Description

Technical Field

[0001] This utility model relates to the field of cleanliness testing, and more particularly to a surface cleanliness testing instrument in Taiwan. Background Technology

[0002] With increasingly fierce competition in the cold-rolled product market, users not only pay attention to the performance, surface quality, and shape of steel plates, but also put forward higher requirements for the surface cleanliness of steel plates. In the unit, the surface cleanliness of strip steel has become the most important factor besides performance, surface quality, and shape.

[0003] Existing surface cleanliness testing devices often operate during normal production line operation and high-speed strip movement. This method is highly dangerous, has low accuracy, and is difficult to statistically analyze. Furthermore, the testing targets are often multiple sections of a long strip, and the high-speed movement of the strip may lead to unclear test images. Since existing surface cleanliness testing instruments often lack the ability to fix the strip, they usually cannot perform more stable testing when the strip is in a fixed state. When the strip is too long, it is prone to loosening, which will seriously affect the testing results.

[0004] Therefore, those skilled in the art have provided on-stage surface cleanliness testing instruments to address the problems mentioned in the background section. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface cleanliness testing instrument. This device can quickly and stably fix the strip steel during testing, and only test the two sides of the head area of ​​a roll of strip steel, thereby improving testing stability, safety, and quality. At the same time, the device is simple to operate, reduces the number of operations required by the operator, and improves testing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface cleanliness testing instrument, including a desktop, a pressing mechanism provided at the rear of the upper end of the desktop, the pressing mechanism including a fixed platform, slider brackets fixedly provided on both sides of the fixed platform at the front and rear, a plurality of slider brackets having sliding blocks slidably disposed inside each slider bracket towards the fixed platform, a vertical rack block fixedly disposed at the lower end of the sliding block located inside the slider bracket near the fixed platform, a long gear rotatably disposed inside each slider bracket near the outer side of the vertical rack block, a rotating rod rotatably disposed inside the fixed platform at the front and rear ends, a first gear block fixedly sleeved around the rotating rod near the front and rear, a first rack rod slidably disposed inside the fixed platform near the upper side of the first gear block, a second rack rod slidably disposed inside the fixed platform near the lower side of the first gear block, and a second gear block fixedly sleeved around the rotating rod near the center;

[0007] An auxiliary mechanism is slidably disposed inside the clamping mechanism on the other side. The auxiliary mechanism includes an auxiliary block, and an auxiliary rack is fixedly disposed on one side of the auxiliary block near the bottom.

[0008] Furthermore, a slide rail bracket is fixedly installed on the upper end of the desktop near the pressing mechanism, an electric slide rail is installed on the upper end of the slide rail bracket, a detection body is slidably installed inside the electric slide rail, a strip steel is installed on the upper end of the pressing mechanism, and a main control device is fixedly installed on the upper end of the desktop near the front of the pressing mechanism.

[0009] Furthermore, the two No. 1 gear blocks are respectively located between the front and rear end slider supports, the two No. 1 rack rods are respectively located above the two No. 1 gear blocks on one side, and the two No. 2 rack rods are respectively located below the two No. 1 gear blocks on the other side. The rack portions at the lower ends of the two No. 1 rack rods and the No. 2 rack rods are meshed with the adjacent No. 1 gear blocks.

[0010] Furthermore, each of the long gears is meshed with an adjacent vertical rack block, and the outer rack portions at the lower ends of the two rack rods, No. 1 and No. 2, are meshed with the adjacent long gears.

[0011] Furthermore, the two rack rods, No. 1 and No. 2, extend from the inside of the fixed platform all the way to the outside of the adjacent slider bracket.

[0012] Furthermore, the auxiliary rack rod is located below the second gear block on the other side, and the auxiliary rack rod is meshed with the second gear block.

[0015] This utility model has the following beneficial effects:

[0016] 1. The surface cleanliness testing instrument proposed in this utility model allows the device to rotate the rotating rod counterclockwise before placing the strip steel for testing. At this time, the first gear block will drive the adjacent first rack rod and second rack rod to slide in the direction of the rotating rod, which will further drive the corresponding long gear to rotate, thereby causing the sliding blocks at each point to move downward in the slider bracket until the strip steel is pressed tightly, preventing it from loosening during the testing process, improving the testing quality, and the fixing method is simple, stable and easy to operate.

