Description

Technical Field

[0001] The present invention relates to the technical field of machine vision image scanning equipment, and in particular to a machine vision image feature scanning device and a scanning method thereof. Background Art

[0002] The machine vision system uses machines to replace human eyes to make various measurements and judgments, converting the captured target into image signals, transmitting them to a dedicated image processing system, and converting them into digital signals based on pixel distribution, brightness, color and other information. The rapid development of image processing and pattern recognition technologies has also greatly promoted the development of machine vision. Existing industrial production lines already have complete machine vision systems. For example, in metal pipe production lines, scanning devices can quickly detect the outer wall of metal pipes on the assembly line, greatly improving industrial efficiency.

[0003] Among them, when the scanning device scans the outer wall of the metal pipe, it is affected by the three-dimensional pipe, resulting in one end of the pipe always being on the backlight side, and this area on the backlight side cannot be scanned and identified, affecting the detection accuracy of the equipment. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a machine vision image feature scanning device, comprising a bottom plate, four brackets are fixedly connected to the top of the bottom plate, rotating columns are rotatably connected to the inner walls of the four brackets, driving columns are fixedly connected between adjacent rotating columns, connecting belts are sleeved on the outer walls of the driving columns, a fixed soft board is fixedly connected to the outer wall of the connecting belt, a mounting belt is fixedly connected to one end of the fixed soft board away from the connecting belt, and a cleaning component is fixedly connected to the top of the connecting belt;

[0005] The scanning mechanism includes a motor fixedly connected to the top of the bottom plate, a support bracket fixedly connected to the top of the bottom plate, a detection plate fixedly connected to one end of the support bracket away from the bottom plate, a scanning instrument fixedly connected to the inner wall of the through hole of the detection plate, a gear rod fixedly connected to the side wall of the support bracket, and a correction component fixedly connected to the bottom of the detection plate;

[0006] The limiting mechanism includes a fixed plate fixedly connected to the inner wall of the mounting belt, a fixed column fixedly connected between the two fixed plates, a rotating round rod rotatably connected between the two fixed plates, a driving cylinder fixedly connected to the outer wall of the rotating round rod, and a driving gear fixedly connected to the outer wall of the rotating round rod. In view of the fact that it is difficult for the scanning instrument to fully scan the pipe pile object, a scanning mechanism and a limiting mechanism are arranged inside the equipment. When in use, the pipe to be scanned is placed in the gap between the driving cylinder and the fixed column, and the power supply of the motor and the scanning instrument is turned on. At this time, the motor drives the rotating column to drive the driving column to rotate through the output shaft. At this time, the driving column and the rotating column will drive the connecting belt, the fixed soft plate and the mounting belt to rotate synchronously, and the mounting belt will drive the internal driving cylinder to move synchronously. In the process of the driving cylinder moving, the outer wall of the driving gear will contact the bottom of the gear rod, forcing the driving gear to drive the driving cylinder to rotate. At this time, the rotation of the driving cylinder will drive the pipe on the outer wall to rotate synchronously, so that the pipe is always in a rotating state after entering the scanning area of ​​the scanning instrument. Through the application of the above components, it is ensured that the backlight surface of the pipe can also face the scanner, thereby improving the recognition efficiency of the equipment.

[0007] Preferably, the limiting mechanism further comprises a forward thread fixedly connected to the outer wall of the driving cylinder, a reverse thread fixedly connected to the outer wall of the driving cylinder, the output shaft of the motor is fixedly connected to the side wall of the rotating cylinder, and the forward thread and the reverse thread are arranged inside the device by utilizing the characteristic that the driving cylinder drives the external pipe to rotate, presenting a Figure 5 In the state shown, the connection position of the forward thread and the reverse thread is the center axis point of the driving cylinder. When the driving gear drives the driving cylinder to rotate counterclockwise, the forward thread and the reverse thread will generate a thrust toward the center axis point of the driving cylinder. For the pipe between the driving cylinder and the fixed column, if the pipe is not at the center position of the driving cylinder, the contact area between the outer wall of the pipe and the forward thread and the reverse thread will be different. If the contact area of ​​the forward thread is larger than that of the reverse thread, the thrust of the forward thread is greater than that of the reverse thread, which will force the pipe to be at the center position of the driving cylinder during operation, avoiding deviation of the pipe position and affecting the scanning results of the scanner.

