[0037] like Figures 1 to 3 As shown, in one embodiment of the utility model, a camera focusing mechanism is involved, including:

[0038] A workbench 1 is provided with a camera fixture 11, and a placement slot is provided on the camera fixture 11. The placement slot is used to place the camera 4 to be focused. The camera fixture 11 is used to fix and position the camera 4 to be focused, and provide corresponding electrical, optical or mechanical interfaces for testing, debugging and calibration. The design of the camera fixture 11 can be determined according to the size, interface type (such as USB, HDM I, RJ45, etc.), control signal requirements, etc. of the camera 4 to be focused. According to the design of the camera fixture 11, the camera 4 to be focused is placed in the placement slot, and the camera 4 to be focused is ensured to be aligned with the interface of the camera fixture 11, and adjusted in the required direction or angle. According to the interface type of the camera 4 to be focused, the camera 4 to be focused is connected to the interface on the camera fixture 11 using a corresponding cable or connector.

[0039] Focusing assembly 2, the focusing assembly 2 includes a pneumatic element 21, a first cantilever 22 and a second cantilever 23, the first cantilever 22 and the second cantilever 23 are installed on the top of the pneumatic element 21, and the pneumatic element 21 is an element that uses compressed air or gas for power transmission and control. Common pneumatic elements 21 include cylinders, air valves, air control elements, etc. In some embodiments, the first cantilever 22 and the second cantilever 23 can be connected to the cylinder through bearings. For example, the bearing seat or bracket for installing the first cantilever 22 and the second cantilever 23 is installed in a predetermined position and fixed, and the pipes at the inlet and outlet of the cylinder are connected to connect the cylinder to the gas source. It should be noted that the selection and fixing method of the bearing seat or bracket of the cantilever should be designed according to the specific application and working environment, and it is necessary to ensure that the cantilever can rotate freely and has sufficient strength and stability. Similarly, the selection and installation of the cylinder should also be determined according to the specific application requirements.

[0040] A first focusing module is disposed at the end of the first cantilever 22 , and a second focusing module is disposed at the end of the second cantilever 23 . The first focusing module and the second focusing module are used to focus the camera 4 to be focused. Figure 4 The camera 4 to be focused according to the embodiment of the present disclosure is shown as follows. Figure 4As shown, in order to facilitate assembly and fixation, the lens of the camera to be focused 4 is connected to the base through a threaded connection. During the production process, the relative position between the lens and the image sensor is changed by turning the lens knob to achieve the purpose of changing the focal length. The lens is a smooth cylinder without teeth. During the production of the camera, the main way to adjust the focal length of the lens is usually to adjust it by a manual knob. In the embodiment of the present disclosure, the camera to be focused 4 is focused by the first focusing module and the second focusing module, replacing the manual knob lens, to achieve automated production, and has low production cost, small space occupation, and high efficiency.

[0041] The first focusing module includes a first rotating wheel 222, and the second focusing module includes a second rotating wheel 232. The first rotating wheel 222 and the second rotating wheel 232 are used to clamp and drive the lens of the camera 4 to be focused to rotate, so as to achieve the focusing of the camera 4 to be focused;

[0042] For example, Figure 4 As shown, the lens of the camera 4 to be focused is provided with an outer adjustment ring 41, and the outer adjustment ring 41 is a position for rotation and adjustment. In the disclosed embodiment, the first rotating wheel 222 and the second rotating wheel 232 clamp and drive the outer adjustment ring 41 to rotate, and continuously adjust the adjustment mechanism in the camera 4 to be focused until the best focus is found. When the first rotating wheel 222 and the second rotating wheel 232 rotate the outer adjustment ring 41, the mechanical structure inside the lens will move accordingly, changing the distance between the lens and the imaging sensor, thereby achieving automatic focus, without the need to manually turn the knob to focus the lens, and the focus operation can be completed quickly and accurately, greatly improving production efficiency. In the large-scale camera production process, automatic focusing can significantly reduce manual intervention, reduce production costs, and ensure that each camera produced can achieve the best focus state, thereby improving the quality stability of the product, and can also avoid product damage caused by manual operation errors, reducing production risks.

[0043] The pneumatic element 21 is used to control the first cantilever 22 and the second cantilever 23 to move in the horizontal direction, so that the first rotating wheel 222 and the second rotating wheel 232 clamp or release the lens.

[0044] Specifically, the pneumatic element 21 includes a cylinder, a pneumatic motor, a pneumatic valve, etc., which can convert electrical energy into mechanical energy and drive the first cantilever 22 and the second cantilever 23 to move in the horizontal direction by controlling the flow of gas. When the air pressure in the cylinder increases, the first cantilever 22 and the second cantilever 23 move in the specified direction; conversely, when the air pressure decreases, the first cantilever 22 and the second cantilever 23 move in the opposite direction. The pneumatic element 21 controls the movement of the first cantilever 22 and the second cantilever 23 in the horizontal direction, can accurately control the position and direction of the manipulator, improve production efficiency, reduce labor intensity, and also reduce pollution to the environment.

