Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of strip processing equipment, in particular to a strip edge detection device. Background Art
[0002] A strip is a narrow and long steel plate produced by various rolling enterprises to meet the needs of different industrial departments for industrial production of various metal or mechanical products. During the rolling process of the strip, affected by various factors such as raw materials, processes, and operation controls, cracks are extremely likely to appear at the edges of the strip. Once the strip has edge cracking, it will not only affect the quality of the strip itself, but also cause damage to the equipment for subsequent coiling operations of the strip. Therefore, on the conveying unit of the strip, a strip edge cracking detection device is generally set up. During the conveying process of the strip, the edges of the strip will be monitored in real time. Once an unqualified crack appears, the system will issue an alarm and record it. However, the positions of existing detection devices are generally fixed and cannot be changed according to different strip specifications, which limits their detection work. Sometimes, multiple sets of detection devices even need to be set up, and then according to different strip specifications, the corresponding detection devices are selectively activated, which undoubtedly increases the equipment investment. Summary of the Utility Model
[0003] The purpose of the utility model is to avoid the deficiencies of the prior art and provide a strip edge detection device, thereby effectively solving the deficiencies existing in the prior art.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a strip edge detection device, including a conveying mechanism and a light-shielding cover arranged above the conveying mechanism. Avoidance openings for the strip to pass through are arranged on the front and rear baffles of the light-shielding cover. Movable seats that can be synchronously adjusted are arranged on both sides above the light-shielding cover. An edge cracking detector is arranged below the movable seat, and the probes of the edge cracking detector face downwards towards the two sides of the strip respectively;
[0005] A positive and negative lead screw is arranged on the top of the light-shielding cover, and the positive and negative lead screw is driven to rotate by a servo motor. The movable seats are arranged on both sides with opposite thread directions of the positive and negative lead screw. Sensors for controlling the shutdown of the servo motor are also arranged on both sides of any one of the movable seats.
[0006] Further, threaded holes adapted to the threads on both sides of the positive and negative lead screw are respectively arranged on the two movable seats, and the movable seats are screwed on both sides with opposite thread directions of the positive and negative lead screw.
[0007] Further, a sliding rod is arranged at a position corresponding to the positive and negative lead screw inside the light-shielding cover, and a sliding block is arranged on the top of the movable seat. The sliding block is slidably installed on the sliding rod.
[0008] Furthermore, backlights are arranged at positions on both sides of the light-shielding cover corresponding to the lower part of the edge crack detector.
[0009] Furthermore, the edge crack detector is a vision camera.
[0010] Furthermore, the inductor is a travel switch, and the sensing ends of the two travel switches on both sides extend outwardly towards the outer side of the movable seat respectively.
[0011] Furthermore, the conveying mechanism includes a frame, and a plurality of conveying rollers are evenly arranged between the frames, and the light-shielding cover is installed on the top of the frame.
[0012] The above technical solution of the present utility model has the following beneficial effects: By driving two symmetrical movable seats to synchronously adjust their positions through a positive and negative lead screw, and arranging edge crack detectors on both sides of the movable seats, the positions of the edge crack detectors can be adjusted according to the width of the strip steel, so that it can not only adapt to the detection of the edges of strip steels of different specifications, but also reduce the equipment investment. In addition, the arrangement of the inductor on one side of the movable seat can ensure the safe operation of the two movable seats on both sides and avoid equipment collision caused by the misoperation of the servo motor. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a front view plane schematic diagram of an embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0015] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.
[0016] As Figure 1 shown, the edge detection device for strip steel in this embodiment includes a conveying mechanism 1 and a light-shielding cover 2 arranged above the conveying mechanism 1. The light-shielding cover 2 can block the scattered light from the outside, so as to ensure that the edge crack detector 5 can clearly capture the edge crack condition of the strip steel 3. Avoidance openings 2b for the passage of the strip steel 3 are provided on the front and rear baffles 2a of the light-shielding cover 2. Movable seats 4 that can be synchronously adjusted are arranged on both sides above the light-shielding cover 2. An edge crack detector 5 is arranged below the movable seat 4, and the probes of the edge crack detector 5 face downwards towards the two side edges of the strip steel 3 respectively;
[0017] A lead screw 6 is arranged at the top of the light-shielding cover 2. The lead screw 6 is horizontally placed inside the light-shielding cover 2 and is driven to rotate by a servo motor 7. The movable seats 4 are respectively arranged on both sides of the lead screw 6 with opposite thread directions. Sensors 8 for controlling the shutdown of the servo motor 7 are also arranged on both sides of any one of the movable seats 4.
[0018] Threaded holes adapted to the threads on both sides of the lead screw 6 are respectively arranged on the two movable seats 4 on both sides. The movable seats 4 are screwed on both sides of the lead screw 6 with opposite thread directions. When the servo motor 7 drives the lead screw 6 to rotate, the two movable seats 4 on both sides can move towards the center simultaneously, or move away from each other towards both sides synchronously.
[0019] A slide bar 9 is arranged inside the light-shielding cover 2 at a position corresponding to the upper part of the lead screw 5. A slider 10 is arranged at the top of the movable seat 4. The slider 10 is slidably installed on the slide bar 9, and the slide bar 9 plays a role in fixation and guiding.
[0020] Backlights 11 are arranged on both sides of the light-shielding cover 2 at positions corresponding to the lower part of the edge crack detector 5.
[0021] Preferably, the edge crack detector 5 is a vision camera, and the lens of the vision camera faces the two side edges of the strip steel 3.
[0022] Preferably, the sensor 8 is a travel switch. The sensing ends of the two travel switches 8 on both sides respectively extend towards the outside of the movable seat 4. The two movable seats 4 on both sides are controlled to move synchronously by the lead screw 6. Once a misoperation occurs in the control system, causing the lead screw 6 to be overly displaced, the sensor 8 on one movable seat 4 can come into contact with the side edge of the light-shielding cover 2 or the sensor 8 on the other movable seat 4, so that the sensor 8 sends a signal to control the servo motor 7 to stop, thereby preventing collisions between the movable seats 4 or between the movable seat 4 and the light-shielding cover 2, which may cause damage to the equipment.
[0023] The conveying mechanism 1 includes a frame 1a, and a plurality of conveying rollers 1b are evenly arranged between the frames 1a. The light-shielding cover 2 is installed on the top of the frame 1a.
[0024] The working principle of the present utility model is as follows: The strip steel is conveyed on the conveying roller 1b of the conveying mechanism 1. The strip steel 3 enters the interior of the light-shielding cover 2 at the avoidance opening 2b at the rear side of the light-shielding cover 2. By controlling the operation of the servo motor 7, the movement of the two side movable seats 4 is controlled, so that the edge crack detectors 5 on the movable seats 4 are aligned with the positions of the two sides of the strip steel 3. And at this time, the backlight 11 is also started. When the strip steel 3 is conveyed in the light-shielding cover 2, the edge crack detectors 5 take pictures of the side of the strip steel 3 and perform data analysis, so that the situation of the edge of the strip steel 3 is displayed in the background system in the form of curvature distribution. The system can judge the situation of the edge cracks on both sides of the strip steel 3 according to the curvature situation. Finally, the strip steel 3 will be sent out at the avoidance opening 2b of the front baffle 2a.
[0025] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.
