[0038] Figure 1 A schematic diagram of the structure of a protective device for a surface detection camera in an embodiment of the present application is shown. Figure 1 1 is the strip steel, 2 is the third mounting rod, 3 is the third detection element, 4 is the first detection element, 5 is the first surface detection camera, 6 is the first rack, 7 is the first mounting rod, 8 is the second mounting rod, 9 is the second surface detection camera, 10 is the second detection element, 11 is the second rack, see Figure 1 , a protective device for a surface inspection camera is provided, which at least includes a strip height detection mechanism and a controller, which are described in detail as follows:

[0039] The strip height detection mechanism is used to detect the height of the strip surface relative to the flat state to obtain a target detection height, wherein the target detection height is the strip surface height photographed by the target camera or the strip surface height at the strip entrance position.

[0040] Specifically, the target detection height can be understood as the height of the strip surface protruding from the flat state to the state away from the flat state. If the strip surface is in a flat state, the target detection height is zero. Figure 1 Take the upper surface of the strip as an example, the target detection height is the upper surface of the strip relative to Figure 1 The convex height of the upper surface state of the strip, that is, the height of the upper surface of the strip convex upward. The first surface detection camera shoots the upper surface of the strip from the upper right to the lower left. The strip surface photographed by the surface detection camera is the upper surface of the strip on the left side of the first rack, and the strip entrance position is the strip surface on the left side of the second rack.

[0041] The controller is connected to the strip steel height detection mechanism and is used to control the target strip steel production line to stop when the target detection height is greater than a preset height, and the preset height is less than the closest distance between the surface detection camera and the strip steel surface.

[0042] Specifically, the preset height corresponding to the strip surface photographed by the surface detection camera may be different from the preset height corresponding to the strip surface at the strip entrance position, or they may be the same. Controlling the target strip production line to stop can avoid further increase in the target detection height and damage to the surface detection camera caused by the strip surface. The target strip production line is the strip production line corresponding to the target detection height.

[0043] Optionally, when the target detection height is less than or equal to a preset height, the controller controls the target strip steel production line to produce normally.

[0044] Optionally, the strip steel height detection mechanism comprises:

[0045] The first detection component is used to detect the surface height of the strip steel photographed by the target camera.

[0046] Optionally, the first detection component includes:

[0047] A first detection member, used for detecting the height of a first surface of the steel strip, and located outside the shooting range of the surface detection camera;

[0048] The second detection member is used to detect the height of the second surface of the steel strip, where the second surface of the steel strip is relatively distributed with respect to the first surface and is outside the shooting range of the surface detection camera.

[0049] Specifically, the first detection member and the second detection member are located outside the shooting range of the surface detection camera to prevent the first detection member and the second detection member from blocking the surface detection camera and affecting the surface detection camera's shooting of the strip surface.

[0050] by Figure 1For example, if the first surface of the steel strip is the upper surface of the steel strip, and the second surface of the steel strip is the lower surface of the steel strip, the first surface detection camera shoots the upper surface of the steel strip, and the shooting direction is from the upper right to the lower left. The first detection component is located directly below the first surface detection camera, so that the first detection component is outside the shooting range of the first surface detection camera. Similarly, the second surface detection camera shoots the lower surface of the steel strip, and the shooting direction is from the lower right to the upper left. The second detection component is located directly above the second surface detection camera, so that the second detection component is outside the shooting range of the second surface detection camera.

[0051] Optionally, the first detection component includes:

[0052] The first mounting rod is arranged on the frame of the target strip steel production line, and its axial direction is distributed along the width direction of the strip steel, and is located between the surface detection camera shooting the first surface of the strip steel and the first surface of the strip steel, and there is a gap between the first mounting rod and the first surface of the strip steel to prevent the first mounting rod from affecting the normal production of the strip steel. The size of the gap can be set according to actual conditions. Figure 1 In the invention, the first mounting rod is arranged on the first frame;

[0053] The first detection element is arranged on the first mounting rod, has an initial detection height equal to a preset height, is used to detect the height of the first surface of the steel strip, and is electrically connected to the controller.

[0054] Specifically, the initial detection height of the first detection element is equal to the preset height. It can be understood that when the target detection height reaches the preset height, the first detection element starts to detect the target detection height of the strip surface. Figure 1 For example, the first detection element is installed on the upper surface of the first mounting rod, and the distance between the upper surface of the first mounting rod and the upper surface of the strip is equal to a preset height. When the target detection height of the upper surface of the strip is equal to the preset height, the first detection element begins to detect the target detection height of the strip surface.

[0055] Optionally, the first detection element is a first diffuse reflection photoelectric switch or a first travel switch, the detection light of the first diffuse reflection photoelectric switch is parallel to the length direction of the strip, the first travel switch is a roller type travel switch and its roller protrudes from the first mounting rod, so that when the first surface of the strip is lifted, it contacts the first surface of the strip, that is, when the target detection height of the first surface of the strip is greater than or equal to a preset height, the first surface of the strip and the roller are in contact, thereby triggering the first travel switch.

