[0002] Wire mesh is a mesh material made of metal wire, plastic wire, or other fibers. It is commonly used in various applications such as screening, filtration, printing, and decoration. Metal wire mesh is a common industrial material, usually made of metal wire, and can be used for various applications such as filtration, screening, isolation, and reinforcement. The characteristics of metal wire mesh depend on the type of metal used, the mesh size, and the wire diameter. Common metal wire mesh materials include stainless steel, copper, aluminum, and alloys. Metal wire mesh is commonly used for screening and filtration in industrial fields, and can also be used in construction, artistic decoration, and other applications. After production, metal wire mesh usually needs to be inspected.

[0003] A search revealed Chinese patent publication number CN219831025U, which discloses a wire mesh inspection device. The device includes a housing with a wire mesh body positioned in the center. A cylinder is fixedly connected to the center of the top wall inside the housing. Support rods are fixedly connected to both sides of the cylinder's telescopic end. A fixed box is fixedly connected to the bottom of the support rods and the telescopic end of the cylinder. Telescopic columns are fixedly connected to both ends of the top of the fixed box, with their telescopic ends fixedly connected to the top wall inside the housing. A rocker arm is positioned in the center of the outer wall of the fixed box. This invention uses the interlocking of the rocker arm, gears, racks, and connecting rods to achieve left-right movement of the humidity detector, and the interlocking of the cylinder, support rods, and telescopic columns to achieve up-down movement of the humidity detector. This movement allows for changes in the humidity detector's position and height, thereby expanding the detection range of the wire mesh. However, in practical use, this device directly fixes the wire mesh for inspection without pre-treatment, which may result in foreign objects or dirt on the wire mesh surface affecting the detection results and causing a decrease in detection accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wire mesh inspection device, which aims to improve the problem that the absence of pretreatment of the wire mesh may lead to foreign objects or dirt on the wire mesh surface affecting the inspection results and thus causing a decrease in inspection accuracy.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figure 1 and Figure 2An embodiment of this utility model provides a wire mesh inspection device, including a workbench 1, a vertical plate 3 fixedly connected to the rear side of the top wall of the workbench 1, a hydraulic rod 4 fixedly connected to the top of the vertical plate 3, a servo motor 5 fixedly connected to the output end of the hydraulic rod 4, a turntable 6 fixedly connected to the output end of the servo motor 5, a cleaning shell 7 fixedly connected to the front side of the bottom wall of the turntable 6, a return spring 8 fixedly connected to the front and rear sides of the inner top wall of the cleaning shell 7, a mounting plate 9 fixedly connected to the bottom of the two return springs 8, threaded knobs 10 threaded through the front and rear sides of the top of the mounting plate 9, and a cleaning brush 11 threadedly connected to the bottom of the two threaded knobs 10, a detection device 13 fixedly connected to the rear side of the bottom wall of the turntable 6, a placement plate 19 fixedly connected to the middle of the top wall of the workbench 1, multiple through slots 20 equally spaced between the interior of the placement plate 19 and the interior of the workbench 1, a dust collection device 12 fixedly installed on the bottom wall of the workbench 1, a protective component provided on the right side of the detection device 13, and a fixing mechanism 2 provided on the front side of the vertical plate 3;

[0038] Specifically, by activating the hydraulic rod 4, the servo motor 5 at its output end moves downward together with the turntable 6. Once a suitable height is reached, the servo motor 5 is activated, driving the turntable 6 to rotate. The rotation of the turntable 6 drives the connected mounting plate 9 and cleaning brush 11. The main task of the cleaning brush 11 is to remove dirt and foreign objects from the surface of the wire mesh. The cleaning brush 11, through the elasticity of the return spring 8, can tightly adhere to the surface of the wire mesh and penetrate deep into its internal crevices for cleaning. In this way, even some hard-to-detect dirt and foreign objects on the surface of the wire mesh can be effectively removed by the cleaning brush 11, thereby reducing potential errors during subsequent inspection. While the cleaning brush 11 is cleaning, the vacuum cleaner 12 is also activated. The vacuum cleaner 12, with its powerful suction, extracts and sucks the dirt and foreign objects removed by the cleaning brush 11 through multiple channels 20. The wire mesh is inserted into the equipment, so that the dirt and foreign objects removed by the cleaning brush 11 can be uniformly processed, avoiding their pollution of the working environment. After the wire mesh is cleaned, the cross bar 15 is slid to the right to expose the detection device 13. The cross bar 15 is rotated forward and the locking plate 17 is flipped so that it engages with the locking groove 18 on the right side of the top wall of the turntable 6, thus fixing the protective shell 14 and preventing it from sliding during detection. The detection device 13 can then rotate with the turntable 6, thereby achieving comprehensive detection of the wire mesh. During the detection process, since the wire mesh has been cleaned, the dirt and foreign objects on its surface have been effectively removed, which allows the detection device 13 to more accurately read the state and data of the wire mesh, avoiding the influence of dirt and foreign objects on the detection results. At the same time, since the detection device 13 can perform continuous detection following the rotation of the turntable 6, the detection efficiency is greatly improved and the detection time is shortened.