[0045] Furthermore, the first focusing module also includes a first driving motor 221, and the second focusing module also includes a second driving motor 231. The first driving motor 221 and the second driving motor 231 are respectively used to drive the first rotating wheel disc 222 and the second rotating wheel disc 232 to rotate. Specifically, according to the load and rotation speed requirements of the first rotating wheel disc 222 and the second rotating wheel disc 232, appropriate motor types and specifications are selected, such as stepping motors or DC motors, and the output shafts of the first driving motor 221 and the second driving motor 231 are respectively connected to the first rotating wheel disc 222 and the second rotating wheel disc 232. For the method of connecting the first driving motor 221 and the second driving motor 231 and the first rotating wheel disc 222 and the second rotating wheel disc 232, an appropriate connection method can be selected according to specific needs, such as using bearings, couplings, gear transmission, etc.

[0046] Further, the first driving motor 221 is located at the top of the end of the first cantilever 22, the first rotating wheel disc 222 is located at the bottom of the end of the first cantilever 22, and the first driving motor 221 and the first rotating wheel disc 222 are connected by a synchronous belt;

[0047] The second driving motor 231 is located at the top of the end of the second cantilever 23 , the second rotating wheel 232 is located at the bottom of the end of the second cantilever 23 , and the second driving motor 231 is connected to the second rotating wheel 232 via a synchronous belt.

[0048] For example, in the embodiment of the present disclosure, the first drive motor 221 and the second drive motor 231 are stepper motors, and two sets of stepper motors are respectively installed at the top of the ends of the first cantilever 22 and the second cantilever 23. The first cantilever 22 and the second cantilever 23 should be fixed structures that can stabilize the stepper motors and provide installation positions. Rotating wheel brackets are respectively provided at the bottom of the ends of the first cantilever 22 and the second cantilever 23, and the first rotating wheel 222 and the second rotating wheel 232 are respectively installed below the rotating wheel brackets, and ensure that the first rotating wheel 222 and the second rotating wheel 232 are respectively connected to the output shafts of the stepper motors.

[0049] In the disclosed embodiment, the edges of the first rotating wheel 222 and the second rotating wheel 232 are inlaid with rubber belts, which can increase friction, improve clamping strength and stability. This is because rubber itself has good elasticity and toughness, can deform when subjected to force, and then return to its original shape after the force is released, so that the rubber belt can form a close contact between the lens and the first rotating wheel 222 and the second rotating wheel 232, thereby increasing friction. On the other hand, rubber itself is an insulator and is not easy to conduct electricity, so the heat generated during the friction process is not easy to conduct through the rubber, thereby reducing the risk of damage to the lens due to overheating.

[0050] In a more preferred embodiment, the camera focusing mechanism further includes a lifting component 3, the lifting component 3 includes a lifting platform 31, the bottom of the pneumatic element 21 is fixedly connected to the lifting platform 31, and the lifting component 3 is used to control the movement of the focusing component 2 in the vertical direction. In the disclosed embodiment, the lifting component 3 is a slide cylinder, and the focusing component 2 is installed on the slide cylinder. The lifting component 3 enables the focusing component 2 to move up and down, meeting the needs of different cameras and having good compatibility. In some embodiments, a lifting speed control valve is provided on the slide cylinder to control the speed of the lifting movement of the focusing component 2.

[0051] In the disclosed embodiment, a camera image controller 12 is also provided on the workbench 1, and the camera image controller 12 is located at the top of the workbench 1 and at the bottom of the camera fixture 11. The camera image controller 12 includes a camera interface and a control interface, wherein the camera interface is responsible for transmitting image data, and the control interface is responsible for transmitting control information, and controls the first rotating wheel 222 and the second rotating wheel 232 to rotate by clamping and driving the adjusting outer ring 41 according to the optical image generated by the camera 4 to be focused through the lens, until the optical image is optimal, at which time the focusing is completed.

[0052] In the embodiment of the present disclosure, the pneumatic element 21 uses a finger cylinder, and the first cantilever 22 and the second cantilever 23 are connected to a sliding bearing or a linear guide to ensure that they can move smoothly. The sliding bearing or linear guide is fixed to the bracket at the top of the finger cylinder or fixed to the finger cylinder through an appropriate supporting device. It should be noted that the connection between the first cantilever 22 and the second cantilever 23 and the sliding bearing or linear guide should be ensured to be stable and reliable. It can be understood that an appropriate air control system is required to control the movement of the finger cylinder, which can be achieved by controlling the switch of the air source through an electromagnetic valve, or by using a pneumatic control system. The control logic is designed according to the needs to control the telescopic movement and stop position of the finger cylinder to achieve the clamping and release of the camera to be focused by the first cantilever 22 and the second cantilever 23. Further, in the embodiment of the present disclosure, a horizontal speed control valve is provided on the finger cylinder, and the horizontal speed control valve can be provided on the air inlet or exhaust port of the cylinder. By adjusting the opening size of the horizontal speed control valve, the air intake or exhaust speed of the finger cylinder can be changed, thereby realizing the speed control of the movement of the finger cylinder, and then controlling the speed of the horizontal movement of the first cantilever 22 and the second cantilever 23. In addition, in other embodiments, a throttle valve, a speed regulating motor or a controller can be used to control the speed of the finger cylinder. Different applications and scenarios may choose different speed control methods, and the specific control method can be selected according to the requirements of the equipment and the design of the system. In a more preferred embodiment, in order to ensure the safety of operation, safety protection measures such as limit switches, sensors, etc. can be added during the operation to avoid accidental pinching or other dangerous situations.

[0053] Furthermore, the embodiment of the present disclosure further includes a control unit, which is used to control the first focusing module and the second focusing module to focus the camera 4 to be focused according to a preset program.
