[0002] Industrial cameras are a key component in machine vision systems. Their most essential function is to convert light signals into ordered electrical signals.

[0003] At present, industrial cameras are mostly used in industrial production and cargo classification, and the operating environment is mostly dusty. Long-term use may cause the lens to be contaminated by dust, resulting in reduced shooting effects. Therefore, the lens part of the industrial camera needs to be cleaned regularly.

[0004] In the existing technology, the cleaning of the lens parts of industrial cameras mostly relies on manual wiping of the camera lens. However, manual wiping of the camera lens is relatively inefficient on the one hand, and on the other hand, since some industrial cameras are installed too high, manual wiping of the camera lens requires climbing to the height of the industrial camera with the help of climbing tools, which poses certain safety hazards.

DETAILED DESCRIPTION

[0031] The technical solution of the present application will be further described in detail below in conjunction with specific implementation methods.

[0032] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0033] See also Figure 1 、 Figure 2 and Figure 4 This embodiment provides a self-cleaning industrial camera, including a camera body 10, a protective sleeve 20, a driving assembly 40, an elastic rope 50 and a traction assembly 60. The protective sleeve 20 is sleeved on the outside of the camera body 10, and the traction assembly 60 is slidably arranged on the inner wall of the protective sleeve 20. One end of the elastic rope 50 is connected to the top inner side of the protective sleeve 20, and the other end is connected to the traction assembly 60. The driving assembly 40 is installed on the upper part of the protective sleeve 20, and is used to drive the traction assembly 60 to slide back and forth along the inner wall of the protective sleeve 20, so as to drive the elastic rope 50 to move in contact with the side of the lens of the camera body 10.

[0034] Initially, the traction assembly 60 is located at the upper left corner of the inner wall of the protective sleeve 20, so that the elastic rope 50 is located between the protective sleeve 20 and the camera body 10 and remains in a tilted left state. At this time, the elastic rope 50 will not block the normal shooting operation of the camera body 10. When the lens of the camera body 10 needs to be cleaned, the traction assembly 60 can be driven by the driving assembly 40 to slide counterclockwise along the inner wall of the protective sleeve 20. When the traction assembly 60 slides counterclockwise, one end of the elastic rope 50 can be pulled to move along a counterclockwise trajectory until the traction assembly 60 slides to the upper right corner of the inner wall of the protective sleeve 20, at which time the elastic rope 50 is detached from the lens side of the camera body 10 and is in a tilted right state. In the above process, the elastic rope 50 The rope 50 can be adaptively extended and retracted, and at the same time, the elastic rope 50 moves in contact with the side of the lens of the camera body 10 during movement, thereby scraping off dust and debris on the side of the lens of the camera body 10, thereby realizing automatic cleaning of the lens of the camera body 10; after the camera body 10 has been working for a certain period of time, the driving assembly 40 can drive the traction assembly 60 to slide clockwise along the inner wall of the protective sleeve 20, and when the traction assembly 60 slides clockwise, it can pull one end of the elastic rope 50 to move along a clockwise trajectory until the traction assembly 60 slides to the upper left corner of the inner wall of the protective sleeve 20 again, the elastic rope 50 detaches from the side of the lens of the camera body 10 and is in a tilted state to the left, thereby realizing automatic cleaning of the lens of the camera body 10 again.

[0035] See also Figure 1 and Figure 4In one embodiment, the inner wall of the protective sleeve 20 is fixedly provided with a first annular guide rail 201, the traction assembly 60 includes a second slider 601 and an extension rod 602, the second slider 601 is slidably matched with the first annular guide rail 201, the extension rod 602 is fixedly provided on one side of the second slider 601, the end of the elastic rope 50 away from the inner top wall of the protective sleeve 20 is connected to the second slider 601, the driving assembly 40 includes a support 401, a winding roller 402, a first rope body 403, a second rope body 404 and Motor 405, the support 401 is fixedly mounted on the outer top wall of the protective sleeve 20, the motor 405 is fixedly arranged on one side of the support 401, the winding roller 402 is installed at the output end of the motor 405, one end of the first rope body 403 and the second rope body 404 are respectively wound around the outside of the winding roller 402, and the other end extends to the inside of the protective sleeve 20 and is respectively connected to the opposite sides of the extension rod 602, and the first rope body 403 and the second rope body 404 are wound in opposite directions outside the winding roller 402.

