Description

Technical Field

[0001] This utility model relates to the field of filter testing technology, specifically a filter testing mechanism. Background Technology

[0002] Optical filters are optical devices used to select the desired radiation band. A common characteristic of optical filters is that no filter can make the image of a celestial object brighter, because all filters absorb certain wavelengths, thus making the object darker. In order to ensure the quality of their products, such filters need to undergo image recognition and inspection during the production process.

[0003] Reference patent (publication number: CN222926390U; publication date: 2025-05-30) discloses a filter inspection fixture, including a base plate, two uprights fixed to the top of the base plate, a crossbeam fixed between the two uprights, a movable base plate mounted on the front surface of the crossbeam, a high-definition recognition camera mounted on the surface of the movable base plate; a stage fixed to the top of the base plate and located directly below the crossbeam, a loading groove opened on the top surface of the stage, a carrier plate placed in the loading groove, and multiple filters placed on the top of the carrier plate; and limiting mechanisms set on both sides of the stage. By improving and optimizing the filter inspection fixture in the prior art, limiting mechanisms are designed on both sides of the stage based on its original structure. These mechanisms can effectively press and limit the carrier plate placed in the loading groove, ensuring stability in the subsequent inspection process and thus ensuring the inspection effect. Moreover, the limiting mechanism is easy to operate, making it convenient for operators to pick up and put down the carrier plate after inspection.

[0004] Based on the aforementioned patents, existing testing mechanisms mostly employ a single-direction clamping plate limiting structure, which can only fix the two ends or sides of the filter. During the testing process, external forces can easily cause the filter to shift or shake, resulting in deviations in the images acquired by the testing lens and affecting the authenticity and reliability of the testing results. At the same time, as the core execution element for filter testing, the cleanliness of the lens and the stability of the optical sensor of the high-definition recognition camera directly affect the image acquisition quality. In existing testing mechanisms, most do not have a dedicated protective structure for high-definition recognition cameras, or only use a simple dust cover for protection. In non-testing states, dust and moisture in the air can easily adhere to the surface of the camera lens, causing lens contamination. In addition, the machine may also be damaged by accidental collisions. Therefore, this utility model provides a filter testing mechanism. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a filter inspection mechanism. It solves the problem that existing inspection mechanisms often use a single-direction clamping plate structure, which can only fix the filter at both ends or sides. During inspection, external forces can easily cause the filter to shift or shake, leading to deviations in the image captured by the inspection lens and affecting the authenticity and reliability of the inspection results. Furthermore, as the core execution element for filter inspection, the cleanliness of the lens and the stability of the optical sensor of the high-definition recognition camera directly affect the image acquisition quality. Most existing inspection mechanisms do not have dedicated protective structures for high-definition recognition cameras, or only use simple dust covers. In non-inspection states, dust and moisture in the air easily adhere to the camera lens surface, causing lens contamination. Additionally, the machine may be damaged by accidental collisions.

[0007] The protective component includes a support frame fixed at both ends of the mounting platform.

A slide rail bracket is fixed to the upper end of the first clamping plate. A pair of second clamping plates connected by a pushing assembly are provided inside the slide rail bracket. Rubber pads are fixed to the clamping surfaces of the second clamping plates.

[0009] Preferably, the lifting assembly includes a first electric push rod that is fixedly fixed inside the support frame, and the support slide rail is fixedly connected to the upper end of the first electric push rod.

[0010] Preferably, the threaded assembly includes a screw rotatably connected inside the support slide rail, one end of the screw is provided with a motor for driving, and is electrically mounted at one end of the support slide rail, the mounting slider is slidably connected to the inner wall of the support slide rail, and the mounting slider is threadedly connected to the screw.

[0011] Preferably, the mounting slider has horizontal plates fixed at both ends, and a second electric push rod is rotatably connected to one end of the horizontal plate via a rotating shaft. The telescopic end of the second electric push rod is rotatably connected to the protective housing via the rotating shaft. The protective housing is configured in two sets, with the two sets of protective housing located on both sides of the mounting slider. A high-definition recognition camera for detection is provided at the lower end of the mounting slider.

[0014] Beneficial effects

[0015] This invention provides a filter inspection mechanism. Compared with the prior art, it has the following advantages:

