Description

Technical Field

[0001] The utility model relates to the field of steel plate defect detection, in particular to a steel plate surface hole detection device. Background Art

[0002] Steel plates, as important industrial products, often require different types of coatings for diverse applications. Due to numerous uncontrollable factors, such as equipment and operator error, coating defects are inevitable. Holes, a common type of coating defect, can severely impact the service life of steel plates. Therefore, companies now routinely inspect the coating after application.

[0003] Patent publication CN205920059U discloses a tool for detecting surface defects of steel plates. In this detection tool, steel plates are transported by a conveyor belt, and a camera located above the conveyor belt is used to detect the steel plates. Since there is no object above the conveyor belt to press down the steel plates, when the device uses the conveyor belt to transport the steel plates, the steel plates are prone to movement due to the start and stop of the conveyor belt, and the movement of the steel plates is likely to cause detection errors. Utility Model Content

[0004] In view of the above problems, the utility model proposes a steel plate surface hole detection device.

[0005] The technical solutions adopted by this utility model are as follows:

[0006] A steel plate surface hole detection device includes a base, a conveyor belt is provided on the base, a bracket is provided on the base, the bracket is located above the conveyor belt, an industrial camera is provided on the bracket, the industrial camera is located above the conveyor belt, and the device also includes a rotating frame, a mounting plate and a plurality of rollers, the rotating frame is rotatably mounted on the bracket, there are two mounting plates, the two mounting plates are rotatably arranged at the two ends of the rotating frame, the two mounting plates are in a parallel state, the two ends of the roller are respectively rotatably matched with the two mounting plates, and all the rollers are in a parallel state, and all the rollers are parallel to the conveyor belt, and the rollers have a tendency to move closer to the conveyor belt.

[0007] When this device is performing detection, when the steel plate is transported on the conveyor belt and passes under the industrial camera, the industrial camera takes a picture of its surface and determines whether there are holes in the steel plate coating by analyzing the photo information.

[0008] In this device, the rotating frame is located above the conveyor belt, and the rotating frame is rotatably mounted on the bracket. The roller itself has a tendency to move closer to the conveyor belt, so when a steel plate is conveyed on the conveyor belt, the roller on the rotating frame can press the steel plate. Since the roller is rotatably mounted on the mounting plate, the mounting plate can rotate relative to the rotating frame, and the rotating frame can rotate relative to the bracket, it is equivalent to a roller pressing on the top of the steel plate, and the roller can rotate relative to the steel plate. This is equivalent to a relatively rotatable object being pressed on the top of the steel plate, which reduces the probability of the steel plate moving during transportation by the conveyor belt and improves the accuracy of the industrial camera's detection of holes on its surface.

[0009] At the same time, in this device, multiple rotatable rollers are set through the auxiliary connection function of the mounting plate. The presence of multiple rollers can ensure the probability of the steel plate being pressed by an object.

[0010] In summary, this device sets a rotatable roller above the conveyor belt, and uses the roller to play a certain guiding and clamping role on the steel plate being conveyed, thereby reducing the probability of the steel plate moving when being conveyed by the conveyor belt.

[0011] Optionally, a cross bar is further included, a guide rail is provided on the bracket, the cross bar slides together with the guide rail through its own notch, a bolt is rotatably provided in the through hole of the bracket, the bolt on the bracket cooperates with the screw hole on the cross bar, and the industrial camera is set on the cross bar.

[0012] The notch on the specific crossbar cooperates with the guide rail, and the crossbar can slide up and down along the guide rail. Since a bolt is rotatably arranged in the through hole of the bracket, the bolt on the bracket cooperates with the screw hole on the crossbar, so rotating the bolt can drive the crossbar to move along the guide rail. In this way, the height of the crossbar relative to the conveyor belt can be adjusted, thereby realizing the adjustment of the height of the industrial camera relative to the conveyor belt to better meet the detection needs.

[0013] Optionally, there are four guide rails, and four notches are provided on the crossbar, each notch is slidably engaged with a guide rail, and two guide rails are provided on each side of the crossbar.

