Problems solved by technology

In the process of image acquisition, there are missing acquisitions. At the same time, image processing can only identify common roll marks, scratches, adhesions, etc., and there are misjudgments in the detection of indistinguishable approximate defects. Only through continuous learning can the system gradually improve the defects. recognition rate, while the system is expensive and not suitable for low-speed production lines

Embodiment 1

[0028] refer to Figure 1 ~ Figure 3 A strip surface horizontal inspection device shown includes a front inspection mechanism, a back inspection mechanism, an entrance idler 5, an exit idler 7, and an idler bracket; the front inspection mechanism is arranged on one side of the idler bracket; The back inspection mechanism is arranged in the idler bracket and its height is smaller than the idler bracket; the entrance idler 5 and the exit idler 7 are arranged in parallel and the upper surfaces of the two are at the same level, and the entrance idler 5 and the exit idler 7 are movably connected to the inlet side and the outlet side of the idler bracket respectively.

[0029] In the specific application, first place the strip 6 on the entrance idler 5 and the exit idler 7, and adjust the elevation of the entrance idler 5 and the exit idler 7 up and down based on the operating line of the unit, so that the entrance idler 5 It is at the same level as the upper surface of the exit id...

Embodiment 2

[0035] refer to figure 1 with figure 2 In the shown horizontal inspection device for the strip surface, on the basis of the first embodiment, the idler support includes a left support 8 and a right support 18 arranged in parallel; the left support 8 is connected with an exit idler 7. The entrance idler 5 is connected to the right support 18, and the exit idler 7 is parallel to the entrance idler 5; the back inspection mechanism is placed between the left support 8 and the right support 18.

[0036] In actual use, the idler bracket adopts this technical solution, which not only facilitates its supporting effect on the strip 6, but also facilitates the layout of the inspection mechanism on the back side.

Embodiment 3

[0038] refer to figure 2 A strip surface horizontal inspection device shown, on the basis of Embodiment 1 or Embodiment 2, also includes an operating side fence 9 and a transmission side fence 10 arranged in parallel; the operation side fence 9 and the transmission side fence 10 The two ends of the fence 10 are respectively fixedly connected to the top of the left bracket 8 and the right bracket 18 of the idler bracket, and the operation side fence 9 and the transmission side fence 10 are perpendicular to the entrance idler 5 and the exit idler 7 respectively.

[0039] In actual use, the connection of the left bracket 8 and the right bracket 18 can be realized by operating the side fence 9 and the transmission side fence 10, which can enhance its stability, and can also realize the safety protection effect on the observer when observing the surface quality of the strip 6 .

[0040] In specific application, the operation side fence 9 and the transmission side fence 10 can ado...

Abstract

The invention belongs to the technical field of plate and strip finishing and processing, and particularly relates to a horizontal plate and strip surface inspection device. The device comprises a front surface inspection mechanism, a back surface inspection mechanism, an inlet carrier roller, an outlet carrier roller and a carrier roller bracket, the front inspection mechanism is arranged on one side of the carrier roller bracket; the back surface inspection mechanism is arranged in the carrier roller bracket and is lower than the carrier roller bracket; the inlet carrier roller and the outlet carrier roller are arranged in parallel, the upper surfaces of the inlet carrier roller and the outlet carrier roller are located on the same horizontal plane, and the inlet carrier roller and the outlet carrier roller are movably connected to the inlet side and the outlet side of the carrier roller bracket respectively. During normal work, the belt material stays on the inlet carrier roller and the outlet carrier roller, so that the belt material is effectively prevented from overhanging, and the inspection result of the back surface is ensured. Through the arrangement of the front surface inspection mechanism and the back surface inspection mechanism, the surface quality of the front surface and the back surface of the plate strip can be inspected independently or simultaneously through human eye observation. The device is light in structure, high in practicability, high in cost performance and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of strip finishing and processing, and in particular relates to a horizontal inspection device for the strip surface. Background technique [0002] In the field of strip finishing and processing, such as strip coating unit, continuous heat treatment unit, strip hot-dip galvanizing unit, etc., these purgatory users have higher and higher requirements for the quality of the strip surface, and the surface quality has become the decisive strip product. An important indicator of price. Therefore, online surface inspection of the strip is very important. The surface detector system in the prior art is mainly composed of the following two processes: image acquisition and image processing. In the process of image acquisition, there are missing acquisitions. At the same time, image processing can only identify common roll marks, scratches, adhesions, etc., and there are misjudgments in the detection of indistinguis...
