Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically to a surface detection auxiliary platform. Background Technology

[0002] In the galvanizing production line, the galvanizing and aluminum galvanizing lines can produce galvanized and aluminum galvanized steel strips with a thickness of 0.38-3.5 mm. This product includes high-grade sheet products such as automotive outer panels. Customers have extremely high requirements for the surface quality of the sheet, and the surface roughness of the finished product needs to be tested for each coil produced each time.

[0003] The galvanizing production line operates at a high speed, with a daily production volume of more than 100 coils as different products are produced. During the process, the surface roughness of each coil needs to be measured to form a material card.

[0004] In the traditional inspection process, workers need to unwind the coiled steel strip and use a surface roughness testing instrument to inspect the surface roughness of the unwound steel strip. This unwinding, inspection, and rewinding inspection method is inefficient and time-consuming. To solve the above problems, workers will inspect the surface roughness of the steel strip on the production line. However, during the inspection process, the steel strip will bend and fall due to gravity, affecting the accuracy of surface roughness inspection. Utility Model Content

[0005] The purpose of this invention is to provide a surface inspection auxiliary platform to solve at least one of the above-mentioned technical problems.

[0006] The technical problem solved by this utility model can be achieved by the following technical solution:

[0007] A surface inspection auxiliary platform includes a frame body, wherein the long side of the frame body is aligned with the running direction of the strip steel;

[0008] Two operating plates for supporting the strip steel are fixed inside the frame body. The two operating plates are arranged opposite each other and their upper surfaces are flush. Vertical column supports are provided at the four corners of the lower surface of the frame body. Every two adjacent column supports are fixed to the operating plates.

[0009] The two operating plates are located on both sides of the frame body, and there is a gap between the two operating plates, which is called the detection gap. The width of the detection gap is greater than the width of the strip steel.

[0010] In the above design, the surface roughness detector for strip steel is placed in the detection gap position. This reduces the possibility of the detector interfering with the operation of the strip steel or damaging it by contact. The frame body, operating panel, and column support are integrated and arranged along the running direction of the strip steel, so that the operator can perform surface roughness detection on the strip steel during its operation. This eliminates the need to remove the coiled strip steel for surface roughness detection later, adapting to high-speed production cycles and achieving fast and accurate surface roughness detection, thereby improving product quality and production efficiency.

[0011] In a further optimization, the two operating plates are a first operating plate and a second operating plate, which are arranged along the running direction of the strip steel. A cleaning component for cleaning the strip steel that has moved onto the first operating plate is arranged on the first operating plate. A mounting frame is arranged at the position of the cleaning component, and the bottom end of the mounting frame is fixed to both sides of the frame body.

[0012] In the above design, a cleaning component is set up to clean the strip steel that will be subjected to surface roughness inspection during operation, without the need to stop the machine for cleaning, thus further improving the inspection efficiency.

[0013] In a further optimization, the cleaning assembly includes a connecting frame hinged to the side wall of the mounting frame. The connecting frame has a C-shaped cross-section. A connecting plate is fixed to the horizontal end of the connecting frame. The section of the connecting plate facing away from the connecting frame is an arc-shaped surface. A cleaning cloth is covered on the connecting plate. The cleaning cloth is connected to the connecting frame through the mounting assembly. An electric push rod is also hinged to the mounting frame. An ear seat is hinged to the extended end of the electric push rod. The ear seat is fixed to the connecting frame.

[0014] In the above design, power is provided by an electric push rod to drive the connecting frame to rotate, so that the cleaning cloth covering the connecting plate comes into contact with the surface of the strip steel to clean the strip steel during operation.

[0015] In a further optimization, the mounting assembly includes several evenly arranged circular holes on the connecting frame. Several rubber sheets are fixed to the inner wall of each circular hole. The combination of several rubber sheets covers the circular holes. A cleaning cloth covering the connecting plate extends to the position of the connecting frame and enters the several rubber sheets.

[0016] In the above design, when the cleaning cloth is inserted between several rubber sheets, the rubber sheets and the cleaning cloth form a friction pair, which facilitates the installation and removal of the cleaning cloth.

[0017] Further optimization involves making the connecting plate from a smooth metal material, including at least one of aluminum alloy and stainless steel.