[0014] There are four guide rails, which are located on both sides of the crossbar. This is equivalent to the guide rails clamping the crossbar from both sides to ensure that the crossbar remains stable when moving up and down and that the crossbar does not deviate.

[0015] Optionally, a spring is further included, which is sleeved on the bolt, with two ends of the spring respectively pressing against the cross bar and the bracket, and the central axis of the spring coincides with the central axis of the spring.

[0016] Set up a spring, and let one end of the spring press against the crossbar, and the other end of the spring press against the bracket. This can reduce the probability of the crossbar shaking up and down due to external force and improve the stability of the crossbar installation.

[0017] Optionally, central shafts are provided at both ends of the rotating frame, and the central shafts are rotatably engaged with the shaft holes on the bracket.

[0018] Optionally, it also includes an adjusting block, a mounting block and an adjusting screw, wherein the adjusting block is rotatably set on the rotating frame, the mounting block is rotatably mounted on the bracket, a screw hole is opened on the mounting block, the adjusting screw is installed in the screw hole of the mounting block, and one end of the adjusting screw is fixed to the adjusting block.

[0019] The rotating frame is installed on the bracket through the central axis, and the adjusting block and the mounting plate are respectively located on both sides of the rotating frame. One end of the adjusting screw is fixedly matched with the adjusting block, and the adjusting screw itself is matched with the mounting block through threaded matching. Since the mounting block can rotate relative to the bracket and the adjusting block can also rotate relative to the rotating frame, the position of the roller relative to the conveyor belt can be adjusted by turning the adjusting screw, which is equivalent to fixing the roller at a certain position above the conveyor belt, and the fixed position can be adjusted by turning the adjusting screw. This method of temporarily fixing the height of the roller can more stably guide the clamping steel plate (relative to the method in which the roller can swing up and down freely).

[0020] Optionally, a handle is fixed to one end of the adjusting screw.

[0021] The function of setting the handle is to facilitate turning the adjusting screw.

[0022] The beneficial effect of the utility model is that a rotatable roller is arranged above the conveyor belt, and the roller is used to play a certain guiding and clamping role on the steel plate being conveyed, thereby reducing the probability of the steel plate moving when being conveyed by the conveyor belt.

DETAILED DESCRIPTION

[0028] The present invention will be described in detail below with reference to the accompanying drawings.

[0029] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, a steel plate surface hole detection device includes a base 1, a conveyor belt 2 is provided on the base 1, a bracket 3 is provided on the base 1, the bracket 3 is located above the conveyor belt 2, an industrial camera is provided on the bracket 3, and the industrial camera is located above the conveyor belt 2. It also includes a rotating frame 12, a mounting plate 13 and a plurality of rollers 14, the rotating frame 12 is rotatably mounted on the bracket 3, there are two mounting plates 13, the two mounting plates 13 are rotatably arranged at the two ends of the rotating frame 12, the two mounting plates 13 are in a parallel state, the two ends of the roller 14 are respectively rotatably matched with the two mounting plates 13, and all the rollers 14 are in a parallel state, and all the rollers 14 are parallel to the conveyor belt 2, and the rollers 14 have a tendency to move closer to the conveyor belt 2.

[0030] When the device is performing detection, when the steel plate is transported on the conveyor belt 2 and passes under the industrial camera, the industrial camera takes a picture of its surface and determines whether there are holes in the steel plate coating by analyzing the photo information.

[0031] In this device, the rotating frame 12 is located above the conveyor belt 2, and the rotating frame 12 is rotatably mounted on the bracket 3. The roller 14 itself has a tendency to move closer to the conveyor belt 2, so when a steel plate is conveyed on the conveyor belt 2, the roller 14 on the rotating frame 12 can press the steel plate. Since the roller 14 is rotatably mounted on the mounting plate 13, the mounting plate 13 can rotate relative to the rotating frame 12, and the rotating frame 12 can rotate relative to the bracket 3, it is equivalent to a roller 14 being pressed above the steel plate, and the roller 14 can rotate relative to the steel plate. This is equivalent to a relatively rotatable object being pressed above the steel plate, which reduces the probability of the steel plate moving during transportation by the conveyor belt 2 and improves the accuracy of the industrial camera in detecting holes on its surface.