[0016] Firstly, this invention places the filter on the mounting platform. Turning the handwheel drives the bidirectional lead screw to rotate. Because the movable block is threadedly connected to the bidirectional lead screw and slides within the groove, the rotation of the bidirectional lead screw causes the two sets of movable blocks to move towards or away from each other. This causes the two sets of first clamping plates to slide on the surface of the mounting platform, achieving limiting clamping of both ends of the filter. Then, the third electric push rod is activated, extending to push the top block upwards. The top block, through the movable rod, pulls the protrusion at one end of the second clamping plate to slide within the slide rail bracket, causing the two sets of second clamping plates to move towards each other, limiting clamping the other two sides of the filter. Simultaneously, the rubber pad increases friction and provides cushioning protection, preventing damage to the filter. Through the coordinated action of the first and second clamping plates, the filter can be clamped from all four directions. The positioning clamps ensure that the filter remains fixed during testing, preventing shaking or displacement, thus improving the accuracy and stability of the test and guaranteeing the authenticity and reliability of the test results. Furthermore, operators can flexibly adjust the spacing of the first clamping plate by rotating the handwheel to accommodate different filter sizes. The push assembly, driven by a third electric push rod, precisely controls the movement distance of the second clamping plate, further enhancing the adaptability and accuracy of the clamping. Simultaneously, the rubber pads possess excellent elasticity and friction, increasing friction between the clamping plate and the filter during clamping to prevent slippage and acting as a buffer to avoid direct hard contact between the clamping plates and the filter, thus preventing surface damage and ensuring the quality and integrity of the filter.

[0017] Secondly, when not in a detection state or when the high-definition recognition camera needs protection, this utility model activates the second electric push rod, which extends and pushes the protective shell to rotate around the rotating shaft. The two sets of protective shells close, sealing and protecting the high-definition recognition camera. When detection is required, the second electric push rod retracts, pulling the protective shell open to expose the high-definition recognition camera for detection. This provides a sealed protective space for the high-definition recognition camera when not in a detection state, effectively preventing damage to the camera from dust, debris, collisions, etc., extending the camera's service life, and reducing maintenance costs.

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a filter inspection mechanism, including an installation platform 1, on which an installation mechanism for filter inspection is provided, the installation mechanism including:

[0025] The protective component includes a support frame 2 fixed at both ends of the mounting platform 1. The upper end of the support frame 2 is provided with a support slide rail 202 connected by a lifting component. The inside of the support slide rail 202 is provided with an installation slider 204 connected by a threaded component. Fixing blocks 3 are fixed on both sides of the installation slider 204. The inside of the fixing blocks 3 is provided with a protective shell 301 rotatably connected by a rotating shaft.

[0026] The clamping assembly includes a slide groove 4 inside the mounting platform 1. The slide groove 4 is provided with a first clamping plate 403 connected by an opening and closing assembly. A slide rail bracket 5 is fixed to the upper end of the first clamping plate 403. A pair of second clamping plates 504 are provided inside the slide rail bracket 5 and connected by a pushing assembly. A rubber pad 505 is fixed to the clamping surface of the second clamping plate 504.

[0027] In a preferred embodiment, the lifting assembly includes a first electric push rod 201 fixedly inserted inside the support frame 2, a support slide rail 202 fixedly connected to the upper end of the first electric push rod 201, and a threaded assembly including a screw 203 rotatably connected inside the support slide rail 202. One end of the screw 203 is provided with a motor for driving, and is electrically mounted at one end of the support slide rail 202. A mounting slider 204 is slidably connected to the inner wall of the support slide rail 202 and is threadedly connected to the screw 203, for adjusting the horizontal position and height of the high-definition recognition camera 205.

[0028] Specifically, when the height of the high-definition recognition camera 205 needs to be adjusted according to different detection scenarios or filter specifications, the first electric push rod 201 is activated. The first electric push rod 201 extends and retracts, driving the support slide rail 202 to rise or fall. Since the mounting slider 204 is connected to the support slide rail 202, the height of the high-definition recognition camera 205 can be adjusted. To adjust the horizontal position of the high-definition recognition camera 205, the motor drives the screw 203 to rotate. Because the mounting slider 204 is threadedly connected to the screw 203 and slides within the support slide rail 202, the rotation of the screw 203 will cause the mounting slider 204 to move horizontally within the support slide rail 202, thereby driving the high-definition recognition camera 205 to move horizontally. This allows the height and horizontal position of the high-definition recognition camera 205 to be flexibly adjusted, adapting to filters of different sizes, shapes, and detection positions, improving the versatility and applicability of the detection mechanism, and enhancing the accuracy and comprehensiveness of the detection.

[0029] In a preferred embodiment, horizontal plates 302 are fixed at both ends of the mounting slider 204. A second electric push rod 303 is rotatably connected to one end of the horizontal plate 302 via a rotating shaft. The telescopic end of the second electric push rod 303 is rotatably connected to the protective housing 301 via the rotating shaft. The protective housing 301 is configured in two sets, located on both sides of the mounting slider 204. A high-definition recognition camera 205 for detection is provided at the lower end of the mounting slider 204 to provide sealed protection for the high-definition recognition camera 205. In the non-detection state or when it is necessary to protect the high-definition recognition camera 205, the second electric push rod 303 is activated, extending and pushing the protective housing 301 to rotate around the rotating shaft. The two sets of protective housings 301 close, sealing and protecting the high-definition recognition camera 205. When detection is required, the second electric push rod 303 retracts, pulling the protective housing 301 open to expose the high-definition recognition camera 205 for detection.

