Description

Technical Field

[0001] This utility model relates to the field of surface defect detection of stamped parts, and in particular to a surface defect detection table for large stamped parts. Background Technology

[0002] Large stamped parts are widely used in automobile manufacturing, heavy machinery, aerospace and other fields. Their surface quality directly determines the structural strength, safety and appearance performance of the final product. Therefore, before leaving the factory, they must be rigorously inspected for defects such as surface cracks, dents, scratches, and burrs. Currently, the industry mainly relies on two methods for surface defect inspection of large stamped parts: one is manual visual inspection, and the other is automated inspection equipment based on industrial cameras. The mounting plates of industrial cameras in existing inspection equipment are mostly designed with a fixed height, which cannot be flexibly adjusted according to the thickness and size differences of large stamped parts. When inspecting stamped parts of different specifications, the distance between the camera and the workpiece surface cannot match the optimal detection focal length, resulting in insufficient image clarity, which in turn affects the judgment accuracy of the defect recognition algorithm, leading to "over-inspection" or "under-inspection" phenomena. To address this, a surface defect inspection platform for large stamped parts is proposed. Summary of the Invention

[0003] Therefore, it is necessary to provide a surface defect detection platform for large stamped parts to address the aforementioned technical problems.

[0004] To address the aforementioned technical problems, this utility model provides a solution by employing the following technical method: Existing industrial camera mounting plates in inspection equipment are mostly designed at a fixed height, making it impossible to flexibly adjust them according to the thickness and size differences of large stamped parts. When inspecting stamped parts of different specifications, the distance between the camera and the workpiece surface cannot match the optimal detection focal length, resulting in insufficient image clarity. This, in turn, affects the accuracy of the defect identification algorithm, leading to problems such as "over-inspection" or "under-inspection."

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A surface defect inspection station for large stamped parts includes: a conveyor belt; a mounting plate fixedly mounted on one side of the conveyor belt; an adjusting plate slidably mounted inside the mounting plate; a latching rod hinged to the outer side of the mounting plate and fastened to the inner wall of one side of the adjusting plate; a limiting structure for limiting the latching rod on one side of the mounting plate; a support plate fixedly mounted on one side of the adjusting plate; multiple mounting boxes slidably mounted on the top of the support plate; an industrial camera mounted inside each mounting box; fastening structures for adjusting and fixing the mounting boxes on both sides of each mounting box; and a reinforcing plate fixedly mounted on one side of the adjusting plate, with one side of the reinforcing plate fixedly connected to the support plate.

The T-shaped blocks are fixedly installed on one side of the mounting plate. A limiting plate is provided on one side of the mounting plate. The T-shaped blocks are slidably installed inside the limiting plate. A pull plate is fixedly provided on the top of the limiting plate.

[0008] As a preferred embodiment of the large stamping part surface defect detection platform provided by this utility model, a first sliding groove is provided inside one side of the limiting plate, and the size of the T-block is adapted to the first sliding groove.

[0009] As a preferred embodiment of the large stamping part surface defect detection platform provided by this utility model, the fastening structure includes two first side plates, which are respectively fixedly installed on both sides of the support plate. Second side plates are fixedly provided on both sides of the mounting box. Multiple T-bolts are slidably provided through the bottom of the first side plate, and the T-bolts slidably pass through the second side plate. A hand-tightening nut is threadedly connected to the outer side of the second side plate.

[0010] In a preferred embodiment of the large stamping part surface defect detection platform provided by this utility model, the second side plate has a through hole, and the T-bolt slides through the through hole.

[0011] In a preferred embodiment of the large stamping part surface defect detection table provided by this utility model, a second sliding groove is provided inside the first side plate, and the T-bolt slides through the second sliding groove.

[0012] In a preferred embodiment of the large stamping part surface defect detection table provided by this utility model, the cross section of the limiting plate is machined into an L shape, and one end of the limiting plate abuts against the outside of the buckle.
