Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate detection, in particular to an aluminum plate detection device and system. Background Art

[0002] As a lightweight metal material widely used in industries, construction, aerospace and other fields, the quality and reliability of aluminum plates have an important impact on the performance and safety of products. During the production process of aluminum plates, they may be affected by various factors, such as material defects, processing errors, environmental factors, etc., resulting in defects such as cracks, pores, inclusions, protrusions, depressions, etc. on the inside or surface of the aluminum plates. These defects not only affect the performance and service life of the aluminum plates, but also may pose a threat to the safety and reliability of the products made of the aluminum plates.

[0003] Currently, most of the traditional defect detection technologies for the inside or surface of aluminum plates adopt ultrasonic non-destructive testing technology. For example, Chinese Patent Publication No. CN219695005U discloses a high-performance aluminum plate surface defect ultrasonic flaw detector, which includes a workbench, a clamping group and a support rod are arranged on the workbench, a two-layer plate is arranged on the support rod, a detection opening is formed on the two-layer plate, and a controller, an adjusting cylinder and a rodless cylinder are electrically connected. By arranging a two-layer plate with a detection opening and a chute on the workbench, arranging a controller and an adjusting cylinder on the two-layer plate, sliding an adjusting frame with a rodless cylinder in the chute, and arranging a probe on the sliding seat of the rodless cylinder, a comprehensive and effective flaw detection of the aluminum plate body is realized.

[0004] However, through the solutions disclosed in the above-mentioned existing patent documents, it can be seen that for the existing flaw detection devices for aluminum plate defects, they need to sequentially traverse the surface of the aluminum plate through the probe to complete the flaw detection of the full coverage of the aluminum plate, resulting in a slow flaw detection speed of the flaw detection device, and when there are convex defects on the surface of the aluminum plate, there is a risk of damage to the probe when the probe slides over the convex surface.

[0005] Therefore, there is an urgent need for a detection device that can quickly complete the detection of aluminum plate defects to improve the safety of the probe. Summary of the Utility Model

[0043] In order to better explain the present utility model for easy understanding, the present utility model will be described in detail below with reference to the accompanying drawings through specific embodiments.

[0044] Reference Figures 1-3As shown in the figure, a kind of aluminum plate detection device proposed by the embodiment of the present utility model includes: a rotation detection mechanism 100 and an aluminum plate transmission mechanism 200; the rotation detection mechanism 100 includes a first roller 110, a second roller 120 and a pressure sensor arranged inside the first roller 110 and the second roller 120. The first roller 110 and the second roller 120 are respectively arranged on the same axis on both sides of the aluminum plate transmission mechanism 200; a plurality of sliding members 130 capable of horizontally sliding towards the center of the roller are arranged on the outer sides of the first roller 110 and the second roller 120. The outer sides of the sliding members 130 are used to contact the aluminum plate 300, and the inner sides of the sliding members 130 are connected to the pressure sensor; an ultrasonic probe is also attached to the outer side of each sliding member 130 in the first roller 110 for ultrasonic flaw detection of the aluminum plate 300.

[0045] For the aluminum plate detection device proposed by the present utility model, its rotation detection mechanism 100 includes two rollers, and an ultrasonic probe is attached to the outer side of one of the rollers to perform full-coverage ultrasonic flaw detection on the aluminum plate 300 in the way of roller rotation detection. The aluminum plate transmission mechanism 200 is used to convey the aluminum plate 300 to the detection area of the rotation detection mechanism 100 for full-coverage flaw detection. Compared with the prior art, after the aluminum plate 300 passes through the detection area of the rotation detection mechanism 100, the flaw detection work on the inside and surface of the aluminum plate 300 can be completed, greatly improving the speed of aluminum plate flaw detection.

[0046] At the same time, the present utility model also arranges sliding members 130 on the outer sides of the two rollers, and the inner sides of the sliding members 130 are connected to the pressure sensor. When there is a raised block on the aluminum plate 300, after the raised block contacts the sliding member 130, the sliding member 130 slides inward to apply pressure to the pressure sensor, and the position of the sliding member 130 can be located through the pressure sensor, and the position of the raised block in the aluminum plate 300 can be obtained. Moreover, after the sliding member 130 contacts the raised block, it can slide inward to protect the ultrasonic probe arranged on the outer side of the sliding member 130 from being damaged by the raised block, thereby improving the safety of the ultrasonic probe.

[0047] In order to better understand the above technical solution, the exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more clear and thorough understanding of the present utility model and to be able to convey the scope of the present utility model completely to those skilled in the art.

[0048] Specifically, the rotation detection mechanism 100 includes a first roller 110, a second roller 120, a first regulator 170, and pressure sensors, pressure encoders, and springs 160 disposed inside the first roller 110 and the second roller 120. The first roller 110 and the second roller 120 are respectively disposed on the same axis on both sides of the aluminum plate transmission mechanism 200, and the distance between the first roller 110 and the second roller 120 can be adjusted by the first regulator 170 to be consistent with the thickness of the aluminum plate 300.

