Description

Technical Field

[0001] The utility model relates to the technical field of visual detection, in particular to an installation mechanism for hot finishing rolling mill strip surface monitoring equipment. Background Art

[0002] After the metal strip is rolled, in order to detect the surface quality of the strip, it is often necessary to use surface monitoring equipment to perform real-time detection of the strip surface quality to ensure the production quality of the product.

[0003] Surface monitoring equipment is often installed above and / or below the strip to be tested to facilitate detection. However, in order to reduce roller wear and prevent metal adhesion, hot strip rolling mills often use emulsions for lubrication and cooling. However, due to the high rolling environment temperature, the emulsion easily forms steam, and these steams contain water mist and oil mist. After moving with the rolled strip, the steam will drip or adhere to the surface of the surface monitoring equipment, and the dust in the environment is also easy to fall on the surface of the surface monitoring equipment, thereby affecting the accuracy of the detection.

[0004] In addition, the surface monitoring equipment is generally fixedly installed. However, since the surface monitoring equipment is installed above or below the strip, these locations are not convenient for inspection and maintenance of the surface monitoring equipment.

[0005] In the prior art, in order to solve the above problems, a method of installing the surface monitoring equipment on a track is proposed. The track setting can facilitate the surface monitoring equipment to enter and exit the rolling line, and facilitate the inspection and maintenance of the surface monitoring equipment.

[0006] In order to reduce the impact of steam and dust on the detection results, the prior art discloses that a transparent plate (such as a glass plate) is arranged at the front end of an image acquisition unit of a surface monitoring device such as a camera, and then a purge pipe for blowing air to the transparent plate is installed, so that the airflow blown out by the purge pipe forms a protection on the transparent plate, thereby improving the accuracy of detection. For example, there is a mobile hot-rolled steel plate surface defect visual inspection device with patent announcement number CN210907405U. However, in this method, because the steam contains grease, once the steam adheres to the transparent plate, it is difficult to blow it clean even if it is blown. Therefore, after long-term use, the transparent plate is still easy to get dirty, thereby affecting the detection accuracy. Utility Model Content

[0007] The utility model aims to provide a hot finishing mill strip surface monitoring device installation mechanism to solve the problem that the surface monitoring device in the prior art is easily affected in detection accuracy due to the dirty transparent plate in surface quality detection.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] The installation mechanism of the surface monitoring equipment of the hot finishing rolling mill strip includes a frame for installing the surface monitoring equipment, a purge pipe for purging the front end of a camera of the surface monitoring equipment, and also includes a protective cover fixedly installed relative to the camera, the protective cover is provided with a camera port for the camera to take pictures, and the purge pipe is used to blow air toward the front end of the camera port.

[0010] The principles and advantages of this solution are: When this solution is adopted, the protective cover is set up so that the protective cover protects the space photographed by the camera, reducing the probability of steam and dust falling into the optical path of the camera, and the purge pipe blows air toward the front end of the camera port, so that an air curtain is formed in front of the camera port, further blocking dust and steam from entering the optical path of the camera, and the setting of the camera port facilitates the camera's shooting without being affected, thereby ensuring that after long-term use, the surface monitoring equipment can still collect clear and accurate images of the strip surface through the camera, thereby ensuring the accuracy of the detection.

[0011] Preferably, as an improvement, the cross-section of the protective cover is V-shaped.

[0012] Preferably, as an improvement, the camera is located in the housing of the surface monitoring device, a transparent plate is fixed on the housing to facilitate camera shooting, and the protective cover is located outside the housing and on the transparent plate. This solution protects the camera and ensures that the shooting of the picture is not affected.

[0013] Preferably, as an improvement, it also includes a guide plate arranged on the frame, the guide plate is located between the strip to be tested and the surface monitoring device, the guide plate is inclined, and an opening for a camera to take pictures is opened on the guide plate.

[0014] Beneficial effect: The existence of the inclined guide plate separates the strip and the surface monitoring equipment. On the one hand, it helps to reduce the impact of the surface temperature of the strip after hot rolling on the surface monitoring equipment. On the other hand, it also helps to isolate steam through the guide plate, further reducing the impact of steam on the surface monitoring equipment.

[0015] Preferably, as an improvement, it further comprises a rotatable or movable plate member, the plate member being used to cover the opening 1 to prevent the tape from being inserted into the opening 1 when threading the tape.

[0016] Preferably, as an improvement, the plate member is rotatably connected to the frame, and when the plate member is close to the strip, it is used to cover the opening one.

[0017] Preferably, as an improvement, the guide plate is provided with opening two, and also includes a plurality of fixedly installed cleaning nozzles, the cleaning nozzles are facing opening two, and the cleaning nozzles pass through opening two to facilitate the cleaning nozzles to spray the strip, thereby reducing the retention of dirt on the measured strip.

[0018] Preferably, as an improvement, the distance between the second opening and the measured strip is greater than the distance between the first opening and the measured strip, and the measured strip first passes through the second opening and then through the first opening.

[0019] Beneficial effect: This solution allows the tested strip to be first sprayed with a cleaning nozzle and then transported to the top of the opening 1 for surface quality inspection, which helps to improve the accuracy of the inspection.

[0020] Preferably, as an improvement, there are multiple openings 2, and the multiple openings 2 are distributed along the width direction of the strip, and each opening 2 corresponds to a cleaning nozzle.

[0021] Beneficial effect: by setting a plurality of openings 2, the size of each opening 2 can be set relatively small, which can prevent the strip from being inserted into the opening 2 when threading the strip, and can also reduce the total opening area of ​​the opening 2, thereby relatively helping to ensure the strength of the guide plate.

