Description

Technical Field

[0001] This utility model relates to the field of wood board quality testing technology, specifically to an automatic detection device for grading the surface quality of oriented strand board. Background Technology

[0002] Timber testing is an essential and important step. Wood panels are the most in-demand type of wood, especially particleboard. Surface defects are one of the important indicators for judging the quality of wood panels. As the wood processing industry develops towards large-scale mechanized and automated production, people are paying more and more attention to the processing quality of wood panels, especially surface defects. Therefore, surface quality testing technology is becoming increasingly important.

[0003] There are many methods for detecting defects in boards. Traditional detection methods mostly rely on manual methods. Manual detection depends on the experience and judgment of the operators. Different operators may have different standards for identifying defects, which can easily lead to human error and deviation, especially for some small or inconspicuous defects. In addition, manual inspection is not only slow, but may also lead to a significant decrease in production efficiency. To address the above problems, an automatic detection device for grading the surface quality of oriented strand board is proposed. Utility Model Content

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Reference Figure 1-4 As shown, an automatic surface quality grading and inspection device for oriented strand board (OSB) includes a fixed platform 5. A raw material conveyor belt 1 is located on the left side of the fixed platform 5, and a defective product conveyor belt 2 is located behind the fixed platform 5, specifically used to transport boards judged to be defective, achieving rapid isolation and processing of defective products. A qualified product conveyor belt 3 is located on the right side of the fixed platform 5, ensuring that boards that have passed inspection and are judged to be qualified can be smoothly and efficiently transported to the next process or storage area. A non-qualified product conveyor belt 4 is located in front of the fixed platform 5, used to transport boards judged to be non-qualified, similar to the defective product conveyor belt 2, achieving... To facilitate rapid isolation of defective products, a steering assembly 13 is installed in the center of the upper surface of the fixed platform 5. Support frames 6 are fixedly connected to the front and rear sides of the fixed platform 5. Connecting rods 7 are fixedly connected to the left and right sides of the two sets of support frames 6. Two adjusting rods 8 are fixedly installed between the two connecting rods 7. Mounting seats 9 are installed on the surface of the two adjusting rods 8. A vision CCD 10 is fixedly installed at the bottom of the mounting seat 9 and directly above the steering assembly 13. By adjusting the position of the adjusting rods 8 and the mounting seat 9, it can be ensured that the vision CCD 10 can always accurately capture the image information of the wooden board, thereby improving the accuracy and flexibility of the inspection.

[0020] Specifically, the steering assembly 13 includes a rotating platform 1301, which is rotatably connected to the middle of the upper surface of the fixed platform 5. A base plate 1302 is fixedly connected above the rotating platform 1301, and side plates 1303 are fixedly connected to both the front and rear sides of the upper surface of the base plate 1302.

[0021] Specifically, rotating shafts 1304 are rotatably connected to both sides of the two side plates 1303. Transmission wheels 1305 are fixedly connected to the front and rear ends of the outer surfaces of the two rotating shafts 1304. A conveyor belt 1306 is connected between the transmission wheels 1305 on the left and right sides.

[0022] Specifically, a first synchronous pulley 1307 is fixedly connected between the outer surface of the right rotating shaft 1304 and the two transmission wheels 1305. A servo motor 1308 is fixedly installed on the upper surface of the base plate 1302. A second synchronous pulley 1309 is fixedly connected to the output end of the servo motor 1308. The second synchronous pulley 1309 is synchronously connected to the first synchronous pulley 1307 via a synchronous belt.

[0023] Specifically, a stepper motor 1310 is fixedly connected to the bottom of the fixed platform 5. The output end of the stepper motor 1310 passes through the bottom of the fixed platform 5 and is fixedly connected to the bottom surface of the rotating platform 1301. The auxiliary steering component 13 of the stepper motor 1310 can precisely control the conveying path of the wooden board, thereby improving the accuracy and efficiency of classification.

[0024] Specifically, a fixing plate 11 is fixedly connected to the upper left side of the front support frame 6, and a controller 12 is fixedly installed on the upper part of the fixing plate 11. The controller 12 can judge the image information according to the preset algorithm and threshold, and issue corresponding control commands to ensure that the wooden board can be correctly classified and processed according to its quality grade.

[0025] Working Principle: In operation, untested wooden boards are conveyed via the raw material conveyor belt 1 to the top of two conveyor belts 1306. A vision CCD 10 then captures an image of the board, which is transmitted to the controller 12 for analysis. The controller 12 determines the board's suitability based on the image and sends a control signal to the stepper motor 1310, causing it to rotate forward, reverse, or remain stationary. The servo motor 1308 then drives the second synchronous pulley 1309 to rotate, which in turn drives the rotating shaft 1304 via the synchronous belt and the first synchronous pulley 1307. The stepper motor 1310 rotates, thus sending the inspected wooden board out of the steering assembly 13. When the output end of the stepper motor 1310 rotates forward, it drives the rotating table 1301 to rotate, so that the direction of the wooden board discharged by the steering assembly 13 is aligned with the defective product conveyor belt 2, that is, the wooden board is actually a defective product after inspection. When the output end of the stepper motor 1310 rotates in reverse, it drives the rotating table 1301 to rotate, so that the direction of the wooden board discharged by the steering assembly 13 is aligned with the unqualified product conveyor belt 4, that is, the wooden board is actually an unqualified product after inspection. Similarly, when the output end of the stepper motor 1310 does not rotate, the wooden board is a qualified product and is output by the qualified product conveyor belt 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
