[0002] As an important renewable resource, bamboo is widely used in the fields of construction, furniture, handicrafts, etc. During the processing of bamboo products, it is necessary to first perform rough planing, carbonization, drying, bundling, fine planing, sorting, gluing, and embryo forming on bamboo strips. In the process of bamboo processing, the sorting of bamboo strips is a key link, directly affecting the quality and production efficiency of bamboo products. After fine planing, there are still some defects such as bamboo green, wormholes, cracks, missing edges, and black knots on the bamboo strips, which affect the appearance quality of bamboo products. Traditional bamboo strip sorting mainly relies on manual operation, with problems such as low efficiency, high labor intensity, and low sorting accuracy.

[0045] Combined with Figures 1 to 20As shown in the figure, this embodiment provides a bamboo strip sorting machine, including: an input mechanism 10, a transmission mechanism 30, a detection mechanism 40, a flipping mechanism 20, and a sorting mechanism 50. Among them,

[0046] Combined with Figures 1 to 3 As shown in the figure, the input mechanism 10 is used to receive bamboo strips and input the bamboo strips into the transmission mechanism 30; the transmission mechanism 30 includes a transportation mechanism and a hydraulic push rod 31. The transportation mechanism is used to transport the bamboo strips to the entrance of the detection mechanism 40, and the hydraulic push rod 31 is adapted to push the bamboo strips into the detection mechanism; the detection mechanism 40 includes a reflector 42, an acrylic plate 41, and an industrial camera 45. The acrylic plate 41 forms a moving channel 47 for the bamboo strips; the industrial camera 45 is arranged above the side of the moving channel 47, and the reflector 42 is arranged below the industrial camera 45 and forms a preset angle with one side surface of the bamboo strip to be measured, so that the industrial camera 45 can simultaneously capture images of two adjacent sides of the bamboo strip to achieve the first detection of both sides of the bamboo strip; the flipping mechanism 20 is used to drive the bamboo strip to rotate after the first detection, make the undetected surface of the bamboo strip face upward, and is adapted to reversely send the bamboo strip into the detection mechanism 40 for secondary detection to obtain images of the other two adjacent sides of the bamboo strip; the sorting mechanism 50 is used to make the bamboo strips fall into the corresponding sorting areas according to the detection results of the detection mechanism 40 to complete the sorting of bamboo strips of different color grades or qualities. In this embodiment, the reflector forms a 45-degree angle with the acrylic plate. Through this solution, a bamboo strip sorting device based on machine vision is adopted, which can achieve a comprehensive detection of the four surfaces of the bamboo strip, and realize the front and back surface detection of the bamboo strip through the flipping mechanism, thereby improving the sorting accuracy and efficiency. At the same time, the device can automatically sort the bamboo strips according to the detection results, ensuring the sorting accuracy and efficiency, and meeting the high-precision detection requirements for the surface quality and size of the bamboo strips in the bamboo processing process.

[0047] Continuing to combine as Figures 1 to 3 As shown in the figure, the sorting mechanism includes an input mechanism 10, a flipping mechanism 20, a transportation mechanism 30, a detection mechanism 40, a sorting mechanism 50, a driving mechanism 60, and a whole machine frame 70. The input mechanism 10, the flipping mechanism 20, the transportation mechanism 30, and the detection mechanism 40 can be connected to the whole machine frame 70 through fastening screws, and the driving mechanism 60 is connected to the whole machine frame 70 through a connecting piece.

[0048] As Figures 4 to 6As shown in the figure, it is the main structure of the input mechanism 10. The input mechanism includes a conveyor belt input channel 12 connected to a slideway bracket 111, a pneumatic push rod 11, and a lower baffle 112. A plurality of pressure wheel assemblies are arranged along the length direction of the conveyor belt input channel 12. The pressure wheel assembly includes a pressure wheel bracket 116 with a first pressure wheel 117 arranged inside the slideway bracket 111. The pressure wheel bracket 116 is connected to the slideway bracket 111 through two first screws 114 and first nuts 115, and a first spring member 113 is arranged between the first screw 114 and the top surface of the pressure wheel bracket 116 to enable the first pressure wheel 117 to have an up-and-down elastic displacement amount, so as to ensure that the bamboo strips can avoid sample damage to the greatest extent when passing through the first pressure wheel 117 and adapt to bamboo strips of different diameters. The lower baffle 112 is hinged below the pressure wheel assembly for receiving the bamboo strips and is connected to the pneumatic push rod 11. The pneumatic push rod 11 is adapted to drive the lower baffle 112 to swing up and down to control the bamboo strips to slide out of the conveyor belt input channel 11 into the transmission mechanism. It should be noted that the bamboo strips in the conveyor belt input channel 12 are fed by an upstream feeding mechanism.

