[0003] The length of the steel plate is an important quality indicator of the steel plate. In the actual production of steel plates, contact measurement or laser Doppler velocimeter is often used to achieve length control during the steel plate shearing process.

DETAILED DESCRIPTION

[0027] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of devices and methods consistent with some aspects of the present application as detailed in the claims.

[0028] The length of a steel plate is an important indicator of its quality, so length control means are required during the steel plate shearing process. However, traditional length control means, such as contact measurement and laser Doppler velocimeter measurement, will cause measurement errors due to the pause, vibration, reversal, and temperature changes of the measured steel plate. Length measurement errors will lead to a decrease in the yield of the steel plate. Therefore, this application proposes an automatic length re-inspection system for steel plate shearing to solve the problem of inaccurate length measurement during steel plate shearing.

[0029] See also Figure 1 , is a schematic diagram of the structure of an automatic length recheck system for steel plate shearing in this application. Figure 1 As shown, the steel plate shearing automatic length re-inspection system provided by the present application includes a support mechanism 1, a guide rail slide mechanism 2, a displacement measurement module 3, a position detection module 4 and a control module 5, wherein the support mechanism 1 is arranged on one side of the roller conveyor of the shearing device. The guide rail slide mechanism 2 includes a linear guide rail 21 and a slide 22, wherein the linear guide rail 21 is arranged on the support mechanism 1 in a direction parallel to the roller conveyor, and the slide 22 is a rectangular block structure with a groove, wherein the slide 22 is movably connected to the linear guide rail 21 through the groove, and the slide 22 is electrically connected to the control module 5.

[0030] The support mechanism 1 can play the role of arranging the position of the system. The support mechanism 1 is arranged on one side of the outlet roller of the shearing equipment, that is, the support mechanism 1 can be arranged on the left or right side of the outlet roller during installation. The specific installation on the left or right side needs to be selected according to the environment on both sides of the outlet roller, and there is no restriction in this application. The role of the linear guide 21 designed to be parallel to the outlet roller is to enable the linear guide 21 to have a corresponding relationship with the length of the steel plate. The slide 22 is a slider installed on the linear guide 21, and various detection equipment is arranged on the slide 22 to obtain the length of the steel plate. The control module 5 can control the slide 22 to slide along the linear guide 21.

[0031] The displacement measurement module 3 is arranged on the linear guide rail 21, and the displacement measurement module 3 is electrically connected to the control module 5. The position detection module 4 includes a laser detection probe 41, and the laser detection probe 41 is arranged on the slide 22, and the laser detection probe 41 faces the steel outlet roller table, and the laser detection probe 41 is electrically connected to the control module 5.

[0032] The control module 5 can control the displacement measurement module 3 to record the displacement of the slide 22 and obtain the position of the slide 22 on the linear guide 21. The laser detection probe 41 in the position detection module 4 is located on the slide 22. The sliding of the slide 22 on the linear guide 21 will drive the position of the laser detection probe 41 to change. The displacement measurement module 3 can obtain the position information of the slide 22, thereby obtaining the position information of the laser detection probe 41. The laser detection probe 41 can detect the object information at the measured position of the steel outlet roller and send the detected information to the control module 5. The accurate length of the steel plate can be obtained through the position information of the laser detection probe 41 and the distance from the starting end of the linear guide 21 to the steel outlet.

[0033] Because the laser detection probe 41 can emit lasers of a certain width, when the steel plate at the outlet reaches the detection position of the laser detection probe 41, the laser detection probe 41 will upload the information to the control module 5. The control module 5 communicates with the controller of the steel plate shearing equipment to send out the length information of the steel plate, guides the controller of the shearing equipment to perform the steel plate shearing action, and realizes accurate measurement and control of the length of the steel plate.

[0034] like Figure 1As shown, the support mechanism 1 includes a plurality of columns 11, support channel steels 12 and support angle steels 13, wherein the plurality of columns 11 are fixed to the ground on one side of the steel outlet roller along a direction parallel to the steel outlet roller, and the columns 11 are perpendicular to the ground; the support channel steels 12 are arranged between adjacent columns 11, and the linear guide rails 21 are arranged on the support channel steels 12; the support angle steels 13 are arranged between adjacent columns 11, and the support angle steels 13 are placed parallel to the support channel steels 12.

[0035] The number of the columns 11 can be set according to the length range of the steel plate to be cut, and the specific number is not limited in this application. The multiple columns 11 can be placed equidistantly or unequally, and the specific placement spacing is not limited in this application. However, in some embodiments of the present application, considering the weight of the support channel steel 12 and the support angle steel 13 arranged between adjacent columns 11, in order to avoid large elastic deformation, the spacing between the columns 11 should not be greater than 4m.

[0036] It should be noted that the structures of the columns 11 are the same, and during installation, the height of each column 11 should be kept consistent, with a height error of no more than 2 mm. The setting direction of the columns 11 is parallel to the outlet roller, and the left and right straightness error of each column 11 is no more than 2 mm.

