Description

Technical Field

[0001] This utility model belongs to the technical field of nanocrystalline ribbon processing equipment, and in particular relates to an automatic winding device for nanocrystalline ribbon. Background Technology

[0002] Nanocrystalline ribbon is a type of iron-based soft magnetic alloy material prepared by rapid cooling technology. Its core technology lies in forming an amorphous precursor through ultra-rapid cooling, followed by precise heat treatment to control the precipitation of nanoscale grains, thus forming an amorphous / nanocrystalline dual-phase composite structure.

[0003] Currently, when winding nanocrystalline ribbons, the material roll needs to be loaded onto the unwinding station first, then enter the tension adjustment station to adjust the tension of the ribbon winding, and finally, after cutting, enter the rewinding station to complete the winding process. However, in the actual production process of the ribbon, existing winding equipment mainly uses simple mechanical adjustments such as dragging, electromagnetic adsorption, and counterweights to control the winding tightness. When the unwinding speed and winding speed are not matched, the tension is prone to sudden increase or slack, making it impossible to accurately control the winding tension. This results in large fluctuations in production quality, difficulty in ensuring product consistency, and an inability to meet the production requirements of high-precision nanocrystalline ribbons, leading to low efficiency.

When production is completed, the clamping component clamps the raw material, and the cutting component cuts the raw material.

[0025] Reference Appendix Figure 4 As shown, the tension control component 5 is set on the worktable 1, located between the unwinding component 2 and the winding component 3. The tension control component 5 is used to control the tension of the strip during the winding process, ensuring that the tension of the strip is kept within the set range, improving the transmission and winding stability of the strip, and avoiding problems such as strip breakage or wave formation. The tension control assembly 5 includes a motor support 51, vertically mounted on the worktable 1; a tension swing arm 52, mounted on the motor support 51 and located on the conveying path of the strip, which adjusts the tension of the strip by swinging to increase or decrease the length of the strip path; a tension adjusting motor 53, mounted on the motor support 51, connected to the middle of the tension swing arm 52 via a coupling 56, which drives the tension swing arm 52 to swing around the motor shaft of the tension adjusting motor 53 according to the instructions of the control assembly, thereby adjusting the tension of the strip; and two conveying rollers 54, respectively mounted at both ends of the tension swing arm 52, perpendicular to the tension swing arm 52, which support and convey the strip. The roller 54 has a low-friction bearing installed inside to reduce friction as the strip passes through from the bottom. Two energy storage units 55 are mounted on the worktable 1 at both ends of the tension swing arm 52. These units control the extreme positions of the tension swing arm 52 and absorb energy from impacts to prevent damage during equipment malfunctions. Specifically, the extreme positions of the tension swing arm 52 are controlled by the extension stroke of the energy storage units 55. A tension sensor 57 is mounted on the worktable 1 along the strip's transport path. It detects the strip tension in real time and feeds the tension signal back to the control components. A laser position sensor 58 is mounted on the worktable 1 and acquires the swing arm's position information by irradiating a laser receiving plate on the back of the tension swing arm 52.

[0026] Reference Appendix Figure 5As shown, the unloading assembly 6 includes a second linear module 61, mounted on the worktable 1; a slider 62, slidably mounted on the second linear module 61; a strip guide component 63, located at the first end of the slider 62, used to prevent the strip from loosening; the strip guide component 63 includes a baffle plate, which is pushed out during winding to prevent the strip from loosening; a flattening component 64, located at the second end of the slider 62 adjacent to the strip guide component 63, used to apply pressure to the surface of the core to eliminate wrinkles; an inner welding component 65, located at the third end of the slider 62 opposite to the strip guide component 63, used to weld the inner diameter weld points of the core; and an electromagnet unloading component 66, located at the side end of the inner welding component 65, used to attract the core for unloading. The unloading assembly 6 uses a second motor to drive the slider 62, moving each component mounted on the slider 62 along the second linear module 61 to the corresponding workstation, allowing for rapid positioning and arbitrary switching of forms according to different operating conditions. After winding, slider 62 moves the components mounted on it to the core position. The cylinder of flattening component 64 extends, and the flattening plate applies pressure to the core surface 2-3 times to eliminate wrinkles. The welding head of inner welding component 65 descends to weld the inner diameter weld points of the core. Electromagnetic unloading component 66 is energized to attract the core, and slider 62 moves along the second linear module 61 to move electromagnetic unloading component 66 above detection component 7, transferring the core above the detection component 7. Electromagnetic unloading component 66 is de-energized, and the core falls onto the weighing sensor, acquiring weight data. This utility model's unloading component 6 integrates flattening, welding, and unloading functions. By using the second linear module 61 and slider 62 to move each component to the corresponding station, it achieves rapid switching between corresponding functions, which is beneficial for improving production efficiency.

