Description

Technical Field

[0001] This utility model relates to the field of defect detection technology for round bars, and particularly to a defect detection device for round bars. Background Technology

[0002] The defect detection device for round bars is a specialized device for the automated detection of surface or internal defects in round bars, such as metal bars and wood bars. Its core is to use a variety of technical means to quickly and accurately identify various defects that may occur in the production process of round bars, so as to ensure product quality, improve production efficiency and reduce manual inspection costs.

[0003] Metal parts processed from round bars are widely used in fields such as construction and machinery. After processing and cutting, round bars are generally transported using pallets. However, existing pallets are only flat and cannot limit the length of short round bars when cutting them. They can only hold a small number of round bars, which makes it easy for the round bars to fall during transport. The transport efficiency is also low, making them inconvenient to use.

[0004] The existing patent (publication number: CN218259291U) includes a pallet body. Corresponding connecting plates are fixedly connected to multiple sides of the upper surface of the pallet body. Two symmetrically arranged slots are opened on the inner side of the connecting plates, and lower partitions are rotatably connected within these slots. A pin is installed on one side of the upper inner wall of the lower partition, and a matching insertion hole is opened on the other side. This novel transfer pallet for processing and cutting round bars utilizes multiple lower partitions that are rotated to be perpendicular to the pallet body. Moving the pin on the upper pin of each lower partition allows the pin to be inserted into the slots on adjacent lower partitions, thus restricting the lower partitions. The lower partitions can shield shorter round bars, preventing them from falling during transport. This results in high transport efficiency. When not in use, the lower partitions can also be rotated, minimizing space requirements.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing defect detection devices for round bars typically involve placing the round bar directly on top of a platform and then using the detection device from above to detect defects. While this method can detect round bars, the detection range is limited, the efficiency is low, and no other effects can be achieved during the detection process, making it impractical.

[0006] Therefore, a defect detection device for round bars is proposed. Utility Model Content