[0037] The supporting channel steel 12 is used to carry the linear guide rail 21. When the length range of the sheared steel plate is large, multiple columns 11 can be set. At the same time, the supporting channel steel 12 is divided into multiple sections and fixed between adjacent columns 11. The horizontality error between the supporting channel steels 12 in different sections is not more than 2 mm.

[0038] In some embodiments of the present application, the support channel steel 12 has fixing holes arranged equidistantly, and the linear guide rail 21 also has fixing holes arranged equidistantly. The linear guide rail 21 can be fixed to the support channel steel 12 by connecting the fixing holes on the support channel steel 12 and the linear guide rail 21 with bolts or rivets.

[0039] See also Figure 2 , is a schematic diagram of the structure of a column in an embodiment of the present application. Figure 2As shown, the column 11 includes a column 111, a first support plate 112, a second support plate 113 and a connecting plate 114, wherein the column 111 is a cylindrical structure, the column 111 includes a bottom and a top, the bottom of the column 111 is connected to the connecting plate 114 by bolts; the connecting plate 114 is a square sheet structure, a plurality of threaded connection holes are distributed on the connecting plate 114, and the connecting plate 114 connects the column 111 vertically to the ground through the threaded connection holes; the first support plate 112 is fixed to the top of the column 111, the first support plate 112 is parallel to the ground and perpendicular to the direction of the steel outlet roller; the support channel steel 12 is connected to the first support plate 112; the second support plate 113 is fixed between the bottom of the column 111 and the first support plate 112, the second support plate 113 is parallel to the first support plate 112; the support angle steel 13 is connected to the second support plate 113.

[0040] The first support plate 112 is used to connect the support channel steel 12, so as to fix the support channel steel 12 between the adjacent columns 11. The second support plate 113 is used to connect the support angle steel 13, so as to fix the support angle steel 13 between the adjacent columns 11. It should be noted that the connection between the support channel steel 12 and the first support plate 112 and the connection between the support angle steel 13 and the second support plate 113 can be achieved by threaded connection. At the same time, since the support channel steel 12 has a horizontal limit, the horizontality of the support channel steel 12 can be adjusted by bolt washers during connection.

[0041] See also Figure 5 , is a schematic diagram of the structure of a connection plate in an embodiment of the present application. Figure 5 As shown, the connecting plate 114 includes a plurality of threaded connection holes, and the connecting plate 114 plays the role of fixing the column 11 to the ground on one side of the roller. In some embodiments of the present application, the threaded connection holes are divided into column connection holes and ground connection holes, and there are 4 column connection holes, and the column connection holes are used to connect with the column 111 by bolts. The side of the connecting plate 114 close to the steel outlet roller is the front side, and the side away from the steel outlet roller is the rear side and the left and right sides. The column connection holes are located on the front side of the connecting plate 114. In order to ensure the connection strength between the column 11 and the ground, the number of the ground connection holes is large. Specifically, there are at least 4 ground connection holes on the left and right sides of the connecting plate 114, and there are at least 5 ground connection holes evenly arranged at equal distances on the rear side of the connecting plate 114, that is, the number of the ground connection holes is at least 13. At the same time, in order to ensure the fixing strength, the connecting plate 114 has a certain thickness. For example, in some embodiments, the thickness of the connecting plate 114 is 20 mm.

[0042] like Figure 5 As shown, in this embodiment, there are 9 ground connection holes on the left and right sides of the connection plate 114, and there are 10 ground connection holes evenly arranged at equal intervals on the back side of the connection plate 114. It is worth noting that the bolt length specifications used in the column connection hole and the ground connection hole are different. The bolts used in the column connection hole have the same diameter as the bolts used in the ground connection hole, and the length of the bolts used in the column connection hole is shorter than the bolts used in the ground connection hole. At the same time, in order to better fix to the ground, the ground connection hole can use expansion bolts. For example, the bolts used in the column connection hole can be fixed bolts with a diameter of 12 mm and a length of 50 mm, and the bolts used in the ground connection hole can be expansion bolts with a diameter of 12 mm and a length of 200 mm.

[0043] The guide rail slide mechanism 2 also includes a drag chain slot 23, which is fixed on the support angle steel 13 and is parallel to the linear guide rail 21. The drag chain slot 23 is used to hold the cables connecting the control module 5 with various components, so as to prevent the connection cables between the slide 22 and the control module 5 from being scratched or entangled when the slide 22 is running.

[0044] like Figure 3 As shown, the guide rail slide mechanism 2 also includes a servo motor 24, which is connected to the slide 22, and the servo motor 24 is electrically connected to the control module 5; the control module 5 is further configured to control the slide 22 to slide along the linear guide rail 21 through the servo motor 24.