[0017] 2. The surface cleanliness testing instrument proposed in this utility model allows the testing body to continue moving to the other side after testing both sides. This movement pushes the auxiliary block to the other side, causing the auxiliary rack block to move and the rotating rod to rotate clockwise. This releases the clamping mechanism from the strip steel, allowing it to be quickly removed. In the overall testing process, this reduces the number of operations required by the testing personnel, lightens their workload, simplifies the testing process, and improves testing efficiency. Furthermore, for longer sections of strip steel, two points are tested, and real-time comparative image analysis is performed using a photographic analysis device. A single image allows for a better comparison and analysis of the acceptable cleanliness shown on the color chart with the actual tested cleanliness. The test results represent the quality of the entire section, with low risk and higher accuracy, facilitating subsequent statistical analysis. Attached Figure Description

[0025] 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.

[0026] Reference Figure 1 An embodiment of this utility model provides a surface cleanliness tester, including a desktop 2. A pressing mechanism 1 is provided at the rear of the upper end of the desktop 2. An auxiliary mechanism 8 is slidably provided through the pressing mechanism 1 on the other side. A slide rail bracket 7 is fixedly provided at the upper end of the desktop 2 near the pressing mechanism 1. An electric slide rail 6 is provided at the upper end of the slide rail bracket 7. A test body 4 is slidably provided inside the electric slide rail 6. A strip steel 5 is provided at the upper end of the pressing mechanism 1. A main control device 3 is fixedly provided at the upper end of the desktop 2 near the front of the pressing mechanism 1.

[0027] Specifically, when performing cleanliness testing on the surface of strip steel 5, the front end of a section of strip steel 5 can be placed on the clamping mechanism 1 and fixed by the clamping mechanism 1 to prevent shaking and bending, thereby improving the testing quality. The main control device 3 is used to control the operation of the testing equipment. The electric slide rail 6 runs stably on the slide rail bracket 7, driving the testing body 4 to move and perform testing on certain positions on both sides of the strip steel 5. After completing the testing on both sides, it continues to move to the other side. The auxiliary mechanism 8 can also be pushed out, which cooperates with the clamping device 1 to release the clamping on the strip steel 5. This simplifies the operation process, improves testing efficiency, and requires only one operation by the testing personnel, reducing workload.

[0028] Reference Figures 1 to 5 The clamping mechanism 1 includes a fixed platform 104. Slider brackets 101 are fixedly installed on both sides of the fixed platform 104 near the front and rear. Slider blocks 102 are slidably installed inside the multiple slider brackets 101 in the direction of the fixed platform 104. Vertical rack blocks 107 are fixedly installed at the lower end of the internal portion of the multiple sliding blocks 102 near the fixed platform 104. Long gears 108 are rotatably installed inside the multiple slider brackets 101 near the outer side of the vertical rack blocks 107. A rotating rod 105 is rotatably installed inside the fixed platform 104 near the front and rear ends. A first gear block 110 is fixedly fitted around the rotating rod 105 near the front and rear. A first rack rod 106 is slidably installed inside the fixed platform 104 near the upper side of the first gear block 110. A second rack rod 109 is slidably installed inside the fixed platform 104 near the lower side of the first gear block 110. A second gear block 111 is fixedly fitted around the rotating rod 105 near the center.

[0029] Two first gear blocks 110 are located between the front and rear slider supports 101 respectively. Two first rack rods 106 are located above the two first gear blocks 110 on one side respectively. Two second rack rods 109 are located below the two first gear blocks 110 on the other side respectively. The rack portions of the lower ends of the two first rack rods 106 and the second rack rods 109 are meshed with the adjacent first gear blocks 110. Multiple long gears 108 are meshed with the adjacent vertical rack blocks 107. The rack portions of the lower ends of the two first rack rods 106 and the second rack rods 109 are meshed with the adjacent long gears 108.

