Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a device for automatically measuring magnesium rods in a winding machine. Background Technology

[0002] During winding operations on a winding machine, the outer diameter of the mandrel (such as a magnesium rod) is a crucial factor in adjusting parameters such as the outer diameter and number of turns of the winding wire (such as a heating wire). In existing technology, before mandrel assembly, the outer diameter is typically measured manually using calipers. The measured data is then manually input into the winding machine's control panel. The winding machine then generates matching winding parameters based on the input data, thereby driving the equipment to complete the winding operation. This process relies on manual operation and is currently a common practice in the industry.

[0003] However, manual measurement and data input require specialized training for employees to master the use of measuring tools, data reading, and input operations, which to some extent affects production efficiency. Furthermore, errors in measurement, reading, and input are inevitable during manual operation. These errors directly affect the fit between the winding and the mandrel, thereby reducing product yield and causing unnecessary production problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for automatically measuring magnesium rods in a winding machine. This device automatically measures the outer diameter of the magnesium rod and automatically inputs the data into the winding machine control system to generate matching winding parameters. It reduces manual measurement and input errors, improves the level of winding automation and production efficiency, and solves the problem that existing winding machines require manual measurement of the mandrel's outer diameter and manual input of parameters, which affects production efficiency and makes it easy for operational errors to affect product yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for automatically measuring magnesium rods on a winding machine, comprising a base frame, a control mechanism mounted on one side of the base frame, an electric clamping rotator mounted on the control mechanism, and a magnesium rod body clamped on the electric clamping rotator.

[0006] The base frame on the opposite side of the electric clamping rotator is provided with a positioning mechanism, which works with the electric clamping rotator to position the magnesium rod body.

[0007] The control mechanism is equipped with a light receiver and an optical measurement module, and the optical measurement module and the light receiver are arranged opposite to each other to form a detection optical path.

[0008] Preferably, a vertical plate is fixed on the base frame, and a first guide mechanism and a second guide mechanism are installed on the base frame on one side of the vertical plate.

[0009] In the design, the upright plate fixed on the base frame and the first and second guide mechanisms installed on the base frame on one side of the upright plate provide support and guidance for the positioning mechanism and the winding mechanism. This structure has a stable installation foundation, which can ensure that each component maintains a precise relative position during operation. The separate guide design can meet the movement requirements of positioning and winding respectively.

[0010] Preferably, the first guiding mechanism includes a first lead screw and a guide slide rod, and the positioning mechanism is threadedly connected to the first lead screw and slidably engaged with the guide slide rod.

[0011] In the design, the first guide mechanism, including the first lead screw and guide slide, forms a threaded connection and sliding fit with the positioning mechanism, which enables the smooth movement of the positioning mechanism. This structure has precise position adjustment capability and can adapt to the positioning requirements of magnesium rods of different lengths. The use of lead screw drive and slide guide can ensure the straightness and stability of the positioning mechanism during movement.

[0012] Preferably, the second guide mechanism includes a second lead screw, on which a winding mechanism is threadedly connected.

[0013] In the design, the second guide mechanism includes a second lead screw, which is threadedly connected to the winding mechanism to enable the winding mechanism to move along the axial direction of the magnesium rod body. This structure has a reliable driving effect and can ensure that the wire is wound evenly during the winding process. The lead screw transmission method can achieve precise control of the moving speed and position of the winding mechanism.

[0014] Preferably, the winding mechanism is equipped with a wire feeder, and the wire feeder is provided with a wire release roller for placing the wire to be wound.

[0015] In the design, the wire feeding frame and the wire feeding roller installed on the winding mechanism realize the placement and transportation of the wire to be wound. This structure has a convenient wire supply function and can continuously provide wire for the winding operation. The combination of the wire feeding frame and the wire feeding roller can ensure the smoothness of the wire transportation process.

[0016] Preferably, the light receiver is fixed to the control mechanism by a first mounting bracket and electrically connected to the control mechanism by a first connecting line.

[0017] In the design, the light receiver is fixed to the control mechanism by the first mounting bracket and electrically connected to the control mechanism through the first connecting line to realize the reception and transmission of the detection light signal. This structure has a stable signal transmission capability and can accurately transmit the light signal to the control mechanism for processing. The fixed installation and wired connection method can ensure the stability and timeliness of signal transmission.

[0018] Preferably, the optical measurement module is fixed to the control mechanism by the first support frame, and the installation positions of the optical measurement module and the light receiver correspond radially to the magnesium rod body.

[0019] In the design, the optical measurement module is fixed to the control mechanism by the first support frame, and its installation position with the light receiver corresponds to the radial direction of the magnesium rod body, realizing the accurate detection of the outer diameter of the magnesium rod body. This structure has a reliable detection function, can form an effective detection optical path to obtain accurate obstruction light signals, and the installation method corresponding to the radial direction of the magnesium rod body can ensure the accuracy of the measurement data.