[0045] The servo motor 24 can accurately control the movement distance of the slide 22 , and can accurately measure the displacement information of the slide 22 on the linear guide rail 21 in cooperation with the displacement measurement module 3 .

[0046] In some embodiments of the present application, Figure 4 As shown, the displacement measurement module 3 includes a laser emitting end 31 and a laser receiving end 32, wherein the laser emitting end 31 is arranged at both ends of the linear guide rail 21, and the laser receiving end 32 is arranged on the slide 22, and the laser emitting end 31 and the laser receiving end 32 are arranged opposite to each other and in the same line.

[0047] The laser emitting end 31 and the laser receiving end 32 can determine the distance between each other by sending and receiving lasers, thereby obtaining the displacement of the slide 22 on the linear guide rail 21. The laser receiving end 32 is arranged opposite to the laser emitting end 31 and in a colinear manner, which can ensure that the laser receiving end 32 can stably receive the laser emitted by the laser emitting end 31. The purpose of arranging the laser emitting end 31 at both ends of the linear guide rail 21 is to make the distance measurement result more accurate.

[0048] In some embodiments, only one laser emitting end 31 may be provided, and the laser emitting end 31 may be provided at any one of the two ends of the linear guide rail 21 , and the laser receiving end 32 is still provided opposite to and colinear with the laser emitting end 31 .

[0049] In some embodiments of the present application, Figure 3 As shown, the position detection module 4 also includes a fixing member 42, one end of which is connected to the slide 22, and the other end is connected to the laser detection probe 41. The fixing member 42 can limit the orientation and detection angle of the laser detection probe 41, so that the laser detection probe 41 can detect more comprehensively. The end of the fixing member 42 connected to the slide 22 can be connected by welding or threaded connection. In some embodiments, the end of the fixing member 42 connected to the laser detection probe 41 is a movable connection, and the laser detection probe 41 can rotate a certain angle relative to the fixing member 42, so that the detection range of the laser detection probe 41 covers the measured position of the steel outlet roller.

[0050] like Figure 6 As shown, the control module 5 includes a measurement and control host 51 and a human-machine interaction component 52, and the human-machine interaction component 52 is connected to the measurement and control host 51; the measurement and control host 51 is used to respond to control instructions to operate the guide rail slide mechanism 2, the displacement measurement module 3 and the position detection module 4, and receive information collected by the displacement measurement module 3 and the position detection module 4. The human-machine interaction component 52 is used to receive control instructions and send them to the measurement and control host 51.

[0051] In some embodiments of the present application, the measurement and control host 51 is connected to the controller of the shearing device. When the measurement and control host detects that the steel plate reaches the specified position, it will send information to the controller of the shearing device to provide a length basis for cutting the steel plate.

[0052] The control module 5 further includes a switch 53, which is connected to the measurement and control host 51; the measurement and control host 51 can also upload the collected information to the local area network through the switch 53. By uploading the data and summarizing the length information of the steel plates that have been sheared, the quality of the steel plates that have been sheared can be roughly evaluated, thereby improving the yield rate of the steel plates.

[0053] In some embodiments of the present application, the system further includes a temperature measurement module 6, which is disposed on the slide 22 and connected to the measurement and control host 51; the measurement and control host 51 can obtain the temperature information of the steel plate on the outlet roller through the temperature measurement module 6. Because the temperature change of the steel plate will cause a certain degree of deformation of the steel plate, the temperature measurement module 6 can measure the temperature around the steel plate, and the temperature measurement module 6 can be an infrared temperature sensor probe. After measuring the temperature around the steel plate, the measurement and control host 51 can compare the temperature data with the built-in temperature correction range to provide a length correction amount for the steel plate to be sheared, so as to avoid inaccurate length measurement of the steel plate due to temperature influence.

[0054] It can be seen from the above technical scheme that the present application provides an automatic length re-inspection system for steel plate shearing, including a support mechanism 1, a guide rail and slide mechanism 2, a displacement measurement module 3, a position detection module 4 and a control module 5, wherein the support mechanism 1 is used to carry other components in the system, the guide rail and slide mechanism 2 includes a linear guide 21 and a slide 22, and the slide 22 is fixed with a laser detection probe 41 in the position detection module 4, and the control module 5 controls the slide 22 to slide on the linear guide 21, so that the laser detection probe 41 can detect the steel plate on the roller of the steel outlet of the shearing equipment, and then the position and displacement of the laser detection probe 41 can be obtained through the displacement measurement module 3 to achieve the measurement of the length of the steel plate. The system realizes the accurate measurement of the length of the sheared steel plate by real-time detection of the roller of the steel outlet of the shearing equipment and transmission of information.

The specific implementation methods provided above are only a few examples under the general concept of this application and do not constitute a limitation on the protection scope of this application. For those skilled in the art, any other implementation methods expanded based on the scheme of this application without creative work belong to the protection scope of this application.