[0049] Further, a plurality of sliding members 130 capable of horizontally sliding in the direction of the center of the roller are provided on the outer sides of the first roller 110 and the second roller 120. The outer sides of the sliding members 130 are used to contact the aluminum plate 300. The inner sides of the sliding members 130 are connected to the pressure sensors, and each sliding member 130 is connected to a pressure sensor. An ultrasonic probe is also attached to the outer side of each sliding member 130 in the first roller 110 for ultrasonic flaw detection of the aluminum plate 300. When there is a raised block on the aluminum plate 300, after the raised block contacts the sliding member 130, the raised block pushes the sliding member 130 to horizontally slide in the direction of the center of the roller. The sliding member 130 applies pressure to the pressure sensor. Based on the pressure signal generated by the pressure sensor, one or more sliding members 130 that have slid can be positioned, thereby determining the position of the raised block on the aluminum plate 300, achieving the technical effect of detecting the raised defect on the surface of the aluminum plate 300. At the same time, the horizontal sliding of the sliding member 130 in the direction of the center of the roller can also better protect the ultrasonic probe disposed on the outer side of the sliding member 130 from being damaged by the raised block.

[0050] Further, the encoder includes: a code disk 141 and a brush 142. The code disk 141 is disposed on the transmission shaft 150 of the first roller 110 and the second roller 120. The brush 142 contacts the code disk 141 and is used to collect the angular displacement data when the transmission shaft 150 rotates. When the code disk 141 rotates synchronously with the transmission shaft 150, an encoded output is generated at the contact between the brush 142 and the code disk 141. The angular displacement data when the transmission shaft 150 rotates can be obtained through the output encoded information, and then the position where each sliding member 130 contacts the aluminum plate 300 can be obtained. Therefore, within the same time period, the rotational displacement amounts of the first roller 110 and the second roller 120 need to be consistent with the linear displacement amount of the aluminum plate 300 on the forward track 221.

[0051] Furthermore, one end of the spring 160 is connected to the inner side of the sliding member 130, and the other end of the spring 160 is connected to the pressure sensor. When the outer side of the sliding member 130 is flush with the outer side of the first roller 110 or the second roller 120, the length of the spring 160 is in a natural state, and the pressure sensor has no pressure signal output. When the sliding member 130 is impacted by the raised block of the aluminum plate 300, the sliding member 130 slides toward the center of the roller, causing the spring 160 to be compressed, and the pressure sensor receives the pressure of the spring 160 to output a pressure signal. After the raised block is taken away from the rotation detection mechanism 100 by the aluminum plate transmission mechanism 200, the spring 160 returns to the natural state, pushes the sliding member 130 to the original position, and keeps the outer side of the sliding member 130 flush with the outer side of the first roller 110 or the second roller 120.

[0052] Furthermore, the first regulator 170 is connected to the first roller 110 and the second roller 120 respectively, and is used to adjust the distance between the first roller 110 and the second roller 120 to be consistent with the thickness of the aluminum plate 300. When the distance between the first roller 110 and the second roller 120 is consistent with the thickness of the aluminum plate 300, the ultrasonic probe disposed on the first roller 110 can be attached to the surface of the aluminum plate 300 for detection, thereby improving the detection accuracy.

[0053] Furthermore, a marker is attached to the outer side of the sliding member 130; the marker is configured with at least two marking patterns, and the marker is used to mark the position of the defect in the aluminum plate 300 with a specific pattern. For example, the convex defect on the surface of the aluminum plate 300 is marked by a red circle, and the pore defect inside the aluminum plate 300 is marked by a black square. After marking the defects on the surface and inside of the aluminum plate 300 with different patterns, the staff can quickly observe the specific location of the defect and know the defect type.

[0054] The aluminum plate transmission mechanism 200 includes: a push trolley 210 and a conveying track 220. The push trolley 210 is arranged on the conveying track 220, and is used to push the aluminum plate 300 forward on the conveying track 220. The conveying track 220 is provided with a forward track 221, a return track 222, a lifter and an aluminum plate limiter assembly; the forward track 221 is arranged on the surface of the conveying track 220, and is used to assist the push trolley 210 in pushing the aluminum plate 300 to slide forward; the return track 222 is arranged inside the conveying track 220, and is used to assist the push trolley 210 to return from the end of the conveying track 220 to the starting point of the conveying track 220; the aluminum plate limiter assembly is arranged on both sides of the forward track 221, and is used to limit the aluminum plate 300 in the forward position to prevent the aluminum plate 300 from tipping over; the lifter is arranged at the beginning and end of the conveying track 220, and is used to lower the push trolley 210 from the forward track 221 to the return track 222 or to lift the push trolley 210 from the return track 222 to the forward track 221.

[0055] Further, the aluminum plate limiting assembly includes: a first limiting member 223, a second limiting member 224, and a second adjuster 180; the first limiting member 223 and the second limiting member 224 are respectively arranged on the same axis on both sides of the forward track 221; the second adjuster 180 is respectively connected to the first limiting member 223 and the second limiting member 224, and is used to adjust the distance between the first limiting member 223 and the second limiting member 224 to be consistent with the thickness of the aluminum plate 300.

[0056] It is worth mentioning that the lateral width of the propulsion trolley 210 is smaller than the minimum thickness of the aluminum plate 300.

[0057] On the other hand, the present invention also proposes an aluminum plate detection system, which includes:

[0058] A thickness measuring caliper for detecting the thickness of the aluminum plate.

[0059] A laser scanner for detecting the surface roughness of the aluminum plate.

[0060] The above-mentioned aluminum plate detection device is used to detect the convex defects on the surface of the aluminum plate and perform ultrasonic flaw detection on the inside of the aluminum plate.

[0061] In summary, an aluminum plate detection device and system proposed by the present invention, the aluminum plate detection device mainly includes: a rotation detection mechanism 100 and an aluminum plate transmission mechanism 200. The rotation detection mechanism 100 is used for comprehensive detection of the defects on the surface and inside of the aluminum plate 300, and the aluminum plate transmission mechanism 200 is used to push the aluminum plate 300 to the monitoring area of the rotation detection mechanism 100.
