Description
Technical Field
[0001] This invention relates to the field of strip steel camber measurement technology, and particularly to a double-sided following cold-rolled strip steel camber measurement device. Background Technology
[0002] During the measurement of strip steel camber, dust and particulate matter in the workshop environment easily adhere to the lens of the industrial camera, severely affecting image quality and leading to distortion in the extraction of strip steel edge contours, thus reducing the accuracy of camber measurement. To solve this problem, existing technologies often use glass plates to physically isolate core imaging components such as industrial cameras, thereby preventing dust intrusion at the source. However, during long-term use, a small amount of dust will still gradually accumulate on the surface of the glass plate. If not cleaned in time, this can easily form "secondary obstruction," which will also interfere with the camera's imaging effect, making it impossible to guarantee the continuity and accuracy of the measurement. Especially for bilateral measurement scenarios where the strip steel is moving, existing isolation and cleaning structures are difficult to adapt to the following movement requirements of the measuring device, easily leading to problems such as untimely cleaning, optical path interference, or mechanical interference. This limits the applicability of the measuring device in complex workshop environments and makes it difficult to meet the production requirements for high-precision, continuous measurement of strip steel camber.

A drive motor is fixedly installed at the lower end of the gantry frame. Gears are fixedly installed on the rotating shaft of the drive motor and one side of each set of threaded rods. Movable parts are threadedly connected to each set of threaded rods.
[0006] Preferably, the sewage discharge assembly includes a cavity shell fixedly installed at the lower end of the gantry frame, a connecting pipe fixedly installed at the rear end of the cavity shell at the lower side, a vacuum cleaner fixedly installed on the upper side of the connecting pipe, openings on both sides of the cavity shell, a U-shaped plate installed on the inner side of the cavity shell corresponding to the openings, a cleaning roller rotatably installed on the inner side of the U-shaped plate, round blocks fixedly installed on the front and rear sides of the rotating shaft of the cleaning roller, a protrusion fixedly installed on one side of each set of round blocks, an movable opening on the inner side of the movable part, and fixing blocks fixedly installed on the front and rear inner walls of the cavity shell.
[0007] Preferably, a fixing plate is fixedly installed at both the front and rear ends of the U-shaped plate, a universal joint is fixedly installed at the front end of the cleaning roller rotating shaft, a cylinder is fixedly installed at the front end of the universal joint, a slide rod is slidably installed on the inner side of the cylinder, a sleeve is fitted on both the front and rear sides of the cleaning roller rotating shaft, a direction rod is fixedly installed on the lower side of both sets of sleeves, a hemisphere is fixedly installed at the lower end of both sets of direction rods, a return spring is fitted between the outer hemisphere of the direction rod and the fixing plate, and a drive motor is fixedly installed at the front end of the fixing plate on the front side of the U-shaped plate.
[0008] Preferably, the linear servo motion module is equipped with an encoder, and the industrial camera controls the shooting by using the production line speed feedback from the encoder in real time.
[0009] Preferably, the two sides and the middle position of the fixed frame form a height difference, the outer side of the threaded rod is set with two opposite spiral patterns, the two sets of gears are meshed, and the moving parts are fixedly connected to the U-shaped plate.
[0010] Preferably, a ventilation hole is provided at one end of the cavity shell, and the cavity shell is connected to the connecting pipe and the interior of the vacuum cleaner. The vacuum cleaner is fixedly installed on the upper end of the measuring component. The opening allows the cleaning roller to move out. The U-shaped plate is sealed and fitted inside the opening. The protrusion will partially contact the fixed block as the cleaning roller rotates. The movable opening allows the cleaning roller's rotating shaft to move.
[0011] Preferably, the front end of the set of two fixed plates located on the front side of the U-shaped plate is set as a motor mounting base, the slide rod is fixedly connected to the rotating shaft of the second drive motor, a compression spring is set between the slide rod and the inner wall of the cylinder, the direction rod passes through the inside of the fixed plate, and the second drive motor is fixedly mounted on the front fixed plate motor mounting plate.
