Description

Technical Field

[0001] The present application relates to the technical field of displacement signal detection equipment, and in particular to a touch-type displacement signal device and a signal sending method. Background Art

[0002] In modern industrial automation systems, accurate displacement signal transmission is particularly important for mobile devices running along tracks. Position feedback, especially at critical stopping positions or acceleration and deceleration positions, is one of the key technologies to ensure the safe and efficient operation of mobile devices.

[0003] At present, in order to achieve precise positioning and signal transmission of mobile devices at key positions, traditional displacement signal detection methods mainly rely on photoelectric sensors and magnetic switches. When using photoelectric sensors for position detection, several gratings or reflectors are set on the track. When the mobile device passes through these positions, the sensor will detect the change in light and trigger the corresponding signal. When using magnetic switches for position detection, magnets are installed at key positions of the track, and the mobile device is equipped with a magnetic sensitive element. When the two are close, a change in the magnetic field will be generated, thereby triggering a signal.

[0004] However, traditional photoelectric sensors and magnetic switches can be affected by environmental factors (such as dust and electromagnetic interference), leading to misjudgments or failures. This often results in the mobile device failing to generate or transmitting a displacement signal in a timely manner after reaching the desired position, causing problems in subsequent control processes. Therefore, improving the reliability and accuracy of displacement signal detection has become a pressing technical challenge. Summary of the Invention

[0033] The following will be combined with the Figure 1 -Attached Figure 7 The technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention and do not constitute a complete set of implementations. Those skilled in the art can combine the embodiments of the present invention to derive other embodiments without inventive work, and such embodiments are also within the scope of protection of the present invention.

[0034] The inventors of this application have discovered that traditional displacement signal detection methods primarily rely on photoelectric sensors and magnetic switches, which can be susceptible to misjudgment or failure due to environmental factors (such as dust and electromagnetic interference). This often results in the mobile device failing to generate or timely generate a displacement signal after reaching a corresponding position, leading to problems with subsequent control processes. Therefore, this application discloses a touch-type displacement signal device and signal transmission method, primarily employing the following scheme:

[0035] The embodiment of the present application discloses a touch-type displacement signal device. Figure 1, comprising a guide rail 1 and a moving frame 2. The moving frame 2 is slidably mounted on the guide rail 1 along the length of the guide rail 1. A plurality of contacts 3 are mounted on the guide rail 1 along the length of the guide rail 1. Contacts 4 are mounted on the moving frame 2, and the contacts 4 are used to contact the contacts 3 on the guide rail 1. During use, the guide rail 1 is mounted on the path of the moving device, and the contacts 3 are mounted at the key stopping positions or acceleration and deceleration positions of the moving device. The moving frame 2 is fixed to the moving device, so that the moving device drives the moving frame 2 to move along the length of the guide rail 1.

[0036] Reference Figure 1 、 2 , each contact 3 is equipped with a signal transmission unit 31, which is used to convert the physical signal generated by the contact 4 and the contact 3 into an electrical signal. The signal transmission units 31 of each contact 3 are electrically connected to an integrated control system 32, and the integrated control system 32 is electrically connected to a prompt device 33. The signal transmission unit 31 can be a small circuit board with a built-in microprocessor and a signal amplifier. When the contact 4 contacts the contact 3, a short current pulse is generated. This pulse is captured by the signal transmission unit 31 and converted into an electrical signal, which is then transmitted to the integrated control system 32 through wires. The integrated control system 32 can be a microcomputer or a PLC controller, which receives the electrical signals from all contacts 3, processes and analyzes them, and finally sends a displacement signal through the prompt device 33.

[0037] Reference Figure 2 The prompting device 33 can be an audible and visual alarm, a display screen, or a wireless transmitter module. The audible and visual alarm can emit sound and light prompts when a specific location is detected, allowing operators to quickly detect it. The display screen can display the current location and other relevant information for real-time monitoring. The wireless transmitter module can send detection results to a remote server, enabling remote monitoring and data analysis.

