[0024] The present invention provides the following embodiments

[0025] Example 1

[0026] The embodiment of the present invention provides a width measuring device, such as Figure 1-Figure 4As shown, it includes a work frame 1, in which a conveying mechanism 3 is installed, a U-shaped support frame 4 is distributed front and rear on the upper end of the work frame 1, a sliding block 6 is slidably provided on the upper end of the U-shaped support frame 4 distributed front and rear along the left and right direction, and a telescopic rod 7 is symmetrically provided on the front and rear sides of the lower end of the sliding block 6, the telescopic rod 7 is fixedly connected to the upper end of the mounting plate 8, and the lower end of the mounting plate 8 is fixedly connected to the U-shaped plate 9, and the U-shaped plate 9 is quickly installed with a width measuring component through a quick release mechanism, and the width measuring component is correspondingly arranged on the upper side of the conveying mechanism 3, and the width measuring component is electrically connected to the image processing module, and the image processing module includes an angle correction module and a width measuring module;

[0027] The conveying mechanism 3 is a belt conveying mechanism, which is used to convey the material to be measured.

[0028] The beneficial effects of the above technical solution are:

[0029] The quick-release mechanism can realize the rapid installation and disassembly of the width measuring component and the U-shaped plate 9. The sliding block 6 can slide left and right along the U-shaped support frame 4, thereby driving the telescopic rod 7 to move left and right, thereby driving the U-shaped plate 9 to move left and right. The telescopic rod 7 drives the mounting plate 8 to move up and down, and the mounting plate 8 drives the U-shaped plate 9 to move up and down, thereby realizing the adjustment of the position of the U-shaped plate 9 in the left and right directions and the up and down directions, so that the width measuring component installed in the U-shaped plate 9 can take pictures of the material to be measured transmitted on the conveying mechanism 3. The angle correction module can judge the horizontal inclination angle of the material to be measured and automatically correct the image, which solves the technical problem that the traditional width measuring equipment does not take into account the diversity of horizontal angles when placing materials in actual production during design, lacks an intelligent correction mechanism for the horizontal angle inclination, and leads to errors in the width measurement results.

[0030] Example 2

[0031] On the basis of Example 1, Figure 1-Figure 4 As shown, the width measurement assembly includes a color mark sensor and a camera 5. The color mark sensor is electrically connected to the camera 5 through a controller. The color mark sensor is used to equip different types of materials to be measured with color marks of different colors or patterns. The camera 5 is used to photograph the materials to be measured.

[0032] The angle correction module is used to correct the image of the material to be measured taken by the camera 5, and the width measurement module is used to measure the width of the corrected image of the material to be measured.

[0033] The beneficial effects of the above technical solution are:

[0034] A highly sensitive color mark sensor is introduced, which can automatically identify color marks of different colors and modes. The color mark sensor is connected to the camera 5 through a controller, and the color mark sensor monitors the color mark on the surface of the material to be measured in real time. The color mark sensor triggers the camera 5 through the controller to capture a high-resolution image. The color mark sensor and the camera 5 and the color mark sensor triggers the camera 5 through the controller to capture a high-resolution image. The technical means of the color mark sensor and the camera 5 and the color mark sensor triggering the camera 5 through the controller to capture a high-resolution image all adopt the existing technology, which will not be described in detail in the present invention. When the angle correction module determines the inclination angle of the material to be measured and automatically corrects the image, the following method is adopted: first, the edge of the image is corrected. Enhance and binarize the image, then count the number of pixels in the image that are symmetrical on the left and right sides when each pixel is used as the symmetry axis, and use the number of symmetrical pixels obtained by counting as the score of the corresponding symmetry axis, and record the highest score Fn among all symmetry axis scores, where n is the rotation angle relative to the initial image, and is a rational number between 0 and 360 degrees; after completing the 360-degree rotation and statistics relative to the initial image, find the maximum value of all Fn, where n is the angle that needs to be corrected for the initial image (refer to CN201610268727 - A method for correcting the horizontal angle of an image object);

[0035] The width measurement module is used to measure the width of the corrected image of the material to be measured using the following method: use Python language to process the corrected image, obtain the number of pixels corresponding to the width of the image of the material to be measured, convert the pixel scale, and calculate the actual width of the material to be measured through the number of pixels (refer to CN201910959745-A building crack width measurement algorithm and method based on image processing).

