Description

Technical Field

[0001] This utility model relates to the field of positioning devices, and more specifically, to a positioning device for a CMOS color filter array film layer in a low-light system. Background Technology

[0002] Low-light imaging systems have significant applications in security monitoring, nighttime reconnaissance, and astronomical observation. CMOS image sensors, as their core components, typically employ color filter arrays (CFAs) to achieve color imaging. The CFA layer consists of red, green, and blue filter units precisely arranged according to a specific pattern (such as a Bayer array). The positioning accuracy of this arrangement directly determines the image's color reproduction, resolution, and signal-to-noise ratio.

[0003] The existing technology still has the following drawbacks: the fixed positioning method cannot compensate for assembly errors, resulting in insufficient clarity of the entire image, especially in low light conditions. At the same time, it cannot adapt to CMOS image sensors of different specifications and sizes, which limits the further development and application of low light imaging technology.

[0004] To address this, a CMOS color filter array film positioning device for a low-light system is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problems of current fixed positioning methods that cannot compensate for assembly errors, resulting in insufficient overall image clarity, especially exacerbated under low-light conditions, and the inability to adapt to CMOS image sensors of different specifications and sizes, thus limiting the further development and application of low-light imaging technology. This invention provides a CMOS color filter array film positioning device for low-light systems to solve the problems mentioned in the background.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] The present invention is as follows: a positioning device for a CMOS color filter array film layer of a low-light system, comprising a base and a CMOS body, wherein a positioning component for positioning the film layer is slidably mounted on the top of the base, and an adsorption component for fixing the film layer is slidably mounted on the top of the base, wherein the adsorption component is located inside the positioning component.

[0008] The positioning component includes a sliding groove on the top of the base, a bracket slidably installed in the sliding groove, a first motor fixedly installed on one side of the bracket, a rotating rod installed at the output end of the first motor, an electric push rod slidably installed on the rotating rod via a slider, and a positioning plate fixedly installed at the other end of the electric push rod.

[0009] As a preferred technical solution of this utility model, the adsorption assembly includes a third motor fixedly installed on one side of the base, a lead screw installed at the output end of the third motor, a limiting groove is formed on the top of the base, the lead screw is located in the limiting groove and an adsorption plate is slidably installed on the lead screw via a slider, a vacuum pump is fixedly installed on one side of the adsorption plate, and a suction tube is fixedly connected to one end of the vacuum pump.

[0010] As a preferred technical solution of this utility model, a second motor is fixedly installed on one side of the positioning plate, and a bidirectional screw is installed at the output end of the second motor. A vertical plate is slidably installed on the bidirectional screw through a thread, and there are two sets of vertical plates arranged symmetrically.

[0011] As a preferred technical solution of this utility model, a damper is fixedly installed on one side of the upright plate, a spring is fixedly connected to the other end of the damper, a washer is fixedly connected to the other end of the spring, and the inner side of the washer is tightly fitted to the outer side of the CMOS body.

[0012] As a preferred technical solution of this utility model, a placement plate is fixedly installed on the inner side of the top of the adsorption plate, and the placement plate has air holes and several groups of air holes are evenly distributed.

[0013] As a preferred technical solution of this utility model, a scale is fixedly installed on the top of the adsorption plate, and the scale is located on one side of the bracket.

[0014] As a preferred technical solution of this utility model, the adsorption plate is located inside the bracket and the adsorption plate and the lead screw slide through a matching thread in the slider, and the other end of the suction tube is through one side of the adsorption plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When the first motor is started, the motor starts to run and drives the rotating rod to rotate. The rotating rod is equipped with threads that match the slider. During the rotation of the rotating rod, the slider will move along the thread track on the rotating rod, thereby achieving precise adjustment of the position of the electric push rod. The operator can flexibly control the electric push rod to extend and retract according to the actual position of the film layer. When the electric push rod extends and retracts, it will drive the positioning plate connected to it to move up and down, thereby ensuring that the positioning plate can accurately reach the pre-set designated position, providing a reliable guarantee for the subsequent film layer positioning work.

[0017] 2. When the third motor starts, its output end drives the lead screw to rotate. The limiting groove effectively restricts the movement direction of the slider. The slider moves along the thread that matches the lead screw. When it moves, it drives the adsorption plate connected to it to move. The membrane layer to be processed is gently placed on the adsorption plate. The vacuum pump is started. The vacuum pump quickly generates a strong and stable suction force through the suction tube. The membrane layer is tightly adsorbed on the adsorption plate, thereby realizing the precise positioning and stable adsorption of the membrane layer. This greatly improves the accuracy of membrane layer positioning and effectively avoids operational errors and product defects caused by positioning deviations. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figures 1-3 and Figure 5 As shown, this embodiment proposes a CMOS color filter array film positioning device for a low-light system, including a base 1 and a CMOS body 2. A positioning component 3 for positioning the film is slidably installed on the top of the base 1, and an adsorption component 4 for fixing the film is slidably installed on the top of the base 1. The adsorption component 4 is located inside the positioning component 3.

[0029] The positioning component 3 includes a groove 301 on the top of the base 1. A bracket 302 is slidably installed in the groove 301. A first motor 303 is fixedly installed on one side of the bracket 302. A rotating rod 304 is installed at the output end of the first motor 303. An electric push rod 305 is slidably installed on the rotating rod 304 via a slider. A positioning plate 306 is fixedly installed at the other end of the electric push rod 305. When the first motor 303 is started, the motor starts to run and drives the rotating rod 304 to rotate. The rotating rod 304 is provided with threads that match the slider. During the rotation of the rotating rod 304, the slider moves along the thread track on the rotating rod 304, thereby achieving precise adjustment of the position of the electric push rod 305. The operator can flexibly control the electric push rod 305 to extend or retract according to the actual position of the film layer. When the electric push rod 305 extends or retracts, it will drive the positioning plate 306 connected to it to move up and down, thereby ensuring that the positioning plate 306 can accurately reach the preset designated position, providing a reliable guarantee for subsequent film layer positioning work.