[0038] Reference Figure 1 The guide rail 1, as the foundation of the entire device, can be made of metal materials such as stainless steel or aluminum alloy to ensure its strength and durability. The shape of the guide rail 1 can be selected according to the actual application environment. The guide rail 1 can be a straight guide rail 1 or a curved guide rail 1. The surface of the guide rail 1 can be plated to improve wear resistance and corrosion resistance.

[0039] Reference Figure 1 、 3Multiple mounting blocks 5 are bolted to the guide rail 1. Each mounting block 5 corresponds to each contact 3, and each contact 3 is mounted on a corresponding mounting block 5. Specifically, a slide groove 51 is provided on the mounting block 5 along the length of the guide rail 1. The contact 3 slides within the corresponding slide groove 51. Buffer springs 52 are provided within the slide groove 51 and on both sides of the mounting block 5. One end of the buffer spring 52 is fixedly connected to the side wall of the slide groove 51, and the other end of the ring-shaped spring is fixedly connected to the mounting block 5. This design allows the contact 3 to move freely within a certain range. When the contact 4 touches the contact 3, the buffer spring 52 can absorb the impact force from the contact 4, protecting the contact 3 from damage and extending the service life of the contact 3.

[0040] Reference Figure 3 A rocker 21 is rotatably provided on the movable frame 2, and the rotation axis of the rocker 21 is perpendicular to the length direction of the guide rail 1. The contact 4 is installed at the front end of the rocker 21, and an elastic component is provided on the movable frame 2 for driving the rocker 21 to deflect toward the guide rail 1, and under the elastic force of the elastic component, the length direction of the rocker 21 is perpendicular to the length direction of the guide rail 1; by rotatably providing the rocker 21 on the movable frame 2 and providing elastic support force to the rocker 21 through the elastic component, the contact 4 can freely adjust the angle within a certain range, avoiding a rigid collision between the contact 4 and the contact 3 when the contact 4 contacts the contact 3, resulting in breakage or bending of the contact 4 or the contact 3, further improving the reliability and accuracy of displacement signal detection; at the same time, improving the service life of the contact 4 and the contact 3.

[0041] Reference Figure 3 、 4 Specifically, the elastic component includes an elastic pressure plate 22 and a first elastic member 23. Two of the elastic pressure plates 22 and the first elastic member 23 are provided. The elastic pressure plates 22 and the first elastic members 23 form a group of two. The two elastic pressure plates 22 are both rotatably set on the mobile frame 2 and are respectively arranged on both sides of the rocker 21. The rotation axis of the pressure plate is parallel to the rotation axis of the rocker 21. The first elastic member 23 includes a first torsion spring, which is sleeved on the rotation axis of the corresponding elastic pressure plate 22. One end of the first torsion spring is fixedly connected to the mobile frame 2, and the other end of the first torsion spring is fixedly connected to the corresponding elastic pressure plate 22, for driving the corresponding elastic pressure plate 22 to deflect toward the direction close to the rocker 21.

[0042] Reference Figure 4 Contact 4 is rotatably provided with multiple rollers 41, the axes of which are parallel to the rotation axis of rocker 21. The rollers 41 provide a rolling connection with contact 3, reducing friction between contact 4 and contact 3, lowering wear and extending the service life of both. Furthermore, the design of rollers 41 ensures smoother contact between contact 4 and contact 3, avoiding damage that could result from rigid collisions and further improving the reliability and accuracy of displacement signal detection.

[0043] Reference Figure 5 、 6 The side walls on both sides of the guide rail 1 are provided with track grooves 11 along the length direction of the guide rail 1, and sliders 24 are fixedly provided on both sides of the movable frame 2. The sliders 24 are slidably provided in the track groove 11 on the corresponding side. A plurality of brackets 25 are rotatably provided on both sides of the slider 24, and a roller 26 is rotatably provided on each bracket 25. Wheel grooves 12 are provided on the side walls on both sides of the track groove along the length direction of the guide rail 1, and the rollers 26 are rotatably provided in the wheel grooves 12 on the corresponding side. The rotation axis of the roller 26 is parallel to the rotation axis of the bracket 25 and is perpendicular to the length direction of the guide rail 1.

