is a wire that extends from the beginning and end of the coil winding. It serves as a bridge connecting the coil to the external circuit and is usually reserved with a length of 5-20mm to meet the connection requirements. Because the outer layer of the insulated wire has an insulating layer such as polyurethane varnish or PVC, directly connecting the lead wire with the insulating layer to the external circuit will cause an open circuit and prevent the lead wire from making effective contact with external components (such as solder joints and terminals). Therefore, it is necessary to strip the outer insulation layer of the coil lead wire to expose the internal metal conductors such as copper and aluminum wires. This ensures a stable connection between the lead wire and the external circuit and guarantees normal power supply to the equipment. At the same time, precise stripping can avoid faults such as poor contact and short circuits caused by residual insulation layer.
[0003] Currently, most coil lead stripping operations still rely on manual operation by operators using simple wire strippers. This method is not only labor-intensive and inefficient, but also relies entirely on personal experience for the stripping depth, which can easily lead to quality problems such as insulation residue, wire core scratches or cuts, making it difficult to guarantee product consistency. Although some automated stripping mechanisms are used, their stripping molds usually need to be adjusted or replaced for specific wire diameters, lacking the ability to quickly adapt to various lead diameters and having poor versatility. Therefore, a rapid coil lead stripping machine is provided. Utility Model Content
[0004] The purpose of this invention is to provide a rapid stripping machine for coil leads in order to solve the problems mentioned above.
[0005] The technical solution adopted by this utility model is as follows: A rapid stripping machine for coil leads includes a housing. An inlet hole is provided near the center of the top surface of the housing. A hollow tube is disposed inside the housing. Multiple mounting rods are hinged to the inner wall of the hollow tube near its top end, and stripping blades are provided at the ends of the mounting rods that are close to each other. A conical column is disposed inside the hollow tube. Multiple connecting rods are hinged to the outer surface of the conical column. The end of each connecting rod away from the conical column is hinged to one side of a mounting rod. Limiting devices are symmetrically provided on the outer surface of the hollow tube. A second mounting rod is symmetrically fixedly installed on the outer surface of the conical column. One end of the second mounting rod passes through the interior of the limiting hole and extends to the exterior of the hollow tube. A circular ring is fixedly installed on the end of the second mounting rod away from the conical column. A rectangular plate is provided on the outer surface of the circular ring. A limiting plate is fixedly installed on the top and bottom surfaces of the rectangular plate by bolts. An electric push rod is provided on the bottom surface of the rectangular plate. The telescopic end of the electric push rod is fixed to the bottom surface of the rectangular plate. A drive rotation mechanism connected to the hollow tube is provided inside the outer shell.
[0006] In a preferred embodiment, the drive rotation mechanism includes a fixed plate, a drive motor, a pinion, and a large gear. The fixed plate is located near the bottom of the outer casing. The bottom end of the electric push rod is fixed to the top surface of the fixed plate. The drive motor is fixedly mounted on the top surface of the fixed plate. The pinion is fixedly mounted on the drive end of the drive motor. The large gear is fixedly mounted on the outer surface of the hollow tube. The pinion and the large gear are meshed together.
[0007] In a preferred embodiment, a fixing frame is fixedly installed near the bottom inner wall of the outer shell, and multiple fixing bolts are movably inserted through the bottom surface of the fixing plate near the corners, and all of the multiple fixing bolts are threadedly connected to the fixing frame.
[0008] In a preferred embodiment, a bearing seat is fixedly installed on the top surface of the fixing plate near the center, and the bottom end of the hollow tube is fixedly installed in the center of the bearing seat.
[0009] In a preferred embodiment, a collection box is fixedly installed on the bottom surface of the outer shell by two bolts, and a feed hole corresponding to the hollow tube is opened on the top surface of the collection box near the middle.
[0010] In a preferred embodiment, a limiting rod is movably inserted through the top surface of the rectangular plate, and the bottom end of the limiting rod is fixed to the top surface of the fixed plate.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, due to the adoption of the above-mentioned solution, the user first inserts the coil lead into the hollow tube through the inlet hole on the top surface of the outer shell, and then starts the electric push rod. The electric push rod drives the rectangular plate to move vertically along the limiting rod, and simultaneously drives the limiting plate, the circular ring and the mounting rod to move, thereby pushing the conical column to move along the axis inside the hollow tube. When the conical column moves, it drives the mounting rod to rotate around the hinge point through the connecting rod, adjusting the stripping blade spacing. During this process, the strain gauge sensor detects the blade pressure in real time. When the spacing matches the lead diameter and the pressure reaches the preset value, the electric push rod stops. Then, the drive motor starts, and through gear meshing, it drives the hollow tube to rotate around the bearing seat. The hollow tube drives the stripping blade to rotate synchronously, uniformly cutting the lead outer sheath to achieve stripping. The stripping waste falls down along the hollow tube under the action of gravity. This device can automatically adjust the blade spacing to adapt to lead wires of different diameters, and together with the drive mechanism, it improves stripping efficiency and accuracy and reduces manual labor intensity.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] refer to Figures 1-7 As shown, a rapid coil lead stripping machine includes a housing 1. A collection box 18 is fixedly installed on the bottom surface of the housing 1 by two bolts. The top surface of the collection box 18 has a feed hole 19 corresponding to the hollow tube 3 near the center. The two bolts allow for a detachable connection between the collection box 18 and the housing 1, facilitating the subsequent cleaning or replacement of the stripping waste collected inside the collection box 18. The feed hole 19, corresponding to the hollow tube 3, ensures that the lead sheath that falls off inside the hollow tube 3 falls accurately into the collection box 18, preventing waste from scattering inside the housing 1 and making it difficult to clean, maintaining the cleanliness of the device's interior, and reducing the interference of waste accumulation on the device's operation.
