Abstract
Description
Technical Field
[0001] This utility model relates to the field of line scanning detection technology, specifically a plate-shaped line scanning detection device. Background Technology
[0002] In the field of line scanning inspection technology for steel plates, a key step in inspecting steel plates of different batches and thicknesses is to precisely adjust the vertical inspection height of the camera and light source according to the actual thickness of the steel plate to ensure the accuracy and reliability of the inspection data. In current line scanning detection devices, the camera and light source are typically supported by separate crossbars. These crossbars are installed between two opposing uprights, with both ends of the crossbars connected to the uprights via mounting bases. The mounting bases have elongated holes vertically. During assembly, bolts are passed through these elongated holes and corresponding mounting holes on the uprights to fix the mounting bases to the uprights (e.g., the movable bracket and fixed upright in patent publication number CN216013166U). When height adjustment is required, the operator must first loosen the bolts on the mounting bases at both ends of the corresponding crossbars, allowing the crossbars to move along the vertical trajectory of the elongated holes, thereby achieving height adjustment of the camera or light source. However, this traditional adjustment method has revealed several problems in practical applications: During adjustment, operators need to repeatedly tighten and loosen bolts, which is not only cumbersome but also time-consuming. More importantly, during height adjustment, the entire weight of the crossbar and the camera or light source it supports relies entirely on manual support. While this is manageable with a single camera or light source, when inspecting wider steel plates produced by large steel mills, multiple cameras or long light sources need to be placed side-by-side on the crossbar, resulting in a significant overall weight and making adjustment extremely difficult. This not only demands high physical strength from operators, easily causing fatigue, but also makes it difficult to ensure the stability and accuracy of the adjustment during support. These problems directly lead to low adjustment efficiency, severely impacting the cycle time of automated production lines and negatively affecting production efficiency. Utility Model Content
[0003] To address the technical problems existing in the background art, this utility model provides a plate-shaped line scanning detection device.
[0004] The technical solution of this utility model is as follows: A plate-shaped line scanning detection device includes a frame and a line scanning camera component and a line scanning light source component arranged horizontally on its upper and lower sides.
[0005] As the core technical concept of this utility model, the frame is also provided with an adjustment mechanism and a guide mechanism, and the line scan camera component and the line scan light source component are respectively connected to the guide mechanism through the first connecting plate and the second connecting plate.
[0006] Furthermore, the adjustment mechanism includes two sets of vertical transmission components arranged on both sides of the horizontal direction of the line scan detection component. Each set of transmission components includes: a first transmission rod and a second transmission rod arranged coaxially at the top and bottom, with their opposite ends connected in a separable manner by a locking structure; a first transmission seat and a second transmission seat respectively spirally connected to the first transmission rod and the second transmission rod, with the first transmission seat and the second transmission seat respectively connected to the first connecting plate and the second connecting plate; and a power source that drives the second transmission rod to rotate, with the two power sources able to rotate synchronously.
[0007] As one implementation, the locking structure includes a first locking shaft and a second locking shaft that is inserted into it. The first locking shaft is provided with a tightening member whose inner end is pressed against the second locking shaft. The ends of the two locking shafts that are opposite to each other are respectively connected to the first transmission rod and the second transmission rod.
[0008] Furthermore, the second locking shaft includes a connecting section and a protruding section at its upper end that is inserted into the inner side of the first locking shaft, and the lower end face of the first locking shaft abuts against the upper end face of the connecting section.
[0009] Furthermore, the outer end of the clamping member extends out of the first locking shaft, and the extended end is connected to the first rotating handle.
[0010] Furthermore, a locking rod is spirally provided on the first connecting plate, with one end of the locking rod extending out of the first connecting plate and the other end abutting against the frame.
[0011] To facilitate manual operation, a second rotating handle is provided at the end of the locking rod that extends out of the first connecting plate.
[0012] The first locking shaft and the first transmission rod, and the second locking shaft and the second transmission rod are all manufactured as a single piece.
[0013] To improve structural strength, the outer diameters of the first and second locking shafts are the same and larger than the outer diameters of the first and second transmission rods.
[0014] As a further implementation, the angles of both the line scan camera component and the line scan light source component are adjustable, and the rotation axis is perpendicular to the second transmission rod.
[0015] Furthermore, the guiding mechanism is a guide rail slider assembly, and two sets are provided corresponding to the two sets of vertical transmission assemblies.