[0008] Preferably, the correction assembly includes a slide rail fixedly connected to the bottom of the detection plate, a T-frame is slidably connected to the inner wall of the slide rail, and a mounting frame is fixedly connected to the bottom of the T-frame.

[0009] Preferably, the correction component also includes a plurality of rollers rotatably connected to the bottom of the mounting frame 1, the side wall of the gear rod is fixedly connected to the mounting frame 2, and the inner wall of the mounting frame 2 is rotatably connected to the roller 2. The correction component is arranged inside the device by utilizing the characteristics of the driving cylinder driving the pipeline to move, such as Figure 6As shown, the moving pipe contacts roller 2 and roller 1, and through the restriction of roller 1 and roller 2, the pipe is forced to be in the center of the driving cylinder, avoiding the pipe from deviating slightly to the left and right. After the thrusts at both ends are offset, it is difficult to push the pipe to the center.

[0010] Preferably, the correction assembly also includes a pulling spring fixedly connected to the top of the T-frame, the other end of the pulling spring is fixedly connected to the bottom of the detection plate, the inner wall of the mounting belt is rotatably connected to the outer wall of the rotating column, and the impurities after the pressurized belt is cleaned will fall on the outer wall of the connecting belt, and the outward-moving rotating cleaning frame will scratch the impurities and finally discharge them outward through the holes of the fixed soft plate.

[0011] Preferably, the cleaning assembly comprises a rotating bracket fixedly connected to the top of the connecting belt, a compressed belt is rotatably connected to the outer wall of the rotating bracket, and the outer wall of the compressed belt is meshingly connected to the outer wall of the driving gear.

[0012] Preferably, the cleaning component also includes a plurality of fixed blocks fixedly connected to the side walls of the pressurized belt, and a rotating cleaning frame is rotatably connected to the side walls of the plurality of fixed blocks. Utilizing the characteristics of the forward thread and the reverse thread rotating toward the center of the driving cylinder, a cleaning component is arranged inside the device. When the forward thread and the reverse thread rotate, the top of the corresponding pressurized belt will be driven to move inward synchronously. At this time, the pressurized belt is pushed by the forward thread, forcing the bottom of the pressurized belt to move outward. At the same time, the fixed block will drive the rotating cleaning frame to move outward synchronously. Through the application of the above-mentioned components, in the process of the pressurized belt being driven to rotate by the forward thread, the pressurized belt will clean the outer wall of the forward thread to avoid dust and impurities remaining in the pipeline from sticking to the outer wall of the subsequent pipeline, thereby reducing the scanning accuracy of the scanning instrument.

[0013] A scanning method of a machine vision image feature scanning device comprises the following steps:

[0014] S1: When in use, place the pipe to be scanned in the gap between the driving cylinder and the fixed column, and turn on the power of the motor and the scanning instrument. At this time, the motor drives the rotating column to drive the driving column to rotate through the output shaft;

[0015] S2: The driving column and the rotating column will drive the connecting belt, the fixed soft plate and the mounting belt to rotate synchronously, and the mounting belt will drive the internal driving cylinder to move synchronously;

[0016] S3: During the movement of the driving cylinder, the outer wall of the driving gear will contact the bottom of the gear rod, forcing the driving gear to drive the driving cylinder to rotate. At this time, the rotation of the driving cylinder will drive the pipe on the outer wall to rotate synchronously, so that the pipe is always in a rotating state after entering the scanning area of ​​the scanning instrument.