[0044] Reference Figure 7 , the slider 24 is respectively provided with a second elastic member 27 for driving the bracket 25 to deflect away from the slider 24. The second elastic member 27 includes a second torsion spring. The second torsion spring sleeve is provided on the rotating shaft of the corresponding bracket 25. One end of the second torsion spring is fixedly connected to the slider 24, and the other end of the second torsion spring is fixedly connected to the bracket 25. This design can automatically adjust the contact area and pressure between each roller 26 and the wheel groove 12, thereby making the sliding of the movable frame 2 on the guide rail 1 smoother and more stable. At the same time, the function of the second elastic member 27 can also ensure that the roller 26 always adheres to the wheel groove 12, preventing the roller 26 from being separated from the wheel groove 12 due to vibration or other external factors, further improving the overall reliability and safety of the device.

[0045] Reference Figure 7 The cross-section of the wheel groove 12 is V-shaped, and the roller 26 is adapted to the wheel groove 12, which can reduce friction and improve sliding smoothness. At the same time, the inclined wheel groove 12 can automatically guide the roller 26, further preventing the roller 26 from deviating and then detaching from the wheel groove 12.

[0046] The implementation principle of a touch-type displacement signal device in an embodiment of the present application is as follows: when in use, the guide rail 1 is installed on the path of movement of the mobile device, and contacts 3 are installed at the key stop positions or acceleration and deceleration positions of the mobile device. The mobile frame 2 is fixed to the mobile device so that the mobile device drives the mobile frame 2 to move along the length direction of the guide rail 1. When the mobile device moves to the key stop position or acceleration and deceleration position, the contact 4 on the mobile frame 2 touches the contact 3 at the corresponding position on the guide rail 1. At the moment when the contact 4 contacts the contact 3, a short current pulse is generated. This pulse is captured by the signal transmission unit 31 and converted into an electrical signal, which is then transmitted to the integrated control system 32 through the wire. The integrated control system 32 receives the electrical signals from all contacts 3, processes and analyzes them, and finally sends a displacement signal of the mobile device at the corresponding position through the prompt device 33.

[0047] The direct contact between contact 4 and contact 3 avoids the problem that traditional photoelectric sensors and magnetic switches may be affected by environmental factors (such as dust and electromagnetic interference), thereby improving the reliability and accuracy of displacement signal detection; a physical signal can be generated the moment contact between contact 4 and contact 3, and the physical signal is quickly converted into an electrical signal through the signal transmission unit 31 and transmitted to the integrated control system 32, achieving a rapid response and ensuring the safe operation and efficient work of the mobile device.

[0048] The present application also discloses a method for sending a signal of a touch-type displacement signal device, comprising the following steps:

[0049] S1. When in use, install the guide rail 1 on the moving path of the mobile device, and install the contacts 3 at the key stop positions or acceleration and deceleration positions of the mobile device. Fix the mobile frame 2 on the mobile device so that the mobile device drives the mobile frame 2 to move along the length direction of the guide rail 1;

[0050] S2. When the mobile device moves to a critical stop position or acceleration / deceleration position, the contact 4 on the mobile frame 2 contacts the contact 3 at the corresponding position on the guide rail 1. At the moment when the contact 4 and the contact 3 contact, the signal transmission unit 31 on the contact 3 converts the physical signal generated by the contact between the contact 4 and the contact 3 into an electrical signal and transmits it to the integrated control system 32.

[0051] S3. After receiving the electrical signal transmitted by the signal transmission unit 31, the integrated control system 32 controls the prompting device 33 to prompt the displacement signal of the moving device at the corresponding position.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