[0012] Compared with the prior art, the present invention has the following beneficial effects: The strip measurement area is illuminated by two sets of light sources, making it a bright area in the image. The industrial camera and light sources allow for the measurement of the strip edge position, which is not in the center of the field of view. The linear servo motion module controls the movement of the industrial camera, which always follows the movement of the strip edge. By using two sets of industrial cameras to distinguish and capture the edges of the two strips, each industrial camera only needs to cover a small area, and the actual length corresponding to a single pixel is small, thus resulting in high measurement accuracy. By starting the drive motor, the connected gears rotate, driving the meshing gears to simultaneously drive the connected threaded rods and synchronous pulleys. The synchronous belt, in conjunction with the engagement, drives another set of synchronous pulleys, causing the two sets of threaded rods to rotate synchronously. This drives the moving parts on both sides of the threaded connection to move away from or towards each other. The moving parts on both sides drive the two sets of cleaning rollers to move out of the cavity shell to clean the glass plate surface. During the movement, after passing the ramp position, the height difference on both sides of the fixed frame will lift the direction rod, allowing the cleaning rollers to effectively contact the glass plate surface and achieve effective cleaning. Rotational transmission is achieved through the sliding connection between the drive motor and the slide rod and the cylinder. The connection between the cylinder, the universal joint, and the cleaning roller, as well as the elasticity of the spring, pushes the universal joint towards the sleeve, effectively ensuring that the cleaning roller can rotate even when its height changes. When the hemisphere moves to the inclined position on the fixed frame, the directional rod and the sleeve will lift the cleaning roller, or the compressed return spring will pull the cleaning roller down, ensuring effective transmission even when the overall drive structure is not at the same horizontal height. When the cleaning assembly moves the U-shaped plates on both sides back into the two sets of openings, the vacuum cleaner is activated to remove dust from the cavity through the connecting pipe. Meanwhile, the drive motor drives the cleaning roller to rotate continuously. The rotating cleaning roller drives the round block and the protrusion to rotate. The rotating part of the protrusion contacts the fixed block, generating resistance that lifts the cleaning roller up and then moves away. Therefore, the continuous rotation of the round block, combined with the elastic pull of the return spring, makes the cleaning roller shake up and down, shaking off the surface residue, which is then sucked away by the vacuum cleaner. This achieves the self-cleaning function of the cleaning roller, extends the subsequent cleaning roller processing cycle, and efficiently achieves the cleaning work. Attached Figure Description

Detailed Implementation
[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0016] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship as a relative relationship of orientation or position, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
[0017] Please see Figures 1-9An embodiment of the present invention provides a bilateral following cold-rolled strip sickle bend measuring device, comprising a gantry frame 1, a strip steel sheet 2 disposed on the lower side of the gantry frame 1, a measuring component 3 disposed on the upper side of the gantry frame 1, a cleaning component 4 disposed near the middle position at the lower end of the gantry frame 1, and a sewage discharge component 5 disposed at the lower end of the gantry frame 1. The measuring component 3 includes a housing 31 fixedly disposed on the gantry frame 1, a linear servo motion module 32 fixedly disposed in the cavities on both sides of the housing 31, an industrial camera 33 fixedly disposed on the moving part of the linear servo motion module 32, and light sources 34 fixedly disposed at an angle on both sides of the moving part of the linear servo motion module 32. Two sets of glass plates 35 are fixedly disposed at the bottom of the housing 31.
[0018] An encoder is installed on the linear servo motion module 32, and the industrial camera 33 controls the shooting by using the production line speed fed back in real time by the encoder.
[0019] The measurement area of the steel strip 2 is bright in the image due to the illumination of the two sets of light sources 34. The industrial camera 33 and the light sources 34 can measure the position of the edge of the steel strip 2 that is not in the center of the field of view. The linear servo motion module 32 controls the movement of the industrial camera 33 to always follow the movement of the edge of the steel strip 2. The two sets of industrial cameras 33 distinguish and capture the edges of the two steel strips 2. Each industrial camera 33 only needs to cover a small area, and the actual length corresponding to a single pixel is small, so the measurement accuracy is high.
[0020] The cleaning component 4 includes two sets of fixed brackets 41 fixedly installed at the lower end of the gantry frame 1. The fixed brackets 41 have two ramps 42 near the middle position. Bearing seats 43 are fixedly installed on both sides of the lower end of the outer shell 31 near the fixed brackets 41. A threaded rod 44 is rotatably installed between the two sets of bearing seats 43. A synchronous pulley 45 is fixedly installed on one side of each set of threaded rods 44. A synchronous belt 46 is sleeved on the outer side of each set of synchronous pulleys 45. A drive motor 47 is fixedly installed at the lower end of the gantry frame 1. A gear 48 is fixedly installed on the rotating shaft of the drive motor 47 and one side of each set of threaded rods 44. Movable parts 49 are threadedly connected to each set of threaded rods 44.
