Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy vehicle parts manufacturing technology, and in particular to a wire laying stabilization device for enameled aluminum wire used in new energy vehicles. Background Technology
[0002] New energy vehicle component manufacturing technology is a technical system for producing core components and supporting parts such as motors and electronic controls for new energy vehicles, meeting the performance and energy efficiency requirements of vehicles. In the project "Research and Development of Enameled Aluminum Wire Preparation Process for New Energy Vehicles," this wire-laying stabilization device was designed to address the problems of loosening, displacement, and low rewinding efficiency of the prepared enameled aluminum wire during subsequent processing, ensuring processing accuracy and the effective application of research results.
[0003] Under current conditions, a common practice is to use a wire winding and unwinding support, as disclosed in CN208700253U, which includes a base, a frame, a ring frame, a ring cover plate, and connecting clamps. This not only improves the working efficiency of the unwinding support but also prevents the enameled wire from peeling off during the unwinding process. However, the enameled wire winding in this device is installed on an internal anti-slip support and is sealed and fixed by the ring cover plate, connecting clamps, and fastening bolts. When the wire roll needs to be replaced, the fastening bolts need to be loosened, the clamps need to be released, and the entire ring cover plate needs to be removed, which is time-consuming and reduces production efficiency. This device uses a one-way telescopic rod and rollers to press the enameled wire onto the soft pad groove, and its tension depends entirely on the rotation of the motor and the static friction between the enameled wire and the soft pad groove. When the unwinding speed or the weight of the wire roll changes, problems such as wire loosening, accumulation, knotting, or even breakage can easily occur. Utility Model Content
[0004] The purpose of this invention is to solve the problem of easy loosening of enameled aluminum wires used in new energy vehicles during the wire laying process in the prior art, and to propose a wire laying stabilization device for enameled aluminum wires used in new energy vehicles.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wire unwinding and stabilizing device for enameled aluminum wire used in new energy vehicles includes a workbench. Two symmetrically arranged unwinding frames and winding frames are fixedly installed on the workbench. An unwinder for releasing aluminum wire is placed between the two unwinding frames, and a winding device for winding aluminum wire is placed between the two winding frames. Limiting structures for limiting the unwinder and winding device are respectively provided on the unwinding frames and winding frames. A tensioning structure for tightening aluminum wire is provided on the workbench.
[0006] Preferably, the unwinder consists of a rotating shaft, an unwinding roller, and a baffle, and the rewinder consists of a rotating shaft, a rewinding roller, and a baffle. The unwinding frame and the rewinding frame are provided with limiting holes for limiting the rotation of the rotating shaft.
[0007] Preferably, the limiting structure includes two movable rods that are slidably sleeved on the unwinding frame and the winding frame, and a limiting block for limiting the unwinder and the winding device is fixedly installed on the movable rod. A U-shaped block is fixedly installed at one end of the movable rod, and a transmission frame is installed on the inner pin of the unwinding frame and the winding frame. The unwinding frame and the winding frame are slidably fitted with lifting rods, and the upper end of the lifting rod is fixedly installed with a contact block that moves against the rotating shaft. A spring is welded between the unwinding frame, the winding frame and the lifting rod. A lifting frame that moves against the two transmission frames is fixedly installed on the lifting rod.
[0008] Preferably, the transmission frame has an L-shaped structure, and the unwinding frame and the winding frame are respectively equipped with limiting frames for repositioning the unwinder and the winding device. Magnetic blocks with opposite poles attracting each other are embedded between the unwinding frame, the winding frame and the limiting frames.
[0009] Preferably, the tensioning structure includes two pressure-applying frames and an adjusting frame fixedly installed on the workbench. A pressure-applying block is slidably sleeved inside the pressure-applying frame. A positioning block 1 extending out of the pressure-applying frame is fixedly installed on the pressure-applying block. A pressure roller for applying pressure to the aluminum wire is placed between the two positioning blocks 1. A spring 2 is welded between the pressure-applying block and the pressure-applying frame. A threaded rod is slidably sleeved on the adjusting frame, and an adjusting block is rotatably installed at the lower end of the threaded rod. A positioning block two extending outside the adjusting frame is fixedly installed on the adjusting block, and an adjusting roller that cooperates with the pressure roller is placed between the two positioning blocks two.
[0010] Preferably, the positioning block one and positioning block two are respectively provided with limiting grooves for limiting the pressure roller and the adjusting roller, and the adjusting frame is provided with threaded holes that match the threaded rod.
[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model places the unwinder in the upper limit hole of the unwinding frame, and the unwinder contacts and presses against the contact block. The contact block drives the lifting rod to press against the spring. At the same time, the contact block drives the lifting frame to move down synchronously through the lifting rod, so that the transmission frame rotates around the pin. The transmission frame presses against the inner wall of the return block, thereby driving the limit block to limit the unwinder. Rotating the limit frame further limits the unwinder, realizing the quick replacement of the unwinder and rewinder without the need for tools, saving replacement time and helping to improve work efficiency.