[0022] Preferably, as an improvement, a linear drive is installed on the frame, and the surface monitoring device is fixed to the output end of the linear drive, and the linear drive is used to drive the surface monitoring device to switch between the working area and the inspection area. This solution enables the surface monitoring device to be directly driven by the linear drive to move from the working position under the strip to the inspection area when it needs to be repaired, which facilitates the repair and maintenance of the surface monitoring device in a wider space.

[0033] Example

[0034] Combination Figures 1 to 8 The installation mechanism of the hot rolling mill strip surface monitoring equipment includes a frame 10 for installing the surface monitoring equipment 20. The frame 10 is divided into a working area and an inspection area. The working area is opposite to the strip to be tested, and the inspection area is located on one side of the working area to facilitate the inspection and maintenance of the surface monitoring equipment 20 in the inspection area.

[0035] A linear mover 30 is installed on the frame 10, and a track 31 is fixed on the frame 10. The length direction of the track 31 is parallel to the width direction of the strip. The output end of the linear mover 30 is fixed with a surface monitoring device 20. The linear mover 30 is used to drive the surface monitoring device 20 to move between the inspection area and the working area.

[0036] The specific linear mover 30 can be in the form of a mobile cart as in patent announcement number CN210907405U, or in the form of other linear modules. This embodiment adopts the form of a mobile cart with running wheels 32. The mobile cart includes multiple running wheels 32 and a driving motor 33. After the driving motor 33 is driven, the motor shaft 331 of the driving motor 33 drives the running wheels 32 to rotate, thereby driving the surface monitoring equipment 20 to move along the track 31.

[0037] The surface monitoring device 20 includes a housing 21 and a plurality of cameras 22 installed in the housing 21 . The housing 21 has a mounting hole, and a transparent plate 23 is fixed on the mounting hole. The transparent plate 23 ensures that the shooting lenses of the plurality of cameras 22 in the housing 21 are not blocked.

[0038] A plurality of V-shaped protective covers 24 are fixed to the outside of the shell 21. The number of the protective covers 24 is the same as the number of the cameras 22. Each protective cover 24 covers the shooting front end of the camera 22. The protective cover 24 is close to the transparent plate 23. The protective cover 24 has a camera port for the camera 22 to take pictures.

[0039] A plurality of purge pipes 25 are also fixed on the shell 21, and the number of the purge pipes 25 is not less than the number of the protective covers 24. The purge pipes 25 are used to blow air toward the front end of the camera port to form a transparent air curtain in front of the camera port, thereby ensuring that steam and dust are not easy to enter from the camera port to the transparent plate 23 blocked by the protective covers 24, thereby ensuring the cleanliness of the front transparent area captured by the camera 22 and ensuring the accuracy of the surface quality detection of the strip.

[0040] An inclined guide plate 40 is also fixedly mounted on the frame 10. The guide plate 40 is located between the strip to be tested and the surface monitoring device 20. The guide plate 40 has an opening 1 41 and multiple openings 2 42. The opening 2 42 is parallel to the opening 1 41. The opening 1 41 is used for the camera 22 to take pictures. The multiple openings 2 42 are distributed along the width direction of the strip. The distance between the opening 2 42 and the strip to be tested is greater than the distance between the opening 1 41 and the strip to be tested. When the strip to be tested is transmitted, it first passes through the opening 2 42 and then passes through the opening 1 41. The opening 2 42 is closer to the guide plate 40 and tilted downward.

[0041] A plate member is rotatably connected to the frame 10, and the plate member is used to cover the opening 41. In this embodiment, the plate member is a flap 50. When the flap 50 rotates toward the strip, the opening 41 is covered, and the free end of the flap 50 can pass through the opening 41, thereby forming a threading guide for the threading strip (the strip in this embodiment takes the aluminum strip 100 as an example), which can prevent the strip from being inserted into the opening 41 during threading. Specifically, the rotation center of the flap 50 is connected to a fork arm 51, and the fork arm 51 is connected to a driving cylinder 52. One end of the fork arm 51 is fixedly connected to the rotation center of the flip, and the other end of the fork arm 51 is rotatably connected to the output rod 53 of the driving cylinder 52. The housing 21 of the driving cylinder 52 is rotatably connected to the frame 10.

[0042] A plurality of cleaning nozzles 60 are fixedly mounted on the frame 10, and the cleaning nozzles 60 are connected to the spray pipes 61. Each opening 42 corresponds to a cleaning nozzle 60, and the cleaning nozzles 60 face the strip to be tested. The cleaning nozzles 60 pass through the opening 42 to facilitate the cleaning nozzles 60 to spray the strip.

[0043] In this embodiment, when the surface monitoring device 20 needs to be inspected, the linear mover 30 is controlled to start, thereby driving the surface monitoring device 20 to move from the working area to the inspection area, so as to facilitate the inspection or maintenance of the surface monitoring device 20.

[0044] When the surface monitoring device 20 is working, the steam generated by hot rolling is first blocked by the inclined guide plate 40, reducing the probability of steam or dust falling directly onto the surface monitoring device 20, and the setting of the opening 41 can ensure that the shooting path of the camera 22 is not blocked; then the gas blown out by the purge pipe 25 forms an air curtain at the camera port of the protective cover 24, further preventing steam or dust from falling from the camera port into the transparent plate 23 area covered by the protective cover 24, ensuring that the camera 22 can capture an accurately cleaned strip surface image when shooting, thereby ensuring the accuracy of the surface quality detection of the strip by the surface monitoring device 20.

[0045] The cleaning nozzle 60 on the second opening 42 sprays the strip so that the strip to be tested is first sprayed by the cleaning nozzle 60 and then transported to the top of the first opening 41 for surface quality testing, which further helps to improve the accuracy of the test.

[0046] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