[0021] The fixed frame 41 has a height difference between its two sides and the middle position. The outer side of the threaded rod 44 is set with two opposite spiral patterns. The two sets of gears 48 are meshed. The movable part 49 is fixedly connected to the U-shaped plate 55.
[0022] By starting the drive motor 47, the connected gear 48 is rotated. The meshing gear 48 simultaneously drives the connected threaded rod 44 and synchronous pulley 45. The synchronous belt 46, which is in conjunction with the synchronous belt, drives another set of synchronous pulleys 45, so that the two sets of threaded rods 44 rotate synchronously. This drives the movable parts 49 on both sides of the threaded connection to move away from or towards each other. The movable parts 49 on both sides drive the two sets of cleaning rollers 56 to move out of the cavity shell 51 to clean the surface of the glass plate 35. During the movement, after passing the position of the ramp 42, the height difference between the two sides of the fixed frame 41 will lift the direction rod 516, so that the cleaning rollers 56 can effectively contact the surface of the glass plate 35, thus achieving effective cleaning.
[0023] The sewage discharge assembly 5 includes a cavity shell 51 fixedly installed at the lower end of the gantry frame 1. A connecting pipe 52 is fixedly installed at the lower rear end of the cavity shell 51. A vacuum cleaner 53 is fixedly installed on the upper side of the connecting pipe 52. Openings 54 are provided on both sides of the cavity shell 51. A U-shaped plate 55 is provided on the inner side of the cavity shell 51 corresponding to the position of the opening 54. A cleaning roller 56 is rotatably installed on the inner side of the U-shaped plate 55. Round blocks 57 are fixedly installed on the front and rear sides of the rotating shaft of the cleaning roller 56. A protrusion 58 is fixedly installed on one side of each of the two sets of round blocks 57. An movable opening 59 is provided on the inner side of the movable part 49. Fixing blocks 510 are fixedly installed on the inner walls of the front and rear sides of the cavity shell 51.
[0024] A ventilation hole is provided at one end of the cavity shell 51. The cavity shell 51 is connected to the interior of the connecting pipe 52 and the vacuum cleaner 53. The vacuum cleaner 53 is fixedly installed on the upper end of the measuring component 3. The opening 54 allows the cleaning roller 56 to move out. The U-shaped plate 55 is sealed and fitted inside the opening 54. The protrusion 58 will partially contact the fixed block 510 as the cleaning roller 56 rotates. The movable port 59 allows the rotating shaft of the cleaning roller 56 to move.
[0025] When the cleaning component 4 moves the two U-shaped plates 55 back into the two sets of openings 54, the vacuum cleaner 53 is activated to perform dust extraction on the cavity shell 51 through the connecting pipe 52. Meanwhile, the drive motor 519 drives the cleaning roller 56 to rotate continuously. The rotating cleaning roller 56 drives the round block 57 and the protrusion 58 to rotate. The rotating part of the protrusion 58 contacts the fixed block 510, generating resistance that lifts the cleaning roller 56 before it rotates away. Therefore, the continuous rotation of the round block 57, combined with the elastic tension of the return spring 518, causes the cleaning roller 56 to shake up and down, shaking off the surface residue, which is then sucked away by the vacuum cleaner 53. This achieves the self-cleaning function of the cleaning roller 56, extends the subsequent processing cycle of the cleaning roller 56, and efficiently achieves the cleaning work.
[0026] The front and rear ends of the U-shaped plate 55 are fixedly equipped with fixing plates 511. The front end of the rotating shaft of the cleaning roller 56 is fixedly equipped with a universal joint 512. The front end of the universal joint 512 is fixedly equipped with a cylinder 513. The inner side of the cylinder 513 is slidably equipped with a slide rod 514. The front and rear sides of the rotating shaft of the cleaning roller 56 are both fitted with round sleeves 515. The lower side of the two sets of round sleeves 515 is fixedly equipped with a direction rod 516. The lower end of the two sets of direction rods 516 is fixedly equipped with a hemisphere 517. The outer hemisphere 517 of the direction rod 516 is fitted with a return spring 518 between it and the fixing plate 511. The front end of the front fixing plate 511 of the U-shaped plate 55 is fixedly equipped with a drive motor 519.
