Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a split-type yarn angle sensor. Background Technology

[0002] In the field of yarn winding counting or yarn separating equipment, angle sensors are a core component used to ensure the quality of yarn forming. An existing yarn angle sensor (publication number: CN222951686U) has been disclosed. Although it can achieve basic angle detection and solve the problem of yarn tangling during the yarn winding process, it still has obvious defects in actual use and cannot meet the needs of long-term stable production: First, the sensor is an integrated structure, and its internal rotating component and sensor housing need to be tightly fitted together to realize the angle rotation and detection functions. However, during long-term operation, the mating surface between the rotating component and the housing will generate mechanical friction due to wear and dust accumulation. When the frictional resistance increases, it will cause the equipment to stall, and a "clicking" noise will be emitted during the frictional contact, which will seriously affect the smoothness of the equipment operation. Second, the above-mentioned mechanical friction and operational stalling will directly interfere with the angle signal acquisition accuracy of the internal detection element of the sensor, causing the detection element to be unable to accurately and stably capture the angle change of the rotating component. This will cause irregular fluctuations in the electrical signal output by the sensor, resulting in yarn winding count deviation and inaccurate tension control after the signal is transmitted to the equipment controller. Ultimately, this will result in uneven yarn side forming and segmented defects, affecting product quality. Summary of the Invention

[0003] In view of the above shortcomings, this utility model provides a one-piece yarn angle sensor that can effectively eliminate jamming and abnormal noise while achieving stable signal output and ensuring yarn forming quality.

[0004] To achieve the above objectives, this utility model employs a split-type yarn angle sensor, comprising a sensor body, which includes a moving component and a sensing component. The sensing component contains a circuit board and an angle magnetic detection chip disposed on the circuit board. The moving component includes a connection end for connecting to a motor and a magnet extending to one side of the angle magnetic detection chip. The magnet is connected to the motor through the connection end and rotates synchronously with the motor in both forward and reverse directions, continuously remaining within the detectable range of the angle magnetic detection chip. Sensing signal output is achieved through magnetic field induction between the magnet and the angle magnetic detection chip.

[0005] The present invention is further configured such that the magnet and the angle magnetic detection chip are arranged in an intermittent manner.

[0006] The present invention is further configured such that the sensor body also includes a mounting base connected to the motor, the sensing component is limited to the mounting base, and the angle magnetic detection chip is configured to correspond to the magnet in a non-contact manner.

[0007] The present invention is further configured such that the sensing component includes a receiving cavity, a circuit board, and an angle magnetic detection chip disposed on the circuit board. The angle magnetic detection chip is disposed in the sensing component through the receiving cavity. The angle magnetic detection chip is distributed in a direction away from the bottom of the receiving cavity. The circuit board and the angle magnetic detection chip are encapsulated by potting to form a potting limit for the circuit board and the angle magnetic detection chip in the sensing component. The magnet is distributed on the side near the opening of the receiving cavity.

[0008] The present invention is further configured such that the angle magnetic detection chip is a 0-5V analog output chip or a 12-bit digital output chip.

[0009] The present invention is further configured such that the mounting base includes a cutout on the mounting base, a locking cavity arranged on the side of the cutout, and a mounting part for fixing the mounting base. The sensing component also includes a sensing body and a locking part distributed on the side of the sensing body and adapted to the locking cavity. The receiving cavity in the sensing component is distributed in the sensing body. The sensing component passes through the sensing body and is inserted into the cutout. The locking part and the locking cavity cooperate to form a mounting limit for the sensing component on the mounting base.

[0010] The present invention is further configured such that the moving part is a bracket with a magnet, the connecting end is at least two fixed parts that extend toward and are connected to the motor, and the magnet is confined on the side end of the fixed part that extends away from the end connected to the motor and extends to the side of the motor shaft.

[0011] The present invention is further configured such that the distance between the angle magnetic detection chip and the magnet is 1-2mm.

[0012] The present invention is further configured such that the number of locking cavities is two or more, and the number of locking parts is adapted to the number of locking cavities.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By adopting a split structure design for the moving parts and sensing parts of the main body of the angle sensor applicable in the field of yarn winding counting or yarn separating equipment, the moving parts and sensing parts can be independently assembled, disassembled and maintained without the need to disassemble the entire sensor. This significantly reduces the assembly difficulty and subsequent maintenance cost of the angle sensor, and also makes it suitable for the mass production and maintenance needs of textile equipment. At the same time, the angle sensor involved in this utility model can completely abandon the tight snap-fit ​​assembly method of traditional integrated sensors, thereby eliminating the problems of operation jamming and abnormal noise caused by mechanical friction between the rotating components and the housing in existing sensors, thus ensuring the smooth operation of the equipment.

Detailed Implementation

[0015] like Figure 1-10As shown, a specific embodiment of this utility model is a split-type yarn angle sensor, including a sensor body, which includes a moving part 3 and a sensing part 2. The sensing part 2 has a circuit board 24 inside, and an angle magnetic detection chip 23 arranged on the circuit board 24. The moving part 3 includes a connection end 31 for connecting to a motor, and a magnet 32 ​​extending to one side of the angle magnetic detection chip 23. The magnet 32 ​​is connected to the motor through the connection end 31. The magnet 32 ​​rotates synchronously with the forward and reverse rotation of the motor and is continuously within the detectable range of the angle magnetic detection chip 23. The sensing signal is output through the magnetic field induction between the magnet 32 ​​and the angle magnetic detection chip 23.

