Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a camera based on servo motor-driven focusing. Background Technology

[0002] Servo motors, as core power devices, are widely used in high-precision control systems such as CNC machine tools, industrial robots, and automated production lines. In order to achieve real-time and accurate monitoring of the operating status of servo motors, it is often necessary to use cameras to acquire relevant image information of servo motors, and then obtain key data such as speed synchronization through image analysis and processing.

[0003] In traditional camera applications, the camera's position is relatively fixed after installation, making it difficult to quickly adjust according to actual usage needs. For example, in some servo motor monitoring scenarios, the distance between the camera and the servo motor under test is usually preset and difficult to change once installed. However, in practical applications, due to the different sizes and operating environments of various servo motor models, when the distance between the camera and the servo motor under test is too far, a large amount of image detail will be lost, becoming blurry. In synchronous speed monitoring, this blurry image will lead to a significant decrease in the accuracy of reading key parameters such as servo motor speed. Conversely, if the distance between the camera and the servo motor under test is too close, cameras have a specific depth of field range. When the distance exceeds this range, the camera will have difficulty achieving accurate focus. Focusing difficulties will also result in unclear images, failing to provide effective information for subsequent data processing. Therefore, we have introduced a new camera based on servo motor-driven focusing. Utility Model Content

[0004] The main objective of this invention is to provide a camera based on servo motor-driven focusing, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A servo motor-driven focusing camera includes a drive base, a displacement mechanism fixedly mounted at the rear end of the drive base, a drive groove inside the drive base, a connecting groove in the middle of the upper end of the drive base, sliding grooves in the lower left and lower right ends of the drive base, a pressing mechanism fixedly connected to the upper end of the displacement mechanism, a camera body installed inside the pressing mechanism, and a mounting base plate fixedly connected to the lower end of the drive base, with mounting holes at the four corners of the upper end of the mounting base plate.

[0006] Preferably, the displacement mechanism includes a micro motor, a threaded rod is fixedly installed at the output end of the micro motor, a movable sleeve is movably connected to the outer surface of the threaded rod, a connecting strip is fixedly connected to the upper part of the outer surface of the movable sleeve, a support plate is fixedly connected to the upper end of the connecting strip, an extension plate is fixedly connected to the lower left and lower right parts of the support plate, and a slide bar is fixedly connected to the lower part of the two extension plates near the movable sleeve.

[0007] Preferably, the micro motor is fixedly mounted at the rear end of the drive seat, and the end of the threaded rod away from the micro motor is movably connected to the front wall of the drive groove through a bearing.

[0008] By adopting the above technical solution, the micro motor is installed behind the drive unit, which facilitates the maintenance of the micro motor.

[0009] Preferably, the movable sleeve is located inside the drive groove, and the connecting strip is slidably connected to the connecting groove.

[0010] By adopting the above technical solution, the movable sleeve can move back and forth following the rotation of the threaded rod.

[0011] Preferably, the tray and the two extension plates do not contact the drive seat, and the two slide bars are slidably connected to the two slide grooves respectively.

[0012] By adopting the above technical solution, two sliders slide inside two grooves respectively, so that the pallet can remain stable when moving.

[0013] Preferably, the clamping mechanism includes a mounting base, with connecting frames fixedly connected to the upper front and upper rear of the mounting base, and rotating rods threadedly connected to the upper middle of the two connecting frames, with a handle fixedly connected to the upper end of each of the two rotating rods, and a clamping pad fixedly connected to the lower end of each of the two rotating rods.

[0014] Preferably, the lower end of the mounting base is fixedly connected to the support plate, and the lower ends of both clamping pads are tightly fitted to the camera body.

[0015] By adopting the above technical solution, the clamping pad can press and fix the top of the camera body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By starting the micro motor, the micro motor drives the threaded rod to rotate and move the movable sleeve back and forth, thereby enabling the support plate connected to the movable sleeve and the camera body installed on it to move back and forth. This allows the distance between the camera body and the servo motor under test to be adjusted, so that the camera body can obtain a clear image at the optimal shooting distance. This avoids blurry image details and affects the accuracy of speed synchronization data reading due to excessive distance, or difficulty in focusing due to excessive distance exceeding the depth of field range of the camera body. 2. By placing the camera body inside the mounting base and rotating the two handles, the two rotating rods, along with the two clamping pads, press and fix the camera body above it. This prevents the camera from shifting or shaking due to external vibration interference during the servo motor speed synchronization test, ensuring stable and clear images and preventing image jitter from affecting the accurate acquisition and analysis of servo motor operating status data.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: A servo motor-driven focusing camera includes a drive base 1, a displacement mechanism 2 fixedly mounted at the rear end of the drive base 1, a drive groove 3 inside the drive base 1, a connecting groove 4 in the middle of the upper end of the drive base 1, sliding grooves 5 in the lower left and lower right ends of the drive base 1, a pressing mechanism 6 fixedly connected to the upper end of the displacement mechanism 2, a camera body 7 installed inside the pressing mechanism 6, and a mounting base plate 8 fixedly connected to the lower end of the drive base 1, with mounting holes 9 at the four corners of the upper end of the mounting base plate 8.