[0056] by Figure 1For example, if the first detection element is a first diffuse reflection photoelectric switch, when the height of the upper surface of the strip is equal to the preset height, that is, the height of the upper surface of the strip on the left side of the first mounting rod is equal to the preset height, the detection light of the first diffuse reflection photoelectric switch is blocked by the upper surface of the strip, and the first diffuse reflection photoelectric switch sends a signal to the controller, and the controller controls the target strip production line to stop. If the first detection element is a first stroke switch, when the height of the upper surface of the strip is equal to the preset height, that is, the height of the upper surface of the strip on the left side of the first mounting rod is equal to the preset height, the upper surface of the strip contacts the roller of the first stroke switch, and the first stroke switch sends a signal to the controller, and the controller controls the target strip production line to stop.

[0057] Optionally, the second detection member includes:

[0058] The second mounting rod is arranged on the frame of the target strip steel production line, and its axial direction is distributed along the width direction of the strip steel, and is located between the surface detection camera photographing the second surface of the strip steel and the second surface of the strip steel, and there is a gap between the second mounting rod and the second surface of the strip steel to prevent the second mounting rod from affecting the normal production of the strip steel. The size of the gap can be set according to actual conditions. Figure 1 In the invention, the second mounting rod is arranged on the first frame;

[0059] The second detection element is arranged on the second mounting rod, and its initial detection height is equal to the preset height. It is used to detect the height of the second surface of the steel strip and is electrically connected to the controller.

[0060] Specifically, the initial detection height of the second detection element is equal to the preset height. It can be understood that when the target detection height reaches the preset height, the second detection element starts to detect the target detection height of the strip surface. Figure 1 For example, the second detection element is installed on the lower surface of the second mounting rod, and the distance between the lower surface of the second mounting rod and the lower surface of the strip is equal to a preset height. When the target detection height of the lower surface of the strip is equal to the preset height, the second detection element begins to detect the target detection height of the strip surface.

[0061] Optionally, the second detection element is a second diffuse reflection photoelectric switch or a second travel switch, the detection light of the second diffuse reflection photoelectric switch is parallel to the length direction of the strip, the second travel switch is a roller type travel switch and its roller protrudes from the second mounting rod so that the second surface of the strip is contacted when the second surface of the strip is lifted.

[0062] by Figure 1For example, if the second detection element is a second diffuse reflection photoelectric switch, when the height of the lower surface of the strip is equal to the preset height, that is, the height of the lower surface of the strip on the left side of the second mounting rod is equal to the preset height, the detection light of the second diffuse reflection photoelectric switch is blocked by the lower surface of the strip, and the second diffuse reflection photoelectric switch sends a signal to the controller, and the controller controls the target strip production line to stop. If the second detection element is a second stroke switch, when the height of the lower surface of the strip is equal to the preset height, that is, the height of the lower surface of the strip on the left side of the second mounting rod is equal to the preset height, the lower surface of the strip contacts the roller of the second stroke switch, and the second stroke switch sends a signal to the controller, and the controller controls the target strip production line to stop.

[0063] Optionally, the strip steel height detection mechanism comprises:

[0064] The second detection component is used to detect the surface height of the strip at the strip entrance position.

[0065] Optionally, the second detection component includes:

[0066] The third mounting rod is arranged on the frame of the target strip steel production line, and its axial direction is distributed along the width direction of the strip steel, and is located at the strip steel entrance position, with a gap between it and the strip steel surface;

[0067] The third detection element is arranged on the third mounting rod, and its initial detection height is equal to the preset height. It is used to detect the height of the surface of the steel strip and is electrically connected to the controller.

[0068] Optionally, the third detection element is a third diffuse reflection photoelectric switch or a third travel switch, the detection light of the third diffuse reflection photoelectric switch is parallel to the length direction of the strip, and the third travel switch is a roller type travel switch and its roller protrudes from the third mounting rod so that it contacts the surface of the strip when the strip is lifted.

[0069] by Figure 1 For example, if the third detection element is a third diffuse reflection photoelectric switch, when the surface height of the strip is equal to the preset height, that is, the height of the strip surface on the left side of the third mounting rod is equal to the preset height, the detection light of the third diffuse reflection photoelectric switch is blocked by the strip surface, and the third diffuse reflection photoelectric switch sends a signal to the controller, and the controller controls the target strip production line to stop. If the third detection element is a third stroke switch, when the surface height of the strip is equal to the preset height, that is, the height of the strip surface on the left side of the third mounting rod is equal to the preset height, the strip surface and the roller of the third stroke switch are in contact, and the third stroke switch sends a signal to the controller, and the controller controls the target strip production line to stop.

[0070] It should be understood that the strip surface on the left side of the second rack is far away from the surface detection camera. However, when the strip surface on the left side of the second rack is lifted, it is easy to cause the strip surface between the first rack and the second rack to be lifted, affecting the surface detection camera. Therefore, it is necessary to detect the strip surface on the left side of the second rack, that is, the strip entrance position.

[0071] In the present application, the strip inlet position can be understood as the inlet position where the strip enters the equipment, or the gap between the previous equipment and the current equipment.

[0072] In the present application, the height of the strip surface is detected by a strip height detection mechanism to obtain a target detection height. When the strip is being sleeved, the target detection height can be understood as the sleeving height. If the target detection height is greater than the preset height, the controller controls the target strip production line to stop to prevent the strip sleeving height from further increasing, impacting or squeezing the camera, and causing damage to the surface detection camera.

Among them, the device embodiments described above are only schematic. For example, the division of the units can be a logical function division.