[0016] By adopting a split structure design for the moving part 3 and the sensing part 2 of the main body of the angle sensor used in yarn winding counting or yarn separating equipment, the moving part 3 and the sensing part 2 can be independently assembled, disassembled and maintained without disassembling the entire sensor. This significantly reduces the assembly difficulty and subsequent maintenance cost of the angle sensor, and also makes it suitable for the mass production and maintenance needs of textile equipment. At the same time, the angle sensor involved in this utility model can completely abandon the tight snap-fit ​​assembly method of traditional integrated sensors, thereby eliminating the problems of operation jamming and abnormal noise caused by mechanical friction between the rotating components and the housing in existing sensors, thus ensuring the smooth operation of the equipment. The preferred solution for the magnet 32 ​​is a permanent magnet 32.

[0017] like Figure 1-10 As shown, the magnet 32 ​​and the angle magnetic detection chip 23 are arranged in an intermittent manner, which makes the angle sensor involved in this utility model adopt a non-contact intermittent sensing design between the magnet 32 ​​and the angle magnetic detection chip 23. This avoids the interference of friction on the detection accuracy, and enables the angle magnetic detection chip 23 to accurately capture the angle change of the magnet 32 ​​and output a stable electrical signal. This effectively solves the defects of existing sensors, such as yarn winding counting deviation and inaccurate tension control caused by signal fluctuation, and improves the yarn forming quality. The preferred interval distance of 1-2mm can balance magnetic field sensing sensitivity and assembly convenience, preventing assembly interference caused by too small a spacing and avoiding the problem of magnetic field signal weakening caused by too large a spacing.

[0018] like Figure 1-4As shown in Figure 7, the sensor body also includes a mounting base 1 connected to the motor. The sensing component 2 is positioned on the mounting base 1, and the angle magnetic detection chip 23 and the magnet 32 ​​are arranged in a non-contact correspondence. The core function of the mounting base 1 is to serve as the connection carrier between the sensor body and the motor, as well as the precise positioning reference for the sensing component 2. The mounting base 1 is directly connected to the end face of the motor, providing a unified mounting reference for the separately designed moving component 3 and sensing component 2, so that the sensor is stably mounted on the motor, avoiding displacement or shaking during equipment operation; at the same time, through the mounting base 1 The structural constraints precisely limit the position of the sensing component 2, ensuring that the angle magnetic detection chip 23 inside the sensing component 2 and the magnet 32 ​​on the moving component 3 always maintain a coaxial and non-contact correspondence, providing structural support for the stability of magnetic field sensing. The moving component 3 is an L-shaped bracket structure, with one end fixed to the motor shaft and the other end carrying the magnet 32. When the motor shaft drives the L-shaped bracket to rotate around the axis, the magnet 32 ​​swings synchronously with the bracket and is always within the effective sensing range of the angle magnetic detection chip 23. Finally, the angle signal is acquired through the change of magnetic field.

[0019] like Figure 9-10 As shown, the sensing component 2 includes a cavity 25, a circuit board 24, and an angle magnetic detection chip 23 disposed on the circuit board 24. The angle magnetic detection chip 23 is disposed within the sensing component 2 through the cavity 25. The angle magnetic detection chip 23 is distributed in a direction away from the bottom of the cavity 25 and is encapsulated with potting compound to form a potting limit for the circuit board 24 and the angle magnetic detection chip 23 within the sensing component 2. The design of the magnet 32 ​​being distributed on one side near the opening of the cavity 25 allows the circuit board 24 and the angle magnetic detection chip 23 within the sensing component 2 to be limited by the potting compound. This not only provides a firm fixation but also achieves dustproof, waterproof, and vibration-resistant effects, avoiding interference and damage to the chip from textile workshop fly hair, dust, and equipment vibration, and extending the service life of the sensor.

[0020] like Figure 9-10 As shown, the angle magnetic detection chip 23 is designed as a 0-5V analog output chip or a 12-bit digital output chip, which enables the angle magnetic detection chip 23 involved in the angle sensor to support both 0-5V analog and 12-bit digital output modes. This also makes the angle sensor involved in this utility model adaptable to different types of textile equipment control systems, thus improving the versatility of the sensor.

[0021] like Figure 1-9As shown, the mounting base 1 includes a cutout 13, a locking cavity 11 located on the side of the cutout 13, and a mounting part 12 for fixing the mounting base 1. The sensing component 2 also includes a sensing body 21 and locking parts 22 located on the side of the sensing body 21 and adapted to the locking cavity 11. The receiving cavity 25 in the sensing component 2 is located in the sensing body 21. The sensing component 2 passes through the sensing body 21 and is inserted into the cutout 13. The locking part 22 and the locking cavity 11 cooperate to form a design scheme for limiting the installation of the sensing component 2 on the mounting base 1. This allows the mounting base 1 to quickly limit the installation of the sensing component 2 through the cooperation structure between the cutout 13 and the locking cavity 11, without the need for additional fasteners, thus improving assembly efficiency.

[0022] like Figure 2-6 As shown, the moving part 3 is a bracket with a magnet 32. The connecting end 31 consists of at least two fixed parts that extend toward and connect to the motor. The magnet 32 ​​is limited to the side end of the fixed part that extends away from the end connected to the motor and extends to the side of the motor shaft. This design can ensure the stability of the connection between the magnet 32 ​​and the motor and prevent the moving part 3 from shaking or shifting during the rotation of the motor.

[0023] like Figure 1-2 As shown in Figures 4 and 7, the number of locking cavities 11 is two or more, and the number of locking parts 22 is matched with the number of locking cavities 11. This scheme can ensure the coaxiality of the sensor component 2 during installation and ensure the alignment accuracy of the magnet 32 ​​and the angle magnetic detection chip 23.
