[0048] In addition, for a better illustration of the present application, numerous specific details are given in the following detailed description. Those skilled in the art should understand that the present application can be implemented without some of these specific details. In some instances, methods, means, elements, and circuits well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0049] As Figures 1 - 5 shown, the industrial camera with a movable internal imaging component according to an embodiment of the present application includes: a housing 100, a lens barrel, a moving component, and a circuit board component. The housing 100 has an open bottom and a hollow interior. The lens barrel is disposed inside the housing 100. Among them, the lens barrel includes a second lens barrel 120 and a first lens barrel 110. The second lens barrel 120 and the first lens barrel 110 are sequentially arranged along the opening direction of the housing 100. The first lens barrel 110 is adjacent to the open end of the housing 100. The moving component is disposed inside the housing 100 and is respectively connected to the housing 100 and the first lens barrel 110 to adjust the positions of the second lens barrel 120 and the first lens barrel 110 relative to the housing 100. The circuit board component is disposed at the top inside the housing 100, has a preset distance from the lens barrel, and is respectively electrically connected to the moving component and the lens barrel to control the opening and closing of the moving component and the imaging of the lens barrel.

[0050] In this specific embodiment, a traditional industrial camera needs to manually rotate the lens or replace the lens to achieve zooming or focusing. In the present application, the first lens barrel 110 is driven to move up and down by an internal moving component, without the need to disassemble the housing 100 or the lens, greatly improving the use efficiency. Specifically, two sets of motors are added as power components inside the housing 100 of the industrial camera and are connected to the second lens barrel 120 and the first lens barrel 110. Among them, the output end of the zoom motor 421 meshes with the lens barrel gear of the first lens barrel 110 to drive the first lens barrel 110 to rotate. When the lens barrel rotates, the internal lens moves up and down as the lens barrel rotates, thereby achieving camera zooming. The motor guide rail 415 and the upper and lower sliders 414 drive the first lens barrel 110 and the second lens barrel 120 to move up and down, thereby achieving camera focusing, so as to achieve the purpose of simplifying the structure, improving the efficiency, and enhancing the durability and portability of the product.

[0051] In a specific embodiment, it further includes a main connecting member 430. The main connecting member 430 is a plate-like structure with an annular cross-section and is sleeved outside the second lens barrel 120 for fixed connection. The main connecting member 430 is used for connecting the second lens barrel 120 and the first lens barrel 110. Among them, the main connecting member 430 is a plate-like structure with an annular cross-section, so that when the main connecting member 430 moves up and down relative to the housing 100, the first lens barrel 110 and the second lens barrel 120 can also move up and down relative to the housing 100.

[0052] In this specific embodiment, the moving assembly includes a zoom assembly and a magnification changing assembly. The zoom assembly is arranged on the side wall inside the housing 100 to adjust the relative positions of the second lens barrel 120 and the first lens barrel 110 relative to the housing 100. The magnification changing assembly 420 is arranged on the main connecting member 430 to adjust the magnification of the first lens barrel 110. Among them, the zoom assembly is used to control the distance between the second lens barrel 120 and the first lens barrel 110 relative to the circuit board assembly, and the magnification changing assembly 420 is used to control the movement of the lenses inside the lens barrel. The zoom assembly and the magnification changing assembly 420 are independently controlled and support "zooming first and then changing magnification" or "synchronous adjustment". The main connecting member 430 serves as a mechanical interface to integrate the first lens barrel 110 with the zoom assembly and the magnification changing assembly 420, reducing the number of parts and improving reliability. The independent settings of the zoom and magnification changing functions make the camera more flexible and accurate when adjusting imaging parameters. Users can adjust the zoom and magnification respectively according to actual shooting needs to obtain the best shooting effect. For example, in industrial inspection, for some products with complex shapes and large size differences, through independent zoom and magnification adjustment, various details of the products can be clearly observed, improving the accuracy of inspection.