[0022] refer to Figures 1-7 As shown, the top surface of the outer casing 1 has an inlet hole 2 near the center. A hollow tube 3 is installed inside the outer casing 1. Multiple mounting rods 4 are hinged to the inner wall of the hollow tube 3 near its top, and each mounting rod 4 has a stripping blade 5 at one end close to the others. A conical column 6 is installed inside the hollow tube 3, and multiple connecting rods 7 are hinged to the outer surface of the conical column 6. The end of the connecting rod 7 away from the conical column 6 is hinged to one side of the mounting rod 4. The inlet hole 2 provides a precise entry channel for the coil lead, ensuring that the lead can smoothly extend into the hollow tube 3 for stripping. The mounting rods 4 and the conical column 6 are hinged together via the connecting rods 7 to form a linkage structure. Subsequently, the installation rod 4 can be rotated by the movement of the conical column 6, thereby adjusting the spacing of the peeling blades 5 to adapt to coil leads of different diameters and improve the versatility of the device. A groove is opened at one end of multiple installation rods 4. The peeling blades 5 are installed by combining the grooves, straight slots and locking bolts, which can not only achieve stable positioning, but also adjust the position of the peeling blades 5 or replace the blades by loosening the locking bolts, reducing maintenance costs. Furthermore, a strain gauge sensor is set inside the groove and contacts the peeling blades 5 to detect the pressure on the peeling blades 5 in real time, avoiding damage to the lead conductor due to excessive pressure or incomplete peeling due to insufficient pressure, thus improving peeling accuracy and safety.
[0023] refer to Figures 1-7As shown, symmetrical limiting holes 8 are formed on the outer surface of the hollow tube 3. A second mounting rod 9 is symmetrically fixedly installed on the outer surface of the conical column 6. One end of the second mounting rod 9 passes through the interior of the limiting hole 8 and extends to the exterior of the hollow tube 3. A circular ring 10 is fixedly installed on the end of the second mounting rod 9 away from the conical column 6. A rectangular plate 11 is provided on the outer surface of the circular ring 10. Limiting discs 12 are fixedly installed on the top and bottom surfaces of the rectangular plate 11 by bolts. An electric push rod 13 is provided on the bottom surface of the rectangular plate 11, and the telescopic end of the electric push rod 13 is fixed to the bottom surface of the rectangular plate 11. A drive rotation mechanism 14 connected to the hollow tube 3 is provided inside the outer casing 1. The limiting hole 8 provides a guide for the movement of the second mounting rod 9, preventing deviation when the second mounting rod 9 moves the conical column 6, ensuring stable movement of the conical column 6 along the axis of the hollow tube 3, thereby ensuring precise adjustment of the peeling blade 5 spacing. The circular ring 10 connects the two second mounting rods 9 into a whole, allowing the conical column 6 to move up and down synchronously under the drive of the second mounting rods 9. This avoids uneven adjustment of the peeling blade 5 due to unilateral offset. The rectangular plate 11 is fixed to the limiting plate 12 by bolt 1. The limiting plate 12 can limit the circular ring 10, facilitating the subsequent rotation of the circular ring 10. At the same time, it can also prevent the circular ring 10 from detaching from the rectangular plate 11 during rotation and movement. The detachable design of bolt 1 facilitates subsequent maintenance of components such as the circular ring 10 and the second mounting rods 9. The top surface of the circular ring 10 is provided with a wear-resistant layer to reduce wear during subsequent rotation. The electric push rod 13 provides stable power for the up and down movement of the rectangular plate 11, the circular ring 10, and the conical column 6, improving the automation and efficiency of the peeling blade 5 spacing adjustment.
