[0039] The following will further illustrate the technical solution of the present utility model in conjunction with the attached Figures 1 to 6 drawings and through specific embodiments.

[0040] A scanning device includes a mounting base 1, a first conveying mechanism 2, a second conveying mechanism 3, a light source, a scanning assembly 4, and a mounting bracket 5;

[0041] The first conveying mechanism 2 and the second conveying mechanism 3 are horizontally mounted on the mounting base 1. The second conveying mechanism 3 is located below the first conveying mechanism 2, and the scanning assembly 4 is mounted above the first conveying mechanism 2 through the mounting bracket 5;

[0042] The detection end of the scanning assembly 4 is arranged vertically downward, and a scanning area is formed below;

[0043] The light source is mounted on the mounting bracket 5, and the light source is used to provide illumination for the scanning area;

[0044] The first conveying mechanism 2 is used to convey materials forward from the rear through the scanning area;

[0045] The second conveying mechanism 3 is used to convey the materials output from the output end of the first conveying mechanism 2 backward from the front.

[0046] In this utility model, the first conveying mechanism 2 conveys materials to the scanning area for scanning. When the materials are output from the discharge end of the first conveying mechanism 2 and fall downward, the second conveying mechanism 3 below receives the materials and conveys the materials backward to the input end of the scanning device, realizing the continuous processing and flow of materials, avoiding the accumulation of materials at the end of the first conveying mechanism 2 after scanning, and thus improving the overall processing efficiency. Since the materials are continuously conveyed and scanned, it reduces the need for staff to clean up the materials at the end of the scanning device after each material scanning and identification, reducing the labor operation cost and error rate, and at the same time improving the work safety.

[0047] The light source is provided to illuminate the materials passing through the scanning area. When the materials are conveyed through the scanning area by the first conveying mechanism 2, the scanning component 4 installed above the scanning area scans the surface of the materials, and transmits the scanned image through a signal to the storage for preservation and processing, so as to analyze and obtain the distribution of defects or patterns on the surface of the materials, ensuring the accuracy of subsequent cutting processes.

[0048] The arrangement of the first conveying mechanism 2 and the second conveying mechanism 3 distributed vertically reduces the occupied space, and the entire scanning device structure is more compact.

[0049] This application realizes the continuous scanning and conveying of materials by setting the first conveying mechanism 2 to convey materials into the scanning area and the second conveying mechanism 3 to collect and return the scanned materials, improving the work efficiency and scanning accuracy, reducing the labor operation cost and error rate, and having significant beneficial effects.

[0050] Furthermore, it further includes a receiving hopper 6, and the receiving hopper 6 is arranged below the discharge end of the second conveying mechanism 3.

[0051] By adding the receiving hopper 6, the materials output from the discharge end of the second conveying mechanism 3 can be conveniently collected. In this way, after being scanned and conveyed, the materials can directly fall into the receiving hopper 6, further improving the work efficiency; it also eliminates the need for staff to frequently clean up materials at the front end (the discharge end of the first conveying mechanism 2) of the scanning device, thus reducing the safety risks that staff may face during the operation process. In addition, the design of the receiving hopper 6 can ensure that the materials will not scatter or be lost during the conveying process, reducing the waste and loss of materials, which is of great significance for cost control.

[0052] To further illustrate, the material receiving hopper 6, as a component of the scanning device, enhances the functionality and integrity of the entire device. It not only facilitates the collection of materials but also makes the entire scanning and conveying process smoother and more efficient. The materials that have completed scanning and identification are collected in the material receiving hopper 6, where they can be conveniently processed subsequently, such as classified and packed. This orderly material management method helps to improve the operating efficiency of the entire production line.

[0053] Furthermore, the first conveying mechanism 2 includes a first motor 21, two first conveying rollers 22, and a first belt 23;

[0054] The two first conveying rollers 22 are respectively arranged on the front and rear sides of the mounting seat 1. The first belt 23 is sleeved on the outer sides of the two first conveying rollers 22. The first motor 21 is used to drive one of the first conveying rollers 22 to rotate;

[0055] The second conveying mechanism 3 includes a second motor 31, two second conveying rollers 32, and a second belt 33;

[0056] The two second conveying rollers 32 are respectively arranged on the front and rear sides of the mounting seat 1. The second belt 33 is sleeved on the outer sides of the two second conveying rollers 32. The second motor 31 is used to drive one of the second conveying rollers 32 to rotate.

[0057] By adopting the structure of two conveying rollers 22 / 32 and one belt 23 / 33, the design of the conveying mechanism is simplified, and the manufacturing cost is reduced. At the same time, this structure is stable and reliable, which can ensure the smoothness and accuracy of the materials during the conveying process. Each conveying mechanism is driven by a motor to rotate one conveying roller, thereby driving the belt to move. This design makes the conveying speed easy to control and can be adjusted according to needs to adapt to different materials and scanning requirements.

[0058] To further illustrate, for the first conveying mechanism 2, since the two first conveying rollers 22 are respectively located on the front and rear sides of the mounting seat 1, it can provide sufficient support and stability for the materials conveyed by the first belt 23, enabling the materials to pass through the scanning area smoothly and continuously.

[0059] In addition, a speed reducer can be added to the output end of the motor 21 / 31 to facilitate the adjustment of the rotation speed of the conveying roller 22 / 32. By adjusting the feeding speed of the conveying roller 22 / 32, the speed of the materials passing through the scanning area can be specifically adjusted.