A discharge component is arranged in parallel with the weighing component. The discharge component is used to sort good and bad products. The welding assembly 8 of this invention is disposed on the workbench 1, above the winding assembly 3. The welding assembly 8 includes a welding circuit board and a welding floating component. The welding assembly 8 is used to perform outer diameter welding and inner diameter welding of the core before unloading after production is completed. In one embodiment, the welding floating component includes a spring, a rotating shaft, and a copper plate, and the copper plate is connected to the welding circuit board. The rotating shaft supports and connects the copper plate, providing angular floating so that the welding head reaches the designated position; the spring provides support and buffering; and the copper plate conducts current.

[0028] The control components of this invention are electrically connected to the unwinding assembly 2, the winding assembly 3, the feeding and cutting assembly 4, the tension control assembly 5, the unloading assembly 6, the detection assembly 7, and the welding assembly 8. Specifically, the control components are electrically connected to the unwinding motor 21, the winding motor, the tension adjusting motor 53, the tension sensor 57, the first cylinder 431, the outer diameter detection component, the weighing component, and the welding circuit board. The control components receive signals from the detection devices of each component and, based on set parameters and a PID control algorithm, control the operation of the unwinding motor 21, the winding motor, and the tension adjusting motor 53 to achieve high-precision control of the strip tension, thereby realizing automatic control of the strip winding process.

[0029] Reference Appendix Figure 6 The diagram shown is a flowchart of the tension control method for the automatic winding device for nanocrystalline ribbon of this invention. (See attached diagram.) Figure 7 The diagram shown illustrates the principle framework of the tension control method for the automatic nanocrystalline strip winding device of this invention. "-" indicates that the tension lever 52 swings clockwise, and "+" indicates that the tension lever 52 swings counterclockwise. The working principle of the tension control in the automatic nanocrystalline strip winding device of this invention is as follows: During operation, the strip passes over the conveyor roller 54. The tension sensor 57 detects the tension of the strip in real time and feeds the tension signal back to the control system. The control system compares the received tension signal value with the set value. When the detected tension signal value is greater than the set value, the control component drives the tension adjusting motor 53 to make the tension lever 52 swing counterclockwise to reduce the strip path length and lower the tension. When the detected tension signal value is less than the set value, the control component drives the tension adjusting motor 53 to make the tension lever 52 swing clockwise to increase the strip path length and increase the tension. Through the above adjustments, high-precision tension control is achieved, preventing strip breakage or wrinkling.

[0030] The working process of the tension control of the automatic winding device for nanocrystalline ribbon of this utility model is as follows: First, the equilibrium origin of the tension swing rod 52 is preset to 0°, and the swing range is +30° to -30°; when the automatic winding device for nanocrystalline ribbon is working, the PLC calculates the current position of the tension swing rod 52 and collects real-time position data by reading the position information of the tension swing rod 52 fed back by the laser position sensor 58; when the tension swing rod 52 is at the equilibrium origin, no adjustment is required; when the tension swing rod 52 deviates from the equilibrium origin, the PLC calculates the current position of the tension swing rod 52 and collects real-time position data by comparing the preset position of the tension swing rod 52 with the tension swing rod data received by the PLC. The actual position data of 52 is used to calculate the required compensation speed value of the tension swing arm 52, and this compensation speed value is fed back to the PLC. The PLC controls the tension regulating motor 53, which in turn controls the swing position of the tension swing arm 52 for real-time compensation. When the tension decreases, the tension swing arm 52 is pulled to the left, and conversely, when the tension increases, the tension swing arm 52 moves to the right. At this time, the encoder connected to the tension swing arm 52 can reflect the change in the tension of the strip. The real-time roll diameter is calculated using proportional calculation or PID estimation, and then PID calculation is performed to add compensation calculation to realize the control method. 1. Proportional calculation method: , , In the formula, m This indicates the pulse that represents one revolution of the feed roller; d Indicates the diameter of the feed roller; ∑ m This indicates the pulse count value of the feed roller; 2. PID estimation method: When it is in a small range of stable change ; In the formula, MV This indicates the current PID output of the control axis; SQRT Indicates the speed setting; When the equipment is undergoing rapid and widespread changes, or just starting up... ; When in a stable state ; 3. The PID value is calculated using the following formula: , In the formula, e(t) This represents the difference between the set tension and the feedback tension; u( t () indicates the amount of computation to be output; K p Indicates the scaling factor; T i Indicates the integration time constant; Td Represents the differential time constant; 4. The speed compensation value should be calculated using the following formula: , In the formula, W represents the speed compensation value of the tension regulating motor; v represents the speed of the tension regulating motor; u( t ) represents the output computation of the PID value; D represents the shaft diameter of the tension lever.