[0017] Combination Figures 1-4 This embodiment provides a plate-shaped line scan detection device, including a frame 1 and a line scan detection assembly on it. The line scan detection assembly includes a line scan camera component 2 and a line scan light source component 3 arranged horizontally in the upper and lower directions. The line scan light source component 3 provides illumination for the line scan camera component 2. The line scan camera component 2 includes a camera base and three line scan cameras. The line scan light source component 3 includes a line scan base and three line scan light sources. The frame 1 is also provided with an adjustment mechanism 4 and a guide mechanism 5. The camera base and the line scan base are respectively connected to the guide mechanism 5 through a first connecting plate 6 and a second connecting plate 7.
[0018] Combination Figure 3 The frame 1 is a U-shaped gantry structure with the opening facing downwards, including horizontal support rods and vertical uprights at both ends. The line scan base is located below the camera base. Three line light sources are movably connected to the light source base, and three line scan cameras are movably connected to the camera base. There are no objects blocking the line scan light from below. Under the illumination of the line scan light source, the line scan light from the three line scan cameras reaches the product, thereby completing the product scanning.
[0019] Combination Figure 2The adjustment mechanism 4 includes two sets of vertical transmission components arranged on both sides of the horizontal direction of the line scan detection component. Each set of transmission components includes: The first transmission rod 41 and the second transmission rod 42 are coaxially arranged, and their opposite ends are detachably connected by a locking structure. A first transmission seat 43 and a second transmission seat 44 are respectively spirally connected to the first transmission rod 41 and the second transmission rod 42. The first transmission seat 43 and the second transmission seat 44 are respectively connected to the first connecting plate 6 and the second connecting plate 7. The power source that drives the second transmission rod 42 to rotate is a servo motor 45, and the two power sources can rotate synchronously.
[0020] The upper and lower ends of the uprights on both sides of the frame 1 are respectively provided with a first support and a second support. The ends of the first transmission rod 41 and the second transmission rod 42 that are opposite to each other are rotatably connected to the first support and the second support, respectively. The servo motors 45 on both sides are respectively located on the lower side of the corresponding second support, with the output end facing upward and connected to the lower end of the second transmission rod 42, thereby realizing the automation to replace manual adjustment of the height of the line scan camera component 2 and the line scan light source component 3, freeing up manpower.
[0021] Furthermore, the angles of both the line scan camera component 2 and the line scan light source component 3 are adjustable to adapt to different detection angle requirements, and the rotation axis is perpendicular to the second transmission rod 42.
[0022] Specifically, the camera base and the light source base have the same structure. Taking the camera base as an example, the camera base includes a first horizontal bar 21 arranged horizontally and a second horizontal bar 22 connected vertically at both ends. The second horizontal bars 22 on both sides are vertically connected to the two sides of the frame 1. The first horizontal bar 21 is perpendicular to the second transmission rod 42.
[0023] Motors can be installed on the two second crossbars 22 respectively to synchronously drive the first crossbar 21 to rotate. Alternatively, in some necessary cases, the vertical connection ends of the first crossbar 21 and the second crossbar 22 can be connected through angle adjustment seats 23. Specifically, the two ends of the first crossbar 21 are rotatably connected to the angle adjustment seats 23 at both ends, and the angle adjustment seats 23 are provided with arc-shaped grooves. Bolts can be used to fix the first crossbar 21 through the arc-shaped grooves. During adjustment, loosen the bolts, rotate the first crossbar 21, then adjust the position of the bolts in the arc-shaped grooves, and finally tighten the bolts.
[0024] The guide mechanism 5 is a guide rail slider assembly, and two sets are provided corresponding to the two sets of vertical transmission components. This design provides a stable guiding effect for the lifting and lowering of the line scan camera component 2 and the line scan light source component 3, ensuring the synchronicity of the adjustment on both sides and the smoothness of the movement, avoiding skew during the lifting and lowering process, and improving the accuracy of the adjustment.
[0025] Specifically, the guide mechanism 5 includes guide rails vertically arranged on both sides of the frame 1. Each guide rail has two sliders vertically sliding on both ends corresponding to the camera base and the light source base. The two sliders corresponding to both ends of the camera base are connected to the first transmission seat 43 through a first connecting plate 6, and the two sliders corresponding to both ends of the light source base are connected to the second transmission seat 44 through a second connecting plate 7.
[0026] Combination Figure 5 The locking structure includes a first locking shaft 46 and a second locking shaft 47 that is inserted into it. The first locking shaft 46 is spirally provided with a clamping member 48 whose inner end abuts against the second locking shaft 47. The ends of the two locking shafts, facing away from each other, are respectively connected to a first transmission rod 41 and a second transmission rod 42. This structure ensures stable transmission when the two transmission rods are locked, while also allowing for easy separation. This simplifies and simplifies the switching between synchronous and individual adjustment, improving the flexibility and reliability of the device's adjustment.
