Description

Technical Field

[0001] This utility model belongs to the field of high-voltage coil production equipment, specifically relating to an automatic correction mechanism for flat coil production. Background Technology

[0002] In the production of flat coils, although traditional winding equipment is equipped with a wire-laying device, the raw material coil is not always discharged from the center of the coil. Instead, it swings left and right, causing the angle between the discharged raw material coil and the wire-laying frame to continuously change. This angular fluctuation causes the raw material coil to deviate from its conveying path when it is transported to the wire-laying device, resulting in a decrease in wire-laying accuracy. This leads to quality problems such as uneven number of turns and wire misalignment in the wound flat coils. In severe cases, it can even cause the raw material coil to jam or break, affecting production efficiency. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] This invention aims to solve the problem that the wire laying device equipped with traditional winding equipment causes the angle between the raw material wire outlet and the wire laying frame to change continuously. This angle fluctuation causes the raw material wire to deviate from the conveying path when it is conveyed to the wire laying device, resulting in a decrease in wire laying accuracy.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Please see Figures 1-6 The diagram shows an automatic correction mechanism for flat coil production. The mechanism includes a mounting plate 1, horizontal plates 2 arranged symmetrically on the top and bottom, and vertical plates 3 arranged vertically. One end of the two horizontal plates 2 is rigidly connected to the mounting plate 1 by welding or high-strength bolts to ensure connection stability. The other end is also fixed to the side of the vertical plate 3 by a rigid connection, forming the basic frame of the mechanism.

[0029] Two horizontal guide rollers 4 are arranged parallel to each other between the upright plate 3 and the mounting plate 1. The horizontal guide rollers 4 are used to guide and limit the raw material line in the horizontal direction. Two vertical guide rollers 5 are arranged parallel to each other between the two horizontal plates 2. The vertical guide rollers 5 are used to guide and limit the raw material line in the vertical direction. The horizontal guide rollers 4 and the vertical guide rollers 5 work together to achieve the initial limit of the conveying direction of the raw material line, and at the same time help stabilize the discharge posture of the raw material line.

[0030] A fixed plate 6 is rigidly connected to one side of the upper horizontal plate 2 by bolts. The fixed plate 6 has a rectangular plate structure. A fixed seat 7 is fixed to the upper part of the fixed plate 6 by screws. A set of conductive plastic angular displacement sensors 8 are installed on the fixed seat 7. The conductive plastic angular displacement sensors 8 are used to detect the angle change between the material output of the raw material line and the wire rack in real time. The follower shaft of each conductive plastic angular displacement sensor 8 passes through the fixed seat 7 and is connected to a connecting shaft 9 by a Phillips head coupling. The Phillips head coupling can effectively compensate for the radial and axial deviations between the two shafts and ensure the accuracy of the angle signal transmission. A guide plate 10 is fixedly connected to the lower end of each connecting shaft 9 by welding or keying. The outer circumference of the connecting shaft 9 is connected to the fixed plate 6 by a deep groove ball bearing, so that the connecting shaft 9 can rotate flexibly around its own axis to ensure the sensitivity of angle detection. A material stop roller 11 is also rotatably installed at the lower part of the guide plate 10 away from the fixed plate 6 by a pin. The material stop roller 11 is a component that contacts the surface of the raw material line. The rolling contact reduces the wear on the surface of the raw material line and avoids the raw material line jamming.

[0031] A tension spring post 13 is welded to the upper part of the guide plate 10 near the fixed plate 6, and a tension spring post 24 is welded to the upper end face of the fixed plate 6. The two tension spring posts 13 are connected to the tension spring post 24 through a tension spring 12. The tension spring 12 is always in a stretched state to provide a restoring force for the guide plate 10, ensuring that the guide plate 10 can drive the stop roller 11 to return to the correct position in time when the raw material line angle is restored, and ensuring the stability of the detection benchmark.

[0032] Both tension spring post 13 and tension spring post 2 14 are provided with an annular groove 15 at their upper parts. The annular groove 15 can prevent the tension spring 12 from falling off the tension spring post during the stretching or reset process, and facilitates stable connection of the tension spring 12.

[0033] A protective cover 20 is also fixed to the fixed plate 6 by bolts. The protective cover 20 covers the tension spring column 13, tension spring column 24, tension spring 12 and conductive plastic angular displacement sensor 8 to prevent external dust and impurities from entering and affecting the angle detection accuracy, and at the same time prevents personnel from accidentally touching it.

[0034] Both the upright plate 3 and the mounting plate 1 are provided with a vertical waist-shaped through hole 16 and a handle bolt 17. The handle bolt 17 passes through the waist-shaped through hole 16 and is connected to both ends of a transverse guide roller 4 near one end of the conductive plastic angular displacement sensor 8. By loosening the handle bolt 17, the position of the transverse guide roller 4 can be adjusted along the vertical direction of the waist-shaped through hole 16 to adapt to the transverse limiting requirements of raw material lines of different diameters.

[0035] Two horizontal plates 2 are provided with a waist-shaped through hole 2 18 and a handle bolt 2 19 at the end away from the mounting plate 1. The handle bolt 2 19 passes through the waist-shaped through hole 2 18 and is connected to both ends of the vertical guide roller 5 on the side away from the mounting plate 1. By loosening the handle bolt 2 19, the position of the vertical guide roller 5 can be adjusted in the horizontal direction along the waist-shaped through hole 2 18 to adapt to the vertical limiting requirements of raw material lines of different diameters.

[0036] Working principle:

[0037] In the flat coil winding production process, this mechanism is installed between the raw material coil and the wire laying frame. The mechanism is connected to the wire laying frame via a mounting plate 1. The raw material wire passes sequentially through the guide channel formed by the stop roller 11 at the bottom of the guide plate 10, two horizontal guide rollers 4, and two vertical guide rollers 5. The guide plate 10 does not directly contact the raw material wire. At this time, the conductive plastic angular displacement sensor 8 is in its initial detection state, recording the reference angle between the raw material wire and the wire laying frame. When the raw material wire shifts left or right due to the oscillation of the raw material coil output, the raw material wire only pushes the stop roller 11. The stop roller 11 rotates around the pin shaft and drives the guide plate 10 to oscillate synchronously around the axis of the connecting shaft 9. The connecting shaft 9 drives the follower shaft of the conductive plastic angular displacement sensor 8 to rotate through a plum blossom coupling. The conductive plastic angular displacement sensor 8 converts the "angle change between the raw material wire output and the wire laying frame" into an electrical signal and realizes... The angle signal is transmitted to the external control device. After receiving the angle signal, the external control device controls the wire guide frame to adjust its position or running speed according to the preset compensation algorithm to offset the deviation caused by the angle fluctuation of the raw material line and realize wire guide compensation. When the swing amplitude of the raw material line decreases and the angle returns to the reference range, the reset force of the tension spring 12 pulls the tension spring column 13, which drives the guide plate 10, the stop roller 11, the connecting shaft 9, and the follower shaft of the conductive plastic angular displacement sensor 8 to return to the initial position, waiting for the next angle detection and compensation. At the same time, according to the diameter specification of the raw material line, the distance between the horizontal guide roller 4 and the vertical guide roller 5 can be adjusted by adjusting the position of the handle bolt 17 in the waist-shaped through hole 16 and the position of the handle bolt 19 in the waist-shaped through hole 18 to ensure stable conveying of the raw material line and not affect the contact state between the stop roller 11 and the raw material line and the angle detection accuracy.