[0036] When the lens of the camera body 10 needs to be cleaned, the motor 405 drives the winding roller 402 to rotate. Since the first rope body 403 and the second rope body 404 are wound in opposite directions outside the winding roller 402, when the winding roller 402 rotates, the first rope body 403 can be unwound and the second rope body 404 can be wound. During the winding process of the second rope body 404, the extension rod 602 can be pulled, thereby driving the second slider 601 to slide counterclockwise along the first annular guide rail 201, thereby pulling one end of the elastic rope 50 to move along the counterclockwise trajectory until the second slider 601 slides from the upper left corner position of the inner wall of the protective sleeve 20 to the upper right corner position, and the elastic rope 50 slides against the side surface of the lens of the camera body 10 to scrape off the dust and debris on the side surface of the lens of the camera body 10, thereby achieving the desired effect. Automatic cleaning of the lens of the camera body 10; after the camera body 10 has been working for a period of time, when the lens of the camera body 10 needs to be cleaned, the motor 405 drives the winding roller 402 to rotate in the opposite direction, thereby reeling in the first rope body 403 and unreeling the second rope body 404. During the reeling process of the first rope body 403, the extension rod 602 can be pulled, thereby driving the second slider 601 to slide clockwise along the first annular guide rail 201, thereby pulling one end of the elastic rope 50 to move along a clockwise trajectory until the second slider 601 slides from the upper right corner position of the inner wall of the protective sleeve 20 to the upper left corner position, and the elastic rope 50 slides in the opposite direction against the side surface of the lens of the camera body 10 to scrape off dust and debris on the side surface of the lens of the camera body 10, thereby realizing automatic cleaning of the lens of the camera body 10 again.

[0037] See also Figure 1 and Figure 4In one embodiment, a limiting ring plate 202 is fixedly provided on the inner wall of the protective sleeve 20, and the vertical cross-section of the limiting ring plate 202 is an L-shaped structure. The end of the extension rod 602 away from the second slider 601 extends to the inner side of the limiting ring plate 202, and the ends of the first rope body 403 and the second rope body 404 away from the winding roller 402 are passed through the inner side of the limiting ring plate 202 and are respectively connected to the opposite sides of the extension rod 602.

[0038] By setting the limiting ring plate 202, the first rope body 403 and the second rope body 404 can be limited to a ring structure, so that the first rope body 403 and the second rope body 404 can move along the ring track when winding, thereby better pulling the second slider 601 to slide along the ring track.

[0039] See also Figure 1 In one embodiment, a cleaning assembly 30 is further provided between the protective sleeve 20 and the camera body 10. After the elastic rope 50 has finished scraping off dust and debris on the lens of the camera body 10, the cleaning assembly 30 is used to clean the dust and debris attached to the elastic rope 50, thereby improving the subsequent scraping effect of the elastic rope 50 on dust and debris on the side of the lens of the camera body 10.

[0040] See also Figure 3 and Figure 4 In one embodiment, the cleaning assembly 30 includes a cleaning roller 301 , the cleaning roller 301 is attached to the outer wall of the camera body 10 , and the elastic rope 50 passes through the cleaning roller 301 and movably cooperates with the cleaning roller 301 .

[0041] When the second rope body 404 is wound to pull the second slider 601 from the upper left corner of the inner wall of the protective sleeve 20 to the lowermost position, the elastic rope 50 applies a force to the cleaning roller 301 in the direction of the camera body 10. Under the action of this force, the cleaning roller 301 can be driven to slide upward in contact with the camera body 10. When the second slider 601 passes the lowermost position of the protective sleeve 20 and slides to the upper right corner position, the cleaning roller 301 passes the uppermost position of the camera body 10 and slides toward the upper right corner position of the inner side of the protective sleeve 20. When the second slider 601 slides to the upper right corner position of the inner wall of the protective sleeve 20, the elastic rope 50 is detached from the lens side of the camera body 10, and the cleaning roller 301 moves to the upper right corner position of the inner wall of the protective sleeve 20. At this time, the elastic rope 50 contracts and moves relative to the cleaning roller 301. The cleaning roller 301 can be used to scrape off dust and debris attached to the elastic rope 50, thereby realizing automatic cleaning of the elastic rope 50. Logic is, in the process that the first rope body 403 is wound up to pull the second slider 601 to slide down from the upper right corner position of the inner wall of the protective sleeve 20 to the lowest position, the elastic rope 50 applies a force toward the camera body 10 to the cleaning roller 301. Under the action of this force, the cleaning roller 301 can be driven to slide upward in contact with the camera body 10. When the second slider 601 passes the lowest position of the protective sleeve 20 and slides to the upper left corner position, the cleaning roller 301 passes the uppermost position of the camera body 10 and slides toward the upper left corner position on the inner side of the protective sleeve 20. When the second slider 601 slides to the upper left corner position of the inner wall of the protective sleeve 20, the elastic rope 50 is detached from the lens side of the camera body 10. At the same time, the cleaning roller 301 moves to the upper left corner position of the inner wall of the protective sleeve 20. At this time, the elastic rope 50 contracts and moves relative to the cleaning roller 301. The cleaning roller 301 can be used to scrape off dust and debris attached to the elastic rope 50, thereby realizing automatic cleaning of the elastic rope 50.