[0012] 2. This utility model involves passing the aluminum wire through the lower surface of the pressure roller and then through the upper surface of the adjusting roller. The aluminum wire is then wound up using a winding device. Rotating the two threaded rods causes the adjusting block to move upward. The adjusting block applies upward pressure to the aluminum wire through the second limiting block and the adjusting roller. The aluminum wire under pressure contacts the pressure roller and applies pressure to it. The pressure roller applies pressure to the second spring through the first limiting block and the pressure block. At this time, the aluminum wire is in a taut state, preventing the aluminum wire from becoming loose during the unwinding process and ensuring the stability of the unwinding and winding process.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Reference Figures 1-5 A wire unwinding and stabilizing device for enameled aluminum wire used in new energy vehicles includes a workbench 1. Two symmetrically arranged unwinding frames 2 and winding frames 4 are fixedly installed on the workbench 1. An unwinder 3 for releasing aluminum wire is placed between the two unwinding frames 2, and a winding device 5 for winding aluminum wire is placed between the two winding frames 4.
[0017] The unwinding frame 2 and the winding frame 4 are respectively equipped with limiting structures to limit the position of the unwinder 3 and the winding device 5. The limiting structures effectively restrict the position of the unwinder 3 and the winding device 5 during operation, preventing them from shifting or shaking due to rotation or external force, ensuring the stable operation of the unwinding and winding work. At the same time, it enables quick replacement of the unwinder 3 and the winding device 5, which helps to improve work efficiency.
[0018] The workbench 1 is equipped with a tensioning structure to tighten the aluminum wire. The tensioning structure adjusts the tension of the aluminum wire according to the actual work requirements to avoid problems such as loosening or tangling of the aluminum wire during the wire feeding process, and to ensure that the aluminum wire is always transmitted in a stable state.
[0019] The unwinder 3 consists of a rotating shaft, an unwinding roller, and a baffle. The rewinder 5 consists of a rotating shaft, a rewinding roller, and a baffle. Both the unwinding roller and the rewinding roller are used to wind aluminum wire. The baffle acts as a barrier to prevent the aluminum wire from slipping off the sides of the roller during the winding process. The unwinding frame 2 and the rewinding frame 4 are provided with limiting holes for limiting the rotating shaft. The size of the limiting holes matches the rotating shaft of the unwinder 3 and the rewinder 5. After the rotating shaft is placed in the limiting holes, the unwinder 3 and the rewinder 5 are initially positioned.
[0020] The limiting structure includes two sliding rods 6 that are slidably sleeved on the unwinding frame 2 and the winding frame 4, and a limiting block 7 that limits the unwinder 3 and the winding device 5 is fixedly installed on the sliding rods 6. The limiting block 7 is an arc-shaped structure that is adapted to the rotating rod. It is made of wear-resistant rubber material, which not only ensures the limiting effect, but also avoids wear on the rotating shafts of the unwinder 3 and the winding device 5. A return block 8 is fixedly installed at one end of the sliding rod 6, and a transmission frame 9 is installed on the inner pin shaft of the unwinding frame 2 and the winding frame 4. A lifting rod 10 is slidably sleeved inside the unwinding frame 2 and the winding frame 4, and an abutment block 11 that moves against the rotating shaft is fixedly installed on the upper end of the lifting rod 10. The surface of the abutment block 11 is smoothed to reduce the friction when in contact with the rotating shaft. A spring 12 is welded between the unwinding frame 2, the winding frame 4 and the lifting rod 10 respectively. A lifting frame 13 that moves against the two transmission frames 9 is fixedly installed on the lifting rod 10.
[0021] The transmission frame 9 has an L-shaped structure. The unwinding frame 2 and the winding frame 4 are respectively equipped with a limiting frame 14 for re-limiting the unwinder 3 and the winding device 5. After the unwinder 3 and the winding device 5 are initially limited, the limiting frame 14 is rotated to make it contact the rotating shaft, which further improves the limiting effect and prevents the unwinder 3 and the winding device 5 from loosening when rotating at high speed.
[0022] A magnetic block with opposite poles is embedded between the unwinding frame 2, the winding frame 4 and the limiting frame 14. The attraction of the magnetic block keeps the limiting frame 14 stably in the limiting position, preventing it from rotating on its own during operation and losing its limiting function.
[0023] The tensioning structure includes two pressure frames 15 and an adjusting frame 20 fixedly installed on the workbench 1. A pressure block 16 is slidably sleeved inside the pressure frame 15. Two guide blocks extending into the pressure frame 15 are fixedly installed on the pressure block 16 to prevent the pressure block 16 from shifting during movement. A positioning block 18 extending out of the pressure frame 15 is fixedly installed on the pressure block 16, and a pressure roller 19 for applying pressure to the aluminum wire is placed between the two positioning blocks 18.