[0053] In a specific embodiment, the zoom component includes: an up-and-down motor 413, a guide rail 415, a motor gear, and a slider 414. The relative movement of the first lens barrel 110 and the second lens barrel 120 in the opening direction of the housing 100 is completed through the zoom component, and the zoom of the camera is achieved by adjusting the distance. Specifically, the up-and-down motor 413 is fixedly arranged in the housing 100 and is communicatively connected to the circuit board assembly. The circuit board assembly can send control signals to the up-and-down motor 413 to control the start, stop, and rotation speed of the motor. The motor serves as a power source and provides power support for the movement of the zoom component. The guide rail 415 is a threaded rod, one end of which is connected to the output end of the up-and-down motor 413. When the up-and-down motor 413 starts, it will drive the guide rail 415 to rotate, and the rotational movement of the motor can be converted into a linear movement. The motor gear is sleeved on the other end of the guide rail 415, and the motor gear is provided with external threads, while the slider 414 is provided with internal threads. The slider 414 is fixedly arranged on the main connecting member 430 and is threadedly connected to the motor gear. When the guide rail 415 rotates, the motor gear will also rotate accordingly. Since the slider 414 is threadedly connected to the motor gear, the slider 414 will move up and down along the guide rail 415. And the slider 414 is fixed on the main connecting member 430, and the main connecting member 430 is connected to the first lens barrel 110. Therefore, the up-and-down movement of the slider 414 will drive the first lens barrel 110 and the second lens barrel 120 to move up and down relative to the housing 100, extending out of the housing 100 or retracting into the housing 100, thereby realizing the zoom function. By means of the transmission of the threaded rod and the gear slider 414, it has high transmission accuracy and stability. Compared with other transmission methods, such as belt transmission or chain transmission, the threaded rod transmission can more accurately control the moving distance of the first lens barrel 110, thus ensuring the accuracy of zooming. At the same time, the reliability of the screw transmission method is relatively high, and it can maintain stable performance during long-term use and reduce the occurrence of failures. For example, on an industrial automation production line, the camera needs to perform zoom operations frequently. This high-precision and high-stability transmission method can ensure that the camera can always accurately obtain the required images, improving production efficiency and product quality.

[0054] In a specific embodiment, the zoom component further includes: a mounting bracket 411. The mounting bracket 411 is fixedly arranged in the housing 100, and the up-and-down motor 413 is arranged on the mounting bracket 411. The mounting bracket 411 is used for mounting the up-and-down motor 413 and fixing it on the side wall inside the housing 100.

[0055] In this specific embodiment, the mounting bracket 411 is a plate-like structure. Threaded holes are formed on the plate surface of the mounting bracket 411 and are bolted to the housing 100. By means of bolt connection, the mounting bracket 411 can be firmly fixed inside the housing 100, avoiding loosening or displacement during the operation of the camera. At the same time, this connection method is also convenient for installation and disassembly, facilitating the maintenance and replacement of the motor.

[0056] Further, in this specific embodiment, the mounting bracket 411 further includes a mounting plate which is arranged at one end of the mounting bracket 411 in the length direction. The up-and-down motor 413 is arranged on the mounting plate, and the output shaft of the up-and-down motor 413 passes through the mounting plate and is connected to the guide rail 415. The mounting plate provides a stable mounting platform for the motor, ensuring that the output shaft of the motor can be accurately connected to the guide rail 415 and guaranteeing the accuracy of transmission. In addition, the mounting plate is in a plate-like structure and has a platform for placing the up-and-down motor 413 for mounting and fixing. By fixing the mounting bracket 411 to the housing 100 instead of directly fixing the up-and-down motor 413 to the housing 100, the up-and-down motor 413 can be prevented from being damaged by force.

[0057] In a specific embodiment, the zoom component 420 includes a zoom motor 421 and a lens gear 422. The zoom motor 421 is arranged on the main connecting member 430. The lens gear 422 is sleeved outside the first lens barrel 110 and fixedly connected. The output end of the zoom motor 421 is connected to the lens gear 422 to control the circumferential rotation of the first lens barrel 110 and drive the lens inside the first lens barrel 110 to move up and down. A motor gear is arranged at the output end of the zoom motor 421 and meshes with the lens gear 422 sleeved outside the first lens barrel 110. The first lens barrel 110 can rotate when the motor is turned on, and the lens inside the first lens barrel 110 moves up and down as the lens barrel rotates. The imaging magnification changes as the lens moves, thereby realizing imaging zoom.

[0058] In this specific embodiment, the zoom motor is arranged on the main connecting member 430, and the main connecting member 430 provides a fixed mounting position for the zoom motor, ensuring the stability of the motor during operation. The zoom motor 421, as the power source of the zoom component 420, can provide precise power output to control the zoom of the first lens barrel 110. The lens gear 422 is sleeved outside the first lens barrel 110 and fixedly connected, and the output end of the zoom motor 421 is connected to the lens gear 422. When the zoom motor 421 starts, it will drive the lens gear 422 to rotate. Since the lens gear 422 is fixedly connected to the first lens barrel 110, the rotation of the lens gear 422 will drive the circumferential rotation of the first lens barrel 110. Usually, a special thread structure or transmission mechanism is arranged inside the first lens barrel 110. When the first lens barrel 110 rotates circumferentially, it will drive the lens inside to move up and down, thereby realizing the zoom function.