[0042] See also Figure 3 and Figure 4 In one embodiment, a second annular guide rail 203 is fixedly provided on the inner wall of the protective sleeve 20 , and a first slider 302 is rotatably provided on one end of the cleaning roller 301 , and the first slider 302 is slidably engaged with the second annular guide rail 203 .

[0043] In one embodiment, the cleaning roller 301 is hollow and contains cleaning liquid.

[0044] As the second slider 601 pulls the elastic cord 50 to slide back and forth along the first annular guide rail 201, the elastic cord 50 can adaptively expand and contract relative to the cleaning roller 301. Since the elastic cord 50 passes through the cleaning roller 301, during the expansion and contraction of the elastic cord 50 relative to the cleaning roller 301, the cleaning liquid inside the cleaning roller 301 can act on the elastic cord 50 and be carried out by the elastic cord 50, thereby acting on the side surface of the lens of the camera body 10 together with the elastic cord 50, thereby improving the cleaning effect of the lens of the camera body 10. In addition, when the elastic cord 50 does not need to clean the lens of the camera body 10, the elastic cord 50 is arranged at an angle between the camera body 10 and the protective sleeve 20, that is, the elastic cord 50 passes through the cleaning roller 301 at an angle. At this time, the two sets of holes on the cleaning roller 301 for the elastic cord 50 to pass through are also arranged at an angle, so that the two sets of holes can be located above the liquid level of the cleaning liquid inside the cleaning roller 301, thereby preventing leakage of the cleaning liquid.

[0045] In one embodiment, the elastic rope 50 can be a rubber rope or a silicone rope, which is not limited here.

[0046] In the embodiment of the present invention, initially, the traction assembly 60 is located at the upper left corner of the inner wall of the protective sleeve 20, so that the elastic rope 50 is located between the protective sleeve 20 and the camera body 10 and maintains a tilted left state. At this time, the elastic rope 50 will not block the normal camera operation of the camera body 10. When the lens of the camera body 10 needs to be cleaned, the traction assembly 60 can be driven by the driving assembly 40 to slide counterclockwise along the inner wall of the protective sleeve 20. When the traction assembly 60 slides counterclockwise, one end of the elastic rope 50 can be pulled to move along a counterclockwise trajectory until the traction assembly 60 slides to the upper right corner of the inner wall of the protective sleeve 20. The elastic rope 50 is detached from the lens side of the camera body 10 and is in a tilted right state. During the above process, the elastic rope 50 can be adaptively stretched and retracted, and the elastic rope 50 can be elastically stretched and retracted. During the movement, the rope 50 moves in contact with the side of the lens of the camera body 10, thereby scraping off dust and debris on the side of the lens of the camera body 10, thereby realizing automatic cleaning of the lens of the camera body 10; after the camera body 10 has been working for a certain period of time, the driving component 40 can drive the traction component 60 to slide clockwise along the inner wall of the protective sleeve 20, and when the traction component 60 slides clockwise, it can pull one end of the elastic rope 50 to move along a clockwise trajectory until the traction component 60 slides to the upper left corner position of the inner wall of the protective sleeve 20 again, the elastic rope 50 detaches from the side of the lens of the camera body 10 and is in a tilted state to the left, thereby realizing automatic cleaning of the lens of the camera body 10 again. Compared with the existing technology, it can realize automatic cleaning of the industrial camera lens, and has the advantages of good cleaning effect and high cleaning efficiency.

[0047] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present application.