[0030] In a preferred embodiment, the opening and closing assembly includes a bidirectional lead screw 401 rotatably connected inside the slide groove 4. One end of the bidirectional lead screw 401 is fixed with a handwheel for driving. A movable block 402 is slidably connected to the inner wall of the slide groove 4. A first clamping plate 403 is fixedly connected to the upper end of the movable block 402, and the first clamping plate 403 is configured in two sets. The two sets of first clamping plates 403 are slidably connected to the surface of the mounting platform 1. The pushing assembly includes a third electric push rod 501 fixed at the center of the upper end face of the slide rail bracket 5. A top block 502 is fixed to the upper end of the third electric push rod 501. The top block 502 has movable rods 503 rotatably connected to it via a rotating shaft on both sides. One end of the second clamping plate 504 has a protrusion, which is slidably connected to the inner wall of the slide rail bracket 5. The other end of the movable rod 503 is rotatably connected to the protrusion via a rotating shaft. The second clamping plate 504 is slidably connected to the inner wall of the first clamping plate 403. The second clamping plate 504 is configured in two sets. The first clamping plate 403 limits and clamps both ends of the filter, and then the second clamping plate 504 limits and clamps the other two sides of the filter, thereby clamping the filter in all directions.

[0031] Specifically, the filter is placed on the mounting platform 1, and the handwheel is turned to drive the bidirectional lead screw 401 to rotate. Since the movable block 402 is threadedly connected to the bidirectional lead screw 401 and slides in the slide groove 4, the rotation of the bidirectional lead screw 401 will cause the two sets of movable blocks 402 to move towards or away from each other, thereby driving the two sets of first clamping plates 403 to slide on the surface of the mounting platform 1, realizing the limiting clamping of both ends of the filter. Then, the third electric push rod 501 is activated. The third electric push rod 501 extends and pushes the top block 502 to rise. The top block 502 pulls the second clamping plate 503 through the movable rod 503. The protrusion at one end of 04 slides within the slide rail bracket 5, causing the two sets of second clamping plates 504 to move towards each other, limiting and clamping the other two sides of the filter. At the same time, the rubber pad 505 can increase friction and provide cushioning protection to prevent damage to the filter. Through the synergistic action of the first clamping plate 403 and the second clamping plate 504, the filter can be clamped in all directions, ensuring that the filter is fixed in position during the testing process and will not shake or shift, thereby improving the accuracy and stability of the test and ensuring the authenticity and reliability of the test results.

[0032] The high-definition recognition camera 205 acquires high-definition images of the target area of ​​the filter, which is existing technology and will not be elaborated on further. The first electric actuator is model DT300-200, the second electric actuator is model JME80-80, the third electric actuator is model TGA-50, and the electric actuator model is 57BYG250H, all of which are existing technologies.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] When the filter inspection work is started, the filter is first clamped and fixed: the filter is placed on the mounting platform 1, and the handwheel at one end of the bidirectional lead screw 401 in the opening and closing assembly is rotated to drive the bidirectional lead screw 401 to rotate in the slide groove 4. Because the movable block 402 is threadedly connected to the bidirectional lead screw 401 and slides along the inner wall of the slide groove 4, the two sets of movable blocks 402 move towards each other, causing the two sets of first clamping plates 403 fixed at their upper ends to slide along the surface of the mounting platform 1, thus completing the limiting clamping of both ends of the filter; then the top is started. The third electric push rod 501 in the push assembly extends and pushes the top block 502 at its upper end to rise. The top block 502 pulls the protrusion at one end of the second clamping plate 504 along the inner wall of the slide rail bracket 5 through the movable rod 503 rotatably connected on both sides, so that the two sets of second clamping plates 504 move towards each other along the inner wall of the first clamping plate 403, limiting and clamping the other two sides of the filter. The rubber pad 505 on the clamping surface of the second clamping plate 504 can increase the friction and buffer the clamping force to avoid damaging the filter.

[0035] Subsequently, the position adjustment and protection switch of the high-definition recognition camera 205 are performed: Based on the filter specifications and detection requirements, the first electric push rod 201 inside the support frame 2 of the protection assembly is activated. The first electric push rod 201 extends and retracts, causing the support slide rail 202 fixed at its upper end to rise and fall, thereby adjusting the height of the mounting slider 204 inside the support slide rail 202 and the high-definition recognition camera 205 at its lower end. Simultaneously, the motor at one end of the support slide rail 202 is activated, driving the internal screw 203 to rotate. Because the mounting slider 204 is threadedly connected to the screw 203 and along... The inner wall of the support slide rail 202 slides, and the mounting slider 204 drives the high-definition recognition camera 205 to move horizontally, so as to achieve precise adjustment of the detection position. After the adjustment is completed, the second electric push rod 303 on the horizontal plate 302 at both ends of the mounting slider 204 is activated. The second electric push rod 303 retracts and pulls the two sets of protective shells 301 in the fixing block 3 through the rotating shaft to open, so that the high-definition recognition camera 205 is exposed for detection. After the detection is completed, the second electric push rod 303 extends and pushes the protective shell 301 to close, forming a sealed protection for the high-definition recognition camera 205.
