Abstract
Description
Technical Field
[0001] This utility model relates to the field of camera technology, specifically to an optical character dustproof recognition smart camera. Background Technology
[0002] Character recognition in industrial environments faces numerous limitations and challenges, primarily including five aspects: diverse objects, environmental noise, rapid object movement, large data volume, and security. Optical character recognition refers to the process by which electronic devices, such as scanners or digital cameras, examine characters printed on paper, determine their shape by detecting dark and light patterns, and then translate the shape into computer text using character recognition methods.
[0003] For example, announcement number CN101738828B (named "A CCD High-Definition Intelligent Industrial Camera") includes a camera device and a set of demonstration software. The demonstration software runs on a PC and controls the operation of the camera device. The camera device includes a digital signal processor, a memory chip, a program memory, a power management module, a network physical layer chip, a serial expansion chip, a front-end optocoupler, an analog front-end board, a programmable logic device (PLD), and a data address buffer. The front-end optocoupler is mainly used to sense external image information. Its output is connected to the input of the analog front-end board, transmitting the sensed external image information to the analog front-end board. The output of the analog front-end board is connected to the input of the PLD. The analog front-end board converts the signal output from the front-end optocoupler into a digital signal and transmits the digital signal to the PLD. The PLD generates the control timing for the front-end optocoupler to perform integration operations, and simultaneously converts the data input from the analog front-end board and inputs it to the data address buffer.
[0004] The aforementioned smart camera lacks an effective dustproof mechanism for the camera body during optical character recognition, which makes the lens part easily covered by dust during installation and use, resulting in poor accuracy of optical character recognition. To address this, we provide a dustproof optical character recognition smart camera. Utility Model Content
[0005] The purpose of this utility model is to provide an optical character dustproof smart camera to solve the problem mentioned in the background art that existing smart cameras lack an effective dustproof mechanism for the camera body during optical character recognition, which makes the lens part of the smart camera easily covered by dust during installation and use, resulting in poor accuracy of optical character recognition.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an optical character dustproof recognition smart camera, including a camera base plate, a camera body placed on the upper end of the camera base plate, a sleeve frame sleeved on the outside of the camera body, and support plates welded on both outer walls of the sleeve frame, both support plates being integral with the camera base plate.
[0007] Also includes:
[0008] The movable cavity is located inside the camera base plate, and a first lens frame and a second lens frame are provided inside the movable cavity. A central circular groove is provided at the center of the camera base plate, and the central circular groove is connected to the interior of the movable cavity.
[0009] A perforated block is provided on one side of the camera base plate, and a push rod is provided inside the perforated block;
[0010] Positioning screw holes are provided on the outer walls of both sides of the first lens frame and the second lens frame, and positioning screws are provided at the connection position between the first lens frame and the camera mount plate.
[0011] Preferably, a bearing seat is integrally formed on one side of the outer wall of the camera base plate, and a mounting rod is rotatably mounted on the outside of the bearing seat. One end of the mounting rod is welded to the perforated block.
[0012] Preferably, the bearing housing has two assembly holes on one side, both of which are integral with the camera base plate. Each assembly hole is equipped with a locking screw, and both locking screws abut against the mounting rod.
[0013] Preferably, a threaded sleeve is integrally formed on the outer wall of one of the support plates, and a threaded connecting rod is movably arranged inside the threaded sleeve. A mounting end is welded to one end of the threaded connecting rod.
[0014] Preferably, the first lens frame and the second lens frame are fixedly connected to the center position of the camera mount plate by positioning screws, and the first lens frame and the second lens frame are of equal size.
[0015] Preferably, one end of the push rod is integrally formed with a magnetic block, and the push rod is attracted and connected to the first lens frame and the second lens frame through the magnetic block.
[0016] Preferably, the internal lens dimensions of the first lens frame and the second lens frame are equal to the dimensions of the central circular groove and the lens dimensions of the camera body.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This invention protects the lens structure of the camera body by using a first lens frame to shield it. Dust will only contaminate the circular lens inside the first lens frame, and since the circular lens is positioned downwards, the attached dust will fall off naturally, reducing the density of dust accumulation. When the first lens frame is heavily contaminated by dust, the positioning screw can be removed, and then the second lens frame can be pushed. This will cause the first lens frame to be pushed out of the movable cavity, and the second lens frame will reach the position of the central circular groove. Thus, the lens part of the intelligent industrial camera is re-protected from dust by the second lens frame. This overcomes the problem that existing intelligent cameras lack an effective dust protection mechanism for the camera body during optical character recognition, which makes the lens part of the intelligent camera easily covered by dust during installation and use, resulting in poor accuracy of optical character recognition.

[0030] The camera body 2 is an intelligent industrial camera used for optical character recognition. During use, rotating the threaded connecting rod 7 drives the threaded sleeve 6 to guide and adjust its position, thereby adjusting the mounting base 8 to the appropriate mounting position. It is then positioned using mounting screws. When the intelligent industrial camera performs optical character recognition, the lens structure of the camera body 2 is protected by the first lens frame 12. Dust will only contaminate the circular lens within the first lens frame 12, and since the circular lens is positioned downwards, the attached dust will naturally fall off, reducing the density of dust accumulation. When the first lens frame 12... 2. After being heavily contaminated by dust, remove the positioning screw 9, and then push the second lens frame 15. This will cause the first lens frame 12 to be pushed out of the movable cavity 13, and the second lens frame 15 to reach the position of the central circular groove 11. Thus, the lens part of the intelligent industrial camera is re-protected from dust through the second lens frame 15. After the first lens frame 12 is cleaned, it is put back into the movable cavity 13 for the next replacement.
