Description
Technical Field
[0001] This utility model relates to the field of sensor detection technology, specifically to a photoelectric speed sensor processing and testing platform. Background Technology
[0002] In modern industry and technology, photoelectric speed sensors, with their significant advantages such as non-contact operation, high precision, high resolution, high reliability, and fast response, are widely used in various detection and control scenarios, including motor speed monitoring, mechanical manufacturing process control, and aerospace equipment operation monitoring. As an angular displacement sensor, it achieves accurate speed measurement through the coordinated work of a slotted disk mounted on the measured shaft, a light source, photoelectric devices, and an indicating slotted disk. However, the processing and testing of photoelectric speed sensors face many severe challenges. On the one hand, special light in the processing and testing environment, such as ultraviolet light and strong infrared light, can easily interfere with the sensor's detection process. These special light rays may be misidentified by the photoelectric devices, leading to large errors in the detection results and significantly reducing the accuracy of the sensor in subsequent practical applications. For example, in some optical instrument production workshops, stray light from the surrounding environment can interfere with the normal detection of the sensor, reduce its measurement accuracy, and thus affect the quality of the entire product.
[0003] On the other hand, the processing and testing environment often contains a lot of dust, oil and other pollutants. These pollutants can easily adhere to the key components of photoelectric speed sensors, such as slit discs and the surface of photoelectric devices. Dust accumulation will block the propagation of light, affect the reception and transmission of light signals, and lead to a decrease in the detection accuracy of the device or even failure. Oil may corrode the electronic components of the sensor, damage the sensor, greatly shorten the service life of the sensor, and increase the production and maintenance costs. To address this, we propose a photoelectric speed sensor processing and testing platform. Utility Model Content

[0033] Structural Description:
[0034] Work support frame 1: As the basic support component of the entire testing table, it provides an installation platform for other components. The motor mounting groove 9 in the middle of the top surface is adapted to the size of the rotary drive motor 13. The motor is firmly fixed by bolts and other means to ensure the stability of the motor during operation. The front sliding groove 8 on the front side is smooth and has a reasonable width and depth design to provide a precise sliding track for the front sealing sliding plate 3 to ensure its smooth sliding. The side mounting grooves 10 distributed at equal intervals on the side can be used to install additional auxiliary equipment, such as lighting devices, sensor calibration equipment, etc., to enhance the functionality of the testing table.
[0035] The detection support frame 4 is fixed on the top surface of the working support frame 1 and serves to connect and support other key components. The side mounting holes 20 are evenly distributed on the side, and the hole diameter matches the pipe diameter of the air inlet guide pipe 2 and the air outlet guide pipe 7. The guide pipes are fixed by welding, screw connection and other methods to ensure a firm connection and good sealing. The internal sliding groove 18 on the front side cooperates with the front sliding groove 8 to provide double guidance for the front sealing sliding plate 3, so that it will not deviate during the sliding process. The front locking sliding groove 19 has a groove shape that matches the locking fixing slide rod 5. It is used to accurately position and fix the locking fixing slide rod 5, thereby enhancing the stability of the front sealing sliding plate 3.
[0036] Rotation drive motor 13: Installed in motor mounting slot 9, the output shaft of the motor is fixedly connected to the rotation support platform 17. The motor has appropriate torque and speed, which can stably drive the rotation support platform 17 to rotate, simulating the rotation condition of the photoelectric speed sensor in actual use, and providing power support for detection.
[0037] Top detection camera 15: Fixed inside the top surface of the detection support frame 4, with the lens facing downwards. Its shooting angle can cover the sensor on the rotating support platform 17. The camera has high resolution and good light sensitivity, and can clearly capture the details of the sensor during the rotation process, such as the rotation of the slit disc, the working status of the photoelectric device, etc., to provide intuitive image data for detection.
[0038] Rotating support platform 17: slides on the top surface of the working support frame 1. The threaded holes on its top side are evenly distributed and have uniform thread specifications. They are used to install the clamping screw 14. The surface of the rotating support platform 17 is flat and smooth, and it has good contact with the side clamping slide plate 16 to ensure that the side clamping slide plate 16 can slide smoothly. At the same time, it maintains balance during rotation to ensure that the sensor is fixed and stable.
[0039] Clamping screw 14: It is threaded into the threaded hole on the side of the rotating support table 17. The length and pitch of the screw are carefully designed. When the screw is rotated, the side clamping slide plate 16 can be moved precisely, thereby clamping the sensor firmly. The outer end of the screw is usually designed with a handle or interface for easy operation, so that the operator can easily rotate the screw.
[0040] Side clamping slide plate 16: Rotatably connected to the inner end of the clamping screw 14 and slides on the top surface of the rotating support platform 17. The clamping surface of the slide plate is usually made of soft materials such as rubber, which can increase friction and ensure clamping effect, and avoid scratching the sensor surface. The shape and size of the slide plate are compatible with common photoelectric speed sensors, and can clamp the sensor evenly from the side.