[0049] The transportation mechanism includes a belt transportation component 34. On both sides of the belt transportation component 34, blocking cylinders 33 are oppositely arranged, which are adapted to block the bamboo strips at the entrance of the detection mechanism, so that the hydraulic push rod 31 can push the bamboo strips into the detection mechanism 40 for detection. Here, the length of the bamboo strips is longer than the width of the belt transportation component 34. Therefore, by arranging the blocking cylinders 33 on the left and right sides of the belt transportation component 34, the bamboo strips can be blocked at the entrance position of the detection mechanism 40. The belt transportation component 34 is connected to the whole machine frame 70 through a connecting piece. The hydraulic push rod 31 is fixed to the whole machine frame 70 through a fixing plate. The blocking cylinders 33 are connected to the whole machine frame 70 through a blocking cylinder flange bracket 32.

[0050] Combined with Figures 17 to 20As shown in the figure, a driving mechanism 60 is provided in front of the entrance of the detection mechanism 40. The driving mechanism 60 includes a driving bracket 61, a driving motor bracket 62, a roller bracket 63, a driving roller 64 provided on the roller bracket 63, and a first auxiliary motor 65 installed on the driving motor bracket. A height-adjustable transmission space 66 for the bamboo strips to pass through is formed between the driving roller 64 and the driving bracket 61. The first auxiliary motor 65 is drivingly connected to the driving roller 64 to achieve forward or reverse rotation. The driving roller 64 is adapted to drive the bamboo strips in the transmission space 66 to pass through the detection mechanism 60 when rotating forward, so as to perform a photographing detection on the bamboo strips through the detection mechanism 60. Specifically, the driving bracket 61 is used to connect the driving mechanism 60 to the whole machine frame 70, and the driving motor bracket 62 is used to install the motor. The driving roller 64 is fixed through the roller bracket 63, and the first auxiliary motor 65 is connected to the driving roller 64. The driving roller 64 may be provided with a rubber outer ring to increase the friction force to facilitate driving the movement of the bamboo strips. Figure 19 and Figure 20 are respectively the schematic external views of the detection mechanism bracket 61 and the detection mechanism entrance motor bracket 62. By setting the height-adjustable transmission space 66, bamboo strips with different diameters can be adapted to enter, and the bamboo strips can also be kept stable when moving in the transmission space 66.

[0051] Combined Figure 14 and 15 As shown in the figure, the detection mechanism 40 includes a housing 46, a reflector 42, an acrylic plate 41, and an industrial camera 45 provided in the housing. The acrylic plate 41 forms a moving channel 47 for the bamboo strips. The acrylic plate 41 is transparent, so it is convenient for the industrial camera 45 to take pictures. The industrial camera 45 is provided above the side of the moving channel 47. The reflector 42 is provided below the same side of the industrial camera 45 and forms a preset angle with one side of the bamboo strip to be measured, so that the industrial camera 45 can simultaneously take pictures of the adjacent two sides of the bamboo strip to achieve the first detection of the two sides of the bamboo strip. Specifically, the reflector 45 forms a 45-degree angle with one side surface of the bamboo strip to be measured, so that the industrial camera 45 can obtain the perspectives of the upper side surface of the bamboo strip and the side surface where the reflector 42 is located at one time. After the detection is completed, the bamboo strip is flipped 180° through the flipping mechanism 20 and enters the detection mechanism 40 again to detect the other two sides, so as to obtain the surface images of the four directions of the front, back, left, and right of the bamboo strip.

[0052] The industrial camera 45 is connected to a control system, and through the control system, the surface shape characteristics, color characteristics, etc. of the bamboo strips can be identified and analyzed. Through existing image analysis techniques and in combination with the set parameter content, the bamboo strips can be classified, for example, classified according to the depth of color or category, or classified according to the flatness of the bamboo strip surface, whether there are defects such as wormholes, etc. In a preferred embodiment, a lighting source 43 is provided inside the detection mechanism 40 to improve the light during shooting.

[0053] Combined with Figures 8 to 11 As shown, the flipping mechanism 20 is arranged at the rear end of the detection mechanism 40, and it includes the flipping mechanism eight-shaped entrance 21, the flipping mechanism frame 227, and a flipping motor 23 and several integration parts 22 connected to the flipping mechanism frame 227; among them, the integration part 22 includes an upper pressing wheel frame 221, a lower pressing wheel frame 222, a second screw 223, a second spring 224, a second nut 225, and a bearing 226. Among them, the upper pressing wheel bracket 221 and the lower pressing wheel frame 222 are connected to the rotating frame 229 through two of the second screws 223 and the second nut 224, and the second spring 224 is arranged between the upper pressing wheel frame 221 and the rotating frame 229 to enable the distance between the upper pressing wheel frame 221 and the lower pressing wheel frame 222 to change elastically, that is, through the action of the second spring 224, the upper pressing wheel frame 221 can be dynamically adjusted according to the change in the diameter of the bamboo strip; second pressing wheels 228 are respectively arranged on the upper pressing wheel frame 221 and the lower pressing wheel frame 222, and an activity space 220 suitable for the bamboo strip to pass through is formed between the two second pressing wheels 228 so that the bamboo strip is suitable for entering the flipping mechanism 20; the rotating frame 229 is connected inside the bearing 226 and is connected with a flipping motor 23, and the flipping motor 23 is suitable for driving the rotating frame 229 to rotate 180° to flip the bamboo strip.