[0060] Further, an adsorption flat plate 71 is provided between the two first conveying rollers 22. The adsorption flat plate 71 is installed on the mounting base 1. The adsorption flat plate 71 is provided with a number of through holes. The through holes are connected to an air extraction pump 72 through a pipeline 73. The pipeline 73 is installed below the adsorption flat plate 71.

[0061] The first belt 23 is wound around the two first conveying rollers 22 and outside the adsorption flat plate 71. The through holes of the adsorption flat plate 71 are communicated through the air extraction pump 72 and the pipeline 73. The air extraction pump 72 will extract air from the upper surface of the adsorption flat plate 71, creating a negative pressure above the adsorption flat plate 71, so that the material conveyed through the adsorption flat plate 71 is stably adsorbed, making the surface of the material reach the unfolded effect, which is beneficial to scanning the true situation of the material surface and improving the quality and accuracy of scanning.

[0062] The air below can be extracted, thus forming a relatively stable air environment above the mounting base. This helps to reduce the influence of air flow on the scanning result. Especially for those materials that require high-precision scanning, this improvement can significantly improve the scanning quality and accuracy.

[0063] Further, it further includes a baffle 8 in the shape of a long plate. The baffle 8 extends along the width direction of the mounting base 1. The two ends of the baffle 8 are respectively detachably installed and connected to the mounting base 1;

[0064] The vertical cross-section of the baffle 8 is inclined and curved from top to bottom. The upper end of the baffle 8 is located in front of the discharge end of the first conveying mechanism 2, and the lower end of the baffle 8 is located above the second belt 33.

[0065] The inclined and curved baffle 8 is detachably arranged on the mounting base 1, which can effectively guide the material output from the first conveying mechanism 2 to smoothly transition to the second conveying mechanism 3, avoiding the situation of material accumulation at the discharge end of the first conveying mechanism 2, and ensuring the continuity and stability of the material during transmission, reducing the possible scattering or deviation of the material during the transition process.

[0066] Further, the scanning assembly 4 includes a number of industrial cameras;

[0067] The mounting frame 5 includes two vertical frames 51, a cross beam 52 and a number of adjusting brackets 53. The two vertical frames 51 are installed on both sides of the mounting base 1 in the width direction. The cross beam 52 is horizontally arranged on the tops of the two vertical frames 51. The adjusting brackets 53 are detachably connected to the cross beam 52. The industrial cameras are linearly arranged on the cross beam 52 through the adjusting brackets 53.

[0068] Industrial cameras usually have high resolution and high sensitivity, and can capture fine defects and textures on the material surface. By arranging multiple industrial cameras linearly, the material can be covered and scanned over a large range, obtaining more comprehensive and accurate image information.

[0069] The industrial camera is installed above the mounting base 1 through the vertical frames 51, the cross beam 52 and several adjusting brackets 53. The mounting frame 5 formed by the two vertical frames 51 and the cross beam 52 has a stable and reliable structure, which can ensure that the industrial camera maintains a stable position and angle during the scanning process. At the same time, this design can also reduce the influence of vibration and interference on the scanning results, improving the overall stability and reliability.

[0070] Furthermore, the adjusting bracket 53 includes two vertical plates 531 and a cross plate 532. The two vertical plates 531 are arranged relatively parallel, and the cross plate 532 is arranged between the two vertical plates 531;

[0071] The vertical plate 531 is provided with a vertical groove 5311 along its length extension direction, the cross plate 532 is provided with a horizontal groove 5321 along its length direction, both ends of the cross plate 532 are installed and connected with the vertical groove 5311 through fasteners, and the industrial camera is installed and connected with the horizontal groove 5321 through fasteners.

[0072] Since both ends of the cross plate 532 are installed and connected with the vertical groove 5311 through fasteners such as screws, the cross plate 532 can move up and down in the vertical groove 5311, thus realizing the position adjustment of the industrial camera in the vertical direction; the industrial camera is installed and connected with the horizontal groove 5321 through fasteners such as screws, so that the industrial camera can move left and right in the horizontal groove 5321, thus realizing the position adjustment of the industrial camera in the horizontal direction. Through the settings of the vertical groove 5311 and the horizontal groove 5321, the position of the industrial camera can be accurately adjusted and fixed through fasteners, ensuring the accuracy and reliability of the scanning results and improving the overall performance of the scanning device.

[0073] Further, it also includes a light shield 91. The light shield 91 is arranged around the mounting frame 5, and the light shield 91 surrounds the light source and the scanning assembly 4.

[0074] The light shield 91 is arranged around the mounting frame 5, and the light shield 91 can effectively block external light from entering the scanning area, thereby reducing the interference of ambient light on the scanning results.

[0075] The light shield 91 surrounds the light source and the scanning assembly 4, enabling the light source inside the device to irradiate the material to be scanned more concentratedly and effectively. This design improves the utilization rate of the light source, making the scanning results clearer and more accurate.

[0076] In addition, the light shield 91 serves as a physical barrier that can, to a certain extent, protect the scanning component 4 and the light source from direct impact or damage by external objects, thereby extending the service life of the scanning device.

[0077] Furthermore, it further includes a display screen 92, and the display screen 92 is disposed on the light shield 91 at the front end.

[0078] The display screen 92 can display the working status, scanning results or other relevant information of the scanning device in real time. This provides instant feedback to the user, enabling the user to quickly understand the operating conditions and scanning results of the scanning device, and improving work efficiency.
