Description

Technical Field

[0001] This utility model relates to a surface defect detector for metal plates. Background Technology

[0002] Sheet metal refers to flat, rectangular building material panels made to standard sizes. It is used in the construction industry as components for walls, ceilings, or floors, and often refers to metal sheets that are forged, rolled, or cast.

[0003] Traditional metal sheet inspection typically involves a reciprocating inspection device that scans and processes data on the sheet surface. However, due to the varying sizes of the sheets, smaller sheets cannot be inspected simultaneously, leaving some areas undetected. These undetected areas are small and require manual repositioning and re-inspection, significantly wasting time on these smaller areas. This not only increases inspection time and efficiency but also increases the workload of manual repositioning and installation, leading to increased labor intensity and a more cumbersome process. Utility Model Content

[0004] This invention addresses the problem that traditional testing devices cannot inspect the entire surface of a plate at once, leaving some areas undetected. These undetected areas are often small and require manual repositioning and re-inspection, resulting in significant time wastage. This not only increases testing time and efficiency but also increases the workload of manual re-installation and placement, intensifying worker fatigue and adding to the complexity of the process. Therefore, this invention provides a metal plate surface defect detector.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a surface defect detector for metal plates, including a base and a detection box, wherein the detection box is fixedly installed on one side of the top of the base, and further includes:

[0017] Preferably, the dust collector hood has a through opening inside, and the air nozzle is installed obliquely at the top and bottom of the inner wall of the dust collector hood.

[0020] In this technical solution, by starting the motor, the motor drives the first toothed pulley to rotate, and the first toothed pulley drives the two second toothed pulleys to rotate through the transmission toothed belt.

[0021] Preferably, the adjustment assembly further includes a lead screw, a movable seat, and a guide rod. The lead screw is rotatably connected to the inside of the detection box, the guide rod is fixedly connected between the upright plate and the detection box, and the movable seat is threadedly connected to the lead screw.

[0022] In this technical solution, the second toothed pulley drives the lead screw to rotate, and the lead screw drives the threaded movable seat to move along the guide rod.

The groove is formed inside both ends of the second clamping plate, and the anti-slip pad is installed on the outer wall of one end of the first and second clamping plates.

[0028] In this technical solution, the metal plate to be tested is placed between two first clamping plates inside the placement seat. The first cylinder is activated, and the first cylinder pushes the first clamping plates to slide along the groove and lowers the plate at both ends under the action of the anti-slip pad, thereby fixing the plate inside the placement seat, which facilitates the quick fixing of plates of different sizes.

[0029] Preferably, the two ends of the first clamping plate are slidably connected to the grooves inside one end of the two second clamping plates, and both the first clamping plate and the second clamping plate are located inside the placement seat.

[0030] In this technical solution, when the plate moves between the two detectors in the testing box, the detectors quickly detect defects on the top and bottom surfaces of the plate, as well as the two end faces away from the second clamping plate. Then, the second cylinder is activated, which pushes the second clamping plate to clamp the plate. The first cylinder drives the first clamping plate to release the plate and move it away from the two end faces of the plate.

The movable seat 77 moves the placement seat 8 towards the dust collection hood 53. When the placement seat 8 moves the metal plate... When the plate is moved into the dust removal hood 53, the air pump 51 is started. The air pump 51 drives air to be delivered to the inner cavity 54 through the delivery pipe 52.