[0027] The outer end of the clamping member 48 extends out of the first locking shaft 46, and the extended end is connected to a first rotating handle. This allows the operator to easily rotate the clamping member 48 to lock and unlock the two locking shafts, simplifying the operation process of the locking structure and improving the efficiency of adjustment and switching.
[0028] The second locking shaft 47 includes a connecting section 471 and a protruding section 472 at its upper end that engages with the inner side of the first locking shaft 46. The lower end face of the first locking shaft 46 abuts against the upper end face of the connecting section 471. This structure ensures that when the protruding section 472 is inserted into the inner side of the first locking shaft 46, the lower end face of the first locking shaft 46 abuts against the upper end face of the connecting section 471, enhancing the stability of the engagement between the two locking shafts, preventing wobbling during insertion, and ensuring the accuracy of transmission.
[0029] The first locking shaft 46 and the first transmission rod 41, and the second locking shaft 47 and the second transmission rod 42 are all integrally manufactured. This facilitates one-time processing, reduces connecting parts, enhances the overall structural strength and rigidity, reduces the risk of transmission failure due to loose connections, and extends the service life of the device.
[0030] The first locking shaft 46 and the second locking shaft 47 have the same outer diameter, which is larger than the outer diameters of the first transmission rod 41 and the second transmission rod 42. This ensures the structural strength of the two locking shafts' interlocking fit, facilitates processing, manufacturing, and assembly, and avoids the problem of transmission stability being affected by excessively thin locking shafts.
[0031] Combination Figure 6 A locking rod 49 is spirally provided on the first connecting plate 6. One end of the locking rod 49 extends out of the first connecting plate 6, and the other end abuts against the upright of the frame 1.
[0032] The locking rod 49 has a second rotating handle at one end extending from the first connecting plate 6, which provides a convenient point of force for the operator to rotate the locking rod 49, making locking and unlocking operations more labor-saving and convenient, shortening operation time, and improving the ease of use of the device.
[0033] When the vertical distance that the line scan detection component needs to adjust is greater than or equal to the focal length of the line scan camera, the vertical height of the line scan camera component 2 and the line scan light source component 3 of the device can be adjusted synchronously. The specific implementation method is as follows: by rotating the first rotating handle, the locking structure at the opposite ends of the first transmission rod 41 and the second transmission rod 42 is locked, so that the two form an integral transmission rod. Then, the second rotating handle is rotated to loosen the abutment with the upright of the frame 1. At this time, the servo motors 45 on both sides of the adjustment mechanism 4 are started. Since the two servo motors 45 can rotate synchronously, they will drive the second transmission rod 42 to rotate, which in turn drives the first transmission rod 41 locked with it to rotate together. The first transmission rod 41 and the second transmission rod 42 are respectively connected by the first transmission seat 43 and the second transmission seat 44 through a screw connection, which drives the first connecting plate 6 connected to the first transmission seat 43 and the second connecting plate 7 connected to the second transmission seat 44 to rise and fall synchronously. The line scan camera component 2 and the line scan light source component 3 are respectively connected to the guide mechanism 5 through the first connecting plate 6 and the second connecting plate 7. Under the guidance of the guide mechanism 5, the two achieve synchronous vertical height adjustment on the base. When the vertical distance that the line scan detection component needs to adjust is less than the focal length of the line scan camera, the adjustment process is as follows: First, adjust the focal length of the line scan camera to adapt to the required detection range; then, adjust the vertical height of the line scan light source component 3 of the device separately. Specifically, by rotating the first rotating handle in the opposite direction to separate the locking structure at the opposite ends of the first transmission rod 41 and the second transmission rod 42, making them independent, and then rotating the second rotating handle in the opposite direction to press against the upright of the frame 1. Then, start the servo motors 45 on both sides of the adjustment mechanism 4 to drive the second transmission rod 42 to rotate. At this time, the first rotating rod is stationary relative to the second transmission rod 42. The second transmission rod 42 drives the second connecting plate 7 connected to the second transmission seat 44 to rise and fall through the second transmission seat 44 connected by a screw. The line scan light source component 3 is connected to the guide mechanism 5 through the second connecting plate 7. Under the guidance of the guide mechanism 5, its independent vertical height adjustment on the base is realized. This adjustment method eliminates the need for manual support of the line scan camera component 2 and the line scan light source component 3, as well as the need for repeated tightening of bolts, greatly reducing manpower input and freeing up manpower. At the same time, the adjustment process is convenient to operate and responds quickly, which can be well adapted to the continuous operation rhythm of the automated production line, effectively shortening the adjustment time and thus improving the overall work efficiency.