[0027] One of the two sets of fixing plates 511 is located at the front end of the U-shaped plate 55 and is set as a motor mounting base. The slide rod 514 is fixedly connected to the rotating shaft of the second drive motor 519. A compression spring is provided between the slide rod 514 and the inner wall of the cylinder 513. The direction rod 516 passes through the inside of the fixing plate 511. The second drive motor 519 is fixedly installed on the motor mounting plate of the front fixing plate 511.
[0028] The drive motor 519 drives the slide bar 514 to slide and connect with the cylinder 513 for rotational transmission. The connection between the cylinder 513, the universal joint 512 and the cleaning roller 56, as well as the elasticity of the spring, pushes the universal joint 512 towards the sleeve 515, effectively ensuring that the cleaning roller 56 can rotate even when its height changes. When the hemispherical ball 517 moves to the slope 42 position on the fixed frame 41, the direction rod 516 and the sleeve 515 will lift the cleaning roller 56, or the compressed return spring 518 will pull the cleaning roller 56 down, ensuring that the overall drive structure can effectively transmit power even when it is not at the same horizontal height.
[0029] Working principle: During use, the measurement area of the steel strip 2 is illuminated by two sets of light sources 34, making it a bright area in the image. The industrial camera 33 and the light sources 34 allow for the measurement of the edge of the steel strip 2, which is not in the center of the field of view. The linear servo motion module 32 controls the movement of the industrial camera 33, ensuring it always follows the edge of the steel strip 2. By using two sets of industrial cameras 33 to distinguish and capture images of the two edges of the steel strip 2, each industrial camera 33 only needs to cover a small area, and the actual length corresponding to a single pixel is small, thus resulting in high measurement accuracy. The drive motor 47 is activated to rotate the connected gear 48, driving the meshing... Gear 48 simultaneously drives the connected threaded rod 44 and synchronous pulley 45, and the coordinated synchronous belt 46 drives another set of synchronous pulleys 45, causing the two sets of threaded rods 44 to rotate synchronously. This drives the movable parts 49 on both sides of the threaded connection to move away from or towards each other. The movable parts 49 on both sides drive the two sets of cleaning rollers 56 to move out of the cavity shell 51 to clean the surface of the glass plate 35. During the movement, after passing the position of the ramp 42, the height difference on both sides of the fixed frame 41 will lift the direction rod 516, so that the cleaning rollers 56 can effectively contact the surface of the glass plate 35, achieving effective cleaning. At the same time, the drive motor 519 drives the two sets of cleaning rollers 56 to rotate. The sliding rod 514 is slidably connected to the cylinder 513 for rotational transmission. The connection between the cylinder 513, the universal joint 512, and the cleaning roller 56, as well as the elasticity of the spring, pushes the universal joint 512 towards the sleeve 515, effectively ensuring that the cleaning roller 56 can rotate even when its height changes. When the hemispherical ball 517 moves to the ramp 42 position on the fixed frame 41, the direction rod 516 and the sleeve 515 will lift the cleaning roller 56, or the compressed return spring 518 will pull the cleaning roller 56 down, ensuring effective transmission even when the overall drive structure is not at the same horizontal height. Finally, when the cleaning assembly 4 moves the U-shaped plates 55 on both sides... When the device is moved back into the two sets of openings 54, the vacuum cleaner 53 is activated to remove dust from the cavity shell 51 via the connecting pipe 52. Meanwhile, the drive motor 519 drives the cleaning roller 56 to rotate continuously. The rotating cleaning roller 56 drives the round block 57 and the protrusion 58 to rotate. The rotating part of the protrusion 58 contacts the fixed block 510, generating resistance that lifts the cleaning roller 56 before it rotates away. Therefore, the continuous rotation of the round block 57, combined with the elastic tension of the return spring 518, causes the cleaning roller 56 to shake up and down, shaking off the surface residue, which is then sucked away by the vacuum cleaner 53. This achieves the self-cleaning function of the cleaning roller 56, extends the subsequent processing cycle of the cleaning roller 56, and efficiently achieves the cleaning work.