[0030] Two rack rods, No. 1 106 and No. 2 109, extend from the inside of the fixed platform 104 to the outside of the adjacent slider bracket 101. An auxiliary rack rod 802 is located below the No. 2 gear block 111 on the other side and meshes with the No. 2 gear block 111. Multiple sliding blocks 102 are located on the lower part of the outer side of the slider bracket 101 and are provided with pressing soft blocks 103. The multiple pressing soft blocks 103 are all made of silicone. The detection body 4 includes a shell 401. A shooting analysis device 402 is installed through the upper part of the shell 401. The shooting analysis device 402 is equipped with a supplementary light. A locking block 404 is slidably installed through the center of the front end of the shell 401. A color card 403 is provided on the upper end of the locking block 404. The detection body 4 can be raised and lowered.

[0031] Specifically, after the strip steel 5 is placed on the upper end of the fixed platform 104, the rotating rod 105 can be rotated counterclockwise. There is a large friction between the rotating rod 105 and the fixed platform 104. It will not rotate on its own without manual rotation. Instead, it will drive the adjacent first rack rod 106 and second rack rod 109 to slide towards the rotating rod 105 through the two first gear blocks 110 around its body. The sliding will drive each long gear 108 to rotate. The rotation of each long gear 108 can cause the adjacent sliding block 102 to move downward, thereby achieving the pressing of the strip steel 5. The silicone pressing soft block 103 will first contact the surface of the strip steel 5 to prevent scratches on the strip steel 5. The card block 403 can be pried out to replace the internal color card 403. After the photograph is taken by the photograph analysis device 402, a better comparative analysis can be performed with the product surface.

[0032] Reference Figure 1 and Figure 2 The auxiliary mechanism 8 includes an auxiliary block 801. An auxiliary rack rod 802 is fixedly installed on one side of the auxiliary block 801 near the bottom. The auxiliary rack rod 802 is located below the second gear block 111 on the other side. The auxiliary rack rod 802 is meshed with the second gear block 111.

[0033] Specifically, after the strip steel 5 is pressed, the electric slide rail 6 drives the detection body 4 to complete the detection work on both sides. After the detection is completed on the other side, it continues to move to the other side, which can push the auxiliary block 801 to move outward. The outward movement of the auxiliary block 801 can drive the rotating rod 105 to rotate clockwise, which can release the pressing of the strip steel 5 without the need for additional operation by the inspection personnel.

[0034] Working principle: When using this device, the front end of the strip steel 5 to be tested can be placed on the fixed platform 104. Then, the rotating rod 105 is rotated counterclockwise. The rotation of the rotating rod 105 causes the first rack rod 106 and the second rack rod 109, which are adjacent to the first gear block 110, to slide simultaneously towards the rotating rod 105. The sliding of the first rack rod 106 and the second rack rod 109 will drive the long gear 108 to rotate. The two long gears 108 on one side will rotate counterclockwise, and the two long gears 108 on the other side will rotate clockwise. The rotation of multiple long gears 108 will drive the adjacent sliding block 102 to slide. The strip 5 slides downward inside the support 101 until multiple clamping blocks 103 clamp the strip 5. At this time, the electric slide rail 6 will drive the detection body 4 to continue the detection work on both sides. First, the detection body 4 will start to move down after reaching the designated position. When its lower end contacts the surface of the strip, the internal imaging and analysis device 402 starts to work. It can take a picture of the standard qualified cleanliness shown on the color card 403 and the actual detected cleanliness on one picture, which can be compared and analyzed more intuitively. After the detection work is completed on one side, the detection body 4 rises and moves to another point and falls down to repeat the detection. Two points are taken for sampling and testing, which can represent the cleanliness status of this section of strip.

[0035] Secondly, after the inspection work on both sides is completed, the inspection body 4 will continue to move to the other side. The inspection body 4 will contact the auxiliary block 801 and push it to the other side. The movement of the auxiliary block 801 to the other side will drive the rotating rod 105 to rotate clockwise through the auxiliary rack rod 802. At this time, the pressure on the strip steel 5 will be released, and the strip steel 5 can be quickly removed.

[0036] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