[0017] The present invention has the following beneficial effects:

[0018] (1) In view of the fact that it is difficult for a scanning instrument to fully scan a pipe pile object, the present invention provides a scanning mechanism and a limiting mechanism inside the device. When in use, the pipe to be scanned is placed in the gap between the driving cylinder and the fixed column, and the motor and the scanning instrument are powered on. At this time, the motor drives the rotating column to drive the driving column to rotate through the output shaft. At this time, the driving column and the rotating column will drive the connecting belt, the fixed soft plate and the installation belt to rotate synchronously. The installation belt will drive the internal driving cylinder to move synchronously. During the movement of the driving cylinder, the outer wall of the driving gear will contact the bottom of the gear rod, forcing the driving gear to drive the driving cylinder to rotate. At this time, the rotation of the driving cylinder will drive the outer wall of the pipe to rotate synchronously, so that the pipe is always in a rotating state after entering the scanning area of ​​the scanning instrument. Through the application of the above components, it is ensured that the backlight side of the pipe can also face the scanner, thereby improving the recognition efficiency of the equipment.

[0019] (2) The present invention utilizes the characteristic of the driving cylinder driving the external pipe to rotate, and sets forward threads and reverse threads inside the device, presenting a Figure 5 In the state shown, the connection position of the forward thread and the reverse thread is the center axis point of the driving cylinder. When the driving gear drives the driving cylinder to rotate counterclockwise, the forward thread and the reverse thread will generate a thrust toward the center axis point of the driving cylinder. For the pipe between the driving cylinder and the fixed column, if the pipe is not at the center position of the driving cylinder, the contact area between the outer wall of the pipe and the forward thread and the reverse thread will be different. If the contact area of ​​the forward thread is larger than that of the reverse thread, the thrust of the forward thread is greater than that of the reverse thread, which will force the pipe to be at the center position of the driving cylinder during operation, avoiding deviation of the pipe position and affecting the scanning results of the scanner.

[0020] (3) The present invention utilizes the characteristics of the positive thread and the reverse thread rotating toward the center of the driving cylinder, and a cleaning component is arranged inside the device. When the positive thread and the reverse thread rotate, the top of the corresponding pressure belt will be driven to move inward synchronously. At this time, the pressure belt is pushed by the positive thread, forcing the bottom of the pressure belt to move outward. At the same time, the fixed block will drive the rotating cleaning frame to move outward synchronously. Through the application of the above-mentioned components, in the process of the positive thread driving the pressure belt to rotate, the pressure belt will clean the outer wall of the positive thread, thereby preventing dust and impurities remaining in the pipeline from sticking to the outer wall of the subsequent pipeline and reducing the scanning accuracy of the scanning instrument.

[0021] (4) The present invention utilizes the characteristic that the driving cylinder drives the pipeline to move, and a correction component is arranged inside the device, such as Figure 6As shown, the moving pipe contacts roller 2 and roller 1, and through the restriction of roller 1 and roller 2, the pipe is forced to be in the center of the driving cylinder to avoid the pipe from deviating slightly to the left and right. After the thrusts at both ends are offset, it is difficult to push the pipe to the center. In addition, the impurities after the pressure belt is cleaned will fall on the outer wall of the connecting belt, and the outward rotating cleaning frame will scratch the impurities and finally discharge them outward through the holes in the fixed soft plate.

In view of the fact that it is difficult for the scanning device 24 to fully scan the pipe pile object, the scanning mechanism 2 and the limiting mechanism 3 are arranged inside the device. When in use, the pipe to be scanned is placed in the gap between the driving cylinder 34 and the fixing column 32, and the power of the motor 21 and the scanning device 24 is turned on. At this time, the motor 21 drives the scanning device 24 through the output shaft. The movable rotating column 12 drives the driving column 13 to rotate. At this time, the driving column 13 and the rotating column 12 will drive the connecting belt 14, the fixed soft board 15 and the mounting belt 16 to rotate synchronously. The mounting belt 16 will drive the internal driving cylinder 34 to move synchronously. During the movement of the driving cylinder 34, the outer wall of the driving gear 35 will contact the bottom of the gear rod 25, forcing the driving gear 35 to drive the driving cylinder 34 to rotate. At this time, the rotation of the driving cylinder 34 will drive the pipe on the outer wall to rotate synchronously, so that the pipe is always in a rotating state after entering the scanning area of ​​the scanning device 24. Through the application of the above components, it is ensured that the backlight side of the pipe can also face the scanner, thereby improving the recognition efficiency of the equipment.

