Description

Technical Field

[0001] This invention provides a calibration device, belonging to the field of photoelectric sensor technology, and particularly relates to a photoelectric sensor alignment and calibration device. Background Technology

[0002] A photoelectric sensor is a detection element based on the photoelectric effect, converting light signals into electrical signals to detect, measure, and control objects. It is widely used in industrial automation for counting and positioning materials, and determining the presence or absence of objects, such as detecting the quantity and position of items on conveyor belts; in automobile manufacturing, it is used to check the accuracy of the installation position of automotive parts. In security monitoring, photoelectric sensors are installed in critical locations such as doors and windows; if an object blocks light, it triggers an alarm system. In medical equipment, it can be used to detect the liquid level of blood and urine samples and to detect the optical properties of biological tissues, providing assistance for medical diagnosis. In consumer electronics, the proximity sensor in a mobile phone is a type of photoelectric sensor used to detect whether the phone is close to a person's face, thus enabling automatic screen-off or on / off functionality. Furthermore, it is used in environmental monitoring, such as detecting light intensity and air quality, supporting the collection of environmental data. In short, photoelectric sensors, with their advantages of high sensitivity, fast response speed, and non-contact detection, play a vital role in many fields and are an indispensable part of modern technology.

[0003] The advantage of aligning and calibrating two photoelectric sensors is that it significantly improves detection accuracy and reliability. For example, in industrial automated production lines, precisely aligned photoelectric sensors enable high-precision material positioning and quality inspection. In medical devices, such as endoscopes, aligned and calibrated photoelectric sensors can more accurately capture images of the surgical area. Furthermore, in the field of security monitoring, aligned photoelectric sensors can achieve more precise target detection and alarms.

[0004] However, misalignment of photoelectric sensors can lead to numerous adverse consequences. For example, in industrial production, it may result in inaccurate material positioning, affecting production efficiency and product quality. In the medical field, misaligned sensors may fail to accurately capture images, impacting diagnostic results. In security monitoring, misalignment can lead to false alarms or missed alarms, reducing system reliability. Therefore, ensuring the alignment and calibration of photoelectric sensors is crucial for their application in various fields. Utility Model Content

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] This invention provides a photoelectric sensor alignment and calibration device. Utilizing a symmetrically distributed adjustment structure on the base, it includes a fixing component, an adjusting component, and a threaded rod. The fixing component houses the photoelectric sensor body, and through the cooperation of a baffle and the threaded rod, precise alignment and calibration of the sensor are achieved.

[0025] like Figure 1 and Figure 2As shown, a photoelectric sensor alignment and calibration device includes a base 1. A symmetrically distributed adjustment structure 2 is provided above the base 1. The adjustment structure 2 includes a fixing member 21, an adjusting member 22, and a threaded rod 23. The fixing member 21 is positioned above the adjusting member 22, and a photoelectric sensor body is disposed inside the fixing member 21. A baffle 15, movably connected to the fixing member 21, is provided on one side of the fixing member 21. The threaded rod 23 passes through the adjusting member 22. The base 1 has a sliding groove 11 corresponding to the adjustment structure 2, and fixed ends 12 corresponding to the sliding member 22 are provided on both sides inside the sliding groove 11.

[0026] In this embodiment, the sliding groove 11 allows the adjusting member 22 to slide freely within it, thereby achieving precise adjustment of the photoelectric sensor's position. The fixed end 12 ensures stable movement of the adjusting member 22 within the sliding groove 11, preventing it from shifting or wobbling during adjustment. One end of the threaded rod 23 is fixedly connected to the adjusting member 22, while the other end passes through the fixed member 21 and is rotatable. By rotating the threaded rod 23, the movement distance of the adjusting member 22 can be precisely controlled, thereby adjusting the position of the fixed member 21. The baffle 15 is movably connected to the fixed member 21, serving a positioning and alignment function during installation and calibration. This structural design enables rapid and precise alignment and calibration of the photoelectric sensor.

[0027] This design improves the accuracy of photoelectric sensor alignment and calibration, reduces errors from manual operation, and enhances the stability and reliability of the calibration process. Precise control of the threaded rod 23 allows for micron-level adjustments, ensuring sensor alignment accuracy. Simultaneously, the design of the sliding groove 11 and fixed end 12 ensures stable movement of the adjusting component 22, preventing wobbling and misalignment during adjustment. The use of the baffle 15 simplifies the installation and calibration process, making operation more convenient and efficient. Furthermore, this structural design offers good versatility and adaptability, making it suitable for different models and specifications of photoelectric sensors, thus possessing broad application prospects.

[0028] like Figure 2 and Figure 3 As shown, a sliding rod 13 is provided between the fixed ends 12, which is placed on both sides of the threaded rod 23 and passes through the adjusting member 22. The threaded rod 23 passes through any of the fixed ends 12. A knob 14 that passes through the base 1 is fixedly connected to the end of the threaded rod 23. A bolt structure 25 passes through the baffle 15. The length of the baffle 15 is greater than the distance between the adjusting structures 2.

[0029] In this embodiment, the coordinated use of the slide bar 13 and the threaded rod 23 enables precise control of the photoelectric sensor position, improving calibration accuracy and efficiency. The knob 14 design makes operation more intuitive and convenient, allowing even non-professionals to quickly master the calibration method. The combination of the bolt structure 25 and the baffle 15 provides a simple and effective fixing and alignment method, reducing errors during calibration. Furthermore, this structural design offers good scalability; the length of the baffle 15 can be adjusted as needed to accommodate adjustment structures 2 with different spacing, thereby improving the device's versatility and applicability. In summary, this photoelectric sensor alignment calibration device, through its unique structural design, significantly improves calibration accuracy and stability, reduces operational difficulty, and possesses high practical value.

[0030] In use, firstly, the photoelectric sensor body is installed inside the fixing member 21, ensuring alignment and fixation between the sensor and the fixing member 21. Then, the adjusting structure 2 is installed on the base 1, allowing the adjusting member 22 to slide freely on the base 1 through the cooperation of the sliding groove 11 and the fixed end 12. Next, the baffle 15 is installed on one side of the fixing member 21 and fixed with bolts 25, ensuring that the length of the baffle 15 is greater than the distance between the adjusting structures 2 for alignment. Subsequently, rotating the knob 14 rotates the threaded rod 23, which in turn moves the adjusting member 22 within the sliding groove 11, achieving initial adjustment of the photoelectric sensor's position. After initial adjustment, the sliding rod 13 restricts the movement trajectory of the adjusting member 22, ensuring precise linear movement when the threaded rod 23 rotates, thereby improving the accuracy of alignment and calibration. Finally, the fine-tuning knob 14 is used to finely adjust the position of the photoelectric sensor until the required alignment and calibration accuracy is achieved. Throughout the process, the cooperation between the baffle 15 and the fixing member 21 simplifies the installation and calibration process, making operation more convenient and efficient.