[0024] refer to Figures 1-7As shown, the drive rotation mechanism 14 includes a fixed plate 1401, a drive motor 1402, a pinion 1403, and a large gear 1404. The fixed plate 1401 is located near the bottom of the outer casing 1. A fixed frame 15 is fixedly installed on the inner side wall of the outer casing 1 near the bottom. Multiple fixing bolts 16 are movably inserted through the bottom surface of the fixed plate 1401 near its corners, and all fixing bolts 16 are threadedly connected to the fixed frame 15. The bottom end of the electric push rod 13 is fixed to the top surface of the fixed plate 1401. A limiting rod 20 is movably inserted through the top surface of the rectangular plate 11, and the bottom end of the limiting rod 20 is fixed to the top surface of the fixed plate 1401. A bearing seat 17 is fixedly installed near the center of the top surface of the fixed plate 1401, and the bottom end of the hollow tube 3 is fixedly installed in the center of the bearing seat 17. Through the fixed plate 1401... It is connected to the fixing frame 15 by fixing bolts 16, so as to achieve stable fixation of the fixing plate 1401 in the outer shell 1. At the same time, the threaded connection of the fixing bolts 16 facilitates the subsequent disassembly of the fixing plate 1401, so as to inspect or replace the electric push rod 13, drive motor 1402 and other components mounted on its top surface. The setting limit rod 20 can guide the movement of the rectangular plate 11, prevent the rectangular plate 11 from shifting laterally under the drive of the electric push rod 13, and ensure that the rectangular plate 11 moves stably in the vertical direction, thereby ensuring the stability of the movement of the tapered column 6. The setting bearing seat 17 provides stable support for the hollow tube 3, while reducing the friction between the hollow tube 3 and the fixing plate 1401 when the hollow tube 3 rotates, reducing component wear, and ensuring the coaxiality of the hollow tube 3 when rotating, thus improving the stability of the peeling operation.
[0025] refer to Figures 1-7 As shown, a drive motor 1402 is fixedly installed on the top surface of the fixed plate 1401. A small gear 1403 is fixedly installed on the drive end of the drive motor 1402, and a large gear 1404 is fixedly installed on the outer surface of the hollow tube 3. The small gear 1403 and the large gear 1404 are meshed and connected. The drive motor 1402 drives the hollow tube 3 to rotate through the meshing of the small gear 1403 and the large gear 1404. The gear transmission has the characteristics of high transmission efficiency, precise transmission ratio and stable operation, which can ensure that the hollow tube 3 rotates at a stable speed, thereby driving the peeling blade 5 to uniformly cut the outer sheath of the coil lead, improving the peeling effect. At the same time, the combination of the small gear 1403 and the large gear 1404 can realize the deceleration transmission, so that the hollow tube 3 obtains a suitable rotation speed, avoiding damage to the lead due to excessive speed or affecting the peeling efficiency due to excessively slow speed.
[0026] The implementation principle of this utility model's rapid coil lead stripping machine is as follows: The user first inserts the coil lead into the hollow tube 3 through the inlet hole 2 on the top surface of the outer casing 1. Then, the electric push rod 13 is activated. The telescopic end of the electric push rod 13 drives the rectangular plate 11 to move vertically along the limiting rod 20. The movement of the rectangular plate 11 causes the limiting plate 12 and the circular ring 10 to move synchronously. The movement of the circular ring 10 causes the second mounting rod 9 to move along the limiting hole 8, thereby causing the conical column 6 to move along the axial direction within the hollow tube 3. At this time, through… The movement of the conical column 6 causes the connecting rod 7, which is hinged to its outer surface, to push the mounting rod 4 upward around the hinge point. This facilitates the connecting rod 7 to push the mounting rod 4 closer to the axis of the hollow tube 3, reducing the spacing between the multiple peeling blades 5. When the conical column 6 moves downward, the connecting rod 7 pulls the mounting rod 4 away from the axis, increasing the blade spacing. At this time, the peeling blades 5 will contact the lead wire sheath, and the pressure of the peeling blades 5 will be detected in real time by the strain gauge sensor until the blade spacing matches the lead wire diameter (the pressure reaches the preset value), at which point the electric push rod 13 stops working.
[0027] At this time, the drive motor 1402 starts, and the drive end of the drive motor 1402 drives the pinion 1403 to rotate. The pinion 1403 drives the large gear 1404 to rotate through meshing transmission. The large gear 1404 then drives the hollow tube 3 to rotate around the axis of the bearing seat 17. When the hollow tube 3 rotates, the mounting rod 4 inside it drives the stripping blade 5 to rotate synchronously, uniformly cutting the lead wire sheath to achieve lead wire stripping. The lead wire sheath waste generated during the stripping process falls down along the inside of the hollow tube 3 under the action of gravity and falls into the collection box 18 through the feed hole 19 on the top surface of the collection box 18 corresponding to the hollow tube 3. This device can effectively realize the automatic adjustment of the spacing between multiple stripping blades 5, so as to adapt to coil leads of different diameters. At the same time, in conjunction with the drive rotation mechanism 14, it can improve the stripping efficiency and accuracy and reduce the intensity of manual operation.
[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