The forward thread 36 and the reverse thread 37 are arranged inside the device by utilizing the characteristic that the driving cylinder 34 drives the external pipe to rotate, and the device is presented as follows. Figure 5 In the state shown, the connection position of the forward thread 36 and the reverse thread 37 is the center axis point of the driving cylinder 34. When the driving gear 35 drives the driving cylinder 34 to rotate counterclockwise, the forward thread 36 and the reverse thread 37 will generate a thrust toward the center axis point of the driving cylinder 34. For the pipe between the driving cylinder 34 and the fixed column 32, if the pipe is not at the center position of the driving cylinder 34, the contact area between the outer wall of the pipe and the forward thread 36 and the reverse thread 37 will be different. If the contact area of ​​the forward thread 36 is larger than that of the reverse thread 37, the thrust of the forward thread 36 is greater than that of the reverse thread 37, which will force the pipe to be at the center position of the driving cylinder 34 during operation, avoiding deviation of the pipe position and affecting the scanning results of the scanner.

[0039] The correction component 4 includes a slide rail 41 fixedly connected to the bottom of the detection plate 23, a T-shaped frame 42 is slidably connected to the inner wall of the slide rail 41, and a mounting frame 44 is fixedly connected to the bottom of the T-shaped frame 42.

The correction assembly 4 is arranged inside the device by utilizing the characteristics of the driving cylinder 34 driving the pipeline to move. Figure 6 As shown, the moving pipe contacts roller 2 47 and roller 1 45, and the pipe is forced to be in the center of the driving cylinder 34 through the restriction of roller 1 45 and roller 2 47, so as to avoid the pipe from deviating slightly to the left and right. After the thrusts at both ends are offset, it is difficult to push the pipe to the center.

[0043] The cleaning component 5 also includes a plurality of fixed blocks 53 fixedly connected to the side walls of the pressurized belt 52, and a rotating cleaning frame 54 is rotatably connected to the side walls of the plurality of fixed blocks 53. Utilizing the characteristics that the forward thread 36 and the reverse thread 37 rotate toward the center of the driving cylinder 34, a cleaning component 5 is arranged inside the device. When the forward thread 36 and the reverse thread 37 rotate, the top of the corresponding pressurized belt 52 will be driven to move inward synchronously. At this time, the pressurized belt 52 is pushed by the forward thread 36, forcing the bottom of the pressurized belt 52 to move outward. At the same time, the fixed block 53 will drive the rotating cleaning frame 54 to move outward synchronously. Through the application of the above-mentioned components, in the process of the forward thread 36 driving the pressurized belt 52 to rotate, the pressurized belt 52 will clean the outer wall of the forward thread 36 to prevent dust and impurities remaining in the pipeline from sticking to the outer wall of the subsequent pipeline, thereby reducing the scanning accuracy of the scanning device 24.

[0044] The scanning method of the scanning device comprises the following steps:

[0045] S1: When in use, the pipe to be scanned is placed in the gap between the driving cylinder 34 and the fixed cylinder 32, and the power of the motor 21 and the scanning device 24 is turned on. At this time, the motor 21 drives the rotating cylinder 12 to drive the driving cylinder 13 to rotate through the output shaft;

[0046] S2: The driving column 13 and the rotating column 12 will drive the connecting belt 14, the fixed soft plate 15 and the mounting belt 16 to rotate synchronously, and the mounting belt 16 will drive the internal driving cylinder 34 to move synchronously;

[0047] S3: During the movement of the driving cylinder 34, the outer wall of the driving gear 35 will contact the bottom of the gear rod 25, forcing the driving gear 35 to drive the driving cylinder 34 to rotate. At this time, the rotation of the driving cylinder 34 will drive the pipe on the outer wall to rotate synchronously, so that the pipe is always in a rotating state after entering the scanning area of ​​the scanning device 24.