[0039] Reference Figure 2The protective assembly includes a protective shell 14, the top of which is located on the right side of the bottom wall of the turntable 6. A cross rod 15 is rotatably connected to the top wall of the protective shell 14. A cross groove 16 is provided inside the turntable 6. The middle part of the cross rod 15 is slidably connected to the cross groove 16. Engaging grooves 18 are provided on the rear and left sides of the top wall of the turntable 6. An engaging plate 17 is rotatably connected to the top wall of the cross rod 15. The left end of the engaging plate 17 engages with the engaging groove 18.

[0040] Specifically, during cleaning, the cross bar 15 is slid to the left to shield the detection device 13 with the protective shell 14, and the locking plate 17 is flipped to engage with the locking groove 18 on the rear side of the top wall of the turntable 6, thus avoiding possible damage to the detection device 13 during cleaning. During testing, the cross bar 15 is slid to the right to expose the detection device 13, and the cross bar 15 is rotated forward and the locking plate 17 is flipped to engage with the locking groove 18 on the right side of the top wall of the turntable 6.

[0041] Reference Figure 1 and Figure 3 The fixing mechanism 2 includes a rotating page 201, the rear side of which is rotatably connected to the front side of the upright plate 3. A fixing ring 202 is fixedly connected to the front side of the rotating page 201. Rotating columns 203 are rotatably connected to the left and right sides of the fixing ring 202. Locking rings 204 are fixedly connected to the outer walls of the two rotating columns 203. Locking columns 205 are fixedly connected to the left and right sides of the top wall of the worktable 1. Locking grooves 206 are opened inside the two locking columns 205. The front ends of the two rotating columns 203 engage with the corresponding locking grooves 206.

[0042] Specifically, flipping the retaining ring 202 downwards ensures that the wire mesh is securely clamped between the retaining ring 202 and the placement plate 19. This design not only improves the stability of the clamping but also ensures the safety of the wire mesh during the inspection process. The clamping space between the retaining ring 202 and the placement plate 19 is moderate, neither causing excessive compression to the wire mesh nor effectively preventing the wire mesh from moving or shaking during the inspection process. Rotating the rotating column 203 allows the locking ring 204 to smoothly engage with the locking groove 206. The locking ring 204 and the locking groove 206 are ingeniously designed and tightly engaged, effectively preventing the wire mesh from shifting. This locking mechanism prevents the wire mesh from falling off or shifting during the inspection process. It also ensures that operators can easily clamp and inspect the wire mesh, greatly improving work efficiency. This not only avoids the damage that traditional clamps might cause to the wire mesh, but also enhances its protective effect. Traditional clamps often damage the wire mesh due to uneven clamping force or improper clamping methods, even affecting its performance. Because of its simple structure and easy operation, this mechanism can adapt to clamping and inspecting wire mesh of different specifications and types, achieving good clamping and protective effects for both large and small wire meshes.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A control switch 21 is fixedly connected to the left side of the upright plate 3. The control switch 21 is electrically connected to the hydraulic rod 4, the servo motor 5, the detection device 13 and the dust collection device 12 respectively. Support frames 23 are fixedly connected to the left and right sides of the bottom wall of the workbench 1. Corner pads 24 are fixedly connected to the front and rear sides of the bottom wall of the two support frames 23. A dustproof shell 22 is provided in the middle of the left side of the upright plate 3. The right side of the dustproof shell 22 is rotatably connected to the control switch 21 through a hinge.

[0044] Specifically, the control switch 21, which is electrically connected to the hydraulic rod 4, servo motor 5, detection device 13 and dust collection device 12 respectively, can turn the device on and off. The support frame 23 and corner protector 24 make the device more stable during operation. The dust cover 22 can protect the control switch 21 from dust.

[0045] Reference Figure 2 and Figure 3 A rubber ring 25 is fixedly connected to the middle of each of the two threaded knobs 10; a rubber pad 207 is fixedly connected to the bottom wall of the fixing ring 202.

[0046] Specifically, the rubber ring 25 reduces the rotational damage of the threaded knob 10 to the mounting plate 9, and the rubber pad 207 improves the fixing effect of the retaining ring 202.

[0047] Working principle: At the start of cleaning, the hydraulic rod 4 is activated, causing the servo motor 5 at its output end and the turntable 6 to move downwards together. Once a suitable height is reached, the servo motor 5 is activated again, driving the turntable 6. This, in turn, cleans the fixed mesh via the mounting plate 9 connected to the return spring 8 and the cleaning brush 11. Under the elastic force of the return spring 8, the cleaning brush 11 cleans the gaps inside the mesh, reducing errors during subsequent testing. The vacuum cleaner 12 is then activated, and the dirt and foreign objects cleaned by the cleaning brush 11 are extracted through multiple channels at a 20x speed and processed uniformly. During testing, the cross lever 15 is slid to the right to activate the testing device. 13 is exposed. The cross bar 15 is rotated forward and the locking plate 17 is flipped so that it engages with the locking groove 18 on the right side of the top wall of the turntable 6. Thus, the detection device 13 can follow the rotation of the turntable 6 to detect the wire mesh, ultimately avoiding the influence of dirt and foreign objects on the accuracy and results of the wire mesh detection, improving detection efficiency. The fixing ring 202 is flipped downward so that the wire mesh is clamped between the fixing ring 202 and the placement plate 19. The rotating column 203 is rotated so that the locking ring 204 engages with the locking groove 206, thereby completing the protection and fixation of the wire mesh. This allows the operator to easily clamp and detect the wire mesh, avoiding possible damage to the wire mesh caused by the fixing clamp, and improving the protection of the wire mesh.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
