Description

Technical Field

[0001] The present invention relates to the technical field of steel plate detection, and particularly to a device and method for assisting manual visual surface detection. Background Art

[0002] At present, the detection methods for the surface quality of medium and heavy plates in industry mainly rely on manual visual inspection and traditional physical contact detection methods. Although the manual visual inspection method is simple to operate and has a low cost, it has serious defects. Due to the subjective judgment and experience differences of the inspectors, it is difficult to ensure the consistency and accuracy of the detection results. At the same time, the long-term and high-intensity detection work is extremely likely to cause visual fatigue of the inspectors, thus greatly increasing the probability of missed inspection and misjudgment. Especially when facing large-scale production tasks, the low efficiency of manual detection becomes more prominent and it is difficult to meet the dual requirements of modern industry for production speed and quality.

[0003] Traditional physical contact detection methods, such as common probe detection, although can find some obvious surface defects, also expose many drawbacks in practical applications. The detection speed is slow and cannot meet the real-time detection requirements of fast production lines; during the detection process, the probe directly contacts the surface of the medium and heavy plate, inevitably causing scratches, abrasions and other damages to the surface of the plate, affecting the surface quality of the product, and for tiny defects hidden inside the plate or surface defects with irregular shapes, such detection methods are often difficult to accurately identify and locate.

Description of the Drawings

[0016] To more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0017] Figure 1 It is a schematic structural diagram of the device for assisting artificial vision surface detection provided by the present invention; Wherein: 1. Lighting assembly; 2. Gripper assembly; 3. Holding rod. Specific embodiments

[0018] To make the content of the present invention easier to be clearly understood, the following will further elaborate on the present invention in detail according to specific embodiments and in combination with the drawings.

[0019] Figure 1 It is a schematic structural diagram of the device for assisting artificial vision surface detection provided by the embodiments of the present application. The device includes a lighting assembly 1, a gripper assembly 2, and a holding rod 3.

[0020] Specifically, in this embodiment, the lighting assembly 1 includes a lighting flashlight made of aluminum alloy, with a length of 16.2 cm, an inner diameter of 30 mm, and a weight of 292 g. The aluminum alloy material has good heat dissipation and durability, which can ensure the stability of the flashlight during long-term use.

[0021] It should be noted that the flashlight needs to provide stable and concentrated light to illuminate the surface of the steel plate to be detected, making the surface defects of the steel plate easier to be discovered.

[0022] The gripper assembly 2 is detachably clamped on the outside of the lighting assembly 1. The gripper assembly 2 includes a first gripper jaw and a second gripper jaw arranged oppositely and an adjusting device for adjusting the distance between the first gripper jaw and the second gripper jaw. By making the first gripper jaw and the second gripper jaw located on both sides of the flashlight respectively, and then adjusting the distance between the first gripper jaw and the second gripper jaw through the adjusting device, the gripper assembly 2 can stably clamp the lighting assembly 1.

[0023] In this embodiment, the gripper assembly 2 adopts a thickened clamp made of ABS plastic with a weight of 100 g. The ABS plastic material is lightweight and has certain toughness and strength. The thickened design enhances its clamping stability, thereby ensuring the stability of the position of the lighting flashlight during the detection process.

[0024] The above-mentioned adjusting device adopts a threaded adjustment form, that is, the first gripper jaw and the second gripper jaw are respectively threadedly installed on two threaded sections of a bidirectional lead screw, and the first gripper jaw and the second gripper jaw are made to approach or move away from each other by rotating the bidirectional lead screw.

[0025] The grip rod 3 includes a metal hose. The metal hose is flexible and easy to shape, facilitating flexible adjustment by the inspection personnel according to different inspection positions and angles of the steel plate.

[0026] In this embodiment, two metal hoses with an inner diameter of 6 mm, a length of 48 cm, and a weight of 120 g are selected for the metal hose. One end of the two metal hoses is connected to each other, extending the operation distance and facilitating the inspection personnel to conduct a comprehensive inspection without directly contacting the steel plate.

[0027] This embodiment also provides a method for assisting manual visual surface inspection, which is based on the above-mentioned device for assisting manual visual surface inspection. The method specifically includes the following steps: Step S101: The inspection personnel hold one end of the grip rod 3 away from the lighting component 1.

[0028] Step S102: By adjusting the angle of the grip rod 3, adjust the position and lighting angle of the lighting component 1 so that the light irradiates the surface of the steel plate to be inspected at a preset angle.

[0029] Step S103: The inspection personnel observe whether there are defects on the surface of the steel plate.

[0030] Specifically, the inspection personnel hold one end of the metal hose, flexibly bend the metal hose to adjust the position and angle of the flashlight, turn on the flashlight, and make the light irradiate the surface of the medium-thick plate at an appropriate angle. The inspection personnel judge whether there are defects on the surface of the medium-thick plate by observing the distribution of the reflected light on the surface of the medium-thick plate and relying on phenomena such as the brightness change and abnormal reflection of the light. Due to the adjustability of the metal hose, the inspection personnel can comprehensively and carefully inspect each part of the medium-thick plate without directly contacting the medium-thick plate, improving the inspection efficiency and accuracy.

[0031] Therefore, the technical solution of this application has the advantages of simple operation, high inspection efficiency, and reduced work intensity of the inspection personnel, and can effectively meet the requirements for the surface quality inspection of medium-thick plates in industrial production.

[0032] In addition to the above embodiments, the present invention may also have other implementation manners; all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