[0030] like Figures 1-4As shown, the adsorption assembly 4 includes a third motor 401 fixedly installed on one side of the base 1. A lead screw 402 is installed at the output end of the third motor 401. A limiting groove 403 is opened on the top of the base 1. The lead screw 402 is located in the limiting groove 403 and an adsorption plate 404 is slidably installed on the lead screw 402 via a slider. A vacuum pump 405 is fixedly installed on one side of the adsorption plate 404. A suction tube 406 is fixedly connected to one end of the vacuum pump 405. When the third motor 401 starts, its output end drives the lead screw 402 to start rotating. The limiting groove 403 effectively restricts the movement direction of the slider. The slider moves along the thread that matches the lead screw 402. When it moves, it drives the adsorption plate 404 connected to it to move. The membrane layer to be processed is gently placed on the adsorption plate 404. The vacuum pump 405 is started. The vacuum pump 405 quickly generates a strong and stable suction force through the suction tube 406. The membrane layer is tightly adsorbed on the adsorption plate 404, thereby realizing the precise positioning and stable adsorption of the membrane layer. This greatly improves the accuracy of membrane layer positioning and effectively avoids operational errors and product defects caused by positioning deviations.

[0031] like Figures 1-3 and Figure 5 As shown, a second motor 3061 is fixedly mounted on one side of the positioning plate 306. A bidirectional screw 3062 is mounted on the output end of the second motor 3061. A vertical plate 3063 is slidably mounted on the bidirectional screw 3062 via threads. There are two sets of vertical plates 3063 arranged symmetrically. The two sets of vertical plates 3063 on the bidirectional screw 3062 are driven by threads that match the bidirectional screw 3062. Different threads on the bidirectional screw 3062 will cause the two sets of vertical plates 3063 to move synchronously towards or away from each other, thereby accurately positioning the CMOS body 2.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, a damper 3064 is fixedly installed on one side of the upright plate 3063. A spring 3065 is fixedly connected to the other end of the damper 3064, and a washer 3066 is fixedly connected to the other end of the spring 3065. The inner side of the washer 3066 is in close contact with the outer side of the CMOS body 2. When the upright plate 3063 moves towards the CMOS body 2 for positioning, the damper 3064 plays a buffering role, effectively reducing the impact force. Subsequently, the spring 3065 is further compressed, and its elastic force makes the washer 3066 fit tightly against the CMOS body 2, thereby achieving stable positioning of the CMOS body 2.

[0033] like Figure 3 and Figure 4As shown, a placement plate 4061 is fixedly installed on the inner top of the adsorption disk 404. The placement plate 4061 has several evenly distributed groups of air holes 4062. The membrane layer is placed on the placement plate 4061, and the air holes 4062 on the placement plate 4061 communicate with the interior of the adsorption disk 404. When the vacuum pump 405 operates, a negative pressure is created between the membrane layer and the placement plate 4061 through the air holes 4062, enhancing the adsorption effect.

[0034] like Figures 3-5 As shown, a scale 4063 is fixedly installed on the top of the adsorption plate 404, and the scale 4063 is located on one side of the bracket 302. The scale 4063 provides an intuitive position reference, which facilitates the operator to accurately control the position of the adsorption plate 404 and the positioning of the film layer, thereby improving the accuracy and efficiency of the operation.

[0035] like Figures 3-5 As shown, the adsorption plate 404 is located inside the bracket 302, and the adsorption plate 404 slides with the lead screw 402 through a matching thread in the slider. The other end of the suction tube 406 is inserted through one side of the adsorption plate 404. During operation, when the lead screw 402 rotates, the adsorption plate 404 slides along the lead screw 402 under the action of the slider because the thread in the slider matches the thread in the lead screw 402. This allows the adsorption plate 404 to be precisely adjusted in position. When the vacuum pump 405 is working, a negative pressure is formed inside the adsorption plate 404 through the suction tube 406, which greatly improves the positioning accuracy.

[0036] Specifically, in use, the CMOS color filter array film positioning device of this low-light system works as follows: The third motor 401 is started, and its output immediately drives the lead screw 402 to rotate. The limiting groove 403 effectively restricts the movement direction of the slider. The slider moves along the thread matching the lead screw 402, driving the connected adsorption plate 404 to move. The film to be processed is gently placed on the adsorption plate 404. The vacuum pump 405 is started, and the vacuum pump 405 quickly generates a strong and stable suction force through the suction tube 406. The film is tightly adsorbed onto the adsorption plate 404, thus achieving precise positioning and stable adsorption of the film, greatly improving the accuracy of film positioning and effectively avoiding problems caused by positioning deviations. To prevent operational errors and product defects, when the first motor 303 is started, the motor begins to run and drives the rotating rod 304 to rotate. The rotating rod 304 is provided with threads that match the slider. During the rotation of the rotating rod 304, the slider will move along the thread track on the rotating rod 304, thereby achieving precise adjustment of the position of the electric push rod 305. The operator can flexibly control the electric push rod 305 to extend and retract according to the actual position of the film layer. When the electric push rod 305 extends and retracts, it will drive the positioning plate 306 connected to it to move up and down, thereby ensuring that the positioning plate 306 can accurately reach the preset designated position, providing a reliable guarantee for the subsequent film layer positioning work.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