[0054] It should be noted that a second auxiliary motor (not shown) is connected to the second pressing wheel 228 of one of the integration parts 22. The second auxiliary motor is suitable for driving the second pressing wheel 228 to rotate to drive the bamboo strip to move reversely into the driving mechanism 60 after the flipping mechanism 20 flips the bamboo strip, and the driving mechanism 60 transports the bamboo strip back into the transportation mechanism; the detection mechanism 40 is suitable for taking pictures and detecting the other two sides of the bamboo strip when the bamboo strip moves reversely.

[0055] Combined with Figure 1 and Figure 17As shown, the sorting mechanism 50 includes a sorting box 52 and a linear motor 51 connected to the sorting box 52. A plurality of sorting cavities are provided in the sorting box 52. The linear motor 51 is adapted to drive the sorting box 52 to move towards the material dropping opening of the conveying mechanism according to the detection result of the detection mechanism, so that the corresponding sorting cavity can receive the bamboo strips falling from the conveying mechanism. Here, the sorting box 52 can be arranged on a linear slide rail, and the linear slide rail extends along the conveying direction of the conveying mechanism 30. By providing a plurality of sorting cavities in the same sorting box 52, the linear motor 51 can control the sorting box 52 to move different distances, so that the corresponding sorting cavity is located at the material dropping opening of the conveying mechanism to receive bamboo strips of different qualities.

[0056] In this embodiment, the driving bracket 61 is provided with an octagonal entrance to facilitate the entry of bamboo strips and prevent the bamboo strips from being difficult to enter the driving mechanism 60 due to the inclination of the end. Tapered entrance parts are provided at the front and rear ends of the moving channel 47 of the detection mechanism 40 to facilitate the entry of the end of the bamboo strip, and the transmission space 66 of the driving mechanism 60, the moving channel 47 of the detection mechanism 40, and the moving space 220 of the flipping mechanism 20 are located on the same straight line.

[0057] During operation, first, the bamboo strips enter the conveyor input channel 12 of the input mechanism 10. After the bamboo strips reach the end, the pneumatic push rod 11 controls the lower baffle 112 to open, and the bamboo strips smoothly enter the conveying mechanism. The belt conveying component 34 of the conveying mechanism conveys the bamboo strips to the entrance of the driving mechanism 40. At this time, the blocking cylinder 33 opens and the movement of the bamboo strips stops. The hydraulic push rod 31 pushes the bamboo strips into the driving mechanism 60 and then sends them into the detection mechanism 40. The detection mechanism 40 reflects through the reflector 42, and the industrial camera 45 captures the top and side images of the bamboo strips simultaneously to complete the preliminary detection. Subsequently, the bamboo strips enter the flipping mechanism 20. The flipping motor drives the rotating frame 229 to rotate 180 degrees, making the undetected surface of the bamboo strip face upward. Then, driven by the second auxiliary motor, the bamboo strips enter the detection mechanism 40 again for the detection of the back and the other side. After the detection is completed, the first auxiliary motor 65 continuously drives the driving roller 64 to rotate, driving the bamboo strips back to the conveying mechanism. The sorting mechanism 50 controls the linear motor 51 to move the sorting box 52 to a suitable position according to the detection result. The bamboo strips are conveyed to the end by the belt conveying component 34 and fall into the corresponding sorting cavity of the sorting box 52 to complete the sorting. The whole process has a high degree of automation, ensuring the comprehensiveness and accuracy of bamboo strip sorting.

[0058] In summary, the bamboo strip sorting device based on machine vision in this embodiment has a simple structure, low cost, and high sorting accuracy. It can achieve a comprehensive inspection of the four surfaces of the bamboo strip through the reflector 42 and the industrial camera 45 of the inspection mechanism. Combining with the rotation function of the flipping mechanism 20, it ensures that each surface of the bamboo strip can be accurately inspected. This device is not only applicable to the sorting of bamboo strips, but can also be extended to the sorting scenarios of other materials with similar shapes, and can quickly obtain the surface quality information and size data of the materials, thereby providing reliable data support for quality control and process optimization in the material processing process.