[0032] At the same time, in this device, multiple rotatable rollers are provided through the auxiliary connection function of the mounting plate 13. The presence of multiple rollers 14 can ensure the probability of objects being pressed on the top of the steel plate.

[0033] In summary, this device is provided with a rotatable roller 14 above the conveyor belt 2, and the roller 14 is used to play a certain guiding and clamping role on the steel plate being conveyed, thereby reducing the probability of the steel plate moving when being conveyed by the conveyor belt 2.

[0034] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, it also includes a cross bar 6, and a guide rail 7 is provided on the bracket 3. The cross bar 6 slides together with the guide rail 7 through its own notch 601. A bolt 4 is rotatably provided in the through hole of the bracket 3. The bolt 4 on the bracket 3 cooperates with the screw hole on the cross bar 6, and the industrial camera is set on the cross bar 6.

[0035] Specifically, the notch 601 on the cross bar 6 cooperates with the guide rail 7, and the cross bar 6 can slide up and down along the guide rail 7. Since a bolt 4 is rotatably arranged in the through hole of the bracket 3, the bolt 4 on the bracket 3 cooperates with the screw hole on the cross bar 6, so rotating the bolt 4 can drive the cross bar 6 to move along the guide rail 7. In this way, the height of the cross bar 6 relative to the conveyor belt 2 can be adjusted, thereby realizing the adjustment of the height of the industrial camera relative to the conveyor belt 2 to better adapt to the detection needs.

[0036] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, there are four guide rails 7 , and four notches 601 are provided on the crossbar 6 . Each notch 601 is slidably fitted with a guide rail 7 , and two guide rails 7 are provided on each side of the crossbar 6 .

[0037] There are four guide rails 7, which are located on both sides of the crossbar 6, which is equivalent to the guide rails 7 clamping the crossbar 6 from both sides to ensure that the crossbar 6 remains stable when moving up and down, and the crossbar 6 will not be offset.

[0038] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, a spring 5 is also included. The spring 5 is sleeved on the bolt 4. The two ends of the spring 5 respectively press against the cross bar 6 and the bracket 3. The central axis of the spring 5 coincides with the central axis of the spring 5.

[0039] A spring 5 is provided, and one end of the spring 5 is pressed against the crossbar 6, and the other end of the spring 5 is pressed against the bracket 3. This can reduce the probability of the crossbar 6 shaking up and down due to external force, and improve the stability of the installation of the crossbar 6.

[0040] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4As shown, a central shaft 15 is provided at both ends of the rotating frame 12 , and the central shaft 15 is rotatably matched with the shaft hole on the bracket 3 .

[0041] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, it also includes an adjusting block 11, a mounting block 10 and an adjusting screw 9. The adjusting block 11 is rotatably set on the rotating frame 12, and the mounting block 10 is rotatably mounted on the bracket 3. A screw hole is opened on the mounting block 10, and the adjusting screw 9 is installed in the screw hole of the mounting block 10. One end of the adjusting screw 9 is fixed to the adjusting block 11.

[0042] The rotating frame 12 is mounted on the bracket 3 through the central axis 15, and the adjusting block 11 and the mounting plate 13 are respectively located on both sides of the rotating frame 12. One end of the adjusting screw 9 is fixedly matched with the adjusting block 11, and the adjusting screw 9 itself is matched with the mounting block 10 by threaded matching. Since the mounting block 10 can rotate relative to the bracket 3 and the adjusting block 11 can also rotate relative to the rotating frame 12, the position of the roller 14 relative to the conveyor belt 2 can be adjusted by twisting the adjusting screw 9, and it is equivalent to fixing the roller 14 at a certain position above the conveyor belt 2, and the fixed position can be adjusted by twisting the adjusting screw 9. This method of temporarily fixing the height of the roller 14 can more stably guide the clamping steel plate (relative to the method in which the roller 14 can swing up and down freely).

[0043] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, a handle 8 is fixed to one end of the adjusting screw 9.

[0044] The handle 8 is provided to facilitate the turning of the adjusting screw.
