Description

Technical Field

[0001] This utility model relates to the field of tension structure technology, and in particular to a tension mechanism for rectangular enameled wire. Background Technology

[0002] Enameled wire is a type of electromagnetic wire made by coating an insulating enamel layer onto the surface of a copper or aluminum conductor and then curing it at high temperatures. It possesses excellent electrical insulation, heat resistance, and mechanical flexibility, and is widely used in winding coils for motors, transformers, and other applications. It comes in various types, such as easily solderable polyurethane enameled wire and high-temperature resistant polyimide enameled wire.

[0003] In the existing technology, during the process of collecting enameled wire, if the force on the enameled wire itself is too great, that is, if the tension is too high, the enameled wire itself is prone to becoming tighter, which can easily cause some damage to the enamel surface. If the tension between the enameled wire and each guide roller is too small, it is not easy to collect the enameled wire. Furthermore, due to the insufficient tension, the enameled wire is at risk of getting tangled with other devices during the collection process, which is not conducive to the overall collection of the enameled wire. Utility Model Content

[0004] The purpose of this invention is to provide a tensioning mechanism for rectangular enameled wire, which can adjust the tension of the enameled wire during the collection process, preventing the enameled wire from being pulled and damaged, and preventing the enameled wire from getting tangled with other devices, thus ensuring good collection of the enameled wire.

[0005] To achieve the above objectives, a tension mechanism for rectangular enameled wire is provided, comprising a first worktable, a fixed plate fixedly connected to the rear of the first worktable, a first roller rotatably connected to the upper left side of the fixed plate, a second roller rotatably connected to the upper left side of the middle of the fixed plate, a tension sensor fixedly connected to the lower left side of the fixed plate, a first motor fixedly connected to the upper middle of the fixed plate, a lead screw fixedly connected to the output end of the first motor, a nut block threadedly connected to the middle of the lead screw, an adjusting roller rotatably connected to the front of the nut block, a third motor fixedly connected to the right rear of the fixed plate, an insertion rod fixedly connected to the output end of the third motor, and a collecting cylinder disposed in front of the insertion rod;

[0006] A second workbench is fixedly connected to the right side of the first workbench, a microcontroller is fixedly connected to the top of the second workbench, and a servo driver is fixedly connected to the bottom of the second workbench.

[0007] According to the tensioning mechanism for a rectangular enameled wire, a third roller is rotatably connected to the upper right side of the first worktable, and a mortise roller is rotatably connected to the upper right side of the first worktable.

[0008] According to the tension mechanism of a rectangular enameled wire, a second motor is fixedly connected to the rear center of the fixed plate, and a guide roller is fixedly connected to the output end of the second motor.

[0009] According to the tension mechanism for a rectangular enameled wire, a support frame is fixedly connected to the middle of the first worktable, and the support frame is rotatably connected to the guide roller.

[0010] According to the tension mechanism of a rectangular enameled wire, a stabilizing rod is fixedly connected to the front right side of the fixing plate, and the stabilizing rod abuts against the collecting cylinder.

[0011] According to the tension mechanism of a rectangular enameled wire, a threaded block is fixedly connected to the front end of the insertion rod, and a locking nut is threadedly connected to the front of the threaded block.

[0012] According to the tension mechanism of a rectangular enameled wire, the inside of the collecting cylinder is provided with a through slot, which corresponds to the insertion rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, by incorporating a tension sensor, the real-time tension of the enameled wire can be sensed. The tension sensor is electrically connected to a microcontroller, which in turn is electrically connected to a servo driver. This allows the microcontroller to control the servo driver through its own program. Under the control of the microcontroller, the servo driver drives the first motor to rotate forward or backward. This achieves the adjustment of the tension of the rectangular enameled wire by its own tension, keeping the tension of the rectangular enameled wire within a stable range and ensuring good collection of the enameled wire.

[0016] 2. Compared with the existing technology, by setting up a second motor, which is electrically connected to the servo driver, and the servo driver is electrically connected to the microcontroller, the microcontroller can control the servo driver through its own program, thereby controlling the second motor. When the guide roller guides the enameled wire from the rear end to the front end, the second motor rotates in the opposite direction, causing the guide roller to guide the enameled wire from the front end to the rear end again. This cycle is repeated to achieve better collection of the enameled wire. Attached Figure Description