[0018] In the above design, the connecting plate will not damage the cotton cloth, thus affecting the cleaning effect of the strip steel, nor will it scratch or damage the strip steel in operation.

[0019] In a further optimization, a transmission roller is provided on the lower surface of the mounting frame, and the outer surface of the transmission roller is covered with a polyurethane layer, which contacts the surface of the strip steel.

[0020] In the above design, the transmission rollers keep the strip running on the first operating plate flat, which facilitates cleaning and inspection.

[0021] In a further optimization, the mounting frame has T-shaped grooves on both sides. Guide posts fixed to the bottom and top walls of the grooves are installed in the grooves and are arranged vertically. A slider is fitted around the guide post and is slidably connected to it. The slider is fixed to the top wall of the groove by a spring fitted around the guide post. The slider extends out of the groove and is rotatably connected to the drive roller.

[0022] In the above design, the drive roller is made to elastically contact the surface of the strip steel by means of a spring, which can accommodate strip steel of different thicknesses.

[0023] In a further optimization, the bottom end of the column support is fixed with a support leg, and the bottom area of ​​the support leg is larger than the cross-sectional area of ​​the column support.

[0024] In the above design, by setting up support legs with a large bottom area, the overall stability of the device is improved, thereby improving the accuracy of strip surface roughness detection.

[0025] The beneficial effects of this application are as follows: the surface roughness testing instrument for strip steel is placed at the testing gap position, and the surface roughness of the strip steel located at the gap position is tested. This reduces the possibility of the testing instrument interfering with the operation of the strip steel or damaging the strip steel by contact. The frame body, operating panel and column support are integrated structures and arranged along the running direction of the strip steel, so that the operator can perform surface roughness testing on the strip steel during the running process. It is not necessary to remove the coiled strip steel for surface roughness testing later, which is suitable for high-speed production cycle, realizes fast and accurate surface roughness testing, and improves product quality and production efficiency.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0034] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0035] Reference Figures 1 to 3As shown, the preferred embodiment of this utility model provides a surface inspection auxiliary platform, including a frame body 1, the long side of which is aligned with the running direction of the strip steel; two operating plates for supporting the strip steel are fixed inside the frame body 1, the two operating plates are arranged opposite each other and their upper surfaces are flush; vertical column supports 2 are provided at the four corners of the lower surface of the frame body 1, and every two adjacent column supports 2 are fixed to the operating plates; the two operating plates are located on both sides of the frame body 1, and there is a gap between the two operating plates, called the inspection gap 3, the width of the inspection gap 3 being greater than the width of the strip steel.

[0036] In this embodiment, the surface roughness detector for the strip steel is positioned at the detection gap 3. Surface roughness is detected on the strip steel located in the gap, reducing the possibility of the detector interfering with the strip steel's operation or causing damage. The frame body 1, the operating panel, and the column support 2 are an integrated structure arranged along the strip steel's running direction, facilitating surface roughness detection by personnel during strip steel operation. This eliminates the need for subsequent removal of the coiled strip steel for surface roughness detection, adapting to high-speed production cycles and achieving rapid and accurate surface roughness detection, thereby improving product quality and production efficiency.

[0037] like Figure 1 and Figure 2 The system has two control panels, designated as a first control panel 4 and a second control panel 5, arranged along the strip's running direction. A cleaning assembly for cleaning the strip that has moved onto the first control panel 4 is mounted on the first control panel 4. A mounting frame 6 is positioned at the location of the cleaning assembly, with its bottom fixed to both sides of the frame body 1. The mounting frame 6 connects to the frame body 1 without interfering with the strip's operation. The mounting frame 6 supports the cleaning assembly, allowing for the cleaning of the strip before surface roughness testing during operation without requiring machine shutdown, thus further improving testing efficiency.