[0059] This method of controlling the movement of the lens in the first lens barrel 110 by driving the lens gear 422 by a motor has high precision and flexibility. The zoom motor can accurately control the rotation angle and speed of the lens gear 422 according to the control signal sent by the circuit board assembly, thereby realizing accurate control of the moving distance and speed of the lens. For example, when shooting objects at different distances, the camera can automatically adjust the operating parameters of the zoom motor according to the distance of the object, so that the lens can be quickly and accurately moved to the appropriate position to obtain a clear image. At the same time, this zoom method can also achieve continuous zooming to meet the needs of different shooting scenes. In industrial detection, for some scenes where objects of different depths need to be observed, the continuous zoom function can help detection personnel observe the internal structure and details of the object more clearly, and improve the accuracy of detection.

[0060] In a specific embodiment, it also includes: an optical rod 510 and an optical rod fixing block 520, which ensure that the main connecting member 430 can move along the opening direction of the shell 100, and the length direction of the main connecting member 430 is the same as the direction of the lens barrel, which has a guiding and stabilizing effect.

[0061] In this specific embodiment, the fixed block is a cubic structure, fixedly arranged on the main connecting member 430, and the main connecting member 430 is connected to the first lens barrel 110, so the optical rod fixed block 520 also moves with the movement of the first lens barrel 110. The optical rod 510 is a rod-shaped structure with a preset length, arranged along the opening direction of the housing 100, one end of which is fixedly connected to the fixed block, and the other end passes through the top of the housing 100. When the first lens barrel 110 moves up and down under the drive of the moving assembly, the optical rod fixed block 520 will slide along the optical rod 510, ensuring that the first lens barrel 110 can only move along the direction of the optical rod 510, avoiding lateral deviation or shaking, making the movement of the first lens barrel 110 more stable and accurate, thereby ensuring the quality of imaging. The optical rod 510 can also enhance the stability of the camera structure. The connection between the optical rod 510 and the top of the housing 100 and the optical rod fixed block 520 forms a stable support structure. In an industrial environment, the camera may be affected by various factors, such as machine vibration, air flow disturbance, etc. The presence of the optical rod 510 can reduce the interference of these factors on the movement of the first lens barrel 110, ensuring that the camera can work normally in a complex environment. For example, in some high-speed industrial production lines, the camera needs to quickly and accurately adjust the position of the lens barrel to obtain an image. The guiding and stabilizing effect of the optical rod 510 can ensure that the camera can still provide clear and stable images in this case, thereby improving production efficiency and product quality.

[0062] In a specific embodiment, it further includes: a fixing frame 700. The fixing frame 700 is an annular structure with a height, sleeved outside the first lens barrel 110, and the main connecting member 430 is fixedly connected to the fixing frame. They are all located at the connection position of the first lens barrel 110 and the second lens barrel 120. One side of the fixing frame 700 is fixedly connected to the end of the second lens barrel 120, and the other is fixedly connected to the main connecting member 430. The fixing frame 700 can firmly connect the second lens barrel 120 and the first lens barrel 110 together, enhancing the stability of the camera structure. At the same time, the fixing frame 700 also provides an accurate positioning reference for the first lens barrel 110 and the zoom component, ensuring their accurate positions inside the camera.

[0063] In this specific embodiment, one end of the first lens barrel 110 sleeved with the lens gear 422 extends into the interior of the fixing frame 700, and the output end of the zoom motor 421 extends into the interior of the fixing frame 700 and meshes with the lens gear 422. The internal space of the fixing frame 700 provides a relatively enclosed environment for the lens gear 422 and the output end of the zoom motor, which can effectively protect them from the intrusion of external dust and debris. In an industrial environment, dust and debris may affect the meshing of the gears, resulting in a decrease in transmission accuracy or malfunctions. The protective effect of the fixing frame 700 can reduce the occurrence of these problems and extend the service life of the camera. In addition, the fixing frame 700 can also enhance the transmission stability of the zoom component, effectively constraining the lens gear 422 and the output end of the zoom motor, making the transmission process more stable and reducing the generation of vibration and noise. For example, during the zoom operation, the fixing frame 700 can ensure that the lens gear 422 and the output end of the zoom motor always maintain a good meshing state, achieving precise zoom control and improving the imaging quality.