[0048] A specific application of this embodiment is: when in use, the pipe to be scanned is placed in the gap between the driving cylinder 34 and the fixed column 32, and the power of the motor 21 and the scanning device 24 is turned on. At this time, the motor 21 drives the rotating column 12 to drive the driving column 13 to rotate through the output shaft. At this time, the driving column 13 and the rotating column 12 will drive the connecting belt 14, the fixed soft board 15 and the mounting belt 16 to rotate synchronously. The mounting belt 16 will drive the internal driving cylinder 34 to move synchronously. During the movement of the driving cylinder 34, the outer wall of the driving gear 35 will contact the bottom of the gear rod 25, forcing the driving gear 35 to drive the driving cylinder 34 to rotate. At this time, the rotation of the driving cylinder 34 will drive the outer wall of the pipe to rotate synchronously, so that the pipe is always in a rotating state after entering the scanning area of ​​the scanning device 24. Through the application of the above components, it is ensured that the backlight side of the pipe can also face the scanner, thereby improving the recognition efficiency of the equipment.

[0049] By utilizing the characteristic of the driving cylinder 34 driving the external pipe to rotate, a positive thread 36 and a reverse thread 37 are arranged inside the device, presenting a Figure 5 In the state shown, the connection position of the forward thread 36 and the reverse thread 37 is the center axis point of the driving cylinder 34. When the driving gear 35 drives the driving cylinder 34 to rotate counterclockwise, the forward thread 36 and the reverse thread 37 will generate a thrust toward the center axis point of the driving cylinder 34. For the pipe between the driving cylinder 34 and the fixed column 32, if the pipe is not at the center position of the driving cylinder 34, the contact area between the outer wall of the pipe and the forward thread 36 and the reverse thread 37 will be different. If the contact area of ​​the forward thread 36 is larger than that of the reverse thread 37, the thrust of the forward thread 36 is greater than that of the reverse thread 37, which will force the pipe to be at the center position of the driving cylinder 34 during operation, avoiding deviation of the pipe position and affecting the scanning results of the scanner.

[0050] Utilizing the characteristic that the forward thread 36 and the reverse thread 37 rotate toward the center of the driving cylinder 34, a cleaning component 5 is provided inside the device. When the forward thread 36 and the reverse thread 37 rotate, the top of the corresponding pressure belt 52 will be driven to move inward synchronously. At this time, the pressure belt 52 is pushed by the forward thread 36, forcing the bottom of the pressure belt 52 to move outward. At the same time, the fixed block 53 will drive the rotating cleaning frame 54 to move outward synchronously. Through the application of the above-mentioned components, in the process of the pressure belt 52 driven by the forward thread 36 to rotate, the pressure belt 52 will clean the outer wall of the forward thread 36 to prevent dust and impurities remaining in the pipeline from sticking to the outer wall of the subsequent pipeline and reducing the scanning accuracy of the scanning device 24. Utilizing the characteristic that the driving cylinder 34 drives the pipeline to move, a correction component 4 is provided inside the device, such as Figure 6 As shown, the moving pipe contacts roller 2 47 and roller 1 45, and the pipe is forced to be in the center of the driving cylinder 34 through the restrictions of roller 1 45 and roller 2 47, so as to avoid the pipe from deviating slightly to the left and right. After the thrusts at both ends are offset, it is difficult to push the pipe to the center. In addition, the impurities cleaned by the compressed belt 52 will fall on the outer wall of the connecting belt 14, and the outward-moving rotating cleaning frame 54 will scratch the impurities, and finally discharge them outward through the holes of the fixed soft plate 15.