The light receiver transmits the received light signal to the control mechanism, which automatically processes the data and generates matching winding parameters. This eliminates the need for manual measurement and input, thereby reducing human error, improving the level of winding automation, and increasing production efficiency. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] Example 1

[0029] like Figure 1 and Figure 2 As shown, a device for automatically measuring mandrels in a winding machine includes a base frame 1. A vertical plate 11 is bolted to the base frame 1, and the vertical plate 11 is perpendicular to the surface of the base frame 1 and rigidly connected to the base frame 1. A control mechanism 2 is mounted on one side of the base frame 1 by screws. The control mechanism 2 has a built-in PLC controller and drive module, and its outer surface is provided with an electric clamping rotator 21. The electric clamping rotator 21 includes a drive motor and arc-shaped grippers. The inner side of the grippers is provided with a rubber anti-slip layer for stabilizing the mandrel body 7 and driving the mandrel body 7 to rotate around its own axis under the drive of the drive motor.

[0030] A first guide mechanism 3 and a second guide mechanism 4 are provided on the base frame 1 along the axial direction of the mandrel body 7. The first guide mechanism 3 includes a first lead screw 31 and a guide slide rod 32. The two ends of the first lead screw 31 are rotatably connected to the base frame 1 through bearing seats, and one end of the first lead screw 31 is connected to a servo motor. The guide slide rod 32 is parallel to the first lead screw 31 and its two ends are fixed to the base frame 1. The second guide mechanism 4 includes a second lead screw 41. The installation method of the second lead screw 41 is the same as that of the first lead screw 31, and its servo motor is electrically connected to the drive module in the control mechanism 2. The winding mechanism 6 is installed on the second guide mechanism 4. The bottom of the wire feeding frame 61 of the winding mechanism 6 is provided with a nut seat that matches the second lead screw 41 and a sliding sleeve that matches the guide slide rod 32. The wire feeding frame 61 is rotatably connected to the wire feeding roller 62 through a rotating shaft. The wire feeding roller 62 is provided with baffles at both ends to limit the axial displacement of the wire to be wound and to achieve stable placement of the wire to be wound.

[0031] The base frame 1 is also equipped with a positioning mechanism 5, which includes a positioning seat and a nut block connected to the positioning seat. The nut block is threadedly connected to the first lead screw 31. The bottom of the positioning seat is provided with a through hole that slides with the guide slide rod 32. The side of the positioning seat facing the electric clamping rotator 21 is provided with a V-groove, in which wear-resistant ceramic plates are embedded. The plates are arranged opposite to the jaws of the electric clamping rotator 21, forming a two-point positioning for the mandrel body 7, ensuring that the axis of the mandrel body 7 remains parallel to the first lead screw 31 and the second lead screw 41. A light receiver 8 is fixed on the control mechanism 2 by a first mounting bracket 81. The first mounting bracket 81 is connected to the housing of the control mechanism 2 by welding. The receiving surface of the light receiver 8 is radially perpendicular to the mandrel body 7, and it is electrically connected to the PLC controller inside the control mechanism 2 through a first connecting line 82. An optical measurement module 9 is fixed to the control mechanism 2 via a first support frame. The first support frame is connected to the control mechanism 2 by bolts. The optical measurement module 9 has a built-in laser emitter, and its emitting end is directly opposite the receiving end of the light receiver 8. The formed detection optical path passes through the radial outer side of the core rod body 7. The laser wavelength is 650nm and the spot diameter is 0.5mm to ensure detection accuracy.

[0032] During operation, after the mandrel body 7 is fixed by the grippers of the electric clamping rotator 21 and the V-groove of the positioning mechanism 5, the control mechanism 2 controls the optical measurement module 9 to emit a laser. The light receiver 8 receives the laser signal after it is blocked by the mandrel body 7 and transmits the signal to the PLC controller through the first connecting line 82. The PLC controller calculates the outer diameter of the mandrel body 7 according to the preset conversion formula and automatically generates parameters such as the number of winding coils and the wire spacing. Subsequently, the control mechanism 2 drives the servo motor of the second lead screw 41 to rotate, which drives the wire feeder 61 to move at a constant speed along the guide slide bar 32. The wire on the pay-off roller 62 is led out through the wire threading hole 22 and evenly wound around the rotating mandrel body 7 under the guidance of the guide wheel of the winding mechanism 6.