[0024] A second spring 17 is welded between the pressure block 16 and the pressure frame 15. When the pressure roller 19 moves downward under the reaction force of the aluminum wire, the second spring 17 is further compressed, and at the same time, an upward elastic force is generated. This force is transmitted to the pressure roller 19 through the pressure block 16 and the positioning block 18, so that the pressure roller 19 continuously applies pressure to the aluminum wire.
[0025] A threaded rod 21 is slidably sleeved on the adjusting frame 20, and an adjusting block 22 is rotatably installed at the lower end of the threaded rod 21. The adjusting block 22 and the threaded rod 21 are connected by a bearing, so that when the threaded rod 21 rotates, the adjusting block 22 only moves up and down and does not rotate with the threaded rod 21. A positioning block 23 extending outside the adjusting frame 20 is fixedly installed on the adjusting block 22, and an adjusting roller 24 that cooperates with the pressure roller 19 is placed between the two positioning blocks 23. By rotating the threaded rod 21, the adjusting block 22, the positioning block 23 and the adjusting roller 24 move up and down, adjusting the vertical distance between the adjusting roller 24 and the pressure roller 19, thereby changing the pressure on the aluminum wire and realizing the adjustment of the tension of the aluminum wire.
[0026] Positioning block 18 and positioning block 23 are respectively provided with limiting grooves to restrict the pressure roller 19 and the adjusting roller 24. The shape and size of the limiting grooves are matched with the two ends of the pressure roller 19 and the adjusting roller 24, which effectively prevents the pressure roller 19 and the adjusting roller 24 from being displaced during rotation and ensures their working stability. The adjusting frame 20 is provided with threaded holes that match the threaded rod 21.
[0027] The functional principle of this utility model can be explained through the following operation methods: Place the shaft of the unwinder 3 into the limiting hole on the unwinder frame 2, and at the same time place the shaft of the rewinder 5 into the limiting hole on the rewinder frame 4. The shaft of the unwinder 3 contacts the abutment block 11 and applies pressure to it. The abutment block 11 drives the lifting rod 10 to apply pressure to the spring 12. At the same time, the lifting rod 10 drives the lifting frame 13 to move down synchronously. The lifting frame 13 applies pressure to one end of the transmission frame 9, causing the transmission frame 9 to rotate around the pin. The other end of the transmission frame 9 applies pressure to the inner wall of the return block 8, causing the return block 8 to drive the moving rod 6 to move. The moving rod 6 drives the limiting block 7 to initially limit the unwinder 3. Rotate the limiting frame 14 so that the limiting frame 14 contacts the rotating shaft of the unwinder 3. The opposite pole attracting magnetic blocks embedded between the limiting frame 14 and the unwinder 2 attract each other, further limiting the unwinder 3. Repeat the above steps to complete the limiting installation of the rewinder 5 on the rewind rack 4; Pass one end of the enameled aluminum wire on the unwinder 3 through the lower surface of the pressure roller 19, then around the upper surface of the adjusting roller 24, and use the rewinder 5 to rewind it. The two threaded rods 21 on the rotating adjustment frame 20 rotate in the threaded holes of the adjustment frame 20 and drive the adjustment block 22 to move upward. The adjustment block 22 drives the positioning block 23 to move upward synchronously. The positioning block 23 drives the adjustment roller 24 to move upward. The adjustment roller 24 applies upward pressure to the aluminum wire. The stressed aluminum wire applies downward pressure to the lower surface of the pressure roller 19. The pressure roller 19 drives the positioning block 18 to move downward, and the positioning block 18 drives the pressure block 16 to move downward. The pressure block 16 applies pressure to the spring 17, and the aluminum wire is in a taut state at this time. During the winding and unwinding process, the elastic force of spring 17 is transmitted to pressure roller 19 through pressure block 16 and positioning block 18, continuously applying downward pressure to the aluminum wire. Combined with the upward pressure of adjusting roller 24, the aluminum wire is always kept taut. When it is necessary to replace the unwinder 3 or the take-up 5, rotate the limit frame 14 in the reverse direction to disconnect the limit frame 14 from the shaft of the unwinder 3 or the take-up 5. Lift the unwinder 3 or the rewinder 5 upwards to separate its shaft from the contact block 11. The spring 12 returns to its original shape, causing the lifting rod 10 to move upwards. The lifting rod 10 drives the transmission frame 9 to rotate in the opposite direction through the lifting frame 13. The transmission frame 9 applies pressure to the inner wall of the return block 8. The moving rod 6 drives the limiting block 7 to move away from the unwinder 3 or the rewinder 5. Once the limiting is released, the old unwinder 3 or the rewinder 5 can be removed.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
