Description

Technical Field

[0001] The utility model relates to the technical field of photographing and detecting wooden boards, and in particular to a detection device capable of observing defects of wooden boards at multiple angles. Background Art

[0002] Traditional inspection of the appearance of wooden boards mainly relies on manual visual inspection. This method is inefficient and easily affected by personal subjective judgment. Long-term work will cause visual fatigue and reduce the detection accuracy. With the improvement of the automation level of the wood processing industry, the requirements for the quality control of wooden boards are becoming increasingly stringent. There is a need for a detection device that can work quickly, accurately and continuously to replace manual inspection to meet the needs of large-scale production. In recent years, image processing and computer vision technology have made significant progress. CCD cameras and related software algorithms can effectively identify defects on the surface of wooden boards, such as cracks, scars, discoloration, etc., which makes automated detection possible. The application with publication number CN111781212A in the prior art discloses a visual detection device for wooden board defects, but it cannot detect wooden boards from different angles at the same time; there is currently a lack of a detection device that can observe wooden board defects from multiple angles.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following is a clear and complete description of the technical solution of the present invention in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional terms used are used to illustrate rather than limit the invention of the present invention.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Example 1: A detection device capable of observing defects of wooden boards from multiple angles, such as Figure 1-Figure 3 As shown, it includes a frame 1, on which are provided several detection mechanisms 8, and the detection mechanisms 8 include a bracket 2, which is arranged on the frame 1, on which are provided a linear slide 10 and a light board 7, on which are provided a crossbar 4, on which is provided a CCD camera 6; the two light boards 7 are symmetrically arranged, and the CCD camera 6 is arranged between the two light boards 7; the frame 1 is provided with a board platform, and the CCD camera 6 is combined with the linear slide 10 to ensure high resolution and stability of image acquisition, thereby improving the accuracy of defect identification. The utility model can perform comprehensive inspection of wooden boards from multiple angles by having multiple detection mechanisms 8 working simultaneously or sequentially, which is faster and more comprehensive than single-angle inspection, significantly improving the inspection rate, and being suitable for the needs of high-speed production lines; the CCD camera 6 is combined with the precision linear slide 10 to ensure high resolution and stability of image acquisition, thereby improving the accuracy of defect identification.

[0021] Example 2: A detection device capable of observing defects in wooden boards from multiple angles. The frame 1 is surrounded by backlight panels. Five detection mechanisms 8 are mounted on the frame 1, located above, below, to the left, upper left, and upper right of the board platform. A CCD camera 6 and a light panel 7 face the board platform. The board platform includes two support rods 3, each with a retaining groove between them. This allows the detection device to accommodate wooden boards of varying sizes and shapes, increasing the device's versatility and flexibility. Roller conveyors are located on both sides of the board platform. These conveyors allow wooden boards to automatically enter and exit the inspection area, reducing the need for manual handling, labor intensity, and labor costs. The specific structure of the roller conveyor is prior art and will not be described in detail here. The linear slide 10 includes a guide rail with a slider mounted on it. The slider is secured to a lead screw nut, which is threadedly connected to a lead screw lever, which is connected to a drive motor via a coupling. The light panel 7 is fixedly connected to the bracket 2 via a connecting block 5, and the CCD camera 6 is fixedly connected to the crossbar 4 via a mounting block 9. All other aspects are the same as in Example 1.

[0022] The plank to be tested is first fed onto the plank platform via a roller conveyor. Support rods 3 on the platform ensure stable positioning of the plank, while retaining grooves help position the plank for testing. The linear slide 10 of each testing mechanism 8 adjusts the CCD camera 6 to the optimal testing position according to preset programs or parameters, ensuring the camera is aligned with the plank's surface to be tested. Light panels 7 are activated, providing ample illumination to ensure that the CCD camera 6 clearly captures the plank's surface features. Once the plank reaches the predetermined position, the CCD camera 6 of each testing mechanism 8 begins operating, capturing images of the plank from various angles. The captured image data is transmitted to a central control system, where it is analyzed using image processing algorithms to identify surface defects such as cracks, scratches, scars, and color variations. Once the current plank has been tested, the roller conveyor moves it out of the testing area and the next plank is fed in, repeating the testing process. This entire process is automated, improving testing efficiency.

[0023] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