[0033] Specifically, by setting up a base frame 1, a control mechanism 2, an electric clamping rotator 21, a magnesium rod body 7, a positioning mechanism 5, a light receiver 8, and an optical measurement module 9, after the magnesium rod body 7 is positioned by the electric clamping rotator 21 and the positioning mechanism 5, the detection optical path formed by the optical measurement module 9 and the light receiver 8 can automatically measure the outer diameter of the magnesium rod body 7. The light receiver 8 transmits the received light signal to the control mechanism 2, and the control mechanism 2 automatically processes the data and generates matching winding parameters. No manual measurement and input are required, which reduces manual operation errors, improves the level of winding automation, and increases production efficiency.

[0034] Example 2

[0035] like Figure 3 and Figure 4As shown, a device for automatically measuring mandrels in a winding machine includes a base frame 1. A vertical plate 11 is fixed to the base frame 1 by bolts. The surface of the vertical plate 11 is precision machined to ensure flatness. A control mechanism 2 is mounted on one side of the base frame 1 by screws. The control mechanism 2 has a built-in PLC controller with data storage function. Its outer surface is provided with an electric clamping rotator 21 and a wire-passing hole 22. The structure of the electric clamping rotator 21 is the same as in Embodiment 1. It is used to clamp the mandrel body 7 and drive it to rotate. The inner wall of the wire-passing hole 22 is inlaid with a polytetrafluoroethylene sleeve to reduce wear when the wire passes through and to allow the wire to pass through smoothly.

[0036] The base frame 1 is provided with a first guide mechanism 3 and a second guide mechanism 4 along the axial direction of the core rod body 7. The first guide mechanism 3 includes a first lead screw 31 and a guide slide 32, and its structure is the same as in Embodiment 1. The second guide mechanism 4 includes a second lead screw 41, and the thread precision of the second lead screw 41 is C3 grade to ensure the smooth movement of the wire feeder 61. The winding mechanism 6 is mounted on the second guide mechanism 4. The wire feeder 61 of the winding mechanism 6 is threadedly connected to the second lead screw 41. A pay-off roller 62 is rotatably connected to the wire feeder 61 through a bearing. The structure of the pay-off roller 62 is the same as in Embodiment 1.

[0037] A positioning mechanism 5 is provided on the base frame 1. The structure of the positioning mechanism 5 is the same as that in Embodiment 1. It works in conjunction with the electric clamping rotator 21 to position the core rod body 7, ensuring that the axis of the core rod body 7 is parallel to the moving direction of the wire feeder 61. A second mounting bracket 83 is welded to the wire feeder 61. The second mounting bracket 83 is an L-shaped steel plate. One end of the second mounting bracket 83 is connected to the wire feeder 61, and the other end is bolted to a light receiver 8. The receiving surface of the light receiver 8 is radially perpendicular to the core rod body 7. A crossbar 84 is mounted on one side of the light receiver 8 with screws. The crossbar 84 is a stainless steel round rod. After passing through the wire hole 22, it is welded to the internal connecting frame of the control mechanism 2. The surface of the crossbar 84 is smooth to reduce wear on the second connecting wire 85. The light receiver 8 is electrically connected to the PLC controller in the control mechanism 2 through the second connecting wire 85. The second connecting wire 85 is spirally wound on the crossbar 84 with a spiral pitch of 5cm to ensure that the connecting wire can freely extend and retract when the wire feeder 61 moves, avoiding pulling or tangling. An optical measurement module 9 is fixed on the base frame 1 by a second support frame 91. The second support frame 91 is bolted to the base frame 1. The structure of the optical measurement module 9 is the same as that in Embodiment 1. Its emitting end and the receiving end of the light receiver 8 are always aligned to form a stable detection optical path.

[0038] During operation, after the mandrel body 7 is fixed by the positioning mechanism 5 and the electric clamping rotator 21, the control mechanism 2 drives the servo motor of the second lead screw 41 to operate. The wire feeder 61 moves smoothly along the guide slide bar 32, and the light receiver 8 moves synchronously with the wire feeder 61. During the movement, the crossbar 84 supports the second connecting wire 85, and the spirally wound connecting wire freely extends or contracts with the movement. The optical measurement module 9 emits a laser, and the light receiver 8 receives the light signal in real time and transmits it to the control mechanism 2 through the second connecting wire 85. The PLC controller calculates the outer diameter of the mandrel body 7 based on the initial light signal and generates initial winding parameters. On the other hand, during the winding process, the moving light receiver 8 captures the contour signal of the wound wire, calculates parameters such as the coil distance, and compares them with preset values. If there is a deviation, the rotation speed of the second lead screw 41 is adjusted in real time to achieve dynamic correction of the coil distance. The wire on the pay-off roller 62 is wound around the mandrel body 7 under the drive of the wire feeder 61. At the same time, the real-time detection of the winding process by the light receiver 8 ensures the stability of the winding quality.

[0039] This embodiment, through synchronous movement design, retains the advantages of the first embodiment in automatically measuring the outer diameter of the mandrel, and adds a dynamic quality detection function during the winding process, further improving product consistency and yield.