The elastic force of the spring 18 is large enough, and the L-shaped connecting rod 15 drives the clamping plate 20 to clamp and fix the left and right ends of the camera 5. After the clamping plate 20 contacts the camera 5 and cannot move, the fixing rod 19 continues to rotate. At this time, the L-shaped connecting rod 15 slides along the clamping plate 20, bringing The movable sliding shaft 17 slides along the sliding cavity 16, and the spring 18 is deformed until the clamping plate 23 clamps and fixes the lens of the camera 5, and the setting of the clamping plate 23 can prevent the camera 5 from falling. The fixed shaft 22, the clamping plates 23 on the upper and lower sides and the fixed rod 19 connected thereto form a scissor-type structure, and then the bolt 11 is tightened to prevent the threaded rod 14 from moving forward. At the same time, when the threaded rod 14 moves backward, the clamping plate 1 20 and the clamping plate 23 will continue to move toward each other, thereby ensuring the stability of the installation of the camera 5 in the installation cavity 10. The lower end of the U-shaped plate 9 is an open structure, which is convenient for the lens of the camera 5 to shoot the material to be measured. The setting of the quick-release mechanism can realize the rapid installation and disassembly of the camera 5 in the installation cavity 10 by controlling the bolt 11 and the operating block 13.

A liquid inlet passage 51 is provided inside the connection block 3 50. The liquid inlet passage 51 is connected with the push cavity 44 through the liquid inlet hole. The upper end of the cleaning block 52 contacts the lower end of the glass 53. The left and right ends of the glass 53 correspond to the installation grooves. The installation grooves are correspondingly arranged at the left and right ends of the installation cavity 10. The end of the push block 45 away from the connection block 1 46 is rotatably connected with the rotating rod 1 47. The rotating rod 1 47 is eccentrically connected with the disc 48.

[0044] A motor 26 is fixedly provided at the middle of the upper end of the U-shaped plate 9, and the motor 26 is fixedly connected to the rotating shaft 27, and the rotating shaft 27 is fixedly connected to the fan 40.

[0046] The beneficial effects of the above technical solution are:

[0047] By setting the glass 53, the lens of the camera 5 is prevented from being polluted by external dust. When the camera 5 is cooled, the motor 26 is started, the motor 26 drives the rotating shaft 27 to rotate, and the rotating shaft 27 drives the fan 40 to rotate. When the fan 40 rotates, the air flows into the heat dissipation cavity 33 through the air inlet 36, and then flows into the installation cavity 10 through the heat dissipation cavity 33 to dissipate the heat of the camera 5, and finally flows out through the air outlet 37.

The cleaning liquid is sprayed on the surface of the glass 53 through the liquid inlet passage 51. When the push block 45 moves in the direction away from the groove 43, the cleaning liquid in the cleaning chamber 41 flows into the push chamber 44 through the through hole 2 42 to replenish the push chamber 44. The push block 45 drives the connecting block 2 49 to move back and forth through the connecting block 1 46. The connecting block 2 49 drives the connecting block 3 50 to move. The connecting block 3 50 drives the cleaning block 52 to move left and right.

When the camera 5 is working, the cleaning block 52 is in the open groove 54, and the motor 26 stops working to prevent the cleaning block 52 from affecting the normal operation of the camera 5.

[0049] The functional components of the present invention include heat dissipation and cleaning functions, so that the camera 5 can maintain normal operation for a long time.