[0064] In a specific embodiment, it further includes a limit switch 412 and a limiting portion. The limiting portion is the main structure and is vertically arranged on the main connecting member 430. The limit switch 412 is arranged on the upper and lower motor 413 or the mounting plate, and the limit switch 412 and the limiting portion are arranged vertically. The limit switch 412 is a touch switch and is connected to the circuit board assembly. When the zoom component 420 of the camera starts to work, the upper and lower motor 413 drives the guide rail 415 to rotate, thereby driving the slider 414 and the main connecting member 430 to move. The limiting portion will also move accordingly. When the limiting portion moves to a certain position along with the main connecting member 430 and abuts against the limit switch 412, the limit switch 412 will be triggered. Since the limit switch 412 is connected to the circuit board assembly, it will immediately transmit this trigger signal to the circuit board assembly. After receiving the signal, the circuit board assembly will make corresponding responses according to the preset program. The limit switch 412 can control the upper and lower motor 413 to stop working, so as to avoid the first lens barrel 110 from continuing to move, prevent the lens barrel from exceeding its reasonable moving range, and thus protect the internal structure of the camera from being damaged. On the other hand, the circuit board assembly can also control the main connecting member 430 to move in a direction away from the limit switch 412, which is equivalent to automatically adjusting the position of the lens barrel to make it return to the safe working range.

[0065] In this specific embodiment, when the industrial camera performs a zoom operation, the first lens barrel 110 will move up and down under the drive of the moving component. Without a limiting device, the first lens barrel 110 may move excessively, resulting in collisions or squeezes with other components inside the camera, thereby damaging the structure of the camera. For example, the lens barrel may hit the top or bottom of the housing 100, causing problems such as lens breakage and lens barrel deformation. The setting of the limit switch 412 and the limiting portion can stop the motor in time when the lens barrel moves to the limit position, avoiding this situation and effectively protecting the internal structure of the camera, and prolonging the service life of the camera. If the lens barrel exceeds the reasonable range during the movement, it may cause a decrease in imaging quality and affect the accuracy of the detection result. The limit switch 412 and the limiting portion can ensure that the lens barrel always moves within a safe range, ensuring the stability and consistency of the camera imaging. For example, when performing an appearance inspection on industrial products, stable imaging can enable the detection system to more accurately identify product defects and improve the reliability of the detection. The connection between the limit switch 412 and the circuit board assembly enables the camera to achieve automatic position control. After the limiting portion triggers the limit switch 412, the circuit board assembly can automatically control the start and stop of the motor and the moving direction of the main connecting member 430 without manual intervention. This not only improves the convenience of operation but also reduces the influence of human factors on the camera operation and improves the use efficiency.

[0066] In a specific embodiment, it further includes a display screen 600. The display screen 600 is embedded outside the housing 100. The circuit board assembly includes: a main board 310, a front circuit board 330, a screen circuit board 340, and an interface board. The main board 310 is connected to the front circuit board 330, the screen circuit board 340, and the interface board. The front circuit board 330 and the interface board are connected to the second lens barrel 120 to obtain the imaging of the lens barrel. The screen circuit board 340 is fixedly arranged inside the housing 100 and is connected to the display screen 600 to display the imaging of the lens barrel. Users can directly observe the images captured by the camera through the display screen 600 without the need to additionally connect an external display device, which greatly improves the convenience of using the camera. For example, when performing inspections at an industrial site, operators can directly view the images on the camera, promptly discover problems, and handle them.

[0067] In this specific embodiment, the circuit board assembly includes a main board 310, a front circuit board 330, a screen circuit board 340, and an interface board 320. The main board 310, as the core of the entire circuit board assembly, is connected to the front circuit board 330, the screen circuit board 340, and the interface board 320, responsible for coordinating the work of each circuit board and controlling and managing various functions of the camera. The front circuit board 330 and the interface board 320 are connected to the second lens barrel 120 and are arranged at the top position inside the housing 100. By having a preset distance from the second lens barrel 120, the imaging signal of the lens barrel is obtained. The image signal collected by the lens barrel is transmitted to the main board 310 through the front circuit board 330 and the interface board 320 for processing. The screen circuit board 340 is fixedly arranged inside the housing 100 and is connected to the display screen 600. It converts the image signal processed by the main board 310 into a signal that the display screen 600 can display, driving the display screen 600 to display the imaging of the lens barrel.
