Description

Technical Field

[0001] The utility model relates to the technical field of optical experiment optical path control instruments and equipment, in particular to a novel multi-channel controlled electric diaphragm device. Background Technique

[0002] A diaphragm is an element that restricts the light beam in an optical system. Its functions in an optical system are as follows: restricting the beam size. In an imaging system, the diaphragm can control the light energy passing through the system. For example, in a camera, the size of the aperture (a type of diaphragm) determines the amount of light entering the camera lens. The larger the aperture (the larger the diaphragm aperture), the more light energy reaches the imaging sensor within the same exposure time, and the brighter the image; conversely, the image is darker. Controlling the imaging quality, the diaphragm can limit the solid angle of the imaging light beam and reduce the influence of aberrations. By reasonably selecting the position and size of the diaphragm, the imaging quality of the optical system can be optimized. For example, in the design of some complex optical lenses, the diaphragm position is adjusted to balance various aberrations such as spherical aberration, coma, and astigmatism, thereby making the imaging clearer and more realistic. Determining the field of view range, the field stop determines the object space or image space range that the optical system can image. It defines the object area that can be clearly imaged by the optical system. For example, in a telescope, the field stop determines the sky range that the observer can see; in a microscope, it determines the size of the area on the sample that can be observed.

[0003] The main components of a diaphragm device are as follows: 1. The diaphragm plate has various shapes: Usually, the diaphragm plate is circular, and there is an adjustable light passing hole in its center. It is generally made of metal (such as stainless steel) because metal has good strength and stability and can maintain its shape under various environments. At the same time, the metal surface can be specially treated (such as blackening) to reduce light reflection and improve the performance of the optical system. 2. Adjusting mechanism: Manual adjustment is one of the most common adjustment methods. Usually, a mechanical structure such as a threaded sleeve, a rack and pinion, or a cam mechanism is used to change the size of the light passing hole of the diaphragm plate. The manual adjustment mechanism is simple, reliable, and low-cost. In some optical devices with a high degree of automation, an electric adjustment mechanism is adopted. This adjustment method usually consists of a motor (such as a stepper motor, a DC motor, etc.), a transmission mechanism (such as a belt drive, a gear drive, etc.), and a control system. It is suitable for complex optical systems and application scenarios that require fast response. 3. Fixing structure: The diaphragm device usually has a housing for protecting the internal diaphragm plate and adjusting mechanism. The housing can prevent impurities such as dust and water vapor from entering the diaphragm device and affecting its performance.

[0004] Existing electric aperture devices generally use a mechanical structure of rotating gears to perform the opening and closing actions of the aperture device. This control mechanism based on rotating gears has obvious defects. The control accuracy of the aperture size of the aperture device is poor. Specifically, when adjusting the size of the aperture, there is often a large error range. Whether it is necessary to make subtle adjustments or to change the size of the aperture significantly, it is difficult to achieve precise control. This inaccuracy makes the device unable to meet actual needs in many usage scenarios with high precision requirements. At the same time, when light enters the system, due to the lack of effective light guidance and refraction mechanism design, the light presents a relatively chaotic state during the propagation process and cannot be accurately refracted into the aperture of the aperture. This results in low light utilization and affects the performance of the entire optical system, such as reduced imaging quality, weakened signal strength, and a series of problems related to the effective utilization and transmission of light.

The diaphragm pump machine 217 on the pump body 210 drives the eccentric wheel 216 to rotate, prompting the diaphragm moving rod 215 on the eccentric wheel 216 to drive the elastic diaphragm 214 to quantitatively suck the clear water in the water storage tank 207 into the pump body 210 through the water inlet pipe 206, and then pump it into the lens holder 2 through the water delivery pipe 204. On the left and right sides of the bottom inner side of the pump body 210, through holes 213 are opened, and a one-way gasket 212 is arranged in the middle of the inside of the through holes 213.

By driving the moving lead screw 302 to rotate with the moving disk 304, the lens holder 2 on the moving block 303 is controlled to move in position on the moving guide rail 301. A leak-proof snap mechanism for preventing the leakage of clear water after pumping is completed. The leak-proof snap mechanism includes a leak-proof clip body 4, a leak-proof snap plate 402 is rotatably connected to the bottom part inside the leak-proof clip body 4, a leak-proof snap block 401 is fixedly connected to the middle part of the left end of the leak-proof snap plate 402, rotating pins 403 are fixedly connected to the bottom parts of the front and rear ends of the leak-proof snap plate 402, limit catches 404 are fixedly connected to the middle upper parts of the front and rear ends of the leak-proof snap plate 402, and a number of limit grooves 405 are equidistantly opened on the front and rear sides of the top part inside the leak-proof clip body 4. When the appropriate water pressure is reached, to prevent the leakage of clear water inside the lens holder 2, the leak-proof snap plate 402 is triggered, so that the limit catches 404 on the leak-proof snap plate 402 are in the limit grooves 405 on the leak-proof clip body 4, and the leak-proof snap block 401 and the leak-proof clip body 4 cooperate to compress the water delivery pipe 204 to prevent leakage. The moving guide rail 301 and the bottom end of the diaphragm holder 114 are fixedly connected to the top of the bottom plate 3 for the fixed support of the displacement control mechanism and the diaphragm adjustment mechanism.

[0044] Working principle: The telescopic electric cylinder 1 drives the movable seat 102 on the support rod 101 to move up and down, prompting the movable seat 102 to drive the movable rod 104 on the rotating disk 105 to rotate at an angle, so that the angle scale disk 115 on the rotating disk 105 is precisely controlled by the precision pointer 113 to rotate the angle. At the same time, the rotating disk 105 drives the linkage disk 107 to rotate, and the rotating linkage disk 107 drives the linkage shaft 109 on the diaphragm plate 108 to control the opening and closing size of the diaphragm plate 108 in the linkage groove 116. The limiting rod 110 on the diaphragm plate 108 slides in the sliding groove 112 in the sliding disk 111 to perform the linkage opening and closing of the diaphragm plate 108. The rotary telescopic motor 208 on the diaphragm pump frame 205 controls the pump body 210 to adjust the height and the inlet and outlet directions, so that the one-way valve body at the inlet and outlet of the pump body 210 is connected to the water delivery pipe 204 and the water inlet pipe 206. The diaphragm pump machine 217 on the pump body 210 drives the eccentric wheel 216 to rotate, prompting the diaphragm moving rod 215 on the eccentric wheel 216 to drive the elastic diaphragm 214 to quantitatively suck the clear water in the water storage tank 207 into the pump body 210 through the water inlet pipe 206, and then pump it to the lens holder 2 through the water delivery pipe 204. During pumping, first unscrew the sealing cover 203 from the exhaust pipe 202 to empty the air in the lens holder 2 first, and then screw the sealing cover 203 onto the exhaust pipe 202 for sealing. The pumped clear water causes the elastic lens 201 to deform due to the water pressure, thereby making the light generate a focusing or scattering effect, so as to achieve the guidance of light. When the appropriate water pressure is reached, to prevent the clear water in the lens holder 2 from leaking, pull the anti-leakage buckle plate 402, so that the limiting buckle 404 on the anti-leakage buckle plate 402 is in the limiting groove 405 on the anti-leakage clamp body 4, prompting the anti-leakage buckle block 401 to cooperate with the anti-leakage clamp body 4 to press the water delivery pipe 204 to prevent leakage. The moving disk 304 drives the moving lead screw 302 to rotate, prompting the lens holder 2 on the moving block 303 to control the position movement on the moving guide rail 301.