[0041] Front sealing sliding plate 3: It slides in the front sliding groove 8 of the working support frame 1 and the inner sliding groove 18 of the detection support frame 4 respectively. The sealing sliding plate is made of a material with good light-shielding performance, such as black plastic or metal plate, which can effectively block special light from entering the detection area. The thickness and strength of the plate are moderate, ensuring that it is not easily deformed during sliding and has a good sealing effect.
[0042] The locking and fixing slide rod 5 slides in the locking groove 19 and is locked into the inside of the side of the front sealing sliding plate 3. The diameter of the slide rod matches the locking groove 19 and the locking hole on the front sealing sliding plate 3. The length of the slide rod is moderate, which can ensure the fixing effect without affecting the normal sliding of the front sealing sliding plate 3. The two ends of the slide rod are usually designed with protrusions or pull rings for easy operation, so that the operator can easily insert and remove the slide rod.
[0043] Side sealing rotating shaft 6: Installed inside the exhaust guide pipe 7, the shaft body and the exhaust guide pipe 7 are connected by a sealed bearing to ensure flexible rotation and good sealing. The length and diameter of the side sealing rotating shaft 6 are designed according to the size of the exhaust guide pipe 7, which can stably support the side sealing rotating plate 21 and drive it to rotate.
[0044] Air intake dust removal filter plate 11: fixed on the inner bottom surface of the air intake guide pipe 2. The filter plate is made of high-efficiency filter material, such as multi-layer fiber filter or activated carbon filter, which can effectively filter dust, impurities and some harmful gases in the air. The area of the filter plate is matched with the cross-sectional area of the air intake guide pipe 2 to ensure that the air can be fully filtered before entering the detection area.
[0045] Dust removal fan 12: Fixed inside the air inlet guide pipe 2. The fan blades are reasonably designed to generate sufficient suction to draw outside air into the air inlet guide pipe 2. The power and speed of the fan are selected according to the size of the testing station and the ventilation requirements to ensure that a stable ventilation volume is provided and to maintain air circulation in the testing area.
[0046] Side sealing rotating plate 21: Rotarily connected to the outside of the side sealing rotating shaft 6 and slides inside the exhaust guide pipe 7. The rotating plate is made of a material with good sealing performance, such as rubber or silicone, which can effectively adjust the ventilation volume and prevent dust from flowing back into the detection area from the exhaust guide pipe 7. The shape and size of the rotating plate are adapted to the exhaust guide pipe 7 to ensure good sealing during rotation and sliding.
[0047] Exhaust dust filter 22: Fixed to the bottom of the exhaust guide pipe 7. The filtration accuracy of the filter is matched with that of the inlet dust filter plate 11. It can further filter the dust in the exhaust air and prevent the dust from re-entering the detection area. The filter is easy to disassemble and clean, ensuring the durability of its filtration effect.
[0048] Working Principle: When this utility model is needed, the photoelectric speed sensor to be tested is placed on the rotating support platform 17. The clamping screw 14 is rotated. Since the clamping screw 14 is threadedly connected to the threaded hole on the side of the rotating support platform 17, and the inner end is rotatably connected to the side clamping slide plate 16, as the screw rotates, the side clamping slide plate 16 slides on the top surface of the rotating support platform 17, gradually approaching and clamping the sensor, completing the positioning and fixing of the sensor, providing a stable foundation for subsequent testing. The rotation drive motor 13 is started, and its output shaft drives the rotating support platform 17 to rotate, simulating the rotation state of the photoelectric speed sensor in actual use. At this time, the top detection camera 15 on the top surface inside the detection support frame 4 starts to work, taking pictures and recording the rotating sensor from above, monitoring various states of the sensor during the rotation process, such as the rotation of the slotted disc, the working state of the photoelectric device, etc., to achieve the detection of the sensor. Before testing, the front sealing sliding plate 3 is pushed to make it on the working support frame. The front sliding groove 8 of the test support frame 4 slides within the inner sliding groove 18, sealing the test area. Simultaneously, the locking and fixing slide rod 5 slides along the locking groove 19, locking it into the inner side of the front sealing sliding plate 3, further fixing the position of the front sealing sliding plate 3 and blocking special light from entering the test area, thus avoiding light interference with the test results. The dust removal fan 12 in the air inlet guide pipe 2 is turned on, and the fan generates suction to draw outside air into the air inlet guide pipe 2. Before entering the test area, the air passes through the air inlet dust removal filter plate 11, which filters out dust and other impurities in the air. The purified air enters the test area and enters the exhaust guide pipe 7. The side sealing rotating plate 21 rotates with the side sealing rotating shaft 6 to adjust the ventilation volume. The exhaust dust removal filter 22 prevents dust in the test area from being discharged through the exhaust guide pipe 7 and then re-entering, continuously keeping the air in the test area clean, reducing dust contamination of the sensor, and ensuring the stability of the test environment.
