Description

Technical Field

[0001] This utility model relates to the technical field of aluminum sheet inspection devices, and in particular to an aluminum sheet surface defect inspection device. Background Technology

[0002] Aluminum sheet is a type of aluminum material. It refers to sheet aluminum products manufactured by plastic processing methods such as rolling, extrusion, stretching, and forging of aluminum billets. To ensure the final performance of the sheet, the finished product undergoes annealing, solution treatment, quenching, natural aging, and artificial aging treatments. Defect detection usually refers to the detection of surface defects in an item. Surface defect detection uses advanced machine vision inspection technology to detect defects such as spots, pits, scratches, color differences, and defects on the surface of the workpiece.

[0003] The existing method involves placing a prepared aluminum sheet sample on the conveyor belt of the testing equipment, then transporting it to the testing area and starting the testing equipment. The camera then captures images of the aluminum sheet surface, and the acquired images are preprocessed. Image processing algorithms are used to extract feature information from the aluminum sheet surface. Machine learning or deep learning algorithms are then used to analyze and compare the extracted feature information, and finally, defects on the aluminum sheet surface are detected.

[0004] However, if the aluminum sheet is not positioned correctly when placed on the conveyor belt, and the position shifts during transmission, the camera may be unable to capture a complete surface image, or the captured image quality may be poor. Utility Model Content

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3This is the first embodiment of the present invention, which provides an aluminum sheet surface defect detection device, including a detection box 1. A conveyor platform 2 is fixed to the bottom of the detection box 1, and a limit box 3 is fixed to the top of the conveyor platform 2. A limit component 4 is installed inside the limit box 3, and a cleaning component 5 is installed on the outer wall of the limit box 3. The limit component 4 includes a limit rod 401 symmetrically fixed to the top of the conveyor platform 2. A limit plate 402 is movably connected to the outer wall of the limit rod 401. A sliding column 403 is fixed to the top of the limit plate 402. An adjusting plate 404 is slidably connected to the outer wall of the sliding column 403. A connecting plate 405 is fixed to the top of the adjusting plate 404, and the top of the connecting plate 405 is slidably connected to the inner side of the limit box 3.

[0030] Specifically, an electric push rod 406 is fixed inside the limiting box 3. The output end of the electric push rod 406 is fixed to the outer wall of the connecting plate 405. The connecting plate 405 is slidably connected to the inner side of the limiting box 3 via a guide rail. The top of the adjusting plate 404 is symmetrically provided with inclined grooves 407. The inclined grooves 407 are slidably connected to the outer wall of the sliding column 403. Conveying rollers are symmetrically installed inside the conveying table 2. A conveyor belt 7 is provided on the outer wall of the conveying rollers. How the conveying rollers cooperate with the conveyor belt 7 to drive the aluminum sheet for conveying is existing technology and can be easily understood by those skilled in the art. Therefore, it will not be elaborated on here. Two support feet 6 are symmetrically fixed at the bottom of the conveying table 2. Shock-absorbing pads are fixed at the bottom of the support feet 6.

[0031] Furthermore, when the aluminum sheet is placed on the conveyor belt 7 for conveying, the connecting plate 405 is driven to slide by activating the electric push rod 406. Then, the connecting plate 405 drives the adjusting plate 404 to slide, which in turn drives the sliding column 403 to slide in the inclined slide groove 407. This causes the limiting plate 402 to be centered and limited on the limiting rod 401 according to the size of the aluminum sheet.

[0032] Example 2

[0033] Reference Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment. The cleaning component 5 includes a fixing frame 501 fixed to the outer wall of the limiting box 3. A cleaning plate 502 is slidably connected inside the fixing frame 501. A fixing rod 503 is fixed to the bottom of the cleaning plate 502. A spring 504 is sleeved on the outer wall of the fixing rod 503. One end of the spring 504 is fixed to the bottom of the cleaning plate 502, and the other end of the spring 504 is fixed to the inner side of the fixing frame 501. A limiting hole 505 is opened on the inner side of the fixing block, and the limiting hole 505 is slidably connected to the fixing rod 503.

[0034] Specifically, the cleaning plate 502 has bristles 506 evenly spaced at the bottom. The cleaning plate 502 is slidably connected to the outer wall of the limiting box 3 via a guide rail. The outer wall of the fixing frame 501 has a lifting groove 507. The outer wall of the cleaning plate 502 is fixed with a lifting rod 508. The lifting rod 508 is slidably connected to the lifting groove 507. A handle 509 is fixed to the end of the lifting rod 508 away from the cleaning rod.

[0035] Furthermore, after one end of the aluminum sheet passes through the limiting box 3, the cleaning plate 502 is driven by pulling the handle 509 to slide downward through the compression spring 504. Then, the cleaning plate 502 drives the brush 506 to clean the surface of the aluminum sheet, and the detection box 1 detects the surface of the aluminum sheet that has entered its interior.

[0036] Working principle: When aluminum sheets are placed on conveyor belt 7 for conveying, the connecting plate 405 is driven to slide by starting the electric push rod 406. Then the connecting plate 405 drives the adjusting plate 404 to slide, which in turn drives the sliding column 403 to slide in the inclined slide groove 407. This causes the limiting plate 402 to be centered and limited on the limiting rod 401 according to the size of the aluminum sheet. After one end of the aluminum sheet passes the limiting box 3, the cleaning plate 502 is driven to slide downward by pulling the handle 509 through the compression spring 504. Then the cleaning plate 502 drives the bristles 506 to clean the surface of the aluminum sheet. The detection box 1 detects the surface of the aluminum sheet that enters it.