[0038] like Figure 1 and Figure 2 The cleaning assembly includes a connecting frame 7 hinged to the side wall of the mounting frame 6. The connecting frame 7 has a C-shaped cross-section, and a connecting plate 8 is fixed to the horizontal end of the connecting frame 7. The section of the connecting plate 8 facing away from the connecting frame 7 is an arc-shaped surface. A cleaning cloth is covered on the connecting plate 8, and the cleaning cloth is connected to the connecting frame 7 through the mounting assembly. An electric push rod 9 is also hinged to the mounting frame 6. The extended end of the electric push rod 9 is hinged to an ear seat, which is fixed to the connecting frame 7. Power is provided by the electric push rod 9 to drive the connecting frame 7 to rotate, so that the cleaning cloth covered on the connecting plate 8 comes into contact with the surface of the strip steel, cleaning the strip steel during operation, effectively removing oil and impurities from the strip steel surface, and leaving little dust after wiping, thus improving the accuracy of strip steel surface roughness detection.

[0039] like Figure 3The mounting assembly includes several evenly arranged circular holes 10 formed on the connecting frame 7. Several rubber sheets 11 are fixed to the inner wall of each circular hole 10. These rubber sheets 11 cover the circular holes 10. A cleaning cloth covering the connecting plate 8 extends to the connecting frame 7 and enters the rubber sheets 11. When the cleaning cloth is inserted between the rubber sheets 11, the rubber sheets 11 and the cleaning cloth form a friction pair, facilitating the installation and removal of the cleaning cloth.

[0040] The connecting plate 8 is made of a smooth metal material, including at least one of aluminum alloy and stainless steel. The connecting plate 8 will not damage the cotton cloth, affecting the cleaning effect of the strip steel, nor will it scratch or damage the strip steel in operation.

[0041] like Figure 1 and Figure 2 A drive roller 12 is provided on the lower surface of the mounting frame 6. The outer surface of the drive roller 12 is covered with a polyurethane layer, which contacts the surface of the strip steel. The drive roller 12 keeps the strip steel running on the first operating plate 4 flat, facilitating cleaning and inspection.

[0042] like Figure 1 and Figure 2 The mounting bracket 6 has T-shaped grooves 13 on both sides. Guide posts, vertically arranged, are fixed to the bottom and top walls of the grooves 13. A slider, slidably connected to the guide post, is fitted over the guide post. The slider is fixed to the top wall of the groove 13 by a spring fitted over the guide post. The slider extends out of the groove 13, and the portion extending out of the groove 13 is rotatably connected to the drive roller 12. The spring allows the drive roller 12 to elastically contact the strip surface, accommodating strips of different thicknesses. The rotatably connected drive roller 12 reduces sliding friction with the strip surface. The cooperation of the slider and guide posts guides and limits the movement of the slider.

[0043] like Figure 1 and Figure 2 The bottom end of the column support 2 is fixed with a support leg 14, the base area of ​​which is larger than the cross-sectional area of ​​the column support 2. By setting the support leg 14 with a larger base area, the overall stability of the device is improved, thereby improving the accuracy of strip surface roughness detection.

[0044] In use, the frame body 1, the first operating plate 4, the detection gap 3 and the second operating plate 5 are arranged along the running direction of the strip steel, and the detector for detecting the surface roughness of the strip steel is located at the detection gap 3.

[0045] During the operation of the strip steel, it passes through the frame body 1, the first operating plate 4, the detection gap 3 and the second operating plate 5 in sequence. The transmission roller 12 contacts the surface of the strip steel, so that the strip steel running on the first operating plate 4 remains flat.

[0046] Power is provided by the electric push rod 9, and the extended end of the electric push rod 9 extends to allow the cleaning cloth to contact the surface of the strip steel, cleaning the strip steel during operation, effectively removing oil and impurities from the surface of the strip steel, and wiping it away from leaving dust, thus improving the accuracy of strip steel surface roughness detection.

[0047] After the inspection is completed, the extended end of the electric push rod 9 moves in the opposite direction, causing the cleaning cloth to disconnect from the surface of the strip steel. The operator pulls the cleaning cloth out from the circular hole 10 and several rubber sheets 11, replaces it with a new cleaning cloth, and makes the cleaning cloth cover the outside of the connecting plate 8. The cleaning cloth extends to the position of the connecting frame 7 and is inserted between several rubber sheets 11. Several rubber sheets 11 and the cleaning cloth form a friction pair, which fixes the cleaning cloth to the connecting frame 7. The cleaning cloth is manually adjusted so that it covers the outside of the connecting plate 8 smoothly and without wrinkles, so as to facilitate the next inspection.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