[0023] In this embodiment, the displacement mechanism 2 includes a micro motor 21. A threaded rod 22 is fixedly installed at the output end of the micro motor 21. A movable sleeve 23 is movably connected to the outer surface of the threaded rod 22. A connecting strip 24 is fixedly connected to the upper part of the outer surface of the movable sleeve 23. A support plate 25 is fixedly connected to the upper end of the connecting strip 24. An extension plate 26 is fixedly connected to the lower left and lower right parts of the support plate 25. A slide bar 27 is fixedly connected to the lower part of the two extension plates 26 near the movable sleeve 23. The micro motor 21 is fixedly installed at the rear end of the drive seat 1. The end of the threaded rod 22 away from the micro motor 21 is movably connected to the inner front wall of the drive groove 3 through a bearing. The movable sleeve 23 is located inside the drive groove 3. The connecting strip 24 is slidably connected to the connecting groove 4. The support plate 25 and the two extension plates 26 do not contact the drive seat 1. The two slide bars 27 are slidably connected to the two slide grooves 5 respectively.

[0024] The above solution involves starting the micro motor 21, which drives the threaded rod 22 to rotate and move the movable sleeve 23 back and forth. This allows the support plate 25 connected to the movable sleeve 23 and the camera body 7 mounted on it to move back and forth, thereby enabling the adjustment of the distance between the camera body 7 and the servo motor under test.

[0025] In this embodiment, the clamping mechanism 6 includes a mounting base 61. A connecting frame 62 is fixedly connected to the front and rear of the upper end of the mounting base 61. A rotating rod 63 is threaded through the middle of the upper end of each of the two connecting frames 62. A handle 64 is fixedly connected to the upper end of each of the two rotating rods 63. A clamping pad 65 is fixedly connected to the lower end of each of the two rotating rods 63. The lower end of the mounting base 61 is fixedly connected to the support plate 25. The lower ends of the two clamping pads 65 are tightly fitted to the camera body 7.

[0026] The above solution involves placing the camera body 7 inside the mounting base 61 and rotating the two handles 64 to press and fix the camera body 7 with the two rods 63 and the two pressure pads 65.

[0027] It should be noted that this utility model is a camera based on servo motor-driven focusing. In actual use, the two handles 64 are first manually rotated to drive the rotating rod 63 to generate linkage, so that the two pressure pads 65 connected to it can press and fix the camera body 7 from above, ensuring that the camera body 7 remains stable in the mounting base 61 and resists external vibration interference. When it is necessary to adjust the distance between the camera body 7 and the servo motor under test, the micro motor 21 is started. After the micro motor 21 starts running, it will drive the threaded rod 22 to rotate. Since the movable sleeve 23 is threadedly connected to the threaded rod 22, under the action of the rotation of the threaded rod 22, the movable sleeve 23 will move back and forth along the axial direction of the threaded rod 22. During the movement of the movable sleeve 23, it will drive the connected support plate 25 to move together, while the camera body... Camera 7 is mounted above the support plate 25, so moving the support plate 25 will cause the camera body 7 to move back and forth as well. This allows for adjustment of the distance between the camera body 7 and the servo motor under test. If the distance between the camera body 7 and the servo motor under test is too far, the details of the image captured by the camera body 7 will become blurry, affecting the accuracy of reading the speed synchronization data and resulting in inaccurate data. This, in turn, affects subsequent analysis and judgment. If the distance is too close, it may exceed the depth of field range of the camera body 7, making it difficult for the camera body 7 to focus and also preventing the acquisition of a clear image. By adjusting the distance between the camera body 7 and the servo motor under test, it is possible to ensure that the camera body 7 is always at the optimal shooting distance, thereby acquiring clear and accurate images and providing a reliable foundation for subsequent data processing and analysis.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