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-5This utility model provides a tension mechanism for rectangular enameled wire, comprising a first worktable 1, a fixed plate 2 fixedly connected to the rear of the first worktable 1, a first roller 3 rotatably connected to the upper left side of the fixed plate 2, a second roller 4 rotatably connected to the upper left side of the middle of the fixed plate 2, a tension sensor 5 fixedly connected to the lower left side of the fixed plate 2, a first motor 6 fixedly connected to the upper middle of the fixed plate 2, a lead screw 7 fixedly connected to the output end of the first motor 6, a nut block 8 threadedly connected to the middle of the lead screw 7, an adjusting roller 9 rotatably connected to the front of the nut block 8, a third motor 15 fixedly connected to the right rear of the fixed plate 2, an insertion rod 16 fixedly connected to the output end of the third motor 15, and the front end of the insertion rod 16... A threaded block 17 is fixedly connected, and a locking nut 20 is threadedly connected to the front of the threaded block 17. A collecting cylinder 18 is provided in front of the insert rod 16. A slot 19 is opened through the inside of the collecting cylinder 18, and the slot 19 corresponds to the insert rod 16. A second workbench 22 is fixedly connected to the right side of the first workbench 1. A microcontroller 23 is fixedly connected to the top of the second workbench 22. A servo driver 24 is fixedly connected to the bottom of the second workbench 22. The microcontroller 23 is electrically connected to the tension sensor 5. The microcontroller 23 is electrically connected to the servo driver 24. The servo driver 24 is electrically connected to the first motor 6. The servo driver 24 is electrically connected to the second motor 12. The servo driver 24 is electrically connected to the third motor 15.

[0027] The above structure, driven by the first motor 6, causes the lead screw 7 to rotate. A nut block 8 is threadedly connected to the middle of the lead screw 7, and the nut block 8 abuts against the fixed plate 2, causing the lead screw 7 to drive the nut block 8 to move up or down. An adjusting roller 9 is rotatably connected to the front of the nut block 8, and the lower part of the adjusting roller 9 abuts against the enameled wire. When the adjusting roller 9 moves downward, the tension of the enameled wire increases, and when the adjusting roller 9 moves upward, the tension of the enameled wire decreases.

[0028] By incorporating a tension sensor 5, the real-time tension of the enameled wire is sensed. The tension sensor 5 is electrically connected to a microcontroller 23, allowing it to transmit the sensed data to the microcontroller 23 via electrical signals. The microcontroller 23 is then electrically connected to a servo driver 24, enabling it to control the servo driver 24 through its programmed control. The servo driver 24 is electrically connected to a first motor 6, allowing the microcontroller 23 to drive the first motor 6 to rotate forward or backward. This achieves the adjustment of the rectangular enameled wire's tension based on its own tension, keeping the tension within a stable range.

[0029] A third roller 10 is rotatably connected to the upper right side of the first worktable 1. A mortise roller 11 is rotatably connected to the upper right side of the first worktable 1. A second motor 12 is fixedly connected to the middle rear of the fixed plate 2. A guide roller 13 is fixedly connected to the output end of the second motor 12. A support frame 14 is fixedly connected to the middle of the first worktable 1. The support frame 14 is rotatably connected to the guide roller 13. A stabilizing rod 21 is fixedly connected to the front right side of the fixed plate 2. The stabilizing rod 21 abuts against the collecting cylinder 18.

[0030] The above structure includes a second motor 12, with a guide roller 13 fixedly connected to the output end of the second motor 12. Driven by the second motor 12, the guide roller 13 rotates and comes into contact with the enameled wire, thus guiding the enameled wire to move back and forth. This allows the enameled wire to enter the collection cylinder 18 in a designated direction under the guidance of the guide roller 13.

[0031] By providing a second motor 12, which is electrically connected to a servo driver 24 and a microcontroller 23, the microcontroller 23 can control the servo driver 24 through its own program, thereby controlling the second motor 12. When the guide roller 13 guides the enameled wire from the rear end to the front end, the output end of the second motor 12 rotates in the opposite direction, causing the guide roller 13 to guide the enameled wire from the front end to the rear end again. This cycle is repeated to achieve better collection of the enameled wire.

[0032] The collection cylinder 18 is supported by a stabilizing rod 21, ensuring its stability during the collection of enameled wire. The locking nut 20 allows the operator to cut the enameled wire with a tool after collection, and remove the collection cylinder 18 by unscrewing the locking nut 20, thus completing the transfer of the collection cylinder 18.

[0033] By setting up a first motor 6, a second motor 12, and a third motor 15, all of which are servo motors, the servo driver 24 can control all three, that is, the output terminals of all three can rotate under the control of the microcontroller 23.

[0034] Working principle: This type of tension mechanism for rectangular enameled wire, when in use, first positions the rectangular enameled wire as follows... Figure 1The method shown is installed inside the device, and then the switches of the microcontroller 23 and the servo driver 24 are turned on. Under their control, the first motor 6, the second motor 12, and the third motor 15 are made to rotate forward, reverse, or increase or decrease speed in a specified manner. Through the action of the tension sensor 5, the microcontroller 23 can adjust the position of the adjusting roller 9 according to the real-time tension of the rectangular enameled wire, that is, adjust the tension of the rectangular enameled wire so that the tension of the rectangular enameled wire is within a range that can be stably collected. With the drive of the third motor 15, the collecting cylinder 18 completes the collection of the rectangular enameled wire.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
